If issued, the City will offer the 2016 New Money Bonds pursuant to a separate official statement.
The City has the authority to issue an additional $500 million of PFC Obligations. Within the first six months of 2017, the City plans to issue PFC Obligations (the "2017 PFC Bonds") to pay the costs of certain projects included in the O'Hare Modernization Program (the "OMP"), fund the related reserve requirements, refund certain outstanding PFC Obligations and pay the related costs of issuance of the 2017 PFC Bonds, as more fully described under "PLAN OF FINANCE" herein.



* Preliminary, subject to change.

The City previously authorized the issuance of Chicago O'Hare International Airport Commercial Paper Notes (the "CP Notes") and Chicago O'Hare International Airport Credit Agreement Notes (the "Credit Agreement Notes"), respectively, in a combined aggregate principal amount outstanding at any one time of up to $1 billion. Pursuant to this authority, the City recently established a $420 million CP Notes program and intends to establish a $180 million program for the issuance of Credit Agreement Notes. The CP Notes and the Credit Agreement Notes (if and when issued) are Junior Lien Obligations and are subordinate to the 2016 Senior Lien Bonds and all other Senior Lien Obligations with respect to their claim on Revenues. See "OUTSTANDING INDEBTEDNESS AT O'HARE."

The City expects to issue additional Airport Obligations, including Senior Lien Bonds, PFC Obligations, CP Notes and Credit Agreement Notes (each as herein defined), from time to time, to continue implementation and funding of capital projects at O'Hare and refunding Outstanding Airport Obligations. For a discussion of future financing needs for O'Hare, .see "CAPITAL PROGRAMS-OMP Airfield Projects" and APPENDIX E "REPORT OF THE AIRPORT CONSULTANT-The Airport Facilities, Capital Program and 2016 Projects."

Security for the 2016 Senior Lien Bonds

2016 Senior Lien Bonds. The 2016 Senior Lien Bonds will be secured under the Senior Lien Indenture by a lien on and pledge of all Revenues and will be payable from amounts that may be withdrawn -from the Debt Service Fund created under the Senior Lien Indenture and in the case of the 2016C Senior Lien Bonds through Fiscal Year 2018, from amounts that may be withdrawn from the 2016C Senior Lien Bond PFC Revenue Deposit Account (as herein-defined) created under the Fifty-Fourth Supplemental Indenture. The following table sets forth the pledged security for each Series of 2016 Senior Lien Bonds:
Refunding Series Pledged Security
2016A Revenues
2016B Revenues
2016C Revenues and PFC Revenues through 2018
See "SECURITY FOR THE 2016 SENIOR LIEN BONDS - Pledge of Revenues and PFCs."
For purposes of this Official Statement, the term "Senior Lien Obligations" refers to the 2016 Senior Lien Bonds, all Outstanding Senior Lien Bonds, and other obligations of the City payable from Revenues, other than Junior Lien Obligations, including any obligations of the City under a Qualified Senior Lien Swap Agreement and obligations incurred by the City to reimburse the issuers of any letters of credit or bond purchase agreements securing one or more Series of Senior Lien Bonds; the term "Junior Lien Obligations" refers to CP Notes, Credit Agreement Notes, and other obligations payable from amounts to be withdrawn from the Junior Lien Obligation Debt Service Fund; and the term "Airport Obligations" refers to and includes all obligations payable from Revenues, including Senior Lien Obligations and Junior Lien Obligations.
The 2016 Senior Lien Bonds will be secured on a parity basis as to the Revenues with the Outstanding Senior Lien Bonds, which are currently outstanding in the aggregate principal amount of $6,400,885,000 (which amount includes Outstanding Senior Lien Bonds anticipated to be refunded with a portion of the proceeds of the 2016 Senior Lien Bonds). Subject to certain requirements set forth in the Senior Lien Indenture, the City may issue or incur additional Senior Lien Obligations that will be secured on a parity basis with the 2016 Senior Lien Bonds and the Outstanding Senior Lien Bonds. Sec "SECURITY FOR THE 2016 SENIOR LIEN BONDS-Issuance of Additional Senior Lien Bonds."
The Senior Lien Indenture requires that all Revenues be deposited in the Revenue Fund held by the Trustee and be applied in accordance with the flow of funds as provided in the Senior Lien Indenture. Pursuant to the Senior Lien Indenture, moneys and securities held by the City in the Airport Development
|1010|
Fund and the Airport General Fund may be applied, used and withdrawn by the City for any lawful corporate purpose. See "SECURITY FOR THE 2016 SENIOR LIEN BONDS-Flow of Funds," and APPENDIX B "SUMMARY OF CERTAIN PROVISIONS OF THE SENIOR LIEN INDENTURE." The Senior Lien Indenture also provides that the City will comply with all valid acts, rules, regulations, orders and directives of any governmental, legislative, executive, administrative or judicial body applicable to O'Hare, unless the City contests'them in good faith, all to the end that O'Hare will remain operational at all times.

As a recipient of federal grants for O'Hare, the City is required by federal law, including, without limitation, grant assurances applicable to the City under grant agreements with the Federal Aviation
. Administration. ("FAA"),Jo_^ _
or operating costs of O'Hare/the local airport system; or other local facilities which are ownedior operated; by the City arid directly arid substantially related to the air transportation of passengers or property. Any diversion by the City ofrevenues generated at O'Hare, including the! Revenues,5 in violation of-fcdcral law or the City's grant assurances, would subject the City to potential enforcement actions-by the FAA^and might result in a default under the Senior Lien Indenture, which, upon becoming an Event of Default under the Senior Lien Indenture, could result in the exercise by'the Trustee of the remedies under the Senior Lien Indenture. See "SECURITY FOR THE 2016 SENIOR LIEN BONDS-O'Hare Revenues Must Be Used For1 Airport Purposes:" ;

- Moneys deposited by the City: as-Revenues in accordance with the Senior Lien^Indenture include rentals, fees and charges imposed upon the Airline Parties'(as herein defined) under the Airport Use Agreements (as herein defined). The Airport Use Agreements provide that the aggregate of all rentals, fees and'charges to be paid by the Airline Parties shall be sufficient to pay for the net cost of operating, maintaining and developing O'Hare (excluding the Land Support Area, as herein defined), including the satisfaction of all of the City's obligations to make deposits and payments under the Senior Lien Indenture. See "SECURITY FOR THE 2016 SENIOR LIEN BONDS-Airport Use Agreements." The expiration date for all of the Airport Use. Agreements is May 11, 201.8. Upon the expiration of the Airport Use Agreements, the City may extend such agreements, enter into new agreements with the airlines, or impose rates and charges upon the airlines by City ordinance consistent with the requirements of federal law. Regardless of which of these options is pursued, the Ci ty has covenanted in the Senior Lien Indenture (which will rerriain in'effect beyond the expiration of the Airport Use Agreements) to establish rentals, rates and other charges for the use and operation of O'Hare such that Revenues (including rentals, fees and charges'iriiposed on the airlines), together with certain other moneys deposited with the' Trustee, are sufficient to pay the "Operation and Maintenance Expenses" (as defined in APPENDIX A) at O'Hare arid to.satisfy the debt service coverage covenants contained in the Senior Lien Indenture. See "SECURITY FOR THE 2016 SENIOR LIEN BONDS-Debt Service Coverage Covenants" and "Airport Use Agreements." Thus, while it is not possible to predict whether any airline will be contractually obligated to make payments, including, among other things, for debt service on the 2016 Senior Lien Bonds, the Outstanding Senior Lien Bonds or any other Senior Lien Bonds after the expiration date of the Airport Use Agreements in 2018, the City is obligated under the Senior Lien Indenture to impose rentals, rates and other charges on the airlines for use of O'Hare that will enable the City to satisfy the Senior Lien Indenture debt service coverage covenants.
The Senior Lien Indenture provides that, in connection with the expiration of the current Airport Use Agreements, beginning on the first Business Day of June 2018, or another date as the City may select and designate in a Certificate filed with the Trustee (the "Transition Date"), certain new Funds and Accounts will be established and the application of moneys in the Revenue Fund will be revised. See "SECURITY FOR THE 2016 SENIOR LIEN BONDS-Flow of Funds-Flow of Funds After the Transition Date," and APPENDLX B ' SUMMARY OF CERTAIN PROVISIONS OF THE SENIOR LI EN INDENTURE-Indenture Funds and Payment of Debt Service-Disbursements from Revenue Fund From and After the Transition Date."

|1010|
There is no provision for acceleration of the maturity of the 2016 Senior Lien Bonds if any default occurs in the payment of the principal of or interest on the 20.16 Senior Lien Bonds or in the performance of any other obligation of the City under the Senior Lien Indenture or if interest on the 2016 Senior Lien Bonds becomes includible in the gross income of the owners thereof for federal income tax purposes.
2016C Senior Lien Bonds. In addition to the Revenues, the 2016C Senior Lien Bonds are also payable through Fiscal Year 2018 from and secured by a pledge of annual payment amounts to be derived from a subordinate pledge of PFC Revenues (as herein defined) including moneys to be withdrawn from the PFC Capital Fund (as herein defined) (the "2016C Pledged PFCs"). With respect to each such Fiscal Year, the amount of 2016C Pledged PFCs will be the greater of (a) the sum of the 2016C Deposit Requirements (as herein defined) for the July 1 and January 1 Deposit Dates (as herein defined) of the Bond Year commencing during that Fiscal Year and (b) one and ten-hundredths times the Net Debt Service with respect to the 2016C Senior Lien Bonds for the Bond Year commencing during such Fiscal Year.

The PFC Indenture (as herein defined) established the PFC Revenue Fund (the "PFC Revenue Fund"), the PFC Bond Fund (the "PFC Bond Fund") and the PFC Capital Fund (the "PFC Capital Fund"). The 2016C Pledged PFCs are subject, however, to: (i) the prior and superior pledge of and lien on the PFC Revenues and the moneys in the PFC Capital Fund as security for the payment of PFC Obligations (as herein defined) secured under the PFC Indenture (as herein defined); (ii) the payments by the City to fund the costs of certain capital projects at the Chicago/Gary International Airport from PFC Revenues pursuant to the Compact between the City and the City of Gary dated April 15, 1995 Relating to the Establishment of the Chicago-Gary Regional Airport Authority (the "Compact"); (iii) the parity pledge of and lien on the PFC Revenues and the moneys in the PFC Capital Fund as security for the payment of the Senior Lien Obligations of the City issued or secured under the (A) Twenty-Seventh Supplemental Indenture, including the outstanding Chicago O'Hare International Airport General Airport Third Lien Revenue Bonds, Series 2008A (the "Series 2008A Bonds"); (B) Thirty-Sixth Supplemental Indenture, including the outstanding Chicago O'Hare International Airport General Airport Third Lien Revenue Bonds, Series 201 OF (the "Series 201 OF Bonds"), and (C) Thirty-Eighth Supplemental Indenture, including the outstanding Chicago O'Hare International Airport General Airport Third Lien Revenue Bonds, Series 201 IA (the "Series 2011A Bonds"); (iv) the City's right to issue additional Senior Lien Obligations that are also secured by PFC Revenues, including moneys to be withdrawn from the PFC Capital Fund, on a parity with the Series 2016C Senior Lien Bonds; and (v) the City's right to issue Subordinated PFC Obligations (as herein defined) that are secured by a pledge of and lien on the PFC Revenues and the moneys in the PFC Capital Fund that is superior to the pledge and lien created by the Fifty-Fourth Supplemental Indenture.

For purposes of this Official Statement, the term "PFC Obligations" refers to all bonds, notes or evidences of indebtedness payable from PFC Revenues and issued by the City at any time under and pursuant to the Master Trust Indenture Securing Chicago O'Hare International Airport Passenger Facility Charge Obligations dated as of January 1, 2008, amending and restating the Master Trust Indenture securing Chicago O'Hare International Airport Second Lien Passenger Facility Charge Obligations dated as of May 15, 2001, as supplemented and amended (the "PFC Indenture"), from the City to The Bank of New York Mellon Trust Company, National Association, as successor to BNY Midwest Trust Company, N.A., as trustee (the "PFC Trustee"), including any obligation of the City under a Qualified PFC Swap Agreement and any obligation incurred by the City to reimburse the issuers of any letters of credit securing one or more Series of PFC Obligations; the term "Subordinated PFC Obligations" refers to all bonds, notes or evidences of indebtedness, so designated and issued by the City payable out of or secured by the pledge of amounts withdrawn from the PFC Revenue Fund, the PFC Bond Fund or the PFC Capital Fund which pledge is junior and subordinate to the pledge for the PFC Obligations; and the term "Airport PFC Obligations" refers to and includes all bonds, notes or other evidences of indebtedness secured by a pledge of PFC Revenues, including PFC Obligations and Subordinated PFC Obligations.
|1010|
Moneys withdrawn from the PFC Capital Fund will be paid to the Trustee and deposited into the 2016C Senior Lien Bond PFC Revenue Deposit Account to satisfy the 2016C Deposit Requirements for the 2016C Senior Lien Bonds for each January 1 and July 1 Deposit Date through Fiscal Year 2018. The City has also agreed that through Fiscal Year 2018, the aggregate sum withdrawn from the PFC Capital Fund and paid to the Trustee for deposit into the 2016C Senior Lien Bond PFC Revenue Deposit Account will be not less than one and ten-hundredths times the Net Debt Service with respect to the 2016C Senior Lien Bonds for the Bond Year commencing during such Fiscal Year.

The "PFC Revenues" consist of all revenue received by the City from the passenger facility
charges imposed by the City at O'Hare pursuant to the PFC Act, the PFC Regulations, the PFC Approvals
—(as-defihed-herein)-and an'Ordinance-adopted-by-the-City-Council ofthe City-on. January.J2, ¦1993(each

O'Hare Modernization Program. The OMP was designed to meet the future development needs at O'Hare and to address flight delays and to increase capacity. The OMP airfield projects (the "OMP Airfield Projects") are changing the airfield from a layout with intersecting runways to a modern parallel runway system. The OMP, which includes the construction of one new runway, the relocation of three existing runways and the extension of two existing runways, is being undertaken in phases. To date, three ofthe four runways have been completed and one ofthe two runway extensions has been completed. All of the completed OMP Airfield Projects have been fully funded, requiring no further General Airport Revenue Bond ("GARB") funding. The only OMP Airfield Projects remaining to be funded and constructed are one runway and one runway extension. For additional information, see "CAPITAL PROGRAMS" and APPENDIX E "REPORT OF THE AIRPORT CONSULTANT."

Capital Improvement Program. The capital improvement program includes projects at O'Hare that address ongoing capital needs. O'Hare regularly updates and adopts a five-year capital improvement program for budget and planning purposes. The current five-year capital improvement program (the "2016-2020 CIP") includes: construction of a multi-modal facility (the "Multi-Modal Facility") which will have a consolidated rental car facility (the "CRCF"), which includes two levels of public parking and an extension of the Airport Transit System (the "ATS"); the construction of a cargo facility in the northeast area of the Airport; the expansion of the airport maintenance center; electrical and mechanical upgrades to the heating and refrigeration plant; ongoing runway and taxiway rehabilitation; and additions and modifications to terminal facilities. For additional information regarding the 2016-2020 CIP and the funding thereof, see "CAPITAL PROGRAMS-OMP Airfield Projects" and APPENDIX E-"REPORT OF THE AIRPORT CONSULTANT-Thc Airport Facilities, Capital Program and 2016 Projects."

Other Recently Announced Capital Projects. The City recently announced a new series of capital projects that are neither directly part ofthe OMP Airfield Projects nor the 2016-2020 CIP, as well as other projects including an expansion ofthe International Terminal and Concourse L in Terminal'3. Additional long-term terminal development and redevelopment options as part of a Terminal Area Plan ("TAP") are being evaluated in coordination with the airline representatives. The TAP is in preliminary planning and discussion phases. In addition to the terminal projects, a redevelopment of the existing terminal hotel and the construction of two new hotels on O'FIare property arc also planned and expected to be completed between 2020 and 2022. The feasibility of a future express rail third-party project connecting O'Hare to the central business district is currently being studied. For additional information on these projects and the funding thereof, see "CAPITAL PROGRAMS-Other Recently Announced Capital Projects" and APPENDIX E- 'REPORT OF THE AIRPORT CONSULTANT."

Security for the 2016 Senior Lien Bonds
General

The 2016 Senior Lien Bonds and the interest thereon are limited obligations of the City payable from and secured by a pledge of the Revenues of O'Hare and certain funds, sub-funds and accounts maintained under the Senior Lien Indenture and do not constitute an indebtedness or a loan of credit of the City within the meaning of any constitutional or statutory limitation, and neither the faith and credit nor the taxing power of the State of Illinois, the City or any other political subdivision of the State of Illinois is pledged to the payment of the principal of, premium, if any, or. interest on the 2016 Senior Lien Bonds. The 2016 Senior Lien Bonds are not payable in any manner from revenues raised by taxation. No property ofthe City (including property located at O'Hare) is pledged as security for the 2016 Senior Lien Bonds.
As described below, the claim ofthe holders ofthe Senior Lien Obligations, including holders of the 2016 Senior Lien Bonds, to the Revenues of O'Hare is a first lien on and pledge of such Revenues and is senior to the claim of any Junior Lien Obligations. The 2016 Senior Lien Bonds arc secured on a parity' basis with the City's Outstanding Senior Lien Obligations. Subject to certain conditions set forth in the Senior Lien Indenture, the City may issue additional Senior Lien Bonds or other Senior Lien Obligations (collectively, the "Additional Senior Lien Bonds") that will be secured on a parity basis with the 2016. Senior Lien Bonds and the City's other Senior Lien Obligations. See "OUTSTANDING INDEBTEDNESS AT O'HARE-Airport Obligations-Issuance of Additional Airport Obligations" and "CAPITAL PROGRAMS."

The application of 2016C Pledged PFCs for the payment of principal and interest on the 2016C Senior Lien Bonds will reduce the amount of principal and interest expense otherwise payable from Airport Fees and Charges payable by the Airline Parties. See "-Flow of TunAs-Purpose and Funding ofthe 2016C Senior Lien PFC Revenue Deposit Account," below.

O'Hare Revenues Must Be Used For Airport Purposes
The Senior Lien Indenture provides that moneys and securities held by the City in the Airport Development Fund and the Airport General Fund may be applied, used and withdrawn by the City for any lawful corporate purpose. Sec "-Flow of Funds" for a description ofthe Airport Development Fund and

Debt Service Reserves

The 2016A Senior Lien Bonds and the 2016B Senior Lien Bonds are Common Reserve Bonds secured by the Common Debt Service Reserve Sub-Fund.
Common Debt Service Reserve Sub-Fund. Pursuant to the Senior Lien Indenture, the Common Debt Service Reserve Sub-Fund is a Dedicated Sub-Fund within the Debt Service Fund which is held and administered by the Trustee in accordance with the terms of the Senior Lien Indenture. The 2016A Senior Lien Bonds, the 2016B Senior Lien Bonds, as well as the Outstanding Senior Lien Bonds, other than the Series 2005C Bonds, the Series 2005D Bonds, the Series 2008A Bonds, the Series 2010D Bonds, the Series 2010F Bonds, the Series 2011A Bonds, the Series 2012A Bonds and the 2016C Senior Lien Bonds (which series of bonds are collectively referred to herein as the "Non-Common Reserve Bonds") arc entitled to the benefit of the Common Debt Service Reserve Sub-Fund (the "Common Reserve Bonds"). Non-Common Reserve Bonds, other than the Series 2005C Bonds and the Series 2005D Bonds, are each secured by a separate debt service reserve account established under the respective Supplemental Indenture authorizing their issuance. These individual debt service reserve accounts do not secure and arc not available for payment of debt service on the Common Reserve Bonds, and the Common Debt Service Reserve Sub-Fund does not secure and is not available for payment ofthe Non-Common Reserve Bonds. The Series 2005C Bonds and the Series 2005D Bonds are not secured by a reserve hind.



21

The "Reserve Requirement" for the Common Debt Service Reserve Sub-Fund is an amount equal to the maximum'amount of Principal Installments and interest payable on the Common Reserve Bonds in the current or any succeeding Bond' Year; provided, however, that if upon the issuance of a series of Common Reserve Bonds such amount would require'that moneys be paid into the Common Debt Service Reserve Sub-Fund from the proceeds of such Common Reserve Bonds in an amount in excess of the maximum amount permitted under the Code, the Reserve Requirement shall be the sum of (a) the Reserve Requirement immediately preceding the issuance of such Common Reserve Bonds, and (b) the maximum amount permitted under the Code to be deposited from the proceeds of such Common Reserve Bonds, as certified by the Chief Financial Officer.
Additional Senior Lien Bonds issued by the City in the future pursuant to the Senior Lien Indenture may,. but.need not,.be designated as entitled
The Reserve Requirement for the Common Debt Service Reserve Sub-Fund may be satisfied by
the deposit with the Trustee of (i) cash, (ii) one Or more Qualified Credit Instruments, (iii) Qualified
Investments, or (iv) a combination thereof: - ¦ ,

The Senior Lien Indenture i provides, and the City covenants in the applicable Supplemental Indenture with respect to the 2016A Senior Lien Bonds and 2016B-Senior Lieri Bonds^ that (i) the City will maintain the Common Debt Service Reserve Sub-Fund in an amount equal to the Reserve Requirement, (ii) moneys held therein will be held and disbursed for the benefit.of all Common Reserve Bonds and such. rrioneys are* pledged'and assigned-for that purpose, and (iii) all Common Reserve Bonds are.on'a parity and.rank .equally,-without'preference,-priorityior.distinction. If oniany .valuation date under the Senior Lien Indenture the amount on deposit in the Common .Debt. Service Reserve. Sub-Fund is more than the Reserve Requirement, unless otherwise directed by a Certificate of the City to be withdrawn and deposited iritrust'topay orprovide for the payment of Senior-Lien> Obligations, the amount of such excess shall be transferred-to the Trustee for deposit into the Revenue Fund, provided, However, that immediately after such withdrawal, the amount on deposit in:the Common Debt Service Reserve Sub-Fund equals or exceeds the Reserve Requirement. ¦

If at any time the Common Debt Service Reserve Sub-Fund holds both Qualified Credit Instruments and Qualified Investments, the Qualified Investments shall be liquidated and the proceeds applied for the purposes for which Common Debt Service Reserve Sub-Fund moneys may be applied under the Senior Lien Indenture prior to any draw being made on the Qualified Credit Instrument. If the Common Debt Service Reserve Sub-Fund holds Qualified Credit Instruments issued by more than one issuer, draws shall be made under such credit instruments on a pro rata basis to the extent of available funds.

Deficiencies in the Common Debt Service Reserve Sub-Fund are required to be satisfied from Revenues. Amounts deposited in the Common Debt Service Reserve Sub-Fund shall be applied first to reimburse the Qualified Credit Provider and thereby reinstate the Qualified Credit Instrument and next to make deposits into the Common Debt Service Reserve Sub-Fund. The Common Debt Service Reserve Sub-Fund will be applicable only to the Common Reserve Bonds and will not be available to pay debt service on any other Senior Lien Obligations. See "Payment of Debt Service on the 2016 Senior Lien Bonds" above and APPENDIX B ' SUMMARY OF CERTAIN PROVISIONS OF THE SENIOR LIEN INDENTURE-Indenture Funds and Payment of Debt Service:"

Subsequent to the issuance ofthe 20T6A Senior Lien Bonds and the 2016B Senior Lien Bonds, the Reserve Requirement for the Common Reserve Bonds will be $424,667,322.50, which will be fully funded with cash and Qualified Investments on deposit in satisfaction of the requirements ofthe Senior Lien Indenture. In addition to the cash and Qualified Investments on deposit, various Qualified Credit

Instruments remain on deposit in the Common Debt Service Reserve Sub-Fund. As a result of the widespread losses in the mortgage market and overall credit market challenges, among others, Qualified Credit Providers may experience claims and/or reductions in capital such that their capital resources may no longer be sufficient at their respective rating levels to meet their ongoing additional capital needs and/or to respond to claims, including claims under the Qualified Credit Instruments. In the event ofthe financial distress of any Qualified Credit Provider that has provided a Qualified Credit Instrument on deposit in the Common Debt Service Reserve Sub-Fund, the City is under no obligation to replace the applicable Qualified Credit Instrument with cash or another Qualified Credit Instrument so long as the Common Debt Service Reserve Sub-Fund remains fully funded with cash and Qualified Investments on deposit in satisfaction ofthe requirements of the Senior Lien Indenture. Except as may be required by the Undertaking described below under "SECONDARY MARKET DISCLOSURE," neither the City nor the Underwriters undertakes responsibility to bring to the attention of the owners of the 2016 Senior Lien Bonds any information regarding the financial condition of any Qualified Credit Provider or to take any action in connection therewith.

2016C Senior Lien Debt Service Reserve Account. The Reserve Requirement for the 2016C Senior Lien Bonds will be the maximum amount of principal of and interest on the 2016C Senior Lien Bonds payable in the current or any future Bond Year. In the Fifty-Fourth Supplemental Indenture, the City covenants that the City will maintain the 2016C Senior Lien Debt Service Reserve Account in an amount equal to the Reserve Requirement, which requirement may be satisfied with (i) one or more Qualified Reserve Account Credit Instruments, (ii) Qualified'Investments, or (iii) a combination thereof. Upon issuance of the 2016C Senior Lien Bonds, to satisfy the Reserve Requirement, the City intends to deposit into the 2016C Senior Lien-Debt Service Reserve Account (i) a portion of the proceeds from-the sale of the 2016C Senior Lien Bonds and (ii) amounts on deposit in the debt service reserve accounts for the Series 2008A Bonds refunded by the 2016C Senior Lien Bonds.

Covenants Against Lien on Revenues: .

The City covenants in the Senior Lien Indenture that it will not issue any indebtedness, other than Senior Lien Obligations, secured by the pledge of Revenues. The City also covenants not to create or cause to be created any lien or charge on Revenues, or on any other amounts pledged for the benefit of owners of the Senior Lien Obligations, including the 2016 Senior Lien Bonds, other than the pledge of Revenues contained in the Senior Lien Indenture.
Notwithstanding the covenants described in the prior paragraph, the City has the right to issue debt payable from or secured by a pledge of the Revenues to be derived on and after the discharge and satisfaction of all Senior Lien Obligations-and to issue debt payable from, or secured by, a pledge of amounts to be withdrawn from the Junior Lien Obligation Debt Service Fund so long as such pledge is expressly junior and subordinate to the pledge of Revenues to the payment of Senior Lien Obligations.
Issuance of Additional Senior Lien Bonds

Additional Senior Lien Bonds may be issued upon the satisfaction of certain conditions as set forth in the Senior Lien Indenture. These conditions include delivery to Trustee of:

(i) a Certificate of an Independent Accountant or a Certificate of the City, in either case stating that Revenues and Other Available Moneys in the most recent completed Fiscal Year for which audited financial statements have been prepared satisfied the first covenant described


24

under "-Debt Service Coverage Covenants" above, assuming for such purpose that Aggregate Debt Service for the Bond Year commencing during such Fiscal Year includes the maximum Annual Debt Service on all Outstanding Senior Lien Obligations and the Series of Senior Lien Obligations proposed to be issued (disregarding any Airport Obligations that have been paid or discharged or will be paid or discharged immediately after the issuance of the Senior Lien Obligations proposed to be issued); or
(ii) a Certificate of an Independent Airport Consultant or a Certificate ofthe City, in either case stating that, based upon reasonable assumptions set forth in the Certificate, Revenues and Other Available Moneys are projected to be not less than that required to satisfy the first covenant described under "-Debt Service Coverage Covenants" above (disregarding any Airport Obligations that have been paid or discharged or will be paid or discharged immediately after the issuance of the Senior Lien Obligations proposed to be issued) for each of the next three Fiscal Years following the issuance of the Senior Lien Obligations or, if later, for each Fiscal Year from the issuance ofthe Senior Lien Obligations through the two Fiscal Years immediately following completion of the project or projects financed by the Senior Lien Obligations.
For the purpose of computing Revenues under either clause (i) or (ii) above, there must be taken
into account (x) any reduction in the rate of any PFCs, and (y) any increase in the rate of any PFCs
authorized by legislation if the City has taken all action required to impose those increased charges at
O'Hare pursuant to such legislation. For the purpose of computing Revenues and Other Available
Moneys under clause (ii) above, Other Available Moneys shall be projected only to the extent they have
been (x) paid over -to the Trustee and deposited in the Revenue Fund, or (y) irrevocably-pledged to the

The City may issue Refunding Bonds and Completion Bonds (both as defined in the Senior Lien Indenture) either by satisfying the debt service coverage requirement described above, or by satisfying the applicable requirements described in APPENDIX B "SUMMARY OF CERTAIN PROVISIONS OF THE SENIOR LIEN INDENTURE-Refunding Bonds" and "-Completion Bonds." After the issuance ofthe Senior Lien Bonds, the City plans to issue Additional Airport Obligations to fund the 2016 Airport Projects (as herein defined). Sec "PLAN OF FINANCE - 2016 Airport Projects."

Airport Use Agreements
Airport Use Agreements. Moneys deposited by the City in accordance with the Senior Lien Indenture include rentals, fees and charges imposed upon the Airline Parties under the several Amended and Restated Airport Use Agreements and Terminal Facilities Leases (collectively, the "Airport Use Agreements") between the City and the Airline Parties (as herein defined). The Airport Use Agreements provide that the aggregate of all rentals, fees and charges to be paid by the Airline Parties shall be sufficient to pay for the net cost of operating, maintaining and developing O'Hare (excluding the Land Support Area), including the satisfaction of all of the City's obligations to make deposits and payments under the Senior Lien Indenture and any other ordinance or resolution authorizing Airport Obligations in accordance with the Airport Use Agreements.

The City has entered into Airport Use Agreements with the airlines identified as signatories to the Airport Use Agreements in "AIR TRAFFIC ACTIVITY AT O'HARE-Airlines Providing Service at O'Hare." Those airlines, together with any additional airline that executes an agreement with the City substantially the same as the Airport Use Agreements, are referred to as the "Airline Parties." Sec "AIR TRAFFIC ACTIVITY AT O'HARE-Airlines Providing Service at O'Hare" and "CERTAIN INVESTMENT CONSIDERATIONS."

Flic City was not required to obtain funding approvals of the Airline Parlies for the issuance of the 2016 Senior Lien Bonds.


25

Expiration of Airport Use Agreements. The expiration date of each of the Airport Use Agreements is May 11, 2018. A significant portion of the debt service on the 2016 Senior Lien Bonds and the Outstanding Senior Lien Bonds becomes due after such date. Upon the expiration of the Airport Use Agreements, the Gity may extend such agreements, enter into new agreements with the airlines, or impose rates and charges upon the airlines by City ordinance consistent with the requirements of federal law. Regardless of which of these options is pursued, the City has covenanted in the Senior Lien Indenture (which extends beyond the expiration ofthe Airport Use Agreements) to establish rentals, rates and other charges for the use and operation of O'Hare such that Revenues (including rentals, fees and charges imposed on the airlines), together with certain other moneys deposited with the Trustee, are sufficient to pay the Operation and Maintenance Expenses at O'Hare arid to satisfy the debt service coverage covenants contained'in the'Senior Lieri Indenture. See ' "-Debt Service Coverage Covenants" above! Thus, while it is not possible' to predict whether any airline will be contractually'obligated to make payments, including, among other things, for debt service on the 2016 Senior Lien Bonds, the Outstanding Senior Lien Bonds or any other Senior Lien Bonds after the expiration date of the Airport Use Agreements in 2018, the City is obligated under-1 the Senior Lien Indenture to impose' fees and charges on the airlines for use of O'Hare that will enable' the City to satisfy the Senior Lien Indenture debt service coverage covenants.

Nonpayment of Rentals, Fee's and Charges. The Airport Use Agreements provide that if an Airline Party defaults on; the'payment of-its rentals; fees or :cha'rges, and if the City--has: undertaken appropriate'collection efforts arid has exhausted certain^ other specific funds available'under the Airport Use Agreements to pay the unpaid rentals, fees or charges, the City then is entitled to include the unpaid rentals, fees or charges in the landing fees payable by the other; non-defaulting Airline Parties. See APPENDIX C-'SUMMARY OF CERTAIN PROVISIONS OF THE AIRPORT USE AGREEMENTS."

Issuance of Additional Senior Lien Obligations Secured by Pledged PFCs
The Fifty-Fourth Supplemental Indenture'provides that 'the Pledged PFCs pledged to the payment of principal and interest on the 2016C Senior Lien Bonds are subject to the'City's right to issue additional Airport Obligations that are also secured by'Pledged PFCs on ^parity with the 2016C Senior Lien Bonds. Certain Series of the 2016 New Money Bonds shall be secured by Pledged PFCs on parity with the 2016C Senior Lien Bonds.

Within the first six months of 2017, the City plans to issue the 2017 PFC Bonds to pay the costs of certain projects included in the OMP, fund the related reserve requirements, refund certain outstanding PFC Obligations and pay the related costs of issuance of the 2017 PFC Bonds, as more fully described under "PLAN OF FINANCE" herein. The 2017 PFC Bonds shall be secured solely by PFCs and are senior to the pledge of PFCs for Senior Lien Obligations. If issued, the City will offer the 2017 PFC Bonds pursuant to a separate official statement.'

Proposed Amendment to the Senior Lien Indenture
The City has proposed an amendment (the "2010 Amendment") to the Senior Lien Indenture that would remove the restrictions described under "Restrictions on Sales or Transfer of Airport" in APPENDIX B. The 2010 Amendment will not take effect unless and until (among other things) the 2010 Amendment is consented to by the Owners of more than 50% in principal amount of the then Outstanding Senior Lien Obligations and the City determines to present such amendment to the Trustee. Pursuant to the 2016 Supplemental Indentures authorizing each Series ofthe 2016 Senior Lien Bonds, the Owners of the 2016 Senior Lien Bonds shall be deemed to have consented to the 2010 Amendment by purchasing such 2016 Senior Lien Bonds. Such consent of any Owner may be revoked in writing as provided in the Senior Lien Indenture. Currently and continuing after the issuance of the 2016 Senior Lien Bonds, Owners of the required percentage of the Outstanding Senior Lien Obligations have consented to the


26

20JO Amendment and the City thus may elect to implement the 2010 Amendment by presenting it to the Trustee for execution.
Remedies

There is no provision for the acceleration of the maturity of the 2016 Senior Lien Bonds if any default occurs in the performance of any other obligation of the City under the Senior Lien Indenture, or if interest on the 2016 Senior Lien Bonds becomes includible in the gross income of the Owners thereof for federal income tax purposes.

Plan of Finance
General
The City is issuing the 2016 Senior Lien Bonds to: (i) refund certain outstanding Airport Obligations; (ii) fund the related reserve requirements for the 2016 Senior Lien Bonds; and (iii) pay costs and expenses incidental thereto and to the issuance of the 2016 Senior Lien Bonds. The 2016 Senior Lien Bonds are payable from and secured by a pledge of the Revenues and certain Funds and Accounts held under the Senior Lien Indenture.

Refunding Plan
The City intends to redeem the Refunded Bonds with proceeds of the Senior Lien Bonds. The table in APPENDIX H - "BONDS TO BE REFUNDED" sets forth the series designation, maturities, principal amounts, interest rates, and redemption dates for the Refunded Bonds. On the date of issuance and delivery of the 2016 Senior Lien Bonds the City will give the Trustee irrevocable instructions to call the Refunded Bonds on their applicable redemption dates. Notices of the call for redemption of the Refunded Bonds will be given by the Trustee in the manner required by the Senior Lien Indenture and the applicable Supplemental Indentures.
To provide for the refunding of the Refunded Bonds, certain proceeds of the 2016 Senior Lien Bonds and other available funds will be deposited in an escrow account (the."Escrow Account") pursuant to the provisions of a Refunding Escrow Agreement (the "Escrow Agreement"), dated as of December 1, 2016, between the City and U.S. Bank National Association, as trustee under the Senior Lien Indenture, to provide for the defeasance of the Refunded Bonds and their redemption at par plus accrued interest to the date of redemption. The moneys so deposited in the Escrow Account will be invested in "Federal Obligations" pursuant to Section 1101 of the Senior Lien Indenture, and the principal of and the interest on such Federal Obligations (without reinvestment) shall be sufficient to pay when due the interest on. the Refunded Bonds to and including the applicable redemption date thereof and the redemption price of each Refunded Bond on its redemption date.

Other Commercial Service Airports Serving the Chicago Region
Midway. In addition to O'Hare, Midway is owned by the City and operated through the CDA.
Midway, located 15 miles south of O'Hare arid nine miles southwest of the .central .business district of the
City, also provides scheduled commercial passenger service. 'Based upon CDA management records,
total enplaned passengers at Midway were 11,003,697 for 201'5 and 10,497,727 for 2014. As of August
2016, Midway provided nonstop service to 75 markets (nine of which are international destinations) with
a total of 272 daily nonstop flights whereas O'Hare has approximately 1,097 daily nonstop flights to 231
markets (64 of which are international destinations). In 2015, Midway had 4,227,590 connecting
cripTariemerits and 6,890,633originating"en^ represented approximately
25.5 percent of Chicago originating passenger traffic and approximately 18.8 percent of Chicago connecting passenger traffic, whereas O'Hare's originating and connecting percentages of Chicago passenger traffic for 2015 were approximately 74.5 percent and 82.2 percent, respectively.
O'Hare and Midway are operated as separate and distinct enterprises for financial purposes and the 2016 Senior Lien Bonds are not secured by any revenues generated, or property located, at Midway.
General Mitchell International Airport. The nearest commercial service airport outside the
Chicago Region is General Mitchell International Airport ("Mitchell"), located approximately 70 miles
north of O'Hare. Mitchell serves the commercial air service needs of Milwaukee, southeast Wisconsin,
and portions of northern Illinois. Total enplaned passengers at Mitchell were approximately 3.3 million
in each of the years 2015 and'2014. Although Mitchell-isi in,close proximity to O'Hare (their overlapping
service areas include three counties in the northem/Ghieag6':R'egi6h area, which represent approximately
12 percent of the population in the Chicago Region), the higher-frequency nonstop service to top O&D
markets from O'Hare attracts a greater portion qfpraffi^ Wisconsin to
O'Hare. On average in 2015, Mitchell had-approximately 107;daily nonstop flights to'38 markets (5 of
which were international). '• .««--.* „,".....
Gary/Chicago International Airport. Gary/Chicago International Airport, which is owned by the City of Gary, Indiana, is also located in the ChicagoRegion.': Currently, no commercial passenger service is provided at Gary/Chicago International Airport.
Existing Airport Facilities
O'Hare currently has eight active runways, which allow for operations in good and poor weather conditions. A network of aircraft taxiways, aprons and hold areas supports the runways. The runways range from 7,500 feet to 13,001 feet. All runways have electronic and other navigational aids that permit aircraft landings in most weather conditions. For more information regarding the existing airfield facilities at O'Hare, see "The Airport Facilities, Capital Program, and 2016 Projects-Airport Facilities-Airfield" in APPENDIX E "REPORT OF THE AIRPORT CONSULTANT."
The airlines serving O'Hare operate out of four terminal buildings. Three terminal buildings, having a total of 170 aircraft gates, serve domestic flights and certain international departures. A fourth terminal building, the International Terminal, with 19 aircraft gates and four hardstand positions, serves the remaining international departures and all international arrivals requiring customs clearance. The ATS serves the three domestic terminals, the International Terminal and the remote long-term parking areas. For more information regarding the existing terminal facilities at O'Hare, see APPENDIX E-"REPORT OF THE AIRPORT CONSULTANT-The Airport Facilities, Capital Development Program, and 2015 Projects-Airport Facilities-Terminal Area."

