Loans, Notes, Trade and Other Receivables Disclosure [Text Block]	5. TRADE RECEIVABLES We maintain an allowance for credit losses resulting from the inability of our customers to make required payments. We calculate the allowance based on 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. 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. Trade receivables are presented net of the related allowance for credit losses of approximately $0.9 million, $1.0 million and $1.3 million at March 31, 2025, December 31, 2024 and March 31, 2024, respectively.
