The CECL model requires that estimated expected credit losses, including allowance for doubtful accounts, consider a broader range of information such as economic conditions and expected changes in market conditions. We adopted the new standard as of October 1, 2020. The adoption of this standard did not have a material impact on our Consolidated Financial Statements. In October 2021, the FASB issued a new standard that requires companies to apply ASC 606 to recognize and measure contract assets and contract liabilities in a business combination.
