Debt Disclosure [Abstract] |
Debt Instrument Borrowing Base Utilization | Interest and commitment fees associated with the revolving credit facility are accrued based on a total revolving commitments utilization grid set forth in the Credit Agreement, and as presented in the table below. At the Company’s election, borrowings under the Credit Agreement may be in the form of SOFR revolving loans, Alternate Base Rate (“ABR”) revolving loans, or Swingline loans. SOFR revolving loans accrue interest at SOFR plus the applicable margin from the utilization grid, and ABR revolving loans and Swingline loans accrue interest at a market-based floating rate, plus the applicable margin from the utilization grid. Commitment fees are accrued on the unused portion of the aggregate revolving lender commitment amount at rates from the utilization grid.
