SECTION 1. CREDITABILITY OF SERVICE.

    Section 8332 of title 5, United States Code, is amended by adding 
at the end the following:
    ``(o)(1) Upon application to the Office of Personnel Management, 
any employee or Member shall be allowed credit for service performed, 
after December 31, 1965, and before January 1, 1987, as an employee 
described in section 2105(c), but only if that individual has completed 
or thereafter completes at least 5 years of creditable civilian service 
under this section (exclusive of service for which credit is allowed 
under this subsection).
    ``(2)(A) Except as provided in subparagraph (C), credit for a 
period of service shall not be allowed under this subsection unless the 
employee or Member deposits to the credit of the Fund an amount equal 
to the deductions from pay which would have been required under section 
8334 with respect to such service if such employee or Member had been 
subject to this subchapter at the time of performing such service.
    ``(B) An employee or Member who makes the deposit shall be allowed 
full retirement credit for the period or periods of service involved. 
If the employee or Member dies, a survivor as defined by section 
8331(10) may make the deposit.
    ``(C) If the deposit is not made in full, retirement credit shall 
be allowed, but the annuity shall be reduced in a manner similar to 
that described in section 8418(b). In no event shall the resulting 
annuity be less than would be the case if this subsection had not been 
enacted.
    ``(3) The Office shall accept the certification of the head of the 
relevant nonappropriated fund instrumentality of the United States 
concerning the service of, and the amount of compensation received by, 
an employee or Member with respect to which credit is sought under this 
subsection.
    ``(4) An individual receiving credit for service for any period 
under this subsection shall not be granted credit for such service 
under any retirement system for employees of a nonappropriated fund 
instrumentality.
    ``(5) The Office shall prescribe regulations for the application of 
this subsection in the case of an employee or Member (within the 
meaning of chapter 84) who, upon separation, would otherwise be 
entitled to an annuity that is partially computed under this subchapter 
(determined disregarding service for which credit is allowed under this 
subsection) or a survivor of such an employee or Member.
    ``(6) An application under this subsection may be submitted no 
later than 2 years after the effective date of regulations which the 
Office shall prescribe to carry out this subsection.''.
