Each odd numbered year, the Commission on Government Forecasting and Accountability shall analyze data submitted by the Public Pension Division of the Department of Insurance pertaining to the pension systems established under Article 3 and Article 4 of this Code. The Commission shall issue a formal report during such years, the content of which is, to the extent practicable, to be similar in nature to that required under Section 22-1003. In addition to providing aggregate analyses of both systems, the report shall analyze the fiscal status and provide forecasting projections for selected individual funds in each system. To the fullest extent practicable, the report shall analyze factors that affect each selected individual fund’s unfunded liability and any actuarial gains and losses caused by salary increases, investment returns, employer contributions, benefit increases, change in assumptions, the difference in employer contributions and the normal cost plus interest, and any other applicable factors. In analyzing net investment returns, the report shall analyze the assumed investment return compared to the actual investment return over the preceding 10 fiscal years. The Public Pension Division of the Department of Insurance shall provide to the Commission any assistance that the Commission may request with respect to its report under this Section.
