                      FORWARD-LOOKING STATEMENT DISCLOSURE

One of our most important responsibilities as mutual fund managers is to
communicate with shareholders in an open and direct manner. Some of our comments
in our letters to shareholders are based on current management expectations and
are considered "forward-looking statements". Actual future results, however, may
prove to be different from our expectations. You can identify forward-looking
statements by words such as "estimate", "may", "will", "expect", "believe",
"plan" and other similar terms. We cannot promise future returns. Our opinions
are a reflection of our best judgment at the time this report is compiled, and
we disclaim any obligation to update or alter forward-looking statements as a
result of new information, future events, or otherwise.

PRESIDENT'S LETTER

[PHOTO OF JOHN R. RAITT]

DEAR FELLOW SHAREHOLDERS,

Both domestic and international stock markets produced moderate gains in the
first quarter, extending the worldwide recovery in stock prices that began
roughly a year ago. All of our funds had positive returns and achieved new highs
in net asset value during the quarter. We are pleased that our disciplined value
investment style continues to reward our shareholders.

THE ECONOMY AND THE MARKET

The U.S. economy continues to grow at a healthy rate. Low interest rates and low
inflation are fueling this growth. In addition, employment growth accelerated
significantly in the past quarter, and corporate earnings also showed
significant improvement, aided by high productivity growth. Many of these same
factors are also driving strong economic growth internationally.

Despite the mostly positive economic headlines, our outlook for stock returns
remains tempered by valuation. Most broad market indices are up 35% or more in
the past 12 months. We believe U.S. market valuations now broadly reflect
assumptions of sustained, robust economic recovery. While our analysis indicates
that our holdings are priced at discounts to growing business values, finding
new stock ideas that sell at deep discounts has become more difficult. We are
finding more stock values internationally, but discounts to value have narrowed
there, too.

We still believe that stocks' prospective returns are attractive compared to
other asset classes. However, we also believe that higher share valuations make
this a stock pickers' market. Values exist, but they are tougher to find. The
rigors of our disciplined, bottom-up investment process, which focuses on
finding undervalued stocks, help us to take advantage of market volatility and
to unearth value in today's market. Our patient, long-term approach, which helps
us avoid over reacting to short term events, gives us an extra edge.

INDUSTRY GOVERNANCE AND REGULATION

Over the past quarter, the SEC and Congress have proposed several new rules and
regulations for the mutual fund industry in response to abusive practices by
fund companies. We believe in setting high standards for the treatment of our
shareholders, but we also believe that abuses by other fund companies harm
investors and their confidence in our industry. In this spirit, we support and
encourage sensible new rules and regulations to protect fund investors and
enhance fund governance. If you would like to learn more about our position on
these issues, please visit our web site at www.oakmark.com.

Thank you for your continued investment and confidence in the Oakmark Family of
Funds. We welcome your comments and questions. You can reach us via e-mail at

THE OAKMARK AND OAKMARK SELECT FUNDS

AT OAKMARK, WE LOOK FOR STOCKS WITH PRICES LESS THAN 60% OF INTRINSIC VALUE,
WITH INTRINSIC VALUE THAT IS LIKELY TO GROW AND WITH MANAGEMENT THAT ACTS IN THE
INTEREST OF OUTSIDE SHAREHOLDERS. THE COMBINATION OF THESE FACTORS CREATES OUR
BIGGEST COMPETITIVE ADVANTAGE--THE ABILITY TO BE MORE PATIENT THAN MOST
INVESTORS.

"He that is greedy of gain troubleth his own house." Book of Proverbs

It was a big quarter for the word "greed." It was frequently used in courtrooms
explaining the behavior of former CEOs who were standing trial. It was used in
articles about fund companies that courted market timers. It was used in Warren
Buffett's annual letter referencing excessive CEO compensation. And it was used
to explain investors' behavior who are now more interested in buying stocks than
they were a year ago when stocks were much cheaper.

In his book ORIGINS OF THE CRASH,(4) one of my favorite business writers, Roger
Lowenstein, also makes frequent use of the word greed. His cataloging of events
leading up to the 2000 stock market collapse assigns blame to greedy CEOs,
greedy accountants, greedy Wall Street analysts, and greedy investors. Even
though the peak occurred just four years ago, Lowenstein's book serves as a
great reminder of just how extreme the excesses were: during "the first quarter
of 2000, a technology company was going public and doubling every other day--a
speculative orgy without precedent in public markets." The book should be
required reading before anyone is allowed to say that the bubble is now back!
During the real bubble, CEOs overly incentivized by stock options became
exclusively focused on the short term; audits were marketed not just on price
but on leniency; analysts hyped stocks to create banking business; and investors
bought stocks not because of investment merits, but because prices had risen and
they wanted in on the gravy train. Lowenstein says, "The distinction between
self-interest and greed ... in the '90s was utterly lost."

In the investment criteria we list at the top of this report each quarter, we
say we seek to invest with a "management that acts in the interest of outside
shareholders." We have further said that we want them incentivized with stock
ownership, stock options, and bonuses that pay them for increasing business
value. Effectively, we want them to maximize their personal profits by doing
what is most profitable for us, the outside shareholders. One could argue that
by using the dictionary definition of greed--the desire for wealth beyond one's
needs--we are asking management to be greedy. But many times greed and value
maximization do overlap. That's why Gordon Gekko's "Greed is good!" speech to
the shareholders of Teldar Paper didn't sound entirely self-serving. For tough
decisions like downsizing or selling off divisions, as well as for high return
investments that result in a growing business, greed may result in the same
course of action as value maximization. Greed and value maximization, however,
part ways when short-term goals are pursued that cause long-term damage. As
Lowenstein said, in the 90s, "the credo of shareholder value ... became a maxim
not for enhancing business values, a process that occurs only over years, but
for enhancing day-by-day quotations of shares." We have always been troubled by
managements that are more concerned about their stock prices than they are about
building business value. Managements often ask our advice on what they can do to
get a higher stock price. Our answer has remained the same for years, and it's
not necessarily the one they want to hear. "Run the business to maximize
long-term value and invest excess cash in your highest return
opportunities--among the opportunities being evaluated, always include share
repurchase. If you do, the stock price will take care of itself." Anything short
of that is not behaving like an owner. A business owner would never sacrifice
long-term value in exchange for simply having people believe the business is
more valuable today--unless it is being sold! A management focused only on next
year's stock price won't make the necessary investments for long-term success.
That's why we look at management's overall incentives. We want managements to
make high return investments, even when the payoffs won't be evident for several
years. Warren Buffett commented on the short-term focus that can result from an
options-only incentive plan, saying "Who ever washes a rental car?" Options can
help align a manager's interests with the shareholders, but true ownership
creates a better long-term alignment. By focusing on a five-year time frame, we
hopefully avoid most of the managers who aren't washing our cars!

                                   HIGHLIGHTS

  -  At Oakmark, we add value through stock selection rather than macro
     forecasts.

  -  If management maximizes business value growth, their stock price should
     follow.

  -  We don't believe current market valuations indicate a "Bubble Redux."

