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/ JOHN C. BOGLE

REPORT FROM THE CHAIRMAN

Interest rates rose sharply and bond prices fell during the 12 months ended
January 31, 2000, as surprisingly strong economic growth sparked fears of higher
inflation. In this difficult environment, five of the nine Vanguard Bond Funds
posted negative total returns for the fiscal year.

     The returns of our funds varied widely according to maturity and credit
quality. Our Short-Term Corporate Fund registered the highest return, earning
2.8% for the 12 months, while our Long-Term Treasury Fund provided a total
return of -8.4%.

     The adjacent table presents the 12-month total return (capital change plus
reinvested dividends) for each fund, broken down into capital and income
components, as well as each fund's yield as of January 31. It also presents the
return for the Institutional Shares of the Short-Term Corporate Fund, which are
available for a minimum investment of $50 million.

</TABLE>

     The net asset value of each of our funds declined during the 12 months. Our
Long-Term Treasury Fund experienced the biggest price drop--nearly 14%. Prices
of existing bonds move in the opposite direction from market interest rates, so
the market value of bonds (and bond funds) rises when interest rates fall and
declines when rates move higher. The effect is most significant for longer-term
bonds, which are more sensitive than shorter-term securities to interest rate
changes. The price change of a bond or a bond fund--spelled out in its capital
return--reflects the sensitivity to interest rates. Generally, the maturities of
our funds are longer than those of their competitors. Consequently, our relative
performance--as well as our absolute results--is more affected, especially in
the short term, by the direction of rates and the magnitude of the changes.

     As we have often reminded you, interest rates--and, thus, the prices of
bonds--can shift rapidly. For example, thanks to falling interest rates, the
capital return of the Long-Term Corporate Fund was 2.9% in fiscal 1999 and 7.9%
in fiscal 1998. In fiscal




                                       1
<PAGE>   4


1997, when rates rose, the fund's capital return was -6.0%. Over long periods,
these swings have tended to be offsetting, leaving interest income as the
dominant factor in the total return for bond funds. That's why investors with
long time horizons need not be overly concerned about short-term changes in the
market value of bonds.

       Though a rise in interest rates results in an immediate decline in a bond
fund's net asset value, it has an important positive effect for long-term bond
investors: higher income. The yields of our funds on January 31 were
considerably higher than they were a year ago. The increase in yields ranged
from 0.62 percentage point for the GNMA Fund to more than 1.8 percentage points
for our Intermediate-Term Treasury Fund, whose yield was 6.73% on January 31, up
from 4.89% a year earlier. The important point about higher yields is that
reinvested income becomes more productive. Per-share figures for each fund,
including net asset values, income dividends, and any capital gains
distributions, are listed in a table that follows this letter.

FINANCIAL MARKETS IN REVIEW

During the 12 months ended January 31, the U.S. economy continued to grow. The
unemployment rate reached a 30-year low, and consumer confidence was at an
all-time high. However, good economic news is often bad news for bonds. Bond
investors viewed the continued economic expansion with trepidation because
higher growth rates can ignite higher inflation, the enemy of bonds. (Rising
prices diminish the purchasing power of a bond's interest payments.) Indeed, the
Consumer Price Index did record an increase in the inflation rate--to 2.7%
during the fiscal year ended January 31, from 1.7% during the previous 12
months. However, much of the increase stemmed from a sharp spike in oil prices.

     The yield of the 30-year Treasury bond rose 140 basis points to 6.49%
during the period, and the yield of the 10-year Treasury jumped more than 2
percentage points to 6.67%. Investors were thus being paid more for taking less
risk--a striking illustration of stress in the bond market. The yield of 3-month
T-bills rose to 5.69% from 4.45% a year ago. The Lehman Aggregate Bond
Index--which measures the entire taxable U.S. bond market and has an
intermediate-term average maturity--returned -1.9%. The Lehman Long Treasury
Index returned -8.3%.

