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,  all of our computer systems have been modified,  tested and returned
to  production.  We have an ongoing  commitment  to testing our systems with our
vendors and business partners and within the industry throughout the rest of the
year.

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  to our testing  schedule,  our Y2K team has  developed  contingency
plans.  These  plans  will  minimize  the  impact on our  investors  and help us
maintain operations in the event of any Y2K-related  incidents.  We will conduct
practice  drills of  contingency  scenarios  during  the rest of 1999 and refine
those  plans 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.

MINIMIZE YOUR MUTUAL FUND TAX HIT

     American  Century's newest equity fund,  Tax-Managed Value, is designed for
long-term  growth  and to  minimize  the tax hit you  take on your  mutual  fund
investments  each year. The fund is managed to keep taxable  distributions  to a
minimum by using the following strategies:

     *  BUY AND HOLD --Low portfolio turnover helps limit realized capital gains
        and takes advantage of long-term capital gains tax rates.

     *  OFFSET GAINS --When gains are realized in the portfolio, they are offset
        with  capital  losses  from  securities  sold in that tax year or losses
        carried over from previous years.

     *  SELL HIGHER-COST  SHARES FIRST --Selling shares that cost the most first
        helps minimize the taxable gains incurred from a sale.

     During the six months  ended  June 30,  1999,  we  witnessed  a  surprising
turnaround  in the U.S.  economic  outlook.  When we last  addressed  you in the
annual  reports for the American  Century Equity  Growth,  Income & Growth,  and
Small Cap  Quantitative  funds,  the Federal Reserve (the U.S. central bank) had
recently  cut  short-term  interest  rates to bolster the U.S.  economy and help
stabilize markets worldwide.

     This came after economic and financial  crises in Asia,  Russia,  and Latin
America,  and the near  collapse of several  hedge  funds.  The global  economic
outlook was still quite  uncertain -- many  financial  observers  predicted slow
economic growth in the U.S. in 1999 and further interest rate cuts.

     Instead,  global economic conditions  rebounded.  By January 1999, overseas
economies were  stabilizing,  the U.S.  economy was posting  strong growth,  and
investor  confidence  had  returned.  Interest  rates rose while the U.S.  stock
market soared.

     Turning to the corporate  front,  here's an update on our  preparations for
Y2K.* Our  senior  level Year 2000  Steering  Committee,  computer  programmers,
business partners,  and Y2K team have been working diligently to make January 1,
2000, a non-event for American  Century  investors.  All of our computer systems
have been  modified,  tested,  and  returned to  production.  We have an ongoing
commitment  to testing our systems  with  vendors,  business  partners,  and the
mutual fund industry through the rest of the year.

     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.  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.

     Elsewhere  on the  corporate  front,  we  continued  to expand the American
Century  investment  team,  which has doubled over the past three  years.  We're
committed to building and maintaining a talented management group.

     As always, we appreciate your continued confidence in American Century.

Sincerely,

Report Highlights
- --------------------------------------------------------------------------------

MARKET PERSPECTIVE

*   U.S. stocks performed fairly well during the six months ended June 30, 1999.
    Large-cap  stocks  continued to enjoy  above-average  gains,  while mid- and
    small-cap shares posted more historically average returns.

*   Large-cap  growth stocks won the lion's share of gains during 1998, and that
    trend continued into early 1999.

*   The second quarter of 1999 clearly  demonstrated  the value of maintaining a
    diversified  stock  portfolio--investors  turned away from large-cap  growth
    stocks  and  instead  sought  attractively  priced  value and  small-company
    shares.

*   Cyclical   stocks--those  closely  tied  to  economic  ups  and  downs--also
    performed well during the second quarter.

*   The Federal Reserve raised short-term interest rates at the end of June to
    slow U.S. growth to a less inflationary pace.

EQUITY GROWTH

*   The fund  posted a notable  return  from a  historical  perspective  but was
    unable to match the gains of its benchmark, the S&P 500.

*   Equity  Growth's  underweight in many of the large-cap  companies that drove
    the S&P 500's narrowly concentrated, first-quarter gains was the main factor
    dampening performance.

*   In the second quarter,  Equity Growth  outperformed  the S&P 500 for some of
    the same reasons it underperformed during the first quarter.

*   Going  forward,  we're looking to enhance  performance  through an increased
    focus on what our models do best: find attractively valued stocks.

INCOME & GROWTH

*   The fund posted solid returns but trailed its benchmark, the S&P 500.

*   The  main  factor   detracting  from   performance  was  Income  &  Growth's
    underweight in many of the high-profile,  blue chip names that drove the S&P
    500 during the first quarter.

*   As investors  began eagerly  switching to value and small-cap  shares in the
    second quarter, Income & Growth outperformed the S&P 500.

*   Going forward,  we currently plan to stay fully invested in stocks and focus
    more on individual  stock  selection  rather than broad  industry  over- and
    underweightings.

SMALL CAP QUANTITATIVE

*   The fund finished the first half of 1999 little changed,  lagging the return
    of the S&P SmallCap 600 Index and the average  small-cap fund  (according to
    Lipper Inc.).

*   Small Cap  Quantitative  underperformed  its  benchmark  because  we avoided
    Internet shares.

*   We  concentrated  the portfolio in fewer stocks,  while  bringing the fund's
    industry weightings more in line with the index.

*   The outlook for small-cap stocks is generally  positive--economic  growth is
    healthy and small  stocks look like better  relative  values than  large-cap
    stocks.

Market Perspective from Mark Mallon
- --------------------------------------------------------------------------------

Mark Mallon, head of growth and income equity,  specialty,  and asset allocation
funds at American Century

MARKET SNAPSHOT

     U.S.  stocks  performed  fairly well  during the six months  ended June 30,
1999.  Large-cap stocks continued to enjoy  above-average  gains, while mid- and
small-cap shares posted more historically average returns. (See the accompanying
table.)

     Solid  corporate  earnings  and fairly  robust  U.S.  economic  growth kept
investor sentiment high and fueled gains in domestic equities.

THE SEEDS OF CHANGE

     Large-cap growth stocks won the lion's share of gains during 1998, and that
trend  continued into early 1999.  Stocks of companies  providing  above-average
earnings  growth  primarily   benefited  from  this  trend  thanks  to  investor
willingness to pay unprecedented prices.

     In addition, market leadership was very narrow. According to Morgan Stanley
Dean Witter,  just five stocks accounted for half of the S&P 500's return during
the first three months of 1999. A mere 18 accounted for the full 100%;  the rest
essentially  canceled each other out. (Because the S&P 500 is weighted by market
value,  the higher the total value of a company's  stock, the more it influences
index returns.)

     As a result,  the performance  disparity between large-cap growth and value
stocks  remained in place.  But  bellwether  growth  names  became  increasingly
expensive. And with U.S. economic growth showing few signs of wear and tear from
1998's global economic crises,  investors became less cautious and began to look
for better values elsewhere.

VALUE AND SMALL-CAP STOCKS SURGE

     That was the backdrop as the second  quarter of 1999 began--a  quarter that
clearly  demonstrated  the value of maintaining a diversified  stock  portfolio.
Turning away from large-cap growth stocks,  investors sought attractively priced
value and small-company  shares. Unlike growth stocks, value stocks tend to have
lower price/earnings ratios, meaning that investors pay less for earnings.

     Such shares were clear  favorites  during the  quarter--the  S&P  500/BARRA
Value Index,  a benchmark for the  performance of large-cap  value stocks,  rose
10.80%,  significantly  higher than the 3.83% return of the S&P 500/BARRA Growth
Index.  More impressive was the  performance of small-cap value shares:  the S&P
SmallCap 600/BARRA Value Index rose a stellar 19.91%, outpacing the S&P SmallCap
600/BARRA Growth Index, which jumped 11.11%.

     Cyclical  stocks--those  closely  tied  to  economic  ups  and  downs--also
performed well during the second  quarter.  Investors  greeted these stocks with
enthusiasm because of improving global economic conditions.

Market Perspective from Mark Mallon
- --------------------------------------------------------------------------------
                                                                    (Continued)

     That turn of events  allowed shares of aluminum,  chemicals,  construction,
and  diversified  machinery  companies to provide some of the  quarter's  better
returns.  Aluminum  was also one of the  better  performing  industries  for the
entire six months,  as were the  brokerage,  broadcast/media,  industrials,  and
semiconductor industries.

ECONOMIC UNDERPINNINGS

     The longest economic expansion in 50 years provided the springboard for the
stock market's continued gains. The remarkable U.S. economic engine surged ahead
at a 4.3%  annual  pace  during  the first  quarter,  accompanied  by  corporate
earnings  that were far  stronger  than  expected.  Improvements  in Pacific Rim
economies--where   Korea's  industrial   production  surged,   Taiwan's  leading
indicators rose, and Japan's economy showed signs of  life--enhanced  the global
economic outlook.

     The U.S.  economy  slowed  some in the second  quarter but still grew at an
estimated  2.3% annual pace.  Meanwhile,  U.S.  corporate  profits rose 16%--the
largest  quarterly gain in nearly four years. By the end of June, the three most
widely recognized U.S. stock indices--the Dow Jones Industrial Average,  the S&P
500, and the Nasdaq Composite--all hit record highs.

THE FED INTERVENES

     Impressive corporate earnings and economic strength attracted the attention
of the  Federal  Reserve  (the  Fed).  Just days after a May  announcement  that
consumer prices experienced their biggest monthly gain in almost nine years, the
Fed announced  that it had shifted to a  rate-raising  bias. On June 30, the Fed
went  further,  ratcheting  short-term  interest  rates a  quarter  of a percent
higher.  Viewed as a precautionary move, the widely expected increase had little
negative impact on U.S. financial markets.

     In fact,  stocks  staged a relief rally after the Fed revealed  that it had
reverted from its tightening bias to a neutral stance.  Many market participants
had  feared  that the  quarter-percent  hike might be just the first in a series
over the coming months. So investors were pleased with a sign that the Fed wants
further  evidence of  accelerating  inflation  before it raises  borrowing costs
again.

Equity Growth--Q&A
- --------------------------------------------------------------------------------
/photo of Kurt Borgwardt and John Schniedwind/

     Based on an interview with Kurt Borgwardt and John  Schniedwind,  portfolio
managers on the Equity Growth fund investment team.

HOW DID EQUITY GROWTH PERFORM FOR THE SIX MONTHS ENDED JUNE 30, 1999?

     The fund posted a notable  return  from a  historical  perspective  but was
unable to match the gains of its benchmark,  the S&P 500.  Equity Growth's total
return* was 8.11% for the six months,  compared with the S&P 500's 12.23% return
and the 11.65% average return of the 1174 "Growth Funds" tracked by Lipper Inc.

     Equity Growth's long-term performance remained sound. For the periods ended
June 30, 1999, Equity Growth's three-year,  five-year,  and life-of-fund returns
ranked the fund among the top 20% of its Lipper group.  (Please see the previous
page for fund performance comparisons.)

WHY DID THE FUND UNDERPERFORM?

     Equity  Growth's  underweighting  in many of the large-cap  companies  that
drove  the S&P 500's  narrowly  concentrated,  first-quarter  gains was the main
factor dampening  performance.  (See Mark Mallon's Market Perspective on pages 3
and 4.)

     A  significant  factor behind the dominance of such stocks was concern that
1998's global  economic  crises would  translate into slowing  economic  growth,
dragging  on the U.S.  economy  and the  profits  of  smaller,  less-diversified
companies.  Investors  therefore turned to the largest,  most-liquid  names, and
price/earnings  ratios on these shares rose ever higher,  meaning that investors
were willing to pay increasing  amounts for these  companies'  earnings.  Simply
put, the prices at which many of these stocks were trading seemed  unjustifiably
high to our models, so we maintained underweight positions.

     Equity Growth's tendency to maintain a more value-oriented bias than the S&
P 500 means that the stocks in the portfolio  were, on average,  more reasonably
priced  based  on  their  underlying   companies'  earnings  outlook,   business
fundamentals,  or intrinsic  value.  Since narrow market  leadership  prevailed,
however,  the attractive stocks that our models helped us find weren't as highly
rewarded as more-normal market conditions might have permitted.

WHAT  HAPPENED  TO FUND  RETURNS IN THE  SECOND  QUARTER  OF 1999,  WHEN  MARKET
SENTIMENT SHIFTED DIRECTION?

     In the second quarter,  Equity Growth  outperformed the S&P 500 for some of
the same reasons it had underperformed  during the first quarter.  Those reasons
include the fund's  value-stock  tilt, as well as its tendency to hold shares of
companies with slightly smaller market capitalizations.

Equity Growth--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

     As investors began eagerly switching to value and small-cap shares,  Equity
Growth's  returns  were  enhanced,   helping  the  fund  outpace  the  S&P  500.
Unfortunately,   second-quarter   outperformance  fell  shy  of  overcoming  the
first-quarter deficit.

ONE OF THE BETTER-PERFORMING INDUSTRIES DURING THE FIRST HALF OF 1999 WAS
INVESTMENT BANKING/BROKERAGE. WAS THERE A PARTICULAR STOCK IN THIS AREA THAT
YOUR MODELS LIKED?

     Yes.  The  portfolio's  sixth-largest  holding  at the end of June,  Morgan
Stanley  Dean  Witter,  is a good  example.  The  company is a global  financial
services  firm and market leader in  securities,  asset  management,  and credit
services.  During their quarter ended May 31, 1999,  the company  reported a 42%
increase in per-share earnings--a fairly impressive performance.

     Although  Morgan  Stanley  Dean  Witter's  securities  and credit  services
revenue was impressive,  their investment  banking  performance was particularly
noteworthy.  Thanks to proper  industry  positioning,  the  company  was able to
capitalize on the consolidation  trend many industries  experienced.  We've been
generally pleased by the results we've seen since adding the stock to the fund's
portfolio.  Since the  beginning  of this year,  shares of Morgan  Stanley  Dean
Witter have risen about 45%.

