Significant Accounting Policies (Policies)	Mar. 31, 2020
Accounting Policies [Abstract]
Accounts Receivable	Accounts Receivable The Company maintains allowances for estimated losses resulting from the inability of customers to meet their financial obligations to the Company. The Company recognizes an allowance for doubtful accounts, on all accounts receivable, which considers the length of time receivables are past due, customers’ billing exposure, ability to pay, and contract terms. The Company also considers general and market business conditions, country, and political risk. Balances are written off when determined to be uncollectible. At March 31, 2020, the Company recorded $712.2 million of accounts and notes receivable, net of allowances of $11.9 million. Changes in the allowance were not material for the three months ended March 31, 2020.
