DEBT

Senior Notes

On November 15, 2017, the Company issued $750.0 million of unsecured senior notes due December 1, 2027. The 2027 Notes accrue interest at a rate of 4.500% per annum. Interest on the 2027 Notes is due semi-annually on June 1 and December 1 of each year, beginning on June 1, 2018. The net proceeds from this offering were approximately $741.0 million, after deducting the underwriting discount and estimated offering expenses payable by the Company. Net proceeds from this offering were used to repurchase shares of the Company's common stock through an Accelerated Share Repurchase ("ASR") transaction which the Company entered into with Citibank, N.A. (the "ASR Counterparty") on November 13, 2017. The 2027 Notes will mature on December 1, 2027, unless earlier redeemed in accordance with their terms prior to such date. The Company may redeem the 2027 Notes at its option at any time in whole or from time to time in part prior to September 1, 2027 at a redemption price equal to the greater of (i) 100% of the aggregate principal amount of the 2027 Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments under such 2027 Notes, plus in each case, accrued and unpaid interest to, but excluding, the redemption date. Among other terms, under certain circumstances, holders of the 2027 Notes may require the Company to repurchase their 2027 Notes upon the occurrence of a change of control prior to maturity for cash at a repurchase price equal to 101% of the principal amount of the 2027 Notes to be repurchased plus accrued and unpaid interest to, but excluding, the repurchase date.

Credit Facility

Effective January 7, 2015, the Company entered into a credit agreement (the "Credit Agreement") with a group of financial institutions (the “Lenders”). The credit facility provides for a five year revolving line of credit in the aggregate amount of $250.0 million, subject to continued covenant compliance. The Company may elect to increase the revolving credit facility by up to $250.0 million if existing or new lenders provide additional revolving commitments in accordance with the terms of the Credit Agreement. A portion of the revolving line of credit (i) in the aggregate amount of $25.0 million may be available for issuances of letters of credit and (ii) in the aggregate amount of $10.0 million may be available for swing line loans, as part of, not in addition to, the aggregate revolving commitments. The credit facility bears interest at LIBOR plus 1.10% and adjusts in the range of 1.00% to 1.30% above LIBOR based on the ratio of the Company’s total debt to its adjusted earnings before interest, taxes, depreciation, amortization and certain other items (“EBITDA”) as defined in the Credit Agreement. In addition, the Company is required to pay a quarterly facility fee ranging from 0.125% to 0.20% of the aggregate revolving commitments under the credit facility and based on the ratio of the Company’s total debt to the Company’s consolidated EBITDA. As of March 31, 2019, there were no amounts outstanding under the credit facility.

The Credit Agreement contains certain financial covenants that require the Company to maintain a consolidated leverage ratio of not more than 3.5:1.0 and a consolidated interest coverage ratio of not less than 3.0:1.0. In addition, the Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the ability of the Company to grant liens, merge, dissolve or consolidate, dispose of all or substantially all of its assets, pay dividends during the existence of a default under the Credit Agreement, change its business and incur subsidiary indebtedness, in each case subject to customary exceptions for a credit facility of this size and type. The Company was in compliance with these covenants as of March 31, 2019.

Convertible Notes Offering

As noted below under “Subsequent Event,” all of the outstanding Convertible Notes were converted prior to their maturity on April 15, 2019. The following discussion gives effect to the Convertible Notes outstanding as of March 31, 2019.

During 2014, the Company completed a private placement of approximately $1.44 billion principal amount of 0.500% Convertible Notes due 2019. The net proceeds from this offering were approximately $1.42 billion, after deducting the initial purchasers’ discounts and commissions and the estimated offering expenses payable by the Company. The Company used approximately $82.6 million of the net proceeds to pay the cost of the Bond Hedges described below (after such cost was partially offset by the proceeds to the Company from the Warrant Transactions described below). The Company used the remainder of the net proceeds from the offering and a portion of its existing cash and investments to purchase an aggregate of approximately $1.5 billion of its common stock, as authorized under its share repurchase program. The Company used approximately $101.0 million to purchase shares of common stock from certain purchasers of the Convertible Notes in privately negotiated transactions concurrently with the closing of the offering, and the remaining $1.4 billion to purchase additional shares of common stock through an ASR which the Company entered into with the ASR counterparty on April 25, 2014 (the “ASR agreement”).

The Convertible Notes are governed by the terms of an indenture, dated as of April 30, 2014 (the “Indenture”), between the Company and Wilmington Trust, National Association, as trustee (the “Trustee”). The Convertible Notes are the senior unsecured obligations of the Company and bear interest at a rate of 0.500% per annum, payable semi-annually in arrears on April 15 and October 15 of each year.

In accordance with the terms of the Indenture, the conversion rate for the Convertible Notes was adjusted to 13.9983 shares of the Company’s common stock per $1,000 principal amount of Convertible Notes, which corresponds to a conversion price of $71.44 per share of common stock, as a result of a cash dividend paid in March 2019. The conversion rate is subject to adjustment from time to time upon the occurrence of certain events, including, but not limited to, the issuance of certain stock dividends on common stock, the issuance of certain rights or warrants, subdivisions, combinations, distributions of capital stock, indebtedness, or assets, the payment of cash dividends and certain issuer tender or exchange offers.

