HAVE THE PRINCIPLES OF INVESTING CHANGED?

        In a world of frenetic change in business, technology, and the financial
markets, it is natural to wonder whether the basic principles of investing have
changed.

        We don't think so.

        The most successful investors over the coming decade will be those who
began the new century with a fundamental understanding of risk and who had the
discipline to stick with long-term investment programs.

        Certainly, investors today confront a challenging, even unprecedented,
environment. Valuations of market indexes are at or near historic highs. The
strength and duration of the bull market in U.S. stocks have inflated people's
expectations and diminished their recognition of the market's considerable
risks. And the incredible divergence in stock returns--many technology-related
stocks gained 100% or more in 1999, yet prices fell for more than half of all
stocks--has made some investors question the idea of diversification.

        And then there is the Internet. Undeniably, it is a powerful medium for
communications and transacting business. For investors, the Internet is a vast
source of information about investments, and online trading has made it
inexpensive and convenient to trade stocks and invest in mutual funds.

        However, new tools do not guarantee good workmanship. Information is not
the same as wisdom. Indeed, much of the information, opinion, and rumor that
swirl about financial markets each day amounts to "noise" of no lasting
significance. And the fact that rapid-fire trading is easy does not make it
beneficial. Frequent trading is almost always counterproductive because
costs--even at low commission rates--and taxes detract from the returns that the
markets provide. Sadly, many investors jump into a "hot" mutual fund just in
time to see it cool off. Meanwhile, long-term fund investors are hurt by
speculative trading activity because they bear part of the costs involved in
accommodating purchases and redemptions.

        Vanguard believes that intelligent investors should resist short-term
thinking and focus instead on a few time-tested principles:

        - Invest for the long term. Pursuing your long-term investment goals is
more like a marathon than a sprint.

        - Diversify your investments with holdings in stocks, bonds, and cash
investments. Remember that, at any moment, some part of a diversified portfolio
will lag other parts, and be wary of taking on more risk by "piling onto" the
best-performing part of your holdings. Today's leader could well be tomorrow's
laggard.

        - Step back from the daily frenzy of the markets; focus on your overall
asset allocation.

        - Capture as much of the market's return as possible by minimizing costs
and taxes.

Costs and taxes diminish long-term returns while doing nothing to reduce the
risks you incur as an investor.

REPORT FROM THE CHAIRMAN

[PHOTO]
JOHN J. BRENNAN


Stock prices soared and bond prices slipped during the eventful first half of
Vanguard Variable Insurance Fund's 2000 fiscal year.

        For the six months ended March 31, 2000, the returns of our 13
portfolios ranged from an astounding 70.8% for our Small-Company Growth
Portfolio to a disappointing -6.4% for our Diversified Value Portfolio. Though
several of our portfolios registered terrific absolute gains, our overall
performance relative to our competitors was a bit lacking. Only five of our
portfolios--and just two of our eight equity funds--earned returns that topped
the results of their average peers.

        This report presents the six-month total returns (capital change plus
reinvested dividends) for our portfolios, along with the results for their
comparative standards. The total return figures reflect the change in net asset
value for each portfolio, adjusted to include the reinvestment of any income or
capital gains distributions. Performance Summaries for the portfolios, including
a breakdown of each fiscal year return into its income and capital components,
are presented on pages 21-26. The returns for the portfolios of Vanguard
Variable Insurance Fund are higher than those of the portfolios in the Vanguard
Variable Annuity Plan, which take into account the administrative and insurance
expenses associated with the plan.

THE PERIOD IN REVIEW

During the half-year ended March 31, the remarkably vibrant U.S. economy
completed its 108th month of uninterrupted expansion--a record nine full years
without a recession. For the last quarter of 1999, the economy grew at an
astounding 7.3% rate.

        This overall economic strength--and the rosy outlook it engendered among
investors--helped drive stocks higher. The U.S. stock market, as measured by the
Wilshire 5000 Total Market Index, rose an impressive 23.2% for the six months.

        However, returns were wildly disparate within the market. Small- and
mid- capitalization stocks far outpaced large-cap companies. The Wilshire 4500
Completion Index--essentially the total U.S. market minus the large-cap Standard
& Poor's 500 Index--had a total return of 42.6% for the period. And despite a
brief rally of "old economy" stocks in late March, it was the "new economy"
(i.e., technology, media, and telecommunications) stocks that dominated the
market, as they did in 1999. The growth component of the S&P 500 Index--made up
of stocks with above-average prices in relation to such measures as earnings and
book value--gained 24.7%, while the value component returned 9.2%. The
tech-heavy Nasdaq Composite Index rose 67.3% for the period.

        Meanwhile, after years of mostly nominal inflation, the cost of living
seemed to be on the rise, though much of the increase stemmed from a sharp hike
in oil prices that many analysts regarded as temporary. In March, the Consumer
Price Index was 3.7% above its level of a year earlier.

        The Federal Reserve Board--fearing that the rapidly growing economy
would spur rising prices--took action March 21, raising short-term interest
rates by 25 basis points (0.25 percentage point) for the fifth time in nine
months. The Fed's action, together with



                                       1
<PAGE>   4

the U.S. Treasury's announced plans to buy back some of its long-term debt,
caused a relatively rare "inversion of the yield curve"--a situation in which
yields of short-term debt exceed those of long-term bonds. During the six
months, the 30-year Treasury bond's yield declined 22 basis points (0.22
percentage point) to 5.83%, while the yield of a 3-month Treasury bill rose 102
basis points to 5.87%. The Lehman Brothers Aggregate Bond Index, a proxy for the
entire taxable bond market, returned 2.1% for the six months.

        International markets generally performed well, though returns among
countries and industries varied widely, as they often do. The Morgan Stanley
Capital International Europe, Australasia, Far East (EAFE) Index returned 22.5%
in local currency for the six months and 17.0% in U.S. dollars. Several markets
produced outstanding total returns during the period, including Finland (135% in
local currency), Sweden (82%), Canada (46%), and Germany (48%). Overall, the
gains around the world were led, not surprisingly, by strong advances among
technology shares, particularly telecommunications and media companies.

        A summary of the half-year results of each of our portfolios follows.
(Note: All comparative fund group returns are derived from data provided by
Lipper Inc.)

FIXED-INCOME PORTFOLIOS

Our MONEY MARKET PORTFOLIO earned a return of 2.9% during the six months,
outpacing the 2.5% return of the average money market mutual fund and the 2.6%
return of an unmanaged index of 3-month U.S. Treasury bills. As always, our
performance margin over our competitors was directly tied to our much lower
costs. Our annualized expense ratio (expenses as a percentage of average net
assets) is 0.18%, or $1.80 per $1,000 invested--just a fraction of the 0.83%, or
$8.30 per $1,000, charged by the average money market mutual fund.

the portfolio seeks to preserve the value of your investment at $1 per share, it

        Our SHORT-TERM CORPORATE PORTFOLIO returned 2.4%, topping the 1.8%
return of both our average peer and an unmanaged index of short-term securities.

        Our HIGH-GRADE BOND PORTFOLIO returned 2.3% for the half-year, ahead of
the 1.5% return of our average peer and the 2.1% gain of our benchmark, the
Lehman Aggregate Bond Index.

        During a difficult period for lower-quality bonds, our HIGH YIELD BOND
PORTFOLIO earned a total return of 0.7%-- a result that was 0.4 percentage point
behind that of its average competitor but ahead of the -0.7% return of the
Lehman High Yield Index. Generally, our portfolio invests in bonds that, while



                                       2
<PAGE>   5

they are below investment-grade, still have higher credit quality--and thus
lower credit risk--than those owned by competing funds. Over the past two years,
higher-yielding securities have suffered from lackluster demand, apparently the
result of the above-average returns generated by stocks (which have lured
investors from high-yielding bonds to equities) and concern about the safety of
lower-quality bonds.

