Dear Fellow Shareholders,

Markets were mostly positive during the fourth calendar quarter for The Oakmark Funds. International markets posted strong gains, as did our international and global Funds. While U.S. markets overall were weak, the returns on our U.S.-focused Funds matched or beat their benchmarks.

The Equity and Income Fund slightly outperformed its benchmark during the quarter, but it continues to lag for the one- and three-year annualized periods. Our portfolio managers discuss their thoughts on the quarter and the opportunities ahead in their shareholder letters.

Reviewing our performance reminds us of the importance of sticking with a long-term asset allocation decision. Investors who maintained or increased their allocations to equities in 2012 were rewarded, while those who abandoned equity strategies have experienced the opportunity cost of missing these rising markets. At Oakmark, our philosophy focuses on investing for the long term. It takes discipline and, at times, fortitude to consistently follow this course, but doing so has rewarded our shareholders for more than two decades. We encourage you to stay on course as you look forward to 2013.

Oakmark Chairman Wilner Retires

Dr. Gary Wilner retired as Chairman of The Oakmark Funds effective December 31, 2012. During his 19 years as a Trustee, including eight as Chairman, Dr. Wilner provided thoughtful guidance and demonstrated excellent stewardship of shareholder assets through eventful times. All of the trustees and officers that serve The Oakmark Funds appreciate his counsel. He has exemplified the level of dedication required to uphold the trust and expectations of those who follow and invest in our esteemed fund family. He was succeeded on January 1 by Allan Reich, who enjoys a similar length of tenure and experience as an Oakmark Trustee,

and who has earned the great respect of his peers. We thank Gary for his excellent service over these years, and look forward to working with Allan in his new capacity.

A New www.Oakmark.com

We have rebuilt our Oakmark.com website to provide easier access to information about your Funds. We plan to release this new site at the end of January, and we look forward to your feedback on how well it works for you. We have updated the design to place content at your fingertips, both in summary fashion and with deeper drills into portfolio details and our investment philosophy. The website should be a more effective venue for valuable communications about your funds and Harris Associates. Further, it simplifies navigation among the myriad literature and forms that assist in the management of your accounts. While we have made significant changes in the new Oakmark.com, your account access will remain in its customary location on the home page and the secure login process will not change.

Welcome to new Co-Managers

Harris Associates has announced that Tony Coniaris and Win Murray will join Bill Nygren as co-managers of the Oakmark Select Fund at the end of January. Both are proven research analysts with many years of experience at Harris, and have worked closely with Bill supporting the portfolio management function for some time now.

Clyde McGregor will continue to work with his internal advisory groups for the present time. They have made significant contributions to his evaluation of both the fixed-income and equity segments of the portfolio.

Personal Investments in the Funds

At Oakmark, we have found that significant management share ownership is an important attribute of successful companies. When a management team has a meaningful stake invested along with their company shareholders, the foundation for good, long-term stewardship is reinforced. We believe this is true for the companies that we invest in, as well as for the mutual funds that we manage. Significant ownership of Fund shares by all levels of employees at Harris Associates demonstrates our confidence in our investment process and our commitment to managing your funds with integrity.

We are proud to report that, as of December 31, 2012, the value of Oakmark Funds owned by the employees of Harris Associates, our families, the Funds' officers and our trustees was more than $335 million. Sharing this information with you annually attests to our conviction, both professionally and personally, that our Funds remain attractive investments for the future.

Thank you for your continued investment and confidence in the Oakmark Funds. We welcome your comments and questions.

Kristi L. Rowsell

The Oakmark Fund increased 3% for the past quarter, compared to an unchanged S&P 500 Index. For the full year of 2012, Oakmark Fund increased 21%, compared to 16% for the S&P 500 Index. We are very pleased with those results and hope you are, too.

The quarter's best performer, and because of that performance, now our largest position, was Bank of America, up 32%. Next best was Delphi Automotive, up 23%. Throughout the year, we have believed that the most undervalued stocks were those that had some exposure to economic cyclicality. We don't ever wake up in the morning saying, "Boy, I wish our portfolio had more cyclic risk." However, when investors price cyclic businesses at very large discounts to stable businesses, we are more than happy to be bargain purchasers. The businesses of Bank of America and Delphi are expected to perform better in strong economies. Both were selling at what we considered to be bargain prices relative to our estimate of their "normal" earnings. Despite the significant increases in their stock prices, both continue to sell at what we consider to be attractive valuations.

