 payable on such date. At the Company’s election, principal amounts may be drawn under the Revolving Credit Facility as Term SOFR Loans or Base Rate Loans. Term SOFR Loans bear interest at a rate equal to a variable rate of Term SOFR for the applicable interest period plus the Term SOFR applicable margin (see table above), which such margin is determined by reference to Borrower’s leverage ratio. Base Rate Loans bear interest at a rate per annum equal to the highest of (i) the rate of interest which the administrative agent announces from time to time as its prime lending rate, as in effect from time to time, (ii) the Federal Funds Rate, as in effect from time to time, plus 0.5%, (iii) the Term SOFR for a one-month tenor plus 1.0%, and (iv) 2.0%, in each case plus the Base Rate applicable margin (see table above), which such margin is determined by reference to the Company’s leverage ratio. Interest on Base Rate Loans is payable quarterly in arrears. Interest on Term SOFR Loans is payable at the end of the applicable interest period. The Company also pays a commitment fee based on the applicable percentage of undrawn commitment amounts under the Revolving Credit Facility. Debt issuance costs associated with the Revolving Credit Facility consist of fees incurred to secure the financing and are amortized over the life of the loan using a method which approximates the effective interest method.
