Second Lien Wastewater Transmission Revenue Bonds, Series 2015 (Taxable)

DETERMINATION CERTIFICATE

An ordinance adopted by the City Council of the City of Chicago (the "City") on September 24, 2015 (the "2015 Bond Ordinance"), authorized the issuance of not to exceed $125,000,000 aggregate principal amount of Wastewater Transmission Revenue Bonds, Series 2015 (Taxable) (the "Series 2015 Bonds") of the City. The 2015 Bond Ordinance authorized the Chief Financial Officer of the City or, if the Chief Financial Officer so determines and designates, the City Comptroller of the City (the "Authorized Officer") to (a) determine the amount and an identification of the Short Term Obligations to be refunded and the date upon which the refunding is to be effected, (b) determine the identification of the interest-rate swaps that related to the Outstanding Series 2008C Second Lien Bonds and are being terminated and the cost of terminating each such swap, (c) various terms and provisions of the Series 2015 Bonds within limitations established by the 2015 Bond Ordinance, (d) execute on behalf of the City a Bond Purchase Agreement for the sale by the City of the Series 2015 Bonds to the Initial Purchasers selected by the Authorized Officer pursuant to a negotiated sale on such terms as the Authorized Officer may deem to be in the best interests of the City, as provided in the 2015 Bond Ordinance, (e) approve the form and execute and deliver on behalf of the City a 2015 Bonds Indenture (as defined in the 2015 Bond Ordinance) pursuant to which the Series 2015 Bonds will be issued and a Continuing Disclosure Undertaking with respect to the Series 2015 Bonds, and (f) take such other actions as are necessary to cause the Series 2015 Bonds to be issued and delivered. The 2015 Bond Ordinance provides for the Authorized Officer to execute a Determination Certificate setting forth the various determinations made by her with respect to the Series 2015 Bonds. The Authorized Officer is to file the Determination Certificate in the Office of the City Clerk of the City, addressed to the City Council.

I am the duly qualified and serving Chief Financial Officer of the City and an Authorized Officer within the meaning of the 2015 Bond Ordinance. I make and file this Determination Certificate in accordance with the 2015 Bond Ordinance. All terms used in this Determination Certificate and defined in the 2015 Bond Ordinance or the 2015 Bonds Indenture shall have the meanings ascribed to them in the 2015 Bond Ordinance or the 2015 Bonds Indenture.

I have determined as follows with respect to the Series 2015 Bonds authorized by the 2015 Bond Ordinance, in each case within the authority granted to me by the 2015 Bond Ordinance:

Findings. On behalf of the City, I find and determine, as follows:

The City has received an offer from Ramirez & Co., Inc., Mesirow Financial, Inc., The Williams Capital Group, L.P., Estrada Hinojosa & Company, Inc., Janney Montgomery Scott LLC, Jefferies LLC, Rice Financial Products Company and Academy Securities, Inc. (collectively, the "Underwriters") to purchase $87,080,000 principal amount of Second Lien Wastewater Transmission Revenue Bonds, Series 2015 (Taxable) of the City (the "Series 2015 Bonds"), pursuant to a Bond Purchase Agreement, dated October 14, 2015, between the City and the Underwriters, a copy of which is attached as Exhibit A to this Determination Certificate (the "Bond Purchase Agreement"). The Bond Purchase Agreement is in substantially the form previously used for similar financings of the City and is consistent with the 2015 Bond Ordinance. The purchase price of the Bonds specified in the Bond Purchase Agreement is $86,659,592.56 (reflecting the aggregate par principal amount less an underwriters' discount of $420,407.44), which results in a purchase price that is not less than 85 percent of the original principal amount of the Series 2015 Bonds, plus any accrued interest on the Series 2015 Bonds from their date to the date of their delivery and less any original issue discount on the Series 2015 Bonds, which is within the limit provided in the 2015 Bond Ordinance. Selling the Series 2015 Bonds to the Underwriters upon the terms provided in the Bond Purchase Agreement is in the best interests of the City.
The Chairman of the Committee on Finance of the City Council has concurred in the acceptance by the City of the Bond Purchase Agreement, as being within the authority granted by the 2015 Bond Ordinance.
The terms of the Series 2015 Bonds as specified in this Determination Certificate and the 2015 Bonds Indenture provide funds to (i) refund certain Line of Credit Notes incurred for the purpose of converting the City's outstanding Second Lien Variable Rate Wastewater Transmission Revenue Refunding Bonds, Series 2008C (the "Series 2008C Bonds") to bear interest at fixed rates including the termination of certain interest rate swaps related to such Series 200C Bonds (ii) make a deposit in the Debt Service Reserve Account for the Bonds, (iii) pay a portion of the cost of converting the Series 2008C Bonds, including the making of a deposit to the Debt Service Reserve Account for the Series 2008C Bonds, (iv) fund capitalized interest on the Bonds, and (v) pay Costs of Issuance of the Bonds, all as provided in the 2015 Bond Ordinance. Any changes made by this Determination Certificate to the terms of the Series 2015 Bonds thus will result in the Series 2015 Bonds having substantially the same terms as provided in the 2015 Bond Ordinance.
The interest rates or yields for the Series 2015 Bonds set forth in this Determination Certificate are in my judgment the best rates at which the Series 2015 Bonds can be sold in the market under current circumstances. The interest rates for the Series 2015 Bonds do not exceed 15% per year, the maximum interest rate set forth in the 2015 Bond Ordinance.
Prior to the issuance of the Series 2015 Bonds, the City enacted increases in the rates of the Sewer System pursuant to an ordinance adopted by the City Council on November 2, 2011 which rate increases went into effect on January 1, 2012, January 1, 2013, January 1, 2014 and January 1, 2015. To the extent permitted by the requirements of the Series 1998 Bond Ordinance, the Series 2001 Indenture, the Series 2004B Indenture, the Series 2006 Indenture, the Series 2008A Indenture and the Series 2012 Indenture, I have adjusted Net Revenues Available for Bonds for 2015 and 2016 to reflect such rate increases.|1010|
The Series 2015 Bonds will be issued pursuant to a Trust. Indenture, dated as of October 1, 2015 (the "2015 Bonds Indenture") from the City to Amalgamated Bank of Chicago, as trustee (the "Trustee"), which is attached as Exhibit B to this Determination Certificate. The 2015 Bonds Indenture is in substantially the form previously used for similar financings of the City. The 2015 Bonds Indenture contains only such changes and revisions as are consistent with the purposes and intent of the 2015 Bond Ordinance, including such changes and revisions as are necessary to reflect the terms and provisions of the Series 2015 Bonds, and I approve such changes. The 2015 Bonds Indenture includes such covenants with respect to the imposition of Sewer System rates, the issuance of Second Lien Parity Bonds, the application of funds in the Sewer Revenue Fund and the applicable Accounts and other matters relating to the Series 2015 Bonds and the security for them, including the lien status of the Series 2015 Bonds, as I deem necessary in connection with the sale of the Series 2015 Bonds. Such covenants are not inconsistent with the terms of the 2015 Bond Ordinance.
The issuance of the Series 2015 Bonds with the terms set forth in this Determination Certificate will comply with the requirements of the indentures for the Outstanding Second Lien Bonds for the issuance of additional Second Lien Parity Bonds:

all funds required to be transferred to the principal and interest accounts and the debt service reserve accounts in the revenue funds established for the Outstanding Second Lien Bonds have been transferred in full up to the date of this Determination Certificate; and
as shown on Exhibit C, Net Revenues Available for Bonds for the last completed Fiscal Year ended December 31, 2014 (as shown by the audit of an independent certified public accountant), equal at least 100 percent of the sum of the Aggregate Senior Lien Debt Service and the Aggregate Second Lien Debt Service in each Fiscal Year following the issuance of the Series 2015 Bonds, computed on a pro forma basis assuming the issuance of the Series 2015 Bonds and the application of the proceeds of the Series 2015 Bonds as provided in the 2015 Bonds Indenture and this Determination Certification.
The amount that will be needed by the City to pay the costs constituting Financing Purposes, taking into account moneys that will be available from other sources (including investment earnings on proceeds of sale of the Series 2015 Bonds during the period before they are applied to pay such costs) to pay such costs, does not exceed the amount authorized by the 2015 Bond Ordinance to be issued for Financing Purposes.

(i) This Determination Certificate is consistent with the terms of sale of the Series
2015 Bonds in the Bond Purchase Agreement.

The Ordinance and the Indenture. The Bonds will be issued and secured under and have such terms and conditions as are provided in the ordinance adopted by the City Council of the City on September 24, 2015 (the "Ordinance"), and a Trust Indenture dated as of October 1, 2015 (the "Indenture"), from the City to Amalgamated Bank of Chicago, Chicago, Illinois, as trustee (the "Trustee").

It shall be a condition to the obligation of the City to sell and deliver the Bonds to the Underwriters, and to the obligation of the Underwriters to purchase and to pay for the Bonds, that the entire principal amount of the Bonds to be sold pursuant to Section 1 hereof shall be sold and delivered to, and purchased and paid for by the Underwriters at the Closing (hereinafter defined). Subsequent to such initial public offering, the Underwriters reserve the right to change such initial public offering prices as the Underwriters deem necessary or desirable, in their sole discretion, in connection with the marketing of the Bonds, and may offer and sell the Bonds to certain dealers, unit investment trusts and money market funds, certain of which may be sponsored or managed by one or more of the Underwriters at prices lower than the public offering prices or yields greater than the yields set forth therein.

For purposes of this Agreement, the term "end of the underwriting period" shall be the later ofthe date of Closing or the date on which an Underwriter no longer retains an unsold balance ofthe Bonds for sale to the public.

The Underwriters agree that the date on which the end of the underwriting period shall occur shall be the date of the Closing unless the Underwriters otherwise notify the City in writing prior to 25 days after the Closing that, to the best of their knowledge, the Underwriters retain for sale to the public an unsold balance of the Bonds, in which case the end of the underwriting period shall be extended for additional periods of 30 days each upon receipt of an additional written notification from the Underwriters that, to the best of their knowledge, there exists an unsold balance of the Bonds.

At or prior to the Closing, the Representative shall file, or cause to be filed, the Official Statement with the MSRB through its Electronic Municipal Market Access ("EMMA") system for municipal securities disclosure or through any other electronic format or system then prescribed by the MSRB or the SEC.

FORM OF SUPPLEMENTAL OPINION OF CO-BOND COUNSEL

[Date of Closing]

October 19, 2015


City of Chicago The Underwriters Listed
City Hall on Annex I
121 North LaSalle Street Chicago, Illinois 60602
Amalgamated Bank of Chicago, as trustee under the Trust Indenture defined below 30 North LaSalle Street 38th Floor
Chicago, Illinois 60603


We have acted as co-bond counsel in connection with the issuance and delivery by the City of Chicago (the "City") of the City's $87,080,000 Second Lien Wastewater Transmission Revenue Bonds, Series 2015 (Taxable) (the "Bonds"). The Bonds are authorized by an Ordinance adopted by the City Council of the City on September 24, 2015 (the "Bond Ordinance") and are being issued today under and pursuant to the Bond Ordinance, a Determination Certificate of the Chief Financial Officer of the City pursuant to the Bond Ordinance establishing certain terms of the Bonds and filed with the City Clerk pursuant to the Bond Ordinance (the "Determination Certificate"), and a Trust Indenture, dated as of October 1, 2015 (the "Trust Indenture"), from the City to Amalgamated Bank of Chicago, as trustee (the "Trustee"), providing for the issuance of the Bonds. We rendered our separate approving opinion today as co-bond counsel as to the validity of the Bonds. Capitalized terms used but not defined in this letter have the meanings ascribed to them in our separate approving opinion as co-bond counsel.
The following opinion is based upon the same examination of the record of proceedings and accompanying certificates, and is subject to the same limitations, as described in our separate approving opinion as co-bond counsel described above. In addition to the items described in our separate approving opinion as co-bond counsel, the record of proceedings also includes executed copies of the Bond Purchase Agreement, dated October 14, 2015 (the "Bond Purchase Agreement"), between the City and the underwriters listed on Exhibit A (the "Underwriters"), and of the Official Statement, dated October 14, 2015, of the City relating to

i
I
the Bonds (the "Official Statement"). We are furnishing this opinion pursuant to Section 9(d)(ii) of the Bond Purchase Agreement.
Based upon our examination as described in our separate opinion as co-bond counsel, we are further of the opinion as follows:
The Bonds are exempt from registration under the Securities Act of 1933, as amended, and the Trust Indenture is exempt from qualification under the Trust Indenture Act of 1939, as amended. It is not necessary, in connection with the initial public offering and sale of the Bonds in the manner contemplated in the Bond Purchase Agreement, to register any securities under the Securities Act or to qualify the Bond Ordinance or the Trust Indenture under the Trust Indenture Act.
We have reviewed the statements in the Official Statement on its covers, under the captions "Official Statement Summary," "Introduction," "The Bonds" (other than information under the subcaption "Book-Entry Only System"), and "Security for THE Bonds," and in Appendices B and C and, insofar as those statements purport to summarize certain provisions of the Bonds, the Bond Ordinance, the Determination Certificate and the Trust Indenture, such statements present a fair and accurate summary of those provisions. The statements in the Official Statement in the first paragraph on its cover, under the caption "Official Statement Summary — Tax Matters," under the caption "Certain Tax Considerations," and in Appendix D, present a fair and accurate summary of the matters relating to the taxability of interest on the Bonds discussed in such portions of the Official Statement.
The execution and delivery on behalf of the City of the Bond Purchase Agreement has been duly authorized by the City. The Bond Purchase Agreement is a binding contractual obligation of the City in accordance with its terms if it is a valid and binding obligation of the Underwriters (as to which we express no opinion). The Continuing Disclosure Undertaking has been duly authorized, executed and delivered by the City and is a binding contractual obligation of the City in accordance with its terms.
Except as stated in paragraph 2 of this letter, we have not undertaken to determine independently the accuracy or completeness of the Official Statement. However, we state that during our participation in the authorization and issuance of the Bonds as co-bond counsel (which included participation in conferences with the City and the underwriters and their respective counsel concerning the Official Statement), nothing has come to our attention which has caused us to believe that the Official Statement (except for statements in the Official Statement Summary under the captions "—Sewer System," "—Investment Considerations" and "—Retirement Funds," statements under the captions "INTRODUCTION—Sewer System," "The Bonds—Book-Entry Only System," "Outstanding Debt and Annual Debt Service," "The Wastewater Transmission System," "Financial Operations," "Investment Considerations," "Litigation," "Financial Advisor and Independent Registered Municipal Advisor," and "Secondary Market Disclosure—Compliance by the City With Respect to Certain Bond Disclosure Requirements," and in Appendix A - "City of Chicago,

Illinois Sewer Fund Basic Financial Statements" and Appendix E - "Retirement Funds" and the financial and statistical data in the Official Statement, as to which we express no view), as of its date or as of the date of this letter, contained or contains an untrue statement of a material fact or omitted or omits a material fact necessary to make the statements in it, in light of the circumstances under which they were made, not misleading.
The enforceability of provisions of the Bond Purchase Agreement and the Continuing Disclosure Undertaking may be subject to bankruptcy, insolvency, reorganization, moratorium and other similar laws affecting creditors' rights. Enforcement of provisions ofthe Bond Purchase Agreement or the Continuing Disclosure Undertaking by an equitable or similar remedy is subject to general principles of law or equity governing such a remedy, including the exercise of judicial discretion whether to grant any particular form of relief. The enforceability of the indemnification provisions of the Bond Purchase Agreement may be limited by federal or state securities laws.
This opinion is based upon facts known or certified to us and laws in effect on its date and speaks as of that date. The opinions stated in this letter are expressions of professional judgment based upon such facts and law and are not a guaranty of a result. We have not undertaken any obligation to revise or supplement this opinion to reflect any facts or circumstances that may come to our attention after the date of this opinion or any changes in law that may occur after that date.
The opinions rendered and assurances given in this letter are solely for the benefit of the persons to whom this letter is addressed in connection with the issuance and delivery of the Bonds and may not be relied upon by other persons or for any other purpose without our express prior written consent.

FORM OF OPINION OF CORPORATION COUNSEL

[Date of Closing]


Amalgamated Bank of Chicago, as Trustee One West Monroe Street Chicago, Illinois 60603

Samuel A. Ramirez & Company, Inc. 200 North LaSalle Street, Suite 1900 Chicago, IL 60601
on behalf of the Underwriters named in the
Bond Purchase Agreement (as defined herein)

Ladies and Gentlemen:

I am the Corporation Counsel of the City of Chicago (the "City"). In connection with the issuance by the City of S87,080,000 aggregate principal amount of Second Lien Wastewater Transmission Revenue Bonds, Series 2015 (Taxable) (the "Bonds"), I have caused to be examined a certified copy of the record of proceedings of the City Council of the City (the "City Councir) pertaining to the adoption by the City Council on July 29, 2015, of an ordinance pursuant to which the Bonds are being issued (the "Ordinance"). Unless otherwise defined herein, capitalized terms defined in the Bond Purchase Agreement are used with the same meaning herein.

In addition to the Ordinance, I have caused to be examined final and/or executed copies ofthe following documents:
the Official Statement;
that certain Trust Indenture dated as of October 1, 2015, from the City to Amalgamated Bank of Chicago, as trustee (the "Trustee") in connection with the Bonds (the "Indenture");
that certain Bond Purchase Agreement dated October 14, 2015 (the "Bond Purchase Agreement"), between the City and the Underwriters referred to therein (the "Underwriters");
the Undertaking;
the Determination Certificate; and


C-l

(vi) such other documents and records as were deemed necessary to enable me to render this opinion.

Based on the foregoing, I am of the opinion that:
The City is a municipal corporation and home rule unit of local government, organized and existing under the laws of the State of Illinois.
The City has duly authorized, approved and executed the Official Statement.
The City Council has (a) duly passed the Ordinance, which has not been amended, modified, supplemented or repealed and is in full force and effect; and (b) duly authorized and approved the execution and delivery of the Bonds, the Official Statement, the Bond Purchase Agreement, the Indenture, and the Undertaking. Assuming due execution and delivery by the other parties thereto, as applicable, the Bond Purchase Agreement, the Indenture, the Determination Certificate, and the Undertaking (collectively, the "City Documents") constitute valid and legal obligations of the City enforceable in accordance with their respective terms, except as enforcement may be limited by (i) applicable bankruptcy, insolvency or other laws affecting the rights or remedies of creditors generally of entities similar to the City, and (ii) the discretion of the courts in granting equitable or similar remedies.
The City has full legal right, power and authority to: (a) enter into and to execute the City Documents; and (b) issue, sell and deliver the Bonds to the Underwriters pursuant to the Ordinance and the Indenture. To my knowledge, the passage of the Ordinance and compliance with its provisions do not violate any applicable law or administrative regulation of the State of Illinois or of any department, division, agency or instrumentality thereof or of the United States of America, or any applicable judgment or decree to which the City is subject and do not conflict in a material manner with or constitute a material breach of or a material default under any agreement or other instrument to which the City is a party or is otherwise subject.
To my knowledge, the City has obtained all approvals, consents and orders (except, if any, with respect to state "blue sky" laws) of any governmental authority, board, agency or commission having jurisdiction which would constitute a condition precedent to the performance by the City of its obligations under the City Documents which the City could reasonably obtain as of the date hereof.
No litigation is pending or, to my knowledge, threatened, seeking to restrain or enjoin the issuance or delivery of the Bonds, or contesting (a) the validity or enforceability of the City Documents, (b) the completeness or accuracy of the Official Statement or (c) the power of the City or its authority with respect to the City Documents.
Nothing has come to my attention which would lead me to believe that the Official Statement contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which


C-2

they were made, not misleading; provided, however, that I express no opinion or belief regarding information under the captions "THE BONDS — Book-Entry Only System,"' "CERTAIN TAX CONSIDERATIONS" and "UNDERWRITING" and in Appendix D -PROPOSED FORM OF OPINIONS OF CO-BOND COUNSEL information sourced in Appendix E — RETIREMENT FUNDS to sources other than the City or departments thereof, any information in or omitted from the Official Statement relating to DTC, any information furnished by the Underwriters for use in the Official Statement, the financial statements in Appendix A - CITY OF CHICAGO, ILLINOIS SEWER FUND BASIC FINANCIAL STATEMENTS AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2014 AND 2013, STATISTICAL DATA, AND INDEPENDENT AUDITORS' REPORT and all other financial and statistical data contained in the Official Statement, including the Appendices thereto.

No opinion is expressed as to any "blue sky" or other securities laws or as to the laws regarding taxation of any state, or the United States, or any disclosure or compliance related thereto.

The statements contained herein are made in an official capacity and not personally and no personal responsibility shall derive from them. Further, the only opinions that are expressed are the opinions specifically set forth herein, and no opinion is implied or should be inferred as to any other matter or transaction.

No one other than you shall be entitled to rely on this opinion.



Very truly yours,


Stephen R. Patton Corporation Counsel

FORM OF LETTER OF SPECIAL DISCLOSURE COUNSEL [TO BE DATED CLOSING DATE]

City of Chicago
121 North LaSalle Street
Chicago, Illinois 60602

Re: $87,080,000 City of Chicago
Second Lien Wastewater Transmission Revenue Bonds, Series 2015 (Taxable) (the "Bonds")
Ladies and Gentlemen:
We have acted as special disclosure counsel to you, the City of Chicago (the "City"), solely in connection with the information contained in Appendix E — "Retirement Funds" (the "Pension Section") of the Preliminary Official Statement dated September-25, 2015, as supplemented by Supplement No. 1 dated October 7, 2015 to the Preliminary Official Statement dated September 25, 2015 (collectively, the "Preliminary Official Statement") and the Official Statement dated October 14, 2015 (the "Official Statement"), each relating to the Bonds issued by the City on this date.

In accordance with our understanding with the City, we have reviewed the Pension Section, certificates of officers of the City and other appropriate persons, and such other records, reports, opinions and documents, and we have made such investigations of law, as we have deemed appropriate as a basis for the conclusion hereinafter expressed. As to facts material to the views expressed herein, we have, with your consent, relied upon oral or written statements or representations of officers or other representatives or agents of or consultants to the City and of or to the Municipal Employees' Annuity and Benefit Fund of Chicago, the Policemen's Annuity and Benefit Fund of Chicago, the Firemen's Annuity and Benefit Fund of Chicago, and the Laborers' and Retirement Board Employees' Annuity and Benefit Fund of Chicago (collectively, the "Retirement Funds "), including the representations and warranties of the City in the Bond Purchase Agreement dated October 14, 2015, with respect to the Bonds, between the City and Samuel A. Ramirez & Company, Inc., on behalf of itself and the other underwriters named therein (collectively, the "Underwriters"). We have not independently verified such matters. Capitalized terms not otherwise defined herein shall have the meanings ascribed thereto in the Official Statement.

In arriving at the conclusion hereinafter expressed, we are not expressing any opinion or view on, and with your permission are assuming and relying on, the validity, accuracy and sufficiency of the records, reports, documents, certificates and opinions referred to above (including the accuracy of all factual matters represented and legal conclusions contained therein, including, without limitation, any representations and legal conclusions regarding the due authorization, issuance, delivery, validity and enforceability of the Bonds, the tax treatment

D-1

of interest on the Bonds for federal income tax purposes, and the application of Bond proceeds in accordance with the authorization therefor). We have assumed that all records, reports, documents, certificates and opinions that we have reviewed, and the signatures thereto, are genuine.

We are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of any of the statements contained in the Pension Section and make no representation that we have independently verified the accuracy, completeness or fairness of any such statements. In our capacity as special disclosure counsel to the City, to assist you in discharging your responsibility with respect to the Pension Section, we participated in conferences and correspondence with representatives of the City, the City's attorneys, Co-Disclosure Counsel to the City, the Underwriters, counsel to the Underwriters, and other persons involved in the preparation of information for the Pension Section, during which the contents of the Pension Section and related matters were discussed and revised. The purpose of our professional engagement was not to establish or confirm factual matters set forth in the Pension Section, and we have not undertaken any obligation to verify independently any of the factual matters set forth therein. Moreover, many of the determinations required to be made in the preparation of the Pension Section involve matters of a non-legal nature. Based on our participation in the above-mentioned conferences and correspondence, and in reliance thereon and on our limited review of the records, reports, documents, certificates, statements, representations, warranties, opinions and matters mentioned above, without independent verification, we advise you as a matter of fact and not opinion that, during our engagement as special disclosure counsel to the City in connection with the Pension Section, no facts came to the attention of the attorneys in our firm rendering legal services in connection with such limited role which caused us to believe that the Pension Section (apart from the financial statements or other financial, operating, numerical, accounting or statistical data or forecasts, estimates, projections, assumptions or expressions of opinion, or matters of litigation contained or incorporated therein, as to which we do not express any conclusion or belief) contained as of its date or contains as of the date hereof any untrue statement of a material fact or omitted or omits to state a material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. No responsibility is undertaken or statement rendered herein with respect to any other portions ofthe Preliminary Official Statement or the Official Statement or any other disclosure document, materials or activity, or as to any information from another document or source referred to by or incorporated by reference in the Preliminary Official Statement or the Official Statement.

By acceptance of this letter you recognize and acknowledge that: (i) the preceding paragraph is not a legal opinion but is rather in the nature of negative observations based on certain limited activities performed by specific lawyers in our firm during our engagement to the City as special disclosure counsel in connection with the Pension Section; (ii) the scope of those activities performed by us for purposes of delivering this letter was inherently limited and does not purport to encompass all activities necessary for compliance with applicable securities laws; and (iii) those activities performed by us rely on third party representations, warranties, certifications, statements and opinions, including and primarily, representations, warranties and certifications made by the City, and are otherwise subject to the conditions set forth herein.


D-2

We express herein no opinion or belief herein with respect to the validity of the Bonds or the taxation thereof or of the interest thereon, and our expression of belief with respect to the Pension Section assumes the validity of the Bonds and the tax treatment of the interest payable thereon for federal income tax purposes, all as set forth in the opinions of Co-Bond Counsel.

This letter is furnished by us in our limited capacity as special disclosure counsel to the City in connection with the Pension Section. This letter may not be used, quoted, relied upon or otherwise referred to for any other purpose or by any other person (including any person purchasing any of the Bonds from the Underwriters) without our prior written consent, except that such letter may be referenced in the Preliminary Official Statement, the Official Statement and the Bond Purchase Agreement with respect to the Bonds and included in the transcript of proceedings for the Bonds. This letter is given as of the date hereof and we assume no obligation to revise or supplement this letter to reflect any facts or circumstances that may hereafter come to our attention.


Respectfully submitted,

RECITALS

The City is a duly constituted and existing municipality within the meaning of Section 1 of Article VII of the 1970 Constitution of the State of Illinois (the "Constitution"), and is a "home rule unit" under Section 6(a) of Article VII ofthe Constitution.
The City has constructed and is maintaining and operating the Sewer System (as defined below) to meet the needs of the City's inhabitants and other users of the Sewer System. The Sewer System is operated under the supervision and control of the Department of Water Management ofthe City.
Pursuant to such authority, the City has previously issued and may in the future issue its Senior Lien Bonds (as defined below) for any lawful purpose of the Sewer System, including refunding Outstanding Senior Lien Bonds (as defined below) or obligations payable from revenues ofthe Sewer System on a basis subordinate to the Senior Lien Bonds (including Second Lien Bonds (as defined below) and Subordinate Lien Obligations (as defined below)) or for paying costs of issuance. The City has previously issued its Outstanding Series 1998 Senior Lien Bonds (as defined below, the "Outstanding Senior Lien Bonds").
Pursuant to such authority, the City has previously issued and may in the future issue its Second Lien Bonds (as defined below) for any lawful purpose of the Sewer System, including refunding Outstanding Senior Lien Bonds and Outstanding Second Lien Bonds (as defined below) or obligations payable from revenues of the Sewer System on a basis subordinate to the Second Lien Bonds (including Subordinate Lien Obligations) or for paying costs of issuance.

Pursuant to an ordinance duly adopted by the City Council on September 24, 2015 (the "Series 2015 Bond Ordinance"), the City has determined to authorize the issuance of its Second Lien Wastewater Transmission Revenue Bonds, Series 2015 (Taxable) (the "2015 Second Lien Bonds").

All amounLs in the Bond Debt Service Reserve Account and each Senior Lien Rebate Account must be invested in Permitted Investments that are held separate and distinct from those of any other Funds or Account. Investments shall be scheduled , to mature before needed for the respective purposes of each of such accounts. All investment earnings on any such Accounts so invested must be credited lo the Sewer Revenue Fund and shall be considered Gross Revenues, except that earnings on the investment of amounts on deposit in the Senior Lien Rebate Accounts shall not be considered Gross Revenues and shall be retained in the respective Senior Lien Rebate Accounts except to the extent no longer required for rebate purposes. See "SECURITY FOR THE BONDS - Flow of Funds," and "-Cash and Investments" in the Official Statement.
Authority for Issuance The Bonds have been authorized and arc being issued pursuant lo the home rule powers of the City
under the Illinois Constitution of 1970 and an ordinance adopted by the City Council ofthe City on September 24, 2015 and pursuant to a Trust Indenture dated as of October 1. 2015. See "INTRODUCTION" in this Official Statement.
Sewer System The Sewer System consists of approximately 4,400 miles of sewers, ranging in size from six inches
lo over 21 feet in diameter, and one sewage lift station. The Sewer System provides sewage and drainage collection and conveyance for a service area of roughly 230 square miles inhabited by approximately 2.7 million people. The City"s Department of Water Management does not operate
any sewage treatment facilities. The Sewer System collects and transmits wastewater to the
ii

treatment facilities of an independent governmental body, the Metropolitan Water Reclamation District of Greater Chicago. Sec "THE WASTEWATER TRANSMISSION SYSTEM."
Sewer System Rates Sewer System rates are set by the City Council. No regulation by any administrative agency applies
to the Sewer System rates. I he Sewer System rates for metered accounts are a percentage of the Water System rates, which in turn arc based on a dollar rate per thousand cubic feet. The assessment of non-metered users is based on a formula related to the size of the relevant property and other use-related factors. Because the Sewer System rates arc calculated as a percentage of the Water System rates, Sewer System rales also increase when Water System rates increase. Sec "FINANCIAL OPERATIONS - Recent Sewer Service Rates." Beginning January 1, 2012. the Water System rates set for that year represented a 25% increase over the rales for the previous year and Sewer System rates increased to 89% of 2012 Water System rates from 86% the previous year; Water System rates in 2013 represented a 15% increase over the previous year and Sewer System rales increased to 92% of 2013 Water System rates; and Water System rates in 2014 represented a 15% increase over the previous year and Sewer System rates increased to 96% of 2014 Water System rates. Water System rates for the year beginning January 1, 2015 have been set by the City Council at a rate representing a 15% increase over rates for 2014, and Sewer System rates were set at 100% of Water System rates and arc scheduled lo remain at 100% of Water System rates. Beginning June 1, 2016, and every year thereafter, annual Water System rates are required to be adjusted, if applicable, by applying to the previous year's rates the rate of inflation, calculated based on the Consumer Price Index - Urban - Wage Earners and Clerical Workers (Chicago All Items) published by the United States Bureau of Labor Statistics for the 365-day period ending on the most recent January 1. Any such annual increase, however, shall be capped at 5% of the previous year's rate. Subject lo applicable rate covenants, the City Council may lake action al any time to alter the then-current schedule of water or sewer rates. See "FINANCIALOPERA I IONS" in the Official Statement.
Use of Bond Proceeds Proceeds from the sale ofthe Bonds will be used to (i) refund certain Line of Credit Notes incurred for
the purpose of converting the City's outstanding Second Lien Wastewater Transmission Variable Rate Revenue Refunding Bonds, Series 2008C (the "Series 2008C Bonds") lo bear interest at fixed rates, including the termination of certain interest rate swaps related to such Series 2008C Bonds, (ii ) make a deposit in the Debt Service Reserve Account for the Bonds, (iii) fund a portion ofthe deposit to the Debl Service Reserve Account for the Series 2008C Bonds, (iv) fund capitalized interest on the Bonds, and (v) pay Costs of Issuance of the Bonds. See "USE OF BOND PROCEEDS."
Investment Considerations There are a number of factors associated with owning the Bonds that prospective investors should
consider prior to purchasing the Bonds. For a discussion of certain of these factors, see "INVESTMENT CONSIDERATIONS".
Trustee Amalgamated Bank of Chicago, Chicago. Illinois, as trustee.
Tax Matters Interest on and profit, if any. on the sale ofthe Bonds are not excludable from gross income for
federal, state or local income tax purposes. See "CERTAIN FAX CONSIDERATIONS."
Delivery and Clearance The Bonds are expected to be available for delivery through DTC on or about October 19. 2015.
Legal Matters Certain legal matters will be passed upon for the parties lo the financing as set forth on the cover
page ofthe Official Statement.
Retirement Funds The City participates in four defined-bencfit retirement funds (collectively, the "Retirement
Funds"). City employees who work for the Department of Water Management participate in one of two of these Retirement Funds: the Municipal Employees' Annuity and Benefit Fund of Chicago ("MEABF") and the Laborers" and Retirement Board Employees' Annuity and Benefit Fund of Chicago ("LABF"'). The City's Retirement Funds have been actuarially determined to be significantly underfunded. The City's contributions to MEABF and LABF (and the Sewer Revenue Fund's share thereof) were scheduled to increase beginning in 2016 (budgeted in 2015) based on the enactment of Public Act 098-641 ("P.A. 98-641"). However, on July 24. 2015. the Circuit Court of Cook County determined P.A. 98-641 to be unconstitutional. The City has appealed this decision to the Illinois Supreme Court. For additional information, see "FINANCIAL OPERATIONS-Pension and Other Post-Employment Benefit Costs" and APPENDIX E-"RETIREMENT FUNDS" in the Official Statement.
The City and the Retirement Funds share the cost of post-employment healthcare benefits available
for certain retired City employees ("Health Plan"). The City has announced plans to phase-out
such benefits by 2017 for certain retirees. Prior to June 30, 2013, the City contributed to the Health
Plan pursuant to a settlement agreement between the City and the Retirement Funds. After
expiration of the settlement, certain of the affected participants filed a lawsuit to reactivate the
litigation covered by the settlement, which lawsuit remains pending. For further information on the
status ofthe Health Plan after June 30, 2013, including certain State and federal litigation relating
to the Health Plan and the settlement agreement, sec APPENDIX E-"RETIREMENT FUNDS-
Payment for Other Post-Employment Benefits" in the Official Statement.