Our worst performer in the quarter was Apple, down 20%. Last quarter, I explained how our holdings in Apple actually hurt our relative performance, even though the stock had produced outstanding returns. Because our Apple weighting was only half that of the S&P 500 Index's, Apple contributed more to the index than to our portfolio. The reverse was true this quarter. Apple performed poorly, but because our weighting was less than the S&P 500 Index's, Apple actually helped our relative performance. Our weighting in Apple is based on our assessment of its attractiveness, not its market cap. We believe Apple is priced very cheap relative to its current level of earnings. If we were confident that its current earnings were sustainable and that its management would distribute those earnings to shareholders via dividends or share repurchases, we would increase our weighting.

We eliminated two holdings during the quarter, eBay and Time Warner. Both were very successful holdings for the Fund and were sold because their stock prices appreciated to levels that we believed were appropriate. We added one position during the quarter, Halliburton.

Halliburton (HAL-34)

Halliburton is the world's second-largest oil service contractor. It has a high and growing market share in most of its business lines, and its markets are growing. In 2011, the stock peaked at $58. Its price has fallen due to concerns about a short-term spike in raw materials costs and slower growth in North American pressure pumping, an important market for Halliburton. The shale drilling boom in North America has been especially good for providers of pressure pumping services, a market Halliburton has dominated. The recent slowdown in pressure pumping growth was caused by energy producers

The Oakmark Select Fund increased 5% during the quarter, while the S&P 500 Index¹ was unchanged. For all of calendar 2012, The Oakmark Select Fund returned 22%, compared to 16% for the S&P 500 Index. The Fund's absolute and relative returns are both well above historical averages. Though we are very pleased with this performance—and hope you are, too—we also want to remind you that we don't expect to perform this well in most quarters or years.

As we've said throughout the year, we believe investors are still paying a larger premium than they should for low-risk securities, and that we are finding better opportunities in companies with more economic sensitivity. Our exposure to financials and cyclicals contributed strongly to the quarter's results. Our best performer was Bank of America, up 32%. A few short years ago, Bank of America's ability to even survive was a legitimate concern. Today, it has emerged as arguably the financially strongest multinational bank. Yet, the stock still trades at a sharp discount to its book value and a low P/E on expected 2014 earnings. Our second-best performer was global auto parts supplier TRW Automotive, up 23%. Many investors have been concerned that demand for auto parts would fall if the economy turned down again. However, we believe that investors are just starting to understand the importance of emerging markets for the automotive industry. Long term, that growth is likely to overwhelm the cyclical ups and downs of Europe and the United States.

Our worst performer for the quarter was Newfield Exploration, down 15%. It was our only double-digit decliner. When a portfolio has two stocks up over 20% and only one down more than 10%, it will usually be a pretty good quarter. Though we are disappointed with Newfield's stock performance, we are pleased with management's decision to decrease spending on natural gas reserve development and instead spend that money on its oil properties. We believe Newfield sells at a very large discount to the field-by-field asset value of its properties.

An important change you'll notice in the portfolio is that our largest holding is now TRW Automotive, instead of Discovery Communications. Discovery had another very good year, up 55%. Though its business is performing well and we believe the stock continues to be somewhat undervalued, we sold some of our shares because we no longer believe its undervaluation is enough to warrant being our largest holding.

During the quarter, we eliminated our holding of BMC Software. BMC ended its strategic review with the decision to remain an independent company. We had believed BMC would be worth much more to a larger software company than as a stand-alone. The lack of a compelling offer during the strategic review forced us to conclude we were probably wrong. Though the price of BMC shares rose slightly during the time that we owned it, we concluded that its purchase was a mistake.

Kennametal replaced BMC in the portfolio. It is a classic mid-sized industrial business that appears to be benefiting from management improvement. Selling at less than 9 times our estimate of 2014 earnings plus amortization, we believe investors have not yet priced in that improvement.

On a more personal note, it felt odd last quarter seeing only my picture at the top of this report. Since March 2000, my picture had been side-by-side with my co-manager, Henry Berghoef. As previously reported, Henry retired last year, and having just seen him at our company holiday party, I can report that he is thriving in his new role. I always said it would be tough for any one person to replace Henry, but I believe that goal will be accomplished. I am pleased to report that when our prospectus is updated at the end of January, we will be naming not one, but two new co-managers: Tony Coniaris and Win Murray.

Why two? Because two exceptional candidates were available, and I saw no reason to exclude either one of them. Tony joined us in 1999 as a research assistant, a position that normally is a "two years and out" position. Our general preference is to let young analysts gain their experience elsewhere, and then we'll consider hiring them. But we didn't want to risk Tony not coming back. So we kept him on as a junior analyst and then promoted him to analyst. Meanwhile, Win joined us as an experienced analyst in 2003. Both Tony and Win were named partners in 2008, and Win was subsequently named our Director of U.S. Research. I have worked very closely with both of them for many years and am confident that they have not only the right skills to work on this portfolio, but as important, the right personalities.

