Subsequent Events [Text Block]	Note 16 – Subsequent Events: On February 19, 2021, the Company entered into the Sixth Amended and Restated Loan and Security Agreement, by and among the Company, as borrower, City National Bank, as the arranger and administrative agent, and the lenders party thereto (the "New Loan Agreement"), which amends and restates in full the Company's 2020 Loan Agreement. The New Loan Agreement provides for a $350 million senior secured credit facility (the "New Credit Facility"), encompassing a $300 million delayed draw term loan facility (the "Delayed Draw Facility") and a $50 million revolving loan facility (the "Revolving Loan Facility"), which replaces the Company's prior $130 million delayed draw term loan facility and $35 million revolving loan facility. The New Credit Facility will mature on February 19, 2026, and borrowings thereunder will bear interest at variable rates depending on the Company's election, either at a base rate or at LIBOR, in each case, plus an applicable margin. Subject to the Company's leverage ratio, the applicable margin will vary between 0.75% and 2.25% for base rate loans and 1.75% and 3.25% for LIBOR loans. The Company has the option to borrow term loans under the Delayed Draw Facility ("Delayed Draw Term Loans") until August 19, 2023, subject to certain conditions. Commencing on August 19, 2022, the amount of any outstanding Delayed Draw Term Loans shall be repayable in equal consecutive quarterly installments equal to 1/28 of the outstanding Delayed Draw Term Loans. On August 19, 2023, the amortization will reset and the amount of any outstanding Delayed Draw Term Loans shall be repayable in equal consecutive quarterly installments equal to 1/28 of the outstanding Delayed Draw Term Loans and the remainder shall be due and payable on the maturity date. Borrowings under the New Credit Facility will be secured by substantially all of the Company's and certain of its subsidiaries' assets. The New Loan Agreement requires compliance with various covenants customary for agreements of this type, including financial covenants and negative covenants that limit, among other things, the Company and its subsidiaries' ability to incur additional debt, create or incur liens, engage in mergers or consolidations, sell, transfer or otherwise dispose of assets, make voluntary prepayments to subordinated debt, permit a change of control, pay dividends or distributions, make investments, and enter into certain transactions with affiliates. The New Loan Agreement also includes events of default customary for agreements of this type.
