Parnassus Mid Cap Growth Fund Fonds

The fund normally invests at least 80% of its net assets (plus borrowings for investment purposes) in mid-sized growth companies. The fund will not automatically sell or cease to purchase stock of a company it already owns just because the company's market capitalization grows or falls outside the ranges of the Russell Midcap® Growth Index, which are subject to change. The fund may normally invest up to 20% of its net assets in smaller- and larger-capitalization companies.