With so much greed in the air, some of our value peers have sold stocks and
increased their cash position anticipating better opportunities (lower prices)
ahead. We share some of their concerns because by definition, the higher the
market goes, the tougher it is to find stocks that

                                        4
<Page>

will continue achieving high returns. But, we have never shown an ability to add
value through timing the market, or for that matter, through use of any macro
level forecasts. A NEW YORK TIMES headline last month read "Time for Optimism?
Pessimism? Pick Your Gauge." The article contained bull and bear arguments that
each sounded compelling. An investor who read only one side could have been
easily convinced. Last quarter BARRONS ran a story about the likelihood of a
strong rebound in inflation. It was well written and had strong statistical
backing. However, later in the same issue, an interview with a highly successful
fund manager gave an equally sound argument that deflation was right around the
corner!

Usually, a compelling argument can be made for higher or lower stock prices,
higher or lower inflation, economic boom or recession. Not only do we lack the
ability to select the prophetic ones, but over our five-year time frame, their
conclusions generally tend to be less significant than projecting how a specific
business is likely to change. That's why we spend our time at the company
level--trying to identify companies whose futures are being underpriced. We
agree with Lowenstein's comment that "a true analyst is better equipped to
appraise the medium-term future in rough terms than he is to forecast the here
and now with precision." So we don't try to forecast the market--we simply buy
out-of-favor stocks that appear to be selling below growing business values and
hold them until the gap has closed. While it has been hard this year to find new
stocks selling below 60% of value, we believe our existing holdings continue to
sell at a discount and continue to see growth in their value.

When my children were younger, they enjoyed a story called "The Magic Fish" by
Freya Littledale. In this story, a fisherman catches a talking fish that claims
to be a prince and begs for freedom. Upon returning home and telling his wife
that he set the fish free, the fisherman is berated for not getting anything in
return. The wife demands he ask the fish for a new house. The fish delivers, but
the greedy wife keeps asking for more and more until finally the fish takes back
everything. Those who want us to believe that the current stock market is the
"Bubble Redux" would say today's investor is behaving like the greedy wife.
We're not so sure. Seeing two sides to most every story, we would ask if perhaps
those who are waiting for double-digit expected returns while bonds yield only
4% aren't being just as greedy!

The Oakmark Fund increased in value by 1% in the quarter, slightly trailing the
S&P 500. Over the last twelve months, the Fund increased by 33% compared to 35%
for the S&P 500. Though we always strive to do better than the market, we rely
on an investment approach that focuses on risk. That approach generally keeps us
away from the most popular stocks, which means that we tend to add more value
when markets are not unusually strong. We sold three positions this past
quarter. We decided our outlook on Safeway had been too optimistic given the
high percentage of their sales that come from markets that don't yet have
Wal-Mart or other superstore competitors. Though Safeway still looks
undervalued, we believe other companies have less uncertainty and are equally
undervalued. Further, sale of Safeway allowed us to increase our capital loss
carryforward. On the positive side, shares of JC Penney and Guidant achieved our
price targets and were sold. Two new positions were added: Limited Brands,
described below, and Raytheon, which is described on our website.

LIMITED BRANDS (LTD--$20)
LTD is a specialty retailer with well-known brands including Victoria's Secret,
Bath & Body Works, Express, and its namesake, Limited. LTD stock is down from a
high of $28 which was reached four years ago. While Victoria's Secret and Bath &
Body Works have become highly profitable category dominant chains, the other
brands have struggled. Victoria's Secret and Bath & Body Works now account for
two-thirds of LTD's sales and 90% of operating income. Despite this, investors
seem focused on the struggling turnaround efforts in the lesser chains.
Management has intelligently used the cash generated by these businesses,
including a recently completed $1 billion share repurchase (10% of the
outstanding shares). We believe Victoria's Secret and Bath & Body Works are
above-average franchises, are well insulated from Wal-Mart competition, and
should continue growing at above-average rates. Success in the turnarounds of
Limited and Express is possible and would be nice, but isn't assumed in our
outlook. Selling at fifteen times estimated earnings, LTD is being priced as a
below-average business.

The performance data quoted represents past performance. PAST PERFORMANCE DOES
NOT GUARANTEE FUTURE RESULTS. The investment return and principal value will
fluctuate so that an investor's shares, when redeemed, may be worth more or less
than their original cost. Current performance may be lower or higher than the
performance data quoted. Average annual total return measures annualized change,
while total return measures aggregate change. To obtain current month end

* Not annualized

The Oakmark Select Fund increased in value by 2% in the quarter, slightly
exceeding the S&P 500. The Fund's performance was positively affected by
Washington Mutual's 7% return. As the fund's largest holding, Washington
Mutual's performance frequently is the largest contributor to NAV(10) changes.
Our holding that increased the most in the quarter was Toys 'R' Us. We first
bought Toys 'R' Us in early 2000 believing that new management would succeed at
improving the profitability of their toy stores. Although the shopping
experience today is much better, the profits aren't. Fortunately, continued
growth at Babies 'R' Us and growing real estate value underneath the toy stores
has allowed the stock to increase despite disappointing progress on our primary
thesis. This outcome highlights the value of our investment approach. By
investing only when we believe stocks are selling at large discounts to value,
we have benefited from a cushion that Benjamin Graham, the "father of value
investing," referred to as a "margin of safety." While the company's earnings
have fallen far short of our projections, the stock has increased in price, and
we still believe it is selling at a discount to business value. We are pleased
with the steps management is now considering which include a downsizing of the
toy division.

During the quarter we sold our position in Starwood Hotels. We purchased
Starwood a year ago when the Iraq war caused a cutback in travel plans. The
stock, which then troughed at $22, exceeded $40 last quarter. We still like the
business but believe the current quote approximates full business value.
Starwood was replaced in the portfolio with The Gap. We believe Gap is one of
the strongest global apparel names, and we are very pleased with the new
management, led by CEO Paul Pressler. We think that the stores look better,
which is confirmed by higher same-store-sales. Our confidence is growing that
Gap's turnaround will be successful, so despite the higher price, we believe the
stock is very attractive.

Thank you for your continued support,

OUR RESULTS

The Oakmark Small Cap Fund increased 7% for the quarter ended March 31, which
also reflects the calendar year gain. During 2004, the Fund has outperformed the
market averages while also outperforming our primary benchmark, the Russell 2000
Index, which has gained 6% year-to-date. We are pleased with this result because
we believe that absolute positive returns preserve and grow your capital. We are
even more pleased that over the past three-year and five-year periods we have
grown and compounded the capital of our long-term investors at a 12% and 9%
annualized rate, respectively. Please do not think for one moment however, that
those returns are going to lead us to complacency. We began 2004 with a renewed
focus on our goal of continuing to provide consistent returns. While Oscar Wilde
may have said, "Consistency is the last refuge of the unimaginative," we feel
that in the investment business consistently above-average returns requires both
imagination and discipline. We also firmly believe that you, our investors,
sought this consistency and discipline when you elected to partner with us by
committing capital to the fund.

