Full dividend reinvestment — All cash dividendspayable on shares held in the Plan, along with anyshares held in physical certificate form or throughbook-entry Direct Registration Shares (“DRS”), willbe used to purchase additional shares. Theparticipant will not receive cash dividends fromComcast; instead, all dividends will be reinvested.Whole and fractional shares will be allocated to thePlan account.
