                               REPORT HIGHLIGHTS

PERIOD OVERVIEW

o    The U.S.  economy  expanded rapidly during the twelve months ended February
     28, 1997. The economy grew much faster than expected,  particularly  during
     the second and fourth quarters of 1996.

o    Signs of continued  economic  strength have many  predicting  first-quarter
     1997 economic growth to be between 3.0% and 3.5%.

o    Despite the rapid  expansion of the economy,  inflation  remained tame. For
     all of 1996, core consumer  prices--which  exclude  often-volatile food and
     energy prices--rose by just 2.6%, tying 1994 for the lowest annual increase
     in almost 30 years.

o    The seemingly contradictory  combination of strong growth and low inflation
     caused considerable uncertainty in U.S. financial markets about the Federal
     Reserve's interest rate intentions.

o    This  uncertainty  caused money market  rates to fluctuate  throughout  the
     period.

CORPORATE CREDIT REVIEW

o    A strong  U.S.  economy  led to  improved  corporate  credit  during  1996.
     According  to  bond-rater  Moody's  Investors  Service,   corporate  credit
     upgrades outpaced downgrades by 283 to 184 during 1996.

o    Despite the generally positive credit outlook, "sub-prime" auto lenders--so
     called   because   they  make   loans  to   borrowers   with  poor   credit
     histories--defaulted on debt payments or suffered credit rating downgrades.

o    Japanese banks  continued to suffer from slow economic  growth and slumping
     Japanese real estate and stock  markets.  We expect many Japanese  banks to
     report significant losses when the Japanese fiscal year ends on March 31.

MANAGEMENT Q&A

o    The fund  returned  5.04% for the twelve  months  ended  February 28, 1997,
     compared  with  the  4.76%  average  return  of  its  peer  group.  Prime's
     life-of-fund  return  places  it in the top 5% of its  peer  group  average
     (according to Lipper Analytical Services).

o    With yields remaining in a narrow range throughout the period,  our steady,
     conservative approach to managing the fund's average maturity paid off with
     above-average return.

o    Some money market funds were hit by defaults and  downgrades on debt issued
     by sub-prime  auto lenders,  but Prime was  unaffected  because these risky
     issuers failed to meet our strict credit criteria.

o    We  enhanced  the  fund's  responsiveness  to  changing  interest  rates by
     increasing its holdings of floating-rate  notes, whose interest rates reset
     periodically.

o    Going  forward,  we  expect  strong  economic  growth  and  low  levels  of
     unemployment  to push interest rates higher.  We'll try to capture the rise
     in rates by keeping the fund's  average  maturity at the low end of its 50-
     to 60-day neutral range.

                               OUR MESSAGE TO YOU

[photo of James E. Stowers III and James M. Benham]

The fiscal year ended  February 28,  1997,  was an eventful  one,  both for U.S.
money market rates and our company.  Over the past twelve  months,  money market
rates  fluctuated  in response to changing  interest rate  expectations.  In the
following pages,  our investment  management team provides further details about
the market and how your fund was managed during the year.

Fluctuating market conditions  underscore the importance of quality investments.
Our commitment to high-quality securities is exemplified by the expansion of our
credit research team. The seven members of the team perform an in-depth analysis
on all securities  considered for purchase by American  Century money market and
bond funds.  The team has  established a credit  management  system that defines
investment limits to cap our funds' exposure to individual issuers, countries or
industries.  The team plays an  important  role in the  management  of the Prime
Money Market Fund.

On the corporate  front, we completed the  operational  integration of Twentieth
Century and The Benham Group in September 1996. As a result, you now have direct
access to a broader spectrum of funds and services.

We also changed the name of our company.  On January 1, 1997,  we began  serving
you under the name American  Century  Investments,  which  reflects our expanded
identity and the independent  thinking  common to Twentieth  Century and Benham.
American  Century's fund family is divided into three groups--the  Benham Group,
the American  Century Group and the  Twentieth  Century  Group.  The Prime Money
Market  Fund will  remain in the Benham  Group,  because  the fund's  investment
goals--current income and the preservation of principal--match key attributes of
that group.

This report  incorporates a new format  designed  using your input.  We hope you
find it more informative and easier to read. Another informative resource is the
American  Century Web site.  If you use a personal  computer  and have  Internet
access,  we've made it easier for you to  download  information  about  American
Century funds and access your fund  accounts.  With a personal  access code, you
can view account  balances,  exchange money between  existing  accounts and make
additional investments. The Web site address is: www.americancentury.com. We are
one of the first fund  companies to offer direct  on-line  transactions  via the
Internet.

