INVESTMENT OBJECTIVES AND POLICIES

Vanguard/Wellington Fund (the "Fund") is a diversified open-end investment
company, or mutual fund, that seeks to conserve capital and to provide moderate
long-term capital growth and moderate income.

  The Fund invests approximately 60% to 70% of its assets in dividend-paying
stocks of established, large and medium-size companies that, in the adviser's
opinion, are undervalued but whose prospects are improving. The remaining 30% to
40% of assets are invested primarily in high-quality, longer-term corporate
bonds with some exposure to U.S. Treasury, government agency, and
mortgage-backed bonds.

  IT IS IMPORTANT TO NOTE THAT THE FUND'S SHARES ARE NOT GUARANTEED OR INSURED
BY THE FDIC OR ANY OTHER AGENCY OF THE U.S. GOVERNMENT. AS WITH ANY INVESTMENT
IN STOCKS (WHICH ARE SUBJECT TO WIDE FLUCTUATIONS IN MARKET VALUE) AND BONDS
(WHICH ARE SENSITIVE TO CHANGES IN INTEREST RATES), YOU COULD LOSE MONEY BY
INVESTING IN THE FUND.


FEES AND EXPENSES

The Fund is offered on a no-load basis, which means that you pay no sales
commissions or 12b-1 marketing fees. You will, however, incur expenses for
investment advisory, management, administrative, and distribution services,
which are included in the expense ratio.


ADDITIONAL INFORMATION ABOUT THE FUND

A Statement of Additional Information (dated March 21, 1997) containing more
information about the Fund is, by reference, part of this prospectus and may be
obtained without charge by writing to Vanguard or by calling our Investor
Information Department at 1-800-662-7447.


WHY READING THIS PROSPECTUS IS IMPORTANT

This prospectus explains the objectives, risks, and strategies of
Vanguard/Wellington Fund. To highlight terms and concepts important to mutual
fund investors, we have provided "Plain Talk" explanations along the way.
Reading the prospectus will help you to decide whether the Fund is the right
investment for you. We suggest that you keep it for future reference.

These securities have not been approved or disapproved by the Securities and
Exchange Commission or any state securities commission, nor has the Securities
and Exchange Commission or any state commission passed upon the accuracy or
adequacy of this prospectus. Any representation to the contrary is a criminal
offense.

 FUND PROFILE                                        Vanguard/Wellington Fund


WHO SHOULD INVEST (Page 4)

- -   Investors seeking moderate long-term capital growth and moderate income.

- -   Investors willing to invest for the long term--at least five years.

WHO SHOULD NOT INVEST

- -   Investors seeking significant dividend income.

- -   Investors unwilling to accept significant share-price fluctuations.

RISKS OF THE FUND (Pages 4-9)

The Fund's total return will fluctuate within a wide range, so an investor could
lose money over short or even extended periods. The Fund is subject to -- among
other risks -- stock market risk (the chance that stock prices in general will
decline, sometimes suddenly and sharply) and interest rate risk (the chance that
bond prices will decline because of rising interest rates).

DIVIDENDS AND CAPITAL GAINS (Page 11)

Dividends are paid in March, June, September, and December. Capital gains, if
any, are paid in December. In participant accounts, all distributions are
automatically reinvested.

In evaluating past performance, remember that it is not indicative of future
performance and that returns from stocks before adjusting for inflation were
relatively high during the periods shown. Performance figures include the
reinvestment of any dividends and capital gains distributions. The returns shown
are net of expenses for the Fund, but they do not reflect income taxes an
investor would have incurred. The Composite Index is a theoretical portfolio,
incurring none of the advisory fees, operating expenses, and portfolio
transaction costs that are borne by an operating mutual fund. Note, too, that
both the return and principal value of an investment will fluctuate so that
investors' shares, when redeemed, may be worth more or less than their original
cost.

                            PLAIN TALK ABOUT

                             THE COSTS OF INVESTING

Costs are an important consideration in choosing a mutual fund. That's because
you, as a shareholder, pay the costs of operating a fund, plus any transaction
costs associated with buying, selling, or exchanging shares. These costs can
erode a substantial portion of the gross income or capital appreciation a fund
achieves. Even seemingly small differences in fund expenses can, over time, have
a dramatic impact on a fund's performance.




                                  PLAIN TALK ABOUT

                                   FUND EXPENSES

All mutual funds have operating expenses. These expenses, which are deducted
from a fund's gross income, are expressed as a percentage of the net assets of
the fund. Vanguard/Wellington Fund's expense ratio in fiscal year 1996 was
0.31%, or $3.10 per $1,000 of average net assets. The average balanced mutual
fund had expenses in 1996 of 1.32%, or $13.20 per $1,000 of average net assets,
according to Lipper Analytical Services, Inc., which reports on the mutual fund
industry.


FUND EXPENSES

The examples below are designed to help you understand the various costs you
would bear, directly or indirectly, as an investor in the Fund.

 As noted in this table, you do not pay fees of any kind when you buy, sell, or
exchange shares of the Fund:
<TABLE>
<CAPTION>
SHAREHOLDER TRANSACTION EXPENSES

<S>                                                   <C>
Sales Load Imposed on Purchases:                      None
Sales Load Imposed on Reinvested Dividends:           None
Redemption Fees:                                      None
Exchange Fees:                                        None
</TABLE>

  The next table illustrates the operating expenses that you would incur as a
shareholder of the Fund. These expenses are deducted from the Fund's income
before it is paid to you. Expenses include investment advisory fees as well as
the costs of maintaining accounts, administering the Fund, providing shareholder
services, and other activities. The expenses shown in the table are for the
fiscal year ended November 30, 1996.

 The following example illustrates the hypothetical expenses that you would
incur on a $1,000 investment over various periods. The example assumes (1) that
the Fund provides a return of 5% a year and (2) that you redeem your investment
at the end of each period.

 From time to time, the Vanguard funds advertise yield and total return figures.
Yield is an historical measure of dividend income, and total return is a measure
of past dividend income (assuming that it has been reinvested) plus capital
appreciation. Neither yield nor total return should be used to predict the
future performance of a fund.


                                PLAIN TALK ABOUT

                   HOW TO READ THE FINANCIAL HIGHLIGHTS TABLE

The Fund began fiscal 1996 with a net asset value (price) of $24.57 per share.
During the year, the Fund earned $1.02 per share from investment income
(interest and dividends) and $4.00 per share from investments that had
appreciated in value or that were sold for higher prices than the Fund paid for
them. Of those total earnings of $5.02 per share, $0.97 per share was returned
to shareholders in the form of dividend distributions, and $0.28 per share in
the form of capital gains distributions. The earnings ($5.02 per share) less
total distributions ($1.25 per share) resulted in a share price of $28.34 at the
end of the year, an increase of $3.77 per share (from $24.57 at the beginning of
the period to $28.34 at the end of the period). Assuming that the shareholder
had reinvested the distributions in the purchase of more shares, total return
from the Fund was 21.26% for the year.

  As of November 30, 1996, the Fund had $16.5 billion in net assets; an expense
ratio of 0.31% ($3.10 per $1,000 of net assets); and net investment income
amounting to 4.08% of its average net assets. It sold and replaced securities
valued at 30% of its total net assets.

                                 BALANCED FUNDS

Balanced funds are "middle-of-the-road" investments that seek to provide some
combination of growth, income, and conservation of capital by investing in a
mix of stocks, bonds, and/or money market instruments.  Because stocks and
bonds tend to move in different directions, balanced funds are able to use the
rewards from one type of investment to help offset the risks from another.

A WORD ABOUT RISK

This prospectus describes the risks you will face as an investor in
Vanguard/Wellington Fund. It is important to keep in mind one of the main axioms
of investing: the higher the risk of losing money, the higher the potential
reward. The reverse, also, is generally true: the lower the risk, the lower the
potential reward. However, as you consider an investment in Vanguard/Wellington
Fund, you should also take into account your personal tolerance for the daily
fluctuations of both the stock and bond markets.

  Look for the "warning flag" symbol [FLAG] throughout the prospectus. It is
used to mark detailed information about each type of risk that you, as a
shareholder of the Fund, will confront.


THE FUND'S OBJECTIVES

The Fund seeks to conserve capital and to provide moderate long-term capital
growth and moderate income. These objectives are not fundamental, which means
that they can be changed by the Fund's board of directors without shareholder
approval. However, before making any important change in its objectives, the
Fund will give shareholders 30-days notice, in writing.

[FLAG] BECAUSE OF THE SEVERAL TYPES OF RISK DESCRIBED ON THE FOLLOWING PAGES,
       YOUR INVESTMENT IN THE FUND, AS WITH ANY INVESTMENT IN STOCKS AND
       BONDS, COULD LOSE MONEY.


WHO SHOULD INVEST

The Fund may be a suitable investment for you if:

- -    You wish to add a balanced fund to your existing holdings, which could
     include other stock and bond--as well as money market and
     tax-exempt--investments.

- -    You are seeking moderate growth of your capital over the long term--at
     least five years--while, at the same time, conserving your capital as much
     as possible.

- -    You are seeking moderate income.

- -    You want a simple way to invest in a relatively fixed percentage of stocks
     and bonds.

 This Fund is not an appropriate investment if you are a market-timer. Investors
who engage in excessive in-and-out trading activity generate additional costs
that are borne by all of the Fund's shareholders. To minimize such costs, which
reduce the ultimate returns achieved by you and other shareholders, the Fund has
adopted the following policies:

                                       4
<PAGE>   9
- -    The Fund reserves the right to reject any purchase request--including
     exchanges from other Vanguard funds--that it regards as disruptive to the
     efficient management of the Fund. This could be because of the timing of
     the investment or because of a history of excessive trading by the
     investor.

- -    There is a limit on the number of times you can exchange into or out of the
     Fund (see "Redeeming Shares" in the INVESTING WITH VANGUARD section).

- -    The Fund reserves the right to stop offering shares at any time.


INVESTMENT STRATEGIES

This section explains how Vanguard/Wellington Fund's investment adviser pursues
the objectives of conservation of capital, moderate long-term capital growth,
and moderate current income. It also explains important risks--stock market
risk, interest rate risk, manager risk, and credit risk--faced by investors in
the Fund. Like the Fund's objectives, the adviser's investment strategies are
not fundamental and can be changed by the Fund's board of directors without
shareholder approval. However, before making any important change in its
strategies, the Fund will give shareholders 30-days notice, in writing.


MARKET EXPOSURE

STOCKS

Roughly two-thirds of the Fund's assets are invested in common stocks. At times,
the Fund may also invest in securities that are convertible into common stocks.

[FLAG]    THE FUND IS SUBJECT TO STOCK MARKET RISK, WHICH IS THE POSSIBILITY
          THAT STOCK PRICES OVERALL WILL DECLINE OVER SHORT OR EVEN EXTENDED
          PERIODS. STOCK MARKETS TEND TO MOVE IN CYCLES, WITH PERIODS OF RISING
          STOCK PRICES AND PERIODS OF FALLING STOCK PRICES.

 To illustrate the volatility of stock prices, the following table shows the
best, worst, and average total returns (dividend income plus change in market
value) for the U.S. stock market over various periods as measured by the
Standard & Poor's 500 Composite Stock Price Index, a widely used barometer of
stock market activity. Note that the returns shown do not include the costs of
buying and selling stocks or other expenses that a real-world investment
portfolio would incur. Note, also, how the gap between best and worst tends to
narrow over the long term.

PLAIN TALK ABOUT COSTS AND MARKET TIMING

Some investors try to profit from "market timing"-switching money into
investments when they expect prices to rise, and taking money out when they
expect the market to fall.  As money is shifted in and out, a fund incurs
expenses for buying and selling securities.  These costs are borne by all fund
shareholders, including long-term investors who do not generate the costs.
Therefore, the Fund discourages short-term trading by, among other things,
limiting the number of exchanges it permits.

                              BONDS AND INTEREST RATES

As a rule, when interest rates rise, bond prices fall. The opposite is also
true: Bond prices go up when interest rates fall. Why do bond prices and
interest rates move in opposite directions? Let's assume that you hold a bond
offering a 5% yield. A year later, interest rates are on the rise and bonds are
offered with a 6% yield. With higher-yielding bonds available, you would have
trouble selling your 5% bond for the price you paid--causing you to lower your
asking price. On the other hand, if interest rates were falling and 4% bonds
were being offered, you would be able to sell your 5% bond for more than you
paid.


                                  PLAIN TALK ABOUT

                                  BOND MATURITIES

A bond is issued with a specific maturity date--the date when the bond's issuer,
or seller, must pay back the bond's initial value (known as its "face value").
Bond maturities generally range from less than one year (short term) to 30 years
(long term). The longer a bond's maturity, the more risk you, as a bond
investor, face as interest rates rise--but also the more interest you could
receive. Long-term bonds are more suitable for investors willing to take greater
risks in hope of higher yields; short-term bond investors should be willing to
accept lower yields in return for less fluctuation in the value of their
investment.

</TABLE>

 The table covers all of the 1-, 5-, 10-, and 20-year periods from 1926 through
1996. For example, while the average return on stocks for all of the 5-year
periods was 10.4%, returns for these 5-year periods ranged from a -12.5% average
(from 1928 through 1932), to 23.9% (from 1950 through 1954). These average
returns reflect past performance on common stocks and should not be regarded as
an indication of future returns from either the stock market as a whole or this
Fund in particular.

  Finally, because Vanguard/Wellington Fund does not hold the same securities
held in the S&P 500 Index or any other market index, the performance of the Fund
will not mirror the returns of any particular index.

BONDS

Approximately one-third of the Fund's assets are invested in bonds.

[FLAG]    The Fund is subject to interest rate risk, which is the possibility
          that bond prices overall will decline over short, or even extended,
          periods due to rising interest rates. Interest rate risk should be
          modest for shorter-term bonds and high for longer-term bonds.

 Although bonds are often thought to be less risky than stocks, there have been
periods when bond values have fallen significantly due to rising interest rates.
For instance, prices of long-term bonds fell by almost 48% between December 1976
and September 1981.

 To illustrate the relationship between bond prices and interest rates, the
following table shows the impact of a 2% change (both up and down) in interest
rates on three $1,000 bonds, each with a different maturity.