WHAT'S ANOTHER EXAMPLE OF A SOLID-PERFORMING STOCK THAT YOUR MODELS FAVORED?

     Shares of VISX, a world leader in the design, manufacture, and marketing of
proprietary  technologies and laser systems for vision correction,  was one. The
company  pioneered  the use of  excimer  lasers to reshape  the eye and  improve
vision  disorders,  and its  systems  are  currently  sold in over 60  countries
worldwide.

     Impressive earnings momentum was one of the things that made this company a
standout to our models.  Owning VISX shares was  particularly  rewarding  in the
first  half of  1999,  when  its  price  increased  from  $22 to $79.  That is a
substantial  gain and definitely the kind of  performance-enhancing  exposure we
like to have for Equity Growth.

WHAT CHOICES DETRACTED FROM RETURNS?

     The fund's relative  underweighting compared with the S&P 500 in several of
the media  industry's  better  performers  certainly  didn't  help  performance.
MediaOne is a prime  example.  The  company  provides  basic and  premium  cable
television  services  to  over  five  million  subscribers.  Recently,  MediaOne
introduced   high-speed  Internet  access,   telephone  services,   and  digital
television in some of its service areas.  The company also has interests in some
of the fastest-growing wireless communications businesses outside of the U.S.

Equity Growth--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

     When MediaOne  became an  acquisition  target of AT&T, a widely  recognized
name in the  communications  services industry and the most widely held stock in
the United States, its share price rose sharply.  However,  because media stocks
such as CBS were far more attractively valued, our models favored those instead

WHAT DO YOU SEE IN STORE FOR U.S. STOCKS FOR THE REST OF 1999?

     The good news is that  corporate  profits  remained  impressive  during the
second quarter, and with overseas economies rebounding, we believe prospects for
U.S. equities look fairly bright.

     However,  the good  corporate and economic  news has a dark side--it  might
cause the Federal Reserve to raise short-term interest rates again.

     Since higher  borrowing  costs tend to depress  stocks by  diminishing  the
present value of future corporate  earnings,  continued  increases in short-term
interest rates by the Fed could  conceivably lead to lower overall stock prices.
By the same token,  though, if growth moderates,  the market's tone could become
more upbeat and stocks could continue to rally.

GIVEN  THAT  OUTLOOK,  WHAT ARE YOUR  PLANS FOR THE  PORTFOLIO  FOR THE NEXT SIX
MONTHS?

     One  thing  worth  mentioning  is  that  we have  recently  fine-tuned  our
investment approach. We've found that our quantitative process is more effective
at picking  individual  stocks than  industries.  So rather  than  significantly
overweighting  and  underweighting  entire sectors compared with the S&P 500, we
have been  bringing our industry  positions  more in line with the index.  We're
looking to enhance  performance through an increased focus on what our models do
best: find attractively valued stocks.

     Another  focus will  likely be to keep  Equity  Growth  fully  invested  in
stocks.  When the  market  rallies,  this  strategy  tends to  enhance  returns.
However,  if the market  sells  off,  being  fully  invested  could also  dampen
performance.  To hold such a possibility to a minimum,  we will continue looking
to add shares of companies with improving  earnings  forecasts that appear to be
undervalued.

Income & Growth--Q&A
- --------------------------------------------------------------------------------

     Based on an interview with Kurt Borgwardt and John Schniedwind (pictured on
page 6), portfolio managers on the Income & Growth fund investment team.

HOW DID INCOME & GROWTH PERFORM FOR THE SIX MONTHS ENDED JUNE 30, 1999?

     The fund posted a noteworthy return but trailed its benchmark, the S&P 500.
Income & Growth's total return* was 9.69% for the six months,  compared with the
S&P 500's  12.23%  return and the  10.93%  average  return of the 922  "Growth &
Income Funds" tracked by Lipper Inc.

     Income & Growth's long-term returns remained impressive. For the year ended
June 30, 1999,  Income & Growth's  return ranked the fund among the top third of
its peers, while three-year,  five-year, and life-of-fund returns were among the
top 10% of its Lipper group.  (Please see the previous page for fund performance
comparisons.)

WHAT CAUSED THE FUND'S UNDERPERFORMANCE RELATIVE TO THE S&P 500?

     The main factor  detracting from performance was the fund's  underweighting
in many of the  high-profile,  blue chip names that drove the S&P 500 during the
first  quarter.  (See  Mark  Mallon's  Market  Perspective  on pages 3 and 4.) A
driving force behind the narrowly focused  dominance of such stocks was investor
concern that slower economic growth would follow 1998's global economic crises.

     That  predicted  slowdown in growth was  expected  to weigh  heavily on the
profits of smaller, less-diversified companies. As a result, investors looked to
the  perceived  safety  of  the  largest,   most  liquid  names,   which  caused
price/earnings  ratios  on these  stocks  to soar as  investors  demonstrated  a
willingness to pay ever-increasing amounts for these companies' earnings.  Since
these stocks were  trading at what seemed  excessive  prices to our models,  the
fund had a proportionally smaller exposure.

     Generally  speaking,  Income & Growth  tends to have a more  value-oriented
bias than the S&P 500. So the stocks in the  portfolio  were,  on average,  more
reasonably priced based on their underlying  companies'  business  fundamentals,
earnings outlook, or intrinsic value. Unfortunately, that didn't help returns as
much as more-normal market conditions might have allowed.

MARKET SENTIMENT SHIFTED DIRECTION IN THE SECOND QUARTER OF 1999. WHAT HAPPENED
TO FUND RETURNS THEN?

     As investors began eagerly switching to value and small-cap shares,  Income
& Growth's  returns were  enhanced.  So the same factors that  hindered  returns
during the first  quarter--the  fund's value-stock tilt and its tendency to hold
shares of companies  with smaller market  capitalizations  compared with the S&P
500--paid off handsomely, allowing Income & Growth to outperform. Unfortunately,
the fund's  second-quarter  outperformance of the S&P 500 fell a few percent shy
of overcoming its first-quarter deficit.

Income & Growth--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

WHAT WAS ONE OF THE FUND'S BETTER-PERFORMING STOCKS?

     Hewlett-Packard  (HP) shares  certainly  fall into that  category.  HP--the
fund's ninth-largest holding at the end of June--is a leading global provider of
computing  and imaging  solutions  and services for  businesses  and homes.  The
company is also focused on  capitalizing on Internet  opportunities,  as well as
the proliferation of electronic services.

     Our models were  attracted to HP shares  because of their  favorable  price
relative to the company's earnings,  which surpassed market expectations for the
third consecutive  quarter.  HP cited strong profit  performance in its printing
and imaging endeavors and solid earnings from personal computer sales as some of
the main catalysts for the positive results. Not surprisingly, the stock's price
reflected that upbeat performance--shares of HP rose almost 48% during the first
half of 1999.

THE INVESTMENT BANKING/BROKERAGE INDUSTRY WAS ONE OF THE BEST PERFORMERS IN THE
FIRST HALF OF 1999. DID YOU HAVE ANY STOCKS THERE THAT FARED WELL?

     Our models favored Morgan Stanley Dean Witter in particular. The company is
a global  financial  services  firm  and  market  leader  in  securities,  asset
management,  and credit  services.  Morgan  Stanley  Dean Witter  reported a 42%
increase in per-share earnings during their quarter ended May 31, 1999, a fairly
noteworthy  performance.  Behind  that gain was  impressive  revenue  from their
securities and credit services operations.

     More impressive was their investment banking  performance,  which benefited
from  the  trend  toward  increased   consolidation  in  many  industries.   Not
surprisingly, the company's solid performance has led to a sharp increase in its
stock: the price has risen about 45% since the beginning of this year.

THE MEDIA INDUSTRY ALSO FARED WELL DURING THE SIX MONTHS. HOW DID YOUR
SELECTIONS IN THIS AREA FACTOR INTO INCOME & GROWTH'S RETURNS?

     Though the fund certainly benefited from its holdings in this area, we were
underweight  in several of the  industry's  brighter  stars.  The main reason we
underweighted  such stocks was because their valuations were far less attractive
than shares of many other companies in the media industry, such as those of CBS.

     For example, the fund was underweight in shares of MediaOne. The company is
one of the nation's leaders in broadband  services,  providing basic and premium
cable television  services to over five million  subscribers.  MediaOne recently
introduced   high-speed  Internet  access,   telephone  services,   and  digital
television in some of its service areas.  The company also has interests in some
of the fastest-growing wireless communications businesses outside of the U.S.

     MediaOne shares rose sharply when the company became an acquisition  target
of AT&T--a widely  recognized name in the  communications  services industry and
the most widely held stock in the United  States.  So the fund's  underweighting
dampened performance relative to the S&P 500.

Income & Growth--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

WHAT'S YOUR OUTLOOK FOR U.S. STOCKS FOR THE REST OF 1999?

     The good news is that  corporate  profits  remained  impressive  during the
second  quarter,  and with  overseas  economies  rebounding,  prospects for U.S.
equities look fairly bright.  However, we've continued to see a wave of strength
in the latest economic  reports.  Whether that's a harbinger of continued strong
growth and additional  Federal  Reserve rate increases or whether those concerns
are overly bearish remains uncertain.

     Since higher  borrowing  costs tend to depress  stocks by  diminishing  the
present value of future corporate  earnings,  continued  increases in short-term
interest rates by the Fed could  conceivably lead to lower overall stock prices.
By the same token,  though, if growth moderates,  the market's tone could become
more upbeat and stocks could continue to rally.

GIVEN  THAT  OUTLOOK,  WHAT ARE YOUR  PLANS FOR THE  PORTFOLIO  FOR THE NEXT SIX
MONTHS?

     Remaining  fully  invested  in stocks  will most  likely  continue to be an
important  priority.  This  strategy  tends to enhance  returns  when the market
rallies.  However,  if the market  sells off,  being fully  invested  could also
dampen returns. To mitigate such a possibility,  we will keep looking for shares
of  companies  with  improving  earnings  forecasts  that  our  models  show  as
attractively  valued.  This strategy will hopefully provide investors with sound
returns and an acceptable level of risk.

     One  thing  worth  mentioning  is  that  we have  recently  fine-tuned  our
investment approach. We've found that our quantitative process is more effective
at picking  individual  stocks than  industries.  So rather  than  significantly
overweighting  and  underweighting  entire sectors compared with the S&P 500, we
have been  bringing our industry  positions  more in line with the index.  We're
looking to enhance performance through our increased focus on what our models do
best: find attractively valued stocks.

     For example, the portfolio was slightly  overweighted in financial services
stocks compared with the S&P 500 at period end. Going forward, the percentage of
financial  services  companies  in the fund will likely more  closely  track the
percentage  in the index.  If we decide to overweight  one company,  we'd likely
underweight  other  financial  services  holdings  to keep  the  overall  sector
weighting in line with the index.

Small Cap Quantitative--Q&A
- --------------------------------------------------------------------------------
/photo of Kurt Borgwardt and Bill Martin/

     An interview with Kurt Borgwardt and Bill Martin, portfolio managers on the
Small Cap Quantitative fund management team.

HOW DID SMALL CAP  QUANTITATIVE  PERFORM  DURING THE SIX  MONTHS  ENDED JUNE 30,
1999?

     Though the period was a volatile one for small-company stocks, returns were
relatively  flat (see Mark Mallon's  stock market  discussion on pages 3 and 4).
For the six  months,  Small  Cap  Quantitative  returned  1.06%,  while  the S&P
SmallCap 600 was up 5.04%.  By comparison,  the average return of the 777 "Small
Cap  Funds"  tracked  by Lipper  Inc.  was 8.56% for the same  period.  (See the
previous page for additional performance comparisons.)

WHY DID THE FUND UNDERPERFORM THE LIPPER GROUP?

     We can point to two reasons.  First, we don't  typically  invest in initial
public offerings (IPOs), though many small-cap funds do. The IPO market tends to
be volatile,  but it has enjoyed  tremendous  success  lately.  That limited our
performance relative to the peer group so far in 1999.

     Second, we manage the portfolio  against the S&P SmallCap 600 Index,  while
the vast  majority of our peers track the  Russell  2000 Index of  small-company
stocks. The Russell 2000 was up about 8.5% for the six months, which is right in
line with the peer group average return. The Russell outperformed because of its
heavier weighting in Internet stocks.  Internet shares  appreciated so much that
they went from about 4% of the Russell index a year ago to around 12% at the end
of June.

WHY DID YOU SELECT THE S&P 600 AS THE FUND'S BENCHMARK?

     We chose the S&P 600 for the fund's  benchmark  because  it's put  together
with  companies  selected  for size and industry  representation.  We think that
gives the fund a more sound, diversified benchmark than the Russell index, which
is  constructed  by taking the 3,000 largest U.S.  stocks and simply lopping off
the top 1,000.

EXPLAIN HOW YOU MANAGE SMALL CAP QUANTITATIVE RELATIVE TO THE INDEX.

     We use a  quantitative  approach  that  relies on  sophisticated  financial
models to help us make investment decisions. First, we use a stock-ranking model
to analyze more than 2,000 small-cap stocks. The model takes into account things
like earnings  growth and relative value in trying to rank these stocks based on
their expected total return. We use another computer model to create a portfolio
of high-ranking  stocks that matches the overall risk level of the S&P 600. Then
we conduct a fundamental review of the buy and sell decisions

Small Cap Quantitative--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

the  model  generates.   In  addition,  we  work  with  a  team  of  experienced
quantitative  analysts who are continually refining and improving our management
process.

DID  YOU  MAKE  ANY  REFINEMENTS  TO  THE  INVESTMENT  APPROACH  FOR  SMALL  CAP
QUANTITATIVE OVER THE LAST SIX MONTHS?

     Yes, we did. We've found that our  investment  process is more effective at
picking individual stocks than industries.  So rather than  significantly  over-
and underweighting  entire industries  relative to the index, we're bringing our
industry positions more in line with those of the S&P 600.

