6. Income Taxes

 

The Company recorded no consolidated income tax benefit (expense) for the three and nine months ended September 30, 2021 and 2020. The Company has recorded a valuation allowance to reduce its net deferred tax asset to an amount that is more likely than not to be realized in future years. Accordingly, the tax provision that would have been recognized in the three and nine months ended September 30, 2021 was offset by changes in the valuation allowance. During the three and nine months ended September 30, 2021, the Company had no material changes in uncertain tax positions.
