There is hereby created outside of the State treasury a special fund to be known as the Farm Credit Payment Adjustment Fund. The State Treasurer shall be custodian of such fund. All earnings on monies in such fund shall be deposited into the Farm Credit Payment Adjustment Fund. Any applicant approved by a lender for an operating loan subject to a payment adjustment shall be eligible, upon approval by the Authority, for a payment adjustment payable by the Authority to the lender from funds in either the Farm Credit Payment Adjustment Fund or the Farm Emergency Assistance Fund, at the time the operating loan subject to such payment adjustment becomes due and payable. The Comptroller shall make payments from either the Farm Credit Payment Adjustment Fund or the Farm Emergency Assistance Fund pursuant to properly certified vouchers of the Authority. Any payment adjustment granted and paid by the Authority shall be repaid by the applicant to the Authority for deposit into the Farm Credit Payment Adjustment Fund within 5 years from the date the payment adjustment was paid. It shall be paid in equal annual installments during the five-year period with no additional interest charge and may be prepaid in whole or in part at any time. All funds remaining in the Farm Credit Payment Adjustment Fund as of July 1, 1987, or July 1 of any year thereafter shall be transferred into the General Revenue Fund.
