Income Taxes [Abstract]  
Income Taxes
We review the need to establish a deferred tax asset valuation allowance on a quarterly basis. We analyze several factors, among which are the severity and frequency of operating losses, our capacity for the carryback or carryforward of any losses, the expected occurrence of future income or loss and available tax planning alternatives. Based on our analysis and the level of cumulative operating losses, we have reduced our benefit from income tax through the recognition of a valuation allowance.
