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

Municipal bond prices dipped slightly for all but the very shortest and very
longest maturities during the six months ended April 30, a period of generally
rising interest rates. All seven of our municipal bond funds posted positive
returns for the period, ranging from 1.3% for the Limited-Term Tax-Exempt Fund
to 3.5% for the Insured Long-Term Tax-Exempt and Long-Term Tax-Exempt Funds.
Importantly, each of our funds earned a higher return than that of its average
peer.

       The adjacent table presents each fund's six-month total return (capital
change plus reinvested dividends), along with a breakdown of its capital and
income components. The table also shows each fund's yield as of April 30. The
income dividends paid by our funds are generally free from federal income taxes.

 *7-day yield for the Tax-Exempt Money Market Fund; 30-day yield for other

**An investment in a money market fund is not insured or guaranteed by the
  Federal Deposit Insurance Corporation or any other government agency. Although
  the fund seeks to preserve the value of your investment at $1 per share, it is
  possible to lose money by investing in the 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 reflect current
movements in interest rates--rising when rates fall and falling when rates rise.
For perspective, we present a full year's interest income in the returns shown
in the table on page 2. Keep in mind that, while 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. A rise in interest rates causes an
immediate price decline, but the long-term effect can be beneficial because
there is more income to reinvest at higher yields. Conversely, when interest
rates drop, bond prices rise immediately, but over the long haul, lower rates
diminish the income earned on reinvested dividends.

       The table on page 3 compares the returns for each of our funds with those
of tax-exempt funds with similar maturities. And in the table following this
letter, we present each fund's net asset value at the beginning and end of the
fiscal half-year, along with the per-share amount of income dividends for the
six- and twelve-month periods. The Performance Summaries on pages 8 through 11
show each fund's returns for various periods, compared with those of an
appropriate unmanaged index.

THE PERIOD IN REVIEW

The U.S. economy displayed remarkable vigor during the six months. Its staying
power was impressive too: April marked the 109th month of uninterrupted
expansion--more than nine years without a recession. Preliminary estimates for
the first quarter of 2000 indicated that the economy was growing at a 5.4%
annual rate, a strong follow-up to the previous quarter's astounding 7.3% rate.

       A growing economy creates a good climate for stocks, and the overall
stock market, as measured by the Wilshire 5000 Total Market Index, rose 9.7% for
the half-year. However, concerns about inflation and the high valuations of many
tech stocks contributed to very high volatility. The volatility was especially
evident among small-capitalization and technology issues. The small-cap Russell
2000 Index, for example, saw a 35.2% gain from October 31 through February 29,
followed by a -12.2% decline in March and April, resulting in an 18.7% half-year
return.

       The climate was not quite so kind to bonds. The Federal Reserve Board,
fearing that the economy's rapid expansion would ignite inflation, raised
short-term interest rates by 25 basis points (0.25 percentage point) on March
21--the third quarter-point increase during the half-year and the fifth in nine
months. The yield of 3-month U.S. Treasury bills increased 74 basis points
during the six months, to 5.83% as of April 30. But yields of longer-term bonds
didn't rise as far. Indeed, the U.S. Treasury's repurchase of some of its
long-term issues caused yields on very long-term Treasury bonds to fall
slightly. The 30-year Treasury bond's yield on April 30 was 5.96%--20 basis
points below where it started the fiscal year and 66 basis points below the
6.62% yield on 3-year Treasury notes. The overall taxable bond market, as
measured by the Lehman Brothers Aggregate Bond Index, recorded a 1.4% total
return.

       Interest rates on tax-exempt municipal bonds traced a similar pattern.
Short- and intermediate-term rates rose while yields on long-term bonds were
relatively stable. The yield on top-quality 10-year munis rose 11 basis points,
and the yield of a 2-year muni climbed nearly 60 basis points. However, the
yield of a high-quality 30-year municipal bond dipped to 5.80% from 5.89% six
months earlier. (For investors in the highest federal income tax bracket, a
tax-exempt yield of 5.80% is equivalent to a 9.60% yield on taxable bonds.) The
Lehman Brothers Municipal Bond Index, which has an average maturity of about 14
years, returned 2.6% for the six months. The Report From The Adviser on page 6
provides more details about the municipal market.

