Identifier	Return Reference	Explanation
Description of Intended Use of Endowment Funds:	Part V, Line 4:	The Investment Committee, which oversees all the Corporation's investments, operates under investment and spending policies for endowment assets that attempt to provide a predictable stream of funding to programs, while seeking to maintain the purchasing power of the endowment assets. Under these policies, the endowment assets are invested in a manner that, over time, will meet the long-term objective of a 5% real return on assets. The Corporation's policy is to preserve the historical dollar value of permanently restricted contributions, and to use any of the investment returns as is prudent considering the Corporation's long- and short-term needs, resources, duration and preservation of donor-restricted endowment funds, donor restrictions, expected total return on its investments, price level trends, general economic conditions, and investment policies.
Description of Uncertain Tax Positions Under FIN 48:	Part X:	Income Taxes The Corporation is exempt from federal and state income taxes under the provisions of Section 501(c)(3) of the Internal Revenue Code unless it has income from unrelated business activities. The Corporation follows the standard on accounting for uncertainty in income taxes, which addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under this guidance, the Corporation may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. Examples of tax positions include the tax-exempt status of the Corporation, continued tax exempt status of bonds payable, and various positions related to the potential sources of unrelated business taxable income. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement. The guidance on accounting for uncertainty in income taxes also addresses de-recognition classification, interest and penalties on income taxes, and accounting in interim periods. At June 30, 2011 and 2010, there were no unrecognized tax benefits identified or recorded as liabilities. The Corporation files Form 990 in the U.S. federal jurisdiction and the State of Illinois. The Corporation is generally no longer subject to examination by the Internal Revenue Service for years before 2007.
Part XI, Line 8 - Other Adjustments:		Changes in pension plan assets and benefit obligations 5,631,411. Swap market value adjustment 3,524,879.

Supplemental Information. Complete this part to provide the information required in Part I, line 2, and any other additional information.

Identifier	Return Reference	Explanation
Procedure for Monitoring Grants in the U.S.:	Part I, Line 2:	Schedule I, Part I, Line 2: All regular members of the Civic Orchestra of Chicago receive a stipend. Associate members receive stipends if they perform as a sub or an extra player. Most Regular members receive an annual stipend of $6,300. Five string players who are assigned to principal positions via audition receive an additional $2,000 per season. Stipends offset the cost of living, allowing musicians more time to spend on their music studies. While the majority of Civic musicians are post-graduates, stipends may be applied to tuition expenses for students pursuing degrees in music. Six graduate string players, all of whom are Regular members, receive a fellowship (rather than the stipend) annually that is disbursed on an annual or semester basis directly to the academic institution they are attending. This is part of a cooperative agreement between the Civic Orchestra and area schools (Northwestern University, DePaul University and Chicago College of Performing Arts at Roosevelt University) to provide two years of tuition-free graduate study. The academic institution covers the portion of the tuition that the fellowship from the Civic Orchestra does not cover.
Other Information:	Part IV:	Civic Membership: Members of the Civic Orchestra of Chicago are chosen by blind audition in February-March for the following season (September-May). Adjudicators are members of the Chicago Symphony Orchestra. Auditionees play a prepared list of orchestral excerpts and a solo work that has been selected by the CSO member, and are ranked by a number during the audition process. When the auditions are over, the numbers are placed in order and then matched with the name of the auditionee. From the list, Regular and Associate membership rosters are formed. Regular section membership is based on the number of players required in a given section on a regular basis. Subs and extras are drawn from the Associate membership roster as needed throughout the season. All ranking is guided by the artistic quality of the audition as determined by the adjudicator.

Form 990, Part VI, Section A, line 7a		At each annual meeting the fully ratified Governing Members elect regular and life trustees.
Form 990, Part VI, Section B, line 11		CSO staff prepares Form 990, and it is reviewed by our tax advisor. Staff and the tax advisor discuss and review the entire Form 990 and Form 990-T with members of the CSO Audit Committee, who review and accept it before it is filed as set forth in the Committee Authority and Responsibility section of the Audit Committee charter. At its Spring meeting, the Board of Trustees was reminded of the Audit Committee's responsibility to review and approve the annual tax returns. The 2010 Form 990 and Form 990-T were reviewed and approved at the April 30, 2012 meeting of the Audit Committee.
	Form 990, Part VI, Section B, line 12c	The CSO maintains a Conflict of Interest Policy that applies to all trustees, the Executive Committees of certain auxiliary operations operating under the CSO's bylaws, senior management and other designated staff members, and non-trustee members of Trustee committees. The Policy requires each person to whom the policy applies to complete an annual disclosure questionnaire that discloses any business or financial interest, which might reasonably be expected to give rise to a possible conflict between the interest of the CSO and the interest of such person. The Policy forbids such individuals from voting on or using their personal influence in connection with such business or financial issues. In the event the CSO does conduct business with a related party, the financial terms of those relationships are reported annually to the Audit Committee, whose members are independent per the terms of its charter. The CSO requires each non-union employee to conduct themselves in accordance with the code of Business Conduct and Ethics, approved by the Board of Trustees, and to sign an annual statement acknowledging their understanding of and compliance with the Code.
	Form 990, Part VI, Section B, line 15	The process for determining the compensation of the President included a meeting on October 12th, 2010, of the Administrative Personnel Committee, which was comprised of three independent trustees and two non-trustees. The Committee reviewed the compensation arrangements and peer benchmark data based on size of budget and scope of management responsibility.
