PARNASSUS FUNDS Semiannual Report  •  2016

August 12, 2016

Dear Shareholder:

Stocks have been on a roller-coaster this year. The S&P 500 Index dropped 10.3% from the beginning of the year to February 11, 2016, and then shot up 13.5% to close the first quarter in positive territory. There were more surprises during the second quarter as the British voted on June 23 to leave the European Union. This caused the market to drop 5.3% in three days, before gaining most of it back by the end of the quarter.

As you will see when you read this report, most of our funds had a rather lackluster quarter. The long-term records remain excellent, but this was not a great quarter for most of our funds.

The one exception was the Parnassus Mid Cap Fund – Investor Shares, which had a remarkable quarter, gaining 4.96% compared to 3.18% for the Russell Midcap Index and 2.07% for the Lipper Mid-Cap Core Average. For the year-to-date, the Parnassus Mid Cap Fund – Investor Shares is up an amazing 8.49%, compared to 5.50% for the Russell and 3.63% for the Lipper average. I hope all you Parnassus Mid Cap Fund shareholders appreciate the efforts of portfolio managers Matt Gershuny and Lori Keith, because they’ve done a great job. I won’t try to steal their thunder by telling you how they did it, but I urge you to read their report.*

Net Asset Value (NAV) Impact

In our last quarterly report, we told you about how we were changing the way we talk about the impact one stock has on a fund’s performance. Previously, we described it by expressing the results in cents per share of the NAV. At the first of the year, we changed our methodology to describe a stock’s contribution in terms of basis points. As a reminder, a basis point is one one-hundredth of a percent or .01%. In other words, it takes one hundred basis points to make one percent.

Summer Interns

We have five research interns with us this summer and two accounting interns. Starting with the research interns, we’re happy to have Tarron Hecox with us soon after receiving his MBA from Harvard Business School. Tarron holds a graduate and an undergraduate degree from the University of Nebraska, where he studied economics, finance and accounting. Previously, he worked at William Blair & Co. and at the Howard G. Buffett Foundation. Howard Buffett is a son of Warren Buffett, who provided so much inspiration in the founding of Parnassus Investments. Tarron also holds the CPA designation, and when he’s not thinking about numbers, he enjoys golfing and running.

Robert Hamlin is an MBA candidate at the Wharton School of the University of Pennsylvania. Previously, he worked as an investment analyst at the International Finance Corporation, the development arm of the World Bank. Robert graduated from Harvard University, where he majored in social studies. He enjoys performing at stand-up comedy shows and volunteers his time to mentor social entrepreneurs through the Resolution Project.

Lannie Trieu is a senior at the Haas School of Business at the University of California at Berkeley. Last year, she interned with us at the Parnassus Asia Fund. Previously, she interned for WNC, a real estate investment firm. Lannie is an accomplished musician and has toured and given concerts in Vietnam, playing traditional Vietnamese instruments. She is a member of the Alpha Kappa Psi business fraternity, and she enjoys traveling and swimming.

Kevin Shao is a senior at the University of California at Berkeley, majoring in business administration and economics. Previously, he worked as a summer associate at Chinook Capital Group, a private equity firm. He is currently director of research at Capital Investments, a UC Berkeley investment club. Kevin enjoys sailing, cooking and playing the piano.

Adarsh Battu is a junior at the Wharton School of the University of Pennsylvania, where he plans to concentrate in finance and strategic management. Previously, he interned for a recruitment start-up called PymWym. He enjoys hiking in his free time, and he is also a volunteer science teacher at an elementary school.

We also have two accounting interns with us this summer. Brad Alman earned his associate degree in business administration from Diablo Valley College (DVC), where he graduated with honors. He is now a junior at California Polytechnic University in San Luis Obispo, majoring in financial management. Brad played for the soccer team at DVC and enjoys playing basketball and other sports in his spare time.

Timothy McIntosh is a senior at Biola University in La Mirada, California, where he studies both business management and entrepreneurship. Timothy is an Eagle Scout and a recipient of the Presidential Volunteer Service Award. He enjoys camping, hiking and boating.

Finally, I would like to thank all of you for investing with the Parnassus Funds.

Yours truly,

Jerome L. Dodson

President

PARNASSUS FUND

Ticker: Investor Shares - PARNX

Ticker: Institutional Shares - PFPRX

As of June 30, 2016, the net asset value (“NAV”) of the Parnassus Fund-Investor Shares was $39.80, resulting in a loss of 0.50% for the second quarter. This compares to a gain of 2.45% for the S&P 500 Index (“S&P 500”) and a gain of 1.14% for the Lipper Multi-Cap Core Average, which represents the average return of the multi-cap core funds followed by Lipper (“Lipper average”), so we trailed both benchmarks for the quarter. For the year-to-date, the Fund is down 1.63%, compared to a gain of 3.82% for the S&P 500 and 1.67% for the Lipper average. These returns are disappointing. In our view, however, these losses are temporary, and investors with a long-term approach should not lose capital. We’re picking stocks the same way we always have, so we believe it’s just a matter of time until the market recognizes the value of the stocks in our portfolio. When this happens, we expect our performance will recover.

Below is a table comparing the Parnassus Fund with the S&P 500 and the Lipper average over the past one-, three-, five- and ten-year periods. The Fund is behind the S&P 500 and the Lipper benchmarks for the one-year period. For the three-year

The average annual total return for the Parnassus Fund-Institutional Shares from commencement (April 30, 2015) was -3.37%. Performance shown prior to the inception of the Institutional Shares reflects the performance of the Parnassus Fund-Investor Shares and includes expenses that are not applicable to and are higher than those of the Institutional Shares. The performance of Institutional Shares differs from that shown for the Investor Shares to the extent that the classes do not have the same expenses. 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 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 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, 2016, Parnassus Investments has contractually agreed to limit total operating expenses to 0.99% of net assets for the Parnassus Fund-Investor Shares and to 0.94% of net assets for the Parnassus Fund-Institutional Shares. This agreement will not be terminated prior to May 1, 2017, and may be continued indefinitely by the Adviser on a year-to-year basis.

period, we’re trailing the S&P 500, but ahead of the Lipper average. Longer term, the Fund is beating both benchmarks for the past five-year and ten-year periods. Most striking is the ten-year number, where we have gained an average of 9.47% per year, compared to 7.41% for the S&P 500 and 6.16% for the Lipper average. This is 2.06% per year ahead of the S&P 500 and more than three percentage points per year ahead of the Lipper average.

Company Analysis

Four companies each contributed 20 basis points or more to the Fund’s return this quarter, but six subtracted 20 basis points or more from the return. Our worst performer was Perrigo, the leading producer of store-brand generic drugs, as its stock sank 29.1% from $127.93 to $90.67, cutting 69 basis points from the Fund’s return. Shares plummeted in April after longtime CEO Joe Papa resigned to become the CEO at Valeant Pharmaceuticals, and Perrigo lowered its 2016 guidance for the second time this year. The business has underperformed due to declining generic drug prices and weak growth from Omega, Perrigo’s European business. While we think John Hendrickson, Perrigo’s new CEO, is the right person for the job given his strong operational background, we’re continuing to monitor the drug pricing environment.

Motorola Solutions, a provider of communications services and networks for public safety workers, sliced 46 basis points from the Fund’s return, as its stock fell 12.9% from $75.70 to $65.97. Just last quarter, Motorola was one of our biggest winners, as investors cheered the acquisition of Airwave, Great Britain’s public safety communications network. Those cheers, however, turned to boos,

when the British voted to leave the EU. Investor sentiment soured even further on the deal, as regulators initiated a review to ensure it won’t suppress competition. Our positive opinion of Airwave hasn’t changed, as we believe it will be significantly accretive to earnings, while strengthening Motorola’s international presence. The deal was cleared by regulators after the quarter ended, and we think Britain may actually need to increase its spending on public safety, as it prepares to leave the European Union.

Allergan, an innovative pharmaceutical company best known for developing Botox, reduced the return by 41 basis points as the stock dropped 13.8% from $268.03 to $231.09. The shares sank after Pfizer terminated its plans to acquire Allergan for $160 billion. Pfizer walked away from the deal, because of new rules from the U.S. Treasury that prevent tax-lowering corporate inversions. We used the stock’s weakness to increase our position, since Allergan has an attractive collection of durable brands. We also like the fact that the company is in the process of selling its generic drug unit to Teva for $40 billion, which will enable Allergan to repurchase stock, pay down debt and acquire innovative drug companies.

As its name implies, Air Lease purchases aircraft and leases them to airlines, and its stock fell 16.6% from $32.12 to $26.78, trimming 33 basis points from the Fund’s return. The company reported better than expected earnings and held an upbeat investor day, where Air Lease highlighted its expectation to double its aircraft fleet over the next five years. Nonetheless, the stock dropped due to concerns that slowing global growth could negatively impact air traffic. Despite this concern, we believe long-term air travel demand will remain robust, and airlines will continue to utilize the financial flexibility offered by leasing.

Charles Schwab, the San Francisco-based bank and brokerage firm, saw its stock drop 9.7% from $28.02 to $25.31, for a loss of 30 basis points. The stock slid because investors pushed back their expectations for a rise in interest rates. At the beginning of the quarter, the market assigned a less than 50% probability that the Fed Funds rate would remain unchanged in the 0.25%-0.50% range by the end of 2016. In late June (on the heels of the Brexit news), this probability shot up to almost 90%. This matters for Schwab, because low rates crimp the company’s ability to profit from its bank assets and money market funds. We’re holding our Schwab position, despite this expected delay in an interest rate hike, because we think the company’s long-term prospects are terrific.

Gilead, a biotechnology firm that makes therapies for HIV and hepatitis C, sliced 21 basis points off the Fund’s return, as its stock declined 9.2% from $91.86 to $83.42. The company’s underperformance was driven by weakness in its hepatitis C business, as pricing came under pressure due to increased competition. Given Gilead’s proven track record of innovation and its strong balance sheet, we believe the company has many opportunities not only to maintain leadership in HIV and hepatitis C, but also to expand its portfolio into new therapeutic areas.

Our biggest winner was Micron Technology, which boosted the Fund’s return by 101 basis points, as its stock rose 31.4% from $10.47 to $13.76. Micron makes semiconductor memory chips, and its stock jumped as prices for dynamic random access memory (also known as DRAM) increased in June for the first time in two years. Just last quarter Micron was our biggest loser, as DRAM prices continued their fall and

investors fretted there was no end in sight. Since production capacity is growing at a slower rate than demand, we were confident DRAM prices would eventually stabilize, but we didn’t know precisely when. While we were early with our initial investment, we added to our position on the weakness, and we’re happy our conviction is beginning to pay off. We expect demand growth to continue as computing becomes even more integral to the global economy, which should push Micron’s earnings and its stock higher.

