[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 as such, we included these notes in the current portion of long-term debt on our March 31, 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 and not called for redemption by us will be reclassified to long-term debt. On March 15, 2012, holders of our 4.25% Convertible Senior Notes due 2023 (the “4.25% Notes”) could have required us to repurchase their notes for cash at par and therefore, we included these notes in the current portion of long-term debt on our December 31, 2011 Consolidated Balance Sheet.