Recent O'Hare Operations
For over '40 years, O'Hare has been and continues to be one of the principal components in the
national airspace system, providing riot only the primary origin and destination, service to the third largest
metropolitan area in the United States, but also serving as an important connecting: bub for two of the
world's four largest air-carriers (in terms of revenue passenger miles)' - United Airlines and American
Airlines. Preliminary statistics, from ACT indicate that for 2015 O'Hare ranked second worldwide and in
the United States in total aircraft operations with 875,136 takeoffs and landings, and seventh worldwide
and third in the United States in total passengers. O'Hare served approximately 38;38; million enplaned
and deplaned passengers in 2015, an increase of 9.9% from the previous year. Through the first seven
months' of 20.16,' passenger activity at O'Hare' has; increased: 2-.7% 'frbrir the record volume over the same
period in 2015. •' ¦¦.-¦<¦¦• .w-.' ¦
As of August 2016, nonstop service was provided '< from O'Hare to each of 0:1 fare's top 50 domestic O&D markets. Scheduled service in August 2016 included an average of 1,233 nonstop departures from O'Hare, including 1,108 domestic departures and 128 international departures:

These decreases'in total enplaned passengers in 2009 (as compared to prior years), which were similar: to those experienced nationally,- were primarily due to cutbacks in capacity by the airlines in response to record high fuel costs and a nationwide economic recession, which impacted demand for air travel. From 2010 through 2013;'0'Hare experienced relatively stable activity with approximately 33 million in enplaned passengers annually. Enplaned passenger activity for 2015 rose 9.9% over 2014. For the first seven months of 2016 passenger activity increased 2.7% from the same period in 2015 lo approximately 27.3 million enplaned passengers:
As set forth in the following table, O'Hare supports substantial international service. Between 2006 and 2015, the percent of international enplaned passengers ranged from 14.38 to 16.18 percent of the total enplaned passengers.

Enplaned passenger traffic at O'Hare can be divided into two primary components: O&D and connecting. O&D enplaned passengers consist of two groups. The first group includes those travelers whose residence and/or place of employment are in the Chicago Region and surrounding communities and whose air trips originate at O'Hare. The second group includes travelers who are not residents of or employed within the Chicago Region and surrounding communities, but who visit for business, personal or pleasure-related activity. Connecting passengers include those passengers traveling from a destination outside the Chicago Region to a destination outside the Chicago Region, who board one aircraft at O'Hare after having arrived on another aircraft at O'Hare. The number of connecting enplaned passengers at O'Hare reflects airline operating decisions, which are in part dictated by the size ofthe local air passenger market, the profitability of O'Hare to the airlines, and the geographic location of O'Hare relative to heavily traveled air routes.
The following table shows total enplaned passengers, total originating enplaned passengers and total connecting enplaned passengers at O'Hare for a 10-year period from 2006 through 2015. As shown, O'Hare has a strong O&D market with the percent of originating passengers ranging from 47.8% to 52.4% of total enplaned passengers over the 10-year period.

Aircraft Operations
The following table shows total aircraft operations at O'Hare for the 10-year period 2006 through 2015. From 2006 through 2009, the number of aircraft operations steadily decreased, to 827,899. After increasing to 882,617 in 2010, the number of aircraft operations decreased slightly to 878,108 in 2012, and increased to 883,287 in 2013 with a slight decrease to 881,933 in 2014. Prior to 2015, United and American shifted domestic passenger service from their mainline service to their regional affiliates, shown by the increase in regional affiliates over the period. Mainline aircraft operations increased from 267^044 in 2014 to 306,670 in 2015. The national economic recession and the recent trend of operating capacity with larger aircraft were the primary cause of total operations at O'Hare decreasing from 958,643 in 2006 to 875,136 in 2015.

(1) Pension Expense is included in 2015 as a separate category due to implementation of Governmental Accounting Standards Board Statement No. 68, Accounting and Financial Reporting for Pensions - An Amendment of GASB Statement No. 27 ("GASB 68"). GASB 68 requires inclusion of certain expenses that are not payable in that year but required to be recorded in the City's Airport financial statements. Prior to GASB 68 (from 2011 through 2014 in the above table), Salaries and Wages included the Pension Expense due and payable in each year.

DrscussiON of Financial Opera tions
The "Historical Operating Results" tabic above summarizes O'Hare's audited financial results for the years 2011 through 2015. Operating revenues in the table are comprised of landing fees, terminal area rental/use charges, other rentals/fueling system fees and concessions. Operation and Maintenance Expenses are comprised of salaries and wages, repairs and maintenance, energy, materials and supplies, engineering and other professional services and other operating costs which include insurance premiums, equipment rentals, vehicles and various miscellaneous costs.



41

The City charges the Airline Parties based on a projection of, and recognizes revenues from the Airline Parties only to the extent required to fund, the net airline requirement (equal to Operation and Maintenance Expenses, net debt service requirements and fund deposit requirements less non-airline revenues and credits). Accordingly, landing fees and terminal area rental/use charges increased $3.6 million in 2015 compared to 2014, due to an increased net airline requirement, driven by an increase in cash Operation and Maintenance Expenses and an increase in net debt service requirements, which were not completely offset by increased non-airline revenues.

The increase in total Operation and Maintenance Expenses before depreciation and amortization of "approximately $310 million-from 201'4^
from the implementation of GASB 68 and increases in salaries and wages.
Ofthe $339.5 million of Pension Expense recorded for 2015, $25.8 million is the portion ofthe , City's pension contribution payable in 2015 to the Retirement Funds (as herein defined) and allocable to O'Hare. The remaining portion. of the Pension Expense for 2015 ($313.7 million) is recognized on the income statement of O'Hare for 2015 pursuant to GASB 68 but is not due and payable by the City during 2015; accordingly, that portion is not included in Operating Expenses for purposes of calculation of the debt service coverage ratios.
The increase in non-airline revenues and reimbursements of $3 million from 2014 to 2015 was primarily due to increases in auto parking, restaurants and auto rentals of $3.9 million, $1.3 million," and $1.3 million, respectively.
Cash Balances
As of December 31, 2015, O'Harc's unrestricted cash and investments balance in the O'Hare Land Support Fund, Revenue Fund and O&M Fund was $143.5' million and its restricted cash and investments balance was $2,498 billion compared to December 31, 2014 balances of $99.6 million in the O'Hare Land Support Fund, Revenue Fund and O&M Fund and $2,463 billion in restricted cash and investments. The December 31, 2015 restricted cash and investments balance was comprised of construction funds of $650.5 million; $79.6 million of capitalized interest, $1,105 billion from debt service reserve and debt service funds, $133.8 operation and maintenance reserve, $93.9 million customer facility charge funds, $342.5 million in the Airport Development Fund, $42.6 million in other funds, and $126.3 in the passenger facility fund. The restricted cash and investments balance includes approximately $650.5 million in construction funds that the City expects to spend through 2018.

Insurance . .

The City maintains property and liability insurance coverage for both O'Hare and Midway and allocates the cost of the premiums between the two airports. The City's property and liability premiums for both O'Hare and Midway are approximately $9 million per year. The property coverage renewed on December 31, 2015 with a limit of $3.5 billion total for both airports and includes terrorism, and the liability coverage renewed on May 15, 2016 with a limit of $1 billion total for both airports and includes $750 million in war and terrorism liability coverage.
Pension Costs
Determination of Pension Contributions
Each O'Hare employee participates in one of four single-employer defined-benefit pension plans for City employees: the Municipal Employees' Annuity and Benefit Fund of Chicago (the "MEABF"),

42

the Laborers' and Retirement Board Employees' Annuity and Benefit Fund of Chicago (the "LABF," and together with the MEABF, the "Municipal and Laborers' Funds"), the Policemen's Annuity and Benefit Fund (the "PABF"), or the Firemen's Annuity and Benefit Fund (the "FABF," and together with the PABF, the "Public Safety Funds," which, together with the Municipal and Laborer's Fund, are referred to herein as the "Retirement Funds"). For additional information on the O'Hare's portion of the net pension liability to the Retirement Funds, see Appendix D-"AUDITED FINANCIAL STATEMENTS- NOTES 7 and 8." The Report of the Airport Consultant in Appendix E sets forth projected Personnel Expenses which incorporate O'Hare's projected contributions to the Retirement Funds from 2016 through 2025.
Members of each Retirement Fund are eligible (individually, an "Eligible Member," and collectively, "Eligible Members") for an annual annuity payment (the "Annuity Benefits") if they meet certain age, years of service and prior service credit requirements (the "Eligibility Factors"). Benefits to each Eligible Member are statutorily established based on a combination of the Eligibility Factors and the Eligible Member's average annual salary for certain years prior to retirement (the "Annuity Factors").
Annuity Benefits for each of the Retirement Funds are funded from three sources: (i) contributions from the City (the "City Contributions") which are funded from the proceeds of a property tax levy on all taxable property located within the City or other available funds, including payments from O'Hare on behalf of the O'Hare employees, (ii) contributions from Eligible Members (the "Employee Contributions," and together with the City Contributions, the "Contributions"), and (iii) investment returns, O'Hare has historically contributed its pro rata share of City Contributions to the Retirement Systems (the "O'Hare Portion") based on the Annuity Factors for the number of O'Hare employees who are Eligible Members.
The City Contributions and Employee Contributions are each established by the Illinois Pension Code (the "Pension Code"). Except as described below under "-Public Safety Funds," the Contributions required under the Pension Code do not relate to, and in recent years have been substantially less than, the contribution amounts that would have been required if the Retirement Funds were funded based on actuarial determinations of the contribution amounts necessary to fully fund the Annuity Benefits to Eligible Members of each Retirement Fund over an extended period. See "CERTAIN INVESTMENT CONSIDERATIONS-Financial Condition of the City and Other Overlapping Governmental Bodies" herein. In an effort to improve the funded status ofthe Public Safety Funds, the Illinois General Assembly passed Public Act 96-1495 ("Act 1495"), which modified provisions of the Pension Code with respect to PABF and FABF.
The City's proposed Fiscal Year 2017 budget includes the following contributions to the Retirement Funds (as indicated by total annual contribution and O'Hare proportional share): (i) $267 million for MEABF, of which $18 million, or less than 7 percent, is O'Hare's proportional share; (ii) $36 million for LABF, of which $2,275 million, or 6.4 percent, is O'Hare's proportional share; and (iii) $727 million for FABF and P ABF, of which $ 18.3 million, or 2.5 percent, is O'Hare's proportional share.

Public Safety Funds
The Pension Code establishes the Employee Contributions to PABF at 9.0 percent of the salary of each employee on an annual basis and Employee Contributions to FABF at 9.125 percent ofthe salary of each employee on an annual basis and establishes Annuity Benefits for Eligible Members of the Public Safety Funds hired prior to January 1, 2011 based on the Annuity Factors, subject to 3.0 percent automatic annual increases after each member's first full year of retirement. Prior to the effectiveness of Act 1495, the Pension Code established the City Contribution to PABF at an amount based upon a fixed multiplier of 2.00 times the annual employee contributions to PABF and the City Contribution to FABF at an amount based upon a fixed multiplier of 2.26 times the employee contributions to FABF.

43

Act 1495 provided for the Gity to contribute the actuarially determined amounts necessary to achieve a 90 percent funded ratio in the Public Safety Funds by 2040, but made no changes to the Annuity Benefits for Eligible Employees hired before 'January 1, 2011 and established Annuity Benefits for Eligible Members hired on or:after January 1, 2011 based'on the Annuity Factors; but; with theiaverage annual salary capped at a certain amount, and the annual increases to< the Annuity Benefits tied to the lesser of 3.0 percent or the consumer price index. Additionally, Act 1495 reduced a survivor's Annuity Benefit equal to 2/3: of the Annuity Benefits that the deceased Eligible Member was receiving at the time of his or her death for Eligible Members hired on or after January 1, 201:1
Beginning'' with' mer cbntributi'bn: to ;be: niade:-"t6 r the"' Retirement Funds in 2016, the City's contributions ito PABF and FABF ;will be determined pursuant to P.A. 99-506("Act'506") (which modified the funding approach, for unfunded liabilities set forth in Act 1495), rather than the multiplier funding formula. Act 506 (i) extends the period by which the unfunded liabilities of the Public Safety Funds are amortized, on a leveh percentage of payroll basis, to a 90 percent funded ratio from" 2040 to 2055 and (ii) institutes a phase-in period during 2016-2020 to allow for a more gradual increase in the City Contributions to the Public Safety Funds than originally required by Act 1495;
Municipal and Laborer's Funds
The current Pension Code establishes Annuity Benefits for Eligible Members of the Municipal and Laborers'Funds hired prior to January. 1, 2011 based on the Annuity Factors, subject;to 3 percent automatic annual increases: after the members' first, full year of retirement and Annuity Benefits for Eligible Members hired on or after January 1, 2011 based on the Annuity Factors, but.with the; average annual salary capped at a certain amount, and the annual increases to the Annuity Benefits are tied to the consumer price index.' Furthers the Pension Code establishes the Employee Contribution at 8.5 percent of the*salary-"of 'each cmployee»'6ii:"an:annual basis* and; the Gity;Gbntributiori is established !ati anramdunt' based on a fixed multiplier of 1.25 times the annual employee*contributions for:the MEABF and L00 for the LABF. Without significantly higher contributions or investment returns, the'LABF and the MEABF are currently estimated to become insolvent in'2025 and'2027; respectively. -
• On May 23, 2016, the City announced an agreement-in principle with unions' for employees participating in LABF (the "LABF Plan") pursuant-to which the:City would begin contributing to LABF on an actuarial basis and certain employees participating in LABF would contribute an increased percentage of their salaries to LABF. Similarly, on August 3, 2016, the City announced an agreement in principle with unions for employees participating in MEABF (the "MEABF Plan" and, together with the LABF Plan, the "Stabilization Plans") pursuant to which the City would begin contributing to MEABF on an actuarial basis and certain employees participating in MEABF would contribute an increased percentage of their salaries to MEABF.
Pursuant to the Stabilization Plans, Eligible Members of the Municipal and: Laborers' Funds hired on or after January 1, 2017 ("New Members") would contribute an additional three percent of their salaries to their respective Retirement Funds and would be eligible for benefits at age 65 (as opposed to age 67 for Eligible Members hired between January 1, 2011 and January 1, 2017 ("Tier II Members")). In addition, Tier II Members ofthe Municipal and Laborers' Funds would be eligible to receive benefits at age 65 provided that such Tier 11 Members agree to contribute an additional three percent of their salaries to their respective Retirement Funds.
The Stabilization Plans further provide for the City to contribute the actuarially determined amounts required to achieve a 90 percent funded ratio in the Municipal and Laborers' Funds by; 2057, following a phase-in of certain increased City Contributions ending in 2022. The City expects that legislation will be introduced in the Illinois General Assembly in the fall of 2016 to amend the Pension

44

Code to incorporate the provisions of the Stabilization Plans, and the City intends to support the adoption of such legislation. The City makes no prediction as to whether any such amendments will become law. The City intends to continue to make City Contributions to the Municipal and Laborers' Funds in accordance with the Pension Code in effect when such City Contributions are payable.

Issuance of Additional Airport Obligations. Subject to certain conditions set forth in the Senior Lien Indenture, the City may also in the future issue Additional Senior Lien Bonds or incur other Senior Lien Obligations that will be secured on a parity basis with the 2016 Senior Lien Bonds and the Outstanding Senior Lien Bonds. The 2016 New Money Bonds are Additional Senior Lien Bonds expected to be issued in the fourth quarter of 2016 and will be used to fund the 2016 Airport Projects. See "SECURITY FOR THE 2016 SENIOR LIEN BONDS-Issuance of Additional Senior Lien Bonds" and "CAPITAL PROGRAMS."
The City may issue, from time to time, additional Airport Obligations to fund additional capital projects under the CIP and to fund certain runway projects, all as described under "CAPITAL PROGRAMS." Such additional Airport Obligations may include, without limitation, Senior Lien Bonds. Issuance of any such Senior Lien Bonds would require compliance with the requirements of the Senior Lien Indenture for the issuance of additional debt.
Obligations Subordinate to Senior Lien Bonds. As described under "SECURITY FOR THE 2016 SENIOR LIEN BONDS-Covenants Against Lien on Revenues," the City has the right, at any time, to issue debt payable or secured by amounts to be withdrawn from the Junior Lien Obligation Debt Service Fund so long as such pledge is expressly junior and subordinate to the pledge of Revenues to the payment of Senior Lien Obligations. Indebtedness of the type described in the preceding sentence can be issued without limit as to nature or amount.
The City previously authorized the issuance of Chicago O'Hare International Airport Commercial Paper Notes (the "CP Notes") and Chicago O'Hare International Airport Credit Agreement Notes (the "Credit Agreement Notes"), respectively, in a combined aggregate principal amount outstanding at any one time of up to $1 billion. Pursuant to this authority, the City recently established a $420 million CP Notes program and intends to establish a $180 million program for Credit Agreement Notes. The CP Notes and the Credit Agreement Notes (if and when issued) will be Junior Lien Obligations and subordinate to the 2016 Senior Lien Bonds and all other Senior Lien Obligations with respect to their claim on Revenues. As of the date of this Official Statement, there are no outstanding CP Notes or Credit Agreement Notes.

Letter of Credit Facilities Securing Indebtedness at O'Hare
The City has issued from time to time certain variable rate bonds and notes that are supported by letter of credit facilities provided by banks for the payment of debt service and/or tender prices for such obligations. The City is obligated to reimburse the banks for any payments or draws under the letter of credit facilities. Set forth in the following table is information about the City's letter of credit facilities supporting Senior Lien Obligations at O'Hare. As reflected in such table, a reduction in the City's debt rating for the related debt below the level that is shown in the "Ratings Thresholds" column would constimte an event of default under the related bank agreement.

If an event of default is triggered due to a ratings downgrade of the City or for any other reason, the subject bank would have the right to provide the bond trustee with a notice directing a mandatory tender of the related bonds. For such mandatory tender, the bond trustee would draw upon the letter of credit facility to fund the purchase price for such bonds. In such case, the bonds would be owned by the bank and would be immediately repayable at the option ofthe bank.

Airport PFC Obligations :

Existing PFC Obligations. The City has previously issued various series of PFC Obligations, pursuant to the'PFC Master Indenture. There are currently $5,95 !630 million aggregate principal amount of PFC. Obligations outstanding'under the PFC'Indenture.', PFC Obligations are1 secured separately' from; the Senior Lieri Bonds,"solely by PFCs collected by me City at
Issuance of Additional PFC Obligations. The City has the authority to issue an additional $500 million of PFC Obligations. The City may issue, from time to time, additional PFC Obligations to fund projects under the 2016-2020 CIP and to fund the OMP Completion Phase 2B (including additional costs ofthe OMP Completion Phase Noise Program), as described, under "CAPITAL PROGRAMS." See "CERTAIN INVESTMENT CONSIDERATIONS-Future Indebtedness" and "-Availability of PFC Revenues." Within the first six months of 2017, the City plans to issue the,2017 PFC Bonds to pay the costs of certain projects included in the OMP, fund the related reserve requirements, refund certain outstanding PFC Obligations and pay the related costs of issuance of the 2017 PFC Bonds, as more fully described under "PLAN OF FINANCE" herein.

Obligations Subordinate to Pledge of PFC Revenues. The City has the right to issue debt payable from or secured by PFC Revenues remaining after the discharge and satisfaction of all PFC Obligations and to issue debt payable from, or secured by a pledge of amounts to be withdrawn from the PFC Bond Fund so long as such pledge is expressly junior and subordinate to the pledge of PFC Revenues to the payment of PFC Obligations. Indebtedness ofthe type described in the preceding sentence can be issued without limit as to nature or amount.

Airport CFC Obligations

The City has previously issued its $248,750,000 Customer Facility Charge Senior Lien Revenue Bonds, Series 2013 (the "CFC Bonds") pursuant to an Indenture of Trust, dated as of August 1, 2013, as supplemented and amended (the "CFC Indenture"). In addition, the City has entered into a Transportation Infrastructure Finance and Innovation Act of 1998 loan with the U.S. Department of Transportation, which will provide funding in an aggregate principal amount up to $272,100,000 (the "TIFIA Loan" and

48

together with the CFC Bonds, the "CFC Obligations"), and which constitutes a subordinate bond under the CFC Indenture. The proceeds of the CFC Obligations, together with other moneys, arc being used to finance the construction of the Multi-Modal Facility, and the CFC Obligations arc secured separately from the Senior Lien Obligations, solely by CFCs collected from customers of rental car companies operating at O'Hare and certain other charges payable by rental car companies operating from the CRCF.

Special Facility Revenue Bonds
The City has previously issued Special Facility Revenue Bonds on behalf of numerous airlines, as well as certain non-airline parties, to finance or refinance a portion of the capital improvements at O'Hare. These Special Facility Revenue Bonds are secured separately from the Senior Lien Bonds, solely by amounts received from such airlines and non-airline parties pursuant to the terms of related Special Facility Financing Arrangements. See "CERTAIN INVESTMENT CONSIDERATIONS-Uncertainties ofthe Airline Industry."
PFC PROGRAM AT O'HARE

The description of the PFC Program at O'Hare is included within this Official Statement for the benefit of the 20J6C Senior Lien Bonds to the extent the 2016C Senior Lien Bonds are payable from Pledged PFCs. The PFCs collected at O'Hare are not included within the Revenues.

General
The United States Congress enacted the PFC Act in 1990, authorizing a public agency, such as the City, which controls a commercial service airport to charge each paying passenger enplaning at such airport (subject to limited exceptions) a PFC of $1.00, $2.00 or $3.00. The purpose of the PFC "is to provide additional capital funding for the expansion of the national airport system. The proceeds from PFCs are to be used to finance eligible airport-related projects that preserve or enhance safety, capacity or security of the national air transportation system; reduce noise from an airport that is part of such system; or furnish opportunities for enhanced competition between or among air carriers.

PFCs are collected on behalf of airports by air carriers and their agents (the "Collecting Carriers "j and remitted to the City on a monthly basis. On September 1, 1993, pursuant to a PFC Approval, the City began to impose PFCs at O'Hare at the rate of $3.00 per eligible enplaned passenger.

The Wendell H. Ford Aviation Investment and Reform Act for the 21st Century ("AIR 21"), among other things, authorizes eligible public agencies, such as the City, to impose PFCs of $4.00 or $4.50 to finance PFC eligible projects, including the payment of debt service on indebtedness incurred to finance such projects, that cannot be paid for from funds reasonably expected to be available through the federal Airport Improvement Program (the "AIP"). On April 1, 2001, pursuant to authorization contained in AIR 21 and amended PFC Approvals (as herein defined) received from the FAA, the City began imposing PFCs at O'Hare at the rate of $4.50 per eligible enplaned passenger. Regardless ofthe number of PFC applications which have been approved by the FAA, eligible public agencies, such as the City, only can collect a maximum of $4.50 from each eligible enplaning passenger.

Collection of the PFCs
A PFC may be collected from a passenger for no more than two boardings (i) on a one-way trip or (ii) in each direction of a roundtrip. The public agency may request exemption from the requirement to collect PFCs for a class of air carriers if the number ol'passengers enplaned by the carriers in the class constitutes no more than one percent ofthe total enplaned passengers annually at the airport at which the


49
PFC is imposed. The City has requested and received an exemption from the collection of PFCs for air taxi operators at O'Hare. Air taxi operators have historically accounted for less than one percent of all PFC eligible enplanements at O'Hare.

Treatment of PFCs in Airline Bankruptcies. The PFC Act provides that PFCs collected by; the Collecting Carriers constitute a trust fund held for the beneficial interest ofthe eligible public agency (i.e., the City) imposing the PFCs, except for any handling fee or retention of interest collected onunremitted proceeds. In addition, federal regulations require airlines to account for PFC collections separately and to disclose the existence and amount of funds regarded as trust funds for financial statements. However, the ~C3llectWg: Gamere ^
to retain interest earned on PFC collections until such PFC collections are remitted.

In the event of a bankruptcy, :the PFC Act, as amended in December 2003 by the Vision 100— Century of Aviation Reauthorization Act ("Vision 100"), provides certain statutory protections5 to eligible public agencies imposing PFCs, including the City, with respect to PFC collections. It is unclear, however, whether the City would be able' to 'recover the full amount of PFC trust funds collected or accrued with respect to a Collecting Carrier in the event of a liquidation or cessation of business. Vision 100 requires an airline' that files for bankruptcy protection; or that has 'an- involuntary bankruptcy proceeding commenced against it, to segregate passenger facility revenue in' a separate account for the benefit of the eligible public agencies entitled' to such revenue. Prior to-the amendments made'by Vision 100 allowing PFCs collected by airlines to constitute a trust fund, at least one bankruptcy court indicated that PFC revenues held by an airline in bankruptcy would not be treated as a trust fund and would instead be subject to the general claims of the unsecured creditors of such airline. In connection with another bankruptcy proceeding prior to Vision 100, a different bankruptcy court entered a stipulated order establishing a PFC trust'fund for'the benefit "of various airports' to-which thVbarilcrupt' airline' was'iiot current on PFC payments'. While'Visioh 100 should provide sdrte'protectiohfo'r'clig^ble public agencies in connection with PFC revenues collected by an airline in bankruptcy, no assurances can be given as to the approach bankruptcy courts will follow in the future. See "CERTAIN INVESTMENT CONSIDERATIONS—Effect of Airline Bankruptcy ."

The City also cannot predict whether a Collecting Carrier operating at O'Hare that files for bankruptcy would have properly accounted for PFCs' owed to the City or whether the bankruptcy estate would have sufficient moneys to pay the City in full for PFCs owed by such Collecting Carrier. Based on Vision 100, it is expected, although no assurance is given, that the City'would be treated as a secured creditor with respect to PFCs held by a Collecting Carrier which becomes involved in a bankruptcy proceeding. Sec "CERTAIN INVESTMENT CONSIDERATIONS—Effect of Airline Bankruptcy."
The City's PFC Approvals
Since 1993, the FAA has approved several PFC applications and amendments submitted by the City authorizing the City to use PFCs to pay (i) allowable costs of projects approved by the FAA for PFC funding ("Approved Projects"), including those Approved Projects financed or refinanced by the issuance of the Series 2001 PFC Bonds, the Series 2008 PFC Bonds, the Series 2010 PFC Bonds, the Series 2011 PFC Bonds (each series as defined in APPENDIX A-"GLOSSARY OF TERMS") and the planned 2017 PFC Bonds, together with debt service on the Series 2001 PFC Bonds, the Series 2008 PFC Bonds, the Series 2010 PFC Bonds, the Series 201 1 PFC Bonds and the planned 2017 PFC Bonds, and (ii) allowable costs of certain Approved Projects on a "pay as you go" basis.

As ofthe date of this Official Statement, the City has authority to impose and use at O'Hare up to $6.55 billion in PFCs. Based upon the City's current PFC authority, the FAA estimates the PFC collection expiration date lo be February 1, 2039. See Exhibit 5-7 in APPENDIX E-"REPORT OF

50

THE AIRPORT CONSULTANT" for a description of PFC Revenues anticipated to be received by the City through 2025. Although the City expects that it will obtain new PFC Approvals before its current authority expires, no assurance can be given that the City will be able to do so. Regardless, the 2016C Senior Lien Bonds are also payable from and secured by a pledge of Revenues. See "SECURITY FOR THE 2016 SENIOR LIEN BONDS."

The City is in the process of submitting to the FAA an application for PFC authority for the International Terminal expansion project. This will support the issuance ofthe 2017 PFC Bonds in the approximate principal amount of $188.6 million to fund the International Terminal expansion project. Additional International Terminal Expansion project costs, if determined to be PFC-eligible based upon project refinements, could be funded with PFC Revenues.

Termination of Authori ty to Impose PFCs
The FAA may terminate the City's authority to impose PFCs, subject to procedural safeguards, if the FAA determines that (i) the City is in violation of certain provisions of the federal Airport Noise and Capacity Act of 1990 (the "Noise Aci") relating to airport noise and access restrictions, (ii) PFC collections and investment income thereon are not being used for Approved Projects in accordance with the PFC Approvals or with the PFC Act and the PFC Regulations, (iii) implementation of any Approved Projects does not commence within the time period specified in the PFC Act and the PFC Regulations or (iv) the City is otherwise in violation of the PFC Act, the PFC Regulations or the PFC Approvals. As provided by the PFC Regulations, a formal termination process that would last a minimum of 100 days would be required before the FAA could terminate the City's authority to impose a PFC for a violation of the PFC Act. The City has not received notice of any such determination by the FAA and has no reason to believe that it is in violation ofthe PFC Act or the PFC Regulations. See "SECURITY FOR THE 2016 Senior Lien BONDS-Certain Provisions of PFC Indenture-Compliance with Noise Act, PFC Act, PFC Regulations and PFC Approvals."

In the event the FAA were to terminate or reduce the City's ability to impose PFCs at O'Hare, such action would have the resultant effect of limiting the amount of PFC Revenues available for payment of the 2016C Senior Lien Bonds and the other Senior Lien Bonds to the extent such Senior Lien Bonds are payable from Pledged PFCs. The 2016C Senior Lien Bonds and any Senior Lien'Bonds payable from Pledged PFCs are also payable from and secured by a pledge of Revenues in the event insufficient PFCs are available for payment of these bonds. See "SECURITY FOR THE 2016 SENIOR LIEN BONDS."

Capital Programs

General

The Capital Programs are organized into the OMP, the 2016-2020 CIP and other recently announced capital projects. In addition to the Capital Programs, the City, in accordance with criteria established by the O'Hare Noise Commission, participates in an ongoing program of providing sound insulation to eligible schools and residences in the vicinity of O'Hare (the "OMP Noise Program"). See "CHICAGO OMFIARE INTERNATIONAL AIR PO RT-O 'Hare Noise Compatibility Commission."
OMP Airfield Projects

Overview. The OMP Airfield Projects were designed to enhance both O'Hare and system-wide airport capacity. The FAA's final Environmental Impact Statement ("EIS") defines the purpose and the need for the OMP development as addressing the projected needs of the Chicago Region by reducing delays at O'Hare, thereby enhancing capacity ofthe National Airspace System ("NAS"), and ensuring that

51
existing and future terminal facilities and supporting infrastrticture can-efficiently accommodate airport users. See APPENDIX E- 'REPORT OF THE AIRPORT CONSULTANT" for a more detailed discussion of the OMP'.

OMP Airfield Projects are changing the airfield from a layout with intersecting runways to a modern parallel runway system. The OMP, which includes the construction of one new runway, the relocation of three existing runways and the extension of two existing runways, is being undertaken in phases that, began in 2005. To date, three ofthe four runways have been completed and one of the two runway extensions has-been completed The Airport has experienced a reduction in operational delays andTaTFihCTca^^^ complefiori'^
Airfield Projects include one runway (9R-27C) (under, construction), and an extension to an existing runway (R-27L), which is expected to further reduce delays and increase capacity. Funding for the OMP Airfield Projects has been undertaken in phases. OMP Phase 1-,- a $3.21 billion project; included two runways and an extension and was completed in 2013. A $1.07 billion funding agreement with the Airline iBartiesifor .OMP; Phase: -2A included a runway sand; enabling projects for !a< ramre/runway. This phase is fully funded; the runway project was completed in October 2015 and the remaining, projects^ are anticipated to remain within budget... >

2016 Airport Projects

Proceeds from the 2016 New Money Bonds, if issued, will be used to fund the 2016 Airport Projects which include, construction of Runway 9C-27C and enabling projects, including airline facility relocation (these projects are part of the OMP); a centralized deicing pad, and a cross-field- taxiway system; and relocation of Taxiways A and B. PFCs and grant receipts from FAA LOI Grants, both used on a .PAYGO .basis,-, arc anticipated to fund the portions ofthe 2016 Projects not funded with the 2016 New Money Bonds. For a discussion of the 2016 Airport Projects, see APPENDIX E-"REPORT OF THE AIRPORT CONSULTANT-The Airport Facilities, Capital Program, and 2016 Projects."

Capital Improvement Program

. The 2016-2020 CIP addresses ongoing capital needs at O'Hare. In .general, ithe 2016-2020 CIP provides for rehabilitation of airfield pavement, lighting and mechanical upgrades for the terminals, mechanical and electrical upgrades to the heating and refrigeration plant and additional projects associated with the airfield and support facilities, parking and roadway projects, terminal area projects, and safety and security projects. The 2016-2020 CIP is expected to be funded through a combination of sources including federal grants, proceeds from previously issued GARBs and assumed proceeds from future Senior Lien Bonds. The 2016 Airport Projects do not include any projects that arc included in the 2016-2020 CIP. Certain projects, totaling approximately $991.5 million, were included in previous O'Hare five-year capital improvement programs.

The City is constructing a six-story, 4.5 million square foot Multi-Modal Facility which includes the CRCF with an Associated Quick Turn Around facility, an extension to O'Hare's existing ATS,

including the purchase of new ATS vehicles, and public parking. The Multi-Modal Facility is a major portion of the 2016-2020 CIP. The $784.5 million estimated cost of this project is fully funded and all approvals and waivers required from the rental car operators to operate in the CRCF have been received. Construction of the Multi-Modal Facility began in August 2015 and is expected to be complete in 2019.
For more information regarding the CIP, see "The Airport Facilities, Capital Program, and 2016 Projects-Overview of Capital Program-2016-2020 Capital Improvement Program" in APPENDIX E- 'REPORT OF THE AIRPORT CONSULTANT."
Other Recently Announced Capital Projects
The City recently announced a series of capital projects intended to bring the Airport facilities into the 21st Century. These projects will add gates at the domestic and international terminals, are expected to be completed over the next two to three years and do not require airline approval. The expansion ofthe International Terminal is expected to be funded using proceeds of the 2017 PFC Bonds. Additional long-term terminal development and redevelopment options as part of the TAP are being evaluated in coordination with airline representatives to address long-term terminal capacity. A redevelopment of the existing terminal hotel and the construction of two new hotels on Airport property are also planned and expected to be completed between 2020 and 2022. The feasibility of a future express rail third-party project connecting the Airport to the central business district is currently being studied..The expansion of Concourse. L.is under construction and will be funded by American Airlines. The $266.8 million International Terminal expansion is anticipated to be funded by PFC Revenue (PAYGO and PFC Revenue bonds) and Airport discretionary funds. The TAP is still in preliminary conceptual planning and discussion phases but expected to be funded with future bond proceeds. . For additional information on the recently announced capital projects, see "APPENDIX E-"REPORT. OF THE AIRPORT CONSULTANT-The Airport Facilities, Capital Program, and 2016 Projects- -Overview of Capital Program-Other Recently Announced Capital Projects."

Management Approach for Capital Programs

For the OMP, United Airlines and American Airlines established a tiered management structure with each tier having specific review and approval authority. The OMP Executive Working Group, comprised of three City representatives and two airline representatives, meets to review and discuss program scope, schedule, budgets and funding. A committee of the Airline Parties retains the right to approve increases in project component scope and budget of more than 10 percent, any financial commitment of over $5 million, and project delivery methods if construction value is greater than $20 million.

For all other Capital Programs, the City employs a construction manager to coordinate, supervise and inspect capital project construction. The construction manager prepares and maintains records on the progress of each capital project. The City and the construction manager oversee all work to ensure that each project is constructed in accordance with its plans and specifications within the timelines set forth in the construction schedule. In addition, the Airline Parties designate a construction representative to assess the construction and operational impact of capital projects and to participate in the evaluation of design and construction.

Federal Legislation, State Actions and Proposed South Suburban Airport

Federal Legislation. On July 15, 2016, President Obama signed the "FAA Extension, Safety and Security Act of 2016" into law. The law reauthorizes the Federal Aviation Administration ("FAA") operations and programs through September 30, 2017. On September 29, 2016, Public Law Number


53

114-223, a continuing resolution extending funding for federal programs, was signed into law (the "Continuing Resolution"). The Continuing Resolution extends federal funding, including general funding for the FAA, including airport development grants and other non-trust funds, through December 9, 2016. As of the date of this Official Statement, the City has no assurance that the current FAA authorization-and' programs will be extended or that a new authorization or programs will be approved beyond September 30, 2017, or that no interruption of general federal funding, including FAA funding, will occur in connection with the current December 9, '2016 funding expiration date. ^ -See - "CERTAIN INVESTMENT CONSIDERATIONS."
O'HaFe'Modernization Act. The ~0'Hare"M611^
became law in August 2003, was created to expedite and facilitate the OMP. Specifically, the O'Hare Modernization Act 'states the Illinois General Assembly's intent that "all agencies'of this State and its subdivisions shall facilitate the efficient and expeditious completion" of the OMP. Among other things, the 0'Hate Modernization Act eliminates duplicative aeronautics review of the OMP under the Illinois Aeronautics' Act and grants quick-take authority to'the City for land acquisition associated with the OMP. The O'Hare Modernization Act also amends other laws to facilitate the OMP. '
Public Act"99-0202, which was effective on January 1,'2016,'was signed by Governor Rauner on July-30- 2015,:ahd- amended the O'Hare Modernization Act to increase from eight ;to¦ State* Approval of Federal Grants. ¦ ¦ Under, the Illinois. Aeronautics Acty-the City is. generally required to obtain the approval of Illinois Department of Transportation for all AIP:grant applications that the City submits to-the FAA.-i The O'Hare Modernization Act;provides that' this requirement does hot apply'to AlP'graht'applications* related to the<©MP)ariti further' provides-'that the; Oity> may'directly ''accept-receive and disburse AIP grant funds related to the OMP.

Proposed South Suburban Airport. Plans to build a third airport in the Chicago Region have been discussed for many years. The most likely site for such an airport is the proposed South Suburban Airport site located near Peotone, Illinois (in: Will County approximately 35 miles south of the City's central business district).
It is not possible at this time .to determine the viability of a new major commercial airport at the Peotone site or to .predict whether or when any new. regional airport would be constructed;, nor is at currently possible to predict what effect, if any, such an airport would have on'operations or enplanements at O'Hare.

Future Legislation. O'Hare is subject to various laws, rules and regulations adopted by the local, State and; federal governments and their agencies. The City is unable to predict The adoption or amendment of any such laws, rules or regulations, or their effect on the operations or financial condition of O'Hare;
Certain Investment Considerations

The purchase of 2016 Senior Lien Bonds involves certain investment risks and considerations. Prospective investors should read this Official Statement in its entirety. The factors set forth below, among others, may affect the security for the 2016 Senior Lien Bonds.





54

General Factors Affecting Level of Airline Traffic and Revenues
The 2016 Senior Lien Bonds are payable from and secured by a pledge of the Revenues and certain Funds and Accounts held under the Senior Lien Indenture. Revenues are dependent primarily on the level of aviation activity and enplaned passenger traffic at O'Hare. Key factors affecting airline traffic at O'Hare include, among others, (i) population growth and the economic and political conditions of the region and the nation, (ii) the financial health of the airline industry and of individual airlines, (iii) airline service and route networks, (iv) capacity of the national air traffic control system and of O'Hare and other competing airports, (v) national and international disasters and hostilities, (vi) safety concerns arising from international conflicts, the possibility of terrorist or other attacks, and (vii) various other local, regional, national and international economic, political and other factors. Many of these factors, most of which are outside the City's control, are discussed in detail in APPENDIX E- 'REPORT OF THE AIRPORT CONSULTANT." If aviation activity at O'Hare does not meet forecast levels, a corresponding reduction may occur in Revenues (absent an increase in O'Hare rentals, fees and charges).
Uncertainties of the Airline Industry
General. The City's ability to collect Revenues is affected by the dynamics ofthe airline industry, which also affect the ability ofthe Airline Parties, individually and collectively, to meet.their respective obligations under the Airport Use Agreements and other arrangements.
Historically, the financial performance of the airline industry generally has correlated with the strength of the national and global economy. Certain factors that may materially affect O'Hare and .-the airlines include, but are not limited to, (i) growth of population and the economic health of the region and the nation, (ii) airline service and route networks, (iii) national and international economic and political conditions, (iv) changes in demand for air travel, (v) service and cost competition, (vi) mergers and bankruptcy of any airlines, (vii) the availability and cost of aviation fuel and other necessary supplies, (viii) levels of air fares, fixed costs and capital requirements, (ix) the cost and availability of financing, (x) the capacity of the national air traffic control system, (xi) national and international disasters and hostilities, (xii) public health concerns, such as the spread of influenza and severe acute respiratory syndrome, (xiii) the cost and availability of employees and labor relations within the airline industry, (xiv) regulation by the federal government, (xv) environmental risks, noise abatement concerns and regulation, (xvi) acts of war or terrorism, (xvii) aviation accidents, and (xviii) other risks. As a result of these and other factors, many airlines have operated at a loss in the past and many (including some that served O'Hare) have filed for bankruptcy, ceased operations and/or merged with other airlines. In addition, the so-called legacy carriers have taken many actions to restructure and reduce costs including reducing their workforce, renegotiating their labor agreements, reducing routes served, consolidating connecting activity and replacing mainline jets with regional jets.
Financial Condition of Airlines Serving O'Hare. Many of the airlines serving O'Hare were impacted by the global economic downturn and recession that occurred between 2008 and 2009, and most major domestic airlines suffered significant financial losses. While the U.S. and global economies generally have rebounded, there can be no assurances that any such rebound will continue, or that other national or international fiscal concerns will not have an adverse effect on the airline industry. Current and future financial and operational difficulties encountered by the airlines serving O'Hare (most notably United Airlines and its regional affiliates, which accounted for approximately 44.2 percent of the enplaned passengers at O'Hare in 2015, and American Airlines and its regional affiliates and US Airways, which accounted for approximately 35.8 percent of the enplaned passengers at O'Hare in 2015), could have a material adverse effect on operations at, and the financial condition of, O'Hare. If either United Airlines or American Airlines were to cease operations at O'Hare for any reason or eliminate or reduce



55
O'Hare's status as a connecting hub, the current level of activity of such airline may not be replaced by other airlines.

