Last month, Win Murray and I had the opportunity to be interviewed by John Heins of Value Investor Insight (VII). In addition to editing VII, which we find to be one of the most interesting value investor publications, John teaches investing at the University of Alabama. We enjoy reading VII because it provides in-depth looks into different value investors' investment approaches, using individual stock examples that highlight their thought process. Below, we have excerpted a portion of our interview; the entire interview is available on our website.

We're assuming what you're looking for—stocks trading at discounts to your estimate of value, management teams aligned with shareholders, and value that grows over time—hasn't changed. True?

Bill Nygren: There hasn't been any significant change. From the time we started Oakmark Fund more than 25 years ago those have been the criteria we've used to find companies in which to invest. We still believe they're the three most important things on which to focus.

If you're missing any of those, you start to struggle with the investment idea. If the name isn't cheap, it doesn't even qualify as a value investment. If the value isn't growing, then you've got a clock that's ticking against you. And if management isn't focused on maximizing long-term per-share value, then no matter how good your analysis is of the business, the decisions being made can disrupt the rising path of value you'd otherwise see in the static business. It's only when all three of those things are present—discount to the value, value that's growing and management trying to maximize per-share value—that we have the confidence to make an investment.

Private-equity firms generally look for companies they believe investors will perceive differently five to seven years from now because of changes they can put in place. Investors today might be ignoring hidden assets or are overly focusing on a temporary problem, but a private-equity approach focuses on how business values could change over several years. That's a very different way of thinking from most investors who are trying to outguess each other on next quarter's or next year's earnings. We try to apply a private-equity approach to public-equity investing.

You invest in some of the best-known and most-followed companies in the world. What can make them mispriced?

BN: The easiest thing for investors to do is to extrapolate historical trends. The opportunities we find usually arise when that extrapolation leads to something that is very different than what we think is likely. That could come from new management and believing future margins are going to be very different than in the past. It could come from non-earning assets we believe over time will display their value. It could

come from an overreaction to what we think is a short-term negative for earnings.

Win Murray: Frequently we're coming to companies that haven't been run particularly well and because of that the investor perception is that the business itself is not very good. With Baxter International [BAX], for example, we saw a company with an operating margin of roughly half the 20% we thought was possible, with a new CEO, Jose Almeida, taking over at the beginning of last year after a very successful stint at Covidien, where we had been a shareholder. That type of situation is frequently interesting, combining a stale company perception with an executive who has a record of success. With our time horizon generally giving turnarounds time to work, you can find opportunity even in well-known companies. [Note: Baxter shares, at $38.15 when Almeida became CEO, recently traded at $59.20.]

It's more difficult than ever to distinguish between permanent and temporary issues facing companies and their industries. Describe how you deal with investments that aren't working out as expected.

BN: When an analyst makes a recommendation, he or she is presenting a model for the business—how they expect the income statement and balance sheet to change over time and what that should mean for per-share business value—that stretches out for the next five to seven years. When we get to a point where the fundamental results have deviated significantly from that plan, say by a double-digit percentage level, that triggers a process where we completely revisit our assumptions to see if we'd have enough confidence to buy it today if it were a new investment.

Investors often struggle when a business hasn't performed as expected. When do you challenge your thesis and ask yourself, was I wrong? Value investors take great pride in their patience, but for patience to be a good thing, your thesis has to be right. At some point you may have to recognize when new information presents enough of a challenge to your thesis that you should revisit whether or not this is an investment you would make today. That's the process we go through when fundamentals are negatively deviating from our thesis. Likewise if they positively deviate, which is a much more pleasant situation.

How generally do you arrive at estimates of fair value?

WM: For most of our companies we estimate a normal cash-flow level—we use earnings before interest, taxes and amortization as a short cut—and then ascribe to that a multiple that makes sense in the framework of a discounted-cash-flow model and relative to valuations on all the other names we look at. We recognize the difficulty in precisely pegging what a company is worth two to three years from now, but if we're

making our best estimates in every case and arriving at those estimates in a disciplined and consistent manner, we should be surfacing the most-attractive relative ideas for each portfolio.

I'll ask analysts, "If you had to bet your entire salary on whether or not the company will exceed or fall short of your cash-flow estimate, which way would you go?" If they're able to answer that question in either direction, then they're using the wrong number. We want them to be torn and not know if they'd bet the over or the under. Just because we're value investors doesn't mean that we want everything to be portrayed as conservatively as possible. When it comes to making portfolio-management decisions, it's the absolute value of the error that is going to cause the investment mistake, not just being too high.

What do you think the market is missing about General Electric [GE]?

WM: We like to look for management catalysts in companies that we think have a stale perception in the marketplace, and this fits that profile precisely.

We have always admired GE's businesses—we really like businesses where you sell a big piece of OEM equipment at a low margin and then collect a 40-year stream of high-margin service revenues that the customer is essentially locked into. GE has a lot of those businesses.

The problem we had with GE is that the culture of capital allocation developed under Jack Welch and continuing under Jeff Immelt was one that bought high-multiple businesses and sold low-multiple businesses in a way that destroyed shareholder value. They bought expensive healthcare, Amersham, when oil and gas was really cheap. Then they bought expensive oil and gas—Lufkin Industries, Vetco Gray, Dresser, and others—when healthcare was really cheap. They expanded financial services at the worst possible time. They sold NBC at the bottom of its ratings cycle at a very low multiple of cash flow. It was one thing after another that made us put a big discount on cash flows because of how they were being reinvested.

