Context

• A gift to a family trust is a non-market transaction and does not necessarily indicate the insider’s view on the stock. As a 10% owner and trustee who remains the beneficial owner of the shares in the trust, this is largely an estate/tax/ownership-structure move rather than a typical buy/sell trade.
