We have determined that it is more likely than not that our deferred tax assets will be realized, principally through anticipated taxable income in future tax years. As a result, we have determined that establishing a valuation allowance on our deferred tax assets is not necessary.

The tax effects from an uncertain tax position can be recognized in our consolidated financial statements, only if the position is more likely than not to be sustained on audit, based on the technical merits of the position. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. The following table sets forth changes in our total gross unrecognized tax benefit liabilities, excluding accrued interest, for the years ended December 31, 2014 and 2013:

Balance as of December 31, 2012	$	140,000
Tax positions related to 2013:
Additions		53,000
Reductions		—

Balance as of December 31, 2013		193,000
Tax positions related to current year:
Additions		23,000
Reductions		(160,000	)

Balance as of December 31, 2014	$	56,000

The $56,000 of unrecognized tax benefits as of December 31, 2014 includes amounts which, if ultimately recognized, will reduce our annual effective tax rate. It is included in Other Long-Term Liabilities on the accompanying consolidated balance sheets.

Our policy is to accrue interest related to potential underpayment of income taxes within the provision for income taxes. The liability for accrued interest as of December 31, 2014 and 2013 was not significant. Interest is computed on the difference between our uncertain tax benefit positions and the amount deducted or expected to be deducted in our tax returns.

We are subject to income taxes in the U.S. federal jurisdiction and various state jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply.

With few exceptions, we are no longer subject to U.S. federal, state or local income tax examinations by tax authorities for the years before 2010.
