Y2K TESTING EFFORTS PAY DIVIDENDS IN PREPAREDNESS
- --------------------------------------------------------------------------------
Y2K, short for the Year 2000, refers more specifically to the date change from
December 31, 1999 to January 1, 2000. This date change is significant for
computers because many were originally programmed to process dates with
two-character years--99 instead of 1999.
When the calendar rolls to 2000, this can create problems for computers
programmed this way because they will read the date as "00," and may interpret
it as 1900. Most companies have been working to reprogram their computer systems
with four-digit years. Reprogramming is very labor-intensive and requires
testing to ensure that there are no errors and that all lines of code were
successfully changed.
Recognizing the possible impact of the Y2K issue, our senior-level Steering
Committee, programmers, business partners and Y2K team have been working
diligently to make January 1, 2000 a non-event for American Century investors.
Currently, our systems have been modified, tested and returned to production,
and we have tested our systems with our vendors and business partners.
In March and April of this year, we participated in the Security Industry
Association's (SIA) industry-wide test and successfully processed transactions
for dates up to and beyond 2000. American Century transactions with our partner
firms were processed free of Y2K bugs. We also participated in the Market Data
Test conducted by the SIA and Financial Information Forum in May. Again, the
computer scripts were executed successfully with no Y2K-related errors.
In addition, our Y2K team has developed contingency plans. These plans are
designed to minimize the impact on our investors and help us maintain operations
in the event of any Y2K-related incidents. We have conducted practice drills of
contingency scenarios and will continue to refine our plans during the rest of
1999 to respond quickly and effectively so that the date change is as seamless
as possible for investors. We expect the Year 2000 to be business as usual at
American Century.

Strong economic growth and increasing inflation anxiety resulted in higher
money market yields during the six months ended August 31, 1999. The recovery of
overseas economies and unabated U.S. growth led the Federal Reserve (the U.S.
central bank) to raise short-term interest rates twice during the summer of
1999.
In this environment, Prime Money Market continued to shine, providing
above-average yields and returns. Fund investors have benefited from our
commitment to build and maintain a talented fund management group. American
Century's entire investment management team has doubled in size over the past
three years.
In addition to strengthening our portfolio and research staff, we've
recently made strategic investments in several other financial companies,
including Archipelago, Tradepoint Financial Networks, W.R. Hambrecht, and
WorldStreet Corporation. These investments demonstrate our determination to
actively support the development and use of technologies that improve the
efficiencies of capital markets, lower trading costs, and ultimately offer
better returns for shareholders.
Our commitment to delivering superior service to investors is reflected in
our redesigned quarterly statements, which have garnered some noteworthy
attention recently. American Century is the first mutual fund company to receive
the Communications Seal for a mutual fund statement from DALBAR Inc., an
independent mutual fund research firm. The seal recognizes communications
excellence that is exceptional for the industry and commends American Century
for meeting its customers' needs in an attractive, easy-to-read document.
This isn't American Century's first nod of approval from DALBAR. In June,
DALBAR recognized our statement's individual rate of return feature--part of the
personalized performance section--as the key reason it ranked our statement
second out of 88 mutual fund company statements in the nation.
One final note--in the spirit of our ongoing Year 2000 readiness
disclosures, we've provided a complete update on our preparations for Y2K on the
inside front cover of this report. We understand that our continued diligence in
this area is very important to you.
As always, we appreciate your continued confidence in American Century.
Sincerely,
/s/James E. Stowers, Jr. /s/James E. Stowers III