TIDAL CHARTS

Particularly strong performers during the quarter were Central Parking
Corporation, CIBER Inc., Jack in the Box Inc., Levitt Corporation, and Peoples
Bank of Bridgeport. Over time, we have noted that many value stocks have a
tendency to sit for long periods with a huge gap between our assessment of
intrinsic value and the current market price until a catalyst or some other
piece of information triggers a greater appreciation of the opportunity
presented by the gap. Then, the gap narrows and often closes within a very short
period. We mention this sequence of events because it speaks to the importance
of a long-term focus, rather than allowing one's self to be blown about by the
vagaries of changing short-term perceptions that have little to do with a
company's long-term business value. It also speaks to the foolishness of trying
to time the market, especially in today's world of accelerated information
flows.

The worst performer during the quarter was R.G. Barry, which saw its share price
sell-off when it reported a slowdown in sales of its slipper products, along
with the attendant back-up in inventories. We continue to monitor this situation
closely, weighing the statistical cheapness of the investment against a
management that for a continued period has been unable to avoid tripping over
its own feet in executing a turnaround.

                                   HIGHLIGHTS

  -  Gaps between price and value can remain for long periods, but close quickly
     when a catalyst occurs.

  -  Small caps are significantly under-followed by Wall Street, presenting us
     with real opportunity.

  -  Our focus remains the same: to search for businesses trading at a
     margin-of-safety discount to intrinsic value.

Five positions--Central Parking Corporation, Jack in the Box, Optimal Robotics
Corporation, Penn Fed Financial Corporation, and PMI--were sold out during the
quarter. Four of those issues reached our assessment of fair valuation. We sold
one position, Optimal Robotics, after its management changed its strategy to
focus more on management, rather than shareholder, returns. After we exited the
position, management sold the one business that had represented the major
unpinning of our investment thesis. Seven new positions were initiated during
the quarter in American Italian Pasta, Coolbrands International, FTI Consulting,
Levitt Corporation, NeighborCare Inc., PRIMEDIA, Inc., and Watson Wyatt &
Company Holdings. While the buoyant market of 2003 and the beginning of 2004 has
eliminated many compelling values that existed at the beginning of 2003, our
analytical team has diligently examined the "New Low" list as well as other
sources to uncover some very interesting and undervalued situations. We have NOT
undertaken a strategy of turning the portfolio over merely for the sake of
turning the portfolio over. Rather, we have removed issues from the portfolio
because they had reached their valuation targets or our assessments had proven
faulty, and we have been able to replace them with what we believe are more
attractive issues. We also note that our holdings have not appreciated to the
point where a wholesale liquidation is appropriate based on valuation.

We would point out that there IS a reason why we construct portfolios rather
than focus on individual stocks. To use a baseball analogy, ours is a business
of hitting singles and doubles. If there is an occasional home run, that's nice,
but the singles and doubles provide consistent returns over time while allowing
control of the risk we are undertaking. And, we believe that the market and its
participants will present us with other opportunities to buy a lot of very high
quality securities at very reasonable prices. In the interim, we are looking for
one or two really good ideas a year (and are thankful whenever we are able to
find a few more than that).

MAKING SAUSAGE

Is there anything unique about the process of investing in small cap value
stocks? Aside from liquidity issues, perhaps the biggest difference from the
large cap area is a much diminished information flow. This is not because of the
companies themselves, which are oftentimes quite happy to talk to institutional
or even individual investors. Rather, Wall Street research often provides little
information. A company like Microsoft might have twenty different analysts from
the Street following it. For the top two hundred largest capitalization stocks,
it is not unusual to have at least ten analysts from different companies poking
and prodding the news releases and financials, talking to management, and
producing earnings estimates. The information flow on these companies tends to
be huge. And, given that even a blind pig can find an acorn on occasion,
sometimes one or more of the Street analysts will be outliers in their research
and offer an insight that makes it possible to exploit an inefficiency in price,
however briefly. The opposite is true in the small cap arena.

Probably some ten years ago, the Street started pulling back on the number of
companies it covered. Companies like Merrill Lynch, which used to proudly
announce that their analysts followed more companies than any other firm on Wall
Street, have increasingly trimmed back their coverage to following fewer than a
thousand companies. Given that our benchmark is the Russell 2000, that means a
lot of companies are either not being covered or are covered by at best one or
two institutional analysts, often at small regional or second-tier firms. Many
of the companies in The Oakmark Small Cap Fund are followed by one or two
analysts. That presents us with an opportunity.

Of course, another opportunity comes from the nature of the information flow
about these companies. Most large cap companies, followed by an abundance of
Street analysts as well as buy side analysts for institutional investors,
tightly control access to management, including what have become rigidly
scripted investor presentations and guidelines even for the types of questions
investors can ask. Earnings guidance information is now the high point of a
quarter's information, and woe unto the analyst who deviates greatly from that
guidance. What used to pass for analysis has now become information distribution
by what are very close to being "embedded" reporters, with all that that may
subsume.

Contrarily, in the small cap world, analysts get to meet managements, attend
analyst days where there is the opportunity for interchange with many levels of
management, and still tour plants and other operating facilities. Often these
companies do not have a true head of investor relations (the guardian of
relative truth), so one's idea of the intellectual and moral makeup of
managements comes from direct exchange. One also gets the opportunity to learn
about industries and competitors in considerably more depth than one usually
gets from visiting a large cap company.

At Harris Associates, we are blessed with a very high quality group of analysts
who present us with a continuing flow of well-researched, interesting ideas.
While we won't go so far as saying that the portfolio manager could easily be
replaced by a coin-flipping primate, the fundamental work of our analysts makes
our daily jobs considerably easier.

THE FUTURE

One of the nice aspects of our job and the focus of our firm is that as
fundamental value investors, we don't spend a lot of time trying to guess the
future, especially what we have no control over and no ability to assess. We
leave it

                                       15

to others who make their living predicting economic growth or interest rates.
This is probably for the best because we don't think we have any especial talent
in that area, and they may actually be ones where the coin-flipping primate can
truly excel (or perhaps already has, depending on one's opinion of various
commentators). Instead, we plod along, looking to unearth the occasional diamond
in the rough of an investment opportunity. In our favor, the continued and even
intensified focus on short-term events drives many investment analysis and
portfolio management decisions today. Sometimes (actually more than sometimes),
doing nothing is the correct decision if you have confidence in your original
assessment. Regardless, we are not going to do anything different this coming
year from what we have done in the past: searching for business values at that
margin of safety discount to intrinsic value that we like. We remain grateful to
you, our shareholders and partners, for your patience and confidence in
entrusting us with your capital to manage.

QUARTER REVIEW

The Equity and Income Fund produced a return of 4% for the quarter ended March
31. This result modestly exceeded the 2% that the Lipper Balanced Fund Index
reported. The fund's return has now bested the Balanced Fund Index in 15 of the
past 17 quarters. While we are competitive individuals who enjoy achieving
relative success, our goal in managing the fund is not to beat a benchmark.
Rather, we seek to earn positive rates of return in all material time periods
while always maintaining an unhedged commitment to common stocks of at least
50%.

The world is exceptionally confusing these days. Issues like the plague of
terrorism, an unusually polarized U.S. election cycle, a synchronized global
economic recovery, historically low interest rates, and troubling corporate
governance issues have combined to make investing based on macro factors
hazardous. Many investors who desire consistent positive returns have attempted
to cope with uncertainty by moving money to hedge funds and investment
partnerships that employ various esoteric strategies. These entities often pay
little attention to the underlying fundamentals of their investments, instead
treating securities more like mathematical abstractions. Hedge funds do,
however, account for an ever-increasing share of trading volume.

