Parnassus Small-Cap Fund

Parnassus Funds Quarterly Report: September 30, 2011

As of September 30, 2011, the NAV of the Parnassus Small-Cap Fund was $18.79, resulting in a loss of 23.12% for the third quarter. By comparison, the Russell 2000 Index of smaller companies ("Russell 2000") had a loss of 21.87% and the Lipper Small-Cap Core Average, which represents the average small-cap core fund followed by Lipper ("Lipper average"), had a loss of 21.33%. For the year-to-date, the Small-Cap Fund is down 21.54%, compared to a loss of 17.02% for the Russell 2000 and a loss of 16.13% for the Lipper average.

The Fund's performance for this year looks terrible, but our longer-term performance still looks pretty good. Below is a table comparing the performance of the Small-Cap Fund with that of the Russell 2000 and the Lipper average for the one-, threeand five-year periods and the period since inception. As you can see from the table, we're behind for the one-year period, but we're well ahead of both our benchmarks for the three- and five-year periods and the period since inception.

One reason our performance looks so bad this year is that many of our stocks have been hit by panic-selling amidst the sharp downdraft of the stock market. We think that many of these quoted prices are far below the stocks' intrinsic value, and when reason prevails once again, the quotes will be substantially higher. We have not changed our investment objective and we're picking stocks the same way we've always done for the Small-Cap Fund, and we think there's a lot of intrinsic value in our portfolio.

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. Returns shown in the table do not reflect the deduction of taxes a shareholder may pay on fund distributions or redemption of shares. The Russell 2000 Index is an unmanaged index of common stocks, and it is not possible to invest directly in an index. Index figures do not take any expenses, fees or taxes into account, but mutual fund returns do. Small-cap companies can be particularly sensitive to changing economic conditions and have fewer financial resources than large-cap companies. Before investing, an investor should carefully consider the investment objectives, risks, charges and expenses of the Fund and should carefully read the prospectus, which contains this and other information. The prospectus is on the Parnassus website, or one can be obtained by calling (800) 999-3505. As described in the Fund's current prospectus dated May 1, 2011, Parnassus Investments has contractually agreed to limit the total operating expenses to 1.20% of net assets, exclusive of acquired fund fees, until May 1, 2012. This limitation may be continued indefinitely by the Adviser on a year-to year basis.

Company Analysis

Five stocks reduced the value of each fund share by 29¢ or more during the quarter, with no company making a substantial positive contribution. The one that hurt us the most was Quicksilver Resources, a natural gas-producer. The stock sank 48.6% during the quarter from $14.76 to $7.58 for a loss of 38¢ for each fund share. Natural gas prices dropped 15% during the quarter from $4.33 to $3.67 per million British thermal units, and this hurt the stock, but the stock sank even further when the company announced plans to spend more on drilling programs without any indication that production would be higher. Despite the bad news, we're holding the stock because the price is so low, and we expect that Quicksilver will be able to increase production and revenue over the next few years.

Oil- and gas-producer W&T Offshore saw its stock fall 47.3% from $26.12 to $13.76, while cutting 33¢ off the NAV. Crude oil prices dropped sharply during the quarter from $95 to $79 a barrel, and the company's drilling costs have not dropped as much as the price of crude oil. We're holding the stock, since we expect oil prices to rise again and drilling costs to drop.

Homebuilder PulteGroup dropped 48.4% during the quarter from $7.66 to $3.95, chopping 33¢ off the NAV. See the discussion on PulteGroup in the Parnassus Fund section to get my views on the stock.

Brocade Communications, a provider of storage and networking equipment, sliced 31¢ off each fund share, as its stock fell 33.1% from $6.46 to $4.32. The company announced quarterly results that were below its previous guidance. Brocade's financial results have been inconsistent since it acquired Foundry Networks in 2008, but we think execution will improve over time. The company has the leading market share in fiber channel for the data center and a strong product platform in the growing networking equipment space.parsx composition

First Horizon, a Tennessee-based bank, cut 29¢ off each fund share, as its stock sank 37.5% from $9.54 to $5.96. Investors are concerned about the bank's exposure to mortgages and home equity loans in the national market. Early in the last decade, the bank had a disastrous foray into the national lending market, and the stock is still suffering the consequences. We think the bank can handle any additional losses it may incur, because of its strong balance sheet and earning power. First Horizon has now pulled back to its base in Tennessee, where it has profitable, well-managed operations. Selling at only 75% of tangible book value, the stock is on the bargain table.
