APPENDIX

21 DISCLAIMER Colfax has provided financial information that has not been prepared in accordance with GAAP. These non-GAAP financial measures are adjusted net income, adjusted net income per share, adjusted operating income, organic sales growth (decline) and organic order growth (decline). Adjusted net income, adjusted net income per share and adjusted operating income exclude asbestos coverage litigation expense, expenses related to major restructuring programs and expenses and significant year-one fair value adjustment amortization expense related to the Charter acquisition, to the extent they impact the periods presented. The effective tax rates used to calculate adjusted net income and adjusted net income per share are 30.5% for the first quarter of 2013 and 31% for the first quarter of 2012. Organic sales growth (decline) and organic order growth (decline) exclude the impact of acquisitions and foreign exchange rate fluctuations. These non-GAAP financial measures assist Colfax in comparing its operating performance on a consistent basis because, among other things, they remove the impact of asbestos insurance coverage issues and expenses, expenses and year-one fair value adjustment amortization expense related to the Charter acquisition and major restructuring programs. Sales and order information by end market are estimates. We periodically update our customer groupings order to refine these estimates.

22 NON-GAAP RECONCILIATION (unaudited) (1) The effective tax rates used to calculate adjusted net income and adjusted net income per share are 30.5% and 31% for the first quarter of 2013 and 2012, respectively. (2) Adjusted net income per share was calculated consistent with the two-class method in accordance with GAAP as the Series A preferred stock are considered participating securities. Losses are not allocated to the preferred stock. _____________________ Note: Dollars in thousands, except per share amounts.