Semiconductor-equipment manufacturer Applied Materials added 37 basis points to the Fund, as its stock increased 13.2% from $21.18 to $23.97. Building on last quarter’s solid performance, the company continues to execute well, reaching an all-time high in order volume in China. The sustained outperformance and positive financial outlook has provided investors with increased confidence in the long-term trajectory of the business.

Mondelez, a leading snack company with iconic brands such as Oreo, Trident and Cadbury, contributed 32 basis points to the Fund’s return, as its stock rose 13.4% from $40.12 to $45.51. The stock spiked at the end of the quarter, after the company made a $23 billion bid for Hershey in an effort to create the world’s largest candy maker. Although Hershey swiftly rejected the offer, Mondelez’s stock still rallied, because Mondelez itself is an acquisition target – many investors believe Mondelez approached Hershey in order to fend off an acquirer. While we don’t know how these potential mergers will ultimately play out, we continue to like our investment in Mondelez due to the company’s strong brands and management’s focus on increasing operating margins.

McKesson, the largest drug distributor in the nation, added 23 basis points to the Fund’s return, as the stock jumped 18.7% from $157.25 to $186.65. Following a disappointing earnings revision in January, the company bolstered investor confidence by winning new contracts with key customers such as Walmart and acquiring attractive assets in its specialty pharmaceutical business. We view McKesson as a leader in reducing health care costs and believe the company will continue to generate strong shareholder returns.

Outlook and Strategy

The S&P 500 finished the quarter with a modest gain, but it took another wild ride to get there. As of June 23, the market was up 2.6% for the quarter. Then, voters in Britain shocked investors around the world by voting to leave the European Union, also known as “Brexit”. The fall-out was swift, as the S&P 500 fell 5.3% over the next three trading sessions. Amazingly, stocks quickly recovered almost all of the lost ground and finished the quarter in positive territory.

The ramifications of Brexit on Britain likely include job losses and lower economic growth, as more restrictive trade agreements are negotiated. This would also hurt economic growth in the European Union, as Britain is Europe’s second largest economy. U.S. investors are worried that slowing European growth will reduce export demand for American companies. Additionally, the decline in value of the British pound and euro make a bad situation worse, because revenue earned in these currencies is now worth less when converted into U.S. dollars. If this story about concerns over a foreign economy sounds familiar, it’s because it is, as the S&P 500 has endured two 10% corrections over the past year due to China’s slowing economy and falling currency. China and the European Union together represent one-third of the global economy, so there are good reasons to be concerned.

While stocks have sold off several times during the past year due to negative international developments, they’ve rebounded each time because the U.S. economy has been resilient. Consumer spending represents 70% of the U.S. economy, and low gas prices, low interest rates and low import prices all benefit the consumer.

Stock market volatility creates opportunities for even-tempered, long-term investors like ourselves, as many investors overreact and engage in panic selling or euphoric buying. Unfortunately for our funds, investors have been selling off the stocks we already own, so we have underperformed the market. We’re not happy with our recent performance, but this has happened to us before, and what we found was the best strategy was just to hold the companies we already own, if they were companies with sustainable competitive advantages and good prospects. And, in cases where we believe investors have become far too pessimistic, we’ve taken the opportunity to add to our positions at bargain prices.

Warren Buffett says it’s good news when stocks go down, because you can get more for your money if you keep buying. We agree, and while it doesn’t feel good at the moment, we believe it eventually will. We don’t know exactly when, but we believe that sooner or later the market will recognize the value we see in our securities.

PARNASSUS CORE EQUITY FUND

Ticker: Investor Shares - PRBLX

Ticker: Institutional Shares - PRILX

As of June 30, 2016, the NAV of the Parnassus Core Equity Fund-Investor Shares was $37.99. After taking dividends into account, the total return for the second quarter was 0.73%. This compares to an increase of 2.45% for the S&P 500 Index (“S&P 500”) and a gain of 3.38% for the Lipper Equity Income Fund Average, which represents the average equity income funds followed by Lipper (“Lipper average”). For the first half of 2016, the Parnassus Core Equity Fund – Investor Shares posted a return of 3.34%, which compares to gains of 3.82% for the S&P 500 and 6.38% for the Lipper average.

Below is a table that compares the performance of the Fund with that of the S&P 500 and the Lipper average. Average annual total returns are for the one-, three-, five- and ten-year periods ending June 30, 2016.

The average annual total return for the Parnassus Core Equity Fund-Institutional Shares from commencement (April 28, 2006) was 9.57%. Performance shown prior to the inception of the Institutional Shares reflects the performance of the Parnassus Core Equity Fund-Investor Shares and includes expenses that are not applicable to and are higher than those of the Institutional Shares.

Second Quarter Review

The Fund posted a modest gain for the quarter but trailed the S&P 500 by 172 basis points (a basis point is 1/100^th of 1%). Sector allocations detracted from our performance, with the most damaging effect coming from our underweight position in the index’s best-performing sector, energy. The only meaningfully positive sector allocation effect came from our underweight position in consumer discretionary stocks, which lagged the benchmark.

As for individual securities, the Fund had three losers that each reduced the Fund’s return by 34 basis points or more. The Fund’s worst performer was Perrigo, the leading producer of store-brand generic drugs. The stock sank 29.1% from $127.93 to $90.67 and cut 96 basis points from our return. Shares plummeted in April after longtime Perrigo CEO Joe Papa accepted an offer to lead Valeant Pharmaceuticals. On the same day, Perrigo lowered its 2016 earnings guidance for the second time this year. The company has suffered recently from declining generic drug prices and sluggish growth at Omega, Perrigo’s recently-acquired European business.

Motorola Solutions, a provider of communications services and networks for public safety workers, sliced 46 basis points from the Fund’s return, as its stock fell 12.9% from $75.70 to $65.97. Just last quarter, Motorola was one of our biggest winners, as investors cheered the acquisition of Airwave, Great Britain’s public safety communications network. Those cheers, however, turned to boos, when the British voted to leave the EU. Investor sentiment soured even further on the deal, as regulators initiated a review of the proposed acquisition’s effect on competition. Our opinion of the Airwave transaction hasn’t changed; we believe the deal will significantly improve Motorola’s

international presence and boost near-term earnings. Moreover, we’re happy to report that regulators approved the Airwave deal just after the second quarter ended.

Apple sliced 34 basis points from the Fund’s return as its stock fell 12.3% from $108.99 to $95.60. The stock dropped after the company reported weaker than expected earnings, driven by a shortfall in iPhone unit sales. This news sparked investor concerns that iPhone profits have peaked and that the company will be challenged to grow over the long-term. We expect Apple to keep expanding its already massive customer base, while adding new products and services to its lineup. Furthermore, the company’s balance sheet and cash generation continue to be very healthy, supporting continued share repurchases and dividend growth.

Iron Mountain was our biggest winner, as the stock rose 17.5% from $33.91 to $39.83, adding 53 basis points to the Fund’s return. During the quarter, Iron Mountain made progress on its merger with Recall, a transaction that combines the top two players in the global document storage industry. We think this deal will help Iron Mountain accelerate its revenue growth, as the smaller Recall has historically grown sales faster than Iron Mountain. Another positive is that Recall has a relatively light debt load, so the combined entity will have a healthier balance sheet than stand-alone Iron Mountain.

Mondelez, a leading snack company with iconic brands such as Oreo, Trident and Cadbury, added 46 basis points to the Fund’s return, as its stock increased 13.4% from $40.12 to $45.51. The stock spiked at the end of the quarter after the company made a $23 billion bid for Hershey. Although Hershey swiftly rejected the offer, Mondelez’s stock still rallied on speculation that Mondelez itself may be an acquisition target. Many investors believe Mondelez approached Hershey in order to fend off an unknown hostile acquirer. We don’t know how this M&A drama will ultimately play out, but in the meantime we continue to like our investment in Mondelez. The company has terrific brands, growing end-markets and a management team focused on improving profitability.

Micron Technology added 43 basis points to the Fund’s return, as its stock rose 31.4% from $10.47 to $13.76. Micron makes semiconductor memory chips, and its stock jumped as prices for dynamic random access memory (known as DRAM) increased in June for the first time in two years. Since production capacity is growing more slowly than demand, we had expected DRAM prices to stabilize and move higher at some point this year. We’re hopeful that the pricing environment will continue to improve for Micron for the remainder of 2016 and beyond.

Outlook and Strategy

The big geopolitical news during the quarter was the British majority’s decision to exit the European Union (known as “Brexit”). We expect this landmark vote to have profound political, social, economic and financial effects. We won’t know the extent or precise nature of Brexit’s impacts for years, because the United Kingdom will probably have until at least late 2018 to negotiate new trading and political relationships with the European Union and other nations. In the meantime, we’re working hard to understand how Brexit will impact our portfolio

companies. Our provisional view is that the Fund should be relatively immune to any localized disruption to British economic activity over the next few years, which is one potential effect of Brexit.

A more significant risk is that other countries may follow the UK through the EU exit door, triggering a broader continental slowdown and further weakening of the euro versus the U.S. dollar. Two potential candidates for exiting are Sweden and Denmark, which, similar to the UK, still use their own currency rather than the euro. Moreover, in the Netherlands and France, vocal political groups are pushing for Brexit-style referendums, and their nativist causes clearly got a boost from the Brexit vote. American financial markets are tied closely to Europe’s, and our portfolio companies generate significant revenue from that region, so we’ll continue to assess the risk of other countries following the UK’s lead.

We sold four stocks during the quarter. The first was Shaw Communications, a western Canadian cable company. We exited after losing confidence in Shaw’s ability to maintain its competitive position and increase its customer value proposition over the long-term. We sold eBay for similar reasons. In short, we think eBay is destined to being the number two player in an increasingly winner-take-all e-commerce market (Amazon being the presumptive winner).

We sold two other stocks for valuation reasons. After approximately a decade of ownership, we said goodbye to Northwest Natural, a utility that focuses on natural gas distribution. The stock had a great run from September of last year through the end of June. As a result, the shares no longer looked undervalued to us. The final departure was Pepsi, which we bought about five years ago. Given the muted growth potential for the company and the unlikelihood of meaningful margin expansion from here, we concluded that Pepsi’s price-to-earnings multiple of 21x was simply too high.