As of October 15, 2018, the Company received conversion notices from noteholders with respect to $273.0 million in aggregate principal amount of Convertible Notes requesting conversion as a result of the sales price condition having been met during the second and third quarter of 2018. In accordance with the terms of the Convertible Notes, in the fourth quarter of 2018 the Company made cash payments of this aggregate principal amount and delivered 1.3 million newly issued shares of its common stock in respect of the remainder of the Company's conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted, in full satisfaction of such converted notes. The Company received shares of its common stock under the Bond Hedges (as defined below) that offset the issuance of shares of common stock upon conversion of the Convertible Notes. See the discussion under “Convertible Note Hedge and Warrant Transaction” in this Note 11 for detailed information on the Bond Hedges. In addition, on or after October 15, 2018 until the close of business on the second scheduled trading day immediately preceding the April 15, 2019 maturity date, holders of the Convertible Notes had the right to convert their notes at any time, regardless of whether the sales price condition was met. Any conversions with respect to conversion notices received by the Company on or after October 15, 2018 settled on the maturity date. As of March 31, 2019, the outstanding balance, net of discount, of $1.16 billion of the Convertible Notes was included in current liabilities and the difference between the face value and carrying value of $1.2 million was included in temporary equity in the accompanying condensed consolidated balance sheets.

In accounting for the settlement of the Convertible Notes, the Company allocated the fair value of the settlement consideration remitted to the noteholders between the liability and equity components. The portion of the settlement consideration allocated to the extinguishment of the liability component was based on the fair value of that component immediately before extinguishment. The Company allocated the remaining settlement consideration to the reacquisition of the equity component and recognized this amount as a reduction of Stockholders' equity.

The Company may not redeem the Convertible Notes prior to the maturity date and no “sinking fund” is provided for the Convertible Notes, which means that the Company is not required to periodically redeem or retire the Convertible Notes. Upon the occurrence of certain fundamental changes involving the Company, holders of the Convertible Notes may require the Company to repurchase for cash all or part of their Convertible Notes in principal amounts of $1,000 or an integral multiple thereof at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

In accounting for the issuance of the Convertible Notes, the Company separated the Convertible Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the estimated fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the face value of the Convertible Notes as a whole. The excess of the principal amount of the liability component over its carrying amount ("debt discount") is amortized to interest expense over the term of the Convertible Notes using the effective interest method with an effective interest rate of 3.0 percent per annum. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.

In accounting for the transaction costs related to the Convertible Note issuance, the Company allocated the total amount incurred to the liability and equity components based on their relative values. Issuance costs attributable to the $1.4 billion liability component are being amortized to expense over the term of the Convertible Notes, and issuance costs attributable to the equity component are included along with the equity component in stockholders' equity. Additionally, a deferred tax liability of $8.2 million related to a portion of the equity component transaction costs which are deductible for tax purposes is included in Other liabilities in the accompanying condensed consolidated balance sheets.

Convertible Note Hedge and Warrant Transactions

In connection with the pricing of the Convertible Notes, the Company entered into convertible note hedge transactions relating to approximately 16.0 million shares of common stock (the "Bond Hedges") and also entered into separate warrant transactions (the "Warrant Transactions") with each of the Option Counterparties relating to approximately 16.0 million shares of common stock. As a result of the spin-off of its GoTo Business, the number of shares of the Company's common stock covered by the Bond Hedges and Warrant Transactions was adjusted to approximately 20.0 million shares.

The Bond Hedges are generally expected to reduce the potential dilution upon conversion of the Convertible Notes and/or offset any payments in cash, shares of common stock or a combination of cash and shares of common stock, at the Company’s election, that the Company is required to make in excess of the principal amount of the Convertible Notes upon conversion of any Convertible Notes, as the case may be, in the event that the market price per share of common stock, as measured under the terms of the Bond Hedges, is greater than the strike price of the Bond Hedges, which initially corresponds to the conversion price of the Convertible Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the Convertible Notes. The Warrant Transactions will separately have a dilutive effect to the extent that the market value per share of common stock, as measured under the terms of the Warrant Transactions, exceeds the applicable strike price of the warrants issued pursuant to the Warrant Transactions (the “Warrants”). The strike price of the Warrants was adjusted to $94.62 per share and the number of shares of the Company's common stock covered by the Warrant Transactions was adjusted to approximately 20.1 million shares as a result of the cash dividend paid in March 2019. The Warrants will expire in ratable portions on a series of expiration dates commencing after the maturity of the Convertible Notes. The Bond Hedges and Warrants are not marked to market as the value of the Bond Hedges and Warrants were initially recorded in stockholders' equity and continue to be classified within stockholders' equity. As of March 31, 2019, no warrants have been exercised.

Aside from the initial payment of a premium to the Option Counterparties under the Bond Hedges, which amount is partially offset by the receipt of a premium under the Warrant Transactions, the Company is not required to make any cash payments to the Option Counterparties under the Bond Hedges and will not receive any proceeds if the Warrants are exercised.

Subsequent Event

All Convertible Notes were converted by their beneficial owners prior to their maturity on April 15, 2019. In accordance with the terms of the Indenture, on April 15, 2019 the Company paid $1.16 billion in the outstanding aggregate principal amount of the Convertible Notes and delivered 4.9 million newly issued shares of its common stock in respect of the remainder of the Company's conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted, in full satisfaction of such converted notes. The Company received shares of its common stock under the Bond Hedges that offset the issuance of shares of common stock upon conversion of the Convertible Notes.
