A Note from the Founder
- -----------------------

     On our 40th  anniversary,  I would  personally  like to express my profound
appreciation  for the  confidence  you have shown in  American  Century.  We are
grateful for the opportunity to manage your money,  and we will do our utmost to
continue to meet your expectations and justify your confidence in us.

     I  founded  American  Century  on  the  belief  that  if we  can  make  you
successful,  you, in tern,  will make us successful.  That is the principle that
will guide us in the future.

     Sincerely,
     /s/James E. Stowers


About our New Report Design
- ---------------------------

Why We Changed

     We're trying hard to be reader-friendly.  Our reports contain a lot of very
good  information,  from  fund  statistics  and  financials  to Q&A's  with fund
managers.  We hope the new design will make the  reports  more  interesting  and
understandable,  while  helping  you keep  abreast of your fund's  strategy  and
performance.

What's New

     The reports are designed to be  attractive  and easy to use whether  you're
reading them in depth or just skimming.

     New features include:

     *  Larger type size in many sections.
     *  Brief explanations of the financial statements.
     *  More prominent graphs and charts.
     *  Quotes in the margins to highlight report content.

The Bottom Line

     The  new  design  actually  costs  slightly  less  than  the  old  one.  We
reallocated costs and eliminated a cover letter and the envelope that previously
came with your report enclosed. This not only saves money but reduces the number
of mailing pieces you receive.

     The new reports  also use roughly the same amount of paper as the old ones.
Previously,  paper was trimmed  and thrown  away to produce  the smaller  report
size.

     We believe  we've come up with a more  interesting,  informative  and user-
friendly publication.

     We hope you enjoy it.

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


     In general,  the global  financial  markets  performed  well during the six
months ended May 31, 1998. The U.S. stock market maintained its upward momentum,
U.S. bond yields hit record lows, and European stocks soared.  The solid returns
of our Strategic Asset  Allocation  funds during the six-month  period reflected
this environment.

     But areas of concern also appeared. Asian markets continued to suffer under
the weight of a serious  financial  crisis.  The  effects of the Asian  economic
turmoil began to spread to the rest of the world's economies and produced weaker
earnings at many U.S. corporations.

     The uncertain market  conditions  reinforce the importance of a diversified
investment portfolio. By holding a mix of domestic and foreign stocks, bonds and
money  market  funds,  you can cushion your  portfolio  against the effects of a
decline in any single investment.

     The Strategic Asset Allocation funds were designed to give you this kind of
diversification  in a single  investment.  But even if these  three  funds don't
match  your  needs  exactly,  they can still be useful as a base  investment  in
building your own diversified portfolio.

     For example,  a younger  investor  willing to accept more volatility to get
higher returns might combine our Aggressive  portfolio with an aggressive growth
stock fund and an international stock fund. Or an older investor might divide an
investment between our Conservative  portfolio,  an intermediate-term  bond fund
and a money market fund to emphasize dividend income and capital preservation.

     If you'd  like to learn  more  about  diversification  or other  investment
topics, we have a wealth of free educational brochures and booklets available by
mail.   You  can   also   get   educational   information   on  our   Web   site
(www.americancentury.com).  We've  recently  added  several new  features to the
site, including retirement investing calculators and online investment tracking.
We're  committed to making your  relationship  with us as easy and productive as
possible.

     We appreciate your investment with American Century.

Sincerely,

/s/James E. Stowers, Jr.                  /s/James E. Stowers III

Report Highlights
- -----------------------------------------------------------------------------
MARKET PERSPECTIVE

*  The  continuing  financial  crisis in Asia  contributed  to slowing  economic
   growth and low inflation worldwide.

*  Favorable economic conditions and heavy cash flows boosted U.S. stock returns

*  Among foreign stocks,  European markets provided the best investment returns,
   while Asian stocks struggled.

*  Domestic bonds were relatively  stable,  but low inflation and strong foreign
   demand led to positive returns overall.

STRATEGIC ALLOCATION: CONSERVATIVE

*  For the six months  ended May 31,  1998,  the fund's  return was in line with
   that of its benchmark (a mix of eight market indices).

*  We made few  changes  to  Strategic  Conservative's  asset mix;  instead,  we
   focused on making adjustments within each asset class:

   *  U.S. bonds--reduced holdings of Treasury bonds and added government agency
      and asset-backed securities.

   *  U.S.  stocks--began to shift from  value-oriented  stocks to large-company
      growth stocks.

   *  Foreign stocks--virtually  eliminated Asia and invested double our neutral
      weighting in Europe.

*  Going forward, we plan to take a more defensive position by modestly reducing
   our U.S. stock holdings and adding to our U.S. bonds and cash.

STRATEGIC ALLOCATION: MODERATE

*  For the six months  ended May 31,  1998,  the fund's  return beat that of its
   benchmark (a mix of 10 market indices).

*  We made few changes to Strategic Moderate's asset mix; instead, we focused on
   making adjustments within each asset class:

   *  U.S.  stocks--began to shift from  value-oriented  stocks to large-company
      growth stocks.

   *  U.S. bonds--reduced holdings of Treasury bonds and added government agency
      and asset-backed securities.

   *  Foreign stocks--virtually  eliminated Asia and invested double our neutral
      weighting in Europe.

   *  Going  forward,  we plan to take a more  defensive  position  by  modestly
      reducing our U.S. stock holdings and adding to our U.S. bonds and cash.

STRATEGIC ALLOCATION: AGGRESSIVE

*  For the six months  ended May 31,  1998,  the fund's  return beat that of its
   benchmark (a mix of 11 market indices).

*  We made few changes to Strategic  Aggressive's asset mix; instead, we focused
   on making adjustments within each asset class:

   *  U.S.  stocks--began to shift from  value-oriented  stocks to large-company
      growth stocks.

   *  Foreign stocks--virtually  eliminated Asia and invested double our neutral
      weighting in Europe.

