SELECT FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Select seeks long-term capital growth by investing primarily in common
stocks.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

The fund managers look for stocks of large companies that they believe will
increase in value over time.

The fund managers use a growth investment strategy developed by American
Century that looks for companies whose earnings and revenues are not only
growing, but growing at a successively faster, or accelerating, pace.
Accelerating growth is shown, for example, by growth that is faster this
quarter than last or faster this year than the year before.

Using American Century's extensive computer database, the fund managers
track financial information for thousands of companies to research and
select the stocks they believe will be able to sustain accelerating growth.
This strategy is based on the premise that, over the long term, the stocks
of companies with accelerating earnings and revenues have a
greater-than-average chance to increase in value. This aggressive investment
strategy, which pursues superior long-term returns for fund shareholders,
also results in the risks described in the next section.

The fund managers do not attempt to time the market. Instead, they intend to
keep Select essentially fully invested in stocks regardless of the movement
of stock prices generally. When the fund managers believe that it is
prudent, they also may invest assets in nonleveraged futures and options.
"Nonleveraged" means that the fund may not invest in futures and options
where it would be possible to lose more than the fund invested. Futures and
options can help the fund's cash assets remain liquid while performing more
like stocks.

Additional information about Select's investments is available in its annual
and semiannual reports. In these reports you will find a discussion of the
market conditions and investment strategies that significantly affected the
fund's performance during the most recent fiscal period. You may get these
reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

* The value of Select's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities that the fund
owns will go up and down depending on the performance of the companies
that issued them, general market and economic conditions, and investor
confidence.

* The fund managers will buy a large amount of a company's stock quickly,
and often will dispose of it quickly if the company's earnings or
revenues decline. While the fund managers believe this strategy provides
substantial appreciation potential over the long term, in the short term
it can create a significant amount of share price volatility. This
volatility can be greater than that of the average stock fund.

* As with all funds, your shares may be worth more or less at any given
time than the price you paid for them. As a result, it is possible to
lose money by investing in the fund.

* An investment in the fund is not a bank deposit, and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any
other government agency.

* Market performance tends to be cyclical and, in the various cycles,
certain investment styles may fall in and out of favor. If the market
is not favoring the fund's style, the fund's gains may not be as big as,
or its losses may be bigger than, other equity funds using different
investment styles.

* Although the fund managers intend to invest the fund's assets primarily
in U.S. stocks, Select may invest in securities of foreign companies.
Foreign investment involves additional risks, including fluctuations in
currency exchange rates, less stable political and economic structures,
reduced availability of public information, and lack of uniform financial
reporting and regulatory practices similar to those that apply in the
United States. These factors make investing in foreign securities
generally riskier than investing in U.S. stocks.

In summary, Select is intended for investors who seek long-term capital
growth through an aggressive equity fund and who are willing to accept the
risks associated with the fund's investment strategy.

ULTRA FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Ultra seeks long-term capital growth by investing primarily in common
stocks.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

The fund managers look for stocks of medium to large companies that they
believe will increase in value over time. The fund managers use a growth
investment strategy developed by American Century that looks for companies
whose earnings and revenues are not only growing, but growing at a
successively faster, or accelerating, pace. Accelerating growth is shown,
for example, by growth that is faster this quarter than last or faster this
year than the year before.

The fund managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep Ultra essentially fully invested in
stocks regardless of the movement of stock prices generally. When the fund
managers believe it is prudent, they also may invest assets in nonleveraged
futures and options. "Nonleveraged" means that the fund may not invest in
futures and options where it would be possible to lose more than the fund
invested. Futures and options can help the fund's cash assets remain liquid
while performing more like stocks.

Additional information about Ultra's investments is available in its annual
and semiannual reports. In these reports you will find a discussion of the
market conditions and investment strategies that significantly affected the
fund's performance during the most recent fiscal period. You may get these
reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

* The value of Ultra's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities that the fund
owns will go up and down depending on the performance of the companies
that issued them, general market and economic conditions, and investor
confidence.

* As with all funds, your shares may be worth more or less at any given
time than the price you paid for them. As a result, it is possible to
lose money by investing in the fund.

* An investment in the fund is not a bank deposit, and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any
other government agency.

