Debt Disclosure [Abstract]
Debt	DebtIn February of 2022, we redeemed $600 million aggregate principal amount of our $1.0 billion 3.8% senior notes that mature in November 2025. The early redemption of the notes resulted in a loss of $42 million, consisting of premiums and unamortized expenses. The loss is included in "Loss on early extinguishment of debt" in our condensed consolidated statements of operations for the three months ended March 31, 2022. We used cash on hand to fund the aggregate redemption price of the notes, which included the principal amount, the make-whole premium, and accrued interest, in the amount of $641 million. The remaining $400 million aggregate principal amount of the notes remains outstanding.
