[1] In June 2013, we exercised our option to redeem all of the 10.00% Senior Unsecured Notes due 2017 (the "10.00% Notes") on July 15, 2013, as such, we included our 10.00% Notes in the current portion of long-term debt on our June 30, 2013 unaudited Consolidated Balance Sheet. 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.
