NYSE Introduces the First Indexes Based on NYSE-Listed IPOs and Spin-Offs
Indexes Tracking Unique Growth of New Listings on the NYSE

NEW YORK , Oct. 9, 2006 – NYSE Group, Inc. (NYSE: NYX) announced the recent launch of the NYSE IPOX Composite (NYSE: IPO.ID) and NYSE IPOX U.S. Indexes (NYSE: IPY.ID), which provide investors with transparent and systematic exposure to recent initial public offerings (IPOs) and spin-offs listed on the NYSE.  Based on a modified market capitalization weighted methodology measuring the average performance of domestic and international new issues, the NYSE IPO Indexes employ unbiased entrance and exit rules based on the index methodology designed by IPOX Schuster LLC.  This rules-based methodology permits index constituents to enter the index after six trading days and exit after 1000 trading days, resulting in a benchmark of growth companies that meet the NYSE’s stringent listing standards.

In 2006, brand leaders meeting the NYSE’s listing requirements such as MasterCard Incorporated, Burger King Holdings, J. Crew Group, Qimonda AG, Ameriprise Financial Inc. and Morton's Restaurant Group made public market debuts on the NYSE. Total IPOs listed on the NYSE year to date represent a market capitalization of more than $100 billion.

“We are very pleased to introduce two new indexes that allow investors to track the performance of newly-listed companies as they begin trading on the Exchange,” said NYSE Group President and Co-COO, Catherine R. Kinney. “We created these indexes to serve as benchmarks that satisfy investors’ appetite for enhanced information products and to provide investors with unique insight into this specific segment of the NYSE’s $22.6 trillion family of listed companies.”

About NYSE IPOX Composite and NYSE IPOX U.S. Indexes:
The NYSE IPOX Composite Index, as of Sept. 29, 2006 , tracks 161 IPOs with a market cap of more than $500 billion. This includes U.S. common stocks and ADRs listing on the NYSE in connection with an IPO or spin-off on the New York Stock Exchange.

Using the same unbiased methodology, both indexes use a maximum weighting of 10% for the largest constituents and measure the average performance of domestic and foreign new listings. Index components are dynamically reconstituted to accurately reflect overall IPO and spin-off activity on the Exchange.  The base date for both indexes is Aug 31, 2006  .
