HAVE THE PRINCIPLES OF INVESTING CHANGED?

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

       We don't think so.

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

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

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

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

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

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

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

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

    - Capture as much of the market's return as possible by minimizing costs
and taxes. Costs and taxes diminish long-term returns while doing nothing to
reduce the risks you incur as an investor.

REPORT FROM THE CHAIRMAN

John J. Brennan

Bond prices generally recovered during the six months ended July 31,
2000, the first half of the Vanguard Bond Funds' fiscal year. Longer-term
Treasury bonds displayed particular strength, and all of our funds that were in
operation throughout the half-year rebounded from a disappointing fiscal 2000.
The returns for these funds ranged from 2.4% for our High-Yield Corporate Fund
to 9.0% for our Long-Term Treasury Fund.

       The adjacent table presents the six-month total return (capital change
plus reinvested dividends) for each fund com- pared with the average return of
its mutual fund competitors. The table also includes the return for Vanguard
Inflation-Protected Securities Fund, which we introduced in June. Later in this
letter, I will provide more details about inflation-indexed securities in
general and our fund in particular.

       Information on all of the Vanguard Bond Funds, including per-share net
asset values and income dividends, are presented in the table that follows this
letter. That table also lists the annualized yields of each fund, which on July
31 ranged from 3.72% for our new Inflation-Protected Securities Fund to 9.92%
for our High-Yield Corporate Fund.

       We believe that any semiannual review of bond fund returns should also
include a look at a full year's interest income. That's because six-month
returns for bond funds account for only half of the year's interest income,
while prices fully and immediately reflect movements in interest rates--rising
when rates fall and falling when rates rise. Over long periods, however, the
price effects of fluctuating interest rates tend to be offsetting, so interest
income accounts for virtually all of the total return on a bond fund. The table
on page 2 presents each fund's return for the past 12 months, divided into its
income and capital components. The high sensitivity of longer-term bonds to
changes in interest rates is clearly illustrated. During the 12 months, yields
rose on all but long-term Treasury bonds. For further information on capital and
income returns for each fund, see the Performance Summaries beginning on page
13.

THE PERIOD IN REVIEW

The financial markets were stormy during the six months ended July 31. Overall,
the economic news was good. The economy continued its robust growth--the
production of goods and services during the second quarter of 2000 was about 6%
higher than in the same period last year, even after adjusting for inflation.
Unemployment remained low, hovering around 4% of the workforce. But investors
spent much of the half-year worrying about a resurgence in inflation and the
heady valuations of many technology-related stocks. In this environment, bonds
delivered higher returns than stocks.

       The Federal Reserve Board, in an effort to slow the economy's momentum
and head off an uptick in inflation, continued to raise short-term interest
rates during the period. The Fed boosted its target for the federal funds
rate--the rate that banks charge each other for overnight loans--three times by
a total of 1.0 percentage point (100 basis points). The Fed's efforts succeeded
in pushing up short-term interest rates: The yield of 3-month U.S. Treasury
bills climbed 53 basis points to end the half-year at 6.22%. However, rates on
longer-term government issues went the other way, as the Treasury started to
repurchase its bonds for the first time since the 1930s. The shrinking supply of
long-term public debt--the government has also scaled back new bond
issuance--caused long-term Treasury prices to rise and yields to fall.

*Returns since inception, June 29, 2000.


       Evidence that the economy may be easing into a period of slower growth
mounted in June, prompting rallies in both the stock and bond markets. By July
31, the 30-year Treasury bond's yield had fallen 71 basis points to 5.78%. The
yield of the 10-year Treasury bond declined a bit less (64 basis points) to
6.03% at the end of the period.

       Led by the Treasury sector, the bond market rebounded from a difficult
fiscal 2000. The Lehman Brothers Aggregate Bond Index, a broad measure of the
U.S. bond market excluding only high-yield ("junk") bonds and municipal
securities, posted a gain of 5.3% during the six months ended July 31. Treasury
bonds in each maturity range (short-, intermediate-, and long-term) outperformed
their investment-grade corporate counterparts. The margin was greatest (4.6
percentage points) for long-term bonds. The total return of mortgage-backed
securities--5.6% according to the Lehman GNMA Index--trailed that of Treasuries
but outpaced the gains on corporate bonds. High-yield bonds struggled--the
Lehman High Yield Index had a total return of 0.0%--as investors worried about
the ability of issuers to make their interest payments.



