[1] Upfront fees of 0.5% were paid to the lenders under the New Credit Facility. The amount paid in connection with the New Term Loan is reflected as a discount on the loan and will be amortized under the effective interest method. The amount paid in connection with the New Revolver will be reflected as a reduction to the liability whenever outstanding borrowings exceed the remaining unamortized issuance costs, otherwise such amount will be reflected as an asset. The issuance cost related to the New Revolver will be amortized ratably over the life of the facility.
