Income Tax Disclosure [Abstract]

INCOME TAXES

INCOME TAXES

The following table summarizes our income tax expense:

						Three Months Ended
						March 31,
(in millions, except percentages)						2021						2020
Income before income taxes						$	2,264					$	2,003
Income tax expense						$	542					$	465
Effective tax rate						23.9		%				23.2		%

Our effective income tax rate of 23.9% for the three months ended March 31, 2021 differed from the U.S. federal statutory rate of 21% primarily due to unfavorable changes in the fair value of our equity investment in Galapagos that are non-deductible for income tax purposes, partially offset by net discrete tax benefits related to settlements with taxing authorities.

Our effective income tax rate of 23.2% for the three months ended March 31, 2020 differed from the U.S. federal statutory rate of 21% primarily due to the Global Intangible Low-Taxed Income tax, state taxes and our portion of the non-deductible branded prescription drug fee.

We are currently under examination by the U.S. Internal Revenue Service for the tax years from 2016 to 2018 and by various state and foreign jurisdictions. There are differing interpretations of tax laws and regulations, and as a result, significant disputes may arise with these tax authorities involving issues of the timing and amount of deductions and allocations of income among various tax jurisdictions. We regularly evaluate our exposures associated with our tax filing positions to determine our assessment of unrecognized tax benefits in accordance with the income tax guidance which clarifies the accounting for uncertainty in income taxes.
