Income Taxes	9 Months Ended
Sep. 30, 2013
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective tax rate for the three and nine months ended September 30, 2013 was (19.7)% and 7.9%, respectively, compared to 148.4% and 11.5%, respectively, for the three and nine months ended September 30, 2012. The significant items impacting the 2013 rate include a net state tax provision, certain permanent items and a change in the valuation allowance established for the net deferred tax asset balance projected for December 31, 2013. We recognize valuation allowances on deferred tax assets if, based on the weight of the evidence, we determine it is more likely than not such assets will not be realized. Changes in valuation allowances are included in our tax provision in the period of change. In determining whether a valuation allowance is warranted, we evaluate factors such as prior years’ earnings history, expected future earnings, loss carry-back and carry-forward periods, reversals of existing deferred tax liabilities and tax planning strategies that potentially enhance the likelihood of the realization of a deferred tax asset. At September 30, 2013 and December 31, 2012, substantially all of our net deferred tax assets were subject to a valuation allowance. The tax provision for the three month period ended September 30, 2013 by rule is derived by subtracting the tax benefit for the six months ended June 30, 2013 from the tax benefit for the nine months ended September 30, 2013, each of which is computed as a percentage of the year-to-date pre-tax loss, based on the projected annual effective tax rate at the time. Notwithstanding the similar expected annual net tax benefit from period to period, that projected rate decreased substantially from June 30 to September 30, due to the change in expectations of future performance discussed in Note 3, Liquidity, requiring a reversal of a previously recorded benefit. Since our debt recapitalization in July 2011, we have experienced a significant change in ownership of our stock, as measured for federal income tax purposes. On July 25, 2013, we reached the threshold that triggered a change in ownership defined by Internal Revenue Code ("IRC") Section 382. This change will likely limit substantially the use of net operating loss carryovers ("NOLs") generated prior to July 25, 2013 to offset future taxable income. While the Section 382 change may adversely affect future cash flow, it has no impact on our current financial statements. The deferred tax asset resulting from the existing NOLs for which a Section 382 change limits financial statement recognition is already fully offset by a valuation allowance.