     The Federal Reserve Board, seeking to slow the economy and preempt any
acceleration in inflation, increased short-term interest rates three times, by a
total of 75 basis points, during the fiscal year. Surprisingly, higher interest
rates did not stop the stock market's ascent, though there were some sharp
interim setbacks.

     The Wilshire 5000 Total Market Index, which tracks the entire U.S. stock
market, gained 14.4% during the fiscal year. Small- and mid-capitalization
stocks managed to outpace large-cap stocks for the first time in several years:
The large-cap-dominated Standard & Poor's 500 Index gained 10.3%, less than
one-third of the remarkable 31.7% gain of the Wilshire 4500 Completion Index
(measuring the total U.S. market except for the S&P 500 stocks). Growth stocks,
particularly technology-related issues, drove most of the gains.

FISCAL 2000 PERFORMANCE OVERVIEW

On an absolute basis, it was a disappointing 12 months for the Vanguard Bond
Funds. On a relative basis, our performance was mixed. The returns of two of our
short-term funds and our GNMA Fund surpassed those of comparable funds, but our
other funds





                                       2
<PAGE>   5

fell short of the average returns of their peers. In the case of the
Long-Term Corporate Fund, our shortfall amounted to nearly 4 percentage points.
We will note that, over the past 16 years, our funds have provided superior
annual returns relative to their competitors 79% of the time (in 86 out of 109
yearly comparisons--a total that reflects the varying lengths of time our
funds have existed). The adjacent table presents our returns compared with those
of peer funds for the 2000 fiscal year.

     Our funds generally have average maturities that are longer than those of
comparable mutual funds, a distinction that hurts our relative performance when
interest rates are rising (as they were during fiscal 2000) and helps us when
rates are stable or falling (as they were during fiscal 1999).

*Derived from data provided by Lipper Inc.

     Though our High-Yield Corporate Fund eked out a slightly positive return of
0.2%, its performance fell well short of the 2.3% total return of its average
peer. Despite rising interest rates and an increase in default rates,
higher-yielding bonds performed relatively well during the 12 months. This is
primarily because the robust health of the economy and the booming stock market
improve chances that companies will be able to make good on their debt
obligations. (Conversely, in a slowing economy, below-investment-grade bonds are
perceived to be more risky because companies may have more difficulty earning
enough to pay their debts.) The fund's investment adviser, Wellington Management
Company, LLP, emphasizes bonds that are, on average, higher in credit quality
than those of comparable funds. This approach mitigates risk but sacrifices the
higher yields available on more speculative securities. Our fund holds virtually
all of its assets in bonds rated B or higher, while our average peer holds about
15% of its assets in bonds rated below B. During fiscal 2000, the highest
returns were earned by the very riskiest securities--those that are not rated by
the major credit agencies. Our fund shuns these issues; our average peer holds
about 8% of its assets in nonrated bonds.

     Our GNMA Fund declined over the fiscal year, returning -0.9%. Though a
negative return is never good news, our return was better than the average
return of GNMA mutual funds. Mortgage-backed securities are generally less
sensitive to interest rate changes than other intermediate-term bonds. However,
they carry significant prepayment risk--when interest rates are falling, many
homeowners refinance their loans at lower rates. This added risk is why GNMAs
must pay higher yields than comparable-maturity Treasury securities.




                                       3
<PAGE>   6

The threat of prepayments was, of course, not a factor during fiscal 1999.
Generally, mortgage-backed securities earned higher income returns--and
experienced less significant capital declines--than their intermediate-term bond
counterparts.

     As noted earlier, our long-term funds fared worst, both on an absolute
basis and relative to comparable mutual funds. The Long-Term Corporate Fund,
which returned -7.4% during the 12 months, was farthest behind its average peer,
which returned -3.6%. For the past several years, the Long-Term Corporate Fund
has seen the pool of long-term high-quality bonds shrink rapidly. For example,
during 1998, bonds rated AAA and AA together represented just 15% of the new
issuance in the investment-grade market. That trend continued in 1999. As a
result, the fund's Board of Trustees recently decided to broaden the range of
securities in which the fund may invest, allowing the Long-Term Corporate Fund
to buy bonds with slightly lower credit quality. The fund's benchmark will
change from the Lehman Long Corporate AA or Better Index to the Lehman Long
Corporate A or Better Index. While this will very slightly lower the fund's
overall credit quality, it will give our adviser greater flexibility in seeking
bonds with promising returns. The fund's average maturity, and, thus its
sensitivity to interest rate changes, will not materially change.

