FELLOW SHAREHOLDERS:

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

John C. Bogle


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 nearly
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.

REPORT FROM THE CHAIRMAN

John J. Brennan


Rising interest rates prompted by a surprisingly durable and powerful economic
expansion caused bond prices to fall during 1999. For the overall U.S. bond
market, the result was the worst returns in five years. Returns for the Vanguard
Bond Index Funds ranged from a modest gain for our Short-Term Bond Index Fund to
a -7.9% return for our Long-Term Bond Index Fund.

       Our flagship Vanguard Total Bond Market Index Fund posted a -0.8% return,
as falling prices for its bond holdings more than offset its interest income.
This result matched the return for our target index and was better--by nearly a
full percentage point--than the return of the fund's average peer, the average
intermediate-term U.S. government bond fund. While a negative return is never
good news, we note that this was the 12th consecutive year in which the Total
Bond Market Index Fund has outpaced its average peer fund--an indication that
low-cost index funds are a sound investment strategy for fixed-income investors
as well as for stock investors.

       The adjacent table presents the 1999 total return (capital change plus
reinvested dividends) for each of our funds, its average mutual fund peer, and
the unmanaged bond index it tracks. Our Short-Term Bond Index Fund outpaced its
average peer, while both the Intermediate-Term and Long-Term Bond Index Funds
trailed their peers. Detailed per-share figures for each fund, including net
asset values, yields, income dividends paid during 1999, and credit quality and
average maturity data, are presented in the table following this letter.

FINANCIAL MARKETS IN REVIEW

During the past year, the U.S. economy continued--with remarkable vigor--the
expansion that began back in 1991. If, as expected, growth continues into
February 2000, the expansion will be the longest in U.S. history. Economic
output in 1999 grew at a rapid inflation-adjusted pace of approximately 4%, even
though there was little slack in the economy. The unemployment rate, for
example, closed the year at a 30-year low of 4.1%.

       Stock investors reveled in this environment. The Wilshire 5000 Total
Market Index, consisting of virtually all U.S. stocks, posted a 23.8% advance.
But bond investors--along with Federal Reserve Board policymakers--were clearly
worried that growth was too strong for inflation to remain dormant. Indeed, the
pace of inflation, as measured by the


                                        1
<PAGE>   4


Consumer Price Index, did rise to 2.7% from 1.6% in 1998. Most of the increase,
however, was due to higher oil and food prices, which many observers believe
will not keep climbing so fast.

       Market interest rates began rising in earnest in February, and the
Federal Reserve joined in with three 0.25% increases in short-term rates. Rates
moved substantially higher across all maturities. The yield of the 30-year U.S.
Treasury bond stood at 6.48% on December 31, 138 basis points above its 5.10%
yield when the year began. Long-term bonds were hardest hit by the rise in
rates, as always, and their prices fell almost -15% during the year. The
all-market Lehman Brothers Aggregate Bond Index suffered a price decline of
- -7.0%, offsetting its 6.2% income return and making for a total return of -0.8%.
Rates also rose on short-term money market instruments, though not as much as
for long-term securities. The yield of 90-day Treasury bills increased 88 basis
points during 1999 to 5.33% at year-end.

       Corporate and mortgage-backed securities fared slightly better than
Treasury bonds during 1999. The spread between yields on corporate and Treasury
bonds narrowed as investors lost some of their concern about credit downgrades
and defaults. Spreads also narrowed for mortgage-backed bonds as rising interest
rates decreased the risk that homeowners would prepay mortgages through
refinancing.

1999 PERFORMANCE OVERVIEW

Total return for a bond fund has two components--the interest income earned by
the fund and the price change of the securities the fund owns. As interest rates
change, bond prices also change, in the opposite direction. During 1999, as
interest rates rose, the prices of existing bonds fell.

</TABLE>


       The extent of the price fluctuations due to changing interest rates
increases along with the average maturity or average duration of a fund. This
difference in interest rate sensitivity is apparent in the capital returns
listed in the adjacent table, which ranged from -3.3% for our Short-Term Bond
Index Fund to -13.5% for our Long-Term Bond Index Fund. Each fund's yield--the
current rate of interest income the fund is producing--rose substantially during
1999, which means that each dollar invested today earns more income than a
dollar invested a year ago. This fact is important because over long periods
fluctuations in interest rates and in prices tend to largely cancel each other
out, leaving interest income as the main element of total return for any
investment in bonds.