BALANCED PORTFOLIO

Our BALANCED PORTFOLIO returned 0.9% during the six months, well below the 10.5%
return of the average balanced fund. Our return was also well behind the 11.8%
return of our unmanaged benchmark, a composite index weighted 65% in the S&P 500
Index and 35% in high-quality, long-term bonds. In both cases, our shortfall can
be traced to the relatively weak performance of value-oriented stocks, which our
fund emphasizes.

        It's important to note that the Board of Trustees recently approved a
change in the benchmark for the portfolio's bond segment, effective April 1,
2000. The change to the new benchmark--the Lehman Corporate A or Better
Index--will significantly reduce the bond segment's duration, and thus its
sensitivity to interest rate changes, and will slightly lower its credit
quality. We do not expect the shift to significantly affect the portfolio's
long-term returns; however, it will decrease the volatility of the bond holdings
and will expand the number of high-quality investment-grade bonds available to
the portfolio.

DOMESTIC EQUITY PORTFOLIOS

Our EQUITY INCOME PORTFOLIO provided a negative total return of -3.6% for the
six months, reflecting the relatively poor performance of petroleum-related
stocks and other higher-yielding issues that the portfolio emphasizes. A major
portion of our shortfall compared with our benchmarks resulted from our
avoidance of the technology sector, which includes many companies that do not
pay dividends or that pay very little. These companies, which accounted for
almost 80% of the return of the S&P 500 Index during the six months are, of
course, not candidates for inclusion in a portfolio for which income is a
primary objective.

        Our DIVERSIFIED VALUE PORTFOLIO earned the lowest return among our 13
portfolios, registering a total return of -6.4%. The fund's average competitor
earned 9.8%, while the Russell 1000 Value Index--a good measure of large value
stocks--gained 5.9%. Quite simply, several of our portfolio's stocks performed
horribly during the first five months of the period, producing a return of
-18.5%. But then our results turned around dramatically as value stocks returned
to favor. Essentially the same group of stocks advanced an amazing 15% in March
alone, helping to make up some of the earlier shortfall.

        The EQUITY INDEX PORTFOLIO booked a six-month return of 17.5%, exactly
matching the return of its target benchmark, the S&P 500 Index. Relative to
other large-cap stock mutual funds, our performance was subpar. The reason was
that the index and our portfolio held smaller stakes in the high-flying
technology sector.

        A relatively light commitment to technology shares also explained the
comparatively poor results of our MID-CAP INDEX PORTFOLIO, which earned an
excellent absolute return of 32.5% for the six months, but trailed the average
return of actively managed mid-cap mutual funds by nearly 17 percentage points.

        Large-cap growth companies continued their impressive surge during the
six months, helping to propel our GROWTH PORTFOLIO to an advance of 26.6%. Here
too, however, a return that is impressive in absolute terms was disappointing
when compared with the results of similar funds. We fell 11 percentage points
short of the average large-cap growth fund's return and 7.5 percentage points
short of the return of the Russell 1000 Growth Index, a good measure of the
types of stocks that our portfolio emphasizes. As with the Mid-Cap Index
Portfolio, our return suffered from a lighter commitment to some of the
fastest-growing--and most speculative--technology companies.

        Our SMALL COMPANY GROWTH PORTFOLIO earned the highest return among our
13 portfolios, recording a stunning six-month gain of 70.8%. Our terrific return
(the equivalent of about six years worth of average stock-market gains) resulted
from the nearly unprecedented performance of tech stocks and health-care--mainly
biotech--issues. The portfolio's tech stocks, which made up about 30% of its
assets, soared 178% during the six months, and its health-care stocks (about 25%
of assets) climbed 170%. Our average peer also benefited from the tech advances,
returning 65.4% for the period.

        Our REIT INDEX PORTFOLIO earned a six-month return of 1.9%, right in
line with other real-estate funds and our target index. REIT funds fell victim
to a combination of two factors: higher interest rates, which can inflict a
double-whammy of higher borrowing costs and increased investment competition
from bonds; and a slightly higher supply of REIT issues, which lowered prices.

INTERNATIONAL PORTFOLIO

Our INTERNATIONAL PORTFOLIO earned a terrific six-month return of 29.2%, ahead
of the 17.0% return of the Morgan Stanley Capital International Europe,
Australasia, Far East (EAFE) Index, and the 27.0% return of the average
international fund.



                                       4
<PAGE>   7

On March 31, one of the fund's largest commitments to a single country was its
nearly 20% stake in Japan, where stocks gained 12% in yen and 17% in U.S.
dollars. (For U.S. investors, a strong dollar diminishes the returns from
international investments while a weaker dollar augments international returns.)
Overall, our portfolio benefited from its solid exposure to technology, media,
and telecommunications companies.

IN SUMMARY

In the first two weeks of April, just after the end of this reporting period,
U.S. technology stocks plummeted and their returns slipped into negative
territory for the calendar year, while value stocks registered modest gains.
This episode served to show how quickly and unpredictably market sectors can
move into and out of favor.

        Because the financial markets are ever-unpredictable, we advocate the
time-tested strategy of diversification and investing for the long run. Holding
well-diversified stock funds, as well as bond and money market funds, gives you
exposure to the major asset classes and can help you to maintain your balance in
turbulent times. We urge investors to base their investment program on their own
goals, time horizon, and risk tolerance--and to stick with their plan over the
long haul.

        For their part, the low-cost portfolios of Vanguard Variable Insurance
Fund can help investors diversify their holdings while taking advantage of the
tax benefits available through a variable annuity or variable life insurance
plan.

NOTICE TO SHAREHOLDERS

CHANGE IN BENCHMARK FOR SMALL COMPANY GROWTH PORTFOLIO

The Board of Trustees of Vanguard Variable Insurance Fund has approved a change
in the investment benchmark for the Small Company Growth Portfolio. On June
30, 2000, the portfolio's benchmark will change from the Small Company Growth
Fund Stock Index to the Russell 2000 Growth Index. The new benchmark will be
cited in fund reports to help investors evaluate our relative performance, and
it will help determine the compensation paid to the portfolio's investment
adviser, Granahan Investment Management, Inc. Because the two indexes'
characteristics are broadly similar, the change will have no effect on the
portfolio's composition, investment policies, strategies, or risk level.

THE REASON FOR THE CHANGE

The Small Company Growth Fund Stock Index, which has been the portfolio's
benchmark since late 1997, is made up of the stocks held by the 25 largest
small- capitalization mutual funds. (The index is adjusted annually according
to Lipper Inc.'s classification of small-cap funds.) While this index has been
a suitable benchmark for the Small Company Growth Portfolio, the Russell 2000
Growth Index is equally suitable and is a more widely recognized measure of
the performance of small-cap growth stocks. The Trustees believe that the
Russell index will be easier for investors to understand and follow.

AMENDING THE ADVISORY CONTRACT

Compensation for the portfolio's investment adviser, Granahan Investment
Management, Inc., is tied to the portfolio's performance relative to that of
its unmanaged index benchmark. Accordingly, the fund's advisory contract will
be amended to adopt the new benchmark for determining compensation after June
30, 2000. All other terms of the advisory contract will remain the same.

THE MARKETS IN PERSPECTIVE
SIX MONTHS ENDED MARCH 31, 2000







A strong economy and an extraordinary run-up in prices for technology stocks
carried broad market indexes higher during a volatile but generally rewarding
six months ended March 31, 2000.

        The rise in stocks was surprising in light of higher inflation and
rising interest rates, both of which did some damage to bond prices. For stock
investors, however, worries about inflation and interest rates did little to
dampen enthusiasm for technology, telecommunications, and media companies.

        The U.S. economy continued its rapid growth during the semiannual
period. Gross domestic product, an estimate of total economic output, increased
at a 7.3% pace, even after inflation, during the final three months of 1999. The
economy expanded by more than 4% during 1999, which is a brisk clip for a large
economy, especially one that in March completed a record 108 consecutive months
without a recession.