  Finally, because stock and bond prices often move in different directions, the
Fund's bond holdings help to dampen--but not eliminate--some of the stock market
volatility experienced by the Fund. Likewise, changes in interest rates may not
have as dramatic an effect on Wellington Fund as they would on a fund made up
entirely of bonds.


SECURITY SELECTION

Wellington Management Company, LLP (WMC), adviser to the Fund, invests
approximately 60% to 70% of the Fund's assets in dividend-paying common stocks
and the remaining 30% to 40% of assets in high-quality bonds. While the mix of
stocks and bonds varies from time to time depending on the adviser's views of
economic and market conditions, the stock portion can be expected to represent
at least 60% of the Fund's holdings.

 The Fund is run by WMC according to traditional methods of active investment
management. Securities are bought and sold based on WMC's judgments about
companies and their financial prospects, and about bond issuers and the general
level of interest rates. To achieve the Fund's objectives of conservation of
capital, moderate long-term growth, and moderate income, the adviser follows
specific strategies for stock selection and bond selection.

[FLAG]    THE FUND IS SUBJECT TO MANAGER RISK, WHICH IS THE POSSIBILITY THAT WMC
          MAY DO A POOR JOB OF SELECTING STOCKS AND BONDS.


STOCKS

WMC uses extensive research to find what it considers to be undervalued stocks
of established, large- and medium-size companies. WMC considers a stock to be
undervalued if company earnings, or potential earnings, are not fully reflected
in the stock's share price. In other words, the current prices of these large-
and mid-cap stocks may be less than what the adviser thinks they are truly
worth.

 The adviser's goal is to identify and purchase these securities before their
value is recognized by other investors. The adviser emphasizes stocks that, on
average, provide a higher level of dividend income than stocks in the overall
market generally provide. By adhering to this stock selection strategy and by
investing in a wide variety of companies and industries, the adviser expects to
moderate overall risk.

 The Fund's top ten stock holdings (which amounted to 16% of the Fund's net
assets) as of November 30, 1996, follow.

   1. General Electric Co.
   2. Allstate Corp.
   3. Citicorp
   4. First Bank System, Inc.

                    LARGE-CAP, MID-CAP, AND SMALL-CAP STOCKS

Stocks of publicly traded companies--and mutual funds that hold these
stocks--can be classified by the companies' market value, or capitalization.
Vanguard defines large-capitalization, or large-cap, funds as those holding
stocks of companies with a median market value of their outstanding shares
exceeding $5 billion. Mid-cap funds hold stocks of companies with a median
market value between $1 billion and $5 billion. Small-cap funds hold stocks of
companies with a median market value of less than $1 billion. Historically,
large-cap funds have exhibited lower volatility than mid-cap and small-cap
funds.

                                 TYPES OF BONDS

Bonds are issued (sold) by many sources: corporations issue corporate bonds; the
federal government issues U.S. Treasury bonds; agencies of the federal
government issue agency bonds; and mortgage holders issue "mortgage-backed"
bonds such as Government National Mortgage Association (GNMA). Each issuer is
responsible for paying back the bond's initial value as well as periodic
interest payments.


                                PLAIN TALK ABOUT

                                 CREDIT QUALITY

A bond's credit quality depends on the issuer's ability to pay interest on the
bond and, ultimately, to repay the debt. The lower the rating by one of the
independent bond-rating agencies (for example, Moody's or Standard & Poor's),
the greater the chance (in the rating agency's opinion) that the bond issuer
will default, or fail to meet its payment obligations. All things being equal,
the lower a bond's credit rating, the higher the yield the bond seeks to pay (as
compensation for the risks an investor must take).

                                 PORTFOLIO TURNOVER

Before investing in a mutual fund, you should review its portfolio turnover rate
for an indication of the potential effect of transaction costs on the fund's
future returns. In general, the greater the volume of buying and selling by the
fund, the greater the impact that brokerage commissions and other transaction
costs will have on its return. Also, funds with high portfolio turnover rates
may be more likely than low-turnover funds to generate capital gains that must
be distributed to shareholders as taxable income. The average turnover rate for
actively managed balanced funds is 86%.

Keep in mind that, because the stock makeup of the Fund changes daily, this
listing is only a "snapshot" at one point in time.

BONDS

WMC selects high-quality bonds that, it believes, will generate a high and
sustainable level of income. These bonds would include intermediate- and
long-term corporate bonds, U.S. Treasury, government agency, and mortgage-backed
and asset-backed bonds.

 A breakdown of the Fund's bond holdings (which amounted to 34% of the Fund's
total net assets) as of November 30, 1996, follows.

[FLAG]    THE FUND IS SUBJECT, TO A LIMITED EXTENT, TO CREDIT RISK, WHICH IS THE
          POSSIBILITY THAT A BOND ISSUER WILL FAIL TO REPAY INTEREST AND
          PRINCIPAL IN A TIMELY MANNER.

 WMC purchases bonds that are primarily investment-grade quality--that is, the
bonds are rated at least Baa by Moody's Investors Service, Inc., or BBB by
Standard & Poor's Corporation. The average quality of bonds held by the Fund, as
of November 30, 1996, was Aa2, according to Moody's.

 The U.S. government guarantees the timely payment of interest and principal for
its Treasury bonds, but does not guarantee its bonds' prices. In other words,
while the Treasury bonds enjoy the highest credit ratings, their prices--like
the prices of other bonds in the Fund--will fluctuate with changes in interest
rates.


PORTFOLIO TURNOVER

Although the Fund generally seeks to invest for the long term, it retains the
right to sell securities regardless of how long they have been held. It is not
expected that the Fund's turnover rate would exceed 50% in the future. (A
turnover rate of 100% would occur, for example, if the Fund sold and replaced
securities valued at 100% of its total net assets within a one-year period.)


INVESTMENT POLICIES

Besides investing in stocks of large and medium-size companies and high-quality
intermediate- and long-term bonds issued by corporations, the U.S. government,
and its agencies, the Fund may follow a number of investment policies to achieve
its objectives.

                                       8
<PAGE>   13
 Up to 15% of the Fund's assets may be invested in the common stocks of foreign
companies as well as securities that are convertible into foreign stocks. The
Fund may engage in currency transactions with respect to these securities. The
Fund may also invest in fixed-income securities issued by foreign governments
and non-U.S.-based companies; however, these securities must be valued in U.S.
dollars and meet the Fund's credit quality standards. Over the years, the prices
of foreign investments and the prices of U.S. investments have often moved in
different directions. In addition, international markets operate differently
from U.S. markets. For instance, foreign exchanges, brokers, and companies
generally have less government supervision and regulation than in the U.S.

 The Fund may invest up to 15% of its assets in restricted securities with
limited marketability or other illiquid securities.

 The Fund may also invest in derivatives.

[FLAG] THE FUND RESERVES THE RIGHT TO INVEST, TO A LIMITED EXTENT, IN STOCK AND
       BOND (INTEREST RATE) FUTURES AND OPTIONS CONTRACTS, WHICH ARE TRADITIONAL
       TYPES OF DERIVATIVES. THE FUND MAY ALSO INVEST MODESTLY IN LESS RISKY
       CLASSES OF COLLATERALIZED MORTGAGE OBLIGATIONS (CMOs). 

 Losses (or gains) involving futures can sometimes be substantial--in part
because a relatively small price movement in a futures contract may result in an
immediate and substantial loss (or gain) for a Fund. This Fund will not use
futures and options for speculative purposes or as leveraged investments that
magnify the gains or losses of an investment. If it holds futures and options,
the Fund will keep separate cash reserves or short-term cash-equivalent
securities in the amount of the obligation underlying the futures contract. Only
a limited percentage of the Fund's assets--up to 5% if required for deposit and
no more than 20% of total assets--may be committed to such contracts.

 The reasons for which the Fund may use futures and options are:

- -    To keep cash on hand to meet shareholder redemptions or other needs while
     simulating full investment in stocks and bonds.

- -    To make it easier to trade.

- -    To reduce costs by buying futures instead of actual stocks or bonds when
     futures are cheaper.

 Please see the Statement of Additional Information for a more detailed
discussion of the Fund's investments in derivatives. The Fund will usually hold
only a small percentage of its assets in cash reserves, although if the
investment adviser believes that market conditions warrant a temporary defensive
measure, the Fund may hold cash reserves without limit.


INVESTMENT LIMITATIONS

To reduce risk and maintain diversification, the Fund has adopted limits on some
of its investment policies. Specifically, the Fund will not:

                                  DERIVATIVES

A derivative is a financial contract whose value is based on (or "derived"
from) a traditional security (such as a stock or a bond), an asset (such as a
commodity like gold), or a market index (such as the S&P 500 Index). Futures
and options are derivatives that have been trading on regulated exchanges for
more than two decades. These "traditional" derivatives are standardized
contracts that can easily be bought and sold, and whose market values are
determined and published daily. It is these characteristics that differentiate
futures and options from the relatively new, exotic types of derivatives -- some
of which can carry considerable risks.

                                  PAST PERFORMANCE

Whenever you see information on a fund's performance, do not consider the
figures to be an indication of the performance you could expect by making an
investment in the fund today. The past is an imperfect guide to the future;
history does not repeat itself in neat, predictable patterns.


- -    Invest more than 5% of its assets in the securities of companies that have
     been in business for less than three years.

- -    Invest more than 25% of its assets in any one industry.

- -    Borrow money, except for the purpose of meeting shareholder requests to
     redeem shares. Amounts borrowed will not exceed 10% of the Fund's net
     assets.
    
     With respect to 75% of its assets, this Fund will not:

- -    Invest more than 5% in the securities of any one company.

- -    Buy more than 10% of the outstanding voting securities of any company.

 The limitations listed in this prospectus and in the Statement of Additional
Information are fundamental and may be changed only by approval of a majority of
the Fund's shareholders.


INVESTMENT PERFORMANCE

As a balanced fund, Vanguard/Wellington Fund invests primarily in stocks, with a
sizable holding of bonds--so Fund performance is closely tied to both the stock
and bond markets. Historically, stock market performance has been characterized
by sharp up-and-down swings in the short term, and by more stable growth over
the long term. Bond market performance has been--and remains--strongly
influenced by changes in interest rates.

                                  [BAR GRAPH]



 The results shown represent the Fund's "average annual total return"
performance, which assumes that any distributions of capital gains and dividends
were reinvested for the indicated periods. Also included is comparative
information on an unmanaged "composite index" of 65% stocks and 35% bonds. The
Standard & Poor's 500 Composite Stock Price Index represents the stock portion
of the composite index, while the Lehman Brothers Long-Term Corporate AA or
Better Bond Index makes up the bond portion. The chart does not make any
allowance for federal, state, or local income taxes that shareholders must pay
on a current basis.

                                 DISTRIBUTIONS

As a shareholder, you are entitled to your share of the fund's income from
interest and dividends, and gains from the sale of investments. You receive such
earnings as either an income dividend or capital gains distribution. Income
dividends come from interest the fund earns from its money market and bond
investments as well as dividends it receives from its stock investments.
Capital gains are realized whenever the fund sells securities for higher prices
than it paid for them. These capital gains are either short-term or long-term
depending on whether the fund held the securities for less than or more than
one year.

                                PLAIN TALK ABOUT

                              "BUYING A DIVIDEND"

Unless you are investing in a tax-deferred retirement account (such as an IRA),
it is not to your advantage to buy shares of a fund shortly before it makes a
distribution, because part of your investment will come back to you as a
taxable distribution. This is known as "buying a dividend." For example: On
December 15, you invest $5,000, buying 250 shares for $20 each. If the fund pays
a distribution of $1 per share on December 16, its share price would drop to
$19 (not counting market change). You would still only have $5,000 (250 shares
x $19 = $4,750 in share value, plus 250 shares x $1 = $250 in distributions),
but you would owe tax on the $250 distribution you received, even if you had
reinvested the dividends in more shares. To avoid "buying a dividend," check a
fund's distribution schedule before you invest.

SHARE PRICE

The Fund's share price, called its net asset value, is calculated each business
day after the close of trading (generally 4 p.m. Eastern time) of the New York
Stock Exchange. Net asset value per share is calculated by adding up the total
assets of the Fund, subtracting all of its liabilities, or debts, and then
dividing by the total number of Fund shares outstanding:

                                TOTAL ASSETS  -  LIABILITIES
  NET ASSET VALUE  =      ----------------------------------------
                                NUMBER OF SHARES OUTSTANDING

     The daily net asset value, or NAV, is useful to you as a shareholder
because the NAV, multiplied by the number of Fund shares you own, gives you the
dollar amount you would have received had you sold all of your shares back to
the Fund that day.

     The Fund's share price can be found daily in the mutual fund listings of
most major newspapers under the heading Vanguard Group. Different newspapers use
different abbreviations of the Fund's name, but the most common is WELLTN.


DIVIDENDS, CAPITAL GAINS, AND TAXES

Each March, June, September, and December, the Fund distributes to shareholders
virtually all of its income from interest and dividends. Any capital gains
realized from the sale of securities are distributed in December. Your
distributions of income and capital gains are automatically invested in more
shares of the Fund unless you elect to receive the distributions in cash. In
either case, distributions of dividends and capital gains that are declared in
December--even if paid to you in January--are taxed as if they had been paid
to you in December. Vanguard will process your dividend distribution and send
you a statement each year showing the tax status of all your distributions.

[ ] The dividends and short-term capital gains that you receive are taxable to
    you as ordinary income. Any distributions of net long-term capital gains by
    the Fund are taxable to you as long-term capital gains, no matter how long
    you've owned shares in the Fund. Both dividend and capital gains
    distributions are taxable to you whether received in cash or reinvested in
    additional shares. Although the Fund does not seek to realize any particular
    amount of capital gains during a year, such gains are realized from time to
    time as byproducts of the ordinary investment activities of the Fund.
    Consequently, distributions may vary considerably from year to year.

[ ] If you sell or exchange shares, any gain or loss you have is a taxable
    event, which means you may have a capital gain to report as income, or a
    capital loss to report as a deduction, when you complete your federal income
    tax return.

