              OBLIGATIONS ISSUED TO THE SOCIAL SECURITY TRUST FUNDS.

    Section 201(d) of the Social Security Act (42 U.S.C. 401(d)) is 
amended--
            (1) by inserting ``(1)'' after ``(d)'';
            (2) by striking the fifth sentence and inserting the 
        following new sentences: ``Such obligations issued for purchase 
        by the Trust Funds shall have maturities fixed with due regard 
        for the needs of the Trust Funds and shall bear interest at an 
        effective annual rate equal to 6 percent, which shall be paid 
        to the Trust Funds semiannually. On June 30 and December 31 of 
        each calendar year, and (with respect to each obligation) on 
        its date of maturity (or date of redemption, if prior to 
        maturity), the Managing Trustee shall adjust (subject to 
        paragraph (2)) the par value of each obligation then held by 
        either of the Trust Funds and issued for purchase by such Trust 
        Fund so as to equal the product derived by multiplying the 
        current par value as of immediately before the applicable date 
        by the CPI adjustment factor (defined in paragraph (3)(A)) for 
        the obligation in connection with the month in which the 
        applicable date occurs (rounded, if not a multiple of $0.01, to 
        the nearest multiple of $0.01).''; and
            (3) by adding at the end the following new paragraphs:
    ``(2)(A) In any case in which the number of days in the actual 
adjustment period (defined in subparagraph (B)(i)) for an obligation 
differs from the number of days in the computation period (defined in 
subparagraph (B)(ii)) for the obligation, the amount by which the par 
value of an obligation is adjusted pursuant to paragraph (1) shall be 
an amount which bears the same ratio to the amount that would otherwise 
apply under paragraph (1) as the number of days in the actual 
adjustment period bears to the number of days in the computation 
period.
    ``(B) For purposes of subparagraph (A)--
            ``(i) The term `actual adjustment period' for an obligation 
        means the period beginning with--
                    ``(I) the date following the date of the last 
                previous adjustment in the par value of the obligation 
                under paragraph (1), or
                    ``(II) if no such adjustment in the par value of 
                the obligation has occurred, the date of the issuance 
                of the obligation,
        and ending with the date of the increase in par value to be 
        determined under paragraph (1).
            ``(ii) The term `computation period' for an obligation 
        means the period beginning with the date following the 
        adjustment reference month (defined in paragraph (3)(C)) for 
        the obligation and ending with the last date of the adjustment 
        computation month (defined in paragraph (3)(B)) for the 
        obligation.
    ``(3) For purposes of this subsection--
            ``(A) The term `CPI adjustment factor', for an obligation 
        in connection with any calendar month, means the ratio 
        (expressed as a percentage) of--
                    ``(i) the Consumer Price Index for the adjustment 
                computation month for the obligation in connection with 
                such calendar month to
                    ``(ii) the Consumer Price Index for the adjustment 
                reference month for the obligation in connection with 
                such calendar month.
            ``(B) The term `adjustment computation month' for an 
        obligation means, in connection with a month in which occurs 
        the date of an adjustment in par value of the obligation to be 
        determined under paragraph (1), the first of the 2 preceding 
        calendar months.
            ``(C) The term `adjustment reference month' for an 
        obligation means, in connection with a month in which occurs 
        the date of an adjustment in par value of the obligation to be 
        determined under paragraph (1)--
                    ``(i) the last adjustment computation month with 
                respect to which an adjustment in par value of the 
                obligation under paragraph (1) has occurred, or
                    ``(ii) if no such adjustment in the par value of 
                the obligation has occurred, the first of the 2 months 
                preceding the month in which such obligation was 
                issued.
            ``(D) The term `Consumer Price Index' means the Consumer
