DEBT
Revolving Credit Facility
In May 2023, the Company entered into a five-year unsecured revolving credit facility with a group of lenders. The revolving credit facility extends a revolving line of credit of up to $2 billion to the Company and provides for the issuance of up to $80 million of letters of credit, as well as up to $100 million of borrowings on same-day notice, referred to as swingline loans. Other than the swingline loans, which are available only in U.S. Dollars, the revolving loans and the letters of credit are available in U.S. Dollars, Euros, Pounds Sterling, and any other currency agreed to by the administrative agent and each of the lenders. The revolving credit facility contains a maximum leverage ratio covenant, compliance with which is a condition to the Company's ability to borrow. In May 2024, the Company extended the maturity date of the revolving credit facility from May 2028 to May 2029 pursuant to an extension request under the credit agreement.
Borrowings under the revolving credit facility will bear interest at a rate determined by reference to benchmark rates plus an applicable spread (ranging from 0% to 1.375%) based on the better of the Company's leverage or credit rating at the time of the borrowing. Undrawn balances available under the revolving credit facility are subject to commitment fees at the applicable rate determined by reference to the Company's leverage or credit rating. At December 31, 2025 and 2024, there were no borrowings outstanding and $19 million and $26 million, respectively, of letters of credit issued under the revolving credit facility.

Fair Value of Debt
At December 31, 2025 and 2024, the fair value of outstanding debt was approximately $18.9 billion and $18.8 billion, respectively, and was considered a "Level 2" fair value measurement (see Note 2). Fair value was estimated based upon actual trades at the end of the reporting period or the most recent trade available as well as the Company's stock price at the end of the reporting period, as applicable. The fair value of the Company's debt in excess of the outstanding principal amount at December 31, 2025 is primarily due to interest rate fluctuations. The fair value of the Company's debt in excess of the outstanding principal amount at December 31, 2024 primarily relates to the conversion premium, which is the conversion value in excess of the principal amount, on the convertible senior notes that matured in May 2025.
Convertible Senior Notes
In April 2020, the Company issued $863 million aggregate principal amount of convertible senior notes due in May 2025 with an interest rate of 0.75% (the "May 2025 Notes"). The May 2025 Notes were convertible, subject to certain conditions, into the Company's common stock at a contractually determined conversion price. The May 2025 Notes were convertible, at the option of the holder, prior to November 1, 2024, upon the occurrence of specific events, including but not limited to a change in control, or if the closing sales price of the Company's common stock for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter was more than 130% of the conversion price in effect for the notes on the last trading day of the immediately preceding quarter. In the event that all or substantially all of the Company's common stock was acquired on or prior to the maturity of the May 2025 Notes in a transaction in which the consideration paid to holders of the Company's common stock consists of all or substantially all cash, the Company would have been required to make additional payments in the form of shares of common stock to the holders of the May 2025 Notes in an aggregate value ranging from $0 to $235 million depending upon the date of the transaction and the then current stock price of the Company. Starting on November 1, 2024, note holders had the right to convert all or any portion of the May 2025 Notes, regardless of the Company's stock price. The May 2025 Notes were not redeemable by the Company prior to maturity. The holders could have required the Company to repurchase the May 2025 Notes for cash in certain circumstances. Interest on the May 2025 Notes was payable on May 1 and November 1 of each year. Prior to November 2024, if the note holders exercised their option to convert, the Company delivered cash to repay the principal amount of the May 2025 Notes and had the option to deliver shares of the Company's common stock or cash, to satisfy the conversion premium. As of November 1, 2024, note holders were entitled to repayment of the principal amount of the May 2025 Notes in cash, and if they exercised their option to convert, the note holders were entitled to cash payment for the conversion premium, settled at maturity. Based on the closing sales prices of the Company's common stock for the prescribed measurement periods, the May 2025 Notes were convertible at the option of the holder starting the second calendar quarter of 2023 until November 1, 2024, when they became convertible regardless of the Company's stock price. The May 2025 Notes were classified as "Short-term debt" in the Consolidated Balance Sheet as of December 31, 2024. At December 31, 2024, the estimated fair value of the May 2025 Notes was $2.1 billion and was considered a "Level 2" fair value measurement (see Note 2). For the year ended December 31, 2023, the weighted-average effective interest rate related to the May 2025 Notes was 1.2%.
Upon issuance and subsequent balance sheet-date reassessments through September 30, 2024, the conversion option of the May 2025 Notes qualified for the equity scope exception under ASC 815, Derivatives and Hedging, because the Company had the option to deliver either cash or shares of the Company's common stock to satisfy the conversion premium. Under such exception, the conversion option was not required to be accounted for as a separate instrument. On November 1, 2024, the Company irrevocably elected to settle the conversion premium in cash. Upon that election, the conversion option no longer qualified for the exception and was deemed to be an embedded derivative which required bifurcation from the debt contract. Upon bifurcation of the conversion option, the Company recorded an embedded derivative liability at fair value of $1.2 billion, a debt discount reducing the carrying value of the May 2025 Notes to zero, and a loss of $428 million. The debt discount was amortized over the remaining term of the May 2025 Notes using the straight-line method. The fair value of the embedded derivative liability (considered a "Level 2" fair value measurement; see Note 2), was $1.3 billion at December 31, 2024 and is included in "Accrued expenses and other current liabilities" in the Consolidated Balance Sheet. The unamortized debt discount and debt issuance costs was $523 million at December 31, 2024.
The Company recognized the following activity related to the conversion option of the May 2025 Notes in the Consolidated Statements of Operations:

In May 2025, upon the maturity of the May 2025 Notes, the Company paid $1.9 billion in cash in the aggregate to repay the principal amount and settle the conversion premium of $1.1 billion. In addition, the Company paid the applicable accrued and unpaid interest relating to May 2025 Notes. During the year ended December 31, 2024, the Company paid $198 million in aggregate upon the conversion of the May 2025 Notes at the holders' option, to repay the principal amount of $78 million due upon conversion and an additional $120 million conversion premium.
