The SEC subsequently issued Staff Accounting Bulletin No. 118, “Income Tax Accounting Implications of the Tax Cuts and Jobs Act” (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. Under SAB 118, companies are able to record a reasonable estimate of the impacts of the Tax Act if one is able to be determined and report it as a provisional amount during the measurement period. The measurement period is not to extend beyond one year from the enactment date. Impacts of the Tax Act that a company is not able to make a reasonable estimate for should not be recorded until a reasonable estimate can be made during the measurement period. In the three months ended December 31, 2017, the Company revised its estimated annual effective rate to reflect a change in the federal statutory rate from 35.0% to 28.1%. The change in statutory rate was made as a result of the Tax Act. The rate change is administratively effective as of the enactment date and the Company is using a blended rate of 28.1% for its fiscal year ending on June 30, 2018, as prescribed. In addition, in the three months ended December 31, 2017, the Company recognized tax expense related to adjusting its deferred tax balances to reflect the new corporate tax rate. Deferred tax amounts are calculated based on the rates at which they are expected to reverse in the future. The Company is analyzing certain aspects of the Tax Act and refining its calculations which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. The provisional amount recorded related to the re-measurement of the Company’s deferred tax balance was $(20.3) million at December 31, 2017. The Company’s effective tax rates for the three months ended December 31, 2017 and 2016 were 976.2% and 40.1%, respectively. The Company’s effective tax rates for the six months ended December 31, 2017 and 2016 were 4,449.3% and 40.1%, respectively. The effective tax rates for the three and six months ended December 31, 2017 and 2016 were higher than the U.S. statutory rates of 28.1% and 35.0%, respectively, primarily due to income tax expense of $(20.3) million resulting from the adjustment of deferred tax amounts due to enactment of the Tax Act. The Company evaluates its deferred tax assets quarterly to determine if a valuation allowance is required. In making such assessment, significant weight is given to evidence that can be objectively verified, such as recent operating results, and less consideration is given to less objective indicators such as future income projections. After consideration of positive and negative evidence, including the recent history of income, the Company concluded that it is more likely than not that the Company will generate future income sufficient to realize the majority of the Company’s deferred tax assets. As of December 31, 2017 and June 30, 2017 the Company had no unrecognized tax benefits. As discussed in Note 2, the Company adopted ASU 2016-09 beginning July 1, 2017 and upon adoption recognized the excess tax benefits of $1.6 million as an increase to deferred tax assets and a corresponding increase to retained earnings.