   *  U.S. bonds--reduced holdings of Treasury bonds and added government agency
      and asset-backed securities.

*  Going forward, we plan to take a more defensive position by modestly reducing
   our U.S. stock holdings and adding to our U.S. bonds and cash.

Market Perspective with Jeff Tyler

SPOTLIGHT ON ASIA

     During the six months ended May 31, 1998,  the theme  permeating the global
stock and bond  markets was the  financial  meltdown  in Asia.  In  mid-1997,  a
currency  crisis among  Southeast  Asian  countries  pushed their economies into
recession  and sent their  financial  markets  into  freefall.  Since then,  the
effects of this crisis have had a growing impact on the rest of the world:

*    SLOWER  GLOBAL  ECONOMIC  GROWTH--a  lack of  consumer  demand  in Asia has
     reduced  economic  activity  in many  countries  that export to the region.
     Although  the U.S.  economy  has held up so far,  countries  as  diverse as
     Brazil and Italy have seen dramatic economic slowdowns.

*    LOW WORLDWIDE  INFLATION--in  an effort to rebuild their  economies,  Asian
     countries have cut prices on their  exports.  This has weakened the pricing
     power of companies  elsewhere  in the world and kept global  inflation to a
     minimum.

*    FALLING COMMODITIES  PRICES--weak demand from Asia has pushed the prices of
     raw  materials  (such as oil,  gold and grains)  substantially  lower.  The
     Goldman Sachs Commodities Index, a broad index of commodities  prices, fell
     more than 30% during the six-month period.

     We expect Asia's economic, political and social health to remain factors in
the performance of the global financial markets for the foreseeable future.

U.S. STOCKS

     Between  1995 and  1997,  the U.S.  stock  market  enjoyed  one of the best
three-year  performance  periods in its history.  This was  especially  true for
large-company  stock indices like the S&P 500,  which  returned more than 20% in
each of the three  calendar  years.  During the six months ended May 31, the S&P
500 barely  paused to catch its  breath,  gaining  just over 15%.  Small-company
stocks,  represented  by the Russell 2000,  trailed  large-cap  stocks but still
posted solid returns (see the accompanying table).

     Why did U.S. stocks perform so well?  Economic  conditions  remained ideal,
with  robust  growth and  minimal  inflation.  Low  interest  rates  helped keep
corporate  borrowing  expenses down and made bonds a less attractive  investment
alternative to stocks. Given this generally positive business climate,  it's not
surprising that cash continued to flow heavily into stocks.

     Merger activity also benefited the stock market.  Most significant were the
"megamergers" among large banks and financial companies,  but other high-profile
mergers in the media,  telecommunications  and automobile industries helped lift
the market as a whole.

     Although U.S. stocks performed well, weaker corporate  earnings--a casualty
of the fallout from Asia--led to increased market volatility late in the period.
In the first  quarter of 1998,  the  earnings  of the  companies  in the S&P 500
declined by about 2% compared  with the first quarter of 1997. In April and May,
when first-quarter  earnings were reported, the S&P 500 dropped by 1%, while the
Russell 2000 slipped 5%.

Market Perspective with Jeff Tyler
- -----------------------------------------------------------------------------
                                                                    (Continued)
FOREIGN STOCKS

     As the table on page 3  illustrates,  foreign  stocks  provided some of the
best  returns in the world during the  six-month  period.  However,  there was a
great deal of regional disparity. The Morgan Stanley Europe index returned about
30%, while the Morgan Stanley Far East index posted an 11% decline.

     Asian  markets  continued  to struggle  amid  efforts to recover from their
financial problems. Japan is in recession, manufacturing output in the region is
down substantially, and consumer spending has virtually disappeared.

     In  contrast,  there has been a powerful  bull market in Europe for several
years now. Low interest  rates have sparked  solid  economic  growth  across the
Continent.  On the corporate  front,  European  businesses  are improving  their
accounting standards, consolidating to cut costs, and competing globally.

     Another  positive  factor is the onset of economic and monetary union (EMU)
in 1999.  Eleven  European  countries will join together under a common currency
and a single  central bank.  EMU has already made it easier and cheaper for many
European companies to do business throughout the union.

U.S. BONDS

     Although  fixed-income  securities  posted  favorable  returns  during  the
six-month period (see the accompanying  table),  the U.S. bond market was fairly
stable overall.  The 30-year Treasury bond yield experienced its  least-volatile
six-month  period since 1979,  fluctuating  between  6.14% and 5.69% (the lowest
yield since the late '70s).

     Despite strong U.S. economic growth and evidence of increasing labor costs,
bond yields fell and prices rose throughout much of the period.  Several factors
favored bonds:

*    Inflation  remained  low,  rising  at an  annual  rate of just 1.4% for the
     six-month period.

*    The federal budget deficit  narrowed,  reducing the government's  borrowing
     needs.  The  Treasury  cut back its debt  issuance,  and the  lower  supply
     boosted bond prices.

*    Demand  increased for U.S.  bonds as a "safe haven" from Asian markets and,
     to a lesser extent, domestic stock market volatility.

*    The Federal Reserve held short-term interest rates steady.

     The Fed didn't act because  higher  rates  would make U.S.  bonds even more
attractive to foreign investors,  which would further strengthen the U.S. dollar
and make it harder for Asia to recover.  The bond market  knows  this--over  the
past three  months,  U.S.  Treasury  bond prices have moved in lockstep with the
dollar's value against the Japanese yen.

     Treasury  securities,  especially  those  with  long  maturities,  were the
best-performing  fixed-income  sector during the period.  Corporate bonds, which
saw increased  supply as businesses took advantage of historically  low interest
rates,  trailed Treasurys.  Mortgage-backed  securities struggled with increased
refinancing activity.

