YIELD AND        From time to time the Fund may advertise its yield and total
TOTAL RETURN     return. Both yield and total return figures are based on his-
                 torical earnings and are not intended to indicate future per-
                 formance. The "total return" of the Fund refers to the aver-
                 age 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 in-
                 vested at the beginning of a stated period to the ending re-
                 deemable 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 in-
                 come 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 recur-
                 ring 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 re-
                 flect the income paid to your own account or the yield re-
                 ported in the Fund's reports to shareholders.

INVESTMENT       The objective of the Fund is to provide long-term growth of
OBJECTIVES       capital and income. The Fund's secondary objective is to pro-
                 vide current income. There can be no assurance that the Fund
                 will achieve these objectives.
 
THE FUND SEEKS   These investment objectives are fundamental and so cannot be
TO PROVIDE       changed without the approval of a majority of the Fund's    
LONG-TERM        shareholders.                                                
GROWTH OF
CAPITAL AND
INCOME
- --------------------------------------------------------------------------------
INVESTMENT       The Fund invests primarily in common stocks, which are se-
POLICIES         lected principally on the basis of fundamental investment
                 value. Crucial to the valuation process is the relationship
THE FUND         of a company's underlying earning power and dividend payout
INVESTS          to the market price of its stock. The Fund's holdings usually
PRIMARILY IN     are characterized by relatively low price-earnings ratios and
COMMON STOCKS    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 defen-
                 sive purposes. The Fund may also invest in stock futures con-
                 tracts and options. See "Implementation of Policies" for a
                 description of these investment practices of the Fund.
 
                 The investment policies of the Fund are not fundamental and
                 so may be changed by the Board of Directors without share-
                 holder approval.
- --------------------------------------------------------------------------------
INVESTMENT       As a mutual fund investing primarily in common stocks, the
RISKS            Fund is subject to MARKET RISK--i.e., the possibility that
                 common stock prices will decline over short or even extended
THE FUND IS      periods. The U.S. stock market has tended to be cyclical,
SUBJECT TO       with periods when common stock prices generally rise and pe-
MARKET RISK      riods 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 1994,
                 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 1994. While this average
                 return can be used as a guide for setting reasonable expecta-
                 tions 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 histori-
                 cal investment performance, which may be a poor guide to fu-
                 ture returns. Also, stock market indexes such as the S&P 500
                 are based on unmanaged portfolios of securities before trans-
                 action 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      The investment adviser manages the Fund according to the tra-
ALSO SUBJECT     ditional methods of "active" investment management, which in-

RISK             ic, financial and market analysis and investment judgement.
                 MANAGER RISK refers to the possibility that the Fund's in-
                 vestment 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       The Fund is intended for investors who are seeking growth of
INVEST           capital and income. Although the Fund's secondary objective
                 is to provide current income, investors should not consider
LONG-TERM        the Fund a substitute for fixed-income investments. The Fund
INVESTORS        is intended to be a long-term investment vehicle and is not
SEEKING GROWTH   designed to provide investors with a means of speculating on
OF CAPITAL AND   short-term market movements. Investors who engage in exces-
INCOME           sive 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 (in-
                 cluding exchange purchases from other Vanguard portfolios)
                 that is reasonably deemed to be disruptive to efficient port-
                 folio management, either because of the timing of the invest-
                 ment or previous excessive trading by the investor. Addition-
                 ally, 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 ob-
                 jectives 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
 
                                                                               5

                 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 in-
                 vestments.
- --------------------------------------------------------------------------------
IMPLEMENTATION   In addition to investing primarily in equity securities, the
OF POLICIES      Fund follows a number of additional investment practices to
                 achieve its objectives.
 
THE FUND MAY     Although it normally seeks to remain substantially fully in-
INVEST IN        vested in equity securities, the Fund may invest in certain
SHORT-TERM       short-term fixed income securities. Such securities may be
FIXED INCOME     used temporarily to invest uncommitted cash balances, to
SECURITIES       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' accept-
                 ances; and repurchase agreements collateralized by these se-
                 curities. In addition, the Fund may, on occasion, invest a
                 small portion of its assets in bonds with ratings below in-
                 vestment 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 securi-
                 ties at the Fund's cost plus interest within a specified pe-
                 riod (normally one day). In these transactions, the securi-
                 ties 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     The Fund may utilize stock futures contracts and options to a
USE FUTURES      limited extent. Specifically, the Fund may enter into futures
CONTRACTS AND    contracts provided that not more than 5% of its assets are
OPTIONS          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 as-
                 sets.
 
                 Futures and options transactions may be used for several rea-
                 sons: to maintain cash reserves while simulating full invest-
                 ment, to facilitate trading, to reduce transaction costs, or
                 to seek higher investment returns when a futures contract is
                 priced more attractively than the underlying equity security
                 or index. While futures contracts and options can be used as
                 leveraged investments, the Fund may not use futures or op-
                 tions transactions to leverage its net assets.
 
                 For example, in order to remain fully invested in stocks
                 while maintaining liquidity to meet potential shareholder re-
                 demptions, the Fund may invest a portion of its assets in a
                 stock futures contract. Because futures contracts only re-
                 quire 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.
 
FUTURES          The primary risks associated with the use of futures con-
CONTRACTS AND    tracts and options are: (i) imperfect correlation between the
OPTIONS POSE     change in market value of the stocks held by the Fund and the
CERTAIN RISKS    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 only in those contracts whose behavior
                 is expected to resemble that of the Fund's underlying securi-
                 ties. 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 strate-
                 gies 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.
 
THE FUND MAY     The Fund may lend its investment securities to qualified in-
LEND ITS         stitutional investors for either short-term or long-term pur-
SECURITIES       poses 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 de-
                 scribed below in Investment Limitations, for temporary or
                 emergency purposes, including the meeting of redemption re-
                 quests which might otherwise require the untimely disposition
                 of securities.
 
PORTFOLIO        Although it generally seeks to invest for the long term, the
TURNOVER IS      Fund retains the right to sell securities irrespective of how
NOT EXPECTED     long they have been held. It is anticipated that the annual
TO EXCEED 100%   portfolio turnover of the Fund will not exceed 100%. A turn-
                 over rate of 100% would occur, for example, if all of the se-
                 curities of the Fund were replaced within one year.
- --------------------------------------------------------------------------------
INVESTMENT       The Fund has adopted certain limitations on its investment
LIMITATIONS      practices. Specifically, the Fund will not:
               
THE FUND HAS     (a) with respect to 75% of the value of its total
ADOPTED              assets, purchase the securities of any issuer
CERTAIN              (except obligations of the United States govern-
FUNDAMENTAL          ment and its instrumentalities) if as a result
LIMITATIONS          the Fund would hold more than 10% of the out-
                     standing 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
 
 
                                                                               7
<PAGE>
 
                 (c) borrow money, except that the Fund may borrow
                     from banks (or through reverse repurchase agree-
                     ments), for temporary or emergency (not
                     leveraging) purposes, including the meeting of
                     redemption requests which might otherwise re-
                     quire 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 re-
                     verse 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 in-
                 vestment 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 is a member of The Vanguard Group of Investment Com-
THE FUND         panies, a family of more than 30 investment companies with
                 more than 80 distinct investment portfolios and total assets
VANGUARD         in excess of $130 billion. Through their jointly-owned sub-
ADMINISTERS      sidiary, The Vanguard Group, Inc. ("Vanguard"), the Fund and
AND              the other funds in the Group obtain at cost virtually all of
DISTRIBUTES      their corporate management, administrative and distribution
THE FUND         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 1994, the average expense ratio (annual
                 costs including advisory fees divided by total net assets)
                 for the Vanguard funds amounted to approximately .30% com-
                 pared to an average of 1.05% 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 Direc-
                 tors set broad policies for the Fund and choose its Officers.
                 A list of the Directors and Officers of the Fund and a state-
                 ment 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 admin-
                 istrative personnel needed to provide the requisite services
                 to the funds and also furnishes the funds with necessary of-
                 fice 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.

AS ADVISER TO
THE FUND      
                 WMC is a professional investment counseling firm which glob-
                 ally 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, 1994, WMC held discretionary management au-
                 thority with respect to more than $80 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.
                    
                 John B. Neff, Managing Partner of WMC, serves as portfolio
                 manager of the Fund, a position he has held since June of
                 1964. In managing the Fund's investments, Mr. Neff is as-
                 sisted by Charles T. Freeman, Senior Vice President of WMC
                 and assistant portfolio manager of the Fund, who joined WMC
                 in 1969. Messrs. Neff and Freeman are supported by research
                 and other investment services provided by the professional
                 staff of WMC.     
 
                 Effective at year-end 1995, Mr. Neff will retire and Mr.
                 Freeman will assume the position of portfolio manager of the
                 Fund. Mr. Neff will remain as an adviser to WMC, and will
                 continue 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:

                 During the fiscal year ended October 31, 1994, the total ad-
                 visory 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 .08% 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 rec-
                 ognition of brokerage services felt necessary for the
                 achievement of better execution, provided the adviser be-
                 lieves this to be in the best interest of the Fund. Although
                 the Fund does not market its shares through intermediary bro-
                 kers or dealers, the Fund may place orders with qualified
                 broker-dealers who recommend the Fund to clients if the Offi-
                 cers 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 in-
                 vestment 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 ad-
                 visory agreement; and (c) the continued employment of an ex-
                 isting 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 con-
                 cerning the adviser that would have normally been included in
                 a proxy statement.

PERFORMANCE      The table on table 11 provides investment results for the
RECORD           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 for the indicated periods. Also
                 included is comparative information with respect to the un-
                 managed Standard & Poor's 500 Composite Stock Price Index, a
                 widely used barometer of stock market activity, and the Con-
                 sumer Price Index, a statistical measure of changes in the
                 prices of goods and services. The table does not make any al-
                 lowance for federal, state or local income taxes which share-
                 holders 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 to-
                 day. This information is provided to help investors better
                 understand the Fund and may not provide a basis for compari-
                 son with other investments or mutual funds which use a dif-
                 ferent method to calculate performance.

DIVIDENDS,       The Fund expects to pay dividends from ordinary income semi-
CAPITAL GAINS    annually. Capital gains distributions, if any, will be made
AND TAXES        annually.
             
THE FUND PAYS    In addition, in order to satisfy certain distribution re-
SEMI- ANNUAL     quirements of the Tax Reform Act of 1986, the Fund may de-
DIVIDENDS AND    clare special year-end dividend and capital gains distribu-
ANY CAPITAL      tions during December. Such distributions, if received by
GAINS ANNUALLY   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 ex-
                 tent 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 gen-
 
                                                                              11
<PAGE>
 
                 erally 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 capi-
                 tal 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 consider-
                 ably from year to year; there will be no capital gains dis-
                 tributions in years when the Fund realizes net capital loss-
                 es.
 
                 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. Al-
                 so, 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 re-
                 turned 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   A sale of shares of the Fund is a taxable event and may re-
OR LOSS MAY BE   sult in a capital gain or loss. A capital gain or loss may be
REALIZED UPON    realized from an ordinary redemption of shares or an exchange
EXCHANGE OR      of shares between two mutual funds (or two portfolios of a
REDEMPTION       mutual fund).
 
                 Dividend distributions, capital gains distributions, and cap-
                 ital 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 share-
                 holders who have not complied with IRS taxpayer identifica-
                 tion regulations. You may avoid this withholding requirement
                 by certifying on your Account Registration Form your proper
                 Social Security or Employer Identification number and certi-
                 fying that you are not subject to backup withholding.
 
                 The Fund has obtained a Certificate of Authority to do busi-
                 ness as a foreign corporation in Pennsylvania and does busi-
                 ness 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 in-
                 vestment in the Fund. The Fund is managed without regard to
                 tax ramifications.

THE SHARE        The Fund's share price or "net asset value" per share is de-
PRICE OF THE     termined by dividing the total market value of the Fund's in-
FUND             vestments and other assets, less any liabilities, by the num-
                 ber of outstanding shares of the Fund. Net asset value per
                 share is calculated at the close of regular trading on the
                 New York Stock Exchange on each day the Exchange is open for
                 business.
 
                 Portfolio securities that are listed on a securities exchange
                 are valued at the latest quoted sales prices as of 4:00 p.m.
                 on the valuation date. 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 securi-
                 ties for which market quotations are readily available are
                 valued at the latest quoted bid price. Temporary cash invest-
                 ments are valued at amortized cost, which approximates market
                 value. Other assets and securities for which no quotations
                 are readily available are valued at fair value as determined
                 in good faith by the Directors. 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 Fund's share price can be found daily in the mutual fund
                 listings of most major newspapers under the heading of The
                 Vanguard Group.
- --------------------------------------------------------------------------------
GENERAL          The Company is a Maryland corporation. The Articles of Incor-
INFORMATION      poration permit the Directors to issue 1,600,000,000 shares
                 of common stock, with a one cent par value. The Board of Di-
                 rectors has the power to designate one or more classes ("se-
                 ries") of shares of common stock and to classify and reclas-
                 sify any unissued shares with respect to such series. Cur-
                 rently 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, ex-
                 change, 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 ap-
                 plicable law. An annual meeting will be held to vote on the
                 removal of a Director or Directors of the Company if re-
                 quested 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 Dis-
                 bursing Agent. Price Waterhouse LLP, serves as independent
                 accountants for the Fund and will audit its financial state-
                 ments annually. The Fund is not involved in any litigation.

OPENING AN       Currently, shares of the Fund are not being offered or sold
ACCOUNT AND      to new investors. Current shareholders of the Fund may make
PURCHASING       additional investments, but the aggregate amount of such in-
SHARES           vestments 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 invest-
                 ments, the Fund is intended to be a long-term investment ve-
                 hicle and is not designed to provide investors with a means
                 of speculating on short-term stock market movements. Conse-
                 quently the Fund reserves the right to reject any specific
                 purchase (or exchange purchase) request. The Fund also re-
                 serves the right to suspend the offering of shares for a pe-
                 riod of time.
 
                 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 com-
                 missions or 12b-1 fees).
 
ADDITIONAL       Subsequent investments by current shareholders may be made
INVESTMENTS      only by mail ($100 minimum), wire ($1,000 minimum), exchange
                 from another Vanguard Fund account, or Vanguard Fund Express.

                 partment (1-800-662-2739).

                 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

TAX CAUTION      Under federal tax laws, the Fund is required to distribute
                 net capital gains and dividend income to Fund shareholders.
INVESTORS        These distributions are made to all shareholders who own Fund
SHOULD ASK       shares as of the distribution's record date, regardless of
ABOUT THE        how long the shares have been owned. Purchasing shares just
TIMING OF        prior to the record date could have a significant impact on
CAPITAL GAINS    your tax liability for the year. For example, if you purchase
AND DIVIDEND     shares immediately prior to the record date of a sizable cap-
DISTRIBUTIONS    ital gain or income dividend distribution, you will be as-
BEFORE           sessed taxes
INVESTING     
              
 
                                                                              15

                 on the amount of the capital gain and/or dividend distribu-
                 tion later paid even though you owned the Fund shares for
                 just a short period of time. (Taxes are due on the distribu-
                 tions even if the dividend or gain is reinvested in addi-
                 tional 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 poten-
                 tial distributions before investing. The Fund's annual capi-
                 tal gains distribution normally occurs in December, while in-
                 come 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."

                 be reopened for UP TO ONE YEAR.
 
                 Redemption requests received by telephone prior to the regu-
                 lar close of the New York Stock Exchange (generally 4:00 p.m.
                 Eastern time) are processed on the day of receipt and the re-
                 demption 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 re-
                 ceipt and the proceeds are normally sent on the second busi-

                 mental to the best interests of the Fund's remaining share-
                 holders to make payment in cash, the Fund may pay redemption

                 readily marketable securities.

MINIMUM          Due to the relatively high cost of maintaining smaller ac-
ACCOUNT          counts, the Fund reserves the right to redeem shares in any
BALANCE          account that is below the minimum initial investment amount.
REQUIREMENT      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 be-
                 low the Fund's minimum account balance requirement. You would
                 then be allowed 60 days to make an additional investment be-

                 ment accounts, and Uniform Gifts/Transfers to Minors Act ac-
                 counts.)
 
                 The Fund's minimum account balance requirement will not apply
                 if your account falls below $3,000 solely as a result of de-
                 clining markets (i.e., a decline in a Fund's net asset val-
                 ue).

                   exchange. For a copy and for answers to any ques-
                   tions you may have, call our Investor Information
                   Department (1-800-662-7447).
 
                 . An exchange is treated as a redemption and a pur-
                   chase; 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.
 
                                                                              19

                   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 ex-
                 change, as deemed necessary, at any time.

EXCHANGE         The Fund's exchange privilege is not intended to afford
PRIVILEGE        shareholders a way to speculate on short-term movements in
LIMITATIONS      the market. Accordingly, in order to prevent excessive use of
                 the exchange privilege that may potentially disrupt the man-
                 agement of the Fund and increase transaction costs, the Fund
                 has established a policy of limiting excessive exchange ac-
                 tivity.
 
                 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 pur-
                 chases from other Vanguard portfolios) that is reasonably
                 deemed to be disruptive to efficient portfolio management.
- --------------------------------------------------------------------------------
IMPORTANT        The ability to initiate redemptions (except wire redemptions)
INFORMATION      and exchanges by telephone is automatically established on
ABOUT            your account unless you request in writing that telephone
TELEPHONE        transactions on your account not be permitted.
TRANSACTIONS
                 To protect your account from losses resulting from unautho-
                 rized 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.
 
                 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 au-
                 thenticity of transaction instructions received by telephone,
                 provided that reasonable security procedures have been fol-
                 lowed. Vanguard believes that the security procedures de-
                 scribed 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 ac-
                 count.

YIELD AND        From time to time the Fund may advertise its yield and total
TOTAL RETURN     return. Both yield and total return figures are based on his-
                 torical earnings and are not intended to indicate future per-
                 formance. The "total return" of the Fund refers to the aver-
                 age 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 in-
                 vested at the beginning of a stated period to the ending re-
                 deemable 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 in-
                 come 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 recur-
                 ring 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 re-
                 flect the income paid to your own account or the yield re-
                 ported in the Fund's reports to shareholders.

INVESTMENT       The Fund invests primarily in common stocks, which are se-
POLICIES         lected principally on the basis of fundamental investment
                 value. Crucial to the valuation process is the relationship
THE FUND         of a company's underlying earning power and dividend payout
INVESTS          to the market price of its stock. The Fund's holdings usually
PRIMARILY IN     are characterized by relatively low price-earnings ratios and
COMMON STOCKS    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 defen-
                 sive purposes. The Fund may also invest in stock futures con-
                 tracts and options. See "Implementation of Policies" for a
                 description of these investment practices of the Fund.
 
                 The investment policies of the Fund are not fundamental and
                 so may be changed by the Board of Directors without share-
                 holder approval.

INVESTMENT       As a mutual fund investing primarily in common stocks, the
RISKS            Fund is subject to MARKET RISK--i.e., the possibility that
                 common stock prices will decline over short or even extended
THE FUND IS      periods. The U.S. stock market has tended to be cyclical,
SUBJECT TO       with periods when common stock prices generally rise and pe-
MARKET RISK      riods 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 1994,

                 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 1994. While this average
                 return can be used as a guide for setting reasonable expecta-
                 tions 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 histori-
                 cal investment performance, which may be a poor guide to fu-
                 ture returns. Also, stock market indexes such as the S&P 500
                 are based on unmanaged portfolios of securities before trans-
                 action 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      The investment adviser manages the Fund according to the tra-
ALSO SUBJECT     ditional methods of "active" investment management, which in-
TO MANAGER       volve the buying and selling of securities based upon econom-
RISK             ic, financial and market analysis and investment judgement.
                 MANAGER RISK refers to the possibility that the Fund's in-
                 vestment 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       The Fund is intended for investors who are seeking growth of
INVEST           capital and income. Although the Fund's secondary objective
                 is to provide current income, investors should not consider
LONG-TERM        the Fund a substitute for fixed-income investments. The Fund
INVESTORS        is intended to be a long-term investment vehicle and is not
SEEKING GROWTH   designed to provide investors with a means of speculating on
OF CAPITAL AND   short-term market movements. Investors who engage in exces-
INCOME           sive 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 ob-
                 jectives 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 instru-
 
                                                                               5

                 ments. Investors may also wish to complement an investment in
                 the Fund with other types of common stock investments.
- --------------------------------------------------------------------------------
IMPLEMENTATION   In addition to investing primarily in equity securities, the
OF POLICIES      Fund follows a number of additional investment practices to
                 achieve its objectives.
 
THE FUND MAY     Although it normally seeks to remain substantially fully in-
INVEST IN        vested in equity securities, the Fund may invest in certain
SHORT-TERM       short-term fixed income securities. Such securities may be
FIXED INCOME     used temporarily to invest uncommitted cash balances, to
SECURITIES       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' accept-
                 ances; and repurchase agreements collateralized by these se-
                 curities. In addition, the Fund may, on occasion, invest a
                 small portion of its assets in bonds with ratings below in-
                 vestment 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 securi-
                 ties at the Fund's cost plus interest within a specified pe-
                 riod (normally one day). In these transactions, the securi-
                 ties 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     The Fund may utilize stock futures contracts and options to a
USE FUTURES      limited extent. Specifically, the Fund may enter into futures
CONTRACTS AND    contracts provided that not more than 5% of its assets are
OPTIONS          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 as-
                 sets.
 
                 Futures and options transactions may be used for several rea-
                 sons: to maintain cash reserves while simulating full invest-
                 ment, to facilitate trading, to reduce transaction costs, or
                 to seek higher investment returns when a futures contract is
                 priced more attractively than the underlying equity security
                 or index. While futures contracts and options can be used as
                 leveraged investments, the Fund may not use futures or op-
                 tions transactions to leverage its net assets.
 
                 For example, in order to remain fully invested in stocks
                 while maintaining liquidity to meet potential shareholder re-
                 demptions, the Fund may invest a portion of its assets in a
                 stock futures contract. Because futures contracts only re-
                 quire a small initial margin deposit, the Fund would than be
                 able to maintain a cash reserve for potential redemptions,
                 while at the same time remaining fully invested. Also, be-
                 cause the transaction costs of futures and options may be
 
6
<PAGE>
 
                 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.
 
FUTURES          The primary risks associated with the use of futures con-
CONTRACTS AND    tracts and options are: (i) imperfect correlation between the
OPTIONS POSE     change in market value of the stocks held by the Fund and the
CERTAIN RISKS    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 only in those contracts whose behavior
                 is expected to resemble that of the Fund's underlying securi-
                 ties. 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 strate-
                 gies 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.
 
THE FUND MAY     The Fund may lend its investment securities to qualified in-
LEND ITS         stitutional investors for either short-term or long-term pur-
SECURITIES       poses 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 de-
                 scribed below in Investment Limitations, for temporary or
                 emergency purposes, including the meeting of redemption re-
                 quests which might otherwise require the untimely disposition
                 of securities.
 
PORTFOLIO        Although it generally seeks to invest for the long term, the
TURNOVER IS      Fund retains the right to sell securities irrespective of how
NOT EXPECTED     long they have been held. It is anticipated that the annual
TO EXCEED 100%   portfolio turnover of the Fund will not exceed 100%. A turn-
                 over rate of 100% would occur, for example, if all of the se-
                 curities of the Fund were replaced within one year.
- --------------------------------------------------------------------------------
INVESTMENT       The Fund has adopted certain limitations on its investment
LIMITATIONS      practices. Specifically, the Fund will not:

LIMITATIONS          the outstanding voting securities of the issuer, or more
                     than 5% of the value of the total assets of the Fund

                 (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 re-

                     of any outstanding reverse repurchase agreements) at the
                     time the borrowing is made. Whenever borrowings exceed 5%

                 may be changed only with the approval of a majority of the
                 Fund's shareholders.

MANAGEMENT OF    The Fund is a member of The Vanguard Group of Investment Com-
THE FUND         panies, a family of more than 30 investment companies with
                 more than 80 distinct investment portfolios and total assets
VANGUARD         in excess of $130 billion. Through their jointly-owned sub-
ADMINISTERS      sidiary, The Vanguard Group, Inc. ("Vanguard"), the Fund and
AND              the other funds in the Group obtain at cost virtually all of
DISTRIBUTES      their corporate management, administrative and distribution
THE FUND         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 1994, the average expense ratio (annual
                 costs including advisory fees divided by total net assets)
                 for the Vanguard funds amounted to approximately .30% com-
                 pared to an average of 1.05% 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 Direc-
                 tors set broad policies for the Fund and choose its Officers.
                 A list of the Directors and Officers of the Fund and a state-
                 ment 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 admin-
                 istrative personnel needed to provide the requisite services
                 to the funds and also furnishes the funds with necessary of-
                 fice 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.

AS ADVISER TO
THE FUND         WMC is a professional investment counseling firm which glob-
                 ally 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, 1994 WMC held discretionary management au-
                 thority with respect to more than $80 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.
                    
                 John B. Neff, Managing Partner of WMC, serves as portfolio
                 manager of the Fund, a position he has held since June of
                 1964. In managing the Fund's investments, Mr. Neff is as-
                 sisted by Charles T. Freemen, Senior Vice President of WMC
                 and assistant portfolio manager of the Fund, who joined WMC
                 in 1969. Messrs. Neff and Freemen are supported by research
                 and other investment services provided by the professional
                 staff of WMC.     
 
                 Effective at year-end 1995, Mr. Neff will retire and Mr.
                 Freeman will assume the position of portfolio manager of the
                 Fund. Mr. Neff will remain as an adviser to WMC, and will

                 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:

                 During the fiscal year ended October 31, 1994, the total ad-
                 visory 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 .08% 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 rec-
                 ognition of brokerage services felt necessary for the
                 achievement of better execution, provided the adviser be-
                 lieves this to be in the best interest of the Fund. Although
                 the Fund does not market its shares through intermediary bro-
                 kers or dealers, the Fund may place orders with qualified
                 broker-dealers who recommend the Fund to clients if the Offi-
                 cers 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 in-
                 vestment 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 ad-
                 visory agreement; and (c) the continued employment of an ex-
                 isting 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 con-
                 cerning the adviser that would have normally been included in
                 a proxy statement.

                 The Fund expects to pay dividends from ordinary income semi-
DIVIDENDS,       annually. Capital gains distributions, if any, will be made
CAPITAL GAINS    annually. All dividend and capital gains distributions are
AND TAXES        automatically reinvested in additional shares of the Fund. In
                 order to satisfy certain distribution requirements of the
THE FUND PAYS    IRS, the Fund may also declare special year-end distributions
SEMI-ANNUAL      during December. The Fund intends to continue to qualify for
DIVIDENDS AND    taxation as a "regulated investment company" under the Inter-
ANY CAPITAL      nal Revenue Code so that it will not be subject to federal
GAINS ANNUALLY   income tax to the extent that its income is distributed to
                 its shareholders.
 
