EXAMPLE

This 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 in the fund 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, that all
dividends and capital gain distributions are reinvested, and that the fund's
operating expenses remain the same. Although your actual costs may be higher or
lower, based on these assumptions, your costs would be:

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 30%
of the average value of its portfolio.

Principal investment strategies

The fund seeks to invest primarily in common stocks of companies that appear to
offer superior opportunities for capital growth and most of which have a history
of paying dividends. In addition, the fund may invest significantly in
securities of issuers domiciled outside the United States and Canada and not
included in the Standard & Poor's 500 Composite Index.

The fund relies on the professional judgment of its investment adviser to make
decisions about the fund's portfolio investments. The basic investment
philosophy of the investment adviser is to seek to invest in attractively valued
companies that, in its opinion, represent above-average, long-term investment
opportunities. The investment adviser believes that an important way to
accomplish this is through fundamental analysis, which may include meeting with
company executives and employees, suppliers, customers and competitors.
Securities may be sold when the investment adviser believes that they no longer
represent relatively attractive investment opportunities. The investment adviser
uses a system of multiple portfolio counselors in managing the fund's assets.
Under this approach, the portfolio of the fund is divided into segments managed
by individual counselors who decide how their respective segments will be
invested.

Principal risks

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.

Investors in the fund should have a long-term perspective and, for example, be
able to tolerate potentially sharp declines in value.

The prices of, and the income generated by, the common stocks and other
securities held by the fund may decline in response to certain events taking
place around the world, including those directly involving the issuers whose
securities are owned by the fund; conditions affecting the general economy;
overall market changes; local, regional or global political, social or economic
instability; governmental or governmental agency responses to economic
conditions; and currency, interest rate and commodity price fluctuations.

<PAGE>

Investments in securities issued by entities based outside the United States may
be subject to the risks described above to a greater extent. These investments
may also be affected by currency fluctuations and controls; different
accounting, auditing, financial reporting, disclosure, regulatory and legal
standards and practices; expropriation; changes in tax policy; greater market
volatility; different 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 developing countries. Investments
in securities issued by entities domiciled in the United States may also be
subject to many of these risks.

You should consider how this fund fits into your overall investment program.

Your investment in the fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
governmental agency, entity or person.

Payments to broker-dealers and other financial intermediaries

If you purchase shares of the fund through a broker-dealer or other financial
intermediary (such as a bank), the fund and the fund's distributor or its
affiliates may pay the intermediary for the sale of fund shares and related

broker-dealer or other intermediary and your individual financial adviser to
recommend the fund over another investment. Ask your individual financial
adviser or visit your financial intermediary's website for more information.

EXAMPLE

This 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 in the fund 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, that all
dividends and capital gain distributions are reinvested, and that the fund's
operating expenses remain the same. Although your actual costs may be higher or
lower, based on these assumptions, your costs would be:

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 30%
of the average value of its portfolio.

Principal investment strategies

The fund seeks to invest primarily in common stocks of companies that appear to
offer superior opportunities for capital growth and most of which have a history
of paying dividends. In addition, the fund may invest significantly in
securities of issuers domiciled outside the United States and Canada and not
included in the Standard & Poor's 500 Composite Index.

The fund relies on the professional judgment of its investment adviser to make
decisions about the fund's portfolio investments. The basic investment
philosophy of the investment adviser is to seek to invest in attractively valued
companies that, in its opinion, represent above-average, long-term investment
opportunities. The investment adviser believes that an important way to
accomplish this is through fundamental analysis, which may include meeting with
company executives and employees, suppliers, customers and competitors.
Securities may be sold when the investment adviser believes that they no longer
represent relatively attractive investment opportunities. The investment adviser
uses a system of multiple portfolio counselors in managing the fund's assets.
Under this approach, the portfolio of the fund is divided into segments managed
by individual counselors who decide how their respective segments will be
invested.

Principal risks

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.

Investors in the fund should have a long-term perspective and, for example, be
able to tolerate potentially sharp declines in value.

The prices of, and the income generated by, the common stocks and other
securities held by the fund may decline in response to certain events taking
place around the world, including those directly involving the issuers whose
securities are owned by the fund; conditions affecting the general economy;
overall market changes; local, regional or global political, social or economic
instability; governmental or governmental agency responses to economic
conditions; and currency, interest rate and commodity price fluctuations.

<PAGE>

Investments in securities issued by entities based outside the United States may
be subject to the risks described above to a greater extent. These investments
may also be affected by currency fluctuations and controls; different
accounting, auditing, financial reporting, disclosure, and regulatory and legal
standards and practices; expropriation; changes in tax policy; greater market
volatility; different 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 developing countries. Investments
in securities issued by entities domiciled in the United States may also be
subject to many of these risks.

You should consider how this fund fits into your overall investment program.

Your investment in the fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
governmental agency, entity or person.

accomplish this is through fundamental analysis, which may include meeting with
company executives and employees, suppliers, customers and competitors.
Securities may be sold when the investment adviser believes that they no longer
represent relatively attractive investment opportunities. The investment adviser
uses a system of multiple portfolio counselors in managing the fund's assets.
Under this approach, the portfolio of the fund is divided into segments managed
by individual counselors who decide how their respective segments will be
invested.
