Income Taxes
Income Taxes	10.    Income Taxes The estimated annual effective income tax rate for the current quarter and the prior year quarter was approximately 0% for both periods, resulting in an income tax benefit of $0 for both periods. For both the current quarter and the prior year quarter, the federal statutory rate differed from the effective tax rate due to the recording of a valuation allowance against the benefit that would have otherwise been recognized, as it was considered not more likely than not that the net operating losses generated during each period will be utilized in future periods.
