Beginning on January 1, 2021, as permitted by regulations adopted by the U.S. Securities and Exchange Commission, paper copies of the Oakmark Funds' annual and semi-annual shareholder reports will no longer be sent by mail, unless you specifically request paper copies of the reports. Instead, the reports will be made available on Oakmark.com, and you will be notified by mail each time a report is posted and provided with a website link to access the report. If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. You may elect to receive shareholder reports and other communications from the Funds electronically anytime by contacting your financial intermediary (such as a broker-dealer or bank) or, if you hold your shares directly with the Funds, by calling 1-800-OAKMARK (625-6275) or visiting Oakmark.com.

You may elect to receive all future reports in paper free of charge. If you invest through a financial intermediary, you can contact your financial intermediary to request that you continue to receive paper copies of your shareholder reports. If you hold your shares directly with the Funds, you can call 1-800-OAKMARK (625-6275) to let the Funds know you wish to continue receiving paper copies of your shareholder reports. Your election to receive reports in paper will apply to all Funds you hold directly or all Funds you hold through your financial intermediary, as applicable.

FORWARD-LOOKING STATEMENT DISCLOSURE

One of our most important responsibilities as mutual fund managers is to communicate with shareholders in an open and direct manner. Some of our comments in our letters to shareholders are based on current management expectations and are considered "forward-looking statements." Actual future results, however, may prove to be different from our expectations. You can identify forward-looking statements by words such as "estimate", "may", "will", "expect", "believe",

"plan" and other similar terms. We cannot promise future returns. Our opinions are a reflection of our best judgment at the time this report is compiled, and we disclaim any obligation to update or alter forward-looking statements as a result of new information, future events, or otherwise.

Fund Expenses (Unaudited)

A shareholder of each Fund incurs ongoing costs, including investment advisory fees, transfer agent fees and other Fund expenses. The examples below are intended to help shareholders understand the ongoing costs (in dollars) of investing in each Fund and to compare these costs with the ongoing costs of investing in other funds.

The following table provides information about actual account values and actual Fund expenses as well as hypothetical account values and hypothetical fund expenses for shares of each Fund.

ACTUAL EXPENSES

The following table shows the expenses a shareholder would have paid on a $1,000 investment in each Fund from October 1, 2019 to March 31, 2020, as well as how much a $1,000 investment would be worth at the close of the period, assuming actual Fund returns and expenses. A shareholder can estimate expenses incurred for the period by dividing the account value at March 31, 2020, by $1,000 and multiplying the result by the number in the "Actual—Expenses Paid During Period" column shown below.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The following table provides information about hypothetical account values and hypothetical expenses for shares of each Fund based on actual expense ratios and an assumed rate of return of 5% per year before expenses, which are not the Funds' actual returns. The hypothetical account values and expenses may not be used to estimate the actual ending account balances or actual expenses shareholders paid for the period. Shareholders may use this information to compare the ongoing costs of investing in a Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as redemption fees. Therefore, the "Hypothetical—Expenses Paid During Period" column of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. If these transaction costs were included, the total costs would have been higher.

Portfolio Manager Commentary

oakwx@oakmark.com

At Oakmark, we are long-term investors. We attempt to identify growing businesses that are managed to benefit their shareholders. We will purchase stock in those businesses only when priced substantially below our estimate of intrinsic value. After purchase, we patiently wait for the gap between stock price and intrinsic value to close.

Halfway through the quarter, the stock market seemed poised to continue its strong 2019 performance, though at a somewhat muted rate of increase. The S&P 500¹ was up 3% and the Oakmark Fund hit a new all-time high NAV on February 12, even though growth stocks still dominated over value. We had little portfolio turnover as most of our holdings were selling at prices between our established buy and sell targets. Then, the bottom fell out. From February 20 through March 23, the S&P 500 declined 34%, the fastest drop of that magnitude in history.

The expected downturn in GDP, which many thought was overdue, will not occur because of excesses in the economy, but because of a voluntary shutdown to avoid a worst-case death toll from the coronavirus pandemic, COVID-19. A new vocabulary quickly emerged, including terms like "flatten the curve," "social distancing" and "shelter in place." Epidemiologists became TV stars, tourism stopped on a dime, schools were closed, workers were told to stay home, the oil market collapsed, corporate bond spreads exploded and investors grew more worried about the banking system than they had been since 2008. Our Funds performed poorly in both absolute and relative terms as the companies we thought were cheapest before the decline tended to be those that were viewed as benefitting the most from a continued strong economy.

We were unusually active in the second half of the quarter. We believe that extreme market volatility allowed us to increase the fundamental attractiveness of our portfolio. We were able to buy stocks in companies we believed offered greater undervaluation, higher quality or stronger balance sheets (and, in some cases, offered all three) than the companies we were selling. When markets make such extreme moves, desperate investors who need cash have to sell, and those with cash are able to buy—in contrast to normal conditions when trades tend to occur because investors have different time horizons or opinions on a stock's long-term value. In the past quarter, we often purchased from desperate sellers, using assets from our cash reserves or from selling off some of our holdings that had performed relatively well. To highlight the opportunities available: typically, we at Oakmark buy stocks priced at less than 60% of our estimate of business value and sell them when their price exceeds 90% of that value. During the past few weeks, we were selling stocks priced at 60% or more of our estimate of business value and buying companies priced at less than 40%. To us, these are incredibly compelling opportunities.

Amidst this turmoil, the financial media has been full of speculation as to whether or not the stock market bottom has been reached. We don't believe anyone knows and we know that we don't know either. Earlier this month, we wrote a note (https://oakmark.com/news-insights/responding-to-a-crisis/) reminding Oakmark shareholders that we don't consider mar-

ket timing to be a skill of ours, so instead we consistently encourage portfolio rebalancing. Today, that likely means selling assets that have performed well, like Treasury bonds, and using the proceeds to buy assets that have underperformed, like stocks. That restores the portfolio balance that existed prior to the stock market's downturn. In our personal accounts, most of the Oakmark portfolio managers bought more of the Oakmark Funds to rebalance our own investments.

As we look to the new quarter, we anticipate that our trading activity will remain at an elevated level as we continue to adjust to changing stock prices and capture the tax losses created by the downturn. We will also look even more closely at the management teams running our companies. We only invest in those companies that we believe are being managed to maximize long-term business value per share. We will evaluate what our companies accomplish during this downturn and revise our management quality ratings accordingly.

When we look back to 2008, some companies completed strategic acquisitions that were only possible because of the financial crisis: Wells Fargo purchased Wachovia, Liberty Media bought Sirius XM, Comcast bought NBC Universal and Berkshire Hathaway bought Burlington Northern. In hindsight, each of these added significantly to the acquirer's per share value. Other companies, such as Netflix, took advantage of their own depressed share price to reduce the number of shares outstanding, increasing each remaining share's percentage ownership. From late 2007 through 2010, Netflix repurchased 27% of its outstanding shares at an average price of $6 per share. Netflix today is priced at $372 per share, more than 60 times the repurchase price. We have no doubt that many of our companies will be looking for the value-enhancing opportunities created by this economic downturn.

On a final note, I want to express my thanks to the Harris Associates IT team. We've never been a work-from-home firm, believing that the corporate culture we so jealously guard would be eroded without the shared experience of being in the office together. Despite that, to protect our employees and our investors, we went to a work-from-home mandate a week before the city of Chicago did. It was no small task to make sure that all of our 200 employees could seamlessly communicate with each other, that our many data feeds were fully accessible and that we could execute the increased trading volume that we expected in a high volatility environment. It went off without a hitch.

Our analyst group has remained connected via daily group chats and weekly Zoom happy hours. With virtual meetings, we have maintained our tradition of sharing great lunchtime conversations as a team. It isn't perfect, so don't expect us to ever be one of those firms that works primarily from home. But given what I've heard from friends at other investment firms,

we've been able to maintain our usual routines better than most. And to all my colleagues at Harris Associates, if nothing else positive comes from this, working from home has made me extremely grateful for the wonderful bunch of people I typically get to see every day. I miss you all and look forward to the day we can be back in the office together.

We are hopeful that three months from now, when you read our second-quarter commentary, the Cubs will be playing baseball, we will be eating inside of restaurants and we will all be rescheduling the trips we've had to cancel. If that has happened, we believe the economy will likely recover quickly as will the stock market. But if it takes longer to return to normal, know that we have weighted our portfolios toward companies that we believe can survive a longer downturn and that we fully expect can emerge stronger on the other side.

Market volatility spiked during the first quarter of 2020 due to the considerable economic and social impact from the coronavirus. The Oakmark Fund declined 30% during the quarter, trailing the 20% decline for the S&P 500¹. Significant market volatility pushed share prices well below our estimates of intrinsic value and, therefore, we believe our portfolio is more attractively valued today than it was before the downturn. This has given us the opportunity to rebalance the portfolio toward companies with higher risk-adjusted returns, largely by trimming shares of our holdings that withstood the downturn relatively well. In one example of this value-enhancing rebalancing, we trimmed our position in Regeneron Pharmaceuticals, up 30% for the quarter, and added to our position in American International Group (AIG), which is down over 50%. With Regeneron moving up and AIG moving down, our estimate of AIG's long-term expected return is four times higher than Regeneron's.

As value investors, we always view heightened volatility as an opportunity to upgrade the portfolio, whether through rebalancing existing holdings, as with Regeneron and AIG, or by adding attractive new names to the portfolio when valuations become compelling. During the quarter, we added four new holdings to the portfolio (see below) and we eliminated our position in American Airlines because of uncertainty about its near-term cash flows and its likely need for restrictive government assistance. Sectors that detracted the least from our first-quarter returns were consumer staples and health care and our largest detractors were financials and consumer discretionary. Regeneron and Netflix were our best individual contributors for the quarter and the past six months, which seems fitting since both turned out to be well-positioned for a medical/quarantine crisis. Ally Financial and Citigroup were our worst contributors for the quarter, while Ally and Apache were our worst contributors for the past six months. Apache was impacted by declining oil prices, while Citigroup and Ally were impacted by falling interest rates.

Before we discuss our new holdings, I wanted to send a big thank you to the whole Harris Associates team! Unprecedented times have been met with an unprecedented effort and positive attitude by our amazing people. In this new work-from-home environment, our teams are working with focused diligence and communicating well internally and externally.

American Express Company (AXP-$90)

American Express has improved its cardholder value proposition in recent years by making significant investments in merchant acceptance, cardholder rewards and services, and small business payment tools. These efforts have accelerated both new card issuance and cardholder spending, and management has committed to reinvesting a portion of these incremental profits into further improvements in the company's value

proposition. We believe this virtuous cycle of growth and reinvestment will allow American Express to continue growing its business at a high single-digit pace in the coming years while investing enough to protect the business from competitive threats. The organic growth that we expect, combined with potential share repurchases, should result in double-digit EPS⁵ growth in a typical year, while the company's high returns and low credit risk should result in peer-leading results during the inevitable downturns. Management is making the right investments for the long term while also returning excess capital to shareholders. The shares are currently trading at just 11x last year's EPS, which we believe is too cheap for this caliber of business.

Match Group, Inc. (MTCH-$67)

Match Group operates a portfolio of the world's leading online dating brands. The company's flagship brand, Tinder, is the top dating platform in the world and holds a wide lead over its next largest competitors—several of which are also owned by Match. Because online dating is a network-effect business where each user makes the platform more valuable for others, we believe a market leader like Tinder has significant scale advantages. We believe this puts Tinder in an excellent position to address the more than 50% of singles in the U.S. and Europe who still haven't tried online dating. We also believe Tinder's monetization potential is underappreciated as its "freemium" model means the vast majority of users currently pay nothing for the service. With over 60% of its users active six days per week, the opportunity to increase adoption of paid features is substantial. Match is growing revenue in the high teens and the company has minimal capital requirements and operating margins that are already above 30%. We don't believe Match's current valuation reflects the company's combination of exceptional economics and long-term prospects.

