Other than statements of historical fact, all statements in this chart presentation and in related comments, including without limitation, statements about future events and financial performance, are forward-looking statements that involve certain risks and uncertainties. While these statements represent our current judgment on possible future events, and we believe that when we made these judgments they were reasonable, these statements are not guarantees of any events or financial results, and GM’s actual results may differ materially due to numerous important factors that may be revised or supplemented in subsequent reports on SEC Forms 10-Q and 8-K. Such factors include, among others, the following: the ability of GM to realize production efficiencies, to achieve reductions in costs as a result of the turnaround restructuring, health care cost reductions and an accelerated attrition program and to implement capital expenditures at levels and times planned by management; the pace of product introductions; market acceptance of the Corporation’s new products; significant changes in the competitive environment and the effect of competition in the Corporation’s markets, including on GM’s pricing policies; our ability to maintain adequate liquidity and financing sources and an appropriate level of debt; restrictions on GMAC’s and ResCap’s ability to pay dividends and prepay subordinated debt obligations to us; changes in the existing, or the adoption of new, laws, regulations, policies or other activities of governments, agencies and similar organizations where such actions may affect the production, licensing, distribution or sale of our products, the cost thereof or applicable tax rates; costs and risks associated with litigation; the final results of investigations and inquiries by the SEC; changes in our accounting principles, or their application or interpretation, and our ability to make estimates and the assumptions underlying the estimates, including the range of estimates for the Delphi pension benefit guarantees, which could result in an impact on earnings; changes in relations with unions and employees/retirees and the legal interpretations of the agreements with those unions with regard to employees/retirees; negotiations and bankruptcy court actions with respect to Delphi’s obligations to GM, negotiations with respect to GM’s obligations under the pension benefit guarantees to Delphi employees, and GM’s ability to recover any indemnity claims against Delphi; labor strikes or work stoppages at GM or its key suppliers such as Delphi or financial difficulties at GM’s key suppliers such as Delphi; additional credit rating downgrades and the effects thereof; our ability to complete the sale of a 51-percent controlling interest in GMAC and the effect of that sale on the results of GM’s and GMAC’s operations and liquidity; other factors affecting financing and insurance operating segments’ results of operations and financial condition such as credit ratings, adequate access to the market, changes in the residual value of off-lease vehicles, changes in U.S. government -sponsored mortgage programs or disruptions in the markets in which its mortgage subsidiaries operate, and changes in its contractual servicing rights; shortages of and price increases for fuel; and changes in economic conditions, commodity prices, currency exchange rates or political stability in the markets in which we operate. In addition,GMAC’s actual results may differ materially due to numerous important factors that are described in GMAC’s most recent report on SEC Form 10-K, which may be revised or supplemented in subsequent reports on SEC Forms 10-Q and 8-K. Such factors include, among others, the following: the ability of GM to complete the sale of a 51-percent controlling interest in GMAC; significant changes in the competitive environment and the effect of competition in GMAC’s and GM’s markets, including on GMAC’s and GM’s pricing policies;GMAC’s ability to maintain adequate financing sources and an appropriate level of debt; the profitability and financial condition of GM, including changes in production or sales of GM vehicles, risks based on GM’s contingent benefit guarantees and the possibility of labor strikes or work stoppages at GM or at key suppliers such as Delphi; funding obligations under GM and its subsidiaries’ qualified U.S. defined benefits pension plans; restrictions on ResCap’s ability to pay dividends and prepay subordinated debt obligations to GMAC; changes in the residual value of off-lease vehicles; changes in U.S. government-sponsored mortgage programs or disruptions in the markets in which GMAC’s mortgage subsidiaries operate; changes in GMAC’s contractual servicing rights; costs and risks associated with litigation; changes in GMAC’s accounting assumptions that may require or that result from changes in the accounting rules or their application, which could result in an impact on earnings; changes in the credit ratings of GMAC or GM; the threat of natural calamities; changes in economic conditions, currency exchange rates or political stability in the markets in which we operate; and changes in the existing, or the adoption of new, laws, regulations, policies or other activities of governments, agencies and similar organizations. Use of the term “loans” describes products associated with direct and indirect lending activities of GMAC’s global operations. The specific products include retail installment sales contracts, loans, lines of credit, leases or other financing products. The term “originate” refers to GMAC’s purchase, acquisition or direct origination of various “loan” products. Investors are cautioned not to place undue reliance on forward-looking statements.