*Annualized.

        Inflation measures sent mixed messages. Higher oil prices did cause the
Consumer Price Index to increase by 1.9% and 3.7% for the six- and twelve-month
periods ended March 31. But if energy and food prices were factored out,
inflation remained tame. Nonetheless, the Federal Reserve Board, concerned that
rapid growth and low unemployment (around 4% of the workforce) would cause
inflation to build momentum, continued the efforts it began in June 1999 to slow
the economy. The Fed raised its target for short-term interest rates by 0.25
percentage point on three occasions during the six months, bringing the federal
funds rate to 6.0%.

U.S. STOCK MARKETS

The technology sector continued to dominate the stock market during the
half-year, although it suffered some setbacks. Over a five-week period from
March 10 through April 14, technology stocks fell sharply and the Nasdaq
Composite Index, which is dominated by large tech issues, declined -34%.
However, for the six months ended March 31, the Nasdaq Composite registered an
incredible 67.3% return.

        The overall stock market, as measured by the Wilshire 5000 Index, posted
a 23.2% gain. Large-capitalization stocks didn't do quite as well--the S&P 500
Index returned 17.5%. The small-cap Russell 2000 Index gained 26.8%.





                                       7

<PAGE>   10


        Computer software and hardware companies, semiconductor makers, and an
array of Internet-related companies powered the advance on Wall Street. Indeed,
one-third of the 57 companies in the S&P 500's tech group gained more than 100%
during the six months. A number of tech-related companies within the
producer-durables and utility groups also posted impressive gains. For the
half-year, technology stocks, which accounted for one-quarter of the total
market capitalization of the S&P 500 Index, gained 53%. Producer-durables
companies returned 36%. The oil-drilling and services companies in the "other
energy" category benefited from higher oil prices and returned about 30% for the
six months.

        Despite the impressive gains for the market averages, many individual
stocks declined. The market's worst-performing sectors were consumer staples
(-14%), including large food, beverage, supermarket, and tobacco stocks, and
the materials & processing group (-6%), which was hurt by higher energy prices,
competitive pressure from imports, and higher interest rates.

        With demand for stocks high, Wall Street came up with new supply: During
the first three months of 2000, a record $75 billion in new stock was issued
through underwriters.

U.S. BOND MARKETS

The step-by-step increases in short-term interest rates by the Federal Reserve
did succeed in elevating other short-term rates. For example, yields of 3-month
U.S. Treasury bills rose by 102 basis points (about 1 percentage point) during
the half-year, from 4.85% on September 30 to 5.87% on March 31. Yields on 3-year
Treasury notes rose about 75 basis points, in line with the Fed's actions.

        But for long-term Treasury bonds, interest rates fell during the period.
This was due primarily to the federal government's budget surplus, which
resulted in reduced issuance of new bonds and steps by the Treasury to buy back
some of its existing long-term securities. This reduced supply of long-term
bonds caused the yield on the 30-year Treasury to fall 22 basis points--from
6.05% to 5.83%--during the half-year. Yields of 10-year Treasury securities rose
only 12 basis points to 6.00% as of March 31.

        Higher short-term rates and lower or relatively stable long-term rates
resulted in an inversion in the yield curve. Instead of the usual upward sloping
curve--with yields rising along with the maturity of Treasury securities--yields
were lower for long-term bonds.

        Outside of the Treasury market, yields rose and prices fell for most
intermediate-to long-term corporate and municipal bonds. The overall bond
market, as measured by the Lehman Aggregate Bond Index, posted a 2.1% return, as
an average price decline of -1.3% offset much of the 3.4% income provided by
the market.

INTERNATIONAL STOCK MARKETS

Stock markets in Europe, Asia, and many emerging markets produced double-digit
gains during the half-year as investors responded to improving global economic
growth and a rise in corporate merger and acquisition activity. The overall
return from developed foreign markets was an excellent 17.0%, as measured by the
Morgan Stanley Capital International Europe, Australasia, Far East (EAFE) Index.

        In Europe, an average return of 27.7% in local-currency terms was
reduced to 17.6% for U.S. investors because of the U.S. dollar's gains against
European currencies. (Returns from abroad are diminished when the dollar rises
in value against other currencies, and increased when the dollar falls.) Stocks
in the Pacific region, which is dominated by Japan, returned 15.6% in dollars
and 12.8% in local-currency terms. The Select Emerging Markets Free Index soared
26.2% in dollars, led by big gains in Turkey (111%) and Brazil (60%).

REPORT FROM VANGUARD FIXED INCOME GROUP
MONEY MARKET, SHORT-TERM CORPORATE,
AND HIGH-GRADE BOND PORTFOLIOS





During the first half of our fiscal year, the Federal Reserve raised its target
for the federal funds rate--the rate banks charge each other for overnight
loans--by a total of 0.75 percentage point. In the marketplace, short-term rates
rose further--generally by more than 1 percentage point--reflecting expectations
that the Fed would raise interest rates again. Long-term rates did not rise as
much, and for U.S. Treasury securities, yields actually inverted: When the
semiannual period ended on March 31, 2000, longer-term interest rates were lower
than those on short-term issues.

        Between June 30, 1999, and the end of our fiscal half-year, the Fed
raised interest rates five times for a total of 1.25 percentage points. The
first three reductions reversed cuts that the Fed had made in autumn 1998 to
increase liquidity in the markets, which were reacting to deteriorating
financial conditions in Asia and Russia. The two most recent increases reflect
the Fed's concern that demand for goods and services is outstripping the
available supply, which could cause inflation to worsen. Fed Chairman Alan
Greenspan has repeatedly identified the rise in stock prices as one source of
excess demand in the economy. He has said that the "wealth effect" from the bull
market is fueling an unsustainable pace of demand and has implied that the Fed
will continue to tighten monetary policy until demand moderates.

        Critics of the Fed's rate boosts have pointed to recent economic reports
suggesting that core measures of inflation remain subdued. However, officials
can identify a wide array of economic statistics to bolster their argument that
demand is growing too fast. Ordinarily, the effect of higher interest rates is
most evident in such interest-rate-sensitive sectors as housing and autos. But
so far, the effect on the housing market has been muted: Single-family housing
starts are down only slightly from their pace in 1999 and are at high levels by
past standards. So far in 2000, auto sales have been occurring at an annual rate
of more than 18 million units, so there's little evidence of slowing due to
higher interest rates.

        Growth in total economic output--the inflation-adjusted gross domestic
product--spurted to a 7.3% annual rate in the fourth quarter of 1999, reflecting
an insatiable appetite for goods and services by consumers. This high demand has
left employers scrambling for the means to satisfy it. Initial claims for
unemployment insurance keep trending lower, indicating that the pool of
available workers is shallow--a potentially difficult problem for employers.
There have been some


                                       9
<PAGE>   12

signs of upward pressure on wages, although unit-labor-cost increases have
remained relatively low because of gains in productivity.

        Adding to the difficulty of the Fed's effort to slow the economy is that
long-term interest rates, in particular those that affect the housing market,
have declined recently. Corporate bond yields have been relatively stable, but
have come down a bit from their recent peaks. Without more evidence that
economic momentum is weakening, officials at the Fed are likely to further
tighten monetary policy.

MONEY MARKET PORTFOLIO

Rising short-term rates were a boon to the Money Market Portfolio, which
returned 2.9% during the first half of fiscal 2000. This brought the portfolio's
twelve-month return to 5.4%. In managing the portfolio, we have kept its average
maturity somewhat shorter than usual so that its return will more quickly
reflect changes in interest rates. This stance is based on our view that the Fed
is likely to raise interest rates again. As in the past, we purchase only
high-quality securities, and we maintain one of the lowest expense ratios in the
industry. The combination allows us to outperform the vast majority of our
competitors while remaining conservative in terms of the superior credit quality
of our holdings.