Pinterest, Inc. Class A (PINS-$15)

Pinterest is an online discovery tool with a large and growing user base who visit the site to find ideas and inspiration for their personal tastes, interests and hobbies. We believe it is also an attractively valued investment opportunity as it has recently fallen to $14 per share from its high of $36 per share, which it hit last summer. Unlike many consumer internet companies, users and advertisers are fundamentally aligned on the site. Pinterest provides its users with information that they are actually looking for as opposed to trying to distract them from a newsfeed or chats with friends. The company also gives advertisers access to an audience of people with high commercial intent along with the ability to integrate ads in a natural way. Although Pinterest has more than 300 million active users from around the world each month, the company is in the early days of monetizing its platform. We believe that its shares are currently trading at a material discount to the company's intrinsic

value when benchmarking revenue and margin potential against its more mature internet competitors.

Workday, Inc. Class A (WDAY-$140)

Workday is the global leader in cloud-based software for human resources and finance departments at large enterprises. Around the world, businesses are embracing cloud computing to reduce costs and improve performance. When large companies transition their HR and finance applications to the cloud, they overwhelmingly choose Workday. Indeed, the company's HR software boasts over 70% market share of cloud deployments in the Fortune 500. As the global software market steadily transitions to cloud, we believe Workday will have a clear path to significant revenue growth. Despite the company's dominant competitive position and trajectory for sustained long-term growth, the stock trades at a lower multiple of revenue than other software companies that don't share Workday's competitive advantages. We view today's discount as an opportunity to invest in one of the world's most innovative companies at a reasonable price.

The Oakmark Select Fund was down 33% for the quarter, trailing the S&P 500 Index's¹ negative 20% return, in a quarter in which the Russell 1000 Value Index⁷ underperformed the Russell 1000 Growth Index⁸ by 13%. As Bill Nygren pointed out in his quarterly commentary (https://oakmark.com/news-insights/bill-nygren-market-commentary-1q20/), what started out as a relatively benign quarter turned terrible from late February onwards.

Our top contributor in the quarter and over the past six months was Regeneron Pharmaceuticals. The company is at the forefront of developing potential coronavirus treatments. The relative attractiveness of Regeneron stock has diminished substantially given its strong outperformance, but we still believe the company is selling at a discount to our estimate of its intrinsic value. Our largest detractor for the quarter was CBRE Group, which declined as the company's leasing and capital markets segments are directly exposed to the current cessation of economic activity. We still find CBRE an attractive investment. The company's outsourcing segment is less cyclical than other parts of its business and should be a durable source of cash flows during the downturn. CBRE has low net debt and significant liquidity. Rather than fighting for survival, its management team will likely be acting opportunistically to add per share value through this downturn. Our largest detractor for the past six months was Ally Financial as economic slowdown fears and falling interest rates pushed the company and our other financial stocks lower.

As you would expect during a period of rapidly changing prices and an evolving fundamental landscape, our trading has been much more active than usual. We took advantage of the extreme market volatility by adding four new positions: Booking Holdings, Constellation Brands, EOG Resources, and Facebook. We also initiated the sales of three others: American Airlines, Fiat Chrysler, and Concho Resources. We believe that by making these trades, we've increased the aggregate undervaluation at which the Fund trades relative to our estimate of value and improved the tax position of the Fund, all while upgrading the median balance sheet and business quality of the portfolio.

Booking Holdings is a global leader in the online travel industry. The company's share price has come under pressure due to concerns about the coronavirus' impact on global travel demand. While the company's near-term results will be significantly impacted by current travel restrictions implemented throughout the world, we believe the company's strong balance sheet and flexible cost structure will enable it to successfully navigate the steep decline in near-term demand and likely emerge even stronger once conditions improve. We expect demand for leisure travel to eventually fully recover, and on our forward earnings estimates in a more normal leisure travel mar-

ket, Booking trades at a meaningful discount to the S&P 500 Index, despite its superior growth outlook, strong competitive advantages, and high returns on incremental capital.

Constellation Brands is the largest imported beer company in the U.S. and one of the country's leading wine producers. Over the past five years, the company's beer segment, which includes brands, such as Corona, Modelo, and Pacifico, grew its revenue at an impressive 11% CAGR⁹ during a period in which industry volumes remained relatively flat. Constellation trades at a meaningful discount to other consumer packaged goods companies, which are experiencing slow to no growth. We are grateful for the opportunity to invest in an above-average business at a below-average price.

EOG Resources is the largest independent onshore oil producer in the U.S. Although there are many inexpensive companies in the energy space, few, in our view, can match EOG's combination of balance sheet strength, management ability, and diversified asset base. It is a conservatively run company with minimal leverage and efficient operations, which is highly likely to make it through this tough period unscathed. EOG is trading at a larger discount than peers to our estimate of the value of its current asset base, and it has a management team with a long history of creating shareholder value through opportunistic portfolio actions in times like these.

Facebook controls the world's most dominant social networking platforms, Facebook and Instagram. The company's unprecedented global reach and ad-targeting capabilities have made Facebook and Instagram some of the most sought after and effective advertising platforms ever created. Although the company will not be immune to the near-term disruption caused by the coronavirus, we believe the long-term outlook for its digital advertising remains as bright as ever. Facebook is trading at a discount to the S&P 500 Index on our two-year forward estimates, even though those estimates include no contribution from valuable assets, like WhatsApp and Messenger (among others), which Facebook has yet to monetize. We believe this is an attractive valuation for a company that is projected to grow its revenue in the double digits for the foreseeable future, and we believe that Facebook's operating margin potential is substantially higher than what the company is likely to report in the coming years.

Thank you, our fellow shareholders, for your continued investment in our Fund.

The Pandemic Market

Fastest decline into a bear market ever. Shortest time spent in a bear market ever. Eight consecutive days when the market either rose or fell by over 4%. Largest one-day stock market gain since 1933. Second-largest one-day drop ever. A collapse in the price of oil. Remarkable individual stock volatility. Growth outperforms value by a near-record amount. Small- and mid-cap issues suffer major price declines, far in excess of large caps. The U.S. registers the largest number of weekly unemployment claims ever by a factor of more than three times. The Federal Reserve reduces the Fed funds rate to 0%. Congress passes an economic stimulus package of more than $2 trillion. We are truly living and investing in what we believe is an extraordinary time.

History teaches us that it takes time for the market to stabilize and regain its footing after such an amazing disruption. We believe that our proper course of action in such a time is to attempt to seize moments of extreme price dislocation and to improve the Fund's tax position for our taxable clients. To that end, we have been fairly active. Market turmoil has affected the Fund's asset allocation, and we are working to realign the portfolio appropriately. Our most important advice to clients during this tumultuous time is to take the same action we are—rebalance. If two months ago your asset allocation was appropriate for your circumstances, you probably need to act to return to that allocation.

The Oakmark Equity and Income Fund declined 22% in the quarter, which contrasts to a 13% loss for the Lipper Balanced Fund Index¹⁰, the Fund's performance benchmark. Value stocks' severe underperformance during the downturn was the main reason for this shortfall. For the fiscal six months, the Fund showed a loss of 17%, compared to 8% for the Lipper Index. The quarter's decline has dented the Fund's return since inception, but we are still pleased to report that it is 8.7%, while the corresponding return for the Lipper Index is 6.3%.

The only contributors to portfolio return in the quarter were Regeneron Pharmaceuticals, Oracle (sold) and Zimmer Biomet, a new purchase discussed below. Bank of America, General Motors, TE Connectivity, Citigroup and Ally Financial detracted most. For the first six months of the Fund's fiscal year, Regeneron, Charter Communications, UnitedHealth Group, Zimmer Biomet and Oracle were contributors, while General Motors, TE Connectivity, Ally Financial, Bank of America and Citigroup detracted most from return. The pandemic has caused investors to flee financial company stocks even though these companies have far stronger balance sheets than they had during the 2008 downturn. Combined with the extraordinary support that

governments worldwide are throwing at the economy, these balance sheets should enable our financial holdings to fare well in this crisis.

Fixed Income Sector Review

In fixed income, the dizzying pace of developments stemming from the virus was remarkable. Corporate bond yields had been at an all-time low, underpinned by record unemployment and a benign growth outlook, but coronavirus concerns caused them to catapult to levels that implied a substantial U.S. corporate default cycle—greater than 20% by our estimation—and an imminent recession. Meanwhile, the Fed pivoted from voting on the merits of a 1.75% policy rate to dropping that same rate to 0% and announcing the largest monetary stimulus (~$4 trillion-$5 trillion) on record. Liquidity programs, like the Commercial Paper Funding Facility (CPFF), an artifact of the financial crisis, were dusted off and deployed alongside entirely new programs, such as the Primary Market Corporate Credit Facility (PMCCF). This was all in a matter of weeks. Despite the frenzy of market activity, we kept the Fund's fixed income exposures relatively stable during the quarter. Coming into the period, our views that corporate credit valuations were priced close to perfection had the Fund aligned in shorter duration, non-cyclical corporates, which protected us well during the historical jump in credit spreads. In addition, the portfolio's short-duration Treasury positioning helped dampen the overall portfolio volatility, but we missed out on the significant returns generated by longer dated government bonds during the period.

As we move forward, we see a compelling opportunity to trim our highest quality corporates, which have been relatively unscathed by the pandemic, and invest in securities whose issuers' business values we believe will largely remain intact as we emerge from this crisis. This doesn't go without a major caveat, however. Given the sudden stop to the economy, we are now hyper focused on companies' liquidity runways over the next 12 months to ensure that they will be solvent enough to realize their longer term valuations. As for Treasurys, the Fund missed out on some return over the past several years by adhering to a short duration, but nevertheless, we remain convinced that maintaining a short duration is the correct policy. We view the asymmetrical downside returns longer out on the curve as quite possibly the most skewed risk-versus-reward profile investors are facing across any major asset class in the market today. Yes, all-time low rates could persist for some time as we deal with the economic fallout from the coronavirus. On the other hand, the unprecedented global stimulus efforts, combined with a peak in coronavirus case rates, could prompt a long overdue return to fundamentals. If, as a result, there is a

Portfolio Manager Commentary (continued)

stampede out of Treasurys that approaches the intensity of the stampede into them, rates will likely appreciate rapidly and long-duration investors could incur meaningful mark-to-market losses. In contrast to historical precedent, investors are now collecting close to zero in yield as they await which scenario will play out.

Equity Transaction Activity

The recent quarter's extreme volatility afforded us many opportunities to try to upgrade the equity portfolio and increase tax efficiency. In other words, trading was active. We initiated three new equity holdings and eliminated five. Our first new purchase was actually a return to a previous holding, Reinsurance Group of America (RGA). RGA is primarily in the business of reinsuring life insurance contracts. When the coronavirus began to be understood as a worldwide pandemic, RGA's share price collapsed to levels that, in our view, reflected a worst case scenario. Our discussions with management buttressed that assessment and we established a position at a price well below the company's book value. For an insurance company, RGA maintains an unusually conservative balance sheet and an investment portfolio with relatively few equities. We also like the company's management team, most of whom were in place when we last owned the stock three years ago.

