The principal executive offices of the Fund are located at 101 Huntington
Avenue, Boston, MA, 02119-7603.

ITEM 2.  IDENTITY AND BACKGROUND

     (a) - (c) This Schedule 13D is being filed by The Commerce Group Inc.
(the "Reporting Person"),  a corporation formed under the laws of

(excluding traffic violations or similar misdemeanors).

     (e) During the past five years, neither the Reporting Person nor any of
the persons listed on Annex A has been a party to a civil proceeding of a
judicial or administrative body of competent jurisdiction and as a result of

                                            SCHEDULE 13D
                                            AMENDMENT No. 4
                                            DECEMBER 28, 2001

ITEM 4.  PURPOSE OF TRANSACTION

     The shares of beneficial interest of the Fund ("Shares") held by the
Reporting Person were acquired in the ordinary course of business by the
Reporting Person for the purpose of investment and capital appreciation.  In
pursuing this investment philosophy, the Reporting Person routinely monitors
the performance, trading prices, investment strategy and portfolio securities
of the Fund, and of other investment funds in which it invests, and may
discuss such matters with fund management, shareholders, or others.  The
Reporting Person, as an insurance company holding company, is entitled to
file securities ownership reports required by the Securities and Exchange Act
of 1934 on Schedule 13G.  Under amended rules under the Securities Exchange
Act of 1934, a person reporting on Schedule 13G may elect to convert such
filing to a Schedule 13D, in part, to ensure that discussions with
management, or other actions by the Reporting Person, do not limit the
Reporting Person's ability to acquire additional Shares, or to vote the
shares it already owns.  Accordingly, in order to maintain desired
flexibility for such transactions and discussions, the Reporting Person has
elected to convert its ownership filing on Schedule 13G to a filing on
Schedule 13D.

     The matters which the Reporting Person intends to consider, discuss or
pursue may include additional purchases of Shares, ceasing the purchase of
additional Shares, sales of Shares or one or more of the items described in
items (a) through (j) of Item 4.  Whether any of such actions are taken by
the Reporting Person will depend upon the Reporting Person's evaluation of
several factors, including the Fund's business and prospects, future
developments, the level of discount in Share market prices from net asset
value ("NAV"), the performance of the Funds' investments, the availability of
funds to the Reporting Person, alternative uses of funds, stock and money
market conditions, and general economic conditions. Such factors may
materially affect the Reporting Person's decision to purchase additional
Shares, or take other actions, and may result in the Reporting Person's
increasing its ownership to a majority or more of the outstanding Shares,
and/or proposing changes in operations, governance or capitalization of the
Fund.  The Reporting Person will review its investment in the Fund from time
to time and reserves the right to take or not take any action it deems to be
in its best interest or to change its intention as set forth in this Item 4.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

     (a) The Fund's reports with the Securities and Exchange Commission
report that 15,002,724 Shares are outstanding.  Based upon such number, the
Reporting Person beneficially owns 35.1% of the Fund's outstanding Shares.

     The Reporting Person is the beneficial owner (through its insurance
subsidiaries as listed below) of 5,268,600 Shares, over which it has sole
power of disposition and voting.  Such number of Shares represents
approximately 35.1% of the outstanding Shares.

                                              Shares              Cost
   The Commerce Insurance Company            4,833,100          $52,338,448
   American Commerce Insurance Company         300,000            3,106,588
   Commerce West Insurance Company             135,500            1,496,558

                  Totals                     5,268,600          $56,941,594

Common Stock, all of which were made on the New York Stock Exchange (see
attached Annex B).  Required disclosure of prior purchases have been reported

respect to any securities of the Fund, including, but not limited to, the
transfer or voting of any such securities, finders' fees, joint ventures,
loan or option arrangements, puts or calls, guarantees of profits, division
of profits or loss, or the giving or withholding of proxies.