SHORT-TERM CORPORATE PORTFOLIO

The 2.4% return of the Short-Term Corporate Portfolio during the semiannual
period surpassed the 1.8% total return for both our average mutual fund
competitor and our index benchmark.

        Over the last six months, bond investors have been paid a substantial
yield premium relative to Treasuries for assuming the higher credit risk of
corporate securities. In part, this higher premium has stemmed from the
anticipation that continuing federal budget surpluses will permit the government
to substantially reduce--or eventually even to eliminate--the Treasury debt held
in the market. However, even after allowing for this factor, we believed that
yields for corporate securities were attractive in light of our positive outlook
for the economy and corporate earnings. Therefore, to maximize the portfolio's
income, we focused our buying on debt from issuers with A and BBB credit
ratings. As with every security we purchase, our team of credit analysts made an
independent assessment of each issuer's ongoing creditworthiness.

        Because we expect the Fed to keep raising interest rates, we reduced the
average maturity of the portfolio's holdings, thus reducing its price
sensitivity to changes in rates. This tactical decision cushioned the effect of
higher rates on the portfolio's share price during the fiscal half-year and
helped us to outperform our comparative benchmarks.

HIGH-GRADE BOND PORTFOLIO

As we noted above, interest rates have risen in the overall bond market, except
for long-term U.S. Treasury bonds. Yields on shorter-term Treasury
securities--with maturities ranging from 3 months to 2 years--rose by 1 to 1.1
percentage points during the half-year, largely in response to the Fed's rate
increases. However, for longer-term Treasuries, the Fed's efforts have been
blunted somewhat by the federal budget surplus, which has reduced issuance and
prompted the Treasury to begin repurchasing some long-term bonds. Yields on
10-year Treasury securities rose by less than 0.15 percentage point, and the
yield of the 30-year Treasury bond declined by 0.22 percentage point.

        The adjacent table shows how various sectors of the Lehman Aggregate
Bond Index performed recently. Government bonds were the best-performing
category by a significant margin over the last six months, and by a smaller
margin for the twelve-month period. The relative strength of these securities is
due to concern about both their relative scarcity and the possible impact of
further interest rate increases by the Fed.

        The High-Grade Bond Portfolio aims to closely track the performance of
the Lehman Aggregate Bond Index. We're pleased that the portfolio has done a bit
better than that for both the six-month and twelve-month periods ended March 31.
For the half-year, the portfolio returned 2.34% versus 2.08% for the index; for
the full year, the respective results were 1.95% and 1.87%. Given that the
portfolio has operating and transaction costs that the theoretical index does
not incur, the portfolio's performance before costs exceeded the index returns
by about 0.5 percentage point in each period.

        As of March 31, the portfolio's assets were allocated 24% to government
bonds, 36% to corporate bonds, 6% to dollar-denominated foreign bonds, and 34%
to mortgage-backed securities.

INVESTMENT PHILOSOPHY

MONEY MARKET PORTFOLIO

The adviser believes a portfolio can provide the highest level of current income
consistent with capital preservation and liquidity by holding high-quality money
market instruments issued by financial institutions, nonfinancial corporations,
and the U.S. government.

SHORT-TERM CORPORATE PORTFOLIO

The adviser believes a portfolio can provide relatively high levels of current
income with only modest share-price fluctuation by holding high-quality
corporate bonds with short- and intermediate-term maturities.

HIGH-GRADE BOND PORTFOLIO

The adviser believes a portfolio can provide sustainable, high levels of current
income by holding an extremely well-diversified group of U.S. government,
corporate, and mortgage-backed bonds that parallels the performance of the
Lehman Brothers Aggregate Bond Index.

REPORT FROM WELLINGTON
MANAGEMENT COMPANY, LLP
HIGH YIELD BOND PORTFOLIO





The High Yield Bond Portfolio returned a disappointing 0.7% and -1.1%,
respectively, for the six- and twelve-month periods ended March 31, 2000.

        The past year has been a generally difficult period for bonds. The yield
on 10-year U.S. Treasury bonds rose only 12 basis points (0.12 percentage point)
between September 30 and March 31, but it has increased 76 basis points since a
year ago. As we have stated often, the direction of interest rates doesn't
necessarily determine how high-yield bonds behave. Trends in the market for
these below-investment-grade issues are difficult to anticipate. Under some
conditions, high-yield bonds follow the direction of the stock market. At other
times--typically when both the stock and bond markets are reasonably
stable--high-yield bonds tend to behave like other bonds. And sometimes the
high-yield market does not take its cue from either of the other major capital
markets. This is what we've witnessed very recently.

        In 1998, investment-grade bond prices rose while yields declined, yet
high-yield bonds labored. Over the last twelve months, stocks soared, and
high-yield bonds struggled. However, total returns on high-yield issues were
only slightly negative, even though interest rates on intermediate-term bonds
have risen noticeably and a record $23 billion worth of high-yield bonds
defaulted in 1999 ($5 billion more than the record set in 1991). The large
yields available in the below-investment-grade market sheltered it against very
negative forces. Also, the vibrant domestic economy and the bullish stock market
softened the blow of rising interest rates and defaults.

        With the Federal Reserve raising short-term interest rates--and thus
implicitly restricting credit--the high-yield market could be fighting a
headwind for another six months. When credit is rationed, the marginal borrower
or lower-rated issuer must pay higher interest rates to obtain credit. We have
begun to see this phenomenon. Investors will decrease their tolerance for risk
if the economy's growth rate begins to slow, as the Fed apparently would prefer.

        We remain very selective with respect to credit quality, and we exercise
in-depth research on every company whose securities we consider. To decrease
risk, we diversify holdings by purchasing securities from a number of issuers in
different industries. We are avoiding smaller, start-up companies. We continue
to emphasize the higher-quality spectrum of the below-investment-grade market,
focusing on cash-paying issues rated "B" or better. We do not hold preferred
stocks or debt from emerging markets.

Earl E. McEvoy, Senior Vice President and
Portfolio Manager

April 12, 2000

INVESTMENT PHILOSOPHY

The adviser believes a diversified group of high-yielding, medium- and
low-quality corporate bonds--selected after rigorous credit assessment--can
provide sustainable, high current income as well as some potential for capital
growth.

REPORT FROM WELLINGTON
MANAGEMENT COMPANY, LLP
BALANCED PORTFOLIO





During the six months ended March 31, the Balanced Portfolio returned 0.9%.
The equity portion of the portfolio, which at the end of March was about
two-thirds of assets, returned 0.6%, well behind the 17.5% gain of the S&P 500
Index. Through the first five months of the period, most of the stock market's
gains were made by securities in the technology sector. On average, other
sectors were essentially flat. The Balanced Portfolio continues to emphasize
companies that have low price/earnings ratios and dividend yields above the
market's average. As a result, we have only modest representation in the tech
sector, where valuations are quite high and few stocks pay dividends. The
portfolio's bond sector, which accounted for nearly one-third of assets on March
31, returned 1.6% during the six months.

       We acknowledge that our "value" approach to investing has not been in
favor in the last two years. But we are confident that investors' interest in
high-quality securities that sell at relatively low valuations will return in
the future. Economic conditions are improving in many areas of the world,
especially in Asia after the financial crises of 1998. This bodes well for
market sectors in which the portfolio has meaningful exposure, such as basic
materials, industrial, and energy. We also maintain large exposure to
transportation, finance, and health-care stocks.

        Among the stocks added to the portfolio during the half-year were
Gillette and Raytheon. Both of these stocks came under pressure as a result of
earnings disappointments that we think are temporary.

        U.S. Treasury bond prices have been held up--and yields held down--by
investors' realization that the growing federal budget surplus will result in a
shrinking supply of government debt securities. As a result, corporate bonds
have lagged Treasuries during most of the semiannual period. This was
surprising, given that the U.S. economy has been quite strong and corporate bond
issuers are generally in good financial health. Transaction activity in the bond
portion of the fund has focused recently on reducing the average duration in
line with the new bond benchmark, the Lehman Corporate A or Better Index.