* Although the fund managers intend to invest the fund's assets primarily
in U.S. stocks, Ultra may invest in securities of foreign companies.
Foreign investment involves additional risks, including fluctuations in
currency exchange rates, less stable political and economic structures,
reduced availability of public information, and lack of uniform financial
reporting and regulatory practices similar to those that apply in the
United States. These factors make investing in foreign securities
generally riskier than investing in U.S. stocks.

In summary, Ultra is intended for investors who seek long-term capital
growth through an aggressive equity fund and who are willing to accept the
risks associated with the fund's investment strategy.

* to reinvest dividends in additional shares

* to exchange into the Investor Class shares of other American Century
funds

* to redeem your shares

The following table describes the fees and expenses you will pay if you buy

(2) Other expenses, which include the fees and expenses of the fund's
independent directors and their legal counsel, as well as interest,
were less than 0.005% for the most recent fiscal year.

Tax-Managed Value Fund

October 27, 2000
Investor Class

[american century logo (reg.sm)]
American Century

TAX-MANAGED VALUE FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Tax-Managed Value seeks long-term capital growth by investing primarily in
common stocks while attempting to minimize the impact of federal taxes on
shareholder returns.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

The fund managers use a value investment strategy to look for stocks of
medium to large companies the fund managers believe are undervalued at the
time of purchase. Companies may be undervalued due to market declines, poor
economic conditions, actual or anticipated bad news regarding the issuer or
its industry, or because they have been overlooked by other investors. To
identify these companies, the fund managers look for companies with
earnings, cash flows and/or assets that may not be reflected accurately in
the companies' stock prices.

To minimize taxable distributions, the fund managers employ the following
tax-sensitive techniques that may sometimes be inconsistent with the fund's
objective of long-term capital growth.

* The fund managers seek to minimize realized capital gains by keeping
portfolio turnover relatively low and generally holding its investments
for longer periods.

* The fund managers seek to minimize realized capital gains when selling
the shares of a specific company by analyzing the fund's holdings of that
company's shares to determine which shares were purchased at what price
and typically selling those shares bought at the highest price.

* The fund managers may seek to minimize realized capital gains by selling
securities to realize capital losses. Realized capital losses can offset
realized capital gains, thereby reducing capital gain distributions to
the fund's shareholders.

* When appropriate, the fund managers may seek to minimize taxable dividend
income by investing in stocks with lower dividend yields.

While the fund seeks to minimize taxable distributions to shareholders, it
may realize taxable gains and earn some dividends. For example, the fund
managers may elect to sell a security, even if the sale results in a taxable
gain, if they determine the tax impact of the sale is outweighed by other
factors. Such other factors may include the investment risk of holding the
security or the availability of a replacement security that has a better
potential return. In addition, redemptions by shareholders could make it
necessary for the fund to sell securities, potentially resulting in capital
gains. Under certain circumstances, payment of the redemption price may be
made in whole or in part by a distribution in kind of securities from the
fund in lieu of cash, at the fund managers' discretion.

Investors who frequently redeem their shares generate additional
transactional costs for the fund and may cause the fund to recognize capital
gains and greater brokerage commissions that must be borne by the fund's
remaining shareholders. To encourage long-term investing, the fund applies a
2.0% redemption fee to shares held for less than one year. The fees will be
paid directly to the fund and will be used to help reimburse the fund for
costs incurred by the fund when buying and selling securities.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

* As with all funds, your shares may be worth more or less at any given
time than the price you paid for them. As a result, it is possible to
lose money by investing in the fund.

* An investment in the fund is not a bank deposit, and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any
other government agency.

* The value of Tax-Managed Value's shares depends on the value of the
stocks and other securities it owns. The value of the individual
securities the fund owns will go up and down depending on the performance
of the companies that issued them, general market and economic conditions,
and investor confidence.

* If the market does not consider the individual stocks purchased by the
fund to be undervalued, the value of the fund's shares may not rise as
high as other funds and may decline, even if stock prices generally are
increasing.

Tax-Managed Value American Century Investments

* While the fund seeks to minimize taxable distributions to shareholders,
it nonetheless may realize capital gains on the sale of investment
securities and earn dividend income. For example, the fund managers may
elect to sell a security even if it results in a taxable gain if they
determine the tax impact of the sale is outweighed by other factors (such
as the investment risk of the security). Federal tax laws require the
fund to make distributions of such gains and income to its shareholders
on at least an annual basis. Distributions may be taxable as ordinary
income, capital gains or a combination of the two.