Money Market Funds--Frequently Asked Questions
- --------------------------------------------------------------------------------
[left margin]
A FASTER AND EASIER WAY TO DEPOSIT MUTUAL FUND DISTRIBUTIONS
If you prefer to have your fund dividend or capital gains distributions sent to
you instead of reinvesting them, there are a couple of ways to get access to
this money faster than waiting for a check in the mail:
* YOU CAN HAVE DISTRIBUTIONS DEPOSITED DIRECTLY INTO YOUR MONEY MARKET
ACCOUNT. The money will be deposited the same day that the distributions
are paid.
* DISTRIBUTIONS CAN BE SENT ELECTRONICALLY TO YOUR BANK ACCOUNT. The money
will be available in your bank account within three days.
Contact our Investor Relations Representatives to set up either of these
options.
CAN I MAKE DIRECT DEPOSITS INTO MY MONEY MARKET FUND ACCOUNT?
Yes. You can arrange for direct deposit of your paycheck, Social Security
check, Treasury Direct interest payment, military allotment, or payments from
other government agencies. Give us a call, and we will send you the necessary
information to set it up.
WHAT IS THE HOLDING PERIOD ON NEW DEPOSITS INTO MY ACCOUNT?
Generally, there is an eight-business-day holding period for deposited
funds (initial investments in a new account are held for 15 calendar days).
There is a one-business-day holding period for U.S. Treasury checks, money
orders, and travelers' checks.
IS THERE A LIMIT ON THE NUMBER OF CHECKS I CAN WRITE ON MY MONEY MARKET ACCOUNT?
No. You can write as many checks as you like at no charge, as long as each
check is for $100 or more.
IS THERE AN EASY WAY TO MOVE MONEY FROM MY MONEY MARKET FUND INTO A STOCK OR
BOND FUND?
Yes. Moving money between funds is called an exchange, and there is no
limit on the number of exchanges you can make out of a money market fund
account. However, there is a limit of six exchanges per calendar year out of
stock and bond fund accounts.
Exchanges can be made by:
* visiting our Web site at
www.americancentury.com*
* using our Automated Information Line (1-800-345-8765)*
* calling an Investor Relations Representative at 1-800-345-2021*
* writing us a letter
HOW DO I DECIDE WHETHER A TAXABLE MONEY MARKET FUND OR A TAX-FREE MONEY MARKET
FUND IS RIGHT FOR ME?
The most important factor to consider is your tax bracket. Tax-free money
market funds typically offer lower yields than taxable funds, but you pay no
federal income taxes on the income from a tax-free fund.
If you are in one of the higher federal income tax brackets, taxes will eat
up a big part of your income from a taxable money market fund, so a tax-free
investment may be better for you. If you're in a lower tax bracket, then you can
usually earn more in a taxable fund even after taxes are deducted.
We can help you figure it out. If you give us a call and tell us what tax
bracket you're in, we can tell you whether you're likely to earn more after-tax
income in a tax-free or a taxable money market fund.
IF YOU HAVE ANY QUESTIONS ABOUT OUR MONEY MARKET FUNDS, CALL US TOLL FREE AT
1-800-345-2021 OR E-MAIL US AT OUR WEB SITE, WWW.AMERICANCENTURY.COM.
* Before you can make an exchange by calling an Investor Relations
Representative, using our Automated Information Line, or visiting our Web
site, you first must have provided us with written authorization to do so.

Prime Money Market--Q&A
- --------------------------------------------------------------------------------
[photo of Denise Tabacco]
An interview with Denise Tabacco, portfolio manager on the Prime Money
Market fund investment team.
HOW DID PRIME MONEY MARKET PERFORM DURING THE SIX MONTHS ENDED AUGUST 31, 1999?
The fund's six-month return* ranked in the top quarter of the 347 "Money
Market Funds" tracked by Lipper Inc. Prime Money Market's longer-term returns
are equally strong. (See the previous page for fund returns and performance
comparisons.)
WHY DID THE FUND'S SEVEN-DAY CURRENT YIELD INCREASE DURING THE PERIOD (FROM
4.49% TO 4.70%)?
The Federal Reserve raised short-term interest rates twice in the past six
months--once at the end of June and again in late August. These rate hikes
pushed the federal funds rate target (an influential overnight lending rate for
banks) from 4.75% to 5.25%. When the Fed adjusts this rate target, money market
yields typically follow suit.
The two rate increases were a reversal of the rate cuts the Fed made in the
fall of 1998 to stabilize the markets during a period of global economic
turmoil. Since that time, foreign economies and markets have improved, so the
financial strain from overseas has become less of a concern.
HOW DID YOU POSITION THE FUND IN THIS ENVIRONMENT?
Back in March, we felt that the Fed was on hold and wouldn't raise interest
rates until it saw more definitive evidence of economic strength. As a result,
we maintained a longer weighted average maturity of around 80 days.
Stronger economic data in the second quarter and a surge in April's
consumer price index led us to change our expectations, so we shortened Prime
Money Market's average maturity gradually throughout June. A shorter average
maturity allows the fund to more quickly reflect higher interest rates.
By the end of June, the fund's average maturity was down to 70 days, and
for the most part we kept it right around there through the end of August.
PRIME MONEY MARKET'S HOLDINGS OF CDS HAVE INCREASED QUITE A BIT OVER THE PAST
YEAR. WHAT'S THE ATTRACTION?
From time to time, CDs offer significantly better yields than commercial
paper and other potential fund investments. This happens because the dealers
that sell CDs enhance the interest rate paid by the issuing banks. It's a
marketing gimmick, kind of like the occasional sale at a department store.
We've taken advantage of these opportunities over the past year to add more
CDs to the portfolio. That's had a positive impact on the fund's yield.

