Accounting Policies [Abstract]
Accounting Standards	Accounting StandardsEffective January 1, 2022, the company adopted Accounting Standards Update (ASU) No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This guidance requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers, as if it had originated the contracts. Deferred revenue acquired in a business combination is no longer required to be measured at its fair value, which had historically resulted in a deferred revenue impairment at the date of acquisition. The company will adopt this guidance for acquisitions completed on or after January 1, 2022.
