INVESTMENT                 Vanguard Specialized Portfolios, Inc. (the "Fund") is an open-end
OBJECTIVE                  diversified investment company. The Fund consists of four Portfolios that
AND POLICIES               invest primarily in common stocks and other equity securities concentrated
                           in a particular industry or group of related industries. Three Portfolios
                           of the Fund (Energy, Gold & Precious Metals and Health Care) seek to
                           provide long-term capital appreciation. A fourth Portfolio (Utilities
                           Income) seeks to provide current income and moderate growth of capital and
                           income. There is no assurance that any Portfolio will achieve its stated
                           objective. Given their specialized focus, the Portfolios should not be
                           considered a complete investment program. The Fund is offered on a no-load
                           basis (i.e., there are no sales commissions or 12b-1 fees). However, the
                           Fund incurs expenses for investment advisory, management, administrative,
                           and distribution services.

                                           HIGHLIGHTS
OBJECTIVE AND             The Fund is an open-end diversified investment company. The Fund
POLICIES                  consists of four Portfolios that invest primarily in common stocks and
                          other equity securities concentrated in a particular industry or group
                          of related industries. Three Portfolios of the Fund (Energy, Gold &
                          Precious Metals and Health Care) seek to provide long-term capital
                          appreciation. A fourth Portfolio (Utilities Income) seeks to provide
                          current income and moderate growth of capital and income. There is no
                          assurance that any Portfolio will achieve its stated objective.    
                                                                                           PAGE 8
- -------------------------------------------------------------------------------------------------
RISK                      Each Portfolio of the Fund is subject to market risk and industry risk.
CHARACTERISTICS           Market risk is the possibility that stock prices will decline over
                          short or even extended periods. The stock market tends to be cyclical,
                          with periods when stock prices generally rise and periods when stock
                          prices generally decline. Each Portfolio is expected to be strongly
                          influenced by these broad fluctuations in stock prices.
                          In addition, unlike more widely diversified mutual funds, the
                          Portfolios are subject to industry risk, the possibility that a
                          particular group of related stocks will decline in price due to
                          industry-specific developments. Securities held by the Energy Portfolio
                          will be influenced by cyclical fluctuations in the supply and demand
                          for oil, as well as tax and regulatory policies, conservation trends,
                          and international oil politics. The Gold & Precious Metals Portfolio
                          will be subject to the highly volatile and often erratic markets for
                          gold and precious metals and for the common stocks of mining companies.
                          Investments relating to gold and precious metals or minerals are
                          considered speculative, and are affected by a host of world-wide
                          economic, financial and political factors. Stocks held by the Health
                          Care Portfolio will be affected by government policies on health care
                          reimbursements, regulatory approval for new drugs and medical
                          instruments, and similar matters.
                          Industry risks in the Utilities Income Portfolio include: changing
                          utility regulation, new competitive pressures, and rising operating
                          costs, on top of unique risks for telephone, electric, gas and water
                          utilities. The Utilities Income Portfolio is also exposed to interest
                          rate risk--price fluctuations due to changing interest rates. More so
                          than other stock market sectors, utility stocks may sometimes behave
                          like fixed income investments, rising and falling as interest rates
                          change.
                                                                                          PAGE 10

DIVIDENDS, CAPITAL        Dividends of net investment income are expected to be made quarterly
GAINS AND TAXES           for the Utilities Income Portfolio, and annually for the Energy, Gold &
                          Precious Metals and Health Care Portfolios. Capital gains, if any, will
                          be distributed annually. Dividend and capital gains distributions are

                          sale of shares--whether by outright redemption or exchange--is a
                          taxable event and may result in a capital gain or loss.

