Context Restricted stock awards to non-employee directors are a common form of board compensation and are subject to vesting conditions (here, vesting at the next annual meeting). Because these shares are not immediately transferable until vested, such awards reflect compensation mechanics rather than an open-market purchase or sale and do not by themselves indicate the director’s trading view.
