Item 8.01 Other Events

               GMAC 2005 AND FOURTH QUARTER 2005 EARNINGS SUMMARY

General Motors Acceptance Corporation (GMAC) earned $2.4 billion in 2005, down
$0.5 billion from record earnings of $2.9 billion earned in 2004. Earnings
include non-cash goodwill impairment charges of $439 million (after-tax), which
were recognized in the fourth quarter of 2005. The charges relate predominately
to GMAC's Commercial Finance operating segment and primarily to the goodwill
recognized in connection with the 1999 acquisition of the majority of this
business. Excluding these impairment charges, which management considers to be
non-recurring, GMAC earned $2.8 billion. Earnings were driven by record results
in GMAC's Mortgage and Insurance operations. Strong earnings were achieved
despite a difficult environment that included higher market interest rates,
declining mortgage industry volume, a series of negative rating agency actions
and the significant impact of Hurricane Katrina. GMAC continues to maintain
adequate liquidity with cash reserve balances at December 31, 2005 of 
$20 billion, comprised of $15.8 billion in cash and cash equivalents and 
$4.2 billion invested in marketable securities. GMAC continues to provide global
support for the marketing of GM vehicles, as well as provided a significant
source of cash flow to GM through the payment of a $2.5 billion dividend in 2005
including $1 billion paid in the fourth quarter.

Results for Financing operations, excluding goodwill impairment charges of 
$398 million (after-tax), were $1,064 million, down $412 million from 
$1,476 million earned in 2004. The decrease is primarily due to lower net 
interest margins as a result of increased borrowing costs. The decline in net 
interest margins was somewhat mitigated by lower consumer credit provisions, 
primarily as a result of lower asset levels, and the impact of improved used 
vehicle prices on terminating leases.

Mortgage operations earned a record $1,352 million, excluding goodwill
impairment charges of $41 million (after-tax), an increase of 22% from 
$1,108 million earned in 2004, reflecting increases in both the residential and
commercial mortgage operations. GMAC's residential mortgage businesses benefited
from increased loan production, favorable credit experience, improved mortgage
servicing results and gains on sales of mortgages. GMAC Commercial Mortgage also
experienced an increase in earnings as compared to the prior year largely due to
record loan origination volume, higher gains on sales of loans and increases in
fee and investment income.

GMAC's Insurance operations generated record net income of $417 million in 2005,
up $88 million from record earnings of $329 million earned in 2004. The increase
reflects a combination of strong results achieved through increased premium
revenue, higher capital gains and improved investment portfolio performance. In
addition, GMAC Insurance maintained a strong investment portfolio, with a market
value of $7.7 billion at December 31, 2005, including net unrealized gains of
$573 million.

GMAC's consolidated earnings for the fourth quarter of 2005 were $614 million,
excluding goodwill impairment charges, representing a $69 million decline from
2004 fourth quarter earnings of $683 million. For the quarter, net income from
Financing operations was $260 million, excluding goodwill impairment charges,
down from $323 million earned in the fourth quarter of 2004. GMAC's Mortgage
operations earned $221 million, excluding goodwill impairment charges, down from
$292 million earned in the fourth quarter of 2004. GMAC's Insurance operations
had record net income of $133 million in the fourth quarter of 2005, up
significantly from the $68 million earned in the fourth quarter of 2004.

As previously announced in October 2005, GM is pursuing the sale of a
controlling interest in GMAC to a strategic partner, with the goal of restoring
GMAC's investment grade credit rating and renewing its access to low-cost
financing. GM is currently in discussions with potential interested parties, and
the process is ongoing. GMAC also continues in the closing process of the
previously announced sale of a controlling interest in GMAC Commercial Mortgage.
Certain regulatory approvals and other closing conditions are in process and a
first quarter 2006 closing is expected.

While these statements represent our current judgment on what the future may

others, the following: the ability of General Motors ("GM"), our parent, 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
Residential Capital Corporation ("ResCap") and maintaining the mutually
beneficial relationship between GMAC and GM; significant changes in the
competitive environment and the effect of competition in the corporation's
markets, including on the corporation's pricing policies; our ability to
maintain adequate financing sources; our ability to maintain 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 Corp.; 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
us; changes in the residual value of off-lease vehicles; changes in U.S.
government -sponsored mortgage programs or disruptions in the markets in which
our mortgage subsidiaries operate; changes in our contractual servicing rights;
costs and risks associated with litigation; changes in our 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.
