Allowance for Credit Losses

During the nine months ended September 30, 2021, there have been no significant changes in the factors that influenced management’s current estimate of expected credit losses, nor changes to the Company’s accounting policies or Current Expected Credit Losses methodology. The beginning balances, current period activity, and ending balances of the allocation for credit losses on accounts receivable and contract assets were not material.
