Income Taxes

3 Months Ended

Note 11. Income Taxes

The following table provides details of income taxes (in millions, except percentages):



	Three Months Ended March 31,
	2020			2019
Income before income taxes	$	28.3		$	44.5
Income tax provision	$	7.9		$	13.4
Effective tax rate	28.0		%	30.1		%

The Company’s effective tax rate differs from the federal statutory rate of 21% primarily due to the tax impact of state taxes, geographic mix of earnings including foreign-derived intangible income deductions and global intangible low-taxed income, research and development ("R&D") tax credits, tax audit settlements, nondeductible compensation, and transfer pricing adjustments.

The Company’s effective tax rate during the three months ended March 31, 2020 reflects a discrete charge for non-deductible stock compensation in the period.

The Company's effective tax rate during the three months ended March 31, 2019 reflected the inability to fully benefit the discrete charges in the period, the inclusion of the U.S. Base Erosion and Anti-Abuse Tax and the net impact of unrecognized tax benefits.

As of March 31, 2020, the total amount of gross unrecognized tax benefits was $147.6 million.

The Company engages in continuous discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. There is a greater than remote likelihood that the balance of the gross unrecognized tax benefits will decrease by a range of approximately $16.0 million to $37.0 million within the next twelve months due to the completion of tax review cycles in various tax jurisdictions and lapses of applicable statutes of limitations.