FOREIGN BONDS

     Overseas bond markets  benefited from low inflation around the globe.  They
provided returns on par with U.S. bonds,  though the strong dollar reduced those
returns somewhat (see the table).

     Interest  rates in Europe  continued  to  converge  as EMU moved  closer to
becoming  a  reality.  Rates in  countries  like  Italy and  Spain,  which  have
traditionally  been higher than in other European nations,  have fallen over the
past couple of years, producing healthy bond returns.

Strategic Conservative--Q&A
- -----------------------------------------------------------------------------

     An interview  with Jeff Tyler and Brian Howell,  portfolio  managers on the
American Century Strategic Asset Allocation funds management team.

HOW DID THE STRATEGIC CONSERVATIVE FUND PERFORM?

     For the six months ended May 31,  1998,  the fund's  Investor  Class shares
posted a total return of 7.49%, compared with the 7.58% return of its benchmark.
(See the Total  Returns  table on the previous  page for other fund  performance
comparisons.)

WHAT IS THE FUND'S BENCHMARK?

     It's a combination  of eight  different  market  indices--four  U.S.  stock
indices,  one foreign stock index,  one U.S. bond index, one foreign bond index,
and one money market index. These indices represent the various asset classes in
which the fund invests and are weighted to match the fund's neutral asset mix.

     Strategic  Conservative  slightly  underperformed  its  benchmark,   mainly
because  of its U.S.  stock  holdings.  We got great  returns  from our  foreign
stocks, but they made up less than 10% of the portfolio.

DID YOU MAKE ANY CHANGES TO THE ASSET MIX OVER THE PAST SIX MONTHS?

     We kept the  portfolio  pretty  close to its neutral mix of 45% bonds,  40%
stocks,  15% cash. But stocks  outperformed bonds and cash during the period, so
we did some minor  rebalancing.  We sold some  stocks in April and  shifted  the
proceeds into bonds and money market securities to maintain neutral weightings.

     Instead of making significant  changes to the asset mix, we concentrated on
making adjustments within each asset class to try to enhance performance.

THE FUND'S BIGGEST HOLDING IS U.S. BONDS.  WHAT ADJUSTMENTS DID YOU MAKE TO THIS
PORTION OF THE PORTFOLIO?

     We cut back our Treasury  holdings quite a bit as their yields hit all-time
lows.  In their place,  we added some  callable  government  agency  securities.
Callable securities tend to offer higher yields because they can be redeemed--or
called--by the issuer before the maturity date.

     Calling a bond is kind of like refinancing a home  mortgage--when  interest
rates fall significantly, homeowners can often reduce their interest payments by
taking out a new mortgage  and paying off the old one.  Bond issuers do the same
thing with callable  bonds when rates  decline.  But interest  rates were fairly
stable during the past six months,  so there wasn't any incentive for issuers to
call these  bonds.  As a result,  the fund got some extra yield with very little
risk of a call.

     We also bought more  asset-backed  securities,  including  bonds  backed by
commercial   mortgages  and  home-equity   loans.   These  bonds  added  greater
diversification to the fund's fixed-income holdings. We purchased them when they
were more  attractively  priced than most corporate  bonds,  and they have since
performed better than corporates.

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

WHAT ABOUT THE FUND'S EQUITY HOLDINGS?

     Late in the period,  we began moving away from  value-oriented  U.S. stocks
toward  an  emphasis  on  large-company  growth  stocks.  This  was a  difficult
decision,  because there are a lot of very attractive values among the stocks of
small- and  mid-sized  companies.  However,  when  corporate  earnings  start to
weaken--as they have  recently--investors tend to gravitate toward large-company
stocks with relatively consistent growth and earnings.

     We also looked for companies that rely on domestic  consumer demand. A good
example is Home Depot,  which is a chain of retail  stores  that sells  building
materials and home improvement products. Home Depot's customers are in the U.S.,
where  economic  conditions are favorable and consumer  demand is healthy.  As a
result,  the  drop-off  in  demand  from Asia  hasn't  negatively  affected  the
company's sales.

     If anything,  Asia has had a positive effect on Home Depot's business--some
of the  products  the  company  sells are  produced  in Asia,  so its stores are
getting these products at cheaper prices.  It's not surprising that Home Depot's
stock returned more than 40% during the six-month period.

HOW HAS ASIA INFLUENCED YOUR FOREIGN INVESTMENTS?

     We've  virtually  eliminated Asia from our foreign stock portfolio (see the
chart on this page). In contrast,  we are almost double our neutral weighting in
Europe.  European equity returns were among the best in the world, so this shift
definitely added to the fund's returns.  However, foreign stocks make up a small
part of Strategic Conservative's overall portfolio.

LOOKING AHEAD, WHAT ARE YOUR PLANS FOR THE FUND'S ASSET ALLOCATION STRUCTURE?

     We intend to position the portfolio more  defensively in the coming months.
With U.S.  stock market  indices at or near all-time  highs and U.S. bond yields
close to record lows, we think it makes sense to be a little cautious.

     For the Strategic Conservative fund, this means cutting back on U.S. stocks
and shifting into U.S.  bonds and cash. We believe that bonds have better return
potential than stocks for the second half of 1998.

WHAT MAKES BONDS MORE ATTRACTIVE THAN STOCKS?

     It comes down to whether you think the high stock prices or low bond yields
are sustainable  going forward.  For bonds,  the reasons behind the low interest
rate environment are a lack of inflation and the financial crisis in Asia. These
situations  aren't  likely to change in the next six  months--it  will be awhile
before Asia solves its economic problems,  and in the meantime,  expectations of
low  commodities  prices and cheap  exports  from Asia  should  help keep global
inflation low.

Strategic Conservative--Q&A
- -----------------------------------------------------------------------------
                                                                    (Continued)

     The stock market rally,  on the other hand, has been dependent on a healthy
U.S. economy and solid corporate earnings growth.  Corporate profits are already
lower than they were a year ago, and we expect them to remain lackluster through
the end of this year. In addition,  a big build-up of  inventories  in the first
quarter and weak consumer demand from Asia will probably slow the economy.