                                       2

       The U.S. stock market, meanwhile, rose modestly during the half-year. The
Wilshire 5000 Total Market Index, which tracks the entire U.S. stock market,
returned 1.5%. The large-capitalization-dominated Standard & Poor's 500 Index
returned 3.2%, outperforming the small-cap-oriented Russell 2000 Index (up
1.3%). The Nasdaq Composite Index, which is crowded with technology stocks,
declined -3.9%.

PERFORMANCE OVERVIEW

Seven of the nine Vanguard Bond Funds that were in operation throughout the
fiscal half-year ended July 31 provided total returns that were higher than
those of competing mutual funds. The exceptions were our SHORT- and
INTERMEDIATE-TERM CORPORATE FUNDS, which lagged their peers by 0.2 percentage
point. The LONG-TERM CORPORATE FUND outpaced its rival by the same margin.

       The SHORT-, INTERMEDIATE-, and LONG-TERM TREASURY FUNDS returned 3.9%,
5.9%, and 9.0%, respectively. The Short- and Intermediate-Term Treasury Funds
delivered slightly better-than-average returns, topping their peers by 0.4 and
0.7 percentage point, respectively. The Long-Term Treasury Fund's return was
well ahead of that of its peers, which gained 6.9% on average. The SHORT-TERM
FEDERAL FUND returned 3.7%, a hair above the return for its average peer.

       Our GNMA FUND, which has an intermediate-term average maturity and
invests in mortgage-backed securities, returned 5.6%, well ahead of the 5.0%
return of the average GNMA fund. Mortgages were a good investment during the
period because home-loan rates did not respond much to the decline in long-term
Treasury bond yields. The lack of volatility meant that loan refinancing, which
results in prepayment activity and generally lower yields for mortgage
investors, was not an attractive option for many homeowners.

       Our HIGH-YIELD CORPORATE FUND turned in a solid performance in a tough
environment, returning 2.4% for the half-year. On average, high-yield bond funds
declined -1.0%, largely because they invest in lower-rated--and thus,
riskier--securities than those held by our fund. Prices fell on more speculative
bonds primarily because investors grew concerned that any slowdown in the
economy could hurt companies' abilities to service their debt obligations. In
addition, tighter credit forces companies with lower credit ratings to pay
higher rates on their bonds. Defaults were on the rise, though, fortunately,
there were none in our fund. In short, it was a distinct advantage to hold
higher-rated corporate bonds during the semiannual period. Of course, under
different economic conditions, our posture can cause the fund to underperform
its competitors, as it has from time to time.

      Our funds' generally strong showings versus their competitors during the
half-year owe in large measure to our much lower operating costs. Comparable
mutual funds have average expense ratios (expenses as a percentage of average
net assets) that range from 0.60% for short-term Treasury funds to 1.30% for
high-yield funds. Our funds' expense ratios fall between 0.21% (for the
Intermediate-Term Corporate Fund) and 0.32% (for the Long-Term Treasury Fund).
Our low costs give us a significant head start--year after year--in our effort
to provide excellent investment results. The Vanguard cost advantage means that
our funds do not have to invest in lower-rated bonds in an effort to offset high
expenses.

       Compared with their target indexes, our funds did not fare so well during
the semiannual period. Only the High-Yield Corporate Fund outpaced its
benchmark, beating the Lehman High Yield Index by 2.4 percentage points. The
GNMA Fund matched the result of the Lehman GNMA Index. Our remaining funds
trailed their indexes by a


                                       3
<PAGE>   6


range of 0.1-1.0 percentage point. Once again--as ever--costs played a role.
While our operating expenses are far lower than those of competing mutual funds,
they handicap us against the unmanaged indexes, which exist only "on paper" and
therefore incur no operating costs.

A NEW KIND OF BOND FUND

In June, we introduced VANGUARD INFLATION-PROTECTED SECURITIES FUND, which
invests primarily in inflation-indexed bonds issued by the U.S. Treasury and
other U.S. government agencies; it may also invest in inflation-indexed bonds
issued by corporations. Between June 29 and July 31, the fund had a total return
of 0.9%. We present this one-month return only for the record, as results for
such a brief period are meaningless in truth.