LONG-TERM PERFORMANCE OVERVIEW

Over a longer period, eight of our nine funds have solidly outperformed bond
mutual funds with similar objectives and policies. The table below summarizes
each fund's long-term total return, comparing it with the average return of
comparable mutual funds during the same period. The table also shows how $10,000
investments in our funds and their competitors would have grown over those
periods. The Performance Summaries on pages 13 through 22 give details of the

each fund's cumulative returns for the past ten years (or its lifetime) and
year-by-year breakdowns of its income and capital returns.

     Our margins of outperformance ranged from 0.4% a year for our Short-Term
Treasury Fund to 1.7% annually for our Long-Term Corporate Fund. This edge can
add up over time. In the case of the Long-Term Corporate Fund, a $10,000
investment made ten years ago would have grown to $23,342, compared with $19,878
in its average peer--a difference of $3,464, or nearly 35% of the initial
investment.

     Only our High-Yield Corporate Fund failed to top its average peer during
the decade. However, it's important to note that our fund delivered a return
similar to the average for its competitors--and a terrific absolute result of
10.0% a year--at a considerably lower level of risk.

     For our Short-Term Treasury and Intermediate-Term Treasury Funds, the
period since inception covers a little more than eight years; for the
Intermediate-Term Corporate Fund, just over six years.

     Our strong overall performance is the result of excellent investment
management by Vanguard's Fixed Income Group and Wellington Management Company,
LLP and our significant cost advantage. Costs matter because they directly
affect performance. For the fiscal year, our funds' expense ratios (annual
expenses as a percentage of average net assets) averaged about 0.27%--$2.70 per
$1,000 invested--a small fraction of the 1.04%, or $10.40 for every $1,000,
charged by the average fixed-income fund. Because a bond fund's expenses
directly reduce the income, and thus the total return, the fund produces, lower
costs provide our funds with a significant advantage. Over long periods,
differences in costs account for virtually all of the difference in total
returns between mutual funds investing in bonds of similar maturities and credit
quality.

     Of course, the returns presented on page 4 cannot be considered a promise
of what's to come for bond investors. Over the past ten years, bond investors
have benefited from a general decline in interest rates and moderate levels of
inflation. Therefore, these returns reflect nearly ideal conditions for bonds.
What the future will bring, of course, is anyone's guess. The best predictor of
long-term returns from bonds--though it's far from infallible--is the current
yield on those bonds. Based on current yields, long-term bonds can be reasonably
expected to provide average returns of about 6.5% to 7% over the next decade or
so, a bit below the returns of the recent past but a solid result, especially if
inflation remains relatively tame.

IN SUMMARY

The recent difficulties in the bond market may prompt investors to question the
value of diversification. But abandoning laggards and chasing winners is a risky
strategy. As the last month of the fiscal year showed, the stock market can be
volatile, and consistently stellar returns are by no means guaranteed.

     The huge disparity between stock and bond returns has not shaken our belief
that investors are best served by selecting and sticking with a mix of stock,
bond, and money market funds appropriate to their investment time horizon,
goals, and risk tolerance.

A well-balanced portfolio provides exposure to the market's upside while
limiting some of the downside. Investors should keep their eyes on the far
horizon and not let interim turbulence sway them from their course.

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.

</TABLE>

     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.




                                       7
<PAGE>   10

     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.

