FELLOW SHAREHOLDERS:

    Two roads diverged in a wood, and I--I took the one less traveled by, and
that has made all the difference.

    I can think of no better words than those of Robert Frost to begin this
special letter to our shareholders, who have placed such extraordinary trust in
me and in Vanguard over the past quarter century. When the firm was founded 25
years ago, we deliberately took a new road to managing a mutual fund enterprise.
Instead of having the funds controlled by an outside management company with its
own financial interests, the Vanguard funds--there were only 11 of them
then--would be controlled by their own shareholders and operate solely in their
financial interests. The outcome of our unprecedented decision was by no means
certain. We described it then as "The Vanguard Experiment."

    Well, I guess it's fair to say it's an experiment no more. During the past
25 years, the assets we hold in stewardship for investors have grown from $1
billion to more than $500 billion, and I believe that our reputation for
integrity, fair-dealing, and sound investment principles is second to none in
this industry. Our staggering growth--which I never sought--has come in
important part as a result of the simple investment ideas and basic human values
that are the foundation of my personal philosophy. I have every confidence that
they will long endure at Vanguard, for they are the right ideas and right
values, unshakable and eternal.

    While Emerson believed that "an institution is the lengthened shadow of one
man," Vanguard today is far greater than any individual. The Vanguard crew has
splendidly implemented and enthusiastically supported our founding ideas and
values, and deserves the credit for a vital role in forging our success over the
years. It is a dedicated crew of fine human beings, working together in an
organization that is well prepared to press on regardless long after I am gone.
Creating and leading this enterprise has been an exhilarating run. Through it
all, I've taken the kudos and the blows alike, enjoying every moment to the
fullest, and even getting a second chance at life with a heart transplant four
years ago. What more could a man ask?

    While I shall no longer be serving on the Vanguard Board, I want to assure
you that I will remain vigorous and active in a newly created Vanguard unit,
researching the financial markets, writing, and speaking. I'll continue to focus
whatever intellectual power and ethical strength I possess on my mission to
assure that mutual fund investors everywhere receive a fair shake. In the spirit
of Robert Frost:

    But I have promises to keep, and miles to go before I sleep, and miles to go
before I sleep.

    You have given me your loyalty and friendship over these long years, and I
deeply appreciate your thousands of letters of support. For my part, I will
continue to keep an eagle eye on your interests, for you deserve no less. May
God bless you all, always.

/s/ JCB

REPORT FROM THE CHAIRMAN

JOHN J. BRENNAN

    The overall U.S. stock market posted solid gains during the 12 months ended
January 31, 2000, the fiscal year for the Vanguard Specialized Funds. However,
results varied widely for various market sectors during the period, a fact that
was reflected in the returns for the five funds. These ranged from a -1.0%
decline for the REIT Index Fund to a 25.8% advance for the Energy Fund. The
table at right presents the 12-month total returns (capital change plus
reinvested dividends) of each fund, along with those of its comparative fund
group and a relevant unmanaged index. It also presents the return of the
Standard & Poor's 500 Index, which represents about 80% of the market value of
U.S. stocks.

    Details on each fund, including per-share net asset values, income
dividends, and any capital gains distributions, appear in the table that
follows this letter.

FINANCIAL MARKETS IN REVIEW

    The U.S. economic expansion tied an all-time endurance record and stock
prices rose during the 12 months ended January 31. The Wilshire 5000 Total
Market Index, which tracks the entire U.S. market, posted a 14.4% return, led
by a surge in technology stocks (the tech-heavy Nasdaq Composite Index gained
58.8%).

    Big mergers were in vogue around the world, touching nearly every market
sector. Among the pairings: Consolidated Edison took over Northeast Utilities
(electric utilities); MCI WorldCom won a bidding battle for Sprint
(long-distance phone service); Exxon acquired Mobil (oil); and Glaxo Wellcome
and SmithKline Beecham agreed to a merger (pharmaceuticals). Among media
companies, Internet service provider America Online took over Time Warner. In
wireless communications, Vodafone AirTouch won a long battle to acquire
Mannesmann.

    The stock market's advance was surprising, given the weakness of bonds
during fiscal 2000. Bond prices fell as interest rates rose sharply. Yields of
10-year U.S. Treasury notes rose more than 2 percentage points, and the
benchmark 30-year Treasury bond's yield increased 1.4 percentage points to
6.49%. The overall bond market, as measured by the Lehman Brothers Aggregate
Bond Index, recorded a total return of -1.9%.

FISCAL 2000 PERFORMANCE OVERVIEW

Four of the five Vanguard Specialized Funds posted positive returns during the
12 months. The Energy Fund and the Gold and Precious Metals Fund enjoyed strong
gains of 25.8% and 17.5%, respectively. The Health Care Fund's 10.6% return was
in line with that of the large-capitalization-dominated Standard & Poor's 500
Index. The Utilities Income Fund managed only a small positive return (2.8%),
while the REIT Index Fund posted a -1.0% decline, for its second consecutive
down year. A detailed look at each fund's performance during fiscal 2000 and
over the longer term follows.

HEALTH CARE FUND

Health-care stocks had a weak first half but revived during the second half of
our fiscal year. Vanguard Health Care Fund posted a 12-month total return of
10.6%--its seventh consecutive fiscal year of positive returns. Your fund
topped the S&P 500 Index by 0.3 percentage point and was well ahead of the
- -2.9% return of the S&P Health Sector Index, although it lagged the 29.0%
average return for health/biotechnology funds.

    It was a disappointing year for the stocks of most large pharmaceutical and
managed-care companies. There was one very bright spot in the health-care
group--biotechnology stocks soared, with a number of individual issues doubling
in price during the 12-month period. The Health Care Fund held a number of
biotech stocks--including Immunex, a developer of genetically engineered drugs,
which soared 152% in the last three months of 1999--but had a smaller stake in
the group than a number of competing funds. Our investment adviser, Wellington
Management Company, LLP, maintains a relatively conservative, diversified
portfolio. As of January 31, the fund held more than 130 stocks, including
major pharmaceutical firms, specialty pharmaceutical companies,
medical-products providers, health-services providers, and international
health-care concerns. About 9% of total assets were in cash investments at our
fiscal year-end.