$87,080,000 CITY OF CHICAGO SECOND LIEN WASTEWATER TRANSMISSION REVENUE BONDS, SERIES 2015 (TAXABLE)

INTRODUCTION
This Official Statement, including the cover page, inside cover page, and the Appendices, sets forth certain information in connection with the sale of $87,080,000 Second Lien Wastewater Transmission Revenue Bonds, Series 2015 (Taxable) (the "Bonds"), of the City of Chicago (the "City"), which are to be issued pursuant to the Series 2015 Bond Ordinance. All capitalized terms used in this Official Statement and not otherwise defined herein have the meanings provided in APPENDIX B—"GLOSSARY OF CERTAIN TERMS."
Purposes
The proceeds from the sale of the Bonds will be used to (i) refund certain Line of Credit Notes incurred for the purpose of converting the City's outstanding Second Lien Variable Rate Wastewater Transmission Revenue Refunding Bonds, Series 2008C (the "Series 2008C Bonds") to bear interest at fixed rates, including the termination of certain interest rate swaps related to such Series 2008C Bonds, (ii) make a deposit in the Debt Service Reserve Account for the Bonds, (iii) fund a portion ofthe deposit to the Debt Service Reserve Account for the Series 2008C Bonds, (iv) fund capitalized interest on the Bonds, and (v) pay Costs of Issuance of the Bonds. See "USE OF BOND PROCEEDS."
Authorization; Reoffering of Series 2008C Bonds
The Bonds are being issued pursuant to the constitutional home rule powers of the City. The Bonds were authorized under an ordinance adopted by the City Council on September 24, 2015 (the "Series 2015 Bond Ordinance"). The Bonds are being issued under a Trust Indenture, dated as of October 1, 2015 (the "Indenture"), from the City to Amalgamated Bank of Chicago, Chicago, Illinois, as trustee (the "Trustee").
Concurrently with the issuance of the Bonds, the City currently plans to reoffer $332,230,000 original principal amount of its Series 2008C Bonds. On August 19, 2015, all the outstanding Series 2008C Bonds were converted to a new interest rate, resulting in mandatory tender as provided in the Series 2008C Indenture. Upon tender, the Series 2008C Bonds were purchased by a single direct purchaser. The Series 2008C Bonds, which currently bear interest at a variable rate, are to be reoffered at a fixed rate of interest. Proceeds from the reoffering of the Series 2008C Bonds will be used to pay the principal portion of the purchase price of the mandatorily tendered Series 2008C Bonds, to make a deposit to the Debt Service Revenue Account for the Series 2008C Bonds, and to pay the costs of the reoffering of the Series 2008C Bonds.
Security for the Bonds
The Bonds are limited obligations of the City having a claim for payment of principal and interest solely from the Second Lien Bond Revenues derived by the City from its ownership and operation of the Sewer System, all on an equal and ratable basis with any other Second Lien Bonds. The Bonds are secured by and payable from certain moneys and securities held by the Trustee under the Indenture, including a Debt Service Reserve Account. The Bonds, together with any other Second Lien Bonds, are also secured by and payable from any, amounts on deposit in the Second Lien Construction Accounts. The claim ofthe Bonds to the Net

Revenues Available for Bonds is junior and subordinate to the claim of the City's Senior Lien Bonds and any Senior Lien Parity Bonds. See "SECURITY FOR THE BONDS — General" and "—Flow of Funds," "OUTSTANDING DEBT AND ANNUAL DEBT SERVICE" and APPENDIX C— "SUMMARY OF CERTAIN PROVISIONS OF THE INDENTURE— Source of Payment; Pledge of Second Lien Bond Revenues."

The Bonds are not secured by a lien on or security interest in the physical assets of the Sewer System. The Bonds do not constitute an indebtedness of the City within the meaning of any constitutional or statutory provision or limitation as to indebtedness, and neither the full faith and credit nor taxing power of the City, the State of Illinois or any political subdivision of the State of Illinois is pledged to the payment of the Bonds.
Redemption

The Bonds are subject to redemption prior to maturity as described under the caption "THE BONDS -Redemption."

Rate Covenant
In the Series 2015 Bond Ordinance and the Indenture, the City covenanted to establish, maintain and collect at all times fees, charges and rates for the services provided by the Sewer System sufficient at all times to (a) pay Operation and Maintenance Costs and (b) to produce:
Net Revenues Available for Bonds sufficient to pay the principal of and interest on all Senior Lien Bonds then Outstanding from time to time and to establish and maintain the Bond Principal and Interest Account and the Bond Debt Service Reserve Account as may be covenanted in ordinances authorizing the issuance of Senior Lien Bonds, which Net Revenues Available for Bonds must each Fiscal Year at least equal 115 percent of the sum required to pay promptly when due the debt service for the Fiscal Year on all Senior Lien Bonds then Outstanding,
Second Lien Bond Revenues sufficient to pay the principal of and interest on all Second Lien Bonds then Outstanding from time to time and to establish and maintain the Second Lien Bonds Account as may be covenanted in the ordinances authorizing the issuance of Second Lien Bonds,
amounts sufficient to pay the principal of and interest on all Subordinate Lien Obligations then Outstanding from time to time and to establish and maintain the Subordinate Lien Obligations Account for the Subordinate Lien Obligations as may be covenanted in the ordinances authorizing the issuance of Subordinate Lien Obligations, which amounts must each Fiscal Year at least equal 115 percent of the sum required to pay promptly when due debt service for the Fiscal Year on all Subordinate Lien Obligations Outstanding, and
amounts sufficient to pay the principal of and interest on all Short Term Obligations then Outstanding from time to time and to establish and maintain the debt service account for the Short Term Obligations as may be covenanted in the contracts governing the issuance of Short Term Obligations.
The Indenture provides that these fees, charges and rates shall not be reduced while any Bonds are Outstanding below the level necessary to ensure compliance with the foregoing covenant. See "SECURITY FOR THE BONDS — Second Lien Rate Covenant," "FINANCIAL OPERATIONS — Annual Budget Review and Implementation of Annual Budget", and APPENDIX C — "SUMMARY OF CERTAIN PROVISIONS OF

|1010|
THE INDENTURE — Additional Second Lien Parity Bonds." The City will, prior to the end of each Fiscal Year, conduct a review to determine if it has been and will be in compliance with the rate covenant set forth above. Whenever the annual review indicates that projected Gross Revenues will not be sufficient to comply with the rate covenant, the City will prepare or cause to be prepared a rate study for the Sewer System identifying the rate changes necessary to comply with the rate covenant and the Director of the Office of Budget and Management of the City (the "Budget Director") and the Authorized Officer shall recommend appropriate action to the City Council to comply with this rate covenant, which may include rate increases or expenditure reductions.
Sewer System Rates
Provided that the Rate Covenant is satisfied, the City Council has authority to make other adjustments to sewer service rates. No regulation by any administrative agency applies to the Sewer System rates.

The Sewer System rates for metered accounts are a percentage of the Water System rates, which in turn are based on a dollar rate per thousand cubic feet. The assessment of non-metered users is based on a formula related to the size of the relevant property and other use-related factors. Because the Sewer System rates are calculated as a percentage ofthe Water System rates, Sewer System rates also increase when Water System rates increase. While Sewer System rates had been relatively static for a number of years, beginning in 2008, the City began a series of rate increases designed to align the Sewer rates with the City's water rates. In 2012, the Water System rates set for that year represented a 25% increase over the rates for the previous year and Sewer System rates increased to 89% of 2012 Water System rates from 86% the previous year; Water System rates in 2013 represented a 15% increase over the previous year and Sewer System rates increased to 92% of 2013 Water System rates; and Water System rates in 2014 represented a 15% increase over the previous year and Sewer System rates increased to 96% of 2014 Water System rates. Water System rates for the year beginning January 1, 2015 have been set by the City Council at a rate representing a 15% increase over rates for 2014, and Sewer System rates were set at 100% of Water System rates, an increase from 96% in 2014, and are scheduled to remain at 100% of Water System rates. Beginning June 1, 2016, and every year thereafter, annual Water System rates are required to be adjusted, if applicable, by applying to the previous year's rates the rate of inflation, calculated based on the Consumer Price Index - Urban Wage Earners and Clerical Workers (Chicago All Items) published by the United States Bureau of Labor Statistics for the 365-day period ending on the most recent January 1. Any such annual increase, however, shall be capped at 5% ofthe previous year's rate. Subject to applicable rate covenants, the City Council may take action at any time to alter the then-current schedule of water or sewer rates. See "FINANCIAL OPERATIONS."
Sewer System

The Sewer System consists of approximately 4,400 miles of sewers, ranging in size from six inches to over 21 feet in diameter, and one sewage lift station. The City's Department of Water Management (the "Department") does not operate any sewage treatment facilities. The Sewer System collects and transmits wastewater to the treatment facilities of an independent governmental body, the Metropolitan Water Reclamation District of Greater Chicago (the "Water Reclamation District"). See "THE WASTEWATER TRANSMISSION SYSTEM."

THE BONDS
General

The Bonds will be dated the date of their delivery and will bear interest from that date until paid, payable semiannually on each January 1 and July 1, commencing January 1, 2016. The Bonds will bear interest at the rates per year, and mature in the principal amounts on January 1 in each year, as set forth on the inside cover of this Official Statement. Interest on the Bonds is computed on the basis of a 360-day year consisting of


|1010|
twelve 30-day months. The Bonds will be issued in denominations of $5,000 or integral multiples thereof. The Bonds are subject to redemption prior to maturity, as described below under the heading "—Redemption."

Principal of and interest on the Bonds will be paid by the Trustee. If any payment on any Bonds is due on a day other than a Business Day, it will be made on the next Business Day, and no interest will accrue as a result.

The Bonds initially will be issued through a book-entry only system operated by The Depository Trust Company, New York, New York ("DTC"). Details of payments of the Bonds when in the book-entry form and the book-entry only system are described below under the heading "—Book-Entry Only System." Except as described under the heading "—Book-Entry Only System" below, beneficial owners of the Bonds will not receive or have the right to receive physical delivery of Bonds, and will not be or be considered to be the Owners thereof. Accordingly, each beneficial owner must rely upon (i) the procedures of DTC and, if such beneficial owner is not a DTC "Participant" (as defined below), the Participant who will act on behalf of such beneficial owner to receive notices and payments of principal of and interest on the Bonds, and to exercise voting rights and (ii) the records of DTC and, if such beneficial owner is not a Participant, such beneficial owner's Participant, to evidence its beneficial ownership of the Bonds. So long as DTC or its nominee is the registered Owner of the Bonds, references herein to Bondholders or Owners of such Bonds mean DTC or its nominee and do not mean the beneficial owners of such Bonds.
Redemption
Optional Redemption
The Bonds shall be subject to redemption prior to their maturity at the option of the City, in whole or in part, and if in part, the Bonds shall be selected as described under "Selection of Bonds for Redemption", on any date at a redemption price equal to the greater of:
the principal amount of Bonds to be redeemed, or
the sum ofthe present values of the remaining scheduled payments of principal of and interest on the Bonds to be redeemed, not including any portion of those payments of interest accrued and unpaid as of the date of which the Bonds are to be redeemed, discounted to the date on which the Bonds are to be redeemed, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 50 basis points plus accrued interest on the Bonds being redeemed to the date fixed for redemption. An Authorized Officer shall confirm and transmit the redemption price as so calculated on such dates and to such parties as shall be necessary to effectuate such redemption.

"Treasury Rate" means, with respect to any redemption date for a particular the Bond, the yield to maturity as of such redemption date of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) that has become publicly available for at least two Business Days prior to the redemption date (excluding inflation indexed securities) (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the redemption date to the maturity date of the Bonds to be redeemed; provided, however, that if the period from the redemption date to such maturity date is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used. The Treasury Rate will be determined by an independent accounting firm, investment banking firm or financial advisor retained by the City at the City's expense.

|1010|
General Redemption Procedures
Notice of redemption shall be given by the Trustee by mail, not fewer than 30 days nor more than 60 days prior to the date fixed for redemption, to the Owner of each Bond to be redeemed at the address shown on the registration books of the City kept by the Trustee. Each such redemption notice shall specify: (i) the Bonds to be redeemed by maturity and CUSIP number; (ii) the redemption date; (iii) the place where amounts due upon such redemption will be payable (which shall be the Principal Office of the Trustee); (iv) if fewer than all of the Bonds of any maturity are to be redeemed, the specific Bonds to be redeemed, identified by letters, numbers or other distinguishing marks, and the principal amounts of such Bonds to be redeemed; and (v) that from and after the redemption date, such Bonds shall cease to bear interest. A redemption notice provided in connection with optional redemption may state that the redemption is conditioned on there being on deposit in the Principal and Interest Account on the date fixed for redemption sufficient moneys to pay the redemption price of the Bonds to be redeemed. Such notice may set forth any additional information relating to such redemption as shall be deemed necessary or appropriate by the Trustee.
Failure to duly give notice of redemption by mail to any particular Bondholder, or any defect in such notice, shall not affect the validity of any proceedings for the redemption of Bonds for which such notice has been properly given.
Any Bonds, or portions of Bonds, which have been duly selected for redemption shall be deemed to be paid and shall cease to bear interest on the specified redemption date, if moneys sufficient to pay such Bonds are held by the Trustee for the benefit of the Bondholders.
Selection of Bonds for Redemption
In the event of the redemption of fewer than all the Bonds of the same maturity and interest rate, the aggregate principal amount thereof to be redeemed shall be in an Authorized Denomination, and the Trustee shall assign to each Bond of such maturity and interest rate a distinctive number for each minimum Authorized Denomination of such Bond and shall select by lot from the numbers so assigned as many numbers as, at such minimum Authorized Denomination for each number, equals the principal amount of such Bonds to be redeemed. The Bonds to be redeemed shall be those which were assigned numbers so selected; provided that only so much of the principal amount of each Bond shall be redeemed as shall equal such minimum Authorized Denomination for each number assigned to it and so selected. For purposes of any redemption of fewer than all of the outstanding Bonds of a single maturity and interest rate, the particular Bonds or portions thereof to be redeemed shall be selected not more than 60 days prior to the redemption date by the Trustee. So long as DTC or its nominee is the registered owner of the Bonds, if fewer than all of the Bonds of any maturity and interest rate are called for redemption, the particular Bonds or portions of Bonds of such maturity and interest rate will be selected by lot by DTC in such manner as DTC may determine. See "THE BONDS — Book-Entry Only System."
Bond Registration and Transfers
For a description of the procedure to transfer ownership of a Bond while in the book-entry only system, see "—Book-Entry Only System" below. Subject to the limitations described below, the Bonds are transferable upon surrender thereof at the Principal Office of the Trustee, duly endorsed by, or accompanied by a written instrument or instruments of transfer in form satisfactory to the Trustee and duly executed by the Bondholder or such Bondholder's authorized agent duly authorized in writing. Any Bond, upon surrender of such Bond at the Principal Office of the Trustee, may, at the option of the Bondholder, be exchanged for an equal aggregate principal amount of Bonds of any Authorized Denomination bearing interest at the same interest rate and maturity as the Bond being surrendered. The Trustee may charge a fee sufficient to cover any tax, fee or other governmental charge in connection with any exchange or transfer of any Bond.


|1010|
Book-Entry Only System
The following information has been furnished by The Depository Trust Company for use in this Official Statement, and neither the City nor any of the Underwriters takes any responsibility for its accuracy or completeness.
The Depository Trust Company ("DTC"), New York, New York, will act as securities depository for the Bonds. The 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 Bond certificate will be issued for each maturity of the Bonds, each in the aggregate principal amount thereof set forth herein, 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, as amended (the "Exchange Act"). 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 (the "SEC"). More information about DTC can be found at www.dtcc.com .
Purchases of the Bonds under the DTC system must be made by or through Direct Participants, which will receive a credit for the Bonds on DTC's records. The ownership interest of each actual purchaser of each Bond ("Beneficial Owner") is in turn to 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 of the 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 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 Bonds, except in the event that use of the book entry system for the Bonds is discontinued.
To facilitate subsequent transfers, all 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 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 Owners of the Bonds; DTC's records reflect only the identity of the Direct Participants to whose accounts such 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.


|1010|
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 them, subject to any statutory or regulatory requirements as may be in effect from time to time. Beneficial Owners of the Bonds may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the Bonds, such as redemptions, tenders, defaults, and proposed amendments to the Bond documents. For example, Beneficial Owners of the Bonds may wish to ascertain that the nominee holding the 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 Bonds of a maturity are being redeemed, DTC's practice is to determine by lot the amount of the interest of each Direct Participant in the Bonds to be redeemed.
Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to the 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 Bonds are credited on the record date (identified in a listing attached to the Omnibus Proxy).
Redemption proceeds, distributions, and interest payments on the 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, distributions, and interest payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of the 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 Bonds at any time by giving reasonable notice to the City or the Trustee. Under such circumstances, in the event that a successor securities depository is not obtained, certificates for the 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 Bonds will be printed and delivered to DTC.
Additional Information
For every transfer and exchange of the Bonds, DTC, the Trustee 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.
NEITHER THE CITY NOR THE TRUSTEE WILL HAVE ANY RESPONSIBILITY OR OBLIGATION TO ANY PARTICIPANTS, OR TO THE PERSONS FOR WHOM THEY ACT AS NOMINEES WITH RESPECT TO THE BONDS, OR TO ANY BENEFICIAL OWNER IN RESPECT OF THE ACCURACY OF ANY RECORDS MAINTAINED BY DTC OR ANY PARTICIPANT OR INDIRECT PARTICIPANT OF ANY AMOUNT IN RESPECT OF THE PRINCIPAL OF OR INTEREST ON THE BONDS, OR ANY NOTICE WHICH IS PERMITTED OR REQUIRED TO BE GIVEN WITH RESPECT TO

|1010|
THE BONDS, INCLUDING ANY NOTICE OF REDEMPTION OR OTHER ACTION TAKEN, BY DTC AS REGISTERED OWNER OF THE BONDS.
The City is entitled to treat Owners as absolute owners of the Bonds for the purpose of paying principal, interest and redemption price.
In reading this Official Statement it should be understood that while the Bonds are in the Book-Entry Only System, references in other sections of this Official Statement to registered owners should be read to include the person for which a Participant acquires an interest in the Bonds, but (a) all rights of ownership must be exercised through DTC and the Book-Entry Only System and (b) notices that are to be given to registered owners will be given only to DTC.
General Provisions of the Bonds When Not in Book-Entry Only System

During any period in which the Bonds are not registered in the name of DTC or its nominee, the principal of all Bonds and the Redemption Price, if any, of all Bonds (and the interest payable on any date of redemption other than on an Interest Payment Date) shall be payable at the Principal Office of the Trustee, which is the paying agent for the Bonds. Interest on the Bonds payable on any Interest Payment Date shall be payable by check mailed by the Trustee to the registered owners ofthe Bonds at their addresses as shown on the registration books of the City maintained by the Trustee. The interest payable on the Bonds on each Interest Payment Date will be paid to the persons in whose names the Bonds are registered as of the applicable Record Date. Upon request of a registered owner of at least $1,000,000 outstanding principal amount of the Bonds, all payments of interest on all Bonds shall be paid by wire transfer in federal funds to an account in the continental United States designated by such registered owner. The principal and Redemption Price of each Bond shall be payable in clearinghouse funds upon surrender of such Bond at the Principal Office of the Trustee. The Bonds may be transferred or exchanged for the same total principal amount of Bonds of the same maturity of other Authorized Denominations upon surrender at the Principal Office of the Trustee, together with an assignment executed by the registered owner or by the registered owner's duly authorized agent. Payment of any tax, fee or other governmental charge, other than one imposed by the City, arising from any transfer or exchange of Bonds may be required to be paid by the registered owner as a condition for exercising that privilege. Neither the City nor the Trustee will be required to transfer any Bond during the 15 days next preceding an Interest Payment Date or, in the case of a proposed redemption of the Bonds, after the selection by the Trustee of such Bonds for redemption. In the event any Bond is mutilated, lost, stolen or destroyed, the City shall execute and the Trustee shall authenticate a new Bond upon satisfaction of the provisions of the Indenture.

USE OF BOND PROCEEDS
Use of Proceeds

Simultaneously with the issuance of the Bonds, the City is converting the Series 2008C Bonds from a variable rate of interest to fixed interest rates. As part of this conversion, the City expects to use Line of Credit Note proceeds to pay the costs of terminating the interest rate swap agreements related to the Series 2008C Bonds. Proceeds from the Bonds are expected to be used to refund the Line of Credit Notes used for the swap termination. In addition, proceeds from the Bonds will be used to make a deposit into the Debt Service Reserve Account for the Bonds, fund a portion of the deposit into the Debt Service Reserve Account for the Series 2008C Bonds, fund capitalized interest on the Bonds, and pay the Costs of Issuance of the Bonds.

SECURITY FOR THE BONDS
General
The Bonds are limited obligations of the City and do not constitute an indebtedness of the City within the meaning of any constitutional or statutory provisions or limitations as to indebtedness, and have no claim to be paid from taxes of the City. As described below, the Bonds, together with the Outstanding Second Lien Bonds, including any Second Lien Parity Bonds issued from time to time in the future, are secured by a pledge of Second Lien Bond Revenues that are derived from the Net Revenues Available for Bonds (as defined below) in the City's Sewer Revenue Fund, which claim is junior and subordinate to the claim of the Outstanding Senior Lien Bonds and any Senior Lien Parity Bonds. See "Flow of Funds—4. The Second Lien Bonds Account," below.

"Net Revenues Available for Bonds" means that portion of Net Revenues remaining in any period, minus any amounts deposited during that period in the Sewer Rate Stabilization Account as provided in the Series 2015 Bond Ordinance (other than amounts transferred to that Account from amounts received upon the issuance of any Senior Lien Parity Bonds) and plus the amounts withdrawn during that period from that Account. "Net Revenues" means that portion of the Gross Revenues remaining in any period after providing sufficient funds for Operation and Maintenance Costs. The terms "Gross Revenues" and "Operation and Maintenance Costs" have the meanings set forth in APPENDIX B—"GLOSSARY OF CERTAIN TERMS."
Pledge of Second Lien Bond Revenues
The Bonds are payable on a parity basis as to Second Lien Bond Revenues with all other Outstanding Second Lien Bonds, including any Second Lien Parity Bonds issued from time to time in the future. Second Lien Bond Revenues consist of all Net Revenues Available for Bonds deposited into the Second Lien Bonds Account pursuant to the Series 2015 Bond Ordinance and the ordinances authorizing each prior series of Outstanding Second Lien Bonds and each series of Outstanding Second Lien Parity Bonds. On the Business Day immediately preceding each January 1 and July 1, the Authorized Officer is required to transfer to the Trustee for deposit into the Second Lien Bonds Account the amounts required by the Indenture and any ordinance authorizing the issuance of Second Lien Bonds. Pursuant to the Indenture, such Second Lien Bond Revenues are pledged to the payment of the principal of and interest on the Bonds and all other Outstanding



10

Second Lien Bonds, without priority or distinction of one series of Second Lien Bonds over any other series of Second Lien Bonds. See "Flow of Funds —4. The Second Lien Bonds Account," below.
Pledge of Amounts in Second Lien Construction Accounts
The Bonds, together with any other Outstanding Second Lien Bonds, are also secured by and payable from any amounts on deposit in the Second Lien Construction Accounts.
Flow of Funds
The City maintains the Sewer Revenue Fund as a separate fund of the City to, among other things, carry out the provisions of the ordinances authorizing the Senior Lien Bonds, the Second Lien Bonds, any Subordinate Lien Obligations, any Commercial Paper Notes or any Line of Credit Notes. All Gross Revenues of the Sewer System are credited as they are collected to the Sewer Revenue Fund, which is held by a depository bank which is currently not the depository for the City's General Fund. Net Revenues Available for Bonds are required pursuant to the Series 2015 Bond Ordinance to be deposited in the following accounts in the following order of priority:
The Bond Principal and Interest Account is used to pay principal of, redemption premium, if any, and interest on the Outstanding Senior Lien Bonds and amounts owed on Interest Rate Hedge Agreements for Outstanding Senior Lien Bonds. At least 10 days before each date that such debt service payments are due with respect to Senior Lien Bonds, sufficient amounts to make such payments shall be deposited into this Account.
The Bond Debt Service Reserve Account is used to pay principal of, redemption premium, if any, and interest on the Outstanding Senior Lien Bonds as the same become due at any time when there are insufficient funds available for such purpose in the Bond Principal and Interest Account (after any available amounts in the Sewer Rate Stabilization Account have first been applied to that purpose, excluding amounts in excess of the Bond Debt Service Reserve Requirement for Outstanding Senior Lien Bonds), except to the extent required to be credited to the Senior Lien Rebate Accounts. The Bond Debt Service Reserve Requirement for Outstanding Senior Lien Bonds is currently met by a municipal bond debt service reserve fund policy, as shown in the table below. The City is required to deposit funds from the Sewer Revenue Fund into the Bond Debt Service Reserve Account to repay any draws made under that policy.
The Senior Lien Rebate Accounts are used to make required rebates of arbitrage to the United States with respect to any Senior Lien Bonds.
The Second Lien Bonds Account is used to pay the principal of and interest on the Bonds and any other Outstanding Second Lien Bonds. The City also is required to make deposits in the Second Lien Bonds Account to meet other payment obligations under the Indenture and any ordinance or indenture authorizing Outstanding Second Lien Bonds. The City will make debt service and other deposits as required by the Indenture and by any ordinance or indenture authorizing Outstanding Second Lien Bonds. Moneys deposited in the Second Lien Bonds Account shall be transferred by the Authorized Officer on the date so deposited to the Trustee and the trustee or paying agent for each series of Second Lien Bonds in order to satisfy the debt service and other payment obligations, including with respect to Interest Rate Hedge Agreements, under the Indenture and any ordinance or indenture authorizing such Outstanding Second Lien Bonds. Moneys on deposit in the Second Lien Bonds Account shall be applied without priority as to any particular series of Outstanding Second Lien Bonds.






11

The City has established Debt Service Reserve Accounts for certain Series of Outstanding Second Lien Bonds. Each Debt Service Reserve Account secures only the Series of Outstanding Second Lien Bonds for which it was established. The Debt Service Reserve Requirement for certain Series of Outstanding Second Lien Bonds is or will be met by separate municipal bond debt service reserve fund policies and by cash deposits, as shown in the table below. The Debt Service Reserve Requirement for the Bonds, and for the Series 2008C Bonds, will be funded with cash upon the issuance of the Bonds and the Series 2008C Bonds.
The Subordinate Lien Obligations Account is used to make debt service payments and other required deposits with respect to any outstanding Subordinate Lien Obligations. As of the date of this Official Statement, the only Subordinate Lien Obligations outstanding are certain loans by the Illinois Environmental Protection Agency ("IEPA"). See "OUTSTANDING DEBT AND ANNUAL DEBT SERVICE-Subordinate Obligations." The City is obligated to make required debt service and other deposits in the Subordinate Lien Obligations Account on the Business Day immediately preceding each January 1 and July 1. Moneys on deposit in the Subordinate Lien Obligations Account shall be applied without priority to any subaccounts established in the Subordinate Lien Obligations Account, as directed by a certificate of the Authorized Officer.
The Commercial Paper and Line of Credit Account is used for the purpose of paying such amounts as may be required to be paid by the related trust indentures governing Commercial Paper Notes, and for the purpose of paying such amounts as may be required to be paid by the related line of credit agreement governing such Line of Credit Notes.
The Sewer Rate Stabilization Account is used at the City's discretion, in any year, to pay any expenses of or obligations of the Sewer System, including, without limitation, Operation and Maintenance Costs, deposits in the Bond Principal and Interest Account, deposits in the Bond Debt Service Reserve Account, deposits when due in the Second Lien Bonds Account (but only if and to the extent no amounts are required to be deposited in the Bond Principal and Interest Account and the Bond Debt Service Reserve Account), deposits when due in the Subordinate Lien Obligations Account (but only if and to the extent no amounts are required to be deposited in the Bond Principal and Interest Account, the Bond Debt Service Reserve Account or the Second Lien Bonds Account), deposits when due in the Commercial Paper and Line of Credit Account (but only if and to the extent no amounts are required to be deposited in the Bond Principal and Interest Account, the Bond Debt Service Reserve Account, the Second Lien Bonds Account, or the Subordinate Lien Obligations Account), the costs of any Interest Rate Hedge Agreements or other similar arrangement or any costs of repairs, replacements, renewals, improvements, equipment or extensions to the Sewer System. The Sewer Rate Stabilization Account must be used to make all required deposits to the Bond Principal and Interest Account and the Bond Debt Service Reserve Account when no other funds are available for that purpose. Any Net Revenues remaining in any period and not required to be deposited in the Bond Principal and Interest Account, the Bond Debt Service Reserve Account, any Senior Lien Rebate Account, the Second Lien Bonds Account, the Subordinate Lien Obligations Account, or the Commercial Paper and Line of Credit Account may be transferred to the Sewer Rate Stabilization Account at any time upon the direction of the Authorized Officer. For more information concerning the Sewer Rate Stabilization Account, see "FINANCIAL OPERATIONS — Historical and Projected Operations."

Sewer Rate Stabilization Account


Any funds available in the Sewer Revenue Fund after the requirements above have been satisfied or which are not necessary to satisfy such requirements may be used for any lawful purpose of the Sewer System. Funds in the Accounts in the Sewer Revenue Fund established in the Series 2015 Bond Ordinance must be invested in Permitted Investments. All amounts in the Bond Debt Service Reserve Account and each Senior Lien Rebate Account must be invested in Permitted Investments that are held separate and distinct from those of any other Funds or Accounts. Investments shall be scheduled to mature before needed for the respective purposes of each of such accounts. All investment earnings on any such Accounts so invested must be credited to the Sewer Revenue Fund and shall be considered Gross Revenues, except that earnings on the investment of amounts on deposit in the Senior Lien Rebate Accounts shall not be considered Gross Revenues and shall be retained in the respective Senior Lien Rebate Accounts except to the extent no longer required for rebate purposes.
The Series 201 OB Second Lien Bonds are qualified "Build America Bonds" for purposes of the American Recovery and Reinvestment Act of 2009 (the "Recovery Act"), which allowed the City to receive Federal Subsidies from the United States Treasury in connection with such bonds. Because Build America Bonds did not exist at the time of the original flow of funds structure, such Federal Subsidies were not contemplated and have never been included in the flow of funds. Thus, Gross Revenues of the Sewer System in the table above do not include any such Federal Subsidy payments, so the Federal Subsidies that may be received by the City are not required to be deposited by the City into the Sewer Revenue Fund. Accordingly, such Federal Subsidies do not constitute security for, and are not available for payment of, the Series 2015 Bonds or any other Second Lien Bonds, nor any Senior Lien Bonds, Subordinate Lien Obligations, or Short Term Obligations.

Debt service reserves are available only for the respective series of bonds for which they were established. As a result ofthe widespread losses in the mortgage market and overall credit market challenges, among others, the Debt Service Reserve Providers may experience claims and/or reductions in capital such that their capital resources may no longer be sufficient at their respective rating levels lo meet their ongoing additional capital needs and/or to respond to claims, including claims under ihe credit instruments issued for the benefit ofthe respective Debt Service Reserve Accounts. In the event of a ratings downgrade or withdrawal, the City is under no obligation to replace the applicable credit instruments with cash or another credit instrument. Formerly known as MBIA. Formerly known as FGIC.
Funded with proceeds ofthe Bonds and the Series 2008C Bonds. Funded with proceeds of the Bonds.

Payment of Debt Service on the Bonds
The Indenture establishes the 2015 Second Lien Bonds Revenue Fund to be held and administered by the Trustee. Under the Indenture, the Authorized Officer is required on the Business Day preceding each January 1 and July 1 to transfer to the Trustee for deposit in the 2015 Second Lien Bonds Revenue Fund the amounts required to be deposited in such account from amounts on deposit in the Second Lien Bonds Account. The Indenture establishes a Principal and Interest Account within the 2015 Second Lien Bonds Revenue Fund. Moneys on deposit in the Principal and Interest Account will be held by the Trustee for the sole and exclusive benefit of the Bonds and used for the purpose of paying the principal of and interest on such Bonds as it becomes due.
Debt Service Reserve Account

The Indenture establishes a Debt Service Reserve Account which the City is required to maintain in an amount equal to the Debt Service Reserve Requirement for the Bonds. The Debt Service Reserve Requirement means, as of any date of computation, an amount equal to the least of: (1) 10% of the stated principal amount of the Bonds, (2) 100% of maximum Annual Second Lien Debt Service with respect to the Bonds in the current or any future Fiscal Year, and (3) 125% of the average Annual Second Lien Debt Service with respect to the Bonds in the current and any future Fiscal Year. The Debt Service Reserve Requirement for the Bonds as of the date of issuance will be $6,952,642.