        We are disappointed about the fund's six-month return, and we certainly
expect better results going forward. We hope that the extreme valuations in the
technology sector will be corrected without a serious impact on the overall
market. In March, the market's behavior in this respect was quite encouraging.

Portfolio Manager
Paul D. Kaplan, Senior Vice President and

INVESTMENT PHILOSOPHY

The adviser believes that a reasonable level of current income and long-term
growth in capital can be achieved without undue risk by holding 60% to 70% of
assets in common stocks and the balance in fixed-income securities. Consistent
with this approach, dividend-paying stocks dominate the equity segment of the
portfolio, while long-term, high-quality corporate, U.S. Treasury, and
mortgage-backed securities make up the bond segment.

REPORT FROM NEWELL ASSOCIATES
EQUITY INCOME PORTFOLIO



During the first six months of the Equity Income Portfolio's 2000 fiscal year,
the world of common stocks split in two: the old world of companies governed by
traditional rules of valuation and the new world of technology companies driven
by euphoric expectations and stock-price momentum. The new-world stocks were
caught up in an ebullient bull market while the old-world stocks were caught in
the quicksand of an old-fashioned bear market. The technology-heavy Nasdaq
Composite Index rose a stunning 67% in the period, while the Equity Income
Portfolio returned -3.6%.

        These new-world stocks seem to be turning up everywhere. Even many of
the supposedly conservative, yield-seeking funds that make up Lipper Inc.'s
equity income category now include a healthy dose of tech stocks. For example,
funds in the category hold an average of 9% of their assets in technology, with
some holding 36% in tech. The presence of these stocks explains the group's 3.0%
return for the fiscal half-year.

        Many observers believe that much of the huge divergence in performance
among segments of the equity markets has been caused by the widespread movement
of money from traditional value investments to much more aggressive offerings.
Those who manage value-oriented investments have been forced to sell stocks that
they believe are cheap, driving prices down on stocks that have already low
expectations. On the other hand, those who manage more aggressive portfolios are
forced to buy popular, fast-growing stocks in order to keep up with the crowd,
even though they may believe that these stocks are ridiculously expensive.

        This process considerably heightens the risk attached to the popular
technology and Internet stocks. The reality is that few of these favorites will
be able to earn enough money to justify their high price/earnings ratios. For
large companies, out-of-line P/E ratios are usually corrected by large price
declines. In the early 1970s, a group of "one-decision" stocks known as the
Nifty Fifty soared in price, sending P/E ratios to unprecedented levels. In the
two-year decline that followed, the prices of these stocks dropped an average of
55%, and they took an average of nine years to recover.

        After a nearly 20-year run of rising stock prices--a stretch that has
produced record-high valuations--selling the stocks of safe and sane companies
to buy into the riskiest market sectors is exactly the opposite of what
conservative investors should be doing. In the bear market of 1973-1974,
investors learned that there was no such thing as a one-decision stock. We
believe that investors will eventually realize that there is only one investment
world. In the end, the rules of valuation for new-world and old-world companies
will have to come together, as they finally did for the Nifty Fifty.

Roger D. Newell, Chairman

April 12, 2000

INVESTMENT PHILOSOPHY

The adviser believes that a portfolio made up of undervalued stocks, whose
dividend yields are high both in relation to current market averages and to
historical norms, can provide a high level of current income, the potential for
capital appreciation, and below-average price volatility for a stock mutual
fund.

REPORT FROM BARROW, HANLEY,
MEWHINNEY & STRAUSS, INC.
DIVERSIFIED VALUE PORTFOLIO



As the U.S. economy enters its record tenth year of expansion, there is good
reason to be optimistic: Signs of an imminent recession are absent, inflation
remains reasonably low, and corporate profits for the first quarter of 2000 are
estimated to be 18% higher than for the same quarter last year. On the negative
side, the Federal Reserve has raised interest rates five times since last June
and is likely to do so again when it meets on May 16. While rates on longer-term
U.S. Treasury bonds have fallen by roughly 25 basis points (in part because of
shrinking supply) during the past six months, shorter-term rates have risen by
more than 100 basis points. Moreover, the spread between yields on
investment-grade corporate bonds and yields on Treasuries is the widest it has
been since the "Asian contagion" crisis in fall 1998.

        During the January-March quarter, the negative impact of rising interest
rates more than offset the favorable profits outlook, and stocks were generally
flat to down. Exceptions were the utilities sector (which did well because of
its defensive qualities) and the technology sector (which was widely perceived
as impervious to an economic slowdown). Because the Nasdaq Composite Index is
dominated by technology stocks, it was up about 15% through February, even as
the broad market declined. But midway through March, a powerful shift in the
market sent the Nasdaq plummeting and the S&P 500 Index--and value-oriented
stocks in particular--soaring.

        In this climate, your portfolio had a disappointing six months and
returned -6.4%. In our letter six months ago, we talked about how painful the
market's focus on growth stocks had been for value investors. Our relative
returns had been quite poor, as the market in 1999 favored only those issues
that seemed to promise high growth. However, this mindset seems to have changed
dramatically. Stocks that achieved prices that were silly have retreated. Some
of these companies will never make a profit and are down 60%-90%, on the way to
becoming worthless. At the same time, value stocks have risen. As of this
writing, your fund is up for the calendar year, and significantly ahead of the
S&P 500 and other indexes, so we feel more credible in challenging the premise
that "value is dead--buy growth at any price."

        The financial media love simplistic characterizations that make good
sound bites but don't necessarily depict the real world. The current distinction
between the "old economy" and the "new economy" is a perfect example, with the
former class of companies assumed to be like buggy-whip manufacturers early in
the automobile age. It's a false analogy. Although most of the companies we
currently invest in would not be called "new economy" stocks, virtually every
one is very much involved in using technology and telecommunications
breakthroughs to increase sales opportunities and to lower costs.

        We are confident that this portfolio will be resistant to declines and
has significant upside potential.

James P. Barrow

April 12, 2000

INVESTMENT PHILOSOPHY

The adviser believes that superior long-term investment results can be achieved

above-average dividend yields, below-average prices in relation to earnings,

REPORT FROM LINCOLN CAPITAL
MANAGEMENT COMPANY
GROWTH PORTFOLIO





In each of the past two fiscal years, your Growth Portfolio's return was very
high (over 20%) in the first half and slightly negative in the second half. The
first half of the present fiscal year generated a 26.6% return. It would be nice
if, for a change, the six months ahead were positive as well!

        A return of nearly 27% for just six months is extraordinary.
Nevertheless, some large-cap growth benchmarks generated even higher returns.
The Russell 1000 Growth Index and many mutual funds in the large-cap growth
category have a significant sprinkling of mid-cap technology issues, which were
red-hot during the half-year. We fell about 7 to 10 percentage points short of
these benchmarks. Our return did exceed that of the S&P 500/BARRA Growth Index
and, thanks to a strong growth tailwind, we outpaced the S&P 500 Index by 9.1
percentage points.

        When a portfolio posts a high return, you're certain to find some big
winners. Our five largest winners, all tech stocks, generated about three-fifths
of the portfolio's return: Cisco Systems, Nokia, Intel, EMC, and Applied
Materials. Yes, we had some losers: Procter & Gamble and its earnings shortfall
cost the portfolio just over 1 percentage point.

        In comparison with the Russell 1000 Growth Index, the portfolio's tech
holdings lagged by 3 percentage points, and our communications stocks lagged by
about 2 points. Lincoln normally does not heavily overweight or underweight
industry sectors in comparison with growth indexes. For example, on March 31
technology stocks, as we categorize them, constituted 51% of the portfolio and
about 46% of the Russell 1000 Growth Index. Except for cyclical growth
companies, a group that includes the mega-cap General Electric, no other sector
has a weight over 10%. Reflecting the dramatic transformation that
technology-related stocks have wrought in the market, the Growth Portfolio's
tech-sector weighting has nearly doubled in the past year. Eight of the
portfolio's ten largest holdings are technology stocks. The others are General
Electric and Warner-Lambert (which is being acquired by Pfizer). Three of the
tech stocks are new to the top ten: America Online, Texas Instruments, and Sun
Microsystems.