In summary, Tax-Managed Value is intended for investors who seek long-term
capital growth on an after-tax basis and who are willing to accept the risks
associated with the fund's investment strategy.

4. WHAT ARE THE FUND'S FEES AND EXPENSES?

There are no sales loads, fees or other charges

* to buy fund shares directly from American Century
* to reinvest dividends in additional shares

THE FUND CHARGES A REDEMPTION/EXCHANGE FEE OF 2.0% OF THE VALUE OF THE
SHARES SOLD WITHIN ONE YEAR OF THEIR PURCHASE.

The following table describes the fees and expenses you will pay if you buy
and hold shares of the fund.

SHAREHOLDER FEES
(FEES PAID DIRECTLY FROM YOUR INVESTMENT)

Redemption/Exchange Fee
(as a percentage of amount redeemed/exchanged)

Shares held less than one year(1) 2.0%
Shares held for one year or more None

(1) The fees withheld from redemption proceeds are paid to the fund.

ANNUAL FUND OPERATING EXPENSES
(EXPENSES THAT ARE DEDUCTED FROM FUND ASSETS)

Management Fee 1.10%(1)
Distribution and Service (12b-1) Fees None
Other Expenses 0.00%(2)
Total Annual Fund Operating Expenses 1.10%

(1) The fund has a stepped fee schedule. As a result, the fund's
management fee rate generally decreases as fund assets increase.

(2) Other expenses, which include the fees and expenses of the fund's
independent directors and their legal counsel, as well as interest,
were less than 0.005% for the most recent fiscal year.

EXAMPLE

Assuming you . . .

* invest $10,000 in the fund
* redeem all of your shares at the end of the periods shown below
* earn a 5% return each year
* incur the same operating expenses as shown above

. . . your cost of investing in the fund would be:

1 year 3 years
$320 $349

You would pay the following expenses if you did not redeem or
exchange your shares at the end of the periods shown below:

1 year 3 years
$112 $349

VEEDOT FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Veedot seeks long-term capital growth.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

The fund uses a systematic, highly automated approach to common stock
investing developed by American Century. This approach relies heavily on
quantitative tools to identify attractive investment opportunities,
regardless of company size, industry type or geographic location, on a
disciplined, consistent basis.

These tools include a fundamental process that screens thousands of publicly
traded securities to identify those that meet the fund's strict, proprietary
growth requirements.

The fund's methodology also attempts to identify companies whose share price
patterns suggest that they are likely to either rise or fall in price
(commonly referred to as technical analysis). This technical analysis is
particularly oriented to identifying attractive price patterns for companies
meeting the growth requirements mentioned above. These would be candidates
for purchase. Conversely, companies whose share price patterns suggest they
are likely to decline in price would be candidates for sale, if owned by the
fund. On occasion, the process may look favorably on a company whose share
price pattern appears attractive even though the company looks less
attractive based on the growth screen.

The fund managers do not attempt to time the market. Instead, they intend to
keep the fund essentially fully invested in stocks regardless of the
movement of stock prices generally. However, at the fund managers'
discretion, the fund may invest up to 100% of its assets in U.S. government
securities if the fund's investment methodology fails to generate sufficient
investment ideas or to respond to adverse market, economic, political or
other conditions. The fund may not achieve its investment objectives while
taking such a temporary defensive position.

Additional information about Veedot's investments is available in its
semiannual report. In this report, you will find a discussion of the market
conditions and investment strategies that significantly affected the fund's
performance during the most recent fiscal period. You may get this report at
no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

* The process driving the fund is specifically designed to respond quickly
to changing stock market conditions. As a result, the fund's portfolio
turnover may be significantly higher than that of many other funds. This
heavy turnover, perhaps as much as 200-300% per year or more, could
result in relatively high commission costs, substantial capital gain
realizations for the fund, and capital gains tax liabilities for the
fund's shareholders.

* The value of the fund's shares depends on the value of
the stocks and other securities it owns. The value of the individual
securities the fund owns will go up and down depending on the performance
of the companies that issued them, general market and economic
conditions, and investor confidence.