PERFORMANCE OVERVIEW

As noted earlier, each of our seven municipal bond funds earned a positive
return topping that of its average peer during the half-year. Our High-Yield
Tax-Exempt Fund registered the largest margin, earning 2.3 percentage points
more than the average tax-exempt high-yield fund, while our Limited-Term
Tax-Exempt Fund outpaced its average peer only slightly. Although six months is
too brief a period to judge a mutual fund's merits, we think it's worth noting
that we achieved superior returns while maintaining credit quality higher than
that of many funds with similar maturities. We have accomplished with
considerable consistency the feat of providing high-quality portfolios with
above-average returns because of our significant cost advantage. The expense
ratio (annualized expenses as a percentage of average net assets) for our
tax-exempt funds is below 0.20% ($2.00 per $1,000 in assets), a small fraction
of the expense ratios charged by peer funds. The average tax-exempt money market
fund carries an expense ratio of 0.68% ($6.80 per $1,000). Average expense
ratios for longer-term muni bond funds range from 0.80%



                                       2
<PAGE>   5


to 1.17%. The lower expense ratios of our funds more than compensate for the
fact that higher-quality securities pay slightly lower yields than lower-quality
bonds.

       The other factor that contributes importantly to our strong performance
is the skill of our investment adviser, Vanguard Fixed Income Group, whose
adroit management and careful credit research serve shareholders well.

IN SUMMARY

For investors in fixed-income securities, the past six months were nothing to
write home about. However, even though bond returns have lagged the sizzling
stock market recently, the argument for holding bonds in a balanced portfolio is
no less persuasive. Fixed-income investments add to a portfolio's
diversification, and interest income is a valuable and durable component of
total return that, when compounded over long periods, plays an important role in
accumulating wealth. And for those in higher tax brackets, the tax-exempt status
of income from municipal bond funds is especially valuable.

       History has taught us that investors who maintain exposure to the major
asset classes through balanced portfolios of well-diversified stock funds, bond
funds, and short-term reserves generally find it easier to maintain equilibrium
in turbulent times. We urge you to base your investment plans on your own goals,
time horizon, and risk tolerance--and then to stick with those plans over the
long haul.

THE MARKETS IN PERSPECTIVE
SIX MONTHS ENDED APRIL 30, 2000

A surging economy, rising corporate profits, and enthusiasm for technology
stocks carried broad stock market indexes higher during the volatile but
generally rewarding six months ended April 30, 2000.

       Stocks rose despite a modest pickup in inflation and a rise in interest
rates, both of which did some damage to bond prices. Through the first four
months of the period, the stock market was dominated by optimism about the
long-term outlook for technology, telecommunications, and media companies. But
sentiment then shifted and the tech and telecom groups fell sharply, giving back
some of the spectacular gains achieved over the previous year or so.

       For both bond and stock investors, uncertainty centered mainly on how the
Federal Reserve Board would react to the surprising performance of the U.S.
economy, which grew at a 7.3% pace in the final three months of 1999 and at a
still-robust 5.4% during the first quarter of 2000. With U.S. unemployment at a
three-decade low of 3.9%, Fed policymakers grew increasingly concerned that
inflation was bound to worsen. The Fed raised short-term interest rates by 0.25
percentage point three times during the six-month period. These boosts,
following identical increases in June and August of 1999, took the Fed's target
for short-term rates to 6.0%. Yet the economy continued to soar--including even
the housing and automobile sectors, which often are the first to slow down in
response to higher interest rates.

 *Annualized.


       Inflation gauges provided ambiguous readings. The Consumer Price Index
increased 1.8% and 3.0% for the 6- and 12-month periods ended April 30, but much
of the acceleration in inflation was due to higher energy and food prices. The
core inflation rate, which excludes those sectors, was up a less-ominous 2.2%
over the year.

U.S. STOCK MARKETS

The technology sector, which accounts for about one-quarter of the stock
market's total value, dominated the market during the half-year, despite
suffering a sharp setback late in the period. Even after a -34% fall from March
10 through mid-April, the tech-heavy Nasdaq Composite Index registered a 30.8%
return for the six months.

       The overall stock market, as measured by the Wilshire 5000 Total Market
Index, gained 9.7%. There was a decided split in results from large- and
small-capitalization stocks.



                                       4
<PAGE>   7


The large-cap S&P 500 Index returned 7.2%, while the rest of the U.S. stock
market gained 19.2%.

