LOng-Term Obligations Disclosure [Abstract] |
Long-term Debt [Text Block] | Long-Term Obligations Five-year Senior Secured Revolving Credit Facility ("Credit Facility") On November 8, 2017, we entered into a Credit Facility with various lenders for $150.0 million, with Wells Fargo Bank, N.A. as the administrative agent, swingline lender and issuing lender. During March 2020, as a result of market uncertainty caused by COVID-19, we preemptively borrowed $150.0 million on our Credit Facility as a conservative measure to manage any potential short-term liquidity risk. In September 2020, we fully repaid the borrowings under our Credit Facility. As of June 30, 2021, we had no borrowings and $150.0 million of availability under the Credit Facility. Principal payments on the revolving Credit Facility are made at our discretion with the unpaid amount due at maturity. The Credit Facility matures on November 8, 2022. Interest on borrowings under the Credit Facility, at our option, is based on the Base Rate plus applicable margin or the London Interbank Offered Rate ("LIBOR") plus applicable margin, see further details in Part II, Item 8, of our 2020 Annual Report on Form 10-K. Debt Covenants The Credit Facility contains certain financial covenants pertaining to Consolidated Fixed Charge Coverage and Consolidated Total Leverage Ratios. In addition, the Credit Facility has restrictions pertaining to limitations on debt, liens, negative pledges, loans, advances, acquisitions, other investments, dividends, distributions, redemptions, repurchases of equity interests, fundamental changes and asset sales and other dispositions, prepayments, redemptions and purchases of subordinated debt and other junior debt, transactions with affiliates, dividend and payment restrictions affecting subsidiaries, changes in line of business, fiscal year and accounting practices and amendment of organizational documents and junior debt documents. The Consolidated Leverage Ratio is defined as the ratio of Consolidated Total Funded Indebtedness on such date, to Consolidated Adjusted EBITDA, as defined under the Credit Facility Agreement, for the most recently completed four fiscal quarters. The maximum Consolidated Leverage Ratio is not more than 3.00 to 1.00. The Consolidated Fixed Charge Coverage Ratio is defined as the ratio of: (a) Consolidated Adjusted EBITDA less the sum of (i) capital expenditures, (ii) federal, state, local and foreign income taxes paid in cash and (iii) cash restricted payments made after the closing date, to (b) Consolidated Fixed Charges for the most recently completed four fiscal quarters, calculated on a pro forma basis. The minimum Consolidated Fixed Charge Coverage Ratio is 2.00 to 1.00. We were in compliance with all financial covenants as of June 30, 2021.
