“(F) Trust fund.—
The term ‘Trust Fund’ means the Black Lung Disability Trust Fund established under section 9501 of the Internal Revenue Code of 1986.
“(2) Refinancing of outstanding principal of repayable advances and unpaid interest on such advances.—
“(A) Transfer to general fund.—
On the refinancing date, the Trust Fund shall repay the market value of the outstanding repayable advances, plus accrued interest, by transferring into the general fund of the Treasury the following sums:
“(i) The proceeds from obligations that the Trust Fund shall issue to the Secretary of the Treasury in such amounts as the Secretaries of Labor and the Treasury shall determine and bearing interest at the Treasury rate, and that shall be in such forms and denominations and be subject to such other terms and conditions, including maturity, as the Secretary of the Treasury shall prescribe.
“(ii) All, or that portion, of the appropriation made to the Trust Fund pursuant to paragraph (3) that is needed to cover the difference defined in that paragraph.
“(B) Repayment of obligations.—
In the event that the Trust Fund is unable to repay the obligations that it has issued to the Secretary of the Treasury under subparagraph (A)(i) and this subparagraph, or is unable to make benefit payments and other authorized expenditures, the Trust Fund shall issue obligations to the Secretary of the Treasury in such amounts as may be necessary to make such repayments, payments, and expenditures, with a maturity of 1 year, and bearing interest at the Treasury 1-year rate.

“(4) Prepayment of trust fund obligations.—
