Non-GAAP Financial Measures We prepare financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”). We also periodically disclose certain financial measures in our quarterly earnings releases, on investor conference calls, and in investor presentations and similar events that may be considered “non-GAAP” financial measures. This additional information is not meant to be considered in isolation or as a substitute for our results of operations prepared and presented in accordance with GAAP. In this presentation, we disclose the following non-GAAP financial measures, and we reconcile these measures in the tables below to the most directly comparable GAAP financial measures: adjusted diluted earnings per share (both historical and projected), adjusted income from operations, adjusted operating margin, adjusted net sales, net debt, adjusted EBITDA, adjusted net income attributable to Regal Beloit Corporation, free cash flow, and free cash flow as a percentage of adjusted net income attributable to Regal Beloit Corporation, adjusted income before taxes, adjusted provision for income taxes, adjusted effective tax rate, net sales from ongoing business, adjusted income from operations of ongoing business, ongoing business adjusted operating margin, adjusted diluted earnings per share for ongoing business and ROIC. We believe that these non-GAAP financial measures are useful measures for providing investors with additional information regarding our results of operations and for helping investors understand and compare our operating results across accounting periods and compared to our peers. Our management primarily uses adjusted income from operations, adjusted operating income, adjusted operating margin and ROIC to help us manage and evaluate our business and make operating decisions, while adjusted diluted earnings per share, net debt, adjusted EBITDA, adjusted net sales, adjusted net income attributable to Regal Beloit Corporation, free cash flow, free cash flow as a percentage of adjusted net income attributable to Regal Beloit Corporation, adjusted income before taxes, adjusted provision for income taxes, adjusted effective tax rate, net sales from ongoing business, adjusted income from operations of ongoing business, ongoing business adjusted operating margin and adjusted diluted earnings per share for ongoing business are primarily used to help us evaluate our business and forecast our future results. Accordingly, we believe disclosing and reconciling each of these measures helps investors evaluate our business in the same manner as management. In addition to these non-GAAP measures, we also use the term “organic sales” to refer to GAAP sales from existing operations excluding sales from acquired businesses recorded prior to the first anniversary of the acquisition (“net sales from business acquired") and excluding sales from business divested/to be exited (“net sales from business divested/to be exited“) recorded prior to the first anniversary of the exit and excluding the impact of foreign currency translation. The impact of foreign currency translation is determined by translating the respective period’s organic sales using the currency exchange rates that were in effect during the prior year periods. We use the term “organic sales growth” to refer to the increase in our sales between periods that is attributable to organic sales. For further clarification, we may use the term “acquisition growth” to refer to the increase in our sales between periods that is attributable to acquisition sales.