       Top performers during the half-year were companies in computer software
and hardware, semiconductors, Internet-related businesses, and wireless
communications. Fully half of the 58 companies in the S&P 500's technology group
gained more than 50%, and the average return for tech stocks exceeded 39%. A
number of tech-related companies in the producer-durables sector also posted
impressive gains, and the sector as a whole returned 32%. A return of 34% was
achieved by the oil-drilling and services companies in the "other energy"
category, which benefited from higher oil and gas prices. The worst-performing
sector was consumer staples (-18%), a category that includes supermarket, food,
beverage, and tobacco stocks. Next in line were financial-services companies
(-7%), hurt by higher short-term interest rates, which tend to raise borrowing
costs for banks and can lead to increased loan defaults.

U.S. BOND MARKETS

The Federal Reserve Board's three rate increases succeeded in elevating other
short-term rates. For example, yields of 3-month U.S. Treasury bills rose during
the half-year to 5.83%, an increase of 0.74 percentage point (74 basis points)
that virtually matched the Fed's target. However, long-term rates didn't move
nearly as far. The 10-year Treasury note rose just 19 basis points, to 6.21%, as
of April 30. And yields actually fell a bit for very long-term Treasury bonds, a
result of shrinking supply. Because of the federal government's budget surplus,
the U.S. Treasury decided to reduce issuance of new bonds and to buy back some
of its existing long-term bonds. As investors reacted, the yield of the 30-year
Treasury declined 20 basis points--from 6.16% to 5.96%--during the half-year.

       The result of higher short-term rates and relatively stable long-term
rates was an unusual inversion in the Treasury yield curve. Instead of the usual
upward-sloping curve--which shows yields increasing in tandem with
maturities--there was a pronounced drop-off. As of April 30, the yield of
30-year Treasuries was two-thirds of a percentage point below the 6.62% yield on
3-year Treasury notes.

       A similar pattern emerged outside the Treasury market, although long-term
yields remained above yields for short-term corporate, municipal, and
mortgage-backed securities. The overall bond market, as measured by the Lehman
Aggregate Bond Index, provided a 1.4% return, as an average price decline of
-2.0% offset most of a 3.4% income return.

INTERNATIONAL STOCK MARKETS

Despite declines in March and April, stock markets in Europe, Asia, and many
emerging markets produced strong half-year gains as investors responded to
improving global economic growth and a rise in corporate merger-and-acquisition
activity. However, many of the gains were slashed for U.S. investors as the
dollar gained strength against most other currencies. (Conversely, when the
dollar falls in value, returns from abroad are enhanced for U.S. investors.)

       In U.S.-dollar terms, the overall return from developed foreign markets
was a very solid 6.8%, as measured by the Morgan Stanley Capital International
Europe, Australasia, Far East Index. However, in local currencies, the EAFE
Index return was 16.4%.

       In Europe, an average 21.1% gain in local-currency terms was reduced to
8.4% for U.S. investors because of the dollar's strength. Stocks in the Pacific
region, which is dominated by Japan, returned 3.6% in dollars, less than half
the 7.5% gain in local currencies. The Select Emerging Markets Free Index
returned 12.3% in U.S. dollars, with the biggest gains in Turkey (+148%), Russia
(+123%), and Israel (+50%).

REPORT FROM THE ADVISER

In a period that was full of challenges, the various Vanguard municipal bond
funds all posted positive total returns for the six months ended April 30, the
first half of our fiscal year.

       When the period began in November, market participants were still
wondering what would happen to the world's computers as the date changed from
December 31, 1999, to January 1, 2000. The answer was nothing. With this
question disposed of, market participants were left to ponder other matters.

       The equity markets have been plagued with increased day-to-day
volatility. Large moves, up or down, in stock market indexes now seem to be a
matter of course, and the swings also appear more violent. The Dow Jones
Industrial Average rose to a record 11,723 in January, only to retreat to 9,796
in March. By April 30, the Dow had recovered to 10,734. But the Dow's path
looked placid next to that of the Nasdaq Composite Index. The Nasdaq began the
fiscal year at 2,968, soared to a record 5,049 in March, and then fell back to
3,861 by the end of April. From January 1 through April 30, the Dow declined in
value by -6.6% and the Nasdaq by -5.1%.

       The bond markets have focused on three significant forces that will
determine the future course of interest rates. First, the rate of growth of the
U.S. economy is a major concern for the Federal Reserve Board. Second, the
increased volatility of the stock market raises the possibility that investors
may shift assets from stocks to bonds. Finally, the U.S. Treasury Department has
announced a plan to repurchase some of the nation's outstanding bonds.

