Forward-Looking Statements Forward-Looking Statements : Certain of the statements made in this presentation are forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. You can identify these forward-looking statements through our use of words such as “may,” “will,” “anticipate,” “assume,” “should,” “indicate,” “would,” “believe,” “contemplate,” “expect,” “estimate,” “continue,” “plan,” “point to,” “project,” “could,” “intend,” “target” and other similar words and expressions of the future. Forward-looking statements include statements with respect to our beliefs, plans, objectives, goals, expectations, anticipations, assumptions, estimates, intentions, and future performance, and involve known and unknown risks, uncertainties and other factors, which may be beyond our control, and which may cause the actual results, performance, capital, ownership or achievements of the Bank to be materially different from future results, performance or achievements expressed or implied by such forward-looking statements due to a variety of factors, including worldwide economic conditions, the successful integration of acquisitions, success in business retention and obtaining new business and other factors. All statements other than statements of historical fact are statements that could be forward-looking statements. All forward-looking statements attributable to us are expressly qualified in their entirety by this cautionary notice, including, without limitation, those risks and uncertainties described in our Securities and Exchange Commission (“SEC”) reports and filings.

About Non-GAAP Financial Measures : This presentation contains non-GAAP financial measures including “core” net income and other financial measures presented on a “core” basis. We believe such measures provide useful information to investors that is supplementary to our financial condition, results of operations and cash flows computed in accordance with GAAP; however, our non-GAAP financial measures have a number of limitations. As such, investors should not view these disclosures as a substitute for results determined in accordance with GAAP, and they are not necessarily comparable to non-GAAP financial measures that other companies use. Reconciliations of these non-GAAP measures to corresponding GAAP financial measures are provided in the Appendix of this presentation. 2 All information in $millions and as of December 31, 2017 unless otherwise indicated .