* The fund managers may buy a large amount of a company's stock quickly,
and often will dispose of it quickly if it no longer meets their
investment criteria. While the managers believe this strategy provides
substantial appreciation potential over the long term, in the short term
it can create a significant amount of share price volatility. This
volatility can be greater than that of the average stock fund.

* As with all funds, your shares may be worth more or
less at any given time than the price you paid for them. As a result,
it is possible to lose money by investing in the fund.

* The fund is nondiversified. This means that the fund managers may choose
to invest in a relatively small number of securities. If so, a price
change in any one of these securities may have a greater impact on the
fund's share price than would be the case if the fund were diversified.
Although the fund managers expect it will ordinarily satisfy the
requirements for a diversified fund, its nondiversified status gives
them more flexibility to invest heavily in the most attractive
companies identified by the fund's methodology.

* Although the fund managers intend initially to invest the fund's assets
primarily in U.S. stocks, the fund may invest in securities of foreign
companies. To the extent a fund invests in foreign securities, the
overall risk of the fund

Veedot American Century Investments

could be affected. Foreign investment involves additional risks,
including fluctuations in currency exchange rates, less stable
political and economic structures, reduced availability of public
information, and lack of uniform financial reporting and regulatory
practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than
investing in U.S. stocks.

* Market performance tends to be cyclical, and in the various cycles,
certain investment styles may fall in and out of favor. If the market
is not favoring the style embedded in the fund's heavily automated
investment process, the fund's gains may not be as big as, or its
losses may be bigger than, other equity funds using different
investment styles.

In summary, Veedot is intended for investors who seek long-term capital
growth through an aggressive equity fund and who are willing to accept the
risks associated with the fund's investment strategy.

4. WHAT ARE THE FUND'S FEES AND EXPENSES?

There are no sales loads, fees or other charges

* to buy fund shares directly from American Century
* to reinvest dividends in additional shares

THE FUND CHARGES A REDEMPTION FEE OF 2.0% OF THE VALUE OF THE SHARES SOLD
WITHIN FIVE YEARS OF THEIR PURCHASE. This redemption fee is retained by the
fund. It is intended to discourage short-term investment in the fund as well
as to decrease the negative impact that short-term investors have on the
shareholders remaining in the fund Otherwise, there are no fees or charges
to exchange into the Investor Class shares of other American Century funds
or to redeem your shares. The following table describes the fees and
expenses you will pay if you buy and hold shares of the fund.

SHAREHOLDER FEES (FEES PAID DIRECTLY FROM YOUR INVESTMENT)

Redemption/Exchange Fee 2.0%(1)
(as a percentage of amount redeemed/exchanged)

(1) Applies only to shares held for less than five years

ANNUAL OPERATING EXPENSES
(EXPENSES THAT ARE DEDUCTED FROM FUND ASSETS)

Management Fee(1) 1.50%
Distribution and Service (12b-1) Fees None
Other Expenses(2) 0.00%
Total Annual Fund Operating Expenses 1.50%

(1) The fund has a stepped fee schedule. As a result, the fund's
management fee rate generally decreases as fund assets increase.

(2) Other expenses, which include the fees and expenses of the fund's
independent directors and their legal counsel, as well as interest,
are expected to be less than 0.005% for the current fiscal year.

EXAMPLE

Assuming you. . .

* invest $10,000 in the fund
* redeem all of your shares at the end of the periods shown below
* earn a 5% return each year
* incur the same operating expenses as shown above

. . . your cost of investing in the fund would be:

VISTA FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Vista seeks long-term capital growth by investing primarily in common
stocks.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

The fund managers look for stocks of companies that they believe will
increase in value over time. A majority of the stocks selected are issued by
medium- and smaller-sized companies, although the fund may own stock of
larger companies, too. The fund managers use a growth investment strategy
developed by American Century that looks for companies whose earnings and
revenues are not only growing, but growing at a successively faster, or
accelerating, pace. Accelerating growth is shown, for example, by growth
that is faster this quarter than last or faster this year than the year
before.

