Allowance for Doubtful Accounts

Allowance for Expected Credit Losses

We adopted Accounting Standards Codification Topic 326, Current Expected Credit Losses, on January 1, 2020 using the modified retrospective transition method. The allowance for credit losses on expected future uncollectible accounts receivable is estimated based on the aging of accounts receivable, reviews of client credit reports, industry trends and economic indicators, as well as reviews of recent payment history for specific customers. The estimate is based largely on a formula-driven calculation but is supplemented with economic indicators and knowledge of potential write-offs of specific client accounts.