Thank you for your continued confidence in our Fund, and best wishes for a healthy, prosperous 2013.

Quarter Review

U.S. equity markets followed up a strong September quarter with a choppy and unproductive December period. Fixed-income returns were modest as well. During the past quarter, the Equity and Income Fund earned 1%, roughly equivalent to the return for the Lipper Balanced Fund Index⁸, the Fund's performance benchmark. For the calendar year, the Fund returned 9% versus the Lipper index's 12%. Since the Fund's inception in 1995, the annualized compound rate of return is 11% while the corresponding return for the Lipper index is 7%.

The stocks with the greatest return contribution in the quarter were Rockwell Automation, Flowserve, Varian Medical Systems, Dover and Lear. The largest detractors were Devon Energy, Apache, Baker Hughes, EnCana and Philip Morris International. All of the detractors except Philip Morris are in the energy industry, which continues to suffer from the oversupply of natural gas. Detractors from return for the calendar year were Walter Energy, Devon Energy, Staples, Apache and Republic Services (sold). The largest 12-month contributors to portfolio return were Diageo, Flowserve, TJX (sold), MasterCard and Scripps Networks Interactive.

Although comfortably profitable for investors, calendar 2012 was relatively disappointing for the Fund. A variety of factors contributed to this outcome. Perhaps foremost was our belief that income had become overpriced, whether in bonds or higher-yielding equities. Financial repression has continued much longer than we thought possible, and this has, in our opinion, encouraged investors to overpay for income in every security type. Also important was our failure to foresee that exploration and production company stocks would become mere proxies for the price movements of natural gas, despite their attractive valuations. Finally, the Fund began calendar 2012 with little exposure to financial service stocks, a group that performed strongly. On the positive side, the Fund's consumer and industrial holdings provided favorable relative results.

Going forward, we are optimistic about the Fund's holdings. We believe our equities remain attractively priced (especially relative to bonds), and we continue to find promising investment opportunities. The Fund's 74% allocation to equities expresses this effort. Although the desultory interest rate environment tempers our interest in bonds, we have found occasional fixed-income opportunities to put money to work on our terms. As always, we look for value wherever we may find it, and believe that our current portfolio fully reflects that effort.

In the middle of December, the Fund experienced a curiosity: Three holdings announced significant acquisitions, and yet their share prices all went up. Typically, the acquirer in a deal experiences share price erosion as investors fret about the dilution of the company's previous attributes and the risk of overpayment. In these three instances, however, the market quickly

agreed with the managements of Arris Group, Crane and Mohawk Industries that their proposed purchases would help grow their company's per-share value. We will continue to study these transactions, but we find the market's reaction to be intriguing.

Transaction Activity

The Fund initiated five new equity holdings during the quarter and eliminated three. This increases the number of equities to 54, greater than is typical for the Fund, but consistent with the Fund's equity allocation being at its highest level ever. The Fund eliminated its holdings in Boston Scientific, VCA Antech and TJX. Boston Scientific continues to struggle with evolving standards for cardiovascular treatment, and the steep drop in the use of coronary stents has limited the company's growth prospects. VCA Antech, the largest chain operator of animal hospitals, has also strained to grow its per-share value as it suffers market share losses. In contrast, TJX contributed significantly to Fund returns, but we sold it simply because we believed it was no longer substantially undervalued. I laud and thank CEO Carol Meyrowitz and her team for their outstanding success in the always competitive retailing industry.

Taking our recent purchases in alphabetical order, this quarter we initiated a position in Bank of America—our first investment in the banking industry in over six years. Throughout that time period, I have felt that investments in this industry were not suitable for the Equity and Income Fund, given the Fund's position as the most risk-averse in the Oakmark family. Bank investment has been fraught with many hard-to-quantify risks, including opaque financial reporting, exposure to low-quality mortgages and the overall housing market, negatively evolving regulatory rules, substantial litigation and the industry's high degree of financial leverage, which amplifies the impact of all risks. But with each passing year since the nadir of the financial crisis, the industry has made progress addressing these issues. Regulators and auditors are scrutinizing banks' books with newfound vigor, bad mortgage balances have declined, the housing market is more stable, the broad strokes of many important regulatory rules have been established, considerable litigation reserves have been built and leverage has diminished. Over the past few quarters in particular, these issues have resolved such that bank stocks can once again compete for space in the Fund. Bank of America stands out as having the most compelling prospective return. For years, it was the poster child for all that was troubling about banks. But like the industry as a whole, Bank of America has made tremendous progress simplifying and "de-risking" its business. For instance, in just the past few quarters, it has gone from being one of the worst capitalized big banks to the best. (For perspective, the company's tangible common equity ratio is 64% higher than it was in 2006, which was before the crisis.) Although investors have started to reward the company for its progress and brought the stock up from its lows,

it is still being valued at a sizable discount to its peers. The discount derives both from stale perceptions of the company's relative risk profile and its relatively depressed near-term earnings. We expect this discount to close with time, as investors re-evaluate the "new" Bank of America and its profitability catches up.

