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 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:

For the share classes listed below, you would pay the following if you did not redeem your shares:

Class 529-B	207	617	1,052	2,033
Class 529-C	206	614	1,047	2,246

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 investment
results. During the most recent fiscal year, the fund's portfolio turnover rate
was 62% of the average value of its portfolio.

Principal investment strategies

As a balanced fund with global scope, the fund seeks to invest in equity and
debt securities around the world that offer the opportunity for growth and/or
provide dividend income, while also constructing the portfolio to protect
principal and limit volatility. The fund will allocate its assets among various
countries, including the United States (but in no fewer than three countries).
Under normal market conditions, the fund will invest significantly (at least 40%
of its net assets - unless market conditions are not deemed favorable by the
fund's investment adviser, in which case the fund would invest at least 30% of
its net assets) in issuers outside the United States.

The fund's ability to invest in issuers outside the United States includes
investing in emerging country issuers.

Normally the fund will maintain at least 45% of the value of its assets in
common stocks and other equity investments. Although the fund's equity
investments focus on medium to larger capitalization companies, the fund's
investments are not limited to a particular capitalization size.

Normally the fund will invest at least 25% of the value of its assets in bonds
and other debt securities (including money market instruments). These will
consist of investment-grade securities (rated Baa3 or better or BBB- or better
by Nationally Recognized Statistical Rating Organizations designated by the
fund's investment adviser or unrated but determined to be of equivalent quality
by the fund's investment adviser).

The fund may invest in bonds and other debt securities, including securities
issued and guaranteed by the U.S. government, securities issued by federal
agencies and instrumentalities and securities backed by mortgages or other
assets. The fund may also invest in securities of governments, agencies,
corporations and other entities domiciled outside the United States. These
investments will typically be denominated in currencies other than U.S. dollars.

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.

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 securities
that, in its opinion, represent good, 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.

Principal risks

This section describes the principal risks associated with the fund's principal
investment strategies. 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 be able to
tolerate potentially sharp declines in value.

Market conditions - The prices of, and the income generated by, the common
stocks, bonds and other securities held by the fund may decline due to market
conditions and other factors, including those directly involving the issuers
of securities held by the fund.

Investing in growth-oriented stocks - Growth-oriented stocks may involve larger
price swings and greater potential for loss than other types of investments.

Investing in income-oriented stocks - Income provided by the fund may be reduced
by changes in the dividend policies of, and the capital resources available at,
the companies in which the fund invests.

Investing outside the United States - Securities of issuers domiciled outside
the United States, or with significant operations outside the United States, may
lose value because of adverse political, social, economic or market developments
in the countries or regions in which the issuer operates. These securities may
also lose value due to changes in foreign currency exchange rates against the
U.S. dollar and/or currencies of other countries. Securities markets in certain
countries may be more volatile and/or less liquid than those in the United
States. Investments outside the United States may also be subject to different
settlement and accounting practices and different regulatory, legal and
reporting standards, and may be more difficult to value, than those in the
United States. The risks of investing outside the United States may be
heightened in connection with investments in emerging markets.

Investing in emerging markets - Investing in emerging markets may involve risks
in addition to and greater than those generally associated with investing in
developed countries. For instance, developing countries may have less developed
legal and accounting systems than those in developed countries. The governments
of these countries may be less stable and more likely to impose capital controls,
nationalize a company or industry, place restrictions on foreign ownership and
on withdrawing sale proceeds of securities from the country, and/or impose
punitive taxes that could adversely affect the prices of securities. In addition,
the economies of these countries may be dependent on relatively few industries
that are more susceptible to local and global changes. Securities markets in
these countries can also be relatively small and have substantially lower
trading volumes. As a result, securities issued in these countries may be more
volatile and less liquid, and may be more difficult to value, than securities
issued in countries with more developed economies and/or markets. Additionally,
there may be increased settlement risks for transactions in local securities.
  
Investing in bonds - Rising interest rates will generally cause the prices of
bonds and other debt securities to fall. Longer maturity debt securities may be
subject to greater price fluctuations than shorter maturity debt securities. In
addition, falling interest rates may cause an issuer to redeem, call or
refinance a security before its stated maturity, which may result in the fund
having to reinvest the proceeds in lower yielding securities.

Bonds and other debt securities are subject to credit risk, which is the
possibility that the credit strength of an issuer will weaken and/or an issuer
of a debt security will fail to make timely payments of principal or interest
and the security will go into default. Credit risk is gauged, in part, by the
credit ratings of the securities in which the fund invests. However, ratings are
only the opinions of the rating agencies issuing them and are not guarantees as
to credit quality or an evaluation of market risk.

Investing in mortgage-backed and asset-backed securities - Many types of bonds
and other debt securities, including mortgage-backed securities, are subject to
prepayment risk as well as the risks associated with investing in debt
securities in general. If interest rates fall and the loans underlying these
securities are prepaid faster than expected, the fund may have to reinvest the
prepaid principal in lower yielding securities, thus reducing the fund's income.
Conversely, if interest rates increase and the loans underlying the securities
are prepaid more slowly than expected, the expected duration of the securities
may be extended, reducing the cash flow for potential reinvestment in higher
yielding securities.

Thinly traded securities - There may be little trading in the secondary market
for particular bonds or other debt securities, which may make them more
difficult to value, acquire or sell.

Management - The investment adviser to the fund actively manages the fund's
investments. Consequently, the fund is subject to the risk that the methods and
analyses employed by the investment adviser in this process may not produce the
desired results. This could cause the fund to lose value or its investment
results to lag relevant benchmarks or other funds with similar objectives.

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

Investment results

Information regarding investment results is not available as of the date of this
prospectus because the fund does not have a full calendar year of investment
operations.

[1] A contingent deferred sales charge of 1.00% applies on certain redemptions within one year following purchases of $1 million or more made without an initial sales charge.
