          London Funds.

ITEM 4.   PURPOSE OF TRANSACTION.
          ----------------------
          From time to time, the Reporting Persons have acquired beneficial
          ownership of Shares in the ordinary course of business for investment
          purposes and have held Shares in such capacity. The Reporting Persons,
          collectively, are currently one of the Fund's largest stockholders.

          The Reporting Persons believe the Board of Directors of the Fund has
          failed to take meaningful actions to solve the persistent
          under-performance problem of the Fund's net asset value ("NAV") with
          respect to its benchmark, the Taiwan Weighted Stock Exchange Index
          ("TAIEX"). In addition, the Reporting Persons are concerned about the
          Fund's investment manager's record of appointing portfolio managers
          and its potential

                              (Page 5 of 12 Pages)

          implications on the Fund and its performance.

          NAV Performance
          ---------------

          The Reporting Persons are concerned about the performance of the Fund
          as compared to its benchmark index.

          The portfolio review prepared by the Fund's investment manager, HSBC
          Asset Management (Taiwan) Limited ("HSBC"), on June 2003 shows that
          the performance of the Fund was very poor when compared to its
          benchmark index. The report states that the annualized total return of
          the Fund since inception in December 1986, assuming dividends and
          capital gains were re-invested, was 5.90% compared to an annualized
          total return for the Taiwan Weighted Stock Exchange Index (TAIEX) of
          9.99%. These figures translate to a simple conclusion: the Fund has
          provided only 60% of the Taiwanese equity market appreciation.

          Since HSBC began managing the Fund in August 2001, the Fund has
          under-performed its benchmark on a consistent basis as the following
          table shows:

                              TWN NAV      TAIEX Index     % Under
                              % change      % change     Performance
                              --------      --------     -----------
          Year to date         15.09%        19.33%         -4.25%
          1 year                3.41%         6.88%         -3.47%
          2 years               7.06%        19.50%        -12.43%
          Source: Bloomberg. Information as of August 1, 2003

          The Fund's objective is to attain long-term capital appreciation by
          investing in the Taiwan equity market and out-performing its benchmark
          index. As such, it was meant to be a vehicle by which investors could
          implement their asset strategy in Taiwan as part of their global
          portfolio. History shows, however, that the Fund's objective has not
          been met. Performance has lagged the benchmark by a significant
          margin.

          The Reporting Persons believe that the performance of the Fund is
          unacceptable. We believe that the Board has clearly failed in one of
          its principal tasks, which is to ensure that the investment manager
          delivers a performance compared to the benchmark that serves the
          shareholders' best interests. The Reporting Persons, as any other
          shareholders, need to know that the Fund will perform consistently at
          least as well as the benchmark index so as not to negate any country
          asset allocation decision.

          The Fund's poor performance also concerns the Reporting Persons
          because they believe that the Fund, while intending to outperform its
          benchmark, may make investment decisions which may considerably
          increase the level of investment risk and may eventually increase the
          probability of a greater market price discount to NAV and greater
          losses to stockholders.

          Investment Manager's Record of Appointing Portfolio Managers
          ------------------------------------------------------------

          The Reporting Persons are concerned about HSBC's record of appointing
          portfolio managers.

          After the departure of Mr. Albert King as portfolio manager of the
          Fund and contemporaneous with the change in ownership of HSBC, from
          and after 2001 HSBC seems to have embarked upon a risky, and certainly
          not beneficial for the shareholders' best interests, process of
          frequently replacing the Fund's portfolio managers.

          In May 2002 the Fund announced that Ms. Li-Jeng Chen had resigned from
          her position as the portfolio manager of the Fund in connection with
          her decision to leave HSBC to pursue other interests. The Fund further
          announced that Mr. Vincent Lai would succeed Ms. Chen as the Fund's
          lead portfolio manager.

          Approximately a year later, on July 24, 2003, the Fund announced that
          Mr. Vincent Lai had also resigned from his position as the portfolio
          manager of the Fund in connection with his decision to leave HSBC to
          pursue other interests. The Fund further announced that Mr. Alan Huang
          would be acting as the Fund's lead portfolio manager.

          As stated above, the Reporting Persons believe that HSBC has not only
          failed to deliver any meaningful value to shareholders through
          investment performance but has also added an unacceptable degree of
          risk by replacing portfolio managers in such a short period of time.
          We believe that lack of consistency in producing returns and the
          uncertainty regarding portfolio managers negatively affect shareholder
          value and are not in the shareholders' best interests, given that not
          only has the Fund's net asset value under-performed the benchmark
          index but the Fund's discount to NAV has tended to increase.


          Possible Actions
          ----------------

          The Reporting Persons believe that management and the Board should now
          openly and publicly commit to the stockholders to address the
          substantial and persistent under-performance of the Fund as compared
          to its benchmark index and to enhance stockholder value through
          whatever means necessary, with no prejudice for or against any option
          (e.g., open-ending (including by way of merger), liquidation,
          conversion to interval status, conversion to an index-based
          exchange-traded fund (or, if permissible, an actively managed ETF),
          termination of the investment management agreement, etc.).

          The Reporting Persons would consider supporting stockholder proposals
          aimed at addressing, in a more meaningful manner, the Fund's discount
          to NAV and enhancing stockholder value, as well as a Board that is
          fully committed to openly serving the best interests of the Fund's
          stockholders. Such proposals might include, but are not necessarily
          limited to, an opposing slate of directors who would be committed to
          addressing the discount and any of the actions described above or
          other actions intended to terminate the

                              (Page 7 of 12 Pages)

          Fund's investment advisory agreement with HSBC. The Reporting Persons
          also may consider submitting nominees for election as directors or a
          stockholder proposal for consideration at the next meeting of
          stockholders of the Fund.

          In addition to the foregoing, the Reporting Persons may consider the
          feasibility and advisability of various alternative courses of action
          with respect to their investments in the Fund, and the Reporting
          Persons reserve the right, subject to applicable law, (i) to hold
          their Shares as passive investors or as active investors (whether or
          not as members of a "group" with other beneficial owners of Shares or
          otherwise), (ii) to acquire beneficial ownership of additional Shares
          in the open market, in privately negotiated transactions or otherwise,
          (iii) to dispose of all or part of their holdings of Shares, (iv) to
          take other actions which could involve one or more of the types of
          transactions or have one or more of the results described in Item 4 of
          this Schedule 13D, or (v) to change their intentions with respect to
          any or all of the matters referred to in this Item 4. The Reporting
          Persons' decisions and actions with respect to such possibilities will
          depend upon a number of factors, including, but not limited to, the
          actions of the Fund, market activity in the Shares, an evaluation of
          the Fund and its prospects, general market and economic conditions,
          conditions specifically affecting the Reporting Persons and other
          factors which the Reporting Persons may deem relevant to their
          investment decisions.

          Except as set forth herein, no contract, arrangement, relationship or
          understanding (either oral or written) exists among the Reporting
          Persons as to the acquisition, disposition, voting or holding of
          Shares. Except as set forth herein, no Reporting Person has any
          present plan or proposal that would result in or relate to any of the
          transactions required to be described in Item 4 of Schedule 13D.
