Item  8.01  Other Events

General Motors Corporation ("GM") has been cooperating with the U.S. Securities
and Exchange Commission ("SEC") in connection with investigations reported by
the media concerning pension and Other Post-Employment Benefits ("OPEB") and
certain transactions between General Motors and Delphi Corporation ("Delphi").

The SEC has issued subpoenas to GM in connection with various matters involving
GM that it has under investigation. These matters include GM's financial
reporting concerning pension and OPEB, certain transactions between General
Motors and Delphi, GM's recovery of recall costs from suppliers and supplier
price reductions or credits, and any obligation GM may have to fund pension and
OPEB costs in connection with Delphi's proceedings under Chapter 11 of the U.S.
Bankruptcy Code.

Separately, SEC and federal grand jury subpoenas have been served on GMAC
entities in connection with industry wide investigations into practices in the
insurance industry relating to loss mitigation insurance products such as finite
risk insurance.

GM and its subsidiaries are cooperating with all these investigations. GMAC has 
no further comment at this time.
