The report shall be compiled pursuant to uniform reporting standards prescribed by the Oklahoma State Pension Commission for all state retirement systems. The report shall include several relevant measures of investment value, including acquisition cost and current fair market value with appropriate summaries of total holdings and returns. The report shall contain combined and individual rate of returns of the investment managers by category of investment, over periods of time. The Board of Trustees shall include in the quarterly reports all commissions, fees or payments for investment services performed on behalf of the Board.

The report shall be submitted to the Governor, the Speaker of the House of Representatives, the President Pro Tempore of the Senate, the Oklahoma State Pension Commission and the members of the System. The annual report shall cover the operation of the System during the past fiscal year, including income, disbursements, and the financial condition of the System at the end of the fiscal year. The annual report shall also contain the information issued in the quarterly reports required pursuant to subsection G of this section as well as a summary of the results of the most recent actuarial valuation to include total assets, total liabilities, unfunded liability or over funded status, contributions and any other information deemed relevant by the Board of Trustees. The annual report shall be written in such a manner as to permit a readily understandable means for analyzing the financial condition and performance of the System for the fiscal year. In order to standardize the information and analysis of the financial condition of the System, the Board shall provide information regarding the financial and actuarial condition of the System using assumptions or requirements as hereinafter required for the report stating the condition of the System as of July 1, 2002, and for each subsequent reporting date, which information shall be contained in an appendix or addendum to the annual report. For purposes other than the reporting requirements contained in the appendix or addendum, all actuarial and economic assumptions shall be those assumptions adopted by the System in its annual actuarial valuation. The appendix or addendum shall contain a statement of the financial condition of the System:

   1. 1. Using an assumed rate of return of seven and one-half percent (7.5%), net of investment expenses, per annum, compounded annually;
   2. 2. Using an actuarial assumption regarding cost-of-living adjustments for the System of two percent (2%) annually;
   3. 3. That relies upon the use of appropriate preretirement, postretirement and disability retirement information using generational projections taken from the RP-2000 Mortality Tables, published by the Society of Actuaries;
   4. 4. Which accurately and completely summarizes all sources of system assets, other than employee contributions, which shall include, but not be limited to, the total of all employer contributions, any dedicated tax or fee revenue of whatever kind or however denominated, and the total amount of any other source of revenue which accrues to the System, other than return on investments, such as federal monies used for the purpose of making employer contributions; and
   5. 5. Using an assumption that the unfunded actuarial accrued liabilities of the System are amortized over a period of thirty (30) years, in a manner consistent with the Governmental Accounting Standards Board Statement Number 25.
9. I. The Board of Trustees shall adopt a cost of living adjustment actuarial assumption in its annual actuarial valuation report.