- ---------------------------------------------------------------------------
</TABLE>


    Being diversified within the sector has worked well over the long haul for
the Health Care Fund. As the table below shows, our average annual return
during the past decade was 22.6%, or 1.5 percentage points better, on average,
than the return posted by the average peer fund. We achieved this result with
less volatility, too, thanks to our more diversified character. A $10,000
investment made ten years ago in our fund would have grown to $76,462, assuming
the reinvestment of all dividends and capital gains distributions. This was
nearly $8,500 more than would have resulted from an identical investment in the
average fund in our peer group, an advantage equal to roughly 85% of the
initial investment.

    Our fine record stems from both the skill of our adviser and the head start
provided year after year by our lower operating costs. The fund's expense ratio
in fiscal 2000 amounted to 0.41%, or $4.10 per $1,000 of assets, one-fourth the
expense ratio of 1.67%, or $16.70 per $1,000, charged by the average
health/biotechnology fund. In any given year, of

                                       2
<PAGE>   5

course, factors such as concentration in a particular sector or fortuitous
stock-picking can overwhelm the effects of low operating costs. But over the
long run, it is extremely difficult to overcome an annual cost differential of
1 percentage point or more.

    As you know, the Board of Trustees closed the Health Care Fund to new
investors between February and December. We took the step--and two related
measures--to avert large cash inflows, which followed the fund's stunning
performance in 1998 and threatened to crimp our adviser's investment approach.
The cooling of the sector in 1999 dampened the fervor over health-care stocks,
enabling us to reopen the fund. Its new $10,000 minimum initial investment
requirement for nonretirement accounts and the extension of the 1% redemption
fee to shares held less than five years (for shares purchased on or after April
19, 1999) should also serve long-term investors well.

ENERGY FUND

Vanguard Energy Fund had a robust total return of 25.8% during the fiscal year,
a rebound from the steep decline it suffered the previous year. The average
natural resources fund did even better, gaining 31.2%. Both your fund and its
average peer far outdistanced the return of the S&P 500 Index, which includes
stocks from every economic sector. The return of the Energy Fund, however, fell
just short of that of the S&P Energy Sector Index.

    Sharp increases in prices for oil and natural gas pumped up shares in
energy companies during the 12 months, boosting your fund's performance. Crude
oil prices more than doubled--from less than $12 per barrel to nearly $30--due
to increased demand from an expanding global economy and production cutbacks by
oil-producing nations. Prices for natural gas increased more than 40%.

    The Energy Fund lagged its average competitor mainly because it held a
larger share of assets in domestic integrated-oil companies. Stocks of these
large firms--which participate in every stage of the business, from exploration
and drilling to refining and marketing--did well, but not as well as those of
oil-services firms. As of January 31, the fund had roughly one-quarter of its
assets in domestic integrated-oil companies, with the remainder in providers of
energy equipment and services, exploration companies, refining and marketing
companies, and foreign energy stocks.

    Over the past decade, Vanguard Energy Fund has performed much better than
its average peer, although the entire group has trailed the broad stock market.
The table at right presents the average annual returns of our fund, the average
natural resources fund, the S&P Energy Sector Index, and the S&P 500 Index for
the decade ended January 31. It also shows the final value of hypothetical
$10,000 investments made ten years ago in each, assuming the reinvestment of
dividends and capital gains distributions.

- -------------------------------------------------------------------------
</TABLE>


    As you can see, the Energy Fund topped the return for its peer group by an
average of 3.2 percentage points annually during the decade. This advantage
amounted to more than $6,200, or 62% of the initial investment. However, the
S&P 500 Index, which is broadly diversified, earned a return twice as high.

                                       3
<PAGE>   6

    Roughly one-third of the Energy Fund's advantage over its average
competitor was due to our low operating costs. For the past fiscal year, our
expense ratio (operating costs as a percentage of average net assets) was
0.48%, or $4.80 per $1,000 invested. This was less than one-third the expense
ratio of 1.68%, or $16.80 per $1,000 invested, charged by the average natural
resources fund.

REIT INDEX FUND

Vanguard REIT Index Fund had a total return of -1.0% during the 12 months ended
January 31. The decline was disappointing, especially in light of the broad
stock market's double-digit gain. Your fund's return was in line, however, with
the -1.2% return of its unmanaged benchmark, the Morgan Stanley Real Estate
Investment Trust Index, and it outpaced the average real estate fund by 1.3
percentage points.

    Prices for real estate investment trusts enjoyed a springtime rally, which
apparently stemmed from news of an investment in REITs by Berkshire Hathaway,
the insurance and investment company led by legendary investor Warren E.
Buffett. But on the whole, it was a frustrating year for real estate stocks.
Although REITs offer a high level of current income, most investors were
focused on fast-growing companies, especially those engaged in technology and
wireless telephony. In addition, the rise in interest rates over the course of
the year hurt REITs in two ways. First, higher yields on bonds provide
increased competition for high-yielding stocks. Second, higher rates result in
higher operating costs for REITs with variable-rate debt. Finally, despite weak
demand for REITs during the period, there was a modest increase in their
supply, which put downward pressure on prices.

    Since its inception in May 1996, Vanguard REIT Index Fund has provided an
average annual return of 6.2%. Though this result badly trailed the overall
stock market, it was 0.5 percentage point higher than the return of the average
real estate fund, and 0.3 point better than the return of the unmanaged Morgan
Stanley REIT Index.

    While we cannot predict the total returns of REITs, we believe that they
will continue to offer an attractive level of current income. For its part,
Vanguard REIT Index Fund will at all times provide investors with broad
exposure to commercial real estate at low cost. In fiscal 2000, the fund's
expense ratio was 0.33%, or $3.30 per $1,000 of assets, less than one-quarter
the average expense ratio of 1.51%, or $15.10 per $1,000 of assets, charged by
competing REIT funds.

UTILITIES INCOME FUND

Vanguard Utilities Income Fund returned 2.8% in fiscal 2000, trailing the
return of the Utilities Composite Index--an unmanaged benchmark that reflects
your fund's 85% stock/15% bond target asset allocation--by 0.5 percentage
point.

