For 2012, 2011 and 2010, the Company performed a detailed reconciliation of its federal and state taxes payable and receivable accounts along with its federal and state deferred tax asset and liability accounts. As a result of this detailed analysis, the Company recorded an increase in the 2013 state income tax provision of $393,000, for the 2012 reconciliation, and $162,000 additional provision in 2012 for the 2011 reconciliation. No adjustment was necessary for the 2010 reconciliation. The Company considers this reconciliation process to be an annual control.

The Company is required to establish a valuation allowance for deferred tax assets if, based on the weight of available evidence, 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 during the periods in which those temporary differences become deductible. Management considers the projected future taxable income and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income in the periods which the deferred tax assets are deductible, management believes that a valuation allowance is not required, as it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets.

The Company’s U.S. federal returns remain open to examination for 2010 through 2012 and U.S. state jurisdictions are open for periods ranging from 2009 through 2012.

The Company does not believe that it has any significant uncertain tax positions at December 31, 2013, nor is this expected to change within the next twelve months due to the settlement and expiration of statutes of limitation.

The Company did not have any accrued interest or penalties associated with any unrecognized tax benefits nor was any interest expense recognized during the years ended December 31, 2013, 2012 and 2011.
