(a) Except as provided in paragraph (b) of this subsection, all separated employees who become reemployed by the City on or after January 8, 1987 become subject to the provisions of Plan A, Plan B, Plan L, or Plan Y.

(b) The following employees shall remain subject to the provisions of the plan covering them when they separated from service with the City unless they elect, in writing, on forms provided by the Board, to transfer membership to the applicable division covered by Plan A, Plan B, Plan L, or Plan Y pursuant to § 22-205 (Optional Transfer of Membership):

(c) If a reemployed member

(.1) was receiving service or disability retirement benefits; or

(.2) is entitled to separation service retirement benefits; or

(.3) did not withdraw the member's contributions upon separation from employment; and,

(.4) was a member of Municipal Division New, Fire Division New, Police Division New or the Elected Officials Division before reemployment which division calculated service retirement benefits for years of credited service at a rate higher than that used to calculate service retirement benefits in the member's new division,

Then the member's service retirement benefits for subsequent years of service shall be calculated and credited in accordance with the provisions governing the member's new division while service retirement benefits for prior years of service shall be calculated and credited at the higher rate applicable to the member's former division in the Retirement System.

(2) Purchase of credit for prior City service. Any rehired employee who becomes a member of Plan A, Plan B, Plan L, or Plan Y pursuant to § 22-203(1) (Membership After Reemployment) and who withdrew contributions for prior service with the City may purchase credit for prior service in the member's new plan, regardless of the retirement plan to which the member had previously belonged. To purchase credit for prior service, the rehired employee must pay the amount the member contributed or would have contributed for credit if the member had been a member of Plan A, Plan B, Plan L, or Plan Y during the member's prior employment, plus interest at the assumed earnings rate for fund investments as determined by the Board from time to time. Requirements for the purchase of credit are provided in § 22-803 (Purchase of Prior City Service).