       The Inflation-Protected Securities Fund is unlike any other Vanguard
fund. It gives investors the opportunity to invest in a diversified bond
portfolio that offers inflation protection and moderate stability of principal.
Inflation erodes the "real" purchasing power of money over time, and investing
only in stocks or conventional bonds does not necessarily fix the problem.
Common stocks have historically generated returns well in excess of inflation
over the long term, but investors must accept substantial volatility to achieve
those gains. Conventional bonds are less volatile than stocks, but they do not
offer explicit protection against inflation. In contrast, the issuers of
inflation-indexed bonds attack the problem head-on, continually adjusting the
bonds' principal and interest payments to reflect changes in the price of goods
and services. This is significant, given that the Consumer Price Index has risen
in 49 of the last 50 years. In the event of deflation--a drop in prices--the
U.S. Treasury guarantees the repayment of at least the original face value of
its inflation-indexed securities.

       While increases in the principal value of inflation-indexed bonds are not
payable until maturity, the Inflation-Protected Securities Fund will distribute
these increases, along with dividend income, on a quarterly basis. (Note that
these adjustments may cause the fund's income stream to be more volatile than
those of traditional bond funds with similar maturity and quality
characteristics.) Because fund distributions are taxable, investors should
consider holding the fund in a tax-deferred account, such as an IRA or 401(k)
plan. Also it's important to reinvest the fund's distributions. Investors who do
not reinvest them will not maintain the purchasing power of their investment
over the long term.

       Beyond inflation protection, we believe that the Inflation-Protected
Securities Fund offers investors the opportunity to further diversify a
portfolio of stock funds, bond funds, and short-term investments.
Inflation-indexed bonds fluctuate in response to changes in real interest
rates--those that exist when inflation is subtracted from the nominal interest
rate on bonds. Real rates have historically been much more stable than nominal
interest rates, which are the driver of price changes for conventional bonds.
The U.S. Treasury has been issuing inflation-indexed bonds only since early
1997, so it is too early to conclude that they can be counted on to smooth the
inevitable swings in the stock and bond markets. But the performance of
inflation-indexed securities to date suggests that they do help to diversify a
portfolio of bonds. And to the extent that inflation is bad for stocks, these
new bonds may offer diversification to stock investors as well.

       Under the able management of Vanguard Fixed Income Group, I am confident
that Vanguard Inflation-Protected Securities Fund will deliver attractive real
returns at the lowest reasonable cost.

IN SUMMARY

Stocks certainly disappointed many investors during the six months ended July
31. After all, they've been delivering double-digit gains with regularity since
the mid-1990s and have not often trailed bonds. For long-term investors,
however, the lesson of a half-year during which bonds outpaced stocks should be
plain: Trying to "time the market" is hazardous.

       Bond investors who stayed true to their investment plan after enduring a
difficult fiscal 2000 were rewarded during the half-year. The course of interest
rates is impossible to predict. But I am confident that investors who maintain a
balanced mix of stock funds, bond funds, and short-term investments, suitable
for their time horizons, goals, and tolerance for risk, stand the best chance of
success.

IN MEMORY

It is with great sadness that I report the death of John C. Sawhill, an
independent trustee of the funds and a member of The Vanguard Group's board of
directors since 1991. John, an economist who was president and chief executive
officer of The Nature Conservancy, died on May 18 at age 63. He was a senior
lecturer at the Harvard Business School and had formerly served as president of
New York University and as deputy secretary of the U.S. Department of Energy
under President Jimmy Carter. John was a remarkable man who was full of energy,
vigor, and life. His experience and wisdom added a great deal to Vanguard, and
his death is a blow to everyone who knew and loved him. Though John's work on
behalf of our funds was often carried on behind the scenes, he was a dedicated
advocate for the best interests of our shareholders. He will be missed.

THE MARKETS IN PERSPECTIVE
SIX MONTHS ENDED JULY 31, 2000


After playing second fiddle to stocks in the past several years, bonds provided
both a smoother and a more profitable ride than stocks during the six months
ended July 31, 2000. The Lehman Aggregate Bond Index--a proxy for the
investment-grade taxable bond market--recorded a 5.3% return, well ahead of the
1.5% return for the entire U.S. stock market, as measured by the Wilshire 5000
Index. Stock investors encountered considerable turbulence, as big day-to-day
fluctuations in stocks were commonplace. And outside of the United States,
stocks on average declined during the six months.

      The economic backdrop was murky. Growth was quite robust--better than 5%
after inflation--in the United States. Overseas economies also were picking up
strength, and corporations generally registered solid profit gains. Still,
investors were uncertain whether the economic good times would keep rolling,
given that the Federal Reserve Board and other central banks were raising
interest rates during the period.