                       VANGUARD'S UNIQUE CORPORATE STRUCTURE

The Vanguard Group, Inc. is the only mutual mutual fund company. It is owned
jointly by the funds it oversees and by the shareholders in those funds. Other
mutual funds are operated by for-profit management companies that may be owned
by one person, by a group of individuals, or by investors who bought the
management company's publicly traded stock. Because of its structure, Vanguard
operates its funds at cost. Instead of distributing profits from operations to a
separate management company, Vanguard returns profits to fund shareholders in
the form of lower operating expenses.


                                  PLAIN TALK ABOUT

                                 THE FUND'S ADVISER

Wellington Management Company, LLP (WMC), an investment advisory firm founded in
1933, currently manages more than $133 billion in stock and bond portfolios,
including 13 Vanguard funds. The managers responsible for overseeing
Vanguard/Wellington Fund are:

  ERNST H. VON METZSCH, CFA, Senior Vice President of WMC; 27 years investment
experience, 24 years with WMC; M.Sc. from The University of Leiden, The
Netherlands, Ph.D. from Harvard University.

  PAUL D. KAPLAN, Senior Vice President of WMC; 23 years investment experience,
19 years with WMC; B.S. from Dickinson College, M.S. from The Sloan School of
Management, Massachusetts Institute of Technology.

[] Distributions of dividends or capital gains, and capital gains or losses from
   your sale or exchange of Fund shares, may be subject to state and local
   income taxes as well.

   The tax information in this prospectus is provided as general information
and will not apply to you if you are investing in a tax-deferred account such
as an IRA. You should consult your own tax adviser about the tax consequences
of an investment in the Fund.

THE FUND AND VANGUARD

The Fund is a member of The Vanguard Group, a family of more than 30 investment
companies with more than 90 distinct investment portfolios and total net assets
of more than $250 billion. All of the Vanguard Funds share in the expenses
associated with business operations, such as personnel, office space, equipment,
and advertising.

 Vanguard also provides marketing services to the funds. Although shareholders
do not pay sales commissions or 12b-1 marketing fees, each fund pays its
allocated share of The Vanguard Group's costs.

 A list of the Fund's directors and officers, and their present positions and
principal occupations during the past five years, can be found in the Statement
of Additional Information.


INVESTMENT ADVISER

The Fund employs Wellington Management Company, LLP (WMC), 75 State Street,
Boston, MA 02109, as its investment adviser. WMC manages the Fund subject to the
control of the officers and directors of the Fund.

 Each quarter, WMC is paid an advisory fee based on average month-end net assets
of the Fund and a sliding percentage scale:
<TABLE>
<CAPTION>
           ASSETS MANAGED                     FEE

<S>                                          <C>
           First $1 billion                  0.10%
           Next $2 billion                   0.05
           Next $7 billion                   0.04
           Assets over $10 billion           0.03
</TABLE>

 The advisory fee can be increased or decreased based on the difference between
the Fund's total return performance and that of an unmanaged "composite index,"
which is made up of the S&P 500 Index (65% of the composite index) and Lehman
Brothers Long- Term Corporate AA or Better Bond Index (35% of the composite
index). Under the fee schedule, the base fee may be increased or decreased by up
to 30%. The incentive/penalty fee will not be in full operation until the
quarter ending May 31, 1999. Until that date, the incentive/penalty fee will be
calculated using certain transition rules that are explained in the Statement of
Additional Information.

                                       12
<PAGE>   17
   For the year ended November 30, 1996, the investment advisory fee paid to WMC
was $6.12 million.

   The agreement authorizes WMC to choose brokers or dealers to handle the
purchase and sale of the Fund's securities, and directs
WMC to get the best available price and most favorable execution from these
brokers with respect to all transactions. At times, WMC may choose brokers who
charge higher commissions in the interest of obtaining better execution of a
transaction. If more than one broker can obtain the best available price and
favorable execution of a transaction, then WMC is authorized to choose a broker
who, in addition to executing the transaction, will provide research services to
WMC or the Fund. However, WMC will not pay higher commissions specifically for
the purpose of obtaining research services. The Fund may direct WMC to use a
particular broker for certain transactions in exchange for commission rebates or
research services provided to the Fund.

   The board of directors may, without prior approval from shareholders, change
the terms of the advisory agreement or hire a new investment adviser, either as
a replacement for WMC or as an additional adviser. However, no such change would
be made before giving shareholders 30-days notice, in writing.


GENERAL INFORMATION

Vanguard/Wellington Fund is a corporation organized under the laws of the state
of Maryland. Shareholders of the Fund have rights and privileges similar to
those enjoyed by other corporate shareholders. For example, shareholders will
not be responsible for any liabilities of the corporation. If any matters are to
be voted on by shareholders (such as the election of directors), each share
outstanding at that point would be entitled to one vote. Annual meetings will
not be held by the Fund except as required by the Investment Company Act of
1940. A meeting will be scheduled if the holders of at least 10% of the Fund's
shares request a meeting in writing.

                                               Account Features."



You can redeem (that is, sell or exchange) shares purchased by check or Vanguard
Fund Express at any time. However, while your redemption request will be
processed at the next-determined net asset value after it is received, your
redemption proceeds will not be available until payment for your purchase is
collected, which may take up to ten days.

NOTE: If you buy Fund shares through a registered broker-dealer or investment
adviser, the broker-dealer or adviser may charge you a service fee.


  It is important that you call Vanguard before you invest a large dollar amount
by wire or check. We must consider the interests of all Fund shareholders and so
reserve the right to delay or refuse any purchase that will disrupt the Fund's
operation or performance.


REDEEMING SHARES 

IMPORTANT TAX NOTE: Any sale or exchange of shares in a non-retirement account
could result in a taxable gain or a loss.

The ability to redeem (that is, sell or exchange) Fund shares by telephone is
automatically established for your account unless you tell us in writing that
you do not want this option.

  To protect your account from unauthorized or fraudulent telephone
instructions, Vanguard follows specific security procedures. When we receive a
call requesting an account transaction, we require the caller to provide:

- -    Fund name.

- -    10-digit account number.

- -    Name and address exactly as registered on that account.

- -    Social Security or Employer Identification number as registered on that
     account.

  If you call to sell shares, the sale proceeds will be made payable to you, as
the registered shareholder, and mailed to your account's address of record.

  If we follow reasonable security procedures, neither the Fund nor Vanguard
will be responsible for the authenticity of transaction instructions received by
telephone. We believe that these procedures are reasonable and that, if we
follow them, you bear the risk of any losses resulting from unauthorized or
fraudulent telephone transactions on your account.

HOW TO SELL SHARES

You may withdraw any part of your account, at any time, by selling shares. Sale
proceeds are normally mailed within two business days after Vanguard receives
your request. The sale price of your shares will be the Fund's next-determined
net asset value after Vanguard receives all required documents in good order.


                                       18
<PAGE>   24
REDEEMING SHARES (continued)

    Good order means that the request includes:

check mark    Fund name and account number.

check mark    Amount of the transaction (in dollars or shares).

check mark    Signatures of all owners exactly as registered on the account.

check mark    Signature guarantees (if required).

check mark    Any supporting legal documentation that may be required.

check mark    Any certificates you are holding for the account.

  Sales or exchange requests received after the close of trading on the New York
Stock Exchange (generally 4 p.m. Eastern time) are processed at the next
business day's net asset value.

  The Fund reserves the right to close any non-retirement or UGMA/UTMA account
whose balance falls below the minimum initial investment. The Fund will deduct a
$10 annual fee if your non-retirement account balance falls below $2,500 or if
your UGMA/UTMA account balance falls below $500. The fee is waived if your total
Vanguard account assets are $50,000 or more.

Some written requests require a signature guarantee from a bank, broker, or
other acceptable institution. A notary public cannot provide a signature
guarantee.


HOW TO EXCHANGE SHARES

An exchange is the selling of shares of one Vanguard fund to purchase shares of
another.

  Although we make every effort to maintain the exchange privilege, Vanguard
reserves the right to revise or terminate the exchange privilege, limit the
amount of an exchange, or reject any exchange, at any time, without notice.

  Because excessive exchanges can potentially disrupt the management of the Fund
and increase transaction costs, Vanguard limits exchange activity to two
SUBSTANTIVE EXCHANGE REDEMPTIONS (at least 30 days apart) from the Fund during
any 12-month period. "Substantive" means either a dollar amount large enough to
have a negative impact on the Fund or a series of movements between Vanguard
funds.

  Before you exchange into a new Vanguard fund, be sure to read its prospectus.

Information.

  It is important that you call Vanguard before you redeem a large dollar
amount. We must consider the interests of all Fund shareholders and so reserve
the right to delay your redemption proceeds -- up to seven days -- if the amount
will disrupt the Fund's operation or performance.


                    A NOTE ON UNUSUAL CIRCUMSTANCES

 Vanguard reserves the right to revise or terminate the telephone redemption
privilege at any time, without notice. In addition, Vanguard can stop selling
shares or postpone payment at times when the New York Stock Exchange is closed
or under any emergency circumstances as determined by the United States
Securities and Exchange Commission. If you experience difficulty making a
telephone redemption during periods of drastic economic or market change, you
can send us your request by regular or express mail. Follow the instructions on
selling or exchanging shares by mail in the "Redeeming Shares" section.

Knowing your risk tolerance is important when you are making an investment
decision. To give you a general idea of your comfort level with investing,
circle the response that most closely matches your personal situation. Keep in
mind, though, that there is no "foolproof" way to accurately gauge your risk
tolerance. Scoring for the quiz is below.


                         HOW TO SCORE THE QUIZ

Use the number of your answer as the number of points scored. For instance, if
you chose answer #3 to a question, that's worth three points. Add up your points
and check below for the type of investor you are. (Note: If you chose answer #1
or #2 to Question C, subtract five points from your total score.)

- -    If you scored between 0 and 25 points, you are considered a conservative
     investor.

- -    If you scored between 26 and 32 points, you are considered a moderate
     investor.

- -    If you scored between 33 and 35 points, you are considered an aggressive
     investor.

AN INVESTMENT PRIMER

Whether you are investing for the short or long term, keep these three points in
mind:

1.    INVEST IN ALL THREE OF THE MAJOR ASSET CLASSES.

Most people use a combination of . . .

- -    Stocks, which are considered the "riskiest" of the three asset classes. Day
     to day, or even year to year, stocks tend to have wide price swings.
     Despite this potential for significant price fluctuation, however, stocks
     have historically offered higher returns than the other major asset classes
     over longer periods.

- -    Bonds, which are chiefly influenced by changes in interest rates. When
     interest rates climb, bond prices drop; when interest rates fall, bond
     prices rise.

- -    Cash reserves, which offer more share-price (or capital) stability than
     stocks or bonds -- but also generate lower returns. Some examples are
     Treasury bills and money market funds.


2.    REMEMBER THAT SAFETY HAS A PRICE.

Many people want a "no-risk" investment. Remember, though, that the more safety
you seek, the less potential reward you can expect -- and the less you can
expect in returns after inflation. Inflation affects not only the price you pay
for goods and services; it also eats away at your investment returns over time.
What is left is known as your "real" return -- the actual return you receive
after you factor in inflation (see the chart at left).

3.    CHANCES ARE GOOD THAT YOU CAN AFFORD TO TAKE MORE RISK.

As the chart shows, inflation cuts into the returns of all three asset classes.
However, stocks and bonds have had an easier time of outpacing inflation over
time -- which means that, to beat inflation, you may need to invest more
aggressively.

  Don't be put off by potential downswings in the value of your investment,
especially if you are investing for long periods. Time acts as a shock absorber,
letting you ride out the short-term bumps that investments often provide. The
longer you hold an investment, the more likely it is that you will earn a
positive return.

GLOSSARY OF INVESTMENT TERMS


BALANCED FUND

A mutual fund that seeks to provide some combination of income, capital growth,
and conservation of capital by investing in stocks, bonds, and/or money market
instruments.


BOND

A debt security (IOU) issued by a corporation, government, or government agency
in exchange for the money you lend it. In most instances, the issuer agrees to
pay back the loan by a specific date and make regular interest payments until
that date.


CAPITAL GAINS DISTRIBUTION

Payment to mutual fund shareholders of gains realized during the year on
securities that the fund has sold at a profit, minus any realized losses.


CASH RESERVES

Cash deposits as well as short-term bank deposits, money market instruments,
U.S. Treasury bills, commercial paper, and banker's acceptances.


COMMON STOCK

A security representing ownership rights in a corporation. A stockholder is
entitled to share in the company's profits, some of which may be paid out as
dividends.


CREDIT QUALITY

A measure of a bond issuer's ability to repay interest and principal in a timely
manner.


DIVIDEND INCOME

Payment to shareholders of income from interest or dividends generated by a
fund's investments.


EXPENSE RATIO

The percentage of a fund's average net assets used to pay its expenses. The
expense ratio includes management fees, administrative fees, and any 12b-1
marketing fees.


FACE VALUE

The value of a bond at the time it was issued (that is, initially sold).


FIXED-INCOME SECURITIES

Investments, such as bonds, that have a fixed payment schedule. While the level
of income offered by these securities is predetermined, their prices may
fluctuate.


INVESTMENT GRADE

Bonds whose credit quality is considered to be among the highest by independent
bond-rating agencies.


MATURITY

The date when a bond issuer agrees to repay the bond's principal, or face value,
to the bond's buyer.


MUTUAL FUND

An investment company that pools the money of many people and invests it in a
variety of securities in an effort to achieve a specific objective over time.


NET ASSET VALUE (NAV)

The market value of a mutual fund's total assets, minus liabilities, divided by
the number of shares outstanding. The value of a single share is called its
share value or share price.


PORTFOLIO DIVERSIFICATION

Holding a variety of securities so that a portfolio's return is not hurt by the
poor performance of a single security or industry.


PRICE/EARNINGS (P/E) RATIO

The current share price of a stock, divided by its per-share earnings (profits)
from the past year. A stock selling for $20, with earnings of $2 per share, has
a price/earnings ratio of 10.


TOTAL RETURN

A percentage change, over a specified time period, in a mutual fund's net asset
value, with the ending net asset value adjusted to account for the reinvestment
of all distributions of dividends and capital gains.


VOLATILITY

The fluctuations in value of a mutual fund or other security. The greater a
fund's volatility, the wider the fluctuations between its high and low prices.