Our second new purchase was Thor, a manufacturer of towable trailers and motorized recreational vehicles. The company controls the largest market share in this industry, followed by Warren Buffett's Berkshire Hathaway-owned Forest River in the second position and Winnebago at a distant third. Although some recreational industry products have struggled to penetrate the millennial and Generation-X markets, RVs have proven to be an exception. In fact, recent surveys show that the average age of RV owners is getting younger. In addition, the higher proportion of sport utility vehicles on the road today also benefits Thor, since most of these vehicles come outfitted with towing capability. Finally, camping continues to increase in popularity and RVs are the choice for many campers. We have followed the company for many years and respect its management team considerably. Impressively, Thor has never experienced a loss year, despite the cyclical nature of its business. We purchased the stock during the quarter at a low multiple of our estimate of trend earnings.

The third new purchase was Zimmer Biomet Holdings, the worldwide leader in orthopedic implements. The rationale for this purchase is unusually simple and coronavirus derived. As the world focuses on treating individuals infected with the virus, hospitals have postponed or canceled elective procedures, such as knee replacements. This development caused Zimmer stock to drop precipitously to levels that we find quite attractive. In normal times, joint replacement surgery is one of the most frequent Medicare procedures, and the aging Baby Boom generation makes it likely that these procedures will only become more common. (The author of this section of the report has had both knees replaced and can recommend the procedure.) We believe that most of these postponed procedures will eventually take place, though this is obviously dependent on the health care system first controlling the coronavirus. We like

Zimmer's management team and expect the company's reenergized new product development to be fruitful.

We eliminated our holdings in American Airlines, Diamondback Energy, EOG Resources, Oracle and WESCO International. All but Oracle produced tax losses that were used to offset previously taken capital gains. The pandemic has crushed demand for travel and American Airlines shares have suffered greatly. The oil price war between Saudi Arabia and Russia began just as the pandemic was developing, and the combination of economic slowdown and price war has impaired the prospects of U.S. energy companies, including Diamondback and EOG. Lastly, WESCO management may have committed to the most unfortunate transaction in the current economic and health crisis. The company engaged in an acquisition battle for Anixter, an electronics distributor, becoming the dubious winner of this battle in mid-January. This is a large deal for WESCO, requiring the issuance of shares and significant debt. As market turbulence increased in March, investors fled highly leveraged companies, including WESCO. Finally, we sold Oracle to accommodate purchases of more attractive issues.

Hello/Goodbye

With this report we welcome Adam Abbas, leader of our firm's fixed income team, as a co-manager of the Equity and Income Fund. Adam replaces Edward Wojciechowski, who has ably served as Fund co-manager for the past seven years. When Edward joined the team, he was Harris Associates' director of fixed income. Since then, he has moved on to different responsibilities. Although Edward has stepped down as a co-manager, we will continue to draw upon his investing acumen. Adam has served as a fixed income portfolio manager and analyst at several other firms. He joined Harris in 2019. Adam penned the "Fixed Income" section of this report. We look forward to his contributions to the Fund's success.

As always, we thank our fellow shareholders for investing in the Equity and Income Fund.

Quarter Review

It was a terrible quarter for the world, the markets and the Oakmark Global Fund. We will not repeat here all that you have been reading about the spread of the coronavirus and the efforts to "flatten the curve." Government action, both in terms of public health and economics, has been unprecedented around the globe. Hundreds of economic stimulus efforts have been put into effect, including a $2 trillion plan in the U.S., but despite all of these efforts, economic revival depends more on the outcomes in the public health and medical community. Stock market volatility has breached many historic records. Several emerging market countries are predicted to default on their outstanding debt soon. Investors have sought liquidity wherever they can find it, shunning anything with financial leverage, including banks. Smaller capitalization issues have been hit particularly hard.

We have no ability to predict the pandemic's end, but we firmly believe that this, too, will pass and that the turbulent market it is creating—and will continue to create—will generate compelling opportunities for long-term investors. John Authers of Bloomberg recently advised his readers, "Buy when there are germs in the street," a reworking of Lord Rothschild's "Buy when there is blood in the street."¹⁴ We are not contrarians like Lord Rothschild, but we believe that the values present today are likely to prove to be the foundation for strong future returns. At the mid-March market lows, the issues held in the Fund were trading at valuations close to the levels reached at the depths of the 2008-2009 financial crisis, yet we believe these companies' financial conditions are considerably superior to what they were at that time. We recommend that our shareholders revisit their asset allocation to determine if it still fits their personal circumstances. With equities declining so much, many investors are now underweight their desired allocation. The Fund's portfolio managers have done this review ourselves and most have added to our Fund holdings.

The Fund lost 35% in the quarter, which compares to the MSCI World Index's¹² 21% loss in the period and the Lipper Global Fund Index's¹³ loss of 22%. As an all-capitalization, value-oriented portfolio, the Fund was poorly positioned for a bear market in which growth and large caps outperformed. For the first six months of the Fund's fiscal year, the returns are –28% for the Fund, –14% for the MSCI World Index and –16% for the Lipper Global Fund Index. Since inception in 1999, the Fund has achieved a compound annual rate of return of 7.6%, which compares to 3.9% for the MSCI World Index and 4.3% for the Lipper Global Fund Index.

For the quarter, every country represented in the Fund detracted from return. The U.S., U.K. and Germany detracted most, basically reflecting that they are the three most highly represented countries in the portfolio. New purchases Prudential (U.K.) and Prosus (Netherlands—position now eliminated) were the only positive contributors to the Fund's return. The Fund holdings that detracted most were Lloyds Banking Group (U.K.), CNH Industrial (U.K), Daimler (Germany), Bank of America (U.S.) and General Motors (U.S.).

For the first six months of the Fund's fiscal year, Taiwan and the Netherlands contributed to investment return, while the U.S., U.K. and Germany detracted most. Leading contributors to return were Prudential, Taiwan Semiconductor (Taiwan), Liberty Broadband (U.S.) and Charter Communications (U.S.). CNH Industrial, General Motors, Lloyds Banking Group, TE Connectivity (U.S.) and Daimler detracted most from return.

Portfolio Activity

In 2019, the Fund's U.S. holdings enjoyed a particularly strong year, in our opinion. In early 2020, we determined that it was time to "freshen" the portfolio and, to that end, we began cutting back appreciated holdings and introducing new names. Given what has transpired, we would have been better off if we had moved entirely to cash, of course, but we believe that our efforts to update and better diversify the portfolio can eventually pay off.

We initiated three new U.S. holdings in the quarter and one international holding. One of these purchases was the result of our decision to revamp the Fund's energy exposure to reduce its oil service component and introduce exposure to high-quality exploration and production. As a result, we purchased EOG Resources, which we believe is one of the best positioned U.S. energy companies. The key to EOG's story is the company's management team. It has focused intensely on capital productivity and, as a result, has made EOG a true low-cost producer. It has also allocated the company's capital effectively, giving EOG a strong balance sheet. This should enable the company to survive—and even benefit from—the currently stressed oil and gas environment. Even including the EOG purchase, however, it is worth noting that the energy sector remains a mere 1% weight in the portfolio.

Our second new U.S. purchase is a relatively new company, Envista Holdings, a 2019 spinoff from Danaher. Danaher spent 16 years acquiring 25 different dental product manufacturers and combining them into one decentralized entity. The opportunity with Envista now as an independent concern is to

Portfolio Manager Commentary (continued)

eliminate redundant cost structures and expand margins. Envista's products span much of what is seen in any dental office, though the company realizes its highest profit margins on its specialty lines sold to oral surgeons, endodontists and orthodontists. We first became interested in the company several months ago, but the market decline drove the stock price down to what, in our view, was an undervaluation. Even though all but the most critical dental procedures have been postponed into an uncertain future, it seems unlikely that the current crisis will permanently change the dentist/patient experience. One outcome of this pandemic could be that many medical visits change permanently to remote, but teeth cleaning or root canals do not lend themselves to that outcome.

The last U.S. new purchase is Pinterest, a 2019 new issue. Pinterest is a website that provides users with a rich, visually appealing platform where they can become more inspired and informed about their personal interests (e.g., cooking, fly fishing, home design, crafting). As our analyst for the stock wrote, "Pinterest combines some of the useful features of internet search with some of the enjoyable features of media while enabling users to get things done." Users actively seek relevant commercial content, meaning that they are fundamentally aligned with advertisers on the site, a factor not evident on many other media platforms. Advertisers highly value Pinterest users' consumer intent. They also value the ability to reach U.S. millennials, more than half of whom visit the platform each month. The current pandemic has less effect on Pinterest than on many other companies, and it may even benefit from lockdowns as people devote more time to their hobbies. Finally, we believe Pinterest is trading quite cheaply compared to its internet peers and find the management team impressive.

In international holdings, we added Prudential PLC, a global life and health insurance provider, to the Fund during the quarter. Although Prudential is headquartered in the U.K., we estimate that over 90% of its value is derived from Asia, where it possesses strong franchises in Hong Kong, Indonesia and China. Over the past decade, Prudential's Asian franchise has produced impressive double-digit growth in profit and value creation while generating a return on equity¹⁵ of more than 20%. This strong performance has been driven by two structural tailwinds that we expect to continue for many years to come. First, Asian consumers' increased wealth has significantly driven demand for insurance and financial planning products. Secondly, a massive demographic transition has created an aging population increasingly in need of retirement-related products and services. Yet, the penetration of life and health insurance in Asia remains relatively low compared to other markets. In addition to the structural benefits of the Asian market, we believe Prudential enjoys strong brand recognition, significant scale and financial stability, giving it an attractive competitive position. Finally, its adept management team spun-off the company's European operations in 2019 and is preparing to do the same for U.S. operations, which will then enable the company to focus exclusively on the strong Asian market. Although the quarantine has made it difficult for Prudential's agents to sell new products, the outbreak has not materially affected insurance-related payouts. We also believe that any setbacks Prudential experiences will likely be temporary and that the pandemic will actually increase awareness about the importance of both health and life insurance products. Yet, the broader market downturn has enabled us to purchase Pruden-

tial at a highly discounted valuation on both an absolute and relative basis.

We eliminated two holdings from the portfolio in the quarter, Prosus and Under Armour. Prosus was spun out of Naspers in the parent company's effort to reduce the discount in its valuation. When Prosus shares outperformed other Fund holdings, including Naspers, we sold the position, especially since Naspers continues to own the same underlying asset pool and itself trades cheaper. We sold Under Armour to harvest a tax loss and to reposition funds into more attractive issues. This activity, combined with the volatile market, reduced the U.S. portfolio weight from 46% to 44%.

Currency Hedges

We defensively hedge a portion of the Fund's exposure to currencies that we believe to be overvalued versus the U.S. dollar. As of quarter end, we found the Swiss franc to be overvalued and have hedged approximately 11% of the Fund's franc exposure.

As David Herro wrote in his lead letter (https://oakmark.com/news-insights/david-herro-market-commentary-1q20/), it was a difficult quarter for global markets and the Oakmark Global Select Fund was not exempt. The Fund declined 30.7% for the quarter ended March 31, compared to the MSCI World Index¹², which lost 21.1%. Since the Fund's inception in October 2006, it has returned an average of 4.8% per year. The top contributor for both the quarter and the past six months was Regeneron Pharmaceuticals (U.S.), while the largest detractor for the same time periods was CNH Industrial (U.K.).

While we are disappointed in our performance results, we believe our Fund is well positioned and continues to offer value for our long-term shareholders. Although our holdings' share prices have fallen 30-50%, we consider the impact on their underlying business values to be much less. We believe current market conditions provide opportunities to buy high-quality companies at low prices, the cornerstone of value investing.

As market prices have fluctuated much more than our estimate of intrinsic value, our trading activity has picked up as we reposition the portfolio for the long term. The market volatility provided an opportunity to add two new holdings to the Fund this quarter: Booking Holdings (U.S.) and NAVER (South Korea).

