Context

• Code D indicates a disposition of shares to the issuing company (a buyback/repurchase) rather than a sale into the open market. Such transactions are contractual and can reflect a negotiated sale rather than routine insider selling.
• The reporting entity is an institutional/reporting advisor with a board representative, so this is an institutional/director transaction rather than an individual executive exercising options or receiving grants.
