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 turn,  will make us successful.  That is the principle that

     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 & As with fund managers.
We  hope  the  new  design  will  make  the   reports   more   interesting   and
understandable,  and easier for you to 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 report  actually costs slightly less than the old ones. They 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.

   Stocks have posted  historic  returns over the last few years.  The first six
months of the year  continued  the  momentum,  despite a slowdown  in the second
quarter.  Large companies once again outpaced  smaller ones. The generous market
values accorded many very large, high-profile companies grew even more generous,
while midsize and small stocks turned in respectable results. Growth stocks once
again outpaced value stocks.

     We've been optimistic  about the financial  markets for many years,  and we
continue  to believe  stocks  should  produce  fine  results  over the long run.
Corporate  America  is in good  haelth.  Many  companies  have  cleaned up their
balance sheets,  are highly productive and are generating  impressive returns on
products and investments. While the economic crisis in the Far East has affected
earnings in a number of areas, the U.S. economy is sound.

     Despite  the  general  run-up in  stocks,  not every  company is selling at
record  prices.  We're  still in a market of  individual  businesses.  There are
plenty of attractive  values--companies  whose earnings growth, asset worth, and
credit quality have not been fully recognized.

     The ability of our value equity team to find these  opportunities  is based
on its use of fundamental  analysis and  traditional  value measures to identify
inexpensive stocks and assets. Our aim, always, is to help investors reach their
financial goals.

     Finally,  we hope you like the new  design of this  report.  Our annual and
semiannual  reports  contain  a wealth of  information  on fund  strategies  and
holdings.  The new design is intended to make this  information  more accessible
and should encourage you to take a closer look.

     We appreciate your investment with American Century.

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

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

MARKET PERSPECTIVE

o   The U.S. stock market  continued its powerful  advance during the first half
    of 1998. The S&P 500 gained 17.66%.

o   A robust  economy has fueled the stock market's  performance.  Low inflation
    and interest rates have contributed to a strong economy.

o   Earnings growth and profitability are top corporate priorities. A tight U.S.
    labor  market and the  ongoing  economic  crisis in Asia  caused  only minor
    pullbacks in late 1997 and the first six months of 1998.

o   Stock prices and  investor  expectations  remain very high.  On a historical
    basis, corporate assets are richly valued, and the average stock dividend is
    at a record low.

MANAGEMENT Q&A

o   VP Value posted a 5.90%  return for the six months  ended June 30, 1998.  It
    trailed its benchmark,  the S&P 500/BARRA Value Index,  which gained 12.13%.
    The S&P 500 registered a 17.66% return.

o   VP Value's  investment  style and the size of  companies in which it invests
    dictated  its  performance.  During  the first half of 1998,  growth  stocks
    provided the best returns while value stocks lagged. Investors also showed a
    preference for large, well-known companies.

o   VP Value was overweighted  relative to the index in industries that suffered
    the  effects of  deflationary  pricing  pressures,  such as energy and basic
    materials.

o   General merchandise and grocery retailers were top performers during the six
    months.   Giant  Food,  VP  Value's   largest  holding  during  the  period,
    contributed  significantly  to returns.  Two large  clothing  retailers also
    added to performance.

o   We increased  holdings in energy  producers  as their prices and  valuations
    became  attractive  in early 1998.  We  decreased  the fund's  weighting  in
    general  merchandise  and  food  retailers  as  consolidation  within  these
    industries drove their prices to what we believe are fair valuations.

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

/photo Mark Mallon/
Mark Mallon, senior vice president and managing director of American Century
Investments

A POWERFUL UPSLOPE

     Just how quickly has the stock market  appreciated over the past few years?
It took  approximately 16 years,  from 1970-1985,  for the Standard & Poor's 500
Index to double.  Only six years later,  it had doubled again,  and roughly five
years after that,  in early 1997, it had doubled once more, to 800. As the chart
on this page illustrates, the S&P 500's recent climb has been very steep. At the
end of June 1998, the index was just over 1100.

     Looked at another way, calendar 1995-1997 marked one of the best three-year
performance  runs on record.  It was, in fact, the most  consistent  performance
ever for  large-stock  indices  such as the S&P 500. All three years saw returns
top 20%. During the six months ended June 30, the S&P 500 barely paused to catch
its breath, gaining 17.66%.

      Lower  corporate  earnings,  a tight U.S.  labor  market,  and the ongoing
economic  crisis in Asia caused only minor pullbacks in late 1997 and the second
quarter of 1998.

A POWERHOUSE ECONOMY

     Stocks  owe  much  of  their  success  to a  robust  economy  with  minimal
inflation.  The U.S. economy is currently  demonstrating a vigor we haven't seen
in a generation.

o U.S. economic growth hit 3.8% in 1997, and 5.5% in the first quarter of 1998.

o Inflation was a mere 1.4% for the 12 months ended June 30.

o In 1997, prices rose at the slowest pace in 12 years.

o Real interest rates are among the lowest since the 1960s.

o Unemployment in 1997 was the lowest in 28 years.

o The U.S. government is projecting the first budget surplus in 30 years.

     A successful market is also tied to the success of individual companies.

     Earnings growth and productivity are at the top of the business agenda.  We
are among  the most  technologically  proficient  industrial  nations,  and as a
result, U.S. companies are enjoying  extraordinarily high profitability.  A wave
of mergers,  involving such high-profile  names as Travelers Group and Citicorp,
has, in general, increased efficiency and boosted profits.

     In 1997 and the first quarter of 1998,  earnings  growth  slowed,  but only
after a  double-digit  growth  spurt that lasted five years.  Given the positive
business climate,  it's not surprising stocks remain such a popular  investment,
and that cash continues to flow into the market at record volumes.

     However,  by some  traditional  measures,  stock prices are expensive.  The
average stock in the S&P 500 now costs more than 25 times last year's  earnings,
a historical high. Corporate

Market Perspective (continued)
- --------------------------------------------------------------------------------

assets are also richly  valued.  Investors are paying roughly five times balance
sheet assets, or twice the historical average. The dividend yield on the average
S&P 500 stock has fallen to less than 1.5%, another record.

BIG WAS BETTER, GROWTH WAS IN

     As the accompanying chart makes clear, large companies (as reflected in the
S&P 500) continued to outperform  midsize and small  companies in the first half
of 1998. Leadership has been narrow. The largest 100 stocks in the S&P, measured
by market value,  have far  outdistanced the remaining 400. And the very largest
growth stocks--GE,  Coca-Cola, Microsoft, and other household names--have posted
the biggest gains. The "mega stocks" are in vogue because they are liquid,  that
is, easier to trade in large quantities.  In theory, their liquidity should make
them easier to exit if the stock market slips.

     The fascination  with growth and size has been prevalent for several years.
It was also in vogue a generation ago, in the early  seventies,  when the "Nifty
Fifty"  (companies  that were also  household  names)  provided the  performance
fireworks.

EARNINGS, INFLATION, AND  INTEREST RATES

     What could  derail  the  financial  markets?  An upturn in  inflation  or a
substantial  decline in earnings  probably would. You don't have to look farther
than the second  quarter,  when the Asian  crisis  threatened  earnings  and the
Federal Reserve hinted a rate hike was possible.  In late 1997, the spike in oil
prices,  combined  with the deepening  Asian crisis,  also raised the specter of
higher inflation and lower earnings--and stocks fell back.

     If  inflation  picks  up,  interest  rates are  likely to rise too,  as the
Federal  Reserve  Board tries to head off  inflation  by pushing  rates  higher.
Higher  interest  rates  increase  the  cost of  borrowing  for  everyone,  from
corporations to prospective  home buyers,  and thus tend to slow economic growth
and dampen inflation.

     In 1997, inflation failed to take off. Oil prices went into a tailspin when
Asian  demand  fell.  In early 1998,  as crude oil prices hit a  nine-year  low,
interest  rates  declined  and stocks  soared even though the fallout  from Asia
still threatened to slow both corporate earnings and U.S. economic growth.

     This is a resilient  market.  We believe its long-term  prospects are still
favorable. But investor expectations are running high, which is reflected in the
S&P 500's steep climb over the last three and a half years. In this environment,
stocks could prove vulnerable to disappointments.

VP Value--Q&A
- --------------------------------------------------------------------------------

     An interview with Phil Davidson and Todd Vingers, portfolio managers on the
VP Value investment team.

HOW DID THE FUND PERFORM FOR THE SIX MONTHS ENDED JUNE 30, 1998?

     VP Value lagged its benchmark during the first half of 1998, returning just
5.90%. The fund's benchmark, the S&P 500/BARRA Value Index, gained 12.13%, while
the S&P 500 registered a 17.66% return.

WHAT EXPLAINS THE FUND'S PERFORMANCE COMPARED TO THE BROADER MARKET?

     VP Value's lackluster  performance was dictated primarily by its investment
style and the size of the companies it tends to own. During the first six months
of the year,  growth stocks provided the best returns while value stocks lagged.
Investors also continued to favor the larger,  better known companies that drive
the S&P 500 Index. These larger companies became attractive to investors in late
1996 amid fears that the Federal  Reserve  would  increase  short-term  interest
rates. The preference for larger companies  continued through the Asian currency
crisis  that  unfolded a year later.  Investors  held onto the stocks of bigger,
better known  companies--even  those with  exposure to Asian  economies--because
larger  companies  are  generally  easier to trade.  Liquidity is an  attractive
feature in an  uncertain  or  volatile  market.  At the same time,  the  midsize
companies VP Value focuses on became more difficult to trade.

     Although style and capitalization factors have dampened recent performance,
we  believe  the   market's   ongoing   preference   for  bigger   companies  is
unsustainable.  Many large-cap stocks currently are selling at record highs and,
in our opinion, have little potential for additional gains. In the meantime, the
popularity of large-cap  stocks and the depressed  prices of many mid-cap stocks
have created a wealth of opportunity  for value  investors.  We are finding many
mature, out-of-favor mid-cap companies whose stocks are attractively priced from
a risk-reward and value standpoint.

WHAT CAUSED VP VALUE TO UNDERPERFORM ITS BENCHMARK?

     VP Value was  underweighted  relative to the S&P  500/BARRA  Value Index in
several   better-performing   industries,   including   financial  services  and
communications  stocks.  Perhaps  more  significant,  however,  was  the  fund's
overweighting  in industries that suffered the effects of  deflationary  pricing
pressures. The energy and basic materials industries serve as good examples.

     We  increased  the fund's  holdings in energy  producers  in late 1997,  as
global  demand/supply  imbalances  depressed energy prices and valuations became
attractive.  As 1998 unfolded, oil prices remained under pressure while domestic
natural gas prices were stable to  improving.  Oil stocks may benefit  from OPEC
production  cuts,  while  domestic  natural  gas  producers  should   experience
seasonally stronger pricing. We expect that as cooler weather approaches, demand
for oil and gas will  increase,  and the portfolio is positioned to benefit from
this changing environment.  We are particularly  attracted to domestic producers
of natural gas because this key fuel continues to enjoy moderate demand growth.

     Prices of basic materials  companies fell in response to  overcapacity  and
the economic turmoil in Asia, which made them attractive on a valuation basis.
When prices are depressed, supply gen-

VP Value--Q&A (continued)

erally contracts.  Over time,  prices should recover as inventories  dwindle and
demand remains steady.

WHICH STOCKS OR SECTORS ADDED MOST TO RETURNS?

     Several of VP Value's top performers  were general  merchandise and grocery
retailers.  The stock that  contributed  the most to  performance  was,  for the
second  consecutive  period,  Giant Food,  Inc. This was also VP Value's largest
holding at 4.5% of  investments  at December 31,  1997.  Giant Food is a leading
chain of retail  food  stores and  pharmacies.  The  company  recovered  from an
employees   strike  in  1997  and   subsequently   implemented   an   aggressive
merchandising  program,  which  resulted  in solid  sales  gains  in a  somewhat
sluggish market. Giant's stock price rose sharply in May 1998 upon the news that
it would be acquired by Ahold,  a  Netherlands-based  global food  retailer with
significant  properties in the United States.  We subsequently sold our position
at a substantial gain.

     Other  retailers  that  added  to  performance  were  Dillard's,   Inc.,  a
department  store chain with more than 270 outlets  nationwide,  and  Mercantile
Stores,  which  operates  about 100 stores  primarily  in the South and Midwest.
Dillard's  operating  margins had been under pressure due to  inordinately  high
inventories,  which forced the company to market aggressively in late 1997. That
resulted in a sharp reduction in earnings. Meanwhile,  Mercantile struggled with
lower-than-expected  revenue  growth and rising costs.  The tide turned for both
companies  in  May,  when  it  was  announced  that   Dillard's   would  acquire
Mercantile--a  marriage we think is a good fit, given that  Mercantile's  stores
are located  primarily in markets  where  Dillard's  has not had a presence.  We
purchased  Mercantile at various times over the last two years at prices between
$45 and $65 per share, and sold it at $79 after the acquisition was announced.
We continue to hold a position in Dillard's.

     Outside the retail sector,  top-performing stocks included Beckman-Coulter,
Inc. and Cooper  Industries.  Beckman-Coulter  makes laboratory  instruments and
related products, such as centrifuges,  reagent supplies and systems that detect
and  quantify  various  substances  in blood and other  fluids.  The company has
benefited  from the  expectation  that its 1997  acquisition  of Coulter  Corp.,
another  manufacturer  of  laboratory  instruments  and  supplies,  will  add to
earnings and cash flow over the long term.  We initially  purchased the stock in
September 1997 at attractive prices.

     Cooper Industries manufactures electrical products, tools and hardware, and
automotive products.  The company's stock appreciated after management announced
in April 1998 its intention to sell its automotive  arm. We sold our holdings as
the stock reacted positively to this  announcement,  reaching a level we believe
represented  fair value.  We rebuilt a position  in Cooper in June,  following a
slight  earnings  shortfall that brought the stock's price back within our value
parameters.

WHICH STOCKS WERE DISAPPOINTING?

     VP Value's worst performing  stock during the six months was  BetzDearborn.
This company is one of the world's leading suppliers of chemicals, equipment and
services for treating  industrial and commercial water systems.  The company has
suffered recently on two fronts. Although just 6% of BetzDearborn's revenues are
derived from the Far East,  that region of the world  represented  the company's
most rapidly  growing market.  The collapse of the Asian  economies  effectively
stalled the company's growth engine.

VP Value--Q&A (continued)
- --------------------------------------------------------------------------------

BetzDearborn's  troubles were further  compounded by unexpected costs associated
with the merger of Dearborn with Betz in 1996.  However,  we are maintaining the
position  because we are confident  BetzDearborn  will overcome these short-term
difficulties.

     Mercantile Bancorporation, Inc., which was the fund's best performing stock
in the second half of last year, saw its share price fall.  Although the banking
and financial services sector in general is booming, stock price appreciation in
the last six months has been  concentrated  primarily among the big money center
banks,  while regional  groups  underperformed.  We favor regional banks because
they  generally are more  attractively  valued and have lower risk profiles than
bigger  banks.  We began  buying  Mercantile  when its price was  around $30 per
share.  The stock  closed out 1997 at $60 per  share--a  record  high--and  then
dropped to about $50 per  share.  Mercantile  is very  solid,  its  fundamentals
remain good, and we're very pleased with the  contributions  this stock has made
to the portfolio over time. We believe we will see additional price appreciation
going forward.

     Although food and beverage stocks contributed significantly to performance,
one stock in this sector was  disappointing.  IBP, the world's  largest beef and
pork processor,  suffered  lower-than-expected  earnings when the Asian economic
crisis hurt the company's export business.  More recently, food safety concerns,
plant  start-up  costs and an  abundant  supply of meat  combined to drive stock
prices down. However, IBP's plans to strengthen its core meat operations and its
efforts to grow its animal by-products  division bode well for the future, so we
are maintaining our position.

WHAT CHANGES DID YOU MAKE TO THE  PORTFOLIO DURING THE SIX MONTHS?

     We  increased  energy  holdings  as their  valuations  became  increasingly
attractive.  We decreased the fund's  holdings in general  merchandise  and food
retailers, as consolidation within these sectors drove prices to what we believe
are fair valuations. We also increased holdings in specialty chemical companies,
based on their  attractive  valuations  and good long-term  business  prospects.
Specialty  chemical  companies  are more  stable than their  commodity  chemical
siblings, and have less exposure to economic downturns.

WHAT IS YOUR OUTLOOK GOING FORWARD?

     VP Value's  investment  objective is long-term  capital growth. In pursuing
that objective,  the fund attempts to participate in up markets and also protect
assets in down  markets.  We  believe  the  current  narrow  market  leadership,
dominated by large-cap stocks demonstrating  near-term growth, is unsustainable.
We  continue  to  search  for and  purchase  securities  of  sound,  established
businesses in the mid-cap range. We remain confident VP Value's performance will
improve with the return of a more normal market  environment--one in which stock
prices advance in line with company earnings and value.

