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

       Bonds provided a profitable haven during the first half of 2000, a
volatile period for global stock markets. Overall, bond prices edged higher
during the six months ended June 30 as yields fell on all but the shortest
maturity securities. Indeed, bonds' total returns topped those of the broad
stock market.

       The four Vanguard Bond Index Funds performed well, posting returns higher
than those of their average peers and closely tracking their target indexes. Two
of our funds precisely matched the returns of their benchmark indexes, while the
other two lagged by just 0.1 percentage point.

       The table at right presents the six-month total return (capital change
plus reinvested dividends) for each fund, its average mutual fund peer, and the
unmanaged bond index it tracks. Our funds' returns ranged from 3.0% for the
Short-Term Bond Index Fund to 6.4% for the Long-Term Bond Index Fund.

       On June 30, our annualized yields ranged from 6.93% for the Long-Term
Bond Index Fund to 7.29% for the Intermediate-Term Bond Index Fund. Detailed
figures for each fund, including net asset values, income dividends, yields,
credit quality, and average maturity data, are presented in the table following

THE PERIOD IN REVIEW

The first half of 2000 was a tumultuous time in financial markets, which were
buffeted by a complex set of crosscurrents. The domestic economy continued to
grow at a strong pace--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. Elsewhere in the world, growth was picking up from more subdued
levels.

       Economic growth is generally good for corporate earnings and, thus, for
stocks. But investors and economic policymakers have worried that the
combination of rapid economic growth and low unemployment would trigger sharply
higher wages and inflation. The Federal Reserve Board, in an effort to slow the
economy's momentum and forestall an inflationary outburst, continued to raise
short-term interest rates during the half-year. The Fed boosted its target for
the federal funds rate three times by a total of 1.0 percentage point (100 basis
points). In all, the Fed has raised its target rate by 175 basis points in the
past 12 months.

                                       1
<PAGE>   4

       However, the market began to anticipate an end to the Fed's campaign of
rate hikes. The result was that longer-term interest rates eased even while the
Fed was boosting short-term rates. By midyear, statistical evidence suggested a
slowing of the economy's growth rate--just the result the Fed had been seeking.

       On balance, the yield of 3-month U.S. Treasury bills climbed 52 basis
points (from 5.33% to 5.85%) during the half-year. For longer-term Treasuries,
yields rose but then began to fall after the Treasury announced that it would
use rising federal budget surpluses to buy back billions of dollars' worth of
long-term bonds. The shrinking supply caused long-term Treasuries' prices to
rise and their yields to fall. By June 30, the 30-year Treasury bond's yield
had fallen 58 basis points, from 6.48% to 5.90%. The yield of the 10-year
Treasury note fell 41 basis points, to 6.03%. Yields on high-quality corporate
bonds were flat to slightly higher. But for low-quality corporate OjunkO bonds,
prices fell and yields rose as investors worried about increased defaults.

       Corporate bonds in general provided lower total returns than government
issues for the half-year. The Lehman Aggregate Bond Index, which represents the
overall U.S. taxable bond market, returned 4.0%, consisting of an average price
increase of 0.4% and an income return of 3.6%.

       Meanwhile, the U.S. stock market, as measured by the Wilshire 5000 Total
Market Index, posted a -0.7% return for the six months. Despite the threat of
higher interest rates, growth stocks--mainly those in the technology sector
whose prices reflect high expectations for future profitability--continued to
boom for most of the first quarter of 2000. Thereafter, tech stocks fell sharply
before a bounceback in June. The switch in market sentiment may have been due to
worries that the ideal environment of rapid economic growth and low inflation
was coming to an end.

PERFORMANCE OVERVIEW

The Vanguard Bond Index Funds benefited from a steadying in the bond market
during the first half of 2000. Except for short-term and junk bonds,
fixed-income securities enjoyed modest price increases, which augmented the
interest income earned during the six months and resulted in solid total
returns. The Short-Term Bond Index Fund's six-month return of 3.0% consisted
entirely of its interest income. But each of the other funds enjoyed some price
appreciation during the half-year: 0.1% for the Intermediate-Term Bond Index
Fund, 0.5% for the Total Bond Index Fund, and 2.9% for the Long-Term Bond Index
Fund.