These  are  examples  of how we  continue  to work to  provide  information  and
services that are useful and convenient to investors in our funds. Thank you for
investing with us.

Sincerely,

/s/James E. Stowers III                       /s/James M. Benham

                                PERIOD OVERVIEW

U.S. Economy

The U.S.  economy  expanded  rapidly during the twelve months ended February 28,
1997.  Strong  employment growth and a booming housing market helped the economy
grow at a 4.7% annual rate during the second quarter of 1996.  While the pace of
growth slowed to 2.1% during the third quarter, the economy came roaring back in
the fourth quarter to expand at a 3.8% annual rate. Signs of continued  economic
strength have many predicting  first-quarter  1997 economic growth to be between
3.0% and 3.5%.

Despite the rapid expansion of the economy,  inflation remained tame in 1996 and
early 1997. Core consumer prices,  which exclude  often-volatile food and energy
prices,  rose by just 2.6% in 1996, tying 1994 for the lowest annual increase in
almost 30 years.  Though wages rose during the period,  overall labor costs were
kept in check by lower  healthcare  and benefit  costs.  A stronger  dollar also
helped keep inflation in check by making  imported goods less expensive for U.S.
consumers. With inflation dormant, the Federal Reserve (the Fed) held short-term
interest rates steady throughout the period.

Despite  the fact  that  inflation  remained  tame,  the Fed  raised  short-term
interest rates in March 1997 to pre-empt  higher  inflation.  While we think the
Fed may raise  interest  rates  further,  we don't expect the federal funds rate
(the  lending  rate  targeted  by the  Fed for  large  overnight  loans  between
commercial  banks) to breach the 6% level.  That's  because  the "real"  federal
funds rate--the federal funds rate minus the rate of inflation--is  already at a
level that would inhibit economic growth.

Corporate Money Market Securities

Changing  expectations  of Fed interest rate policy caused money market rates to
fluctuate  sharply between March 1996 and February 1997. At the beginning of the
period,  many  expected the U.S.  economy to wind down in 1996,  but a series of
stronger-than-expected  reports on the  economy  dispelled  that  notion  almost
immediately.  The seemingly contradictory  combination of strong economic growth
and low inflation was responsible for the markets'  uncertainty  about the Fed's
interest rate intentions.

The  accompanying  graph  depicts the  volatility  in money market rates between
March  1996 and  February  1997.  As the graph  illustrates,  three-month  LIBOR
(London  Interbank  Offered Rate),  which tends to reflect market  participants'
future  expectations for short-term  interest rates,  fluctuated  throughout the
period.  (LIBOR is a money  market rate that most banks and  corporations  track
when  determining  the rate they'll pay to investors  on  short-term  debt.) The
sharpest  movements in three-month  LIBOR typically  occurred in response to the
release of the government's  monthly employment report, which the market uses as
a gauge of U.S. economic strength.

Annual Report                                               Period Overview    3


CORPORATE CREDIT REVIEW

A strong U.S.  economy led to improved  corporate credit  conditions  during the
twelve  months  ended  February  28,  1997.  Steady  corporate  earnings  growth
contributed to a record number of corporate credit rating upgrades. According to
bond-rating  agency Moody's  Investors  Service,  upgrades  outpaced  downgrades
during 1996 by 283 to 184, a ratio of 3 to 2.

Specific  industries  benefiting  from the  upgrade  trend  included  industrial
companies,  most recently in the airline sector. In the financial sector,  banks
continued  a credit  upgrade  trend that  began a few years ago,  while a rising
stock market and heavy initial public offering activity translated into upgrades
for brokerage firms.

Nevertheless, we continue to monitor a few negative credit trends evident during
the period.  Two problem areas  highlight  how our  proactive  and  conservative
approach to credit analysis helps limit the fund's credit risk.

So far in 1997,  several  "sub-prime" auto lenders--so  called because they make
loans to borrowers with poor credit  histories--have  defaulted on debt payments
or experienced credit rating downgrades.

The difficulties experienced by sub-prime lenders (which struck some mutual fund
companies)  illustrate the importance of our conservative credit criteria.  Take
sub-prime  lender Mercury Finance,  which defaulted on its debt payments,  as an
example.  Mercury's direct debt issues were considered "tier 1" according to SEC
standards. The SEC defines a "tier 1" security as an issue that has received the
highest possible  short-term  rating from two independent  rating agencies.  Our
standards for  considering  a security for purchase are much tougher.  Mercury's
debt failed to clear even the first hurdle in our internal rating process.

