Example.

The Example is intended to help you compare the cost of investing in
the Fund with the cost of investing in other mutual funds. The example assumes
that you invest $10,000 for the time periods indicated and then redeem all of
your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same.

Although your actual returns and costs may be higher or lower, based on these assumptions your expenses would be:

Expense Example Oakmark International Fund (USD $)	Class I	Class II
Expense Example, With Redemption, 1 Year	108	148
Expense Example, With Redemption, 3 Years	337	459
Expense Example, With Redemption, 5 Years	585	792
Expense Example, With Redemption, 10 Years	1,294	1,735

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs and may result in higher taxes when Fund
shares are held in a taxable account. These costs, which are not reflected in
Annual Fund Operating Expenses or in the Example, affect the Fund's performance.
During the most recent fiscal year, the Fund's portfolio turnover rate was 45%
of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY

The Fund invests primarily in a diversified portfolio of common stocks of
non-U.S. companies. The Fund may invest in non-U.S. markets throughout the
world, including emerging markets. Ordinarily, the Fund will invest in the
securities of at least five countries outside the U.S. There are no geographic
limits on the Fund's non-U.S. investments. The Fund may invest in securities of
large-, mid-, and small-capitalization companies.

The Fund uses a value investment philosophy in selecting equity securities. This
investment philosophy is based upon the belief that, over time, a company's
stock price converges with the company's intrinsic or true business value. By
"true business value," we mean an estimate of the price a knowledgeable buyer
would pay to acquire the entire business. We believe that investing in
securities priced significantly below their true business value presents the
best opportunity to achieve the Fund's investment objective.

The Fund's investment adviser, Harris Associates L.P. (the "Adviser"), uses this
value philosophy to identify companies that it believes have discounted stock
prices compared to the companies' true business values. In assessing such
companies, the Adviser looks for the following characteristics, although not all
of the companies selected will have these attributes: (1) free cash flows and
intelligent investment of excess cash; (2) earnings that are growing and are
reasonably predictable; and (3) high level of manager ownership.

Key Tenets of the Oakmark Investment Philosophy:

1. Buy businesses that are trading at a significant discount to the Adviser's
estimate of the company's intrinsic value. At the time the Adviser buys a
company, the Adviser wants the company's stock to be inexpensive relative to
what it believes the entire business is worth.

2. Invest with companies expected to grow shareholder value over time. Value
investors can sometimes fall into the trap of buying a stock that is inexpensive
for a reason-because the company just does not grow. The Adviser looks for good
quality, growing businesses with positive free cash flow and intelligent
investment of cash.

3. Invest with management teams that think and act as owners. The Adviser seeks
out companies with management teams that understand the dynamics of per share
value growth and are focused on achieving such growth. Stock ownership and
incentives that align managements' interests with those of shareholders are key
components of this analysis.

In making its investment decisions, the Adviser uses a "bottom-up" approach
focused on individual companies, rather than focusing on specific economic
factors or specific industries. In order to select investments that meet the
criteria described above, the Adviser uses independent, in-house research to
analyze each company. As part of this selection process, the Adviser's analysts
typically visit companies and conduct other research on the companies and their
industries.

Once the Adviser determines that a stock is selling at a significant discount
and that the company has the additional qualities mentioned above, the Adviser
may consider buying that stock for the Fund. The Adviser usually sells a stock
when the price approaches its estimated worth. This means the Adviser sets
specific "buy" and "sell" targets for each stock held by the Fund. The Adviser
also monitors each holding and adjusts those price targets as warranted to
reflect changes in a company's fundamentals.

The Adviser believes that holding a relatively small number of stocks allows its
"best ideas" to have a meaningful impact on the Fund's performance. Therefore,
the Fund's portfolio typically holds thirty to sixty stocks rather than
hundreds.

PRINCIPAL INVESTMENT RISKS

As an investor in the Fund, you should have a long-term perspective and be able
to tolerate potentially wide fluctuations in the value of your Fund shares. Your
investment in the Fund is subject to risks, including the possibility that the
value of the Fund's portfolio holdings may fluctuate in response to events
specific to the companies in which the Fund invests, as well as economic,
political or social events in the U.S. or abroad. As a result, when you redeem
your Fund shares, they may be worth more or less than you paid for them.