     The bottom line is that we see more  downside risk in stocks than in bonds.
And even if both  markets  go  sideways  for the rest of the year,  bonds  offer
interest  rates  of 5-6% a year,  whereas  stocks  pay  out  dividends  of 2% or
less--if they pay any at all.

ARE YOU PLANNING TO SHIFT SIGNIFICANTLY OUT OF U.S. STOCKS?

     No.  The  adjustments  I'm  talking  about are  likely to be fairly  small.
Strategic  Conservative is managed to maintain a specific strategic position, so
we don't  stray too far from its neutral  asset mix.  To make sure of this,  the
fund's  prospectus  includes  operating  ranges for each asset class that we are
obligated to stay within. For example,  our neutral weighting for stocks is 40%,
and we must keep it between 34% and 46%.

ARE THERE STILL GOOD INVESTMENT OPPORTUNITIES OVERSEAS?

     Definitely. Europe is still a great place to invest, especially for stocks,
as privatization and productivity improvements sweep the Continent. Unemployment
remains an issue,  and it might get worse before it gets better as companies cut
costs and become more  efficient.  But if Europe  continues  along the same path
that the U.S.  started on five years ago, the region will likely have  healthier
economies and lower unemployment down the road.

     Asia, on the other hand, is not yet a buying opportunity. Japan still needs
to address its banking  crisis,  economic  woes, and growing  government  budget
deficit.  Until Japan  starts to make some  progress,  the rest of Asia won't be
able to fully recover from its own problems.

     As a result,  we plan to maintain at least a neutral  weighting  in foreign
stocks and continue our concentration in Europe.

Forward foreign currency exchange contracts are used by the portfolio management
team in an effort to protect  foreign  investments  against  declines in foreign
currencies.  This is also known as hedging.  The contracts are called  "forward"
because they allow your fund to exchange a foreign  currency for U.S. dollars at
a date in the  future--and  at a price (known as the exchange  rate) agreed upon
when the contract is initially entered into.

Strategic Moderate--Q&A
- --------------------------------------------------------------------------------

     An interview  with Jeff Tyler and Brian Howell,  portfolio  managers on the
American Century Strategic Asset Allocation funds management team.

HOW DID THE STRATEGIC MODERATE FUND PERFORM?

     For the six months ended May 31,  1998,  the fund's  Investor  Class shares
posted  a total  return  of  10.71%,  compared  with  the  8.54%  return  of its
benchmark.  (See the Total  Returns  table on the  previous  page for other fund
performance comparisons.)

WHAT IS THE FUND'S BENCHMARK?

     It's a combination of 10 different market indices--four U.S. stock indices,
two foreign stock indices,  two U.S. bond indices,  one foreign bond index,  and
one money market  index.  These  indices  represent the various asset classes in
which the fund invests and are weighted to match the fund's neutral asset mix.

     Strategic Moderate beat its benchmark during the period,  mainly because of
the significant outperformance of its foreign stock holdings.

WHY DID YOUR FOREIGN STOCKS DO SO WELL?

     Asia was the main difference. We virtually eliminated Asian stocks from our
foreign  stock  portfolio,  and we are almost  double our neutral  weighting  in
Europe (see the chart on page 22). In contrast, Asia is more than a third of the
foreign stock portion of the benchmark.

     Asian stock  market  performance  was a  disaster,  while  European  equity
returns were among the best in the world,  with many countries  returning better
than 30% during the six-month period. Even though foreign stocks are just 15% of
the portfolio, our shift into Europe added substantially to returns.

DID YOU MAKE ANY CHANGES TO THE ASSET MIX OVER THE PAST SIX MONTHS?

     We kept the  portfolio  pretty close to its neutral mix of 60% stocks,  30%
bonds, 10% cash. But stocks outperformed bonds and cash during the period, so we
did some  minor  rebalancing.  We sold  some  stocks in April  and  shifted  the
proceeds into bonds and money market securities to maintain neutral weightings.

     Instead of making significant  changes to the asset mix, we concentrated on
making  adjustments within each asset class to try to enhance  performance.  Our
shift into European stocks is one example of this approach.

THE FUND'S BIGGEST HOLDING IS U.S. STOCKS. WHAT ADJUSTMENTS DID YOU MAKE TO THIS
PORTION OF THE PORTFOLIO?

     We began moving away from smaller, value-oriented stocks toward an emphasis
on large-company growth stocks. This was a difficult decision, because there are
a lot of very  attractive  values  among  the  stocks of  small-  and  mid-sized
companies.  However,  when  corporate  earnings  start to  weaken--as  they have
recently--investors   tend  to  gravitate  toward   large-company   stocks  with
relatively consistent growth and earnings.

     We also looked for companies that rely on domestic  consumer demand. A good
example is Home Depot, which is a chain of retail stores that sells building

materials and home improvement products. Home Depot's customers are in the U.S.,
where  economic  conditions are favorable and consumer  demand is healthy.  As a
result,  the  drop-off  in  demand  from Asia  hasn't  negatively  affected  the
company's sales.

     If anything,  Asia has had a positive effect on Home Depot's business--some
of the  products  the  company  sells are  produced  in Asia,  so its stores are
getting these products at cheaper prices.  It's not surprising that Home Depot's
stock returned more than 40% during the six-month period.

WHAT ABOUT THE FUND'S U.S. BOND HOLDINGS?

     We cut back our Treasury  holdings quite a bit as their yields hit all-time
lows.  In their place,  we added some  callable  government  agency  securities.
Callable securities tend to offer higher yields because they can be redeemed--or
called--by the issuer before the maturity date.