     At the same  time,  we have  been  trimming  the  number  of  stocks in the
portfolio.  We carefully  evaluated  each name,  concentrating  the portfolio in
fewer,  higher-ranking  stocks, as measured by our stock-ranking model. We think
running the fund "industry  neutral" with fewer  companies puts the portfolio in
the  best  position  to  benefit  from  what  our   quantitative   approach  has
historically done best--pick attractively valued individual stocks.

GIVE SOME EXAMPLES OF STOCKS THE MODEL PICKED THAT ENHANCED RETURNS.

     Two good  examples are  Cullen/Frost  Bankers and K-Swiss,  our two largest
holdings  at the end of June.  K-Swiss  is a stock  we've  held since the fund's
inception.  The company is probably best known for its line of tennis shoes, but
it also  markets  apparel  and  accessories.  The  stock  carries  a  reasonable
valuation, while it's seen healthy earnings growth in recent quarters because of
impressive retail sales in the U.S. For the six months,  the stock was up nearly
250%.

     However,  Cullen/Frost  may be a better  example of the model's  ability to
make  solid  individual  stock  picks,  finding  good  names  even  within  down
industries.

CAN YOU TALK A LITTLE MORE ABOUT CULLEN/FROST BANKERS?

     Cullen/Frost is a holding company for a group of Texas regional banks.  The
stock held up relatively  well even though most bank and financial  shares fared
poorly in the second quarter because of rising  interest  rates.  The company is
highly profitable and the dominant independent player in its area.  Cullen/Frost
shares were buoyed in the second quarter by the  announcement  of a $100 million
share buy-back plan. In addition, Cullen/Frost also completed the acquisition of
another, smaller Texas bank.

WHAT ABOUT THE PORTFOLIO'S POORER PERFORMERS SO FAR IN 1999?

     An example of stocks we held that didn't perform as well as we'd hoped were
those  of  title  insurance  companies.  Most  mortgage  lenders  require  title
insurance before they'll finance a real estate purchase,  so the volume of title
insurers' business depends on the number of home sales. Holding several of these
companies was a good play in 1998,  when interest rates plummeted and home sales
hit an  all-time  high.  But  higher  rates so far this year have  these  stocks
sailing into a headwind.  So despite the fact that title insurance companies had
the very characteristics the model likes in a stock, they still performed poorly
over the six months.

Small Cap Quantitative--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

WERE THERE ANY STOCKS IN THE INDEX YOU AVOIDED THAT ENDED UP PERFORMING WELL?

     The most glaring  example is E-Trade,  an online  discount  brokerage.  The
mania  for  Internet  stocks  in late  1998 and  early  1999  made  E-Trade  the
best-performing  stock in the S&P 600.  In fact,  its  shares  did so well  that
E-Trade  grew to twice the size of the next largest  company in the index.  Like
most Internet  stocks,  E-Trade's  valuation was astronomical and earnings still
less than stellar.  Of course,  our  quantitative  approach is geared toward the
opposite--earnings  momentum  at  attractive  prices.  As a result,  we  largely
avoided  E-Trade  and  other  Internet  shares.  That  goes  a long  way  toward
explaining the fund's underperformance relative to the benchmark.

WHAT'S YOUR OUTLOOK FOR SMALL-CAP STOCKS IN THE COMING MONTHS?

     We have a generally positive outlook.  First,  economic growth is good--the
U.S. economy continues to hum along, and we've had better-than-expected economic
news out of Southeast Asia and Japan.  Small-cap stocks tend to do better during
periods of robust  growth.  Value  shares also tend to do better in this type of
environment,  and value is one of the key  considerations in our stock selection
process.

     Another  potential  positive  for  small-cap  shares  is the  trend  toward
consolidation in many industries,  including insurance,  banking, utilities, and
natural  gas,  among  others.  We think  mergers  and  acquisitions  of  smaller
companies by larger players  should help support prices for small-cap  stocks in
many parts of the economy.

     Finally,  small-cap  stocks in  general  remain  very  attractively  valued
relative to large-cap and growth  stocks.  That means small stocks could hold up
better than larger  growth  stocks if interest  rates  continue to rise.  That's
because  when rates rise,  you expect to see the  highest-priced  stocks get hit
hardest.  Because small-cap stocks lagged last year, we feel they're much better
values than the typical large-cap stock right now.

GIVEN THAT OUTLOOK, HOW WILL YOU MANAGE THE FUND?

     We're  sticking to our  marching  orders--buying  small  companies  that we
believe are  undervalued.  That strategy hasn't done as well over the last year,
when only one thing  worked--large  size. The stock market's  narrow focus meant
many  investment  strategies and  disciplines  that worked well in the past just
weren't rewarded last year. We think the greater risk,  though, is in abandoning
a proven  long-term  strategy  to chase  performance  for a brief  period.  As a
result,  we currently plan to continue to run the fund industry neutral relative
to the index,  trying instead to enhance  performance  through  individual stock
selection.

UNDERSTANDING THE STATEMENTS OF ASSETS AND  LIABILITIES--This  statement details
what the fund owns (assets),  what it owes (liabilities),  and its net assets as
of the last day of the period.  If you subtract  what the fund owes from what it
owns,  you get the fund's net assets.  For each class of shares,  the net assets
divided  by the total  number of  shares  outstanding  gives you the price of an
individual share, or the net asset value per share.

NET ASSETS are also broken down by capital (money invested by shareholders); net
investment income not yet paid to shareholders or net investment losses, if any;
net gains earned on investments  but not yet paid to  shareholders or net losses
on investments (known as realized gains or losses); and finally, gains or losses
on  securities  still owned by the fund  (known as  unrealized  appreciation  or
depreciation).  This  breakdown  tells  you the  value  of net  assets  that are
performance-related,  such as investment  gains or losses,  and the value of net
assets that are not related to performance,  such as shareholder investments and
redemptions.

JUNE 30, 1999 (UNAUDITED)

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION -- American Century Quantitative Equity Funds (the corporation)
is  registered  under  the  Investment  Company  Act  of  1940  as  an  open-end
diversified  management investment company.  Equity Growth Fund (Equity Growth),
Income & Growth Fund  (Income & Growth) and Small Cap  Quantitative  Fund (Small
Cap  Quantitative)  (the  funds)  are  three  of the  six  funds  issued  by the
corporation.  Equity  Growth seeks capital  appreciation  by investing in common
stocks.  Income & Growth  seeks  dividend  growth,  current  income and  capital
appreciation  by  investing  in  common  stocks.  Small Cap  Quantitative  seeks
long-term  capital  appreciation by investing  primarily in equity securities of
small companies.  Each fund is authorized to issue three classes of shares:  the
Investor Class, the Advisor Class and the Institutional Class. The three classes
of shares  differ  principally  in their  respective  shareholder  servicing and
distribution  expenses and  arrangements.  All shares of each fund  represent an
equal pro rata  interest  in the net  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. Sale of the Advisor
Class and Institutional Class for Small Cap Quantitative had not commenced as of
the report date. 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 -- Portfolio  securities traded primarily on a principal
securities  exchange are valued at the last reported sales price, or the mean of
the  latest  bid and  asked  prices  where no last  sales  price  is  available.
Securities traded  over-the-counter are valued at the mean of the latest bid and
asked prices or, in the case of certain foreign securities, at the last reported
sales price,  depending on local  convention or regulation.  When valuations are
not readily  available,  securities  are valued at fair value as  determined  in
accordance with procedures adopted by the Board of Directors.

    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 -- Dividend income less foreign taxes withheld (if any) is
recorded as of the ex-dividend date.  Interest income is recorded on the accrual
basis and includes accretion of discounts and amortization of premiums.

    FUTURES  CONTRACTS -- The funds may enter into stock index futures contracts
in order to manage the funds' exposure to changes in market  conditions.  One of
the risks of entering into futures  contracts may include the  possibility  that
the changes in value of the contract may not correlate with the changes in value
of the underlying  securities.  Upon entering into a futures contract, the funds
are  required  to deposit  either  cash or  securities  in an amount  equal to a
certain percentage of the contract value (initial margin).  Subsequent  payments
(variation  margin)  are made or  received  daily,  in cash,  by the funds.  The
variation  margin is equal to the  daily  change  in the  contract  value and is
recorded as an unrealized  gain or loss. The funds  recognize a realized gain or
loss when the contract is closed or expires.  Net realized and unrealized  gains
or losses  occurring  during  the  holding  period of  futures  contracts  are a
component of realized gain (loss) on  investments  and  unrealized  appreciation
(depreciation) on investments, respectively.

    REPURCHASE AGREEMENTS -- The funds may enter into repurchase agreements with
institutions that the funds'  investment  manager,  American Century  Investment
Management,  Inc. (ACIM),  has determined are creditworthy  pursuant to criteria
adopted by the Board of  Directors.  Each  repurchase  agreement  is recorded at
cost. The funds require that the collateral, represented by securities, received
in a repurchase  transaction be transferred to the funds'  custodian in a manner
sufficient  to enable  the funds to obtain  those  securities  in the event of a
default under the repurchase  agreement.  ACIM monitors,  on a daily basis,  the
securities  transferred to ensure the value,  including accrued interest, of the
securities  under each repurchase  agreement is greater than amounts owed to the
funds under each repurchase agreement.

    JOINT  TRADING  ACCOUNT --  Pursuant  to an  Exemptive  Order  issued by the
Securities  and  Exchange  Commission,  the funds,  along with other  registered
investment  companies  having  management  agreements  with ACIM,  may  transfer
uninvested  cash  balances  into a joint  trading  account.  These  balances are
invested in one or more repurchase agreements that are collateralized by U.S.
Treasury or Agency obligations.

    INCOME  TAX  STATUS  -- It is  the  funds'  policy  to  distribute  all  net
investment  income  and net  realized  gains to  shareholders  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  TO SHAREHOLDERS -- Distributions to shareholders are recorded
on the ex-dividend date.  Distributions  from net investment income are declared
and paid quarterly for the funds.  Distributions from net realized gains for the
funds are expected to be declared and paid annually.

    The  character  of  distributions  made during the year from net  investment
income or net realized gains may differ from their ultimate characterization for
federal income tax purposes.  These differences  reflect the differing character
of  certain  income  items and net  realized  gains  and  losses  for  financial
statement and tax  purposes,  and may result in  reclassification  among certain
capital accounts.

    ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is the corporation's
distributor. Certain officers of FDI are also officers of the corporation.

2.  TRANSACTIONS WITH RELATED PARTIES

    The  corporation  has entered  into a Management  Agreement  with ACIM under
which ACIM provides the funds with investment  advisory and management  services
in  exchange  for a single,  unified  management  fee per class.  The  Agreement
provides that all expenses of the funds,  except brokerage  commissions,  taxes,
portfolio  insurance,  interest,  fees and expenses of the Directors 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 0.3380% to
0.52000% for Equity  Growth and Income & Growth and 0.5380% to 0.7200% for Small
Cap  Quantitative.  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 June 30, 1999, the effective annual
Investor Class  management fee was 0.68%,  0.68%,  and 0.88%, for Equity Growth,
Income & Growth, and Small Cap Quantitative, respectively.

    The Board of Directors 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 funds will pay ACIM an annual
distribution  fee equal to 0.25% and  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 funds.  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 June 30,  1999,  were  $242,670  and
$469,872 for Equity Growth and Income & Growth, respectively.

    Certain  officers and directors of the  corporation are also officers and/or
directors,  and,  as a  group,  controlling  stockholders  of  American  Century
Companies,  Inc., the parent of the corporation's  investment manager, ACIM, and
the corporation's transfer agent, American Century Services Corporation.

Share Class and Retirement Account Information
- --------------------------------------------------------------------------------

SHARE CLASSES

     Three  classes of shares  are  authorized  for sale by the funds:  Investor
Class, Advisor Class, and Institutional 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
is 0.25% higher than the total expense ratio of the Investor Class.

     INSTITUTIONAL  CLASS  shares  are  available  to  endowments,  foundations,
defined-benefit  pension  plans,  or  financial   intermediaries  serving  these
investors.   This  class   recognizes  the  relatively  lower  cost  of  serving
institutional customers and others who invest at least $5 million in an American
Century fund or at least $10 million in multiple  funds.  In  recognition of the
larger  investments and account  balances and  comparatively  lower  transaction
costs, the total expense ratio of the Institutional Class is 0.20% less than the
total  expense  ratio of the  Investor  Class  shares.  The  Advisor  Class  and
Institutional  Class had not  commenced as of June 30,  1999,  for the Small Cap
Quantitative fund.

     All  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)]
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 tax 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

INVESTMENT PHILOSOPHY AND POLICIES

     American  Century's  quantitative  equity funds are managed using  computer
models  as key tools in  making  investment  decisions.  A  stock-ranking  model
analyzes a sizable universe of stocks based on their expected return.  The model
looks at both growth and value measures such as cash flow,  earnings growth, and
price/earnings  ratio.  Once  the  stocks  are  ranked,  another  model  creates
portfolios that balance  high-ranking  stocks with an overall risk level that is
comparable to each fund's benchmark index.

     EQUITY  GROWTH seeks  capital  appreciation  by investing in a  diversified
portfolio of common  stocks.  Its goal is to achieve a total return that exceeds
the total return of the S&P 500.

     INCOME & GROWTH seeks current income and capital  appreciation by investing
in a  diversified  portfolio  of common  stocks.  Its goal is to achieve a total
return that exceeds the total return of the S&P 500. The fund's  management team
also targets a dividend yield that is higher than the yield of the S&P 500.

     SMALL CAP  QUANTITATIVE  seeks  capital  appreciation  by  investing in the
common stocks of smaller  companies.  Its goal is to achieve a total return that
exceeds the total return of the S&P SmallCap 600. Historically, small-cap stocks
have been more volatile than the stocks of larger, more-established companies.

COMPARATIVE INDICES

     The  following  indices  are  used  in  the  report  for  fund  performance
comparisons. They are not investment products available for purchase.

