In 2013, we entered into separately negotiated agreements with certain holders of the 2015 Notes to exchange $186.0 million principal amount for 21,208,303 shares of common stock and cash. Also in 2013, we used a portion of the net proceeds from the sale of the 2018 Notes and the 2020 Notes to repurchase $117.3 million aggregate principal amount of the 2015 Notes held by the Baker Entities, a related party, in privately negotiated transactions, for an aggregate consideration, including accrued interest, of approximately $500.0 million. The repurchase reduced common shares issuable upon conversion of the 2015 Notes by 13,368,883 shares. In October 2015, the remaining 2015 Notes were due and all but a de minimis principal amount were converted into common stock.
