The Company reviews the likelihood that it will realize the benefit of its deferred tax assets and, therefore, the need for valuation allowances on a quarterly basis. There is no corresponding income tax benefit recognized with respect to losses incurred and no corresponding income tax expense recognized with respect to earnings generated in jurisdictions with a valuation allowance. This causes variability in the Company’s effective tax rate. The Company will maintain the valuation allowances until it is more likely than not that the net deferred tax assets will be realized. As of September 30, 2014, the Company’s gross uncertain tax benefits totaled $1,088. As of September 30, 2014, none of the Company’s uncertain tax benefits, including related accrued interest and penalties, would affect the Company’s effective tax rate if recognized.

The Company’s quarterly provision for income taxes is based on an estimated effective annual income tax rate. The Company’s quarterly provision for income taxes also includes the tax impact of certain unusual or infrequently occurring items, if any, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur.
