Income Taxes

The Company records income tax expense on an interim basis.  The estimated annual effective income tax rate is adjusted quarterly and items discrete to a specific quarter are reflected in tax expense for that interim period.  The estimated annual effective income tax rate reflects the change in a valuation allowance due to expected current year earnings or loss.  A valuation allowance is established when necessary to reduce deferred tax assets to the amount more likely than not to be realized.  There was no material change in unrecognized tax benefits in the six month period ending June 30, 2011, and the Company does not anticipate a material change in total unrecognized tax benefits within the next 12 months.
