The Public Pension Regulation Fund is created as a special fund in the State Treasury. Except as otherwise provided in the Illinois Pension Code, all money received by the Illinois Department of Insurance under the Illinois Pension Code shall be paid into the Fund. The State Treasurer promptly shall invest the money in the Fund, and all earnings that accrue on the money in the Fund shall be credited to the Fund. No money may be transferred from this Fund to any other fund. The General Assembly may make appropriations from this Fund for the ordinary and contingent expenses of the Public Pension Division of the Illinois Department of Insurance.
