Deferred Compensation Obligations

of

SAI DEFERRED COMPENSATION HOLDINGS, INC.

unconditionally

guaranteed as to payment by

AMERICAN INTERNATIONAL GROUP, INC.

       Under the Amended and Restated Registered Representative’s Deferred Compensation Plan, you may defer receipt of all or a portion of your commissions and other advisory fees. While deferred, these commissions and fees are treated as if they were invested in the valuation funds selected by you. However, you have no direct interest in any of these valuation funds.

      SAI Deferred Compensation Holdings, Inc. (“SAI Holdings”) is obligated to repay your deferred compensation in accordance with the plan, and American International Group, Inc. (“AIG”) has fully and unconditionally guaranteed SAI Holdings’s payment obligation. The obligations of SAI Holdings and AIG under the plan and the guarantee, respectively, are not secured and represent general obligations of SAI Holdings and AIG.

      Neither SAI Holdings nor AIG will receive any proceeds from the issuance of the deferred compensation obligations or the guarantee.

       See “Risk Factors” on page 2 for certain information that you should consider before participating in the plan.

       Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus is November 30, 2006.

RISK FACTORS

      A decision to participate in the Amended and Restated Registered Representatives’ Deferred Compensation Plan (referred to as the plan) involves certain risks. You should carefully consider the following information, as well as the other information included or incorporated by reference in this prospectus, in considering whether to participate in the plan.

      The value of your deferred compensation is indexed to the performance of the valuation funds selected by you. The valuation funds may go up or down in value, and the value of your deferred compensation will correspondingly increase or decrease. As a result, you may lose your entire investment in the plan.

      Although you may decrease your deferred election to zero, this will not eliminate your market risk with respect to amounts previously deferred. Accordingly, the amount of compensation that you have already deferred will continue to increase or decrease corresponding to your valuation fund selections until your accounts are paid out in full.

      Your accounts may not be paid out for an extended period of time, as described under “Description of Deferred Compensation Obligations — Payment of Earnings.” Other than with respect to interest the plan does not guarantee a minimum rate of return. For a description of interest paid on your deferred earnings, see “Description of Deferred Compensation Obligations — Interest.”

      You may index your deferred compensation to a number of valuation funds as described under “Description of Deferred Compensation Obligations — The Deferred Earnings.” Neither AIG nor SAI Holdings makes any recommendation as to which valuation funds you should select or how much deferred compensation you should index to any particular valuation fund. You must do your own analysis of the risks and benefits of selecting a particular valuation fund. You also must determine which valuation funds are a suitable investment for you based on your investment and other objectives. You are encouraged to carefully review the prospectus relating to each valuation fund that you select. You may select a valuation fund that is inappropriate for your investment objectives and you may lose, or not maximize the return on, your deferred compensation.

      Your deferred compensation is indexed to the value of the valuation funds selected by you. Your deferred compensation is not invested in the funds by SAI Holdings or AIG on your behalf. Your sole recourse for repayment under the plan is to SAI Holdings, as the issuer of the plan, and AIG as the guarantor. Your ability to receive your deferred compensation depends entirely on whether SAI Holdings or AIG has the funds to pay you on the designated payment date.

      The plan does not require AIG or SAI Holdings to hedge their exposure under the plan by purchasing interests in the valuation funds. However, AIG and SAI Holdings may hedge their exposure under the plan through purchasing or selling interests in the underlying valuation funds, or purchasing or selling derivative or other instruments relating to the funds. You do not have any interest in the profits or losses arising from these hedging activities, and AIG or SAI Holdings may profit from these activities while the value of your deferred compensation may decline. These activities may adversely affect the value of the underlying valuation funds.

DESCRIPTION OF DEFERRED COMPENSATION OBLIGATIONS

Purpose of Plan

      In connection with the acquisition of SunAmerica Inc. by AIG, SAI Holdings has assumed SunAmerica’s obligations under the plan. AIG has guaranteed SAI Holdings’s payment obligations.

      The purpose of the plan is to:

Participation

      Your enrollment in the plan is voluntary. You will be eligible to participate in the plan on the first day of any month after you have been licensed with any of the broker/dealer subsidiaries listed in the box below or any additional broker/dealer subsidiaries added to the plan by SAI Holdings for three full months. Earlier

participation may be permitted by the President of the relevant broker/dealer subsidiary. Once you become eligible to participate, you will remain eligible to participate in the plan until it is amended or, in the case of any particular enrollment period, until the occurrence of a termination event.

