Fleet National Bank is a direct, wholly owned subsidiary of FleetBoston Financial Corporation, a U.S. financial holding company. Under the rules for mutual funds, the transaction resulted in a change of control of the Funds' investment advisor and, therefore, an assignment of its investment advisory contract with the Funds.

The new contract is substantially identical in all respects to the contract in effect prior to November 1, 2001 except for its effective and termination dates and other non-material changes. As of November 1, 2001, the Funds' investment advisor is a wholly owned subsidiary of Fleet/Liberty Holdings, Inc., which in turn is a wholly owned subsidiary of Fleet National Bank, which in turn is a wholly owned subsidiary of FleetBoston Financial Corporation.