*Annualized.


       The Fed, with three rate increases totaling 1 percentage point, sought to
cool off the economy to keep it from overheating and pushing up inflation.
Because of sharply higher costs for oil and other energy products, the Consumer
Price Index gained 2.3% during the six months and 3.5% for the 12 months ended
July 31. Yet core inflation, which excludes energy and food items, registered a
moderate 2.4% gain during the 12 months ended July 31.

U.S. STOCK MARKETS

Rising profits, the powerful economy, and continued optimism--especially for the
"new economy" TMT stocks (technology, media, and telecommunications)--kept
market averages rising in February and early March. But in mid-March, value
stocks took charge and TMT stocks slumped. Market leadership flip-flopped again
in June, when growth stocks held sway, and in July, when value stocks
outperformed growth stocks.

       The period was marked not only by volatility in market averages but also
by extreme moves in individual stocks. Wall Street was unforgiving: Companies
that disappointed market expectations saw their stock prices plunge. The
large-capitalization S&P 500 Index posted a 3.2% return, more than double that
of the overall market, and the small-cap Russell 2000 Index edged up 1.3%. The
Nasdaq Composite Index, which had stratospheric gains in 1999, lost some
altitude, registering a -3.9% return.


                                       7
<PAGE>   10


       The rise in oil and natural gas prices helped oil-exploration and
services companies in the "other energy" group to post the market's biggest
gains: an average of 22%. Financial services companies, whose stocks had been
hurt by rising interest rates in 1999, rebounded with a 13% return. Another 1999
laggard, the health care sector, posted gains exceeding 9% during the past
half-year. Big drops in regional Bell companies and AT&T caused a -15% return
for the utilities sector, the worst for any market group. The materials &
processing group fell -9%, largely because higher energy costs hurt
energy-intensive companies such as chemical and aluminum makers.

U.S. BOND MARKETS

The Fed's three increases in its target federal funds rate (charged on overnight
loans between banks) elevated the rate by 1 percentage point to 6.50% during the
six months. However, because the market had anticipated some tightening by the
Fed, yields of 3-month U.S. Treasury bills rose only half as far (0.53
percentage point, or 53 basis points, to 6.22%). And on longer-term Treasury
securities, yields actually fell and prices rose. In part, this was due to a
shrinking supply of Treasury debt: A large and growing federal budget surplus
allows the Treasury to issue fewer new bonds and to buy back billions of
dollars' worth of outstanding bonds. The 10-year Treasury note's yield declined
64 basis points to 6.03% on July 31, and the yield of the 30-year Treasury fell
71 basis points to 5.78%.

       Because short-term rates moved higher while long-term rates slid, there
was an "inversion" in the U.S. Treasury yield curve. Instead of the usual upward
slope--with yields increasing along with maturity--the curve sloped downward. On
July 31, the 5.78% yield of 30-year Treasuries was 55 basis points lower than
the 6.33% yield of 3-year Treasury notes. Falling rates mean rising prices for
bonds, of course, and the 5.3% return of the Lehman Aggregate Bond Index during
the six months reflected a price gain of 1.7% in addition to an income return of
3.6%.

       Corporate bonds didn't fare as well as Treasuries, in part because of a
very different supply situation--corporations were issuing large amounts of new
debt. Also, heavy borrowing by companies and the Fed's efforts to slow the
economy raised the chances that some companies would have trouble paying their
debts. Concern about credit quality was evident in the split between returns for
low- and high-quality corporate bonds: a zero return for the Lehman High Yield
Index of low-quality "junk" bonds, versus 4.8% for the high-quality Lehman
Credit A or Better Index. Mortgage-backed bonds and municipal bonds, which also
boast high credit quality, had solid returns: 5.6% for the Lehman GNMA Index and
4.8% for the tax-exempt Lehman 7 Year Municipal Bond Index.

INTERNATIONAL STOCK MARKETS

Because of a rise in the value of the U.S. dollar against most other currencies
and a slump in Asian markets, international stocks were generally unprofitable
for U.S. investors during the past six months. Although the Morgan Stanley
Capital International Europe, Australasia, Far East (MSCI EAFE) Index of
developed foreign markets registered a 3.1% return in local currencies, the
stronger dollar resulted in a -1.7% return for U.S. investors.