REPORT FROM VANGUARD FIXED INCOME GROUP
SHORT-TERM TREASURY, FEDERAL, AND CORPORATE FUNDS;
INTERMEDIATE-TERM TREASURY AND CORPORATE FUNDS; AND
LONG-TERM TREASURY FUND

The fiscal year ended January 31, 2000, was an ugly period for bond investors.
Interest rates moved steadily higher in response to a strong economy that
prompted the Federal Reserve Board (the Fed) to tighten monetary policy by
raising rates. For shareholders of the Vanguard Bond Funds, increasing market
interest rates eroded net asset values.

     As the fiscal year began, the bond market was recovering from a chaotic
period following Russia's default on its debts in August 1998. The Russian
crisis initiated a wave of fear that engulfed global markets. As fear triumphed
over greed, investors seeking quality and liquidity flocked to U.S. Treasury
securities. Their buying pushed yields down to levels not seen in a generation.
On October 5, 1998, the benchmark 30-year Treasury bond yielded 4.72%. The
markets in other fixed-income securities (corporate bonds, mortgages, and
asset-backed securities) were near gridlock, so the Fed reduced short-term
interest rates three times to improve liquidity.

     The Fed's rate reductions had the desired effect: Liquidity improved for
other segments of the bond market, with spreads between bid and offering prices
returning to the near-normal levels that had prevailed in the first half of
1998. By early 1999, as the specter of financial Armageddon receded in
investors' minds, the market began to see a reversal of the flight to quality
that had sent buyers flocking to Treasuries. Investors began to focus on
economic news to determine price levels. What they saw was an American economy
that was growing very rapidly, propelled by strong consumer spending and capital
investment. Real (inflation-adjusted) gross domestic product grew at a rate of
about 4% for all of 1999, and in the second half of the year growth accelerated
to an annualized rate of nearly 6%. The demand for workers by U.S. companies
caused the unemployment rate to fall to a 30-year low. Although inflation
remained subdued, the bond market was plagued by concern that the Fed would
raise interest rates to forestall a future rise in prices. The Fed, indeed,
raised its target for short-term rates three times in increments of 25 basis
points, (four times, if we count the increase on February 2, after our
year-end). Investors had anticipated those increases by selling bonds, which
caused the steady rise in rates that we saw during the fiscal year. The 30-year
Treasury bond closed the period with a yield of 6.49%, up 1.4 percentage points
from its opening level.

     Yields increased even more for many other segments of the Treasury bond
market. In January 2000, the Treasury announced that current and projected
federal budget surpluses would enable it to cut back the issuance of 30-year
bonds and that it would begin buying back outstanding long-term bonds. The
prospect of a shrinking supply of bonds with maturities of 15 years or more
resulted in greater demand for these bonds, so their yields rose more slowly
than yields on shorter-term instruments. Yields on Treasuries with maturities
between 2 and 10 years, for example, rose a bit more than 2 percentage points
during the fiscal year.





                                       9
<PAGE>   12

     Although corporate and mortgage-backed securities also were hurt by the
rise in market rates, they generally suffered less than Treasuries. Investors
who shunned these sectors a year ago were eager purchasers during fiscal 2000,
causing a narrowing in the gap between yields of these bonds and those of
Treasuries.

A REVIEW OF OUR FUNDS

The rise in interest rates and the resulting fall in bond prices caused negative
capital returns for our funds, offsetting much or all of the income they
generated. (A breakdown of capital and income returns is presented in the
Chairman's report on page 1.)

     During fiscal 2000, we maintained the average durations of our funds below
those of their benchmarks. We thus were able to mitigate some of the damage done
to net asset values by rising interest rates (a longer duration implies
increased sensitivity to rate changes). However, our Intermediate- and Long-Term
Treasury Funds typically have higher average duration than their mutual fund
peers, a characteristic that hurts when interest rates are rising, as during the
past year. As noted above, demand for corporate securities increased this year,
which helped the corporate funds to outperform their Treasury counterparts.

