      To further facilitate the orderly representation of MOC orders, duringmonthly expirations the NYSE announces MOC order imbalances of 50,000shares or more for a group of "pilot" stocks. The pilot stocks consist ofthe 50 New York Stock Exchange S&P stocks with the highest marketcapitalization plus any other component stocks of the of the Major Marketindex. The imbalance announcements are disseminated (via the Tape) as soonas possible after 3:00 p.m., after 3:30 p.m., and again after 3:45 p.m.Once an imbalance announcement has been made, only MOC orders on theopposite side of the published imbalance are accepted. For pilot stockswith MOC order imbalances of less than 50,000 shares, a "no imbalance"notice is published, and thereafter no MOC orders are accepted. Finally, toincrease the flow of information on non-expiration trading days, the NYSEdisseminates, on every trading day, pilot stock MOC order imbalances of50,000 shares or more as soon as possible after 3:45 p.m.
