Income Tax Provision

The following table shows our income tax provision and effective tax rate:


	Three Months Ended March 31,								Percentage Change
	2020			2019
	(in millions)
Income tax provision	$	70		$	66		6.1	%
Effective tax rate	25.6		%	21.1		%

The higher effective tax rate in the first quarter of 2020 is primarily due to a tax benefit recorded in 2019 from a dividends received deduction related to capital distributions from the OCC and the reversal of a previously accrued tax penalty in Finland.

The effective tax rate may vary from period to period depending on, among other factors, the geographic and business mix of earnings and losses. These same and other factors, including history of pre-tax earnings and losses, are taken into account in assessing the ability to realize deferred tax assets.

Tax Audits

Nasdaq and its eligible subsidiaries file a consolidated U.S. federal income tax return and applicable state and local income tax returns and non-U.S. income tax returns. We are subject to examination by federal, state and local, and foreign tax authorities. Federal income tax returns for the years 2008

through 2016 are currently under examination by the Internal Revenue Service and we are subject to examination by the Internal Revenue Service for 2017 and 2018. Several state tax returns are currently under examination by the respective tax authorities for the years 2007 through 2018. Non-U.S. tax returns are subject to examination by the respective tax authorities for the years 2013 through 2018. We regularly assess the likelihood of additional assessments by each jurisdiction and have established tax reserves that we believe are adequate in relation to the potential for additional assessments. Examination outcomes and the timing of examination settlements are subject to uncertainty. Although the results of such examinations may have an impact on our unrecognized tax benefits, we do not anticipate that such impact will be material to our consolidated financial position or results of operations. We do not expect to settle any material tax audits in the next twelve months.

We believe that the resolution of tax matters will not have a material effect on our financial condition but may be material to our operating results for a particular period and the effective tax rate for that period.
