Long-term Debt [Text Block] | ( 7 ) Long-Term Debt Revolving Credit Facility. We have a $100.0 million revolving credit facility (the “Credit Facility”) that is used to supplement our operating cash flow and fund our working capital, capital expenditure, general corporate and growth requirements. In May 2015, we amended the Credit Facility to, among other changes, extend its maturity date from June 2, 2016 to May 13, 2020. Advances under the Credit Facility are limited to the lesser of the revolving loan commitment amount (currently $100.0 million) or a borrowing base amount that is calculated based upon a percentage of eligible receivables and inventories. As of September 30, 2017, no borrowings were outstanding on the Credit Facility, $85.4 million of borrowing capacity was available and outstanding letters of credit totaled $1.8 million. As of October 1, 2016, there were no borrowings outstanding on the Credit Facility. Interest rates on the Credit Facility are based upon ( 1 ) an index rate that is established at the highest of the prime rate, 0.50% plus the federal funds rate or the LIBOR rate plus the excess of the then-applicable margin for LIBOR loans over the then-applicable margin for index rate loans, or ( 2 ) at our election, a LIBOR rate, plus in either case, an applicable interest rate margin. The applicable interest rate margins are adjusted on a quarterly basis based upon the amount of excess availability on the Credit Facility within the range of 0.25% to 0.75% for index rate loans and 1.25% to 1.75% for LIBOR loans. In addition, the applicable interest rate margins would be increased by 2.00% upon the occurrence of certain events of default provided for under the terms of the Credit Facility. Based on our excess availability as of September 30, 2017, the applicable interest rate margins on the Credit Facility were 0.25% for index rate loans and 1.25% for LIBOR loans. Our ability to borrow available amounts under the Credit Facility will be restricted or eliminated in the event of certain covenant breaches, events of default or if we are unable to make certain representations and warranties provided for under the terms of the Credit Facility. We are required to maintain a fixed charge coverage ratio of not less than 1.10 at the end of each fiscal quarter for the twelve -month period then ended when the amount of liquidity on the Credit Facility is less than $12.5 million. In addition, the terms of the Credit Facility restrict our ability to, among other things: engage in certain business combinations or divestitures; make investments in or loans to third parties, unless certain conditions are met with respect to such investments or loans; pay cash dividends or repurchase shares of our stock subject to certain minimum borrowing availability requirements; incur or assume indebtedness; issue securities; enter into certain transactions with our affiliates; or permit liens to encumber our property and assets. The terms of the Credit Facility also provide that an event of default will occur upon the occurrence of, among other things: defaults or breaches under the loan documents, subject in certain cases to cure periods; defaults or breaches by us or any of our subsidiaries under any agreement resulting in the acceleration of amounts above certain thresholds or payment defaults above certain thresholds; certain events of bankruptcy or insolvency; certain entries of judgment against us or any of our subsidiaries, which are not covered by insurance; or a change of control. As of September 30, 2017, we were in compliance with all of the financial and negative covenants under the Credit Facility and there have not been any events of default. Amortization of capitalized financing costs associated with the Credit Facility was $65,000 in 2017 and 2016 and $89,000 in 2015. Accumulated amortization of capitalized financing costs was $4.6 million as of September 30, 2017 and $4.5 million as of October 1, 2016. We expect the amortization of capitalized financing costs to approximate the following amounts for the next five fiscal years:
Fiscal year |  | In thousands |
2018 |  | $ | 65 |
2019 |  |  | 65 |
2020 |  |  | 41 |
2021 |  |  | - |
2022 |  |  | - |
