Fair Value of Derivative Financial Instruments:

The Company’s derivative financial instruments consist of foreign currency forward contracts and interest rate swaps. Fair values for derivative financial instruments are based on independent sources including highly rated financial institutions and are classified as Level 2. Refer to Note 17 - Derivatives and Hedge Accounting to the unaudited consolidated financial statements for further details.

Fair Value of Contingent Consideration:

The fair value measurement of contingent consideration is determined using Level 3 inputs. The Company’s contingent consideration represents a component of the total purchase consideration for business acquisitions. The measurement is calculated using unobservable inputs based on the Company’s own assessment of achievement of certain performance goals. The Company estimated the fair value of the contingent consideration based on the Monte Carlo simulation model and scenario-based method.

The following table summarizes the changes in the fair value of contingent consideration:


	Three months ended June 30,				Six months ended June 30,
	2024		2023		2024		2023
Opening balance	$	—	$	18,689	$	15,589	$	18,689

Payments	—		(5,000)		(15,000)		(5,000)
Closing balance	$	—	$	13,689	$	—	$	13,689

During the three and six months ended June 30, 2024 and 2023, there were no transfers among Level 1, Level 2 and Level 3.

Financial Instruments Not Carried at Fair Value:

The Company’s other financial instruments not carried at fair value consist primarily of cash and cash equivalents (except investments in money market funds, as disclosed above), short-term investments (except investments in mutual funds, as disclosed above), restricted cash, accounts receivable, net, long-term investments, accrued capital expenditures, accrued expenses, client liabilities and interest payable on borrowings for which fair values approximate their carrying amounts. The carrying value of the Company’s outstanding revolving credit facility approximates its fair value because the Company’s interest rate yield is near current market rates for comparable debt instruments.
