ITEM 8.01.  OTHER EVENTS

On October 10, 2005, Standard & Poor's lowered their ratings of General Motors
Corporation (GM). Their press release follows.

GM Rating Lowered to `BB-`, Still Watch Negative; GMAC Rating Unchanged, Now
Watch Developing

NEW YORK (Standard & Poor's) Oct. 10, 2005--Standard & Poor's Ratings Services
said today that it lowered its long-term corporate credit rating on General
Motors Corp. (GM) to 'BB-' from 'BB' and its short-term corporate credit rating
to 'B-2' from 'B-1'. These ratings remain on CreditWatch with negative
implications, where they were placed on October 3.

The ratings of General Motors Acceptance Corp. (GMAC), and all GMAC-related
entities, including Residential Capital Corp. (ResCap) are not changed (see
list below). These ratings remain on CreditWatch but the implications are
changed from negative to developing, which means that the ratings could be
raised or lowered. The potential for downgrades of GMAC and ResCap does not
reflect deterioration in their operating performance or financial condition,
but stems strictly from the downgrade of parent GM. The potential for upgrades
depends on these entities achieving substantial separation from their
parent--through strategic actions that would alter the ownership and control of
the subsidiaries. Such an outcome now seems more likely to occur, given the
increased challenges that GM is facing.

Consolidated debt outstanding totaled $284 billion at June 30, 2005.

"The downgrade follows Delphi Corp.'s bankruptcy filing, repercussions of which
could impede GM's efforts to turn around its ailing North American automotive
operations," said Standard & Poor's credit analyst Scott Sprinzen.

GM will likely face demands from Delphi for price relief on components GM
sources from Delphi. Absent such price concessions, GM's operations could be
disrupted by actions on the part of Delphi to reject certain supply contracts
with GM. GM also is exposed to the risk of supply disruptions caused by labor
strife at Delphi, as Delphi seeks to downsize its workforce and reduce wage
rates. In addition, developments at Delphi could adversely affect GM's own
labor relations, at a time when GM continues to seek concessions from the UAW
to reduce GM's burdensome health care costs. Moreover, GM will likely have to
assume a portion of Delphi's pension and retiree medical obligations --
obligations which GM has guaranteed. GM may ultimately be able to reduce its
purchased materials costs as a result of Delphi's restructuring and GM's
ability to transfer components sourcing to other suppliers; however, any such
saving will take a number of years to materialize, at best.

The continuing CreditWatch review reflects other concerns about the state of
GM's North American business, amid sharply deteriorating product mix and sales
volume, and prospects for persisting severe pricing pressure. We believe
soaring gasoline prices after Hurricanes Katrina and Rita are leading to an
accelerating decline in demand for SUVs. GM will soon launch a family of
all-new midsize and large SUVs. Given GM's disproportionate reliance on
SUV-related earnings, its ability to return to meaningful profitability in its
automotive business will be heavily influenced by the success of these new
models, despite GM's efforts to strengthen its product offerings in other
segments.
