2 Forward Looking Statements Statements in this presentation that express a belief, expectation or intention, as well as those that are not historical fact, are forward-looking statements under the Private Securities Litigation Reform Act of 1995. They involve a number of risks and uncertainties that may cause actual events and results to differ materially from such forward-looking statements. These risks and uncertainties include, but are not limited to: general economic conditions in the markets served by our businesses, some of which are cyclical and experience periodic downturns; prices and availability of raw materials; and the amount of any payments required to satisfy contingent liabilities related to discontinued operations of our predecessors, including liabilities for certain products, environmental matters, guaranteed debt payments, employee benefit obligations and other matters. In addition, adverse developments could arise in regard to voluntary petitions filed by certain of our subsidiaries in U.S. Bankruptcy Court to establish a trust that would resolve all current and future asbestos claims. Our filings with the Securities and Exchange Commission, including the Form 10-K for the year ended December 31, 2009 and the Form 10-Q for the period ended September 30, 2010, describe these and other risks and uncertainties in more detail. We do not undertake to update any forward-looking statement made in this presentation to reflect any change in management's expectations or any change in the assumptions or circumstances on which such statements are based. We own a number of direct and indirect subsidiaries and, from time to time, we may refer collectively to EnPro and one or more of our subsidiaries as "we" or to the businesses, assets, debts or affairs of EnPro or a subsidiary as "ours." These and similar references are for convenience only and should not be construed to change the fact that EnPro and each subsidiary is an independent entity with separate management, operations, obligations and affairs. This presentation also contains certain non-GAAP financial measures as defined by the Securities Exchange Commission. A reconciliation of these measures to the most directly comparable GAAP equivalents is included as an appendix to this presentation.
