2 Forward looking statements Reconciliation and use of non-GAAP measures to U.S. GAAP This presentation may contain “forward-looking statements,” which include information concerning the company's plans, objectives, goals, strategies, future revenues or performance, capital expenditures, financing needs and other information that is not historical information. When used in this presentation, the words “outlook,” “forecast,” “estimates,” “expects,” “anticipates,” “projects,” “plans,” “intends,” “believes,” “may,” “can,” “could,” “might,” “will” and variations of such words or similar expressions are intended to identify forward-looking statements. All forward-looking statements are based upon current expectations and beliefs and various assumptions. There can be no assurance that the company will realize these expectations or that these beliefs will prove correct. There are a number of risks and uncertainties that could cause actual results to differ materially from the results expressed or implied in the forward-looking statements contained in this presentation. These risks and uncertainties include, among other things: changes in general economic, business, political and regulatory conditions in the countries or regions in which we operate; the length and depth of business cycles, particularly in the automotive, electrical, electronics and construction industries; changes in the price and availability of raw materials; the ability to pass increases in raw material prices on to customers or otherwise improve margins through price increases; the ability to maintain plant utilization rates and to implement planned capacity additions and expansions; the ability to improve productivity by implementing technological improvements to existing plants; increased price competition and the introduction of competing products by other companies; market acceptance of our technology; the ability to obtain governmental approvals and to construct facilities on terms and schedule acceptable to the company; changes in the degree of intellectual property and other legal protection afforded to our products; compliance and other costs and potential disruption or interruption of production or operation due to accidents, cyber security incidents, terrorism or political unrest or other unforeseen events or delays in construction or operation of facilities; potential liability for remedial actions and increased costs under existing or future environmental regulations, including those relating to climate change; potential liability resulting from pending or future litigation, or from changes in the laws, regulations or policies of governments or other governmental activities in the countries in which we operate; changes in currency exchange rates and interest rates; and various other factors discussed from time to time in the company's filings with the Securities and Exchange Commission. Any forward-looking statement speaks only as of the date on which it is made, and the company undertakes no obligation to update any forward-looking statements to reflect events or circumstances after the date on which it is made or to reflect the occurrence of anticipated or unanticipated events or circumstances. Reconciliation of Non-U.S. GAAP Measures to U.S. GAAP This presentation reflects the following performance measures: operating EBITDA, business operating EBITDA, affiliate EBITDA and proportional affiliate EBITDA, adjusted earnings per share, net debt and adjusted free cash flow as non-U.S. GAAP measures. These measurements are not recognized in accordance with U.S. GAAP and should not be viewed as an alternative to U.S. GAAP measures of performance. The most directly comparable financial measure presented in accordance with U.S. GAAP in our consolidated financial statements for operating EBITDA and business operating EBITDA is net income; for proportional affiliate EBITDA is equity in net earnings of affiliates; for affiliate EBITDA is operating profit; for adjusted earnings per share is earnings per common share-diluted; for net debt is total debt; and for adjusted free cash flow is cash flow from operating activities. Use of Non-U.S. GAAP Financial Information ► Operating EBITDA is defined by the company as net earnings less interest income plus loss (earnings) from discontinued operations, interest expense, taxes, and depreciation and amortization, and further adjusted for Other Charges and Adjustments as described in Table 7. We present operating EBITDA because we consider it an important supplemental measure of our operations and financial performance. We believe that operating EBITDA is more reflective of our operations as it provides transparency to investors and enhances period-to-period comparability of our operations and financial performance. Operating EBITDA is one of the measures management uses for its planning and budgeting process to monitor and evaluate financial and operating results and for the company's incentive compensation plan. Operating EBITDA should not be considered as an alternative to net income determined in accordance with U.S. GAAP. We may provide guidance on operating EBITDA and are unable to reconcile forecasted operating EBITDA to a U.S. GAAP financial measure because a forecast of Other Charges and Adjustments is not practical. ► Business operating EBITDA is defined by the company as net earnings less interest income plus loss (earnings) from discontinued operations, interest expense, taxes and depreciation and amortization, and further adjusted for Other Charges and Adjustments as described in Table 7, less equity in net earnings of affiliates, dividend income from cost investments and other (income) expense. This supplemental performance measure reflects the operating results of the company's operations without regard to the financial impact of its equity and cost investments. ► Affiliate EBITDA is defined by the company as operating profit plus the depreciation and amortization of its equity affiliates. Proportional affiliate EBITDA is defined by the company as the proportional operating profit plus the proportional depreciation and amortization of its equity investments. The company has determined that it does not have sufficient ownership for operating control of these investments to consider their results on a consolidated basis. The company believes that investors should consider proportional affiliate EBITDA as an additional measure of operating results. ► Adjusted earnings per share is a measure used by management to measure performance. It is defined by the company as net earnings (loss) available to common shareholders plus preferred dividends, adjusted for other charges and adjustments, and divided by the number of basic common shares, diluted preferred shares, and options valued using the treasury method. We may provide guidance on an adjusted earnings per share basis and are unable to reconcile forecasted adjusted earnings per share to a U.S. GAAP financial measure without unreasonable effort because a forecast of Other Items is not practical. We believe that the presentation of this non-U.S. GAAP measure provides useful information to management and investors regarding various financial and business trends relating to our financial condition and results of operations, and that when U.S. GAAP information is viewed in conjunction with non-U.S. GAAP information, investors are provided with a more meaningful understanding of our ongoing operating performance. Note: The income tax rate used for adjusted earnings per share approximates the midpoint in a range of forecasted tax rates for the year. This range may include certain partial or full-year forecasted tax opportunities, where applicable, and specifically excludes changes in uncertain tax positions, discrete items and other material items adjusted out of our U.S. GAAP earnings for adjusted earnings per share purposes, and changes in management's assessments regarding the ability to realize deferred tax assets. We analyze this rate quarterly and adjust if there is a material change in the range of forecasted tax rates; an updated forecast would not necessarily result in a change to our tax rate used for adjusted earnings per share. The adjusted tax rate is an estimate and may differ from the tax rate used for U.S.GAAP reporting in any given reporting period. It is not practical to reconcile our prospective adjusted tax rate to the actual U.S. GAAP tax rate in any given future period. ► Net debt is defined by the company as total debt less cash and cash equivalents. We believe that the presentation of this non-U.S. GAAP measure provides useful information to management and investors regarding changes to the company's capital structure. Our management and credit analysts use net debt to evaluate the company's capital structure and assess credit quality. Proportional net debt is defined as our proportionate share of our affiliates' net debt. ► Adjusted free cash flow is defined by the company as cash flow from operations less capital expenditures, other productive asset purchases, operating cash from discontinued operations and certain other charges and adjustments. We believe that the presentation of this non-U.S. GAAP measure provides useful information to management and investors regarding changes to the company’s cash flow. Our management and credit analysts use adjusted free cash flow to evaluate the company’s liquidity and assess credit quality. Results Unaudited The results presented in this presentation, together with the adjustments made to present the results on a comparable basis, have not been audited and are based on internal financial data furnished to management. Quarterly results should not be taken as an indication of the results of operations to be reported for any subsequent period or for the full fiscal year.
