4. ACCOUNTS RECEIVABLE

Our trade accounts receivable are recorded at net realizable value, which includes an allowance for estimated credit losses as described in Note 1, Nature of Operations and Summary of Significant Accounting Policies. Under the guidance found in ASC Topic 326, the “expected credit loss” model replaced the previous “incurred loss” model and requires consideration of a broader range of information to estimate expected credit losses over the lives of our trade accounts receivable. Our prior methodology for estimating credit losses on our trade accounts receivable did not differ significantly from the new requirements of Topic 326, which was adopted in fiscal 2021.

We maintain an allowance for credit losses related to our trade accounts receivable for future expected credit losses resulting from the inability or unwillingness of our customers to make required payments. We estimate the allowance based upon historical bad debts, current customer receivable balances, age of customer receivable balances, and the customers’ financial condition in relation to a representative pool of assets consisting of customers with similar risk characteristics. The allowance is adjusted as appropriate to reflect differences in current conditions as well as changes in forecasted macroeconomic conditions. Receivables that do not share risk characteristics are evaluated on an individual basis, including those associated with customers that have a higher probability of default. Our estimate of credit losses includes expected current and future economic and market conditions related to the ongoing COVID-19 pandemic. We do not have a significant amount of notes or other receivables.

The following schedule provides a reconciliation of the activity in our allowance for estimated credit losses during the periods indicated (in thousands):
