22 U.S. Code § 4065 - Voluntary contribution account
The benefits provided by subsection (a)(2), (3), or (4) shall be actuarially equivalent in value to the payment provided for by subsection (a)(1) and shall be calculated upon such tables of mortality as may be from time to time prescribed for this purpose by the Secretary of the Treasury.
A voluntary contribution account shall be paid in a lump sum following receipt of an application therefor from a present or former participant if application is filed prior to payment of any additional annuity. If not sooner paid, the account shall be paid at such time as the participant separates from the Service for any reason without entitlement to an annuity or a deferred annuity or at such time as a former participant dies or withdraws compulsory contributions to the Fund. In case of death, the account shall be paid in the order of precedence specified in section 4055(f) of this title.
 See Amendment of Section note below.
Section 1(a) and (c) of Ex. Ord. No. 12446, Oct. 17, 1983, 48 F.R. 48443, set out as a note under section 4067 of this title, provided that the first sentence of subsection (a) of this section, applicable (i) to contributions for civilian service performed on or after the first day of Nov. 1983, (ii) to contributions for prior refunds to participants for which application is received by the employing agency on and after such first day of Nov. 1983, and (iii) to excess contributions under section 4055(h) of this title and voluntary contributions under section 4065(a) of this title from the first day of Nov. 1983, is deemed to be amended to provide that interest shall be compounded at the annual rate of 3 percent per annum through December 31, 1984, and thereafter at a rate equal to the overall average yield to the Fund during the preceding fiscal year from all obligations purchased by the Secretary of the Treasury during such fiscal year under section 4059 of this title, as determined by the Secretary of the Treasury.
