           Income taxes
 
We recorded a provision for income taxes of
$1.0
million and
$1.3
million for the
three
months ended
April 29, 2017
and
April 30, 2016,
respectively.  The decrease in tax expense is primarily attributable to lower profitability in taxable jurisdictions in the
first
quarter of fiscal year
2018
as compared to the same period in fiscal year
2017
and changes in tax reserves. During the
three
months ended
April 29, 2017
and
April 30, 2016,
we were unable to reasonably project our annual effective tax rate, and therefore computed our provision for income taxes based on year-to-date actual financial results. Included in our provision for income taxes are foreign exchange gains or losses on unsettled income tax liabilities
