The following  supplements  the "Purchase and  Redemption of Shares"  section of
each Fund's Statement of Additional Information

Use of Financial  Services Firms.  Investment  dealers and other firms ("Firms")
provide varying arrangements for their clients to purchase and redeem the Fund's
shares,  including  higher minimum  investments,  and may assess  transaction or
other  fees.  Firms may  arrange  with their  clients  for other  investment  or
administrative services. Firms may independently establish and charge additional
amounts  to their  clients  for such  services.  Firms  also may hold the Fund's
shares in nominee or street name as agent for and on behalf of their  customers.
In such instances,  the Fund's transfer agent,  SSC (the "Transfer  Agent") will
have no  information  with  respect to or control  over the accounts of specific
shareholders.  Such  shareholders  may  obtain  access  to  their  accounts  and
information  about their  accounts only from their Firm. The Fund has authorized
the Shareholder  Service Agent to pay to these Firms,  out of the Fund's assets,
up to 0.10 of 1% for  services  and other  expenses  relating  to these  nominee
accounts  including  all of the  individual  sub-accounting  necessary  for  the
processing  of  purchases  and  redemptions  as  part  of the  brokerage  sweep,
processing  of daily  dividends  and  monthly  payment/reinvestment  of  accrued
dividends,  providing  periodic  statements,  tax  reporting,  changing  account
information   for   customers,    administering   daily   wire   transfers   and
reconciliations  with the Fund and other  similar  functions.  These  Firms also
coordinate  with the Transfer Agent in connection  with the Fund's check writing
program.  In  addition,  certain  privileges  with  respect to the  purchase and
redemption  of shares or the  reinvestment  of  dividends  may not be  available
through such Firms. Some Firms may participate in a program allowing them access
to  their  clients'  accounts  for  servicing  including,   without  limitation,
transfers of registration and dividend payee changes;  and may perform functions
such  as  generation  of  confirmation   statements  and  disbursement  of  cash
dividends.
