Those statements provide our future expectations or forecasts and can be identified by our use of words such as "anticipate," "estimate," "expect," "project," "intend," "plan," "believe," "outlook," and other words or phrases of similar meaning in connection with any discussion of future operating or financial performance. Forward-looking statements, by their nature, address matters that are uncertain and involve risks because they relate to events and depend on circumstances that may or may not occur in the future. A more detailed discussion of the risks and uncertainties that may affect our ability to achieve the projected performance is included in the "Risk Factors" and "Management's Discussion and Analysis" sections of our recent reports on Forms 10-K and 10-Q filed with the SEC. As a result, our actual results may differ materially from our expected results and from those expressed in our forward-looking statements. Forward-looking statements speak only as of the date they are made. We undertake no obligation to update any forward-looking statements beyond what is required under applicable securities law. In addition, we will be referring to non-GAAP financial measures within the meaning of SEC Regulation G. A reconciliation of the differences between these measures with the most directly comparable financial measures calculated in accordance with GAAP are included within this presentation and available on the Investor Relations of our website at www.armstrong.com. The guidance in this presentation is only effective as of the date given, April 30, 2012, and will not be updated or affirmed unless and until we publicly announce updated or affirmed guidance. 2

All figures throughout the presentation are in $ millions unless otherwise noted. Figures may not add due to rounding. Basis of Presentation Explanation When reporting our financial results within this presentation, we make several adjustments. Management uses the non-GAAP measures below in managing the business and believes the adjustments provide meaningful comparisons of operating performance between periods. As reported results will be footnoted throughout the presentation. 3 We report in comparable dollars to remove the effects of currency translation on the P&L. The budgeted exchange rate for the current year is used for all currency translations in the current year and prior years. We remove the impact of discrete expenses and income. Examples include plant closures, restructuring actions, and other large unusual items. Taxes for normalized Net Income and EPS are calculated using a constant 40% for 2012 and 42% for 2011, which are based on the full year historical tax rate.