Prime Money Market--Q&A
- --------------------------------------------------------------------------------
(Continued)
WERE THERE ANY CREDIT QUALITY ISSUES OVER THE PAST SIX MONTHS?
The overall credit quality of the fund didn't really change, but one issuer
whose securities were held by the fund did suffer liquidity problems.
General American Life Insurance, an issuer of short-term investment
contracts, had difficulty making timely principal payments. The company ran into
trouble when many of its institutional investors--including us--asked for early
repayment of their investment after the insurer's credit rating was downgraded.
The situation was resolved in a matter of weeks. Metropolitan Life
Insurance acquired General American and assumed repayment responsibility. Prime
Money Market's investment, which represented 3% of the portfolio, was returned
on October 1, 1999.
The event had no effect on the fund's yield or share price.
LOOKING AHEAD, WHAT'S YOUR OUTLOOK FOR SHORT-TERM INTEREST RATES?
We don't see any clear-cut reasons for the Fed to raise interest rates
further, so we expect short-term rates to be relatively stable in the coming
months.
Inflation, as measured by the consumer price index, has risen at a slightly
faster rate than in 1998--mainly because of surging oil prices--but it remains
historically low. In addition, economic activity in areas like construction and
home sales has shown signs of a slowdown.
That said, there is certainly no guarantee that the Fed is out of the
picture, so we'll be carefully monitoring the situation over the next few
months.
WHAT ARE YOUR PLANS FOR PRIME MONEY MARKET GOING FORWARD?
Right now, securities maturing in four to six months are offering
substantially higher yields than three-month securities. We recently purchased
more securities in this maturity sector to take advantage of their higher
yields, and we offset these holdings with very short-term securities to maintain
an average maturity of 70-80 days. We expect to keep the average maturity in
this range for the time being.

"WE DON'T SEE ANY CLEAR-CUT REASONS FOR THE FED TO RAISE INTEREST RATES FURTHER,
SO WE EXPECT SHORT-TERM RATES TO BE RELATIVELY STABLE IN THE COMING MONTHS."

This statement breaks down the fund's ASSETS (such as securities, cash, and
other receivables) and LIABILITIES (money owed for securities purchased,
management fees and other liabilities) as of the last day of the reporting

ASSETS. For each class of shares, the net assets divided by shares outstanding
is the share price, or NET ASSET VALUE PER SHARE. This statement also breaks
down the fund's net assets into capital (shareholder investments) and
performance (investment income and gains/losses).

