INVESTMENT
OBJECTIVE AND
POLICIES
                      Vanguard International Equity Index Fund, Inc. (the
                      "Fund") is an open-end diversified investment company
                      designed as an "index" fund. The Fund consists of three
                      portfolios, European, Pacific, and Emerging Markets
                      Portfolios, each of which invests in common stocks in
                      order to match the performance of a distinct international
                      market index. This prospectus pertains to the European and
                      Pacific Portfolios; the Emerging Markets Portfolio is
                      offered by a separate prospectus. The European Portfolio
                      seeks to provide investment results, using statistical
                      procedures, that parallel the Morgan Stanley Capital
                      International -- Europe (Free) Index, a diversified index
                      consisting of companies located in fourteen European
                      countries. The Pacific Portfolio seeks to provide
                      investment results, using statistical procedures, that
                      parallel the Morgan Stanley Capital
                      International -- Pacific (Free) Index, a diversified index
                      consisting of companies located in Japan, Australia, New
                      Zealand, Hong Kong, Singapore and Malaysia. The Portfolios
                      invest primarily in common stocks included in their
                      respective indexes. There is no assurance that either
                      Portfolio will achieve its stated objective. Shares of the
                      Fund are neither insured nor guaranteed by any agency of
                      the U.S. Government, including the FDIC.

                      would bear directly or indirectly as an investor in the
                      European and Pacific Portfolios.
 
EACH PORTFOLIO
CHARGES A 1%
TRANSACTION FEE       Each Portfolio assesses a portfolio transaction fee on
                      purchases of Portfolio shares equal to 1% of the dollar
                      amount invested. In both Portfolios, the Portfolio
                      transaction fee is paid to the respective Portfolio, not
                      to Vanguard. It is not a sales charge. The fee applies to
                      an initial investment in the Portfolio and all subsequent
                      purchases (including purchases made by exchange from
                      another Vanguard Fund or from the other Portfolio of the
                      Vanguard International Equity Index Fund), but not to
                      reinvested dividend or capital gains distributions. The
                      Portfolio transaction fee is deducted automatically from
                      the amount invested; it cannot be paid separately.
 
                      The purpose of the 1% transaction fee is to allocate
                      transaction costs associated with new purchases to
                      investors making those purchases, thus insulating existing
                      shareholders from those transaction costs. These costs
                      include: (1) brokerage costs; (2) market impact
                      costs -- i.e., the increase in market prices which may
                      result when the Portfolios purchase thinly traded stocks;
                      and (3) the effect of the "bid-ask" spread in
                      international markets.
 
                      The 1% fee represents Vanguard's estimate of the brokerage
                      and other transaction costs incurred by the Portfolios in
                      acquiring international stocks. Without the 1%
 
                                        2
<PAGE>   5
 
                      fee, each Portfolio would incur these costs directly,
                      resulting in reduced investment performance for all
                      shareholders of the Portfolio. With the 1% fee, the
                      transaction costs of acquiring additional international
                      stocks are borne not by all existing shareholders, but
                      only by those investors making additional purchases.
                      Because the purchaser, not the Portfolio, bears these
                      costs, the Portfolio is expected to track its benchmark
                      index more closely.
 
   
EACH PORTFOLIO WILL
CHARGE A $10 ACCOUNT
MAINTENANCE FEE       Each Portfolio assesses an annual account maintenance fee
                      of $10 for each shareholder account. The purpose of the
                      $10 fee is to allocate part of the costs of maintaining
                      shareholder accounts equally to all accounts. This fee,
                      which is paid directly by shareholders, is deducted from
                      the Fund's annual dividend. See "Dividends, Capital Gains
                      and Taxes" for more information on this fee. The $10 fee
                      amounts to 1.00% on a $1,000 investment in the Fund, and
                      0.33% on a $3,000 investment. This fee will be waived for
                      shareholders with an account balance of $10,000 or more.
    
 
                      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. The expenses include the 1%
                      portfolio transaction fee.

                      Included in these estimates are account maintenance fees

                      shown. The $10 annual account maintenance fee is a flat
                      charge which does not vary by the size of your investment.
                      Accordingly, for investments larger than $1,000, your
                      total expenses will be substantially lower in percentage
                      terms than this illustration implies.

YIELD AND TOTAL
RETURN                From time to time a Portfolio of the Fund may advertise
                      its yield and total return. Both yield and total return
                      figures are based on historical earnings and are not
                      intended to indicate future performance. The "total
                      return" of a 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 a Portfolio is calculated by dividing the net
                      investment income per share earned during a 30-day period
                      by the net asset value per share on the last day of the
                      period. Net investment income includes interest and
                      dividend income earned on a Portfolio's securities; it is
                      net of all expenses and all recurring and nonrecurring
                      charges that have been applied to all shareholder
                      accounts. The yield calculation assumes that the net
                      investment income earned over 30 days is compounded
                      monthly for six months and then annualized. Methods used
                      to calculate advertised yields are standardized for all
                      stock and bond mutual funds. However, these methods differ
                      from the accounting

                      methods used by the 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.

OBJECTIVE
EACH PORTFOLIO SEEKS
TO MATCH THE

PERFORMANCE OF ITS
RESPECTIVE INDEX      The European Portfolio seeks to replicate the aggregate
                      price and yield performance of the Morgan Stanley Capital
                      International -- Europe (Free) Index ("MSCI-Europe
                      (Free)"), a diversified, capitalization weighted index
                      comprised of companies located in fourteen European
                      countries. The Pacific Portfolio seeks to replicate the
                      aggregate price and yield performance of the Morgan
                      Stanley Capital International -- Pacific (Free) Index
                      ("MSCI -- Pacific"), a diversified, capitalization
                      weighted index consisting of companies located in
                      Australia, Japan, Hong Kong, New Zealand, Singapore and
                      Malaysia. There is no assurance that either Portfolio will
                      achieve its stated objective.
    
 
   
                      By holding the two Portfolios in appropriate proportions,
                      an investor may create an aggregate portfolio designed to
                      approximate the total return (income plus capital change)
                      of the Morgan Stanley Capital International -- Europe,
                      Australia and Far East (Free) Index ("EAFE Free"), a
                      broadly diversified international index consisting of more
                      than 1,000 equity securities of companies located outside
                      of the United States. As of December 31, 1994, the
                      MSCI -- Pacific (Free) Index represented approximately 55%
                      of the market capitalization of EAFE (Free), while the
                      MSCI -- Europe (Free) Index represented the remaining 45%.
    
 
                      The Fund is neither sponsored by nor affiliated with

INVESTMENT
POLICIES
BOTH PORTFOLIOS USE A
"PASSIVE" APPROACH TO
INVEST IN INTERNATIONAL
STOCKS                The European and Pacific Portfolios are not managed
                      according to traditional methods of "active" investment
                      management, which involve the buying and selling of
                      securities based upon economic, financial and market
                      analysis and investment judgment. Instead, the Portfolios,
                      utilizing a "passive" or indexing investment approach,
                      attempt to approximate the investment performance of their
                      respective indexes through statistical procedures. The
                      Fund is managed without regard to tax ramifications.
 
   
                      The European Portfolio invests in a statistically selected
                      sample of approximately 545 stocks included in the
                      MSCI -- Europe (Free) Index, an index of equity securities
                      of companies located in fourteen European countries. Three
                      countries, the United Kingdom, Germany and France,
                      dominate MSCI -- Europe (Free), with 35%, 14%, and 13% of
                      the market capitalization of the Index, respectively, as
                      of December 31, 1994. The 11 other countries are
                      individually much less significant to the Index and,
                      consequently, the Portfolio. The "Free" Index includes
                      only shares that U.S. investors are "free" to purchase.
    
 
   
                      The Pacific Portfolio invests in a statistically selected
                      sample of the more than 440 stocks included in the
                      MSCI -- Pacific (Free) Index, an index of equity
                      securities of Pacific Basin companies. The MSCI -- Pacific
                      (Free) Index is dominated by the Japanese stock market,
                      which represented 83% of the market capitalization of the
                      Index as of December 31, 1994.

                      The Portfolios are each expected to invest in
                      approximately 250 stocks or more. Stocks are selected for
                      inclusion in each Portfolio based on country, market
                      capitalization, industry weightings, and fundamental
                      characteristics such as return variability, earnings
                      valuation, and yield. Each Portfolio is constructed to
                      have aggregate investment characteristics similar to those
                      of its respective index. In order to parallel the
                      performance of its respective index, each Portfolio will
                      invest in each country in approximately the same
                      percentage as the country's weight in the index.
    
 
   
                      Each Portfolio's policy is to remain fully invested in
                      common stocks. Under normal circumstances at least 80% of
                      the assets of each Portfolio will be invested in stocks
                      that are represented in its respective index. Each
                      Portfolio may invest in certain short-term fixed income
                      securities such as cash reserves, although cash or cash
                      equivalents are normally expected to represent less than
                      1% of each Portfolio's assets. Each Portfolio may also
                      invest up to 50% of its assets in stock futures contracts,
                      options, and warrants in order to invest uncommitted cash
                      balances, maintain liquidity to meet shareholder
                      redemptions, or minimize trading costs. Any investment in
                      futures contracts, options, warrants, convertible
                      securities or swap agreements over 20% of each Portfolio's
                      assets would be made in emergency situations, for
                      short-term purposes.
    
 
                      The Portfolios will not invest in cash reserves, futures
                      contracts, options or warrants as part of a temporary
                      defensive strategy, such as lowering a Portfolio's
                      investment in common stocks, to protect against potential
                      stock market declines. The Portfolios intend to remain
                      fully invested, to the extent practicable, in a pool of
                      securities which will approximate the investment
                      characteristics of their respective indexes. The
                      Portfolios may also enter into forward foreign currency
                      exchange contracts in order to maintain the same currency
                      exposure as their respective indexes, but not as part of a
                      defensive strategy to protect against fluctuations in
                      exchange rates. See "Implementation of Policies" for a
                      description of these and other investment practices of the
                      Portfolios.
 
                      The investment objective and policies of the Fund are not
                      fundamental and so may be changed by the Board of
                      Directors without shareholder approval. However,
                      shareholders would be notified prior to a material change
                      in either.

INVESTMENT
RISKS                 As mutual funds investing in common stocks, the Portfolios
                      are subject to market risk -- i.e., the possibility that
                      stock prices will decline over short or even extended
                      periods. Both U.S. and foreign stock markets tend to be
                      cyclical, with periods when stock prices generally rise
                      and periods when stock prices generally decline.
 
   
INTERNATIONAL STOCKS

VOLATILITY THAN
U.S. STOCKS           Investments in foreign stock markets can be as volatile,
                      if not more volatile, than investments in U.S. markets. To
                      illustrate the volatility of foreign stock market returns
                      for the U.S. dollar-based investor, the following tables
                      set forth the extremes of foreign stock market returns, as
                      well as average annual returns, for the period from 1970
                      to 1994, as measured by the MSCI -- Europe and
                      MSCI-Pacific (Free) Indexes and as calculated for a U.S.
                      dollar investor. (The MSCI -- Europe Index, which includes
                      common stocks that U.S. investors cannot purchase, is

                      As shown, the MSCI -- Europe Index has provided annual
                      total returns, averaging +14.2% for all 10-year periods
                      from 1970-1994, and the MSCI -- Pacific (Free) Index has
                      provided annual total returns, averaging +18.0% during the
                      same periods. By comparison, the average annual total
                      return of U.S. stocks during this same period was +10.7%
                      (as measured by the Standard & Poor's 500 Composite Stock
                      Price Index). Note, however, that the period from 1970 to
                      1994 was a very favorable one for foreign stock market
                      investing. 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.
    
 
                      This table on international stock market returns should
                      not be viewed as a representation of future returns for
                      international stocks or the Portfolios of the Fund, as
                      historical performance may be a poor guide to future
                      returns, and the Indexes shown do not reflect "real world"
                      transaction costs and other expenses.
 
   
THE JAPANESE STOCK
MARKET IS A MAJOR
COMPONENT OF THE
PACIFIC INDEX         Investors should realize that Japanese securities
                      comprised 83% of the MSCI -- Pacific (Free) Index as of
                      December 31, 1994, and that therefore stocks of Japanese
                      companies will represent a correspondingly large component
                      of the Pacific Portfolio's investment assets. Such a large
                      investment in the Japanese stock market may entail a
                      higher degree of risk than with more diversified
                      international portfolios, especially considering that by
                      fundamental measures of corporate valuation, such as its
                      high price-earnings ratios and low dividend yields, the
                      Japanese market as a whole may appear expensive relative
                      to other world stock markets.
    
 
   
STOCKS FROM THREE
COUNTRIES DOMINATE
THE EUROPE (FREE)
INDEX                 Stocks from the United Kingdom, Germany and France
                      comprised 35%, 14% and 13% of the MSCI -- Europe (Free)
                      Index, respectively, as of December 31, 1994. The
                      remaining 11 countries in the MSCI -- Europe (Free) Index
                      have much less significant capitalization weightings in
                      the Index and will therefore have much less impact on the
                      total return of the Index and the European Portfolio.

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 two Portfolios, are influenced
                      by not only the returns on foreign common stocks
                      themselves, but also by the returns on the currencies in
                      which the stocks are denominated. Currency risk is the
                      risk that changes in foreign exchange rates will affect,
                      favorably or unfavorably, the value of foreign securities
                      held by a Portfolio. In a period when the U.S. dollar
                      generally rises against foreign currencies, the returns on
                      foreign stocks for a U.S. investor will be diminished. By
                      contrast, in a period when the U.S. dollar generally
                      declines, the returns on foreign stocks will be enhanced.
 
                      Other risks and considerations of international investing
                      include: differences in accounting, auditing and financial
                      reporting standards; generally higher transaction costs on
                      foreign portfolio transactions; small trading volumes and
                      generally lower liquidity of foreign stock markets, which
                      may result in greater price volatility; foreign
                      withholding taxes payable on a Portfolio's foreign
                      securities, which may reduce dividend income payable to
                      shareholders; the possibility of expropriation or
                      confiscatory taxation; adverse change in investment or
                      exchange control regulations; difficulty in obtaining a
                      judgement from a foreign court; political instability
                      which could affect U.S. investment in foreign countries;
                      and potential restriction on the flow of international
                      capital.

COMMON STOCKS         The Portfolios are designed for investors who seek a
                      low-cost "passive" approach for investing in a broadly
                      diversified portfolio of international common stocks.
                      Unlike other equity mutual funds, which generally seek to
                      "beat" market averages with often unpredictable results,
                      the Portfolios of the Fund seek to "match" their
                      respective indexes and thus are expected to provide a
                      predictable return relative to their respective
                      benchmarks. In particular, the European Portfolio is
                      designed for investors seeking to approximate the total
                      investment results (before fund expenses and withholding
                      taxes) of the MSCI -- Europe (Free) Index, a diversified
                      index of European common stocks. The Pacific Portfolio is
                      designed for investors seeking to approximate the total
                      investment results (before fund expenses and withholding
                      taxes) of the MSCI -- Pacific (Free) Index, a diversified
                      index of Pacific Basin common stocks.
    
 
   
                      The Portfolios are also suitable for investors seeking to
                      create a portfolio which parallels the performance of the
                      MSCI -- EAFE (Free) Index, a broadly diversified index
                      consisting of over 1,000 international equity securities.
                      By investing in the two portfolios in the appropriate
                      percentages (55% in the Pacific Portfolio and 45% in the
                      European Portfolio as of December 31, 1994), a portfolio
                      approximating the investment characteristics of EAFE
                      (Free) may be created.
    
 
                      The share prices of the Portfolios are expected to be
                      volatile, and investors should be able to tolerate sudden,
                      sometimes substantial fluctuations in the value of their
                      investment. No assurance can be given that a Portfolio
                      will achieve its stated objective or that shareholders
                      will be protected from the risks inherent in equity
                      investing. Investors may wish to minimize the timing risk
                      of investing in a Portfolio by purchasing shares on a
                      periodic basis (dollar-cost averaging) rather than
                      investing in one lump sum.

                      Because of the risks associated with international common
                      stock investments, the Fund is intended to be a long-term
                      investment vehicle and is not designed to provide
                      investors with a means of speculating on short-term market
                      movements. 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 Portfolios have adopted the following policies.
                      The Portfolios reserve 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 Portfolios have adopted
                      exchange privilege limitations as described in the section
                      "Exchange Privilege Limitations." Finally, the Portfolios
                      reserve the right to suspend the offering of its shares.
                      Investors should not consider the Portfolios a complete
                      investment program, but should maintain holdings of
                      securities with different risk characteristics --
                      including U.S. common stocks, bonds and money market 
                      instruments.

IMPLEMENTATION
OF POLICIES
THE PORTFOLIOS INVEST
IN INTERNATIONAL
COMMON STOCKS USING
SAMPLING TECHNIQUES   The Portfolios utilize a number of investment practices in
                      an effort to parallel the investment performance of their
                      respective indexes.
 
   
                      The MSCI -- Europe (Free) Index consists of approximately
                      590 equity securities from Europe, and the MSCI -- Pacific
                      (Free) Index consists of more than 520 equity securities
                      from Australia and the Far East. The stocks included in
                      each index are chosen by Morgan Stanley Capital
                      International on a statistical basis. Each stock in
                      MSCI -- Europe (Free) and MSCI -- Pacific (Free) is
                      weighted according to its market value as a percentage of
                      the total market value of all stocks in the index. (A
                      stock's market value equals the number of shares
                      outstanding times the most recent price of the security.)
                      The inclusion of a stock in the index in no way implies
                      that Morgan Stanley Capital International believes the
                      stock to be an attractive investment.
    
 
                      The Portfolios will be unable to hold all of the issues
                      that comprise their respective indexes because of the
                      costs involved and the illiquidity of many of the
                      securities. Instead, each Portfolio will attempt to hold a
                      representative sample of approximately 250 or more of the
                      securities in its respective Index, which will be selected
                      utilizing a statistical technique known as "portfolio
                      optimization." Under this technique, each stock is
                      considered for inclusion in the Portfolio based on its
                      contribution to certain country, capitalization, industry,
                      and fundamental investment characteristics. Each Portfolio
                      is constructed so that, in the aggregate, each Portfolio's
                      country, capitalization, industry, and fundamental
                      investment characteristics resemble those of its
                      respective Index. Over time, portfolio composition is
                      altered (or "rebalanced") to reflect changes in the
                      characteristics of the Indexes.
 
                      Due to the use of this sampling or "portfolio
                      optimization" technique, the Portfolios are not expected
                      to track their benchmark indexes with the same degree of
                      accuracy as large capitalization domestic index funds.
                      Over time, the correlation between the performance of each
                      Portfolio and its respective index is expected to be
                      greater than 0.95. A correlation of 1.00 would indicate
                      perfect correlation, which would be achieved when the net
                      asset value of each Portfolio, including the value of its
 
                                       10
<PAGE>   13
 
                      dividend and capital gains distributions, increases or
                      decreases in exact proportion to changes in its respective
                      index.
 
   
EACH PORTFOLIO MAY
INVEST IN SHORT-TERM
FIXED INCOME
SECURITIES            Although each Portfolio's policy is to remain
                      substantially fully invested in common stocks, the two
                      Portfolios may invest temporarily in certain short-term
                      fixed income securities. Such securities may be used to
                      invest uncommitted cash balances or to maintain liquidity
                      to meet shareholder redemptions. These securities include:
                      obligations of the United States Government and its
                      agencies or instrumentalities; commercial paper (rated
                      Prime-1 by Moody's Investors Services, Inc. or A-1 by
                      Standard & Poor's Corporation), bank certificates of
                      deposit and bankers' acceptances; and repurchase
                      agreements collateralized by these securities.
    
 
EACH PORTFOLIO MAY
USE FUTURES CONTRACTS,
OPTIONS AND WARRANTS,
CONVERTIBLE SECURITIES
AND SWAP AGREEMENTS   The Portfolios may utilize stock futures contracts,
                      options, warrants, convertible securities and swap
                      agreements to a limited extent. Specifically, each
                      Portfolio may enter into futures contracts and options
                      provided that not more than 5% of its assets are required
                      as a margin deposit for futures contracts or options.
                      Additionally, the Fund's investment in warrants will not
                      exceed more than 5% of its assets (2% with respect to
                      warrants not listed on the New York or American Stock
                      Exchanges). Futures contracts, options, warrants,
                      convertible securities and swap agreements may be used for
                      several reasons: to simulate full investment in the
                      underlying index while retaining a cash balance for fund
                      management purposes, to facilitate trading, to reduce
                      transaction costs or to seek higher investment returns
                      when a futures contract, option, warrant, convertible
                      security or swap agreement is priced more attractively
                      than the underlying equity security or index. While each
                      of these securities can be used as leveraged investments,
                      the Portfolios may not use them to leverage its net
                      assets.
 
FUTURES CONTRACTS,
OPTIONS, WARRANTS,
CONVERTIBLE SECURITIES
AND SWAP AGREEMENTS
POSE CERTAIN RISKS    The risk of loss associated with 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 an immediate and substantial loss or gain.
                      However, the Portfolios will not use futures contracts,
                      options, warrants, convertible securities and swap
                      agreements for speculative purposes or to leverage their
                      net assets. Accordingly, the primary risks associated with
                      the use of futures contracts, options, warrants,
                      convertible securities and swap agreements by the
                      Portfolios are: (i) imperfect correlation between the
                      change in market value of the stocks held by a Portfolio
                      and the prices of futures contracts, options, warrants,
                      convertible securities and swap agreements; 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 a
                      Portfolio's underlying securities. The risk that a
                      Portfolio will be unable to close out a futures position
                      will be minimized by entering into such transactions on an
                      exchange with an active and liquid secondary market.
                      However options, warrants, convertible securities and swap
                      agreements purchased or sold over-the-counter may be less
                      liquid than exchange traded securities. Illiquid
 
                                       11
<PAGE>   14
 
                      securities, in general, including swap agreements, may not
                      represent more than 15% of the net assets of a Portfolio
                      of the Fund.
 
   
                      Since there are no futures traded on the MSCI -- Europe
                      (Free) or Pacific (Free) Index, it will be necessary for
                      the Portfolio to utilize a composite of other futures
                      contracts to simulate the performance of the Indexes. This
                      process may magnify the "tracking error" of a Portfolio's
                      performance compared to that of its Index, due to lower
                      correlation of the selected futures with its Index. The
                      investment adviser will attempt to reduce this tracking
                      error by investing in futures contracts whose behavior is
                      expected to resemble that of the underlying securities,
                      although there can be no assurance that these selected
                      futures will perfectly correlate with the performance of
                      either Index.
    
 
                      Swap agreements are contracts between parties in which one
                      party agrees to make payments to the other party based on
                      the change in market value of a specified index or asset.
                      In return, the other party agrees to make payments to the
                      first party based on the return of a different specified
                      index or asset. Although swap agreements entail the risk
                      that a party will default on its payment obligations
                      thereunder, the Portfolios will minimize this risk by
                      entering into agreements that mark to market no less
                      frequently than quarterly. Swap agreements also bear the
                      risk that the Portfolios will not be able to meet its
                      obligation to the counterparty. This risk will be
                      mitigated by investing the Portfolios in the specific
                      asset for which it is obligated to pay a return.
 
EACH PORTFOLIO MAY
ENTER INTO FORWARD
CURRENCY CONTRACTS    Each Portfolio may enter into foreign currency forward and
                      foreign currency futures contracts in order to maintain
                      the same currency exposure as their respective indexes. A
                      Portfolio may not enter into such contracts for
                      speculative purposes, or as a way of protecting against
                      anticipated adverse changes in exchange rates between
                      foreign currencies and the U.S. dollar. A foreign currency
                      forward 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.
 
EACH PORTFOLIO MAY
LEND ITS SECURITIES   Each Portfolio may lend its investment securities to
                      qualified institutional investors for either short-term or
                      long-term purposes of realizing additional income. Loans
                      of securities by the Portfolios will be collateralized by
                      cash, letters of credit, or securities issued or
                      guaranteed by the U.S. Government or its agencies. The
                      collateral will equal at least 100% of the current market
                      value of the loaned securities.
 
PORTFOLIO TURNOVER IS
EXPECTED TO BE LOW    Although the Portfolios generally seek to invest for the
                      long term, the Portfolios retain the right to sell
                      securities irrespective of how long they have been held.
                      However, because of the "passive" investment management
                      approach of the Fund, the portfolio turnover rate for each
                      Portfolio is expected to be under 50%, a generally lower
                      turnover rate than for most other investment companies. A
                      portfolio turnover rate of 50% would occur if one half of
                      a Portfolio's securities were sold within one year.
                      Ordinarily, securities will be sold from a Portfolio only
                      to reflect certain administrative changes in an index
                      (including mergers or changes in the composi-
 
                                       12
<PAGE>   15
 
                      tion of an index) or to accommodate cash flows out of the
                      Portfolio while maintaining the similarity of the
                      Portfolio to its benchmark index.
 
EACH PORTFOLIO MAY
BORROW MONEY          Each Portfolio may borrow money from a bank up to a limit
                      of 15% of the market value of its assets, but only for
                      temporary or emergency purposes. A Portfolio may borrow
                      money only to meet redemption requests prior to the
                      settlement of securities already sold or in the process of
                      being sold by the Portfolio. To the extent that a
                      Portfolio borrows money prior to selling securities, the
                      Portfolio may be leveraged; at such times, the Portfolio
                      may appreciate or depreciate in value more rapidly than
                      its benchmark index. Both Portfolios will repay any money
                      borrowed in excess of 5% of the market value of their
                      total assets prior to purchasing additional portfolio
                      securities.

INVESTMENT
LIMITATIONS
THE FUND HAS ADOPTED
CERTAIN FUNDAMENTAL
LIMITATIONS           Each Portfolio has adopted certain limitations on its
                      investment practices. Specifically, each Portfolio will
                      not:
 
                      (a) with respect to 75% of its assets, purchase securities
                          of any issuer (except obligations of the U.S.
                          Government and its instrumentalities) if, as a result,
                          more than 5% of the value of the Portfolio's assets
                          would be invested in the securities of such issuer;
                      (b) purchase more than 10% of the voting securities of any
                          issuer;
                      (c) invest more than 25% of its assets in any one
                          industry; and
                      (d) borrow money except from banks for temporary or
                          emergency purposes and in no event in excess of 15% of
                          the market value of its total assets.
 
                      These investment limitations are considered at the time
                      investment securities are purchased. The limitations
                      described here and in the Statement of Additional
                      Information may be changed only with the approval of a
                      majority of the Fund's shareholders.

MANAGEMENT OF
THE FUND
VANGUARD ADMINISTERS
AND DISTRIBUTES
THE FUND              The Portfolios are two of three Portfolios of Vanguard
                      International Equity Index Fund. The Fund is a member of
                      The Vanguard Group of Investment Companies, a family of
                      more than 30 investment companies with more than 80
                      distinct investment portfolios and total assets in excess
                      of $130 billion. Through their jointly-owned subsidiary,
                      The Vanguard Group, Inc. ("Vanguard"), the Fund and the
                      other funds in the Group obtain at cost virtually all of
                      their corporate management, administrative and
                      distribution services. Vanguard also provides investment
                      advisory services on an at-cost basis to certain Vanguard
                      funds. As a result of Vanguard's unique corporate
                      structure, the Vanguard funds have costs substantially
                      lower than those of most competing mutual funds. In 1994,
                      the average expense ratio (annual costs including advisory
                      fees divided by total net assets) for the Vanguard funds
                      amounted to approximately .30% compared to an average of
                      1.05% for the mutual fund industry (data provided by
                      Lipper Analytical Services).
    