     Calling a bond is kind of like refinancing a home  mortgage--when  interest
rates fall significantly, homeowners can often reduce their interest payments by
taking out a new mortgage  and paying off the old one.  Bond issuers do the same
thing with callable  bonds when rates  decline.  But interest  rates were fairly
stable during the past six months,  so there wasn't any incentive for issuers to
call these  bonds.  As a result,  the fund got some extra yield with very little
risk of a call.

     We also bought more  asset-backed  securities,  including  bonds  backed by
commercial   mortgages  and  home-equity   loans.   These  bonds  added  greater
diversification to the fund's fixed-income holdings. We purchased them when they
were more  attractively  priced than most corporate  bonds,  and they have since
performed better than corporates.

LOOKING AHEAD, WHAT ARE YOUR PLANS FOR THE FUND'S ASSET ALLOCATION STRUCTURE?

     We intend to position the portfolio more  defensively in the coming months.
With U.S.  stock market  indices at or near all-time  highs and U.S. bond yields
close to record lows, we think it makes sense to be a little cautious.

     For the Strategic Moderate fund, this means cutting back on U.S. stocks and
shifting  into U.S.  bonds and cash.  Domestically,  we believe  that bonds have
better return potential than stocks for the second half of 1998.

WHAT MAKES U.S. BONDS MORE ATTRACTIVE THAN STOCKS?

     It comes down to whether you think the high stock prices or low bond yields
are sustainable  going forward.  For bonds,  the reasons behind the low interest
rate environment are a lack of inflation and the financial crisis in Asia. These
situations  aren't  likely to change in the next six  months--it  will be awhile
before Asia solves its economic problems,  and in the meantime,  expectations of
low  commodities  prices and cheap  exports  from Asia  should  help keep global
inflation low.

     The stock market rally,  on the other hand, has been dependent on a healthy
U.S. economy and solid corporate earnings growth.  Corporate profits are already
lower than they were a year ago, and we expect them to remain lackluster through
the end of this year. In addition,  a big build-up of  inventories  in the first
quarter and weak consumer demand from Asia will probably slow the economy.

     The bottom line is that we see more  downside risk in stocks than in bonds.
And even if both  markets  go  sideways  for the rest of the year,  bonds  offer
interest  rates  of 5-6% a year,  whereas  stocks  pay  out  dividends  of 2% or
less--if they pay any at all.

ARE YOU PLANNING TO SHIFT SIGNIFICANTLY OUT OF U.S. STOCKS?

     No.  The  adjustments  I'm  talking  about are  likely to be fairly  small.
Strategic Moderate is managed to maintain a specific strategic  position,  so we
don't stray too far from its neutral asset mix. To make sure of this, the fund's
prospectus  includes operating ranges for each asset class that we are obligated
to stay within.  For example,  our neutral  weighting  for stocks is 60%, and we
must keep it between 50% and 70%.

ARE THERE STILL GOOD INVESTMENT OPPORTUNITIES OVERSEAS?

     Definitely. Europe is still a great place to invest, especially for stocks,
as privatization and productivity improvements sweep the Continent. Unemployment
remains an issue,  and it might get worse before it gets better as companies cut
costs and become more  efficient.  But if Europe  continues  along the same path
that the U.S.  started on five years ago, the region will likely have  healthier
economies and lower unemployment down the road.

     Asia, on the other hand, is not yet a buying opportunity. Japan still needs
to address its banking  crisis,  economic  woes, and growing  government  budget
deficit.  Until Japan  starts to make some  progress,  the rest of Asia won't be
able to fully recover from its own problems.

     As a result,  we plan to maintain at least a neutral  weighting  in foreign
stocks and continue our concentration in Europe.

Forward foreign currency exchange contracts are used by the portfolio management
team in an effort to protect  foreign  investments  against  declines in foreign
currencies.  This is also known as hedging.  The contracts are called  "forward"
because they allow your fund to exchange a foreign  currency for U.S. dollars at
a date in the  future--and  at a price (known as the exchange  rate) agreed upon
when the contract is initially entered into.

Strategic Aggressive--Q&A
- -----------------------------------------------------------------------------

     An interview  with Jeff Tyler and Brian Howell,  portfolio  managers on the
American Century Strategic Asset Allocation funds management team.

HOW DID THE STRATEGIC AGGRESSIVE FUND PERFORM?

     For the six months ended May 31,  1998,  the fund's  Investor  Class shares
posted  a total  return  of  12.74%,  compared  with  the  9.60%  return  of its
benchmark.  (See the Total  Returns  table on the  previous  page for other fund
performance comparisons.)

WHAT IS THE FUND'S BENCHMARK?

     It's a combination of 11 different market indices--four U.S. stock indices,
two foreign stock indices,  two U.S. bond indices, two foreign bond indices, and
one money market  index.  These  indices  represent the various asset classes in
which the fund invests and are weighted to match the fund's neutral asset mix.

     Strategic  Aggressive beat its benchmark during the period,  mainly because
of the significant outperformance of its foreign stock holdings.

WHY DID YOUR FOREIGN STOCKS DO SO WELL?

     Asia was the main difference. We virtually eliminated Asian stocks from our
foreign  stock  portfolio,  and we are almost  double our neutral  weighting  in
Europe (see the chart on page 39). In contrast, Asia is more than a third of the
foreign stock portion of the benchmark.

     Asian stock  market  performance  was a  disaster,  while  European  equity
returns were among the best in the world,  with many countries  returning better
than  30%  during  the  six-month  period.  Foreign  stocks  make  up 20% of the
portfolio, so our shift into Europe added substantially to returns.

DID YOU MAKE ANY CHANGES TO THE ASSET MIX OVER THE PAST SIX MONTHS?

     We kept the  portfolio  pretty close to its neutral mix of 75% stocks,  20%
bonds, 5% cash. But stocks  outperformed bonds and cash during the period, so we
did some  minor  rebalancing.  We sold  some  stocks in April  and  shifted  the
proceeds into bonds and money market securities to maintain neutral weightings.