When Jeff Bornstein took over as GE's Chief Financial Officer in mid-2013 you can draw a line when capital stewardship changed. They bought Alstom's power-equipment business for a single-digit multiple of cash flows. They sold Synchrony Financial in a tax-efficient spinout and effectively used the proceeds to buy back shares. They sold the appliance business for a high multiple. They combined the oil and gas business with Baker Hughes at the bottom of an oil cycle in an asset-light way. They dismantled GE Capital swiftly and at a good multiple of book value. All very impressive and executed as a contrarian value investor would.

In another significant move, Bornstein drove a change in how GE's top 6,000 or so executives are paid. The new incentive system put in place at the beginning of 2016 was a complete revamp of a 1950s-era plan that was almost union-shop in construction, based more on seniority and your bonus last year than how you actually performed. The new plan pays out based on a scorecard of factors under managers' direct control and tracked in real time, and it's far more possible to get paid a lot or a little than under the old system. That's a big change we expect to have a very positive impact over time.

How well positioned do you consider GE's key operating divisions?

WM: Aviation is a powerhouse that has been taking global market share and is currently rolling out its biggest product launch ever—the LEAP jet engine developed with France's Safran—which is showing great uptake. The medical-equipment business is well positioned in its core ultrasound and imaging markets and has good growth potential in developing markets and with an expanded product line for the development of biologic drugs.

In power, while the broad segment may not grow quickly, there is significant upside for GE through cost synergies and cross-selling after the Alstom purchase. The last big piece is oil and gas. The Baker Hughes transaction filled holes in both companies' portfolios with little overlap and now the merged company has access to GE's balance sheet. Many national oil companies are resource-rich but cash poor and to develop their fields they would like to partner with an oil-field service company that can help finance the exploration and development. As the oil market recovers, the new Baker Hughes has the potential to gain share as a result.

Some analysts, citing a lower conversion of earnings into cash flow, have questioned GE's earnings quality. Is that a concern?

WM: We don't believe so. The company has been preparing for big product launches and has by design been less efficient with working capital in order to ensure smooth rollouts. We think that's fully explainable by where they are in the launch cycles and that the cash flows they're going to produce from those launches are well worth any short-term mismatch between GAAP earnings and cash flow.

Harley-Davidson [HOG] has been on value investors' radar for some time now, without much benefit. What upside do you see from here?

WM: Before we purchased the company's shares in Oakmark Select, we visited Milwaukee to meet with the CEO, Matt Levatich, who took over in May 2015. I was worried Matt would be too much of a caretaker CEO, kind of stewarding the strong brand along as it dealt with slow secular decline. We came away concluding that wasn't at all the case.

Prior management had spent a decade trying to optimize capacity for demand and improving manufacturing efficiencies. That was all well and good, but the challenge now has been to correct for years of underinvestment in new products, marketing and geographic expansion. Today they're investing more than 200 basis points of margin into marketing and new product development. They're opening dealerships in markets like China, India and Vietnam. They're marketing heavily to customers outside the traditional demographic of white males over the age of 35.

Is all that enough to compensate for traditional baby-boomer customers aging out of the market?

WM: Investors seem to be implicitly worried about the number of motorcycles current 50-to-70-year-olds will be buying in 10 to 15 years. Obviously that isn't a high number. What's more important is how many motorcycles 25-to-50-year-olds around the world will be buying in 10 to 15 years. We think that's going to be a surprisingly high number.

According to industry data, current 25-to-50-year-olds are more likely to own a motorcycle than baby-boomers were when they were that age. According to Harley, people under the age of 35 are buying more Harleys per capita than the boomers did at the same age. Internationally, it's not a question of demand for motorcycles—there are roughly eight million motorcycles in the U.S. out of 150 million worldwide—but the extent to which rising disposable incomes support the purchase of higher-end brands like Harley. We think the Harley brand is vibrant and healthy outside the U.S. as well as inside, and that it will benefit significantly as an aspirational brand. International now represents 36-37% of the company's unit volumes.

How do you handicap the competition?

WM: The most buzz is around Indian, which is Polaris's relaunched brand that has a lot of cachet among the type of rider that likes Harley. But Indian is a drop in the bucket relative to Harley, and its volumes are a long way from being large enough to incent Polaris to invest the large dollar amounts required to build significant additional Indian capacity. Our bigger worry would be competitors like Honda and Yamaha that do have the capacity.

This points to a key element of our thesis that will need constant scrutiny. We're arguing that the company is navigating a customer-base transition, but that the strength of the core brand underneath will win the day with a long-enough time horizon. If the brand isn't resonating with new customers as it has with old, that will clearly be an issue.

Are you finding it hard today to find sufficiently discounted share prices?

BN: It's always hard. When prices get to a level where they look really cheap relative to history, it's usually in the midst of a news environment that makes investors reluctant to commit long-term capital. I used to think it must have been easy to be an equity investor back in the 1950s when the dividend yield on the S&P 500¹ exceeded the yield on ten-year Treasuries. When we experienced that environment in just the past few years, it didn't seem so easy.

