Income Tax Disclosure [Text Block] |
The components of our deferred tax assets (“DTAs”) as of December 31, 2022 and 2021 are summarized in the following table:
footnote Current accounting standards require a valuation allowance against DTAs if, based on the weight of available evidence, it is more likely than not that some or all of the DTAs may not be realized. Due to the uncertainty surrounding the realization of these DTAs in future tax returns, all of the DTAs have been fully offset by a valuation allowance as of December 31, 2022 and 2021.
In assessing the realizability of DTAs, management considers whether it is more likely than not that some portion or all of the DTAs will not be realized. The ultimate realization of DTAs is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carryback and carryforward periods) and projected future taxable income in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the DTAs are deductible, management believes it is more likely than not that the Company will not realize the benefits of these deductible differences or tax carryforwards as of December 31, 2022.
As of December 31, 2022 and 2021, we had U.S. net operating loss carryforwards of $175,127,244 and $168,776,440, respectively. As of December 31, 2022 and 2021, we also had state net operating loss carryforwards of $20,068,842. The state net operating loss carryforwards will begin expiring in 2027.
There were no expirations of U.S. NOL carryforwards during 2022 or 2021. U.S. R&D credit carryforwards of $5,350 and $0 expired during 2022 and 2021, respectively.
The details of our U.S. net operating loss and federal R&D credit carryforward amounts and expiration dates as of December 31, 2022 are summarized in the following table:
Under Sections 382 and 383 of the Internal Revenue Code (“IRC”) of 1986, as amended, the utilization of U.S. net operating loss and R&D tax credit carryforwards may be limited under the change in stock ownership rules of the IRC. The Company completed a Section 382 analysis through December 31, 2022 and believes that a Section 382 ownership change has not occurred.
