Interest expense in the three and six months ended June 30, 2011 includes $100.0 million of interest paid to holders of the Convertible Debentures as a result of the May 2011 Dividend. The Indenture governing the Convertible Debentures requires the payment of contingent interest to the holders of the Convertible Debentures if the Board declares a dividend to its stockholders that is designated by the Board as an extraordinary dividend. The contingent interest is calculated as the amount derived by multiplying the per share declared dividend with the if-converted number of shares applicable to the Convertible Debentures.