Booking Holdings is a provider of online travel services, including airline tickets, hotels, rental cars, cruises and vacation packages along with restaurant reservations. The company conducts its operations via several brands, including Priceline.com, Booking.com, KAYAK and OpenTable, among others. In our view, Booking is a high-quality company that maintains a healthy market share, strong brands and scale advantages in the online travel agency industry. Booking benefits from an increasingly powerful network effect, an overall transition to booking travel online and a generational spending shift that appears to favor "experiences" over "material possessions." The company enjoys broad geographic reach and, unlike its peers, it derives a large majority of its profits from Europe, where it focuses on lodging. Contrary to the U.S., European lodging supply is mostly owned and operated by independent hoteliers who rely on Booking to match excess inventory with demand. Only about 40% of global travel and leisure tourism arrangements are now conducted online, with a historical growth rate of one to two percentage points per year. We think this provides Booking with ample potential to increase its market share of total global accommodations (which is currently estimated to be 10%). During the quarter, Booking's share price fell in conjunction with several other travel-related companies due to concerns

about the spreading coronavirus. We initiated a position during the quarter as the decline in valuation led to an attractive risk-reward proposition.

NAVER holds the dominant market share in South Korea's search engine space for both PCs and mobile. In our view, the company's dominance stems from its high-quality search results as NAVER is better equipped than Google to process Korean syntax, so it tends to produce more relevant results for its users. In addition, Koreans' preference for a portal experience (as opposed to a strictly search engine-based website) and the incorporation of other services/assets make the company even more attractive, in our view. We also believe NAVER should benefit significantly from further e-commerce growth in Korea, most notably from additional advertising revenue, as inventory and pricing increase with display and video ads. Furthermore, the company holds a significant ownership stake in LINE, the most popular messaging app in Japan, Thailand and Taiwan. We initiated a position during the quarter as the decline in valuation led to an attractive risk-reward profile.

During the quarter, we exited two positions: Fiat Chrysler (U.K.) and Taiwan Semiconductor (Taiwan).

Geographically, we ended the quarter with approximately 50% of our holdings in the U.S., 45% in Europe and the U.K., and 5% in Asia.

We continue to believe the Swiss franc is overvalued versus the U.S. dollar and we defensively hedged 10% of the Fund's franc exposure.

We are reminded that these difficult economic times can create compelling buying opportunities. Our long-term focus allows us to attempt to take advantage of these short-term price dislocations. We believe the portfolio consists of high-quality companies that can provide our shareholders with attractive returns in the years to come. We thank you for your continued confidence.

Small Cap Funds March 31, 2020

Portfolio Manager Commentary

David G. Herro, CFA

Portfolio Manager

oakgx@oakmark.com

Fellow Shareholders,

In the wake of the impact of the coronavirus pandemic, I am disappointed to write that the Oakmark International Fund and Oakmark International Small Cap Fund have had extremely weak performance numbers in the first calendar quarter of 2020. Please see individual Fund letters for performance data. Despite this extreme downdraft in share prices, our team remains convinced that our Funds continue to offer value for long-term investors.

The Shock vs. Fundamentals

The resulting shock to share prices from the uncertainty surrounding the above-mentioned pandemic has meant that many of the businesses in which we are invested have had share price declines in the 30-50% range. The role of our team is to determine what, in fact, given the best and most current information available, has happened to our measurement of intrinsic value.

It is our belief, based on simple economics and financial theory, that what makes a company valuable are the cash flow streams it is able to generate in the present and future. Whereas "Mr. Market" often merely considers the short term in pricing businesses, we believe this does not at all reflect the true intrinsic value of a business. And given how fluid this current crisis is, I would speculate that "Mr. Market" has become even more short term.

Even when we account for an extremely severe short-term global economic contraction followed by a muted recovery, our measurement of intrinsic value for most of our shareholdings drops by an amount that ranges from mid-single digit to low-double digit levels (please also see Win Murray's post (https://oakmark.com/news-insights/potential-impact-of-coronavirus-on-long-term-holdings/) regarding this topic). Given this wide spread between how the market has priced these businesses and what we believe to be their intrinsic value as determined by cash flow streams, we believe today's situation can be a great opportunity for value investors.

Our Actions

Since the beginning of this volatile market situation, we have been busy focusing on three things: remaining up to date on business values, keeping the portfolio "forward" positioned and seeking new investment opportunities.

Taking the first point, as we generally base position size in portfolios on the spread between market price and our measurement of value, it is critical that we stay current as to what we believe our businesses are valued. To this end, we have spent considerable time speaking to managements and other industry

sources in keeping our estimates current. The fact that we have been working from home since mid-March has not been a deterrent. And it's important to note that in almost all cases, our companies' managements have proactively made themselves available to communicate with their shareholders.

Regarding the second point, with the extreme volatility in the market prices of businesses, our more moderate changes in our measurement of value have catalyzed increased portfolio trading and positioning. This is generally the case in volatile markets, but given the extreme price movements, even intraday, we have been quite busy keeping the portfolio position sizes consistent with potential upsides.

Lastly, given aggressive price movement everywhere, new idea research activities have picked up measurably, which provide new investment opportunities.

Value Investing—Revisited

This downturn has not only severely impacted our portfolios, but has caused the gap between "value stocks" and "non-value stocks" to expand significantly. We remain confident and steadfast that this divergence can create better future performance (please see our piece "The Value of Value" (https://harrisassoc.com/news-insights/the-value-of-value/)). Today, our portfolios trade at near all-time discounts to their historical averages, trading at around 40 cents on the dollar. For example, blue chip holdings, like BNP Paribas and Credit Suisse Group, trade for at or around 40% of tangible book value, which is below the valuation level during the last financial crisis, despite materially stronger balance sheets, in our opinion. Another example is BMW, the global leader in premium autos, which has an enterprise value under €20 billion, despite having excess cash on its balance sheet and what we estimate normalized sales, less their finance business of close to €100 billion, with operating profits of more than €7 billion by 2022.

This unique and unprecedented environment certainly isn't pleasant, but we believe it has the potential to provide us with an opportunity for long-term value creation. Your patience and support are greatly appreciated during this extraordinary time.

As David Herro wrote in his lead letter (https://oakmark.com/news-insights/david-herro-market-commentary-1q20/), it was a difficult quarter for global markets and the Oakmark International Fund was not exempt. The Fund declined 38.1% for the quarter ended March 31, compared to the MSCI World ex U.S. Index¹⁶, which lost 23.3%. Since the Fund's inception in September 1992, it has returned an average of 7.4% per year. The top contributor for the quarter was Olympus (Japan), while the largest detractor was Glencore (Switzerland). Over the course of the past six months, the top contributor was Ferguson (U.K.), while the largest detractor was Glencore.

While we are disappointed in our performance results, we believe our Fund is well positioned and continues to offer value for our long-term shareholders. Although our holdings' share prices have fallen 30-50%, we consider the impact on their underlying business values to be much less. We think current market conditions have created opportunities to buy high-quality companies at low prices, the cornerstone of value investing.

As market prices have fluctuated much more than our estimates of intrinsic value, our trading activity has picked up as we reposition the portfolio for the long term. The market volatility provided an opportunity to add two new holdings to the Fund this quarter: Prudential (U.K.) and Alibaba Group (China).

Although Prudential, a global life and health insurance provider, is headquartered in the U.K., we estimate that over 90% of its value is derived from Asia, where it possesses strong franchises in Hong Kong, Indonesia and China. We believe that two structural factors will continue to boost the Asian market for years to come. First, Asian consumers' increased wealth has significantly driven demand for insurance and financial planning products. Secondly, a massive demographic transition has created an aging population increasingly in need of retirement-related products and services. Yet, the penetration of life and health insurance in Asia remains relatively low compared to other markets. In addition to the structural benefits of the Asian market, we believe Prudential enjoys strong brand recognition, significant scale and financial stability, giving it an attractive competitive position. While the quarantine has made it difficult for the company's agents to sell new products, the outbreak has not materially affected insurance-related payouts. We also believe that any setbacks Prudential experiences will likely be temporary and that the pandemic will actually increase awareness about the importance of both health and life insurance products and, therefore, serve to increase penetration rates over time.

Alibaba is one of the largest internet platforms in China and a market leader in several businesses, including e-commerce, cloud and fintech via the company's partial ownership in Ant

Financial. The management team has proven itself to be quite astute and has positioned the company at the forefront of several technological trends in China. We believe Alibaba will continue to enjoy rapid long-term growth, especially since several of its businesses remain underpenetrated and have yet to fully scale. We initiated a position during the quarter as the decline in valuation led to an attractive risk-reward profile.

During the quarter, we exited six positions: ASML Holding, Meggitt, Olympus, Prosus, OMRON and Willis Towers Watson.

Geographically, we ended the quarter with approximately 82% of our holdings in Europe and the U.K., 10% in Asia, and 3% in Australasia. The remaining positions are 2% in Africa (South Africa), 2% in North America (Canada) and 1% in Latin America (Mexico)

We continue to believe the Swiss franc is overvalued versus the U.S. dollar and we defensively hedged 11% of the Fund's franc exposure.

As David Herro wrote in his lead letter (https://oakmark.com/news-insights/david-herro-market-commentary-1q20/), it was a difficult quarter for global markets and the Oakmark International Small Cap Fund was not exempt. The Fund declined 38.3% for the quarter ended March 31, compared to the MSCI World ex U.S. Small Cap Index¹⁹, which lost 28.4%. Since the Fund's inception in November 1995, it has returned an average of 6.8% per year. The top contributor for the quarter was Sugi Holdings (Japan), while the largest detractor was Konecranes (Finland). Over the course of the past six months, the top contributor was ConvaTec Group (U.K.), while the largest detractor was Konecranes.

While we are disappointed with the Fund's short-term performance, we remain optimistic about its mid- to long-term positioning. Although our holdings' share prices have fallen 30-50%, we believe the impact to their underlying business values has been much less. When looking at the discount to our estimate of intrinsic value, we believe this is the most attractive our portfolio has been since the depths of the financial crisis. Even though the coming months will likely remain volatile, we believe today's low share prices could generate attractive rates of return over the mid to long term.

We have been busy using the elevated levels of volatility to reposition the portfolio toward our most compelling investment opportunities. During the quarter, we added to many of our holdings that had experienced share price declines far in excess of the declines in our estimates of their business values. Some of our most significant additions were to Autoliv (Sweden) and Autogrill (Italy). Autoliv is a supplier of passive safety equipment to the auto industry. The company's share price declined over 40% in the quarter. Although auto production shutdowns will cause short-term disruptions at the company, its strong balance sheet and new platform launches should help Autoliv grow revenue well in excess of the growth in light vehicle production in the coming years. Autogrill is a global leader in food-and-beverage retail to the travel sector. Its primary business is operating food retail concessions at airports globally. In the short term, the business will face considerable challenges due to coronavirus-related travel restrictions. However, we believe the recent 60% decline in the company's share price already accounts for the potential impacts of these near-term disruptions along with mid-term declines in passenger volumes. We cannot predict how long the pandemic will last and we anticipate that the company could experience severe short-term shocks. However, we expect that both leisure and business travelers will eventually return to airports, which will benefit Autogrill's business.

We also used the market volatility to add three new holdings to the Fund this quarter: Wynn Macau (China), dormakaba Holding AG (Switzerland) and Software AG (Germany). Wynn Macau, which is majority-owned by parent company Wynn

Resorts, owns and operates two luxury hotel and casino resorts in the Macau region of China. We believe Wynn owns some of the most luxurious properties in Macau and is among one of the segment's most efficient operators. The company's share price fell following the temporary closure of Macau's casinos during the coronavirus outbreak, and we used this opportunity to establish a position. Dormakaba is a Swiss-based provider of mechanical and electronic security systems and a long-term holding of the Fund. We exited the position late last year as the share price approached our view of intrinsic value. The recent market downturn gave us the opportunity to reestablish a position in this high-quality and relatively defensive industrial business. German-based Software AG is the largest independent integration software provider, operating in more than 70 countries. The company provides tools that allow applications to communicate and work together even if they are made by different vendors, hail from different generations or use vastly different information architectures. We believe Software AG's underlying business quality is high, yet the company trades at a significant discount to its software peers.