THE RISKS AHEAD

At this point, the market appears to have "priced in" additional Fed tightening
of monetary policy. The consensus is that the Fed will raise its target federal
funds rate an additional 0.50% by mid-2000. Whether such steps will slow the
economy enough to suit the Fed is debatable. However, the rise in yields since
autumn 1998 has significantly boosted income from bonds, something that will
help counter the blow to prices if the Fed raises rates further than expected.
Corporate bonds provide attractive yield premiums if we are correct in our view
that the economy will continue growing at a healthy pace.

     The Vanguard Bond Funds provide a wide range of risk/return combinations so
that investors can select the fund whose characteristics best suit their needs.
It is appropriate for investors to periodically reevaluate their holdings as
risk and return relationships change. For our part, we remain committed to
providing disciplined portfolio management at the lowest possible cost.

INVESTMENT PHILOSOPHY

The funds reflect a belief that no one bond portfolio is right for all
investors. The funds offer an array of portfolios with specific maturity and
quality characteristics so investors can select the portfolio or combination of
portfolios appropriate to their needs.

REPORT FROM WELLINGTON
MANAGEMENT COMPANY, LLP
GNMA FUND; LONG-TERM CORPORATE FUND;
AND HIGH-YIELD CORPORATE FUND

Interest rates rose sharply during our fiscal year, creating an unfavorable
environment for bonds. Rates increased by about 2 percentage points (200 basis
points) on  intermediate-term Treasury bonds over the 12 months.

     The GNMA, Long-Term Corporate, and High-Yield Corporate Funds are all
affected, to varying degrees, by changes in the level and direction of interest
rates. The GNMA Fund generally behaves like an intermediate-term bond fund, and
its net asset value generally fluctuates less than that of a long-term fund.
However, large swings in interest rates--which affect homeowners' decisions to
prepay or stick with their mortgages--can lead to dramatic changes in the
expected duration of the GNMA Fund. For the Long-Term Corporate Fund, the rise
in rates during the past year caused a sharp decline in net asset value, because
long-term bonds are most sensitive to changes in rates. The High-Yield Corporate
Fund suffered less because its net asset value is usually affected more by
changes in credit quality of its bond holdings than by changes in interest
rates.

     Interest rates began rising early in the fiscal year, well before the
Federal Reserve Board's June 30 decision to boost short-term rates by 25 basis
points--the first of three such increases during the 12 months.

     The fiscal year saw above-average "risk premiums" on corporate bonds--the
additional yield available to investors for investing in these bonds rather than
in U.S. Treasury securities, which have no credit risk. The higher risk premiums
have persisted, even though corporate profits are strong and the domestic
economy is healthy, because the federal budget surplus is enabling the Treasury
to reduce its supply of securities. In the past, a strong economy tended to keep
risk premiums relatively low.

GNMA FUND

Yields increased and prices declined during fiscal 2000 for GNMAs and other
mortgage-backed securities--just as for other bonds. As a result, the total
return for your GNMA Fund was -0.9% for the 12 months. The -7.3% decline in the
market value of the fund's securities was in line with their intermediate-term
maturity structure. Most GNMA issues fared better than comparable-maturity
securities issued by the Treasury and government agencies.

     Although returns of GNMA securities in the past 12 months were
disappointing, their yields today are very generous compared with both the
current inflation rate and comparable Treasury securities. For these reasons, we
believe that future returns will be better than those achieved in fiscal 2000.
We expect a moderate amount of price volatility to continue in fixed-income
security markets--years like the past one will always occur from time to time.
However, we believe that your GNMA Fund will continue to offer yields and
long-term returns above those of similarly structured securities while also
carrying the guarantee of the U.S. government as to payment of principal and
interest.

LONG-TERM CORPORATE FUND

The average maturity of this fund's holdings is 19 years, in keeping with its
charter as an investment-grade, long-term corporate bond fund. The fund's
average duration also is




                                       11
<PAGE>   14

long, at slightly less than nine years, which indicates that the net asset value
is extremely sensitive to changes in long-term interest rates. A duration of
nine years means that if interest rates move up or down by 100 basis points (1
percentage point), the fund's net asset value can be expected to fall or rise by
9%. Rates on long-term corporate bonds rose by almost 1.5% during the fiscal
year, resulting in a -13.3% capital return for the fund and a total return of
- -7.4%. The fund has excellent call protection, meaning that most issuers of
bonds it holds cannot redeem those bonds if interest rates decline. This helps
to protect the fund's income stream from falling rates.