We, of course, have our own opinions on macro issues, but we do not make these
opinions central to how we invest your money based on those opinions. Instead,
careful analysis of corporate business values drives our investment decisions.
We have built the fund's record on thousands of decisions concerning individual
securities, and we will continue to expend our energies in that manner. Since
the fund's inception at the end of 1995, it has generated positive results in
all but one calendar year and 25 out of 33 quarters. We hope to improve upon
that record.

HIT AND MISS

In our first 34 reports to shareholders we have written extensively (AD
NAUSEAM?) about our investing philosophy and process. Many reports also waxed
eloquent about our fixed income approach. At the moment we find that we do not
have anything new to say on these topics. Therefore, the remainder of this
report will discuss individual equity holdings. Please recognize, however, that
this does not imply any shift in our investing emphasis but rather a failing of
our creative muse.

To format the discussion, we are shamelessly imitating a relatively new column
of the

                                       20
<Page>

                                   HIGHLIGHTS

  -  Careful analysis of long-term business values drives our investment
     decisions, not opinions about macro issues.

  -  This quarter, we talk about our investing hits and misses, specifically,
     Caremark and First Health.

  -  As always, we continue to focus on companies priced below business value
     with shareholder-oriented management.

WALL STREET JOURNAL titled "Tracking the Numbers/Hit and Miss." This column asks
portfolio managers to describe experiences with one stock position that worked
and one that failed. To make this more topical for our fund report, we will
focus on two stocks that materially affected the fund's recent results.

HIT

Caremark, a pharmacy benefit manager (PBM) based in Birmingham, Alabama.

AVERAGE PRICE WE PAID: $20.37. The stock closed the quarter at $33.25.

WHY WE BOUGHT IT: We began purchasing shares in August 2002. Earlier that summer
the financial press had questioned the accounting treatment of prescription
co-payments by several PBMs, including Caremark. This industry seemed
interesting to us because of the rapid growth rate in pharmaceutical
expenditures, the even faster growth rate of the mail order pharmacy segment,
and the attendant focus on drug cost containment. Caremark itself attracted us
for many reasons, including its strong management team and its large specialty
pharmaceutical business (distribution of expensive biotechnology drugs). 2002
stock market weakness and accounting paranoia (Caremark was an Arthur Anderson
client) gave us the opportunity to invest at a great price.

HOW IT DID: To the date of this letter, Caremark has proven to be an ideal
experience for the fund. The stock remained in a tight trading range for our
first six months of ownership before rallying vigorously in mid-2003. The
company then announced an agreement to acquire another major factor in its
industry, Advance PCS. The market received this news negatively, offering us
another opportunity to increase our holding at favorable prices. At the time of
this writing Caremark has assumed the position of largest stock holding in the
fund.

THE LATEST: Caremark closed on its purchase of Advance PCS on March 24. After
some initial discomfort with this deal, investors warmed to the idea that the
additional scale would produce significant cost advantages. The stock gained 31%
in the March quarter and was the largest single contributor to the fund's
quarterly return.

MISS

First Health, a nationwide outsourcer of healthcare solutions based in Downers
Grove, Illinois.

AVERAGE PRICE WE PAID: $24.15. We sold the stock for an average price of $20.22.

WHY WE BOUGHT IT: We began purchasing shares in January 2002 believing that the
company was unique in offering corporate clients a nationwide healthcare
solution. We thought that investors misunderstood the company, classifying it as
a managed care provider (I.E., an HMO that underwrites health care insurance for
its clients) rather than a company that simply provides health care solutions
without the insurance liability. We also admired management's use of capital.

HOW IT DID: The share price of First Health meandered within a tight range until
November 2003 when the company announced a significant earnings shortfall. The
stock dropped 24% on the news. Subsequently, our research analysts' work on this
industry suggested that the competitive environment for First Health had
deteriorated and that the company's proprietary advantages had dissipated. Since
this change in perception materially affected our reasons for owning the stock,
we sold it.

THE LATEST: First Health shares appear to have stabilized in the low $20s as
investors await more data that would provide clarity concerning the competitive
landscape.

So what do we take from this? Both of our subject companies are in the business
of helping corporate America deal with rising health costs, both have
shareholder-oriented, entrepreneurial management teams, and both have particular
service offerings with a claim to a proprietary position. What changed was that
the competitive position of Caremark actually strengthened while First Health's
weakened. In today's hyper-competitive world economy, it may be that business
values themselves are less stable than in the past.

In closing, we would once again like to thank our investors for entrusting us
with their assets.

FELLOW SHAREHOLDERS,

The Oakmark Global Fund gained 4% for the three-month period ending March 31,
2004, compared with the 3% increase for the MSCI World Index and the 4% increase
for the Lipper Global Fund Index.

Over the past twelve months, The Oakmark Global Fund has returned 73%, compared
to the smaller gains of 44% and 47% for the MSCI World Index and the Lipper
Global Fund Index, respectively. Most importantly, since inception the Fund has
returned 17% annualized compared to a 2% decline in the MSCI World Index and 1%
return in the Lipper Global Fund Index.

PORTFOLIO COMPOSITION

We made few changes during the quarter. We sold two companies, L.M. Ericsson
(Sweden) and First Health Group (US). Ericsson, the mobile network equipment
powerhouse, significantly contributed to performance over the past twelve months
as the share price more than tripled before hitting our sell price during the
quarter. We became less comfortable in our assessment of First Health's business
franchise after a very poor earnings announcement, and we sold our entire
position.

We also exchanged our shares in Concord EFS for shares in First Data Corp, who
completed their acquisition this quarter. First Data, along with Diageo, are now
your Fund's largest holdings at just under 5% each of fund assets.

We added one new position during the quarter, Switzerland-based Lonza Group.
Lonza is one of the world's leading suppliers of active ingredients, chemical
intermediates, and biotechnology solutions to the pharmaceutical and
agrochemical industries. Their main businesses are: Exclusive Synthesis,
Biotechnology, Organic Fine Chemicals, and Performance Chemicals.

Currently, Exclusive Synthesis is Lonza's biggest profit generator. The business
is based on the outsourcing trend in the life science industry, which entrusts
specialized companies with the manufacturing of advanced intermediates and
active ingredients. Lonza has state-of-the-art, multipurpose plants that can be
adapted to each customer's individual needs. This advanced customization
capability makes them the world's leader in exclusive custom manufacturing for
global life sciences companies.

                                   HIGHLIGHTS

  -  The portfolio is more heavily weighted to international stocks, as we're
     finding more attractive valuations overseas.

  -  High-quality businesses in Europe represent a better risk-reward trade-off
     than in emerging markets.

  -  Despite strong performance, we remain excited about the value and quality
     of the Fund's portfolio.

We purchased the stock during the quarter after the release of disappointing
2003 results caused the share price to weaken. We believe the market is
underestimating the growth potential in both Lonza's Exclusive Synthesis and
Biotechnology segments. On a normalized basis we think Lonza is valued at just
over 10x earnings. Management is also sound with strong shareholder orientation.
We've respected Chairman Sergio Marchionne's ability for a number of years and
applauded his quick decision to replace the operationally-deficient former CEO.