       The Fund Profiles starting on page 8 list each fund's average duration,
which you can use to estimate how much your fund's share price will fluctuate in
response to a change in market interest rates. For example, the average duration
of the Total Bond Market Index Fund is 5 years, which means that if interest
rates fall or rise by 1%, the fund's share price can be expected to rise or fall
by about 5%. Knowing your fund's duration can help you determine whether you can
be comfortable with potential fluctuations in the fund's net asset value.




                                        2
<PAGE>   5


       As noted on page 1, the total returns for our Total Bond Market and
Short-Term Bond Index Funds exceeded returns earned by the average funds in
their peer groups. Our Long-Term Bond Index Fund trailed its peer-group average
because its average maturity is much longer than its competitors', meaning that
rising interest rates took a greater toll on its net asset value. When interest
rates decline--as in 1997 and 1998--the longer maturity of the fund pays off
with greater share-price gains.

       In comparison with average funds in their peer groups, our funds hold
more corporate issues. This was helpful in 1999 because corporate bonds
generally outperformed Treasury securities of similar maturities. Also, our
funds were aided--as they are year after year--by having much lower operating
costs then their competitors. In 1999, each of our funds had an expense ratio of
0.20%, or $2.00 per $1,000 invested. The average expense ratios charged by funds
in the peer groups was five to six times higher, ranging from a low of 1.04%, or
$10.40 per $1,000 in assets, for the average short-term government bond fund to
1.21%, or $12.10 per $1,000, for the average general government bond fund. Such
high expense ratios confiscate a very large portion of the gross income earned
by these competing funds. High expenses also make it very difficult for a bond
fund to keep up with a low-cost index fund over the long term--a truth
illustrated by the longer-term comparisons of our funds with their peers.

LONG-TERM PERFORMANCE OVERVIEW

Vanguard Total Bond Market Index Fund--the nation's first bond index fund for
individual investors--has amassed an enviable long-term record. As the table
below shows, the fund's 7.5% average annual return outpaced the 6.4% average
return for intermediate-term government bond funds by 1.1 percentage points
during the decade of the 1990s. Hypothetical investments of $10,000 made a
decade ago in our fund and its average peer would have grown, with dividends and
capital gains reinvested, to $20,678 and $18,652, respectively. The $2,000
"Vanguard advantage" is equal to 20% of the original investment.

       Although our lower costs explain the bulk of our lead over competitors,
another factor is the skilled hand of Vanguard's Fixed Income Group, which has
managed the bond index funds from the start. Our Total Bond Market Index Fund
has tracked its benchmark, the Lehman Aggregate Bond Index, closely over the
years. And this is not an easy feat, since the index exists only on paper and
incurs no costs. Also, the index comprises more than 5,500 separate
securities--far more than a mutual fund could realistically own--so our fund
must use sampling techniques to shadow the index while holding about 720
securities.

       Our other funds haven't been around a decade, but the same advantage for
the low-cost indexing approach to bond-fund investing is apparent. Each of our
other bond index funds has outperformed its average competitor by 1.0 to 2.1
percentage points annually since they began operations on March 1, 1994.

       We also present returns for the Institutional Shares of our Total Bond
Market Index Fund. These shares were created in September 1995 and are available
for a minimum investment of $10 million.

       All our funds have closely tracked their target indexes, even though the
operating and transaction costs that we incur put us at a disadvantage versus
the theoretical indexes. Our adviser is able to make up part of the cost
disadvantage by substituting corporate issues for some government securities.
This enables the funds to earn slightly higher yields while maintaining very
high credit-quality standards.

IN SUMMARY

After a year like 1999, when stock market averages soared while bond prices
fell, the importance of diversification could easily be overlooked. That would
be a mistake, in our judgment. The important attributes of bonds--regular
interest income and greater price stability than stocks--become, if anything,
more important as the stock market reaches unprecedented valuations.

       Vanguard has long believed that an investment program should begin with
an assessment of your investment time horizon, goals, financial situation, and
tolerance for risk. And we continue to advocate a diversified portfolio of bond
funds, stock funds, and short-term reserves as a proven way to participate in
the long-term rewards of investing while being prepared for the ever-present
risks. The Vanguard Bond Index Funds are a highly diversified and highly
efficient way to fill the bond component of any investor's investment plan.