Another  development  we're  watching  closely is the ongoing  Japanese  banking
crisis.  Japanese banks have suffered since 1990,  when  speculative  bubbles in
both the  Japanese  real  estate and stock  markets  burst.  Japan's  economy is
recovering  slowly,  while  its  real  estate  and  stock  markets  continue  to
deteriorate. We expect many Japanese banks to report significant losses from bad
real estate loans,  falling equity positions and sluggish loan activity when the
Japanese fiscal year ends March 31.

To prop up the banking system, the Japanese  government  announced it would back
the 20 largest  Japanese  banks.  We've pared down that list of 20 to only those
banks  that can  function  independently.  In  practice,  that means the list of
Japanese  banks with which we'll do business is much shorter than the list of 20
that others find acceptable. We currently have no Japanese bank exposure.

MANAGEMENT Q&A

An interview with Amy O'Donnell,  a portfolio  manager on the Prime Money Market
fund management team.

How did the fund perform?

The fund  performed  very well  relative to its peers  during the twelve  months
ended February 28, 1997. For the fiscal year, the fund returned 5.04%, exceeding
the 4.76% average return of the 291 "Money Market  Instrument  Funds" tracked by
Lipper.  The  fund's  longer-term  returns  are even  more  impressive:  Prime's
life-of-fund  return places it in the top 5% of its Lipper category.  The fund's
long-term  performance was aided by the fact that Benham Management  Corporation
waived its  management  fees and absorbed  the fund's  operating  expenses  from
inception  through  December  31,  1994.  (See the  Total  Returns  table on the
previous page for other fund performance comparisons.)

How was the fund positioned during the period?

With yields  remaining in a narrow range, we made only minor  adjustments to the
fund's  positioning.  Concern that the Fed might raise rates led us to bring the
fund's average  maturity near the low end of its neutral range of 50 to 60 days.
(The fund benefits from a shorter average maturity when rates are rising because
we can  reinvest  its assets  more  quickly.)  Rather  than try to  predict  the
direction of interest rates, we took a steady,  conservative  approach that paid
off with above-average return for the fund.

Some money market funds were recently affected by defaults and rating downgrades
on debt  issued  by some of the most  aggressive  auto  loan  companies,  called
"sub-prime  lenders." Did the fund hold any  securities  that  defaulted or were
downgraded?

No. The fund has never owned securities  issued by a sub-prime auto lender.  The
consistent,  disciplined  application of our conservative credit criteria is one
reason we weren't  affected by a default  that hit some of our  competitors.  We
simply don't want to increase our credit risk for a slightly  higher  yield.  We
rely on our high credit standards to narrow down the universe of issuers to what
we feel are the most creditworthy.  From that exclusive list, we do our homework
to uncover the best yield and return stories.

You increased the fund's holdings of floating-rate notes (floaters). Why?

Floaters  are a good way to  increase  the fund's  responsiveness  to changes in
interest   rates   because   their   coupons   reset   on  a   periodic--usually
monthly--basis. We buy floaters that reset off of the federal funds rate when we
think rates are going down. That's because fed funds is a lagging indicator that
reflects changes to rates only after the fact. When we think rates are going up,
which is our  current  expectation,  we buy  floaters  that reset off of 1-month
LIBOR.  LIBOR  floaters are  especially  attractive  in a rising  interest  rate
environment  because  LIBOR  tends  to  reflect  market   participants'   future
expectations for the level of interest rates.

6    Management Q&A                            American Century Investments


MANAGEMENT Q&A

You overweighted the fund's holdings in the industrial  sector and underweighted
the financial sector. Why?

About 75% of all short-term  corporate debt is issued by financial  institutions
(such as banks and insurance companies),  but the fund's holdings are just about
evenly divided between industrials and financials. We consider this an effective
way to enhance the fund's diversification. However, we're not buying industrials
simply for the sake of diversification; in general, financial companies are very
creditworthy  issuers,  but they can be somewhat volatile because their business
touches on so many sectors of the market.  One attraction of industrial paper is
that when we buy an issue, we're only exposed to a single sector.

Asset-backed  securities  are a large and growing  part of the  corporate  money
market. Do you plan to incorporate more asset-backed securities into the fund?

Yes.  Asset-backed  securities  have very high credit quality because they carry
credit enhancements,  such as bond insurance. Another attraction of asset-backed
securities is that they typically have higher yields than  commercial  paper and
CDs.  We'd be more likely to buy them when we want to extend the fund's  average
maturity because they tend to have one-year maturities. But before we go in this
direction,  we want to be sure we're doing it right, so we're adding specialists
in asset-backed securities to our corporate credit research staff.

