Loans under this section shall be repayable in not more than forty years and, except for loans with final due date not longer than five years from the date of the loan, shall be amortized as to principal and interest. In setting the terms, rates, and charges, it shall be the objective of the Bank to provide the type of credit needed by eligible borrowers, at the lowest reasonable cost on a sound business basis, taking into account the cost of money to the Bank, necessary reserve and expenses of the Bank, and the technical and other assistance attributable to loans under this section made available by the Bank. The loan terms may provide for interest rates to vary from time to time during the repayment period of the loan in accordance with the rates being charged by the Bank for new loans at such times. The proceeds of a loan under this subsection may be advanced by the borrower to its members or stockholders under circumstances described in the bylaws or rules of the Bank.
Subject to section 3012(13) of this title, the Bank may guarantee all or any part of the principal and interest of any loan made by any State or federally chartered lending institution to any borrower if such loan is to an organization that would be an eligible borrower from the Bank for a direct loan and is on terms and conditions (including the rate of interest) which would be permissible terms and conditions for such a direct loan. The Bank may impose a charge for any such guarantee. No loan may be guaranteed by the Bank if the income therefrom to the lender is excluded from such lender’s gross income for purposes of chapter 1 of title 26.
Any loan guaranteed under subsection (c) shall be assignable to the extent provided in the contract of guarantee as may be determined by the Bank. The guarantee shall be uncontestable, except for fraud or misrepresentation of which the holder had actual knowledge at the time he acquired the loan. The Bank in lieu of requiring such lender to service such guaranteed loan until final maturity or liquidation, may purchase the loan for the balance of the principal and accrued interest thereon without penalty, if it determines that (1) the liquidation of the loan would result in the insolvency of the borrower or deprive the borrower of assets essential to its continued operation, and (2) the loan will be repayable with revision of the loan rates, terms, or payment periods or other conditions not inconsistent with loans made by the Bank under subsection (a) of this section, which revisions the lender or other holder of such guaranteed loan is unwilling to make.