    Our customarily heavy weighting in electric utilities--about half of the
fund's equity assets were invested in the group during the year--was a key
factor in our shortfall versus the average utility fund, which returned 17.1%.
Electric companies as a group declined by more than 10%. Another factor was
that we did not hold a number of

                                       4

<PAGE>   7




strong-performing stocks in companies connected with wireless
telecommunications and Internet access. Many of these stocks were off-limits to
the fund because they pay little or no dividends and thus aren't in keeping
with our objective of providing a relatively high level of current income.

    A third factor in our shortfall versus our peers stemmed from the fund's
bond component, which had a total return of -5.3% during the fiscal year. This
decline was due to rising interest rates, which depress the prices of existing
bonds. Our stake in bonds--which averaged about 10% of net assets--was roughly
twice as large as that of the average utility fund. As of January 31, the
fund's current annualized yield was 3.1%, the same as one year earlier. The
Utilities Income Fund's asset allocation remained fairly constant during the
fiscal year. At year-end, the fund had approximately 87% in stocks, 9% in
bonds, and 4% in short-term reserves.

 Telephone Index, and 15% Lehman Utility Bond Index thereafter.


    Within the U.S. utilities industry, deregulation and market forces have led
to a gradual shift of corporate emphasis toward growth--and away from
dividends. In light of this trend, we have modified the fund's investment
guidelines, effective April 1, 2000, to allow the adviser, Wellington
Management Company, to invest up to 25% of the fund's assets in stocks of
foreign-based utility companies. In general, international utility companies
exhibit a strong commitment to dividends, so this change will help to maintain
the fund's emphasis on conservative, high-yielding stocks.

    We also have eliminated, effective April 1, 2000, the guideline that the
fund should invest at least 10% of assets in utility bonds. The fund's bond
holdings had not substantially increased the fund's income or reduced the
volatility of its returns.

    The changes in the fund's investment guidelines are not expected to alter
its yield substantially. We believe these steps will serve shareholders well
over the long term without changing the fund's character as a relatively
conservative stock fund providing a relatively high level of current income and
the opportunity for moderate long-term growth of capital and income.

    The fund's long-term record has been solid. Its average annual return of
13.0% since inception on May 15, 1992, would have increased a $10,000
investment made then to $25,656 as of January 31, assuming the reinvestment of
income and capital gains. This result is just a bit behind the 13.6% return of
the average utility fund, even though our larger commitment to bonds proved
detrimental during the 1990s. Returns for both your fund and its real-world
competitors trailed that of the Utilities Composite Index. An index is a tough
benchmark because it bears no operating expenses or trading costs.
Nevertheless, we'll continue striving to outperform the index and our peer
funds. Our low operating costs will help us in this endeavor. In fiscal 2000,
the expense ratio of the Utilities Income Fund was 0.40%, or $4 per $1,000 in
net assets, 1.1 percentage points below the 1.50% expense ratio, or $15 per
$1,000 in assets, charged by the average utility fund.

GOLD AND PRECIOUS METALS FUND

Vanguard Gold and Precious Metals Fund gained 17.5% during the fiscal year, a
result that was very welcome to long-term gold investors, who had endured three
consecutive years of negative returns. Our fund came in 3.3 percentage points
ahead of the unmanaged Salomon Smith Barney World Gold Index and more than 20
percentage points above the average gold-oriented mutual fund, which returned
- -4.6%.

    Prices for precious metals were mixed during the fiscal year. The price of
gold bullion fluctuated from a low of $253 per troy ounce (one-twelfth of a
pound) in early July to $325 in late September. However, gold ended the year
down by only about $3, at $283 per troy ounce. The low point was reached after
the Bank of England began to auction off half of its gold reserves and the
Swiss central bank said it would do the same in 2000. Prices rebounded when 15
European central banks said that they would limit gold sales over the next five
years. Share prices of gold-mining companies, which are typically more volatile
than the price of the metal itself, soared.

    Among other precious metals, prices of palladium and platinum surged 44%
and 30%, respectively, during the 12-month period, in part because political
and economic turmoil in Russia, a major producer of both metals, raised
questions about future supplies. The price of copper, a "base metal" often
produced in association with precious metals, rose about 30% during the fiscal
year.

    The Gold and Precious Metals Fund outperformed its peers and its index
benchmark during fiscal 2000 both because of our investment adviser's emphasis
on well-established companies with solid management teams and because of the
fund's solid stake in companies that produced a mix of precious metals. M&G
Investment Management, our adviser, kept about one-quarter of the fund's assets
in platinum producers, including Impala Platinum and Anglo American Platinum,
both of whose share prices more than doubled.

    The long-term record of gold-mining stocks has been poor for a variety of
reasons, including relatively benign inflation, the end of Cold War tensions,
and large sales of gold by central banks around the world. During the ten years
ended January 31, our fund's average return was -2.7% per year. As
disappointing as that result has been, it was far better than the -6.8% average
annual return of the average gold-oriented mutual fund and a good sight better
than the -4.4% average annual return of the Salomon Smith Barney World Gold
Index.

    The chart above presents these results, along with the ending value of
hypothetical investments of $10,000 in our fund and its comparative standards
made a decade ago. Even with dividends and capital gains distributions
reinvested, the $10,000 investment in our fund would have shrunk to $7,569.
This decline of nearly 25% of the original capital compared with declines of
about 50% and 36%, respectively, in identical investments in the average
gold-oriented fund and our index benchmark. M&G Investment Management deserves
recognition for having avoided some of the damage in the precious-metals
markets during the past decade.

IN SUMMARY

The 12-month period ended January 31 provided abundant evidence of the
volatility inherent in the stock market and, in particular, the wide divergence
in returns among discrete industry groups. When you invest in a sector mutual
fund, such as one of our five Specialized Funds, you incur industry-specific
risks--such as exposure to rapid swings in the price of oil or gold--that are
less apparent in a diversified stock portfolio. Given these extra risks, we
encourage you, as always, to maintain a balanced mix of stock funds, bond
funds, and short-term reserves appropriate for your risk tolerance, time
horizon, and financial resources. As part of such a balanced program, low-cost
sector funds are the best way to gain additional exposure to specific market
niches.

A REPORT ON THE FUNDS' AFTER-TAX RETURNS

Beginning with this annual report, Vanguard is pleased to provide a review of
the after-tax performance of four of our five Specialized Funds. We exclude the
REIT Index Fund because after-tax return data for comparable funds are
unavailable.

