“NYSE Group experienced an extraordinary year in 2006. Beginning with the close of the Archipelago transaction and subsequent secondary offering which established the NYSE Group as a public company, we are successfully transforming the NYSE,” said NYSE Group chief financial officer and executive vice president, Nelson Chai.

“Our recently announced agreement to acquire 5% of the National Stock Exchange, India’s largest financial marketplace, and our strategic alliance with the Tokyo Stock Exchange are a strong start to the new year,” Chai added. “In 2007, we will finalize the roll out of our Hybrid Market, deliver against the integration targets in conjunction with the Archipelago transaction and complete the Euronext transaction. We will continue to improve our business model and lead the global transformation of the exchange landscape in order to benefit our investors, listed companies and market professionals.”