YIELD

Current income (interest or dividends) earned by an investment, expressed as a
percentage of the investment's price.

INVESTMENT OBJECTIVES AND POLICIES

Vanguard/Wellington Fund (the "Fund") is a diversified open-end investment
company, or mutual fund, that seeks to conserve capital and to provide moderate
long-term capital growth and moderate income.

         The Fund invests approximately 60% to 70% of its assets in
dividend-paying stocks of established, large and medium-size companies that, in
the adviser's opinion, are undervalued but whose prospects are improving. The
remaining 30% to 40% of assets are invested primarily in high-quality,
longer-term corporate bonds with some exposure to U.S. Treasury, government
agency, and mortgage-backed bonds.

         IT IS IMPORTANT TO NOTE THAT THE FUND'S SHARES ARE NOT GUARANTEED OR
INSURED BY THE FDIC OR ANY OTHER AGENCY OF THE U.S. GOVERNMENT. AS WITH ANY
INVESTMENT IN STOCKS (WHICH ARE SUBJECT TO WIDE FLUCTUATIONS IN MARKET VALUE)
AND BONDS (WHICH ARE SENSITIVE TO CHANGES IN INTEREST RATES), YOU COULD LOSE
MONEY BY INVESTING IN THE FUND.

FEES AND EXPENSES

The Fund is offered on a no-load basis, which means that you pay no sales
commissions or 12b-1 marketing fees. You will, however, incur expenses for
investment advisory, management, administrative, and distribution services,
which are included in the expense ratio.

IMPORTANT NOTE

This prospectus is intended for institutional clients and for participants in
employer-sponsored retirement or savings plans. Another version -- for investors
who would like to open a personal investment account -- can be obtained by
calling Vanguard at 1-800-662-7447.

ADDITIONAL INFORMATION ABOUT THE FUND

A Statement of Additional Information (dated March 21, 1997) containing more
information about the Fund is, by reference, part of this prospectus and may be
obtained without charge by contacting Vanguard (see back cover).

WHY READING THIS PROSPECTUS IS IMPORTANT

This prospectus explains the objectives, risks, and strategies of
Vanguard/Wellington Fund. To highlight terms and concepts important to mutual
fund investors, we have provided "Plain Talk" explanations along the way.
Reading the prospectus will help you to decide whether the Fund is the right
investment for your needs. We suggest that you keep it for future reference.

FUND PROFILE                                            Vanguard/Wellington Fund



WHO SHOULD INVEST (page 4)

- -  Investors seeking moderate long-term capital growth and moderate income.

- -  Investors willing to invest for the long term -- at least five years.

WHO SHOULD NOT INVEST

- -  Investors seeking significant dividend income.

- -  Investors unwilling to accept significant share-price fluctuations.

RISKS OF THE FUND (pages 4 - 9)

The Fund's total return will fluctuate within a wide range, so an investor could
lose money over short or even extended periods. The Fund is subject to -- among
other risks -- stock market risk (the chance that stock prices in general will
decline, sometimes suddenly and sharply) and interest rate risk (the chance that
bond prices will decline because of rising interest rates).

DIVIDENDS AND CAPITAL GAINS (page 11)

Dividends are paid in March, June, September, and December. Capital gains, if
any, are paid in December. In participant accounts, all distributions are
automatically reinvested.

In evaluating past performance, remember that it is not indicative of future
performance and that returns from stocks before adjusting for inflation were
relatively high during the periods shown. Performance figures include the
reinvestment of any dividends and capital gains distributions. The returns shown
are net of expenses for the Fund, but they do not reflect income taxes an
investor would have incurred. The Composite Index is a theoretical portfolio,
incurring none of the advisory fees, operating expenses, and portfolio
transaction costs that are borne by an operating mutual fund. Note, too, that
both the return and principal value of an investment will fluctuate so that
investors' shares, when redeemed, may be worth more or less than their original
cost.

                             THE COSTS OF INVESTING

Costs are an important consideration in choosing a mutual fund. That's because
you, as a shareholder, pay the costs of operating a fund, plus any transaction
costs associated with buying, selling, or exchanging shares. These costs can
erode a substantial portion of the gross income or capital appreciation a fund
achieves. Even seemingly small differences in fund expenses can, over time, have
a dramatic impact on a fund's performance. 


                                PLAIN TALK ABOUT

                                  FUND EXPENSES

All mutual funds have operating expenses. These expenses, which are deducted
from a fund's gross income, are expressed as a percentage of the net assets of
the fund. Vanguard/Wellington Fund's expense ratio in fiscal year 1996 was
0.31%, or $3.10 per $1,000 of average net assets. The average balanced mutual
fund had expenses in 1996 of 1.32%, or $13.20 per $1,000 of average net assets,
according to Lipper Analytical Services, Inc., which reports on the mutual fund
industry.


FUND EXPENSES

The examples below are designed to help you understand the various costs you
would bear, directly or indirectly, as an investor in the Fund.

      As noted in this table, you do not pay fees of any kind when you buy,
sell, or exchange shares of the Fund:

SHAREHOLDER TRANSACTION EXPENSES

Sales Load Imposed on Purchases:                            None
Sales Load Imposed on Reinvested Dividends:                 None
Redemption Fees:                                            None
Exchange Fees:                                              None

      The next table illustrates the operating expenses that you would incur as
a shareholder of the Fund. These expenses are deducted from the Fund's income
before it is paid to you. Expenses include investment advisory fees as well as
the costs of maintaining accounts, administering the Fund, providing shareholder
services, and other activities. The expenses shown in the table are for the
fiscal year ended November 30, 1996.

      The following example illustrates the hypothetical expenses that you would
incur on a $1,000 investment over various periods. The example assumes (1) that
the Fund provides a return of 5% a year and (2) that you redeem your investment

</TABLE>

      From time to time, the Vanguard funds advertise yield and total return
figures. Yield is an historical measure of dividend income, and total return is
a measure of past dividend income (assuming that it has been reinvested) plus
capital appreciation. Neither yield nor total return should be used to predict
the future performance of a fund.


                                PLAIN TALK ABOUT

                   HOW TO READ THE FINANCIAL HIGHLIGHTS TABLE

The Fund began fiscal 1996 with a net asset value (price) of $24.57 per share.
During the year, the Fund earned $1.02 per share from investment income
(interest and dividends) and $4.00 per share from investments that had
appreciated in value or that were sold for higher prices than the Fund paid for
them. Of those total earnings of $5.02 per share, $0.97 per share was returned
to shareholders in the form of dividend distributions, and $0.28 per share in
the form of capital gains distributions. The earnings ($5.02 per share) less
total distributions ($1.25 per share) resulted in a share price of $28.34 at the
end of the year, an increase of $3.77 per share (from $24.57 at the beginning of
the period to $28.34 at the end of the period). Assuming that the shareholder
had reinvested the distributions in the purchase of more shares, total return
from the Fund was 21.26% for the year.

      As of November 30, 1996, the Fund had $16.5 billion in net assets; an
expense ratio of 0.31% ($3.10 per $1,000 of net assets); and net investment
income amounting to 4.08% of its average net assets. It sold and replaced
securities valued at 30% of its total net assets.

                                 BALANCED FUNDS

   Balanced funds are "middle-of-the-road" investments that seek to provide
some combination of growth, income, and conservation of capital by investing in
a mix of stocks, bonds, and/or money market instruments. Because stocks and
bonds tend to move in different directions, balanced funds are able to use the
rewards from one type of investment to help offset the risks from another.


A WORD ABOUT RISK

This prospectus describes the risks you will face as an investor in
Vanguard/Wellington Fund. It is important to keep in mind one of the main axioms
of investing: the higher the risk of losing money, the higher the potential
reward. The reverse, also, is generally true: the lower the risk, the lower the
potential reward. However, as you consider an investment in Vanguard/Wellington
Fund, you should also take into account your personal tolerance for the daily
fluctuations of both the stock and bond markets.

   Look for the "warning flag" symbol [FLAG GRAPHIC] throughout the prospectus.
It is used to mark detailed information about each type of risk that you, as a
shareholder of the Fund, will confront.

THE FUND'S OBJECTIVES

The Fund seeks to conserve capital and to provide moderate long-term capital
growth and moderate income. These objectives are not fundamental, which means
that they can be changed by the Fund's board of directors without shareholder
approval. However, before making any important change in its objectives, the
Fund will give shareholders 30-days notice, in writing.


[FLAG       BECAUSE OF THE SEVERAL TYPES OF RISK DESCRIBED ON THE FOLLOWING
GRAPHIC]    PAGES, YOUR INVESTMENT IN THE FUND, AS WITH ANY INVESTMENT IN STOCKS
            AND BONDS, COULD LOSE MONEY.

WHO SHOULD INVEST

The Fund may be a suitable investment for you if:

- -  You wish to add a balanced fund to your existing holdings, which could
   include other stock and bond -- as well as money market and tax-exempt --
   investments. 

- -  You are seeking moderate growth of your capital over the long term -- at
   least five years -- while, at the same time, conserving your capital as much
   as possible.

- -  You are seeking moderate income.

- -  You want a simple way to invest in a relatively fixed percentage of stocks
   and bonds.

   This Fund is not an appropriate investment if you are a market-timer.
Investors who engage in excessive in-and-out trading activity generate
additional costs that are borne by all of the Fund's shareholders. To minimize
such costs, which reduce the ultimate returns achieved by you and other
shareholders, the Fund has adopted the following policies:

                                       4
<PAGE>   38
- -  The Fund reserves the right to reject any purchase request -- including
   exchanges from other Vanguard funds -- that it regards as disruptive to the
   efficient management of the Fund. This could be because of the timing of the
   investment or because of a history of excessive trading by the investor.

- -  There is a limit on the number of times you can exchange into or out of the
   Fund. If you own shares of the Fund as an investment option in an
   employer-sponsored retirement or savings plan, your plan dictates the rules
   governing exchanges. Contact your plan administrator for details.

- -  The Fund reserves the right to stop offering shares at any time.

INVESTMENT STRATEGIES

This section explains how Vanguard/Wellington Fund's investment adviser pursues
the objectives of conservation of capital, moderate long-term capital growth,
and moderate current income. It also explains important risks -- stock market
risk, interest rate risk, manager risk, and credit risk -- faced by investors in
the Fund. Like the Fund's objectives, the adviser's investment strategies are
not fundamental and can be changed by the Fund's board of directors without
shareholder approval. However, before making any important change in its
strategies, the Fund will give shareholders 30-days notice, in writing.

MARKET EXPOSURE

STOCKS

Roughly two-thirds of the Fund's assets are invested in common stocks. At times,
the Fund may also invest in securities that are convertible into common stocks.

[FLAG       THE FUND IS SUBJECT TO STOCK MARKET RISK, WHICH IS THE POSSIBILITY
GRAPHIC]    THAT STOCK PRICES OVERALL WILL DECLINE OVER SHORT OR EVEN EXTENDED
            PERIODS. STOCK MARKETS TEND TO MOVE IN CYCLES, WITH PERIODS OF
            RISING STOCK PRICES AND PERIODS OF FALLING STOCK PRICES.

   To illustrate the volatility of stock prices, the following table shows the
best, worst, and average total returns (dividend income plus change in market
value) for the U.S. stock market over various periods as measured by the
Standard & Poor's 500 Composite Stock Price Index, a widely used barometer of
stock market activity. Note that the returns shown do not include the costs of
buying and selling stocks or other expenses that a real-world investment
portfolio would incur. Note, also, how the gap between best and worst tends to
narrow over the long term.

                                PLAIN TALK ABOUT

                             COSTS AND MARKET TIMING

Some investors try to profit from "market timing" -- switching money into
investments when they expect prices to rise, and taking money out when they
expect the market to fall. As money is shifted in and out, a fund incurs
expenses for buying and selling securities. These costs are borne by all fund
shareholders, including long-term investors who do not generate the costs.
Therefore, the Fund discourages short-term trading by, among other things,
closely monitoring daily transactions.

                            BONDS AND INTEREST RATES

As a rule, when interest rates rise, bond prices fall. The opposite is also
true: Bond prices go up when interest rates fall. Why do bond prices and
interest rates move in opposite directions? Let's assume that you hold a bond
offering a 5% yield. A year later, interest rates are on the rise and bonds are
offered with a 6% yield. With higher-yielding bonds available, you would have
trouble selling your 5% bond for the price you paid -- causing you to lower your
asking price. On the other hand, if interest rates were falling and 4% bonds
were being offered, you would be able to sell your 5% bond for more than you
paid.


                                PLAIN TALK ABOUT

                                 BOND MATURITIES

A bond is issued with a specific maturity date -- the date when the bond's
issuer, or seller, must pay back the bond's initial value (known as its "face
value"). Bond maturities generally range from less than one year (short term) to
30 years (long term). The longer a bond's maturity, the more risk you, as a bond
investor, face as interest rates rise -- but also the more interest you could
receive. Long-term bonds are more suitable for investors willing to take greater
risks in hope of higher yields; short-term bond investors should be willing to
accept lower yields in return for less fluctuation in the value of their
investment.

- ------------------------------------------------------------------

   The table covers all of the 1-, 5-, 10-, and 20-year periods from 1926
through 1996. For example, while the average return on stocks for all of the
5-year periods was 10.4%, returns for these 5-year periods ranged from a -12.5%
average (from 1928 through 1932), to 23.9% (from 1950 through 1954). These
average returns reflect past performance on common stocks and should not be
regarded as an indication of future returns from either the stock market as a
whole or this Fund in particular.

   Finally, because Vanguard/Wellington Fund does not hold the same securities
held in the S&P 500 Index or any other market index, the performance of the Fund
will not mirror the returns of any particular index.

BONDS

Approximately one-third of the Fund's assets are invested in bonds.

[FLAG       THE FUND IS SUBJECT TO INTEREST RATE RISK, WHICH IS THE POSSIBILITY
GRAPHIC]    THAT BOND PRICES OVERALL WILL DECLINE OVER SHORT, OR EVEN EXTENDED,
            PERIODS DUE TO RISING INTEREST RATES. INTEREST RATE RISK SHOULD BE
            MODEST FOR SHORTER-TERM BONDS AND HIGH FOR LONGER-TERM BONDS.

