AT VANGUARD, WE BELIEVE THAT TRADITION MATTERS

Our 9,000 crew members embrace the traditional values on which our success is
built, including integrity, hard work, thrift, teamwork, and fair dealing on
behalf of our clients.

Our report cover pays homage to three anniversaries, each of great significance
to The Vanguard Group:

- - The 200th anniversary of the Battle of the Nile, which commenced on August 1,
  1798. HMS Vanguard, the victorious British flagship at the Nile, is our
  namesake. And its motto-- "Leading the way"--serves as a guiding principle for
  our company.

- - The 100th birthday, on July 23, 1998, of Walter L. Morgan, founder of
  Wellington Fund, the oldest member of what became The Vanguard Group. Mr.
  Morgan was friend and mentor to Vanguard founder John C. Bogle, and helped to
  shape the standards and business principles that Mr. Bogle laid down for
  Vanguard at its beginning nearly 25 years ago: a stress on balanced,
  diversified investments; insistence on fair dealing and candor with clients;
  and a focus on long-term investing. To our great regret, Mr. Morgan died on
  September 2, 1998.

- - The 70th anniversary, on December 28, 1998, of the incorporation of Vanguard
  Wellington Fund. It is the nation's oldest balanced mutual fund, and one of
  only a handful of funds created in the 1920s that are still in operation.

Although Vanguard constantly tackles new challenges, adopts new technology, and
develops new services, we treasure the traditions and values that set us apart
in a crowded, competitive industry. And we salute our shareholders, whose
support and trust we strive to earn each and every day.

Interest rates moved higher and bond prices fell during the first six months of
1999. These price declines more than offset interest income for three of the
four Vanguard Bond Index Funds, resulting in negative returns for the half-year.

     The Total Bond Market Index Fund posted a -1.4% decline, a result that was
in line with its index benchmark and slightly ahead of the return of its average
peer. Our Intermediate-Term and Long-Term Bond Index Funds also had negative
returns, while our Short-Term Bond Index Fund managed a modest gain.

     The table at right presents the six-month total return (capital change plus
reinvested dividends) for each fund along with those of its comparative
standards. Detailed per-share figures for each fund, including net asset values,
yields, income dividends, and capital gains, are presented in the table that
follows this letter. The annualized yields of our funds as of June 30 ranged
from 5.95% for our Short-Term Bond Index Fund to 6.66% for
our Long-Term Bond Index Fund.

     It's important to note that semiannual returns for bond funds account for
only half of the year's interest income, while price changes occur immediately
in response to changes in interest rates. For this reason, we think it's also
useful to take into consideration a fund's interest income for a full year. The
table on page 2 presents each bond index fund's return for the past twelve
months, divided into its income and capital components.

THE PERIOD IN REVIEW

The key influences on financial markets during the first half of 1999 were the
surprising strength of the U.S. economy's long-running expansion, promising
corporate earnings, and the increasing signs that a number of shaky foreign
economies were on firmer footing. These factors were responsible for both
broad-based gains in U.S. stocks and increases in interest rates, which sent
bond prices lower.

     The overall U.S. stock market, as measured by the Wilshire 5000 Equity
Index, gained +11.8%--equivalent to more than a full year's return based on
historical norms. But the surprising strength of the U.S. economy and an
improved outlook for global



                                       1
<PAGE>   4

economic growth pushed up interest rates along with the prices of oil and many
industrial commodities. In the stock market, these factors contributed to a
notable revival in cyclical stocks--those of commodity-related companies,
machinery makers, and other firms whose profit prospects are most closely tied
to the economy's ups and downs.

     For bondholders, a surging economy has a dark side: the possibility that
accelerating growth will push up inflation, which diminishes the buying power of
future bond interest and principal payments. Interest rates held steady in
January, but rose throughout the rest of the half-year. By June 30, yields on
U.S. Treasury notes and bonds were higher by roughly 1 percentage point from
their year-end 1998 levels. The benchmark 30-year Treasury bond's yield
increased 86 basis points (0.86 percentage point), from 5.10% to 5.96%. The rate
rise was less pronounced for short-term securities, with the 3-month Treasury
bill's yield rising 33 basis points, from 4.45% on December 31, 1998, to 4.78%
on June 30.