 
                      The Officers of the Fund manage its day-to-day operations
                      and are responsible to the Fund's Board of Directors. The
                      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 to provide the requisite services
                      to the funds and also furnishes the funds with necessary
                      office space, furnishings and equipment. Each fund pays
                      its share of Vanguard's net expenses, which are allocated
                      among the funds under methods approved by the Board of
                      Directors (Trustees) of each fund. In addition, each fund
                      bears its own direct expenses, such as legal, auditing and
                      custodian fees.
 
                      Vanguard provides distribution and marketing services to
                      the funds. The funds are available on a no-load basis
                      (i.e., there are no sales commissions or 12b-1 fees).
                      However, each fund bears its own share of the Group's
                      distribution costs.

INVESTMENT
ADVISER
VANGUARD MANAGES
THE FUND ON AN
AT-COST BASIS         The Fund receives all investment advisory services on an
                      at-cost basis from Vanguard's Core Management Group, which
                      also provides investment advisory services to Vanguard
                      Index Trust, Vanguard Balanced Index Fund, Vanguard
                      Institutional Index Fund, a portion of the assets of
                      Vanguard/Windsor II and Vanguard Morgan Growth Fund, the
                      Equity Index Portfolio of Vanguard Variable Insurance
                      Fund, Vanguard Tax-Managed Fund, and several indexed
                      separate accounts. Total indexed assets under management
                      as of December 31, 1994 were $18.0 billion. The Portfolios
                      of the Fund are not actively managed, but are instead
                      administered by the Core Management Group using
                      computerized, quantitative techniques. The Group is
                      supervised by the Officers of the Fund.
    
 
                      In placing portfolio transactions, Vanguard's Core
                      Management Group uses its best judgment to choose the
                      broker most capable of providing the brokerage services
                      necessary to obtain the best available price and most
                      favorable execution at the lowest commission rate. The
                      full range and quality of brokerage services available are
                      considered in making these determinations. In those
                      instances where it is reasonably determined that more than
                      one broker can offer the services needed to obtain the
                      best available price and most favorable execution,
                      consideration may be given to those brokers which supply
                      statistical information and provide other services in
                      addition to execution services to the Fund.

DIVIDENDS,
CAPITAL GAINS
AND TAXES
DIVIDENDS AND ANY
CAPITAL GAINS WILL BE
PAID ANNUALLY         Each Portfolio intends to distribute substantially all of
                      its ordinary income in the form of dividends. The
                      Portfolios pay annual dividends. Capital gains
                      distributions, if any, are also made annually.
 
                      Each Portfolio's dividend and capital gains distributions
                      may be reinvested in additional shares 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, each Portfolio may declare
                      special year-end dividend and capital gain distributions
                      during December. Such distributions, if received by
                      shareholders by January 31, are deemed to have been paid
                      by each Portfolio and received by shareholders on December
                      31 of the prior year.

EACH PORTFOLIO WILL
CHARGE A $10 ACCOUNT
MAINTENANCE FEE       Each Portfolio will automatically deduct a $10 annual
                      account maintenance fee from the dividend income of each
                      Portfolio account on an annual basis. If the dividend to
                      be paid to an account is less than the fee to be deducted,
                      sufficient shares will be redeemed from an account to make
                      up the difference. The Board of Directors reserves the
                      right to change the annual account maintenance fee to
                      reflect the actual cost of maintaining smaller shareholder
                      accounts. For federal tax purposes, the account
                      maintenance fee does not reduce dividend income and is
                      treated as an investment expense by each shareholder
                      (deductible as a miscellaneous itemized deduction in the
                      case of individual investors). This fee will be waived for
                      shareholders with an account balance of $10,000 or more.
    
 
   
                      Each 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 each Portfolio from net
                      investment income and net short-term capital gains,
                      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 not generally qualify for the
                      intercorporate dividends-received deduction.
    
 
   
                      Distributions paid by a Portfolio from long-term capital
                      gains, whether received in cash or reinvested in
                      additional shares, are taxable as long-term capital gains,
                      regardless of the length of time you have owned shares in
                      a Portfolio. Capital gains distributions are made when a
                      Portfolio realizes net capital gains on sales of portfolio
                      securities during the year. A 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 a 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 a Portfolio. Also, keep in mind that if
                      you purchase shares in a 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 Fund will notify you annually as to the tax status of
                      dividend and capital gains distributions paid by each
                      Portfolio.
 
   
EACH PORTFOLIO MAY
"PASS THROUGH"
FOREIGN TAXES         Each Portfolio may elect to "pass through" to its
                      shareholders the amount of foreign income taxes paid by a
                      Portfolio. The Portfolios will make such an election only
                      if it is deemed to be in the best interests of the
                      shareholders. If this election is made, shareholders of a
                      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 (but not both) on their federal income tax
                      return.

A CAPITAL GAIN OR LOSS
MAY BE REALIZED
UPON EXCHANGE OR
REDEMPTION            A sale of shares of a 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). You are responsible for
                      calculating any capital gains or losses realized upon
                      redemption or exchange of a Portfolio's shares.
 
                      Dividend distributions, capital gains distributions, and
                      capital gains or losses from redemptions and exchanges may
                      be subject to state and local taxes.
 
   
                      Each 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 by 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, shares of the Fund will be exempt from
                      Pennsylvania personal property taxes.
 
                      The tax discussion set forth above is included for general
                      information only. Prospective investors should consult
                      their own tax advisers concerning the tax consequences of
                      an investment in the Fund.

THE SHARE PRICE OF
EACH PORTFOLIO        The share price or "net asset value per share" of each
                      Portfolio is determined by dividing the total market value
                      of the Portfolio's investments and other assets, less any
                      liabilities, by the number of outstanding shares of the
                      Portfolio. Portfolio securities are valued at the last
                      quoted sales price on the day the valuation is made. Price
                      information on listed securities is taken from the
                      exchange where the security is primarily traded.
                      Securities regularly traded in the over-the-counter market
                      are valued at the latest quoted bid price. Other assets
                      and securities for which no quotations are readily
                      available are valued at fair value as determined in good
                      faith by the Directors. Securities may be valued on the
                      basis of prices provided by a pricing service when such
                      prices are believed to reflect the fair market value of
                      such securities. All assets and liabilities initially
                      expressed in foreign currencies will be translated into
                      U.S. dollars using the officially quoted daily exchange
                      rates determined by Morgan Stanley Capital International
                      in the calculation of their Europe, Australia and Far East
                      Index. This officially quoted daily exchange rate may be
                      determined by Morgan Stanley Capital International 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 by the Board of Directors.
    
 
   
                      Generally, trading in foreign securities is completed each
                      day prior to the close of regular trading on the New York
                      Stock Exchange (generally 4:00 p.m. Eastern time). The
                      values of foreign securities held by each Portfolio are
                      typically determined as of the close of trading of foreign
                      securities in their respective markets. If events which
                      materially affect the value of a Portfolio's investments
                      occur after the close of the
    
 
                                       16
<PAGE>   19
 
                      securities markets on which such securities are primarily

GENERAL
INFORMATION           The Fund is organized as a Maryland corporation. The
                      Articles of Incorporation permit the Directors to issue
                      1,500,000,000 shares of common stock with a $.001 par
                      value. The Board of Directors has the power to designate
                      one or more classes ("series") of shares of common stock
                      and to classify or reclassify any unissued shares with
                      respect to such series. Currently the Fund is offering
                      shares of three series.
    
 
                      The shares of each series are fully paid and
                      non-assessable; have no preference as to conversion,
                      exchange, dividends, retirement or other features; and
                      have no pre-emptive rights. Such shares have
                      non-cumulative voting rights, meaning that the holders of
                      more than 50% of the shares voting for the election of
                      Directors can elect 100% of the Directors if they so
                      choose. Annual meetings of shareholders will not be held
                      except as required by the Investment Company Act of 1940
                      and other applicable law. An annual meeting will be held
                      to vote on the removal of a Director or Directors of the
                      Fund if requested in writing by the holders of not less
                      than 10% of the outstanding shares of the Fund.
 
   
                      All securities and cash are held by Morgan Stanley Trust
                      Company. The Vanguard Group, Inc., Valley Forge, PA,
                      serves as the Fund's Transfer and Dividend Disbursing
                      Agent. Price Waterhouse LLP, serves as independent
                      accountant 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 for each Portfolio ($500
                      for Uniform Gifts/Transfers to Minors Act accounts). You
                      must open a new Individual Retirement Account by mail
                      (IRAs may not be opened by wire) using a Vanguard IRA
                      Adoption Agreement. Your purchase must be equal to or
                      greater than the $500 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 Fund, please call our Investor Information
                      Department (1-800-662-7447). NOTE: For other types of
                      account registrations (e.g., corporations, associations,
                      other organizations, trusts or powers of attorney), please
                      call us to determine which additional forms you may need.
 
                      Because of the risks associated with common stock
                      investments, the Fund is intended to be a long-term
                      investment vehicle and is not designed to provide
                      investors with a means of speculating on short-term market
                      movements. Consequently, the Fund reserves the right to
                      reject any specific purchase (and exchange purchase)
                      request. The Fund also reserves the right to suspend the
                      offering of shares for a period of time.
 
                      The shares of both Portfolios are purchased at the
                      next-determined net asset value after your investment has
                      been received. The Fund is offered on a no-load basis
                      (i.e., there are no sales commissions or 12b-1 fees).
 
   
IMPORTANT NOTE
ON EXPENSES           Both Portfolios assess a transaction fee equal to 1% of
                      the dollar amount invested, as well as a $10 annual
                      account maintenance fee. The $10 annual account
                      maintenance fee will be waived for shareholders with an
                      account balance of $10,000 or more. See "Portfolio
                      Expenses."
    
 
ADDITIONAL
INVESTMENTS           Subsequent investments to regular accounts may be made by
                      mail ($100 minimum), wire ($1,000 minimum), written
                      exchange from another Vanguard Fund account ($100
                      minimum), or Vanguard Fund Express. Subsequent investments
                      to Individual Retirement Accounts may be made by mail
                      ($100 minimum) or exchange from another Vanguard Fund

                      wire or Vanguard Fund Express. Please call us for more

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

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 OPTIONS LATER, YOU MAY NEED TO PROVIDE VANGUARD WITH

                      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 adviser may charge a service fee.
 
   
CANCELLING TRADES     The Portfolios will not cancel any trade (e.g., purchase,
                      exchange or redemption) believed to be authentic, received
                      in writing or by telephone, once the trade request has
                      been received.

WHEN YOUR
ACCOUNT WILL
BE CREDITED           Your trade date is the date on which your account is
                      credited. If your purchase is made by check, Federal Funds
                      wire or exchange, and is received by the close of the New
                      York Stock Exchange (generally 4:00 p.m. Eastern time),
                      your trade date is the day of receipt. If your purchase is
                      received after the close of the Exchange, your trade date
                      is the next business day. There is a transaction fee equal
                      to 1% of the dollar amount invested. See "Portfolio
                      Expenses." Vanguard will not accept third-party checks to
                      open an account. Please be sure your purchase check is
                      made payable to the Vanguard Group.
    
 
                      In order to prevent lengthy processing delays caused by
                      the clearing of foreign checks, Vanguard will only accept
                      a foreign check which has been drawn in U.S. dollars and
                      has been issued by a foreign bank with a U.S.
                      correspondent bank. The name of the U.S. correspondent
                      bank must be printed on the face of the foreign check.

IMPORTANT
REDEMPTION
INFORMATION           Shares purchased by check or Fund Express may be redeemed
                      at any time. However, your redemption proceeds will not be
                      paid until payment for the purchase is collected, which
                      may take up to ten calendar days.
    
                      ----------------------------------------------------------
 
DELIVERY OF
REDEMPTION
PROCEEDS              Redemption requests received by telephone prior to the
                      close of the New York Stock Exchange (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

<PAGE>   25
 
                      Fund reserves the right to revise or terminate the
                      telephone redemption privilege at any time.
 
                      Each 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 a Portfolio's
                      remaining shareholders to make payment in cash, a
                      Portfolio may pay redemption proceeds in whole or in part
                      by a distribution in kind of readily marketable
                      securities.
                      ----------------------------------------------------------
 
VANGUARD'S AVERAGE
COST STATEMENT        If you make a redemption from a qualifying account,
                      Vanguard will send you an Average Cost Statement which
                      provides you with the tax basis of the shares you
                      redeemed. Please see "Other Vanguard Services" for
                      additional information.
                      ----------------------------------------------------------
 
   
MINIMUM ACCOUNT
BALANCE REQUIREMENT   Due to the relatively high cost of maintaining smaller
                      accounts, each Portfolio reserves the right to redeem
                      shares in any account that is below the minimum initial
                      investment amount of $3,000. If at any time your total
                      investment does not have a value of at least $3,000, you
                      may be notified that your account is below the Fund's
                      minimum account balance requirement. You would then be
                      allowed 60 days to make an additional investment before
                      the account is liquidated. Proceeds would be promptly paid
                      to the registered shareholder. (This minimum does not
                      apply to Individual Retirement Accounts, other retirement
                      accounts, or Uniform Gifts/Transfers to Minors Act
                      accounts.)
    
 
   
                      The Fund's minimum account balance requirement will not
                      apply if your account falls below $3,000 solely as a
                      result of declining markets (i.e., a decline in a
                      Portfolio's net asset value).

EXCHANGING YOUR
SHARES                Should your investment goals change, you may exchange your
                      shares of a Portfolio for those of other available
                      Vanguard Funds. Exchanges to or from a Portfolio may be
                      made only by mail. TELEPHONE EXCHANGES BETWEEN
                      NON-RETIREMENT ACCOUNTS ARE NOT ACCEPTED FOR THE FUND.
                      ----------------------------------------------------------
 
   
EXCHANGING BY MAIL    Please be sure to include on your exchange request the
                      name and account number of your current Portfolio, the
                      name of the Fund you wish to exchange into, the amount you
                      wish to exchange, and the signatures of all registered
                      account holders. Send your request to VANGUARD FINANCIAL
                      CENTER, VANGUARD INTERNATIONAL EQUITY INDEX FUND, P.O. BOX
                      1120, VALLEY FORGE, PA 19482. (For express or registered

IMPORTANT EXCHANGE
INFORMATION           Before you make an exchange, you should consider the
                      following:
 
                      - Please read the Fund's prospectus before making an
                        exchange. For an additional copy and for answers to any
                        questions you may have, call our Investor Information
                        Department (1-800-662-7447).
 
                                       23
<PAGE>   26
 
                      - 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 all 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 Fund 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 Fund are registered for sale. The
                      Fund's shares are currently registered for sale in all 50
                      states and the Fund intends to maintain such registration.
    
- --------------------------------------------------------------------------------
 
EXCHANGE
PRIVILEGE
LIMITATIONS           The Fund's exchange privilege is not intended to afford
                      shareholders a way to speculate on short-term movements in
                      the market. Accordingly, in order to prevent excessive use
                      of the exchange privilege that may potentially disrupt the
                      management of the Fund and increase transaction costs, the
                      Fund has established a policy of limiting excessive
                      exchange activity.
 
                      Exchange activity generally will not be deemed excessive
                      if limited to TWO SUBSTANTIVE EXCHANGE REDEMPTIONS (AT
                      LEAST 30 DAYS APART) from a Portfolio during any twelve
                      month period. Notwithstanding these limitations, the Fund
                      reserves the right to reject any purchase request
                      (including exchange purchases from other Vanguard
                      portfolios) that is reasonably deemed to be disruptive to
                      efficient portfolio management.

IMPORTANT
INFORMATION
ABOUT TELEPHONE
TRANSACTIONS          The ability to initiate redemptions (except wire
                      redemptions) 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.

<PAGE>   27
 
                      2. PAYMENT POLICY.  The proceeds of any telephone
                         redemption 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 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.

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.

                      average cost of shares redeemed from your account, using

INVESTMENT
OBJECTIVE
AND POLICIES          Vanguard International Equity Index Fund, Inc. (the
                      "Fund") is an open-end diversified investment company
                      designed as an "index" fund. The Fund consists of three
                      portfolios, Emerging Markets, European, and Pacific, each
                      of which invests in common stocks in order to match the
                      performance of a distinct international market index. This
                      prospectus relates only to the Emerging Markets Portfolio
                      (the "Portfolio"). The Portfolio seeks to provide
                      investment results, using statistical procedures, that
                      parallel the Morgan Stanley Capital
                      International -- Select Emerging Markets Free Index, a
                      broadly diversified index consisting of common stocks of
                      companies in twelve countries in Southeast Asia, Latin
                      America and Europe. The Portfolio intends to invest 95% of
                      its assets in securities which are representative of
                      securities in the Index and 5% in cash reserves. There is
                      no assurance that the Portfolio will achieve its stated
                      objective. Shares of the Fund are neither insured nor
                      guaranteed by any agency of the U.S. Government, including
                      the FDIC.

                      complete and return the Account Registration Form. If you
                      need assistance in completing this Form, please call our
                      Investor Information Department. To open an Individual
                      Retirement Account (IRA), please use a Vanguard IRA
                      Adoption Agreement. To obtain a copy of this form, call
                      1-800-662-7447, Monday through Friday, from 8:00 a.m. to
                      9:00 p.m. and Saturday, from 9:00 a.m. to 4:00 p.m.
                      (Eastern time). The minimum initial investment is $3,000
                      or $500 for Uniform Gifts/Transfers to Minors Act
                      accounts. The Portfolio is offered on a no-load basis
                      (i.e., there are no sales commissions or 12b-1 fees).
                      However, the Portfolio incurs expenses for investment
                      advisory, management, administrative and distribution
                      services. Shareholders of the Portfolio will be charged a
                      2% portfolio transaction fee on the amount of shares
                      purchased and a 1% portfolio transaction fee on
                      redemptions. These fees are paid to the Portfolio to
                      offset transaction costs of buying and selling securities.
                      There is also a $10 annual account maintenance fee. See
                      "Portfolio Expenses."

                      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 PORTFOLIO CHARGES
A 2% PURCHASE
TRANSACTION FEE       The Emerging Markets Portfolio assesses a portfolio
                      transaction fee on purchases of Portfolio shares equal to
                      2% of the dollar amount invested. The Portfolio
                      transaction fee is paid to the Portfolio, not to Vanguard.
                      It is not a sales charge. The fee applies to an initial
                      investment in the Portfolio and all subsequent purchases
                      (including purchases made by exchange from another
                      Vanguard Fund or from the other Portfolios of Vanguard
                      International Equity Index Fund), but not to reinvested
                      dividend or capital gain distributions. The Portfolio
                      purchase transaction fee is deducted automatically from
                      the amount invested; it cannot be paid separately.
 
THE PORTFOLIO CHARGES
A 1% REDEMPTION
TRANSACTION FEE       The Portfolio also assesses a 1% redemption transaction
                      fee. This 1% charge applies to redemptions or exchanges
                      from the Portfolio. The 1% fee is deducted from redemption
                      or exchange proceeds and is paid directly to the
                      Portfolio, not to Vanguard. It is not a contingent
                      deferred sales charge.
 
                      The purpose of the transaction fees is to allocate
                      transaction costs associated with purchases and
                      redemptions to the investors making those purchases and
                      redemptions, thus insulating existing shareholders from
                      transaction costs. Such costs include: (1) brokerage
                      costs; (2) market impact costs -- i.e., the increase or
                      decrease in market prices which may result when the
                      Portfolio purchases or sells thinly
 
                                        2
<PAGE>   33
 
                      traded stocks; and (3) the effect of the "bid-ask" spread
                      which may be wide on many international stocks.
 
                      The fees represent Vanguard's estimate of the brokerage
                      and other transaction costs incurred by the Portfolio in
                      purchasing and selling stocks in emerging markets. Without
                      the fees, the Portfolio would not be reimbursed for these
                      costs, which it incurs directly, resulting in reduced
                      investment performance for all shareholders of the
                      Portfolio. With the fees, the transaction costs of
                      purchasing and selling international stocks are borne not
                      by all existing shareholders, but by those investors
                      making the purchases and redemptions. Because the
                      purchasers and sellers, not the Portfolio, bear these
                      costs, the Portfolio is expected to track its benchmark
                      index more closely.
 
                      Transaction costs incurred when purchasing or selling
                      stocks of companies in emerging market countries are
                      extremely high. There are three components of transaction
                      costs -- brokerage fees, the difference between the
                      bid/asked spread and market impact. Each one of these
                      factors is significantly more expensive in emerging market
                      countries than in the United States, because of less
                      competition among brokers, lower utilization of technology
                      on the part of the exchanges and brokers, the lack of
                      derivative instruments and generally less liquid markets.
                      Consequently, brokerage commissions are high, bid/asked
                      spreads are wide and market impact is significant. In
                      addition to these customary costs, many of the countries
                      have exchange fees or stamp taxes.
 
   
THE PORTFOLIO WILL
CHARGE A $10 ACCOUNT
MAINTENANCE FEE       The Portfolio assesses an annual account maintenance fee
                      of $10 for each shareholder account. The purpose of the
                      $10 fee is to allocate part of the costs of maintaining
                      shareholder accounts equally to all accounts. This fee,
                      which is paid directly by shareholders, is deducted
                      annually from the Fund's dividend. See "Dividends, Capital
                      Gains and Taxes" for more information on this fee. The $10
                      fee amounts to 1.00% on a $1,000 investment in the
                      Portfolio, and 0.33% on a $3,000 investment. This fee will
                      be waived for shareholders with an account balance of
                      $10,000 or more.
    
 
                      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. The expenses include a 2%
                      portfolio purchase transaction fee and a 1% redemption
                      transaction fee.

                      Included in these estimates are account maintenance fees
                      of $10, $30, $50 and $100, respectively, for the periods
                      shown. The $10 annual account maintenance fee is a flat
                      charge which does not vary by the size of your investment.
                      Accordingly, for investments larger than $1,000, your
                      total expenses will be substantially lower in percentage
                      terms than this illustration implies.

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 the net
                      investment income per share earned during a 30-day period
                      by the net asset value per share on the last day of the
                      period. Net investment income includes interest and
                      dividend income earned on the Portfolio's securities; it
                      is net of all expenses and all recurring and nonrecurring
                      charges that have been applied to all shareholder
                      accounts. The yield calculation assumes that the net
                      investment income earned over 30 days is compounded
                      monthly for six months and then annualized. Methods used
                      to calculate advertised yields are standardized for all
                      stock and bond mutual funds. However, these methods differ
                      from the accounting methods used by the 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
OBJECTIVE             The Emerging Markets Portfolio seeks, with respect to 95%
                      of assets, to provide investment results that parallel the
                      Morgan Stanley Capital International ("MSCI")-Select
                      Emerging Markets Free Index ("Index"). The MSCI-Select
                      Emerging Markets Free Index is a diversified index
                      consisting of common stocks located in 12 countries. This
                      Index provides broader diversification and more liquidity
                      than other "published" emerging markets indexes and also
                      takes into consideration the trading capabilities of
                      foreigners in emerging stock market countries.
    
 
                      The Portfolio is neither sponsored by nor affiliated with
                      Morgan Stanley Capital International.

INVESTMENT
POLICIES
THE PORTFOLIO USES A
"PASSIVE" APPROACH TO
INVEST IN INTERNATIONAL
STOCKS                The Emerging Markets Portfolio is not managed according to
                      traditional methods of "active" investment management,
                      which involve the buying and selling of securities based
                      upon economic, financial and market analysis and
                      investment judgment. Instead, the Portfolio, utilizing a
                      "passive" or indexing investment approach, attempts to
                      approximate the investment performance of its target index
                      through statistical procedures.
 
   
                      The Portfolio invests in a statistically selected sample
                      of approximately 300 stocks included in the MSCI-Select
                      Emerging Markets Free Index, an index of equity securities
                      of companies located in the countries of 12 emerging
                      markets. Three countries, Malaysia, Brazil and Hong Kong
                      represent a majority of the MSCI-Select Emerging Markets
                      Free Index, with 19%, 18% and 13% of the market
                      capitalization

                      The Index includes only shares that U.S. investors are
                      "free" or allowed by law, to purchase and sell and that
                      have sufficient trading liquidity.
 
                      The Portfolio is expected to invest in approximately 300
                      stocks. Stocks are selected for inclusion in the Portfolio
                      in order to form a statistically representative sample
                      corresponding to the MSCI-Select Emerging Markets Free
                      Index. The Portfolio is constructed to have aggregate
                      investment characteristics (based on country, market
                      capitalization and industry weightings), fundamental
                      characteristics (such as return variability, earnings
                      valuation and yield) and liquidity measures, similar to
                      those of its Index.
 
                      The Portfolio's policy is to remain 95% invested in common
                      stocks. The remaining 5% of the Portfolio will be invested
                      in cash reserves in order to maintain a higher degree of
                      portfolio liquidity to meet daily redemption requests.
 
   
                      Under normal circumstances at least 80% of the assets of
                      the Portfolio will be invested in stocks that are
                      represented in the Index and futures contracts and options
                      thereon. The Portfolio may also invest up to 50% of its
                      assets in stock futures contracts, options, warrants,
                      convertible securities or swap agreements in order to
                      invest uncommitted cash balances, maintain liquidity to
                      meet shareholder redemptions, or minimize trading costs.
                      Any investment in futures contracts, options, warrants,
                      convertible securities or swap agreements over 20% of the
                      Portfolio's assets would be made in emergency situations,
                      for short-term purposes.
    
 
                      The Portfolio will not invest in cash reserves, futures
                      contracts, options, warrants or swap agreements as part of
                      a temporary defensive strategy to protect against
                      potential stock market declines. The Portfolio intends to
                      remain 95% invested, to the extent practicable, in a pool
                      of securities which will approximate the investment
                      characteristics of the MSCI-Select Emerging Markets Free
                      Index. The Portfolio may also enter into forward foreign
                      currency exchange contracts in order to maintain the same
                      currency exposure as the Index, but not as part of a
                      defensive strategy to protect against fluctuations in
                      exchange rates.

                      The investment objective and policies of the Portfolio are
                      not fundamental and so may be changed by the Board of
                      Directors without shareholder approval. However,
                      shareholders would be notified prior to a material change

INVESTMENT
RISKS
INTERNATIONAL STOCKS
MAY EXHIBIT GREATER
VOLATILITY THAN
U.S. STOCKS           As a mutual fund investing in common stocks, the Portfolio
                      is subject to market risk -- i.e., the possibility that
                      stock prices will decline over short or even extended
                      periods. Both U.S. and foreign stock markets tend to be
                      cyclical, with periods when stock prices generally rise
                      and periods when stock prices generally decline.
                      Investments in foreign stock markets can be volatile, if
                      not more volatile, than investments in U.S. markets.
 