UNDERSTANDING  THE STATEMENT OF ASSETS AND LIABILITIES  --This page 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.  The net assets  divided by the number of 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
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  breakout  tells  you the  value  of net  assets  that  are
performance-related,  such as income and  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, 1998 (UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION  --  American   Century   Variable   Portfolios,   Inc.,  (the
Corporation)  is  registered  under  the  Investment  Company  Act of 1940 as an
open-end diversified  management  investment company.  American Century VP Value
(the  Fund) is one of the six  series of funds  issued by the  Corporation.  The
Fund's investment  objective is long-term capital growth.  Income is a secondary
objective.  The Fund seeks to achieve its  investment  objective by investing in
securities  management  believes to be undervalued at the time of purchase.  The
following  significant  accounting  policies,   related  to  the  Fund,  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 Fund 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 investments  are a component of realized
gain  (loss)  on  investments  and  unrealized  appreciation  (depreciation)  on
investments, respectively.

     FORWARD  FOREIGN  CURRENCY  EXCHANGE  CONTRACTS  -- The Fund 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 Fund's  exposure  to  foreign  currency  exchange  rate  fluctuations.  When
required,  the Fund will segregate  assets in an amount  sufficient to cover its
obligations  under the hedge  contracts.  The net U.S.  dollar  value of foreign
currency  underlying  all  contractual  commitments  held  by the  Fund  and the
resulting  unrealized  appreciation or depreciation  are determined  daily using
prevailing exchange rates.  Forward contracts involve elements of risk in excess
of the amount  reflected in the  Statement of Assets and  Liabilities.  The Fund
bears 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.  There were no open
forward foreign currency exchange contracts at June 30, 1998.

     FUTURES  CONTRACTS -- The Fund may enter into stock index futures contracts
in order to manage the Fund's exposure to changes in market  conditions.  One of
the risks of entering into futures  contracts  includes 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 Fund is
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  Fund.  The
variation  margin is equal to the  daily  change  in the  contract  value and is
recorded as an unrealized  gain or loss. The Fund  recognizes 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.  There  were  no  open  futures
contracts at June 30, 1998.

     REPURCHASE AGREEMENTS -- The Fund may enter into repurchase agreements with
institutions that the Fund's investment manager,

Notes to Financial Statements (continued)
- --------------------------------------------------------------------------------

JUNE 30, 1998 (UNAUDITED)

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
equal  to or  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 or Agency obligations.

     INCOME TAX STATUS -- It is the policy of the Fund to distribute all taxable
income and 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  --   Distribu-tions  to  shareholders  are
recorded on the ex-dividend date.  Distributions  from net investment income and
net realized capital 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 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.  These estimates and assumptions  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 a Management  Agreement  with ACIM that
provides the Fund with investment  advisory and management  services in exchange
for a single, unified fee. The Agreement provides that all expenses of the Fund,
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 the Fund's  average
daily closing net assets during the previous  month.  The annual  management fee
for the Fund is 1.00%.

     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.

- --------------------------------------------------------------------------------
3. INVESTMENT TRANSACTIONS

     Purchases  and  sales  of  investment   securities,   excluding  short-term
investments, totaled $233,831,062 and $160,773,136, respectively.

     As  of  June  30,  1998,   accumulated  net  unrealized   depreciation  was
$5,940,738,  based on the aggregate  cost of  investments  of  $282,471,942  for
federal  income tax  purposes,  which  consisted of unrealized  appreciation  of
$10,375,509 and unrealized depreciation of $16,316,247.

Background Information
- --------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY AND POLICIES

     Conservative  investment  practices are the hallmark of American  Century's
conservative  equity  funds.  Broad  diversification  across many  industries is
stressed to reduce the impact of one sector on fund performance.  The management
team also looks for dividend  yield,  since dividend  income can help offset the
impact of market  downturns  on fund  performance.  American  Century  funds are
managed by teams,  rather than by one "star" manager. We believe this enables us
to make better, more consistent management decisions.

     VP VALUE'S investment objective is long-term capital growth, with income as
a secondary objective. To achieve this objective, the fund invests in the equity
securities of seasoned,  established  businesses that the fund's management team
believes are temporarily undervalued.  This is determined by comparing a stock's
share price with key financial measures,  including  earnings,  book value, cash
flow and  dividends.  If the stock's price relative to these measures is low and
the  company's  balance  sheet is  solid,  its  securities  are  candidates  for
purchase.  The  management  team may  secondarily  look for income  when  making
portfolio selections.

COMPARATIVE INDICES

     The indices  listed  below are used in the report to serve as a  comparison
for the performance of the fund. They are not investment  products available for
purchase.

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

     The S&P 500/BARRA VALUE index is a capitalization-weighted index consisting
of S&P 500 stocks that have lower price/book ratios and, in general, share other
characteristics associated with value stocks.

     The S&P MIDCAP 400 index is a  capitalization-weighted  index of the stocks
of the 400 largest leading U.S companies not included in the S&P 500. Created by
Standard & Poor's Corporation,  it is considered to represent the performance of
mid-cap stocks generally.

     The  RUSSELL  2000  INDEX was  created  by the Frank  Russell  Company.  It
measures  the   performance   of  the  2,000   smallest  of  the  3,000  largest
publicly-traded U.S. companies based on total market capitalization. The Russell
2000 represents  approximately 10% of the total market capitalization of the top
3,000 companies. The average market capitalization of the index is approximately
$420 million.

Glossary
- --------------------------------------------------------------------------------

RETURNS

o TOTAL  RETURN  figures  show the overall  percentage  change in the value of a
hypothetical  investment  in  the  fund  and  assume  that  all  of  the  fund's
distributions are reinvested.

o AVERAGE ANNUAL RETURNS  illustrate the annually  compounded returns that would
have produced the fund's cumulative total returns if the fund's  performance had
been  constant  over the  entire  period.  Average  annual  returns  smooth  out
variations in a fund's return;  they are not the same as  year-by-year  results.
For year-by-year  total returns,  please refer to the "Financial  Highlights" on
page 16.

PORTFOLIO STATISTICS

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

o 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.)

o 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.

TYPES OF STOCKS

o  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.

o 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.

o 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.

o 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.

o  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.

o 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 Index.

o 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.

STATISTICAL TERMINOLOGY

o  PRICE/BOOK  RATIO--  a stock  value  measurement  calculated  by  dividing  a
company's stock price by its book value per share,  with the result expressed as
a multiple  instead of as a  percentage.  (Book value per share is calculated by
subtracting a company's liabilities from its assets, then dividing that value by
the number of outstanding shares.)

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 report  actually costs slightly less than the old ones. They 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.

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

[photo James E. Stowers, Jr. and James E. Stowers III]
James E. Stowers III, seated, with James E. Stowers, Jr.

     When we launched our first  international  fund in 1991, our purpose was to
provide meaningful  diversification for investors in markets outside the U.S. We
also believed many  internationally-based  companies were attractive investments
in their own right. We were convinced as well that our proprietary discipline of
purchasing  individual  businesses with accelerating revenues and earnings would
prove  effective  abroad.  Over the  years,  this  strategy  has  produced  very
respectable gains for our shareholders.

     In the first six months of the year foreign  markets  continued to generate
widely  diverse  returns.  The Far East and many  emerging  markets were sharply
lower,  while Europe saw stock prices surge. Our international  investment group
found  exciting  companies  worldwide.  The historic  changes in Europe were the
source of many  compelling  ideas,  but we identified  earnings  acceleration in
locations  as varied as Greece and India.  Members  of the  international  team,
which now stands at eleven, visited 21 countries during the six months.

     The  team's   focus  on  revenue  and  earnings   acceleration   helped  VP
International outperform its benchmark index. We're especially encouraged by the
portfolio's  performance given the serious crises in many developing  economies.
Our  international  team's  approach  adheres to the  investment  philosophy and
techniques  that we developed  over the last 25-plus  years.  We've been able to
blend  new  technology  and  resources  in  strategies   that  employ   earnings
acceleration and fundamental  stockpicking.  Our international team's ability to
use these strategies to find opportunities in an uncertain global environment is
clearly  reflected in the solid performance of the fund during the first half of
the year. Our aim, as always, is to help investors reach their financial goals.

     Finally,  we hope you like the new  design of this  report.  Our annual and
semiannual  reports  contain a wealth of information  about fund  strategies and
holdings.  The new design is intended to make this  information  more accessible
and should encourage you to take a closer look.

     We appreciate your investment with American Century.

Sincerely,

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

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

MARKET PERSPECTIVE

*   Performance in foreign  markets varied  widely.  The Morgan Stanley  Capital
    International  EAFE Index  gained  15.93% for the six months  ended June 30,
    1998.  EAFE  benefited from healthy gains in mature  European  markets while
    deepening economic problems hampered Asian markets.

*   A revitalized  Europe has some of the  strongest  growth rates in the world,
    fueling a prolonged bull market.  The  anticipated  introduction of a common
    European currency in 1999 and increasing global  competitiveness are driving
    business  and  government   efforts  to  make  European   investments   more
    attractive.

*   The  Japanese  economy  is in  recession  and the Far  East is  experiencing
    significant  contractions in manufacturing output and consumer spending. The
    region is faced with addressing a high percentage of bad loans and overbuilt
    manufacturing capacity.

*   Despite the serious  economic  problems  in Asia and  Russia,  many  foreign
    markets  should  continue  to provide a source of both  positive  investment
    returns and diversification for U.S.-based investors.

MANAGEMENT Q&A

*   VP  International  shares  returned 25.30% for the six months ended June 30,
    1998 compared with 15.93% for the Morgan Stanley Capital  International EAFE
    Index, the fund's benchmark.

*   A greater  exposure  to  European  stocks and a lighter  weighting  in Asian
    companies  relative to the  benchmark  explains  much of the  difference  in
    performance.

*   Banking,   financial   services,   computer   software   and   services  and
    communications  services  companies were among the best performing  industry
    groups in the  portfolio.  All are  benefiting  from  economic  momentum  in
    Europe.

*   Among the  significant  changes  in the  portfolio  during  the  period  was
    increased exposure to cellular and telecommunications  companies, which have
    been experiencing rapid expansion in the face of strong consumer demand.

*   VP  International's  exposure to Asian  companies was cut back last year and
    was reduced further during the six months ended June 30. We will continue to
    evaluate  the  Asian  situation  and  expect to be there  when the  earnings
    picture begins to improve.

Market Perspective from Bob Puff
- --------------------------------------------------------------------------------

[photo of Bob Puff]
Bob Puff, chief investment officer of American Century Investments

DIVERSITY IS STILL THE RULE

     The behavior of  international  equity  markets during the six months ended
June 30  demonstrates  not only the extent of the  decoupling  of  domestic  and
foreign  markets,  but also the difference in performance  among foreign markets
themselves.  It also shows that it is  possible to produce  positive  investment
results even in a turbulent global economic environment.

     The chart on this page points out the  difference  among returns in Europe,
the U.S.,  and the Far East.  The  mature  European  markets  showed  impressive
strength.  Meanwhile,  the much publicized crisis in Asia, which migrated to the
developing  economies of Eastern Europe and Latin America,  was  responsible for
weak performance in these regions.

A BRIEF LOOK BACK

     In the late 1980s,  the prevailing  wisdom was that  international  markets
carried more risk than domestic equities.  International  investment was seen as
risky for several reasons:

*   Foreign currencies were volatile.

*   The  availability  of  accurate  and useful  information  on  non-U.S.-based
    companies was extremely limited.

*   Accounting  standards  in use around the globe were not  comparable  to U.S.
    standards  or were often not  understandable  to investors in other parts of
    the world.

*   There were  legitimate  questions  about  regulatory  issues and whether the
    proper disclosure  requirements were in place--something U.S. investors take
    for granted.

*   U.S. regulators  encouraged mutual fund companies to put international funds
    on the aggressive end of the risk spectrum.

*   Finally,  foreign  investments  were  thought to hold  additional  political
    risks, especially in developing countries.

     Ten years  later  these  issues are still with us, but the  emergence  of a
global  economy and the desire of countries to  participate in the post-Cold War
economic  boom have brought  about  significant  improvements.  In a world where
Coca-Cola  derives  most of its profits  from  foreign  customers  and  European
companies like  pharmaceutical  giant Novartis advertise  regularly in the U.S.,
there is a lot riding on global interdependence.

     But  foreign  companies  are not  coming  to the U.S.  just to tap into our
powerful  consumer  base.  They are also  looking  for  capital  to build  their
businesses.  To obtain that capital they are increasingly  being asked to reform
and clarify their accounting  standards.  The search for capital and the growing
professionalism in the investment  management business around the world are also
prompting  corporations  to raise their  standards for the release of pertinent,
shareholder-relevant information.

Market Perspective (continued)
- --------------------------------------------------------------------------------

     Countries are being asked to put in place policies that will help stabilize
their economies and currencies, and encourage foreign investment.

     These trends are by no means  uniform  around the globe,  but they are more
widely in evidence, especially in Europe.

EUROPE AT THE THRESHOLD

     There has been a powerful  bull market in Europe for several  years now, as
the  Continent  prepares for the start of the European  Monetary  Union (EMU) in
1999. Supporting the European equity rally was a substantial decline in interest
rates.  On the  corporate  front,  Europe  has made great  progress.  Accounting
standards are improving. Companies are consolidating to meet global competition,
buying  back  their  own  stock  and  tying  management  compensation  to  stock
performance,   which  tends  to  align  management's  interests  with  those  of
shareholders.   European   governments   continue  to  privatize--to   sell  off
corporations they once controlled to the private sector.

     Although tax rates in Europe remain high,  they could decline after the EMU
is in place.  This,  along  with more  equity-oriented  savings  and  retirement
practices--similar   to  those  we  have  seen  in  the  U.S.  during  the  last
decade--should encourage investment.

THE ASIAN RECESSION

     Recent  events  in  Asia  have  taken a  serious  turn.  Japan  is now in a
recession,  and there have been major  contractions in manufacturing  output and
consumer spending  throughout the Far East. Whereas mergers and market expansion
are  the  rule  in  Europe,  companies  in  Asia  are  often  merging  to  avoid
liquidation.  The region remains awash in bad loans and overbuilt  manufacturing
capacity.  Credit  is  now  extremely  tight--after  years  of  being  abundant.
Political  confrontation is also a concern.  Many of the changes that could pull
Asia out of its current crisis are cultural,  as opposed to simply economic,  so
reforms may take longer to effect.

RISK AND FOREIGN INVESTING

     The  contrast  between the  ongoing  Asian  economic  crisis and the strong
markets of Europe  suggests that major global economic events in one part of the
world  do not  always  have  an  impact  on  other  foreign  markets.  No one is
downplaying the seriousness of what has happened in Asia and the recent economic
and political events in Russia. But unless these events unfold into a full-scale
global  recession,  which does not seem likely given the good health of the U.S.
and European economies, many foreign markets should continue to provide a source
of  both  positive   investment  returns  and   diversification  for  U.S.-based
investors.

VP International--Q&A
- --------------------------------------------------------------------------------

     An interview  with Henrik Strabo and Mark Kopinski,  portfolio  managers on
the VP International team.

VP  INTERNATIONAL  PERFORMED VERY WELL DURING THE FIRST SIX MONTHS OF ITS FISCAL
YEAR. IT HAS BEEN AMONG THE BETTER PERFORMING  INTERNATIONAL  FUNDS FOR THE LAST
THREE YEARS. WHAT ARE SOME OF THE REASONS FOR THE STRONG RETURNS?

     While we do not invest the portfolio with a specific  index in mind,  we're
gratified that our investment approach again allowed us to outperform the Morgan
Stanley Capital International EAFE Index for the six months ended June 30, 1998.
VP  International  returned 25.30% for the period,  compared with EAFE's 15.93%.
For the 12 months  ended  June 30, VP  International  was up  25.12%,  more than
quadruple  the EAFE  index  return of  6.10%.  The  three-year  return of 22.43%
doubled the 10.69% for EAFE.

     Relative to EAFE, VP International had more exposure to European stocks and
a lighter weighting in Asian companies, which largely explains the difference in
performance.

     VP  International  has also  performed  much better than most foreign stock
funds during the six months.  According to Lipper  Analytical  Services  Inc., a
major  independent  mutual fund research firm, VP International  finished in the
top 5% of 110  international  funds for the six months  ended June 30 and in the
top 7% of 104 funds for the 12 months  ended June 30. For the three  years ended
June 30, VP International was in the top 9% of 68 international funds.(+)

     We believe our success in the current uncertain global economic environment
is  attributable to our  disciplined  investment  style of focusing on companies
whose  earnings  are growing at an  accelerating  rate.  As we  discussed in the
annual  report six months ago, this  approach  pointed us toward faster  growing
European businesses and away from slower growing companies in Asia and Japan.

     Although we are currently heavily invested in Europe,  our investment style
is not guided by factors such as country or sector  weightings.  The  investment
team  continually  monitors  such macro  factors as a  country's  political  and
economic  stability,   but  our  primary  strategy  is  to  own  companies  with
accelerating revenues and earnings regardless of where they are located.

WHAT WERE SOME OF THE HOLDINGS THAT CONTRIBUTED MOST SIGNIFICANTLY TO RETURNS?

     Among the best  performing  industry  groups in the portfolio were banking,
financial services,  computer software and services, and communications services
companies. We were able to find many companies from among these groups in Europe
where  evolving   economic   trends  are  starting  to  transform  the  business
environment.

     The  introduction  of a single currency in 1999,  corporate  restructuring,
privatization,  industrial  modernization,  strong  consumer  demand,  labor and
pension  reform and a renewed  focus by corporate  management on the bottom line
are some of the forces at work in Europe.

     Nowhere in the  European  modernization  movement  are these  factors  more
apparent than in the communications industry.