       The LONG-TERM BOND INDEX FUND has a longer average duration than the
average competing fund, and its price is therefore more sensitive to changes in
interest rates. In periods of falling long-term interest rates, such as the past
six months, this works to our advantage. Thus, the fund's half-year return of
6.4% was the highest among our four funds and had the largest lead (2.4
percentage points) over the average return for peer funds. The TOTAL BOND MARKET
INDEX FUND earned a 3.9% return, which was 0.5 percentage point higher than that
of its peers. The 3.0% return of the SHORT-TERM BOND INDEX FUND and the 3.6%
return of the INTERMEDIATE-TERM BOND INDEX FUND were 0.2 percentage point higher
than the average return from peer funds.

       The returns of the Short-Term and Intermediate-Term Bond Index Funds
equaled those of their relevant indexes. The Total and Long-Term Bond Index
Funds came in just 0.1 percentage point behind their index targets--a difference
reflecting the operating expenses that mutual funds incur. Indexes, of course,
exist only on paper and have no real-world expenses. So we salute the funds'
manager, Vanguard Fixed Income Group, for tracking the returns of the indexes so
closely. The group's task is made easier by the fact that our funds have some of
the lowest operating costs in the mutual fund industry.

                                       2

<PAGE>   5

Operating costs directly reduce the income that bond funds can pass on to their
share-holders. Our funds' annualized expense ratio of about 0.20%, or $2 per
$1,000 in assets, is a small fraction of the expenses incurred by peers. For
our average competitors, expense ratios range from 1.00% (or $10 per $1,000 in
assets) for short-term U.S. government funds to 1.20% ($12 per $1,000 in
assets) for general government funds. In the world of bond funds, such a
sizable cost advantage is critical to providing superior long-term results.

       Despite modest increases in 2000, bond prices at mid-year were still
below their levels in mid-1999. The adjacent table shows our funds' total
returns, broken down by interest income and price changes, for the 12 months
ended June 30. We present the 12-month figures because it's important to
consider a full year's interest income when evaluating a bond fund. And, as
always, we note that although bond prices can swing dramatically, over the long
run it is interest income that accounts for virtually all of a bond fund's
total return. At current yields, bonds can provide solid long-term returns,
particularly if inflation remains at relatively low levels.

IN SUMMARY

Paraphrasing Mark Twain, we would observe that reports on the death of
diversification are greatly exaggerated. The stock market has provided
extraordinary returns in recent years, making some investors wonder whether
diversification is an obsolete concept. We believe that the volatility in
stocks and the solid returns for bonds during the past half-year help to make
the case for balanced portfolios. Bond funds provide counterbalance to a
portfolio of stock funds, thus helping to reduce its risk. But bonds also
provide steady interest income that compounds over time, helping to build
wealth for long-term investors.

       At Vanguard, we haven't altered our advice for navigating the stormy
seas of financial markets toward long-term investment objectives. First, create
an investment plan with a balance of stock funds, bond funds, and money market
funds suited to your time horizon, investment goals, and tolerance for market
fluctuations. Once you have such a diversified plan in place, stick with it.
Avoid the impulse to alter it based on short-term events--whether those be
unsettling turbulence or glittery returns from some particular corner of the
market. "Stay the course" is timeless investment wisdom.

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 JUNE 30, 2000


       The perpetual tug-of-war in the financial markets ended in a near
stalemate during the first half of 2000, despite lots of back-and-forth
movement. On average, neither stock nor bond prices ended the period far from
where they began it. However, bonds, thanks to their superior income, outpaced
stocks in total return.

       Economic signals were conflicting. Growth continued at a rapid pace, and
corporate profits rose smartly. On the other hand, stock prices as the year
began already reflected high levels of optimism, and the market administered
severe punishment to companies that failed to live up to earnings expectations.
Also weighing on the market were concerns that the economy's vigor at a time of
low unemployment would inevitably push labor costs and other prices higher.
Indeed, higher costs for oil and natural gas pushed broad gauges of inflation
higher (the Consumer Price Index gained 2.4% for the six months and 3.7% for the
twelve months ended June 30). Yet core inflation, which excludes energy and food
items, registered a moderate 2.4% gain during the 12 months ended June 30.


       The Federal Reserve Board raised short-term interest rates by 0.25
percentage point in February and again in March, before adding a half-point
boost in May. These steps, which followed three quarter- percentage-point
increases in 1999, took the Fed's target for short-term rates to 6.5%.
Thereafter, signs of a slowing in economic activity cropped up, although it was
not certain that the Fed was done trying to throttle down the economic engine.

