The
Office shall, by regulation, provide for payment of the deposit required under
subsection (a) by a reduction in the annuity of the
employee or
Member. The reduction shall, to the extent practicable, be designed so that the present value of the future reduction is actuarially equivalent to the deposit required under
subsection (a), except that the total reductions in the annuity of an
employee or
Member to pay deposits required by this section shall not exceed 25 percent of the annuity computed under
section 8415 or
section 8452, including adjustments under
section 8462. The reduction required by this subsection, which shall be effective at the same time as the election under section
8416(b) and
(c) or
section 8417(b), shall be permanent and unaffected by any future termination of the marriage or the entitlement of the
former spouse. Such reduction shall be independent of and in addition to the reduction required under section
8416(b) and
(c) or
section 8417(b).
