No amount of annuity in excess of $500 per month shall be payable to the widow of a policeman whose death results from any cause other than injury incurred in the performance of an act of duty, except as provided in Section 5-136.1.
If, when a policeman's annuity is fixed, there is to his credit, for such annuity, an amount in excess of that necessary to provide an annuity of 75% of his highest salary, 7/24 of such excess shall be refunded if the policeman is a future entrant; and if he is a present employee, there shall be refunded, a part of such excess amount proportionately equal to that part of the entire amount to his credit for such annuity purposes, which the sum that has resulted from salary deductions bears to such entire amount.

If the widow's annuity is fixed on or after January 1, 1986, no refund of excess contributions shall be made under this paragraph.