AUGUST 31, 1999 (UNAUDITED)
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
ORGANIZATION -- American Century Investment Trust (the trust) is registered
under the Investment Company Act of 1940 as an open-end management investment
company. Prime Money Market Fund (the fund) is the only fund issued by the
trust. The fund seeks the highest level of current income consistent with
preservation of capital. The fund buys high quality (first tier), U.S. dollar
denominated money market instruments and other short-term obligations of banks,
governments, and corporations. The fund is authorized to issue two classes of
shares: the Investor Class and the Advisor Class. The two classes of shares
differ principally in their respective shareholder servicing and distribution
expenses and arrangements. All shares of the fund represent an equal pro rata
interest in the assets of the class to which such shares belong, and have
identical voting, dividend, liquidation and other rights and the same terms and
conditions, except for class specific expenses and exclusive rights to vote on
matters affecting only individual classes. The following significant accounting
policies are in accordance with generally accepted accounting principles; these
principles may require the use of estimates by fund management.
SECURITY VALUATIONS -- Securities are valued at amortized cost, which
approximates current market value. When valuations are not readily available,
securities are valued at fair value as determined in accordance with procedures
adopted by the Board of Trustees.
SECURITY TRANSACTIONS -- Security transactions are accounted for as of the
trade date. Net realized gains and losses are determined on the identified cost
basis, which is also used for federal income tax purposes.
INVESTMENT INCOME -- Interest income is recorded on the accrual basis and
includes accretion of discounts and amortization of premiums. Discounts and
premiums are accreted/amortized daily on a straight-line basis.
INCOME TAX STATUS -- It is the fund's policy to distribute all taxable
income and to otherwise qualify as a regulated investment company under the
provisions of the Internal Revenue Code. Accordingly, no provision has been made
for federal or state income taxes.
DISTRIBUTIONS -- Distributions from net investment income are declared and
credited daily and distributed monthly. The fund does not expect to realize any
long-term capital gains, and accordingly, does not expect to pay any capital
gains distributions.
At February 28, 1999, the fund had accumulated net realized capital loss
carryovers of $356,686 (expiring 2001 through 2007) which may be used to offset
future taxable gains.
ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is the trust's
distributor. Certain officers of FDI are also officers of the trust.
- --------------------------------------------------------------------------------
2. TRANSACTIONS WITH RELATED PARTIES
The trust has entered into a Management Agreement with American Century
Investment Management, Inc. (ACIM), under which ACIM provides the fund with
investment advisory and management services in exchange for a single, unified
management fee per class. The Agreement provides that all expenses of the fund,
except brokerage, taxes, portfolio insurance, interest, fees and expenses of the
Trustees who are not considered "interested persons" as defined in the
Investment Company Act of 1940 (including counsel fees) and extraordinary
expenses, will be paid by ACIM. The fee is calculated daily and paid monthly. It
consists of an Investment Category Fee based on the average net assets of the
funds in a specific fund's investment category and a Complex Fee based on the
average net assets of all the funds managed by ACIM. The rates for the
Investment Category Fee range from 0.2570% to 0.3700% and the rates for the
Complex Fee (Investor Class) range from 0.2900% to 0.3100%. The Advisor Class is
0.2500% less at each point within the Complex Fee range. For the six months
ended August 31, 1999, the effective annual Investor Class management fee was
0.60%.
The Board of Trustees has adopted the Advisor Class Master Distribution and
Shareholder Services Plan (the plan), pursuant to Rule 12b-1 of the Investment
Company Act of 1940. The plan provides that the fund will pay ACIM an annual
distribution fee equal to 0.25% and annual service fee equal to 0.25%. The fees
are computed daily and paid monthly based on the Advisor Class's average daily
closing net assets during the previous month. The distribution fee provides
compensation for distribution expenses incurred by financial intermediaries in
connection with distributing shares of the Advisor Class including, but not
limited to, payments to brokers, dealers, and financial institutions that have
entered into sales agreements with respect to shares of the fund. The service
fee provides compensation for shareholder and administrative services rendered
by ACIM, its affiliates or independent third party providers. Fees incurred
under the plan during the six months ended August 31, 1999 were $9,150.
Certain officers and Trustees of the trust are also officers and/or
directors, and, as a group, controlling stockholders of American Century
Companies, Inc., the parent of the trust's investment manager, ACIM, and the
trust's transfer agent, American Century Services Corporation.
On August 23, 1999, the fund and American Century Companies (ACC) entered
into an agreement allowing the fund to sell to ACC or ACC to acquire from the
fund the General American Life Insurance Company security (the security), at
par, at each parties discretion. On September 15, 1999, Metropolitan Life
Insurance Company (MetLife) acquired General American Life Insurance. Upon
recommendation from the Board of Trustees, the fund entered into an agreement
with MetLife in which the security was exchanged for substantially similar
securities issued by MetLife. Full payment of all principal plus accrued
interest through September 30, 1999, was received by the fund from MetLife on
October 1, 1999.

