Income Taxes	12. Income Taxes Our tax provision is determined using an estimated annual effective tax rate and adjusted for discrete taxable events that may occur during the quarter. We recognize the effects of tax legislation in the period in which the law is enacted. Our deferred tax assets and liabilities are remeasured using enacted tax rates expected to apply to taxable income in the years we estimate the related temporary differences to reverse. On December 22, 2017, the President of the United States signed and enacted comprehensive tax legislation into law H.R. 1, commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). Except for certain provisions, the Tax Act was effective for tax years beginning on or after January 1, 2018. As a fiscal year U.S. taxpayer with an October 31 fiscal year end, the majority of the new provisions, such as eliminating the domestic manufacturing deduction, creating new taxes on certain foreign sourced income and introducing new limitations on certain business deductions, did not apply until our 2019 fiscal year. For fiscal 2018, the most significant impacts included: lowering of the U.S. federal corporate income tax rate; remeasuring certain net deferred tax assets and liabilities; and requiring the transition tax on the deemed repatriation of certain foreign earnings. In the first quarter of fiscal 2018, we recorded $1.7 million in one-time, non-cash charges related to the revaluation of our net deferred tax assets (approximately $1.4 million) and the transition tax on the deemed repatriation of foreign earnings (approximately $0.3 million).
