Amounts in each cushion of credit account shall accrue interest to the borrower at a rate of 5 percent per annum.
A borrower may reduce the balance of its cushion of credit account only if the amount obtained from the reduction is used to make scheduled payments on loans made or guaranteed under this chapter.
Cushion of credit payments shall be held in the Rural Electrification and Telephone Revolving Fund as a cash balance in the cushion of credit accounts of borrowers.
All cash balance amounts (obtained from cushion of credit payments, loan payments, and other sources) held by the Fund shall bear interest to the Fund at a rate equal to the weighted average rate on outstanding certificates of beneficial ownership issued by the Fund.
The Secretary shall maintain a subaccount within the Rural Electrification and Telephone Revolving Fund to which shall be credited, on a monthly basis, a sum determined by multiplying the outstanding cushion of credit payments made after October 1, 1987, by the difference (converted to a monthly basis) between the average weighted interest rate paid on outstanding certificates of beneficial ownership issued by the Fund and the 5 percent rate of interest provided to borrowers on cushion of credit payments.
The Secretary is authorized, from the interest differential sums credited this subaccount and from any other funds made available thereto, to provide grants or zero interest loans to borrowers under this chapter for the purpose of promoting rural economic development and job creation projects, including funding for project feasibility studies, start-up costs, incubator projects, and other reasonable expenses for the purpose of fostering rural development.