¦ Cost of-Aviation Fueh Airline earnings' are significantly affected by the price of aviation fuel:
Any increase in fuel prices results in an increase of airline operating costs. Fuel prices continue to be
impacted by, among, other things, political unrest in oil-producing parts ofthe world, increased demand
for fuel'caused by rapid growth in certain global economies, such, as China and India, currency
fluctuations'and changes in demand for and supply .of oil worldwide. Significant fluctuations and
prolonged periods of increases'in the cost of aviation fuel have had material'adverse effects on airline
profitability, causing airlines to reduce capacity,-fleet and personnel'asrwell! as increase fares and institute
additional fees,- such as-checked baggagefees, all of which may decrease demand for air travel. Although,
at present, aviation fuel prices have stabilized^ no assurance can be given that such fuel prices will not
increase in the-future, thereby negatively impacting airline earnings and operations. • ; ' • •
Airline Mergers, Acquisitions and Alliances. In response to competitive pressures and increased
costs, airlines have merged and acquired competitors in an attempt to combine operations in order to
increase cost synergies and become more competitive. In 2009, Delta merged with Northwest Airlines.
In'2010, United Air-lines and Continental Airlines merged. In April 2015, American and US Airways
completed their.merger which; crcate'd the largest-airline1 in the world in- terms'of Operating revenue'and'
revenue passenger miles. In addition; all of the large U.S. airline's are members-;of alliances with foreign-
flag airlines, which alliances, and other marketing arrangements, provide airlines with many of the
advantages of mergers; -Aliiarices-typically involve marketing; code-sharirig,: arid scheduling arrangements
to facilitate the transfer of pas'sengersbetween the;airlines. , ¦¦, :
Effect of AiRiiiNE Bankruptcy '¦¦-.'.• • ,: ;

• - American Airlines, United Airlines and other airlines operating at O'Hare have emerged from bankruptcy reorganization over the last several years. U.S. airlines may file for bankruptcy:protection in the future: See "-Uncertainties of the Airline Industry" above.: The cessation of operations: by an Airline Party with significant operations at O'Hare, such as United Airlines'or American Airlines, could have, a'matcrial adverse effect on:operations, Revenues (with the resultant effect on repayment of the 2016 Senior Lien Bonds) and the cost to the other airlines of operating at O'Hare.
In the event of bankruptcy proceedings involving an Airline Party, the debtor, or its bankruptcy trustee must determine within a time period determined by the court whether to assume or reject the applicable Airport Use Agreement. -In the event of assumption, the debtor.would be required to cure1 any prior defaults and to provide adequate assurance of firiure performance. .

Rejection of an Airport Use Agreement by any Airline Party that is a debtor in a bankruptcy proceeding would result in the termination of that Airport Use Agreement. Such rejection of an Airport Use Agreement would give rise to an unsecured claim of the City against the debtor's estate for damages, the amount of which is limited by the Bankruptcy Code. After application of certain , reserve funds, the amounts unpaid by the Airline Party as a result of its rejection of an Airport Use Agreement in bankruptcy would be included in the calculation of the fees and charges ofthe remaining Airlines Parties under their Airport Use Agreements. See APPENDIX C "SUMMARY OF CERTAIN PROVISIONS OF THE AIRPORT USE ACREEMENTS-General Commitment to Pay Airport Fees and Charges."
Capacity of National Air Traffic Control and Airpor t System
Capacity limitations ofthe national air traffic control systems continue.to cause aircraft delays and restrictions, both on the number of aircraft movements in certain air traffic routes and on the number


56

of landings and takeoffs at certain airports. These restrictions affect airline schedules and passenger traffic nationwide. The FAA has made certain improvements to the computer, radar and communications equipment of the air traffic control system in recent years, but no assurances can be given that future increases in airline and passenger traffic will not again adversely affect airline operations.
Expiration of Airport Use Agreements

The expiration date ofthe Airport Use Agreements is May 11, 2018. Most ofthe debt service on
the 2016 Senior Lien Bonds and the Outstanding Senior Lien Bonds becomes due after such date. It is
not possible to predict whether any airline will be contractually obligated to make payments, including,
among other things, for debt service on the 2016 Senior Lien Bonds, the Outstanding Senior Lien Bonds
or any other Senior Lien Bonds after the expiration date ofthe Airport Use Agreements in 2018. Upon
the expiration of the Airport Use Agreements, the City may enter into extensions of such agreements with
the airlines, enter into new agreements with the airlines, or impose rates and charges upon the airlines by
City ordinance. The City has covenanted in the Senior Lien Indenture (which extends beyond the
expiration of the Airport Use Agreements) to establish rentals, rates and other charges for the use and
operation of O'Hare such that Revenues (including rentals, fees and charges imposed on the airlines),
together with certain other moneys deposited with the Trustee, are sufficient to pay Operation and
Maintenance Expenses at O'FIare and to satisfy the debt service coverage covenants contained in the
Senior Lien Indenture. See "SECURITY FOR THE 2016 SENIOR LIEN BONDS-Debt Service
Coverage. Covenants."
Capital Programs Costs and Schedule
The estimated costs of, and the projected schedule for, the projects in the Capital Programs for O'Hare depend on various sources of funding, and are subject to a number of uncertainties. The ability of the City to complete these projects within the current budgets and on the current schedules may be adversely affected by various factors including: (i) estimating errors, (ii) design and engineering errors, (iii) changes to the scope of the projects, (iv) delays in contract awards, (v) material and/or labor shortages, (vi) delays due to airline operational needs, (vii) unforeseen site conditions, (viii) adverse weather conditions, (ix) contractor defaults, (x) labor disputes, (xi) unanticipated levels of inflation, (xii) litigation and (xiii) environmental issues. No assurance can be given that the costs of the projects will not exceed the current budget for these projects or that the completion will not be delayed beyond the currently projected completion dates. At present, the City is unable to estimate the costs associated with each of the risks identified above and the total impact of these risks if such events were to occur. In addition, the City may ultimately decide not to proceed with certain capital projects or may proceed with them on a different schedule, resulting in different results than those included in the projections shown in the Report ofthe Airport Consultant.
Future Indebtedness
As described under "CAPITAL PROGRAMS-OMP-Airfield Projects" and "CAPITAL PROGRAMS-Capital Improvement Program," the City expects that it will need to incur additional indebtedness, including the issuance of Senior Lien Bonds and PFC Obligations, to finance the Capital Programs. Also the City's plans of finance for the Capital Programs assume that PFC Revenues would be available in certain amounts and at certain times for the payment of a portion ofthe anticipated costs of such capital projects on a "pay as you go" basis and for the payment of a portion ofthe debt service on the Senior Lien Bonds, including without limitation the 2016C Senior Lien Bonds and PFC-Backed GARBs issued to pay the costs of the Capital Program. See "CAPITAL PROGRAMS." No assurance can be given that these sources of funding actually will be available in the amounts or on the schedules assumed. For a discussion ofthe availability of PFCs, see "-Availability of PFC Revenues" below.


57
The City's plans of finance with respect to the Capital Programs also include certain assumptions with respect to FAA LOI Grants and FAA AIP Grants. . FAA LOI Grants and FAA AIP Grants are subject to congressional appropriation, as well as automatic spending cuts, known as sequestration as described below in'"^Additional Federal Authorization and- Funding Considerations."1 Although the City considers such assumptions in its plans of finance to be reasonable, such assumptions are inherently subject to certain uncertainties and contingencies. Actual FAA LOI Grant Receipt and FAA AIP Grant Receipt funding levels and timing may vary and such differences may be material. See "CAPITAL PROGRAMS-OMP Airfield Projects" and APPENDIX E "REPORT OF THE AIRPORT CONSULTANT."

In addition to the Capital Programs, the City may, from time to time, determine to fund additional
capital projects at O'Hare prior to the maturity of the 2016 SeniorLien Bonds; the funding of which is not
reflected in the Projections set forth in the Report of the Airport Consultant. Such''additional capital-
projects may have separate plans of finance1 which-assume various sources of funding; deluding;'without

To the1 extent that any portion of the funding fa'ssumed-in'the plan of finance for''capital'projects-at: O'Hare is not available as'anticipated, the City may be acquired to issue Additional Senior Lien Bonds to pay 'the-costs- of'sucli capital 'projects -and' to-- increase air line/rates'and charges to pay "debt: service on-such' Additional Senior Lien Bonds and to fund the required coverage thereon. As ah alternative'1 to; issuing Additional Senior Lien Bonds, the City may ultimately decide not to proceed with certain capital projects or may proceed with them on a different schedule, producing different results than those ineluded in the projections shown in the Report of the Airport Consultant.
AVA'ILABIfcPFY-OF-PFG!R^EVENUES^"»Ji« ¦¦ - ;¦¦¦¦<¦ :'-'- -':- ::.-'•• '-'r'-: :-'''.-.-: v. '•" ¦

'¦•¦¦' As discussed !above under the subheading ^'-'-Future; Indebtedness," the plans of finance-for the OMP and the 2016-2020 CIP' assume-that PFC Revenues would be available in certain amounts and at certain'times'for the'payment of a portion ofthe anticipated costs of such capital projects on a "pay-as-you-go" as well as to secure additional Airport Obligations needed to fund such projects. In addition, the Report of the Airport Consultant, which sets forth'certain Projections regarding O'Hare^ assumes' that certain available PFC Revenues not otherwise pledged to pay PFC Obligations, Senior Lien Bonds (including the'2016C Senior Lien Bonds from Fiscal Year 2019 through maturity); and other payment obligations, will be applied by the City on a year-to-year basis as Other Available Revenues to pay debt service on such obligations. No assurance can be given that PFC Revenues will be available i in the amounts or on the schedules assumed.
The ability of the City to collect sufficient PFC Revenues depends upon a number of factors, including, without limitation, the number of enplanements at O'Hare, the use of O'Hare by the Collecting Carriers and the efficiency and ability ofthe Collecting Carriers to collect and remit PFCs to the City. The City relics on the Collecting Carriers' collection and remittance of PFCs* and both the City and the FAA rely upon the airlines'reports of enplanements and collections.
Under the terms of the PFC Act, the FAA may terminate the City's authority to impose a PFC if the City's PFC Revenues are not being used for approved projects in accordance with the FAA's approval, the PFC Act or the regulations promulgated thereunder, or if the City otherwise violates the PFC Act or regulations. The FAA may also terminate the City's authority to impose a PFC for a violation by the City of the Airport Noise and Capacity Act. The PFC termination provisions contained in the regulations provide both informal and formal procedural safeguards.



58

The PFC Act provides that PFCs collected by the airlines constitute a trust fund held for the beneficial interest ofthe eligible agency (i.e., the City) imposing the PFCs, except for any handling fee or retention of interest collected on unremitted proceeds. Furthermore, the FAA's PFC regulations require Collecting Carriers to account for PFC collections separately, and further indicate that such funds are to be regarded as trust funds held by the Collecting Carriers for the beneficial interest of the public agency imposing the PFC. Recent bankruptcy court decisions, however, indicate that in a bankruptcy proceeding involving a Collecting Carrier, it is likely that PFCs will not be treated as trust funds and that airports are not entitled to any priority over other creditors of the Collecting Carrier as to such funds. For more detailed information on treatment of PFCs in bankruptcy, see "PFC PROGRAM AT O'HARE-Collection of the PFCs."

ADDITIONAL FEDERAL AUTHORIZATION AND FUNDING CONSIDERATIONS

The City receives federal funding for O'Hare not only in connection with FAA AIP Grants and PFC authorizations, but also in the form of funding for the Transportation Security Administration ("TSA"), air traffic control and other FAA staffing and facilities. On July 15, 2016/ President Obama signed the "FAA Extension, Safety and Security Act of 2016" into law. This law reauthorizes FAA operations and programs through September 30, 2017. Th the event that the FAA Extension, Safety and Security Act of 2016 were to expire without a long-term reauthorization or another short-term extension, during such period FAA programs would be unauthorized, including FAA programs providing funding for: O'Hare. The City is unable to predict whether legislation to extend or reauthorize this statute or otherwise continue FAA programs will be adopted prior to the scheduled expiration date, if not so adopted, the duration of any resulting period of de-authorizatiori, and the impact on O'Hare finances which might result therefrom.
Federal funding is also impacted by sequestration, a budgetary feature first introduced under the federal Budget Control Act of 2011. Unless changed by the United States Congress from time to time, sequestration is a multi-year process and could continue to affect FAA, TSA and Customs and Border Control ("CBP") budgets and staffing, resulting in staffing shortages and traffic delays and cancellations at airports across the United States. The full impact of sequestration on the aviation industry and O'Hare, generally, resulting from potential layoffs or further furloughs of federal employees responsible for federal airport security screening, air traffic control and CBP, is unknown at this time.

Regulations and Restrictions Affecting O'Hare
The operations of O'Hare and its ability to generate revenues are affected by a variety of contractual, statutory and regulatory restrictions and limitations, including, without limitation, the provisions of the Airport Use Agreements, the PFC Act and other extensive federal legislation and regulations applicable to all airports in the United States. There is no assurance that there will not be any change in, interpretation of, or addition to any such applicable laws, regulations and provisions. Any such change, interpretation or addition may have a material adverse effect, either directly or indirectly, on O'Hare, which could materially adversely affect O'Hare's operations or financial condition.

In addition, following the events of September 11, 2001, O'Hare also has been required to implement enhanced security measures mandated by the FAA, TSA and the Department of Homeland Security. It is not possible to predict whether future restrictions or limitations on Airport operations will be imposed, whether future legislation or regulations will affect anticipated federal funding or PFC collections for capital projects for O'Hare, whether additional requirements will be funded by the federal government or require funding by the City or whether such restrictions or legislation or regulations would adversely affect Revenues.



59
Climate change concerns have led; and may continue to lead, to new laws and regulations at the federal and state levels that could have a material adverse effect on the operations of O'Hare and on the airlines operating at O'Hare. The United States Environmental Protection Agency (the "EPA") has taken steps'toward regulation of'greenhouse gas ("GHG") emissions under, existing federal law;.- These steps' may lead to further regulation of aircraft GHG emissions. No assurances can be given as to what any EPA emissions standards governing O'Hare or the airlines could be or what effect those standards may have on the City or the airlines operating at O'Hare.-
Competition
O'Hare competes with other U.S. airports for both domestic and international passengers. Portions of O'Hare's Air Trade Area are serviced by Midway and Mitchell. In 2015, Midway had enplanements representing approximately 25.3 percent of Chicago originating passenger traffic and approximately 18':8'"percent of Chicago connecting passenger-traffic.'Midway is expected'to continue to be : International passengers are also significant'at O'Hare, making up approximately 14.4% of all
passenger enplanements! in-2015: International-air travel may be more easily disrupted by .political
instability, terrorist activities, cuiTency:fluctuations and other-factors outside'the cohtrohof the'City. iThe
City cannot predict whether the level of international passengers .will remain stable or will grow, nor what
events, domestic or. iinternational, may adversely affect such air traffic. See (APPENDIX ¦E-'.'.REPORT
OF THE AIRPORT CONSULTANT-Air Traffic-Factors Affecting Aviation, Demand at the

Any j increases! in'operating'costs: atO'Hare mayi increase coststo theiairlines, which could result in O'Hare being : put into.' a competitive disadvantage relative to other-airports and other types of transportation:' For a discussion of the costsitO the; airlines of operating at O'Hare, see APPENDLX E-"REPORT OF THE AIRPORT CONSULTANT-Financial Analysis "
Impactof Regional andNational Economic Conditions on O'Hare.'. . „
The demand for air transportation is, to a degree, dependent upon the demographic and economic
characteristics of an airport's air trade area. This relationship is particularly true for O&D passenger
traffic, which has historically accounted for approximately 50 percent of demand at O'Hare. Although
O'Hare's Air Trade Area has a large, diverse economic base that supports business and leisure travel and
is projected by the Airport- Consultant to. experience continued growth,, there can be>no assurances that
any negative economic or political conditions affecting the Air Trade Area would not have an adverse
effect on demand for air transportation at O'Hare. See APPENDIX E-"REPORT OF THE AIRPORT
CONSULTANT-Demographic and Economic Analysis." . . . . . .

See "-Financial Condition of the City and Other Overlapping Governmental Bodies" below for a discussion of the implications for O'Hare of the current financial challenges faced by the City and other public bodies located within the Air Trade Area.

Financial Condition of the City and Other Overlapping Governmental Bodies
The 2016 Senior Lien Bonds are limited obligations ofthe City payable solely from the Revenues (and the 2016C Senior Lien Bonds are also payable from a subordinate pledge of PFC Revenues), and do not constitute an indebtedness or a loan of credit ofthe City and neither the faith and credit nor the taxing power ofthe City nor any property ofthe City is pledged as security for the 2016 Senior Lien Bonds. The


60

City is the issuer of the 2016 Senior Lien Bonds and the information under this heading regarding the City's financial condition and the financial condition of other governmental bodies sharing a common tax base is provided as information regarding certain factors that could impact the level of enplaned passenger traffic and aviation activity at O'Hare.
Unfunded Pensions. The Retirement Funds have significant unfunded liabilities and low funding ratios. The City's contributions to the Retirement Funds in accordance with the Pension Code have not been sufficient, when combined with employee contributions and investment returns, to offset increases in the Retirement Funds' liabilities, which has contributed to the significant undcrfunding of the Retirement Funds. Moreover, the contributions to the Retirement Funds in accordance with the Pension Code have had the effect of deferring the funding of the Retirement Funds' liabilities, which increases the costs of such liabilities and the associated financial risks, including the risk that each Retirement Fund will not be able to pay its obligations when due. Furthermore, increases in the City's contributions to the Retirement Funds (such as those scheduled to occur under Act 1495, as modified by Act 506) caused the City to increase its revenues and may require the City to further increase its revenues, reduce its expenditures, or some combination thereof, which may impact the services provided by the City or limit the City's ability to generate additional revenues for other purposes in the future.

In addition, the actuaries for MEABF and LABF project that such Retirement Funds will not have sufficient assets on hand to make payments to beneficiaries beginning in 2025 and 2027, respectively, based on the provisions of the Pension Code currently in effect. The City makes no prediction as to the impact of the insolvency of MEABF or LABF on the amount of the City's contributions to these Retirement Funds. However, should the City be required to contribute the amounts necessary to fund directly such payments to beneficiaries on a pay-as-you-go basis upon the insolvency of such Retirement Funds, the amount of the City's contributions to MEABF and LABF would substantially increase.

Overlapping Taxing Districts. A number of governmental units and other public bodies share in varying degrees a common tax base, including property taxes, with the City. The City does not control the amount or timing of the taxes levied by these overlapping taxing districts. Depending on the amount of such increase(s), an increase in the amount of taxes by these overlapping taxing districts could potentially be harmful to the City's economy and/or may make it more difficult for the City to increase taxes and maintain essential or necessary City services.

Municipal Bankruptcy
State Law Authorization. Municipalities, such as the City, cannot file for protection under the U.S. Bankruptcy Code unless specifically authorized to be a debtor by state law or by a governmental officer or organization empowered by state law to authorize such entity to be a debtor in a bankruptcy proceeding. State law docs not currently permit municipalities to be a debtor in a bankruptcy proceeding. However, from time to time, legislation has been introduced in the Illinois General Assembly which, if enacted, would permit Illinois municipalities to be a debtor in bankruptcy under the U.S. Bankruptcy Code. The Governor ofthe State recently proposed legislation to allow for municipal bankruptcy, and legislation has been introduced in the General Assembly to that effect. Further, on January 22, 2016, legislation was introduced in the Illinois General Assembly (House Bill 4499), specifically addressing the City, that would authorize the City to become a debtor in bankruptcy under either of two circumstances: (i) after the completion of a neutral evaluation process by the City as described in the legislation, or (ii) declaration by the City of a fiscal emergency and adoption of a resolution by the City Council that includes findings that the financial state of the City jeopardizes the health, safety, or well-being ofthe residents ofthe City absent the protections of Chapter 9 ofthe U.S. Bankruptcy Code. The City is unable to predict whether the Illinois General Assembly may adopt any such legislation or the form of such legislation if enacted.


61
Special Revenues. Although the City can provide no assurances, the City believes that Revenues and Other Available Moneys currently pledged by the City under the Senior Lien Indenture constitute "special revenues," as defined in Section 902(2) of the U.S: Bankruptcy Code, and 'therefore; pursuant-to; Section 928(a) ofthe U.S. Bankruptcy Code, any and all of such pledged Revenues and Other Available Moneys currently pledged by the City under the Senior Lien Indenture acquired by the City after the commencement of a case by the City under Chapter 9 of the U.S. Bankruptcy Code would remain subject to the lien of the Senior Lien Indenture and could not lawfully be used by the City other than in compliance with the Senior Lien Indenture. Under Section 922(d) of the U.S. Bankruptcy Code,' the application5 'by> th'e'-Gity :of'"specidl*reve'nues " 'under-* the 'terms' of'the- Senior 'Lien1 Indenture1 would'not be subject to stay after the commencement-by the City of a case under Chapter 9 of the U.S. Bankruptcy Code. See "SECURITY FOR THE SERIES 2016 BONDS-O'Hare Revenues Must Be Used For Airport Purposes."
Forge Majeure Events Affecting the City and O'Hare ¦ ; ¦ - ;
There are' certain unanticipated events beyond' the City's control that could- have a material adverse effect on the City's operations and financial condition, or on O'Hare's operations and financial condition, if they were to occur. These events'include fire, flood,: earthquake, epidemic,: adverse health conditions or other unavoidable casualties or acts of God,: ¦ freight embargo, labor strikes or work stoppages, civil-commotion, .new acts of war or escalation-of^existing war. conditions, sabotage, enemy action, pollution, unknown subsurface on concealed conditions affecting the environment, and any similar causes No-assurance: can;.be provided'that such, events will not occur, and, if any such events, were to occur, no'prediction can be .provided as to the actual impact;or severity of the impact on-the City's operations-and financial condition or-ori O'Hare's operations-and financial condition,: as applicable:
Enforcement Actions
The remedies available to bondholders upon nonpayment of principal of or interest on the 2016 Senior Lien Bonds are in many respects dependent upon judicial enforcement actions which are often subject to discretion and delay. See APPENDIX B "SUMMARY OF CERTAIN PROVISIONS OF THE SENIOR LIEN INDENTURE - Remedies."
Limited Obligations
The 2016 Senior Lien Bonds are limited obligations of the City and do not constitute an indebtedness or a loan of credit of the city within the meaning of any constitutional or statutory limitation, and neither the faith and credit nor the taxing power of the state of illinois, the city or any other political subdivision of the state of Illinois is pledged to the payment of the principal of or interest on the 2016 Senior Lien Bonds. The 2016 Senior Lien Bonds are not payable in any manner from revenues raised by taxation. No property of the City (including property located at O'Hare) is pledged as security for the 2016 Senior Lien Bonds.

The 2016 Senior Lien Bonds are secured on a parity basis with the Outstanding Senior Lien Bonds and all other Senior Lien Obligations. Subject to certain conditions set forth in the Senior Lien Indenture, the City may in the future issue Additional Senior Lien Bonds or incur other Senior Lien Obligations that will be secured on a parity basis with the 2016 Senior Lien Bonds and the Outstanding Senior Lien Bonds. See "SECURITY FOR THE 2016 SENIOR LIEN BONDS-Issuance of Additional Senior Lien Bonds" and "CAPITAL PROGRAMS."

ASSUMPTIONS IN THE REPORT OF THE AIRPORT CONSULTANT

In connection with the offering of the 2016 Senior Lien Bonds described in this Official Statement, the Airport Consultant has prepared the Report of the Airport Consultant, a copy of which is included as APPENDIX E to this Official Statement. The Report of the Airport Consultant contains numerous assumptions as to the utilization of O'Hare and other matters and includes the Projections. Projections and assumptions are inherently subject to significant uncertainties. Inevitably, some assumptions may not be realized and unanticipated events and circumstances may occur. Actual results arc likely to differ, perhaps materially, from those projected. Accordingly, the Projections contained in Report of the Airline Consultant are not necessarily indicative of future performance, and neither the Airport Consultant nor the City assumes any responsibility for the accuracy of such Projections. In addition, the final maturity date of each Series of the 2016 Senior Lien Bonds extends beyond the period of the Projections. See "INTRODUCTION - Report of the Airport Consultant" and APPENDIX E-"REPORT OF THE AIRPORT CONSULTANT."
The Projections are based, in part, on historic data from sources considered by the Airport Consultant to be reliable, but the accuracy of these data has not been independently verified. The Projections are based on assumptions made by the Airport Consultant concerning future events and circumstances which the Airport Consultant believes are significant to the Projections but which cannot be assured. Therefore, the actual results achieved may vary from the Projections, and such variations could be material.

Limited Liability Subordination
As described under the caption "SECURITY FOR THE 2016,SENIOR LIEN BONDS,".the
2016C Senior Lien Bonds are also payable from and secured by a pledge of Pledged PFCs to be derived from a subordinate pledge of PFC Revenues, including moneys to be withdrawn from the PFC Capital Fund. The pledge of PFC Revenues and moneys in the PFC Capital Fund as the source of the Pledged PFCs is subject to (i) the prior and superior pledge of and lien on the PFC Revenues and the moneys in the PFC Capital Fund as security for the payment of the outstanding PFC Obligations: and any future Scries of PFC Obligations, (ii) the payments by the City pursuant to the Compact, (iii) the City's right to issue additional Senior Lien Obligations that are also secured by PFC Revenues, including moneys to be withdrawn from the PFC Capital Fund, on a parity with the 2016C Senior Lien Bonds, and (iv) the City's right to issue Subordinated PFC Obligations that are secured by a pledge of and lien on the PFC Revenues and the moneys in the PFC Capital Fund that are superior to the pledges and liens created by the Fifty-Fourth Supplemental Indenture. Subject to certain conditions set forth in the PFC Indenture, the City may in the future issue (a) additional PFC Obligations that will be senior and superior to the claim of the Pledged PFCs and (b) Subordinated PFC Obligations (including additional CP Notes) that may be secured by a pledge of and lien on the PFC Revenues and moneys in the PFC Capital Fund that is senior and superior to the pledge and lien on the Pledged PFCs securing the 2016C Senior Lien Bonds. See "SECURITY FOR THE 2016 SENIOR LIEN BONDS—Certain Provisions ofthe PFC Indenture— Issuance of PFC Obligations."

Forward-Looking Statements
This Official Statement contains certain statements relating to future results that are forward-looking statements. When used in this Official Statement, the words "estimate." "intend," "expect" and similar expressions identify forward-looking statements. Any forward-looking statement is subject to uncertainty and risks that could cause acnial results to differ, possibly materially, from those contemplated in such forward-looking statements. Inevitably, some assumptions used to develop forward-looking statements will not be realized or unanticipated events and circumstances may occur.


63
Therefore, bondholders and potential investors should be aware that there are likely to be differences between forward-looking statements and actual results; those differences could be material. The City does not undertake any obligation to update or revise publicly any forward-looking statements, whether as a result-of new information, future events or otherwise.-1 See "INTRODUCTION - Regarding Use of the Official Statement."
Litigation

There is no litigation pending or threatened against the City relating to the City's operation of O'Hare, the issuance, sale, or delivery of .the 2016: Senior Lien Bonds, the validity or enforceability thereof;' or: the 'implementation/ construction' or' operation of the 'OMP, the'20l'6-2020 "CIP" projects; the' Multi-Modal Facility or the 2016 Airport Projects, other than various legal proceedings (pending or threatened) which may have arisen1 or may arise'out of the ordinary course of business of O'Hare. The City expects that the final resolution of such legal proceedings arising in the ordinary course of business will not have a material adverse effect on the financial positioner the: results['of Operation of O'Hare. " "
There are, from time to time, lawsuits2 that arise out of the various construction contracts entered into in connection with construction projects at; O'Hare. The City, however, does not believe that any sums that may be recovered would have a material adverse impact on the financial condition of O'Hare.

Tax Matters •

Summary of Co-Bond Counsel Opinion. Katten Muchin Rosenman LLP and Neal & Leroy, LLC,
Co-Bond Counsel, are of the opinion that under existing law, interest on the 2016 Senior Lien Bonds is;
not includable in the gross income of the owners thereof for federal income tax purposes. If there is
continuing compliance with the 'applicable requirements; of the Internal Revenue Code of 1986 (the
"Code"),"Co-Bbnd' Cbunselarebf the 'opinion''that- interest ori the 2016' Senior "Lien Bbrid's-will'cdntinUe tb
be excluded from the gross income ofthe owners thereof for federal income tax purposes, In addition, (i);
interest on the 2016A Senior Lien Bonds is an item of tax preference for purposes of computing1
individual and-corporate alternative minimum taxable income for purposes of the individual and corporate
alternative minimum' tax and (ii) interest on the 2016B Senior Lien Bonds and'the 2016C'Senior Lieri
Bonds is not an item of tax preference for purposes of computing individual Or corporate alternative
minimum taxable income but is includible in' corporate earnings and profits when computing, for
example, corporate alternative minimum taxable income for purposes of the corporate alternative
minimum tax. Co-Bond Counsel express no opinion as to the exclusion from gross'income for federal
income tax purposes of interest on any 2016A Senior Lien Bond-for any period during2 which such Bond
is held by a person "who is a "substantial user" of the facilities financed or refinanced with'the proceeds of
such Bond or & "related person" (each as defined in Section 147(a) ofthe Code). Interest on the 2016
Senior Lien Bonds is not exempt from Illinois income taxes. ! '
Exclusion from Gross Income: Requirements. The Code contains certain requirements that'must be satisfied from and after the date of issuance of the 2016 Senior Lien Bonds in order to preserve the exclusion from gross income for federal income tax purposes of interest on the 2016 Senior Lien Bonds. These requirements relate to the use and investment ofthe proceeds of the 2016 Senior Lien Bonds, the payment of certain amounts to the United States, the security and source of payment of the 2016 Senior Lien Bonds and the use of the property financed with the proceeds ofthe 2016 Senior Lien Bonds. Among these specific requirements are the following:
(a) Investment Restrictions. Except during certain "temporaiy periods," proceeds of the 2016 Senior Lien Bonds and investment earnings thereon (other than amounts held in a reasonably required reserve or replacement fund, if any, or as part of a "minor portion") may



64

generally not be invested in investments having a yield that is materially higher than the yield on the 2016 Senior Lien Bonds.
Rebate of Permissible Arbitrage Earnings. Earnings from the investment of the "gross proceeds" of the 2016 Senior Lien Bonds in excess ofthe earnings that would have been realized if such investments had been made at a yield equal to the yield on the 2016 Senior Lien Bonds are required to be paid to the United States at periodic intervals. For this purpose, the term "gross proceeds" includes the original proceeds ofthe 2016 Senior Lien Bonds, amounts received as a result of investing such proceeds and amounts to be used to pay debt service on the 2016 Senior Lien Bonds.
Restrictions on Ownership and Use. The Code includes restrictions on the ownership and use of the facilities financed with the proceeds of the 2016 Senior Lien Bonds. Such provisions may restrict future changes in the use of any property financed with the proceeds of the 2016 Senior Lien Bonds.
Covenants to Comply. The City covenants in the Senior Lien Indenture to comply with the requirements of the Code relating to the exclusion from gross income for federal income tax purposes of interest on the 2016 Senior Lien Bonds.
Risk of Non Compliance. In the event that the City fails to comply with the requirements of the Code, interest on the 2016 Senior Lien Bonds may become includable in the gross income of the owners thereof for federal income tax purposes retroactively to the date of issue. In such event, the Senior Lien Indenture does not require acceleration of payment of principal of or interest on the 2016 Senior Lien Bonds or payment of any additional interest or penalties to the owners of the 2016 Senior. Lien Bonds.
Federal Income Tax Consequences. Pursuant to Section 103 of the Code, interest on the 2016 Senior Lien Bonds is not includible in the gross income of the owners thereof for federal income tax purposes. However, the Code contains a number of other provisions relating to the treatment of interest on the 2016 Senior Lien Bonds that may affect the taxation of certain types of owners, depending on their particular tax situations. Some of the potentially applicable federal income tax provisions are described in general terms below. PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR TAX ADVISORS CONCERNING THE PARTICULAR FEDERAL INCOME TAX CONSEQUENCES OF THEIR OWNERSHIP OF THE 2016 Senior Lien Bonds.
Cost of Carry. Owners of the 2016 Senior Lien Bonds will generally be denied a deduction for otherwise deductible interest on any debt that is treated for federal income tax purposes as incurred or continued to purchase or carry the 2016 Senior Lien Bonds. Financial institutions are denied a deduction for their otherwise allowable interest expense in an amount determined by reference to their adjusted basis in the 2016 Senior Lien Bonds.
Corporate Owners. As set forth in "Summary of Co-Bond Counsel Opinion" above, interest on the 2016 Senior Lien Bonds is taken into account in computing earnings and profits of a corporation and consequently may be subject to federal income taxes based thereon. Thus, for example, interest on the 2016 Senior Lien Bonds is taken into account in computing corporate alternative minimum taxable income, the branch profits tax imposed on certain foreign coq^orations, the passive investment income tax imposed on certain S corporations, and the accumulated earnings tax.

. 2016 Senior Lien Bonds Purchased at a. Premium or at a Discount.¦• The difference (if any) between the initial price afwhich a substantial-amount of each maturity of each Series of the 2016 Senior Lien Bonds is sold to the public (the "Offering Price") and the principal amount payable at :maturity of such 2016 Senior Lien Bonds is given special treatment for federal income tax purposes. If the Offering Price is higher than the maturity value of a Bond, the difference between the twO is known as "bond premium; " if the Offering Price is lower than the maturity value of a Bond, the difference between the 'two is'known as "original'issuediscount."¦>¦'¦
: Bond premium and1 original issue discount-are ;amortized over the term of a 2016 Senior Lien' Bond on the basis of the owner's yield from the date of purchase to the date of maturity, compounded at the end of each accrual-period of one year or less with straight-line interpolation between compounding dates, as provided'more specifically in the Income Tax Regulations. The amount of bond.premium accruing during each period is treated as an offset against interest paid on the 2016 Senior Lien-Bonds and is subtracted from the owner's tax basis in the 2016 Senior Lien Bond. The amount of original issue-discount accruing-during each^period is treated as interest that is excludable from the gross-income of the owner of such 2016 Senior Lien Bond for federal income tax purposes, to the same extent and with the same limitations1 as current interest, and is added to the owner's tax basis in the 2016 Senior Lien Bond. A 2016 Senior Lien Bond's adjusted tax basis is used to determine whether, and to what extent, the owner realizes taxable gain or loss upon the disposition of the 2016 Senior Lien Bond (whether by reason of sale, acceleration, redemption prior to maturity or payment at maturity ofthe 2016 Senior Lien Bond).
Owners who purchase 2016 Senior Lien Bonds at a price other than the Offering Price, after the termination of the initial public offering or at a market discount should consult their tax advisors with respect to the tax consequences of their ownership of the 2016 Senior Lien Bonds. In addition, owners of 2016 Senior Lien Bonds should consult their tax advisors with respect lo the state and local tax consequences of owning the 2016 Senior Lien Bonds. Under the applicable provisions of state or local income tax law, bond premium and original issue discount may give rise to taxable income at different times and in different amounts than they do for federal income tax purposes.

The opinions of Co-Bond Counsel and the descriptions of the tax law contained in this Official Statement are based on statutes, judicial decisions, regulations, rulings, and other official interpretations of law in existence on the date the 2016 Senior Lien Bonds are issued. There can be no assurance that such law or the inteipretation thereof will not be changed or that new provisions of law will not be enacted or promulgated at any time while the 2016 Senior Lien Bonds arc outstanding in a manner that would adversely affect the value or the tax treatment of ownership ofthe 2016 Senior Lien Bonds.

Appendix C
SUMMARY OF CERTAIN PROVISIONS OF THE AIRPORT USE AGREEMENTS
[This Page Intentionally Left Blank]
Appendix C
Summary of Certain Provisions of the airport Use agreements

The following is a summary of certain provisions of the Airport Use Agreements, to which reference is made for a complete statement of their provisions and contents. Certain words and terms used in this summary are defined in the Airport Use Agreements and have the same meanings in this summary, except as defined otherwise in this Official Statement. The Airport Use Agreements signed by the Airline Parties are substantially similar except for provisions relating to different exclusive use premises for each Airline Party and the termination or extension of certain other agreements of each Airline Party relating to O'Hare.
Term
The Airport Use Agreements became effective in 1983 (or upon their execution if later), were amended and restated in 1985, were amended again in 1996 and 2005, and expire on May 11, 2018.
Cost-Revenue Centers
The Airport Use Agreements group areas in O'Hare for various accounting purposes into six Cost-Revenue Centers. These are the Terminal Area, the Airfield Area, the International Terminal Area, the Terminal Support Area, the Fueling System and the Land Support Area (see "Land Support Area" below for a separate discussion). The purpose of the Cost-Revenue Centers is to allow for the calculation of Airport Fees and Charges in a manner that allocates such fees and charges among the Airline Parties (and, in the case of the Airfield Area, among non-Airline Parties as well) based on their usage of O'Hare. Accordingly, each of the Cost-Revenue Centers (except the Land Support Area) has allocated to it Revenues, Operation and Maintenance Expenses, Debt Service and certain fund deposit requirements.' Net deficits (that is, generally, the excess of Operation and Maintenance Expenses, Debt Service and fund deposits over Revenues) generated in any Fiscal Year in the Terminal Area and the Airfield Area Cost-Revenue Centers are paid by the Airline Parties in the form of Terminal Area Use Charges and Landing Fees, respectively. The net cost of the Fueling System Cost-Revenue Center is paid in the form of a separate Fueling System Fee. The Terminal Support Area and International Terminal Area Cost-Revenue Centers do not have specific fees or charges associated with them under the Airport Use Agreements. Instead, the net deficit (or net revenue) of each is calculated and then treated as a cost (or revenue) of the Terminal Area or the Airfield Area. It is not anticipated, however, that there will be a net deficit of the International Terminal Area under the Airport Use Agreements, because the net cost of the International Terminal Area is paid through fees and charges charged to the airlines that are signatories to the separate International Terminal Use Agreements.
Land Support Area
The Land Support Area is a geographic portion of O'Hare that presently consists of vacant land, certain air rights and facilities, such as air cargo (including mail), freight forwarding, aircraft maintenance, flight kitchens and fuel storage, and a site at O'FIare formerly occupied by the U.S. Military. The expenses of the Land Support Area are not included in the calculation of Airport Fees and Charges. Similarly, with certain exceptions, the income generated from facilities in the Land Support Area is not considered Revenues, and is not pledged as security for the payment of the Airport Obligations. There is currently no Debt Service allocated to the Land Support Area. One-half of the net revenues ofthe Land Support Area (excluding certain items) are deposited in the Revenue Fund for subsequent deposit in the Airport Development Fund described below under the subcaption "Special Funds." In addition, any net revenues of the Land Support Area allocable to any car or vehicle rental concessions and Airport


C-l

passenger public parking facilities located in the future on the former military site are to be deposited in the Revenue Fund and credited against Airport Fees and Charges.
Rentals, Fees and Charges

The Airport Use Agreements establish a $5 per square foot Terminal Area Rental for premises
leased to Airline Parties for their exclusive occupancy. Terminal Area Use Charges for such premises
also are calculated'on a square footage basis. Terminal Area Use Charges are based upon an allocation of
all'het costs attributable to 'the 'Terminal 'Area 'among 'Airline 'Parties leasing exclusive use premises in the
Terminal Area. ~ .... ^-.j a ... ..... ....... u,.

