We classify reserves for tax uncertainties within accrued expenses and deferred credits and other in our Consolidated Condensed Balance Sheets, separate from any related income tax payable or deferred income taxes. Reserve amounts relate to any potential income tax liabilities resulting from uncertain tax positions and potential interest or penalties associated with those liabilities.

Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. Due to recent impairments and ongoing losses from continuing operations, we project that future reversals of taxable temporary differences are no longer sufficient to provide adequate taxable income to realize our deferred tax assets. As such, we have established a valuation allowance against the federal deferred tax assets that are not projected to be realizable.

The effective tax rate for the three months ended March 31, 2014 and 2013 was 29.6% and 62.4%, respectively. The effective tax rate benefit in the first quarter of 2014 was unfavorably impacted by an increase in the federal valuation allowance against 2014 losses from continuing operations which were not tax benefitted, partially offset by a tax benefit from the reversal of uncertain state tax positions. The effective tax rate benefit in the first quarter of 2013 was favorably impacted by the tax benefits from a capital loss resulting from a tax election made for U.S. federal income tax purposes.

We file income tax returns, including returns for our subsidiaries, with federal, state, and foreign jurisdictions. We are under regular and recurring audit by the Internal Revenue Service on open tax positions, and it is possible that the amount of the liability for unrecognized tax benefits could change during the next 12 months.
