Deferred stock units, description |  |  |  |  |  |  | On November 30, 2022, the Company adopted an equity incentive program (under its 2015 Stock Option and Incentive Plan) in the form of grants of deferred stock units (“DSUs”) that, upon vesting, entitled the grantees to receive shares of the Company’s Class B common stock. The number of shares issuable on each vesting date varied 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 of $25.45 per share (which was based on the market price at the time of the initial grants under this program). On February 25, 2025, in accordance with the program and based on certain elections made by grantees, the Company issued 276,960 shares of its Class B common stock for vested DSUs, which was the final vesting date under this program. |  |  |
