15. FAIR VALUE MEASUREMENTS

 
Fair value is considered the price to sell an asset, or transfer a liability, between market participants on the measurement date. Fair value measurements assume that (1) the asset or liability is exchanged in an orderly manner, (2) the exchange is in the principal market for that asset or liability, and (3) the market participants are independent, knowledgeable, able and willing to transact an
exchange. Fair value accounting and reporting establishes a framework for measuring fair value by creating a hierarchy for observable independent market inputs and unobservable market assumptions and expands disclosures about fair value measurements. Judgment is required to interpret the market data used to develop fair value estimates. As such, the estimates presented herein are not necessarily indicative of the amounts that could be realized in a current exchange. The use of different market assumptions and/or estimation methods could have a material effect on the estimated fair value.

Financial assets and liabilities measured at fair value on a recurring basis as of September 30, 2021 and 2020, are summarized in the following tables by the type of inputs applicable to the fair value measurements:

In fiscal year 2021, we entered into a contingent consideration arrangement related to the acquisition of Bayonet. At September 30, 2021, we estimated the fair value of this contingent consideration liability at $4,181. The table below presents the fair value of this obligation, which used significant unobservable inputs (Level 3).

In fiscal years 2016, 2017, and 2018, we entered into contingent consideration arrangements related to certain acquisitions. Please see Note 19, “Business Combinations” for further discussion. At September 30, 2021, we estimated the fair value of these contingent consideration liabilities at zero. The table below presents a reconciliation of the fair value of these obligations, which used significant unobservable inputs (Level 3).

Below is a description of the inputs used to value the assets summarized in the preceding tables:

Level 1 — Inputs represent unadjusted quoted prices for identical assets exchanged in active markets.

Level 2 — Inputs include directly or indirectly observable inputs other than Level 1 inputs such as quoted prices for similar assets exchanged in active or inactive markets; quoted prices for identical assets exchanged in inactive markets; and other inputs that are considered in fair value determinations of the assets.
Level 3 — Inputs include unobservable inputs used in the measurement of assets. Management is required to use its own assumptions regarding unobservable inputs because there is little, if any, market activity in the assets or related observable inputs that can be corroborated at the measurement date.