     The  S&P 500 is  composed  of 500  large-capitalization  stocks  traded  on
domestic exchanges. It is considered a broad measure of U.S. stock performance.

     The S&P MIDCAP 400 is composed of 400  mid-capitalization  stocks traded on
domestic  exchanges.  It is  considered  a  broad  measure  of  mid-sized  stock
performance.

     The S&P SMALLCAP 600 is composed of 600 small-capitalization  stocks traded
on domestic  exchanges.  It is considered a broad measure of small-company stock
performance.

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 of less than one year.

     The Lipper categories for the quantitative equity funds are:

     GROWTH FUNDS  (Equity  Growth)  --funds that  normally  invest in companies
whose  long-term  earnings  are expected to grow  significantly  faster than the
earnings of the stocks represented in the major unmanaged stock indices.

     GROWTH  &  INCOME   FUNDS   (Income  &  Growth)   --funds  that  combine  a
growth-of-earnings orientation and an income requirement for level and/or rising
dividends.

     SMALL  CAP  FUNDS  (Small  Cap  Quantitative)   --funds  that  limit  their
investments on the basis of the size of the company.

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 37-43.

PORTFOLIO STATISTICS

* NUMBER OF COMPANIES --the number of different  companies held by the fund on a
given date.

*  DIVIDEND  YIELD --a  percentage  return  calculated  by  dividing  the fund's
dividend distributions over the past year by its current share price.

* PRICE/EARNINGS (P/E) RATIO --a stock value measurement  calculated by dividing
a company's stock price by its earnings per share,  with the result expressed as
a multiple  instead of as a percentage.  (Earnings  per share are  calculated by
dividing the after-tax earnings of a corporation by its outstanding shares.)

* PORTFOLIO TURNOVER --the percentage of the fund's investment portfolio that is
replaced during a given time period, usually a year. Actively managed portfolios
tend to have higher  turnover than passively  managed  portfolios  such as index
funds.

* 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.)

EQUITY TERMS

* BLUE CHIP  STOCKS  --stocks  of the most  established  companies  in  American
industry.   They  are  generally  large,   fairly  stable  companies  that  have
demonstrated consistent earnings and usually have long-term growth potential.
Examples include General Electric and Coca-Cola.

* GROWTH  STOCKS  --generally  considered  to be stocks of  companies  that have
experienced  above-average  earnings  growth and appear  likely to continue such
growth.  These  stocks  often sell at high P/E ratios.  Examples can include the
stocks of technology, healthcare, and consumer goods companies.

* VALUE STOCKS  --generally  considered to be stocks that are purchased  because
they are relatively inexpensive. These stocks are typically characterized by low
P/E ratios.

* LARGE-CAPITALIZATION (LARGE-CAP) STOCKS --generally considered to be stocks of
larger-sized companies that make up the Dow Jones Industrial Average and the S&P
500.

* MEDIUM-CAPITALIZATION  (MID-CAP) STOCKS --generally considered to be stocks of
mid-sized companies that make up the S&P MidCap 400.

* SMALL-CAPITALIZATION (SMALL-CAP) STOCKS --generally considered to be stocks of
smaller-sized companies that make up the S&P SmallCap 600.

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.

The investment  objective may be based on the fund's  objective as stated in its

organizations based on its management style.

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 a 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.

For a definition of fund categories, see the Glossary.

*  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.

fund.  These  documents  contain  important  information  including  charges and
expenses, and you should read them carefully before you invest or send money.

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,  all of our computer systems have been modified,  tested and returned
to  production.  We have an ongoing  commitment  to testing our systems with our
vendors and business partners and within the industry throughout the rest of the
year.

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  to our testing  schedule,  our Y2K team has  developed  contingency
plans.  These  plans  will  minimize  the  impact on our  investors  and help us
maintain operations in the event of any Y2K-related  incidents.  We will conduct
practice  drills of  contingency  scenarios  during  the rest of 1999 and refine
those  plans 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.

MINIMIZE YOUR MUTUAL FUND TAX HIT

     American  Century's newest equity fund,  Tax-Managed Value, is designed for
long-term  growth  and to  minimize  the tax hit you  take on your  mutual  fund
investments  each year. The fund is managed to keep taxable  distributions  to a
minimum by using the following strategies:

     *  BUY AND HOLD --Low portfolio turnover helps limit realized capital gains
        and takes advantage of long-term capital gains tax rates.

     *  OFFSET GAINS --When gains are realized in the portfolio, they are offset
        with  capital  losses  from  securities  sold in that tax year or losses
        carried over from previous years.

     *  SELL HIGHER-COST  SHARES FIRST --Selling shares that cost the most first
        helps minimize the taxable gains incurred from a sale.


Our Message to You
- --------------------------------------------------------------------------------
/photo of James E. Stowers III and James E. Stowers, Jr./
James E. Stowers III, seated, with James E. Stowers, Jr.

     During the six months  ended  June 30,  1999,  we  witnessed  a  surprising
turnaround in the global  economic  outlook.  When we last  addressed you in the
annual report for the American Century Global Gold and Global Natural  Resources
funds,  the  Federal  Reserve  and a number  of other  world  central  banks had
recently cut  short-term  interest  rates to bolster the global economy and help
stabilize markets worldwide.

     This came after economic and financial  crises in Asia,  Russia,  and Latin
America.  Slower  global growth sent prices for many  commodities  to multi-year
lows in 1998.

     But global economic conditions improved, and by the second quarter of 1999,
overseas  economies had bottomed out or were on the mend. Better economic growth
and reduced supply generally helped commodity prices stabilize. That also led to
positive performance for global natural  resource-related  stocks. However, gold
and gold shares  continued  to be hampered  by supply  concerns  caused by world
central bank sales.

     At American Century,  we continued to expand our investment team, which has
doubled over the past three years. We're committed to building and maintaining a
talented management group.

     Elsewhere on the corporate front,  here's an update on our preparations for
Y2K.* Our  senior  level Year 2000  Steering  Committee,  computer  programmers,
business partners,  and Y2K team have been working diligently to make January 1,
2000, a non-event for American  Century  investors.  All of our computer systems
have been  modified,  tested,  and  returned to  production.  We have an ongoing
commitment  to testing our systems  with  vendors,  business  partners,  and the
mutual fund industry through the rest of the year.

     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.  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.

     As always, we appreciate your continued confidence in American Century.

Report Highlights
- --------------------------------------------------------------------------------

MARKET PERSPECTIVE

Gold

*   Gold  prices  were down 9% for the six  months  ended June 30,  1999.  World
    central bank gold sales were the primary reason for the decline.

*   The Bank of England  auctioned the first of its gold reserves in early July,
    sending the price of gold bullion to its lowest level in 20 years.

*   A poor  performance by gold made for a difficult six months for gold shares.
    For the six  months,  the FT-SE Gold Mines Index was down a little more than
    5%.

*   By region,  African  gold shares held up best,  while  North  American  gold
    companies were down 4.6%.  Australian  gold stocks  performed  worst,  their
    returns limited by the strength of the Australian  currency  relative to the
    U.S. dollar.

Natural Resources

*   Commodity prices  generally  bottomed out or rebounded during the first half
    of 1999. Better global growth was key to supporting commodity prices.

*   Oil prices rose  dramatically  because large  oil-producing  countries did a
    good job of cutting back on supply.

*   Higher oil prices  led to solid  returns  for  energy  stocks.  Smaller  oil
    exploration and service companies,  which are closely tied to changes in the
    price of oil, performed best.

*   Basic  materials  stocks  performed  very well,  particularly  in the second
    quarter,  when many  investors  rotated out of the largest growth stocks and
    into  more  attractively  valued  cyclical  stocks,  such as those of paper,
    metal, and mining companies.

GLOBAL GOLD

*   The fund's return reflected the generally poor environment for gold and gold
    shares over the past six months.

*   We reduced our stake in Barrick Gold, the fund's largest holding,  to better
    diversify the portfolio.

*   Because  of high  transaction  costs  and  volatile  asset  flows  caused by
    short-term  traders,  we've added a 2%  redemption  fee for Global Gold fund
    shares purchased after June 30, 1999 (see page 7 for more details).

*   The outlook for gold and gold shares is relatively  poor because the specter
    of world central bank gold sales continues to weigh on the price of gold.

GLOBAL NATURAL RESOURCES

*   For the six months ended June 30, Global  Natural  Resources  produced solid
    returns,  thanks  to  the  improved  outlook  for  the  global  economy  and
    stable-to-higher prices for many commodities.

*   The fund  lagged  its Lipper  group and  benchmark  because we  overweighted
    energy shares, which underperformed basic materials stocks.

*   We modified the fund's benchmark slightly,  capping a stock's representation
    at 5% of the index. We made the change to diversify the portfolio and reduce
    its concentration in a few of the largest energy stocks.

*   We have a  positive  outlook  for  commodities  and  global  commodity-based
    industries. That's because global growth seems to be improving.

GOLD BULLION

     The price of gold  bullion  continued to decline in the first half of 1999,
down about 9% through  June 30. Gold fell  further to a 20-year low in the first
week of July  after  the Bank of  England  auctioned  off the  first of its gold
reserves.

     Despite such low prices, the backdrop of mine supply and fabrication demand
for gold remains  surprisingly  positive.  Gold demand  surged early in 1999, up
about  two-thirds over the last three months of 1998 according to the World Gold
Council.  Better  economic  growth in Europe  and Asia was  behind  the surge in
demand.

     In terms of mine  supply,  some gold  producers  have  begun to cut back on
higher-cost production, which improves the fundamentals for the gold market. The
World Gold Council  estimates  that demand  currently  outstrips  mine supply by
about 1,000 metric tons.

     The supply shortfall is being made up by above-ground supply,  particularly
from world central bank reserves. World central banks are estimated to hold more
than a fifth of all  above-ground  gold. In mid-March,  Switzerland  announced a
plan to sell half its gold reserves.  The same month, the International Monetary
Fund  rolled  out a plan to sell gold to help fund a debt  relief  plan for poor
countries.  These  actions are bad for market  sentiment  because the sales mean
gold is viewed  less and less as an asset of last resort and more like a typical
commodity.

GOLD STOCKS

     Returns for gold stocks were negative,  reflecting the poor  performance of
the  underlying  metal.  Lower gold prices squeeze  profits for gold  companies,
bringing  down their stock  prices.  For the six months ended June 30, the FT-SE
Gold Mines Index fell a little more than 5%.

     By region, African gold shares held up best. With gold trading so low, some
African  companies  moved to cut costs by laying off workers and closing  mines.
African gold stocks were also helped by weakness in the South African  currency,
the rand, which declined against the dollar. Gold is priced in dollars, so South
African companies book more profits when their currency declines relative to the
dollar.

     The opposite  happened to Australian gold shares--the  Australian  currency
strengthened  against the dollar,  limiting  profits in local currency terms. In
addition,  operational  difficulties  weighed  on the  stock  prices  of two big
Australian gold companies.

     North American gold stocks  produced  negative  returns for the six months,
with larger companies  holding up best.  Smaller gold exploration  companies are
closely  tied to the  performance  of the  underlying  metal,  so  they  tend to
underperform  the  larger,  more-diversified  gold  companies  when gold  prices
decline.

Market Perspective from Mark Mallon
- --------------------------------------------------------------------------------
                                                                    (Continued)
COMMODITIES

     Commodity prices generally  stabilized  during the first six months of 1999
after  reaching  multi-year  lows in 1998.  For the six  months,  the  Commodity
Research Bureau  Commodities Index was down about 3.5%.  Meanwhile,  the Goldman
Sachs Commodities Index rose about 15%. The reason for the disparity is that the
Goldman  index is more  heavily  weighted  toward  energy,  and oil prices  rose
sharply during the six months.

     Better  global  economic  growth so far this year  helped  support  prices.
Global growth is key for commodity  markets because it helps determine the level
of commodities  demand.  In the second  quarter,  Japan and many Southeast Asian
countries reported  stronger-than-expected  economic figures. In addition,  many
analysts upwardly revised their global economic growth projections.

     While demand for many commodities  firmed up, too much supply kept a lid on
prices.  The dramatic slowdown in the world economy last year led to the buildup
of big  surpluses  for  many  commodities.  That's  particularly  true of  basic
materials, including steel, copper, and aluminum.

     Unlike  most  commodities,  oil  prices  rose  dramatically  during the six
months.  Reduced supply played an important part in the increase.  OPEC and many
of the world's  other  leading  oil-producing  countries  combined to reduce oil
production by more than two million barrels a day.  Meanwhile,  demand for crude
oil  remained  strong.  Less supply and greater  demand  helped crude oil prices
rebound  from a  12-year  low near $10 a barrel  in late 1998 to more than $19 a
barrel by June.

NATURAL RESOURCES STOCKS

     Stocks of natural  resource-related  companies  bounced back sharply in the
first half of 1999.  Shares of basic material  companies  outperformed  those of
energy companies for the six months (see the graph at top left).

     Energy stocks benefited from the rebound in oil prices.  Large,  integrated
oil companies  performed well but lagged the shares of mid- and  small-sized oil
exploration and service companies (see the graph at bottom left). That's because
the  performance  of these  smaller  stocks is more closely tied to the price of
crude oil, which has nearly doubled since late 1998.

     So far in 1999, basic materials stocks also have performed much better than
in 1998. The rebound  occurred during the second  quarter,  when the outlook for
the global economy improved.  Investors rotated out of large, high-priced growth
stocks and into more  attractively  valued cyclical stocks.  Cyclical stocks are
those that  closely  track the health of the  economy  and include the shares of
paper, metal, and mining companies.

Global Gold--Q&A
- --------------------------------------------------------------------------------
/photo of Bill Martin/

     An  interview  with Bill  Martin,  a  portfolio  manager on the Global Gold
investment team.

HOW DID GLOBAL GOLD PERFORM DURING THE SIX MONTHS ENDED JUNE 30, 1999?

