                                EXPLANATORY NOTE

This Amendment No. 1 on Form 10-K/A amends the Annual Report on Form 10-K for
the year ended December 31, 2004, as initially filed by American General Finance
Corporation with the Securities and Exchange Commission (SEC) on March 7, 2005,
and is being filed solely to include the information that was properly excluded
from Form 10-K pursuant to General Instruction I of Form 10-K.

American General Finance Corporation will be referred to as "AGFC" or
collectively with its subsidiaries, whether directly or indirectly owned, as the
"Company" or "we". All of the common stock of AGFC is owned by American General
Finance, Inc. (AGFI). AGFI is an indirect wholly owned subsidiary of American
International Group, Inc. (AIG).

AIG has been unable to file its Annual Report on Form 10-K for the year ended
December 31, 2004 within the prescribed time period applicable to AIG. This Form
10-K/A does not alter or restate any of the information we reported in the Form
10-K filed on March 7, 2005. Instead, it adds the disclosures we had previously
omitted pursuant to General Instruction I of Form 10-K.

            parties to these agreements. The Severance Agreements provided for
            payment of certain benefits in the event of changes in terms or
            conditions of employment (including pay and benefits) within 3 years
            after the acquisition was completed. Certain payments were made to

            two-year period from January 1, 2003 to December 31, 2004 is set

      9)    Mr. Schiano is employed as the Chief Executive Officer of WFI, which
            we acquired in January, 2003. In connection with the acquisition,
            Mr. Schiano entered into an employment agreement with WFI. Under the
            agreement, Mr. Schiano receives a base salary of $300,000 per year,
            and may be eligible for an annual bonus, the payment and amount of
            which depend on WFI's actual pretax earnings compared to a specified
            profit target for each year as established by the Company from time
            to time. While the agreement has a five year term, it may be
            terminated by either party at any time for no reason; any severance
            payments to Mr. Schiano in the event of an early

                                       7
<PAGE>
            termination would be dependent on the reason for termination. If Mr.
            Schiano is terminated without cause, or resigns for good reason (as
            described in the agreement), he will be eligible to receive a
            severance payment consisting of monthly base salary plus benefits
            for a declining number of months (currently, 18 months) over the
            remaining term of the agreement.

</TABLE>

(1)      Awards represent grants of units under the SICO Plan with respect to
         the two-year period from January 1, 2003 through December 31, 2004. The
         SICO Plan contains neither threshold amounts nor maximum payout
         limitations. The number of shares of AIG Common Stock, if any,
         allocated to a unit for the benefit of a participant in the SICO Plan
         is primarily dependent upon two factors: the growth in future earnings
         of AIG during the unit award period and the book value of AIG at the
         end of the award period. As a result, the number of shares to be
         allocated with respect to units held for the 2003-2004 period and the
         value of such shares upon future payout cannot be determined at this
         time. The number of shares shown under "Estimated Future Payouts"
         represent the number of shares contingently allocable to the named
         individuals based upon the units awarded to them for the 2003-2004
         period, assuming the same criteria as those used to allocate the shares
         of AIG Common Stock for the 2001-2002 period. Prior to earning the
         right to payout, the participant is not entitled to any equity interest
         with respect to such shares, and the shares are subject to forfeiture
         under certain conditions, including but not limited to the
         participant's voluntary termination of employment with AIG or its
         subsidiaries prior to normal retirement age other than by death or
         disability.

The Company participates in several employee benefit plans sponsored by AIG.


                                PENSION BENEFITS

Prior to the purchase of American General Corporation (AGC) by AIG, the
Company's employees were covered by the American General Retirement Plan (AG
Plan). The AG Plan benefits were based on the employee's period of employment
with the Company and its subsidiaries (up to a maximum of 40 years of benefits
service). Benefits were calculated using average monthly compensation (including
all cash compensation except for certain excluded payments such as severance
payments, and subject to limitations for certain highly compensated employees
imposed by law) during the highest 5 consecutive calendar years of the last 10
years of employment, and covered compensation, using the average Social Security
taxable wage base over a 35-year period, ending when an employee attains Social
Security retirement age. The AG Plan benefit was frozen as of December 31, 2002.

Employees of the Company and its subsidiaries became eligible for the American
International Group, Inc. Retirement Plan (AIG Plan), effective January 1, 2003.
The AG Plan was merged into the AIG Plan. Employees were given both vesting and
benefit service credit for their prior service with the Company and its
subsidiaries.