I think it's dangerous to draw lines in the sand after which you'll just sit it out. Once you do, the temptation is to spend all your time trying to defend why now is not the time to be invested. I wrote a piece last year on the 25th anniversary of Oakmark Fund. At the time the fund had returned something like 20x investors' initial capital, while the S&P was up 10x. But when you look at the list of things investors had to deal with over that time—wars, hurricanes, global financial crisis, oil-price collapse, just to name a few—it's amazing the market returned 10-fold. It's surprising to me how many of our peers, who share our long-term belief that equities are likely to continue to be the highest-return asset category, believe they can enhance that return by figuring out those occasional periods where the equity market is at higher risk.

You could look at the market today and say the trailing P/E² is 15-20% above historical averages, which could be enough to give one pause. On the other hand, dividend yields as a percentage of corporate bond yields are higher than normal. The economic growth outlook right now is positive. Retained earnings are higher than average and are being put to use to delever balance sheets, increase dividends and repurchase shares. There are always reasons to be bearish and there are

The Oakmark Fund increased 3.8% in the second quarter of 2017, which was ahead of the 3.1% gain for the S&P 500¹ Index. This was the fourth quarter in a row in which the Oakmark Fund hit an all-time high adjusted NAV. Broader market strength continued in the second quarter despite lingering concerns about healthcare and tax reform, as well as a drop in energy commodity prices. As was the case in the first quarter, weakening oil prices hurt the performance of our energy holdings during the second quarter, but we remain confident in the long-term outlook for these businesses. With no change in our fundamental outlook for our energy businesses, the lower share prices represented an opportunity to increase the return potential of the portfolio, and accordingly, we added to most of our energy holdings during the quarter.

Our biggest contributing sectors were financials and information technology, and our lowest contributing sectors were energy and industrials. Our top individual contributors were Citigroup, Nestlé and Alphabet. Citigroup—and many of our other financial holdings—benefited late in the quarter from generally favorable results from the Federal Reserve's capital analysis review. We are pleased that Citigroup, as well as our other financial holdings, will have greater flexibility to return capital to shareholders through higher dividends and larger share repurchase programs. Alphabet produced a total return of 10%, primarily because of strong first quarter results. The company's revenue was up over 20% during the quarter, and Alphabet disclosed that YouTube achieved one billion hours watched per day. We have said that YouTube represents a source of unappreciated value within Alphabet, and this disclosure helped to validate our thinking. Our largest detractors were Anadarko, National Oilwell Varco and General Electric. We initiated a new position in Charter Communications during the quarter, and we didn't eliminate any positions.

Charter Communications (CHTR—$331)

Charter gives us the opportunity to invest in what we believe is a strong business with exceptional management at an attractive price. Because of their valuable infrastructure, U.S. cable companies are benefiting from strong demand for high-speed Internet access. In many markets, Charter has the only fiber-rich network capable of providing consumers with the high Internet speeds they demand. We believe that new competitors are unlikely to enter the market as they will have to invest massive amounts of capital for fractional penetration. This should provide a long runway for continued growth at Charter. Chairman and CEO Tom Rutledge earned an excellent reputation for execution at Cablevision, and he has achieved meaningful progress with the legacy Charter business. Corporate governance at Charter is influenced by Dr. John Malone. We've had tremendous success investing alongside Dr. Malone over the past 30+ years, and we greatly value his strategic vision and capital allocation skills. After reporting its first quarter earnings, Charter's stock price lagged behind the market as investors appeared to be frustrated with the pace of operational improvement at Time Warner Cable. Our experience investing in turnarounds reminds us that it takes more than a couple of quarters to make meaningful progress. We take a more positive, longer term view of the business, and Charter is valued at a discount to peer companies.

The Oakmark Select Fund was up 1.9% for the quarter, trailing the S&P 500¹ Index's 3.1% return. Three quarters into our fiscal 2017, the Oakmark Select Fund has increased by 15.7%, compared to a 13.5% gain for the S&P 500 Index.

During the quarter, we added one new position to the Fund, Weatherford International. Weatherford is the fourth-largest company in the oilfield services industry. The business was built through approximately 300 acquisitions over the past 30 years. These deals provided Weatherford with many high-quality business lines, but the financial results were disappointing due to poor integration efforts, inefficient operations, losses from non-core product lines, and—most recently—the most severe oil industry downturn in a generation. The majority of these headwinds are now abating. The previous management team has been replaced by a proven industry leader with a reputation for cost cutting. The company is divesting money-losing business lines and rationalizing its bloated operations. Although oil prices are still a challenge for the service industry, activity levels have increased substantially. Over the next few years, the combination of the operational improvements and oil market recovery should lead to substantial earnings at Weatherford. We believe Weatherford represents a classic turnaround investment, and its current share price is cheap relative to our estimate of the company's future cash flows.

We eliminated our position in Intel. We still believe the stock is reasonably priced and continue to hold it in our more diversified products. However, we do not believe it meets the hurdle for inclusion in a concentrated portfolio.

Our best performer in the quarter, up 23%, was Liberty Interactive QVC. As we discussed in our third quarter 2016 letter, after the company reported an unexpected decline in sales, its stock price sagged. But management was taking actions to fix the issues, and at that time, we believed the stock had fallen far in excess of the change in underlying business value. Now, its sales declines have moderated, and growth is expected to resume later this year. The stock price has increased accordingly.