     As the past 12 months demonstrated, the major risk faced by the Long-Term
Corporate Fund is higher interest rates. A second risk is always present as
well--that the creditworthiness of corporate bond issuers could decline. To
mitigate this risk, the fund is well diversified by issuer and industry. More
than 80% of its assets are invested in issues rated A or better, and most of the
issuers are well-established, larger companies with stable operating histories.
The fund does not own securities from emerging markets, and it invests in
foreign bonds only if they're denominated in U.S. dollars.

HIGH-YIELD CORPORATE FUND

The market for below-investment-grade, or high-yield, bonds is a hybrid one.
Under some conditions, high-yield bonds follow the direction of the stock
market; at other times, they behave like other bonds. The High-Yield Corporate
Fund squeaked out a positive return (0.2%) during the 12 months ended January 31
despite both rising interest rates and defaults on a record $23 billion worth of
high-yield bonds ($5 billion more than the old record set in 1991). The vibrant
domestic economy and the rising stock market softened the impact of these two
blows.

     With the Fed raising interest rates, and thus implicitly restricting
credit, the high-yield market may face headwinds for another six months or so.
When rates are up, the marginal borrower or lower-rated issuer must pay a
steeper risk premium to obtain credit. We have begun to see this phenomenon.
Investors' tolerance for risk will diminish if the Fed succeeds in its effort to
slow the economy's growth rate.

     We remain very selective with respect to credit. We are avoiding smaller
start-up companies and focusing, as always, on the higher-quality spectrum of
the below-investment-grade market. The fund continues to emphasize cash-paying
issues, most of which are rated B or better. We maintain a modest reserve of
U.S. Treasury securities to ensure liquidity.

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 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 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 bond
investment.

DISTRIBUTION BY COUPON. A breakdown of the securities in a fund according to
coupon rate--the interest rate that an issuer promises to pay, expressed as an
annual percentage of face value. Securities with unusually high coupon rates may
be subject to call risk, the possibility that they will be redeemed (or
"called") early by the issuer.

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.

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

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.

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

NUMBER OF ISSUES. 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 issue.

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.

YIELD. A snapshot of a fund's interest income. 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.

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

FINANCIAL STATEMENTS
JANUARY 31, 2000

The Statements of Net Assets, integral parts of the Financial Statements for
each of the Vanguard Bond Funds, are included as an insert to this report
(except for the GNMA Fund, whose Statement of Net Assets is provided below).

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 bond type (U.S. government and agency issues,
corporate bonds, foreign bonds, etc.); corporate bonds are further classified by
industry sector. 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 of each fund, you will find a
table displaying the composition of the fund's net assets. Undistributed Net
Investment Income is usually zero because the fund distributes its net income to
shareholders as a dividend each day. Any realized gains must be distributed
annually, so the bulk of net assets consists of Paid in Capital (money invested
by shareholders). The balance shown for Accumulated Net Realized Gains usually
approximates the amount available to distribute to shareholders as 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 realized gains, will appear as negative balances.
Unrealized Appreciation (Depreciation) is the difference between the 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 interest earned by each fund during the reporting period,
and details the operating expenses charged to each class of its shares. These
expenses directly reduce the amount of investment income available to pay to
shareholders as income 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. If a
fund invested in futures contracts during the period, the results of these
investments 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. Because the fund distributes its 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
amounts of Distributions--Realized Capital Gain may not match the capital gains
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 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, and the amounts redeemed. The corresponding
numbers of Shares Issued and Redeemed are shown at the end of the Statement.
Distributions, Capital Share Transactions, and Shares Issued and Redeemed are
shown separately for each class of shares.

