| Description of borrowings on variable rate basis |
|
Borrowings under each portion of the Credit Facility bear interest at a base rate or at the London interbank market for the interest period relevant to such borrowings (“LIBOR”), as elected by SCA, plus an applicable margin. The base rate is determined by reference to the higher of (i) the prime rate of JPMorgan Chase Bank, N.A. and (ii) the federal funds effective rate plus 0.50%. The LIBOR rate is determined by reference to the interest rate for dollar deposits in the London interbank market for the interest period relevant to such borrowings. Interest payments, along with the installment payments of principal, are made at the end of each quarter. |
