Fair Value, Liabilities Measured on Recurring Basis, Unobservable Input Reconciliation [Table Text Block]

Changes in the fair value of our contingent consideration liability were as follows:

(in millions)
Balance as of December 31, 2019	$	354
Contingent consideration net expense (benefit)	(108)
Contingent consideration payments	(38)
Balance as of June 30, 2020	$	208

Fair Value Measurement Inputs and Valuation Techniques [Table Text Block]

The recurring Level 3 fair value measurements of our contingent consideration liability that we expect to be required to settle include the following significant unobservable inputs:

Contingent Consideration Liability	Fair Value as of June 30, 2020	Valuation Technique	Unobservable Input	Range				Weighted Average (1)
R&D, Regulatory and Commercialization-based Milestones	$97 million	Discounted Cash Flow	Discount Rate	3	%	-	3%	3%
			Probability of Payment	90	%	-	90%	90%
			Projected Year of Payment	2027		-	2027	2027
Revenue-based Payments	$111 million	Discounted Cash Flow	Discount Rate	11	%	-	14%	13%
			Probability of Payment	100	%	-	100%	100%
			Projected Year of Payment	2020		-	2024	2022

(1) Unobservable inputs were weighted by the relative fair value of the contingent consideration liability. For projected year of payment, the amount represents the median of the inputs and is not a weighted average.

Investment [Table Text Block]

The aggregate carrying amount of our strategic investments was comprised of the following:

	As of
(in millions)	June 30, 2020		December 31, 2019
Equity method investments	$	262	$	264
Measurement alternative investments (1)	200		171
Publicly-held equity securities (2)	—		1
Notes receivable	4		23
	$	467	$	458

(1) Measurement alternative investments are privately-held equity securities without readily determinable fair values that are measured at cost minus impairment, if any, adjusted to fair value for any observable price changes in orderly transactions for the identical or a similar investment of the same issuer.

(2) Publicly-held equity securities are measured at fair value with changes in fair value recognized currently in Other, net on our accompanying unaudited condensed consolidated statements of operations.
