LONG-TERM OBLIGATIONS	3.LONG-TERM OBLIGATIONS Long-Term Obligations On December 20, 2018, we amended and restated our loan agreement with First Tennessee Bank National Association, which governs our existing $50,000 unsecured revolving credit facility, to (i) renew and extend the maturity date to May 31, 2022 and make certain other conforming changes, (ii) reduce the interest rate on outstanding loans from one month LIBOR rate plus 150 basis points to one month LIBOR rate plus an applicable margin of either 1.00% or 1.25% depending on the Company’s Leverage Ratio (as such term is defined in the amended and restated master revolving credit note), which margin adjusts periodically from time to time based on changes in such Leverage Ratio, and make certain other changes to the interest rate provisions, (iii) amend the tangible net worth covenant to increase the minimum required compliance level thereunder from $130,000 to $160,000 (the Company’s tangible net worth at December 31, 2019 was approximately $246,000) and (iv) modify certain definitions and other terms thereof. The credit facility contains customary representations and warranties, events of default, and financial, affirmative and negative covenants for loan agreements of this kind. Covenants under the credit facility restrict the payment of cash dividends if the Company would be in violation of the minimum tangible net worth test or the leverage ratio test in the current loan agreement as a result of the dividend, among various restrictions. We have been in compliance with these covenants throughout 2018 and 2019. In the absence of a default, all borrowings under the credit facility bear interest at the LIBOR Rate plus 1.00% or 1.25% per annum. The Company will pay a non-usage fee under the current loan agreement at a rate per annum equal to between 0.15% and 0.35% of the unused amount of the credit facility, which fee is paid quarterly. In the absence of a default, all borrowings under the credit facility bear interest at the LIBOR Rate plus 1.00% or 1.25% per annum, depending on the leverage ratio. The Company will pay a non-usage fee under the current loan agreement at a rate per annum equal to between 0.15% and 0.35% of the unused amount of the credit facility, which fee is paid quarterly. Interest expense on the credit facility was $684, $512, and $492 for the years ended December 31, 2019, 2018, and 2017, respectively. The Company had $4,998 and $15,000, in outstanding borrowings under the credit facility at December 31, 2019 and 2018, respectively. Our French subsidiary, Jige International S.A., has an agreement with Banque Européenne du Crédit Mutuel for an unsecured fixed rate loan with a maturity date of September 30, 2020. All borrowings under this loan bear interest at 0.3% per annum. At December 31, 2019, the Company had $368 in outstanding borrowings under the loan agreement, all of which was classified as long-term obligations due within one year on the consolidated balance sheets. At December 31, 2018, the Company had $760 in outstanding borrowings under the loan agreement, of which $475 and $285 were classified as long-term obligations and long-term obligations due within one year, respectively, on the consolidated balance sheets. These borrowings are being used primarily for the purchase of land and routine repairs to the operating facilities in France. The loan agreement contains no material covenants. Interest Rate Sensitivity. Changes in interest rates affect the interest paid on indebtedness under our credit facility because the outstanding amounts of indebtedness under our credit facility are subject to variable interest rates. Under our credit facility, the non-default rate of interest is equal to the LIBOR Market Index Rate plus 1.00% or 1.25% per annum, depending on the leverage ratio (for a rate of interest of 2.76% at December 31, 2019). A one percent change in the interest rate on our variable-rate debt would not have materially impacted our financial position, results of operations or cash flows for the year ended December 31, 2019.
