Ranking of Convertible Debt - Each series of Convertible Debt is an unsecured obligation which is subordinated in right of payment to the amounts outstanding under the Company's Senior Indebtedness. The Convertible Debt is subordinated to the Senior Indebtedness; ranks senior to the Company's indebtedness that is expressly subordinated in right of payment to it; ranks equal in right of payment to any of the Company's unsubordinated indebtedness that does not provide that it is senior to the Convertible Debt; ranks junior in right of payment to any of the Company's secured and unsecured unsubordinated indebtedness to the extent of the value of the assets securing such indebtedness; and is structurally subordinated to all indebtedness and other liabilities of the Company's subsidiaries. Summary of Conversion Features - Each series of Convertible Debt is convertible, subject to certain conditions, into cash, shares of the Company's common stock or a combination thereof, at the Company's election, at specified conversion rates (see table below), adjusted for certain events including the declaration of cash dividends. Except during the three-month period immediately preceding the maturity date of the applicable series of Convertible Debt, each series of Convertible Debt is convertible only upon the occurrence of (i) such time as the closing price of the Company's common stock exceeds the applicable conversion price (see table below) by 130% for 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter, (ii) during the 5 business day period after any 10 consecutive trading day period, or the measurement period, in which the trading price per $1,000 principal amount of notes of a given series for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the applicable conversion rate on each such trading day, or (iii) upon the occurrence of certain corporate events specified in the indenture of such series of Convertible Debt. In addition, for each series, with the exception of the 2024 Senior Convertible Debt, if at the time of conversion the applicable price of the Company's common stock exceeds the applicable conversion price at such time, the applicable conversion rate will be increased by up to an additional maximum incremental shares rate, as determined pursuant to a formula specified in the indenture for the applicable series of Convertible Debt, and as adjusted for cash dividends paid since the issuance of such series of Convertible Debt. However, in no event will the applicable conversion rate exceed the applicable maximum conversion rate specified in the indenture for the applicable series of Convertible Debt (see table below). The following table sets forth the applicable conversion rates adjusted for dividends declared since issuance of such series of Convertible Debt and the applicable incremental share factors and maximum conversion rates as adjusted for dividends paid since the applicable issuance date:
| Dividend adjusted rates as of September 30, 2025
| Conversion Rate |  | Approximate Conversion Price |  | Incremental Share Factor |  | Maximum Conversion Rate
2017 Senior Convertible Debt(1) | 23.1616 |  |  | $ | 43.17 |  |  | 11.5817 |  |  | 33.0053 |
2024 Senior Convertible Debt(1) | 8.2094 |  |  | $ | 121.81 |  |  | — |  |  | 10.4669 |
(1) As of September 30, 2025, the 2024 Senior Convertible Debt was not convertible. As of September 30, 2025, the holders of the 2017 Senior Convertible Debt have the right to convert their notes between October 1, 2025 and December 31, 2025 because the Company's common stock price has exceeded the applicable conversion price for such series by 130% for the specified period of time during the quarter ended September 30, 2025. With the exception of the 2024 Senior Convertible Debt, which may be redeemed by the Company on or after June 5, 2027, the Company may not redeem any series of Convertible Debt prior to the relevant maturity date and no sinking fund is provided for any series of Convertible Debt. Under the terms of the applicable indenture, the Company may repurchase any series of Convertible Debt in the open market or through privately negotiated exchange offers. Upon the occurrence of a fundamental change, as defined in the applicable indenture of such series of Convertible Debt, holders of such series may require the Company to purchase all or a portion of their Convertible Debt for cash at a price equal to 100% of the principal amount plus any accrued and unpaid interest. Additionally, holders of the 2024 Senior Convertible Debt may require the Company to purchase all or a portion of their 2024 Senior Convertible Debt for cash at a price equal to 100% of the principal amount plus any accrued and unpaid interest if, prior to the close of business on the business day immediately preceding June 1, 2027, the last reported sale price of our common stock is less than the applicable conversion price of the 2024 Senior Convertible Debt.

(1) The Company used proceeds from the issuance of Commercial Paper and cash generated from operations to finance such settlement Commercial Paper In September 2023, the Company established a Commercial Paper program under which the Company may issue short-term unsecured promissory notes up to a maximum principal amount outstanding at any time of $2.75 billion with a maturity of up to 397 days from the date of issue. The Company's obligations with respect to the payment of the Commercial Paper are guaranteed by certain of its subsidiaries. The Commercial Paper will be sold at a discount from par or alternatively, will be sold at par and bear interest rates that will vary based on market conditions and the time of issuance. The Company's intention is to reduce the amounts that would otherwise be available to borrow under the Company's Revolving Credit Facility by the outstanding amount of Commercial Paper. As of September 30, 2025, the Company had $1.12 billion of Commercial Paper outstanding. The weighted-average interest rate of the Company's outstanding Commercial Paper was 4.47% as of September 30, 2025. Pursuant to the Credit Agreement, as amended and restated in March 2025, the maximum principal amount outstanding at any time under the Commercial Paper program is $2.25 billion.