     The  portfolio's  return  reflected the poor  performance  of gold and gold
shares.  For the first half of the year,  Global  Gold had a return of  -7.84%,*
while the 43 gold-oriented funds tracked by Lipper Inc. had an average return of
- -3.12%. The fund's custom  benchmark--which  is about two-thirds North American,
20% or so African, and about 10% Australian gold stocks--returned -6.13% for the
same period. (See the previous page for additional performance comparisons).

WHY DID GLOBAL GOLD UNDERPERFORM THE LIPPER GROUP?

     We manage  Global  Gold as more of a pure play on the gold  market  than do
many of the funds in the Lipper  group.  Because they tend to hold more non-gold
stocks than we do, they often outperform when gold falls. But that also means we
tend to do better when gold prices rise, as happened in April.

     Unfortunately,  news of the intended gold sales by the Bank of England took
the wind out of the market's  sails in May (see Mark Mallon's  discussion of the
gold market on page 3 for more  details).  Financial  Research  Corp.  estimates
investors  pulled almost $200 million from gold funds after the  announcement in
May. The total capitalization of the gold market is only about $30 billion--only
a little bigger than Internet company Yahoo!  alone--so volatile asset flows can
have a big impact on gold shares.  Not only is the market  relatively small, but
it's also thinly  traded,  which means  moving in and out of these stocks can be
costly and exacerbate losses.

ARE HIGH TRANSACTION  COSTS AND VOLATILE FUND FLOWS WHY AMERICAN CENTURY APPLIED
A 2% REDEMPTION FEE TO GLOBAL GOLD STARTING JUNE 30, 1999?

     Yes.  Short-term market timers increase the fund's transaction costs, which
are borne by all  shareholders.  The fee means  we're just asking day traders to
pay their  fair  share of the cost of doing  business  in gold.  Here's  how the
redemption  fee works:  Shares of Global Gold that are purchased  after June 30,
1999, and are redeemed or exchanged  within 180 days of purchase will be subject
to a 2% redemption fee. Shares will be redeemed on a first-in/ first-out basis.

     Here are the most important  points for existing  shareholders.  First, all
monies  invested  in the fund prior to June 30, 1999 will be  grandfathered  and
will not be subject to the redemption  fee.  Second,  the fee is retained by the
fund to benefit  long-term  shareholders.  The policy is intended  to  encourage
long-term investment in the fund, as

Global Gold--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

well as to decrease  the  negative  impact that  short-term  traders have on the
shareholders remaining in the fund.

DID YOU MAKE ANY OTHER CHANGES TO HELP IMPROVE THE FUND'S LIQUIDITY?

     Yes.  We want to  increase  the  fund's  liquidity  and reduce the costs of
buying  and  selling  portfolio  stocks.  But  that  can be  very  hard to do by
investing only in gold shares.  As a result,  we've taken a very modest position
(just 5% or so of assets) in more liquid  precious metal names,  like Impala,  a
platinum  stock.  We've added only stocks that have a very high  correlation  to
gold shares.  We think that's the best way to add  liquidity  and still give our
shareholders an investment that moves in line with gold.

YOU ALSO MADE SOME OTHER CHANGES TO THE PORTFOLIO. CAN YOU EXPLAIN THOSE
ADJUSTMENTS?

     We made some modest changes to diversify the portfolio.  The biggest change
was to reduce our stake in Barrick,  the fund's largest holding,  from about 19%
to 12% of fund  investments  (see the  chart at  right).  Barrick  is by far the
largest stock in the index, at about a quarter of the benchmark. We're committed
to giving investors  exposure to the entire gold market,  but we didn't think it
was in our  shareholder's  best  interests  to have such a large  weighting in a
single company. In addition,  having such a highly concentrated  portfolio could
have run up against  IRS  diversification  requirements,  which  prevent us from
holding very large weightings in individual  names. But we should point out that
we still have the ability to take  relatively  big positions in the largest gold
stocks if we feel the need to do so.

HOW DO VALUATIONS FOR GOLD COMPANIES LOOK WITH GOLD PRICES AT SUCH LOW LEVELS?

     We were much more comfortable with valuations at the end of 1998, when gold
was  trading  at around  $290 an ounce.  But with gold  trading at about $250 an
ounce and production  costs running at around $200, the premium we're paying for
many gold stocks is high. For example,  the very biggest gold stocks are trading
at 2.5-3 times their net asset value,  an estimate of the worth of their gold in
the  ground  that  also  makes  allowances  for  hedging  activity  and  capital
expenditures.  That premium is very high by historical standards. That's another
reason we decided to put a small portion of assets in some near-gold  names like
Impala--not only are they more liquid,  but they're also just much better values
right now.

YOU OFTEN SAY GOLD STOCKS ARE HIGHLY LEVERAGED TO THE PRICE OF GOLD. CAN YOU
GIVE AN EXAMPLE OF WHAT YOU MEAN?

     A good rule of thumb is that for every one  percent  change in the price of
gold bullion, gold shares should move two to three percent.  That's what we mean
by leverage.  Here's an example.  Today gold is trading at around $250 an ounce,
and let's assume a hypothetical  company with production costs of $200 an ounce.
Now if gold were to rally from $250 to $300, that would be an increase of 20% in
the price of the underlying  metal. But the profit of the company in the example
doubles  from $50 an ounce to $100.  So in this  example,  a 20% increase in the
price of gold translated into a 100% rise in gold company  profits.  That's what
we mean when we say gold companies are highly leveraged to the price of gold.

Global Gold--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

And that's why we're committed to giving our shareholders exposure to the entire
gold market, positioning the fund to benefit from any increase in gold prices.

WHAT'S THE OUTLOOK FOR GOLD?

     Despite a  favorable  backdrop  of more  demand and less mine  supply,  the
outlook for gold and gold shares is relatively poor. That's because above-ground
supply from world central banks and forward sales by gold  companies is weighing
on the  price of gold  bullion.  Lower  gold  prices  would  lead you to  expect
negative  returns for gold stocks,  but we could see gold stocks  perform poorly
even if gold's price is unchanged six months from now. That's because the prices
of gold stocks relative to the value of their  underlying  assets are so high by
historical standards.

WHAT'S THE  RELATIONSHIP  BETWEEN CENTRAL BANK GOLD SALES AND FORWARD SELLING BY
CORPORATIONS, AND WHY IS IT IMPORTANT FOR THE GOLD MARKET?

     In a forward  sale, a mining  company  borrows gold from a central bank and
sells it to lock in current  prices and hedge  against  future  declines  in the
price of gold. Central banks are willing to lease gold for forward sales because
they're eager to earn a return on their assets. Heavy forward sales are negative
for the market because they increase  supply and indicate that companies  expect
gold's price to decline.

     But world  central bank sales have reduced the amount of gold  available to
lease,  increasing  gold lease rates.  Much higher lease rates in recent  months
have begun to reduce the  incentive  for producer  forward  sales at a time when
gold demand is surging. This is one factor working in gold's favor.

WHAT ARE SOME OTHER POTENTIAL POSITIVES FOR GOLD?

     The global  economy is improving,  which also  increases the  likelihood of
inflation.  Better global growth or unexpected inflation should boost demand for
gold.

     Looking out a little  further,  potential  positives for gold are questions
about the  reappointment of U.S. Federal Reserve Chairman Alan Greenspan,  whose
third term expires  June 2000.  Greenspan  is one of the key  architects  of the
low-inflation,  moderate-growth  economy. If his reappointment gets caught up in
election-year  politics,  that could roil the  financial  markets  and send some
investors looking for the safety of gold and gold shares.

GIVEN THAT OUTLOOK, HOW WILL YOU POSITION THE FUND?

     We plan to  continue  to run the fund for  investors  who want a  long-term
portfolio diversifier. That means we'll try to position the fund to benefit from
a rally in gold or gold shares,  similar to what we saw in April.  Nevertheless,
we'll keep a small portion of assets, say 5% or so, in more liquid, attractively
valued  near-gold  names to try and increase the fund's  liquidity.  That should
help us minimize the impact that volatile asset flows have on the fund.

Global Natural Resources--Q&A
- --------------------------------------------------------------------------------
/photo of Joe Sterling/

     An interview with Joe Sterling,  a portfolio  manager on the Global Natural
Resources investment team.

HOW DID GLOBAL  NATURAL  RESOURCES  PERFORM DURING THE SIX MONTHS ENDED JUNE 30,
1999?

     The fund produced  solid returns but lagged its benchmark and other natural
resources funds. For the first half of the year,  Global Natural Resources had a
return of 17.83%,* while the 58 natural  resources  funds tracked by Lipper Inc.
had an average  return of  26.82%.  The  fund's  benchmark--an  index made up of
companies in the Basic Materials and Energy sectors of the Dow Jones World Stock
Index--returned  22.37%  for  the  period.  However,  Global  Natural  Resources
continues  to have solid  longer-term  returns,  ranking in the top third of its
Lipper group for the one- and three-year periods ended June 30 (see the previous
page for additional performance comparisons).

CAN YOU EXPLAIN YOUR MANAGEMENT APPROACH FOR GLOBAL NATURAL RESOURCES?

     We  manage  the  fund to  deliver  a pure  play on  global  commodity-based
industries.  To do that,  we run Global  Natural  Resources  against a benchmark
that's composed of companies from eight industries in 30 countries.  In terms of
broad sector  weightings,  the index is about 75% energy and 25% basic materials
shares.

     We use  sophisticated  financial  models to help us decide which sectors to
over- and  underweight,  as well as determine  the level of risk we want to take
relative  to the index.  Then we conduct a  fundamental  review of every buy and
sell  decision the models  generate.  Recently,  we've  instituted a policy that
limits any single company to no more than 5% of the benchmark.

CAN YOU TALK A LITTLE  BIT MORE ABOUT THE MINOR  ADJUSTMENT  YOU MADE TO THE WAY
YOU CONSTRUCT THE BENCHMARK AND WHAT THAT MEANS FOR THE FUND?

     We felt it was necessary to cap a stock's representation in the index at no
more than 5% because of some big mergers in the energy  sector  last year,  when
British  Petroleum  acquired  Amoco and Exxon acquired  Mobil,  though that deal
hasn't  closed yet.  Those were some of the biggest  companies  in the index and
four of the fund's  five  largest  holdings  last year.  If we hadn't  made some
adjustment to the benchmark, about 30% of the index would have been concentrated
in just these few stocks.

     Because we manage the fund  against the  benchmark,  we would have ended up
with a much more  concentrated  portfolio.  We just didn't think that was in our
shareholders'  best  interests.   That  also  could  have  run  up  against  IRS
diversification   requirements,   which  prevent  us  from  holding  very  large
weightings in individual names.

Global Natural Resources--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

     In practice, the change means we've reduced our exposure to the largest oil
companies.  For example,  at the end of last year, Exxon was our largest holding
at 11% of fund  investments.  Six months later, it still tops the list, but it's
now only about 5% of fund  investments  (see the graph at right).  But we should
point out that we still have the ability to  overweight  these stocks if we feel
the need to do so.

WHY DID THE FUND UNDERPERFORM ITS BENCHMARK?

     The  best  way to  understand  fund  performance  is to look at our  sector
weightings.  We continued to overweight  energy and underweight  basic materials
shares relative to the benchmark.  Within energy, we preferred large, integrated
oil companies to the smaller (and more volatile) exploration and service stocks.
But basic materials  outperformed  energy for the six months.  In addition,  our
preference for larger energy stocks limited returns.  When crude oil prices rise
sharply,  small- and  mid-size  energy  stocks  outperform  the shares of larger
energy companies. And that's exactly what happened over the last six months.

LET'S TALK ABOUT THE PORTFOLIO'S PERFORMANCE RELATIVE TO THE PEER GROUP. GLOBAL
NATURAL RESOURCES HAS DONE WELL FOR LONGER PERIODS, BUT CAN YOU EXPLAIN  WHY IT
LAGGED THE LIPPER GROUP IN  RECENT MONTHS?

     Basically,  the strategy  that worked well last year hasn't paid off so far
in 1999.  Last  year was  difficult  for  natural  resources  stocks,  with many
small-cap and emerging market stocks  experiencing  sharp losses.  We earned the
top Lipper  ranking in 1998  (ranking #1 out of 57 natural  resources  funds) by
avoiding such volatile sectors,  taking limited risks relative to the benchmark,
and overweighting large, integrated oil stocks.

     That  positioning  hasn't worked as well this year.  We were  underweighted
relative to the Lipper group in the basic  materials and emerging  market stocks
that  performed  best in recent  months.  In  general,  the worse a sector's  or
company's  stock market  performance  in 1998, the better its return so far this
year. Emerging market natural resource-related stocks are a great example of the
phenomenon--after  plummeting last year,  they've  performed very well so far in
1999.

YOU OFTEN SAY GLOBAL GROWTH IS KEY TO THE FUND'S SUCCESS. WHAT'S YOUR OUTLOOK
FOR THE GLOBAL ECONOMY?

     We have a generally positive outlook.  We expect global growth to be better
than last year, when the world economy expanded only about 1.5%. Better economic
growth would lead you to expect  higher  commodity  prices.  We've  already seen
commodity prices stabilize this year as a result of stronger demand.

     But we shouldn't overstate our enthusiasm. The recovery and growth rates we
see for Europe, Japan, and China--all big commodities consumers--are modest (see
the economic  growth forecast chart on the following  page). In addition,  there
are still large supply  overhangs  for many  commodities.  We'd have to work off
some  of  that  excess  supply  before  we  get  the  next  leg  of  the  rally.
Nevertheless,  the fund's healthy  returns in recent months give you an idea how
important even modest  improvements  in the economic  outlook can be for natural
resource-related stocks.

Global Natural Resources--Q&A

                                                                    (Continued)

WHAT'S YOUR OUTLOOK FOR BASIC MATERIALS?

     There's  been a rotation  by  investors  into this  sector,  and a stronger
economy also argues for better  performance  from stocks such as paper,  metals,
and chemicals.  In addition,  we can point to some mine  closures,  which should
help alleviate supply concerns for metals stocks.  And though they've  performed
reasonably  well so far this year, we believe these shares may have more room to
run.

