To Kopp Emerging Growth Fund Shareholders:
Enclosed for your information is a supplement to the prospectus for the American
Century New Opportunities II Fund. A copy of the prospectus accompanied the
proxy materials that you received relating to the proposed reorganization of
your fund. The supplement refers to a redemption fee to be imposed on shares of
the fund purchased after March 1, 2007, and provides additional disclosure
relating to emerging markets investments.
As noted in the proxy materials, the redemption fee will not apply to shares
received by you in the reorganization. The 2% redemption fee will only apply to
additional Investor and Institutional Class shares of New Opportunities II
purchased after March 1, 2007, and sold within 180 days. The fee will not apply
to Class A or C shares. The additional disclosure relating to emerging markets
allows the fund greater flexibility to take advantage of attractive investment
opportunities in less developed countries.
If you have not yet voted your shares, please cast your vote pursuant to the
instructions on the proxy card received with your proxy materials. You may vote
by mail, telephone or the internet. If you have misplaced your proxy card,
please call 1-877-256-6083 to obtain a new one. If you have previously voted and

Prospectus Supplement
New Opportunities II Fund
Supplement dated December 8, 2006 * Prospectus dated March 1, 2006
Effective March 1, 2007, the fund will be subject to a 2% redemption fee on
Investor Class and Institutional Class shares that are redeemed within 180 days
of purchase. The fee will not apply to shares purchased before March 1, 2007, or
to shares purchased with reinvested dividends, regardless of when they are sold.
The following replaces the third paragraph under the heading How does the fund
pursue its investment objective? on page 8.
Although the portfolio managers intend to invest the fund's assets
primarily in U.S. stocks, the fund may invest in securities of foreign
companies, including companies located in emerging markets. Investments in
foreign securities present some unique risks that are more fully described
in the fund's statement of additional information.
The following is added after the fourth paragraph under the heading What are the
principal risks of investing in the fund? on page 9.
Investing in securities of companies located in emerging market countries
generally is also riskier than investing in securities of companies located
in foreign developed countries. Emerging market countries may have unstable
governments and/or economies that are subject to sudden change. These
changes may be magnified by the countries' emergent financial markets,
resulting in significant volatility to investments in these countries.
These countries also may lack the legal, business and social framework to
support securities markets.
