Error Correction [Text Block] | NOTE S—REVISION OF PREVIOUSLY ISSUED CONSOLIDATED FINANCIAL STATEMENTS Due to errors discovered in the Company’s 2020 and 2021 tax provisions, the Company revised certain previously issued disclosures related to the components of its deferred tax assets and liabilities and valuation allowance as of December 31, 2021 and 2020. Additionally, the Company has revised the reconciliation of its income tax rate computed using the federal statutory rate for the year ended December 31, 2021. The errors related primarily to the calculation of available net operating loss carryforwards and to stock based compensation. Since the Company provided a full valuation allowance on its net deferred tax assets, there was no impact to the Consolidated Balance Sheet as of December 31, 2021 and the consolidated statements of operations, stockholders’ equity and cash flows as of and for the year ended December 31, 2021. The Company further reviewed its disclosure of the rate reconciliation and deferred tax calculation along with the valuation allowance of its net deferred tax assets. Other items that were corrected in the disclosure included allowance for doubtful accounts, equipment and leasehold improvements and operating lease liability along with the associated operating lease ROU assets. The below table summarizes the revisions to the reconciliation of our income tax rate computed using the federal statutory rate to our actual income tax rate for the year ended December 31, 2021:
