Through March 31, 2013, the Company had purchased $114.1 million in principal amount of its Convertible Notes, none of which were repurchased subsequent to December 31, 2011, and the remaining outstanding balance is $0.9 million. As of December 31, 2011, all loan costs associated with the issuance have been expensed and there is no remaining net carrying amount of the equity component. The if-converted value of the Convertible Notes does not exceed their aggregate principal amount as of March 31, 2013 and there are no derivative transactions that were entered into in connection with the issuance of the Convertible Notes.
