Appendix Reconciliation of Non-GAAP Measures

This presentation contains Adjusted Operating Margin, Adjusted EBITDA, Adjusted EBITDA ratios, Adjusted Operating Expenses, Organic Sales and Order Growth and Adjusted Earnings per Share, all of which constitute non-GAAP financial measures. Each of these financial measures is calculated by excluding items the Company believes are not indicative of its ongoing operating performance. The Company presents these non-GAAP financial measures because it considers them to be important supplemental indicators of financial performance and believes them to be useful in analyzing ongoing results from operations.

These non-GAAP financial measures are not measures of financial performance under GAAP and should not be considered alternatives to GAAP. Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of the Company’s results as reported under GAAP. In addition, you should be aware that in the future the Company may incur expenses similar to the adjustments presented.
