Stock-Based Compensation

Stock-Based Compensation

We grant stock options for a fixed number of shares to certain employees with an exercise price equal to the fair value of the shares at the date of grant. We also grant restricted stock, restricted stock units and performance stock units with a fair value generally determined based on our closing stock price on the date of grant. In addition, we grant cash settled stock units (Darden stock units) which are classified as liabilities and are marked to market as of the end of each period.

The weighted-average fair value of non-qualified stock options and the related assumptions used in the Black-Scholes option pricing model for options granted during the periods presented, were as follows:

	Six Months Ended
	November 29, 2020			November 24, 2019
Weighted-average fair value	$	20.07		$	19.94
Dividend yield	3.0		%	3.0		%
Expected volatility of stock	37.3		%	22.5		%
Risk-free interest rate	0.4		%	1.9		%
Expected option life (in years)	6.4			6.3
Weighted-average exercise price per share	$	78.84		$	124.24

The weighted-average grant date fair value of performance-based restricted stock units and the related assumptions used in the Monte Carlo simulation to record stock-based compensation for units granted during the periods presented, were as follows:

	Six Months Ended

Dividend yield (1)	0.0		%	0.0		%
Expected volatility of stock	50.5		%	23.1		%