PURCHASING                You may purchase shares by mail, wire, or exchange from another
SHARES                    Vanguard Fund. The minimum initial investment is $3,000 per Portfolio;
                          the minimum for subsequent investments is $100. There are no sales
                          commissions or 12b-1 fees.
                                                                                          PAGE 24

SELLING SHARES            You may redeem shares of each Portfolio by mail or by telephone. The
                          Energy, Gold & Precious Metals and Health Care Portfolios assess a 1%
                          redemption fee, on shares held less than 12 months. (The Utilities
                          Income Portfolio does not assess a 1% redemption fee.) Each Portfolio's
                          share price is expected to fluctuate, and at the time of redemption may
                          be more or less than at the time of initial purchase, resulting in a
                          gain or loss.                         
                                                                                          PAGE 27

EXCHANGING                You may exchange a Portfolio's shares for those of another Portfolio of
SHARES                    the Fund or other Vanguard Funds. An exchange from the Energy, Gold &
                          Precious Metals, and Health Care Portfolios will be subject to a 1%
                          redemption fee if held for less than 12 months. (The Utilities Income
                          Portfolio does not assess a 1% redemption fee.)
                                                                                          PAGE 29

SPECIAL                   (1) Under normal circumstances, at least 80% of the assets of each
CONSIDERATIONS            Portfolio (75% in the case of the Utilities Income Portfolio) will be
                          invested in equity securities concentrated in a particular industry or
                          group of industries. As a result, a Portfolio of the Fund may be
                          subject to greater fluctuations in market value than a mutual fund
                          which invests in a more widely diversified group of stocks. Due to the
                          specialized focus of the individual Portfolios, an investment in a
                          Portfolio should not be considered a complete investment program.
                          (2) The Gold & Precious Metals Portfolio may invest all of its assets
                          in foreign securities, and each of the other Portfolios of the Fund may
                          invest a portion of its assets in foreign securities. Each Portfolio
                          may enter into forward foreign exchange contracts in order to protect
                          against uncertainty in the level of future foreign exchange rates, but
                          not for speculative purposes.                  
                                                                                           PAGE 8
                          (3) Each Portfolio may lend its securities.
                                                                                          PAGE 16

                            for each of these Portfolios. In future years, the Portfolios will pay these fees and
                            costs to the extent that they are not offset by redemption fees.

1% REDEMPTION FEE         The Energy, Gold & Precious Metals and Health Care Portfolios are
                          intended for long-term investors who can withstand substantial price
                          fluctuation. For this reason, the Portfolios will assess a 1%
                          redemption fee on shares that are redeemed or exchanged out before they
                          have been held for one year. Solely for purposes of calculating the one
                          year holding period the Portfolio will use the "first-in, first-out"
                          (FIFO) method. That is, the date of the redemption or exchange will be
                          compared to the earliest purchase date. If this holding period is less
                          than one year, the fee will be assessed. The fee will be prorated if a
                          portion of the shares being redeemed or exchanged has been held for
                          more than one year. This fee will not apply to dividend or capital gain
                          reinvestment and it is paid directly to the Portfolio. The Utilities
                          Income Portfolio does not assess the 1% fee.
                          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. This example
                          takes into account the 1% fee that applies to redemptions from the
                          Energy, Gold & Precious Metals, and Health Care Portfolios or exchanges
                          from these Portfolios to another Vanguard Fund or Portfolio (including
                          the Utilities Income Portfolio).

YIELD AND                 From time to time a Portfolio may advertise its yield and total return.
TOTAL RETURN              Both yield and total return figures are based on historical earnings and

                          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.
                          The "30-day yield" of a Portfolio is calculated by dividing net
                          investment income per share earned during a 30-day period by the net
                          asset value per share on the last day of the period. Net investment
                          income includes interest and dividend income earned on 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 or the yield reported in a Portfolio's financial statements.
                          Also, the Portfolios may compare their performance to that of various
                          stock market indices, including the Standard & Poor's 500 Index.

