On March 31, 2009, the U.S. Department of Treasury announced the second
extension of the Department's Temporary Guarantee Program for Money Market Funds
from April 30, 2009 through September 18, 2009 (the "Program"). The Board of
Trustees of each of the money market funds listed above (each, a "Fund" and
collectively, the "Funds"), which currently participate in the Program, has
approved the Funds' participation in the second extension of the Program.

Similar to the prior phase of the Program, and subject to certain conditions and
limitations, share amounts held by investors in each of the Funds as of the
close of business on September 19, 2008 are guaranteed against loss under the
Program in the event the market-based net asset value per share is less than
$0.995 (i.e., does not round to $1.00) (a "guarantee event") and a Fund
subsequently liquidates. The Program only covers the amount a shareholder held
in a Fund as of the close of business on September 19, 2008 or the amount a
shareholder holds if and when a guarantee event occurs, whichever is less.
Accordingly, Fund shares acquired by investors after September 19, 2008
generally are not eligible for protection under the Program. A shareholder who
has continuously maintained an account with a Fund since September 19, 2008
would receive a payment for each protected share equal to the shortfall between
the amount received in the liquidation and $1.00 per share in the case of a
guarantee event. The Program is subject to an overall limit of approximately $50
billion for all money market funds participating in the Program.

The cost to participate in the second extension of the Program will be borne by
each Fund without regard to any expense limitation currently in effect for the
Fund.


        Shareholders should retain this Supplement for future reference.