During the quarter, we exited three positions—Criteo (France), Ontex Group (Belgium) and Wajax (Canada)—as we reallocated capital to investments with more favorable risk-return profiles.

Geographically, we ended the quarter with approximately 70% of our holdings in Europe and the U.K., 13% in Asia, and 7% in Australasia. The remaining positions are 5% in Latin America (Mexico) and 5% in North America (Canada).

We continue to believe the Swiss franc is overvalued versus the U.S. dollar and defensively hedged 10% of the Fund's franc exposure.

During these turbulent times, we thank you for your ongoing patience and support. We will remain steadfast in our pursuit of finding attractive, undervalued companies with management teams dedicated to building shareholder value to add to the Fund.

1. SIGNIFICANT ACCOUNTING POLICIES

Organization

The following are the significant accounting policies of Oakmark Fund ("Oakmark"), Oakmark Select Fund ("Select"), Oakmark Equity and Income Fund ("Equity and Income"), Oakmark Global Fund ("Global"), Oakmark Global Select Fund ("Global Select"), Oakmark International Fund ("International"), and Oakmark International Small Cap Fund ("Int'l Small Cap"), collectively referred to as the "Funds," each a series of Harris Associates Investment Trust (the "Trust"), a Massachusetts business trust, organized on February 1, 1991, which is registered as an open-end management investment company under the Investment Company Act of 1940, as amended (the "1940 Act") and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 946 Financial Services—Investment Companies. Each Fund, other than Select and Global Select, is diversified in accordance with the 1940 Act. The following policies are in conformity with accounting principles generally accepted in the United States of America ("GAAP"). The presentation 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 amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and assumptions.

Class disclosure

Each Fund offers four classes of shares: Investor Class Shares, Advisor Class Shares, Institutional Class Shares and Service Class Shares. Investor Class, Advisor Class and Institutional Class Shares are offered for purchase directly from the Funds and through certain intermediaries who have entered into an agreement with the Funds' distributor and/or Harris Associates L.P., investment adviser to the Funds (the "Adviser"). Service Class Shares are offered to certain retirement plans, such as 401(k) and profit sharing plans. Service Class Shares pay a service fee at the annual rate of up to 0.25% of the average net assets of Service Class Shares of the Funds. This service fee is paid to intermediaries for performing the services associated with the administration of such retirement plans. Global Select had no outstanding Service Class Shares during the six-month period ended March 31, 2020.

Income, realized and unrealized capital gains and losses, and expenses of the Funds not directly attributable to a specific class of shares are allocated to each class pro rata based on the relative net assets of each class. Transfer and divided disbursing agent fees, other shareholder servicing fees, and reports to shareholders expenses are specific to each class.

Security valuation

The share price is also called the net asset value (the "NAV") of a share. The NAV of shares of each class is normally determined by the Funds' custodian as of the close of regular session trading (usually 4:00 p.m. Eastern time) on the New York Stock Exchange (the "NYSE") on any day on which the NYSE is open for regular trading. If the NYSE is unexpectedly closed on a day it would normally be open for business, or if the NYSE has an unscheduled early closure, the Funds reserve the right to accept purchase and redemption orders and calculate their share price as of the normally scheduled close of regular trading on the NYSE for that day.

The NYSE is closed on Saturdays and Sundays and on New Year's Day, the third Mondays in January and February, Good Friday, the last Monday in May, Independence Day, Labor Day, Thanksgiving and Christmas. If one of these holidays falls on a Saturday or Sunday, the NYSE will be closed on the preceding Friday or the following Monday, respectively. A Fund's NAV will not be calculated on days when the NYSE is closed. The NAV of a class of Fund shares is determined by dividing the value of the assets attributable to that class, less liabilities attributable to that class, by the number of outstanding shares of that class.

Trading in securities of non-U.S. issuers takes place in various markets on some days and at times when the NYSE is not open for trading. In addition, securities of non-U.S. issuers may not trade on some days when the NYSE is open for trading. The value of the Funds' portfolio holdings may change on days when the NYSE is not open for trading and you cannot purchase or redeem Fund shares.

Equity securities principally traded on securities exchanges in the United States are valued at the last sale price or the official closing price as of the time of valuation on that exchange, or lacking a reported sale price on the principal exchange at the time of valuation, at the most recent bid quotation. Each over-the-counter security traded on the NASDAQ National Market System shall be valued at the NASDAQ Official Closing Price ("NOCP"), or lacking a NOCP at the time of valuation, at the most recent bid quotation. Other over-the-counter securities are valued at the last sales prices at the time of valuation or, lacking any reported sales on that day, at the most recent bid quotations. Each equity security principally traded on a securities exchange outside the United States shall be valued, depending on local convention or regulation, at the last sale price, the last bid or asked price, the mean between the last bid and asked prices, the official closing price, an auction price, or the pricing convention accepted as the official closing price by MSCI for their index calculations. If there are unexpected disruptions in the primary market or valuations from the primary market are deemed suspect, equity securities may be valued based on a pricing composite or valuations from another exchange as of the close of the regular trading hours on the appropriate exchange or other designated time. The market value of exchange-traded securities is determined by using prices provided by one or more independent pricing services, or, as needed, by obtaining market quotations from independent broker-dealers. Short-term debt instruments (i.e., debt instruments whose maturities or expiration dates at the time of acquisition are one year or less) or money market instruments are valued at the latest bid quotation or an evaluated price from an independent pricing service. If a bid quotation or evaluated price from a pricing vendor is not available for short-term debt instrument or money market instrument maturing in 60 days or less from date of valuation, such instruments are valued at amortized cost, which approximates market value. All other debt instruments are valued at the latest bid quotation or at an evaluated price provided by an independent pricing service. The pricing service may use standard inputs, such

64 OAKMARK FUNDS

Oakmark Funds

Notes to Financial Statements (continued)

as benchmark yields, reported trades, broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data, including market research publications. For certain security types, additional inputs may be used or some of the standard inputs may not be applicable. Additionally, the pricing service monitors market indicators and industry and economic events, which may serve as a trigger to gather and possibly use additional market data. Options are valued at the mean of the most recent bid and asked quotations. In the event an option is out-of-the-money and no bid is available, a zero value may be assumed as the bid for purposes of calculating the mean of the most recent bid and ask quotations. In the event that designated pricing vendors are unable to provide valuations or timely valuations for FLEX options on a given day, each FLEX option purchased or written may be valued using the Option Valuation (OVME) function on Bloomberg. The OVME function requires objective inputs (strike price, exercise style and expiration dates) to derive a valuation using Bloomberg's proprietary calculations. FLEX options shall be valued at the mid of the buy and sell valuations produced by OVME. If values or prices are not readily available or are deemed unreliable, or if an event that is expected to affect the value of a portfolio security occurs after the close of the primary market or exchange on which that security is traded and before the close of the NYSE, the security will be valued at a fair value determined in good faith in accordance with Fund policies and procedures approved by the Board. The Funds may use a systematic fair valuation model provided by an independent pricing service to value securities of non-U.S. issuers in order to adjust for changes in value that may occur between the close of certain foreign exchanges and the NYSE. All assets and liabilities initially expressed in foreign currencies are converted into U.S. dollars at a current exchange price quoted by an independent pricing service or any major bank or dealer. If such quotations are not available, the rate of exchange will be determined in good faith in accordance with Fund policies and procedures. Although fair valuation may be more commonly used with equity securities of non-U.S. issuers, it also may be used in a range of other circumstances, including thinly-traded domestic securities or fixed-income securities. When fair value pricing is employed, the value of a portfolio security used by a Fund to calculate its NAV may differ from quoted or published prices for the same security.

Fair value measurement

Various inputs are used in determining the value of each Fund's investments. These inputs are prioritized into three broad levels as follows:

Level 1—quoted prices in active markets for identical securities

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk and others)

Level 3—significant unobservable inputs (including the assumptions of Harris Associates L.P. (the "Adviser") in determining the fair value of investments)

Observable inputs are those based on market data obtained from independent sources and unobservable inputs reflect the Adviser's own assumptions based on the best information available. The input levels are not necessarily an indication of risk or liquidity associated with investing in those securities.

The following is a summary of the inputs used as of March 31, 2020, in valuing each Fund's assets and liabilities. Except for the industries or investment types separately stated below, the total amounts for common stocks, fixed income and short-term investments in the table below are presented by industry or investment type in each Fund's Schedule of Investments. Information on forward foreign currency contracts is presented in each Fund's Schedule of Investments.

Offsetting assets and liabilities

ASC 210 requires entities to disclose gross and net information about instruments and transactions eligible for offset on the Statement of Assets and Liabilities and disclose instruments and transactions subject to master netting or similar agreements. This disclosure is limited to derivative instruments, repurchase and reverse repurchase agreements, and securities borrowing and lending transactions.

At March 31, 2020, certain Funds held open forward foreign currency contracts that were subject to a foreign exchange settlement and netting agreement with the same counterparty. The agreement includes provisions for general obligations, representations and certain events of default or termination. The agreement includes provisions for netting arrangements that may reduce credit risk and counterparty risk associated with relevant transactions in the event a counterparty fails to meet its obligations. The net recognized assets or liabilities related to open forward foreign currency contracts are presented in the Statements of Assets and Liabilities. The gross recognized assets (appreciation) and liabilities (depreciation) by contract are presented in the forward foreign currency contract table included in the Fund's Schedule of Investments.

66 OAKMARK FUNDS

Oakmark Funds

Notes to Financial Statements (continued)

At March 31, 2020, each Fund held investments in repurchase agreements. The gross value of these investments and the value of the related collateral are presented in each Fund's Schedule of Investments. The value of the related collateral for each Fund exceeded the value of the repurchase agreements held at period end.

The value of the securities on loan and the value of the related collateral as of period end, if any, are included in the Securities lending section of Note 1 to Financial Statements.

Foreign currency translations

Certain Funds invest in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. Values of investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at current exchange rates obtained by a recognized bank, dealer or independent pricing service on the day of valuation. Purchases and sales of investments and dividend and interest income are converted at the prevailing rate of exchange on the respective dates of such transactions.

The Funds do not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included in net realized gain (loss) on investments and net change in unrealized appreciation (depreciation) on investments in the Statements of Operations. Net realized gains and losses on foreign currency transactions arising from the sale of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions and the difference between the amounts of dividends, interest and tax reclaims recorded and the U.S. dollar equivalent of the amounts actually received or paid are included in net realized gain (loss) on foreign currency transactions in the Statements of Operations. Unrealized gains and losses arising from changes in the fair value of assets and liabilities, other than investments in securities, resulting from changes in exchange rates are included in net change in unrealized appreciation (depreciation) on foreign currency translation in the Statements of Operations.

Forward foreign currency contracts

Forward foreign currency contracts are agreements to exchange one currency for another at a future date and at a specified price. The Funds' transactions in forward foreign currency contracts are limited to transaction and portfolio hedging. The contractual amounts of forward foreign currency contracts do not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered and could exceed the net unrealized value shown in the tables below. Risks arise from the possible inability of counterparties to meet the terms of their contracts and from movements in currency values. Forward foreign currency contracts are valued at the current day's interpolated foreign exchange rates. Unrealized gain or loss on the contracts, as measured by the difference between the forward foreign exchange rates at the dates of entry into the contracts and the forward rates at the end of the period, is included in the Statements of Assets and Liabilities. Realized gains and losses and the net change in unrealized appreciation (depreciation) on forward foreign currency contracts for the period are included in the Statements of Operations.

