Cautionary statement regarding forward-looking information
Certain statements in this communication are forward-looking statements under the United States
Private Securities Litigation Reform Act of 1995 (and are made pursuant to the safe harbor
provisions of such Act) and applicable Canadian securities legislation. These forward-looking
statements include, but are not limited to, statements with respect to the expected closing of the
proposed acquisition of M&I, plans for the acquired business and the financial impact of the
acquisition and are typically identified by words such as believe, expect, anticipate,
intend, estimate, plan, will, should, may, could and other similar expressions.
By their nature, forward-looking statements are based on various assumptions and are subject to
inherent risks and uncertainties. We caution readers of this communication not to place undue
reliance on our forward-looking statements as the assumptions underlying such statements may not
turn out to be correct and a number of factors could cause actual future results, conditions,
actions or events to differ materially from the targets, expectations, estimates or intentions
expressed in the forward-looking statements.
Such factors include, but are not limited to: the possibility that the proposed transaction does
not close when expected or at all because required regulatory, shareholder or other approvals and
other conditions to closing are not received or satisfied on a timely basis or at all; the terms of
the proposed transaction may need to be modified to satisfy such approvals or conditions; the
anticipated benefits from the proposed transaction such as it being accretive to earnings,
expanding our North American presence and cost savings and synergies are not realized in the time
frame anticipated or at all as a result of changes in general economic and market conditions,
interest and exchange rates, monetary policy, laws and regulations (including changes to capital
requirements) and their enforcement, and the degree of competition in the geographic and business
areas in which M&I operates; the ability to promptly and effectively integrate the businesses of
M&I and BMO; reputational risks and the reaction of M&Is customers to the transaction; diversion
of management time on merger-related issues; increased exposure to exchange rate fluctuations; and
those other factors set out on pages 29 and 30 of BMOs 2010 Annual Report. A significant amount of
M&Is business involves making loans or otherwise committing resources to specific companies,
industries or geographic areas. Unforeseen events affecting such borrowers, industries or
geographic areas could have a material adverse effect on the performance of our integrated U.S.
operations.
Assumptions about the performance of the Canadian and U.S. economies as well as overall market
conditions and their combined effect on the banks business are material factors we consider when
determining our strategic priorities, objectives and expectations for our business. In determining
our expectations for economic growth, both broadly and in the financial services sector, we
primarily consider historical economic data provided by the Canadian and U.S. governments and their
agencies.
BMO does not undertake to update any forward-looking statement, whether written or oral, that may
be made, from time to time, by the organization or on its behalf, except as required by law.