       The MSCI Europe Index generated an 8.4% return in euros, the common
currency of 11 European countries. However, this was cut to a 2.8% return for
dollar-based investors. The MSCI Pacific Free Index declined -10.6% in dollars
and -8.1% in local currencies due to a slump in Japanese stocks, which account
for more than 75% of the index.

       The Select Emerging Markets Free Index fell -10.0% in U.S. dollars, stung
by weakness in South Korea (-18%), South Africa (-17%), Thailand (-50%), and
Turkey (-16%). Israel was the biggest gainer among emerging markets, with a 28%
return.

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


In a welcome turnabout from a difficult 1999, the Vanguard Bond Funds
posted strong results for the fiscal half-year ended July 31, 2000. Conditions
during the past six months were generally favorable for our funds. Yields
declined and prices rose for all but the shortest-maturity securities, resulting
in price increases for each of the funds we manage, except for the Short-Term
Corporate Fund, whose price held steady.

       To understand what has occurred so far this fiscal year, it's necessary
to go back to autumn 1998. At that time, yields on long-term U.S. Treasury bonds
had fallen below 5%. This was because of surging demand for Treasuries, which
were considered a safe haven during the financial crisis that swept global
markets after Russia defaulted on its government bonds. When it became apparent
that the crisis was not going to result in a financial Armageddon, as some had
predicted, interest rates rebounded. Rates rose through 1999 to levels that
reflected the strong demand for loans by households and corporations in the
growing economy.

       The Federal Reserve Board, attempting to slow the economy and forestall a
rise in inflation, boosted short-term interest rates three times in 1999. The
yield on the 30-year Treasury bond rose from its all-time low of 4.72% on
October 5, 1998 (during the height of the international financial crisis) to
6.48% on December 31, 1999. Because bond prices move in the opposite direction
from yields, long-term Treasury prices plummeted in 1999.

       During the first half of 2000, the U.S. economy continued to grow at an
exceptional pace--real (inflation-adjusted) gross domestic product expanded at a
5% annual rate. The Fed focused on indications that the demand for goods and
services was outstripping their available supply, which could cause a buildup in
inflationary pressures. Fed Chairman Alan Greenspan repeatedly identified the
"wealth effect" caused by the rise in stock prices as one source of excess
demand. The Fed raised its target federal funds rate (the interest charged by
banks for overnight loans) three times during the past six months, to 6.50%.
This influenced rates of short-term Treasury bills, which rose during the
period.

       Normally, bond yields rise along with short-term rates when the Fed is
tightening monetary policy. But during our fiscal half-year, yields on Treasury
bonds actually declined from 0.3 to 0.7 percentage point. The result was that
the yield curve inverted: Longer-term bonds sported lower yields than short-term
bonds.

       The reason for this unusual inversion of yields was a shrinking supply of
long-term Treasury securities. The federal government, which is expected to post
a $230 billion budget surplus this year, has started to reduce the size of its
auctions of new securities and has begun buying back $30 billion of its
outstanding debt. Given the strong economy and huge federal tax revenues
(federal tax receipts as a percentage of gross domestic product are at the
highest level since World War II), it's now projected that the Treasury will be
able to pay off all of its outstanding marketable debt by the end of this
decade.


                                       9
<PAGE>   12

       In other sectors of the bond market, yields didn't follow the lead of
Treasury bonds. Government agency and mortgage-backed securities didn't enjoy
the price gains seen for Treasuries, in part because issuance of new agency and
mortgage-backed securities rose. Corporate bonds were relatively hard hit by
"event risk"--the chance that shareholder-friendly actions such as stock
repurchases, leveraged buyouts, and spinoffs would hurt a company's
creditworthiness. The sensitivity to this type of action was so high during the
period that even the rumor of such a move caused a decline in the price of a
company's bonds--and an increase in yield.

A REVIEW OF OUR FUNDS

The decline in longer-term interest rates during the six months ended July 31
served as a tailwind, in the form of positive capital returns, that augmented
the income generated by our funds. During the fiscal half-year, we maintained
the funds' average durations (a measure of the sensitivity of a bond's price to
changes in interest rates) below those of their benchmarks. The result was that
we didn't benefit as much as our index targets from the decline in interest
rates during the period. However, compared with peer funds, our
Intermediate-Term and Long-Term Funds generally have longer durations and, thus,
greater price gains than our competitors in an environment of falling interest
rates.

