The effective income tax rate for the year ended December 31, 2017 was significantly impacted by recording the effect of the Tax Cuts and Jobs Act (the “Tax Act”), enacted on December 22, 2017 by the U.S. government. The Tax Act makes broad and complex changes to the Internal Revenue Code of 1986, as amended, which has affected the Company’s year ended December 31, 2017, including, but not limited to, reducing the maximum U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018, and requiring a one-time repatriation tax on certain un-repatriated earnings of foreign subsidiaries at a rate of 15.5% tax on post-1986 foreign earnings held in cash and an 8% rate on all other post-1986 earnings that is payable over eight years beginning with 8% of the liability due with the filing of the year ended December 31, 2017 federal tax return that will be due in 2018. On December 22, 2017, the Securities and Exchange Commission staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740, Income Taxes. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate to be included in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provision of the tax laws that were in effect immediately before the enactment of the Tax Act. While the Company is able to make reasonable estimates of the impact of the reduction in the corporate income tax rate and the deemed repatriation transition tax, the final impact of the Tax Act may differ from these estimates, due to, among other things, changes in the Company’s interpretations and assumptions, additional guidance that may be issued by the Internal Revenue Service, and actions it may take. The Company is continuing to gather additional information to determine the final impact. Any adjustments recorded to the provisional amounts through the fourth quarter of 2018 will be included as an adjustment to income tax expense. As a result of the Tax Act, the Company recorded additional income tax expense of $20.7 million due to the repatriation tax on deemed repatriation of deferred foreign income and of $1.0 million due to a re-measurement of deferred tax assets and liabilities, in the three months ended December 31, 2017. The Deemed Repatriation Transition Tax (the “Repatriation Tax”) is a tax on previously untaxed accumulated earnings and profits (“E&P”) of certain of its foreign subsidiaries. To determine the amount of the Repatriation Tax, the Company must determine, in addition to other factors, the amount of post-1986 E&P of the relevant subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. The Company is able to make a reasonable estimate and recorded a provisional Repatriation Tax obligation of $20.7 million. Because of the complexity of the new Global Intangible Low-Taxed Income (“GILTI”) tax rules, the Company continues to evaluate this provision of the Tax Act and the application of ASC 740. Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred (the “period cost method”) or factoring such amounts into the Company’s measurement of its deferred taxes (the “deferred method”). The Company is currently in the process of analyzing its structure and, as a result, is not yet able to reasonably estimate the effect of this provision of the Tax Act. Therefore, the Company has not made any adjustments related to potential GILTI tax in its financial statements and has not made a policy decision regarding whether to record deferred tax on GILTI. As of December 31, 2017, the Company does not have a valuation allowance against its U.S. deferred tax assets. The Company analyzed all sources of available income and determined that they are more likely than not to realize the tax benefits of their deferred assets in future periods or carryback years. As of December 31, 2017, the Company has a valuation allowance against certain foreign deferred tax assets. The Company is recording a valuation allowance in foreign jurisdictions with an overall deferred tax loss. The valuation allowance will be reduced at such time as management believes it is more likely than not that the deferred tax assets will be realized. Any reductions in the valuation allowance will reduce future income tax provision. As of December 31, 2017, the Company has no U.S. federal net operating loss or credit carryforwards as any attributes are expected to be fully utilized to offset tax in the current year. At December 31, 2017, the Company has foreign net operating loss carryforwards of approximately $1.25 million in various jurisdictions with various expirations. As a result of capital return activities approved by the Board of Directors during the first quarter of 2016 and anticipated future capital return activities, the Company determined that a portion of its current undistributed foreign earnings are no longer deemed reinvested indefinitely by its non-U.S. subsidiaries. The Company repatriated $19.8 million to the U.S. during the three months ended March 31, 2016, part of which was offset by U.S. net operating losses. Accordingly, the deferred tax liability previously established for undistributed foreign earnings up to its existing U.S. net operating losses was reduced. The excess amount repatriated during the year ended December 31, 2017 was generated from current foreign earnings. The Company will continue to periodically reassess the needs of its foreign subsidiaries and update its indefinite reinvestment assertion as necessary. To the extent that additional foreign earnings are not deemed permanently reinvested, the Company expects to recognize additional income tax provision at the applicable U.S. corporate income tax rate. As of December 31, 2017, the Company has recorded a state deferred tax liability for earnings that the Company plans to repatriate out of accumulated earnings in future periods. Due to the Tax Act, repatriation from foreign subsidiaries will be offset with a dividends received deduction, resulting in little to no impact on federal tax expense. All undistributed earnings in excess of 50% of current earnings on an annual basis are intended to be reinvested indefinitely as of December 31, 2017. The Company and its subsidiaries file tax returns in the United States, California and Texas and various foreign jurisdictions. For federal income tax purposes, fiscal years 2007 through 2016 remain open for examination by tax authorities as a result of net operating loss carryovers from older years being used to offset income in recent tax years. The Company is no longer subject to state income tax examinations for years prior to 2011. No jurisdictions are currently examining any income tax returns of the Company or its subsidiaries except that the Taiwan Taxation Administration is currently examining the Taiwan subsidiary’s 2016 tax return. No adjustments have been proposed at this time.
