Credit Loss [Abstract]

Credit Losses

CREDIT LOSSESWe are exposed to credit losses primarily through our sales of products and services to our customers. We maintain allowances for credit losses for potentially uncollectible receivables. We base our estimates on a detailed analysis of specific customer situations and a percentage of our accounts receivable by aging category. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current economic conditions. Refer to "Note 2. Accounting Policies" for more information on our adoption of ASU 2016-13 on January 1, 2020, using the modified retrospective transition method.

Additional allowances may be required if either the financial condition of our customers was to deteriorate, or a strengthening U.S. dollar impacts the ability of foreign customers to make payments to us on their U.S. dollar-denominated purchases. We monitor our ongoing credit exposure through active review of counterparty balances against contract terms and due dates. Our activities include timely account reconciliations, dispute resolution, and payment confirmations. We may employ collection agencies and legal counsel to pursue recovery of defaulted receivables.

Account balances are charged off against the allowance when we believe it is probable the receivable will not be recovered. We may require collateralized asset support or a prepayment to mitigate credit risk. We do not have any off-balance sheet credit exposure related to our customers.

Accounts Receivable

The allowance for credit losses associated with accounts receivable was $5.7 million and $6.8 million at December 31, 2021, and December 31, 2020, respectively. Accounts receivable reflected on the balance sheet is net of this reserve. Based on an aging analysis, at December 31, 2021, approximately 90% of our accounts receivable had not yet reached the invoice due date and approximately 10% was considered past due, of which approximately 1.8% was greater than 60 days past due. At December 31, 2020, approximately 88% of our accounts receivable had not yet reached the invoice due date and approximately 12% was considered past due, of which approximately 1.5% was greater than 60 days past due. Write-offs and recoveries related to credit losses during the years ended December 31, 2021, 2020, and 2019 were not material.

Contract assets and lease receivables

The allowance for credit losses associated with the contract assets and lease receivables was $4.4 million and $3.7 million at December 31, 2021 and 2020, respectively. The assets reflected on the balance sheet are net of these reserves. Historically, we have experienced low credit loss rates on our customer commitment programs and lease receivables. We apply judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience or, in the case of a new customer, published credit and financial information pertaining to the customer. Write-offs and recoveries related to credit losses during the years ended December 31, 2021, 2020, and 2019 were not material.
