ITEM 8.01 OTHER EVENTS

On December 21, 2004, Standard & Poor’s Ratings Services (“Standard & Poor’s”) lowered its corporate credit rating on Delphi to ‘BB+’ from ‘BBB-’ and its short-term corporate credit rating to ‘B’ from ‘A-3’ with a stable outlook. The ratings were removed from CreditWatch where they were placed December 2, 2004. We believe that Standard & Poor’s lowered ratings do not significantly reduce our near-term liquidity, however our overall access to certain sources, particularly commercial paper, may be further constrained and we may face increased short-term borrowing costs. In addition, as we seek to roll over our $500 million bonds due in 2006 we may face increased long-term borrowing costs. We currently have the ability to access other sources of liquidity including funding available from uncommitted lines of credit, customer receivable based financing, such as factoring, and the various committed credit facilities described in our 2004 third quarter financial statements and other information as reported on Form 8-K with the Securities and Exchange Commission on October 18, 2004.

All statements contained or incorporated in this presentation which address operating performance, events or developments that we expect or anticipate may occur in the future (including statements relating to future sales, cash flow or earnings expectations, savings expected as a result of our global restructurings or other initiatives, portfolio restructuring plans, volume growth, awarded sales contracts and customer diversification or statements expressing general optimism about future operating results) are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are made on the basis of management’s current views and assumptions with respect to future events. Important factors, risks and uncertainties which may cause actual results to differ from those expressed in our forward-looking statements are discussed in detail in our filings with the Securities and Exchange Commission, including our annual report on Form 10-K for the year ended December 31, 2003. In particular, the achievement of projected levels of revenue, earnings, cash flow and debt levels will depend on our ability to execute our portfolio and global restructuring plans in a manner which satisfactorily addresses any resultant antitrust or labor issues and customer concerns, any contingent liabilities related to divestitures or integration costs associated with acquisitions, and other matters; our continued ability to diversify our customer base and still maintain existing GM business; the continued protection and exploitation of our intellectual property to develop new products and enter new markets; and our ability to capture expected benefits of our cost reduction initiatives so as to maintain flexibility to respond to adverse and cyclical changes in general economic conditions and in the automotive industry in each market we operate, including customer cost reduction initiatives, potential increases in warranty costs, pension contributions, healthcare costs, disruptions in the labor, commodities or transportation markets caused by terrorism or war and other changes in the political and regulatory environments where we do business. Delphi does not intend or assume any obligation to update any of these forward-looking statements.
