Note 13: Income Taxes

The Company has historically determined its interim income tax provision by applying the estimated effective income tax rate expected to be applicable for the full fiscal year to the income before income taxes for the period. In determining the full year estimate, the Company does not include the estimated impact of unusual and/or infrequent items, which may cause significant variations in the customary relationship between income tax expense and income before income taxes. Significant judgment is exercised in determining the income tax provision due to transactions, credits and calculations where the ultimate tax determination is uncertain.

The Company’s effective tax rate for the quarter ended March 30, 2018 was 10.5%, which differs from the U.S. federal income tax rate of 21% principally due to discrete benefits of $17.1 million relating to an increase in deferred tax assets expected to be realized in the foreseeable future due to the liquidation of a foreign subsidiary and $6.7 million relating to equity award excess tax benefits. These benefits are partially offset by foreign taxes for which the Company will not receive a U.S. tax credit as a result of U.S. tax reform and the Company's U.S. federal net operating loss carryforwards.

In December 2017 the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which allows the Company to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. As of March 30, 2018, the Company has not completed its accounting for the tax effects of the enactment of the Tax Act; however, in certain cases, specifically as follows, the Company made a reasonable estimate of (i) the effects on its existing deferred tax balances and (ii) the effects of the one-time mandatory repatriation tax. The Company recognized a provisional tax benefit of $449.9 million in the year ended December 31, 2017 associated with the items it could reasonably estimate. For the quarter ended March 30, 2018, there have not been any adjustments made to these estimates. The Company is still analyzing the Tax Act and refining its calculations, which could potentially impact the measurement of its tax balances. The Company expects to complete its analysis within the measurement period in accordance with SAB 118.

At March 30, 2018, the Company was not able to reasonably estimate, and therefore has not recorded, deferred taxes for the Global Intangible Low-Taxed Income (“GILTI”) provisions of the Tax Act. The Company has not yet determined its policy election with respect to whether to record deferred taxes for basis differences expected to reverse as a result of the GILTI provisions in future periods or use the period cost method. The Company has, however, included an estimate of the current impact of GILTI in its tax provision for 2018.

The Company recognizes interest and penalties related to unrecognized tax benefits in tax expense on the Company's Consolidated Statements of Operations and Comprehensive Income. The Company had approximately $6.4 million and $5.4 million of net interest and penalties accrued at March 30, 2018 and March 31, 2017, respectively.

Although the Company cannot predict the timing of resolution with taxing authorities, if any, it believes it is reasonably possible that $13.4 million of its unrecognized tax benefits will be reduced in the next 12 months due to settlement with tax authorities or expiration of the applicable statute of limitations.

Tax years 2013 and prior are generally not subject to examination by the Internal Revenue Services (the “IRS”) except for items involving tax attributes that have been carried forward to tax years whose statute of limitations remains open. The Company is not currently under IRS examination. For state tax returns, the Company is generally not subject to income tax examinations for years 2012 and prior. The Company is also subject to routine examinations by various foreign tax jurisdictions in which it operates. With respect to major jurisdictions outside the United States, the Company's subsidiaries are no longer subject to income tax audits for years prior to 2007. The Company is currently under audit in the following significant jurisdictions: China, Malaysia, Mauritius, Singapore and Vietnam.
