Parnassus Workplace Fund

Parnassus Funds Quarterly Report: March 31, 2012

Ticker: PARWX

As of March 31, 2012, the NAV of the Parnassus Workplace Fund was $22.64, so the total return for the quarter was 15.28%. This compares to a gain of 12.58% for the S&P 500 Index ("S&P 500") and 12.43% for the Lipper Large-Cap Core Average, which represents the average large-cap core fund followed by Lipper ("Lipper average"). The Workplace Fund had a very good quarter, beating both of its benchmarks by a substantial margin.

Below is a table comparing the Parnassus Workplace Fund with the S&P 500 and the Lipper average for the past one-, threeand five-year periods, as well as for the period since inception. You can see from the table that the Workplace Fund beat the Lipper average for all time periods and it also beat the S&P 500 for all time periods except for the one-year return. The Fund has a remarkable track record. For the past five years, the Workplace Fund has the third best record of the 820 large-cap core funds followed by Lipper.1 The Workplace Fund is also the best-performing of all the Parnassus Funds for the period since inception almost seven years ago.

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 S&P 500 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. 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 contain this and other information. The prospectus or summary prospectus can be obtained on the Parnassus website, or by calling (800) 999-3505. As described in the Fund's current prospectus dated May 1, 2012, 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, 2013. This limitation may be continued indefinitely by the Adviser on a year-to-year basis.

The philosophy behind the Parnassus Workplace Fund is that good workplaces make for good businesses and good businesses will ultimately give shareholders good returns. For the past seven years, the Parnassus Workplace Fund has shown this to be true. We think that good workplaces attract the best employees and that the best employees are able to infuse businesses with creativity and innovation, enabling them to prosper and grow.

Company Analysis

Four companies made the most significant contributions to the Fund's strong quarter, with each of them adding 21¢ or more to the value of each fund share. The biggest winner was Seagate Technology, a maker of hard-disk drives, whose stock soared an amazing 64.3% from $16.40 to $26.95, while contributing 23¢ to each fund share. Despite some component shortages due to the floods in Thailand, Seagate was able to ship more disk drives than expected during the quarter, since most of its operations were unaffected by the flooding. Strong demand and robust pricing for disk drives boosted the company's profits.parwx composition

Shares of San Francisco-based Wells Fargo climbed 23.9% from $27.56 to $34.14, adding 23¢ to the Fund's NAV. The bank is reaping the rewards of prudent lending decisions made during the boom years, as it uses its healthy balance sheet to take market share from weakened competitors who are saddled with bad loans. Wells Fargo now originates 30% of all mortgages in America and will benefit enormously as the housing market recovers.

First Horizon, a Tennessee-based bank, added 22¢ to the NAV, as its stock came roaring back from a depressed level during a difficult period, climbing 29.8% from $8.00 to $10.38. The bank faced problems in the 2007-through-late 2011 time frame because of a poorly-timed expansion outside of Tennessee with construction loans, mortgages and home-equity lending; a high percentage of these loans went bad. It appears that the losses from these loans have been contained and the bank has strengthened its balance sheet. The Fund was able to acquire its shares at bargain-basement prices, so our shareholders have benefited. We think the bank has strong earnings power, and the current management team has learned a lesson from its predecessors' disastrous out-of-state forays, and is committed to building shareholder value.

Qualcomm, a provider of software and semiconductors used in cellular telephones, soared 24.4% during the quarter from $54.70 to $68.02 while contributing 21¢ to each fund share. The company is hitting on all cylinders, as it beat earnings expectations last quarter. Its licensing division is benefiting from the growth in smart phones and tablets, while its semiconductor division won a contract for the baseband chip for the Apple iPhone 4S.