       The economy has been growing at a torrid rate. Gross domestic product
rose at a 7.3% annual rate in the final quarter of calendar 1999 and at a slower
but still very strong 5.4% pace in the first quarter of 2000. The fear is that
such rapid growth will cause inflation to increase, forcing the Fed to further
raise short-term interest rates. Inflation, as measured by the Consumer Price
Index (CPI), increased by an average of 0.2% per month in the first three months
of the fiscal year, then by 0.5% in February and 0.7% in March. The CPI stayed
level in April, which left investors wondering whether the February-March uptick
would be sustained or temporary. Adding to the uncertainty is that the cost of
oil rose sharply during the half-year, topping out above $33 a barrel in March.
The employment picture hasn't eased the market's anxiety either; the
unemployment rate has averaged just over 4% during the first half of the fiscal
year, and a relative scarcity of labor could drive up wage costs.

       The stock market's increased volatility has caused bond investors to
debate whether equity investors will become anxious and switch money to the bond
market as a haven. If this were to occur--and so far it hasn't--municipal bonds
would provide attractive tax-exempt yields as an alternative to stocks. Although
many stock funds have negative year-to-date returns, money is




                                       6

seeping out of municipal and taxable bond funds--a little over $400 million and
$700 million, respectively, since January.

       The third significant force in the bond market was the Treasury
Department's announcement in late January that it planned to buy back
outstanding long-term Treasury bonds. The high tax receipts generated by the
growing U.S. economy are fueling the repurchase program. Investors anticipate
that the government's repurchases will significantly reduce the supply of
outstanding long-term Treasuries, and so buyers have been acquiring them before
the supply shrinks.

       The municipal bond market followed the Treasury market's lead over the
past six months. Short-term interest rates have increased significantly--the
yield of an AAA-rated general obligation bond with a 2-year maturity rose
nearly 0.60 percentage point (60 basis points) during the half-year. A
similar-quality 10-year municipal bond has seen its yield rise just 11 basis
points. But yields have fallen for long-term munis: a 30-year AAA-rated general
obligation bond yielded 9 basis points less on April 30 (5.80%) than at the
start of the fiscal year (5.89%).

       During the half-year, municipals became more attractive relative to
Treasury bonds. As of April 30, investors in 30-year, AAA-rated general
obligation municipal bonds could earn 97% of the yield paid by a long-term
Treasury bond, even though interest from municipal bonds is generally exempt
from federal income tax while interest from Treasuries is not.

       The supply of newly issued municipal bonds was 29% lower during the first
four months of calendar 2000 than during the same period of 1999. Higher
interest rates have made local governments less eager to borrow, and the strong
economy has swelled tax receipts for most state and local governments, reducing
their need to borrow.

       The decrease in supply of newly issued bonds helped to offset the effect
of cash outflows from municipal bond mutual funds--a net $400 million in cash
departed from such funds in the first four months of 2000.

       Going forward, we will continue to maintain our low-cost, value-oriented
approach to investing. We believe that this approach will--as it has in the
past--provide shareholders with superior risk-adjusted returns over a long-term
investment horizon.

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.

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 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
(high, medium, or low).

LARGEST STATE CONCENTRATIONS. An indicator of diversification. The less
concentrated a fund's holdings of bonds, the less the fund will be hurt by any
financial problems in a single state or region.

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 (7 days for money market funds) 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
APRIL 30, 2000 (UNAUDITED)

The Statements of Net Assets, integral parts of the Financial Statements for
each of the Vanguard Municipal Bond Funds, are included as an insert to this
report.

STATEMENT OF OPERATIONS
This Statement shows interest earned by each fund during the reporting period,
and details the operating expenses charged to the fund. These expenses directly
reduce the amount of investment income available to pay to shareholders as
tax-exempt income dividends. This Statement also shows any Net Gain (Loss)
realized on the sale of investments, and the increase or decrease in the
Unrealized Appreciation (Depreciation) on investments during the period. If a
fund invested in futures contracts during the period, the results of these
investments are shown separately.

STATEMENT OF CHANGES IN NET ASSETS
This Statement shows how each fund's total net assets changed during the two
most recent reporting periods. The Operations section summarizes information
detailed in the Statement of Operations. Because the fund distributes its income
to shareholders each day, the amounts of Distributions--Net Investment Income
generally equal the net income earned as shown under the Operations section. The
amounts of Distributions--Realized Capital Gain may not match the capital gains
shown in the Operations section, because distributions are determined on a tax
basis and may be made in a period different from the one in which the gains were
realized on the financial statements. The Capital Share Transactions section
shows the amount shareholders invested in the fund, either by purchasing shares
or by reinvesting distributions, and the amounts redeemed. The corresponding
numbers of Shares Issued and Redeemed are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table summarizes each fund's investment results and distributions to
shareholders on a per-share basis. It also presents the fund's 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. Money market funds are not required to report a Portfolio Turnover
Rate.

