Debt Instrument, Unused Borrowing Capacity, Description |  | Borrowings under the Facility bear interest, at the Company’s option, for Secured Overnight Financing Rate ("SOFR") borrowings at (i) an Adjusted Term SOFR rate (subject to a 0.00% floor), where such “Adjusted Term SOFR” rate is equal to the Term SOFR rate for the applicable interest period plus 0.10%, plus the Applicable Margin or (ii) for base rate borrowings, the greatest of (a) the prime rate, (b) the federal funds rate plus 0.50% and (c) the Adjusted Term SOFR rate (subject to a 0.00% floor) for a one-month interest period plus 1.00%, in each case plus the Applicable Margin. The “Applicable Margin” initially was 1.125% for SOFR rate borrowings and 0.125% for base rate borrowings, and after September 30, 2023, can fluctuate, determined by reference to the more favorable to the Company of its (i) public debt rating and (ii) consolidated leverage ratio, as specified in the Credit Agreement. Up to $50.0 million of the Facility may be used for letters of credit. The Credit Agreement enables the Company, from time to time, to add term loans or to increase the revolving credit commitment in an aggregate amount not to exceed $500.0 million |  |  |
