Convertible Subordinated Notes Due 2015

In January 2008, the Company completed an underwritten public offering of $172.5 million aggregate principal amount of unsecured 3% Convertible Subordinated Notes due January 15, 2015 (2015 Notes). The financing raised proceeds, net of issuance costs, of $166.7 million. On June 4, 2013, the Company called for the redemption of all outstanding 2015 Notes, $172.5 million principal amount, pursuant to the redemption right in the indenture governing the 2015 Notes. Any 2015 Notes outstanding on July 5, 2013 were to be redeemed in cash for 100% of the principal amount, plus accrued and unpaid interest to, but excluding, the redemption date. The 2015 Notes were convertible at any time prior to 5:00 p.m. Eastern time on July 3, 2013 into shares of the Company’s common stock at a conversion rate of 38.6548 shares per $1,000 principal amount (equivalent to a conversion price of approximately $25.87 per share). All of the convertible subordinated notes, $172.5 million principal amount, were converted into 6,667,932 of the Company’s common stock between June 30, 2013 and July 3, 2013 and none were redeemed for cash. As a result of the conversion, unamortized debt issuance costs of $1.3 million was reclassified from other long-term assets to additional paid-in capital in the third quarter of 2013.

Amortization of the debt issuance costs ceased upon the conversion of the 2015 Notes. Amortization expense was negligible in the three months ended September 30, 2013, $0.2 million in the three months ended September 30, 2012, $0.4 million in the nine months ended September 30, 2013 and $0.6 million in the nine months ended September 2012.

Convertible Subordinated Notes Due 2023

In January 2013, the Company completed an underwritten public offering of $287.5 million aggregate principal amount of unsecured convertible subordinated notes which will mature on January 15, 2023. The financing raised proceeds, net of issuance costs, of approximately $281.2 million, less $36.8 million to purchase two privately-negotiated capped call option transactions in connection with the issuance of the notes. The notes bear interest at the rate of 2.125% per year, that is payable semi-annually in arrears, in cash on January 15 and July 15 of each year, beginning on July 15, 2013. The issuance costs, which are included in other long-term assets, are being amortized over the life of the notes. Unamortized issuance costs totaled $5.9 million as of September 30, 2013. Amortization expense was $0.2 million for the three months and $0.4 million for the nine months ended September 30, 2013.

The notes are convertible, at the option of the holder, into shares of the Company’s common stock at an initial conversion rate of 35.9903 shares per $1,000 principal amount of the notes, subject to adjustment in certain circumstances, which represents an initial conversion price of approximately $27.79 per share. Holders of the notes will be able to require the Company to repurchase some or all of their notes upon the occurrence of a fundamental change at 100% of the principal amount of the notes being repurchased plus accrued and unpaid interest. The Company may not redeem the notes prior to their stated maturity date.

In connection with the offering of the notes, the Company entered into two privately-negotiated capped call option transactions with a single counterparty. The capped call option transaction is an integrated instrument consisting of a call option on its common stock purchased by the Company with a strike price equal to the conversion price of $27.79 per share for the underlying number of shares and a cap price of $38.00 per share. The cap component is economically equivalent to a call option sold by the Company for the underlying number of shares with a strike price of $38.00 per share. As an integrated instrument, the settlement of the capped call coincides with the due date of the convertible debt. At settlement, the Company will receive from its hedge counterparty a number of the Company’s common shares that will range from zero, if the stock price is below $27.79 per share, to a maximum of 2,779,659 shares, if the stock price is above $38.00 per share. However, if the market price of the Company’s common stock, as measured under the terms of the capped call transactions, exceeds $38.00 per share, there is no incremental anti-dilutive benefit from the capped call. The aggregate cost of the capped call options was $36.8 million.

The terms of the capped call option agreements include a provision under which the Company would have been required to make cash payments to the counterparty if the debt offering did not close. As a result of this provision, the capped calls were recorded as derivative assets between the trade dates and the date of the closing of the debt offering, at which time the cash settlement provision was no longer applicable. Upon the closing of the debt offering, the capped call transactions met the criteria for classification as an equity instrument, and the Company reclassified the carrying value of the capped call derivative assets to stockholders’ equity. The change in fair value between the trade dates and the date at which the capped call derivative assets were reclassified to stockholders’ equity was $1.4 million, which was recorded as other income (expense), net, in the Company’s condensed consolidated statement of operations in the first quarter of 2013.
