1. This registration statement also relates to an indeterminate number of additional shares of Common Stock that may be issued pursuant to anti-dilution and adjustment provisions of the above-referenced plan. 2. Estimated solely for purposes of calculating the registration fee. This estimate has been computed in accordance with Rule 457(c) and (h)(1) and is calculated based upon the average of the high and low sales prices of the Common Stock of American International Group, Inc. on May 20, 2004, as reported on the New York Stock Exchange Composite Tape. ================================================================================ PART I INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS All information required by Part I to be contained in the prospectus is omitted from this registration statement in accordance with Rule 428 under the Securities Act of 1933, as amended (the "Securities Act"). PART II INFORMATION REQUIRED IN THE REGISTRATION STATEMENT ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE The following documents have been filed by American International Group, Inc., ("AIG") with the Securities and Exchange Commission (the "Commission") (File No. 1-8787) and are incorporated herein by reference: (a) AIG's Annual Report on Form 10-K for the year ended December 31, 2003; (b) AIG's Quarterly Report on Form 10-Q for the quarter ended March 31, 2004; and (c) The description of Common Stock contained in the registration statement on Form 8-A, dated September 20, 1984, filed pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). All documents filed by AIG after the date hereof pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, prior to the filing of a post-effective amendment which indicates that all securities offered have been sold, or which deregisters all such securities then remaining unsold, shall be deemed to be incorporated by reference in this registration statement and to be a part hereof from the date of filing of such documents. Any statement contained in a document incorporated by reference herein shall be deemed to be modified or superseded for purposes of this registration statement to the extent that a statement contained herein or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or supersedes such statement. Any such statement so modified or superseded will not be deemed, except as so modified or superseded, to constitute a part of this registration statement. ITEM 4. DESCRIPTION OF SECURITIES The Common Stock is registered under Section 12(b) of the Exchange Act. ITEM 5. INTEREST OF NAMED EXPERTS AND COUNSEL The consolidated financial statements of AIG and its subsidiaries and the related financial statement schedules of AIG included in its Annual Report on Form 10-K for the year ended December 31, 2003, incorporated herein by reference, are so incorporated in reliance upon the report of PricewaterhouseCoopers LLP, an independent registered public accounting firm, given on the authority of that firm as experts in accounting and auditing. The validity of the shares of Common Stock offered pursuant to the American International Group, Inc. Director Stock Plan (the "Plan") will be passed upon by Kathleen E. Shannon, Esq., Senior Vice President 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 Common Stock and currently beneficially owns less than 1% of the outstanding shares of Common Stock. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS The restated certificate of incorporation of AIG, as amended, provides that AIG shall indemnify to the full extent permitted by law any person made, or threatened to be made, a party to an action, suit or II-1 proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she, his or her testator or intestate is or was a director, officer or employee of AIG or serves or served any other enterprise at the request of AIG. Section 6.4 of AIG's by-laws contains a similar provision. The restated certificate of incorporation, as amended, also provides that a director will not be personally liable to AIG or its shareholders for monetary damages for breach of fiduciary duty as a director, except to the extent that the exemption from liability or limitation thereof is not permitted by the Delaware General Corporation Law. Section 145 of the Delaware General Corporation Law permits indemnification against expenses, fines, judgments and settlements incurred by any director, officer or employee of a company in the event of pending or threatened civil, criminal, administrative or investigative proceedings, if such person was, or was threatened to be made, a party by reason of the fact that he or she is or was a director, officer or employee of the company. Section 145 also provides that the indemnification provided for therein shall not be deemed exclusive of any other rights to which those seeking indemnification may otherwise be entitled. In addition, AIG and its subsidiaries maintain a directors' and officers' liability insurance policy. ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED Not applicable. ITEM 8. EXHIBITS The exhibits are listed in the exhibit index. ITEM 9. UNDERTAKINGS AIG hereby undertakes: (a) (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933 as amended; (ii) To reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement; provided, however, that paragraphs (a) (1)(i) and (a) (1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by AIG pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. II-2 (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) That, for purposes of determining any liability under the Securities Act of 1933, each filing of AIG's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of AIG pursuant to the foregoing provisions, or otherwise, AIG has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by AIG of expenses incurred or paid by a director, officer or controlling person of AIG in the successful defense of any action, suit or proceeding) is asserted against AIG by such director, officer or controlling person in connection with the securities being registered, AIG will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of New York, State of New York, on this 26th day of May, 2004.

American International Group, Inc.
70 Pine Street
New York, New York 10270

Ladies and Gentlemen:

      In connection with the registration under the Securities Act of 1933, as
amended (the "Act"), of 100,000 shares (the "Securities") of Common Stock, par
value $2.50 per share (the "Common Stock"), of American International Group,
Inc., a Delaware corporation (the "Company"), I, as Senior Vice President and
Deputy General Counsel of the Company, have examined such corporate records,
certificates and other documents, and such questions of law, as I have
considered necessary or appropriate for the purposes of this opinion.

      Upon the basis of such examination, I advise you that, in my opinion, with
respect the Securities to be acquired under the American International Group,
Inc. Director Stock Plan (the "Plan"), when the registration statement relating
to the Securities (the "Registration Statement") has become effective under the
Act and the Securities are duly issued and delivered in accordance with the
terms of the Plan, the Securities will be validly issued, fully paid and
non-assessable.

      The foregoing opinion is limited to the Federal laws of the United States
and the General Corporation Law of the State of Delaware, and I am expressing no
opinion as to the effect of the laws of any other jurisdiction.

      With your approval, I have relied as to certain matters on information
obtained from public officials, officers of the Company and other sources
believed by me to be responsible, and I have assumed that the certificates for
the Securities will conform to the specimen thereof examined by me and will be
duly countersigned by a transfer agent and duly registered by a registrar of the
Common Stock, and that the signatures on all documents examined by me are
genuine, assumptions that I have not independently verified.

      I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. In giving such consent, I do not thereby admit that I am
in the category of persons whose consent is required under Section 7 of the Act.

                                   Very truly yours,


                                   /s/ Kathleen E. Shannon

                                   Deputy General Counsel


                                                                   EXHIBIT 23(a)

            CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

      We hereby consent to the incorporation by reference in this Registration
Statement on Form S-8 of our report dated February 11, 2004 relating to the
consolidated financial statements and financial statement schedules of American
