9. Income Taxes

Our effective tax rate is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which we operate. For interim financial reporting, we estimate the annual effective tax rate based on expected taxable income for the full year and record a quarterly income tax provision in accordance with the anticipated annual effective rate and adjust for discrete items. We update the estimates of the taxable income throughout the year as new information becomes available, including year-to-date financial results. This process often results in a change to our expected effective tax rate for the year. When this occurs, we adjust the income tax provision during the quarter in which the change in estimate occurs so that the year-to-date provision reflects the expected annual effective tax rate. Significant judgment is required in determining our effective tax rate and in evaluating our tax positions.

We apply the provisions of ASC Subtopic 740-10 in accounting for uncertainty in income taxes. In accordance with ASC Subtopic 740-10, we recognize a tax benefit associated with an uncertain tax position when, in our judgment, it is more likely than not that the position will be sustained upon examination by a taxing authority. For a tax position that meets the more-likely-than-not recognition threshold, we initially and subsequently measure the tax benefit as the largest amount that we judge to have a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority. Our liability associated with unrecognized tax benefits is adjusted periodically due to changing circumstances, such as the progress of tax audits, case law developments and new or emerging legislation. Such adjustments are recognized entirely in the period in which they are identified. Our effective tax rate includes the net impact of changes in the liability for unrecognized tax benefits and subsequent adjustments as considered appropriate by management.

A reconciliation of the unrecognized tax benefit under ASC Subtopic 740 follows (in thousands):

	November 1, 2014			February 1, 2014
Unrecognized tax benefits - beginning of year	$	1,539		$	2,708
Gross increases - tax positions in prior period		121			245
Gross decreases - tax positions in prior period		(168	)		(964	)
Gross increases - tax positions in current period		128			277
Settlements		(119	)		(517	)
Lapse of statute of limitations		(197	)		(210	)
Unrecognized tax benefits - end of year	$	1,304		$	1,539

We file income tax returns in the U.S. federal and various state jurisdictions. Generally, we are not subject to changes in income taxes by the U.S. federal taxing jurisdiction for years prior to Fiscal 2012 or by most state taxing jurisdictions for years prior to Fiscal 2011.
