YIELD AND TOTAL
RETURN                From time to time the Portfolio may advertise its yield
                      and total return. Both yield and total return figures are
                      based on historical earnings and are not intended to
                      indicate future performance. The "total return" of the
                      Portfolio refers to the average annual compounded rates of
                      return over one-, five- and ten-year periods or for the
                      life of the Portfolio (as stated in the advertisement)
                      that would equate an initial amount invested at the
                      beginning of a stated period to the ending redeemable
                      value of the investment, assuming the reinvestment of all
                      dividend and capital gains distributions.
 
   
                      In accordance with industry guidelines set forth by the
                      U.S. Securities and Exchange Commission, the "thirty-day
                      yield" of the Portfolio is calculated by dividing net
                      investment income per share earned during a thirty-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 Portfolio's securities and
                      is net of all expenses and all recurring and nonrecurring
                      charges that have been applied to all shareholder
                      accounts. The yield calculation assumes that 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 Portfolio to
                      maintain its books and records, and so the advertised
                      thirty-day yield may not fully reflect the income paid to
                      an investor's account.

INVESTMENT
OBJECTIVE

THE PORTFOLIO SEEKS
TO PROVIDE LONG-TERM
CAPITAL GROWTH        The Portfolio invests primarily in equity securities of
                      companies based in the United States. The objective of the
                      Portfolio is to provide long-term capital appreciation.
                      Dividend income is expected to be incidental to this
                      objective. There is no assurance that the Portfolio will
                      achieve its objective.
 
                      The investment objective of the Portfolio is fundamental,
                      and so cannot be changed without the approval of a
                      majority of the Portfolio's shareholders.

INVESTMENT
POLICIES

THE PORTFOLIO
EMPHASIZES STOCKS
WITH ABOVE-
AVERAGE GROWTH
POTENTIAL             The Portfolio invests chiefly in equity securities,
                      including common stocks and securities convertible into
                      common stocks, which offer favorable prospects for capital
                      growth but little current income. The Portfolio is managed
                      without regard to tax ramifications.
 
                      The Portfolio invests primarily in equity securities of
                      seasoned U.S. companies with above-average prospects for
                      growth. In selecting securities for the Portfolio, Lincoln
                      Capital Management, adviser to the Portfolio, emphasizes
                      common stocks of high-quality, established-growth
                      companies. Such companies tend to have exceptional growth
                      records, strong market positions, reasonable financial
                      strength, and relatively low sensitivity to changing
                      economic conditions. The adviser seeks to identify common
                      stocks that sell at attractive valuations and companies
                      that have the best prospects for continued above-average
                      growth.
 
                      Besides investing in equity securities, the Portfolio may
                      utilize stock index futures contracts and options to a
                      limited extent. In addition, although the Portfolio will
                      normally remain fully invested in equity securities, the
                      Portfolio may temporarily invest in certain short-term
                      fixed income securities. See "Implementation of Policies"
                      for a description of these and other investment practices
                      of the Portfolio.

                      The Portfolio is responsible for voting the shares of all
                      securities it holds.
    
 
                      The investment policies described above are not
                      fundamental policies and therefore may be changed by the
                      Board of Directors without shareholder approval. However,
                      shareholders would be notified prior to any material
                      change in the Portfolio's policies.

INVESTMENT RISKS      As a mutual fund investing in equity securities, the
                      Portfolio is subject to market risk -- i.e., the
THE PORTFOLIO IS      possibility that stock prices in general will decline over
SUBJECT TO STOCK      short or even extended periods. Stock markets tend to be
MARKET RISK           cyclical, with periods when stock prices generally rise
                      and periods when stock prices generally decline.
 
   
                      To illustrate the volatility of stock prices, the
                      following table sets forth the extremes for U.S. stock
                      market returns as well as the average return for the
                      period from 1926 to 1994, as measured by the Standard &

</TABLE>
    
 
                      As shown, stocks have provided an average annual total
                      return (capital appreciation plus dividend income) for 10
                      years, of +10.6%. Average return may not be useful for
                      forecasting future returns in any particular period, as
                      stock returns are quite volatile from year to year.
 
                      This table on U.S. stock market returns should not be
                      viewed as a representation of future returns from U.S.
                      stock markets or the Portfolio. The illustrated returns
                      represent the historical performance of unmanaged
                      portfolios of securities (before subtracting portfolio
                      transaction costs and other expenses of an investment
                      portfolio), which may be a poor guide to future returns.
                      In addition, the Portfolio is likely to differ in terms of
                      portfolio composition from these particular indices, and
                      so the performance of the Portfolio should not be expected
                      to mirror the return provided by a specific index.
 
THE PORTFOLIO         The investment adviser manages the Portfolio according to
IS SUBJECT TO         the traditional methods of "active" investment management,
MANAGER RISK          which involve the buying and selling of securities based
                      upon economic, financial and market analysis and
                      investment judgment. Manager risk refers to the
                      possibility that the Portfolio's investment adviser may
                      fail to effectively execute the Portfolio's investment
                      strategy. As a result, the Portfolio may fail to achieve
                      its stated objective.

                      fluctuations in the value of their investment. Investors
                      who engage in excessive account activity generate
                      additional costs which are borne by all the Portfolio's
                      shareholders. In order to minimize such costs, the
                      Portfolio has adopted the following policies. The
                      Portfolio 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 Portfolio has adopted
                      exchange privilege limitations as described in the section
                      "Exchange Privilege Limitations." Finally, the Portfolio
                      reserves the right to suspend the offering of its shares.
 
                      Because of these risks, the Portfolio should not be
                      considered 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 wish to
                      purchase shares on a regular, periodic basis (dollar-cost
                      averaging), rather than investing in one lump sum in order
                      to reduce the risk of investing all their monies in common
                      stocks at a particularly unfavorable time. Investors may
                      also wish to complement an investment in the Portfolio
                      with other types of common stock investments.
- --------------------------------------------------------------------------------
 
IMPLEMENTATION
OF POLICIES           In addition to investing in growth-oriented common stocks,
                      the Portfolio follows a number of additional investment
                      practices to achieve its objective.
 
   
THE PORTFOLIO MAY
INVEST IN SHORT-TERM
FIXED INCOME
SECURITIES            Although the Portfolio normally seeks to remain fully
                      invested in equity securities, the Portfolio may invest
                      temporarily in certain short-term fixed income securities.
                      Such securities may be used to invest uncommitted cash
                      balances, to maintain liquidity to meet shareholder
                      redemptions, or to take a temporary defensive position
                      against potential stock market declines. These securities
                      include: obligations of the United States Government and
                      its agencies or instrumentalities; commercial paper, bank
                      certificates of deposit, and bankers' acceptances; and
                      repurchase agreements collateralized by these securities.
    
 
   
THE PORTFOLIO MAY
LEND ITS SECURITIES   The Portfolio may lend its investment securities to
                      qualified institutional investors for either short-term or
                      long-term purposes of realizing additional net investment
                      income. Loans of securities by the Portfolio will be
                      collateralized by cash, letters of credit, or securities
                      issued or guaranteed by the U.S. Government or its
                      agencies or instrumentalities. The collateral will equal
                      at least 100% of the current market value of the loaned
                      securities.
    
 
   
PORTFOLIO TURNOVER IS
NOT EXPECTED TO
EXCEED 100%           Although it generally seeks to invest for the long term,
                      the Portfolio retains the right to sell securities
                      irrespective of how long they have been held. It is
                      anticipated that the annual turnover rate of the Portfolio
                      will not exceed 100%. A turnover rate of 100% would occur,
                      for example, if all of the securities of the Portfolio
                      were replaced within a one-year period.
    
 
   
DERIVATIVE
INVESTING
                      Derivatives are instruments whose values are linked to or
                      derived from an underlying security or index. The most
                      common and conventional types of derivative securities are
                      futures and options.

THE PORTFOLIO MAY
INVEST IN DERIVATIVE
SECURITIES
                      The Portfolio may invest in futures contracts and options,
                      but only to a limited extent. Specifically, a Portfolio of
                      the Fund may enter into futures contracts provided that
                      not more than 5% of its assets are required as a futures
                      contract deposit; in addition, a Portfolio 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
                      Portfolio's assets.
    
 
   
                      Futures contracts and options may be used for several
                      common fund management strategies: to maintain cash
                      reserves while simulating full investment, to facilitate
                      trading, to reduce transaction costs, or to seek higher
                      investment returns when a specific futures contract is
                      priced more attractively than other futures contracts or
                      the underlying security or index.
    
 
   
FUTURES AND OPTIONS
POSE CERTAIN RISKS    The primary risks associated with the use of futures
                      contracts and options are: (i) imperfect correlation
                      between the change in market value of the stocks held by a
                      Portfolio and the prices of futures 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 Portfolio's underlying securities. The risk that the
                      Portfolio will be unable to close out a futures position
                      will be minimized by entering into such transactions on a
                      national exchange with an active and liquid secondary
                      market.
    
 
                      The risk of loss in trading futures contracts in some
                      strategies can be substantial, due both to the low margin
                      deposits required and the extremely high degree of
                      leverage involved in futures pricing. As a result, a
                      relatively small price movement in a futures contract may
                      result in immediate and substantial loss (or gain) to the
                      investor. When investing in futures contracts, the
                      Portfolio will segregate cash or cash equivalents in the
                      amount of the underlying obligation.

INVESTMENT
LIMITATIONS

THE PORTFOLIO HAS
ADOPTED CERTAIN
FUNDAMENTAL
LIMITATIONS           The Portfolio has adopted certain limitations on its
                      investment practices. Specifically, the Portfolio will
                      not:
 
                      (a)   with respect to 75% of its assets, invest more than
                            5% of its assets in the securities of any single
                            company, excluding obligations of the U.S.
                            government;
 
                      (b)   with respect to 75% of its assets, purchase more
                            than 10% of the outstanding voting securities of any
                            issuer;
 
                      (c)   invest more than 5% of its assets in the securities
                            of companies that have a continuous operating
                            history of less than 3 years;
 
                      (d)   invest more than 25% of its assets in any one
                            industry;
 
                      (e)   borrow money, except from a bank and only for
                            temporary or emergency purposes to facilitate the
                            meeting of redemption requests (not for leverage);
                            and
 
                      (f)   pledge, mortgage or hypothecate assets to an extent
                            greater than 15% of the value of its gross assets.

                      These investment limitations are considered at the time
                      investment securities are purchased. The limitations
                      described here and in the Statement of Additional
                      Information are fundamental and so may be changed only
                      with the approval of a majority of the Portfolio's
                      shareholders.

MANAGEMENT OF
THE PORTFOLIO

VANGUARD ADMINISTERS
AND DISTRIBUTES THE
PORTFOLIO             The Fund is a member of The Vanguard Group of Investment
                      Companies, a family of more than 30 investment companies
                      with more than 90 distinct investment portfolios and total
                      assets in excess of $170 billion. Through its
                      jointly-owned subsidiary, The Vanguard Group, Inc.
                      ("Vanguard"), the Fund and the other funds in the Group
                      obtain at cost virtually all of their corporate
                      management, administrative and distribution services.
                      Vanguard also provides investment advisory services on an
                      at-cost basis to certain Vanguard funds. As a result of
                      Vanguard's unique corporate structure, the Vanguard funds
                      have costs substantially lower than those of most mutual
                      funds. In 1994, the average expense ratio (annual costs
                      including advisory fees divided by average 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
                      Directors set broad policies for the Fund and choose its
                      Officers. A list of the Directors and Officers of the Fund
                      and a statement of their present positions and principal
                      occupations during the past five years can be found in the
                      Statement of Additional Information.
 
                      Vanguard employs a supporting staff of management and
                      administrative personnel needed to provide the requisite
                      services to the funds and also furnishes the funds with
                      necessary office space, furnishings and equipment. Each
                      fund pays its share of Vanguard's total expenses, which
                      are allocated among the funds under methods approved by
                      the Board of Directors (Trustees) of each fund. In
                      addition, each fund bears its own direct expenses, such as
                      legal, auditing and custodian fees.
 
                      Vanguard provides distribution and marketing services to
                      the funds. The funds are available on a no-load basis,
                      (i.e., there are no sales commissions or 12b-1 fees).
                      However, each fund bears its allocated share of the
                      Group's distribution costs.

INVESTMENT
ADVISER

LINCOLN CAPITAL
MANAGEMENT SERVES
AS ADVISER TO THE
PORTFOLIO             The Portfolio employs Lincoln Capital Management Company
                      ("Lincoln"), 200 South Wacker Drive, Chicago, IL 60606 as
                      the adviser to the Portfolio. The adviser discharges its
                      responsibilities subject to the control of the Officers
                      and Directors of the Fund.
    
 
   
                      Lincoln, an investment advisory firm founded in 1967,
                      currently provides investment counseling services to a
                      limited number of clients, most of which are institutional
                      clients, such as pension funds. Currently, Lincoln holds
                      discretionary management authority with respect to
                      approximately $33 billion in assets.
    
 
                      Lincoln employs a team of investment professionals who
                      participate in investment strategy formulation and issue
                      selection. Client equity portfolios are highly similar in
                      terms of their stock composition. The individuals
                      responsible for overseeing the
 
                                        8
<PAGE>   11
 
                      implementation of Lincoln's strategy for the Portfolio,
                      who have served in this capacity since Lincoln became the
                      Portfolio's adviser in August 1987, are J. Parker Hall
                      III, President of Lincoln, and David M. Fowler, Vice
                      President of Lincoln.
 
   
                      The Portfolio pays Lincoln an advisory fee calculated by
                      applying varying percentage rates to the average month-end
                      net assets of the Portfolio. The maximum rate is .40% on
                      the first $25 million of net assets. The rate decreases to
                      .35% on the next $125 million of net assets, to .25% on
                      the next $350 million of net assets, to .20% on the next
                      $500 million of net assets, .15% on the next $1.5 billion
                      of assets and .10% on assets in excess of $2.5 billion.
                      The agreement does not provide for an incentive
                      fee/penalty based on performance. For the year ended
                      August 31, 1995, the investment advisory fee paid to
                      Lincoln, represented an effective annual rate of .19 of 1%
                      of the Portfolio's average net assets.
    
 
                      The investment advisory agreement with Lincoln authorizes
                      the adviser to select brokers or dealers to execute
                      purchases and sales of the Portfolio's 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 Portfolio has authorized Lincoln to pay higher
                      commissions in recognition of brokerage services felt
                      necessary for the achievement of better execution,
                      provided the investment adviser believes this to be in the
                      best interest of the Portfolio. Although the Portfolio
                      does not market its shares through intermediary brokers or
                      dealers, the Portfolio may place orders for the Portfolio
                      with qualified broker-dealers who recommend the Portfolio
                      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 Board of Directors may, without the approval of
                      shareholders, provide for: (a) the employment of a new
                      investment adviser pursuant to the terms of a new advisory
                      agreement either as a replacement for an existing adviser
                      or as an additional adviser; (b) a change in the terms of
                      an advisory agreement; and (c) the continued employment of
                      an existing adviser on the same advisory contract terms
                      where a contract has been assigned because of a change in
                      control of the adviser. Any such change will only be made
                      upon not less than 30 days prior written notice to
                      shareholders of the Portfolio which shall include
                      substantially the information concerning the adviser that
                      would have normally been included in a proxy statement.

                      Portfolio. The results shown represent "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 unmanaged Standard & Poor's 500 Composite
                      Index, a widely-used barometer of stock market activity;
                      and the Consumer Price Index, a statistical measurement 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 Portfolio
                      today. The periods shown were generally favorable ones for
                      stock market investing. This information is provided to
                      help you better understand the Portfolio and may not
                      provide a basis for comparison with other investments or
                      mutual funds which use a different method to calculate
                      performance. In weighing these performance figures, you
                      should note that the Portfolio was managed by a different
                      adviser through August 31, 1987.

DIVIDENDS,
CAPITAL GAINS
AND TAXES

THE PORTFOLIO PAYS
DIVIDENDS AND ANY
CAPITAL GAINS
ANNUALLY              Dividends consisting of virtually all of the ordinary
                      income of the Portfolio are declared and paid to
                      shareholders annually. Capital gains distributions, if
                      any, will also be made annually. Dividend and capital
                      gains distributions may be automatically reinvested or
                      received in cash. See "Choosing a Distribution Option" for
                      a description of these distribution methods.
 
                      In order to satisfy certain distribution requirements of
                      the Tax Reform Act of 1986, the Portfolio may declare
                      special year-end dividend and capital gains distributions
                      during December. Such distributions, if received by
                      shareholders by January 31, are deemed to have been paid
                      by the Portfolio and received by shareholders on December
                      31 of the prior year.
 
                      The Portfolio intends to continue to qualify for taxation
                      as a "regulated investment company" under the Internal
                      Revenue Code so that it will not be subject to federal
                      income tax to the extent its income is distributed to
                      shareholders. Dividends paid by the Portfolio from net
                      investment income, whether received in cash or reinvested
                      in additional shares, will be taxable to shareholders as
                      ordinary income. For corporate investors, dividends from
                      net investment income will generally qualify in part for
                      the intercorporate dividends-received deduction. However,
                      the portion of the dividends so qualified depends on the
                      aggregate taxable qualifying dividend income received by
                      the Portfolio from domestic (U.S.) sources.
 
   
                      Distributions paid by the Portfolio from long-term capital
                      gains, whether received in cash or reinvested in
                      additional shares, are taxable, regardless of the length
                      of time you have owned shares in the Portfolio. Capital
                      gains distributions are made when the Portfolio realizes
                      net capital gains on sales of portfolio securities during
                      the year. The Portfolio does not seek to realize any
                      particular amount of capital gains during a year; rather,
                      realized gains are a by-product of portfolio management
    
 
                                       10
<PAGE>   13
 
                      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
                      Portfolio realizes net capital losses.
 
                      Note that if you elect to receive 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 Portfolio. Also, keep in mind that
                      if you purchase shares in the Portfolio shortly before the
                      record date for a dividend or capital gains distribution,
                      a portion of your investment will be returned to you as a
                      taxable distribution, regardless of whether you are
                      reinvesting your distributions or receiving them in cash.
 
                      The Portfolio will notify you annually as to the tax
                      status of dividend and capital gains distributions paid by
                      the Portfolio.
 
A CAPITAL GAIN OR     A sale of shares of the Portfolio is a taxable event, and
LOSS MAY BE           may result in a capital gain or loss. A capital gain or
REALIZED UPON         loss may be realized from an ordinary redemption of shares
EXCHANGE OR           or an exchange of shares between two mutual funds (or two
REDEMPTION            portfolios of a mutual fund).
                      
