In December 2010, the Company entered into a new $750.0 Revolving Credit Facility (the “Revolving Credit Facility”). Borrowings under the Revolving Credit Facility bear interest at an annual rate equal to the London interbank offered rate (“LIBOR”) (as defined) plus 225 basis points or Prime (as defined) plus 125 basis points. As of December 31, 2011, the rate under the Revolving Credit Facility was 2.7%. At December 31, 2011 and 2010 there were no amounts outstanding under the Revolving Credit Facility. Unless terminated earlier, the Revolving Credit Facility will mature on December 9, 2015.

Letters of credit outstanding under the Revolving Credit Facility Agreement aggregated $5.6 at December 31, 2011.

The Revolving Credit Facility Agreement contains an interest coverage ratio financial covenant (as defined in the Credit Agreement) that must be maintained at a level greater than 2.25 to 1. The Revolving Credit Facility Agreement also contains a total leverage ratio covenant (as defined in the Credit Agreement) which limits net debt to a 4.25 to 1 multiple of EBITDA (as defined in the Revolving Credit Facility Agreement). The Revolving Credit Facility Agreement is collateralized by substantially all of the Company’s assets and contains customary affirmative covenants, negative covenants, restrictions on the payment of dividends, and conditions precedent for borrowings, all of which were met as of December 31, 2011.
