CAPITAL PRESERVATION FUND
1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?
Capital Preservation is a money market fund that seeks maximum safety and
liquidity, and to pay shareholders the highest rate of return consistent
with this objective.
2. WHAT IS THE FUND'S INVESTMENT STRATEGY?
The fund managers buy very short-term U.S. Treasury securities that are
guaranteed by the direct full faith and credit pledge of the U.S.
government.
The fund managers may purchase securities in a number of different ways to
seek higher rates of return. For example, by using when-issued and forward
commitment transactions, the fund managers may purchase securities in
advance to generate additional income.
Additional information about Capital Preservation'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?
* 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 seeks to preserve the value of your
investment at $1.00 per share, it is possible to lose money by investing in
the fund.
* Because very short-term securities are among the safest securities
available, the interest they pay is among the lowest for income-paying
securities. Accordingly, the yield on this fund will likely be lower than
funds that invest in longer-term or lower-quality securities.

Preservation's Investor Class shares for each of the last 10 calendar years.

GOVERNMENT AGENCY MONEY MARKET FUND
1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?
Government Agency Money Market seeks to pay the highest rate of return while

The fund managers buy very short-term securities issued by the U.S.
government, its agencies and instrumentalities. The U.S. government provides
varying levels of financial support to these agencies and instrumentalities.

are guaranteed by the direct full faith and credit pledge of the U.S.
government.
The fund managers may purchase securities in a number of different ways to
seek higher rates of return. For example, by using when-issued and forward
commitment transactions, the fund manager may purchase securities in advance

SHORT-TERM TREASURY FUND
1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?
Short-Term Treasury seeks the highest level of current income exempt from
state income tax while maintaining safety of capital.
2. WHAT IS THE FUND'S INVESTMENT STRATEGY?
The fund managers buy short-term U.S. Treasury securities guaranteed by the
direct full faith and credit pledge of the U.S. government.
The fund managers also may buy short-term securities issued by the U.S.
government, its agencies and instrumentalities. The U.S. government provides
varying levels of financial support to these agencies and instrumentalities.
The fund managers may invest up to 35% of the fund's total assets in these
securities.
The fund managers may purchase securities in a number of different ways to
seek higher rates of return. For example, by using when-issued and forward
commitment transactions, the fund managers may purchase securities in
advance to generate additional income.
The weighted average maturity of the fund is expected to be between 13
months and three years.
Additional information about Short-Term Treasury'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?
* Interest rate changes affect the fund's share value. 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
Short-Term Treasury than for funds that have shorter weighted average
maturities, such as money market funds.
* As with all funds, your shares may be worth more or less at any given time
than the price you paid for them. If you sell your shares when the value is
less than the price you paid, you will lose money.
* 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, Short-Term Treasury is intended for investors who seek the
highest level of current income exempt from state income tax while
maintaining safety of capital and who are willing to accept the risks
associated with the fund's investment strategy.

investing in the fund, that you may want to consider before you invest.

GNMA FUND
1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?
GNMA seeks high current income while maintaining liquidity and safety of
principal by investing primarily in GNMA certificates.
2. WHAT IS THE FUND'S INVESTMENT STRATEGY?
The fund managers primarily buy certificates issued by the Government
National Mortgage Association (GNMA). Unlike many other mortgage-backed
securities, the timely payment of principal and interest on these
certificates is guaranteed by GNMA. GNMA's payment guarantee is stronger
than most other government agencies' because it is backed by the full faith
and credit of the U.S. government. This means that the fund managers receive
the fund's share of payments regardless of whether the ultimate borrowers
make their payments.
The fund managers may also buy U.S. government securities. The U.S.
government, its agencies and instrumentalities issue these securities. These
securities include mortgage-backed securities. The U.S. government's
financial support of these agencies and instrumentalities varies.
The fund managers may purchase securities in a number of different ways to
seek higher rates of return. For example, the fund managers may purchase
securities in advance through when-issued and forward commitment
transactions.
Additional information about GNMA'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 GNMA than for funds that have shorter weighted average
maturities, such as money market funds.
* GNMA invests in mortgage-backed securities. When homeowners refinance
their mortgages to take advantage of declining interest rates, their
existing mortgages are prepaid. The mortgages, which back the securities
purchased by GNMA, may be prepaid in this fashion. Because of this
"prepayment risk," the fund may benefit less from declining interest rates
than other short-term funds.
* As with all funds, your shares may be worth more or less at any given time
than the price you paid for them. If you sell your shares when the value is
less than the price you paid, you will lose money.
* 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, GNMA is intended for investors who seek high current income that
is consistent with investment in GNMA certificates 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 GNMA's Investor
Class shares for each of the last 10 calendar years. The bar chart indicates

