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, 2021	Valuation Technique	Unobservable Input	Range				Weighted Average(1)
R&D, Regulatory and Commercialization-based Milestones	$22 million	Discounted Cash Flow	Discount Rate	2%				2%
			Probability of Payment	20%				20%
			Projected Year of Payment	2027				2027
Revenue-based Payments	$290 million	Discounted Cash Flow	Discount Rate	4	%	-	14%	6%
			Probability of Payment	80	%	-	100%	100%
			Projected Year of Payment	2021		-	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
