⁽¹⁾	Taxes attributable to the controlling interest divided by Income before income taxes (controlling interest).

The Effective tax rate attributable to the controlling interest was 34.6% and 32.1% for the three months ended March 31, 2016 and 2017, respectively. The decrease resulted primarily from stock compensation-related windfall tax benefits, as well as an increase in the indefinite reinvestment of certain foreign earnings.
