We determine our estimated annual effective tax rate at the end of each interim period based on full-year forecasted
pre-tax
income and facts known at that time. The estimated annual effective tax rate is applied to the
year-to-date
pre-tax
income at the end of each interim period with the cumulative effect of any changes in the estimated annual effective tax rate being recorded in the fiscal quarter in which the change is determined. The tax effect of significant unusual items is reflected in the period in which they occur.
During the three months ended May 2, 2020,
we
recognized an income tax benefit of approximately $118,000.
The effective tax rate in this period was directly impacted by a reduction in our forecasted operating results for fiscal 2021 and a
$78,000
tax benefit related to the expiration of the statute of limitations on previously uncertain tax positions
. During the three months ended May 4, 2019,
we
recognized an income tax expense of approximately $400,000. The effective tax rate in this period was directly impacted by a $53,000 tax benefit related to the expiration of the statute of limitations on a previously uncertain tax position and a $97,000 windfall tax benefit related to
our
stock.
We maintain a valuation allowance on some of our deferred tax assets in certain jurisdictions. A valuation allowance is required when, based upon an assessment of various factors, including recent operating loss history, anticipated future earnings, and prudent and reasonable tax planning strategies, it is more likely than not that some portion of the deferred tax assets will not be realized.
Unrecognized tax benefits represent the difference between tax positions taken or expected to be taken in a tax return and the benefits recognized for financial reporting purposes. As of May 2, 2020,
our
 
cumulative unrecognized tax benefits totaled $319,000 compared to $362,000 as of January 31, 2020. Besides the expiration of the statute of limitations on a previously uncertain tax position, there were no other developments affecting
our
unrecognized tax benefits during the quarter ended May 2, 2020.
