Covenant description     Under the Credit Agreement, there are various restrictive covenants, including two financial covenants which limit the consolidated total leverage ratio, or leverage ratio, the consolidated interest coverage ratio, or interest coverage ratio, which, after the Third Amendment, only applies if our cash and cash equivalents balance is less than $450 million as of the last day of any fiscal quarter. The leverage ratio is the ratio of net debt as of the measurement date to Consolidated EBITDA, for the four consecutive quarters ending with the quarter of measurement. The current leverage ratio shall not exceed 3.75 to 1.00 provided that for the four fiscal quarters ending after the date of a material acquisition, such maximum leverage ratio shall be adjusted to 4.25 to 1.00, and thereafter 3.75 to 1.0. The interest coverage ratio is Consolidated EBITDA to interest expense for the four consecutive quarters ending with the quarter of measurement. If our quarter-end cash and cash equivalents balance is less than $450.0 million, the interest coverage ratio must not be less than 3.50 to 1.0 as of the date of determination. As of September 2023, we remain in compliance with the restrictive covenants.

Description of base rate     The Credit Agreement bears interest, at our election, of a Base Rate plus an Applicable Margin or Adjusted Term SOFR, as defined in the Second Amendment, plus an Applicable Margin. Swingline loans bear interest at a Base Rate plus an Applicable Margin. The Base Rate is a floating rate that is the greater of the Prime Rate, the Federal Funds Rate plus 50 basis points, or Adjusted Term SOFR plus 100 basis points. The Applicable Margin is based on a sliding scale which ranges from 25 to 100 basis points for Base Rate loans and 100 basis points to 175 basis points for Adjusted Term SOFR loans.
