In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income or reversal of deferred tax liabilities during the periods in which those temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. A valuation allowance was recorded against the majority of the net deferred tax assets totaling $21,906,000 at January 31, 2016. At October 31, 2016, the Company determined that it was more-likely-than-not to realize the majority of its deferred tax assets, and therefore released its valuation against those assets resulting in a benefit to income taxes. The Company has left a partial valuation allowance of $515,000 against certain state deferred tax assets that the Company does not believe it is more-likely-than-not to realize. A valuation allowance was recorded against the majority of the net deferred tax assets totaling $21,906,000 at January 31, 2016. At January 31, 2017, the Company has net operating loss carryforwards of approximately $16,879,000 for federal and $34,145,000 for state income tax purposes, expiring at various dates through January 31, 2035.

The following table summarizes the activity related to our gross unrecognized tax benefits from February 1, 2015 to January 31, 2017 (in thousands):

At January 31, 2017, the Company’s unrecognized tax benefits associated with uncertain tax positions were $29,000, of which $19,000 if recognized, would favorably affect the effective tax rate.

The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense which is consistent with the recognition of the items in prior reporting. The Company had recorded a liability for interest and penalties related to unrecognized tax benefits of $7,000 at January 31, 2017, and January 31, 2016. In 2016, the Company closed its IRS examination for its tax return for the year ended January 31, 2013 with no changes. The years ended January 31, 2012 , January 31, 2014 and subsequent years remain open for examination by the IRS and state tax authorities. The Company is not currently under IRS or state examination.

During 2015, the Company completed Texas income tax examinations of the tax years ending January 31, 2010 and 2011. The examination did not materially impact the Consolidated Statements of Operations.

The specific timing of when the resolution of each tax position will be reached is uncertain. As of January 31, 2017, it is reasonably possible that unrecognized tax benefits will decrease by $7,000 within the next 12 months due to the expiration of the statute of limitations.