Second Lien Rate Covenant
In the Series 2015 Bond Ordinance and the Indenture, the City covenanted for the benefit of the Owners of the Bonds, to establish, maintain and collect at all times fees, charges and rates for the services provided by the Sewer System sufficient at all times to (a) pay Operation and Maintenance Costs and (b) produce (i)Net Revenues Available for Bonds sufficient to pay the principal of and interest on all Senior Lien Bonds then Outstanding from time to time and to establish and maintain the Bond Principal and Interest Account and the Bond Debt Service Reserve Account as may be covenanted in ordinances authorizing the issuance of Senior Lien Bonds, which Net Revenues Available for Bonds must each Fiscal Year at least equal one hundred fifteen percent of the sum required to pay promptly when due the debt service for the Fiscal Year on all Senior Lien Bonds then Outstanding, (ii) Second Lien Bond Revenues sufficient to pay the principal of and interest on all Second Lien Bonds then Outstanding from time to time and to establish and maintain the Second Lien Bonds Account as may be covenanted in the ordinances authorizing the issuance of Second Lien Bonds, (iii) amounts sufficient to pay the principal of and interest on all Subordinate Lien Obligations then Outstanding from time to time and to establish and maintain the Subordinate Lien Obligations Account for the Subordinate Lien Obligations as may be covenanted in the ordinances authorizing the issuance of Subordinate Lien Obligations, which amounts must each Fiscal Year at least equal one hundred fifteen percent of the sum required to pay promptly when due debt service for the Fiscal Year on all Subordinate Lien Obligations Outstanding, and (iv) amounts sufficient to pay the principal of and interest on all Short Term Obligations then Outstanding from time to time and to establish and maintain the debt service account for the Short Term Obligations as may be covenanted in the contracts governing the issuance of Short Term Obligations. The Indenture provides that these fees, charges and rates may not be reduced while any 2015 Second Lien Bonds are Outstanding below the level necessary to ensure compliance with the foregoing covenant.
The City will, prior to the end of each Fiscal Year, conduct a review to determine if it has been and will be in compliance with the rate covenant set forth above. Whenever the annual review indicates that projected Gross Revenues will not be sufficient to comply with the rate covenant, the City will prepare or cause to be prepared a rate study for the Sewer System identifying the rate changes necessary to comply with the rate covenant and the Director ofthe Office of Budget and Management of the City (the "Budget Director") and the Authorized Officer shall recommend appropriate action to the City Council to comply with this rate covenant, which may include rate increases or expenditure reductions.
Additional Second Lien Parity Bonds
Additional Second Lien Parity Bonds may be issued, as provided in the Indenture, for any lawful purpose of the Sewer System, including to refund Outstanding Senior Lien Bonds, Second Lien Bonds, Subordinate Lien Obligations, Commercial Paper Notes, or Line of Credit Notes, in each case upon compliance with certain conditions set forth in the Indenture. See APPENDIX C— "SUMMARY OF CERTAIN PROVISIONS OF THE INDENTURE — Additional Second Lien Parity Bonds."
Additional Information

For an additional description ofthe requirements that must be satisfied for the City to issue Second Lien Parity Bonds and other terms of the Indenture, see APPENDIX C— "SUMMARY OF CERTAIN PROVISIONS OF THE INDENTURE."
Deficiencies and Excesses
In the event of a deficiency in any Fiscal Year in the Bond Principal and Interest Account, the Bond Debt Service Reserve Account, any Senior Lien Rebate Account, the Second Lien Bonds Account, the Subordinate Lien Obligations Account, or the Commercial Paper and Line of Credit Account, the amount of such deficiency shall be included in the amount to be transferred from the Sewer Revenue Fund and deposited


15

into such account during the next 12-month period or succeeding Fiscal Year. Whenever the balance in the Bond Debt Service Reserve Account or any Senior Lien Rebate Account exceeds the amount required to be on deposit in such account, the excess may be transferred to the Sewer Revenue Fund, provided that no such transfers shall be made when any debt service payments on outstanding obligations of the City (including the Bonds) that are payable by their terms from the revenues of the Sewer System are past due. Any funds that remain in the Sewer Revenue Fund at the end of any Fiscal Year shall be retained in the Sewer Revenue Fund and shall be available for appropriation for any proper purpose of the Sewer System.

Cash and Investments
Any cash or investments in the Bond Debt Service Reserve Account and Senior Lien Rebate Account shall be held pursuant to depository agreements in separate bank, accounts and in separately identifiable investments as described below under the heading "—Investment of Funds." The remainder of all amounts in the Sewer Revenue Fund, including amounts for payment of debt service on the Bonds and any Senior Lien Parity Bonds and Second Lien Parity Bonds prior to their deposit in the Bond Principal and Interest Account or the Second Lien Bonds Account, is deposited in bank accounts and invested on a commingled basis with a variety of other funds of the City, including the General Fund. The amounts which are commingled and invested as described above are referred to as the City's "consolidated cash." Consolidated cash may be used for interfund borrowings among various funds of the City, including, but not limited to, the Sewer Revenue Fund, and such use reduces the need for external borrowing by the City to meet the needs of the Sewer Revenue Fund and other funds of the City. The City has maintained its consolidated cash, including interfund borrowing by the Sewer Revenue Fund, so as to meet the obligations of the Sewer Revenue Fund in a timely fashion.
The investment of City funds is governed by the City's Municipal Code, which provides that neither the City Comptroller nor the City Treasurer has the authority, without City Council approval, to "... (i) invest in arrangements whose returns are linked to or derived from the performance of some underlying asset such as bonds, currencies or commodities or (ii) borrow against or otherwise obligate City investments for the purpose of investment." See APPENDIX A—"CITY OF CHICAGO, ILLINOIS SEWER FUND BASIC FINANCIAL STATEMENTS AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2014 AND 2013, STATISTICAL DATA, AND INDEPENDENT AUDITORS' REPORT—Notes (1) and (2)." In the Series 2015 Bond Ordinance, the City Council granted such approval in connection with the plan of financing for the Bonds. In accordance with the requirements of the Public Funds Investment Act enacted by the State, the City Council has adopted a Statement of Investment Policy and Guidelines for the purpose of establishing written cash management and investment guidelines to be followed by the Office of the City Treasurer in the investment of City funds in accordance with the Municipal Code.

Investment of Funds
Funds in the accounts described above under the heading "Flow of Funds" and in the accounts established under the Indenture are required to be invested in Permitted Investments upon the direction of the Authorized Officer. Investments must be scheduled to mature before needed for the respective purposes of each of such accounts. All Investment Earnings on any such accounts so invested are credited to the Sewer Revenue Fund and are considered Gross Revenues; provided, however, that earnings on the investment of amounts on deposit in the Senior Lien Rebate Accounts shall not be Investment Earnings, shall not be considered Gross Revenues, and will be retained in the respective Senior Lien Rebate Accounts, except to the extent no longer required for rebate purposes.

Subordinate Obligations
The City has entered into loan agreements with the I EPA as shown in the following table, to fund Sewer System projects. Each loan constitutes a Subordinate Lien Obligation. It is anticipated that the City will enter into additional IEPA loans in the future. Subordinate Lien Obligations, including the IEPA loans, have a claim to payments from amounts in the Sewer Revenue Fund that is subordinate to the claim of the Bonds.

Outstanding principal amounts as of December 31, 2014.
This total docs not include two pending IEPA loans. The first loan in the maximum amount of $54,000,000. with an interest rate of 1.93% and an estimated maturity date of 2036, is expected to close prior lo February 1, 2016. I he second loan in the maximum amount of $60,000,000, with an interest rale of 1.995% and an estimated maturity date of 2037, is expected to close prior to February 1. 2017. Until the terms of each loan are finalized, the exact amount ofthe loan, the debt service schedule, and the maturity date are not set.
The Series 2012 Bond Ordinance authorized the issuance from time to time of Commercial Paper Notes and Line of Credit Notes for the purposes of financing or refinancing capital improvements to the Sewer System or providing funds to meet the cash flow needs of the Sewer System, among others. The maximum aggregate principal amount of all Commercial Paper Notes and Line of Credit Notes outstanding at any one time may not exceed $150,000,000, without further authorization from the City Council. The claim of any Commercial Paper Notes or Line of Credit Notes for payment from moneys in the Sewer Revenue Fund is subordinate to the claim of the Bonds. The City entered into a Wastewater Revolving Credit Agreement for up to $75 million between the City and Morgan Stanley Bank, N.A. on October 2, 2015, payable from the Commercial Paper and Line of Credit Account (the "2015 Line of Credit Agreement"). Other than the Line of Credit Notes issued pursuant to the 2015 Line of Credit Agreement, which the C ity is using to terminate the swap agreements entered into by the City related to the Series 2008C Bonds and which Line of Credit Notes are to be refunded with a portion of the proceeds of the Bonds, the City currently has no other program in place for the issuance of Commercial Paper Notes or Line of Credit Notes pursuant to this authorization. The City expects to have $70,243,000 of Line of Credit Notes outstanding as of October 16, 2015, and to repay the Line of Credit with proceeds from the Bonds.
Swaps
As previously noted, the City entered into certain interest rate swaps as a means of limiting, reducing or managing the City's interest cost with respect to the Series 2008C Bonds, thereby limiting the interest rate risk inherent in variable rate debt.

The City has now decided to convert the Series 2008C Bonds from variable rate debt to bonds bearing interest at fixed interest rates and as part of that conversion has terminated the interest rate swaps for the Series 2008C Bonds through the application of funds provided through Line of Credit Notes, which Line of Credit Notes are to be refunded with a portion of the proceeds of the Bonds. On October 8, 2015, the swap with Bank of America, N.A. in the notional amount of $49,835,000 was terminated with a payment of $11,248,000. On October 9, 2015, the swap with Deutsche Bank in the notional amount of $232,560,000 was terminated with

a payment of $47,720,000, and the swap with JPMorgan Chase Bank, N.A. in the notional amount of $49,835,000 was terminated with a payment of $11,275,000.
THE WASTEWATER TRANSMISSION SYSTEM
General
The Sewer System provides sewage and drainage collection and conveyance for a service area of roughly 230 square miles inhabited by approximately 2.7 million people.
The Sewer System was designed and constructed as a combined system to provide for collection and conveyance of both sanitary sewage and storm water run-off in common sewer conduits. The Sewer System is not responsible for, and does not include any facilities for, the treatment or disposal of sewage. It is limited to collecting and conveying wastewater to the interceptor sewers of the Water Reclamation District, an independent government entity with exclusive responsibility for sewage treatment, sewage disposal and flood control in the City and neighboring suburbs. The Water Reclamation District is charged with providing and managing the facilities for the collection (through a network of approximately 536 miles of intercepting sewers and force mains), treatment and subsequent disposal of sewage from the City and surrounding areas. The Water Reclamation District finances its operations primarily through the imposition of an ad valorem tax in the area that it serves.
The City is solely responsible for the Sewer System except with respect to direct connections to rivers and waterways, in which case approval must be obtained from the Water Reclamation District or the U.S. Army Corps of Engineers, and direct connections to the Water Reclamation District, in which case approval must be obtained from the Water Reclamation District.
There are no significant areas of the City without sewer service and, except for a very limited number of industrial users who have direct connections to the Water Reclamation District's interceptors, connection to the Sewer System is the only feasible means of wastewater disposal for nearly all City users. By regulation of the Department, all sewer work performed within the City or connecting to the Sewer System or to the City's waterways, whether on public or private property, is subject to approval by the Department.
The following table shows the population of the City for the past five decades:
Sewer System Service area Population

Source: U.S. Census Bureau. Organization and Staffing
The Department is an executive department of the City with responsibility for the operation, maintenance, repair, improvement and extension of the City's Water and Sewer Systems. Separate funds are maintained for the water and sewer payments made to the Department.




20

The chief administrator of the Department is the Commissioner, who is appointed by the Mayor with the approval of the City Council. Under the direction of the Commissioner, the Department is organized into five bureaus and the Commissioner's office as follows:
Commissioner's Office: The office is responsible for the oversight and management of general and project-specific initiatives for the other bureaus. This office also includes security and safety.
Administrative Support: This bureau is responsible for the collection and dissemination of all financial information, procurement and contract administration, personnel, labor relations, information technology and payroll.
Operations and Distribution: This bureau is responsible for the maintenance, repair and installation of water and sewer mains and appurtenances, including valves, fire hydrants, manholes, catch basins and valve basins.
Water Supply: This bureau is responsible for the treatment, purification, pumping and monitoring the quality and purity of the water supply.
Engineering Services: This bureau is responsible for providing engineering and inspection support for the planning, design, expansion, rehabilitation, operating, monitoring and inspection of the Water and Sewer Systems.
Meter Service: This bureau is responsible for water meter installation, reading and repair.
The employment level of the Department as of December 31, 2014 consisted of 1,504 Water Fund employees and 591 Sewer Fund employees. This represents the total number of employees on the Department's payroll and excludes leaves of absences and duty disability. The Department includes employees with professional qualifications in the fields of engineering, law, science, construction management, public sector management and financial management, as well as skilled technical personnel. Most of the Department's employees are covered by collective bargaining agreements that expire on June 30, 2017.
The City maintains a self-insurance program, including casualty coverage, general liability coverage and workers' compensation for the Department. The City also maintains replacement-cost property insurance that covers the major facilities of the Sewer System.
Description of Physical Facilities

The Sewer System consists of approximately 4,400 miles of sewers, ranging in size from six inches to over 21 feet in diameter, and one sewage lift station. The tables below provide a profile of the transmission facilities of the Sewer System by size, age and length:

These wastewater collection and transmission facilities primarily operate as a gravity system. However, one lift station serving lower elevations in the Hegewisch service area is incorporated in the Sewer System because gravity flow is not feasible in that service area. The lift station was completed in 1982 and is fully automated. The lift station is in excellent condition and is designed to handle the combined run-off for the existing drainage area.
Capital Improvement Program
The City, through the Department, continually improves and rehabilitates the Sewer System. To provide for future additions to the Sewer System, replacement of facilities and rehabilitation of existing facilities, the Department has prepared a projected capital improvement program covering a ten-year period from 2012 to 2021 (the "Capital Improvement Program"). The Capital Improvement Program is currently on schedule and within budget. Over its ten-year period, the Capital Improvement Program is projected to replace 250 miles of sewer mains, line 490 miles of sewer main, line 140,000 sewer structures, and create 9,000 jobs. These figures, which are approximate and subject to change, reflect the Department's proposed expenditures for capital improvements over the course of the Capital Improvement Program. Actual expenditures are subject to annual approval of the City of Chicago Office of Budget and Management.
The City replaced 17 miles of sewer main in 2012, an additional 17 miles of sewer main in 2013, and an additional 22 miles of sewer main in 2014, and expects to replace an additional 22 miles in 2015, an additional 22 miles in 2016 and an additional 29 miles in 2017. The ongoing projects of the Department will insure continued economic and reliable delivery of sewer services. The Department may revise the list of specific improvements and revise cost allocations among improvements, as well as make substitutions to meet current needs and to provide for the efficient operation of the Sewer System. Under the Capital Improvement Program, it is expected that approximately 18 percent of the 2016 and 2017 projects will be funded from net revenues of the Sewer System with the remainder funded from IEPA State Revolving Loan Funds and the sale of indebtedness ofthe Sewer System.
The Sewer System's planned expenditures for the 2015-2019 portion of the Capital Improvement Program are summarized in the table below. The information presented in the table reflects the Department's expected allocations of resources to various projects, but does not necessarily represent an expectation of actual cash expenditures for these projects, which are subject to annual approval of the City of Chicago Office of Budget and Management. The primary sources of funds to undertake these projects are expected to be proceeds from contemplated debt issuances, including IEPA loans, as well as funding from current sewer revenue (also referred to as "pay-go"). See "FINANCIAL OPERATIONS — Historical and Projected Operations."

The Department has applied for and received funding from the IEPA Clean Water Initiative State Revolving Loan Fund Program. This program provides loans for a twenty-year repayment term in most instances with shorter repayment schedules negotiated under certain project circumstances. The loans, which are Subordinate Lien Obligations, are provided at simple interest and payback does not begin until the completion of the construction. Interest rates for the program are established annually, and are calculated and applied at one-half the Bond Market Interest Rate, defined as the mean interest rate of the Bond Buyer 20 Bond General Obligation Index for the preceding fiscal year. The interest rate in effect at the time of origination remains fixed for the life of the loan. See "OUTSTANDING DEBT AND ANNUAL DEBT SERVICE-Subordinate Obligations."
USEPA
In 1975, the Water Reclamation District began the construction of its Tunnel and Reservoir Plan ("TARP") project to address combined sewer overflows ("CSOs") in the metropolitan Chicago area. Tunnel systems have been completed. The project will be completed upon the final completion of the reservoirs, which is expected to be in 2029.
In 2004, the United States Environmental Protection Agency ("USEPA") requested information from the Department concerning the City's compliance with regulatory requirements under the Clean Water Act pertaining to CSOs in Chicago area waterways. Overflows may occur when the combined flow of storm water run-off and sanitary sewage exceeds the capacity of the Sewer System and the sewage collection and treatment facilities of the Water Reclamation District.
The City provided a comprehensive response to the USEPA's request in February 2005 describing its compliance with applicable CSO requirements. Since 2008, the USEPA has requested additional information specifically pertaining to CSOs (control of floatables) from the City, but has not required any additional remedial action to be taken by the City or indicated an intention to pursue an enforcement action against the City. To date, no enforcement proceedings against the City have been instituted by the USEPA, and the Department does not currently anticipate that such a proceeding would be filed.
The Department receives requests for information from USEPA regarding CSOs and related issues from time to time, to which it responds. The NPDES permit for City CSO outflows is currently being renewed. Various environmental groups have submitted comments to the IEPA objecting to the proposed permit, but have not filed any citizen suit 60-day notice letter or litigation. According to the USEPA-MWRD CSO settlement, approved by federal district and circuit courts, the currently projected completion date for the TARP project is now 2029.

FINANCIAL OPERATIONS

Recent Sewer Service Rates
Revenues from sewer service charges provide funds for the operation, maintenance and debt service of the Sewer System. The Sewer Revenue Fund receives no share of any state or local property or income taxes.
Sewer service rates are set by ordinance. The sewer service charge is established in an amount designed to pay the costs of Sewer System operations and capital improvements, including any related debt service. The current charge for sewer service is an amount equal to 100 percent of the gross amount charged for water service, whether such water service is metered or nonmetered.
Historical rates are shown in the following table. The sewer rate is now equal to the water rate. By ordinance annual Water System rates are now automatically adjusted by applying to the previous year's rates the rate of inflation, calculated based on the Consumer Price Index-Urban Wage Earners and Clerical Workers (Chicago All Items) published by the United States Bureau of Labor Statistics for the 365-day period ending on the most recent January 1. Such increases do not require further action by the City Council. Any such automatic annual increase, however, shall be capped at 5% of the previous year's rate. Because the sewer rate is now equal to the water rate, sewer rates would also increase based on any increase in the consumer price index beginning June 1, 2016, and every year thereafter. Subject to applicable rate covenants, the City Council may take action at any time to alter the then-current schedule of water or sewer rates.

Sewer Accounts
As of December 31, 2014, the Sewer System supplied 428,752 accounts, net of 62,856 exempt accounts. The number of nonmetered accounts exceeds the number of metered accounts by 9,000 because all single-family and two-family dwellings within the City were serviced as nonmetered accounts prior to 1982. Pursuant to an ordinance adopted in 1982, all new water accounts, regardless of character, and all new services to existing water accounts are required to be metered. Since 2009, the Department's MeterSave Program has installed approximately 15,000 new meters annually. Senior citizens age 65 and older who reside in their own single-family residences with a separate water meter or water charge may apply for an exemption from payment of the sewer service charge. Senior citizens age 65 and older living in condominiums are eligible to apply for an annual rebate of $50 on sewer service charges. For 2014, overall revenues from metered accounts were $228,181,936 and overall revenues from non-metered accounts were $99,599,101.

During 2014, residential accounts represented approximately 68.9 percent of Sewer System revenues and industrial and commercial accounts represented approximately 24.2 percent of such revenues. The remaining 6.9 percent of revenues were derived from governmental and not-for-profit organizations. During the same period, residential non-metered accounts were approximately 30 percent of Sewer System revenues and residential metered accounts were approximately 70 percent of such revenues. All industrial and commercial accounts are metered. There are no large industrial or commercial users that account for more than five percent of Sewer System revenues. The five largest accounts of the Sewer System are shown on the following table.

(1) Actual amounts billed during calendar year: differs from Sewer Fund Basic Financial Statements which include charges accrued for calendar year regardless of year in which billed.

Collections and Delinquencies
The Department of Finance follows the same collection strategy for collecting sewer accounts as it does for water accounts. Users receiving both water and sewer service from the City are sent a combined bill which details the charges for each service. Partial payments on the combined bill are allocated on a pro rata basis between the water and sewer charges. The Department of Finance bills large industrial accounts each month, with a few exceptions that are billed quarterly. Metered commercial and residential accounts are billed once every two months. Non-metered accounts are billed once every six months.




26

Payments on both metered and non-metered accounts are due 20 days from when bills are issued. A late payment penalty assessed at a monthly rate of one and one-fourth percent is imposed on all sewer charges in excess of $10.00 for which payment in full is not received within twenty-four calendar days from the date the bill was sent as shown by the records of the Department of Finance.
Delinquency notices, which were generated at an average rate of 16,346 per week in 2014, are sent to delinquent accounts when their balances are thirty days past due. A second delinquency notice is sent after sixty days. A third delinquency notice is sent after ninety days. After an active account reaches 210 days past due with a balance of greater than $300, the account is referred to an outside law firm for collections. Inactive accounts (those that do not currently have water service) that are 90 days past due with balances of $200 or greater are referred to an outside law firm for collections. The outside law firm may pursue collections by obtaining a judgment at the City of Chicago Department of Administrative Hearings, placing a lien on the property or by additional legal collection actions.

Additionally, the Department of Finance, through its collection system refers any account for water service shut-off to the Department of Water Management if the account is in arrears and in accordance with its policy. Due to the concern for public safety, the Department of Finance makes every effort to collect delinquent accounts prior to terminating water service. Other than by terminating water service, it is not possible to terminate use ofthe sewer system by an individual user. Further, by ordinance, when a property is transferred, a deed cannot be recorded with the Cook County Recorder of Deeds unless the Department of Finance certifies that all water and sewer service charges due and owing with respect to such property have been paid in full.
The amount of annual net sewer charges and cash collected from current and prior years' billings are included in the table below. During the five-year period ended December 31, 2014, total sewer charges collected averaged approximately 95.02 percent of aggregate net sewer charges.

Sewer System Revenues Not Connected to the State of Illinois

The State of Illinois is obligated to make payments to the City in instances where it is a user of the Sewer System, except in situations and to the extent that the applicable State of Illinois property qualifies for an exemption. The revenue from the State as user accounts for less than one percent (1%) of the Sewer System's annual operating revenues. No operating revenues from any users of the Sewer System flow through the State of Illinois. All such revenues are paid directly to the City.




27

Annual Budget Review and Implementation of Annual Budget

The Department's annual budget is developed and implemented as part of the City's annual budget and it is based upon an analysis of its historical Operation and Maintenance Costs. If projected Gross Revenues are not sufficient to satisfy the rate covenants contained in the ordinances authorizing the Bonds and Senior Lien Bonds and Second Lien Bonds, as determined by the City pursuant to its annual review of the Sewer System, the Department is required, after consultation with the Budget Director and, when appropriate, a qualified independent consulting engineer, to recommend appropriate action to the City Council to comply with the rate covenants. See "SECURITY FOR THE BONDS — Second Lien Rate Covenant." If necessary, proposed rate increases will be included in the Department's proposed annual budget.
Once the Department has prepared and finalized its proposed annual budget, the Budget Director considers the Department's proposed budget along with the proposed annual budgets recommended and submitted by all of the other departments and agencies whose budgets become part of the City's proposed annual budget. Following the Budget Director's approval, the budgets must be approved by the Mayor, the City Council's Committee on Budget and Governmental Operations and the City Council. After the City Council has approved the proposed annual budget as the City's annual appropriation ordinance, it is forwarded to the Mayor for approval.

Should the Mayor veto the approved annual appropriation ordinance, the City Council may override the veto with a two-thirds vote.
The City Council may also refuse to approve the Mayor's proposed annual budget. In such a case, the appropriate process for passage of the City budget may have to be judicially determined. By law, the City's budget must be approved by December 31 of the year preceding the budget year. The City's 2015 budget was approved by the City Council on November 19, 2014.

During each year, the City allocates certain funds to meet debt service requirements and central services and General Fund reimbursements. The Budget Director uses an allotment system to manage each department's expenditures against its respective annual appropriation. The Budget Director requires departments to submit quarterly allotment budgets which the Budget Director, in turn, monitors. Should any department's expenditures exceed its receipt of revenues, the Budget Director, through the quarterly budget allotment procedure, has the authority to institute economy measures against such department to ensure that its expenditures do not exceed or outpace its revenue collection. During 2014, there were no such restrictions in the Department's quarterly expenditures.
Historical and Projected Operations
Following are the Sewer Revenue Fund's Statements of Operations, including debt service requirements, as summarized from the audited financial statements of the Sewer Revenue Fund for the years ended December 31, 2010 through December 31, 2014, together with projected financial operations and projected debt service requirements for the years ending December 31, 2015 through December 31, 2017.
The Sewer Revenue Fund's operating revenues for 2014 increased by $42.4 million compared to prior year operating revenues. This increase of 15 percent is primarily due to an increase in water and sewer rates.
The Sewer Revenue Fund's operating expenses before depreciation and amortization for 2014 increased $9.9 million (9 percent) from the year ended 2013 due to an increase in repairs, maintenance and administrative and general expenses.

Operating revenues are projected to increase in 2015-2017 based on an increase in water and sewer rates, offset by decreases due to water conservation efforts. Projected Operating Expenses in 2015, 2016 and 2017 are reflective of expected 4% increase in expenses based on 2014 amounts. The revised amounts of projected operating expenses also reflect an increase in each year based on growth in indirect costs being charged to the Sewer Revenue Fund as reimbursements to the General Fund, including public safety departments. The methodology for charging these indirect costs to the Sewer Revenue Fund is consistent with generally accepted accounting principles. The Sewer Revenue Fund has historically been charged for indirect costs properly allocable to that Fund. The revised projections for increased indirect costs reflect an increase in those projected indirect costs. The projected operating expenses also include a separate line item for pension contributions. Starting in 2015, the pension contribution amounts allocable to the respective enterprise funds, including the Sewer Revenue Fund, are being contributed to the pension funds instead of reimbursing the General Fund. See "—Pension and Other Post-Employment Benefit Costs" herein. The General Fund reimbursement line item for 2015-2017 does not include the pension contribution.
Water usage in the City, upon which sewer charges are based, is assumed to decrease slightly throughout the projection period due to water conservation efforts. In addition to rate increases, the City could achieve compliance with its rate covenants in some other manner, including any combination of rate increases, decreases in operating expenses, changes in its capital improvement program or in the timing and amounts of future borrowings or changes in net transfers to or from the Sewer Rate Stabilization Account.
The City has prepared the projections discussed herein and summarized in the table below. The City believes that the underlying assumptions provide a reasonable basis for the projections, and that the projections present, to the best of the City's knowledge and belief, the City's expected course of action. However, some of the assumptions upon which the projections are based inevitably will not materialize and unanticipated events and circumstances may occur. The management of the City has prepared the projected financial information set forth below to present the expected financial performance of the Sewer System.
The accompanying projected financial information was not prepared with a view toward complying with the guidelines established by the American Institute of Certified Public Accountants with respect to projected financial information, but, in the view of the City's management, was prepared on a reasonable basis, reflects the best currently available estimates and judgments, and presents, to the best of management's knowledge and belief the expected course of action and the expected future financial performance of the Sewer System. Accordingly, these projections are not fact and should not be relied on as being necessarily indicative of future results, and readers of this Official Statement are cautioned not to place undue reliance on the projected operations of the Sewer System which are contained herein.
Neither the City's independent auditors, nor any other independent accountants, have compiled, examined, or performed any procedures with respect to the projected financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, the projected financial information.

Pension and Other Post-Employment Benefit Costs

The Department of Water Management treats the pension costs paid out of the Sewer Revenue Fund as Operation and Maintenance Costs for purposes of determining Net Revenues Available for Bonds and for the City's compliance with its covenants (including the Rate Covenant) under the Series 2015 Bond Ordinance and the Indenture. See "INTRODUCTION - Rate Covenant." The Department of Water Management expects to continue its current practice of treating pension costs as Operation and Maintenance Costs.

The City participates in four defined-benefit retirement funds (the "Retirement Funds"). Sewer System employees participate in one of two of these Retirement Funds: the Municipal Employees' Annuity and Benefit Fund of Chicago ("MEABF"), and the Laborers' and Retirement Board Employees' Annuity and Benefit Fund of Chicago ("LABF"). The City's annual contributions to these plans have been funded by a separate property tax levy with the remaining portion funded by the General Fund and the portion of the contribution allocable to the respective Enterprise Fund. The Sewer System, through the Sewer Revenue Fund, contributes the estimated pension cost applicable to the covered payroll of Sewer System employees to the respective Retirement Fund. These contributions are recorded as Operation and Maintenance Costs of the Sewer Revenue Fund. See APPENDIX A-"CITY OF CHICAGO, ILLINOIS SEWER FUND BASIC FINANCIAL STATEMENTS AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2014 AND 2013, STATISTICAL DATA, AND INDEPENDENT AUDITORS' REPORT-Notes to Basic Financial Statements - 6. Pension Plans." Pension liabilities are not recorded at the fund level for the Sewer Fund.

Both MEABF and LABF are significantly underfunded. In June 2014, the State enacted legislation, known as P.A. 98-641, that, among other things, required the City to significantly increase its payments to such Retirement Funds beginning in budget year 2015 (payment year 2016). P.A. 98-641 has been determined to be unconstitutional by the Cook County Circuit Court (the "Circuit Court"). The City has appealed the Circuit Court's decision to the Illinois Supreme Court. The City can give no assurance as to the ultimate outcome of this litigation. For 2015, the Department of Water Management budgeted $7.7 million in the Sewer Revenue Fund for contributions on behalf of Sewer System employees enrolled in MEABF and LABF. If the Illinois Supreme Court overturns the Circuit Court's ruling such that P.A. 98-641 is once again effective, the Sewer System's pension costs, based upon employees allocable to the Sewer System, would be expected to increase to approximately $8.8 million in budget year 2016 (paid in 2017) and to slightly more than $11.7 million in budget year 2017 (paid in 2018). Thereafter, the Sewer System's pension costs would be expected to increase by an annual average of approximately 21 percent until budget year 2019 (payment year 2020). Beginning in budget year 2020 (payment year 2021), the City's payments to MEABF and LABF (and the Sewer System's share thereof) would be based upon actuarial funding requirements under P.A. 98-641. If the Illinois Supreme Court upholds the Circuit Court's ruling, the manner of funding MEABF and LABF will continue to be made pursuant to the multiplier funding system. Notwithstanding the foregoing, the City reserves the right to change the amount it allocates to the Sewer Revenue Fund in any given year, for employee pension costs allocable to the Sewer Revenue Fund, at any time. For more information on P.A. 98-641 and the litigation related thereto, see APPENDIX E-"RETIREMENT FUNDS." Increased Sewer System operating revenues from scheduled sewer rate increases are expected to more than offset such increases in retirement costs allocable to the Sewer Revenue Fund. See "FINANCIAL OPERATIONS-Historical and Projected Operations."
As described in APPENDIX E-"RETIREMENT FUNDS-Payment for Other Post-Employment Benefits," the City and its retirement funds currently share the cost of post-employment healthcare benefits available to City employees participating in the retirement funds (the "Health Plan"). The costs of the Health Plan were previously shared pursuant to a settlement agreement between the City and its retirement funds regarding the responsibility for payment of these healthcare benefits. The settlement agreement expired on June 30, 2013, and the City intends to phase out health benefits for most retirees by 2017. In 2014, the Department of Water Management paid $1.3 million from the Sewer Revenue Fund for Health Plan costs allocable to retirees who are former Sewer System employees. For 2015, the Department of Water Management



32

budgeted $0.5 million for this payment. After expiration of the settlement, certain of the affected participants filed a lawsuit to reactivate the litigation covered by the settlement, which lawsuit remains pending. For further information on the status of the Health Plan after June 30, 2013, including certain State and federal litigation relating to the City's plans to phase out the Health Plan and the settlement agreement, see APPENDIX E-"RETIREMENT FUNDS-Payment for Other Post-Employment Benefits."

For additional information on the City's retirement funds, including MEABF and LABF, and the Health Plan, see APPENDIX E - "RETIREMENT FUNDS."

INVESTMENT CONSIDERATIONS
The following discussion of investment considerations should be reviewed by prospective investors prior to purchasing the Bonds. Any one or more of the investment considerations discussed herein could lead to a decrease in the market value and the liquidity of the Bonds or, ultimately, a payment default on the Bonds. There can be no assurance that other factors not discussed herein will not become material in the future.
Effect of Potential Future Ratings Downgrades
In May 2015, each of Moody's, S&P and Fitch lowered their respective ratings on the City's outstanding general obligation bonds. That same month, both Moody's and S&P lowered their ratings on the Outstanding Senior Lien Bonds and Outstanding Second Lien Bonds, while Fitch placed its ratings on the Outstanding Second Lien Bonds on negative watch. The City cannot predict if or when, or on what basis, the rating agencies may take further action with respect to such credit ratings, and no assurances can be provided that the City's credit ratings on its outstanding general obligation bonds, Senior Lien Bonds, or Second Lien Bonds will not be subject to further downgrades. Such rating downgrades with respect to the City's general obligation bonds may impact the City's interest costs and could make it more difficult or expensive for the City to find funding sources for its financing needs, resulting in the need for the City to increases taxes or implement cutbacks in City services or some combination thereof.
The City does not anticipate that any potential credit downgrades would impact collection or availability of Net Revenues Available for Bonds in any material respect. However, such events could have an adverse impact on the Sewer System because the City funds ongoing capital improvement projects to the Sewer System, in part, through the sale of indebtedness of the Sewer System. Downgrades could increase the cost, or decrease the availability, or both, of such borrowing. If this occurred, additional pressure may be placed on sewer rates or capital funding. Additionally, ratings downgrades may have an adverse effect on the price at which the Bonds may be resold in the future.

