Any refinements made due to subsequent information that affects the estimated annual effective income tax rate are reflected as adjustments in the current period. Separate effective income tax rates are calculated for net income from continuing operations and any other separately reported net income items, such as discontinued operations.         The income tax provision for the three and six months ended June 30, 2013 and 2012 results in an effective tax rate that has an unusual relationship to the Company's pretax income (loss). This is due to an increase in the federal and state valuation allowances on the Company's deferred tax assets as discussed below. The income tax provision for the six months ended June 30, 2013 also includes a state/local income tax provision of $0.2 million, offset by a benefit of $0.6 million related to the reversal of unrecognized tax benefits, further discussed below.         The difference between the effective rate and the statutory rate is attributed primarily to permanent items not deductible for income tax purposes and the treatment of certain items in accordance with the rules for interperiod tax allocation. As a result of our net operating losses and the net deferred tax asset position (after exclusion of certain deferred tax liabilities that generally cannot be offset against deferred tax assets), we expect to continue to provide for a full valuation allowance against all of our net federal and our net state deferred tax assets.         For income tax purposes we amortize or depreciate certain assets that have been assigned an indefinite life for book purposes. The incremental amortization or depreciation deductions for income tax purposes result in an increase in certain deferred tax liabilities that cannot be used as a source of future taxable income for purposes of measuring our need for a valuation allowance against the net deferred tax assets. Therefore, we expect to record non-cash deferred tax expense as we amortize these assets for tax purposes. The increase in the valuation allowance for the six months ended June 30, 2013 and 2012 was $1.7 million and $1.4 million, respectively.         During the six months ended June 30, 2013, the Company released unrecognized tax benefits of $0.6 million, which included $0.2 million of accrued interest, as a result of the lapse in the statute of limitations for the original tax return years and subsequent loss carryback periods. At June 30, 2013, no unrecognized tax benefits remain. The company does not anticipate any significant changes to the unrecognized tax benefits within the next twelve months.         The Company and its subsidiaries file a consolidated US federal income tax return and consolidated and separate income tax returns in various state and local jurisdictions. We are no longer subject to US federal or state and local income tax examinations by tax authorities for years before 2004. </div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for income taxes.