The Fund's largest holding—and consequently, the biggest contributor to our performance—was Alphabet, up 10%. The company reported excellent earnings, with sales growth greater than 20%. Please see the link to our Value Investing Insight interview for a full discussion of how we're valuing this company and why we believe it's still an attractive investment.

Our biggest detractors to performance were energy holdings: Chesapeake and the aforementioned Weatherford. Our energy positions in aggregate subtracted 2.4% from our performance this quarter, well in excess of the 1.2% by which the Fund lagged behind the S&P 500. It's easy to see that our investments here are quite out of favor. Contrary to current sentiment, however, we believe our investments in this sector are some of the

Quarter Review

Although the June quarter superficially appeared to extend trends that emerged after the presidential election, a more careful examination shows material changes in the landscape. Perhaps most striking has been the flattening of the yield curve. The yield curve simply plots the interest rates of fixed income securities with equal credit quality but differing maturities at a specific moment in time. Investors most commonly refer to the yield curve relative to U.S. Treasury issues, given that market's depth and breadth. The U.S. Federal Reserve (the Fed) heavily influences the short end of the Treasury yield curve. During the past quarter, the Fed caused the Fed Funds rate (the shortest term rate) to increase by 25 basis points or 1/4%. The longer end of the yield curve did not follow the move upward, however, resulting in the flattening mentioned above.

Former Fed Chair Alan Greenspan, observing a similar phenomenon 12 years ago, called this a "conundrum." Historically, a flattening yield curve has often been a harbinger of impending economic deceleration, and some macro investors take that position now. Others argue that historical precedent carries little weight today given the unique features of the current environment, particularly the minimal interest rates available in European or Japanese fixed income instruments. Still another explanation is that entities with very long duration liabilities are struggling to populate their portfolios with similarly long duration assets, meaning that strong demand for longer maturity assets puts a cap on their rates. Our perspective is that interest rates set the price for money and that money is priced too cheaply at today's prices. We continue to maintain a low-risk posture in the Fund's fixed income allocation, although this was not helpful to the Fund's relative results this past quarter.

For the equity market in the quarter, volatility remained low, but relative performance shifted to favor growth companies. Large capitalization issues outperformed small, with technology leading the way until the end of the quarter. Remember the FANGs (Facebook, Amazon, Netflix and Google) that dominated equity market returns in 2015? In this year's second quarter, a new acronym was coined: FAAMG (Facebook, Amazon, Apple, Microsoft and Google⁹). Through much of the quarter, the FAAMGs accounted for a substantial proportion of the S&P 500's¹ return. We believe that this occurred as investors concluded that the new administration would be unable to pass business-friendly legislation, so they moved toward dependable growth names.

The Equity and Income Fund earned 1.7% in the quarter, while the Lipper Balanced Fund Index⁷, the Fund's performance benchmark, gained 2.5%. For the calendar six months, the Fund returned 5.9%, compared to 6.8% for the Lipper. The Fund's nine-month fiscal year return was 11.2%, compared to 7.5% for the Lipper. The annualized compound rate of return

since the Fund's inception in 1995 is 10.2% while the corresponding return to the Lipper Index is 6.9%.

Nestlé, Oracle, UnitedHealth Group, FNF Group and Citigroup led the list of contributors to return for the quarter. The largest detractors were Foot Locker, Kate Spade, National Oilwell Varco, Baker Hughes and Arconic. The common denominator among these names was weakness in the retail and energy sectors, which has been a recurring theme recently. Retail struggled with the disruptive evolution from the traditional brick-and-mortar channel to e-commerce. For energy, the price of oil declined significantly in the quarter, causing a commensurate drop in stocks in the industry.

In terms of acquisition activity, Kate Spade agreed to a merger with Coach during the quarter but at a price that disappointed investors, including ourselves. (We discuss this in more depth later in the letter.) The Fund benefited from a more attractive acquisition outcome in the quarter for Fund holding VWR, a distributor of laboratory equipment and supplies.

For the calendar six months, Oracle, Nestlé, Philip Morris, Bank of America and TE Connectivity contributed most while Foot Locker, Baker Hughes, National Oilwell Varco, Kate Spade and Arconic were the biggest detractors. For the nine months of the Fund's current fiscal year, Bank of America, Oracle, TE Connectivity, UnitedHealth and General Motors led the contributors' list, while Foot Locker, CVS Health, National Oilwell Varco, Arconic and HSN detracted most.

Balanced Fund/Target Date Fund?

Balanced funds—i.e., funds that mix different asset classes such as stocks and bonds—have been part of the investing landscape for scores of years. Historically, they were seen as the investing answer to investors seeking a mix of growth and income but with buffered volatility. Over the past few decades, the investment management industry has been creative in new product development, including in this area. Target date funds emerged in the 1990s as an alternative to balanced funds, particularly in retirement accounts. Target date funds remove the asset allocation decision from the investor. Instead, these funds automatically adjust their asset allocation over time, based on the investor's age or anticipated retirement date. Note, however, that this automation also takes the allocation decision away from the portfolio manager, since the fund mechanistically reallocates away from equities as time passes.