      So long as you are eligible to participate in the plan, you may re-enroll in the plan after the occurrence of a termination event with respect to a particular enrollment period. If you re-enroll in the plan, SAI Holdings will establish and maintain a distinct and separate account, comprised of a fund account and an interest account, for you for each enrollment period. Each new account established under the plan will be treated in the same manner as all previously established accounts.

                                           Eligible Broker/Dealer Subsidiaries of AIG 

• Advantage Capital Corporation

• Royal Alliance Associates Inc.

• SunAmerica Securities, Inc.

• FSC Securities Corporation

• Spelman & Co., Inc.

• Sentra Securities Corporation

The Deferred Earnings

      Under the plan, for each enrollment period, you will be offered an opportunity to enter into an agreement for the deferral of a percentage of your fees and commissions by your broker/dealer subsidiary. For each enrollment period, you will execute a deferred compensation agreement and an enrollment/change form which will set forth your obligations and SAI Holdings’s obligations under the plan.

      SAI Holdings’ obligations to make payments under the plan will not be secured by any of SAI Holdings’s property or assets. Accordingly, if you participate in the plan you will be one of SAI Holdings’s unsecured creditors. SAI Holdings’s obligation to make payments under the plan will rank equally with all other unsecured and unsubordinated indebtedness of SAI Holdings.

      Holders of secured obligations of SAI Holdings will, however, have claims that are prior to your claims under the plan with respect to the assets securing those other obligations.

      For each enrollment period, you may elect to defer from 1% to 100% of your fees and commissions. You may make changes to the amount of your earnings to be deferred for each enrollment period. The change will not take effect until the beginning of the next calendar year and must remain in effect for one full calendar year.

      For each enrollment period, two deferral accounts will be created for you. The fund account will be for the purpose of determining the value of your deferred earnings with respect to such enrollment period. The interest account will be for the purpose of keeping track of the interest earned on your deferred earnings with respect to such enrollment period. Your deferred earnings with respect to each enrollment period will be credited to your accounts within three business days of the date the earnings otherwise would have been paid.

      Earnings in the fund account with respect to each enrollment period will be indexed to one or more investment options selected by you from a list of available valuation funds. The value of each of your fund accounts will be adjusted to reflect the investment experience of the valuation funds selected by you, and you will receive a statement of your accounts on a semi-annual basis. The fund account with respect to each enrollment period will be adjusted for both positive and negative investment experience. You may change the valuation funds used to measure the value of your fund account with respect to an enrollment period once per business day. Because the value of the fund account and therefore the deferred earnings will vary with the investment experience of the valuation funds selected by you, participation in the plan entails investment risk which will be

borne solely by you. Neither AIG nor SAI Holdings makes any representation as to the investment performance of any valuation fund.

      You may choose one or more than one of the following retail mutual funds and investment portfolios as an index for your deferred earnings:

      Each valuation fund’s investment objective is stated below:

      SAI Holdings reserves the right to terminate the availability of any valuation fund and add additional valuation funds at any time.

      You do not have any right, title or interest in or to any funds in the accounts. All funds in the accounts are funds of SAI Holdings.

      You may not sell, transfer, assign, pledge or encumber your interest in the plan, except by the laws of descent and distribution, but you may assign your interest in the plan to a revocable living trust set up by you. In general, a revocable living trust is a trust created by an individual in the individual’s lifetime to hold some or all of the individual’s assets. The trust may be revoked by the individual at any time. If the trust is not revoked, it controls the disposition of the trust assets at the individual’s death.

      The obligation of SAI Holdings to pay you the value of your accounts is not convertible into any other security of SAI Holdings or AIG. The plan does not contain any restriction on the business of SAI Holdings or AIG. Neither the plan nor the guarantee contains any provision limiting or preventing AIG from entering into a merger, consolidation or other business combination or effecting a restructuring.

Interest

      The amount of your initially deferred earnings will bear interest at 2.75% per annum. SAI Holdings reserves the right to change the interest rate from time to time. Interest will accrue on the initial amount of deferred earnings with respect to each enrollment period and not on the value of your fund account with respect to such enrollment period. Interest will be calculated on the basis of a year of twelve-30 day months.

      The amounts payable under your interest account with respect to each enrollment period may be subtracted from the amounts payable under your fund account with respect to such enrollment period as discussed below under “Payment of Earnings.”

Payment of Earnings

      Your accounts with respect to each enrollment period are not subject to redemption, in whole or in part, prior to the payment date selected by you with respect to such enrollment period, except upon the occurrence of any of the following:

      In any of these termination events, your accounts will be valued for lump sum payment or the first installment payment on the last business day that the U.S. financial markets are open of the calendar month at least thirty days after the occurrence of one of these termination events, except that:

      You will receive your initial payment within 60 days of your accounts being valued.

