Long-Term Debt

1.00 % Convertible Senior Notes Due 2018

On December 2, 2013, we issued $1.5 billion of 1.00% convertible senior notes due 2018, or the Notes. The Notes are unsecured, unsubordinated obligations of the Company, which pay interest in cash semi-annually at a rate of 1.00% per annum. The Notes will mature on December 1, 2018 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 49.60 shares of common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of $20.16 per share of common stock), subject to adjustment as described in the indenture governing the Notes.

Holders may convert their notes at their option at any time prior to August 1, 2018 only under the following circumstances: (1) during any fiscal quarter commencing after the fiscal quarter ended on April 27, 2014 (and only during such fiscal 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 fiscal 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 August 1, 2018 to the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their notes regardless of the foregoing conditions. Upon conversion, we will pay cash up to the aggregate principal amount of the notes to be converted and 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, in respect of the remainder, if any, of our conversion obligation in excess of the aggregate principal amount of the notes being converted.

As of July 27, 2014, none of the conditions allowing holders of the Notes to convert had been met. The determination of whether or not the Notes are convertible must be performed quarterly. If the Notes become convertible at the option of the holder, the difference between the principal amount and the carrying value of the Notes would be reflected as convertible debt in the mezzanine equity section on our Condensed Consolidated Balance Sheets.

In accordance with ASC 470-20 Debt with Conversion and Other Options, all cash-settled convertible debt should be 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. The difference between the net 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 $1,351.8 million 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 3.15%. The carrying value of the permanent equity component reported in additional paid-in-capital was valued at $125.7 million and recorded as a debt discount. This amount, together with the $22.5 million purchaser's discount to the par value of the Notes represents the total unamortized debt discount of $148.2 million we recorded at the time of issuance of the Notes. The aggregate debt discount is amortized as interest expense over the contractual term of the Notes using the effective interest method using an interest rate of 3.15%.

The following table presents the carrying amounts of the liability and equity components:
