Due to the complexity of the Tax Act, the SEC issued guidance in SAB 118 which clarified the accounting for income taxes under ASC 740 if certain information was not yet available, prepared or analyzed in reasonable detail to complete the accounting for income tax effects of the Tax Act. SAB 118 provided for a measurement period of up to one year after the enactment of the Tax Act, during which time the required analyses and accounting must be completed. During fiscal year 2018, we recorded provisional amounts for the income tax effects of the changes in tax law and tax rates, as reasonable estimates were determined by management during this period. During the first quarter of fiscal year 2019, we did not adjust provisional amounts recorded in the prior fiscal year and the SAB 118 measurement period subsequently ended on December 22, 2018.

Effective Tax Rate During interim periods, the Company generally utilizes the estimated annual effective tax rate method which involves the use of forecasted information. Under this method, the provision is calculated by applying an estimate of the annual effective tax rate for the full fiscal year to “ordinary” income or loss (pretax income or loss excluding unusual or infrequently occurring discrete items) for the reporting period. For the three-month period ended December 31, 2018, the Company believes it is more appropriate to use a blend of the discrete effective tax rate method and the estimated annual effective tax rate method to calculate income tax expense for the period. The Company determined that since small changes in estimated “ordinary” income for U.S. operations would result in significant changes in the worldwide estimated annual effective tax rate, the discrete tax rate method should be utilized to determine a more reliable estimate of U.S. income tax expense for the period. Income tax expense recognized on pre-tax losses from continuing operations for the three months ended December 31, 2018 resulted in an effective tax rate of negative 31% which differs from the U.S. statutory tax rate of 21% primarily due to the jurisdictional mix of pre-tax income (loss) and U.S. losses for which no tax benefit can be realized due to a valuation allowance. The effective tax rate for the three months ended December 31, 2018 differs from the effective tax rate of negative 6% and positive 48% for the three months ended December 31, 2017 and the year ended September 30, 2018, respectively, primarily due to differences in the jurisdictional mix of pre-tax income (loss), partially offset by discrete benefits resulting from the enactment of the Tax Act. Deferred Tax Balances As of December 31, 2018, we maintained a valuation allowance against U.S. deferred tax assets as realization of such assets does not meet the more-likely-than-not threshold required under accounting guidelines. We will continue to assess the need for a valuation allowance on deferred tax assets by evaluating positive and negative evidence that may exist. Through December 31, 2018, a total valuation allowance of $79.3 million has been established for U.S. net deferred tax assets, certain foreign operating losses and other foreign assets.
