Amounts transferred from the city contribution reserve and the employee's contribution reserve for annuities which have been fixed, amounts deducted from an employee's salary after the age and service annuity has been fixed, and amounts transferred to this reserve from the investment and interest reserve, shall be credited to this reserve.
Age and service annuities and widow's annuities shall be charged to this reserve. Amounts refunded in accordance with Section 8-170 and Section 8-154 of this Article shall be charged to this reserve.
When an employee whose annuity was fixed or granted re-enters service before age 65, an amount determined under the provisions governing re-entry into service shall be charged to this reserve and transferred to the city contribution reserve and the employee's contribution reserve, respectively, for age and service annuity. Such amount shall be divided in said reserves in the same ratio as that in which the previous transfer from such reserve to this reserve was made.
If the wife of the employee, when he re-enters service, is the same as when the widow's annuity was fixed, an amount to be determined under the provisions governing re-entry into service shall be transferred from this reserve and credited for widow's annuity in the city contribution reserve and the employee's contribution reserve, respectively. Such credit shall be in the same ratio as that in which the previous transfer was made.
If at the end of any year the balance of the annuity payment reserve exceeds the liabilities chargeable thereto by more than 15% of the liabilities, the excess shall be transferred to the investment and interest reserve, ordinary disability reserve, expense reserve, prior service annuity reserve, and city contribution reserve, in the order named, to remove any deficiency existing in any such reserves, provided that at the end of each year such amount as may be necessary for employees of the board for service rendered prior to July 1, 1935 shall be transferred to the city contribution reserve before any transfer to any of the other reserves shall be made.