                      Dividend distributions, capital gains distributions and
                      capital gains or losses from redemptions and exchanges may
                      be subject to state and local taxes.
 
                      The Portfolio is required to withhold 31% of taxable
                      dividends, capital gains distributions, and redemptions
                      paid to shareholders who have not complied with IRS
                      taxpayer identification regulations. You may avoid this
                      withholding requirement by certifying on your account
                      registration form your proper Social Security or Employer
                      Identification number and certifying that you are not
                      subject to backup withholding.
 
                      The Fund has obtained a Certificate of Authority to do
                      business as a foreign corporation in Pennsylvania, and
                      does business and maintains an office in that state. In
                      the opinion of counsel, the shares of the Portfolio are
                      exempt from Pennsylvania personal property taxes.
 
                      The tax discussion set forth above is included for general
                      information only. Prospective investors should consult
                      their own tax advisers concerning the tax consequences of
                      an investment in the Portfolio.
- --------------------------------------------------------------------------------
 
   
THE SHARE PRICE       The Portfolio's share price or "net asset value" is
OF THE                calculated each business day after the close of regular
PORTFOLIO             trading (generally 4:00 p.m. Eastern time) of the New York
                      Stock Exchange. Net asset value per share is computed by
                      adding up the total value of the Portfolio's investments
                      and other assets, subtracting any of its liabilities, or
                      debts, and then dividing by the number of outstanding
                      shares of the Portfolio.
    
 
   
                      Securities listed on a U.S. exchange are valued at the
                      latest quoted sale price on the day the valuation is made.
                      Securities listed on a U.S. exchange not traded on the
                      valuation date are valued at the mean of the bid and ask
                      prices. If events which materially affect the value of a
                      Portfolio's investments occur after the close of the
                      securities markets on which such securities are primarily
                      traded, those investments will be priced at "fair value".
                      All prices of listed securities are taken from the
                      exchange where the security is primarily traded.
                      Securities regularly traded in the over-the-counter market
                      for which market quotations are readily available will be
                      valued at the latest quoted bid price.

                      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. Other
                      assets and securities for which no quotations are readily
                      available will be valued in a manner determined in good
                      faith by the Board of Directors.
 
   
                      The Portfolio's share price can be found daily in the
                      mutual fund listings of most major newspapers under the
                      heading of Vanguard.

GENERAL               The Fund was organized as Ivest Fund, a Massachusetts
INFORMATION           Corporation, in 1959. The Fund is now a Maryland
                      Corporation and is authorized to issue 550,000,000 shares
                      with a par value of $1.00 per share. Currently, the Fund
                      is offering shares of two Portfolios with 250,000,000
                      shares allocated to the U.S. Growth Portfolio and
                      300,000,000 shares allocated to the International Growth
                      Portfolio.
    
 
                      The shares of each Portfolio are fully paid and
                      non-assessable; have no preference as to conversion,
                      exchange, dividends, retirement or other features; and
                      have no pre-emptive rights. The shares of each Portfolio
                      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.
 
                      The Fund will not hold annual meetings of shareholders
                      except as required by the Investment Company Act of 1940
                      and other applicable law. The Directors of the Fund will
                      call a meeting of shareholders for the purpose of voting
                      upon the question of removal of a Director or Directors if
                      such a meeting is requested in writing by the holders of
                      not less than 10% of the outstanding shares of the Fund.
 
                      All securities and cash of the Portfolio are held by State
                      Street Bank and Trust Company, Boston, MA. The Vanguard
                      Group, Inc. Valley Forge, PA, serves as the Portfolio's
                      Transfer and Dividend Disbursing Agent. Price Waterhouse
                      LLP, serves as independent accountants for the Fund and
                      will audit its financial statements annually. The Fund is
                      not involved in any litigation.

OPENING AN
ACCOUNT AND
PURCHASING
SHARES                You may open a regular (non-retirement) account, either by
                      mail or wire. Simply complete and return an Account
                      Registration Form and any required legal documentation,
                      indicating the amount you wish to invest. Your purchase
                      must be equal to or greater than the $3,000 minimum
                      initial investment requirement ($1,000 for Uniform
                      Gifts/Transfers to Minors Act accounts). You must open a
                      new Individual Retirement Account by mail (IRA's may not
                      be opened by wire) using a Vanguard IRA Adoption
                      Agreement. Your purchase must be equal to or greater than
                      the $1,000 minimum initial investment requirement, but no
                      more than $2,000 if you are making a regular IRA
                      contribution. Rollover contributions are generally limited
                      to the amount withdrawn within the past 60 days from an
                      IRA or other qualified Retirement Plan. If you need
                      assistance with the forms or have any questions about the
                      Portfolio, please call our Investor Information Department
                      at 1-800-662-7447. Note: For other types of account
                      registrations (e.g., corporations, associations, other
                      organizations, trust or powers of attorney), please call
                      our Investor Information Department to determine which
                      additional forms you may need.
    
 
   
                      The Portfolio's shares are purchased at the
                      next-determined net asset value after your investment has
                      been received. The Portfolio is offered on a no-load basis
                      (i.e., there are no sales commissions or 12b-1 fees).
    
 
   
PURCHASE
RESTRICTIONS          1) Because of the risks associated with common stock
                         investments, the Portfolio is intended to be a
                         long-term investment vehicle and is not designed to
                         provide investors with a means of speculating on
                         short-term market movements. Consequently, the
                         Portfolio reserves the right to reject any specific
                         purchase (and exchange purchase) request. The Portfolio
                         also reserves the right to suspend the offering of
                         shares for a period of time.
    
 
   
                      2) Vanguard will not accept third-party checks to purchase
                         shares of the Fund. Please be sure your purchase check
                         is made payable to the Vanguard Group.
    
 
   
ADDITIONAL
INVESTMENTS           Subsequent investments to regular accounts may be made by
                      mail ($100 minimum), wire ($1,000 minimum), exchange from
                      another Vanguard Fund account, or Vanguard Fund Express.
                      Subsequent investments to Individual Retirement Accounts

                         capital gains distributions will be reinvested in

                      3. ALL CASH OPTION -- Both dividend and capital gains
                         distributions will be paid in cash.

                      Department (1-800-662-2739).
 
                      In addition, an option to invest your cash dividends
                      and/or capital gains distributions in another Vanguard
                      Fund account is available. Please call our Client Services
                      Department (1-800-662-2739) for information. You may also
                      elect Vanguard Dividend Express which allows you to
                      transfer your cash dividends and/or capital gains
                      distributions automatically to your bank account. Please

TAX CAUTION

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

SIGNATURE GUARANTEES  For our mutual protection, we may require a signature
                      guarantee on certain written transaction requests. A
                      signature guarantee verifies the authenticity of your
                      signature, and may be obtained from banks, brokers and any
                      other guarantor that Vanguard deems acceptable. A
                      SIGNATURE GUARANTEE CANNOT BE PROVIDED BY A NOTARY PUBLIC.
 
CERTIFICATES          Share certificates will be issued upon request. If a
                      certificate is lost, you may incur an expense to replace
                      it.
 
   
BROKER-DEALER
PURCHASES             If you purchase shares in Vanguard Funds through a
                      registered broker-dealer or investment adviser, the
                      broker-dealer or investment adviser may charge a service
                      fee.
    
 
CANCELLING TRADES     The Portfolio will not cancel any trade (e.g., purchase,
                      redemption or exchange) believed to be authentic,
                      received in writing or by telephone, once the trade
                      request has been received.

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

                      (generally, 4:00 p.m. Eastern time) are processed on the
                      day of receipt and the redemption proceeds are normally
                      sent on the following business day.
 
                      Redemption requests received by telephone after the close
                      of the Exchange are processed on the business day
                      following receipt and the proceeds are normally sent on
                      the second business day following receipt. Redemption
                      proceeds must be sent to you within seven days of receipt
                      of your request in Good Order.
 
                      If you experience difficulty in making a telephone
                      redemption during periods of drastic economic or market
                      changes, your redemption request may be made by regular or
 
                                       17

                      express mail. It will be implemented at the net asset
                      value next determined after your request has been received
                      by Vanguard in Good Order. The Portfolio reserves the
                      right to revise or terminate the telephone redemption
                      privilege at any time.
 
                      The Portfolio may suspend the redemption right or postpone
                      payment at times when the New York Stock Exchange is
                      closed, or under any emergency circumstances as determined
                      by the United States Securities and Exchange Commission.
 
                      If the Board of Directors determines that it would be
                      detrimental to the best interests of the Portfolio's
                      remaining shareholders to make payment in cash, the
                      Portfolio may pay the redemption proceeds in whole or in
                      part by a distribution in kind of readily marketable
                      securities.

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

IMPORTANT EXCHANGE
INFORMATION           Before you make an exchange, you should consider the
                      following:
 
                      -  Please read the Portfolio's prospectus before making an
                         exchange. For a copy and for answers to any questions
                         you may have, call our Investor Information Department
                         (1-800-662-7447).
 
                      -  An exchange is treated as a redemption and a purchase.
                         Therefore, you could realize a taxable gain or loss on
                         the transaction.
 
                      -  Exchanges are accepted only if the registrations and
                         the Taxpayer Identification numbers of the two accounts
                         are identical.
 
                      -  The shares to be exchanged must be on deposit and not
                         held in certificate form.
 
   
                      -  New accounts are not currently accepted in
                         Vanguard/Windsor Fund or Vanguard/PRIMECAP Fund.
    
 
                      -  The redemption price of shares redeemed by exchange is
                         the net asset value next determined after Vanguard has
                         received the required documentation 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 Portfolio reserves the right to
                      revise or terminate its provisions, limit the amount of or
                      reject any exchange, as deemed necessary, at any time.
 
                      The exchange privilege is only available in states in
                      which the shares of the Portfolio are registered for sale.
                      The Portfolio's shares are currently registered for sale
                      in all 50 states and the Portfolio intends to maintain
                      such registration.

EXCHANGE
PRIVILEGE
LIMITATIONS           The Portfolio's exchange privilege is not intended to
                      afford shareholders a way to speculate on short-term
                      movements in the market. Accordingly, in order to prevent
                      excessive use of the exchange privilege that may
                      potentially disrupt the management of the Portfolio and
                      increase transactions costs, the Portfolio has established
                      a policy of limiting excessive exchange activity.
 
   
                      Exchange activity generally will not be deemed excessive
                      if limited to TWO SUBSTANTIVE EXCHANGE REDEMPTIONS (AT
                      LEAST 30 DAYS APART) from the Portfolio during any
                      twelve-month period. Notwithstanding these limitations,
                      the Portfolio reserves the right to reject any purchase
                      request (including exchange purchases from other Vanguard
                      portfolios) that is reasonably deemed to be disruptive to
                      efficient portfolio management.

IMPORTANT
INFORMATION ABOUT
TELEPHONE
TRANSACTIONS          The ability to initiate redemptions (except wire
                      redemptions) and exchanges by telephone is automatically
                      established on your account unless you request in writing
                      that telephone transactions on your account not be
                      permitted.
 
                      To protect your account from losses resulting from
                      unauthorized or fraudulent telephone instructions,
                      Vanguard adheres to the following security procedures:
 
                      1. SECURITY CHECK.  To request a transaction by telephone,
                         the caller must know (i) the name of the Portfolio;
                         (ii) the 10-digit account number; (iii) the exact name
                         and address used in the registration; and (iv) the
                         Social Security or Employer Identification number
                         listed on the account.
 
                      2. PAYMENT POLICY.  The proceeds of any telephone
                         redemption made by mail will be made payable to the
                         registered shareowner and mailed to the address of
                         record, only.
 
                      Neither the Portfolio nor Vanguard will be responsible for
                      the authenticity of transaction instructions received by
                      telephone, provided that reasonable security procedures
                      have been followed. Vanguard believes that the security
                      procedures described above are reasonable and that if such
                      procedures are followed, you will bear the risk of any
                      losses resulting from unauthorized or fraudulent telephone
                      transactions on your account. If Vanguard fails to follow
                      reasonable security procedures, it may be liable for any
                      losses resulting from unauthorized or fraudulent telephone
                      transactions on your account.

STATEMENTS
AND REPORTS           Vanguard will send you a confirmation statement each time
                      you initiate a transaction in your account (except for
                      checkwriting redemptions from Vanguard money market
                      accounts). You will also receive a comprehensive account
                      statement at the end of each calendar quarter. The
                      fourth-quarter statement will be a year-end statement,
                      listing all transaction activity for the entire calendar
                      year.

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

INVESTMENT            The Portfolio invests primarily in equity securities of
OBJECTIVE             companies based in the United States. The objective of the
                      Portfolio is to provide long-term capital appreciation.
THE PORTFOLIO SEEKS   Dividend income is expected to be incidental to this
TO PROVIDE LONG-TERM  objective. There is no assurance that the Portfolio will
CAPITAL GROWTH        achieve its objective.
 
                      The investment objective of the Portfolio is fundamental,
                      and so cannot be changed without the approval of a
                      majority of its shareholders.
- --------------------------------------------------------------------------------
 
   
INVESTMENT            The Portfolio invests primarily in equity securities of
POLICIES              seasoned U.S. companies with above-average prospects for
                      growth. In selecting securities for the Portfolio, Lincoln
THE PORTFOLIO         Capital Management, adviser to the Portfolio, emphasizes
EMPHASIZES U.S.       common stocks of high-quality, established-growth
STOCKS WITH ABOVE-    companies. Such companies tend to have exceptional growth
AVERAGE GROWTH        records, strong market positions, reasonable financial
POTENTIAL             strength, and relatively low sensitivity to changing
                      economic conditions. The adviser seeks to identify common
                      stocks that sell at attractive valuations and companies
                      that have the best prospects for continued above-average
                      growth. The Portfolio is managed without regard to tax
                      ramifications.
    
 
                      Besides investing in equity securities, the Portfolio may
                      utilize stock index futures contracts and options to a
                      limited extent. In addition, although the Portfolio will
                      normally remain fully invested in equity securities, it
                      may temporarily invest in certain short-term fixed income
                      securities. See "Implementation of Policies" for a
                      description of these and other investment practices of the
                      Portfolio.
 
   
                      The Portfolio is responsible for voting the shares of all
                      securities it holds.

                      The investment policies described above are not
                      fundamental policies and therefore may be changed by the
                      Board of Directors without shareholder approval. However,
                      shareholders would be notified prior to any material
                      change in the Portfolio policies.

INVESTMENT RISKS      As a mutual fund investing in equity securities, the
                      Portfolio is subject to market risk -- i.e., the
THE PORTFOLIO IS      possibility that stock prices in general will decline over
SUBJECT TO STOCK      short or even extended periods. Stock markets tend to be
MARKET RISK           cyclical, with periods when stock prices generally rise
                      and periods when stock prices generally decline.

                      market returns as well as the average return for the

</TABLE>
    
 
                      As shown, stocks have provided an average annual total
                      return (capital appreciation plus dividend income) for 10
                      years, of +10.6%. Average return may not be useful for
                      forecasting future returns in any particular period, as
                      stock returns are quite volatile from year-to-year.
 
                      This table on U.S. stock market returns should not be
                      viewed as a representation of future returns from the U.S.
                      stock market or the Portfolio. The illustrated returns
                      represent the historical performance of an unmanaged
                      portfolio of securities (before subtracting portfolio
                      transaction costs and other expenses of an investment
                      portfolio), which may be a poor guide to future returns.
                      In addition, the Portfolio is likely to differ in terms of
                      portfolio composition from this particular index, and so
                      the performance of the Portfolio should not be expected to
                      mirror the return provided by such an index.
 
THE PORTFOLIO IS      The investment adviser manages the Portfolio according to
SUBJECT TO MANAGER    the traditional methods of "active" investment management,
RISK                  which involve the buying and selling of securities based
                      upon economic, financial and market analysis and
                      investment judgment. Manager risk refers to the
                      possibility that the Portfolio's investment adviser may
                      fail to effectively execute the Portfolio's investment
                      strategy. As a result, the Portfolio may fail to achieve
                      its stated objective.

WHO SHOULD            The U.S. Growth Portfolio is intended for investors who
INVEST                are seeking long-term capital appreciation, and who do not
                      need to earn current income from their investment in the
LONG-TERM INVESTORS   Portfolio. Because of the risks associated with common
SEEKING CAPITAL       stock investments, the Portfolio is intended to be a
APPRECIATION          long-term investment vehicle and is not designed to
                      provide investors with a means of speculating on
                      short-term stock market movements. Investors should be
                      able to tolerate sudden, sometimes

                      substantial fluctuations in the value of their investment.
                      Investors who engage in excessive account activity
                      generate additional costs which are borne by all the
                      Portfolio's shareholders. In order to minimize such costs,
                      the Portfolio has adopted the following policies. The
                      Portfolio 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 Portfolio reserves the
                      right to suspend the offering of its shares.
 
                      Because of these risks, the Portfolio should not be
                      considered 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 wish to
                      purchase shares on a regular, periodic basis (dollar-cost
                      averaging), rather than investing in one lump sum in order
                      to reduce the risk of investing all their monies in common
                      stocks at a particularly unfavorable time. Investors may
                      also wish to complement an investment in the Portfolio
                      with other types of common stock investments.
- --------------------------------------------------------------------------------
 
IMPLEMENTATION        In addition to investing in growth-oriented common stocks,
OF POLICIES           the Portfolio follows a number of additional investment
                      practices to achieve its objective.
                      
 
   
THE PORTFOLIO MAY     Although the Portfolio normally seeks to remain fully
INVEST IN SHORT-TERM  invested in equity securities, the Portfolio may invest in
FIXED INCOME          certain short-term fixed income securities for temporary
SECURITIES            defensive purposes. Such securities may be used to invest
                      uncommitted cash balances, to maintain liquidity to meet
                      shareholder redemptions, or to take a temporary defensive
                      position against potential stock market declines. These
                      securities include: obligations of the United States
                      Government and its agencies or instrumentalities;
                      commercial paper, bank certificates of deposit, and
                      bankers' acceptances; and repurchase agreements
                      collateralized by these securities.
                      
                      
                      
                      
    
 
   
THE PORTFOLIO MAY     The Portfolio may lend its investment securities to
LEND ITS SECURITIES   qualified institutional investors for either short-term or
                      long-term purposes of realizing additional net investment
                      income. Loans of securities by the Portfolio will be
                      collateralized by cash, letters of credit, or securities
                      issued or guaranteed by the U.S. Government or its
                      agencies or instrumentalities. The collateral will equal
                      at least 100% of the current market value of the loaned

PORTFOLIO TURNOVER IS Although it generally seeks to invest for the long term,
NOT EXPECTED TO       the Portfolio retains the right to sell securities
EXCEED 100%           irrespective of how long they have been held. It is
                      anticipated that the annual portfolio turnover rate of the
                      Portfolio will not exceed 100%. A turnover rate of 100%
                      would occur, for example, if all of the securities of the
                      Portfolio were replaced within a one-year period.
                      
