Income Tax Disclosure [Abstract] |
Income Taxes | Note 9 — Income Taxes Ordinarily, the effective tax rate at the end of an interim period is calculated using an estimate of the annual effective tax rate expected to be applicable for the full fiscal year. However, when a reliable estimate cannot be made, the Company computes its provision for income taxes using the actual effective tax rate (discrete method) for the year-to-date period. The Company’s effective tax rate is highly influenced by the amount of its research and development tax credits. A small change in estimated annual pretax income (loss) can produce a significant variance in the annual effective tax rate given the Company’s expected amount of research and development tax credits. This variability provides an unreliable estimate of the annual effective tax rate. As a result, and in accordance with the authoritative guidance for accounting for income taxes in interim periods, the Company has computed its provision for income taxes for the three and six months ended September 30, 2016, by applying the actual effective tax rate to the year-to-date income for the three-month and six-month periods. Future realization of existing deferred tax assets ultimately depends on future profitability and the existence of sufficient taxable income of appropriate character (for example, ordinary income versus capital gains) within the carryforward period available under tax law. In the event that the Company’s estimate of taxable income is less than that required to utilize the full amount of any deferred tax asset, a valuation allowance is established which would cause a decrease to income in the period such determination is made. For the three and six months ended September 30, 2016, the Company’s gross unrecognized tax benefits increased by $1.0 million and $2.1 million, respectively. In the next twelve months it is reasonably possible that the amount of unrecognized tax benefits will not change significantly.