Although the Bank of America purchase involves an industry that has not recently been in the Fund, the rest of the new purchases are more in the Fund's mainstream. BorgWarner is an auto parts manufacturer with unusually fast growth prospects. The company helps original equipment manufacturers cope with the ever-increasing requirements for improved fuel consumption. Crane is a mid-cap conglomerate with operations concentrating in flow control and aerospace. Kaydon, the smallest company of the five new holdings, is a well-managed niche manufacturer of bearings, filters and similar products. The stock also sports an attractive dividend yield. The fifth purchase was Principal Financial Group. Although Principal started its life as an insurer and the stock market values it as such, the majority of its earnings now come from higher return and lower risk asset management and administration services. These businesses produce ample cash flow that allows Principal to repurchase shares (its share count is down 8% over the past two years) and make attractive "bolt-on" acquisitions, all while paying a healthy dividend. As Principal's earnings mix continues to tilt toward asset management, we believe it will be rewarded with an earnings multiple similar to that of its asset manager peers, which trade at healthy premiums to insurers.

How Could Today's Bond Prices Actually Make Sense?

Readers of these letters (and those of many other commentators) have endured numerous rants against the prevailing low interest rates. We value investors argue that fixed-income investments are risky and artificially overpriced because of government intervention in the bond market. And yet, individual investors have continued to shift assets from equity funds to fixed-income funds, apparently ignoring the double-digit gains stocks realized in 2012. When we find ourselves out of phase with market trends, we seek divergent points of view that may help us understand the alternative thinking. Professor Robert J. Gordon of Northwestern University has provided such an analysis in a National Bureau of Economic Research paper published in August.

After the U.S. re-emerged from the 2008 financial crisis, economic growth did not follow the typical economic recovery pattern. Growth remained erratic and weak, and unemployment continued at dispiriting levels. Many investors began to worry that the U.S. was emulating Japan's experience. Japan's economy and stock market peaked more than 20 years ago. Since then, economic growth there has been modest, and interest rates on Japanese Government Bonds have been stuck at minimal levels. We have argued that the Japan experience is unique and that the U.S. has many characteristics (e.g., size, diversity, population growth, net immigration, natural resources) that militate against such an outcome.

Professor Gordon, however, presents a different thesis that could explain secular sluggish U.S. economic growth and concomitant low interest rates. He argues that, in contrast to the idea that economic growth is a continuous process that will persist forever, growth is actually associated with specific industrial revolutions, the most recent of which (computers, the internet, mobile phones) stopped being revolutionary in the

last decade. And, he argues, even were rapid innovation to continue, economic headwinds, such as demography, education, inequality, globalization, environment and accumulated debt, will inhibit future growth. Clearly, this is not a happy alternative thesis.

As value investors, it is not necessary that we have a definitive point of view regarding Professor Gordon's theories. Rather, we focus on today's security prices and attempt to determine their true worth. We believe that bonds are priced in alignment with Professor Gordon's proposition that long-term growth will be anemic. Our conservative positioning relative to fixed-income duration means that the Fund will benefit should interest rates increase, whether that happens as a result of economic growth or inflation. One of our founding partners, who had Russian heritage, often remarked that "the Czar always inflates the currency." In our opinion, monetary authorities the world over are working overtime to produce that outcome. In the meantime, the opportunity cost of our defensive fixed-income positioning is small since rates are so low.

In closing, I wish to thank the members of the Fund Advisory Groups who worked with me in 2012. Special thanks go to Matthew Logan for his assistance with this letter. And as always, I thank my fellow shareholders for investing in the Equity and Income Fund.