We added two stocks to the Fund in the quarter. The first is The Walt Disney Company, a global enterprise with businesses that include media networks, movie studios, theme parks and consumer products. The stock reached a high of $122 in August of 2015, just before management announced subscriber declines at ESPN, one of Disney’s most valuable assets. However, the stock quickly recovered in December in anticipation of the release of Star Wars: The Force Awakens. We bought the stock in May at an average price of $103, when investors again were focused on the threats related to ESPN. We acknowledge these threats, but think that there are plenty of other good things going for Disney to offset the risk.

We decided to buy Wells Fargo after many years of waiting for the right entry point. At the time of our purchase, the stock was trading at a slight discount to other regional banks, and a major discount to the overall stock market. In addition, the company had just lowered guidance for important return-on-capital measures at its May investor day. We think the company will meet or exceed these new targets, which should provide support for the stock over our three-year investment horizon. As for the quality of the company, simply put we think Wells Fargo is the best large bank in the country. It has an enviable balance of fee income and net interest income, a widely diversified customer base and a culture that emphasizes risk management.

With the addition of Wells Fargo, we have reduced our underweight position relative to the index in the financial sector. The Fund still has significant underweight positions in the energy and consumer discretionary sectors. Our largest overweight is in industrials stocks, as our allocation is almost twice that of the S&P 500. On an absolute basis, the Fund’s largest sector weight is in technology stocks. Technology also happens to be the largest sector in the index, as it includes some of the world’s most valuable public companies, such as Apple, Alphabet, Microsoft and Facebook.

Despite our slight underperformance for the year thus far, we’re confident that our investment process will lead to strong risk-adjusted returns over the long-run. Our portfolio holdings have great business prospects and attractive risk-reward profiles. We appreciate your trust in us and your investment in the Fund.

Thank you,

Semiannual Report  •  2016 PARNASSUS FUNDS

PARNASSUS ENDEAVOR FUND

Ticker: Investor Shares - PARWX

Ticker: Institutional Shares - PFPWX

As of June 30, 2016, the NAV of the Parnassus Endeavor Fund-Investor Shares was $28.62, so the total return for the quarter was 1.20%. This compares to 2.45% for the S&P 500 Index (“S&P 500”) and 1.14% for the Lipper Multi-Cap Core Average, which represents the average return of the multi-cap core funds followed by Lipper (“Lipper average”). We trailed the S&P 500, but we beat the Lipper average by a small amount. For the year-to-date, the Fund is up 1.96%, compared to 3.82% for the S&P 500 and 1.67% for the Lipper average.

Below is a table comparing the Parnassus Endeavor Fund with the S&P 500 and the Lipper average for the past one-, three-, five- and ten-year periods. If you look at the table, you’ll see that for the one-year period, the Fund lagged the S&P 500 by quite a bit – a gain of only 0.64% compared to 3.98% for the S&P 500. However, the Fund gained much more than the

The average annual total return for the Parnassus Endeavor Fund-Institutional Shares from commencement (April 30, 2015) was 1.61%. Performance shown prior to the inception of the Institutional Shares reflects the performance of the Parnassus Endeavor Fund-Investor Shares and includes expenses that are not applicable to and are higher than those of the Institutional Shares. The performance of the Institutional Shares differs from that shown for the Investor Shares to the extent that the classes do not have the same expenses. 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 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 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, 2016, Parnassus Investments has contractually agreed to limit total operating expenses to 0.95% of net assets for the Parnassus Endeavor Fund-Investor Shares and to 0.83% of net assets for the Parnassus Endeavor Fund-Institutional Shares. This agreement will not be terminated prior to May 1, 2017, and may be continued indefinitely by the Adviser on a year-to-year basis.

Lipper average – 0.64% for the Fund compared to a negative 2.30% for Lipper average. There’s quite a spread between these returns for the year, and I’m not sure what caused this. I suspect it has something to do with market volatility and uncertainty caused by the British vote to leave the European Union. As we shall see in a moment, there were also some individual stock positions that hurt the Fund in the quarter, bringing the return below that of the S&P 500, but not enough to fall behind the Lipper average.

Sometimes, stocks you don’t own are more important than ones you own. In our case, we own no energy stocks in line with our fossil-free environmental policy. The energy sector did well this quarter, so that hurt our comparative performance. However, I still think energy stocks will be weak in the future, so I think our fossil-free policy will help us later in the year.

Looking longer-term, the Parnassus Endeavor Fund beat both benchmarks for the three-, five- and ten-year periods. Going forward, we can expect a lot of fluctuations for shorter time periods, but the Fund’s long-term record looks excellent. The Fund has averaged a return of 11.57% per year for the past ten years, compared to a return of 7.41% per year for the S&P 500. We’ve been averaging more than four percentage points per year over the S&P 500. We hope to continue that performance.

Company Analysis

Beginning with last quarter’s report, we started discussing each company’s performance in percentage terms, rather than cents contributed to the NAV. We think this will provide greater clarity to a stock’s contribution toward overall returns. Each basis point is equal to 0.01% or one-hundredth of a percent. If you get confused, just remember that there are 100 basis points in one percent.

PARNASSUS FUNDS Semiannual Report  •  2016

Four companies each accounted for losses of 34 basis points or more to the Fund’s return, while only two companies added 35 basis points or more. There was no pattern to the four losers, as they all came from different industries. One makes generic medicine, one is a major biotechnology firm, one is a financial institution and one is a software company.

During the second quarter, Perrigo saw its stock sink 29.1% from $127.93 to $90.67, cutting 113 basis points off the Fund’s return. Shares plummeted after longtime CEO Joe Papa resigned to run Valeant Pharmaceuticals, as Perrigo lowered its guidance for the second time this year. Given how poorly Valeant has been doing (down over 90% from $264 on August 6, 2015 to about $22 now), it seems like Joe Papa just jumped out of the frying pan into the fire. (I’m glad we don’t own Valeant!)

In addition to management turmoil, Perrigo’s business has underperformed due to declining generic drug prices and weak growth from Omega, Perrigo’s European business. John Hendrickson, Perrigo’s new CEO, has worked at the company for 27 years and has a strong operational background, which we believe will serve the company well. We increased our position in the stock, because we think it’s an absolute bargain, and it should provide handsome returns in the future.

Gilead Sciences saw its stock sink 9.2% from $91.86 to $83.42, cutting 47 basis points off the Fund’s return. Gilead is a research-driven biopharmaceutical company focused on producing innovative treatments for infectious diseases like HIV/AIDS and hepatitis C. Increased competition in the hepatitis C therapy market and health-insurers moving some patients away from Gilead’s medicine hurt earnings and caused the stock price to move lower. Gilead is a great company with a proven track record of innovation, so we expect more new products from the company, which should move the stock much higher.

As interest rates dropped in the second quarter, Charles Schwab dropped 9.7% from $28.02 to $25.31, knocking 41 basis points off the Fund’s return. Many people think of Schwab as being a discount broker, executing trades for stocks, bonds and mutual funds, but, in reality, it is a bank that is very sensitive to interest rates. Although Schwab started life as a discount broker, it soon changed into something else, as it started investing customer’s cash balances, organized money market funds, and finally established its own bank. Soon, Schwab earned much more in interest than it did brokering securities. Under normal circumstances, the company earns more than half its income from interest, although at the present time, it only earns 45% of its revenue from interest charges. (That will soon go well over 50% when interest rates move higher to more normal levels.) Because interest rates are so low now, Schwab’s earnings are depressed, and the stock has moved much lower. However, at some point, interest rates will move much higher, and when they do, we believe Schwab’s stock will take off.

Autodesk, the leading software provider for architects, engineers and designers, slumped 7.2% from $58.31 to $54.14, slicing 34 basis points off the NAV. The stock fell after the company reported weaker than expected earnings, and investors were worried that slowing global construction activity could curtail demand for the company’s design software. Another issue is that the company’s shift to a subscription model dampens revenue, since sales are no longer recorded up-front, but spread out over the period of the licensing contract. This makes revenue figures look lower in the short-run, but at some point, subscription revenue will catch up and sales will start growing again. When this happens, the stock should move much higher.

Despite all the bad news, two stocks pushed us over the top, so we could have a positive quarter. Micron Technology added 158 basis points to the Fund’s return, as its stock rose 31.4% from $10.47 to $13.76. The company makes specialized semiconductor memory chips called dynamic random access memory chips (known as DRAMs) that go into personal computers and other technology products. DRAMs are commodity chips, so their pricing is very volatile, going up sharply when demand is high and dropping suddenly when demand falls off. To play this cycle, an investor has to buy near the bottom and sell near the top, which we did, since our average cost is only $10.80. Right now, demand is growing faster than supply, so prices should move higher, but there will be a lot of bumps in the road, as the stock price moves up and down. Despite these zigs and zags, we believe the price should move much higher, so we’re holding on for a bumpy ride. Although we don’t want most of our stocks to be this volatile, we’re prepared to suffer a few bumps in the road if we get to the right destination.

Applied Materials makes equipment for use in manufacturing semiconductors, and it boosted the Fund’s return by 89 basis points, as its stock climbed 13.2% from $21.18 to $23.97. The company has now had two solid quarters of good performance, and the current outlook is bright, as new orders keep coming in – especially from China.

Outlook and Strategy

The big news in the investment world is that Great Britain has voted to leave the European Union (EU) or “Brexit” for short. I was quite surprised, to put it mildly, that they voted to leave. Everything pointed to the economic advantages of staying as part of Europe. London is now the financial capital of Europe, and one of the principal financial capitals of the world. Post-Brexit, there is a serious question of whether or not it can retain this status. Already, Dublin, Paris, Frankfurt, Berlin and Amsterdam are looking to take London’s financial business, arguing that they are better placed than London, since they are all in the EU. I tend to agree that Brexit will have a negative effect on London, but it’s too soon to know how much damage it will do to London’s status as a financial capital. I keep thinking that the British will have second thoughts and want to stay, but right now, there doesn’t seem to be any organized movement to hold another election. Both Scotland and Northern Ireland voted to remain in the EU, so I wonder if those entities will petition for another vote, either to allow them to leave the UK or to keep the UK in the EU.

I think most of us can agree that Brexit is not good for the British or the Europeans. At least in the short-run, it will have a negative effect on their economy. The question we have to ask ourselves is how much spill-over effect there will be on the United States, on our economy and on our stock market. The U.S. market moved straight down at an alarming pace after the Brexit vote, then in a big surprise, it came right back to end up almost where it started. I’m not sure what that was telling us, but it sure was confusing.