THE MARKETS IN PERSPECTIVE
YEAR ENDED DECEMBER 31, 1999

A global expansion in economic activity bolstered stocks at home and abroad
during 1999. The muscular U.S. economy provided a good bit of the oomph, but it
got an assist from solid growth in Asian, European, and Latin American economies
that had slumped in 1997 and 1998.

       Interest rates increased significantly--causing bond prices to fall--as
both investors and monetary policymakers grew concerned that economic growth was
so vigorous that it would cause inflation to accelerate.

U.S. STOCK MARKETS

The booming economy and growing corporate profits provided plenty of fuel for
stock prices during 1999. However, higher interest rates restrained the rise,
especially for financial-services and electric utility stocks regarded as
interest rate sensitive.

       U.S. economic output increased at an inflation- adjusted rate of about
4%--a very rapid pace for such a large, mature economy. Analysts estimated that
corporate profits would grow by 14% in 1999 and again in 2000. Consumer
spending, which accounts for roughly two-thirds of economic activity, was
strong. People felt prosperous, thanks to the long bull market, plentiful jobs,
and rising incomes. (After-tax personal income grew by more than 5% in 1999, and
unemployment at year-end was at a three-decade low of 4.1% of the workforce.)

</TABLE>


       The stock market, as measured by the Wilshire 5000 Index, gained 23.8%,
with more than three-quarters of the gain coming in the final quarter of 1999.
For the first time in several years, smaller stocks outpaced
large-capitalization issues. The S&P 500 Index, which is dominated by large-cap
stocks and accounts for more than three-quarters of the U.S. stock market's
total value, gained 21.0% during the year; the rest of the market gained 35.4%.

       Hidden in the market averages was an amazing divergence in stock
performance. Prices soared for most technology-related stocks, but performance
was pedestrian, at best, for most other issues. Indeed, three-fifths of stocks
on the New York Stock Exchange fell in 1999. The technology sector of the S&P
500 Index gained 74%, and the producer-durables sector, driven by huge gains for
some makers of telecommunications and technology gear, was up 49%. These results
were in stark contrast to the declines suffered by food and beverage companies
in the consumer-staples sector (-16%) and by many companies in the health-care
group (-10%).

       Investors seemed bedazzled by the prospects for growth in revenue and
profits among tech stocks, but less interested in the actual profits for nontech
companies. Remarkably, the average S&P 500 stock without earnings gained 36.5%
in 1999, while the average stock with earnings rose 11.5%. There is general
agreement that growth in Internet commerce, computers, software, wireless
communications, and other key tech sectors will be stupendous. However, there is
much disagreement about whether profits will grow so impressively, given
the intense competition. During 1999, optimists clearly ruled.


U.S. BOND MARKETS

The pickup in worldwide economic activity buoyed stock prices but depressed bond
prices. Interest rates, which move in the opposite direction from bond prices,
rose sharply. The rate increase stemmed from increased borrowing by corporations
and individuals and from investors' fears that a sizzling economy was bound to
send inflation soaring.

       The inflation evidence was ambiguous. Price increases were greater in
1999 than in 1998 at both the wholesale and consumer levels. Wholesale prices
rose 3.0%, the biggest gain since 1990. And the Consumer Price Index advanced
2.7% in 1999 after a gain of just 1.6% in 1998. However, energy prices, which
plunged in 1998 and shot up in 1999, skewed the figures in both periods. At the
consumer level, the "core rate" of inflation, which excludes food and energy
prices, was up just 1.9% in 1999, the smallest increase in 35 years.

       At midyear, the Federal Reserve Board, aiming to cool the economy a bit
to head off price pressures, began raising short-term interest rates. In all,
the Fed pushed up rates by 0.75 percentage point in three quarter-point steps.
The bond market anticipated the Fed--interest rates began rising sharply in
February--and at year-end the yield of 30-year U.S. Treasury bonds was up 1.38
percentage points (138 basis points) to 6.48%. The 10-year Treasury note--a
benchmark for mortgage lenders--rose 179 basis points, from 4.65% to 6.44%.
Short-term rates didn't rise as far; 3-month Treasury bill yields were up 88
basis points to 5.33% at year-end.

