Such factors include, among others, the following: the ability of General Motors to complete a transaction with a strategic investor regarding a controlling interest in GMAC while maintaining a significant stake in GMAC, securing separate credit ratings and low cost funding to sustain growth for GMAC and ResCap and maintaining the mutually beneficial relationship between GMAC and General Motors; changes in economic conditions, currency exchange rates, significant terrorist attacks or political instability in the major markets where we operate; changes in the 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; and the threat of terrorism, the outbreak or escalation of hostilities between the United States and any foreign power or territory and changes in international political conditions may continue to affect both the United States and the global economy and may increase other risks. 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.