At March 31, 2020, Global, Global Select, International and Int'l Small Cap held non-collateralized, forward foreign currency contracts, which are considered derivative instruments, each of whose counterparty is State Street Bank and Trust Company ("State Street") and are listed in the Fund's Schedule of Investments.

For the period ended March 31, 2020, the notional value of forward foreign currency contracts opened and the notional value of settled contracts is listed by Fund in the table below (in thousands):

Fund	Currency Contracts Opened		Currency Contracts Settled
Global	$	17,555	$	25,711
Global Select		28,980		49,597
International		247,526		419,037
Int'l Small Cap		12,502		24,323

Security transactions and investment income

Security transactions are accounted for on the trade date (date the order to buy or sell is executed) and dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities are recorded as soon as the information becomes available after the ex-dividend date. Interest income and expenses are recorded on an accrual basis. Discount is accreted on long-term fixed income securities using the yield-to-maturity method. Premium is amortized on long-term fixed income securities using the yield-to-earliest call method. Withholding taxes and tax reclaims on foreign dividends have been provided for in accordance with the Funds' understanding of the applicable country's tax rules and rates. Net realized gains and losses on investments are determined by the specific identification method.

Short sales

Each Fund may sell a security it does not own in anticipation of a decline in the fair value of that security. When a Fund sells a security short, it must borrow the security sold short and deliver it to the broker-dealer through which it made the short sale. A gain, limited to the price at which the Fund sold the security short, or loss, unlimited in size, will be recognized upon the termination of the short sale. Each Fund may sell shares of when-issued securities. Typically, a Fund sells when-issued securities when a company announces a spin-off or re-organization, and the post-spin-off or post-re-organization shares begin trading on a

Oakmark.com 67

Oakmark Funds

Notes to Financial Statements (continued)

when-issued basis prior to the effective date of the corporate action. A sale of a when-issued security is treated as a short sale for accounting purposes. After the effective date, when shares of the new company are received, any shares sold on a when-issued basis will be delivered to the counterparty. At March 31, 2020, none of the Funds had short sales.

When-issued or delayed-delivery securities

Each Fund may purchase securities on a when-issued or delayed-delivery basis. Although the payment and interest terms of these securities are established at the time a Fund enters into the commitment, the securities may be delivered and paid for a month or more after the date of purchase when their value may have changed. A Fund makes such commitments only with the intention of actually acquiring the securities, but may sell the securities before the settlement date if the Adviser deems it advisable for investment reasons. At March 31, 2020, none of the Funds held when-issued securities.

Accounting for options

When a Fund writes an option, the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current fair value of the option written. Premiums received from writing options that expire are recorded by the Fund on the expiration date as realized gains from option transactions. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security or currency in determining whether the Fund has realized a gain or a loss. If a put option is exercised, the premium reduces the cost basis of the security or currency purchased by the Fund. In writing an option, the Fund bears the market risk of an unfavorable change in the price of the security or currency underlying the written option. As the writer of a covered call option on a security, a Fund foregoes, during the option's life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the exercise price of the call. Exercise of an option written by the Fund could result in the Fund selling or buying a security or currency at a price different from the current fair value. Options written by the Fund do not give rise to counterparty credit risk, as they obligate the Fund, not its counterparties, to perform.

When a Fund purchases an option, the premium paid by the Fund is recorded as an asset and is subsequently adjusted to the current fair value of the option purchased. Purchasing call options tends to increase the Fund's exposure to the underlying instrument. Purchasing put options tends to decrease the Fund's exposure to the underlying instrument. Premiums paid for purchasing options that expire are treated as realized losses. Premiums paid for purchasing options that are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying security to determine the realized gain or loss. The risks associated with purchasing put and call options are potential loss of the premium paid and, in the instances of OTC derivatives, the failure of the counterparty to honor its obligation under the contract.

Oakmark, Global Select, and Select used purchased options for tax management purposes during the period ended March 31, 2020. Oakmark, Global Select, and Select had (in thousands) net realized losses on purchased options of $34,030, $2,567 and $9,125, respectively. There were no outstanding purchased options as of March 31, 2020.

Oakmark, Global Select, and Select used options written for tax management purposes during the period ended March 31, 2020. Oakmark, Global Select, and Select had (in thousands) net realized losses on written options of $46,727, $3,156 and $19,051, respectively. Written options outstanding, if any, are listed on each Fund's Schedule of Investments.

Credit facility

The Trust has a $200 million committed unsecured line of credit and a $300 million uncommitted unsecured discretionary demand line of credit (the "Facility") with State Street. Borrowings under the Facility bear interest at 1.25% above the greater of the Federal Funds Effective Rate or LIBOR, as defined in the credit agreement. To maintain the Facility, an annualized commitment fee of 0.20% on the unused committed portion is charged to the Trust. Fees and interest expense, if any, related to the Facility are included in other expenses in the Statements of Operations. There were no borrowings under the Facility during the period ended March 31, 2020.

Expense offset arrangement

State Street serves as custodian of the Funds. State Street's fee may be reduced by credits that are an earnings allowance calculated on the average daily cash balances each Fund maintains with State Street. Credit balances used to reduce the Funds' custodian fees, if any, are reported as a reduction of total expenses in the Statements of Operations. During the period ended March 31, 2020, none of the Funds received an expense offset credit.

Repurchase agreements

Each Fund may invest in repurchase agreements, which are short-term investments whereby the Fund acquires ownership of a debt security and the seller agrees to repurchase the security at a future date at a specified price.

The Funds' custodian receives delivery of the underlying securities collateralizing repurchase agreements. It is the Funds' policy that the value of the collateral be at least equal to 102% of the repurchase price, including interest. The Adviser is responsible for determining that the value of the collateral is at all times at least equal to 102% of the repurchase price, including interest. Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty, including possible delays or restrictions upon a Fund's ability to dispose of the underlying securities. At March 31, 2020, all of the Funds held repurchase agreements.

Security lending

Each Fund may lend its portfolio securities to broker-dealers and banks. Any such loan must be continuously secured by collateral in cash, cash equivalents or U.S. Treasury or agency securities maintained on a current basis in an amount at least equal to the fair value of the securities loaned by a Fund. The Fund would continue to receive the equivalent of the interest or dividends paid by the issuer on the securities loaned and would also receive an additional return that may be in the form of a fixed fee or a percentage of the earnings on the collateral. The Fund has the right to call the loan and attempt to obtain the securities loaned at any time on notice of not more than five business days. In the event of bankruptcy or other default of the borrower, the Fund could experience delays in liquidating the loan collateral or recovering the loaned securities and incur expenses related to enforcing its rights. There could also be a decline in the value of the collateral or in the fair value of the securities loaned while the Fund seeks to enforce its rights thereto and the Fund could experience subnormal levels of income or lack of access to income during that period. A Fund may not exercise proxy voting rights for a security that is on loan if it is unable to recall the security prior to the record date. The Trust, on behalf of the Funds, has entered into an agreement with State Street to serve as its agent for the purpose of lending securities and maintaining the collateral account. Security lending income, if any, net of any fees retained by the securities lending agent, is included in the Statement of Operations.

At March 31, 2020, none of the Funds had securities on loan.

Interfund lending

Pursuant to an exemptive order issued by the SEC, the Funds may participate in an interfund lending program. This program provides an alternative credit facility that allows the Funds to lend money to, and borrow money from, each other for temporary purposes (an "Interfund Loan"). All Interfund Loans are subject to conditions pursuant to the SEC exemptive order designed to ensure fair and equitable treatment of participating Funds. Any Interfund Loan would consist only of uninvested cash reserves that the lending Fund otherwise would invest in short-term repurchase agreements or other short-term instruments. There were no interfund loans during the period ended March 31, 2020.

2. TRANSACTIONS WITH AFFILIATES

Each Fund has an investment advisory agreement with the Adviser. For management services and facilities furnished, the Adviser receives from each Fund a monthly fee based on that Fund's net assets at the end of the preceding month. Annual fee rates are as follows:

Fund				Advisory Fees
Oakmark				1.00% up to $2 billion; 0.90% on the next $1 billion; 0.80% on the next $2 billion; 0.75% on the next $2.5 billion; 0.675% on the next $2.5 billion; 0.625% on the next $2.5 billion; 0.620% on the next $12.5 billion; 0.615% on the next $10 billion; and 0.610% over $35 billion

International				1.00% up to $2 billion; 0.95% on the next $1 billion; 0.85% on the next $2 billion; 0.825% on the next $2.5 billion; 0.815% on the next $3.5 billion; 0.805% on the next $5.5 billion; 0.80% on the next $6.5 billion; 0.795% on the next $7 billion; 0.790% on the next $5 billion; 0.785% on the next $10 billion; 0.775% on the next $5 billion; and 0.770% over $50 billion
Int'l Small Cap				1.25% up to $500 million; 1.10% on the next $1 billion; 1.05% on the next $2 billion; 1.025% on the next $1.5 billion; and 1.00% over $5 billion

The Adviser has contractually agreed, through January 27, 2021, to waive the advisory fee otherwise payable to it by the following percentages with respect to each Fund: 0.043% for Oakmark; 0.074% for Select; 0.099% for Equity and Income; 0.059% for Global; 0.066% for Global Select; and 0.052% for International. When determining whether a Fund's total expenses exceed the additional contractual expense cap described below, a Fund's net advisory fee, reflecting application of the advisory fee waiver, will be used to calculate a Fund's total expenses. The Adviser is not entitled to collect on or make a claim for waived fees that are the subject of

Oakmark Funds

Notes to Financial Statements (continued)

this undertaking at any time in the future. This arrangement may only be modified or amended with approval from a Fund and the Adviser. The advisory fees waived for each Fund are included in the Statement of Operations.

The Adviser has contractually agreed, through January 27, 2021, to reimburse each Fund Class to the extent, but only to the extent that the annualized expenses (excluding taxes, interest, all commissions and other normal charges incident to the purchase and sale of portfolio securities, and extraordinary charges such as litigation costs, but including fees paid to the Adviser) exceed the percent set forth below of average daily net assets of each Fund Class.

Fund	Investor Class			Advisor Class			Institutional Class			Service Class
Oakmark		1.50	%		1.40	%		1.30	%		1.75	%
Select		1.50			1.40			1.30			1.75
Equity and Income		1.00			0.90			0.80			1.25
Global		1.75			1.65			1.55			2.00
Global Select		1.75			1.65			1.55			2.00
International		2.00			1.90			1.80			2.25
Int'l Small Cap		2.00			1.90			1.80			2.25

The Adviser is entitled to recoup from assets attributable to any Fund Class amounts reimbursed to that Fund Class, except to the extent that the Fund Class already has paid such recoupment to the Adviser or such recoupment would cause that Class' total operating expenses to exceed the expense limitation or to exceed any lower limit in effect at the time of recoupment. Any such repayment must be made within three fiscal years after the year in which the reimbursement occurred. As of March 31, 2020, there were no amounts subject to recoupment.

The Adviser and/or the Funds have entered into agreements with financial intermediaries to provide recordkeeping, processing, shareholder communications and other services to customers of the intermediaries and have agreed to compensate the intermediaries for providing those services. Certain of those services would be provided by the Funds if the shares of those customers were registered directly with the Funds' transfer agent. Accordingly, the Funds pay a portion of the intermediary fees pursuant to an agreement with the Adviser and the Adviser pays the remainder of the fees. The fees incurred by the Funds are reflected as other shareholder servicing fees in the Statements of Operations.

