Caution Concerning Forward-Looking Statements

This press release contains forward-looking statements as that term is used in the Private Securities Litigation Reform Act of 1995. These statements are based on our current expectations about future events or future financial performance. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, and often contain words such as “may,” “could,” “expect,” “intend,” “plan,” “seek,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” or “continue.” These statements involve known and unknown risks and uncertainties that may cause the events we discussed not to occur or to differ significantly from what we expected. For us, these risks and uncertainties include, among others, general industry conditions and competition, including the global financial crisis that began in 2007; the impact of market volatility on revenue from asset-based fees; damage to our reputation resulting from claims made about possible conflicts of interest; liability for any losses that result from an actual or claimed breach of our fiduciary duties; financial services industry consolidation; a prolonged outage of our database and network facilities; challenges faced by our non-U.S. operations; and the availability of free or low-cost investment information. A more complete description of these risks and uncertainties can be found in our filings with the SEC, including our Annual Report on Form 10-K for
