Borrowings	Borrowings On October 24, 2014, the Company entered into a credit agreement (as amended, the “Credit Agreement”) with certain lenders and JPMorgan Chase Bank, N.A., as Administrative Agent. The Credit Agreement provided for a $50,000 revolving credit facility (the “Credit Facility”), including a letter of credit sub-facility, for a period of five years. The Company had an option to increase the commitments under the Credit Facility by up to an additional $50,000, which it exercised on February 23, 2015 through an amendment to the Credit Agreement. The Credit Facility has a maturity date of October 24, 2019 and is voluntarily pre-payable from time to time without premium or penalty. The Company entered into a second amendment to the Credit Agreement effective as of September 28, 2015 to address a minor clarification to the definition of change of control. Borrowings under the Credit Agreement bear interest at a rate equal to the specified prime rate (alternate base rate) or adjusted LIBO rate, plus, an applicable margin. The applicable margin is tied to the Company’s leverage ratio and ranges from 0.25% to 0.75% per annum with respect to loans pegged to the specified prime rate, and 1.25% to 1.75% per annum on loans pegged to the adjusted LIBO rate. The revolving credit commitments under the Credit Agreement are subject to a commitment fee. The commitment fee is also tied to the Company’s leverage ratio, and ranges from 0.20% to 0.30% per annum on the average daily amount by which the aggregate revolving commitments exceed the sum of outstanding revolving loans and letter of credit obligations. The Credit Facility carried an effective interest rate of 2.21% per annum during the year ended December 31, 2016. Borrowings under the Credit Facility may be used for working capital, general corporate purposes and for acquisitions. The amount outstanding as of December 31, 2016 is $45,000, of which $10,000 is expected to be repaid within next twelve months and is included under “short-term borrowings” in the consolidated balance sheet. In connection with the financing, the Company incurred debt issuance costs, which are deferred and amortized as an adjustment to interest expense over the term of the Credit Facility. The unamortized debt issuance costs as of December 31, 2016 and December 31, 2015 was $272 and $368, respectively and is included under "other current assets" and “other assets” in the consolidated balance sheets. The Credit Facility is guaranteed by the Company's domestic subsidiaries and material foreign subsidiaries and is secured by all or substantially all of the assets of the Company and its material domestic subsidiaries. The Credit Agreement contains certain covenants including a restriction on our indebtedness, and a covenant to not permit the interest coverage ratio (the ratio of EBIT to cash interest expense) or the leverage ratio (total funded indebtedness to EBITDA), for the four consecutive quarter period ending on the last day of each fiscal quarter, to be less than 3.5 to 1.0 or 2.5 to 1.0, respectively. At December 31, 2016, we were in compliance with the financial covenants listed above.