     The Lehman Brothers Aggregate Bond Index, which has an intermediate-term
average maturity and is a benchmark for the taxable bond market, returned -1.4%,
as a -4.4% price decline more than offset +3.0% in interest income. The price
declines were larger for longer-term bonds, whose prices are more sensitive to
interest rate fluctuations.

PERFORMANCE OVERVIEW

All of our bond index funds saw the market value of their holdings fall during
the six months, although the decline was muted for our Short-Term fund.

     While fluctuations in bond prices can noticeably detract from or enhance
returns in the short run, over long periods it is interest income that accounts
for the vast majority of a bond fund's total return. Even a period as short as
one year provides a somewhat better perspective on bond returns. The adjacent
table shows that the price declines associated with rising interest rates over
the past twelve months were more than offset by the income generated for the
three shorter-term funds and very nearly offset in the Long-Term fund.

       For long-term investors who hold bond funds for their interest income,
the rise in interest rates is certainly not bad news. Higher yields result in
more attractive reinvestment rates, enhancing returns markedly over the years.
The current annualized SEC yields for our four funds were noticeably higher on
June 30 than on last December 31, when the semiannual period began. For our
Total Bond Market fund, the current yield of 6.44% is 81 basis points higher
than six months ago, while the current yields for our Short-Term,
Intermediate-Term, and Long-Term funds are higher by 94 basis points, 121 basis
points, and 101 basis points, respectively.

     As noted, our Total Bond Market fund outperformed its average mutual fund
peer, as did our Short-Term fund. The returns of the Intermediate-Term and
Long-Term funds trailed the average returns for funds in their peer groups. Our
Long-Term Bond Index Fund maintains a longer average maturity than the average
competitor tracked by

Lipper Inc. The comparisons between our funds and their peer groups for the
half-year and previous years are presented in the Performance Summaries on pages
11-13.

     It is worth noting that the skilled managers in Vanguard Fixed Income Group
have precisely matched the respective indexes for three of our four funds--a
significant feat given that indexes are not encumbered by the expenses or
transaction costs that any mutual fund must bear. Only the Long-Term Bond Index
Fund fell short of its index, and that by a slim 0.1 percentage point.

IN SUMMARY

Bonds have been overshadowed in recent years by the amazing runup in stock
prices. But we believe it is a mistake to overlook the merits of bond funds,
which include high current income in relation to stocks and the diversification
they add to a stock-oriented portfolio. Indeed, the relatively low correlation
between these two asset classes is precisely why it is important to hold a
diversified mix of assets--including stock funds, bond funds, and money market
funds--in proportions suited to your time horizon, investment goals, and risk
tolerance. Such a balanced portfolio is a time-tested means to gain exposure to
the rewards of investing while moderating the risks. Once you've developed such
a plan for yourself, we suggest that you "stay the course" toward your financial
goals.

THE MARKETS IN PERSPECTIVE
SIX MONTHS ENDED JUNE 30, 1999

[PHOTO]

A markedly improved global economic outlook during the first half of 1999 led to
mostly positive stock market returns and lower bond prices.

     As the year began, many observers expected that severe economic crises in
Asia, Russia, and some Latin American nations would restrain business activity
worldwide, even in the United States, which has been the world's economic
locomotive. By spring, however, a consensus emerged that global economic
activity was likely to be solid, if not robust. This change in sentiment stemmed
from several factors, including further vigorous growth in the U.S. economy, a
belief that Asia's slump had bottomed out, and moves in Europe to ease monetary
policy to encourage growth.

