Long-Term Debt

Private Offering

On October 15, 2014, the Company completed a private offering of $1.05 billion aggregate principal of 7.25% Senior Notes due October 15, 2022 (the “Senior Notes”). The Senior Notes yielded an effective interest rate of 7.61% at issuance. The Senior Notes are governed by the terms of the indenture, dated as of October 15, 2014, by and among the Company and U.S. Bank National Association, as Trustee. Interest on the Senior Notes is payable in cash on April 15 and October 15 of each year.

The indenture covering the Senior Notes contains certain covenants limiting among other things, the ability of the Company and its restricted subsidiaries, with certain exceptions as described in the Indenture, to: (i) incur indebtedness or issue certain preferred stock; (ii) incur liens; (iii) pay dividends or make distributions in respect of capital stock; (iv) purchase or redeem capital stock; (v) make investments or certain other restricted payments; (vi) sell assets; (vii) issue or sell stock of restricted subsidiaries; (viii) enter into transactions with stockholders or affiliates; or (ix) effect a consolidation or merger.

The Senior Notes are guaranteed, jointly and severally, on a senior and unsecured basis by its direct and indirect wholly-owned existing and future domestic restricted subsidiaries, subject to certain exceptions. The Senior Notes rank equal in right of payment to all of our existing and future unsecured, unsubordinated obligations. The Senior Notes are effectively subordinated to the secured obligations of the Company and subsidiaries to the extent of the value of the assets securing such obligations.

Credit Facilities

On October 27, 2014, the Company entered into a credit agreement, which provides for a term loan of $2.2 billion and a revolving credit facility of $250 million. Borrowings under the Term Loan bear interest at a variable rate plus an applicable margin, subject to an all-in floor of 4.75%. As of December 31 2015, the Term Loan interest rate was 4.75%. Interest payments are payable quarterly. The Company has entered into interest rate swaps to manage interest rate risk on its long-term debt. See Note 14 Derivative Instruments.

The credit agreement requires the Company to prepay the Term Loan and Revolving Credit Facility, under certain circumstances or transactions defined in the credit agreement. Also, the Company may make optional prepayments of the Term Loans, in whole or in part, without premium or penalty. The Company made optional principal prepayments of $165 million in 2015. In February 2016, the Company made additional optional principal prepayments of $80 million. Unless satisfied by further optional prepayments, the Company is required to make a scheduled principal payment of $1.99 billion due on October 27, 2021.

The Revolving Credit Facility is available for working capital and other general corporate purposes including letters of credit. The amount (including letters of credit) cannot exceed $250 million. As of December 31, 2015, the Company established letters of credit totaling $3 million, which reduced funds available for other borrowings under the agreement to $247 million. The Revolving Credit Facility will mature and the related commitments will terminate on October 27, 2019.

Borrowings under the Revolving Credit Facility bear interest at a variable rate plus an applicable margin. As of December 31, 2015, the Revolving Credit Facility interest rate was 3.25%. Interest payments are payable quarterly. As of December 31, 2015 and December 31, 2014, the Company did not have any borrowings against the Revolving Credit Facility.

In addition to paying interest on outstanding principal amounts under the Revolving Credit Facility, the Company is required to pay a quarterly commitment fee to the lenders with respect to the unutilized commitments. The commitment fee rate is currently 0.375%. The commitment fee rate will be adjusted to 0.250%, 0.375% or 0.500% depending on the Company’s consolidated total secured net leverage ratio.

The Revolving Credit Facility contains certain covenants limiting among other things, the ability of the Company and its restricted subsidiaries, with certain exceptions as described in the agreement, to: (i) incur indebtedness, make guarantees or issue certain equity securities; (ii) pay dividends on its capital stock or redeem, repurchase or retire its capital stock; (iii) make certain investments, loans and acquisitions; (iv) sell certain assets or issue capital stock of restricted subsidiaries; (v) create liens or engage in sale-leaseback transactions; (vi) merge, consolidate or transfer or dispose of substantially all of their assets; (vii) engage in certain transactions with affiliates; (viii) alter the business it conducts; (ix) amend, prepay, redeem or purchase subordinated debt; and (x) enter into agreements limiting subsidiary dividends and distributions. The Revolving Credit Facility also requires the Company to comply with a financial covenant consisting of a quarterly maximum consolidated total secured net leverage ratio test that will be tested only at the end of the fiscal quarter if 20% of the commitments under the Revolving Credit Facility have been drawn and remain outstanding.

The Term Loan and obligations under the Revolving Credit Facility are collateralized by a security interest in substantially all of the Company’s assets as defined in the security agreement and guaranteed by its direct and indirect wholly-owned existing and future domestic restricted subsidiaries, subject to certain exceptions.

Debt issue costs of $26 million were recorded as of December 31, 2015; $19 million relates to the Senior Notes, $2 million relates to the Term Loan, and $5 million relates to the Revolver. These costs are amortized over 8, 7 and 7 years, respectively.

The Company entered into a bridge financing facility prior to the Acquisition, to ensure financing would be in place to consummate the transaction. Upon the closing of the Acquisition, at which time the Company had secured other long-term financing, the Company incurred $19 million of costs related to the bridge financing facility, which are included in interest expense for the year ended December 31, 2014.

The estimated fair value of our long-term debt approximated $3.1 billion at December 31, 2015 and $3.3 billion at December 31, 2014. These fair value amounts represent the estimated value at which the Company’s lenders could trade its debt within the financial markets and does not represent the settlement value of these long-term debt liabilities to the Company. The fair value of the long-term debt will continue to vary each period based on fluctuations in market interest rates, as well as changes to the Company’s credit ratings. This methodology resulted in a Level 2 classification in the fair value hierarchy.
