ITEM 8.01.  OTHER EVENTS

On March 29, 2006, Standard & Poor's (S&P) placed all its ratings on General
Motors Corporation (GM) on CreditWatch. Moody's Investors Services, Inc.
(Moody's) lowered their rating of GM, but left General Motors Acceptance
Corporation (GMAC) and Residential Capital Corporation (ResCap) unaffected.
Their press releases follow.

Research Update: General Motors Corp.'s Ratings On Watch Neg; Restatements
Could Affect Access To Credit

Credit Rating: B/Watch Neg/B-3

On March 29, 2006, Standard & Poor's Ratings Services placed all its ratings on
General Motors Corp. (GM), including its 'B' long-term and 'B-3' short-term
corporate credit ratings, on CreditWatch with negative implications. This action
stems from GM's disclosure in its 2005 10-K that the recent restatement of its
previous financial statements raises potential issues regarding access to its
$5.6 billion standby credit facility, as well as the possibility that certain
lease obligations of as much as $3 billion could be subject to possible claims
of acceleration, termination, or other remedies. At a minimum, GM could have to
seek waivers on financial reporting requirements from lenders, which could put
pressure on its liquidity. We understand that no similar issues exist under
General Motors Acceptance Corp.'s (GMAC's) various bank facilities. GM's balance
sheet debt stood at about $32 billion at Dec. 31, 2005.

The need to attend to this issue adds to the various challenges that management
continues to face on a number of non-operating issues beyond solidifying access
to bank credit facilities, including the situation at Delphi Corp., the possible
sale of GMAC, and various accounting and other investigations.

GMAC ('BB/B-1') and all GMAC-related entities, including Residential Capital
Corp. (ResCap; 'BBB-/A-3') are already on CreditWatch with developing
implications, given GM's announced intention to sell a majority stake in GMAC.
The ratings on ResCap are two notches above GMAC's, its direct parent,
reflecting ResCap's ability to operate its mortgage businesses separately from
GMAC's auto finance business, from which ResCap is partially insulated by
financial covenants and governance provisions. However, we continue to link the
ratings on ResCap with those on GMAC because of the latter's full ownership of
ResCap.

Although the primary reason for GM's CreditWatch listing is GM's uncertain
access to existing or new bank facilities, the resolution of the CreditWatch
will also encompass other ongoing concerns, including the potential for work
stoppages at Delphi and possible costly resolution for GM, as well as our
primary concern--GM's North American operations. We will also consider progress
on the sale of a controlling stake in GMAC. We expect to resolve this review
once GM's access to existing or new bank facilities becomes more certain, or
sooner if other developments such as the Delphi situation warrant.

Previously, we indicated that if these financial reporting issues had any
near-term effect on GM's liquidity, the ratings could be placed on CreditWatch
with negative implications. We continue to view GM's unrestricted cash balances
as likely to be adequate, given a total of $20.4 billion at Dec. 31, 2005,
including available amounts in the short-term VEBA fund. We believe current cash
and VEBA balances remain close to year-end levels. Still, we are concerned that
GM is facing an incremental decrease in liquidity because of an uncertain period
of questionable access to its bank facility. This reduced liquidity is occurring
at the same time as various potential calls on liquidity are looming--for
example, probable upcoming resolution of issues at Delphi that could be costly
to GM. We expect GM to act to remedy these uncertainties, possibly by
establishing a new bank facility secured with certain assets as permitted under
existing indentures. Were a secured bank facility to be established, we would
review the effect of contractual subordination on the unsecured debt, and
depending on the level of security granted, the unsecured debt rating could be
lowered.

MOODY'S LOWERS GM RATING TO B3; GMAC AND RESCAP UNAFFECTED

Approximately $29 Billion of Debt Affected

New York, March 29, 2006 -- Moody's Investors Service lowered the ratings of
General Motors Corporation (GM) - Corporate Family Rating and senior unsecured
to B3 from B2 and Speculative Grade Liquidity Rating to SGL-3 from SGL-2. The
outlook is negative. GMAC and ResCap are unaffected -- see separate press
release. The GM rating actions come in response to the company's disclosure that
restatements of its 2002, 2003 and 2004 financial statements could result in the
acceleration of as much as $3 billion in various lease obligations and in the
company potentially not being be able to borrow under its $5.6 billion unused
revolving credit facility. Moody's said that although GM's $20.4 billion cash
and short-term VEBA position should afford the company adequate liquidity to
repay the affected lease obligations if necessary, this reduction in liquidity
increases the company's risk profile at a time when it faces considerable
ongoing operating and competitive challenges. These challenges include the need
to achieve an acceptable resolution to the Delphi reorganization, the continuing
financial pressure on its domestic supplier base, stemming the erosion in its US
market share position, effectively implementing its domestic restructuring
initiatives, establishing a business model that will reverse its large negative
automotive cash flow by the end of 2007, and completing the sale of a majority
interest in GMAC. The rating agency also expressed concern that the threat of a
possible acceleration of a large number of leases and the potential
unavailability of its credit facility could have negative implications for the
terms under which GM pays its trade creditors, with suppliers seeking earlier
payment. The downgrade of the Speculative Grade Liquidity rating to SGL-3 from
SGL-2 recognizes that one important component of GM's liquidity profile -- the
unused $5.6 billion credit facility -- may be unavailable.

The negative outlook recognizes the significant near-term operating challenges
that GM continues to face, the most significant of which is resolving the Delphi
reorganization and avoiding a protracted UAW strike at that supplier. Moody's
noted that the UAW rejected Delphi's most recent salary and benefit proposal,
and that the deadline set by Delphi for reaching an agreement with the union is
March 30th. Absent an agreement, Delphi has stated its intention to request
approval from the bankruptcy court to reject the current UAW contract. Court
approval of such a request could take 45-plus days. Moody's believes that the
risk of a UAW strike would increase as any potential court approval of
contract-rejection approaches.