Unfunded Pensions
The City's four Retirement Funds, including LABF and MEABF, have significant unfunded liabilities and low funding ratios. Under current law, the City's required contributions to its police and fire pension funds will significantly increase beginning in 2016. The City has not identified the sources of funds to meet the City's pension obligations for its police and fire pension funds in 2016 or thereafter, and it is likely that, without further changes to the Pension Code, the City will have to seek increases in taxes or implement cutbacks in City services or some combination thereof to meet its obligations to such pension funds. If the City were to raise taxes substantially or reduce and/or eliminate essential city services, residents or businesses may choose to relocate to states or municipalities with a lower tax burden or better services. A drop in population could have an adverse impact on the amount of Net Revenues Available for Bonds if such events resulted in decreased use of the Sewer System.





33

Pension Reform Litigation
On July 24, 2015, the Circuit Court determined P.A. 98-641, the law which modified required contribution and benefit amounts for the MEABF and LABF, to be unconstitutional. The City has appealed the Circuit Court's decision to the Illinois Supreme Court.
If the Illinois Supreme Court upholds the Circuit Court's ruling with respect to the constitutionality of P.A. 98-641, the City's obligation to fund MEABF and LABF would revert to the prior, lower levels of funding based on the multiplier formula, which would have the effect of increasing the UAAL and decreasing the funded ratio of such Retirement Funds when compared to the law as modified by P.A. 98-641. The City makes no prediction as to whether the outcome of this litigation would have an effect on the amount of Net Revenues Available for Bonds received by the City. See APPENDIX E—"RETIREMENT FUNDS—Effect on MEABF and LABF if P.A. 98-641 Found Unconstitutional."

Environmental Regulations
The City is subject to state and federal environmental laws and regulations applicable to the Sewer System's overflows into Chicago area waterways. These laws and regulations are subject to change, and the City may be required to expend substantial funds to meet the requirements of such changing laws and regulations in the future. Failure to comply with these laws and regulations may result in the imposition of administrative, civil and criminal penalties, or the imposition of an injunction requiring the City to take or refrain from taking certain actions. In addition, the City may be required to remediate contamination on properties owned or operated by the City or on properties owned by others, but contaminated as a result of City operations.
Sewer services are governed by various federal and state environmental protection and health and safety laws and regulations, including the federal Clean Water Act and similar state laws, and federal and state regulations issued under these laws by the EPA and IEPA. These laws and regulations establish, among other things, criteria and standards for wastewater and for discharges into the waters of the United States and nearby states. Pursuant to these laws, the Department is required to obtain various environmental permits for operations. Violations or noncompliance could result in fines or other sanctions by regulators and/or such violations or noncompliance could result in civil suits. Environmental laws and regulations are complex and change frequently. These laws, and the enforcement thereof, have tended to become more stringent over time. While the Department has budgeted for future capital and operating expenditures to comply with these laws and permitting requirements, it is possible that new or stricter standards could be imposed that will require additional capital expenditures or raise operating costs.
Security of the Sewer System
Damage to the Sewer System resulting from vandalism, sabotage, or terrorist activities may adversely affect the operations and finances of the Sewer System. There can be no assurance that the City's security, emergency preparedness and response plans will be adequate to prevent or mitigate such damage, or that the costs of maintaining such security measures will not be greater than currently anticipated.
The Department relies on information technology systems with respect to customer service and billing and accounting. In addition, the Department relies on these systems to track utility assets and to manage maintenance and construction projects, materials and supplies. A loss of these systems, or major problems with the operation of these systems, could have a material adverse effect on the financial condition and results of operations of the Department. Information technology systems may be vulnerable to damage or interruption from the following types of cyber security attacks or other events:




34

power loss, computer systems failures, and internet, telecommunications or data network failures;
operator negligence or improper operation by, or supervision of, employees;
physical and electronic loss of data;
computer viruses, cyber security attacks, intentional security breaches, hacking, denial of service actions, misappropriation of data and similar events;
difficulties in the implementation of upgrades or modification to information technology systems; and
fires, floods, severe weather events and other natural disasters.
Although the Department does not believe that its systems are at a materially greater risk of cyber security attacks than other similar utilities, its information technology systems may be vulnerable to damage or interruption from the types of cyber security attacks or other events listed above or other similar actions, and such incidents or other events may go undetected for a period of time.
Water Conservation
Decreased customer water consumption as a result of water conservation efforts may adversely affect demand for sewer services and may reduce revenues and earnings. There may be declines in water usage per customer as a result of an increase in conservation awareness, and the structural impact of an increased use of more efficient plumbing fixtures and appliances. Difficulty obtaining future rate increases to offset decreased customer water consumption to cover investments and expenses, may adversely affect the business, financial condition, and results of operations of the Department.
Adverse Change in Laws
There are a variety of State and federal laws, regulations and constitutional provisions that apply to the City's ability to raise taxes, fund its pension obligations or to reorganize its debts. There is no assurance that there will not be any change in, interpretation of, or addition to such applicable laws, regulations and provisions. Any such change, interpretation or addition may have a material adverse effect, either directly or indirectly, on the City or the taxing authority of the City, which could materially adversely affect the City's operations or financial condition.
Bankruptcy

Municipalities cannot file for protection under the U.S. Bankruptcy Code unless specifically authorized to be a debtor by state law. Illinois law does not currently provide such authorization for municipalities; however, legislation was recently introduced into the General Assembly of the State which, if enacted, would permit Illinois municipalities to file for bankruptcy under the U.S. Bankruptcy Code. No assurance can be provided as to whether any such legislation that would permit municipalities such as the City to file for bankruptcy will be enacted into law. In the event of a change in State law allowing the City to file for bankruptcy protection under the U.S. Bankruptcy Code, that does not mean that the City would file for protection under the U.S. Bankruptcy Code.
In the event that a change in State law were to allow the City to file for protection under the U.S. Bankruptcy Code and the City were to file for such protection. Second Lien Bond Revenues and amounts on deposit in Second Lien Construction Accounts would continue to be subject to the pledge under the Indenture and the City would endeavor to continue to deposit Gross Revenues into the Sewer Revenue Fund so that Gross



35

Revenues would continue to be deposited into the Sewer Revenue Fund and Gross Revenues would continue to be disbursed to the Accounts within the Sewer Revenue Fund in accordance with the Series 2015 Ordinance. While the Sewer Revenue Fund is an enterprise fund separate from the general operating fund of the City, there is some likelihood that Gross Revenues would not be considered trust funds for the period of time from their receipt by the City until they are deposited in the Bond Principal and Interest Account or the Second Lien Bonds Account. Prior to the deposit of Gross Revenues in the Second Lien Bonds Account, a bankruptcy trustee may be able to intercept Gross Revenues and materially impair the City's ability to pay debt service on the Bonds when due.
Uncertain Enforcement Remedies
The remedies available to bondholders upon nonpayment of principal of or interest on the Bonds are uncertain and in many respects dependent upon discretionary judicial actions. See APPENDIX C— "SUMMARY OF CERTAIN PROVISIONS OF THE INDENTURE—Remedies."

Force Majeure Events
There are certain unanticipated events beyond the City's control that could have a material adverse impact on the Department's and City's operations and financial conditions 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, terrorism or enemy action, pollution, unknown subsurface or 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 ofthe impact on the Department's and City's operations and financial condition or of the impact on the Net Revenues Available for Bonds.
Other Considerations
Debt Covenants. The City is obligated to comply with the rate covenant. Failure to comply with such covenant, if not cured or waived, could result in the City being required to repay or finance the related borrowings before their due date, limit future borrowings, cause cross default issues, and increase borrowing costs. If forced to repay or refinance (on less favorable terms) these borrowings, the Department's business, financial condition, and results of operations could be adversely affected by increased costs and rates.
Sewer Rates. While there is currently no State statute regulating Sewer rates, future State statutes or court decisions could limit or otherwise adversely affect the City's ability to set sewer rates.
Potential Garbage Collection Fee and Combined Billing. The City is considering a proposal to impose a fee for the collection of garbage by the City from households in the City. Such a fee may be imposed through a combined bill which would also include the collection of water and sewer charges by the City for such households. As described above under "FINANCIAL OPERATIONS—Collections and Delinquencies," sewer and water charges currently appear on a combined bill to users, and any partial payments are allocated pro rata between the water and sewer charges. It is expected that if the garbage fee is imposed and included on the combined bill, partial bill payments would be allocated first between the water charges and the sewer charges on a pro rata basis, and then to the garbage fee. No assurance can be given, however, that this will be the method of allocation of partial payments if the proposal is enacted by the City. It is possible that partial payments may be allocated in a non-pro rata manner among the garbage collection fee, the water charges, and the sewer charges, with the result that one charge may be paid after others. In that event, sewer charges could receive a lower priority than garbage fees and/or water fees in allocating partial payments. Further, regardless of which method is first included in an enacted proposal, the City may also later change the method of allocating partial



36

payments of a combined bill. If a garbage fee proposal were to be enacted with a combined bill for water and sewer charges (regardless of the method for allocating partial payments among the different charges), no assurance can be given as to the impact of such proposal on the collection by the C ity of sewer charges.
Sewer PILOT. A payment in lieu of taxes ("PILOT") by the Sewer Revenue Fund to the City's General Fund is not currently included in the flow of funds from the Sewer Revenue Fund as prescribed by the ordinances authorizing Senior Lien Bonds and Second Lien Bonds. If the City were to consider implementing such a payment, the City expects that all outstanding debt payable from Sewer System revenues would first be paid or defeased before a PILOT was established.
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 actual 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. 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.
LITIGATION
There are no pending legal proceedings to which the City is a party or to which any of its property is subject that may materially affect the City's ability to pay the principal of and interest on the Bonds when they become due.
The City, like other large municipalities, is involved in various litigation relating principally to claims arising from contracts, personal injury, property damage, tax claims, police conduct and other matters. However, there is neither litigation pending nor, to the best of the City's knowledge, threatened, seeking to restrain or enjoin the issuance or delivery of the Bonds, or except as disclosed herein, materially adversely affecting the collection, pledge or application of any moneys or security provided for the payment of the Bonds.

RATINGS
The Bonds are rated "A" (stable outlook) by S&P, "AA" (negative outlook) by Fitch Ratings, Inc., and "AA-" (stable outlook) by Kroll Bond Rating Agency, Inc. The City did not request a rating from any other rating service for the Bonds. Any explanation of the significance of such ratings may be obtained only from the respective Rating Agencies. Certain information and materials concerning the Bonds, the City and the Sewer System were furnished to the Rating Agencies by the City and others. There is no assurance that any of the ratings will be maintained for any given period of time or that any of them may not be raised, lowered or withdrawn entirely by the respective Rating Agency, if, in its judgment, circumstances so warrant. Any change in or withdrawal of any rating may have an adverse effect on the price at which the Bonds may be resold.
CERTAIN TAX CONSIDERATIONS
General
Interest on the Bonds is not excluded from gross income for federal income tax purposes under Section 103 of the Internal Revenue Code of 1986, as amended (the "Code").



37

The following is a summary of certain material federal income tax consequences of holding and disposing of the Bonds. This summary is based upon laws, regulations, rulings and judicial decisions now in effect. Legislative, judicial and administrative changes may occur, possibly with retroactive effect, that could alter or modify the continued validity of the statements and conclusions set forth in this section. This summary does not discuss all aspects of federal income taxation that may be relevant to investors. This summary is intended as a general explanatory discussion of the consequences of holding and disposing of the Bonds and does not purport to furnish information in the level of detail or with the investor's specific tax circumstances that would be provided by an investor's own tax advisor. For example, except as explicitly provided below, it generally is addressed only to original purchasers of the Bonds, deals only with Bonds held as capital assets within the meaning of Section 1221 of the Code and does not address tax consequences to holders subject to special rules, such as tax-exempt investors, dealers in securities, currencies or commodities, banks, thrifts, insurance companies, electing large partnerships, mutual funds, regulated investment companies, real estate investment trusts, S corporations, persons that hold Bonds as part of a straddle, hedge, integrated or conversion transaction, and persons whose "functional currency" is not the U.S. dollar. In addition, this summary does not address alternative minimum tax issues or the indirect consequences to a holder of an equity interest in a holder of Bonds. This summary was prepared in connection with the offering of the Bonds. Each prospective investor should consult with its own tax advisor regarding the application of United States federal income tax laws, as well as any state, local, foreign or other tax laws, to such investor's particular situation.
As used in this section, a "U.S. Holder" is a "U.S. person" that is a beneficial owner of a Bond. A "Non-U.S. Holder" is a holder (or beneficial owner) of a Bond that is not a U.S. person. For these purposes, a "U.S. person" is a citizen or resident ofthe United States, a corporation or partnership created or organized in or under the laws of the United States or any of its political subdivisions (except, in the case of a partnership, to the extent otherwise provided in Treasury regulations), an estate the income of which is subject to United States federal income taxation regardless of its source or a trust if (i) a United States court is able to exercise primary supervision over the trust's administration and (ii) one or more United States persons have the authority to control all of the trust's substantial decisions.
Tax Status ofthe Bonds
The Bonds will be treated, for federal income tax purposes, as a debt instrument. Accordingly, interest will be included in the income of the holder as it is paid (or, if the holder is an accrual method taxpayer, as it is accrued) as interest.
The City anticipates that the Bonds will not be treated as issued with original issue discount ("OID") for federal income tax purposes because the stated redemption price at maturity will not exceed their issue price or because any such excess will be treated as de minimis under the OID rules. If the excess of the stated redemption price at maturity of a Bond over its "issue price" exceeds a specified de minimis amount (generally equal to 0.25% of the stated redemption price at maturity multiplied by the number of complete years to maturity), the excess will be treated as OID. The issue price of the Bonds is the first price at which a substantial amount of the Bonds is sold to the public.
With respect to a U.S. Holder that purchases in the initial offering a Bond issued with OID, the amount of OID that accrues during any accrual period equals (i) the "adjusted issue price" of the Bond at the beginning of the accrual period (which price equals the issue price of such Bond plus the amount of OID that has accrued on a constant-yield basis in all prior accrual periods minus the amount of any payments, other than "qualified stated interest," received on the Bond in prior accrual periods) multiplied by (ii)the yield to maturity of such Bond (determined on the basis of compounding at the close of each accrual period and properly adjusted for the length of each accrual period) less (iii) any qualified stated interest payable on the Bond during such accrual period. The amount of OID so accrued in a particular accrual period will be considered to be received ratably on each day of the accrual period.

A U.S. Holder of a Bond issued with OID must include in gross income for federal income tax purposes the amount of OID accrued with respect to each day during the taxable year that the U.S. Holder owns the Bond. Such an inclusion in advance of receipt of the cash attributable to the income is required even if the U.S. Holder is on the cash method of accounting for United States federal income tax purposes. The amount of OID that is includible in a U.S. Holder's gross income will increase the U.S. Holder's tax basis in the Bond. The adjusted tax basis in a Bond will be used to determine taxable gain or loss upon a disposition (for example, upon a sale or retirement) of the Bond.
Holders ofthe Bonds with a basis in the Bonds that is greater than the principal amount of the Bonds should consult their own tax advisors with respect to whether or not they should elect to amortize such premium under Section 171 ofthe Code.
If a holder purchases the Bonds after the initial offering for an amount that is less than the principal amount of the Bonds, and such difference is not considered to be de minimis, then such discount will represent market discount that ultimately will constitute ordinary income (and not capital gain). Absent an election to accrue market discount currently, upon a sale or exchange of a Bond, a portion of any gain will be ordinary income to the extent it represents the amount of any such market discount that was accrued through the date of sale. In addition, absent an election to accrue market discount currently, the portion of any interest expense incurred or continued to carry a market discount Bond that does not exceed the accrued market discount for any taxable year will be deferred.

Medicare Tax
An additional 3.8% tax will be imposed on the net investment income (which includes interest, original issue discount and gains from a disposition of a Bond) of certain individuals, trusts and estates. Prospective investors in the Bonds should consult their tax advisors regarding the possible applicability of this tax to an investment in the Bonds.
Sale and Exchange of Bonds

Upon a sale or exchange of a Bond, a holder generally will recognize gain or loss on the Bonds equal to the difference between the amount realized on the sale and its adjusted tax basis in such Bond. Such gain or loss generally will be capital gain (although any gain attributable to accrued market discount of the Bond not yet taken into income will be ordinary) if the holder holds the Bond as a capital asset. The adjusted basis of the holder in a Bond (without OID) generally will equal its original purchase price decreased by any principal payments received on the Bond. If the Bond is held for longer than one year, any gain or loss generally would be long term capital gain or loss. Capital losses are subject to certain limitations.
If the liability of the City in respect of a Bond ceases as a result of an election by the City to pay and discharge the indebtedness on such Bond by depositing with the Trustee sufficient cash and/or Government Obligations to pay or redeem and discharge the indebtedness on such Bond (a "legal defeasance"), under current tax law a holder will be deemed to have sold or exchanged such Bond. In the event of such a legal defeasance, a holder generally will recognize gain or loss on the deemed exchange of the Bonds. Ownership of the Bonds after a deemed sale or exchange as a result of a legal defeasance may have tax consequences different than those described in this section and each holder should consult its own tax advisor regarding the consequences to such holder of a legal defeasance of the Bonds.

Backup Withholding

The Trustee (the "payor") must report annually to the Internal Revenue Service (the "IRS") and to each U.S. Holder any interest that is payable to the U.S. Holder, subject to certain exceptions. Under Section 3406 of



39

the Code and applicable Treasury Regulations, a non-corporate U.S. Holder of the Bonds may be subject to backup withholding at the current rate of 28% (subject to future adjustment) with respect to "reportable payments," which include interest paid on the Bonds and the gross proceeds of a sale, exchange, redemption or retirement of the Bonds. The payor will be required to deduct and withhold the prescribed amounts if (i) the payee fails to furnish a taxpayer identification number ("TIN") to the payor in the manner required, (ii) the IRS notifies the payor that the TIN furnished by the payee is incorrect, (iii) there has been a "notified payee underreporting" described in Section 3406(c) of the Code or (iv) there has been a failure of the payee to certify under penalty of perjury that the payee is not subject to withholding under Section 3406(a)(1)(C) of the Code. Amounts paid as back-up withholding do not constitute an additional tax and will be credited against the U.S. Holder's federal income tax liabilities (and possibly result in a refund), so long as the required information is timely provided to the IRS.
Certain U.S. Federal Income Tax Consequences to Non-U.S. Holders
This section describes certain U.S. federal income tax consequences to Non-U.S. Holders.
If, under the Code, interest on the Bonds is "effectively connected with the conduct of a trade or business within the United States" by a Non-U.S. Holder, such interest will be subject to U.S. federal income tax in a similar manner as if the Bonds were held by a U.S. Holder, as described above, and in the case of Non-U.S. Holders that are corporations may be subject to U.S. branch profits tax at a rate of up to 30%, unless an applicable tax treaty provides otherwise. Such Non-U.S. Holder will not be subject to withholding taxes, however, if it provides a properly executed Form W-8ECI to the payor.
Interest on the Bonds held by other Non-U.S. Holders may be subject to withholding taxes of up to 30% of each payment made to the Non-U.S. Holders unless the "portfolio interest" exemption applies. In general, interest paid on the Bonds to a Non-U.S. Holder will qualify for the portfolio interest exemption, and thus will not be subject to U.S. federal withholding tax, if (l)such Non-U.S. Holder is not a "controlled foreign corporation" (within the meaning of Section 957 of the Code) related, directly or indirectly, to the City or a bank and the payor receives a certification of such facts from the Non-U.S. Holder; and (2) the payor receives from the Non-U.S. Holder who is the beneficial owner of the obligation a statement signed by such person under penalties of perjury, on IRS Form W-8BEN or IRS Form W-8BEN-E (or successor form), certifying that such owner is not a U.S. Holder and providing such owner's name and address. Alternative methods may be applicable for satisfying the certification requirement described above. Foreign trusts and their beneficiaries are subject to special rules, and such persons should consult their own tax advisors regarding the certification requirements.
If a Non-U.S. Holder does not claim, or does not qualify for, the benefit of the portfolio interest exemption, the Non-U.S. Holder may be subject to a 30% withholding tax on interest payments on the Bonds. However, the Non-U.S. Holder may be able to claim the benefit of a reduced withholding tax rate under an applicable income tax treaty between the Non-U.S. Holder's country of residence and the U.S. Non-U.S. Holders are urged to consult their own tax advisors regarding their eligibility for treaty benefits. The required information for claiming treaty benefits is generally submitted on Form W-8BEN or IRS Form W-8BEN-E. In addition, a Non-U.S. Holder may under certain circumstances be required to obtain a U.S. taxpayer identification number.
A Non-U.S. Holder will generally not be subject to U.S. federal income tax or withholding tax on gain recognized on a sale, exchange, redemption or other disposition of a Bond. (Such gain does not include proceeds attributable to accrued but unpaid interest on the Bonds, or accrued OID not previously taken into account, which will be treated as interest.) A Non-U.S. Holder may, however, be subject to U.S. federal income tax on such gain if: (l)the Non-U.S. Holder is a nonresident alien individual who was present in the United States for 183 days or more in the taxable year of the disposition, or (2) the gain is effectively connected with



40

the conduct of a U.S. trade of business, as provided by applicable U.S. tax rules (in which case the U.S. branch profits tax may also apply), unless an applicable tax treaty provides otherwise.
The payor must report annually to the IRS and to each Non-U.S. Holder any interest that is subject to U.S. withholding taxes or that is exempt from U.S. withholding taxes pursuant to an income tax treaty or certain provisions ofthe Code. Copies of these information returns may also be made available under the provisions of a specific tax treaty or agreement with the tax authorities of the country in which the Non-U.S. Holder resides.

Payments to Non-U.S. Holders will be net of any applicable withholding tax. The City is not providing any indemnification or gross-up in regard to such taxes.
A Non-U.S. Holder generally will not be subject to backup withholding with respect to payments of interest on the Bonds as long as the Non-U.S. Holder (i) has furnished to the payor a valid IRS Form W-8BEN or IRS Form W-8BEN-E certifying, under penalties of perjury, its status as a non-U.S. person, (ii) has furnished to the payor other documentation upon which it may rely to treat the payments as made to a non-U.S. person in accordance with Treasury regulations, or (iii) otherwise establishes an exemption. A Non-U.S. Holder may be subject to information reporting and/or backup withholding on a sale of the Bonds through the United States office of a broker and may be subject to information reporting (but generally not backup withholding) on a sale of the Bonds through a foreign office of a broker that has certain connections to the United States, unless the Non-U.S. Holder provides the certification described above or otherwise establishes an exemption. Non-U.S. Holders should consult their own tax advisors regarding their qualification for exemption from backup withholding and the procedure for obtaining such an exemption.
Amounts withheld under the backup withholding rules may be refunded or credited against the Non-U.S. Holder's U.S. federal income tax liability, if any, provided that the required information is timely furnished to the IRS.

In addition to the rules described above concerning the potential imposition of withholding on interest payments to Non-U.S. Holders, payments of interest after June 30, 2014, to Non-U.S. Holders that are "financial institutions" may be subject to a withholding tax of 30% unless an agreement is in place between the financial institution and the U.S. Treasury to collect and disclose information about accounts, equity investments, or debt interests in the financial institution held by one or more U.S. persons or the financial institution is a resident in a jurisdiction that has entered into such an agreement. For these purpose, a "financial institution" means any entity that (i) accepts deposits in the ordinary course of a banking or similar business, (ii) holds financial assets for the account of others as a substantial portion of its business, or (iii) is engaged (or holds itself out as being engaged) primarily in the business of investing, reinvesting or trading in securities, partnership interests, commodities or any interest (including a futures contract or option) in such securities, partnership interests or commodities.

Payments of interest to non-financial non-U.S. entities (other than publicly traded foreign entities, entities owned by residents of U.S. possessions, foreign governments, international organizations, or foreign central banks), will also be subject to a withholding tax of 30% if the entity does not certify that the entity does not have any substantial U.S. owners or provide the name, address and TIN of each substantial U.S. owner.
If a Non-U.S. Holder would be subject to the withholding on payments of interest described in the two preceding paragraphs, the gross proceeds from a disposition of a Bond may also be subject to a withholding tax of 30% after December 31, 2016.

During the period from 1996 through 2007, the City issued multiple series of Collateralized Single Family Mortgage Revenue Bonds (the "Single Family Bonds"). The trustees for the respective series of the Single Family Bonds are responsible for continuing disclosure filings as the City's dissemination agent under the applicable continuing disclosure undertakings. No annual reports were filed in the following years for the following series: 2004 (2002C and 2002D), 2006 (2000C), 2007 (2006K, 2007A and 2007B), and 2008 (2000C). During the period 2005-2009, annual reports were filed late for one or more years for the following series: 1996A, 1996B, 1997A, 1997B, I998AI, 1998C, 1999A, 1999C, 2000A, 2000C, 2001 A, 2001C, 2002A, 2002B, 2002C, 2006A, 2006B, 2006C, 2006D, 2006E, 2006F, 2006G, 2006H, 20061, 2006J, 2007-2A, 2007-2B, 2007-2G and 2007-2H.

With respect to the City's Residual Revenue Capital Appreciation Bonds, Series 2003 (the "Residual Revenue Bonds"), which were payable solely from residual revenues available under the indentures for the Single Family Bonds, Series 1996 through 1999, after payment in full of such bonds, no annual reports were filed by the trustee as the City's dissemination agent with respect to the Residual Revenue Bonds. Redemption notices for the Residual Revenue Bonds were filed by the trustee for January and February 2010, with the Residual Revenue Bonds being fully redeemed in February 2010.





46

No annual reports were filed by the City in 2008 with respect to three subseries of its General Obligation Direct Access Bonds. No annual report was filed by the City in 2010 with respect to one subseries of such bonds. A material event notice regarding the downgrade of the rating on the City's general obligation bonds by Fitch on October 12, 2009 was not filed for one subseries of such bonds.
Annual reports were not filed by the City in 2010 with respect to one series of the City's Chicago O'Hare International Airport General Airport Revenue Bonds and one series of its Chicago O'Hare International Airport Passenger Facility Charge Revenue Bonds.

With respect to the City's Collateralized Single Family Mortgage Revenue Bonds, Series 2006A (the "Series 2006A Bonds"), S&P lowered its rating on the Series 2006A Bonds from "AA+" to "AA" and placed the Series 2006A Bonds on "Credit Watch with negative implications" effective December 16, 2011. The City did not cause the trustee as dissemination agent to file a notice of a reportable event with EMMA at that time. Subsequently, S&P upgraded the rating on the Series 2006A Bonds from "AA" to "AA+" effective March 12,2012. On March 18, 2012, S&P removed the "Credit Watch with negative implications" characterization from the Series 2006A Bonds. The City caused the trustee, as dissemination agent, for the Series 2006A Bonds to file a notice of a reportable event with EMMA on March 26, 2012 disclosing the downgrade and subsequent upgrade of the Series 2006A Bonds by S&P.
With respect to the City's Chicago O'Hare International Airport General Airport Third Lien Revenue Bonds, Series 2011, American Airlines is an "obligated person" with respect to such bonds. On November 29, 2011, AMR Corporation (the parent company of American Airlines and American Eagle) and certain of its United States-based subsidiaries (including American Airlines and American Eagle) filed voluntary petitions for Chapter 11 reorganization in the United States Bankruptcy Court for the Southern District of New York.

The Rating Agencies took certain rating actions with respect to the ratings of Ambac Assurance Corporation and Financial Security Assurance Inc. (collectively, the "Bond Insurers"). The Bond Insurers provided municipal bond insurance policies relating to certain series of the City's Chicago Midway Airport revenue bonds.

Management's Responsibility for the Basic Financial Statements
Management is responsible for the preparation and fair presentation of these basic 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 basic 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 basic 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 significant accounting estimates made by management, as well as evaluating the overall presentation of the basic financial statements.
Wc believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

The statements of net position present all of the Sewer Fund's assets, deferred outflows, and liabilities using the accrual basis of accounting. The difference between assets, deferred outflows, and liabilities is reported as net position. The increase or decrease in net position may serve as an indicator, over time, whether the Sewer Fund's financial position is improving or deteriorating. However, the consideration of other nonfinancial factors may be necessary in the assessment of overall financial position and health ofthe Sewer Fund.
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 Sewer Fund's operating, capital financing, and investing activities. These statements are prepared on a cash basis and 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 for a full understanding of the information provided in the basic financial statements.

CITY OF CHICAGO, ILLINOIS SEWER FUND

NOTES TO BASIC FINANCIAL STATEMENTS
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2014 AND 2013
(In thousands)


1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Organization—The Sewer Fund (the "Sewer Fund") collects and transmits wastewater to the treatment facilities of the Metropolitan Water Reclamation District of Greater Chicago. The Sewer Fund is included in the City of Chicago, Illinois (the "City"), reporting entity as an enterprise fund.
The accompanying basic financial statements present only the Sewer Fund and are not intended to present the financial position of the City or the results of its operations and cash flows.
Basis of Accounting—The accounting policies of the Sewer Fund are based upon accounting principles generally accepted in the United States of America as prescribed by the Governmental Accounting Standards Board (GASB). The accounting and financial reporting treatment applied to a fund is determined by its measurement focus. The accounts of the Sewer Fund are reported using the flow of economic resources measurement focus.
The Sewer Fund uses the accrual basis of accounting under which revenues arc recognized when earned and expenses are recognized when the liability is incurred.
When both restricted and unrestricted resources are available for use, it is the City's policy to use restricted resources first, then unrestricted resources as they are needed.

Annual Appropriated Budget—The Sewer Fund has a legally adopted annual budget that is not required to be reported.

Management's Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash, Cash Equivalents, and Investments—Cash, cash equivalents, and investments generally are held with the City Treasurer as required by the Municipal Code of Chicago (the "Code"). Interest earned on pooled investments is allocated to participating funds based upon their average combined cash and investment balances. Due to contractual agreements or legal restrictions, the cash and investments of certain funds are segregated and earn and receive interest directly.

The Code permits deposits only to City Council-approved depositories, which must be organized state or national banks and federal and state savings and loan associations, located within the City, whose deposits are federally insured.
Investments authorized by the Code include interest-bearing general obligations of the City, the State of Illinois (the "State"), and the U.S. government; U.S. Treasury bills and other non-intcrest-bearing general obligations ofthe U.S. government purchased in the open market below face value; domestic


- 15-

money market funds regulated by and in good standing with the Securities and Exchange Commission; and tax anticipation warrants issued by the City. The City is prohibited by ordinance from investing in derivatives, as defined, without City Council approval.
The Sewer Fund values its investments at fair value or amortized cost, as applicable. U.S. government securities purchased at a price other than par with a maturity of less than one year are reported at amortized cost. The fair value of U.S. agency securities, corporate bonds, and municipal bonds are estimated using recently executed transactions, market price quotations (where observable), or bond spreads.
Repurchase agreements can be purchased only from banks and certain other institutions authorized to do business in the State. The City Treasurer requires that securities pledged to secure these agreements have a market value equal to the cost ofthe repurchase agreement, plus accrued interest.
Investments, generally, may not have a maturity in excess of 10 years from the date of purchase. Certain other investment balances are held in accordance with the specific provisions of applicable bond ordinances.
Cash equivalents include certificates of deposit and other investments with maturities of three months or less when purchased.

Accounts Receivable—The Sewer Fund accounts receivable result from billings and collections for sewer services processed by the Department of Water Management. Management has provided an allowance for amounts recorded at year-end that may be uncollectible.
Transactions with the City—The City's General Fund provides services to all other funds. The amounts allocated to other funds for these services are treated as operating expenses by the Sewer Fund and consist mainly of employee benefits, self-insured risks, and administrative expenses.
Inventories—Inventories, composed mainly of materials and supplies, are stated at cost, determined principally on the first-in, first-out method.

Utility Plant—Utility plant is recorded at cost or, for donated assets, at fair value at the date of acquisition. Utility plant is defined by the Sewer Fund as assets with an initial cost of more than $5,000 and an estimated useful life in excess of two years. Such assets are recorded at historical cost if purchased. Depreciation is provided using the straight-line method and begins in the year following the year of acquisition or completion. Estimated useful lives are as follows:
Facilities and structures 75 years
Furniture and equipment 5-20 years
Sewer rehabilitation 50 years

Costs of repairs and maintenance that do not significantly extend the useful life of assets are charged to operations.
Deferred Outflows—Deferred outflows represent the fair value of derivative instruments that are deemed to be effective hedges and unamortized loss on bond refundings.

Net Position—Net position is composed of net earnings from operating and nonoperating revenues, expenses, and capital grants. Net position is displayed in three components: net investment in capital assets, restricted for capital projects, and unrestricted. Net investment in capital assets consists of all


- 16-

capital assets, net of accumulated depreciation and reduced by outstanding debt, net of debt service reserve, and unspent bond proceeds. Restricted for capital projects consists of assets on which constraints are placed by external parties (such as lenders and grantors) and laws, regulations, and enabling legislation, reduced by liabilities and deferred inflows of resources related to those assets. Unrestricted consists of the net amount of all other assets, deferred outflows, liabilities, and deferred inflows not categorized as either of the above.
Employee Benefits—Employee benefits are granted for vacation and sick leave, workers' compensation, and health care. Unused vacation leave is accrued and may be carried over for one year. Sick leave is accumulated at the rate of one day for each month worked, up to a maximum of 200 days. Severance of employment terminates all rights to receive compensation for any unused sick leave. Sick leave pay is not accrued. Employee benefit claims outstanding, including claims incurred but not reported, are estimated and recorded as liabilities.
Employees are eligible to defer a portion of their salaries until future years under the City's deferred compensation plan created in accordance with Internal Revenue Code Section 457. The deferred compensation is not available to employees until termination, retirement, death, or unforeseeable emergency. The plan is administered by third-party administrators who maintain the investment portfolio. The plan's assets have been placed in trust accounts with the plan administrators for the exclusive benefit of participants and their beneficiaries and are not considered assets of the City.
The City is subject to the State Unemployment Compensation Act and has elected the reimbursing employer option for providing unemployment insurance benefits for eligible former employees. Under this option, the City reimburses the State for claims paid by the State.
Bond Issuance Costs, Bond Premiums Discounts, and Refunding Transactions—Bond issuance costs related to bond insurance and bond premiums discounts are deferred and amortized over the term of the related debt, except in the case of refunding debt transactions where the amortization period is over the term ofthe refunding or refunded debt, whichever is shorter.
Derivatives—The Sewer Fund enters into interest rate swap agreements to hedge interest rates and cash flows on outstanding debt. For existing swaps, the net interest expenditures resulting from these arrangements are recorded as interest expense. The fair value of derivative instruments that are deemed to be effective is accounted for as deferred outflows. Derivative instruments that are deemed not effective arc adjusted to fair value with the change in fair value recorded to investment earnings. All interest rate swaps are approved by City Council.
Capitalized Interest—Interest expense is capitalized during construction of those capital projects that are paid for from the bond proceeds and are being amortized over the depreciable life of the related assets on a straight-line basis. Interest expense capitalized for 2014 and 2013 totaled $4.4 million and $6.7 million, respectively.

Capital Grants—Capital grants are reported as contributed revenue in the statements of revenues, expenses, and changes in net position.
Revenue Recognition—Sewer service revenue is billed as a percentage of the City's water billings and is recorded as revenue when the water is consumed by the customers. Of the accounts receivable balances, $31.5 million and $26.8 million represent revenue recognized on sewer service that had not yet been billed to customers at December 31, 2014 and 2013, respectively. Unearned revenue represents amounts collected from nonmetered customers prior to usage.



- 17-

Revenues and Expenses—The Sewer Fund distinguishes operating revenues and expenses from nonoperating items. Operating revenues and expenses generally result from providing services and producing and delivering goods in connection with the Sewer Fund's principal ongoing operations. The principal operating revenues ofthe Sewer Fund are charges to customers for sales and services. Operating expenses include the cost of sales and services, administrative expenses, and depreciation and amortization on capital assets. All revenues and expenses not meeting this definition arc reported as nonoperating revenues and expenses.
Adopted Accounting Standards—GASB Statement No. 69, Government Combinations and Disposals of Government Operations ("GASB 69"), establishes accounting and financial reporting standards . related to government combinations and disposals of government operations. GASB 69 became effective for the Sewer Fund beginning with its year ended December 31, 2014. GASB 69 requires disclosures to be made about government combinations and disposals of government operations to enable financial statement users to evaluate the nature and financial effects of those transactions. There was no impact to the Sewer Fund's financial statements as a result of the implementation of GASB 69.
GASB Statement No. 70, Accounting and Financial Reporting for Nonexchange Financial Guarantees ("GASB 70"), establishes accounting and financial reporting standards for financial guarantees that arc nonexchange transactions (nonexchange financial guarantees) extended or received by a state or local government. GASB 70 became effective for the Sewer Fund beginning with its year ended December 31, 2014. GASB 70 requires a government that has issued an obligation guaranteed in a nonexchange transaction to report the obligation until legally released as an obligor. This statement also requires a government that is required to repay a guarantor for making a payment on a guaranteed obligation or legally assuming the guaranteed obligation to continue to recognize a liability until legally released as an obligor. When a government is released as an obligor, the government should recognize revenue as a result of being relieved ofthe obligation. This statement also provides additional guidance for intra-entity nonexchange financial guarantees involving blended component units. Requires disclosures to be made about government combinations and disposals of government operations to enable financial statement users to evaluate the nature and financial effects of those transactions. There was no impact to the Sewer Fund's financial statements as a result ofthe implementation of GASB 69.
Upcoming Accounting Standards—Other accounting standards that the Sewer Fund is currently reviewing for applicability and potential impact on the financial statements include:
GASB Statement No. 68, Accounting and Financial Reporting for Pensions ("GASB 68"), establishes new financial reporting requirements for most governments that provide their employees with pension benefits through these types of plans. GASB 68 will be effective for the Sewer Fund beginning with its year ending December 31, 2015. GASB 68 replaces the requirements of GASB Statement No. 27, Accounting for Pensions by State and Local Governmental Employers and GASB Statement No. 50, Pension Disclosures, as they relate to governments that provide pensions through pension plans administered as trusts or similar arrangements that meet certain criteria. GASB 68 requires governments providing defined benefit pensions to recognize their net liability for pension benefits, measured as the difference between total pension assets and total pension liability, as a liability in the financial statements that follow accrual basis of accounting for the first time, and to more comprehensively and comparably measure the annual costs of pension benefits. The statement also enhances accountability and transparency through revised and new note disclosures and required supplementary information (RSI). As of December 31, 2014, the City reported a net pension obligation of $8.6 billion on the statement of net position and disclosed a combined unfunded actuarial accrued liability for all of the pension plans of $19.7 billion in accordance with GASB Statement No. 27. During 2014, the pension plans implemented GASB Statement No. 67, Financial Reporting for Pension Plans—an amendment of GASB Statement No. 25, and disclosed a combined net pension liability of $20.1 billion as of



- 18-

December 31, 2014. The City has not yet determined the impact, if any, GASB 68 will have on the standalone Sewer Fund financial statements.
GASB Statement No. 71, Pension Transition for Contributions Made Subsequent to the Measurement Date—an amendment of GASB Statement No. 68 ("GASB 71"), relates to amounts associated with contributions, if any, made by a state or local government employer or nonemployer contributing entity to a defined benefit pension plan after the measurement date ofthe government's beginning net pension liability. GASB 71 will be effective for the Sewer Fund beginning with its year ending December 31, 2015. This statement amends paragraph 137 of GASB 68 to require that, at transition, a government recognize a beginning deferred outflow of resources for its pension contributions, if any, made subsequent to the measurement date of the beginning net pension liability and requires that beginning balances for other deferred outflows of resources and deferred inflows of resources related to pensions be reported at transition only if it is practical to determine all such amounts.
GASB Statement No. 72, Fair Value Measurement and Application ("GASB 72"), requires disclosures to be made about fair value measurements, the level of fair value hierarchy, and valuation techniques. Governments should organize these disclosures by type of asset or liability reported at fair value. It also requires additional disclosures regarding investments in certain entities that calculate net asset value per share (or its equivalent). GASB 72 will be effective for the Sewer Fund beginning with its year ending December 31, 2015.

Presentation Changes—The December 31, 2013 statement of net position has been changed to present the restricted assets and liabilities within their respective current and noncurrcnt classification categories. The restricted assets and liabilities were presented in a separate section in the prior year's basic financial statements. The December 31, 2013 Statement of Revenues, Expenses and Changes in Net Position has been changed to present the provision for doubtful accounts as a contra revenue account. Provision for doubtful accounts were presented as a component of operating expense in the prior year's basic financial statements. The December 31, 2013 statement of cash flows has been changed to present the transactions with other City funds on a gross basis. The transactions with other City funds were presented on a net basis in the prior year's basic financial statements.

Certain other investments are held in accordance with the specific provisions of applicable ordinances.
Credit Risk—The Code limits investments in commercial paper to banks whose senior obligations are rated in the top 10 rating categories by at least two national rating agencies and who are required to maintain such rating during the term of such investment. The Code also limits investments to domestic


-20-

money market mutual funds regulated by, and in good standing with, the Securities and Exchange Commission. Certificates of deposit are also limited by the Code to national banks that provide collateral of at least 102% by marketable U.S. government securities marked to market at least monthly; or secured by a corporate surety bond issued by an insurance company licensed to do business in Illinois and having a claims-paying rating in the top rating category, as rated by a nationally recognized statistical rating organization maintaining such rating during the term of such investment. A schedule summarizing the Sewer Fund's exposure to credit risk as of December 31, 2014 and 2013, is as follows (in thousands):

The Sewer Fund participates in the City's pooled cash and investments account, which includes amounts from other City funds and is maintained by the City Treasurer. Individual cash or investments arc not specifically identifiable to any participant in the pool. The Treasurer's pooled fund is included in the City's financial statements.
Custodial Credit Risk—Cash and Certificates of Deposit—This is the risk that in the event of a bank failure, the City's deposits may not be returned. The City's investment policy states that in order to protect the City's deposits, depository institutions are to maintain collateral pledges on City deposits during the term of the deposit of at least 102% of marketable U.S. government, or approved securities or surety bonds, issued by top-rated insurers. Collateral is required as security whenever deposits exceed the insured limits ofthe Federal Deposit Insurance Corporation. The bank balance of cash and certificates of deposit with the City's various municipal depositories was $318.2 million as of December 31, 2014. Of the bank balance, 98% was either insured or collateralized with securities held by City agents in the City's name. An amount of $7.4 million was uncollateralizcd at December 31, 2014, and thus was subject to custodial credit risk.

Interest expense includes amortization of the loss on bond refunding for 2014 and 2013 of $4.2 million; less amortization of net bond discount/premium of $3.2 million and $3.0 million, respectively; and accretion of Series 1998 capital appreciation bonds of $4.3 million and $4.1 million, respectively.
As defined in the ordinances, net revenues arc pledged for the payment of principal and interest on the bonds. The ordinances require that net revenues available for bonds equal 115% of the senior lien debt service requirement and that net revenues available for bonds equal the sum of 100% of the aggregate annual senior lien debt service requirement and 100% ofthe aggregate annual second lien debt service requirement. The above requirements were met for 2014 and 2013.
Rate Increases—Sewer service rates arc set by ordinance. The sewer service charge is established in an amount designed to pay the costs of Sewer Fund operations and capital improvements, including any related debt service. During 2014 and 2013, the charge for sewer service was increased and was an amount equal to 96% ofthe gross amount charged for water service, whether such water service is metered or nonmetered. The rate charged for water was increased and was $24.80 per 1,000 cubic feet and $21.56 per 1,000 cubic feet during 2014 and 2013, respectively.

Issuance of Debt—On October 2, 2012, a loan agreement was signed with the Illinois Environment Protection Agency to line existing sewer pipes throughout the city. In 2014, the Sewer Fund drew $15.0 million from this loan agreement. The loan has an interest rate of 2.295% with maturity dates from March 4, 2015, to September 4, 2034.
Second lien Wastewater Revenue Project, Series 2014 ($292.4 million) was sold at a premium in September 2014. The bonds have interest rates ranging from 3% to 5% and maturity dates from January 1, 2016 to January 1, 2044. Net proceeds of $322.2 million will be used to finance certain costs of improvements and extensions to the wastewater system ($320.0 million).

The Sewer Fund's variable-rate bonds may bear interest from time to time at a flexible rate, a daily rate, a weekly rate, an adjustable long rate, a fixed rate or an index rate as determined from time to time by the City in consultation with the remarketing agent, as applicable. At December 31, 2014, the variable-rate bonds were in the index rate interest mode. For the requirements calculated above, interest on variable-rate debt with principal of $332,230 was calculated at the swap rate in effect at December 31, 2014. The City has entered into continuing covenant agreements with the direct purchase providers, which expire on December 1, 2017. In the event the bonds are not successfully remarketed upon expiration, the bonds will convert to a term loan (sec Note 10 for subsequent events related to the effect ofthe ratings downgrade on the swap and liquidity agreements). There is no principal due on potential term loans within the next fiscal year.

Terms, Fair Values, and Credit Risk—The notional amounts of the swaps match the principal amounts of the associated debt. The Sewer Fund's swap agreements contain scheduled reductions to outstanding notional amounts that are expected to approximately follow scheduled or anticipated reductions in the associated "bonds payable" category. Under the swap, the Sewer Fund pays the counterparty a fixed payment and receives a variable payment computed according to the London InterBank Offered Rate (LIBOR) and/or the Securities Industry and Financial Markets Association (SIFMA). The terms, including the fair value and credit ratings of the outstanding swaps, as of December 31, 2014, are as follows (in thousands):

$(71,861)

Fair Value—As of December 31, 2014 and 2013, the swaps had a negative fair value of $71.9 million and $52.7 million, respectively. As per industry convention, the fair values of the Sewer Fund's outstanding swaps were estimated using the zero-coupon method. This method calculates the future net settlement payments required by the swap, assuming that the forward rates implied by the yield curve correctly anticipate future spot rates. These payments are then discounted using the spot rates implied by the current yield curve for hypothetical zero-coupon bonds due on the date of each future net settlement ofthe swap. Because interest rates declined subsequent to the date of execution, the Sewer Fund's swaps had negative values.

Credit Risk—The Sewer Fund is exposed to credit risk (counterparty risk) through the counterparties with which it enters into agreements. If minimum credit rating requirements arc not maintained, the counterparty is required to post collateral to a third party. This protects the Sewer Fund by mitigating the credit risk, and therefore the ability to pay a termination payment, inherent in a swap. Collateral on all swaps is to be in the form of cash or eligible collateral held by a third-party custodian. Upon credit events, the swaps also allow transfers, credit support, and termination, if the counterparty is unable to meet the said credit requirements.
Basis Risk—Basis risk refers to the mismatch between the variable-rate payments received on a swap contract and the interest payment actually owed on the bonds. The two significant components driving this risk are credit and SIFMA ratios. Credit may create basis risk because the Sewer Fund's bonds may trade differently than the swap index as a result of a credit change in the Sewer Fund. SIFMA ratios (or spreads) may create basis risk if SIFMA swaps ofthe Sewer Fund's bonds trade higher than the SIFMA received on the swap. This can occur due to many factors, including, without limitation, changes in marginal tax rates, tax-exempt status of bonds, and supply and demand for variable-rate bonds. The Sewer Fund is exposed to basis risk on the swaps if the rate paid on the bonds is higher than the rate received. The Sewer Fund is liable for the difference. The difference would need to be available on the debt service payment date and would add additional underlying cost to the transaction.




-27-
Swap Risk—The swap exposes the Sewer Fund to tax risk or a permanent mismatch (shortfall) between the floating rate received on the swap and the variable-rate paid on the underlying variable-rate bonds due to tax law changes such that the federal or state tax exemption of municipal debt is eliminated or its value reduced. There have been no tax law changes since the execution of the Sewer Fund's swap transactions.
Termination Risk—The risk that the swap could be terminated as a result of certain events, including a ratings downgrade for the issuer or swap counterparty, covenant violation, bankruptcy, payment default, or other defined events of default. Termination of a swap may result in a payment made by the issuer or to the issuer, depending upon the market at the time of termination.
Rollover Risk—The City may be exposed to rollover risk if the swap terminates early or if the term of the swap is shorter than that of the bonds.

6. PENSION PLANS
Eligible Sewer Fund employees participate in one of two of the City's single-employer defined benefit pension plans, which are separate units of government established under State law. These plans arc the Municipal Employees' and the Laborers' and Retirement Board Employees' Annuity and Benefit Funds ("Plans"). These Plans are administered by individual retirement boards represented by elected and appointed officials. Each plan issues publicly available financial statements for each ofthe pension plans, which may be obtained at the respective fund's office.
The Plans provide retirement, death, and disability benefits as established by State law. Benefits generally vest after 20 years of credited service. Employees who retire at or after age 55 with at least 20 years of credited service qualify to receive a money purchase annuity and those with more than 20 years of credited service qualify to receive a minimum formula annuity. The annuity is computed by multiplying the final average salary by a percentage ranging from 2.0 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. However, the State passed legislation in 2010 providing less generous benefits for employees who join one of the Plans after January 1, 2011.
Participating employees contribute 8.5% of their salary to the Plans as required by State law. By law, the City's contributions arc based on the amounts contributed by the employees. Financing of the City's contribution is through a separate property tax levy and the personal property replacement tax. The Sewer Fund reimburses the City's General Fund for the estimated pension cost applicable to the covered payroll of the Sewer Fund employees. These reimbursements, recorded as expenses of the Sewer Fund, were $5.0 million and $4.9 million in 2014 and 2013, respectively. The annual pension costs are determined using the entry age normal actuarial cost method and the level dollar amortization method.
Historically, State law required City contributions at statutorily, not actuarially, determined rates. The rates are expressed as multiples of employee contributions. These contributions equal employee contributions made in the calendar year two years prior to the year for which the applicable tax is levied, multiplied by the statutory rates. The statutory rates in effect for the City's contributions made during the years ended December 31, 2014 and 2013, were 1.25% for the Municipal Employees' Annuity and Benefit Fund and 1% for the Laborers' and Retirement Board Employees' Annuity and Benefit Fund. The City has made the required contributions under State law.
The City has made the required contributions under State law. In recent years, those contributions have been lower than the actuarially required amounts for the Plans, which have served to increase the Plans' unfunded actuarial liabilities. Recurring cash inflows from all sources to the Plans (including City contributions, employee contributions, and investment earnings) have been lower than the cash outlays ofthe Plans in some recent years. As a result, the Plans have liquidated investments and used assets of the Plans to satisfy their respective current payment obligations in those years. The use of assets by the Plans for these purposes reduces the amount of assets on hand to pay benefits or earn investment returns in the future.
Under the enacted State legislation for the Municipal Employees' and Laborers' Plans known as Public Act 98-641 ("P.A. 98-641"), the City is required to significantly increase contributions to those two Plans beginning in 2016. During the period 2016 through 2020, the City's contributions to the Municipal Employees' and Laborers' Plans increase by statutorily determined amounts, which are not based on actuarial calculations. Beginning in 2021, P.A. 98-641 requires the City to contribute in each year to the Municipal Employees' and Laborers' Plans, the amount needed for each Plan to achieve a 90% Funded Ratio by the end of 2055. P.A. 98-641 also makes certain modifications to the automatic annual adjustment of benefits for approximately 78,000 members of those Plans (including current retirees and all employees) and requires substantial increases in employee contributions toward the cost of their retirement benefits. The City has made the required contributions under State law.

The pension benefits information pertaining expressly to the Sewer Fund employees is not available, as the obligation is the responsibility of the general government. Accordingly, no amounts have been recorded in the accompanying basic financial statements for the net pension assets or liabilities of these Plans. Amounts for the City are recorded within the City's government-wide financial statements.
OTHER POSTEMPLOYMENT BENEFITS—CITY OBLIGATION
In addition to providing pension benefits, under State law, the City provides certain health benefits to employees who retire from the City based upon their participation in the City's pension plans. Substantially all employees who qualify as Municipal Employees' or Laborers' pension plan participants older than age 55 with at least 20 years of service may become eligible for postemployment benefits if they eventually become annuitants. Health benefits include basic benefits for annuitants and supplemental benefits for Medicare-eligible annuitants. Currently, the City does not segregate benefit payments to annuitants by fund. The cost of health benefits is recognized as claims arc reported and are funded on a pay-as-you-go basis. The total cost to the City for providing health benefits to approximately 24,381 annuitants and their dependents was approximately $79.3 million and S97.5 million in 2014 and 2013, respectively.

The annuitants who retired prior to July 1, 2005, received a 55% subsidy from the City and the annuitants who retired on or after July 1, 2005, received a 50%, 45%, 40%, and 0% 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 (the "Settlement Agreement"). During 2014 and 2013, the pension funds contributed $ $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 $84.8 million and $66.6 million in 2014 and 2013, respectively, to the gross cost of their retiree health care pursuant to premium amounts set forth in the Settlement Agreement discussed below.

The City's net expense and the annuitants' contribution indicated above are preliminary and subject to the reconciliation per the Settlement Agreement.

Plan Description Summary—The City of Chicago was party to a written legal settlement agreement outlining the provisions of the retiree health program, The Settlement Health Care Plans (the "Plans"), through June 30, 2013. Although the agreement did not extend continuation of the Plans after June 30, 2013, a phase out of three years to end the program was announced in 2013, with annual subsidy modifications and a final sunset of subsidies at December 31, 2016, for all but the Korshak class of members. As a result of the extension, the postsettlement plan-subsidized retiree medical benefits will cease for members as of December 31, 2016, except for the Korshak class 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.
The City administers a single employer, self-funded defined benefit healthcare plan (the "Health Plan"), for which the City pays a portion of the costs on a pay-as-you-go method. The City sponsors health benefit plans for employees, former employees and retired former employees. The provisions of the postsettlement benefit program 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 a specified period, recently revised to end on December 31, 2016. The percentage subsidies were revised to reduce by approximately 25% of 2013 subsidy levels in 2014 and 50 percent of 2013 subsidy levels in 2015. Additional step-downs in subsidy levels for 2016 have not yet been finalized.

In addition, State law authorizes the four respective Pension Funds (Police, Fire, Municipal, and Laborers) to provide a fixed monthly dollar subsidy to each annuitant who has elected coverage under the Health Plan through December 31, 2016. After that date, no supplements are authorized. The liabilities for the monthly dollar supplements paid to annuitants enrolled in the retiree medical plan by their respective Pension Funds are included in the actuarial valuation reports of the respective four Pension Funds.
Funding Policy—The City's retiree Health Plan is a single-employer plan, which operates on a pay-as-you-go funding basis. 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 postemployment benefit (OPEB) cost (expense) is calculated based on the annual required contribution (ARC) of the employer. The ARC represents a level of funding that if paid on an ongoing basis, is projected to cover the normal cost each year and to amortize any unfunded actuarial liabilities over a period of one year (the remaining years of coverage under the settlement agreement).
The following table shows the components of the City's annual OPEB costs for the year for the Health Plan, the amount actually contributed to the Health Plan, and changes in the City's net OPEB obligation to the Health Plan. The net OPEB obligation is the amount entered upon the City's statements of net position as of year-end as the net liability for the OPEBs. The amount of the annual cost for the Health Plan that is to be recorded in the statements of changes in net position for 2014 in the City CAFR is the annual OPEB cost (expense) (in thousands).

Funded Status and Funding Progress—As of December 31, 2013, the most recent actuarial valuation date, the actuarial accrued liability for benefits was $964.6 million, all of which was unfunded. The covered payroll (annual payroll of active employees covered by the Plans) was approximately $2,425.0 million and the ratio of the unfunded actuarial accrued liability to the covered payroll was 39.8%.
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 health care cost trend. Amounts determined

Actuarial Method and Assumptions—Projections of benefits for financial reporting purposes arc 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 AALs and the actuarial value of assets, consistent with the long-term perspective of the calculations.
For the Settlement Agreement benefits (not provided by the Pension Funds) in the actuarial valuation for the fiscal year ended December 31, 2014, the entry age normal actuarial cost method was used. The actuarial assumptions included an annual health care 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 2.5% inflation assumption. The plan has not accumulated assets and docs not hold assets in a segregated trust. However, the funds expected to be used to pay benefits arc assumed to be invested for durations which will yield an annual return rate of 3.0%. The UAAL is amortized as a level dollar amount over 10 years. The benefits include an extension of the Settlement Agreement sunset so as to completely phase out in December 2016. The Korshak category is entitled to lifetime benefits.

The OPEB information pertaining expressly to the Sewer Fund employees is not available as the obligation is the responsibility of the general government. Accordingly, no amounts have been recorded in the accompanying basic financial statements. Amounts for the City are recorded within the City's government-wide financial statements.

8. RELATED-PARTY TRANSACTIONS

Included in operating expenses are reimbursements to the General Fund of the City and certain other funds for services provided by other City departments, employee fringe benefits, and certain payments made on behalf of the Sewer Fund. Such reimbursements amounted to $36.7 million and $32.1 million in 2014 and 2013, respectively.
COMMITMENTS AND CONTINGENCIES 1
The Sewer Fund has certain contingent liabilities resulting from litigation, claims, or commitments incident to the ordinary course of business. Management expects that final resolution of these contingencies will not have a material adverse effect on the financial position or results of operations of the Sewer Fund.

The Sewer Fund provides workers' compensation benefits and employee health benefits under self-insurance programs administered by the City. Such claims outstanding, including claims incurred but not reported, arc estimated and recorded as liabilities in the basic financial statements.
Uninsured claim expenditures and liabilities are reported when it is probable that a loss has occurred and the amount of that loss can be reasonably estimated. These losses include an estimate for claims that have been incurred, but not reported. Changes in the claims liability amount for the years ended December 31, 2014 and 2013, are as follows (in thousands):

2014 2013
Balance—January 1 $ 16,784 $ 15,943
Claims incurred on current and prior-year events 12,996 13,108
Claims paid on current and prior-year events (12,406) (12,267)

Balance—December 31 $ 17,374 $ 16,784

The City purchases annuity contracts from commercial insurers to satisfy certain liabilities; accordingly, no liability is reported for those claims. Property and casualty risks for the Sewer Fund are transferred to commercial insurers. Claims have not exceeded the purchased insurance coverage in the past three years.

At December 31, 2014 and 2013, the Sewer Fund entered into contracts with outstanding commitments of approximately $113.6 million and $64.5 million, respectively, for construction projects.
SUBSEQUENT EVENT Ratings
In February 2015, Moody's Investors Service (Moody's) downgraded the ratings ofthe Wastewater senior lien revenue bonds from A2 to A3, and the Wastewater second lien revenue bonds from A3 to Baa 1, each with a negative outlook.

In May 2015, Moody's downgraded Wastewater senior lien bonds from A3 to Baa2 and the Wastewater second lien revenue bonds from Baal to Baa3, each with a negative outlook. The downgrades triggered events of defaults under certain continuing covenant agreements for the Series 2008C Wastewater Second Lien Revenue Bonds ("Series 2008C Bonds") where bondholders would have the right to


-35 -

demand immediate repayment if the event of default continues for a period of 90 days or, for one such bondholder, 180 days. It also triggered termination events under interest rate swap agreements to which the Sewer Fund is a party. In response to the triggering of these defaults and termination events, the City entered into forbearance agreements with the holders of its Series 2008C Bonds until July 1, 2016 and amended the interest rate swap agreements for its Series 2008C Bonds to remove such termination event from the swap agreements prior to any demand being made for a termination payment by the counterparties.

In May 2015, subsequent to the Moody's downgrade, Standard and Poor's (S&P) downgraded the Wastewater senior lien bonds from AA to A and the Wastewater second lien revenue bonds from AA- to A-, each with a negative watch.

Swaps
The City modified the Additional Termination Events rating thresholds related to its Second Lien Wastewater Transmission Revenue Bonds, Series 2008C swaps with JPMorgan ($49.8 million notional amount) and Bank of America ($49.8 million notional amount) from below Baal by Moody's or BBB+ by S&P to below Baa3 or BBB- by Moody's or S&P, respectively.
Continuing Covenant Agreements
Due to the May 2015 downgrade by Moody's, the City entered into forbearance agreements with the holders of its Series 2008C Bonds. Each of those holders has a continuing covenant agreement with the City with respect to its bonds. An event of default was triggered under each continuing covenant agreement due to the Moody's downgrade. The forbearance agreements extend to July 1, 2016 (provided that the City has taken certain steps prior to July 1, 2016 to convert the Series 2008C Bonds to fixed rates of interest), unless another event of default is triggered, including another rating downgrade by Moody's or a downgrade below investment grade by S&P or Fitch.

APPENDIX C
SUMMARY OF CERTAIN PROVISIONS OF THE INDENTURE
777e following is a summary of certain provisions of the Indenture not summarized elsewhere in this Official Statement. This summary does not purport to he complete or definitive and is qualified in its entirety by reference to the Indenture, a copy of which is on file with the Trustee.
Source of Payment; Pledge of Second Lien Bond Revenues
The provisions ofthe Indenture constitute a contract among the City, the Trustee and the Owners of the Bonds. The Bonds are legal, valid and binding limited obligations of the City payable solely from Second Lien Bond Revenues and certain other moneys and securities held by the Trustee under the Indenture. The Bonds, together with any other Second Lien Bonds, also are secured by and payable from any amounts on deposit in the Second Lien Construction Accounts. The Bonds and the interest thereon do not constitute an indebtedness of the City within the meaning of any constitutional or statutory provision or limitation as to indebtedness and shall have no claim to be paid from taxes of the City. The Bonds are secured by a pledge of the Second Lien Bond Revenues and funds and accounts held by the Trustee under the Indenture. The Bonds have a claim for payment from Second Lien Bond Revenues and from amounts on deposit in the Second Lien Construction Accounts on a parity with the claim of any other Second Lien Bonds that may be Outstanding from time to time.
Additional Second Lien Parity Bonds
(a) As long as there are any Bonds Outstanding, the City may issue Second Lien Parity Bonds for any lawful purpose of the Sewer System, including to refund Outstanding Senior Lien Bonds, Second Lien Bonds or obligations payable from revenues of the Sewer System on a basis subordinate to the Second Lien Bonds, upon compliance with the following conditions:
the funds required to be transferred to the Principal and Interest Account must have been transferred in full up to the date of the delivery of such Second Lien Parity Bonds; and
Net Revenues Available for Bonds for the last completed Fiscal Year prior to the issuance of the Second Lien Parity Bonds (as shown by the audit of an independent certified public accountant), or Net Revenues Available for Bonds for such last completed Fiscal Year, adjusted as described below, shall equal at least 100 percent of the sum of the Aggregate Senior Lien Debt Service and the Aggregate Second L ien Debt Service in each Fiscal Year following the issuance of the proposed Second Lien Parity Bonds, computed on a pro forma basis assuming the issuance of the proposed Second Lien Parity Bonds and the application of the proceeds of any Second Lien Parity Bonds as provided in the ordinance or trust indenture authorizing their issuance, sale and delivery. Net Revenues Available for Bonds may be adjusted as follows for purposes of this paragraph (ii):
(1) if prior to the issuance of such Second Lien Parity Bonds, the City has enacted
an increase in the rates of the Sewer System from the rates in effect for such last completed
Fiscal Year, Net Revenues Available for Bonds may be adjusted to reflect the Net Revenues
Available for Bonds for such last completed Fiscal Year as they would have been had the
increased rates been in effect during all of that last completed Fiscal Year; and
(2) any such adjustment shall be evidenced by a certificate of the Authorized
Officer.





C-l

For purposes of calculating the adjustment described in this paragraph (ii), any rate increase enacted by the City and scheduled to take effect in a future Fiscal Year may be reflected in Net Revenues Available for Bonds for purposes of calculating debt service coverage for that and each succeeding Fiscal Year.
If during the first six months of a Fiscal Year, an audit of the Sewer System for the preceding Fiscal Year by an independent certified public accountant is not available, the conditions of paragraph (ii) above shall be deemed to have been satisfied if both (A) Net Revenues Available for Bonds for the second preceding Fiscal Year (as shown by the audit of an independent certified public accountant), adjusted as described in paragraph (ii) above and (B)Net Revenues Available for Bonds for the preceding Fiscal Year (as estimated by the Authorized Officer), adjusted as described in paragraph (ii) above, shall equal at least 100 percent of the sum of the Aggregate Senior Lien Debt Service and the Aggregate Second Lien Debt Service in each Fiscal Year following the issuance of the proposed Second Lien Parity Bonds, computed on a pro forma basis assuming the issuance of the proposed Second Lien Parity Bonds and the application of the proceeds of any Second Lien Parity Bonds as provided in the ordinance or trust indenture authorizing their issuance, sale and delivery.
The City may issue Second Lien Parity Bonds without complying with either of the requirements of paragraph (a)(ii) above:

to pay, redeem or refund Senior Lien Bonds or Second Lien Bonds if in the judgment of the City there will be no money available to make payments of interest on or principal of those Senior Lien Bonds or Second Lien Bonds (at maturity or on Sinking Fund Payment dates) as such amounts become due; and
to pay, redeem or refund any Senior Lien Bonds or Second Lien Bonds if the sum of the Aggregate Senior Lien Debt Service and the Aggregate Second Lien Debt Service after the issuance of the Second Lien Parity Bonds and the payment, redemption or refunding of such Senior Lien Bonds or Second Lien Bonds will not be in excess of the sum of the Aggregate Senior Lien Debt Service or the Aggregate Second Lien Debt Service prior to the issuance of the Second Lien Parity Bonds in each Fiscal Year in which there was to be any Aggregate Senior Lien Debt Service or Aggregate Second Lien Debt Service on those prior Outstanding Senior Lien Bonds or Second Lien Bonds.
Other obligations, including Subordinate Lien Obligations, may be issued payable from Net Revenues Available for Bonds on a basis subordinate to the Second Lien Bonds.
Covenant Against Pledge of Second Lien Bond Revenues
The City agrees in the Indenture not to issue any bonds, notes or other evidences of indebtedness secured by the pledge contained in the Indenture, other than Second Lien Parity Bonds, and not to create or cause to be created any lien or charge on Net Revenues Available for Bonds, or on any amounts pledged for the benefit of Owners of Bonds under the Indenture, other than the pledge contained in the Indenture, provided that the Indenture does not prevent the City from (a) issuing Senior Lien Bonds, (b) issuing bonds, notes or other evidences of indebtedness payable out of, or secured by a pledge of, Net Revenues Available for Bonds to be derived on and after such date as the pledge contained in the Indenture shall be discharged and satisfied as provided in the Indenture, or (c) issuing bonds, notes or other evidences of indebtedness which are payable out of, or secured by, or to which are pledged, amounts which may be withdrawn from or secured by, the Second Lien Bonds Account so long as such pledge is expressly junior and subordinate to the pledge contained in the Indenture.

