Income Taxes [Abstract]
Income Taxes	Note 5. Income Taxes We did not provide for income taxes in 2013 because we have projected a net loss for the full year 2013. Interest expense and penalties related to unrecognized tax benefits were immaterial for 2013 and 2012.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
