5.25% Senior Notes due 2024

On May 21, 2014, the Company issued $250 million of 5.25% Senior Notes due 2024 (the “2024 Notes”). The Company will pay interest on the 2024 Notes semi-annually on June 15 and December 15, commencing on December 15, 2014, at a rate of 5.25% per year. The 2024 Notes will mature on June 15, 2024, unless earlier redeemed or purchased by the Company at the holder’s option under specified circumstances following a Change of Control or Asset Sale (each as defined in the Indenture related to the 2024 Notes) or upon the Company’s election to exercise its optional redemption rights, as described below. The Company incurred transaction fees of approximately $4.5 million, including underwriters’ discounts and commissions, in connection with the offering of the 2024 Notes, which were recorded as a deferred asset and are being amortized over the term of the 2024 Notes. The Company used $245.0 million of the proceeds to repay borrowings under its revolving credit facility.

The Company's obligations under the 2024 Notes are fully and unconditionally guaranteed, jointly and severally, by each of the Company’s existing and future wholly-owned domestic subsidiaries that is a guarantor or other obligor under the Company’s revolving credit facility and by certain of the Company’s other wholly-owned domestic subsidiaries.

At any time on or after June 15, 2019, the Company may, on one or more occasions, redeem some or all of the 2024 Notes at a redemption price of 102.625% of the principal amount of the 2024 Notes subject to redemption, declining, in annual increments of 0.875%, to 100% of the principal amount on June 15, 2022, plus accrued and unpaid interest. In addition, at any time prior to June 15, 2019, the Company may, on one or more occasions, redeem some or all of the 2024 Notes at a redemption price equal to 100% of the principal amount of the 2024 Notes redeemed, plus a “make-whole” premium and any accrued and unpaid interest. The “make-whole” premium is the greater of (a) 1.0% of the principal amount of the 2024 Notes subject to redemption or (b) the excess, if any, over the principal amount of the 2024 Notes of the present value, on the redemption date, of the sum of (i) the June 15, 2019 optional redemption price plus (ii) all required interest payments on the 2024 Notes through June 15, 2019 (other than accrued and unpaid interest to the redemption date), calculated based on a specified Treasury rate, generally for the period most nearly equal to the period from the redemption date to June 15, 2019, plus 50 basis points.

In addition, at any time prior to June 15, 2017, the Company may, on one or more occasions, redeem up to 35% of the aggregate principal amount of the 2024 Notes, using the proceeds of specified types of Company equity offerings and subject to specified conditions, at a redemption price equal to 105.25% of the principal amount of the Notes redeemed, plus accrued and unpaid interest.

The 2024 Notes contain covenants that, among other things, limit or restrict the Company’s ability, and the ability of its subsidiaries, to incur debt, create liens, consolidate, merge or dispose of certain assets, make certain investments, engage in acquisitions, pay dividends on, repurchase or make distributions in respect of capital stock and enter into swap agreements.

Classification of 3.875% Convertible Notes as a Current Liability

The Company’s 3.875% Convertible Senior Subordinated Notes due 2017 (the “Convertible Notes”) are convertible under certain circumstances, including in any fiscal quarter following an immediately preceding fiscal quarter in which the last reported sales price per share of our common stock for at least 20 days during a period of 30 consecutive trading days ending on the last day of such fiscal quarter exceeds 130% of the $61.32 per share conversion price of the Convertible Notes (approximately $79.72). Since the fourth quarter of 2013, the Company’s closing stock price has exceeded the 130% threshold described above and, accordingly, the Convertible Notes have been classified as a current liability as of September 28, 2014 and December 31, 2013. The determination of whether or not the Convertible Notes are convertible under such circumstances is made each quarter until maturity or conversion. Consequently, the Convertible Notes may not be convertible in one or more future quarters if the common stock price-based contingent conversion threshold is not met in such quarters, in which case the Convertible Notes would again be classified as long-term debt unless another conversion event set forth in the Convertible Notes has occurred. The Company has elected a net settlement method to satisfy the conversion obligation, under which it may settle the principal amount of the Convertible Notes in cash and settle the excess of the conversion value of the Convertible Notes over the principal amount of the notes in shares; however, cash will be paid in lieu of fractional shares. While the Company believes it has sufficient liquidity to repay the principal amounts due through a combination of its existing cash on hand and borrowings under its credit facility, the Company’s use of these funds could adversely affect its results of operations and liquidity. The classification of the Convertible Notes as a current liability had no impact on the Company's financial covenants.

Fair Value of Long-Term Debt

The carrying amount of long-term debt reported in the consolidated balance sheet as of September 28, 2014 is $1,060.7 million. The Company uses quoted market prices to estimate the fair value of its publicly traded debt. To estimate the fair value of debt for which there are no quoted market prices, the Company uses a discounted cash flow technique that incorporates a market interest yield curve with adjustments for duration, optionality and risk profile. The Company’s implied credit rating is a factor in determining the market interest yield curve. The following table provides the fair value of the Company’s debt as of September 28, 2014, categorized by fair value hierarchy level (see Note 10, “Fair value measurement,” in the Company’s annual report on Form 10-K for the year ended December 31, 2013 for further information):
