(b) Loss of subsidy upon default.--A default by an eligible borrower in repayment of an Agriculture-Linked Investment Loan shall result in the loss of the subsidy provided under this chapter, in which case the interest rate payable by the lending institution shall revert to the interest rate on deposits as established by the Board of Finance and Revenue from time to time as otherwise established by law. As used in this subsection, the term “default” means a loan which is more than 90 days in arrears on payments.
