Equity [Abstract]
Convertible Preferred Stock	Convertible Preferred StockThird quarter CPS dividends of $10 million were paid in August 2022. In October 2022, our Board of Directors approved the payment of fourth quarter CPS dividends of $10 million, payable in November 2022. Each share of CPS is convertible at the holder's option at any time into 44.9585 shares of our common stock per share of CPS. The conversion rate is subject to certain customary adjustments, but no payment or adjustment for accumulated but unpaid dividends will be made upon conversion, subject to certain limited exceptions. The CPS may not be redeemed by us; however, we may, at any time on or after May 20, 2022, elect to cause all outstanding shares of CPS to be converted into shares of our common stock at the conversion rate, subject to certain conditions (and, if such conversion occurs prior to May 20, 2024, the payment of a cash make-whole premium). The most significant condition to our ability to force a conversion prior to May 2024 is the requirement that our common stock trade above $28.92 for 20 consecutive trading days. We estimate that the cash make-whole payment would have been $84 million at September 30, 2022 (assuming we minimally exceeded the minimum trading price to invoke the conversion). If a make-whole fundamental change, as defined in the certificate of designations for the CPS, occurs, we will in certain circumstances be required to increase the conversion rate for a holder who elects to convert shares of CPS in connection with such make-whole fundamental change.