GLOBAL OUTLOOK

Currently, your portfolio is composed of roughly 35% US-listed companies, 47% in
the UK and Europe, 3% in Latin America, and 15% in the Asia Pacific region. As
you've probably surmised from our dwindling US market weighting, we continue to
have difficulty finding new US stocks that are more attractive than current
holdings or new overseas opportunities. However, we continued to increase our
holdings in several US companies during the quarter, namely Burlington Resources
and Waste Management.

Internationally, we continue to find companies that meet our value criteria in a
number of areas, including blue-chip European consumer non-durables (Nestle,
Henkel, and Diageo), pharmaceuticals (Takeda Chemical, Aventis, and
GlaxoSmithKline), and financial services (Australia and New Zealand Bank, Bank
of Ireland, Banca Popolare di Verona, and Julius Baer Holding).

Over the past twelve months, we have seen strong price appreciation around the
globe in equities, fixed income, and natural resources. Many asset classes
formerly (and usually) thought risky, such as junk bonds, emerging markets, and
technology/story stocks, have been the strongest performers. The risk premium we
demand for investing in emerging markets, for example, has all but evaporated in
most cases. In sum, we think high-quality businesses, especially in the UK and
Europe, represent a much more interesting risk-reward relationship.

As an example, let's use Diageo plc, the world's largest spirits company. Diageo
generates tremendous amounts of free cash flow from their high return on capital
business, much of which is returned to shareholders in the form of rising
dividends and share repurchases. In addition the company is well-positioned to
take advantage of the growth of those same emerging markets of which investors
are so currently enamored.

At 14x this year's earnings and a 4% dividend yield, we find Diageo's valuation
too cheap in a relatively dear world. And unlike investing in many emerging
markets, there are also no corporate governance concerns--management is solely
focused on increasing shareholders' wealth.

LOOKING FORWARD

Despite the Fund's strong performance we remain excited about the value and
quality of the names, such as First Data, Diageo and Lonza, in the portfolio. We
thank you for your support.

THE OAKMARK INTERNATIONAL AND
OAKMARK INTERNATIONAL SMALL CAP FUNDS

FELLOW SHAREHOLDERS,

Your Funds ended the quarter with a return of 4% and 7%, respectively, for The
Oakmark International and International Small Cap Funds. This compares to a
return of 4% for the MSCI World ex U.S. Index.(18) The returns were mixed versus
the relevant index primarily due to an underweighted position in the strong
Japanese market.

More importantly, over the past year, your Funds performed 62% and 85%,
respectively, while the MSCI World ex U.S. Index returned 57%.

FAVORABLE CONDITIONS V. SCREAMING BUYS

As equity markets have recovered very strongly over the past year, we no longer
believe the markets are significantly over-sold. However, we do believe a much
more favorable investment climate exists. Notwithstanding the upcoming election
in the U.S. as well as continued fears surrounding terrorism, the world, in our
view, is in pretty good shape.

Growth is very strong in places like North America, Australasia, East Asia, and
India. The UK and "New Europe" are also performing well. Hopefully, "Old Europe"
and Japan (which is showing some signs of life) will also catch the growth wave.
However, we do not believe that either of these two areas are capable of
sustainable economic growth unless bona fide structural reform occurs.

Given the level of per capita income and overall economic improvement in the
developing markets and large population centers like China and India, we believe
we have reached the inflection point where these markets have a significant
impact on the world economy. This provides a nice tail wind for many of the
companies in which your fund is invested.

COMPANY VALUATIONS: THE EARTH IN BALANCE

With a much tamer macroeconomic environment, we are witnessing far less extremes
in global company valuations. In the late 90s we witnessed huge valuation
differentials between tech related and non-tech related stocks. Also, small cap
companies traded at a significant discount to large caps, and emerging markets
were coming off a harsh bear market. Today, though tech stocks are pricey, they
are not as outrageously priced as they were in '99 and '00. The differential in
valuations between foreign large and small cap stocks has evaporated, and
emerging market stocks are back in vogue. In fact, we would argue that in
certain places, such as China, India, and Hong Kong, stocks are now expensive,
which is not all that surprising given the focus these regions have attracted.

                                   HIGHLIGHTS

  -  World equity markets are no longer over-sold, but the investment climate is
     much more favorable.

  -  Economic improvement in developing markets and population centers are
     starting to have a large impact on the global economy.

  -  We're finding value in developed-market blue chips that are high-quality
     businesses.

We have been able to find value in the most obvious types of companies:
developed market blue chips. After years of underperforming, stocks in the
consumer non-durable, pharmaceuticals, and financial service sectors have
lagged, whereas their prospects and valuations have improved. We are very happy
to invest in these quality businesses that fulfill our value definition of being
both high quality as well as inexpensively priced.

* Not annualized

The Oakmark International Fund gained 4% for the quarter, slightly less
than the benchmark indices. The returns were lower than the relevant indices
primarily due to an underweighted position in the strong Japanese market.

For the past twelve months, your Fund is up 62%. Individual securities that
contributed to performance most significantly during the quarter were French
pharmaceutical Aventis; European securities exchange Euronext; and two Mexican
companies, multimedia and broadcasting powerhouse Grupo Televisa and beverage
company Fomento Economico Mexicano ("FEMSA").

The share price of Aventis was driven up during the quarter by an acquisition
bid by Sanofi-Synthelabo, as well as from overtures from Novartis. Management
has responded to the situation in a very shareholder-oriented fashion, and is
working hard to maximize the value of the company.

Euronext is the pan-European exchange comprising Amsterdam, Paris, Brussels, and
Lisbon, as well as the derivatives exchange LIFFE. In 2003, Euronext's operating
profit improved significantly, and the share price has also benefited recently
from the market's delayed recognition of their strong position in clearing and
an increasingly liquid balance sheet.

Positive changes to Televisa's shareholder structure, as well as its continued
positive underlying results, have bolstered the share price. Finally, FEMSA
continues to show strong results from their brewing business (with brands like
Dos Equis and Tecate) as well as from their pan-American soft-drink bottling
operations.

The most significant detractor from quarterly performance was UK pharmaceutical
GlaxoSmithKline. Several of our pharmaceutical holdings underperformed during
the quarter. These companies continue to suffer from intense debate regarding
pricing, disappointing pipelines, and the short-term profit outlook. We continue
to believe these concerns are somewhat overblown and already fully reflected in
share prices. Our long-term expectations for this industry remain positive.
Other underperformers in the portfolio included Lonza (Switzerland) and BMW
(Germany).

We continue to like the quality and price attractiveness of the portfolio. Thank
you for your continued confidence.

* Not annualized

The Oakmark International Small Cap Fund gained 7% for the quarter, slightly
more than the relevant index. For the past twelve months, your Fund is up 85%.

The strongest performers for the quarter included most of our Japanese holdings,
especially brokerage firm Ichiyoshi Securities, ophthalmic (eye) specialist
Santen Pharmaceutical, and the entertainment software firm Square Enix.
Ichiyoshi's share price was buoyed by strong equity markets, and the company
announced they would significantly increase dividend payouts. Santen recently
announced a North American distribution alliance with Johnson & Johnson. Because
Santen's superior anti-infective product has strong growth potential in the
U.S., the alliance should provide the necessary distribution scale and know-how
to penetrate the market.

