Income Taxes

The Company estimates for each interim reporting period the effective tax rate expected for the full fiscal year and uses that estimated rate in providing for income taxes on a current year-to-date basis. The (benefit) provision for income taxes consisted of the following components for the three and six-month periods ended June 30, 2014 and 2013 (in thousands):

Deferred income taxes are provided to reflect the future tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements. The Company’s deferred tax assets have been reduced by a valuation allowance due to a determination that it is more likely than not that some or all of the deferred assets will not be realized based on the weight of all available evidence. The Company continues to closely monitor and weigh all available evidence, including both positive and negative, in making its determination whether to maintain a valuation allowance. As a result of the significant weight placed on the Company's cumulative negative earnings position, the Company continued to maintain the full valuation allowance against its net deferred tax asset at June 30, 2014.

Internal Revenue Code (“IRC”) Section 382 addresses company ownership changes and specifically limits the utilization of certain deductions and other tax attributes on an annual basis following an ownership change. The Company experienced ownership changes within the meaning of IRC Section 382 during 2008 and 2010 that subjected certain of the Company’s tax attributes, including $923.0 million of federal net operating loss carryforwards, to the IRC Section 382 limitation. These limitations could result in a material amount of existing loss carryforwards expiring unused. None of these limitations resulted in a current federal tax liability at June 30, 2014.

At June 30, 2014 and December 31, 2013, the Company had a liability of approximately $0.1 million and $1.4 million, respectively, for unrecognized tax benefits. Included in the $1.4 million liability for unrecognized tax benefits at December 31, 2013 was $0.1 million for interest and penalties relating to uncertain tax positions.

The Company’s only taxing jurisdiction is the United States (federal and state). The Company’s tax years 2010 to present remain open for federal examination. Additionally, various tax years remain open beginning with tax year 2005 due to federal net operating loss carryforwards. The number of years open for state tax audits varies, depending on the state, but are generally from three to five years. The Company does not expect a significant change in its gross unrecognized tax benefits balance within the next twelve months.