Quarter Review

With only a few exceptions, the September quarter's broad strength in equity markets carried over to the December quarter. The United States was the most important of those exceptions, however, as investors reacted to the national election and the approach of the "fiscal cliff." The Oakmark Global Fund gained 10% in the quarter, while the MSCI World Index¹⁰ returned 2%, and the Lipper Global Fund Index¹¹ returned 4%. The Fund's return for the calendar year was 20%. That contrasts to the 16% return for the MSCI World Index and the Lipper Global Fund Index's return of 16%. As always, we are most pleased to report the Fund's 10% compound annualized rate of return since inception, which compares to 3% for the MSCI World Index and 4% for the Lipper Global Fund Index for the same period.

The countries that contributed most to the Fund's quarterly return were the U.S., Japan and Switzerland. Although the broad U.S. market was weak, the Fund's comparatively concentrated portfolio of American holdings performed well. For the second consecutive quarter, the Fund did not have any countries that detracted from return. The five largest contributors to Fund return in the quarter were Daiwa Securities Group (Japan), Tenet Healthcare (U.S.), Canon (Japan), Toyota Motor (Japan) and Equifax (U.S.). The Fund holdings that detracted most were Square Enix Holdings (Japan), Intel (U.S.), Devon Energy (U.S.), Lab Corp of America (U.S.) and Apache (U.S.).

For the calendar year, the countries with the highest allocations—the U.S., Japan and Switzerland—were also the largest return contributors. Of course, this makes perfect sense in what has ended up as a strong year in most of the world. Again, given that 2012 ended so strong, no country detracted from the year's return. Daiwa, Snap-on (U.S.), Discovery Communications (U.S.), Oracle (U.S.) and Equifax were the leading contributors. Square Enix, Rohm (Japan), Health Net (U.S.), Intel and Apache detracted most from the 12-month return.

Japan

It was an eventful quarter in Japan. The election of a new prime minister Shinzo Abe, energized the market with anticipation of macro reform. Both the Nikkei 225¹² and the TOPIX¹³ indexes rose 6%, respectively, for the quarter. Mr. Abe is focused on invigorating the economy and counteracting decades-long deflation by implementing aggressive quantitative easing programs and formalizing a 2-3% inflation target. He believes these significant measures are necessary to spur an increase in capital investment and avoid further negative economic growth. In response to Abe being elected, the value of the yen has already begun to weaken. Abe only took office in late December, so it's premature to say that he will be the one to finally lead Japan to nominal GDP growth. His initial goals are encouraging, but Japan still needs to address micro reforms in order to encourage consolidation, create new businesses,

improve transparency, establish better corporate governance and reduce bureaucracy.

It is important to stress that our investing approach is based on fundamental, bottom-up research, focusing on businesses and not macro trends. Having said that, the weaker yen has benefited some of our export-oriented holdings, such as Canon (+23%), Toyota (+19%) and Omron (+23%). In addition, the strong Japanese equity market boosted Daiwa (+44%), the Fund's top performer for the quarter. Not all of our Japanese holdings enjoyed such positive performance. Square Enix (-17%) was the Fund's worst performer for the quarter. The company revised down its full-year numbers due to worse-than-expected game launches. The gaming industry has always been driven by "hits," and "misses" are unfortunately a part of the business, too. More broadly, the industry is cyclically weak because we are in between console launches from Microsoft, Sony and Nintendo. In addition, the move to more social and mobile gaming is disrupting the industry. We continue to believe that companies with strong content, like Square Enix, will survive and excel regardless of the hardware used to play games.

Lumpiness

The December quarter proved to be quite favorable to the Fund, and its managers would like nothing more than to bask in the quarter's glow. Many shareholders, however, make sure that we do not fall prey to that temptation. Shareholders often ask us why we cannot construct a less volatile, more consistent return stream. Would that we could. Of course, long-time readers of reports from Oakmark managers have learned to expect this lumpiness in the pattern of returns, and they understand it is an inevitable outcome of our style of value investing. As value investors, we attempt to take advantage of the human tendency to oscillate between ebullience and pessimism. This spectrum can be seen in individual securities or in the market for an entire country (e.g., the U.S. after 9/11 or Japan after the tsunami). But the market's ability to bring price and value together is inconsistent and erratic, and this dictates that the Fund's return stream will experience volatility.

Although calendar 2012 proved to be a successful period for the Fund, the year was far from smooth. The quarterly return sequence was +16%, -8%, +2% and +10%. This pattern is more erratic than some years, but it is far from abnormal. It is also common for the Fund's short-term returns to differ from those of its benchmarks because of its concentration and value orientation.

