Income Taxes

The Company's anticipated annual tax rate is impacted primarily by the amount of taxable income associated with each jurisdiction in which its income is subject to income tax, permanent differences between the financial statement carrying amounts and tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

Section 382 of the Internal Revenue Code ("IRC") imposes limitations on the use of U.S. federal net operating losses (“NOLs”) upon a more than 50% change in ownership in the Company (ad defined in the IRC) within a three-year period. In connection with its at-the-market equity offering, the Company underwent a Section 382 ownership change on March 25, 2022. As a result, utilization of the Company’s NOL’s and certain unrealized losses are limited on an annual basis. If the Section 382 annual limitation amount is not fully utilized in a particular tax year, then the unused portion from that tax year is added to the Section 382 annual limitation in subsequent years. The Company’s annual limitation under Section 382 is estimated to be approximately $1.3 million.

The Company incurred no net income tax expense or benefit for the three months ended March 31, 2022 and 2021. The effective tax rate for the three months ended March 31, 2022, and 2021, was 0.0% and 0.0%, respectively. The effective tax rates differed from the statutory rate during each period primarily due to changes in the valuation allowance established to offset net deferred tax assets. The effective tax rate for the three months ended March 31, 2022 was less than the U.S. statutory rate which was due to the current year tax loss, offsetting the change in valuation allowance.