The AIG Plan is a non-contributory, qualified, defined benefit plan. For
employees of the Company and its subsidiaries, the formula equals .925% times
Average Final Compensation (defined as the average annual compensation, which
includes base pay and sales commissions, subject to limitations for certain
highly compensated employees imposed by law, during the three consecutive years
in the last ten years of credited service affording the highest such average) up
to 150% of the employee's "covered compensation" (the average of the Social
Security Wage Bases during the 35 years preceding the Social Security retirement
age), plus 1.425% times Average Final Compensation in excess of 150% of "covered
compensation" times years of credited service (up to 35 years), plus 1.425%
times Average Final Compensation times years of credited service in excess of 35
years but limited to 44 years.

Employees of the Company and its subsidiaries will receive pension payments
based on the greater of (A) or (B). (A) is equal to (i) the AG Plan benefit
frozen as of December 31, 2002, plus (ii) a benefit reflecting service after
December 31, 2002 using the AIG Plan formula. (B) is equal to a benefit
determined using the AIG Plan formula reflecting service for employment with the
Company or its subsidiaries before and after AIG's acquisition of AGC.

AGC also had in place the American General Restoration of Retirement Income Plan
(AG Restoration Plan) for employees participating in the AG Plan whose benefits
under the AG Plan were limited by applicable tax laws. The AG Restoration Plan
provided benefits in excess of the AG Plan benefits determined as if the benefit
under the AG Plan had been calculated without the limitations imposed by
applicable tax laws. The AG Restoration Plan was a nonqualified, unfunded plan,
and was frozen as of December 31, 2002.

Certain employees also became eligible for payments under the AIG Excess
Retirement Income Plan (AIG Excess Plan), effective January 1, 2003. The AIG
Excess Plan was established to provide additional retirement benefits to
designated executives and key employees, and replaced the AG Restoration Plan.

In addition, certain officers are covered by the AGC Supplemental Executive
Retirement Agreement

(SERA) or the AGC Supplemental Executive Retirement Plan (SERP). The SERA and
SERP are non-qualified, unfunded, defined benefit pension plans or agreements
that provide for payment computed on the basis of a straight-life annuity with a
10-year term certain period, subject to certain offsets for payments under the
AIG Plan, the AG Restoration Plan, the AIG Excess Plan and Social Security
payments. Compensation used to calculate payments includes annual salary and
bonus amounts. The SERA and SERP benefit accruals continued in effect for 3
years after the acquisition of AGC by AIG, and benefits were frozen effective
August 31, 2004.

Annual amounts of normal retirement pension commencing at normal retirement age
of 65 based on average final compensation and credited service under the AIG
Plan, the AG Restoration Plan and the AIG Excess Plan are illustrated in the

The amounts shown in the table above reflect benefits calculated under the AIG
Plan, the AG Restoration Plan and the AIG Excess Plan assuming the benefits
described in (B) above (the AIG pension formula for all benefit service) result
in the greater benefit. The table does not reflect benefits payable under the
SERP or the SERA.

The years of benefit service under the pension plans as of December 31, 2004 are
as follows: Mr. Geissinger - -10.9 years; Mr. Loewenkamp - -39.8 years; Mr.
Roach- - 17.0 years; Mr. Hayes - -4.8 years. Base salaries used to calculate
benefits under the pension plans as of December 31, 2004 are as follows: Mr.
Geissinger - -$525,000; Mr. Loewenkamp - -$205,577; Mr. Roach- - $217,211; Mr.
Hayes - -$250,000.

Payments under the AGC plans have been "frozen" as of the dates noted above, and
as a result, projected payments for the four officers need to be determined on
an individual basis. Assuming a normal retirement age of 65, the following
officers would receive the annual pension payments noted: Mr. Geissinger -
$397,406 (payable as a 10-year certain and continuous annuity); Mr. Loewenkamp -
$117,523 (payable as a life annuity); Mr. Roach - $74,861 (payable as a life
annuity); and Mr. Hayes - $90,458 (payable as a 10-year certain and continuous
annuity);. As an employee of WFI, Mr. Schiano is not covered by the Company's
pension plan; WFI does not have a pension plan. Mr. Geissinger and Mr. Hayes
also have the option to select certain benefits as a lump sum.