For the past five years, individual investors have relentlessly liquidated holdings of equity mutual funds. Some of this liquidation activity may be a natural outcome of the aging of the large Baby Boom generation, the oldest members of which turn 67 this week. But we suspect that much of the move away from equities stems from the fear of volatility, particularly given investors' experiences in 2008. In our opinion, investors are

better served by focusing on the very long term, at least five years. One calendar quarter is too short a time period to be anything but a curiosity, and although a year has astronomical relevance, it also is not long enough for productive investing. As noted in the first paragraph, Oakmark Global has earned a 10% compound rate of return over its 13 years, but this has included many shorter term losses. Nevertheless, investors who have been patient from inception have seen the value of their shares triple (pre-tax). We thank our Fund investors for their loyalty and persistence, especially in a lumpy year like 2012.

Portfolio Activity

Unusually for the Fund, we neither initiated any new holdings nor did we eliminate any existing positions in the quarter, meaning that changes in country allocations resulted only from rebalancing and price movements. The Fund's largest overweight countries, when compared to the MSCI World Index, continue to be Japan, Switzerland, Germany, Spain and Italy. Because the Fund is focused and value-oriented, it does not hold positions in many countries that are part of the MSCI World Index. As we wrote last quarter, the largest underweights include the U.K., the U.S. and Canada. At 46%, the U.S. is by far the Fund's largest country allocation, but this is still 6% below the benchmark. Until the December quarter, U.S. equities had outperformed most international markets, and we have taken advantage of this inequality to rebalance into more attractively valued international equities. As managers and investors in the Fund, we have no incentive other than to have the Fund own the most attractive equity securities, wherever they may be found.

Currency Hedges

Even after an 11% depreciation of the yen versus the U.S. dollar during the quarter, we still see it as overvalued. Abe and many other business leaders also believe the yen should continue to weaken—anticipating that an exchange rate around 90 yen to the U.S. dollar is a reasonable level for Japanese exporters to make acceptable profits. As such, we continue to have 53% of our exposure hedged. We also continue to believe that the U.S. dollar is undervalued relative to other global currencies, so approximately 56% of the Fund's Australian dollar and 34% of the Swiss franc exposures were hedged.

The Oakmark Global Select Fund returned 11% for the quarter ended December 31, 2012, outperforming the MSCI World Index's¹⁰ 2% return. For the calendar year, the Fund was up 24%, while the MSCI World Index returned 16%. The Fund has returned an average of 6% per year since its inception in October 2006, outperforming the MSCI World Index's annualized gain of 2% over the same period.

Daiwa Securities Group, Japan's second-largest broker, was the largest contributor to performance for the quarter and the year, returning 44% and 79% respectively. Daiwa has been mentioned as a detractor in previous letters because it had been hurt by numerous factors, including a particularly weak Japanese stock market and decreased equity- and capital-market activity in Japan. However, many recent positive events in Japan have caused the equity market to rally. A new prime minister was elected and has indicated his intention to press for macroeconomic reform. One of his goals is to increase inflation targets to try to reverse two decades of deflation. The mere discussion of such reforms caused the market to rally and the Japanese yen to weaken to levels not seen in more than two years. Further improvements in economic growth should have a positive impact on Daiwa. Management's focus on retail and asset management may also be a game changer. Daiwa spent three years researching this venture and came up with an Internet bank that gives customers access to Daiwa branches. The company aims to attract customers by offering higher rates and a better platform than competitors in the hope that customers will move more of their deposits to investment products. Daiwa's balance sheet is well-capitalized, and we continue to believe it is a powerful franchise.

Intel, which holds about 80% of the market for microprocessors that go into personal computers and computer servers, was the top detractor for the quarter, returning -8%. Intel's stock has suffered recently due to a very challenging economic environment. In addition, news that Apple engineers are exploring ways to switch Mac processors from Intel to self-developed ARM-based chips also weighed on the company's stock price. We have heard similar reports in the past and believe that technology companies such as Apple are always looking for ways to streamline and consolidate their in-house designs. While we think that this transition may eventually occur, we believe that a change of this magnitude is still years away. In the meantime, Intel remains an innovation leader and, in our view, the company's design and manufacturing technology has never been better. As an example, Intel just announced its new Clover Trail processor for Windows 8 tablets (with specific product announcements from several major manufacturers including Dell, Hewlett-Packard, Samsung and Acer). We believe Intel has more than enough inherent strength to withstand the current industry product transitions.

Dell, a U.S.-based computer and electronics manufacturer, was the top detractor from performance for the calendar year, falling 30%. The company's share price has fallen in response to decreasing revenue growth in its PC business. PC revenue declined due to weak industry trends and a shift in demand to lower-priced PCs that Dell's Asian competitors produce at lower cost. However, Dell's non-PC businesses are performing well. We think this is significant because the company's non-PC businesses comprise over half of Dell's earnings and the overwhelming majority of its value. We continue to believe that Dell is attractively priced because investors pay too much attention to the declining PC business, which is the smaller piece of Dell's value.

