7 C.F.R. § 1735.33
After June 10, 1991, and prior to November 1, 1993, RUS made certain variable rate loans at interest rates less than 5 percent but not less than 2 percent. For those borrowers that received variable rate loans, this section describes the method by which interest rates are adjusted. The interest rate used in determining feasibility is the rate charged to the borrower until the end of the Forecast Period for that loan. At the end of the Forecast Period, the interest rate for the loan may be annually adjusted by the Administrator upward to a rate not greater than 5 percent, or downward to a rate not less than the rate determined in the feasibility study on which the loan was based, based on the borrower's ability to pay debt service and maintain a minimum TIER of 1.0. Downward and upward adjustments will be rounded down to the nearest one-half or whole percent. To make this adjustment, projections set forth in the loan feasibility study will be revised annually by RUS (beginning within four months after the end of the Forecast Period) to reflect updated revenue and expense factors based on the borrower's current operating condition. Any such adjustment will be effective on July 1 of the year in which the adjustment was determined. If the Administrator determines that the borrower is capable of meeting the minimum TIER requirements of § 1735.22(f) at a loan interest rate of 5 percent on a loan made as described in this section, then the loan interest rate shall be fixed, for the remainder of the loan repayment period, at the standard interest rate of 5 percent.