VP International--Q&A (continued)
- --------------------------------------------------------------------------------

firm, is one of the leading providers of cellular  telephone service in Germany.
As one of the largest holdings in the portfolio,  Mannesmann  represented  about
2.5% of investments at June 30 and was one of our best  performing  stocks.  The
extraordinary  popularity of cellular  service across the European  continent is
largely responsible for Mannesmann's performance. Many investors started to pull
back from some of the cellular service  providers early this year,  feeling that
market  penetration  could not expand much more. But cellular  subscriptions  in
Europe  continue  to grow at a  surprising  rate.  This  growth in the  cellular
business has helped fuel Mannesmann's earnings progress.

     While several new telecom  ventures have been started in Europe in the last
year, Mannesmann's established mobile and fixed facility service in Germany, and
smaller  operations in France and Italy,  position the company to become a major
competitor  in the  expanding  European  communications  business.  In addition,
Mannesmann's  once  unprofitable   engineering  division  has  also  started  to
contribute to earnings.  Other strong  contributors from the  telecommunications
and cellular group include Alcatel Alsthom, Nokia, and Ericsson Telephone.

     Referring  to the chart on the right you will see that  financial  services
was the largest  industry  holding in the portfolio at 12.6% of investments.  It
was also one of the best performing  groups.  Europe's  changing attitude toward
the   investment  of  personal   savings  means   financial   institutions   are
well-positioned  to  take  advantage  of  the  growing  interest  in  retirement
planning.   Financial  service   institutions  are  starting  to  offer  updated
investment  products as  individuals  seek to shift out of  traditional  savings
vehicles and into investment-oriented products.

     Some of the top performing  financial  services names in the portfolio were
ING Groep N.V., Julius Baer Holding AG, Banca Intesa SPA, and AMVESCAP.

     Pension  modernization is also stimulating  demand for mutual funds,  which
have been largely  unavailable in Europe until recently.  As a result, the asset
management  business  is  starting to see  significant  inflows,  similar to the
United States in the early 1980s.

     Julius Baer  Holding  AG, a  Swiss-based  private  banking  concern  with a
substantial  asset  management  capability,  represented  more  than  2% of  the
portfolio at the end of the period. Banca Intesa SPA is one of the largest asset
managers in Italy,  a country  where cash flows into mutual funds have been very
strong.  AMVESCAP,  another  major asset  manager,  has a global  reach,  having
recently  acquired LGT Asset  Management and AIM  Management  Group in 1997. The
European  mutual fund business has the potential to  experience  similar  growth
rates to the U.S. fund business over the past 20 years.

WERE THERE ANY STOCKS THAT DIDN'T DO AS WELL AS YOU HAD EXPECTED?

     In general,  commodity-based companies, including energy and chemicals, did
not do well.  Asian  economic  problems and the worldwide  decline in oil prices
hurt the energy exploration and production companies in the portfolio.  The drop
in oil prices and the fall-off in demand  affected  several  energy  exploration
companies, including British-Borneo Petroleum,  Transocean Offshore and Woodside
Petroleum LTD.

VP International--Q&A (continued)

     Takeda  Chemical  also  was  down  after  earnings   dropped   following  a
restructuring of the government-controlled pharmaceutical pricing framework.

DID YOU  MAKE ANY  SIGNIFICANT  CHANGES  TO THE  PORTFOLIO  DURING  THE LAST SIX
MONTHS?

     As  mentioned  earlier,  we  made a  significant  move  into  cellular  and
telecommunications   companies.  After  reducing  holdings  in  Nokia,  Phillips
Electronics,  Ericsson and Alcatel at the onset of the Asian economic  crisis in
mid-1997,  we moved back into  these  names this  year.  Cellular  order  growth
continued  to expand and demand for  cellular  services  at the  consumer  level
remained  high.  Moreover,  our  analysis  indicated  earnings  continued on the
upswing.  We were able to build  positions  in these  growth  companies at lower
prices and then saw them move back beyond their 1997 highs.

     We  also  reduced  holdings  in  Novartis  AG to  less  than  2%  of  total
investments from 3.7% six months ago because of a slowdown in earnings growth.

DO YOU EXPECT TO MAKE ANY PORTFOLIO  ADJUSTMENTS,  GIVEN THAT THE ASIAN ECONOMIC
CRISIS IS THE DOMINANT FACTOR IN THE INTERNATIONAL INVESTMENT PICTURE?

     VP  International's  exposure to Asian  companies had already been cut back
last year and was reduced further during the six months.

     As mentioned  earlier,  our  bottom-up  investment  process led us to focus
primarily on European  companies at a time when Asian  companies began to suffer
from  economic  deterioration.  Business  fundamentals  have been  improving  in
Europe, economies are accelerating and earnings and profit surprises are largely
on the positive side.  Almost exactly the opposite is generally the case in Asia
right now.

     The fact that we, and many others,  are not currently  investing heavily in
Asian and Pacific Rim markets  doesn't mean we aren't looking there. We continue
to  evaluate  the  situation  and expect to be there in a  responsible  way once
earnings start to grow or a positive  catalyst  emerges to brighten the earnings
outlook.

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 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.  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 out by capital (money invested by shareholders);  net
investment  income not yet paid to  shareholders or net investment  losses;  net
gains  earned on  investments  not yet paid to  shareholders  or net losses from
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  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.

JUNE 30, 1998 (UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION   --  American   Century   Variable   Portfolios,   Inc.  (the
Corporation)  is  registered  under  the  Investment  Company  Act of 1940 as an
open-end  diversified   management  investment  company.   American  Century  VP
International  (the  Fund)  is one of the six  series  of  funds  issued  by the
Corporation.  The Fund's investment  objective is capital growth. The Fund seeks
to achieve its investment objective by investing primarily in an internationally
diversified  portfolio of equity securities that are considered by management to
have prospects for appreciation. The Fund will invest primarily in securities of
issuers  located in developed  markets.  The  following  significant  accounting
policies,  related  to the Fund,  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.  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 Fund 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
portfolio  securities,  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 portfolio
securities  and other  assets  and  liabilities  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  foreign   currency   transactions   and   unrealized
appreciation  (depreciation) on translation of assets and liabilities in foreign
currencies, respectively.

     FORWARD  FOREIGN  CURRENCY  EXCHANGE  CONTRACTS  -- The Fund 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 Fund's  exposure  to  foreign  currency  exchange  rate  fluctuations.  When
required,  the Fund will segregate  assets in an amount  sufficient to cover its
obligations  under the hedge  contracts.  The net U.S.  dollar  value of foreign
currency  underlying  all  contractual  commitments  held  by the  Fund  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 Statement of Assets and  Liabilities.  The
Fund bears 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 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 equal to or greater than amounts
owed to the Fund under each repurchase agreement.

     INCOME TAX STATUS -- It is the policy of the Fund to distribute all taxable
income and 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.

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

JUNE 30, 1998 (UNAUDITED)

     DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded
on the  ex-dividend  date.  Distributions  from net  investment  income  and 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.  These
differences  are  primarily  due to differing  treatments  for foreign  currency
transactions  and wash sales 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.  These estimates and assumptions  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 a Management  Agreement  with ACIM that
provides the Fund with investment  advisory and management  services in exchange
for a single, unified fee. The Agreement provides that all expenses of the Fund,
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  Purchases  and  sales  of  investment
securities,  paid monthly  based on the Fund's  average daily closing net assets
during the previous month. The annual management fee for the Fund is 1.50%.

     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.

- --------------------------------------------------------------------------------
3. INVESTMENT TRANSACTIONS

     Purchases  and  sales  of  investment   securities,   excluding  short-term
investments,  totaled $350,940,067 and $230,026,702,  respectively.  On June 30,
1998,  accumulated net unrealized  appreciation on investments was  $77,128,263,
based on the aggregate  cost of  investments  for federal income tax purposes of
$344,927,082,  which  consisted of unrealized  appreciation  of $81,251,929  and
unrealized depreciation of $4,123,666.

Background Information
- --------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY  AND POLICIES

     The  philosophy  behind  American  Century's  growth funds focuses on three
important principles. Chiefly, the funds seek to own successful companies, which
we define as those whose  earnings  and  revenues  are  growing at  accelerating
rates. In addition,  we attempt to keep the funds fully invested,  regardless of
short-term market activity.  Experience has shown that market gains can occur in
unpredictable  spurts  and that  missing  even some of these  opportunities  may
significantly  limit  potential for gain.  Finally,  American  Century funds are
managed by teams,  rather than by one "star" manager. We believe this enables us
to make better, more consistent management decisions.

     VP INTERNATIONAL'S investment objective is capital growth. The fund invests
primarily  in  the  equity   securities  of  foreign   companies   that  exhibit
accelerating earnings growth. It favors companies based in developed markets. It
will typically have significant share price fluctuations.

     International   investing   involves  special  risks  including   political
instability and economic risk.

HOW CURRENCY RETURNS AFFECT  FUND PERFORMANCE

     For U.S. investors, the total return from international stocks includes the
effects of  currency  fluctuations  -- the  movement of  international  currency
values in relation to the value of the U.S. dollar. Currency exchange rates come
into play when international  stock income,  gains and losses are converted into
U.S. dollars.

     Changing currency values may have a significant impact on the total returns
of  international  stock  funds.  The value of the foreign  investments  held by
international  stock  funds may be reduced or  increased  by changes in currency
exchange rates. The U.S. dollar value of a foreign security generally  decreases
when the value of the dollar  rises  against the  foreign  currency in which the
security is  denominated.  This  tended to be the case in 1997,  when the dollar
increased in value against most major foreign currencies.  (The weakened foreign
currencies bought fewer dollars.) Conversely, the U.S. dollar value of a foreign
security  tends to  increase  when the value of the  dollar  falls  against  the
foreign  currency.  (The  stronger  foreign  currency  buys  more  dollars.)  In
addition,  the value of fund assets may be affected by losses and other expenses
incurred in converting  between U.S. dollars and various  currencies in order to
purchase and sell foreign securities.  Currency  restrictions,  exchange control
regulations,  currency  devaluations and political  developments may also affect
net asset value.

COMPARATIVE INDICES

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

     MORGAN STANLEY CAPITAL  INTERNATIONAL  (MSCI) has developed several indices
that measure the  performance  of foreign stock  markets.  The best known is the
EUROPE, AUSTRALASIA,  FAR EAST INDEX (EAFE), which is a widely followed group of
stocks from 20 countries.  Within this index are two narrower indices.  The MSCI
EUROPE measures stock  performance in 14 European  countries.  The MSCI FAR EAST
measures stock performance in Japan, Hong Kong, Malaysia and Singapore.

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  year-by-year  results.
For year-by-year  total returns,  please refer to the "Financial  Highlights" on
page 18.


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.

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 turn,  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 & As with fund managers.
We  hope  the  new  design  will  make  the   reports   more   interesting   and
understandable,  and easier for you to 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 ones. They 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.

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

     We've  been  optimistic  about the  financial  markets  for many  years and
continue to think that common  stocks will produce  attractive  returns over the
long run. Many companies have re-thought their basic strategies,  improved their
operating  performance  and are generating  impressive  returns on  investments.
While the economic  crisis in the Far East has affected  earnings in a number of
areas, the U.S. economy continues to be in good condition.

     Despite the run up in the stock  market over the past  several  years,  not
every single company has  participated  in the market's  appreciation.  The very
best  performers have been among the country's  largest  companies -- those with
strong, established credentials and predictable earnings streams. Many small and
midsized businesses have lagged behind. This has been problematic for VP Capital
Appreciation  because the  majority of its  holdings are focused on midsized and
smaller firms where we think the long-term growth  potential is exceptional.  We
think this would be the wrong time to abandon  the fund's  mid-cap  strategy  in
order to chase the shares of larger  companies,  which are now relatively richly
priced.

     Another matter involving VP Capital Appreciation that has been discouraging
is our portfolio team's execution of our long-held,  growth-oriented strategies.

MARKET PERSPECTIVE

o    The S&P 500 has continued  its steep ascent.  For the six months ended June
     30, 1998, it returned  17.66%.  Calendar  1995-1997  marked one of the best
     three-year performance runs on record.

o    Mid-cap  and  smaller  stocks  performed  well,  with  the S&P  MidCap  400
     returning 8.63% and the Russell 2000 gaining 4.93%.

o    A robust  economy,  minimal  inflation and low  unemployment  are among the
     factors driving the economy.  U.S.  companies are enjoying  extraordinarily
     high  profitability  as they  make  gains  in  productivity  and the use of
     technology. A wave of mergers has also increased efficiency and profits.

o    Stock prices are at historically high levels when measured against earnings
     growth, book value and dividend yield.

o    A favorable  environment for stocks could shift with a rise in inflation or
     interest rates. That does not appear imminent due to the economic-dampening
     effects of the financial crisis in the Far East.


MANAGEMENT Q&A

o    VP Capital  Appreciation  was flat for the period,  with a total  return of
     0.88%. Its benchmark, the S&P MidCap 400, gained 8.63%.

o    The fund had a large weighting in technology and energy services  companies
     early in the period.  These sectors retreated on news of expanding economic
     problems  in Asia.  The fund  also was  underexposed  to some  areas of the
     economy where performance was strong, particularly financial services.

o    The  fund's  benchmark,   although  mid-cap  by  name,  owed  much  of  its
     performance to stocks that are no longer in the mid-cap arena.

o    A new team, led by portfolio  managers  Harold Bradley and Linda  Peterson,
     assumed  responsibility for the fund in April. The team's first step was to
     increase the fund's  diversification,  gaining  exposure to more industries
     where earnings acceleration was evident.

o    Secondly,  the team reallocated fund investments away from stocks with high
     absolute growth rates. Instead, the team has focused on stocks whose growth
     rate is  changing  at a rapid  pace,  even if the  absolute  growth rate is
     modest.

Market Perspective from Bob Puff
- --------------------------------------------------------------------------------

Bob Puff, chief investment officer of American Century Investments

A POWERFUL UPSLOPE

     Just how quickly has the stock market  appreciated over the past few years?
It took  approximately 16 years,  from 1970-1985,  for the Standard & Poor's 500
Index to double.  Only six years later,  it had doubled again,  and roughly five
years after that,  in early 1997, it had doubled once more, to 800. As the chart
on this page illustrates, the S&P 500's recent climb has been very steep. At the
end of June 1998, the index was over 1100.

     Looked at another way, calendar 1995-1997 marked one of the best three-year
performance  runs on record.  It was, in fact, the most  consistent  performance
ever for  large-stock  indices  such as the S&P 500. All three years saw returns
top 20%. During the six months ended June 30, the S&P 500 barely paused to catch
its breath, gaining 17.66%.

     Lower  corporate  earnings,  a tight U.S.  labor  market,  and the  ongoing
economic  crisis in Asia caused only minor pullbacks in late 1997 and the second
quarter of 1998.

A POWERHOUSE ECONOMY

     Stocks  owe  much  of  their  success  to a  robust  economy  with  minimal
inflation.  The U.S. economy is currently  demonstrating a vigor we haven't seen
in a generation.

o    U.S.  economic  growth  hit 3.8% in 1997 and 5.5% in the first  quarter  of
     1998.

o    Inflation was a mere 1.4% for the 12 months ended June 30, 1998.

o    In 1997, prices rose at the slowest pace in 12 years.

o    Interest rates are among the lowest since the 1960s.

o    Unemployment in 1997 was the lowest in 28 years.

o    The U.S. government is projecting the first budget surplus in 30 years.

     A successful  market is also tied to the success of  individual  companies.
Earnings growth and productivity  are at the top of the business agenda.  We are
among the most  technologically  proficient of the industrial nations,  and as a
result, U.S. companies are enjoying  extraordinarily high profitability.  A wave
of mergers,  often  involving  such  high-profile  names as Travelers  Group and
Citicorp, has, in general, increased efficiency and boosted profits.

     In 1997 and the first  quarter of 1998  earnings  growth  slowed,  but only
after a  double-digit  growth  spurt that lasted five years.  Given the positive
business climate,  it's not surprising stocks remain such a popular  investment,
and that cash continues to flow into the market at record volumes.

     However,  by some  traditional  measures,  stock prices are expensive.  The
average stock in the S&P 500 now costs more than 25 times last year's  earnings,
a historical high. Corporate

Market Perspective (continued)
- --------------------------------------------------------------------------------

assets are also richly  valued.  Investors are paying roughly five times balance
sheet assets, or twice the historical average. The dividend yield on the average
S&P 500 stock has fallen to less than 1.5%, another record.

BIG WAS BETTER

     As the accompanying chart makes clear, large companies (as reflected in the
S&P 500) continued to outperform  midsize and small  companies in the first half
of 1998.  Leadership  has been  narrow.  The  largest 100 stocks in the S&P 500,
measured by market value,  have hugely  outdistanced  the remaining 400. And the
very largest -- GE,  Coca-Cola,  Microsoft,  and other  household  names -- have
posted the  biggest  gains.  The "mega  stocks"  are in vogue  because  they are
liquid, that is, easier to trade in large quantities. In theory, their liquidity
should make them easier to exit if the stock market slips.  The fascination with
size has been  prevalent  for several  years.  It was also in vogue a generation
ago, in the early  seventies,  when the "Nifty Fifty"  (companies that were also
household names) provided the performance fireworks.

EARNINGS, INFLATION, AND  INTEREST RATES

     What  could  make the world  less  equity-friendly  -- no  matter  what the
company's size? Most probably,  an upturn in inflation or a substantial  decline
in earnings.  You don't have to look farther than the second  quarter,  when the
Asian crisis threatened  earnings and the Federal Reserve hinted a rate hike was
possible.  In late 1997,  the spike in oil prices,  combined  with the deepening
Asian crisis,  also raised the specter of higher inflation and lower earnings --
and stocks fell back.

     If  inflation  picks  up,  interest  rates are  likely to rise too,  as the
Federal  Reserve  Board tries to head off  inflation  by pushing  rates  higher.
Higher  interest  rates  increase  the  cost of  borrowing  for  everyone,  from
corporations to prospective  home buyers,  and thus tend to slow economic growth
and dampen inflation.

     In 1997, inflation failed to take off. Oil prices went into a tailspin when
Asian  demand  fell.  In early 1998,  as crude oil prices hit a  nine-year  low,
interest  rates  declined  and stocks  soared even though the fallout  from Asia
still threatened to slow both corporate earnings and U.S. economic growth.

     This is a resilient  market.  Its long-term  prospects are still favorable.
But investor  expectations are running high, which is reflected in the S&P 500's
steep climb over the last three and a half years.  In this  environment,  stocks
could prove vulnerable to disappointments.

VP Capital Appreciation--Q&A
- ---------------------------------------------------------------------------

     An interview with portfolio managers Harold Bradley and Linda Peterson, who
assumed management of VP Capital Appreciation in April.

HOW DID THE FUND PERFORM DURING THE SIX MONTHS ENDED JUNE 30, 1998?

     VP Capital  Appreciation  was flat for the period,  with a total  return of
0.88%. Its benchmark, the S&P MidCap 400, gained 8.63%.

     The fund's poor performance,  in both absolute terms and in relation to its
benchmark, can be largely explained by its overemphasis on oil service companies
and its  underexposure to financial  services.  Companies in the energy services
field  experienced  declines as the Asian recession  dampened demand for oil. On
the other hand,  financial stocks climbed as good earnings,  low interest rates,
strong  consumer  credit  quality  and  industry  consolidation  boosted  profit
margins.

     It is also worth noting that the stocks driving the  performance of the S&P
MidCap 400 are actually  beyond the definition of mid-cap,  which  traditionally
falls between $1 billion and $5 billion in total market  capitalization.  Of the
top 14 contributors to the S&P 400's performance  during the period, 11 exceeded
$5 billion.  America  Online,  for  example,  finished  the period with a market
capitalization  of $26 billion.  As a mid-cap fund, VP Capital  Appreciation was
held back at a time when the market favored larger stocks.

CAN YOU TELL US MORE ABOUT THE NEW TEAM?

     We also manage another mid-cap fund, Twentieth Century Heritage.  Harold is
a member of American Century's  investment oversight committee and has been with
the company 10 years, much of it spent as head of the trading department.  Prior
to joining the fund's  investment team, he guided a two-year  research effort on
how to refine and optimize the company's earnings acceleration discipline. Linda
joined the company in 1986.  She was an investment  analyst on Heritage for four
years before becoming a portfolio manager on that fund early this year.

WHAT ARE YOU DOING TO TURN PERFORMANCE AROUND?

     VP Capital Appreciation's returns are not up to either our shareholders' or
American Century's expectations, and we have taken steps in an effort to get the
fund on track. Our first step was to increase the fund's  diversification across
industries. We lowered the weighting in technology, increased financial services
and added exposure to new areas where earnings acceleration was evident, such as

VP Capital Appreciation--Q&A (continued)

sented outperformed the market and when overweighted sectors, such as technology
and energy services, were hit with bad news.

     Our  second  step was to  reemphasize  our focus on  earnings  and  revenue
acceleration  instead of high absolute  growth.  A company with three successive
quarterly  earnings growth rates of 5%, 7% and 11% is more attractive to us than
one growing at 50%, for example, but not showing consistent  improvement quarter
to quarter.  The market has shown a preference  for stocks that can  demonstrate
steady  improvement in earnings  growth rates over those that have high absolute
growth rates and high  valuations  but may be vulnerable to steep price declines
if the growth rate falters.

     The strategy  shift  represents a  reemphasis  on the classic  acceleration
model  developed by American  Century  founder James  Stowers,  Jr., and refined
using additional  computer  analysis.  We are using this more refined  portfolio
construction  model to help us  identify  companies  that meet our  accelerating
earnings and revenue growth criteria.  The model also aids in diversification by
helping  to  identify  all  industries  where  the  proportion  of  accelerating
companies is highest.  It helps remove  biases that may favor one industry  over
another.

     As a measure  of this  strategy  shift,  you will see from the chart to the
right that the two largest  weightings at June 30, 1998,  computer  software and
services and  pharmaceuticals,  totaled  17.8%.  Six months  earlier,  two other
groups,  energy  services  and retail  (general  merchandise),  were our largest
investments and represented 23.4% of fund investments.

IS THIS STRATEGY WORKING?

     We have been very pleased with the performance of the stocks that have been
added to the portfolio. New names, such as Owens Corning, Network Associates and
Life Re Corp., have performed very well.  However,  gains from these stocks were
offset by losses on companies that have mostly been  eliminated.  In the future,
we expect the increased diversification will allow participation in market gains
that VP Capital Appreciation failed to capture using a more targeted approach.

AS YOU HAVE  REALLOCATED  HOLDINGS,  WHICH STOCKS OR SECTORS HAVE YOU FOUND MOST
ATTRACTIVE?

     Financial  stocks  have more than  doubled  to 15% of the  portfolio.  This
group,  which  includes  banks,  savings and loans and insurance  companies,  is
benefiting  from  declining  interest  rates and  consolidation  among  regional
players.  One of our largest  holdings in this area is Life Re Corp., a life and
property  reinsurer.   Life  Re  assumes  some  of  the  risks  associated  with
underwriting  insurance policies.  The company is benefiting from a trend in the
insurance industry toward issuing shares to the public rather than maintaining a
mutual ownership structure.  As these companies go public, they look for ways to
increase profitability to reward their shareholders.

     Another shift we are excited about is our new  investment in  international
stocks,  which  reached 9.5% at June 30,  1998.  The decision by 11 countries to
band  together  to form the  European  Monetary  Union  has  created a wealth of
opportunities for many companies

in  those  countries.  We have  focused  on  banks  as  being  among  the  chief
beneficiaries of the new union. European banks are behind the U.S. in undergoing
a wave of consolidation,  which has both short- and long-term benefits for stock
prices as banks become more efficient and more profitable.  In addition,  demand
for bank products and services is mushrooming as Europeans  increasingly look at
new ways to finance retirement.

     In terms of individual stocks,  Owens Corning's strong performance has been
driven by a robust  housing  market.  Low interest rates have boosted the demand
for new  houses,  thereby  boosting  revenues  from Owens  Corning's  fiberglass
insulation and roofing products.

     Another contributor was Network Associates, which sells software to protect
computer networks from viruses. The company has established itself as a supplier
of a full line of anti-virus, network security and network management tools.

WHICH INDIVIDUAL STOCKS HURT PERFORMANCE MOST DURING THE PERIOD?

     Premiere Technologies was the worst performer.  The company, which provides
voice  mail,  conference  calling  and  Internet-based  communication  services,
announced  June 10 that two  large  customers  were  delinquent,  requiring  the
company to set up cash reserves against those accounts.  The company's  earnings
dropped and its stock was  punished by a market  that has had no  tolerance  for
earnings disappointments.

     ITEQ Inc. was second on the list of detractors. The market reacted strongly
to news that the company  would not pursue a planned  acquisition  in Australia.
ITEQ makes equipment used in the processing of natural gas and other pressurized
liquids.

WHAT IS YOUR OUTLOOK FOR VP CAPITAL APPRECIATION?

     We are optimistic that VP Capital  Appreciation's  performance will benefit
from  the new and  more  advanced  portfolio  construction  models  we  recently
adopted.  These models help us pick the best companies using a more  diversified
approach.  The mid-cap universe is an exciting area in which to apply this model
because we are able to catch  acceleration  early in underfollowed  names within
this universe. We are confident we can provide good performance with appropriate
diversification.

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 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.  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
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   breakout   tells  you  the  value  of  assets  that  are
performance-related,  such as income and  investment  gains or  losses,  and the
value of  assets  that  are not  related  to  performance,  such as  shareholder
investments and redemptions.

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

JUNE 30, 1998 (UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION  --  American   Century   Variable   Portfolios,   Inc.,  (the
Corporation)  is  registered  under  the  Investment  Company  Act of 1940 as an
open-end diversified management investment company.  American Century VP Capital
Appreciation  (the  Fund)  is one of the  six  series  of  funds  issued  by the
Corporation.  The Fund's investment  objective is capital growth. The Fund seeks
to achieve its investment objective by investing primarily in common stocks that
are  considered  by  management  to  have   better-than-average   prospects  for
appreciation.  The following  significant  accounting  policies,  related to the
Fund,  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.  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 Fund 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 investments  are a component of realized
gain  (loss)  on  investments  and  unrealized  appreciation  (depreciation)  on
investments, respectively.

     FORWARD  FOREIGN  CURRENCY  EXCHANGE  CONTRACTS  -- The Fund 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 Fund's  exposure  to  foreign  currency  exchange  rate  fluctuations.  When
required,  the Fund will segregate  assets in an amount  sufficient to cover its
obligations  under the hedge  contracts.  The net U.S.  dollar  value of foreign
currency  underlying  all  contractual  commitments  held  by the  Fund  and the
resulting  unrealized  appreciation or depreciation  are determined  daily using
prevailing exchange rates.  Forward contracts involve elements of risk in excess
of the amount  reflected in the  Statement of Assets and  Liabilities.  The Fund
bears 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 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 equal to or 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 or Agency obligations.

     INCOME TAX STATUS -- It is the policy of the Fund to distribute all taxable
income and 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.

Notes to Financial Statements
- --------------------------------------------------------------------------------
                                                                    (continued)

JUNE 30, 1998 (UNAUDITED)

     DISTRIBUTIONS  TO  SHAREHOLDERS  --   Distribu-tions  to  shareholders  are
recorded on the ex-dividend date.  Distributions  from net investment income and
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.  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.  These estimates and assumptions  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 a Manage-ment  Agreement  with ACIM that
provides the Fund with investment  advisory and management  services in exchange
for a single, unified fee. The Agreement provides that all expenses of the Fund,
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 the Fund's  average
daily closing net assets during the previous  month.  The annual  management fee
for the Fund is 1.00%.

     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.

- --------------------------------------------------------------------------------
3. INVESTMENT TRANSACTIONS

     Purchases  and  sales  of  investment   securities,   excluding  short-term
investments, totaled $601,135,260 and $598,842,956, respectively.

     As  of  June  30,  1998,   accumulated  net  unrealized   appreciation  was
$44,376,434,  based on the aggregate cost of investments  for federal income tax
purposes  of  $465,311,189,   which  consisted  of  unrealized  appreciation  of
$63,838,398 and unrealized depreciation of $19,461,964.

Background Information
- --------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY AND POLICIES

     The  philosophy  behind  American  Century's  growth funds focuses on three
important principles. Chiefly, the funds seek to own successful companies, which
we define as those whose  earnings  and  revenues  are  growing at  accelerating
rates. In addition,  we attempt to keep the funds fully invested,  regardless of
short-term market activity.  Experience has shown that market gains can occur in
unpredictable  spurts  and that  missing  even some of those  opportunities  may
significantly  limit  potential for gain.  Finally,  American  Century funds are
managed by teams,  rather than by one "star" manager. We believe this enables us
to make better, more consistent management decisions.

     VP CAPITAL  APPRECIATION  seeks  capital  growth over time by  investing in
growth  companies.   Although  the  fund  may  purchase  securities  across  all
capitalization  ranges,  since mid-1996,  VP Capital  Appreciation  has invested
mainly in the securities of medium-sized firms with accelerating  growth. Such a
strategy  results in volatility over the short term and offers the potential for
long-term growth.


COMPARATIVE INDICES

     The indices  listed  below are used in the report to serve as a  comparison
for the performance of the fund. They are not investment  products available for
purchase.

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

     The S&P MIDCAP 400 is an index created by Standard & Poor's  Corporation of
the 400 leading  companies  not  included in the S&P 500.  It is  considered  to
represent the performance of mid-capitalization  stocks generally. The index was
created in March 1994.  Data  presented  for prior periods have been provided by
S&P.

     The S&P MIDCAP  400/BARRA  GROWTH is an index  created by Standard & Poor's
Corporation and BARRA. The index divides the S&P 400 into two mutually exclusive
groups based on  price/book  ratios.  The half of the S&P 400 with higher ratios
falls into the growth index,  while a value index tracks the  performance of the
other half. Similar growth and value indices are available for the S&P 500.

     The  RUSSELL  2000  INDEX was  created  by the Frank  Russell  Company.  It
measures  the   performance   of  the  2,000   smallest  of  the  3,000  largest
publicly-traded U.S. companies based on total market capitalization. The Russell
2000 represents  approximately 10% of the total market capitalization of the top
3,000 companies. The average market capitalization of the index is approximately
$420 million.

Glossary
- --------------------------------------------------------------------------------

RETURNS

o TOTAL  RETURN  figures  show the overall  percentage  change in the value of a
hypothetical  investment  in  the  fund  and  assume  that  all  of  the  fund's
distributions are reinvested.

o AVERAGE ANNUAL RETURNS  illustrate the annually  compounded returns that would
have produced the fund's cumulative total returns if the fund's  performance had
been  constant  over the  entire  period.  Average  annual  returns  smooth  out
variations in a fund's return;  they are not the same as  year-by-year  results.
For year-by-year  total returns,  please refer to the "Financial  Highlights" on
page 17.

PORTFOLIO STATISTICS

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

o 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.)

o 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.


TYPES OF STOCKS

o  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.

o 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.

o 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.

o 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.

o  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.

o 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 Index.

o 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.

STATISTICAL TERMINOLOGY

o  PRICE/BOOK  RATIO--  a stock  value  measurement  calculated  by  dividing  a
company's stock price by its book value per share,  with the result expressed as
a multiple  instead of as a  percentage.  (Book value per share is calculated by
subtracting a company's liabilities from its assets, then dividing that value by
the number of outstanding shares.)

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

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 & As 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 report  actually  costs slightly less than the old one. They 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 III, seated, with James E. Stowers, Jr.

     Stocks have posted historic  returns over the last few years. The first six
months of the year,  continued  the  momentum,  despite a slowdown in the second
quarter.  The generous  market  values  accorded  many very large,  high-profile
companies  grew even more  generous,  while  midsize and small stocks  turned in
respectable results.

     Fixed-income markets were mixed. Declining interest rates, the search for a
safe haven by many foreign investors, and the improving creditworthiness of U.S.
business  produced a solid market for  Treasurys and other  high-quality  bonds.
Companies  with exposure to Asia,  where economic  troubles have  deepened,  saw
their bonds come under pressure.

     We've been optimistic  about the financial  markets for many years,  and we
continue to believe both stocks and bonds  should  produce fine results over the
long run.  Corporate  America is in good health.  Many companies have cleaned up
their balance  sheets,  are highly  productive,  and are  generating  impressive
returns on products and  investments.  While the economic crisis in the Far East
has affected earnings in a number of areas, our overall economy is sound.

     Despite  the  run-up in  stocks,  not every  company  is  selling at record
prices. We're still in a market of individual  businesses,  and there are plenty
of attractive opportunities that have not been fully recognized. Over the years,
we've been able to blend new technology and resources in a variety of investment
strategies that employ equity and credit  research to find these  opportunities.
Our aim, as always, is to help investors reach their financial goals.

     Finally,  we hope you like the new  design of this  report.  Our annual and
semiannual  reports  contain  a wealth of  information  on fund  strategies  and
holdings.  The new design is intended to make this  information  more accessible
and should encourage you to take a closer look.

     We appreciate your investment with American Century.

Sincerely,

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

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

MARKET PERSPECTIVE

o    After one of the best three-year  runs on record in 1995-1997,  the S&P 500
     barely  paused to catch its breath  during  the six  months  ended June 30,
     gaining 17.66%.

o    Bonds  performed  well  too.  Low  inflation  and  falling  interest  rates
     translated into rising prices in most fixed-income markets.

o    Both stocks and bonds owe much of their  success to a robust  economy  with
     minimal inflation.

o    The success of financial  assets is also tied to the success of  individual
     companies.  Earnings growth has been annualizing at a double-digit rate for
     five of the last six years.

o    However, by some traditional measures, stock prices are very expensive. For
     example,  the  average  stock in the S&P 500 costs  roughly  25 times  last
     year's earnings, a historical high.

o    Our stock and bond markets remain resilient.  But investor expectations are
     running high, which is reflected in the S&P 500's steep climb over the last
     three and a half years.

MANAGEMENT Q&A

o    VP Balanced  gained  14.38% for the six months  ended June 30,  1998.  This
     represents  the  blended  performance  of the  portfolio's  stock  and bond
     components.  Stocks were  approximately  60% of assets,  with the remainder
     invested  in  fixed-income   securities.   VP  Balanced   outperformed  its
     benchmark, which gained 12.02% for the six months.

o    The  stock  portfolio  made  a  significant  contribution  to  performance.
     Standing  alone,  VP  Balanced's  stock  component  was up 22.64%,  handily
     beating the S&P 500's return of 17.66%.

o    Several  pharmaceutical  positions  were  reduced.  Assets  were  moved  to
     financial services, insurance,  telecommunications,  broadcasting,  retail,
     media and cable companies.

o    American   Express  and  SunAmerica  were  among  the  portfolio's   better
     performers.  Tele-Communications,  Inc.  and  Viacom,  two  cable and media
     positions, also did well.

o    The energy  services  industry was weak, and Cendant Corp., a marketing and
     franchising business,  dropped significantly after it discovered accounting
     irregularities at one of its major business units.

o    Though  financial  conditions  were  favorable,  bond  returns  were modest
     compared  with those  enjoyed  by  stocks.  VP  Balanced's  bond  portfolio
     returned 2.57%, similar to interme-diate-term U.S. bond returns in general.

o    Some  attractively  priced  mortgage-backed  securities  were  added to the
     portfolio.  The  higher  yields of the  mortgage-backeds  also  helped  the
     portfolio's  yield, but didn't hurt the average credit rating--it  remained
     AAA.

o    We have decided to change the equity  style of the fund.  (See the attached
     letter.)  We are moving  from the  earnings  acceleration  approach  to our
     proprietary quantitative methodology.

THE  SUCCESS  OF  FINANCIAL  ASSETS IS ALSO TIED TO THE  SUCCESS  OF  INDIVIDUAL
COMPANIES.  EARNINGS  HAVE BEEN GROWING AT A  DOUBLE-DIGIT  RATE FOR FIVE OF THE
LAST SIX YEARS.

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

[photo of Mark Mallon]
Mark Mallon, senior vice president and managing director of American Century
Investments

A POWERFUL UPSLOPE IN STOCKS

     Just how quickly has the stock market  appreciated over the past few years?
It took  approximately 16 years,  from 1970-1985,  for the Standard & Poor's 500
Index to double.  Only six years later,  it had doubled again,  and roughly five
years after that,  in early 1997, it had doubled once more, to 800. As the chart
on page 4  illustrates,  the S&P 500's recent climb has been very steep.  At the
end of June 1998, the index was over 1100.

     Looked at another way, calendar 1995-1997 marked one of the best three-year
performance  runs on record.  It was, in fact, the most  consistent  performance
ever for  large-stock  indices  such as the S&P 500. All three years saw returns
top 20%. During the six months ended June 30, the S&P 500 barely paused to catch
its breath, gaining 17.66%.

     Lower  corporate  earnings,  a tight U.S.  labor  market,  and the  ongoing
economic  crisis in Asia caused only minor pullbacks in late 1997 and the second
quarter of 1998.

THE U.S. BOND MARKET

     Bonds have  performed  well too. Low inflation and falling  interest  rates
have translated into rising prices in most fixed-income markets. Between January
1 and June 30, 1998, the benchmark  30-year  Treasury bond yield fell from 5.93%
to 5.63%.  The 10-year  Treasury note yield,  a benchmark for  intermediate-term
bonds,  dropped from 5.75% to 5.45%.  When yields decline,  bond prices normally
increase.  The  Lehman  Brothers  Intermediate   Government/Corporate  Index,  a
benchmark for  intermediate-term  U.S. government and corporate bonds,  returned
3.47%.

     Bonds  continued  to perform  relatively  well  despite  short-term  market
factors that held back sectors such as corporate and mortgage-backed securities.
Falling  interest rates  triggered a wave of mortgage  refinancing,  which had a
negative effect on mortgage-backed securities. When mortgages are refinanced, it
shortens the life of mortgage-backeds  and forces investors to reinvest at lower
yields.  The Asian crisis  affected the  performance of corporate  bonds because
investors  questioned the financial  health of companies that do business in the
Far East.

A POWERHOUSE ECONOMY

     Both stocks and bonds owe much of their  success to a robust  economy  with
minimal  inflation.  The U.S.  economy  is  currently  demonstrating  a vigor we
haven't seen in a generation.

o    Economic growth hit 3.8% in 1997, and 5.5% in the first quarter of 1998.

o    Inflation was a mere 1.4% for the 12 months ended June 30.

o    In 1997, prices rose at the slowest pace in 12 years.

o    Interest rates are among the lowest since the 1960s.

o    Unemployment was the lowest in 28 years.

o    The U.S. government is projecting the first budget surplus in 30 years.

Market Perspective (continued)
- --------------------------------------------------------------------------------

     The budget surplus means the  government's  borrowing  needs will shrink if
spending doesn't  increase.  The U.S. Treasury has already reduced the amount of
securities  it will issue.  The lower supply of Treasurys  should boost  prices.
Investors  may also  buy more  bonds in  other  sectors  of the U.S.  market  as
Treasurys become scarcer. At the same time, demand should remain strong.  Global
investors  often  turn to U.S.  bonds as a safe haven in times of  political  or
financial unrest.

CORPORATE AMERICA IS HEALTHY

     The success of financial  assets is also tied to the success of  individual
companies.  Earnings  have been growing at a  double-digit  rate for five of the
last six years. We are among the most technologically  proficient and productive
industrial nations, and as a result, U.S. companies are enjoying extraordinarily
high  investment  returns.   Given  the  positive  business  climate,  it's  not
surprising financial assets remain popular investments,  and that cash continues
to flow into the stock market at record volumes.

     However,  by some  traditional  measures,  stock prices are expensive.  The
average  stock in the S&P 500 costs  roughly 25 times last  year's  earnings,  a
historical high.  Corporate assets are also richly valued.  Investors are paying
roughly five times balance sheet assets,  or twice the historical  average.  The
dividend  yield on the  average  S&P 500 stock has fallen  below  1.5%,  another
record.

EARNINGS, INFLATION, AND  INTEREST RATES

     What could  derail  the  financial  markets?  Most  probably,  an upturn in
inflation or a substantial decline in earnings. Late last year, the spike in oil
prices,  combined with the deepening Asian crisis, briefly raised the specter of
higher inflation and lower earnings.  Stocks reacted negatively.  They also fell
back in the second quarter of 1998,  when it appeared the Asian  recession would
cut deep into corporate earnings in the U.S.

     Should  inflation  pick up,  interest  rates are likely to rise too, as the
Federal Reserve adjusts rates upward to slow the economy.  Higher interest rates
increase the cost of borrowing for everyone,  from  corporations  to prospective
home buyers, and thus tend to slow economic growth and dampen inflation.

      In 1997,  inflation  failed to take off.  Oil prices  went into a tailspin
when Asian demand fell. In early 1998, as crude oil prices hit a nine-year  low,
interest  rates  declined and stocks  soared,  even though the fallout from Asia
threatened to slow both corporate earnings and U.S. economic growth.

     Our stock and bond markets remain resilient.  Their long-term prospects are
still favorable.  But investor expectations are running high, which is reflected
in the S&P 500's  steep  climb  over the last  three and a half  years.  In this
environment, financial markets could prove vulnerable to disappointments.

VP Balanced--Q&A
- --------------------------------------------------------------------------------

     An interview  with  portfolio  managers Jim Stowers III, Bruce Wimberly and
John  Sykora  of our  equity  staff,  and Bud  Hoops  and  Jeff  Houston  of our
fixed-income group. They all help oversee the VP Balanced Fund.

WHAT WERE VP  BALANCED'S  RETURNS  FOR THE FIRST HALF OF ITS FISCAL  YEAR ENDED,
JUNE 30, 1998?

     VP Balanced gained 14.38%.  This represents the blended  performance of the
portfolio's stock and bond components.  Stocks were approximately 60% of assets,
with the remainder invested in fixed-income securities. VP Balanced outperformed
its  benchmark,  which gained 12.02% for the same six months.  The blended index
combines the S&P 500 and the Lehman Brothers  Intermediate  Government/Corporate
Bond Index in proportion to the asset mix of VP Balanced's portfolio.

CAN YOU IDENTIFY THE PRIMARY REASONS VP BALANCED OUTPERFORMED ITS BENCHMARK?

     The stock  portfolio made a significant  contribution.  Standing  alone, VP
Balanced's  stock  component was up 22.64% in the first half.  That handily beat
the S&P 500's return of 17.66%. We used American Century's proprietary database,
pricing  screens,  and financial  analysis to find companies and industries with
accelerating revenues and earnings. From this broad menu, we selected individual
businesses whose revenues and earnings growth looked to be sustainable.  We paid
close attention to earnings  visibility:  in other words, we focused  additional
emphasis on companies with recurring revenue streams. We believe these companies
have a higher probability of meeting or beating earnings estimates.

WHY THE EMPHASIS ON VISIBILITY?

     Today the earnings picture is somewhat  clouded because  overall,  earnings
growth slowed in 1997 and in the first quarter of 1998. Many companies that used
to hit earnings targets  regularly are now missing their marks. We believe there
is still a level of optimism  built into earnings  estimates for the second half
of the year. Those  projections are likely to come down. The economic turmoil in
Southeast  Asia  is  hurting  profits  and  revenues  in  many  groups,  such as
technology  and energy,  as are wage  pressures in the U.S. The strong dollar is
also making U.S. merchandise less competitive  overseas.  Foreign buyers have to
pay for our products in their local  currencies,  which become less  valuable as
the dollar rises.

THAT SOUNDS LIKE THE BAD NEWS. WHAT'S THE GOOD NEWS?

     The good news is the U.S. economy. It remains healthy. As always, there are
areas of opportunity.  From our point of view, even the earnings slowdown has an
upside: it creates an environment in which effective stockpicking can really add
value.  We believe that's one of the reasons VP Balanced has generated such good
results over the first six months of 1998.  Our emphasis on earnings  visibility
has worked.

DID THE SEARCH FOR EARNINGS VISIBILITY  TRIGGER CHANGES IN THE PORTFOLIO?

     Yes. We reduced several pharmaceutical positions where the earnings picture
was   fading.    Assets    migrated   to    financial    services,    insurance,
telecommunications,   broadcasting,   retail,  media  and  cable  companies.  In
financial  services we hold  American  Express and  SunAmerica.  Media and cable
companies include

VP Balanced--Q&A (continued)
- --------------------------------------------------------------------------------

Tele-Communications,  Inc.  (TCI) and Viacom.  Both TCI and Viacom are improving
their balance sheets and generating strong cash flow growth.

     We also have high expectations for our retailers. Earnings growth led us to
the  value-conscious  merchandisers--Wal-Mart,  Costco and Dayton Hudson,  which
owns Target  Stores.  We continue to think these  companies  have sound business
models for sustained growth.

WHAT ARE SOME OF THE OTHER ATTRACTIVE GROWTH OPPORTUNITIES YOU JUST MENTIONED?

     We're excited about  telecommunications  and the internet  phenomenon.  The
internet  is bigger  today  than many  people  ever  thought it would be, and we
believe it will  continue  to outpace  expectations.  Companies  such as America
Online (AOL) and WorldCom on the network side and Cisco Systems on the equipment
side have emerged as dominant  providers.  We expect  their market  positions to
improve. AOL, for example, has great earnings visibility. The company collects a
monthly fee from an expanding pool of subscribers. Earlier this year it was able
to raise prices  --something  that has become  fairly rare in our  low-inflation
economy.  WorldCom  is  the  leader  in  providing  commercial  voice  and  data
transmission  internationally.  Its  fiberoptic  network  is  far  ahead  of the
competition's  in an  environment  where  voice  and data  traffic  should  grow
substantially as international commerce becomes increasingly sophisticated.

HOW DID VP BALANCED'S LARGER POSITIONS PERFORM?

     Many  of  our  largest  holdings  were  among  the  best  performers.  Tyco
International,    Clear   Channel   Communications,    American   Express,   and
Tele-Communications,  Inc.  all added  significantly  to  results.  Our  largest
position,  General Electric (GE), was also up  substantially.  GE's earnings per
share  increased by 14% in the first quarter of 1998. The company is pursuing an
aggressive  share-buyback  program  and  has  expanded  its  medical  diagnostic
equipment business by purchasing  Diasonics,  a leading ultrasound imaging firm.
GE is also  shopping for assets in Asia,  where  prices are severely  depressed.
Finally, we took profits in Coca-Cola and drug manufacturer  Pfizer,  which were
among our top ten holdings last year.

WERE THERE ANY DISAPPOINTMENTS OVER THE SIX MONTHS?

     There are always some  underachievers.  The energy  services  industry  was
weak,  and  Cendant  Corp.,  a  marketing  and  franchising  business,   dropped
significantly after it discovered accounting  irregularities at one of its major
business  units.  Cendant  owns such  brand  names as  Ramada,  Howard  Johnson,
Coldwell Banker, Century 21 and Avis.

LET'S TURN TO THE BOND PORTFOLIO. HOW DID IT PERFORM?

     Though  financial  conditions  were  favorable,  bond  returns  were modest
compared with those enjoyed by stocks.  VP Balanced's  bond  portfolio  returned
2.57%, similar to intermediate-term U.S. bond returns in general.

HOW WAS THE BOND PORTFOLIO POSITIONED?

     As a rule,  bonds are owned to provide a performance  cushion for the stock
portfolio.   We  typically  hold  mostly   investment-grade,   intermediate-term
corporate  bonds.  Rather than tinker  much with the  portfolio's  interest-rate
sensitivity, we focus primarily on invest-

ing in  undervalued,  higher-yielding  bond sectors.  In addition to corporates,
higher-yielding  bonds can also include  mortgage-backed  and other asset-backed
securities.

     During the six months,  we sold some of our  corporate  holdings and bought
Treasurys and mortgage-backeds.  With the Asian economic crisis expected to have
an increasing impact on U.S.  corporate  earnings in the second half of 1998, it
seemed prudent to move some money from  corporates to Treasurys.  Treasurys also
typically outperform  corporates when interest rates fall, a possible outcome if
the  Asian  crisis  has  a  significant   impact  on  the  U.S.  We  bought  the
mortgage-backed  securities because they seemed  attractively  priced. A wave of
mortgage  refinancings followed the drop in interest rates in the fourth quarter
of 1997.  The wave of  refinancings  had the effect of driving down the value of
mortgage-backed  securities  and  increasing  their yield relative to other bond
sectors. Mortgage-backeds' higher yields helped offset some of the yield we lost
when we sold corporates for Treasurys.

     Adding the Treasury  bonds and  mortgage-backed  securities,  both of which
have AAA credit  ratings,  caused the overall credit quality of the portfolio to
increase, offsetting any potential exposure to weaker corporate credit ratings

WHAT IS YOUR OUTLOOK FOR BONDS AS WE HEAD INTO THE SECOND HALF OF THE YEAR?

     We're optimistic,  but not completely bullish. What tempers our bullishness
is the underlying  strength of the U.S.  economy,  which might ignite inflation.
Low  unemployment  and high consumer  confidence are forces that could help fend
off any weakness from the economic  recession in Asia. Because of the offsetting
forces of overseas  weakness and domestic  strength,  U.S.  interest  rates have
fluctuated in a relatively  narrow range (with a downward  bias) so far in 1998,
and we expect that to continue.

     Supply and demand fundamentals are still favorable.  The federal government
is running its first budget  surplus in 30 years,  which  reduces  Treasury bond
supply and that in turn exerts more downward pressure on interest rates.

LOOKING AHEAD, WHAT ARE YOUR STRATEGIES FOR VP BALANCED'S STOCK AND BOND
PORTFOLIOS?

     On  the  bond  side,  in  this  low  interest  rate  environment  with  the
possibility  of  increased  economic  weakness,  it's  important to identify and
acquire securities with attractive yields and solid financial  backing.  We will
continue to look for these opportunities.  On the stock side, we have decided to
change the equity style of the fund.  (See the  attached  letter.) We are moving
from  the  earnings  acceleration  approach  to  our  proprietary   quantitative
methodology.  We believe  the new style will  better  meet the  expectations  of
balanced  investors by reducing the  voliatility of the fund's stock  portfolio.
The new style should  continue to produce a diversified  portfolio  that has the
potential for long-term capital growth and current income.

THE UNDERLYING STRENGTH OF THE U.S. ECONOMY, WHICH MIGHT IGNITE INFLATION.

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.  The net assets  divided by the number of
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
investment income not yet paid to shareholders or net investment loss; 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  breakout  tells  you the  value  of net  assets  that  are
performance-related,  such as income and  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, 1998 (UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION  --  American   Century   Variable   Portfolios,   Inc.,  (the
Corporation)  is  registered  under  the  Investment  Company  Act of 1940 as an
open-end diversified management investment company. American Century VP Balanced
(the  Fund) is one of the six  series of funds  issued by the  Corporation.  The
Fund's investment objective is capital growth and current income. The Fund seeks
to achieve its investment objective by investing approximately 60% of the Fund's
assets in common  stocks that are  considered  by management to have better than
average  prospects for  appreciation and the remaining assets in bonds and other
fixed income securities.  The following significant accounting policies, related
to the Fund, 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 Fund 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 investments  are a component of realized
gain  (loss)  on  investments  and  unrealized  appreciation  (depreciation)  on
investments, respectively.

     FORWARD  FOREIGN  CURRENCY  EXCHANGE  CONTRACTS  -- The Fund 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 Fund's  exposure  to  foreign  currency  exchange  rate  fluctuations.  When
required,  the Fund will segregate  assets in an amount  sufficient to cover its
obligations  under the hedge  contracts.  The net U.S.  dollar  value of foreign
currency  underlying  all  contractual  commitments  held  by the  Fund  and the
resulting  unrealized  appreciation or depreciation  are determined  daily using
prevailing exchange rates.  Forward contracts involve elements of risk in excess
of the amount  reflected in the  Statement of Assets and  Liabilities.  The Fund
bears 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.  There were no open
forward foreign currency exchange contracts at June 30, 1998.

     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 equal to or greater than amounts
owed to the Fund under each repurchase agreement.

     JOINT  TRADING  ACCOUNT -- Pursuant  to an  Exemptive  Order  issued by the
Securities and


16   1-800-345-6488


Notes to Financial Statements (continued)
- --------------------------------------------------------------------------------

JUNE 30, 1998 (UNAUDITED)

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  or  Agency
obligations.

     INCOME TAX STATUS -- It is the policy of the Fund to distribute all taxable
income and 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  and 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 realized  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.  These estimates and assumptions  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 a Management  Agreement with ACIM,  that
provides the Fund with investment  advisory and management  services in exchange
for a single, unified fee. The Agreement provides that all expenses of the Fund,
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 the Fund's  average
daily closing net assets during the previous  month.  The annual  management fee
for the Fund is 1.00%.

     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.

3. INVESTMENT TRANSACTIONS

     Purchases  of  investment  securities,  excluding  short-term  investments,
totaled   $148,662,441,   including   purchases  of  U.S.  Treasury  and  Agency

short-term investments,  totaled $105,004,811,  including sales of U.S. Treasury

     As  of  June  30,  1998,   accumulated  net  unrealized   appreciation  was

purposes  of  $235,626,652,   which  consisted  of  unrealized  appreciation  of
$49,496,368 and unrealized depreciation of $1,932,812.

Background Information
- --------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY AND POLICIES

     VP Balanced's investment philosophy focuses on four important principles.

     We attempt  to keep the fund fully  invested  at all times,  regardless  of
short-term market activity.  Experience has shown that market gains can occur in
unpredictable  spurts  and that  missing  even some of those  opportunities  may
significantly limit potential for gain.

     For  the  equity  portfolio,  the  management  team  seeks  to  own  highly
successful  companies,  which we define as those whose earnings and revenues are
growing at accelerating rates.

     For the fixed-income portfolio, "quality first" is the rule. The management
team  seeks only  investment-grade  bonds--those  rated in the top four  quality
categories by nationally recognized statistical rating organizations.

     Each portfolio is managed by a team, rather than by one "star" manager.  We
believe this allows us to make better, more consistent management decisions.

     VP BALANCED seeks to provide  capital growth and current  income.  The fund
keeps  about 60% of its  assets in the stocks of firms  that are  considered  by
management to have better-than-average prospects for appreciation.  Under normal
market conditions,  the remaining assets are held in quality,  intermediate-term
bonds and other fixed-income securities.

COMPARATIVE INDICES

     The indices  listed  below are used in the report to serve as a  comparison
for the performance of the fund. They are not investment  products available for
purchase.

     The BLENDED INDEX is considered the benchmark for VP Balanced.  It combines
two  widely  known  indices  in  proportion  to  the  asset  mix  of  the  fund.
Accordingly,  60% of the index is  represented  by the S&P 500. The remainder of
the index is represented by the Lehman Intermediate  Government/Corporate Index,
which reflects the 40% of the fund's assets invested in intermediate-term  bonds
and other fixed-income securities.

     The LEHMAN  INTERMEDIATE  GOVERNMENT/CORPORATE  BOND INDEX is considered to
represent the performance of a portfolio of  intermediate-term  U.S.  government
and corporate bonds. The index includes the Lehman Government and Corporate Bond
indices,  which are composed of U.S. government,  Treasury and agency securities
with one- to 10-year maturities, as well as corporate and Yankee bonds with one-
to 10-year maturities.

     The  S&P  500  is a  capitalization-weighted  index  of the  stocks  of 500
publicly-traded  U.S.  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.

Glossary

- --------------------------------------------------------------------------------

FIXED-INCOME TERMS

o CREDIT QUALITY  reflects the financial  strength of a debt security issuer and
the likelihood of timely payment of interest and principal.

o DURATION  is a measure  of the  sensitivity  of a  fixed-income  portfolio  to
changes in interest rates. As the duration of a portfolio increases,  the impact
of a change in interest rates on the value of the portfolio also increases.

o STANDARD & POOR'S (S&P) is an independent rating company,  one of the two best
known in the U.S. (the other is Moody's).  The credit  ratings issued by S&P and
Moody's  reflect  the  perceived  financial  strength  (credit  quality) of debt
issuers.  Debt securities rated "investment  grade" (deemed to be of high enough
credit quality to be appropriate  investments for banks and other  institutions)
by S&P are those rated BBB or higher (the highest rating is AAA).

o WEIGHTED AVERAGE MATURITY (WAM),  another  measurement of the sensitivity of a
fixed-income  portfolio to interest  rate  changes,  indicates  the average time
until the  principal  in the  portfolio  is expected  to be repaid,  weighted by
dollar amount.  The longer the WAM, the more interest rate exposure and interest
rate sensitivity the portfolio has.

RETURNS

o TOTAL  RETURN  figures  show the overall  percentage  change in the value of a
hypothetical  investment  in  the  fund  and  assume  that  all  of  the  fund's
distributions are reinvested.

o AVERAGE ANNUAL RETURNS  illustrate the annually  compounded returns that would
have produced the fund's cumulative total returns if the fund's  performance had
been  constant  over the  entire  period.  Average  annual  returns  smooth  out
variations in a fund's return;  they are not the same as  year-by-year  results.
For year-by-year  total returns,  please refer to the "Financial  Highlights" on
page 18.

EQUITY TERMS

o  BLUE-CHIP  STOCKS  --  generally  considered  to be the  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.

o 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.

o GROWTH STOCKS -- generally  considered to be the 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, computer hardware and computer software companies.

o  LARGE-CAPITALIZATION  ("LARGE-CAP")  STOCKS -- generally considered to be the
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,  the S&P 500 and the  Russell  1000
Index.

o  MEDIUM-CAPITALIZATION  ("MID-CAP")  STOCKS -- generally  considered to be the
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.

o 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.)

o  SMALL-CAPITALIZATION  ("SMALL-CAP")  STOCKS -- generally considered to be the
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 Nasdaq Composite Index and the Russell 2000 Index.

o 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.

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 & As 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 report  actually  costs slightly less than the old one. They 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.

     Stocks have posted historic  returns over the last few years. The first six
months of the year  continued  the  momentum,  despite a slowdown  in the second
quarter.  The generous  market  values  accorded  many very large,  high-profile
companies  grew  even  more  generous.   Midsize  and  small  stocks  turned  in
respectable results.

     Fixed-income markets were mixed. Declining interest rates, the search for a
safe haven by many foreign investors, and the improving creditworthiness of U.S.
business  produced a solid market for  Treasurys and other  high-quality  bonds.
Companies  with exposure to Asia,  where economic  troubles have  deepened,  saw
their bonds come under pressure.

     We've been optimistic  about the financial  markets for many years,  and we
continue to believe both stocks and bonds  should  produce fine results over the
long run.  Corporate  America is in good health.  Many companies have cleaned up
their balance  sheets,  are highly  productive,  and are  generating  impressive
returns on products and  investments.  While the economic crisis in the Far East
has affected earnings in a number of areas, our overall economy is sound.

     Despite  the  run-up in  stocks,  not every  company  is  selling at record
prices. We're still in a market of individual  businesses,  and there are plenty
of attractive opportunities that have not been fully recognized. Over the years,
we've been able to blend new technology  and resources in investment  strategies
that employ equity and credit research to find these opportunities.  Our aim, as
always, is to help investors reach their financial goals.

     Finally,  we hope you like the new  design of this  report.  Our annual and
semiannual  reports  contain  a wealth of  information  on fund  strategies  and
holdings.  The new design is intended to make this  information  more accessible
and should encourage you to take a closer look.

     We appreciate your investment with American Century.

Sincerely,

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

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

MARKET PERSPECTIVE

o    After one of the best three-year  runs on record in 1995-1997,  the S&P 500
     barely  paused to catch its breath  during  the six  months  ended June 30,
     gaining 17.66%.

o    Bonds  performed  well  too.  Low  inflation  and  falling  interest  rates
     translated into rising prices in most fixed-income markets.

o    Both stocks and bonds owe much of their  success to a robust  economy  with
     minimal inflation.

o    The success of financial  assets is also tied to the success of  individual
     companies.  Earnings growth has been annualizing at a double-digit rate for
     five of the last six years.

o    However, by some traditional measures, stock prices are very expensive. For
     example,  the  average  stock in the S&P 500 costs  roughly  25 times  last
     year's earnings, a historical high.

o    Our stock and bond markets remain resilient.  But investor expectations are
     running high, which is reflected in the S&P 500's steep climb over the last
     three and a half years.

MANAGEMENT Q&A

o    VP Advantage  gained 10.44%,  outperforming  its blended  benchmark  index,
     which  gained  8.95%.  The blended  index  combines the S&P 500, the Lehman
     Brothers  Intermediate  Government Bond Index,  and a three-month  Treasury
     bill index in proportion to the asset mix of VP Advantage's portfolio.

o    The  stock  portfolio  made  a  significant  contribution  to  performance.
     Standing  alone,  VP  Advantage's  stock  component was up 23.06%,  handily
     beating the S& P 500's return of 17.66%.

o    Several  pharmaceutical  positions  were  reduced.  Assets  were  moved  to
     financial services, insurance,  telecommunications,  broadcasting,  retail,
     media and cable companies.

o    American   Express  and  SunAmerica  were  among  the  portfolio's   strong
     performers.  Tele-Communications,  Inc.  and  Viacom,  two  cable and media
     positions, also did well.

o    The energy  services  industry was weak, and Cendant Corp., a marketing and
     franchising business,  dropped significantly after it discovered accounting
     irregularities at one of its major business units.

o    Though  financial  conditions  were  favorable,  bond  returns  were modest
     compared  with those  enjoyed  by  stocks.  VP  Balanced's  bond  portfolio
     returned 2.60%, similar to intermediate-term  U.S. bond returns in general.
     The cash position returned 2.13%.

o    Some  attractively  priced  mortgage-backed  securities  were  added to the
     portfolio.  The  higher  yields of the  mortgage-backeds  also  helped  the
     portfolio's  yield, but didn't hurt the average credit rating--it  remained
     AAA because the mortgage-backeds also carried a AAA rating.

[left margin]

THE  SUCCESS  OF  FINANCIAL  ASSETS IS ALSO TIED TO THE  SUCCESS  OF  INDIVIDUAL
COMPANIES.  EARNINGS  HAVE BEEN GROWING AT A  DOUBLE-DIGIT  RATE FOR FIVE OF THE
LAST SIX YEARS.

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

[photo of Mark Mallon]
Mark Mallon, senior vice president and managing director of American Century
Investments

A POWERFUL UPSLOPE IN STOCKS

     Just how quickly has the stock market  appreciated over the past few years?
It took  approximately 16 years,  from 1970-1985,  for the Standard & Poor's 500
Index to double.  Only six years later,  it had doubled again,  and roughly five
years after that,  in early 1997, it had doubled once more, to 800. As the chart
on page 4  illustrates,  the S&P 500's recent climb has been very steep.  At the
end of June 1998, the index was over 1100.

     Looked at another way, calendar 1995-1997 marked one of the best three-year
performance  runs on record.  It was, in fact, the most  consistent  performance
ever for  large-stock  indices  such as the S&P 500. All three years saw returns
top 20%. During the six months ended June 30, the S&P 500 barely paused to catch
its breath, gaining 17.66%.

     Lower  corporate  earnings,  a tight U.S.  labor  market,  and the  ongoing
economic  crisis in Asia caused only minor pullbacks in late 1997 and the second
quarter of 1998.

THE U.S. BOND MARKET

     Bonds have  performed  well too. Low inflation and falling  interest  rates
have translated into rising prices in most fixed-income markets. Between January
1 and June 30, 1998, the benchmark  30-year  Treasury bond yield fell from 5.93%
to 5.63%.  The 10-year  Treasury note yield,  a benchmark for  intermediate-term
bonds,  dropped from 5.75% to 5.45%.  When yields decline,  bond prices normally
increase.  The Lehman Brothers  Intermediate  Government Bond Index, a benchmark
for intermediate-term U.S. government securities returned 3.39%.

     Bonds  continued  to perform  relatively  well  despite  short-term  market
factors that held back sectors such as corporate and mortgage-backed securities.
Falling  interest rates  triggered a wave of mortgage  refinancing,  which had a
negative effect on mortgage-backed securities. When mortgages are refinanced, it
shortens the life of mortgage-backeds  and forces investors to reinvest at lower
yields.  The Asian crisis  affected the  performance of corporate  bonds because
investors  questioned the financial  health of companies that do business in the
Far East.

A POWERHOUSE ECONOMY

     Both stocks and bonds owe much of their  success to a robust  economy  with
minimal  inflation.  The U.S.  economy  is  currently  demonstrating  a vigor we
haven't seen in a generation.

o    Economic growth hit 3.8% in 1997, and 5.5% in the first quarter of 1998.

o    Inflation was a mere 1.4% for the 12 months ended June 30.

o    In 1997, prices rose at the slowest pace in 12 years.

o    Interest rates are among the lowest since the 1960s.

o    Unemployment was the lowest in 28 years.

o    The U.S. government is projecting the first budget surplus in 30 years.

Market Perspective (continued)
- --------------------------------------------------------------------------------

     The budget surplus means the  government's  borrowing  needs will shrink if
spending doesn't  increase.  The U.S. Treasury has already reduced the amount of
securities  it will issue.  The lower supply of Treasurys  should boost  prices.
Investors  may also  buy more  bonds in  other  sectors  of the U.S.  market  as
Treasurys become scarcer. At the same time, demand should remain strong.  Global
investors  often  turn to U.S.  bonds as a safe haven in times of  political  or
financial unrest.

CORPORATE AMERICA IS HEALTHY

     The success of financial  assets is also tied to the success of  individual
companies.  Earnings  have been growing at a  double-digit  rate for five of the
last six years. We are among the most technologically  proficient and productive
industrial nations, and as a result, U.S. companies are enjoying extraordinarily
high  investment  returns.   Given  the  positive  business  climate,  it's  not
surprising financial assets remain popular investments,  and that cash continues
to flow into the stock market at record volumes.

     However,  by some  traditional  measures,  stock prices are expensive.  The
average  stock in the S&P 500 costs  roughly 25 times last  year's  earnings,  a
historical high.  Corporate assets are also richly valued.  Investors are paying
roughly five times balance sheet assets,  or twice the historical  average.  The
dividend  yield on the  average  S&P 500 stock has fallen  below  1.5%,  another
record.

EARNINGS, INFLATION, AND  INTEREST RATES

     What could  derail  the  financial  markets?  Most  probably,  an upturn in
inflation or a substantial decline in earnings. Late last year, the spike in oil
prices,  combined with the deepening Asian crisis, briefly raised the specter of
higher inflation and lower earnings.  Stocks reacted negatively.  They also fell
back in the second quarter of 1998,  when it appeared the Asian  recession would
cut deep into corporate earnings in the U.S.

     Should  inflation  pick up,  interest  rates are likely to rise too, as the
Federal Reserve adjusts rates upward to slow the economy.  Higher interest rates
increase the cost of borrowing for everyone,  from  corporations  to prospective
home buyers, and thus tend to slow economic growth and dampen inflation.

     In 1997, inflation failed to take off. Oil prices went into a tailspin when
Asian  demand  fell.  In early 1998,  as crude oil prices hit a  nine-year  low,
interest  rates  declined and stocks  soared,  even though the fallout from Asia
threatened to slow both corporate earnings and U.S. economic growth.

     Our stock and bond markets remain resilient.  Their long-term prospects are
still favorable.  But investor expectations are running high, which is reflected
in the S&P 500's  steep  climb  over the last  three and a half  years.  In this
environment, financial markets could prove vulnerable to disappointments.

VP Balanced--Q&A
- --------------------------------------------------------------------------------

     An interview  with  portfolio  managers Jim Stowers III, Bruce Wimberly and
John  Sykora  of our  equity  staff,  and Bud  Hoops  and  Jeff  Houston  of our
fixed-income group. They all help oversee the VP Advantage Fund.

WHAT WERE VP  ADVANTAGE'S  RETURNS  FOR THE FIRST HALF OF ITS FISCAL  YEAR ENDED
JUNE 30, 1998?

     VP Advantage  gained 10.44%,  outperforming  its blended  benchmark  index,
which gained 8.95% for the same six months.  The blended index  combines the S&P
500 (40%), the Lehman Brothers  Intermediate  Government Bond Index (40%), and a
three-month  Treasury bill index (20%).  This is the same mix as VP  Advantage's
target protfolio of stocks, bonds and cash.

     The  bond  and  cash  components  are  intended  to lend  the  portfolio  a
conservative  flavor. The aim is to generate  respectable returns in up markets,
and provide a stabilizing influence should the stock market become volatile.

CAN YOU IDENTIFY THE PRIMARY REASONS VP ADVANTAGE OUTPERFORMED ITS BENCHMARK?

     The stock  portfolio made a significant  contribution.  Standing  alone, VP
Advantage's  stock  component was up 23.06% in the first half. That handily beat
the S&P 500's return of 17.66%. We used American Century's proprietary database,
pricing  screens,  and financial  analysis to find companies and industries with
accelerating revenues and earnings. From this broad menu, we selected individual
businesses  whose revenue and earnings growth looked to be clearly  sustainable.
We also paid close attention to earnings visibility:  in other words, we focused
additional  emphasis on companies with  recurring  revenue  streams.  We believe
these  companies  have a higher  probability  of  meeting  or  beating  earnings
estimates.

WHY THE EMPHASIS ON VISIBILITY?

     Today  the  earnings  picture  remains  somewhat  clouded  because  overall
earnings  growth slowed in 1997 and in the first quarter of 1998. Many companies
that used to hit earnings  targets  regularly  are now missing  their marks.  We
believe there is still a level of optimism built into earnings estimates for the
second half of the year. Those projections are likely to come down. The economic
turmoil in Southeast Asia is hurting  profits and revenues in many groups,  such
as technology and energy, as are wage pressures in the U.S. The strong dollar is
also making U.S. merchandise less competitive  overseas.  Foreign buyers have to
pay for our products in their local  currencies,  which become less  valuable as
the dollar rises.

THAT SOUNDS LIKE THE BAD NEWS. WHAT'S THE GOOD NEWS?

     The good news is the U.S. economy. It remains healthy. As always, there are
areas of opportunity.  From our point of view, even the earnings slowdown has an
upside: it creates an environment in which effective stockpicking can really add
value.  We believe  that's one of the reasons VP Advantage  generated  such good
results during the first six months of 1998. Our emphasis on earnings visibility
has worked.

DID THE SEARCH FOR EARNINGS VISIBILITY  TRIGGER CHANGES IN THE PORTFOLIO?

     Yes. We reduced several pharmaceutical positions where the earnings picture
was   fading.    Assets    migrated   to    financial    services,    insurance,
telecommunications,   broadcasting,   retail,  media  and  cable  companies.  In
financial services we hold

VP Advantage--Q&A (continued)
- --------------------------------------------------------------------------------

American   Express   and   SunAmerica.   Media  and  cable   companies   include
Tele-Communications,  Inc.  (TCI) and Viacom.  Both TCI and Viacom are improving
their balance sheets and generating strong cash flow growth.

     We also have high expectations for our retailers. Earnings growth led us to
the  value-conscious  merchandisers--Wal-Mart,  Costco and Dayton Hudson,  which
owns Target  Stores.  We continue to think these  companies  have sound business
models for sustained growth.

WHAT ABOUT SOME OF THE OTHER ATTRACTIVE GROWTH OPPORTUNITIES YOU JUST MENTIONED

     We're excited about  telecommunications  and the internet  phenomenon.  The
internet  is bigger  today  than many  people  ever  thought it would be, and we
believe it will  continue  to outpace  expectations.  Companies  such as America
Online (AOL) and WorldCom on the network side and Cisco Systems on the equipment
side have emerged as dominant  providers.  We expect  their market  positions to
improve. AOL, for example, has great earnings visibility. The company collects a
monthly fee from an expanding pool of subscribers. Earlier this year it was able
to raise  prices--something  that has become  fairly rare in our low-  inflation
economy.  WorldCom  is  the  leader  in  providing  commercial  voice  and  data
transmission  internationally.  Its  fiberoptic  network  is  far  ahead  of the
competition  in  an  environment  where  voice  and  data  traffic  should  grow
substantially as international commerce becomes increasingly sophisticated.

HOW DID VP ADVANTAGE'S LARGER POSITIONS PERFORM?

     Many  of  our  largest  holdings  were  among  the  best  performers.  Tyco
International,    Clear   Channel   Communications,    American   Express,   and
Tele-Communications,  Inc.  all added  significantly  to  results.  Our  largest
position,  General Electric (GE), was also up  substantially.  GE's earnings per
share  increased by 14% in the first quarter of 1998. The company is pursuing an
aggressive  share-buyback  program  and  has  expanded  its  medical  diagnostic
equipment business by purchasing  Diasonics,  a leading ultrasound imaging firm.
GE is also  shopping for assets in Asia,  where  prices are severely  depressed.
Finally, we took profits in Coca-Cola and drug manufacturer  Pfizer,  which were
among our top ten holdings last year.

WERE THERE ANY DISAPPOINTMENTS OVER THE SIX MONTHS?

     There are always some  underachievers.  The energy  services  industry  was
weak,  and  Cendant  Corp.,  a  marketing  and  franchising  business,   dropped
significantly after it discovered accounting  irregularities at one of its major
business  units.  Cendant  owns such  brand  names as  Ramada,  Howard  Johnson,
Coldwell Banker, Century 21 and Avis.

LET'S TURN TO THE BOND PORTFOLIO. HOW DID IT PERFORM?

     Though  financial  conditions  were  favorable,  bond  returns  were modest
compared with those enjoyed by stocks.  VP Advantage's  bond portfolio  returned
2.60%, similar to intermediate-term U.S. government bond returns in general. The
cash position returned 2.13%.

HOW WAS THE BOND PORTFOLIO POSITIONED?

     As a rule, we take a  conservative,  no-frills  approach to complement  the
stock  portfolio  and generate the best possible  risk-adjusted  returns for the
fund as a whole.  We invest  primarily in  intermediate-term  Treasury bonds, we
hold only  securities  rated AAA for credit  quality,  and we usually don't make
large

VP ADVANTAGE--Q&A (CONTINUED)
- --------------------------------------------------------------------------------

interest rate bets. We consider the fund's duration  target to be  approximately
four years, and we usually don't stray too far from that position. Duration is a
measure of the portfolio's  sensitivity to interest rate changes--the higher the
duration,  the more the portfolio's value will fluctuate in response to interest
rate movements.

     During  the  first  half  of  the  year,  we  added  some   mortgage-backed
securities,  which seemed attractively  priced. A wave of mortgage  refinancings
after interest rates fell sharply in the fourth quarter of 1997 caused the value
of mortgage-backed  securities to decline (and yields to rise) relative to other
bond  sectors.  The  higher  yields  of the  mortgage-backeds  also  helped  the
portfolio's yield, but the securities didn't hurt the portfolio's average credit
rating,  which  remained  AAA because the  mortgage-backeds  also  carried a AAA
rating.

     Given the  possibility  of weaker  economic  conditions  and lower interest
rates, we also increased the portfolio's  sensitivity to interest rate changes a
bit, raising the weighted average maturity and duration from where they had been
six months earlier.

WHAT IS YOUR OUTLOOK FOR BONDS AS WE HEAD INTO THE SECOND HALF OF THE YEAR?

     We're optimistic,  but not completely bullish. What tempers our bullishness
is the underlying  strength of the U.S.  economy,  which might ignite inflation.
Low  unemployment  and high consumer  confidence are forces that could help fend
off any weakness from the economic  recession in Asia. Because of the offsetting
forces of overseas  weakness and domestic  strength,  U.S.  interest  rates have
fluctuated in a relatively  narrow range (with a downward  bias) so far in 1998,
and we expect that to continue.

     Supply and demand fundamentals are still favorable.  The federal government
is running its first budget  surplus in 30 years,  which  reduces  Treasury bond
supply and exerts more downward pressure on interest rates.

LOOKING  AHEAD,  WHAT ARE YOUR  STRATEGIES  FOR VP  ADVANTAGE'S  STOCK  AND BOND
PORTFOLIOS?

     On the fixed-income  side, we've steered a pretty steady course,  and we'll
continue to do so. If Treasurys rally strongly, we could look to add some better
values and higher yields from  mortgage-backed and government agency securities,
if  such  opportunities  are  available.  As for  the  equity  component  of the
portfolio,  we will remain  focused on  attractive  opportunities  among larger,
high-quality  companies.  Management  is  also  exploring  ways to  enhance  the
efficiency  of the fund.  Any changes  should  continue to produce a diversified
portfolio  that has the  potential  for  long-term  capital  growth and  current
income.

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.  The net assets  divided by the number of
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
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  breakout  tells  you the  value  of net  assets  that  are
performance-related,  such as income and  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, 1998 (UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION  --  American   Century   Variable   Portfolios,   Inc.,  (the
Corporation)  is  registered  under  the  Investment  Company  Act of 1940 as an
open-end  diversified   management  investment  company.   American  Century  VP
Advantage  (the  Fund)  is  one  of  the  six  series  of  funds  issued  by the
Corporation.  The Fund's  investment  objective  is current  income and  capital
growth.  The  Fund  seeks to  achieve  its  investment  objective  by  investing
approximately 20% of the Fund's assets in cash or cash equivalents, 40% in fixed
income securities with a weighted average maturity of three to ten years and 40%
in   equity   securities   that   are   considered   by   management   to   have
better-than-average  prospects  for  appreciation.   The  following  significant
accounting  policies,  related to the Fund,  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 Fund 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 investments  are a component of realized
gain  (loss)  on  investments  and  unrealized  appreciation  (depreciation)  on
investments, respectively.

     FORWARD  FOREIGN  CURRENCY  EXCHANGE  CONTRACTS  -- The Fund 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 Fund's  exposure  to  foreign  currency  exchange  rate  fluctuations.  When
required,  the Fund will segregate  assets in an amount  sufficient to cover its
obligations  under the hedge  contracts.  The net U.S.  dollar  value of foreign
currency  underlying  all  contractual  commitments  held  by the  Fund  and the
resulting  unrealized  appreciation or depreciation  are determined  daily using
prevailing exchange rates.  Forward contracts involve elements of risk in excess
of the amount  reflected in the  Statement of Assets and  Liabilities.  The Fund
bears 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.  There were no open
forward foreign currency exchange contracts at June 30, 1998.

     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 equal to or 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 trans-

JUNE 30, 1998 (UNAUDITED)

fer 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 Fund to distribute all taxable
income and 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  and 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.  These estimates and assumptions  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 a Management  Agreement with ACIM,  that
provides the Fund with investment  advisory and management  services in exchange
for a single, unified fee. The Agreement provides that all expenses of the Fund,
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 the Fund's  average
daily closing net assets during the previous  month.  The annual  management fee
for the Fund is 1.00%.

     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.

BACKGROUND INFORMATION
- --------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY AND POLICIES

     VP Advantage's investment philosophy focuses on four important principles.

     We attempt to keep the fund's equity and bond portfolios  fully invested at
their  respective  percentages  (see below),  regardless  of  short-term  market
activity.  Experience  has shown that  market  gains can occur in  unpredictable
spurts and that missing even some of those opportunities may significantly limit
potential for gain.

     For  the  equity  portfolio,  the  management  team  seeks  to  own  highly
successful  companies,  which we define as those whose earnings and revenues are
growing at accelerating rates.

     For the fixed-income portfolio, "quality first" is the rule. The management
team seeks only investment-grade bonds and money market  securities--those rated
in  the  top  four  quality  categories  by  nationally  recognized  statistical
organizations.

     Each portfolio is managed by a team, rather than by one "star" manager.  We
believe this allows us to make better, more consistent management decisions.

     VP ADVANTAGE  seeks to provide  current  income and capital  growth.  Under
normal  market  conditions  the fund keeps  about 40% of its assets in  quality,
intermediate-term  U.S. bonds, 20% in U.S.  government  money market  securities
with a weighted  average maturity of six months or less and the remaining 40% in
the  stocks of firms  considered  by  management  to have  better  than  average
prospects for appreciation.



COMPARATIVE INDICES

     The indices  listed  below are used in the report to serve as a  comparison
for the performance of the fund. They are not investment  products available for
purchase.

     The BLENDED INDEX is considered the benchmark for VP Advantage. It combines
three  widely  known  indices  in  proportion  to the  asset  mix  of the  fund.
Accordingly,    40%   of   the   index   is    represented    by   the    Lehman
Intermediate-Government  Bond Index.  Another 40% of the index is represented by
the S&P 500 and the remaining 20% of the index is  represented  by a three-month
Treasury bill index.

     The LEHMAN  INTERMEDIATE  GOVERNMENT  BOND INDEX is considered to represent
the performance of a high-quality  portfolio of intermediate-term  U.S. Treasury
and government agency bonds. The index is composed of over 800 U.S. Treasury and
government agency securities with an average maturity of three to five years.

     The  S&P  500  is a  capitalization-weighted  index  of the  stocks  of 500
publicly-traded  U.S.  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 performance.

     The 90-DAY  TREASURY BILL INDEX is derived from secondary  market  interest
rates as published by the Federal Reserve Bank.

GLOSSARY
- --------------------------------------------------------------------------------

FIXED-INCOME TERMS

o CREDIT QUALITY  reflects the financial  strength of a debt security issuer and
the likelihood of timely payment of interest and principal.

o DURATION  is a measure  of the  sensitivity  of a  fixed-income  portfolio  to
changes in interest rates. As the duration of a portfolio increases,  the impact
of a change in interest rates on the value of the portfolio also increases.

o STANDARD & POOR'S (S&P) is an independent rating company,  one of the two best
known in the U.S. (the other is Moody's).  The credit  ratings issued by S&P and
Moody's  reflect  the  perceived  financial  strength  (credit  quality) of debt
issuers.  Debt securities rated "investment  grade" (deemed to be of high enough
credit quality to be appropriate  investments for banks and other  institutions)
by S&P are those rated BBB or higher (the highest rating is AAA).

o WEIGHTED AVERAGE MATURITY (WAM),  another  measurement of the sensitivity of a
fixed-income  portfolio to interest  rate  changes,  indicates  the average time
until the  principal  in the  portfolio  is expected  to be repaid,  weighted by
dollar amount.  The longer the WAM, the more interest rate exposure and interest
rate sensitivity the portfolio has.

RETURNS

o TOTAL  RETURN  figures  show the overall  percentage  change in the value of a
hypothetical  investment  in  the  fund  and  assume  that  all  of  the  fund's
distributions are reinvested.

o AVERAGE ANNUAL RETURNS  illustrate the annually  compounded returns that would
have produced the fund's cumulative total returns if the fund's  performance had
been  constant  over the  entire  period.  Average  annual  returns  smooth  out
variations in a fund's return;  they are not the same as  year-by-year  results.
For year-by-year  total returns,  please refer to the "Financial  Highlights" on
page 16.

EQUITY TERMS

o  BLUE-CHIP  STOCKS  --  generally  considered  to be the  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.

o 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.

o GROWTH STOCKS -- generally  considered to be the 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, computer hardware and computer software companies.

o  LARGE-CAPITALIZATION  ("LARGE-CAP")  STOCKS -- generally considered to be the
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,  the S&P 500 and the  Russell  1000
Index.

o  MEDIUM-CAPITALIZATION  ("MID-CAP")  STOCKS -- generally  considered to be the
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.

o 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.)

o  SMALL-CAPITALIZATION  ("SMALL-CAP")  STOCKS -- generally considered to be the
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 Nasdaq Composite Index and the Russell 2000 Index.

o 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.

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 turn,  will make us successful.  That is the principle that

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 report  actually costs slightly less than the old ones. They 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.

     Stocks have posted historic  returns over the last few years. The first six
months of 1998  continued  this  momentum,  despite  some  slowing in the second
quarter due to the economic and financial  crisis in Asia.  Large companies once
again  outpaced  smaller ones.  The generous  market  values  accorded many very
large,  high-profile companies grew even more generous,  while midsize and small
stocks turned in respectable  results.  Growth stocks continued to outpace value
stocks.

     We've  been  optimistic  about  the stock  market  for many  years,  and we
continue  to believe  stocks  should  produce  fine  results  over the long run.
Corporate  America  is in good  health.  Many  companies  have  cleaned up their
balance sheets, are highly productive,  and are generating impressive returns on
products and investments. While the crisis in Asia has affected earnings in some
areas, the overall U.S. economy is sound.

     Despite the general run-up in stocks, however, not every company is selling
at  record  prices.  We are  still in a market  of  individual  businesses,  and
investors'  treatment of these  companies  can often be affected by sentiment as
well  as  by   facts.   As  a   result,   there   are   plenty   of   attractive
opportunities--companies  whose  earnings  growth or value  have not been  fully
recognized, or have been temporarily discounted.

     The ability of the quantitative equity team that manages VP Income & Growth
to find  these  opportunities  is  clearly  reflected  in the  fund's  excellent
performance during the first half of the year. Even though the fund is less than
a year old, the team's approach adheres to investment  strategies and techniques
that American  Century  developed over the last eight years.  We've been able to
blend  experienced  management  with new technology and resources,  all aimed at
helping investors reach their financial goals.

     We  understand  that it's  important  for you to track the progress of your
fund and follow the strategies of the investment team. For that reason,  we hope
you like the new  expanded  format  and  design of this  report.  Our annual and
semiannual  reports  contain  a wealth of  information  on fund  strategies  and
holdings.  We've  expanded  the  report  to give  you  more  of  this  important
information,  and the new  design  is  intended  to make this  information  more
accessible and easier for you to read.

     We appreciate your investment with American Century.

Sincerely,

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

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

MARKET PERSPECTIVE

*   The S&P 500's recent climb has been very steep.  Calendar  1995-1997  marked
    one of the best three-year performance runs on record for the index.

*   The sharp ascent  continued during the first six months of 1998. The S&P 500
    gained 17.7%.

*   The stocks of large companies  continued to outperform  those of midsize and
    small companies.

