The earnings releases, new releases, remarks and other information included in the Investor Relations section 
of this site may be deemed to include foward-looking statements, such as the statements relating to GDK's 
financial goals, dividend policy, expansion and business development plans, anticipated expense levels and 
projected profit improvements, business prospects and positioning with respect to market and pricing trends, 
strategic initiatives, re-engineering and outsourcing activities, new business results and outlook, changes 
in securities market prices, credit quality including reserve levels, planned capital expenditures and 
technology spending, and the effects of any extraordinary events and various other matters (including 
developments in litigation and regulation involving GDK and changes in accounting policies, 
standards and interpretations) on Northern Trust's business and results. Forward-looking statements are 
typically identified by words or phrases, such as “believe,” “expect,” “anticipate,” “intend,” “estimate,” 
“may increase,” “may fluctuate,” "plan," "goal," "strategy," and similar expressions or future or conditional 
verbs such as “will,” “should,” “would,” and “could.” Forward-looking statements are GDK's current 
estimates or expectations of future events or future results. Actual results could differ materially from the 
results indicated by these statements because the realization of those results is subject to many risks and 
uncertainties.