My own view is that Brexit will be a somewhat negative factor for our stock market and our economy. Because the European economy will be weaker, they will buy less from us, and this will hurt demand and production in America. Also, I suspect the pound and the euro will continue to decline, which will make our exports more costly in Europe and this will be a negative for our economy. Already, the pound has dropped around $1.30 compared to a range that had been just under $1.50. That’s a big drop. The euro hasn’t gone down as much, but I suspect there will be weakness in the euro as time goes on.

Although I’m somewhat pessimistic in terms of the short-run, I’m not going to sell off all our stocks and go to cash. The U.S. economy is in reasonably good shape now with good consumer demand and unemployment down to 5%. I think there will be some headwinds, but I have confidence that the U.S. economy will ultimately pull out of any tailspin that besets us. Unfortunately, I’m not too confident for the prospects in the UK and the EU. I think they’re in for some difficult times.

My view of the stock market is that it will be flat to somewhat down – at least for the next six months. However, we don’t practice market-timing at Parnassus, so we won’t be selling off stocks in hopes of buying them back again at a later date at a lower price. Somehow, I don’t think it’s possible to pull that off on a consistent basis. For example, look at what happened to

PARNASSUS FUNDS Semiannual Report  •  2016

the stock market right after the Brexit vote – a big move down after the vote, then a surprising recovery in only a few days’ time. In the short-run, the stock market is not very rational, even though it tends to be a good indicator of value over a longer period of time. Our policy will be to hang on to the stocks we own, since we bought good companies at good prices, and we hope they will be able to weather whatever storm is brewing because of the Brexit affair.

PARNASSUS MID CAP FUND

Ticker: Investor Shares - PARMX

Ticker: Institutional Shares - PFPMX

As of June 30, 2016, the NAV of the Parnassus Mid Cap Fund-Investor Shares was $27.73, so the total return for the quarter was a gain of 4.96%. This compares to a gain of 3.18% for the Russell Midcap Index (“Russell”) and a gain of 2.07% for the Lipper Mid-Cap Core Average, which represents the average mid-cap core funds followed by Lipper (“Lipper average”). For the first half of 2016, the Parnassus Mid Cap Fund – Investor Shares is also ahead of its benchmarks, posting a gain of 8.49% compared to a return of 5.50% for the Russell and 3.63% for the Lipper average.

Below is a table comparing the Parnassus Mid Cap Fund with the Russell and the Lipper average for the one-, three-, five- and ten-year periods. We are proud that the Fund is beating its benchmarks for each of these periods.

This agreement will not be terminated prior to May 1, 2017, and may be continued indefinitely by the Adviser on a year-to-year basis.

Second Quarter Review

Mid-cap stocks gained steadily throughout the quarter, until Great Britain’s vote to exit the European Union triggered a 6.1% market drop during the last week of June. The panic was short-lived, and within a few days the Russell recovered to preserve a healthy 3.2% gain for the quarter. The Fund did even better than its benchmarks, beating the Russell by 178 basis points (one basis point is equal to 0.01% or one one-hundredth of a percent) and the Lipper average by 289 basis points. From an allocation perspective, the Fund benefitted from having an underweight position in consumer discretionary stocks, the worst-performing sector in the benchmark. As usual though, our stock selection was the main driver of the Fund’s performance relative to the index.

Three stocks took more than 20 basis points from the Fund’s return. The worst performer was Perrigo, the leading producer of store-brand generic drugs. The stock sank 29.1% from $127.93 to $90.67, cutting 118 basis points from the Fund’s return. The shares plummeted in April after longtime CEO Joe Papa resigned to become the CEO of Valeant Pharmaceuticals. At the same time, Perrigo lowered its 2016 financial guidance for the second time this year. The company has suffered recently from declining generic drug prices and sluggish growth at Omega, its recently acquired European business.

Motorola Solutions, a provider of communications services and networks for public safety workers, sliced 33 basis points from the Fund’s return as its stock fell 12.9% from $75.70 to $65.97. Just last quarter, investors cheered the company’s acquisition of Airwave, Great Britain’s public safety communications network. Those cheers, however, turned to boos, when the British voted to leave the

17

PARNASSUS FUNDS Semiannual Report  •  2016

EU. Investor sentiment soured even further as regulators initiated a review of the deal to ensure it won’t suppress competition. The stock moved lower in late June, after Great Britain voted to leave the European Union, raising growth and currency concerns. We continue to believe that the Airwave deal will be accretive to corporate earnings in the next few years. On a positive note, the deal was cleared by regulators after the quarter ended, and we think Britain may actually need to increase its spending on public safety now that it’s left the European Union.

Axalta, the largest player in the global vehicle coatings market, fell 9.1% from $29.20 to $26.53, slicing 23 basis points from the Fund’s return. The company missed earnings expectations, as robust demand for the company’s auto refinishing products was more than offset by higher expenses, weak volumes in its commercial transportation coatings business and currency headwinds. We added to our position on this weakness, because we believe Axalta has a long runway for growth, paved by favorable secular trends and operating margin expansion.

Three stocks added more than 50 basis points to the Fund’s return this quarter. The best performer was Insperity, a provider of human resource services to small- and mid-sized businesses. The stock surged 49.3% from $51.73 to $77.23, adding 157 basis points to the Fund’s return. Encouraged by activist investor Starboard, Insperity management has been posting excellent results for some time now. This most recent quarter was no exception, as earnings grew almost 90% year-over-year, driven by strong new sales, better client retention, margin improvement, a lower tax rate and a lower share count. We trimmed our position as the stock hit an all-time high, but we continue to see upside as the company executes on its growth plan.

MDU Resources, a diversified conglomerate with operations in electric and gas utilities, construction materials and services and pipelines, added 67 basis points to the Fund’s return, as its stock rose 23.3% from $19.46 to $24.00. The stock rose after the company delivered earnings ahead of expectations, driven by an increase in bookings in its construction business and higher sales volumes in its natural gas distribution and electric businesses. The company also announced the sale of its refining business to Tesoro Corporation. We view this as a positive development, since the segment was a significant drag on earnings and distracted management from the company’s core businesses. We continue to see upside in the stock, as the company benefits from a robust construction backlog and further utility rate hikes.

Iron Mountain, the nation’s largest document storage company, climbed 17.5% from $33.91 to $39.83, adding 57 basis points to the Fund’s return. During the quarter, Iron Mountain made progress on its merger with Australian-based Recall, a transaction that combines the top two players in the global document storage industry. We think this deal positions Iron Mountain to accelerate revenue growth, as the smaller Recall has historically grown sales faster than Iron Mountain. Another positive is that Recall has a relatively lower debt load, so the combined entity will have a more conservative balance sheet than stand-alone Iron Mountain.

Outlook and Strategy

The Russell reached another all-time high during the quarter and is now up a staggering 270% since the March 2009 low. As we continue in the

Semiannual Report  •  2016 PARNASSUS FUNDS

eighth year of the bull market, mid-cap stocks have climbed to almost 18 times forward earnings estimates. This is much higher than the 15 times multiple at which the Russell was trading in 2009.

The Fund’s overall positioning didn’t change much during the quarter. Our largest concentration of stocks at the quarter-end was in the industrial sector. While the overweight allocation is less than it has been in previous quarters, we are still seeing good values in this area. Within this sector, we own a lot of business services companies, such as Waste Management and Insperity, which have stable balance sheets, secular growth and margin improvement opportunities. These businesses should have less downside than many of their industrial peers in the event of a correction.

We continue to own fewer energy and financial stocks than the benchmarks, because we’re unsure where oil prices and interest rates are heading, and the range of outcomes is unusually wide. In that spirit, compared to the Russell, the Fund also has fewer consumer discretionary stocks, which tend to be more volatile than the rest of the index. In fact, consumer discretionary stocks are the worst performers in the Russell so far in 2016, with even some of the highest quality names slipping into bargain territory.

During the quarter, we took advantage of the consumer sector weakness and initiated a position in Hanesbrands, Inc., a leading manufacturer of underwear and T-shirts with household brands including Hanes, Champion, Playtex and Maidenform. The stock dropped 25% from its 52-week high, as demand from its retail partners slowed due to unusual weather patterns and sluggish store traffic. We believe the company has sustainable competitive advantages due to its global brand and manufacturing scale, enabling the company to consistently generate high returns on invested capital and significant free cash flow. At 11 times forward earnings estimates, the stock is a relative bargain.

As we enter the third quarter, investors are asking many questions about the British vote to exit the European Union. We have limited exposure to that region, as less than 5% of our companies’ combined revenues comes from the United Kingdom and continental Europe.

We’re pleased that our strategy is providing excellent results to shareholders. The Fund seeks to own high-quality businesses at good prices that can grow intrinsic value faster than our benchmarks over the long-term. We are confident that the Fund should outperform the market over the long-term by participating in up markets, providing downside protection in bear markets and avoiding permanent capital losses in severe market corrections.

Thank you for your investment in the Parnassus Mid Cap Fund.

As of June 30, 2016, the net asset value (“NAV”) of the Parnassus Asia Fund–Investor Shares was $15.00, so the Fund gained 4.24% in the second quarter. This compares to a gain of 0.77% for MSCI AC Asia Pacific Index (“MSCI Index”) and a gain of 2.45% for the Lipper Asia Pacific Region Average, which represents the average return of the Asia Pacific Region funds followed by Lipper (“Lipper average”). As you can see, we trounced both of our indexes this quarter, primarily because our investments in certain technology companies appreciated in value.

The average annual total return for the Parnassus Asia Fund-Institutional Shares from commencement (April 30, 2015) was -13.81%. Performance shown prior to the inception of the Institutional Shares reflects the performance of the Parnassus Asia Fund-Investor Shares and includes expenses that are not applicable to and are higher than those of the Institutional Shares. The performance of the Institutional Shares differs from that shown for the Investor Shares to the extent that the classes do not have the same expenses. 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 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 MSCI AC Asia Pacific Index is an unmanaged index of Asian stock markets, 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.

The Fund invests primarily in non-U.S. securities. Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market or economic developments and can perform differently from the U.S. market.

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, 2016, Parnassus Investments has contractually agreed to limit the total operating expenses to 1.25% of net assets for the Parnassus Asia Fund-Investor Shares and to 1.22% of net assets for the Parnassus Asia Fund-Institutional Shares. This agreement will not be terminated prior to May 1, 2017 and may be continued indefinitely by the Adviser on a year-to-year basis.

made a strong comeback this year and remain ahead of both of our benchmarks since inception. Indeed, in the three-plus years since the Fund’s launch on April 30, 2013, we beat the MSCI Index by 62 basis points and beat the Lipper average by 55 basis points.