                      In particular, emerging markets are associated with
                      substantial investment risks. These risks include market
                      volatility, investment illiquidity, currency risk,
                      political instability and unexpected changes in economic
                      policy including capital controls, expropriation, taxes
                      and hyper-inflation.
 
   
EMERGING MARKETS
MAY EXHIBIT GREATER
VOLATILITY THAN
DEVELOPED MARKETS     Investors should be aware that emerging markets can be
                      substantially more volatile than both U.S. and more
                      developed foreign markets. For example, from 1989-1994,
                      the average positive monthly return for the Wilshire 5000
                      Index, a broad measure of the US equity market was +2.9%.
                      The average negative monthly return for the Wilshire 5000
                      Index was -2.7%. In contrast, from 1989-1994, the average
                      positive monthly return of the Morgan Stanley Capital
                      International Emerging Markets Free Index, a widely quoted
                      emerging market benchmark, was +5.3%; while the average
                      negative monthly return was -5.3%.
    
 
INVESTMENT ILLIQUIDITY
RISK                  Volatility in emerging markets may be exacerbated by
                      illiquidity. Average daily trading volume in all of the
                      emerging markets combined is a small fraction of the
                      average daily volume of the US market. Small trading
                      volumes may result in investors being forced to purchase
                      securities at substantially higher prices than the current
                      market, or sell securities at much lower prices than the
                      current market.
 
CURRENCY RISK         Currency risk may have substantial influence on emerging
                      market returns as well. Currency risk refers to changes in
                      foreign exchange rates that will affect, favorably or
                      unfavorably, the value of foreign securities held by the
                      Portfolio. Currency risk in emerging markets may be
                      exacerbated by unexpected exchange rate devaluations.
 
OTHER SPECIAL
CONSIDERATIONS        In addition, returns could be dramatically diminished as a
                      result of unexpected political developments and changes in
                      economic policy. Coups, expropriations, unstable economic
                      policies and drastic changes in taxation policies have
                      been witnessed in some of these developing countries in
                      recent times.
 
                      Other considerations of international investing include:
                      differences in accounting, auditing and financial
                      reporting standards; generally higher transaction costs on
                      foreign portfolio transactions; foreign withholding taxes
                      payable on the Portfolio's foreign securities, which may
                      reduce dividend income payable to shareholders; adverse
                      changes in investment or exchange control regulations;
                      difficulty in
 
                                        7

                      obtaining judgments from foreign courts; and potential
                      restrictions on the flow of international capital.

WHO SHOULD INVEST
LONG-TERM INVESTORS
SEEKING TO INVEST
IN COMMON STOCKS OF
EMERGING MARKETS      The Emerging Markets Portfolio is designed for investors
                      who seek a low-cost "passive" approach for investing in a
                      broadly diversified portfolio of common stocks of
                      companies located in emerging international markets.
                      Unlike other equity mutual funds, which generally seek to
                      "beat" market averages with unpredictable results, the
                      Portfolio seeks to parallel the performance of its Index
                      and thus is expected to provide a predictable return
                      relative to its benchmark. In particular, the Portfolio is
                      designed for investors seeking to approximate the total
                      investment results (before fund expenses and withholding
                      taxes) of the MSCI-Select Emerging Markets Free Index, a
                      diversified index of common stocks of emerging market
                      countries.
 
                      The share price of the Portfolio is expected to be
                      volatile, and investors should be able to tolerate sudden,
                      sometimes substantial fluctuations in the value of their
                      investment. No assurance can be given that the Portfolio
                      will achieve its stated objective or that shareholders
                      will be protected from the risks inherent in equity and
                      international investing. Investors may wish to minimize
                      the timing risk of investing in a Portfolio by purchasing
                      shares on a periodic basis (dollar-cost averaging) rather
                      than investing in one lump sum.
 
   
                      Because of the risks associated with international common
                      stock investments and emerging markets in particular, 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. 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 an exchange purchase from another
                      Vanguard portfolio) 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. Investors should not consider the
                      Portfolio a complete investment program, but should
                      maintain holdings of securities with different risk
                      characteristics -- including U.S. common stocks, bonds and
                      money market instruments.

IMPLEMENTATION
OF POLICIES
THE PORTFOLIO INVESTS
IN INTERNATIONAL
COMMON STOCKS USING
A SAMPLING TECHNIQUE  The Emerging Markets Portfolio utilizes a number of
                      investment practices in an effort to parallel the
                      investment performance of its target Index.
 
   
                      The MSCI-Select Emerging Markets Free Index consists of
                      approximately 490 equity securities from emerging market
                      countries in Europe, Latin America and Southeast Asia. The
                      stocks included in the Index are chosen on a statistical
                      basis. The companies based in Hong Kong and Singapore are
                      included in the Index to provide participation in more
                      liquid emerging markets; their combined weight is limited
                      to
    
 
                                        8
<PAGE>   39
 
                      20% of the Index. Each stock within Hong Kong and
                      Singapore will be weighted according to its market value
                      as a percentage of the total market value of all of the
                      Hong Kong and Singapore stocks included in the index. (A
                      stock's market value equals the number of shares
                      outstanding times the most recent price of the security).
                      The remaining portion of the Index will be comprised of
                      common stocks from 10 other emerging market
                      countries -- Indonesia, Malaysia, the Philippines,
                      Thailand, Argentina, Brazil, Mexico, Greece, Portugal and
                      Turkey. Each stock in these countries will be weighted
                      according to its market value as a percentage of the total
                      market value of the companies in the 10 countries
                      multiplied by the percentage of the index that these
                      countries represent. From time to time, additional
                      emerging markets will be analyzed for inclusion in the
                      Index, based on liquidity and tradeability. The inclusion
                      of a country or stock in the Index in no way implies that
                      the country or stock is an attractive investment.
 
                      The Portfolio will be unable to hold all of the issues
                      that comprise its Index, because of the transaction costs
                      involved and the illiquidity of many of the securities.
                      Instead, the Portfolio will attempt to hold a
                      representative sample of approximately 300 or more of the
                      securities in its Index by selecting stocks utilizing a
                      statistical technique known as "portfolio optimization."
                      Under this technique, each stock is considered for
                      inclusion in the Portfolio based on its contribution to
                      certain country, capitalization, industry, liquidity and
                      fundamental investment characteristics. The Portfolio is
                      constructed so that, in the aggregate, the Portfolio's
                      country, capitalization, industry, and fundamental
                      investment characteristics resemble those of the Index.
                      Over time, the portfolio composition is altered (or
                      "rebalanced") to reflect changes in the characteristics of
                      the Index.
 
                      Due to the use of this sampling or "portfolio
                      optimization" technique, the Portfolio is not expected to
                      track its benchmark with the same degree of accuracy as
                      large capitalization domestic index funds. Over time, the
                      correlation between the performance of the Portfolio and
                      the Index is expected to be greater than 0.95. A
                      correlation of 1.00 would indicate perfect correlation,
                      which would be achieved when the net asset value of the
                      Portfolio, including the value of its dividend and capital
                      gains distributions, increases or decreases in exact
                      proportion to changes in the Index. A correlation of 0.95
                      or higher is expected to be achieved when the Portfolio
                      exceeds $100 million in assets.
 
   
THE PORTFOLIO MAY
INVEST IN SHORT-TERM
FIXED INCOME
SECURITIES            The Portfolio's policy is to remain 95% invested in common
                      stocks and it is expected to invest 5% of its assets in
                      certain short-term fixed income securities. In addition,
                      the Portfolio may invest temporarily in short-term fixed
                      income securities in excess of 5% in order to invest
                      uncommitted cash balances or to maintain liquidity to meet

THE PORTFOLIO MAY USE
FUTURES CONTRACTS,
OPTIONS, WARRANTS,
CONVERTIBLE SECURITIES
AND SWAP AGREEMENTS   The Portfolio may utilize stock futures contracts,
                      options, warrants, convertible securities and swap
                      agreements to a limited extent. Specifically, the
                      Portfolio may enter into futures contracts and options
                      provided that not more than 5% of its assets are required
                      as a margin deposit for futures contracts or options.
                      Additionally, the Portfolio's investment in warrants will
                      not exceed more than 5% of its assets. Futures contracts,
                      options, warrants, convertible securities and swap
                      agreements may be used for several reasons: to simulate
                      full investment in the underlying index while retaining a
                      cash balance for fund management purposes, to facilitate
                      trading, to reduce transaction costs or to seek higher
                      investment returns when a futures contract, option,
                      warrant, convertible security or swap agreement is priced
                      more attractively than the underlying equity security or
                      index. While each of these securities can be used as
                      leveraged investments, the Portfolio may not use them to
                      leverage its net assets.
 
FUTURES CONTRACTS,
OPTIONS, WARRANTS,
CONVERTIBLE SECURITIES
AND SWAP AGREEMENTS
POSE CERTAIN RISKS    The risk of loss associated with 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 an immediate and substantial loss or gain.
                      However, the Portfolio will not use futures contracts,
                      options, warrants, convertible securities or swap
                      agreements for speculative purposes or to leverage its net
                      assets. Accordingly, the primary risks associated with the
                      use of futures contracts, options, warrants, convertible
                      securities or swap agreements by the Portfolio are: (i)
                      imperfect correlation between the change in market value
                      of the stocks held by the Portfolio and the prices of
                      futures contracts, options, warrants, convertible
                      securities or swap agreements; (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; and (iii) the risk of the counterparty
                      or guaranteeing agent defaulting. 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 an
                      exchange with an active and liquid secondary market.
                      However, options, warrants, convertible securities or swap
                      agreements purchased or sold over-the-counter may be less
                      liquid than exchange traded securities. Illiquid
                      securities, in general, including swap agreements, may not
                      represent more than 15% of the net assets of the
                      Portfolio.
 
                      Since there are currently no futures traded on the
                      MSCI-Select Emerging Markets Free Index, it will be
                      necessary for the Portfolio to utilize a composite of
                      other futures contracts to simulate the performance of the
                      Index. This process may magnify the "tracking error" of
                      the Portfolio's performance compared to that of the Index,
                      due to lower correlation of the selected futures with the
                      Index. The investment adviser would attempt to reduce this
                      tracking error by investing in futures contracts whose
                      behavior is expected to resemble that of the underlying
                      securities, although there can be no assurance that these
                      selected futures will perfectly correlate with the
                      performance of the Index.

                      Swap agreements are contracts between parties in which one
                      party agrees to make payments to the other party based on
                      the change in market value of a specified index or asset.
                      In return, the other party agrees to make payments to the
                      first party based on the return of a different specified
                      index or asset. Although swap agreements entail the risk
                      that a party will default on its payment obligations
                      thereunder, the Portfolio would minimize this risk by
                      entering into agreements that mark to market no less
                      frequently than quarterly. Swap agreements also bear the
                      risk that the Portfolio will not be able to meet its
                      obligation to the counterparty. This risk would be
                      mitigated by investing the Portfolio in a specific asset
                      for which it is obligated to pay a return.
 
THE PORTFOLIO MAY
ENTER INTO FORWARD
CURRENCY CONTRACTS    The Portfolio may enter into foreign currency forward and
                      foreign currency futures contracts in order to maintain
                      the same currency exposure as the Index. The Portfolio may
                      not enter into such contracts for speculative purposes, or
                      as a way of protecting against anticipated adverse changes
                      in exchange rates between foreign currencies and the U.S.
                      dollar. A foreign currency forward 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.
 
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 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. The
                      collateral will equal at least 100% of the current market
                      value of the loaned securities.
 
PORTFOLIO TURNOVER IS
EXPECTED TO BE LOW    Although the Portfolio generally seeks to invest for the
                      long term, the Portfolio retains the right to sell
                      securities irrespective of how long they have been held.
                      However, because of the "passive" investment management
                      approach of the Portfolio, the portfolio turnover rate for
                      the Portfolio is expected to be under 50%, a generally
                      lower turnover rate than for most other investment
                      companies. A portfolio turnover rate of 50% would occur if
                      one half of the Portfolio's securities were sold within
                      one year. Ordinarily, securities will be sold from the
                      Portfolio only to reflect certain administrative changes
                      in an index (including mergers or changes in the
                      composition of an index) or to accommodate cash flows out
                      of the Portfolio while maintaining the similarity of the
                      Portfolio to its benchmark index.
 
   
THE PORTFOLIO MAY
BORROW MONEY          The Portfolio may borrow money from a bank up to a limit
                      of 15% of the market value of its assets, but only for
                      temporary or emergency purposes. The Portfolio may borrow
                      money only to meet redemption requests prior to the
                      settlement of securities already sold or in the process of
                      being sold by the Portfolio. To the extent that the
                      Portfolio borrows money prior to selling securities, the
                      Portfolio may be leveraged; at such times, the Portfolio
                      may appreciate or depreciate in value more rapidly than
                      its benchmark index. The Portfolio will repay any money
                      borrowed in excess of 5% of the market value of its total
                      assets prior to purchasing additional portfolio
                      securities.

INVESTMENT
LIMITATIONS
THE PORTFOLIO HAS
ADOPTED CERTAIN
FUNDAMENTAL
LIMITATIONS           The Portfolio has adopted certain limitations on its
                      investment practices. Some of these limitations are that
                      the Portfolio will not:
 
                      (a) with respect to 75% of its assets, purchase securities
                          of any issuer (except obligations of the U.S.
                          Government and its instrumentalities) if, as a result,
                          more than 5% of the value of the Portfolio's assets
                          would be invested in the securities of such issuer;
                      (b) purchase more than 10% of the voting securities of any
                          issuer;
                      (c) invest more than 25% of its assets in any one
                          industry; and
                      (d) borrow money except from banks for temporary or
                          emergency purposes and in no event in excess of 15% of
                          the market value of its total assets.
 
                      These investment limitations are considered at the time
                      investment securities are purchased. The limitations
                      described here and in the Statement of Additional
                      Information may be changed only with the approval of a
                      majority of the Fund's shareholders.

MANAGEMENT OF
THE FUND
VANGUARD ADMINISTERS
AND DISTRIBUTES
THE PORTFOLIO         The Portfolio is one of three portfolios of Vanguard
                      International Equity Index Fund ("the Fund") and is a
                      member of The Vanguard Group of Investment Companies, a
                      family of more than 30 investment companies with more than
                      80 distinct investment portfolios and total assets in
                      excess of $130 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 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 Portfolio manage its day-to-day
                      operations and are responsible to the Portfolio's Board of
                      Directors. The Directors set broad policies for the
                      Portfolio and choose its Officers. A list of the Directors
                      and Officers of the Portfolio 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 to provide the requisite services
                      to the funds and also furnishes the funds with necessary
                      office space, furnishings and equipment. Each fund pays
                      its share of Vanguard's net expenses, which are allocated
                      among the funds under methods approved by the Board of
                      Directors (Trustees) of each fund. In addition, each fund
                      bears its own direct expenses, such as legal, auditing and
                      custodian fees.
 
                      Vanguard provides distribution and marketing services to
                      the funds. The funds are available on a no-load basis
                      (i.e., there are no sales commissions or 12b-1 fees).
                      However, each fund bears its own share of the Group's
                      distribution costs.

ADVISER
VANGUARD MANAGES
THE PORTFOLIO ON AN
AT-COST BASIS         The Portfolio receives all investment advisory services on
                      an at-cost basis from Vanguard's Core Management Group,
                      which also provides investment advisory services to the
                      European and Pacific Portfolios of the Fund, Vanguard
                      Index Trust, Vanguard Balanced Index Fund, Vanguard
                      Institutional Index Fund, a portion of the assets of
                      Vanguard/Windsor II, Vanguard Variable Insurance Fund, a
                      portion of the assets of Vanguard/Morgan Growth Fund, the
                      Equity Index Portfolio of the Vanguard Variable Insurance
                      Fund, Vanguard Tax-Managed Fund and several indexed
                      separate accounts. Total indexed assets under management
                      as of December 31, 1994 were $18.0 billion. The Portfolio
                      is not actively managed, but is instead administered by
                      the Core Management Group using computerized, quantitative
                      techniques. The Group is supervised by the Officers of the
                      Portfolio.
    
 
                      In placing portfolio transactions, Vanguard's Core
                      Management Group uses its best judgment to choose the
                      broker most capable of providing the brokerage services
                      necessary to obtain the best available price and most
                      favorable execution at the lowest commission rate. The
                      full range and quality of brokerage services available are
                      considered in making these determinations. In those
                      instances where it is reasonably determined that more than
                      one broker can offer the services needed to obtain the
                      best available price and most favorable execution,
                      consideration may be given to those brokers which supply
                      statistical information and provide other services in
                      addition to execution services to the Portfolio.

DIVIDENDS,
CAPITAL GAINS
AND TAXES
DIVIDENDS AND ANY
CAPITAL GAINS WILL BE
PAID ANNUALLY         The Portfolio intends to distribute substantially all of
                      its ordinary income in the form of an annual dividend.
                      Capital gains distributions, if any, are also made
                      annually.
 
                      The Portfolio's dividend and capital gains distributions
                      may be reinvested in additional shares 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 WILL
CHARGE A $10 ACCOUNT
MAINTENANCE FEE       The Portfolio will automatically deduct a $10 account
                      maintenance fee from the dividend income of the Portfolio
                      account annually. If the dividend to be paid to an account
                      is less than the fee to be deducted, sufficient shares
                      will be redeemed from an account to make up the
                      difference. The Board of Directors reserves the right to
                      change the annual account maintenance fee to reflect the
                      actual cost of maintaining smaller shareholder accounts.
                      For federal tax purposes, the account maintenance fee does
                      not reduce dividend income and is treated as an investment
                      expense by each shareholder (deductible as a miscellaneous
                      itemized deduction in the case of individual investors).
                      This fee will be waived for shareholders with an account
                      balance of $10,000 or more.

                      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 not generally 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 as long-term capital gains,
                      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 its
                      shareholders the amount of foreign income taxes paid by
                      the Portfolio. The Portfolio will make such an election
                      only if it is deemed to be in the best interests of the
                      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 (but not both) on their federal income 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). You are responsible for
                      calculating any capital gains or losses realized upon
                      redemption or exchange of the Portfolio's shares.
 
                      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
 
                                       14
<PAGE>   45
 
   
                      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 by 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, shares of the Portfolio will be 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 share price or "net asset value per share" of the
                      Portfolio is determined by dividing the total market value
                      of the Portfolio's investments and other assets, less any
                      liabilities, by the number of outstanding shares of the
                      Portfolio. Portfolio securities are valued at the last
                      quoted sales price on the day the valuation is made. Price
                      information on listed securities is taken from the
                      exchange where the security is primarily traded.
                      Securities regularly traded in the over-the-counter market
                      are valued at the latest quoted bid price. Other assets
                      and securities for which no quotations are readily
                      available are valued at fair value as determined in good
                      faith by the Directors. Securities may be valued on the
                      basis of prices provided by a pricing service when such
                      prices are believed to reflect the fair market value of
                      such securities. All assets and liabilities initially
                      expressed in foreign currencies will be translated into
                      U.S. dollars using the officially quoted daily exchange
                      rates determined by Morgan Stanley Capital International
                      in the calculation of the MSCI-Select Emerging Markets
                      Free Index. This officially quoted daily exchange rate may
                      be determined by Morgan Stanley Capital International
                      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 by the Board of Directors.
    
 
   
                      Generally, trading in foreign securities is completed each
                      day prior to the close of regular trading on the New York
                      Stock Exchange (generally 4:00 p.m. Eastern time). The
                      values of foreign securities held by the Portfolio are
                      typically determined as of the close of trading of foreign
                      securities in their respective markets. If events which
                      materially affect the value of the 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" as described above.

GENERAL
INFORMATION           The Fund is organized as a Maryland corporation. The
                      Articles of Incorporation permit the Directors to issue
                      1,500,000,000 shares of common stock with a $.001 par
                      value. The Board of Directors has the power to designate
                      one or more classes ("series") of shares of common stock
                      and to classify or reclassify any unissued shares with
                      respect to such series. Currently the Fund is offering
                      shares of three series.
    
 
                                       15
<PAGE>   46
 
   
                      The shares of each series are fully paid and
                      non-assessable; have no preference as to conversion,
                      exchange, dividends, retirement or other features; and
                      have no pre-emptive rights. Such shares have
                      non-cumulative voting rights, meaning that the holders of
                      more than 50% of the shares voting for the election of
                      Directors can elect 100% of the Directors if they so
                      choose. Annual meetings of shareholders will not be held
                      except as required by the Investment Company Act of 1940
                      and other applicable law. An annual meeting will be held
                      to vote on the removal of a Director or Directors of the
                      Fund if requested in writing by the holders of not less
                      than 10% of the outstanding shares of the Fund.
    
 
   
                      All securities and cash are held by Morgan Stanley Trust
                      Company. The Vanguard Group, Inc., Valley Forge, PA,
                      serves as the Fund's Transfer and Dividend Disbursing
                      Agent. Price Waterhouse LLP serves as independent
                      accountant 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 the 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 for the Portfolio ($500 for
                      Uniform Gifts/Transfers to Minors Act accounts). You must
                      open a new Individual Retirement Account by mail (IRAs may
                      not be opened by wire) using a Vanguard IRA Adoption
                      Agreement. Your purchase must be equal to or greater than
                      the $500 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 in 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
                      (1-800-662-7447). NOTE: For other types of account
                      registrations (e.g., corporations, associations, other
                      organizations, trusts or powers of attorney), please call
                      us to determine which additional forms you may need.
    
 
                      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. 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.
 
   
IMPORTANT NOTE
ON EXPENSES           The Portfolio assesses a purchase transaction fee equal to
                      2% of the dollar amount invested, as well as a redemption
                      transaction fee equal to 1% of the amount redeemed and a
                      $10 annual account maintenance fee. The $10 annual account
                      maintenance fee will be waived for shareholders with an
                      account balance of $10,000 or more. See "Portfolio
                      Expenses" for more information.
    
 
                      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).
 
ADDITIONAL
INVESTMENTS           Subsequent investments to regular accounts may be made by
                      mail ($100 minimum), wire ($1,000 minimum), written
                      exchange from another Vanguard Fund account ($100
                      minimum), 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
DISTRIBUTION
OPTION
                      You must select one of three distribution options:
 
                      1. AUTOMATIC REINVESTMENT OPTION--Both dividends and
                         capital gains distributions will be reinvested in
                         additional shares. This option will be selected for you
                         automatically unless you specify one of the other
                         options.
 
                      2. CASH DIVIDEND OPTION--Your dividends will be paid in
                         cash and your capital gains will be reinvested in
                         additional shares.
 
                      3. ALL CASH OPTION--Both dividend and capital gains
                         distributions will be paid in cash.
 
                      You may change your option by calling our Client Services
                      Department (1-800-662-2739).
 
                      In addition, an option to invest your cash dividends
                      and/or capital gains distributions in another Vanguard
                      Fund account is available. Please call our Client Services
                      Department (1-800-662-2739) for information. You may also
                      elect Vanguard Dividend Express which allows you to
                      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 gain distributions normally
                      occur in December. For additional information on
                      distributions and taxes, see the section titled
                      "Dividends, Capital Gains, and Taxes."

WHEN YOUR
ACCOUNT WILL
BE CREDITED           Your trade date is the date on which your account is
                      credited. If your purchase is made by check, Federal Funds
                      wire or exchange, and is received by the close of the New
                      York Stock Exchange (generally 4:00 p.m. Eastern time),
                      your trade date is the day of receipt. If your purchase is
                      received after the close of the Exchange, your trade date
                      is the next business day. There is a purchase transaction
                      fee equal to 2% of the dollar amount invested. See
                      "Portfolio Expenses" for additional information. Vanguard
                      will not accept third-party checks to open an account.
                      Please be sure your purchase check is made payable to the
                      Vanguard Group.
    
 
                      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

                      request in writing or by telephone. Your redemption
                      proceeds are normally mailed within two business days
                      after the receipt of the request in Good Order. There is a
                      redemption transaction fee equal to 1% of the dollar
                      amount redeemed. See "Portfolio Expenses" for additional

IMPORTANT REDEMPTION
INFORMATION           Shares purchased by check or Fund Express may be redeemed
                      at any time. However, your redemption proceeds will not be
                      paid until payment for the purchase is collected, which
                      may take up to ten calendar days.
    
- --------------------------------------------------------------------------------
 
DELIVERY OF
REDEMPTION
PROCEEDS              Redemption requests received by telephone prior to the
                      close of the New York Stock Exchange (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
 
                                       21
<PAGE>   52
 
                      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 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.
- --------------------------------------------------------------------------------
 
   
MINIMUM ACCOUNT
BALANCE REQUIREMENT   Due to the relatively high cost of maintaining smaller
                      accounts, the Portfolio reserves the right to redeem
                      shares in any account that is below the minimum initial
                      investment amount of $3,000. If at any time your total
                      investment does not have a value of at least $3,000, you
                      will be notified that 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. (This minimum
                      does not apply to Individual Retirement Accounts, other
                      retirement accounts, or Uniform Gifts/Transfers to Minors
                      Act accounts).
    
 
   
                      The Fund's minimum account balance requirement will not
                      apply if your account falls below $3,000 solely as a
                      result of declining markets (i.e., a decline in a
                      Portfolio's net asset value).

                      shares of the Portfolio for those of other available
                      Vanguard Funds. Exchanges to or from the Portfolio may be

IMPORTANT EXCHANGE
INFORMATION           Before you make an exchange, you should consider the
                      following:
 
                      - Please read the Portfolio's prospectus before making an
                        exchange. For an additional 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 all 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 transaction 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) 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 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 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.

                                   HIGHLIGHTS
 
                   Vanguard offers four index funds consisting of a total of
                   fourteen separate portfolios. Unlike other mutual funds which
                   generally attempt to "beat" market averages with often
                   unpredictable results, Vanguard's index funds seek to "match"
                   the performance of their underlying indexes and thus are
                   expected to provide a highly predictable return relative to
                   their benchmarks. The Funds offer investors the advantages of
                   a "passive" approach to investing. These include low
                   investment costs, exceptional diversification among
                   securities, minimal portfolio turnover, and relative
                   predictability.
 
                   As with any mutual fund there is no assurance that the Funds
                   will meet their objectives.

                     performance of the Lehman Brothers Aggregate Bond Index.
                   - The SHORT-TERM BOND PORTFOLIO seeks to replicate the

                     Government/Corporate Index.
                   - The INTERMEDIATE-TERM BOND PORTFOLIO seeks to replicate the

                   Each Portfolio will invest at least 80% of its assets in
                   securities included in its respective index. The Lehman
                   Brothers Indexes encompass two major classes of investment
                   grade fixed income securities: U.S. Treasury and agency
                   securities and corporate bonds. Additionally, the Lehman
                   Brothers Aggregate Bond Index includes mortgage-backed
                   securities.                                           PAGE 11

VANGUARD BALANCED
INDEX FUND         The Fund invests in U.S. common stocks and bonds. It seeks to

                   assets, the Lehman Brothers Index. Under normal circumstances
                   the Fund will invest primarily in securities of its
                   underlying indexes.                                   PAGE 11

VANGUARD
INTERNATIONAL
EQUITY INDEX FUND  The Fund consists of three Portfolios each of which invests
                   in international common stocks.
 
