A "business day of the Portfolio" is any day on which both the Federal
Reserve Bank of New York and The Bank of New York, the Trust's custodian bank,
are open for business. The Portfolio, however, reserves the right to change
the time for which purchase and redemption requests must be submitted to the
Portfolio for execution on the same day on any day when the U.S. primary
broker-dealer community is closed for business or trading is restricted due to
national holidays.
