            This Amendment No. 3 to Schedule 13D amends the Schedule 13D as
follows.


ITEM 3.   SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

            The total amount of funds that will be required by the Investors to
purchase the Common Shares and Preference Shares as described under Item 4 below

ITEM 4.     PURPOSES OF THE TRANSACTION.

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the
following:

            On February 28, 2003, the Investors entered into a letter agreement
(the "Letter Agreement") with Trident II, L.P., Marsh & McLennan Capital
Professionals Fund, L.P., Marsh & McLennan Employees' Securities Company, L.P.
and Marsh & McLennan Risk Capital Holdings Ltd. (collectively, the "Sellers")
pursuant to which the Investors agreed to purchase from the Sellers, and the
Sellers agreed to sell to the Investors, an aggregate of 1,131,065 Preference
Shares and 488,935 Common Shares, for aggregate consideration of $50,220,000.
The transaction contemplated by the Letter Agreement is scheduled to be
completed on March 20, 2003.

ITEM 5.     INTEREST IN SECURITIES OF THE ISSUER.

Item 5 of the Schedule 13D is hereby amended and supplemented by adding the
following:



-----------------------                                   ---------------------
 CUSIP No. 011576290             SCHEDULE 13D/A            Page 9 of 12 Pages
-----------------------                                   ---------------------

(a)  The Reporting Persons beneficially own Common Shares of the Company by
     virtue of their ownership of an aggregate of 1,605,912 Common Shares (which
     include an aggregate of 3,688 Common Shares issued to John L. Bunce, Jr.
     and David Tunnell, each of whom is an affiliate of the Reporting Persons,
     in consideration of their service as directors of the Company, which Common
     Shares are held for the benefit of the Reporting Persons), of an aggregate
     of 12,745,820 Preference Shares, which are convertible into Common Shares
     as described under Item 4, and of options to purchase an aggregate of 5,100
     Common Shares, which options were issued to Messrs. Bunce and Tunnell, in
     consideration of their service as directors of the Company, which options
     are held for the benefit of the Reporting Persons. As of February 28, 2002,
     the Investors collectively beneficially owned an aggregate of 14,356,832
     Common Shares, assuming the full conversion of the Preference Shares into
     Common Shares and the full exercise of the options to purchase Common
     Shares. By reason of their relationships with the Investors, under Rule
     13d-3 under the Exchange Act, each of HFCI IV Bermuda and HFI IV Bermuda
     may be deemed to own beneficially all of the Common Shares that are
     beneficially owned by the Investors.

     Assuming the full conversion of the Preference Shares into Common Shares
     and the full exercise of the options to purchase Common Shares, as of
     February 28, 2002, the 14,356,832 Common Shares collectively beneficially
     owned by the Reporting Persons would represent approximately 35.6% of the
     outstanding Common Shares, after giving effect to the new issuance of
     Common Shares upon the full conversion of the Preference Shares into Common
     Shares, the full exercise of all options to purchase Common Shares and
     based on the 27,586,184 Common Shares outstanding as of September 30, 2002
     as set forth in the Company's Form 10-Q for the quarter then ended.

(b)  The Investors collectively have beneficial ownership of 14,356,832 Common
     Shares, assuming the full conversion of the Preference Shares into Common
     Shares and the full exercise of the options to purchase Common Shares. Of
     these Common Shares, 12,745,820 Common Shares are represented by 12,745,820
     Preference Shares, which even if not converted into Common Shares would in
     the aggregate be entitled to the voting power equivalent to 12,745,820
     Common Shares. Each Investor exercises voting power and dispositive power
     over its holdings of such shares through its respective general partner,
     which, in turn, acts through its respective general partner.

(c)  See Item 4 above. On January 1, 2003, each of Mr. Bunce and Mr. Tunnell, in
     consideration of his service as a director of the Company, was granted
     options to purchase 1,500 Common Shares at a per share price of $30.665,
     which options expire on January 1, 2013. Except as otherwise described
     herein, during the last sixty days there were no transactions effected by
     the Reporting Persons or by any of the persons set forth on Schedule I
     hereto.

(d)  Except as set forth in this Item 5, no person other than each respective
     record owner referred to herein of the Common Shares and the Preference
     Shares is known to have the right to receive or the power to direct the
     receipt of dividends from, or the proceeds from the sale of, such Common
     Shares or Preference Shares.

Item 6 of the Schedule 13D is hereby amended and supplemented by adding the
following:
