INVESTMENT
OBJECTIVE AND
POLICIES
                      Vanguard/Windsor Fund (the "Fund") is an open-end
                      diversified investment company that seeks to provide
                      long-term growth of capital and income by investing
                      primarily in common stocks. The Fund's secondary objective
                      is to provide current income. There can be no assurance
                      that the Fund will achieve these objectives. Shares of the
                      Fund are neither insured nor guaranteed by any agency of
                      the U.S. Government, including the FDIC.
 
                      The Fund is an independent series of Vanguard/Windsor
                      Funds, Inc. (the "Company"). The Company is currently
                      offering shares of two series. This Prospectus relates to
                      the Vanguard/Windsor Fund series only.
- --------------------------------------------------------------------------------
 
OPENING AN
ACCOUNT               Currently, shares of the Fund are not being offered or
                      sold to new investors. Current shareholders of the Fund
                      may make additional investments of up to $25,000 during
                      calendar year 1996. See "Opening an Account and Purchasing
                      Shares" for additional information.
 
                      The Fund is offered on a no-load basis (i.e., there are no
                      sales commissions or 12b-1 fees). However, the Fund incurs
                      expenses for investment advisory, management,
                      administrative, and distribution services.

YIELD AND
TOTAL RETURN          From time to time the Fund may advertise its yield and
                      total return. Both yield and total return figures are
                      based on historical earnings and are not intended to
                      indicate future performance. The "total return" of the
                      Fund refers to the average annual compounded rates of
                      return over one-, five- and ten-year periods or for the
                      life of the Fund (as stated in the advertisement) that
                      would equate an initial amount invested at the beginning
                      of a stated period to the ending redeemable value of the
                      investment, assuming the reinvestment of all dividend and
                      capital gains distributions.
 
                      In accordance with industry guidelines set forth by the
                      U.S. Securities and Exchange Commission, the "30-day
                      yield" of the Fund is calculated daily by dividing the net
                      investment income per share earned during a 30-day period
                      by the net asset value per share on the last day of the
                      period. Net investment income includes interest and
                      dividend income earned on the Fund's securities and is net
                      of all expenses and all recurring and nonrecurring charges
                      that have been applied to all shareholder accounts. The
                      yield calculation assumes that the net investment income
                      earned over 30 days is compounded monthly for six months
                      and then annualized. Methods used to calculate advertised
                      yields are standardized for all stock and bond mutual
                      funds. However, these methods differ from the accounting
                      methods used by the Fund to maintain its books and
                      records, and so the advertised 30-day yield may not fully
                      reflect the income paid to an investor's account or the
                      yield reported in the Fund's reports to shareholders.

INVESTMENT
OBJECTIVES
THE FUND SEEKS TO
PROVIDE LONG-TERM
GROWTH OF CAPITAL
AND INCOME            The objective of the Fund is to provide long-term growth
                      of capital and income. The Fund's secondary objective is
                      to provide current income. There can be no assurance that
                      the Fund will achieve these objectives.
 
                      These investment objectives are fundamental and so cannot
                      be changed without the approval of a majority of the
                      Fund's shareholders.
 
- --------------------------------------------------------------------------------
 
INVESTMENT
POLICIES
THE FUND INVESTS
PRIMARILY IN
COMMON STOCKS         The Fund invests primarily in common stocks, which are
                      selected principally on the basis of fundamental
                      investment value. Crucial to the valuation process is the
                      relationship of a company's underlying earning power and
                      dividend payout to the market price of its stock. The
                      Fund's holdings usually are characterized by relatively
                      low price-earnings ratios and meaningful income yields. At
                      the time of purchase, many of the Fund's securities are
                      considered to be undervalued or overlooked by the market.
                      The Fund is managed without regard to tax ramifications.
 
                      Although the Fund invests primarily in common stocks, it
                      may invest in money market instruments, fixed-income
                      securities, convertible securities and other equity
                      securities, such as preferred stock. The Fund reserves the
                      right to hold money market instruments and fixed-income
                      securities in whatever proportion the adviser deems
                      appropriate for temporary defensive purposes. The Fund may
                      also invest in stock futures contracts and options and in
                      foreign securities to a limited extent. See
                      "Implementation of Policies" for a description of these
                      investment practices of the Fund.
 
                      The Fund is responsible for voting the shares of all
                      securities it holds.
 
                      The investment policies of the Fund are not fundamental
                      and so may be changed by the Board of Directors without
                      shareholder approval.
- --------------------------------------------------------------------------------
 
INVESTMENT RISKS
THE FUND IS SUBJECT
TO MARKET RISK        As a mutual fund investing primarily in common stocks, the
                      Fund is subject to MARKET RISK -- i.e., the possibility
                      that common stock prices will decline over short or even
                      extended periods. The U.S. stock market has tended to be
                      cyclical, with periods when common stock prices generally
                      rise and periods when prices generally decline.
 
                      To illustrate the volatility of stock prices, the
                      following table sets forth the extremes for stock market
                      returns as well as the average return for the period from
                      1926 to 1995, as measured by the Standard & Poor's 500
                      Composite Stock Price Index.

                      As shown, common stocks have provided annual total returns
                      (capital appreciation plus dividend income) averaging
                      +10.7% for all 10-year periods from 1926 to 1995.

                      While this average return can be used as a guide for
                      setting reasonable expectations for future stock market
                      returns, it may not be useful for forecasting future
                      returns in any particular period, as stock returns are
                      quite volatile from year to year.
 
                      This table of U.S. stock market returns should not be
                      viewed as a representation of future returns for the Fund
                      or the U.S. stock market. The illustrated returns
                      represent historical investment performance, which may be
                      a poor guide to future returns. Also, stock market indexes
                      such as the S&P 500 are based on unmanaged portfolios of
                      securities before transaction costs and other expenses.
                      Such costs will reduce the relative investment performance
                      of the Fund and other "real world" portfolios. Finally,
                      the Fund is likely to differ in portfolio composition from
                      broad stock market averages, and so the Fund's performance
                      should not be expected to mirror the returns provided by a
                      specific index.
 
THE FUND IS ALSO
SUBJECT TO
MANAGER RISK          The investment adviser manages the Fund according to the
                      traditional methods of "active" investment management,
                      which involve the buying and selling of securities based
                      upon economic, financial and market analysis and
                      investment judgment. MANAGER RISK refers to the
                      possibility that the Fund's investment adviser may fail to
                      execute the Fund's investment strategy effectively. As a
                      result, the Fund may fail to achieve its stated objective.
- --------------------------------------------------------------------------------
 
WHO SHOULD
INVEST

LONG-TERM INVESTORS
SEEKING GROWTH OF
CAPITAL AND INCOME    The Fund is intended for investors who are seeking growth
                      of capital and income. Although the Fund's secondary
                      objective is to provide current income, investors should
                      not consider the Fund a substitute for fixed-income
                      investments. The Fund is intended to be a long-term
                      investment vehicle and is not designed to provide
                      investors with a means of speculating on short-term market
                      movements. Investors who engage in excessive account
                      activity generate additional costs which are borne by all
                      of the Fund's shareholders. In order to minimize such
                      costs, the Fund has adopted the following policies. The
                      Fund reserves the right to reject any purchase request
                      (including exchange purchases from other Vanguard
                      portfolios) that is reasonably deemed to be disruptive to
                      efficient portfolio management, either because of the
                      timing of the investment or previous excessive trading by
                      the investor. Additionally, the Fund has adopted exchange
                      privilege limitations as described in the section
                      "Exchange Privilege Limitations." Finally, the Fund
                      reserves the right to suspend the offering of its shares.
 
                      No assurance can be given that the Fund will attain its
                      objectives or that shareholders will be protected from the
                      risk of loss that is inherent in equity investing.
                      Investors may wish to reduce the potential risk of
                      investing in the Fund by purchasing shares on a regular,
                      periodic basis (dollar-cost averaging) rather than making
                      an investment in one lump sum.
 
                      Investors should not consider the Fund a complete
                      investment program. Most investors should maintain
                      diversified holdings of securities with different risk
                      characteristics -- including common stocks, bonds and
                      money market instruments. Investors may also wish to
                      complement an investment in the Fund with other types of
                      common stock investments.

IMPLEMENTATION
OF POLICIES
THE FUND MAY INVEST
IN SHORT-TERM FIXED
INCOME SECURITIES     In addition to investing primarily in equity securities,
                      the Fund follows a number of additional investment
                      practices to achieve its objectives.
 
                      Although it normally seeks to remain substantially fully
                      invested in equity securities, the Fund may invest in
                      certain short-term fixed income securities. Such
                      securities may be used temporarily to invest uncommitted
                      cash balances, to maintain liquidity to meet shareholder
                      redemptions, or to take a temporarily defensive position
                      against a potential stock market decline. No more than 35%
                      of the Fund's assets will be committed to short-term fixed
                      income securities for purposes other than taking a
                      temporary defensive position. These securities include:
                      obligations of the United States government and its
                      agencies or instrumentalities; commercial paper, bank
                      certificates of deposit, and bankers' acceptances; and
                      repurchase agreements collateralized by these securities.
                      In addition, the Fund may, on occasion, invest a small
                      portion of its assets in bonds with ratings below
                      investment grade when selected issues are believed to
                      offer prospective returns competitive with equity
                      securities.
 
                      A repurchase agreement is a means of investing monies for
                      a short period. In a repurchase agreement, a seller -- a
                      U.S. commercial bank or recognized U.S. securities
                      dealer -- sells securities to the Fund and agrees to
                      repurchase the securities at the Fund's cost plus interest
                      within a specified period (normally one day). In these
                      transactions, the securities purchased by the Fund will
                      have a total value equal to or in excess of the value of
                      the repurchase agreement, and will be held by the Fund's
                      Custodian Bank until repurchased.
 
THE FUND MAY INVEST
IN SECURITIES OF
FOREIGN ISSUERS       The Fund may invest up to 20% of its assets in foreign
                      securities and may engage in currency transactions with
                      respect to such investments. Securities of foreign issuers
                      may trade in U.S. or foreign securities markets.
                      Securities of foreign issuers may involve investment risks
                      that are different from those of domestic issuers. Such
                      risks include the effect of foreign economic policies and
                      conditions, future political and economic developments,
                      and the possible imposition of exchange controls or other
                      foreign governmental restrictions on foreign debt issuers.
                      There may also be less publicly available information
                      about a foreign issuer than a domestic issuer of
                      securities. Foreign issuers are generally not subject to
                      the uniform accounting, auditing and financial reporting
                      standards that apply to domestic issuers. Foreign debt
                      markets may be characterized by lower liquidity, greater
                      price volatility, and higher transactions costs.
                      Additionally, it may be difficult to obtain or enforce a
                      legal judgment in a foreign court.
 
THE FUND MAY LEND
ITS SECURITIES        The Fund may lend its investment securities to qualified
                      institutional investors for either short-term or long-term
                      periods for the purpose of realizing additional income.
                      Loans of securities by the Fund will be collateralized by
                      cash, letters of credit, or securities issued or 
                      guaranteed by the U.S. Government or its agencies. The 
                      collateral will equal at least 100% of the current market
                      value of the loaned securities.

BORROWING             The Fund may borrow money, subject to the restrictions
                      described on page 8 in Investment Limitations, for
                      temporary or emergency purposes, including the meeting of
                      redemption requests which might otherwise require the
                      untimely disposition of securities.
    
 
PORTFOLIO TURNOVER IS
NOT EXPECTED TO
EXCEED 100%           Although it generally seeks to invest for the long term,
                      the Fund retains the right to sell securities irrespective
                      of how long they have been held. It is anticipated that
                      the annual portfolio turnover of the Fund will not exceed
                      100%. A turnover rate of 100% would occur, for example, if
                      all of the securities of the Fund were replaced within one
                      year.
 
DERIVATIVE
INVESTING
                      Derivatives are instruments whose values are linked to or
                      derived from an underlying security or index. The most
                      common and conventional types of derivative securities are
                      futures and options.
 
THE FUND MAY INVEST
IN DERIVATIVE
SECURITIES
                      The Fund may invest in futures contracts and options, but
                      only to a limited extent. Specifically, the Fund may enter
                      into futures contracts provided that not more than 5% of
                      its assets are required as a futures contract deposit; in
                      addition, the Fund may enter into futures contracts and
                      options transactions only to the extent that obligations
                      under such contracts or transactions represent not more
                      than 20% of the Fund's assets.
 
                      Futures contracts and options may be used for several
                      common fund management strategies: to maintain cash
                      reserves while simulating full investment, to facilitate
                      trading, to reduce transaction costs, or to seek higher
                      investment returns when a specific futures contract is
                      priced more attractively than other futures contracts or
                      the underlying security or index. While futures contracts
                      and options can be used as leveraged investments, the Fund
                      may not use futures or options transactions to leverage
                      its net assets.
 
                      For example, in order to remain fully invested in stocks
                      while maintaining liquidity to meet potential shareholder
                      redemptions, the Fund may invest a portion of its assets
                      in a stock futures contract. Because futures contracts
                      only require a small initial margin deposit, the Fund
                      would then be able to maintain a cash reserve for
                      potential redemptions, while at the same time remaining
                      fully invested. Also, because the transaction costs of
                      futures and options may be lower than the costs of
                      investing in stocks directly, it is expected that the use
                      of futures contracts and options may reduce the Fund's
                      total transaction costs.
 
                      The Fund may use futures contracts for bona fide "hedging"
                      purposes. In executing a hedge, a manager sells, for
                      example, stock index futures to protect against a decline
                      in the stock market. As such, if the market drops, the
                      value of the futures position will rise, thereby
                      offsetting the decline in value of the Fund's stock
                      holdings.

FUTURES CONTRACTS
AND OPTIONS POSE
CERTAIN RISKS
                      The primary risks associated with the use of futures
                      contracts and options are: (i) imperfect correlation
                      between the change in market value of the stocks held by
                      the Fund and the prices of futures contracts and options;
                      and (ii) possible lack of a liquid secondary market for a
                      futures contract and the resulting inability to close a
                      futures position prior to its maturity date. The risk of
                      imperfect correlation will be minimized by investing in
                      those contracts whose price fluctuations are expected to
                      resemble those of the Fund's underlying securities. The
                      risk that the Fund will be unable to close out a futures
                      position will be minimized by entering into such
                      transactions on a national exchange with an active and
                      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 (or gain) to the
                      investor. When investing in futures contracts, the Fund
                      will segregate cash or cash equivalents in the amount of
                      the underlying obligation.

INVESTMENT
LIMITATIONS
THE FUND HAS ADOPTED
CERTAIN FUNDAMENTAL
LIMITATIONS           The Fund has adopted certain limitations on its investment
                      practices. Specifically, the Fund will not:
 
                      (a) with respect to 75% of the value of its 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 total
                          assets of the Fund would be invested in the securities
                          of such issuer;
 
                      (b) invest more than 25% of its assets in any one
                          industry; and
 
                      (c) borrow money, except that the Fund may borrow from
                          banks (or through reverse repurchase agreements), for
                          temporary or emergency (not leveraging) purposes,
                          including the meeting of redemption requests which
                          might otherwise require the untimely disposition of
                          securities, in an amount not exceeding 10% of the
                          value of the net assets of the Fund (including the
                          amount borrowed and the value of any outstanding
                          reverse repurchase agreements) at the time the
                          borrowing is made. Whenever borrowings exceed 5% of
                          the value of the net assets of the Fund, the Fund will
                          not make any additional investments.
 
                      These investment limitations are considered at the time
                      investment securities are purchased. The investment
                      limitations described here and in the Statement of
                      Additional Information may be changed only with the
                      approval of a majority of the Fund's shareholders.

MANAGEMENT OF
THE FUND
VANGUARD ADMINISTERS
AND DISTRIBUTES
THE FUND              The Fund is a member of The Vanguard Group of Investment
                      Companies, a family of more than 30 investment companies
                      with more than 90 distinct investment portfolios and total
                      assets in excess of $180 billion. 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 certain Vanguard funds. As a result of
                      Vanguard's unique corporate structure, the Vanguard funds
                      have costs substantially lower than those of most
                      competing mutual funds. In 1995, the average expense ratio
                      (annual costs including advisory fees divided by total net
                      assets) for the Vanguard funds amounted to approximately
                      .31% compared to an average of 1.11% for the mutual fund
                      industry (data provided by Lipper Analytical Services).
 
                      The Officers of the Fund manage its day-to-day operations
                      and are responsible to the Fund's Board of Directors. The
                      Directors set broad policies for the Fund and choose its
                      Officers. A list of the Directors and Officers of the Fund
                      and a statement of their present positions and principal
                      occupations during the past five years can be found in the
                      Statement of Additional Information.
 
                      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.
 
                      Vanguard provides distribution and marketing services to
                      the funds. The funds are available on a no-load basis
                      (i.e., there are no sales commissions or 12b-1 fees).
                      However, each fund bears its share of the Group's
                      distribution costs.

INVESTMENT
ADVISER
WELLINGTON
MANAGEMENT
COMPANY SERVES AS
ADVISER TO THE FUND   The Fund has entered into an investment advisory agreement
                      with Wellington Management Company ("WMC"), 75 State

                      investment and reinvestment of Vanguard/Windsor Fund's
                      assets and continuously reviews, supervises and
                      administers the Fund's investment program. WMC discharges
                      its responsibilities subject to the control of the
                      Officers and Directors of the Fund.
 
                      WMC is a professional investment counseling firm which
                      globally provides investment services to investment
                      companies, institutions, and individuals. Among the
                      clients of WMC are more than 10 investment companies of
                      The Vanguard Group. As of December 31, 1995, WMC held
                      investment management authority with respect to more than
                      $108 billion of assets. WMC and its predecessor
                      organizations have provided investment advisory services
                      to investment companies since 1931 and to investment
                      counseling clients since 1960.

                      Charles T. Freeman, Senior Vice President of WMC serves as
                      portfolio manager of the Fund. Mr. Freeman joined WMC in
                      1969 and served as assistant portfolio manager of the Fund
                      until his appointment as portfolio manager in January of
                      1996. Mr. Freeman is supported by research and other
                      investment services provided by the professional staff of
                      WMC.
 
                      John B. Neff, the Fund's previous portfolio manager,
                      retired from WMC effective December 31, 1995, after 31
                      years of service as the Fund's portfolio manager. Mr. Neff
                      serves as an adviser to WMC and continues to work with the
                      firm's investment professionals, including the portfolio
                      managers of all Vanguard funds for which WMC serves as
                      adviser.
 
                      WMC earns a basic advisory fee, calculated by applying the
                      following annual percentage rates to the average month-end
                      net assets of the Fund:

                      The basic fee paid to the Adviser may be increased or
                      decreased by applying an adjustment based on the Fund's
                      investment performance. Such formula provides for an
                      increase or decrease of the basic fee in an amount equal
                      to .10% per annum (.025% per quarter) of the average
                      month-end net assets of the Fund if the Fund's investment
                      performance for the thirty-six months preceding the end of
                      the quarter is twelve percentage points or more above or

                      annum (.0125% per quarter) if the Fund's investment
                      performance for such thirty-six months is six or more but
                      less than twelve percentage points above or below,
                      respectively, the investment record of the S&P Index for
                      the same period.
 
                      During the fiscal year ended October 31, 1995, the total
                      advisory fees paid by the Fund to WMC represented an
                      effective annual rate of .16% of the Fund's average net
                      assets before an increase of .06% based upon the
                      investment performance.
 
                      The investment advisory agreement authorizes WMC to select
                      brokers or dealers to execute purchases and sales of the
                      Fund's portfolio securities, and directs the adviser to
                      use its best efforts to obtain the best available price
                      and most favorable execution with respect to all
                      transactions. The full range and quality of brokerage
                      services available are considered in making these
                      determinations.
 
                      The Fund has authorized WMC to pay higher commissions in
                      recognition of brokerage services felt necessary for the
                      achievement of better execution, provided the adviser
                      believes this to be in the best interest of the Fund.
                      Although the Fund does not market its shares through
                      intermediary brokers or dealers, the Fund may place orders
                      with qualified broker-dealers who recommend the Fund to
                      clients if the

                      Officers of the Fund believe that the quality of the
                      transaction and the commission are comparable to what they
                      would be with other qualified brokerage firms.
 
                      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; and (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 of the Fund, which shall include
                      substantially the information concerning the adviser that
                      would have normally been included in a proxy statement.

PERFORMANCE
RECORD                The table below provides investment results for the Fund
                      for several periods throughout the Fund's lifetime. The
                      results shown represent the Fund's "total return"
                      investment performance, which assumes the reinvestment of
                      all capital gains and income dividends, annualized for the
                      indicated periods. Also included is comparative
                      information with respect to the unmanaged Standard &
                      Poor's 500 Composite Stock Price Index, a widely used
                      barometer of stock market activity, and the Consumer Price
                      Index, a statistical measure of changes in the prices of
                      goods and services. The table does not make any allowance
                      for federal, state or local income taxes which
                      shareholders must pay on a current basis.
 
                      The results shown should not be considered a
                      representation of the total return from an investment made
                      in the Fund today. This information is provided to help
                      investors better understand the Fund and may not provide a
                      basis for comparison with other investments or mutual
                      funds which use a different method to calculate
                      performance.

DIVIDENDS, CAPITAL
GAINS AND TAXES

THE FUND PAYS
SEMI-ANNUAL
DIVIDENDS AND
AND CAPITAL GAINS
ANNUALLY              The Fund expects to pay dividends from ordinary income
                      semi-annually. Capital gains distributions, if any, will
                      be made annually.
 
                      In addition, in order to satisfy certain distribution
                      requirements of the Tax Reform Act of 1986, the Fund may
                      declare special year-end dividend and capital gains
                      distributions during December. Such distributions, if
                      received by shareholders by January 31, are deemed to have
                      been paid by the Fund and received by shareholders on
                      December 31 of the prior year.
 
                      Dividend and capital gains distributions may be
                      automatically reinvested or received in cash. See
                      "Choosing a Distribution Option" for a description of
                      these distributions methods.
 
                      The Fund intends to continue to qualify for taxation as a
                      "regulated investment company" under the Internal Revenue
                      Code so that it will not be subject to federal tax to the
                      extent its income is distributed to shareholders.
                      Dividends paid by the Fund from net investment income,
                      whether received in cash or reinvested in additional
                      shares, will be taxable to shareholders as ordinary
                      income. For corporate investors, dividends from net
                      investment income will generally qualify in part for the
                      corporate dividends received deduction. However, the
                      portion of the dividends so qualified depends on the
                      aggregate taxable qualifying dividend income received by
                      the Fund from domestic (U.S.) sources.
 
                      Distributions paid by the Fund from long-term capital
                      gains, whether received in cash or reinvested in
                      additional shares, are taxable as long-term capital gains,
                      regardless of the length of time you have owned shares in
                      the Fund. Capital gains distributions are made when the
                      Fund realizes net capital gains on sales of portfolio
                      securities during the year. The Fund does not seek to
                      realize any particular amount of capital gains during a
                      year; rather, realized gains are a by-product of portfolio
                      management activities. Consequently, capital gains
                      distributions may be expected to vary considerably from
                      year to year; there will be no capital gains distributions
                      in years when the Fund realizes net capital losses.
 
                      Note that if you accept capital gains distributions in
                      cash instead of reinvesting them in additional shares, you
                      are in effect reducing the capital at work for you in the
                      Fund. Also, keep in mind that if you purchase shares in
                      the Fund shortly before the record date for a dividend or
                      capital gains distribution, a portion of your investment
                      will be returned to you as a taxable distribution,
                      regardless of whether you are reinvesting your
                      distributions or receiving them in cash.
 
                      The Fund will notify you annually as to the tax status of
                      dividend and capital gains distributions paid by the Fund.
 
A CAPITAL GAIN OR
LOSS MAY BE REALIZED
UPON EXCHANGE
OR REDEMPTION         A sale of shares of the Fund is a taxable event and may
                      result in a capital gain or loss. A capital gain or loss
                      may be realized from an ordinary redemption of shares or
                      an exchange of shares between two mutual funds (or two
                      portfolios of a mutual fund).
 
                      Dividend distributions, capital gains distributions, and
                      capital gains or losses from redemptions and exchanges may
                      be subject to state and local taxes.

                      The Fund is required to withhold 31% of taxable dividends,
                      capital gains distributions, and redemptions paid to
                      shareholders who have not complied with IRS taxpayer
                      identification regulations. You may avoid this withholding
                      requirement by certifying on your Account Registration
                      Form your proper Social Security or Employer
                      Identification number and certifying that you are not
                      subject to backup withholding.
 
                      The Fund has obtained a Certificate of Authority to do
                      business as a foreign corporation in Pennsylvania and does
                      business and maintains an office in that state. In the
                      opinion of counsel, the shares of the Fund are exempt from
                      Pennsylvania personal property taxes.
 
                      The tax discussion set forth above is included for general
                      information only. Prospective investors should consult
                      their own tax advisers concerning the tax consequences of
                      an investment in the Fund. The Fund is managed without
                      regard to tax ramifications.

THE SHARE PRICE
OF THE FUND           The Fund's share price or "net asset value" per share is
                      determined by dividing the total market value of the
                      Fund's investments and other assets, less any liabilities,
                      by the number of outstanding shares of the Fund. Net asset
                      value is determined as of the regular close of the New
                      York Stock Exchange (generally 4:00 p.m. Eastern time) on
                      each day the exchange is open for trading.
 
                      Portfolio securities that are listed on a securities
                      exchange are valued at the latest quoted sales prices.
                      Price information on listed securities is taken from the
                      exchange where the security is primarily traded.
                      Securities which are listed on an exchange and which are
                      not traded on the valuation date are valued at the mean of
                      the latest quoted bid and asked prices. Unlisted
                      securities for which market quotations are readily
                      available are valued at the latest quoted bid price.
                      Short-term instruments (those with remaining maturities of
                      60 days or less) are valued at cost, plus or minus any
                      amortized discount or premium, which approximates market.
                      Other assets and securities for which market quotations
                      are not readily available or which are restricted as to
                      sale are valued by such methods as the Board of Directors
                      deems in good faith to reflect fair value. Securities may
                      be valued on the basis of prices provided by a pricing
                      service when such prices are believed to reflect the fair
                      market value of such securities. The prices provided by a
                      pricing service may be determined without regard to bid or
                      last sale prices of each security but take into account
                      institutional-size transactions in similar groups of
                      securities as well as any developments related to specific
                      securities.
 
                      The Fund's share price can be found daily in the mutual
                      fund listings of most major newspapers under the heading
                      of Vanguard.

GENERAL
INFORMATION           The Company is a Maryland corporation. The Articles of
                      Incorporation permit the Directors to issue 2,200,000,000
                      shares of common stock, with a one cent par value. The
                      Board of Directors has the power to designate one or more
                      classes ("series") of shares of common stock and to
                      classify and reclassify any unissued shares with respect
                      to such series. Currently the Company is offering shares
                      of two series.

                      The shares of each series of the Company are fully paid
                      and non-assessable; have no preference as to conversion,
                      exchange, dividends, retirement or other features; and
                      have no pre-emptive rights. Such shares have
                      non-cumulative voting rights, meaning that the holders of
                      more than 50% of the shares voting for the election of
                      Directors can elect 100% of the Directors if they so
                      choose.
 
                      Annual meetings of shareholders will not be held except as
                      required by the Investment Company Act of 1940 and other
                      applicable law. An annual meeting will be held to vote on
                      the removal of a Director or Directors of the Company if
                      requested in writing by the holders of not less than 10%
                      of the outstanding shares of the Company.
 
                      All securities and cash are held by State Street Bank and
                      Trust Company, Boston, MA. The Vanguard Group, Inc.,
                      Valley Forge, PA, serves as the Fund's Transfer and
                      Dividend Disbursing Agent. Price Waterhouse LLP, serves as
                      independent accountants for the Fund and will audit its
                      financial statements annually. The Fund is not involved in
                      any litigation.

                      sold to new investors. Current shareholders of the Fund
                      may make additional investments, but the aggregate amount
                      of such investments made during the calendar year may not
                      exceed $25,000.
 
                      Regular annual contributions to existing Vanguard/Windsor
                      Fund retirement accounts are being accepted. For IRAs, you
                      may make annual contributions up to the applicable tax law
                      limit ($2,000), as well as asset transfers and rollovers,
                      but the total of such purchases may not exceed $25,000.
                      For other retirement plans, total purchases generally may
                      not exceed $25,000. However, annual contributions to
                      retirement plans sponsored by Vanguard may be higher if
                      permitted under the tax laws.
 
                      Because of the risks associated with common stock
                      investments, the Fund is intended to be a long-term
                      investment vehicle and is not designed to provide
                      investors with a means of speculating on short-term stock
                      market movements. Consequently the Fund reserves the right
                      to reject any specific purchase (or exchange purchase)
                      request. The Fund also reserves the right to suspend the
                      offering of shares for a period of time.
 
                      Vanguard will not accept third-party checks to purchase
                      shares of the Fund. Please be sure your purchase check is
                      made payable to The Vanguard Group-22.
 
                      The Fund's shares are purchased at the next-determined net
                      asset value after your investment has been received. The
                      Fund is offered on a no-load basis (i.e., there are no
                      sales commissions or 12b-1 fees).
 
ADDITIONAL
INVESTMENTS           Subsequent investments by current shareholders may be made
                      only by mail ($100 minimum), wire ($1,000 minimum),
                      exchange from another Vanguard Fund account, or Vanguard
                      Fund Express.

                      remittance form attached to your Fund confirmation
                      statement. Please make your check payable to The Vanguard

CHOOSING A
DISTRIBUTION
OPTION                You must select one of three distribution options:
 
                      1. AUTOMATIC REINVESTMENT OPTION -- Both dividends and
                         capital gains distributions will be reinvested in
                         additional Fund shares. This option will be selected
                         for you automatically unless you specify one of the
                         other options.
 
                      2. CASH DIVIDEND OPTION -- Your dividends will be paid in
                         cash and your capital gains will be reinvested in
                         additional Fund shares.
 
                      3. ALL CASH OPTION -- Both dividend and capital gains
                         distributions will be paid in cash.
 
                      You may change your option by calling our Client Services
                      Department (1-800-662-2739).
 
                      In addition, an option to invest your cash dividends
                      and/or capital gains distributions in another Vanguard
                      Fund account is available. Please call our Client Services
                      Department (1-800-662-2739) for information. You may also
                      elect Vanguard Dividend Express which allows you to

TAX CAUTION

INVESTORS SHOULD ASK
ABOUT THE TIMING OF
CAPITAL GAINS AND
DIVIDEND DISTRIBUTIONS
BEFORE INVESTING      Under federal tax laws, the Fund is required to distribute
                      net capital gains and dividend income to Fund
                      shareholders. These distributions are made to all
                      shareholders who own Fund shares as of the distribution's
                      record date, regardless of how long the shares have been
                      owned. Purchasing shares just prior to the record date
                      could have a significant impact on your tax liability for
                      the year. For example, if you purchase shares immediately
                      prior to the record date of a sizable capital gain or
                      income dividend distribution, you will be assessed taxes
                      on the amount of the capital gain and/or dividend
                      distribution later paid even though you owned the Fund
                      shares for just a short period of time. (Taxes are due on
                      the distributions even if the dividend or gain is
                      reinvested in additional Fund shares.) While the total
                      value of your investment will be the same after the
                      distribution -- the amount of the distribution will offset
                      the drop in the net asset value of the shares -- you
                      should be aware of the tax implications the timing of your
                      purchase may have.
 
                      Prospective investors should, therefore, inquire about
                      potential distributions before investing. The Fund's
                      annual capital gains distribution normally occurs in
                      December, while income dividends are generally paid
                      semi-annually in June and December. For additional
                      information on distributions and taxes, see the section
                      titled "Dividends, Capital Gains, and Taxes."

IMPORTANT ACCOUNT
INFORMATION

ESTABLISHING OPTIONAL
SERVICES              The easiest way to establish optional Vanguard services on
                      your account is to select the options you desire when you
                      complete your Account Registration Form. IF YOU WISH TO
                      ADD SHAREHOLDER OPTIONS LATER, YOU MAY NEED TO PROVIDE
                      VANGUARD WITH ADDITIONAL INFORMATION AND A SIGNATURE
                      GUARANTEE. PLEASE CALL OUR CLIENT SERVICES DEPARTMENT
                      (1-800-662-2739) FOR FURTHER ASSISTANCE.
 
SIGNATURE GUARANTEES  For our mutual protection, we may require a signature
                      guarantee on certain written transaction requests. A
                      signature guarantee verifies the authenticity of your
                      signature and may be obtained from banks, brokers and any
                      other guarantors that Vanguard deems acceptable. A
                      SIGNATURE GUARANTEE CANNOT BE PROVIDED BY A NOTARY PUBLIC.
 
CERTIFICATES          Share certificates will be issued upon request. If a
                      certificate is lost, you may incur an expense to replace
                      it.
 
BROKER-DEALER
PURCHASES             If you purchase shares in Vanguard Funds through a
                      registered broker-dealer or investment adviser, the
                      broker-dealer or investment adviser may charge a service
                      fee.
 
CANCELLING TRADES     The Fund will not cancel any trade (e.g., purchase,
                      exchange or redemption) believed to be authentic, received
                      in writing or by telephone, once the trade request has
                      been received.

WHEN YOUR
ACCOUNT WILL
BE CREDITED           Your trade date is the date on which your account is
                      credited. If your purchase is made by check, Federal Funds
                      wire or exchange, and is received by the regular close of
                      the New York Stock Exchange (generally 4:00 p.m. Eastern
                      time), your trade date is the date of receipt. If your
                      purchase is received after the close of the Exchange, your
                      trade date is the next business day. Your shares are
                      purchased at the net asset value determined on your trade
                      date.
 
                      In order to prevent lengthy processing delays caused by
                      the clearing of foreign checks, Vanguard will only accept
                      a foreign check which has been drawn in U.S. dollars and
                      has been issued by a foreign bank with a U.S.
                      correspondent bank. The name of the U.S. correspondent
                      bank must be printed on the face of the foreign check.

SELLING YOUR
SHARES                You may withdraw any portion of the funds in your account

                      initiate a request by writing or by telephoning. Your
                      redemption proceeds are normally mailed within two
                      business days after the receipt of the request in Good
                      Order.

                      Vanguard Fund account to your bank account according to
                      the schedule you have selected. The SPECIAL REDEMPTION
                      option lets you move money from your Vanguard account to
                      your bank account on your request. To establish Fund

                      another Vanguard Fund account. Please see "Exchanging Your
                      Shares" for details.

IMPORTANT REDEMPTION
INFORMATION           Shares purchased by check or Fund Express may be redeemed
                      at any time. However, your redemption proceeds will not be
                      paid until payment for the purchase is collected, which
                      may take up to ten calendar days.
- --------------------------------------------------------------------------------
 
DELIVERY OF
REDEMPTION PROCEEDS   If you choose to close your Vanguard/Windsor account
                      through a redemption, you will not be able to open another
                      account at a later date, since Windsor Fund is currently
                      closed to new investors. But, if you choose to close your
                      account through an exchange to another Vanguard portfolio,
                      your account can be reopened for up to one year.
 
                      Redemption requests received by telephone prior to the
                      regular close of the New York Stock Exchange (generally
                      4:00 p.m. Eastern time) are processed on the day of
                      receipt and the redemption proceeds are normally sent on
                      the following business day.
 
                      Redemption requests received by telephone after the close
                      of the Exchange are processed on the business day
                      following receipt and the proceeds are normally sent on
                      the second business day following receipt.
 
                      Redemption proceeds must be sent to you within seven days
                      of receipt of your request in Good Order, except as
                      described above in Important Redemption Information.
 
                      If you experience difficulty in making a telephone
                      redemption during periods of drastic economic or market
                      changes, your redemption request may be made by regular or
                      express mail. It will be implemented at the net asset
                      value next determined after your request has been received
                      by Vanguard in Good Order. The Fund reserves the right to
                      revise or terminate the telephone redemption privilege at
                      any time.
 
                      The Fund may suspend the redemption right 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 the Board of Directors determines that it would be
                      detrimental to the best interests of the Fund's remaining
                      shareholders to make payment in cash, the Fund may pay
                      redemption proceeds in whole or in part by a distribution
                      in kind of readily marketable securities.

VANGUARD'S AVERAGE
COST STATEMENT        If you make a redemption from a qualifying account,
                      Vanguard will send you an Average Cost Statement which
                      provides you with the tax basis of the shares you
                      redeemed. Please see "Statements and Reports" for
                      additional information.
- --------------------------------------------------------------------------------
 
   
LOW BALANCE
FEE AND MINIMUM
ACCOUNT BALANCE
REQUIREMENT           Due to the relatively high cost of maintaining smaller
                      accounts, the Fund will automatically deduct a $10 annual
                      fee from non-retirement accounts with balances falling
                      below $2,500 ($1,000 for Uniform Gifts/Transfers to Minors
                      Act accounts). This fee deduction will occur mid-year,
                      beginning in 1996. The fee generally will be waived for
                      investors whose aggregate Vanguard assets exceed $50,000.
                      In addition, the Fund reserves the right to liquidate any
                      non-retirement account that is below the minimum initial
                      investment amount. If at any time your total investment
                      does not have a value of at least $3,000, you may be
                      notified that your account is below the Fund's minimum
                      account balance requirement. You would then be allowed 60
                      days to make an additional investment before the account
                      is liquidated. Proceeds would be promptly paid to the
                      registered shareholder.
    
 
                      Vanguard will not liquidate your account if it has fallen
                      below $3,000 solely as a result of declining markets
                      (i.e., a decline in a Fund's net asset value).

IMPORTANT EXCHANGE
INFORMATION           Before you make an exchange, you should consider the
                      following:
 
                      - Please read the Fund's prospectus before making an
                        exchange. For a copy and for answers to any questions
                        you may have, call our Investor Information Department
                        (1-800-662-7447).
 
                      - An exchange is treated as a redemption and a purchase;
                        therefore, you could realize a taxable gain or loss on
                        the transaction.
 
                      - Exchanges are accepted only if the registrations and the
                        Taxpayer Identification numbers of the two accounts are
                        identical.
 
                      - New accounts are not currently accepted in the Fund or
                        Vanguard/PRIMECAP Fund.
 
                      - The shares to be exchanged must be on deposit and not
                        held in certificate form.
 
                      - The redemption price of shares redeemed by exchange is
                        the net asset value next determined after Vanguard has
                        received any required documents in Good Order.
 
                      - When opening a new account by exchange, you must meet
                        the minimum investment requirement of the new Fund. You
                        cannot open a new account in the Fund by exchange.
 
                      Every effort will be made to maintain the exchange
                      privilege. However, the Fund reserves the right to revise
                      or terminate its provisions, or to limit the amount of or
                      reject any exchange, as deemed necessary, at any time.
- --------------------------------------------------------------------------------
 
EXCHANGE
PRIVILEGE
LIMITATIONS           The Fund's exchange privilege is not intended to afford
                      shareholders a way to speculate on short-term movements in
                      the market. Accordingly, in order to prevent excessive use
                      of the exchange privilege that may potentially disrupt the
                      management of the Fund and increase transaction costs, the
                      Fund has established a policy of limiting excessive
                      exchange activity.
 
                      Exchange activity generally will not be deemed excessive
                      if limited to TWO SUBSTANTIVE EXCHANGE REDEMPTIONS (AT
                      LEAST 30 DAYS APART) from the Fund during any twelve month
                      period. Notwithstanding these limitations, the Fund
                      reserves the right to reject any purchase request
                      (including exchange purchases from other Vanguard
                      portfolios) that is reasonably deemed to be disruptive to
                      efficient portfolio management.

IMPORTANT
INFORMATION
ABOUT TELEPHONE
TRANSACTIONS          The ability to initiate redemptions (except wire
                      redemptions) and exchanges by telephone is automatically
                      established on your account unless you request in writing
                      that telephone transactions on your account not be
                      permitted.
 
                      To protect your account from losses resulting from
                      unauthorized or fraudulent telephone instructions,
                      Vanguard adheres to the following security procedures:
 
                      1. SECURITY CHECK.  To request a transaction by telephone,
                         the caller must know (i) the name of the Portfolio;
                         (ii) the 10-digit account number; (iii) the exact name
                         and address used in the registration; and (iv) the
                         Social Security or Employer Identification number
                         listed on the account.
 
                                       21
<PAGE>   24
 
                      2. PAYMENT POLICY.  The proceeds of any telephone
                         redemption by mail will be made payable to the
                         registered shareowners and mailed to the address of
                         record, only.
 
                      Neither the Fund nor Vanguard will be responsible for the
                      authenticity of transaction instructions received by
                      telephone, provided that reasonable security procedures
                      have been followed. Vanguard believes that the security
                      procedures described above are reasonable, and that if
                      such procedures are followed, you will bear the risk of
                      any losses resulting from unauthorized or fraudulent
                      telephone transactions on your account. If Vanguard fails
                      to follow reasonable security procedures, it may be liable
                      for any losses resulting from unauthorized or fraudulent
                      telephone transactions on your account.
- --------------------------------------------------------------------------------
 
TRANSFERRING
REGISTRATION          You may transfer the registration of any of your Fund
                      shares to another person, provided that the amount of each
                      transfer equals at least $3,000 for non-retirement and
                      $2,000 for IRAs, by completing a transfer form and sending
                      it to: VANGUARD FINANCIAL CENTER, P.O. BOX 1110, VALLEY
                      FORGE, PA 19482. The request must be in Good Order. Before

                      Department (1-800-662-2739) for full instructions.

                      available for most taxable accounts opened since January

                      The purpose of this table is to assist you in
                      understanding the various costs and expenses that an
                      investor would bear directly or indirectly as a
                      shareholder in the Fund.
 
                      The following example illustrates the expenses that a
                      shareholder would incur on a $1,000 investment over
                      various periods, assuming (1) a 5% annual rate of return
                      and (2) redemption at the end of each period. As noted in
                      the table above, the Fund charges no redemption fees of
                      any kind.

YIELD AND
TOTAL RETURN          From time to time the Fund may advertise its yield and
                      total return. Both yield and total return figures are
                      based on historical earnings and are not intended to
                      indicate future performance. The "total return" of the
                      Fund refers to the average annual compounded rates of
                      return over one-, five- and ten-year periods or for the
                      life of the Fund (as stated in the advertisement) that
                      would equate an initial amount invested at the beginning
                      of a stated period to the ending redeemable value of the
                      investment, assuming the reinvestment of all dividend and
                      capital gains distributions.
 
                      In accordance with industry guidelines set forth by the
                      U.S. Securities and Exchange Commission, the "30-day
                      yield" of the Fund is calculated daily by dividing the net
                      investment income per share earned during a 30-day period
                      by the net asset value per share on the last day of the
                      period. Net investment income includes interest and
                      dividend income earned on the Fund's securities and is net
                      of all expenses and all recurring and nonrecurring charges
                      that have been applied to all shareholder accounts. The
                      yield calculation assumes that the net investment income
                      earned over thirty days is compounded monthly for six
                      months and then annualized. Methods used to calculate
                      advertised yields are standardized for all stock and bond
                      mutual funds. However, these methods differ from the
                      accounting methods used by the Fund to maintain its books
                      and records, and so the advertised 30-day yield may not
                      fully reflect the income paid to an investor's account or
                      the yield reported in the Fund's reports to shareholders.

INVESTMENT
OBJECTIVES
THE FUND SEEKS TO
PROVIDE LONG-TERM
GROWTH OF CAPITAL
AND INCOME            The objective of the Fund is to provide long-term growth
                      of capital and income. The Fund's secondary objective is
                      to provide current income. There can be no assurance that
                      the Fund will achieve these objectives.
 
                      These investment objectives are fundamental and so cannot
                      be changed without the approval of a majority of the
                      Fund's shareholders.

INVESTMENT
POLICIES
THE FUND INVESTS
PRIMARILY IN
COMMON STOCKS         The Fund invests primarily in common stocks, which are
                      selected principally on the basis of fundamental
                      investment value. Crucial to the valuation process is the
                      relationship of a company's underlying earning power and
                      dividend payout to the market price of its stock. The
                      Fund's holdings usually are characterized by relatively
                      low price-earnings ratios and meaningful income yields. At
                      the time of purchase, many of the Fund's securities are
                      considered to be undervalued or overlooked by the market.
                      The Fund is managed without regard to tax ramifications.
 
                      Although the Fund invests primarily in common stocks, it
                      may invest in money market instruments, fixed-income
                      securities, convertible securities and other equity
                      securities, such as preferred stock. The Fund reserves the
                      right to hold money market instruments and fixed-income
                      securities in whatever proportion the adviser deems
                      appropriate for temporary defensive purposes. The Fund may
                      also invest in stock futures contracts and options and in
                      foreign securities to a limited extent.
                      See "Implementation of Policies" for a description of
                      these investment practices
                      of the Fund.
 
                      The Fund is responsible for voting the shares of all
                      securities it holds.
 
                      The investment policies of the Fund are not fundamental
                      and so may be changed by the Board of Directors without
                      shareholder approval.
- --------------------------------------------------------------------------------
 
INVESTMENT RISKS
THE FUND IS SUBJECT
TO MARKET RISK
                      As a mutual fund investing primarily in common stocks, the
                      Fund is subject to MARKET RISK -- i.e., the possibility
                      that common stock prices will decline over short or even
                      extended periods. The U.S. stock market has tended to be
                      cyclical, with periods when common stock prices generally
                      rise and periods when prices generally decline.
 
                      To illustrate the volatility of stock prices, the
                      following table sets forth the extremes for stock market
                      returns as well as the average return for the period from
                      1926 to 1995, as measured by the Standard & Poor's 500
                      Composite Stock Price Index.

                      As shown, common stocks have provided annual total returns
                      (capital appreciation plus dividend income), averaging
                      +10.7% for all 10-year periods from 1926 to 1995.

                      While this average return can be used as a guide for
                      setting reasonable expectations for future stock market
                      returns, it may not be useful for forecasting future
                      returns in any particular period, as stock returns are
                      quite volatile from year to year.
 
                      This table of U.S. stock market returns should not be
                      viewed as a representation of future returns for the Fund
                      or the U.S. stock market. The illustrated returns
                      represent historical investment performance, which may be
                      a poor guide to future returns. Also, stock market indexes
                      such as the S&P 500 are based on unmanaged portfolios of
                      securities before transaction costs and other expenses.
                      Such costs will reduce the relative investment performance
                      of the Fund and other "real world" portfolios. Finally,
                      the Fund is likely to differ in portfolio composition from
                      broad stock market averages, and so the Fund's performance
                      should not be expected to mirror the returns provided by a
                      specific index.
 
THE FUND IS ALSO
SUBJECT TO
MANAGER RISK          The investment adviser manages the Fund according to the
                      traditional methods of "active" investment management,
                      which involve the buying and selling of securities based
                      upon economic, financial and market analysis and
                      investment judgment. MANAGER RISK refers to the
                      possibility that the Fund's investment adviser may fail to
                      execute the Fund's investment strategy effectively. As a
                      result, the Fund may fail to achieve its stated objective.
- --------------------------------------------------------------------------------
 
WHO SHOULD
INVEST
LONG-TERM INVESTORS
SEEKING GROWTH OF
CAPITAL AND INCOME    The Fund is intended for investors who are seeking growth
                      of capital and income. Although the Fund's secondary
                      objective is to provide current income, investors should
                      not consider the Fund a substitute for fixed-income
                      investments. The Fund is intended to be a long-term
                      investment vehicle and is not designed to provide
                      investors with a means of speculating on short-term market
                      movements. Investors who engage in excessive account
                      activity generate additional costs which are borne by all
                      of the Fund's shareholders. In order to minimize such
                      costs the Fund has adopted certain policies. The Fund
                      reserves the right to reject any purchase request
                      (including exchange purchases from other Vanguard
                      portfolios) that is reasonably deemed to be disruptive to
                      efficient portfolio management, either because of the
                      timing of the investment or previous excessive trading by
                      the investor. Additionally, the Fund reserves the right to
                      suspend the offering of its shares.
 
                      No assurance can be given that the Fund will attain its
                      objectives or that shareholders will be protected from the
                      risk of loss that is inherent in equity investing.
                      Investors may wish to reduce the potential risk of
                      investing in the Fund by purchasing shares on a regular,
                      periodic basis (dollar-cost-averaging) rather than making
                      an investment in one lump sum.
 
                      Investors should not consider the Fund a complete
                      investment program. Most investors should maintain
                      diversified holdings of securities with different risk
                      characteristics -- including common stocks, bonds and
                      money market instruments. Investors may also wish to
                      complement an investment in the Fund with other types of
                      common stock investments.

IMPLEMENTATION
OF POLICIES
THE FUND MAY INVEST
IN SHORT-TERM FIXED
INCOME SECURITIES     In addition to investing primarily in equity securities,
                      the Fund follows a number of additional investment
                      practices to achieve its objectives.
 
                      Although it normally seeks to remain substantially fully
                      invested in equity securities, the Fund may invest in
                      certain short-term fixed income securities. Such
                      securities may be used temporarily to invest uncommitted
                      cash balances, to maintain liquidity to meet shareholder
                      redemptions, or to take a temporarily defensive position
                      against a potential stock market decline. No more than 35%
                      of the Fund's assets will be committed to short-term fixed
                      income securities for purposes other than taking a
                      temporary defensive position. These securities include:
                      obligations of the United States government and its
                      agencies or instrumentalities; commercial paper, bank
                      certificates of deposit, and bankers' acceptances; and
                      repurchase agreements collateralized by these securities.
                      In addition, the Fund may, on occasion, invest a small
                      portion of its assets in bonds with ratings below
                      investment grade when selected issues are believed to
                      offer prospective returns competitive with equity
                      securities.
 
                      A repurchase agreement is a means of investing monies for
                      a short period. In a repurchase agreement, a seller -- a
                      U.S. commercial bank or recognized U.S. securities
                      dealer -- sells securities to the Fund and agrees to
                      repurchase the securities at the Fund's cost plus interest
                      within a specified period (normally one day). In these
                      transactions, the securities purchased by the Fund will
                      have a total value equal to or in excess of the value of
                      the repurchase agreement, and will be held by the Fund's
                      Custodian Bank until repurchased.
 
THE FUND MAY INVEST
IN SECURITIES OF
FOREIGN ISSUERS
                      The Fund may invest up to 20% of its assets in foreign
                      securities and may engage in currency transactions with
                      respect to such investments. Securities of foreign issuers
                      may trade in U.S. or foreign securities markets.
                      Securities of foreign issuers may involve investment risks
                      that are different from those of domestic issuers. Such
                      risks include the effect of foreign economic policies and
                      conditions, future political and economic developments,
                      and the possible imposition of exchange controls or other
                      foreign governmental restrictions on foreign debt issuers.
                      There may also be less publicly available information
                      about a foreign issuer than a domestic issuer of
                      securities. Foreign issuers are generally not subject to
                      the uniform accounting, auditing and financial reporting
                      standards that apply to domestic issuers. Foreign debt
                      markets may be characterized by lower liquidity, greater
                      price volatility, and higher transactions costs.
                      Additionally, it may be difficult to obtain or enforce a
                      legal judgment in a foreign court.
 
THE FUND MAY LEND
ITS SECURITIES        The Fund may lend its investment securities to qualified
                      institutional investors for either short-term or long-term
                      periods for the purpose of realizing additional income.
                      Loans of securities by the Fund will be collateralized by
                      cash, letters of credit, or securities issued or
                      guaranteed by the U.S. Government or its agencies. The
                      collateral will equal at least 100% of the current market
                      value of the loaned securities.
 
   
BORROWING             The Fund may borrow money, subject to the restrictions
                      described on page 8 in Investment Limitations, for
                      temporary or emergency purposes, including the

PORTFOLIO TURNOVER IS
NOT EXPECTED TO
EXCEED 100%           Although it generally seeks to invest for the long term,
                      the Fund retains the right to sell securities irrespective
                      of how long they have been held. It is anticipated that
                      the annual portfolio turnover of the Fund will not exceed
                      100%. A turnover rate of 100% would occur, for example, if
                      all of the securities of the Fund were replaced within one
                      year.
 
DERIVATIVE
INVESTING             Derivatives are instruments whose values are linked to or
                      derived from an underlying security or index. The most
                      common and conventional types of derivative securities are
                      futures and options.
 
THE FUND MAY INVEST
IN DERIVATIVE
SECURITIES            The Fund may invest in futures contracts and options, but
                      only to a limited extent. Specifically, the Fund may enter
                      into futures contracts provided that not more than 5% of
                      its assets are required as a futures contract deposit; in
                      addition, the Fund may enter into futures contracts and
                      options transactions only to the extent that obligations
                      under such contracts or transactions represent not more
                      than 20% of the Fund's assets.
 
                      Futures contracts and options may be used for several
                      common fund management strategies: to maintain cash
                      reserves while simulating full investment, to facilitate
                      trading, to reduce transaction costs, or to seek higher
                      investment returns when a specific futures contract is
                      priced more attractively than other futures contracts or
                      the underlying security or index. While futures contracts
                      and options can be used as leveraged investments, the Fund
                      may not use futures or options transactions to leverage
                      its net assets.
 
                      For example, in order to remain fully invested in stocks
                      while maintaining liquidity to meet potential shareholder
                      redemptions, the Fund may invest a portion of its assets
                      in a stock futures contract. Because futures contracts
                      only require a small initial margin deposit, the Fund
                      would then be able to maintain a cash reserve for
                      potential redemptions, while at the same time remaining
                      fully invested. Also, because the transaction costs of
                      futures and options may be lower than the costs of
                      investing in stocks directly, it is expected that the use
                      of futures contracts and options may reduce the Fund's
                      total transaction costs.
 
                      The Fund may use futures contracts for bona fide "hedging"
                      purposes. In executing a hedge, a manager sells, for
                      example, stock index futures to protect against a decline
                      in the stock market. As such, if the market drops, the
                      value of the futures position will rise, thereby
                      offsetting the decline in value of the Fund's stock
                      holdings.
 
FUTURES CONTRACTS
AND OPTIONS POSE
CERTAIN RISKS         The primary risks associated with the use of futures
                      contracts and options are: (i) imperfect correlation
                      between the change in market value of the stocks held by
                      the Fund and the prices of futures contracts and options;
                      and (ii) possible lack of a liquid secondary market for a
                      futures contract and the resulting inability to close a
                      futures position prior to its maturity date. The risk of
                      imperfect correlation will be minimized by investing in
                      those contracts whose price fluctuations are expected to
                      resemble those of the Fund's underlying securities. The
                      risk that the Fund will be
 
                                        7
<PAGE>   38
 
                      unable to close out a futures position will be minimized
                      by entering into such transactions on a national exchange
                      with an active and 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 (or gain) to the
                      investor. When investing in futures contracts, the Fund
                      will segregate cash or cash equivalents in the amount of
                      the underlying obligation.

INVESTMENT
LIMITATIONS
THE FUND HAS ADOPTED
CERTAIN FUNDAMENTAL
LIMITATIONS           The Fund has adopted certain limitations on its investment
                      practices. Specifically, the Fund will not:
 
                      (a) with respect to 75% of the value of its 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 total
                          assets of the Fund would be invested in the securities
                          of such issuer;
 
                      (b) invest more than 25% of its assets in any one
                          industry; and
 
                      (c) borrow money, except that the Fund may borrow from
                          banks (or through reverse repurchase agreements), for
                          temporary or emergency (not leveraging) purposes,
                          including the meeting of redemption requests which
                          might otherwise require the untimely disposition of
                          securities, in an amount not exceeding 10% of the
                          value of the net assets of the Fund (including the
                          amount borrowed and the value of any outstanding
                          reverse repurchase agreements) at the time the
                          borrowing is made. Whenever borrowings exceed 5% of
                          the value of the net assets of the Fund, the Fund will
                          not make any additional investments.
 
                      These investment limitations are considered at the time
                      investment securities are purchased. The investment
                      limitations described here and in the Statement of
                      Additional Information are fundamental and may be changed
                      only with the approval of a majority of the Fund's
                      shareholders.

MANAGEMENT OF
THE FUND
VANGUARD ADMINISTERS
AND DISTRIBUTES
THE FUND              The Fund is a member of The Vanguard Group of Investment
                      Companies, a family of more than 30 investment companies
                      with more than 90 distinct investment portfolios and total
                      assets in excess of $180 billion. 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 certain Vanguard funds. As a result of
                      Vanguard's unique corporate structure, the Vanguard funds
                      have costs substantially lower than those of most
                      competing mutual funds. In 1995, the average expense ratio
                      (annual costs including advisory fees divided by total net
                      assets) for the Vanguard funds amounted to approximately
                      .31% compared to an average of 1.11% for the mutual fund
                      industry (data provided by Lipper Analytical Services).

                      The Officers of the Fund manage its day-to-day operations
                      and are responsible to the Fund's Board of Directors. The
                      Directors set broad policies for the Fund and choose its
                      Officers. A list of the Directors and Officers of the Fund
                      and a statement of their present positions and principal
                      occupations during the past five years can be found in the
                      Statement of Additional Information.
 
                      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.
 
                      Vanguard provides distribution and marketing services to
                      the funds. The funds are available on a no-load basis
                      (i.e., there are no sales commissions or 12b-1 fees).
                      However, each fund bears its share of the Group's
                      distribution costs.

ADVISER
WELLINGTON
MANAGEMENT
COMPANY SERVES AS
ADVISER TO THE FUND   The Fund has entered into an investment advisory agreement
                      with Wellington Management Company ("WMC"), 75 State
                      Street, Boston, MA 02109, under which WMC manages the
                      investment and reinvestment of Vanguard/Windsor Fund's
                      assets and continuously reviews, supervises and
                      administers the Fund's investment program. WMC discharges
                      its responsibilities subject to the control of the
                      Officers and Directors of the Fund.
 
                      WMC is a professional investment counseling firm which
                      globally provides investment services to investment
                      companies, institutions, and individuals. Among the
                      clients of WMC are more than 10 investment companies of
                      The Vanguard Group. As of December 31, 1995 WMC held
                      investment management authority with respect to more than
                      $108 billion of assets. WMC and its predecessor
                      organizations have provided investment advisory services
                      to investment companies since 1931 and to investment
                      counseling clients since 1960.
 
                      Charles T. Freeman, Senior Vice President of WMC serves as
                      portfolio manager of the Fund. Mr. Freeman joined WMC in
                      1969 and served as assistant portfolio manager of the Fund
                      until his appointment as portfolio manager in January of
                      1996. Mr. Freeman is supported by research and other
                      investment services provided by the professional staff of
                      WMC.
 
                      John B. Neff, the Fund's previous portfolio manager,
                      retired from WMC effective December 31, 1995, after 31
                      years of service as the Fund's portfolio manager. Mr. Neff
                      serves as an adviser to WMC and continues to work with the
                      firm's investment professionals, including the portfolio
                      managers of all Vanguard funds for which WMC serves as
                      adviser.

                      The basic fee paid to the Adviser may be increased or
                      decreased by applying an adjustment based on the Fund's
                      investment performance. Such formula provides for an
                      increase or decrease of the basic fee in an amount equal
                      to .10% per annum (.025% per quarter) of the average
                      month-end net assets of the Fund if the Fund's investment
                      performance for the thirty-six months preceding the end of
                      the quarter is twelve percentage points or more above or
                      below, respectively, the investment record of the Standard
                      & Poor's 500 Composite Stock Price Index (the "S&P Index")
                      for the same period; or by an amount equal to .05% per
                      annum (.0125% per quarter) if the Fund's investment
                      performance for such thirty-six months is six or more but
                      less than twelve percentage points above or below,
                      respectively, the investment record of the S&P Index for
                      the same period.
 
                      During the fiscal year ended October 31, 1995, the total
                      advisory fees paid by the Fund to WMC represented an
                      effective annual rate of .16% of the Fund's average net
                      assets before an increase of .06% based upon investment
                      performance.
 
                      The investment advisory agreement authorized WMC to select
                      brokers or dealers to execute purchases and sales of the
                      Fund's portfolio securities, and directs the adviser to
                      use its best efforts to obtain the best available price
                      and most favorable execution with respect to all
                      transactions. The full range and quality of brokerage
                      services available are considered in making these
                      determinations.
 
                      The Fund has authorized WMC to pay higher commissions in
                      recognition of brokerage services felt necessary for the
                      achievement of better execution, provided the adviser
                      believes this to be in the best interest of the Fund.
                      Although the Fund does not market its shares through
                      intermediary brokers or dealers, the Fund may place orders
                      with qualified broker-dealers who recommend the Fund to
                      clients if the Officers of the Fund believe that the
                      quality of the transaction and the commission are
                      comparable to what they would be with other qualified
                      brokerage firms.
 
                      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; and (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 of the Fund,
                      which shall include substantially the information
                      concerning the adviser that would have normally been
                      included in a proxy statement.

PERFORMANCE
RECORD                The table below provides investment results for the Fund
                      for several periods throughout the Fund's lifetime. The
                      results shown represent the Fund's "total return"
                      investment performance, which assumes the reinvestment of
                      all capital gains and income dividends, annualized for the
                      indicated periods. Also included is comparative
                      information with respect to the unmanaged Standard &
                      Poor's 500 Composite Stock Price Index, a widely used
                      barometer of stock market activity, and the Consumer Price
                      Index, a statistical measure of changes in the prices of
                      goods and services. The table does not make any allowance
                      for federal, state, or local income taxes which
                      shareholders must pay on a current basis.
 
                      The results shown should not be considered a
                      representation of the total return from an investment made
                      in the Fund today. This information is provided to help
                      investors better understand the Fund and may not provide a
                      basis for comparison with other investments or mutual
                      funds which use a different method to calculate
                      performance.

DIVIDENDS, CAPITAL
GAINS AND TAXES
THE FUND PAYS
SEMI-ANNUAL
DIVIDENDS AND
ANY CAPITAL GAINS
ANNUALLY
                      The Fund expects to pay dividends from ordinary income
                      semi-annually. Capital gains distributions, if any, will
                      be made annually. All dividend and capital gains
                      distributions are automatically reinvested in additional
                      shares of the Fund. In order to satisfy certain
                      distribution requirements of the IRS, the Fund may also
                      declare special year-end distributions during December.
                      The Fund intends to continue to qualify for taxation as a
                      "regulated investment company" under the Internal Revenue
                      Code so that it will not be subject to federal income tax
                      to the extent that its income is distributed to its
                      shareholders.
 
                      If you utilize the Fund as an investment option in an
                      employer-sponsored retirement or savings plan, dividend
                      and capital gains distributions from the Fund generally
                      will not be subject to current taxation, but will
                      accumulate on a tax-

                      deferred basis. In general, employer-sponsored retirement
                      and savings plans are governed by a complex set of tax
                      rules. You should consult your plan administrator, the
                      plan's "Summary Plan Description," or a professional tax
                      adviser regarding the tax consequences of your
                      participation in the plan and of any plan contributions or
                      withdrawals.

THE SHARE PRICE
OF THE FUND           The Fund's share price or "net asset value" per share is
                      determined by dividing the total market value of the
                      Fund's investments and other assets, less any liabilities,
                      by the number of outstanding shares of the Fund. Net asset
                      value is determined as of the regular close of the New
                      York Stock Exchange (generally 4:00 p.m. Eastern time) on
                      each day the exchange is open for trading.
 
                      Portfolio securities that are listed on a securities
                      exchange are valued at the latest quoted sales prices.
                      Price information on listed securities is taken from the
                      exchange where the security is primarily traded.
                      Securities which are listed on an exchange and which are
                      not traded on the valuation date are valued at the mean of
                      the latest quoted bid and asked prices. Unlisted
                      securities for which market quotations are readily
                      available are valued at the latest quoted bid price.
                      Short-term instruments (those with remaining maturities of
                      60 days or less) are valued at cost, plus or minus any
                      amortized discount or premium, which approximates market.
                      Other assets and securities for which market quotations
                      are not readily available or which are restricted as to
                      sale are valued by such methods as the Board of Directors
                      deems in good faith to reflect fair value. Securities may
                      be valued on the basis of prices provided by a pricing
                      service when such prices are believed to reflect the fair
                      market value of such securities. The prices provided by a
                      pricing service may be determined without regard to bid or
                      last sale prices of each security but take into account
                      institutional-size transactions in similar groups of
                      securities as well as any developments related to specific
                      securities.
 
                      The Fund's share price can be found daily in the mutual
                      fund listings of most major newspapers under the heading
                      of Vanguard.

GENERAL
INFORMATION           The Company is a Maryland corporation. The Articles of
                      Incorporation permit the Directors to issue 2,200,000,000
                      shares of common stock, with a one cent par value. The
                      Board of Directors has the power to designate one or more
                      classes ("series") of shares of common stock and to
                      classify and reclassify any unissued shares with respect
                      to such series. Currently the Company is offering shares
                      of two series.
 
                      The shares of each series of the Company are fully paid
                      and non-assessable; have no preference as to conversion,
                      exchange, dividends, retirement or other features; and
                      have no pre-emptive rights. Such shares have
                      non-cumulative voting rights, meaning that the holders of
                      more than 50% of the shares voting for the election of
                      Directors can elect 100% of the Directors if they so
                      choose.

YIELD AND
TOTAL RETURN          From time to time the Fund may advertise its yield and
                      total return. Both yield and total return figures are
                      based on historical earnings and are not intended to
                      indicate future performance. The "total return" of the
                      Fund refers to the average annual compounded rates of
                      return over one-, five- and ten-year periods or for the
                      life of the Fund (as stated in the advertisement) that
                      would equate an initial amount invested at the beginning
                      of a stated period to the ending redeemable value of the
                      investment, assuming the reinvestment of all dividend and
                      capital gains distributions.
 
                      In accordance with industry guidelines set forth by the
                      U.S. Securities and Exchange Commission, the "30-day
                      yield" of the Fund is calculated daily by dividing the net
                      investment income per share earned during a 30-day period
                      by the net asset value per share on the last day of the
                      period. Net investment income includes interest and
                      dividend income earned on the Fund's securities, and is
                      net of all expenses and all recurring and nonrecurring
                      charges that have been applied to all shareholder
                      accounts. The yield calculation assumes that the net
                      investment income earned over 30 days is compounded
                      monthly for six months and then annualized. Methods used
                      to calculate advertised yields are standardized for all
                      stock and bond mutual funds. However, these methods differ
                      from the accounting methods used by the Fund to maintain
                      its books and records, and so the advertised 30-day yield
                      may not fully reflect the income paid to an investor's
                      account or the yield reported in the Fund's reports to
                      shareholders. Additionally, the Fund may

INVESTMENT
OBJECTIVES
THE FUND SEEKS TO
PROVIDE LONG-TERM
GROWTH OF CAPITAL
AND INCOME            The objective of the Fund is to provide long-term growth
                      of capital and income. The Fund's secondary objective is
                      to provide current income. There can be no assurance that
                      the Fund will achieve these objectives.
 
                      These investment objectives are fundamental and so cannot
                      be changed without the approval of a majority of the
                      Fund's shareholders.

INVESTMENT
POLICIES
THE FUND INVESTS
PRIMARILY IN
COMMON STOCKS         The Fund follows a flexible investment strategy,
                      emphasizing income-producing stocks which the investment
                      advisers believe to be undervalued by the market at the
                      time of purchase. Generally, these securities are
                      characterized by below-average price-earnings ratios
                      relative to the stock market, as measured by the Standard
                      & Poor's Composite Stock Price Index. The Fund is managed
                      without regard to tax ramifications.
 
                      Stocks will be selected based upon assessments of
                      statistical measures of current value (such as low
                      price-earnings and low price-to-book value ratios) and
                      future earnings prospects. Returns on such stocks can be
                      influenced by the recognition of their undervaluation by
                      other investors based on statistical measures or changes
                      in expectations regarding potential earnings and dividend
                      growth. If a stock has reached a fully-valued position as
                      determined by one of the Fund's investment advisers, the
                      stock will ordinarily be sold regardless of the time it
                      has been held and replaced by one or more securities that
                      are considered to be undervalued.
 
                      Although the Fund invests primarily in common stocks, it
                      may invest in money market instruments, fixed-income
                      securities, and other equity securities, such as preferred
                      stock. The Fund is expected, under normal circumstances,
                      to be substantially fully invested in common stocks. In
                      addition, the Fund may invest in stock futures and options
                      to a limited extent. See "Implementation of Policies" for
                      a description of these and other investment practices of
                      the Fund.
 
                      The Fund is responsible for voting the shares of all
                      securities it holds.
 
                      The investment policies of the Fund are not fundamental
                      and so may be changed by the Board of Directors without
                      shareholder approval.

INVESTMENT RISKS
THE FUND IS SUBJECT
TO MARKET RISK        As a mutual fund investing primarily in common stocks, the
                      Fund is subject to MARKET RISK -- i.e., the possibility
                      that common stock prices will decline over short or even
                      extended periods. The U.S. stock market has tended to be
                      cyclical, with periods when stock prices generally rise
                      and periods when prices generally decline.
 
                      To illustrate the volatility of stock prices, the
                      following table sets forth the extremes for stock market
                      returns as well as the average return for the period from

</TABLE>
 
                      As shown, common stocks have provided annual total returns
                      (capital appreciation plus dividend income) averaging
                      +10.7% for all 10-year periods from 1926 to 1995. While
                      this average return can be used as a guide for setting
                      reasonable expectations for future stock market returns,
                      it may not be useful for forecasting future returns in any
                      particular period, as stock returns are quite volatile
                      from year to year.
 
                      This table of U.S. stock market returns should not be
                      viewed as a representation of future returns for the Fund
                      or the U.S. stock market. The illustrated returns
                      represent historical investment performance, which may be
                      a poor guide to future returns. Also, stock market indexes
                      such as the S&P 500 are based on unmanaged portfolios of
                      securities before transaction costs and other expenses.
                      Such costs will reduce the relative investment performance
                      of the Fund and other "real world" portfolios. Finally,
                      the Fund is likely to differ in portfolio composition from
                      broad stock market averages, and so the Fund's performance
                      should not be expected to mirror the returns provided by a
                      specific index.
 
THE FUND IS ALSO
SUBJECT TO
MANAGER RISK          The investment adviser manages the Fund according to the
                      traditional methods of "active" investment management,
                      which involve the buying and selling of securities based
                      upon economic, financial and market analysis and
                      investment judgment. MANAGER RISK refers to the
                      possibility that the Fund's investment advisers may fail
                      to execute the Fund's investment strategy effectively. As
                      a result, the Fund may fail to achieve its stated
                      objective.
- --------------------------------------------------------------------------------
 
WHO SHOULD
INVEST
LONG-TERM INVESTORS
SEEKING GROWTH OF
CAPITAL AND INCOME    The Fund is intended for investors who are seeking growth
                      of capital and income. Although the Fund's secondary
                      objective is to provide current income, investors should
                      not consider the Fund a substitute for fixed-income
                      investments. The Fund is intended to be a long-term
                      investment vehicle and is not designed to provide
                      investors with a means of speculating on short-term market
                      movements. Investors who engage in excessive account
                      activity generate additional costs which are borne by all
                      of the Fund's shareholders. In order to minimize such
                      costs, the Fund has adopted the following policies. The
                      Fund reserves the right to reject any purchase request
                      (including exchange purchases from other Vanguard
                      portfolios) that is reasonably deemed to be disruptive to
                      efficient portfolio management, either because of the
                      timing of the investment or previous excessive trading by
                      the investor. Additionally the Fund has adopted exchange
                      privilege limitations as described in the section
                      "Exchange Privilege Limitations." Finally, the Fund
                      reserves the right to suspend the offering of its shares.

                      No assurance can be given that the Fund will attain its
                      objectives or that shareholders will be protected from the
                      risk of loss that is inherent in equity investing.
                      Investors may wish to reduce the potential risk of
                      investing in the Fund by purchasing shares on a regular,
                      periodic basis (dollar-cost averaging) rather than making
                      an investment in one lump sum.
 
                      Investors should not consider the Fund a complete
                      investment program. Most investors should maintain
                      diversified holdings of securities with different risk
                      characteristics -- including common stocks, bonds and
                      money market instruments. Investors may also wish to
                      complement an investment in the Fund with other types of
                      common stock investments.
- --------------------------------------------------------------------------------
 
IMPLEMENTATION
OF POLICIES           In addition to investing primarily in equity securities,
                      the Fund follows a number of additional investment
                      practices to achieve its objectives.
 
THE FUND MAY INVEST
IN SHORT-TERM FIXED
INCOME SECURITIES     Although it normally seeks to remain substantially fully
                      invested in equity securities, the Fund may invest
                      temporarily in certain short-term fixed income securities.
                      Such securities may be used to invest uncommitted cash
                      balances, to maintain liquidity to meet shareholder
                      redemptions, or to take a temporarily defensive position
                      against a potential stock market decline. No more than 35%
                      of the Fund's assets will be committed to short-term fixed
                      income securities for purposes other than taking a
                      temporary defensive position. These securities include:
                      obligations of the United States Government and its
                      agencies or instrumentalities; commercial paper, bank
                      certificates of deposit, and bankers' acceptances; and
                      repurchase agreements collateralized by these securities.
 
                      A repurchase agreement is a means of investing monies for
                      a short period. In a repurchase agreement, a seller -- a
                      U.S. commercial bank or recognized U.S. securities
                      dealer -- sells securities to the Fund and agrees to
                      repurchase the securities at the Fund's cost plus interest
                      within a specified period (normally one day). In these
                      transactions, the securities purchased by the Fund will
                      have a total value equal to or in excess of the value of
                      the repurchase agreement, and will be held by the Fund's
                      Custodian Bank until repurchased.
 
THE FUND MAY LEND
ITS SECURITIES        The Fund may lend its investment securities to qualified
                      institutional investors for either short-term or long-term
                      periods for the purpose of realizing additional income.
                      Loans of securities by the Fund will be collateralized by
                      cash, letters of credit, or securities issued or
                      guaranteed by the U.S. government or its agencies. The
                      collateral will equal at least 100% of the current market
                      value of the loaned securities.
 
   
BORROWING
                      The Fund may borrow money, subject to the restrictions
                      described on page 8 in Investment Limitations, for
                      temporary or emergency purposes, including the meeting of
                      redemption requests which might otherwise require the
                      untimely disposition of securities.

PORTFOLIO TURNOVER IS
NOT EXPECTED TO
EXCEED 100%           Although it generally seeks to invest for the long term,
                      the Fund retains the right to sell securities irrespective
                      of how long they have been held. It is anticipated that
                      the annual portfolio turnover of the Fund will not exceed
                      100%. A turnover rate of 100% would occur, for example, if
                      all of the securities of the Fund were replaced within one
                      year.
 
DERIVATIVE
INVESTING             Derivatives are instruments whose values are linked to or
                      derived from an underlying security or index. The most
                      common and conventional types of derivative securities are
                      futures and options.
 
THE FUND MAY
INVEST IN DERIVATIVE
SECURITIES            The Fund may invest in futures contracts and options, but
                      only to a limited extent. Specifically, the Fund may enter
                      into futures contracts provided that not more than 5% of
                      its assets are required as a futures contract deposit; in
                      addition, the Fund may enter into futures contracts and
                      options transactions only to the extent that obligations
                      under such contracts or transactions represent not more
                      than 20% of the Fund's assets.
 
                      Futures contracts and options may be used for several
                      common fund management strategies: to maintain cash
                      reserves while simulating full investment, to facilitate
                      trading, to reduce transaction costs, or to seek higher
                      investment returns when a specific futures contract is
                      priced more attractively than other futures contracts or
                      the underlying security or index. While futures contracts
                      and options can be used as leveraged investments, the Fund
                      may not use futures or options transactions to leverage
                      its net assets.
 
                      For example, in order to remain fully invested in stocks
                      while maintaining liquidity to meet potential shareholder
                      redemptions, the Fund may invest a portion of its assets
                      in a stock futures contract. Because futures contracts
                      only require a small initial margin deposit, the Fund
                      would then be able to maintain a cash reserve for
                      potential redemptions, while at the same time remaining
                      fully invested. Also, because the transaction costs of
                      futures and options may be lower than the costs of
                      investing in stocks directly, it is expected that the use
                      of futures contracts and options may reduce the Fund's
                      total transaction costs.
 
                      The Fund may use futures contracts for bona fide "hedging"
                      purposes. In executing a hedge, a manager sells, for
                      example, stock index futures to protect against a decline
                      in the stock market. As such, if the market drops, the
                      value of the futures position will rise, thereby
                      offsetting the decline in value of the Fund's stock
                      holdings.
 
FUTURES CONTRACTS
AND OPTIONS POSE
CERTAIN RISKS         The primary risks associated with the use of futures
                      contracts and options are: (i) imperfect correlation
                      between the change in market value of the stocks held by
                      the Fund and the prices of futures contracts and options;
                      and (ii) possible lack of a liquid secondary market for a
                      futures contract and the resulting inability to close a
                      futures position prior to its maturity date. The risk of
                      imperfect correlation will be minimized by investing in
                      those contracts whose price fluctuations are expected to
                      resemble those of the Fund's underlying securities. The
                      risk that the Fund will be unable to close out a futures
                      position will be minimized by entering into such
                      transactions on a national exchange with an active and
                      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 (or gain) to the
                      investor. When investing in futures contracts, the Fund
                      will segregate cash or cash equivalents in the amount of
                      the underlying obligation.

INVESTMENT
LIMITATIONS
THE FUND HAS ADOPTED
CERTAIN FUNDAMENTAL
LIMITATIONS           The Fund has adopted certain limitations on its investment
                      practices. Specifically, the Fund will not:
 
                      (a)  with respect to 75% of the value of its 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 total

MANAGEMENT OF
THE FUND
VANGUARD ADMINISTERS
AND DISTRIBUTES
THE FUND              The Fund is a member of The Vanguard Group of Investment
                      Companies, a family of more than 30 investment companies
                      with more than 90 distinct investment portfolios and total
                      assets in excess of $180 billion. 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 certain Vanguard funds, including Vanguard/Windsor II.
                      As a result of Vanguard's unique corporate structure, the
                      Vanguard funds have costs substantially lower than those
                      of most competing mutual funds. In 1995, the average
                      expense ratio (annual costs including advisory fees
                      divided by total net assets) for the Vanguard funds
                      amounted to approximately .31% compared to an average of
                      1.11% for the mutual fund industry (data provided by
                      Lipper Analytical Services).
 
                      The Officers of the Fund manage its day-to-day operations
                      and are responsible to the Fund's Board of Directors. The
                      Directors set broad policies for the Fund and choose its
                      Officers. A list of the Directors and Officers of the Fund

                      the past five years can be found in the Statement of
                      Additional Information.
 
                      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 net 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.
 
                      Vanguard provides distribution and marketing services to
                      the funds. The funds are available on a no-load basis
                      (i.e., there are no sales commissions or 12b-1 fees).
                      However, each fund bears its share of the Group's
                      distribution costs.

                      on an at-cost basis by Vanguard's Core Management Group.
                      BHM&S, Equinox and Tukman are not affiliated in any way
                      with Wellington Management Company, the investment adviser
                      to Vanguard/Windsor Fund.
 
                      The proportion of the net assets of the Fund managed by
                      each adviser is established by the Board of Directors and
                      may be changed in the future as circumstances warrant.
                      Currently, BHM&S manages approximately 72% of the equity
                      allocation of the Fund, Equinox and Tukman manage
                      approximately 10% each, and Vanguard's Core Management
                      Group manages approximately 8% of the Fund's equity
                      allocation. Investors will be advised of any substantive
                      change in the proportions managed by each adviser. Each
                      adviser discharges their responsibilities subject to the
                      control of the Directors and Officers.

                      Tukman earns a basic advisory fee, calculated by applying
                      the following annual percentage rates to the average
                      month-end net assets of the Fund managed by Tukman:

                      The Fund's payments to Tukman under the above schedule are
                      subject to an incentive/penalty fee arrangement which
                      compares the performance of the Fund's assets managed by
                      Tukman with the performance of the Standard & Poor's 500
                      Composite Stock Price Index. This arrangement provides for
                      the following adjustments to Tukman's basic fee.

VANGUARD'S CORE       Vanguard's Core Management Group provides investment   
MANAGEMENT GROUP      advisory services on an at-cost basis with respect to a
                      portion of the Fund's assets. The Core Management Group
                      also provides investment advisory services to several
                      Vanguard funds, including Vanguard Index Trust, Vanguard
                      Balanced Index Fund, Vanguard Horizon Fund, Vanguard
                      International Equity Index Fund, Vanguard Institutional
                      Index Fund, several indexed separate accounts, as well as
                      a portion of Vanguard/Morgan Growth Fund's assets. Total
                      assets under management by the Core Management Group were
                      approximately $33 billion as of December 31, 1995. The
                      portion of the Fund allocated to the Core Management Group
                      is managed using computerized, quantitative techniques
                      based on a value index constructed to approximate the
                      aggregate fundamental characteristics of a typical large
                      capitalization value fund, such as Vanguard/Windsor II.
                      For further information concerning the index, please refer
                      to the Statement of Additional Information. The Core
                      Management Group is supervised by the Officers of the
                      Fund.
 
AGGREGATE ADVISORY    For the fiscal year ended October 31, 1995, the aggregate
FEES PAID BY THE FUND investment advisory fees paid by the Fund to BHM&S,
                      Equinox and Tukman, represented an effective annual rate
                      of .14 of 1% of average net assets before an increase of
                      $86,000 based on performance. The investment advisory fees
                      paid by the Fund for this period to BHM&S represented an
                      effective annual rate of .14 of 1% of the average net
                      assets managed by BHM&S. The investment advisory fees paid
                      by the Fund for this period to Equinox and Tukman
                      represented an effective annual rate of .20 of 1% and .24
                      of 1% of the average net assets managed by Equinox and
                      Tukman, respectively.
 
OTHER ADVISORY        BHM&S, Equinox, Tukman and Vanguard's Core Management
INFORMATION           Group are authorized to select brokers or dealers to 
                      execute purchases and sales of the Fund's portfolio
                      securities, and directed to use their best efforts to
                      obtain the best available price and most favorable
                      execution with respect to all transactions. The full range
                      and quality of brokerage services available are considered
                      in making these determinations.
 
                      The Fund has authorized BHM&S, Equinox, Tukman and
                      Vanguard's Core Management Group to pay higher commissions
                      in recognition of brokerage services deemed necessary for
                      the achievement of better execution, provided the advisers
                      believe this to be in the best interest of the Fund.
                      Although the Fund does not market its shares through
                      intermediary brokers or dealers, the Fund may place orders
                      with qualified broker-dealers who recommend the Fund to
                      clients if the Officers of the Fund believe
 
                                       12
<PAGE>   59
 
                      that the quality of the transaction and the commission are
                      comparable to what they would be with other qualified
                      brokerage firms.
 
                      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; and (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 of the Fund, which shall include
                      substantially the information concerning the adviser that
                      would have normally been included in a proxy statement.

PERFORMANCE
RECORD                The table below provides investment results for the Fund
                      for several periods throughout the Fund's lifetime. The
                      results shown represent "total return" investment
                      performance, which assumes the reinvestment of all capital
                      gains and income dividends, annualized for the indicated
                      periods. Also included is comparative information with
                      respect to the unmanaged Standard & Poor's 500 Composite
                      Stock Price Index, a widely used barometer of stock market
                      activity, and the Consumer Price Index, a statistical
                      measure of changes in the prices of goods and services.
                      The table does not make any allowance for federal, state
                      or local income taxes which shareholders must pay on a
                      current basis.
    
 
                      The results shown should not be considered a
                      representation of the total return from an investment made
                      in the Fund today. This information is provided to help
                      investors better understand the Fund and may not provide a
                      basis of comparison with other investments or mutual funds
                      which use a different method to calculate performance.

DIVIDENDS, CAPITAL
GAINS AND TAXES       The Fund expects to pay dividends from ordinary income
                      semi-annually. Capital gains distributions, if any, will
                      be made annually.
 
THE FUND PAYS
SEMI-ANNUAL
DIVIDENDS AND
ANY CAPITAL GAINS
ANNUALLY
                      In addition, in order to satisfy certain distribution
                      requirements of the Tax Reform Act of 1986, the Fund may
                      declare special year-end dividend and capital gains
                      distributions during December. Such distributions, if
                      received by shareholders by January 31, are deemed to have
                      been paid by the Fund and received by shareholders on
                      December 31 of the prior year.
 
                      Dividend and capital gains distributions may be
                      automatically reinvested or received in cash. See
                      "Choosing a Distribution Option" for a description of
                      these distributions methods.
 
                      The Fund intends to continue to qualify for taxation as a
                      "regulated investment company" under the Internal Revenue
                      Code so that it will not be subject to federal income tax
                      to the extent its income is distributed to shareholders.
                      Dividends paid by the Fund from net investment income,
                      whether received in cash or reinvested in additional
                      shares, will be taxable to shareholders as ordinary
                      income. For corporate investors, dividends from net
                      investment income will generally qualify in part for the
                      corporate dividends received deduction. However, the
                      portion of the dividends so qualified depends on the
                      aggregate taxable qualifying dividend income received by
                      the Fund from domestic (U.S.) sources.
 
                      Distributions paid by the Fund from long-term capital
                      gains, whether received in cash or reinvested in
                      additional shares, are taxable as long-term capital gains,
                      regardless of the length of time you have owned shares in
                      the Fund. Capital gains distributions are made when the
                      Fund realizes net capital gains on sales of portfolio
                      securities during the year. The Fund does not seek to
                      realize any particular amount of capital gains during a
                      year; rather, realized gains are a by-product of portfolio
                      management activities. Consequently, capital gains
                      distributions may be expected to vary considerably from
                      year to year; there will be no capital gains distributions
                      in years when the Fund realizes net capital losses.
 
                      Note that if you accept capital gains distributions in
                      cash, instead of reinvesting them in additional shares,
                      you are in effect reducing the capital at work for you in
                      the Fund. Also, keep in mind that if you purchase shares
                      in the Fund shortly before the record date for a dividend
                      or capital gains distribution, a portion of your
                      investment will be returned to you as a taxable
                      distribution, regardless of whether you are reinvesting
                      your distributions or receiving them in cash.
 
                      The Fund will notify you annually as to the tax status of
                      dividend and capital gains distributions paid by the Fund.
 
A CAPITAL GAIN OR
LOSS MAY BE REALIZED
UPON EXCHANGE
OR REDEMPTION         A sale of shares of the Fund is a taxable event, and may
                      result in a capital gain or loss. A capital gain or loss
                      may be realized from an ordinary redemption of shares or
                      an exchange of shares between two mutual funds (or two
                      portfolios of a mutual fund).
 
                      Dividend distributions, capital gains distributions, and
                      capital gains or losses from redemptions and exchanges may
                      be subject to state and local taxes.

                      The Fund is required to withhold 31% of taxable dividends,
                      capital gains distributions, and redemptions paid to
                      shareholders who have not complied with IRS taxpayer
                      identification regulations. You may avoid this withholding
                      requirement by certifying on your Account Registration
                      Form your proper Social Security or Employer
                      Identification number and certifying that you are not
                      subject to backup withholding.
 
                      The Fund has obtained a Certificate of Authority to do
                      business as a foreign corporation in Pennsylvania and does
                      business and maintains an office in that state. In the
                      opinion of counsel, the shares of the Fund are exempt from
                      Pennsylvania personal property taxes.
 
                      The tax discussion set forth above is included for general
                      information only. Prospective investors should consult
                      their own tax advisers concerning the tax consequences of
                      an investment in the Fund. The Fund is managed without
                      regard to tax ramifications.

THE SHARE PRICE
OF THE FUND           The Fund's share price or "net asset value" per share is
                      determined by dividing the total market value of the
                      Fund's investments and other assets, less any liabilities,
                      by the number of outstanding shares of the Fund. Net asset
                      value is determined as of the regular close of the New
                      York Stock Exchange (generally 4:00 p.m. Eastern time) on
                      each day the exchange is open for trading.
 
                      Portfolio securities that are listed on a securities
                      exchange are valued at the latest quoted sales prices.
                      Price information on listed securities is taken from the
                      exchange where the security is primarily traded.
                      Securities which are listed on an exchange and which are
                      not traded on the valuation date are valued at the mean of
                      the latest quoted bid and asked prices. Unlisted
                      securities for which market quotations are readily
                      available are valued at the latest quoted bid price.
                      Short-term instruments (those with remaining maturities of
                      60 days or less) are valued at cost, plus or minus any
                      amortized discount or premium, which approximates market.
                      Other assets and securities for which market quotations
                      are not readily available or which are restricted as to
                      sale are valued by such methods as the Board of Directors
                      deems in good faith to reflect fair value. Securities may
                      be valued on the basis of prices provided by a pricing
                      service when such prices are believed to reflect the fair
                      market value of such securities. The prices provided by a
                      pricing service may be determined without regard to bid or
                      last sale prices of each security but take into account
                      institutional-size transactions in similar groups of
                      securities as well as any developments related to specific
                      securities.
 
                      The Fund's share price can be found daily in the mutual
                      fund listings of most major newspapers under the heading

                      Incorporation permit the Directors to issue 2,200,000,000
                      shares of common stock, with a one cent par value. The
                      Board of Directors has the power to designate one or more
                      classes ("series") of shares of common stock and to
                      classify or reclassify any unissued shares with respect to
                      such series. Currently the Company is offering shares of
                      two series.

                      exchange, dividends, retirement or other features; and
                      have no pre-emptive rights. Such shares have
                      non-cumulative voting rights, meaning that the holders of

                      required by the Investment Company Act of 1940 and other
                      applicable law. An annual meeting will be held to vote on
                      the removal of a Director or Directors of the Company if
                      requested in writing by the holders of not less than 10%
                      of the outstanding shares of the Company.
 
                      All securities and cash are held by State Street Bank and

PURCHASE              1) Because of the risks associated with common stock

                         the right to reject any specific purchase (or exchange
                         purchase) request. The Fund also reserves the right to
                         suspend the offering of shares for a period of time.
 
                      2) Vanguard will not accept third-party checks to purchase

                      capital gains distributions in another Vanguard Fund

TAX CAUTION

INVESTORS SHOULD ASK
ABOUT THE TIMING OF
CAPITAL GAINS AND
DIVIDEND DISTRIBUTIONS
BEFORE INVESTING
                      Under federal tax laws, the Fund is required to distribute
                      net capital gains and dividend income to Fund
                      shareholders. These distributions are made to all
                      shareholders who own Fund shares as of the distribution's
                      record date, regardless of how long the shares have been
                      owned. Purchasing shares just prior to the record date
                      could have a significant impact on your tax liability for
                      the year. For example, if you purchase shares immediately
                      prior to the record date of a sizable capital gain or
                      income dividend distribution, you will be assessed taxes
                      on the amount of the capital gain and/or dividend
                      distribution later paid even though you owned the Fund
                      shares for just a short period of time. (Taxes are due on
                      the distributions even if the dividend or gain is
                      reinvested in additional Fund shares.) While the total
                      value of your investment will be the same after the
                      distribution -- the amount of the distribution will offset
                      the drop in the net asset value of the shares -- you
                      should be aware of the tax implications the timing of your
                      purchase may have.
 
                      Prospective investors should, therefore, inquire about
                      potential distributions before investing. The Fund's
                      annual capital gains distribution normally occurs in
                      December, while income dividends are generally paid
                      semi-annually in June and December. For additional
                      information on distributions and taxes, see the section
                      titled "Dividends, Capital Gains, and Taxes."

                      other guarantors that Vanguard deems acceptable. A
                      SIGNATURE GUARANTEE CANNOT BE PROVIDED BY A NOTARY PUBLIC.
 
CERTIFICATES
                      Share certificates will be issued upon request. If a
                      certificate is lost, you may incur an expense to replace
                      it.
 
BROKER-DEALER
PURCHASES             If you purchase shares in Vanguard funds through a
                      registered broker-dealer or investment adviser, the
                      broker-dealer or adviser may charge a service fee.
 
CANCELLING TRADES     The Fund will not cancel any trade (e.g., a purchase,
                      exchange or redemption) believed to be authentic, received
                      in writing or by telephone, once the trade request has
                      been received.

WHEN YOUR
ACCOUNT WILL
BE CREDITED           Your trade date is the date on which your account is
                      credited. If your purchase is made by check, Federal Funds
                      wire, or exchange, and is received by the close of the New
                      York Stock Exchange (generally 4:00 p.m. Eastern time),
                      your trade date is the day of receipt. If your purchase is
                      received after the close of the Exchange, your trade date
                      is the next business day. Your shares are purchased at the
                      net asset value determined on your trade date.
 
                      In order to prevent lengthy processing delays caused by
                      the clearing of foreign checks, Vanguard will only accept
                      a foreign check which has been drawn in U.S. dollars and
                      has been issued by a foreign bank with a U.S.
                      correspondent bank. The name of the U.S. correspondent
                      bank must be printed on the face of the foreign check.

IMPORTANT REDEMPTION
INFORMATION           Shares purchased by check or Fund Express may be redeemed
                      at any time. However, your redemption proceeds will not be
                      paid until payment for the purchase is collected, which
                      may take up to ten calendar days.
    
- --------------------------------------------------------------------------------
 
DELIVERY OF
REDEMPTION PROCEEDS   Redemption requests received by telephone prior to the
                      close of the New York Stock Exchange are processed on the
                      day of receipt and the redemption proceeds are normally
                      sent on the following business day.
 
                      Redemption requests received by telephone after the close
                      of the Exchange (generally 4:00 p.m., Eastern time) are
                      processed on the business day following receipt and the
                      proceeds are normally sent on the second business day
                      following receipt.
 
                      Redemption proceeds must be sent to you within seven days
                      of receipt of your request in Good Order, except as
                      described above in Important Redemption Information.

                      If you experience difficulty in making a telephone
                      redemption during periods of drastic economic or market
                      changes, your redemption request may be made by regular or
                      express mail. It will be implemented at the net asset
                      value next determined after your request has been received
                      by Vanguard in Good Order. The Fund reserves the right to
                      revise or terminate the telephone redemption privilege at
                      any time.
 
                      The Fund may suspend the redemption right 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 the Board of Directors determines that it would be
                      detrimental to the best interests of the Fund's remaining
                      shareholders to make payment in cash, the Fund may pay
                      redemption proceeds in whole or in part by a distribution
                      in kind of readily marketable securities.
- --------------------------------------------------------------------------------
 
VANGUARD'S AVERAGE
COST STATEMENT        If you make a redemption from a qualifying account,
                      Vanguard will send you an Average Cost Statement which
                      provides you with the tax basis of the shares you
                      redeemed. Please see "Statements and Reports" for
                      additional information.
- --------------------------------------------------------------------------------
 
LOW BALANCE
FEE AND
MINIMUM ACCOUNT
BALANCE
REQUIREMENT           Due to the relatively high cost of maintaining smaller
                      accounts, the Fund will automatically deduct a $10 annual
                      fee from non-retirement accounts with balances falling
                      below $2,500 ($1,000 for Uniform Gifts/Transfers to Minors
                      Act accounts). This fee deduction will occur mid-year,
                      beginning in 1996. The fee generally will be waived for
                      investors whose aggregate Vanguard assets exceed $50,000.
 
                      In addition, the Fund reserves the right to liquidate any
                      non-retirement account that is below the minimum initial
                      investment amount of $3,000. If at any time your total
                      investment does not have a value of at least $3,000, you
                      may be notified that your account is below the Fund's
                      minimum account balance requirement. You would then be
                      allowed 60 days to make an additional investment before
                      the account is liquidated. Proceeds would be promptly paid
                      to the registered shareholder.
 
                      Vanguard will not liquidate your account if it has fallen
                      below $3,000 solely as a result of declining markets
                      (i.e., a decline in a Fund's net asset value).

EXCHANGING YOUR
SHARES                Should your investment goals change, you may exchange your
                      shares of Vanguard/ Windsor II for those of other
                      available Vanguard Funds.

IMPORTANT EXCHANGE
INFORMATION           Before you make an exchange, you should consider the
                      following:
 
                      - Please read the Fund's prospectus before making an
                        exchange. For a copy and for answers to any questions
                        you may have, call our Investor Information Department
                        (1-800-662-7447).
 
                      - An exchange is treated as a redemption and a purchase;
                        therefore, you could realize a taxable gain or loss on
                        the transaction.
 
                      - Exchanges are accepted only if the registrations and the
                        Taxpayer Identification numbers of the two accounts are
                        identical.
 
                      - The shares to be exchanged must be on deposit and not
                        held in certificate form.
 
                      - New accounts are not currently accepted in
                        Vanguard/Windsor Fund or Vanguard PRIMECAP Fund.
 
                      - The redemption price of shares redeemed by exchange is
                        the net asset value next determined after Vanguard has
                        received any required documents in Good Order.
 
                      - When opening a new account by exchange, you must meet
                        the minimum investment requirement of the new Fund.
 
                      Every effort will be made to maintain the exchange
                      privilege. However, the Fund reserves the right to revise
                      or terminate its provisions, or to limit the amount of or
                      reject any exchange, as deemed necessary, at any time.
 
                      The Fund's exchange purchase privilege is available only
                      in states in which the shares of the Fund are registered
                      for sale. The Fund's shares are currently registered for
                      sale in all 50 states and the Fund intends to maintain
                      such registration.
- --------------------------------------------------------------------------------
 
EXCHANGE
PRIVILEGE
LIMITATIONS           The Fund's exchange privilege is not intended to afford
                      shareholders a way to speculate on short-term movements in
                      the market. Accordingly, in order to prevent excessive use
                      of the exchange privilege that may potentially disrupt the
                      management of the Fund and increase transaction costs, the
                      Fund has established a policy of limiting excessive
                      exchange activity.

<PAGE>   70
 
                      Exchange activity generally will not be deemed excessive
                      if limited to TWO SUBSTANTIVE EXCHANGE REDEMPTIONS (AT
                      LEAST 30 DAYS APART) from the Fund during any twelve month
                      period. Notwithstanding these limitations, the Fund
                      reserves the right to reject any purchase request
                      (including exchange purchases from other Vanguard
                      portfolios) that is reasonably deemed to be disruptive to
                      efficient portfolio management.

IMPORTANT
INFORMATION
ABOUT TELEPHONE
TRANSACTIONS          The ability to initiate redemptions (except wire
                      redemptions) and exchanges by telephone is automatically
                      established on your account unless you request in writing
                      that telephone transactions on your account not be
                      permitted.
 
                      To protect your account from losses resulting from
                      unauthorized or fraudulent telephone instructions,
                      Vanguard adheres to the following security procedures:
 
                      1. SECURITY CHECK.  To request a transaction by telephone,

                      The purpose of this table is to assist you in
                      understanding the various costs and expenses that an
                      investor would bear directly or indirectly as a
                      shareholder in the Fund.
 
                      The following example illustrates the expenses that you
                      would incur on a $1,000 investment over various periods,
                      assuming (1) a 5% annual rate of return and (2) redemption
                      at the end of each period. As noted in the table above,
                      the Fund charges no redemption fees of any kind.

YIELD AND
TOTAL RETURN          From time to time the Fund may advertise its yield and
                      total return. Both yield and total return figures are
                      based on historical earnings and are not intended to
                      indicate future performance. The "total return" of the
                      Fund refers to the average annual compounded rates of
                      return over one- , five- and ten-year periods or for the
                      life of the Fund (as stated in the advertisement) that
                      would equate an initial amount invested at the beginning
                      of a stated period to the ending redeemable value of the
                      investment, assuming the reinvestment of all dividend and
                      capital gains distributions.
 
                      In accordance with the industry guidelines set forth by
                      the U.S. Securities and Exchange Commission, the "30-day
                      yield" of the Fund is calculated daily by dividing the net
                      investment income per share earned during a 30-day period
                      by the net asset value per share on the last day of the
                      period. Net investment income includes interest and
                      dividend income earned on the Fund's securities, and is
                      net of all expenses and all recurring and nonrecurring
                      charges that have been applied to all shareholder
                      accounts. The yield calculation assumes that the net
                      investment income earned over thirty days is compounded
                      monthly for six months and then annualized. Methods used
                      to calculate advertised yields are standardized for all
                      stock and bond mutual funds. However, these methods differ
                      from the accounting methods used by the Fund to maintain
                      its books and records, and so the advertised 30-day yield
                      may not fully reflect the income paid to an investor's
                      account or the yield reported in the Fund's reports to
                      shareholders. Additionally, the Fund may

INVESTMENT
OBJECTIVES
THE FUND SEEKS TO
PROVIDE LONG-TERM
GROWTH OF CAPITAL
AND INCOME            The objective of the Fund is to provide long-term growth
                      of capital and income. The Fund's secondary objective is
                      to provide current income. There can be no assurance that
                      the Fund will achieve these objectives.
 
                      These investment objectives are fundamental and so cannot
                      be changed without the approval of a majority of the
                      Fund's shareholders.

INVESTMENT
POLICIES
THE FUND INVESTS
PRIMARILY IN
COMMON STOCKS         The Fund follows a flexible investment strategy,
                      emphasizing income-producing stocks which the investment
                      advisers believe to be undervalued by the market at the
                      time of purchase. Generally, these securities are
                      characterized by below-average price-earnings ratios
                      relative to the stock market, as measured by the Standard
                      & Poor's 500 Composite Stock Price Index. The Fund is
                      managed without regard to tax ramifications.
 
                      Stocks will be selected based upon assessments of
                      statistical measures of current value (such as low
                      price-earnings and low price-to-book value ratios) and
                      future earnings prospects. Returns on such stocks can be
                      influenced by the recognition of their undervaluation by
                      other investors based on statistical measures or changes
                      in expectations regarding potential earnings and dividend
                      growth. If a stock has reached a fully-valued position as
                      determined by one of the Fund's investment advisers, the
                      stock will ordinarily be sold regardless of the time it
                      has been held and replaced by one or more securities that
                      are considered to be undervalued.
 
                      Although the Fund invests primarily in common stocks, it
                      may invest in money market instruments, fixed-income
                      securities, and other equity securities, such as preferred
                      stock. The Fund is expected, under normal circumstances,
                      to be substantially fully invested in common stocks. In
                      addition, the Fund may invest in stock futures and options
                      to a limited extent. See "Implementation of Policies" for
                      a description of these and other investment practices of
                      the Fund.
 
                      The Fund is responsible for voting the shares of all
                      securities it holds.
 
                      The investment policies of the Fund are not fundamental
                      and so may be changed by the Board of Directors without
                      shareholder approval.

INVESTMENT RISKS
THE FUND IS SUBJECT
TO MARKET RISK
                      As a mutual fund investing primarily in common stocks, the
                      Fund is subject to MARKET RISK -- i.e., the possibility
                      that common stock prices will decline over short or even
                      extended periods. The U.S. stock market has tended to be
                      cyclical, with periods when stock prices generally rise
                      and periods when prices generally decline.
 
                      To illustrate the volatility of domestic stock prices, the
                      following table sets forth the extremes for U.S. stock
                      market returns as well as the average return for the
                      period

</TABLE>
 
                      As shown, common stocks have provided annual total returns
                      (capital appreciation plus dividend income) averaging
                      +10.7% for all 10-year periods from 1926 to 1995. While
                      this average return can be used as a guide for setting
                      reasonable expectations for future stock market returns,
                      it may not be useful for forecasting future returns in any
                      particular period, as stock returns are quite volatile
                      from year to year.
 
                      This table of U.S. stock market returns should not be
                      viewed as a representation of future returns for the Fund
                      or the U.S. stock market. The illustrated returns
                      represent historical investment performance, which may be
                      a poor guide to future returns. Also, stock market indexes
                      such as the S&P 500 are based on unmanaged portfolios of
                      securities before transaction costs and other expenses.
                      Such costs will reduce the relative investment performance
                      of the Fund and other "real world" portfolios. Finally,
                      the Fund is likely to differ in portfolio composition from
                      broad stock market averages, and so the Fund's performance
                      should not be expected to mirror the returns provided by a
                      specific index.
 
THE FUND IS ALSO
SUBJECT TO
MANAGER RISK          The investment adviser manages the Fund according to the
                      traditional methods of "active" investment management,
                      which involve the buying and selling of securities based
                      upon economic, financial and market analysis and
                      investment judgment. MANAGER RISK refers to the
                      possibility that the Fund's investment adviser may fail to
                      execute the Fund's investment strategy effectively. As a
                      result, the Fund may fail to achieve its stated objective.

WHO SHOULD
INVEST
LONG-TERM INVESTORS
SEEKING GROWTH OF
CAPITAL AND INCOME    The Fund is intended for investors who are seeking growth
                      of capital and income. Although the Fund's secondary
                      objective is to provide current income, investors should
                      not consider the Fund a substitute for fixed-income
                      investments. The Fund is intended to be a long-term
                      investment vehicle and is not designed to provide
                      investors with a means of speculating on short-term stock
                      market movements. Investors who engage in excessive
                      account activity generate additional costs which are borne
                      by all of the Fund's shareholders. In order to minimize
                      such costs, the Fund has adopted certain policies. The
                      Fund reserves the right to reject any purchase request
                      (including exchange purchases from other Vanguard
                      portfolios) that is reasonably deemed to be disruptive to
                      efficient portfolio management, either because of the
                      timing of the investment or previous excessive trading by
                      the investor. Additionally, the Fund reserves the right to
                      suspend the offering of its shares.

                      No assurance can be given that the Fund will attain its
                      objectives or that shareholders will be protected from the
                      risk of loss that is inherent in equity investing.
                      Investors may wish to reduce the potential risk of
                      investing in the Fund by purchasing shares on a regular
                      periodic basis (dollar-cost averaging) rather than making
                      an investment in one lump sum.
 
                      Investors should not consider the Fund a complete
                      investment program. Most investors should maintain
                      diversified holdings of securities with different risk
                      characteristics -- including common stocks, bonds and
                      money market instruments. Investors may also wish to
                      complement an investment in the Fund with other types of
                      common stock investments.
- --------------------------------------------------------------------------------
 
IMPLEMENTATION
OF POLICIES           In addition to investing primarily in equity securities,
                      the Fund follows a number of additional investment
                      practices to achieve its objectives.
 
THE FUND MAY INVEST
IN SHORT-TERM FIXED
INCOME SECURITIES     Although it normally seeks to remain substantially fully
                      invested in equity securities, the Fund may invest
                      temporarily in certain short-term fixed income securities.
                      Such securities may be used to invest uncommitted cash
                      balances, to maintain liquidity to meet shareholder
                      redemptions, or to take a temporarily defensive position
                      against a potential stock market decline. No more than 35%
                      of the Fund's assets will be committed to short-term fixed
                      income securities for purposes other than taking a
                      temporary defensive position. These securities include:
                      obligations of the U.S. Government and its agencies or
                      instrumentalities; commercial paper, bank certificates of
                      deposit, and bankers' acceptances; and repurchase
                      agreements collateralized by these securities.
 
                      A repurchase agreement is a means of investing monies for
                      a short period. In a repurchase agreement, a seller -- a
                      U.S. commercial bank or recognized U.S. securities
                      dealer -- sells securities to the Fund and agrees to
                      repurchase the securities at the Fund's cost plus interest
                      within a specified period (normally one day). In these
                      transactions, the securities purchased by the Fund will
                      have a total value equal to or in excess of the value of
                      the repurchase agreement, and will be held by the Fund's
                      Custodian Bank until repurchased.
 
THE FUND MAY LEND
ITS SECURITIES        The Fund may lend its investment securities to qualified
                      institutional investors for either short-term or long-term
                      periods for the purpose of realizing additional income.
                      Loans of securities by the Fund will be collateralized by
                      cash, letters of credit, or securities issued or
                      guaranteed by the U.S. government or its agencies. The
                      collateral will equal at least 100% of the current market
                      value of the loaned securities.
 
   
BORROWING             The Fund may borrow money, subject to the restrictions
                      described on page 8 in Investment Limitations, for
                      temporary or emergency purposes, including the meeting of
                      redemption requests which might otherwise require the
                      untimely disposition of securities.
    
 
PORTFOLIO TURNOVER
IS NOT EXPECTED TO
EXCEED 100%           Although it generally seeks to invest for the long term,
                      the Fund retains the right to sell securities irrespective
                      of how long they have been held. It is anticipated that
                      the annual portfolio turnover of the Fund will not exceed
                      100%. A turnover rate of 100%
 
                                        6
<PAGE>   81
 
                      would occur, for example, if all of the securities of the
                      Fund were replaced within one year.
 
DERIVATIVE
INVESTING             Derivatives are instruments whose values are linked to or
                      derived from an underlying security or index. The most
                      common and conventional types of derivative securities are
                      futures and options.
 
THE FUND MAY INVEST
IN DERIVATIVE
SECURITIES            The Fund may invest in futures contracts and options, but
                      only to a limited extent. Specifically, the Fund may enter
                      into futures contracts provided that not more than 5% of
                      its assets are required as a futures contract deposit; in
                      addition, the Fund may enter into futures contracts and
                      options transactions only to the extent that obligations
                      under such contracts or transactions represent not more
                      than 20% of the Fund's assets.
 
                      Futures contracts and options may be used for several
                      common fund management strategies: to maintain cash
                      reserves while simulating full investment, to facilitate
                      trading, to reduce transaction costs, or to seek higher
                      investment returns when a specific futures contract is
                      priced more attractively than other futures contracts or
                      the underlying security or index. While futures contracts
                      and options can be used as leveraged investments, the Fund
                      may not use futures or options transactions to leverage
                      its net assets.
 
                      For example, in order to remain fully invested in stocks
                      while maintaining liquidity to meet potential shareholder
                      redemptions, the Fund may invest a portion of its assets
                      in a stock futures contract. Because futures contracts
                      only require a small initial margin deposit, the Fund
                      would then be able to maintain a cash reserve for
                      potential redemptions, while at the same time remaining
                      fully invested. Also, because the transaction costs of
                      futures and options may be lower than the costs of
                      investing in stocks directly, it is expected that the use
                      of futures contracts and options may reduce the Fund's
                      total transaction costs.
 
                      The Fund may use futures contracts for bona fide "hedging"
                      purposes. In executing a hedge, a manager sells, for
                      example, stock index futures to protect against a decline
                      in the stock market. As such, if the market drops, the
                      value of the futures position will rise, thereby
                      offsetting the decline in value of the Fund's stock
                      holdings.
 
FUTURES CONTRACTS
AND OPTIONS POSE
CERTAIN RISKS         The primary risks associated with the use of futures
                      contracts and options are: (i) imperfect correlation
                      between the change in market value of the stocks held by
                      the Fund and the prices of futures contracts and options;
                      and (ii) possible lack of a liquid secondary market for a
                      futures contract and the resulting inability to close a
                      futures position prior to its maturity date. The risk of
                      imperfect correlation will be minimized by investing in
                      those contracts whose price fluctuations are expected to
                      resemble those of the Fund's underlying securities. The
                      risk that the Fund will be unable to close out a futures
                      position will be minimized by entering into such
                      transactions on a national exchange with an active and
                      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
 
                                        7
<PAGE>   82
                      in a futures contract may result in immediate and
                      substantial loss (or gain) to the investor. When investing
                      in futures contracts, the Fund will segregate cash or cash
                      equivalents in the amount of the underlying obligation.

LIMITATIONS

THE FUND HAS ADOPTED  The Fund has adopted certain limitations on its investment
CERTAIN FUNDAMENTAL   practices. Specifically, the Fund will not:               
LIMITATIONS           
                      (a)  with respect to 75% of the value of its 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 total
                           assets of the Fund would be invested in the
                           securities of such issuer;
 
                      (b)  invest more than 25% of its assets in any one
                           industry; and
 
                      (c)  borrow money, except that the Fund may borrow from
                           banks (or through reverse repurchase agreements), for
                           temporary or emergency (not leveraging) purposes,
                           including the meeting of redemption requests which
                           might otherwise require the untimely disposition of
                           securities, in an amount not exceeding 10% of the
                           value of the net assets of the Fund (including the
                           amount borrowed and the value of any outstanding
                           reverse repurchase agreements) at the time the
                           borrowing is made. Whenever borrowings exceed 5% of
                           the value of the net assets of the Fund, the Fund
                           will not make any additional investments.
 
                      These investment limitations are considered at the time
                      investment securities are purchased. The investment
                      limitations described here and in the Statement of
                      Additional Information are fundamental and may be changed
                      only with the approval of a majority of the Fund's
                      shareholders.

MANAGEMENT OF
THE FUND

VANGUARD ADMINISTERS  The Fund is a member of The Vanguard Group of Investment  
AND DISTRIBUTES       Companies, a family of more than 30 investment companies  
THE FUND              with more than 90 distinct investment portfolios and total
                      assets in excess of $180 billion. 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 certain Vanguard funds, including
                      Vanguard/Windsor II. As a result of Vanguard's unique
                      corporate structure, the Vanguard funds have costs
                      substantially lower than those of most competing mutual
                      funds. In 1995, the average expense ratio (annual costs
                      including advisory fees divided by total net assets) for
                      the Vanguard funds amounted to approximately .31% compared
                      to an average of 1.11% for the mutual fund industry (data
                      provided by Lipper Analytical Services).
 
                      The Officers of the Fund manage its day-to-day operations
                      and are responsible to the Fund's Board of Directors. The
                      Directors set broad policies for the Fund and choose its
                      Officers. A list of the Directors and Officers of the Fund
                      and a statement of their present positions and principal
                      occupations during the past five years can be found in the
                      Statement of Additional Information.

                      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 net 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.
 
                      Vanguard provides distribution and marketing services to
                      the funds. The funds are available on a no-load basis
                      (i.e., there are no sales commissions or 12b-1 fees).
                      However, each fund bears its share of the Group's
                      distribution costs.

ADVISERS
FOUR ADVISERS
OVERSEE THE FUND'S
INVESTMENTS:          Vanguard/Windsor II employs a multi-manager approach
                      utilizing four investment advisers to manage the Fund's
                      assets. The Fund has investment advisory contracts with:
                      Barrow, Hanley, Mewhinney & Strauss, Inc. ("BHM&S"), One
                      McKinney Plaza, 3232 McKinney Avenue, 15th Floor, Dallas,
                      TX 75204-2429; Equinox Capital Management, Inc.
                      ("Equinox"), 399 Park Ave., 28th floor, New York, NY
                      10022; and Tukman Capital Management, Inc. ("Tukman"), 60
                      East Sir Francis Drake Boulevard, Larkspur, CA 94939.
                      Additionally, a portion of the Fund's assets will be
                      managed on an at cost basis by Vanguard's Core Management
                      Group. Neither BHM&S, Equinox nor Tukman is affiliated in
                      any way with Wellington Management Company, the investment
                      adviser to Vanguard/Windsor Fund.
 
                      The proportion of the net assets of the Fund managed by
                      each adviser is established by the Board of Directors and
                      may be changed in the future as circumstances warrant.

                      and quality of brokerage services available are considered
                      in making these determinations.
 
                      The Fund has authorized BHM&S, Equinox, Tukman and
                      Vanguard's Core Management Group to pay higher commissions
                      in recognition of brokerage services deemed necessary for
                      the achievement of better execution, provided the advisers
                      believe this to be in the best interest of the Fund.
                      Although the Fund does not market its shares

                      through intermediary brokers or dealers, the Fund may
                      place orders with qualified broker-dealers who recommend
                      the Fund to clients if the Officers of the Fund believe
                      that the quality of the transaction and the commission are
                      comparable to what they would be with other qualified
                      brokerage firms.
 
                      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; and (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 of the Fund, which shall include
                      substantially the information concerning the adviser that
                      would have normally been included in a proxy statement.

PERFORMANCE
RECORD                The table below provides investment results for the Fund
                      for several periods throughout the Fund's lifetime. The
                      results shown represent "total return" investment
                      performance which assumes the reinvestment of all capital
                      gains and income dividends, annualized for the indicated
                      periods. Also included is comparative information with
                      respect to the unmanaged Standard & Poor's 500 Composite
                      Stock Price Index, a widely-used barometer of stock market
                      activity, and the Consumer Price Index, a statistical
                      measure of changes in the prices of goods and services.
                      The table does not make any allowance for federal, state
                      or local income taxes which shareholders must pay on a
                      current basis.
 
                      The results should not be considered a representation of
                      the total return from an investment made in the Fund
                      today. This information is provided to help investors
                      better understand the Fund and may not provide a basis for
                      comparison with other investments or mutual funds which
                      use a different method to calculate performance.

DIVIDENDS, CAPITAL
GAINS AND TAXES
THE FUND PAYS
SEMI-ANNUAL
DIVIDENDS AND
ANY CAPITAL GAINS
ANNUALLY              The Fund expects to pay dividends from ordinary income
                      semi-annually. Capital gains distributions, if any, will
                      be made annually. All dividend and capital gains
                      distributions are automatically reinvested in additional
                      shares of the Fund. In order to satisfy certain
                      distribution requirements of the IRS, the Fund may also
                      declare special year-end distributions during December.
                      The Fund intends to continue to qualify as a "regulated
                      investment company" under the Internal Revenue Code so
                      that it will not be subject to federal income tax to the
                      extent that its income is distributed to its shareholders.
 
                      If you utilize the Fund as an investment option in an
                      employer-sponsored retirement savings plan, dividend and
                      capital gains distributions from the Fund generally will
                      not be subject to current taxation, but will accumulate on
                      a tax-deferred basis. In general, employer-sponsored
                      retirement and savings plans are governed by a complex set
                      of tax rules. You should consult your plan administrator,
                      the plan's "Summary Plan Description," or a professional
                      tax adviser regarding the tax consequences of your
                      participation in the plan and of any plan contributions or
                      withdrawals.

THE SHARE PRICE
OF THE FUND           The Fund's share price or "net asset value" per share is
                      determined by dividing the total market value of the
                      Fund's investments and other assets, less any liabilities,
                      by the number of outstanding shares of the Fund. Net asset
                      value in determined as of the regular close of the New
                      York Stock Exchange (generally 4:00 p.m. Eastern time) on
                      each day the exchange is open for trading.
 
                      Portfolio securities that are listed on a securities
                      exchange are valued at the latest quoted sales prices.
                      Price information on listed securities is taken from the
                      exchange where the security is primarily traded.
                      Securities which are listed on an exchange and which are
                      not traded on the valuation date are valued at the mean of
                      the latest quoted bid and asked prices. Unlisted
                      securities for which market quotations are readily
                      available are valued at the latest quoted bid price.
                      Short-term instruments (those with remaining maturities of
                      60 days or less) are valued at cost, plus or minus any
                      amortized discount or premium, which approximates market.
                      Other assets and securities for which market quotations
                      are not readily available or which are restricted as to
                      sale are valued by such methods as the Board of Directors
                      deems in good faith to reflect fair value. Securities may
                      be valued on the basis of prices provided by a pricing
                      service when such prices are believed to reflect the fair
                      market value of such securities. The prices provided by a
                      pricing service may be determined without regard to bid or
                      last sale prices of each security but take into account
                      institutional-size transactions in similar groups of
                      securities as well as any developments related to specific
                      securities.
 
                      The Fund's share price can be found daily in the mutual
                      fund listings of most major newspapers under the heading
                      of Vanguard.

GENERAL
INFORMATION           The Company is a Maryland corporation. The Articles of
                      Incorporation permit the Directors to issue 2,200,000,000
                      shares of common stock, with a one cent par value. The
                      Board of Directors has the power to designate one or more
                      classes ("series") of shares of common stock and to
                      classify or reclassify any unissued shares with respect to
                      such series. Currently the Company is offering shares of
                      two series.
 
                      The shares of each series of the Company are fully paid
                      and non-assessable; have no preference as to conversion,
                      exchange, dividends, retirement or other features, and
                      have no pre-emptive rights. Such shares have
                      non-cumulative voting rights, meaning that the holders of
                      more than 50% of the shares voting for the election of
                      Directors can elect 100% of the Directors if they so
                      choose.

                      required by the Investment Company Act of 1940 and other
                      applicable law. An annual meeting will be held to vote on
                      the removal of a Director or Directors of the Company if
                      requested in writing, by the holders of not less than 10%
                      of the outstanding shares of the Company.
 
                      All securities and cash are held by State Street Bank and
                      Trust Company, Boston, MA. The Vanguard Group, Inc.,

                                  THE COMPANY
 
     Vanguard/Windsor Funds, Inc. (the "Company") is an open-end, diversified,
management investment company whose shares are currently offered in two separate
series -- the Vanguard/Windsor Fund series and the Vanguard/Windsor II series.
Each series in effect represents a separate mutual fund. Vanguard/Windsor Fund
series has been offered under the name "Windsor Fund" since 1958. Shares of
Vanguard/Windsor II were initially offered on June 24, 1985. Wellington
Management Company has served as investment adviser to the Vanguard/Windsor Fund
series since its inception. Barrow, Hanley, Mewhinney & Strauss, Inc. ("BHM&S"),
Equinox Capital Management, Inc. ("Equinox"); and Tukman Capital Management,
Inc. ("Tukman"), three separate and distinct investment counseling firms that
have no affiliation with Wellington Management Company, nor with each other,
serve as investment advisers to the Vanguard/Windsor II series. Additionally,
The Vanguard Group, Inc., ("Vanguard") provides investment advisory services on
an at-cost basis with respect to a portion of Vanguard/Windsor II's assets.
 
                       INVESTMENT OBJECTIVES AND POLICIES
 
     The following policies supplement the investment objectives and policies
set forth in each of the Company's Prospectuses.
 
     PORTFOLIO TURNOVER.  While the rate of portfolio turnover is not a limiting
factor when the investment adviser deems changes appropriate, it is anticipated
that the annual portfolio turnover rate for each series will not normally exceed
100%. A rate of turnover of 100% could occur, for example, if all of the
securities in a series' portfolio are replaced within a period of one year. The
portfolio turnover rates for the Vanguard/ Windsor Fund series and the
Vanguard/Windsor II series are set forth under "Financial Highlights," in
Vanguard/Windsor Fund's and Vanguard/Windsor II's Prospectuses, respectively.

     REPURCHASE AGREEMENTS.  Each series may invest in repurchase agreements
with domestic banks, brokers or dealers, either for temporary defensive purposes
due to market conditions, or to generate income from its excess cash balances. A
repurchase agreement is an agreement under which the series acquires a money
market instrument (generally security issued by the U.S. Government or an agency
thereof, a banker's acceptance or a certificate of deposit) from a domestic
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
series and is unrelated to the interest rate on the underlying instrument. In
these transactions, the securities acquired by the series (including accrued
interest earned thereon) must have a total value in excess of the value of the
repurchase agreement and are held by the Company's custodian bank until
repurchased. In addition, the Board of Directors will monitor the repurchase
agreement transactions for each series 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 Company. No
more than an aggregate of 15% of a series assets, at the time of investment,
will be invested in repurchase agreements having maturities longer than seven
days and in securities subject to legal or contractual restrictions on resale
for which there are no readily available market quotations. See "Illiquid
Securities" on page B-3.
 
     The use of repurchase agreements involves certain risks. For example, if
the seller of the securities under an agreement defaults on its obligation to
repurchase the underlying securities at a time when the value of these
securities has declined, the series may incur a loss upon disposition of them.
If the seller becomes insolvent and subject to liquidation or reorganization
under bankruptcy or other laws, a bankruptcy court may determine that the
underlying securities are collateral for a loan by the series not within the
control of the series and therefore subject to sale by the trustee in
bankruptcy. Finally, it is possible that the series may not be able to
substantiate its interest in the underlying securities. While the Company's
management acknowledges these risks, it is expected that they can be controlled
through careful monitoring procedures.
 
     LENDING OF SECURITIES.  Each series 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, each series 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 series. Each series may lend its portfolio securities to
qualified brokers, dealers, domestic banks or other domestic financial
institutions, so long as the terms, and the structure of such loans are not
inconsistent 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 series collateral consisting of cash, an irrevocable
letter of credit or securities issued or guaranteed by a domestic bank or 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
series at any time and (d) the series receive reasonable interest on the loan
(which many include the series' investing any cash collateral in interest
bearing short-term investments), any distributions on the loaned securities and
any increase in their market value. A series will not lend portfolio securities
if, as a result, the aggregate of such loans exceeds 33 1/3% of the value of the
series' total assets. Loan arrangements made will comply with all other
applicable regulatory requirements, including the rules of the New York Stock
Exchange, which rules 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 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 (Trustees). In addition, voting
rights pass with
 
                                       B-2
<PAGE>   97
 
the loaned securities, but if a material event occurs affecting an investment on
loan, the loan must be called and the securities voted.
 
     FOREIGN INVESTMENTS.  As indicated in the Prospectus, the Fund may include
foreign securities to a certain extent. 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 Portfolios' foreign securities will be somewhat greater than
the expenses for the custodian 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.
 
     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.
 
     FUTURES CONTRACTS.  Each series may enter into stock futures contracts,
options, and options on futures contracts only for the purpose of remaining
fully invested 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.
 
     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," "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.
 
                                       B-3
<PAGE>   98
 
     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 on margin that
may range upward from less than 5% of the value of the contract being traded.
 
     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 for as long as the contract remains open. Each series
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 markets 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
interest rates. Each series intends to use futures contracts only for bona fide
hedging purposes.
 
     Regulations of the CFTC applicable to the Company require that all of its
futures transactions constitute bona fide hedging transactions. Each series 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, a series 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 series upon sale of open futures contracts.
 
     Although techniques other than the sale and purchase of futures contracts
could be used to control the exposure of the series' income to market
fluctuations, the use of futures contracts may be a more effective means of
hedging this exposure. While each series 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 portfolio securities.
 
     RESTRICTIONS ON THE USE OF FUTURES CONTRACTS.  A series 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 series' total assets. In addition, a series will not enter into
futures contracts to the extent that its outstanding obligations to purchase
securities under these contracts would exceed 20% of the series' total assets.
Assets committed to futures contracts or options will be held in a segregated
account at the Fund's custodian bank.
 
     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, a series would continue to be required to make daily cash payments to
maintain its required margin. In such situations, if a series 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, a series may be
required to make delivery of the instruments underlying interest rate futures
contracts it holds. The inability to close options and futures positions also
could have an adverse impact on the ability to effectively hedge its portfolio.
A series 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.
 
                                       B-4
<PAGE>   99
 
     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 Portfolio are engaged in only for hedging purposes, the
Adviser does not believe that the series is subject to the risks of loss
frequently associated with futures transactions. The series would presumably
have sustained comparable losses if, instead of the futures contract, it had
invested in the underlying security and sold it after the decline.
 
     Utilization of futures transactions by the series 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 a series could both lose money on futures contracts and also
experience a decline in value of its portfolio securities. There is also the
risk of loss by a series of margin deposits in the event of bankruptcy of a
broker with whom the series has an open position in a futures contract or
related option. Additionally, investments in futures and options involve the
risk that the investment adviser will incorrectly predict stock market and
interest rate trends.
 
     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.  Each series is required for
Federal income tax purposes to recognize as income for each taxable year its net
unrealized gains and losses on 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
a series may affect the holding period of such securities and, consequently, the
nature of the gain or loss on such securities upon disposition. The series 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 series.
 
     In order for a series 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, and gains from the sale of
securities or foreign currencies, or other income derived from the fund's
business of investing in securities or currencies. 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 series annual gross income. It is
anticipated that any net gain realized from the closing 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 series 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 series' fiscal year and which are recognized for tax purposes,
will not be considered gains on securities held less than three months for the
purpose of the 30% test.
 
                                       B-5
<PAGE>   100
 
     The series 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 series' fiscal year on futures transactions). Such
distributions will be combined with distributions of capital gains realized on
the series' other investments and shareholders will be advised on the nature of
the payments.
 
                               PURCHASE OF SHARES
 
     The purchase price of shares of each series of the Company is the net asset
value next determined after the order is received in Good Order, as defined in
the Prospectus. 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.
 
     Each series 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 series, 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 series' shares.
 
                              REDEMPTION OF SHARES
 
     Each series 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 series to dispose of securities owned by it,
or to determine fairly the value of its assets; and (iii) for such other periods
as the Commission may permit.
 
     The Company 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 a series 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 readily marketable 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 interests of the
Company. If redemptions are paid in investment securities, such securities will
be valued as set forth in the Prospectus for the appropriate series, and a
redeeming shareholder would normally incur brokerage expenses if he converted
these securities to cash.
 
     No charge is made by the Company for redemptions. Any redemption may be
more or less than the shareholder's cost, depending on the market value of the
series' portfolio securities.
 
     SIGNATURE GUARANTEES.  To protect your account, the Company and Vanguard
from fraud, signature guarantees are required for certain redemptions. A
signature guarantee verifies the authenticity of your signature. Examples of
situations in which signature guarantees are required are: (1) ALL REDEMPTIONS,
REGARDLESS OF THE AMOUNT INVOLVED, WHEN THE PROCEEDS ARE TO BE PAID TO SOMEONE
OTHER THAN THE REGISTERED ACCOUNT 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 retirement 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 Company in certain instances.
 
     Signature guarantees can be obtained from a bank, broker or any other
guarantor that Vanguard deems acceptable. NOTARIES PUBLIC ARE NOT ACCEPTABLE
GUARANTORS.

                             YIELD AND TOTAL RETURN
 
     The yield of Vanguard/Windsor Fund for the thirty-day period ended October
31, 1995 was +3.09%, and the yield for Vanguard/Windsor II for the same period
was +3.16%.
 
     The average annual total returns for Vanguard/Windsor Fund for the one-,
five- and ten-year periods ending October 31, 1995 were +17.80%, +20.51% and
+13.93%, respectively. The average annual total returns for the one-, five- and
ten-year periods for Vanguard/Windsor II were +23.08%, +18.24% and +14.64%,
respectively. Total return is computed by determining 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.
 
                             INVESTMENT LIMITATIONS
 
     Each series of the Company 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 that series. A series will not:
 
     1) with respect to 75% of the value of its total assets, purchase the
        securities of any issuer (except obligations of the United States
        government and its instrumentalities) if as a result the series would
        hold more than 10% of the outstanding voting securities of the issuer,
        or more than 5% of the value of the total assets of the series would be
        invested in the securities of such issuer;
 
     2) invest in securities of other investment companies, except as may be
        acquired as a part of a merger, consolidation or acquisition of assets
        approved by the shareholders of the series or otherwise to the extent
        permitted by Section 12 of the Investment Company Act of 1940. A series
        will invest only in investment companies which have investment
        objectives and investment policies consistent with those of that series;
 
     3) borrow money, except that a series may borrow from banks (or through
        reverse repurchase agreements), for temporary or emergency (not
        leveraging) purposes, including the meeting of redemption requests which
        might otherwise require the untimely disposition of securities, in an
        amount not exceeding 10% of the value of the net assets of the series
        (including the amount borrowed and the value of any outstanding reverse
        repurchase agreements) at the time the borrowing is made. Whenever
        borrowings exceed 5% of the value of the net assets of the series, the
        series will not make any additional investments;
 
     4) purchase securities on margin, or sell securities short except that each
        series may invest in stock futures contracts, stock options and options
        on stock futures contracts to the extent that not more than 5% of a
        series' assets are required as deposit on a futures contract and not
        more than 20% of a series' assets are invested in futures contracts and
        options transactions at any time;
 
     5) 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
        (including any investment in The Vanguard Group, Inc.);
 
     6) invest for the purpose of exercising control over management of any
        company;
 
     7) purchase or retain securities of any company in which those Officers and
        Directors of the Company and/or its investment advisers owning more than
        1/2 of 1% of such securities, own in the aggregate more than 5% of such
        securities;
 
     8) make loans, except (i) by purchasing bonds, debentures or similar
        obligations (including repurchase agreements) which are either publicly
        distributed or customarily purchased by institutional investors, and
        (ii) as provided under "Lending of Securities" (See page B-2);
 
     9) purchase assessable securities;
 
   10) engage in the business of underwriting securities issued by other
       persons, except to the extent that the series may technically be deemed

THE VANGUARD GROUP
 
     The Company is a member of The Vanguard Group of Investment Companies.
Through their jointly-owned subsidiary, The Vanguard Group, Inc. ("Vanguard"),
the Company 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 certain 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.
 
     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
17 j-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 October 31, 1995,
Vanguard/Windsor Fund had contributed capital of $1,662,000 to Vanguard,
representing 8.3% of Vanguard's capitalization and, at that time,
Vanguard/Windsor II had contributed capital of $1,273,000 to Vanguard,
representing 6.4% of Vanguard's capitalization. The Funds' Service Agreement
provides for the following arrangement: (a) each Vanguard Fund may invest up to
0.40% of its current net 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 October 31, 1995, Vanguard/Windsor Fund's share of Vanguard's
actual net costs of operation relating to management and administrative services
(including transfer agency) totaled approximately $23,760,000 and Vanguard/
Windsor II's share of such costs of operation totaled approximately $20,622,000.
 
     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 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
 
                                      B-10
<PAGE>   105
 
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 2/100 of 1% of its average month-end net assets. During
the fiscal year ended October 31, 1995, Vanguard/Windsor Fund paid approximately
$1,875,000 of the Group's distribution and marketing expenses, which represented
an effective annual rate of .02 of 1% of Vanguard/Windsor Fund's average net
assets and Vanguard/Windsor II paid approximately $1,622,000 of such expenses
which represented an effective annual rate of .02 of 1% of Vanguard/Windsor II's
net assets.
 
