Royalty Pharma Contingent Milestone Receipts

During the year ended December 31, 2020, Royalty Pharma payments from Biogen for Tysabri® sales, as defined in the agreement between the parties, did not exceed the 2020 global net sales threshold. Therefore, we were not entitled to receive the remaining contingent milestone payment. As of December 31, 2020, there were no contingent milestone payments outstanding.

The table below summarizes the change in fair value of the Royalty Pharma contingent milestone (in millions):


	Three Months Ended

Beginning balance	$	95.3



Change in fair value	1.6
Ending balance	$	96.9

We valued our contingent milestone payment from Royalty Pharma using a modified Black-Scholes Option Pricing Model ("BSOPM"). Key inputs in the BSOPM are the estimated volatility and rate of return of royalties on global net sales of Tysabri® that are received by Royalty Pharma until the contingent milestones are resolved. As of March 28, 2020, volatility and the estimated fair value of the milestones had a positive relationship such that higher volatility translates to a higher estimated fair value of the contingent milestone payments. Rate of return and the estimated fair value of the milestones had an inverse relationship, such that a lower rate of return correlates with a higher estimated fair value of the contingent milestone payments. We assessed volatility and rate of return inputs quarterly by analyzing certain market volatility benchmarks and the risk associated with Royalty Pharma achieving the underlying projected royalties. The table below represents the volatility and rate of return:


	Three Months Ended
	March 28, 2020
Volatility	35.0	%
Rate of return	7.29	%

During the three months ended March 28, 2020, the fair value of the Royalty Pharma contingent milestone payment related to 2020 increased by $1.6 million to $96.9 million, driven by higher volatility, higher projected global net sales of Tysabri® compared to the estimates in the prior period, and the estimated probability of achieving the earn-out. As of December 31, 2020, there were no contingent milestone payments outstanding and, accordingly, no asset recorded in the Condensed Consolidated Balance Sheet.

Non-recurring Fair Value Measurements

The non-recurring fair values represent only those assets whose carrying values were adjusted to fair value during the reporting period.

Fixed Rate Long-term Debt

Our fixed rate long-term debt consisted of the following (in millions):


	April 3, 2021				December 31, 2020
	Level 1		Level 2		Level 1		Level 2
Public Bonds
Carrying Value (excluding discount)	$	2,760.0	$	—	$	2,760.0	$	—
Fair value	$	2,863.7	$	—	$	3,031.1	$	—

Private placement note
Carrying value (excluding premium)	$	—	$	158.8	$	—	$	164.9
Fair value	$	—	$	176.6	$	—	$	177.5

The fair values of our public bonds for all periods were based on quoted market prices. The fair values of our private placement note for all periods were based on interest rates offered for borrowings of a similar nature and remaining maturities.

The carrying amounts of our other financial instruments, consisting of cash and cash equivalents, accounts receivable, accounts payable, short-term debt, revolving credit agreements, promissory notes related to our equity method investment in Kazmira, and variable rate long-term debt, approximate their fair value.