        As noted in our letter six months ago, Lincoln has responded to the
market's extraordinary changes by adding an experienced telecommunications
analyst to its staff. We also are planning to add another tech-stock researcher
and have moved from two analysts to one in the consumer nondurables area. Stock
markets both at home and abroad are being transformed by the surge in technology
innovation and a powerful desire by investors to participate. We believe we have
responded appropriately by repositioning the portfolio, by adapting our
investment process, and by expanding our investment coverage. We will continue
to provide whatever resources are necessary to do the job for you.

INVESTMENT PHILOSOPHY

The adviser believes that superior long-term investment results can be achieved
by emphasizing investments in high-quality, established growth companies whose
stocks sell at reasonable prices considering their expected earnings and
compared to values in the broad stock market.

REPORT FROM GRANAHAN INVESTMENT
MANAGEMENT, INC.
SMALL COMPANY GROWTH PORTFOLIO



The Small Company Growth Portfolio gained 70.8% for the six months ended March
31, 2000, well above the returns for both our index benchmark and the average
small-capitalization growth fund.

        A renewal of interest in small companies with high growth potential
began in earnest during the second half of calendar 1999, although this interest
was narrowly focused on technology and biotechnology stocks. Internet
infrastructure-building drove up many technology stocks, and progress in
biotechnology, especially the prospect of sequencing the human genome,
heightened interest in this group.

        As we noted in our last report, technology and health care are two
important sectors in our portfolio. Together, they represented 47% of assets at
the start of the current fiscal year. During the six months ended March 31, nine
of our top 15 performers were technology companies and six were in health care.
The former included SeaChange (video-on-demand servers and software),
MicroStrategy (marketing software), Macrovision (software copy protection), and
Exchange Applications (marketing software). Among the latter were Medarex
(pharmaceuticals), PE Celera (genomic mapping), and Abgenix (antibody research).

        Other important contributors to performance included AstroPower
(photovoltaic electric power), Learning Tree (information-technology training),
and Mettler-Toledo (scales and analytical instruments).

        Holdings that hurt our relative performance included Adaptive Broadband
(wireless communications), BSQUARE (software and services for intelligent
computing devices), Isis Pharmaceuticals, and Insight Communications (cable
company).

        Near the end of the half-year, the market drew back from the stocks that
had been leading the way, and this is continuing as we write. After valuations
rose to exceptionally high levels during the period, we reduced our holdings in
many stocks from the technology and health-care groups. At the peak, these two
sectors represented 55% of the portfolio, but by March 31, we had cut their
combined weighting to about 42%.

        We increased our sector weightings in energy and financial-services
stocks and are looking to do the same in consumer stocks. We raised some cash in
the process of adjusting our holdings, and as of March 31 we had about 15% of
the portfolio's assets in cash investments, providing flexibility to accumulate
stocks at more reasonable prices. Stocks new to the portfolio during the
half-year included Core Labs and Hanover Compressor in energy; the brokerages
Dain Rauscher and Jefferies; and Clayton Homes (manufactured housing), Regis
(hair salons), and ValueVision (TV home shopping) in the consumer group. We see
some interesting opportunities in the trucking area, because higher fuel costs
and driver shortages have reduced stock prices in this group to attractive
levels.

       Companies we hold are showing earnings acceleration, from a growth rate
of about 15% last September to about 32% currently. We believe the portfolio's
emphasis on companies with high potential for earnings growth positions it well
for the long term.

INVESTMENT PHILOSOPHY

The adviser believes that superior long-term investment results can be achieved
by emphasizing stocks of small and emerging companies (market capitalizations of
up to $1 billion) with favorable prospects for price appreciation. While most of
the companies have records of growth and strong market positions, the portfolio
also invests in companies that are pioneering new technologies or appear to be
undervalued.

REPORT FROM SCHRODER INVESTMENT
MANAGEMENT NORTH AMERICA INC.
INTERNATIONAL PORTFOLIO



The International Portfolio returned 29.2% during the six months ended March 31,
2000. This was ahead of the 17.0% return of the MSCI EAFE Index and the average
return of 27.0% for international stock mutual funds.

        The portfolio's exposure to technology, media, and telecommunications
companies--the market's hottest sectors--has been the most important factor in
its performance over the past six months. This is in contrast to the usual
pattern, whereby country exposures have been the most important. Overall, about
43% of the portfolio's investments are in these three sectors: 23% in
technology, 5% in media, and 15% in telecommunications. The EAFE Index has about
32% in the same industries.

        The performance of these sectors is being driven by dramatic
technological advances rather than by macroeconomic factors. However, it is
encouraging to note that macroeconomic factors are also supportive of non-U.S.
stock prices at this point. That should help if the "new economy" stocks falter.

        Continental Europe is in the sweet spot of the economic cycle. Growth
has broadened to encompass all the major countries. In addition, corporations
are restructuring aggressively, and hostile takeover bids are becoming a feature
of a region that historically had shunned them. About 43% of the portfolio is
invested in Continental Europe, and the outlook seems encouraging.

        Some 18% of the portfolio is invested in Japan. We recently have
increased the spread of our holdings there, which had been focused on a small
number of world-class companies. Thanks to another massive wave of government
spending, economic growth in Japan may broaden to domestic companies and rise to
1.5% this year. An expanding economy is the best backdrop for pushing through
the reforms that are desperately needed, but neither the government nor Japanese
companies generally show much real enthusiasm for change. Accordingly, despite
having a more positive near-term view, I remain cautious for the outlook after
this year. Most of our Japanese yen exposure is currently hedged back to U.S.
dollars.

        The portfolio has 19% of assets invested in the United Kingdom. Nearly
one-quarter of this is represented by Vodafone, resulting from its successful
bid for Mannesmann. The remainder is invested predominantly in mid-sized
companies that represent outstanding value.

        Finally, 16% of the portfolio is invested in the smaller Asian countries
and in Latin America. The former are tremendous beneficiaries of global economic
growth and, particularly, of demand for high-tech products. Most of our holdings
are exporting companies that should prosper if world trade remains buoyant this
year, as we expect. Latin America depends on foreign


                                       19
<PAGE>   22

capital inflows, and our 3% stake there reflects a balance between risk and a
positive near-term outlook.

        As I write, markets are volatile. Despite its bias toward "new economy"
companies, the portfolio is diversified. However, there is only modest
protection in the portfolio against a major market swing back to value stocks.

INVESTMENT PHILOSOPHY

The adviser believes that an international stock portfolio can achieve superior
long-term investment results by holding the stocks of non-U.S. companies with
the potential for above-average earnings growth. Particular emphasis is placed
on companies in countries with favorable business and market environments.

AVERAGE COUPON. The average interest rate paid on the securities held by a
portfolio. It is expressed as a percentage of face value.

AVERAGE DURATION. An estimate of how much a bond portfolio's share price will
fluctuate in response to a change in interest rates. To see how the price could
shift, multiply the portfolio's duration by the change in rates. If interest
rates rise by one percentage point, the share price of a portfolio with an
average duration of five years would decline by about 5%. If rates decrease by a
percentage point, the portfolio's share price would rise by 5%.

AVERAGE MATURITY. The average length of time until bonds held by a portfolio
reach maturity (or are called) and are repaid. In general, the longer the
average maturity, the more a portfolio's share price will fluctuate in response
to changes in market interest rates.

