Note 11 - Income taxes

On December 22, 2017, the U.S. President signed the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act, among other things, lowered the U.S. corporate income tax rate from 35% to 21% effective January 1, 2018. 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 allowed us to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. As a result, we previously recorded a provisional estimate of the effect of the Tax Act in our financial statements. In the first quarter of 2019, we completed our analysis to determine the effect of the Tax Act and recorded no additional adjustments as of December 22, 2018.

The Company uses an estimated annual effective tax rate, which is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates, to determine its quarterly provision (benefit) for income taxes.