Company Analysis

The Asia Fund’s strong performance during the quarter was attributable to our investments in certain high-technology stocks, which rebounded significantly compared to the first quarter. Five companies contributed 40 basis points or more to the Fund’s return this quarter, while four subtracted 40 basis points or more from the return.

Our worst performer was Topcon Corporation, which reduced the Fund’s return by 90 basis points as its stock price fell 25.1% from $13.19 to $9.89. The Japanese company is a leading manufacturer of high-precision equipment used in the infrastructure, agriculture and healthcare industries globally. The company’s largest segment, Topcon Positioning, sells products and systems that rely on GPS to make farming and construction work cheaper and easier through the use of automation and data. Severely depressed crop prices from corn, soybean and wheat weakened the financial position of Topcon’s agricultural customers, who bought less of Topcon’s efficiency-enhancing equipment. Longer-term though, the company’s predominant technology, established distribution and global presence should allow Topcon to maintain and grow share in the under-penetrated markets that it serves.

Lenovo decreased the Fund’s return by 67 basis points, as its stock price slumped 22.0% from $0.78 to $0.61. (We own the Hong Kong–listed shares, which are more liquid than the U.S.-listed ADRs; one ADR is equal to 20 shares with a value of $12.04 at quarter-end.) The maker of personal

20

computers and other technology products is the number-one brand in China and the largest PC manufacturer in the world. Despite Lenovo’s strong 20% worldwide market share, PC shipments declined due to global economic concerns, delayed upgrades to Windows 10, and the continued shift to mobile devices. In smartphones, Lenovo also fell from its number three position behind Samsung and Apple to fifth place, behind Huawei and other new entrants. Finally, Google announced it would

sell a majority of the Lenovo shares it received after it sold Motorola Mobility to Lenovo in 2014. Nevertheless, the company’s low current valuation and attractive 4% dividend yield suggest limited downside.

Perrigo, the leading producer of store-brand generic drugs, cut 56 basis points from the Fund’s return, as its stock sank 9.1% from our cost basis of $99.70 to $90.67. Shares plummeted in April after longtime CEO Joe Papa resigned to become the CEO at Valeant Pharmaceuticals, and Perrigo lowered its 2016 guidance for the second time this year. The business has underperformed due to declining generic drug prices and weak growth from Omega, Perrigo’s European business. While we think John Hendrickson, Perrigo’s new CEO, is the right person for the job given his strong operational background, we’re continuing to monitor the drug pricing environment.

As its name implies, Air Lease purchases aircraft and leases them to airlines, and its stock fell 16.6% from $32.12 to $26.78, trimming 44 basis points from the Fund’s return. The company reported better than expected earnings and held an upbeat investor day, where Air Lease highlighted its expectation to double its aircraft fleet over the next five years. Nonetheless, the stock dropped due to concerns that slowing global growth could negatively impact air traffic. Despite this concern, we believe that long-term air travel demand will remain robust and that airlines will continue to utilize the financial flexibility offered by leasing.

Turning to our winners, Hermes Microvision was the Parnassus Asia Fund’s best performer this quarter, adding 161 basis points to the Fund’s return, as its stock price soared 45.1% from $28.58 to $41.48. The Taiwan-based company develops and markets electron beam (E-beam) inspection tools for semiconductor manufacturers for use in testing for defects in silicon wafers. Hermes’ stock price surged after Dutch company ASML, the largest supplier of photolithography systems in the world, announced that it would acquire all of Hermes’ outstanding shares for U.S. $3.1 billion in cash. ASML intends to use Hermes’ E-beam technology to support the ramp of its next-generation Extreme Ultraviolet (EUV) tool, which is set to be used for volume production of semiconductors starting in 2018. The deal is expected to close at the end of this year, so Hermes’ stock should have further room to run.

Portfolio characteristics and holdings are subject to change periodically.

Micron Technology added 125 basis points to the Fund’s return, as its stock rose 31.4% from $10.47 to $13.76. Micron makes semiconductor memory chips, and its stock jumped as prices for dynamic random access memory (also known as DRAM) increased in June for the first time in two years. Just last quarter Micron was our biggest loser, as DRAM prices continued their fall, and investors fretted that there was no end in sight. Since production capacity is growing at a slower rate than demand, we were confident DRAM prices would eventually stabilize, but we didn’t know precisely when. While we were early with our initial investment, we added to our position on the weakness and we’re happy our conviction is beginning to pay off. We expect demand growth to continue, as computing becomes even more integral to the global economy, which should push Micron’s earnings and its stock higher.

Semiconductor-equipment manufacturer Applied Materials added 62 basis points to the Fund’s return, as its stock increased 13.2% from $21.18 to $23.97. Building off last quarter’s solid performance, the company continued to execute well, reaching

21

PARNASSUS FUNDS Semiannual Report  •  2016

an all-time high in order volume in China. The sustained outperformance and positive financial outlook has provided investors with increased confidence in the long-term trajectory of the business.

SITC International Holdings increased the Fund’s return by 46 basis points, as its stock climbed 6.4% from 49¢ to 53¢. The Hong Kong-based, integrated shipping-and-logistics company has operations that span Mainland China, Japan, Southeast Asia and internationally, making it the 10^th largest container shipping operator in Asia. Despite the challenging macroeconomic environment, SITC maintained high profit margins through efficient cost management and by offering its

clients value-added services such as land logistics and integrated door-to-door service. The company was also designated a Shanghai-Hong Kong Connect stock in March by representatives of both cities’ exchanges. Given the expanded trading pool, more Chinese and international investors were able to discover SITC’s strong fundamentals and shareholder returns, and they bought more of SITC’s stock.

The stock price of Rakuten advanced 12.4% from $9.65 to $10.85, adding 44 basis points to the Fund’s return. Based in Japan, Rakuten is an international online shopping mall with tens of thousands of merchants; it is also a major player in online financial services, including securities brokerage and credit cards. Earlier in the year, Rakuten’s profit margins weakened, as it invested in promotions and expanded its loyalty points program to fend off intensified competition from Amazon and Yahoo. Now, those moves appear to be bearing fruit as Rakuten usage is increasing among new and formerly dormant users. Investors reacted positively to management’s turn-around efforts including the exit of unprofitable overseas business units, so the stock price moved higher.

Outlook and Strategy

Asian markets fluctuated wildly again this quarter, but ultimately finished the period close to where they started. In effect, a dollar invested in the entire universe of Asian stocks would have achieved returns no better than a dollar of cash over the last three months. That is a sobering thought, given the macroeconomic uncertainty stock investors had to endure—everything from the slowing Chinese economy, the runaway Japanese yen and the surprise British vote to secede from the European Union. Despite this, the Parnassus Asia Fund performed much better than the universe of Asian stocks represented by the MSCI Index. The main reason for our outperformance was our investments in technology companies as described in the company analysis section above. Another reason was our long-standing underweight in Japan.

After years of government intervention to prop up prices, the Japanese stock market has been turned on its head. Instead of economic fundamentals, the market now reacts primarily to the proclamations and actions of the country’s central bank. When two major earthquakes disrupted manufacturing supply chains in southern Japan, for instance, stocks actually rose on expectations that the government would expand its stimulus measures. The market later slumped after a planned consumption tax increase was delayed, and uncertainty over the future of Britain and the EU stoked a rally in the Japanese yen, hurting exports. By the end of the quarter, Japan was the worst performing market in Asia in constant currency.

As mentioned, the Fund has less money invested in Japan compared to the benchmark. We chose not to participate in the Japanese market’s dysfunction, so we avoided the market’s sell-off since the end of last year. Instead, we found better value in defensive or inexpensive U.S. companies with exposure to Asia. As stock-pickers first and foremost, we are not beholden to any one market or set of markets. With the Parnassus Asia Fund, we are constantly searching the world for high-quality companies that are trading at a discount and, we try to buy them wherever we can find them. We believe this is the foundation for successful long-term investing and hope you do too.

PARNASSUS FIXED INCOME FUND

Ticker: Investor Shares - PRFIX

Ticker: Institutional Shares - PFPLX

As of June 30, 2016, the NAV of the Parnassus Fixed Income Fund – Investor Shares was $16.98, producing a gain for the quarter of 1.94% (including dividends). This compares to a gain of 2.21% for the Barclays U.S. Aggregate Bond Index (“Barclays Aggregate Index”) and a gain of 2.31% for the Lipper Core Bond Funds Average, which represents the average return of the core bond funds followed by Lipper (“Lipper average”). For the first half of 2016, the Fund posted a gain of 4.34%, as compared to a gain of 5.31% for the Barclays Aggregate Index and a gain of 5.02% for the Lipper average.

Below is a table comparing the performance of the Fund with that of the Barclays Aggregate Index and the Lipper average. Average annual total returns are for the one-, three-, five- and ten-year periods. For June 30, the 30-day subsidized SEC yield was 1.74%, and the unsubsidized SEC yield was 1.59%.

Quarter in Review

It was a dramatic quarter for fixed income markets, as Great Britain’s unexpected decision to leave the European Union pushed Treasury yields to all-time lows. When markets are volatile, investors pile into Treasuries as they are viewed as a very safe asset, pushing prices higher and yields lower. The Parnassus Fixed Income Fund is conservatively positioned, which means it is less impacted by interest rate movements, so it did not gain as much when interest rates fell. This is the key reason why the Fund’s gain slightly lagged the Barclays Aggregate Index.

Convertible bonds issued by Exelixis, a biotechnology company, were our top performers in the quarter, gaining 49.9%, and adding 13 basis points to the total return. The bonds went down last quarter as biotechnology companies fell out of favor. This quarter, the bonds jumped to new highs as investors refocused on the company’s novel cancer treatments and the upcoming commercialization of two therapies later this year. I expect the bonds to continue to perform well as these treatments are brought to market and in-process drug trials move forward.

Corporate bonds issued by Juniper Networks, Pentair and Discover Financial contributed more than 5 basis points each. Juniper Networks’ bonds gained 4.99% and added 8 basis points to the total return in the quarter. The bonds benefitted from improved sentiment on the company as new product launches bolstered expectations.

Pentair’s bonds gained 2.66% in the quarter and added 7 basis points to the total return. The company’s bonds benefitted from management’s strong focus on improving the balance sheet. Pentair’s acquisition of ERICO last fall pushed its

24

Semiannual Report  •  2016 PARNASSUS FUNDS

leverage well above the normal range, leading S&P to downgrade the company’s credit rating last quarter. Since that time, management has made deleveraging a focus of the company, and I expect the company’s bonds to continue to recover.

