Deferred stock units, description |  |  |  |  |  |  |  |  | The Company has an equity incentive program in the form of grants of DSUs that, upon vesting, will entitle the grantees to receive shares of the Company’s Class B common stock. The number of shares issuable on each vesting date varies between 50% to 200% of the number of DSUs that vested on that vesting date, depending on the market price for the underlying Class B common stock on the vesting date relative to the base price approved by the Compensation Committee of the Company’s Board of Directors, which is based on the market price at the time of the grants. In fiscal 2025, fiscal 2024, and fiscal 2023, in accordance with the program and based on certain elections made by grantees, the Company issued 276,960; 55,039; and 43,278 shares, respectively, of its Class B common stock for vested DSUs. The Company estimated that the fair value of the DSUs on the date of grants was an aggregate of $0.8 million, $0.8 million, and $5.4 million in fiscal 2025, fiscal 2024, and fiscal 2023, respectively, which is being recognized on a graded vesting basis over the requisite service periods. The Company uses a risk neutral Monte Carlo simulation method in its valuation of the DSUs, which simulates the range of possible future values of the Company’s Class B common stock over the life of the DSUs. |  |

Deferred stock units, description | The number of shares that will be issuable on each vesting date will vary between 50% to 267% of the number of DSUs that vest on that vesting date, depending on the market price for the underlying Class B common stock on the vesting date relative to the grant price of $50.90 per share (the price that was approved by the Compensation Committee of the Company’s Board of Directors). For certain executive officers of the Company, the number of shares that will be issuable on each vesting date will vary between 50% to 400% of the number of DSUs that vest on that vesting date. In addition, the grantee will have the option to elect a later vesting date no later than January 19, 2026 for the February 17, 2026 vesting date, and no later than January 18, 2027 for the February 16, 2027 vesting date. |  |  |  |  |  |  |  |  |  |
