Debt	3 Months Ended
Mar. 31, 2017
Debt Disclosure [Abstract]
Debt	Debt and Financial Instruments On December 15, 2016, we entered into a Fifth Amended and Restated Financing and Security Agreement (the “Credit Agreement”). The Credit Agreement provides for a revolving credit facility up to a maximum principal amount of $100 million expiring on December 31, 2021 and for a term loan in the principal amount of $40 million maturing on April 30, 2020. The Credit Agreement is secured by substantially all of our assets. The maximum interest rate on the Credit Agreement is the daily one-month LIBOR market index rate (for borrowings in Dollars and Sterling) or the daily one month EURIBOR (for borrowings in Euros) plus 2.50%. Based on our financial performance, the interest rate can be reduced to a minimum rate of the daily one-month LIBOR market index rate plus 1.25%, with the rate being determined based on our maximum leverage ratio for the preceding four quarters. Each unpaid advance on the revolving loan will bear interest until repaid. The term loan is payable in monthly installments of principal in the amount of $1.0 million plus applicable interest, beginning on January 1, 2017. We may prepay the term loan or the revolving loan, in whole or in part, at any time without premium or penalty, subject to certain conditions. Amounts repaid or prepaid on the term loan may not be reborrowed. The Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict our and our subsidiaries’ (subject to certain exceptions) ability to, among other things, grant liens, make investments, incur indebtedness, merge or consolidate, dispose of assets or make acquisitions. We are also required to maintain compliance with a minimum fixed charge coverage ratio and a maximum leverage ratio. We were in compliance with all of the financial covenants under the Credit Agreement as of March 31, 2017. As of March 31, 2017, our total long-term debt outstanding under the term loan was $37.0 million. In addition, there were $23.5 million of borrowings outstanding and $71.3 million of available borrowings under the Credit Agreement. For the three months ended March 31, 2017, the weighted average interest rate on our borrowings was 2.5%. Effective March 1, 2017, we entered into an interest rate swap agreement which effectively fixed our interest rate on the remaining $37 million outstanding on our term loan to a fixed LIBOR of 1.59% plus the applicable margin under the Credit Agreement. We have designated the interest rate swap, which expires on April 1, 2020, as a cash flow hedge and have applied hedge accounting. The fair value of the derivative liability associated with the interest rate swap was $0.1 million as of March 31, 2017 and is included in other liabilities on the condensed consolidated balance sheet. The derivative liability is classified within Level 2 of the fair value hierarchy in which fair value is measured using quoted prices in active markets for similar assets and liabilities.

Debt and Financial Instruments

On December 15, 2016, we entered into a Fifth Amended and Restated Financing and Security Agreement (the “Credit Agreement”). The Credit Agreement provides for a revolving credit facility up to a maximum principal amount of $100 million expiring on December 31, 2021 and for a term loan in the principal amount of $40 million maturing on April 30, 2020. The Credit Agreement is secured by substantially all of our assets.

The maximum interest rate on the Credit Agreement is the daily one-month LIBOR market index rate (for borrowings in Dollars and Sterling) or the daily one month EURIBOR (for borrowings in Euros) plus 2.50%. Based on our financial performance, the interest rate can be reduced to a minimum rate of the daily one-month LIBOR market index rate plus 1.25%, with the rate being determined based on our maximum leverage ratio for the preceding four quarters. Each unpaid advance on the revolving loan will bear interest until repaid. The term loan is payable in monthly installments of principal in the amount of $1.0 million plus applicable interest, beginning on January 1, 2017. We may prepay the term loan or the revolving loan, in whole or in part, at any time without premium or penalty, subject to certain conditions. Amounts repaid or prepaid on the term loan may not be reborrowed.

The Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict our and our subsidiaries’ (subject to certain exceptions) ability to, among other things, grant liens, make investments, incur indebtedness, merge or consolidate, dispose of assets or make acquisitions. We are also required to maintain compliance with a minimum fixed charge coverage ratio and a maximum leverage ratio. We were in compliance with all of the financial covenants under the Credit Agreement as of March 31, 2017. As of March 31, 2017, our total long-term debt outstanding under the term loan was $37.0 million. In addition, there were $23.5 million of borrowings outstanding and $71.3 million of available borrowings under the Credit Agreement. For the three months ended March 31, 2017, the weighted average interest rate on our borrowings was 2.5%.

Effective March 1, 2017, we entered into an interest rate swap agreement which effectively fixed our interest rate on the remaining $37 million outstanding on our term loan to a fixed LIBOR of 1.59% plus the applicable margin under the Credit Agreement. We have designated the interest rate swap, which expires on April 1, 2020, as a cash flow hedge and have applied hedge accounting.
