Should any member cease to be employed as such a member, through any cause other than death or retirement or transfer to another office or department, all of his or her contributions, with interest credited thereon, shall be refunded to him or her subject to the conditions of employment and reemployment with and without redeposits of withdrawn accumulated contributions of other members of the retirement system; provided, that if such a member is entitled to be credited with accumulated contributions which exceed five hundred dollars ($500.00), he or she shall have the right to elect, without right of revocation and within ninety (90) days after such termination of service, or if the termination was by layoff, ninety (90) days after the retirement system manager determines the termination to be permanent, whether to allow his or her accumulated contributions to remain in the retirement fund. Failure to make such election shall be deemed an irrevocable election to withdraw his or her accumulated contributions unless the member is entitled to be credited with at least twenty (20) years of service. A member whose membership continues under this section is subject to the same age and disability requirements as apply to other members for service or for disability retirement but he or she is not subject to a minimum service requirement. After the qualification of such member for retirement by reason of age or disability, he or she shall be entitled to receive a retirement allowance based upon the amount of his or her accumulated contributions and service standing to his or her credit at the time of retirement and on the employer contributions held for him or her and calculated in the same manner as for other members, except that the provisions for minimum service and disability retirement allowances do not apply to him or her, unless he or she meets such minimum service requirements. Upon the death of such a member prior to retirement under this section, such death benefits as may be payable under Section 2.124.460 of this chapter shall be computed upon the basis of his or her average annual compensation earnable for the year preceding the date of termination of such service, multiplied by the years of city service prior to such termination not to exceed six.