                   - The EUROPEAN PORTFOLIO seeks to parallel the performance of
                     the Morgan Stanley Capital International -- Europe (Free)
                     Index.
                   - The PACIFIC PORTFOLIO seeks to parallel the performance of
                     the Morgan Stanley Capital International -- Pacific Index.
                   - The EMERGING MARKETS PORTFOLIO seeks to parallel the
                     performance of the Morgan Stanley Capital
                     International -- Select Emerging Markets Free Index.
 
                   The European Portfolio and the Pacific Portfolio invest
                   primarily in the common stocks included in their respective
                   indexes. The Emerging Markets Portfolio invests 95% of its
                   assets in securities which are representative of securities
                   in its index and 5% in cash reserves.                 PAGE 12

INVESTMENT
RISKS              The Portfolios of the Vanguard Bond Index Fund and the bond
                   portion of the Vanguard Balanced Fund are subject to risks
                   associated with fixed income investing including interest
                   rate, income, call and credit risks. Additionally, since the
                   Total Bond Market Portfolio of Vanguard Bond Index Fund
                   invests in mortgage-backed securities, the Portfolio is
                   subject to prepayment risk.
 
                   The equity portion of Vanguard Balanced Index Fund and the
                   Portfolios of Vanguard Index Trust and Vanguard International
                   Equity Index Fund are subject to stock market risk, which is
                   the possibility that common stock prices will decline over
                   short or extended periods. Both U.S. and foreign stock
                   markets tend to be cyclical, with periods when stock prices
                   generally rise and periods when stock prices generally
                   decline. Additionally, the Portfolios of Vanguard
                   International Equity Index Fund are subject to currency risk,
                   the risk that changes in foreign exchange rates will affect
                   the value of foreign securities held by the Portfolios.
 
                   Investors considering the Emerging Markets Portfolio should
                   be aware that emerging markets can be substantially more
                   volatile than both U.S. and more developed foreign markets.
                   Volatility in emerging markets can be exacerbated by
                   illiquidity in the market for emerging market stocks.
 
                   Because of the risks associated with common stocks and bonds,
                   the Funds are intended to be long-term investment vehicles
                   and are not designed to provide investors with a means of
                   speculating on short-term market movements. Investors should
                   not consider an investment in any one portfolio a complete
                   investment program, but should maintain holdings of
                   securities with different risk characteristics -- including
                   U.S. common stocks, bonds and money market instruments. For
                   further information concerning the risks associated with
                   investing in the Funds, see "Investment Risks".       PAGE 17

THE VANGUARD
GROUP              The Funds are members of The Vanguard Group of Investment
                   Companies, a group of more than 30 investment companies with
                   more than 80 distinct investment portfolios and total assets
                   in excess of $130 billion. The Vanguard Group, Inc.
                   ("Vanguard"), a subsidiary jointly owned by the Vanguard
                   Funds, provides all corporate management, administrative,
                   distribution and shareholder accounting services on an
                   at-cost basis to the Funds in the Group.              PAGE 30

INVESTMENT
ADVISERS           The Vanguard Bond Index Fund and the bond portion of Vanguard
                   Balanced Index Fund receive investment advisory services from
                   Vanguard's Fixed Income Group. Vanguard Index Trust, Vanguard
                   International Equity Index Fund and the equity portion of
                   Vanguard Balanced Index Fund receive investment advisory
                   services from Vanguard's Core Management Group. All
                   investment advisory services are provided to the Index Funds
                   on an at-cost basis. As a result, the Funds receive
                   investment advisory services at a substantially lower cost
                   than would be possible if the Funds paid an investment
                   advisory fee to an external investment adviser.       PAGE 31

SIX PORTFOLIOS ASSESS
TRANSACTION FEES   The Small Capitalization Stock Portfolio of Vanguard Index
                   Trust and the European and Pacific Portfolios of Vanguard
                   International Equity Index Fund assess a portfolio
                   transaction fee on purchases of Portfolio shares equal to 1%
                   of the dollar amount invested. The Total Stock Market
                   Portfolio of Vanguard Index Trust assesses a portfolio
                   transaction fee equal to 0.25% of the dollar amount invested.
                   The Extended Market Portfolio of Vanguard Index Trust
                   assesses a portfolio transaction fee equal to 0.5% of the
                   dollar amount invested. The Emerging Markets Portfolio of
                   Vanguard International Equity Index Fund assess a portfolio
                   transaction fee equal to 2% of the dollar amount invested.
                   The portfolio transaction fees are paid to the respective
                   Portfolio, not to Vanguard. They are not sales charges.
    
 
                   These fees apply to initial investments in the respective
                   Portfolios and all subsequent purchases (including purchases
                   made by exchange from another Vanguard Fund or from other
                   Portfolios within a Fund), but not to reinvested dividend or
                   capital gains distributions. Portfolio transaction fees are
                   deducted automatically from the amount invested; they cannot
                   be paid separately.
 
                   The purpose of these transaction fees is to allocate
                   transaction costs associated with new purchases to investors
                   making those purchases, thus insulating existing shareholders
                   from those transaction costs. These costs include: (1)
                   brokerage costs; (2) market impact costs -- i.e., the
                   increase in market prices which may result when the Portfolio
                   purchases thinly traded stocks; and, most importantly, (3)
                   the effect of the "bid-ask" spread in the over-the-counter
                   market. (Securities in the over-the-counter market are bought
                   at the "ask" or purchase price, but are valued in the
                   Portfolio at the mean of the "bid" or sale, and "ask"
                   prices.)
 
                   The fees represent Vanguard's estimate of the brokerage and
                   other transaction costs incurred by the Portfolios in
                   acquiring stocks in their respective markets. Without the
                   fees, the Portfolios, which incur these costs directly, would
                   experience reduced investment performance for all
                   shareholders in each Portfolio. With the fees, the
                   transaction costs of acquiring additional stocks are borne
                   not by all existing shareholders, but by those investors
                   making additional purchases. Because the purchaser, not the
                   Portfolios, bears these costs, the Portfolios are expected to
                   track their respective benchmark indexes more closely.
 
THE EMERGING MARKETS
PORTFOLIO CHARGES A
1% REDEMPTION
TRANSACTION FEE    The Emerging Markets Portfolio of Vanguard International
                   Equity Index Fund also assesses a 1% redemption transaction
                   fee. This 1% charge applies to redemptions or exchanges from
                   the Portfolio. The 1% fee is deducted from redemption or
                   exchange proceeds and is paid directly to the Portfolio, not
                   to Vanguard. It is not a contingent deferred sales charge.

EACH PORTFOLIO CHARGES
A $10 ACCOUNT
MAINTENANCE FEE    Each Portfolio assesses an annual account maintenance fee of
                   $10 to allocate part of the fixed costs of maintaining
                   shareholder accounts equally to all accounts. This fee is
                   deducted from each Portfolio's dividend at a rate of $2.50
                   per quarter for accounts in the 500, Total Stock Market,
                   Value and Growth Portfolios of Vanguard Index Trust, Vanguard
                   Bond Index Fund and Vanguard Balanced Index Fund and $10
                   annually for accounts in the Extended Market Portfolio of
                   Vanguard Index Trust and the European, Pacific and Emerging
                   Markets Portfolios of Vanguard International Equity Index
                   Fund. See "Dividends, Capital Gains and Taxes" for more
                   information on this fee. The $10 fee amounts to 1.00% on a
                   $1,000 investment in a Portfolio, and 0.33% on a $3,000
                   investment. This fee will be waived for shareholders with an
                   account balance of $10,000 or more.
    
 
                   The following example illustrates the expenses that you would
                   incur on a $1,000 investment over various time periods,
                   assuming (1) a 5% annual rate of return and (2) redemption at
                   the end of each period. The example includes the $10 account
                   maintenance fee for each Portfolio; the 1% portfolio
                   transaction fee for the Extended Market and Small
                   Capitalization Stock Portfolios of Vanguard Index Trust and
                   the European and Pacific Portfolios of Vanguard International
                   Equity Index Fund; the 0.25% transaction fee for the Total
                   Stock Market Portfolio of Vanguard Index Trust; and the 2%
                   purchase transaction fee and the 1% redemption transaction
                   fee for the Emerging Markets Portfolio of Vanguard
                   International Equity Index Fund.

                   Included in these estimates are account maintenance fees of
                   $10, $30, $50 and $100 for the respective periods shown. The
                   $10 account maintenance fee is a flat charge which does not
                   vary by the size of your investment. Accordingly, for
                   investments larger than $1,000, your total expenses will be
                   substantially lower in percentage terms than this
                   illustration implies.

YIELD AND TOTAL
RETURN             From time to time a Portfolio of the Vanguard Index Funds 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 a 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 a
                   Portfolio is calculated by dividing the net investment income
                   per share earned during a 30-day period by the net asset
                   value per share on the last day of the period. Net investment
                   income includes interest and dividend income earned on a
                   Portfolio's securities; it 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 a 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.

BOND INDEX FUND
EACH PORTFOLIO SEEKS
TO MATCH THE
INVESTMENT
PERFORMANCE OF ITS
RESPECTIVE INDEX   The Fund consists of four Portfolios, each of which seeks to
                   match the investment results of a particular investment
                   grade bond index through the use of index sampling
                   techniques. The Total Bond Market Portfolio seeks to
                   replicate the performance of a broad market weighted bond
                   index, while the Short-Term Bond, Intermediate-Term Bond and
                   Long-Term Bond Portfolios attempt to replicate the
                   performance of market weighted bond indexes with prescribed
                   maturity standards. There is no assurance that any of the
                   Fund's Portfolios will achieve its stated objective.

BALANCED INDEX
FUND
THE FUND SEEKS
TO TRACK THE
WILSHIRE 5000 AND THE
LEHMAN BROTHERS
INDEX              The objective of the Fund is to replicate, with respect to
                   60% of its assets, the investment performance of the Wilshire
                   5000 and, with respect to 40% of its assets, the investment
                   performance of the Lehman Brothers Index. There is no
                   assurance that the Fund will achieve its stated objective.
    
 
   
                   The Wilshire 5000 consists of all U.S. common stocks that
                   trade on a regular basis on the New York and American Stock
                   Exchanges and in the NASDAQ over-the-counter market. The
                   Lehman Brothers Index measures the total return (capital
                   change plus income) provided by a universe of fixed-income
                   securities, weighted by market value. The securities included
                   in the index generally have an outstanding market value of at
                   least $25 million, are of investment grade quality and are
                   readily available in the marketplace.

INDEX TRUST
EACH PORTFOLIO SEEKS
TO MATCH THE
INVESTMENT
PERFORMANCE OF A
PARTICULAR STOCK
MARKET INDEX       The Trust consists of six Portfolios, each of which seeks to
                   provide investment results that correspond to a particular
                   stock market index. The correlation between the performance
                   of each of the Trust's Portfolios and the respective index
                   that each Portfolio attempts to match is expected to be at
                   least 0.95. The 500, Extended Market, Total Stock Market and
                   Small Capitalization Stock Portfolios attempt to replicate
                   the investment performance of broad market indexes, while the
                   Value and Growth Portfolios attempt to replicate indexes
                   which possess certain "value" and "growth" investment
                   characteristics.
    
 
                   - The 500 PORTFOLIO seeks to replicate the aggregate price
                     and yield performance of the Standard & Poor's 500
                     Composite Stock Price Index (the "S&P 500 Index"), an index
                     which emphasizes large-capitalization companies.
 
                   - The EXTENDED MARKET PORTFOLIO seeks to replicate the
                     aggregate price and yield performance of the Wilshire 4500
                     Index, an index which consists of more than 5,000 medium-
                     and small-capitalization companies that are not included in
                     the S&P 500 Index.
 
                   - The TOTAL STOCK MARKET PORTFOLIO seeks to replicate the
                     aggregate price and yield performance of the Wilshire 5000
                     Index, an index which consists of all U.S. stocks that
                     trade on a regular basis on either the New York or American
                     Stock Exchange or the NASDAQ over-the-counter market. These
                     stocks include the large-capitalization companies of the
                     S&P 500 Index, with the exception of Royal Dutch and
                     Unilever, N.V., which trade on the New York Stock Exchange
                     as ADR's, as well as the medium- and small-capitalization
                     companies of the Wilshire 4500 Index.
 
                   - The SMALL CAPITALIZATION STOCK PORTFOLIO seeks to replicate
                     the aggregate price and yield performance of the Russell
                     2000 Small Stock Index (the "Russell 2000"), a broadly
                     diversified small-capitalization stock index consisting of
                     approximately 2,000 common stocks.

                   - The VALUE PORTFOLIO seeks to replicate the aggregate price
                     and yield performance of the S&P/BARRA Value Index, an
                     index which includes stocks in the S&P 500 Index with lower
                     than average ratios of market price to book value. These
                     types of stocks are often referred to as "value" stocks.
 
                   - The GROWTH PORTFOLIO seeks to replicate the aggregate price
                     AND yield performance of the S&P/BARRA Growth Index, an
                     index which includes stocks in the S&P 500 Index with
                     higher than average ratios of market price to book value.
                     These types of stocks are often referred to as "growth"
                     stocks.
 
                   There is no assurance that the Portfolios will achieve their
                   stated objectives.

INTERNATIONAL
EQUITY INDEX FUND
EACH PORTFOLIO SEEKS
TO MATCH THE
INVESTMENT
PERFORMANCE OF ITS
RESPECTIVE INDEX   The Fund consists of three Portfolios, each of which seeks to
                   match the investment results of a Morgan Stanley Capital
                   International Index. The European Portfolio seeks to
                   replicate the aggregate price and yield performance of the
                   Morgan Stanley Capital International-Europe (Free) Index
                   ("MSCI-Europe (Free)"), a diversified, capitalization
                   weighted index comprised of companies located in fourteen
                   European countries. The Pacific Portfolio seeks to replicate
                   the aggregate price and yield performance of the Morgan
                   Stanley Capital International-Pacific (Free) Index
                   ("MSCI-Pacific"), a diversified, capitalization weighted
                   index consisting of companies located in Australia, Japan,
                   Hong Kong, New Zealand, Singapore and Malaysia. There is no
                   assurance that either Portfolio will achieve its stated
                   objective.
    
 
   
                   By holding both the European and Pacific Portfolios in
                   appropriate proportions, an investor may create an aggregate
                   portfolio designed to approximate the total return (income
                   plus capital change) of the Morgan Stanley Capital
                   International-Europe, Australia and Far East (Free) Index
                   ("EAFE Free"), a broadly diversified international index
                   consisting of more than 1,000 equity securities of companies
                   located outside of the United States. As of December, 31,
                   1994, the MSCI-Pacific (Free) Index represented approximately
                   55% of the market capitalization of EAFE (Free), while the
                   MSCI-Europe (Free) Index represented the remaining 45%.
    
 
   
                   The Emerging Markets Portfolio seeks, with respect to 95% of
                   assets, to provide investment results that parallel the
                   Morgan Stanley Capital International ("MSCI")-Select Emerging
                   Markets Free Index ("Index"). The MSCI-Select Emerging
                   Markets Free Index is a diversified index consisting of
                   common stocks located in 12 countries. This Index provides
                   broader diversification and more liquidity than other
                   "published" emerging markets indexes and also takes into
                   consideration the trading capabilities of foreigners in
                   emerging stock market countries.
    
 
                   The Fund is neither sponsored by nor affiliated with Morgan
                   Stanley Capital International.
 
                   The investment objectives of each Portfolio of Vanguard Bond
                   Index Fund and Vanguard Index Trust are fundamental and so
                   cannot be changed without the approval of a majority of a
                   Portfolio's shareholders.
 
                   The investment objectives of Vanguard Balanced Index Fund and
                   each Portfolio of Vanguard International Equity Index Fund
                   are not fundamental and may be changed by the Board of
                   Directors without shareholder approval. However, shareholders
                   would be notified prior to a material change.

EACH FUND USES
A "PASSIVE"
INVESTMENT
APPROACH           The Funds are not managed according to traditional methods of
                   "active" investment management, which involve the buying and
                   selling of securities based upon economic, financial and
                   market analysis and investment judgment. Instead, the Funds,
                   utilizing a "passive" or indexing investment approach,
                   attempt to approximate the investment performance of their
                   respective indexes through statistical procedures. The Funds
                   are managed without regard to tax ramifications.
 
                   The investment policies of the Funds are not fundamental and
                   so may be changed by the Board of Directors without

BOND INDEX FUND
EACH PORTFOLIO INVESTS
IN FIXED INCOME
SECURITIES         Each Portfolio will invest in a group of fixed-income
                   securities selected from its respective index which, when
                   taken together, are expected to perform similarly to the
                   index as a whole. This sampling technique is expected to
                   enable each Portfolio to track the dividend income and price
                   movements of its respective index, while minimizing
                   brokerage, custodial and accounting costs.
    
 
   
                   The TOTAL BOND MARKET PORTFOLIO will invest in a portfolio of
                   fixed-income securities selected to match the Lehman Brothers
                   Aggregate Bond Index (the "Aggregate Bond Index"). The
                   Aggregate Bond Index is a broad market weighted index which
                   encompasses four major classes of investment grade
                   fixed-income securities in the United States: U.S. Treasury
                   and agency securities, corporate bonds, international
                   (dollar-denominated) bonds, and mortgage-backed securities,
                   with maturities greater than one year.
    
 
   
                   The SHORT-TERM BOND PORTFOLIO will invest in a portfolio of
                   fixed-income securities selected to match the Lehman Brothers
                   Mutual Fund Short (1-5) Government/Corporate Index (the
                   "Short-Term Index"). The Short-Term Index is a market
                   weighted index which encompasses three major classes of
                   investment grade fixed-income securities: U.S. Treasury,
                   agency securities and corporate bonds, and international
                   (dollar-denominated) bonds, all with maturities between 1 and
                   5 years.
    
 
   
                   The INTERMEDIATE-TERM BOND PORTFOLIO will invest in a
                   portfolio of fixed-income securities selected to match the
                   Lehman Brothers Mutual Fund Intermediate (5-10)
                   Government/Corporate Index (the "Intermediate-Term Index").
                   The Intermediate-Term Index is a market weighted index which
                   encompasses three major classes of investment grade
                   fixed-income securities: U.S. Treasury and agency securities,
                   corporate bonds, and international (dollar-denominated)
                   bonds, all with maturities between 5 and 10 years.
    
 
   
                   The LONG-TERM BOND PORTFOLIO will invest in a portfolio of
                   fixed-income securities selected to match the Lehman Brothers
                   Mutual Fund Long (10+) Government/Corporate Index (the "Long-
                   Term Index"). The Long-Term Index is a market weighted index
                   which encompasses three major classes of investment grade
                   fixed-income securities: U.S. Treasury and agency securities,
                   corporate bonds, and international (dollar-denominated)
                   bonds, all with maturities greater than 10 years.
    
 
   
                   Each Portfolio will invest 80% or more of its assets in
                   securities included in its respective index. As of December
                   31, 1994, the major classes of fixed-income securities
                   represented the following proportions of the respective

                   The Portfolios of the Fund may, from time to time, substitute
                   one type of investment grade bond for another. For instance,
                   a Portfolio may hold more short-term corporate bonds (fewer
                   short U.S. Treasury bonds) than represented in the Index so
                   as to increase income. This corporate substitution strategy
                   will entail the assumption of additional credit risk;
                   however, substantial diversification within the corporate
                   sector should moderate issue-specific credit risk. In
                   addition, current investment policy restricts corporate
                   substitutions to issues with less than 4 years remaining to
                   maturity and in aggregate no more than 15% of net assets.
                   Overall, credit risk is expected to be very low for each of
                   the Portfolios.
 
   
                   Fixed-income securities will be primarily of investment grade
                   quality-- i.e., those rated at least Baa3 by Moody's
                   Investors Service, Inc. or BBB- by Standard & Poor's
                   Corporation. Securities rated Baa or BBB are considered as
                   medium grade obligations. Interest payments and principal are
                   regarded as adequate for the present but certain protective
                   elements found in higher rated

                   bonds may be lacking. Such bonds lack outstanding investment
                   characteristics and, in fact, have speculative
                   characteristics as well.
 
   
                   In its efforts to duplicate the investment performance of the
                   Index, each Portfolio will invest in fixed-income securities
                   approximating its relative proportion of the Index's total
                   market value. For the Total Bond Market Portfolio, these
                   investments will include U.S. Treasury and agency securities,
                   mortgage-backed securities and corporate and international
                   (dollar-denominated) bonds. For the Short-Term Bond,
                   Intermediate-Term Bond and Long-Term Bond Portfolios, these
                   investments include U.S. Treasury and agency securities,
                   corporate debt and international (dollar- denominated) debt.
                   The Portfolios may invest in U.S. Treasury bills, notes and
                   bonds and other "full faith and credit" obligations of the
                   U.S. Government. The Portfolios may also invest in U.S.
                   Government agency securities, which are debt obligations
                   issued or guaranteed by agencies or instrumentalities of the
                   U.S. Government. Such "agency" securities may not be backed
                   by the "full faith and credit" of the U.S. Government. Such
                   U.S. Government agencies may include the Federal Farm Credit
                   Banks, the Resolution Trust Corporation and in the case of
                   the Total Bond Market Portfolio, the Government National
                   Mortgage Association. Even though they all carry top (AAA)
                   credit ratings, "agency" obligations are not explicitly
                   guaranteed by the U.S. Government and so are perceived as
                   somewhat riskier than comparable Treasury bonds.
    
 
                   Each Portfolio may also invest up to 20% of its assets in
                   short-term money market instruments, and may invest in bond
                   (interest rate) futures contracts and options to a limited
                   extent. Such securities will be held only to invest
                   uncommitted cash balances, to maintain liquidity to meet
                   shareholder redemptions, or to minimize trading costs. The
                   Portfolios will not invest in such securities as part of a
                   temporary defensive strategy (such as altering the aggregate
                   maturity of a Portfolio) to protect the Fund against
                   potential bond market declines. Each Portfolio intends to
                   remain fully invested, to the extent practicable, in a pool
                   of securities which will duplicate the investment
                   characteristics of the respective index. See "Implementation
                   of Policies" for a description of other investment practices
                   of the Fund.

BALANCED INDEX
FUND
THE FUND INVESTS IN
STOCKS AND BONDS   Under normal circumstances, the Fund will invest 60% of its
                   net assets in a portfolio of common stocks selected to track
                   the Wilshire 5000 and 40% of its net assets in a portfolio of
                   investment-grade bonds designed to track the Lehman Brothers
                   Index. The Fund may also invest in certain short-term fixed
                   income securities as cash reserves, although cash and cash
                   equivalents are normally expected to represent less than 1%
                   of the Fund's assets.
 
                   The Fund's common stock portfolio will invest in a portfolio
                   of common stock selected to match the Wilshire 5000. The Fund
                   is expected to invest in approximately 500 of the largest
                   securities in the Wilshire 5000 as measured by market
                   capitalization and a representative sample of the remainder.
                   Typically, the Fund will hold between 950 and 1,050 stocks,
                   which are selected primarily on the basis of market
                   capitalization and industry weightings.
 
   
                   The Fund's bond portfolio will invest in a portfolio of fixed
                   income securities selected to match the Lehman Brothers
                   Index. The Fund will invest in a representative sample of
                   fixed-income securities in the Lehman Brothers Index, which,
                   taken together, are expected to perform similarly to the
                   Index.
    
 
                   The Fund may also invest up to 30% of its assets in stock or
                   bond futures contracts and options in order to invest
                   uncommitted cash balances, to maintain liquidity to meet
                   shareholder redemptions, or to minimize trading costs. The
                   Fund will not invest in futures contracts, options, or cash
                   reserves as part of a temporary defensive strategy, such as
                   lowering the Fund's investment allocation in common stocks to
                   protect against potential stock market declines. The Fund
                   intends to remain fully invested, to the extent practicable,
                   in a pool of securities which will duplicate the investment
                   characteristics of the Wilshire 5000 and Lehman Brothers
                   Indexes. See "Implementation of Policies" for a description
                   of these and other investment practices of the Fund.

INDEX TRUST
ALL SIX PORTFOLIOS
INVEST IN
COMMON STOCKS      The 500, Value, and Growth Portfolios each invest in all the
                   stocks included in each of their respective indexes in
                   approximately the same proportion as they are represented in
                   the index. The Extended Market, Total Stock Market, and Small
                   Capitalization Stock Portfolios invest in statistically
                   selected samples of the stocks included in each of their
                   respective indexes. This sampling technique is expected to
                   enable each portfolio to track the price movements of its
                   respective index, while minimizing the brokerage, custodial,
                   and accounting costs.
 
                   The 500 PORTFOLIO invests in all 500 stocks in the S&P 500
                   Index in approximately the same proportions as they are
                   represented in the Index.
 
                   The EXTENDED MARKET PORTFOLIO invests in a statistically
                   selected sample of the more than 5,000 stocks included in the
                   Wilshire 4500 Index. Typically, the Portfolio invests in
                   1,400 to 1,700 stocks. Stocks are selected for inclusion in
                   the Portfolio based primarily on market capitalization and
                   industry weightings. The Portfolio is constructed to have
                   aggregate investment characteristics similar to those of the
                   Wilshire 4500 Index.
 
                   The TOTAL STOCK MARKET PORTFOLIO invests in a statistically
                   selected sample of the more than 6,000 stocks included in the
                   Wilshire 5000 Index. Typically, the Portfolio invests in
                   approximately 1,700 stocks. Stocks are selected for inclusion
                   in the Portfolio based primarily on market capitalization and
                   industry weightings. The Portfolio is constructed to have
                   aggregate investment characteristics similar to those of the
                   Wilshire 5000 Index.
 
                   The SMALL CAPITALIZATION STOCK PORTFOLIO invests in a
                   statistically selected sample of the approximately 2,000
                   stocks included in the Russell 2000 Index. Typically, the
                   Portfolio invests in approximately 1,000 stocks. Stocks are
                   selected for inclusion in the Portfolio based on their
                   contribution to the Portfolio's market capitalization,
                   industry weightings and other fundamental characteristics
                   such as price-earnings ratios, dividend yields, price-to-book
                   ratios and financial leverage. The stocks held by the
                   Portfolio are weighted to make the Portfolio's aggregate
                   investment characteristics similar to those of the Russell
                   2000 Index as a whole.
 
   
                   The VALUE PORTFOLIO invests in all of the common stocks
                   included in the S&P/BARRA Value Index in approximately the
                   same proportions as they are represented in the Index. As of
                   December 31, 1994, the S&P/BARRA Value Index included 318 of
                   the stocks that make up the S&P 500 Index, and 50% of the
                   total market value of the Index.
    
 
   
                   The GROWTH PORTFOLIO invests in all of the common stocks
                   included in the S&P/BARRA Growth Index in approximately the
                   same proportions as they are represented in the Index. As of
                   December 31, 1994, the S&P/BARRA Growth Index included 182 of
                   the stocks that make up the S&P 500 Index, and 50% of the
                   total market value of the Index.
    
