Long-Term Debt

1.00 % Convertible Senior Notes Due 2018

On December 2, 2013, we issued $1.50 billion in 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 repurchased or converted earlier in accordance with their terms prior to such date. Under the terms of the Notes, they may be converted based on an initial conversion rate of 49.5958 shares of common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of $20.1630 per share of common stock), subject to adjustment as described in the indenture governing the Notes.

As of October 25, 2015, 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 carrying value of the Notes would be classified as a current liability and 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.

The initial debt component of the Notes was valued at $1.35 billion 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 $126 million and recorded as a debt discount. This amount, together with the $23 million purchaser's discount to the par value of the Notes represents the total unamortized debt discount of $149 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 and an interest rate of 3.15%.

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