INCOME TAX

Our effective income tax rates for the three months ended March 31, 2020 and 2019 were 10.1% and 16.8%, respectively. Our effective income tax rate for the three months ended March 31, 2020 differed from the U.S. statutory rate primarily as a result of tax credits, excess tax benefits of share-based awards that are recognized upon vesting or settlement and the foreign-derived intangible income deduction. For the three months ended March 31, 2019, our effective income tax rate differed from the U.S. statutory rate primarily due to the excess tax benefits of share-based awards that are recognized upon vesting or settlement.

We conduct business globally and file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business, we are subject to examination by taxing authorities around the world, including, without limitation, the United States and the United Kingdom. We are no longer subject to state income tax examinations for years ended on or before May 31, 2010, U.S. federal income tax examinations for years ended on or before December 31, 2016 and U.K. federal income tax examinations for years ended on or before May 31, 2016.