The net costs ofthe Fueling System Cost-Revenue Center are allocated among Airline Parties on the basis of fuel gallonage. Each Airline Party pays Fueling System Fees on the basis of a formula which reflects the ratio of its total gallonage to the total gallonage of all Airline Parties.
Landing Fees are calculated by first determiriirig the Net Cost of the Airfield Area, which consists
of portions of the following allocable to the Airfield Area: the sum of Operation and Maintenance,
Expenses, Debt Service, fund deposit requirements, and net deficit of the International Terminal' Area,
less the sum of Non-Use Agreement Revenues .(exclusive of landing fees payable by persons other than
Airline7P^es)"^d"net' revenues of the Intemaihwial Terminal, Area".' 'Beginning iri rates arid charges year
2006, the Net Cost of the'Airfield Airea is/.allocated among"Airline Patties'and users of the Airfield Area
that are not Airline Parties on'the basis 'of'the relative use ofthe Airfield Area by. such persons.' Such,
allocation of the Net Cost of the Airfield Area shall be based on the respective approved maximum landed
weight of aircraft of Airline" Parties landed during stich Fiscal Year and'the approved/maximum landed
weight of "all, aircraft of'other users .during"" siic^ fofpurppses of such allocation,'
the landed 'weight of certain' classes ,6f user's of the Airfield Area may be increased by certain premium factors "determined'by' thVCommissioner ,0'f Aviation from time to time. To the extent in any Fiscal Year Landing Fees, collected.from'userspf the Airfield Area other than Airline Parties.are in excess of the Net Cost of .the Airfield Area allpcated'to'such users for .that'Fiscal Year, such excess shall be applied in ftiturc years' in a manner that does riot, directly or indirectly, benefit any Airline Party.
General Commitment to Pay Airport Fees and Charges
The Airport Use Agreements provide that the aggregate of all rentals,'fees-and charges to be paid under all Airport Use Agreements by all Airline Parties shall be sufficient to pay for the net cost of operating, rhaintaining and developing O'Hare'(excluding the Land Support Area), including the satisfaction of all of the City's obligations to make deposits and payments under any ordinance or resolution authorizing Airport Obligations. Airport Fees and Charges not paid by a defaulting Airline Party, after appropriate collection efforts by the City and after exhaustion of certain funds available for that purpose, among others, are to be paid by all other Airline Parties as part of their Landing Fees as a result of the inclusion of such unpaid fees and charges in Operation and Maintenance Expenses of the Airfield Area.
Billing of Airport Fees and Charges
Not later than 30 days prior to the end of each Fiscal Year, the City furnishes the Airline Parties a projection of the Landing Fee Rate and Terminal Area Use Charges for the next Fiscal Year {"Projection of Fees and Charges"). The Landing Fees, Terminal Area Use Charges and Fueling System Fees for the next Fiscal Year are computed on the basis of the Projection of Fees and Charges, and Terminal Area Rentals are based on leased exclusive use premises. Not later than the 10th day of each month the City bills each Airline Party for the amount of its allocable share of Terminal Area Rentals and Use Charges

for the next month. The amount so billed is equal to 1/12th of each Airline Party's share of such rentals and charges for the Fiscal Year and is due on the first day of such next month. During each month the City also bills each Airline Party for Landing Fees payable for the preceding month; such Landing Fees are due within 30 days after the date of billing.
The Projection of Fees and Charges is adjusted at mid-year and Landing Fees, Terminal Area Use Charges and Fueling System Fees then may be adjusted accordingly. Within six months after the close of each Fiscal Year, a final audit is required to be prepared showing actual Landing Fees, Terminal Area Use Charges and Fueling System Fees for such Fiscal Year. Each Airline Party is entitled to a credit against subsequent billings (and in certain instances cash payments) for amounts paid in excess of the audited actual fees and charges, and is obligated to pay any deficiency along with its next monthly payment.

Capital Projects
The Airport Use Agreements contain as exhibits thereto descriptions of certain Capital Projects approved by the Airline Parties. The City was authorized in the Airport Use Agreements to issue Airport Obligations and include the Debt Service thereon in the calculation of Airport Fees and Charges without further consent or approval ofthe Airline Parties for all such Capital Projects, and also to (a) fund the cost of designing, constructing and equipping Capital Projects necessary to comply with any valid rale, regulation or order of any federal or state agency; (b) fund the cost of certain tenant improvements and certain relocation expenses; (c) fund insurance or condemnation award deficiencies; (d) refund or refinance Special Facility Revenue Bonds by agreement with Airline Parties; and (e) fund program and construction management costs and expenses relating to the implementation of the Airport Use Agreement.

INDEPENDENT AUDITORS' REPORT

The Honorable Rahm Emanuel, Mayor,
and Members of the City' Council: v - ¦¦•" ,¦: .¦
City of Chicago, Illinois
We have audited the accompanying basic financial statements of Chicago O'Hare International Airport ("O'Hare"), an enterprise fund of the City of Chicago, Illinois ("the City"), as of and for the years ended December 31, 2015 and 2014, and the related notes to the basic financial statements;'which collectively comprise O'Hare's basic financial statements as listed in the table of contents.
Management's Responsibility for the Basic Financial Statements
Management is responsible for the preparation and fair presentation of these financial statements in accordance with accounting principles generally accepted in the United States of America;, this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditor's Responsibility
Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.
An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor's judgment, including the assessment ofthe risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity's preparation and fair presentation ofthe financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity's internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of signi ficant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.
We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.
Opinion
In our opinion, the basic financial statements referred to above present fairly, in all material respects, the financial position of Chicago O'Hare International Airport as of December 31, 2015 and 2014, and the changes in its financial position, and its cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

Emphasis of Matter
As discussed in Note 1 to the basic financial statements, the basic financial statements referred to above present only Chicago O'Hare International Airport, an enterprise fund of the City, and do not purport to, and do not, present the financial position of the City as of December 31, 2015 and 2014, changes in its financial position, or where applicable, its cash flows, in conformity with accounting principles generally accepted in the United States of America. Our opinion is not modified with respect to this matter.
As discussed in Notes 1 and 12 to the basic financial statements, beginning net position at January 1, 2015 was restated due to the City's adoption of Governmental Accounting Standards Board (GASB) Statement No. 68, Accounting and Financial Reporting for Pensions—an amendment of GASB Statement No. 27; and, ending net position as of December 31, 2015 reflects changes in certain benefits and actuarial assumptions (Note 7). Our opinion is not modified with respect to these matters.
Other Matters

Required Supplementary Information
Accounting principles generally accepted in the United States of America require that management's discussion and analysis and the Schedule of Changes in the Net Pension Liability and Related Ratios, Schedule of Contributions, and Schedule of Other Postemployment Benefits Funding Progress, be presented to supplement the basic financial statements. Such information, although, not a part ofthe basic financial statements, is required by the Governmental Accounting Standards Board who considers it to be an essential part of financial reporting for placing the basic financial statements in an appropriate operational, economic, or historical context. We have applied certain limited procedures to the required supplementary information in accordance with auditing standards generally accepted in the United States, of America, which consisted of inquiries of management about the methods of preparing the information and comparing the information for consistency with management's responses to our inquiries, the basic financial statements, and other knowledge we obtained during our audit of the basic financial statements. We do not express an opinion or provide any assurance on the information because the limited procedures do not provide us with sufficient evidence to express an opinion or provide any assurance.
Other Information
Our audits were conducted for the purpose of forming an opinion on the basic financial statements that collectively comprise O'Hare's basic financial statements. The additional supplementary information and statistical information are presented for purposes of additional analysis and are not a required part of the basic financial statements. The additional supplementary information as listed in the table of contents is the responsibility of management and was derived from and relates directly to the underlying accounting and other records used to prepare the basic financial statements. Such information has been subjected to the auditing procedures applied in the audit of the basic financial statements and certain additional procedures, including comparing and reconciling such information directly to the underlying accounting and other records used to prepare the basic financial statements or to the basic financial statements themselves, and other additional procedures in accordance with auditing standards generally accepted in the United States of America. In our opinion, the additional supplementary information is fairly stated, in all material respects, in relation to the basic financial statements as a whole.

June 30, 2016
The statistical information has not been subjected to the auditing procedures applied in the audit of the basic financial statements, and accordingly, we do not express an opinion or provide any assurance on it.

Please read this discussion in conjunction with the Airport's basic financial statements and the notes to basic financial statements immediately following this section.

FINANCIAL HIGHLIGHTS!' ;< -.••-./- , . . f: ¦•

2015

» Operating revenues for 2015 increased by $704 (0.0%) compared to prior-year operating revenues.
Operating expenses before depreciation and amortization increased by $310,703 (62.8%) compared to 2014 primarily due to increases in pension cost resulting from the implementation of G ASB 68 and . salaries and wages.

2014
» Operating revenues for 2014 increased by$126,844 (17;7-%) compared to prior-year operating revenues. '
Operating expenses before depreciation and amortization increased by $68,958 (16.2%) compared to 2013 primarily due to increased salaries and wages, repairs and maintenance, and other operating expenses.
The Airport's total net position at December 31, 2014, was $1,460,084. This is an increase of $132,685 (9.9%) over total net-position at December 31, 2013.
Capital asset additions for 2014 were $346;671 principally due to land acquisition, buildings, runways and taxiway improvements and roadway rehabilitation.
OVERVIEW OF THE BASIC FINANCIAL STATEMENTS
This discussion and analysis is intended to serve as an introduction to the Airport's basic financial statements. The Airport is included in the City's reporting entity as an enterprise fund. The Airport's basic financial statements comprise the basic financial statements and the notes to basic financial statements. Tn addition to the basic financial statements, this report also presents additional and statistical information after the notes to basic financial statements.
The Statements of Net Position present all of the Airport's assets and liabilities using the accrual basis of accounting. The difference between assets and deferred outflows and liabilities and deferred inflows is reported as Net Position. The increase or decrease in net position may serve as an indicator, over time, whether the Airport's financial position is improving or deteriorating. However, the consideration of other non-financial factors, such as changes within the airline industry, may be necessary in the assessment of overall financial position and health of the Airport.
The Statements of Revenues, Expenses and Changes in Net Position present all current fiscal year revenues and expenses, regardless of when cash is received or paid, and the ensuing change in Net Position.

The Statements of Cash Flows report how cash and cash equivalents were provided and used by the Airport's operating, capital financing, and noncapital financing and investing activities. These statements present the cash received and disbursed, the net increase or decrease in cash and cash equivalents for the year and the cash and cash equivalents balance at year-end.
The Notes to Basic Financial Statements are an integral part ofthe basic financial statements; accordingly, such disclosures are essential to a full understanding of the information provided in the basic financial statements.
In addition to the basic financial statements, this report includes Additional Supplemental Information and Statistical Information. The Additional Supplemental Information section presents the debt service coverage calculations, and the Statistical Information section includes certain unaudited information related to the Airport's historical financial and non-financial operating results and capital activities.
FINANCIAL ANALYSIS
Landing fees, terminal area use charges, and fueling system charges are assessed to the various airlines throughout each fiscal year based on estimated rates. Such rates are designed to yield collections from airlines adequate to cover certain expenses and required debt service and fund deposits as determined under provisions of the Amended and Restated Airport Use Agreement and Terminal Facilities Lease and the International Terminal Use Agreement and Facilities Lease ("Use Agreements"). Incremental amounts due from the airlines arise when amounts assessed, based on the estimated rates used during the year, are less than actual expenses and required deposits for the year. Such incremental amounts due from airlines are included in amounts to be billed. Incremental amounts due to the airlines arise when amounts assessed, based on the estimated rates used during the year, exceed actual expenses and required deposits for the year. Such incremental amounts due to airlines are included in billings over amounts earned.

At December 31, 2015, the Airport's financial position continued to be strong with total assets and deferred outflows of $10,447,148, total liabilities and deferred inflows of $9,972,548, and net position of $474,600.

Current unrestricted assets increased.by $55,563 (26.4%) primarily due to increased accounts receivable and decreased cash and investments. The Airport's current ratio (current unrestricted assets/current unrestricted liabilities) at December 31, 2015 and 2014 was 1.00:1 and 1.20:1, respectively. Restricted and other assets increased by $5,679 (0.2%) primarily due to decreases in construction funds of $18,226 and capitalized interest funds of $ 14,555 and increases to debt service interest funds of $8,947 and Airport Development Funds of $33,143. Net capital assets increased by $217,841 (3.2%) due principally to capital activities of the Capital Improvement Program and the O'Hare Modernization Program (OMP) at the Airport.
The increase in current liabilities of $89,472 (51%) is mainly related to the increased accounts payable and accrued liabilities of $32,172 and increased amounts of advanced payments for terminal and hangar, rents of $5,427 offset by increased billings over amounts earned of $51,903.
Liabilities payable from restricted assets and noncurrent liabilities increased by $1,664,848 (20%) due primarily to the increase in pension liability.
Net position may serve, over a period of time, as a useful indicator ofthe Airport's financial position. As of December 31, 2015, total net position was $474,600, a decrease of $985,484 (67.5%) from 2()14primarily due to the impact ofthe implementation of GASB 68.
2014
Current unrestricted assets increased by $176 (0.08%) primarily due to increased accounts receivable and decreased cash and investments. The Airport's current ratio (current unrestricted assets/current unrestricted liabilities) at December 31, 2014 and 2013, was 1.19:1 and 1.20:1, respectively. Restricted and other assets decreased by $179,254 (6.6%) primarily due to decreases in construction funds of $209,904 and capitalized interest funds of $49,898 and increases to debt service interest funds of $28,008 and Airport Development Funds of $45,302. Net capital assets increased by $ 130,753 (1.9%) due principally, to capital activities ofthe Capital Improvement Program and the O'Hare Modernization Program (OMP) at the Airport.
The increase in current liabilities of $595 (0.3%) is mainly related to the increased billings over amounts earned of $12,963 offset in part by a decrease in accounts payable and accrued liabilities of $5,008 and decreased amounts of advanced payments for terminal and hangar rents of $4,817.

Liabilities payable from restricted assets and noncurrent liabilities decreased by $ 194,407 (2.4%) due primarily to the decrease in revenue bond payable.
Net position may serve, over a period of time, as a useful indicator of the Airport's financial position. As of December 31, 2014, total net position was $1,460,084, an increase of $132,685 (9.9%) from 2013.

7. PENSION PLANS
General Information about the Pension Plan
Plan Description. Retirement Benefit—Eligible O'Hare Fund employees participate in one of four single-employer defined benefit pension plans (Plans). These Plans are: the Municipal Employees'(Municipal); the Laborcrs'(Laborers') and Retirement Board Employees'; the Policemen's (Policemen's); and the Firemen's (Firemen's) Annuity and Benefit Funds of Chicago. Plans are administered by individual retirement boards of trustees comprised of City officials or their designees and of trustees elected by plan members. Each Plan issues a publicly available financial report that includes financial statements and required supplementary information that can be obtained at www.meabf.org ., www.labfchicago.org , www.chipabf.org and www.fabf.orgg .
Benefits Provided—The Plans provide retirement, disability, and death benefits as established by State law. Benefits generally vest after 10 years of credited service. Employees qualify for an unreduced retirement age minimum formula annuity based on a combination of years of service and age of retirement. Employees may also receive a reduced retirement age minimum formula annuity if they do not meet the age and service requirements for the unreduced retirement age annuity. The requirement of age and service are different for employees who became members before January 1, 2011, and those who became members on or after January 1, 2011. The annuity is computed by multiplying the final average salary by a percentage ranging from 2.2 percent to 2.5 percent per year of credited service. The final average salary is the employee's highest average annual salary for any four consecutive years within the last 10 years of credited service for participants who became members before January 1, 2011 and any eight consecutive years within the last 10 years of credited service for participants who became members on or after January 1, 20! 1.


-35 -

Benefit terms provide for annual adjustments to each employee's retirement allowance subsequent to the employees' retirement date. For participants who became members before January 1, 2011, the annual adjustments for Municipal and Laborers are 3.0 percent, compounded, and for Firemen's and Policemen's 3.0 percent, simple, for annuitants born before 1955 and 1.5 percent, simple, born in 1955 or later. For participants that first became members on or after January 1, 2011, the annual adjustments arc equal to the lesser of 3.0 percent and 50 percent of CPI-U ofthe original benefit.
Contributions—Historically, State law required City contributions at statutorily, not actuarially, determined rates. State law also requires covered employees to contribute a percentage of .their salaries. The City's contribution was calculated based on the total amount of contributions by employees to the Plan made in the calendar year two years prior, multiplied by 1.25 for the Municipal, 1.00 for the Laborers', 2.00 for the Policemen's, and 2.26 for the Firemen's. The City's contributions are budgeted in the same year as the applicable levy year for the property taxes funding the contributions. The City's contributions are then paid to the pension hinds in the following year (which is when the levied property taxes are collected and paid to the City by the Cook County Treasurer).
State law in effect at December 31, 2015 for the Policemen's and Firemen's Plans, known as Public Act 96-1495 (P.A. 96-1495), requires the City to significantly increase contributions to those Plans beginning in 2015. In each year, the City must contribute the amount needed for each Plan to achieve a 90% Funded Ratio by the end of 2040.
Public Act 99-0506 (P.A. 99-0506) was enacted on May 31, 2016. P.A. 99-0506 changed the funding requirements required by Public Act 96-1495, providing that the City make a fixed contribution amount for 2015 through 2019 which is significantly larger than contributions made prior to the adoption of P.A. 96-1495 but smaller than the contributions required under P.A. 96-1495. P.A. 99-0506 requires that the City's contributions are at actuarially determined rates beginning in 2020 and future funding be sufficient to produce a funding level of 90% by the year ended December 31, 2055 (instead of 2040 required by P.A. 96-1495). As this law was enacted subsequent to December 31, 2015, the measurement of the City's net pension liability as of December 31, 2015, was not impacted, since the liability was measured using the law in effect as of December 31, 2015. The City will be taking into consideration the impact of this new law when measuring the liability in 2016. The new law is expected to increase the City's net pension liability.
The City's contributions to Municipal and Laborer's are determined pursuant to the formulas set forth in the Illinois Pension Code (the Pension Code). Pursuant to Public Act 098-641 (P.A. 98-641), the City's contributions to Municipal and Laborer's were scheduled to increase beginning in 2015; however, in July 2015 the Circuit Court of Cook County determined P.A. 98-641 to be unconstitutional. As a result of such determination by the court, the provisions of the Pension Code governing the City's contributions to MEABF and LABF have reverted to the provisions in effect prior to the enactment of P.A. 98-641. Furthermore, in March 2016, the Illinois Supreme Court upheld the ruling made by the Circuit Court.

The contribution to all four pension plans from the Airport was $25.8 million for the year ended December 31, 2015.

Pension Liabiu'tics, Pension Expense, and Deferred Outflows of Resources and Deferred Inflows of Resources Related to Pensions
At December 31, 2015, the Airport reported a liability of $ 1,542 million for its proportionate share of the net pension liability. The net pension liability was measured as of December 31, 2015, and the total pension liability used to calculate the net pension liability was determined by an actuarial valuation as of


-36-

that date. The Airport's proportion of the net pension liability was determined based onbudgeted
Airport salaries within each corresponding pension plan. At December 31, 2015; the Airport's
proportion was 5.8 percent of the Municipal Plan, 6.2 percent of the Laborer's Plan, 1.3 percent ofthe
Policemen's Plan and 4.9 percent of the Firemen'-s Plan: •>. ••• -|910|Changes in Benefits and Actuarial Assumptions: As discussed above, P.A. 98-0641 was determined to
be unconstitutional resulting in changes in the discount rate caused by a change in the required funding
policy and changes in benefits for the participants ofthe Municipal and Laborers pension'plans,1 which
include restoring full automatic annual increase and changes, in the retirement age for certain
participants.'' : ' * '•• •* ' ' ¦ ''¦ ' ¦ ¦¦ ¦';-v>
The change in the discount rate assumption increased the Airports'allocated net pension liability by $507.3 million.for Municipal and $73.1 million for Laborers'. This impact is.being.amortized over a five year period for Municipal and a four year period for Laborers'. The change in ibenefits increased the Airport's allocated share ofthe net pension liability by $124.6 million for. Municipal and $23:9 million for Laborers'. This impact is recognized as a portion of 2015 pension expense in its entirety. For the year ended December 31, 2015, the Airport recognized pension expense of $339.5 million. ¦'¦
At December 31, 2015, the Airport reported deferred outflows of resources of $487.9 million arid deferred inflows of resources of $8.6 million related to pensions from the following sources: '

Mortality rates were based on the RP-2000 Health Annuitant Mortality Table for Males or Females, as appropriate for Municipal, Laborers' and Firemen's and RP-2014 for Policemen's.

The mortality actuarial assumptions used in the December 31, 2015 valuation were adjusted based on the results of actuarial experience study for the following periods:

The long term expected rate of return on pension plan investments was determined using the building-block method in which best-estimate ranges of expected future real rates of return (expected returns, net of pension plan investment expense and inflation) are developed for each major asset class. These ranges are combined to produce the long-term expected rate of return by weighting the expected future real rates of return by the target asset allocation percentage and by adding expected inflation. The target allocation and best estimates of arithmetic real rates of return for each major asset class are summarized in the following table:

Discount Rate
Municipal—The discount rate used to measure the total pension liability was 3.73%. This Single Discount Rate was based on an expected rate of return on pension plan investments of 7.5 percent and a municipal bond rate of 3.6 percent (based on the Bond Buyer 20- Bond Index of general obligation municipal bonds as of December 31, 2015).The projection of cash flows used to determine the discount rate assumed member contributions will be made at the current contribution rate and that employer contributions will be made at the 1.25 multiple of member contributions from two years prior. For this purpose, only employer contributions that are intended to fund benefits of current plan members and their beneficiaries are included. Projected employer contributions and contributions from future plan members that are intended to fund the service costs of future plan members and their beneficiaries are not included. Based on those assumptions, the pension plan's fiduciary net position was not projected to be available to make all projected future benefit payments of current plan members. The projected benefit payments through 2023 were discounted at the expected long-term rate of return. Starting in 2024, the projected benefit payments were discounted at the municipal bond rate. Therefore, a single equivalent, blended discount rate of 3.73% was calculated using the long-term expected rate of return and the municipal bond index.
Laborers'—A Single Discount Rate of 4.04 percent was used to measure the total pension liability. This Single Discount Rate was based on an expected rate of return on pension plan investments of 7.5 percent and a municipal bond rate of 3.6 percent (based on the Bond Buyer 20- Bond Index of general obligation municipal bonds as of December 3 1, 2015).The projection of cash Hows used to determine this Single Discount Rate assumed that plan member contributions will be made at the current contribution rate and


-40 -

that employer contributions will be made at rates equal to the difference between statutory contribution rates and the member rate. Based on these assumptions, the pension plan's fiduciary net position and future contributions were sufficient to finance the benefit payments through the year 2027. As a result, the long-term, expected rate of return on pension plan investments-was applied to projected benefit payments through the year 2027, and the municipal bond rate was applied to all benefit.payments after that date.
Policemen's—A Single Discount Rate of 7.15 percent was used to measure the total pension liability. This Single Discount Rate was based on an expected rate of-return on pension plan investments of 7.5,percent and a municipal bond rate,of 3.6,percent (based on the. Bond Buyer 20- Bond Index of general obligation municipal bonds as of December 31, 2015).The projection of cash flows used to determine this Single Discount Rate assumed that plan member contributions will be made at the current contribution rate and that employer contributions will be made at rates equal to the difference between statutory contribution rates and the member rate. Based-.on these assumptions, the pension plan's fiduciary net position and future contributions were sufficient to finance the benefit payments through the year 2063. As a result, the long-term expected rate of return on pension plan investments was applied to projected benefit payments through the year 2063, and the municipal bond rate was applied to all benefit payments after that date.
Firemen's—A Single Discount Rate of 7.16 percent was used to measure the total pension liability. This Single Discount Rate was based on an expected rate of return on pension plan investments of 7.5 percent and a municipal bond rate of 3.6 percent (based on the Bond Buyer 20- Bond Index of general obligation municipal bonds as of December 31, 2015).The projection of cash flows used to determine this Single Discount Rate assumed that member contributions will be made at the current contribution rate and that employer contributions will be made at rates equal to the difference between statutory contribution rates and the member rate. Based on these assumptions, the Plan's fiduciary net position and future contributions were sufficient to finance future benefit payments only through the year 2061. As a result, the long-term expected rate of return on pension plan investments was applied to projected benefit payments through the year 2061, and the municipal bond rate was applied to all benefit payments after that date.

Actuarial Method and Assumptions—For the Pension Funds' subsidies, the actuarial valuation for the fiscal year ended December 31, 2015 was determined using the Entry Age Normal actuarial cost method. Projections of benefits for financial reporting purposes are based on the substantive plan (the plan understood by the employer and plan members) and included the types of benefits provided at the time of each valuation and the historical pattern of sharing of benefit costs between the employer and plan members to that point. The actuarial method and assumptions used include techniques that are designed to reduce the effects of short term volatility in actuarial accrued liabilities and the actuarial value of assets, consistent with the long term perspective of the calculations.

Other PostEmploymcnt Bencfits-^City Obligation
Up to June 30, 2013, the annuitants who retired prior to July 1, 2005 received a 55 percent subsidy from the City and the annuitants who retired on or after July 1, 2005 received a 50, 45, 40 and zero percent subsidy from the City based on the annuitant's length of actual employment with the City for the gross cost of retiree health care under a court approved settlement agreement, known as the "Settlement Plan." The pension funds contributed their subsidies of $65 per month for each Medicare eligible annuitant and $95 per.month for each Non-Medicare eligible annuitant to their gross cost. The annuitants contributed a total of $104.4 million in 2015 to the gross cost of their retiree health care pursuant to premium amounts set forth in the below-referenced settlement agreement.
The City subsidized a portion of the cost (based upon service) for hospital and medical coverage for eligible retired employees and their dependents based upon a settlement agreement entered in 2003 and which expired on June 30, 2013.
On May 15, 2013, the City announced plans to, among other things: (i) provide a lifetime.healthcare plan to former employees who retired before August 23, 1989 with a contribution from the City of up to 55% ofthe cost of that plan; and (ii) beginning July 1, 2013, provide employees who retired on or after August 23, 1989 with healthcare benefits in a new Retiree Health Plan (Health Plan), but with significant changes to the terms including increases in premiums and deductibles, reduced benefits and the phase-out of the Health Plan for such employees by December 31, 2016.
The cost of health benefits is recognized as an expenditure in the accompanying financial statements as claims are reported and are funded on a pay-as-you-go basis. In 2015, the net expense to the City for providing these benefits to approximately 22,697 annuitants plus their dependents was approximately $44 million.
Plan Description Summary—The City of Chicago was party to a written legal settlement agreement outlining the provisions of the Settlement Plans, which ended June 30, 2013. The Health Plan provides for annual modifications to the City's level of subsidy. It is set to phase out over three years, at which the Health Plan, along with any further City subsidy, will expire by December 31, 2016, for all but the group of former employees (the Korshak class of members) who retired before August 23, 1989, who shall have lifetime benefits. Duty Disabled retirees who have statutory pre-63/65 coverage will continue to have fully subsidized coverage under the active health plan until age 65.
The provisions ofthe Health Plan provide in general, that the City pay a percentage ofthe cost (based upon an employee's service) for hospital and medical coverage to eligible retired employees and their dependents for the specified period, ending December 31, 2016. The percentage subsidies were revised to reduce by approximately 25 percent of 2013 subsidy levels in 2014 and 50 percent of 2013 subsidy levels in 2015, and 75 percent of 2013 subsidy levels in 2016.

In addition, State law authorizes the four respective Pension Funds (Policemen's, Firemen's, Municipal Employees', and Laborers') to provide a fixed monthly dollar subsidy to each annuitant who has elected coverage under any City health plan through December 31, 2016. After that date, no Pension Fund subsidies are authorized. The liabilities for the monthly dollar Pension Fund subsidies contributed on behalf of annuitants enrolled in the medical plan by their respective Pension Funds arc included in the Net Pension Obligation ("NPO") actuarial valuation reports ofthe respective four Pension Funds under GASB 43.
Special Benefits under the Collective Bargaining Agreements (CBA)—Under the terms of the collective bargaining agreements for the Fraternal Order of Police (FOP) and the International


-46 -

Association of Fire Fighters (IAFF), certain employees-who retire after attaining age 55 with the required years of service are permitted to enroll themselves and their dependents in the healthcare benefit program offered to actively employed members. They may keep this coverage until they reach the age of Medicare eligibility. These retirees do not contribute towards the'cost of coverage, but the Policemen's Fund-contributes $95 per month towards coverage for police officers; the:-Firemen's Fund does not contribute.
Both of these agreements which provide pre-65 coverage originally expiredat June 30, 2012. These benefits have been renegotiated to continue^ through 2016 or June'30, 2017, depending on bargaining unit agreements. This valuation assumes that the GBA special benefits, except for those who will have already retired as of December 31, 2016, will cease on December 31, 2016 or June 30, 2017, depending on bargaining unit agreements. •
Funding Policy—No assets are accumulated or dedicated to funding the retiree health:plan benefits.
Annual OPEB Cost and Net OPEB Obligation—The City's annual.other post-employment benefit
(OPEB) cost (expense) is calculated based on thcannual required contribution of the employer (ARC).
The^ARC (Annual Required Contribution) represents adcvel of funding that,! if paid^oni an ongoing basis,
is projected to cover the normal cost each year and to amortize any unfunded actuarial liabilities over a

Funded Status and Funding Progress—As of January 1, 2015, the most recent actuarial valuation' date, the actuarial accrued liability for benefits was $780.6 million all of which was unfunded. The covered payroll (annual payroll of active employees covered by the plan) was approximately $2,488.0 million and the ratio ofthe unfunded actuarial accrued liability to the covered payroll was -31.4 percent.

Actuarial valuations of an ongoing-plan involve estimates of the value of reported amounts and assumptions about the probability of occurrence of events far into the future. Examples include assumptions about future employment, mortality, and the healthcare cost trend. Amounts determined regarding the funded status of the :p I an-and-thc annual required contributions of the employer are subject to continual revisions as the results are compared.with past expectations and new estimates, are made about the future.

Actuarial Method and Assumptions—Projections of benefits for financial reporting purposes are based on the substantive plan (the plan understood by the employer and plan member's) and-included the types of benefits provided at the time of each valuation and the historical pattern of sharing of benefit costs between the employer and plan members'to that point. The actuarial method and'assumptions used include techniques that are designed to reduce the effects of short term volatility in actuarial accrued liabilities and the actuarial value of assets, consistent with the long term perspective ofthe calculations.
For the Health Plan benefits (not provided by the Pension Funds), the entry age normal actuarial cost method was used. The actuarial assumptions included an annual healthcare cost trend rate of 8.0% initially, reduced by decrements to an ultimate rate of 5.0% in 2026. The range of rates included a 3.0% inflation assumption. Rates included a 2.5% inflation assumption. The plan has not accumulated assets and does not hold assets in a segregated trust. However, the funds expected to be used to pay benefits are assumed.to be invested for durations which will yield an annual return rate of 3.0%. The remaining Unfunded Accrued Actuarial Liability is being amortized as a level dollar amount over ten years. The benefits include the provisions under the new Health Plan, which will be completely phased-out by December 31, 2016, except for the Korshak category, which is entitled to lifetime benefits. Also included in the Non-CBA benefits are the duty disability benefits under the active health plan payable to age 63/65.

For the Special Benefits under the CBA for Police and Fire, the renewed contracts' expiration dates of June 30, 2016 (for Police Captains, Sergeants and Lieutenants) and June 30, 2017 for all other Police and Fire are reflected, such that liabilities are included only for payments beyond the end ofthe calendar year of contract expiration on behalf of early retirees already retired and in pay status as of December 31 of the expiration year of the contract. The entry age normal method was selected. The actuarial assumptions included an annual healthcare cost trend rate of 8.0% in 2014, reduced by decrements to an ultimate rate of 5.0% in 2026. Rates included a 2.5% inflation assumption. The plan has not accumulated assets and does not hold assets in a segregated trust. The funds expected to be used to pay benefits are assumed to be invested for durations which will yield an annual return rate of 3.0%.

Included in operating expenses arc reimbursements to the general fund ofthe City for services provided by other City departments, employee fringe benefits, and certain payments made on behalf of the Airport. Such reimbursements amounted to $86.1 million and $72.8 million in 2015 and 2014, respectively.

10. COMMITMENTS AND CONTINGENCIES
The Airport has certain contingent liabilities resulting from litigation, claims, and commitments incident to its ordinary course of business. Management expects that the final resolution of these contingencies will not have a material adverse effect on the financial position or results of operations of the Airport.

RE: City of Chicago, Chicago O'Hare International Airport
General Airport Senior Lien Revenue Refunding Bonds, Series 2016A (AMT) General Airport Senior Lien Revenue Refunding Bonds, Series 2016B (Non-AMT) General Airport Senior Lien Revenue Refunding Bonds, Series 2016C (Non-AMT) General Airport Senior Lien Revenue Bonds, Series 2016D General Airport Senior Lien Revenue Bonds, Series 2016E General Airport Senior Lien Revenue Bonds, Series 2016F

Dear Ms. Evans:
Ricondo & Associates, Inc. (R&A) is pleased to present this Report of the Airport Consultant (the Report) for inclusion as Appendix E in the Official Statements for the 2016 Bonds, defined herein and described in detail in this Report. The 2016 Bonds, comprised of the 2016 Refunding Bonds and 2016 New Money Bonds, described herein, will be issued pursuant to an ordinance adopted by the Chicago City Council on September 14, 2016 (the Bond Ordinance) and the Master Indenture of Trust securing Chicago O'Hare International Airport Senior Lien Obligations dated as of September 1, 2012 (the Senior Lien Master Indenture) between the City of Chicago (the City) and U.S. Bank National Association, Chicago, Illinois (the Trustee), as supplemented by the Supplemental Indentures from the City of Chicago (the City) to the Trustee. The Senior Lien Master Indenture, as supplemented by the Supplemental Indentures, and as it may be amended and supplemented from time to time in accordance with its terms, is herein referred to as the Senior Lien Indenture.
The 2016 Bonds will be secured under the Senior Lien Indenture by a lien on and pledge of all Revenues and in some cases Other Available Moneys and will be payable from amounts that may be withdrawn from the Debt Service Fund created under the Senior Lien Indenture, as described in the Report.
The City will use the proceeds from the sale of the 2016 Refunding Bonds, together with other available funds, to:
refund certain outstanding Airport Obligations to generate debt service savings,
fund the related reserve requirements for the 2016 Refunding Bonds, and

(iii) pay costs and expenses incidental thereto and to the issuance of the 2016 Refunding Bonds.

The City will use the proceeds from the sale of the 2016 New Money Bonds, together with other available funds, to:
pay the costs of the-2016 Projects, as herein defined
fund the related reserve requirements for the 2016 New Money Bonds,
fund capitalized interest on'a portion ofthe 2016 New Money Bonds, and
pay costs and expenses incidental thereto and to the issuance of the 2016 New Money Bonds.

Unless otherwise defined herein, all capitalized terms in this Report are used as defined in the Official Statements for the 2016 Bonds and/or the Senior Lien Indenture.
This Report presents the analysis undertaken by R&A to demonstrate the ability of the City to comply with the requirements of the Senior Lien Indenture for Fiscal Years (FYs) 2016 through 2025 (the Projection Period) based on the assumptions regarding the planned issuance of the 2016 Bonds established by the City through consultation with its financial advisors, underwriters, and the financing team. In developing its analysis, R&A has reviewed historical trends and formulated projections based on the assumptions put forth in this Report, which have been reviewed by the City, regarding the ability of the Air Trade Area (as defined herein) to generate demand for airline service at Chicago O'Hare International Airport (the Airport), the amount of airline service and passenger activity at the Airport, and the generation of Revenues and Other Available Moneys at the Airport through the Projection Period. The Report is organized as follows:
Summary of Findings
. Chapter 1: The 2016 Bonds
Chapter 2: The Airport Facilities, Capital Program, and 2016 Projects
Chapter 3: Demographic and Economic Analysis
Chapter 4: Air Traffic
Chapter 5: Financial Analysis
IE-4]
On the basis of the analysis set forth in this Report, R&A is of the opinion that the Revenues and Other Available Moneys generated each year of the Projection Period are expected to be sufficient to comply with the Rate Covenants established in the Senior Lien Indenture, and that the resulting projected airline

costs should remain reasonable. Although summary information is provided, a complete understanding of the justification for our conclusion cannot be attained without reading the Report in its entirety.
Founded in 1989, R&A is a full-service aviation consulting firm providing airport physical and financial planning services to airport owners and operators, airlines, and federal and state agencies. R&A has prepared Reports ofthe Airport Consultant in support of over $26 billion of airport related revenue bonds since 1996. R&A is not registered as a municipal advisor under Section 15B of the Securities Exchange Act of 1934. R&A is not acting as a municipal advisor and has not been engaged by the City to provide advice with respect to the structure, timing, terms, or other similar matters concerning the issuance of municipal securities. The assumptions regarding such matters included in this Report were provided by the City or the City's financial advisors or underwriters, or, with the City's approval, were derived from general, publicly available data approved by the City. R&A owes no fiduciary duty to the City. The City should discuss the information and analysis contained in this Report with internal and external advisors and experts that the City deems appropriate before taking any action. Any opinions, assumptions, views, or information contained herein are not intended to be, and do not constitute, "advice" within the meaning of Section 15B of the Securities Exchange Act of 1934.
The techniques and methodologies used by R&A in preparing this Report are consistent with industry practices for similar studies in connection with airport revenue bond sales. While R&A believes that the approach and assumptions used in this Report are reasonable, some assumptions regarding future trends and events detailed in this Report, including, but not limited to, the implementation schedule and the projections of passenger activity and financial performance, may not materialize. Therefore, actual performance will likely differ from the projections set forth in this Report and the variations may be material. In developing its analysis, R&A used information from various sources, including the City, the underwriters, the financial advisors, federal and local governmental agencies, and independent private providers of economic and aviation industry data, as identified in the notes accompanying the related tables and exhibits in this Report. R&A believes these sources to be reliable, but has not audited the data and does not warrant their accuracy. The analysis presented is based on conditions known as of the date of this letter. R&A has no obligation to update this Report on an ongoing basis.

Sincerely,

RICONDO & ASSOCIATES, INC.

