(5)

(c)

(A)
each period of military service performed before January 1, 1957; and
(B)
each period of military service performed after December 31, 1956, and before the separation on which title to annuity is based, if a deposit (including interest, if any) is made with respect to such period in accordance with section 8422(e).
(2) If an employee or Member is awarded retired pay based on any period of military service, the service of the employee or Member may not include credit for such period of military service unless the retired pay is awarded—

(i)
incurred in combat with an enemy of the United States; or
(ii)
caused by an instrumentality of war and incurred in line of duty during a period of war as defined by section 1101 of title 38; or

(A)
shall be allowed credit for such service without regard to the deposit requirement under paragraph (1)(B); and
(B) shall be entitled, upon filing appropriate application therefor with the Office, to a refund equal to the difference between—
(i)
the amount deposited with respect to such period under such section 8334(j) (or prior provision), excluding interest; and
(ii)
the amount which would otherwise have been required with respect to such period under paragraph (1)(B).
(4)
(A) Notwithstanding paragraph (2), for purposes of computing a survivor annuity for a survivor of an employee or Member—
(i)
who was awarded retired pay based on any period of military service, and
(ii)
whose death occurs before separation from the service,
creditable service of the deceased employee or Member shall include each period of military service includable under subparagraph (A) or (B) of paragraph (1) or under paragraph (3). In carrying out this subparagraph, any amount deposited under section 8422(e)(5) shall be taken into account.
(B) A survivor annuity computed based on an amount which, under authority of subparagraph (A), takes into consideration any period of military service shall be reduced by the amount of any survivor’s benefits—
(i)
payable to a survivor (other than a child) under a retirement system for members of the uniformed services;
(ii)
if, or to the extent that, such benefits are based on such period of military service.
(C) The Office of Personnel Management shall prescribe regulations to carry out this paragraph, including regulations under which—
(i)
a survivor may elect not to be covered by this paragraph; and
(ii)
this paragraph shall be carried out in any case which involves a former spouse.
(5)
If, after January 1, 1997, an employee or Member waives retired pay that is subject to a court order for which there has been effective service on the Secretary concerned for purposes of section 1408 of title 10, the military service on which the retired pay is based may be credited as service for purposes of this chapter only if the employee or Member authorizes the Director to deduct and withhold from the annuity payable to the employee or Member under this subchapter an amount equal to the amount that, if the annuity payment was instead a payment of the employee’s or Member’s retired pay, would have been deducted and withheld and paid to the former spouse covered by the court order under such section 1408. The amount deducted and withheld under this paragraph shall be paid to that former spouse. The period of civil service employment by the employee or Member shall not be taken into consideration in determining the amount of the deductions and withholding or the amount of the payment to the former spouse. The Director of the Office of Personnel Management shall prescribe regulations to carry out this paragraph.
(d)
Credit under this chapter shall be allowed for leaves of absence without pay granted an employee while performing military service, or while receiving benefits under subchapter I of chapter 81. An employee or former employee who returns to duty after a period of separation is deemed, for the purpose of this subsection, to have been on leave of absence without pay for that part of the period in which that individual was receiving benefits under subchapter I of chapter 81. Credit may not be allowed for so much of other leaves of absence without pay as exceeds 6 months in the aggregate in a calendar year.
(e)
Credit shall be allowed for periods of approved leave without pay granted an employee to serve as a full-time officer or employee of an organization composed primarily of employees (as defined by section 8331(1) or 8401(11)), subject to the employee arranging to pay, through the employee’s employing agency, within 60 days after commencement of such leave without pay, amounts equal to the retirement deductions and agency contributions which would be applicable under sections 8422(a) and 8423(a), respectively, if the employee were in pay status. If the election and all payments provided by this subsection are not made, the employee may not receive credit for the periods of leave without pay, notwithstanding the third sentence of subsection (d).
(f)
(1)
An employee or Member who has received a refund of retirement deductions under subchapter III of chapter 83 with respect to any service described in subsection (b)(2) or (b)(3) may not be allowed credit for such service under this chapter unless such employee or Member deposits an amount equal to 1.3 percent of basic pay for such service, with interest. A deposit under this paragraph may be made only with respect to a refund received pursuant to an application filed with the Office before the date on which the employee or Member first becomes subject to this chapter.
(2)
An employee or Member may not be allowed credit under this chapter for any service described in subsection (b)(3) for which retirement deductions under subchapter III of chapter 83 have not been made, unless such employee or Member deposits an amount equal to 1.3 percent of basic pay for such service, with interest.
(3)
Interest under paragraph (1) or (2) shall be computed in accordance with paragraphs (2) and (3) of section 8334(e) and regulations prescribed by the Office.
(4)
For the purpose of survivor annuities, deposits authorized by the preceding provisions of this subsection may also be made by a survivor of an employee or Member.
(g) Any employee who—
(1)
served in a position in which the employee was excluded from coverage under this subchapter because the employee was covered under a retirement system established under section 10 of the Federal Reserve Act; and
(2)
transferred without a break in service to a position to which the employee was appointed by the President, with the advice and consent of the Senate, and in which position the employee is subject to this subchapter,
shall be treated for all purposes of this subchapter as if any service that would have been creditable under the retirement system established under section 10 of the Federal Reserve Act was service performed while subject to this subchapter if any employee and employer deductions, contributions or rights with respect to the employee’s service are transferred from such retirement system to the Fund.
(h)
An employee or Member shall be allowed credit for service as a volunteer or volunteer leader under part A of title VIII of the Economic Opportunity Act of 1964, as a full-time volunteer enrolled in a program of at least 1 year’s duration under part A, B,1 or C of title I of the Domestic Volunteer Service Act of 1973, or as a volunteer or volunteer leader under the Peace Corps Act performed at any time prior to the separation on which the entitlement to any annuity under this subchapter is based if the employee or Member has made a deposit with interest, if any, with respect to such service under section 8422(f).
(i)
 [2] For purposes of subsection (b)(5), the term “Bank Plan” means the benefit structure in which employees of the Board of Governors of the Federal Reserve System appointed on or after January 1, 1984, participate, which benefit structure is a component of the Retirement Plan for Employees of the Federal Reserve System, established under section 10 of the Federal Reserve Act (and any redesignated or successor version of such benefit structure, if so identified in writing by the Board of Governors of the Federal Reserve System for purposes of this chapter).
(i)
(1) 2 Upon application to the Office of Personnel Management, any individual who was an employee on the date of enactment of this paragraph, and who has on such date or thereafter acquired 5 years or more of creditable civilian service under this section (exclusive of service for which credit is allowed under this subsection) shall be allowed credit (as service as a congressional employee) for service before December 31, 1990, while employed by the Democratic Senatorial Campaign Committee, the Republican Senatorial Campaign Committee, the Democratic National Congressional Committee, or the Republican National Congressional Committee, if—
(A)
such employee has at least 4 years and 6 months of service on such committees as of December 31, 1990; and
(B)
such employee deposits to the Fund an amount equal to 1.3 percent of the base pay for such service, with interest.
(2)
The Office shall accept the certification of the President of the Senate (or the President’s designee) or the Speaker of the House of Representatives (or the Speaker’s designee), as the case may be, concerning the service of, and the amount of compensation received by, an employee with respect to whom credit is to be sought under this subsection.
(3)
An individual shall not be granted credit for such service under this subsection if eligible for credit under section 8332(m) for such service.
(k)
(1)
 [3] The Office of Personnel Management shall accept, for the purposes of this chapter, the certification of the head of a nonappropriated fund instrumentality of the United States concerning service of the type described in subsection (b)(6) that was performed for such nonappropriated fund instrumentality.
(2)
Service credited under subsection (b)(6) may not also be credited under any other retirement system provided for employees paid from nonappropriated funds of a nonappropriated fund instrumentality.
(l)
(1)
Notwithstanding any other provision of this chapter, the service of an individual finally convicted of an offense described in paragraph (2) shall not be taken into account for purposes of this chapter, except that this sentence applies only to service rendered as a Member (irrespective of when rendered). Any such individual (or other person determined under section 8424(d), if applicable) shall be entitled to be paid so much of such individual’s lump-sum credit as is attributable to service to which the preceding sentence applies.
(2) An offense described in this paragraph is any offense described in section 8332(o)(2)(B) for which the following apply:

Every act or omission of the individual (referred to in paragraph (1)) that is needed to satisfy the elements of the offense occurs while the individual is a Member, the President, the Vice President, or an elected official of a State or local government.
(B)
Every act or omission of the individual that is needed to satisfy the elements of the offense directly relates to the performance of the individual’s official duties as a Member, the President, the Vice President, or an elected official of a State or local government.
(C)
The offense is committed after the date of enactment of this subsection.
(3)
An individual convicted of an offense described in paragraph (2) shall not, after the date of the final conviction, be eligible to participate in the retirement system under this chapter while serving as a Member.
(4) The Office of Personnel Management shall prescribe any regulations necessary to carry out this subsection. Such regulations shall include—
(A)
provisions under which interest on any lump-sum payment under the second sentence of paragraph (1) shall be limited in a manner similar to that specified in the last sentence of section 8316(b); and
(B) provisions under which the Office may provide for—
(i)
the payment, to the spouse or children of any individual referred to in the first sentence of paragraph (1), of any amounts which (but for this clause) would otherwise have been nonpayable by reason of such first sentence, subject to paragraph (5); and
(ii)
an appropriate adjustment in the amount of any lump-sum payment under the second sentence of paragraph (1) to reflect the application of clause (i).
(5)
Regulations to carry out clause (i) of paragraph (4)(B) shall include provisions to ensure that the authority to make any payment under such clause to the spouse or children of an individual shall be available only to the extent that the application of such clause is considered necessary and appropriate taking into account the totality of the circumstances, including the financial needs of the spouse or children, whether the spouse or children participated in an offense described in paragraph (2) of which such individual was finally convicted, and what measures, if any, may be necessary to ensure that the convicted individual does not benefit from any such payment.
(6) For purposes of this subsection—
(A)
the terms “finally convicted” and “final conviction” refer to a conviction (i) which has not been appealed and is no longer appealable because the time for taking an appeal has expired, or (ii) which has been appealed and the appeals process for which is completed;
