Safe Harbor Statement 2 Forward-LookingStatements Certain statements in this presentation are forward-looking as defined in the Private Securities Litigation Reform Act of 1995. These forward-looking statements may be identified by the fact they use words such as “should,” “expect,” “anticipate,” “estimate,” “target,” “may,” “project,” “guidance,” “intend,” “plan,” “believe” and other words and terms of similar meaning and expression. Such statements are likely to relate to, among other things, a discussion of goals, plans and projections regarding financial position, results of operations, cash flows, market position, market growth and trends, product development, product approvals, sales efforts, expenses, capital expenditures, performance or results of current and anticipated products and the outcome of contingencies such as legal proceedings and financial results. Forward-looking statements can also be identified by the fact that they do not relate strictly to historical or current facts. Such forward-looking statements are based on current expectations that involve inherent risks, uncertainties and assumptions that may cause actual results to differ materially from expectations as of the date of this presentation. These risks include, but are not limited to: (1) the ability to sustain brand strength, particularly the Enfa family of brands; (2) the effect on the company's reputation of real or perceived quality issues; (3) the effect of regulatory restrictions related to the company’s products; (4) the adverse effect of commodity costs; (5) increased competition from branded, private label, store and economy-branded products; (6) the effect of an economic downturn on consumers' purchasing behavior and customers' ability to pay for product; (7) inventory reductions by customers; (8) the adverse effect of changes in foreign currency exchange rates; (9) the effect of changes in economic, political and social conditions in the markets where we operate; (10) changing consumer preferences; (11) the possibility of changes in the Women, Infant and Children (WIC) program, or participation in WIC; (12) legislative, regulatory or judicial action that may adversely affect the company's ability to advertise its products, maintain product margins, or negatively impact the company’s reputation or result in fines or penalties that decrease earnings; and (13) the ability to develop and market new, innovative products. For additional information regarding these and other factors, see the company’s filings with the United States Securities and Exchange Commission (the SEC), including its most recent Annual Report on Form 10-K, which filings are available upon request from the SEC or at www.meadjohnson.com. The company cautions readers not to place undue reliance on any forward-looking statements, which speak only as of the date made. The company undertakes no obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise. Factors Affecting Comparability – Non-GAAP Financial Measures This presentation contains non-GAAP financial measures, which may include non-GAAP net sales, gross profit, certain components of operating expenses, EBIT, earnings and earnings per share information. The items included in GAAP measures, but excluded for the purpose of determining the above listed non-GAAP financial measures, include significant income/expenses not indicative of underlying operating results, including the related tax effect and, at times, the impact of foreign exchange. The above listed non-GAAP measures represent an indication of the company’s underlying operating results and are intended to enhance an investor’s overall understanding of the company’s financial performance and ability to compare the company’s performance to that of its peer companies. In addition, this information is among the primary indicators the company uses as a basis for evaluating company performance, setting incentive compensation targets and planning and forecasting of future periods. This information is not intended to be considered in isolation or as a substitute for financial measures prepared in accordance with GAAP. Tables that reconcile non-GAAP to GAAP disclosure are included in the Appendix. This presentation should be reviewed in conjunction with the transcript for the company’s first quarter 2016 earnings conference call as well as the company's earnings release and Form 10-Q for the first quarter of 2016.
