Subsequent Events On May 3, 2013, we entered into a $500 million five-year, amended and restated revolving credit agreement, which we refer to as the 2013 Credit Agreement, with the financial institutions identified therein as lenders and Citibank, N.A. as Administrative Agent. The 2013 Credit Agreement is guaranteed by our material subsidiaries and is supported by a security interest in all of our and our subsidiaries’ assets. The 2013 Credit Agreement amends and restates in its entirety the 2011 Credit Agreement, dated as of December 16, 2011. The 2013 Credit Agreement provides for an initial $500 million in revolving credit facilities, and, under specified circumstances, the revolving credit facility can be increased or one or more incremental term loan facilities can be added, provided that the incremental credit facilities do not exceed in the aggregate the sum of (a) $75 million plus (b) an additional amount not less than $25 million, so long as our total secured leverage ratio, calculated giving pro forma effect to the requested incremental borrowing and other customary and appropriate pro forma adjustment events, including any permitted acquisitions, is no greater than 2.5:1.0.

The interest rates applicable to the revolving credit facility are, at our option, either (a) the LIBOR multiplied by the statutory reserve rate plus an interest margin ranging from 1.50% to 2.25% based on our consolidated leverage ratio, or (b) a base rate (which is equal to the greatest of (a) Citibank’s prime rate, (b) the federal funds effective rate plus 0.50% and (c) the one-month LIBOR plus 1.00% plus an interest margin ranging from 0.50% to 1.25% based on our consolidated leverage ratio.
