NYSE Euronext Declares Quarterly Dividend

NEW YORK--(BUSINESS WIRE)--The NYSE Euronext (NYX) Board of Directors today declared a quarterly cash dividend of $0.30 per share for the third quarter of 2010. The third quarter 2010 dividend is payable September 30, 2010 to shareholders of record as of the close of business on September 15, 2010. The anticipated ex-date will be September 13, 2010.

Dividend Currency Election

As a convenience to its European shareholders, NYSE Euronext has offered registered shareholders domiciled in Europe and shareholders that hold their shares through Euroclear France the ability to elect payment of the dividend in euros. The dividend will be converted from U.S. dollars to euros at an exchange rate prevailing on a date near the anticipated respective dividend payment dates. To the extent that such shareholders do not make an election, the dividend will be paid by NYSE Euronext in U.S. dollars.

In order to elect to receive the dividend in euros, registered shareholders domiciled in Europe must complete a NYSE Euronext currency election form. Registered shareholders may also elect to receive their dividends via electronic funds transfer. Forms for these elections have been sent to registered shareholders by NYSE Euronext’s transfer agent, Computershare, and are available on https://www-us.computershare.com/investor (click “Register Now” to sign up for access to your account). Shareholders that hold their shares through Euroclear France that wish to elect to receive the dividend in Euros must contact their broker.

Tax Information

The United States Internal Revenue Service requires that all non-resident alien investors certify their foreign status by completing a Form W-8BEN. A Form W-8BEN is also required in order to claim, if applicable, a reduced rate of withholding as a resident of a foreign country with which the United States has an income tax treaty. Failure to provide a completed Form W-8BEN may result in the imposition of U.S. backup withholding taxes on dividend payments to your account.

Registered holders will receive the Form W-8BEN from Computershare or they can download it on https://www-us.computershare.com/investor. Shareholders that hold their shares through a Euroclear participant must contact their broker to obtain the Form W-8BEN.
