ASC 820, “Fair Value Measurement,” establishes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the third is considered unobservable:

Level 1: Quoted prices for identical assets or liabilities in active markets which the Company can access

The Company’s cash equivalents are highly liquid investments with original maturities of three months or less, which represent an asset the Company measures at fair value on a recurring basis. The Company determines the fair value of cash equivalents using a market approach based on quoted prices in active markets. The fair values of cash equivalents, accounts

receivable, income taxes receivable, accounts payable, income taxes payable and accrued expenses and other current liabilities approximate their carrying values because of their short-term nature.

The Company addresses market risks from changes in foreign currency exchange rates through a risk management program that includes the use of derivative financial instruments to mitigate certain balance sheet foreign currency transaction exposures. The Company uses foreign currency forward contracts as a part of its strategy to manage exposures related to foreign currency denominated monetary assets and liabilities.

On August 30, 2021, the Company acquired ATI. Under the purchase and sale agreement for the ATI acquisition, the former shareholders of ATI (the “Sellers”) are eligible to receive contingent consideration based on ATI’s fiscal year 2021 Adjusted EBITDA, as defined in the purchase and sale agreement. The contingent consideration would be payable in 2022 after the Sellers and the Company agree on the final amount for the Adjusted EBITDA. The estimated fair value of the contingent consideration was determined based on the Monte Carlo valuation method and was recorded as part of the purchase price as of the acquisition date. Subsequent changes in the estimated fair value were recorded in the consolidated statement of operations in restructuring, acquisition, and related costs until the liability was fully settled. The fair value of the contingent consideration was $44.0 million as of December 31, 2021. During 2022, the fair value of the contingent consideration was adjusted to $45.0 million based on the final determination of ATI’s 2021 Adjusted EBITDA. The Company made the contingent consideration payment of $45.0 million in August 2022. The estimated fair value of $44.0 million included in the determination of the purchase price is reported as a cash outflow from financing activities in the consolidated statement of cash flows for 2022 while the remaining $1.0 million payment is reported as a cash outflow from operating activities.

On July 31, 2019, the Company acquired ARGES GmbH (“ARGES”). Under the purchase and sale agreement for the ARGES acquisition, the former owner of ARGES is eligible to receive contingent consideration based on the achievement of certain revenue targets by the Company from August 2019 through December 2026. The undiscounted range of possible contingent consideration is zero to €10.0 million ($11.1 million). If the revenue targets are achieved, the contingent consideration would be payable annually with the first payment due in the first quarter of 2021. The estimated fair value of the contingent consideration of €7.1 million ($7.9 million) was determined based on the Monte Carlo valuation method and was recorded as part of the purchase price as of the acquisition date. Subsequent changes in the estimated fair value of the contingent consideration liability are recorded in the consolidated statement of operations in restructuring, acquisition, and related costs until the liability is fully settled. During 2020, the fair value of the contingent consideration was adjusted to €4.1 million ($5.1 million). The Company made the first installment payment of €0.4 million ($0.4 million) in March 2021 and adjusted the fair value of the contingent consideration to €3.3 million ($3.8 million) as of December 31, 2021. The Company made the second installment payment of €0.3 million ($0.4 million) in March 2022. Based on the revenue performance and revenue projections as of December 31, 2022, the fair value of the remaining contingent consideration was adjusted to €0.4 million ($0.4 million). The installment payments have been reported as cash outflows from financing activities in the consolidated statement of cash flows for the respective periods.

On April 16, 2019, the Company acquired Ingenia CAT, S.L. (“Ingenia”). Under the purchase and sale agreement for the Ingenia acquisition, the shareholders of Ingenia are eligible to receive contingent consideration based on the achievement of certain revenue targets by the Company from April 2019 through March 2022. The undiscounted range of possible contingent consideration is zero to €8.0 million ($9.0 million). If the revenue targets are achieved, the contingent consideration would be payable in cash in three annual installments from 2020 to 2022. The estimated fair value of the contingent consideration of €5.8 million ($6.6 million) was determined based on the Monte Carlo valuation method and was recorded as part of the purchase price as of the acquisition date. Subsequent changes in the estimated fair value of the contingent consideration liability were recorded in the consolidated statement of operations in restructuring, acquisition, and related costs until the liability was fully settled. The Company made the first installment payment of €1.0 million ($1.1 million) in May 2020 and adjusted the fair value of the contingent consideration to €2.3 million ($2.9 million) as of December 31,2020. The Company made the second installment payment of €1.2 million ($1.4 million) in May 2021 and adjusted the fair value of the contingent consideration to €1.5 million ($1.7 million) as of December 31, 2021. During the three months ended July 1, 2022, the fair value of the remaining contingent consideration was adjusted to €1.8 million ($1.9 million). The Company made the final installment payment of €1.8 million ($1.9 million) in July 2022. The installment payments have been reported as cash outflows from financing activities in the consolidated statement of cash flows for the respective periods.

On December 14, 2016, the Company acquired certain video signal processing and management technologies used in medical visualization solutions. Under the purchase and sale agreement, the former owners are eligible to receive contingent consideration based on the achievement of certain revenue targets by the Company from 2018 to 2021 from products utilizing the acquired technologies. The undiscounted range of possible contingent consideration is zero to €5.5 million ($6.6 million). If the revenue targets are achieved, the contingent consideration would be payable in cash in four installments from 2019 to 2022. As the acquired assets did not meet the definition of a business, the fair value of the contingent consideration is recognized when probable and estimable and is capitalized as part of the cost of the acquired assets. Subsequent changes in the estimated fair value of this contingent liability have been recorded as adjustments to the carrying value of the assets acquired and are amortized over the remaining useful life of the underlying assets. Based on revenue achievements against the target through the end of 2021, the Company recognized an aggregate fair value of €5.5 million ($6.3 million) for the acquired intangible assets. The Company made the first installment payment of €2.4 million ($2.6 million) in February 2020, the second installment payment of €1.8 million ($2.2 million) in February 2021, and the final installment payment of €1.3 million ($1.5 million) in March 2022. The installment payments have been reported as cash outflows from investing activities in the consolidated statement of cash flows for the respective periods.
