INCOME TAXES INCOME TAXES
Our effective income tax rate for the first quarter of fiscal 2021 was 16.6%, as compared to 22.0% in the corresponding period in fiscal 2020. The decrease was primarily due to a one-time tax benefit from foreign income tax refunds and a change in the geographic mix of income.
We and our subsidiaries are subject to U.S. federal, state, and foreign income taxes. Currently, we are in different stages of multiple year examinations by various state and foreign taxing authorities. While we believe our reserves are more likely than not to be adequate to cover final resolution of all open tax matters, it is reasonably possible that future obligations related to these matters could arise.
Unrecognized tax benefits of $48.3 million and $47.8 million as of the end of the first quarter of fiscal 2021 and fiscal year end 2020, respectively, if recognized, would favorably affect the effective income tax rate in future periods. As of the end of the first quarter of fiscal 2021 and fiscal year end 2020, we accrued interest and penalties of $10.6 million and $9.6 million, respectively. Although timing of the resolution and/or closure of audits is not certain, we do not believe that our gross unrecognized tax benefits would materially change in the next twelve months.