Stock selection in France also positively affected the Fund's returns for the
quarter. LISI and Carbone Lorraine showed particularly strong share price
performance.

Another strong performer was UK-based retailer Carpetright plc., which continues
to demonstrate the strength of its business model. The company generated strong
cash flows despite a difficult operating environment in 2003.

The most significant detractors from quarterly performance were capital
equipment manufacturer Alfa Laval (Sweden), financial services provider Julius
Baer Holding (Switzerland), and Baycorp Advantage (Australia). The declines in
these stock prices were minor on an absolute basis.

We continue to like the quality and price attractiveness of the portfolio. Thank

THE OAKMARK FAMILY OF FUNDS

NOTES TO FINANCIAL STATEMENTS--(UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

The following are the significant accounting policies of The Oakmark Fund
("Oakmark"), The Oakmark Select Fund ("Select"), The Oakmark Small Cap Fund
("Small Cap"), The Oakmark Equity and Income Fund ("Equity and Income"), The
Oakmark Global Fund ("Global"), The Oakmark International Fund
("International"), and The Oakmark International Small Cap Fund ("Int'l Small
Cap") collectively referred to as "the Funds", each a series of Harris
Associates Investment Trust (the "Trust"), a Massachusetts business trust, which
is registered as an investment company under the Investment Company Act of 1940.
These policies are in conformity with accounting principles generally accepted
in the United States of America ("GAAP"). The presentation of financial
statements in conformity with GAAP requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates and assumptions.

CLASS DISCLOSURE--

Each Fund offers two classes of shares: Class I Shares and Class II Shares.
Class I Shares are offered to the general public. Class II Shares are offered to
certain retirement plans such as 401(k) and profit sharing plans. Class II
Shares pay a service fee at the annual rate of .25% of average net assets of
Class II Shares of the Funds. This service fee is paid to an administrator for
performing the services associated with the administration of such retirement
plans.

Income, realized and unrealized capital gains and losses and expenses of the
Funds that are not directly attributable to a specific class of shares are
prorated among the classes based on the relative net assets of each class.
Expenses directly attributable to a class of shares are recorded to the specific
class.

REDEMPTION FEES--

Each Fund imposes a short-term trading fee on redemptions of Class I Shares held
for 90 days or less to offset two types of costs to the Fund caused by
short-term trading: portfolio transaction and market impact costs associated
with erratic redemption activity and administrative costs associated with
processing redemptions. The fee is 2% of the redemption value and is deducted
from the redemption proceeds and retained by the Fund. The "first-in, first-out"
(FIFO) method is used to determine the holding period.

SECURITY VALUATION--

Securities traded on securities exchanges and over-the-counter securities are
valued at the last sales price on the day of valuation, or lacking any reported
sales that day, at the most recent bid quotation. Securities traded on the
NASDAQ National Market are valued at the NASDAQ Official Closing Price ("NOCP"),
or lacking an NOCP, at the most recent bid quotation on the NASDAQ National
Market. Debt obligations and money market instruments maturing in more than 60
days from the date of purchase are valued at the latest bid quotation. Debt
obligations and money market instruments maturing in less than 61 days from the
date of purchase are valued on an amortized cost basis which approximates market
value. Options are valued at the last reported sale price on the day of
valuation, or lacking any reported sales that day, at the mean of the most
recent bid and ask quotations. Securities for which quotations are not readily
available, or securities which may have been affected by a significant event
after the price was determined, and other assets are valued at a fair value as
determined by or under the direction of pricing committees established by the
Board of Trustees. Securities traded in foreign markets are valued using prices
reported by local foreign markets. The Funds' net asset values are determined at
the time of the close of the New York Stock Exchange. The pricing committees
will evaluate movements in the U.S. markets after the close of foreign markets
and may adjust security prices to reflect changes in reaction to U.S. markets as
determined by a third party model. At March 31, 2004, the Funds held one
security for which a quotation was not readily available, and no securities
which may have been affected by a significant event after the price was
determined.

FOREIGN CURRENCY TRANSLATIONS--

Values of investments and other assets and liabilities denominated in foreign
currencies are translated into U.S. dollars using the mean of the bid and offer
prices of such currencies at the time of valuation. Purchases and sales of
investments and dividend and interest income are converted at the prevailing
rate of exchange on the respective dates of such transactions.

The Funds do not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from the fluctuations
arising from changes in market prices of securities held. Such fluctuations are
included with the net realized gain or loss from securities.

Net realized gains or losses on foreign currency transactions arise from sales
of foreign currencies, currency gains or losses realized between the trade and
settlement dates on securities transactions, the difference between the amounts
of dividends, interest, and foreign withholding taxes recorded and the U.S.
dollar equivalent of the amounts actually received or paid, and the realized
gains or losses resulting from the portfolio and transaction hedges. Net
unrealized foreign exchange gains and losses arise from changes in the fair
value of assets and liabilities, other than investments in securities at fiscal
year end, resulting from changes in exchange rates.

</Table>

SECURITY TRANSACTIONS AND INVESTMENT INCOME--

Security transactions are accounted for on the trade date (date the order to buy
or sell is executed) and dividend income is recorded on the ex-dividend date.
Interest income and expenses are recorded on an accrual basis. Bond discount is
accreted and premium is amortized over the expected life of each applicable
security. Withholding taxes on foreign dividends have been provided for in
accordance with the Funds' understanding of the applicable country's tax rules
and rates. Corporate gains taxes on the appreciation of certain foreign
securities have been accrued for in accordance with the Funds' understanding of
the applicable country's tax rules and rates, and are recorded as Deferred
Foreign Taxes on the Statements of Operations. Net realized gains and losses on
investments are determined by the specific identification method. Net realized
gains and losses on investments are determined by the specific identification
method.

FORWARD FOREIGN CURRENCY CONTRACTS--

The Funds' currency transactions are limited to transaction hedging and
portfolio hedging involving either specific transactions or portfolio positions.

The contractual amounts of forward foreign exchange contracts do not necessarily
represent the amounts potentially subject to risk. The measurement of the risks
associated with these instruments is meaningful only when all related and
offsetting transactions are considered. Risks arise from the possible inability
of counter parties to meet the terms of their contracts and from movements in
currency values. At March 31, 2004, the Funds had no forward foreign currency
contracts outstanding.

DISTRIBUTIONS TO SHAREHOLDERS--

Income, dividends and capital gains distributions are determined in accordance
with federal income tax regulations, which may differ from GAAP. To the extent
the tax and book differences are permanent in nature, such amounts are
reclassified among paid in capital, undistributed net investment income and
accumulated undistributed net realized gain (loss). Those differences are
primarily related to foreign currency transactions, deferral of losses on wash
sales, and character of capital loss carryforwards. The Funds also utilize, when
appropriate, earnings and profits distributed to shareholders on redemption of
shares as a part of the dividends paid deduction for income tax purposes.

