NYSE LiquidityQuote<SUP>SM</SUP> To Debut May 21 - Dual Quoting To Begin In 28 NYSE-listed Component Stocks Of Dow Jones Industrial Average

NYSE LiquidityQuote^{SM
NYSE LiquidityQuote ("NYLQ") is a firm, two-sided, real-time quote that reflects market depth beyond the best bid or offer. NYLQ^SM will show at a single price the cumulative number of shares bid or offered on the limit-order book, in the trading-floor "crowd" and by the specialist as principal.
NYSE LiquidityQuote was developed to allow investors and market professionals to find the market "size" and depth that has become more critical since the introduction of decimal increments and penny spreads.

NYLQ will be disseminated in addition to the currently available best bid and offer via market-data vendors. NYLQ can be accessed electronically or through a broker at the point of sale and is Institutional Xpress^SM eligible.