The Airport Facilities, Capital Program, and 2016 Projects

The Airport is the largest commerciaL-service airport.serving .Chicago and the.surrounding region. Its primary facilities consist of the airfield, terminal area, rental car facilities, air cargo areas, maintenance/airport support areas, and surface access/parking areas. The airfield consists of eight active runways; the terminal area consists of four terminal buildings with a total of 189 gates. The Airport's airfield, terminal area, and other facilities are described in Chapter 2 of this Report.
The City has been undertaking major capital planning initiatives at the Airport, including airfield and facility development, while also maintaining a 5-year Capital Improvement Program (CIP) to address the Airport's ongoing capital needs. The Airport's capital program includes the O'Hare Modernization Program (OMP) Airfield Projects, the 5-year (2016-2020) CIP, and other recently announced capital projects, as described briefly in this section and further described in Chapter 2 of this Report.
OMP Airfield Projects2 are changing the airfield from a layout with intersecting runways to a modern parallel runway system. The OMP, which includes the construction of one new runway, the relocation of three existing runways and the extension of two existing runways, is being undertaken in phases that began in 2005. To date, three of the four runways have been completed and one of the two runway extensions has been completed. The Airport has experienced a reduction in operational delays and an increase in airfield capacity with the completion of the OMP projects. The remaining OMP Airfield Projects include one runway (under construction), and an extension to an existing runway, which is expected to further reduce delays and increase capacity. Funding for the OMP Airfield Projects has been undertaken in phases. OMP Phase 1, a $3.21 billion project, included two runways and an extension and was completed in 2013. A $1.07 billion funding agreement with the Airline Parties for OMP Phase 2A included a runway and enabling projects for a future runway. This


The OMP also includes the construction of a terminal complex on the west side of the Airport The Chicago Department of Aviation has indicated it will pursue the Western Terminal Complex only as demand dictates the need for the facilities, and costs for the Western Terminal Complex have not been included in the financial analysis included in Chapter 5 of this Report. For additional information on terminal facility plans, see Section 2 2.1. -

-phase is fully- funded;-the;runwayrpro|ect.was.comply 2015 and the remaining, projects
are anticipated to remain within budget. A $1.3 billion infrastructure plan that includes another OMP runway was agreed upon in. a funding agreement among United.Airlines (United) and American Airlines (American); and the City in January 2016 and Majority-In-Interest funding authority, for the plan was approved by the Airline Parties in February 2016. The plan, which includes Runway 9C-27C,
. an OMP Airfield Project, and additional airfield improvements not part of the remaining OMP Airfield Projects, which include a centralized deicing pad, a cross-field taxiway system and relocation of Taxiways A and B; are expected to be funded with proceeds from the 2016 New Money Bonds, and is
. expected tq.be completed by December 2020, For purposes of the financial analysis included in Chapter 5 of this Report, additional future General Airport Revenue. Bonds (GARBs) have been included for funding of the construction of the remaining OMP runway extension project.
2016-2020 CIP includes ongoing repair and maintenance and other capital projects, such as the construction of .a> Mujtimpdal Facility, .which jncludes/.a consolidated, rental, car and, public parking facility and an extension ofthe Airport Transit System (ATS); airfield improvements associated with the third-party construction of a cargo facility in the northeast area of the Airport; the expansion of the Airport Maintenance Complex; additions and modifications to terminal facilities, including an ¦ expansion of the Terminal 5 Federaklnspection Station; safety and security projects, including an inline baggage system in'Concourse1 L and checked baggage inspection station optimization in-Terminal 1; and noise mitigation.:The;cost of the^2016-2020^GIP ^' approximately $1t78 .billion and includes planning and implementation costs. The 2016-2020 CIP is expected to ¦• be funded through a combination of federal grants and loans (Federal Aviation Administration [FAA] Airport Improvement Program [AIP] entitlements, FAA AIP discretionary .grants, Transportation Security Administration [TSA] grants, U.S Department of Transportation [U.S. DOT] loan), Customer Facility Charge (CFC) pay-as-you-go, proceeds from previously issued, bonds, assumed proceeds from future bond issuances, and other Airport funds. The City estimates that approximately, $773.3 million of 2016-2020 CIP project expenditures is expected to be funded using proceeds from future bonds; these future bond issuances are also incorporated into the financial analysis of this Report; No 2016-2020 CIP projects are anticipated to be funded with proceeds from the 2016 New Money Bonds.
Other Recently Announced Capital Projects include an expansion of Terminal 5 and Concourse L in Terminal 3. These projects will add gates at the domestic and international terminals, are expected to be completed over the next two to three years, and do not require airline approval. The expansion of Terminal 5 is expected to be funded using proceeds from PFC Revenue Bonds anticipated to be issued in 2017, discussed in Section 5.4.1 of this Report. Additional long-term terminal development and redevelopment options (Terminal Area Plan) are being evaluated in coordination with airline representatives to address long-term terminal capacity. A redevelopment of the existing terminal hotel and the construction of two new hotels on Airport property are also planned and expected to be complete between 2020 and 2022. The feasibility of a future express rail third-party project connecting the Airport to the central business district is currently being studied. The expansion of Concourse L is under construction and is being funded directly by American Airlines. The $266.8 million Terminal 5 Expansion is anticipated to be funded by Passenger Facility Charge (PFC) Revenue (pay-as-you-go and PFC Revenue Bonds) and Airport discretionary funds. The Terminal Area Plan (TAP) is still in preliminary conceptual planning and discussion phases, and while funding for the TAP

is expected to include future bond proceeds with debt service payable during the Projection Period, due to the uncertainty of timing and project costs the financial analysis in Chapter 5 of this Report does not include debt service associated with the funding of the TAP. The total investment for the three hotel development projects is estimated to be approximately $350 million and is planned to be funded by-a-special-facility loan(s) backed by hotel revenues. Because a detailed funding plan does not yet exist for the hotel development, the financial analysis in this Report does not include future funding of this project.

The 2016 Projects
The 2016 Projects will be funded with proceeds from the 2016 New Money Bonds and include the construction of Runway 9C-27C and enabling projects, including airline facility relocation; a centralized deicing pad; and a cross-field taxiway system and relocation of Taxiways A and B. The 2016 Projects total approximately $1.3 billion, of which approximately $1.0 billion is expected to be funded with proceeds from the 2016 New Money Bonds. PFC Revenue and Grant Receipts from a FAA Letter.of Intent (LOI) Grant, both used on a pay-as-you-go basis, are anticipated to fund the portions of the 2016 Projects not funded with the 2016 New Money Bonds. Airline Party approval has been received for the 2016 Projects.
Additional information on the Airport and projects included in its capital program is provided in Chapter 2 of this Report.

Demographic and Economic Analysis

The demand for air transportation is, to a degree, dependent upon the demographic and economic characteristics of an airport's air trade area. This relationship is particularly true for origin and destination (O&D) passenger traffic, which has historically accounted for approximately 50 percent of demand at the Airport (with connecting passengers accounting for the remaining 50 percent). Demand for airline travel at the Airport, therefore, is influenced by the local characteristics of the area served, along with individual airline decisions regarding service in support of connecting activity.
The Airport's Air Trade Area has a large, diverse economic base that supports business and leisure travel. Projected economic variables indicate that the Air Trade Area will remain a destination that attracts both business and tourist visitors, positively affecting the demand for future inbound airline travel. Projected Air Trade Area economic variables further support the continued growth of local outbound passengers. Table S-2 presents selected 2015 and 2025 economic figures for the Air Trade Area and for the United States, as projected by Woods & Poole Economics, Inc.

Additional information on the demographic and economic characteristics of the Air Trade Area is provided in Chapter 3.

Air Traffic

Chicago's location along the heavily traveled east/west air routes and its large population base make it a natural location for airline hubbing operations. United and American3, two of the world's largest airlines in terms of revenue passenger miles, operate major connecting hub facilities at the Airport. The City is also served by Chicago Midway International Airport, a major airport for Southwest Airlines. Together the two airports provide a complementary, three-hub airport system for the area's O&D passenger base.
The Airport consistently ranks among the busiest airports in the world. According to preliminary data from Airport Council International, in 2015 the Airport was 4th busiest in terms of passenger volume (second in the United States behind Hartsfield Atlanta International Airport), the 2nd busiest in terms of aircraft movements, and the 17th busiest in terms of cargo tonnage (6th in the United States) Based on U.S. DOT survey data, the




In December 2013, American and US Airways merged under the same parent corporation. The FAA granted American a single operating certificate on April 8, 2015. References to "American" in this Report reflect the combined American/US Airways unless otherwise designated.


Report of the Airport Consultant

CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT



Chicago market4 was ranked 4th in the nation in terms of domestic O&D passengers for the year 2015— following the New York,5 Los Angeles,6 and San Francisco7 markets.
The Airport served approximately 76.9 million enplaned and deplaned passengers in 2015, an increase of 9.8 percent from the previous year. Through thei first eight months of 2016, enplaned passenger activity at the Airport has increased 2.5 percent from the same period in 2015.
In the 12 months ended August 2016, a total of 21 United States flag carriers, 36 foreign flag carriers, 5 nonscheduled charter airlines, and 22 all-cargo airlines provided service at the Airport. In 2015, United and American, combined with their affiliates, accounted for 44.2 percent and 35.8 percent, respectively, of enplaned passengers at the Airport. In addition, other significant United States airlines serving the airport include Alaska Airlines and Delta Air Lines, as well as low-cost airlines Frontier Airlines, JetBlue, Spirit Airlines, and Virgin America. Low-cost airlines have been a significant source of new seat capacity at the Airport. Low-cost airlines increased scheduled seat capacity by 21.1 percent in 2014 and by 65.4 percent in 2015, and they will increase scheduled seat capacity by another 3.8 percent in 2016. Between 2006 and 2014, O&D passenger traffic at the Airport decreased at a compound annual rate of 0.7 percent. However, more recent growth resulted.in a 17.4 percent increase in O&D traffic in,.2015,. Between 2006 and 2015, the airlines' domestic O&D revenue at the Airport grew at a compound annual growth rate (CAGR) of 2.3 percent, reflecting strong revenue growth by the airlines serving the Airport.
Forecasts of aviation demand (i.e., enplaned passengers, aircraft operations, and landed weight) were developed considering:
Historical activity, including passenger volume and revenue trends at the Airport and across the industry;
Recent trends and future forecasts of local and national socioeconomic factors; and
Anticipated use of the Airport by American, United, low-cost airlines, and other airlines.

Passenger activity is forecasted to grow at a CAGR of 0.8 percent from the base year of 2015 through the end ofthe Projection Period in 2025.

Financial Analysis

R&A completed an analysis that demonstrates the ability of the City to comply with the requirements of the Airport Use Agreement and Senior Lien Indenture in each year ofthe Projection Period.
The current Airport Use Agreement expires in May 2018. For purposes of the financial analysis in this Report, the existing residual rate-making methodology defined in the Airport Use Agreement is assumed to continue throughout the Projection Period. However, the'rate-setting methodology could be different following the expiration of the current Airport Use Agreement in 2018. Even with a different methodology, the City's obligations to bond holders set forth in the Senior Lien, Indenture, including the dbligatiph to set rates and charges sufficient to meet the Rate Covenants, remain. Based on the financial analysis in Chapter 5 of this Report, R&A is of the opinion that the Net Revenues Available for Senior Lien Coverage generated by the Airport in each year of the Projection Period are expected to'be sufficient to comply with'the Additional Bonds Tests and the Rate Covenants established in the Senior Lien Indenture.
The GARB'debt serviceincluded1 in the financial analysis reflects debt service on outstanding GARBs, the 2016 New Money Bonds, and1 future-GARBs necessary'for funding the OMP Airfield Projects and 2016-2020 CIP capital projects described in Chapter 2. Future PFC Revenue Bbrids,jahticip'ated to be issued in 2017 to fund a portion of Terminal 5 Expansion project and to potentially refund certain outstanding PFC Revenue Bonds, are described in Section 5.4.1. of this'Report.
In combination, the 2016 New Money Bonds and future GARBs assumed in the financial analysis reflect the following capital project funding assumptions;
approximately $1.3 billion, for remaining OMP Airfield Projects, including. $963.5 million for Runway 9C-27C funded with proceeds from the 2016 New Money Bonds and $361.4 million for the extension of Runway 9R-27L' funded with future GARB proceeds,
approximately $304.3 million for additional airfield improvements, including $118.0 million for the centralized deicing pad and $186.3 million for cross-field taxiway system and relocation of Taxiways A and B, both funded with proceeds from the 2016 New Money Bonds, and
approximately $773.3 million for the 2016-2020 CIP projects funded with future GARB proceeds.

Results of the financial analysis are as follows:
Operation and maintenance (O&M) Expenses are projected to increase to approximately $857.1 million, excluding Land Support Area expense, in FY 2025, representing a CAGR of 5.4 percent between FY 2016 and FY 2025. This increase is based on the type of expenses anticipated, the fulfillment of certain assumed City pension contributions described in Section 5.2.2, expectations of future inflation rates (assumed to be 3.0 percent annually) and projected increases to O&M Expenses associated with the completion of OMP Airfield Projects.
Non-Signatory and Non-Airline Revenues are projected to increase from $386.3 million in 2016 to $495.3 million in 2025, a CAGR of 2.8 percent. Non-Airline Revenues include revenues from the Chicago International Carriers Association Terminal Equipment Corporation (CICA TEC); and from

Report of the Airport Consultant

CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT



concessions, including automobile parking, automobile rentals, and concessions in the domestic and international terminals. These revenues are discussed in Section 5.3.2.
Net Debt Service (including debt service on the 2016 Bonds and projected debt service on future bonds necessary to complete"the OMP Airfield Projects and 2016-2020 CIP), net of capitalized interest, PFC Revenues, and Grant Receipts used to pay debt service, is projected to be approximately $423.4 million in FY 2016, then projected to increase throughout the Projection Period to a peak of approximately $533.9 million in 2022, and then projected to decrease slightly to $531.4 million in 2025.
The airline cost per enplanement (CPE) at the Airport is estimated to be approximately $17.49 in 2016 and is projected to increase to $25.38 in 2025 (which equates to approximately $19.45 in 2016 dollars).
The projected Airport user fees are evaluated in this analysis to be reasonable based on the expectation that these fees will not deter forecasted demand for air traffic at the Airport as airlines continue to deploy capacity to airports based on available resources. The projected Airport user fees in this analysis are deemed to be reasonable based on the following combination of factors;
large population and strong economic base,
attractive geographical location,
important hub for United and American, and
increases in debt are associated with capital projects that allow for growth.

Table S-3 presents the Debt Service coverage ratio projected for Senior Lien Bonds from 2016 through 2025. As contained in the Senior Lien Indenture:
The City covenants that it will fix and establish, and revise from time to time whenever necessary, the rentals, rates and other charges for the use and operation of the Airport and for services rendered by the City in the operation of it in order that Revenues in each Fiscal Year, together with Other Available Moneys deposited with the Trustee with respect to that Fiscal Year and any cash balance held in the Revenue Fund on the first day of that Fiscal Year not then required to be deposited in an Fund or Account, will be at least sufficient... to provide for... One and ten-hundredths times (l.lOx) Aggregate Senior Lien Debt Service for the Bond Year commencing during that Fiscal Year, reduced by any proceeds of Airport Obligations held by the Trustee for disbursement during that Bond Year to pay principal and interest on Senior Lien Bonds or Senior Lien Obligations.

CJTY OF CHICAGO

In addition to Airport Revenues, the City also pledged as Other Available Moneys PFC Revenues through 2018 equal to the amount of annual debt service on the Series 2008A and Series 2010F Bonds, and through maturity on the Series 2011A Bonds, plus any required coverage on all of those bonds. The City is evaluating the use of PFC Revenue after calendar year 2018 and-in its sole discretion plans to continue.to use PFC Revenues to pay debt service on the Series 2008A Bonds and the Series 2010F Bonds. Therefore, the financial analysis in this Report assumes that PFC Revenues will be applied to pay debt service on the Series 2008A and Series 2010F Bonds, or any bonds refunding those bonds (including the 2016 Refunding Bonds), from 2019 through the end of the Projection Period. PFC Revenues will be pledged as Other Available Moneys to the Series 2011A Bonds, or any bonds refunding those bonds, and the 2016F New Money Bonds through the maturity of those bonds.
The City has pledged as Other Available Moneys certain Grant Receipts from FAA Letter of Intent grants and other FAA discretionary grants to the debt service on the Series 2011B Bonds, in addition to Airport Revenues. It is assumed in this analysis that certain Grant Receipts from FAA Letter of Intent grants will be pledged to pay debt service on the 2016E New Money Bonds through the Projection Period. As shown, the Debt Service coverage ratio is projected to meet the minimum requirement of l.lOx in each year of the Projection Period.
Table S-4 presents the projected CPE from 2016 through 2025. The CPE includes estimated debt service and expenses of OMP Airfield Projects and the 2016-2020 CIP during the Projection Period. The aforementioned assumptions on projected costs, along with the forecast passenger activity, provide the basis for R&A's opinion that costs at the Airport remain reasonable through the Projection Period.

Additional information on the financial analysis is provided in Chapter 5 of this Report.

1.2 Indenture of Trust


Security for the Series 2016 Bonds
Pursuant to the terms of the Senior Lien Indenture, the 2016 Bonds will be secured by a first lien pledge of Revenues (meaning, generally, all amounts received or receivable, directly or indirectly, by the City for the use and operation of O'Hare (excluding the Land Support Area)), on a parity basis with the City's Outstanding Senior Lien Bonds and such other Senior Lien Obligations as may be outstanding from time to time, and will be paid from amounts that may be withdrawn from the Debt Service Fund created under the Senior Lien Indenture. Revenues are defined in the Official Statement.

Under the Senior Lien Indenture, the City has covenanted to establish rentals, rates, and charges for the use and operation of the Airport so that Revenues, together with certain other moneys deposited with the Trustee, are sufficient to pay the Operation and Maintenance (O&M) Expenses at the Airport and to satisfy the debt service coverage covenants contained in the Senior Lien Indenture.

The City is a party to the Airport Use Agreements with certain airlines serving the Airport, which Airport Use Agreements are scheduled to expire on May 11, 2018. Following the expiration of the Airport Use Agreements on May 11, 2018, the Senior Lien Indenture provides that, beginning on the first Business Day of June 2018, or another date as the City may select and designate in a Certificate filed with the Trustee (the Transition Date), certain new Funds and Accounts will be established and the application of moneys in the Revenue Fund will be revised. See Section 5.1.1. of this Report for additional information regarding the Airport Use Agreement and assumptions made in the financial analysis.

, and. (B) one and ten hundredths times the Aggregate "Debt Service for the Bond Year commencing during that Fiscal Year, "reduced by any proceeds of Airport' Obligations held by the Trustee for disbursement during that Bond Year to pay principal of and interest on Senior Lien Obligations.
The City further covenants in the Senior Lien Indenture to fix and establish, and revise from time to time whenever necessary, the rentals, rates, and other charges for the use and operation of the Airport and for services rendered by the City in the operation of it in order that Revenues in each Fiscal Year, together with Other Available Moneys consisting solely of: (a) any PFC revenues deposited "with: theiTrustee for that Fiscaj Year; and (b) any other moneys received by the City in the immediately prior Fiscal Year and deposited with the Trustee no later than the last day of the immediately prior Fiscal Year, will be at least sufficient:

to provide for the payment of Aggregate'Debt Service for the Bond Year commencing during that Fiscal Year, reduced by'any proceeds of Airport Obligations "held by the Trustee for disbursement during the Bond Year to pay the principal of and interest on Senior Lien Obligations.

Flow of Funds
Airport Revenues and expenses are accounted for as a separate enterprise fund of the City, subject to the provisions of the Senior Lien Indenture and, prior to the Transition Date, the Airport Use Agreements. The Flow of Funds identified in the Senior Lien Indenture, both before and after the Transition Date, is illustrated graphically on Exhibit 1-1. Additional information regarding the Flow of Funds, including the flow of PFC Revenues, is described under "Flow of Funds" in the Official Statements for the 2016 Bonds and in the Senior Lien Indenture.

Additional Bonds

The City may issue Refunding Bonds, such as the Series 2016A Refunding Bonds, the Series 2016B Refunding Bonds, and the Series 2016C Refunding Bonds, and Completion Bonds either by satisfying the debt service coverage requirement, or by satisfying the applicable requirements in the Senior Lien Indenture.

" ~2~The Airport Facilities,
Capital Program, and 2016 Projects


The Airport is the primary commercial-service airport serving Chicago and the surrounding region. This
chapter presents a summary of existing Airport facilities and describes the ongoing capital program at the
Airport-rinc-luding the 2016-Projects.- - -~~ --V

2.1 Airport Facilities

The Airport occupies over7,200 acres of land 18 miles'northwest of downtown Chicago. Its primary facilities consist of the airfield, terminal area, rental car facilities, air cargo areas, maintenance/airport support' areas, and surface access/parking areas. These facilities are described in the following sections.
AIRFIELD ' 3'
Currently, the airfield contains eight active runways. The existing Airport layout is shown on Exhibit 2-1. The O'Hare Modernization Program (OMP) includes a reconfiguration of the airfield from intersecting runways to a predominantly east-west parallel runway layout. To date; three of the four runways included in the OMP have been completed and one of the two planned runway extensions has been completed. A discussion of the OMP is provided' in Section 2.2.1. A network of taxiways, aprons, and aircraft holding areas supports the runways. All runways have electronic and other navigational aids that permit aircraft to land in most weather conditions. The Airport's first runway to meet Airplane Design Group (ADG) VI standards, for the Airbus A380 and the Boeing 747-8, opened in 2013.
TERMINAL AREA
The airlines serving the Airport operate from four terminal buildings with a total of 189 gates.1 Three terminal buildings, with a total of 170 gates, serve domestic flights and certain international departures. The domestic terminal complex is centrally located within the airfield area. The domestic terminal complex includes Terminal 1 (Concourses B and C), Terminal 2 (Concourses E and F), and Terminal 3 (Concourses G, H, J, K, and L). Gates in the domestic terminal complex are leased by the airlines on an exclusive-use basis, with the exception of eight gates in Terminal 3 that are leased on a preferential-use basis and one gate in Terminal 2 and nine gates in Terminal 3 that are accessed on a common-use basis.

A gate is an active aircraft parking position that is accessed through the terminal building, either via a passenger loading bridge or other means, customarily used for enplaning and deplaning passengers. The number of gates is subject to change based on the configuration of aircraft parking

CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT NOVEMBER 3, 2016


Terminal 5 (Concourse M), also known as the International Terminal, is located in the eastern portion of the terminal area and has 19 gates.and 4 hardstand2 aircraft parking positions. The International Terminal serves most international departures and all international arrivals requiring Federal Inspection Services (FIS). In July 2016, the reconfiguration of a gate in the International Terminal to accommodate Airbus A380 aircraft was completed. Gates in the International Terminal are all common-use. The Airport Transit System (ATS) .provides transportation among the four terminals and the long-term pa

Also located within the terminal area are a hotel, a parking garage, and the Airport heating and refrigeration plant. The 10-story hotel, leased and operated by Hilton Hotels Corporation and located directly across from Terminals 1, 2, and 3, provides approximately 860 guest rooms, as well as restaurants and meeting facilities. The 6-story parking garage adjacent to the domestic terminals contains approximately 9,300 spaces for public and employee parking. The heating and refrigeration plant, located northeast of the domestic terminals, provides heating and air conditioning for all terminal buildings. A discussion of recently announced capital projects that will impact the terminal facilities, including terminal expansion and hotel redevelopment, is provided in Section 2.2.3 of this Chapter.
RENTAL CAR FACILITIES
On-Airport rental car facilities are currently located on Airport property remote from the terminals; company-specific shuttle buses operate between the rental car facilities and .the terminals. Eight rental car .brands currently operate on-Airport: Alamo, Avis, Budget, Dollar, Enterprise, Hertz, National, and Thrifty. Off-Airport rental car operators include Advantage Rent A.Car, EZ Rent-A-Car, Payless Car Rental, and Silvercar. As part of the Airport's capital program, the City is constructing a Multimodal Facility, which will include a consolidated rental car facility (CRCF) with an associated quick turnaround (QTA) area and access to the Airport terminals via an extension to the Airport's ATS. Section 2.2.2 provides additional information on the Multimodal Facility.
AIR CARGO AREAS
The Airport is a major center for air cargo shipments; it ranked second in the United States in 2014 in terms of the value of shipments.3 In the area surrounding the airfield, 16 buildings are used for air cargo operations. A new 820,000-square-foot cargo center is being developed by Aeroterm, a third-party developer, in the northeast cargo area. The first two phases of the Northeast Cargo Facility are under construction and scheduled to be open in 2016.
MAINTENANCE/AIRPORT SUPPORT AREAS
Nine aircraft maintenance facilities leased by airlines are in the northwest corner of the Airport (the North Maintenance Hangar Area), along with four additional buildings used for airline ground equipment maintenance, two flight kitchens, and a large aircraft service center. In addition to the North Maintenance Hangar Area, other Airport support areas surround the airfield. The Airport Maintenance Complex, which is used to store snow removal and other Airport maintenance equipment, an additional flight kitchen, and miscellaneous ground support equipment facilities are located within the Airport support area on the

A hardstand is a paved area for parking airplanes that is remote from the terminal building. Hardstands can be used for repairs and overnight parking, as well as for enplaning and deplaning passengers.

used for general aviation activity, air cargo operations, aircraft fuel distribution, and the Chicago Department
of Aviation (CDA) office. ' <-¦'•¦'

2.1.6 SURFACE ACCESS/PARKING AREAS
Access to the passenger terminal complex is provided via Interstate 190 (1-190) from the east side of the Airport. This roadway may be accessed from 1-90 or Mannheim Road, which borders the Airport to the east. Other roadways that surround' Air'p'drt property include'I:294'to the east, West Higgins'Road and Touhy Avenue to the north, York Road to the west, and Irving Park Road to the south.

2.2 Overview of Capital Program

The City has been undertaking major capital planning initiatives at the Airport, including airfield and facility development, while also maintaining a 5-year Capital Improvement Program (CIP) to address the Airport's ongoing capital needs. The Airport's capital program includes the OMP Airfield Projects, the 5-year (2016-2020) CIP, and other recently announced capital projects, which are briefly described in this section and further described in Sections 2.2.1 through 2.2.3.
OMP Airfield Projects are changing the airfield from a layout with sets of intersecting runways to a modern parallel runway system. The OMP, which includes construction of'one new runway, relocation of three existing runways, and the extension of two existing runways, is being undertaken in phases that began in 2005. To date, three of the four runways have been completed and one of the two

The feasibility of a future express rail third-party project connecting the. Airport to the central business district is currently being studied. Additional information on the recently, announced capital projects is provided in Section 2.2.3.
Exhibit 2-2 depicts the future airport layout following completion of the remaining OMP Airfield Projects. Also included in this exhibit are additional capital projects at the Airport that are currently under construction, design, or consideration.
Table 2-1 presents the estimated costs and sources of funds for the remaining OMP Airfield Projects and 2016-2020 CIP. Additional information on the sources and uses of funding for these projects can be found in Sections 2.2.1.1 and 2.2.2.1. The other recently announced capital projects are still in preliminary conceptual planning and discussion phases; due to the uncertainty of timing and project costs these projects are not included in Table 2-1.

2.2.1 O'HARE MODERNIZATION PROGRAM
Under the OMP, the airfield is being reconfigured into a modern parallel runway system, allowing for more efficient operations. Prior to OMP, the airfield included sets of intersecting runways built upon the original runway configuration of the 1940s. The OMP is a reconfiguration of the airfield into an east-west parallel runway layout, which results in reduced delays and enhanced capacity. The nearly completed OMP is a comprehensive program providing for the phased reconfiguration of the airfield from sets of converging parallel runways in three main directional orientations (northeast/southwest, east/west, and northwest/southeast) to six parallel runways in the east/west direction and two crosswind runways in the northeast/southwest direction."

The O'Hare Modernization Act, passed by the State of Illinois in 2003, restricted the number of active runways at O'Hare to eight The OMP includes a plan to decommission three existing intersecting runways, two of which have already been closed, as the east-west parallel runways are constructed, resulting in no more than eight active runways in any phase. A state law signed in 20.15 allows up to 10 active runways at the Airport.

Report of the Airport Consultant

CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT


The first phase of the OMP Airfield projects (OMP Phase. 1) was completed in 2013 with the commissioning of Runway 10C-28C. This phase also included the construction of Runway 9L-27R, the extension of Runway 10L-28R, and a new airport traffic control tower, which were all commissioned in 2008. The second phase, OMP Phase 2A, includes the construction of.Runway 10R-28L,,north airfield enabling projects, and the first phase of the construction of Taxiway LL Runway 10R-28L was completed and commissioned in October 2015. The remaining OMP Phase 2A projects are anticipated to be completed by early 2017.

The Airport, in accordance with criteria established by the O'Hare Noise Compatibility Commission, is providing sound insulation of eligible schools andhomes as a part of each phase ofthe OMP.5

In February 2016, the Airline Parties approved Majbrity-In-Interest (Mil) funding authority for an infrastructure plan and airfield development program that continues the runway modernization. This program includes the construction of Runway 9C-27C, an OMP Airfield Project, alorig-.with''additi6nal -airfield improvements which include a deicing pad to allow aircraft to be.deiced away from the gate, and a cross-field taxiway system and relocation of Taxiways A and B,. alhexpected to be funded with the 2016 New Money Bonds. The'additional airfield improvements are not part of the remaining OMP Airfield Projects. Runway 9C-27C will increase the arrival and departure capacity ofthe airfield and:is anticipated to be completed in 2020. The remaining OMP Airfield Projects include an extension to an existing, runway, which is planned to be completed in 202i, but a funding agreement with the airlines has not yet been completed.
Sources and Uses of Fundsior the Remaining OMP Airfield Projects . ....
OMP Phase 1 was completed and fully funded. The total cost for OMP Phase. 1 was approximately $3.2.billion. A-.$l.l. billion funding agreement was agreed upon by the City--and the airline parties for-the construction of the second phase, OMP 'Phase' 2A. This bhase is fully funded and anticipated to' remain Within 'the budget. A $1.3 billion infrastructure plan that includes another OMP runway was agreed upon in a funding agreement among United, American, and the City in January 2016 and Mil funding authority for the plan was approved by the Airline Parties in February 2016. The plan, which includes Runway 9C-27C and additional airfield improvements, will be funded, in part, with proceeds from the 2016 New Money Bonds. Additional sources of funding include PFC Revenues (pay-as-you-go) and FAA Airport Improvement Program (AIP) grant receipts. For purposes ofthe financial analysis included in Chapter 5 of this report, additional future GARBs, described in Section 5.5 of this Report, have been included for funding approximately $361.4 million of the remaining OMP runway extension project.

As shown in Table 2-1, the remaining OMP Airfield Projects are funded by a combination of FAA grants, previously issued bonds, the 2016 New Money Bonds, future GARBs, and PFC Revenues (pay-as-you-go).
OMP Airfield Project Benefits
The OMP was developed to address severe aircraft delays at the Airport. The OMP Airfield Projects are reducing delays and enhance airfield capacity. The projects provide the ability to operate triple independent, simultaneous approaches in poor weather conditions and quadruple independent, simultaneous approaches


Sound insulation may include the following installation of heating and air conditioning systems, replacement of existing windows and exterior doors with sound-insulating windows and doors, addition of dry wall to interior walls, and addition of baffling devices to exterior vents

in clear weather conditions. Additionally, the OMP includes construction of two ADG Vl-capable runways, Runways 10C-28C (completed in 2013) and 9C-27C (anticipated completion in 2020), which meet standards for aircraft with wingspans exceeding 214 feet. ADG VI aircraft include the Airbus A380 and Boeing 747-8.
Since the implementation of the OMP Airfield Projects, the arrival and departure throughput rates at the Airport have increased. With the opening of Runway 9R-27L and the Runway 10L-28R extension in 2008, Runway 10C-28C in 2013, and Runway 10R-28L in 2015, the average ho.urly arrival throughput rates have increased approximately 20 percent. The runway projects eliminated "converging runway operations," which were addressed by the FAA. in 2014 nationwide with the implementation of new rules to manage runways with converging flight paths,.which further decreased the efficiency of O'Hare's intersecting .runways. Without the OMP Airfield Projects, the 'Airport's capacity could have been further reduced as a result of the "converging runway operations" rule.
Annual aircraft operations at O'Hare reached a high in 2004 of nearly 1 million total annual operations. Since the peak in 2004, annual-Operations have-;remained-relatively-'steady, averaging^approximately 880,000 total operations per year since -2010. While annual operations have remained steady,, peak hourly demand at O'Hare was at a 10-year high.in 2014 and at a similar level in 2015. This peak hourly demand is partially due to the rebanking of flight schedules by both major airlines at O'Hare—allowing them to concentrate and reduce connection times during peak travel periods. The increase in throughput gained from implementation of the OMP has provided the airfield capacity necessary to handle this flight schedule rebanking.
Exhibit 2-3 shows the general decrease in system delayed flights at the Airport and historical operations following the implementation of OMP Airfield Projects. Also shown are periods of restricted operations at.the Airport due to the High Density Rule6 and FAA flight caps7.



















The High Density Rule is a federal regulation established in 1969 to manage congestion at five high density airports, including O'Hare The rule established limits on the number of all take-offs and landings during certain hours. The rule was relaxed by the U S Congress in 2000 and was phased out completely at O'Hare by July 2002.
In November 2004, the FAA and the airlines serving the Airport agreed to voluntarily limit scheduled domestic and Canadian arrivals at the Airport In October 2006, the FAA implemented a formal flight reduction rule at the Airport (with the same limitations that were voluntary), which expired in October 2008.

The remainder of the 2016-2020 CIP is being funded by FAA'AlP Discretionary arid Entitlement Grants, TSA Funds, previously issued GARBs, and future'GARBs. ¦

2.2i3 OTHER RECENTLY ANNOUNCED CAPITAL PROJECTS
The City is undertaking capital projects intended to provide Airport facilities witfi the ability to accommodate long-term demand into the 21st Century. Recently announcedcapital projects that support this demand are described in the following sections.
Concourse L Extension -
In February 2016, the City announced an-exparisibn'projecrbf existing-1 Concourse; L in Terminal'3; Five hew gates will be added to Concourse L to accommo'date existing ahdfuture demand. The new Concourse! gates comprise the first expansion of gate capacity since the International Terminal was built in 1993; this is also the first domestic gate expansion since Terminal 1 was built in 1987. The Concourse L Extension'is expected to be completed in 2018 and is being funded directly by American Airlines. No other airline approval is required for this project.
Hotel Development
In June 2016, the City announced three hotel development projects to add capacity at the Airport. The projects include the construction of two new hotels and the modernization ofthe existing'terminalhotel. CDA intends to develop a new hotel adjacent to the International Terminal, accessible to the ATS, with 300^00 rooms, 25,000-65,000 square feet of conference space, banquet rooms, and other amenities. A second 150-200 room hotel is expected to be developed by a third party as part of a new mixed-use commercial development adjacent to the Multimodal Facility and adjacent to a 200,000 square foot office complex. Both will also be accessible to the terminals via the ATS. Plans also exist for a renovation and modernization of the existing terminal hotel when the current lease expires in 2018. The total investment for the three development projects is estimated to be approximately $350 million, planned to be funded by a special facility loan backed by hotel revenues, and construction is expected to be complete between 2020 and 2022.

The total estimated tost of the Multimodal Facility included in the 2016-2020 CIP is $732 million, which is fully funded through a combination of previously issued GARBs and the Airport Development Fund ($158 million), PFC Revenue (pay-as-you-go) ($3 million), CFC pay-as-you-go revenue ($166 million), previously issued CFC revenue-backed bonds ($183 million), and a U.S DOT TIFIA direct loan ($272 million) secured by CFC revenues on a subordinate basis to the CFC bonds. The total estimated project cost is currently $785 4 million, which reflects an additional $3 4 million of project costs agreed to pursuant to a letter agreement between the City and the rental car companies.

Report of the Airport Consultant

CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT


Requests for Proposals for an Operator Agreement for the terminal hotels and for a Development Agreement for the mixed-use commercial development are expected to be issued' in .the fall of 2016. Because a detailed funding plan does, not yet exist for the hotel development, the financial analysis in this Report does not include future funding of this project.
Terminal 5 Expansion
The City is undertaking an expansion and set of modifications to Terminal 5 to accommodate increased traffic at the Airport. The current gate configuration in the terminal does not provide optimal scheduling of aircraft, as smaller gate sizes are not compatible with capacity demand. The Terminal 5 Expansion increases both the number (from 19 to 28) and the size of gates in Terminal 5. The project includes an extension of the east concourse of Terminal 5, which includes the addition of approximately 279,000 square feet of gross floor area; the addition of 9 aircraft parking positions and installation of associated passenger loading bridges; and the extension of sterile corridors feeding the FIS facility. The project also includes the expansion of the existing terminal apron by approximately 1.5 million square feet, increasing total linear feet of gate frontage by approximately 25 percent.
The Terminal 5 Expansion also includes the reconfiguration of gates on the west concourse of Terminal 5. Gates Ml through M6 will be modified to accommodate eight narrowbody aircraft. Existing passenger loading bridges will be modified, and new passenger loading bridges will be added to provide access to the terminal for the reconfigured gates. Existing Terminal 5 facilities will also be modified to accommodate additional activity anticipated from the terminal expansion and the modification of existing . gates. Modifications to systems include the expansion of the security screening checkpoint; the modification of the baggage system, ticket counter lobby facilities, and FIS inspection areas; and other projects: Also included in the project is the'Airport's second Airbus A380-capable gate, with holdroom space specifically designed for the aircraft.
It is anticipated that the Terminal 5 Expansion will be completed in 2019 at a cost of $266.8 million. The project will be funded with PFC Revenue (pay-as-you-go and PFC Revenue Bonds anticipated to be issued in 2017 to fund approximately $188.6 million of project costs) and Airport discretionary funds, and no airline approval is required. Additional information regarding future PFC Revenue Bonds is provided in Section 5.4.1 of this Report.
Terminal Area Plan
In addition to near-term gate expansion projects, long-term terminal development and redevelopment options are being evaluated as part of a recently announced Terminal Area Plan (TAP). The City's goals include strengthening the Airport's connectivity, capacity, and efficiency; improving passenger experience; and modernizing existing terminals and their functional and commercial spaces. The City and airline representatives are collectively evaluating terminal development options. Current plans under consideration for the TAP include the redevelopment of Terminal 2 into a new central terminal within the existing terminal complex. Amenities in the new terminal could include a new U.S. Customs and Border Protection facility, a departure hall with additional space for TSA passenger screening, concessions, and passenger amenities. The TAP also examines new concourses to be constructed to the west. The TAP is still in preliminary conceptual planning and discussion phases, and while funding for the TAP is anticipated to include future bond proceeds with debt service payable during the Projection Period, due to the uncertainty of timing and project costs, the financial analysis included in Chapter 5 does not include any debt service payments associated with the TAP.

3. Demographic and Economic Analysis


The demand for air transportation is, to a large degree, dependent upon the demographic and economic characteristics of the geographical area served by an airport, commonly referred to as an airport's air trade area. This dependence is particularly significant for O&D passenger traffic, which has historically accounted for approximately half of the passenger traffic at the Airport. The major portion of demand for air transportation at the Airport, therefore, is influenced more-by the local characteristics of the area served by the Airport than by individual airline decisions regarding service patterns in support of connecting activity. This chapter1 presents data indicating that the Airport's 15-county Air Trade Area has an economic base capable of supporting increased airline traffic demand through the Projection Period (ending FY 2025).

3.1 The Air Trade Area

The borders of an airport's air trade area are influenced by such factors as the location of other metropolitan areas and their associated airport facilities. For purposes of this Report, the Air Trade Area for the Airport consists of the Chicago-Naperville-Elgin Metropolitan Statistical Area (MSA)2 and the Kankakee MSA. As presented on Exhibit 3-1, the Air Trade Area encompasses 15 counties in three states: Cook County, DeKalb County, DuPage County, Grundy County, Kane County, Kankakee County, Kendall County, Lake County, McHenry'County, and Will County in Illinois; Jasper County, Lake County, Newton County, and Porter County in Indiana; and Kenosha County in Wisconsin.











This chapter was prepared, in part, by Partners for Economic Solutions, a consulting firm based in Washington, D C that specializes in regional economic analysis.
A Metropolitan Statistical Area is a geographic entity delineated by the Office of Management and Budget (OMB) for use by Federal statistical agencies in collecting, tabulating, and publishing Federal statistics. Metropolitan Statistical Areas have at least one urbanized area with a population of 50,000 or more, plus adjacent territory that has a high degree of social and economic integration with the urbanized area, as measured by commuting ties

3.2 Demographic Analysis

POPULATION
With a population of mo.re.than 9.7 million, in 2015, .the. 1.5-county Air Trade Area is the third .most populous metropoljtan.region in the United States (see. Exhibit. 3-2). and is a major.air transportation market.

Population growth is a key factor creating demand for airline travel. Data in Table 3-1 show that the Air Trade Area added approximately 329,000 to its population between 2005 and 2015, or approximately 32,900 per year. The Air Trade Area's historical rate of population growth was higher than that of the Midwest population, but it was lower than that of the United States—a relationship that is expected to prevail through 2025. The Air Trade Area population forecast for the period 2015 through 2025 reflects a compound annual growth rate (CAGR) of 0.6 percent—a rate that is higher than what is projected for the Midwest (0.4 percent) but lower than what is projected for the United States (0.9 percent). The projected increase of approximately 560,000 new residents in the Air Trade Area during this period is expected to generate additional demand for airline service at the Airport.

3.2.2 AGE DISTRIBUTION AND EDUCATION
Demand for airline travel varies by age group, and this is a factor influencing O&D passenger activity at the Airport. According to Consumer Expenditure Survey data from the U.S. Department of Labor, Bureau of Labor Statistics, in the United States, persons between the ages of 35 and 54 account for 42 percent of expenditures on airfares.3

Table 3-2 shows that in 2015, residents in the 15-county Air Trade Area aged 35 to 54 accounted for 27.1 percent of the population. Thus, the age group that generates the most expenditures on airfares is represented in the Air Trade Area at a higher rate than the population in both the Midwest (25.9 percent) and the United States (26.0 percent).

