Long-Term Debt | Long-Term Debt The following table summarizes the carrying value of our outstanding debt (in millions, except percentages): March 31, 2021 December 31, 2020 2030 Notes 2022 Notes 2030 Notes 2022 Notes Long-term debt Principal $ 1,500 $ 135 $ 1,500 $ 169 Less: debt issuance cost and debt discount, net of amortization (17) (7) (18) (11) Net carrying amount $ 1,483 $ 128 $ 1,482 $ 158 Effective interest rate of the liability component - 2022 Notes 4.75% Effective interest rate - 2030 Notes 1.53% The effective interest rates for the 2030 Notes and 2022 Notes include interest payable, amortization of debt issuance cost and amortization of debt discount, as applicable. We consider the fair value of the 2030 Notes and 2022 Notes at March 31, 2021 to be a Level 2 measurement. The estimated fair value of the 2030 Notes and 2022 Notes at March 31, 2021 and December 31, 2020 is based on the closing trading price per $100 of the 2030 Notes and 2022 Notes were as follows (in millions): March 31, 2021 December 31, 2020 2022 Notes $ 479 $ 687 2030 Notes $ 1,354 $ 1,463 2030 Notes In August 2020, we issued 1.40% fixed rate ten 2022 Notes In May and June 2017, we issued an aggregate of $782.5 million of 0% convertible senior notes (the “2022 Notes”), which are due June 1, 2022 unless earlier converted or repurchased in accordance with their terms. The 2022 Notes do not bear interest, and we cannot redeem the 2022 Notes prior to maturity. The 2022 Notes are unsecured obligations and do not contain any financial covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by us or any of our subsidiaries. In accounting for the issuance of the 2022 Notes and the related transaction costs, we valued and bifurcated the conversion option from the host debt instrument, referred to as debt discount, and recorded the conversion option of $160 million in equity at issuance. The resulting debt discount and transactions costs allocated to the liability component are amortized to interest expense using the effective interest method over the term of the 2022 Notes. Upon conversion of the 2022 Notes, we may choose to pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock upon settlement. We currently intend to settle the principal amount of the 2022 Notes with cash. Convertible Date Initial Conversion Price per Share Initial Conversion Rate per $1,000 Par Value Initial Number of Shares (in millions) 2022 Notes February 1, 2022 $ 134.75 7.42 shares 6 Conversion of the 2022 Notes prior to the Convertible Date . At any time prior to the close of business on the business day immediately preceding February 1, 2022 (“Convertible Date”), holders of the 2022 Notes may convert their 2022 Notes at their option, only if one of the following conditions are met: • during any calendar quarter (and only during such calendar quarter) if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day (in each case, the “Conversion Condition”); or • during the five-business day period after any five-consecutive trading day period, or the measurement period, in which the trading price per $1,000 principal amount of the 2022 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; or • upon the occurrence of specified corporate events. For conversion requests received prior to maturity, the difference between the fair value and the amortized book value is recorded as a gain or loss on early note conversion. Conversion of the 2022 Notes on or after the Convertible Date. On or after the Convertible Date, a holder may convert all or any portion of its 2022 Notes at any time prior to the close of business on the second scheduled trading day immediately preceding maturity, regardless of the foregoing conditions, and such conversions will settle upon maturity. Upon settlement, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. The conversion price of the 2022 Notes will be subject to adjustment in some events. Holders of the 2022 Notes who convert their 2022 Notes in connection with certain corporate events that constitute a “make-whole fundamental change” are, under certain circumstances, entitled to an increase in the conversion rate. Additionally, in the event of a corporate event that constitutes a “fundamental change,” holders of the 2022 Notes may require us to purchase with cash all or a portion of the 2022 Notes upon the occurrence of a fundamental change, at a purchase price equal to 100% of the principal amount of the 2022 Notes plus any accrued and unpaid special interest, if any. The Conversion Condition for the 2022 Notes was met for all the quarters ended June 30, 2018 through March 31, 2021, except for the quarter ended December 31, 2018. Therefore, our 2022 Notes became convertible at the holders’ option beginning on July 1, 2018 and continue to be convertible through June 30, 2021, except for the quarter ended March 31, 2019 because the Conversion Condition for the 2022 Notes was not met for the quarter ended December 31, 2018. During the three months ended March 31, 2021, we paid cash to settle $34 million in principal of the 2022 Notes and the loss on the early note conversions was not material. As a result of the settlements, we also recorded a net reduction to additional paid-in capital, reflecting $102 million fair value adjustments to the settled conversion option partially offset by a $102 million benefit from the 2022 Note Hedge (as defined below). Based on conversion requests received through the filing date, we expect to settle in cash an aggregate of approximately $30 million in principal amount of the 2022 Notes during the second quarter of 