          2006 Regulatory Settlements

          In February 2006, AIG reached a final settlement with the Securities
and Exchange Commission ("SEC"), the United States Department of Justice
("DOJ"), the Office of the New York Attorney General ("NYAG") and the New York
State Department of Insurance ("DOI"). The settlements resolved outstanding
litigation filed by the SEC, NYAG and DOI against AIG and concluded negotiations
with these authorities and the DOJ in connection with the accounting, financial
reporting and insurance brokerage practices of AIG and its subsidiaries, as well
as claims relating to the underpayment of certain workers compensation premium
taxes and other assessments.

          AIG, without admitting or denying the allegations in the SEC
complaint, consented to the issuance of a final judgment on February 9, 2006:
(a) permanently restraining and enjoining AIG from violating Section 17(a) of
the Securities Act of 1933, as amended ("Securities Act"), and Sections 10(b),
13(a), 13(b)(2) and 13(b)(5) and Rules 10b-5, 12b-20, 13a-1, 13a-13 and 13b2-1
of the Securities Exchange Act of 1934, as amended ("Exchange Act"); (b)
ordering AIG to pay disgorgement in the amount of $700 million; and (c) ordering
AIG to pay a civil penalty in the amount of $100 million. These amounts have
been paid into a fund under the supervision of the SEC to be available to
resolve claims asserted in various civil proceedings, including shareholder
lawsuits.

          In February 2006, AIG and the DOJ entered into a letter agreement. In
the letter agreement, the DOJ notified AIG that in its view, AIG, acting through
some of its employees, violated federal criminal law in connection with
misstatements in periodic financial reports that AIG filed with the SEC between
2000 and 2004 relating to certain transactions. The settlement with the DOJ
consists of, among other things, AIG's cooperating with the DOJ in the DOJ's
ongoing criminal investigation, accepting responsibility for certain of its
actions and those of its employees relating to these transactions and paying $25
million.

          Effective February 9, 2006, AIG entered into agreements with the NYAG
and the DOI, settling claims under New York's Martin Act and insurance laws,
among other provisions, which were originally brought by the NYAG and the DOI in
a civil complaint filed on May 26, 2005. Under the agreements, $375 million was
paid into a fund under the supervision of the NYAG and the DOI to be available
principally to pay certain AIG insureds who purchased excess casualty policies
through Marsh & McLennan Companies, Inc. or Marsh Inc. In addition,
approximately $343 million will be used to compensate participating state funds
in connection with the underpayment of certain workers compensation premium
taxes and other assessments. In addition, AIG paid $100 million as a fine to the
State of New York.

          As part of these settlements, AIG has agreed to retain for a period of
three years an independent consultant who will conduct a review that will
include the adequacy of AIG's internal controls over financial reporting and the
remediation plan that AIG has implemented as a result of its own internal
review.

          PNC Settlement

          In November 2004, AIG and AIG Financial Products Corp. ("AIGFP"), a
subsidiary of AIG, reached a final settlement with the SEC, the Fraud Section of
the DOJ and the United States Attorney for the Southern District of Indiana with
respect to issues arising from certain structured transactions entered into with
Brightpoint, Inc. and The PNC Financial Services Group, Inc. ("PNC"), the
marketing of transactions similar to the PNC transactions and related matters.


                                      -3-


          AIG, without admitting or denying the allegations in the SEC
complaint, consented to the issuance of a final judgment permanently enjoining
it and its employees and related persons from violating certain provisions of
the Exchange Act, Exchange Act Rules and the Securities Act, ordering
disgorgement of fees it received from the PNC transactions and providing for AIG
to establish a transaction review committee to review the appropriateness of
certain future transactions and to retain an independent consultant to examine
certain transactions entered into between 2000 and 2004 and review the policies
and procedures of the transaction review committee.

          The settlement with the DOJ consists of separate agreements with AIG
and AIGFP and a complaint filed against, and deferred prosecution agreement
with, AIGFP PAGIC Equity Holding Corp. ("AIGFP PAGIC"), a wholly-owned
subsidiary of AIGFP. Under the terms of the settlement, AIGFP paid a monetary
penalty of $80 million. On January 17, 2006, the court approved an order
dismissing the complaint with prejudice. The obligations of AIG, AIGFP and AIGFP
PAGIC under the DOJ agreements relate principally to cooperating with the DOJ
and other federal agencies in connection with their related investigations.

     Item 4. Purpose of Transaction.

          Item 4 is hereby amended to add the following:

          On April 19, 2006, AIG informed the Company that it intends to
exercise its demand registration rights to register for sale up to 15.397
million of the Common Shares it owns in a public offering, subject to market
conditions. AIG also informed the Company that it intends to continue to provide
the Company with investment management, administrative and other services and
that Mr. S. George Cubbon, President and Chief Executive Officer of American
International Company, Ltd., intends to remain on the Company's Board of
Directors.


                                      -4-


          The manner, timing and execution of any sale of any or all of the
Common Shares would be in AIG's discretion and subject to market conditions and
may not occur. Notwithstanding the foregoing, AIG may determine to change its
investment intent with respect to the Company at any time in the future. In
reaching any conclusion as to its future course of action, AIG may take into
consideration various factors, such as the Company's business and prospects,
other developments concerning the Company, other business opportunities
available to AIG, developments with respect to the business of AIG, and general
economic and stock market conditions, including, but not limited to, the market
price of the Common Shares and of its own stock. AIG reserves the right, based
on all relevant factors, to acquire additional Common Shares in the open market
or in privately negotiated transactions, to dispose of all or a portion of its
holdings of Common Shares, or to change its intention with respect to any or all
of the matters referred to in this Item.

          On April 19, the Company issued a press release announcing AIG's
intent to exercise its demand registration rights. A copy of that press release
is filed herewith as Exhibit B and incorporated herein by reference.
