Debt Disclosure [Abstract]
Debt	Debt 2025 Credit Agreement In April 2025, we entered into a credit agreement (the 2025 Credit Agreement) with Wells Fargo Bank, National Association (Wells Fargo) as administrative agent and a swingline lender, and various other lender parties, which provides for an unsecured revolving credit facility of up to $2.5 billion (which facility may, at our request, be increased by up to $750 million in the aggregate subject to obtaining commitments from existing or new lenders for such increase and other conditions). The facility will mature on April 25, 2030, subject to the lenders’ ability to extend the maturity date by one year if we request such an extension in accordance with the terms of the 2025 Credit Agreement, up to a maximum of two such extensions. At our option, amounts borrowed under the 2025 Credit Agreement bear interest at either an adjusted Term Secured Overnight Finance Rate (Term SOFR) or a fluctuating base rate, in each case, plus an applicable margin determined on a quarterly basis based on our consolidated ratio of total indebtedness to EBITDA (as calculated in accordance with the 2025 Credit Agreement). To date, we have elected to calculate interest on the outstanding balance at an adjusted Term SOFR plus an applicable margin. On April 25, 2025, we borrowed $200.0 million under the 2025 Credit Agreement, and used the funds to repay outstanding indebtedness under the 2022 Credit Agreement, as discussed below under the 2022 Credit Agreement. During the second quarter of 2025, we paid down the entire $200.0 million balance under the 2025 Credit Agreement, which brought our aggregate outstanding balance to zero as of September 30, 2025. The 2025 Credit Agreement contains customary events of default and customary affirmative and negative covenants. As of September 30, 2025, we were in compliance with these covenants. The interest expense reported in our consolidated statements of operations for the nine months ended September 30, 2025 and 2024 relates to our borrowings under the 2025 Credit Agreement and 2022 Credit Agreement. 2022 Credit Agreement In March 2022, we entered into a credit agreement (the 2022 Credit Agreement) with Wells Fargo, as administrative agent and a swingline lender, and various other lender parties, providing for: (1) an unsecured revolving credit facility of up to $1.2 billion; and (2) a second unsecured revolving credit facility of up to $800.0 million. As of December 31, 2024, our outstanding aggregate principal balance under the 2022 Credit Agreement was $300.0 million. During the first quarter of 2025, we paid down $100.0 million of our balance under the 2022 Credit Agreement, which brought our aggregate outstanding balance down to $200.0 million as of March 31, 2025. On April 25, 2025, we terminated the 2022 Credit Agreement and entered into the 2025 Credit Agreement. We repaid in full all our obligations under the 2022 Credit Agreement in connection with the termination of the 2022 Credit Agreement and our entry into the 2025 Credit Agreement. There were no penalties associated with the early termination of the 2022 Credit Agreement.

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.
