A new section, "Trust Performance" is added to the prospectus description of
each Trust.
Advertising and sales literature may state past total return performance
(changes in market prices with dividends reinvested, divided by the initial
offer price) for various periods, which may be compared to performance of one
or more market indices. Trust returns reflect deduction of actual expenses and
maximum sales charges, which may be accompanied by returns without specified
sales charges. Past performance is not assurance of future results.