AVERAGE QUALITY. An indicator of credit risk, this figure is the average of the
ratings assigned to a portfolio's securities holdings by credit-rating agencies.
The agencies make their judgment after appraising an issuer's ability to meet
its obligations. Quality is graded on a scale, with Aaa or AAA indicating the
most creditworthy bond issuers and A-1 or MIG-1 indicating the most creditworthy
issuers of money market securities. U.S. Treasury securities are considered to
have the highest credit quality.

BETA. A measure of the magnitude of a portfolio's past share-price fluctuations
in relation to the ups and downs of the overall market (or appropriate market
index). The market (or index) is assigned a beta of 1.00, so a portfolio with a
beta of 1.20 would have seen its share price rise or fall by 12% when the
overall market rose or fell by 10%.

CASH RESERVES. The percentage of a portfolio's net assets invested in "cash
equivalents"--highly liquid, short-term, interest-bearing instruments. This
figure does not include cash invested in futures contracts to simulate stock or
bond investment.



                                       27
<PAGE>   30

COUNTRY DIVERSIFICATION. The percentages of a portfolio's common stock invested
in securities of various countries.

DISTRIBUTION BY CREDIT QUALITY. This breakdown of a portfolio's securities by
credit rating can help in gauging the risk that returns could be affected by
defaults or other credit problems.

DISTRIBUTION BY ISSUER. A breakdown of a portfolio's holdings by type of issuer
or type of instrument.

DISTRIBUTION BY MATURITY. An indicator of interest-rate risk. In general, the
higher the concentration of longer-maturity issues, the more a portfolio's share
price will fluctuate in response to changes in interest rates.

EARNINGS GROWTH RATE. The average annual rate of growth in earnings over the
past five years for the stocks now in a portfolio.

EXPENSE RATIO. The percentage of a portfolio's average net assets used to pay
its annual administrative and advisory expenses. These expenses directly reduce
returns to investors.

FOREIGN HOLDINGS. The percentage of a portfolio's equity assets represented by
stocks or American Depositary Receipts of companies based outside the United
States.

INVESTMENT FOCUS. This grid indicates the focus of a portfolio in terms of two
attributes. For equity portfolios, the attributes are market capitalization
(large, medium, or small) and relative valuation (growth, value, or a blend).
For fixed-income portfolios, the attributes are average maturity (short, medium,
or long) and average credit quality (Treasury/agency, investment-grade
corporate, or below investment-grade).

MEDIAN MARKET CAP. An indicator of the size of companies in which a portfolio
invests; the midpoint of market capitalization (market price x shares
outstanding) of a portfolio's stocks, weighted by the proportion of the
portfolio's assets invested in each stock. Stocks representing half of the
portfolio's assets have market capitalizations above the median, and the rest
are below it.

PORTFOLIO ASSET ALLOCATION. This chart shows the proportions of a portfolio's
holdings allocated to different types of assets.

PRICE/BOOK RATIO. The share price of a stock divided by its net worth, or book
value, per share. For a portfolio, the weighted average price/book ratio of the
stocks it holds.

PRICE/EARNINGS RATIO. The ratio of a stock's current price to its per-share
earnings over the past year. For a portfolio, the weighted average P/E of the
stocks it holds. P/E is an indicator of market expectations about corporate
prospects; the higher the P/E, the greater the expectations for a company's
future growth.

R-SQUARED. A measure of how much of a portfolio's past returns can be explained
by the returns from the overall market (or its benchmark index). If a
portfolio's total return were precisely synchronized with the overall market's
return, its R-squared would be 1.00. If a portfolio's returns bore no
relationship to the market's returns, its R-squared would be 0.

RETURN ON EQUITY. The annual average rate of return generated by a company
during the past five years for each dollar of shareholder's equity (net income
divided by shareholder's equity). For a portfolio, the weighted average return
on equity for the companies whose stocks it holds.

SECTOR DIVERSIFICATION. The percentages of a portfolio's common stocks that come
from each of the major industry groups that compose the stock market.

TURNOVER RATE. An indication of trading activity during the period. Portfolios
with high turnover rates incur higher transaction costs and are more likely to
distribute capital gains (which are taxable to investors).

YIELD. A snapshot of a portfolio's income from interest and dividends. The
yield, expressed as a percentage of the portfolio's net asset value, is based on
income earned over the past 30 days (7 days for money market portfolios) and is
annualized, or projected forward for the coming year.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how each portfolio's total net assets changed during the
two most recent reporting periods. The Operations section summarizes information
detailed in the Statement of Operations. Because the Money Market, Short-Term
Coporate, High-Grade Bond, and High Yield Bond Portfolios distribute their
income to shareholders each day, the amounts of Distributions--Net Investment
Income generally equal the net income earned as shown under the Operations
section. The other portfolios' amounts of Distributions--Net Investment Income,
and all portfolios' amounts of Distributions--Realized Capital Gain, may not
match the amounts shown in the Operations section, because distributions are
determined on a tax basis and may be made in a period different from the one in
which the income was earned or the gains were realized on the financial
statements. The Capital Share Transactions section shows the amount shareholders
invested in the portfolio, either by purchasing shares or by reinvesting
distributions, as well as the amounts redeemed. The corresponding numbers of
Shares Issued and Redeemed are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table summarizes each portfolio's investment results and distributions to
shareholders on a per-share basis. It also presents the portfolio's Total Return
and shows net investment income and expenses as percentages of average net
assets. These data will help you assess: the variability of the portfolio's net
income and total returns from year to year; the relative contributions of net
income and capital gains to the portfolio's total return; and how much it costs
to operate the portfolio. The table also shows the Portfolio Turnover Rate, a
measure of trading activity. A turnover rate of 100% means that the average
security is held in the portfolio for one year. Money market portfolios are not
required to report a Portfolio Turnover Rate.

NOTES TO FINANCIAL STATEMENTS

Vanguard Variable Insurance Fund is registered under the Investment Company Act
of 1940 as a diversified open-end investment company and comprises the Money
Market, Short-Term Corporate, High-Grade Bond, High Yield Bond, Balanced, Equity
Income, Diversified Value, Equity Index, Mid-Cap Index, Growth, Small Company
Growth, International, and REIT Index Portfolios. Each portfolio's shares are
only available for purchase by separate accounts of insurance companies as
investments for variable annuity plans or variable life insurance contracts.

       Certain investments of the Money Market, Short-Term Corporate, High-Grade
Bond, High Yield Bond, and Balanced Portfolios are in corporate debt
instruments; the issuers' abilities to meet their obligations may be affected by
economic developments in their respective industries. The International
Portfolio invests in securities of foreign issuers, which may subject the
portfolio to investment risks not normally associated with investing in
securities of U.S. corporations.

A. The following significant accounting policies conform to generally accepted
accounting principles for mutual funds. The fund consistently follows such
policies in preparing its financial statements.

       1. SECURITY VALUATION: Money Market Portfolio: Investment securities are
valued at amortized cost, which approximates market value. Other portfolios:
Equity securities are valued at the latest quoted sales prices as of the close
of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on
the valuation date; such securities not traded on the valuation date are valued
at the mean of the latest quoted bid and asked prices. Prices are taken from the
primary market in which each security trades. Bonds, and temporary cash
investments acquired over 60 days to maturity, are valued using the latest bid
prices or using valuations based on a matrix system (which considers such
factors as security prices, yields, maturities, and ratings), both as furnished
by independent pricing services. Other temporary cash investments are valued at
amortized cost, which approximates market value. Securities for which market
quotations are not readily available are valued by methods deemed by the Board
of Trustees to represent fair value.

       2. FOREIGN CURRENCY: Securities and other assets and liabilities
denominated in foreign currencies are translated into U.S. dollars at the
exchange rates on the valuation date as employed by Morgan Stanley Capital
International in the calculation of its indexes.

       Realized gains (losses) and unrealized appreciation (depreciation) on
investment securities include the effects of changes in exchange rates since the
securities were purchased, combined with the effects of changes in security
prices. Fluctuations in the value of other assets and liabilities resulting from
changes in exchange rates are recorded as unrealized foreign currency gains
(losses) until the asset or liability is settled in cash, when they are recorded
as realized foreign currency gains (losses).