    The figures in this report demonstrate the considerable impact that federal
income taxes can have on a fund's return--an important consideration for
investors who own mutual funds in taxable accounts. While the pretax return is
most often used to tally a fund's performance, the fund's after-tax return,
which accounts for taxes on distributions of capital gains and income
dividends, is a better representation of the return that many investors
actually received. If you own a fund in a tax-deferred account such as an
individual retirement account or a 401(k), this information does not apply to
you. Such accounts are not subject to current taxes.

    The table below presents the pretax and after-tax returns for your fund and
an appropriate peer group of mutual funds. Two things to keep in mind:

    - The after-tax return calculations use the top federal income tax rates in
effect at the time of each distribution. The tax burden, therefore, would be
somewhat less, and the after-tax return somewhat more, for those in lower tax
brackets.

    - The peer funds' returns are provided by Morningstar, Inc. (Elsewhere in
this report, returns for comparable mutual funds are derived from data provided
by Lipper Inc., which differ somewhat.)

 *Performance figures do not reflect the funds' transaction fees.
**Since inception (May 15, 1992) for the Utilities Income Fund.
 +Based on data from Morningstar, Inc.

    As you can see, the tax efficiency of the four funds varied considerably
during fiscal 2000. For example, the Utilities Income Fund's pretax total
return of 2.8% for the 12 months ended January 31, 2000, was reduced by taxes
to -0.3%. In other words, for investors in the highest bracket, taxes cut the
fund's pretax return by 3.1 percentage points. The after-tax return for our
Gold and Precious Metals Fund was only 0.6 percentage point lower than its
17.5% pretax return. Over the full decade ended January 31, 2000, the Energy,
Health Care, and Gold and Precious Metals Funds each delivered higher average
annual returns--both before and after taxes--than their average peers.
(Unfortunately, the Gold and Precious Metals Fund topped the average precious

metals fund by losing less money.) The Utilities Income Fund, which commenced
operations in 1992, has provided lower average annual returns--both before and
after taxes--than the average utilities fund over the past five years.

    We stress that because many interrelated factors affect how tax-friendly a
fund may be, it's very difficult to predict tax efficiency. A fund's tax
efficiency can be influenced by its turnover rate, the types of securities it
holds, the accounting practices it uses when selling shares, and the net cash
flow it receives.

    Finally, it's important to understand that our calculation does not reflect
the tax effect of your own investment activities. Specifically, you may incur
additional capital gains taxes--thereby lowering your after-tax return--if you
decide to sell all or some of your shares.

A NOTE ABOUT OUR CALCULATIONS: Pretax total returns assume that all
distributions received (income dividends, short-term capital gains, and
long-term capital gains) are reinvested in new shares, while our after-tax
returns assume that distributions are reduced by any taxes owed on them before
reinvestment. Neither pretax nor after-tax returns account for redemption fees
(which apply to each of the funds, except the Utilities Income Fund). When
calculating the taxes due, we used the highest individual federal income tax
rates at the time of the distributions. Those rates are currently 39.6% for
dividends and short-term capital gains and 20% for long-term capital gains. The
calculation does not account for state and local income taxes, nor does it take
into consideration any tax adjustments that a shareholder may claim for foreign
taxes paid by any of the funds. The competitive group returns provided by
Morningstar are calculated in a manner consistent with that used for Vanguard
funds.

THE MARKETS IN PERSPECTIVE
YEAR ENDED JANUARY 31, 2000

The surprising strength of global economic growth was something of a tonic for
stocks but seemed toxic for bonds during the fiscal year ended January 31,
2000.

    Interest rates soared--causing bond prices to fall--as investors and
central banks worried that the rapid expansion in economic activity would cause
inflation to worsen. Financial markets were anything but boring, as day-to-day
price fluctuations for bonds and stocks were pronounced during the period.

U.S. STOCK MARKETS

The U.S. economy's performance was superlative during the fiscal year. Economic
output grew at an inflation-adjusted rate of about 4%, a very rapid pace for a
huge economy that has been expanding without pause for a record 107
months--nearly nine years. Growth also picked up in Asia and Europe. U.S.
unemployment fell to 4.0% of the workforce, the lowest rate in 30 years.
Inflation accelerated a bit--largely due to a 125% increase in oil prices--but
the 2.7% increase in the Consumer Price Index (CPI) was hardly extreme.
Corporate profits rose at a double-digit rate, providing some support for stock
prices, which ordinarily are hurt by rising interest rates. Even so, some of the
biggest gains were in stocks of companies with no profits at all.

    The overall market, as measured by the Wilshire 5000 Total Market Index,
recorded a 14.4% return, despite a -4.1% decline in the final month of the
fiscal year. Small- and mid-capitalization stocks, which had lagged large-cap
stocks for most of the previous five years, were the star performers. The 10.3%
return of the large-cap S&P 500 Index, which represents more than 75% of the
total market's value, badly trailed the 31.7% return of the rest of the market,
as measured by the Wilshire 4500 Completion Index.

    The rise in the market averages obscured extremely wide variations in
returns for various sectors. The small "other energy" category, home to oil
exploration and services companies that benefited from pricier oil, soared 56%.
But the consumer-staples group, which includes a number of big beverage, food,
and tobacco companies, posted a horrid -19% return. Technology companies, which
have become the market's largest sector, returned 38%. So did the
producer-durables group, which includes several fast-growing makers of
high-technology and telecommunications equipment. Higher fuel prices were a
factor in the -13% decline for the auto & transportation group.



                                      10

<PAGE>   13

    In general, the market rewarded rapid growth and even the prospect of rapid
growth while punishing sectors where actual or expected growth was subpar. This
wide disparity based on expectations is reflected in the price/earnings (P/E)
ratios for various sectors. For example, as of January 31, technology stocks in
the S&P 500 Index had a market-cap weighted average P/E ratio of 56, more than
five times the average P/E of 10 for auto & transportation stocks.

U.S. BOND MARKETS

Bond prices, which move in the opposite direction from interest rates, dropped
almost continuously throughout the fiscal year. In part, the rise in rates
reflected more borrowing by corporations and individuals. But a major factor
was the anticipation that the U.S. economy's strong expansion would either
rekindle inflation or force the Federal Reserve Board to keep boosting rates to
counter that threat.