According to Consumer Expenditure Survey data, persons with a college degree generate a high percentage of expenditures on airline travel. Data indicate that 77 percent of airfares are purchased by college graduates, while 17 percent are purchased by consumers who have had some college, and 6 percent are purchased by consumers who never attended college.'1 As shown in Table 3-2, 42.6 percent of the Air Trade Area's population over the age of 25 have a post-secondary degree (associate's, bachelor's, master's, or doctorate)— a higher percentage than the populations of both the Midwest (36.9 percent) and the United States (38.2 percent).

In addition to having a. highly educated population, the Air Trade Area is .also home to 42 colleges and universities with total enrollment of approximately 292,000 students. These educational institutions generate demand for airjine service through .academic meetings and. conferences, visiting professorships, study abroad programs, and individual student and faculty travel.

3.2.3 PER CAPITA PERSONAL INCOME
Another key indicator of a region's demand for airline travel is per capita personal income.5 Per,.capita personal income indicates the relative affluence of a region's residents, as well as their ability to afford airline travel. It can also be an indicator of an area's attractiveness to business and leisure travelers. Regions with higher per capita personal income often have stronger business connections to the rest of the nation, as well as a more developed market for tourism.

Exhibit 3-3 presents historical per capita personal income for 2005 through 2015 for the 15-county Air Trade Area, the Midwest, and the United States. As shown, between 2005 and 2015, per capita personal income in the Air Trade Area was higher than that of the Midwest and the United States. Per capita personal income for the Air'Trade Area increased at a CAGR of 0.7 percent between 2005 and 2015, which is lowerthah' the rate in both the Midwest (0.9 percent) and the United States (1.0 percent) during the same period.'

Exhibit 3-3 also shows that projected per capita personal income in the Air Trade Area' is expected to increase at a CAGR of 1.5 percent, from $51,766 in 2015 to $60,303 in 2025.6 The projected growth rate for per capita personal income in the Air Trade Area (1.5 percent) is slightly lower than that of the Midwest (1:6-percent) and equal to that of the United States between 2015 and 2025.





















Per capita personal income is the sum of wages and salaries, other labor income, proprietors' income, rental income, dividend income, personal interest income, and transfer payments, less personal contributions for government social insurance, divided by the region's population

3.2.4.1 ' 'Households wit^ ;; ' " :/ ¦ ;i !
The percentage of higher-income households (defined as those earning $100,000 or more annually) within the Air Trade Area is another key indicator of potential demand for airline travel. According to Consumer Expenditure Survey data from the U.S. Department of Labor, Bureau of Labor Statistics, 54 percent of airfare expenditures are made by households with annual incomes of $100,000 or more.7 With approximately 1,021,000 households earning $100,000 or more in 2015, the Air Trade Area is among the wealthiest markets in the United States.

3.3 Economic Analysis

3.3.1 PER CAPITA GROSS DOMESTIC/REGIONAL PRODUCT
Per capita gross domestic product (GDP; U.S.-level data) and per capita gross regional product (GRP; state-and county-level data) are measures of the market value of all final goods and services produced within a defined geographic area, divided by the total population of the area. These indicators are broad measures of the economic health of a particular area and, consequently, of the area's potential demand for airline travel.

The 15-county Air Trade Area is the largest inland region in the United States with a global reach; if it were measured as a country, it would be the 30th largest economy in the world.11 Since adopting a regional Plan for Economic Growth and Jobs in 2014, World Business Chicago (WBC) has worked with numerous companies and economic development partners to attract, retain, and create new businesses in the Air Trade Area. The Plan for Economic Growth and Jobs is an effort by the government and businesses to promote regional economic prosperity. Its 10 strategies for growth include: expand advanced manufacturing; attract national and international headquarters; improve transportation and logistics; promote Chicago as a premier tourism destination; expand regional exports; improve workforce training; foster innovation and entrepreneurship;

Monthly unemployment data published for the Air Trade Area are not seasonally adjusted.
In August 2016, the seasonally adjusted unemployment rate was 4.8 percent in the Midwest and 4.9 percent in the United States World Bank, International Comparison Program database, site (accessed August 2016).

invest in next-generation infrastructure; leverage neighborhood assets to support regional growth; reduce bureaucracy and streamline government services.12
As a result of the Plan for Economic Growth and Jobs and efforts by WBC, in 2015 Chicago was named "Top Metro for Corporate Investment" by Site Selection magazine. After targeting key industries, such as biotech, e-commerce, food products, and advanced manufacturing, companies such as Amazon, ConAgra Foods, Echo Global Logistics, Glassdoor, Google, GrubHub, Mead Johnson Nutrition, and Motorola Solutions have added jobs and expanded operations in the Air Trade Area. In 2015, 704 business expansions added more than 47,000 jobs to the Air Trade Area and contributed approximately $6.2 billion to the regional economy.13 According to Choose Chicago, there were approximately 11.7 million business visitors to the Chicago metropolitan area in 2015, an increase of 5.1 percent over the previous year. The Chicago area is also ranked seventh in the world in terms of the number of foreign direct investment projects (excluding projects of less than 10 jobs), the only North American city in the top 2014.

3.3.4 TRADE BY AIR
The Air Trade Area's outstanding access to overseas markets gives businesses in the region .the ability to operate internationally. Many of the Air Trade Area's major employers depend on offshore plants and suppliers for manufacturing-and-assembly, as well as for raw materials. This expanding international business activity generates demand for international airline travel and air freight services. In 2015, total trade activity (total imports and exports) between the Chicago Customs District15 and the rest of the world was valued at $180.0 billion. In 2015, more than $141 billion in trade through the Chicago Customs District was conveyed by air. This represents approximately 79 percent of all trade through the Chicago Customs District and more than 64 percent of the Midwest's value of total trade by air (see Table 3-3). The Air Trade Area's high rate of trade by air reflects the prevalence of the just-in-time inventory management of high-value goods (especially in the electronics and industrial components sectors), as well as an expanding global network of suppliers and manufacturers.

4. Air Traffic


This section describes the airlines serving the Airport, historical airport activity, factors affecting aviation demand, and forecast airport activity.

4.1 National and Global Perspective ofthe Airport

Based on U.S. DOT survey data, the Chicago market1 was ranked fourth in the nation in terms of domestic O&D passengers in calendar year 2015 - following the New York2, Los Angeles3, and San Francisco" markets. With its proximity to the center of the United States, its facilities to accommodate domestic and international passengers, and its status as the largest mid-continent international airport and the largest major "dual hub" airport in the United States (measured by enplaned passengers)5, the Airport is a key component of the national air transportation system.
Table 4-1 presents the Airport's worldwide rankings of activity for calendar year 2015. The Airport served approximately 76.9 million enplaned and deplaned passengers, or approximately 210,800 average daily passengers, during this period. This is an increase from the approximately 70.0 million passengers, or approximately 191,800 average daily passengers, in 2014. The Airport ranked second worldwide in total aircraft operations, with 875,136 takeoffs and landings; fourth worldwide and second in the United States in total passengers; and seventeenth worldwide and sixth in the United States in total cargo. The Airport has historically ranked at or near the top of the world's busiest airports in terms of passenger and operational activity. Through the first eight months of 2016, enplaned passenger volumes have increased 2.5 percent from the same period in 2015.
Chicago's location along the heavily traveled east/west air routes and its large population base make it a natural location for airline hub operations. American Airlines (American) and United Airlines (United), the world's largest and second largest carriers in terms of available seat miles (ASMs) operate major connecting hub operations at the Airport. United and American's use of the Airport as a hub is described in more detail later in Section 4.5. Southwest Airlines (Southwest) also serves the Chicago region at Midway International Airport. Additional discussion of Southwest is contained in Section 4.4.

Includes Chicago O'Hare International and Chicago Midway International Airports
Includes John F. Kennedy International, Newark Liberty International, and LaGuardia Airports.
Includes Los Angeles International, John Wayne Airport-Orange County, Ontario International, Bob Hope, and Long Beach Airports Includes San Francisco International, Metropolitan Oakland International, and Norman Y. Mineta San Jose International Airports. Based on 2015 U S DOT T-100 data.

4.2 Airlines Serving the Airport

The Airport is an important O&D market within'^the networks of the passenger airlines that it accommodates. The Airport also" serves as a major connecting hub for both United and American. Table 4-2 lists the airlines serving the Airport during the 12 months ended August 2016, and includes seasonal service.

Table 4-3 presents the scheduled United States airlines that have served the Airport at any time since at least
2006. The Airport has had the benefit of a large and stable airline base, which has helped promote
competitive pricing and scheduling diversity in the Airport's major domestic markets. As of August 2016,
United and its regional affiliates provided nonstop service from the Airport to 141 domestic markets and 42
international markets6; American and its regional affiliates provided nonstop service to 111 domestic markets
and 19 international markets from the Airport. """"

In addition to United, American and their regional affiliates, other major United States airlines at the Airport include Alaska Airlines (Alaska), Delta Air Lines (Delta), and four low-cost carriers (LCCs): Fr.ontier Airlines (Frontier), JetBlue Airways (JetBlue), Spirit Airlines (Spirit), and Virgin America. Together, these airlines provide nonstop service to a total of 41 domestic markets and two international markets.
The foreign flag airlines that have served the Airport at any time since at least 2006 are listed in Table 4-4. Nineteen of the 37 foreign-flag airlines currently serving the Airport in 2016 have operated at the Airport each year since at least 2006. In addition, the number of new carriers has steadily grown. Twelve new foreign flag carriers have begun service to the Airport since 2013 (Air Berlin, Austrian Airlines, Hainan Airlines, Qatar Airways, Sky Regional and Volaris in 2013; Avianca and Emirates in 2014; Finnair in 2015; and China Eastern Airlines, EVA Air7, and Icelandair in 2016). As shown in Exhibit 4-1, the Airport has the fourth most foreign flag carriers operating in the United States (after John F. Kennedy International, Los Angeles International, and Miami International Airports). Exhibit 4-2 presents the market shares, as measured by 2015 total enplaned passengers at the Airport. In 2015, United and American, and their regional affiliates represented approximately 80 percent of the enplaned passengers at the Airport based on CDA data.

4.3 Historical Airport Activity


The following sections present a review of the Airport's historical passenger activity and air service.

4.3.1 ENPLANED PASSENGER ACTIVITY AND AIRLINE OPERATIONS
Table 4-5 presents historical data on enplaned passengers at the Airport. Total enplaned passengers at the Airport increased by a CAGR of 0.2 percent from 2006 to 2015. In 2015, the airport set a record for passenger enplanements. Enplanements at the Airport grew 9.9 percent from the prior year, with domestic enplanements increasing by 11.2 percent and international enplanements increasing by 2.3 percent: Through July 2016, passenger enplanements have increased 2.7 percent from the record volumes over the' same period in 2015. Further detail regarding recent passenger enplanemerit growthis 'provided" throughout this chapter.

4.3.1.1 Domestic Enplaned Passengers and Operations ".[ z }{
Exhibit 4-3 depicts trends in domestic enplanements 'andSoperatiohs over a 12:year period, included in the exhibit are major.events that impacted:do'mestic:enp.lanements and operations during the period.

Despite the imposition of flight "caps restricting operations beginning in 2004, the Airport reached a record high number of enplanements in 2005. In 2006, the FAA implemented mandatory flight restrictions on operations from the Airport to destinations within the United States and Canada8 due to continued congestion. Though this mandatory restriction limited operations at the Airport, domestic enplanements decreased slightly in 2007, but fell significantly in 2008 and 2009, as a result of the economic recession that began in December 2007 as well as self-imposed capacity reductions by the carriers in response to the economic recession. In 2008, airlines .furtherreduced capacity through consolidation, and aircraft retirements in response to lower demand and record high oil prices. Airlines held capacity relatively flat as the economy began to improve, keeping control on costs and generating higher revenues through increased fares and new fees, while emphasizing service in profitable markets. Domestic enplanements grew in 2010 and then remained relatively constant from 2011 to 2013 as United worked through merger integration issues and American filed for ;bankrup'tcy. protection in 2011. Since 2008, United ,sysfem-wide enplanements have decreased 8.1 percent,while" atthe Airport United enplanements. have decreased.3.1 percent. Over this same timeframe, American system-wide enplanements have grown 3.3'percent while'decreasing 0.9 percent at the Airport. Both United and American have grown at O'Hare in recent years; increasing enplaned passengers 6.4 and 6.8 percent, respectively, since 2013. Exhibit 4-4 presents the system-wide enplaned passenger trends for United and American (including their respective merger partners and affiliates) since 2008.








3 Mandatory flight restrictions became effective October 29, 2006 They expired October 31, 2008 in conjunction with the opening of Runway 9L-27R.

Low-cost carrier'gf'owth at th'e'Air'port has accelerated'since 2013. In' 2014, Spifit"'increase'd seat capacity at the Airport by 17.2 percent from the prior year and in 2015 increased scheduled seat capacity by another 39.6 percent. The airline has increased scheduled seat capacity by another 4.1 percent in 2016, serving 20 destinations by the end of 2016. In the third quarter of 2014, Frontier commenced domestic service at the Airport (prior to 2014 Frontier operated international charter service at O'Hare) and by the end of 2016 it will serve 24 destinations. Frontier has increased scheduled domestic seat capacity by 3.4 percent in 2016. In addition to Frontier and Spirit.low.-cost carriers JetBlue and Virgin America have served the Airport since 2007 and 2011, respectively. Combined, the two carriers offer service to five major destinations: Boston, New York-Kennedy, Los Angeles, San Francisco, and San Juan, Puerto Rico. Additional information on low cost carriers can be found in Section 4.5.2.

In 2015, domestic enplaned passengers increased 11.2 percent over 2014. Scheduled domestic seat capacity increased 5.7 percent during this period. Higher enplanement growth relative to seat capacity growth is due, in part, to United and American's schedule restructuring referred to as rebanking. By rebanking, airlines schedule flights to arrive and depart within a narrow window of time to facilitate efficient connecting itineraries, which maximize the number of connecting passengers that can be accommodated on existing flights and results in fuller aircraft on average. United and American increased domestic seat capacity at the Airport by 1.5 percent and 2.3 percent, respectively, in 2015, driven by increased seats per departure as smaller regional jets seating 50 passengers or less are being replaced by larger regional jets. United's scheduled domestic seat capacity at the Airport has increased another 4.5 percent in 2016, and American's scheduled domestic seat capacity has increased another 2.5 percent. Overall, domestic seat capacity at the Airport is scheduled to increase by 3.1 percent in 2016.

H1N1 Flu Mexicans

SOURCE: City of Chicago, Department of Aviation Management Records, August 2016: Ricondo & Associates, Inc. based on the analysis and assumptions described in the Report, August 2016 PREPARED BY Ricondo & Associates, Inc, August 2016

International enplanements and operations at the Airport remained relatively flat through 2007. Operations began to decline in 2008 as airlines reacted to the worsening economic environment by reducing seat capacity. The recession continued to negatively impact international activity in 2009, and was further impacted by the H1N1 swine flu outbreak that reduced demand to Asia, Mexico, and South America.

Lagging demand for international travel, United's merger integration issues, and the bankruptcy of Mexicana (which at the time was the second largest foreign flag carrier at the Airport) combined to further depress international activity in 2010 and 2011. International enplanements declined to their lowest point of the last 10 years in 2011. International activity began to increase again in 2012 and experienced further growth in 2013 and 2014 as a result of service provided by new foreign flag carriers and the expansion of international service by United and American.
In 2015 new international service was initiated by United to Vieux-Fort, Saint Lucia (UVF), Providenciales, Caicos Islands (PLS), and Ixtapa, Mexico (ZIH). In 2016, new international service was initiated by Icelandair to Reykjavik, Iceland (KEF), and EVA Air is scheduled to begin service to Taipei, Taiwan (TPE) in November 2016. Icelandair and EVA Air are foreign flag carriers that have not previously served the Airport.
In 2015, international enplanements increased 2.3 percent from the prior year. As depicted in Exhibit 4-6, the Airport ranked fourth among United States airports as measured by international enplaned passenger volumes in 2015.

Table 4-6 presents total enplaned passengers by airline at the Airport from' 2011 through 201-5. The' total enplanement share of United and its regional affiliates has declined since 2011 (from 47.3 percent to 44.2 percent). This is the result of a combination of minor capacity reductions by United and growth by other airlines at the Airport, which is consistent with nationwide trends. American and its regional affiliates have also experienced a reduced share of enplaned passengers over the same period (from 37.7 percent to 35.8 percent), despite growth in the total number of enplaned passengers, as a result of growth by other airlines at the Airport. Exhibit 4-7 provides further detail of the-shares of United, American and their regional affiliates at the Airport in 2010 and 2015.

4.3.2 AIR SERVICE
Table 4-7 presents the historical O&D and connecting enplanement shares at the Airport. The share of O&D passengers increased from 47.8 percent in 2006 to a high of 52.4 percent in 2010. In 2015, 08iD passengers comprised 52.3 percent of total Airport enplanements. O&D passenger growth was facilitated by hew domestic seat capacity introduced by United, American, and the low-cost carriers. Further supporting O&D growth was a decline in fares enabled by a decline in oil prices. Through higher passenger volumes, airlines were able to increase passenger revenues despite the lower fare environment.
Exhibit 4-8 shows historical O&D passengers and fares at the Airport and the average annual oil prices. Between 2009 and 2014, O&D passenger volumes grew at a CAGR of 1.7 percent, while average domestic fares grew at a CAGR of 6.0 percent. As the average price of oil hovered above $90, airlines elected to drive revenue growth through higher fares. As a result of declining oil prices in 2015, O&D passengers grew 17.4 percent while fares fell by 11.7 percent. The cost of operating additional capacity has decreased, and airlines have been able to profitably fly passengers at those lower fares. Should the price of oil return to the levels of 2012 and 2013, airlines may reduce capacity and capture revenue growth through higher fares.

An important characteristic of airport activity is the distribution of the Airport's O&D markets, which is a function of air travel demand and available services and facilities" Table 4-8 presents.data on'the Airport's top 50 domestic O&D markets in 2015, the latest full year of data available, as measured by the number of passengers. Given the Airport's central location in the United States, the domestic O&D markets are predominately medium-haul markets (between 601 and 1,800 miles). The Airport's top 50 domestic O&D markets had an average length of haul (i.e., actual passenger trip distance flown) of 1,019 miles, compared to an average length of haul of 1,141 miles nationwide.
Also shown in Table 4-8 are the number of weekly nonstop departures in each of the Airport's top 50 domestic O&D markets for the week of August 8, 2016. The week of August 8, 2016 represents an average week of the busiest month of the year as measured by scheduled departures. Exhibit 4-9 illustrates the domestic markets served nonstop from the Airport as of August 2016. An average of 1,105 domestic departures per day were flown to 161 nonstop destinations in August 2016, which was the most destinations of any airport in the United States during that month and reflects an increase of 29 destinations since August 2009. Exhibit 4-10 illustrates the international markets served nonstop from the Airport as of August 2016. During the month of August, the Airport averaged 128 international departures per day to 56 nonstop destinations.

AIRCRAFT OPERATIONS
Table 4-9 presents aircraft operations levels at the Airport by major user group between 2006 and 2015. A notable trend in passenger airline operations through the period is the increasing number of regional/commuter affiliate operations relative to those of majdfs/nationals. As airline labor agreements have become less restrictive, airlines have increased the amount of capacity, flown using regional aircraft, specifically those seating more than 60 passengers, This has allowe&airlines to increase average seat capacity through the use of larger regional jets. The trend toward regional/commuter affiliate operations at the Airport began to change in 2015, however, as airlines increasingly replaced smaller regional jets with larger regional jets and mainline aircraft. Over the period shown. (2006;2015), relaxation of restrictive labor agreements has enabled a 1.0 percent compound annual decrease in total operations at the Airport, which, as shown on Exhibit 4-11, is similar to operations trends at the 10 largest; North American airports.

4.3.3.1 General Aviation Operations
After an approximately 49 percent decline in 2007 (from 31,912 operations in 2006), general aviation operations have grown from 16,295 in 2007 to 21,828 in 2015. General aviation activity levels at the Airport are influenced by the lower costs and lower delays at outlying airports within the Chicago region. As a result, general aviation activity at the Airport has been relatively low, accounting for approximately 2.5 percent of total operations in 2015.

All-Cargo Carrier Operations
Twenty-two all-cargo operators provide scheduled service at the Airport. FedEx provides the majority of the
all-cargo activity with approximately 6 daily departures. The second busiest all-cargo carrier at the Airport is
United Parcel Service (UPS) with approximately 3 daily departures. Approximately 54.9 percent of all-cargo
operations in 2015 were international flights. Operations by the all-cargo airlines at.the Airport were relatively
stable in 2006 and 2007, averaging approximately 21,000 operations during this period. All-cargo operations
at the Airport decreased 15.2 percent in 2008. from 2007 levels, primarily, due to the temporary
discontinuation of service at the Airport by Korean Air Cargo and. the decrease in service at the Airport by
FedEx and UPS due to increases in fuel prices during this period. High fuel prices' arid a weak economy led to
further reduction in all-cargo operations from 2008 to 2009. Cargo operations at the Airport increased in 2010
and have remained relatively stable since that time as. air .cargo demand, has recovered more slowly than
passenger demand. " 1
Military Operations
In 1996, the City purchased approximately 350 acres of land in the northeast quadrant of the Airport formerly used as a United States Air Reserve station. In 1999, the largest remaining military unit at the Airport, the 126th Air Refueling Wing, was deactivated and relocated:to Scott Air Force Base in St.'.CIair County, Illinois. As a result, no military aircraft operations have been recorded at the Airport between 2006 and 2015.
LANDED WEIGHT ¦ ' , : ;/ :*
Table 4-10 presents the shares of landed weight for the passenger and all-cargo airlines'serving the Airport from 2011 through 2015. Landed weight decreased in 2012 and 2013 but it increased in 2014 and 2015, for a compound annual increase of 1.4 percent over the 5-year period.
AIR CARGO VOLUMES'
In addition to all-cargo service, passenger airlines also served the cargo market, carrying approximately 41 percent of the Airport's cargo volume in 2015. Table 4-11 presents historical' enplaned and deplaned air cargo at the Airport between 2006 and 2015. Similar to the passenger airlines, the air-cargo industry has been impacted in recent years by the global economy, foreign currencies, uncertainties in the Middle East, and new security regulations. Between 2006 and 2015 cargo volumes at the Airport have increased at a CAGR of 0.4 percent. In 2014- and 2015, international cargo volumes increased by 13.1 percent and 13.6 percent, respectively, from the prior year as international cargo markets began to recover from the period of reduced demand for air cargo.

4.4 Factors Affecting Aviation Demand at the Airport

This section discusses qualitative factors that could influence future aviation activity at the Airport. Data and information related to these factors have been either directly or indirectly incorporated into the development of activity forecasts for the Airport.
NATIONAL ECONOMY
Historically, trends in airline travel demand, measured by either passenger volumes or passenger revenue, have been closely correlated with national economic trends, most notably changes in GDP. Chapter 3 presents an analysis of general economic trends, both national and local, that may influence demand for air service over time. As noted in Chapter 3, national GDP is expected to increase at a 2.2 percent annual rate through the Projection Period, which should support increasing demand for air service. Actual economic activity is likely to differ from this forecast, especially on a year-to-year basis, with demand for air service likely reacting in kind.
STATE OF THE AIRLINE INDUSTRY
In the aftermath of the terrorist attacks on September 11, 2001, the United States airline industry experienced a material adverse shift in the demand for airline travel, which exacerbated problems for a United States airline industry already weakened by a slowing economy and rising labor and fuel costs. The result was 4 years of reported industry operating losses in 2001 through 2004, totaling more than $22 billion (excluding extraordinary charges and gains). Following these restructuring years, the airline industry gained ground from


Report of the Airport Consultant

CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT NOVEMBER 3, 2016



2005 through 2007, with United States airlines posting combined operating profits in all 3 years.9 In 2008 and through the first half of 2009, the combination of record-high fuel prices, weakening economic conditions, and a weak dollar resulted in the worst financial environment for United States network and low-cost airlines ¦ since the September 11, 2001 terrorist attacks.

4.4.3 AIRLINE MERGERS AND ACQUISITIONS
Since 2009, airlines have merged or acquired competitors in an attempt to. increase operational synergies and become more competitive and cost efficient. In 2009, Delta completed its merger with Northwest Airlines, initiating a wave of United States airline mergers and acquisitions. That same year, Republic Airways Holdings, a regional airline, acquired Frontier Airlines of Denver and Midwest Airlines of Milwaukee. In October 2010, United and Continental merged, creating the world's largest airline in terms of operating revenue and revenue passenger miles. In 2011, Southwest Airlines acquired AirTran Holdings, Inc., the former parent company of low-cost competitor AirTran. Effective December 9, .2013,. American and US Airways merged, creating the largest airline in terms of operating revenue and revenue passenger miles (surpassing United). Additional consolidation in the United States industry could affect the amount of capacity offered to passengers and alter the competitive landscape.

4.4.3.1 Capacity Discipline —A Change in the Airline Business Model
In 2008, many domestic airlines announced significant capacity reductions, increases in fuel surcharges, airfares and fees, and other measures to address their financial challenges. In 2008 North American International Air Transport Association airlines recorded a $16.8 billion loss. The combination of airline mergers and capacity reductions has dramatically improved the financial conditions for the airlines. In contrast to earlier losses, North American International Air Transport Association airlines are projected to generate profits of $22.9 billion in 2016, after producing $21.5 billion in profits in 2015.10 Strict control on capacity, primarily in the domestic market, referred to as capacity discipline, is the principal driver behind the airline industry's financial turnaround.
Capacity discipline reflects a shift in the airline business model, from an environment where market share targets are pursued to one where financial targets are pursued. The new business model resulted in an approximately 7 percent decrease in United States domestic seat capacity between 2008 and 2014 as airlines shed less profitable capacity and passenger volumes not contributing toward the achievement of financial targets. By allocating the remaining seat capacity to a more profitable segment of passengers, airlines increased domestic load factors from approximately 75 percent in 2008 to approximately 83 percent in 2015. O'Hare experienced similar trends during the same period, as load factors increased from 76.4 percent to 86.2 percent. Exhibit 4-12 illustrates the change in United States airline industry passenger volumes since 2006 relative to the change in U.S. GDP, a driver of demand for air travel.' Both domestic and international passenger volumes followed GDP trends.until 2009, after which domestic passenger volumes remained largely unchanged, while GDP and international passenger volume growth resumed. More profitable international passengers have continued to be accommodated by airlines. Exhibit 4-13 illustrates the change in United States domestic passenger volume, passenger revenues, and United States GDP since 2006. While domestic

CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT



passenger volumes have not followed GDP trends since 2009, another measure of passenger demand, passenger revenue, has increased as United States airlines have focused on achieving financial targets through lower domestic passenger volumes and higher passenger fares. United States domestic seat capacity increased in 2015 and is scheduled to increase further in 2016 as airlines have taken advantage of lower fuel costs to increase capacity to achieve financial targets through growth of passenger volumes.

COST OF AVIATION FUEL
The price of fuel is one of the most significant and volatile expenses for airlines. Historically, fuel has been the first or second largest operating expense for the airline industry, shifting with labor as the cost of fuel fluctuated. According to the International Air Transport Association (LATA), fuel was 31.6 percent and 27.5 percent of operating "costs" for^aiHines'in'2014'and'2015, respectively",' arid'is projected to be 19.7 percent of operating costs for 2016.11
Exhibit 4-14 shows the monthly average prices of jet fuel and crude oil from January 2007 through June 2016. Since 2007 the average monthly price of jet fuel fluctuated between a high of $3.84 per gallon in July 2008 to a low of $1.21 per gallon in February 2016. Since January 2014, the average price of jet fuel has declined 39.8'percent. The decreasing price of oil has provided airlines with more flexibility in terms of pricing and allocation of capacity, while still maintaining a disciplined approach to achieving return on invested capital and profitability goals. Between 2010 and 2014, airlines have managed seat capacity growth at or below United States GDP growth, as several United States airlines have stated as guidance to their capacity growth planning. In 2015 however, domestic seat capacity grew 3.4 percent, exceeding United States GDP growth of 2.6 percent12. In 2016, domestic seat capacity is scheduled to grow 4.2 percent while United States GDP is projected to grow 2.2 percent. Prolonged low' fuel prices have enabied this higher than expected seat capacity growth in a way that may not continue should fuel prices rise.

Fluctuating fuel costs will continue to affect airline profitability and could lead to changes in air service as airlines restructure air service to address increases or decreases in the cost of fuel.
THREAT OF TERRORISM AND GEOPOLITICAL ISSUES
Since, the terrorist attacks of September 11, 2001, the recurrence, of. terrorism incidents against .either domestic or world aviation during the Projection Period remains a risk to achieving the activity forecasts: contained herein. Tighter security measures have restored the public's confidence in the integrity of United States and world aviation security systems. Any terrorist'incident aimed at aviation could have an immediate and significant impact on the demand foraviation services:

OPERATIONAL CAPACITY OF THE NATIONAL AIRSPACE SYSTEM
One of the FAA's concerns is how increased delays, at busy airports impact ,the efficiency. of :the National Airspace System (NAS). In its report Airport Capacity Needs in. the National Airspace System (January 2015), " the-FAA stated the--need^ to implement NextGen airspace system improvements. The report emphasized the need to continue to invest in system improvements with airfield enhancements and NextGen capabilities.
OTHER AIRPORTS IN THE REGION
There are two other commercial service airports in the area; Chicago Midway International Airport and General Mitchell International Airport. In addition, Gary/Chicago International Airport- and the proposed South Suburban Airport are focused ,on future air service ^development. These regional airports and their relationship to the Airport are described in this section.
Chicago Midway International Airport (Midway), classified as a large-hub commercial service airport, is located 15 miles south;of the Airport. The City owns both the Airport and Midway, and the City of Chicago's Department of/Aviation operates the airports. Midway is a hub for Southwest Airlines and serves as the largest airport in its system when measured by both enplaned passengers and operations. In 2015, 43 of Midway's top 50 domestic O&D markets were included in O'Hare's top 50 domestic O&D markets. International service from Midway includes flights to Canada, Mexico, and the Caribbean. Long-haul international markets cannot be served from Midway due to constrained runway lengths.
Table 4-12 presents enplaned passengers for the Airport and Midway between 2006 and 2015. The Airport maintained nearly 81 percent share of total enplaned passengers between 2006 and 2008 despite Southwest's expansion of service at Midway during the period after the bankruptcy of ATA Airlines. Between 2010 and 2013, however, as Southwest grew at Midway, enplanements at the Airport remained relatively stable. As a result, Midway achieved an enplanement share of greater than 23 percent by 2013. However, as the Airport outpaced Midway in enplaned passenger growth in both 2014 and 2015, the Airport's share of total enplaned passengers increased from the low experienced in 2013.

Table 4-13 provides a comparison of average fares and yields for the Airport and Midway. The average fare and yield growth for the Airport and for Midway were similar in 2006 and 2007. In 2008 fares and yields grew more at Midway as a result of the bankruptcy of ATA Airlines. After decreasing in'2009 as a result of the economic recession, fares and yields began to recover at both airports in 2010.'. Fares and yields grew at Midway in 2011 and 2012 as Southwest added additional service on longer range routes.from Midway. After a slight drop in average domestic fares at the Airport in 2012, domestic fares and-yields at both airports grew by a modest rate in 2013 and 2014. In 2015, the Airport and Midway experienced a significant decrease in average domestic fares and yields, as a low fuel cost environment led airlines to expand domestic capacity, maximizing profitability by carrying additional, lower fare-paying passengers. 5 ~

General Mitchell International Airport (General Mitchell) is the nearest medium^-of large-hub commercial service airport outside of Chicago. This medium-hub airport13 is located approximately 70 miles north of the Airport near Milwaukee, Wisconsin. General Mitchell serves the commercial air service needs of Milwaukee, southeast Wisconsin, and portions of northern Illinois. Although General Mitchell is in close proximity to the Airport (overlapping catchment areas include three counties in the northern Chicago region, which represent approximately 12 percent of the population in the region), the higher frequency of nonstop service to key markets from the Airport diverts a portion of potential traffic from the General Mitchell catchment area to O'Hare.
Gary/Chicago International Airport, which is owned by the City of Gary, Indiana and operated by the Gary/Chicago International Airport Authority, is also located in the Air Trade Area (see Exhibit 3-1 in Chapter 3). There is currently no scheduled passenger airline service offered at Gary/Chicago International Airport. In

January 2014 Gary/Chicago International Airport entered into a Public Private Partnership with AFCO/AvPorts to further develop airport property and to increase the economic impact of the airport.

4.5 Importance of the Airport to Airlines


4.5.1 HUB AIRLINES
The Airport represents a strategically important element ofthe route networks of United and American, and is estimated to be the second and fourth highest contributor to their profit, respectively. Measured by seat capacity, it is currently the largest hub in United's network and the fourth largest hub in American's network, and has the second largest number of O&D passengers for both hub airlines.

Exhibit 4-15 presents the estimated operating profit and relative contribution of each of the airlines' hubs. Publicly available sources of financial and operational data were analyzed, and allocation methodologies commonly used in the airline industry were applied to derive estimates of hub financial performance. Ticket revenue was attributed to hubs using DOT O&D data and prorated to flight segments using a distance-based proration methodology. Non-ticket revenue was allocated using drivers that include passenger and cargo volumes. Cost allocation drivers include block hours, departures, passenger volume and Available Seat Miles (ASMs). Aircraft type-specific allocation rates were used where reporting is available in order to represent the economic impact of the mix of fleet types operating across the hubs. While this analysis has applied commonly used approaches to the alignment of costs and revenues with activity based allocation drivers, these estimates of hub profitability may differ from those developed by individual airlines, which employ many different methodologies incorporating detailed internal data sources. Based on this analysis, the Airport is the second highest contributor to profit for United and the fourth highest contributor to profit for American.

As shown on Exhibit 4-16, the Airport contributes the third most revenue among United's hubs and the fifth most revenue among American's hubs. Table 4-14 and Table 4-15 present the percentage of O&D passengers flown by United and American at their hub airports in 2015. The Airport serves 17.5 percent of United's hub O&D passenger base and 14.1 percent of American's hub O&D passenger base, and represents the second largest O&D passenger base for both United and American.
The central geographic location of the Airport allows United and American to efficiently connect passengers within the United States and to many international destinations. As other airports have been dehubbed either through consolidation or as a result of the industry's implementation of the capacity discipline business model, United and American have leveraged their hubs at ORD to accommodate more connecting passengers, especially as underlying market demand grows.

4.5.2 LOW-COST AIRLINES
The Airport is an increasingly important airport within the route networks of several United States low-cost carriers. The low cost structure of these airlines has enabled their growth at the Airport, as they have taken advantage of an increasingly valuable passenger base. In 2011 the City purchased the L Concourse leasehold from Delta Air Lines. By purchasing the leasehold, the City was able to convert five gates on the L Concourse from exclusive use to common use. In 2014 the City acquired an additional two gates on the L Concourse as a result of the merger between US Airways and American, which were also converted to common use. While other gates at the Airport are preferential-use or exclusive-use (meaning a particular airline has priority or the exclusive use of a gate), the seven common use gates on the L Concourse, and the one common use gate in Terminal 2 can be allocated at the Airport's discretion. These gates have been used to allow Frontier, JetBlue, Spirit, and Virgin America to either begin or grow service at the Airport. Since 2009, the Airport's rank as measured by total system-wide departures among these carriers jumped to 9l , from the 25 busiest.
As shown in Table 4-17, between 2009 and 2015, annual low-cost carrier enplanements grew by over 640 percent, from approximately 375,000 to nearly 2.8 million. The greatest year-over-year growth occurred in 2015, when total low-cost carrier enplanements grew 59.5 percent.

4.6 Forecasts of Aviation Demand

Forecasts of aviation demand (i.e., enplaned passengers, aircraft operations, and landed weight) were developed considering historical activity, including passenger volume and revenue trends at the Airport and across the industry, historical trends and future forecasts of local and national socioeconomic factors, and anticipated trends in use of the Airport by American, United, and other airlines. The following section provides an overview of the methodologies used in forecasting activity at the Airport, and it also presents the results of those forecasts through 2025.
4.6.1 ASSUMPTIONS UNDERLYING THE FORECASTS
Forecasts of enplaned passengers, aircraft operations, and landed weight were based on a number of underlying assumptions, including:
The Airport will continue its role serving O&D passengers and as a major connecting hub for United and American Airlines. The Airport will continue to serve as a connecting hub within the United States

domestic route network, and will continue to be an important international-gateway for. European, Asian and Canadian passenger traffic.
There will be no terrorist incidents during the Projection Period that would have significant, negative, and prolonged effects on aviation demand at the Airport or nationwide.
Economic disturbances will occur during, the Projection Period, causing year-to-year variations in airline traffic; however, long-term economic growth is assumed.
No major "acts of God" that may disrupt the national or global airspace system will occur, during the Projection Period-that would negatively.'affect aviation demand. : :- . : J
Major health issues, such as H1N1, SARS, or Zika are not expected to have a prolonged impact on demand during the Projection Period.
Many of the factors influencingV.aviation demand cannot be quantified, and any forecast is subject to uncertainties. As a result, the fprecast should not be viewed as precise. Actual airline traffic at the Airport may differ from the forecasts presented herein because events and circumstances dp not occur as expected, and these.differences may be\m'aterialr:/^"

of actual performance data furnished by the Airport through June 2016, as well as through analysis of USDOT enplanement and O&D data available through April 2016. Estimates of load factors and completion rates were applied to scheduled capacity in order to derive enplanement and operations forecasts for the balance of 2016. For 2017, air service profiles were estimated using a partial year of published airline schedules for the Airport (number of operations, fleet, and seat capacity). 2015 and estimated 2016 load factor trends and completion rates were used as a reference for the development of 2017 passenger activity.

Table 4-19 presents historical and forecast enplaned passengers at the Airport. The'total number of enplaned passengers is forecast to increase 0.4 percent between 2015 and 2016, from approximately 38.4 million to approximately 38.5 million. The number of international enplaned passengers is forecast to increase 2.7 percent in 2016, from approximately 5.5 million to approximately 5.7 million, while the number of domestic enplaned passengers is forecast to remain level. Growth in international enplaned passengers will be supported in part by new service by China Eastern to Shanghai Pudong International Airport, China (PVG) and Icelandair to Keflavik International Airport, Iceland (KEF), as well as increased capacity to existing international destinations such as Heathrow Airport, England (LHR), Warsaw Chopin Airport, Poland (WAW), and Dublin Airport, Ireland (DUB). Domestic enplanement growth will be supported by an overall increase in average seat capacity led by the growth of low-cost carriers Spirit Airlines and Frontier Airlines, who combined, will increase scheduled capacity by 4.7 percent in 2016 from 2015. In addition, average seat capacity per departure at the Airport is expected to increase from 105 in 2015 to 109 in 2016, as low-cost carriers increase the use of large narrowbody aircraft at the Airport, and as United and American increase capacity by upgauging smaller regional aircraft to larger regional jet aircraft and mainline aircraft. In 2017, enplaned passengers are forecast

to grow 1.3 percent, which is supported by a 1:0 percent increase in domestic enplaned passengers and a 2.8 percent increase in international enplaned passengers.

4.6.3 LONGER-TERM (2018 THROUGH 2025) ENPLANED PASSENGERS FORECAST METHODOLOGY
To understand the long-term growth potential of enplaned passengers at the Airport, forecasts of nationwide and local economic activity were examined, as discussed in Chapter 3 of this Report. It was concluded that the economic bases of the Air Trade Area and the nation are diversified, stable, "arid capable of generating longer-term increases in demand for air transportation at the Airport during the Projection Period.

Longer-term passenger demand growth rates at the Airport were derived using socioeconomic regression analysis. Socioeconomic regression analysis is used to identify predictive relationships between a dependent variable (e.g., passenger volume, passenger revenue, or other metric representing passenger demand) and one or more independent variables (e.g., socioeconomic factors, such as population, employment, per capita personal income, etc.). These relationships, or regression models, can be employed to forecast future growth in aviation activity using forecasts of independent variables. A standard measure of how well each • socioeconomic variable explains passenger demand is the regression model's coefficient of determination, or R-squared. A result of 100 percent is the maximum value possible for a coefficient of determination; it represents a perfect fit between the variables analyzed. For purposes of this analysis, an R-squared value of 70 percent or better was considered adequate.