      Your accounts will be valued for installment payments other than the initial payment on the last business day that the U.S. financial markets are open of the year preceding the payment.

      Other than the initial payment, you will receive your installment payments within the first four weeks of each calendar year in which you are due to receive a payment.

      Your accounts with respect to each enrollment period will be paid out in ten annual installments unless you select an optional distribution date for such enrollment period. You may select an optional distribution date for a particular enrollment period either at the time of the commencement of that enrollment period or prior to December 31 of any year. If an optional distribution date is selected other than at the time of the commencement of an enrollment period, the optional distribution date will become effective on the immediately succeeding January 1. No such optional distribution date may be earlier than the first day of the calendar quarter that is at least four years after the commencement of the enrollment period. A previously selected optional distribution date may be changed by completing the required paperwork by December 31 of any year; provided, however, that such change must occur before January 1 of the year before the year in which the current optional distribution date for that enrollment period falls. For example, if a payment date is due in July of 2008, you must elect to change that date by December 31, 2006.

      Your accounts will be paid out in a lump sum if any of the following occurs:

      In each of these events you will be paid within 60 days of your accounts being valued.

      You may designate a beneficiary to receive distributions from your accounts in the event of your death.

      The amount to be paid under the plan on any payment date with respect to a particular enrollment period will equal the sum of:

      plus

      less

      The basic effect of this equation is to ensure a minimum rate of return on any initially deferred compensation after January 1, 1999. If your fund account with respect to a particular enrollment period has not appreciated, then AIG or SAI Holdings will supply the funds for your guaranteed return represented by the amount in the interest account with respect to such enrollment period. If your fund account with respect to such enrollment period has appreciated, then you will only receive that appreciation which exceeds the minimum return, in addition to the amount in your interest account with respect to such enrollment period.

Taxes and Withholdings

      Any payment under the plan will be subject to withholding of all applicable taxes. If SAI Holdings or AIG should become obligated to make a tax payment with respect to your account, SAI Holdings and AIG will have the right to pay on your behalf.

      SAI Holdings and AIG will have the right to deduct any obligation of yours owing to them or any broker/ dealer subsidiary from amounts owing to you under the plan.

Amendment and Termination

      SAI Holdings may amend or terminate the plan at any time, with or without notice. However, no amendment or termination may reduce the amounts credited to your accounts. Upon termination of the plan, your accounts will be paid out in a manner specified by the management committee administering the plan.

Administration

      A management committee will be created to administer the plan. The committee will be comprised of any five officers of AIG or any subsidiary of AIG as selected by any of the following:

      The committee will interpret and administer the plan and the agreements. The committee’s interpretations and constructions of the plan and the agreements will be binding and conclusive on you, SAI Holdings and AIG.

DESCRIPTION OF GUARANTEE

      The deferred compensation obligations of SAI Holdings will be guaranteed by AIG. If SAI Holdings does not pay your deferred compensation, AIG is obligated to pay your deferred compensation. AIG’s guarantee is full and unconditional which means that there are no circumstances under which SAI Holdings would be required, but AIG would not be required, to pay you and there are no conditions to AIG’s payment obligation beyond SAI Holdings’s failure to pay.

      AIG’s obligations to make payments under the guarantee will not be secured by any of AIG’s property or assets. Accordingly, you will be one of AIG’s unsecured creditors. AIG’s obligations under the guarantee will rank equally with all other unsecured and unsubordinated indebtedness of AIG.

      Holders of secured obligations of AIG will, however, have claims that are prior to your claims under the guarantee with respect to the assets securing those other obligations.

      You may enforce AIG’s obligation directly against AIG, and AIG waives any right or remedy to require that any action be brought against SAI Holdings or any other person or entity before proceeding against AIG. AIG’s obligation will not be discharged except by payment of the guarantee in full.

      Under the guarantee, upon AIG’s payment of all of the deferred compensation obligations owing to you, AIG shall be substituted in your place as a creditor of SAI Holdings. The guarantee provides that you will agree to take steps to meet reasonable requests by AIG to implement its rights as a creditor.