    Official inflation gauges sent ambiguous signals. The CPI rose 2.7% during
the 12 months ended January 31, versus 1.7% during the previous 12 months.
However, the CPI's "core rate," which excludes energy and food prices, gained a
relatively modest 1.9%.

    The Fed, trying to cool the economy, raised its target for short-term
interest rates on June 30 by one-quarter percentage point. It did so by a
quarter-point again in August and November and, just after the end of our
fiscal year, on February 2--a total increase of 1 full point in just over seven
months.

    For the year, the Lehman Aggregate Bond Index, which has an
intermediate-term average maturity and is a proxy for the entire taxable bond
market, posted a -1.9% decline. On balance, yields rose by about 2 percentage
points for intermediate-term U.S. Treasury securities. The 10-year Treasury's
yield was 6.67% on January 31, 202 basis points above its 4.65% yield a year
earlier. The rate increase was less pronounced--140 basis points--for 30-year
Treasury bonds, which benefited because the federal government's growing budget
surplus is reducing the supply of long-term securities.

    This led late in the fiscal year to an unusual "inversion" of the yield
curve--instead of the usual upward-sloping curve, with yields rising steadily
along with the maturity of Treasury bonds, the highest yields were for
shorter-term bonds. As of January 31, for example, the yield of 3-year Treasury
notes was 6.69%, while 30-year bonds yielded 6.49%. Short-term rates, which are
most influenced by the Fed's moves, increased about 125 basis points; the yield
on 3-month Treasury bills rose to 5.69% on January 31, 124 basis points above
the level when the fiscal year began.

INTERNATIONAL STOCK MARKETS

Expanding economic activity and increased merger and acquisition activity were
foundations of a strong year in international stock markets, which generally
outperformed Wall Street. The biggest returns were from Pacific-region and
emerging markets that bounced back from severe slumps in the previous two
years.

    The overall return for U.S. investors from developed markets was 19.6%, as
measured by the Morgan Stanley Capital International Europe, Australasia, Far
East Index. The MSCI Pacific Free Index was up 48.0% in U.S.-dollar terms, as
returns of 38.5% in local currencies were boosted nearly 10 percentage points
due to a rise in the value of the Japanese yen versus the dollar. In Europe,
currency fluctuations had the opposite effect: A 20.8% local return was reduced
to 8.3% for U.S. investors because the value of European currencies generally
slumped versus the dollar.

    Emerging stock markets enjoyed a remarkable rebound. The Select Emerging
Markets Free Index returned 57.8%, making up almost all the ground lost in the
two previous years.

    During the past year, the energy sector recovered somewhat from its
relatively poor performance in the previous year. Vanguard Energy Fund returned
25.8% during the 12 months ended January 31, 2000, compared with returns of
10.3% for the S&P 500 Index and 31.2% for the average natural resources fund.

    Oil markets made a robust recovery after the Organization of Petroleum
Exporting Countries (OPEC) implemented production cutbacks in March 1999. The
price of a barrel of crude oil (42 gallons) increased from about $12 to $28
during the year. Natural gas markets also were firm, averaging $2.10 per
thousand cubic feet, despite the fact that 1999 was bracketed by two mild
winters. Profit margins for oil-refining operations were poor, due to both the
increase in oil prices and the presence of excess oil product inventories that
had to be reduced. The oil-services sector suffered from low levels of activity
by oil companies, which cut back on drilling after the collapse in oil prices
that took place during 1998.

    The best gains in the energy sector were concentrated in large oil
companies and in oil-services companies whose results are most sensitive to
developments outside the United States. Examples include Royal Dutch, Total
Fina, and Schlumberger. The stocks of domestic oil-producing companies and of
integrated-oil companies with heavy exposure to developments in the United
States fared poorly, even though the profits of these companies typically are
more influenced by higher oil and gas prices than are results for companies
with heavy foreign exposure. One possible reason for this disparity in
performance is that it is becoming increasingly difficult to find new reserves
to replace oil and gas production in the United States. Another weight on
oil-sector stocks may have been sales by value investment managers facing
redemptions from mutual fund shareholders and other investors.

    As world economic activity picks up in 2000, we expect oil demand to grow
by 2.4%. A large portion of the increased demand during 1999 was met by a
reduction of inventories, which are now quite low. As a result, demand for oil
from OPEC will be about 2 million barrels a day higher in 2000 than last year.
It should not be difficult for the cartel to increase production without
causing prices to fall significantly. Therefore, we think it is reasonable to
expect that oil's price will average well above $20 per barrel for some time to
come. Natural gas markets in North America also will remain firm, and we expect
gas prices to continue rising.

    Rising demand and rising prices create a very positive environment for
energy companies. In last year's annual report, written when oil was selling
for about $12 per barrel, we concluded that conditions were setting up for "a
strong recovery in the not-too-distant future." This recovery has taken place.
However, energy stocks, in our view, reflect only part of this improvement in
conditions. More gains are possible once the market concludes, as we have, that
the oil-price collapse of 1998 is not likely to be repeated soon.

INVESTMENT PHILOSOPHY

Each fund reflects a belief that investors who seek to emphasize a given
economic sector as part of a long-term, balanced investment program are best
served by holding a portfolio of securities well-diversified across that
sector.

REPORT FROM M&G INVESTMENT
MANAGEMENT LTD.
GOLD AND PRECIOUS METALS FUND

Vanguard Gold and Precious Metals Fund posted a 17.5% return during the fiscal
year ended January 31, 2000, despite a difficult environment for gold-mining
stocks. This result compared quite favorably with the -4.6% return of the
average gold-oriented mutual fund and the 14.2% gain recorded by the Salomon
Smith Barney World Gold Index.

    On balance, the price of gold bullion declined about 1% during the 12
months. This small change disguised significant interim volatility. Gold prices
fell sharply in May after the Bank of England announced that it would sell more
than half its gold reserves. Prices recovered dramatically in September when
European central banks announced restrictions on sales, but this brief period
of euphoria ended when it became evident that a number of gold companies were
being hurt by their own hedging programs (selling gold in anticipation of
future production). Finally, gold prices were hurt by the uneventful transition
to 2000, as those investors who had bought gold shares as a safe haven sold
them when doomsday scenarios didn't come to pass.

