This presentation and the accompanying presentation by management may contain forward-looking statements that are based on management's beliefs, assumptions, current expectations, estimates and projections about the financial services industry, the economy and Chemical Financial Corporation ("Chemical"). Words and phrases such as "anticipates," "believes," "continue," "estimates," "expects," "forecasts," "future," “go forward,” "intends," "is likely," "judgment," "look ahead," "look forward," "on schedule," “on track,” "opinion," "opportunity," "plans," "potential," "predicts," "probable," "projects," "should," "strategic," "trend," "will," and variations of such words and phrases or similar expressions are intended to identify such forward-looking statements. Such statements are based upon current beliefs and expectations and involve substantial risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such forward- looking statements. These statements include, among others, statements related to loan pipeline, future levels of loan charge-offs, future levels of provisions for loan losses, real estate valuation, future levels of nonperforming assets, the rate of asset dispositions, future capital levels, future dividends, future growth and funding sources, future liquidity levels, future profitability levels, future deposit insurance premiums, future asset levels, the effects on earnings of future changes in interest rates, the future level of other revenue sources, future economic trends and conditions, future initiatives to expand Chemical’s market share, expected performance and cash flows from acquired loans, future effects of new or changed accounting standards, future opportunities for acquisitions, opportunities to increase top line revenues, Chemical’s ability to grow its core franchise, future cost savings, Chemical’s ability to maintain adequate liquidity and capital based on the requirements adopted by the Basel Committee on Banking Supervision and U.S. regulators and future changes in laws and regulations applicable to Chemical and the financial services industry in general. All statements referencing future time periods are forward-looking. Management's determination of the provision and allowance for loan losses; the carrying value of acquired loans, goodwill and mortgage servicing rights; the fair value of investment securities (including whether any impairment on any investment security is temporary or other-than-temporary and the amount of any impairment); and management's assumptions concerning pension and other postretirement benefit plans involve judgments that are inherently forward-looking. There can be no assurance that future loan losses will be limited to the amounts estimated. All of the information concerning interest rate sensitivity is forward-looking. The future effect of changes in the financial and credit markets and the national and regional economies on the banking industry, generally, and on Chemical, specifically, are also inherently uncertain. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions ("risk factors") that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence. Therefore, actual results and outcomes may materially differ from what may be expressed or forecasted in such forward-looking statements. Chemical undertakes no obligation to update, amend or clarify forward-looking statements, whether as a result of new information, future events or otherwise. In addition, risk factors include, but are not limited to, the risk factors described in Item 1A of Chemical’s Annual Report on Form 10-K for the year ended December 31, 2016. These and other factors are representative of the risk factors that may emerge and could cause a difference between an ultimate actual outcome and a preceding forward-looking statement. Non-GAAP Financial Measures This presentation and the accompanying presentation by management contain certain non-GAAP financial disclosures that are not in accordance with U.S. generally accepted accounting principles ("GAAP"). Such non-GAAP financial measures include Chemical’s tangible equity to tangible assets ratio, tangible book value per share, presentation of net interest income and net interest margin on a fully taxable equivalent basis, and information presented excluding significant items, including net income, diluted earnings per share, return on average assets, return on average shareholders’ equity, return on average tangible common equity, operating expenses and efficiency ratio. Chemical uses non-GAAP financial measures to provide meaningful, supplemental information regarding its operational results and to enhance investors’ overall understanding of Chemical’s financial performance. The limitations associated with non-GAAP financial measures include the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently. These disclosures should not be considered an alternative to Chemical’s GAAP results. See the Supplemental Information included with this presentation for a reconciliation of the non-GAAP financial measures to the most directly comparable GAAP financial measures.
