Note 13. Income Taxes

The following table summarizes the Company’s provision for income taxes and effective income tax provision rate for the three month periods ended March 31, 2019 and 2018.

	For the Three Month Period Ended March 31, 2019			For the Three Month Period Ended March 31, 2018
Income before income taxes	$	59.1		$	65.8
Provision for income taxes	$	12.0		$	23.4
Effective income tax provision rate		20.3	%		35.6	%

The decrease in the provision for income taxes and decrease in the effective income tax provision rate for the three month period ended March 31, 2019 when compared to the same three month period of 2018 was primarily due to an increase in the amount of earnings generated in countries with lower statutory tax rates, an increase in windfall tax benefits and the Transition tax imposed under the Tax Cuts and Jobs Act of 2017.