                      
    
 
   
DERIVATIVE            Derivatives are instruments whose values are linked to or
INVESTING             derived from an underlying security or index. The most
                      common and conventional types of derivative securities are
                      futures and options.

THE PORTFOLIO MAY     The Portfolio may invest in futures contracts and options,
INVEST IN DERIVATIVE  but only to a limited extent. Specifically, a Portfolio of
SECURITIES            the Fund may enter into futures contracts provided that
                      not more than 5% of its assets are required as a futures
                      contract deposit; in addition, a Portfolio 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
                      Portfolio's assets.
    
 
   
                      Futures contracts and options may be used for several
                      common fund management strategies; to maintain cash
                      reserves while simulating full investment, to facilitate
                      trading, to reduce transaction costs, or to seek higher
                      investment returns when a specific futures contract is
                      priced more attractively than other futures contracts or
                      the underlying security or index.
    
 
   
FUTURES AND OPTIONS   The primary risks associated with the use of futures
POSE CERTAIN RISKS    contracts and options are: (i) imperfect correlation
                      between the change in market value of the stocks held by
                      the Portfolio and the prices of futures 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 Portfolio's underlying securities. The risk
                      that the Portfolio will be unable to close out a futures
                      position will be minimized by entering into such
                      transactions on a national exchange with an active and
                      liquid secondary market.
    
 
                      The risk of loss in trading futures contracts in some
                      strategies can be substantial, due both to the low margin
                      deposits required and the extremely high degree of
                      leverage involved in futures pricing. As a result, a
                      relatively small price movement in a futures contract may
                      result in immediate and substantial loss (or gain) to the
                      Portfolio. When investing in futures contracts, the
                      Portfolio will segregate cash or cash equivalents in the
                      amount of the underlying obligation.

INVESTMENT            The Portfolio has adopted certain limitations on its

                      These investment limitations are considered at the time
                      investment securities are purchased. The limitations
                      described here and in the Statement of Additional
                      Information are fundamental and so may be changed only

MANAGEMENT OF         The Fund is a member of The Vanguard Group of Investment
THE PORTFOLIO         Companies, a family of more than 30 investment companies
                      with more than 90 distinct investment portfolios and total
VANGUARD ADMINISTERS  assets in excess of $170 billion. Through their
AND DISTRIBUTES       jointly-owned subsidiary, The Vanguard Group, Inc.
THE PORTFOLIO         ("Vanguard"), the Fund and the other funds in the Group
                      obtain at cost virtually all of their corporate
                      management, administrative and distribution services.
                      Vanguard also provides investment advisory services on an
                      at-cost basis to certain Vanguard funds. As a result of
                      Vanguard's unique corporate structure, the Vanguard funds
                      have costs substantially lower than those of most
                      competing mutual funds. In 1994, the average expense ratio
                      (annual costs including advisory fees divided by average
                      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
                      Directors set broad policies for the Fund and choose its
                      Officers. A list of the Directors and Officers of the Fund
                      and a statement of their present positions and principal
                      occupations during the past five years can be found in the
                      Statement of Additional Information.
 
                      Vanguard employs a supporting staff of management and
                      administrative personnel needed to provide the requisite
                      services to the funds and also furnishes the funds with
                      necessary office space, furnishings and equipment. Each
                      fund pays its share of Vanguard's total expenses, which
                      are allocated among the funds under methods approved by
                      the Board of Directors (Trustees) of each fund. In
                      addition, each fund bears its own direct expenses, such as
                      legal, auditing, and custodian fees.
 
                      Vanguard provides distribution and marketing services to
                      the funds. The funds are available on a no-load basis,
                      (i.e., there are no sales commissions or 12b-1 fees).
                      However, each fund bears its allocated share of the
                      Group's distribution costs.

INVESTMENT            Lincoln Capital Management Company ("Lincoln"), 200 South
ADVISER               Wacker Drive, Chicago, IL 60606, serves as the adviser to
                      the Portfolio. Lincoln is responsible for the investment
LINCOLN CAPITAL       management of the assets in the Portfolio and discharges
SERVES AS ADVISER     its responsibilities subject to the control of the
TO THE PORTFOLIO      Officers and Directors of the Portfolio.
 
   
                      Lincoln, an investment advisory firm founded in 1967,
                      currently provides investment counseling services to a
                      limited number of clients, most of which are institutional
                      clients, such as pension funds. Currently, Lincoln holds
                      discretionary management authority with respect to
                      approximately $33 billion in assets.
    
 
                      Lincoln employs a team of investment professionals who
                      participate in investment strategy formulation and issue
                      selection. Client equity portfolios are similar in terms
                      of their stock composition. The individuals responsible

                      the implementation of Lincoln's strategy for the U.S.
                      Growth Portfolio, who have served in this capacity since
                      Lincoln became the Portfolio's adviser in August 1987, are
                      J. Parker Hall III, President of Lincoln, and David M.
                      Fowler, Vice President of Lincoln.
 
   
                      The Portfolio pays Lincoln an advisory fee calculated by
                      applying varying percentage rates to the average month-end
                      net assets of the Portfolio. The maximum rate is .40% on
                      the first $25 million of net assets. The rate decreases to
                      .35% on the next $125 million of net assets, to .25% on
                      the next $350 million of net assets to .20% on the next
                      $500 million of net assets, .15% on the next $1.5 billion
                      of assets and .10% on assets in excess of $2.5 billion.
                      The agreement does not provide for an incentive
                      fee/penalty based on performance. For the year ended
                      August 31, 1995, the investment advisory fee paid to
                      Lincoln represented an effective annual rate of .19 of 1%
                      of the Portfolio's average net assets.
    
 
                      The investment advisory agreement with Lincoln authorizes
                      the adviser to select brokers or dealers to execute
                      purchases and sales of the Portfolio's 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 Portfolio has authorized Lincoln to pay higher
                      commissions in recognition of brokerage services felt
                      necessary for the achievement of better execution,
                      provided Lincoln believes this to be in the best interest
                      of the Portfolio. Although the Portfolio does not market
                      its shares through intermediary brokers or dealers, the
                      Portfolio may place orders for the Portfolio with
                      qualified broker-dealers who recommend the Portfolio 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 Board of Directors may, without the approval of
                      shareholders, provide for: (a) the employment of a new
                      investment adviser pursuant to the terms of a new advisory
                      agreement either as a replacement for an existing adviser
                      or as an additional adviser; (b) a change in the terms of
                      an advisory agreement; and (c) the continued employment of
                      an existing adviser on the same advisory contract terms
                      where a contract has been assigned because of a change in
                      control of the adviser. Any such change will only be made
                      upon not less than 30 days, prior written notice to
                      shareholders of the Portfolio which shall include
                      substantially the information concerning the adviser that
                      would have normally been included in a proxy statement.

PERFORMANCE           The table below shows the investment results for the
RECORD                Portfolio for several periods throughout the Portfolio's
                      lifetime, both as Ivest Fund and as Vanguard U.S. Growth
                      Portfolio. The results shown represent "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 unmanaged Standard & Poor's 500 Composite
                      Stock Price Index, a widely-used barometer of stock market
                      activity; and the Consumer Price Index, a statistical

                      The results should not be considered a representation of
                      the total return from an investment made in the Portfolio
                      today. The periods shown were generally favorable ones for
                      stock market investing. This information is provided to
                      help you better understand the Portfolio and may not
                      provide a basis for comparison with other investments or
                      mutual funds which use a different method to calculate
                      performance. In weighing these performance figures, you
                      should note that the Portfolio was managed by a different
                      adviser through August 31, 1987.

                      employer-sponsored retirement savings plan, dividend and
                      capital gains distributions from the Portfolio ordinarily

                      employer-sponsored retirement and savings plans are
                      governed by complex tax rules. If you participate in such

THE SHARE PRICE OF    The Portfolio's share price or "net asset value" is
THE PORTFOLIO         calculated each business day after the close of regular
                      trading (generally 4:00 p.m. Eastern time) of the New York
                      Stock Exchange. Net asset value per share is computed by
                      adding up the total value of the Portfolio's investments
                      and other assets, subtracting any of its liabilities, or
                      debts, and then dividing by the number of outstanding
                      shares of the Portfolio.
    
 
   
                      Securities listed on a U.S. exchange are valued at the
                      latest quoted sale price on the day the valuation is made.
                      Securities listed on a U.S. exchange not traded on the
                      valuation date are valued at the mean of the bid and ask
                      prices. If events which

                      materially affect the value of a Portfolio's investments
                      occur after the close of the securities markets on which
                      such securities are primarily traded, those investments
                      will be priced at "fair value". All prices of listed
                      securities are taken from the exchange where the security
                      is primarily traded. Securities regularly traded in the
                      over-the-counter market for which market quotations are
                      readily available will be valued at the latest quoted bid
                      price. 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. Other assets and securities for which no
                      quotations are readily available will be valued in a
                      manner determined in good faith by the Board of Directors.
    
 
                      The Portfolio's share price can be found daily in the
                      mutual fund listings of most major newspapers under the
                      heading of The Vanguard Group.

                      call a meeting of shareholders for the purpose of voting
                      upon the question of removal of a Director or Directors if
                      such a meeting is requested in writing by the holders of
                      not less than 10% of the outstanding shares of the Fund.

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

YIELD AND TOTAL
RETURN                From time to time the Portfolio may advertise its yield
                      and total return. Both yield and total return figures are
                      based on historical earnings and are not intended to
                      indicate future performance. The "total return" of the
                      Portfolio refers to the average annual compounded rates of
                      return over one-, five- and ten- year periods or for the
                      life of the Portfolio (as stated in the advertisement)
                      that would equate an initial amount invested at the
                      beginning of a stated period to the ending redeemable
                      value of the investment, assuming the reinvestment of all
                      dividend and capital gains distributions.
    
 
   
                      In accordance with industry guidelines set forth by the
                      U.S. Securities and Exchange Commission, the "thirty-day
                      yield" of the Portfolio is calculated by dividing net
                      investment income per share earned during a thirty-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 Portfolio's securities and
                      is net of all expenses and all recurring and nonrecurring
                      charges that have been applied to all shareholder
                      accounts. The yield calculation assumes that 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 Portfolio to
                      maintain its books and records, and so the advertised
                      thirty-day yield may not fully reflect the income paid to
                      an investor's account.

INVESTMENT
OBJECTIVE

THE PORTFOLIO SEEKS
TO PROVIDE LONG-TERM
CAPITAL GROWTH        The Portfolio invests primarily in equity securities of
                      companies based outside the United States. The objective
                      of the Portfolio is to provide long-term capital
                      appreciation. Dividend income is expected to be incidental
                      to this objective. There is no assurance that the
                      Portfolio will achieve its objective.
 
                      The investment objective of the Portfolio is fundamental,
                      and so cannot be changed without the approval of a
                      majority of the Portfolio's shareholders.

INVESTMENT
POLICIES

THE PORTFOLIO INVESTS
PRIMARILY IN COMMON
STOCKS                The Portfolio invests chiefly in equity securities,
                      including common stocks and securities convertible into
                      common stocks, which offer favorable prospects for capital
                      growth but little current income. The Portfolio is managed
                      without regard to tax ramifications.
 
   
                      The Portfolio invests primarily in growth-oriented equity
                      securities of seasoned companies located outside the
                      United States. The Portfolio seeks to diversify its assets
                      among as many as thirty foreign stock markets, including
                      Japan, the United Kingdom, Germany, France, Switzerland,
                      the Netherlands, Sweden, Australia, Hong Kong and
                      Singapore. Schroder Capital Management International,
                      adviser to the Portfolio, believes that both the selection
                      of individual stocks and the allocation of the Portfolio's
                      assets across foreign stock markets are important in
                      managing an international equity portfolio. Within each
                      country, the adviser seeks to invest in securities of
                      companies with consistent above-average earnings prospects
                      whose values, as deemed by the adviser, are not yet
                      recognized by the stock market.
    
 
                      Besides investing in equity securities, the International
                      Growth Portfolio may also enter into forward foreign
                      currency exchange contracts in order to protect against

                      Investing in foreign stock markets poses certain unique
                      risks compared with investing in U.S. stock markets. See
                      "Investment Risks" for a description of the risks
                      involved.
 
                      Besides investing in equity securities, the Portfolio may
                      utilize stock index futures contracts and options to a
                      limited extent. In addition, although the Portfolio will
                      normally remain fully invested in equity securities, the
                      Portfolio may temporarily invest in certain short-term
                      fixed income securities. See "Implementation of Policies"
                      for a description of these and other investment practices
                      of the Portfolio.
 
   
                      The Portfolio is responsible for voting the shares of all
                      securities it holds.
    
 
                      The investment policies described above are not
                      fundamental policies and therefore may be changed by the
                      Board of Directors without shareholder approval. However,
                      shareholders would be notified prior to any material
                      change in the Portfolio's policies.

INVESTMENT RISKS      As a mutual fund investing in equity securities, the
                      Portfolio is subject to market risk -- i.e., the
THE PORTFOLIO IS      possibility that stock prices in general will decline over

                      and periods when stock prices generally decline.
   

INTERNATIONAL STOCKS  Investments in foreign stock markets can be as volatile,
MAY BE MORE VOLATILE  if not more volatile, than investments in U.S. markets. To
THAN U.S. STOCKS      illustrate the volatility of foreign stock market returns
                      for the U.S. dollar-based investor, the following table
                      sets forth the extremes for foreign stock market returns
                      as well as the average return for the period from 1969 to
                      1994, as measured by the Morgan Stanley Capital
                      International Europe, Australia, Far East (EAFE) Index:

                      As shown, over the period from 1969 to 1994, international
                      (non-U.S.) stocks have provided an average annual total
                      return, for 10 years, of +16.0%. By comparison, the annual
                      total return, on average, for U.S. stocks during this same
                      period was +12.4% (as measured by the Standard & Poor's
                      500 Composite Stock Price Index). Note, however, that the
                      period from 1969 to 1994 was a favorable one for foreign
                      stock market investing. As a result, the figures on total
                      return and stock market volatility are provided here only
                      as a guide to potential market risk, and may not be useful
                      for forecasting future returns in any particular period.
    
 
   
                      The table on international stock market returns should not
                      be viewed as a representation of future returns from
                      international stock markets of the Portfolio.

                      The illustrated returns represent the historical
                      performance of unmanaged portfolios of securities (before
                      subtracting portfolio transaction costs and other expenses
                      of an investment portfolio), which may be a poor guide to
                      future returns. In addition, the Portfolio is likely to
                      differ in terms of portfolio composition from the EAFE
                      Index, and so the performance of the Portfolio should not
                      be expected to mirror the return provided by the Index.
    
 
   
INTERNATIONAL STOCKS
ALSO EXPOSE INVESTORS
TO CURRENCY AND OTHER
RISKS                 For U.S. investors, the returns of foreign investments,
                      such as those held by the Portfolio, are influenced by not
                      only the returns on foreign common stocks themselves, but
                      also by currency risk -- i.e., changes in the value of the
                      currencies in which the stocks are denominated. In a
                      period when the U.S. dollar generally rises against
                      foreign currencies, the returns on foreign stocks for a
                      U.S. investor may be diminished. By contrast, in a period
                      when the U.S. dollar generally declines, the returns on
                      foreign stocks may be enhanced.
    
 
                      Other risks and considerations of international investing
                      include the following: differences in accounting, auditing
                      and financial reporting standards; generally higher
                      commission rates on foreign portfolio transactions; the
                      smaller trading volumes and generally lower liquidity of
                      foreign stock markets, which may result in greater price
                      volatility; foreign withholding taxes payable on the
                      Portfolio's foreign securities, which may reduce dividend
                      income payable to shareholders; the possibility of
                      expropriation or confiscatory taxation; adverse changes in
                      investment or exchange control regulations; difficulty in
                      obtaining a judgment from a foreign court; political
                      instability which could affect U.S. investment in foreign
                      countries; and potential restrictions on the flow of
                      international capital.
 
THE PORTFOLIO IS
SUBJECT TO
MANAGER RISK          The investment adviser manages the Portfolio according to
                      the traditional methods of "active" investment management,
                      which involve the buying and selling of securities based
                      upon economic, financial and market analysis and
                      investment judgment. Manager risk refers to the
                      possibility that the Portfolio's investment adviser may
                      fail to execute the Portfolio's investment strategy
                      effectively. As a result, the Portfolio may fail to
                      achieve its stated objective.
- --------------------------------------------------------------------------------
 
WHO SHOULD
INVEST

LONG-TERM INVESTORS
SEEKING CAPITAL
APPRECIATION          The Portfolio is intended for investors who are seeking
                      long-term capital appreciation, and who do not need to
                      earn current income from their investment in the
                      Portfolio. Because of the risks associated with common
                      stock investments, the Portfolio is intended to be a
                      long-term investment vehicle and is not designed to
                      provide investors with a means of speculating on
                      short-term stock market movements. Investors should be
                      able to tolerate sudden, sometimes substantial
                      fluctuations in the value of their investment. Investors
                      in the Portfolio should be cognizant of the unique risks
                      of international investing, including their exposure to
                      currency fluctuations. Investors who engage in excessive
                      account activity generate additional costs which are borne
                      by all of the Portfolio's shareholders. In order to
                      minimize such costs, the Portfolio has adopted the
                      following policies. The Portfolio 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,
 
                                        6
<PAGE>   49
 
                      the Portfolio has adopted exchange privilege limitations
                      as described in the section "Exchange Privilege
                      Limitations." Finally, the Portfolio reserves the right to
                      suspend the offering of its shares.
 
   
                      Because of the risks involved, the Portfolio should not be
                      considered 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 wish to
                      purchase shares on a regular, periodic basis (dollar-cost
                      averaging), rather than investing in one lump sum in order
                      to reduce the risk of investing all their monies in common
                      stocks at a particularly unfavorable time. Investors may
                      also wish to complement an investment in the Portfolio
                      with other types of common stock investments.

IMPLEMENTATION
OF POLICIES

THE PORTFOLIO MAY
ENTER INTO FORWARD
CURRENCY CONTRACTS    In addition to investing in growth-oriented common stocks,
                      the Portfolio follows a number of additional investment
                      practices to achieve its objective.
 
                      The Portfolio may enter into forward foreign currency
                      exchange contracts. Such contracts are used to protect the
                      Portfolio's securities against uncertainty in the level of
                      future foreign exchange rates. The Portfolio may not enter
                      into such contracts for speculative purposes.
 
