Fair value measurement

12 Months Ended

Sep. 30, 2022

The Company assesses the fair value of financial instruments based on the provisions of ASC 820, Fair Value Measurements. ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considering counterparty credit risk in its assessment of fair value.

Contractual maturities of short-term investments, as of September 30, 2022, were less than 12 months. The Company does not intend to sell the money market funds and short term investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis. The unrealized loss on short-term investments have been in a continuous unrealized loss position for less than 12 months.

As of September 30, 2022, the Company’s contingent consideration related to its Abveris acquisition is categorized as Level 3 within the fair value hierarchy. Contingent consideration is classified as a liability and is remeasured to an estimated fair value at each reporting date until the contingency is resolved. Contingent consideration has been recorded at

its fair values using unobservable inputs and have included using the Monte Carlo simulation option pricing framework, incorporating contractual terms and assumptions regarding financial forecasts, discount rates, and volatility of forecasted revenue. The key assumptions are forecasted calendar year 2022 revenue and the Company's share price. The development and determination of the unobservable inputs for Level 3 fair value measurements and fair value calculations are the responsibility of the Company’s management with the assistance of a third-party valuation specialist.

The key inputs into the Monte Carlo simulation as of December 1, 2021, the acquisition date and as of September 30, 2022 were as follows:


	September 30,			December 1,
Contingent consideration	2022			2021
Stock price	$	35.24		$	87.06
Equity volatility	93.7		%	81.3		%
Risk-free interest rate	3.9		%	0.4		%
Revenue volatility	30.2		%	21.9		%
