Debt Disclosure [Text Block]	(13) Indebtedness On February 1, 2018, the Company, as the borrower, entered into an unsecured $70 million Amended and Restated Credit Agreement (the “Amended and Restated Credit Agreement”) with the Company’s subsidiaries (the “Subsidiary Guarantors”) and Bank of America, N.A., in its capacity as the initial lender, Administrative Agent, Swingline Lender and L/C Issuer, and certain other lenders from time to time party thereto. The Amended and Restated Credit Agreement amends and restates the Company’s prior credit agreement. The credit facilities under the Amended and Restated Credit Agreement (the “Amended and Restated Credit Facilities”) consist of a $20 million unsecured term loan and an unsecured revolving credit facility, under which the Company may borrow up to $50 million. The term loan has been paid in full. The Amended and Restated Credit Agreement matures on February 1, 2023. The proceeds borrowed pursuant to the Amended and Restated Credit Agreement may be used for general corporate purposes, as well as permitted acquisitions. The Company’s obligations under the Amended and Restated Credit Agreement are guaranteed by the Subsidiary Guarantors. The Amended and Restated Credit Agreement calls for interest of LIBOR plus a margin that ranges from 1.0% to 1.5% or, at the discretion of the Company, the bank’s prime rate less a margin that ranges from 0.25% to zero. In both cases the applicable margin is dependent upon Company performance. Under the Amended and Restated Credit Agreement, the Company is subject to a minimum fixed-charge coverage financial covenant as well as a maximum total funded debt to EBITDA financial covenant. The Amended and Restated Credit Agreement contains other covenants customary for transactions of this type, including restrictions on certain payments, permitted indebtedness and permitted investments. As of September 30, 2020, there were $0.7 million in standby letters of credit outstanding drawable as a financial guarantee on worker’s compensation insurance policies. As of September 30, 2020, the applicable interest rate was approximately 1.14%, and the Company was in compliance with all covenants under the Amended and Restated Credit Agreement. Derivative Financial Instruments The Company uses interest-rate-related derivative instruments to manage its exposure related to changes in interest rates on its variable-rate debt instruments. The Company does not enter into derivative instruments for any purpose other than cash flow hedging. Derivative financial instruments expose the Company to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk for the Company. When the fair value of a derivative contract is negative, the Company owes the counterparty and, therefore, the Company is not exposed to the counterparty’s credit risk. The Company minimizes counterparty credit risk in derivative instruments by entering into transactions with carefully selected major financial institutions based upon their credit profile. Market risk is the adverse effect on the value of a derivative instrument that results from a change in interest rates. The Company assesses interest rate risk by identifying and monitoring changes in interest rate exposures that may adversely impact expected future cash flows and by evaluating hedging opportunities. The Company’s debt obligations expose the Company to variability in interest payments due to changes in interest rates. The Company believes that it is prudent to limit the variability of a portion of its interest payments. To meet this objective, in connection with the term loan under the Amended and Restated Credit Agreement, the Company entered into a $20 million, 5-year interest rate swap agreement under which the Company receives three-month LIBOR plus the applicable margin and pays a 2.7% fixed rate plus the applicable margin. The swap agreement was established to modify the Company’s interest rate exposure by converting the interest on the term loan from a variable rate to a fixed rate to hedge against the possibility of rising interest rates during the term of the loan. As the Company repaid its term loan in full, the swap agreement no longer serves this purpose and may be canceled by the Company prior to its expiration date. The notional amount was approximately $12.1 million at September 30, 2020. The fair value of the swap as of September 30, 2020 and December 31, 2019 was approximately $(538) thousand and $(325) thousand, respectively, and is included in other liabilities on the condensed consolidated balance sheets, respectively. Changes in the fair value of the swap are recorded in other expense on the condensed consolidated statements of income and resulted in expense of zero and $362 thousand during the three- and nine-month periods ended September 30, 2020. In the same periods in 2019, change in the fair value of the swap resulted in expense of $24 thousand and $461 thousand, respectively. LIBOR The Financial Conduct Authority (the authority that regulates LIBOR) announced in 2017 that it intends to phase out LIBOR by the end of 2021. If changes are made to the method of calculating LIBOR or LIBOR ceases to exist, the Company may need to amend certain contracts, including the Amended and Restated Credit Agreement and related interest rate swap agreement, and the Company cannot guarantee what alternative rate or benchmark would be negotiated or the extent to which this would adversely affect its interest rate and the effectiveness of its interest rate hedging activity. The Company cannot assure that it will be able to amend any of these agreements in a timely manner or at all.
