Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We recognized a federal income tax benefit for the six months ended June 30, 2016 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. We recognized a minimal state deferred income tax expense for the six months ended June 30, 2015 at an effective rate of 0.2%. We received a state income tax refund of less than $0.1 million during the six months ended June 30, 2016.
