A member of the Board of Trustees serving as a member of the public and nominated and confirmed to fill a vacancy occurring during a term shall be nominated and confirmed only for the remainder of such term. An individual nominated and confirmed as a member of the public may serve in such position after the expiration of such member’s term until the earlier of the time at which the member’s successor takes office or the time at which a report of the Board is first issued under paragraph (2) after the expiration of the member’s term. The Secretary of the Treasury shall be the Managing Trustee of the Board of Trustees (hereinafter in this subchapter called the “Managing Trustee”). The Deputy Commissioner of Social Security shall serve as Secretary of the Board of Trustees. The Board of Trustees shall meet not less frequently than once each calendar year. It shall be the duty of the Board of Trustees to—

(2) Report to the Congress not later than the first day of April of each year on the operation and status of the Trust Funds during the preceding fiscal year and on their expected operation and status during the next ensuing five fiscal years;

(3) Report immediately to the Congress whenever the Board of Trustees is of the opinion that the amount of either of the Trust Funds is unduly small;

(4) Recommend improvements in administrative procedures and policies designed to effectuate the proper coordination of the old-age and survivors insurance and Federal-State unemployment compensation program; and

(5) Review the general policies followed in managing the Trust Funds, and recommend changes in such policies, including necessary changes in the provisions of the law which govern the way in which the Trust Funds are to be managed.

The report provided for in paragraph (2) of this subsection shall include a statement of the assets of, and the disbursements made from, the Trust Funds during the preceding fiscal year, an estimate of the expected future income to, and disbursements to be made from, the Trust Funds during each of the next ensuing five fiscal years, and a statement of the actuarial status of the Trust Funds. Such statement shall include a finding by the Board of Trustees as to whether the Federal Old-Age and Survivors Insurance Trust Fund and the Federal Disability Insurance Trust Fund, individually and collectively, are in close actuarial balance (as defined by the Board of Trustees). Such report shall include an actuarial opinion by the Chief Actuary of the Social Security Administration certifying that the techniques and methodologies used are generally accepted within the actuarial profession and that the assumptions and cost estimates used are reasonable. Such report shall also include an actuarial analysis of the benefit disbursements made from the Federal Old-Age and Survivors Insurance Trust Fund with respect to disabled beneficiaries. Such report shall be printed as a House document of the session of the Congress to which the report is made. A person serving on the Board of Trustees shall not be considered to be a fiduciary and shall not be personally liable for actions taken in such capacity with respect to the Trust Funds.

It shall be the duty of the Managing Trustee to invest such portion of the Trust Funds as is not, in his judgment, required to meet current withdrawals. Such investments may be made only in interest-bearing obligations of the United States or in obligations guaranteed as to both principal and interest by the United States. For such purpose such obligations may be acquired (1) on original issue at the issue price, or (2) by purchase of outstanding obligations at the market price. The purposes for which obligations of the United States may be issued under chapter 31 of title 31 are hereby extended to authorize the issuance at par of public-debt obligations for purchase by the Trust Funds. 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 a rate equal to the average market yield (computed by the Managing Trustee on the basis of market quotations as of the end of the calendar month next preceding the date of such issue) on all marketable interest-bearing obligations of the United States then forming a part of the public debt which are not due or callable until after the expiration of four years from the end of such calendar month; except that where such average market yield is not a multiple of one-eighth of 1 per centum, the rate of interest of such obligations shall be the multiple of one-eighth of 1 per centum nearest such market yield. Each obligation issued for purchase by the Trust Funds under this subsection shall be evidenced by a paper instrument in the form of a bond, note, or certificate of indebtedness issued by the Secretary of the Treasury setting forth the principal amount, date of maturity, and interest rate of the obligation, and stating on its face that the obligation shall be incontestable in the hands of the Trust Fund to which it is issued, that the obligation is supported by the full faith and credit of the United States, and that the United States is pledged to the payment of the obligation with respect to both principal and interest. The Managing Trustee may purchase other interest-bearing obligations of the United States or obligations guaranteed as to both principal and interest by the United States, on original issue or at the market price, only where he determines that the purchase of such other obligations is in the public interest.

Any obligations acquired by the Trust Funds (except public-debt obligations issued exclusively to the Trust Funds) may be sold by the Managing Trustee at the market price, and such public-debt obligations may be redeemed at par plus accrued interest.

(1) If at any time prior to January 1988 the Managing Trustee determines that borrowing authorized under this subsection is appropriate in order to best meet the need for financing the benefit payments from the Federal Old-Age and Survivors Insurance Trust Fund or the Federal Disability Insurance Trust Fund, the Managing Trustee may borrow such amounts as he determines to be appropriate from the other such Trust Fund, or, subject to paragraph (5), from the Federal Hospital Insurance Trust Fund established under section 1395i of this title , for transfer to and deposit in the Trust Fund whose need for financing is involved.

(2) In any case where a loan has been made to a Trust Fund under paragraph (1), there shall be transferred on the last day of each month after such loan is made, from the borrowing Trust Fund to the lending Trust Fund, the total interest accrued to such day with respect to the unrepaid balance of such loan at a rate equal to the rate which the lending Trust Fund would earn on the amount involved if the loan were an investment under subsection (d) (even if such an investment would earn interest at a rate different than the rate earned by investments redeemed by the lending fund in order to make the loan).

(3) (A) If in any month after a loan has been made to a Trust Fund under paragraph (1), the Managing Trustee determines that the assets of such Trust Fund are sufficient to permit repayment of all or part of any loans made to such Fund under paragraph (1), he shall make such repayments as he determines to be appropriate. (B) (i) If on the last day of any year after a loan has been made under paragraph (1) by the Federal Hospital Insurance Trust Fund to the Federal Old-Age and Survivors Insurance Trust Fund or the Federal Disability Insurance Trust Fund, the Managing Trustee determines that the OASDI trust fund ratio exceeds 15 percent, he shall transfer from the borrowing Trust Fund to the Federal Hospital Insurance Trust Fund an amount that— (I) together with any amounts transferred from another borrowing Trust Fund under this paragraph for such year, will reduce the OASDI trust fund ratio to 15 percent; and (II) does not exceed the outstanding balance of such loan. (ii) Amounts required to be transferred under clause (i) shall be transferred on the last day of the first month of the year succeeding the year in which the determination described in clause (i) is made.
