Supplement to the Current Prospectus

Effective  April 1,  2008,  the  paragraph  above the  table in the  sub-section
entitled "Expense Table" under the main heading "Expense Summary" is restated in
its entirety as follows:

This  table  describes  the  fees  and  expenses  that you may pay when you buy,
redeem,  and hold shares of the fund.  The annual fund  operating  expenses  are
based on expenses  incurred  during the fund's most  recently  completed  fiscal
year,  adjusted to reflect  annualized  expenses  and current fee  arrangements.
These expenses do not reflect the fees or charges imposed by a fee-based wrap or
transaction  fee program  through  which an investment is made. If these fees or
charges had been  included,  your  expenses  would be higher.  The fund's annual
operating expense may vary in future years.

Effective April 1, 2008, the first paragraph of the sub-section  entitled "Class
W Shares" under the main heading  "Description  of Share Classes" is restated in
its entirety as follows:

Class W Shares

Class W shares  generally  are available  only to: (1)  fee-based  wrap programs
sponsored by financial  intermediaries  that have entered into an agreement with
MFD to offer Class W shares to their clients;  and (2)  transaction fee programs
offered by financial intermediaries that have entered into an agreement with MFD
to offer  Class W shares to certain of their  clients  who charge an  investment
advisory fee. The use of Class W shares by a financial  intermediary will depend
on, among other  things,  the  structure  of the  particular  fee-based  wrap or
transaction fee program.

Effective  April 1, 2008,  the first  paragraph  under the main  heading "How to
Purchase, Redeem and Exchange Shares" is restated in its entirety as follows:

You may  purchase,  redeem,  convert,  and  exchange  your  Class W shares  only
through: (1) a fee-based wrap program sponsored by a financial intermediary that
has entered into an agreement  with MFD to offer Class W shares to the financial
intermediary's clients; and (2) a transaction fee program offered by a financial
intermediary that has entered into an agreement with MFD to offer Class W shares
to certain  of their  clients  who charge an  investment  advisory  fee.  Please
contact your financial intermediary for additional information on the procedures
for


purchasing,  redeeming,  converting,  and  exchanging  shares of the  fund,  and
additional  investment  requirements  of the fee-based wrap or  transaction  fee
program.  Your financial  intermediary  generally will charge fees, which are in
addition to those described in this prospectus.

Effective April 1, 2008, the fourth paragraph of the sub-section entitled "How
to Purchase Shares" under the main heading "How to Purchase, Redeem and Exchange
Shares" is restated in its entirety as follows:

are no initial or subsequent  investment  minimums  except as may be required by
your financial intermediary's fee-based wrap program.  Generally with respect to
shares  purchased for a fee-based  transaction  program,  the initial minimum is
$100,000 per transaction and there are no subsequent investment minimums.
