(40 ILCS 5/9-173)
(from Ch. 108 1/2, par. 9-173)
Additional contributions and credits-all employees.
Any employee in service on July 1, 1947, may elect to make additional
contributions while in service which shall not exceed 7/13 of the sum
accumulated for age and service annuity on July 1, 1947, or at age 65 if he
attained such age prior thereto. The time and manner of making such
additional contributions shall be prescribed by the board. Concurrently
with each such additional contribution, the county shall contribute 1 and
4/10 times the additional contributions.
These contributions shall be improved at interest at the rate and in
like manner as other employee and county contributions; provided, that the
employee, while in service, may request a refund of all or any part of his
contributions, without interest, or shall have them refunded to him,
without interest, when he retires on annuity or to his widow, if and to the
extent they do not serve to increase the annuity otherwise payable to him
or his widow.
By such refund the employee or his widow surrenders and forfeits all
rights which might otherwise have accrued by virtue of any amount so
refunded, including related county contributions.
