[1] On March 15, 2013, holders of our 4.75% Convertible Senior Notes due 2023 (the “4.75% Notes”) may require us to repurchase their notes for cash at par, and accordingly, we included these notes in the current portion of long-term debt on our June 30, 2012 unaudited Consolidated Balance Sheet. The 4.75% Notes are redeemable in whole or in part at our option beginning March 15, 2013. Any 4.75% Notes not repurchased on March 15, 2013 or called for redemption by us will be reclassified to long-term debt. We included our 4.25% Convertible Senior Notes due 2023 (the “4.25% Notes”) in the current portion of long-term debt on our December 31, 2011 Consolidated Balance Sheet because holders of the 4.25% Notes had a repurchase option on March 15, 2012 for cash at par.
