The risk-free interest rate represents the implied yields available from the U.S. Treasury zero-coupon yield curve over the contractual term of the option when using the trinomial option-pricing model. Expected dividend yield is 0% because the Company has not paid dividends in the past and currently has no known intention to do so in the future. Exercise factor and discount for post-vesting restrictions are based on the Company’s historical experience.

Options to purchase 25,191 shares vested during fiscal year 2025. The total fair value of options vested during fiscal years 2025 was $5.1 million.

46,927 shares vested in 2025 with a weighted average fair value of $343.91, 32,823 shares vested in 2024 with a weighted average fair value of $381.95, and 27,640 shares vested in 2023 with a weighted average fair value of $341.57.

Stock-Based Compensation

The Company uses the straight-line attribution method in recognizing stock-based compensation expense for awards that vest based on service conditions. For awards that vest subject to performance conditions, compensation expense is recognized ratably for each tranche of the award over the performance period if it is probable that performance conditions will be met.

The Company recognizes compensation expense, less estimated forfeitures. For Equity Plan awards during fiscal year 2025, the estimated forfeiture rate was 15.0% for stock options and 11.0% for restricted stock units and investment shares. For Equity Plan awards during fiscal year 2024, the estimated forfeiture rate was 16.0% for stock options and 13.0% for restricted stock units and investment shares. For Equity Plan awards during fiscal year 2023, the estimated forfeiture rate was 20.0% for stock options and 12.0% for restricted stock units and investment shares. The estimated forfeiture rates used are based upon historical experience with the various award types and the Company annually reviews these rates to ensure proper projection of future forfeitures.

Based on equity awards outstanding as of December 27, 2025, there is $39.9 million of unrecognized compensation costs, net of estimated forfeitures, related to unvested share-based compensation arrangements that are expected to vest. Such costs are expected to be recognized over a weighted-average period of 1.7 years.
