TRADE RECEIVABLES Trade receivables are presented net of the related allowance for uncollectible accounts of approximately $2.1 million, $3.5 million and $2.5 million at September 30, 2023, December 31, 2022 and September 30, 2022, respectively. We record the allowance based on a data-driven approach, including historical experience, the age of the receivables, receivable insurance status, and identification of customer accounts that are likely to prove difficult to collect due to various criteria including pending bankruptcy. However, estimates of the allowance in any future period are inherently uncertain and actual allowances may differ from these estimates. If actual or expected future allowances were significantly greater or less than established reserves, a reduction or increase to bad debt expense would be recorded in the period this determination was made. Our credit policy generally provides that trade receivables will be deemed uncollectible and written-off once we have pursued all reasonable efforts to collect on the account. In accordance with ASC 606, the return reserve liability netted against trade receivables was approximately $1.8 million, $2.1 million and $2.2 million at September 30, 2023, December 31, 2022 and September 30, 2022, respectively.
