The Secretary may make supplemental payments to any civil service annuitant who is a former foreign national employee of the Service (or who is receiving an annuity as a survivor of a former foreign national employee of the Service) in order to offset exchange rate losses, if the annuity being paid such annuitant is based on—

(1) The Secretary shall establish compensation (including position classification) plans for foreign national employees of the Service and United States citizens employed under section 3951(c)(1) of this title. To the extent consistent with the public interest, each compensation plan shall be based upon prevailing wage rates and compensation practices (including participation in local social security plans) for corresponding types of positions in the locality of employment, except that such compensation plans shall provide for payment of wages to United States citizens at a rate which is no less than the then applicable minimum wage rate specified in section 206(a)(1) of title 29. Any compensation plan established under this section may include provision for (A) leaves of absence with pay for employees in accordance with prevailing law and employment practices in the locality of employment without regard to any limitation contained in section 6310 of title 5, (B) programs for voluntary transfers of such leave and voluntary leave banks, which shall, to the extent practicable, be established in a manner consistent with the provisions of subchapters III and IV, respectively, of chapter 63 of title 5, and (C) payments by the Government and employees to (i) a trust or other fund in a financial institution in order to finance future benefits for employees, including provision for retention in the fund of accumulated interest and dividends for the benefit of covered employees; or (ii) a Foreign Service National Savings Fund established in the Treasury of the United States, which (I) shall be administered by the Secretary, at whose direction the Secretary of the Treasury shall invest amounts not required for the current needs of the Fund; and (II) shall be public monies, which are authorized to be appropriated and remain available without fiscal year limitation to pay benefits, to be invested in public debt obligations bearing interest at rates determined by the Secretary of the Treasury taking into consideration current average market yields on outstanding marketable obligations of the United States of comparable maturity, and to pay administrative expenses. For United States citizens under a compensation plan, the Secretary shall define those allowances and benefits provided under United States law which shall be included as part of the total compensation package, notwithstanding any other provision of law, except that this section shall not be used to override United States minimum wage requirements, or any provision of the Social Security Act [42 U.S.C. 301 et seq.] or title 26.

The Secretary may make supplemental payments to any civil service annuitant who is a former foreign national employee of the Service (or who is receiving an annuity as a survivor of a former foreign national employee of the Service) in order to offset exchange rate losses, if the annuity being paid such annuitant is based on—

(A) a salary that was fixed in a foreign currency that has appreciated in value in terms of the United States dollar; and

(B) service in a country in which (as determined by the Secretary) the average retirement benefits being received by individuals who retired from competitive local organizations are superior to the local currency value of civil service annuities plus any other retirement benefits payable to foreign national employees who retired during similar time periods and after comparable careers with the Government.

Whenever a foreign national employee so elects during a one-year period established by the Secretary of State with respect to each post abroad, the Secretary of the Treasury (at the direction of the Secretary of State) shall transfer such employee’s interest in the Civil Service Retirement and Disability Fund to a trust or other local retirement plan certified by the United States Government under a local compensation plan established for foreign national employees pursuant to this section (excluding local social security plans).

(C) Any such transfer shall void any annuity rights or entitlement to lump-sum credit under subchapter III of chapter 83 of such title.