Socioeconomic regression analysis was conducted to identify predictive relationships between passenger demand at the Airport and socioeconomic variables at the national level and for the Air Trade Area16. The Airport serves originating passengers who reside in the Air Trade Area as well as those who visit or connect through the Air Trade Area or Airport for business or leisure. With the Airport's diverse customer Base, demand for air service is driven by factors directly related to demographic and economic characteristics of both the Air Trade Area and the nation. As such, the following five socioeconomic variables were analyzed separately as independent variables in the regression analyses, both for the nation and the Air Trade Area: population, income, per capita personal income, employment, and GRP/GDP. Historical and forecast data for these independent variables were obtained from Woods & Poole Economics, Inc.

4.6.3.1 Passenger Segmentation
The relationship between socioeconomic variables and passenger activity was explored for four segments of demand:

• Origin and Destination (52.3 percent of Airport passengers in 2015):
Domestic O&D: Passengers using the Airport as an origin or destination point for journeys within the United States.
International O&D: Passengers using the Airport as an origin or destination point for journeys to or from points outside of the United States. This category includes passengers whose ultimate destination is an international point, but who use a flight segment to or from another domestic


Because the Airport's O&D activity is affected by surrounding airports, historical relationships for O&D activity were analyzed further to consider historical activity at Midway and General Mitchell However, incorporation of Midway and General Mitchell metrics did not improve regression output, and produced more aggressive growth results. Therefore, for purposes of this analysis, only O'Hare metrics were used in regression modeling.

Airport that serves as the international gateway (for example, a passenger flying from the Airport to Belfast International Airport, Northern Ireland [BFS] via [EWR]). While this type of passenger is on an international itinerary, the Airport reports this type of passenger as a domestic enplanement.
• Connection (47.7 percent of Airport passengers in 2015):
Domestic Connection: Passengers using the Airport as a waypojnt for journeys between two other airports within the United States.
- International Connection: Passengers using the Airport as a waypoint : for journeys between two other airports, at least one of which is an international point. This category includes international to international journeys. This'.category also-includes passengers:who depart from the Airport on a domestic flight after arriving .at the Airport on a flight .from an' international origin/iWhile.ithis type of passenger is-on an international itinerary, the Airport reports this type of passenger.as a ¦domestic enplanement.
Passengers were categorized as described above for analytical.:purposes., While;this .categorization, differs slightly from how the Airport reports passenger activity, passengers were re-categorized to Airport standards for presentation, injable 4-19.

4.6.3.2. . Regression Analysis Specificsi . i-.
The methodology described in this section outlining the approach to determining future airport demand for this forecast was initially provided in the Report of the Airport Consultant for the issuance of the Series 2015 Bonds at the Airport included as Appendix E to the Official Statement for the-Series 2015 Bonds, dated October 8, 2015 (2015 Report). This approach and the rationale described for eliminating other possible methodologies remain unchanged. However, as will be described further below, the timing of the forecast increase in passenger volumes has changed due, in part, to lower fuel costs enabling the carriage of higher passenger volumes in the near term. This section describes certain analyses prepared for the 2015 Report.

Four different regression approaches were utilized to derive the ultimate forecast of enplaned passengers for the Airport. Forecasting models were explored utilizing regression analysis between:

A) Socioeconomic Variables and Passenger Volumes (Single-Variable Regression): Passenger enplanement forecasts commonly employ this approach, leveraging historical relationships between passenger volumes and socioeconomic variables to estimate future passenger volumes. However, as shown in Exhibit 4-13 the capacity discipline business model adopted by United States airlines across their domestic route networks has altered the historical relationship between socioeconomic elements and domestic passenger volumes nationally. This is also the case specifically for the Airport as illustrated on Exhibit 4-20. As a result, predictive relationships between the Airport domestic passenger volumes and socioeconomic elements were not adequate for use in forecasting future domestic air traffic.

Also as illustrated in Exhibit 4-12 and Exhibit 4-13, the historical relationship between international passenger volumes and socioeconomic factors has remained intact, as airlines have continued to accommodate more-profitable international passengers. As a result, adequate regression models were

identified only when analyzing relationships between socioeconomic variables and international enplaned passengers using the Airport. These models generated a range of future CAGRs for international passenger volumes between 2.7percent and 4.0 percent for the period through 2024.

B) Socioeconomic Variables and Passenger Revenues (Single-Variable Regression): Exhibit 4-13 illustrates the continued positive relationship between domestic passenger revenues and socioeconomic variables (in contrast to the relationship between socioeconomic variables and domestic passenger volumes). For the Airport specifically, the same positive relationship between passenger revenues and socioeconomic variables exists for both domestic and international passenger revenues as illustrated on Exhibit 4-21. As illustrated on Exhibit 4-22, since the implementation of the capacity discipline business model by air carriers, revenue growth at the Airport and many other large United States airports has come primarily through increased average passenger fares, and less so through passenger volumes. This is in contrast to several other large airports that have experienced revenue growth through a higher component of passenger volume growth. As a result, the Airport has among the highest passenger yield (cents paid per passenger mile flown) ofthe top 30 United States airports as presented on Exhibit 4-23.

In order to derive passenger volume growth associated with the range of forecasted passenger revenue growth, a second step was necessary to estimate how airlines might capture that revenue at the Airport, through a combination of passenger volume growth and/or passenger fare growth. A range of revenue to passenger "conversions" was developed for application to overall revenue growth forecasts.

C) Both Socioeconomic Variables and Average Fares, and Passenger Volumes (Multi-Variable Regression): Regression analysis was performed, to enable forecasting of passenger volumes given forecasts of socioeconomic variables and a range of possible average fares. Under this regression methodology, several adequate relationships were identified for the domestic and international O&D passenger segments. However, the results of this approach were significantly more aggressive than those generated under the approach described in "B". Therefore, the results of this approach were dismissed.

D) Socioeconomic Variables and Regional Passenger Volumes (Single-Variable Regression):
To take into account the other airports in or around the Air Trade Area, Midway and General Mitchell, regression onglysis was conducted for O&D passenger volumes ot the combined airports and socioeconomic variables in both regions. Forecasts of the Airport's share of O&D passengers among the three airports were applied to those relationships with adequate R-squared values in order to determine the O&D passenger forecast. The approach yielded a more aggressive result than those produced under the approach described in "B". Therefore, the results of this approach were dismissed.
4.6.3.3 Enplaned Passenger Forecast Results
In the forecast included in the 2015 Report, a scenario was selected from the range of passenger volume growth produced by the Socioeconomic Variables and Passenger Revenue approach to forecast enplaned passengers through 2024. This scenario (which produced a 2014-2024 compound annual growth for total enplaned passengers of 1.6 percent) was selected in part for its lower outlook on revenue growth. In addition, the scenario assumed a conservative-to-average passenger conversion. The outlook for revenue growth, as forecast in the 2015 Report remains unchanged in the forecast in this Report. However, the recent reduction in the cost of fuel has resulted in lower-than-expected passenger fares in 2015 and 2016. As previously described, this decrease in fares has helped sustain higher volumes of enplaned passengers in 2015 and 2016. Fares were modeled to gradually return to levels forecast previously, under the assumption that fuel prices will increase in the future. The long-term enplaned passenger volumes are still expected, but incorporate the recent growth, in the near-term. This analysis assumes that fuel prices eventually return to a higher.Jevel. If fuel prices remain low for a longer period of time, fares may also grow at a rate lower than forecast. This could result in a higher volume of enplaned passengers than forecast.

Enplaned passenger forecasts are presented in Table 4-19, re-categorized by domestic and international as indicated in Airport reports. The number of international enplaned passengers is forecast to increase from approximately 5.5 million in 2015 to approximately 6.5 million in 2025, at a CAGR of 1.6 percent for the period. Domestic enplaned passengers are forecast to grow from 32.9 million in 2015 to 34.9 million in 2025, a CAGR of 0.6 percent. In aggregate, total Airport enplaned passengers are forecast to grow from 38.4 million in 2015 to 41.4 million in 2025, at a CAGR of 0.8 percent.

4.6.4 AIRCRAFT OPERATIONS AND LANDED WEIGHT FORECASTS
Forecasts of annual aircraft operations at the Airport are presented in Table 4-20 for 2015 through 2025. Forecasts of passenger airline aircraft operations are based on assumptions of load factor management by the airlines serving the Airport and analysis of future fleet plans. Passenger airline aircraft operations are forecast to increase at a CAGR of 0.1 percent during the Projection Period, with the majority of passenger growth being accommodated through use of larger-capacity aircraft. Specific information regarding forecasts of passenger airline aircraft operations is provided below:

• Average seat capacity for passenger airline aircraft operations at the Airport is expected to increase from 105 seats in 2015 to 117 seats in 2025. This capacity increase is driven primarily by a shift by United and American away from aircraft with 50 or fewer seats to both larger regional jet aircraft and narrow body mainline aircraft. Airlines are able to maintain seat capacity in markets while reducing

CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT NOVEMBER 3, 2016



the number of. flights through, the use of larger regional jet and mainline-aircraft. In 2015, approximately 32 percent of scheduled departures were operated in aircraft with 50: or fewer seats.
• Load factors for 2016 are expected to remain similar to those in 2015. However, as average aircraft seat capacity increases through 2025, the average load factor is expected to decrease slightly from 86.7 percent in 2015 to 84.6 percent in 2025.
General aviation operations at the Airport (including helicopter and miscellaneous operations as reported by the City of Chicago Department of Aviation) are expected to increase marginally, from 21,828 in 2015 to, 22,269 operations in 2025, reflecting the long-term assumption that growth in this sector will occur primarily at outlying airports within the Chicago region as the result of cost and delay considerations. The increase ' between '2015 and '2025- represents a CAGR of 6:2"percent during this period, 'comparable''to 0.4 percent growth'forecast nationwide by the FAA.

All-cargo operations at the Airport increased from 13,988 in 2009 to 17,700 operations in 2014. All-cargo aircraft operations at' the Airport" are forecast to" increase at "fates generally more'conservative than industry cargo volumes in the period and more in line with all cargo aircraft growth in the period as forecast by the FAA. All-cargo aircraft activity at the Airport is forecast to increase from 17,700 operations in 2015 to 21,302 operations in 2025 a CAGR of 1.9 percent."

Future military activity at the Airport will be influenced'by United States Department ot Defense policy, which largely dictates the level of military activity at an airport. As shown in Table 4-20, no military activity is forecast to occur at the Airport during the Projection Period.

In large part as a result of the increased size of passenger aircraft expected to operate at the Airport through 2025, total aircraft operations at the Airport are forecast to increase marginally from 875,136 operations in 2015 to 885,312 operations in 2025, at a CAGR of 0.1 percent.

Table 4-23 presents historical and forecast landed weight at the Airport through 2025. Total landed weight is forecast to increase at a CAGR of 1.3 percent between 2015 and 2025, from approximately 51.1 million 1,000-pound units to 58.2 million 1,000-pound units.

5. Financial Analysis


This chapter presents the financial framework of the Airport, and the cost and other financial implications following the issuance of the 2016 Bonds and the future bonds necessary to complete the funding of the remaining OMP Airfield Projects and 2016-2020 CIP capital projects described in Chapter 2. Chapter 5 presents the following projections: Operating and Maintenance (O&M) Expenses; Non-Signatory Airline and Non-Airline Revenues; Other Available Revenues, including PFC Revenue and Grant Receipts, and other federal funds; Net Debt Service; the Net Signatory Airline Requirement; and calculation of the Airline Parties' Airport rates and charges. The reasonableness of Airport user fees, including cost per enplaned passenger; and General Airport Revenue Bond (GARB) Debt Service coverage are also discussed.

The GARB debt service included in the financial analysis reflects debt service on outstanding GARBs after the issuance of the 2016 Refunding Bonds and the refunding of certain Airport Obligations, the 2016 New Money Bonds, and future GARBs necessary for funding the OMP Airfield Projects and 2016-2020 CIP capital projects described in Chapter 2. It is expected that annual debt service savings of between $2.1 million and $7.5 million will result from the issuance of the 2016 Refunding Bonds and the refunding of certain Airport Obligations. The expected savings from the 2016 Refunding Bonds have been assumed.

In combination, the 2016 New Money Bonds and future GARBs assumed in the financial analysis reflect the following capital project funding assumptions:
approximately $1.3 billion for remaining OMP Airfield Projects, including $963.5 million for Runway 9C-27C funded with proceeds from the 2016 New Money Bonds and $361.4 million for the extension of Runway 9R-27L funded with future GARB proceeds,
approximately $304.3 million for additional airfield improvements, including $118.0 million for the centralized deicing pad and $186.3 million for cross-field taxiway system and relocation of Taxiways A and B, both funded with proceeds from the 2016 New Money Bonds, and
approximately $773.3 million for the 2016-2020 CIP projects funded with future GARB proceeds.
Financing assumptions of the 2016 New Money Bonds and future GARBs are described in Section 5.5 of this Chapter. Future PFC Revenue Bonds, anticipated to be issued in 2017 to fund approximately $188.6 million of the Terminal 5 Expansion project and to potentially refund certain outstanding PFC Revenue Bonds, are described in Section 5.4.1. of this Chapter.

The other recently announced capital projects, including the Concourse L Extension, Hotel Development, and the Terminal Area Plan, as described in Section 2.2.3 of this Report, are not included in the financial analysis.

i Report of the Airport Consultant

CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT NOVEMBER 3, 2016



While costs for these projects are likely to be incurred during the Projection Period and future bonds could be issued to fund certain portions of the projects with debt service payable during the Projection Period, the projects are in preliminary planning phases and project timing and costs have not been fully developed and are currently unknown.

Anticipated funding sources for these projects are as follows:
Concourse L Extension. To be funded directly by American Airlines.
Hotel Development at the Airport. To be funded through a special facility loan, or loans, backed by hotel revenues.
The Terminal Area Plan is still in the preliminary conceptual planning and discussion phases: Funding sources have not yet, been determined.

5.1 Financial Framework

The Airport is owned by the City, operated by CDA, and is accounted for as a self-supporting enterprise fund of the City on a'Fiscal Year basis. The City's Fiscal Year ends December 31. The City maintains' the books, Records;'and accounts of; the Airport in accordance with ge'nerally'accepted accounting principles ;and as required by the provisions of the Airport Use Agreement and the Senior Lien Indenture. Neither City nor State of Illinois tax revenues are pledged to the payment of- Net Debt Service or to fund the cost of operations at the Airport.

5.1.1 AIRPORT USE AGREEMENT
The Airport Use Agreement sets forth the City's main financial and operational arrangement with the airline tenants of the Airport that are signatory to the agreement (the Airline Parties). The Airport Use Agreement provides, among other things, contractual support of the Airline Parties for GARBs and certain other obligations issued to fund Airport capital improvements. The Airport Use Agreement formalizes the rights and responsibilities ofthe Airline Parties and CDA, and expires on May 11, 2018.

The City has executed the Airport Use Agreement with the following 12 Airline Parties at the Airport: Air Canada, Alaska Airlines, American Airlines, Envoy, Delta Air Lines, Expressjet, FedEx, SkyWest, Spirit, United Airlines, UPS, and Virgin America. In the aggregate, the Airline Parties, including their regional affiliates, accounted for approximately 76.0% percent of the total landed weight at the Airport in 2015. Non-Signatory Airlines, the airlines that are not signatory to the Airport Use Agreement or a regional affiliate to one of the Airline Parties, including foreign flag carriers, accounted for the remaining 24.0% percent of landed weight at the Airport in 2015. Foreign Flag carriers that have signed the International Terminal Use Agreement are referred to as the International Terminal Airline Parties. The Airline Parties and the International Terminal Airline Parties are collectively referred to as the Signatory Airlines in this Report.





Report of the Airport Consultant

CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT



Upon the expiration of the Airport Use Agreement in 2018, the City and the Airline Parties could agree to
execute a new agreement as the result of negotiations between the City and airlines serving the Airport or the
City could elect to impose airline rates and charges without an airport use agreement and in accordance with
the FAA's Policy Regarding the Establishment of Airport Rates and Charges. . -

The City has initiated efforts to evaluate options for a new Airport use agreement that will maximize the use of existing terminal facilities and provide a mechanism for the City to fund future capital projects. While there are multiple rate-setting methodologies that may achieve these goals, in any case, the City is obligated, pursuant to the Senior Lien Indenture, to set airline rates and charges at a level sufficient to pay the net cost of operating, maintaining, and developing the Airport, including the satisfaction of debt service coverage, fund deposit, and payment requirements of the Senior Lien Indenture. Projections of O&M Expenses, Non-Airline Revenues, and Net Debt Service assumed in the financial analysis in this Report are developed independently and material changes to these projections resulting from changes in the airline rate-setting methodology at the Airport are not anticipated.

Although the City is contemplating options for a business deal, the rate-setting methodology after May 2018 is uncertain and remains subject to negotiations between the City and the airlines serving the Airport. Therefore, in developing the financial projections presented herein, a continuation of the rate-setting methodology set forth in the existing Airport Use Agreement was assumed for the entirety of the Projection Period. It is also assumed in this Report that the current Airline Parties and International Terminal Airline Parties will continue to be signatory to future agreements and will remain signatory to those agreements through the Projection Period.

5.1.2 AIRPORT FEES AND CHARGES
Under the current Airport Use Agreement, terminal rental rates and airline landing fees are established using a residual airport rate-setting methodology1, whereby airline rates and charges are calculated to recover any net remaining costs for each Cost-Revenue Center (CRC). To equitably allocate the net cost of operating, maintaining, improving, and expanding the Airport among the Airline Parties, various physical and functional areas of the Airport are separated into CRCs for the purposes of accounting for O&M Expenses, revenues, required fund deposits, and Debt Service on Airport Obligations. An allocable share of the net deficit generated in the Terminal Area, Airfield Area, and Fueling System CRCs is paid by the Airline Parties as part of their Airport Fees and Charges for the use of the Airport. The Airport Use Agreement provides that the aggregate of Airport Fees and Charges paid by the Airline Parties must be sufficient to pay the net cost of operating, maintaining, and developing the Airport (excluding the Land Support Area), including the satisfaction of debt service coverage, deposit, and payment requirements of the Senior Lien Indenture. Airlines or other users of the Airport that are not signatories to the Airport Use Agreement or the International Terminal Use Agreement are assessed Airport fees and charges enacted by City ordinances. For financial




A somewhat modified rate-setting methodology is in effect for portions of the Airfield Area in order to avoid "private business use" under federal tax regulations. See Section 5.7.1 herein


Report of the Airport Consultant

CITY OF CHiCAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT



projection purposes, it was assumed that the City ordinances controlling non-signatory airline fees and charges will remain in place through the Projection Period.

Five CRCs in the Airport's financial structure are included in the residual rate-setting calculation and the adjustment of Airport Fees and Charges, as follows:
• ^ Airfield Area, the Airfield Area includes the aircraft parking areas, runways, taxiways, approach and
runway protection zones, infield areas, navigationalaids, and other facilities related to aircraft taxiing,. . landing, and takeoff.
• Terminal.Area. TheTerrrtinal Area includes the domestic terminal buildings and a designated portion of the-.heating and refrigeration plant.
• Terminal Support Area! The Terminal Support Area includes the public parking facilities, roadways, ' walkways,'automobile rental areas, ground transportation system, and the existing Airport hotel.
International Terminal Area. The International Terminal Area includes the International Terminal and a.designated portion of the heating and refrigeration plant .
Fueling System. The Fueling System includes the tank farm and all facilities that are part of the Airport's hydrant fueling system.

5.1.3 : LAND SUPPORT AREA ¦.'.¦.,.¦¦;.
The revenues and expenses of the Land Support Area are not included in the calculation of Airline Parties' Airport Fees and Charges, or pledged to pay debt senyice on bonds, including the 2016'Bonds. Therefore, the revenues and expenses within the designated Land Support Area are excluded in the financial projections in this Chapter. The Land Support Area includes certain vacant land and air rights and facilities, such as air cargo, hangar;.flight kitchen, and freight forwarding facilities. Principally, these areas and facilities are located on.the perimeter of Airport property.

5.2. Operating and Maintenance Expenses

O&M Expenses include expenses associated with operating and maintaining the Airport, including the airfield, terminal, and landside facilities.

5.2.1 HISTORICAL O&M EXPENSES
O&M Expenses for 2011 through 2015, as presented each year in the City's Airport Comprehensive Annual Financial Report (CAFR) for the years ended December 31, which excludes expenses in the Land Support Cost Center and excludes any expenses associated with certain discretionary funds2 (the Airport Development Fund, Emergency Reserve Fund, and PFC Fund), are presented in Table 5-1.

CHICAGO O'HARE INTERNATIONAL AIRPORT



compound annual growth rate of 3.4 percent, from $407.3 million in 2011 to $466.4 million in 2015. This increase in O&M Expenses can partially be attributed to increasing professional and engineering costs as well as increases in salaries and wages. Between 2011 and 2015, professional and engineering costs increased at a CAGR of 6.2 percent and salaries and wages increased at a CAGR of 4.7 percent. The Airport's contribution of its allocable share of City pension expenses, described in the following section, has contributed to increasing salaries and wages expenses. The expenses shown in Table 5-1 reflect only expenses due and payable in each year (the cash contribution, reflected in the Airport's rates and charges), and do not reflect certain expenses that are not payable in that year, but recorded pursuant to GASB 68 as reflected in the City's Airport CAFR.

O&M Expenses remained relatively level between 2014 and 2015, increasing 0.7 percent, primarily attributable to reductions of snow removal expenses in repairs and maintenance, professional and engineering costs, and other operating expenses, offset by increases in salaries and wages attributable to pension contributions and certain retroactive salary adjustments. Due to the type of expense decreases achieved in 2015 (i.e., snow removal), it is not assumed that decreases similar to those seen in 2015 will occur on an annual basis. Professional and engineering costs decreased 5.5 percent between 2014 and 2015, mainly attributable to decreases in contracted costs. Salaries and wages, including pensions, increased 19.8 percent between 2014 and 2015, and repairs and maintenance costs decreased 10.8 percent between 2014 and 2015 largely because, of the reduction of snow removal expenses. Other operating expenses, which consist of materials and supplies, utilities, insurance, miscellaneous expenses (administrative expenses, telephone, and bad debt expenses), machinery, and vehicles and equipment, decreased by 18.5 percent between 2014 and 2015.

The Airport's O&M Expenses per enplaned passenger from 2011 to 2015 have now decreased at a CAGR of 0.2 percent, from $12.27 in 2011 to $12.15 in 2015, decreasing from $13.25 in 2014 to $12.15 in 2015, attributable to level O&M Expenses and an increase in enplaned passengers in 2015.

5.2.2 CITY PENSION OBLIGATIONS
Pension fund obligations of the Airport are limited to the share of City employee salaries allocated to the Airport; these City employees include both those working directly at the Airport and those from other City departments that support Airport operations such as Purchasing, Finance, and Corporation Counsel. Federal regulations prevent Airport Revenues from being used to fund pension costs for any employees not working directly at or allocated to the. Airport.
The following four pension funds affect Airport expenses:
Policemen's Annuity and Benefit Fund of Chicago (PABF)
Firemen's Annuity and Benefit Fund of Chicago (FABF)
Municipal Employees'Annuity and Benefit Fund of Chicago (MEABF)
Laborers' and Retirement Board Employees' Annuity and Benefit Fund of Chicago (LABF)
The City's pension expenses have increased over time, resulting in an actual cash contribution from the
Airport to City pensions of approximately $25.8 million in 2015. The 2016 Airport rates and charges budget
includes a pension expense of approximately $35.3 million, which is the budgeted amount of the.2016 cash
contribution. The amount budgeted for 2016 reflects the impact of certain pension reforms. Pension .expense
increases projected in this analysis are based on Public Act 099-0506, which was enacted into law.-on- May 30,
2016 This report excludes the impact of Public Act 98-641, which was declared unconstitutional by,the,Illinois
Supreme Court on March 24, 2016. This decision has resulted in expected actual pension expenses in 2016
being below the cash contribution included in the Airport rates and charges budget, however, for purposes of
this Report, the budgeted amount is included in the financial analysis. ..

Due to financial reporting requirements pursuant to the Governmental Accounting Standards Board (GASB), Statement 68, the Airport's 2015 CAFR reflects the total pension liability of $339.5 million. GASB Statement 68, Accounting and Financial Reporting for Pensions—an Amendment of GASB Statement 27, requires the Airport's pension liability to be reported as the portion of the present value of the total pension liability, defined as the projected benefit payments to be provided through the pension plan to current active and inactive employees that is attributed to those employees' past periods of service, less the amount of the pension plan's fiduciary net position.3 Under the current provisions of .the Pension Code, MEABF and LABF are projected by their respective actuaries to have insufficient funds available to make payments to beneficiaries beginning in Fiscal Years 2025 and 2027, respectively. Although it is uncertain how such payments would be made in this circumstance, one possibility is that the City could be required to make these payments due to beneficiaries on a pay-as-you-go basis, which would cause a significant increase in the City's contributions and, as a result, to the Airport's allocated portion of such contributions to such funds. Assuming the current allocation percentage of this requirement to the Airport, pension expenses are estimated to increase at a CAGR of 10.9 percent from approximately $35.3 million budgeted in 2016 to approximately" $89.4 million in 2025, should the City be required to make such beneficiary payments in addition to its required contributions.

BUDGETED AND PROJECTED OPERATING AND MAINTENANCE EXPENSES

Actual O&M Expenses vs Budget
CDA sets a budget for airline rates and charges annually using the rate-setting methodology set forth in the Airport Use Agreement, as described in Section 5.1 above, based on the budgeted O&M Expenses, Non-Airline Revenues, required fund deposits, and debt service on Airport Obligations. As shown in Table A-1 of Appendix A to this Report, between 2011 and 2015, actual O&M Expenses for the Airport have been less than the budgeted amount in each of the last 5 years, averaging 5.7 percent below budget. The Airport's 2016 final airline rates and charges budget serves as the base from which O&M Expenses are projected.

Exhibit 5-2 presents the 2016 budgeted O&M Expenses by cost category.

NOTE: Includes Land Support . ig$j - -A-Vr ¦ SOURCE: Chicago Department of Aviation, August:2016. PREPARED BY: Ricondo & Associates, Inc, September 2016.

O&M Expenses are classified into the following, categories:, Personnel
Personnel expenses include compensation for City staff working at the Airport, pension obligations discussed above, and an allocation of personnel costs from other City departments that support Airport operations, such as Purchasing, Finance, and Corporation Counsel. Personnel expenses associated with Airport operations and capital development are projected to increase 6.0 percent in 2017, based on operational and future development needs. Personnel expenses are then projected to increase at an annual rate of 4.0 percent from 2018 through the Projection Period, attributable primarily to salary increases, escalating insurance premiums, and other benefits increases. When the assumed additional personnel expenses related to additional pension obligations and future capital projects are incorporated, personnel expenses are projected to increase at a CAGR of 5.6 percent through 2025.

Repairs and Maintenance
Repairs and maintenance expenses at the Airport include the cost of outside contractors that provide ramp repair, taxiway painting, outside janitorial services for terminals, heating and air conditioning, trash removal, escalator/elevator maintenance, and miscellaneous repairs. Repairs and maintenance expenses are projected to increase at a CAGR of 4.75 percent through 2025, primarily reflecting inflation and additional costs associated with maintaining existing aging facilities. When the assumed additional repairs and maintenance expenses related to future capital projects are incorporated, repairs and maintenance expenses are projected to increase at a CAGR of 5.0 percent through 2025.




Report of the Airport Consultant

Energy
Energy costs include gas, water, electricity, and fuel oil required to operate the Airport. Energy costs are projected to increase at a CAGR of 4.5 percent. However, when the assumed additional energy expenses related to future capital projects are incorporated, energy expenses are projected to increase at a CAGR of 4.6 percent through 2025

Materials and Supplies
Materials and supplies expenses include costs associated with the purchase of deicing fluid, office supplies, cleaning supplies, keys and locks, and other general maintenance supplies for the Airport. Materials and supplies expenses are projected to increase annually at the 3.0 percent rate of inflation. When the assumed additional material and supply expenses related to future capital projects are incorporated, expenses for materials and supplies are projected to increase at a CAGR of 3.6 percent through 2025.

Engineering and Professional Services
Engineering and professional services expenses include fees for specialized engineering, legal, and other technical services. These expenses aTe'^pT^jec'ted to increase annually at a CAGR of 4.5 percent through 2025, primarily because of increases in billing rates. Engineering and professional services expense projections include an additional $2 million annually in 2017 and 2018 to reflect additional services in those years for future capital planning and negotiating a new Airport Use Agreement. The use of outside professional services was otherwise assumed to remain constant through 2025. The assumed additional engineering and professional services expenses are projected to increase at a CAGR of 4.9 percent through 2025.

Other Operating Expenses
Other operating expenses include equipment and property rentals, insurance, miscellaneous expenses (administrative expenses, telephone and bad debt expenses), machinery, and vehicles and equipment. Equipment and property rental expenses include expenses related to the rental of heavy equipment and contracting of equipment operators, rental of unarmed security systems, operation of the automated transit system, shuttle bus services, rental of office equipment, and lease of a warehouse. Other operating expenses are projected to increase at a CAGR of 5.9 percent through 2025, primarily reflecting inflation, the need to replace various equipment, and additional expenses related to future projects.

O&M Expenses Related to Remaining OMP Airfield Projects
Incremental effects on O&M Expenses from Runway 9C-27C construction and the extension of Runway 9R-27L OMP Airfield Projects are expected to result from the increased operation and maintenance required to maintain the additional airfield pavement and are estimated to begin in 2021. Projections of these O&M Expenses were developed based on the incremental increase in runway pavement surface area in the Airfield Area with Airfield Area O&M Expenses projected to increase $4.9 million in 2021 and $9.6 million in 2022, the first full year of operation. This projected increase in Airfield Area O&M Expenses is proportionate to the increase in runway square footage, which represents a conservative approach, particularly given that new infrastructure projects do not typically have major maintenance needs immediately after completion.

5.3 Non-Signatory Airline and Non-Airline Revenues

Non-Signatory Airline Revenues are revenues collected from airlines that are not parties to the Airport Use Agreement or International Terminal Use Agreement. Non-Airline Revenues consist of those Revenues generated at the Airport from sources other than airlines (e.g., automobile parking, rental cars, restaurants, news and gifts).


Report of the Airport Consultant
CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT



A majority of the Airport's Non-Airline Revenues are generated from concessions, which includes automobile parking revenues. Table 5-2 presents concession revenues at the Airport from 2011 through 2015. As shown, concession revenues were approximately $211.9 million in 2011, and increased to approximately $244.0 million in 2015, reflecting a. CAGR of 3.6 percent during that period. The increase from 2011 through 2015 resulted from the ongoing recovery from the economic recession,.as well as continually enhanced concession offerings at the Airport, with local and national favorites well represented. Parking revenues, which represent the Airport's largest Non-Airline Revenue source, were $96.0 million in 2011, and have increased to $99.2 million in 2015, reflecting a CAGR of 0.8 percent.

These revenues are discussed below.

CICA TEC
CICA TEC operates and maintains certain common-use equipment, including baggage systems and loading bridges, for the airlines serving the International Terminal. CICA TEC was formed by the foreign-flag carriers that operate at the International Terminal together with United Airlines and American Airlines, which also operate international arriving flights at the International Terminal. Lease payments by CICA TEC to the City

are considered Non-Airline Revenues. CICA TEC lease payments are budgeted at $14.4 million in 2016 and are projected to increase at a CAGR of half the rate of expected inflation (1.5 percent) through 2025.
Concessions
Concession revenues include those derived from the concessionaires in the terminal, such as restaurants and news and gift shops, and the Airport's landside operations such as automobile parking, automobile rentals, and bus service. CDA is continually looking for additional space that could be allocated to concessions and at opportunities to enhance concession revenue.
Actual Concession Revenues vs. Budget
As shown in Table A-2 of Appendix A to this Report, between 2011 and 2015, actual concession revenues generated at the Airport have been higher than the budgeted amount in 3 of the 5 years presented, averaging 2.2 percent higher"than budgeted. "Actual concession revenues have been within 1 percent of budget in each of the past 3 years. The Airport's 2016 final rates and charges budget serves as the base from which concession revenues are projected.

5.3.2.4 Automobile Parking Revenues. ''
The City ria's a management agreement'with Standard Parking Corporation, a provider of parking facility management services. Under the agreement, Standard Parking Corporation provides personnel to operate and maintain the parking facilities at the Airport, provides cashier services, and provides ground transportation. The current 5-year contract between the City and'Standard Parking commenced-January 1, 2013. Standard Parking: receives-a fixed management fee adjusted annually by: a pre-agreed::upon contract • rate and submits daily, monthly/and annual accountings to'the CDA. Budgeted parking revenues net of City taxes for 2016 are $101.5 million, or 39.1 percent of concession revenues.

Parking revenues at the Airport are a function of on-Airport parking'demand and the availability of parking1 spaces demanded. Several.factors affect onrAirpprt parking.demand, sucb.,as:
The Airport currently offers hourly, and daily .parking in the ?,300rspace, .Terminal Parking. Garage,,., with a

Alternative transportation options include the CTA Blue Line Train providing direct access to a station located in the Terminal and connectivity between downtown Chicago and other CTA train lines. According to the CTA, ridership on the Blue Line has been increasing steadily over the past 15 years and has reached record levels, with the highest transit ridership of any U.S. Airport. Despite this growth, Airport parking revenues have also grown over this period. The City continues to evaluate the feasibility of a third-party operated express airport train service, which could provide direct non-stop service between the Airport and downtown Chicago. This express service, if constructed, may impact parking demand at the Airport, but that impact is unknown.

However, TNCs .offer, a relatively. new. and increasingly popular transportation alternative that may impact on-Airport parking revenues. On November 24, 2015, TNCs secured permission from the City to offer TNC service at the Airport, and while TNCs may have been servicing the Airport before that time without permission, given the recent emergence of TNCs, there is not sufficient data available to meaningfully assess the degree to which they are capturing demand share at the expense of on-Airport parking or other forms of ground transportation such as taxis and mass transit options. The impact of TNCs to on-Airport parking revenues will be clearer as the industry matures and tracking of TNC activity at airports improves.
As Airport passengers are forecast to increase over the Projection Period, as discussed in Chapter 4 of this Report, it is assumed that on-Airport parking demand will also increase at a rate consistent with the increase in enplaned passengers. Increased on-Airport parking demand over the Projection Period could create parking capacity issues at the Airport. To accommodate future demand, the City is currently constructing the Multimodal Facility which will include approximately 2,000 parking spaces with direct access to the ATS, and has planned a new parking garage as part of the Airport's capital program. The Multimodal Facility, expected to be completed at the end of 2018, will accommodate demand for mid-market parking. The planned parking garage construction will provide customers typically parking in the Terminal Garage another option to optimize their level of convenience. Additional information regarding these capital projects is included in Chapter 2 of this Report.
An increase in parking rates at the Airport requires approval by the City Council, and while currently there are no proposed rate increases under City Council review, CDA may elect to seek approval from City Council for parking rate increases on existing facilities and to set parking rates on new facilities opened during the Projection Period. Parking rate increases would likely result in increases in parking revenues to the Airport. The last parking rate increase was implemented on January 1, 2012.
For purposes of this Report, parking revenues are projected to increase at a CAGR of 2.5 percent through 2025, which is a combination of increases in the number of OtkD passengers and assumed periodic parking rate increases, based on historical parking rate increases at the Airport, to account for inflation (3.0 percent every other year). Over the past 10 years, parking rates at the Airport for the Terminal Garage and economy lots have increased at a CAGR of 1.8 percent and 2.7 percent, respectively, excluding parking rate increases
related only to tax increases.

National brands; and The Hertz Corporation operates the Hertz, Dollar, and Thrifty brands. Advantage operates as an independent brand.

A Consolidated Rental Car Facility Lease and License Concession Agreement, executed in 2013 by the rental car companies that will serve the Airport from the Multimodal Facility, establishes a Minimum Annual Guarantee Fee and Concession Fee, which will be the greater of the Minimum. Annual Guarantee Fee or lO percent of annual gross revenues, as'defined in the agreement:! At the end of each agreement year, an annual reconciliation will be computed for underpayment/overpayment. Budgeted automobile rental revenues-for.2016 are $26.9 million, or 10.4 percent of concession revenues. Automobile rentals are projected to increase at a CAGR of 2.3 percent through 2025, which is a combination of increases in the number of O&D passengers and half the rate of inflation.

Restaurants
Concessionaires operate more than 100 restaurants/food and beverage outlets in the domestic terminals at the Airport. These outlets include a mixture of. national and local Chicago brands. The terms of the agreements for these concessionaires generally range from 5 years to 10 years. The City receives from the concessionaires a percentage of gross sales, .against minimum annual guarantees that are adjusted annually based on the previous year's sales. . The budgeted domestic terminal restaurant revenues for 2016 are $50.1 million, or 19,8 percent of concession revenues. Domestic terminal restaurant revenues are projected to increase at a CAGR of 2.3 percent through 2025, which is a combination of increases in the number of domestic enplanements and increases based on anticipated new offerings during the Projection Period.

In 2015 the Airport opened 21 new and refurbished stores. The new concepts included: Coach, MAC, and Chicago Sports Pop Up. The refurbished stores included one Starbucks, two McDonalds and others. In 2016 the Airport has completed seven new concepts including: Sarah's Candies, Green Market, Publican, and Summer House.

News and Gifts
Hudson Group operates 24 news and gifts outlets in the domestic terminals. The City receives, from Hudson Group, a percentage of gross sales against minimum annual guarantees that are adjusted annually based on the previous year's sales. The budgeted domestic terminal news and gifts revenues for 2016 are $24.3 million, ¦ or 9.6 percent of concession revenues. News and gift revenues in the domestic terminal are projected to increase at a CAGR of 2.2 percent through 2025, which is a combination of increases in the number of domestic enplanements and half the rate of inflation.

International Terminal Concessions
Effective September 1, 2011, the CDA executed a 20-year concession agreement with Westfield Group to enhance the concessions in the International Terminal. Under the International Terminal concession agreement, Westfield completed a $26 million renovation that included the addition of 24 new dining and retail outlets, including 11 local Chicago brands; a redesigned TSA checkpoint; a new dining lounge and new bathrooms; and new seating, lighting, signage, and fixtures throughout the Internationa! Terminal. The

renovation also included the addition of a 10,000-square-foot flagship duty-free store, through which all departing travelers must now pass after clearing the TSA security screening checkpoint.

Under the previous concession agreement for the International Terminal, concession sales were approximately $25.0 million annually. Under the new agreement, concession sales increased 84.8 percent to $46.2 million in 2015. These sales generated approximately $7.2 million in revenue for the Airport, more than double the revenue in 2010, the last year prior to the start of the redevelopment. This increase in concession sales has resulted in additional revenue to the Airport, and is a result of a re-engineered layout as well as an improved selection of offerings. Prior to redevelopment, the terminal's first since its 1993 construction, 95 percent of concessions were located pre-security, preventing passengers from making purchases while waiting for flights. Of the 15 new retail and 9 new dining destinations in the newly redesigned terminal, 22 are located post-security to serve travelers near their gates. CDA has indicated that it is reviewing elements of the International Terminal concession agreement that might be used to improve domestic terminal concession operations.

The budgeted International Terminal concession revenues for 2016 are $10.8 million, or 4.3 percent of concession revenues. International Terminal restaurant revenue is projected to increase at a CAGR of 4.5 percent through 2025, which is a combination of increases in the number of international'enplanements and the rate of inflation. News and gift revenue in the International Terminal is projected to increase at a CAGR of 3.0 percent through 2025, which is a combination of increases in the number of international enplanements and half the rate of inflation. Duty Free revenue in the International Terminal is projected to increase at a CAGR of 3.0 percent through 2025, which is a combination of increases in the number of international enplanements and half the rate of inflation.

Display advertising
Display advertising revenue is budgeted to be $19.1 million in 2016 and is projected to remain level through 2025.

Hotel
Hotel revenue is budgeted to be $7.8 million in 2016 and is projected to increase at a CAGR of 2.3 percent through 2025. As described in Chapter 2, the total investment for the three hotel development projects at the Airport is estimated to be approximately $350 million and is planned to be funded by a special facility loan backed by hotel revenues. Requests for Proposals for an Operator Agreement for the terminal hotels and for a Development Agreement for the mixed-use commercial development are expected to be issued in the fall of 2016; however, the financial analysis does not assume any impacts associated with the hotel redevelopment projects on future hotel revenues or the use of hotel revenues on payments of a special facility loan.
Of/?er Concessions
Other concessions include revenues from bus service, miscellaneous, retail gift shops, currency exchange/ATMs, wireless, and telecommunications. Other concessions revenues are budgeted to be $15.1 million in 2016 and are projected to increase at a CAGR of 1;8 percent through 2025.