Although target date funds are conceptually appealing, in our opinion the market environment will determine their ability to meet the needs of their investors. In a normal environment, the "glide path"—or the transition from equities to bonds—can make sense. As investors near retirement, they want less risk, which fixed income securities typically provide. The problem

arises when fixed income's riskiness is above normal, as we believe it to be today. One measure of potential riskiness is duration, which measures how much interest rate changes will affect the price of a security. Higher durations imply greater interest rate sensitivity, which can mean that the risk of a loss is increased. Today, fixed income durations are very high across the entire spectrum of issues, a function of historically low interest rates. In the circumstance of someone who will be consuming their retirement account over time, the risk is that he or she will be selling supposedly safe fixed income assets at a loss should rates normalize to historic averages.

A very recent paper published by the University of Waterloo compares target date funds to basketball players who shoot the ball in an identical fashion, regardless of where they are positioned on the court. "The player is following a deterministic process, not focused on an end goal (sinking a basket)," the authors write. "In contrast, a player following an adaptive strategy will shoot at different angles and velocities, depending on where he is in relation to the basket, always keeping in mind that the goal is to sink the basket."¹⁰ Although the "adaptive strategy" that the authors elaborate differs from that which we employ in the Equity and Income Fund, the general concept is the same. We invest in the most attractively valued assets, depending on the environment, and by doing so, we attempt to buffer the risk of material loss of capital. We believe that this approach has stood the test of time. Perhaps time will prove that target date funds are also a valuable addition to the investing landscape, but for now we hope that investors understand their risks as well.

Transaction Activity

The Fund's overall asset allocation ended the quarter little changed from the previous report. During the quarter, we initiated new positions in CommScope Holding Company (COMM) and eliminated the Kate Spade holding after the merger agreement with Coach was announced. CommScope is a leading provider of infrastructure equipment for wired and wireless communications networks. Increasing requirements for capacity and speed across data, video and voice networks should drive low- to mid-single digit organic growth at the company. We believe the management team has shown themselves to be excellent operators with a history of strong revenue and earnings growth and a track record of successful merger integrations. The company is ahead of schedule in realizing synergies from its recent acquisition of Broadband Network Solutions (BNS) from TE Connectivity. CommScope businesses generate significant cash flow, and the company is rapidly paying down debt. Trading at a P/E in the low teens and at a discount to private market value, this high-quality company is selling at a very attractive price in our view.

As previously stated, Kate Spade agreed to a merger with Coach at an acquisition price that we found disappointing and below what we considered fair value. It may be that we were simply wrong in our assessment of the franchise's worth, but we think that the poor retail environment worked to degrade the sales process and produced a non-optimal outcome.

As always, we thank our shareholders for entrusting their assets to the Fund and welcome your questions and comments.

Why A Global Fund?

Investors today have literally thousands of options when considering where to place their long-term assets. Index funds, specialized exchange traded funds (ETFs) and mutual funds in many varieties all clamor for investors' attention. So, why do we think that a value-based, all-capitalization global fund is worthy of your consideration? Value investing is a discipline that has stood the test of time. Combining its virtues with the flexibility inherent in an all-cap global fund offers the potential to identify and exploit undervalued securities wherever they may be found, and that is our intention for Oakmark Global.

The Oakmark Global Fund's three-month return was 4.3%, which compares to the MSCI World Index¹¹ 4.0% return during the period and the Lipper Global Fund Index's¹² gain of 4.6%. For the first six months of 2017, the Fund gained 12.2%, which contrasts to 10.7% for the MSCI World Index and 11.9% for the Lipper Global Fund Index. For the Fund's fiscal year, which began October 1, 2016, the returns are 20.8% for the Fund, 12.7% for the MSCI World Index and 14.2% for the Lipper Global Fund Index. Since inception in 1999, the Fund has achieved a compound annual rate of return of 10.3%, which compares to 4.5% for the MSCI World Index and 5.3% for the Lipper Global Fund Index.

The U.S., the U.K. and Germany contributed most to the Fund's return in the quarter, while Australia, Mexico and Japan detracted from return. The five largest contributors to Fund return in the quarter were CNH Industrial (U.K.), Citigroup (U.S.), Lloyds Banking Group (U.K.), Allianz (Germany) and Alphabet (U.S.). The Fund holdings that detracted most were National Oilwell Varco (U.S.), Incitec Pivot (Australia), USG (U.S.), Toyota Motor (Japan) and Grupo Televisa (Mexico).

For the first six months of 2017, the U.S., the U.K. and Germany contributed most to investment return, while Japan was the only detractor. The leading contributors were CNH Industrial, Allianz, Oracle (U.S.), Lloyds Banking Group and Alphabet. The largest detractors were Toyota Motor, National Oilwell Varco, Arconic (U.S.), CarMax (U.S.) and Daiwa (Japan).

For the fiscal nine months, the U.S., the U.K. and Switzerland contributed most to return while Mexico was the only country that detracted. The equities that contributed most were CNH Industrial, Bank of America (U.S.), Citigroup, Allianz and Lloyds. The most significant detractors were Tenet Healthcare (U.S.), Toyota Motor, National Oilwell Varco, Arconic and Grupo Televisa.

Country Classification

In June, MSCI announced that it was adding mainland Chinese stocks to its emerging markets index. We would guess that many investors thought this had been done long ago—China is the world's second largest economy, after all. But certain processes take considerable time. MSCI's definitions focus on corporate governance, as well as market and institutional development, and they place less emphasis on economic factors. In any event, this has promoted considerable discussion and some activity as benchmark-sensitive investors prepare for this change.

