The deposit may be made in one or more installments (including by allotment from pay), as determined by the Director.
If a participant has not paid a deposit for civilian service performed before October 1, 1982, for which retirement deductions were not made, such participants annuity shall be reduced by 10 percent of the deposit described in paragraph (1) remaining unpaid, unless the participant elects to eliminate the service involved for the purpose of the annuity computation.
A participant who received a refund of retirement contributions under this or any other retirement system for Government employees covering service for which the participant may be allowed credit under this subchapter may deposit the amount received, with interest computed under paragraph (1). Credit may not be allowed for the service covered by the refund until the deposit is made, except that a participant who

Credit toward retirement under the system shall not be allowed for any period of civilian service on the basis of which the participant is receiving (or will in the future be entitled to receive) an annuity under another retirement system for Government employees, unless the right to such annuity is waived and a deposit is made under paragraph (1) covering that period of service, or a transfer is made pursuant to subsection (c) of this section.
If an employee who is under another retirement system for Government employees becomes a participant in the system by direct transfer, the Governments contributions (including interest accrued thereon computed in accordance with section 8334 (e) of title 5) under such retirement system on behalf of the employee as well as such employees total contributions and deposits (including interest accrued thereon), except voluntary contributions, shall be transferred to the employees credit in the fund effective as of the date such employee becomes a participant in the system.
Each such employee shall be deemed to consent to the transfer of such funds, and such transfer shall be a complete discharge and acquittance of all claims and demands against the other Government retirement fund on account of service rendered before becoming a participant in the system.
A participant whose contributions are transferred pursuant to paragraph (1) shall not be required to make additional contributions for periods of service for which full contributions were made to the other Government retirement fund, nor shall any refund be made to any such participant on account of contributions made during any period to the other Government retirement fund at a higher rate than that fixed for employees by section 8334 (c) of title 5 for contributions to the fund.
If a participant in the system becomes an employee under another Government retirement system by direct transfer to employment covered by such system, the Governments contributions (including interest accrued thereon computed in accordance with section 8334 (e) of title 5) to the fund on the participants behalf as well as the participants total contributions and deposits (including interest accrued thereon), except voluntary contributions, shall be transferred to the participants credit in the fund of such other retirement system effective as of the date on which the participant becomes eligible to participate in such other retirement system.
Each such employee shall be deemed to consent to the transfer of such funds, and such transfer shall be a complete discharge and acquittance of all claims and demands against the fund on account of service rendered before the participants becoming eligible for participation in that other system.
If a deposit required to obtain credit for prior military service described in subsection (a)(2) of this section was not made to another Government retirement fund and transferred under subsection (c)(1) of this section, the participant may obtain credit for such military service, subject to the provisions of this subsection and subsections (f) through (h) of this section, by applying for it to the Director before retirement or separation from the Agency.

Notwithstanding paragraph (3), the survivor annuity of a survivor of a participant
shall be computed in accordance with section 8332 (c)(3) of title 5.
Notwithstanding any other provision of this section (except paragraph (3) of this subsection) or section 2083 of this title, any military service (other than military service covered by military leave with pay from a civilian position) performed by a participant after December 1956 shall be excluded in determining the aggregate period of service on which an annuity payable under this subchapter to such participant or to the participants spouse, former spouse, previous spouse, or child is based, if such participant, spouse, former spouse, previous spouse, or child is entitled (or would upon proper application be entitled), at the time of such determination, to monthly old-age or survivors insurance benefits under section 402 of title 42, based on such participants wages and self-employment income. If the military service is not excluded under the preceding sentence, but upon attaining age 62, the participant or spouse, former spouse, or previous spouse becomes entitled (or would upon proper application be entitled) to such benefits, the aggregate period of service on which the annuity is based shall be redetermined, effective as of the first day of the month in which the participant or spouse, former spouse, or previous spouse attains age 62, so as to exclude such service.