     Interest rates rose as investors stopped wondering whether the Federal
Reserve Board would lower interest rates--as it had three times in autumn
1998--and began to wonder when the Fed would increase rates to slow growth and
thereby forestall inflation. Indeed, on the final day of the period, the Fed
boosted short-term rates by 0.25 percentage point. In the stock market, the
brighter economic outlook led to a change in leadership from glamorous
large-capitalization growth stocks to value stocks and small-cap stocks, both of
which had been among Wall Street's wallflowers in recent years.

U.S. STOCK MARKETS

The rise in stock prices reflected the healthy domestic economy and improving
prospects for corporate earnings. The overall market, as measured by the
Wilshire 5000 Index, rose 11.8% during the period, while the S&P 500 Index, a
yardstick for large-cap stocks, gained 12.4%.

     Large-cap growth stocks, which are generally perceived as less vulnerable
than other stocks to economic slowdowns, continued to lead the market's climb
during the first quarter of the year. During the second quarter, however, value
stocks--especially producers of commodity products such as oil, aluminum, and
chemicals--moved to the front of the pack. Providing support were generally
upbeat corporate profit reports. Indeed, earnings gains were sufficient to send
prices higher despite rising interest rates, which often depress stock prices as
well as bond prices. For the six months, the S&P 500 Index's value stocks posted
a 14.0% return while its growth stocks gained 11.0% as a group.


                                       4
<PAGE>   7

     Small-cap stocks, as measured by the Russell 2000 Index, gained 9.3%,
although that fact masks a remarkable turnaround: Small-caps declined 5.4%
during the first quarter of 1999, then advanced 15.6% during the second quarter.
Even so, the cumulative return of the Russell 2000 over the past three years
lags the S&P 500 Index by nearly 80 percentage points (+37.6% for the Russell
2000 versus +115.2% for the S&P 500).

     Four of the top-performing sectors within the S&P 500 Index during the
half-year were solidly in the value camp--the "other energy" group (+40%);
producer durables (+26%); materials & processing (+25%); and integrated-oils
(+17%). The strongest growth-oriented sector was the irrepressible technology
group (+24%). The poor performance of the consumer staples sector (-8%) was due
in part to the gains of the U.S. dollar against most foreign currencies, which
reduced the value of earnings from overseas operations.

U.S. BOND MARKETS

The powerful economic expansion that buoyed corporate profits and stock prices
was too much of a good thing for the bond market. Inflation was well
behaved--consumer prices rose 1.4% for the six months and 2.0% for the twelve
months ended June 30--but investors and Fed policymakers clearly were concerned
that an overheated economy might yet trigger significant increases in wages and
overall prices. Certainly, there was no evidence of the "natural slowing" that
many analysts expected for the economy, which is in the longest peacetime
expansion ever.

     Yields on U.S. Treasury bonds rose by approximately 1 percentage point--a
significant rise for a six-month period. The yield of the 30-year Treasury bond
rose 86 basis points, to 5.96% on June 30 from 5.10% on December 31, 1998. The
yield of the 10-year Treasury rose 113 basis points, to 5.78% from 4.65%. Money
market rates didn't rise as far: Yields on 3-month T-bills increased on balance
by only 33 basis points, to 4.78% on June 30. Bond prices, which move in the
opposite direction from interest rates, fell. The Lehman Aggregate Bond Index, a
benchmark for investment-grade taxable bonds, declined 1.4% on a total-return
basis, as bond prices declined an average of 4.4%, outweighing the 3.0% in
interest income for the period.

INTERNATIONAL STOCK MARKETS

Led by sharp recoveries in stock prices in Japan and many emerging markets,
international stock prices generated positive returns in local currencies during
the six months. However, a pervasive rise in the value of the U.S. dollar
against other currencies reduced returns for U.S. investors (returns from abroad
are augmented when the dollar falls in value against other currencies).

