Forward-Looking Statements; Non-GAAP; New Accounting Standards Forward-Looking Statements: This presentation contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.  These statements include, but are not limited to, descriptions of Old National Bancorp’s (“Old National’s”) financial condition, results of operations, asset and credit quality trends and profitability.  Forward-looking statements can be identified by the use of the words “anticipate,” “believe,” “expect,” “intend,” “could” and “should,” and other words of similar meaning.  These forward-looking statements express management’s current expectations or forecasts of future events and, by their nature, are subject to risks and uncertainties. There are a number of factors that could cause actual results to differ materially from those in such statements.  Factors that might cause such a difference include, but are not limited to: expected cost savings, synergies and other financial benefits from the merger with Anchor-Minnesota that might not be realized within the expected timeframes and costs or difficulties relating to integration matters might be greater than expected;  market, economic, operational, liquidity, credit and interest rate risks associated with Old National’s business; competition; government legislation and policies (including the impact of the Dodd-Frank Wall Street Reform and Consumer Protection Act and its related regulations); ability of Old National to execute its business plan; changes in the economy which could materially impact credit quality trends and the ability to generate loans and gather deposits; failure or circumvention of our internal controls; failure or disruption of our information systems; significant changes in accounting, tax or regulatory practices or requirements; new legal obligations or liabilities or unfavorable resolutions of litigations; disruptive technologies in payment systems and other services traditionally provided by banks; computer hacking and other cybersecurity threats; other matters discussed in this presentation; and other factors identified in our Annual Report on Form 10-K and other periodic filings with the SEC.  These forward-looking statements are made only as of the date of this presentation, and Old National does not undertake an obligation to release revisions to these forward-looking statements to reflect events or conditions after the date of this presentation. Non-GAAP: These slides contain non-GAAP financial measures. For purposes of Regulation G, a non-GAAP financial measure is a numerical measure of the registrant's historical or future financial performance, financial position or cash flows that excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the statement of income, balance sheet or statement of cash flows (or equivalent statements) of the registrant; or includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented. In this regard, GAAP refers to generally accepted accounting principles in the United States. Pursuant to the requirements of Regulation G, Old National Bancorp has provided reconciliations within the slides, as necessary, of the non-GAAP financial measure to the most directly comparable GAAP financial measure. New Accounting Standards: For the three months ended March 31, 2018, amounts reflect the reclassification of $0.5 million of agency costs from data processing expense to investment product fee revenue as a result of the implementation of the revenue recognition accounting standard.