AND HOW DO ENERGY STOCKS LOOK GOING FORWARD?

     Energy stocks track the price of crude oil, which depends on OPEC's ability
to limit production.  Assuming they can continue to hold down production,  crude
prices and corporate  earnings  should remain high.  What's more, as we approach
winter,  demand  should  pick up.  That would  argue for higher oil  prices.  In
addition, some large, integrated oil companies have announced that they're going
to increase their  exploration and production  budgets.  That could be very good
news for smaller oil service companies that depend on this spending.

     A warm winter would be a threat to this outlook for oil and oil stocks.  In
addition,  high oil prices tempt OPEC members to cheat and increase supply. That
situation  bears  watching,  particularly  as oil  prices  creep up above  $22 a
barrel.

HOW DO YOU EXPECT TO POSITION GLOBAL NATURAL RESOURCES IN THE COMING MONTHS?

     We plan to  continue to manage the fund for  shareholders  that want a pure
play on global growth trends and commodity-based  industries. In terms of sector
allocations,  we'll make modest  adjustments to the portfolio's energy and basic
material sector weightings as the economic and risk/reward outlook dictate.

UNDERSTANDING THE STATEMENTS OF ASSETS AND  LIABILITIES--This  statement details
what the fund owns (assets),  what it owes (liabilities),  and its net assets as
of the last day of the period.  If you subtract  what the fund owes from what it
owns,  you get the fund's net assets.  For each class of shares,  the net assets
divided  by the total  number of  shares  outstanding  gives you the price of an
individual share, or the net asset value per share.

NET ASSETS are also broken down by capital (money invested by shareholders); net
investment income not yet paid to shareholders or net investment losses, if any;
net gains earned on investments  but not yet paid to  shareholders or net losses
on investments (known as realized gains or losses); and finally, gains or losses
on  securities  still owned by the fund  (known as  unrealized  appreciation  or
depreciation).  This  breakdown  tells  you the  value  of net  assets  that are
performance-related,  such as investment  gains or losses,  and the value of net
assets that are not related to performance,  such as shareholder investments and
redemptions.

JUNE 30, 1999 (UNAUDITED)

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION -- American Century Quantitative Equity Funds (the corporation)
is registered under the Investment Company Act of 1940 as an open-end management
investment company.  Global Gold Fund (Global Gold) and Global Natural Resources
Fund (Global  Natural  Resources) (the funds) are two of the six funds issued by
the corporation. The funds are non-diversified under the 1940 Act. Global Gold's
investment  objective is to seek to realize a total return  (capital  growth and
dividends)  consistent  with  investment  in  securities  of companies  that are
engaged  in  mining,  processing,  fabricating  or  distributing  gold or  other
precious  metals  throughout  the world.  Global Natural  Resources'  investment
objective is to seek to realize a total return  consistent  with  investment  in
companies that are engaged in the natural resources  industry.  The funds invest
primarily in equity securities. The funds are 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 funds 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.  Sale of the Advisor Class for Global
Natural  Resources  commenced  on April  26,  1999.  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 -- Portfolio  securities traded primarily on a principal
securities  exchange are valued at the last reported sales price, or the mean of
the  latest  bid and  asked  prices  where no last  sales  price  is  available.
Securities traded  over-the-counter are valued at the mean of the latest bid and
asked prices or, in the case of certain foreign securities, at the last reported
sales price,  depending on local  convention or regulation.  When valuations are
not readily  available,  securities  are valued at fair value as  determined  in
accordance with procedures adopted by the Board of Directors.

    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 -- Dividend income less foreign taxes withheld (if any) is
recorded as of the ex-dividend date.  Interest income is recorded on the accrual
basis and includes accretion of discounts and amortization of premiums.

    FOREIGN  CURRENCY  TRANSACTIONS  -- All  assets  and  liabilities  initially
expressed in foreign  currencies are translated into U.S.  dollars at prevailing
exchange  rates at period end.  Purchases  and sales of  investment  securities,
dividend and interest  income,  and certain expenses are translated at the rates
of exchange prevailing on the respective dates of such transactions.  For assets
and  liabilities,  other  than  investments  in  securities,  net  realized  and
unrealized  gains and  losses  from  foreign  currency  translations  arise from
changes in currency exchange rates.

    Net  realized  and  unrealized  foreign  currency  exchange  gains or losses
occurring during the holding period of investment  securities are a component of
realized gain (loss) on investments and unrealized  appreciation  (depreciation)
on investments, respectively.

    FORWARD  FOREIGN  CURRENCY  EXCHANGE  CONTRACTS  -- The funds may enter into
forward  foreign  currency  exchange  contracts to  facilitate  transactions  of
securities  denominated in a foreign currency or to hedge the fund's exposure to
foreign  currency  exchange  rate  fluctuations.  The net U.S.  dollar  value of
foreign  currency  underlying all contractual  commitments held by the funds and
the resulting unrealized appreciation or depreciation are determined daily using
prevailing  exchange rates. The funds bear the risk of an unfavorable  change in
the  foreign   currency   exchange  rate   underlying   the  forward   contract.
Additionally,  losses may arise if the  counterparties  do not perform under the
contract terms.

    REPURCHASE AGREEMENTS -- The funds may enter into repurchase agreements with
institutions that the funds'  investment  manager,  American Century  Investment
Management,  Inc. (ACIM),  has determined are creditworthy  pursuant to criteria
adopted by the Board of  Directors.  Each  repurchase  agreement  is recorded at
cost. The funds require that the collateral, represented by securities, received
in a repurchase  transaction be transferred to the fund's  custodian in a manner
sufficient  to enable  the funds to obtain  those  securities  in the event of a
default under the repurchase  agreement.  ACIM monitors,  on a daily basis,  the
securities  transferred to ensure the value,  including accrued interest, of the
securities  under each repurchase  agreement is greater than amounts owed to the
funds under each repurchase agreement.

    JOINT  TRADING  ACCOUNT --  Pursuant  to an  Exemptive  Order  issued by the
Securities  and  Exchange  Commission,  the funds,  along with other  registered
investment  companies  having  management  agreements  with ACIM,  may  transfer
uninvested  cash  balances  into a joint  trading  account.  These  balances are
invested in one or more repurchase agreements that are collateralized by U.S.
Treasury or Agency obligations.

    INCOME  TAX  STATUS  -- It is  the  funds'  policy  to  distribute  all  net
investment  income  and net  realized  gains to  shareholders  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  TO SHAREHOLDERS -- Distributions to shareholders are recorded
on the ex-dividend date.  Distributions  from net investment income are declared
and paid  semiannually.  Distributions  from net realized gains are declared and
paid annually.

    The  character  of  distributions  made during the year from net  investment
income or net realized gains may differ from their ultimate characterization for
federal income tax purposes.  Those differences  reflect the differing character
of  certain  income  items and net  realized  gains  and  losses  for  financial
statement  and tax purposes  and may result in  reclassification  among  certain
capital accounts.

JUNE 30, 1999 (UNAUDITED)

    At  December  31,  1998,  Global  Gold  and  Global  Natural  Resources  had
accumulated net realized capital loss carryovers for federal income tax purposes
of $75,400,427  and  $1,574,913,  respectively,  (expiring 2005 through 2006 for
Global Gold and 2006 for Global Natural  Resources)  which may be used to offset
future taxable gains.

    ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is the corporation's
distributor. Certain officers of FDI are also officers of the corporation.

2.  TRANSACTIONS WITH RELATED PARTIES

    The  corporation  has entered into a Management  Agreement with ACIM,  under
which ACIM provides the funds with investment  advisory and management  services
in  exchange  for a single,  unified  management  fee per class.  The  Agreement
provides that all expenses of the funds,  except brokerage  commissions,  taxes,
portfolio  insurance,  interest,  fees and expenses of the Directors 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 0.3380% to
0.5200% 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 June 30, 1999,  the effective  annual  Investor
Class management fee was 0.68% for Global Gold and Global Natural Resources.

    The Board of Directors 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 funds will pay ACIM an annual
distribution  fee equal to 0.25% and  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 funds.  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 June 30,  1999 were $28 for Global
Gold and $10 for Global Natural Resources.

    Certain  officers and directors of the  corporation are also officers and/or
directors,  and,  as a  group,  controlling  stockholders  of  American  Century
Companies,  Inc., the parent of the corporation's  investment manager, ACIM, and
the corporation's transfer agent, American Century Services Corporation.

Share Class and Retirement Account Information
- --------------------------------------------------------------------------------

SHARE CLASSES

     Two classes of shares are authorized for sale by the funds: 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
is 0.25% higher than the total expense ratio of the Investor Class.

     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)]
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 tax 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 four  "specialty"  funds that  concentrate  their
holdings  in specific  industries  or sectors of the stock  market.  These funds
typically  respond  differently  than general equity funds to changing market or
economic conditions.  The funds are managed to provide a broad representation of
the  respective  industries.  Due to the limited focus of these funds,  they may
experience  greater  volatility than funds with a broader  investment  strategy.
They are not intended to serve as a complete  investment  program by themselves.
International   investing  also  involves  special  risks,   such  as  political
instability and currency fluctuations.

     GLOBAL GOLD seeks to realize a total return  consistent  with investment in
securities of companies that are engaged in mining, processing,  fabricating, or
distributing gold or other precious metals throughout the world.

     GLOBAL NATURAL  RESOURCES  seeks to realize a total return  consistent with
investment in companies that are engaged in the natural resources industries.

COMPARATIVE INDICES

     The  following  indices  are  used  in  the  report  for  fund  performance
comparisons. They are not investment products available for purchase.

     The Global Gold fund  benchmark was the Benham North American Gold Equities
Index from inception  through  February 1996.  From March 1996 through  December
1997,  the  benchmark  was the FT-SE Gold Mines Index.  From January 1998 to the
present,  the benchmark has been a proprietary index described in more detail on
page 6.

     The FT-SE(reg.tm)  GOLD MINES INDEX(1) consists of 31 gold mining companies
in five  countries  and is  considered  a broad  measure of the  worldwide  gold
equities market.

     The DOW JONES  WORLD  STOCK  INDEX(2),  created by the  editors of The Wall
Street  Journal,  consists of 2,800 stocks in 29  countries  and is divided into
nine broad  market  sectors.  We created  the Global  Natural  Resources  fund's
benchmark index using the companies  represented in two of these  sectors--Basic
Materials and Energy.  We altered the Basic Materials sector to exclude chemical
companies because they do not stockpile natural resources.

     The MORGAN  STANLEY WORLD STOCK INDEX is a widely  followed group of stocks
from 22 different countries including the U.S. and Canada.

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.

     The Lipper categories for Global Gold and Global Natural Resources are:

     GOLD-ORIENTED FUNDS (Global  Gold)--funds that invest at least 65% of their
assets in shares of gold mines,  gold-oriented mining finance houses, gold coins
or bullion.

     NATURAL  RESOURCES FUNDS (Global Natural  Resources)--funds  that invest at
least 65% of their assets in natural resources stocks.

(1)  The FT-SE Gold Mines Index is calculated by FT-SE International  Limited in
     conjunction with the Institute of Actuaries.  The FT-SE Gold Mines Index is
     a trademark of the London Stock  Exchange  Limited and the Financial  Times
     Ltd.  and is used by  FT-SE  International  Limited  under  license.  FT-SE

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 24-27.

PORTFOLIO STATISTICS

* NUMBER OF COMPANIES  --the number of different  companies  held by a fund on a
given date.

* PORTFOLIO  TURNOVER --the percentage of a fund's investment  portfolio that is
replaced during a given time period, usually a year. Actively managed portfolios
tend to have higher  turnover than passively  managed  portfolios  such as index
funds.

* 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 STOCKS

* LARGE-CAPITALIZATION (LARGE-CAP) STOCKS --generally considered to be stocks of
companies  with  a  market  capitalization  (the  total  value  of  a  company's
outstanding  stock) of more than $5  billion.  These tend to be the stocks  that
make up the Dow Jones Industrial Average and the S&P 500.

* MEDIUM-CAPITALIZATION  (MID-CAP) STOCKS --generally considered to be stocks of
companies  with  a  market  capitalization  (the  total  value  of  a  company's
outstanding  stock) of between $1 billion and $5  billion.  These tend to be the
stocks that make up the S&P MidCap 400.

* SMALL-CAPITALIZATION (SMALL-CAP) STOCKS --generally considered to be stocks of
companies  with  a  market  capitalization  (the  total  value  of  a  company's
outstanding  stock) of less than $1  billion.  These tend to be the stocks  that
make up the Russell 2000 and the S&P SmallCap 600.

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.

The investment  objective may be based on the fund's  objective as stated in its

each category can vary  significantly,  and some fund returns have  historically

Please be aware that a 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.

For a definition of fund categories, see the Glossary.

*  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.

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,  all of our computer systems have been modified,  tested and returned
to  production.  We have an ongoing  commitment  to testing our systems with our
vendors and business partners and within the industry throughout the rest of the
year.

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  to our testing  schedule,  our Y2K team has  developed  contingency
plans.  These  plans  will  minimize  the  impact on our  investors  and help us
maintain operations in the event of any Y2K-related  incidents.  We will conduct
practice  drills of  contingency  scenarios  during  the rest of 1999 and refine
those  plans 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.

MINIMIZE YOUR MUTUAL FUND TAX HIT

     American  Century's newest equity fund,  Tax-Managed Value, is designed for
long-term  growth  and to  minimize  the tax hit you  take on your  mutual  fund
investments  each year. The fund is managed to keep taxable  distributions  to a
minimum by using the following strategies:

     *  BUY AND HOLD --Low portfolio turnover helps limit realized capital gains
        and takes advantage of long-term capital gains tax rates.

     *  OFFSET GAINS --When gains are realized in the portfolio, they are offset
        with  capital  losses  from  securities  sold in that tax year or losses
        carried over from previous years.

