Under this compensation arrangement, non-employee directors receive (1) an annual cash retainer equal to $120,000 (or, if elected by the director, deferred stock in lieu of all or a portion of the cash retainer), and (2) an annual grant of deferred stock with a grant date fair value of approximately $180,000 (or, if elected by the director, a grant of restricted stock).