INVESTMENT                The Fund is an open-end diversified investment company. The Fund
OBJECTIVE                 consists of four Portfolios that invest primarily in common stocks and
THREE PORTFOLIOS SEEK     other equity securities concentrated in a particular industry or group
  TO PROVIDE LONG-TERM    of related industries.
GROWTH; A FOURTH          The Energy, Gold & Precious Metals, and Health Care Portfolios seek to
PORTFOLIO SEEKS           provide long-term capital appreciation. Although these three Portfolios
CURRENT INCOME            may generate dividend income to a limited extent, current income will be
                          secondary to these Portfolios' primary objective of achieving capital
                          appreciation.
                          The Utilities Income Portfolio, in contrast, seeks to provide current
                          income as its primary objective. Its secondary objective is to provide
                          moderate growth of capital and income over time.
                          There is no assurance that any Portfolio of the Fund will achieve its
                          stated objective.
                          The investment objective of each Portfolio is fundamental and so cannot
                          be changed without the approval of a majority of a Portfolio's
                          shareholders.
- --------------------------------------------------------------------------------------------------
INVESTMENT                Under normal circumstances, the Energy, Gold & Precious Metals, and
POLICIES                  Health Care Portfolios will each invest at least 80% of their net assets
EACH PORTFOLIO INVESTS    in the equity securities (common stocks and securities convertible into
IN INDUSTRY-SPECIFIC      common stocks) of companies in a particular industry or group of related
COMMON STOCKS             industries. The Gold & Precious Metals Portfolio may also invest in gold
                          or other precious metal bullion and coins. A security will generally be
                          considered appropriate for a given Portfolio if, as determined by the
                          investment adviser, at least 50% of the company's assets, revenues or
                          net income are related to or derived from the industry or industries
                          designated for the Portfolio. The Fund is managed without regard to tax
                          ramifications.
                          Under normal circumstances, the Utilities Income Portfolio will invest
                          at least 75% of its assets in equity securities of companies in the
                          utilities industry. The remainder of the Portfolio's assets will be
                          invested in utility bonds rated A or better by Standard & Poor's
                          Corporation or Moody's Investors Service. Because of its emphasis on
                          higher-yielding utility stocks and its holdings of utility bonds, the
                          Portfolio is expected to offer a dividend yield well above the stock
                          market average.
                          The Portfolios of the Fund will invest primarily in securities that
                          trade in U.S. markets. However, the Gold & Precious Metals Portfolio may
                          invest up to 100% of its assets in foreign securities, and each other
                          Portfolio may invest up to 20% of its assets in foreign securities.
                          (Note, however, that the Utilities Income Portfolio has no present
                          intention of investing more than 10% of its assets in foreign
                          securities.) In order to protect against fluctuations in foreign
                          exchange rates, each Portfolio may invest in forward foreign currency
                          exchange contracts.
                          Besides investing primarily in equity securities, each Portfolio may
                          hold certain short-term fixed income securities as cash reserves. Each
                          Portfolio may also invest in stock futures contracts and options to a
                          limited extent. See "Implementation of Policies" for a description of
                          these and other investment practices of the Fund.

