Derivative financial instruments are classified within level 2 because there is not an active market for each derivative contract. However, the inputs used to calculate the value of the instruments are obtained from active markets.

The Company measures certain assets and liabilities at fair value with changes in fair value recognized in earnings. Fair value treatment may be elected either upon initial recognition of an eligible asset or liability or, for an existing asset or liability, if an event triggers a new basis of accounting. The Company did not elect to remeasure any of its existing financial assets or liabilities and did not elect the fair value option for any financial assets or liabilities which originated during the year ended December 31, 2021 or 2020.

The fair value of the long-term fixed interest rate debt, which has been classified as Level 2, was based on market and observable sources with similar maturity dates. The remaining long-term debt has variable interest rates and the carrying value approximates fair value accordingly.

On a quarterly basis, the Company reviews its short-term investments to determine if there have been any events that could create an impairment. None were noted for the years ended December 31, 2021, 2020 and 2019.

Debt securities consist of investments in redeemable preferred stock. Debt securities are classified as either current or long-term investments based on their contractual maturities unless the Company intends to sell an investment within the next twelve months, in which case it is classified as current on the consolidated balance sheets. Debt securities are classified as available for sale and are carried at fair value.

Contingent consideration recorded within other liabilities represents the estimated fair value of future payments to the former shareholders as part of certain acquisitions. These contingent consideration amounts are primarily based on the applicable acquired company achieving annual revenue and gross margin targets in certain years as specified in the relevant purchase and sale agreement. The Company initially values the contingent consideration on acquisition date by using a Monte Carlo simulation or an income approach method. The Monte Carlo method models future revenue and costs of goods sold projections and discounts the average results to present value. The income approach method involves calculating the earnout payment based on the forecasted cash flows, adjusting the future earnout payment for the risk of reaching the projected financials, and then discounting the future payments to present value by the counterparty risk. The counterparty risk considers the risk of the buyer having the cash to make the earnout payments and is commensurate with a cost of debt over an appropriate term.

The following table sets forth the changes in contingent consideration liabilities (in millions):


Balance at December 31, 2019	$	15.8
Current period additions		1.2
Current period adjustments		(4.4	)
Current period settlements		(8.7	)
Foreign currency effect		0.4

Balance at December 31, 2020		4.3
Current period additions		2.6
Current period adjustments		0.2

As part of the Mestrelab acquisition, the Company entered into an agreement with the noncontrolling interest holders that provides the Company with the right to purchase, and the noncontrolling interest holders with the right to sell, the remaining 49% of Mestrelab for cash at a contractually defined redemption value. These

rights (an embedded derivative) are exercisable beginning in 2022 and can be accelerated, at a discounted redemption value, upon certain events related to post combination services. As the option is tied to continued employment, the Company classified the hybrid instrument (noncontrolling interest with an embedded derivative) within short-term and long-term liabilities on the consolidated balance sheet. Subsequent to the acquisition, the carrying value of the hybrid instrument is remeasured to fair value with changes recorded to stock-based compensation expense in proportion to the requisite service period vested. The hybrid instrument is classified as Level 3 in the fair value hierarchy.

The following table sets forth the changes in hybrid instrument liability (in millions):


Balance at December 31, 2019	$	10.6
Current period additions		2.6
Foreign currency effect		0.7

Balance at December 31, 2020		13.9
Current period additions		2.7
Foreign currency effect		(1.0	)

Balance at December 31, 2021	$	15.6