So long as the Bonds are Outstanding, to continue to operate the Sewer System as a revenue-producing system so as to produce Gross Revenues sufficient to satisfy the covenants ofthe Indenture.
Prior to the end of each Fiscal Year, to conduct a review to determine whether it has been and will be in compliance with the requirement described above under the subcaption "SECURITY FOR THE BONDS — Second Lien Rate Covenant" and, whenever this annual review indicates that the projected Gross Revenues will not be sufficient to comply with the rate covenant, to prepare or cause to be prepared a rate study for the Sewer System identifying the rate changes necessary to comply with the rate covenant, and the Director of the Office of Budget and Management ofthe City and the Authorized Officer shall recommend appropriate action to the City Council to comply with the rate covenant. See "FINANCIAL OPERATIONS— Annual Budget Review and Implementation of Annual Budget."
To make all necessary and proper repairs, replacements, additions and betterments to the Sewer System so that it may at all times be operated efficiently, economically and properly. When any necessary equipment or facility becomes worn out, destroyed or otherwise is insufficient for proper use, it shall promptly be replaced so that the value and efficiency of the Sewer System will be at all times fully maintained.
To establish such rules and regulations for the control and operation of the Sewer System as are necessary for the safe, lawful, efficient and economical operation of the Sewer System.
Remedies
Any Owner of a Bond may proceed by civil action to compel performance of all duties required by the Indenture, including the establishment and collection of sufficient fees, charges and rates for the services supplied by the Sewer System, and the application of Gross Revenues as provided in the Indenture.

The Trustee shall not be answerable for the exercise of any discretion or power under the Indenture or for anything whatsoever in connection with the trust created by the Indenture, except only for its own negligence or bad faith. Under the Indenture, the Trustee is required to exercise such of the rights and powers vested in it by the Indenture and use the same degree of skill and care in its exercise as a prudent person would use and exercise under the circumstances in the conduct of his or her own affairs; provided that the Trustee is under no obligation to take any action in respect of the execution or enforcement of any of the trusts created by the Indenture, or to institute, appear in or defend any suit or other proceeding in connection with such execution or enforcement, unless requested in writing so to do by Bondholders of at least a majority in aggregate principal amount of the Bonds then Outstanding, and, if in its opinion such action may tend to involve it in expense or liability, unless furnished from time to time as often as it may require, with security and indemnity satisfactory to it; but the foregoing provision is intended only for the protection of the Trustee.
The Trustee may execute any of the trusts or powers of the Indenture and perform the duties required under the Indenture by or through attorneys, agents or receivers, and is entitled to, and may rely upon, written advice of counsel concerning all matters of trust and duty under the Indenture, and the Trustee is not answerable for the negligence or misconduct of any such attorney or agent selected by it with reasonable care.
The Trustee may buy, sell, own, hold and deal in any of the Bonds for its own account or that of any other person, and may join in any action which any Bondholder may be entitled to take with like effect as if it did not act in any capacity under the Indenture. The Trustee, either as principal or agent, also may engage in or be interested in any financial or other transaction with the City and may act as depository, trustee or agent for any committee or body of Bondholders secured by the Indenture or other obligations of the City as freely as if it did not act in any capacity under the Indenture.
Resignation or Removal of Trustee
The Trustee may resign and be discharged of the trusts created by the Indenture by executing an instrument in writing resigning such trusts and specifying the date when such resignation shall take effect, and filing the same with the City, not fewer than 45 days before the date specified in such instrument when such resignation shall take effect, and by giving Notice by Mail of such resignation, not fewer than 21 days prior to such resignation date, to the Owners of Outstanding Bonds. Such resignation shall take effect on the day specified in such instrument and notice, but only if a successor Trustee has been appointed and has accepted the duties of the Trustee. If the successor Trustee shall not have been appointed within a period of 90 days following the giving of such notice, then the Trustee is authorized to petition any court of competent jurisdiction to appoint a successor Trustee.
The Trustee may be removed by the City at any time by filing with the Trustee an instrument or instruments in writing executed by the City, appointing a successor. Such removal shall be effective 30 days (or such longer period as may be set forth in such instrument) after delivery of the instrument; provided that no such removal shall be effective until the successor Trustee executes, acknowledges and delivers to the City an instrument accepting such appointment.
Appointment and Qualifications of Successor Trustee; Automatic Succession in Certain Events

If at any time the Trustee is removed, or is dissolved, or if its property or affairs are taken under the control of any state or federal court or administrative body because of insolvency or bankruptcy, or for any other reason, and if the Trustee shall resign, then the office of the Trustee shall be vacant immediately and a successor may be appointed by the City. After any such appointment, the City must cause notice of such appointment to be given to the predecessor Trustee and the successor Trustee, and must cause Notice by Mail to be given to all Bondholders. No such appointment will be effective until the successor Trustee has accepted such appointment.




C-7

If the Trustee resigns and no appointment of a successor Trustee is made pursuant to the provisions of the Indenture described above within 90 days following the giving of notice of resignation, the retiring Trustee may immediately apply to a court of competent jurisdiction for the appointment of a successor Trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor Trustee meeting the qualifications set forth in the Indenture.
Each successor Trustee must be a commercial bank with trust powers or a trust company (a) duly organized under the laws of the United States or any state or territory of the United States, (b) authorized under such laws to perform all the duties imposed upon it by the Indenture and the laws of the State, (c) capable of meeting its obligations under the Indenture, (d) subject to supervision or examination by Federal or state authority, and (e) with combined capital and surplus of at least $50,000,000. If the Trustee publishes reports of condition at least annually pursuant to law or the requirements of such authority, then for the purposes ofthe Indenture the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.
Any corporation into which any Trustee is merged or converted or with which it is consolidated, or any corporation resulting from any merger or consolidation to which any Trustee is a party, or any company to which all or substantially all of the corporate trust business of the Trustee is sold or transferred, shall be the successor Trustee under the Indenture, without the execution or filing of any paper or any further act on the part of the parties to the Indenture, anything in the Indenture to the contrary notwithstanding.

City of Chicago The Underwriters Listed
City Hall on Annex I
121 North LaSalle Street Chicago, Illinois 60602
Amalgamated Bank of Chicago, as trustee under the Trust Indenture defined below 30 North LaSalle Street, 38th Floor Chicago, Illinois 60603

We have examined a certified copy of the record of proceedings of the City of Chicago (the "City"), together with various accompanying certificates, pertaining to the issuance today by the City of $87,080,000 Second Lien Wastewater Transmission Revenue Bonds, Series 2015 (Taxable) (the "Bonds"). The record of proceedings includes an Ordinance adopted by the City Council of the City on September 24, 2015, providing for the issuance of the Bonds (the "Bond Ordinance"), a Trust Indenture, dated as of October 1, 2015 (the "Trust Indenture"), from the City to Amalgamated Bank of Chicago, as trustee (the "Trustee"), providing for the issuance of the Bonds, a Determination Certificate of the Chief Financial Officer ofthe City pursuant to the Bond Ordinance establishing certain terms of the Bonds and filed with the City Clerk pursuant to the Bond Ordinance (the "Determination Certificate"), and certificates of officers of the City, the Trustee and the purchasers of the Bonds as to various factual matters. Capitalized terms defined in the Bond Ordinance and the Trust Indenture and not otherwise defined in this opinion are used with the same meanings in this opinion.
The Bonds are being issued for the purposes of (i) refunding certain line of credit notes of the City incurred for the purpose of converting the City's outstanding Second Lien Wastewater Transmission Variable Rate Revenue Refunding Bonds, Series 2008C (the "Series 2008C Bonds") to bear interest at fixed rates including the termination of certain interest rate swaps related to the Series 2008C Bonds, (ii) paying the costs of converting the Series 2008C Bonds including funding a debt service reserve account for the Series 2008C Bonds, (iii) funding capitalized interest on the Bonds, (iv) funding the Debt Service Reserve Account for the Bonds, and (v) paying Costs of Issuance of the Bonds.
The Bonds are dated the date of this opinion and bear interest from their date until paid, payable semi-annually on January 1 and July 1 in each year, with the first interest payment date being January 1, 2016, at the rates per year, and mature on January 1 of each of the years and in the principal amounts provided in the Bond Ordinance and the Determination Certificate. The Bonds are subject to optional and mandatory sinking fund redemption in advance of their maturity as provided in the Bond Ordinance and the Determination Certificate.
Based upon this examination, we are of the opinion that:
The Bond Ordinance has been duly and lawfully adopted by the City, is in full force and effect and is valid and binding upon the City. The Determination Certificate has been duly authorized and executed by the City, is in full force and effect and is valid and binding upon the City.
The Trust Indenture has been duly authorized, executed and delivered by the City. Assuming the due authorization, execution and delivery of the Trust Indenture by the Trustee, the Trust Indenture is in full force and effect and is valid and binding upon the City.




D-1

October 19, 2015 Page 2
The Bonds are valid and legally binding limited obligations of the City. The Bonds, together with the City's Outstanding Second Lien Bonds and any Second Lien Parity Bonds which may be issued in the future, have a claim for payment, as to principal, redemption premium, if any, and interest, solely from the Second Lien Bond Revenues deposited into the 2015 Second Lien Bonds Subaccount established by the Bond Ordinance or comparable subaccounts established for other series of Second Lien Bonds in the Second Lien Bonds Account in the City's Sewer Revenue Fund and from certain other moneys held by the Trustee under the Trust Indenture, all as provided in the Bond Ordinance and the Trust Indenture. Second Lien Bond Revenues consist of Net Revenues Available for Bonds remaining in the Sewer Revenue Fund after required credits and deposits have been made to certain Senior Lien Accounts in the Sewer Revenue Fund pursuant to the ordinances authorizing the Outstanding Senior Lien Bonds and any Senior Lien Parity Bonds that the City may issue in the future. The Second Lien Bond Revenues have been irrevocably pledged to the payment of the Bonds on a parity with the Outstanding Second Lien Bonds and any Second Lien Parity Bonds that the City may issue in the future in accordance with the applicable provisions of the Trust Indenture and the ordinances and indentures authorizing the Outstanding Second Lien Bonds and any such Second Lien Parity Bonds at the time Outstanding. The Bonds do not have a claim for payment from taxes of the City.
The Bond Ordinance and the Trust Indenture create a valid pledge of the Trust Estate (as defined in the Trust Indenture), including Second Lien Bond Revenues and moneys and securities held in the Second Lien Bonds Account, subject to application of such moneys and securities in the manner provided in the Bond Ordinance and the Trust Indenture.
Interest on the Bonds under present law is not excludable from "gross income" for federal income tax purposes and thus is not exempt from federal income taxes based on gross income. Ownership of the Bonds may result in other federal tax consequences to certain taxpayers, and we express no opinion regarding any such collateral consequences arising with respect to the Bonds.
Interest on the Bonds is not exempt from present Illinois income taxes.
Ownership ofthe Bonds may result in other federal, state and local tax consequences to certain taxpayers and we express no opinion with respect to any such tax consequences with respect to the Bonds.
The rights of registered owners of the Bonds and the enforceability of provisions of the Bonds, the Bond Ordinance and the Trust Indenture may be subject to bankruptcy, insolvency, reorganization, moratorium and other similar laws affecting creditors' rights. Enforcement of provisions of the Bonds, the Bond Ordinance or the Trust Indenture by an equitable or similar remedy is subject to general principles of law or equity governing such a remedy, including the exercise of judicial discretion whether to grant any particular form of relief.
This opinion is based upon facts known or certified to us and laws in effect on its date and speaks as of that date. The opinions stated in this letter are expressions of professional judgment based upon such facts and law and are not a guaranty of a result if the validity or tax-exempt status of the Bonds are challenged. We have not undertaken any obligation to revise or supplement this opinion to reflect any facts or circumstances that may come to our attention after the date of this opinion or any changes in law that may occur after that date.
Respectfully yours,

RETIREMENT FUNDS
General

Pursuant to the Illinois Pension Code, as revised from time to time (the "Pension Code"), the City contributes to four retirement funds, which provide benefits upon retirement, death or disability to members of these retirement funds. Such retirement funds are, in order from largest to smallest membership: (i) the Municipal Employees' Annuity and Benefit Fund of Chicago ("MEABF"); (ii) the Policemen's Annuity and Benefit Fund of Chicago ("PABF"); (iii) the Firemen's Annuity and Benefit Fund of Chicago ("FABF"); and (iv) the Laborers' and Retirement Board Employees' Annuity and Benefit Fund of Chicago ("LABF" and, together with MEABF, PABF and FABF, the "Retirement Funds").
The Retirement Funds are established, administered and financed under the Pension Code, as separate bodies politic and corporate and for the benefit of the members of the Retirement Funds. The City's contributions to the Retirement Funds, and benefits for members of the Retirement Funds, are governed by the provisions ofthe Pension Code. See "— Determination of City's Contributions" below. This Appendix describes, among other things, the current provisions of the Pension Code applicable to the City's funding of the Retirement Funds. No assurance can be made that the Pension Code will not be amended in the future.

The Retirement Funds' funding sources are the City's contributions, the employees' contributions and investment income on the Retirement Funds' assets. The City's and employees' contribution levels are determined pursuant to the Pension Code.
The Retirement Funds have been actuarially determined to be significantly underfunded. See "— Funded Status of the Retirement Funds" and "— Projection of Funded Status" below. The funded status of the Retirement Funds has adversely impacted, and threatens to further negatively impact, the City and its taxpayers in several ways, certain of which are described in this paragraph and throughout this Appendix. First, the City's bond ratings have declined based, according to the reports of the rating agencies issued with respect to such downgrades, in part on the size of the Retirement Funds' unfunded liabilities and the projected impact of future City contributions to the Retirement Funds on the City. See "Impact of Retirement Funds' Unfunded Liabilities on the City's Bond Ratings" below. In addition, as described in the following paragraphs, the magnitude of the Retirement Funds' underfunding has prompted the Illinois General Assembly to pass legislation which would, as currently constituted, significantly increase the City's contributions to the Retirement Funds. Such additional contributions are expected to substantially burden the City's financial condition. Further, the governmental units with which the tax base of the City overlaps, which include, but are not limited to, the Chicago Board of Education of the City of Chicago (the "Board of Education"), the Chicago Park District ("CPD"), the County of Cook (the "County") and the State of Illinois (the "State") (collectively, all such other units are referred to herein as the "Governmental Units"), as described herein, have overlapping tax bases with the City and are also experiencing significant pension plan underfunding which, in combination with the current financial position of the Retirement Funds, places a substantial potential burden on the City's taxpayers who bear the burden of funding a portion of the contributions of the City and the Governmental Units. See "—Background Information Regarding the Retirement Funds—Overlapping Tax Bodies" below.



E-1

I











I
As noted above, in an effort to improve the funded status of the Retirement Funds, the Illinois General Assembly passed two statutes designed to improve the funding levels of the Retirement Funds: P.A. 98-641 (which is defined and described herein), which modifies provisions of the Pension Code related to MEABF and LABF, and P.A. 96-1495 (which is defined and described herein), which modifies provisions of the Pension Code with respect to PABF and FABF.
P.A. 98-641 significantly increases the City's contributions to MEABF and LABF and makes other adjustments that caused the unfunded liabilities of MEABF and LABF to decrease on its effective date and will cause such unfunded liabilities to decrease further over time. See "—Determination of City's Contributions—City's Required Contributions to LABF and MEABF Pursuant to P.A. 98-647" below. Information regarding projected future City contributions to LABF and MEABF pursuant to P.A. 98-641 is set forth in TABLE 13—"Projection of Future Funding Status—MEABF," TABLE 14— "Projection of Future Funding Status—LABF" and TABLE 18—"Projected Contributions: MEABF and LABF" below. P.A. 98-641 was determined to be unconstitutional by the Circuit Court of Cook County, Illinois (the "Circuit Court"). This decision is currently being appealed to the Illinois Supreme Court. See "—Legislative Changes—P.A. 98-641" below.
P.A. 96-1495 is expected to reduce the unfunded liabilities of PABF and FABF because it significantly increased future City contributions to be made by the City to PABF and FABF. See "— Determination of City's Contributions—City's Required Contributions to PABF and FABF Beginning in 2016" below. Unless modified by SB 777 (as defined and described herein) or similar legislation, P.A. 96-1495 has been projected to require an increase in the City's contributions to PABF and FABF from approximately $290 million in 2015 to approximately $839 million in 2016, with an increase of approximately three percent each year thereafter. See TABLE 15—"PROJECTION OF FUTURE FUNDING STATUS—FABF" and TABLE 16—"PROJECTION OF FUTURE FUNDING STATUS— PABF" below. In addition, as a result of certain changes to PABF's actuarial assumptions beginning with the 2014 Actuarial Valuation (as defined and described herein), the City's contributions to PABF are expected to increase by approximately $62 million for the 2017 Contribution. The City expects that the increases in the City's contributions to PABF and FABF mandated by P.A. 96-1495 will substantially burden the City's financial condition. Taken together with the increase in City contributions under P.A. 98-641, the burden on the City's financial condition would be even greater.
Certain statements made in this Appendix are based on projections, are forward-looking in nature and are developed using assumptions and information currently available. Such statements are subject to certain risks and uncertainties. The projections set forth in this Appendix rely on information produced by the Retirement Funds' independent actuaries (except where specifically noted otherwise) and were not prepared with a view toward complying with the guidelines established by the American Institute of Certified Public Accountants with respect to prospective financial information. This information is not fact and should not be relied upon as being necessarily indicative of future results. Readers of this Appendix are cautioned not to place undue reliance on the prospective financial information. Neither the City, the City's independent auditors, nor any other independent accountants have compiled, examined, or performed any procedures with respect to the prospective financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, the prospective financial information.

Certain of the comprehensive annual financial reports of the Retirement Funds (each a "CAFR" and together the "CAFRs"), and certain of the actuarial valuations of the Retirement Funds (each, an "Actuarial Valuation" and together, the "Actuarial Valuations"), may be obtained by contacting the Retirement Funds. Certain of these reports may also be available on the Retirement Funds' websites (www.meabf.org ; www.chipabf.org ; www.labfchicago.org ; and www.fabf.org ); provided, however, that the contents of these reports and of the Retirement Funds' websites are not incorporated herein by such reference.

The Retirement Funds typically release their Actuarial Valuations in the April or May following the close of their fiscal year on December 31. All of the Retirement Systems have released their 2014 Actuarial Valuations.
Background Information Regarding the Retirement Funds
General
Each of the Retirement Funds is a single-employer, defined-benefit public employee retirement system. "Single-employer" refers to the fact that there is a single plan sponsor, in this case, the City. "Defined-benefit" refers to the fact that the Retirement Funds pay a periodic benefit to employees upon retirement and survivors in a fixed amount determined at the time of retirement. The amount of the periodic benefit is generally determined on the basis of service credits and salary. Eligible employees receive the defined benefit on a periodic basis for life, along with certain benefits to spouses and children that survive the death of the employee.

To fund the benefits to be paid by a defined-benefit pension plan, both employees and employers make contributions to the plan. Generally in a defined-benefit pension plan, employees contribute a fixed percentage of their annual salary and employers contribute the additional amounts required (which amounts may be determined pursuant to statute, as in the case of the City), when combined with the investment earnings on plan assets, to pay the benefits under the pension plan. See "Table 1 -Membership," "—Determination of Employee Contributions" and "—Determination of City's Contributions" below.

The benefits available under the Retirement Funds accrue throughout the time an employee is employed by the City. Although the benefits accrue during employment, certain age and service requirements must be achieved by an employee to generate a retirement or survivor's periodic defined benefit payment upon retirement or termination from the City. The Retirement Funds also provide certain disability benefits and, until the later of the date on which the City no longer provides a health care plan for the annuitants or December 31, 2016, retiree healthcare benefits to eligible members.
Section 5 of Article XIII of the Illinois Constitution (the "Pension Clause") provides as follows:
"Membership in any pension retirement system of the State, any unit of local government or school district, or any agency or instrumentality thereof, shall be an enforceable contractual relationship, the benefits of which shall not be diminished or impaired."

For a discussion ofthe Pension Clause in the context of possible pension reform related to the Retirement Funds, see "—Pension Reform" below.
References in this Appendix to "member" are references to the active, inactive and retired employees of the City and their beneficiaries, the active, inactive and retired employees of the Retirement Funds participating in the Retirement Funds and their beneficiaries, and with regard to MEABF, certain employees of the Board of Education who are members of MEABF as described below, and their beneficiaries.
The Retirement Funds
Municipal Employees' Annuity and Benefit Fund of Chicago. MEABF is established by and administered under Article 8 ofthe Pension Code. MEABF provides age and service retirement benefits, survivor benefits and disability benefits to all eligible members. MEABF is administered under the direction of a five-member board of trustees (the "MEABF Board"), whose members are responsible for managing and administering MEABF for the benefit of its members. In addition to City and Retirement Fund employees, former employees and survivors, MEABF's membership includes non-instructional employees of the Board of Education ("CBOE Employees"). With respect to MEABF, the terms "employee" and "member" include the CBOE Employees. The CBOE Employees account for almost half of MEABF's membership. The Mayor of the City, the City Clerk, the City Treasurer, and members of the City Council may participate in MEABF if such persons file, while in office, written application to the MEABF Board.
Policemen's Annuity and Benefit Fund of Chicago. PABF is established by and administered under Article 5 of the Pension Code. PABF provides retirement and disability benefits to the police officers of the City, their surviving spouses and their children. PABF is administered by an eight-member board of trustees (the "PABF Board"). Members of the PABF Board are charged with administering the PABF under the Pension Code for the benefit of its members.

Firemen's Annuity and Benefit Fund of Chicago. FABF is established by and administered under Article 6 of the Pension Code. FABF provides retirement and disability benefits to fire service employees and their survivors. FABF is governed by an eight-member board of trustees (the "FABF Board"). Members of the FABF Board are statutorily mandated to discharge their duties solely in the interest of FABF's members.
Laborers' and Retirement Board Employees' Annuity and Benefit Fund of Chicago. LABF is established by and administered under Article 11 of the Pension Code. LABF provides retirement and disability benefits for employees of the City and the Board of Education who are employed in a title recognized by the City as labor service and for the survivors of such employees. LABF is governed by an eight-member board of trustees (the "LABF Board" and, together with the MEABF Board, the PABF Board and the FABF Board, the "Retirement Fund Boards"). Members of the LABF Board are statutorily mandated to discharge their duties solely in the interest of LABF's members.

The membership of the Retirement Funds as of December 31, 2014, was as follows:

Overlapping Taxing Bodies
The City's tax base overlaps with the Governmental Units, which includes, but is not limited to, the Board of Education, the CPD, the County and the State. Certain of the Governmental Units maintain their own defined benefit pension plans (collectively, all such other plans are referred to herein as the "Other Retirement Funds"), many of which are also significantly underfunded. The underfunding of these Other Retirement Funds places a substantial additional potential burden on the City's taxpayers, who bear the burden of funding a portion of the contributions of the Governmental Units.
State Pension Reform Act and Litigation. On May 8, 2015, the Illinois Supreme Court affirmed the decision of the Sangamon County Circuit Court that Public Act 98-0599 (the "State Pension Reform Act") is unconstitutional. The State Pension Reform Act would have provided for certain cost-saving and other reforms to the State's four largest pension plans, including, but not limited to, changes to the employee and employer contribution formula, cost of living adjustments, retirement ages and employee contributions. The State Pension Reform Act was challenged on behalf of various classes of annuitants, current and former workers, and labor organizations, alleging, among other things, that the legislation violates the Pension Clause.
Chicago Park District Pension Reform. On January 7, 2014, then Governor Pat Quinn signed Public Act 98-0622 into law (the "CPD Pension Reform Act"). The CPD Pension Reform Act provides for certain cost-saving and other reforms to CPD's pension plan, including, but not limited to, changes to the employee and employer contribution formula, cost of living adjustments, retirement ages and employee contributions. Such changes became effective on June 1, 2014. On October 8, 2015, participants in CPD's pension plan filed a lawsuit challenging the legality of the CPD Pension Reform Act by alleging, among other things, that the legislation violates the Illinois Pension Clause. The City makes no prediction as to whether the filing of this lawsuit or its outcome will impact the City's pension reform efforts.

The City believes the information on COGFA's website to be reliable; however, the City takes no responsibility for the continued accuracy of the Internet address or for the accuracy or timeliness of information posted on that website.

Certain Duties
Each Retirement Fund Board is a fiduciary of its respective Retirement Fund and is authorized to perform all functions necessary for operation of the Retirement Funds. The Pension Code authorizes each Retirement Fund Board to make certain decisions, including decisions regarding the investment of funds, the management of assets, the disbursement of benefits, and the hiring of staff, financial advisors and asset managers.

Each Retirement Fund Board is authorized to promulgate rules and procedures regarding their administration of benefits and other matters in accordance with the Illinois Administrative Procedure Act, and their decisions in awarding, limiting, or denying benefits are subject to the Illinois Administrative Procedure Act. Certain aspects of the Retirement Funds, however, including the defined benefits and the employer and employee contribution levels, are established in the Pension Code and may be amended only by an amendment to the Pension Code.
The Pension Code provides that the expenses incurred in connection with the administration of the Retirement Funds are not construed to be debt imposed upon the City. Such expenses are the obligation of the Retirement Funds exclusively, as separate bodies politic and corporate.
The Illinois Attorney General and annuitants may bring a civil action to obtain relief for violations of a fiduciary duty to the Retirement Funds or any act or practice which violates any provision of the Pension Code.

Investments
Each Retirement Fund Board manages the investments of its respective Retirement Fund. State law regulates the types of investments in which the Retirement Funds' assets may be invested. Furthermore, the Retirement Fund Boards invest the Retirement Funds' assets in accordance with the prudent person rule, which requires members of the Retirement Fund Boards, who are fiduciaries of the Retirement Funds, to discharge their duties with the care, prudence and diligence that a prudent person acting in a like capacity and familiar with such matters would use in a similar situation.
In carrying out their investment duty, the Retirement Fund Boards may appoint and review investment managers as fiduciaries to manage the investment assets of the Retirement Funds. Such investment managers are granted discretionary authority to manage the Retirement Funds' assets. Additional information regarding the Retirement Funds' investments and investment management may be found on the Retirement Funds' websites; provided, however, that the contents of such websites are not incorporated into this Appendix by such reference.

Funds.

Determination of Employee Contributions
Employees are required to contribute to their respective Retirement Fund as set forth in the Pension Code.
Prior to the implementation of P.A. 98-641 on January 1, 2015, MEABF employees contributed 8.5 percent of their salary to MEABF (consisting of a 6.5 percent contribution for employee benefits, a 1.5 percent contribution for spouse benefits, and a 0.5 percent contribution for an annuity increase benefit). For a summary of the increases in employee contributions that take effect under P.A. 98-641, see "—Legislative Changes —P.A. 98-641."

PABF employees contribute 9.0 percent of their salary to PABF (consisting of a 7.0 percent contribution for employee benefits, a 1.5 percent contribution for spouse benefits and a 0.5 percent contribution for an annuity increase benefit).

FABF employees contribute 9.125 percent of their salary to FABF (consisting of a 7.125 percent contribution for employee benefits, a 1.5 percent contribution for spouse benefits, a 0.375 percent contribution for an annuity increase benefit and a 0.125% contribution for disability benefits).

Prior to the implementation of P.A. 98-641 on January 1, 2015, LABF employees contributed 8.5 percent of their salary to LABF (consisting of a 6.5 percent contribution for employee benefits, a 1.5 percent contribution for spouse benefits, and a 0.5 percent contribution for an annuity increase benefit). For a summary of the increases in employee contributions that took effect under P.A. 98-641, see "— Legislative Changes —P.A. 98-641."

For each Retirement Fund, if an employee leaves without qualifying for an annuity, accumulated employee contributions are refunded.
Determination of City's Contributions
Under the Pension Code, the City's contributions to the Retirement Funds are determined pursuant to a statutory formula on an annual basis. Currently, the City's contributions equal the Multiplier Funding (as defined below) and certain other amounts as required by the Pension Code. "Multiplier Funding" is equal to the product of a multiplier established by the Pension Code for each Retirement Fund (each, a "Multiplier") and the amount contributed by the City's employees two years prior to the year in which the tax is levied. With respect to the City's 2015 contribution, the Multiplier for each Retirement Fund is as follows: 1.25 for MEABF; 2.00 for PABF; 2.26 for FABF; and 1.00 for LABF. The City's contributions are made as governed by the Pension Code and are not based on the Actuarially Required Contribution (as hereinafter defined). See "—The Actuarial Valuation—City's Contributions Not Related to GASB Standards" below. However, pursuant to P.A. 96-1495, beginning in 2016, the City's contributions to PABF and FABF will be determined pursuant to the P.A. 96-1495 Funding Plan (as hereinafter defined) rather than the Multiplier Funding system. See "—City's Contributions to PABF and FABF Beginning in 2016" below. P.A. 98-641 would change the manner of contributing to MEABF and LABF if the Illinois Supreme Court determines the law to be constitutional upon appeal. Under P.A. 98-641, beginning in 2021, P.A. 98-641 the City's contributions to MEABF and LABF would be determined pursuant to the P.A. 98-641 Funding Plan (as hereinafter defined) rather than the Multiplier Funding system. See "—City's Required Contributions to LABF and MEABF Pursuant to P.A. 98-641" below.

The Pension Code provides that the Retirement Fund Boards must each annually certify to the City Council a determination of the required City contribution to the Retirement Funds. In making its request for the City's annual contribution, each Retirement Fund, acting through its Retirement Fund Board, annually approves and then submits a resolution to the City Council requesting that the City Council levy for a particular contribution amount. The City has generally paid the amounts so requested. See "—City's Contributions to FABF" below.
The City's contributions to the Retirement Funds have historically been made primarily from the proceeds of an annual levy of property taxes for each of the Retirement Funds (collectively, the "Pension Levy") by the City solely for such purpose, as provided by the Pension Code. However, the Pension Code allows the City to use any other legally available funds (collectively, the "Other Available Funds," as described below) in lieu of the Pension Levy to make its contributions to the Retirement Funds. The amount of the Pension Levy, like any City property tax levy, must be approved by the City Council. The Pension Levy is exclusive of and in addition to the amount of property taxes which the City levies for other purposes.

If Other Available Funds are being utilized to pay a portion of the City's contributions, such funds are to be deposited with the City Treasurer to be used for the same purpose as the Pension Levy. The City's practice has been to use a portion of the City's Personal Property Replacement Tax revenue ("PPRT") to pay a portion of the City's contributions. PPRT revenue is paid by the State of Illinois (the "State") to the City from the Personal Property Replacement Tax Fund of the State pursuant to Section 12 ofthe Revenue Sharing Act of the State. The City's distributive share of PPRT is not required to be used for this purpose but it can be used by the City for corporate purposes. Since 2003, the amount of PPRT contributed by the City to the Retirement Funds in the aggregate has averaged approximately $78,387,000 annually. In 2012, 2013 and 2014, the amounts of PPRT contributed to the Retirement Funds in the aggregate were approximately $101,875,000, $126,639,000 and $127,239,000 respectively. For those same years, the City's total distributive share of PPRT was $139,461,000, $159,559,000 and


E-8

I I
$ 158,547,000, respectively. Beginning in 2016, the City changed the manner in which it accounts for the non-property tax portion of its pension contribution. The City now records PPRT directly into the General Fund, and the remaining portions from the General Fund and the Enterprise Funds are recorded directly into the respective Retirement Funds.

The contributions to the Retirement Funds in accordance with the Pension Code, which have been generally lower than the Actuarially Required Contribution, have contributed to the significant underfunding 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 as they become due. Any significant increases in the City's contributions (such as those scheduled to occur under P.A. 96-1495 and P.A. 98-641 if determined to be constitutional) to the Retirement Funds can be expected to place significant strain on the City's finances. As shown in TABLE 15—"Projection of Future Funding Status—FABF" and TABLE 16—"Projection of Future Funding Status—PABF" herein, the City's contributions to FABF and PABF are projected to increase in fiscal year 2016, when compared to fiscal year 2015, by approximately $134 million and $404 million, respectively, pursuant to the provisions of P.A. 96-1495. In addition, as shown in TABLE 13—"Projection of Future Funding Status—MEABF," TABLE 14—"Projection of Future Funding Status—LABF" and TABLE 18—"Projected Contributions—MEABF and LABF" herein, the City's contributions to MEABF and LABF would increase in fiscal year 2016, when compared to the City's contributions in fiscal year 2015, by approximately $80 million and $9 million, respectively pursuant to the provisions of P.A. 98-641, if such act is determined to be constitutional.
City's Contributions to FABF
With respect to the contribution to be made in 2015, the FABF has requested certain amounts which the City has determined are not required by the Pension Code. The amount requested by the FABF Board in excess of the amount the City has determined to be the statutory requirement for 2014 was $18,147,000. The FABF Board has made similar requests for amounts in excess of the amount the City has determined to be the statutory requirement in each of the last several years. In each such year, including the current year, the City has indicated that it will not contribute amounts in excess of the amount the City has determined to be the statutory contribution requirement for the City to FABF.
City's Required Contributions to PABF and FABF Beginning in 2016
Public Act 096-1495 ("P.A. 96-1495") was signed into law on December 30, 2010. Among other things, P.A. 96-1495 created a new method of determining the contributions to be made by the City to PABF and FABF. P.A. 96-1495 requires that, beginning in 2016, the City's contributions each year for PABF and FABF (the "P.A. 96-1495 Contribution ") will be equal to the amount necessary to achieve a Funded Ratio (as hereafter defined) of 90 percent in PABF and FABF by the end of fiscal year 2040 (the "P.A. 96-1495 Funding Plan").
Pursuant to the P.A. 96-1495 Funding Plan, the P.A. 96-1495 Contribution for PABF and FABF will be calculated as the level percentage of payroll necessary to reach the 90 percent Funded Ratio target by 2040. In Cook and DuPage Counties (in which the City is located), property taxes levied in one year become payable during the following year in two installments. As such, any property tax to be levied by the City for the purpose of raising the P.A. 96-1495 Contribution to be made by the City in 2016 would be levied in calendar year 2015 and collected in calendar year 2016.
Unless amended by the Illinois General Assembly, the P.A. 96-1495 Funding Plan will significantly increase the City's required contributions to PABF and FABF beginning in 2016 and will


E-9

impose a significant financial burden on the City. Based on the amounts budgeted by the City for the
contribution to PABF and FABF and the 2013 Actuarial Valuation for PABF and FABF, the City's required contribution to PABF and FABF is expected to increase by approximately $549 million in 2016 when compared to the contribution to be paid to such Retirement Funds in 2015. This contribution is expected to increase by an additional $62 million for fiscal year 2017 as a result of new assumptions to be used by the actuary for PABF beginning with the 2014 Actuarial Valuation. See "—Funded Status of the Retirement Funds" herein.
Senate Bill 777 ("SB 777") passed both houses of the Illinois General Assembly as of May 31, 2015. SB 777 would extend the period by which the unfunded liabilities of PABF and FABF are amortized to a 90 percent Funded Ratio from 2040 to 2055 (the "Revised Amortization Period") and institute a phase-in period during 2016-2020 to reduce the City's required payment in the initial years to allow for a more gradual phase-in of the requirements of P.A. 96-1495 (the "Phase-in Period"). The Revised Amortization Period would reduce the annual funding obligation required to reach a 90 percent Funded Ratio, but extend the number of years over which such payments would need to be made. A motion to reconsider the vote on SB 777 was filed in the Illinois Senate on May 31, 2015, and, as such, SB 777 has not been sent to the Governor for consideration. In addition to, or in lieu of, a Revised Amortization Period or a Phase-in Period, the Illinois General Assembly may consider other legislation that could affect the City payment obligations for PABF and FABF and/or funding sources for those obligations, including a City-owned casino. The City makes no representation as to whether or when SB 777 or any such other legislation would be enacted into law.

