The Fund also takes environmental, social and governance factors into account in making investment decisions. As of September 30, 2012, the Parnassus Equity Income Fund's assets totaled $4.8 billion.

Mutual fund investing involves risk, and loss of principal is possible. Common stock prices fluctuate based on changes to a company's financial condition and on overall market and economic conditions. In addition to large-cap companies, the Parnassus Equity Income Fund may also invest in small- and mid-cap companies, which can be particularly sensitive to changing economic conditions and have fewer financial resources than large-cap companies.

The Parnassus Funds are underwritten and distributed by Parnassus Funds Distributor, a subsidiary of Parnassus Investments and a FINRA member.

Before investing, an investor should carefully consider the investment objectives, risks, charges and expenses of the fund and should carefully read the prospectus or summary prospectus, which contains this information.