                      A forward foreign currency exchange contract is an
                      obligation to purchase or sell a specific currency at a
                      future date, which may be any fixed number of days from
                      the date of the contract agreed upon by the parties, at a
                      price set at the time of the contract. These contracts may
                      be bought or sold to protect the Portfolio to a limited
                      extent against adverse changes in exchange rates between
                      foreign currencies and the U.S. dollar. Such contracts,
                      which protect the value of a Portfolio's investment
                      securities against a decline in the value of a currency,
                      do not eliminate fluctuations in the underlying prices of
                      the securities. They simply establish an exchange rate at
                      a future date. Also, although such contracts tend to
                      minimize the risk of loss due to a decline in the value of
                      the hedged currency, at the same time they tend to limit
                      any potential gain that might be realized should the value
                      of such currency increase.
 
   
THE PORTFOLIO MAY
INVEST IN SHORT-TERM
FIXED INCOME
SECURITIES            Although the Portfolio normally seeks to remain fully
                      invested in equity securities, the Portfolio may invest
                      temporarily in certain short-term fixed income securities.
                      Such securities may be used to invest uncommitted cash
                      balances, to maintain liquidity to meet shareholder
                      redemptions, or to take a temporary defensive position
                      against potential stock market declines. These securities
                      include: obligations of the United States Government and
                      its agencies or instrumentalities; commercial paper, bank
                      certificates of deposit, and bankers' acceptances; and
                      repurchase agreements collateralized by these securities.
    
 
   
THE PORTFOLIO MAY
LEND ITS SECURITIES   The Portfolio may lend its investment securities to
                      qualified institutional investors for either short-term or
                      long-term purposes of realizing additional net investment
                      income. Loans of securities by the Portfolio will be
                      collateralized by cash, letters of credit, or securities
                      issued or guaranteed by the U.S. Government or its
                      agencies or instrumentalities. The collateral will equal
                      at least 100% of the current market value of the loaned
                      securities.

PORTFOLIO TURNOVER IS
NOT EXPECTED TO
EXCEED 100%           Although it generally seeks to invest for the long term,
                      the Portfolio retains the right to sell securities
                      irrespective of how long they have been held. It is
                      anticipated that the annual turnover rate of the Portfolio
                      will not exceed 100%. A turnover rate of 100% would occur,
                      for example, if all of the securities of the Portfolio
                      were replaced within a one-year period.
    
 
   
DERIVATIVE
INVESTING
                      Derivatives are instruments whose values are linked to or
                      derived from an underlying security or index. The most
                      common and conventional types of derivative securities are
                      futures and options.
    
 
   
THE PORTFOLIO MAY
INVEST IN DERIVATIVE
SECURITIES
                      The Portfolio may invest in futures contracts and options,
                      but only to a limited extent. Specifically, a Portfolio of
                      the Fund may enter into futures contracts provided that
                      not more than 5% of its assets are required as a futures
                      contract deposit; in addition, a Portfolio 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
                      Portfolio's assets.
    
 
   
                      Futures contracts and options may be used for several
                      common fund management strategies: to maintain cash
                      reserves while simulating full investment, to facilitate
                      trading, to reduce transaction costs, or to seek higher
                      investment returns when a specific futures contract is
                      priced more attractively than other futures contracts or
                      the underlying security or index.
    
 
   
FUTURES AND OPTIONS
POSE CERTAIN RISKS    The primary risks associated with the use of futures
                      contracts and options are: (i) imperfect correlation
                      between the change in market value of the stocks held by a
                      Portfolio and the prices of futures 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 Portfolio's underlying securities. The risk that the
                      Portfolio will be unable to close out a futures position
                      will be minimized by entering into such transactions on a
                      national exchange with an active and liquid secondary
                      market.
    
 
                      The risk of loss in trading futures contracts in some
                      strategies can be substantial, due both to the low margin
                      deposits required and the extremely high degree of
                      leverage involved in futures pricing. As a result, a
                      relatively small price movement in a futures contract may
                      result in immediate and substantial loss (or gain) to the
                      investor. When investing in futures contracts, the
                      Portfolio will segregate cash or cash equivalents in the
                      amount of the underlying obligation.

INVESTMENT
LIMITATIONS

THE PORTFOLIO HAS
ADOPTED CERTAIN
FUNDAMENTAL
LIMITATIONS           The Portfolio has adopted certain limitations on its
                      investment practices. Specifically, the Portfolio will
                      not:
 
                      (a) with respect to 75% of its assets, invest more than 5%
                          of its assets in the securities of any single company,
                          excluding obligations of the U.S. government;
 
                      (b) with respect to 75% of its assets, purchase more than
                          10% of the outstanding voting securities of any
                          issuer;

<PAGE>   51
 
                      (c) invest more than 5% of its assets in the securities of
                          companies that have a continuous operating history of
                          less than 3 years;
 
                      (d) invest more than 25% of its assets in any one
                          industry;
 
                      (e) borrow money, except from a bank and only for
                          temporary or emergency purposes to facilitate the
                          meeting of redemption requests (not for leverage); and
 
                      (f) pledge, mortgage or hypothecate assets to an extent
                          greater than 15% of the value of its gross assets.
 
                      These investment limitations are considered at the time
                      investment securities are purchased. The limitations
                      described here and in the Statement of Additional
                      Information are fundamental and so may be changed only
                      with the approval of a majority of the Portfolio's
                      shareholders.

MANAGEMENT OF
THE PORTFOLIO

VANGUARD
ADMINISTERS AND
DISTRIBUTES THE
PORTFOLIO             The Portfolio is a member of The Vanguard Group of
                      Investment Companies, a family of more than 30 investment
                      companies with more than 90 distinct investment
                      portfolios and total assets in excess of $170 billion.
                      Through its jointly-owned subsidiary, The Vanguard Group,
                      Inc. ("Vanguard"), the Portfolio and the other funds in
                      the Group obtain at cost virtually all of their corporate
                      management, administrative and distribution services.
                      Vanguard also provides investment advisory services on an
                      at-cost basis to certain Vanguard funds. As a result of
                      Vanguard's unique corporate structure, the Vanguard funds
                      have costs substantially lower than those of most
                      competing mutual funds. In 1994, the average expense
                      ratio (annual costs including advisory fees divided by
                      average 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
                      Directors set broad policies for the Fund and choose its
                      officers. A list of the Directors and Officers of the Fund
                      and a statement of their present positions and principal
                      occupations during the past five years can be found in the
                      Statement of Additional Information.
 
                      Vanguard employs a supporting staff of management and
                      administrative personnel needed to provide the requisite
                      services to the funds and also furnishes the funds with
                      necessary office space, furnishings and equipment. Each
                      fund pays its share of Vanguard's total expenses, which
                      are allocated among the funds under methods approved by
                      the Board of Directors (Trustees) of each fund. In
                      addition, each fund bears its own direct expenses, such as
                      legal, auditing and custodian fees.
 
                      Vanguard provides distribution and marketing services to
                      the funds. The funds are available on a no-load basis,
                      (i.e., there are no sales commissions or 12b-1 fees).
                      However, each fund bears its allocated share of the
                      Group's distribution costs.

ADVISER               The Fund employs Schroder Capital Management International
                      Inc. ("Schroder Capital"), 787 Seventh Avenue, New York,
                      NY 10019 as the adviser to the Portfolio. The adviser
                      discharges its responsibilities, subject to the control of
                      the Officers and Directors of the Fund.
 
   
SCHRODER CAPITAL
SERVES AS ADVISER TO
THE PORTFOLIO         Schroder Capital is a wholly-owned subsidiary of Schroders
                      PLC. Schroders PLC is the holding company parent of a
                      large worldwide group of banks and financial service
                      companies (referred to as "The Schroder Group") with
                      associated companies and branch and representative offices
                      located in twenty-four countries. The Schroder Group
                      specializes in providing investment management services,
                      with funds under management currently in excess of $102
                      billion.
    
 
                      Richard Foulkes, Executive Vice President of Schroder
                      Capital, serves as Portfolio Manager, a position he has
                      held since 1981. He is supported by research teams in
                      seven offices world-wide and by four teams of regional
                      specialists in their London office.
 
   
                      The Portfolio pays Schroder Capital a basic advisory fee
                      calculated by applying varying percentage rates to the
                      average month-end net assets of the Portfolio. The maximum
                      rate is .350 of 1% for the first $50 million of net
                      assets. This rate decreases to .175 of 1% on the next $950
                      million of net assets and .125% on net assets in excess of
                      $1 billion. This basic advisory fee is increased or
                      decreased by applying an adjustment formula based on the
                      investment performance of the Portfolio relative to the
                      investment record of the Morgan Stanley Capital
                      International Europe, Australia, Far East Index ("EAFE")
                      over the preceding 36-month period as follows:

                      The incentive/penalty fee adjustment for assets in excess

                      ending February 29, 1996, and until that date the
                      incentive/penalty fee adjustment on assets in excess of $1
                      billion will be computed based on a comparison of the
                      investment performance of the Portfolio and that of

                      the EAFE Index over the number of months that have elapsed
                      between March 1, 1993 and the end of the quarter for which
                      the fee is computed.
 
   
                      For the fiscal year ended August 31, 1995, the investment
                      advisory fee paid to Schroder Capital represented an
                      effective annual rate of .14 of 1% of the Portfolio's
                      average month-end net assets before an increase of .02 of
                      1% based on performance.
    
 
                      The investment advisory agreement with Schroder Capital
                      authorizes the adviser to select brokers or dealers to
                      execute purchases and sales of the Portfolio's 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 Portfolio has authorized Schroder Capital to pay
                      higher commissions in recognition of brokerage services
                      felt necessary for the achievement of better execution,
                      provided the investment adviser believes this to be in the
                      best interest of the Portfolio. Although the Portfolio
                      does not market its shares through intermediary brokers or
                      dealers, the Portfolio may place orders for the Portfolio
                      with qualified broker-dealers who recommend the Portfolio
                      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 Board of Directors may, without the approval of
                      shareholders, provide for: (a) the employment of a new
                      investment adviser pursuant to the terms of a new advisory
                      agreement either as a replacement for an existing adviser
                      or as an additional adviser; (b) a change in the terms of
                      an advisory agreement; and (c) the continued employment of
                      an existing adviser on the same advisory contract terms
                      where a contract has been assigned because of a change in
                      control of the adviser. Any such change will only be made
                      upon not less than 30 days' prior written notice to
                      shareholders of the Portfolio which shall include
                      substantially the information concerning the adviser that
                      would have normally been included in a proxy statement.

PERFORMANCE
RECORD                The table in this section shows the investment results for
                      the Portfolio for several periods throughout the
                      Portfolio's lifetime, both as Ivest Fund and as Vanguard
                      International Growth Portfolio. The results shown
                      represent "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 Morgan Stanley
                      Capital International Europe, Australia, Far East Index
                      ("EAFE"), a diversified portfolio of foreign stocks
                      commonly used as a benchmark of foreign stock market
                      activity; and the Consumer Price Index, a statistical
                      measurement 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 Portfolio
                      today. The periods shown were generally favorable ones
                      for foreign stock market investing. This information is
                      provided to help you better understand the Portfolio and
                      may not provide a basis for

                      received in cash. See "Choosing a Distribution Option" for
                      a description of these distribution methods.
 
                      In order to satisfy certain distribution requirements of
                      the Tax Reform Act of 1986, the Portfolio may declare
                      special year-end dividend and capital gains distributions
                      during December. Such distributions, if received by
                      shareholders by January 31, are deemed to have been paid
                      by the Portfolio and received by shareholders on December
                      31 of the prior year.
 
                      The Portfolio intends to continue to qualify for taxation
                      as a "regulated investment company" under the Internal
                      Revenue Code so that it will not be subject to federal
                      income tax to the extent its income is distributed to
                      shareholders. Dividends paid by the Portfolio from net
                      investment income, whether received in cash or reinvested
                      in additional shares, will be taxable to shareholders as
                      ordinary income. Dividends paid by the Portfolio will
                      generally not qualify for the intercorporate dividends-
                      received deduction.
 
   
                      Distributions paid by the Portfolio from long-term capital
                      gains, whether received in cash or reinvested in
                      additional shares, are taxable, regardless of the length
                      of time you have owned shares in the Portfolio. Capital
                      gains distributions are made when the Portfolio realizes
                      net capital gains on sales of portfolio securities during
                      the year. The Portfolio does not seek to realize any
                      particular amount of capital gains during a year; rather,
                      realized gains are a by-product of portfolio management
                      activities. Consequently, capital gains distributions may
                      be expected to vary considerably from year to year; there
                      will be no capital gains distributions in years when the
                      Portfolio realizes net capital losses.
    
 
                      Note that if you elect to receive 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 Portfolio. Also, keep in mind that
                      if you purchase shares in the Portfolio shortly before the
                      record date for a dividend or capital gains distribution,
                      a portion of your investment will be returned to you as a
                      taxable distribution, regardless of whether you are
                      reinvesting your distributions or receiving them in cash.

                      The Portfolio will notify you annually as to the tax
                      status of dividend and capital gains distributions paid by
                      the Portfolio.
 
THE PORTFOLIO MAY
"PASS THROUGH"
FOREIGN TAXES         The Portfolio may elect to "pass through" to the
                      Portfolio's shareholders the amount of foreign income
                      taxes paid by the Portfolio. The Portfolio will make such
                      an election only if it deems it to be in the best
                      interests of its shareholders.
 
                      If this election is made, shareholders of the Portfolio
                      will be required to include in their gross income their
                      pro rata share of foreign taxes paid by the Portfolio.
                      However, shareholders will be able to treat their pro rata
                      share of foreign taxes as either an itemized deduction or
                      a foreign tax credit against U.S. income taxes on their
                      tax return.
 
A CAPITAL GAIN OR LOSS
MAY BE REALIZED UPON
EXCHANGE OR
REDEMPTION            A sale of shares of the Portfolio is a taxable event, and
                      may result in a capital gain or loss. A capital gain or
                      loss may be realized from an ordinary redemption of shares
                      or an exchange of shares between two mutual funds (or two
                      portfolios of a mutual fund).
 
                      Dividend distributions, capital gains distributions and
                      capital gains or losses from redemptions and exchanges may
                      be subject to state and local taxes.
 
                      The Portfolio is required to withhold 31% of taxable
                      dividends, capital gains distributions, and redemptions
                      paid to shareholders who have not complied with IRS
                      taxpayer identification regulations. You may avoid this
                      withholding requirement by certifying on your account
                      registration form your proper Social Security or Taxpayer
                      Identification Number and certifying that you are not
                      subject to backup withholding.
 
                      The Fund has obtained a Certificate of Authority to do
                      business as a foreign corporation in Pennsylvania, and
                      does business and maintains an office in that state. In
                      the opinion of counsel, the shares of the Portfolio are
                      exempt from Pennsylvania personal property taxes.
 
                      The tax discussion set forth above is included for general
                      information only. Prospective investors should consult
                      their own tax advisers concerning the tax consequences of
                      an investment in the Portfolio.

THE SHARE PRICE
OF THE PORTFOLIO      The Portfolio's share price or "net asset value" is
                      calculated each business day after the close of regular
                      trading (generally 4:00 p.m. Eastern time) of the New York
                      Stock Exchange. Net asset value per share is computed by
                      adding up the total value of the Portfolio's investments
                      and other assets, subtracting any of its liabilities, or
                      debts, and then dividing by the number of outstanding
                      shares of the Portfolio.
    
 
                      Securities listed on a foreign exchange, as well as
                      American Depository Receipts ("ADRs"), which are traded on
                      U.S. exchanges are valued at the latest quoted sales price
                      available before the time when assets are valued. All
                      prices of listed securities are taken from the exchange
                      where the security is primarily traded. Securities
                      regularly traded in the over-the-counter market for which
                      market quotations are readily available will be valued at
                      the latest quoted bid price. 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. Other assets and
 
                                       13
<PAGE>   56
 
                      securities for which no quotations are readily available
                      will be valued in a manner determined in good faith by the
                      Board of Directors to reflect their fair value.
 
   
                      For purposes of determining the Portfolio's net asset
                      value per share, all assets and liabilities, initially
                      expressed in foreign currencies will be converted into
                      U.S. dollars using the quoted daily exchange rates
                      determined by Morgan Stanley Capital International (MSCI)
                      in the calculation of their various benchmarking indices.
                      This officially quoted daily exchange rate may be
                      determined by MSCI prior to or after the close of a
                      particular foreign securities market. If such quotations
                      are not available, the rate of exchange will be determined
                      in accordance with policies established in good faith by
                      the Board of Directors.
    
 
   
                      The Portfolio's share price can be found daily in the
                      mutual fund listings of most major newspapers under the
                      heading of Vanguard.

GENERAL
INFORMATION           The Fund was organized as Ivest Fund, a Massachusetts
                      Corporation, in 1959. The Fund is now a Maryland
                      Corporation and is authorized to issue 550,000,000 shares
                      with a par value of $1.00 per share. Currently the Fund is
                      offering shares of two Portfolios with 250,000,000 shares
                      allocated to the U.S. Growth Portfolio and 300,000,000
                      shares allocated to the International Growth Portfolio.
    
 
                      The shares of each Portfolio of the Fund are fully paid
                      and non-assessable; have no preference as to conversion,
                      exchange, dividends, retirement or other features; and
                      have no pre-emptive rights. The shares of each Portfolio
                      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.
 
                      The Fund will not hold annual meetings of shareholders
                      except as required by the Investment Company Act of 1940
                      and other applicable law. The Directors of the Fund will
                      call a meeting of shareholders for the purpose of voting
                      upon the question of removal of a Director or Directors if
                      such a meeting is requested in writing by the holders of
                      not less than 10% of the outstanding shares of the Fund.
 
                      All securities and cash of the Portfolio are held by
                      Morgan Guaranty Trust Company, New York, NY. The Vanguard
                      Group, Inc., Valley Forge, PA, serves as the Portfolio's
                      Transfer and Dividend Disbursing Agent. Price Waterhouse
                      LLP, serves as independent accountants for the Fund and
                      will audit its financial statements annually. The Fund is
                      not involved in any litigation.

OPENING AN
ACCOUNT AND
PURCHASING
SHARES                You may open a regular (non-retirement) account, either by
                      mail or wire. Simply complete and return an Account
                      Registration Form and any required legal documentation,
                      indicating the amount you wish to invest. Your purchase
                      must be equal to or greater than the $3,000 minimum
                      initial investment requirement ($1,000 for Uniform
                      Gifts/Transfers to Minors Act accounts). You must open a
                      new Individual Retirement Account by mail (IRA's may not
                      be opened by wire) using a Vanguard IRA Adoption
                      Agreement. Your purchase must be equal to or greater than
                      the $1,000 minimum initial investment requirement, but no
                      more than $2,000 if you are making a regular IRA
                      contribution. Rollover contributions are generally limited
                      to the amount withdrawn within the past 60 days from an
                      IRA or other qualified Retirement Plan. If you need
                      assistance with the forms or have any questions about the
                      Portfolio, please call our Investor Information Department
                      at 1-800-662-7447. Note: For other types of account
                      registrations (e.g., corporations, associations, other
                      organizations, trust or powers of attorney), please call
                      our Investor Information Department to determine which
                      additional forms you may need.
    