 
ALL SIX PORTFOLIOS
ATTEMPT TO REMAIN
FULLY INVESTED     Each Portfolio attempts to remain fully invested in common
                   stocks. Under normal circumstances each Portfolio will invest
                   at least 95% of its assets in the common stocks of its
                   respective index and futures contracts and options. Each
                   Portfolio may invest in certain short-term fixed income
                   securities as cash reserves, although cash or cash
                   equivalents are normally expected to represent less than 1%
                   of each Portfolio's assets. Each Portfolio may also invest up
                   to 20% of its assets in stock futures contracts and options
                   in order to invest uncommitted cash balances, to maintain
                   liquidity to meet shareholder redemptions, or to minimize
                   trading costs. The Portfolios will not invest in cash

                   defensive strategy, such as lowering a Portfolio's investment
                   in common stocks to protect against potential stock market
                   declines. The Portfolios intend to remain fully invested, to
                   the extent practicable, in a pool of securities which will
                   duplicate the investment characteristics of their respective
                   indexes. See "Implementation of Policies" for a description

INTERNATIONAL STOCKS
                   Each of the three Portfolios invest in statistically selected
                   samples of the stocks included in each of their respective
                   indexes. This sampling technique is expected to enable each
                   portfolio to track the price movements of its respective
                   index, while minimizing the brokerage, custodial, and
                   accounting costs.
 
   
                   The EUROPEAN PORTFOLIO invests in a statistically selected
                   sample of approximately 545 stocks included in the
                   MSCI-Europe (Free) Index, an index of equity securities of
                   companies located in fourteen European countries. Three
                   countries, the United Kingdom, Germany and France, dominate
                   MSCI-Europe (Free), with 35%, 14%, and 13% of the market
                   capitalization of the Index, respectively, as of December 31,
                   1994. The 11 other countries are individually much less
                   significant to the Index and, consequently, the Portfolio.
                   The "Free" Index includes only shares that U.S. investors are
                   "free" to purchase.
    
 
   
                   The PACIFIC PORTFOLIO invests in a statistically selected
                   sample of the more than 440 stocks included in the
                   MSCI-Pacific (Free) Index, an index of equity securities of
                   Pacific Basin companies. The MSCI-Pacific (Free) Index is
                   dominated by the Japanese stock market, which represented 83%
                   of the market capitalization of the Index as of December 31,
                   1994.
    
 
                   The European and Pacific Portfolios are each expected to
                   invest in approximately 250 stocks or more. Stocks are
                   selected for inclusion in each Portfolio based on country,
                   market capitalization, industry weightings, and fundamental
                   characteristics such as return variability, earnings
                   valuation, and yield. Each of the two Portfolios is
                   constructed to have aggregate investment characteristics
                   similar to those of its respective index. In order to
                   parallel the performance of its respective index, each
                   Portfolio will invest in each country in approximately the
                   same percentage as the country's weight in the index.
 
   
                   Each of the two Portfolio's policy is to remain fully
                   invested in common stocks. Under normal circumstances at
                   least 80% of the assets of each Portfolio will be invested
                   in stocks that are represented in its respective index. Each
                   Portfolio may invest in certain short-term fixed income
                   securities such as cash reserves, although cash or cash
                   equivalents are normally expected to represent less than 1%
                   of each Portfolio's assets. Each Portfolio may also invest
                   up to 50% of its assets in stock futures contracts, options,
                   and warrants in order to invest uncommitted cash balances,
                   maintain liquidity to meet shareholder redemptions, or
                   minimize trading costs. Any investment in futures contracts,
                   options, warrants, convertible securities or swap agreements
                   over 20% of each Portfolio's assets would be made in
                   emergency situations, for short-term purposes.
    
 
                   The European and Pacific Portfolios will not invest in cash
                   reserves, futures contracts, options or warrants as part of a
                   temporary defensive strategy, such as lowering a Portfolio's
                   investment in common stocks, to protect against potential
                   stock market declines. The Portfolios intend to remain fully
                   invested, to the extent practicable, in a pool of securities
                   which will approximate the investment characteristics of
                   their respective indexes. The Portfolios may also enter into
                   forward foreign currency exchange contracts in order to
                   maintain the same currency exposure as their respective
                   indexes, but not as part of a defensive strategy to protect
                   against fluctuations in exchange rates.
 
   
                   The EMERGING MARKETS PORTFOLIO invests in a statistically
                   selected sample of approximately 300 stocks included in the
                   MSCI-Select Emerging Markets Free Index, an index of equity
                   securities of companies located in the countries of 12
                   emerging markets. Three countries, Malaysia, Brazil and Hong
                   Kong represent a majority of the MSCI-Select Emerging Markets
                   Free Index, with 19%, 18% and 13% of the market
                   capitalization of the Index, respectively, as of December 31,
                   1994.
    
 
                   The Index includes only shares that U.S. investors are "free"
                   or allowed by law, to purchase and sell and that have
                   sufficient trading liquidity.
 
                   The Portfolio is expected to invest in approximately 300
                   stocks. Stocks are selected for inclusion in the Portfolio in
                   order to form a statistically representative sample
                   corresponding to the MSCI-Select Emerging Markets Free Index.
                   The Portfolio is constructed to have aggregate investment
 
                                       16

                   characteristics (based on country, market capitalization and
                   industry weightings), fundamental characteristics (such as
                   return variability, earnings valuation and yield) and
                   liquidity measures, similar to those of its Index.
 
                   The Portfolio's policy is to remain 95% invested in common
                   stocks. The remaining 5% of the Portfolio will be invested in
                   cash reserves in order to maintain a higher degree of
                   portfolio liquidity to meet daily redemption requests.
 
   
                   Under normal circumstances at least 80% of the assets of the
                   Portfolio will be invested in stocks that are represented in
                   the Index and futures contracts and options thereon. The
                   Portfolio may also invest up to 50% of its assets in stock
                   futures contracts, options, warrants, convertible securities
                   or swap agreements in order to invest uncommitted cash
                   balances, maintain liquidity to meet shareholder redemptions,
                   or minimize trading costs. Any investment in futures
                   contracts, options, warrants, convertible securities or swap
                   agreements over 20% of the Portfolio's assets would be made
                   in emergency situations, for short-term purposes.
    
 
                   See "Implementation of Policies" for a description of these
                   and other investment practices of the Portfolios.

INVESTMENT
RISKS
EACH PORTFOLIO IS
SUBJECT TO MARKET RISK
                   As mutual funds investing primarily in common stocks,
                   Vanguard Balanced Index Fund and the Portfolios of Vanguard
                   Index Trust and Vanguard International Equity Index Fund are
                   subject to market risk--i.e., the possibility that common
                   stock prices will decline over short or even extended
                   periods. Both U.S. and foreign stock markets tend to be
                   cyclical, with periods when stock prices generally rise and
                   periods when prices generally decline.
 
   
                   Common stocks, as measured by the S&P 500 Index, have
                   provided annual total returns (capital appreciation plus
                   dividend income), averaging +10.7% for all 10-year periods
                   from 1926 to 1994. Average return may not be useful for
                   forecasting future returns in any particular period, as stock
                   returns are quite volatile from year to year.

INDEX TRUST
THE EXTENDED MARKET,
TOTAL STOCK MARKET
AND SMALL
CAPITALIZATION STOCK
PORTFOLIOS MAY 
EXHIBIT GREATER 
VOLATILITY         Historically, medium- and small-capitalization stocks have
                   been more volatile in price than the larger-capitalization
                   stocks included in the S&P 500 Index. Among the reasons for
                   the greater price volatility of these securities are the less
                   certain growth prospects of smaller firms, the lower degree
                   of liquidity in the markets for such stocks, and the greater
                   sensitivity of medium- and small-size companies to changing
                   economic conditions. Besides exhibiting greater volatility,
                   medium- and small-size company stocks may, to a degree,
                   fluctuate independently of larger company stocks. Medium- and
                   small-size company stocks may decline in price as large
                   company stocks rise, or rise in price as large company stocks
                   decline. Medium- and small-size company stocks constitute the
                   investments of the Extended Market Portfolio while the Small
                   Capitalization Stock Portfolio is composed primarily of
                   small-size company stocks. Investors in the Portfolios should
                   therefore expect that the Extended Market and Small
                   Capitalization Stock Portfolios will be more volatile than,
                   and may fluctuate independently of, the 500 Portfolio.
 
   
                   Similarly, medium- and small-size company stocks constituted
                   approximately 31% of the net assets of the Total Stock Market
                   Portfolio on December 31, 1994. Investors in the Portfolio
                   should therefore anticipate somewhat greater price volatility
                   in the Total Stock Market Portfolio relative to the 500
                   Portfolio.
    
 
THE VALUE AND
GROWTH PORTFOLIOS
MAY FLUCTUATE
INDEPENDENTLY      Stocks that emphasize particular investment characteristics,
                   such as "value" and "growth," may fluctuate divergently from
                   the broad market as represented by the S&P 500 Index, and may
                   also demonstrate greater volatility over short or extended
                   periods relative to the broad market.
 
                   The S&P/BARRA Value Index maintains a lower price-to-book
                   ratio and historically has had a higher yield than the S&P
                   500 Index, while the S&P/BARRA Growth Index maintains a
                   higher price-to-book and historically has had a lower yield
                   than the S&P 500 Index. Because of these investment
                   characteristics, the S&P/BARRA Value Index has exhibited
                   somewhat less short-term volatility than the S&P 500 Index,
                   while the S&P/BARRA Growth Index has displayed somewhat
                   greater short-term

                   volatility than the S&P 500 Index from 1975 through 1994.
                   However, as stated above, both Indexes may be more volatile
                   than the S&P 500 Index over short or extended periods. The
                   Indexes have been in existence since May, 1992. Historical
                   performance data was generated by BARRA by constructing the
                   S&P/BARRA Value and Growth Indexes from actual S&P 500 Index
                   holdings.

VOLATILITY THAN
U.S. STOCKS        Investments in foreign stock markets can be as volatile, if
                   not more volatile, than investments in U.S. markets.
 
   
                   The MSCI-Europe Index has provided annual total returns,
                   averaging +14.2% for all 10-year periods from 1970-1994, and
                   the MSCI-Pacific Index has provided annual total returns,
                   averaging +18.0% during the same periods. By comparison, the
                   average annual total return of U.S. stocks during this same
                   period was +10.7% (as measured by the Standard & Poor's 500
                   Composite Stock Price Index). Note, however, that the period
                   from 1970 to 1994 was a very favorable one for foreign stock
                   market investing. 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 JAPANESE STOCK
MARKET IS A MAJOR
COMPONENT OF THE
PACIFIC INDEX      Investors should realize that Japanese securities comprised
                   83% of the MSCI-Pacific Index as of December 31, 1994, and
                   that therefore stocks of Japanese companies will represent a
                   correspondingly large component of the Pacific Portfolio's
                   investment assets. Such a large investment in the Japanese
                   stock market may entail a higher degree of risk than with
                   more diversified international portfolios, especially
                   considering that by fundamental measures of corporate
                   valuation, such as its high price-earnings ratios and low
                   dividend yields, the Japanese market as a whole may appear
                   expensive relative to other world stock markets.
    
 
   
STOCKS FROM THREE
COUNTRIES DOMINATE
THE EUROPE (FREE)
INDEX              Stocks from the United Kingdom, Germany and France comprised
                   35%, 14% and 13% of the MSCI-Europe (Free) Index,
                   respectively, as of December 31, 1994. The remaining 11
                   countries in the MSCI-Europe (Free) Index have much less
                   significant capitalization weightings in the Index and will
                   therefore have much less impact on the total return of the
                   Index and the European Portfolio.
    
 
EMERGING MARKETS
MAY EXHIBIT GREATER
VOLATILITY THAN
DEVELOPED MARKETS  Emerging markets, such as those invested in by the Emerging
                   Markets Portfolio, are associated with substantial investment
                   risks. These risks include market volatility, investment
                   illiquidity, currency risk, political instability and
                   unexpected changes in economic policy including capital
                   controls, expropriation, taxes and hyper-inflation.
 
   
                   Investors should be aware that emerging markets can be
                   substantially more volatile than both U.S. and more developed
                   foreign markets. For example, from 1989-1994, the average
                   positive monthly return for the Wilshire 5000 Index, a broad
                   measure of the U.S. equity market was +2.9%. The average
                   negative monthly return for the Wilshire 5000 Index was
                   -2.7%. In contrast, from 1989-1994, the average positive
                   monthly return of the Morgan Stanley Capital International
                   Emerging Markets Free Index, a widely quoted emerging market
                   benchmark, was +5.3%; while the average negative monthly
                   return was -5.3%.
    
 
INVESTMENT ILLIQUIDITY
RISK               Volatility in emerging markets may be exacerbated by
                   illiquidity. Average daily trading volume in all of the
                   emerging markets combined is a small fraction of the average
                   daily volume of the U.S. market. Small trading volumes may
                   result in investors being forced to purchase securities at
                   substantially higher prices than the current market, or sell
                   securities at much lower prices than the current market.

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 three Portfolios are influenced by not
                   only the returns on foreign common stocks themselves, but
                   also by the returns on the currencies in which the stocks
                   are denominated. Currency risk is the risk that changes in
                   foreign exchange rates will affect, favorably or
                   unfavorably, the value of foreign securities held by a
                   Portfolio. In a period when the U.S. dollar generally rises
                   against foreign currencies, the returns on foreign stocks
                   for a U.S. investor will be diminished. By contrast, in a
                   period when the U.S. dollar generally declines, the returns
                   on foreign stocks will be enhanced. Currency risk in
                   emerging markets may be exacerbated by unexpected exchange
                   rate devaluations.
 
                   Other risks and considerations of international investing
                   include: differences in accounting, auditing and financial
                   reporting standards; generally higher transaction costs on
                   foreign portfolio transactions; small trading volumes and
                   generally lower liquidity of foreign stock markets, which may
                   result in greater price volatility; foreign withholding taxes
                   payable on a Portfolio's foreign securities, which may reduce
                   dividend income payable to shareholders; the possibility of
                   expropriation or confiscatory taxation; adverse change in
                   investment or exchange control regulations; difficulty in
                   obtaining a judgement from a foreign court; political
                   instability which could affect U.S. investment in foreign
                   countries; and potential restriction on the flow of
                   international capital.
- --------------------------------------------------------------------------------
 
BOND INDEX FUND
THE PORTFOLIOS ARE
SUBJECT TO INTEREST
RATE RISK          INTEREST RATE RISK is the potential for fluctuations in bond
                   prices due to changing interest rates. As a rule, bond prices
                   vary inversely with interest rates. If interest rates rise,
                   bond prices generally decline; if interest rates fall, bond
                   prices generally rise. In addition, for a given change in
                   interest rates, longer-maturity bonds fluctuate more in price
                   than shorter-maturity bonds. To compensate investors for
                   these larger fluctuations, longer-maturity bonds usually
                   offer higher yields than shorter-maturity bonds, other
                   factors, including credit quality, being equal.
 
   
                   These basic principles of bond prices also apply to U.S.
                   Government securities. A security backed by the "full faith
                   and credit" of the U.S. Government is guaranteed only as to
                   its stated interest rate and face value at maturity, not its
                   current market price. Just like other fixed-income
                   securities, government-guaranteed securities will fluctuate
                   in value when interest rates change.
    
 
                   The TOTAL BOND MARKET and INTERMEDIATE-TERM BOND PORTFOLIOS
                   maintain an intermediate-term average weighted maturity, and
                   are therefore subject to a moderate to high level of interest
                   rate risk. Interest rate risk for the SHORT-TERM BOND
                   PORTFOLIO should be modest. Because of the short-term average
                   weighted maturities, the Portfolio is expected to exhibit low
                   to moderate price fluctuations as interest rates change. The
                   LONG-TERM BOND PORTFOLIO is exposed to substantial interest
                   rate risk. The Portfolio is expected to have an average
                   maturity in excess of 15 years which exposes it to high to
                   very high price fluctuations due to changing interest rates.
 
THE PORTFOLIOS ARE
SUBJECT TO INCOME RISK
                   INCOME RISK is the potential for a decline in a Portfolio's
                   income due to falling market interest rates. In relative
                   terms, income risk will be higher for the Fund's shorter-term
                   Portfolios and lower for the Fund's longer-term Portfolios.
 
THE LONG-TERM BOND
PORTFOLIO IS SUBJECT TO
CALL RISK          An additional risk associated with long-term corporate bonds
                   is call risk. CALL RISK is the possibility that corporate
                   bonds held by the Portfolio will be repaid prior to maturity.
                   Call provisions, common in many corporate bonds, allow bond
                   issuers to redeem bonds prior to maturity (at a specific
                   price). When interest rates are falling, bond issuers often
                   exercise these call provisions, paying off bonds that carry
                   high stated interest rates and often issuing new bonds at
                   lower rates. For the Portfolio, the result would be that
                   bonds with high interest rates are "called" and must be
                   replaced with lower-yielding instruments. In these
                   circumstances, the income of the Portfolio would decline.
                   Reflecting these additional credit and call risks, the
                   corporate portion of the portfolio will generally offer
                   higher yields than the government portion.

THE TOTAL BOND
MARKET PORTFOLIO IS
SUBJECT TO
PREPAYMENT RISK    As a mutual fund investing a portion of its assets in
                   mortgage-backed securities (see chart on page 13), the Total
                   Bond Market Portfolio is subject to prepayment risk to a
                   limited extent. PREPAYMENT RISK is the possibility that,
                   during periods of declining interest rates, the principal
                   invested in high-yielding mortgage-backed securities will be
                   repaid earlier than scheduled, and the Fund will be forced to
                   reinvest the unanticipated payments at generally lower
                   interest rates.
    
 
   
                   Prepayment risk has two important effects on the Portfolio.
                   First, when interest rates fall and principal prepayments are
                   reinvested at lower interest rates, the income that the
                   Portfolio derives from mortgage-backed securities is reduced.
                   Second, like other fixed-income securities, mortgage-backed
                   securities generally decline in price when interest rates
                   rise. However, because of prepayment risk, mortgage-backed
                   securities (and thus in part the share price of the Portfolio
                   and the value of the Index) will not enjoy as large a gain in
                   market value as ordinary bonds when interest rates fall. In
                   part to compensate for prepayment risk, mortgage-backed
                   securities generally offer higher yields than bonds of
                   comparable credit quality and maturity.
    
 
CREDIT RISK IS EXPECTED
TO BE LOW          CREDIT RISK is the possibility that an issuer of securities
                   held by a Portfolio will be unable to make payments of either
                   interest or principal. The credit risk of a Portfolio is a
                   function of the credit quality of its underlying securities.
 
   
                   The credit quality of each Portfolio is expected to be very
                   high, and thus credit risk should be low. As of December 31,
                   1994, the average quality, as rated by Moody's Investors
                   Service, Inc., of each Portfolio's benchmark index was as
                   follows:
    
 
<TABLE>
                            <S>                                                                      <C>
                            Aggregate Bond Index....................................................  AAA

                            Long-Term Bond Index....................................................  AA1
</TABLE>
 
   
                   To a limited extent, the Portfolios are also exposed to event
                   risk, the possibility that corporate fixed-income securities
                   held by the Portfolios may suffer a substantial decline in
                   credit quality and market value due to a corporate
                   restructuring. Corporate restructurings, such as mergers,
                   leveraged buyouts, takeovers or similar events, are often
                   financed by a significant expansion of corporate debt. As a
                   result of the added debt burden, the credit quality and
                   market value of a firm's existing debt securities may decline
                   significantly. While event risk may be high for certain
                   corporate and international (dollar-denominated) securities
                   held by the Portfolios, event risk for each Portfolio in the
                   aggregate should be low because of each Portfolios
                   diversified holdings and the small percentage of the
                   Portfolio assets invested in these securities.
    
 
   
                   The corporate substitution strategy used by the Fund (see
                   discussion on page 13) will increase credit risk somewhat, as
                   short-term investment grade corporate bonds are substituted
                   for U.S. Treasury bonds and notes; however, owing to the
                   diversified nature of the Portfolios, and policies limiting
                   the maturity and maximum amount of substitutions, the overall
                   credit and event risk of the Portfolio is expected to be low.
    
 
   
NO CURRENCY RISK IN
ANY PORTFOLIO      While each of the chosen Lehman Index benchmarks do have
                   limited exposure to international bonds, there is no
                   currency risk associated with the investments since they are
                   all dollar-denominated.
    
- --------------------------------------------------------------------------------
 
WHO SHOULD
INVEST             The Funds offer investors the advantage of a "passive"
                   approach to investing. These include low investment costs,
                   exceptional diversification among a wide range of stocks and
                   bonds, minimal portfolio turnover, and relative
                   predictability. Unlike other mutual funds, which generally
                   attempt to "beat" market averages with often unpredictable
                   results, the Portfolios of the Funds seek to "match" the
                   performance of their underlying indexes and thus are expected
                   to provide a highly predictable return relative to these
                   benchmarks.
 
                   However, shareholders should expect to be fully exposed to
                   the market risks inherent in investing in stocks and bonds.
                   As the prices of stocks and bonds may be volatile, only
                   investors able to tolerate
 
                                       20
<PAGE>   79
 
                   short-term, possibly substantial fluctuations in the value of
                   their investment, brought about by generally declining stock
                   or bond prices, should contemplate an investment in the
                   Funds.
 
                   Investors may wish to reduce the potential risk of investing
                   in a Portfolio by purchasing shares on a regular, periodic
                   basis (dollar-cost averaging) rather than making an
                   investment in one lump sum.
 
                   The Funds are intended to be a long-term investment vehicle
                   and not designed to provide investors with a means of
                   speculating on short-term market movements. Investors who
                   engage in excessive account activity generate additional
                   costs which are borne by all shareholders. In order to
                   minimize such costs the Funds have adopted the following
                   policies. The Funds reserve 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 Funds have adopted exchange
                   privilege limitations as described in the section "Exchange
                   Privilege Limitations." Finally, the Funds reserve the right
                   to suspend the offering of their shares.
 
                   Investors should not consider an investment in any one Fund a
                   complete investment program, but should maintain holdings of
                   securities with different risk characteristics -- including
                   common stocks, bonds and money market instruments.

BOND INDEX FUND
INVESTORS SEEKING TO
PARTICIPATE IN THE
"BOND MARKET" AS A
WHOLE OR ITS VARIOUS
MATURITY SEGMENTS  The Portfolios are designed for individual and institutional
                   investors seeking well-diversified, low-cost ways to
                   participate in the U.S. fixed-income markets. The Portfolios
                   will be essentially fully invested at all times. Because the
                   Total Bond Market Portfolio will represent all major sectors
                   of the investment grade fixed-income securities market, the
                   Portfolio is a suitable vehicle for those investors seeking
                   ownership in the "bond market" as a whole, without regard to
                   particular sectors. The Short-Term Bond, Intermediate-Term
                   Bond and Long-Term Bond Portfolios are suitable vehicles for
                   those investors seeking ownership in specific maturity
                   segments of the "bond market." Each Portfolio concentrates on
                   bonds of various maturities as illustrated in the chart on
                   page 13. Because of the risks associated with bond
                   investments, each 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 bond market
                   movements.
    
 
   
                   As with all longer-term, fixed-income investments, the share
                   price of the Total Bond Market, Intermediate-Term Bond and
                   Long-Term Bond Portfolios will vary, with the Long-Term Bond
                   Portfolio expected to exhibit the greatest volatility. Share
                   price volatility should be significantly less for the
                   Short-Term Bond Portfolio. Credit risk should be minimal for
                   each Portfolio. The investment risks are described on page
                   19.
    
 
   
                   The Portfolios are also suitable for those investors with
                   common stock holdings who are seeking a complementary
                   fixed-income investment to create a more balanced asset mix.
                   Because of potential share price fluctuations, the Portfolios
                   may be inappropriate for investors who have short-term
                   objectives or who require stability of principal.

BALANCED INDEX
FUND
INVESTORS SEEKING A
BALANCE BETWEEN
CURRENT INCOME AND
CAPITAL GROWTH     The Fund is designed for conservative investors seeking a
                   long-term investment offering both current income and the
                   potential for capital growth. By balancing its investments
                   among common stocks and bonds, the Fund is expected to
                   provide lower investment risk and share price volatility than
                   a mutual fund which invests exclusively in common stocks. The
                   balanced investment approach of the Fund tends to reduce
                   exposure to stock and bond market risks; it does not
                   eliminate them. The Fund is thus suitable for investors who
                   wish to gain exposure to the potential capital growth
                   provided by the stock market, while limiting investment risk.
                   Such a balanced investment program might be particularly
                   well-suited to long-term investment objectives such as
                   retirement savings.

INDEX TRUST
LONG-TERM INVESTORS
SEEKING A "PASSIVE"
APPROACH FOR INVESTING
IN COMMON STOCKS   All six Portfolios of the Trust are designed for long-term
                   investors seeking the advantages of investing in a
                   diversified portfolio of common stocks.
    
 
                   Four Portfolios of the Trust provide a vehicle for investing
                   in a broad market index:
 
                   - The 500 PORTFOLIO is designed for investors seeking to
                     replicate the total return of the S&P 500 Index, an index
                     emphasizing large capitalization common stocks.
 
   
                   - The EXTENDED MARKET PORTFOLIO is designed for investors
                     seeking to replicate the total return of the Wilshire 4500
                     Index, an index consisting of small- and
                     medium-capitalization companies.
    
 
                   - The TOTAL STOCK MARKET PORTFOLIO is designed for investors
                     seeking to replicate the total return of the Wilshire 5000
                     Index, an index consisting of all U.S. stocks that trade on
                     a regular basis on either the New York or American Stock
                     Exchange or the NASDAQ over-the-counter market. The Total
                     Stock Market Portfolio will therefore reflect the
                     performance of the entire U.S. stock market.
 
                   - The SMALL CAPITALIZATION STOCK PORTFOLIO is designed for
                     investors seeking to replicate the total return of the
                     Russell 2000 Small Stock Index, an index consisting of
                     approximately 2,000 small-capitalization stocks.
 
                   Two Portfolios are designed for investors seeking to
                   emphasize certain investment characteristics while continuing
                   to utilize a "passive" investment approach:
 
                   - The VALUE PORTFOLIO is designed for investors seeking to
                     replicate the total return of the S&P/BARRA Value Index, an
                     index consisting of companies of the S&P 500 Index with
                     lower than average market price to book value ratios. Such
                     a "value-oriented" Portfolio may be appropriate for more
                     conservative stock market investors who are seeking higher
                     dividend income and somewhat below average stock market
                     volatility.
 
                   - The GROWTH PORTFOLIO is designed for investors seeking to
                     replicate the total return of the S&P/BARRA Growth Index,
                     an index consisting of companies of the S&P 500 Index with
                     higher than average market price to book value ratios. Such
                     a "growth-oriented" Portfolio may be appropriate for
                     investors who have little need for current dividend income
                     and who can tolerate somewhat above average stock market
                     volatility.
 
                   Taken together in appropriate proportions, the Value and
                   Growth Portfolios are expected to approximate the total
                   returns achieved by the 500 Portfolio.

