Our provision for income taxes for the three months ended March 31, 2018 was $7.3 million. Our provision for income taxes was adjusted for an income tax benefit of $4.9 million, net, for discrete items primarily related to changes in estimates in uncertain tax positions, an adjustment for stock based compensation in accordance with ASU 2016-09, and changes in the valuation allowance in various jurisdictions. Without the $4.9 million in discrete items, the effective income tax rate would have been 31.7% for the three months ended March 31, 2018. Our provision for income taxes for the three months ended March 31, 2017 was $5.0 million and was adjusted for an income tax benefit of $1.2 million, net, for discrete items related to changes in estimates in uncertain tax positions and an adjustment for stock based compensation. Without the $1.2 million in discrete items, the three months ended March 31, 2017 effective income tax rate would have been 10.6%. Our provision for income taxes for each of the three months ended March 31, 2018 and 2017 was calculated based on the estimated annual effective income tax rate for 2018 and 2017 fiscal years. The actual effective income tax rate for the 2018 fiscal year may be materially different as a result of differences between estimated versus actual results and the geographic tax jurisdictions in which the results are earned. We operate under a special income tax concession in Singapore which began January 1, 2008. Our current 5 year special income tax concession was effective January 1, 2018. The special income tax concession is conditional upon our meeting of certain employment and investment thresholds which, if not met in accordance with our agreement, may eliminate the benefit beginning with the first year in which the conditions are not satisfied. The income tax concession reduces the income tax rate on qualified sales and the impact of this income tax concession increased foreign income taxes by $0.1 million and decreased foreign income taxes by $0.8 million for the three months ended March 31, 2018 and 2017, respectively. The income tax concession had no impact on basic earnings per common share for the three months ended March 31, 2018 and an impact of $0.01 on basic earnings per common share for the three months ended March 31, 2017. The income tax concession had no impact on diluted earnings per common share for the three months ended March 31, 2018 and an impact of $0.01 on diluted earnings per common share for the three months ended March 31, 2017. We have various income tax returns under examination both in the U.S. and in foreign jurisdictions. The most significant of these are in Korea for the 2011 to 2014 tax years, in Denmark for the 2013 to 2015 tax years and the U.S. for the 2013 to 2016 tax years. In 2017, the South Korea branch of one of our subsidiaries received income tax assessment notices for the years 2011 to 2014 totaling $10.6 million (KRW 11.3 billion). We believe that these assessments are without merit and are currently appealing the actions. During the quarter ended March 31, 2018, one of our Denmark subsidiaries received an audit inquiry from the Denmark tax authorities relating to transfer pricing and related issues for the tax years 2013 to 2015. In addition, in 2017, we received a notice of examination from the U.S. Internal Revenue Service for the 2013 to 2016 tax years. We are currently responding to the requests from the U.S. and Denmark tax authorities. An unfavorable resolution of one or more of the above matters could have a material adverse effect on our results of operations or cash flows in the quarter and year in which an adjustment is recorded or the tax is due or paid. As audits and examinations are still in process or we have not yet reached the final stages of the appeals process, the timing of the ultimate resolution and any payments that may be required for the above matters cannot be determined at this time.