During the quarter, we sold our position in Comcast and initiated a position in American International Group (AIG). AIG is one of the world's largest insurance firms, serving commercial, institutional and individual customers in more than 130 countries. While AIG is still associated with the 2007-08 financial crisis (having required over $180 billion in government support), it has made remarkable progress under the leadership of CEO Robert Benmosche. The government loans have been completely repaid and, in December 2012, the government sold its last remaining shares. Additionally, the company has been selling its riskiest and non-core businesses at attractive prices. Moreover, the company has been focusing on its underperforming but strategically well-positioned property-casualty and life insurance segments and retirement operations. Management has also been repurchasing stock at a large discount to book value. The streamlined company structure has made it easier to estimate the company's value, which like any insurer, we base on current and future earnings outlook, the quality of its reserves and how the capital will be invested. We believe that this renewed balance-sheet strength, along with its global presence, strong brand name and large discount to book value, make AIG an attractive investment.

Geographically, 42% of the Fund's holdings were invested in U.S.-domiciled companies as of December 31, while approximately 35% were allocated to equities in Europe and 18% to Japan. The remaining assets were invested in Canadian stocks.

Due to the U.S. dollar's weakness relative to other global currencies, we currently hedge two underlying foreign currencies, the Japanese yen and the Swiss franc. Due to the weakening yen, we decreased our hedge from 42% to 24% of the underlying currency during the quarter.

We would like to thank our shareholders for continuing to support us and our value-investing philosophy. As we ring in a new year, we believe we have built a portfolio of high-quality companies that will provide our shareholders with attractive returns over the long term.

Happy New Year!

The Oakmark International Fund returned 14% for the quarter ended December 31, 2012, outperforming the MSCI World ex U.S. Index¹⁴, which returned 6% over the same period. The Fund's calendar-year performance was strong in absolute and relative terms, returning 29% versus the MSCI World ex U.S. Index's return of 16%. Most importantly, the Fund has returned an average of 10% per year since its inception in September 1992, outperforming the MSCI World ex U.S. Index, which has averaged 6% per year over the same period.

Daiwa Securities Group, Japan's second-largest broker, was the largest contributor to performance for the quarter, returning 44%. Daiwa has been mentioned as a detractor in previous letters because it had been hurt by numerous factors, including a particularly weak Japanese stock market and decreased equity- and capital-market activity in Japan. However, many recent positive events in Japan have caused the equity market to rally. A new prime minister was elected and has indicated his intention to press for macroeconomic reform. One of his goals is to increase inflation targets to try to reverse two decades of deflation. The mere discussion of such reforms caused the market to rally and the Japanese yen to weaken to levels not seen in more than two years. Further improvements in economic growth should have a positive impact on Daiwa. Management's focus on retail and asset management may also be a game changer. Daiwa spent three years researching this venture and came up with an Internet bank that gives customers access to Daiwa branches. The company aims to attract customers by offering higher rates and a better platform than competitors in the hope that customers will move more of their deposits to investment products. Daiwa's balance sheet is well-capitalized, and we continue to believe it is a powerful franchise.

Lloyds Banking Group, the dominant retail bank in the U.K., was the top contributor to performance for the year, returning 94%. As discussed in last quarter's letter, we initiated our Lloyds position in December 2011, when uncertainty about macroeconomic conditions and Lloyds's management succession caused shares to fall. Prices have since rebounded. The new CEO, Antonio Osorio, is more focused on cost efficiency and risk controls than previous leaders, and he is intent on disposing of non-core assets. The HBOS integration continues. We expect credit costs to come down as Lloyds works through its HBOS book. We continue to believe that this integration affords significant opportunities for cost improvements, although it will be some time before they are realized. We believe Lloyd's strong deposit franchise is being significantly undervalued by the market in today's extremely low interest rate environment. Lloyds has very little exposure to PIIGS (Portugal, Ireland, Italy, Greece and Spain), and we believe it is a great investment for our shareholders.

ROHM, a Japanese-based semiconductor manufacturer, was the top detractor for the quarter and year, falling 5% and 30%, respectively. The first-half results were weaker than we expected, largely due to depressed domestic audio-visual (e.g. TVs, video recorders and cameras) equipment sales. Slowing phone handset demand in Europe also weighed on performance. Both sales and profits were below the company's original estimates, and management lowered full-year forecasts. ROHM plans to enact some cost-cutting initiatives, including a staff reduction of approximately 5% over the next two years. In addition, management intends to shut down and/or consolidate some facilities, especially relating to the Lapis business. These changes should reduce fixed costs by JPY 8.3 billion and lower variable costs by JPY 1.5 billion. Our recent discussions with ROHM's management were encouraging, and we believe the company's new focus on business expansion outside Japan will be positive and could lead to many new opportunities. In our view, this potential, plus a very solid balance sheet, makes ROHM very attractively priced at this time.