                 If you utilize the Fund as an investment option in an employ-
                 er-sponsored retirement or savings plan, dividend and capital
                 gains distributions from the Fund generally will not be sub-
                 ject to current taxation, but will accumulate on a tax-de-
                 ferred 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        The Fund's share price or "net asset value" per share is de-
PRICE OF THE     termined by dividing the total market value of the Fund's in-
FUND             vestments and other assets, less any liabilities, by the num-
                 ber of outstanding shares of the Fund. Net asset value per
                 share is calculated at the close of regular trading on the
                 New York Stock Exchange on each day the Exchange is open for

                 Portfolio securities that are listed on a securities exchange
                 are valued at the latest quoted sales prices as of 4:00 p.m.
                 on the valuation date. 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 securi-
                 ties for which market quotations are readily available are
                 valued at the latest quoted bid price. Temporary cash invest-
                 ments are valued at amortized cost, which approximates market
                 value. Other assets and securities for which no quotations
                 are readily available are valued at fair value as determined
                 in good faith by the Directors. Securities may be valued on

GENERAL          The Company is a Maryland corporation. The Articles of Incor-
INFORMATION      poration permit the Directors to issue 1,600,000,000 shares
                 of common stock, with a one cent par value. The Board of Di-
                 rectors has the power to designate one or more classes ("se-
                 ries") of shares of common stock and to classify and reclas-
                 sify any unissued shares with respect to such series. Cur-
                 rently the Company is offering shares of two series.
 
                 The shares of each series of the Company are fully paid and

                 the advertisement) that would equate an initial amount in-
                 vested at the beginning of a stated period to the ending re-
                 deemable 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 in-
                 come 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 recur-
                 ring 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 standard     
 
                                                                               3

                 ized 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 your own
                 account or the yield reported in the Fund's reports to share-
                 holders. Additionally, the Fund may compare its performance

INVESTMENT       The Fund follows a flexible investment strategy, emphasizing
POLICIES         income-producing stocks which the investment advisers believe
                 to be undervalued by the market at the time of purchase. Gen-
THE FUND         erally, these securities are characterized by below-average
INVESTS          price-earnings ratios relative to the stock market, as mea-
PRIMARILY IN     sured by the Standard & Poor's Composite Stock Price Index.
COMMON STOCKS    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 statisti-
                 cal 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 substan-
                 tially 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 investment policies of the Fund are not fundamental and
                 so may be changed by the Board of Directors without share-
                 holder approval.

INVESTMENT       As a mutual fund investing primarily in common stocks, the

                 common stock prices will decline over short or even extended
THE FUND IS      periods. The U.S. stock market has tended to be cyclical,

                 table sets forth the extremes for stock market returns as
                 well as the average return for the period from 1926 to 1994,
                 as measured by the Standard & Poor's 500 Composite Stock

                 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 1994. While this average
                 return can be used as a guide for setting reasonable expecta-
                 tions 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 histori-
                 cal investment performance, which may be a poor guide to fu-
                 ture returns. Also, stock market indexes such as the S&P 500
                 are based on unmanaged portfolios of securities before trans-
                 action 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      The investment adviser manages the Fund according to the tra-
ALSO SUBJECT     ditional methods of "active" investment management, which in-

                 MANAGER RISK refers to the possibility that the Fund's in-
                 vestment 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       The Fund is intended for investors who are seeking growth of
INVEST           capital and income. Although the Fund's secondary objective
                 is to provide current income, investors should not consider
LONG-TERM        the Fund a substitute for fixed-income investments. The Fund
INVESTORS        is intended to be a long-term investment vehicle and is not
SEEKING GROWTH   designed to provide investors with a means of speculating on
OF CAPITAL AND   short-term market movements. Investors who engage in exces-
INCOME           sive 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 (in-
                 cluding exchange purchases from other Vanguard portfolios)
                 that is reasonably deemed to be disruptive to efficient

                 portfolio management, either because of the timing of the in-
                 vestment or previous excessive trading by the investor. Addi-
                 tionally 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 ob-
                 jectives 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   In addition to investing primarily in equity securities, the
OF POLICIES      Fund follows a number of additional investment practices to
                 achieve its objectives.
 
THE FUND MAY     Although it normally seeks to remain substantially fully in-
INVEST IN        vested in equity securities, the Fund may invest temporarily 
SHORT-TERM       in certain short-term fixed income securities. Such securi-  
FIXED INCOME     ties may be used to invest uncommitted cash balances, to     
SECURITIES       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' accept-    
                 ances; and repurchase agreements collateralized by these se- 
                 curities.                                                    
                                                                              
                 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 securi-
                 ties at the Fund's cost plus interest within a specified pe-
                 riod (normally one day). In these transactions, the securi-
                 ties 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     The Fund may utilize stock futures contracts and options to a
USE FUTURES      limited extent. Specifically, the Fund may enter into futures
CONTRACTS AND    contracts provided that not more than 5% of its assets are
OPTIONS          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 as-
                 sets.
 
                 Futures and options transactions may be used for several rea-
                 sons: to maintain cash reserves while simulating full invest-
                 ment, to facilitate trading, to reduce
 
6
<PAGE>
 
                 transaction costs, or to seek higher investment returns when
                 a futures contract is priced more attractively than the un-
                 derlying equity security or index. While futures contracts
                 and options can be used as leveraged investments, the Fund
                 may not use futures contracts or options transactions to lev-
                 erage its net assets.
 
                 For example, in order to remain fully invested in stocks
                 while maintaining liquidity to meet potential shareholder re-
                 demptions, the Fund may invest a portion of its assets in a
                 stock futures contract. Because futures contracts only re-
                 quire 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, be-
                 cause 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.
 
FUTURES          The primary risks associated with the use of futures con-
CONTRACTS AND    tracts and options are: (i) imperfect correlation between the
OPTIONS POSE     change in market value of the stocks held by the Fund and the
CERTAIN RISKS    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 only in those contracts whose behavior
                 is expected to resemble that of the Fund's underlying securi-
                 ties. 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 strate-
                 gies 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.
 
THE FUND MAY     The Fund may lend its investment securities to qualified in-
LEND ITS         stitutional investors for either short-term or long-term pur-
SECURITIES       poses 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 de-
                 scribed below in Investment Limitations, for temporary or
                 emergency purposes, including the meeting of redemption re-
                 quests which might otherwise require the untimely disposition
                 of securities.
 
PORTFOLIO        Although it generally seeks to invest for the long term, the
TURNOVER IS      Fund retains the right to sell securities irrespective of how
NOT EXPECTED     long they have been held. It is anticipated that the annual
TO EXCEED 100%   portfolio turnover of the Fund will not exceed 100%. A turn-
                 over rate of 100% would occur, for example, if all of the se-
                 curities of the Fund were replaced within one year.

INVESTMENT       The Fund has adopted certain limitations on its investment
LIMITATIONS      practices. Specifically, the Fund will not:
 
THE FUND HAS     (a) with respect to 75% of the value of its total assets,
ADOPTED              purchase the securities of any issuer (except obligations
CERTAIN              of the United States government and its instrumentali-
FUNDAMENTAL          ties) if as a result the Fund would hold more than 10% of
LIMITATIONS          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 re-
                     quire 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 in-
                 vestment 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.

                 on an at-cost basis to certain Vanguard funds, including
                 Vanguard/Windsor II. As a result of Vanguard's unique corpo-
                 rate structure, the Vanguard funds have costs substantially
                 lower than those of most competing mutual funds. In 1994, the
                 average expense ratio (annual costs including advisory fees
                 divided by total net assets) for the Vanguard funds amounted
                 to approximately .30% compared to an average of 1.05% 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 Direc-
                 tors set broad policies for the Fund and choose its Officers.

                 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, au-
                 diting 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.

                 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

                 .19 of 1% and .25 of 1% of the average net assets managed by

                 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 recogni-
                 tion of brokerage services deemed necessary for the achieve-
                 ment 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 in-
                 vestment 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 ad-
                 visory agreement; and (c) the continued employment of an ex-

PERFORMANCE      The table on page 14 provides investment results for the Fund
RECORD           for several periods throughout the Fund's lifetime. The re-
                 sults shown represent "total return" investment performance,
                 which assumes the reinvestment of all capital gains and in-
                 come dividends for the indicated periods. Also included is
                 comparative information with respect to the unmanaged Stan-
                 dard & 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.

DIVIDENDS,       The Fund expects to pay dividends from ordinary income semi-
CAPITAL GAINS    annually. Capital gains distributions, if any, will be made
AND TAXES        annually.
 
THE FUND PAYS    In addition, in order to satisfy certain distribution re-
SEMI-ANNUAL      quirements of the Tax Reform Act of 1986, the Fund may de-
DIVIDENDS AND    clare special year-end dividend and capital gains distribu-
ANY CAPITAL      tions during December. Such distributions, if received by
GAINS ANNUALLY   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. Divi-
                 dends 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 in-
                 vestors, dividends from net investment income will generally
                 qualify in part for the corporate dividends received deduc-
                 tion. However, the portion of the dividends so qualified de-
                 pends on the aggregate taxable qualifying dividend income re-
                 ceived 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 capi-
                 tal 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
 
14
<PAGE>
 
                 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. Al-
                 so, 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 re-
                 turned 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   A sale of shares of the Fund is a taxable event, and may re-
OR LOSS MAY BE   sult in a capital gain or loss. A capital gain or loss may be
REALIZED UPON    realized from an ordinary redemption of shares or an exchange
EXCHANGE OR      of shares between two mutual funds (or two portfolios of a
REDEMPTION       mutual fund).
 
                 Dividend distributions, capital gains distributions, and cap-
                 ital 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 share-
                 holders who have not complied with IRS taxpayer identifica-
                 tion regulations. You may avoid this withholding requirement
                 by certifying on your Account Registration Form your proper
                 Social Security or Employer Identification number and certi-
                 fying that you are not subject to backup withholding.
 
                 The Fund has obtained a Certificate of Authority to do busi-
                 ness as a foreign corporation in Pennsylvania and does busi-
                 ness 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 in-
                 vestment in the Fund. The Fund is managed without regard to
                 tax ramifications.
- --------------------------------------------------------------------------------
THE SHARE        The Fund's share price or "net asset value" per share is de-
PRICE OF THE     termined by dividing the total market value of the Fund's in-
FUND             vestments and other assets, less any liabilities, by the num-
                 ber of outstanding shares of the Fund. Net asset value per
                 share is calculated at the close of regular trading on the
                 New York Stock Exchange on each day the Exchange is open for
                 business.
 
                 Portfolio securities that are listed on a securities exchange
                 are valued at the latest quoted sales prices as of 4:00 p.m.
                 on the valuation date. 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
 
                                                                              15

                 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. Temporary cash investments are val-
                 ued at amortized cost, which approximates market value. Other
                 assets and securities for which no quotations are readily
                 available are valued at fair value as determined in good
                 faith by the Directors. 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 Fund's share price can be found daily in the mutual fund
                 listings of most major newspapers under the heading of The
                 Vanguard Group.

GENERAL          The Company is a Maryland corporation. The Articles of Incor-
INFORMATION      poration permit the Directors to issue 1,600,000,000 shares
                 of common stock, with a one cent par value. The Board of Di-
                 rectors has the power to designate one or more classes ("se-
                 ries') of shares of common stock and to classify or reclas-
                 sify any unissued shares with respect to such series. Cur-
                 rently 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, ex-
                 change, 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 ap-
                 plicable law. An annual meeting will be held to vote on the
                 removal of a Director or Directors of the Company if re-
                 quested 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 Dis-
                 bursing Agent. Price Waterhouse LLP, serves as independent
                 accountants for the Fund and will audit its financial state-
                 ments annually. The Fund is not involved in any litigation.

                 partment (1-800-662-2739).
 
                 In addition, an option to invest your cash dividend 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

TAX CAUTION      Under federal tax laws, the Fund is required to distribute
                 net capital gains and dividend income to Fund shareholders.
INVESTORS        These distributions are made to all shareholders who own Fund
SHOULD ASK       shares as of the distribution's record date, regardless of
ABOUT THE        how long the shares have been owned. Purchasing shares just
TIMING OF        prior to the record date could have a significant impact on
CAPITAL GAINS    your tax liability for the year. For example, if you purchase
AND DIVIDEND     shares immediately prior to the record date of a sizable cap-
DISTRIBUTIONS    ital gain or income dividend distribution, you will be as-
BEFORE           sessed taxes on the amount of the capital gain and/or divi-
INVESTING        dend 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 in-
                 vestment 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 implica-
                 tions the timing of your purchase may have.
 
                 Prospective investors should, therefore, inquire about poten-
                 tial distributions before investing. The Fund's annual capi-
                 tal gains distribution normally occurs in December, while in-
                 come 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."

VANGUARD'S       If you make a redemption from a qualifying account, Vanguard
AVERAGE COST     will send you an Average Cost Statement which provides you
STATEMENT        with the tax basis of the shares you redeemed. Please see
                 "Other Vanguard Services" for additional information.

MINIMUM          Due to the relatively high cost of maintaining smaller ac-
ACCOUNT          counts, the Fund reserves the right to redeem shares in any
BALANCE          account that is below the minimum initial investment amount
REQUIREMENT      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 ac-
                 count is below the Fund's minimum account balance require-
                 ment. 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. (This minimum
                 does not apply to IRAs, certain other retirement accounts,
                 and Uniform Gifts/Transfers to Minors Act accounts.)
 
                 The Fund's minimum account balance requirement will not apply
                 if your account falls below $3,000 solely as a result of de-
                 clining markets (i.e., a decline in a Fund's net asset val-
                 ue).

                   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.
 
                 . 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 ex-
                 change, 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 registra-
                 tion.
- --------------------------------------------------------------------------------
EXCHANGE         The Fund's exchange privilege is not intended to afford
PRIVILEGE        shareholders a way to speculate on short-term movements in
LIMITATIONS      the market. Accordingly, in order to prevent excessive use of
                 the exchange privilege that may potentially disrupt the man-
                 agement of the Fund and increase transaction costs, the Fund
                 has established a policy of limiting excessive exchange ac-
                 tivity.
 
                 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 pur-
                 chases from other Vanguard portfolios) that is reasonably
                 deemed to be disruptive to efficient portfolio management.
- --------------------------------------------------------------------------------
IMPORTANT        The ability to initiate redemptions (except wire redemptions)
INFORMATION      and exchanges by telephone is automatically established on
ABOUT            your account unless you request in writing that telephone
TELEPHONE        transactions on your account not be permitted.
TRANSACTIONS 
                 To protect your account from losses resulting from unautho-
                 rized or fraudulent telephone instructions, Vanguard adheres
                 to the following security procedures:
 
 
                                                                              23
<PAGE>
 
                 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.
 
                 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 au-
                 thenticity of transaction instructions received by telephone,
                 provided that reasonable security procedures have been fol-
                 lowed. Vanguard believes that the security procedures de-
                 scribed 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 ac-
                 count.

YIELD AND        From time to time the Fund may advertise its yield and total
TOTAL RETURN     return. Both yield and total return figures are based on his-
                 torical earnings and are not intended to indicate future per-
                 formance. The "total return" of the Fund refers to the aver-
                 age 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 in-
                 vested at the beginning of a stated period to the ending re-
                 deemable 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 invest-
                 ment 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 ap-
                 plied to all shareholder accounts. The yield calculation as-
                 sumes 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 main-
                 tain its books and
 
                                                                               3

                 records, and so the advertised 30-day yield may not fully re-
                 flect the income paid to your own account or the yield re-
                 ported in the Fund's reports to shareholders. Additionally,
                 the Fund may compare its performance to that of the Standard
                 & Poor's 500 Composite Stock Price Index ("S&P 500").

INVESTMENT       The objective of the Fund is to provide long-term growth of

INVESTMENT       The Fund follows a flexible investment strategy, emphasizing
POLICIES         income-producing stocks which the investment advisers believe
                 to be undervalued by the market at the time of purchase. Gen-
THE FUND         erally, these securities are characterized by below-average
INVESTS          price-earnings ratios relative to the stock market, as mea-
PRIMARILY IN     sured by the Standard & Poor's 500 Composite Stock Price In-
COMMON STOCKS    dex. 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 statisti-
                 cal 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 substan-
                 tially 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 investment policies of the Fund are not fundamental and
                 so may be changed by the Board of Directors without share-
                 holder approval.

INVESTMENT       As a mutual fund investing primarily in common stocks, the
RISKS            Fund is subject to MARKET RISK--i.e., the possibility that
                 common stock prices will decline over short or even extended

                 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 1994. While this average
                 return can be used as a guide for setting reasonable expecta-
                 tions 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 histori-
                 cal investment performance, which may be a poor guide to fu-
                 ture returns. Also, stock market indexes such as the S&P 500
                 are based on unmanaged portfolios of securities before trans-
                 action 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      The investment adviser manages the Fund according to the tra-

TO MANAGER       volve the buying and selling of securities based upon econom-
RISK             ic, financial and market analysis and investment judgement.
                 MANAGER RISK refers to the possibility that the Fund's in-
                 vestment 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       The Fund is intended for investors who are seeking growth of
INVEST           capital and income. Although the Fund's secondary objective
                 is to provide current income, investors should not consider
LONG-TERM        the Fund a substitute for fixed-income investments. The Fund
INVESTORS        is intended to be a long-term investment vehicle and is not
SEEKING GROWTH   designed to provide investors with a means of speculating on
OF CAPITAL AND   short-term stock market movements. Investors who engage in
INCOME           excessive account activity generate additional costs which
                 are borne by all of the Fund's shareholders. In order to min-
                 imize such costs, the Fund has adopted certain policies. The
                 Fund reserves the right to reject any purchase request (in-
                 cluding exchange purchases from other Vanguard portfolios)
                 that is reasonably deemed to be disruptive to efficient port-
                 folio management, either because of the timing of the invest-
                 ment or
 
 
                                                                               5

                 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 ob-
                 jectives 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   In addition to investing primarily in equity securities, the
OF POLICIES      Fund follows a number of additional investment practices to
                 achieve its objectives.
             
THE FUND MAY     Although it normally seeks to remain substantially fully in-
INVEST IN        vested in equity securities, the Fund may invest temporarily
SHORT-TERM       in certain short-term fixed income securities. Such securi-
FIXED INCOME     ties may be used to invest uncommitted cash balances, to
SECURITIES       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 repur-
                 chase 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 securi-
                 ties at the Fund's cost plus interest within a specified pe-
                 riod (normally one day). In these transactions, the securi-
                 ties 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     The Fund may utilize stock futures contracts and options to a
USE FUTURES      limited extent. Specifically, the Fund may enter into futures
CONTRACTS AND    contracts provided that not more than 5% of its assets are
OPTIONS          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 as-
                 sets.
 
                 Futures and options transactions may be used for several rea-
                 sons: to maintain cash reserves while simulating full invest-
                 ment, to facilitate trading, to reduce transaction costs, or
                 to seek higher investment returns when a futures contract is
                 priced more attractively than the underlying equity security
                 or index. While
 
6
<PAGE>
 
                 futures contracts and options can be used as leveraged in-
                 vestments, the Fund may not use futures contracts 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 re-
                 demptions, the Fund may invest a portion of its assets in a
                 stock futures contract. Because futures contracts only re-
                 quire 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, be-
                 cause 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.
 
FUTURES          The primary risks associated with the use of futures con-
CONTRACTS AND    tracts and options are: (i) imperfect correlation between the
OPTIONS POSE     change in market value of the stocks held by the Fund and the
CERTAIN RISKS    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 only in those contracts whose behavior
                 is expected to resemble that the Fund's underlying securi-
                 ties. 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 strate-
                 gies 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.
 
THE FUND MAY     The Fund may lend its investment securities to qualified in-
LEND ITS         stitutional investors for either short-term or long-term pur-
SECURITIES       poses 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 de-
                 scribed on page 8 in Investment Limitations, for temporary or
                 emergency purposes, including the meeting of redemption re-
                 quests which might otherwise require the untimely disposition
                 of securities.     
 
PORTFOLIO        Although it generally seeks to invest for the long term, the
TURNOVER IS      Fund retains the right to sell securities irrespective of how
NOT EXPECTED     long they have been held. It is anticipated that the annual
TO EXCEED 100%   portfolio turnover of the Fund will not exceed 100%. A turn-
                 over rate of 100% would occur, for example, if all of the se-
                 curities of the Fund were replaced within one year.

INVESTMENT       The Fund has adopted certain limitations on its investment
LIMITATIONS      practices. Specifically, the Fund will not:
 
THE FUND HAS     (a) with respect to 75% of the value of its total assets,
ADOPTED              purchase the securities of any issuer (except obligations
CERTAIN              of the United States government and its instrumentali-
FUNDAMENTAL          ties) if as a result the Fund would hold more than 10% of
LIMITATIONS          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 re-
                     quire 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 in-
                 vestment 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 is a member of The Vanguard Group of Investment Com-
THE FUND         panies, a family of more than 30 investment companies with
                 more than 80 distinct investment portfolios and total assets
VANGUARD         in excess of $130 billion. Through their jointly-owned sub-
ADMINISTERS      sidiary, The Vanguard Group, Inc. ("Vanguard"), the Fund and
AND              the other funds in the Group obtain at cost virtually all of

THE FUND         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 corpo-
                 rate structure, the Vanguard funds have costs substantially
                 lower than those of most competing mutual funds. In 1994, the
                 average expense ratio (annual costs including advisory fees
                 divided by total net assets) for the Vanguard funds amounted
                 to approximately .30% compared to an average of 1.05% 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 Direc-
                 tors set broad policies for the Fund and choose its Officers.
                 A list of the Directors and Officers of the Fund and a state-
                 ment 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 admin-
                 istrative personnel needed to provide the requisite services
                 to the funds and also furnishes

                 the funds with necessary office space, furnishings and equip-
                 ment. 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, au-
                 diting 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.

                 of the Fund's assets will be managed on an at cost basis by
                 Vanguard's Core Management Group. Neither BHM&S, Equinox nor

                 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 assets of the Fund,
                 Equinox and Tukman manage approximately 10% each and Van-
                 guard's Core Management Group manages approximately 8% of the
                 Fund's assets. Investors will be advised of any substantive
                 changes in the proportions managed by each adviser. Each ad-
                 viser discharges their responsibilities subject to the con-
                 trol of the Directors and Officers.
 
BARROW,          The Fund has entered into an advisory agreement with BHM&S

STRAUSS          and continuously reviews, supervises, and administers the
(BHM&S)          Fund's investment program with respect to those assets. BHM&S
                 discharges its responsibilities subject to the control of the
                 Officers and Directors of the Fund.

                 1994, BHM&S held discretionary management authority with re-
                 spect to approximately $13.7 billion of assets.
 
                 The investment principals at BHM&S develop a common, firm-
                 wide investment strategy that is employed in managing client
                 investment portfolios and selecting individual securities for
                 those portfolios. James P. Barrow, a founding principal and
                 Vice President of BHM&S, has been designated as portfolio
                 manager for the assets of the Fund managed by BHM&S, a posi-

VANGUARD'S CORE  Vanguard's Core Management Group provides investment advisory
MANAGEMENT       services on an at-cost basis with respect to a portion of the
GROUP            Fund's assets (currently approximately 8%). The Core Manage-
                 ment Group also provides investment advisory services to sev-
                 eral Vanguard funds, including Vanguard Index Trust, Vanguard
                 Balanced Index Fund, Vanguard International Equity Index
                 Fund, Vanguard Institutional Index Fund, several indexed sep-
                 arate accounts, as well as a portion of Vanguard/Morgan
                 Growth Fund's assets. Total assets under management by the
                 Core Management Group were approximately $18 billion as of
                 December 31, 1994. The portion of the Fund allocated to the
                 Core Management Group is managed using computerized, quanti-
                 tative techniques based on a value index constructed to ap-
                 proximate the aggregate fundamental characteristics of a typ-
                 ical large capitalization-value fund such as 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        For the fiscal year ended October 31, 1994, the investment
ADVISORY FEES    advisory fees paid by the Fund to BHM&S, Equinox and Tukman
PAID BY THE      represented an effective annual rate of .14 of 1% of average

                 mance. The investment advisory fees paid by the Fund for this
                 period to BHM&S represented an effective annual rate of .14

                 ment advisory fees paid by the Fund for the period to Equinox

                 and Tukman, respectively.     
                    
OTHER ADVISORY   BHM&S, Equinox, Tukman and Vanguard's Core Management Group
INFORMATION      are authorized to select brokers or dealers to execute pur-
                 chases and sales of the Fund's portfolio securities, and di-
                 rected to use their best efforts to obtain the best available
                 price and most favorable execution with respect to all trans-
                 actions. The full

                 range and quality of brokerage services available are consid-
                 ered in making these determinations.
 
                 The Fund has authorized BHM&S, Equinox, Tukman and Vanguard's
                 Core Management Group to pay higher commissions in recogni-
                 tion of brokerage services deemed necessary for the achieve-
                 ment 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 in-
                 vestment 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 ad-
                 visory agreement; and (c) the continued employment of an ex-
                 isting 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 con-
                 cerning the adviser that would have normally been included in
                 a proxy statement.

PERFORMANCE      The table on page 14 provides investment results for the Fund
RECORD           for several periods throughout the Fund's lifetime. The re-
                 sults shown represent "total return" investment performance
                 which assumes the reinvestment of all capital gains and in-
                 come dividends for the indicated periods. Also included is
                 comparative information with respect to the unmanaged Stan-
                 dard & 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.

                 The Fund expects to pay dividends from ordinary income semi-
DIVIDENDS,       annually. Capital gains distributions, if any, will be made
CAPITAL GAINS    annually. All dividend and capital gains distributions are
AND TAXES        automatically reinvested in additional shares of the Fund. In
                 order to satisfy certain distribution requirements of the
THE FUND PAYS    IRS, the Fund may also declare special year-end distributions
SEMI-ANNUAL      during December. The Fund intends to continue to qualify as a
DIVIDENDS AND    "regulated investment company" under the Internal Revenue
ANY CAPITAL      Code so that it will not be subject to federal income tax to
GAINS ANNUALLY   the extent that its income is distributed to its sharehold-
                 ers.
 
                 If you utilize the Fund as an investment option in an employ-
                 er-sponsored retirement savings plan, dividend and capital
                 gains distributions from the Fund generally will not be sub-
                 ject to current taxation, but will accumulate on a tax-de-
                 ferred 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        The Fund's share price or "net asset value" per share is de-
PRICE OF THE     termined by dividing the total market value of the Fund's in-
FUND             vestments and other assets, less any liabilities, by the num-
                 ber of outstanding shares of the Fund. Net asset value per
                 share is calculated at the close of regular trading on the
                 New York Stock Exchange on each date the Exchange is open for
                 business.
 
