Note 9—Income Taxes


At March 31, 2014 and December 31, 2013, the Company had net deferred tax assets that were fully offset by a valuation allowance, as management believes that it is not more likely than not that the Company will realize the benefits of the deductible differences. The deferred tax assets at both March 31, 2014 and December 31, 2013 are principally the result of federal and state net operating loss carryforwards of approximately $139 million. These net operating loss carryforwards will expire at various dates through 2034, if unused.


During the three months ended March 31, 2014 and 2013, the Company had no material changes in uncertain tax positions.