U.S. STOCK MARKETS

Stock prices were quite volatile during the half-year, and large day-to-day
price fluctuations in market averages were commonplace. There also were two
swift shifts in market leadership. The year began with a continuance in the
rapid rise for the OTMTO stocks (technology, media, telecommunications) that
were the market's darlings during 1999. Through mid-March, the surge in these
Onew economyO groups left Oold economyO stocks far behind. For example, the
Nasdaq Composite Index, which is dominated by tech-related stocks, gained 15.6%
and the Russell 1000 Value Index fell -10.4% during January and February. But in
mid-March, value stocks took charge and TMT stocks slumped. The Russell 1000
Value Index returned 12.1% while the Nasdaq plummeted to a -27.4% return in the
March-May period. But June brought another flip-flop: The value index declined
-4.6%, while the Nasdaq rebounded with a 14.5% return.

                                       5
<PAGE>   8

       When the half-year was over, most broad market indexes had modest
declines. The all-market Wilshire 5000 Index returned -0.7%, the
large-capitalization S&P 500 Index slipped -0.4%, and the Nasdaq fell -3.9%.
Small- and mid-cap stocks did better: The small-cap Russell 2000 Index gained
3.0% and the Wilshire 4500 Completion Index, comprising virtually all the U.S.
stocks outside of the S&P 500, eked out a 0.3% return.

U.S. BOND MARKETS

The Federal Reserve most directly influences interest rates of short-term
securities. The Fed pushed up its target federal funds rate (charged on
overnight loans between banks) by 1 percentage point to 6.5%. But yields of
3-month U.S. Treasury bills rose only half as far (0.52 percentage point, or 52
basis points to 5.85%). And yields actually declined on long-term Treasury
securities, whose prices rose. Big federal budget surpluses are causing a
shrinking supply of Treasury bonds. The 10-year Treasury note's yield fell 41
basis points to 6.03% as of June 30, and the yield of the 30-year Treasury
declined 58 basis points--from 6.48% to 5.90%--during the half-year.

       The upshot was an unusual "inversion" in the yield curve. Instead of
sloping upward--with yields increasing along with the maturity of Treasury
securities--the curve descended. The 5.90% yield of 30-year Treasuries on June
30 was 49 basis points below the 6.39% yield on 3-year Treasury notes.

       Corporate bonds did not perform as well as Treasuries for two main
reasons: a record level of new offerings and investors' concern that credit
quality might be declining. The rise in yields (and fall in prices) was slight
for higher-quality corporate bonds but more severe for high-yield "junk" bonds.
Investors grew wary of riskier bonds due to an increase in defaults. The Lehman
High Yield Bond Index saw a price decline of -5.7% during the first half of
2000, more than offsetting its six-month income of 4.5%. Tax-exempt municipal
bonds generally outperformed corporates but did not do as well as Treasury
securities. The overall taxable bond market, as measured by the Lehman Aggregate
Bond Index, returned 4.0%, as a price gain of 0.4% augmented a 3.6% income
return.

INTERNATIONAL STOCK MARKETS

International stock markets were generally unprofitable for U.S. investors due
to lack-luster local market performances and a stronger U.S. dollar during the
half-year. Although economic growth in most of Europe appeared to be
strengthening, stocks were hurt by continued economic weakness in Japan and
from expectations of higher interest rates. On the other hand, European stock
prices got some support from an increase in corporate takeovers.

       In local currencies, European stocks posted a 1.7% return in the
aggregate and stocks from the Pacific region recorded a modest decline of -2.6%.
However, the dollar's strength diminished those results for U.S. investors, for
whom the Morgan Stanley Capital International (MSCI) Europe Index returned
-3.0% and the MSCI Pacific Free Index returned -5.9%. The MSCI Europe,
Australasia, Far East (EAFE) Index of developed foreign markets registered a
-4.0% return for U.S. investors.

       The Select Emerging Markets Free Index fell -9.6% in U.S. dollars, having
declined -3.5% in local currencies. The index was hit by weakness in South
Africa (-15%) and several emerging Asian markets, including Indonesia (-44%),
Thailand (-36%), and the Philippines (-36%). The biggest gains among emerging
markets were in Israel (+27%) and Venezuela (+19%).

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 credit-worthy
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 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
JUNE 30, 2000 (unaudited)

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 fund, 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

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 otherinvestors. Both classes of shares have equal rights as to
assets and earnings, except that each class bears certain class-specific
expenses related to maintenance of shareholder accounts (included in Management
and Administrative expense), marketing and distribution, and shareholder
reporting. For the six months ended June 30, 2000, class-specific expenses
represented an annual rate of 0.16% 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, 2000, custodian fee offset arrangements reduced
expenses of the Total Bond Market Index Fund by $15,000.

E.  During the six months ended June 30, 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.
