Income Taxes	Note 11 – Income Taxes On December 22, 2017, the U.S. government enacted the Tax Act. The legislation is broad and complex and significantly revises the U.S. corporate income tax system by, among other things, reducing the current corporate federal income tax rate to 21% from 35%, adopting a modified territorial regime and imposing a one-time transitional tax on deemed repatriated earnings of foreign subsidiaries. The rate reduction is effective January 1, 2018 resulting in a U.S. statutory rate for fiscal year 2018 of 24.5% and 21% for subsequent fiscal years. At June 30, 2018, we have not completed our accounting related to the initial tax effects of enactment of the Tax Act; however, in certain cases, as described below, we have made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. The final transition impact of the Tax Act may differ, possibly materially, from the estimates provided, due to, among other things, changes in interpretations of the Tax Act, regulatory guidance that may be issued, any legislative action to address questions that arise because of the Tax Act, any changes in accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates we have utilized to calculate the impact. The SEC has issued Staff Accounting Bulletin No. 118, which was codified in March 2018 under ASU 2018-05, that would allow for a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related tax impacts. We currently anticipate finalizing and recording any resulting adjustments within the one year time period provided. Based on an initial assessment, a provisional discrete tax benefit of $4.3 million and $3.0 million has been recorded in the three months ended December 31, 2017 and March 31, 2018, respectively, related to the re-measurement of U.S. net deferred tax liabilities at the lower enacted corporate tax rate and other effects of enactment of the Tax Act. While other deferred tax assets and liabilities will also be reduced, such reduction is expected to be offset by changes to our U.S. valuation allowance. The one-time transition tax is based on post-1986 earnings and profits (E&P) that we previously deferred from U.S. income taxes. At present, we do not anticipate a material impact on the income statement from the one-time transition tax and therefore have recorded a provisional amount of $0 as of June 30, 2018. We have not yet completed our calculation of the total post-1986 E&P of our foreign entities, and as such the calculation is subject to further refinement. During the three months ended March 31, 2018 we classified the CGD Services business as discontinued operations and subsequently completed the sale during the three months ended June 30, 2018. ASC 740-20 requires total income tax expense or benefit to be allocated among continuing operations, discontinued operations, extraordinary items, other comprehensive income and items charged directly to shareholders’ equity. For the nine months ended June 30, 2018, we recognized a combined U.S. gain from discontinued operations and other comprehensive income and a loss from U.S. continuing operations and therefore recorded tax expense of $0.5 million to discontinued operations with an offsetting $0.5 million benefit to continuing operations. Income tax expense recognized on pre-tax losses from continuing operations for the nine months ended June 30, 2018 resulted in an effective tax rate of negative 37.5% which differs from the effective tax rate of negative 132.3% for the year ended September 30, 2017 primarily due to the difference in jurisdictional mix, the overall level of pre-tax income (loss) and discrete tax benefits resulting from enactment of the Tax Act. The effective tax rate for the nine months ended June 30, 2018 differs from the U.S. statutory tax rate of 24.5% 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, offset by discrete tax benefits resulting from the impact of the Tax Act. Income tax expense recognized on pre-tax income from continuing operations for the three months ended June 30, 2018 resulted in an effective tax rate of 120.8% as compared to negative 737.0% for the three months ended June 30, 2017. The year-over-year comparison of effective tax rates is not meaningful due to the impact of applying the accounting guidance provided by ASC 740-270-45-8 in order to determine tax expense from discontinued operations. The amount of net unrecognized tax benefits was $5.6 million as of June 30, 2018 and $6.5 million as of September 30, 2017, exclusive of interest and penalties. At June 30, 2018, the amount of net unrecognized tax benefits from permanent tax adjustments that, if recognized, would favorably impact the effective rate was $2.8 million. During the next 12 months, it is possible that resolution of reviews by taxing authorities, both domestic and international, could be reached with respect to approximately $2.8 million of the net unrecognized tax benefits depending on the timing of examinations and expiration of statute of limitations, either because our tax positions are sustained or because we agree to their disallowance and pay the related income tax. We are subject to ongoing audits from various taxing authorities in the jurisdictions in which we do business. As of June 30, 2018, the years open under the statute of limitations in significant jurisdictions include fiscal years 2015-2017 in the U.S. We believe we have adequately provided for uncertain tax issues that have not yet been resolved with federal, state and foreign tax authorities. As of June 30, 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 June 30, 2018, a total valuation allowance of $72.7 million has been established for U.S. net deferred tax assets, certain foreign operating losses and other foreign assets.
