Common Class B [Member] | Deferred Stock Units [Member]
Class of Stock [Line Items]
Deferred stock units, description	On November 30, 2022, the Company adopted an equity incentive program in the form of DSUs that, upon vesting, will entitle the grantees to receive shares of the Company’s Class B common stock. On December 5, 2022, the Company granted 187,975 DSUs to certain of its executive officers and employees. Subject to continued full time employment or other service to the Company, the DSUs are scheduled to vest in three equal amounts on each of May 17, 2023, February 21, 2024, and February 25, 2025. The number of shares that will be issuable on each vesting date will vary between 50% to 200% 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 price approved by the Compensation Committee of the Company’s Board of Directors based on the market price at the time of the grant. In addition, the grantee will have the right to elect a later vesting date no later than April 14, 2023 for the May 17, 2023 vesting date, and no later than January 19, 2024 for the February 21, 2024 vesting date. A grantee will have the option to elect a later vesting date for one-half or all of the shares scheduled to vest on the then upcoming vesting date and any DSUs that do not vest based in the grantee’s election, will be eligible to vest on the subsequent scheduled vesting date. The Company’s estimate of the fair value of the DSUs on the date of grant is in process. The estimated grant date fair value will be recognized on a graded vesting basis over the requisite service periods ending in February 2025.