    The fund outperformed its benchmarks largely due to its high exposure to
platinum producers (around 25% of holdings), most notably Impala Platinum and
Anglo American Platinum. Demand for platinum increased markedly during the year
due to concerns about supply from Russia--one of the world's major producers.
Companies with well-diversified mining interests (which as a group constitute
about 20% of the fund), such as M.I.M. Holdings, Rio Tinto, and
Freeport-McMoRan, also performed well.

    Our performance relative to our benchmarks also was helped by our
below-market exposure to companies that are solely gold producers. The Salomon
Smith Barney World Gold Index is dominated by four large gold producers, only
one of which, Newmont Mining, had a good performance. Our 6% stake in Newmont
helped the fund's performance, as did our small exposure to the three other
firms.

    Holdings that hindered our performance included Aurora Gold and Lihir Gold,
whose results were hurt by political unrest in Indonesia, and several smaller,
more speculative issues.

    We continued to increase the portfolio's exposure to mining's blue chip
companies through purchases of WMC and Lonmin. We added a stake in Harmony Gold
Mining, a relatively cheap "pure play" on gold that will benefit from any
recovery in the metal's price. Our main sales were a few small, speculative
positions, such as Golden Star Resources and Greenstone Resources, which we were
able to jettison thanks to increased liquidity in the market. In addition, we
took profits on Euro-Nevada Mining after its price rose.

    We are reasonably optimistic that the problems afflicting gold prices in
1999 will be overcome and that demand for gold shares will improve. However, we
don't expect a material, lasting rebound until gold companies demonstrate a
greater willingness to restructure. In the meantime, we will generally avoid
smaller exploration stocks while concentrating on larger companies that have
strong management. In the current environment, we expect this approach to
reward our shareholders.

REPORT FROM WELLINGTON MANAGEMENT
COMPANY, LLP
HEALTH CARE FUND

Vanguard Health Care Fund gained 10.6% during the fiscal year ended January 31,
2000. This result well exceeded the -2.9% decline for the S&P Health Sector
Index and even surpassed the 10.3% return for the full S&P 500. However, our
return trailed the 29.0% gain of the average health/biotechnology mutual fund.

    After three years in which the best returns came from stocks with the
largest market capitalization, the market shifted dramatically in 1999 to favor
technology companies. In the health-care sector, this shift was manifested by
explosive gains for biotechnology companies, which, after four years of poor
performance, dominated returns during the final quarter of the fiscal year.

    Consequently, the best-performing health-care mutual funds for the fiscal
year were those that focused on biotechnology. Your fund's return was among the
best achieved by a diversified health-care fund.

    By far the biggest contribution to the fund's performance during the 12
months was that of Immunex, which soared due to the great success of its
blockbuster product Enbrel, a therapy for treating rheumatoid arthritis. Two
other biotech companies, Human Genome Sciences and IDEC Pharmaceuticals, also
were major contributors to the fund.

    Our Japanese holdings were positive performers this year, especially
Fujisawa Pharmaceutical and Takeda Chemical Industries. Among the major
pharmaceutical stocks, which as a group had a weak year, Warner-Lambert was a
standout for us. Its outstanding cholesterol drug, Lipitor, drove the company's
growth rate to the top of the industry. Warner-Lambert's bright prospects
prompted a takeover battle that appears to have been won by Pfizer.

    The health-services group was the most difficult. We added significantly to
our holdings in this area during the second half of the fiscal year because we
anticipate much better results going forward.

    The extraordinary move in biotechnology stocks late in our fiscal year left
the valuations for this group stretched. Consequently, we are shifting a
portion of our investment there to less-exploited sectors such as European
stocks. We remain committed to our strategy of broad diversification across
health-care stocks, a strategy that has resulted in the fund's record of good
long-term performance with relatively low volatility.

    The health-care industry faces numerous challenges in the year ahead, not
the least of which is the extended valuation of the stock market in general.
However, we believe that over the long term the health-care sector will be one
of the most attractive in the stock market due to two factors: new discoveries
in biomedical research and increased demand caused by favorable demographic
trends.

REPORT FROM WELLINGTON MANAGEMENT
COMPANY, LLP
UTILITIES INCOME FUND

Vanguard Utilities Income Fund returned 2.8% for the fiscal year ended January
31, 2000. Although this result was in line with the 3.3% gain of the fund's
composite index benchmark, it was well behind the 17.1% return of the average
utility fund.

    Within the utility sector, performance during the year varied widely by
type of company. Negative returns came from both electric utilities (-10.7%)
and the S&P Telephone Index (-0.7%). But natural gas utilities returned an
astounding 46.8% due to takeover activity and big gains for Enron, which
expanded its telecommunications business.

    Utilities--especially electric companies--have traditionally been interest
rate sensitive, and the sharp rise in rates during the fiscal year was
decidedly harmful for the group. Another big negative during the past
year--which was dominated by fast-growing technology and telecommunications
companies--was the market's view that utilities are not a growth industry. By
far the best performers among utility stocks were companies that attracted some
of the excitement surrounding the changing telecom business. For instance,
several electric and natural gas utilities have built fiber-optic networks
along rights-of-way that they control, thus transforming existing assets into
infrastructure for telecommunications.

    Our shortfall in performance versus the average utility fund was primarily
a reflection, we believe, of our income-oriented policies. In addition to
holding a stake in long-term bonds, we have hewed to a guideline that every
common stock we own must pay a dividend. This guideline keeps us from
participating in the more volatile, higher-growth segments of the market, where
few companies pay dividends.

    We have responded to the recent trends in the market by making some
changes: We reduced the fund's bond holdings to about 10% of assets and have
looked for higher growth in both domestic and international telephone companies
that pay dividends. (As a result of recent modifications to the fund's
investment guidelines, we intend to further reduce our bond holdings and to
increase our exposure to international utility companies. See the Report From
The Chairman for more details.) Our current exposure to non-U.S. utilities is
approximately 13% of equity assets. In terms of relative values, electric
utilities look incredibly inexpensive now. However, money is continuing to move
toward growth stocks, even though interest rates are rising.