     Overall, the developed markets outside the United States gained 4.1% in
U.S.-dollar terms, as measured by the Morgan Stanley Capital International
Europe, Australasia, Far East (EAFE) Index. The biggest increases were in the
Pacific region--up 27.3% in local-currency terms and 21.1% when measured in U.S.
dollars. Europe, which accounts for the lion's share of EAFE's market
capitalization, was up 8.2% in local currencies. But in U.S. dollars, the return
from European stocks was a negative 2.3%, as weakness in European
currencies--notably in the euro, the new 11-nation common currency--lopped more
than 10 percentage points from the local-currency returns. The MSCI Select
Emerging Markets Free Index shot up 31.5% in dollar terms, led by Asian markets
that rebounded from severe losses suffered in 1997 and 1998.

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

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 June 30, 1999, the funds had contributed
capital to Vanguard (included in Other Assets) of:

NOTES TO FINANCIAL STATEMENTS (continued)

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 six months ended June 30,
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
six months ended June 30, 1999, custodian fee offset arrangements reduced
expenses of the Total Bond Market Index Fund, Intermediate-Term Bond Index Fund
and Long-Term Bond Index Fund by $1,000, $4,000, and $2,000, respectively.

E.   During the six months ended June 30, 1999, purchases and sales of
investment securities other than U.S. government securities and temporary cash
investments were:

NOTICE TO SHAREHOLDERS ABOUT Y2K

As is well known by now, the approaching calendar change to 2000 has posed a
challenge to many computer systems worldwide. Computers that are not modified
could interpret "00" as 1900 rather than 2000 and produce errors in
date-dependent calculations, including bond interest payments, stock trade
settlements, retirement benefits, and other financial transactions.

OUR APPROACH

Vanguard has taken this challenge seriously. We have had a Year 2000 Project
under way since 1996 to fulfill our responsibility to safeguard our business
relationships and the security of our investors' accounts.

     Our internal systems are Year 2000-compliant. They have been renovated and
thoroughly tested and are ready for the date change. As for the external systems
that connect with ours, we have been working for many months with clients,
business partners, and providers of products and services to assess their
compliance. We have analyzed the external services we require and have developed
contingency plans--including provision for alternative providers where
appropriate.

     On New Year's Day, our telephone centers will be staffed and ready for
shareholder calls. However, we expect the volume of inquiries over the New
Year's weekend to be high, and we encourage shareholders to check their accounts
via our website or automated telephone systems, which offer much greater service
capacity and efficiency. This will also help our live representatives to provide
a higher level of service to those with specific transaction or other
service-related needs.

WHAT YOU CAN DO

     We assure you we will protect our shareholders' records, so account records
will not be lost. Nevertheless, keeping copies of current records is always
advisable. You should keep at least your third-quarter statement and any
confirmations you receive from us between October 1, 1999, and year-end.

     If you are a registered user of Access Vanguard(TM) (www.vanguard.com), you
can retrieve this information through the secure "Your Accounts" section and
print copies for your files. If you are not registered for Access Vanguard and
wish to have this flexibility, you should register as soon as possible so that
you can receive your password and become familiar with this service before the
New Year's weekend. Likewise, you may need personal identification numbers to
use our automated telephone services: Vanguard Tele-Account(R) for individual
investors (1-800-662-6273) and The VOICE(TM) Network for participants in
employer-sponsored retirement plans (1-800-523-1188).

     Our Year 2000 Project's primary goal from the start has been to prepare our
systems for business as usual on behalf of our shareholders into 2000 and
beyond. We remain confident we will meet that goal, and we look forward to
serving you in the years to come.

                       Admiral Horatio Nelson's flagship
                          at the Battle of the Nile on
                          August 1, 1798. Our founder,
                         John C. Bogle, chose the name
                        after reading Nelson's inspiring
                      tribute to his fleet: "Nothing could
                          withstand the squadron . . .
                       with the judgment of the captains,
                      together with their valour, and that
                        of the officers and men of every
                 description, it was absolutely irresistible."

                         a true investment pioneer, died
                         six weeks later on September 2.

                        The Vanguard Group's oldest fund,
                         was incorporated by Mr. Morgan
                       70 years ago, on December 28, 1928.
                            The fund was named after
                             the Duke of Wellington,
                              whose forces defeated
                            Napoleon Bonaparte at the
                           Battle of Waterloo in 1815.