                 Portfolio securities that are listed on a securities exchange
                 are valued at the latest quoted sales prices as of 4:00 p.m.
                 on the valuation date. 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 securi-
                 ties for which market quotations are readily available are
                 valued at the latest quoted bid price. Temporary cash invest-
                 ments are valued at amortized cost, which approximates market
                 value. Other assets and securities for which no quotations
                 are readily available are valued at fair value as determined
                 in good faith by the Directors. Securities may be valued on
                 the basis of
 
14

                 prices provided by a pricing service when such prices are be-
                 lieved to reflect the fair market value of such securities.
 
                 The Fund's share price can be found daily in the mutual fund
                 listings of most major newspapers under the heading of The
                 Vanguard Group.

INFORMATION      poration permit the Directors to issue 1,600,000,000 shares
                 of common stock, with a one cent par value. The Board of Di-
                 rectors has the power to designate one or more classes ("se-
                 ries") of shares of common stock and to classify or reclas-
                 sify any unissued shares with respect to such series. Cur-
                 rently the Company is offering shares of two series.

                 change, 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 ap-
                 plicable law. An annual meeting will be held to vote on the
                 removal of a Director or Directors of the Company if re-
                 quested 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

  Vanguard/Windsor Funds, Inc. (the "Company") is an open-end, diversified,
management investment company whose shares are currently offered in two sepa-
rate series--the Vanguard/Windsor Fund series and the Vanguard/Windsor II se-
ries. 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 in-
vestment 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., ("Van-
guard") 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
 
                                                                            B-1

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 for each of its last ten fiscal years and the
Vanguard/Windsor II series for the period June 24, 1985 to October 31, 1985
and each of the fiscal years in the period ended October 31, 1994 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, or for which there are no readily
available market quotations.     
 
  The use of repurchase agreements involves certain risks. For example, if the
seller of the securities under an agreement defaults on its obligation to re-
purchase the underlying securities at a time when the value of these securi-
ties has declined, the series may incur a loss upon disposition of them. If
the seller becomes insolvent and subject to liquidation or reorganization un-
der bankruptcy or other laws, a bankruptcy court may determine that the under-
lying securities are collateral for a loan by the series not within the con-
trol 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 acknowl-
edges 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
 
B-2
<PAGE>
 
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 five 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 in-
vestment company pays reasonable negotiated fees in connection with loaned se-
curities, so long as such fees are set forth in a written contract and ap-
proved by the investment company's Directors (Trustees). In addition, voting
rights may pass with the loaned securities, but if a material event occurs af-
fecting an investment on loan, the loan must be called and the securities vot-
ed.
 
  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 ac-
ceptance of the underlying securities, in most cases the contracts are closed
out before the settlement date without the making or taking of delivery. Clos-
ing out an open futures position is done by taking an opposite position ("buy-
ing" a contract which has previously been "sold," "selling" a contract previ-
ously purchased) in an identical contract to terminate the position. Brokerage
commissions are incurred when a futures contract is bought or sold.
 
  Futures traders are required to make a good faith margin deposit in cash or
government securities with a broker or custodian to initiate and maintain open
positions in futures contracts. A margin deposit is intended to assure comple-
tion 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. Bro-
kers 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 con-
tract 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 ex-
pects 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 unfavor-
able 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 in-
terest rates. Each series intends to use futures contracts only for bona fide
hedging purposes.
 
                                                                            B-3
<PAGE>
 
  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 se-
ries 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 con-
tracts.
 
  Although techniques other than the sale and purchase of futures contracts
could be used to control the exposure of the series' income to market fluctua-
tions, the use of futures contracts may be a more effective means of hedging
this exposure. While each series will incur commission expenses in both open-
ing 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.
 
  The risk of loss in trading futures contracts in some strategies can be sub-
stantial, 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 sub-
stantial 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 Ad-
viser does not believe that the series is subject to the risks of loss fre-
quently associated with futures transactions. The series would presumably have
sustained comparable losses if, instead of the futures contract, it had in-
vested 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
 
B-4
<PAGE>
 
position in a futures contract or related option. Additionally, investments in
futures and options involve the risk that the investment adviser will incor-
rectly 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 unfa-
vorable 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 treat-
ment 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, inter-
est, income derived from loans of securities, and gains from the sale of secu-
rities 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 antici-
pated 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 oth-
erwise 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 pur-
pose of the 30% test.
 
  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 transac-
tions). Such distributions will be combined with distributions of capital
gains realized on the series' other investments and shareholders will be ad-
vised 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 com-
puted on the date
 
                                                                            B-5
<PAGE>
 
of receipt; and an order received after the close of the Exchange will be exe-
cuted 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 of-
fering 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 for 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 pay-
ment (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 Ex-
change 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 re-
demptions 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 con-
verted 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 se-
ries' portfolio securities.
 
  SIGNATURES 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) REDEMPTIONS
INVOLVING MORE THAN $25,000 ON THE DATE OF RECEIPT BY VANGUARD OF ALL
NECESSARY DOCUMENTS; (2) 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 (3) 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 guar-
antor that Vanguard deems acceptable. NOTARIES PUBLIC ARE NOT ACCEPTABLE GUAR-
ANTORS.
 
                            YIELD AND TOTAL RETURN
 
  The yield of Vanguard/Windsor Fund for the thirty-day period ended October
31, 1994 was +3.27%, and the yield for Vanguard/Windsor II for the same period
was +3.35%.
 
 
B-6
<PAGE>
 
  The average annual total returns for Vanguard/Windsor Fund for the one-,
five- and ten-year periods ending October 31, 1994 were +6.35%, +9.23% and
+14.45%, respectively. The average annual total returns for the one- and five-
year periods, and the period since inception (6/24/85), for Vanguard/Windsor
II were +2.22%, +9.15% and +13.21%, 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 invest-
ment.
 
                            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 out-
standing 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 govern-
  ment 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 ap-
  proved by the shareholders of the series or otherwise to the extent permit-
  ted by Section 12 of the Investment Company Act of 1940. A series will in-
  vest only in investment companies which have investment objectives and in-
  vestment 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 other-
  wise require the untimely disposition of securities, in an amount not ex-
  ceeding 10% of the value of the net assets of the series (including the
  amount borrowed and the value of any outstanding reverse repurchase agree-
  ments) 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 ad-
  ditional investments;
 
    (4) purchase securities on margin, or sell securities short except that
  each series may invest in stock futures contracts, stock options and op-
  tions 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 ob-
  ligations (including repurchase agreements) which are either publicly dis-
  tributed or customarily purchased by institutional investors, and (ii) as
  provided under "Lending of Securities" (See page B-2);
 
    (9) purchase assessable securities;
 
 
                                                                            B-7
<PAGE>
 
    (10) engage in the business of underwriting securities issued by other
  persons, except to the extent that the series may technically be deemed to
  be an underwriter under the Securities Act of 1933, as amended, in dispos-
  ing of investment securities;
 
    (11) purchase real estate, commodities or commodity contracts except as
  described above in "(5)"; or
 
    (12) invest more than 25% of the value of its total assets in any one in-
  dustry.
 
  Notwithstanding these limitations, each series of the Company may own all or
any portion of the securities of, or make loans to, or contribute to the costs
or other financial requirements of any company which will be wholly owned by
the Company and one or more other investment companies and is primarily en-
gaged in the business of providing, at-cost, management, administrative or re-
lated services to the Company and other investment companies. See "Management
of the Company".
 
  These investment limitations are considered at the time investment securi-
ties are purchased.
 
  Although not fundamental policies subject to shareholder vote, as long as
the Company's shares are registered for sale in certain states, each series
may not invest in put, call, straddle or spread options (except as described
above in "(5)") or in interests in oil, gas or other mineral exploration or
development programs. In addition, each series of the Company will not invest
more than 10% of its assets, in the aggregate, determined at the time of in-
vestment, in securities subject to legal or contractual restrictions on resale
or for which there are no readily available market quotations, including re-
purchase agreements having maturities of more than 7 days.

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.
 
                                                                            B-9
<PAGE>
 
  Vanguard employs a supporting staff of management and administrative person-
nel 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, au-
diting 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 ad-
viser for the Funds.
 
  The Vanguard Group adheres to a Code of Ethics established pursuant to Rule
17j-1 under the Investment Company Act of 1940. The Code is designed to pre-
vent 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 per-
mitted to engage in personal securities transactions. However, such transac-
tions 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 have invested are adjusted from time to time
in order to maintain the proportionate relationship between each Fund's rela-
tive net assets and its contribution to Vanguard's capital. At October 31,
1994, Vanguard/Windsor Fund had contributed capital of $1,720,000 to Vanguard,
representing 8.6% of Vanguard's capitalization and, at that time,
Vanguard/Windsor II had contributed capital of $1,253,000 to Vanguard, repre-
senting 6.3% of Vanguard's capitalization. The Funds' Service Agreement was
amended on May 15, 1993, to provide as follows: (a) each Vanguard Fund may in-
vest 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 Van-
guard'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, 1994, Vanguard/Windsor Fund's share of
Vanguard's actual net costs of operation relating to management and
administrative services (including transfer agency) totaled approximately
$19,582,000 and Vanguard/Windsor II's share of such costs of operation totaled
approximately $17,200,000.
 
