Schedule of Unrecognized Tax Benefits Roll Forward [Table Text Block]

As of December 31, 2013, we have not recognized any liability for uncertain tax positions, because of our full valuation allowance. We will recognize interest and penalties related to these positions, should such costs be assessed. As of December 31, 2013, we have not recognized interest and penalties. The recognition of unrecognized tax benefits would not affect our effective tax rate because the tax benefit would be offset by an increase in our valuation allowance.