   Although bonds are often thought to be less risky than stocks, there have
been periods when bond values have fallen significantly due to rising interest
rates. For instance, prices of long-term bonds fell by almost 48% between
December 1976 and September 1981.

   To illustrate the relationship between bond prices and interest rates, the

   Finally, because stock and bond prices often move in different directions,
the Fund's bond holdings help to dampen -- but not eliminate -- some of the
stock market volatility experienced by the Fund. Likewise, changes in interest
rates may not have as dramatic an effect on Wellington Fund as they would on a
fund made up entirely of bonds.

SECURITY SELECTION

Wellington Management Company, LLP (WMC), adviser to the Fund, invests
approximately 60% to 70% of the Fund's assets in dividend-paying common stocks
and the remaining 30% to 40% of assets in high-quality bonds. While the mix of
stocks and bonds varies from time to time depending on the adviser's views of
economic and market conditions, the stock portion can be expected to represent
at least 60% of the Fund's holdings.

   The Fund is run by WMC according to traditional methods of active investment
management. Securities are bought and sold based on WMC's judgments about
companies and their financial prospects, and about bond issuers and the general
level of interest rates. To achieve the Fund's objectives of conservation of
capital, moderate long-term growth, and moderate income, the adviser follows
specific strategies for stock selection and bond selection.

[FLAG       THE FUND IS SUBJECT TO MANAGER RISK, WHICH IS THE POSSIBILITY THAT
GRAPHIC]    WMC MAY DO A POOR JOB OF SELECTING STOCKS AND BONDS.

STOCKS

WMC uses extensive research to find what it considers to be undervalued stocks
of established, large- and medium-size companies. WMC considers a stock to be
undervalued if company earnings, or potential earnings, are not fully reflected
in the stock's share price. In other words, the current prices of these large-
and mid-cap stocks may be less than what the adviser thinks they are truly
worth.

   The adviser's goal is to identify and purchase these securities before their
value is recognized by other investors. The adviser emphasizes stocks that, on
average, provide a higher level of dividend income than stocks in the overall
market generally provide. By adhering to this stock selection strategy and by
investing in a wide variety of companies and industries, the adviser expects to
moderate overall risk.

   The Fund's top ten stock holdings (which amounted to 16% of the Fund's net
assets) as of November 30, 1996, follow.

    1. General Electric Co.
    2. Allstate Corp.

                    LARGE-CAP, MID-CAP, AND SMALL-CAP STOCKS

Stocks of publicly traded companies -- and mutual funds that hold these stocks
- -- can be classified by the companies' market value, or capitalization. Vanguard
defines large-capitalization, or large-cap, funds as those holding stocks of
companies with a median market value of their outstanding shares exceeding $5
billion. Mid-cap funds hold stocks of companies with a median market value
between $1 billion and $5 billion. Small-cap funds hold stocks of companies with
a median market value of less than $1 billion. Historically, large-cap funds
have exhibited lower volatility than mid-cap and small-cap funds.

                                 TYPES OF BONDS

Bonds are issued (sold) by many sources: corporations issue corporate bonds; the
federal government issues U.S. Treasury bonds; agencies of the federal
government issue agency bonds; and mortgage holders issue "mortgage-backed"
bonds such as Government National Mortgage Association (GNMA). Each issuer is
responsible for paying back the bond's initial value as well as periodic
interest payments.

                                 CREDIT QUALITY

A bond's credit quality depends on the issuer's ability to pay interest on the
bond and, ultimately, to repay the debt. The lower the rating by one of the
independent bond-rating agencies (for example, Moody's or Standard & Poor's),
the greater the chance (in the rating agency's opinion) that the bond issuer
will default, or fail to meet its payment obligations. All things being equal,
the lower a bond's credit rating, the higher the yield the bond seeks to pay (as
compensation for the risks an investor must take).

                               PORTFOLIO TURNOVER

Before investing in a mutual fund, you should review its portfolio turnover rate
for an indication of the potential effect of transaction costs on the fund's
future returns. In general, the greater the volume of buying and selling by the
fund, the greater the impact that brokerage commissions and other transaction
costs will have on its return. The average turnover rate for actively managed
balanced funds is 86%.

   Keep in mind that, because the stock makeup of the Fund changes daily, this
listing is only a "snapshot" at one point in time.

BONDS

WMC selects high-quality bonds that, it believes, will generate a high and
sustainable level of income. These bonds would include intermediate- and
long-term corporate bonds, U.S. Treasury, government agency, and mortgage-backed
and asset-backed bonds.

   A breakdown of the Fund's bond holdings (which amounted to 34% of the Fund's
total net assets) as of November 30, 1996, follows.

GRAPHIC]    THE POSSIBILITY THAT A BOND ISSUER WILL FAIL TO REPAY INTEREST AND
            PRINCIPAL IN A TIMELY MANNER.

   WMC purchases bonds that are primarily investment-grade quality -- that is,
the bonds are rated at least Baa by Moody's Investors Service, Inc., or BBB by
Standard & Poor's Corporation. The average quality of bonds held by the Fund, as
of November 30, 1996, was Aa2, according to Moody's.

   The U.S. government guarantees the timely payment of interest and principal
for its Treasury bonds, but does not guarantee its bonds' prices. In other
words, while the Treasury bonds enjoy the highest credit ratings, their prices
- -- like the prices of other bonds in the Fund -- will fluctuate with changes in
interest rates.

PORTFOLIO TURNOVER

Although the Fund generally seeks to invest for the long term, it retains the
right to sell securities regardless of how long they have been held. It is not
expected that the Fund's turnover rate would exceed 50% in the future. (A
turnover rate of 100% would occur, for example, if the Fund sold and replaced
securities valued at 100% of its total net assets within a one-year period.)

INVESTMENT POLICIES

Besides investing in stocks of large and medium-size companies and high-quality
intermediate- and long-term bonds issued by corporations, the U.S. government,
and its agencies, the Fund may follow a number of investment policies to achieve
its objectives.

                                       8
<PAGE>   42
   Up to 15% of the Fund's assets may be invested in the common stocks of
foreign companies as well as securities that are convertible into foreign
stocks. The Fund may engage in currency transactions with respect to these
securities. The Fund may also invest in fixed-income securities issued by
foreign governments and non-U.S.-based companies; however, these securities must
be valued in U.S. dollars and meet the Fund's credit quality standards. Over the
years, the prices of foreign investments and the prices of U.S. investments have
often moved in different directions. In addition, international markets operate
differently from U.S. markets. For instance, foreign exchanges, brokers, and
companies generally have less government supervision and regulation than in the
U.S.

   The Fund may invest up to 15% of its assets in restricted securities with
limited marketability or other illiquid securities.

   The Fund may also invest in derivatives.

[FLAG       THE FUND RESERVES THE RIGHT TO INVEST, TO A LIMITED EXTENT, IN STOCK
GRAPHIC]    AND BOND (INTEREST RATE) FUTURES AND OPTIONS CONTRACTS, WHICH ARE
            TRADITIONAL TYPES OF DERIVATIVES. THE FUND MAY ALSO INVEST MODESTLY
            IN LESS RISKY CLASSES OF COLLATERALIZED MORTGAGE OBLIGATIONS (CMOS).

   Losses (or gains) involving futures can sometimes be substantial -- in part
because a relatively small price movement in a futures contract may result in an
immediate and substantial loss (or gain) for a Fund. This Fund will not use
futures and options for speculative purposes or as leveraged investments that
magnify the gains or losses of an investment. If it holds futures and options,
the Fund will keep separate cash reserves or short-term cash-equivalent
securities in the amount of the obligation underlying the futures contract. Only
a limited percentage of the Fund's assets -- up to 5% if required for deposit
and no more than 20% of total assets -- may be committed to such contracts.

   The reasons for which the Fund may use futures and options are:

- -  To keep cash on hand to meet shareholder redemptions or other needs while
   simulating full investment in stocks and bonds.

- -  To make it easier to trade.

- -  To reduce costs by buying futures instead of actual stocks or bonds when
   futures are cheaper.

   Please see the Statement of Additional Information for a more detailed
discussion of the Fund's investments in derivatives. The Fund will usually hold
only a small percentage of its assets in cash reserves, although if the
investment adviser believes that market conditions warrant a temporary defensive
measure, the Fund may hold cash reserves without limit.

INVESTMENT LIMITATIONS

To reduce risk and maintain diversification, the Fund has adopted limits on some
of its investment policies. Specifically, the Fund will not:

A derivative is a financial contract whose value is based on (or "derived" from)
a traditional security (such as a stock or a bond), an asset (such as a
commodity like gold), or a market index (such as the S&P 500 Index). Futures and
options are derivatives that have been trading on regulated exchanges for more
than two decades. These "traditional" derivatives are standardized contracts
that can easily be bought and sold, and whose market values are determined and
published daily. It is these characteristics that differentiate futures and
options from the relatively new, exotic types of derivatives -- some of which
can carry considerable risks.

INVESTMENT PERFORMANCE

As a balanced fund, Vanguard/Wellington Fund invests primarily in stocks, with a
sizable holding of bonds -- so Fund performance is closely tied to both the
stock and bond markets. Historically, stock market performance has been
characterized by sharp up-and-down swings in the short term, and by more stable
growth over the long term. Bond market performance has been -- and remains --
strongly influenced by changes in interest rates.

SHARE PRICE

The Fund's share price, called its net asset value, is calculated each business
day after the close of trading (generally 4 p.m. Eastern time) of the New York
Stock Exchange. Net asset value per share is calculated by adding up the total
assets of the Fund, subtracting all of its liabilities, or debts, and then
dividing by the total number of Fund shares outstanding:

                            Total Assets  -  Liabilities

   Net Asset Value  =       ----------------------------

                            Number of Shares Outstanding

   The daily net asset value, or NAV, is useful to you as a shareholder because
the NAV, multiplied by the number of Fund shares you own, gives you the dollar
amount you would have received had you sold all of your shares back to the Fund
that day.

   The Fund's share price can be found daily in the mutual fund listings of most
major newspapers under the heading Vanguard Group. Different newspapers use
different abbreviations of the Fund's name, but the most common is WELLTN.

DIVIDENDS, CAPITAL GAINS, AND TAXES

Each March, June, September, and December, the Fund distributes to shareholders
virtually all of its income from interest and dividends. Any capital gains
realized from the sale of securities are distributed in December.

   If you own shares of the Fund as an investment option in an
employer-sponsored retirement or savings plan, these dividend and capital gains
distributions will be reinvested in additional Fund shares and accumulate on a
tax-deferred basis. You will not owe taxes on these distributions until you
begin withdrawals. You should consult your plan administrator, your plan's
Summary Plan Document, or your own tax adviser about the tax consequences of an
investment in the Portfolio and of any plan withdrawals.

   If your Vanguard/Wellington Fund investment is not part of an
employer-sponsored plan, you can receive distributions of income or capital
gains in cash, or you may have them automatically reinvested in more shares of
the Fund. Both dividend and capital gains distributions -- whether received in
cash or reinvested in additional shares -- are subject to federal (and possibly
state and local) income taxes, no matter how long you have held the shares in
the Fund. You should consult your own tax adviser about other tax consequences
of an investment in the Fund.

                                  DISTRIBUTIONS

As a shareholder, you are entitled to your share of the fund's income from
interest and dividends, and gains from the sale of investments. You receive such
earnings as either an income dividend or capital gains distribution. Income
dividends come from interest the fund earns from its money market and bond
investments as well as dividends it receives from its stock investments. Capital
gains are realized whenever the fund sells securities for higher prices than it
paid for them. These capital gains are either short-term or long-term depending
on whether the fund held the securities for less than or more than one year.

The Vanguard Group, Inc. is the only MUTUAL mutual fund company. It is owned
jointly by the funds it oversees and by the shareholders in those funds. Other
mutual funds are operated by for-profit management companies that may be owned
by one person, by a group of individuals, or by investors who bought the
management company's publicly traded stock. Because of its structure, Vanguard
operates its funds at cost. Instead of distributing profits from operations to a
separate management company, Vanguard returns profits to fund shareholders in

                               THE FUND'S ADVISER

Wellington Management Company, LLP (WMC), an investment advisory firm founded in
1933, currently manages more than $133 billion in stock and bond portfolios,
including 13 Vanguard funds. The managers responsible for overseeing
Vanguard/Wellington Fund are:

   ERNST H. VON METZSCH, CFA, Senior Vice President of WMC; 27 years investment
experience, 24 years with WMC; M.Sc. from The University of Leiden, The
Netherlands, Ph.D. from Harvard University.

   PAUL D. KAPLAN, Senior Vice President of WMC; 23 years investment experience,
19 years with WMC; B.S. from Dickinson College, M.S. from The Sloan School of
Management, Massachusetts Institute of Technology.


THE FUND AND VANGUARD

The Fund is a member of The Vanguard Group, a family of more than 30 investment
companies with more than 90 distinct investment portfolios and total net assets
of more than $250 billion. All of the Vanguard Funds share in the expenses
associated with business operations, such as personnel, office space, equipment,
and advertising.

   Vanguard also provides marketing services to the funds. Although shareholders
do not pay sales commissions or 12b-1 marketing fees, each fund pays its
allocated share of The Vanguard Group's costs.

   A list of the Fund's directors and officers, and their present positions and
principal occupations during the past five years, can be found in the Statement
of Additional Information.

INVESTMENT ADVISER

The Fund employs Wellington Management Company, LLP (WMC), 75 State Street,
Boston, MA 02109, as its investment adviser. WMC manages the Fund subject to the
control of the officers and directors of the Fund.

   Each quarter, WMC is paid an advisory fee based on average month-end net
assets of the Fund and a sliding percentage scale:

                --------------------------------
                ASSETS MANAGED              FEE
                --------------------------------
                First $1 billion           0.10%
                Next $2 billion            0.05
                Next $7 billion            0.04
                Assets over $10 billion    0.03
                --------------------------------

   The advisory fee can be increased or decreased based on the difference
between the Fund's total return performance and that of an unmanaged "composite
index," which is made up of the S&P 500 Index (65% of the composite index) and
Lehman Brothers Long-Term Corporate AA or Better Bond Index (35% of the
composite index). Under the fee schedule, the base fee may be increased or
decreased by up to 30%. The incentive/penalty fee will not be in full operation
until the quarter ending May 31, 1999. Until that date, the incentive/penalty
fee will be calculated using certain transition rules that are explained in the
Statement of Additional Information.