Any change to the P.A. 96-1495 Funding Plan which would reduce the contributions required of the City, such as a Revised Amortization Period or a Phase-in Period, would have the effect of increasing the unfunded liabilities and decreasing the Funded Ratios of PABF and FABF when compared to the projected unfunded liabilities and Funded Ratios of such Retirement Funds set forth in Tables 13 and 14 below. The City expects that the City Council will consider options for addressing its pension funding requirement for PABF and FABF, including improvements in operating efficiencies and incremental revenues, in late 2015. If an increase in property taxes were the sole source of incremental City contributions to PABF and FABF, and those contributions were not reduced by a Revised Amortization Period or Phase-in Period, the projected increase in the City's contribution to such Retirement Funds in
would be $549 million, as described above, on a total estimated 2015 aggregate tax levy of approximately $4.4 billion, including the City and overlapping taxing jurisdictions.

City's Required Contributions to LABF and MEABF Pursuant to P.A. 98-641
P.A. 98-641, which was determined to be unconstitutional by the Circuit Court, would modify the manner in which the City's contributions to LABF and MEABF are calculated. If P.A. 98-641 became effective, the Multiplier Funding system would be retained to calculate the City's contributions to LABF and MEABF for payment years 2016 through 2020 (unless the amount determined pursuant to the Multiplier Funding system for any year is more than the Normal Cost (as hereinafter defined) for such year plus the amount, determined on a level percentage of payroll basis, that is sufficient to achieve a Funded Ratio of 90 percent by the end of contribution year 2055). During this period, P.A. 98-641 would increase the Multiplier as follows: for the contribution made in 2016, 1.60 (LABF) and 1.85 (MEABF); for the contribution made in 2017, 1.90 (LABF) and 2.15 (MEABF); for the contribution made in 2018, 2.20 (LABF) and 2.45 (MEABF); for the contribution made in 2019, 2.50 (LABF) and 2.75 (MEABF); and for the contribution made in 2020, 2.80 (LABF) and 3.05 (MEABF). Beginning in 2021, the City's contributions for LABF and MEABF would equal the Normal Cost for such year plus the amount, determined on a level percentage of payroll basis, that is sufficient to achieve a Funded Ratio of 90 percent in LABF and MEABF by the end of contribution year 2055 (the "P.A. 98-641 Funding Plan").

The Circuit Court determined P.A. 98-641 to be unconstitutional on July 24, 2015. The City has appealed the Circuit Court's decision to the Illinois Supreme Court. See "Legislative Changes—P.A. 98-641" below. A decision by the Illinois Supreme Court to uphold the Circuit Court's decision regarding the constitutionality of P.A. 98-641 would have the effect of increasing the UAAL and decreasing the Funded Ratio of MEABF and LABF when compared to the law as modified by P.A. 98-641. See "— Effect on MEABF and LABF if P.A. 98-641 Found Unconstitutional" below for additional information regarding the effect of P.A. 98-641 being overturned on the funded status of MEABF and LABF.
City 's 2016 Contributions to the Retirement Funds Pursuant lo the Proposed Budget.

On September 22, 2015, the Mayor announced a proposed supplemental fiscal year 2015 budget (the "Proposed Supplemental Budget") and a proposed fiscal year 2016 budget (the "Proposed FY 2016 Budget"). The Proposed Supplemental Budget, if adopted, would increase the budgeted fiscal year 2015 contribution (payable in 2016) to PABF and FABF by $328 million (the "Proposed Additional 2015 Contribution") and would result in a total contribution to all of the Retirement Funds of $886 million (the "Proposed 2015 Contribution"). The Proposed FY 2016 Budget includes a budgeted fiscal year 2016 contribution (payable to the Retirement Funds in 2017) of $978 million (the "Proposed 2016 Contribution"). The Proposed 2015 Contribution and the Proposed 2016 Contribution each assume the effectiveness of P.A. 98-641 and the enactment of SB 777. The Proposed 2015 Contribution would represent an increase of $408 million over the City's budgeted 2014 contribution (payable in 2015) of $478 million due primarily to the increased contributions required for MEABF and LABF pursuant to P.A. 98-641 and the increased contributions required for PABF and FABF pursuant to SB 777 when compared to the law in effect prior to the adoption of P.A. 96-1495, as described above.
The City's budget for fiscal year 2015, as amended by the Proposed Supplemental Budget (together the "Proposed FY 2015 Budget"), would provide that the increase in contributions to PABF and FABF be primarily generated through an increase in the City's property tax levy with a small portion to be paid by the City's airports. The Proposed FY 2015 Budget and related tax levy are required to be filed with the County Clerks of the Counties of Cook and DuPage, Illinois, by the last Tuesday in December, 2015 (the "Filing Deadline"). As described above, the City's contributions to PABF and FABF were scheduled to increase by approximately $549 million under P.A. 96-1495 to a total contribution of $839 million. The enactment of SB 777 would reduce such contribution to $619 million. If the Proposed FY 2015 Budget, including the Proposed Supplemental Contribution, is adopted by the City Council and SB 777 has not been enacted prior to the Filing Deadline, the City expects that it would amend the Proposed FY 2015 Budget and make the additional necessary contributions required by P.A. 96-1495.
The Actuarial Valuation
General

The Pension Code requires that the Retirement Funds annually submit to the City Council a report containing a detailed statement of the affairs of such Retirement Fund, its income and expenditures, and assets and liabilities, which consists of the Actuarial Valuation. With respect to the Retirement Funds, the Actuarial Valuation measures the financial position of a Retirement Fund, determines the amount to be contributed by the City to such Retirement Fund pursuant to the statutory requirements described above, and produces certain information mandated by the financial reporting standards issued by the Governmental Accounting Standards Board, as described below.

In producing the Actuarial Valuations, the Retirement Funds' actuaries use demographic data (including employee age, salary and service credits), economic assumptions (including estimated future salary and interest rates), and decrement assumptions (including employee turnover, mortality and


E-11

retirement rates) to produce the information required by the Prior GASB Standards or the New GASB Standards, each as hereinafter defined. The Retirement Funds' Actuarial Valuations are publicly available and may be obtained from the Retirement Funds. See "—Source Information" above. A description of the statistics generated by the Retirement Funds' actuaries in the Actuarial Valuations follows in the next few paragraphs. This information was derived from the Source Information.
GASB, which is part of a private non-profit corporation known as the Financial Accounting Foundation, promulgates standards regarding accounting and financial reporting for governmental entities. These principles have no legal effect and do not impose any legal liability on the City. The references to GASB principles in this Appendix do not suggest and should not be construed to suggest otherwise.
Prior GASB Standards
For the fiscal years discussed in this Appendix prior to and including December 31, 2013, the applicable GASB financial reporting standards were GASB Statement No. 25 ("GASB 25") and GASB Statement No. 27 ("GASB 27" and, together with GASB 25, the Prior GASB Standards"). The Prior GASB Standards required the determination of the Actuarially Required Contribution and the calculation of pension funding statistics such as the UAAL and the Funded Ratio in the Actuarial Valuation. In addition, the Prior GASB Standards allowed pension plans to prepare financial reports pursuant to a variety of approved actuarial methods, certain of which are described in "—Actuarial Methods" below.
GASB 25 required disclosure of an "Actuarially Required Contribution," which was such pronouncement's method for calculating the annual amounts needed to fully fund the Retirement Funds, though the Actuarially Required Contribution was a financial reporting requirement and not a funding requirement. The Prior GASB Standards referred to the Actuarially Required Contribution as the "Annual Required Contribution"; however, this Appendix refers to the concept as the Actuarially Required Contribution to denote the fact that the Actuarially Required Contribution is the amount an actuary would calculate pursuant to the Prior GASB Standards to be contributed in a given year, to differentiate it from the amount the City will be required to contribute under the Pension Code.
The Actuarially Required Contribution as defined in GASB 25, consisted of two components: (1) that portion of the present value of pension plan benefits which is allocated to the valuation year by the actuarial cost method (as described in "—Actuarial Methods—Actuarial Accrued Liability" below), termed the "Normal Cost"; and (2) an amortized portion of any UAAL (defined below).
The Actuarial Accrued Liability was an estimate of the present value of the benefits each Retirement Fund must pay to members as a result of past employment with the City and participation in such Retirement Fund. The Actuarial Accrued Liability was calculated by use of a variety of demographic and other data (such as employee age, salary and service credits) and various assumptions (such as estimated salary increases, interest rates, employee turnover, retirement date and age and mortality and disability rates). The Actuarial Value of Assets reflected the value of the investments and other assets held by each Retirement Fund. Various methods existed under the Prior GASB Standards for calculating the Actuarial Value of Assets and the Actuarial Accrued Liability. For a discussion of the methods and assumptions used to calculate the Retirement Funds' Actuarial Accrued Liability and Actuarial Value of Assets under GASB 25, see "—Actuarial Methods" and "—Actuarial Assumptions" below.
Any shortfall between the Actuarial Value of Assets and the Actuarial Accrued Liability was referred to as the "Unfunded Actuarial Accrued Liability" or "UAAL." The UAAL represented the present value of benefits attributed to past service that are in excess of plan assets. In addition, the


E-12

i
I


I


!
actuary computed the "Funded Ratio," which was the Actuarial Value of Assets divided by the Actuarial Accrued Liability, expressed as a percentage. The Funded Ratio and the UAAL provide one way of measuring the financial health of a pension plan.
New GASB Standards
Beginning with the fiscal year ended December 31, 2014, GASB 25 was replaced with GASB Statement No. 67 ("GASB 67"), and GASB 27 will be replaced with GASB Statement No. 68 beginning with the fiscal year ending December 31, 2015 ("GASB 68" and, together with GASB 67, the "New GASB Standards"). Unlike the Prior GASB Standards, the New GASB Standards do not establish approaches to funding pension plans. Instead, the New GASB Standards provide standards solely for financial reporting and accounting related to pension plans. The New GASB Standards require calculation and disclosure of a "Net Pension Liability," which is the difference between the actuarial present value of projected benefit payments that is attributed to past periods of employee service calculated pursuant to the methods and assumptions set forth in the New GASB Standards (referred to in such statements as the "Total Pension Liability") and the fair market value of the pension plan's assets (referred to as the "Fiduciary Net Position"). This concept is similar to the UAAL, which was calculated under the Prior GASB Standards, but most likely will differ from the UAAL on any calculation date because the Fiduciary Net Position is calculated at fair market value and because of the differences in the manner of calculating the Total Pension Liability as compared to the Actuarial Accrued Liability under the Prior GASB Standards.
Furthermore, the New GASB Standards employ a rate, referred to in such statements as the "Discount Rate," which is used to discount projected benefit payments to their actuarial present values. The Discount Rate may be a blended rate comprised of (1) a long-term expected rate of return on a Retirement Fund's investments (to the extent that such assets are projected to be sufficient to pay benefits), and (2) a tax-exempt municipal bond rate meeting certain specifications set forth in the New GASB Standards. Therefore, in certain cases in which the assets of a Retirement Fund are not expected to be sufficient to pay the projected benefits of such Retirement Fund, the Discount Rate calculated pursuant to the New GASB Standards may differ from the assumed investment rate of return used in reporting pursuant to the Prior GASB Standards.
Finally, the New GASB Standards require that the Net Pension Liability be disclosed in the notes to the financial statements of the pension system and that a proportionate share of the Net Pension Liability be recognized on the balance sheets of the employer. In addition, the New GASB Standards require an expense (the "Pension Expense") to be recognized on the income statement of the City. The recognition ofthe Net Pension Liability and the Pension Expense do not measure the manner in which a Retirement Fund is funded and therefore do not conflict with the various manners of funding the Retirement Funds described in this Appendix.
As stated above, GASB 67 was first applied with respect to the Actuarial Valuation for the fiscal year ended December 31, 2014. The City expects that the New GASB Standards may significantly alter the financial statements produced by the City. For example, the Retirement Funds disclosed a combined Net Pension Liability of $20.1 billion as of December 31, 2014, which will impact the City's balance sheet in future years. However, because the City contributes to the Retirement Funds pursuant to the methods established in the Pension Code, the New GASB Statements will not materially impact the contributions made by the City without legislative action.
City's Contributions Not Related to GASB Standards

The City's contributions to the Retirement Funds are not based on the contribution calculations promulgated by GASB for reporting purposes. Instead, the City's contributions are calculated pursuant to the formulas established in the Pension Code. See "— Determination of City's Contributions" above.


E-13

The methods for contributing to the Retirement Funds set forth in the Pension Code do not conform to the manner of funding established by the Prior GASB Standards which funding was based on the Actuarially Required Contribution. The difference between the City's actual contributions and the Actuarially Required Contribution (as calculated by the Retirement Funds' actuaries) for fiscal years 2005-2014 is shown in TABLE 4—"Information Regarding City's Contributions—Aggregated" below. Each Retirement Fund's Actuarially Required Contribution is equal to its Normal Cost plus an amortization of the Retirement Funds' UAAL over a 30-year period. MEABF, LABF and FABF amortize the UAAL on a level dollar basis, whereas PABF amortizes the UAAL on a level percent of payroll basis. P.A. 98-641 would require amortization for LABF and MEABF on a level percent of payroll basis. Both methods of calculating the Actuarially Required Contribution were acceptable under the Prior GASB Standards.
Furthermore, beginning in 2016 with respect to PABF and FABF under the P.A. 96-1495 Funding Plan and, if P.A. 98-641 is determined to be constititutional, not later than 2021 with respect to MEABF and LABF under the P.A. 98-641 Funding Plan, the City will contribute an actuarially determined amount, as opposed to the current, non-actuarial, multiplier-based approach, as set forth in the Pension Code. The P.A. 96-1495 Funding Plan and the P.A. 98-641 Funding Plan differ from the manner of calculation required by the Prior GASB Standards for financial reporting purposes, primarily because the goal of such funding plans is to reach a Funded Ratio in the respective Retirement Funds of 90 percent whereas the Prior GASB Standards required the Retirement Funds to amortize the UAAL towards attainment of a 100 percent Funded Ratio.
The New GASB Standards do not require calculation of an Actuarially Required Contribution.
Actuarial Methods
The Retirement Funds' actuaries employ a variety of actuarial methods to arrive at the pension statistics required by the Prior GASB Standards and the New GASB Standards. Certain of these methods are discussed in the following sections.
Actuarial Value of Assets

Under the Prior GASB Standards, the Retirement Funds calculate their respective Actuarial Value of Assets by smoothing investment gains and losses over a period of five years, a method of valuation referred to as the "Asset Smoothing Method." Under the Asset Smoothing Method, the Retirement Funds recognize in the current year 20 percent ofthe investment gain or loss realized in that year and each of the previous four years. The Asset Smoothing Method was an allowable method of calculating the Actuarial Value of Assets under the Prior GASB Standards.
The Asset Smoothing Method lessens the immediate impact of market fluctuations on the Actuarial Value of Assets, which is used to calculate the UAAL and the Funded Ratio, that may otherwise occur as a result of market volatility. However, asset smoothing delays recognition of gains and losses, thereby providing an Actuarial Value of Assets that differs from the market value of pension plan assets at the time of measurement. As a result, presenting the Actuarial Value of Assets as determined under the Asset Smoothing Method might provide a more or less favorable presentation of the current financial position of a pension plan than would a method that recognizes investment gains and losses annually.
As described above, under the New GASB Standards, the Fiduciary Net Position is equal to the fair market value of a pension plan's assets as of the date of determination. As such, the Asset Smoothing Method does not apply to the determination of the Fiduciary Net Position under the New GASB Standards.

2005 through 2010 data is from the Actuarial Valuations ofthe Retirement Funds as of December 31. 2010, and from the Retirement Fund CAFRs for the fiscal year ended December 31, 2010. Data from 2011 through 2014 is from the Actuarial Valuations ofthe Retirement Funds for the fiscal years 2011 through 2014. In thousands of dollars. Data is presented in the aggregate for the Retirement Funds. The Actuarial Value of Assets is calculated through use ofthe Asset Smoothing Method.
A ctuarial A ccrued Liability
As the final step in the calculation of actuarial liabilities, the actuary applies a cost method to allocate the total value of benefits to past, present and future periods of employee service. This allocation is accomplished by the development of the Actuarial Accrued Liability and the Normal Cost under the Prior GASB Standards and the Pension Code and the Total Pension Liability under the New GASB Standards. Currently, all of the Retirement Funds use the entry age normal actuarial cost method (the "EAN Method") with costs allocated on the basis of earnings. The EAN Method was an approved actuarial cost method under the Prior GASB Standards and is the only allowable actuarial cost method under the New GASB Standards.
Under the EAN Method, the present value of each employee's projected pension is assumed to be funded by annual installments equal to a level percentage of the employee's earnings for each year between entry age and assumed exit age. Each employee's Normal Cost, as calculated pursuant to the Prior GASB Standards, for the current year is equal to the portion of the value so determined, assigned to the current year. Therefore, the Normal Cost for the plan for the year is the sum of the Normal Costs of all employees.

P.A. 96-1495 requires that, beginning in 2016, PABF and FABF calculate the Actuarial Accrued Liability pursuant to the projected unit credit actuarial cost method (the "PUC Method"). Under the PUC Method, Normal Cost represents the actuarial present value of that portion of an employee's projected benefit that is attributable to service in the current year, based on future compensation projected to retirement. Under this method, the Actuarial Accrued Liability equals the actuarial present value of that portion of a member's projected benefit that is attributable to service to date, again, on the basis of future compensation projected to retirement.



E-15

Under either cost method, the Actuarial Accrued Liability is the portion of the present value of benefits assigned by the cost method to years of service up to the valuation date, i.e., for past service. This value changes as the employee's salary changes and years of service increase, and as some employees leave and new employees are hired. Future Normal Cost is the portion of the present value of benefits assigned to future years of service and is assumed to be funded annually.

As compared to the EAN Method, the PUC Method will produce a more back-loaded growth in liabilities because the PUC Method allocates a higher portion of retirement costs closer to the time of retirement. Therefore, the PUC Method results in a slower accumulation of assets, which in turn requires smaller initial, and larger future, contributions (assuming funding is actuarially based, as under the P.A. 96-1495 Funding Plan and under P.A. 98-641). Deferring contributions in this manner increases the cost ofthe liabilities and the associated financial risks for PABF and FABF.
Actuarial Assumptions
The Actuarial Valuations of the Retirement Funds use a variety of assumptions in order to calculate the statistics required by the Prior GASB Standards and the New GASB Standards. Although several of the assumptions are the same across all of the Retirement Funds, each Retirement Fund determines, within actuarial standards, the assumptions to be used in its Actuarial Valuation unless a specific assumption is fixed by the Pension Code. No assurance can be given that any of the assumptions underlying the Actuarial Valuations will reflect the actual results experienced by the Retirement Funds. Variances between the assumptions and actual results may cause increases or decreases in the statistics calculated pursuant to the Prior GASB Standards or the New GASB Standards. Additional information on each Retirement Fund's actuarial assumptions is available in the respective 2014 Actuarial Valuations of the Retirement Funds. See "—Source Information" above.
The actuarial assumptions used by the Retirement Funds are determined by the individual Retirement Fund Boards upon the advice of the actuary for each Retirement Fund Board. The Retirement Funds periodically perform experience studies to evaluate the actuarial assumptions in use. The purpose of an experience study is to validate that the actuarial assumptions used in the Actuarial Valuation continue to reasonably estimate the actual experience of the pension plan or, if necessary, to develop recommendations for modifications to the actuarial assumptions to ensure their continuing appropriateness.
Assumed Investment Rale of Return
The Actuarial Valuations assume an investment rate of return on the assets in each Retirement Fund. The average long-term investment rates of return currently assumed by the Retirement Funds are described in Table 2 above. Due to the volatility of the marketplace, however, the actual rate of return earned by the Retirement Funds on their assets in any year may be higher or lower than the assumed rate. Changes in the Retirement Funds' assets as a result of market performance will lead to an increase or decrease in the UAAL and the Funded Ratio. As a result of the Retirement Funds' use of the Asset Smoothing Method, however, only a portion of these increases or decreases will be recognized in the current year, with the remaining gain or loss spread over the remaining four years. See "—Actuarial Methods—Actuarial Value of Assets" above.
The assumed investment rate of return is used by each Retirement Fund's actuary as the discount rate to determine the present value of future payments to such Retirement Fund's members. Such a determination is part of the actuary's process to develop the Actuarial Accrued Liability under the Prior GASB Standards. Reducing the assumed investment rate of return will, taken independently of other changes, produce a larger Actuarial Accrued Liability for each Retirement Fund. Furthermore, as


E-16

discussed above, an increase in the Actuarial Accrued Liability will, taken independently, increase the UAAL, decrease the Funded Ratio and increase the Actuarially Required Contribution.
Under the New GASB Standards, each Retirement Fund's actuary will calculate the Discount Rate, as described under "—Actuarial Valuation" above, a reduction in which will, taken independently of other factors, produce a larger Total Pension Liability for each Retirement Fund. Information regarding the Discount Rate and the sensitivity of the Total Pension Liability to changes in the Discount Rate is provided below in Table 12.
Beginning with calendar year 2012, the Retirement Fund Boards of MEABF, LABF and PABF reduced the assumed investment rate of return to be used by their respective actuaries in preparing future actuarial valuations. For MEABF and LABF, the assumed investment rate of return has been decreased to 7.50 percent beginning with calendar year 2012. For PABF, the assumed investment rate of return was decreased to 7.75 percent for calendar year 2012 and to 7.50 percent for calendar year 2014. FABF continues to assume an investment rate of return of 8.0 percent. For a discussion ofthe rate to be used by Moody's in analyzing public pension plans, see "—Impact of Retirement Funds' Unfunded Liability on the City's Bond Ratings" below.
These changes to the assumed investment rate of return will not impact contributions by the City to Retirement Funds when such contributions are determined pursuant to the Multiplier Funding System. However, beginning in 2016 with respect to PABF and no later than 2021 with respect to MEABF and LABF, when P.A. 96-1495 and P.A. 98-641, respectively, become effective and the City contributes to the Retirement Funds on an actuarial basis, such changes in the assumed investment rate of return will, taken independently of other facts, increase the City's contributions to such Retirement Funds because the respective UAALs of PABF, LABF and MEABF will increase as described above and the P.A. 96-1495 Funding Plan and the P.A. 98-641 Funding Plan require an amortization of the UAAL to reach a 90 percent funding target by 2040 and 2054, respectively.
Funded Status ofthe Retirement Funds
In recent years, the City has contributed to the Retirement Funds the full amount of Multiplier Funding and certain other amounts determined by the City to be required by the Pension Code through a
combination of property tax revenues (through the Pension Levy) and PPRT funds. However, these amounts have not been sufficient to fully fund the Retirement Funds' Actuarially Required Contributions. Moreover, expenses related to the Health Plan (as defined below) are paid from the City's contributions, which has the effect of reducing the Actuarial Value of Assets and decreasing the Funded Ratio.
Furthermore, the income from all sources (including employee contributions, City contributions and investment earnings) to the Retirement Funds has been lower than the cash outlays of the Retirement Funds in some recent years. As a result, the Retirement Funds have liquidated investments and used assets ofthe Retirement Funds to satisfy these cash outlays. The use of investment earnings or assets of the Retirement Funds for these purposes reduces the amount of assets on hand to pay benefits in the future and prevents the Retirement Funds from recognizing the full benefits of compounding investment returns.
Table 4 provides information on the Actuarially Required Contribution, the City's actual contributions in accordance with the Pension Code and the percentage of the Actuarially Required Contribution made in each year.


As discussed under""— Determination of City's Contributions'" above, the City and FABF have disagreed over whether certain amounts arc required under the Pension Code. In addition, pursuant to the Pension Code, the City did not make any contributions to LABF in fiscal years 2001 through 2006 because LABF had funds on hand in excess of its liabilities. The Pension Code provides that the City will cease lo make contributions to LABF in such a situation The City continued to make contributions to the other Retirement Funds during those years

December 31, 2012 and December 31, 2013.
In thousands of dollars. Data is presented in the aggregate for the Retirement Funds and uses assumptions and methods employed by each of the Retirement Funds. For the data presented as of December 31. 2005 and December 31. 2006, contribution information includes amounts related lo other posl-employment benefits. Beginning in 2007. as a result of a change in GASB standards, contribution information is presented exclusive of amounts related to other post-employment benefits.
Includes the portion ofthe PPRT contributed to the Retirement Funds in each year.
The estimated multipliers that would have been necessary for FABF, LABF and PABF to make the full Actuarially Required Contribution in 2014 were as follows: 7.98 for FABF; 4.87 for LABF: and 7.94 for PABF. The estimated multiplier that would have been necessary for MLABF to make the full Actuarially Required Contribution in 2014 has not been publicly disclosed, however the necessary contribution multiple for 2013 was 4.52. Beginning in 2016, the City"s contributions to PABF and FABF will not be calculated in accordance with the Multiplier Funding system. Pursuant to P.A. 98-641, the City's contributions to LABF and MEABF will not be calculated in accordance with the Multiplier Funding system beginning in 2021. See "—Determination of City's Contributions" above.
Beginning in 2006, as a result of a change in GASB standards, the information in this fable 4 does not include other post-employment benefits, which the City's Comprehensive Annual Financial Report presents separately.
PABF changed certain actuarial assumptions beginning with the fiscal year ended December 31, 2014. Specifically, PABF reduced its assumed investment rate of return from 7.75 percent to 7.50 percent and changed the mortality table used by its actuary to RP-2014, which projects longer lives for PABF members. Considered independently of other factors, these changes increased the GASB 25 Actuarial Accrued Liability, and, as a result, increased PABF's UAAL and Actuarially Required Contribution. With respect to the City's 2017 contribution to PABF, these changes are expected to result in an additional contribution of $62 million.
The continued decline in the percentage of the Actuarially Required Contribution contributed by the City, as shown in Table 4 above, results, in part, from the fact that the actuarial liability continues to grow due to the delayed recognition of gains and losses resulting from the Retirement Funds' use of the Asset Smoothing Method for financial reporting purposes under the Prior GASB Standards. See "— Actuarial Methods—Value of Assets" above.

The following tables summarize the financial condition and the funding trends of the Retirement
Funds.

A variety of factors impact the Retirement Funds' UAAL and Funded Ratio. A lower return on investment than that assumed by the Retirement Funds, and insufficient contributions when compared to the Normal Cost plus interest will all cause an increase in the UAAL and a decrease in the Funded Ratio. Conversely, higher returns on investment than assumed, and contributions in excess of Normal Cost plus interest will decrease the UAAL and increase the Funded Ratio. In addition, legislative amendments, changes in actuarial assumptions and certain other factors (including, but not limited to, higher or lower incidences of retirement, disability, in-service mortality, retiree mortality or terminations than assumed) will have an impact on the UAAL and the Funded Ratio.
Net Pension Liability and Discount Rate
As described in "—Actuarial Valuation—New GASB Standards'' above, the New GASB Standards require the calculation of the Net Pension Liability, which is the difference between the Total Pension Liability and the Fiduciary Net Position. Furthermore, the Discount Rate is the blended rate at which the actuaries of the Retirement Funds discount projected benefit payments to their actuarial present values. The following tables present information on the Net Pension Liability and the components thereof and the Discount Rate and the sensitivity of the Net Pension Liability to changes in the Discount Rate. As described in this Appendix, the fiscal year ended December 31, 2014 is the first fiscal year for which GASB 67 is effective and, as such, comparative historical information is not yet available with respect to the information provided in these tables.

Projection of Funded Status
The Retirement Funds' funding level has decreased in recent years due to a combination of factors, including: adverse market conditions and investment returns as a result of the financial downturns experienced in 2001 and in 2008 and beyond; and contributions that are lower than the Actuarially Required Contribution. With respect to MEABF and LABF, the funding level increased for fiscal year 2014 as a result of the implementation of P.A. 98-641. The manner of funding MEABF and LABF reverted to the law in effect prior to the implementation of P.A. 98-641 after the Circuit Court determined P.A. 98-641 to be unconstitutional.

The following projections (collectively, the "Projections") are based upon numerous variables that are subject to change. The Projections are forward-looking statements regarding future events based on the Retirement Funds' actuarial assumptions and assumptions made regarding such future events, including that there are no changes to the current legislative structure and that all projected contributions to the Retirement Funds are made as required. No assurance can be given that these assumptions will be realized or that actual events will not cause material changes to the data presented in this subsection.
The Projections are based on data as of December 31, 2014, and are provided to indicate expected trends in the funded status ofthe Retirement Funds under the applicable law. The Projections provided in this section with respect to MEABF combine pension and OPEB liabilities together in a single projection, whereas the Projections included with respect to the other Retirement Funds exclude OPEB liabilities. The Projections reflect the implementation of both P.A. 96-1495 and P.A. 98-641. However, P.A. 98-641 has been determined to be unconstitutional by the Circuit Court. For projections regarding MEABF and LABF under the law in effect prior to the enactment of P.A. 98-641, see "—Effect on MEABF and LABF if P.A. 98-641 Found Unconstitutional" herein. In addition, the Projections do not consider the potential impact of SB 777 or any similar legislation impacting the P.A. 96-1495 Funding Plan.

Aggregate data presented in this table includes data for all four Retirement Funds.
Represents contributions expected to be made by the City during the fiscal year.

The projections in Tables 15 and 16 show that the assets of both FABF and PABF will, under current law, begin to increase in 2016. This increase assumes the implementation of the P.A. 96-1495 Funding Plan. This projection does not consider the impact of any bill delaying the impact of P.A. 96-1495, such as SB 777. See "—Determination of City's Contributions—City's Required Contributions to PABF and FABF Beginning in 2016" herein. The City projects that, should such a delay bill be enacted, the purpose of such bill would be to alleviate the strain of the contributions currently projected to occur pursuant to P.A. 96-1495, which would most likely have the effect of delaying the increases in the Funded Ratio with respect to such Retirement Funds during the period in which the contributions

E-31

established pursuant to such delay bill are lower than those under P.A. 96-1495. See "—Determination of City's Contributions—City's Required Contributions to PABF and FABF Beginning in 2016" herein.

The statements made in this subsection are based on projections, are forward-looking in nature and are developed using assumptions and information currently available. Such statements are subject to certain risks and uncertainties. The projections set forth in this Appendix rely on information produced by the Retirement Funds' independent actuaries (except where specifically noted otherwise) and were not prepared with a view toward complying with the guidelines established by the American Institute of Certified Public Accountants with respect to prospective financial information. This information is not fact and should not be relied upon as being necessarily indicative of future results. Readers of this Appendix are cautioned not to place undue reliance on the prospective financial information. Neither the City, the City's independent auditors, nor any other independent accountants have compiled, examined, or performed any procedures with respect to the prospective financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, the prospective financial information.
Legislative Changes
P.A. 96-0889
On April 14, 2010, then Governor Quinn signed Public Act 96-0889 (the "Pension Reform Act") into law. The Pension Reform Act establishes a "two-tier" benefit system with less generous benefits for employees who become members of MEABF and LABF on or after January 1, 2011 ("Tier II Members") as compared to those provided to employees prior to such date ("Tier I Members"). The Pension Reform Act does not impact persons who first became employees prior to its effective date of January 1, 2011.
Among other changes, the Pension Reform Act: (i) increases the minimum age at which an employee may retire with unreduced benefits to age 67 from age 60 or younger based on a formula combining the age of the employee and the number of years of service; (ii) increases the minimum age at which an active employee may retire with reduced benefits to age 62 from age 50; (iii) provides that final average salary is based on 96 consecutive months within the last 120 months of employment (instead of 48 months ofthe last 120 months); (iv) reduces the annual cost of living adjustment to the lower of 3 percent or 50 percent of the change in the consumer price index for all urban consumers, whichever is lower, and eliminates compounding for employees hired after January 1, 2011, compared with a cost of living adjustment of 3 percent, compounded, under prior law; and (v) caps the salary on which a pension may be calculated at $106,800 (subject to certain adjustments for inflation).
The Pension Reform Act as described in this subsection, taken independently of any other legislative or market effects, is expected to reduce benefits afforded new hires and therefore reduce over time the growth in the Actuarial Accrued Liability, the UAAL and the Actuarially Required Contribution for MEABF and LABF. In calculating the Actuarial Accrued Liability, the actuaries make assumptions about future benefit levels. As the value of future benefits decreases over time, and as a greater percentage ofthe City's workforce is covered by the Pension Reform Act, the Actuarial Accrued Liability is expected to decrease compared to what it would have been under previous law. Consequently, the UAAL is expected to. grow more slowly and the Funded Ratio to increase. As the growth in the UAAL slows, the Actuarially Required Contribution is expected to be reduced as the amount of UAAL to be amortized decreases. However, no assurance can be given that these expectations will be the actual experience going forward.




