Estimates also affect the reported amounts of revenue and expense during the reporting period. Significant items subject to estimates and assumptions include the valuation allowance for inventories, allowance for doubtful accounts, realizability of deferred tax assets and long-lived asset impairment testing. Actual results could differ from those estimates.

CY2022	us-gaap	Prior Period Reclassification Adjustment Description PriorPeriodReclassificationAdjustmentDescription	<b><i>Revision and Immaterial Correction of an Error in Previously Issued Financial Statements</i></b>The Company identified an error related to the classification of the activity on our line of credit facility with Bank of America at December 31, 2021 as reported on Form 10-K. In our December 31, 2021 consolidated financial statements, we incorrectly classified borrowings and payments on our line of credit facility on a net basis within the financing section of the consolidated cash flow statement; this activity should be shown on a gross basis. This change in presentation to the consolidated cash flow statement does not impact total operating, investing, or financing cash flows. There was no change to the consolidated statement of income or consolidated balance sheet. In accordance with ASC 250, Accounting Changes and Error Corrections, we evaluated the materiality of the errors from quantitative and qualitative perspectives and concluded that the errors were immaterial to the Company’s 2022 audited financial statements. Since these revisions were not material to any prior period financial statements, no amendments to previously filed financial statements are required. Consequently, the Company has corrected these immaterial errors by revising the December 31, 2021 consolidated financial statements presented herein.The tables below present the effect of the financial statement adjustments related to the revision discussed above of the Company’s previously reported financial statements as of and for the periods ended December 31, 2021.The effect of the immaterial correction of an error on our previously filed audited consolidated financial statements as of December 31, 2021 and for the year then ended is as follows: <table border="0" cellpadding="0" cellspacing="0" class="finTable" style="margin-right: 10%;