       As noted earlier, demand for Treasury securities was high relative to the
demand for other debt instruments. As a result, corporate bonds underperformed
their Treasury counterparts during the period. This is a 180-degree swing from
fiscal 1999, when a reversal of the flight to quality helped our corporate bond
funds to outperform Treasuries.

       On June 29, 2000, Vanguard introduced the Inflation-Protected Securities
Fund. As of July 31, the fund's characteristics closely matched those of the
overall market for inflation-indexed securities, and they will continue to do so
in the future. See the Report From The Chairman beginning on page 1 for more
details on the Vanguard Inflation-Protected Securities Fund.

THE RISKS AHEAD

In the last two months, signs have emerged that the economy's rapid growth pace
is slowing. These signs have led many market participants to believe that the
Fed is at or near the end of its policy-tightening cycle. If they are correct,
the environment should be favorable for bond investors. However, if the economy
resumes growth at or near the rapid rates experienced during most of the first
half of 2000, the Fed may raise short-term interest rates again. This would have
a ripple effect and push up rates across the entire spectrum of maturities. We
believe that corporate bonds still provide attractive yield premiums in light of
our view that the economy will continue to grow at a healthy pace.

       The Vanguard Bond Funds provide a full array of maturity options so that
investors can match their own needs fairly closely. We believe it's important
for investors to periodically reevaluate their holdings as risk and return
relationships change. What will not change is our commitment 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

During the six months ended July 31, 2000, interest rates on intermediate- and
long-term U.S. Treasury securities fell approximately 60 basis points (0.60
percentage point), creating a favorable environment for fixed income securities.
This decline occurred despite the fact that the Federal Reserve Board was
actively raising short-term rates. Overall, the drop in rates can be attributed
to several factors. Most important, interest rates on Treasury securities fell
because the federal budget surplus has reduced the Treasury's borrowing needs.
At the same time, the Treasury has been actively buying back its longer-maturity
obligations in the open market, forcing yields lower.

       The GNMA, Long-Term Corporate, and High-Yield Corporate Funds are all
affected by the direction of interest rates, but to varying degrees. As time has
proven, the GNMA Fund basically behaves as an intermediate-term bond fund, and
it should not fluctuate in price as much as a long-term bond fund in response to
interest rate changes. (However, the GNMA Fund's average duration--a measure of
the fund's sensitivity to changes in interest rates--can actually change
dramatically with large swings in interest rates.)

       The Long-Term Corporate Fund is quite sensitive to changes in interest
rates. So, as the yield on long-term Treasury securities fell during the past
six months, the net asset value of the Long-Term Corporate Fund might have been
expected to rise handsomely. However, the risk premium--or "yield spread"--for
corporate bonds expanded, preventing yields on long-term corporate bonds from
falling as much as they might have otherwise. The risk premium is the additional
yield available to investors for investing in lower-quality bonds. (Treasury
bonds have no credit risk.) The wider risk premiums existed even though
corporate profits were strong and the domestic economy was healthy. The
High-Yield Corporate Fund is also influenced greatly by risk premiums. In fact,
changes in interest rates often do not have a particularly strong influence on
the prices of high-yield bonds. Rather, the credit quality of the issuers in the
portfolio is usually the critical determinant of price behavior. Therefore, the
High-Yield Corporate Fund benefited less than the other two funds from the
interest rate decline.

       It is unusual for risk premiums in the corporate bond market to expand
during a period of strong economic growth. Historically, a strong economy has
been a favorable backdrop for keeping risk premiums relatively narrow.

GNMA FUND

The investment environment for the GNMA Fund improved over the past six months.
With yields on U.S. Treasury securities generally stable to lower from January
through July 2000, the price erosion that the fund experienced last year was
largely absent. A stable mortgage interest rate environment is ideal for the
GNMA Fund, allowing it to avoid the price erosion that typically occurs when
interest rates are rising sharply, while also avoiding the negative effects on
income that occur when mortgage interest rates decline and homeowners refinance
their mortgages. Although there was some interest rate volatility during the six
months, it occurred within a narrow range. The future is, as always, uncertain,
but the GNMA Fund continues to offer attractive yields relative to


                                       11
<PAGE>   14



U.S. Treasuries, and we see no reason why it should not continue to perform well
relative to other high-quality, intermediate-term bond funds.