During the quarter we sold our position in Reed Elsevier. We purchased three new names, one of which has been owned previously: Check Point Software (Israel), the second-largest IT security company in the world; Christian Dior, a French luxury goods manufacturer; and H&M, a Swedish clothing designer and retailer.

Our geographical composition changed slightly over the past quarter. Our European holdings decreased to approximately 67%, and our Pacific Rim exposure increased to approximately 29%. Our Latin America and North America (Canada) exposure decreased slightly to approximately 3%, and we initiated Middle East exposure of approximately 1% with the purchase of Check Point Software.

We continue to defensively hedge the Fund's currency exposure. Due to the U.S. dollar's weakness relative to other global currencies, we currently hedge four underlying currencies. At quarter-end, approximately 57% of the Australian dollar, 43% of the Swedish krona and 33% of the Swiss franc exposure were hedged. We also continue to hedge the Japanese yen, but due to its recent weakening, we decreased our hedge to approximately 24%.

We would like to thank our shareholders for continuing to support us and our value-investing philosophy.

Happy New Year!

The Oakmark International Small Cap Fund performed well in both absolute and relative terms for the quarter and one-year periods ending December 31, 2012. For the quarter, the Fund returned 9%, compared to 5% for the MSCI World ex U.S. Small Cap Index.¹⁸ For calendar year 2012, the Fund returned 18.4%, and the index returned 17.5%.

The top-contributing stock for both the quarter and the calendar year was Australian food manufacturer Goodman Fielder. Goodman's products include packaged baked goods, spreads, dairy products and dressings. A year ago, Goodman was the largest detractor for the Fund, but management made considerable progress in its turnaround effort during 2012. In the fourth quarter, Goodman announced price increases within its bakery and grocery business—an important milestone given intense price pressure in these businesses over the previous two years. Management remains focused on improving the company's cost structure by closing underperforming bakeries (three in Australia) and investing in larger, more efficient sites. Management is also working to improve the company's distribution costs and increase its product innovation, which should lead to higher margins in the coming years. Goodman recently sold two non-core assets: Integro, a fats and oils business, and Champion Milling, a New Zealand flour maker. This should allow management to focus more attention on its core businesses. We are pleased with the progress Goodman has made in 2012, and we believe that this management team has a clear strategy for continuing to improve the company and its financial performance in the coming years.

The largest detractor from the Fund's performance for the past quarter and year was Japanese gaming company Square Enix Holdings. During the quarter, Square Enix reduced its sales, earnings and profit margin forecasts for the current fiscal year. Though the market anticipated these downward revisions, they were more significant than expected. As an explanation, management cited higher production and operations costs related to major releases of online game services. Other factors included sluggish sales of arcade game consoles and slower-than-expected sales of the high-definition game Sleeping Dogs. Square Enix also faces two other issues: the company is between hardware cycles, and customers can now download games and apps to mobile devices at cheaper prices. Despite these issues, the gaming industry continues to expand. It is the fastest growing entertainment for kids, and women represent its largest growth category. However, the industry's revenues tend to fluctuate, which cause stock prices to shift in turn. Despite its recent setbacks Square Enix remains an attractive investment in our view.

During the quarter, we did not divest from any portfolio holdings, but we added two new names: Amplifon and Morgan Crucible. Headquartered in Italy, Amplifon is the world's largest hearing aid retailer, with a 9% global market share and a 14% market share in the countries in which it competes.

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 Trust's 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 (1-800-625-6275).

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.

Past performance is no guarantee of future results. The performance data quoted represents past performance. Current performance may be lower or higher than the performance data quoted. The investment return and principal value vary so that an investor's shares when redeemed may be worth more or less than the original cost. The performance of the Oakmark International Small Cap Fund does not reflect the 2% redemption fee imposed on shares redeemed within 90 days of purchase. To obtain the most recent month-end performance data, visit oakmark.com.

Current and future portfolio holdings are subject to risk.

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

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

Oakmark Equity and Income Fund may invest 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. An economic downturn could severely disrupt the market in medium- or lower-grade debt securities and adversely affect the value of outstanding bonds and the ability of the issuers to repay principal and interest.

Investing in foreign securities presents risks that in some ways may be greater than in 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 stocks of small 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.
