The effective tax rate for the three months ended August 30, 2020, was higher than the statutory federal income tax rate of 21% primarily due to the generation of federal & state research and development (“R&D”) credits and movements of the valuation allowance recorded against certain deferred tax assets, partially offset by the impact of state taxes and stock based compensation.

Included in the balance of unrecognized tax benefits as of August 30, 2020 and May 31, 2020, is $0.8 million and $0.7 million, respectively, of tax benefits that, if recognized, would result in an adjustment to the Company’s effective tax rate.
