Factoring of Accounts Receivable [Abstract]
Factoring of Accounts Receivable	Factoring of Accounts Receivable For certain accounts receivable, we use non-recourse factoring arrangements with third-party financial institutions to manage our working capital and cash flows. Under these arrangements, we sell receivables to a financial institution for cash at a discount to the face amount. As part of the factoring arrangements, we perform certain collection and administrative functions for the receivables sold. For the three and six months ended June 30, 2021, we sold receivables totaling $105.6 million and $211.9 million, net of discounts and fees of $0.3 million and $0.6 million, respectively. For the three and six months ended June 30, 2020, we sold receivables totaling $94.0 million and $264.5 million, net of discounts and fees of $0.6 million and $1.6 million, respectively.
