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, adjusted income from operations, adjusted operating margin, adjusted net sales, net debt, adjusted EBITDA, adjusted EBITDA margin, adjusted bank EBITDA, adjusted net income attributable to Regal Rexnord Corporation, free cash flow, free cash flow as a percentage of adjusted net income attributable to Regal Rexnord Corporation (or free cash flow conversion), adjusted income before taxes, adjusted provision for income taxes and adjusted effective tax rate. 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, and adjusted operating margin to help us manage and evaluate our business and make operating decisions, while adjusted diluted earnings per share, net debt, adjusted EBITDA, adjusted EBITDA margin, adjusted bank EBITDA, adjusted net sales, adjusted net income attributable to Regal Rexnord Corporation, free cash flow, free cash flow as a percentage of adjusted net income attributable to Regal Rexnord Corporation, adjusted income before taxes, adjusted provision for income taxes and adjusted effective tax rate 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 use the term “organic sales growth” to refer to the increase in our sales between periods that is attributable to organic sales. “Organic sales” to refers to GAAP sales from existing operations excluding any sales from acquired businesses recorded prior to the first anniversary of the acquisition and excluding any 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.
