The Company’s Amended and Restated 2003 Plan provides for the granting of stock options, stock appreciation rights (SARs), dividend equivalent rights, restricted stocks, restricted stock units, performance units and performance shares, the vesting of which may be time-based or upon satisfaction of performance criteria or other conditions.

As of June 29, 2024, the Company had 9.1 million shares subject to Full Value Awards (defined below) issued and outstanding and 13.1 million shares of common stock available for grant under the Amended and Restated 2003 Plan.

The Company’s ESPP provides eligible employees with the opportunity to acquire an ownership interest in the Company through periodic payroll deductions and provides a discounted purchase price as well as a look-back period. The ESPP is structured as a qualified employee stock purchase plan under Section 423 of the Internal Revenue Code of 1986. As of June 29, 2024, 6.8 million shares remained available for issuance. The ESPP as amended provides for a 15% discount with a look-back period of six months.

The Company's stock-based compensation includes a combination of time-based RSUs and performance- based MSUs and PSUs. RSUs are granted without an exercise price and are converted to shares immediately upon vesting. When converted into shares upon vesting, shares equivalent in value to the minimum withholding taxes liability on the vested shares are withheld by the Company for the payment of such taxes. For performance-based awards, shares attained over target upon vesting are reflected as awards granted during the period.

Time-based RSU awards will generally vest in annual installments over a period of three to four years subject to the employees’ continuing service to the Company. The Company's performance-based MSU and PSU awards may include performance conditions, market conditions, time-based service conditions or a combination thereof and are generally expected to vest over one to four years. In addition, the actual number of shares awarded upon vesting of performance-based grants may vary from the target shares depending upon the achievement of the relevant performance or market-based conditions.

(1) Performance Shares refer to the Company’s MSU and PSU awards, where the actual number of shares awarded upon vesting may be higher or lower than the target amount depending on the achievement of the relevant market conditions and performance goal achievement. The majority of MSUs vest in equal annual installments over three to four years based on the attainment of certain total shareholder performance measures and the employee’s continued service through the vest date. The aggregate grant-date fair value of MSUs granted during fiscal 2024, 2023 and 2022 was estimated to be $13.4 million, $11.4 million and $7.9 million, respectively, and was calculated using a Monte Carlo simulation. The Company did not grant any PSU awards in fiscal 2024, 2023 and 2022. PSU awards vest based on the attainment of certain performance measures and the employee’s continued service through the vest date.

As of June 29, 2024, $54.9 million of unrecognized stock-based compensation cost related to Full Value Awards remains to be amortized. That cost is expected to be recognized over the remaining amortization period of 1.5 years.

The Company estimates the fair value of time-based RSU awards based on the closing market price of the Company’s common stock on the date of grant. In the case of PSUs that are performance-based awards without a market condition, the Company will estimate the fair value of the awards using a probability weighted model. In the case of MSUs or PSUs, that are performance-based awards and include a market condition, the Company will estimate the fair value of the awards using a combination of the closing market price of the Company’s common stock on the grant date and the Monte Carlo simulation model.The weighted-average assumptions used to measure fair value of performance-based awards with a market condition were as follows:






	Years Ended
	June 29, 2024		July 1, 2023		July 2, 2022
Volatility of common stock	34.8	%	31.2	%	33.8	%
Average volatility of peer companies	65.8	%	62.1	%	58.7	%
Average correlation coefficient of peer companies	0.2305		0.3111		0.3442
Risk-free interest rate	4.9	%	3.4	%	0.2	%

The Company did not issue stock option grants during the fiscal years ended June 29, 2024, July 1, 2023 and July 2, 2022. The Company estimates the fair value ESPP purchase rights using a BSM valuation model. The fair value is estimated on the date of grant using the BSM option valuation model with the following weighted-average assumptions:


	Employee Stock Purchase Plans
	June 29, 2024		July 1, 2023		July 2, 2022
Expected term (in years)	0.5		0.5		0.5
Expected volatility	29.8	%	37.2	%	24.3	%
Risk-free interest rate	5.3	%	3.8	%	0.3	%

Risk-Free Interest Rate: The Company bases the risk-free interest rate used in the BSM valuation method on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term.

Expected Dividend: The BSM valuation model calls for a single expected dividend yield as an input. The Company has not paid and does not anticipate paying any dividends in the near future.
