[1] Short-term investments consist of money market funds (Level 1) and pooled bond funds (Level 2). Level 2 investments are priced using observable inputs, such as quoted prices in markets that are not active and yield curves.

[2] Contingent consideration liabilities are measured using the income approach and discounted to present value based on an assessment of the probability that the Company would be required to make such future payments. The contingent consideration liabilities are measured at fair value using significant Level 3 (unobservable) inputs, such as discount rates and probability measures. Remeasurement of the contingent consideration to fair value is expensed through the income statement in the period remeasured. Contingent consideration–current is included in accrued expenses and other current liabilities and contingent considerations–non-current is included in other liabilities on the balance sheet.