2021. We may receive additional conversion requests that require settlement in the second quarter of 2021 and future periods. Repurchase of 2022 Notes On August 11, 2020, we repurchased $497 million in aggregate principal amount of the 2022 Notes (the “2022 Notes Repurchase”) funded in part by the $1.1 billion proceeds received from the partial unwind of the 2022 Note Hedge (as defined below). The 2022 Notes Repurchase was accounted for as a debt extinguishment in which $493 million and $1.1 billion were allocated to the liability and equity components of the 2022 Notes, respectively. The cash consideration allocated to the liability component was based on the estimated fair value of the liability component utilizing a discount rate assuming a similar liability per the Company’s credit rating with the same maturity, but without the conversion option, as of the repurchase date. The cash consideration allocated to the equity component was based on the aggregate cash consideration less the estimated fair value of the liability component. The loss on extinguishment of $39 million recorded as other income, net, represents the difference between the allocated cash consideration and the carrying value of the liability component, which includes the proportionate amounts of unamortized debt discount and unamortized debt issuance costs in the amount of $43 million. Note Hedge To minimize the impact of potential economic dilution upon conversion of the 2022 Notes, we entered into convertible note hedge transactions (the “2022 Note Hedge”) with certain investment banks, with respect to our common stock concurrently with the issuance of the 2022 Notes. Purchase Initial Shares Shares as of (in millions) 2022 Note Hedge $ 128 6 1 The 2022 Note Hedge covers shares of our common stock at a strike price per share that corresponds to the initial conversion price of the 2022 Notes, subject to adjustment, and are exercisable upon conversion of the 2022 Notes. If exercised, we may elect to receive cash, shares of our common stock, or a combination of cash and shares. The 2022 Note Hedge will expire upon the maturity of the 2022 Notes. The 2022 Note Hedge is intended to reduce the potential economic dilution upon conversion of the 2022 Notes in the event that the fair value per share of our common stock at the time of exercise is greater than the conversion price of the 2022 Notes. The 2022 Note Hedge is a separate transaction and is not part of the terms of the 2022 Notes. Holders of the 2022 Notes will not have any rights with respect to the 2022 Note Hedge. The 2022 Note Hedge does not impact earnings per share, as it was entered into to offset any dilution from the 2022 Notes. On August 11, 2020, in connection with the 2022 Notes Repurchase, we entered into partial unwind agreements (the “Note Hedge Unwind”) to reduce the number of options corresponding to the principal amount of the 2022 Notes Repurchase. We received $1.1 billion for the Note Hedge Unwind and the aggregate number of shares underlying the call options under the 2022 Note Hedge was reduced by 3.7 million shares. Consistent with early conversions of the 2022 Notes, proceeds received by the Company from the Note Hedge Unwind were used to settle a portion of the 2022 Notes Repurchase. Warrants Proceeds Initial Shares Strike Price First Expiration Date Shares as of (in millions) (in millions) (in millions) 2022 Warrants $ 54 6 $ 203.40 September 1, 2022 1 Separately, we entered into warrant transactions with certain investment banks, whereby we sold warrants to acquire, subject to adjustment, the number of shares of our common stock shown in the table above (the “2022 Warrants”). If the average market value per share of our common stock for the reporting period, as measured under the 2022 Warrants, exceeds the strike price of the respective 2022 Warrants, such 2022 Warrants would have a dilutive effect on our earnings per share to the extent we report net income. The 2022 Warrants are separate transactions and are not remeasured through earnings each reporting period. The 2022 Warrants are not part of the 2022 Notes or 2022 Note Hedge. In connection with the 2022 Notes Repurchase and early note conversions, we entered into partial unwind agreements to reduce the number of warrants outstanding under the 2022 Warrants by delivering an aggregate of 0.5 million and 2.3 million shares of our common stock during the three months ended March 31, 2021 and year ended December 31, 2020, respectively. According to the terms, the remaining portion of the 2022 Warrants will be net share settled and automatically exercised over a 60 trading day period beginning on the first expiration date as set forth above based on the daily volume-weighted average stock prices over the same 60 trading day period . We expect to issue additional shares of our common stock in the second half of 2022 upon the automatic exercise of the remaining portion of the 2022 Warrants. The remaining portion of the 2022 Warrants could have a dilutive effect to the extent that the daily volume-weighted average stock prices over a 60 trading day period beginning on September 1, 2022 exceeds the strike price of the 2022 Warrants. Based on the volume-weighted average stock price on March 31, 2021, the total number of shares of our common stock to be issued upon the automatic exercise of the remaining portion of the 2022 Warrants would be approximately 0.6 million. The actual number of shares of our common stock issuable upon the automatic exercise of the remaining portion of the 2022 Warrants, if any, is unknown at this time. |
