Borrowing Arrangements	6. Borrowing Arrangements The Company has credit facilities in the U.S. and Czech Republic that expire on February 2, 2019 and March 31, 2020, respectively. The Company and certain of its subsidiaries have agreed to secure all of their obligations under a credit agreement (the “Credit Agreement”) by granting a first priority lien in substantially all of their respective personal property assets (subject to certain exceptions and limitations). As of June 29, 2018, the interest rates on the outstanding Term Loan and Revolving Credit facility were 3.98% (2.0% fixed and 1.98% variable based on LIBOR) and 4.25% fixed, respectively. In order to manage interest rate risk on the variable component of the Term Loan the Company entered into an interest rate swap with the Lenders in September 2015 with a total notional amount of $20.0 million pursuant to which the Company pays the counterparty a fixed rate of 0.99% and receives interest at a variable rate equal to the LIBOR rate the Company is required to pay under its Term Loan, or 1.98%, as of June 29, 2018. This interest rate swap effectively locked in a fixed interest rate of 2.99% on $4.7 million of the $7.4 million term loan balance outstanding as of June 29, 2018, with a decreasing notional amount based on principal payments over the remaining period of the term loan. The Credit Agreement requires the Company to maintain certain financial covenants including a consolidated fixed charge coverage ratio (as defined in the Credit Agreement) of at least 1.25 to 1.00 starting with the end of the first quarter of fiscal 2015 and a consolidated leverage ratio (as defined in the Credit Agreement) no greater than 3.5 to 1.00 starting with the end of the first quarter of fiscal 2015. The Credit Agreement also includes other customary affirmative and negative covenants. In December 2015, the Credit Agreement was amended to add a covenant requiring the Company to maintain a minimum cash balance of $35.0 million at the end of each quarter. The Company was in compliance with all covenants for the quarter ended June 29, 2018. The fair value of the Company’s long term debt was based on Level 2 inputs, and fair value was determined using quoted prices for similar liabilities in inactive markets. The fair value of the Company’s outstanding borrowings under the Company’s revolving credit facility was based on Level 2 inputs, and fair value was determined using inputs other than quoted prices that are observable, specifically, discounted cash flows of expected payments at current borrowing rates. The Company’s carrying value approximates fair value for the Company’s long term debt and revolving credit facility. As of June 29, 2018, the Company had outstanding amounts under the Term Loan and Revolving Credit Facility of $7.4 million and $39.9 million, respectively, which are gross of unamortized debt issuance costs of $0.1 million, for a total debt balance with this credit facility of $47.2 million. As of June 29, 2018, FDS had outstanding amount under a revolving credit facility of 6.5 million euros (approximately $7.6 million) with an interest rate of 1.3% plus a variable rate based on the Euro Interbank Offered Rate. As of June 29, 2018, the Company’s total bank debt was $54.9 million.