LONG-TERM CORPORATE FUND

The Long-Term Corporate Fund's duration is slightly less than nine years, a
level consistent with its charter as a long-term, investment-grade, corporate
bond fund. The fund's relatively long duration--a more "marketlike" duration is
about five years--suggests that the fund will be extremely sensitive to changes
in long-term rates. Shareholders should understand that this interest rate
sensitivity is one of the major risks of investing in the fund. A duration of
nine years means that if corporate bond rates move up or down by 1 percentage
point, the fund's net asset value can be expected to fall or rise by 9%. The
fund has excellent call protection, meaning that most issuers of the bonds it
holds cannot redeem those bonds if interest rates decline. This protects the
fund's income stream from declining interest rates.

       The fund's other chief risk is the possibility that the creditworthiness
of the corporate bond issuers could deteriorate. To mitigate this risk, the fund
is well diversified by issuer and industry. The fund does not own
emerging-markets debt or foreign bonds denominated in currencies other than the
U.S. dollar. Generally, we purchase bonds of well-established, larger companies
with stable operating histories.

HIGH-YIELD CORPORATE FUND

While the High-Yield Corporate Fund did not have any defaults during the
half-year, the below-investment-grade--or high-yield--market struggled as
defaults and rating downgrades increased.

       The high-yield market is a hybrid. Under some market conditions, it
follows the direction of the stock market, and at other times, it behaves
similarly to the bond market. Although interest rates on intermediate-term
Treasury bonds fell and the economy grew strongly, the high-yield corporate
sector languished. Outflows from high-yield bond mutual funds continued
throughout this period, creating some selling pressure in the market. With the
Fed raising interest rates--and thus implicitly restricting credit--the
high-yield market fought against a headwind. When credit is rationed, the
marginal borrower or lower-rated issuer must pay a relatively steeper risk
premium to obtain credit. On a positive note, investors may begin to increase
their tolerance for risk if the Fed has, for the time being, finished its task
of raising rates and slowing growth. If the monetary authorities are satisfied
that inflationary pressures are subsiding and decide to relax their tightening
grip, high-yield bonds could perform very well. In a relaxed monetary
environment, risk premiums typically contract.

       We remain very selective with respect to credit. We are avoiding the
smaller start-up companies and are continuing to emphasize the higher-quality
spectrum of the below-investment-grade market. The fund's holdings continue to
be focused on cash-paying issues almost exclusively rated B or better. We
maintain a modest reserve in U.S. Treasuries to maintain 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 INVESTMENTS. 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
JULY 31, 2000 (UNAUDITED)

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. For the funds that distribute 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
Inflation-Protected Securities Fund's Distributions--Net Investment Income and
all funds' amounts of Distributions--Realized Capital Gains 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 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, 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.

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, Inflation-Protected Securities,
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 funds consistently follow such
policies in preparing their 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 by all funds except Vanguard Inflation-Protected Securities Fund, and paid
on the first business day of the following month. Quarterly income dividends
from Vanguard Inflation-Protected Securities Fund, and all funds' 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

NOTES TO FINANCIAL STATEMENTS (continued)

E. The Short-Term Corporate Fund offers two classes of shares, Investor Shares
and Institutional Shares. Institutional Shares are designed primarily for
institutional investors that meet certain administrative and servicing criteria
and have a minimum investment of $10 million. Investor Shares are offered to all
other investors. Both classes of shares have equal rights as to assets and
earnings, except that each class bears certain class-specific expenses related
to its shareholder activity. For the six months ended July 31, 2000,
class-specific expenses represented an annual rate of 0.16% and 0.07% of average
net assets of the Investor Shares and Institutional Shares, respectively.
Income, expenses not attributable to a specific class, and realized and
unrealized gains and losses on investments are allocated to each class of shares
based on its relative net assets.

F. During the six months ended July 31, 2000, purchases and sales of investment
securities other than U.S. government securities and temporary cash investments

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.

       Six of Vanguard's seven 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.

VANGUARD BOND FUNDS
STATEMENT OF NET ASSETS - JULY 31, 2000 (UNAUDITED)


The Statement of Net Assets should be read in conjunction with the Statement of
Operations, Statement of Changes in Net Assets, Financial Highlights, and Notes
to Financial Statements, all of which appear in the accompanying report. The
Statement of Net Assets for the GNMA Fund begins on page 30 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 for the funds that distribute net income to
shareholders as a dividend each day. For the Inflation-Protected Securities
Fund, Undistributed Net Investment Income represents net income earned since the
last quarterly dividend. 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.
