(5) This subsection shall not apply to the annuity of a widow, surviving divorced wife, or surviving divorced mother who is entitled to such annuity on the basis of the provisions of section 231a(d)(1)(v) of this title.

(7) The first and, if necessary, the following time or times after January 1, 1983, that monthly insurance benefits under section 202 of the Social Security Act [42 U.S.C. 402] are increased, that portion of the annuity of a survivor of a deceased individual as is determined under subdivisions (1) and (2) of this subsection, or under this subsection as in effect before amendment by section 1119(g) of Public Law 97-35, shall, if such survivor’s annuity under section 231a(d) of this title began to accrue before the effective date of such first increase under the Social Security Act [42 U.S.C. 301 et seq.], be reduced by the dollar amount by which that portion of the annuity provided such survivor under subsection (f) of this section was increased, after any reduction under subsection (i) of this section, as a result of such increase or increases under the Social Security Act until the total dollar amount of such reduction or reductions equals 5 per centum of the annuity amount provided such survivor under subsection (f), as reduced under subsection (i), prior to such first increase. In no case shall the reduction by reason of this paragraph operate to reduce such portion to an amount less than $10.

(8) That portion of the annuity of a survivor of a deceased individual as is determined under subdivisions (1) and (2) of this subsection shall, if the annuity of such survivor is not subject to reduction under subdivision (7) of this subsection, be reduced by an amount equal to the dollar amount by which the annuity of the deceased individual was reduced under section 231b(g)(2) of this title or would have been reduced under such section 231b(g)(2) of this title if such deceased individual had been living at the time such survivor’s annuity under section 231a(d) of this title began to accrue (deeming for this purpose, if such individual died before becoming entitled to an annuity under section 231a(a)(1) of this title, that such individual became entitled to an annuity under paragraph (i) of such section 231a(a)(1) of this title in the month in which such individual died). In a case where the survivor of a deceased individual is not entitled to a monthly insurance benefit under the Social Security Act [42 U.S.C. 301 et seq.], the reduction provided by the preceding sentence of this subdivision shall be equal to the dollar amount by which the annuity of the deceased individual would have been reduced under section 231b(g)(2) of this title if the annuity of such deceased individual had not been subject to reduction under section 231b(m) of this title. In no case shall the reduction by reason of this paragraph operate to reduce such portion to an amount less than $10.

(9) That portion of the annuity of a survivor of a deceased individual as is determined under this subsection as in effect before amendment by section 1119(g) of Public Law 97-35 shall, if the annuity of such survivor is not subject to reduction under subdivision (7) of this subsection, be reduced by an amount equal to the dollar amount by which the annuity of the deceased individual was reduced under section 231b(g)(2) of this title or, if such survivor is not entitled to a monthly insurance benefit under the Social Security Act [42 U.S.C. 301 et seq.], would have been reduced under such section 231b(g)(2) of this title if the annuity of such deceased individual had not been subject to reduction under section 231b(m) of this title. In no case shall the reduction by reason of this paragraph operate to reduce such portion to an amount less than $10.

(10)(i) If for any month the unreduced annuity provided under this section for a widow or widower is less than the widow’s or widower’s initial minimum amount computed pursuant to paragraph (ii) of this subdivision, the unreduced annuity shall be increased to that initial minimum amount. For the purposes of this subdivision, the unreduced annuity is the annuity without regard to any deduction on account of work, without regard to any reduction for entitlement to an annuity under section 231a(a)(1) of this title, without regard to any reduction for entitlement to a benefit under title II of the Social Security Act [42 U.S.C. 401 et seq.], and without regard to any reduction for entitlement to a public service pension pursuant to section 202(e)(7), 202(f)(2), or 202(g)(4) of the Social Security Act.⁵

(ii) For the purposes of this subdivision, the widow or widower’s initial minimum amount is the amount of the unreduced annuity computed at the time an annuity is awarded to that widow or widower, except that—

(A) in subsection (g)(1)(i) “100 per centum” shall be substituted for “50 per centum”; and

(B) in subsection (g)(2)(ii) “130 per centum” shall be substituted for “80 per centum” both places it appears.

(iii) If a widow or widower who was previously entitled to a widow’s or widower’s annuity under section 231a(d)(1)(ii) of this title becomes entitled to a widow’s or widower’s annuity under section 231a(d)(1)(i) of this title, a new initial minimum amount shall be computed at the time of award of the widow’s or widower’s annuity under section 231a(d)(1)(i) of this title.