                          The specific investment policies of the four Portfolios are listed
                          below:
                          The Energy Portfolio invests in the equity securities of companies
                          engaged in the following energy-related activities: the production,
                          transmission, marketing, control or measurement of energy or energy
                          fuels; the making of component products for such activities; energy
                          research or experimentation; and activities related to energy
                          conservation and pollution control. Such activities may involve newer
                          sources of energy, such as geothermal, nuclear and solar power, as well
                          as more traditional sources of energy, such as oil, natural gas and
                          coal. As new sources of energy are developed and current methods of
                          exploiting and developing energy are advanced, then companies in these
                          new areas will also be considered for the Energy Portfolio. The
                          Portfolio, however, will not purchase the securities of electric utility
                          companies, although it may invest in natural gas distributors and
                          natural gas pipeline concerns.
                          The Gold & Precious Metals Portfolio invests in the equity securities of
                          foreign and domestic companies engaged in the exploration, mining,
                          fabrication, processing, or marketing and distribution of gold, silver,
                          platinum, diamonds or other precious and rare metals and minerals. The
                          Portfolio may also invest up to 20% of its assets directly in gold,
                          silver or other precious metal bullion and coins.
                          Bullion and coins for the Gold & Precious Metals Portfolio will only be
                          bought from and sold to banks (both U.S. and foreign), and dealers who
                          are members of, or affiliated with members of, a regulated U.S.
                          commodities exchange, in accordance with applicable investment laws.
                          Gold, silver or other precious metal bullion will not be purchased in
                          any form that is not readily marketable. Coins will not be purchased for
                          their numismatic value and will not be considered for the Portfolio if
                          they cannot be bought or sold in an active market. Any bullion or coins
                          purchased by the Portfolio will be delivered to and stored with a
                          qualified custodian bank in the U.S.
                          Investors should be aware that bullion and coins do not generate income,
                          offering only the potential for capital appreciation or depreciation,
                          and may subject the Portfolio to higher custody and transactions costs
                          than those normally associated with the ownership of securities.
                          Investments relating to gold and other precious metals or minerals are
                          considered speculative. See "Investment Risks."
                          The Health Care Portfolio invests in securities of companies engaged in
                          the development, production or distribution of products and services
                          related to the treatment or prevention of diseases and other medical
                          infirmities. Companies in these fields include, but are not limited to,
                          pharmaceutical firms; companies that design, manufacture or sell medical
                          supplies, equipment and support services; and companies that operate
                          hospitals and other health care facilities. The Portfolio will also
                          consider companies engaged in medical, diagnostic, biochemical, and
                          biotechnological research and development.
                          The Utilities Income Portfolio invests in equity and debt securities of
                          companies engaged in the generation, transmission, or distribution of
                          electricity, telecommunications, gas, or water. Such investments will
                          be selected on the basis of fundamen-

                          tal analysis to identify those securities that the adviser
                          believes will provide both current income and the potential for growth
                          in income and capital over time.
                          The utilities sector of the stock market, from which the Utilities
                          Income Portfolio's primary investments will be drawn, is dominated by
                          telephone and electric utility common stocks, with gas and water
                          companies playing an appreciably smaller role. For example, as of
                          January 31, 1994, the Standard & Poor's Utility Index was heavily
                          weighted towards telephone and electric stocks, as the following chart

                          Similarly, the market for utility bonds is dominated by telephone and
                          electric utility issuers. For example, as of March 31, 1994, telephone
                          company bonds represented 33% of the outstanding utility bonds rated A
                          or better (measured in terms of market value by the Lehman Brothers
                          Investment Grade Utility Bond Index). Electric utility issues accounted
                          for 35% of A-or-better utility bonds, while gas, water and other
                          utilities represented the remaining 32%.
                          Utilities are subject to strict regulatory oversight. However, in recent
                          years, changes in the regulatory climate have allowed utilities to
                          provide products and services outside their traditional geographic
                          areas, leading to increased competition and
                          expanded prospects for growth. The Portfolio seeks to take advantage of
                          favorable opportunities that are expected to arise from these structural
                          changes in regulation.

                          The investment policies of the Fund are not fundamental and so may be
                          changed by the Board of Directors without shareholder approval.
- --------------------------------------------------------------------------------------------------
INVESTMENT                As equity mutual funds specializing in specific industries or groups of
RISKS                     industries, the Portfolios of the Fund are subject primarily to two
EACH PORTFOLIO IS         types of risk: market risk and industry risk. Since the Portfolios may
SUBJECT TO MARKET AND     invest in foreign securities, investors are also exposed to currency
INDUSTRY RISK             risk and other risks of international investing.
                          Market risk is the possibility that stock prices in general will decline
                          over short or even extended periods. The stock market tends to be
                          cyclical, with periods when stock prices generally rise and periods when
                          stock prices generally decline. In the period from 1926 to 1993, stocks
                          have provided an average annual total return (capital appreciation plus
                          dividend income) of +12.3%, as measured by the Standard & Poor's 500
                          Composite Stock Price Index. In contrast, the return on stocks in
                          individual years has varied from a low of -43.3% to a high of +53.9%,
                          reflecting the short-term volatility of stock prices.
                          These fluctuations in stock market prices are expected to have a 
                          substantial influence on the value of each Portfolio. Moreover, the