   For the year ended November 30, 1996, the investment advisory fee paid to WMC
was $6.12 million.

   The agreement authorizes WMC to choose brokers or dealers to handle the
purchase and sale of the Fund's securities, and directs WMC to get the best
available price and most favorable execution from these brokers with respect to
all transactions. At times, WMC may choose brokers who charge higher commissions
in the interest of obtaining better execution of a transaction. If more than one
broker can obtain the best available price and favorable execution of a

                                       12
<PAGE>   46
transaction, then WMC is authorized to choose a broker who, in addition to
executing the transaction, will provide research services to WMC or the Fund.
However, WMC will not pay higher commissions specifically for the purpose of
obtaining research services. The Fund may direct WMC to use a particular broker
for certain transactions in exchange for commission rebates or research services
provided to the Fund.

   The board of directors may, without prior approval from shareholders, change
the terms of the advisory agreement or hire a new investment adviser, either as
a replacement for WMC or as an additional adviser. However, no such change would
be made before giving shareholders 30-days notice, in writing.

GENERAL INFORMATION

Vanguard/Wellington Fund is a corporation organized under the laws of the state
of Maryland. Shareholders of the Fund have rights and privileges similar to
those enjoyed by other corporate shareholders. For example, shareholders will
not be responsible for any liabilities of the corporation. If any matters are to
be voted on by shareholders (such as the election of directors), each share
outstanding at that point would be entitled to one vote. Annual meetings will
not be held by the Fund except as required by the Investment Company Act of
1940. A meeting will be scheduled if the holders of at least 10% of the Fund's
shares request a meeting in writing.

GLOSSARY OF INVESTMENT TERMS



BALANCED FUND

A mutual fund that seeks to provide some combination of income, capital growth,
and conservation of capital by investing in stocks, bonds, and/or money market
instruments.

BOND

A debt security (IOU) issued by a corporation, government, or government agency
in exchange for the money you lend it. In most instances, the issuer agrees to
pay back the loan by a specific date and make regular interest payments until
that date.

CAPITAL GAINS DISTRIBUTION

Payment to mutual fund shareholders of gains realized during the year on
securities that the fund has sold at a profit, minus any realized losses.

CASH RESERVES

Cash deposits as well as short-term bank deposits, money market instruments,
U.S. Treasury bills, commercial paper, and banker's acceptances.

COMMON STOCK

A security representing ownership rights in a corporation. A stockholder is
entitled to share in the company's profits, some of which may be paid out as
dividends.

CREDIT QUALITY

A measure of a bond issuer's ability to repay interest and principal in a timely
manner.

DIVIDEND INCOME

Payment to shareholders of income from interest or dividends generated by a
fund's investments.

EXPENSE RATIO

The percentage of a fund's average net assets used to pay its expenses. The
expense ratio includes management fees, administrative fees, and any 12b-1
marketing fees.

FACE VALUE

The value of a bond at the time it was issued (that is, initially sold).

FIXED-INCOME SECURITIES

Investments, such as bonds, that have a fixed payment schedule. While the level
of income offered by these securities is predetermined, their prices may
fluctuate.

INVESTMENT GRADE

Bonds whose credit quality is considered to be among the highest by independent
bond-rating agencies.

MATURITY

The date when a bond issuer agrees to repay the bond's principal, or face value,
to the bond's buyer.

MUTUAL FUND

An investment company that pools the money of many people and invests it in a
variety of securities in an effort to achieve a specific objective over time.

NET ASSET VALUE (NAV)

The market value of a mutual fund's total assets, minus liabilities, divided by
the number of shares outstanding. The value of a single share is called its
share value or share price.

PORTFOLIO DIVERSIFICATION

Holding a variety of securities so that a portfolio's return is not hurt by the
poor performance of a single security or industry.

PRICE/EARNINGS (P/E) RATIO

The current share price of a stock, divided by its per-share earnings (profits)
from the past year. A stock selling for $20, with earnings of $2 per share, has
a price/earnings ratio of 10.

TOTAL RETURN

A percentage change, over a specified time period, in a mutual fund's net asset
value, with the ending net asset value adjusted to account for the reinvestment
of all distributions of dividends and capital gains.

VOLATILITY

The fluctuations in value of a mutual fund or other security. The greater a
fund's volatility, the wider the fluctuations between its high and low prices.

YIELD

Current income (interest or dividends) earned by an investment, expressed as a
percentage of the investment's price.

                       INVESTMENT OBJECTIVES AND POLICIES
 
     The following policies supplement the Fund's investment objectives and
policies set forth in the Prospectus.
 
   
     REPURCHASE AGREEMENTS  The Fund may invest in repurchase agreements with
commercial banks, brokers, or dealers either for defensive purposes due to
market conditions or to generate income from its excess cash balances. A
repurchase agreement is an agreement under which the Fund acquires a money
market instrument (generally a security issued by the U.S. Government or an
agency thereof, a banker's acceptance or a certificate of deposit) from a
commercial bank, broker or dealer, subject to resale to the seller at an agreed
upon price and date (normally, the next business day). A repurchase agreement
may be considered a loan collateralized by securities. The resale price reflects
an agreed upon interest rate effective for the period the instrument is held by
the Fund and is unrelated to the interest rate on the underlying instrument. In
these transactions, the securities acquired by the Fund (including accrued
interest earned thereon) must have a total value in excess of the value of the
repurchase agreement and are held by a Custodian Bank until repurchased. In
addition, the Fund's Board of Directors will monitor the Fund's repurchase
agreement transactions generally and will establish guidelines and standards for
review by the investment adviser of the creditworthiness of any bank, broker or
dealer party to a repurchase agreement with the Fund. No more than an aggregate
of 15% of the Fund's assets, at the time of investment, will be invested in
repurchase agreements having maturities longer than seven days and securities
subject to legal or contractual restrictions on resale for which there are no
readily available market quotations. See "Illiquid Securities" on page 2.
    
 
     The use of repurchase agreements involves certain risks. For example, if
the other party to the agreement defaults on its obligation to repurchase the
underlying security at a time when the value of the security has declined, the
Fund may incur a loss upon disposition of the security. If the other party to
the agreement becomes insolvent and subject to liquidations or reorganization
under the Bankruptcy Code or other laws, a court may determine that the
underlying security is collateral for a loan by the Fund not within the control
of the Fund and therefore the realization by the Fund on such collateral may be
automatically stayed. Finally, it is possible that the Fund may not be able to
substantiate its interest in the underlying security and may be deemed an
unsecured creditor of the other party to the agreement. While the Fund's
management acknowledges these risks, it is expected that they can be controlled
through careful monitoring procedures.

     LENDING OF SECURITIES  The Fund may lend its portfolio securities to
qualified institutional investors who need to borrow securities in order to
complete certain transactions, such as covering short sales, avoiding failures
to deliver securities or completing arbitrage operations. By lending its
portfolio securities, the Fund attempts to increase its income through the
receipt of interest on the loan. Any gain or loss in the market price of the
securities loaned that might occur during the term of the loan would be for the
account of the Fund. The Fund may lend its portfolio securities to qualified
brokers, dealers, banks or other financial institutions, so long as the terms,
the structure and the aggregate amount of such loans are consistent with the
Investment Company Act of 1940, or the Rules and Regulations or interpretations
of the Securities and Exchange Commission (the "Commission") thereunder, which
currently require that (a) the borrower pledge and maintain with the Fund
collateral consisting of cash, a letter of credit issued by a domestic U.S.
bank, or securities issued or guaranteed by the United States Government having
a value at all times not less than 100% of the value of the securities loaned,
(b) the borrower add to such collateral whenever the price of the securities
loaned rises (i.e., the borrower "marks to the market" on a daily basis), (c)
the loan be made subject to termination by the Fund at any time, and (d) the
Fund receive reasonable interest on the loan (which may include the Fund's
investing any cash collateral in interest bearing short-term investments), any
distribution on the loaned securities and any increase in their market value.
Loan arrangements made by the Fund will comply with all other applicable
regulatory requirements, including the rules of the New York Stock Exchange,
whose rules presently require the borrower, after notice, to redeliver the
securities within the normal settlement time of three business days. All
relevant facts and circumstances, including the creditworthiness of the broker,
dealer or institution, will be considered in making decisions with respect to
the lending of securities, subject to review by the Fund's Board of Directors.
    
 
     At the present time, the Staff of the Commission does not object if an
investment company pays reasonable negotiated fees in connection with loaned
securities, so long as such fees are set forth in a written contract and
approved by the investment company's directors. In addition, voting rights pass
with the loaned securities but if a material event will occur affecting an
investment on loan, the loan must be called and the securities voted.
 
   
     ILLIQUID SECURITIES  Illiquid securities are securities that may not be
sold or disposed of in the ordinary course of business within seven business
days at approximately the value at which they are being carried on a Fund's
books. An illiquid security includes repurchase agreements which have a maturity
of longer than seven days, securities which are illiquid by virtue of the
absence of a readily available market, and demand instruments with a demand
notice exceeding seven days. Illiquid securities may include securities that are
not registered under the Securities Act of 1933 (the "1933 Act"); however,
unregistered securities that can be sold to "qualified institutional buyers" in
accordance with Rule 144A under the 1933 Act will not be considered illiquid so
long as it is determined by the Fund's advisor that an adequate trading market
exists for the security. From time to time, the Fund's Board of Directors or the
Fund's Adviser may determine that certain restricted securities known as Rule
144A securities are liquid and not subject to the 15% limitation described
above.
    
 
   
     MORTGAGE-BACKED SECURITIES  The Fund may invest in mortgage-backed
securities. Mortgage-backed securities are instruments that entitle the holder
to a share of all interest and principal payments from mortgages underlying the
security. The mortgages backing these securities include conventional
thirty-year fixed rate mortgages, graduated payment mortgages and adjustable
rate mortgages. During periods of declining interest rates, prepayment of
mortgages underlying mortgage-backed securities may be expected to accelerate.
Prepayment of mortgages which underlie securities purchased at a premium often
results in capital losses, while prepayment of mortgages purchased at a discount
often results in capital gains. Because of these unpredictable prepayment
characteristics, it is often not possible to predict accurately the average life
or realized yield of a particular issue.
    
 
   
     COLLATERALIZED MORTGAGE OBLIGATIONS ("CMOS")  CMOs are debt obligations or
multi-class pass-through certificates issues by agencies or instrumentalities of
the U.S. Government, or by private originators or investors in mortgage loans.
In a CMO, series of bonds or certificates are usually issued in multiple
classes, with principal and interest allocated to each class in a variety of
ways. Each class of a CMO or "tranche" is issued with a specific fixed or
floating coupon rate and has a stated maturity or final distribution date. The
Fund will invest modestly in those CMO classes which feature a high degree of
cash flow predictability and moderate vulnerability to prepayment risk, and that
carry high-quality investment grade credit ratings.
    
 
                                        2
<PAGE>   54
 
   
     FOREIGN INVESTMENTS  As indicated in the Prospectus, the Fund may invest up
to 15% of its equity assets in foreign common stocks and securities convertible
into common stocks. The Fund may also invest in U.S. dollar denominated debt
securities issued by foreign governments, their agencies and instrumentalities,
supranational entities and companies located outside the U.S. without limit.
Investors should recognize that investing in foreign companies involves certain
special considerations which are not typically associated with investing in U.S.
companies.
    
 
     Country Risk  As foreign companies are not generally subject to uniform
accounting, auditing and financial reporting standards and practices comparable
to those applicable to domestic companies, there may be less publicly available
information about certain foreign companies than about domestic companies.
Securities of some foreign companies are generally less liquid and more volatile
than securities of comparable domestic companies. There is generally less
government supervision and regulation of stock exchanges, brokers and listed
companies than in the U.S. In addition, with respect to certain foreign
countries, there is the possibility of expropriation or confiscatory taxation,
political or social instability, or diplomatic developments which could affect
U.S. investments in those countries.
 
   
     Although the Fund will endeavor to achieve most favorable execution costs
in its portfolio transactions in foreign securities, fixed commissions on many
foreign stock exchanges are generally higher than negotiated commissions on U.S.
exchanges. In addition, it is expected that the expenses for custodial
arrangements of the Fund's foreign securities will be somewhat greater than the
expenses for the custodial arrangement for handling U.S. securities of equal
value.
    
 
     Certain foreign governments levy withholding taxes against dividend and
interest income. Although in some countries a portion of these taxes is
recoverable, the non-recovered portion of foreign withholding taxes will reduce
the income the Fund receives from its foreign investments.
 
     Currency Risk  Since the stocks of foreign companies are frequently
denominated in foreign currencies, and since the Fund may temporarily hold
uninvested reserves in bank deposits in foreign currencies, the Fund will be
affected favorably or unfavorably by changes in currency rates and in exchange
control regulations, and may incur costs in connection with conversions between
various currencies. The investment policies of the Fund permit it to enter into
forward foreign currency exchange contracts in order to hedge holdings and
commitments against changes in the level of future currency rates. Such
contracts involve an obligation to purchase or sell a specific currency at a
future date at a price set at the time of the contract.
 
   
     FUTURES CONTRACTS  The Fund may enter into futures contracts, options, and
options on futures contracts for the purpose of simulating full investment and
reducing transactions costs. Futures contracts provide for the future sale by
one party and purchase by another party of a specified amount of a specific
security at a specified future time and at a specified price. Futures contracts
which are standardized as to maturity date and underlying financial instrument
are traded on national futures exchanges. Futures exchanges and trading are
regulated under the Commodity Exchange Act by the Commodity Futures Trading
Commission ("CFTC"), a U.S. Government agency. Assets committed to futures
contracts will be segregated at the Fund's custodian bank to the extent required
by law.
    
 
     Although futures contracts by their terms call for actual delivery or
acceptance of the underlying securities, in most cases the contracts are closed
out before the settlement date without the making or taking of delivery. Closing
out an open futures position is done by taking an opposite position ("buying" a
contract which has previously been "sold," or "selling" a contract previously
purchased) in an identical contract to terminate the position. Brokerage
commissions are incurred when a futures contract is bought or sold.
 
