Note 10 - Income Taxes

The Company has accumulated net losses since inception and has not recorded an income tax provision or benefit during the years ended December 31, 2020 and 2019.

​

A reconciliation of the statutory U.S. federal rate to the Company’s effective tax rate is as follows:

​

​

The components of the net deferred tax asset as of December 31, 2020 and 2019 are the following ($ in thousands):

​

​

The Company has determined, based upon available evidence, that it is more likely than not that the net deferred tax asset will not be realized and, accordingly, has provided a full valuation allowance against its net deferred tax assets as of December 31, 2020 and 2019. A valuation allowance of approximately $67.1 million and $42.6 million, respectively, was recorded for the years ended December 31, 2020 and 2019.

As of December 31, 2020, the Company had federal and state net operating loss carryforwards of approximately $133.3 million and $263.6 million, respectively. Approximately $109.6 million and $43,000 of the federal and state net operating loss carryforwards, respectively, can be carried forward indefinitely. The remaining $23.7 million and $263.5 million of federal and state net operating loss carryforwards will begin to expire, if not utilized, by 2035 and 2029, respectively. As of December 31, 2020, the Company had federal and state income tax credits of approximately $4.8 million and $1.2

million, respectively, which will begin to expire in 2033. Under the provisions of Section 382 of the Internal Revenue Code, a corporation that undergoes an “ownership change”, as defined therein, is subject to limitations on its use of pre-change NOLs and income tax credits carryforwards to offset future tax liabilities. The Company is currently evaluating the impact of Section 382 on its tax attributes. The Company has recorded a full valuation allowance on all of its deferred tax assets as it believes that it is more likely than not that the deferred tax assets will not be realized regardless of whether an “ownership change” has occurred.

There are no significant items determined to be unrecognized tax benefits taken or expected to be taken in a tax return, in accordance with ASC 740 “Income Taxes” (“ASC 740”), which clarifies the accounting for uncertainty in income taxes recognized in the financial statements, that have been recorded on the Company’s financial statements for the period ended December 31, 2020. The Company does not anticipate a material change to unrecognized tax benefits in the next twelve months.

Additionally, ASC 740 provides guidance on the recognition of interest and penalties related to income taxes. There were no interest or penalties related to income taxes that have been accrued or recognized as of and for the period ended December 31, 2020.

The federal and state tax returns for the years ended December 31, 2017, 2018, and 2019 are currently open for examination under the applicable federal and state income tax statutes of limitations.

In response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act ("CARES Act") was signed into law on March 27, 2020. The CARES Act, among other things, includes tax provisions relating to refundable payroll tax credits, deferment of employer's social security payments, net operating loss utilization and carryback periods and modifications to the net interest deduction limitations. The CARES Act did not have a material impact on the Company’s income tax provision for 2020. The Company will continue to evaluate the impact of the CARES Act on its financial position, results of operations and cash flows.

On December 27, 2020, the President of the United States signed the Consolidated Appropriations Act, 2021 (“Consolidated Appropriations Act”) into law. The Consolidated Appropriations Act is intended to enhance and expand certain provisions of the CARES Act, allows for the deductions of expenses related to the Payroll Protection Program funds received by companies, and provides an update to meals and entertainment expensing for 2021. The Consolidated Appropriations Act did not have a material impact to the Company’s income tax provision for 2020.