 
   
                      The Portfolio's shares are purchased at the
                      next-determined net asset value after your investment has
                      been received. The Portfolio is offered on a no-load basis
                      (i.e., there are no sales commissions or 12b-1 fees).
    
 
   
PURCHASE
RESTRICTIONS          1) Because of the risks associated with common stock
                         investments, the Portfolio is intended to be a
                         long-term investment vehicle and is not designed to
                         provide investors with a means of speculating on
                         short-term market movements. Consequently, the
                         Portfolio reserves the right to reject any specific
                         purchase (and exchange purchase) request. The Portfolio
                         also reserves the right to suspend the offering of
                         shares for a period of time.
    
 
   
                      2) Vanguard will not accept third-party checks to purchase
                         shares of the Fund. Please be sure your purchase check
                         is made payable to the Vanguard Group.
    
 
ADDITIONAL
INVESTMENTS           Subsequent investments to regular accounts may be made by
                      mail ($100 minimum), wire ($1,000 minimum), exchange from
                      another Vanguard Fund account, or Vanguard Fund Express.
                      Subsequent investments to Individual Retirement Accounts
                      may be made by mail ($100 minimum) or exchange from
                      another Vanguard Fund account. In some instances,
                      contributions may be made by wire or Vanguard Fund
                      Express. Please call us for more information on these
                      options.

CHOOSING A

                         capital gains distributions will be reinvested in
                         additional Portfolio shares. This option will be
                         selected for you automatically unless you specify one
                         of the other options.
 
                      2. CASH DIVIDEND OPTION -- Your dividends will be paid in
                         cash and your capital gains will be reinvested in

                      3. ALL CASH OPTION -- Both dividend and capital gains
                         distributions will be paid in cash.

                      Department (1-800-662-2739).
 
                      In addition, an option to invest your cash dividends
                      and/or capital gains distributions in another Vanguard
                      Fund account is available. Please call our Client Services
                      Department (1-800-662-2739) for information. You may also
                      elect Vanguard Dividend Express which allows you to
                      transfer your cash dividends and/or capital gains
                      distributions automatically to your bank account. Please

TAX CAUTION

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

IMPORTANT
INFORMATION

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

DELIVERY              If you would prefer to receive a prospectus for the Fund

                      please call 1-800-231-7870 for additional information. If
                      you elect to do so, you may also receive a paper copy of

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

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

                      initiate a request by writing or by telephoning. Your

DELIVERY OF
REDEMPTION PROCEEDS   Redemption requests received by telephone prior to the
                      close of regular trading on the New York Stock Exchange
                      (generally, 4:00 p.m. Eastern time) are processed on the
                      day of receipt and the redemption proceeds are normally
                      sent on the following business day.
 
                      Redemption requests received by telephone after the close
                      of the Exchange are processed on the business day
                      following receipt and the proceeds are normally sent on
                      the second business day following receipt.
 
                      Redemption proceeds must be sent to you within seven days
                      of receipt of your request in Good Order.
 
                      If you experience difficulty in making a telephone
                      redemption during periods of drastic economic or market
                      changes, your redemption request may be made by regular or
                      express mail. It will be implemented at the net asset
                      value next determined after your request has been received
                      by Vanguard in Good Order. The Portfolio reserves the
                      right to revise or terminate the telephone redemption
                      privilege at any time.
 
                      The Portfolio may suspend the redemption right or postpone
                      payment at times when the New York Stock Exchange is
                      closed, or under any emergency circumstances as determined
                      by the United States Securities and Exchange Commission.
 
                      If the Board of Directors determines that it would be
                      detrimental to the best interests of the Portfolio's
                      remaining shareholders to make payment in cash, the
                      Portfolio may pay the redemption proceeds in whole or in
                      part by a distribution in kind of readily marketable
                      securities.
- --------------------------------------------------------------------------------
 
VANGUARD'S AVERAGE
COST STATEMENT        If you make a redemption from a qualifying account,
                      Vanguard will send you an Average Cost Statement which
                      provides you with the tax basis of the shares you
                      redeemed. Please see "Other Vanguard Services" for
                      additional information.
- --------------------------------------------------------------------------------
 
   
LOW BALANCE FEE
AND MINIMUM
ACCOUNT BALANCE
REQUIREMENT           Due to the relatively high cost of maintaining smaller
                      accounts, the Portfolio will automatically deduct a $10
                      annual fee from non-retirement accounts with balances
                      falling below $2,500 ($1,000 for Uniform Gifts/Transfers
                      to Minors Act accounts). This fee deduction will occur
                      mid-year, beginning in 1996. The fee generally will be
                      waived for investors whose aggregate Vanguard assets
                      exceed $50,000. In addition, the Portfolio reserves the
                      right to liquidate any non-retirement account that is
                      below the minimum initial investment amount of $3,000. If
                      at any time the total investment does not have a value of
                      at least $3,000, you may be notified that the value of
                      your account is below the Portfolio's minimum account
                      balance requirement. You would then be allowed 60 days to
                      make an additional investment before the account is
                      liquidated. Proceeds would be promptly paid to the
                      shareholder.
    
 
   
                      Vanguard will not liquidate your account if it has fallen
                      below $3,000 solely as a result of declining markets
                      (i.e., a decline in a Portfolio's net asset value).

IMPORTANT EXCHANGE
INFORMATION           Before you make an exchange, you should consider the
                      following:
 
                      -  Please read the Portfolio's prospectus before making an
                         exchange. For a copy and for answers to any questions
                         you may have, call our Investor Information Department
                         (1-800-662-7447).
 
                      -  An exchange is treated as a redemption and a purchase.
                         Therefore, you could realize a taxable gain or loss on
                         the transaction.
 
                      -  Exchanges are accepted only if the registrations and
                         Taxpayer Identification numbers of the two accounts are
                         identical.
 
                      -  The shares to be exchanged must be on deposit and not
                         held in certificate form.
 
                                       21
<PAGE>   64
 
   
                      -  New accounts are not currently accepted in
                         Vanguard/Windsor Fund or Vanguard/PRIMECAP Fund.
    
 
                      -  The redemption price of shares redeemed by exchange is
                         the net asset value next determined after Vanguard has
                         received the required documentation 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 Portfolio reserves the right to
                      revise or terminate its provisions, limit the amount of or
                      reject any exchange, as deemed necessary, at any time.
 
                      The exchange privilege is only available in states in
                      which the shares of the Portfolio are registered for sale.
                      The Portfolio's shares are currently registered for sale
                      in all 50 states and the Portfolio intends to maintain
                      such registration.
- --------------------------------------------------------------------------------
 
EXCHANGE
PRIVILEGE
LIMITATIONS           The Portfolio's exchange privilege is not intended to
                      afford shareholders a way to speculate on short-term
                      movements in the market. Accordingly, in order to prevent
                      excessive use of the exchange privilege that may
                      potentially disrupt the management of the Portfolio and
                      increase transactions costs, the Portfolio has established
                      a policy of limiting excessive exchange activity.
 
   
                      Exchange activity generally will not be deemed excessive
                      if limited to TWO SUBSTANTIVE EXCHANGE REDEMPTIONS (AT
                      LEAST 30 DAYS APART) from the Portfolio during any
                      twelve-month period. Notwithstanding these limitations,
                      the Portfolio reserves the right to reject any purchase
                      request (including exchange purchases from other Vanguard
                      portfolios) that is reasonably deemed to be disruptive to
                      efficient portfolio management.

IMPORTANT
INFORMATION
ABOUT TELEPHONE
TRANSACTIONS          The ability to initiate redemptions (except wire
                      redemptions) and exchanges by telephone is automatically
                      established on your account unless you request in writing
                      that telephone transactions on your account not be
                      permitted.
 
                      To protect your account from losses resulting from
                      unauthorized or fraudulent telephone instructions,
                      Vanguard adheres to the following security procedures:
 
                      1. SECURITY CHECK. To request a transaction by telephone,
                         the caller must know (i) the name of the Portfolio;
                         (ii) The 10-digit account number; (iii) the exact name
                         and address used in the registration; and (iv) the
                         Social Security or Employer Identification number
                         listed on the account.
 
                      2. PAYMENT POLICY. The proceeds of any telephone
                         redemption made by mail will be made payable to the
                         registered shareowner and mailed to the address of
                         record, only.
 
                      Neither the Fund nor Vanguard will be responsible for the
                      authenticity of transaction instructions received by
                      telephone, provided that reasonable security procedures
                      have been followed. Vanguard believes that the security
                      procedures
 
                                       22
<PAGE>   65
 
                      described above are reasonable and that if such procedures
                      are followed, you will bear the risk of any losses
                      resulting from unauthorized or fraudulent telephone
                      transactions on your account. If Vanguard fails to follow
                      reasonable security procedures, it may be liable for any
                      losses resulting from unauthorized or fraudulent telephone
                      transactions on your account.

                      available for most taxable accounts opened since January

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

INVESTMENT
OBJECTIVE

THE PORTFOLIO SEEKS
TO PROVIDE LONG-TERM
CAPITAL GROWTH
                      The Portfolio invests primarily in equity securities of
                      companies based outside of the United States. The
                      objective of the Portfolio is to provide long-term capital
                      appreciation. Dividend income is expected to be incidental
                      to this objective. There is no assurance that the
                      Portfolio will achieve its objective.
    
 
                      The investment objective of the Portfolio is fundamental,
                      and so cannot be changed without the approval of a
                      majority of its shareholders.

INVESTMENT
POLICIES

THE PORTFOLIO INVESTS
PRIMARILY IN COMMON
STOCKS
                      The Portfolio invests chiefly in equity securities,
                      including common stocks, which offer favorable prospects
                      for growth, but little current income. The Portfolio is
                      managed without regard to tax ramifications.
    
 
   
                      The Portfolio invests primarily in growth-oriented equity
                      securities of seasoned companies located outside the
                      United States. The Portfolio seeks to diversify its assets
                      among as many as thirty foreign stock markets, including
                      Japan, the United Kingdom, Germany, France, Switzerland,
                      the Netherlands, Sweden, Australia, Hong Kong and
                      Singapore. Schroder Capital Management International,
                      adviser to the Portfolio, believes that both the selection
                      of individual stocks and the allocation of the Portfolio's
                      assets across foreign stock markets are important in
                      managing an international equity portfolio. Within each
                      country, the adviser seeks to invest in securities of
                      companies with consistent above-average earnings prospects
                      whose values are not yet recognized by the stock market.
    
 
                      Besides investing in equity securities, the International
                      Growth Portfolio may also enter into forward foreign
                      currency exchange contracts in order to protect against
                      fluctuations in exchange rates. See "Implementation of
                      Policies" for a description of
 
                                        4
<PAGE>   75
 
                      such contracts. Investing in foreign stock markets poses
                      certain unique risks compared with investing in U.S. stock
                      markets. See "Investment Risks" for a description of the
                      risks involved.
 
                      Besides investing in equity securities, the Portfolio may
                      utilize stock index futures contracts and options to a
                      limited extent. In addition, although the Portfolio will
                      normally remain fully invested in equity securities, the
                      Portfolio may temporarily invest in certain short-term
                      fixed income securities. See "Implementation of Policies"
                      for a description of these and other investment practices
                      of the Portfolio.
 
   
                      The Portfolio is responsible for voting the shares of all
                      securities it holds.
    
 
                      The investment policies described above are not
                      fundamental policies and therefore may be changed by the
                      Board of Directors without shareholder approval. However,
                      shareholders would be notified prior to any material
                      change in the Portfolio's policies.
- --------------------------------------------------------------------------------
 
INVESTMENT RISKS      As a mutual fund investing in equity securities, the
                      Portfolio is subject to market risk -- i.e., the
THE PORTFOLIO IS      possibility that stock prices in general will decline over
SUBJECT TO STOCK      short or even extended periods. Stock markets tend to be
MARKET RISK           cyclical, with periods when stock prices generally rise
                      and periods when stock prices generally decline.
                      
 
   
INTERNATIONAL STOCKS  Investments in foreign stock markets can be as volatile,
MAY BE MORE VOLATILE  if not more volatile, than investments in U.S. markets. To
THAN U.S. STOCKS      illustrate the volatility of foreign stock market returns
                      for the U.S. dollar-based investor, the following table
                      sets forth the extremes for foreign stock market returns
                      as well as the average return for the period from 1969 to
                      1994, as measured by the Morgan Stanley Capital
                      International Europe, Australia, Far East (EAFE) Index:

</TABLE>
    
 
   
                      As shown, over the period from 1969 to 1994, international
                      (non-U.S.) stocks have provided an average annual total
                      return, for 10 years, of +16.0%. By comparison, the annual
                      total return, on average, for U.S. stocks during this same
                      period was +12.4% (as measured by the Standard & Poor's
                      500 Composite Stock Price Index). Note, however, that the
                      period from 1969 to 1994 was a favorable one for foreign
                      stock market investing. As a result, the figures on total
                      return and stock market volatility are provided here only
                      as a guide to potential market risk, and may not be useful
                      for forecasting future returns in any particular period.
    
 
   
                      The table on international stock market returns should not
                      be viewed as a representation of future returns from
                      international stock markets of the Portfolio.

                      The illustrated returns represent the historical
                      performance of unmanaged portfolios of securities (before
                      subtracting portfolio transaction costs and other expenses
                      of an investment portfolio), which may be a poor guide to
                      future returns. In addition, the Portfolio is likely to
                      differ in terms of portfolio composition from the EAFE
                      Index, and so the performance of the Portfolio should not
                      be expected to mirror the return provided by the Index.
 
   
INTERNATIONAL STOCKS
ALSO EXPOSE INVESTORS
TO CURRENCY AND OTHER
RISKS
                      For U.S. investors, the returns of foreign investments,
                      such as those held by the Portfolio, are influenced by not
                      only the returns on foreign common stocks themselves, but
                      also by currency risk--i.e., changes in the value of the
                      currencies in which the stocks are denominated. In a
                      period when the U.S. dollar generally rises against
                      foreign currencies, the returns on foreign stocks for a
                      U.S. investor may be diminished. By contrast, in a period
                      when the U.S. dollar generally declines, the returns on
                      foreign stocks may be enhanced.
    
 
                      Other risks and considerations of international investing
                      include the following: differences in accounting, auditing
                      and financial reporting standards; generally higher
                      commission rates on foreign portfolio transactions; the
                      smaller trading volumes and generally lower liquidity of
                      foreign stock markets, which may result in greater price
                      volatility; foreign withholding taxes payable on the
                      Portfolio's foreign securities, which may reduce dividend
                      income payable to shareholders; the possibility of
                      expropriation or confiscatory taxation; adverse changes in
                      investment or exchange control regulations; difficulty in
                      obtaining a judgment from a foreign court; political
                      instability which could affect U.S. investment in foreign
                      countries; and potential restrictions on the flow of
                      international capital.
 
   
THE PORTFOLIO IS
SUBJECT TO MANAGER
RISK
                      The investment adviser manages the Portfolio according to
                      the traditional methods of "active" investment management,
                      which involve the buying and selling of securities based
                      upon economic, financial and market analysis and
                      investment judgment. Manager risk refers to the
                      possibility that the Portfolio's investment adviser may
                      fail to execute the Portfolio's investment strategy
                      effectively. As a result, the Portfolio may fail to
                      achieve its stated objective.

WHO SHOULD
INVEST

LONG-TERM INVESTORS
SEEKING CAPITAL
APPRECIATION
                      The Portfolio is intended for investors who are seeking
                      long-term capital appreciation, and who do not need to
                      earn current income from their investment in the
                      Portfolio. Because of the risks associated with foreign
                      common stock investments, the Portfolio is intended to be
                      a long-term investment vehicle and is not designed to
                      provide investors with a means of speculating on
                      short-term stock market movements. Investors should be
                      able to tolerate sudden, sometimes substantial
                      fluctuations in the value of their investment. Investors
                      in the Portfolio should be cognizant of the unique risks
                      of international investing, including their exposure to
                      currency fluctuations. Investors who engage in excessive
                      account activity generate additional costs which are borne
                      by all of the Portfolio's shareholders. In order to
                      minimize such costs, the Portfolio has adopted the
                      following policies. The Portfolio 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
    
 
                                        6
<PAGE>   77
 
                      previous excessive trading by the investor. Additionally,
                      the Portfolio reserves the right to suspend the offering
                      of its shares.
 
   
                      Because of the risks involved, the Portfolio should not be
                      considered 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 wish to
                      purchase shares on a regular, periodic basis (dollar-cost
                      averaging), rather than investing in one lump sum in order
                      to reduce the risk of investing all their monies in common
                      stocks at a particularly unfavorable time. Investors may
                      also wish to complement an investment in the Portfolio
                      with other types of common stock investments.

IMPLEMENTATION
OF POLICIES

THE PORTFOLIO MAY
ENTER INTO FORWARD
CURRENCY CONTRACTS    In addition to investing in growth-oriented common stocks,
                      the Portfolio follows a number of additional investment
                      practices to achieve its objective.
 
                      The Portfolio may enter into forward foreign currency
                      exchange contracts. Such contracts are used to protect the
                      Portfolio's securities against uncertainty in the level of
                      future foreign exchange rates. The Portfolio may not enter
                      into such contracts for speculative purposes.
 
   
                      A forward foreign currency exchange contract is an
                      obligation to purchase or sell a specific currency at a
                      future date, which may be any fixed number of days from
                      the date of the contract agreed upon by the parties, at a
                      price set at the time of the contract. These contracts may
                      be bought or sold to protect the Portfolio to a limited
                      extent against adverse changes in exchange rates between
                      foreign currencies and the U.S. dollar. Such contracts,
                      which protect the value of a Portfolio's investment
                      securities against a decline in the value of a currency,
                      do not eliminate fluctuations in the underlying prices of
                      the securities. They simply establish an exchange rate at
                      a future date. Also, although such contracts tend to
                      minimize the risk of loss due to a decline in the value of
                      the hedged currency, at the same time they tend to limit
                      any potential gain that might be realized should the value
                      of such currency increase.
    