INTERNATIONAL
EQUITY INDEX FUND
LONG-TERM INVESTORS
SEEKING TO INVEST
IN INTERNATIONAL
COMMON STOCKS      The Portfolios are designed for investors who seek a low-cost
                   "passive" approach for investing in a broadly diversified
                   portfolio of international common stocks. Unlike other equity
                   mutual funds, which generally seek to "beat" market averages
                   with often unpredictable results, the Portfolios of the Fund
                   seek to "match" their respective indexes and thus are
                   expected to provide a predictable return relative to their
                   respective benchmarks. In particular, the European Portfolio
                   is designed for investors seeking to approximate the total
                   investment results (before fund expenses and withholding
                   taxes) of the MSCI-Europe (Free) Index, a diversified index
                   of European common stocks. The Pacific Portfolio is designed
                   for investors seeking to approximate the total investment
                   results (before fund expenses and withholding taxes) of the
                   MSCI-Pacific (Free) Index, a diversified index of Pacific
                   Basin common stocks.
    
 
   
                   The European and Pacific Portfolios are also suitable for
                   investors seeking to create a portfolio which parallels the
                   performance of the MSCI-EAFE (Free) Index, a broadly
                   diversified index consisting of over 1,000 international
                   equity securities. By investing in the two portfolios in the
                   appropriate percentages (55% in the Pacific Portfolio and 45%
                   in the European Portfolio as of December 31, 1994), a
                   portfolio approximating the investment characteristics of
                   EAFE (Free) may be created.

                   The Emerging Markets Portfolio is designed for investors
                   seeking to approximate the total investment results (before
                   fund expenses and withholding taxes) of the MSCI-Select
                   Emerging Markets Free Index, a diversified index of common
                   stocks of emerging market countries.
- --------------------------------------------------------------------------------
 
IMPLEMENTATION
OF POLICIES        The Portfolios follow a variety of investment practices in an
                   effort to duplicate the total return of their respective
                   indexes.
- --------------------------------------------------------------------------------
 
   
BOND INDEX FUND
THE PORTFOLIOS INVEST
IN FIXED INCOME
SECURITIES         Each Portfolio will invest at least 80% or more of its assets
                   in securities included in its benchmark Index. The Indexes
                   measure the total investment return (capital change plus
                   income) provided by a universe of fixed-income securities,
                   weighted by the market value outstanding of each security.
                   The securities included in each Index generally meet the
                   following criteria, as defined by Lehman Brothers: an
                   outstanding market value of at least $100 million; and
                   investment grade quality -- i.e., rated a minimum of Baa by
                   Moody's Investors Service, Inc. or BBB by Standard & Poor's
                   Corporation. The maturities of securities included in each
                   index will vary as described on page 13.
    
 
THE PORTFOLIOS USE A
"SAMPLING" TECHNIQUE
                   The Portfolios will be unable to hold all of the individual
                   issues which comprise the Indexes because of the large number
                   of securities involved. Instead, each Portfolio will hold a
                   representative sample of the securities in its respective
                   Index, selecting one or two issues to represent entire
                   "classes" or types of securities in the Index. Each Portfolio
                   will be constructed so as to match the composition of its
                   benchmark index as described below.
 
                   At the broadest level, each Portfolio will seek to hold
                   securities which reflect the weighting of the major asset
                   classes in its respective index. For the Total Bond Market
                   Portfolio, these classes include U.S. Treasury and agency
                   securities, corporate bonds, and mortgage-backed securities.
                   For the Short-Term Bond, Intermediate-Term Bond and Long-Term
                   Bond Portfolios, the two major classes of securities include
                   U.S. Treasury and agency securities and corporate bonds.
 
                   Such a sampling technique is expected to be an effective
                   means of substantially duplicating the income and capital
                   returns provided by each Index. Over time, the correlation
                   between the performance of the Fund and the Index is expected
                   to be 0.95 or higher. A correlation of 1.00 would indicate
                   perfect correlation, which would be achieved when the net
                   asset value of a Portfolio, including the value of its
                   dividend and capital gain distributions, increases or
                   decreases in exact proportion to changes in the Index.
                   Because the Portfolios of the Fund incur operating expenses,
                   as opposed to their respective indexes, which do not, a
                   perfect correlation of 1.00 is unlikely to be achieved.
 
   
THE TOTAL BOND
MARKET PORTFOLIO MAY
INVEST IN MORTGAGE-
BACKED SECURITIES  As part of its effort to duplicate the investment performance
                   of its Index, the Total Bond Market Portfolio may invest in
                   mortgage-backed securities. Mortgage-backed securities
                   represent an interest in an underlying pool of mortgages.
                   Unlike ordinary fixed-income securities, which generally pay
                   a fixed rate of interest and return principal upon maturity,
                   mortgage-backed securities repay both interest income and
                   principal as part of their periodic payments. Because the
                   mortgages underlying mortgage-backed certificates can be
                   prepaid at any time by homeowners or corporate borrowers,
                   mortgage-backed securities give rise to certain unique
                   "prepayment" risks. See "Investment Risks."
    
 
                   The Total Bond Market Portfolio may purchase mortgage-backed
                   securities issued by the Government National Mortgage
                   Association (GNMA), the Federal Home Loan Mortgage
                   Corporation (FHLMC), the Federal National Mortgage
                   Association (FNMA), and the Federal Housing Authority (FHA).
                   GNMA securities are guaranteed by the U.S. Government as to
                   the timely payment of principal and interest; securities from
                   other Government-sponsored entities are generally not secured
                   by an explicit pledge of the U.S. Government. The Portfolio
                   may also invest in conventional mortgage securities, which
                   are packaged by private corporations and are not guaranteed
                   by the U.S. Government. Mortgage securities that are
                   guaranteed by the U.S. Government are guaranteed only as to
                   the timely payment of principal and interest. The market
                   value of such securities is not guaranteed and may fluctuate.

BALANCED INDEX
FUND
THE FUND INVESTS IN
A SAMPLE OF ALL U.S.
COMMON STOCKS      The Fund's common stock investments will be selected from
                   securities included in the Wilshire 5000, an index of all
                   regularly and publicly traded U.S. common stocks that trade
                   on the New York and American Stock Exchanges and in the
                   NASDAQ over-the-counter market. Approximately 6,000 stocks,
                   including large-, medium-, and small-capitalization
                   companies, are included in the Wilshire 5000, which serves as
                   a proxy for the complete U.S. stock market.
    
 
                   Under normal circumstances, the Fund will invest 60% of its
                   net assets in common stocks included in the Wilshire 5000. In
                   an effort to replicate the investment performance of the
                   Wilshire 5000, the Fund's common stock holdings will include
                   approximately 500 of the largest market capitalization stocks
                   in the Index and an additional representative sample of the
                   remaining stocks. The high transaction costs and illiquidity
                   of many of the smaller stocks in the Wilshire 5000 make
                   complete replication of the Index's holding impractical.
 
COMMON STOCKS ARE
SELECTED USING
OPTIMIZATION
TECHNIQUES ("PORTFOLIO
OPTIMIZATION")     The stocks of the Wilshire 5000 included in the Fund are
                   selected using a statistical technique known as
                   "optimization." This process selects stocks for the Fund so
                   that various industry weightings, market capitalizations, and
                   fundamental characteristics (e.g., price-to-book, price-to-
                   earnings, and debt-to-asset ratios, as well as dividend
                   yields) match those of the Wilshire 5000. For instance, if
                   10% of the capitalization of the Wilshire 5000 consists of
                   utility companies with relatively large market
                   capitalizations, then the Fund's stock holdings are
                   constructed so that approximately 10% of the Fund's stocks
                   represent utilities with relatively large capitalizations.
 
                   The Fund is not sponsored, endorsed, sold or promoted by
                   Wilshire Associates. Wilshire(R) and Wilshire 5000(R) are
                   registered service marks of Wilshire Associates.
 
   
THE FUND INVESTS IN A
SAMPLE OF ALL U.S.
INVESTMENT GRADE DEBT
                   Under normal circumstances, the Fund will invest 40% of its
                   net assets in fixed income securities included in the Lehman
                   Brothers Index, an index of U.S. investment-grade,
                   fixed-income securities. More than 4,500 individual bond
                   issues, including U.S. Treasury and Government agency
                   securities, corporate debt obligations, and mortgage-backed
                   securities are included in the Lehman Brothers Index.
    
 
                   The securities included in the Lehman Brothers Index in which
                   the Fund may invest generally meet the following criteria, as
                   defined by Lehman Brothers: an effective maturity of not less
                   than one year; an outstanding market value of at least $50
                   million; investment grade quality--i.e., rated a minimum of
                   Baa by Moody's Investors Service, Inc. or BBB by Standard &
                   Poor's Corporation; and general availability in the
                   marketplace. If a security held in the Fund's portfolio is
                   downgraded to a rating below these minimum standards, the
                   Fund may continue to hold it until such time as the adviser
                   deems it most advantageous to dispose of the security.
 
   
BONDS ARE SELECTED
USING A STRATIFIED
SAMPLING TECHNIQUE The large number of issues in the Index makes it impractical
                   for the Fund to hold all of the individual issues which
                   comprise the Index. Instead, the Fund will attempt to
                   replicate the investment performance of the Lehman Brothers
                   Index by holding a representative sample of the securities in
                   the Index. In choosing a representative sample of bond
                   investments from the Lehman Brothers Index, the Fund utilizes
                   a "stratified sampling" technique, which means that, the Fund
                   will select one or two individual bond issues to represent
                   entire "classes" or types of fixed-income investments in the
                   Index.
    
 
   
                   At the broadest level, the Fund will seek to hold securities
                   reflecting the three major classes of fixed-income
                   investments in the Lehman Brothers Index -- U.S. Treasury and
                   Government agency securities, corporate debt obligations, and
                   mortgage-backed securities. For example, if corporate debt
                   obligations represent 25% of the Index, then 25% of the
                   Fund's bond holdings will also be invested in such
                   securities. As the Fund's assets grow, these classes of
                   investments will be further delineated along the lines of
                   sector, term to maturity, coupon, and credit rating. For
                   example, within the corporate debt class, all long-term, low
                   coupon AA-rated utility bonds might be represented in the
                   Fund by one or two individual utility securities, which would
                   result in less diversification and greater security specific
                   risk in the Fund compared to the Index.

                   The Lehman Brothers Index is a trademark of Lehman Brothers,
                   Inc. Inclusion of a security in the Index in no way implies
                   an opinion by Lehman Brothers, Inc. as to the attractiveness
                   or appropriateness of a security as an investment. Lehman
                   Brothers, Inc. is neither a sponsor of nor in any way
                   affiliated with the Fund.
 
THE FUND'S RETURNS
SHOULD BE CLOSELY
CORRELATED WITH ITS
UNDERLYING INDEXES The sampling techniques utilized by the Fund are expected to
                   be an effective means of substantially duplicating the
                   investment performance (dividend income plus capital change)
                   of the Fund's underlying indexes: the Wilshire 5000 (for the
                   60% of net assets invested in common stocks) and the Lehman
                   Brothers Index (for the 40% of net assets invested in bonds).
                   The correlation between the performance of the Fund's stock
                   and bond investments and the Wilshire 5000 and Lehman
                   Brothers Indexes, respectively, is expected to be at least
                   0.95.
 
                   Due to the use of sampling techniques, however, neither the
                   stock nor bond holdings of the Fund are expected to track
                   their target benchmarks with the degree of accuracy that
                   complete replication of the indexes would have provided. The
                   principal advantage of this sampling approach is to provide
                   an efficient means of investing in a large universe of stocks
                   and bonds. In particular, the Fund is expected to provide
                   exceptionally broad diversification, and should operate at
                   low costs due to both its "passive" approach to portfolio
                   management and expected low portfolio turnover rate.

INDEX TRUST
THE 500 PORTFOLIO
INVESTS IN ALL 500 S&P
STOCKS             The 500 Portfolio attempts to duplicate the investment
                   results of the S&P 500 Index by holding all 500 stocks in
                   approximately the same proportions as they are represented in
                   the Index. This indexing technique is known as "complete
                   replication."
 
   
                   The S&P 500 Index is composed of 500 common stocks, which are
                   chosen by Standard & Poor's Corporation on a statistical
                   basis to be included in the Index. The inclusion of a stock
                   in the S&P 500 Index in no way implies that Standard & Poor's
                   Corporation believes the stock to be an attractive
                   investment. The 500 securities, most of which trade on the
                   New York Stock Exchange, represented, as of December 31,
                   1994, approximately 69% of the market value of all U.S.
                   common stocks. Each stock in the S&P 500 Index is weighted by
                   its market value.
    
 
   
                   Because of the market-value weighting, the 50 largest
                   companies in the S&P 500 Index currently account for
                   approximately 46% of the Index. Typically, companies included
                   in the S&P 500 Index are the largest and most dominant firms
                   in their respective industries. As of December 31, 1994, the
                   five largest companies in the Index were: General Electric
                   (2.6%), American Telephone and Telegraph (2.4%), Exxon
                   Corporation (2.3%), Coca-Cola (2.0%), and Royal Dutch
                   Petroleum (1.7%). The largest industry categories were:
                   telephone companies (8.5%), international oil companies
                   (6.3%), pharmaceutical companies (5.3%), banks (5.3%), and
                   electric power (4.0%).

MEDIUM- AND
SMALL-SIZE COMPANY
STOCKS             While the S&P 500 Index includes the preponderance of large
                   market capitalization stocks, it excludes most of the medium-
                   and small-size companies which comprise the remaining 31% of
                   the capitalization of the U.S. stock market. The Wilshire
                   4500 Index consists of all U.S. stocks that are not in the
                   S&P 500 Index and that trade regularly on the New York and
                   American Stock Exchanges as well as in the NASDAQ
                   over-the-counter market. More than 5,000 stocks of medium- 
                   and small-capitalization companies are included in the 
                   Wilshire 4500 Index.
    
 
                   The Extended Market Portfolio will be unable to hold all of
                   the more than 5,000 issues which comprise the Wilshire 4500
                   Index because of the costs involved and the illiquidity of
                   many of the securities. Instead, the Portfolio will hold a
                   representative sample of the securities in the Wilshire 4500
                   Index.

                   The Wilshire 5000 Index, which consists of all regularly and
                   publicly traded U.S. stocks, provides a complete proxy for
                   the U.S. stock market. More than 6,000 stocks, including
                   large-, medium-, and small-capitalization companies are
                   included in the Wilshire 5000 Index.
 
                   In an effort to replicate the investment performance of the
                   Wilshire 5000 Index, the Total Stock Market Portfolio will

                   in the case for the Extended Market Portfolio, the high
                   transaction costs and illiquidity of many of the smaller
                   stocks make complete replication of the Wilshire 4500 Index's

                   investing in approximately 1,000 of the 2,000 stocks in the
                   Russell 2000 Index. The Russell 2000 Index is composed of
                   approximately 2,000 small-capitalization common stocks. A
                   company's stock market capitalization is the total market
                   value of its floating outstanding shares. As of December 31,
                   1994, the average stock market capitalization of the Russell
                   2000 was $211 million. As in the case of the Extended Market
                   Portfolio, the high transaction costs and illiquidity of many
                   of the small stocks contained in the Russell 2000 Index make
                   complete replication of the holdings impractical.

                   correlation, which would be achieved when the net asset value
                   of a Portfolio, including the value of its dividend and
                   capital gains distributions, increases or decreases in exact
                   proportion to changes in the respective target benchmark.
 
                   Due to the use of the sampling technique, neither the
                   Extended Market Portfolio, Total Stock Market Portfolio nor
                   the Small Capitalization Stock Portfolio is expected to track
                   its benchmark index with the same degree of accuracy as
                   evidenced by the high degree of correlation between the 500
                   Portfolio and its benchmark. However, the principal advantage
                   of this technique is to provide an efficient means to invest
                   in the universe of stocks. In particular, the three
                   Portfolios are expected to provide broad diversification, and
                   should operate at low costs due both to their "passive"
                   approach to portfolio management and low portfolio turnover
                   rate.
 
THE VALUE AND GROWTH
PORTFOLIOS EMPHASIZE
STOCKS WITH CERTAIN
INVESTMENT
CHARACTERISTICS    In an effort to duplicate the investment results of their
                   respective indexes, the Value and Growth Portfolios will
                   utilize "complete replication," the same indexing technique
                   used for the 500 Portfolio. Specifically, the Value and
                   Growth Portfolios will hold all of the stocks included in the
                   S&P/BARRA Value and Growth Indexes, respectively, in
                   approximately the same proportions as those stocks are
                   represented in the Indexes.
 
   
                   Standard & Poor's Corporation constructs the S&P/BARRA Value
                   and Growth Indexes semi-annually by ranking all common stocks
                   included in the S&P 500 Index by their price-to-book ratios.
                   The resulting list is then divided in half by market
                   capitalization. Those companies representing half of the
                   market capitalization of the S&P 500 Index and having lower
                   price-to-book ratios are included in the S&P/BARRA Value
                   Index; the remaining companies are incorporated in the
                   S&P/BARRA Growth Index. On December 31, 1994, after the
                   semi-annual reconstitution of the indexes, the S&P/BARRA
                   Value Index consisted of 318 common stocks in the
    
 
                                       26
<PAGE>   85
 
   
                   S&P 500 Index, while the S&P/BARRA Growth Index consisted of
                   the remaining 182. Each Index represented half of the market
                   capitalization of the S&P 500 Index.
    
 
                   Investment managers may use a number of different methods to
                   classify stocks as "value" or "growth". There may also be
                   other ways to define benchmarks for "value" and "growth"
                   investing. If other methods were applied to the companies
                   comprising the S&P/BARRA Value and Growth Indexes, the
                   classification of the stocks as "growth" or "value" might be
                   different.
 
   
                   Typically, the stocks included in the S&P/BARRA Value Index
                   exhibit above-average dividend yields and lower price-to-book
                   ratios. By comparison, the stocks included in the S&P/BARRA
                   Growth Index exhibit below-average dividend yields and higher
                   price-to-book ratios. As of December 31, 1994, the five
                   largest companies in the S&P/BARRA Value Index were Exxon
                   Corp., Royal Dutch Petroleum Co., IBM, DuPont E.I. de Nemour,
                   and Mobil, the five largest companies in the S&P/BARRA Growth
                   Index were General Electric Co., American Telephone &
                   Telegraph, Coca Cola Co., Phillip Morris Cos., Inc., and
                   Wal-Mart Stores.

SAMPLING TECHNIQUES
("PORTFOLIO
OPTIMIZATION")     The MCSI-Europe (Free) Index consists of approximately 590
                   equity securities from Europe, and the MSCI-Pacific (Free)
                   Index consists of more than 520 equity securities from
                   Australia and the Far East. The stocks included in each index
                   are chosen by Morgan Stanley Capital International on a
                   statistical basis. Each stock in MSCI-Europe (Free) and
                   MSCI-Pacific (Free) is weighted according to its market value
                   as a percentage of the total market value of all stocks in
                   the index. (A stock's market value equals the number of
                   shares outstanding times the most recent price of the
                   security.) The inclusion of a stock in the index in no way
                   implies the Morgan Stanley Capital International believes the
                   stock to be an attractive investment.
    
 
                   The Portfolios will be unable to hold all of the issues that
                   comprise their respective indexes because of the costs
                   involved and the illiquidity of many of the securities.
                   Instead, each Portfolio will attempt to hold a representative
                   sample of approximately 250 or more of the securities in its
                   respective Index, which will be selected utilizing the
                   statistical technique, "portfolio optimization." (See page 23
                   for a general explanation of "portfolio optimization".)
 
                   Due to the use of this sampling or "portfolio optimization"
                   technique, the Portfolios are not expected to track their
                   benchmark indexes with the same degree of accuracy as large
                   capitalization domestic index funds. Over time, the
                   correlation between the performance of each Portfolio and its
                   respective index is expected to be greater than 0.95. A
                   correlation of 1.00 would indicate perfect correlation, which
                   would be achieved when the net asset value of each Portfolio,

THE PORTFOLIO INVESTS
IN INTERNATIONAL
COMMON STOCKS USING
SAMPLING TECHNIQUES
("PORTFOLIO
OPTIMIZATION")     The MSCI -- Select Emerging Markets Free Index consists of
                   approximately 490 equity securities from emerging market
                   countries in Europe, Latin America and Southeast Asia. The
                   stocks included in the Index are chosen on a statistical
                   basis. The companies based in Hong Kong and Singapore are
                   included in the Index to provide participation in more liquid
                   emerging markets; their combined weight is limited to 20% of
                   the Index. Each stock within Hong Kong and Singapore will be
                   weighted according to its market value as a percentage of the
                   total market value of all of the Hong Kong and Singapore
                   stocks included in the index. (A stock's market value equals
                   the number of shares outstanding times the most recent price
                   of the security). The remaining portion of the Index will be
                   comprised of common stocks from 10 other emerging market
                   countries -- Indonesia, Malaysia, the Philippines, Thailand,
                   Argentina, Brazil, Mexico, Greece, Portugal and Turkey. Each
                   stock in these countries will be weighted according to its
                   market value as a percentage of the total market value of the
                   companies in the 10 countries multiplied by the percentage of
                   the index that these countries represent. From time to time,
                   additional emerging markets will be analyzed for inclusion in
                   the Index, based on liquidity and tradeability. The inclusion
                   of a country or stock in the Index in no way implies that the
                   country or stock is an attractive investment.
    
 
                   The Portfolio will be unable to hold all of the issues that
                   comprise its Index, because of the transaction costs involved
                   and the illiquidity of many of the securities. Instead, the
                   Portfolio will attempt to hold a representative sample of
                   approximately 300 or more of the securities in its Index by
                   selecting stocks utilizing the statistical technique,
                   "portfolio optimization." (See page 23 for a general
                   explanation of "portfolio optimization".)
 
                   Due to the use of this sampling or "portfolio optimization"
                   technique, the Portfolio is not expected to track its
                   benchmark with the same degree of accuracy as large
                   capitalization domestic index funds. Over time, the
                   correlation between the performance of the Portfolio and the
                   Index is expected to be greater than 0.95. A correlation of
                   0.95 or higher is expected to be achieved when the Portfolio
                   exceeds $100 million in assets.
 
THE THREE PORTFOLIOS
MAY ENTER INTO
FORWARD CURRENCY
CONTRACTS          Each Portfolio may enter into foreign currency forward and
                   foreign currency futures contracts in order to maintain the
                   same currency exposure as their respective indexes. A
                   Portfolio may not enter into such contracts for speculative
                   purposes, or as a way of protecting against anticipated
                   adverse changes in exchange rates between foreign currencies
                   and the U.S. dollar. Specifically, a Portfolio may invest up
                   to 25% of its assets in foreign currency forward contracts. A
                   foreign currency forward 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 THREE PORTFOLIOS
MAY BORROW MONEY   Each Portfolio may borrow money from a bank up to a limit of
                   15% of the market value of its assets, but only for temporary
                   or emergency purposes. A Portfolio may borrow money only to
                   meet redemption requests prior to the settlement of
                   securities already sold or in the process of being sold by
                   the Portfolio. To the extent that a Portfolio borrows money
                   prior to selling securities, the Portfolio may be leveraged;
                   at such times, the Portfolio may appreciate or depreciate in
                   value more rapidly than its benchmark index. Both Portfolios
                   will repay any money borrowed in excess of 5% of the market
                   value of their total assets prior to purchasing additional
                   portfolio securities.

ALL PORTFOLIOS MAY
INVEST IN SHORT-TERM
MONEY MARKET
INSTRUMENTS        Although they normally seek to remain substantially fully
                   invested in securities in the respective indexes, all
                   Portfolios of the Funds may invest temporarily in certain
                   short-term money market instruments. Such securities may be
                   used to invest uncommitted cash balances or to maintain
                   liquidity to meet shareholder redemptions. 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 Funds may use futures contracts, options, warrants,
                   convertible securities and swap agreements.
 
BOND INDEX FUND    The Portfolios of the Fund may utilize bond (interest rate)
                   futures contracts and options to a limited extent.
                   Specifically, each Portfolio may enter into futures contracts
                   provided that not more than 5% of its assets are required as
                   a futures contract deposit. In addition, the Portfolios 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 a Portfolio's
                   assets.
- --------------------------------------------------------------------------------
 
BALANCED INDEX
FUND               The Fund may utilize stock and bond (interest rate) futures
                   contracts, options, warrants, convertible securities and swap
                   agreements to a limited extent. Specifically, the Fund may
                   enter into futures contracts and options provided that not
                   more than 5% of its assets are required as a margin deposit
                   for futures contracts or options. Additionally, the Fund's
                   investment in warrants will not exceed more than 5% of its
                   assets (2% with respect to warrants not listed on the New
                   York or American Stock Exchanges). The Fund does not intend
                   to invest more than 5% of its assets in convertible
                   securities.
- --------------------------------------------------------------------------------
 
INDEX TRUST        Each Portfolio of the Trust may utilize stock futures
                   contracts, options, warrants, convertible securities and swap
                   agreements to a limited extent. Specifically, each Portfolio
                   may enter into futures contracts and options provided that
                   not more than 5% of its assets are required as a margin
                   deposit for futures contracts or options and provided that
                   not more than 20% of a Portfolio's assets are invested in
                   futures and options at any time. Additionally, the Trust's
                   investment in warrants will not exceed more than 5% of its
                   assets (2% with respect to warrants not listed on the New
                   York or American Stock Exchanges). The Trust does not intend
                   to invest more than 5% of its assets in convertible
                   securities.
- --------------------------------------------------------------------------------
 
INTERNATIONAL
EQUITY INDEX FUND  The Portfolios of the Fund may utilize stock futures
                   contracts, options, warrants, convertible securities and swap
                   agreements to a limited extent. Specifically, each Portfolio
                   may enter into futures contracts and options provided that
                   not more than 5% of its assets are required as a margin
                   deposit for futures contracts or options. Additionally, the
                   Fund's investment in warrants will not exceed more than 5% of
                   its assets (for the European Portfolio and the Pacific
                   Portfolio 2% with respect to warrants not listed on the New
                   York or American Stock Exchanges).
 
                   Futures contracts, options, warrants, convertible securities
                   and swap agreements may be used for several reasons: to
                   simulate full investment in the underlying index while
                   retaining a cash balance for fund management purposes, to
                   facilitate trading, to reduce transaction costs or to seek
                   higher investment returns when a futures contract, option,
                   warrant, convertible security or swap agreement is priced
                   more attractively than the underlying equity security or
                   index. While each of these securities can be used as
                   leveraged investments, the Portfolios may not use them to
                   leverage their net assets.
 