The fund managers do not attempt to time the market. Instead, they intend to
keep Vista essentially fully invested in stocks regardless of the movement
of stock prices generally. When the fund managers believe that it is
prudent, they also may invest assets in nonleveraged futures and options.
"Nonleveraged" means that the fund may not invest in futures and options
where it would be possible to lose more than the fund invested. Futures and
options can help the fund's cash assets remain liquid while performing more
like stocks.

Additional information about Vista's investments is available in its annual
and semiannual reports. In these reports you will find a discussion of the
market conditions and investment strategies that significantly affected the
fund's performance during the most recent fiscal period. You may get these
reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

* The value of Vista's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities that the fund
owns will go up and down depending on the performance of the companies that
issued them, general market and economic conditions, and investor
confidence.

* The fund managers will buy a large amount of a
company's stock quickly, and often will dispose of it quickly if the
company's earnings or revenues decline. While the fund managers believe this
strategy provides substantial appreciation potential over the long term, in
the short term it can create a significant amount of share price volatility.
This volatility can be greater than that of the average stock fund.

* As with all funds, your shares may be worth more or less at any given
time than the price you paid for them. As a result, it is possible to lose
money by investing in the fund.

* An investment in the fund is not a bank deposit, and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other
government agency.

* Market performance tends to be cyclical and, in the various cycles,
certain investment styles may fall in and out of favor. If the market is not
favoring the fund's style, the fund's gains may not be as big as, or its
losses may be bigger than, other equity funds using different investment
styles.

* Because Vista generally invests in smaller companies than our similarly
managed Ultra and Growth funds, it may be more volatile, and subject to
greater short-term risk, than those funds.

* Although the fund managers intend to invest the fund's assets primarily
in U.S. stocks, Vista may invest in securities of foreign companies.
Foreign investment involves additional risks, including fluctuations in
currency exchange rates, less stable political and economic structures,
reduced availability of public information, and lack of uniform financial
reporting and regulatory practices similar to those that apply in the
United States. These factors make investing in foreign securities generally
riskier than investing in U.S. stocks.

Vista American Century Investments

In summary, Vista is intended for investors who seek long-term capital
growth through an aggressive equity fund and who are willing to accept the
risks associated with the fund's investment strategy.

BALANCED FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Balanced seeks long-term capital growth and current income by investing
approximately 60% of the fund's assets in equity securities and the
remainder in bonds and other fixed-income securities.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

For the equity portion of the Balanced portfolio, the fund managers utilize
quantitative management techniques in a two-step process that draws heavily
on computer technology. In the first step, the fund managers rank stocks,
primarily the 1,500 largest publicly traded companies in the United States
(measured by the value of their stock). These rankings are determined by
using a computer model that combines measures of a stock's value, as well
as measures of its growth potential. To measure value, the managers use
ratios of stock price-to-book value and stock price-to-cash flow, among
others. To measure growth, the managers use, among others, the rate of
growth of a company's earnings and changes in its earnings estimates.

In the second step, the managers use a technique called portfolio
optimization. In portfolio optimization, the managers use a computer model
to build a portfolio of stocks from the ranking described earlier that they
think will provide the optimal balance between risk and expected return.
The goal is to create an equity portfolio that provides better returns than
the S&P 500 without taking on significant additional risk.

The fixed-income portion of the fund's portfolio is invested in a
diversified portfolio of high-grade government, corporate, asset-backed and
similar securities payable in U.S. currency, with a minimum of 25% of the
fund's assets in fixed-income securities. At least 80% of the fixed-income
assets will be invested in securities that, at the time of purchase, are
rated within the three highest categories by a nationally recognized
statistical rating organization. The remaining portion may be invested in
securities rated in the fourth and fifth highest categories. Under normal
market conditions, the weighted average maturity for the fixed-income
portfolio will be in the three- to 10-year range.

Additional information about Balanced's investments is available in its
annual and semiannual reports. In these reports you will find a discussion
of the market conditions and investment strategies that significantly
affected the fund's performance during the most recent fiscal period. You
may get these reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

* The value of Balanced's shares depends on the value of
the stocks, bonds and other securities it owns. The value of the individual
equity securities that the fund owns will go up and down depending on the
performance of the companies that issued them, general market and economic
conditions, and investor confidence. The value of the fund's fixed-income
securities will be affected primarily by rising or falling interest rates
and the continued ability of the issuers of these securities to make
payments of interest and principal as they become due.