       3. FUTURES AND FORWARD CURRENCY CONTRACTS: The Equity Index and Mid-Cap
Index Portfolios use S&P 500 Index and S&P MidCap 400 Index futures contracts,
respectively, to a limited extent, with the objectives of maintaining full
exposure to the stock market, enhancing returns, maintaining liquidity, and
minimizing transaction costs. The portfolios may purchase futures contracts to
immediately invest incoming cash in the market, or sell futures in response to
cash outflows, thereby simulating a fully invested position in the underlying
index while maintaining a cash balance for liquidity. The portfolios may seek to
enhance returns by using futures contracts instead of the underlying securities
when futures are believed to be priced more attractively than the underlying
securities. The primary risks associated with the use of futures contracts are
imperfect correlation between changes in market values of stocks held by the
portfolios and the prices of futures contracts, and the possibility of an
illiquid market.

      The Short-Term Corporate Portfolio may use Municipal Bond Index, U.S.
Treasury Bond, and U.S. Treasury Note futures contracts, with the objectives of
enhancing returns, managing interest-rate risk, maintaining liquidity,
diversifying credit risk, and minimizing transaction costs. The portfolio may
purchase or sell futures contracts instead of bonds to take advantage of pricing
differentials between the futures contracts and the underlying bonds. The
portfolios may also seek to take advantage of price differences among bond
market sectors by simultaneously buying futures

                                       61
<PAGE>   64

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(or bonds) of one market sector and selling futures (or bonds) of another
sector. Futures contracts may also be used to simulate a fully invested position
in the underlying bonds while maintaining a cash balance for liquidity. The
primary risks associated with the use of futures contracts are imperfect
correlation between changes in market values of bonds held by the portfolio and
the prices of futures contracts, and the possibility of an illiquid market.

       The International Portfolio enters into forward currency contracts to
protect the value of securities and related receivables and payables against
changes in foreign exchange rates. The portfolio's risks in using these
contracts include movement in the values of the foreign currencies relative to
the U.S. dollar and the ability of the counterparties to fulfill their
obligations under the contracts.

       Futures and forward currency contracts are valued at their quoted daily
settlement prices. The aggregate principal amounts of the contracts are not
recorded in the financial statements. Fluctuations in the value of the contracts
are recorded in the Statement of Net Assets as an asset (liability) and in the
Statement of Operations as unrealized appreciation (depreciation) until the
contracts are closed, when they are recorded as realized gains (losses) on
futures or forward currency contracts.

       4. FEDERAL INCOME TAXES: Each portfolio intends to continue to qualify as
a regulated investment company and distribute all of its taxable income.
Accordingly, no provision for federal income taxes is required in the financial
statements.

       5. REPURCHASE AGREEMENTS: The Money Market Portfolio may invest in
repurchase agreements secured by U.S. government obligations. The other
portfolios, along with other members of The Vanguard Group, transfer uninvested
cash balances to a Pooled Cash Account, which is invested in repurchase
agreements secured by U.S. government securities.

       Securities pledged as collateral for repurchase agreements are held by a
custodian bank until the agreements mature. Each agreement requires that the
market value of the collateral be sufficient to cover payments of interest and
principal; however, in the event of default or bankruptcy by the other party to
the agreement, retention of the collateral may be subject to legal proceedings.

       6. DISTRIBUTIONS: Distributions of net investment income to shareholders
of the Money Market, Short-Term Corporate, High-Grade Bond, and High Yield Bond
Portfolios are declared daily and paid on the first business day of the
following month. Annual distributions of net investment income to shareholders
of the Balanced, Equity Income, Diversified Value, Equity Index, Mid-Cap Index,
Growth, Small Company Growth, International, and REIT Index Portfolios are
recorded on the ex-dividend date. Annual distributions from realized capital
gains, if any, are recorded on the ex-dividend date.

       7. OTHER: Dividend income is recorded on the ex-dividend date. The REIT
Index Portfolio's dividend income is recorded at management's estimate of the
income included in distributions received from the REIT investments.
Distributions received in excess of this estimated amount are recorded as a
reduction of the cost of investments. The actual amounts of income and return of
capital are only determined by each REIT after its fiscal year-end, and may
differ from the estimated amounts. Security transactions are accounted for on
the date the securities are bought or sold. Costs used to determine realized
gains (losses) on the sale of investment securities are those of the specific
securities sold. Premiums and discounts on debt securities purchased are
amortized and accreted, respectively, to interest income over the lives of the
securities.

B. The Vanguard Group furnishes investment advisory services to the Money
Market, Short-Term Corporate, High-Grade Bond, Equity Index, Mid-Cap Index, and
REIT Index Portfolios on an at-cost basis.

       Wellington Management Company, llp; Newell Associates; and Lincoln
Capital Management Company provide investment advisory services to the High
Yield Bond, Equity Income, and Growth Portfolios, respectively. For the six
months ended March 31, 2000, the investment advisory fees of the High Yield
Bond, Equity Income, and Growth Portfolios represented effective annual rates of
0.06%, 0.10%, and 0.15%, respectively, of average net assets.

Malaysian securities purchased after February 14, 1999, are subject to a 10%
levy on realized gains upon sale and conversion of proceeds from Malaysian
ringgits to another currency. At March 31, 2000, the International Portfolio had
recorded a liability (included in unrealized foreign currency losses) of
$28,000, representing the levy that would be assessed if all subject Malaysian
holdings were sold at their current values and the proceeds repatriated.

       The International Portfolio had net unrealized foreign currency losses of
$30,000 resulting from the translation of other assets and liabilities at March
31, 2000.

are required to be secured at all times by collateral at least equal to the
market value of securities loaned; however, in the event of default or
bankruptcy by the other party to the agreement, retention of the collateral may
be subject to legal proceedings.

VANGUARD VARIABLE INSURANCE FUND

STATEMENT OF NET ASSETS  -  MARCH 31, 2000 (UNAUDITED)

The Statement of Net Assets should be read in conjunction with the Statement of
Operations, Statement of Changes in Net Assets, Financial Highlights, and Notes
to Financial Statements, all of which appear in the accompanying report.

       This Statement provides a detailed list of each portfolio's holdings,
including each security's market value on the last day of the reporting period.
Securities are grouped and subtotaled by asset type (common stocks, U.S.
government and agency issues, corporate bonds, etc.) and by industry sector or,
for international securities, by country. (The Equity Index and Mid-Cap Index
Portfolios' securities are listed in descending market value order.) Other
assets are added to, and liabilities are subtracted from, the value of Total
Investments to calculate the portfolio's Net Assets. Finally, Net Assets are
divided by the outstanding shares of the portfolio to arrive at its share price,
or Net Asset Value (NAV) Per Share. The NAV is the price used for portfolio
share transactions with separate accounts of insurance companies, and differs
from the accumulated value of units in their variable annuity plans or variable
life insurance contracts.

       At the end of the Statement of Net Assets, you will find a table
displaying the composition of the portfolio's net assets on both a dollar and
per-share basis. Because all income and any realized gains must be distributed
to shareholders each year, the bulk of net assets consists of Paid in Capital
(money invested by shareholders). The amounts shown for Undistributed Net
Investment Income and Accumulated Net Realized Gains usually approximate the
sums the portfolio had available to distribute to shareholders as income
dividends or capital gains as of the statement date; portfolios that distribute
net income to shareholders as a dividend each day usually have no Undistributed
Net Investment Income. Any Accumulated Net Realized Losses, and any cumulative
excess of distributions over net income or net realized gains, will appear as
negative balances. Unrealized Appreciation (Depreciation) is the difference
between the market value of the portfolio's investments and their cost, and
reflects the gains (losses) that would be realized if the portfolio were to sell
all of its investments at their statement-date values.