Employees of the Company and its subsidiaries participate in the American
International Group, Inc. Incentive Savings Plan (Incentive Savings Plan), a
401(k) plan established by AIG which includes salary reduction contributions by
employees and matching contributions. Matching contributions vary based on the
number of years the employee has been employed. As an employee of WFI, Mr.
Schiano is not covered by the Incentive Savings Plan; WFI has a separate 401(k)
plan which similarly provides for salary reduction and

                                       12

matching contributions (the matching contributions are not based on years of
service).

The board of directors of the Company does not have a Compensation Committee.
Compensation decisions regarding the Chief Executive Officer are made by AIG.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

                             AIG AND ITS AFFILIATES

During 2004, we paid cash dividends to our stockholder aggregating $15 million
and received cash capital contributions from our stockholder in the amount of
$156 million. We are party to cost sharing arrangements with AIG which provide
for an allocation of corporate costs to the Company. The charges include, but
are not limited to, pension costs, certain senior management compensation and
costs of various corporate services. During 2004 the charges aggregated $15
million.

The counterparty to certain of our derivative financial instruments that relate
to long-term debt is an AIG subsidiary, AIG Financial Products Corp. (AIGFP).
During 2004, we executed the equivalent of $2.1 billion notional amount of
interest rate swap, foreign currency swap and equity-indexed swap transactions
with AIGFP. Additionally during 2004, we entered into and subsequently
terminated a short-term Treasury rate lock agreement with AIGFP with a notional
amount of $300 million. All of these transactions with AIGFP were executed in
connection with the Company's issuances of long-term debt in the capital markets
and were on arms-length bases.

We join in the filing of a consolidated U.S. Federal income tax return with AIG
and its eligible domestic subsidiaries. We are a party to a written agreement
(the "Tax Sharing Agreement") with AIG setting forth the manner in which the
total consolidated U.S. Federal income tax is allocated to each entity that
joins in the consolidated return. The Tax Sharing Agreement provides that AIG
agrees not to charge us a greater portion of the consolidated tax liability than
would have been paid by us had we filed a separate federal income tax return.
Additionally, AIG agrees to reimburse us for any tax benefits arising out of net
losses or tax credits, if any, within ninety days after the filing of the
consolidated federal income tax return for the year in which such losses or tax
credits are utilized by AIG.

Certain of our subsidiaries have agreements with AIG Federal Savings Bank (AIG
Bank), a non-subsidiary affiliate, in two businesses. First, we purchase and
service private label receivables originated by AIG Bank pursuant to a
participation agreement. Private label receivables are open end accounts that
account holders can use for financing repeated purchases from the same merchant.
Second, our mortgage origination subsidiaries have entered into agreements with
AIG Bank whereby these subsidiaries provide marketing, certain mortgage
origination processing services, loan servicing, and related services for AIG
Bank's origination and sale of non-conforming residential real estate loans. Our
subsidiaries regularly purchase a portion of the mortgages so originated. Fees
paid pursuant to these agreements are based on arms-length market price for the
services. Each of AIG Bank on the one hand and the Company's subsidiaries on the
other hand receives compensation in the aforementioned agreements. The Company's
2004 revenues include an aggregate net amount of $196.8 million as compensation
received from AIG Bank for services rendered or activities undertaken by the
Company's private label and mortgage operations.

                                      OTHER

In 2002, the Company entered into an agreement to purchase all of the stock of
WFI which transaction was consummated effective January 1, 2003. Mr. Schiano,
the founder and Chief Executive Officer of WFI, was a holder of approximately
19% of the shares of WFI, and was one of the selling shareholders. The purchase
price was $121 million, part of which was


                                       15
<PAGE>
deferred as to the individual selling shareholders who were part of management.
The purchase price was determined based on arms-length negotiations between the
management of the Company and the sellers and was approved by the board of
directors of the Company. Deferred payments, which are scheduled to be made
annually over a five (5) year period, are contingent on the continued employment
by WFI of the individual selling shareholders. The payment by the Company to Mr.
Schiano which is attributable to 2004 under the agreement was $2.08 million.
Assuming Mr. Schiano continues to meet the contingency described above, the
Company will be required to pay approximately $2.83 million in the aggregate to
Mr. Schiano in the future under the agreement.
