The SAI is hereby supplemented to reflect a change in the non-fundamental policy
regarding pledging, hypothecating or mortgaging of assets for each of the

Fund and Tax-Managed International Equity Fund. Accordingly, the first
non-fundamental policy, under the section entitled "Investment Limitations," on

     Pledge, mortgage or hypothecate assets except to secure permitted
     borrowings or related to the deposit of assets in escrow or in segregated
     accounts in compliance with the asset segregation requirements imposed by
     Section 18 of the 1940 Act, or any rule or SEC staff interpretation
     thereunder.
