Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes Our effective tax rate for the quarter ended March 31, 2015 was (12.7%). The rate is primarily comprised of the effect of the Texas margin tax, due to our valuation allowance for federal income tax purposes being applied against any potential deferred tax asset which would have ordinarily resulted. While we do not expect to receive a benefit for the full year, the negative effective tax rate is determined by applying the guidance in ASC 740-270. We expect to owe Texas margin tax for the full year 2015. We were not subject to a valuation allowance for federal taxes in the prior year comparable quarter.
