Context
A gift/transfer to a family trust is not a sale and does not generate proceeds; such transactions often relate to estate or family planning. Gifts generally do not signal the insider’s view on the company’s near-term prospects. As a 10% owner and trustee, Chang’s beneficial ownership remains tied to the transferred shares per the filing.