* When interest rates change, the fund's share value will be affected.
Generally, when interest rates rise, the fund's share value will decline.
The opposite is true when interest rates decline. The interest rate risk is
higher for Balanced than for funds that have shorter weighted average
maturities, such as money market and short-term bond funds.

* Market performance tends to be cyclical and, in the
various cycles, certain investment styles may fall in and out of favor. If
the market is not favoring the fund's style, the fund's gains may not be as
big as, or its losses may be bigger than, other funds using different
investment styles.

* As with all funds, your shares may be worth more or less at any given
time than the price you paid for them. As a result, it is possible to lose
money by investing in the fund.

* An investment in the fund is not a bank deposit, and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other
government agency.

Balanced American Century Investments

* Although the fund managers intend to invest the fund's assets primarily
in U.S. stocks, Balanced may invest in securities of foreign companies and
governments. Foreign investment involves additional risks, including
fluctuations in currency exchange rates, less stable political and economic
structures, reduced availability of public information, and lack of uniform
financial reporting and regulatory practices similar to those that apply in
the United States. These factors make investing in foreign securities
generally riskier than investing in U.S. stocks.

In summary, Balanced is intended for investors who want an investment that
combines the potential for long-term capital growth with the income produced
from a portfolio of intermediate-term fixed-income securities, and who are
willing to accept the risks associated with the fund's investment strategy.

FUND PERFORMANCE

The following bar chart shows the actual performance of Balanced's Investor
Class shares for each of the last 10 calendar years. The bar chart indicates
the volatility of the fund's historical returns from year to year. The bar

The highest and lowest quarterly returns for the period reflected in the bar
chart are:

Highest Lowest
Balanced 15.95% (4Q 1991) -11.22% (3Q 1990)

The following table shows the average annual total returns of the fund's
Investor Class shares for the periods indicated. The S&P 500 Index and the
Lehman Aggregate Bond Index, unmanaged indices that reflect no operating
costs, are blended as a benchmark for performance comparisons.

1 YEAR 5 YEARS 10 YEARS LIFE OF FUND(1)

AVERAGE ANNUAL TOTAL RETURNS (PERIOD ENDED SEPTEMBER 30, 2000)

Blended Index(2) 10.77% 15.60% 14.88% 13.86%(3)

(1) The inception date for Balanced is October 20, 1988.

(2) The blended index is a combination of two widely known indices in
proportion to the approximate asset mix of the fund. Accordingly, 60% of
the blended index consists of the performance of the S&P 500 Index,
which represents the equity portion of the fund, and 40% of the blended
index consists of the Lehman Aggregate Bond Index, which represents the
fixed-income portion.

4. WHAT ARE THE FUND'S FEES AND EXPENSES?

There are no sales loads, fees or other charges

* to buy fund shares directly from American Century

* to reinvest dividends in additional shares

* to exchange into the Investor Class shares of other American Century fund

* to redeem your shares

Balanced Fund Profile

ANNUAL FUND OPERATING EXPENSES
(EXPENSES THAT ARE DEDUCTED FROM FUND ASSETS)

Management Fee 0.90%(1)

Distribution and Service (12b-1) Fees None

Other Expenses 0.00%(2)

Total Annual Fund Operating Expenses 0.90%

(1) Based on expenses incurred during the fund's most recent fiscal year
had the reduced fee been in effect. The fund has a stepped fee schedule.
As a result, the fund's management fee rate generally decreases as fund
assets increase.

(2) Other expenses, which include the fees and expenses of the fund's
independent directors and their legal counsel, as well as interest, were
less than 0.005% for the most recent fiscal year.

EXAMPLE

Assuming you . . .

* invest $10,000 in the fund
* redeem all of your shares at the end of the periods shown below
* earn a 5% return each year
* incur the same operating expenses as shown above

. . . your cost of investing in the fund would be:

1 year 3 years 5 years 10 years

$92 $286 $497 $1,104

Of course, actual costs may be higher or lower. Use this example
to compare the costs of investing in other funds.