  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 materi-
als and marketing personnel. Distribution services may also include organizing
and offering to the public, from time to time, one or more new investment com-
panies 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 remain-
ing one half of these expenses is allocated among the Funds based upon each
Fund's sales for the preceding 24 months relative to the total sales of the
Funds as a Group, provided, however, that no Fund's aggregate quarterly rate
of contribution for distribution expenses of a marketing and promotional na-
ture shall exceed 125% of the average
 
B-10
<PAGE>
 
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, 1994, Vanguard/Windsor Fund
paid approximately $1,662,000 of the Group's distribution and marketing ex-
penses, which represented an effective annual rate of .02 of 1% of
Vanguard/Windsor Fund's average net assets and Vanguard/Windsor II paid ap-
proximately $1,481,000 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, 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 Offi-
cer'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 per-
mitted 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 serv-
ice. 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 re-
tired Director.
 
                                                                           B-11

  The following table provides detailed information with respect to the

VANGUARD/WINDSOR FUND
 
  The Company employs Wellington Management Company ("WMC") under an invest-
ment advisory agreement dated June 19, 1985 to manage the investment and rein-
vestment of the assets of Vanguard/Windsor Fund and to continuously review,
supervise and administer Vanguard/Windsor Fund's investment program. WMC dis-
charges its responsibilities subject to the control of the Officers and Direc-
tors of the Company. WMC is a Massachusetts general partnership controlled by
the following general partners: Robert W. Doran, Duncan M. McFarland and John
B. Neff.
 
  Vanguard/Windsor Fund pays WMC a basic fee at the end of each fiscal quar-
ter, 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 ad-
justment formula based on Vanguard/Windsor Fund's investment performance. Such
formula provides for an increase
 
B-12
<PAGE>
 
or decrease in the basic fee paid to WMC each quarter, depending upon
Vanguard/Windsor Fund's investment performance for the thirty-six months pre-
ceding the end of the quarter relative to the investment record of the Stan-
dard and Poor's Composite Stock Price Index (the "S&P 500") for the same peri-
od. 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 pe-
riod. 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 secu-
rities comprise the S&P Index.

VANGUARD/WINDSOR II
 
  Vanguard/Windsor II employs a "multi-manager" approach utilizing four in-
vestment advisors.
 
BARROW, HANLEY, MEWHINNEY & STRAUSS
 
  Vanguard/Windsor II has entered into an investment advisory agreement dated
May 1, 1993 with Barrow, Hanley, Mewhinney & Strauss, Inc. ("BHM&S") to manage
a portion of the assets of Vanguard/Windsor II (currently approximately 72%).
Under this agreement, BHM&S manages the investment and reinvestment of the
designated assets and continuously reviews, supervises and administers the in-
vestment program of Vanguard/Windsor II with respect to those assets. BHM&S
discharges its responsibilities subject to the control of the Officers and Di-
rectors of the Company.
 
  BHM&S is a Texas corporation controlled by the following officers of BHM&S:
James Pindy Barrow, Vice President; Bryant Miller Hanley, Jr., President;
Michael Christopher Mewhinney, Vice President and John Luke Strauss, Vice
President, Secretary and Treasurer.
 
  Vanguard/Windsor II pays BHM&S a basic fee at the end of each fiscal quar-
ter, 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:

<PAGE>
 
  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 de-
crease 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 Prospec-
tus.
 
  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 in-
  vestment performance of the BHM&S Portfolio and that of the BARRA Value In-
  dex 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 ex-
  ceed or fall below that of the BARRA Value Index will increase proportion-
  ately from 3 percentage points and 2 percentage points, respectively, for
  the twelve months ended April 30, 1994 to 9 percentage points and 6 per-
  centage points, respectively for the thirty-six months ended April 30,
  1996.
 
  The BARRA Value Index includes stocks in the Standard and Poor's 500 Compos-
ite 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 ex-
pressed 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-div-
idend 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 un-
distributed realized long-term capital gains realized from the BHM&S Portfo-
lio.
 
  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, 1992, 1993 and 1994,
Vanguard/Windsor II paid advisory fees to BHM&S of approximately $4,572,000,
$6,488,000 and $7,518,000, respectively.     
 
  OTHER ADVISERS. On November 1, 1991, Vanguard/Windsor II added Equinox Capi-
tal Management ("Equinox") and Tukman Capital Management ("Tukman") to manage
the investment and reinvestment of a portion of its assets (approximately 10%
each). Additionally, Vanguard's Core Manage-

ment Group was added to manage approximately 8% of the Vanguard/Windsor II's
assets as of that date. Equinox, Tukman and Vanguard's Core Management Group
discharge their respective responsibilities subject to the control of the Di-
rectors and Officers of the Fund.
 
EQUINOX
 
  Equinox is a Delaware corporation controlled by the following officers of
Equinox: Ronald J. Ulrich (Director and President), Edward E. Murphy (Princi-
pal), Wendy D. Lee (Managing Director), David E. Walker (Vice President) and
Laura Starr (Vice President).
 
  Under the terms of an investment advisory agreement dated November 1, 1991,
Vanguard/Windsor II pays Equinox a basic fee at the end of each fiscal quar-
ter, calculated by applying a quarterly rate, based on the following annual
percentage rates, to the portion of Vanguard/Windsor II's average month-end
net assets managed by Equinox for the quarter.

  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") rel-
ative 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 Portfo-
lio'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 ex-
pressed 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 in-
vestment 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 real-
ized 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 num-
ber 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, 1992, 1993 and 1994,
Vanguard/Windsor II paid advisory fees to Equinox of approximately $781,000,
$1,171,000 and $1,424,000, 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:

tive 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

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, 1992, 1993 and 1994,
Vanguard/Windsor II paid advisory fees to Tukman of approximately $1,028,000,
$1,503,000 and $1,825,000, respectively.
 
VANGUARD'S CORE MANAGEMENT GROUP
 
  Since November 1, 1991, Vanguard's Core Management Group has provided in-
vestment advisory services on an at-cost basis with respect to a portion of
the Vanguard/Windsor II's assets (currently
 
B-16
<PAGE>
 
approximately 8%). The Core Management Group also provides investment advisory
services to several Vanguard Funds, including Vanguard Index Trust, Vanguard
Balanced Index Fund, Vanguard International Equity Index Fund, Vanguard Insti-
tutional Index Fund, several indexed separate accounts as well as a portion of
Vanguard/Morgan Growth Fund's assets. The quantitative approach used by Van-
guard'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 us-
ing an optimizer to assure that the characteristics of the portfolio are simi-
lar 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, 1995. Vanguard/Windsor II's present agreements with BHM&S, Equinox and
Tukman continue in effect until April 30, 1995, October 31,1995 and October
31, 1995, 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 sharehold-
ers. 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.
 
  Each investment advisory agreement is automatically terminated if assigned,
and may be terminated without penalty at any time (1) by majority vote of ei-
ther 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 no-
tice 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 ad-
    viser 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 advi-
    sory 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 no-
tice to shareholders, which shall include the information concerning the ad-
viser 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 di-
rectors 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 insig-
nificant 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 perfor-
mance difference exist before the maximum fee
 
                                                                           B-17
<PAGE>
 
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 sig-
nificant." The Board of Directors has fully considered the SEC Release and be-
lieves that the performance adjustments as included in the agreements with WMC,
BHM&S, Equinox and Tukman are entirely appropriate although not within the plus
or minus 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 plus or minus 12 and plus or minus 9 percentage
points from the performance of the respective index over a thirty-six month
period, which would effectively be the equivalent of approximately plus or
minus 4 and plus or minus 3 percentage points difference per year.
 
                            PORTFOLIO TRANSACTIONS
 
  WMC, BHM&S, Equinox, Tukman and Vanguard are authorized to (with the ap-
proval of the Board of Directors) select the brokers or dealers that will exe-
cute 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 exe-
cution as to all transactions. Each investment adviser has undertaken to exe-
cute each investment transaction at a price and commission which provides the
most favorable total cost or proceeds reasonably obtainable under the circum-
stances.
 
  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 deter-
mined that more than one broker can offer the brokerage services needed to ob-
tain the best available price and most favorable execution, consideration may
be given to those brokers which supply investment research and statistical in-
formation and provide other services in addition to execution services to the
series and/or the investment adviser. Each investment adviser 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 se-
ries 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 re-
sponsibilities 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 neces-
sary for the achievement of better execution of certain securities transac-
tions 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 transac-
tions 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 ob-
taining 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
 
B-18
<PAGE>
 
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 par-
ticular 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, 1992, 1993 and 1994 the Company
paid $11,073,668, $14,909,648 and $14,906,748 in brokerage commissions, re-
spectively.
 
  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 ad-
viser.
 
                             PERFORMANCE MEASURES

                    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 Incor-
poration permit the Directors to issue 1,600,000,000 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
 
B-20
<PAGE>
 
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 fea-
tures. 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 Direc-
tors 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 aggre-
gate 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.