FUTURES CONTRACTS,
OPTIONS, WARRANTS,
CONVERTIBLE SECURITIES
AND SWAP AGREEMENTS
POSE CERTAIN RISKS The risk of loss associated with 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 an
                   immediate and substantial loss or gain. When investing in
                   futures contracts, Portfolios of the Vanguard Bond Index Fund
                   will segregate cash or cash equivalents in the amount of the
                   underlying obligation. The Portfolios of the Vanguard
                   Balanced Index Fund, Vanguard Index Trust and Vanguard
                   International Equity Index Fund will not use futures
                   contracts, options, warrants, convertible securities or swap
                   agreements for speculative purposes or to leverage its net
                   assets. Accordingly, the primary risks associated with the
                   use of futures contracts, options,
 
                                       29

                   warrants, convertible securities or swap agreements by the
                   Portfolio are: (i) imperfect correlation between the change
                   in market value of the stocks held by the Portfolio and the
                   prices of futures contracts, options, warrants, convertible
                   securities or swap agreements; (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; and (iii) the risk of the counterparty or guaranteeing
                   agent defaulting. 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 an exchange with an active and
                   liquid secondary market. However, options, warrants,
                   convertible securities or swap agreements purchased or sold
                   over-the-counter may be less liquid than exchange-traded
                   securities. Illiquid securities, in general, including swap
                   agreements, may not represent more than 15% of the net assets
                   of the Portfolio.
    
 
                   Since there are no futures traded on the S&P/BARRA Value and
                   Growth Indexes, MSCI-Europe (Free), Pacific Index or the
                   MSCI-Select Emerging Markets Free Index, it will be necessary
                   for the Vanguard Index Trust Value and Growth Portfolios and
                   the Portfolios of Vanguard International Equity Index Fund to
                   utilize a composite of other futures contracts to simulate
                   the performance of the Indexes. This process may magnify the
                   "tracking error" of a Portfolio's performance compared to
                   that of its Index, due to lower correlation of the selected
                   futures with its Index. The investment adviser will attempt
                   to reduce this tracking error by investing in futures
                   contracts whose behavior is expected to resemble that of the
                   underlying securities, although there can be no assurance
                   that these selected futures will perfectly correlate with the
                   performance of either Index.
 
   
SWAP AGREEMENTS    Swap agreements are contracts between parties in which one
                   party agrees to make payments to the other party based on the
                   change in market value of a specified index or asset. In
                   return, the other party agrees to make payments to the first
                   party based on the return of a different specified index or
                   asset. Although swap agreements entail the risk that a party
                   will default on its payment obligations thereunder, the
                   Portfolios will minimize this risk by entering into
                   agreements that mark to market no less frequently than
                   quarterly. However, the Portfolios' daily share price will
                   take into effect the daily price movement of any swap
                   agreement entered into by the Portfolios. Swap agreements
                   also bear the risk that the Portfolios will not be able to
                   meet its obligation to the counterparty. This risk will be
                   mitigated by investing the Portfolios in the specific asset
                   for which it is obligated to pay a return.
    
 
ALL PORTFOLIOS MAY
LEND THEIR SECURITIES
                   All Portfolios may lend their investment securities to
                   qualified institutional investors for either short-term or
                   long-term purposes of realizing additional 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. The collateral will equal at
                   least 100% of the current market value of the loaned
                   securities.
 
PORTFOLIO TURNOVER FOR
ALL PORTFOLIOS IS
EXPECTED TO BE LOW Although they generally seek to invest for the long term,
                   each Portfolio of Vanguard Bond Index Fund, Vanguard Balanced
                   Index Fund, Vanguard Index Trust, and Vanguard International
                   Equity Index Fund retains the right to sell securities
                   irrespective of how long they have been held. It is
                   anticipated that the annual portfolio turnover of each
                   Portfolio of the Funds (except Vanguard Balanced Index Fund)
                   will not exceed 50%. The annual portfolio turnover rate for
                   the Vanguard Balanced Index Fund is not expected to exceed
                   100%. A turnover rate of 50% would occur, for example, if one
                   half of the securities of a Portfolio were replaced within
                   one year.

INVESTMENT
LIMITATIONS
EACH PORTFOLIO HAS
ADOPTED CERTAIN
FUNDAMENTAL
LIMITATIONS        Each portfolio of the Funds has adopted certain limitations
                   on its investment practices. Specifically, each Portfolio
                   will not:
 
                   (a)  invest more than 25% of its assets in any one industry;
 
                   (b)  borrow money, except that the Funds may borrow from
                        banks (or through reverse repurchase agreements), for
                        temporary or emergency (not leveraging) purposes,
                        including the meeting of redemption requests which
                        might otherwise require the untimely disposition of
                        securities, in an amount not exceeding 15% of the value
                        of the Funds' net assets. Whenever borrowing exceeds 5%
                        of the value of the Funds' net assets, the Funds will
                        not make any additional investments.
 
                   Each Portfolio of Vanguard Bond Index will not:
 
                   (a)  invest more than 5% of its assets in the securities of
                        any single issuer except obligations of the United
                        States Government;
 
                   (b)  purchase more than 5% of the voting securities of any
                        issuer;
 
                   (c) pledge, mortgage or hypothecate its assets to an extent
                       greater than 5% of the value of its total assets.
 
                   Each Portfolio of Vanguard Balanced Index Fund, Vanguard
                   Index Trust, and Vanguard International Equity Index Fund
                   will not:
 
                   (a)  with respect to 75% of its assets, purchase securities
                        of any issuer (except obligations of the U.S. Government
                        and its instrumentalities) if, as a result, more than 5%
                        of the value of the Fund's assets would be invested in
                        the securities of each issuer; and
 
                   (b)  with respect to 75% of its assets, purchase more than
                        10% of the voting securities of any issuer.
 
                   These investment limitations are considered at the time
                   investment securities are purchased. The limitations
                   described here and in the Statement of Additional Information
                   may be changed for a specific Fund only with the approval of
                   a majority of the shareholders.

MANAGEMENT OF
THE FUNDS
VANGUARD ADMINISTERS
AND DISTRIBUTES
THE FUNDS          The Funds are members of The Vanguard Group of Investment
                   Companies, a family of more than 30 investment companies with
                   more than 80 distinct portfolios and total assets in excess
                   of $130 billion. Through their jointly owned subsidiary, The
                   Vanguard Group, Inc. ("Vanguard"), they and the other funds
                   in the Group obtain at cost virtually all of their corporate
                   management, administrative, shareholder accounting 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 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 Funds manage its day to day operations
                   and are responsible to the Funds Board of Directors
                   (Trustees). The Directors (Trustees) set broad policies for
                   the Funds and choose its officers. A list of the Directors
                   (Trustees) and Officers of the Funds and a statement of their
                   present positions and principal occupations during the past
                   five years can be found in each of the Funds Statements of
                   Additional Information.
 
                   Vanguard employs a supporting staff of management and
                   administrative personnel needed to provide the requisite
                   services to the funds and also furnishes the funds with
                   necessary office space, furnishings and equipment. Each fund
                   pays its share of Vanguard's net expenses, which are
                   allocated among the funds under methods approved by the Board
                   of Directors (Trustees) of each fund. In addition, each fund
                   bears its own direct expenses, such as legal, auditing and
                   custodian fees.

                   Vanguard also provides distribution and marketing services to
                   the Vanguard 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 it share of the Group's distribution
                   costs.

ADVISERS
VANGUARD'S FIXED
INCOME GROUP
MANAGES SOME OF THE
FUNDS' INVESTMENTS Each Portfolio of Vanguard Bond Index Fund and the bond
                   portion of Vanguard Balanced Index Fund receive all
                   investment advisory services from Vanguard's Fixed Income
                   Group. The Fixed Income Group provides investment advisory
                   services to more than 40 Vanguard money market and bond
                   portfolios, both taxable and tax-exempt. Total assets under
                   management by Vanguard's Fixed Income Group were $55 billion
                   as of December 31, 1994. The Portfolios are not actively
                   managed, but are instead administered by the Fixed Income
                   Group using computerized, quantitative techniques. The Fixed
                   Income Group is supervised by the Officers of the Fund. Ian
                   A. MacKinnon, Senior Vice President of Vanguard, has been in
                   charge of the Group since its inception in 1981.
    
 
                   Mr. MacKinnon is responsible for setting the broad investment
                   strategies employed by the Fund, and for overseeing the
                   portfolio manager who implements those strategies on a
                   day-to-day basis.
 
                   The portfolio manager for Vanguard Bond Index Fund and the
                   bond portion of Vanguard Balanced Index Fund is Kenneth E.
                   Volpert, Assistant Vice President of Vanguard, who serves as
                   portfolio manager of the Vanguard Variable Insurance
                   Fund -- High-Grade Portfolio and the bond portion of the
                   Balanced Portfolio. Mr. Volpert began managing the Vanguard
                   Bond Index fund in 1992. For six years prior to joining
                   Vanguard, Mr. Volpert was associated with Mellon Bond
                   Associates.
 
                   The Fixed Income Group places all orders for purchases and
                   sales of portfolio securities. Purchases of portfolio
                   securities are made either directly from the issuer or from
                   securities dealers. The Fixed Income Group may sell portfolio
                   securities prior to their maturity if circumstances and
                   considerations warrant and if it believes such dispositions
                   advisable. The Group seeks to obtain the best available net
                   price and most favorable execution for all portfolio
                   transactions.
 
   
VANGUARD'S CORE
MANAGEMENT GROUP
MANAGES SOME OF THE
FUNDS, ON AN AT-COST
BASIS              Each Portfolio of Index Trust, International Equity Index
                   Fund and the equity portion of Balanced Index Fund receive
                   their investment advisory services on an at-cost basis from
                   Vanguard's Core Management Group, which also provides
                   investment advisory services to Vanguard Institutional Index
                   Fund, a portion of the assets of Vanguard/Windsor II and
                   Vanguard Morgan Growth Fund, the Equity Index Portfolio of
                   Vanguard Variable Insurance Fund, Vanguard Tax-Managed Fund,
                   and several indexed separate accounts. Total indexed assets
                   under management as of December 31, 1994 were $18 billion.
                   The Portfolios of the Fund are not actively managed, but are
                   instead administered by the Core Management Group using
                   computerized, quantitative techniques. The Group is
                   supervised by the Officers of the Fund.
    
 
                   In placing portfolio transactions, Vanguard's Core Management
                   Group uses its best judgment to choose the broker most
                   capable of providing the brokerage services necessary to
                   obtain the best available price and most favorable execution
                   at the lowest commission rate. The full range and quality of
                   brokerage services available are considered in making these
                   determinations. In those instances where it is reasonably
                   determined that more than one broker can offer the services
                   needed to obtain the best available price and most favorable
                   execution, consideration may be given to those brokers which
                   supply statistical information and provide other services in
                   addition to execution services to the Fund.

                   The Balanced Index Fund will distribute substantially all of
                   its net investment income in the form of quarterly dividends.
 
                   Dividends consisting of virtually all of the ordinary income
                   of each Portfolio of Bond Index Fund are declared daily and
                   are payable to shareholders of record at the time of
                   declaration. Such dividends are paid on the first business
                   day of each month. Capital gains distributions, if any, are
                   made annually.
 
                   A Portfolio's dividend and capital gains distributions may be
                   reinvested in additional shares or received in cash. See
                   "Choosing a Distribution Option" for a description of these
                   distribution methods. Shareholders of Bond Index Fund who
                   choose to reinvest their dividend distributions will receive
                   a quarterly (not monthly) confirmation statement.
 
   
                   Pursuant to the Internal Revenue Code, certain dividend and
                   capital gains distributions declared by each Portfolio during
                   December, if received by shareholders by January 31, are
                   deemed to have been paid by the Funds and received by
                   shareholders on December 31 of the prior year.
    
 
                   Each Portfolio of the Funds intends to continue to qualify
                   for taxation as a "regulated investment company" under the
                   Internal Revenue Code so that each Portfolio will not be
                   subject to federal income tax to the extent its income is
                   distributed to shareholders. Dividends paid by each 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
                   a Portfolio from domestic (U.S.) sources.
 
   
                   Distributions paid by a Portfolio from long-term capital
                   gains, whether received in cash or reinvested in additional
                   shares, are taxable as long-term capital gains, regardless of
                   the length of time you have owned shares in the Portfolio.
                   Capital gains distributions are made when a Portfolio
                   realizes net capital gains on sales of portfolio securities
                   during the year. A 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 a 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 a
                   Portfolio. Also, keep in mind that if you purchase shares in
                   a 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 Funds will notify you annually as to the tax status of
                   dividend and capital gains distributions paid by each
                   Portfolio.
 
   
EACH PORTFOLIO OF
INTERNATIONAL EQUITY
INDEX FUND MAY
"PASS THROUGH"
FOREIGN TAXES      Each Portfolio may elect to "pass through" to its
                   shareholders the amount of foreign income taxes paid by a
                   Portfolio. The Portfolios will make such an election only if
                   it is deemed to be in the best interests of the shareholders.
                   If this election is made, shareholders of a 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 (but not both) on their
                   federal income tax return.
    
 
A CAPITAL GAIN OR LOSS
MAY BE REALIZED UPON
EXCHANGE OR
REDEMPTION         A sale of shares of a 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 the same fund).
 
                   Dividend distributions, capital gain distributions, and
                   capital gains or losses from redemptions and exchanges may be
                   subject to state and local taxes.

                   Each Portfolio of the Funds 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 by certifying that you are not
                   subject to backup withholding.
    
 
                   Vanguard Index Trust is organized as a Pennsylvania business
                   trust and, in the opinion of counsel, is not liable for any
                   income or franchise tax in the Commonwealth of Pennsylvania.
                   The Trust will be subject to Pennsylvania county personal
                   property tax in the county which is the site of its principal
                   office. Shareholders who are Pennsylvania residents will not
                   be subject to county personal property taxes, with the
                   exception of non-exempt holders who are residents of the City
                   and School District of Pittsburgh.
 
                   The International Equity Index, Balanced Index and Bond Index
                   Funds have obtained Certificates of Authority to do business
                   as foreign corporations in Pennsylvania and do business and
                   maintain offices in that state. In the opinion of counsel,
                   the shares of each of the Funds 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 Funds.

THE SHARE
PRICE OF
EACH PORTFOLIO     The share price or "net asset value" per share of each
                   Portfolio is determined by dividing the total market value of
                   the Portfolio's investments and other assets, less any
                   liabilities, by the number of outstanding shares of the
                   Portfolio. Net asset value per share is determined once daily
                   at the close of regular trading on the New York Stock
                   Exchange (generally 4:00 p.m. Eastern time).
 
   
                   Portfolio securities that are listed on a securities exchange
                   are valued at the last quoted sales price on the day the
                   valuation is made. Price information on listed securities is
                   taken from the exchange where the security is primarily
                   traded. Securities which are listed on an exchange and which
                   are not traded on the valuation date are valued at the mean
                   of the bid and ask prices. For the 500, Value and Growth
                   Portfolios of Vanguard Index Trust, Vanguard International
                   Equity Index Fund, and each Portfolio of Vanguard Bond Index
                   Fund, unlisted securities for which market quotations are
                   readily available are valued at the latest quoted bid price.
                   For the Extended Market, Total Stock Market and Small
                   Capitalization Stock Portfolios, and Vanguard Balanced Index
                   Fund, unlisted securities for which market quotations are not
                   readily available are valued at the mean of the bid and ask
                   prices. Temporary cash investments are valued at amortized
                   cost which approximates market value. For all Funds,
                   securities for which no current quotations are readily
                   available are valued at fair market value as determined in
                   good faith by the Directors (Trustees). 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.
    
 
                   Each Portfolios's share price can be found daily in the
                   mutual fund listings of most major newspapers under the
                   heading of The Vanguard Group.

                   corporations. The Articles of Incorporation permit the
                   Directors to issue 1,000,000,000 shares of common stock of
                   each Fund, with a $.001 par value. The Board of Directors has
                   the power to designate one or more classes ("series") of
                   shares of common stock and to classify or reclassify any
                   unissued shares with respect to such series. Currently,
                   Vanguard Bond Index Fund is offering shares of four series,
                   Vanguard Balanced Index Fund is offering shares of one series
                   and Vanguard International Equity Index is offering shares of

                   unlimited number of shares of beneficial interest with no par
                   value. The Board of Trustees has the power to designate one
                   or more classes or series of shares of common stock and to
                   classify or reclassify any unissued shares with respect to
                   such series. Currently, the Trust is offering shares of six
                   series.

                   exchange, dividends, retirement or other features; and have
                   no preemptive rights. Such shares have non-cumulative voting
                   rights, meaning that the holders of more than 50% of the
                   shares voting for the election of Directors (Trustees) can
                   elect 100% of the Directors (Trustees) if they so choose.

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 Portfolio you have chosen and amount you wish
                   to invest. Your purchase must be equal to or greater than the
                   $3,000 minimum initial investment requirement in any
                   Portfolio ($500 for Uniform Gifts/Transfers to Minors Act
                   accounts). You must open a new Individual Retirement Account
                   by mail (IRAs may not be opened by wire) using a Vanguard IRA
                   Adoption Agreement. Your purchase must be equal to or greater
                   than the $500 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 Account Registration Form or have any questions about the
                   Fund, please call our Investor Information Department
                   (1-800-662-7447). NOTE: For other types of account
                   registrations (e.g., corporations, associations, other
                   organizations, trusts or powers of attorney), please call us
                   to determine which additional forms you may need.
    
 
                   Because of the risks associated with bond and stock
                   investments, each 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 bond market
                   movements. Consequently, the Fund reserves the right to
                   reject any specific purchase (and exchange purchase) request.
                   The Fund also reserves the right to suspend the offering of
                   shares for a period of time.
 
                   Each Portfolio's shares are purchased at the next-determined
                   net asset value after your investment has been received in
                   the form of Federal Funds. See "When Your Account Will Be
                   Credited". The Fund is offered on a no-load basis (i.e.,
                   there are no sales commissions or 12b-1 fees).

TAX CAUTION
INVESTORS SHOULD ASK
ABOUT THE TIMING OF
CAPITAL GAINS AND
DIVIDEND DISTRIBUTIONS
BEFORE INVESTING   Under Federal tax laws, the Fund is required to distribute
                   net capital gains and dividend income to Fund shareholders.
                   These distributions are made to all shareholders who own Fund
                   shares as of the distribution's record date, regardless of
                   how long the shares have been owned. Purchasing shares just
                   prior to the record date could have a significant impact on
                   your tax liability for the year. For example, if you purchase
                   shares immediately prior to the record date of a sizable
                   capital gain distribution, you will be assessed taxes on the
                   amount of the capital gain distribution later paid even
                   though you owned the Fund shares for just a short period of
                   time. (Taxes are due on the distributions even if the
                   dividend or gain is reinvested in additional Fund shares.)
                   While the total value of your investment will be the same
                   after the capital gain distribution -- the amount of the
                   capital gain 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. Each Fund's annual
                   capital gains distributions normally occurs in December.
                   Income dividends are generally paid on the first day of each
                   month for the four Portfolios of Vanguard Bond Index Fund,
                   annually in December for the three Portfolios of Vanguard
                   International Equity Index Fund, and the Extended Market and
                   Small Capitalization Stock Portfolio of Vanguard Index Trust,
                   and quarterly in March, June, September and December for
                   Vanguard Balanced Index Fund, and the 500, Total Stock
                   Market, and the Value and Growth Portfolios of Vanguard Index
                   Trust. For additional information on distributions and taxes,
                   see the section titled "Dividends, Capital Gains, and Taxes."

WHEN YOUR
ACCOUNT WILL
BE CREDITED        The trade date is the date on which your account is credited.
 
                   For the Vanguard Bond Index Fund, the trade date is generally
                   the day on which the Fund receives your investment in the
                   form of Federal Funds (monies credited to the Fund's
                   Custodian Bank by a Federal Reserve Bank). Your trade date
                   varies according to your method of payment for your shares.
 
   
                   Purchases of Fund shares by check will receive a trade date
                   the day the funds are received in good order by Vanguard.
                   Thus, if your purchase by check 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 business day
                   your check is received in good order. If your purchase is
                   received after the close of the Exchange your trade date is
                   the business day following receipt of your check. Vanguard
                   will not accept third-party checks to open an account. Please
                   be sure your purchase check is made payable to the Vanguard
                   Group.
    
 
                   For purchases by Federal Funds wire or exchange, the Fund is
                   credited immediately with Federal Funds. Thus, if your
                   purchase by Federal Funds wire or exchange is received by the
                   close of the Exchange, your trade date is the day of receipt.
                   If your purchase is received after the close of the Exchange,
                   your trade date is the business day following receipt of your
                   wire or exchange.
 
                   For Vanguard Balanced Fund, Vanguard Index Trust and Vanguard
                   International Equity Index Fund, if your purchase is made by
                   check, Federal Funds wire or exchange, and is received by the
                   close of regular trading 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.
                   Shares of the Funds are purchased at the net asset value
                   determined on your trade date. Shares of the Extended Market
                   and Small Capitalization Stock Portfolios are also subject to
                   a 1% portfolio transaction fee, shares of the Total Stock
                   Market Portfolio are subject to a 0.25% portfolio transaction
                   fee. Shares of Vanguard International Equity Index
                   Fund-Pacific Portfolio and European Portfolio are subject to
                   a 1% transaction fee while shares of the Emerging Markets
                   Portfolio are subject to a 2% transaction fee on purchases.
                   See "Fund Expenses" for additional information.
 
                   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.
 
                   Your shares are purchased at the next-determined net asset
                   value after your investment has been received in the form of
                   Federal Funds. You will begin to earn dividends on the
                   calendar day following the trade date. (For a Friday trade
                   date, you will begin earning dividends on Saturday.)

SELLING YOUR
SHARES             You may withdraw any portion of the funds in your account by
                   redeeming shares at any time. You may initiate a request by
                   writing or by telephoning. Your redemption proceeds are
                   normally mailed, credited or wired -- depending upon the
                   method of withdrawal you have PREVIOUSLY chosen -- within two
                   business days after the receipt of the request in Good Order.

SELLING BY WRITING
A CHECK            Redemption by check is only available to shareholders of
                   Vanguard Bond Index Fund. You may withdraw funds from your
                   Vanguard Bond Index account by writing a check payable in the
                   amount of $250 or more. When a check is presented for payment
                   to the Fund's agent, CoreStates Bank, the Fund will redeem
                   sufficient shares in your account at the next-determined net
                   asset value to cover the amount of the check.
 
                   In order to establish the checkwriting option on your
                   account, all registered shareholders must sign a signature
                   card. After your completed signature card is received by the
                   Fund, an initial supply of checks will be mailed within 10
                   business days. There is no charge for checks or for their
                   clearance. CORPORATIONS, TRUSTS AND OTHER ORGANIZATIONS
                   SHOULD CALL OR WRITE OUR CLIENT SERVICES DEPARTMENT
                   (1-800-662-2739) BEFORE SUBMITTING SIGNATURE CARDS, AS
                   ADDITIONAL DOCUMENTS MAY BE REQUIRED TO ESTABLISH THE
                   CHECKWRITING SERVICE.
 
                   Before establishing the checkwriting option, you should be
                   aware that:
 
                   1. Writing a check (a redemption of shares) is a taxable
                      event.
                   2. The Fund does not allow an account to be closed through
                      the checkwriting option.
   
                   3. Vanguard cannot guarantee a stop payment on any check. If
                      you wish to reverse a stop payment order, you must do so
                      in writing.
    
                   4. Shares held in certificate form cannot be redeemed using
                      the checkwriting option.
                   5. The Fund reserves the right to terminate or alter this
                      service at any time.

                   representative may call our Client Services Department at
                   1-800-662-2739. For telephone redemptions, you may have the

                   BY MAIL: Telephone mail redemption is automatically
                   established on your account unless you indicate otherwise on
                   your Account Registration Form. You may redeem any amount by
                   calling Vanguard. The proceeds will be paid to the
                   registered shareholders and mailed to the address of record.

                   BY WIRE: Telephone wire redemption must be specifically
                   elected for your account. The best time to elect telephone
                   wire redemption is at the time you complete your Account
                   Registration Form. If you do not presently have telephone
                   wire redemption and wish to establish it, please contact
                   Client Services.
 
                   With the wire redemption option, you may withdraw a minimum
                   of $1,000 and have the amount wired directly to your bank
                   account. Wire redemptions less than $5,000 are subject to a
                   $5 charge deducted by Vanguard. There is no Vanguard charge
                   for wire redemptions of $5,000 or more. However, your bank
                   may assess a separate fee to accept incoming wires.
 
                   A request to change the bank associated with your wire
                   redemption option must be received in writing, signed by each
                   registered shareholder, and accompanied by a voided check or
                   preprinted deposit slip. A signature guarantee is required if
                   your bank registration is not identical to your Vanguard Fund
                   account registration.

                   account to your bank account according to the schedule you
                   have selected. The Special Redemption option (only available
                   to Vanguard Bond Index Fund Shareholders) lets you move money
                   from your Vanguard account to your bank account on an "as
                   needed" basis. To establish these Fund Express options,

SELLING BY
EXCHANGE           You may sell shares of the Portfolio by making an exchange
                   into another Vanguard Fund account. Exchanges to and from
                   Vanguard Balanced Fund, Vanguard Index Trust and Vanguard
                   International Equity Index Fund may be made only by mail.
                   Send your exchange request to Vanguard Financial Center,
                   Vanguard (insert Fund name), P.O. Box 1120, Valley Forge, PA
                   19482. Please see "Exchanging Your Shares" for details.
- --------------------------------------------------------------------------------
 
IMPORTANT REDEMPTION
INFORMATION        Shares purchased by check or Fund Express may be redeemed at
                   any time. However, your redemption proceeds will not be paid
                   until payment for the purchase is collected, which may take
                   up to ten calendar days.
- --------------------------------------------------------------------------------
 
DELIVERY OF
REDEMPTION
PROCEEDS           Redemption requests received by telephone prior to the close
                   of the New York Stock Exchange (generally 4:00 p.m. Eastern
                   time), are processed on the day of receipt and the redemption
                   proceeds are normally sent on the following business day.
 
                   Redemption requests received by telephone after the close of
                   the Exchange are processed on the business day following
                   receipt and the proceeds are normally sent on the second
                   business day following receipt.
 
                   Redemption proceeds must be sent to you within seven days of
                   receipt of your request in Good Order.
 
                   If you experience difficulty in making a telephone redemption
                   during periods of drastic economic or market changes, your
                   redemption request may be made by regular or express mail. It
                   will be implemented at the net asset value next determined
                   after your request has been received by Vanguard in Good
                   Order. The Fund reserves the right to revise or terminate the
                   telephone redemption privilege at any time.
 
                   The Fund may suspend the redemption right or postpone payment
                   at times when the New York Stock Exchange is closed or under
                   any emergency circumstances as determined by the United
                   States Securities and Exchange Commission.
 
                   If the Board of Directors determines that it would be
                   detrimental to the best interests of the Fund's remaining
                   shareholders to make payment in cash, the Fund may pay
                   redemption proceeds in whole or in part by a distribution in
                   kind of readily marketable securities.

VANGUARD'S AVERAGE
COST STATEMENT     If you make a redemption from a qualifying account, Vanguard
                   will send you an Average Cost Statement which provides you
                   with the tax basis of the shares you redeemed. Please see
                   "Other Vanguard Services" for additional information.
- --------------------------------------------------------------------------------
 
   
MINIMUM ACCOUNT
BALANCE 
REQUIREMENT        Due to the relatively high cost of maintaining smaller
                   accounts, the Fund reserves the right to redeem shares in any
                   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 your
                   account is below the Fund's minimum account balance
                   requirement. You would then be allowed 60 days to make an
                   additional investment before the account is liquidated.
                   Proceeds would be promptly paid to the registered
                   shareholder. (This minimum requirement does not apply to
                   IRAs, other retirement accounts, and Uniform Gifts/Transfers
                   to Minors Act accounts.)
    
