                                            SCHEDULE 13D
                                            AMENDMENT No. 2
                                            JULY 25, 2002

ITEM 4.  PURPOSE OF TRANSACTION

     The shares of beneficial interest of the Fund ("Shares") held by the
Reporting Person were acquired and are being held 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 elected to convert its
ownership filing on Schedule 13G to a filing on Schedule 13D with the filing
of its initial 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 of General Reporting Rules.  Whether any of
such actions are taken by From time to time, the Reporting Person may sell
Shares or purchase additional Shares, depending on various factors, 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 does not have a specific plan or proposal that relates to or
would result in any of the actions described in items (b) through (j) of Item
4 of General Reporting Rules, though 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 11,151,287 Shares are outstanding.  Based upon such number, the
Reporting Person beneficially owns 34.8% of the Fund's outstanding Shares.

(b) Reporting Person is the beneficial owner (through its insurance
subsidiaries as listed below) of 3,875,143 Shares, over which it has sole
power of disposition and voting.  Such number of Shares represents
approximately 34.8% of the outstanding Shares.