       Price declines, as usual, were greatest for long-term bonds and least for
short-term bonds. The overall market, as measured by the Lehman Aggregate Bond
Index, which has an intermediate-term average maturity, posted a -0.8% total
return in 1999. Short-term bonds generally provided returns of 2% to 3%.
Long-term bonds suffered significant price declines, and the Lehman Long
Government/Corporate Index recorded a -7.7% total return.

INTERNATIONAL STOCK MARKETS

Bullishness among stock investors was an international phenomenon in 1999. The
biggestgains came in Pacific-region and emerging markets that had suffered most
from economic slumps and currency crises during 1997 and 1998.

       Overall, the Morgan Stanley Capital International Europe, Australasia,
Far East (EAFE) Index of major developed markets produced a 27.3% return for
U.S. dollar-based investors. The MSCI Pacific Free Index gained an astounding
56.4% for U.S. investors, as a strong rise in the Japanese yen against the U.S.
dollar tacked on about 12.5 percentage points to a 43.9% return in local
currencies. In Europe, currency fluctuations had the opposite effect: European
currencies, including the new 11-nation common currency, the euro, mostly fell
against the dollar, and the 30.3% return in local currencies was nearly halved
to 15.8% in U.S. dollars.

       Emerging markets managed a stunning turnaround, as the Select Emerging
Markets Free Index rose 60.9% in U.S.-dollar terms after having plummeted -18.4%
in 1998 and -16.4% in 1997.

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 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
DECEMBER 31, 1999

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 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 Index Funds comprise the Total Bond Market Index Fund, Short-Term
Bond Index Fund, Intermediate-Term Bond Index Fund, and Long-Term Bond Index
Fund, 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
their 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 of the Vanguard Bond Index Funds, along
with other members of The Vanguard Group, transfers uninvested cash balances
into a Pooled Cash Account, which is invested in repurchase agreements secured
by U.S. government securities. Securities pledged as collateral for repurchase
agreements are held by a custodian bank until the agreements mature. Each
agreement requires that the market value of the collateral be sufficient to
cover payments of interest and principal; however, in the event of default or
bankruptcy by the other party to the agreement, retention of the collateral may
be subject to legal proceedings.

     4. 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.

     5. 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.

B. The Vanguard Group furnishes at cost investment advisory, corporate
management, administrative, marketing, and distribution services. The costs of
such services are allocated to the funds under methods approved by the Board of
Trustees. Each fund has committed to provide up to 0.40% of its net assets in
capital contributions to Vanguard. At December 31, 1999, the funds had
contributed capital to Vanguard (included in Other Assets) of:

C. The Total Bond Market Index Fund offers two classes of shares, the Investor
Shares and the 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 year ended
December 31, 1999, class-specific expenses represented an annual rate of 0.14%
and 0.04% 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.

D. The funds' custodian bank has agreed to reduce its fees when the funds
maintain cash on deposit in their non-interest-bearing custody accounts. For
the year ended December 31, 1999, custodian fee offset arrangements reduced
expenses of the Intermediate-Term Bond Index Fund and Long-Term Bond Index Fund
by $6,000, and $4,000, respectively.

E. During the year ended December 31, 1999, purchases and sales of investment
securities other than U.S. government securities and temporary cash investments

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Trustees of
Vanguard Bond Index Funds

In our opinion, the accompanying statements of net assets and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Vanguard Total Bond Market Index Fund, Vanguard Short-Term Bond Index Fund,
Vanguard Intermediate-Term Bond Index Fund, and Vanguard Long-Term Bond Index
Fund (constituting Vanguard Bond Index Funds, hereafter referred to as the
"Funds") at December 31, 1999, the results of each of their operations for the
year then ended, the changes in each of their net assets for each of the two
years in the period then ended and the financial highlights for each of the
periods indicated, in conformity with accounting principles generally accepted
in the United States. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the responsibility of the
Funds' management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements in accordance with auditing standards generally accepted
in the United States, which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits, which included confirmation of securities at December 31, 1999 by
correspondence with the custodian, provide a reasonable basis for the opinion
expressed above.

THE PEOPLE WHO GOVERN YOUR FUND

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

     Seven of Vanguard's nine 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.

affiliations. Noted in parentheses is the year in which the Trustee joined the
Vanguard Board.