SHORT SALES--

The Fund may sell a security it does not own in anticipation of a decline in the
fair value of that security. When the Fund sells a security short, it must
borrow the security sold short and deliver it to the broker-dealer through which
it made the short sale. A gain, limited to the price at which the Fund sold the
security short, or loss, unlimited in size, will be recognized upon the
termination of a short sale. At March 31, 2004, the Funds had no securities sold
short.

ACCOUNTING FOR OPTIONS--

When a Fund writes an option, the premium received by the Fund is recorded as a
liability and is subsequently adjusted to the current market value of the option
written. Premiums received from writing options that expire are recorded by the
Fund on the expiration date as realized gains from option transactions. The
difference between the premium and the amount paid on effecting a closing
purchase transaction, including brokerage commissions, is also treated as a
realized gain, or if the premium is less than the amount paid for the closing
purchase transaction, as a realized loss. If a call option is exercised, the
premium is added to the proceeds from the sale of the underlying security or
currency in determining whether the Fund has realized a gain or a loss. If a put
option is exercised, the premium reduces the cost basis of the security or
currency purchased by the Fund. In writing an option, the Fund bears the market
risk of an unfavorable change in the price of the security or currency
underlying the written option. Exercise of an option written by the Fund could
result in the Fund selling or buying a security or currency at a price different
from the current market value. Options written by the Funds do not give rise to
counterparty credit risk, as they obligate the Funds, not their counterparties,
to perform. At March 31, 2004, the Funds had no written options outstanding.

When a Fund purchases an option, the premium paid by the Fund is recorded as an
asset and is subsequently adjusted to the current market value of the option
purchased. Purchasing call options tends to increase the Fund's exposure to the
underlying instrument. Purchasing put options tends to decrease the Fund's
exposure to the underlying instrument. Premiums paid for purchasing options
which expire are treated as realized losses. Premiums paid for purchasing
options which are exercised or closed are added to the amounts paid or offset
against

                                       64
<Page>

the proceeds on the underlying security to determine the realized gain or loss.
The risk associated with purchasing put and call options is potential loss of
the premium paid. At March 31, 2004, the Funds held no options.

COMMITTED LINE OF CREDIT--

The Funds have an unsecured committed line of credit with Investors Bank & Trust
Company ("IBT") in the amount of $450 million. Borrowings under that arrangement
bear interest at .45% above the Federal Funds Effective Rate. There were no
borrowings during the period ended March 31, 2004.

REPURCHASE AGREEMENTS--

Each Fund, through its custodian, receives delivery of the underlying securities
collateralizing repurchase agreements. It is each Fund's policy that the market
value of the collateral be at least equal to 105% of the repurchase price,
including interest. Each Fund's adviser is responsible for determining that the
value of the collateral is at all times at least equal to 105% of the repurchase
price, including interest. Repurchase agreements could involve certain risks in
the event of default or insolvency of the counterparty including possible delays
or restrictions upon a Fund's ability to dispose of the underlying securities.

EXPENSE OFFSET ARRANGEMENT--

IBT serves as custodian of the Funds. IBT's fee may be reduced by credits which
are an earnings allowance calculated on the average daily cash balances each
Fund maintains with IBT. Credit balances used to reduce the Funds' custodian
fees, if any, would be reported as a reduction of total expenses in the
Statements of Operations.

SECURITY LENDING--

Each Fund except Oakmark may lend its portfolio securities to broker-dealers and
banks. Any such loan must be continuously secured by collateral in cash or cash
equivalents maintained on a current basis in an amount at least equal to the
fair value of the securities loaned by the Fund. Collateral is marked to market
and monitored daily. The Fund would continue to receive the equivalent of the
interest or dividends paid by the issuer on the securities loaned, and would
also receive an additional return that may be in the form of a fixed fee or a
percentage of the earnings on the collateral. The Fund would have the right to
call the loan and obtain the securities loaned at any time, and the bank shall
return the securities within five business days or less. In the event of
bankruptcy or other default of the borrower, the Fund could experience delays in
liquidating the loan collateral or recovering the loaned securities and incur
expenses related to enforcing its rights. In addition, there could be a decline
in the value of the collateral or in the fair value of the securities loaned
while the Fund seeks to enforce its rights thereto and the Fund could experience
subnormal levels of income and lack of access to income during that period.

RECLASSIFICATIONS--

Certain amounts have been reclassified to conform with the current presentation.

2. TRANSACTIONS WITH AFFILIATES

Each Fund has an investment advisory agreement with Harris Associates L.P.
("Adviser"). For management services and facilities furnished, the Funds pay the
Adviser monthly fees. Each fee is calculated on the total net assets as
determined at the end of each preceding calendar month. Annual fee rates are as
follows:

The Adviser has entered into agreements with service providers to provide
recordkeeping, processing, shareholder communications and other services to the
Funds. These services would be provided by the Funds if the shares were held in
accounts registered directly with the Funds' transfer agent. Accordingly, the
Funds pay a portion of these fees pursuant to a separate agreement with the
Adviser. These fees are reflected as other shareholder servicing fees in the
Statements of Operations.

The non-interested Trustees of the Trust may participate in the Trust's Deferred
Compensation Plan for Independent Trustees. Participants in the plan may elect
to defer all or a portion of their compensation. Amounts deferred are retained
by the Trust and represent an unfunded obligation of the Trust. The value of
amounts deferred for a participant is determined by reference to the change in
value of Class I shares of one or more of the Funds or a money market fund as
specified by the participant. Benefits under the plan are payable upon
retirement. The interested trustees are not compensated by the Funds.

Revenue Code applicable to regulated investment companies and to distribute all

This material must be preceded or accompanied by a prospectus. To order a
prospectus, which explains management fees and expenses and the special risks of
investing in the funds, visit www.oakmark.com or call 1-800-OAKMARK. Please read
the prospectus carefully before investing.

The discussion of investments and investment strategy of the funds represents
the investments of the funds and the views of fund managers and Harris
Associates L.P., the funds' investment adviser, at the time of this article, and
are subject to change without notice.

The performance data quoted represents past performance. PAST PERFORMANCE DOES
NOT GUARANTEE FUTURE RESULTS. The investment return and principal value will
fluctuate so that an investor's shares, when redeemed, may be worth more or less
than their original cost. Current performance may be lower or higher than the
performance data quoted. Average annual total return measures annualized change,
while total return measures aggregate change. To obtain current month end
performance data call 1-800-OAKMARK.

INVESTING IN VALUE STOCKS PRESENTS THE RISK THAT VALUE STOCKS MAY FALL OUT OF
FAVOR WITH INVESTORS AND UNDERPERFORM GROWTH STOCKS DURING GIVEN PERIODS.

THE OAKMARK SELECT FUND CLOSED TO NEW INVESTORS AS OF 5/4/01.

BECAUSE THE OAKMARK SELECT FUND IS NON-DIVERSIFIED, THE PERFORMANCE OF EACH
HOLDING WILL HAVE A GREATER IMPACT ON THE FUND'S TOTAL RETURN, AND MAY MAKE THE
FUND'S RETURN MORE VOLATILE THAN A MORE DIVERSIFIED FUND.

THE OAKMARK EQUITY & INCOME FUND WILL CLOSE TO CERTAIN NEW INVESTORS AS OF
5/7/04.