SHARE CLASSES
Two classes of shares are authorized for sale by the fund: Investor Class
and Advisor Class.
INVESTOR CLASS shareholders do not pay any commissions or other fees for
purchase of fund shares directly from American Century. Investors who buy
Investor Class shares through a broker-dealer may be required to pay the
broker-dealer a transaction fee.
ADVISOR CLASS shares are sold through banks, broker-dealers, insurance
companies and financial advisors. Advisor Class shares are subject to a 0.50%
Rule 12b-1 service and distribution fee. Half of that fee is available to pay
for recordkeeping and administrative services, and half is available to pay for
distribution services provided by the financial intermediary through which the
Advisor Class shares are purchased. The total expense ratio of the Advisor Class
shares is 0.25% higher than the total expense ratio of the Investor Class
shares.
Both classes of shares represent a pro rata interest in the funds and
generally have the same rights and preferences.
RETIREMENT ACCOUNT INFORMATION
As required by law, any distributions you receive from an IRA and certain
403(b) distributions [not eligible for rollover to an IRA or to another 403(b)
account] are subject to federal income tax withholding at the rate of 10% of the
total amount withdrawn, unless you elect not to have withholding apply. If you
don't want us to withhold on this amount, you may send us a written notice not
to have the federal income tax withheld. Your written notice is valid from the
date of receipt at American Century. Even if you plan to roll over the amount
you withdraw to another tax-deferred account, the withholding rate still applies
to the withdrawn amount unless we have received a written notice not to withhold
federal income prior to the withdrawal.
When you plan to withdraw, you may make your election by completing our
Exchange/Redemption form or an IRS Form W-4P. Call American Century for either
form. Your written election is valid from the date of receipt at American
Century. You may revoke your election at any time by sending a written notice to
us.
Remember, even if you elect not to have income tax withheld, you are liable
for paying income tax on the taxable portion of your withdrawal. If you elect
not to have income tax withheld or you don't have enough income tax withheld,
you may be responsible for payment of estimated tax. You may incur penalties
under the estimated tax rules if your withholding and estimated tax payments are
not sufficient.

Background Information
- --------------------------------------------------------------------------------
INVESTMENT PHILOSOPHY AND POLICIES
American Century offers 38 fixed-income funds, ranging from money market
funds to long-term bond funds and including both taxable and tax-exempt funds.
Each fund is managed to provide a "pure play" on a specific sector of the
fixed-income market.
To ensure adherence to this principle, the basic structure of each fund's
portfolio is tied to a specific market index. Fund managers attempt to add value
by making modest portfolio adjustments based on their analysis of prevailing
market conditions.
Investment decisions are made by management teams, which meet regularly to
discuss market analysis and investment strategies.
In addition to these principles, each fund has its own investment policies
PRIME MONEY MARKET seeks to provide interest income by investing in a
diversified portfolio of short-term money market securities. The fund must
maintain a weighted average maturity of 90 days or less.
An investment in Prime Money Market is neither insured nor guaranteed by
the FDIC or any other government agency. Yields will fluctuate, and although the
fund seeks to preserve the value of your investment at $1 per share, it is
possible to lose money by investing in the fund.
COMPARATIVE INDICES
The following index is used in the report for fund performance comparisons.
It is not an investment product available for purchase.
The 90-DAY TREASURY BILL INDEX is derived from secondary market interest
rates as published by the Federal Reserve Bank.
LIPPER RANKINGS
LIPPER INC. is an independent mutual fund ranking service that groups funds
according to their investment objectives. Rankings are based on average annual
returns for each fund in a given category for the periods indicated. Rankings
are not included for periods less than one year.
The funds in Lipper's MONEY MARKET INSTRUMENT FUNDS category intend to
maintain a stable net asset value and invest in high-quality financial
instruments rated in the top two grades with dollar-weighted average maturities
of less than 90 days.
CREDIT RATING GUIDELINES
Credit ratings are issued by independent research companies such as
Standard & Poor's and Moody's. They are based on an issuer's financial strength
and ability to pay interest and principal in a timely manner.
A-1 (which includes A-1+) is Standard & Poor's highest credit rating for
short-term securities. Here are the most common short-term credit ratings and
their definitions:
* A-1+: extremely strong ability to meet financial obligations.
* A-1: strong ability to meet financial obligations.
* A-2: satisfactory ability to meet financial obligations.
It's important to note that credit ratings are subjective, reflecting the
opinions of the rating agencies; they are not absolute standards of quality.

