[1] We included our 6.25% Senior Unsecured Notes due 2014 (the "6.25% Notes") in the current portion of long-debt on our December 31, 2013 Consolidated Balance Sheet because the 6.25% Notes are scheduled to mature on November 15, 2014. We included our 4.75% Convertible Senior Notes due 2023 (the "4.75% Notes") in the current portion of long-term debt on our December 31, 2012 Consolidated Balance Sheet because holders of the 4.75% Notes had an option to require us to repurchase their Notes for cash, stock, or a combination, at our election, at par on March 15, 2013. The 4.75% Notes were retired in the first quarter of 2013.
