Insights

Corporate Governance Analyst

Director received RSUs as fee payment; shares are deferred under the director program.

The transaction records a non-cash grant: 977 Class A shares were recorded as acquired at $0.00, indicating restricted stock units granted in lieu of cash retainer fees. These awards increase the director's beneficial stake to 97,543 shares, including 46,731 RSUs held separately.

Because issuance is deferred per the program terms, the economic and voting rights timing depends on those deferral provisions; monitor the plan schedule for actual delivery and any vesting or distribution dates over the next reporting periods.
