Bank Borrowings	11. BANK DEBT Our credit agreement provides a five-year, $400.0 million revolving credit facility. At our option, subject to the terms and conditions specified in the credit agreement, we may elect to increase the commitments under the credit facility up to an aggregate amount of $500.0 million. The credit facility matures on May 27, 2016, at which time borrowings will be payable in full. Borrowings and repayments may be made in multiple currencies including U.S. Dollars, Canadian Dollars, UK Pound Sterling and Euro. At December 31, 2012, we had aggregate borrowings of $134.2 million, compared to $131.8 million at December 31, 2011. Based on our financial covenants at December 31, 2012, a maximum of approximately $245 million was available in additional borrowings under the credit facility. At our option, borrowings under the credit facility bear interest at a variable rate equal to an applicable base rate or LIBOR, in each case plus an applicable margin. For LIBOR loans, the applicable margin will vary depending upon our consolidated leverage ratio (the ratio of total funded debt to adjusted EBITDA, as defined in the credit agreement). At December 31, 2012, the applicable margins on LIBOR and base rate loans were 1.25% and 0.25%, respectively. Depending upon our performance and financial condition, our LIBOR loans will have applicable margins varying between 1.00% and 2.00% and our base rate loans will have applicable margins varying between zero and 1.00%. Our average borrowing rate (including the impact of our interest rate swap agreements; see Note 10 — Derivatives and Hedging Activity) was 2.7% and 3.0% for the year ended December 31, 2012 and 2011, respectively. Our credit agreement contains certain financial covenants, including covenants that require that we maintain a consolidated leverage ratio of not greater than 3.25:1 (except for the first quarter of each calendar year when the covenant requires us to maintain a consolidated leverage ratio of not greater than 3.5:1) and a consolidated interest coverage ratio (the ratio of the sum of adjusted EBITDA (as defined in the credit agreement) and rental expense to the sum of cash interest expense and rental expense) of not less than 2.0:1. At December 31, 2012, under the definitions in the credit agreement, our consolidated leverage ratio was 1.3 and our consolidated interest coverage ratio was 4.4. In addition, the credit agreement contains customary affirmative and negative covenants (subject to customary exceptions), including covenants that limit our ability to incur liens or other encumbrances, make investments, incur indebtedness, enter into mergers, consolidations and asset sales, change the nature of our business and engage in transactions with affiliates, as well as customary provisions with respect to events of default. We were in compliance with the terms of our credit agreement at December 31, 2012; however, there can be no assurances that we will remain in compliance in the future.
