_______________________
(1) | The principal amount of these notes is $450 million.
(2) | The principal amount of these notes is $400 million.
Senior Notes due 2015 On June 16, 2014, in accordance with the optional redemption provisions of the notes, we redeemed all of the remaining outstanding principal amount of our Senior Notes due 2015 at a price established in accordance with the indenture governing the senior notes. We paid $57.2 million to holders of the notes at redemption and recorded a loss of $2.8 million. Senior Notes due 2019 In May 2014, in anticipation of the Clayton acquisition, we issued $300 million principal amount of Senior Notes due 2019 and received net proceeds of approximately $294.4 million. The notes bear interest at a rate of 5.500% per annum, payable semi-annually on June 1 and December 1 of each year, commencing on December 1, 2014. These notes mature on June 1, 2019 and include covenants customary for securities of their nature. Additionally, the indentures governing these notes include covenants restricting us from encumbering the capital stock of a designated subsidiary (as defined in the indenture) or disposing of any capital stock of any designated subsidiary unless either all of the stock is disposed of or we retain more than 80% of the stock. We have the option to redeem the notes, in whole or in part, at any time or from time to time prior to maturity at a redemption price equal to the greater of: (i) 100% of the aggregate principal amount of the notes to be redeemed and (ii) the make-whole amount, which is the present value of the notes discounted at the applicable treasury rate plus 50 basis points, plus, in each case, accrued interest thereon to the redemption date. Convertible Senior Notes due 2017 and 2019 During the three-month period ended June 30, 2014, our closing stock price exceeded the threshold required for the holders of our Convertible Senior Notes due 2019 to be able to exercise their conversion rights during the three-month period ending September 30, 2014, but it did not exceed the applicable threshold under the Convertible Senior Notes due 2017. In any period when holders of the Convertible Senior Notes due 2017 are eligible to exercise their conversion option, the equity component related to these instruments will be reclassified from permanent equity to mezzanine (temporary) equity, specifically in those instances when the issuer is required to settle the aggregate principal amount of the notes in cash. Therefore, if in any future period the holders of our Convertible Senior Notes due 2017 are able to exercise their conversion rights, then the difference between (1) the amount of cash deliverable upon conversion (i.e., par value of debt) and (2) the carrying value of the debt component will be reclassified from permanent equity to mezzanine equity, and will continue to be reported as mezzanine equity for any period in which the debt remains currently convertible. Issuance and transaction costs incurred at the time of the issuance of the convertible notes are allocated to the liability and equity components in proportion to the allocation of proceeds and accounted for as debt issuance costs and equity issuance costs, respectively. The convertible notes are reflected on our condensed consolidated balance sheets as follows:
