                            LETTER TO POLICYHOLDERS

July 20, 1999

Dear Policyholder,
    With the volatility that we've experienced recently in many financial
markets, some investors have sold securities because of uncertainty about where
the markets were going, only to be left rethinking whether they made the right
decision. We've witnessed this kind of market activity numerous times over the
past several years, sparked by concerns such as the impact of the Asian economic
crisis, high stock valuations, or, most recently, the stability of many high-
flying technology companies. While these fears eventually subsided, investors
who may have sold during this period were unable to reap the benefits of the
subsequent rally. That's partly because most of the recent big gains happened in
relatively short periods of time. This kind of volatility--and the danger of
making short-term decisions--highlights the importance of investing for the long
term, in accordance with your individual financial objectives.
    Although the worst of the Asian crisis appears to be behind us, new concerns
are always emerging. In the coming months, we'll likely hear more about how the
year 2000 computer problem may affect the markets or that we're overdue for a
correction. While the markets could undoubtedly suffer as a result of these or
any number of other events, we encourage you to focus on your long-term
investment goals. Although nothing is certain, history has shown us that over
time, the markets tend to recover--and most investors want to be positioned to
take advantage of any recovery.
    If you have concerns about market volatility or questions about how your
portfolio is structured to respond to these events, we encourage you to contact
your financial advisor. Your advisor can talk with you about sustaining a
long-term investment plan through a variety of market conditions. We hope that
Van Kampen Funds will play an important role as you and your advisor build a
portfolio designed to help you weather what the markets have in store.

Sincerely,


[SIG]

                               ECONOMIC SNAPSHOT

    The strength of the domestic economy continued to defy expectations in the
first half of 1999, although it finally began to show signs of slowing down.
Strong growth, healthy employment, and low inflation all contributed to the
favorable economic environment.

STRONG ECONOMIC GROWTH
    The nation's gross domestic product rose at an impressive rate of 4.3
percent during the first quarter of 1999, but fell to 2.3 percent in the second
quarter. The first-quarter expansion was fueled by an increase in consumer
spending, which dropped to more moderate levels later in the reporting period.

POSITIVE EMPLOYMENT ENVIRONMENT
    In May, the unemployment rate dropped to 4.2 percent--its lowest level in
more than 30 years. Throughout the reporting period, unemployment remained low,
the number of jobs grew, and wages rose. The labor market remained especially
tight in the service industry and most urban areas.

LOW INFLATION
    Inflation remained low throughout most of the reporting period, although a
sharp increase in oil prices contributed to a spike in April's consumer price
index report (CPI). Following this up-tick, the Federal Reserve raised interest
rates 0.25 percent on June 30. Although the Fed had expressed a bias toward a
series of rate increases, May's tame CPI report prompted it to drop this bias
when announcing the June rate increase.

ECONOMIC OUTLOOK
    Our outlook for the economy suggests that the moderate slowdown may
continue, bringing the economy back to historically normal growth levels.
Healthy job growth, which has been supporting the consumer confidence and
spending levels, showed signs of faltering toward the end of the reporting
period. However, a renewed optimism for corporate earnings, low unemployment,
and a vibrant housing market should provide some balance against a slower job
growth rate.

 TOTAL RETURNS
Life-of-Portfolio cumulative total return based on NAV(1)...     0.70%
Commencement date...........................................  04/30/99
</TABLE>

(1) Total return based on net asset value (NAV) assumes an investment at the
beginning of the period indicated, reinvestment of all distributions for the
period, and sale of all shares at the end of the period, all at NAV.

Total returns do not include any charges, expenses, or fees imposed by an
insurance company at the underlying portfolio or separate account levels. If the
returns included the effect of these additional charges, the returns would have
been lower.

An investment should be made with an understanding of the risks that an
investment in equity securities entails. These include the risk that the
financial condition of the issuers of the securities in the portfolio, or the
condition of the stock market in general, may worsen and therefore, the value of
Portfolio shares may decline. Past performance does not guarantee future
results. Investment return and net asset value will fluctuate with market
conditions. Portfolio shares, when redeemed, may be worth more or less than
their original cost.

Because the prices of common stocks and other securities fluctuate, the value of
an investment in the Portfolio will vary upon the Portfolio's investment
performance. Foreign securities may magnify volatility due to changes in foreign
exchange rates, the political and economic uncertainties in foreign countries,
and the potential lack of liquidity, government supervision, and regulation.

Market forecasts provided in this report may not necessarily come to pass.

The Portfolio being offered is through a variable annuity contract.

                          PORTFOLIO MANAGEMENT REVIEW

                               COMSTOCK PORTFOLIO

The following is an interview with the portfolio management team of the Van
Kampen Life Investment Trust--Comstock Portfolio. The team is led by B. Robert
Baker, Jr., senior portfolio manager, Jason Leder and Edie Terreson, portfolio
managers, and Stephen L. Boyd, chief investment officer for equity investments.
The following excerpts reflect their views on the Portfolio's performance since
its inception on April 30, 1999, through June 30, 1999.

Q     CAN YOU DESCRIBE THE STOCK MARKET ENVIRONMENT SINCE THE INCEPTION OF THE
      PORTFOLIO?

A     Investors displayed confidence in the U.S. stock market as global
      economies showed new strength and the domestic economy remained healthy.
      The Dow Jones Industrial Average broke past the 11,000 point milestone in
May and fluctuated in the upper 10,000 point range for the rest of the period.
For value-oriented portfolios such as the Comstock Portfolio, the second quarter
of 1999 was very favorable. Investors became more willing to pursue undervalued,
economically sensitive stocks rather than seek the perceived safety of blue-chip
growth companies, which they had preferred earlier in the year.

Q     WHAT WAS YOUR STRATEGY IN SEEKING TO MEET THE PORTFOLIO'S OBJECTIVE?

A     We consistently seek to invest in undervalued stocks that we believe have
      the potential for future price appreciation. To do this, we look for
      companies that are temporarily out of favor in the marketplace, meaning
their stock prices are lower than we believe they should be. Then, we apply
basic fundamental analysis to determine whether the company is sound and has the
potential to reach its fair value. When we find a company that we think is
undervalued and fundamentally sound, we consider adding it to the Portfolio.

Q     HOW HAVE YOU APPLIED THIS STRATEGY IN INVESTING THE PORTFOLIO'S NEW
      ASSETS?

A     The utility sector is currently an undervalued area of the market, so
      we've built up a significant weighting here. These stocks have struggled
      this year, although recently their performance has improved relative to
      the rest of the market. In accordance with our value strategy, we remain
heavily weighted in utilities because their valuations continue to be low and we
believe the fundamentals of this sector are attractive.
    Cyclical stocks--including commodities such as paper, oil, and other raw
materials--are also well represented in the Portfolio. Lately, these stocks have
been cheap compared to the rest of the market, so we invested substantially in
this area.

Q     WHICH STOCKS SUPPORTED PORTFOLIO PERFORMANCE?

A     Cyclical stocks performed well in the second quarter of 1999, and we saw
      favorable returns from paper company Boise Cascade and retailer Federated
      Department Stores. Other large holdings that have helped the Portfolio's
total return since inception included United HealthCare and Bell Atlantic.
Remember that not all stocks in the Portfolio performed well, and there is no
guarantee that any of these stocks will perform as well in the future.

Q     WHAT FACTORS WORKED AGAINST THE PORTFOLIO?

A     The sluggish performance of utility stocks year to date had a negative
      effect on the Portfolio. In addition, we were disappointed by one of our
      largest holdings, Tenet Healthcare, which has lost 21 percent since the
Portfolio's inception. This company is struggling with the challenges imposed by
managed care and changing Medicare reimbursement policies. On the plus side,
Tenet recently purchased a number of failing hospitals in the Philadelphia




                                        4
<PAGE>   6

area and has been turning them around faster than expected. We view Tenet as a
long-term holding and have maintained our investment.

Q     HOW DID THE PORTFOLIO PERFORM SINCE ITS INCEPTION?

A     From April 30, 1999, to June 30, 1999, the Portfolio achieved a total
      return of 0.70 percent(1). By comparison, the Standard & Poor's 500 Index
      returned 3.12 percent for the same period, and the Lipper Growth and
Income Fund Index, which more closely resembles the Portfolio, returned 2.62
percent. The S&P 500 Index is a broad-based, unmanaged index that reflects the
general performance of the stock market, and the Lipper Growth and Income Fund
Index reflects the average performance of the 30 largest growth and income
funds. Past performance is no guarantee of future results.
    Keep in mind that these indices are statistical composites that do not
include any commissions or sales charges that would be paid by an investor
purchasing the securities represented by these indices. Please refer to the
chart and footnotes on page 3 for additional Portfolio performance results.

Q     WHAT IS YOUR OUTLOOK FOR THE PORTFOLIO FOR THE REMAINDER OF THE YEAR?

A     The U.S. economy is still growing steadily and inflation remains subdued.
      In addition, overseas economies appear to be regaining their strength
      after two turbulent years. The U.S. stock market reflects these positive
conditions, as investors are showing a renewed interest in undervalued,
economically sensitive stocks. We will continue to be vigilant in assessing your
Portfolio's holdings as well as potential new investments in our efforts to
achieve the Portfolio's objective.

<TABLE>

</TABLE>

(1) Total return based on net asset value (NAV) assumes an investment at the
beginning of the period indicated, reinvestment of all distributions for the
period, and sale of all shares at the end of the period, all at NAV.

Total returns do not include any charges, expenses, or fees imposed by an
insurance company at the underlying portfolio or separate account levels. If the
returns included the effect of these additional charges, the returns would have
been lower.

See the Comparative Performance section of the current prospectus. An investment
should be made with an understanding of the risks that an investment in equity
securities entails. These include the risk that the financial condition of the
issuers of the securities in the portfolio, or the condition of the stock market
in general, may worsen and therefore, the value of Portfolio shares may decline.
Past performance does not guarantee future results. Investment return and net
asset value will fluctuate with market conditions. Portfolio shares, when
redeemed, may be worth more or less than their original cost.

Because the prices of common stocks and other securities fluctuate, the value of
an investment in the Portfolio will vary upon the Portfolio's investment
performance. Foreign securities may magnify volatility due to changes in foreign
exchange rates, the political and economic uncertainties in foreign countries,
and the potential lack of liquidity, government supervision, and regulation.

Market forecasts provided in this report may not necessarily come to pass.

The Portfolio being offered is through a variable annuity contract.

                          PORTFOLIO MANAGEMENT REVIEW

                           EMERGING GROWTH PORTFOLIO

The following is an interview with the portfolio management team of the Van
Kampen Life Investment Trust--Emerging Growth Portfolio. The team is led by Gary
M. Lewis, senior portfolio manager; Dudley Brickhouse, Janet Luby, and David
Walker, portfolio managers; and Stephen L. Boyd, chief investment officer for
equity investments.

Q     WHAT MARKET FACTORS AFFECTED THE PORTFOLIO DURING THE REPORTING PERIOD?

A     As has been its trademark recently, the stock market was volatile during
      the first six months of 1999. The Dow Jones Industrial Average passed two
      significant milestones during the reporting period--10,000 in late March
and 11,000 in early May. Small-cap stocks, measured by the Russell 2000,
performed solidly if not spectacularly during the six months, as most of the
market's upward movement was propelled by larger stocks. Investors' anticipation
of an interest-rate increase placed downward pressure on the stock market late
in the reporting period, particularly among growth stocks. In response to this
shift from growth investments, investors began to favor cyclical stocks. The
Federal Reserve did indeed raise interest rates on the last day of the reporting
period, but, because the increase was widely expected, the effect on stock
prices was limited.

Q     SO HOW DID YOU MANAGE THE PORTFOLIO IN RESPONSE TO THESE EVENTS?

A     Our investment strategy has worked well for us in the past, so we didn't
      alter our stock-selection approach when market conditions shifted. As
      always, our technique was to look for stocks with rising earnings
expectations and rising valuations, and we invested in those companies we
believed had the potential to outperform earnings expectations. Conversely, we
sold stocks if their underlying companies' earnings estimates or valuations were
declining. We consistently manage the Portfolio from the "bottom up," meaning
that we evaluate each company individually before deciding to invest.
    As the reporting period went on, it became increasingly difficult to
identify stocks that met our investment criteria. That's because the market
began to favor cyclical stocks in the last few months of the reporting period.
As a result, we moved into a handful of cyclical stocks with high-growth
characteristics.

Q     WHAT WERE SOME OF THE PORTFOLIO'S BEST PERFORMERS DURING THE PERIOD?

A     Companies involved in wireless communications were particularly successful
      investments for the Portfolio. This is a burgeoning market, and these
      companies are benefiting greatly from the transition from analog to
      digital systems. During the reporting period we purchased Qualcomm, which
was one of the Portfolio's best performers. Leading cellular phone manufacturer
Nokia continued to be a mainstay of the Portfolio and performed very well during
the reporting period, as did RF Micro Devices, a component supplier to Nokia.
    Many Internet companies continued to appreciate in value, although we
shifted our focus from service companies to firms that provide the Internet's
infrastructure. Holdings from this area that helped the Portfolio's return
included Exodus Communications, Cisco Systems, Broadcom, and Uniphase.
    The performance of the Portfolio was also enhanced significantly by VISX, a
leading manufacturer of equipment used for laser vision-correction; Gemstar
International, best known for its VCR Plus+ product; and Echostar
Communications, a company providing direct-broadcast satellite-television
service.
    We also found success with a number of our retail holdings--especially those
that could capitalize on consumer demand for technology. Companies like Tandy
and Circuit City, newly purchased during the period, and Best Buy, a longtime
holding in the Portfolio, performed very well because they were beneficiaries of
this increased demand.

<PAGE>   15

Q     DID ANY STOCKS HURT THE PORTFOLIO?

A     Some technology stocks were hurt by concerns about the year 2000
      phenomenon--namely, that corporate spending on computer hardware,
      software, and services would slow down in the face of companies' need to
focus on critical year 2000 projects. Technology companies whose performance
suffered included Compuware, Legato Systems, and New Era of Networks. We sold
our position in Dell Computer, not only because of concerns about the year 2000
problem, but also because intense price competition in the personal-computer
market helped drive down the company's stock price and led to downward revisions
of Dell's estimated earnings.
    Other disappointments included cable, satellite, and on-line
service-provider CSG Systems and Tricon Global, the restaurant company chain
that manages Kentucky Fried Chicken, Pizza Hut, and Taco Bell. Financial
services companies were relative underperformers during the reporting period as
fears of an interest-rate hike weighed on the sector. Examples of laggards in
this area were banking companies such as Firstar, Fifth Third Bancorp, and
Amsouth Bancorporation.

Q     HOW DID THE PORTFOLIO PERFORM OVERALL?

A     As a result of our successful stock selection--especially in the
      technology area--the Portfolio performed extremely well, achieving a
      six-month total return of 21.97 percent(1) as of June 30, 1999. By
      comparison the Standard & Poor's 400 MidCap Index returned 6.86 percent,
and the Russell 2000 Index returned 9.28 percent.
    The Portfolio invests primarily in companies whose market capitalizations
fall within the range of the companies composing the Standard & Poor's 400
MidCap Index. This range is between approximately $247 million and $11 billion,
as of June 30, 1999. The S&P 400 MidCap Index is a broad-based index that
reflects the general performance of 400 domestic mid-cap stocks, and the Russell
2000 Index reflects the general performance of small-cap stocks. These indices
are statistical composites that do not include any commissions or sales charges
that would be paid by an investor purchasing the securities or investments
represented by these indices. Please refer to the chart and footnotes on page 12
for additional portfolio performance results. Past performance does not
guarantee future results.

Q     WHAT DO YOU SEE AHEAD FOR THE PORTFOLIO THROUGH THE END OF THE YEAR?

A     We're anticipating that continued market volatility will have an impact on
      the Portfolio. Concerns about interest rates will make for an interesting
      next six months, and questions about the year 2000 problem will affect
investors' decisions--although to what extent is uncertain. We do think that
corporate spending on the year 2000 problem will lead to a slowdown in the
software industry, because firms may delay their purchases of new software until
after the new year. Also, we continue to adjust to a new "day trading" stock
market culture, which has led to a new standard of volatility.
    Through all of these situations, we will continue to do what has worked well
for us in the past, which is invest according to our discipline. In volatile
times our job is more difficult because it can be challenging to find stocks
that meet our criteria. In that case, we search harder for stocks whose
valuations are increasing or for those stocks whose valuations are declining the
least. Either way, we have confidence in our investment strategy and stick with
it during all types of market conditions.

(1)Total return based on net asset value (NAV) assumes an investment at the
beginning of the period indicated, reinvestment of all distributions for the
period, and sale of all shares at the end of the period, all at NAV.

Total returns do not include any charges, expenses, or fees imposed by an
insurance company at the underlying portfolio or separate account levels. If the
returns included the effect of these additional charges, the returns would have
been lower.

See the Comparative Performance section of the current prospectus. An investment
should be made with an understanding of the risks that an investment in equity
securities entails. These include the risk that the financial condition of the
issuers of the securities in the portfolio, or the condition of the stock market
in general, may worsen and therefore, the value of Portfolio shares may decline.
Past performance does not guarantee future results. Investment return and net
asset value will fluctuate with market conditions. Portfolio shares, when
redeemed, may be worth more or less than their original cost.

Because the prices of common stocks and other securities fluctuate, the value of
an investment in the Portfolio will vary upon the Portfolio's investment
performance. Foreign securities may magnify volatility due to changes in foreign
exchange rates, the political and economic uncertainties in foreign countries,
and the potential lack of liquidity, government supervision, and regulation.

Market forecasts provided in this report may not necessarily come to pass.

The Portfolio being offered is through a variable annuity contract.

                          PORTFOLIO MANAGEMENT REVIEW

                              ENTERPRISE PORTFOLIO

The following is an interview with the portfolio management team of the Van
Kampen Life Investment Trust--Enterprise Portfolio. The team includes Jeff D.
New, senior portfolio manager; Michael Davis and Mary Jayne Maly, portfolio
managers; and Stephen L. Boyd, chief investment officer for equity investments.

Q     WHAT MARKET FACTORS AFFECTED THE PORTFOLIO DURING THE REPORTING PERIOD?

A     As has been its trademark recently, the stock market was volatile during
      the first six months of 1999. The Dow Jones Industrial Average passed two
      significant milestones during the reporting period--10,000 in late March
and 11,000 in early May. Investors' anticipation of an interest-rate increase
placed downward pressure on the stock market, particularly among growth stocks.
In response to this shift from growth investments, investors began to favor
cyclical stocks. The Federal Reserve did indeed raise interest rates on the last
day of the reporting period, but, because the increase was widely expected, the
effect on stock prices was limited.

Q     SO HOW DID YOU MANAGE THE PORTFOLIO IN RESPONSE TO THESE EVENTS?

A     As we have stressed in prior reports, our investment discipline leads us
      to purchase stocks that meet our criteria of positive future fundamentals
      and attractive current prices. By our definition, a company with positive
future fundamentals possesses at least one of the following traits: consistent
earnings growth; accelerating earnings growth; better-than-expected
fundamentals; or an underlying change in a company, industry, or regulatory
environment. We evaluate stocks from the "bottom up"--in other words, on a
company by company basis. Because our investment approach has served the
Portfolio well through a broad range of economic conditions, we weren't tempted
to change our strategy during the past six months.
    That said, we did seek to adjust to changing market conditions in the last
several months of the reporting period. For example, we attempted to capitalize
on the recent upturn among cyclical stocks by adding several that clearly met
our investment discipline. This helped moderate the Portfolio's performance
during a difficult period for growth stocks.

Q     WHAT WERE SOME OF THE PORTFOLIO'S BEST PERFORMERS DURING THE PERIOD, AND
      HOW DID THEY AFFECT TOTAL RETURN?

A     We were pleased with our investments in semiconductor companies--their
      stocks are sensitive to global economic conditions, which have been
      relatively strong in recent months. The Portfolio's total return benefited
greatly from our owning these stocks--especially Texas Instruments, a
semiconductor maker that develops a key component in cellular phones. Other
semiconductor stocks whose performance boosted the Portfolio's performance were
Intel, a computer-chip manufacturer; Applied Materials, which sells equipment
used to manufacture semiconductors; and STMicroelectronics, a maker of
integrated circuits, devices used in a wide variety of microelectronic
applications. Another stock that helped the Portfolio's return was Univision,
the leading Spanish-language television broadcaster in the United States. This
network, which reaches 92 percent of the U.S. Hispanic market, saw its stock
price appreciate 81 percent during the reporting period. One of our best
investments was Tricon Global, which operates restaurants under the Pizza Hut,
Taco Bell, and Kentucky Fried Chicken brands.

Q     WHAT WAS SO SUCCESSFUL ABOUT YOUR INVESTMENT IN TRICON GLOBAL?

A     We purchased this stock in late 1998 because we were optimistic about
      management's plan to improve operations, sell nonproductive stores back to
      franchisees, and use proceeds to repay debt. As we expected, earnings
increased dramatically as a result of this plan, and our stock appreciated
nearly 56 percent through late April, when we sold our position. We chose to
sell when the company failed to exceed earnings expectations in April--this
failure violated our requirement to own only companies with accelerated earnings
growth. This turned out to be a very



                                       22
<PAGE>   24

good decision, as the stock began a steady decline thereafter. The Portfolio's
return, therefore, benefited directly from the stock's rapid appreciation, and
indirectly from our timely sale.

    Please keep in mind that not all stocks in the Portfolio performed as well
as Tricon Global or the others mentioned above, nor is there any guarantee that
these stocks will perform as well in the future.

Q     DID ANY STOCKS DISAPPOINT YOU?

A     Yes, we were disappointed in our holdings in the areas of health care and
      grocery stores. A number of stocks in these industries underperformed and
      hurt the Portfolio's return.
    Drug companies in particular were poor performers. Our holdings included
industry leaders Schering-Plough and Pfizer, as well as smaller companies such
as Watson Pharmaceuticals and Lincare. Pharmaceutical companies, which typically
aren't affected by changes in the economy, fared very well in 1998 as investors
sought refuge from market volatility. These stocks have languished, however, as
we near the 2000 elections, which could precipitate additional health-care
regulations. This belief has placed a cloud over drug company stocks, although
we still think the long-term prospects for this sector are excellent.
    Grocery store stocks also had a negative impact on the Portfolio's return.
These included Safeway and Kroger, two of our longtime holdings. Although these
companies still appear to be executing their business plans well, their stock
prices have suffered in recent months--reflecting concern that acquisitions in
this area are slowing.

Q     HOW DID THE PORTFOLIO PERFORM?

A     Strong stock selection from a variety of sectors partially offset the
      downward pressure on growth stocks during the period. The Portfolio
      achieved a six-month total return of 6.66 percent(1) as of June 30, 1999.
      By comparison, the Standard & Poor's 500 Index returned 12.36 percent, and
the Lipper Growth Fund Index, which more closely resembles the Portfolio,
returned 11.89 percent. The S&P 500 Index is a broad-based, unmanaged index that
reflects the general performance of the stock market, and the Lipper Growth Fund
Index reflects the average performance of the 30 largest growth funds. Past
performance does not guarantee future results.
    These indices are statistical composites that don't include any commissions
or sales charges that would be paid by an investor purchasing the securities
represented by these indices. Please refer to the footnotes and chart on page 21
for additional Portfolio performance results.

Q     WHAT DO YOU SEE AHEAD FOR THE PORTFOLIO?

A     We are cautiously optimistic that corporate earnings will continue to
      improve and that many international economies are beginning to emerge from
      last year's depths. Despite subtle indications that prices may be creeping
upwards, inflation is still low and economic growth is strong, which is a
promising sign for the stock market.
    Our major concern is that stock-market valuations remain high by relative
and historical measures. Maintaining those levels depends on more good news with
respect to inflation and earnings. As long as both remain favorable, we expect
the market--and the Portfolio--to still perform well. However, high valuations
leave stocks vulnerable if economic conditions change. We will continue to
monitor the situation as we stick to the discipline that has worked well for us
in the past.

(1)Total return based on net asset value (NAV) assumes an investment at the
beginning of the period indicated, reinvestment of all distributions for the
period, and sale of all shares at the end of the period, all at NAV.

Total returns do not include any charges, expenses, or fees imposed by an
insurance company at the underlying portfolio or separate account levels. If the
returns included the effect of these additional charges, the returns would have
been lower.

See the Comparative Performance section of the current prospectus. An investment
should be made with an understanding of the risks that an investment in equity
securities entails. These include the risk that the financial condition of the
issuers of the securities in the portfolio, or the condition of the stock market
in general, may worsen and therefore, the value of Portfolio shares may decline.
Past performance does not guarantee future results. Investment return and net
asset value will fluctuate with market conditions. Portfolio shares, when
redeemed, may be worth more or less than their original cost.

Because the prices of common stocks and other securities fluctuate, the value of
an investment in the Portfolio will vary upon the Portfolio's investment
performance. Foreign securities may magnify volatility due to changes in foreign
exchange rates, the political and economic uncertainties in foreign countries,
and the potential lack of liquidity, government supervision, and regulation.

Market forecasts provided in this report may not necessarily come to pass.

The Portfolio being offered is through a variable annuity contract.

                          PORTFOLIO MANAGEMENT REVIEW

                          GROWTH AND INCOME PORTFOLIO

The following is an interview with the portfolio management team of Van Kampen
Life Investment Trust--Growth and Income Portfolio. The team is led by James A.
Gilligan, senior portfolio manager, Scott Carroll and James Roeder, portfolio
managers; and Stephen L. Boyd, chief investment officer for equity investments.

Q     HOW WOULD YOU DESCRIBE THE MARKET ENVIRONMENT IN WHICH THE PORTFOLIO
      OPERATED DURING THIS SIX-MONTH PERIOD?

A     It's been an explosive market. As global growth strengthened, investors
      gained confidence in the domestic economy. Fueled by new money, the stock
      market soared to record highs, breaking through the 10,000 point ceiling
and pushing past 11,000. However, investors found cause for concern when
interest rates began to creep higher in the second quarter of 1999. These fears
were only heightened when the Fed announced its bias toward tightening
short-term interest rates, which increased market volatility. Calm was restored
in the final hours of the reporting period, as the Fed raised rates by 0.25
percent but indicated that additional increases were unnecessary due to tame
inflation and healthy economic growth.
    In the first quarter, the booming stock market created a very challenging
environment for a value-oriented portfolio such as this one, as growth-oriented
investments stole the spotlight. In April, however, investors took note of the
rising economy and turned their attention toward cyclical stocks. Cyclical
stocks tend to perform well in a strong economic environment, and this group
began to outperform large-capitalization growth stocks for the first time in
nearly three years. Because cyclical stocks had been undervalued relative to the
broad market, this change in investor sentiment provided a favorable environment
for the Portfolio.

Q     BASED ON THIS ASSESSMENT, HOW AND WHERE DID YOU FIND INVESTMENTS?

A     In our search for good value investments, we continued to focus on
      companies that we believe are underappreciated by the market but
      demonstrate a catalyst for positive change. We might examine a troubled
company that's recently come under new management, or study a sector that has
fallen out of favor but exhibits solid fundamentals for recovery.
    For example, in your last report, we described the troubles that had
befallen many financial companies because of economic turmoil overseas. As many
global economies began to recover, we revisited the financial sector during the
past six months and selected several large financial companies that we believed
were in good positions to take advantage of this recovery. We adjusted our
positions in The Equitable, Citigroup, and Chase Manhattan because of potential
volatility, and added a position in Bank of America, which we felt was less
volatile than some of the bigger money-center banks. We also added two new
financial companies to the portfolio--Lincoln National and Marsh &
McLennan--both of which have reasonable valuations and have recently appointed
new chief executive officers.

Q     IN WHAT OTHER AREAS WERE YOU SUCCESSFUL IN YOUR SEARCH FOR VALUE?

A     We looked for turnaround stories in the technology sector, which
      demonstrated the capacity for a strong rebound during the period. We were
      especially interested in some of the technology areas that weren't part of
last year's market surge. For example, our position in Adobe was one of the best
performers. We also invested successfully in Motorola and QualComm, although we
eliminated the latter when we believed the stock had reached its price target.
Computer hardware giant IBM continues to be one of the portfolio's largest
positions, although our holding in this company fluctuated based on some
variable quarterly earnings reports.
    In the consumer nondurables sector, we focused our attention on a relatively
new area to the portfolio: beverage companies. These included Anheuser-Busch,
Pepsi Bottling Company, and Whitman, another bottling company. Although we
occasionally moderated our positions in these holdings during the period, we
were attracted to the high volume and attractive pricing of this industry.
Although we might say the same for Philip Morris, which used to be one of our

                                       31
<PAGE>   33

largest holdings, we reduced that position dramatically. With continuing clouds
of litigation hanging over the company, we were unable to identify a catalyst
for improvement in the stock's price.

Q     WERE THERE ANY OTHER DISAPPOINTMENTS IN THE PORTFOLIO?

A     One of our largest sector exposures, health care--in particular,
      pharmaceutical companies--fell out of favor with investors during this
      six-month period. As a result, we decreased our exposure to pharmaceutical
companies and focused on stocks that we believe are best positioned to take
advantage of a recovery in the health-care sector. Because HMOs (health
maintenance organizations) began to see improved performance, the Portfolio's
return benefited from a significant position in United HealthCare, as well as
holdings in Oxford Health Plans and Aetna.
    We also continued to analyze health-care service companies--such as nursing
home provider HCR Manor Care, in which we established a small position. These
companies have come under significant financial pressure because of changes in
the way they are reimbursed for Medicare payments. However, we are optimistic
about their potential for recovery, as they serve a very important role in the
industry. We expect to add to this area if we find additional value
opportunities.

Q     TAKING EVERYTHING INTO CONSIDERATION, HOW DID THE PORTFOLIO PERFORM DURING
      THE REPORTING PERIOD?

A     Although some of our holdings in the health-care sector hurt the
      Portfolio's return, we also enjoyed some impressive gains in the financial
      and technology sectors. As a result, the Portfolio achieved a total return
      of 10.20 percent(1) for the six-month period ended June 30, 1999. By
comparison, the Standard & Poor's 500 Index returned 12.36 percent for the same
period. The S&P 500 Index is a broad-based index that reflects the general
performance of the stock market; this statistical composite does not reflect any
commissions or sales charges that would be paid by an investor purchasing the
securities it represents. Of course, past performance is no guarantee of
comparable future results. Please refer to the chart and footnotes on page 30
for additional Portfolio performance results.

Q     WHAT DO YOU SEE HAPPENING IN THE MARKET OVER THE COMING MONTHS?

A     We take some reassurance in the fact that inflation is still low and the
      economy remains strong. Although these factors support a healthy stock
      market, the slow recovery of the bond market gives us reason to maintain a
cautious perspective. We've come to expect market volatility regardless of
strong economic fundamentals, if only because the Dow's current level is so
high. We hope that volatility will initiate investors' return to a broader range
of stocks within the market. In this environment, our bottom-up analysis and
disciplined value criteria may help us uncover fresh investment opportunities.
We'll continue to emphasize securities that we feel exhibit potential for
improvement with limited downside risk.

(1)Total return based on net asset value (NAV) assumes an investment at the
beginning of the period indicated, reinvestment of all distributions for the
period, and sale of all shares at the end of the period, all at NAV.

Total returns do not include any charges, expenses, or fees imposed by an
insurance company at the underlying portfolio or separate account levels. If the
returns included the effect of these additional charges, the returns would have
been lower.

See the Comparative Performance section of the current prospectus. An investment
should be made with an understanding of the risks that an investment in equity
securities entails. These include the risk that the financial condition of the
issuers of the securities in the portfolio, or the condition of the stock market
in general, may worsen and therefore, the value of Portfolio shares may decline.
Past performance does not guarantee future results. Investment return and net
asset value will fluctuate with market conditions. Portfolio shares, when
redeemed, may be worth more or less than their original cost.

Because the prices of common stocks and other securities fluctuate, the value of
an investment in the Portfolio will vary upon the Portfolio's investment
performance. Foreign securities may magnify volatility due to changes in foreign
exchange rates, the political and economic uncertainties in foreign countries,
and the potential lack of liquidity, government supervision, and regulation.

Market forecasts provided in this report may not necessarily come to pass.

Investing in REITs involves unique risks in addition to those risks associated
with investing in the real estate industry in general. Equity REITs may be
affected by changes in the value of the underlying property owned by the REITs,
while mortgage REITs may be affected by the quality of any credit extended.
REITs are dependent upon management skills, are not diversified and are subject
to the risks of financing projects. REITs are subject to heavy cash flow
dependency, default by borrowers, self-liquidation and the possibilities of
failing to qualify for tax-exempt status under the Internal Revenue Code of
1986, as amended. REITs, especially mortgage REITs, are also subject to some
interest rate risk (e.g., as interest rates rise, the value of REITs may
decline).

The Portfolio being offered is through a variable annuity contract.

                          PORTFOLIO MANAGEMENT REVIEW

                MORGAN STANLEY REAL ESTATE SECURITIES PORTFOLIO

The following is an interview with Theodore R. Bigman, portfolio manager of Van
Kampen Life Investment Trust--Morgan Stanley Real Estate Securities Portfolio.

Q     WHAT WERE THE MARKET CONDITIONS IN WHICH THE PORTFOLIO OPERATED DURING THE
      REPORTING PERIOD?

A     After a difficult first quarter, in which we saw a continuation of the
      negative market conditions from 1998, the REIT market finally experienced
      recovery in the second quarter of 1999. The vast majority of this
      turnaround was achieved from mid-April to mid-May due largely to a
dramatic change in leadership in the equity markets--investors finally turned
away from the richly valued large-cap growth and Internet stocks toward the
beaten-down cyclical and value stocks. This change was primarily the result of
economic consensus that the global economy had begun to recover. However, the
real estate market modestly regressed in the latter part of the reporting period
due to fears of a Federal Reserve tightening.
    Unlike prior rallies, this REIT recovery was broad-based, lifting stocks in
all sectors. Even after this constructive period, REITs are still trading at a
slight discount to the underlying value of their assets. This means that it is
generally more attractive to buy real estate on Wall Street (through the
ownership of securities) than on Main Street (through the direct ownership of
properties).

Q     HOW WERE THE FUNDAMENTALS OF THE REAL ESTATE MARKET AFFECTED?

A     Although real estate cycles tend to move at a slow pace, the U.S. real
      estate market has typically featured boom and bust cycles. Given the
      increasing size of the public markets for real estate equity and debt,
      there appears to be the opportunity for a muting of those cycles as the
scrutiny and attention on the potential for over-supplied markets has increased.
We base this belief on the current balance of supply and demand, as robust
levels of demand have served to mute any serious threat of oversupply.
Specifically, fundamentals in apartment and retail markets grew stronger during
the period, while the dramatic improvement in commercial markets showed signs of
reaching a plateau.

Q     HOW DID YOU POSITION THE PORTFOLIO DURING THIS TIME?

A     We continued to shape the Portfolio with companies that offer attractive
      fundamental valuations relative to their underlying real estate value.
      Throughout the year, we were encouraged by the undeniable strength of the
      U.S. economy and became more optimistic that real estate fundamentals will
remain favorable. While the sector weightings remain very similar to the
Portfolio's profile six months ago, we have been more willing to take
opportunistic positions in certain areas, including hotels and offices.
Generally, we took advantage of the REIT rally to upgrade the quality of the
Portfolio. This is most notably evident in the office sector, where we sold some
of our holdings in the suburban office sector and added to the central business
district office sector.
    The Portfolio's relative outperformance during the reporting period was
driven primarily by stock selection. Specifically, the Portfolio benefited from
investments in two West Coast apartment stocks and two retail companies--one
focused on grocery-anchored centers and the other on upscale malls. The
Portfolio's return was also supported by large positions in two office stocks
trading at significant discounts to their underlying asset value.

<PAGE>   42

Q     WHAT WAS THE PORTFOLIO'S PERFORMANCE FOR THE SIX-MONTH PERIOD?

A     The Portfolio achieved a total return of 8.50 percent(1) for the six-month
      period ended June 30, 1999. This performance compares favorably to the
      total return of the NAREIT (National Association of Real Estate Investment
Trusts) Equity REIT Index of 2.06 percent over the same period. The NAREIT Index
reflects the performance of a broad range of equity REITs of all property types.
    By comparison, the Standard & Poor's 500 Index registered a total return of
12.36 percent for the six months ended June 30, 1999. The S&P 500 Index is a
broad-based, unmanaged index that reflects the general performance of the stock
market. Keep in mind that these indices are unmanaged statistical composites
that do not reflect any commissions or sales charges that would be incurred by
an investor purchasing the securities they represent. Of course, past
performance is no guarantee of comparable future results. Please refer to the
chart and footnotes on page 39 for additional Portfolio performance results.

Q     WHAT IS YOUR OUTLOOK FOR THE REAL ESTATE MARKET?

A     We are encouraged by the general sentiment among industry investors that
      the real estate market is stable, even bordering on boring. It's a nice
      middle ground between the unsustainable euphoria of years past and the
more recent sense of depression. We can attribute this shift in attitude to two
key factors. First, most REITs have developed business plans that do not require
equity issuance in 1999. Generally, these business plans place an emphasis on
managing the existing portfolio, while any external growth is limited to core
competencies. REIT management companies are pleased with the recovery in their
share prices but have declined to issue new equity at current prices. Second, at
the end of the first-quarter earnings season, companies reported strong internal
cash flow as a result of favorable property fundamentals. Because fundamentals
remain intact, we do not expect any significant variation in the results for the
second quarter.
    We believe this return to stability will help calm current investors and
attract new investors looking for real estate exposure. It may also invite
non-dedicated investors looking for long-term growth of capital with only a
modest correlation to the broad equity markets.

</TABLE>

(1)Total return based on net asset value (NAV) assumes an investment at the
beginning of the period indicated, reinvestment of all distributions for the
period, and sale of all shares at the end of the period, all at NAV.

Total returns do not include any charges, expenses, or fees imposed by an
insurance company at the underlying portfolio or separate account levels. If the
returns included the effect of these additional charges, the returns would have
been lower.

See the Comparative Performance section of the current prospectus. An investment
should be made with an understanding of the risks that an investment in equity
securities entails. These include the risk that the financial condition of the
issuers of the securities in the portfolio, or the condition of the stock market
in general, may worsen and therefore, the value of Portfolio shares may decline.
Past performance does not guarantee future results. Investment return and net
asset value will fluctuate with market conditions. Portfolio shares, when
redeemed, may be worth more or less than their original cost.

Because the prices of common stocks and other securities fluctuate, the value of
an investment in the Portfolio will vary upon the Portfolio's investment
performance. Foreign securities may magnify volatility due to changes in foreign
exchange rates, the political and economic uncertainties in foreign countries,
and the potential lack of liquidity, government supervision, and regulation.

Market forecasts provided in this report may not necessarily come to pass.

The Portfolio being offered is through a variable annuity contract.

                          PORTFOLIO MANAGEMENT REVIEW

                           STRATEGIC STOCK PORTFOLIO

The following is an interview with the portfolio management team of the Van
Kampen Life Investment Trust--Strategic Stock Portfolio. The team is led by John
M. Cunniff, senior portfolio manager, Raj Wagle, portfolio manager (since May
1999), and Stephen L. Boyd, chief investment officer for equity investments.

Q     WHAT MARKET FACTORS AFFECTED THE PORTFOLIO DURING THE REPORTING PERIOD?

A     As has been its trademark recently, the stock market was volatile during
      the first six months of 1999. The Dow Jones Industrial Average passed two
      significant milestones during the reporting period--10,000 in late March
and 11,000 in early May. Investors' anticipation of an interest-rate increase
placed downward pressure on the stock market, particularly among growth stocks.
In response to this shift from growth investments, investors began to favor
cyclical stocks. The Federal Reserve Board did indeed raise interest rates on
the last day of the reporting period, but, because the increase was widely
expected, the effect on stock prices was limited.

Q     HOW DID YOU SEEK TO MEET THE PORTFOLIO'S OBJECTIVE?

A     We use a disciplined strategy to select undervalued stocks of high-quality
      companies. First, we analyze the Dow, which is composed of 30 blue-chip
      stocks. Each month, we invest half of the Portfolio's new assets into
equal amounts of the 10 Dow stocks with the highest dividend-yields. Investors
often refer to this as a "Dogs of the Dow" strategy.
    Next, we review the nearly 370 large-company stocks that comprise the Morgan
Stanley Capital International-USA Index. We exclude the 30 stocks of the Dow and
all utility and financial stocks. The remaining securities are screened for
quality factors, such as sales growth, earnings growth, dividend performance,
and trading volume. Of the securities that pass our screen, we select the 10
stocks with the highest dividend yields. The other half of the Portfolio's new
assets are invested in equal amounts of these 10 stocks each month.
    By limiting our investments to these two indices, we select from a pool of
high-quality U.S. companies. Also, because stocks with high dividend-yields tend
to be undervalued, our strategy pinpoints companies that could potentially
rebound in price.

Q     HOW DOES THE STRATEGY WORK OVER TIME?

A     Every month, we purchase 20 stocks--10 from the Dow and 10 from the
      MSCI-USA Index--so the Portfolio has 12 "baskets" containing 20 stocks
      each. Each basket is sold after 12 months, and a new basket of 20 stocks
is purchased to replace it. It is important to understand that shareholders of
the Portfolio don't own just one basket of stocks but instead own shares of the
whole Portfolio, which contains multiple baskets.
    Through this stock selection process, the Portfolio is rotated every month
to purchase stocks that may be undervalued in the marketplace and sell stocks
that have had a full 12 months to potentially rebound to their fair values. It
has been our experience that solid, well-established companies do not often
languish at reduced valuations. Their true worth is usually recognized over
time.

Q     WHICH STOCKS HAD THE GREATEST POSITIVE IMPACT ON THE PORTFOLIO'S
      PERFORMANCE?

A     The Portfolio's largest holdings and biggest contributors to positive
      performance were stocks that passed our screens during multiple months and
      therefore were purchased repeatedly throughout the year. The stocks that
most significantly contributed to the total return for the six-month period
included Limited, JP Morgan, Caterpillar, Minnesota Mining & Manufacturing, and
Du Pont. All of these companies benefited from the continuing economic
expansion. This growth has fueled consumer retailers, such as Limited. It has
also enabled financial stocks, such as

                                       48
<PAGE>   50

JP Morgan, to recover from last fall's global economic crisis. And, most
directly, economic expansion has fueled earnings increases at industrial
companies such as Caterpillar, Minnesota Mining & Manufacturing, and Du Pont.
    Please keep in mind that not all stocks in the Portfolio performed as
favorably, nor is there any guarantee they will continue to do so in the future.

Q     WHAT INVESTMENTS MOST HURT THE PORTFOLIO?

A     Philip Morris stands out as the worst contributor to the total return of
      the Portfolio during this period. Concerns about ongoing litigation
      continued to trouble investors, leading to Philip Morris's
      underperformance. Because of the stock's high dividend yield, Philip
Morris represented a relatively large portion of the Portfolio and therefore had
a substantial impact on the Portfolio's return.

Q     HOW DID THE PORTFOLIO PERFORM DURING THE REPORTING PERIOD?

A     Due to the generally positive performance during the reporting period of
      the types of stocks that meet the Portfolio's discipline, the Portfolio
      achieved a six-month total return of 11.50 percent(1) as of June 30, 1999.
      By comparison, the Standard & Poor's 500 Index returned 12.36 percent, the
Dow Jones Industrial Average returned 20.46 percent, and the MSCI-USA Index
returned 11.95 percent for the same period. Past performance does not guarantee
future results.
    The S&P 500 Index is a broad-based, unmanaged index that reflects the
general performance of the stock market. The Dow consists of 30 actively traded
stocks of well-established, blue-chip companies, and the MSCI-USA Index achieves
a 60 percent representation of U.S. market capitalization, as well as 60 percent
of the capitalization of each industry group. These indices are statistical
composites that do not include any commissions that would be paid by an investor
purchasing the securities represented by these indices. Please refer to the
chart and footnotes on page 47 for additional performance results.

Q     WHAT DO YOU SEE AHEAD FOR THE PORTFOLIO?

A     We're anticipating continued market volatility. Concerns about interest
      rates will make for interesting times ahead, and questions about the year
      2000 problem will affect investors' decisions--although to what extent is
uncertain. As we've mentioned in prior reports, during periods of market
uncertainty, investors often look to purchase stock in large, well-established
companies with a history of high dividend-yields. We believe that the Strategic
Stock Portfolio, which purchases stock in only these types of companies, may
represent an attractive option for such investors.

1. SIGNIFICANT ACCOUNTING POLICIES
Van Kampen Life Investment Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended, as a diversified open-end management
investment company comprised of eleven Portfolios: Asset Allocation Portfolio(1)
("Asset Allocation"), Comstock Portfolio ("Comstock"), Domestic Income
Portfolio(1) ("Domestic"), Emerging Growth Portfolio ("Emerging Growth"),
Enterprise Portfolio ("Enterprise"), Global Equity Portfolio(1) ("Global
Equity"), Government Portfolio(1) ("Government"), Growth and Income Portfolio
("Growth and Income"), Money Market Portfolio(1) ("Money Market"), Morgan
Stanley Real Estate Securities Portfolio ("Real Estate") and Strategic Stock
Portfolio ("Strategic Stock") (collectively the "Portfolios"). Each Portfolio is
accounted for as a separate entity.
    The goals of the Portfolios are as follows: Asset Allocation seeks a high
total investment return consistent with prudent risk; Comstock seeks capital
growth and income through investments in equity securities including common and
preferred stocks and securities convertible into common and preferred stocks;
Domestic seeks income as its primary objective and capital appreciation as a
secondary objective; Emerging Growth seeks capital appreciation by investing
principally in common stocks of small and medium sized companies; Enterprise
seeks capital appreciation by investing principally in common stocks; Global
Equity seeks long-term growth of capital through an internationally diversified
portfolio of equity securities of any nation, including the United States;
Government seeks high current return consistent with preservation of capital;
Growth and Income seeks long-term growth of capital and income by investing
primarily in income-producing equity securities including common stocks and
convertible securities; Money Market seeks protection of capital and high
current income by investing in short-term money market instruments; Real Estate
seeks long-term growth of capital by investing principally in securities of
companies operating in the real estate industry; and Strategic Stock seeks an
above average total return consistent with the preservation of invested capital,
by investing primarily in a portfolio of dividend paying equity securities
included in the Dow Jones Industrial Average or the Morgan Stanley Capital
International USA Index.
    The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION--Investments in securities listed on a securities exchange
are valued at their sales price as of the close of such securities exchange.
Fixed income investments are valued by independent pricing services or dealers
using the mean of the bid and asked prices. Unlisted securities and listed
securities for which the last sales price is not available are valued at the
mean of the bid and asked prices. For those securities where prices or
quotations are not available, valuations are determined in accordance with
procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of 60 days or less are valued at amortized
cost.

B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Portfolios may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolios will maintain, in a segregated account with its custodian, assets
having an aggregate value at least equal to the amount of the when issued or
delayed delivery purchase commitments until payment is made.
    The Portfolios may invest in repurchase agreements which are short-term
investments in which the Portfolios acquire ownership of a debt security and the
seller agrees to repurchase the security at a future time and specified price.
The Portfolios may invest independently in repurchase agreements, or transfer
uninvested cash balances into a pooled cash account along with other investment
companies advised by Van Kampen Asset Management Inc. (the

"Adviser") or its affiliates, the daily aggregate of which is invested in
repurchase agreements. Repurchase agreements are fully collateralized by the
underlying debt security. The Portfolios will make payment for such securities
only upon physical delivery or evidence of book entry transfer to the account of
the custodian bank. The seller is required to maintain the value of the
underlying security at not less than the repurchase proceeds due the Portfolios.

C. INCOME AND EXPENSES--Dividend income is recorded on the ex-dividend date and
interest income is recorded on an accrual basis. Discounts on debt securities
purchased are amortized over the expected life of each applicable security.
Premiums on debt securities are not amortized.

D. ORGANIZATIONAL COSTS--Emerging Growth, Real Estate and Strategic Stock have
reimbursed Van Kampen Funds Inc. or its affiliates (collectively "Van Kampen")
for costs incurred in connection with each Portfolio's organization in the
amount of $6,828, $6,828 and $40,000, respectively per Portfolio. These costs
are being amortized on a straight line basis over the 60 month period ending
July 2, 2000, July 2, 2000 and November 4, 2002, respectively. The Adviser has
agreed that in the event any of the initial shares of the Portfolios originally
purchased by Van Kampen are redeemed during the amortization period, the
Portfolios will be reimbursed for any unamortized organizational costs in the
same proportion as the number of shares redeemed bears to the number of initial
shares held at the time of redemption.

E. FEDERAL INCOME TAXES--It is each Portfolio's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no provision for federal income taxes is required.
    Each Portfolio intends to utilize provisions of the federal income tax laws
which allow each Portfolio to carry a realized capital loss forward for eight
years following the year of the loss and offset such losses against any future
realized capital gains. The following table presents the capital loss
carryforward at December 31, 1998 along with its expiration dates. The table
also presents the identified cost of investments at June 30, 1999 for federal
income tax

    Net realized gains or losses may differ for financial reporting and tax
purposes primarily as a result of post October 31 losses which are not
recognized for tax purposes until the first day of the following fiscal year and
the deferral of losses relating to wash sale transactions.

F. DISTRIBUTION OF INCOME AND GAINS--Comstock, Emerging Growth, Enterprise,
Growth and Income, Real Estate and Strategic Stock declare dividends from net
investment income and net realized gains, if any, annually. Distributions from
net realized gains for book purposes may include short-term capital gains and
gains on option and futures transactions. All short-term capital gains and a
portion of option and futures gains are included in ordinary income for tax
purposes.
    Due to inherent differences in the recognition of income, expenses and
realized gains/losses under generally accepted accounting principles and for
federal income tax purposes, the amount of distributable net investment income
may differ between book and federal income tax purposes for a particular period.
These differences are temporary in nature, but may result in book basis
distribution in excess of net investment income for certain periods.

G. EXPENSE REDUCTIONS--During the six months ended June 30, 1999, custody fees
were reduced by the following amounts as a result of credits earned on overnight
cash balances:

5. DERIVATIVE FINANCIAL INSTRUMENTS
A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.
    The Portfolios have a variety of reasons to use derivative instruments, such
as to attempt to protect the Portfolios against possible changes in the market
value of its portfolio, manage the Portfolio's effective yield, foreign currency
exposure, maturity and duration or to generate potential gain. All of the
Portfolios' holdings, including derivative instruments, are marked to market
each day with the change in value reflected in unrealized appreciation/
depreciation. Upon disposition, a realized gain or loss is recognized
accordingly, except when taking delivery of a security underlying a futures or
forward contract. In these instances, the recognition of gain or loss is
postponed until the disposal of the security underlying the futures or forward
contract.
    Summarized below are the specific types of derivative financial instruments
used by the Portfolios.

A. FUTURES CONTRACTS--A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
fixed income Portfolios generally invest in futures on U.S. Treasury Bonds and
Notes. The equity Portfolios generally invest in S&P 500 Index Futures. Upon
entering into futures contracts, the Portfolios maintain, in a segregated
account with its custodian, cash or liquid securities with a value equal to its

obligation under the futures contracts. During the period the futures contract
is open, payments are received from or made to the broker based upon changes in
the value of the contract (the variation margin). The risk of loss associated
with a futures contract is in excess of the variation margin reflected on the
Statement of Assets and Liabilities.
    Transactions in futures contracts for Growth and Income for the six months
ended June 30, 1999, were as follows:

B. FORWARD COMMITMENTS--Real Estate may trade certain securities under the terms
of forward commitments, whereby the settlement for payment and delivery occurs
at a specified future date. Forward commitments are privately negotiated
transactions between the Portfolio and dealers. Upon executing a forward
commitment and during the period of obligation, the Portfolio maintains
collateral of cash or securities in a segregated account with its custodian in
an amount sufficient to relieve the obligation. If the intent of the Portfolio
is to accept delivery of a security traded under a forward bond purchase
commitment, the commitment is recorded as a long-term purchase. For forward bond
purchase commitments for which security settlement is not intended by the
Portfolio, changes in the value of the commitment are recognized by marking the
commitment to market on a daily basis with changes in value reflected as a
component of unrealized appreciation/depreciation. Upon the settlement of the
contract, a realized gain or loss is recognized and is included as a component
of realized gain/loss on forwards. Purchasing securities on a forward commitment
involves a risk that the market value at the time of delivery may be lower than
the agreed upon purchase price resulting in an unrealized loss. Selling
securities on a forward commitment involves different risks and can result in
losses more significant than those arising from the purchase of such securities.
During the term of the commitment, the Portfolio may sell the forward commitment
and enter into a new forward commitment, the effect of which is to extend the
settlement date. In addition, the Portfolio may occasionally close such forward
commitments prior to delivery. Risks may arise as a result of the potential
liability of the counterparties to meet the terms of their contracts. There were
no forward bond commitments outstanding as of June 30, 1999.

                         YEAR 2000 READINESS DISCLOSURE

Like other mutual funds, financial and business organizations and individuals
around the world, the Portfolios could be adversely affected if the computer
systems used by the Portfolio's investment adviser and other service providers
do not properly process and calculate date-related information and data from and
after January 1, 2000. This is commonly known as the "Year 2000 Problem." The
Portfolio's investment adviser is taking steps that it believes are reasonably
designed to address the Year 2000 Problem with respect to computer systems that
it uses and to obtain reasonable assurances that comparable steps are being
taken by the Portfolio's other major service providers. At this time, there can
be no assurances that these steps will be sufficient to avoid any adverse impact
to the Portfolio. In addition, the Year 2000 Problem may adversely affect the
markets and the issuers of securities in which the Portfolio may invest that, in
turn, may adversely affect the net asset value of the Portfolio. Improperly
functioning trading systems may result in settlement problems and liquidity
issues. In addition, corporate and governmental data processing errors may
result in production problems for individual companies or issuers and overall
economic uncertainty. Earnings of individual issuers will be affected by
remediation costs, which may be substantial and may be reported inconsistently
in U.S. and foreign financial statements. Accordingly, the Portfolio's
investments may be adversely affected. The statements above are subject to the
Year 2000 Information and Readiness Disclosure Act, which may limit the legal
rights regarding the use of such statements in the case of dispute.

                            LETTER TO POLICYHOLDERS

July 20, 1999

Dear Policyholder,
    With the volatility that we've experienced recently in many financial
markets, some investors have sold securities because of uncertainty about where
the markets were going, only to be left rethinking whether they made the right
decision. We've witnessed this kind of market activity numerous times over the
past several years, sparked by concerns such as the impact of the Asian economic
crisis, high stock valuations, or, most recently, the stability of many high-
flying technology companies. While these fears eventually subsided, investors
who may have sold during this period were unable to reap the benefits of the
subsequent rally. That's partly because most of the recent big gains happened in
relatively short periods of time. This kind of volatility--and the danger of
making short-term decisions--highlights the importance of investing for the long
term, in accordance with your individual financial objectives.
    Although the worst of the Asian crisis appears to be behind us, new concerns
are always emerging. In the coming months, we'll likely hear more about how the
year 2000 computer problem may affect the markets or that we're overdue for a
correction. While the markets could undoubtedly suffer as a result of these or
any number of other events, we encourage you to focus on your long-term
investment goals. Although nothing is certain, history has shown us that over
time, the markets tend to recover--and most investors want to be positioned to
take advantage of any recovery.
    If you have concerns about market volatility or questions about how your
portfolio is structured to respond to these events, we encourage you to contact
your financial advisor. Your advisor can talk with you about sustaining a
long-term investment plan through a variety of market conditions. We hope that
Van Kampen Funds will play an important role as you and your advisor build a
portfolio designed to help you weather what the markets have in store.

Sincerely,

                               ECONOMIC SNAPSHOT

    The strength of the domestic economy continued to defy expectations in the
first half of 1999, although it finally began to show signs of slowing down.
Strong growth, healthy employment, and low inflation all contributed to the
favorable economic environment.

STRONG ECONOMIC GROWTH
    The nation's gross domestic product rose at an impressive rate of 4.3
percent during the first quarter of 1999, but fell to 2.3 percent in the second
quarter. The first-quarter expansion was fueled by an increase in consumer
spending, which dropped to more moderate levels later in the reporting period.

POSITIVE EMPLOYMENT ENVIRONMENT
    In May, the unemployment rate dropped to 4.2 percent--its lowest level in
more than 30 years. Throughout the reporting period, unemployment remained low,
the number of jobs grew, and wages rose. The labor market remained especially
tight in the service industry and most urban areas.

LOW INFLATION
    Inflation remained low throughout most of the reporting period, although a
sharp increase in oil prices contributed to a spike in April's consumer price
index report (CPI). Following this up-tick, the Federal Reserve raised interest
rates 0.25 percent on June 30. Although the Fed had expressed a bias toward a
series of rate increases, May's tame CPI report prompted it to drop this bias
when announcing the June rate increase.

ECONOMIC OUTLOOK
    Our outlook for the economy suggests that the moderate slowdown may
continue, bringing the economy back to historically normal growth levels.
Healthy job growth, which has been supporting the consumer confidence and
spending levels, showed signs of faltering toward the end of the reporting
period. However, a renewed optimism for corporate earnings, low unemployment,
and a vibrant housing market should provide some balance against a slower job
growth rate.

(1)Total return based on net asset value (NAV) assumes an investment at the
beginning of the period indicated, reinvestment of all distributions for the
period, and sale of all shares at the end of the period, all at NAV.

Total returns do not include any charges, expenses, or fees imposed by an
insurance company at the underlying fund or separate account levels. If the
returns included the effect of these additional charges, the returns would have
been lower.

See the Comparative Performance section of the current prospectus. An investment
should be made with an understanding of the risks that an investment in equity
securities entails. These include the risk that the financial condition of the
issuers of the securities in the portfolio, or the condition of the stock market
in general, may worsen and therefore, the value of Portfolio shares may decline.
Past performance does not guarantee future results. Investment return and net
asset value will fluctuate with market conditions. Portfolio shares, when
redeemed, may be worth more or less than their original cost.

Because the prices of common stocks and other securities fluctuate, the value of
an investment in the Portfolio will vary upon the Portfolio's investment
performance. Foreign securities may magnify volatility due to changes in foreign
exchange rates, the political and economic uncertainties in foreign countries,
and the potential lack of liquidity, government supervision, and regulation.

Market forecasts provided in this report may not necessarily come to pass.

The Portfolio being offered is through a variable annuity contract.

                          PORTFOLIO MANAGEMENT REVIEW

                           ASSET ALLOCATION PORTFOLIO

The following is an interview with the portfolio management team of the Van
Kampen Life Investment Trust--Asset Allocation Portfolio. The team previously
consisted of John M. Cunniff and Walter W. Stabell III, portfolio comanagers. As
of June 1, 1999, the Portfolio has been managed by John M. Cunniff and C. Kelly
Gilbert, portfolio comanagers, and Stephen L. Boyd, chief investment officer for
equity investments.

Q     CAN YOU DESCRIBE THE STOCK AND BOND MARKET ENVIRONMENTS FOR THE PORTFOLIO
      DURING THE REPORTING PERIOD?

A     As has been its trademark recently, the stock market was volatile during
      the first six months of 1999. The Dow Jones Industrial Average passed two
      significant milestones during the reporting period--10,000 in late March
and 11,000 in early May. Investors' anticipation of an interest-rate increase
placed downward pressure on the stock market, particularly among growth stocks.
In response to this shift from growth investments, investors began to favor
cyclical stocks. The Federal Reserve did indeed raise interest rates on the last
day of the reporting period, but, because the increase was widely expected, the
effect on stock prices was limited.
    The first quarter of 1999 marked a recovery from the October 1998 meltdown
in the fixed-income market, as investors gained confidence in the strength of
the economy and modest inflation. Consequently, yield spreads narrowed between
Treasuries and other fixed-income products (such as government, corporate, and
high-yield securities). However, this good news for fixed-income products was
quelled in the second quarter by a slight surge in inflation and warnings of
interference from the Federal Reserve Board. This prompted yield spreads to
widen once again, although not to the record-high levels seen last fall.

Q     GIVEN THIS ENVIRONMENT, WHAT WAS YOUR STRATEGY IN SEEKING TO MEET THE
      PORTFOLIO'S OBJECTIVE?

A     The Portfolio seeks to provide high total return through investments in
      stocks, bonds, and money market securities. To achieve this goal, we first
      decide on an overall asset allocation based on expectations for total
returns for stocks, bonds, and cash. After deciding the asset allocation, we
invest the recommended portion of stocks of the Portfolio in large,
well-established companies with above-average growth rates. We select bonds
based on a combination of their fixed-income and capital-appreciation potential.
    During the reporting period, we reduced the Portfolio's exposure to the
equity market and added to cash and bonds. By June 30, the Portfolio's asset
allocation was approximately 43 percent stocks, 39 percent bonds, and 18 percent
cash. We made this change after consulting our asset allocation models, which
took into account a rise in both the stock market and interest rates during the
period. The Portfolio's performance did not benefit in the short term from this
asset allocation decision, although we are hopeful that this situation will help
the Portfolio's return in the long run.

Q     WHICH STOCKS IN THE PORTFOLIO PERFORMED ESPECIALLY WELL?

A     Because of the Portfolio's bottom-up approach to stock-selection, the
      performance of individual stocks can have a great impact on the
      Portfolio's overall return. For much of the reporting period, blue-chip
      stocks performed very well amid considerable market volatility. In
general, the stocks whose performance most helped the Portfolio's return were in
the technology area. The growth of the Internet and the promise of increased
business productivity fueled new purchases of technology equipment.
    Leading software-maker Microsoft continued on a path of impressive growth,
despite being involved in ongoing litigation about its business practices. The
company's stock appreciated 30 percent during the reporting period and helped
the Portfolio's performance considerably. In the financial services area,
Citigroup was also a strong contributor to the Portfolio's return, aided by the
strong recovery in the financial markets following the economic crises in the
third quarter of 1998.
    Keep in mind that not all stocks in the Portfolio performed as favorably,
and there is no guarantee that these stocks will perform as well in the future.

<PAGE>   71

Q     DID ANY STOCKS HURT THE PORTFOLIO'S RETURN?

A     Although a number of stocks failed to meet our expectations, the single
      greatest negative impact on the Portfolio's return could be found in the
      poor performance of Philip Morris. This company's stock experienced
significant pressure during the first half of 1999, as investors became
increasingly concerned about how this and other tobacco companies would respond
to various lawsuits.

Q     HOW DID YOU MANAGE THE BOND PORTION OF THE PORTFOLIO?

A     To maintain diversification, enhance liquidity, and seek to reduce risk,
      we continued to allocate the Portfolio's assets across a variety of
      sectors within the corporate bond market. We continued to focus on
      investment-grade rated securities (bonds rated BBB or higher) with
maturities of 10 to 30 years.
    The duration of the Portfolio is currently 8.05 years. This duration, which
is longer than our benchmark, reflects our belief that interest rates could
fall. Interest rates, however, rose throughout much of the period, and this was
not a favorable environment for the Portfolio. Duration is a measurement used to
quantify the sensitivity of a bond's price to changes in interest rates.
Typically, portfolios with longer durations perform better when rates are
declining, and portfolios with shorter durations perform better when interest
rates are rising.

Q     HOW DID THE PORTFOLIO PERFORM DURING THE LAST SIX MONTHS?

A     Because of the stock market's healthy performance and the rise in interest
      rates during the reporting period, the Portfolio's conservative asset
      allocation did not help relative performance. The Portfolio achieved a
      six-month total return of 1.66 percent(1) as of June 30, 1999. By
comparison, the Standard & Poor's 500 Index returned 12.36 percent, and the
Lipper Flexible Portfolio Index, which most closely resembles the Portfolio,
returned 5.73 percent. The S&P 500 Index is a broad-based, unmanaged index that
reflects the general performance of the stock market, and the Lipper Flexible
Portfolio Fund Index reflects the average performance of the 30 largest flexible
portfolio funds.
    These indices are statistical composites that do not include any commissions
or sales charges that would be paid by an investor purchasing the securities or
investments represented by these indices. Past performance is no guarantee of
future results. Please refer to the chart and footnotes on page 3 for additional
Portfolio performance results.

Q     WHAT IS YOUR OUTLOOK FOR THE PORTFOLIO FOR THE NEXT SIX MONTHS?

A     We anticipate continued market volatility. If the Fed continues to raise
      interest rates, as it did on the last day of the reporting period, we
      expect cyclical stocks to continue to outperform traditional growth
      stocks. We are also monitoring the year 2000 problem, because investors'
reaction to the situation could have an impact on the stock market's stability.
Barring major market changes, we believe that maintaining our current asset
allocation may enable us to achieve solid long-term returns.

</TABLE>

(1)Total return based on net asset value (NAV) assumes an investment at the
beginning of the period indicated, reinvestment of all distributions for the
period, and sale of all shares at the end of the period, all at NAV.

Total returns do not include any charges, expenses, or fees imposed by an
insurance company at the underlying fund or separate account levels. If the
returns included the effect of these additional charges, the returns would have
been lower.

(2)SEC Yield is a standardized calculation prescribed by the Securities and
Exchange Commission for determining the amount of net income a portfolio should
theoretically generate for the 30-day period ending June 30, 1999.

See the Comparative Performance section of the current prospectus. Past
performance does not guarantee future results. Investment return and net asset
value will fluctuate with market conditions. Portfolio shares, when redeemed,
may be worth more or less than their original cost.

Because the prices of common stocks and other securities fluctuate, the value of
an investment in the Portfolio will vary upon the Portfolio's investment
performance. Foreign securities may magnify volatility due to changes in foreign
exchange rates, the political and economic uncertainties in foreign countries,
and the potential lack of liquidity, government supervision, and regulation.

Market forecasts provided in this report may not necessarily come to pass.

The Portfolio being offered is through a variable annuity contract.

                          PORTFOLIO MANAGEMENT REVIEW

                           DOMESTIC INCOME PORTFOLIO

The following is an interview with the management team of the Van Kampen Life
Investment Trust--Domestic Income Portfolio. The team was previously led by
Walter W. Stabell III, portfolio manager, and Peter W. Hegel, chief investment
officer for fixed-income investments. As of June 1999, C. Kelly Gilbert has
replaced Mr. Stabell as portfolio manager.

Q     WHAT WERE THE MARKET CONDITIONS IN WHICH THE PORTFOLIO OPERATED DURING THE
      PAST SIX MONTHS?

A     The first quarter of 1999 marked a recovery from the October 1998 meltdown
      in the fixed-income market, as investors gained confidence in the strength
      of the economy and modest inflation. Consequently, yield spreads narrowed
between Treasuries and other fixed-income products (such as corporate,
high-yield, and government securities). However, this good news for fixed-income
products was quelled in the second quarter by a slight surge in inflation and
warnings of interference from the Federal Reserve Board. This prompted yield
spreads to widen once again, although not to the record-high levels seen last
fall.
    As interest rates climbed steadily during the period, the Treasury yield
curve began to flatten, indicating a moderation in the yield difference between
long- and short-term Treasuries. This change became more pronounced as yields on
short-term Treasuries rose to reflect the potential for an increase--or perhaps
a series of increases--in the federal funds rate. At the end of the reporting
period, the Fed approved a 0.25 percent hike while reassuring fixed-income
investors that additional action seemed unnecessary.

Q     HOW DID THE CORPORATE BOND MARKET BEHAVE DURING THIS TIME?

A     Initially, corporate bonds participated in the cautious recovery of the
      fixed-income market. However, concerns about the direction of interest
      rates imposed pressure on corporate bonds in the second quarter. For the
      six-month period, corporate bonds lagged high-yield bonds but outpaced
Treasuries.
    Thanks to the positive economic environment and relatively low interest
rates, new issuance of corporate bonds bounced back from last fall's depressed
levels, giving us a greater range of bonds to consider for purchase. While
issuance during the first half of 1999 was sharply lower than the level seen in
the first half of 1998, it remains strong by historical standards. Finance and
industry were prominent sectors among the new issuance calendar.

Q     HOW DID YOU POSITION THE PORTFOLIO IN RESPONSE TO THESE CONDITIONS?

A     To maintain diversification, enhance liquidity, and seek to reduce risk,
      we continued to allocate the Portfolio's assets across a variety of
      sectors within the corporate bond market. All sectors performed negatively
      during the period, but some fared better than others. Utilities, in which
we were overweighted, was a good defensive position for us and one of the best
performing sectors. Unfortunately, this benefit to the Portfolio was offset by
our significant weighting in industrial companies, which lagged the market's
recovery.
    Managing duration also continued to be an important tactic during the
reporting period. Duration, which is expressed in years, is a measurement of a
portfolio's price sensitivity to changes in interest rates. The longer a
portfolio's duration, the greater the effect of interest rate movements on net
asset value. Typically, portfolios with shorter durations have performed better
in a rising rate environment, while portfolios with longer durations have
performed better when rates are declining. For most of the period, the Domestic
Income Portfolio's duration was held equivalent to or slightly longer than that
of its benchmark, the Lehman Brothers Index of BBB Corporate Bonds. At present,
the Portfolio's duration is 6.4 years, which is comparable to the duration of
6.1 years for the benchmark index.

 Q    HOW DID THE PORTFOLIO PERFORM DURING THE REPORTING PERIOD?

 A   The Portfolio's return was hurt by the slow recovery of the corporate bond
      market. For the six months ended June 30, 1999, the Portfolio achieved a
      total return of -2.53 percent(1). Dividends paid and reinvested by the
Portfolio during the period totaled $0.58 per share. By comparison, the Lehman
Brothers Index of BBB Corporate Bonds produced a total return of -1.20 percent
for the same period. Keep in mind that this index is a broad-based, unmanaged
index that reflects the general performance of investment-grade corporate bonds.
This return does not reflect any commissions or fees that would be paid by an
investor purchasing the securities it represents. Of course, past performance is
no guarantee of comparable future results. Please refer to the chart and
footnotes on page 13 for additional performance results.

 Q    WHAT IS YOUR OUTLOOK FOR THE MONTHS AHEAD?

 A    We anticipate a moderate slowdown in economic growth in the months ahead,
      but do not expect this to have a negative effect on the fixed-income
      market unless it becomes a significant downturn. We believe strong
corporate bond issuance will continue over the next few months as issuers catch
up from the relatively quiet market of last fall. Because we believe the
near-term outlook for corporate bonds is good, we'll take advantage of this
issuance to add new securities to the Portfolio.
    As we manage the Portfolio going forward, our focus on fundamental, in-depth
research and assessment of corporate bonds will remain unchanged. Looking beyond
the sector, credit rating, or structure of a bond, we'll attempt to identify
those issuers that we believe will remain financially sound and perform well in
a range of market conditions. We will also look for value in out-of-favor areas
of the market in our search for opportunities to diversify the Portfolio and
contribute to its performance.

 TOTAL RETURNS

Six-month total return based on NAV(1)......................    11.61%
One-year total return based on NAV(1).......................    16.09%
Three-year average annual total return based on NAV(1)......    17.99%
Life-of-Portfolio average annual total return based on
  NAV(1)....................................................    17.31%

</TABLE>

(1) Total return based on net asset value (NAV) assumes an investment at the
beginning of the period indicated, reinvestment of all distributions for the
period, and sale of all shares at the end of the period, all at NAV.

Total returns do not include any charges, expenses, or fees imposed by an
insurance company at the underlying portfolio or separate account levels. If the
returns included the effect of these additional charges, the returns would have
been lower.

See the Comparative Performance section of the current prospectus. An investment
should be made with an understanding of the risks that an investment in equity
securities entails. These include the risk that the financial condition of the
issuers of the securities in the portfolio, or the condition of the stock market
in general, may worsen and therefore, the value of Portfolio shares may decline.
Past performance does not guarantee future results. Investment return and net
asset value will fluctuate with market conditions. Portfolio shares, when
redeemed, may be worth more or less than their original cost.

Because the prices of common stocks and other securities fluctuate, the value of
an investment in the Portfolio will vary upon the Portfolio's investment
performance. Foreign securities may magnify volatility due to changes in foreign
exchange rates, the political and economic uncertainties in foreign countries,
and the potential lack of liquidity, government supervision, and regulation.

Market forecasts provided in this report may not necessarily come to pass.

The Portfolio being offered is through a variable annuity contract.

                          PORTFOLIO MANAGEMENT REVIEW

                            GLOBAL EQUITY PORTFOLIO

The following is an interview with the management team of the Van Kampen Life
Investment Trust--Global Equity Portfolio. The Portfolio is managed by portfolio
managers Barton M. Biggs and Ann D. Thivierge, MSDW Investment Management.