    Our holdings were not without some notable winners during the fiscal year.
Among those that benefited from market trends were Enron (which returned
+107%), Montana Power (+63%), Sprint (+51%), and DQE (+23%). Enron's stock shot
up as the market recognized the successful development of its Enron Energy
Services subsidiary and embraced its announcement of a new business in trading
broadband fiber capacity. Sprint's stock soared because of its takeover by MCI
WorldCom. Both Montana Power and DQE are electric utilities that developed
profitable and valuable nonregulated businesses.

    We will continue to identify and invest in companies benefiting from the
important trends within the utility industry as deregulation accelerates.
Utility stocks provide both steady income and diversification, attributes that
are currently out of favor but that will be particularly valued when the
overall market environment turns less friendly. We appreciate your continued
support.

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

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

AVERAGE MATURITY. The average length of time until bonds held by a fund reach
maturity (or are called) and are repaid. In general, the longer the average
maturity, the more a fund'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 fund'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 indi-cating the most
creditworthy bond issuers and A-1 or MIG-1 indicating the most creditworthy
issuers of money market securities.

BETA. A measure of the magnitude of a fund'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 fund 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 fund's net assets invested in "cash
equivalents"--highly liquid, short-term, interest-bearing securities. This
figure does not include cash invested in futures contracts to simulate stock
and bond investment.

COUNTRY DIVERSIFICATION. The percentages of a fund's total net assets invested
in securities of various countries.

DISTRIBUTION BY CREDIT QUALITY. This breakdown of a fund'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 fund's holdings by type of issuer or
type of instrument.

DIVIDEND YIELD. The current, annualized rate of dividends paid on a share of
stock, divided by its current share price. For a fund, the weighted average
yield for stocks it holds.

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

EQUITY INVESTMENT FOCUS. This grid indicates the focus of a fund's equity
holdings in terms of two attributes: market capitalization (large, medium, or
small) and relative valuation (growth, value, or a blend).

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

FIXED-INCOME INVESTMENT FOCUS. This grid indicates the focus of a fund's
fixed-income holdings in terms of two attributes: average maturity (short,
medium, or long) and average credit quality (Treasury/agency, investment-grade
corporate, or below investment-grade).

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

FUND ALLOCATION BY REIT TYPE. An indicator of diversification, this table shows
the percentage of the fund's noncash holdings invested in various real estate
investment trusts, classified according to the types of property they
emphasize.

                                      17

<PAGE>   20


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

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

NUMBER OF BONDS. An indicator of diversification. The more separate issues a
fund holds, the less susceptible it is to a price decline stemming from the
problems of a particular bond issuer.

NUMBER OF STOCKS. An indicator of diversification. The more stocks a fund
holds, the more diversified it is and the more likely to perform in line with
the overall stock market.

PRICE/BOOK RATIO. The share price of a stock divided by its net worth, or book
value, per share. For a fund, 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 fund, 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 fund's past returns can be explained by
the returns from the overall market (or its benchmark index). If a fund's total
return were precisely synchronized with the overall market's return, its
R-squared would be 1.00. If a fund'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 fund, the weighted average return on
equity for the companies whose stocks it holds.

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

TEN LARGEST HOLDINGS/STOCKS. The percentage of equity assets or of total net
assets that a fund has invested in its ten largest stocks. As this percentage
rises, a fund's returns are likely to be more volatile because they are more
dependent on the fortunes of a few companies.

TURNOVER RATE. An indication of trading activity during the past year. Funds
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 fund's income from interest and dividends. The yield,
expressed as a percentage of the fund's net asset value, is based on income
earned over the past 30 days and is annualized, or projected forward for the
coming year. The index yield is based on the current annualized rate of
dividends paid on stocks in the index.

YIELD TO MATURITY. The rate of return an investor would receive if the
securities held by a fund were held to their maturity dates.

PERFORMANCE SUMMARY
REIT INDEX FUND

All of the data on this page represent past performance, which cannot be used to
predict future returns that may be achieved by the fund. Note, too, that both
share price and return can fluctuate widely. An investor's shares, when
redeemed, could be worth more or less than their original cost.

FINANCIAL STATEMENTS
JANUARY 31, 2000

STATEMENT OF NET ASSETS
This Statement provides a detailed list of each fund'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, bonds, etc.) and by sector
within the fund's designated industry; international securities, if significant,
may be presented in a separate group. The REIT Index Fund lists its security
holdings in descending market value order. Other assets are added to, and
liabilities are subtracted from, the value of Total Investments to calculate the
fund's Net Assets. Finally, Net Assets are divided by the outstanding shares of
the fund to arrive at its share price, or Net Asset Value (NAV) Per Share.

      At the end of the Statement of Net Assets, you will find a table
displaying the composition of the fund'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 fund had available to distribute to shareholders as income dividends or
capital gains as of the statement date, but may differ because certain
investments or transactions may be treated differently for financial statement
and tax purposes. 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 fund's investments and their cost, and reflects the gains
(losses) that would be realized if the fund were to sell all of its investments
at their statement-date values.

STATEMENT OF OPERATIONS
This Statement shows dividend and interest income earned by each fund during the
reporting period, and details the operating expenses charged to the fund. These
expenses directly reduce the amount of investment income available to pay to
shareholders as dividends. This Statement also shows any Net Gain (Loss)
realized on the sale of investments, and the increase or decrease in the
Unrealized Appreciation (Depreciation) on investments during the period--these
amounts include the effect of foreign currency movements on the value of a
fund's securities. Currency gains (losses) on the translation of other assets
and liabilities are shown separately.

STATEMENT OF CHANGES IN NET ASSETS
This Statement shows how each fund's total net assets changed during the two
most recent reporting periods. The Operations section summarizes information
detailed in the Statement of Operations. The amounts shown as Distributions to
shareholders from the fund's net income and capital gains 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
fund, 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 fund's investment results and distributions to
shareholders on a per-share basis. It also presents the fund'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 fund's net income and
total returns from year to year; the relative contributions of net income and
capital gains to the fund's total return; how much it costs to operate the fund;
and the extent to which the fund tends to distribute capital gains. 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 fund for
one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard Specialized Funds comprise the Energy, Gold and Precious Metals, Health
Care, Utilities Income, and REIT Index Funds, each of which is registered under
the Investment Company Act of 1940 as a diversified open-end investment company,
or mutual fund. The Energy, Gold and Precious Metals, Health Care, and Utilities
Income Funds may invest in securities of foreign issuers, which may subject them
to investment risks not normally associated with investing in securities of
United States corporations. Certain investments of the Utilities Income Fund are
in debt instruments for which the issuers' abilities to meet their obligations
may be affected by economic developments in the utilities industry.

