Forward Looking Statement

This presentation may include forward-looking statements concerning Northern Trust’s financial results and outlook, capital adequacy, dividend policy, anticipated expense levels and technology spending, risk management policies, contingent liabilities, strategic initiatives, industry trends, and expectations regarding the impact of recent legislation. Forward-looking statements are typically identified by words or phrases such as “believe”, “expect”, “anticipate”, “intend”, “estimate”, “project”, “likely”, “may increase”, “plan”, “goal”, “target”, “strategy”, and similar expressions or future or conditional verbs such as “may”, “will”, “should”, “would”, and “could”. Forward-looking statements are Northern Trust’s current estimates or expectations of future events or future results, and involve risks and uncertainties that are difficult to predict. These statements are based on assumptions about many important factors, including the factors discussed in Northern Trust’s most recent annual report on Form 10-K and other filings with the U.S. Securities and Exchange Commission, all of which are available on Northern Trust’s website.

We caution you not to place undue reliance on any forward-looking statement as actual results may differ materially from those expressed or implied by forward-looking statements. Northern Trust assumes no obligation to update its forward-looking statements.