     *  SELL HIGHER-COST  SHARES FIRST --Selling shares that cost the most first
        helps minimize the taxable gains incurred from a sale.


Our Message to You
- --------------------------------------------------------------------------------

James E. Stowers III, seated, with James E. Stowers, Jr.

     During the six months  ended  June 30,  1999,  we  witnessed  a  surprising
turnaround  in the U.S.  economic  outlook.  When we last  addressed  you in the
annual  report for American  Century  Utilities,  the Federal  Reserve (the U.S.
central bank) had recently cut short-term interest rates to bolster the U.S.
economy and help stabilize markets worldwide.

     This came after economic and financial  crises in Asia,  Russia,  and Latin
America,  and the near  collapse of several  hedge  funds.  The global  economic
outlook was still quite  uncertain -- many  financial  observers  predicted slow
economic growth in the U.S. in 1999 and further interest rate cuts.

     Instead,  global economic conditions  rebounded.  By January 1999, overseas
economies were  stabilizing,  the U.S.  economy was posting  strong growth,  and
investor  confidence  had  returned.  Interest  rates rose while the U.S.  stock
market soared.

     On the  corporate  front,  we  continued  to expand  the  American  Century
investment team, which has doubled over the past three years. We're committed to
building and maintaining a talented management group.

     We also enhanced our Web site (www.americancentury.com).  There you'll find
daily  fund   information,   news,  and  a  Forms  Center  with  access  to  the
most-requested investor forms and applications.  You can also sign up to receive
fund prospectuses and shareholder reports electronically.

     In the spirit of our ongoing Year 2000  readiness  disclosures,*  here's an
update  on our  preparations  for Y2K.  Our  senior  level  Year  2000  Steering
Committee,  computer  programmers,  business  partners,  and Y2K team  have been
working  diligently  to make January 1, 2000, a non-event  for American  Century
investors. All of our computer systems have been modified,  tested, and returned
to  production.  We have an ongoing  commitment  to  testing  our  systems  with
vendors, business partners, and the mutual fund industry through the rest of the
year.

     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.  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.

     As always, we appreciate your continued confidence in American Century.

Report Highlights
- --------------------------------------------------------------------------------

MARKET PERSPECTIVE

*   U.S. stocks performed fairly well during the six months ended June 30, 1999.
    Large-cap  stocks  continued to enjoy  above-average  gains,  while mid- and
    small-cap shares posted more historically average returns.

*   Solid  corporate  earnings  and fairly  robust  U.S.  economic  growth  kept
    investor optimism high and fueled the generally positive performance of U.S.
    stocks.  However,  it also  prompted the Federal  Reserve (the U.S.  central
    bank) to raise  short-term  interest rates on June 30 in an effort to reduce
    inflation pressures.

*   Despite higher interest rates,  utilities stocks turned in reasonably strong
    results.  Continued deregulation,  industry consolidation,  and a boost from
    the sector rotation toward energy and value stocks bolstered returns.

*   Natural  gas  and  telecommunications  were  the  top-performing   utilities
    sectors. Electric utilities lagged, stymied by rising interest rates.

MANAGEMENT Q&A

*   American  Century  Utilities'  performance for the six months ended June 30,
    1999,  lagged the  average  return of its Lipper  peer group  slightly.  The
    portfolio had less than a 5% weighting in natural gas stocks, which returned
    over 20% on average for the period.

*   The fund's  longer-term  returns  were still  attractive.  American  Century
    Utilities  ranked in the top 10 of the Lipper  utilities group for the one-,
    three-, and five-year periods ended June 30.

*   The relatively  small natural gas weighting was  consistent  with the fund's
    benchmark index, which has its heaviest weightings in telecommunications and
    electric utilities stocks.

*   Mergers, acquisitions, consolidation, and deregulation continued to be major
    themes that affected the portfolio. Merger and acquisition activity directly
    affected the performance of the fund's top four holdings as of June 30: GTE,
    Bell Atlantic, Ameritech, and SBC Communications.

*   We continue to believe that long-term  trends -- such as Internet  expansion
    and the growth of wireless communications -- should favor telecommunications
    companies.

Market Perspective from Mark Mallon
- --------------------------------------------------------------------------------

Mark Mallon, head of growth and income equity,  specialty,  and asset allocation
funds at American Century

MARKET SNAPSHOT

     U.S.  stocks  performed  fairly well  during the six months  ended June 30,
1999.  Large-cap stocks continued to enjoy  above-average  gains, while mid- and
small-cap shares posted more historically average returns. (See the accompanying
stock market  returns  table.) Solid  corporate  earnings and fairly robust U.S.
economic  growth kept investor  optimism high and fueled the generally  positive
performance for U.S. stocks.

ECONOMIC UNDERPINNINGS

     The longest economic expansion in 50 years provided the springboard for the
stock market's  continued  gains.  The remarkable  U.S.  economic engine powered
ahead at a 4.3% annual pace during the first  quarter,  accompanied by corporate
earnings  that were far  stronger  than  expected.  Improvements  in Pacific Rim
economies--where   Korea's  industrial   production  surged,   Taiwan's  leading
indicators rose, and Japan's economy showed signs of life--further  enhanced the
global economic outlook.

     The  U.S.  economy  slowed  in the  second  quarter  but  still  grew at an
estimated  2.3% annual pace.  Meanwhile,  U.S.  corporate  profits rose 16%--the
largest  quarterly gain in nearly four years. By the end of June, the three most
popular U.S. stock indices--the Dow Jones Industrial  Average,  the S&P 500, and
the Nasdaq Composite--all achieved record highs.

THE FED INTERVENES

     Economic and corporate  earnings  strength  attracted the full attention of
inflation  watchdogs,  particularly  the  Federal  Reserve  (the Fed -- the U.S.
central bank).  Just days after a May  announcement  that U.S.  consumer  prices
experienced  their biggest monthly gain in almost nine years,  the Fed announced
that its bias had shifted toward  raising  interest  rates.  On June 30, the Fed
acted upon its bias,  pushing  short-term  interest rates a quarter of a percent
higher in an effort to reduce inflation pressures.

FIRST-QUARTER STOCK RECAP:  1998 REDUX

     The dominance of large-cap  growth stocks and the narrow market  leadership
that  characterized  1998 continued into early 1999. The S&P 500 still ruled the
roost and,  according to Morgan Stanley Dean Witter,  just five stocks accounted
for half of the S&P 500's  return  during the first three months of 1999. A mere
18 accounted for the full 100%; the rest essentially canceled each other out.

     As a result,  the bellwether  growth names became  increasingly  expensive.
When the U.S. economy refused to show any signs of slowing down, investors began
to look elsewhere.

Market Perspective from Mark Mallon
- --------------------------------------------------------------------------------
                                                                    (Continued)

SECOND-QUARTER STOCK RECAP: REVENGE OF THE LAGGARDS

     Emboldened  by the global  economic  recovery,  investors  deserted the big
names and sought  attractively  priced  value and  small-company  shares.  Index
returns  tell the story -- the S&P 500/ BARRA Value Index,  a benchmark  for the
performance  of  large-cap  value  stocks,  rose  10.80% in the second  quarter,
compared  with the 3.83% return of the S&P  500/BARRA  Growth  Index.  Even more
impressive  was the  performance  of small-cap  value  shares:  the S&P SmallCap
600/BARRA  Value Index jumped  19.91%,  outpacing  the 11.11%  return of the S&P
SmallCap 600/BARRA Growth Index.

     Cyclical  stocks -- those  closely  tied to economic  ups and downs  --also
performed well during the second quarter  because of improving  global  economic
conditions.  That  allowed  shares of  aluminum,  chemicals,  construction,  and
diversified machinery companies to provide some of the quarter's better returns.
Aluminum  was also one of the better  performing  industries  for the entire six
months, as were the brokerage,  broadcast/media,  industrials, and semiconductor
industries.

THE UTILITIES MARKET

     Despite rising interest rates, utilities stocks turned in reasonably strong
results  for  the  first  half  of  1999.   Continued   deregulation,   industry
consolidation,  and a boost from the  sector  rotation  toward  energy and value
stocks bolstered returns.

     Consolidation  was  rampant.   Increasing  numbers  of  telecommunications,
electric,  and natural gas companies either announced plans to merge or actually
completed  mergers and  acquisitions  to gain footholds in new markets,  augment
existing services, and reduce costs.

TELECOM STILL STRONG IN 1999

     Merger  and  acquisition  activity  and  the  continued  explosion  in  new
technologies  drove  telecommunications   stocks  to  double-digit  returns,  on
average,  during the first half of 1999.  With  Internet  traffic  estimated  to
double about every 100 days or so, the telecommunications companies that provide
Internet access  performed  well. So did the companies that provide  "broadband"
networks  capable of  efficiently  moving data, as the demand for voice and data
connections grew. In addition, the exponential growth of wireless communications
in both the U.S. and abroad helped boost cellular companies.

NATURAL GAS REBOUNDS

     One of the biggest  surprises was the explosive  performance of natural gas
stocks,  which had lagged far behind their telecom  counterparts  in 1998.  This
sector benefited from the trends that caused value,  energy, and cyclical stocks
to rally. A brightening  global economic  picture,  favorable  supply and demand
conditions,  and merger and  acquisition  activity helped push natural gas stock
prices to unexpectedly high levels.

ELECTRIC RETURNS FLICKER

     Rising interest rates helped turn electric  utilities into the dim bulbs on
the  string.  Not even a wave of  merger  activity  helped;  investors  appeared
skeptical about the results.  Electrics  rebounded  somewhat when investors went
searching for value stocks. But renewed inflation fears in June caused electrics
to give back their earlier gains.

Utilities--Q&A
- --------------------------------------------------------------------------------
/photo of Joe Sterling, Kurt Borgwardt, and John Schniedwind/

     Based  on  interviews  with  Joe  Sterling,   Kurt   Borgwardt,   and  John
Schniedwind, portfolio managers on the Utilities fund investment team.

HOW DID THE FUND PERFORM FOR THE SIX MONTHS ENDED JUNE 30, 1999?

     American  Century  Utilities  posted a total  return  of  6.84%,*  slightly
lagging the 7.02% average total return of 101 utilities  funds tracked by Lipper
Inc.  For the one-year  period ended June 30, the results were better.  American
Century Utilities  returned 25.42%,  compared with the 16.81% average return for
the Lipper peer group.  The fund's returns placed it in the top 10 of the Lipper
utilities group for the one-, three-, and five-year periods ended June 30.

WHAT CAUSED THE DIFFERENTIAL  BETWEEN THE FUND'S RETURN AND THE LIPPER UTILITIES
AVERAGE DURING THE FIRST HALF OF 1999?

     As often happens in the  portfolio  management  business,  key factors that
boosted  performance one year caused returns to lag in the following  period. In
1998,   American  Century  Utilities  benefited  from  its  large  weighting  in
telecommunications  companies,  which  were  far and  away  the  best-performing
utilities  sector that year, and from its relatively  small stake in natural gas
stocks, which lagged far behind other sectors.

     In the first half of 1999, our small weighting in natural gas stocks (about
3% of fund assets as of June 30) hurt the  portfolio.  The S&P Natural Gas Index
returned  just  over  24%  for  the  period,  a pace  that  even  the  still-hot
telecommunications  stocks didn't match.  Rising natural gas prices,  investors'
appetite for undervalued  stocks, a rebound in stocks that stood to benefit from
global economic resurgence, and merger and acquisition activity all helped boost
natural gas stocks.

WHY WAS YOUR WEIGHTING IN NATURAL GAS STOCKS SO SMALL? HOW DO YOU DECIDE WHAT
PORTION OF THE FUND'S INVESTMENTS ARE ALLOCATED TO DIFFERENT UTILITIES SECTORS?

     Our  weighting  for natural gas stocks  wasn't  much  different  from their
weighting  in the  fund's  benchmark.  American  Century  Utilities'  investment
portfolio  tracks a custom  index of 165  utilities  stocks made up of about 55%
telephone and communications services companies,  35% electric and gas utilities
(primarily electric companies),  and about 10% utilities-related  companies such
as communications equipment manufacturers.

     The  sector  weightings  in the  custom  index  are  based  on  the  market
capitalizations  of  the  sectors.  In  other  words,  the  index  reflects  the
composition of the utilities market, weighted by the size of the companies,  not
their number.

- --------------------------------------------------------------------------------
                                                                    (Continued)

     At times,  we may under- or overweight a utilities  sector if we believe it
is  dramatically  over-  or  undervalued.  But  we  generally  keep  our  sector
weightings  pretty  close to the  benchmark.  Though  past  performance  doesn't
predict  future  results,  American  Century  Utilities'  long-term  performance
appears to have benefited from this disciplined, but growth-oriented approach.

SPEAKING OF GROWTH, TELECOMMUNICATIONS STOCKS CONTINUED TO PERFORM WELL IN THE
FIRST HALF OF 1999. WHAT WAS BEHIND THEIR STRENGTH?

     Many of the same factors  that drove the telecom  sector to high returns in
1998 remained in place. Merger and acquisition  activity was still a key factor.
During the past six months,  for example,  the proposed merger between two major
regional telephone companies -- SBC Communications and Ameritech, both among the
fund's top 10  holdings  -- moved  closer to  becoming  reality.  Likewise,  the
proposed  merger  between  Bell  Atlantic and GTE -- two more top 10 holdings --
continued to advance.

     Besides the merger and acquisition activity, telecommunications stocks were
boosted by the increased  need for voice and  computer-data  transmissions,  the
growth of wireless  communication,  and the expansion of electronic commerce via
the Internet.

WHAT OTHER TELECOM COMPANIES WERE LEADERS DURING THE PAST SIX MONTHS?

     Mexico's largest telephone company, Telefonos de Mexico (Telmex), continued
to post strong earnings despite increased competition from foreign carriers. Its
stock received an added boost from investors' renewed interest in Latin American
stocks. BCE, the parent company of Bell Canada, rallied in response to increased
revenues stemming from growth in its local and access services.