Of course, we are not benchmark-oriented investors, so MSCI's actions do not inspire any action on our part. We focus on corporate governance and the domicile country rule of law when we consider whether to invest in a foreign security. We always wish to treat our investors' hard-earned money with the greatest respect, and to that end we attempt to invest only in markets that we believe will protect investors from capricious or nefarious actions.

Financial Times columnist John Authers recently wrote a piece describing what he called a "taxonomy that divides investment markets into nine different governance regimes."¹³ This is credited to JP Smith of the Ecstrat consultancy. We don't endorse all of Smith's distinctions or country placements, but this structure can be a useful template when evaluating different international investment alternatives.

For our purposes, Smith's first three categorizations are the most valuable. He defines "liberal" countries as those with transparent markets with separate ownership and control, and a domestic base of investors who prioritize returns. The second group he calls "co-ordinated" where corporate control lies with shareholders who own large blocks of stock. The third group he calls "network" where companies obtain most financing from other companies, banks or families within their network. The remaining six classifications go from "hierarchical" to "disrupted," and imply ever-decreasing degrees of non-domestic investor protections.

As we have written many times, investing with corporate managers who think and act as owners is a vital part of our investing discipline. And we attempt to invest with managers who treat their shareholders as their partners. As we travel down Smith's country categorization, it becomes ever more difficult to identify companies that meet our investing demands. Over time, countries can move from one category to another, and it is important for us to be attuned to such

developments. Columnist Authers writes that Smith's "sub-divisions are more useful than a sweeping division of the world into developed, emerging and 'frontier.'" Probably so, but for us the key consideration is whether the potential investment truly and fairly respects the Fund's clients. If we can answer that with a strong "yes," then its classification is fairly unimportant.

Portfolio Activity

We did not initiate any new purchases for the Fund in the quarter. Our one elimination was Samsung, the South Korean technology company. As Samsung's shares approached our sell target, we sold the name to increase our investment in more attractively priced issues. We note that Samsung's shares performed particularly well in our view given the unfortunate problem that developed with the company's Note 7 smartphone.

Our country weights moved very little in the quarter aside from our exit from South Korea. The Fund remains underweight the U.S. relative to the MSCI World Index, as it has for several years. Previously the stronger relative performance of U.S. equities meant that this weighting had detracted from the Fund's relative performance, but in 2017 this has reversed. As always, we do not invest with the benchmark in mind and instead go where we find the most attractive, undervalued equities. The U.K., Germany and Switzerland are the Fund's greatest overweights versus the Index.

We continued to believe some currencies are overvalued. As of quarter end, approximately 11% of the Swiss franc exposure was hedged. We no longer hedge the Fund's Australian dollar exposure because we believe the currency is near fair value.

At the beginning of this letter, we briefly described the case for all-cap global funds. In closing, we should state that we find this form of investing to be invigorating and energizing. Simply put, managing the Global Fund is fun! We thank you for giving us the opportunity to invest in this fashion. Please feel free to contact us with your questions or comments.

The Oakmark Global Select Fund returned 6.2% for the quarter ended June 30, 2017, outperforming the MSCI World Index's¹¹ 4.0% return. Most importantly, the Fund has returned an average of 8.8% per year since its inception in October 2006, outperforming the MSCI World Index's annualized gain of 5.3% over the same period.

CNH Industrial, a global agricultural and construction equipment manufacturer, was the top contributor for the quarter, returning 18%. The company delivered positive first quarter earnings, as both its revenue and earnings exceeded consensus estimates. The industrial business saw an improvement with its year-over-year earnings increasing 34%, driven primarily by a 77% improvement in the agriculture equipment segment. The industry has seen stabilization in global agricultural equipment markets and is beginning to see the early stages of restocking. Also during the quarter, S&P raised CNH's credit rating to investment grade, which should allow the company to improve its balance sheet efficiency and refinance its debt at lower rates.

GE, a global producer of industrial, household and medical goods, was the largest detractor for the quarter, declining 9%. Shares were weak due to the company's exposure to energy end markets (which was increased via its merger with Baker Hughes, a contrarian acquisition we believe will prove to be well timed). The stock was also hurt by an analyst downgrade during the quarter, which cited concerns that GE's cash flows were lagging behind the company's reported profits. In our view, this concern will prove to be irrelevant to the long-term investment case, as two of GE's longest cycle businesses (aviation and power) are in the midst of their largest new product launches ever, both of which require large investments in inventory and other working capital accounts that will reverse over time. In addition, GE has recently worked to reinvent its portfolio and possesses a renewed focus on achieving appropriate capital returns. As such, the company completely revamped its variable compensation plan for thousands of employees who are now paid on a number of factors that emphasize improving its return on invested capital. We believe such changes will lead to much better performance and that GE's long-term outlook, therefore, remains promising.

Geographically, 50% of the Fund's holdings were invested in U.S.-domiciled companies as of June 30, while approximately 50% were allocated to equities in Europe.

We continue to believe some currencies are overvalued. As of quarter end, approximately 10% of the Swiss franc exposure was hedged.

Both the Oakmark International and International Small Cap Funds performed well in our view in the second quarter of 2017. In fact, the strong performance across our strategies has continued from the post-Brexit rebound that began early in the third quarter of 2016. More importantly, our long-term positive track record remains intact. Please see the individual Fund letters for details.