*   Market leadership has been narrow;  the returns of the 100 biggest companies
    in the S&P 500 outdistanced the remaining 400.

*   Stocks owe much of their success to a robust economy with minimal inflation.
    The U.S. economy is demonstrating a vigor we haven't seen in a generation.

*   Many U.S. companies are enjoying extraordinarily high profitability. The
    positive business climate is encouraging money to flow into the stock
    market in record volumes.

*   By some traditional measures, stock prices are expensive. Earnings multiples
    have hit  historical  highs,  and dividend  yields have fallen to historical
    lows.

*   An upturn in inflation or a substantial  decline in corporate earnings could
    derail the financial  markets.  Investor  expectations  are running high. In
    this environment, stocks could prove vulnerable to disappointments.

MANAGEMENT Q&A

*   VP  Income  & Growth  posted  exceptional  gains  compared  with  historical
    averages for the stock market.

*   The fund's 17.47% return was notably  higher than the 10.64%  average return
    of its peers, according to Lipper Analytical Services. (See Total Returns on
    page 5.)

*   VP Income & Growth benefited from its  concentration in S&P 500 stocks,  our
    quantitative  approach to managing the portfolio and our policy of remaining
    fully invested in stocks.

*   The portfolio's  underweighting in several blue-chip  consumer  non-cyclical
    growth stocks, which seemed overpriced to our quantitative models,  dampened
    returns slightly.

*   Banking,  communications  services and  financial  services were some of the
    better-performing industries that our models favored.

*   Despite some interim  volatility,  stock  returns for the first half of 1998
    were well above historical norms.

*   We will probably  maintain the portfolio's  slightly  defensive stance going
    forward.

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

[photo of Mark Mallon]
Mark Mallon,  senior vice  president and managing  director of American  Century
Investments.

A POWERFUL UPSLOPE

     Just how quickly has the stock market  appreciated over the past few years?
It took  approximately 16 years,  from 1970-1985,  for the Standard & Poor's 500
Index to double.  Only six years later,  it had doubled again,  and roughly five
years  after  that,  in early 1997,  it had  doubled  once more,  to 800. As the
accompanying chart illustrates, the S&P 500's recent climb has been very steep.
At the end of June 1998, the index was just over 1,100.

     Looked at another way, calendar 1995-1997 marked one of the best three-year
performance  runs on record.  It was, in fact, the most  consistent  performance
ever for large-stock indices such as the S&P 500. All three years saw returns of
more than 20%. During the first half of 1998, the S&P 500 barely paused to catch
its breath,  gaining 17.7%. Lower corporate earnings, a tight U.S. labor market,
and the  ongoing  economic  crisis in Asia caused  only minor  pullbacks  in the
second quarter of 1998.

A POWERHOUSE ECONOMY

     Stocks  owe  much  of  their  success  to a  robust  economy  with  minimal
inflation.  The U.S. economy is currently  demonstrating a vigor we haven't seen
in a generation:

*   U.S.  economic  growth  hit 3.9% in 1997,  and 5.5% in the first  quarter of
    1998.

*   Inflation was a mere 1.7% for the year ended June 30.

*   In 1997, prices rose at the slowest pace in 12 years.

*   Nominal interest rates are among the lowest since the 1960s.

*   Unemployment in 1997 was the lowest in 28 years.

*   The U.S. government is projecting the first budget surplus in 30 years.

     A successful  market is also tied to the success of  individual  companies.
Earnings growth and productivity  are at the top of the business agenda.  We are
among the most  technologically  proficient of the industrial nations,  and as a
result, U.S. companies are enjoying  extraordinarily high profitability.  A wave
of mergers,  involving such high-profile  names as Travelers Group and Citicorp,
has, in general, increased efficiency and boosted profits.

     In 1997 and the first quarter of 1998,  earnings  growth  slowed,  but only
after a  double-digit  growth  spurt that lasted five years.  Given the positive
business climate,  it's not surprising  stocks remain such a popular  investment
and that cash continues to flow into the market at record volumes.

     However,  by some  traditional  measures,  stock prices are expensive.  The
average stock in the S&P 500 now costs more than 25 times last year's  earnings,
a historical high. Corporate assets are

also richly  valued.  Investors  are paying  roughly  five times  balance  sheet
assets, or twice the historical  average.  The dividend yield on the average S&P
stock has fallen to less than 1.5%, another record.

BIG WAS BETTER, GROWTH WAS IN

     The stocks of large  companies (as reflected in the S&P 500) have continued
to  outperform  those of midsize and small  companies in the first half of 1998.
Leadership  has been  narrow.  The  largest  100 stocks in the S&P,  measured by
market value,  have  outdistanced  the remaining 400. And the very  largest--GE,
Coca-Cola,  Microsoft, and other household names--have posted the biggest gains.
These high-profile  stocks are in vogue because they are liquid--that is, easier
to trade in large quantities. In theory, their liquidity should make them easier
to exit if the stock market slips.

     The fascination  with growth and size has been prevalent for several years.
It was also in vogue a  generation  ago,  in the early  1970s,  when the  "Nifty
Fifty"  (companies  that were also  household  names)  provided the  performance
fireworks.

EARNINGS, INFLATION AND INTEREST RATES

     What could  derail  the  financial  markets?  An upturn in  inflation  or a
substantial  decline in earnings  probably could. You don't have to look farther
than the second  quarter,  when the Asian  crisis  threatened  earnings  and the
Federal Reserve hinted a rate hike was possible.  In late 1997, the spike in oil
prices,  combined  with the deepening  Asian crisis,  also raised the specter of
higher inflation and lower earnings, and stocks fell back.

     If inflation  picks up,  interest  rates are likely to rise, as the Federal
Reserve tries to head off inflation by pushing  rates  higher.  Higher  interest
rates  increase  the  cost of  borrowing  for  everyone,  from  corporations  to
prospective  home  buyers,  and thus tend to slow  economic  growth  and  dampen
inflation.

     In 1997, inflation failed to take off. Oil prices went into a tailspin when
Asian  demand  fell.  In early 1998,  as crude oil prices hit a  nine-year  low,
interest  rates  declined  and stocks  soared even though the fallout  from Asia
still threatened to slow both corporate earnings and U.S. economic growth.

     This is a very  resilient  market.  We believe its long-term  prospects are
still  substantial.  But  investor  expectations  are  running  high,  which  is
reflected in the S&P 500's steep climb over the last three and a half years.  In
this environment, stocks could prove vulnerable to disappointments.

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

     An interview with John Schniedwind and Kurt Borgwardt,  portfolio  managers
on the VP Income & Growth fund investment team.

HOW DID THE FUND PERFORM FOR THE SIX MONTHS ENDED JUNE 30, 1998?

     VP  Income & Growth  posted  exceptional  gains  compared  with  historical
averages for the stock market.  The fund's 17.47% return was notably higher than
the 10.64%  average  return of the 35 "Variable  Annuity  Equity  Income  Funds"
tracked by Lipper Analytical Services. The fund's return was comparable with the
17.66% return of its benchmark, the S&P 500. (See the Total Returns table on the
previous page for other fund performance comparisons.)

WHAT HELPED THE FUND PERFORM SO WELL?

     VP Income & Growth benefited from its concentration in S&P 500 stocks,  our
quantitative  approach to managing  the  portfolio  and our policy of  remaining
fully invested in stocks.

     The   fund's   portfolio   is   comprised   predominately   of   shares  of
large-capitalization  (large-cap)  issues, such as the ones in the S&P 500, that
represent  some of the biggest  corporations  in the U.S.  The  relatively  more
consistent   earnings  that  these  stocks  have   traditionally   offered  over
small-capitalization (small-cap) issues made large-cap stocks more attractive to
investors.  That favoritism was driven by uncertainty over economic  problems in
Asia  and  concern  that  the  turmoil  would  dampen  U.S.  corporate  profits,
particularly for smaller,  less-diversified  companies.  Substantial money flows
into mutual funds,  often put to work in highly liquid  large-cap  stocks,  also
drove prices higher.

     Our  quantitative  approach to managing the portfolio also boosted returns.
VP Income & Growth's computer models favored shares of banks, as well as several
other stocks,  that performed very well. Our policy of remaining  fully invested
in U.S.  stocks was  another  return-enhancing  element--keeping  the fund fully
invested during this bull market helped maximize returns.

WHAT FACTORS DETRACTED FROM THE FUND'S PERFORMANCE?

     The portfolio's  underweighting in several blue-chip consumer growth stocks
such as Coca-Cola,  General  Electric and  Gillette,  compared with the S&P 500,
detracted  slightly.  One of the many factors our models take into consideration
is a  stock's  value--whether  it  appears  underpriced  based on the  company's
earnings growth, business fundamentals or intrinsic value. It was this component
of the models  that led us to avoid most of these types of stocks that drove the
market in 1996 and 1997.  Despite  what we believed  were  inflated  valuations,
these stocks performed surprisingly well.

YOU MENTIONED THAT YOUR MODELS FAVORED BANK STOCKS. CAN YOU TELL US ABOUT ONE OF
THESE STOCKS IN THE PORTFOLIO, HOW THE STOCK PERFORMED AND WHY IT WAS CHOSEN?

     Chase Manhattan is a good example.  For the first six months of 1998, Chase
shares  returned  39%,  compared  with a 10%  return for the first six months of
1997.  The company's  strong revenue and earnings  growth,  and the low interest
rate environment made the stock attractive to our models. Chase's relatively low
price compared with similar stocks was also attractive to our models.

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

WHAT OTHER INDUSTRIES DID YOUR MODELS FAVOR?

     Communications services,  utilities and financial services were some of the
other  industries our models  favored.  Expanding their services to benefit from
The Federal  Communications  Act of 1996,  telecommunications  companies such as
Ameritech and US WEST Communications provided growth potential.

     Select utility companies that positioned themselves to benefit from partial
industry  deregulation looked attractive,  too. The electric utility stocks also
provided  relatively  high  yields,   helping  the  portfolio  meet  its  income
objective.

     Financial services stocks like Travelers Group were also attractive because
they  benefited  from low  inflation  and  interest  rates  as well as  industry
consolidation.

SPEAKING OF INDUSTRY  CONSOLIDATION,  SEVERAL LARGE MERGERS WERE  ANNOUNCED OVER
THE LAST SIX MONTHS. HOW DO MERGERS AFFECT VP INCOME & GROWTH'S PERFORMANCE?

     That  depends  on how  the  portfolio  is  positioned  with  regard  to the
companies involved.  If the portfolio is invested in the company to be acquired,
returns are often enhanced.  That's because the acquiring company usually pays a
premium  to  purchase  the  outstanding  shares  of the  company  being  bought.
Speculative  investors  often bid up shares of the  company  to be  acquired  in
anticipation of a purchase premium.

     If the portfolio is invested in the company  making the  acquisition,  then
returns can suffer if  investors  believe that too high a premium is being paid,
or if they  expect  future  earnings  to be  diluted.  This can  translate  into
short-term losses for the acquiring company, reducing the price of its shares.

     Generally speaking, merger announcements by high-profile companies can also
fuel speculation that further  industry  consolidation  lies ahead. As a result,
stocks of companies  in the industry as a whole often rise as investors  eagerly
bid up shares in anticipation of further activity.  The rise in the stock prices
of many  Internet  browsing  companies  this  year is a good  example  of such a
situation.

     So, even if the  portfolio  does not directly  hold stocks of either of the
merging  companies,  there  can  still  be an  indirect  effect  on  the  fund's
performance.

ARE  THERE  PENDING   MERGERS  THAT  MIGHT  DIRECTLY   AFFECT  THE   PORTFOLIO'S
PERFORMANCE?

     Yes.  Many of the larger  pending  mergers are in the banking and financial
services industries, which were the portfolio's two largest industry holdings at
the end of June.  (See the Top Five  Industries  chart on page 8.) For instance,
one such  announcement was made by Travelers Group,  which intends to merge with
Citicorp.  Another  sizable  merger  in the  works is  between  NationsBank  and
BankAmerica.

     In the communications services industry,  there is a pending merger between
Ameritech and SBC  Communications.  Any of these mergers could affect the fund's
returns.

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

WHAT IS YOUR OUTLOOK FOR U.S. STOCKS FOR THE REST OF 1998?

     Despite some interim  volatility,  stock returns for the first half of 1998
were well above  historical  norms.  Unfortunately,  the odds are  against  such
returns continuing for the rest of the year. Profits posted by S&P 500 companies
have slowed this year  compared  with the same period last year.  Asian woes are
the main culprit behind the slowing  returns.  Until concrete plans are set into
action to alleviate  Asia's  financial and economic  crisis,  U.S.  corporations
deriving a large portion of their  profits from Asia could see  continued  share
price volatility.

     We are also concerned that high stock valuations  (especially  among larger
stocks)  could  increase  market  volatility  in the  months  ahead.  Shares  of
companies failing to meet or exceed investor expectations for profit growth were
pummeled in 1997,  and continue to be hammered in 1998.  Another  uncertainty is
whether the strong cash flows into stock mutual funds will continue.

     On a positive note, the U.S. economy  continues to expand with historically
low  inflation  and   unemployment.   Interest  rates  are  very  low,  allowing
corporations   to  borrow  funds  to  finance  new  projects  and  expand  their
businesses.

WHAT ARE YOUR PLANS FOR THE PORTFOLIO FOR THE NEXT SIX MONTHS?

     From a sector standpoint,  we will continue to use our quantitative  models
to identify  attractive  candidates  for  investment.  The low inflation and low
interest rate environment  provides a potentially ideal climate for many sectors
to continue  producing solid returns.  The portfolio's  underweighting  in large
consumer  non-cyclical  growth  stocks  will  likely  remain  in  place.  Though
performing  relatively well in recent times, we are concerned that the prices of
many of these stocks are unrealistically high.

     Staying fully invested in stocks will remain a priority.  This will enhance
returns if the market continues to rally. However, if the market declines, being
fully invested  could also dampen  returns.  To mitigate such a possibility,  we
will continue to look for shares of companies with improving  earnings forecasts
that appear to be undervalued.  This strategy will hopefully  provide  investors
with attractive returns and an acceptable level of risk.

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.  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
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  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.

JUNE 30, 1998 (UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION--American Century Variable Portfolios, Inc., (the Corporation)
is  registered  under  the  Investment  Company  Act  of  1940  as  an  open-end
diversified  management investment company.  American Century VP Income & Growth
(the  Fund) is one of the six  series of funds  issued by the  Corporation.  The
Fund's  investment  objective  is dividend  growth,  current  income and capital
appreciation  through  investment in common  stocks.  The following  significant
accounting  policies,  related to the Fund,  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.

     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.

     FOREIGN  CURRENCY  TRANSACTIONS--The  accounting  records  of the  Fund 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 investments  are a component of realized
gain  (loss)  on  investments  and  unrealized  appreciation  (depreciation)  on
investments, respectively.

     FORWARD  FOREIGN  CURRENCY  EXCHANGE  CONTRACTS--The  Fund 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 Fund's  exposure  to  foreign  currency  exchange  rate  fluctuations.  When
required,  the Fund will segregate  assets in an amount  sufficient to cover its
obligations  under the hedge  contracts.  The net U.S.  dollar  value of foreign
currency  underlying  all  contractual  commitments  held  by the  Fund  and the
resulting  unrealized  appreciation or depreciation  are determined  daily using
prevailing exchange rates.  Forward contracts involve elements of risk in excess
of the amount  reflected in the  Statement of Assets and  Liabilities.  The Fund
bears 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.  There were no open
forward foreign currency exchange contracts at June 30, 1998.

JUNE 30, 1998 (UNAUDITED)

     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
value of 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 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 or Agency obligations.

     INCOME TAX  STATUS--It is the policy of the Fund to distribute  all taxable
income and 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  and net
realized capital gains are expected to be 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 realized  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.  These estimates and assumptions  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--Fund's 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,  that
provides the Fund with investment  advisory and management  services in exchange
for a single, unified fee. The Agreement provides that all expenses of the Fund,
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 the Fund's  average
daily closing net assets during the previous  month.  The annual  management fee
for the Fund is 0.70%.

     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.

Background Information
- --------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY AND POLICIES

     American Century's quantitative equity funds are managed to provide returns
that are  representative  of the  U.S.  stock  market  as a  whole.  The  funds'
investment  management  team  employs  several  computer  models as key tools in
making investment decisions. A stock-ranking model analyzes more than 2,500 U.S.
stocks,  giving  each a score  based on growth and value  measures  such as cash
flow, earnings growth, and price/book ratio. Once the stocks are ranked, another
model helps create a portfolio that balances high-scoring stocks with an overall
risk level that is comparable to the broader stock market.

     VP  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 30% higher than the yield of the S&P
500.

COMPARATIVE INDICES

     The following index is used in the report for fund performance comparisons.
It is not an investment product available for purchase.

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

LIPPER RANKINGS

     LIPPER  ANALYTICAL  SERVICES,  INC. is an  independent  mutual fund ranking
service that groups funds according to their investment objectives.

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.

PORTFOLIO STATISTICS

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

* 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.

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  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.

* 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.

STATISTICAL TERMINOLOGY

* 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/BOOK  RATIO--  a stock  value  measurement  calculated  by  dividing  a
company's stock price by its book value per share,  with the result expressed as
a multiple  instead of as a  percentage.  (Book value per share is calculated by
subtracting a company's liabilities from its assets, then dividing that value by
the number of outstanding shares.)