Glossary
- --------------------------------------------------------------------------------
RETURNS
* TOTAL RETURN figures show the overall percentage change in the value of a
hypothetical investment in the fund and assume that all of the fund's
distributions are reinvested.
* AVERAGE ANNUAL RETURNS illustrate the annually compounded returns that would
have produced the fund's cumulative total returns if the fund's performance had
been constant over the entire period. Average annual returns smooth out
variations in a fund's return; they are not the same as fiscal year-by-year
results. For fiscal year-by-year returns, please refer to the "Financial
Highlights" on pages 15-16.
YIELDS
* 7-DAY CURRENT YIELD is calculated based on the income generated by an
investment in the fund over a seven-day period and is expressed as an annual
percentage rate.
* 7-DAY EFFECTIVE YIELD is calculated similarly, although this figure is
slightly higher than the fund's 7-Day Current Yield because of the effects of
compounding. The 7-Day Effective Yield assumes that income earned from the
fund's investments is reinvested and generating additional income.
PORTFOLIO STATISTICS
* NUMBER OF ISSUERS -- the number of entities that issued securities held by the
fund on a given date.
* WEIGHTED AVERAGE MATURITY (WAM) -- a measure of the sensitivity of a
fixed-income portfolio to interest rate changes. WAM indicates the average time
until the securities in the portfolio mature, weighted by dollar amount. The
longer the WAM, the more interest rate exposure and sensitivity the portfolio
has.
* EXPENSE RATIO -- the operating expenses of the fund, expressed as a percentage
of average net assets. Shareholders pay an annual fee to the investment manager
for investment advisory and management services. The expenses and fees are
deducted from fund income, not from each shareholder account. (See Note 2 in the
Notes to Financial Statements.)
TYPES OF MONEY MARKET SECURITIES
* ASSET-BACKED SECURITIES -- debt securities that represent ownership in a pool
of receivables, such as credit card debt, auto loans, or mortgages.
* CERTIFICATES OF DEPOSIT (CDS) -- CDs represent a bank's obligation to repay
money deposited with it for a specified period of time. Different types of CDs
have different issuers. For example, Yankee CDs are issued by U.S. branches of
foreign banks, and Eurodollar CDs are issued in London by Canadian, European,
and Japanese banks.
* COMMERCIAL PAPER (CP) -- short-term debt issued by large corporations to raise
cash and to cover current expenses in anticipation of future revenues. The
maximum maturity for CP is 270 days, although most CP is issued in a one- to
50-day maturity range. CP rates generally track those of other widely traded
money market instruments, such as Treasury bills and certificates of deposit,
but they are also influenced by the maturity date and the size and credit rating
of the issuer.
* VARIABLE-RATE NOTES (VRNS) -- debt securities whose interest rates change when
a designated base rate changes. The base rate is often the federal funds rate,
the 90-day Treasury bill rate, or the London Interbank Offered Rate (LIBOR).
VRNs are considered derivatives because they "derive" their interest rates from
their designated base rates. However, VRNs are not "risky" derivatives--their
behavior is similar to that of their designated base rates. The SEC has
recognized this similarity and does not consider VRNs to be inappropriate
investments for money market funds.
* U.S. GOVERNMENT AGENCY SECURITIES -- debt securities issued by U.S. government
agencies (such as the Federal Farm Credit Bank and the Federal Home Loan Bank).
Some agency securities are backed by the full faith and credit of the U.S.
government, while most are guaranteed only by the issuing agency. These
securities are issued with maturities ranging from three months to 30 years.
Money market funds invest in these securities when they have remaining
maturities of 13 months or less.

FUND CLASSIFICATIONS
INVESTMENT OBJECTIVE
The investment objective may be based on the fund's objective as stated in
its prospectus or fund profile, or the fund's categorization by independent
rating organizations based on its management style.
* CAPITAL PRESERVATION -- offers taxable and tax-free money market funds for
relative stability of principal and liquidity.
* INCOME -- offers funds that can provide current income and competitive yields,
as well as a strong and stable foundation and generally lower volatility levels
than stock funds.
* GROWTH & INCOME -- offers funds that emphasize both growth and income provided
by either dividend-paying equities or a combination of equity and fixed-income
securities.
* GROWTH -- offers funds with a focus on capital appreciation and long-term
growth, generally providing high return potential with corresponding high price
fluctuation risk.
RISK
The classification of funds by risk category is based on quantitative
historical measures as well as qualitative prospective measures. It is not
intended to be a precise indicator of future risk or return levels. The degree
of risk within each category can vary significantly, and some fund returns have
historically been higher than more aggressive funds or lower than more
conservative funds. Please be aware that the fund's category may change over
time. Therefore, it is important that you read a fund's prospectus or fund
profile carefully before investing to ensure its objectives, policies and risk
potential are consistent with your needs.
* CONSERVATIVE -- these funds generally provide lower return potential with
either low or minimal price fluctuation risk.
* MODERATE -- these funds generally provide moderate return potential with
moderate price fluctuation risk.
* AGGRESSIVE -- these funds generally provide high return potential with
corresponding high price fluctuation risk.

* While listed within the Income investment objective, the Target funds do not
pay current dividend income. Income dividends are distributed once a year in
December. The Target funds are listed in all three risk categories due to the
dramatic price volatility investors may experience during certain market
conditions. If held to their target dates, however, they can offer a
conservative, dependable way to invest for a specific time horizon.