What's your outlook for money market rates going forward?

It's  uncertain if the Fed's March 1997  interest  rate increase was an isolated
event or the first in a series of moves.  Nevertheless,  high levels of consumer
confidence,  a vibrant housing market and rising  employment and wage growth all
seem to argue for strong U.S.  economic growth.  As a result, we expect rates to
go even higher in the months ahead.

With  that  outlook  in mind,  how will you  manage  the fund  over the next six
months?

We'll likely shift the fund's  portfolio to a laddered  structure,  which should
perform  better in a rising  interest  rate  environment.  (A  ladder  structure
staggers  the  maturities  of the  fund's  securities  so they  occur at regular
intervals.) Because we don't think the Fed is going to raise rates aggressively,
we won't  shorten the fund's  maturity as much as we otherwise  might when rates
are rising.  We'll probably keep the fund's average  maturity at around 50 days.
That will allow us to buy more longer-maturity paper than we normally would in a
rising interest rate environment, which should help boost the fund's yield.

                         NOTES TO FINANCIAL STATEMENTS

FEBRUARY 28, 1997

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.
American  Century-Benham  Prime  Money  Market  Fund (the Fund) is the sole 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 following
significant  accounting  policies,  related to the Fund, are in accordance  with
accounting policies generally accepted in the investment company industry.

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 on the  date
purchased  or  sold.  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
amortization of discounts and premiums.

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
income taxes.

Distributions--Distributions  from net investment  income are declared 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, 1997,  accumulated  net realized  capital  loss  carryovers  of
$278,535 (expiring 2005) may be used to offset future taxable gains.

Supplementary  Information--Certain  officers and trustees of the Trust are also
officers and/or directors, and, as a group, controlling stockholders of American
Century  Companies,  Inc. (ACC), the parent of the Trust's  investment  advisor,
Benham Management  Corporation (BMC), the Trust's distributor,  American Century
Investment  Services,  Inc.  (ACIS),  and the Trust's  transfer agent,  American
Century Services Corporation (ACSC).

Use of  Estimates--The  preparation of financial  statements in conformity  with
generally accepted  accounting  principles requires management to make estimates
and assumptions  that affect the reported  amounts of assets and liabilities and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the reported  amounts of increases  and  decreases in net assets
from  operations  during the  period.  Actual  results  could  differ from these
estimates.

Organization   Cost--Costs   incurred  by  the  Fund  in  connection   with  its
organization,  initial  registration,  and public  offering  of shares are being
amortized on a straight-line basis over a five-year period ending October 1998.

                         NOTES TO FINANCIAL STATEMENTS

FEBRUARY 28, 1997

- ------------------------------------------------------------------------
2. Transactions with Related Parties

The  Trust has  entered  into an  Investment  Advisory  Agreement  with BMC that
provides  the  Trust  with  investment  advisory  services  in  exchange  for an
investment  advisory  fee.  ACSC pays all  compensation  of Trust  officers  and
trustees who are officers or  directors  of ACC or any of its  subsidiaries.  In
addition,  promotion and  distribution  expenses are paid by BMC. The investment
advisory fee is paid monthly by the Fund by applying its average  daily  closing
net assets to the following annualized investment advisory fee schedule:

          0.50% of the first $100 million 
          0.45% of the next $100 million 
          0.40% of the next $100 million  
          0.35% of the next $100 million 
          0.30% of the next $100 million  
          0.25% of the next $1 billion 
          0.24% of the next $1 billion
          0.23% of the next $1 billion  
          0.22% of the next $1 billion 
          0.21% of the next $1 billion 
          0.20% of the next $1 billion
          0.19% of the average daily net assets over $6.5 billion

The Trust has an  Administrative  Services and Transfer  Agency  Agreement  with
ACSC. Under the Agreement,  ACSC provides  substantially all  administrative and
transfer agency services  necessary to operate the Fund. Fees for these services
are based on  transaction  volume,  number of accounts and average daily closing
net assets for funds  advised by BMC. The  Agreement  was  formerly  with Benham
Financial Services, Inc.

The Trust has an additional agreement with BMC pursuant to which BMC established
a contractual  expense guarantee that limits Fund expenses (excluding items such
as brokerage  commissions,  taxes, interest, and custodian earnings credits, and
extraordinary  expenses)  to 0.50% of average  daily  closing  net  assets.  The
agreement provides that BMC may recover amounts (representing expenses in excess
of the Fund's expense  guarantee  rate) absorbed during the preceding 11 months,
if, and to the extent that,  for any given month,  the Fund's  expenses are less
than the expense  guarantee rate in effect at that time.  The expense  guarantee
rate is in effect through May 31, 1998.

