FUND PROFILE
---------------------------------------------------------
What is the fund's objective?
The fund seeks to provide long-term capital growth and, secondarily,
increasing dividend income through investments in the common stocks of
well-established growth companies.
What is the fund's principal investment strategy?
We will invest at least 65% of total assets in the common stocks of a
diversified group of growth companies. We mostly seek investments in
companies that have the ability to pay increasing dividends through strong
cash flow. We generally look for companies with an above-average rate of
earnings growth and a lucrative niche in the economy that gives them the
ability to sustain earnings momentum even during times of slow economic
growth. As growth investors, we believe that when a company increases its
earnings faster than both inflation and the overall economy, the market will
eventually reward it with a higher stock price.
While most assets will be invested in U.S. common stocks, other securities
may also be purchased, including foreign stocks, futures, and options, in
keeping with fund objectives.
The fund may sell securities for a variety of reasons, such as to secure
gains, limit losses, or redeploy assets into more promising opportunities.
Further information about the fund's investments, including a review of
market conditions and fund strategies and their impact on performance, is
available in the annual and semiannual shareholder reports. To obtain free
copies of either of these documents, call 1-800-638-5660.
What are the main risks of investing in the fund?
As with all equity funds, this fund's share price can fall because of
weakness in the broad market, a particular industry, or specific holdings.
The market as a whole can decline for many reasons, including adverse
political or economic developments here or abroad, changes in investor
psychology, or heavy institutional selling. The prospects for an industry or
company may deteriorate because of a variety of factors, including
disappointing earnings or changes in the competitive environment. In
addition, our assessment of companies held in the fund may prove incorrect,
resulting in losses or poor performance even in a rising market. Finally, the
fund's investment approach could fall out of favor with the investing public,
resulting in lagging performance versus other types of stock funds.
In addition, growth stocks can be volatile for several reasons. Since these
companies usually invest a high portion of earnings in their businesses, they
may lack the dividends of value stocks that can cushion stock prices in a

---------------------------------------------------------
falling market. Also, earnings disappointments often lead to sharply falling
prices because investors buy growth stocks in anticipation of superior
earnings growth.
Foreign stock holdings are subject to the risk that some holdings may lose
value because of declining foreign currencies or adverse political or
economic events overseas. Investments in futures and options, if any, are
subject to additional volatility and potential losses.
As with any mutual fund, there can be no guarantee the fund will achieve its
objective.
How can I tell if the fund is appropriate for me?
Consider your investment goals, your time horizon for achieving them, and
your tolerance for risk. If you are willing to accept the risk of investing
in established growth stocks in an effort to achieve long-term capital
growth, the fund could be appropriate for you. This fund should not represent
your complete investment program or be used for short-term trading purposes.
The fund can be used in both regular and tax-deferred accounts, such as IRAs.
How has the fund performed in the past?
The bar chart showing calendar year returns and the average annual total
return table indicate risk by illustrating how much returns can differ from
one year to the next and over time. Fund past performance is no guarantee of
future returns.
The fund can also experience short-term performance swings, as shown by the
best and worst calendar quarter returns during the years depicted in the
chart.