 
   
THE PORTFOLIO MAY
INVEST IN SHORT-TERM
FIXED INCOME
SECURITIES
                      Although the Portfolio normally seeks to remain fully
                      invested in equity securities, the Portfolio may invest in
                      certain short-term fixed income securities for temporary
                      defensive purposes. Such securities may be used to invest
                      uncommitted cash balances, to maintain liquidity to meet
                      shareholder redemptions, or to take a temporary defensive
                      position against potential stock market declines. These
                      securities include: obligations of the United States
                      Government and its agencies or instrumentalities;
                      commercial paper, bank certificates of deposit, and
                      bankers' acceptances; and repurchase agreements
                      collateralized by these securities.
    
 
   
THE PORTFOLIO MAY
LEND ITS SECURITIES
                      The Portfolio may lend its investment securities to
                      qualified institutional investors for either short-term or
                      long-term purposes of realizing additional net investment
                      income. Loans of securities by the Portfolio will be
                      collateralized by cash, letters of credit, or securities
                      issued or guaranteed by the U.S. Government or its
                      agencies or instrumentalities. The collateral will equal
                      at least 100% of the current market value of the loaned
                      securities.

PORTFOLIO TURNOVER IS
NOT EXPECTED TO
EXCEED 100%           Although it generally seeks to invest for the long term,
                      the Portfolio retains the right to sell securities
                      irrespective of how long they have been held. It is
                      anticipated that the annual portfolio turnover rate of the
                      Portfolio will not exceed 100%. A turnover rate of 100%
                      would occur, for example, if all of the securities of the
                      Portfolio were replaced within a one-year period.
    
 
   
DERIVATIVE
INVESTING             Derivatives are instruments whose values are linked to or
                      derived from an underlying security or index. The most
                      common and conventional types of derivative securities are
                      futures and options.
    
 
   
THE FUND MAY INVEST
IN DERIVATIVE 
SECURITIES            The Fund may invest in futures contracts and options, but
                      only to a limited extent. Specifically, a Portfolio of the
                      Fund may enter into futures contracts provided that not
                      more than 5% of its assets are required as a futures
                      contract deposit; in addition, a Portfolio 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
                      Portfolio's assets.
    
 
   
                      Futures contracts and options may be used for several
                      common fund management strategies: to maintain cash
                      reserves while simulating full investment, to facilitate
                      trading, to reduce transaction costs, or to seek higher
                      investment returns when a specific futures contract is
                      priced more attractively than other futures contracts or
                      the underlying security or index.
    
 
   
FUTURES AND OPTIONS
POSE CERTAIN RISKS    The primary risks associated with the use of futures
                      contracts and options are: (i) imperfect correlation
                      between the change in market value of the stocks held by
                      the Portfolio and the prices of futures 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 Portfolio's underlying securities. The risk
                      that the Portfolio will be unable to close out a futures
                      position will be minimized by entering into such
                      transactions on a national exchange with an active and
                      liquid secondary market.
    
 
   
                      The risk of loss in trading futures contracts in some
                      strategies can be substantial, due both to the low margin
                      deposits required and the extremely high degree of
                      leverage involved in futures pricing. As a result, a
                      relatively small price movement in a futures contract may
                      result in immediate and substantial loss (or gain) to the
                      investor. When investing in futures contracts, the
                      Portfolio will segregate cash or cash equivalents in the
                      amount of the underlying obligation.

INVESTMENT
LIMITATIONS

THE PORTFOLIO HAS
ADOPTED CERTAIN
FUNDAMENTAL
LIMITATIONS
                      The Portfolio has adopted certain limitations on its
                      investment practices. Specifically, the Portfolio will
                      not:
    
 
                      (a) with respect to 75% of its assets, invest more than 5%
                          of its assets in the securities of any single company,
                          excluding obligations of the U.S. Government;
 
                      (b) with respect to 75% of its assets, purchase more than
                          10% of the outstanding voting securities of any
                          issuer;
 
                                        8
<PAGE>   79
 
                      (c) invest more than 5% of its assets in the securities of
                          companies that have a continuous operating history of
                          less than three years;
 
                      (d) invest more than 25% of its assets in any one
                          industry;
 
                      (e) borrow money, except from a bank and only for
                          temporary or emergency purposes to facilitate the
                          meeting of redemption requests (not for leverage); and
 
                      (f) pledge, mortgage or hypothecate assets to an extent
                          greater than 15% of the value of its gross assets.
 
                      These investment limitations are considered at the time
                      investment securities are purchased. The limitations
                      described here and in the Statement of Additional
                      Information are fundamental and so may be changed only
                      with the approval of a majority of the Portfolio's
                      shareholders.

MANAGEMENT
OF THE PORTFOLIO

VANGUARD
ADMINISTERS AND
DISTRIBUTES THE
PORTFOLIO             The Portfolio is a member of The Vanguard Group of
                      Investment Companies, a family of more than 30 investment
                      companies with more than 90 distinct investment portfolios
                      and total assets in excess of $170 billion. Through their
                      jointly-owned subsidiary, The Vanguard Group, Inc.
                      ("Vanguard"), the Portfolio and the other funds in the
                      Group obtain at cost virtually all of their corporate
                      management, administrative and distribution services.
                      Vanguard also provides investment advisory services on an
                      at-cost basis to certain Vanguard funds. As a result of
                      Vanguard's unique corporate structure, the Vanguard funds
                      have costs substantially lower than those of most
                      competing mutual funds. In 1994, the average expense ratio
                      (annual costs including advisory fees divided by average
                      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
                      Directors set broad policies for the Fund and choose its
                      Officers. A list of the Directors and Officers of the Fund
                      and a statement of their present positions and principal
                      occupations during the past five years can be found in the
                      Statement of Additional Information.
    
 
                      Vanguard employs a supporting staff of management and
                      administrative personnel needed to provide the requisite
                      services to the funds and also furnishes the funds with
                      necessary office space, furnishings and equipment. Each
                      fund pays its share of Vanguard's total expenses, which
                      are allocated among the funds under methods approved by
                      the Board of Directors (Trustees) of each fund. In
                      addition, each fund bears its own direct expenses, such as
                      legal, auditing, and custodian fees.
 
                      Vanguard provides distribution and marketing services to
                      the funds. The funds are available on a no-load basis,
                      (i.e., there are no sales commissions or 12b-1 fees).
                      However, each fund bears its allocated share of the
                      Group's distribution costs.

                      Capital"), 787 Seventh Avenue, New York, NY 10019 serves
                      as the adviser to the Portfolio. The adviser discharges
                      its responsibilities, subject to the control of the

SCHRODER CAPITAL
SERVES AS ADVISER TO
THE PORTFOLIO         Schroder Capital is a wholly-owned subsidiary of Schroders
                      PLC. Schroders PLC is the holding company parent of a
                      large worldwide group of banks and financial service
                      companies (referred to as "The Schroder Group") with
                      associated companies and branch and representative offices
                      located in twenty-four countries. The Schroder Group
                      specializes in providing investment management services,
                      with Group funds under management currently in excess of
                      $102 billion.
    
 
                      Richard Foulkes, Executive Vice President of Schroder
                      Capital, serves as Portfolio Manager for the Portfolio, a
                      position he has held since 1981. He is supported by
                      research teams in seven offices world-wide and by four
                      teams of regional specialists in their London Office.
 
   
                      The Portfolio pays Schroder Capital a basic advisory fee
                      calculated by applying varying percentage rates to the
                      average net assets of the Portfolio. The maximum rate is
                      .350 of 1% for the first $50 million of net assets. This
                      rate decreases to .175 of 1% on the next $950 million of
                      net assets and .125% on net assets in excess of $1
                      billion. This basic advisory fee is increased or decreased
                      by applying an adjustment formula based on the investment
                      performance of the Portfolio relative to the investment
                      record of the Morgan Stanley Capital International Europe,
                      Australia, Far East Index ("EAFE") over the preceding
                      36-month period as follows:

                      average net assets before an increase of .02 of 1% based
                      on performance.
    
 
                      The investment advisory agreement with Schroder Capital
                      authorizes the adviser to select brokers or dealers to
                      execute purchases and sales of the Portfolio's 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 Portfolio has authorized Schroder Capital to pay
                      higher commissions in recognition of brokerage services
                      felt necessary for the achievement of better execution,
                      provided the investment adviser believes this to be in the
                      best interest of the Portfolio. Although the Portfolio
                      does not market its shares through intermediary brokers or
                      dealers, the Portfolio may place orders for the Portfolio
                      with qualified broker-dealers who recommend the Portfolio
                      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 Board of Directors may, without the approval of
                      shareholders, provide for: (a) the employment of a new
                      investment adviser pursuant to the terms of a new advisory
                      agreement either as a replacement for an existing adviser
                      or as an additional adviser; (b) a change in the terms of
                      an advisory agreement; and (c) the continued employment of
                      an existing adviser on the same advisory contract terms
                      where a contract has been assigned because of a change in
                      control of the adviser. Any such change will only be made
                      upon not less than 30 days' prior written notice to
                      shareholders of the Portfolio which shall include
                      substantially the information concerning the adviser that
                      would have normally been included in a proxy statement.

PERFORMANCE
RECORD                The table in this section shows the investment results for
                      the Portfolio for several periods throughout the
                      Portfolio's lifetime, both as Ivest Fund and as Vanguard
                      International Growth Portfolio. The results shown
                      represent "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 Morgan Stanley
                      Capital International Europe, Australia, Far East Index
                      ("EAFE"), a diversified portfolio of foreign stocks
                      commonly used as a benchmark of foreign stock market
                      activity; and the Consumer Price Index, a statistical
                      measurement 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
                      may pay on a current basis.
 
                      The results should not be considered a representation of
                      the total return from an investment made in the Portfolio
                      today. The periods shown were generally favorable ones for
                      stock market investing. This information is provided to
                      help you better

DIVIDENDS,            Dividends consisting of virtually all of the ordinary
CAPITAL GAINS         income of the Portfolio are declared and paid to
AND TAXES             shareholders annually. Capital gains distributions, if
THE PORTFOLIO PAYS    any, will also be made annually. All dividend and capital
DIVIDENDS AND ANY     gains distributions are automatically reinvested in
CAPITAL GAINS         additional shares of the Portfolio.
ANNUALLY

    
                      In order to satisfy certain distribution requirements of
                      the Tax Reform Act of 1986, the Portfolio may declare
                      special year-end dividend and capital gains distributions
                      during December. The Portfolio 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.
 
   
                      If you utilize the Portfolio as an investment option in an
                      employer-sponsored retirement savings plan, dividend and
                      capital gains distributions from the Portfolio will
                      generally not be subject to current taxation, but will
                      accumulate on a tax-deferred basis. In general, employer
                      sponsored retirement and savings plans are governed by a
                      complex set of tax rules. If you participate in such a
                      plan, consult your plan administrator, your plan's Summary
                      Plan Description, or a professional tax adviser regarding
                      the tax consequences of your participation in the plan and
                      of any plan contributions or withdrawals.

THE SHARE PRICE       The Portfolio's share price or "net asset value" is
OF THE PORTFOLIO      calculated each business day after the close of regular
                      trading (generally 4:00 p.m. Eastern time) of the New York
                      Stock Exchange. Net asset value per share is computed by
                      adding up the total value of the Portfolio's investments
                      and other assets, subtracting any of its liabilities, or
                      debts, and then dividing by the number of outstanding
                      shares of the Portfolio.
                      
    
                      Securities listed on a foreign exchange, as well as
                      American Depository Receipts ("ADRs"), which are traded on
                      U.S. exchanges are valued at the latest quoted sale price
                      available before the assets are valued. All prices of
                      listed securities are taken from the exchange where the
                      security is primarily traded. Securities regularly traded
                      in the over-the-counter market for which market quotations
                      are readily available will be valued at the latest quoted
                      bid price. 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. Other assets and securities for which

<PAGE>   83
 
                      no quotations are readily available will be valued in a
                      manner determined in good faith by the Board of Directors
                      to reflect their fair value.
 
   
                      For purposes of determining the Portfolio's net asset
                      value per share, all assets and liabilities initially
                      expressed in foreign currencies will be converted into
                      U.S. dollars using the quoted daily exchange rates
                      determined by Morgan Stanley Capital International (MSCI)
                      in the calculation of their various benchmarking indices.
                      This officially quoted daily exchange rate may be
                      determined by MSCI prior to or after the close of a
                      particular foreign securities market. If such quotations
                      are not available, the rate of exchange will be determined
                      in accordance with policies established in good faith by
                      the Board of Directors.
    
 
   
                      The Portfolio's share price can be found daily in the
                      mutual fund listings of most major newspapers under the
                      heading of Vanguard.

GENERAL
INFORMATION           The Fund was organized as Ivest Fund, a Massachusetts
                      Corporation, in 1959. The Fund is now a Maryland
                      Corporation. The Fund is authorized to issue 550,000,000
                      shares with a par value of $1.00 per share. Currently, the
                      Fund is offering shares of two Portfolios with 250,000,000
                      shares allocated to the U.S. Growth Portfolio and
                      300,000,000 shares allocated to the International Growth
                      Portfolio.
    
 
                      The shares of each Portfolio of the Fund are fully paid
                      and non-assessable; have no preference as to conversion,
                      exchange, dividends, retirement or other features; and
                      have no pre-emptive rights. The shares of each Portfolio
                      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.
 
                      The Fund will not hold annual meetings of shareholders
                      except as required by the Investment Company Act of 1940
                      and other applicable law. The Directors of the Fund will
                      call a meeting of shareholders for the purpose of voting
                      upon the question of removal of a Director or Directors if
                      such a meeting is requested in writing by the holders of
                      not less than 10% of the outstanding shares of the Fund.
 
                      All securities and cash of the Portfolio are held by
                      Morgan Guaranty Trust Company, New York, NY. The Vanguard
                      Group, Inc., Valley Forge, PA, serves as the Portfolio's
                      Transfer and Dividend Disbursing Agent. Price Waterhouse
                      LLP, serves as independent accountants for the Portfolio
                      and will audit its financial statements annually. The
                      Portfolio is not involved in any litigation.

                       INVESTMENT OBJECTIVE AND POLICIES
 
     The following policies supplement the Fund's investment objective and
policies set forth in the Prospectus for each of the Fund's Portfolios.
 
     FUTURES AND OPTIONS  Each Portfolio may enter into stock futures contracts,
options, and options on futures contracts only for several reasons: to maintain
cash reserves while simulating full investment, to facilitate trading, to reduce
transactions costs, or to seek higher investment returns when a futures contract
is priced more attractively than the underlying equity security or index.
Futures contracts provide for the future sale by one party and purchase by
another party of a specified amount of a specific security at a specified future
time and at a specified price. Futures contracts which are standardized as to
maturity date and underlying financial instrument are traded on national futures
exchanges. Futures exchanges and trading are regulated under the Commodity
Exchange Act by the Commodity Futures Trading Commission ("CFTC"), a U.S.
Government Agency.
 
     Although futures contracts by their terms call for actual delivery or
acceptance of the underlying securities, in most cases the contracts are closed
out before the settlement date without the making or taking of delivery. Closing
out an open futures position is done by taking an opposite position ("buying" a
contract which has previously been "sold," "selling" a contract previously
purchased) in an identical contract to terminate the position. Brokerage
commissions are incurred when a futures contract is bought or sold.
 
     Futures traders are required to make a good faith margin deposit in cash or
government securities with a broker or custodian to initiate and maintain open
positions in futures contracts. A margin deposit is intended to assure
completion of the contract (delivery or acceptance of the underlying security)
if it is not terminated prior to the specified delivery date. Minimal initial
margin requirements are established by the futures exchange and may be changed.
Brokers may establish deposit requirements which are higher than the exchange
minimums. Futures contracts are customarily purchased and sold on margin that
may range upward from less than 5% of the value of the contract being traded.
 
                                        1
<PAGE>   88
 
     After a futures contract position is opened, the value of the contract is
marked to market daily. If the futures contract price changes to the extent that
the margin on deposit does not satisfy margin requirements, payment of
additional "variation" margin will be required. Conversely, change in the
contract value may reduce the required margin, resulting in a repayment of
excess margin to the contract holder. Variation margin payments are made to and
from the futures broker for as long as the contract remains open. The Fund
expects to earn interest income on its margin deposits.
 
     Traders in futures contracts may be broadly classified as either "hedgers"
or "speculators." Hedgers use the futures markets primarily to offset
unfavorable changes in the value of securities otherwise held for investment
purposes or expected to be acquired by them. Speculators are less inclined to
own the securities underlying the futures contracts which they trade, and use
futures contracts with the expectation of realizing profits from fluctuations in
the market value of the underlying securities. Each Portfolio intends to use
futures contracts only for bona fide hedging purposes.
 
     Regulations of the CFTC applicable to each Portfolio require that all of
its futures transactions constitute bona fide hedging transactions. Each
Portfolio 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, each
Portfolio 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 each Portfolio upon sale of open futures
contracts.
 
     Although techniques other than the sale and purchase of futures contracts
could be used to control the exposure of a Portfolio's income to fluctuations in
the market value of the underlying securities, the use of futures contracts may
be a more effective means of hedging this exposure. While the Portfolio will
incur commission expenses in both opening and closing out futures positions,
these costs are lower than transaction costs incurred in the purchase and sale
of portfolio securities.
 
     RESTRICTIONS ON THE USE OF FUTURES CONTRACTS  Each Portfolio 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 Portfolio's total assets. In addition, each Portfolio will
not enter into futures contracts to the extent that its outstanding obligations
to purchase securities under these contracts would exceed 20% of the Portfolio's
total assets.
 
     RISK FACTORS IN FUTURES TRANSACTIONS  Positions in futures contracts may be
closed out only on an exchange which provides a secondary market for such
futures. However, there can be no assurance that a liquid secondary market will
exist for any particular futures contract at any specific time. Thus, it may not
be possible to close a futures position. In the event of adverse price
movements, each Portfolio would continue to be required to make daily cash
payments to maintain its required margin. In such situations, if the Portfolio
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, each Portfolio may be required to make delivery of the instruments
underlying futures contracts it holds. The inability to close options and
futures positions also could have an adverse impact on the ability to
effectively hedge it.
 
     Each Portfolio will minimize the risk that it will be unable to close out a
futures contract by only entering into futures contracts which are traded on
national futures exchanges and for which there appears to be a liquid secondary
market.
 