FINANCIAL HIGHLIGHTS

This table summarizes each fund's investment results and distributions to
shareholders on a per-share basis for each class of shares. It also presents the
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 Bond Funds comprise the Vanguard Short-Term Treasury, Short-Term
Federal, Short-Term Corporate, Intermediate-Term Treasury, Intermediate-Term
Corporate, GNMA, Long-Term Treasury, Long-Term Corporate, and High-Yield
Corporate Funds, each of which is registered under the Investment Company Act
of 1940 as a diversified open-end investment company, or mutual fund. Certain of
the funds' investments are in corporate debt instruments; the issuers'
abilities to meet these obligations may be affected by economic developments in
their respective industries.

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

   3. REPURCHASE AGREEMENTS: Each fund, along with other members of The Vanguard
Group, transfers uninvested cash balances to a Pooled Cash Account, the daily
aggregate of 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.

   4. FUTURES CONTRACTS: Each fund 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 funds may purchase or sell futures
contracts instead of bonds to take advantage of pricing differentials between
the futures contracts and the underlying bonds. The funds may also seek to take
advantage of price differences among bond market sectors by simultaneously
buying futures (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 funds and the
prices of futures contracts, and the possibility of an illiquid market.

   Futures contracts are valued based upon 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 futures gains (losses).

   5. DISTRIBUTIONS: Distributions from net investment income are declared daily
and paid on the first business day of the following month. Annual distributions
from realized capital gains, if any, are recorded on the ex-dividend date.

   6. OTHER: 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 Vanguard High-Yield Corporate Fund capital shares are credited to
paid in capital.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Trustees of
Vanguard Bond Funds

In our opinion, the accompanying statement 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 GNMA Fund (a separate fund of Vanguard Bond Funds, hereafter referred
to as the "Fund") at January 31, 2000, the  results of its operations for the
year then ended, the changes in its net assets for each  of the two years in
the period then ended and the financial highlights for each of the  five years
in the period then ended, 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 Fund's 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 custodian, provide a
reasonable basis for the opinion expressed above.

We have also audited the financial statements of Vanguard Short-Term Treasury
Fund, Vanguard Short-Term Federal Fund, Vanguard Short-Term Corporate Fund,
Vanguard Intermediate-Term Treasury Fund, Vanguard Intermediate-Term Corporate
Fund,  Vanguard Long-Term Treasury Fund, Vanguard Long-Term Corporate Fund and
Vanguard High-Yield Corporate Fund at January 31, 2000, and we have issued our
report thereon. An insert to this Annual Report containing our report on the
financial statements of these funds is available from Vanguard Bond Funds.

VANGUARD BOND FUNDS

STATEMENT OF NET ASSETS  -  JANUARY 31, 2000

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. The
Statement of Net Assets for the GNMA Fund ~begins on page 33 of that report.

      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 bond type (U.S. government and agency issues,
corporate bonds, foreign bonds, etc.); corporate bonds are ~further classified
by industry sector. 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 of each fund, you will find a
table displaying the composition of the fund's net assets. Undistributed Net
Investment Income is usually zero because ~the fund distributes its net income
to shareholders as a dividend each day. Any realized gains must ~be distributed
annually, so the bulk of net assets consists of Paid in Capital (money invested
by ~shareholders). The balance shown for Accumulated Net Realized Gains usually
approximates the amount available to distribute to shareholders as 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 realized gains, will appear as negative balances.
Unrealized Appreciation (Depreciation) is the ~difference between the 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.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Trustees of
Vanguard Bond 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 appearing in the annual report to shareholders present fairly, in all
material respects, the financial position of Vanguard Short-Term Treasury Fund,
Vanguard Short-Term Federal Fund, Vanguard Short-Term Corporate Fund, Vanguard
Intermediate-Term Treasury Fund, Vanguard Intermediate-Term Corporate Fund,
Vanguard Long-Term Treasury Fund, Vanguard Long-Term Corporate Fund and Vanguard
High-Yield Corporate Fund (separate funds of Vanguard Bond 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 five years in the period then ended, 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.
