Credit Agreement

We are party to a Credit Agreement, which provides for an unsecured delayed draw term loan facility described below (the “Term Loan”), and an unsecured $500 million revolving credit facility (the “Credit Facility”). Borrowings under our Credit Agreement bear interest based, at our election, on a base rate or other defined rate, plus in each case the applicable margin. In addition to interest payable on the principal amount of indebtedness outstanding from time to time under the Credit Agreement, we are required to pay a quarterly commitment fee.

The Credit Agreement contains customary non-financial and financial covenants, including a net leverage ratio and an interest coverage ratio. As of March 31, 2019, we were in compliance with all financial and non-financial covenants under the Credit Agreement and other long-term debt. Effective as of the date of the Sixth Amendment to the Credit Agreement described below, there are no guarantors as parties to the Credit Agreement.

In January 2019, we entered into a Sixth Amendment to the Credit Agreement that provided for a delayed draw term loan facility in an aggregate principal amount of $600 million, under which we may request up to ten advances, each in a minimum principal amount of $50 million, until July 31, 2020. The Term Loan will amortize in quarterly installments, commencing on September 30, 2020, equal to the principal amount of the Term Loan outstanding multiplied by rates ranging from 1.25% to 2.50% (depending on the applicable fiscal quarter) for each fiscal quarter. The Term Loan expires on January 31, 2024; therefore, any remaining outstanding balance under the Term Loan will be due and payable on that date. As of March 31, 2019, $100 million was outstanding under the Term Loan. Each advance under the Term Loan results in a permanent reduction to its borrowing capacity; therefore, our borrowing capacity under the Term Loan as of March 31, 2019, was $500 million.

The Credit Facility expires on January 31, 2022; therefore, any amounts outstanding under the Credit Facility will be due and payable on that date. As of March 31, 2019, no amounts were outstanding under the Credit Facility, and outstanding letters of credit amounting to $2 million reduced our borrowing capacity under the Credit Facility to $498 million.

5.375% Notes due 2022

We had $700 million aggregate principal amount of senior notes (the “5.375% Notes”) outstanding as of March 31, 2019, which are due November 15, 2022, unless earlier redeemed. Interest on the 5.375% Notes at a rate of 5.375% per annum is payable semiannually in arrears on May 15 and November 15. The 5.375% Notes contain customary non-financial covenants and change in control provisions.

4.875% Notes due 2025

We had $330 million aggregate principal amount of senior notes (the “4.875% Notes”) outstanding as of March 31, 2019, which are due June 15, 2025, unless earlier redeemed. Interest on the 4.875% Notes at a rate of 4.875% per annum is payable semiannually in arrears on June 15 and December 15. The 4.875% Notes contain customary non-financial covenants and change of control provisions.

1.125% Cash Convertible Senior Notes due 2020

In the first quarter of 2019, we entered into a privately negotiated note purchase agreement with certain holders of our outstanding 1.125% cash convertible senior notes due January 15, 2020 (the “1.125% Convertible Notes”), pursuant to which we repaid $46 million aggregate principal amount, or $44 million aggregate carrying amount, of the 1.125% Convertible Notes. In addition, we paid $115 million to settle the 1.125% Convertible Notes’ embedded cash conversion option feature at fair value (which is a derivative liability we refer to as the “1.125% Conversion Option”).

In the three months ended March 31, 2019, we recorded a gain on debt extinguishment of $3 million for the 1.125% Convertible Notes purchase (net of accelerated original issuance discount amortization), primarily relating to a favorable mark to market valuation on the partial termination of the Call Spread Overlay executed in connection with the related debt extinguishment. This gain is reported in “Other (income) expenses, net” in the accompanying consolidated statements of income. No common shares were issued in connection with the transaction.

In connection with the 1.125% Convertible Notes purchases, we also entered into privately negotiated agreements in the first quarter of 2019, to partially terminate the Call Spread Overlay, defined and further discussed in Note 8, “Derivatives,” and Note 9, “Stockholders' Equity.” The net cash proceeds from the Call Spread Overlay partial termination transactions partially offset the cash paid to settle the 1.125% Convertible Notes.

Following the transaction described above, we had $206 million aggregate principal amount of the 1.125% Convertible Notes outstanding at March 31, 2019. Interest at a rate of 1.125% per annum is payable semiannually in arrears on January 15 and July 15. The 1.125% Convertible Notes are convertible only into cash, and not into shares of our common stock or any other securities. The initial conversion rate is 24.5277 shares of our common stock per $1,000 principal amount, or approximately $40.77 per share of our common stock. Upon conversion, in lieu of receiving shares of our common stock, a holder will receive an amount in cash, per $1,000 principal amount, equal to the settlement amount, determined in the manner set forth in the indenture. We may not redeem the 1.125% Convertible Notes prior to the maturity date. The 1.125% Convertible Notes are convertible by the holders within one year of the current balance sheet date until they mature; therefore, they are reported in current portion of long-term debt.

Concurrent with the issuance of the 1.125% Convertible Notes in 2013, the 1.125% Conversion Option was separated from the 1.125% Convertible Notes and accounted for separately as a derivative liability, with changes in fair value reported in our consolidated statements of income until the 1.125% Conversion Option fully settles or expires. This initial liability simultaneously reduced the carrying value of the 1.125% Convertible Notes’ principal amount (effectively an original issuance discount), which is amortized to the principal amount through the recognition of non-cash interest expense over the expected life of the debt. The effective interest rate of 6% approximates the interest rate we would have incurred had we issued nonconvertible debt with otherwise similar terms. As of March 31, 2019, the 1.125% Convertible Notes had a remaining amortization period of less than one year, and their ‘if-converted’ value exceeded their principal amount by approximately $456 million and $581 million as of March 31, 2019 and December 31, 2018, respectively.

Cross-Default Provisions

The indentures governing the 4.875% Notes, the 5.375% Notes and the 1.125% Convertible Notes contain cross-default provisions that are triggered upon default by us or any of our subsidiaries on any indebtedness in excess of the amount specified in the applicable indenture.

Subsequent Events

1.125% Convertible Notes. In April 2019, we entered into privately negotiated note purchase agreements with certain holders of our outstanding 1.125% Convertible Notes. Under these agreements, we repaid $128 million aggregate principal amount, or approximately $123 million aggregate carrying amount, of the 1.125% Convertible Notes. In addition, we paid $332 million to settle the 1.125% Convertible Notes’ embedded cash conversion option feature at fair value.

Credit Agreement. We drew down an additional $120 million under the Term Loan in April 2019, further reducing borrowing capacity by that amount permanently.