LONG-TERM TREASURY FUND
1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?
Long-Term Treasury seeks the highest level of current income exempt from
state income tax.
2. WHAT IS THE FUND'S INVESTMENT STRATEGY?
The fund managers buy long-term U.S. Treasury securities guaranteed by the
direct full faith and credit pledge of the U.S. government.
The fund managers also may buy long-term securities issued by the U.S.
government, its agencies and instrumentalities. The U.S. government provides
varying levels of financial support to these agencies and instrumentalities.
The fund managers may invest up to 35% of the fund's total assets in agency
securities.
The fund managers may purchase securities in a number of different ways to
seek higher rates of return. For example, by using when-issued and forward
commitment transactions, the fund managers may purchase securities in
advance to generate additional income.
The weighted average maturity of the fund is expected to be between 10 and
30 years.
Additional information about Long-Term Treasury'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?
* Interest rate changes affect the fund's share value. 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
Long-Term Treasury than for funds that have shorter weighted average
maturities, such as money market, short-term and intermediate-term bond
funds.
* As with all funds, your shares may be worth more or less at any given time
than the price you paid for them. If you sell your shares when the value is
less than the price you paid, you will lose money.
* 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, Long-Term Treasury is intended for investors who seek the
highest level of current income exempt from state income tax and who are
willing to accept the risks associated with the fund's investment strategy.

SHORT-TERM GOVERNMENT FUND
1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?
Short-Term Government seeks high current income while maintaining safety of
principal.
2. WHAT IS THE FUND'S INVESTMENT STRATEGY?
The fund managers buy short-term securities issued by the U.S. government,
its agencies and instrumentalities, including mortgage-backed securities.
The U.S. government provides varying levels of financial support to these
agencies and instrumentalities. The fund managers also may buy short-term
U.S. Treasury securities guaranteed by the direct full faith and credit
pledge of the U.S. government.
The fund managers may purchase securities in a number of different ways to
seek higher rates of return. For example, by using when-issued and forward
commitment transactions, the fund managers may purchase securities in
advance to generate additional income.
The weighted average maturity of the fund is expected to be three years or
less.
Additional information about Short-Term Government'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?
* Interest rate changes affect the fund's share value. 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
Short-Term Government than for funds that have shorter weighted average
maturities, such as money market funds.
* Short-Term Government invests in mortgage-backed securities. When
homeowners refinance their mortgages to take advantage of declining interest
rates, their existing mortgages are prepaid. The mortgages, which back the
securities purchased by Short-Term Government, may be prepaid in this
fashion. Because of this "prepayment risk," the fund may benefit less from
declining interest rates than other short-term funds.
* As with all funds, your shares may be worth more or less at any given time
than the price you paid for them. If you sell your shares when the value is
less than the price you paid, you will lose money.
* 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, Short-Term Government is intended for investors who seek high
current income that is consistent with investment in securities issued by
the U.S. government and its agencies and who are willing to accept the risks
associated with the fund's investment strategy.

Government's Investor Class shares for each of the last 10 calendar years.

INFLATION-ADJUSTED TREASURY FUND
1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?
Inflation-Adjusted Treasury seeks total return and inflation protection
consistent with investment in U.S. Treasury inflation-adjusted securities.
2. WHAT IS THE FUND'S INVESTMENT STRATEGY?
The fund managers buy inflation-indexed U.S. Treasury securities guaranteed
primarily by the direct full faith and credit pledge of the U.S. government.
These inflation-indexed securities are designed to protect the future
purchasing power of the money invested in them.
The fund managers also may buy traditional U.S. Treasury securities that are
not inflation-indexed. The fund managers also may buy inflation-indexed
securities issued by U.S. government agencies and government-sponsored
organizations.
The fund managers may purchase securities in a number of different ways to
seek higher rates of return. For example, by using when-issued and forward
commitment transactions, the fund managers may purchase securities in
advance to generate additional income.
Additional information about Inflation-Adjusted Treasury'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?
* Inflation-indexed securities are designed to offer a return linked to
inflation, which protects future purchasing power from the effects of
inflation. Inflation-indexed securities may not trade at their face value.
Inflation-indexed securities trade at prevailing real, or after inflation,
interest rates. Changes in real interest rates affect the fund's share
value.
* As with all funds, your shares may be worth more or less at any given time
than the price you paid for them. If you sell your shares when the value is
less than the price you paid, you will lose money.
* 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, Inflation-Adjusted Treasury is intended for investors who seek
total return that is consistent with investment in U.S. Treasury
inflation-indexed securities and who are willing to accept the risks
associated with the fund's investment strategy.

You may sell all or part of your fund shares on any business day by writing

Treasury for shares in nearly 70 other mutual funds offered by American
Century. Depending on the options you select when you open your account,
some restrictions may apply. For your protection, some redemption requests
require a signature guarantee.
8. HOW ARE FUND DISTRIBUTIONS MADE AND TAXED?
Inflation-Adjusted Treasury pays distributions of substantially all of its
income, including "imputed income," monthly. Distributions may be taxable as
ordinary income, capital gains or a combination of the two. Capital gains
are taxed at different rates depending on the length of time the fund held
the securities that were sold. Distributions are reinvested automatically in
additional shares unless you choose another option.
Distributions will generally be exempt from most state income taxes. Consult
your tax advisor to see if the fund's income is exempt in your state.

Information contained in the services guide pertains to shareholders who

employer-sponsored retirement plan or financial intermediary, your ability
to purchase shares of the fund, exchange them for shares of other American
Century funds and redeem them will depend on the terms of your plan or
financial intermediary. If you have questions about investing in an
employer-sponsored retirement plan or through a financial intermediary, call
a Service Representative at 1-800-345-3533.