Finally, Discover Financial’s bonds gained 4.85% and added 6 basis points to the total return. After a rocky start to the year for most financial bonds, sentiment improved for Discover’s credit quality after management reported solid earnings and a positive stress-test report from the Federal Reserve.

The Fund’s only bonds that were down meaningfully in the quarter were Progressive issues. The insurance company’s bonds lost 2.51% and shaved 2 basis points from the total return. Major storms in Texas in April caused significant hail damage to homes and cars. This led to losses in Progressive’s legacy auto insurance division, as policy holders filed a large volume of claims. The storms also led to losses in Progressive’s new home insurance division.

Outlook and Strategy

The U.S. bond market, and the Treasury market in particular, have become increasingly influenced by international events. Growth rebounded this quarter and consumer spending was particularly strong, which normally would have pushed yields higher. Instead, yields fell because of the uncertainty created by Great Britain’s decision to leave the European Union. In this environment, where U.S. data is overlooked and the focus is on international events, it’s especially difficult to forecast the upcoming direction of interest rates.

Recognizing this, there are two primary ways the Parnassus Fixed Income Fund is positioned to weather continued volatility. First, the Fund’s duration is relatively short. Duration is a measure of interest rate sensitivity, and having a short duration means the Fund is less sensitive to interest rate movements. While this means the Fund does not gain as much when interest rates decline, it also helps insulate the Fund from losses if interest rates rise.

Second, I increased the Fund’s allocation to corporate bonds. The corporate bond portfolio best utilizes the strengths of the Parnassus research team and provides opportunities for fundamental credit research and bond-picking. Many bonds held in the Parnassus Fixed Income Fund were issued by companies that are also held in the Parnassus equity funds. In addition to having solid growth prospects and competitive advantages, these companies also favor strong balance sheets, making them good bond investments. I added several new bonds to the Fund this quarter, including those issued by Whole Foods Markets, National Oilwell Varco and Masco Corp. These bonds all yield above 3%, which is much higher than the market average, and they are improving the current income of the Fund.

Thank you for your investment in the Parnassus Fixed Income Fund.

Responsible Investing Notes

By: Milton Moskowitz

A long-term Parnassus holding, San Diego-based WD-40 is probably the smallest company ever to appear in our portfolios. It has fewer than 450 employees, who generate annual sales of $400 million. That little spray can of WD-40 can be found in most American homes. If you have a hinge that’s squeaking, just spray it with WD-40. The company continually asks customers to come up with new uses. Result: it now has a list of 2,000 uses.

Brambles, one of Australia’s largest and oldest companies, has annual revenues of $5.4 billion. It was founded in 1875 by Walter Brambles, an 18-year-old butcher. Today, the company ranks as one of the world’s largest suppliers of pallets, crates and shipping containers, a logical business for a company born and still located in Newcastle, a beach town in New South Wales, 100 miles north of Sydney. A holding of the Parnassus Asia Fund, the company employs 14,000 people – and those who work at headquarters enjoy the flourishing art scene in Newcastle. It’s also a major destination for surfers. Many people first heard of Newcastle in 2011 when Lonely Planet named it one of the top 10 cities to live.

The annual Fortune 500 issue is out, featuring the usual suspects. Ranking companies by their 2015 sales, this is the bible for big corporations. Number one for the fourth consecutive year is Walmart, with sales of $482 billion. In second place again is Exxon Mobil, even though they were clobbered by a 35% drop in sales. “Three Parnassus portfolio companies, Apple, CVS Health and McKesson, made the Top 10 list.” Apple moved up from 5^th to 3^rd, and CVS advancing from 10^th to 7^th. Others in the Top 10 list include Warren Buffet’s company, Berkshire Hathaway (4^th), United Health Group (6^th), General Motors (8^th), Ford (9^th) and AT&T (10^th).

To make the list this year, a company had to register sales of at least $5.13 billion. The company in that 500 slot is Burlington Stores, headquartered in Burlington, New Jersey. To reach the next Parnassus Funds holding after CVS, one has to scroll down to 21, a position filled by Cardinal Health. Other Parnassus companies with high rankings (Top 50) are: IBM (31), Procter & Gamble (34) and Alphabet-Google (39). Nine other portfolio companies (and their rankings) are: Intel (52), Walt Disney (57), United Parcel Service (47), Cisco (54), Mondelez (94), Qualcomm (110), Danaher (133), Cummins (148) and Whole Foods (181).

Many companies became embroiled in the controversy over North Carolina’s new law denying transgenders the right to use bathrooms corresponding to their new identities. The state legislature ruled that everyone had to use bathrooms corresponding to his or her identity at birth. In other words, a woman who changes her identity to a man cannot then use the men’s room. I can’t believe I am writing this, but grown men and women are spending their time debating this issue. One report said that one million customers had signed a petition saying they would no longer shop at stores like Target, which are opposing the new law. On the other hand, Bruce Springsteen and Pearl Jam canceled concerts that had been scheduled for North Carolina, and Bank of America, the state’s largest employer, weighed in against the law. Deutsche Bank said it would freeze plans to add 250 North Carolina jobs while the law was in place, and CEOs of more than 100 companies signed a letter decrying the law. Signers included CEOs of salesforce.com, Intel, IBM and Facebook. The Justice Department has also weighed in on the side of the transgenders. Speaking to shareholders at Target’s annual meeting earlier this year, CEO Brian Cornell reminded them of the company’s long history of diversity and inclusivity.

Measured by location, New York State remains the No. 1 location for Fortune 500 companies, hosting 55 of them. Texas and California tied for second place, each with 51. If you ranked companies by number of employees, the Top 10 would look like this:

Walmart: 2.3 million

Yum Brands: 505,000

Kroger: 431,000

McDonalds: 420,000

IBM: 411,798

Home Depot: 385,000

26

Semiannual Report  •  2016 PARNASSUS FUNDS

United Parcel Service: 341,240

Target: 341,000

Berkshire Hathaway: 331,000

General Electric: 330,000

Diversity continued to be an elusive goal. In 2015, there were five African American CEOs; now there are four. Last year’s list showed 24 female CEOs; now there are 21.

One final note: Facebook is not in any of the Parnassus Fund portfolios, but it’s worth looking at for some remarkable attributes. The social media giant jumped 85 spots on the Fortune 500 list to land in 157^th place, sandwiched between construction giant Aecom and electronics supplier Jabil Circuit. And here is the triple play:

Mark Zuckerberg, founder and CEO, reduced his salary to $1 a year.

Last year, when Zuckerberg’s wife, Priscilla Chang, gave birth to their first child, the Facebook CEO took a paternity leave of two months to be with his daughter, Max.

Zuckerberg studied hard to become fluent in Mandarin. Last year, when the president of China, Xi Jinping, visited Facebook, Zuckerberg was able to conduct the entire meeting in Mandarin.

So this is not just a geek in a hoodie.

Fund Expenses (unaudited)

As a shareholder of the Funds, you incur ongoing costs, which include portfolio management fees, administrative fees, shareholder reports, and other fund expenses. The Funds do not charge transaction fees, so you do not incur transaction costs such as sales charges (loads) on purchase payments, reinvested dividends, or other distributions, redemption fees, and exchange fees. The information on this page is intended to help you understand your ongoing costs of investing in the Funds and to compare these costs with the ongoing costs of investing in other mutual funds.

The following example is based on an investment of $1,000 invested at the beginning of the most recent six-month period and held for the period of January 1, 2016 through June 30, 2016.

Actual Expenses

In the example below, the first line for each Fund provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of each Fund provides information about hypothetical account values and hypothetical expenses based on the Fund’s expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. You may compare the ongoing costs of investing in the Fund with other mutual funds by comparing this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Please note that the expenses shown in the table are meant to highlight only your ongoing costs in these Funds. Therefore, the second line of each Fund is useful in comparing only ongoing costs and will not help you determine the relative total costs of owning other mutual funds, which may include transactional costs such as loads.

* Expenses are calculated using the Funds’ annualized expense ratios, which represent ongoing expense as a percentage of net assets for the six months ended June 30, 2016. Expenses are calculated by multiplying the annualized expense ratio by the average account value of the period; then multiplying the result by the number of days in the most recent one-half year period (182); and then dividing that result by the number of days in the current fiscal year (366). Expense ratios for the most recent half year may differ from expense ratios based on one-year data in the financial highlights.

Semiannual Report  •  2016 PARNASSUS FUNDS

Notes to Financial Statements

1. Organization

The Parnassus Funds are comprised of two Trusts, the Parnassus Funds trust and the Parnassus Income Funds trust (collectively the “Trusts”), organized as Massachusetts Business Trusts registered under the Investment Company Act of 1940 as diversified, open-end investment management companies, and are comprised of six separate funds (collectively the “Funds”). The Parnassus Funds trust includes the Parnassus Fund, which commenced operations on December 27, 1984, the Parnassus Endeavor Fund and the Parnassus Mid Cap Fund, both of which commenced operations on April 29, 2005, and the Parnassus Asia Fund, which commenced operations on April 30, 2013. The Parnassus Income Funds trust includes the Parnassus Core Equity Fund and the Parnassus Fixed Income Fund, both of which commenced operations on August 31, 1992. Each Fund has distinct investment objectives. In general, each of the Funds seeks long-term capital appreciation. Prior to May 1, 2014, the Parnassus Core Equity Fund was known as the Parnassus Equity Income Fund, and the Parnassus Endeavor Fund was known as the Parnassus Workplace Fund.

On April 24, 2015, the Parnassus Small Cap Fund merged into the Parnassus Mid Cap Fund.

The Parnassus Funds trust now includes the Parnassus Fund – Institutional Shares, the Parnassus Endeavor Fund – Institutional Shares, the Parnassus Mid Cap Fund – Institutional Shares and the Parnassus Asia Fund – Institutional Shares, which commenced operations on April 30, 2015. The Parnassus Income Funds trust now includes the Parnassus Fixed Income Fund – Institutional Shares, which commenced operations on April 30, 2015.

The Parnassus Fund, the Parnassus Endeavor Fund, the Parnassus Mid Cap Fund, the Parnassus Asia Fund and the Parnassus Fixed Income Fund were renamed to the Parnassus Fund – Investors Shares, the Parnassus Endeavor Fund – Investor Shares, the Parnassus Mid Cap Fund – Investor Shares, the Parnassus Asia Fund – Investor Shares and the Parnassus Fixed Income Fund – Investor Shares, respectively, on May 1 , 2015.