The payable to affiliates as of February 28, 1997, based on the above agreements
were as follows:

Investment Advisor ................ $177,390
Administrative Services and
Transfer Agent ....................  276,355
                                    --------
                                    $453,745
                                    ========


- ------------------------------------------------------------------------
3. Expense Offset Arrangements

The Fund's Statement of Operations  reflect custodian  earnings  credits.  These
amounts  are  used to  offset  the  custodian  fees  payable  by the Fund to the
custodian  bank.  The credits  are earned  when the Fund  maintains a balance of
uninvested  cash at the custodian  bank.  Beginning with the year ended February
29, 1996,  the ratios of  operating  expenses to average net assets shown in the
Financial Highlights are calculated as if these credits had not been earned.

                          INDEPENDENT AUDITORS' REPORT

The Board of Trustees and Shareholders
American Century Investment Trust:

We have audited the accompanying statement of assets and liabilities,  including
the schedule of investment  securities,  of American  Century-Benham Prime Money
Market Fund (a series of American Century  Investment  Trust) as of February 28,
1997,  and the related  statement  of  operations  for the year then ended,  the
statements of changes in net assets for each of the years in the two-year period
then ended,  and the  financial  highlights  for each of the periods  presented.
These financial  statements and financial  highlights are the  responsibility of
the  Fund's  management.  Our  responsibility  is to express an opinion on these
financial statements and financial highlights based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our  procedures  included  confirmation  of securities  owned as of
February 28, 1997, by  correspondence  with the custodian and brokers.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

In our opinion,  the financial  statements and financial  highlights referred to
above  present  fairly,  in all material  respects,  the  financial  position of
American  Century-Benham  Prime Money Market Fund (a series of American  Century
Investment  Trust) as of February 28, 1997, the results of its  operations,  the
changes in its net assets and the financial highlights for the periods indicated
above, in conformity with generally accepted accounting principles.

                              IMPORTANT NOTICE FOR
                        ALL IRA AND 403(b) SHAREHOLDERS

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)] 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 for six months 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 tax within six months 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  for only six  months  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 & Policies

American Century  Investments offers 42 fixed-income  funds,  ranging from money
market funds to long-term  bond funds and including  both taxable and tax-exempt
funds.

Prime Money  Market  seeks as high a level of interest  income as is  consistent
with the  preservation  of principal 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
U.S. government.  Yields will fluctuate,  and there can be no assurance that the
fund will be able to maintain a stable net asset value of $1 per share.

Comparative Indices

The following index is used in the report as a fund performance  comparison.  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 Analytical  Services,  Inc. is an independent mutual fund ranking service
that groups funds according to their investment  objectives.  Rankings are based

Money Market Instrument  Funds--funds that intend to maintain a stable net asset
value and that invest in high-quality financial instruments rated in the top two
grades with dollar-weighted average maturities of less than 90 days.

GLOSSARY

Returns

o    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.

o    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 page 16.

Yields

o    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.

o    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

o    Number of Issues--the  number of different  securities  held by a fund on a
     given date.

o    Weighted  Average  Maturity  (WAM)--a  measurement 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.

o    Expense  Ratio--the   operating  expenses  of  the  fund,  expressed  as  a
     percentage of net assets.  Shareholders pay an annual fee to the investment
     advisor for investment advisory and management  services.  The expenses and
     fees are deducted from fund income,  not from each shareholder.  The annual
     fee has a  contractual  expense limit  guarantee  based on the terms of the
     Investment  Advisory  Agreement.  (See  Note 2 in the  Notes  to  Financial
     Statements.)

Types of Money Market Securities

o    Asset-Backed Securities--debt securities that represent ownership in a pool
     of receivables, such as credit card debt, auto loans or mortgages.

o    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.

o    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.

o    Floating-Rate Notes (Floaters)--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).  Floaters are  considered  derivatives  because they "derive"
     their interest rates from their  designated base rates.  However,  floaters
     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 floaters to be inappropriate investments for money market funds.

o    U.S. Government Agency  Notes--intermediate-term  debt securities issued by
     U.S.  government  agencies  (such as the  Federal  Farm Credit Bank and the
     Federal Home Loan Bank). Some agency notes are backed by the full faith and
     credit  of the  U.S.  government,  while  most are  guaranteed  only by the
     issuing agency.  These notes are issued with maturities  ranging from three
     months to 30 years. Money market funds invest in these securities when they
     have remaining maturities of one year or less.
