FORWARD-LOOKING STATEMENTS SAFE HARBOR AND NON-GAAP FINANCIAL INFORMATION Certain statements in this presentation (including statements regarding the company's forecasts, beliefs, estimates and expectations) that are not historical in nature are "forward-looking" statements within the meaning of the Private Securities Litigation Reform Act of 1995. In particular, the statements related to Timken’s plans, outlook, future financial performance, targets, projected sales, cash flows, liquidity and expectations regarding the future financial performance of the company, including the information under the headings, “2015 Outlook Update”, “Our Focus”, “2Q 2015 Net Income and Diluted EPS”, “2015 Full-Year Outlook” and “Capital Allocation” are forward-looking. The company cautions that actual results may differ materially from those projected or implied in forward-looking statements due to a variety of important factors, including: the finalization of the company's financial statements for the second quarter of 2015; the company’s ability to respond to the changes in its end markets that could affect demand for the company’s products; unanticipated changes in business relationships with customers or their purchases from the company; changes in the financial health of the company’s customers, which may have an impact on the company’s revenues, earnings and impairment charges; fluctuations in raw-material and energy costs; the impact of the company’s last-in, first-out accounting; weakness in global or regional economic conditions and financial markets; fluctuations in currency valuations; changes in the expected costs associated with product warranty claims; the ability to integrate acquired companies to achieve satisfactory operating results; the impact on operations of general economic conditions; fluctuations in customer demand; the impact on the company’s pension obligations due to the changes in interest rates, investment performance and other tactics designed to reduce risk and the company’s ability to complete and achieve the benefits of its announced plans, programs, initiatives and capital investments. Additional factors are discussed in the company’s filings with the Securities and Exchange Commission, including the company’s annual report on Form 10-K for the year ended Dec. 31, 2014, quarterly reports on Form 10-Q and current reports on Form 8-K. Except as required by the federal securities laws, the company undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

Reconciliation of EBIT to GAAP Net Income (Loss), and EBIT Margin, After Adjustments, to Net Income (Loss) as a Percentage of Sales and EBIT, After Adjustments, to Net Income (Loss): June 30, Three Months Ended The following reconciliation is provided as additional relevant information about the Company's performance. Management believes consolidated earnings (loss) before interest and taxes (EBIT) is representative of the Company's performance and that it is appropriate to compare GAAP net income (loss) to consolidated EBIT. Management also believes that EBIT and EBIT margin, after adjustments, are representative of the Company's core operations and therefore useful to investors. (1) Pension settlement charges primarily related to the purchase of a group annuity contract from Prudential on January 23, 2015, that requires Prudential to pay and administer future pension benefits for approximately 5,000 U.S. Timken retirees, as well as lump sum distributions to new retirees during the first six months of 2015.

Management believes that adjusted net income from continuing operations and diluted earnings (loss) per share, adjusted to remove: (a) pension settlement charges; (b) impairment and restructuring charges; and (c) provision (benefit) for income taxes are representative of the Company's performance and therefore useful to investors. (1) Pension settlement charges primarily related to the purchase of a group annuity contract from Prudential on January 23, 2015, that requires Prudential to pay and administer future pension benefits for approximately 5,000 U.S. Timken retirees, as well as lump sum distributions to new retirees during the first six months of 2015.

Capital, used for the ratio of total debt to capital, is defined as total debt plus total shareholders' equity. Capital, used for the ratio of net debt to capital, is defined as total debt less cash, cash equivalents and restricted cash plus total shareholders' equity. Management believes Net Debt is an important measure of the Company's financial position, due to the amount of cash and cash equivalents.