Reorganization: On February 17, 2015, the Board of Trustees of the Parnassus Mid Cap Fund (the “Mid Cap Fund”) and the Parnassus Small Cap Fund (the “Small Cap Fund”) approved the reorganization of the Small Cap Fund into Mid Cap Fund pursuant to which Mid Cap Fund acquired substantially all of the assets and substantially all of the liabilities of the Small Cap Fund in exchange for an equal aggregate value of newly-issued shares of the Mid Cap Fund.

Each shareholder of the Small Cap Fund received shares of the Mid Cap Fund in an amount equal to the aggregate net asset value of such shareholder’s Small Cap Fund shares, as determined at the close of business on April 24, 2015, less the costs of the Small Cap Fund’s reorganization.

The reorganization was accomplished by a tax-free exchange of shares of the Mid Cap Fund in the following amounts and at the following conversion ratios:

Small Cap’s Shares Prior to Reorganization	Conversion Ratio		Shares of Mid Cap Fund
12,550,658.318		0.826724		12,201,071.649

The Small Cap Fund’s net assets and composition of net assets on April 24, 2015, the date of the merger, were as follows:

Net Assets	Paid-in Capital		Accumulated Net Realized Gain		Net Unrealized Appreciation
$292,947,668	$	248,282,045	$	15,983,054	$	41,089,670

For financial reporting purposes, assets received and shares issued by the Mid Cap Fund were recorded at fair value. However, the cost basis of the investments received from the Small Cap Fund was carried forward to align ongoing reporting of the Mid Cap Fund’s realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes.

53

PARNASSUS FUNDS Semiannual Report  •  2016

Notes to Financial Statements (continued)

The aggregate net assets of the Mid Cap Fund immediately after the acquisition amounted to $637,425,434. The Small Cap Fund’s fair value and cost of investments prior to the reorganization were $293,945,479 and $252,855,808, respectively.

The purpose of this transaction was to combine two funds managed by Parnassus Investment, with the same or substantially similar (but not identical) investment objectives, investment policies, strategies, risks and restrictions. The reorganization was a tax-free event and was effective on April 27, 2015.

Assuming the acquisition had been completed on January 1, 2015, the beginning of the fiscal reporting period of the Mid Cap Fund, the pro forma results of operations for the period ended April 24, 2015, are as follows:

• Net investment income: $548,982

• Net realized and change in unrealized loss on investments: $(2,185,669)

• Net decrease in net assets resulting from operations: $(1,636,687)

Because the combined investment portfolios have been managed as a single integrated portfolio since the acquisition was completed, it is not practicable to separate the amounts of revenue and earnings of the Small Cap Fund that have been included in the Mid Cap Fund’s Statements of Operations since April 27, 2015. Reorganization costs incurred by the Mid Cap Fund in connection with the reorganization were paid by Parnassus Investments.

2. Significant Accounting Policies

Short-Term Securities

Short-term securities represent investments of excess cash and consist of time deposits, community development loans, certificates of deposit and money market funds.

Security Transactions and Related Investment Income and Expenses

Securities transactions are recorded on the date the securities are purchased or sold (trade date). Realized gains and losses on securities transactions are determined on the basis of first-in, first-out for both financial statement and federal income tax purposes. Dividend income is recognized on the ex-dividend date and interest income is recognized on an accrual basis. Discounts and premiums on securities purchased are amortized over the lives of the respective securities using the constant yield method, which approximates the interest method. Expenses are recorded on an accrual basis.

Class Allocations

Income, fees and expenses (other than class-specific fees and expenses) and realized and unrealized gains and losses are allocated daily among the various shares classes based on their relative net assets. Class-specific fees and expenses, such as distribution, administrative and shareholder services, are charged directly to the respective share class.

Dividends and Distributions to Shareholders

Dividends and distributions to shareholders are recorded on the ex-dividend date to shareholders of record on the record date. The Parnassus Core Equity Fund pays income dividends quarterly and capital-gain dividends annually. The Parnassus Fixed Income Fund pays income dividends monthly and capital-gain dividends annually. The other Funds pay income and capital-gain dividends annually.

Currency Translation

Assets and liabilities, including investment securities, denominated in currencies other than U.S. dollars are translated into U.S. dollars at the exchange rates supplied by the Funds’ pricing vendor on the valuation date. Purchases and sales of investment securities and income and expenses are translated into U.S. dollars at the exchange rates on the dates of such transactions. On the accompanying financial statements, the effects of changes in exchange rates on investment securities are included with the net realized gain or loss and net unrealized appreciation or depreciation on investments. The realized gain or loss and unrealized appreciation or depreciation resulting from all other transactions denominated in currencies other than U.S. dollars are disclosed separately.

3. Securities Valuations

Methods and Inputs

Equity securities that are listed or traded on a national securities exchange are stated at market value, based on recorded closing sales on the exchange or on the NASDAQ’s National Market official closing price. In the absence of a recorded sale, and for over-the-counter securities, equity securities are stated at the mean between the last recorded bid and asked prices. Long-term, fixed-income securities are valued each business day using prices based on procedures established by independent pricing services and approved by the Board of Trustees (the “Trustees”). Fixed-income securities with an active market are valued at the “bid” price where such quotes are readily available from brokers and dealers and are representative of the actual market for such securities. Other fixed-income securities experiencing a less active market are valued as determined by the pricing services based on methods which include consideration of trading in securities of comparable yield, quality, coupon, maturity and type, as well as indications as to values from dealers and other market data without exclusive reliance upon quoted prices or over-the-counter prices, since such valuations are believed to reflect more accurately the value of such securities. Investments in registered investment companies are valued at their net asset value.

Investments where market quotations are not readily available are priced at their fair value, in accordance with procedures established by the Trustees. These investments include certificates of deposit and community development loans. These investments carry interest rates ranging from 0.10% to 2.25% with maturities of one year or less. In determining fair value, the Trustees may consider a variety of information including, but not limited to, the following: price based upon a multiple of earnings or sales, fundamental analytical data and an evaluation of market conditions. A valuation adjustment is applied to certificates of deposit, community development loans and other community development investments as an estimate of potential penalties for early withdrawal.

The Funds follow Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosure, which defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Various inputs are used in determining the value of the Funds’ portfolio investments. These inputs are summarized in three levels, Level 1—unadjusted quoted prices in active markets for identical investments, Level 2—other significant observable inputs (including quoted prices for similar investments) and Level 3—significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

Securities Lending

The Parnassus Funds, with the exception of the Parnassus Asia Fund, have entered into an agreement with Brown Brothers Harriman & Co., dated July 29, 2009 (“Agreement”), to provide securities lending services to the Funds. Under this program, the proceeds (cash collateral) received from borrowers are used to invest in money market funds.

Under the Agreement, the borrowers pay the Funds negotiated lenders’ fees and the Funds receive cash collateral in an amount equal to 102% of the market value of loaned securities. The borrower of securities is at all times required to post cash collateral to the portfolio in an amount equal to 100% of the market value of the securities loaned based on the previous day’s market value of the securities loaned, marked-to-market daily. Any collateral shortfalls are adjusted the next business day. If the borrower defaults on its obligations to return the securities loaned because of insolvency or other reasons, the portfolio could experience delays and costs in recovering the securities loaned.

The agreement provides the right in the event of default for the non-defaulting party to liquidate the collateral and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, the Fund, as lender, would offset the market value of the collateral received against the market value of the securities loaned. When the value of the collateral is greater than that of the market value of the securities loaned, the lender is left with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of a counterparty’s bankruptcy or insolvency. Under the agreement, the borrower can resell or re-pledge the loaned securities, and the Funds can reinvest cash collateral, or, upon an event of default, resell or re-pledge the collateral.

The Funds retained beneficial ownership and all economic benefits in the securities they have loaned and continues to receive interest paid by the securities and payments equivalent to dividends, and to participate in any changes in their market value,

but does not have the proxy voting rights with respect to loaned securities. Each portfolio manager of the Funds has the responsibility to request that the securities lending agent call back securities which are out on loan to vote on material matters and it is the Funds’ policy that the portfolio managers vote on all material matters. However, the ability to timely recall shares for proxy voting purposes typically is not entirely within the control of the portfolio manager, the Funds or their securities lending agent. Under certain circumstances, the recall of shares in time for such shares to be voted may not be possible due to applicable proxy voting record dates and administrative considerations.

Income generated from securities lending is presented in the Statement of Operations. Cash collateral received by the Funds is reflected as an asset (securities purchased with cash collateral from securities lending) and the related liability (payable upon return of securities loaned) is presented in the Statement of Assets and Liabilities.

At June 30, 2016, the following tables are a summary of the Funds’ securities lending agreements by counterparty, which are subject to offset under the agreement:

¹  Collateral value of $18,110,070, $28,969,501 and $6,183,865 has been received in connection with securities lending agreements for Parnassus Fund, Parnassus Endeavor Fund and Parnassus Mid Cap Fund, respectively. Collateral received in excess of the value of the securities loaned from the individual counterparty is shown for financial reporting purposes in the fund financial statements.

Community Development Investment Programs

The Parnassus Funds may each invest up to 2% of their assets in community investments and community-development loan funds. Each of the Funds may invest in obligations issued by community loan funds at below-market interest rates if the projects financed have a positive social impact. Generally, there is no secondary market on loan funds and thus these are considered illiquid.

As part of our community development investment program, the Parnassus Core Equity Fund has entered into an agreement for fund investments through the Certificate of Deposit Account Registry Service (“CDARS”) network. The CDARS network allows members to place funds in time deposits with depository institutions whose accounts are insured by the Federal Deposit Insurance Corporation (“FDIC”). Provisions stipulate that participating institutions are FDIC insured, however, in the event of default or bankruptcy by any party to the agreement, the proceeds of the investment may be delayed or subject to legal proceedings and are subject to FDIC limits. While certain investments of the Funds may be bank deposits and may be covered by FDIC insurance, the Funds are themselves not covered by FDIC insurance.

56

Semiannual Report  •  2016 PARNASSUS FUNDS

Notes to Financial Statements (continued)

The Parnassus Core Equity Fund and the Parnassus Fixed Income Fund holds debt instruments issued by MicroVest Plus, LP, a microfinance limited partnership specializing in providing capital to international microfinance institutions (“MFI’s”) that extend credit to developing countries and the entrepreneurial poor. This instrument may be subject to political and foreign currency exchange risk not normally associated with domestic debt instruments. MicroVest Plus, LP’s investment in MFI’s can be affected by, among other factors, commodity prices, inflation, interest rates, taxation, social instability, and other political, economic or diplomatic developments in or affecting the various countries where MFI’s operate.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Subsequent Events

Management has evaluated the impact of all subsequent events on the Funds through the date the financial statements were issued and has determined that there were no subsequent events requiring adjustment to or additional disclosure in the financial statements.