     The risk of loss in trading futures contracts in some strategies can be
substantial, due both to the low margin deposits required, and the extremely
high degree of leverage involved in futures pricing. As a result, a relatively
small price movement in a futures contract may result in immediate and
substantial loss (as well as gain) to the investor. For example, if, at the time
of purchase, 10% of the value of the futures contract is deposited as margin, a
subsequent 10% decrease in the value of the futures contract would result in a
total loss of the margin deposit, before any deduction for the transaction
costs, if the account were then closed out. A 15% decrease would result in a
loss equal to 150% of the original margin deposit if the contract were closed
out. Thus, a purchase or sale of a futures contract may result in losses
 
                                        2
<PAGE>   89
 
in excess of the amount invested in the contract. However, because the futures
strategies of each Portfolio are engaged in only for hedging purposes, the
investment advisers do not believe that the Portfolios are subject to the risks
of loss frequently associated with futures transactions. Each Portfolio would
presumably have sustained comparable losses if, instead of the futures contract,
it had invested in the underlying financial instrument and sold it after the
decline.
 
     Most futures exchanges limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price at the end of a trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price beyond that limit. The daily limit governs only
price movement during a particular trading day and therefore does not limit
potential losses, because the limit may prevent the liquidation of unfavorable
positions. Futures contract prices have occasionally moved to the daily limit
for several consecutive trading days with little or no trading, thereby
preventing prompt liquidation of future positions and subjecting some futures
traders to substantial losses.
 
     FEDERAL TAX TREATMENT OF FUTURES CONTRACTS  Except for transactions each
Portfolio has identified as hedging transactions, each Portfolio is required for
federal income tax purposes to recognize as income for each taxable year its net
unrealized gains and losses on futures contracts held 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 each Portfolio may affect the holding period of such
securities and, consequently, the nature of the gain or loss on such securities
upon disposition.
 
     In order for each Portfolio to continue to qualify for federal income tax
treatment as a regulated investment company, at least 90% of its gross income
for a taxable year must be derived from qualifying income; i.e., dividends,
interest, income derived from loans of securities, and gains from the sale of
securities or foreign currencies, or other income derived with respect to its
business of investing in such stock, 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 Portfolio's annual gross
income. It is anticipated that any net gain realized from the closing out of
futures contracts will be considered gain from the sale of securities and
therefore be qualifying income for purposes of the 90% requirement. In order to
avoid realizing excessive gains on securities held less than three months, each
Portfolio may be required to defer the closing out of futures contracts beyond
the time when it would otherwise be advantageous to do so. It is anticipated
that unrealized gains on futures contracts, which have been open for less than
three months as of the end of the Portfolio's fiscal year and which are
recognized for tax purposes, will not be considered gains on securities held,
less than three months for the purpose of the 30% test.
 
     Each Portfolio 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 Portfolio's fiscal year) on futures
transactions. Such distributions will be combined with distributions of capital
gains realized on the Portfolio's other investments and shareholders will be
advised on the nature of the payments.
 
     FOREIGN INVESTMENTS  The International Growth Portfolio seeks to diversify
its assets among various foreign stock markets. With respect to 65% of its
assets, the Portfolio will invest in the securities of at least three different
countries. Investors should recognize that investing in foreign companies
involves certain special considerations which are not typically associated with
investing in U.S. companies. Since the stocks of foreign companies are
frequently denominated in foreign currencies, and since the International Growth
Portfolio may temporarily hold uninvested reserves in bank deposits in foreign
currencies, the International Growth Portfolio will be affected favorably or
unfavorably by changes in currency rates and in exchange control regulations,
and may incur costs in connection with conversions
 
                                        3
<PAGE>   90
 
between various currencies. The investment policies of the International Growth
Portfolio permit it to enter into forward foreign currency exchange contracts in
order to hedge the Portfolio's holdings and commitments against changes in the
level of future currency rates. Such contracts involve an obligation to purchase
or sell a specific currency at a future date at a price set at the time of the
contract.
 
   
     Special rules govern the Federal income tax treatment of certain
transactions denominated in terms of a currency other than the U.S. dollar or
determined by reference to the value of one or more currencies other than the
U.S. dollar. The types of transactions covered by the special rules include the
following: (i) the acquisition of, or becoming the obligor under, a bond or
other debt instrument (including, to the extent provided in Treasury
regulations, preferred stock); (ii) the accruing of certain trade receivables
and payables; and (iii) the entering into or acquisition of any forward
contract, futures contract, option and similar financial instrument if such
instrument is not marked to market. The disposition of a currency other than the
U.S. dollar by a U.S. taxpayer is also treated as a transaction subject to the
special currency rules. However, foreign currency-related regulated futures
contracts and nonequity options are generally not subject to the special
currency rules if they are or would be treated as sold for their fair market
value at year-end under the marking-to-market rules applicable to other futures
contracts unless an election is made to have such currency rules apply. With
respect to transactions covered by the special rules, foreign currency gain or
loss is calculated separately from any gain or loss on the underlying
transaction and is normally taxable as ordinary gain or loss. A taxpayer may
elect to treat as capital gain or loss foreign currency gain or loss arising
from certain identified forward contracts, futures contracts and options that
are capital assets in the hands of the taxpayer and which are not part of a
straddle. The Treasury Department has authority to issue regulations under which
certain transactions subject to the special currency rules that are part of a
"section 988 hedging transaction" (as defined in the Internal Revenue Code of
1986, as amended, and the Treasury regulations) will be integrated and treated
as a single transaction or otherwise treated consistently for purposes of the
Code. Any gain or loss attributable to the foreign currency component of a
transaction engaged in by a Portfolio which is not subject to the special
currency rules (such as foreign equity investments other than certain preferred
stocks) will be treated as capital gain or loss and will not be segregated from
the gain or loss on the underlying transaction. It is anticipated that some of
the non-U.S. dollar-denominated investments and foreign currency contracts the
International Growth Portfolio may make or enter into will be subject to the
special currency rules described above.
    
 
     As foreign companies are not generally subject to uniform accounting,
auditing and financial reporting standards and practices comparable to those
applicable to domestic companies, there may be less publicly available
information about certain foreign companies than about domestic companies.
Securities of some foreign companies are generally less liquid and more volatile
than securities of comparable domestic companies. There is generally less
government supervision and regulation of stock exchanges, brokers and listed
companies than in the U.S. In addition, with respect to certain foreign
countries, there is the possibility of expropriation or confiscatory taxation,
political or social instability, or diplomatic developments which could affect
U.S. investments in those countries.
 
     Although the International Growth Portfolio will endeavor to achieve most
favorable execution costs in its portfolio transactions, fixed commissions on
many foreign stock exchanges are generally higher than negotiated commissions on
U.S. exchanges. In addition, it is expected that the expenses for custodian
arrangements of the Portfolio's foreign securities will be somewhat greater than
the expenses for the custodian arrangements for handling the U.S. Growth
Portfolio's securities of equal value.
 
     Certain foreign governments levy withholding taxes against dividend and
interest income. Although in some countries a portion of these taxes are
recoverable, the non-recovered portion of foreign withholding taxes will reduce
the income received from the companies comprising the Fund's International
Growth Portfolio. However, these foreign withholding taxes are not expected to
have a significant impact on the International Growth Portfolio, since the
Portfolio's investment objective is to seek long-term capital appreciation and
any income should be considered incidental.

     PORTFOLIO TURNOVER  While the rate of portfolio turnover is not a limiting
factor when management deems changes appropriate, it is anticipated that the
annual turnover rate for each Portfolio will not normally exceed 100%. A rate of
turnover of 100% could occur, for example, if all of the securities held by a
Portfolio are replaced within a period of one year. The portfolio turnover rate
for each Portfolio for each of the fiscal years presented is set forth under
"Financial Highlights," in each Portfolio's Prospectus.
 
     REPURCHASE AGREEMENTS  Each Portfolio along with other members of the
Vanguard Group may invest in repurchase agreements with commercial banks,
brokers or dealers either for defensive purposes due to market conditions or to
generate income from its excess cash balances. A repurchase agreement is an
agreement under which the Portfolio acquires a money market instrument
(generally a security issued by the U.S. Government or an agency thereof, a
banker's acceptance or a certificate of deposit) from a commercial bank, broker
or dealer, subject to resale to the seller at an agreed upon price and date
(normally, the next business day). A repurchase agreement may be considered a
loan collateralized by securities. The resale price reflects an agreed upon
interest rate effective for the period the instrument is held by the Portfolio
and is unrelated to the interest rate on the underlying instrument. In these
transactions, the securities acquired by the Portfolio (including accrued
interest earned thereon) must have a total value in excess of the value of the
repurchase agreement and are held by the Fund's custodian bank until
repurchased. In addition, the Fund's Board of Directors will monitor repurchase
agreement transactions generally and will establish guidelines and standards for
review by the investment adviser of the creditworthiness of any bank, broker or
dealer party to a repurchase agreement. No more than an aggregate of 15% of the
Portfolio's assets, at the time of investment, will be invested in repurchase
agreements having maturities longer than seven days and securities subject to
legal or contractual restrictions on resale, or for which there are no readily
available market quotations.
 
   
     LENDING OF SECURITIES  Each Portfolio may lend its investment securities
for either short-term or long-term purposes 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 investment securities, a Portfolio attempts
to increase its net investment 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 Portfolio.
Each Portfolio may lend its investment securities to qualified brokers, dealers,
banks or other financial institutions, so long as the terms and the structure
and the aggregate amount 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 Portfolio
collateral consisting of cash, an irrevocable letter of credit or securities
issued or guaranteed by the United States Government having 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 Portfolio at any time and (d) the Portfolio receive
reasonable interest on the loan (which may include the Portfolio's investing any
cash collateral in interest bearing short-term investments), any distribution on
the loaned securities and any increase in their market value. The Portfolio will
not lend investment securities if as a result, the aggregate of such loans
exceeds 33 1/3% of the value of the Portfolio's total assets. Loan arrangements
made by the Portfolio will comply with all other applicable regulatory
requirements, including the rules of the New York Stock Exchange, which
presently require the borrower, after notice, to redeliver the securities within
the normal settlement time of three business days. All relevant facts and
circumstances, including the creditworthiness of the broker, dealer or
institution, will be considered in making decisions with respect to the lending
of securities, subject to review by the Fund's Board of Directors.
    
 
     At the present time, the Staff of the Commission does not object if an
investment company pays reasonable negotiated fees in connection with loaned
securities, so long as such fees are set forth in written contract and approved
by the investment company's Directors. In addition, voting rights may pass with
the loaned securities, but if a material event will occur affecting an
investment on loan, the loan must be called and the securities voted.

                             YIELD AND TOTAL RETURN
 
   
     The yield of the U.S. Growth Portfolio of the Fund for the 30-day period
ended August 31, 1995, was 1.76%.
    
 
   
     The average annual total return of each Portfolio of the Fund for certain
periods ended August 31, 1995, is set forth below:

</TABLE>
    
 
     Total return is computed by determining the average compounded rates of
return over the periods set forth above that would equate an initial amount
invested at the beginning of the periods to the ending redeemable value of the
investment.
 
                               PURCHASE OF SHARES
 
     The purchase price of shares of each Portfolio of the Fund is the net asset
value per share next determined after the order is received. The net asset value
per share is calculated as of the close of the New York Stock Exchange on each
day the Exchange is open for business. An order received prior to the close of
the Exchange will be executed at the price computed on the date of receipt; and
an order received after the close of the Exchange will be executed at the price
computed on the next day the Exchange is open.
 
   
     Each Portfolio reserves the right in its sole discretion (i) to suspend the
offering of its shares, (ii) to reject purchase orders when in the judgment of
management such rejection is in the best interest of the Fund, and (iii) to
reduce or waive the minimum investment for or any other restrictions on initial
and subsequent investments for certain fiduciary accounts such as employee
benefit plans or under circumstances where certain economies can be achieved in
sales of a Portfolio's shares.
    
 
   
     STOCK CERTIFICATES  Your purchase will be made in full and fractional
shares of each Portfolio calculated to three decimal places. Shares are normally
held on deposit for shareholders by the Fund, which will send to shareholders a
statement of shares owned at the time of each transaction. This saves the
shareholders the trouble of safekeeping the certificates, and saves the Fund the
cost of issuing certificates. Share certificates are, of course, available at
any time upon written request at no additional cost to shareholders. No
certificates will be issued for fractional shares.
    
 
                              REDEMPTION OF SHARES
 
     Each Portfolio may suspend redemption privileges or postpone the date of
payment (i) during any period that the New York Stock Exchange is closed, or
trading on the Exchange is restricted as determined by the Securities and
Exchange Commission (the "Commission"), (ii) during any period when an emergency
exists as defined by the rules of the Commission as a result of which it is not
reasonably practicable for a Portfolio to dispose of securities owned by it, or
fairly to determine the value of its assets, and (iii) for such other periods as
the Commission may permit.
 
     No charge is made by a Portfolio for redemptions. Any redemption may be
more or less than the shareholder's cost depending on the market value of the
securities held by the Portfolio.
 
     If the Board of Directors determines that it would be detrimental to the
best interests of the remaining shareholders of a Portfolio to make payment
wholly or partly in cash, a Portfolio may pay the redemption price in whole or
in part by a distribution in kind of readily marketable securities held by the
Portfolio in lieu of cash in conformity with applicable rules of the Commission.
Investors may incur brokerage charges on the sale of such securities so received
in payment of redemptions.

     SIGNATURE GUARANTEES  To protect your account, the Fund and Vanguard from
fraud, signature guarantees are required for certain redemptions. Signature
guarantees enable the Fund to verify the identity of a person who has authorized
a redemption from your account. Signature guarantees are required in connection
with: (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 owner(s); and (3) share transfer requests. These requirements are not
applicable to redemptions in Vanguard's prototype plans except in connection
with: (1) distributions made when the proceeds are to be paid to someone other
than the plan participant; (2) certain authorizations to effect exchanges by
telephone; and (3) when proceeds are to be wired. These requirements may be
waived by the Fund in certain instances.
 
     Signature guarantees can be obtained from a bank, broker or any other
guarantor that Vanguard deems acceptable. Notaries public are not acceptable
guarantors.
 
     The signature guarantees must appear either: (1) on the written request for
redemption; (2) on a separate instrument for assignment ("stock power") which
should specify the total number of shares to be redeemed; or (3) on all stock
certificates tendered for redemption and, if shares held by the Fund are also
being redeemed, on the letter or stock power.
 
                       DIVIDENDS, CAPITAL GAINS AND TAXES
 
     The Fund's policy is to distribute annually substantially all of its net
investment income from each Portfolio, if any, together with any net realized
capital gains, after the close of the Fund's fiscal year. Any dividend or
capital gains distribution paid shortly after the purchase of shares by an
investor may have the effect of reducing the per share net asset value by the
per share amount of the dividend or distribution. Furthermore, such dividends or
distributions, although in effect a return of capital, are subject to income
taxes.
 
     Unless the shareholder elects otherwise, dividends and capital gain
distributions are paid in additional shares which are credited to the
shareholder's account. Any dividend and distribution election will remain in
effect until the Fund's Transfer Agent is notified by the shareholder in writing
or by calling Customer Service to change the election at least three days prior
to the record date. An account statement is sent to shareholders whenever an
income dividend or capital gains distribution is paid.
 
                             INVESTMENT LIMITATIONS
 
     Each Portfolio of the Fund is subject to the following restrictions which

of the voting securities present at a meeting if the holders of more than 50
percent of the outstanding voting securities of the Portfolio are present or
represented by proxy, or (ii) more than 50 percent of the outstanding voting
securities of the Portfolio. Each Portfolio will not:
 
          (1) make investments in commodities except that each Portfolio may
     invest in stock futures contracts, stock options, options on stock futures
     contracts and, in the case of the International Growth Portfolio foreign
     currency futures contracts and options, to the extent that not more than 5%
     of the Portfolio's assets are used as initial margin deposit at any time
     and not more than 20% of the Portfolio's assets are invested in futures
     contracts and/or options at any time;
 
          (2) make investments in real estate, although it may purchase and sell
     securities of companies which deal in real estate or interests therein;
 
          (3) each Portfolio of the Fund may lend its investment securities to
     qualified brokers, dealers, banks or other financial institutions, so long
     as the terms and the structure of such loans are not inconsistent with the
     Investment Company Act of 1940, as amended, or the Rules and Regulations or
     interpretations of the Securities and Exchange Commission thereunder, which
     currently require that (a) the borrower pledge and maintain with the
     Portfolio collateral consisting of cash, an
 
                                        7
<PAGE>   94
 
     irrevocable letter of credit or securities issued or guaranteed by the
     United States Government having a value at all times not less than 100
     percent 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 Portfolio at any time and (d) the Portfolio
     receive reasonable interest on the loan (which may include the Portfolio's
     investing any cash collateral in interest bearing short-term investments),
     and distributions on the loaned securities and any increase in their market
     value. Each Portfolio of the Fund will not lend securities if, as a result,
     the aggregate of such loans exceeds 33 1/3% of the value of the Portfolio's
     total assets. Loan arrangements made by the Fund will comply with all other
     applicable regulatory requirements, including the rules of the New York
     Stock Exchange, which rules presently require the borrower, after notice,
     to redeliver the securities within the normal settlement time of five
     business days;
 
          (4) engage in the business of underwriting securities issued by others
     except to the extent that a Portfolio may technically be deemed to be an
     underwriter under the Securities Act of 1933 in disposing of portfolio
     securities;
 
          (5) purchase securities on margin or make short sales except as
     described above in (1);
 
          (6) borrow except from banks and not in excess of the lesser of 10% of
     its gross assets taken at cost (before such borrowings) or 33 1/3% of its
     gross assets, less liabilities other than such borrowings, taken at market
     or other fair value, and any borrowing may be undertaken only as a
     temporary measure for extraordinary or emergency purposes to facilitate the
     meeting of redemption requests (not for leverage); or pledge, mortgage or
     hypothecate assets to an extent greater than 15% of the value of its gross
     assets, taken at cost (as a matter of policy each Portfolio will limit any
     such pledging, mortgaging or hypothecating to 10% of its assets);
 
          (7) invest for the purpose of exercising control over or management of
     any company;
 
          (8) invest in securities of other investment companies, except as may
     be acquired as a part of a merger, consolidation or acquisition of assets
     or otherwise to the extent permitted by Section 12 of the 1940 Act. A
     Portfolio will invest only in investment companies which have investment
     objectives and investment policies consistent with those of the Portfolio;
 
          (9) with respect to 75% of its assets, purchase securities of any
     issuer (except obligations of the United States government and its
     instrumentalities) if as a result the Fund would hold more than 10% of the
     voting securities of the issuer, or more than 5% of the value of the
     Portfolio's total assets would be invested in the securities of the issuer;
 
          (10) purchase or retain securities of an issuer if an officer or
     director of such issuer is an officer or director of the Fund or its
     investment adviser and one or more of such officers or directors of the
     Fund or its investment adviser owns beneficially more than 1/2% of the
     shares or securities of such issuer and all such directors and officers
     owning more than 1/2% of such shares or securities together own more than
     5% of such shares or securities;
 
   
          (11) purchase securities of any company which has (with predecessors)
     a record of less than three years' continuous operation if as a result more
     than 5% of the Portfolio's assets would be invested in securities of such
     companies; or
    
 
          (12) invest more than 25% of the value of its total assets in any one
     industry; and
 
          (13) purchase or otherwise acquire any security if, as a result more
     than 15% of its net assets would be invested in securities that are
     illiquid (this limitation applies to the Fund's investment in The Vanguard
     Group, Inc.).
 
