Interest Rate and Fees. Borrowings under the 2008-A Credit Agreement bear interest (a) in the case of loans with an interest rate based on the applicable base rate, or the ABR, the ABR plus an applicable margin or (b) in the case of loans with an interest rate based on the eurodollar rate, or the EDR, the EDR plus an applicable margin. The applicable margin with respect to ABR borrowings is 0.50% per annum, increasing to 1.50% per annum during the Extension Period. The applicable margin with respect to EDR borrowings is 1.50% per annum, increasing to 2.50% per annum during the Extension Period. Additionally, we are subject to a 0.25% per annum fee, increasing to 0.375% per annum fee during the Extension Period, on any unused portion of the total committed facility. We are also required to pay customary agency fees.
The ABR is determined by reference to the higher of (i) the prime rate of JPMorgan Chase Bank, N.A. and (ii) the federal funds rate plus 0.50%. The EDR is determined by reference to one-month LIBOR adjusted for any Federal Reserve Bank reserve requirements. We expect that interest on loans under the 2008-A Credit Agreement will generally be based on the EDR.