HIGH-YIELD FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

High-Yield seeks high current income by investing in a diversified portfolio
of high-yielding corporate bonds, debentures and notes. As a secondary
objective, the fund seeks capital appreciation, but only when consistent
with the primary objective of maximizing current income.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

The fund managers invest the fund's assets primarily in lower-rated debt
securities, which are subject to greater credit risk and consequently pay
higher yields. Securities of this type are subject to substantial risks
including price volatility, liquidity risk and default risk. You should
carefully assess the risks associated with an investment in the fund.

Under normal market conditions, the fund managers will maintain at least
80% of the fund's total assets in high-yielding corporate bonds and other
debt instruments (including convertible and preferred securities). The
remaining assets may be invested in common stocks or other equity-related
securities. The fund managers buy securities that are below investment
grade, including so-called junk bonds. Issuers of these securities often
have short financial histories or have questionable credit.

Up to 40% of the fund's total assets may be invested in fixed-income
obligations of foreign issuers. Under normal market conditions, the fund
may invest up to 20% of its assets, and for temporary defensive purposes, up
to 100% of its assets, in short-term money market instruments.

The purple bar in the following chart shows the authorized credit quality
range for the fund.

QUALITY
--------------------------------------------
HIGH QUALITY

MIG-1 MIG-2 MIG-3
SP-1 SP-2 SP-3
AAA AA A BBB BB B CCC CC C D
---HIGH YIELD ------------------------ [purple bar]
--- INVESTMENT GRADE ---[dk. gray bar]--- --- NON-INVESTMENT GRADE ---[lt. gray bar]

Additional information about High-Yield's investments is available in its
annual and semiannual reports. In these reports you will find a discussion
of the market conditions and investment strategies that significantly
affected the fund's performance during the most recent fiscal period. You
may get these reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

* The value of High-Yield's shares depends on the value of the securities
it owns and the income they produce. When interest rates change, the fund's
share value will be affected. Generally, when interest rates rise, the
fund's share value will decline. The opposite is true when interest rates
decline. This interest rate risk is higher for High-Yield than for funds
that have shorter weighted average maturities, such as money market and
short-term bond funds.

* Issuers of high-yield securities are more vulnerable to real or perceived
economic changes (such as an economic downturn or a prolonged period of
rising interest rates), political changes or adverse developments specific
to the issuer. Adverse economic, political or other developments may be more
likely to cause an issuer of lower-quality bonds to default on its principal
and interest obligations.

* The market for lower-quality securities is generally less liquid than the
market for higher-quality securities.

* Adverse publicity and investor perceptions, as well as new or proposed
laws, also may have a greater negative impact on the market for
lower-quality securities.

* High-Yield can invest up to 40% of its assets in securities of foreign
companies. Foreign securities can have certain unique risks, including
fluctuations in currency exchange rates, unstable political and economic
structures, reduced availability of public information, and the lack of
uniform financial reporting and regulatory practices similar to those that
apply to U.S. issuers.

* As with all funds, your shares may be worth more or less at any given
time than the price you paid for them. As a result, it is possible to lose
money by investing in the fund.

* An investment in the fund is not a bank deposit, and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other
government agency.

High-Yield American Century Investments

In summary, High-Yield is intended for investors who seek current income by
investing in a diversified portfolio of high-yielding corporate bonds,
debentures and notes and who are willing to accept the risks associated with
the fund's investment strategy.

LIMITED-TERM BOND FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Limited-Term Bond seeks income from investments in corporate bonds and
other debt obligations.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

The fund buys quality, short-term corporate bonds and other debt securities.
Corporate bonds generally are issued by companies to finance existing
operations or to expand their business. Under normal market conditions, the
fund managers will invest most of the fund's assets in investment-grade
securities. The remainder will be invested in short-term money market
instruments.

The fund managers actively manage the fund, adjusting its weighted average
portfolio maturity in response to expected changes in interest rates. If
interest rates are expected to rise, the weighted average maturity of the
fund will be shortened to protect its net asset value from the effects of
falling bond prices. If interest rates are expected to fall, the weighted
average maturity will be increased to take advantage of potentially
increasing bond prices.

The weighted average maturity of the fund is expected to be five years or
less.

Additional information about Limited-Term Bond's investments is available in
its annual and semiannual reports. In these reports you will find a
discussion of the market conditions and investment strategies that
significantly affected the fund's performance during the most recent fiscal
period. You may get these reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

* When interest rates change, the fund's share value will be affected.
Generally, when interest rates rise, the fund's share value will decline.
The opposite is true when interest rates decline. This interest rate risk is
higher for Limited-Term Bond than for funds that have shorter weighted
average maturities, such as money market funds.