     These investment limitations are considered at the time that investment
securities are purchased. Notwithstanding these limitations, the Fund 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
 
                                        8

owned by the Fund and one or more other investment companies and is primarily
engaged in the business of providing, at-cost, management, administrative or
related services to the Fund and other investment companies. See "Management of
the Fund."
 
     Although not fundamental policies subject to shareholder vote, as long as
the Fund's shares are registered for sale in certain states, a Portfolio will
not (i) invest in put, call, straddle or spread options, except as set forth
above in (1), (ii) invest in interests in oil, gas or other mineral exploration
or development programs, and (iii) pledge, mortgage or hypothecate assets to an
extent greater than 10% of the value of its net assets at market value.

THE VANGUARD GROUP
 
     Vanguard World Fund, Inc. is a member of The Vanguard Group of Investment
Companies. Through their jointly-owned subsidiary, The Vanguard Group, Inc.
("Vanguard"), the Fund and the other Funds in the Group obtain at-cost virtually
all of their corporate management, administrative and distribution services.
Vanguard also provides investment advisory services on an at-cost basis to
several of the Vanguard Funds.
 
   
     Vanguard employs a supporting staff of management and administrative
personnel needed to provide the requisite services, 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. In order to generate additional revenues for
Vanguard and thereby reduce the Funds' expenses, Vanguard also provides certain
administrative services to other organizations.
    
 
     The Fund's officers are also officers and employees of Vanguard. No officer
or employee owns, or is permitted to own, any securities of any external adviser
for the Funds.
 
   
     The Vanguard Group adheres to a Code of Ethics established pursuant to Rule
17j-l under the Investment Company Act of 1940. The Code is designed to prevent
unlawful practices in connection with the purchase or sale of securities by
persons associated with Vanguard. Under Vanguard's Code of Ethics certain
officers and employees of Vanguard who are considered access persons are
permitted to engage in personal securities transactions. However, such
transactions are subject to procedures and guidelines substantially similar to
those recommended by the mutual fund industry and approved by the U.S.
Securities and Exchange Commission.
    
 
   
     Vanguard 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 relative net assets
and its contribution to Vanguard's capital. At August 31, 1995, the Fund had
contributed capital of $823,000 to Vanguard, representing 4.1% of Vanguard's
capitalization. The Funds' Service Agreement provides as follows: (a) each
Vanguard Fund may invest up to .40% of its current assets in Vanguard, and (b)
there is no other limitation on the amount each Vanguard Fund may contribute to
Vanguard's capitalization.
    
 
   
     MANAGEMENT  Corporate management and administrative services include: (1)
executive staff; (2) accounting and financial; (3) legal and regulatory; (4)
shareholder account maintenance; (5) monitoring and control of custodian
relationships; (6) shareholder reporting; and (7) review and evaluation of
advisory and other services provided to the Funds by third parties. During the
fiscal year ended August 31, 1995, the Fund's allocated share of Vanguard's
actual net costs of operation relating to management and administrative services
(including transfer agency) totaled approximately $15,724,000.
    
 
     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 the shares of
the Funds, in connection with any sales made directly to investors in the states
of Florida, Missouri, New York, Ohio, Texas and such other states as it may be
required.
 
     The principal distribution expenses are for advertising, promotional
materials and marketing personnel. Distribution services may also include
organizing and offering to the public, from time to time, one or more new
investment companies which will become members of the Group. The Directors and
Officers of Vanguard determine the amount to be spent annually on distribution
activities, the manner and amount to be spent on each Fund, and whether to
organize new investment companies.
 
     One half of the distribution expenses of a marketing and promotional nature
is allocated among the Funds based upon relative net assets. The remaining one
half of those 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
 
                                       10
<PAGE>   97
 
   
as a Group, provided, however, that no Fund's aggregate quarterly rate of
contribution for distribution expenses of a marketing and promotional nature
shall exceed 125% of the average distribution expense rate for the Group, and
that no Fund shall incur annual distribution expenses in excess of 20/100 of 1%
of its average month-end net assets. During the fiscal year ended August 31,
1995, the Fund paid approximately $1,144,000 of the Group's distribution and
marketing expenses, which represented an effective annual rate of .02% of 1% of
the Fund's average net assets.
    
 
   
     INVESTMENT ADVISORY SERVICES  Vanguard also provides investment advisory
services to Vanguard Municipal Bond Fund, Vanguard California Tax-Free Fund,
Vanguard New Jersey Tax-Free Fund, Vanguard New York Insured Tax-Free Fund,
Vanguard Pennsylvania Tax-Free Fund, Vanguard Ohio Tax-Free Fund, Vanguard
Florida Insured Tax-Free Fund, Vanguard Admiral Funds, Vanguard Bond Index Fund,
Vanguard Index Trust, Vanguard International Equity Index Fund, Vanguard
Balanced Index Fund, the Money Market, High-Grade Bond, and Equity Index
Portfolios of Vanguard Variable Insurance Fund,Vanguard Money Market Reserves,
Vanguard Institutional Portfolios, several portfolios of Vanguard Fixed Income
Securities Fund, Vanguard Tax-Managed Fund, the Aggressive Growth Portfolio of
Vanguard Horizon Fund, a portion of Vanguard/Windsor, a portion of
Vanguard/Morgan Growth Fund as well as several indexed separate accounts. These
services are provided on an at-cost basis from a money 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 Fund pays each Director, who is
not also an Officer, an annual fee plus travel and other expenses incurred in
attending Board meetings. The Fund's officers and employees are paid by Vanguard
which, in turn, is reimbursed by the Fund and each other Fund in the Group, for
its allocated share of Officers' and employees' salaries and retirement
benefits. The Fund's proportionate share of remuneration paid by Vanguard (and
reimbursed by the Fund) during the 1995 fiscal year to all Officers of the Fund,
as a group, was approximately $ -- .
    
 
   
     Directors who are not Officers are paid an annual fee based on the number
of years of service on the Board upon retirement. The fee is equal to $1,000 for
each year of service (up to fifteen years) and each investment company member of
the Vanguard Group contributes a proportionate amount to this fee based on its
relative net assets. Under its retirement plan, Vanguard contributes annually an
amount equal to 10% of each eligible officer's annual compensation plus 5.7% of
that part of an eligible officer's compensation during the year, if any, that
exceeds the Social Security Taxable Wage Base then in effect. Under its thrift
plan, all eligible officers are permitted to make pre-tax contributions in an
amount up to 4% of total compensation, subject to federal tax limitations, which
are matched by Vanguard on a 100% basis. The Fund's proportionate share of
retirement contributions made by Vanguard under its retirement and thrift plans
on behalf of all Officers of the Fund, as a group, during the 1995 fiscal year
was approximately $ -- .

THE U.S. GROWTH PORTFOLIO INVESTMENT ADVISORY AGREEMENT
 
     The Fund entered into an investment advisory agreement with Lincoln Capital
Management Company (Lincoln) as of April 1, 1993, under which Lincoln manages
the investment and reinvestment of the assets included in the Fund's U.S. Growth
Portfolio and continuously reviews, supervises and administers the Fund's U.S.
Growth Portfolio. Lincoln will invest or reinvest such assets primarily in U.S.
securities. Lincoln discharges its responsibilities subject to the control of
the Officers and Directors of the Fund. Under this agreement the Fund pays
Lincoln an advisory fee at the end of each fiscal quarter, calculated by
applying a quarterly rate, based on the following annual percentage rates, to
the Portfolio's average month-end net assets for the quarter:

DESCRIPTION OF LINCOLN
 
     Lincoln is an Illinois corporation in which a controlling interest is held
by the following persons: John W. Croghan, Chairman; J. Parker Hall III,
President; Kenneth R. Meyer, Executive Vice President; and Timothy H. Ubben,
Executive Vice President.
 
     Because Lincoln provides only investment advisory services to the Fund and
has no control over the Fund's expenses, Lincoln has not undertaken to guarantee
expenses of the Fund. The Officers of the Fund have worked out alternative
arrangements with the state authorities which do not require an expense
guarantee.
 
   
     The agreement with Lincoln continues until March 31, 1996. The agreement is
renewable thereafter, for successive one-year periods, only if each renewal is
specifically approved by a vote of the Fund's Board of Directors, including the
affirmative votes of a majority of the directors who are not parties to the
agreement or "interested persons" (as defined in the Investment Company Act of
1940) of any such party, cast in person at a meeting called for the purpose of
considering such approval. The agreement is automatically terminated if
assigned, and may be terminated without penalty at any time (1) by vote of the
Board of Directors of the Portfolio on sixty (60) days' written notice to
Lincoln, or (2) by Lincoln upon ninety (90) days' written notice to the Fund.
    
 
     The Directors may make any of these changes without the approval of
shareholders, however, shareholders will receive 30 days' advance written notice
of any such changes.
 
THE INTERNATIONAL GROWTH PORTFOLIO INVESTMENT ADVISORY AGREEMENT
 
   
     The Fund has entered into an investment advisory agreement dated as of
April 1, 1993 with Schroder Capital Management, Inc. ("Schroder Capital") under
which Schroder Capital, through its Schroder Capital Management International,
London, England branch, supervises and administers the International Growth
Portfolio's investment program. In this regard, it is the responsibility of
Schroder Capital to make decisions relating to the International Growth
Portfolio's investment in foreign securities and to place the International
Growth Portfolio's purchase and sale orders for such securities. Schroder
Capital will invest or reinvest the assets of the International Growth Portfolio
only in foreign (non-U.S.) securities. Schroder Capital discharges its
responsibilities subject to the control of the Officers and Directors of the
Fund.
    
 
     As compensation for the services rendered by Schroder Capital under the
agreement, the Fund pays Schroder Capital a Basic Fee calculated by applying a
quarterly rate, based on the following annual percentage rates, to the average
value of the month-end net assets of the International Growth Portfolio for the
quarter:

     The Basic Fee, as provided above, shall be increased or decreased by
applying an adjustment formula based on the investment performance of the
International Growth Portfolio relative to that of the Morgan Stanley Capital
Europe, Australia, Far East Index ("EAFE") as follows:
 
     (a) On assets of the Portfolio of $1 billion or less:

                 -12% or below...........................         -0.0500%
</TABLE>
 
     The incentive/penalty fee adjustment for assets in excess of $1 billion
will not be fully operable until the quarter ending February 29, 1996, and,
until that date, will be calculated according to certain transition rules. From
April 1, 1993 through November 30, 1993, the incentive/penalty fee on assets in
excess of $1 billion was not operable. For quarters ending after this period,
the incentive/penalty fee adjustment on assets in excess of $1 billion will be
computed based on a comparison of the investment performance of the Portfolio
and that of the EAFE Index over the number of months that have elapsed between
March 1, 1993 and the end of the quarter for which the fee is computed.
 
     For the purpose of determining the fee adjustment for investment
performance, as described above, the net assets of the International Growth
Portfolio are averaged over the same period as the investment performance of the
International Growth Portfolio and the investment record of the EAFE Index are
computed.
 
     The investment performance of the International Growth Portfolio for such
period, expressed as a percentage of the net asset value per share of the
International Growth Portfolio at the beginning of such period, shall be the sum
of: (i) the change in the net asset value per share of the International Growth
Portfolio during such period; (ii) the value of the cash distributions per share
of the International Growth Portfolio accumulated to the end of such period; and
(iii) the value of capital gains taxes per share paid or payable by the
International Growth Portfolio on undistributed realized long-term capital gains
accumulated to the end of such period. For this purpose, the value of
distributions per share of realized capital gains, of dividends per share paid
from investment income and of capital gains taxes per share paid or payable on
undistributed realized long-term capital gains shall be treated as reinvested in
shares of the International Growth Portfolio at the net asset value per share in
effect at the close of business on the record date for the payment of such
distributions and dividends and the date on which provision is made for such
taxes, after giving effect to such distributions, dividends and taxes. The
investment record of the EAFE Index for any period, expressed as a percentage of
the EAFE Index level at the beginning of such period, shall be the sum of (i)
the change in the level of the EAFE Index during such period and (ii) the value,
computed consistently with the EAFE Index, of cash distributions made by
companies whose securities comprise the EAFE Index accumulated to the end of
such period. For this purpose cash distributions on the securities which
comprise the EAFE Index shall be treated as reinvested in the EAFE Index at
least as frequently as the end of each calendar quarter following the payment of
the dividend.
 
                                       14
<PAGE>   101
 
The foregoing notwithstanding, any computation of the investment performance of
the International Growth Portfolio and the investment record of the EAFE Index
shall be in accordance with any then applicable rules of the Securities and
Exchange Commission.
 
     The Directors believe that the EAFE Index is an appropriate standard
against which the investment performance of the Fund's International Growth
Portfolio can be measured. The EAFE Index is the only index available which
covers the major international markets outside North America. The weighting of
securities in the EAFE Index is based on each stock's relative total market
value, that is, its market price per share times the number of shares
outstanding.
 
   
     The agreement with Schroder Capital continues until March 31, 1996. The
agreement may be terminated prior to that date, or continued after March 31,
1996, in accordance with the same provisions applicable to the Fund's agreement
with Lincoln.
    
 
   
     During the three fiscal years ending August 31, 1993, 1994 and 1995,
respectively, the Fund paid Schroder Capital the following advisory fees:

DESCRIPTION OF SCHRODER CAPITAL
 
     Schroder Capital Management International ("Schroder Capital"), is the
London branch office of Schroder Capital. Schroder Capital is a wholly-owned
subsidiary of Schroders Incorporated, One State Street, New York, New York.
 
     Schroders PLC is the holding company parent of a large world-wide group of
banks and financial service companies (referred to as "The Schroder Group") with
associated companies and branch and representative offices located in seventeen
countries.
 
   
     The Schroder Group specializes in providing investment management services,
with Group funds under management currently in excess of $102 billion. Schroder
Capital Management International was established in London in 1979 to manage
international portfolios for U.S. institutions.

<PAGE>   102
 
                             PORTFOLIO TRANSACTIONS
 
     The investment advisory agreements with Lincoln and Schroder Capital
authorize the investment advisers (with the approval of the Fund's Board of
Directors) to select the brokers or dealers that will execute the purchases and
sales of portfolio securities for the Fund and direct each investment adviser to
use its best efforts to obtain the best available price and most favorable
execution with respect to all transactions for each Portfolio of the Fund. Each
investment adviser has undertaken to execute each investment transaction at a
price and commission which provides the most favorable total cost or proceeds
reasonably obtainable under the circumstances.
 
   
     In placing portfolio transactions, each investment adviser will use its
best judgment to choose the broker most capable of providing the brokerage
services necessary to obtain best available price and most favorable execution.
The full range and quality of brokerage services available will be considered in
making these determinations. In those instances where it is reasonably
determined that more than one broker can offer the brokerage services needed to
obtain the best available price and most favorable execution, consideration may
be given to those brokers which supply investment research statistical
information, and provide other services in addition to execution services to the
Portfolios and/or the investment adviser. Each investment adviser considers the
investment services it receives 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 Fund's Board of Directors, each investment adviser may cause the
Fund to pay a broker-dealer which furnishes brokerage and research services a
higher commission than that which might be charged by another broker-dealer for
effecting the same transaction; provided that such commission is deemed
reasonable in terms of either that particular transaction or the overall
responsibilities of the investment adviser to the Fund and the other Funds in
the Group.
 
     Currently, it is the Fund's policy that each investment adviser may at
times pay higher commissions in recognition of brokerage services felt necessary
for the achievement of better execution of certain securities transactions than
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
Portfolio. Some brokers or dealers who may receive such higher commissions in
recognition of brokerage services related to execution of securities
transactions are also providers of research information to the investment
adviser and/or the Portfolios. However, the investment adviser has informed the
Fund that it will not pay higher commission rates specifically for the purpose
of obtaining research services.
 
     The Fund's Board of Directors has authorized Schroder Capital to utilize
Schroders Asia Limited, an affiliated company 75% owned by the Schroder Group,
in the capacity of broker in connection with the execution of the International
Growth Portfolio transactions in Hong Kong securities; provided, however, that
Schroder Capital believes that doing so will result in an economic advantage (in
the form of lower execution costs or otherwise) being obtained for the
Portfolio. This authorization was made in accordance with Section 17(e) of the
Investment Company Act of 1940 and Rule 17e-1 which require the Fund's
non-interested Directors to approve the procedures under which such brokerage
allocation is to be made and to monitor such allocations on a continuing basis.
Except with respect to tender offers, it is not expected that any portion of the
commissions, fees, brokerage, or similar payments received by Schroders Asia
Limited in such transactions will be recaptured by the Portfolio. The Directors
have reviewed and intend to continue to review whether other recapture
opportunities are legally permissible and available and, if they appear to be,
determine whether it would be advisable for the Portfolio to seek to take
advantage of them.
 
     Since the Fund does not market its shares through intermediary brokers or
dealers, it is not the Fund's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be made through such
firms. However, each Portfolio may place orders with qualified broker-dealers
who recommend the Fund and its Portfolios to clients, or who act as agent in the
purchase of shares of the
 
                                       16
<PAGE>   103
 
Fund for their clients, and may, when a number of brokers and dealers can
provide comparable best price and execution on a particular transaction,
consider the sale of Fund shares by a broker or dealer in selecting among
qualified broker-dealers.
 
   
     During the fiscal years ending August 31, 1993, 1994 and 1995 the Fund paid
$4,903,334, $6,863,785 and $6,681,209 in brokerage commissions, respectively.
    
 
     Some securities considered for investment by the Portfolios may also be
appropriate for other Funds or clients served by the investment advisers. If
purchase or sale of securities consistent with the investment policies of the
Portfolio and one or more of these other Funds or clients served by the
investment advisers are considered at or about the same time, transactions in
such securities will be allocated among the Portfolios and the several Funds and
clients in a manner deemed equitable by the respective investment adviser.
Although there will be no specified formula for allocating such transactions,
the allocation methods used, and the results of such allocations, will be
subject to periodic review by the Fund's Board of Directors.

ITEM 27. INDEMNIFICATION
 
     Reference is made to Article IX of Registrant's proposed Amended and

Insofar as indemnification for liability arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the
 
                                       C-1

securities being registered, the registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
