Consistent with its policy of using primary exchange pricing, Standard & Poor's uses the primary exchange at NASDAQ for pricing in the calculation of its indices; vendors designate these prices with the letter "Q." No third market prices are used. End of day values are calculated using the last reported regular hours Nasdaq last sale, which would be no later than 4:00.00. Since there is a 90 second window during which trades may be reported, the Nasdaq last sale will be posted no later than 4:01:30.
