John Hancock Funds

Supplement dated September 21, 2007,

to the Statement of Additional Information

In the section “Additional Services and Programs”, the following disclosure has been added:

Section 403(b)(7) of the Internal Revenue Code permits public school employers and employers of certain types of tax-exempt organizations to establish for their eligible employees custodial accounts for the purpose of providing for retirement income for such employees. Effective September 25, 2007, Treasury regulations impose certain conditions on exchanges between one custodial account intended to qualify under Section 403(b)(7) (the “exchanged account”) and another contract or custodial account intended to qualify under Section 403(b) (the “replacing account”) under the same employer plan (a “Section 403(b) Plan”). Specifically, the replacing account agreement must include distribution restrictions that are no less stringent than those imposed under the exchanged account agreement, and the employer must enter in an agreement with the custodian (or other issuer) of the replacing account under which the employer and the custodian (or other issuer) of the replacing account will from time to time in the future provide each other with certain information.

These Regulations supersede the conditions specified under Rev. Rule 90-24 that were in effect for exchanges of Section 403(b) contracts or accounts prior to September 25, 2007. Due to these Regulations, effective September 25, 2007:

1) The funds will no longer accept requests to establish new John Hancock custodial 403(b)(7) accounts intended to qualify as a Section 403(b) Plan; and

2) The funds will no longer accept requests for exchanges or transfers into your John Hancock custodial 403(b)(7) accounts (i.e., where yours is the replacing account); and

3) The funds will require certain signed disclosure documentation in the event:

• You established a John Hancock custodial 403(b)(7) account with a fund prior to September 24, 2007; and

• You direct the fund on or after September 25, 2007 to exchange or transfer some or all of your John Hancock custodial 403(b)(7) account assets to another 403(b) contract or account (i.e., where the exchanged account is with the fund).

In the event that the fund does not receive the required documentation, and you nonetheless direct the fund to proceed with the transfer, the transfer may be treated as a taxable transaction.