Although the Fund makes every effort to achieve its objective, it cannot
guarantee it will attain that objective. The principal risks of investing in the
Fund are:

Market Risk. The Fund is subject to market risk-the risk that securities markets
and individual securities will increase or decrease in value. Market risk
applies to every market and every security. Security prices may fluctuate widely
over short or extended periods in response to market or economic news and
conditions, and securities markets also tend to move in cycles. If there is a
general decline in the securities markets, it is possible your investment may
lose value regardless of the individual results of the companies in which the
Fund invests. The magnitude of up and down price or market fluctuations over
time is sometimes referred to as "volatility," which, at times, can be
significant. In addition, different asset classes and geographic markets may
experience periods of significant correlation with each other. As a result of
this correlation, the securities and markets in which the Fund invests may
experience volatility due to market, economic, political or social events and
conditions that may not readily appear to directly relate to such securities,
the securities' issuer or the markets in which they trade.

Common Stock Risk. Common stocks are subject to greater fluctuations in market
value than other asset classes as a result of such factors as a company's
business performance, investor perceptions, stock market trends and general
economic conditions. The rights of common stockholders are subordinate to all
other claims on a company's assets including debt holders and preferred
stockholders; therefore, the Fund could lose money if a company in which it
invests becomes financially distressed.

Focused Portfolio Risk. The Fund's portfolio tends to be invested in a
relatively small number of stocks. As a result, the appreciation or depreciation
of any one security held by the Fund will have a greater impact on the Fund's
net asset value than it would if the Fund invested in a larger number of
securities. Although that strategy has the potential to generate attractive
returns over time, it also increases the Fund's volatility.

Small and Mid Cap Securities Risk. Investments in small and mid cap companies
may be riskier than investments in larger, more established companies. The
securities of smaller companies may trade less frequently and in smaller
volumes, and as a result, may be less liquid than securities of larger
companies. In addition, smaller companies may be more vulnerable to economic,
market and industry changes. As a result, share price changes may be more sudden
or erratic than the prices of other equity securities, especially over the short
term. Because smaller companies may have limited product lines, markets or
financial resources or may depend on a few key employees, they may be more
susceptible to particular economic events or competitive factors than large
capitalization companies.

Value Style Risk. Investing in "value" stocks presents the risk that the stocks
may never reach what the Adviser believes are their full market values, either
because the market fails to recognize what the Adviser considers to be the
companies' true business values or because the Adviser misjudged those values.
In addition, value stocks may fall out of favor with investors and underperform
growth stocks during given periods.

Non-U.S. Securities Risk. Investments in securities issued by entities based
outside the United States involve risks relating to political, social and
economic developments abroad, as well as risks resulting from the differences
between the regulations to which U.S. and non-U.S. issuers and markets are
subject. These risks may result in the Fund experiencing rapid and extreme value
changes due to currency controls; different accounting, auditing, financial
reporting, and legal standards and practices; political and diplomatic changes
and developments; expropriation; changes in tax policy; a lack of available
public information regarding non-U.S. issuers; greater market volatility; a lack
of sufficient market liquidity; differing securities market structures; higher
transaction costs; and various administrative difficulties, such as delays in
clearing and settling portfolio transactions or in receiving payment of
dividends. These risks may be heightened in connection with investments in
issuers located in developing and emerging countries, and in issuers in more
developed countries that conduct substantial business in such developing and
emerging countries. Fluctuations in the exchange rates between currencies may
negatively affect an investment in non-U.S. securities. The Fund may hedge its
exposure to foreign currencies. Although hedging may be used to protect the Fund
from adverse currency movements, the use of such hedges may reduce or eliminate
the potentially positive effect of currency revaluations on the Fund's total
return, and there is no guarantee that the Fund's hedging strategy will be
successful.

Your investment in the Fund is not a deposit in a bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. You may lose money by investing in the Fund. The likelihood of loss may
be greater if you invest for a shorter period of time.

After-tax returns are calculated using the historical highest individual federal
marginal income tax rates and do not reflect the impact of state and local
taxes.  Actual after-tax returns depend on an investor's tax situation and may differ
from those shown. After-tax returns shown are not relevant to investors who hold
their shares through tax-deferred arrangements, such as 401(k) plans, qualified
plans, education savings accounts or individual retirement accounts. In some
cases, the after-tax returns may exceed the return before taxes due to an
assumed tax benefit from any losses on a sale of Fund shares at the end of the
measurement period. After-tax returns are shown only for Class I shares.
After-tax returns for Class II shares will vary from returns shown for Class I.