One potential alternative available to GM for maintaining access to a credit
facility would be to grant collateral to its lenders. Moody's notes that the
limitation on liens provision of the indenture covering the company's
approximately $29 billion in public debt, would permit the granting of security
covering a significant portion of the automotive assets. The rating agency
cautioned, however, that the granting of such security could contribute to a
down-notching of the unsecured debt below the Corporate Family Rating level.

The GM rating action concludes a review for possible downgrade that was
initiated on March 16th when GM announced that the filing of its 2005 Form 10K
with the SEC would be delayed. At that time Moody's noted that its review would
focus on "the company's ability to file its financial statements in the near
term in order to avert potential disruption to its financial flexibility" and on
"on the quality of GM's 2005 earnings including an assessment of the impact of
restatements and disclosures relating to unusual charges as well as the extent
and nature, if any, of material weaknesses and control deficiencies." Although
filing of the 10K on March 28th was constructive, the rating agency believes
that the restatements have contributed to a potentially significant disruption
in GM's financial flexibility that warrants the one-notch downgrade to B3.

General Motors Corporation, headquartered in Detroit, Michigan, is the world's
largest producer of cars and light trucks.

MOODY'S MAINTAINS REVIEW OF GMAC AND RESCAP RATINGS

New York, March 29, 2006 -- Moody's Investors Service said today that it
maintained its review for possible downgrade on General Motors Acceptance
Corporation's Ba1 long-term rating and Residential Capital Corporation's
(ResCap) Baa3 long-term and Prime-3 short-term ratings. These actions follow the
announcement by the two firms and their parent, General Motors, that certain
prior period financial statements cannot be relied upon, as disclosed in
securities filings made by the firms yesterday. Concurrently, Moody's said it
downgraded GM's corporate family rating to B3 with a negative outlook.

Moody's believes that the further weakening at GM, as reflected in today's
rating downgrade, puts additional negative pressure on GMAC's stand-alone credit
profile. This is due to the substantial direct and indirect exposures GMAC
currently has to GM. However, Moody's maintained GMAC's Ba1 long-term rating, on
review for possible downgrade, because it believes that a successful conclusion
of the GMAC sale process could have positive implications for GMAC's current
stand-alone credit profile, corporate governance and control. This could lead to
the confirmation of GMAC's ratings at their current level.

In the absence of a sale transaction, Moody's said that it would re-link GMAC's
ratings with GM's ratings. This would most likely result in the assignment of a
Ba3 long-term rating to GMAC, absent the occurrence of additional deterioration
to its credit profile resulting from internal issues or further GM stress. In
addition, Moody's would monitor the structural subordination of GMAC's unsecured
creditors, and their potential loss given default, given the likely increased
reliance upon securitization financing in this scenario.

Moody's also stated that even if the sale of GMAC does not take place it would
most likely maintain the current Baa3 and Prime-3 ratings of ResCap. This rating
action would reflect Moody's expectation that ResCap would likely be sold on its
own if the GMAC sale efforts are abandoned. Moody's review of ResCap's ratings
is focusing on any further accounting or control issues, the company's continued
efforts to extinguish its intercompany debt with GMAC, and the progress made on
GM's sale of GMAC.

GMAC, a wholly-owned subsidiary of GM, provides retail and wholesale financing
in support of GM's automotive operations and is one of the world's largest
non-bank financial institutions.

ResCap is a holding company for the real estate financing businesses of GMAC,
including GMAC-RFC Holding and GMAC Residential Holding Corp.

MOODY'S LOWERS GM RATING TO B3; GMAC AND RESCAP UNAFFECTED

Approximately $29 Billion of Debt Affected

New York, March 29, 2006 -- Moody's Investors Service lowered the ratings of
General Motors Corporation (GM) - Corporate Family Rating and senior unsecured
to B3 from B2 and Speculative Grade Liquidity Rating to SGL-3 from SGL-2. The
outlook is negative. GMAC and ResCap are unaffected -- see separate press
release. The GM rating actions come in response to the company's disclosure that
restatements of its 2002, 2003 and 2004 financial statements could result in the
acceleration of as much as $3 billion in various lease obligations and in the

MOODY'S MAINTAINS REVIEW OF GMAC AND RESCAP RATINGS

New York, March 29, 2006 -- Moody's Investors Service said today that it
maintained its review for possible downgrade on General Motors Acceptance
Corporation's Ba1 long-term rating and Residential Capital Corporation's

ratings with GM's ratings. This would most likely result in the assignment of a
Ba3 long-term rating to GMAC, absent the occurrence of additional deterioration
to its credit profile resulting from internal issues or further GM stress. In
addition, Moody's would monitor the structural subordination of GMAC's unsecured
creditors, and their potential loss given default, given the likely increased
reliance upon securitization financing in this scenario.

Moody's also stated that even if the sale of GMAC does not take place it would
most likely maintain the current Baa3 and Prime-3 ratings of ResCap. This rating
action would reflect Moody's expectation that ResCap would likely be sold on its
own if the GMAC sale efforts are abandoned. Moody's review of ResCap's ratings
is focusing on any further accounting or control issues, the company's continued
efforts to extinguish its intercompany debt with GMAC, and the progress made on
GM's sale of GMAC.

GMAC, a wholly-owned subsidiary of GM, provides retail and wholesale financing
in support of GM's automotive operations and is one of the world's largest
non-bank financial institutions.

ResCap is a holding company for the real estate financing businesses of GMAC,
including GMAC-RFC Holding and GMAC Residential Holding Corp.
