Item  2.06  Material Impairments

On January 11, 2006, management recommended, and the Management Audit Committee
of General Motors Acceptance Corporation (GMAC) approved, non-cash goodwill
impairment charges of approximately $450 million (after-tax), which will be
recorded in the quarter ended December 31, 2005. The charges relate
predominantly to GMAC's Commercial Finance operating segment and, in particular,
primarily to the goodwill recognized in connection with the 1999 acquisition of 
The Bank of New York's commercial finance business.

These fourth quarter charges result from annual impairment tests required to be
made for all of GMAC's reporting units in accordance with Statement of Financial
Accounting Standards No. 142, "Goodwill and Other Intangible Assets" (SFAS 142).
Management's conclusions were reached as part of the year-end preparation of
financial statements required to be included in GMAC's Annual Report on Form
10-K to be filed with the Securities and Exchange Commission in mid-March. The
audit of such financial statements by the Company's external auditors remains in
process.

GMAC will report fourth quarter and full year 2005 earnings on January 26, 2006.
Net income for the year is expected to be relatively consistent with previously
announced expectations - in the $2.5 billion range - after considering these
impairment charges, and well in excess of such guidance, excluding these
impairment charges.
