10. Income taxes

There was no provision for income taxes for the three months ended March 31, 2021 or 2020. As of March 31, 2021, the Company’s deferred income tax assets, consisting primarily of net operating loss and tax credit carryforwards, have been fully offset by a valuation allowance. On March 11, 2021, President Biden signed into law the American Rescue Plan Act of 2021; these provisions are not expected to have a material impact on the Company’s income tax provision.
