STRONG MUNICIPAL ADVANTAGE FUND
Effective January 1, 1998, the Strong Municipal Advantage
Fund intends to invest up to 10% of its net assets in non-
investment grade debt obligations (otherwise known as high-
yield (high-risk) securities or "junk bonds") that are rated
in the fifth-highest rating category (e.g., BB by Standard &
Poor's Ratings Group) or unrated securities of comparable
quality. BB securities compose the tier immediately below
investment grade and are considered the least speculative
non-investment grade security. Please see pages I-17
