2.25% Convertible Senior Notes Due 2019 [Abstract] |
2.25% Convertible Senior Notes Due 2019 | 9. 2.25% Convertible Senior Notes Due 2019 On June 30, 2014, the Company issued $330 million of 2.25% convertible senior notes due 2019 (the “Notes”). The Notes are unsecured, unsubordinated obligations of the Company, which pay interest in cash semi-annually, on January 1 and July 1, at a rate of 2.25% per annum. The Notes will mature on July 1, 2019 unless earlier repurchased or converted in accordance with their terms prior to such date. The Notes may be converted, under the conditions specified below, based on an initial conversion rate of 7.9353 shares of common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $126.02 per share of common stock), subject to adjustment as described in the indenture governing the Notes. The net proceeds from the Notes were approximately $322 million, net of the transaction costs. Holders may convert their notes at their option at any time prior to January 1, 2019 only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on September 30, 2014 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. On or after January 1, 2019 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. As of March 31, 2015, none of the conditions allowing holders of the Notes to convert had been met. In accordance with ASC 470-20 Debt with Conversion and Other Options , the convertible debt instrument within the scope of the cash conversion subsection, was separated into debt and equity components at issuance and be assigned a fair value. The value assigned to the debt component is the estimated fair value, as of the issuance date, of a similar debt without the conversion feature. As of June 30, 2014, the Company determined the fair value of the liability component of the Notes by reviewing market data that was available for senior, unsecured nonconvertible corporate bonds issued by comparable companies. Assumptions used in the estimate represent what market participants would use in pricing the liability component, including market interest rates, credit standing, and yield curves, all of which are defined as level 2 observable inputs. The difference between the cash proceeds and this estimated fair value, represents the value assigned to the equity component and is recorded as a debt discount. The debt discount is amortized using the effective interest method from the origination date through its stated contractual maturity date. The initial debt component of the Notes was valued at $283,015 thousands, based on the contractual cash flows discounted at an appropriate market rate for a non-convertible debt at the date of issuance, which was determined to be 5.55%. The carrying value of the permanent equity component reported in additional paid-in-capital was initially valued at $46,985 thousands. The effective interest rate after allocation of transaction costs to the liability component is 6.1% and is used to amortize the debt discount and transaction costs. Additionally, the Company recorded a deferred tax liability related to the additional paid in capital component of the convertible notes amounting to $16,445 thousands. The following table presents the carrying amounts of the liability and equity components:

Capped call transactions The net proceeds from the Notes were approximately $321,732 thousands, after considering the transaction costs in an amount of $8,268 thousands. In connection with the issuance of the Notes, the Company paid $19,668 thousands to enter into capped call transactions with respect to its common shares (the “Capped Call Transactions”), with certain financial institutions. The Capped Call Transactions are expected generally to reduce the potential dilution upon conversion of the Convertible Notes and / or offset any cash payments the Company may be required to make in excess of the principal amount of any converted notes in the event that the market price of the common shares is greater than the strike price of the Capped Call Transactions, initially set at $126.02 per common share, which corresponds to the initial conversion price of the Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the Notes, and have a cap price of approximately $155.78 per common share. Therefore, as a result of executing the Capped Call Transactions, the Company will reduce its exposure to potential dilution once the market price of its common shares exceeds the strike price of $126.02 and up to a ca p price of approximately $155.78 per common share. The Capped Call Transactions allow us to receive shares of our common stock and/or cash related to the excess conversion value that the Company would pay to the holders of the Notes upon conversion, up to the above mentioned cap price. The $19,668 thousands cost of the capped call transactions, which net of deferred income tax effect amounts to $12,784 thousands, is included as a net reduction to additional paid-in capital in the stockholders’ equity section of these interim condensed consolidated balance sheets, in accordance with the guidance in ASC 815-40 Derivatives and Hedging-Contracts in Entity’s Own Equity.
