(a) Corporation billing and report services. Pursuant to the federal act, each lender must submit to the secretary such reports as he may require and must prepare and submit billings for the payment of federal interest subsidies and special allowances due the lender on loans held by the lender when the federal act provides for their payment by the United States on behalf of borrowers during the in-school, grace, and deferment periods of time. The corporation is not required but is authorized, pursuant to its regulations and the terms of an agreement between it and a lender but subject to any limitations imposed by the federal act, to prepare, without charge to the lender, the lender's periodic billings for federal interest subsidies and special allowances due on loans held by the lender and to submit them on behalf of the lender to the secretary for payment by the United States directly to the lender or to the corporation for and on behalf of the lender; and it is further authorized, but not required, to prepare and submit on behalf of lenders any statistical type of report required of lenders by the secretary. Interest billings and reports prepared and submitted on behalf of a lender pursuant to this Code section shall be prepared on the basis of individual borrower account records of the lender, as reflected on the records of the corporation as a result of loan transaction data reported to the corporation by the lender, but without warranty by or liability therefor of the corporation. A copy of each interest billing submitted to the secretary on behalf of a lender, including a copy of the corporation's computation of interest and allowances due the lender and the lender's loan transaction and account data on which the computation is made, shall be furnished to the lender upon payment thereof; and the lender shall be responsible therefor. It shall be the duty of each such lender to audit the copies for completeness and accuracy, post payments received to its records, and to report any correction of loan transaction data to the corporation so that the corporation's records can be corrected and so that any interest adjustment that needs to be made can be made on the next subsequent interest billing prepared for the lender. Any overpayment of federal interest subsidies or special allowances to a lender on behalf of a borrower by the United States or of state interest subsidies or loan discount payments by the state, and repayment thereof, shall be the responsibility of the borrower or the lender. Services provided for a lender by the corporation under this Code section are declared to be purely clerical and ministerial only and provided to the lender without charge as a convenience to the lender.

(b) Use of state funds to accelerate federal payments. In the event the United States makes the federal payments referred to in subsection (a) of this Code section to lenders through the corporation, the corporation is authorized, in order to accelerate and pay them to lenders as early as possible after the end of each calendar quarter, to use temporarily for this purpose any available state funds that have been appropriated for use by the corporation during the current fiscal year and state funds that have been appropriated for use by the authority during the current fiscal year which the authority may temporarily transfer to the corporation for use by the corporation for this purpose, pending receipt by the corporation of the payment from the United States and the transfer of such authority funds back to the authority by the corporation.
