Fair Value Measurements, Nonrecurring

Valuation of RTSR Performance Shares and Performance Share Units

The fair value of each RTSR performance share unit is determined using the Monte Carlo pricing model because the number of shares to be awarded is subject to a market condition. The Monte Carlo simulation is a generally accepted statistical technique used to simulate a range of possible future outcomes. Because the valuation model considers a range of possible outcomes, compensation cost is recognized regardless of whether the market condition is actually satisfied.

The assumptions used in estimating the fair value of the RTSR performance share units granted during each year were as follows:

	Fiscal Year Ended June 30,
	2023				2022
Expected volatility	41	%	-	47%	39	%	-	41%
Expected life (in years)	2.4		-	2.9	2.4		-	2.9
Risk-free interest rates	3.0	%	-	4.6%	0.3	%	-	1.5%
Dividend yield	None				None
