Safe Harbor Statement Any statements in this presentation and the oral statements relating to this presentation (the "Presentation") that are not historical facts are forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995. Words such as "expect", "believe", "anticipate", "intend", "estimate", "project", "plan", "outlook", "may", "could", "would", and similar expressions are intended to identify forward-looking statements. These forward-looking statements are predicated on the beliefs and assumptions of Comerica's management as of the date of this Presentation and do not purport to speak as of any other date. Forward- looking statements may include descriptions of plans and objectives of Comerica's management for future or past operations, products or services, and forecasts of Comerica's revenue, earnings or other measures of economic performance, including statements of profitability, business segments and subsidiaries, estimates of credit trends and global stability. Such statements reflect the view of Comerica's management as of this date with respect to future events and are subject to risks and uncertainties. Should one or more of these risks materialize or should underlying beliefs or assumptions prove incorrect, the Company's actual results could differ materially from those discussed. Factors that could cause or contribute to such differences are changes in the pace of an economic recovery and related changes in employment levels, the effects of war and other armed conflicts or acts of terrorism, implementation of Comerica's strategies and business models, management's ability to maintain and expand customer relationships, changes in the accounting treatment of any particular item, the impact of regulatory examinations, changes in the businesses or industries in which Comerica has a concentration of loans, the anticipated performance of any new banking branches, the entry of new competitors in Comerica's markets, changes in the level of fee income, changes in applicable laws and regulations, including those concerning taxes, banking, securities and insurance, changes in trade, monetary and fiscal policies, including the interest rate policies of the Board of Governors of the Federal Reserve System, fluctuations in inflation or interest rates, changes in general economic conditions and related credit and market conditions and adverse conditions in the stock market. Comerica cautions that the foregoing list of factors is not exclusive. Forward-looking statements speak only as of the date they are made. Comerica does not undertake to update forward-looking statements to reflect facts, circumstances, assumptions or events that occur after the date the forward-looking statements are made. For any forward-looking statements made in this presentation or in any documents, Comerica claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.
