Armstrong competes globally in many diverse markets. References to "market" or "share" data are simply estimations based on a combination of internal and external sources and assumptions.

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 2012 was used for all currency translations in 2012 and prior years. Guidance is presented using the 2013 budgeted exchange rate for the year. 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 39% for 2013 guidance, 40% for 2012, and 42% for 2011, which are based on the expected full year historical tax rate. In the fourth quarter of 2012, we completed the sale of Cabinets business. The financial results of the Cabinets business, which were previously shown as a separate reporting segment, have been reclassified and presented as discontinued operations. The financial results included within this presentation, including historical results, are presented on a continuing operations basis unless specifically noted otherwise.