The Wake of Brexit

A little more than one year ago, citizens of the U.K. voted to leave the European Union. Global equity markets strongly reacted to this decision as the pound sterling dropped and the yen, viewed as a "safe haven," strengthened. In addition, stocks dropped globally, especially in the European Union and the U.K. As the yen strengthened, share prices of Japanese stocks softened, especially of exporters, and European financials were particularly hard hit.

I have often written about the opportunities that arise when price movements vary greatly from changes in underlying intrinsic value. In fact, I wrote one year ago:

"During the first two days after the vote, the European stock index dropped just under 15%, with the European financials dropping even more. I would assert that, as often is the case, the underlying intrinsic value of the corresponding businesses did not change as drastically as the market price. In fact, this is usually the case as fearful traders and investors often sell in a knee-jerk reaction in response to any geopolitical disturbance. We believe that for real investors, it provides an opportunity. Our process is to first try to measure the true impact these events may have, if any, on the intrinsic value of the businesses we own and then to respond in a way that takes advantage of the market's short-term fears. Again I stress the point we often make: Volatility is opportunity!"

Despite the uncertainty caused by Brexit and a recent general election in the U.K., which resulted in a lost majority for the still-governing Conservative Party, the British economy is performing acceptably well with a 2% year-over-year growth rate. To be sure, economic challenges remain, but the weaker pound sterling has aided currency-sensitive sectors such as exporters and tourism. Meanwhile, despite consumer confidence softening, strong employment has indicated that the recession many predicted has not materialized.

We used this period to actively increase our exposure to those companies that were hardest hit and where we believed the change in price was not at all reflective of the changes in

underlying value. Because of this discipline, embodied in our philosophy and process, shareholders in both Oakmark International and International Small Cap have richly benefitted by earning year-over-year returns (dividends reinvested) of 40.0% and 31.6%, respectively. Though events like Brexit are often traumatic and very difficult to stomach, they can provide opportunity for those who are patient.

The Friedman Doctrine

Nobel Prize-winning economist Milton Friedman wrote the following on the topic of Corporate Social Responsibility: "There is one and only one social responsibility of business—to use its resources and engage in activities designed to increase its profits so long as it stays within the rules of the game, which is to say, engages in open and free competition without deception or fraud."¹⁴ You will frequently hear from Harris Associates' investment professionals that we want to invest with management teams "that think and act like owners." This is why, as a professional investor who is charged with looking after my shareholders' and clients' wealth and savings, I find it distressing when corporate boards and managements get distracted from their role of maximizing shareholder value.

A recent example of questionable corporate stewardship occurred when the Board of Directors of Akzo rejected multiple offers by PPG to purchase the company at a greater-than 50% premium and what appeared to be a generous valuation of the Akzo business. Unfortunately, Dutch corporate governance rules do not allow for the direct election of directors by shareholders, thereby insulating managements and boards from the consequences of pursuing actions that lead to value destruction.

Sadly, the Netherlands isn't the only example of countries that support polices that inhibit shareholder value creation. In Japan, for example, hostile takeovers are nearly impossible because corporate Japan often uses cross-shareholdings and other methods to "circle the wagons" around weak corporate characters, which prevents positive change. As a result, there has been a wave of value destruction throughout corporate Japan. In addition, outside groups, consulting firms and some non-profits have recently begun to exert pressure on corporate boards and managements to make decisions that reflect their own needs, values and causes, but often are to the detriment of shareholders and long-term value creation.

Clearly, we desire the companies in which we invest to be good corporate citizens. But this is different than succumbing to the wishes of those who often possess conflicting demands based on their pet causes. Often, those we expect to stand up to this

The Oakmark International Fund returned 6.2% for the quarter ended June 30, 2017, outperforming the MSCI World ex U.S. Index¹⁵, which returned 5.6% over the same period. Most importantly, the Fund has returned an average of 10.1% per year since its inception in September 1992, outperforming the MSCI World ex U.S. Index, which has averaged 6.1% per year over the same period.

Intesa Sanpaolo, an Italian retail and commercial bank, was the top contributor to performance for the quarter, returning 22%. Intesa reported good first quarter results that were in line with our expectations. In our view, costs remain well controlled, and asset quality continues to improve as non-performing loans decline. Shares of Intesa rose after the European Central Bank and Italian government announced plans to rescue two Italian banks, putting an end to months of concern that their failures could undermine confidence in the Italian banking system. As part of the deal, Intesa will acquire €26 billion of performing loans and €4 billion of high-risk performing loans from the two banks. While management has not been interested in acquisitions in the past, the assets and terms of this deal were attractive in our view. First, the asset quality of the €26 billion in performing loans is better on average than Intesa's current portfolio. In addition, Intesa will have the option to return the high-risk performing loans to the government if its asset quality deteriorates. Finally, Intesa paid merely a token price to acquire the portfolio of loans, while the Italian government agreed to contribute nearly €5 billion to maintain Intesa's high capital ratios and dividend payments. We believe that this transaction will create value for shareholders.

Honda, Japan's second-largest automaker, was the largest detractor from performance, declining 8% during our holding period. We've been a long-term shareholder of Honda, but we have grown increasingly frustrated with management's inability to explain continued margin weakness in the company's auto segment. Despite entering the sweet spot of the model cycle, margins remain weak. In addition, there have been multiple missteps by management at a time when North America, the company's main market, has been booming. Although Honda is still trading at a discount to its intrinsic value, we have lost faith in management's ability to create long-term shareholder value and sold our position.

