Non-GAAP financial measures do not replace and are not superior to the presentation of GAAP financial results, but are provided to (i) present the effects of certain merger expenses, exit costs, the BlueNext tax settlement, disposal activities and discrete tax items, and (ii) improve overall understanding of NYSE Euronext’s current financial performance and its prospects for the future. Specifically, NYSE Euronext believes the non-GAAP financial results provide useful information to both management and investors regarding certain additional financial and business trends relating to financial condition and operating results. In addition, management uses these measures for reviewing financial results and evaluating financial performance. The non-GAAP adjustments for all periods presented are based upon information and assumptions available as of the date of this release.
