8339(j)(3), (j)(5)(C), or (k)(2) shall deposit into the Fund an amount 
determined by the Office of Personnel Management (as nearly as may be 
administratively feasible) to reflect the amount by which the annuity 
of such individual would have been reduced if the election had been in 
effect since the date of retirement (or, if later, in the case of an

deposit or combination of deposits required under subsection (a) by a 
reduction in the annuity of the employee or Member.
    ``(2) The reduction shall, to the extent practicable, be designed 
such that the present value of the future reductions is actuarially 
equivalent to the present value of the deposit or combination of 
deposits required under subsection (a), except that the total reduction 
under this section may not exceed 25 percent of the annuity computed 
under subsections (a)-(i), (n), (p), and (q) of section 8339, adjusted

        case may be;
            ``(B) shall not be terminated on account of a change in 
        marital status or for any other reason; and
            ``(C) shall be in addition to any reduction made under 
        section 8339(j)(4) or (k)(1).

election under section 8339(j)(5)(C) or (k)(2) if--
            ``(1) the employee or Member makes such election after 
        having made an election under section 8339(k)(1); and

    ``(d) That the total amount withheld under this section from the 
annuity of an employee or Member, as of time of death or other annuity-
terminating event, is less than the amount described in subsection (a) 
(including interest) shall not affect either the entitlement of such 
employee's or Member's survivor to receive the annuity elected for such

may be) or the amount of such survivor annuity.''.
