Basis of Presentation And Recently Issued Accounting Pronouncements |
| In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments necessary for a fair presentation of operating results for the interim periods presented. Adjustments consist of normal and recurring accruals. The consolidated financial statements are presented in accordance with the requirements of Form 10-Q and consequently do not include all disclosures required for annual financial statements presented in conformity with U.S. generally accepted accounting principles (GAAP). For further information, refer to the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended September 30, 2017. Certain prior year amounts have been reclassified to conform to current year presentation.
On December 22, 2017, the U.S. government enacted tax reform, the Tax Cuts and Jobs Act (the “Act”), which made comprehensive changes to federal income tax laws by moving from a global to a modified territorial tax regime. The Act includes a reduction of the U.S. corporate income tax rate from 35 percent to 21 percent along with the elimination of certain deductions and credits, and a one-time “deemed repatriation” of accumulated foreign earnings. In the first fiscal quarter, the Company recognized a net tax benefit of $43 ($0.07 per share) due to impacts of the Act, consisting of a $98 benefit on revaluation of net deferred income tax liabilities to the lower tax rate, and $185 of expense for the tax on deemed repatriation of accumulated foreign earnings and withholding taxes partially offset by $130 accrued in previous periods for the planned repatriation of non-U.S. cash. Subsequent to the enactment of the Act, the U.S. Treasury Department and the Internal Revenue Service issued additional guidance, particularly with respect to the calculation of the tax on deemed repatriation of accumulated foreign earnings. As a result of the additional guidance and actions taken in the third fiscal quarter, the Company updated its initial estimates and recognized a benefit of $150 ($0.24 per share), primarily related to an increase in foreign tax credit carryforwards. These updates resulted in a net tax benefit due to the impacts of the Act of $193 ($0.30 per share) for the nine months ended June 30, 2018. The Company continues to review the impacts of the Act and subsequent interpretations. Given its complexities, the ultimate effects on repatriation cost and other tax items may differ from these provisional amounts due to additional regulatory guidance expected to be issued and further evaluation of the Company’s actions, assumptions and interpretations. The effective tax rate for full year 2018 is currently expected to be approximately 19 percent, which includes 7 percentage points of benefit from the Act. In 2019 and thereafter, the tax rate is expected to be approximately 25 percent. In February 2018, the FASB issued updates to ASC 220, Comprehensive Income, which permit reclassification of stranded tax effects resulting from the Act from accumulated other comprehensive income to retained earnings. These updates are effective in the first quarter of fiscal 2020, with early adoption permitted, and are not expected to materially impact the Company's financial statements. In the first quarter of fiscal 2018, the Company adopted updates to ASC 330, Inventory, which changed the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. These updates did not materially impact the Company's financial statements. In the first quarter of fiscal 2018, the Company adopted updates to ASC 740, Income Taxes, requiring recognition of the income tax effects of intra-entity transfers of assets other than inventory when the transfer occurs. These updates were adopted on a modified retrospective basis and did not materially impact the Company's financial statements.
