NOTE 9 — INCOME TAXES

The Company calculates its quarterly tax provision consistent with the guidance provided by ASC 740-20, "Interim Income Tax Accounting," whereby the Company forecasts its estimated annual effective tax rate and then applies that rate to its year-to-date pre-tax book income (loss). The Company's tax expense for the three months ended March 31, 2012 was not significant, and represented interest expense related to its reserves for uncertain income tax positions. The Company recorded a tax benefit of $0.9 million for the three months ended March 31, 2011. The tax benefit was primarily due to the Company's ability to carry back its anticipated 2011 federal income tax loss to the prior two tax years.

Based upon the weight of available evidence, which includes the Company's historical operating performance, reported cumulative net losses since inception and expected continuing net loss, the Company has established and continues to maintain a full valuation allowance against its deferred tax assets as the Company does not currently believe that realization of those assets is more likely than not.
