Income Tax Disclosure [Abstract]

Income Tax Disclosure [Text Block]

Due to the operating losses incurred, we recognized an income tax benefit for all periods presented. The effective tax benefit rates for the three and nine months ended September 30, 2013 included a deferred tax asset valuation allowance due primarily to the inability to recognize tax benefits for all current state net operating losses. The effective tax benefit rates for the three and nine months ended September 30, 2012 included a deferred tax asset valuation for certain state net operating losses.