     INVESTMENT ADVISORY SERVICES.  Vanguard also provides investment advisory
services to Vanguard Windsor II, Vanguard Money Market Reserves, Vanguard
Municipal Bond Fund, several Portfolios of Vanguard Fixed Income Securities
Fund, Vanguard Pennsylvania Tax-Free Fund, Vanguard California Tax-Free Fund,
Vanguard New York Insured Tax-Free Fund, Vanguard New Jersey Tax-Free Fund,
Vanguard Ohio Tax-Free Fund, Vanguard Florida Insured Tax-Free Fund, Vanguard
Index Trust, Vanguard Bond Index Fund, Vanguard International Equity Index Fund,
Vanguard Balanced Index Fund, Vanguard Institutional Portfolios, Vanguard
Admiral Funds, Vanguard Tax-Managed Fund, Aggressive Growth Portfolio of
Vanguard Horizon Fund, Vanguard Institutional Index Fund, several Portfolios of
Vanguard Variable Insurance Fund, a portion of Vanguard/Morgan Growth Fund as
well as several indexed separate accounts. These services are provided on an
at-cost basis by an investment management staff employed directly by Vanguard.
The compensation and other expenses of this staff are paid by the Funds
utilizing these services.
 
REMUNERATION OF DIRECTORS AND OFFICERS
 
     The Company pays each Director who is not also an Officer an annual fee
plus travel and other expenses incurred in attending Board meetings. The
Company's Officers and employees are paid by Vanguard which, in turn, is
reimbursed by the Company, and each other Fund in the Group, for its
proportionate share of Officers' and employees' salaries and retirement
benefits.
 
     Under its Retirement Plan, Vanguard contributes annually an amount equal to
10% of each Officer's annual compensation plus 5.7% of that part of the
Officer's compensation during the year, if any, that exceeds the Social Security
Taxable Wage Base then in effect. Under the Thrift Plan, all Officers are
permitted to make pre-tax basic contributions in a maximum amount equal to 4% of
total compensation. Vanguard matches the basic contributions on a 100% basis.
Upon retirement, Directors who are not Officers are paid an annual fee based on
the number of years of service on the Board, up to fifteen years of service. The
fee is equal to $1,000 for each year of service and each investment company
member of The Vanguard Group contributes a proportionate amount of this fee
based on its relative net assets. This fee is paid, subsequent to a Director's
retirement, for a period of ten years or until the death of a retired Director.

VANGUARD/WINDSOR FUND
 
     The Company employs Wellington Management Company ("WMC") under an
investment advisory agreement dated June 19, 1985 to manage the investment and
reinvestment of the assets of Vanguard/Windsor Fund and to continuously review,
supervise and administer Vanguard/Windsor Fund's investment program. WMC
discharges its responsibilities subject to the control of the Officers and
Directors of the Company. WMC is a Massachusetts general partnership controlled
by the following general partners: Robert W. Doran, Duncan M. McFarland and John
R. Ryan.
 
     Vanguard/Windsor 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 Vanguard/Windsor Fund's average month-end net assets for
the quarter.

     The basic fee paid to WMC may be increased or decreased by applying an

the thirty-six months preceding the end of the quarter relative to the
investment record of the Standard and Poor's Composite Stock Price Index (the
"S&P 500") for the same period. The schedule of incentive/penalty adjustments is
set forth in the Vanguard/Windsor Fund Prospectus.
 
     For purposes of incentive/penalty adjustments, the investment performance
of Vanguard/Windsor Fund for any period is expressed as a percentage of
Vanguard/Windsor Fund's net asset value per share at the beginning of the
period. This percentage is equal to the sum of: (i) the change in
Vanguard/Windsor Fund's net asset value per share during the period; (ii) the
value of Vanguard/Windsor Fund's cash distributions per share having an
ex-dividend date occurring within the period; and (iii) the per share amount of
capital gains taxes paid or accrued during the period by Vanguard/Windsor Fund
for undistributed realized long-term capital gains. The investment record of the
S&P Index for any period is expressed as a percentage of the S&P Index level at
the beginning of the period. This percentage is equal to the sum of (i) the
change in the level of the S&P Index, during the period and (ii) the value,
computed consistently with the S&P Index, of cash distributions having an
ex-dividend date occurring within the period made by companies whose securities
comprise the S&P Index.

     Vanguard/Windsor II pays BHM&S 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 average month-end net assets of Vanguard/Windsor II
managed by BHM&S for the quarter:

     Effective with the quarter ending April 30, 1996, the basic fee paid to
BHM&S will be increased or decreased by applying an adjustment formula based on
the investment performance of the assets of Vanguard/Windsor II managed by BHM&S
(the "BHM&S Portfolio"). Such formula provides for an increase or decrease in
the basic fee paid to BHM&S each quarter, depending upon the BHM&S Portfolio's
investment

performance for the thirty-six months preceding the end of the quarter relative
to the investment record of the Standard & Poor's/BARRA Value Index (the "BARRA
Value Index"). The schedule of incentive/penalty adjustments is set forth on the
Vanguard/Windsor II Prospectus.
 
     Until the quarter ending April 30, 1996, the incentive/penalty fee will be
calculated according to the following transition rules:
 
     (a) For the period May 1, 1993 to January 31, 1994 the incentive/penalty
         fee was not operable. During this period, Vanguard/Windsor II paid
         BHM&S the basic advisory fee set forth above.
 
     (b) Beginning with the quarter ending April 30, 1994, the incentive/penalty
         fee has been calculated based on a comparison of the investment
         performance of the BHM&S Portfolio and that of the BARRA Value Index
         over the number of months elapsed between May 1, 1993 and the end of
         the quarter for which the fee is being computed. The number of
         percentage points by which the investment performance of the BHM&S
         Portfolio must exceed or fall below that of the BARRA Value Index will
         increase proportionately from 3 percentage points and 2 percentage
         points, respectively, for the twelve months ended April 30, 1994 to 9
         percentage points and 6 percentage points, respectively for the
         thirty-six months ended April 30, 1996.
 
     The BARRA Value Index includes stocks in the Standard and Poor's 500
Composite Stock Price Index with lower than average ratios of market price to
book value. These types of stocks are often referred to as "value" stocks.
 
     The investment performance of the BHM&S Portfolio for any period is
expressed as a percentage of the "BHM&S Portfolio Unit Value" at the beginning
of such period. This percentage is equal to the sum of: (i) the change in the
BHM&S Portfolio Unit Value during such period; (ii) the unit value of the Fund's
cash distributions from the BHM&S Portfolio's net investment income and realized
net capital gains (whether long-term or short-term) having an ex-dividend date
occurring within such period; and (iii) the unit value of capital gains taxes
paid or accrued during such period by Vanguard/Windsor II for undistributed
realized long-term capital gains realized from the BHM&S Portfolio.
 
     The "BHM&S Portfolio Unit Value" will be determined by dividing the total
net assets of the BHM&S Portfolio by a given number of units. On the initial
date of the agreement, the number of units in the BHM&S Portfolio was equal to
the total shares outstanding of Vanguard/Windsor II. After such initial date, as
assets are added to or withdrawn from the BHM&S Portfolio, the number of units
of the BHM&S Portfolio will be adjusted based on the unit value of the BHM&S
Portfolio on the day such changes are executed.
 
     The investment record of the BARRA Value Index is calculated quarterly by
(i) multiplying the total return for the quarter (change in market price plus
dividends) of each stock included in the BARRA Value Index by its weighting in
the BARRA Value Index at the beginning of the quarter, and (ii) adding the
values discussed in (i). For any period, therefore, the investment record of the
BARRA Value Index will be the compounded quarterly returns of the BARRA Value
Index.
 
     During the fiscal years ended October 31, 1993, 1994 and 1995,
Vanguard/Windsor II paid advisory fees to BHM&S of approximately $6,488,000,
$7,518,000 and $8,514,842, respectively.

     The basic fee paid to Equinox may be increased or decreased by applying an
adjustment formula based on the investment performance of the portion of
Vanguard/Windsor II's assets managed by Equinox (the "Equinox Portfolio")
relative to the investment record of the Standard & Poor's 500 Composite Stock
Price Index ("S&P 500"). Such formula provides for an increase or decrease in
the basic fee paid to Equinox each quarter, depending upon the Equinox
Portfolio's investment performance for the thirty-six months preceding the end
of the quarter. The schedule of incentive/penalty fee adjustments is set forth
in the Vanguard/ Windsor II Prospectus.
 
     The investment performance of the Equinox Portfolio for any period is
expressed as a percentage of the "Equinox Portfolio Unit Value" at the beginning
of such period. This percentage is equal to the sum of: (i) the change in the
Equinox Portfolio Unit Value during such period; (ii) the unit value of the
Vanguard/Windsor II's cash distributions from the Equinox Portfolio net
investment income and realized net capital gains (whether long-term or
short-term) having an ex-dividend date occurring within such period; and (iii)
the unit value of capital gains taxes paid or accrued during such period by
Vanguard/Windsor II for undistributed realized long-term capital gains realized
from the Equinox Portfolio.
 
     The "Equinox Portfolio Unit Value" will be determined by dividing the total
net assets of the Equinox Portfolio by a given number of units. On the initial
date of the agreement, the number of units in the Equinox Portfolio was equal to
the total shares outstanding of Vanguard/Windsor II. After such initial date, as
assets are added to or withdrawn from the Equinox Portfolio, the number of units
of the Equinox Portfolio will be adjusted based on the unit value of the Equinox
Portfolio on the day such changes are executed.
 
     The investment record of the S&P 500 will be calculated quarterly by (i)
multiplying the total return for the quarter (change in the market price plus
dividends) of each stock included in the S&P 500 by its weighting in the S&P 500
at the beginning of the quarter, and (ii) adding the values discussed in (i).
For any period, therefore, the investment record of the S&P 500 will be the
compounded quarterly returns of the S&P too.
 
     During the fiscal years ended October 31, 1993, 1994 and 1995,
Vanguard/Windsor II paid advisory fees to Equinox of approximately $1,171,000,
$1,424,000 and $1,681,435, respectively.
 
TUKMAN
 
     Tukman is a Maryland corporation controlled by the following officers of
Tukman: Melvin T. Tukman, President and Director, and Daniel L. Grossman, Vice
President.
 
     Under the terms of an investment advisory agreement dated November 1, 1991,
the Fund pays Tukman 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 average month-end assets of the portion of the Vanguard/Windsor II's assets
managed by Tukman:

     The basic fee paid to Tukman may be increased or decreased by applying an
adjustment formula based on the investment performance of the portion of
Vanguard/Windsor II's assets managed by Tukman (the "Tukman Portfolio") relative
to the investment record of the Standard & Poor's 500 Composite Stock Price
Index ("S&P 500"). Such formula provides for an increase or decrease in the
basic fee paid to Tukman each quarter, depending upon the Tukman Portfolio's
investment performance for the thirty-six months preceding the end of the
quarter. The schedule of incentive/penalty fee adjustments is set forth in the
Vanguard/ Windsor II Prospectus.
 
     The investment performance of the Tukman Portfolio for any period is
expressed as a percentage of the "Tukman Portfolio Unit Value" at the beginning
of such period. The percentage is equal to the sum of: (i) the change in the
Tukman Portfolio Unit Value during such period; (ii) the unit value of
Vanguard/Windsor II's cash distributions from the Tukman Portfolio net
investment income and realized net capital gains (whether long-term or
short-term) having an ex-dividend date occurring within such period; and (iii)
the unit value of capital gains taxes paid or accrued during such period by
Vanguard/Windsor II for undistributed realized long-term capital gains realized
from the Tukman Portfolio.
 
     The "Tukman Portfolio Unit Value" will be determined by dividing the total
net assets of the Tukman Portfolio by a given number of units. On the initial
date of the agreement, the number of units in the Tukman Portfolio was equal to
the total shares outstanding of Vanguard/Windsor II. After such initial date, as
assets are added to or withdrawn from the Tukman Portfolio, the number of units
of the Tukman Portfolio will be adjusted based on the unit value of the Tukman
Portfolio on the day such changes are executed.
 
     The investment record of the S&P 500 will be calculated quarterly by (i)
multiplying the total return for the quarter (change in market price plus
dividends) of each stock included in the S&P 500 by its weighting in the S&P 500
at the beginning of the quarter, and (ii) adding the values discussed in (i).
For any period, therefore, the investment record of the S&P 500 will be the
compounded quarterly returns of the S&P 500.
 
     During the fiscal years ended October 31, 1993, 1994 and 1995,
Vanguard/Windsor II paid advisory fees to Tukman of approximately $1,503,000,
$1,825,000 and $2,184,838, respectively.
 
VANGUARD'S CORE MANAGEMENT GROUP
 
     Since November 1, 1991, Vanguard's Core Management Group has provided
investment advisory services on an at-cost basis with respect to a portion of
the Vanguard/Windsor II's equity allocation (currently approximately 8%). The
Core Management Group also provides investment advisory services to several
Vanguard Funds, including Vanguard Index Trust, Vanguard Balanced Index Fund,
Vanguard Horizon Fund, Vanguard International Equity Index Fund, Vanguard
Institutional Index Fund, several indexed separate accounts as well as a portion
of Vanguard/Morgan Growth Fund's assets. The quantitative approach used by
Vanguard's Core Management Department is designed to generate highly predictable
results relative to a benchmark of large and medium capitalization "value"
stocks. A portfolio is constructed from attractively priced "value" stocks using
an optimizer to assure that the characteristics of the portfolio are similar to
that of the benchmark. The Core Management Group is supervised by the Officers
of the Fund.
 
DURATION AND TERMINATION OF INVESTMENT ADVISORY AGREEMENTS
 
     Vanguard/Windsor Fund's present agreement with WMC continues in effect
until May 31, 1996. Vanguard/Windsor II's present agreements with BHM&S, Equinox
and Tukman continue in effect until April 30, 1996, October 31, 1996 and October
31, 1996, respectively. Each agreement is renewable for successive one-year
periods if specifically approved by a vote of the Company's Board of Directors
at a meeting called for the purpose of considering such approval. The Board's
approval must include the affirmative votes of a majority of the Directors who
are neither parties to the contract or "interested persons" of such parties (as
defined in the Investment Company Act of 1940). In addition, the question of
continuing an investment advisory agreement may be presented to shareholders. In
such an event, the agreement would be continued only if approved by the
affirmative vote of a majority of the outstanding shares of the Fund to which
the agreement related.
 
                                      B-16
<PAGE>   111
 
     Each investment advisory agreement is automatically terminated if assigned,
and may be terminated without penalty at any time (1) by majority vote of either
the Board of Directors or the Fund's outstanding shares upon 60 days' written
notice to the adviser, or (2) by the adviser upon 90 days' written notice to the
Fund.
 
     The Company'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; or
 
     (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 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.
 
MORE INFORMATION ON ADVISERS' INCENTIVE/PENALTY FEES
 
     In April 1972, the Securities and Exchange Commission ("SEC") issued
Release No. 7113 under the Investment Company Act of 1940 to call the attention
of directors and investment advisers to certain factors which must be considered
in connection with investment company incentive fee arrangements. One of these
factors is to "avoid basing significant fee adjustments upon random or
insignificant differences" between the investment performance of a fund and that
of the particular index with which it is being compared. The Release provides
that "preliminary studies (of the SEC staff) indicate that as a 'rule of thumb'
the performance difference should be at least 10 percentage points" annually
before the maximum performance adjustment may be made. However, the Release also
states that "because of the preliminary nature of these studies, the Commission
is not recommending, at this time, that any particular performance difference
exist before the maximum fee adjustment may be made." The Release concludes that
the directors of a fund "should satisfy themselves that the maximum performance
adjustment will be made only for performance differences that can reasonably be
considered significant." The Board of Directors has fully considered the SEC
Release and believes that the performance adjustments as included in the
agreements with WMC, BHM&S, Equinox and Tukman are entirely appropriate although
not within the 10 percentage points per year range suggested in the Release.
Under the Funds investment advisory agreements, the maximum performance
adjustments are made at a difference of 12 and 9 percentage points from the
performance of the respective index over a thirty-six month period, which would
effectively be the equivalent of approximately 4 and 3 percentage points
difference per year.
 
                             PORTFOLIO TRANSACTIONS
 
     WMC, BHM&S, Equinox, Tukman and Vanguard are authorized to (with the
approval of the Board of Directors) select the brokers or dealers that will
execute the purchases and sales of portfolio securities for the respective
series of the Company. The investment advisory agreements direct the advisers to
use their best efforts to obtain the best available price and most favorable
execution as to all transactions. Each investment adviser 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, each investment adviser 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
series and/or the investment adviser. Each investment adviser
 
                                      B-17
<PAGE>   112
 
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 agreements also incorporate the concepts of Section
28(e) of the Securities Exchange Act of 1934 by providing that, subject to the
approval of the Board of Directors, each investment adviser may cause the series
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 the adviser to the Company and the other Funds in the Group.
 
     Currently, it is the Company's policy that each investment adviser 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. An investment adviser will only pay such
higher commissions if it believes this to be in the best interest of the series.
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 investment adviser and/or the Company.
However, the investment advisers have informed the Company that they will not
pay higher commission rates specifically for the purpose of obtaining research
services.
 
     Since the Company does not market its shares through intermediary brokers
or dealers, it is not the Company's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be through such firms.
However, the Company may place portfolio orders with qualified broker-dealers
who recommend shares of the Company to other clients, or who act as agent in the
purchase of the Company'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 the Company's shares by a broker or
dealer in selecting among qualified broker-dealers.
 
     During the fiscal years ended October 31, 1993, 1994 and 1995 the Company
paid $14,909,648, $14,906,748 and $17,775,409 in brokerage commissions,
respectively.
 
     Some securities considered for investment by a series of the Company may
also be appropriate for the other series and for other Funds and/or clients
served by the investment adviser. If purchase or sale of securities consistent
with the investment policies of the series and one or more of these other Funds
or clients served by the investment adviser 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 the investment adviser.

     Vanguard may use reprinted material discussing The Vanguard Group, Inc. or

                    DESCRIPTION OF SHARES AND VOTING RIGHTS
 
     The Company was originally organized as a corporation in 1959. On January
2, 1985, the Company was reorganized into a Pennsylvania business trust which
was created solely for that purpose. The Company was reorganized as a Maryland
corporation on December 30, 1985. The Amended and Restated Articles of
Incorporation permit the Directors to issue 2,200,000,000 shares of common
stock, with one cent par value. The Board of Directors has the power to
designate one or more classes ("series") of shares of common stock and to
classify or reclassify any unissued shares with respect to such series.
Currently the Company is offering shares of two series.
 
     The shares of each series are fully paid and non-assessable, and have no
preference as to conversion, exchange, dividends, retirement or other features.
The shares of each series have no pre-emptive rights. Such shares have
non-cumulative voting rights, which means that the holders of more than 50% of
the shares voting for the election of Directors can elect 100% of the Directors
if they choose to do so. A shareholder is entitled to one vote for each full
share held (and a fractional vote for each fractional share held), then standing
in his name on the books of the Company. On any matter submitted to a vote of
shareholders, all shares of the Company then issued and outstanding and entitled
to vote, irrespective of the series, shall be voted in the aggregate and not by
series except; (i) when required by the Investment Company Act of 1940, shares
shall be voted by individual series; and (ii) when the matter does not affect
any interest of a particular series, then only shareholders of the affected
series shall be entitled to vote thereon.