   
     Futures traders are required to make a good faith margin deposit in cash or
government securities with a broker or custodian to initiate and maintain open
positions in futures contracts. A margin deposit is intended to assure
completion of the contract (delivery or acceptance of the underlying security)
if it is not terminated prior to the specified delivery date. Minimal initial
margin requirements are established by the futures exchange and may be changed.
Brokers may establish deposit requirements which are higher than the exchange
minimums. Futures contracts are customarily purchased and sold, and margin
requirements may range upward from less than 5% of the value of the contract
being traded.
    
 
                                        3
<PAGE>   55
 
     After a futures contract position is opened, the value of the contract is
marked to market daily. If the futures contract price changes to the extent that
the margin on deposit does not satisfy margin requirements, payment of
additional "variation" margin will be required. Conversely, change in the
contract value may reduce the required margin, resulting in a repayment of
excess margin to the contract holder. Variation margin payments are made to and
from the futures broker as long as the contract remains open. The Fund expects
to earn interest income on its margin deposits.
 
     Traders in futures contracts may be broadly classified as either "hedgers"
or "speculators." Hedgers use the futures market primarily to offset unfavorable
changes in the value of securities otherwise held for investment purposes or
expected to be acquired by them. Speculators are less inclined to own the
securities underlying the futures contracts which they trade, and use futures
contracts with the expectation of realizing profits from fluctuations in the
prices of underlying securities. The Fund intends to use futures contracts only
for bona fide hedging purposes.
 
     Regulations of CFTC applicable to the Fund require that all of its futures
transactions constitute bona fide hedging transactions. The Fund will only sell
futures contracts to protect securities it owns against price declines or
purchase contracts to protect against an increase in the price of securities it
intends to purchase. As evidence of this hedging interest, the Fund expects that
approximately 75% of its futures contract purchases will be "completed," that
is, equivalent amounts of related securities will have been purchased or are
being purchased by the Fund upon sale of open futures contracts.
 
   
     Although techniques other than the sale and purchase of futures contracts
could be used to control the Fund's exposure to market fluctuations, the use of
futures contracts may be a more effective means of hedging this exposure. While
the Fund will incur commission expenses in both opening and closing out futures
positions, these costs are lower than transaction costs incurred in the purchase
and sale of underlying securities.
    
 
     RESTRICTIONS ON THE USE OF FUTURES CONTRACTS  The Fund will not enter into
futures contract transactions to the extent that, immediately thereafter, the
sum of its initial margin deposits on open contracts exceeds 5% of the market
value of the Fund's total assets. In addition, the Fund will not enter into
futures contracts to the extent that its outstanding obligations to purchase
securities under these contracts would exceed 20% of the Fund's total assets.
 
   
     RISK FACTORS IN FUTURES TRANSACTIONS  Positions in futures contracts may be
closed out only on an exchange which provides a secondary market for such
futures. However, there can be no assurance that a liquid secondary market will
exist for any particular futures contract at any specific time. Thus, it may not
be possible to close a futures position. In the event of adverse price
movements, the Fund would continue to be required to make daily cash payments to
maintain its required margin. In such situations, if the Fund has insufficient
cash, it may have to sell portfolio securities to meet daily margin requirements
at a time when it may be disadvantageous to do so. In addition, the Fund may be
required to make delivery of the instruments underlying futures contracts it
holds. The inability to close options and futures positions also could have an
adverse impact on the ability to hedge effectively.
    
 
     The Fund will minimize the risk that it will be unable to close out a
futures contract by only entering into futures which are traded on national
futures exchanges and for which there appears to be a liquid secondary market.
 
     The risk of loss in trading futures contracts in some strategies can be
substantial, due both to the low margin deposits required, and the extremely
high degree of leverage involved in futures pricing. As a result, a relatively
small price movement in a futures contract may result in immediate and
substantial loss (as well as gain) to the investor. For example, if at the time
of purchase, 10% of the value of the futures contract is deposited as margin, a
subsequent 10% decrease in the value of the futures contract would result in a
total loss of the margin deposit, before any deduction for the transaction
costs, if the account were then closed out. A 15% decrease would result in a
loss equal to 150% of the original margin deposit if the contract were closed
out. Thus, a purchase or sale of a futures contract may result in losses in
excess of the amount invested in the contract. However, because the futures
strategies of the Fund are engaged in only for hedging purposes, the Adviser
does not believe that the Fund is subject to the risks of loss frequently
associated with futures transactions. The Fund would presumably
 
                                        4
<PAGE>   56
 
have sustained comparable losses if, instead of the futures contract, it had
invested in the underlying financial instrument and sold it after the decline.
 
   
     Utilization of futures transactions by the Fund does involve the risk of
imperfect or no correlation where the securities underlying futures contracts
have different maturities than the portfolio securities being hedged. It is also
possible that the Fund could both lose money on futures contacts and also
experience a decline in value of its portfolio securities. There is also the
risk of loss by the Fund of margin deposits in the event of bankruptcy of a
broker with whom the Fund has an open position in a futures contract or related
option.
    
 
     Most futures exchanges limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price at the end of a trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price beyond that limit. The daily limit governs only
price movement during a particular trading day and therefore does not limit
potential losses, because the limit may prevent the liquidation of unfavorable
positions. Futures contract prices have occasionally moved to the daily limit
for several consecutive trading days with little or no trading, thereby
preventing prompt liquidation of future positions and subjecting some futures
traders to substantial losses.
 
     FEDERAL TAX TREATMENT OF FUTURES CONTRACTS  The Fund is required for
federal income tax purposes to recognize as income for each taxable year its net
unrealized gains and losses on certain futures contracts as of the end of the
year as well as those actually realized during the year. In most cases, any gain
or loss recognized with respect to a futures contract is considered to be 60%
long-term capital gain or loss and 40% short-term capital gain or loss, without
regard to the holding period of the contract. Furthermore, sales of futures
contracts which are intended to hedge against a change in the value of
securities held by the Fund may affect the holding period of such securities
and, consequently, the nature of the gain or loss on such securities upon
disposition. The Fund may be required to defer the recognition of losses on
futures contracts to the extent of any unrecognized gains on related positions
held by the Fund.
 
     In order for the Fund to continue to qualify for federal income tax
treatment as a regulated investment company, at least 90% of its gross income
for a taxable year must be derived from qualifying income; i.e., dividends,
interest, income derived from loans of securities, gains from the sale of
securities or of foreign currencies or other income derived with respect to the
Fund's business of investing in securities. In addition, gains realized on the
sale or other disposition of securities held for less than three months must be
limited to less than 30% of the Fund's annual gross income. It is anticipated
that any net gain realized from the closing out of futures contracts will be
considered gain from the sale of securities and therefore be qualifying income
for purposes of the 90% requirement. In order to avoid realizing excessive gains
on securities held less than three months, the Fund may be required to defer the
closing out of futures contracts beyond the time when it would otherwise be
advantageous to do so. It is anticipated that unrealized gains on futures
contracts, which have been open for less than three months as of the end of the
Fund's fiscal year and which are recognized for tax purposes, will not be
considered gains on sales of securities held less than three months for the
purpose of the 30% test.
 
   
     The Fund will distribute to shareholders annually any net capital gains
which have been recognized for Federal income tax purposes (including unrealized
gains at the end of the Fund's fiscal year) on futures transactions. Such
distributions will be combined with distributions of capital gains realized on
the Fund's other investments and shareholders will be advised on the nature of
the transactions.
    
 
                             YIELD AND TOTAL RETURN
 
   
     The yield of the Fund for the 30-day period ended November 30, 1996 was
+3.85%. Yields are calculated daily and premiums and discounts on asset-backed
accounts are not amortized.
    
 
   
     The average annual total return of the Fund for the one-, five- and
ten-year periods ending November 30, 1996 was +21.26%, +15.83% and +12.67%,
respectively. Total return is computed by finding the average compounded rates
of return over the one-, five- and ten-year periods set forth above that would
equate an initial amount invested at the beginning of the periods to the ending
redeemable value of the investment.

                               PURCHASE OF SHARES
 
   
     The purchase price of shares of the Fund is the net asset value next
determined after the order is received. The net asset value is calculated as of
the close of the New York Stock Exchange on each day the Exchange is open for
business. An order received prior to the close of the Exchange will be executed
at the price computed on the date of receipt; and an order received after the
close of the Exchange will be executed at the price computed on the next day the
Exchange is open.
    
 
     The Fund reserves the right in its sole discretion (i) to suspend the
offering of its shares, (ii) to reject purchase orders when in the judgment of
management such rejection is in the best interest of the Fund, and (iii) to
reduce or waive the minimum investment for or any other restrictions on initial
and subsequent investments for certain fiduciary accounts such as employee
benefit plans or under circumstances where certain economies can be achieved in
sales of the Fund's shares.
 
                              REDEMPTION OF SHARES
 
     The Fund may suspend redemption privileges or postpone the date of payment
(i) during any period that the New York Stock Exchange is closed, or trading on
the Exchange is restricted as determined by the Securities and Exchange
Commission (the "Commission"), (ii) during any period when an emergency exists
as defined by the rules of the Commission as a result of which it is not
reasonably practicable for the Fund to dispose of securities owned by it, or
fairly to determine the value of its assets, and (iii) for such other periods as
the Commission may permit.
 
     The Fund has made an election with the Commission to pay in cash all
redemptions requested by any shareholder of record limited in amount during any
90-day period to the lesser of $250,000 or 1% of the net assets of the Fund at
the beginning of such period. Such commitment is irrevocable without the prior
approval of the Commission. Redemptions in excess of the above limits may be
paid in whole or in part, in investment securities or in cash, as the Directors
may deem advisable; however, payment will be made wholly in cash unless the
Directors believe that economic or market conditions exist which would make such
a practice detrimental to the best interest of the Fund. If redemptions are paid
in investment securities, such securities will be valued as set forth in the
Prospectus under "The Fund's Share Price" and a redeeming shareholder would
normally incur brokerage expenses if he converted these securities to cash.
 
     No charge is made by the Fund for redemptions. Any redemption may be more
or less than the shareholder's cost depending on the market value of the Fund's
portfolio securities.
 
   
     SIGNATURE GUARANTEES  To protect your account, the Fund and Vanguard from
fraud, signature guarantees are required for certain redemptions. Signatures
guarantees enable the Fund to verify the identity of the person who has
authorized a redemption from your account. SIGNATURE GUARANTEES ARE REQUIRED IN
CONNECTION WITH: (1) ALL REDEMPTIONS, REGARDLESS OF THE AMOUNT INVOLVED, WHEN
THE PROCEEDS ARE TO BE PAID TO SOMEONE OTHER THAN THE REGISTERED OWNER(S) AND/OR
TO AN ADDRESS OTHER THAN THE ADDRESS OF RECORD; AND (2) SHARE TRANSFER REQUESTS.
These requirements are not applicable to redemptions in Vanguard's prototype
plans except in connection with: (1) distributions made when the proceeds are to
be paid to someone other than the plan participant; (2) certain authorizations
to effect exchanges by telephone; and (3) when proceeds are to be wired. These
requirements may be waived by the Fund in certain instances.
    
 
     Signature guarantees may be provided by banks, brokers, or any other
guarantor institution that Vanguard deems acceptable. NOTARIES PUBLIC ARE NOT
ACCEPTABLE GUARANTORS.
 
     The signature guarantees must appear either: (1) on the written request for
redemption; (2) on a separate instrument for assignment ("stock power") which
should specify the total number of shares to be redeemed; or (3) on all stock
certificates tendered for redemption and, if shares held by the Fund are also
being redeemed, on the letter or stock power.

                             INVESTMENT LIMITATIONS
 
   
     The Fund is subject to the following restrictions which may not be changed
without the approval of at least a majority of the outstanding voting securities
of the Fund. The Fund will not: (1) invest in commodities or real estate
although it may purchase and sell securities of companies which deal in real
estate or interests therein, and it may invest in stock and bond futures
contracts and options to the extent that not more than 5% of its assets are
required as deposit to secure obligations under futures contracts and not more
than 20% of the Fund's assets are invested in futures and options at any time;
(2) make loans except (i) by purchasing a portion of an issue of bonds,
debentures or similar obligations (including repurchase agreements) which are
publicly distributed or customarily purchased by institutional investors, and
(ii) as provided under "Lending of Securities" (See page 2); (3) with respect to
75% of the Fund's total assets, purchase the securities of any issuer (except
obligations of the United States Government and its instrumentalities) if as a
result the Fund would hold more than 10% of the outstanding voting securities of
the issuer, or more than 5% of the value of the Fund's total assets would be
invested in the securities of such issuer; (4) borrow money except up to a limit
of 10% of total assets for extraordinary or emergency purposes (the Fund has
never borrowed money and intends to limit any future borrowing to 5% of the
lower of the market value or cost of its assets); (5) engage in the business of
underwriting securities issued by other persons except to the extent that the
Fund may technically be deemed to be an underwriter under the Securities Act of
1933, as amended, in disposing of portfolio securities. Additionally, the Fund
will not purchase or otherwise acquire any security if, as a result, more than
15% of its net assets would be invested in securities that are illiquid (this
limitation includes the Fund's investment in The Vanguard Group, Inc.); (6)
purchase securities on margin (except as provided for above in (1)), or sell
securities short; (7) invest in securities of other investment companies, except
as may be acquired as a part of a merger, consolidation or acquisition of assets
or otherwise to the extent permitted by Section 12 of the Investment Company Act
of 1940. The Fund will invest only in investment companies which have investment
objectives and investment policies consistent with those of the Fund; (8) invest
to control other companies nor concentrate its investments in a particular
industry or group of industries.
    
 
     The above-mentioned investment limitations are considered at the time
investment securities are purchased. Notwithstanding these limitations, the Fund
may own the securities of, or make loans to, or contribute to the costs or other
financial requirements of any company which will be wholly-owned by the Fund and
one or more other investment companies and is primarily engaged in the business
of providing, at cost, management, administrative or related services to the
Fund and other investment companies (See "The Vanguard Group", page 8). As a
non-fundamental policy, the Fund will not purchase or retain securities of an
issuer if (i) one or more officers or directors of the Fund or its investment
adviser individually own or would own, directly or beneficially, more than 1/2
of 1% of the securities of such issuer and (ii) such persons own or would own in
the aggregate 5% of such securities.