 Q    HOW WOULD YOU CHARACTERIZE THE MARKET CONDITIONS IN WHICH THE PORTFOLIO
      OPERATED DURING THE PAST SIX MONTHS?

 A    Global economic recovery became the story of the first half of 1999, as
      economic activity increased in most regions of the world. The U.S. economy
      resumed its impressive climb with strong growth and minimal inflation.
Meanwhile, declining interest rates and a focus on corporate cost-cutting fiscal
reforms helped revive many emerging markets, particularly in Asia.
    In Europe, the introduction of the euro went smoothly, but economic
weakness, particularly in Germany, contributed to its decline since January.
Decreased exports to Asia, Russia, and Eastern European countries led to lower
economic growth and falling corporate earnings.

 Q    WHAT SIGNIFICANT INVESTMENT STRATEGIES AND TECHNIQUES DID YOU USE TO
      PURSUE THE PORTFOLIO'S INVESTMENT OBJECTIVE?

 A    At of the end of the reporting period, the Portfolio had the following
      regional allocations relative to six months earlier:

<S>                            <C>              <C>                  <C>
North America ...............      53.2% ....         50.6% ......       2.6%
Europe ......................      33.0% ....         37.5% ......      -4.5%
Far East ....................      11.6% ....          9.8% ......       1.8%
Other .......................       2.2% ....          2.1% ......       0.1%
</TABLE>

* As a percentage of long-term investments.

    Throughout the period, we remained underweighted in the United States
because stock valuations appeared high. This strategy hindered performance as
the U.S. economy continued its strong growth. Finally, our positions in the
peripheral European economies, including Italy, Spain, and Portugal, helped the
Portfolio's performance.
    Early in the year we visited Singapore, Hong Kong, and Japan to talk with
government officials, central bankers, businesses, and other investors. Although
these meetings reinforced our belief that Asia and Japan have a long way to go
in their recoveries, we believe their commitment to restructure their economies
could lead to a long-lasting recovery in profitability and stock prices. In
addition, we were impressed with Singapore's fervor for restructuring and belt-
tightening and, as a result, significantly increased the Portfolio's exposure to
that country.
    Another country we overweighted was Australia, which like Singapore, did a
good job of weathering the financial downturn in Asia. Australia has had
fantastic economic growth and we believe the sound government policies and
restructured labor markets should be a long-term positive.

 Q    HOW HAS THE PORTFOLIO PERFORMED DURING THE REPORTING PERIOD?

 A    Returns suffered during the past six months due to the Portfolio's
      underweight position in the United States and significant exposure to
      Europe. The Portfolio's total return during the six months ended June 30,
      1999, was 11.61 percent(1). During the same period, the Morgan Stanley
Capital International (MSCI) World Index + Dividends returned 8.69 percent.
Please keep in mind that the MSCI World + Dividends Index is a broad-based index
used as a benchmark for general global equity funds. It does not reflect any
commissions or sales charges that would be paid by

                                       23

an investor purchasing the securities it represents. Please refer to the chart
and footnotes on page 22 for additional Portfolio performance results. Past
performance does not guarantee future results.

 Q    WHAT IS YOUR OUTLOOK FOR THE MONTHS AHEAD?

 A    In the short term, we remain cautious on the United States because of high
      stock valuations and Europe because of full valuations and inconsistent
      economic performance. As a result, the risk of policy mistakes within
Europe is great, and the challenge facing the ECB will be difficult. Japan's
economy, although bottoming, faces large obstacles as unemployment rises and the
fiscal spending proposal diminishes. We are optimistic that additional
restructuring should increase corporate earnings.
    In the rest of Asia, we look for improvements in Australia and Singapore to
continue, but we will monitor China carefully. In the long-term, we believe
China will succeed, but in the short term we are unsure whether it will devalue
its currency, and the government's commitment to maintaining its unproductive
state-owned enterprise system is troubling. Overall, we have positioned the
Portfolio to be less defensive, and have reduced our cash holdings as a result.

(1)Total return based on net asset value (NAV) assumes an investment at the
beginning of the period indicated, reinvestment of all distributions for the
period, and sale of all shares at the end of the period, all at NAV.

Total returns do not include any charges, expenses, or fees imposed by an
insurance company at the underlying Portfolio or separate account levels. If the
returns included the effect of these additional charges, the returns would have
been lower.

(2)SEC Yield is a standardized calculation prescribed by the Securities and
Exchange Commission for determining the amount of net income a portfolio should
theoretically generate for the 30-day period ending June 30, 1999.

See the Comparative Performance section of the current prospectus. Past
performance does not guarantee future results. U.S. Government securities are
backed by the full faith and credit of the U.S. Government, its agencies or
instrumentalities. The government backing applies only to the timely payment of
principal and interest when due, on specific securities in the Portfolio, not to
shares of the Portfolio. Portfolio shares when redeemed, may be worth more or
less than their original cost. The value of debt securities will fluctuate with
changes in market conditions and interest rates, which will effect the value of
Portfolio shares. Securities which are issued by private issuers involve greater
risk than those issued directly by the U.S. Government.

Market forecasts provided in this report may not necessarily come to pass.

The Portfolio being offered is through a variable annuity contract.

                          PORTFOLIO MANAGEMENT REVIEW

                              GOVERNMENT PORTFOLIO

The following is an interview with the management team of the Van Kampen Life
Investment Trust--Government Portfolio. The team is led by John R. Reynoldson,
portfolio manager, and Peter W. Hegel, chief investment officer for fixed-income
investments.

 Q    HOW WOULD YOU DESCRIBE THE MARKET IN WHICH THE PORTFOLIO OPERATED DURING
      THE REPORTING PERIOD?

 A    The first quarter of 1999 marked a recovery in the fixed-income market
      from the October 1998 meltdown, as investors grew confident in the
      strength of the economy and continued modest inflation. Consequently,
      yield spreads narrowed between Treasuries and other fixed-income products
(such as government, mortgage-backed, and high-yield securities). However, this
good news for fixed-income products was quelled in the second quarter by a
slight surge in inflation and warnings of interference from the Federal Reserve
Board. This prompted yield spreads to widen once again, although not to the
record-high levels seen last fall.
     As interest rates climbed steadily during the period, the Treasury yield
curve began to flatten, indicating a moderation in the yield difference between
long- and short-term Treasuries. This change became more pronounced as yields on
short-term Treasuries rose to reflect the potential for an increase--or perhaps
a series of increases--in the federal funds rate. At the end of the reporting
period, the Fed approved a 0.25 percent hike while reassuring fixed-income
investors that additional action seemed unnecessary.

 Q    HOW DID THESE CONDITIONS AFFECT YOUR MANAGEMENT OF THE PORTFOLIO?

 A    Near the end of last year, we began increasing the Portfolio's exposure to
      mortgage-backed securities. We overweighted the portfolio with 6.5 percent
      30-year GNMAs and 6 to 6.5 percent 15-year FNMAs, because we felt these
securities had a low vulnerability to prepayment. As interest rates rose
throughout the period, the risk of prepayment and mortgage refinancing decreased
even further. At the same time, some of these issues that had been priced at a
premium--in other words, priced over par--became discounted. Although this
created some value opportunities in the mortgage market, it was detrimental to
the Portfolio's return. However, we've maintained our mortgage overweighting
because we believe the mortgage market will continue to recover from its low
point last fall.
    We also maintained the Portfolio's Treasury exposure at approximately 37
percent. Treasuries in the Portfolio were allocated in a barbell pattern, with
the heaviest weightings concentrated in long bonds and short-term Treasuries
with an average maturity of two years. As the yield curve flattened during the
period, we found that there was little value in the middle of the curve.

 Q    HOW DID THE PORTFOLIO PERFORM DURING THE REPORTING PERIOD?

 A    Challenging conditions in the mortgage market--and our high exposure to
      this area--was the most significant factor affecting the Portfolio's
      return. For the six-month period ended June 30, 1999, the Government
      Portfolio generated a total return of -3.36 percent(1). By comparison, the
Lehman Brothers Mutual Fund U.S. Government/ Mortgage Index posted a total
return of -1.14 percent for the same period. This broad-based, unmanaged index
reflects the general performance of U.S. government and mortgage-backed
securities. Please keep in mind that this index does not reflect any commissions
or fees that would be paid by an investor purchasing the securities it
represents. Of course, past performance is no guarantee of comparable future
results. For additional performance results, please refer to the chart and
footnotes on page 31.

<PAGE>   99

 Q    WHAT IS YOUR OUTLOOK FOR THE MONTHS AHEAD?

 A    We expect a continuation of the current low-inflation environment coupled
      with slower economic growth due to slight international growth and the
      possibility of year 2000 computer complications near the end of the year.
This environment supports the continued recovery of the fixed-income markets,
which are still unwinding from their upheaval late last year. Ultimately, we
believe these markets are transitioning to historically normal conditions.
Taking this perspective, we see value in the mortgage market and are comfortable
with the Portfolio's current positioning.

                          PORTFOLIO MANAGEMENT REVIEW

                             MONEY MARKET PORTFOLIO

The following is an interview with the management team of the Van Kampen Life
Investment Trust--Money Market Portfolio. The team is led by Reid J. Hill,
portfolio manager, and Peter W. Hegel, chief investment officer for fixed-
income investments.

 Q    HOW WOULD YOU CHARACTERIZE THE MARKET CONDITIONS IN WHICH THE PORTFOLIO
      HAS OPERATED DURING THE PAST SIX MONTHS?

 A    During the first quarter of 1999, the Dow Jones Industrial Average broke
      through the 10,000 point ceiling, and climbed past 11,000 points. The U.S.
      economy remained strong, leading the Fed to raise the federal funds
interest rate by 0.25 percent on June 30. Consequently, some nervous investors
fled to more stable shelter--including money market funds--near the end of the
period.

 Q    HOW DID YOU MANAGE THE PORTFOLIO IN LIGHT OF THESE CONDITIONS?

 A    We continued to pursue the Portfolio's investment objectives of capital
      protection and high current income. At the end of the period, 38.9 percent
      of the Portfolio was invested in high-grade commercial paper, 28.0 percent
in repurchase agreements ("repos"), 21.1 percent in certificates of deposits
(CDs), and 11.8 percent in government agency obligations. CDs offer a guaranteed
return of principal over a stated period of time, a fixed rate of interest, and
are typically issued by institutions whose deposits are insured.
      During the past six months, we focused on commercial paper, where we found
more value than in the bank notes sector. However, the market volatility we
experienced in late May prompted us to pursue the liquidity of repos, thus
reducing our exposure to commercial paper throughout the period.
    Within the commercial paper sector, we selected high-rated, short-term
corporate securities with ratings of at least A-1/P-1 from Moody's and Standard
& Poor's. These corporate securities provided income without assuming excessive
risk. We also favored commercial paper with an average maturity of 90 days or
less. In the current interest-rate environment, we believe there is little
benefit in extending the portfolio's risk by investing in longer-term paper,
which provides only a minimally higher return.

 Q    HOW DID THE PORTFOLIO PERFORM DURING THE SIX-MONTH REPORTING PERIOD?

 A    The Portfolio continues to provide shareholders with relative stability,
      daily liquidity at $1.00 per share, and a competitive level of current
      income. Through the six-month period ended June 30, 1999, the Portfolio
      produced a total return of 2.16 percent. As of June 30, the Portfolio
generated a seven-day average yield of 4.34 percent and a 30-day effective yield
of 4.31 percent. The Portfolio's price per share remained unchanged at $1.00
throughout the reporting period. Yield quotation more closely reflects the
current earnings of the Portfolio than the total return quotation.

 Q    WHAT IS YOUR ECONOMIC OUTLOOK FOR THE MONTHS AHEAD?

 A    As expected, the Fed raised interest rates at the end of the period, but
      surprised the market by abandoning its tightening bias and adopting a
      neutral stance on interest rates. Interest rate adjustments like these
      should not affect the Portfolio because the short-term market generally
anticipates such interventions.

    In conjunction with this outlook, we will maintain our traditional course of
investing in high-grade commercial paper, repurchase agreements, and government
obligations. At the same time, we'll look to add value through careful security
selection as we seek to achieve the Portfolio's objectives.