     But not all of our telecommunications  stocks performed well. MCI WorldCom,
for example,  suffered substantial losses on news that it was being investigated
by the  SEC  for  allegedly  misleading  investors  in  its  pursuit  of  Skytel
Communications.

HOW DID THE FUND'S ELECTRIC  UTILITIES  HOLDINGS (ABOUT 30% OF FUND ASSETS AS OF
JUNE 30) PERFORM?

     Electric  utilities stocks proved to be somewhat  disappointing,  primarily
because of rising  interest  rates.  However,  we  continued to maintain a large
position in electrics, in part because we think they are attractively priced. At
the end of June,  electric  utilities  were valued at about 50% of the S&P 500's
price-to-earnings  multiple,  much cheaper than their historic  average of about
70%.

     In  addition,  we  believe  that  continued  deregulation  of the  electric
industry will fuel future merger and acquisition  activity,  a development  that
would most likely boost the sector's longer-term performance.

WHAT'S YOUR OUTLOOK FOR UTILITIES STOCKS IN GENERAL?

     We think that  long-term  trends  favor this  sector.  As we've  mentioned,
deregulation  -- which is responsible  for much of the sector's gains during the
past  several  years  --  should  continue  to  provide  favorable   longer-term
underpinnings for the telecommunications,  electric, and natural gas industries.
But we wouldn't be surprised if the road toward further deregulation  encounters
a  regulatory  bump or two  along  the way,  which  may  cause  some  occasional
challenges for the group.

     Focusing  on our  largest  weighting,  we believe  that  telecommunications
companies will post attractive growth rates. Rapid changes in technology seem to
be continually  transforming the way we use voice and data  communications.  The
Internet,  for example, is exploding as a means of communication and has emerged
as an  important  avenue  for  electronic  commerce.  Meanwhile,  the  worldwide
expansion  of  wireless  phone  service  marches   forward.   Telecommunications
companies lie at the center of this revolution.

     We're  also  upbeat  about  the   prospects   in  other  areas.   Continued
consolidation  should pave the way for  electric  and natural gas  companies  to
reduce costs and add and expand services.

WON'T THE POSSIBILITY OF HIGHER INTEREST RATES CRIMP THE OUTLOOK FOR UTILITIES
STOCKS?

     In the short run, yes. But if rising  interest rates  eventually lead to an
economic slowdown,  utilities stocks,  particularly  electric  utilities,  could
benefit.  Economic  weakness  typically  throws a  spotlight  on the  relatively
reliable earnings of telephone,  electric, and natural gas service providers. In
addition,  a slower  economy  should  eventually  cause  interest rates to fall,
causing  bonds,  and  bond-like  securities  such as  dividend-paying  utilities
stocks, to rally.

     Unfortunately,  some  companies in the  telecommunications  sector are more
sensitive  to the  economy's  ups and downs  than  electric,  natural  gas,  and
telephone  companies.  Those telecom companies would face more challenges from a
decline in the business  cycle.  But those are the same  companies that give the
portfolio much of its upside when economic conditions are strong.

WITH ALL  THOSE  FACTORS  IN MIND,  HOW DO YOU PLAN TO MANAGE  AMERICAN  CENTURY
UTILITIES DURING THE REMAINDER OF THE YEAR?

     We plan to continue  seeking a combination  of current income and long-term
growth of  capital  and  income.  The  utilities  sector has  undergone  a major
transformation during the past 10 years, shedding its somewhat stodgy reputation
as a  reliable  dividend  producer  and  emerging  as one of the stock  market's
fastest-growing  sectors.  We try to harness  the best of both of those  worlds,
investing  in a mix of  attractively  priced  utilities  stocks that pay healthy
dividends as well as those that offer the potential for growth.

     We're   comfortable   with  the  portfolio's   current   allocation   among
telecommunications, electric, and natural gas stocks and will likely continue to
keep it in line with the funds' benchmark.  As always, we intend to remain fully
invested in utilities stocks so the fund's  performance will continue to reflect
the dynamics of the utilities sector.

UNDERSTANDING  THE STATEMENT OF ASSETS AND  LIABILITIES--This  statement details
what the fund owns (assets),  what it owes (liabilities),  and its net assets as
of the last day of the period.  If you subtract  what the fund owes from what it
owns,  you get the fund's net assets.  For each class of shares,  the net assets
divided  by the total  number of  shares  outstanding  gives you the price of an
individual share, or the net asset value per share.

NET ASSETS are also broken down by capital (money invested by shareholders); net
investment  income not yet paid to  shareholders or net investment  losses;  net
gains earned on investments  but not yet paid to  shareholders  or net losses on
investments (known as realized gains or losses); and finally, gains or losses on
securities  still  owned  by the  fund  (known  as  unrealized  appreciation  or
depreciation).  This  breakdown  tells  you the  value  of net  assets  that are
performance-related,  such as investment  gains or losses,  and the value of net
assets that are not related to performance,  such as shareholder investments and
redemptions.

Notes to Financial Statements
- --------------------------------------------------------------------------------

JUNE 30, 1999 (UNAUDITED)

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION -- American Century Quantitative Equity Funds (the corporation)
is  registered  under  the  Investment  Company  Act  of  1940  as  an  open-end
diversified  management investment company.  Utilities Fund (the fund) is one of
the six funds  issued by the  corporation.  The fund  seeks  current  income and
long-term  growth of capital and income.  The fund  invests  primarily in equity
securities  of  companies  engaged  in  the  utilities  industry.  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 -- Portfolio  securities traded primarily on a principal
securities  exchange are valued at the last reported sales price, or the mean of
the latest bid and asked  prices where no sales price is  available.  Securities
traded  over-the-counter  are  valued  at the mean of the  latest  bid and asked
prices or, in the case of certain foreign securities, at the last reported sales
price,  depending on local  convention or  regulation.  When  valuations are not
readily  available,  securities  are  valued  at fair  value  as  determined  in
accordance with procedures adopted by the Board of Directors.

    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 -- Dividend income less foreign taxes withheld (if any) is
recorded as of the ex-dividend date.  Interest income is recorded on the accrual
basis and includes accretion of discounts and amortization of premiums.

    REPURCHASE  AGREEMENTS -- The fund may enter into repurchase agreements with
institutions that the fund's  investment  manager,  American Century  Investment
Management,  Inc. (ACIM),  has determined are creditworthy  pursuant to criteria
adopted by the Board of  Directors.  Each  repurchase  agreement  is recorded at
cost. The fund requires that the collateral, represented by securities, received
in a  repurchase  transaction  be  transferred  to  the  custodian  in a  manner
sufficient  to enable  the fund to  obtain  those  securities  in the event of a
default under the repurchase  agreement.  ACIM monitors,  on a daily basis,  the
securities  transferred to ensure the value,  including accrued interest, of the
securities  under each repurchase  agreement is greater than amounts owed to the
fund under each repurchase agreement.

    JOINT  TRADING  ACCOUNT --  Pursuant  to an  Exemptive  Order  issued by the
Securities  and  Exchange  Commission,  the fund,  along with  other  registered
investment  companies  having  management  agreements  with ACIM,  may  transfer
uninvested  cash  balances  into a joint  trading  account.  These  balances are
invested in one or more repurchase agreements that are collateralized by U.S.
Treasury and Agency obligations.

    INCOME  TAX  STATUS  -- It is  the  fund's  policy  to  distribute  all  net
investment  income  and net  realized  gains to  shareholders  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  TO SHAREHOLDERS -- Distributions to shareholders are recorded
on the ex-dividend date.  Distributions  from net investment income are declared
and paid  quarterly.  Distributions  from net realized  gains are expected to be
declared and paid annually.

     The  character of  distributions  made during the year from net  investment
income or net realized gains may differ from their ultimate characterization for
federal income tax purposes.  These differences  reflect the differing character
of  certain  income  items and net  realized  gains  and  losses  for  financial
statement  and tax purposes  and may result in  reclassification  among  certain
capital accounts.

    ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is the corporation's
distributor. Certain officers of FDI are also officers of the corporation.

- --------------------------------------------------------------------------------
2.  TRANSACTIONS WITH RELATED PARTIES

    The  corporation  has entered into a Management  Agreement with 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  commissions,  taxes,  portfolio
insurance,  interest,  fees and expenses of the Directors 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 0.3380% to
0.5200% 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 June 30, 1999,  the effective  annual  Investor
Class management fee was 0.68%.

    The Board of Directors 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  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 by
the fund under the plan for the six months ended June 30, 1999 were $3,538.

    Certain  officers and directors of the  corporation are also officers and/or

Share Class and Retirement Account Information
- --------------------------------------------------------------------------------

SHARE CLASSES

     Two classes of shares are authorized for sale by the funds: 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
is 0.25% higher than the total expense ratio of the Investor Class.

     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)]
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 tax 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 four  "specialty"  equity funds* that  concentrate
their  holdings in specific  industries  or sectors of the stock  market.  These
funds typically respond differently than general equity funds to changing market
or economic conditions.  The funds are managed to provide a broad representation
of their respective industries.

     AMERICAN  CENTURY  UTILITIES  seeks current income and long-term  growth of
capital  and  income.  The fund  invests  primarily  in the stocks of  companies
engaged in the  utilities  industry,  including  electricity,  natural  gas, and
telecommunications services.

COMPARATIVE INDICES

     The  following  indices  are  used  in  the  report  for  fund  performance
comparisons. They are not investment products available for purchase.

     The  S&P  500  is a  capitalization-weighted  index  of the  stocks  of 500
publicly traded large-capitalization companies that are considered to be leading
firms in leading industries. Created by Standard & Poor's Corporation, the index
is viewed as a broad measure of U.S. stock market performance.

     The S&P MIDCAP 400 is composed of 400  mid-capitalization  stocks traded on
domestic  exchanges.  It is  considered  a  broad  measure  of  mid-sized  stock
performance.

     The S&P SMALLCAP 600 is composed of 600 small-capitalization  stocks traded
on domestic  exchanges.  It is considered a broad measure of small-company stock
performance.

     The FUND BENCHMARK consists of approximately 165 utilities stocks that meet
the fund's investment criteria. The benchmark's composition by industry group in
1998 was approximately 55% telephone and  communication  services,  35% electric
and  natural  gas  companies,  and  10%  utilities-related  companies,  such  as
manufacturers of communications equipment.

     The S&P ELECTRIC  INDEX is composed of 26 electric  power  companies in the
S&P 500.

     The S&P NATURAL GAS INDEX is  composed of 11 natural gas  distributors  and
pipeline companies in the S&P 500.

     The S&P  TELECOMMUNICATIONS  (LONG  DISTANCE)  INDEX  is  composed  of four
long-distance telephone companies in the S&P 500.

     The S&P TELEPHONE INDEX is composed of nine regional telephone companies in
the S&P 500.

LIPPER RANKINGS

     LIPPER INC. is an independent mutual fund ranking service that groups funds
according to their  investment  objective.  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.

     Lipper's UTILITY FUNDS category  consists of funds that invest at least 65%
of their portfolios in utilities stocks.

* Investing  in  these  funds  involves   special  risks  resulting  from  their
  concentrated  investment  objectives.  They  are not  intended  to  serve as a
  complete investment program by themselves.

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 total returns,  please refer to the "Financial
Highlights" on pages 17-18.

PORTFOLIO STATISTICS

* NUMBER OF COMPANIES --the number of different  companies held by the fund on a
given date.

* 30-DAY  SEC YIELD  --net  investment  income  earned by the fund over a 30-day
period,  expressed as an annual  percentage rate based on the fund's share price
at the end of the 30-day period. The SEC yield should be regarded as an estimate
of the fund's  dividend  income,  and it may not equal the fund's  actual income
distribution  rate, the income paid to a  shareholder's  account,  or the income
reported in the fund's financial statements.

* PRICE/EARNINGS (P/E) RATIO --a stock value measurement  calculated by dividing
a company's stock price by its earnings per share,  with the result expressed as
a multiple  instead of as a  percentage.  (Earnings  per share is  calculated by
dividing the after-tax earnings of a corporation by its outstanding shares.)

* PORTFOLIO TURNOVER--the  percentage of the fund's investment portfolio that is
replaced during a given time period, usually a year. Actively managed portfolios
tend to have higher  turnover than passively  managed  portfolios  such as index
funds.

* 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 STOCKS

* BLUE  CHIP  STOCKS -- stocks of the most  established  companies  in  American
industry.   They  are  generally  large,   fairly  stable  companies  that  have
demonstrated consistent earnings and usually have long-term growth potential.
Examples include General Electric and Coca-Cola.

* CYCLICAL STOCKS -- generally  considered to be stocks whose price and earnings
fluctuations  tend to follow the ups and downs of the business  cycle.  Examples
include the stocks of automobile  manufacturers,  steel  producers,  and textile
operators.

* GROWTH  STOCKS --  stocks of  companies  that have  experienced  above-average
earnings  growth and appear likely to continue  such growth.  These stocks often
sell at  high  P/E  ratios.  Examples  can  include  the  stocks  of  high-tech,
healthcare, and consumer staple companies.

* LARGE-CAPITALIZATION (LARGE-CAP) STOCKS --generally considered to be stocks of
larger-sized companies that make up the Dow Jones Industrial Average and the S&P
500.

* MEDIUM-CAPITALIZATION  (MID-CAP) STOCKS --generally considered to be stocks of
mid-sized companies that make up the S&P MidCap 400.

* SMALL-CAPITALIZATION (SMALL-CAP) STOCKS --generally considered to be stocks of
smaller-sized companies that make up the Russell 2000 and the S&P SmallCap 600.

* VALUE STOCKS -- generally  considered to be stocks that are purchased  because
they are relatively inexpensive. These stocks are typically characterized by low
P/E ratios.

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.

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.

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 a 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.

For a definition of fund categories, see the Glossary.

*  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.

Please call  1-800-345-2021  for a prospectus or profile on any American Century
fund.  These  documents  contain  important  information  including  charges and
expenses, and you should read them carefully before you invest or send money.
