Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes Due to the pre-tax operating loss incurred, we recognized a federal income tax benefit for the three and six months ended June 30, 2015 at the statutory rate of 35%; however, the federal tax benefit was fully offset by a valuation allowance against our net deferred tax assets. We considered both the positive and negative evidence in determining that it was more likely than not that some portion or all of our deferred tax assets will not be realized, primarily as a result of recent cumulative losses. The income tax provision also includes a minimal deferred state income tax expense resulting in a combined effective tax rate of 0.2% for the six months ended June 30, 2015. The significant difference between our combined federal and state statutory rate of 35.7% and our estimated effective tax of 0.2% is due primarily to the valuation allowance placed against our deferred tax assets. We recognized an income tax benefit for six months ended June 30, 2014 at an effective rate of 34.2% which reflects the adverse effects of losses incurred in jurisdictions for which we may not realize a tax benefit and therefore recorded a valuation allowance against the related deferred tax assets.

Income Taxes

Due to the pre-tax operating loss incurred, we recognized a federal income tax benefit for the three and six months ended June 30, 2015 at the statutory rate of 35%; however, the federal tax benefit was fully offset by a valuation allowance against our net deferred tax assets. We considered both the positive and negative evidence in determining that it was more likely than not that some portion or all of our deferred tax assets will not be realized, primarily as a result of recent cumulative losses. The income tax provision also includes a minimal deferred state income tax expense resulting in a combined effective tax rate of 0.2% for the six months ended June 30, 2015. The significant difference between our combined federal and state statutory rate of 35.7% and our estimated effective tax of 0.2% is due primarily to the valuation allowance placed against our deferred tax assets.

We recognized an income tax benefit for six months ended June 30, 2014 at an effective rate of 34.2% which reflects the adverse effects of losses incurred in jurisdictions for which we may not realize a tax benefit and therefore recorded a valuation allowance against the related deferred tax assets.