The Independent Trustees of the Trust may participate in the Trust's Deferred Compensation Plan for Independent Trustees. Participants in the plan may elect to defer all or a portion of their compensation. Amounts deferred are retained by the Trust and represent an unfunded obligation of the Trust. The value of a participant's deferral account is determined by reference to the change in value of Institutional Class shares of one or more of the Funds or a money market fund as specified by the participant. Benefits would be payable after a stated number of years or retirement from the Board of Trustees. The accrued obligations of the Funds under the plan are reflected as deferred Trustee compensation in the Statements of Assets and Liabilities. The change in the accrued obligations for the period is included in Trustees' fees in the Statements of Operations. The Trust pays the compensation of the Trustees other than those affiliated with the Adviser and all expenses incurred in connection with their services to the Trust. The Trust does not provide any pension or retirement benefits to its Trustees.

The Funds reimburse the Adviser for a portion of the compensation paid to the Funds' Chief Compliance Officer ("CCO"). The CCO expenses incurred by the Funds are included in other expenses in the Statements of Operations.

3. FEDERAL INCOME TAXES

It is each Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its net taxable income, including any net realized gains on investments, to its shareholders. Therefore, no federal income tax provision is required. The Adviser has determined that no income tax provision for uncertain tax positions is required in the Funds' financial statements. Generally, each of the tax years in the four-year period ended March 31, 2020, remains subject to examination by taxing authorities.

At March 31, 2020, the cost of investments for federal income tax purposes and related composition of unrealized gains and losses for each Fund were as follows (in thousands):

Fund	Cost of Investments for Federal Income Tax Purposes		Gross Unrealized Appreciation		Gross Unrealized (Depreciation)			Net Unrealized Appreciation (Depreciation)
Oakmark	$	9,317,786	$	2,288,478	$	(1,371,956	)	$	916,522

Int'l Small Cap		4,834		0		0		23,599		97,332

On March 31, 2020, the Funds had temporary book/tax differences in undistributed earnings that were primarily attributable to trustee deferred compensation expenses, passive foreign investment companies, foreign currency contracts and deferrals of capital losses on wash sales. Temporary differences will reverse over time. The Funds have permanent differences in book/tax undistributed earnings primarily attributable to equalization debits and distribution re-designations. Permanent differences are recorded in their respective component of the Analysis of Net Assets for the six-month period ended March 31, 2020.

During the six-month period ended March 31, 2020, the following amounts were classified due to permanent differences between book and tax accounting (in thousands):

	Oakmark		Select		Equity & Income		Global		Global Select		International		Int'l Small Cap
Purchases	$	1,722,717	$	661,682	$	727,797	$	172,111	$	245,195	$	4,690,094	$	277,716

5. INVESTMENTS IN AFFILIATED ISSUERS

A company was considered to be an affiliate of a Fund because that Fund owned 5% or more of the company's voting securities during all or part of the six-month period ended March 31, 2020. Purchase and sale transactions and dividend and interest income earned during the period on these securities are listed after the applicable Fund's Schedule of Investments.

6. SUBSEQUENT EVENTS

The Adviser has evaluated the possibility of subsequent events existing in the Funds' financial statements. The Adviser has determined that there are no material events that would require adjustment or disclosure in the Funds' financial statements through the date of the publication of this report.

The continued impact of the coronavirus pandemic ("COVID-19") on the financial results of each Fund will depend on future developments, including the duration and spread of COVID-19 and related advisories and restrictions. COVID-19 has resulted, and may continue to result, in significant market volatility, exchange trading suspensions and closures, global financial market declines, higher default rates, and substantial economic downturn in economies throughout the world. These developments and the impact of COVID-19 on the financial markets and the overall economy are highly uncertain and cannot be predicted. The effects of COVID-19 may materially impact the value and performance of each Fund, its ability to buy and sell fund investments at appropriate valuations, and its ability to achieve its investment objectives. If the financial markets and/or the overall economy are impacted for an extended period, the future financial results of each Fund may be materially adversely affected.

The Oakmark Funds Disclosure Regarding the Board of Trustees' Approval of Investment Advisory Agreements As Approved October 23, 2019

On an annual basis, the Board of Trustees (the "Board" or "Trustees") of the Oakmark Funds (the "Funds"), including a majority of the Trustees who are not "interested persons" of Harris Associates L.P., the Funds' investment adviser (the "Adviser") or the Funds ("Independent Trustees"), considers whether to continue each Fund's investment advisory agreement (each, an "Agreement," and collectively, the "Agreements") with the Adviser. At a meeting held on October 23, 2019, the Board, including all of the Independent Trustees, determined that the continuation of the Agreement for each Fund was in the best interest of the Fund and its shareholders, and approved the continuation of each Agreement through October 31, 2020.

The Board's Committee on Contracts (the "Committee") leads the Board in its evaluation of the Agreements. The Committee is comprised entirely of Independent Trustees, and more than 75% of the Board is comprised of Independent Trustees. The Committee, together with the other Independent Trustees, requested, received, reviewed and considered materials provided by the Adviser in response to questions submitted by the Independent Trustees that they believed to be relevant to the continuation of the Agreements with respect to each Fund in light of legal advice furnished to them by their legal counsel that is experienced in Investment Company Act of 1940 matters and that is independent from the Adviser ("Independent Counsel"); their own business judgment; and developments in the industry, the markets and mutual fund regulation and litigation. During the annual contract approval process, the Committee and the other Independent Trustees met multiple times specifically to review and consider materials related to the proposed continuation of each Agreement; and to ensure that the Adviser had time to respond to questions from the Independent Trustees and that the Independent Trustees had time to consider those responses. They also met with senior representatives of the Adviser regarding, among other things, its personnel, operations and financial condition as they relate to the Funds. In addition, the Board retained Broadridge Financial Solutions, Inc. ("Broadridge"), an independent consulting firm that specializes in the analysis of fund industry data, to provide performance and expense information for each Fund and a peer group of comparable funds, as selected by Broadridge. The Board also met with Broadridge representatives to request certain additional information and again to follow up on specific questions regarding data provided. While the Board considered the continuation of the Agreements for all of the Funds at the same meetings, the Board considered each Fund's Agreement separately from those of each other Fund.

In connection with its deliberations, the Board also considered a broad range of information relevant to the annual contract approval process that is provided to the Board (including its various standing committees) at meetings throughout the year, including investment performance reports and related portfolio information for each Fund, as well as reports on, among other matters, pricing and valuation; quality and cost of portfolio trade execution; compliance; and shareholder support and other services provided by the Adviser and its affiliates.

The Independent Trustees were advised by Independent Counsel throughout the annual contract approval process and they received a memorandum from Independent Counsel discussing the legal standards for their consideration of the proposed continuation of the Agreements. During the course of the year and during their deliberations regarding the annual contract approval process, the Committee and the other Independent Trustees met with Independent Counsel separately from representatives of the Adviser.

Provided below is a description of the Board's annual contract approval process and material factors that the Board considered regarding continuation of the Agreements and the compensation to be paid thereunder. The Board's determination to approve the continuation of the Agreements was based on a comprehensive consideration of all information provided to the Board throughout the year and specifically in connection with the annual contract approval process.

This description is not intended to include all of the factors considered by the Board. The Trustees did not identify any particular information or factor that was all-important or controlling, and each Trustee may have attributed different weights to the various factors. The Board focused on the costs and benefits of the Agreements to each Fund and, through the Fund, its shareholders.

Nature, Extent and Quality of Services

The Board's consideration of the nature, extent and quality of the Adviser's services to the Funds took into account the knowledge the Board gained during meetings with the Adviser throughout the year. In addition, the Board considered: the Adviser's long-term history of care and conscientiousness in the management of the Funds; the consistency of its investment approach; the qualifications, experience and capabilities of, and the resources available to, the Adviser's investment and other personnel responsible for managing the Funds; the Adviser's performance as administrator of the Funds; and the Adviser's compliance program. The Board also considered the Adviser's resources and reviewed key personnel involved in providing investment management services to the Funds, including the time that investment personnel devoted to each Fund, and the investment results produced as a result of the Adviser's in-house research. The Trustees also reviewed information regarding each Fund's "active share" in relation to its benchmark index.

The Board noted the extensive range of services that the Adviser provides to the Funds beyond the investment management services. The Board considered that, pursuant to each Agreement, the Adviser provides administrative services, including, among others, oversight of shareholder communications, fund administration and accounting services, regulatory and legal obligation oversight, supervision of Fund operations and Board support. The Board noted that the Adviser is also responsible for monitoring compliance with each Fund's investment objectives, policies and restrictions, as well as compliance with applicable law, including implementing rulemaking initiatives of the U.S. Securities and Exchange Commission. The Board also considered that the Adviser's responsibilities include continual management of investment, operational, enterprise, legal, regulatory and compliance risks as they relate to the Funds, and on a regular basis it considers information regarding the Adviser's processes for monitoring and managing risk. The Board also noted the Adviser's oversight of the Funds' various outside service providers, including its negotiation of certain service providers' fees and its evaluation of service providers' infrastructure, cybersecurity programs, compliance programs and business continuity programs, among other matters. The Board also considered the Adviser's ongoing development of its own internal infrastructure, including, among other things, its operational and trading capabilities, and its information technology to support the

88 OAKMARK FUNDS

Funds' compliance structure through, among other things, cybersecurity programs, business continuity planning and risk management. In addition, the Board noted the positive compliance history of the Adviser.

The Board also considered the general structure of the Adviser's compensation program for portfolio managers, analysts and certain other employees, and whether this structure provides appropriate incentives to act in the best interests of the Funds. In addition, the Board considered the ability of the Adviser to attract and retain qualified personnel to service the Funds. The Board also noted the significant personal investments that the Adviser's personnel have made in the Funds, which serve to further align the interests of the Adviser and its personnel with those of the Funds' shareholders.

The Board also considered the manner in which the Adviser addressed various matters that arose during the year. These matters may have been the result of developments in the broader fund industry or the regulations governing it, including, for example, the liquidity risk management program rules and subsequent amendments. In addition, the Board considered the Adviser's response to recent market conditions and considered the overall performance of the Adviser in this context.

Investment Performance of the Funds

The Board considered each Fund's investment performance over various time periods, net of the Fund's fees and expenses, both on an absolute basis and compared to the performance of a broader group of comparable funds pursuing generally similar strategies with the same investment classification and/or objective as each Fund (the Fund's "Performance Universe"), as selected by Broadridge. The Board also considered the quintile ranking of each Fund against its Performance Universe. As a general matter, the Board considered each Fund's performance and fees in light of the limitations inherent in the methodology for constructing such comparative groups and determining which investment companies should be included in the comparative groups. Because the Committee commenced its review of the investment performance of the Funds in June, the performance periods considered by the Board were those ended April 30, 2019. The Board considered the 1-, 3-, 5- and 10-year performance for each Fund. The Board also considered updated performance information at its October meeting at which the Agreements were approved.

Further detail considered by the Board regarding the investment performance of each Fund is set forth below:

Oakmark Fund. The Board considered that the Oakmark Fund underperformed the median annualized returns of its respective Performance Universe during the 1- and 5-year periods ending April 30, 2019, but outperformed the median annualized returns of its respective Performance Universe during the 3- and 10-year periods ending April 30, 2019.

Oakmark Select Fund. The Board considered that the Oakmark Select Fund underperformed the median annualized returns of its respective Performance Universe during the 1-, 3- and 5-year periods ending April 30, 2019, but outperformed the median annualized return of its respective Performance Universe during the 10-year period ending April 30, 2019.