E-3 2

P.A. 96-1495
P.A. 96-1495 has a significant impact on PABF and FABF. Certain provisions of P.A. 96-1495 are discussed above in "—Determination of City's Contributions—City's Required Contributions to PABF and FABF Beginning in 2016." The P.A. 96-1495 Funding Plan will have the effect of significantly increasing the City's contributions to PABF and FABF because, among other things, such contributions will no longer be determined pursuant to the Multiplier Funding system and because the P.A. 96-1495 Funding Plan is designed to require larger contributions by the City. The greater contributions projected to be required under the P.A. 96-1495 Funding Plan are expected to pose a substantial burden for the City's financial condition beginning in 2016. See "—Projection of Funded Status" above.
In addition, P.A. 96-1495 makes changes to benefits for police officers and firefighters first participating in PABF and FABF on or after January 1, 201 1. Among other changes, P.A. 96-1495: (i) increases the minimum eligibility age for unreduced retirement benefits from 50 (with ten years of service) to 55 (with ten years of service); (ii) provides for retirement at age 50 (with ten years of service) with the annuity reduced by 0.5 percent per month; (iii) provides that final average salary is based on 96 consecutive months within the last 120 months of employment (instead of 48 months of the last 120 months); (iv) reduces the cost of living adjustment to the lower of 3 percent or 50 percent of the change in the consumer price index for all urban consumers ('"CPI-u"), whichever is lower, commencing at age 60; (v) provides that widow benefits are 66 2/3 percent of the employee's annuity at the date of death; and (vi) caps the salary on which a pension may be calculated at $106,800 (subject to certain adjustments for inflation).

While the reforms discussed in this sub-section are expected to contribute to a reduction in the respective UAALs of PABF and FABF over time, such reforms are not expected to materially reduce such UAALs in the near future.
P.A. 98-641
If determined by the Illinois Supreme Court to be consitutional, P.A. 98-641 would make significant changes to LABF and MEABF. Certain provisions relating to the. City's contributions to LABF and MEABF under P.A. 98-641 are discussed above in "—Determination of City's Contributions—City's Required Contributions to LABF and MEABF Pursuant to P.A. 98-641" The P.A. 98-641 Funding Plan would have the effect of significantly increasing the City's contributions to LABF and MEABF.

In addition, with respect to LABF and MEABF, P.A. 98-641:
Skips automatic annual increases ("AAI") in 2017, 2019 and 2025 for retired members that would otherwise be entitled to receive them and who have an annuity greater than $22,000:
Provides that members who retire after the effective date of P.A. 98-641 are not eligible to receive an AAI until one full year after they otherwise would have;
Reduces the AAI rate for Tier I Members to the lesser of 3.0 percent or 50 percent of the CPI-u, except that retirees with an annual annuity of less than $22,000 will receive at least a 1 percent AAI in each year, including in the AAI skip years described above;



E-33

Reduces for Tier II Members the minimum eligibility age for unreduced retirement benefits to 65 with 10 years of service and, for reduced retirement benefits, to age 60 with 10 years of service;
Increases employee contribution rates for both Tier I Members and Tier II Members to 9.0 percent in calendar year 2015, 9.5 percent in calendar year 2016, 10.0 percent in calendar year 2017, 10.5 percent in calendar year 2018 and 11.0 percent for calendar year 2019 and after until the respective Retirement Fund reaches a 90 percent Funded Ratio, at which point the employee contribution rate is reduced to 9.75 percent and
Institutes the Recapture Provisions with respect to MEABF and LABF.

Gabriel Roeder Smith & Company ("GRS") has prepared projections of City contributions and funded status of LABF and MEABF based on the enactment of P.A. 98-641. Such projections are based on the data, assumptions and methods used in the actuarial valuations for LABF and MEABF as of December 1, 2013. Tables 18 and 19 provide such projections as compared to projected results under current Pension Code provisions.

P.A. 98-641 would also provide that the Retirement Board of LABF or MEABF may bring a mandamus action to compel the City to make the contributions required by the Pension Code, in addition to other remedies that may be available by law. P.A. 98-641 would further provide that the court may order a reasonable payment schedule to enable the City to make payments without imperiling the City's public health, safety, or welfare.

Under P.A. 98-641, such payments are expressly subordinated to the payment of the principal, interest, premium, if any, and other payments on or related to any bonded debt obligation of the City, either currently outstanding or to be issued, for which the source of repayment or security thereon is derived directly or indirectly from any funds collected or received by the City or collected or received on behalf of the City. Per P.A. 98-641. such payments on bonded debt obligations include any statutory fund transfers or other prefunding mechanisms or formulas set forth, now or hereafter, in State law. City ordinance, or bond indentures, into debt service funds or accounts of the City related to such bonded debt obligations, consistent with the pay ment schedules associated with such obligations.
In December 2014. shortly before P.A. 98-641 was to take effect, two lawsuits were filed in the Circuit Court challenging the constitutionality of P.A. 98-641. Plaintiffs argue that P.A. 98-641 violates the Pension Clause and seek a preliminary and permanent injunction prohibiting its enforcement. The City was allowed to intervene in both lawsuits to defend the constitutionality of P.A. 98-641. On July 24, 2015, the Circuit Court entered a decision in these lawsuits determining that P.A. 98-641 is unconstitutional and void in its entirety. The City has appealed the Circuit Court's decision to the Illinois Supreme Court. The City has been defending and will continue to defend this matter vigorously.' The City can give no assurance as to the ultimate outcome of the lawsuit.
Should the Illinois Supreme Court affirm the Circuit Court's decision finding P.A. 98-641 unconstitutional, MEABF and LABF are projected to become insolvent beginning in 2026 and 2029, respectively. See "—Effect on MEABF and LABF if P.A. 98-641 Found Unconstitutional" below for additional information. Should the Circuit Court's decision regarding P.A. 98-641 be affirmed, it is not clear whether or how the unfunded status or insolvency of MEABF and LABF might be resolved or what, if any, impact such a resolution may have on the City.

Diversion of Grant Money to the Retirement Funds Under P.A. 96-1495 and P.A. 98-641
P.A. 96-1495 and, if determined to be constitutional, P.A. 98-641, allow the State Comptroller to divert State grant money intended for the City to the Retirement Funds to satisfy contribution shortfalls by the City (the "Recapture Provisions"). If the City fails to contribute to the Retirement Funds as required by the Pension Code, the City will be subject to a reallocation of grants of State funds to the City if (i) the City fails to make the required payment for 90 days past the due date, (ii) the subject Retirement Fund gives notice of the failure to the City, and (iii) such Retirement Fund certifies to the State Comptroller that such payment has not been made. Upon the occurrence of these events, the State Comptroller will withhold grants of State funds from the City in an amount not in excess of the delinquent payment amount in the following proportions: (i) in fiscal year 2016, one-third of the City's State grant money, (ii) in fiscal year 2017, two-thirds of the City's State grant money, and (iii) in fiscal year 2018 and in each fiscal year thereafter, 100 percent of the City's State grant money. Should the Recapture Provisions in either of P.A. 96-1495 or, if determined to be constitutional, P.A. 98-641, be invoked as a result of the City's failure to contribute all or a portion of its required contribution, a reduction in State grant money may have a significant adverse impact on the City's finances.

Effect on MEABF and LABF If P.A. 98-641 Found Unconstitutional
As described in "—Legislative Changes—P.A. 98-641" above, P.A. 98-641 has been determined to be unconstitutional by the Circuit Court. If the Circuit Court's decision regarding the constitutionality of P.A. 98-641 is not overturned and the law in effect at the time of the enactment of P.A. 98-641 is effective, the City's consulting actuaries project that MEABF and LABF will not have assets on hand to make payments to beneficiaries beginning in 2026 and 2029, respectively. Tables 20 and 21 provide current projections of the Actuarial Accrued Liability, Market Value of Assets, UAAL, Funded Ratio and Employer Contribution with respect to MEABF and LABF in the absence of P.A. 98-641. Table 22 combines the projections in Tables 20 and 21 with the projections in Tables 15 and 16 for FABF and PABF, respectively, to provide an aggregate projection of Actuarial Accrued Liability, Market Value of Assets, UAAL, Funded Ratio and Employer Contribution for the four Retirement Funds in the absence of P.A. 98-641.

Aggregate data presented in this table includes data for all four Retirement Funds.
Represents contributions expected to be made by the City during the fiscal year.
The City cannot predict the impact that the insolvency of MEABF or LABF would have on its contributions to these Retirement Funds. Under the current provisions of the Pension Code, the City would revert to contributing the Multiplier Funding amount to MEABF and LABF. The contributions calculated pursuant to Multiplier Funding most likely would be insufficient to make all necessary payments to beneficiaries. One possibility upon insolvency of MEABF or LABF would be changes in the Pension Code to provide for pay-as-you-go funding. Under pay-as-you-go funding, the employer contribution equals the amount necessary, when added to other income, specifically employee


E-3 9

contributions, to fund the current year benefits to be paid by the retirement fund. GRS projects that, should the City be required to adopt pay-as-you-go funding to ensure that payments to beneficiaries are made to MEABF and LABF beneficiaries following the insolvency of such Retirement Funds, the City's contributions to such Retirement Funds would increase substantially. With respect to MEABF, GRS projects that pay-as-you-go funding would increase the City's contribution from approximately $208 million in 2025 to $1,107 billion in 2026, $1,607 billion in 2042 and $1,581 billion in 2060. With respect to LABF, GRS projects that pay-as-you-go funding would increase the City's contribution from approximately $21.9 million in 2028 to $99.6 million in 2029, $248 million in 2036 and $231 million in 2060. Such large increases in the City's contributions would likely have a material adverse impact on the City's financial condition.
Additionally, the City cannot predict if or when changes to the Pension Code or judicial decisions relevant to its contributions will be enacted or decided, respectively, and the impact any such legislation or judicial decisions would have on the manner in which it contributes to the Retirement Funds. Contributing pursuant to Multiplier Funding or pay-as-you-go funding, as discussed in this subsection, represent two possible outcomes; however, the City can make no representation that some other method of determining contributions, including payments that are possibly even larger than pay-as-you-go funding, would not be required.
Pension Reform
The City continues to believe that significant legislative changes, such as those applicable to MEABF and LABF under P.A. 98-641, are required to properly fund the Retirement Funds and continues to consider the options available to address the unfunded liabilities of FABF and PABF. See "— Determination of City's Contributions—City's Required Contributions to PABF and FABF Beginning in 2016" herein. Based on its work in developing pension reform proposals and other analysis, the City believes that the unfunded liabilities of FABF and PABF and, if P.A. 98-641 is finally determined to be unconstitutional, MEABF and LABF, cannot be adequately and practically addressed through increases in the City's contributions alone. If the City attempted to fund such increased contributions through an increase in taxes, the increase would be larger than any increase in recent history, politically difficult to enact, and harmful to the City's financial condition and, likely, its economy. If the City attempted to fund such increased contributions through expenditure cuts, essential City services, including, but not limited to, public health and safety, would be jeopardized. Furthermore, the amount that could be derived from the sale of City assets would be inconsequential when compared to the Retirement Funds' unfunded liabilities. Finally, a combination of revenue increases and expenditure cuts likely would not be practical to address the unfunded liabilities, given their magnitude. This is true both when considering the Retirement Funds on their own, and when viewed collectively with the unfunded liabilities of the Other Retirement Funds, whose sponsoring Governmental Units have tax bases that overlap with the City's tax base. See "—Background Information Regarding the Retirement Funds—Overlapping Taxing Bodies."

No assurance can be given that further legislation addressing the needs of FABF and PABF, and if P.A. 98-641 is finally determined to be unconstitutional, MEABF and LABF, will be enacted and no assurance can be given that such legislation, if adopted, will be upheld upon a legal challenge.

Report and Recommendations of the Commission to Strengthen Chicago's Pension Funds

The information contained in this subsection describing the CSCP and the Final Report (each as defined herein) relies on information produced by the CSCP, including the Final Report. The Final Report is available at commission/CSCP Final Report Vol.l_4.30.2010.pdf; however, the content of the Final Report and such website are not incorporated herein by such reference. The City makes no representation nor

E-40

expresses any opinion as to the accuracy of the Final Report, the statements made or the information therein, some of which may be conflicting. Furthermore, information about the Final Report is being provided for historical purposes only.
On January 11, 2008, then Mayor Richard M. Daley announced the formation of the Commission to Strengthen Chicago's Pension Funds (the "CSCP"), which was composed of a broad cross-section of City officials, union leaders, pension fund executives, and business and civic professionals. The CSCP was charged with examining the Retirement Funds and recommending ways to improve the Funded Ratio of each Retirement Fund. The CSCP met several times in 2008 through 2010, and at the CSCP's final meeting on March 24, 2010, the CSCP endorsed its final report, with three commissioners dissenting. The CSCP's final report, which included letters from the dissenting commissioners, was submitted to Mayor Daley on April 30, 2010 (the "Final Report").

The CSCP's approval of the Final Report occurred before the enactment of the Pension Reform Act, P.A. 96-0889, P.A. 96-1495 and P.A. 98-641; the Final Report, accordingly, does not consider the impact of these acts on the Retirement Funds. See "—Determination of City's Contributions" above and "—Legislative Changes" above for additional information on these acts. As described below, certain of the CSCP's findings and recommendations as contained in the Final Report are addressed by these acts.
The CSCP found that the financial health of the Retirement Funds had deteriorated due to a combination of factors, including the following: increasing liabilities due to enhanced benefits (e.g., non­recurring early retirement programs that were not properly funded); inadequate contributions, which were based upon a fixed percentage of payroll and not actuarial need (i.e., the Multiplier Funding); and adverse market conditions leading to fluctuating returns on investments (in 2000-2002 and 2007-2009) which could not keep pace with growth in liabilities. P.A. 96-1495 and P.A. 98-641 address the CSCP's finding of inadequate contributions to the Retirement Funds. See "—Determination of City's Contributions" above for information on the significant increases to the City's contributions to PABF and FABF pursuant to P.A. 96-1495 and to MEABF and LABF pursuant to P.A. 98-641.

The CSCP found that due to the inadequate contributions, the Retirement Funds have had to use assets to pay current benefits, which in turn put pressure on the asset bases and Funded Ratios of the Retirement Funds.

The CSCP modeled a set of scenarios for the Retirement Funds and found that, based on the actuarial assumptions in use by the Retirement Funds and the condition of the Retirement Funds at the end of 2009, the Retirement Funds would, in the absence of substantial changes to the Retirement Funds' funding policy and/or benefit structure, deplete all assets in each of the Retirement Funds at different dates but all within twenty years of the date of the Final Report. However, the CSCP's approval of the Final Report occurred before the enactment of the Pension Reform Act, P.A. 96-1495 and P.A. 98-641, and the depletion dates as estimated in the Final Report would not have taken into account the impact of such legislation. See "—Projection of Funded Status" above for the projections based upon the current legislative structure applicable to the Retirement Funds.

The CSCP suggested that the issues related to the Retirement Funds need to be addressed as soon as possible and offered the following specific recommendations: (i) the defined benefit structure used by the Retirement Funds should remain (as opposed to a defined contribution structure); (ii) new employees should continue to become members of the Retirement Funds; (iii) the Retirement Funds should be funded on an actuarial basis; (iv) changes in the Retirement Funds for new employees, while recognized by the CSCP as undesirable, will probably be necessary; (v) contributions to the Retirement Funds should be increased and revenue sources identified; (vi) employee contributions should not exceed the value of benefits on a career basis; (vii) any provisions in current law for refunds or for alternative benefit

E-41

calculations should be reviewed to ensure that the anticipated financial results of a reform program are actually obtained; (viii) in general, no changes in the Retirement Funds should be made unless financially neutral or advantageous to the Retirement Funds, now or in the future; (ix) a variety of other reforms should be considered, including reforming potential abuses, establishing sound reciprocity with other Illinois public pensions, implementing new structures to manage investments of the Retirement Funds, and improving administration of disability claims and benefits; and (x) any reform legislation must comprehensively and simultaneously address all aspects of the pension funding program.
CSCP's recommendations were made prior to the enactment of the Pension Reform Act, P.A. 96-0889, P.A. 96-1495 and P.A. 98-641. Certain of the CSCP's recommendations, including changes in the Retirement Funds for new members, were part of the Pension Reform Act and P.A. 98-641 (with regard to MEABF and LABF) and P.A. 96-1495 (with regard to PABF and FABF).

Special Revenue and Enterprise Fund Allocation of Retirement Fund Costs
The City allocates to its special revenue and enterprise funds their share of the City's annual contribution to the Retirement Funds based upon the amount of services provided by City employees to the functions or enterprises related to or paid out of those funds. The special revenue and enterprise funds account for their allocable share of the City's contributions to the Retirement Funds as operating and maintenance expenses. For budget year 2015, the City has budgeted for the special revenue and enterprise funds to reimburse the City approximately $74 million for their allocable share of the City's pension contribution.
The allocations described in this subsection are not required by statute but represent the City's current method of allocating its pension costs. The City may alter the manner in which it allocates its pension costs to these funds at any time.
Impact of Retirement Funds' Unfunded Liability on the City's Bond Ratings
The financial health of the Retirement Funds and the projected impact of the Retirement Funds' underfunding on future contributions to be made by the City have impacted the rating agencies' determination of the City's creditworthiness. On April 1 7, 2013, Moody's Investors Service ("Moody's") issued a release (the "Release") announcing a new approach to analyzing state and local government pensions. The method of evaluating public pension plans established in the Release is intended to be a method of standardizing information among public pension plans and does not impact the City's required contributions, the value of the Retirement Funds' assets, or the liabilities owed by the Retirement Funds. The City does not endorse the method of analysis adopted by Moody's in the Release.
Moody's new pension analysis appears to include, among other things, adjusting pension plan Actuarial Accrued Liabilities by using certain common assumptions, such as the discount rate and amortization period. Certain other actuarial assumptions, such as mortality and salary growth rates, were not standardized across governmental plans. To accomplish its review, Moody's stated that it will use a discount rate based on Citibank's Pension Liability Index discount rate as of a pension plan's valuation date. Such a discount rate will be lower than the discount rate currently used by the Retirement Funds and is closer to the discount rate for a typical pension plan in the private sector. The City estimates that Moody's new method of analysis would result in the following Funded Ratios of the Retirement Funds (based on projected December 31, 2014 assets and liabilities provided in the actuarial valuations ofthe Retirement Funds as of December 31, 2013): 27.4 percent for MEABF, 43.5 percent for LABF, 18.8 percent for PABF, and 15.5 percent for FABF. See Tables 5 through 8 above for information on the Retirement Funds' historical Funded Ratios. For information regarding the Retirement Funds' discount

rate, see "—Actuarial Assumptions—Assumed Investment Rate of Return'' above. The Release can be obtained from Moody's; provided, however, that the Release is not incorporated herein by such reference.
On May 12, 2015, Moody's issued a ratings action report (the "Rating Report") downgrading the ratings of the City's general obligation bonds and sales tax revenue bonds from "Baa2" to "Bal," the City's water senior lien revenue bonds from "A2" to "Baal," the City's wastewater senior lien revenue bonds from "A3" to "Baa2," the City's water second lien revenue bonds from "A3" to "Baa2," the City's wastewater second lien revenue bonds from "Baal" to "Baa3," and placed all such ratings on negative outlook. This follows previous downgrades of the City's ratings by Moody's on February 27, 2015, March 4, 2014, and July 17, 2013. Moody's indicated in the Rating Report that the May 12, 2015 downgrades reflected the expected continued growth in the unfunded liabilities of the Retirement Funds and the narrowing of the City's options for curbing such growth as a result of the Illinois Supreme Court's decision finding the State Pension Reform Act unconstitutional. Moody's indicated that further downgrades could follow if, among other things, (i) P.A. 98-641 was found to be unconstitutional, or (ii) the Retirement Funds' UAAL continues to grow. The City makes no prediction as to whether the Moody's rating action described above will result in additional downgrades, or the impact that the financial condition of the Retirement Funds will have on Moody's or any other rating agency's judgment of the City's creditworthiness or on the City's future financing costs. The Rating Report can be obtained from Moody's; provided, however, that the report is not incorporated herein by such reference.
On May 15, 2015, Fitch Ratings, Inc. ("Fitch") downgraded the City's general obligation bond and sales tax bond ratings from "A-" to "BBB+" and placed each rating on negative watch. In announcing these ratings downgrades, Fitch cited, among other things, increased fiscal pressures as a result of the Illinois Supreme Court decision finding the State Pension Reform Act unconstitutional. Fitch further indicated that a determination that P.A. 98-641 is unconstitutional would likely lead to additional downgrades. On July 3, 2015, Fitch removed the negative watch from the City's general obligation bond and sales tax bond ratings and placed such ratings on negative outlook
On July 8, 2015, Standard & Poor's Ratings Group ("S&P") downgraded the City's general obligation bond rating from "A-" to "BBB+" with a negative outlook and removed the rating from negative watch. In downgrading the City's general obligation bond rating, S&P cited, among other things, the City's pension liabilities, the impact on the City's budget of scheduled future increases in pension contributions, and "the City's lack of progress in unveiling a sustainable funding mechanism" for PABF and FABF.

On July 7, 2015, Kroll Bond Rating Agency ("Kroll") affirmed its long term rating of "A-" with a stable outlook on the City's general obligation bonds. In its report affirming the City's rating, Kroll indicated that the budgetary pressure exerted by the funding of the Retirement Funds and the future increase in contributions to PABF and FABF under P.A. 96-1495 constitute key concerns with respect to its rating ofthe City's general obligation bonds.
In addition, other rating agencies may have established, or may establish in the future, methods for evaluating the financial health of the Retirement Funds and their impact on the City's creditworthiness that are different from the information provided in this Appendix. Further downgrades of the City's bond ratings may have a material adverse impact on the City's finances. See "INVESTMENT CONSIDERATIONS—Credit Rating Downgrades" for additional information.

PAYMENT FOR OTHER POST-EMPLOYMENT BENEFITS
General

The City and the Retirement Funds share the cost of post-employment healthcare benefits available to City employees participating in the Retirement Funds through a single-employer, defined benefit healthcare plan (the "Health Plan"), which is administered by the City. Prior to June 30, 2013, the costs of the Health Plan were shared pursuant to a settlement agreement (as amended, the "Settlement") entered into between the City and the Retirement Funds regarding the responsibility for payment of these health benefits as described below under "—The Settlement."
MEABF and LABF participants older than 55 w ith at least 20 years of service and PABF and FABF participants older than 50 with at least 10 years of service may become eligible for the Health Plan if they eventually become an annuitant. The Health Plan provides basic health benefits to non-Medicare eligible annuitants and provides supplemental health benefits to Medicare-eligible annuitants.
The City contributes a percentage toward the cost of the Health Plan for each eligible annuitant. The annuitants are responsible for contributing the difference between the cost of their health benefits and the sum of the subsidies provided by the City and the related Retirement Fund. Until June 30, 2013, annuitants who retired prior to July 1, 2005 received a 55 percent subsidy from the City, whereas annuitants retiring on or after such date received a subsidy equal to 50 percent, 45 percent, 40 percent or zero percent based on the annuitant's length of actual employment with the City pursuant to the Settlement. The Retirement Funds contributed a fixed dollar amount monthly ($65 for each Medicare-eligible annuitant and $95 for each non-Medicare eligible annuitant) for each of their annuitants. For a description of benefits after the expiration of the Settlement, see "—Status of Healthcare Benefits After the Settlement Period" herein.

The Retirement Funds' subsidies are paid from the City contribution, as provided in the Pension Code and described in "Retirement Funds—Determination of City's Contributions" above. These payments therefore reduce the amounts available in the Retirement Funds to make payments on pension liabilities. See Tables 5-9 in "Retirement Funds—Funded Status of Retirement Funds" above for Retirement Funds' statement of net assets, which incorporates the expense related to the Health Plan as part of the "Administration" line item.
The Settlement
ln 1987, the City sued the Retirement Funds asserting, among other things, that the City was not obligated to provide healthcare benefits to certain retired City employees. Certain retired employees intervened as a class in the litigation, and the Retirement Funds countersued the City. To avoid the risk and expense of protracted litigation, the City and the other parties entered into the Settlement, the terms of which have been renegotiated over time. The City contributed to the Health Plan as a result of the obligation established by the Settlement during the term of the Settlement (the "Settlement Period").

Under their respective collective bargaining agreements, which were renegotiated in 2012. certain retired PABF and FABF participants are eligible lo enroll themselves and their dependents in the City's healthcare plan for active members until they reach the age of Medicare eligibility ("Special CBA Benefit"). These members do not contribute towards the cost of coverage for this plan. PABF contributes $95 per month for these members; FABF does not contribute for these members. The Special CBA Benefit expires in 2016. at which time the City expects it will be phased out permanently.



E-44

The Settlement expired on June 30, 2013. For the status of the Health Plan after the Settlement Period, see "—Status of Healthcare Benefits After the Settlement Period" below.
City Financing of the Health Plan
The City funds its share of the Health Plan's costs on a pay-as-you-go basis. Pay-as-you-go funding refers to the fact that assets are not accumulated or dedicated to funding the Health Plan. Instead, the City contributes the amount necessary to fund its share ofthe current year costs ofthe Health Plan. See Table 24 below for a schedule of historical contributions made by the City to the Health Plan.
Actuarial Considerations
City Obligation
The City has an Actuarial Valuation completed for its contributions to the Health Plan annually. The purpose and process behind an Actuarial Valuation is described above in "Retirement Funds— Actuarial Valuation —Actuaries and the Actuarial Process." In addition, the Retirement Funds produce an Actuarial Valuation for the liability of such Retirement Fund to its retirees for the benefits provided under the Health Plan.
Although these Actuarial Valuations all refer to the liability owed for the same benefits, the results of the Retirement Funds' Actuarial Valuations differ significantly from the City's Actuarial Valuation for two reasons. First, the City's Actuarial Valuation only reflects the portion of liabilities the City owes under the Settlement. Second, the Actuarial Valuations of the City and the Retirement Funds differ because the actuarial methods and assumptions used for each purpose vary.
This Appendix addresses the funded status of the City's obligation to make payments for the Health Plan. For additional information on the amounts owed to members of the Retirement Funds for retiree healthcare benefits, see the Actuarial Valuations of the Retirement Funds, which are available as described in "Retirement Funds — Source Information" above, and Note 12 to the City's Basic Audited Financial Statements, which are available on the City's website at . cityofchicago.org/city/en/depts/fin/supp_info/comprehensive_annualfinancialstatements . html; provided, however, that the contents ofthe City's website are not incorporated herein by such reference.
Actuarial Methods and Assumptions
The Actuarial Valuation for the City's obligation to the Health Plan utilizes various actuarial methods and assumptions similar to those described in "Retirement Funds" above with respect to the Retirement Funds. The City does not use an Actuarial Method to calculate the Actuarial Value of Assets of the Health Plan because no assets are accumulated therein for payment of future benefits. As such, the Actuarial Value of Assets for the Health Plan is always zero.

The City's 2012 Actuarial Valuation ("2012 Actuarial Valuation") amortizes the City's retiree healthcare UAAL over a closed 1-year period, in order to reflect the remainder of the Settlement Period and the Special CBA Benefit that was set to expire in 2012 under collective bargaining agreements that were in place at that time. The use of a closed, 1-year period has the effect of increasing the Actuarially Required Contribution as compared to the typical 30-year open amortization period because (i) the period of time over which the UAAL will be amortized is shorter, and (ii) the amortization period is one year as opposed to repeating 30-year periods. The 2012 Actuarial Valuation employed the PUC Method to allocate the City's retiree healthcare obligations. For more information on the PUC Method, see "Retirement Funds—Actuarial Methods" above.


E-45

The City's 2013 Actuarial Valuation ("2013 Actuarial Valuation") and 2014 Actuarial Valuation (the "2014 Actuarial Valuation") amortizes the City's retiree healthcare UAAL over a closed 10-year period, in order to reflect (i) the City's extension of healthcare coverage for members that had participated in the Settlement (with such coverage varying based on retirement date), and (ii) the provision of the Special CBA Benefit. For details on the Health Plan after the Settlement Period, see "— Status of Healthcare Benefits After the Settlement Period" below. The use of a closed, 10-year period rather than a closed, 1-year period has the effect of decreasing the Actuarially Required Contribution because the period of time over which the UAAL will be amortized is longer. In addition, the 2013 Actuarial Valuation and the 2014 Actuarial Valuation employed the EAN Method, rather than the PUC Method, to allocate the City's retiree healthcare obligations. For more information on the EAN Method and the PUC Method, see "Retirement Funds—Actuarial Methods" above.

Funded Status
The following tables provide information on the financial health of the Health Plan. The Health Plan is funded on a pay-as-you-go basis, which means no assets are accumulated to pay for the liabilities of the Health Plan. As such, the Funded Ratio with respect to the Health Plan is perpetually zero.

Retiree Health Benefits Commission
The Settlement provided for the creation of the Retiree Health Benefits Commission (the "RHBC"), which was tasked with, among other things, making recommendations concerning retiree health benefits after June 30, 2013. The RHBC's members were appointed by the Mayor for terms that do not expire. The Settlement required that the RHBC be composed of experts who will be objective and fair-minded as to the interest of both retirees and taxpayers, and include a representative of the City and a representative of the Retirement Funds.
On January 11, 2013, the RHBC released its "Report to the Mayor's Office on the State of Retiree Healthcare" (the "RHBC Report"). The RHBC Report can be found on the City's website at commissionreporttothemayor.html; provided, however, that the contents of the RHBC Report and of the City's website are not incorporated herein by such reference.

The RHBC Report concluded that maintaining the funding arrangement then in place for the Health Plan was untenable, would prevent the City from continuing to provide the current level of benefits to retirees in the future, and could result in other financial consequences, such as changes to the City's bond rating and its creditworthiness. The RHBC Report presented several options for the Mayor to consider which would reduce the level of spending with respect to the Health Plan from approximately $108 million annually to between $90 million and $12.5 million annually depending on the option.
Status of Healthcare Benefits After the Settlement Period
On May 15, 2013, the City announced plans to, among other things: (i) provide a lifetime healthcare plan to employees who retired before August 23, 1989 with a contribution from the City of up to 55 percent ofthe cost of that plan; and (ii) beginning January 1, 2014, provide employees who retired on or after August 23, 1989 with healthcare benefits but with significant changes to the terms provided by the Health Plan, including increases in premiums and deductibles, reduced benefits and the phase-out of the entire Health Plan for such employees by the beginning of 2017. If the City prevails in the Lawsuit (defined below), it expects a reduction in expenses of approximately $90 to $95 million annually beginning in 2017 as a result of the phase-out of the Health Plan.






E-47

On May 30, 2013, the General Assembly passed Senate Bill 1584, which was signed into law by the Governor on June 28, 2013. Senate Bill 1584 extends the Retirement Funds' subsidies for retiree healthcare costs until such time as the City no longer provides a health care plan for annuitants or December 31, 2016, whichever comes first.
After the June 30, 2013 expiration of the Settlement, on July 5, 2013, certain participants in the Health Plan filed a motion to "re-activate" the 1987 litigation covered by the Settlement. On July 17, 2013, the Circuit Court denied that motion. On July 23, 2013, certain of the participants filed a new lawsuit, Underwood v. Chicago (the "Lawsuit"), in the Circuit Court against the City and the Trustees of each ofthe four Retirement Fund Boards, seeking to bring a class action on behalf of former and current City employees who previously contributed or now contribute to one of the four Retirement Funds.
The complaint advanced state law claims, including alleged violation of the Pension Clause, and federal law claims. The City removed the case to federal court based on the federal law claims. The federal district court dismissed the case in its entirety. As to plaintiffs' claim that the planned changes violate the Pension Clause, the district court predicted that the Illinois Supreme Court would rule in a separate case, Kanerva v. Weems ("Kanerva"), then pending before the Illinois Supreme Court that healthcare benefits are not protected by the Pension Clause. However, on July 3, 2014, the Supreme Court of Illinois issued an opinion in Kanerva determining that retiree healthcare benefits provided to State retirees are protected under the Pension Clause. The City argued on appeal to the federal appellate court that it should affirm the district court dismissal, including the state law claims, on an alternative ground. On February 25, 2015, the federal appellate court affirmed the dismissal of the federal law claims and declined to rule on the state law claims on the ground that the state law claims involved a question of State law, which it ordered returned to the Illinois state court for decision. On June 22, 2015, the City and certain ofthe defendants each filed a motion to dismiss the remaining state law claims in the Circuit Court of Cook County. Oral arguments on such motions are scheduled to be heard on November 2, 2015. The City has been defending and will continue to defend this matter vigorously. The City can give no assurance as to the ultimate outcome of the Lawsuit.
