Trade Accounts Receivable Trade Accounts Receivable
Trade accounts receivable includes both billed and unbilled amounts due from customers. Billed trade receivables generally do not bear interest. Unbilled receivables represent accrued revenue earned and recognized on contracts for which billings have not yet been presented to the customer. At October 31, 2021 and November 1, 2020, trade accounts receivable included unbilled receivables of $2.7 million and $3.2 million, respectively.
The Company maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable portfolio. In establishing the required allowance, management considers historical losses adjusted to take into account current market conditions, customers’ financial condition and current receivable aging and payment patterns. Additions to the allowance for doubtful accounts are recorded to Selling, administrative and other operating costs in the Consolidated Statement of Operations. The Company also maintains a sales allowance for specific customers related to billing disputes. The amount of the sales allowance is determined based on discount estimates and historical credits issued and additions to the sales allowance are recorded as a reduction to net revenue. Account balances are written off against the allowances when the Company believes it is probable the amount will not be received.

For the years ended October 31, 2021 and November 1, 2020, the activity in the allowance accounts were as follows (in thousands):
