Important Information

ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG) GUIDELINES The Parnassus strategies evaluate ESG factors as part of the investment decision-making process, considering a range of impacts they may have on future revenues, expenses, assets, liabilities and overall risk. The strategies also utilize active ownership to encourage more sustainable business policies and practices and greater ESG transparency. Active ownership strategies include proxy voting, dialogue with company management, sponsorship of shareholder resolutions, and public policy advocacy. There is no guarantee that the ESG strategies will be successful.

Mutual fund investing involves risk, and loss of principal is possible.

Earnings Growth is not a measure of future performance.

Shares of the Funds are offered only for sale in the United States. The Funds are not registered for sale in any other country. Nothing on this site should be considered a solicitation to buy or an offer to sell shares of the Funds in any jurisdiction where the offer or solicitation would be unlawful under the securities laws of such foreign jurisdiction or the United States.

For the current holdings of the Parnassus Core Equity Fund, the Parnassus Growth Equity Fund, the Parnassus Value Equity Fund, the Parnassus Mid Cap Fund, the Parnassus Mid Cap Growth Fund, the Parnassus International Equity Fund, the Parnassus Core Select ETF, and the Parnassus Value Select ETF, please visit each fund’s individual holdings page. Fund holdings are subject to change at any time.

ETFs are subject to additional risks that do not apply to conventional funds, including the risks that the market price of an ETF's shares may trade at a premium or discount to its net asset value, an active secondary trading market may not develop or be maintained, or trading may be halted by the exchange in which they trade, which may impact an ETF's ability to sell its shares. Shares of any ETF are bought and sold at market price (not NAV) and are not individually redeemed from the ETF. Brokerage commissions will reduce returns.

For current quarter-end standardized performance and disclosure information, please click here.

Performance data quoted represent past performance and are no guarantee of future returns. Current performance may be lower or higher than the performance data quoted. Current performance information to the most recent month end is available on the Parnassus website (www.parnassus.com). Investment return and principal value will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original principal cost.

Before investing, an investor should carefully consider the investment objectives, risks, charges and expenses of a fund and should carefully read the prospectus or summary prospectus, which contains this and other information and can be found in our Literature and Forms section or by calling (800) 999-3505 for a mutual fund prospectus or (855) 514-4443 for an ETF prospectus.

The Parnassus Funds are distributed by Parnassus Funds Distributor, LLC.
