•2005 Equity Incentive Plan. Key employees and non-employee directors may be granted equity awards, including stock options, restricted stock and restricted stock units ("RSUs"). Options vest at 25% on each anniversary of the grant date and expire no later than eight years from the grant date. RSUs granted to date vest at 25% on each anniversary of the grant date.

•2015 Equity Incentive Plan ("2015 EIP"). Key employees and non-employee directors may be granted equity awards, including stock options, performance share units ("PSUs") and RSUs. Shares issued with respect to awards granted under the 2015 EIP other than stock options or stock appreciation rights, which are referred to as "full value awards", are counted against the 2015 EIP's aggregate share limit as three shares for every share or unit actually issued. No awards have been made under the 2015 Equity Incentive Plan since the adoption of the 2018 Equity Incentive Plan on March 8, 2018 described below.

•2018 Equity Incentive Plan ("2018 EIP"). Key employees and non-employee directors may be granted equity awards, including stock options, PSUs and RSUs. Shares issued with respect to awards granted under the 2018 EIP other than stock options or stock appreciation rights, which are referred to as "full value awards", are counted against the 2018 EIP's aggregate share limit as one share for every share or unit issued. At October 2, 2022, there were 2.2 million shares available for future awards pursuant to the 2018 EIP.

•Employee Stock Purchase Plan ("ESPP"). Purchase rights to purchase common stock are granted to our eligible full and part-time employees, and shares of common stock are issued upon exercise of the purchase rights. An aggregate of 380,784 shares may be issued pursuant to such exercise. The maximum amount that an employee can contribute during a purchase right period is $5,000. The exercise price of a purchase right is the lesser of 100% of the fair market value of a share of common stock on the first day of the purchase right period (the business day preceding January 1) or 85% of the fair market value on the last day of the purchase right period (December 15, or the business day preceding December 15 if December 15 is not a business day).

We recognize the fair value of our stock-based awards as compensation expense on a straight-line basis over the requisite service period in which the award vests. Most of these amounts were included in selling, general and administrative expenses on our consolidated statements of income.

The aggregate intrinsic value in the table above represents the total intrinsic value (the difference between our closing stock price on the last trading day of fiscal 2022 and the exercise price, times the number of shares) that would have been received by the in-the-money option holders if they had exercised their options on October 2, 2022. This amount will change based on the fair market value of our stock.

No stock options were granted in fiscal 2022, 2021 and 2020. The aggregate intrinsic value of options exercised during fiscal 2022, 2021 and 2020 was $5.7 million, $29.4 million and $22.4 million, respectively.

Net cash proceeds from the exercise of stock options were $1.8 million, $11.3 million and $10.3 million for fiscal 2022, 2021 and 2020, respectively. Our policy is to issue shares from our authorized shares upon the exercise of stock options. The actual income tax benefit realized from exercises of nonqualified stock options for fiscal 2022, 2021 and 2020 was $1.3 million, $6.7 million and $4.9 million, respectively.

RSU awards are granted to our key employee and non-employee directors. The fair value of the RSU was determined at the date of grant using the market price of the underlying common stock as of the date of grant. All of the RSUs have time-based vesting over a four-year period, except that RSUs awarded to directors vest after one year. The total compensation cost of the awards is then amortized over their applicable vesting period on a straight-line basis.

PSU awards are granted to our executive officers and non-employee directors. All of the PSUs are performance-based and vest, if at all, after the conclusion of the three-year performance period. The number of PSUs that ultimately vest is based 50% on growth in our EPS and 50% on our relative total shareholder return over the vesting period. For these performance-based awards, our expected performance is reviewed to estimate the percentage of shares that will vest. The total compensation cost of the awards is then amortized over their applicable vesting period on a straight-line basis.

(1) Fiscal 2020 includes a payout adjustment of 63,643 PSUs due to the actual performance level achieved for PSUs granted in fiscal 2017 that vested during fiscal 2020. Fiscal 2021 includes a payout adjustment of 99,214 PSUs due to the actual performance level achieved for PSUs granted in fiscal 2018 that vested during fiscal 2021. Fiscal 2022 includes a payout adjustment of 88,198 PSUs due to the actual performance level achieved for PSUs granted in fiscal 2019 that vested during fiscal 2022.

During fiscal 2022, 2021 and 2020, we awarded 77,844, 117,934 and 167,525 shares of RSUs, respectively, to our key employees and non-employee directors. The weighted-average grant-date fair value of RSUs granted during fiscal 2022, 2021 and 2020 was $184.61, $122.02 and $83.92, respectively. At October 2, 2022, there were 299,055 RSUs outstanding. RSU forfeitures result from employment terminations prior to vesting. Forfeited shares return to the pool of authorized shares available for award. We use historical data as a basis to estimate the probability of forfeitures related to RSUs and the ESPP Plan.

During fiscal 2022, 2021 and 2020, we awarded 41,734, 57,542 and 74,011 shares of PSUs, respectively, to our executive officers and non-employee directors. The weighted-average grant-date fair value of PSUs granted during fiscal 2022, 2021 and 2020 was $247.16, $153.03 and $99.85, respectively.

The stock-based compensation expense related to RSUs and PSUs for fiscal 2022, 2021 and 2020 was $23.9 million, $20.9 million and $17.7 million, respectively, and was included in total stock-based compensation expense. The actual income tax benefit realized from RSUs and PSUs for fiscal 2022, 2021 and 2020 was $9.1 million, $6.2 million and $3.4 million, respectively. At October 2, 2022, there was $35.9 million of unrecognized stock-based compensation costs related to nonvested RSUs and PSUs that will be substantially recognized by the end of fiscal 2025.

For fiscal 2022, 2021 and 2020, we based our expected stock price volatility on historical volatility behavior and current implied volatility behavior. The risk-free rate of return was based on constant maturity rates provided by the U.S. Treasury. The expected life was based on the ESPP terms and conditions.

Stock-based compensation expense for fiscal 2022, 2021 and 2020 included $2.3 million, $2.0 million and $1.2 million, respectively, related to the ESPP. The unrecognized stock-based compensation costs for awards granted under the ESPP at fiscal 2022 and 2021 year-ends were $0.6 million and $0.5 million, respectively. At October 2, 2022, ESPP participants had accumulated $11 million to purchase our common stock.