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

     1. SECURITY VALUATION: 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. Precious metals are valued at the mean of the latest quoted bid and
asked prices. 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. FORWARD CURRENCY CONTRACTS: The Health Care Fund enters into forward
currency contracts to protect the value of securities and related receivables
and payables against changes in future foreign exchange rates. The fund'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.

     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 forward currency contract gains
(losses).

     4. REPURCHASE AGREEMENTS: The funds, 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. The funds may also invest directly in repurchase agreements.
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.

     5. DISTRIBUTIONS: Distributions to shareholders are recorded on the
ex-dividend date. Distributions are determined on a tax basis and may differ
from net investment income and realized capital gains for financial reporting
purposes.


                                       48
<PAGE>   51

     6. OTHER: Dividend income is recorded on the ex-dividend date. Security
transactions are accounted for on the date 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 respective securities. Fees assessed on redemptions
of capital shares are credited to paid in capital.

B. Wellington Management Company, LLP, provides investment advisory services to
the Energy, Health Care, and Utilities Income Funds for fees calculated at an
annual percentage rate of average net assets. For the year ended January 31,
2000, the investment advisory fees of the Energy, Health Care, and Utilities
Income Funds represented an effective annual rate of 0.06% of each fund's
average net assets.

     M&G Investment Management Ltd. provides investment advisory services to the
Gold and Precious Metals Fund for a fee calculated at an annual percentage rate
of average net assets. For the year ended January 31, 2000, the investment
advisory fee represented an effective annual rate of 0.22% of the fund's average
net assets.

     The Vanguard Group furnishes investment advisory services to the REIT Index
Fund on an at-cost basis.

C. The Vanguard Group furnishes at cost corporate management, administrative,
marketing, and distribution services. The costs of such services are allocated
to each fund under methods approved by the Board of Trustees. Each fund has
committed to provide up to 0.40% of its net assets in capital contributions to
Vanguard. At January 31, 2000, the funds had contributed capital to Vanguard
(included in Other Assets) of:

The funds' Trustees and officers are also Directors and officers of Vanguard.

D. Vanguard has asked the funds' investment advisers to direct certain security
trades, subject to obtaining the best price and execution, to brokers who have
agreed to rebate to the funds part of the commissions generated. Such rebates
are used solely to reduce the funds' management and administrative expenses. The
funds' custodian banks have also agreed to reduce their fees when the funds
maintain cash on deposit in their non-interest-bearing custody accounts. For the
year ended January 31, 2000, these arrangements reduced expenses by:

     At January 31, 2000, the Gold and Precious Metals and Health Care Funds had
net unrealized foreign currency losses resulting from the translation of other
assets and liabilities of $1,000 and $74,000, respectively.

G. Distributions are determined on a tax basis and may differ from net
investment income and realized capital gains for financial reporting purposes.

     During the year ended January 31, 2000, the funds realized net foreign
currency gains (losses) that increased (decreased) distributable net income for
tax purposes; accordingly such gains (losses) have been reclassified from
accumulated net realized gains (losses) to undistributed net investment income
as follows:

     At January 31, 2000, the Gold and Precious Metals Fund had available
realized losses of $115,176,000 to offset future net capital gains of $2,873,000
through January 31, 2005, $19,472,000 through January 31, 2006, $67,666,000
through January 31, 2007, $13,355,000 through January 31, 2008, and $11,810,000
through January 31, 2009. Certain of the fund's investments are in securities
considered to be "passive foreign investment companies," for which any
unrealized appreciation and/or realized gains are required to be included in
distributable net income for tax purposes. During the year ended January 31,
2000, the fund included $40,000 of unrealized appreciation on passive foreign
investment companies in taxable income. The fund also realized gains on the sale
of passive foreign investment companies of $3,188,000, which were included in
prior years' distributable net income for tax purposes; accordingly, such gains
have been reclassified from accumulated net realized losses to undistributed net
investment income. The cumulative total of distributions related to passive
foreign investment company holdings at January 31, 2000, was $72,000, and is
reflected in the balance of undistributed net investment income.

     At January 31, 2000, the REIT Index Fund had available realized losses of
$45,297,000 to offset future net capital gains of $7,982,000 through January 31,
2007, and $37,315,000 through January 31, 2008.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Trustees of
Vanguard Specialized Funds

In our opinion, the accompanying statements of net assets and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Vanguard Energy Fund, Vanguard Gold and Precious Metals Fund, Vanguard Health
Care Fund, Vanguard Utilities Income Fund and Vanguard REIT Index Fund
(constituting Vanguard Specialized Funds, hereafter referred to as the "Funds")
at January 31, 2000, the results of each of their operations for the year then
ended, the changes in each of their net assets for each of the two years in the
period then ended and the financial highlights for each of the periods
indicated, in conformity with accounting principles generally accepted in the
United States. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Funds'
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with auditing standards generally accepted in the
United States, which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at January 31, 2000 by
correspondence with the custodians and brokers, provide a reasonable basis for
the opinion expressed above.

THE PEOPLE WHO GOVERN YOUR FUND

The Trustees of your mutual fund are there to see that the fund is operated and
managed in your best interests since, as a shareholder, you are part owner of
the fund. Your fund Trustees also serve on the Board of Directors of The
Vanguard Group, which is owned by the funds and exists solely to provide
services to them on an at-cost basis.

     Seven of Vanguard's eight board members are independent, meaning that they
have no affiliation with Vanguard or the funds they oversee, apart from the
sizable personal investments they have made as private individuals. They bring
distinguished backgrounds in business, academia, and public service to their
task of working with Vanguard officers to establish the policies and oversee the
activities of the funds.

     Among board members' responsibilities are selecting investment advisers for
the funds; monitoring fund operations, performance, and costs; reviewing
contracts; nominating and selecting new Trustees/Directors; and electing
Vanguard officers.

     The list below provides a brief description of each Trustee's professional
affiliations. Noted in parentheses is the year in which the Trustee joined the
Vanguard Board.