     Instead of making significant  changes to the asset mix, we concentrated on
making  adjustments within each asset class to try to enhance  performance.  Our
shift into European stocks is one example of this approach.

THE FUND'S BIGGEST HOLDING IS U.S. STOCKS. WHAT ADJUSTMENTS DID YOU MAKE TO THIS
PORTION OF THE PORTFOLIO?

     We began moving away from smaller, value-oriented stocks toward an emphasis
on large-company growth stocks. This was a difficult decision, because there are
a lot of very  attractive  values  among  the  stocks of  small-  and  mid-sized
companies.  However,  when  corporate  earnings  start to  weaken--as  they have
recently--investors   tend  to  gravitate  toward   large-company   stocks  with
relatively consistent growth and earnings.

     We also looked for companies that rely on domestic  consumer demand. A good
example is Home Depot,  which is a chain of retail  stores  that sells  building
materials and home improvement products. Home Depot's customers are in the U.S.,
where  economic  conditions are favorable and consumer  demand is healthy.  As a
result,  the  drop-off  in  demand  from Asia  hasn't  negatively  affected  the
company's sales.

Strategic Aggressive--Q&A
- -----------------------------------------------------------------------------
                                                                    (Continued)

     If anything,  Asia has had a positive effect on Home Depot's business--some
of the  products  the  company  sells are  produced  in Asia,  so its stores are
getting these products at cheaper prices.  It's not surprising that Home Depot's
stock returned more than 40% during the six-month period.

WHAT ABOUT THE FUND'S U.S. BOND HOLDINGS?

     We cut back our Treasury  holdings quite a bit as their yields hit all-time
lows.  In their place,  we added some  callable  government  agency  securities.
Callable securities tend to offer higher yields because they can be redeemed--or
called--by the issuer before the maturity date.

     Calling a bond is kind of like refinancing a home  mortgage--when  interest
rates fall significantly, homeowners can often reduce their interest payments by
taking out a new mortgage  and paying off the old one.  Bond issuers do the same
thing with callable  bonds when rates  decline.  But interest  rates were fairly
stable during the past six months,  so there wasn't any incentive for issuers to
call these  bonds.  As a result,  the fund got some extra yield with very little
risk of a call.

     We also bought more  asset-backed  securities,  including  bonds  backed by
commercial   mortgages  and  home-equity   loans.   These  bonds  added  greater
diversification to the fund's fixed-income holdings. We purchased them when they
were more  attractively  priced than most corporate  bonds,  and they have since
performed better than corporates.

LOOKING AHEAD, WHAT ARE YOUR PLANS FOR THE FUND'S ASSET ALLOCATION STRUCTURE?

     We intend to position the portfolio more  defensively in the coming months.
With U.S.  stock market  indices at or near all-time  highs and U.S. bond yields
close to record lows, we think it makes sense to be a little cautious.

     For the Strategic  Aggressive  fund, this means cutting back on U.S. stocks
and shifting into U.S. bonds and cash. Domestically,  we believe that bonds have
better return potential than stocks for the second half of 1998.

WHAT MAKES U.S. BONDS MORE ATTRACTIVE THAN STOCKS?

     It comes down to whether you think the high stock prices or low bond yields
are sustainable  going forward.  For bonds,  the reasons behind the low interest
rate environment are a lack of inflation and the financial crisis in Asia. These
situations  aren't  likely to change in the next six  months--it  will be awhile
before Asia solves its economic problems,  and in the meantime,  expectations of
low  commodities  prices and cheap  exports  from Asia  should  help keep global
inflation low.

Strategic Aggressive--Q&A
- -----------------------------------------------------------------------------
                                                                    (Continued)

     The stock market rally,  on the other hand, has been dependent on a healthy
U.S. economy and solid corporate earnings growth.  Corporate profits are already
lower than they were a year ago, and we expect them to remain lackluster through
the end of this year. In addition,  a big build-up of  inventories  in the first
quarter and weak consumer demand from Asia will probably slow the economy.

     The bottom line is that we see more  downside risk in stocks than in bonds.
And even if both  markets  go  sideways  for the rest of the year,  bonds  offer
interest  rates  of 5-6% a year,  whereas  stocks  pay  out  dividends  of 2% or
less--if they pay any at all.

ARE YOU PLANNING TO SHIFT SIGNIFICANTLY OUT OF U.S. STOCKS?

     No.  The  adjustments  I'm  talking  about are  likely to be fairly  small.
Strategic Aggressive is managed to maintain a specific strategic position, so we
don't stray too far from its neutral asset mix. To make sure of this, the fund's
prospectus  includes operating ranges for each asset class that we are obligated
to stay within.  For example,  our neutral  weighting  for stocks is 75%, and we
must keep it between 60% and 90%.

ARE THERE STILL GOOD INVESTMENT OPPORTUNITIES OVERSEAS?

     Definitely. Europe is still a great place to invest, especially for stocks,
as privatization and productivity improvements sweep the Continent. Unemployment
remains an issue,  and it might get worse before it gets better as companies cut
costs and become more  efficient.  But if Europe  continues  along the same path
that the U.S.  started on five years ago, the region will likely have  healthier
economies and lower unemployment down the road.

     Asia, on the other hand, is not yet a buying opportunity. Japan still needs
to address its banking  crisis,  economic  woes, and growing  government  budget
deficit.  Until Japan  starts to make some  progress,  the rest of Asia won't be
able to fully recover from its own problems.

     As a result,  we plan to maintain at least a neutral  weighting  in foreign
stocks and continue our concentration in Europe.

Forward foreign currency exchange contracts are used by the portfolio management
team in an effort to protect  foreign  investments  against  declines in foreign
currencies.  This is also known as hedging.  The contracts are called  "forward"
because they allow your fund to exchange a foreign  currency for U.S. dollars at
a date in the  future--and  at a price (known as the exchange  rate) agreed upon
when the contract is initially entered into.