4. Risk Factors

Investing in the Parnassus Funds may involve certain risks including, but not limited to the following:

Market Conditions

The prices of, and the income generated by, the common stocks and other securities held by the Funds may decline in response to certain events taking place around the world, including those directly involving the companies whose securities are owned by the Funds; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and commodity price fluctuations. Additionally, the values of, and the income generated by, most debt securities held by the Fund may be affected by changing interest rates and by changes in the effective maturities and credit ratings of these debt securities. The Funds’ investment adviser attempts to reduce these risks through diversification of the portfolio and ongoing credit analysis as well as by monitoring economic and legislative developments, but there can be no assurance that it will be successful at doing so. Investments in securities issued by entities based outside the U.S. may also be affected by currency controls; different accounting, auditing, financial reporting, and legal standards and practices; expropriation; changes in tax policy; greater market volatility; different securities market structures and higher transaction costs.

Investing Outside the U.S.

Securities of issuers domiciled outside the U.S., or with significant operations outside the U.S., may lose value because of political, social, economic or market developments or instability in the countries or regions in which the issuer operates. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Securities markets in certain countries may be more volatile and/or less liquid than those in the U.S. Investment outside the U.S. may also be subject to different settlement and accounting practices and different regulatory, legal and reporting standards, and may be more difficult to value, than those in the U.S. The risks of investing outside the U.S. may be heightened in connection with investments in emerging and developing countries.

Contractual Obligations

Under the Trusts’ organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Trusts. Additionally, the Trusts have a variety of indemnification obligations under contracts with its service providers. The Trusts’ maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Trusts that have not yet occurred.

5. Taxation and Distributions

Federal Income Taxes

The Trusts intend to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all taxable income to shareholders. Therefore, no federal income tax provision is required.

57

PARNASSUS FUNDS Semiannual Report  •  2016

Notes to Financial Statements (continued)

Income distributions and capital-gain distributions are determined in accordance with income tax regulations, which may differ from U.S. Generally Accepted Accounting Principles (“GAAP”).

The Funds follow ASC 740, Income Taxes, relating to uncertainty in income taxes and disclosures. ASC 740 establishes a minimum threshold for income tax benefits to be recognized in the financial statements. These tax benefits must meet a “more likely than not” threshold, which means that based on technical merits, they have a more than 50% likelihood of being sustained upon examination by the tax authority. Tax benefits meeting this threshold are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the tax authority. As of and during the year ended December 31, 2015, the Funds did not have a liability for any unrecognized tax benefits. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statement of Operations. During the year, the Funds did not incur interest or penalties. The Funds are not subject to examination by U.S. federal taxing authorities before 2013 or state taxing authorities before 2012.

Semiannual Report  •  2016 PARNASSUS FUNDS

Notes to Financial Statements (continued)

The following table reconciles the valuation of the Funds’ Level 3 investment securities and related transactions as of June 30, 2016:

	Parnassus Fund			Parnassus Core Equity Fund			Parnassus Fixed Income Fund
	Certificates of Deposit			Certificates of Deposit
	Community Development Loans			Community Development Loans			Community Development Loans
Balance as of December 31, 2015	$	2,817,292		$	11,635,643		$	2,381,967

Balance as of June 30, 2016	$	2,780,933		$	11,411,733		$	2,456,558

There were no significant transfers between Level 1, Level 2 and Level 3.

Quantitative information about Level 3 fair value measurement:

	Fair Value at June 30, 2016		Valuation Technique	Unobservable Input	Range (Weighted Average)
Parnassus Fund
Certificates of Deposit	$	2,298,992	Liquidity Discount	Discount for Lack of Marketability	4%
Community Development Loans	$	481,941	Liquidity Discount	Discount for Lack of Marketability	6%
				Probability of Default	6%
Parnassus Core Equity Fund
Certificates of Deposit	$	2,695,920	Liquidity Discount	Discount for Lack of Marketability	4%
Community Development Loans	$	8,715,813	Liquidity Discount	Discount for Lack of Marketability	6%
				Probability of Default	6%
Parnassus Fixed Income Fund
Community Development Loans	$	2,456,558	Liquidity Discount	Discount for Lack of Marketability	6%
				Probability of Default	6%

The significant unobservable inputs used in fair value measurement of the Fund’s Certificates of Deposits are a discount for lack of marketability. The significant unobservable inputs used in the fair value measurement of the Fund’s Community Development Loans are a discount for lack of marketability and a discount for the probability of default. Significant increases in any of these inputs in isolation would result in a lower fair value measurement. Generally, a change in the assumption used for probability of default should be accompanied by a directionally-similar change in the assumption used for the lack of marketability.

Certain foreign securities may be fair valued by independent pricing services if events occur between the time at which the market quotations are determined on the primary exchange and the close of trading on the NYSE. These events may affect the value of these securities and render market quotations unreliable. Such fair valuations are categorized as Level 2 investments. Foreign securities that are valued based on market quotations are categorized as Level 1 investments.

ADDITIONAL INFORMATION (unaudited)

Board of Trustees Consideration of Investment Advisory Agreements

Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”) requires that the Board of Trustees (the “Trustees”) of the Parnassus Funds trust and the Parnassus Income Funds trust (the “Trusts”) which collectively are known as the Parnassus Funds (the “Funds”), meet in person to review and consider the continuation of any investment advisory agreement. In this regard, the Trustees who are not “interested persons” of the Trusts, as defined in the 1940 Act, (the “Independent Trustees”) met in person on March 22, 2016 and reviewed and re-approved the Trusts’ investment advisory agreements with Parnassus Investments. The Independent Trustees were provided with relevant information by Parnassus Investments, as described below, and were assisted in their evaluation of the investment advisory agreements by independent legal counsel, from whom they received assistance and advice, including a written memorandum, regarding the legal standards applicable to the consideration of advisory arrangements and with whom they met separately from Parnassus Investments’ management. In addition, the Trustees consider matters bearing on the management of the Funds and other arrangements at regular meetings throughout the year, including reviews of investment results and performance data at each regular meeting and periodic presentations from Parnassus Investments. Prior to approving the continuation of the investment advisory agreements, the Independent Trustees considered:

• the nature, extent and quality of the services provided by Parnassus Investments;

• the degree to which the Parnassus Fund, the Parnassus Core Equity Fund, the Parnassus Endeavor Fund, the Parnassus Mid Cap Fund, the Parnassus Asia Fund and the Parnassus Fixed Income Fund are being managed in accordance with each Fund’s stated investment objective;

• the investment performance of the each of the Funds;

• the cost of the services to be provided and profits to be realized by Parnassus Investments from its relationship with each of the Funds;

• the extent to which economies of scale would be realized as each of the Funds grew and whether fee levels reflect these economies of scale;

• the expense ratio of each of the Funds; and

• the manner in which portfolio transactions for the Funds are conducted, including the use of soft dollars.

In considering the nature, extent and quality of the services provided by Parnassus Investments, the Independent Trustees reviewed written and oral reports prepared by Parnassus Investments describing the portfolio management, shareholder communication and servicing, prospective shareholder assistance and regulatory compliance services provided by Parnassus Investments to the Funds. The Independent Trustees also considered a written report prepared by Broadridge, an independent provider of investment company data, comparing aspects of the portfolio management services provided by Parnassus Investments to similar services provided to a universe of comparable mutual funds (“Universe”). The Independent Trustees considered the experience of senior management and the qualifications, tenure, background and responsibilities of the portfolio managers primarily responsible for the day-to-day portfolio management of the Funds. The Independent Trustees evaluated the ability of Parnassus Investments, based on its financial condition, resources, reputation and other attributes to attract and retain qualified investment professionals, including research, advisory and supervisory personnel. The Independent Trustees further considered the compliance programs and compliance records of Parnassus Investments. In addition, the Independent Trustees took into account the administrative services provided to the Funds by Parnassus Investments. The Independent Trustees concluded that Parnassus Investments was providing essential services to the Funds.

The Independent Trustees compared the performance of each of the Funds to benchmark indices over various periods of time ending December 31, 2015 and to the Universe of comparable mutual funds as determined by Broadridge. The Independent Trustees noted that the performance for the Parnassus Fund, Parnassus Core Equity Fund, Parnassus Endeavor Fund and the Parnassus Mid Cap Fund was above the median of the Universe for all time periods under review. The Parnassus Asia Fund was below the median of the Universe for all time periods under review. The Independent Trustees further noted that the performance of the Parnassus Fixed Income Fund was below the median performance of the Universe for the two-, three-, four-, five and ten- year periods and was above the median for the one- year periods under review. The Independent Trustees concluded that the overall performance of the Funds warranted the continuation of the investment advisory agreements.

PARNASSUS FUNDS Semiannual Report  •  2016

ADDITIONAL INFORMATION (unaudited) (continued)

In concluding that the advisory fees payable by each of the Funds were reasonable, the Independent Trustees reviewed a report of the costs of services provided, and the profits realized, by Parnassus Investments from its relationship with each Fund, and concluded that such profits were reasonable and not excessive when compared to profitability guidelines set forth in relevant court cases. The Independent Trustees also reviewed reports comparing each Fund’s expense ratio and the advisory fees paid by each Fund to that of the applicable Universe and concluded that the advisory fee paid by each Fund and each Fund’s expense ratio was within the range of its respective Universe. The Independent Trustees noted that the Funds’ advisory fees were below the median for each Fund’s respective Universe. The Independent Trustees noted that the investment advisory fee for each Fund contained a number of breakpoints in an effort to reflect economies of scale that might be realized as each Fund grew. The Independent Trustees also noted that actual or potential economies of scale will be reasonably shared with the Fund shareholders through these breakpoints, fee waivers and expense reimbursement arrangements applicable to the Funds.

The Independent Trustees reviewed reports discussing the manner in which portfolio transactions for the Funds were conducted, including the use of soft dollars. Based on these reports, the Independent Trustees concluded that the research obtained by Parnassus Investments was beneficial to the Funds and that Parnassus Investments was executing each Fund’s portfolio transactions in a manner designed to obtain best execution for the Funds.

Based on their careful consideration of the information and factors described above, the Independent Trustees concluded that the approval of the continuation of the investment advisory agreements for the Trusts was in the best interest of the Funds and their shareholders. The Independent Trustees unanimously approved the continuation of the investment advisory agreements for an additional one-year period.
