Line Of Credit [Abstract]
Line Of Credit	11. Line of Credit On October 20, 2010, the Company entered into a senior secured credit agreement (the “amended credit agreement”) with PNC Bank. The maximum amount available under the amended credit agreement is $60,000, comprised of a $35,000 revolving facility, including a sublimit of up to $5,000 for letters of credit and a sublimit of up to $2,500 for swing loans (the “Revolving Facility”), and a $25,000 term facility (the “Term Facility”). The Company may request to increase the maximum amount available under the Revolving Facility to $50,000. The amended credit agreement will terminate, and all borrowings will become due and payable, on October 19, 2013. The Company and each of its U.S. subsidiaries are guarantors of the obligations under the amended credit agreement. Borrowings under the amended credit agreement are secured by substantially all of the Company’s assets (including a pledge of the capital stock of our subsidiaries (but limited to only 65% of the voting stock of first-tier foreign subsidiaries)). For the year ended December 31, 2010, the Company recorded $611 in deferred financing costs in connection with its credit agreements. As of June 30, 2012, the Company had outstanding borrowings of $27,500 with an average interest rate of 3.0% in connection with its acquisitions and working capital requirements. Borrowings under the amended credit agreement are cross-collateralized by a first priority perfected lien on the Company’s assets including, but not limited to, receivables, inventory, equipment, furniture, general intangibles, fixtures, real property and improvements. The amended credit agreement contains various terms and covenants that provide for restrictions on payment of dividends, dispositions of assets, investments and acquisitions and require the Company, among other things, to maintain minimum levels of tangible net worth, net income and fixed charge coverage. The Company was compliant with its financial covenants at June 30, 2012. In March 2011 and October 2010 in connection with borrowings of $25,000 and $10,000 under the Term and Revolver Facilities, the Company entered into three interest rate swap agreements. As of June 30, 2012, the notional amount of these agreements totaled $27,500 with a quarterly weighted fixed interest rate of 1.07%. These swaps are set to expire in October 2013. The Company entered into these swaps to manage fluctuations in cash flows resulting from interest rate risk. The Company has not designated any of its interest rate swaps as a hedge. The Company records each interest rate swap on its balance sheet at fair market value with the changes in fair value recorded as net gains or loss on change in fair market value of investments, net in its Consolidated Statement of Operations. During the six months ended June 30, 2012 the Company recorded a gain of $41 for the change in the fair value of its interest rate swap. See Footnote 2 - Summary of Significant Accounting Policies - Fair Value of Financial Instruments for information on the fair value of the Company’s interest rate swap.