Oakmark Equity and Income Fund. The Board considered that the Oakmark Equity and Income Fund outperformed the median annualized returns of its respective Performance Universe during the 1-, 3-, 5- and 10-year periods ending April 30, 2019.

Oakmark Global Fund. The Board considered that the Oakmark Global Fund underperformed the median annualized return of its respective Performance Universe during the 1-year period ending April 30, 2019, but outperformed the median annualized returns of its respective Performance Universe during the 3-, 5- and 10-year periods ending April 30, 2019.

Oakmark Global Select Fund. The Board considered that the Oakmark Global Select Fund underperformed the median annualized return of its respective Performance Universe during the 1-year period ending April 30, 2019, was the same as the median annualized return of its respective Performance Universe during the 3-year period ending April 30, 2019, but outperformed the median annualized returns of its respective Performance Universe during the 5- and 10-year periods ending April 30, 2018.

Oakmark International Fund. The Board considered that the Oakmark International Fund underperformed the median annualized return of its respective Performance Universe during the 1-year period ending April 30, 2019, but outperformed the median annualized returns of its respective Performance Universe during the 3-, 5- and 10-year periods ending April 30, 2019.

Oakmark International Small Cap Fund. The Board considered that the Oakmark International Small Cap Fund underperformed the median annualized returns of its respective Performance Universe during the 3-, 5- and 10-year periods ending April 30, 2019, but outperformed the median annualized return of its respective Performance Universe during the 1-year period ending April 30, 2019.

In addition to considering each Fund's performance as compared to that of its respective Performance Universe, the Board also considered each Fund's performance as compared to that of its benchmark, and other comparative data provided by Broadridge, including each Fund's total return and performance relative to risk, and separate comparative data provided by the Adviser. The Board met quarterly with the portfolio managers of each Fund to discuss the Fund's performance during the 12 months prior to voting on the contract renewal. For each Fund with periods of underperformance as compared to its Performance Universe, that the Board believed warranted further inquiry, the Board discussed with the Adviser the factors that caused such underperformance and how the Adviser evaluates underperformance relative to Fund peers. The Board considered the Adviser's responses with respect to each Fund that experienced underperformance.

Costs of Services Provided and Profits Realized by the Adviser

The Board considered the fee structure for each Fund under its Agreement as compared to the peer group provided by Broadridge, including funds that the Adviser identified as comparable peer funds. Specifically, using the information provided by Broadridge, the Board considered each Fund's management fee and the management fees for other mutual funds comparable in fund type, investment classification/objective, load type and asset size to each Fund (the Fund's "Expense Group"), and considered each Fund's total expense ratio, which reflects the total fees paid by an investor, and those of its Expense Group.

Further detail considered by the Board regarding each Fund's management fee and total expense ratio as of the conclusion of its fiscal year ended September 30, 2018, is set forth below:

Oakmark Fund. The Board considered that the Oakmark Fund's management fee net of fees waived by the Adviser was higher than the median of its respective Expense Group and the Fund's total expense ratio was lower than the median of its respective Expense Group.

Oakmark.com 89

Oakmark Select Fund. The Board considered that the Oakmark Select Fund's management fee net of fees waived by the Adviser and the Fund's total expense ratio were both higher than the corresponding medians of its respective Expense Group.

Oakmark Equity and Income Fund. The Board considered that the Oakmark Equity and Income Fund's management fee net of fees waived by the Adviser and the Fund's total expense ratio were both higher than the corresponding medians of its respective Expense Group.

Oakmark Global Fund. The Board considered that the Oakmark Global Fund's management fee net of fees waived by the Adviser and the Fund's total expense ratio were both higher than the corresponding medians of its respective Expense Group.

Oakmark Global Select Fund. The Board considered that the Oakmark Global Select Fund's management fee net of fees waived by the Adviser was higher than the median of its respective Expense Group and the Fund's total expense ratio was lower than the median of its respective Expense Group.

Oakmark International Fund. The Board considered that the Oakmark International Fund's management fee net of fees waived by the Adviser and the Fund's total expense ratio were both lower than the corresponding medians of its respective Expense Group.

Oakmark International Small Cap Fund. The Board considered that the Oakmark International Small Cap Fund's management fee net of fees waived by the Adviser and the Fund's total expense ratio were both higher than the corresponding medians of its respective Expense Group.

The Board also reviewed the Adviser's management fees for comparable institutional separate account clients and sub-advised funds (for which the Adviser provides portfolio management services only). The Board considered the appropriateness and reasonableness of any differences between the fees charged to a Fund and any such comparable separate account clients and/or sub-advised funds, including any breakpoints, and noted the Adviser's explanation that, although in most instances the fees paid by those other clients were lower than the fees paid by the Funds, the differences reflected the Adviser's significantly greater level of responsibilities and broader scope of services with respect to the Funds. The Board further noted the more extensive regulatory obligations and the various risks (e.g., operational, enterprise, legal, regulatory, compliance) associated with managing the Funds as compared to any such comparable separate account clients and/or sub-advised funds.

The Board also noted that each Fund's management fee is a single fee that compensates the Adviser for its services as investment adviser and manager under the Agreements, and further noted that, for comparative purposes, where possible, Broadridge aggregated the separate investment advisory and administrative fees into a single management fee for the mutual funds in the Expense Group that clearly identify two separate fees. The Board noted that some mutual funds in the Expense Group may pay directly from fund assets for certain services that the Adviser is compensated for out of the management fee for the Funds. Accordingly, the Board also considered each Fund's total expense ratio as compared with its respective Expense Group as a way of taking account of these differences. The Board also considered the Adviser's agreement to continue the expense limitation agreement for each Fund. In addition, the Board considered the Adviser's agreement to continue the investment advisory fee waiver agreement for Oakmark Fund, Oakmark Select Fund, Oakmark Equity and Income Fund, Oakmark Global Fund, Oakmark Global Select Fund and Oakmark International Fund.

The Board also considered the Adviser's costs in serving as the Funds' investment adviser and manager, including costs associated with technology, infrastructure and compliance necessary to manage the Funds. Finally, the Board considered the Adviser's profitability analysis, as well as an Investment Management Industry Profitability Analysis prepared by Broadridge. The Board examined the estimated pre-tax profits realized by the Adviser and its affiliates from their relationship with each Fund, as presented in the profitability analyses, as well as the financial condition of the Adviser. The Board reviewed the Adviser's methodology for allocating costs among the Adviser's lines of business and among the Funds, for purposes of calculating its estimated profitability, and recognized that the methodology may not reflect all of the costs or risks associated with offering and managing a mutual fund complex. The Board also recognized that the Adviser and its affiliates are entitled to earn a reasonable level of profits for services they provide to each Fund.

Economies of Scale

The Board considered whether each Fund's management fee structure reflects any potential economies of scale that may be realized by the Adviser for the benefit of each Fund's shareholders. The Board reviewed each Agreement, which includes breakpoints that decrease the management fee rate as Fund assets increase. In addition, the Board considered each Fund's expense limitation agreement and the investment advisory fee waiver agreement for Oakmark Fund, Oakmark Select Fund, Oakmark Equity and Income Fund, Oakmark Global Fund, Oakmark Global Select Fund and Oakmark International Fund that reduces each Fund's expenses at all asset levels, which can have an effect similar to breakpoints in sharing economies of scale with shareholders and provides protection from an increase in expenses if a Fund's assets decline. The Board also considered that the Adviser has provided, at no added cost to the Funds, certain additional services, including but not limited to, services required by new regulations or regulatory interpretations, services impelled by changes in the securities markets or the business landscape and/or services requested by the Board. The Board considered that this is a way of sharing economies of scale with the Funds and their shareholders.

Other Benefits Derived from the Relationship with the Funds

The Board considered any fall-out benefits likely to accrue to the Adviser or its affiliates from their relationship with each Fund. The Board noted that an affiliate of the Adviser serves as the Funds' distributor, without compensation, pursuant to a written agreement the Board evaluates annually. The Board also considered the Adviser's use of a portion of the commissions paid by the Funds on their portfolio brokerage transactions to obtain research and brokerage products and services benefiting the Funds and/or other clients of the Adviser, and considered the Adviser's assertion that its use of "soft" commission dollars to obtain research and brokerage products and services was consistent with regulatory requirements.

Conclusion

After full consideration of the above factors, as well as other factors that were instructive in evaluating the Agreements, the Board, including all of the Independent Trustees, in its business judgment, concluded that approval of the continuation of each Agreement was in the best interests of the respective Fund and its shareholders. In reaching this determination, the Board considered that the nature, extent and quality of the services provided by the Adviser to each Fund were appropriate and consistent with the Fund's Agreement and that each Fund was likely to continue to benefit from services provided under its Agreement with the Adviser; that the Adviser was delivering performance for each Fund that was consistent with the long-term investment strategies being pursued by the Fund, and that the Fund and its shareholders were benefiting from the Adviser's investment management of the Fund; that the management fees paid by each Fund to the Adviser were reasonable in light of the services provided; that the breakpoints in the fee schedule for each Fund allow shareholders to benefit from potential economies of scale that may be achieved by the Adviser; that the profitability of the Adviser's relationship with each Fund appeared to be reasonable in relation to the services performed; and that the benefits accruing to the Adviser and its affiliates by virtue of their relationship with the Funds were reasonable in light of the costs and risks associated with providing the investment advisory and other services to each Fund and the benefits accruing to each Fund. The Board's conclusions are based in part on its consideration of materials prepared in connection with the approval or continuance of the Agreements in prior years and on the Board's ongoing regular review of Fund performance and operations throughout the year, in addition to material prepared specifically for the most recent annual contract approval process.

The discussion of the Funds' investments and investment strategy (including current investment themes, the portfolio managers' research and investment process, and portfolio characteristics) represents the Funds' investments and the views of the portfolio managers and Harris Associates L.P., the Funds' investment adviser, at the time of this report, and are subject to change without notice.

All Oakmark Funds: Investing in value stocks presents the risk that value stocks may fall out of favor with investors and underperform growth stocks during given periods.

Oakmark, Oakmark Equity and Income, Oakmark Global, Oakmark International, and Oakmark International Small Cap Funds: The Funds' portfolios tend to be invested in a relatively small number of stocks. As a result, the appreciation or depreciation of any one security held will have a greater impact on the Funds' net asset value than it would if the Funds invest in a larger number of securities. Although that strategy has the potential to generate attractive returns over time, it also increases the Funds' volatility.

Oakmark Select and Oakmark Equity and Income Funds: The stocks of medium-sized companies tend to be more volatile than those of large companies and have underperformed the stocks of small and large companies during some periods.

Because the Oakmark Select and Oakmark Global Select Funds are non-diversified, the performance of each holding will have a greater impact on the Funds' total return and may make the Funds' returns more volatile than a more diversified fund.

Oakmark Global, Oakmark Global Select, Oakmark International and Oakmark International Small Cap Funds: Investing in foreign securities presents risks which in some ways may be greater than U.S. investments. Those risks include: currency fluctuation; different regulation, accounting standards, trading practices and levels of available information; generally higher transaction costs; and political risks.

The percentages of hedge exposure for each foreign currency are calculated by dividing the market value of all same-currency forward contracts by the market value of the underlying equity exposure to that currency.

The Oakmark Equity and Income Fund invests in medium- and lower quality debt securities that have higher yield potential but present greater investment and credit risk than higher quality securities. These risks may result in greater share price volatility.

Oakmark International Small Cap Fund: The stocks of smaller companies often involve more risk than the stocks of larger companies. Stocks of small companies tend to be more volatile and have a smaller public market than stocks of larger companies. Small companies may have a shorter history of operations than

larger companies, may not have as great an ability to raise additional capital and may have a less diversified product line, making them more susceptible to market pressure.