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 fund shares outstanding gives you the price of an
individual share, or the net asset value per share.

NET ASSETS are also broken out by capital (money invested by shareholders);  net
income not yet paid to shareholders; net gains earned on investment activity but
not yet paid to  shareholders  or net losses on  investment  activity  (known as
realized gains or losses);  and gains or losses on securities still owned by the
fund (known as unrealized appreciation or depreciation). This breakout 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.

MAY 31, 1998 (UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION--American  Century  Strategic  Asset  Allocations,  Inc.  (the
Corporation)  is  registered  under  the  Investment  Company  Act of 1940 as an
open-end diversified  management investment company.  American Century Strategic
Allocation: Conservative (Strategic Allocation:  Conservative), American Century
Strategic  Allocation:  Moderate (Strategic  Allocation:  Moderate) and American
Century Strategic Allocation: Aggressive (Strategic Allocation: Aggressive) (the
Funds) are three of the funds currently  issued by the  Corporation.  The Funds'
investment  objective  is to  provide as high a level of total  return  (capital
appreciation  plus  dividend and  interest  income) as is  consistent  with each
Fund's risk profile. The Funds seek to achieve this by diversifying  investments
among  three  asset  classes  - equity  securities,  bonds  and cash  equivalent
instruments,  the mix of which will depend on the risk profile of each Fund. 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
each 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,  related to all classes
of the Funds, are in accordance with accounting  policies  generally accepted in
the investment company industry.

     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.  Debt securities not
traded on a  principal  securities  exchange  are  valued  through a  commercial
pricing  service or at the mean of the most  recent bid and asked  prices.  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--The  accounting  records  of the Funds are
maintained in U.S. dollars.  All assets and liabilities  initially  expressed in
foreign currencies are converted into U.S. dollars at prevailing exchange rates.
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.

     Net realized foreign currency  exchange gains or losses arise from sales of
foreign  currencies  and the  difference  between  asset and  liability  amounts
initially stated in foreign  currencies and the U.S. dollar value of the amounts
actually  received or paid. Net unrealized  foreign  currency  exchange gains or
losses  arise from  changes in the value of assets and  liabilities,  other than
portfolio securities, resulting from changes in the exchange rates.

     Net realized  and  unrealized  foreign  currency  exchange  gains or losses
occurring  during the holding period of portfolio  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 for the purpose of settling specific
purchases or sales of securities  denominated in a foreign  currency or to hedge
the Funds'  exposure  to  foreign  currency  exchange  rate  fluctuations.  When
required, the Funds will segregate assets in an amount sufficient to cover their
obligations  under the hedge  contracts.  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.  Forward contracts involve elements of market risk in
excess of the amount reflected in the Statements of Assets and Liabilities.  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,

                                                                    (Continued)

represented by securities,  received in a repurchase  transaction be transferred
to the  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
equal to or  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 policy of the Funds to  distribute  all net
investment  income  and  net  realized  capital  gains  to  shareholders  and to
otherwise  qualify as a regulated  investment  company  under  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,  with the  exception  of those  for  Strategic  Allocation:
Aggressive which are declared and paid annually. Distributions from net realized
capital gains are declared and paid annually.

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

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

     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  Management  Agreements  with ACIM that
provide each Fund with investment  advisory and management  services in exchange
for a single,  unified management fee per class. The Agreements provide that all
expenses of the Funds, except brokerage commissions,  taxes, interest,  expenses
of those 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 computed daily and paid monthly based
on each class's average daily closing net assets during the previous month.  The
annual management fee for each class of the Funds is as follows:

    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

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

SHARE CLASSES

     Until  September 3, 1996, the Strategic Asset  Allocation  funds issued one
class of fund  shares,  reflecting  the fact that most  investors  bought  their
shares  directly  from  American  Century.  All  investors  paid the same annual
unified management fee and did not pay any commissions or other fees to purchase
shares from American Century.

     Now  more  share  purchases  are  made  by  investors   through   financial
intermediaries  (who ordinarily are compensated for the additional services they
provide).  In September  1996,  American  Century  began to offer two classes of
shares for the Strategic Asset Allocation  funds. One class is for investors who
buy directly  from  American  Century,  the other for  investors who buy through
financial intermediaries.

     The  original  class of  Strategic  Asset  Allocation  shares is called the
INVESTOR CLASS. All shares issued and outstanding before September 3, 1996, have
been  designated  as Investor  Class shares.  Investor  Class shares may also be
purchased  after September 3, 1996.  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. THE PRICE AND PERFORMANCE
OF THE  INVESTOR  CLASS  SHARES  ARE  LISTED IN  NEWSPAPERS.  NO OTHER  CLASS IS
CURRENTLY LISTED.

     In  addition,  there is an  ADVISOR  CLASS,  which is 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.

IMPORTANT NOTICE FOR ALL IRA AND 403(B) SHAREHOLDERS

     As required by law, any  distributions  you receive from an IRA and certain
403(b)  distributions [not eligible for rollover to an IRA or to another 403(b)]
are subject to federal  income tax  withholding  at the rate of 10% of the total
amount withdrawn,  unless you elect not to have withholding  apply. If you don't
want us to withhold on this amount, you may send us a written notice not to have
the federal  income tax  withheld.  Your written  notice is valid for six months
from the date of receipt at American Century.  Even if you plan to roll over the
amount you withdraw to another tax-deferred  account, the withholding rate still
applies to the withdrawn  amount unless we have received a written notice not to
withhold federal income tax within six months prior to the withdrawal.

     When you plan to withdraw,  you may make your  election by  completing  our
Conversions/  Redemptions  form or an IRS Form W-4P.  Call American  Century for
either form. Your written election is valid for only six months from the date of
receipt at American Century. You may revoke your election at any time by sending
a written notice to us.