An investment in the Portfolio is neither insured nor guaranteed by the U.S.
government, and there can be no assurance that the Portfolio will be able to
maintain a stable net asset value of $1.00 per share.

Past performance does not guarantee future results. Investment return and net
asset value will fluctuate with market conditions. Portfolio shares, when
redeemed, may be worth more or less than their original cost.

The Portfolio being offered is through a variable annuity contract.

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Life Investment Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended, as a diversified open-end management
investment company comprised of eleven Portfolios: Asset Allocation Portfolio
("Asset Allocation"), Comstock Portfolio(1) ("Comstock"), Domestic Income
Portfolio ("Domestic Income"), Emerging Growth Portfolio(1) ("Emerging Growth"),
Enterprise Portfolio(1) ("Enterprise"), Global Equity Portfolio ("Global
Equity"), Government Portfolio ("Government"), Growth and Income Portfolio(1)
("Growth and Income"), Money Market Portfolio ("Money Market"), Morgan Stanley
Real Estate Securities Portfolio(1) ("Real Estate") and Strategic Stock
Portfolio(1) ("Strategic Stock") (collectively the "Portfolios"). Each Portfolio
is accounted for as a separate entity.

    The goals of the Portfolios are as follows: Asset Allocation seeks a high
total investment return consistent with prudent risk; Comstock seeks capital
growth and income through investments in equity securities including common and
preferred stocks and securities convertible into common and preferred stocks.
Domestic Income seeks income as its primary objective and capital appreciation
as a secondary objective; Emerging Growth seeks capital appreciation by
investing principally in common stocks of small and medium sized companies;
Enterprise seeks capital appreciation by investing principally in common stocks;
Global Equity seeks long-term growth of capital through an internationally
diversified portfolio of equity securities of any nation, including the United
States; Government seeks high current return consistent with preservation of
capital; Growth and Income seeks long-term growth of capital and income by
investing primarily in income-producing equity securities including common
stocks and convertible securities; Money Market seeks protection of capital and
high current income by investing in short-term money market instruments; Real
Estate seeks long-term growth of capital by investing principally in securities
of companies operating in the real estate industry; and Strategic Stock seeks an
above average total return consistent with the preservation of invested capital,
by investing primarily in a portfolio of dividend paying equity securities
included in the Dow Jones Industrial Average or the Morgan Stanley Capital
International USA Index.

    The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION--Investments in securities listed on a securities exchange
are valued at their sales price as of the close of such securities exchange.
Fixed income investments are valued by independent pricing services or dealers
using the mean of the bid and asked prices. Unlisted securities and listed
securities for which the last sales price is not available are valued at the
mean of the bid and asked prices. For those securities where prices or
quotations are not available, valuations are determined in accordance with
procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of 60 days or less are valued at amortized
cost. For Money Market, all investments are valued at amortized cost.

    Domestic Income's investments include lower rated and unrated debt
securities which may be more susceptible to a decline in value due to adverse
economic conditions than other investment grade holdings. These securities are
often subordinated to the prior claims of other senior lenders and uncertainties
exist as to an issuer's ability to meet principal and interest payments. Debt
securities rated below investment grade and comparable unrated securities
represented approximately 33% of Domestic Income's net assets at June 30, 1999.

                           June 30, 1999 (Unaudited)
- --------------------------------------------------------------------------------

B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Portfolios may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolios will maintain, in a segregated account with its custodian, assets
having an aggregate value at least equal to the amount of the when issued or
delayed delivery purchase commitments until payment is made.

    The Portfolios may invest in repurchase agreements which are short-term
investments in which the Portfolios acquire ownership of a debt security and the
seller agrees to repurchase the security at a future time and specified price.
The Portfolios may invest independently in repurchase agreements, or transfer
uninvested cash balances into a pooled cash account along with other investment
companies advised by Van Kampen Asset Management Inc. (the "Adviser") or its
affiliates, the daily aggregate of which is invested in repurchase agreements.
Repurchase agreements are fully collateralized by the underlying debt security.
The Portfolios will make payment for such securities only upon physical delivery
or evidence of book entry transfer to the account of the custodian bank. The
seller is required to maintain the value of the underlying security at not less
than the repurchase proceeds due the Portfolios.

C. INCOME AND EXPENSES--Dividend income is recorded on the ex-dividend date and
interest income is recorded on an accrual basis. Discounts on debt securities
purchased are amortized over the expected life of each applicable security.
Premiums on debt securities are not amortized.

D. ORGANIZATIONAL COSTS--Global Equity has reimbursed Van Kampen Funds Inc. or
its affiliates (collectively "Van Kampen") for costs incurred in connection with
the Portfolio's organization in the amount of $6,828. These costs are being
amortized on a straight line basis over the 60 month period ending July 2, 2000.
The Adviser has agreed that in the event any of the initial shares of the
Portfolio originally purchased by Van Kampen are redeemed during the
amortization period, the Portfolio will be reimbursed for any unamortized
organizational costs in the same proportion as the number of shares redeemed
bears to the number of initial shares held at the time of redemption.

E. FEDERAL INCOME TAXES--It is each Portfolio's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no provision for federal income taxes is required.

    Each Portfolio intends to utilize provisions of the federal income tax laws
which allow each Portfolio to carry a realized capital loss forward for eight
years following the year of the loss and offset such losses against any future
realized capital gains. The following table presents the capital loss
carryforward at December 31, 1998 along with its expiration dates. The table
also presents the identified cost of investments at June 30, 1999 for federal
income tax

Net unrealized appreciation/depreciation....................       (622,477)            --
</TABLE>

    Net realized gains or losses may differ for financial and tax reporting
purposes primarily as a result of post October 31 losses which are not
recognized for tax purposes until the first day of the following fiscal year and
the deferral of losses relating to wash sale transactions.

F. DISTRIBUTION OF INCOME AND GAINS--Money Market declares dividends from net
investment income and net realized gain/loss on each business day. Asset
Allocation, Domestic Income, Global Equity and Government declare dividends from
net investment income and net realized gains, if any, annually. Distributions
from net realized gains for book purposes may include short-term capital gains
and gains on option and futures transactions. All short-term capital gains and a
portion of option and futures gains are included in ordinary income for tax
purposes.

    Due to inherent differences in the recognition of income, expenses and
realized gains/losses under generally accepted accounting principles and for
federal income tax purposes, the amount of distributable net investment income
may differ between book and federal income tax purposes for a particular period.
These differences are temporary in nature, but may result in book basis
distribution in excess of net investment income for certain periods.

G. FOREIGN CURRENCY TRANSLATION--The market values of foreign securities,
forward currency exchange contracts and other assets and liabilities denominated
in a foreign currency are translated into U.S. dollars based on quoted exchange
rates as of noon Eastern Standard Time. The cost of securities is determined
using historical exchange rates. Income and expenses are translated at
prevailing exchange rates when accrued or incurred. Gains and losses on the sale
of securities are not segregated for financial reporting purposes between
amounts arising from changes in exchange rates and amounts arising from changes
in the market prices of securities. Realized gain and loss on foreign currency
includes the net realized amount from the sale of currency and the amount
realized between trade date and settlement date on security transactions.

the Adviser pays 50% of its advisory fees to the Subadviser.

    Under the terms of the advisory agreement, if the total ordinary business
expenses, exclusive of taxes, distribution fees and interest, exceed .95% of the
average daily net assets of Asset Allocation, Domestic Income, Government or

competitive benchmarks. Legal services are provided by Skadden, Arps, Slate,
Meagher & Flom (Illinois), counsel to the Portfolios, of which a trustee of the
Portfolios is an affiliated person.

    Certain officers and trustees of the Portfolios are also officers and
directors of Van Kampen. The Portfolios do not compensate their officers or
trustees who are officers of Van Kampen.

    The Portfolios provide deferred compensation and retirement plans for their
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement plan are payable for a ten-year period
and are based upon each trustee's years of service to the Trust. The maximum
annual benefit per trustee under the plan is $2,500 per portfolio.

    At June 30, 1999, Van Kampen owned 95,241 shares of Global Equity.

5. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    The Portfolios have a variety of reasons to use derivative instruments, such
as to attempt to protect the Portfolios against possible changes in the market
value of its portfolio, manage the Portfolio's effective yield, foreign currency
exposure, maturity and duration or to generate potential gain. All of the
Portfolios' holdings, including derivative instruments, are marked to market
each day with the change in value reflected in unrealized
appreciation/depreciation. Upon disposition, a realized gain or loss is
recognized accordingly, except when taking delivery of a security underlying a
futures or forward contract. In these instances, the recognition of gain or loss
is postponed until the disposal of the security underlying the futures or
forward contract.

    Summarized below are the specific types of derivative financial instruments
used by the Portfolios.

A. FUTURES CONTRACTS--A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
fixed income Portfolios generally invest in futures on U.S. Treasury Bonds and
Notes. The equity Portfolios generally invest in S&P 500 Index Futures. Upon
entering into futures contracts, the Portfolios maintain, in a segregated
account with its custodian, cash or liquid securities with a value equal to its

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

obligation under the futures contracts. During the period the futures contract
is open, payments are received from or made to the broker based upon changes in
the value of the contract (the variation margin). The risk of loss associated
with a futures contract is in excess of the variation margin reflected on the
Statement of Assets and Liabilities.
    Transactions in futures contracts for the six months ended June 30, 1999,
were as follows:

</TABLE>

B. FORWARD COMMITMENTS--Domestic Income, Global Equity, and Government may trade
certain securities under the terms of forward commitments, whereby the
settlement for payment and delivery occurs at a specified future date. Forward
commitments are privately negotiated transactions between the Portfolio and
dealers. Upon executing a forward commitment and during the period of
obligation, the Portfolio maintains collateral of cash or securities in a
segregated account with its custodian in an amount sufficient to relieve the
obligation. If the intent of the Portfolio is to accept delivery of a security
traded under a forward bond purchase commitment, the commitment is recorded as a
long-term purchase. For forward bond purchase commitments for which security
settlement is not intended by the Portfolio, changes in the value of the
commitment are recognized by marking the commitment to market on a daily basis
with changes in value reflected as a component of unrealized
appreciation/depreciation. A forward currency contract is a commitment to
purchase or sell a foreign currency at a future date at a negotiated forward
rate. Upon the settlement of the contract, a realized gain or loss is recognized
and is included as a component of realized gain/loss on forwards. Purchasing
securities on a forward commitment involves a risk that the market value at the
time of delivery may be lower than the agreed upon purchase price resulting in
an unrealized loss. Selling securities on a forward commitment involves
different risks and can result in losses more significant than those arising
from the purchase of such securities. During the term of the commitment, the
Portfolio may sell the forward commitment and enter into a new forward
commitment, the effect of which is to extend the settlement date. In addition,
the Portfolio may occasionally close such forward commitments prior to delivery.
Risks may arise as a result of the potential liability of the counterparties to
meet the terms of their contracts. The Portfolio's market exposure from these
positions is equal to the Current Value noted below.

                         YEAR 2000 READINESS DISCLOSURE

Like other mutual funds, financial and business organizations and individuals
around the world, the Portfolios could be adversely affected if the computer
systems used by the Portfolio's investment adviser and other service providers
do not properly process and calculate date-related information and data from and
after January 1, 2000. This is commonly known as the "Year 2000 Problem." The
Portfolio's investment adviser is taking steps that it believes are reasonably
designed to address the Year 2000 Problem with respect to computer systems that
it uses and to obtain reasonable assurances that comparable steps are being
taken by the Portfolio's other major service providers. At this time, there can
be no assurances that these steps will be sufficient to avoid any adverse impact
to the Portfolio. In addition, the Year 2000 Problem may adversely affect the
markets and the issuers of securities in which the Portfolio may invest that, in
turn, may adversely affect the net asset value of the Portfolio. Improperly
functioning trading systems may result in settlement problems and liquidity
issues. In addition, corporate and governmental data processing errors may
result in production problems for individual companies or issuers and overall
economic uncertainty. Earnings of individual issuers will be affected by
remediation costs, which may be substantial and may be reported inconsistently
in U.S. and foreign financial statements. Accordingly, the Portfolio's
investments may be adversely affected. The statements above are subject to the
Year 2000 Information and Readiness Disclosure Act, which may limit the legal
rights regarding the use of such statements in the case of dispute.
