In many cases, you can identify forward-looking statements by terminology such as “may,” “will,” “plan,” “expect,” “anticipate,” “estimate,” “believe,” or “continue” or the negative of these terms or other similar words. Actual results and events could differ materially and adversely from those contained in the forward-looking statements due to a number of factors, including: uncertainties regarding our ability to execute our restructuring plans within expected costs and timing; increases in our overall debt levels as a result of the acquisition of the Power Transmission Solutions (“PTS”) business from Emerson Electric Co., or otherwise and our ability to repay principal and interest on our outstanding debt; actions taken by our competitors and our ability to effectively compete in the increasingly competitive global electric motor, power generation and mechanical motion control industries; our ability to develop new products based on technological innovation and the marketplace acceptance of new and existing products; fluctuations in commodity prices and raw material costs; our dependence on significant customers; issues and costs arising from the integration of acquired companies and businesses such as the PTS acquisition, including the timing and impact of purchase accounting adjustments; unanticipated costs or expenses we may incur related to product warranty issues; currency devaluations, non-payment of receivables, governmental restrictions such as price and margin controls, or other difficult operating conditions relating to our doing business in Venezuela; our dependence on key suppliers and the potential effects of supply disruptions; infringement of our intellectual property by third parties, challenges to our intellectual property, and claims of infringement by us of third party technologies; product liability and other litigation, or the failure of our products to perform as anticipated, particularly in high volume applications; economic changes in global markets where we do business, such as reduced demand for the products we sell, currency exchange rates, inflation rates, interest rates, recession, foreign government policies and other external factors that we cannot control; unanticipated liabilities of acquired businesses; affect on earnings of any significant impairment of goodwill or intangible assets; cyclical downturns affecting the global market for capital goods; difficulties associated with managing foreign operations; and other risks and uncertainties including but not limited to those described in Item 1A-Risk Factors of the Company’s Annual Report on Form 10-K filed on March 4, 2015 and from time to time in our reports filed with U.S. Securities and Exchange Commission.

Non-GAAP Financial Measures p 3 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. 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. In addition, since our management often uses these non-GAAP financial measures to manage and evaluate our business, make operating decisions, and forecast our future results, we believe disclosing these measures helps investors evaluate our business in the same manner as management. 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 earnings release, 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 operating profit, adjusted operating profit margin, free cash flow and free cash flow as a percentage of adjusted net income. Adjusted net income represents net income attributable to Regal Beloit Corporation adjusted to exclude non-cash items of Goodwill Impairment, Asset Impairments and Other, Net and the Venezuelan Asset Write Down. 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 less the amount of sales attributable to any divested businesses (“acquisition sales”), and the impact of foreign currency translation. The impact of foreign currency translation is determined by translating the respective period’s sales (excluding acquisition sales) using the same 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. We use the term “acquisition growth” to refer to the increase in our sales between periods that is attributable to acquisition sales.
