[1] 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 a repurchase option 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.