 
   
                   The Fund's minimum account balance requirement will not apply
                   if your account falls below $3,000 solely as a result of
                   declining markets (i.e., a decline in a Portfolio's net asset
                   value).

                   Vanguard Bond Index Fund is the only Vanguard Index Fund that
                   allows telephone exchange. When exchanging shares by
                   telephone, please have ready the Portfolio name, account
                   number, Social Security Number or Employer Identification
                   number listed on the account, and exact name and address in
                   which the account is registered. Only the registered
                   shareholder may complete such an exchange. Requests for
                   telephone exchanges received prior to the close of the New
                   York Stock Exchange (generally 4:00 p.m. Eastern time) are
                   processed at the close of business that same day. Requests
                   received after the close of the Exchange are processed the
                   next business day. TELEPHONE EXCHANGES ARE NOT ACCEPTED INTO

                   VANGUARD INTERNATIONAL EQUITY INDEX FUND, AND VANGUARD
                   QUANTITATIVE PORTFOLIOS. If you experience difficulty in
                   making a telephone exchange, your exchange request may be
                   made by regular or express mail, and it will be implemented
                   at the closing net asset value on the date received by
                   Vanguard provided the request is received in Good Order.
 
                   Neither the Funds nor Vanguard is responsible for the
                   authenticity of exchange instructions received by telephone.
                   Investors bear the full risk of any loss arising from
                   unauthorized telephone exchanges. To prohibit telephone
                   exchanges on your account, please notify the Fund in writing.
                   Otherwise, the telephone exchange privilege will be
                   automatically established for your account.

IMPORTANT EXCHANGE
INFORMATION        Before you make an exchange, you should consider the
                   following:
 
                   - Please read the Fund's prospectus before making an
                     exchange. For a copy and for answers to any questions you
                     may have, call our Investor Information Department
                     (1-800-662-7447).
 
                   - An exchange is treated as a redemption and a purchase.
                     Therefore, you could realize a taxable gain or loss on the
                     transaction.
 
                   - Exchanges are accepted only if the registrations and the
                     Taxpayer Identification numbers of the two accounts are
                     identical.
 
   
                   - New accounts are not currently accepted in 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
                     all required documentation in Good Order.

<PAGE>   101
 
                   - When opening a new account by exchange, you must meet the
                     minimum investment requirement of the new Fund.
 
                   Every effort will be made to maintain the exchange privilege.
                   However, the Fund reserves the right to revise or terminate
                   its provisions, 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 Funds are registered for sale. The Funds
                   shares are currently registered for sale in all 50 states and
                   each Fund intends to maintain such registration.
- --------------------------------------------------------------------------------
 
EXCHANGE
PRIVILEGE
LIMITATIONS        The Fund's exchange privilege is not intended to afford
                   shareholders a way to speculate on short-term movements in
                   the market. Accordingly, in order to prevent excessive use of
                   the exchange privilege that may potentially disrupt the
                   management of the Fund and increase transaction costs, the
                   Fund has established a policy of limiting excessive exchange
                   activity.
 
                   Exchange activity generally will not be deemed excessive if
                   limited to TWO SUBSTANTIVE EXCHANGE REDEMPTIONS (AT LEAST 30
                   DAYS APART) from a Portfolio of the Fund during any twelve
                   month period. Notwithstanding these limitations, the Fund
                   reserves the right to reject any purchase request (including
                   exchange purchases from other Vanguard portfolios) that is
                   reasonably deemed to be disruptive to efficient portfolio
                   management.

IMPORTANT
INFORMATION
ABOUT TELEPHONE
TRANSACTIONS       The ability to initiate redemptions (except wire redemptions)
                   and exchanges by telephone is automatically established on
                   your account unless you request in writing that telephone
                   transactions on your account not be permitted. The ability to
                   initiate wire redemptions by telephone will be established on
                   your account only if you specifically elect this option in
                   writing.
 
                   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
                      by mail will be made payable to the registered shareowner
                      and mailed to the address of record, only. In the case of
                      a telephone redemption by wire, the wire transfer will be
                      made only in accordance with the shareowner's prior
                      written instructions.
 
   
                   Neither the Fund nor Vanguard will be responsible for the
                   authenticity of transaction instructions received by
                   telephone, provided that reasonable security procedures have
                   been followed. Vanguard believes that the security procedures
                   described above are reasonable, and that if such procedures
                   are followed, you will bear the risk of any losses resulting
                   from unauthorized or fraudulent telephone transactions on
                   your account.

                       INVESTMENT OBJECTIVE AND POLICIES
 
     REPURCHASE AGREEMENTS  Each Portfolio along with the other members of The
Vanguard Group, may invest in repurchase agreements with commercial banks,
brokers or dealers to generate income from its excess cash balances. A
repurchase agreement is an agreement under which a 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
seller, 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 a Portfolio and
is unrelated to the interest rate on the underlying instrument. In these
transactions, the securities acquired by a 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 the Fund's repurchase
agreement transactions generally and will establish guidelines and standards for
review of the creditworthiness of any bank, broker or dealer party to a
repurchase agreement with a Portfolio. 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. A Portfolio will enter into repurchase agreements
only with Federal Reserve member banks with minimum assets of at least $2
billion or registered securities dealers.
 
     The use of repurchase agreements involves certain risks. For example, if
the other party to the agreement defaults on its obligation to repurchase the
underlying security at a time when the value of the security has declined, the
Fund may incur a loss upon disposition of the security. If the other party to
the agreement becomes insolvent and subject to liquidation or reorganization
under the Bankruptcy Code or other laws, a court may determine that the
underlying security is collateral for a loan by a Portfolio not within the
control of the Portfolio and therefore the Portfolio may not be able to
substantiate its interest in the underlying security
 
                                       B-1
<PAGE>   105
 
and may be deemed an unsecured creditor of the other party to the agreement.
While the Fund's management acknowledges these risks, it is expected that they
can be controlled through careful monitoring procedures.
 
     LENDING OF SECURITIES  Each Portfolio may lend its securities to qualified
institutional investors who need to borrow securities in order to complete
certain transactions, such as covering short sales, avoiding failures to deliver
securities or completing arbitrage operations. By lending its portfolio
securities, 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. A Portfolio may lend its portfolio securities to
qualified brokers, dealers, banks or other financial institutions, so long as
the terms, the structure and the aggregate amount of such loans are 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 required that (a) the borrower pledge
and maintain with the Fund collateral consisting of cash, a letter of credit
issued by a domestic U.S. bank, or securities issued or guaranteed by the United
States Government having 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 a 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. Loan arrangements made by a Portfolio 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. 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.
 
     FUTURES CONTRACTS, OPTIONS ON FUTURES CONTRACTS, WARRANTS, CONVERTIBLE
SECURITIES AND SWAP AGREEMENTS  Each Portfolio may enter into futures contracts,
warrants, options on futures contracts, convertible securities and swap
agreements for the purpose of remaining fully invested and reducing transactions
costs. Futures contracts provide for the future sale by one party and purchase
by another party of a specified amount of a specific security at a specified
future time and at a specified price. Futures contracts which are standardized
as to maturity date and underlying financial instrument are traded on national
futures exchanges. The Fund's trading of futures contracts and options is
regulated under the Commodity Exchange Act by the Commodity Futures Trading
Commission ("CFTC"), a U.S. Government Agency.
 
     The Fund will "under normal circumstances" invest at least 80% of each
Portfolio's assets in stocks represented in its respective index. However, the
Fund has given itself the flexibility to invest up to 50% in futures and options
under other than normal circumstances. Any investment in futures and options
over 20% of a Portfolio's assets would be made in emergency situations, for
short-term purposes. Each Portfolio would normally remain 80% invested in stocks
that represent its respective index.
 
     Although futures contracts by their terms call for actual delivery or
acceptance of the underlying securities, in most cases the contracts are closed
out before the settlement date without the making or taking of delivery. Closing
out an open futures position is done by taking an opposite position ("buying" a
contract which has previously been "sold", or "selling" a contract previously
"purchased") in an identical contract to terminate the position. Brokerage
commissions are incurred when a futures contract is closed.
 
     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
deposits which may range upward from less than 5% of the value of the contract
being traded.
 
     After a futures contract position is opened, the value of the contract is
marked to market daily. If the futures contract price changes to the extent that
the margin on deposit does not satisfy margin requirements,
 
                                       B-2
<PAGE>   106
 
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.
 
     Each Portfolio will use futures contracts and options to simulate full
investment in the underlying index while retaining a cash balance for Fund
management purposes.
 
     Regulations of the CFTC applicable to the Fund 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, the
Fund expects that approximately 75% of its futures contract purchases will be
"completed," that is, equivalent amounts of related securities will have been
purchased or are being purchased by a Portfolio upon sale of open futures
contracts.
 
     Although techniques other than the sale and purchase of futures contracts
could be used to control a Portfolio's exposure to market fluctuations, the use
of futures contracts may be a more effective means of hedging this exposure.
While each Portfolio will incur commission expenses in closing out futures
positions, these costs are lower than transaction costs incurred in the purchase
and sale of the underlying securities.
 
     RESTRICTIONS ON THE USE OF FUTURES CONTRACTS  A 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 a Portfolio's total assets. Assets committed to futures or
options will be held in a segregated account at the Fund's custodial bank.
 
     RISK FACTORS IN FUTURES TRANSACTIONS  Positions in futures contracts may be
closed out only on an exchange which provides a secondary market for such
futures. However, there can be no assurance that a liquid secondary market will
exist for any particular futures contract at any specific time. Thus, it may not
be possible to close a futures position. In the event of adverse price
movements, a Portfolio would continue to be required to make daily cash payments
to maintain its required margin. In such situations, if a 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, a
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 the Portfolio.
 
     A Portfolio will minimize the risk that it will be unable to close out a
futures contract by only entering into futures which are traded on national
futures exchanges and for which there appears to be a liquid secondary market.
 
     The risk of loss in trading futures contracts in some strategies can be
substantial, due both to the low margin deposits required, and the extremely
high degree of leverage involved in futures pricing. As a result, a relatively
small price movement in a futures contract may result in immediate and
substantial loss (as well as gain) to the investor. For example, if at the time
of purchase, 10% of the value of the futures contract is deposited as margin, a
subsequent 10% decrease in the value of the futures contract would result in a
total loss of the margin deposit, before any deduction for the transaction
costs, if the account were then closed out. A 15% decrease would result in a
loss equal to 150% of the original margin deposit if the contract were closed
out. Thus, a purchase or sale of a futures contract may result in losses in
excess of the amount invested in the contract. However, because the futures
strategies of each Portfolio are engaged in only for hedging purposes, the
adviser does not believe that a Portfolio is subject to the risks of loss
frequently associated with futures transactions. A Portfolio would presumably
have sustained comparable losses if, instead of the futures contacts, it had
invested in the underlying financial instrument and sold it after the decline.
 
     Utilization of futures transactions by each Portfolio does involve the risk
of imperfect or no correlation where the securities underlying futures contracts
have different maturities than the portfolio securities being hedged. It is also
possible that a Portfolio could both lose money on futures contracts and also
experience a decline in value of its portfolio securities. There is also the
risk of loss by the fund of margin deposits in the event of bankruptcy of a
broker with whom a Portfolio has an open position in a futures contract or
related
 
                                       B-3
<PAGE>   107
 
option. Additionally, investments in futures and options involve the risk that
the investment adviser will incorrectly predict stock market and interest rate
trends.
 
     Most futures exchanges limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price at the end of a trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price beyond that limit. The daily limit governs only
price movement during a particular trading day and therefore does not limit
potential losses, because the limit may prevent the liquidation of unfavorable
positions. Futures contract prices have occasionally moved to the daily limit
for several consecutive trading days with little or no trading, thereby
preventing prompt liquidation of future positions and subjecting some futures
traders to substantial losses.
 
     SWAP AGREEMENTS  Swap agreements are contracts between parties in which one
party agrees to make payments to the other party based on the change in market
value of a specified index or asset. In return, the other party agrees to make
payments to the first party based on the return of a different specified index
or asset. Although swap agreements entail the risk that a party will default on
its payment obligations thereunder, the Portfolio will minimize this risk by
entering into agreements that mark to market no less frequently than quarterly.
Swap agreements also bear the risk that the Portfolio will not be able to meet
its obligation to the counterparty. This risk will be mitigated by investing the
Portfolio in the specific asset for which it is obligated to pay a return.
 
   
     FEDERAL TAX TREATMENT OF FUTURES CONTRACTS  Each Portfolio is required for
federal income tax purposes to recognize as income for each taxable year its net
unrealized gains and losses on certain futures contracts as of the end of the
year as well as those actually realized during the year. In most cases, any gain
or loss recognized with respect to a futures contract is considered to be 60%
long-term capital gain or loss and 40% short-term capital gain or loss, without
regard to the holding period of the contract. Furthermore, sales of futures
contracts which are intended to hedge against a change in the value of
securities held by a Portfolio may affect the holding period of such securities
and, consequently, the nature of the gain or loss on such securities upon
disposition. A Portfolio may be required to defer the recognition of losses on
futures contracts to the extent of any unrecognized gains on related positions
held by the Portfolio.
    
 
   
     In order for a 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, gains from the sale of
securities or of foreign currencies or other income derived with respect to the
Portfolio's business of investing in securities. In addition, gains realized on
the sale or other disposition of securities held for less than three months must
be limited to less than 30% of the 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, a 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 sales of 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 distributions.

                             INVESTMENT LIMITATIONS
 
     The following restrictions and fundamental policies cannot be changed
without approval of the holders of a majority of the outstanding shares of each
Portfolio (as defined in the Investment Company Act of 1940). A Portfolio may
not:
 
      1) invest in commodities or purchase real estate, although it may purchase
         securities of companies which deal in real estate or interest therein,
         and it may invest in stock index futures contracts, stock futures
         contracts, foreign currency futures contracts and options and warrants
         thereon to the extent that not more than 5% of its assets are required
         as deposit to secure obligations under such futures contracts;
 
      2) purchase securities on margin or sell securities short (the deposit or
         payment by the Fund of initial or variation margin in order to engage
         in an interest-rate futures contract is not considered the purchase of
         a security on margin);
 
      3) purchase more than 10% of the outstanding voting securities of any
         issuer;
 
      4) with respect to 75% of its assets invest more than 5% of the value of
         its total assets in the securities of any single issuer except
         obligations of the U.S. Government and its instrumentalities;
 
      5) borrow money, except from a bank and only as a temporary or emergency
         measure and in no event in excess of 15% of total assets taken at the
         lower of their value or cost;
 
      6) pledge, mortgage, or hypothecate any of its assets to an extent greater
         than 5% of the value of its total assets;
 
      7) issue senior securities (collateral arrangements with regard to initial
         and variation margin on futures contracts shall not be considered
         issuance of a senior security);
 
      8) engage in the business of underwriting securities issued by other
         persons, except to the extent that the Fund may technically be deemed
         to be an underwriter under the Securities Act of 1933, as amended, in
         disposing of portfolio securities;
 
      9) purchase or otherwise acquire any security if, as a result, more than
         15% of its net assets would be invested in securities that are illiquid
         (including any investment in the Vanguard Group, Inc.);
 
     10) invest for the purpose of controlling management of any company;
 
     11) invest in securities of other investment companies, except as may be
         acquired as a part of a merger, consolidation or acquisition of assets
         approved by the Fund's shareholders or otherwise to the extent
         permitted by Section 12 of the Investment Company Act of 1940. The
         Portfolio will invest only in investment companies which have
         investment objectives and investment policies consistent with those of
         the Fund;
 
   
     12) have dealings on behalf of the fund with Officers and Directors of the
         Fund, except for the purchase or sale of securities on an agency or
         commission basis;
    
 
     13) make loans to any officers, directors or employees of the Fund;
 
     14) invest in assessable securities or securities involving unlimited
         liability on the part of the holders thereof;
 
     15) make loans except (i) by purchasing bonds, debentures or similar
         obligations (including repurchase agreements, which are either publicly
         distributed or customarily purchased by institutional investors) and
         (ii) by lending its securities to banks, brokers, or dealers and other
         financial institutions so long as such loans are not inconsistent with
         the Investment Company Act or the Rules and Regulations or
         interpretations of the Securities and Exchange Commission thereunder;
 
     16) invest directly in oil, gas or other mineral exploration or development
         programs.
 
     These limitations are considered at the time investment securities are
purchased.
 
                                       B-5
<PAGE>   109
 
   
     Although not fundamental policies subject to shareholder vote, as long as a
Portfolio's shares are registered for sale in certain states, it will not (i)
invest more than 5% of the assets of a Portfolio, at the time of investment, in
the securities of any issuers which have (with predecessors) a record of less
than three years' continuous operation, and (ii) purchase or retain any security
if one or more officers, trustees or partners of a Portfolio or its investment
adviser individually own or would own, directly or beneficially, more than 1/2
of 1 per cent of the securities of such issuer, and in the aggregate such
persons own or would own more than 5% of such securities. Notwithstanding these
limitations, a Portfolio may own all or any portion of the securities of, or
make loans to, or contribute to the costs or other financial requirements of any
company which will be wholly owned by the Fund and one or more other investment
companies and is primarily engaged in the business of providing, at-cost,
management, administrative, distribution or related services to the Fund and
other investment companies. See "The Vanguard Group."
    
 
                               PURCHASE OF SHARES
 
   
     The Fund reserves the right in its sole discretion (i) to suspend the
offerings of its shares, (ii) to reject purchase orders when in the judgment of
management such rejection is in the best interests of the Fund, and (iii) to
reduce or waive the minimum for initial and subsequent investments as well as
redemption fees for certain fiduciary accounts or under circumstances where
certain economies can be achieved in sales of the Fund's shares.
    
 
                              REDEMPTION OF SHARES
 
     The Fund may suspend redemption privileges or postpone the date of payment
(i) during any period that the New York Stock Exchange is closed, or trading on
the Exchange is restricted as determined by the Securities and Exchange
Commission (the "Commission"), (ii) during any period when an emergency exists
as defined by the rules of the Commission as a result of which it is not
reasonably practicable for the Fund to dispose of securities owned by it, or
fairly to determine the value of its assets, and (iii) for such other periods as
the Commission may permit.
 
     The Fund has made an election with the Commission to pay in cash all
redemptions requested by any shareholder of record limited in amount during any
90-day period to the lesser of $250,000 or 1% of the net assets of the Fund at
the beginning of such period. Such commitment is irrevocable without the prior
approval of the Commission. Redemptions in excess of the above limits may be
paid, in whole or in part, in investment securities or in cash, as the Directors
may deem advisable; however, payment will be made wholly in cash unless the
Directors believe that economic or market conditions exist which would make such
a practice detrimental to the best interests of the Fund. If redemptions are
paid in investment securities, such securities will be valued as set forth in
the Prospectus under "The Share Price of Each Portfolio" and a redeeming
shareholder would normally incur brokerage expenses if he converted these
securities to cash.
 
     No charge is made by the Fund for redemptions from the European and Pacific
Portfolios. There is a 1% redemption transaction fee charged for redemptions
from the Emerging Market Portfolio. The redemption transaction fee is paid to
the Portfolio to reimburse the Portfolio for transaction costs it incurs while
liquidating securities in order to fund redemptions. Any redemption may be more
or less than the shareholder's cost depending on the market value of the
securities held by a Portfolio of the Fund.
 
                               THE VANGUARD GROUP
 
     The Fund is a member of The Vanguard Group of Investment Companies, which
consists of over 30 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
certain Vanguard Funds.
 
                                       B-6
<PAGE>   110
 
     Vanguard employs a supporting staff of management and administrative
personnel needed to provide the requisite services to the Funds and also
furnishes the Funds with necessary office space, furnishings and equipment. Each
Fund pays its share of Vanguard's net expenses, which are allocated among the
Funds under methods approved by the Board of Directors (Trustees) of each Fund.
In addition, each Fund bears its own direct expenses, such as legal, auditing
and custodian fees.
 
     The Fund's Officers are also Officers and employees of Vanguard. No Officer
or employee owns, or is permitted to own, any securities of any external adviser
for the Funds.
 
   
     The Vanguard Group adheres to a Code of Ethics established pursuant to Rule
17j-1 under the Investment Company Act of 1940. The Code is designed to prevent
unlawful practices in connection with the purchase or sale of securities by
persons associated with Vanguard. Under Vanguard's Code of Ethics certain
officers and employees of Vanguard who are considered access persons are
permitted to engage in personal securities transactions. However, such
transactions are subject to procedures and guidelines substantially similar to
those recommended by the mutual fund industry and approved by the U.S.
Securities and Exchange Commission.
    
 
   
     The Vanguard Group was established and operates under a Funds' Service
Agreement which was approved by the shareholders of each of the Funds. The
amounts which each of the Funds 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. The Fund's Service
Agreement provides as follows: (a) each Vanguard Fund may invest up to 0.40% of
its current net assets in Vanguard and (b) there is no other limitation on the
amount that each Vanguard Fund may contribute to Vanguard's Capitalization. At
December 31, 1994, the Fund had contributed capital of $231,000 to Vanguard,
representing 1.2% of 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. The Fund's
share of Vanguard's actual net costs of operation relating to management and
administrative services (including transfer agency) for the year ended December
31, 1994 totaled approximately $2,891,000.
    
 
     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 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
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 December 31, 1994, the Fund paid
approximately $270,000 of the Group's distribution and marketing expenses, which
represented an effective annual rate of .01 of 1% of its average month-end net
assets.
    
 
   
     INVESTMENT ADVISORY SERVICES  Vanguard's Core Management Group provides
investment advising services to the Fund and also to the following Funds:
Vanguard Index Trust, Vanguard Balanced Index Fund, the Growth and Income and
Capital Appreciation Portfolios and the equity portion of the Balanced Portfolio
of the Vanguard Tax-Managed Fund, Vanguard Institutional Index Fund, a portion
of the assets of

Vanguard/Windsor II, the Equity Index Portfolio of the Vanguard Variable
Insurance Fund, a portion of Vanguard/Morgan Growth Fund and several indexed
separate accounts.
    
 
   
     Vanguard's Fixed Income Group also provides investment advisory services to
the following Funds: Vanguard Municipal Bond Fund; Vanguard Money Market
Reserves; several Portfolios of Vanguard Fixed Income Securities Fund; Vanguard

Fund; and Vanguard Institutional Money Market Portfolio. These services are
provided on an at-cost basis by the Fixed Income Group. The compensation and
other expenses of this staff are paid by the Funds utilizing these services.
During the fiscal year ended December 31, 1994, the Fund paid approximately
$161,000 of Vanguard's expenses relating to investment advisory services.
    
 
   
     REMUNERATION OF DIRECTORS AND OFFICERS  The Fund pays each Director, who is
not also an Officer, an annual fee plus travel and other expenses incurred in
attending Board meetings. The Fund's Officers and employees are paid by Vanguard
which, in turn, is reimbursed by the Fund and each other Fund in the Group, for
its proportionate share of Officers' and employees' salaries and retirement
benefits. The Fund's proportionate share of remuneration paid to Officers for
the year ended December 31, 1994 was $--. Under its retirement plan, Vanguard
contributes annually an amount equal to 10% of each Officer's annual
compensation plus 5.7% of that part of the Officer's compensation during the
year, if any, that exceeds the Social Security Taxable Wage Base then in effect.
Directors who are not officers are paid an annual fee upon retirement equal to
$1,000 for each year of service on the Board up to a maximum of 15 years. The
Fund's proportionate share of retirement contributions for its Officers for the
year ended December 31, 1994 was approximately $--.

                             PORTFOLIO TRANSACTIONS
 
     In placing portfolio transactions, the Fund uses 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 are considered in making these
determinations. In those instances where it is reasonably determined that more
than one broker can offer the brokerage services needed
 
                                       B-9
<PAGE>   113
 
to obtain the best available price and most favorable execution, consideration
will be given to those brokers which supply statistical information and provide
other services in addition to execution services to the Fund.
 
   
     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, the Fund may place portfolio orders with qualified
broker-dealers who recommend the Fund to clients, and may, when a number of
brokers and dealers can provide best price and execution on a particular
transaction, consider the sale of Fund shares by a broker or dealer in selecting
among broker-dealers. For the years ended December 31, 1992, 1993 and 1994 the
Fund paid approximately $875,337, $1,781,395 and $1,559,349 in brokerage
commissions, respectively.
    
 
                              PERFORMANCE MEASURES
 
     The Fund may use one or more of the following unmanaged indexes for
comparative performance purposes:
 
MORGAN STANLEY CAPITAL INTERNATIONAL -- SELECT EMERGING MARKETS INDEX -- is an
unpublished index which includes common stocks of companies located in the
countries 12 emerging markets.
 
MORGAN STANLEY CAPITAL INTERNATIONAL -- EAFE (FREE) INDEX -- is an arithmetic,
market value-weighted average of the performance of over 1,000 securities listed
on the stock exchanges of countries in Europe, Australia and the Far East.
 
FT-ACTUARIES WORLD INDEX -- includes approximately 2,400 securities from 24
countries including the U.S.
 
FT-ACTUARIES EURO-PACIFIC INDEX -- a subset of the FT Actuaries World Index,
which excludes companies in the U.S., Canada, Mexico and South Africa.
 
SALOMON-RUSSELL PRIMARY MARKET INDEX -- consists of the approximately 700
largest stocks within 23 countries.
 
SALOMON-RUSSELL EXTENDED MARKET INDEX -- consists of approximately 1,000 medium

                              FOREIGN INVESTMENTS
 
     FOREIGN INVESTMENTS  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 Fund
may temporarily hold uninvested reserves in bank deposits in foreign currencies,
it will be affected favorably or unfavorably by changes in currency rates and in
exchange control regulations, and may incur costs in connection with conversions
between various currencies. The investment policies of the Fund permit it to
enter into forward foreign currency exchange contracts in order to hedge its
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.
 
     As foreign companies are not generally subject to uniform accounting,
auditing and financial reporting standards and practices comparable to those
applicable to domestic companies, there may be less publicly available
information about certain foreign companies than about domestic companies.
Securities of some foreign companies are generally less liquid and more volatile
than securities of comparable domestic companies. There is generally less
government supervision and regulation of stock exchanges, brokers and listed
companies than in the U.S. In addition, with respect to certain foreign
countries, there is the possibility of expropriation or confiscatory taxation,
political or social instability, or diplomatic developments which could affect
U.S. investments in those countries.
 
     Although the Fund will endeavor to achieve most favorable execution costs
in its portfolio transactions, 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 Fund's
foreign securities will be somewhat greater than the expenses for a Fund that
invests primarily in domestic securities.
 
     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 Portfolio.
 
     Over the last decade the growth in the international stock markets has
considerably outpriced that of the U.S. Stock Market. Almost two-thirds of the
worlds equity market capitalization now lies outside the United States.

     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 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.
