(d) If an employee is reemployed by the Government of the United States or the government of the District of Columbia before the end of the period covered by payments of severance pay, the payments shall be discontinued beginning with the date of reemployment and the service represented by the unexpired portion of the period shall be recredited to the employee for use in any later computations of severance pay. For the purpose of subsection (b) (1) of this section, reemployment that causes severance pay to be discontinued is deemed employment continuous with that serving as the basis for severance pay.

(e) If the employee dies before the end of the period covered by payments of severance pay, the payments of severance pay with respect to the employee shall be continued as if the employee were living and shall be paid on a pay period basis to the survivor of the employee in accordance with section 5582(b) of this title.

(f) Severance pay under this section is not a basis for payment, and may not be included in the basis for computation, of any other type of United States or District of Columbia Government benefits. A period covered by severance pay is not a period of United States or District of Columbia Government service or employment.

(g) The Secretary of Agriculture shall prescribe regulations to effect the application and operation of this section to an individual named by subsection (a)(2)(B) of this section.

(h)(1) Severance pay under this section may not be paid to(A) a person described in paragraph (4)(A) during any period in which the person is employed in a defense nonappropriated fund instrumentality; or

(B) a person described in paragraph (4)(B) during any period in which the person is employed in a Coast Guard nonappropriated fund instrumentality.

(2)(A) Except as provided in subparagraph (B), payment of severance pay to a person referred to in paragraph (1) may be resumed upon any involuntary separation of the person from the position of employment in a nonappropriated fund instrumentality, not by removal for cause on charges of misconduct, delinquency, or inefficiency.

(B) Payment of severance pay may not be resumed under subparagraph (A) in the case of a person who, upon separation, is entitled to immediate payment of retired or retainer pay as a member or former member of the uniformed services or to an immediate annuity under

(i) a retirement system for persons retiring from employment by a nonappropriated fund instrumentality;

(ii) subchapter III of chapter 83 of this title;

(iii) subchapter II of chapter 84 of this title; or

(iv) any other retirement system of the Federal Government for persons retiring from employment with the Federal Government.

(3) Upon resumption of payment of severance pay under paragraph (2)(A) in the case of a person separated as described in such paragraph, the amount of the severance pay so payable for a period shall be reduced (but not below zero) by the portion (if any) of the amount of any severance pay payable for such period to the person by the nonappropriated fund instrumentality that is attributable to

credit for service taken into account under subsection (c) in the computation of the amount of the severance pay so resumed.

(4) Paragraph (1) applies to a person who, on or after January 1, 1987, moves without a break in service

(A) from employment in the Department of Defense that is not employment in a defense nonappropriated fund instrumentality to employment in a defense nonappropriated fund instrumentality; or

(B) from employment in the Coast Guard that is not employment in a Coast Guard nonappropriated fund instrumentality to employment in a Coast Guard nonappropriated fund instrumentality.

(5) The Secretary of Defense, in consultation with the Secretary of Transportation, shall prescribe regulations to carry out this subsection.

(C) The term "nonappropriated fund instrumentality" means a nonappropriated fund instrumentality described in section 2105(c) of this title.

(i)(1) In the case of an employee of the Department of Defense who is entitled to severance pay under this section, the Secretary of Defense or the Secretary of the military department concerned may, upon application by the employee, pay the total amount of the severance pay to the employee in one lump sum.

(2)(A) If an employee paid severance pay in a lump sum under this subsection is reemployed by the Government of the United States or the government of the District of Columbia at such time that, had the employee been paid severance pay in regular pay periods under subsection (b), the payments of such pay would have been discontinued under subsection (d) upon such reemployment, the employee shall repay to the Department of Defense (for the military department that formerly employed the employee, if applicable) an amount equal to the amount of severance pay to which the employee was entitled under this section that would not have been paid to the employee under subsection (d) by reason of such reemployment.

(B) The period of service represented by an amount of severance pay repaid by an employee under subparagraph (A) shall be considered service for which severance pay has not been received by the employee under this section.

(C) Amounts repaid to an agency under this paragraph shall be credited to the appropriation available for the pay of employees of the agency for the fiscal year in which received. Amounts so credited shall be merged with, and shall be available for the same purposes and the same period as, the other funds in that appropriation.

(3) If an employee fails to repay to an agency an amount required to be repaid under paragraph (2)(A), that amount is recoverable from the employee as a debt due the United States.

(4) This subsection applies with respect to severance pay payable under this section for separations taking effect on or after the date of the enactment of the National Defense Authorization Act for Fiscal Year 1996 and before October 1, 1999.