NOTES TO FINANCIAL STATEMENTS

Vanguard Municipal Bond Funds comprise the Tax-Exempt Money Market, Short-Term
Tax- Exempt, Limited-Term Tax-Exempt, Intermediate-Term Tax-Exempt, Insured
Long-Term Tax-Exempt, Long-Term Tax-Exempt, and High-Yield Tax-Exempt Funds,
each of which is registered under the Investment Company Act of 1940 as a
diversified open-end investment company, or mutual fund. Each fund invests in
debt instruments of many municipal issuers; the issuers' abilities to meet their
obligations may be affected by economic and political developments in a specific
state or region. Effective in 1997, each fund's fiscal year changed from August
31 to October 31.

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: Tax-Exempt Money Market Fund: Investment securities
are valued at amortized cost, which approximates market value. Other funds:
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.

     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. FUTURES CONTRACTS: Each fund, except the Tax-Exempt Money Market Fund,
may use Municipal Bond Index, U.S. Treasury Bond, and U.S. Treasury Note futures
contracts to a limited extent, with the objectives of enhancing returns,
managing interest-rate risk, maintaining liquidity, diversifying credit risk,
and minimizing transaction costs. The funds may purchase or sell futures
contracts instead of bonds to take advantage of pricing differentials between
the futures contracts and the underlying bonds. The funds may also seek to take
advantage of price differences among bond market sectors by simultaneously
buying futures (or bonds) of one market sector and selling futures (or bonds) of
another sector. Futures contracts may also be used to simulate a fully invested
position in the underlying bonds while maintaining a cash balance for liquidity.
The primary risks associated with the use of futures contracts are imperfect
correlation between changes in market values of bonds held by the funds and the
prices of futures contracts, and the possibility of an illiquid market.

     Futures contracts are valued based upon their quoted daily settlement
prices. The aggregate principal amounts of the contracts are not recorded in the
financial statements. Fluctuations in the values of futures contracts are
recorded in the Statement of Net Assets as an asset (liability) and in the
Statement of Operations as unrealized appreciation (depreciation) until the
contracts are closed, when they are recorded as realized futures gains (losses).

     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
original issue discounts 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 each fund 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 April 30, 2000, the funds had contributed
capital to Vanguard (included in Other Assets) of:

The funds' Trustees and officers are also Directors and officers of Vanguard.

C. The funds' investment adviser may direct new issue purchases, subject to
obtaining the best price and execution, to underwriters who have agreed to
rebate or credit to the funds part of the underwriting fees generated. Such
rebates or credits are used solely to reduce the funds' management and

</TABLE>

     The Short-Term and Intermediate-Term Tax-Exempt Funds used a tax accounting
practice to apply $194,000 and $1,897,000, respectively, of the price of capital
shares redeemed to reduce capital gain distribution requirements for the year
ended October 31, 1999. Capital gains that were so offset have been reclassified
from accumulated net realized gains to paid in capital. After this reduction,
the Short-Term Tax-Exempt Fund had $258,000 of 1999 capital gains remaining, on
which the fund paid federal tax of $78,000 (included in Realized Net Loss)
during the six months ended April 30, 2000. The balance after tax of $180,000
has been reclassified from accumulated net realized gains to paid in capital.

     The following funds had realized losses through October 31, 1999, which are
deferred for tax purposes and reduce the amount of unrealized appreciation
(depreciation) on investment securities for tax purposes (see Note F).

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.

   The majority of Vanguard's board members are independent, meaning that they

activities of the funds.

the funds; monitoring fund operations, performance, and costs; reviewing

VANGUARD MUNICIPAL BOND FUNDS
STATEMENT OF NET ASSETS  -  APRIL 30, 2000 (UNAUDITED)

The Statement of Net Assets should be read in conjunction with the Statement of
Operations, Statement of Changes in Net Assets, Financial Highlights, and Notes
to Financial Statements, all of which appear in the accompanying report.

       This Statement provides a detailed list of each fund's municipal bond
holdings by state, including each security's market value on the last day of the
reporting period and information on credit enhancements such as insurance or
letters of credit. Other assets are added to, and liabilities are subtracted
from, the value of Total Municipal Bonds 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 on both a dollar and
per-share basis. 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 taxable 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.