EQUITY AND INCOME INVESTS IN MEDIUM- AND LOWER-QUALITY DEBT SECURITIES THAT HAVE
HIGHER YIELD POTENTIAL BUT PRESENT GREATER INVESTMENT AND CREDIT RISK THAN
HIGHER-QUALITY SECURITIES, WHICH 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.

THE OAKMARK GLOBAL FUND AND THE OAKMARK INTERNATIONAL FUND CLOSED TO CERTAIN NEW
INVESTORS AS OF 12/15/03.

THE OAKMARK INTERNATIONAL SMALL CAP FUND CLOSED TO NEW INVESTORS AS OF 5/10/02.

INVESTING IN FOREIGN SECURITIES REPRESENTS RISKS WHICH IN SOME WAY 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 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.

1.   Total return includes change in share prices and in each case includes
     reinvestment of any dividends and capital gain distributions.

     The performance information for Class I shares of The Oakmark Fund, The
     Oakmark Select Fund, The Oakmark Small Cap Fund, The Oakmark Equity &
     Income Fund, The Oakmark Global Fund, The Oakmark International Fund and
     The Oakmark International Small Cap Fund does not reflect the imposition of
     a 2% redemption fee on shares held by an investor for 90 days or less. The
     purpose of this redemption fee is to deter market timers.

2.   Portfolio holdings are subject to change without notice and are not
     intended as recommendations of individual stocks.

3.   During the period since inception (8/4/99 - 3/31/04), IPO's contributed an
     annualized 1.83% to the performance of the Oakmark Global Fund. As the IPO
     environment changes and the total net assets of the Fund grow, the impact
     of IPOs on performance is expected to diminish. "IPO" stands for Initial
     Public Offering, which is the first sale of stock by a company to the
     public.

THE OAKMARK FAMILY OF FUNDS

INVESTMENT PHILOSOPHY

All Oakmark managers follow a consistent investment philosophy--to invest in
companies they believe are trading at a substantial discount to underlying
business value. Critical to this philosophy is to invest with management teams
who are committed to maximizing the company's business value.

THREE KEY TENETS OF OUR INVESTMENT PHILOSOPHY:

1    Buy businesses trading at a significant discount to our estimate of true
     business value.

2    Invest in companies expected to grow shareholder value over time.

3    Invest with management teams who think and act as owners.

INVESTMENT PROCESS

We seek to identify undervalued companies through an intensive, in-house
research process. This process is not based on macro-economic factors, such as
the performance of the economy or the direction of interest rates. Nor is it
based on technical factors, such as the performance of the stock market itself.
And, while some value managers might use only one summary statistic--such as
price-earnings ratio--our investment professionals take a more in-depth approach
using a range of valuation measures appropriate for a specific company or
industry.

From the universe of thousands of equity securities, our team generates
investment ideas through a variety of methods. If a security appears attractive,
detailed quantitative and qualitative research follows. This careful process of
identifying undervalued stocks results in an "approved list."

THE RESULT: a unified effort aimed at identifying the best values in the
marketplace. From the list of approved stocks, each fund manager constructs a
relatively focused portfolio, built on a stock-by-stock basis from the bottom
up.

WHO SHOULD INVEST

Any investor who is seeking a disciplined value manager for the purposes of
growing and diversifying a portfolio should consider one of The Oakmark Funds,
keeping in mind that all equity investments should be considered long-term
investments. As value investors, we recognize that patience is a virtue and
believe that, over the long term, investors are rewarded for their patience. We
generally hold the companies in which we invest for three to five years, a time
horizon that we encourage our shareholders to consider as well.

HOW TO USE VALUE FUNDS IN AN OVERALL PORTFOLIO

Investment styles tend to move in cycles. One style may be in favor for a few
years while the other is out of favor, and vice versa. Diversifying the stock
portion of your portfolio may help reduce overall volatility--and potentially
provide more consistent returns over time.

THE OAKMARK GLOSSARY

BOOK VALUE - A company's common stock equity as it appears on a balance sheet,
equal to total assets minus liabilities, preferred stock, and intangible assets
such as goodwill. A company's book value often differs substantially from
economic value, especially in industries such as media.

BUSINESS VALUE/INTRINSIC VALUE - The perceived or estimated actual value of a
security, as opposed to its current market price or book value. Business value
can be evaluated based on what a knowledgeable buyer would pay for a business if
the company were sold in its entirety.

GROWTH INVESTING - Investors who look for companies based on whether the stock
of a company is growing earnings and/or revenue faster than the industry as a
whole or the overall market. Growth investors generally expect high rates of
growth to persist, and the stock, in turn, to deliver returns exceeding the
market's. A growth mutual fund is generally one that emphasizes stocks believed
to offer above-average growth prospects, with little to no emphasis on the
stock's current price.

M & A (MERGERS & ACQUISITIONS) - Merger: the combining of two or more entities
into one, through a purchase acquisition or a pooling of interests. Acquisition:
can also be called a takeover, and is defined as acquiring control of a
corporation, called a target, by stock purchase or exchange, either hostile or
friendly.

MARKET CAPITALIZATION (MARKET CAP OR CAP) - The market price of an entire
company on any given day, calculated by multiplying the number of shares
outstanding by the price per share.

MOMENTUM INVESTING - Approach to investing based on the belief that stock price
trends are likely to continue. Momentum investors tend to buy stocks that have
been outperforming the market and to sell those stocks when their relative
performance deteriorates. Momentum investors do not consider a company's
underlying value or fundamentals in their investment decisions.

MULTIPLE - A ratio used to measure a stock's valuation, usually greater than 1.
Sometimes used to mean price/earnings ratio.

P/B OR PRICE-TO-BOOK RATIO - A stock's capitalization divided by its book value.
The value is the same whether the calculation is done for the whole company or
on a per-share basis.

P/E OR PRICE-TO-EARNINGS RATIO - The most common measure of a stock's valuation.
It is equal to a stock's capitalization divided by its after-tax earnings over a
12-month period. The value is the same whether the calculation is done for the
whole company or on a per-share basis. Equivalently, the cost an investor in a
given stock must pay per dollar of current annual earnings. Also called earnings
multiple.

SHARE REPURCHASE - Program through which a corporation buys back its own shares
in the open market, typically an indication that the corporation's management
believes the stock price is undervalued.

VALUE INVESTING - Investors who utilize valuation measures such as business
value (including growth rate), price/earnings ratio, price/book ratio, and yield
to gauge the attractiveness of a company. Managers who employ a value investment
style believe that the true, underlying value of a company is not reflected in
its current share price, and, over time, the price has potential to increase as
the market recognizes the overall value of the business. Value stocks sell at
relatively low prices in relation to their underlying business value, earnings,
or book value.

   Stocks become undervalued for a variety of reasons, including an overall
market decline, or when a specific industry falls into disfavor and investors
view all companies in that industry in the same light. Consequently, an
individual company's stock price may fall, even though it may be only
temporarily affected by the industry's problems and its underlying value has
remained unchanged.

"X TIMES EARNINGS" ("12 TIMES EARNINGS") - Another way to express a stock's
price-to-earnings (P/E) ratio. A stock with a P/E ratio of 12 sells at 12 times
earnings.