      The guarantee does not include any covenant or restriction on the business of AIG. In particular, the guarantee does not contain any provision that limits or prevents AIG from entering into a merger, consolidation or other business combination or to effect a restructuring.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

      This section describes the material federal income tax consequences of participating in the plan and is the opinion of Sullivan & Cromwell LLP, counsel to SAI Holdings. This section is based on the Internal Revenue Code of 1986, as amended, its legislative history, existing and proposed regulations under the Internal Revenue Code, published rulings and court decisions, all as currently in effect. These laws are subject to change, possibly on a retroactive basis. You may also be subject to foreign, state, local and other taxes, the consequences of which are not discussed here, in the jurisdiction in which you work and/or reside. Please consult your own tax advisor concerning the federal, state, local and other tax consequences of participating in the plan in light of your particular circumstances.

      You should not be subject to federal income tax at the time you defer earnings under the plan, and you should not be subject to tax on any amounts credited to your plan accounts until those amounts are distributed or otherwise made available to you. You should realize taxable compensation income in an amount equal to any amount distributed to you, including any appreciation in your fund account, and you should be subject to self-employment taxes on the amounts distributed to you. The payout schedule elected by you may affect the aggregate amount of taxes (including self-employment taxes) payable on the distributed amounts. You should consult with our own tax advisor as to the effect of selecting a particular payout schedule. See “Description of Deferred Compensation Obligations — Payment of Earnings.” SAI Holdings generally should be entitled to a tax deduction for any amounts distributed under the plan at the time of distribution.

      You should be aware that your deferrals under the plan may be subject to new Section 409A of the Internal Revenue Code, which generally governs the taxation of non-qualified deferred compensation. Failure to comply with Section 409A could subject you to additional tax and interest. Final regulations have not yet been promulgated under new Section 409A. Pending the issuance of final regulations or other applicable guidance, SAI Holdings has relied (in 2005 and 2006) upon a reasonable and good faith interpretation that Section 409A does not apply to the plan under the standards set forth in Internal Revenue Service Notice 2005-1, Q&A-8 (2005-2 I.R.B. 274) with respect to independent contractors. However, if it is ultimately determined that the plan is subject to Section 409A of the Internal Revenue Code, certain provisions of the plan will need to be amended and may need to be modified in practice in advance of such amendments.

PLAN OF DISTRIBUTION

      The deferred compensation obligations and related guarantee will be offered by each broker/dealer subsidiary of AIG listed under “Description of Deferred Compensation Obligations — Participation” to its eligible employees. No agents, underwriters or dealers will be used in connection with such offering.

VALIDITY OF THE SECURITIES

      The validity of the deferred compensation obligations will be passed upon for SAI Holdings by Sullivan & Cromwell LLP, Los Angeles, California. Partners of Sullivan & Cromwell LLP involved in the representation of AIG beneficially own approximately 11,360 shares of AIG common stock. The validity of the guarantee will be passed upon by Kathleen E. Shannon, Esq., Senior Vice President, Secretary and Deputy General Counsel of AIG. Ms. Shannon is regularly employed by AIG, participates in various AIG employee benefit plans under which she may receive shares of AIG common stock and currently beneficially owns less than 1% of the outstanding shares of AIG common stock.

EXPERTS

CAUTIONARY STATEMENT REGARDING PROJECTIONS AND OTHER INFORMATION ABOUT FUTURE EVENTS

      This prospectus and the documents incorporated herein by reference, as well as other publicly available documents, may include, and AIG’s officers and representatives may from time to time make, projections concerning financial information and statements concerning future economic performance and events, plans and objectives relating to management, operations, products and services, and assumptions underlying these projections and statements. These projections and statements are not historical facts but instead represent only AIG’s belief regarding future events, many of which, by their nature, are inherently uncertain and outside AIG’s control. These projections and statements may address, among other things, the status and potential future outcome of the current regulatory and civil proceedings against AIG and their potential effect on AIG’s businesses, financial position, results of operations, cash flows and liquidity, the effect of the credit rating downgrades on AIG’s businesses and competitive position, the unwinding and resolving of various relationships between AIG and C.V. Starr & Co., Inc. and Starr International Company, Inc. and AIG’s strategy for growth, product development, market position, financial results and reserves. It is possible that AIG’s actual results and financial condition may differ, possibly materially, from the anticipated results and financial condition indicated in these projections and statements. Factors that could cause AIG’s actual results to differ, possibly materially, from those in the specific projections and statements are discussed throughout Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 7, Part II, of AIG’s Annual Report on Form 10-K/A for the fiscal year ended December 31, 2005 and Risk Factors in Item 1A., Part I of AIG’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005 and in AIG’s Quarterly Reports on Form 10-Q for the quarterly periods ended September 30, 2006, June 30, 2006, and March 31, 2006.