THE VANGUARD GROUP
 
     The Fund is a member of The Vanguard Group of Investment Companies. Through
their jointly-owned subsidiary, The Vanguard Group, Inc. ("Vanguard"), the Fund
and the other Funds in the Group obtain at cost virtually all of their corporate
management, administrative and distribution services. Vanguard also provides
investment advisory services on an at-cost basis to several of the Vanguard
Funds.
 
     Vanguard employs a supporting staff of management and administrative
personnel needed to provide the requisite services to the Funds and also
furnishes the Funds with necessary office space, furnishings and equipment. Each
Fund pays its share of Vanguard's total expenses which are allocated among the
Funds under methods approved by the Board of Directors (Trustees) of each Fund.
In addition, each Fund bears its own direct expenses such as legal, auditing and
custodian fees.
 
                                        8
<PAGE>   60
 
   
     The Fund's Officers are also Officers and employees of Vanguard. No Officer
or employee owns, or is permitted to own, any securities of any external adviser
for the Funds.
    
 
     The Vanguard Group adheres to a Code of Ethics established pursuant to Rule
17j-1 under the Investment Company Act of 1940. The Code is designed to prevent
unlawful practices in connection with the purchase or sale of securities by
persons associated with Vanguard. Under Vanguard's Code of Ethics certain
officers and employees of Vanguard who are considered access persons are
permitted to engage in personal securities transactions. However, such
transactions are subject to procedures and guidelines substantially similar to
those recommended by the mutual fund industry and approved by the U.S.
Securities and Exchange Commission.
 
   
     The Vanguard Group was established and operates under a Funds' Service
Agreement which was approved by the shareholders of each of the Funds. The
amounts which each of the Funds has invested are adjusted from time to time in
order to maintain the proportionate relationship between each Fund's relative
net assets and its contribution to Vanguard's capital. At November 30, 1996, the
Fund had contributed capital of $1,445,000 to Vanguard, representing 7.2% of
Vanguard's capitalization. The Funds' Service Agreement provides as follows: (a)
each Vanguard Fund may invest up to .40% of its current assets in Vanguard, and
(b) there is no other limitation on the amount that each Vanguard Fund may
contribute to Vanguard's capitalization.
    
 
   
     MANAGEMENT  Corporate management and administrative services include: (1)
executive staff; (2) accounting and financial; (3) legal and regulatory; (4)
shareholder account maintenance; (5) monitoring and control of custodian
relationships; (6) shareholder reporting, and (7) review and evaluation of
advisory and other services provided to the Funds by third parties. During the
fiscal year ended November 30, 1996, the Fund's share of Vanguard's actual net
costs of operation relating to management and administrative services (including
transfer agency) totaled approximately $32,343,000.
    
 
     DISTRIBUTION  Vanguard provides all distribution and marketing activities
for the Funds in the Group. Vanguard Marketing Corporation, a wholly-owned
subsidiary of The Vanguard Group, Inc., acts as Sales Agent for shares of the
Funds, in connection with any sales made directly to investors in the states of
Florida, Missouri, New York, Ohio, Texas and such other states as it may be
required.
 
     The principal distribution expenses are for advertising, promotional
materials and marketing personnel. Distribution services may also include
organizing and offering to the public, from time to time, one or more new
investment companies which will become members of the Group. The Directors and
Officers of Vanguard determine the amount to be spent annually on distribution
activities, the manner and amount to be spent on each Fund, and whether to
organize new investment companies.
 
   
     One half of the distribution expenses of a marketing and promotional nature
is allocated among the Funds based upon their relative net assets. The remaining
one half of these expenses is allocated among the Funds based upon each Fund's
sales for the preceding 24 months relative to the total sales of the Funds as a
Group, provided, however, that no Fund's aggregate quarterly rate of
contribution for distribution expenses of a marketing and promotional nature
shall exceed 125% of the average distribution expense rate for the Group, and
that no Fund shall incur annual distribution expenses in excess of .20 of 1% of
its average month end net assets. During the fiscal year ended November 30,
1996, the Fund paid approximately $2,818,000, of the Group's distribution and
marketing expenses.

staff are paid by the Funds utilizing these services.
 
                     REMUNERATION OF DIRECTORS AND OFFICERS
 
   
     The Fund pays each Director, who is not also an Officer an annual fee plus
travel and other expenses incurred in attending Board meetings. The Fund's
Officers and employees are paid by Vanguard which, in turn, is reimbursed by the
Fund, and each other Fund in the Group, for its proportionate share of Officers'
and employees' salaries and retirement benefits. For the fiscal year ended
November 30, 1996, the Fund's proportionate share of remuneration for all
Officers as a group was approximately $-- and its proportionate share of the
amounts contributed to the retirement plans of all Officers as a group was
approximately $10,800.
    
 
   
     The following table provides detailed information with respect to the
amounts paid or accrued for the Directors and Officers of the Fund for whom the

                          INVESTMENT ADVISORY SERVICES
 
   
     The Fund employs Wellington Management Company, LLP (WMC) under an
investment advisory agreement dated March 1, 1996 to manage the investment and
reinvestment of the assets of the Fund and to continuously review, supervise and
administer the Fund's investment program. WMC discharges its responsibilities
subject to the control of the Officers and Directors of the Fund.
    
 
     The Fund pays WMC a Basic Fee at the end of each fiscal quarter, calculated
by applying a quarterly rate, based on the following annual percentage rates, to
the Fund's average month-end net assets for the quarter:

       applying the quarterly rate based on the Annual Basic Fee Rate using
       average assets over the same 36-month period over which the
       performance is measured.
 
   
     The new incentive penalty fee will not be fully operable until the quarter
ending February 28, 1999. Until that date, a "blended" fee rate consisting of
varying percentages of (i) the performance adjustment based on the schedule set
forth above (the "new rate"), and (ii) the performance adjustment based on the
schedule set forth in the previous investment advisory agreement((1)) (the
"previous rate") as follows:
    
 
   
          1. QUARTER ENDING MAY 31, 1997.  41.6% of the incentive/penalty fee
     shall be calculated according to the new rate and 58.4% of the
     incentive/penalty fee shall be calculated according to the previous rate.
    
 
   
          2. QUARTER ENDING AUGUST 31, 1997.  50% of the incentive/penalty fee
     shall be calculated according to the new rate and 50% of the
     incentive/penalty fee shall be calculated according to the previous rate.
    
 
   
          3. QUARTER ENDING NOVEMBER 30, 1997.  58.4% of the incentive/penalty
     fee shall be calculated according to the new rate and 41.6% of the
     incentive/penalty fee shall be calculated according to the previous rate.
    
 
   
          4. QUARTER ENDING FEBRUARY 28, 1998.  67% of the incentive/penalty fee
     shall be calculated according to the new rate and 33% of the
     incentive/penalty fee shall be calculated according to the previous rate.
    
 
   
          5. QUARTER ENDING MAY 31, 1988.  75% of the incentive/penalty fee
     shall be calculated according to the new rate and 25% of the
     incentive/penalty fee shall be calculated according to the previous rate.
    
 
   
          6. QUARTER ENDING AUGUST 31, 1998.  83.4% of the incentive/penalty fee
     shall be calculated according to the new rate and 16.6% of the
     incentive/penalty fee shall be calculated according to the previous rate.
    
 
   
          7. QUARTER ENDING NOVEMBER 30, 1998.  91.7% of the incentive/penalty
     fee shall be calculated according to the new rate and 8.3% of the
     incentive/penalty fee shall be calculated according to the previous rate.
    
 
   
          8. QUARTER ENDING FEBRUARY 28, 1999.  New rate fully operable.
    
 
- ---------------
(1) The previous incentive/penalty fee structure provided that the Basic Fee be
    increased or decreased by an amount equal to .02% per annum (.005% per
    quarter) of the average month-end assets of the Fund if the Fund's
    investment performance for the thirty-six months preceding the end of the
    quarter is six percentage points or more above or below, respectively, the
    investment record of the Salomon Brothers High- Grade Corporate Bond Index.

     The present agreement continues until February 28, 1998. The agreement is
renewable thereafter, for successive one-year periods, only if each renewal is
specifically approved by a vote of the Fund's Board of Directors, including the
affirmative votes of a majority of the directors who are not parties to the
contract or "interested persons" (as defined in the Investment Company Act of
1940) of any such party, cast in person at a meeting called for the purpose of
considering such approval. The agreement is automatically terminated if
assigned, and may be terminated without penalty at any time (1) by vote of the
Board of Directors of the Fund on 60 days' written notice to WMC, or (2) by WMC
upon 90 days' written notice to the Fund.
 
     The Fund's Board of Directors may, without the approval of shareholders,
provide for:
 
          A. The employment of a new investment adviser pursuant to the terms of
     a new advisory agreement, either as a replacement for an existing adviser
     or as an additional adviser.
 
          B. A change in the terms of an advisory agreement.
 
          C. The continued employment of an existing adviser on the same
     advisory contract terms where a contract has been assigned because of a
     change in control of the adviser.
 
     Any such change will only be made upon not less than 30 days' prior written
notice to shareholders, which shall include the information concerning the
adviser that would have normally been included in a proxy statement.
 
     The agreement is automatically terminated if assigned, and may be
terminated without penalty at any time (1) by vote of the Board of Directors of
the Fund on 60 days' written notice to WMC, or (2) by WMC upon 90 days' written
notice to the Fund.
 
   
     Because WMC provides only investment advisory services to the Fund and has
no control over the Fund's expenses, WMC has not undertaken to guarantee
expenses of the Fund. The Officers of the Fund have worked out alternative
arrangements with state authorities which require an expense guarantee.
    
 
   
     DESCRIPTION OF WMC.  WMC is a Massachusetts limited liability partnership
of which the following persons are managing partners: Robert W. Doran, Duncan M.
McFarland, and John R. Ryan.
    
 
                             PORTFOLIO TRANSACTIONS
 
     The investment advisory agreement authorizes WMC (with the approval of the
Fund's Board of Directors) to select the brokers or dealers that will execute
the purchases and sales of portfolio securities for the Fund and directs WMC to
use its best efforts to obtain the best available price and most favorable
execution as to all transactions for the Fund. WMC has undertaken to execute
each investment transaction at a price and commission which provides the most
favorable total cost or proceeds reasonably obtainable under the circumstances.
 
     In placing portfolio transactions, WMC will use its best judgment to choose
the broker most capable of providing the brokerage services necessary to obtain
best available price and most favorable execution. The full range and quality of
brokerage services available will be considered in making these determinations.
In those instances where it is reasonably determined that more than one broker
can offer the brokerage services needed to obtain the best available price and
most favorable execution, consideration may be given to those brokers which
supply investment research and statistical information and provide other
services in addition to execution services to the Fund and/or WMC. WMC considers
such information useful in the performance of its obligations under the
agreement but is unable to determine the amount by which such services may
reduce its expenses.
 
     The investment advisory agreement also incorporates the concepts of Section
28(e) of the Securities Exchange Act of 1934 by providing that, subject to the
approval of the Fund's Board of Directors, WMC may cause the Fund to pay a
broker-dealer which furnishes brokerage and research services a higher
commission than that which might be charged by another broker-dealer for
effecting the same transaction; provided that such commission is deemed
reasonable in terms of either that particular transaction or the overall
responsibilities of WMC to the Fund and the other Funds in the Group.
 
                                       12
<PAGE>   64
 
     Currently, it is the Fund's policy that WMC may at times pay higher
commissions in recognition of brokerage services felt necessary for the
achievement of better execution of certain securities transactions that
otherwise might not be available. WMC will only pay such higher commissions if
it believes this to be in the best interest of the Fund. Some brokers or dealers
who may receive such higher commissions in recognition of brokerage services
related to execution of securities transactions are also providers of research
information to WMC and/or the Fund. However, WMC has informed the Fund that it
will not pay higher commission rates specifically for the purpose of obtaining
research services.
 
     Since the Fund does not market its shares through intermediary brokers or
dealers, it is not the Fund's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be through such firms.
However, the Fund may place portfolio orders with qualified broker-dealers who
recommend the Fund to other clients, or who act as agent in the purchase of the
Fund's shares for their clients, and may, when a number of brokers and dealers
can provide comparable best price and execution on a particular transaction,
consider the sale of Fund shares by a broker or dealer in selecting among
qualified broker-dealers.
 
   
     During the fiscal years ended November 30, 1994, 1995 and 1996 the Fund
paid $2,583,152, $2,478,087 and $5,563,124 in brokerage commissions,
respectively. These fees were paid pursuant to the terms of a previous
investment advisory agreement that called for a lower rate of fees.
    
 
     Some securities considered for investment by the Fund may also be
appropriate for other Funds and/or clients served by WMC. If purchase or sale of
securities consistent with the investment policies of the Fund and one or more
of these other Funds or clients served by WMC are considered at or about the
same time, transactions in such securities will be allocated among the several
Funds and clients in a manner deemed equitable by WMC.

has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,

such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceedings) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

1. Average Annual Total Return (As of November 30, 1996)
        P (1 + T)n = ERV
    
 
   
<TABLE>
<S>          <C>     <C>
     Where:  P = a hypothetical initial payment of $1,000
             T = average annual total return
             N = number of years
             ERV = ending redeemable value at the end of the period
    EXAMPLE:
      One Year
           P =   $1,000
           T =   +21.26%
           N =   1
         ERV =   $1,212.60
    Five Years
           P =   $1,000
           T =   +15.83%
           N =   5
         ERV =   $2,085.12
    Ten Years
           P =   $1,000
           T =   +12.67%
           N =   10
         ERV =   $3,296.48

2. YIELD (30 Days Ended November 30, 1996)
    
 
   
<TABLE>
          <C>              <S>      <C>
                           a - b
               Yield = 2[( c X d    + 1)(6) - 1]
        Where:   a = dividends and interest paid during the period
                 b = expense dollars during the period (net of reimbursements)
                 c = the average daily number of shares outstanding during the period
                 d = the maximum offering price per share on the last day of the period
 
    Example     a = $56,356,015.34
                b = $3,892,327.83
                c = 580,944,206.512
                d = $28.34
             Yield = 3.85%
