BORROWINGS	9. BORROWINGS United States On May 2, 2011, the Company, its domestic subsidiaries, and certain of its Canadian subsidiaries entered into a new $125,000,000 Revolving Credit Facility Credit Agreement (Credit Agreement) with PNC Bank, N.A., Bank of America, N.A., Wells Fargo Bank, N.A. and Citizens Bank of Pennsylvania. This Credit Agreement replaced a prior revolving credit facility with a maximum credit line of $90,000,000 and a $20,000,000 term loan. The Credit Agreement provides for a five-year, unsecured revolving credit facility that permits borrowing up to $125,000,000 for the U.S. borrowers and a sublimit of the equivalent of $15,000,000 U.S. dollars that is available to the Canadian borrowers. Providing no event of default exists, the Credit Agreement contains a provision that provides for an increase in the revolver facility of $50,000,000 that can be allocated to existing or new lenders if the Company's borrowing requirements should increase. The Credit Agreement includes a sublimit of $20,000,000 for the issuance of trade and standby letters of credit. Borrowings under the Credit Agreement will bear interest at rates based upon either the base rate or LIBOR-based rate plus applicable margins. Applicable margins are dictated by the ratio of the Company's indebtedness less cash on hand to the Company's consolidated EBITDA, as defined in the underlying Credit Agreement. The base rate is the highest of (a) PNC Bank's prime rate, (b) the Federal Funds Rate plus .50% or (c) the daily LIBOR rate, as defined in the underlying Credit Agreement, plus 1.00%. The base rate spread ranges from 0.00% to 1.00%. LIBOR-based rates are determined by dividing the published LIBOR rate by a number equal to 1.00 minus the percentage prescribed by the Federal Reserve for determining the maximum reserve requirements with respect to any Eurocurrency funding by banks on such day. The LIBOR-based rate spread ranges from 1.00% to 2.00%. The Credit Agreement includes two financial covenants: (a) the Leverage Ratio, defined as the Company's Indebtedness less cash on hand divided by the Company's consolidated EBITDA, which must not exceed 3.00 to 1.00 and (b) Minimum Interest Coverage, defined as consolidated EBITDA less Capital Expenditures divided by consolidated interest expense, which must be no less than 3.00 to 1.00. The Credit Agreement permits the Company to pay dividends and distributions and make redemptions with respect to its stock providing no event of default or potential default (as defined in the facility agreement) has occurred prior to or after giving effect to the dividend, distribution, or redemption. Dividends, distributions, and redemptions are capped at $15,000,000 per year when funds are drawn on the facility. If no drawings on the facility exist, dividends, distributions, and redemptions in excess of $15,000,000 per year are subjected to a limitation of $75,000,000 in aggregate. The $75,000,000 aggregate limitation also includes certain loans, investments, and acquisitions. The Company is permitted to acquire the stock or assets of other entities with limited restrictions providing that the Leverage Ratio does not exceed 2.50 to 1.00 after giving effect to the acquisition. Other restrictions exist at all times including, but not limited to, limitation of the Company's sale of assets, other indebtedness incurred by either the borrowers or the non-borrower subsidiaries of the Company, guaranties, and liens. As of June 30, 2012, the Company was in compliance with the Credit Agreement's covenants. The Company had no outstanding borrowings under the revolving credit facility at June 30, 2012 or December 31, 2011 and had available borrowing capacity of $123,839,000 at June 30, 2012. United Kingdom A subsidiary of the Company has a working capital facility with NatWest Bank for its United Kingdom operations which includes an overdraft availability of £1,500,000 pounds sterling (approximately $2,356,000 at June 30, 2012). This credit facility supports the working capital requirements and is collateralized by substantially all of the assets of its United Kingdom operations. The interest rate on this facility is the financial institution's base rate plus 1.50%. Outstanding performance bonds reduce availability under this credit facility. There were no borrowings or performance bonds outstanding on this facility as of June 30, 2012 or December 31, 2011. The expiration date of this credit facility is September 30, 2012.