     Remember, even if you elect not to have income tax withheld, you are liable
for paying income tax on the taxable  portion of your  withdrawal.  If you elect
not to have income tax  withheld or you don't have enough  income tax  withheld,
you may be  responsible  for payment of estimated  tax. You may incur  penalties
under the estimated tax rules if your withholding and estimated tax payments are
not sufficient.

Background Information
- -----------------------------------------------------------------------------
INVESTMENT PHILOSOPHY AND POLICIES

     Each  American  Century  Strategic  Asset  Allocation  fund  invests  in  a
diversified  portfolio of stocks,  bonds and money market  securities,  with the
objective of achieving as high a level of total return as is consistent with the
fund's  asset  mix.  The funds  rely on a team  management  approach--groups  of
managers are  responsible  for the ongoing  active  management of the individual
fund components.

     STRATEGIC  ALLOCATION:  CONSERVATIVE  emphasizes  bonds  and  money  market
securities to provide  regular  income and principal  protection.  The fund also
provides the potential for moderate  long-term  growth by investing a portion of
its assets in stocks.

     STRATEGIC ALLOCATION: MODERATE emphasizes common stocks for their long-term
growth  prospects,  but it  maintains a sizable  stake in bonds and money market
securities to provide some income and increase overall price stability.

     STRATEGIC  ALLOCATION:  AGGRESSIVE  focuses primarily on common stocks as a
source of long-term  growth,  but it maintains a small  portion of its assets in
bonds and money market  securities to provide a modest amount of income and help
cushion the share price volatility of the stock portion.

COMPARATIVE INDICES

     The  indices  listed  below  are  used  in the  report  to  serve  as  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 to be a broad measure of U.S. stock market
performance.

     The RUSSELL 2000 is created by taking the 3,000  largest  stocks  (based on
market value) and removing the biggest  1,000.  It is considered a broad measure
of small-company stock performance.

     The SALOMON  BROTHERS  BROAD  INVESTMENT  GRADE INDEX consists of Treasury,
government agency,  mortgage-backed and corporate  securities with maturities of
one year or more.

     The LEHMAN AGGREGATE BOND INDEX reflects the price fluctuations of Treasury
securities,  agency  securities,   corporate  bond  issues  and  mortgage-backed
securities.

     The MORGAN STANLEY EUROPE,  AUSTRALIA,  FAR EAST (EAFE(reg.tm))  INDEX is a
widely followed group of stocks from 22 different countries.

     The SALOMON  BROTHERS  NON-U.S.  WORLD  GOVERNMENT  BOND INDEX  consists of
fixed-income government bonds from 16 countries.

     The  THREE-MONTH  TREASURY  BILL INDEX is  derived  from  secondary  market
interest rates as published by the Federal Reserve Bank.

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 60-65.

STOCK PORTFOLIO STATISTICS

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

* DIVIDEND YIELD--a  percentage return calculated by dividing a company's annual
cash dividend by the current market value of the company's stock.

*  PRICE/EARNINGS  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 a percentage.  (Earnings per share is calculated by dividing
a company's after-tax earnings by its outstanding shares.)

BOND PORTFOLIO STATISTICS

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

*  WEIGHTED  AVERAGE  MATURITY  (WAM)--a  measurement  of the  sensitivity  of a
fixed-income  portfolio to interest rate changes. WAM indicates the average time
until the securities in the portfolio  mature,  weighted by dollar  amount.  The
longer the WAM, the more interest rate  exposure and  sensitivity  the portfolio
has.

*  AVERAGE  DURATION--another  measure  of  the  sensitivity  of a  fixed-income
portfolio to interest rate changes.  Duration is a time-weighted  average of the
interest  and  principal  payments  of the  securities  in a  portfolio.  As the
duration  of a portfolio  increases,  so does the impact of a change in interest
rates on the value of the portfolio.

FIXED-INCOME SECURITY TYPES

* ASSET-BACKED SECURITIES--debt securities that represent ownership in a pool of
receivables, such as credit card debt, auto loans or mortgages.

* CORPORATE  SECURITIES--debt  securities or instruments issued by corporations.
Short-term  corporate  securities  are typically  issued to raise cash and cover
current  expenses  in  anticipation  of  future  revenues;  long-term  corporate
securities  are  issued  to  finance  capital  expenditures,  such as new  plant
construction or equipment purchases.

* FOREIGN GOVERNMENT SECURITIES--debt securities issued or guaranteed by foreign
governments or their political subdivisions. Some of these securities are direct
obligations  of the  issuing  government;  others  are  backed  by some  form of
government sponsorship.

* MORTGAGE-BACKED  SECURITIES--debt securities that represent ownership in pools
of  mortgage   loans.   Most   mortgage-backed   securities  are  structured  as
"pass-throughs"--the monthly payments of principal and interest on the mortgages
in the pool are  collected by the bank that is servicing  the  mortgages and are
"passed through" to investors.  While the payments of principal and interest are
considered  secure (many are backed by government agency  guarantees),  the cash
flow is less certain than in other fixed-income investments.  Mortgages that are
paid off early reduce future interest payments from the pool.

* U.S. GOVERNMENT AGENCY  SECURITIES--debt  securities issued by U.S. government
agencies  (such as the Federal Home Loan Bank and the Federal Farm Credit Bank).
Some  agency  securities  are  backed by the full  faith and  credit of the U.S.
government,  while others are guaranteed only by the issuing agency.  Government
agency  securities  include  discount  notes  (maturing in one year or less) and
medium-term notes, debentures and bonds (maturing in three months to 50 years).

* U.S.  TREASURY  SECURITIES--debt  securities  issued by the U.S.  Treasury and
backed by the direct  "full  faith and  credit"  pledge of the U.S.  government.
Treasury  securities  include  bills  (maturing  in one  year  or  less),  notes
(maturing in two to ten years) and bonds (maturing in more than ten years).
