Income Taxes

11. Income taxes

For the three months ended June 30, 2022 and 2021, we recorded net income tax expense of $0.09 million and $0.12 million, respectively and for the six months ended June 30, 2022 and 2021, we recorded net income tax expense of $0.17 million and $0.10 million, respectively, all of which were lower than the statutory rate of 21%, primarily due to a valuation allowance established against the U.S. deferred tax assets.

We have had no material change in our unrecognized tax benefits since December 31, 2021. We recognize accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. As of June 30, 2022 and December 31, 2021, we had no accrued interest or penalties related to unrecognized tax benefits.