During the quarter, we also sold our position in Check Point Software. We purchased one new name during the quarter, Axis Bank, which is the third-largest private sector bank in India. It shows strong prospects due to robust economic growth, increasing loan penetration and market share gains.

Geographically, we ended the quarter with 79% of our holdings in the U.K. and Europe, 6% in Japan and 3% in Australia. The remaining positions are in China, Indonesia, Mexico, the U.S., India, Hong Kong, South Korea and Taiwan.

The Oakmark International Small Cap Fund returned 9.1% for the quarter ended June 30, 2017, outperforming the MSCI World ex U.S. Small Cap Index¹⁸, which returned 7.3% for the same period. Since the Fund's inception in November 1995, it has returned an average of 9.9% per year.

The top-performing stock for the quarter was Melco International Development, a Hong Kong-based holding company that controls Melco Resorts & Entertainment in addition to other casino gaming and tourism assets. During the quarter, the company's stock price rose after Melco Resorts & Entertainment announced that its first quarter revenues surpassed market estimates by roughly 8% and that its earnings far outpaced market forecasts by about 19%. These strong results reflected the recovery in Macau's gross gaming revenue, which has increased for several consecutive months. Melco Resorts has impressive plans to continue to grow its business in Macau, which chairman and CEO Lawrence Ho discussed with us in a May meeting. We came away confident that Melco Resorts' leadership team is steering the company in the right direction and that these efforts will benefit the subsidiary's shareholders as well as the shareholders of Melco International Development.

The largest detractor to Fund performance for the quarter was Canada-based Element Fleet Management. Element is the largest provider of fleet management services in North America—more than twice the size of the second-largest player. A number of factors hurt the stock's performance during the quarter. The most significant issue was a joint venture between Element and financially troubled truckload operator Celadon. We share the market's concern that the joint venture could result in asset write-downs, but we remain comfortable that Element has the balance sheet strength to meet any capital requirement associated with its involvement. Despite some near-term challenges, we continue to find Element an attractive medium- to long-term investment. Element's scale, coupled with the platform nature of the fleet management business, should enable the company to generate strong over-the-cycle returns, which we expect to become increasingly evident in the coming quarters.

Hengdeli Holdings, based in Hong Kong, was the second-largest detractor to Fund performance for the quarter as minority shareholders approved the sale of the company's mainland China retail operations to Hengdeli's founder, Mr. Zhang Yuping, at book value—a staggering 50% discount on our estimate of intrinsic value. Hong Kong's listing rules provide protection to minority shareholders as Mr. Zhang was prohibited from voting on the transaction. Despite this, more than 70% of shareholders voted in favor of it. In addition, the independent members of the board of directors failed to look out for the best interests of shareholders by recommending approval of the transaction and publishing a delayed and, what we consider, highly misleading circular. The board's apparent lack of inde-

pendence is frustrating, but the ultimate responsibility for the vote rests with the minority shareholders, who clearly did not complete the necessary due diligence to properly assess the transaction. The market reacted quickly to this destructive deal, and Hengdeli's share price dropped approximately 40% during the quarter. We are highly disappointed with the outcome of the vote and believe Hengdeli's remaining operations in Hong Kong offer little value. We are not confident that the management team can add value via mergers and acquisitions, given what we believe is its very poor historical track record. As a result, you will notice we have trimmed our position.

We initiated positions in two new holdings this quarter, Sabanci Holding and Sarana Menara Nusantara. Based in Turkey, Sabanci Holding is a conglomerate with a focus in the industrial and financial sectors. Approximately one-half of the asset value of Sabanci comes from its stake in Akbank, the third-largest bank in Turkey. The company is also active in a number of other sectors, including cement, retail and electricity. Sarana Menara Nusantara is an Indonesian investment company that owns and operates telecommunication towers for wireless operators through its subsidiary Profesional Telekomunikasi Indonesia ("Protelindo"). With more than 14,500 towers, Protelindo is the largest independent owner and operator of towers in Indonesia. Finally, we eliminated our position in Melrose Industries (U.K.) during the quarter.

Geographically, we ended the quarter with 20% of our holdings in Asia, 62% in Europe and the U.K., and 10% in Australasia. The remaining positions are 4% in North America (Canada and the U.S.) and 3% in Latin America (Brazil and Mexico).

As of the quarter end, the Swiss franc hedge was 10% and we closed the Australian dollar hedge as we believe the currency approached fair value.

Thank you for your continued confidence and support.

Reporting to Shareholders. The Funds reduce the number of duplicate prospectuses, annual and semi-annual reports your household receives by sending only one copy of each to those addresses shared by two or more accounts. Call the Funds at 1-800-OAKMARK to request individual copies of these documents. The Funds will begin sending individual copies thirty days after receiving your request.

Before investing in any Oakmark Fund, you should carefully consider the Fund's investment objectives, risks, management fees and other expenses. This and other important information is contained in the Funds' prospectus and a Fund's summary prospectus. Please read the prospectus and summary prospectus carefully before investing. For more information, please visit Oakmark.com or call 1-800-OAKMARK (625-6275).

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 Fund: 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 Fund's 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.
