If the Board of Underwriters of any such city, village or incorporated town, at any time after creating a pension fund as provided in the Fire Insurance Patrolmen's Pension Fund Act of the Illinois Municipal Code or this Division shall discontinue the operation or sustaining of a paid fire insurance patrol and shall thereafter determine that there is, and if in fact there is, no person entitled to receive a benefit, pension or payment thereunder, and that there is no person eligible to receive, or who may become eligible in the future to receive such benefit, pension or payment thereunder, then the Board of Underwriters, with the consent of the Board of Trustees of the patrolmen's pension fund, may terminate the pension fund.
Thereupon the treasurer of the pension fund, upon the order of the Board of Trustees, shall refund and pay to all members of the uniformed force of the firemen's insurance patrol in the service at the time of such discontinuance of the operation or sustaining of such fire insurance patrol, from the pension fund, such sums of money as they have actually contributed to the pension fund, if there shall then be sufficient money in the fund to pay the same.
If there be not sufficient money then in the fund to make refund of such payments in full, then such reimbursement shall be made to each of such members in such equal proportion as the funds available shall be sufficient to make. After such refund of all such payments has been made as aforesaid, all moneys, securities and property of every kind in or belonging to the pension fund shall be turned over to the Board of Underwriters, as and to become the sole property of the Board of Underwriters, for its own sole use and benefit.