5.3.2.6 Concessions Planning ¦'¦
The City is making efforts to maximize concession revenue's through strategic planning. These efforts include both near-term and long-term planning at the Airport, as well as space and vendor management.

Plans involving the renegotiation and remarketing of the current concession agreements expiring in the near term should yield an increase in overall concession revenue through the issuance of new contracts. The City is also maximizing the use of terminal' space to" increase' concession' revenue. A combination of CDA terminal space and space that was released by airlines is planned to be converted into concession space that will also allow for increased revenues. Ah improvement1 in overall concessions planning was reflected in the issuance of a hew long-term concession' 'agreement in the International Terminal, which provided opportunities for vendors to'maximize their investments' and 'yielded increased concession'revenues. The financial analysis presented in this chapter 'doesriot ihclucle the'potehtiaf effeds of planned concession initiatives in the Domestic Terminal.

5.3.2.7 " Reimbursements and Other Non-Airline Revenue
Reimbursements primarily.relate.fo utilities. Many of the buildings on Airport property are separately metered for utilities; however,,.CDA.pays, the.utility., companies directly. .CDA then bills each tenant for individual metered usage at regular scheduled rates that are no higher than the rates paid by CDA itself. Other revenue items, included in this line item are CICA TEC energy reimbursement (CICA TEC's energy payments .to the City) and . interest income. These revenue items, are, not affected by, increases or decreases in aviation activity; increases are based on inflation. Other Non-Airline Revenues include interest income. Reimbursements and other Non-Airline Revenues combined are projected to increase at a CAGR of 1.3 percent through 2025.

Non-Airline Revenues, shown on Exhibit .5-6, are projected on the basis of a review of historical trends, projected air carrier activity levels,'and inflation. Non-Airline Revenues are projected to increase at a CAGR of 2.1 percent between 2016 and 2025.

Land rentals for hangar and cargo facilities are allocated to the Land Support Area. As described in section 5.1.3, these revenues are used to offset expenses incurred in the Land Support Area and are not Revenues or pledged as security for GARBs, including the 2016 Bonds. Therefore, these revenues are not included in the projections.

Non-Airline Revenues Related to Future Projects
OMP Airfield Projects are not expected to directly affect Non-Airline Revenues, although these projects are expected to increase Airport capacity, thus allowing for additional enplanement growth, which would indirectly increase concession revenues at the Airport. There are also no assumed effects on Non-Airline Revenues associated with the future capital projects described in Chapter 2 of this Report, including the 2016 Projects.

5.4 Other Available Revenue

5.4.1 PASSENGER FACILITY CHARGE REVENUE
The City has FAA approval to impose a PFC at the Airport and to use PFC Revenue for approved Airport projects, including OMP Airfield Projects.

PFC Program Highlights
The City collects a $4.50 PFC per eligible enplaned passenger less an $0.11 airline processing charge. No increase in the PFC collection level was assumed in the projections. No decrease in the PFC collection level is required based on current PFC approvals.
• The City has approved authority from the FAA to impose a PFC and use PFC Revenues for all project costs anticipated to be funded with PFC Revenues for OMP Phase 1, OMP Phase 2A, and the remaining OMP Airfield Projects.

The Series 2011A Bonds through maturity and, through 2018, the Series 2008A Bonds and the Series 2010F Bonds, and any bonds refunding all of those bonds, are secured not only by a pledge of Revenues, but are also payable from and secured by a pledge of available PFC Revenues. The City is evaluating the use of PFC Revenues after calendar year 2018 and in its sole discretion plans to continue to use PFC Revenues to pay debt service on the Series 2008A Bonds and Series 2010F Bonds, or on any bonds refunding those bonds, for which the City is under no obligation to use PFC Revenues. Therefore, the financial analysis in this Report assumes that PFC Revenues will be applied to pay debt service on the Series 2008A and Series 2010F Bonds; br on'any bonds refunding those' bonds, from 2019 through the end of the Projection Period.
PFC Revenues will be pledged as Other Available Moneys to the 2016F New Money Bonds through the Projection Period.
The City is in the process of submitting a PFC application to the FAA to apply for PFC authority for the Terminal 5 Expansion project described in Chapter 2 of this Report. PFC Revenue Bonds are expected to be issued in 2017 to fund approximately $188.6 million of the Terminal 5 Expansion project costs and to potentially refund certain outstanding PFC Revenue Bonds. Debt service on these future PFC Revenue Bonds is assumed to be approximately $12.3 million annually through the Projection Period. Due to the uncertainty of outstanding PFC Revenue Bonds to be refunded with the 2017 PFC Revenue Bonds, no savings are assumed in this Report. Additional Terminal 5 Expansion project costs could be determined to be PFC-eligible based on project refinements, if so; the City may elect to use PFC Revenues to fund those costs.
Projected PFC Revenues, as shown on Exhibit 5-7, are expected to be sufficient to cover all PFC Revenue Bond debt service and the PFC Revenues pledged to pay PFC-backed GARB debt service at the current PFC collection level of $4.50 per PFC-eligible enplanement. If PFC Revenues generated in a given year are insufficient to fully pay PFC-backed GARB debt service in that year, then the City may elect to use existing PFC Revenues in the PFC Revenue Fund, if available, instead of Airport Revenues to pay the shortfall.

5.4.2 FAA AIRPORT IMPROVEMENT PROGRAM GRANTS AND OTHER FEDERAL FUNDING
As of August 2016, the City has received $505 million of the $925 million multiyear LOI grants awarded ($300 million under grant AGL-06-01 and $625 million under grant AGL-10-01, as amended) by the FAA for OMP Phase 1, OMP Phase 2A, and the remaining OMP Airfield Projects.

On November 21, 2005, the FAA issued an LOI (AGL-06-01) to the City for $300 million in discretionary grants for OMP Phase 1 over a 15-year period from Federal Fiscal Years 2006 through 2020.

A total of $160 million of the OMP Phase 1 LOI discretionary grant is pledged to the payment of debt service on the Series 2011B Bonds, with the other $140 million used on a pay-as-you-go basis.
As of August 2016, the City has received $220 million of the $300 million Phase 1 LOI discretionary grant, of which, $80 million has been applied to date to the payment of debt service on the Series 2011B Bonds.
• The remaining $80 million of the OMP Phase 1 LOI grant, anticipated to be received by the City in four annual $20 million installments through 2020, is pledged to the payment of debt service on the Series 2011B Bonds. The 2016 Refunding Bonds are anticipated to be used to refund certain

All future LOI grant installments anticipated to be received by the City are assumed to be made available by the FAA and paid to the City in accordance with the schedule shown in Table B-4 in Appendix B of this. Report.

Under the AIP, in addition to discretionary grants, the City also receives annual entitlement grants for use at the Airport based on the number of enplaned passengers and cargo tonnage at the Airport.

Federal funding received by the Airport, and aviation operations in general, could be adversely affected by implementation of the sequestration provisions of the Budget Control Act, which was signed into law by the President on August 2, 2011. Under the budget .sequestration provisions, the Build America Bonds (BAB) subsidy, which is applied to offset debt service paid by the airlines on the Series 2010B Bonds, was reduced by 7.2 percent for Federal FY 2014, 7.3 percent for Federal FY 2015, and 6.8 percent for Federal FY 2016, and will be reduced by 6.9 percent for Federal FY 2017. Absent, Congressional action, the sequester will continue through Federal FY 2025; however, the percentage of future reduction is not known at this time. The amount of the BAB subsidy in 2016 is budgeted to be $12.4 million; for purposes of the financial analysis in this Report, this amount is assumed to be available in each year of the Projection Period.

Projected annual Net Debt Service, net of capitalized interest, PFC Revenues, Grant Receipts and other federal funds used to pay debt service, on all currently outstanding GARBs and projected future GARBs is discussed in this section. Projected debt service is provided in Table B-5 in Appendix B of this Report.

Outstanding GARB Debt Service after the Issuance ofthe 2016 Refunding Bonds
Total outstanding GARB debt service totals approximately $540.7 million in 2016. The expected savings from the 2016 Refunding Bonds are assumed. After the issuance of the 2016 Refunding Bonds and refunding of certain Airport Obligations, outstanding GARB debt service is projected to increase to approximately $568.9 million in 2018 then decrease steadily throughout the Projection Period to approximately $452.9 million- in 2025.

2016 New Money Bond Debt Service
As described in Chapter 2 of this Report, the 2016 Projects include the construction of Runway 9C-27C and enabling projects, centralized deicing pad, and cross-field taxiway system and relocation of Taxiways A and B. Proceeds from the 2016 New Money Bonds are anticipated to be used, in part, to fund the 2016 Projects. The 2016 Projects total approximately $1.3 billion, of which approximately $1.0 billion will be funded with proceeds from the 2016 New Money Bonds. PFC Revenues and Grant Receipts from a FAA LOI Grant, both used on a pay-as-you-go basis, are anticipated to fund the portions of the 2016 Projects not funded with the 2016 New Money Bonds.

In addition to Revenues, the Series 2016E New Money Bonds are also payable from and secured by a pledge of Net Grant Receipts. The City anticipates receiving annual FAA LOI Grant reimbursements in the amounts shown in Table 5-3, which will be used to pay debt service on the 2016E New Money Bonds in the year following the receipt of the grant.

In addition to Revenues, the Series 2016F New Money Bonds are also payable from.and-secured by a pledge of PFC Revenues through maturity.
The 2016 New Money Bonds are each assumed to have a term of 35 years, and for purposes of this Report, interest on the 2016 New Money Bonds is assumed at the current market interest rate as of September 7, 2016 plus 75 basis points.

Total debt service payable on the 2016 New Money Bonds is projected to be approximately $9.1 million in 2017, decrease to $8.8 million in 2018, then increase to approximately $42.9 million in 2019 and 2020, approximately $62.2 million in 2021 and 2622, and then increase to approximately $92.2 million through the end of the Projection Period, based on the expected timing of project components being completed;and the anticipated structure of the 2016E New Money Bonds. ''

Net Debt Service on future GARBs :
The financial analysis presented in this chapter includes Net Debt Service on future GARBs to be issued to fund the Airport's capital program described in Chapter 2 of this Report and includes the following:
Future Remaining OMP Airfield Projects GARBs. Approximately $361.4 million of the remaining OMP Airfield Projects are estimated to be funded by proceeds from future 'GARBs. Funding" approval for the extensidnbf Runway 9R-27L has yet to be negotiated with the Airline Parties and Airline Party approval''Has riot' yet been' requested 'or'deceived for'"these' Bonds.' Based ori'the" City's 'planned schedule for the remaining'OMP Airfield Projects, Net Debt Service! net of capitalized'interest,' for these GARBs is assumed to be approximately $42.8 million in 2022 arid then remain level through the Projection Period.
Future 2016-2020 CIP GARBs. As shown in Chapter 2 of this Report, proceeds from future GARBs in the amount of approximately $773.3 million, along with other funds, are needed to fund the Airport 2016-2020 CIP. Based, on the anticipated timing of capital expenditures and anticipated future Mil airline approvals, a bond issuance in FY 2018 is assumed in this,financial analysis; shown below. Debt service on these bonds is allocated to cost centers based on the type of capital projects funded, detailed in Chapter 2. Net. Debt Service on these future bonds is projected to be approximately $38.9 million in 2019, and then to steadily increase as . projects included .in the 2016-2020 CIP are completed, to approximately $73.5 million in 2025.
The Terminal Area Plan, described in Section 2.2.3 of this Report, is still in preliminary planning and discussion phases, and due to the uncertainty of project costs, funding, and timing, no future GARB issuances associated with this project have been assumed, however debt service payable during the Projection Period is expected.
The future GARB issuances all assume 30-year bonds and an interest rate of 6.5 percent. GARB issuances associated with the remaining OMP Airfield Projects each assume capitalized interest until the completion the extension of Runway 9R-27L, assumed to be October 2021. The GARB issuance associated with the 2016-2020 CIP assumes capitalized interest until individual project completion. The year and amounts assumed are as follows in Table 5-4.

5.7 Calculation of Airline Parties' Airport Fees and Charges

Under the Airport Use Agreement and the International Terminal Use Agreement, the Airfield Area, the Terminal Area, .the International Terminal Area, and the Fueling System each generate rentals, fees, or charges payable by the airlines that are signatory to such agreements. The Airport Fees and Charges presented in this section for 2016 through 2018 reflect the rate-setting methodology in the Airport Use Agreement and the International Terminal Use Agreement. In the financial projections presented herein, a continuation of the current Airport residual rate-setting methodology was assumed through 2025; see Section 5.1.1 of this Chapter.

Applicable Non-Airline Revenues (i.e., rentals, concession revenues, and reimbursements), as well as the following costs, are allocated to each CRC to calculate applicable rates used to generate such fees, rentals, and charges:
O&M Expenses. Includes the O&M Expenses (direct and allocated indirect) attributable to the CRC:
• Net Debt Service. Includes the portion of debt service, net of capitalized interest, and debt service coverage attributable to the CRC. The debt service amounts included in the calculation of airline rates and charges also reflect certain adjustments required to be made to actual debt service under the Airport Use Agreement for the purpose of calculating of Airport Fees and Charges.
Fund Deposit Requirements. Includes the allocated portions of the amounts required to be deposited to the funds described earlier.

5.7.1 AIRFIELD AREA
Generally, Landing Fees are calculated by first determining the net cost of the Airfield Area, which consists of portions of the following: sum of O&M Expenses, Net Debt Service, fund deposit requirements, and the net deficit of the International Terminal Area less the sum of projected Non-Airline Revenues and net revenues of the International Terminal Area. The Net Cost of the Airfield Area is allocated among Signatory and Non-Signatory Airlines on the basis of the approved maximum landed weight of all aircraft. Each Signatory Airline and Non-Signatory Airline pays Landing Fees on the basis of the ratio of its total approved maximum landed weight to the total approved maximum landed weight of all Signatory Airlines and Non-Signatory Airlines. The landed weight of aircraft landed by certain classes on Non-Signatory Airlines may be increased by Non-Signatory Airline premium factors to be determined by the City's Commissioner of Aviation from time to time.

In order to avoid "private business use" of the Airfield Area under federal tax law, certain modifications to the rate-setting methodology described in the preceding paragraph have been in effect since November 2005. The purpose and effect of these modifications are to cause the Airline Fees and Charges paid by the Airline Parties relating to their use of the Airfield Area to be computed without regard to deficits or surpluses relating to the use of the Airfield Area by entities other than the Airline Parties.

Exhibit 5-11 presents the Projected Landing Fees at the Airport during the Projection Period

TERMINAL AREA
O&M Expenses, Debt Service; and fund deposit requirements allocated to the Terminal Area' are added together and offset by Nbri-Airline Revenues arid Non-Signatory Airline Revenues attributable to the Terminal Area. A portion ofthe Terminal:Suppoft Area net deficit or net revenue is then allocated to'the Terminal Area to yield the Terminal Area net deficit! The Terminal Area net'deficit-is paid by the Airline Parties in the form of Terminal Area Use Charges, which are calculated on a per square foot of exclusive or preferential use leased space basis. In addition to the Terminal Area Use Charges/ the Airport Use Agreement establishes a $5.00 per square foot Terminal Area Rental rate for space exclusively or preferentially leased to the Airline Parties.
INTERNATIONAL TERMINAL AREA
The International Terminal Use Agreement creates sub-cost centers (the Exclusive Use Cost Center, the Enplaned Common Use Cost Center, and the Deplaned Common Use Cost Center) within the International Terminal Area. The International Terminal Airline Parties pay terminal rentals and common use charges based on their use of the International Terminal Area.
Portions of O&M Expenses, Net Debt Service on GARBs, and Non-Airline Revenues are allocated to the sub-cost centers, as appropriate, and a portion ofthe Terminal Support Area net deficit or net revenue is allocated to the International Terminal Area under the Airport Use Agreement. These sub-cost center expenses are generally allocated on the basis of the relative square footage of the respective sub-cost centers, yielding a net requirement for each sub-cost center.
The net requirement of the Exclusive Use Cost Center results in a base terminal rental rate according to leased square footage; the net requirement of the Enplaned Common Use Cost Center results in a base common use charge rate according to the number of International Terminal enplaned passengers; and the net requirement of the Deplaned Common Use Cost Center results in a base common use charge rate according to the number of International Terminal deplaned passengers.
Exhibit 5-12 presents the projected terminal rental rates in the Domestic Terminal and International Terminal at the Airport during the Projection Period.

5.7.4 FUELING SYSTEM
The net cost of the Fueling System consists of the portions of O&M Expenses and Net Debt Service allocated to the Fueling System. Of this net cost, 10 percent is shared equally by all Airline Parties and International Terminal Airline Parties. The remaining 90 percent of the net cost is divided by the total gallons of fuel distributed from the Fueling System and charged to airlines based on the number of gallons used by each airline. -

5.8 Reasonableness of Airport User Fees

Table B-9 in Appendix B at the end of this Report presents the airline revenue resulting from the previously described rentals, fees, and charges. Consistent with the Airport Use Agreement and International Terminal Use Agreement, the total Signatory Airline revenue presented in Table B-9 equals the Net Signatory Airline Requirement presented in Table B-7.

5.8.1 AIRLINE COST
A general test of the reasonableness of airport user fees is to compare projected airline costs in a manner that accounts for airline activity. One approach is to measure airport user fees on a per enplanement (CPE) basis. By comparing this metric on a year-over-year basis and by comparing it to airlines' revenue and estimated costs allocated to the Airport, the reasonableness of Airport user fees can be determined. The airline CPE is calculated by dividing the Total Airline Requirement by the number of enplaned passengers at the Airport.

Exhibit 5-13 shows the projected.airline CB.E,atrthe Airport. As.shown,,the CPE is projected to.increase from $17.49 in 2016 to $25.38 in 2025, which equates to $19.45 in 2016 dollars assuming 3 percent inflation. Notable increases include the following:
• 2017 through 2025 - Incremental increases in CPE associated with City pension contributions.
• 'i 2017 through 2025,- Incremental increases in airline requirement associated with Net Debt Service on W2016 New M6hey;Bbhds as. well as as'sumecl'future GARB.issuances to fund the Airport 2016-2020 CIP

SOURCES: City of Chicago Department of Aviation; Ricondo & Associates, Inc., based on the analysis and assumptions in the Report November 2016. PREPARED BY- Ricondo & Associates, Inc., November 2016.

The projected Airport user fees shown in Exhibit 5-13 are evaluated in this analysis to be reasonable based on the expectation that these fees will not deter forecasted demand for air traffic at the Airport as airlines continue to deploy capacity to airports based on available resources. The projected Airport user fees in this analysis are deemed to be reasonable based on the following combination of factors:

Large population and strong economic base - The Airport is located in the third-most populous metropolitan region in the United States and is ranked fourth in the nation in terms of domestic O&D passengers in calendar year 2015 - following the New York, Los Angeles, and San Francisco markets. The Airport's Air Trade Area has a large, diverse economic base that supports business and leisure

CITY OF CHICAGO

travel. Projected economic variables indicate that the Air Trade Area will remain a destination that
attracts both business and tourist visitors, positively affecting the demand for future inbound airline
travel. Projected Air Trade Area economic variables further support the continued growth of local
outbound passengers. . . .
•Attractive geographical location - The Airport's central location arid proximity to heavily traveled east-west airways make it a natural location for airline hub activities and is complementary to airline route networks.
Important hub for United and American - The Airport is a major connecting hub.for United and American within their United States domestic route networks, and it is an important international gateway for European, Asian and Canadian passenger traffic, providing strong connectivity to flights of international alliance partners. As estimated in Section 4.1 of this Report, the Airport is the second highest contributor to profit for United and the fourth highest contributor to profit for American. The Airport is also an increasingly important airport within the route networks of several United States low-cost carriers. Generally, Airport user fees are not a key contributor to airline's profitability in the United States.
Increases in debt are associated with capital projects that allow for growth - Airport user fees during the Projection Period are calculated to recover debt service and operating costs partially attributable to significant capital projects designed to provide capacity at the Airport which supports the ability for airlines to increase service. Although the funding of these projects is anticipated to result in increased Airport user fees, these projects support projected long-term growth at the Airport.
In summary, Airport user fees, although increasing over the Projection Period, are one of many factors that are considered by airlines when evaluating air service. Airport user fees were approximately 6.7 percent of system-wide total airline operating costs according to the airline industry group Airlines for America'' and are one of many factors airlines consider when allocating capacity resources. Forecasted growth of population and economic base, along with the geographical location and established role of the airport in airlines' route network, support the reasonableness of projected Airport user fees.

5.9 General Airport Revenue Bond Debt Service Coverage

Table B-ll in Appendix B at the end of this Report presents the Debt Service coverage ratios projected for GARBs from 2016 through 2025. As contained in the Senior Lien Indenture:

The City covenants... [that it will] fix and establish, and revise from time to time whenever necessary, the rentals, rates and other charges for the use and operation of O'Hare and for services rendered by the City in the operation of it in order that Revenues in each



2 1 percent of passenger airline operating expenses in the first quarter of 2016 went to landing fees and 4.6 percent went to non-aircraft rents and ownership, according to data collected by Airlines for America.

In addition to Airport Revenues, the City also pledged as-Other 'Available MbheysPFC'ReVenu'es'through 2018 equal to the amount of annual debt service on the Series 2008A and Series 2010F Bonds,' or any bonds refunding those bonds', and 'through maturity•bh':the :Se>ies -2011A''Bonds, "or any bonds refunding those bonds/plus any required coverage on those bonds. As described in Section 5.411';' PFC Revenues' are assumed to be applied to pay debt service on the Series'2008A' and Series 2010F Bonds, or any bonds refunding those bonds, from 2019 through-the end of the PrbjectiPri Period. It is assumed that PFC Revenues equal to the amount of annual debt service on the 2016F New Money Bonds will be pledged as Other Available Moneys through the Projection Period. Also, the City has pledged as Other Available Moneys Grant Receipts from FAA Letter of Intent grants,and other. FAA discretionary grants to the.debt, service on the.Series 2011B Bonds, in addition to Airport. Revenues. It is, assumed in this, analysis that Grant Receipts from FAA Letter of Intent grants will be pledged as Other Available Moneys to pay debt service on the 2016E New.Money Bonds through,the Projection. Period. As .shown, the Debt Service,coverage, ratio is projected to,meet the minimum requirement of l.lOx in each year of the. projection period.

5.10 Assumptions Underlying the Financial Projections

The techniques and methodologies used in preparing this financial analysis are consistent with industry practices for similar studies in connection with airport revenue bond sales.' While R&A believes that the approach and assumptions used are reasonable, some assumptions regarding future trends and events presented in this Report, including, but not limited to, the implementation schedule and enplanement projections, may not materialize. Achievement of,the. projections presented in this Report,, therefore, is dependent upon the occurrence of future events, which cannot be assured; and the variations may be material.

PROPOSED FORMS OF OPINIONS OF CO-BOND COUNSEL
[This Page Intentionally Left Blank]
1FORM OF SERIES 2016A CO-BOND COUNSEL OPINION]

December 5, 2016


City of Chicago City Hall Chicago, Illinois
We have examined a record of proceedings relating to the issuance of $27,335,000 aggregate principal amount of Chicago O'Hare International Airport General Airport Senior Lien Revenue Refunding Bonds, Series 2016A (the "Bonds") of the City of Chicago, a municipal corporation and a home rule unit of local government of the State of Illinois (the "City"). The Bonds are limited obligations of the City issued pursuant to the authority of Article VII, Section 6(a) of the Illinois Constitution of 1970 and by virtue of an ordinance adopted by the City Council of the City on September 14, 2016 (the "Bond Ordinance").
The Bonds are authorized by the City for the primary purpose of refunding bonds (the "Prior Bonds") previously issued for the purpose of providing funds to finance the cost of certain capital projects at Chicago O'Hare International Airport (the "Airport").
The Bonds are being issued pursuant to a Master Indenture of Trust Securing Chicago O'Hare International Airport General Airport Revenue Senior Lien Obligations, dated as of September 1, 2012 (the "Indenture"), between the City and U.S. Bank National Association, as Trustee (the "Trustee"), and a Fifty-Second Supplemental Indenture Securing Chicago O'Hare International Airport General Airport Senior Lien Revenue Refunding Bonds, Series 2016A, dated as of December 1, 2016 (the "Fifty-Second Supplemental Indenture"). The Bonds are Senior Lien Obligations authorized under the Indenture and are payable solely from and secured by a pledge of Revenues of the Airport as, and to the extent, provided in the Indenture and the Fifty-Second Supplemental Indenture. Terms used herein that are defined in the Indenture and the Fifty-Second Supplemental Indenture shall have the meanings set forth therein unless otherwise defined herein.
Under the terms of the Indenture, the City has previously issued Senior Lien Obligations that are presently outstanding and the City may hereafter authorize and issue additional Senior Lien Obligations as permitted by the Indenture. Senior Lien Obligations are entitled to the benefit and security of the Indenture, including the pledge of Revenues and other funds maintained for the benefit of the Senior Lien Obligations.
The Bonds are issuable only as fully registered bonds without coupons in the denomination of $5,000 or any integral multiple thereof. The Bonds are dated December 5, 2016 and bear interest from their date payable on January 1, 2017, and semi-annually thereafter on each January 1 and July 1 until paid. The Bonds mature on January 1 in each ofthe following years in the respective principal amounts set opposite such years and the Bonds maturing in each such year bear interest at the respective rates of interest per annum set opposite such principal amounts in the following table:

The Bonds maturing:on or after January 1, :2027 are 'subject to redemption,* at the- option' of the City, on or after January 1, 2026, as a whole or in part at any time, and* if in part, from such maturities as the City shall determine and by lot. for Bonds of the same maturity, at a redemption price equal to the principal amount thereof to be redeemed, plus accrued interest to the date of redemption.
In connection with the issuance of the Bonds we have examined the following: (a) the Constitution ofthe State of Illinois, and such laws as we deemed pertinent to this opinion; (b)a certified copy of the Bond Ordinance, (c) executed counterparts of the Indenture and the Fifty-Second Supplemental Indenture; and (d) such other documents and related matters of law as we have deemed necessary in order to render this opinion.
, Based, upon our. examination of the foregoing, we are of the opinion that:
1. The City is a municipal corporation duly, existing under, the laws of the State of Illinois and is a home rule unit of local government within the meaning, of Section 6(a) of Article VII of the 1970 Illinois Constitution. The City has all requisite power and authority under the Constitution and the laws of the State of Illinois and the Bond Ordinance (i) to enter into the Indenture and the Fifty-Second Supplemental Indenture with the Trustee and to issue the Bonds thereunder, and (ii) to improve, maintain and operate the Airport and to charge and collect rents, fees and other charges for the use and services of the Airport and to perform all of its obligations under the Indenture and the Fifty-Second Supplemental Indenture in those respects.

The Bond Ordinance is in full force and effect and is valid and binding upon the City in accordance with its terms. The Indenture and the Fifty-Second Supplemental Indenture have been duly authorized, executed and delivered by the City, constitute valid and binding obligations of the City and are legally enforceable in accordance with their terms.
The Bonds have been duly authorized and issued, are the legal, valid and binding limited obligations of the City, are entitled to the benefits and security of the Indenture and the Fifty-Second Supplemental Indenture, and are enforceable in accordance with their terms.

The Bonds are payable solely from the Revenues deposited in the 2016A Dedicated Sub-Fund maintained by the Trustee under the Fifty-Second Supplemental Indenture, the Common Debt Service Reserve Sub-Fund on a parity with other Common Reserve Bonds and certain other amounts as provided in the Indenture and the Fifty-Second Supplemental Indenture. The Bonds and the interest thereon are limited obligations of the City and do not constitute an indebtedness of the City within the meaning of any state constitutional or statutory limitation or give rise to a charge against its general credit or taxing powers. Neither the faith and credit nor the taxing power of the State of Illinois, the City or any political subdivision of the State of Illinois is pledged to the payment of the principal of, premium, if any, or interest on the Bonds.
The Indenture and the Fifty-Second Supplemental Indenture create the valid and binding assignments and pledges which they purport to create of the amounts assigned and pledged to the Trustee under the Indenture and the Fifty-Second Supplemental Indenture.
Under existing law, interest on the Bonds is not includible in the gross income of the owners thereof for Federal income tax purposes. If there is continuing compliance with the requirements ofthe Internal Revenue Code of 1986 (the "Code"), we are of the opinion that interest on the Bonds will continue to be excluded from the gross income of the owners thereof for Federal income tax purposes. We express no opinion as to the exclusion from gross income for Federal income tax purposes of interest on any Bond for any period during which such Bond is held by a person who is a "substantial user" of the facilities financed with the proceeds of the Bonds or a "related person" (as defined in Section 147(a) ofthe Code). Furthermore, you are advised that interest on the Bonds constitutes an item of tax preference for purposes of computing individual and corporate alternative minimum taxable income for purposes of the individual and corporate alternative minimum tax. Interest on the Bonds is not exempt from present Illinois income taxes.

The Code contains certain requirements that must be satisfied from and after the date hereof in order to preserve the exemption from Federal income taxes of interest on the Bonds. These requirements relate to the use and investment of the proceeds of the Bonds, the payment of certain amounts to the United States of America, the security and source of payment ofthe Bonds and the use and tax ownership of the property financed

with the proceeds of the Prior Bonds and the Bonds. The City has covenanted in the Indenture to comply with these requirements.
With respect to the exclusion from gross income for Federal income tax purposes of interest on the Bonds, we have relied on the verification report of Robert Thomas, CPA LLC, certified public accountants, regarding the computation of arbitrage yield on the Bonds and of certain investments made with the proceeds of the Bonds.
In rendering the foregoing opinion, we advise you that the enforceability (but mot the validity or binding effect) of the Bonds, the Indenture and the Fifty-Second Supplemental Indenture (i) may be limited by any applicable bankruptcy, insolvency or other laws affecting the rights or remedies of creditors now or hereafter in effect and (ii) is subject to principles of equity in the event that equitable remedies are sought, either in an action at law or in equity.
Respectfully yours, •

The City has all requisite power and authority under the Constitution and the laws of the State of Illinois and the Bond Ordinance (i) to enter into the Indenture and the Fifty-Third Supplemental

The Bond Ordinance is in full force and effect and is valid and binding upon the City in accordance with its terms.

the Bonds does not constitute an item of tax preference for purposes of computing individual or corporate alternative minimum taxable income. You are advised, however, that interest on the Bonds is includible in corporate earnings and profits and therefore must be taken into account when computing - for example,5 corporate .alferhative niinimum taxable income for purposes of the corporate alternative minimum tax. Interest on the Bonds is not exempt from present Illinois income taxes.

We have examined a record of proceedings relating to the issuance of $525,055,000 aggregate principal amount of Chicago O'Hare International Airport General Airport Senior Lien Revenue Refunding Bonds, Series 2016C (the "Bonds") of the City of Chicago, a municipal corporation and a home rule unit of local government of the State of Illinois (the "City").

F-10

The Bond Ordinance is in full force and effect and is valid and binding upon the City in accordance with its terms. The Indenture and the Fifty-Fourth Supplemental Indenture have been duly authorized, executed and delivered by the City, constitute valid and binding obligations of the City and are legally enforceable in accordance with their terms.
The Bonds have been duly authorized and issued, are the legal, valid and binding limited obligations of the City, are entitled to the benefits and security of the Indenture and the Fifty-Fourth Supplemental Indenture, and are enforceable in accordance with their terms.
The Bonds are payable solely from the Revenues deposited in the 2016C Dedicated Sub-Fund maintained by the Trustee under the Fifty-Fourth Supplemental Indenture, Pledged Other Available Moneys deposited in the 2016C PFC Revenue Deposit Account maintained by the Trustee under the Fifty-Fourth Supplemental Indenture and certain other amounts as provided in the Indenture and the Fifty-Fourth Supplemental Indenture. The Bonds and the interest thereon are limited obligations of the City and do not constitute an indebtedness of the City within the meaning of any state constitutional or statutory limitation or give rise to a charge against its general credit or taxing powers. Neither the faith and credit nor the taxing power of the State of Illinois, the City or any political subdivision of the State of Illinois is pledged to the payment of the principal of, premium, if any, or interest on the Bonds.
The Indenture and the Fifty-Fourth Supplemental Indenture create the valid and binding assignments and pledges which they purport to create of the amounts assigned and pledged to the Trustee under the Indenture and the Fifty-Fourth Supplemental Indenture.
Under existing law, interest on the Bonds is not includible in the gross income of the owners thereof for Federal income tax purposes. If there is continuing compliance with the requirements of the Internal Revenue Code of 1986 (the "Code"), we are of the opinion that interest on the Bonds will continue to be excluded from the gross income of the owners thereof for Federal income tax purposes. In addition, interest on the Bonds does not constitute an item of tax preference for purposes of computing individual or corporate alternative minimum taxable income. You are advised, however, that interest on the Bonds is includible in corporate earnings and profits and therefore must be taken into account when computing, for example, corporate alternative minimum taxable income for purposes of the corporate alternative minimum tax. Interest on the Bonds is not exempt from present Illinois income taxes.

The Code contains certain requirements that must be satisfied from and after the date hereof in order to preserve the exemption from Federal income taxes of interest on the Bonds. These requirements relate to the use and investment of the proceeds of the Bonds, the payment of certain amounts to the United States of America, the security and source of payment of the Bonds and the use and tax ownership of the property financed with the proceeds of the Prior Bonds and the Bonds. The City has covenanted in the Indenture to comply with these requirements.

With respect to the exclusion from gross income for Federal income tax purposes of interest on the Bonds, we have relied on the verification report of Robert Thomas, CPA LLC, certified public accountants, regarding the computation of arbitrage yield on the Bonds and of certain investments made with the proceeds of the Bonds.
In rendering the foregoing opinion, we advise you that the enforceability (but not the validity or binding effect) of the Bonds, the Indenture and-the Fifty-Fourth Supplemental Indenture (i). may be limited by any applicable bankruptcy, insolvency or-other;laws affecting the rights or remedies of creditors now or hereafter in effect! and (ii) is subject to iprinciples of equity in the event that equitable remedies are sought, either in an action at law or in equity.;

Appendix C
DESCRIPTION OF BOOK-ENTRY ONLY SYSTEM

General. The following information has been furnished by DTC for use in this Official Statement and neither the City nor any Underwriter takes any responsibility for its accuracy or completeness. The DTC Omnibus Proxy record date, as such term is used under this subcaption, is not, and has no relation to, the "Record Date" as defined in Appendix A — "Glossary of Terms" and used in this Official Statement.

DTC will act as securities depository for the 2016 Senior Lien Bonds. The 2016 Senior Lien Bonds will be issued as fully-registered securities registered in the name of Cede & Co. (DTC's partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered 2016 Senior Lien Bond certificate will be issued for each maturity of each Series of the 2016 Senior Lien Bonds, in the aggregate principal amount of such maturity, and will be deposited with DTC.

DTC, the world's largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency"'registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC's participants ("Direct Participants") deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants' accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation ("DTCC"). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly ("Indirect Participants"). DTC has a Standard & Poor's rating of AA+. The DTC Rules applicable to its Participants are on file with the Securities and Exchange Commission. More information about DTC can be found at www.dtcc.com .

Purchases of 2016 Senior Lien Bonds under the DTC system must be made by or through Direct Participants, which will receive a credit for the 2016 Senior Lien Bonds on DTC's records. The ownership interest of each actual purchaser of each 2016 Senior Lien Bond ("Beneficial Owner") is in turn lo be recorded on the Direct and Indirect Participants' records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details ofthe transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the 2016 Senior Lien Bonds are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in 2016 Senior Lien Bonds, except in the event that use of the book entry system for the 2016 SeniorLien Bonds is discontinued.

G-l

To facilitate subsequent transfers, all 2016 Senior Lien Bonds deposited by Direct Participants with DTC are registered in the name of DTC's partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of 2016 Senior Lien Bonds with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in'beneficial ownership. DTC has no knowledge of the actual Beneficial Owner's of the 2016 Senior Lien Bonds; DTC's records reflect drily the identity of the Direct Participants to whose accounts such 2016 Senior Lien -Bonds are credited, which may or-may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants' and Indirect Participants to Beneficial Owners will-be- governed by arrangements' among' theriv subject to any statutory ;or regulatory requirements as may be in effect from time'to-time: Beneficial Owners of the 2016 Senior Lien Bonds may wish to take certain steps to augment the transmission to;'them of notices of significant events with respect to the 2016 Senior Lien Bonds, such as redemptions, tenders, defaults, and proposed amendments to the Senior Lien Bond documents; For example, Beneficial Owners of the 2016 Senior Lien Bonds may wish to- ascertain that the nominee holding the'2016 Senior- Lien'Bonds for their benefit has agreed to obtain and transmit notices to-Beneficial Owners. In the alternative, Beneficial Owners may wish to provide their names and addresses'to'the Trustee and request that copies of notices be provided directly to them.

Redemption notices' shall be sent to DTC. If fewer than all of the 2016 Senior Lien Bonds ofia maturity are ^beirig redeemed;- DTC's practice is to determine by lot the amount of the interest of each Direct Participant in the 2016 Senior Lien Bonds to be redeemed.

Neither DTC nor Cede & Cb; (nor any other DTC nominee) will consent or vote with respect to the 2016 Senior Lien Bonds unless authorized by a Direct Participant in accordance with DTC's MMI Procedures: Under its usual procedures', DTC mails an Omnibus Proxy to the City as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those Direct'Participants to whose accounts the 2016 Senior Lien Bonds are credited on the record date (identified in a listing attached to the Omnibus Proxy). -
Redemption proceeds, distributions, and interest payments on the 2016 Senior Lien Bonds will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC's practice is to credit Direct Participants' accounts upon'DTC's receipt of funds and corresponding detail information from the City or the Trustee;'on the payable date in accordance with their respective holdings shown on DTC's records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of such Participant and not of DTC, the Trustee or the City, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds and interest to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility ofthe City or the Trustee, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants.

DTC may discontinue providing its services as securities depository with respect to the 2016 Senior Lien Bonds at any time by giving reasonable notice to the City or the Trustee. Under such


G-2

circumstances, in the event that a successor securities depository is not obtained, certificates for the 2016 Senior Lien Bonds are required to be printed and delivered.

The City may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, certificates for the 2016 Senior Lien Bonds will be printed and delivered to DTC.

For every transfer and exchange of the 2016 Senior Lien Bonds, the Trustee and DTC and the Participants may charge the beneficial owner a sum sufficient to cover any tax, fee or other charge that may be imposed in relation thereto.

The City and the Trustee shall have no responsibility or obligation with respect to (i) the accuracy of the records of DTC, Cede & Co. or any Participant with respect to any ownership interest in the 2016 Senior Lien Bonds, (ii) the delivery to any Participant or any other person, other than an owner, of any notice with respect to the 2016 Senior Lien Bonds, including any notice of redemption, or (iii) the payment to any Participant or any other person, other than an owner, of any amount with respect to principal of or interest on the 2016 Senior Lien Bonds.

The 2016 Senior Lien Bonds will be issuable as fully registered bonds in denominations that are integral multiples of $5,000. Exchanges and transfers will be made without charge to the Registered Owners, except that in each case the Trustee may require the payment by the Registered Owner requesting exchange or transfer of any tax or governmental charge required to be paid with respect thereto.

Principal of and interest on the 2016 Senior Lien Bonds will be payable upon presentation and surrender when due at the principal corporate trust office of the Trustee. Interest on the 2016 Senior Lien Bonds will be payable by check mailed to the persons in whose names they are registered at the close of business on the Record Date next preceding each Interest Payment Date. The Record Date for the 2016 Senior Lien Bonds will be the June 15 and December 15 prior to each July 1 and January 1, respectively. At the request of any Registered Owner of not less than $1,000,000 principal amount of the 2016 Senior Lien Bonds of a Series, all payments to such Registered Owner with respect to such Series of 2016 Senior Lien Bonds shall be made by wire transfer to any address in the continental United States on the applicable Payment Date, if such Registered Owner provides the Trustee with written notice of such wire transfer address prior to the applicable Record Date (which notice may provide that it will remain in effect with respect to subsequent Interest Payment Dates unless and until changed or revoked by subsequent notice).