* The fund may invest part of its assets in securities rated
in the lowest investment-grade category (for example, Baa or BBB). Although
these securities are considered investment grade, the issuers of these
securities are more likely to pose a credit risk, that is, to have problems
making interest and principal payments than issuers of higher-rated
securities.

* As with all funds, your shares may be worth more or less at any given
time than the price you paid for them. As a result, it is possible to lose
money by investing in the fund.

* An investment in the fund is not a bank deposit, and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other
government agency.

In summary, Limited-Term Bond is intended for investors who seek a
competitive level of income with limited price volatility.

Investor Class shares for each full calendar year since the fund's inception

INTERMEDIATE-TERM BOND FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Intermediate-Term Bond seeks a competitive level of income from investments
in corporate bonds and other debt obligations.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

The fund managers buy quality, short- to intermediate-term corporate bonds
and other debt securities. Corporate bonds generally are issued by companies
to finance existing operations or to expand their business. Under normal
market conditions, the fund managers will invest most of the fund's assets
in investment-grade securities. The remainder will be invested in short-term
money market instruments.

The weighted average maturity of the fund is expected to be three to 10
years.

Additional information about Intermediate-Term Bond's investments is
available in its annual and semiannual reports. In these reports you will
find a discussion of the market conditions and investment strategies that
significantly affected the fund's performance during the most recent fiscal
period. You may get these reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

* When interest rates change, the fund's share value will
be affected. Generally, when interest rates rise, the fund's share value
will decline. The opposite is true when interest rates decline. This
interest rate risk is higher for Intermediate-Term Bond than for funds that
have shorter weighted average maturities, such as money market and
short-term bond funds.

* The fund may invest part of its assets in securities rated in the lowest
investment-grade category (for example, Baa or BBB). Although these
securities are considered investment grade, the issuers of these securities
are more likely to pose a credit risk, that is, to have problems making
interest and principal payments than issuers of higher-rated securities.

* As with all funds, your shares may be worth more or less at any given
time than the price you paid for them. As a result, it is possible to lose
money by investing in the fund.

* An investment in the fund is not a bank deposit, and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other
government agency.

In summary, Intermediate-Term Bond is intended for investors who seek a
higher level of current income than is generally available from shorter-term
corporate and government securities and who are willing to accept a greater
degree of price fluctuation.

BOND FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Bond seeks a high level of income from investments in corporate bonds and
other debt obligations.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

The fund buys quality, intermediate- and longer-term corporate bonds and
other debt securities. Corporate bonds generally are issued by companies to
finance existing operations or to expand their business. Under normal market
conditions, the fund managers will invest most of the fund's assets in
investment-grade securities. The remainder will be invested in short-term
money market instruments.

Although there is no weighted average maturity requirement for this fund, it
will invest primarily in intermediate- and long-term bonds. It is
anticipated that under normal market conditions, the weighted average
maturity will be between eight and 20 years.

Additional information about Bond's investments is available in its annual
and semiannual reports. In these reports you will find a discussion of the
market conditions and investment strategies that significantly affected the
fund's performance during the most recent fiscal period. You may get these
reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

* When interest rates change, the fund's share value will be affected.
Generally, when interest rates rise, the fund's share value will decline.
The opposite is true when interest rates decline. The interest rate risk is
higher for Bond than for funds that have shorter weighted average
maturities, such as money market and short-term and intermediate-term bond
funds.

* The fund may invest part of its assets in securities rated in the lowest
investment-grade category (for example, Baa or BBB). Although these
securities are considered investment grade, the issuers are more likely to
pose a credit risk, that is, to have problems making interest and principal
payments than issuers of higher-rated securities.

* As with all funds, your shares may be worth more or less at any given
time than the price you paid for them. As a result, it is possible to lose
money by investing in the fund.

* An investment in the fund is not a bank deposit, and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other
government agency.

In summary, Bond is intended for investors who seek higher income than is
generally provided by money market or short- and intermediate-term
securities and who can accept the greater price volatility associated with
longer-term bonds.