                          Metals, and Health Care Portfolios are likely to exhibit greater volatility than 
                          the broad stock market, largely as a result of their industry-specific holdings 
                          and, in several of the Portfolios, an emphasis on the stocks of smaller companies.
                          By contrast, the Utilities Income Portfolio is expected to exhibit less
                          volatility than the stock market as a whole and the other Portfolios of
                          the Fund. Historically, utility stocks have been one of the least
                          volatile sectors of the stock market (when measured by such statistics
                          as standard deviation of returns or industry "beta"). Moreover, the
                          Portfolio's investment in utility bonds is expected to further dampen
                          the stock market's influence on the Portfolio. Of course, the
                          Portfolio's bond holdings will fluctuate in value, sometimes
                          substantially, as interest rates change.
                          In addition to stock market risk, each Portfolio is subject to industry
                          risk -- i.e., the possibility that a particular group of related stocks
                          will decline in price due to industry-specific developments. The special
                          industry risks of the Energy Portfolio are that earnings and dividends
                          of companies in the energy industry are greatly affected by changes in
                          the prices and supplies of oil and other energy fuels. Prices and
                          supplies can fluctuate significantly over a short period due to changes
                          in international politics, policies of the Organization of Petroleum
                          Exporting Countries (OPEC), relationships among OPEC members and between
                          OPEC and oil-importing nations, energy conservation, the regulatory
                          environment, governmental tax policies, and the economic growth and
                          stability of the main energy-consuming countries.
                          The industry risks of the Gold & Precious Metals Portfolio include the
                          sharp price volatility of gold and other precious metals and of mining
                          company shares. Investments related to gold or other precious metals or
                          minerals are considered speculative and are affected by a host of
                          world-wide economic, financial and political factors. Prices of gold and
                          other precious metals may fluctuate sharply over short periods due to
                          several factors: changes in inflation or expectations regarding
                          inflation in various countries; currency fluctuations; metal sales by
                          governments, central banks or international agencies; investment
                          speculation; changes in industrial and commercial demand; and
                          governmental prohibitions or restrictions on the private ownership of
                          certain precious metals or minerals.
                          Political and economic conditions in gold-producing countries may also
                          have a direct effect on the mining and distribution of gold and,
                          consequently, its price. At present, there are only four major producers
                          of gold bullion. In order of magnitude, they are: the Republic of South
                          Africa ("South Africa"), Russia, Canada and the United States.
                          Events in South Africa are of particular importance since the Portfolio
                          intends to invest a substantial portion of its assets in securities of
                          South African mining companies (22% of the Portfolio's net assets as of
                          January 31, 1994). In South Africa, the activities of gold-mining
                          companies are subject to policies promulgated by the Ministry of Mines.
                          The Reserve Bank of South Africa, as the sole authorized agent for South
                          African gold, influences the price and timing of sales of South
                          African gold. The South African government has also from time to time
                          imposed restrictions on the flow of international capital.

                          Political and social problems in South Africa may also pose certain
                          risks to the Portfolio's investments in South African issuers. These
                          include the effect of social and political unrest on mining production
                          and gold prices, as well as the threat of nationalization or
                          expropriation by the current or future government of South Africa. Other
                          risks include potential U.S. Government regulation of South African
                          investments.
                          The special industry risks of the Health Care Portfolio are that the
                          economic prospects of health care companies can fluctuate dramatically
                          due to changes in the regulatory and competitive environment. A
                          substantial portion of health care services are funded or subsidized by
                          the government, and so changes in governmental policies at the federal
                          or state level may affect the demand for health care products and
                          services. Regulatory approvals, which often entail lengthy application
                          and testing procedures, are generally required before new drugs and
                          certain medical instrumentation may be introduced. Health care companies
                          may face lawsuits related to product liability issues. Also, many
                          products and services provided by health care companies are subject to
                          rapid obsolescence.
                          For the Utilities Income Portfolio, changing regulation constitutes one
                          of the key industry-specific risks. Regulators (largely at the state
                          level) monitor and control utility revenues and costs, and therefore may
                          limit utility profits and dividends paid to investors. Regulatory
                          authorities may also restrict a company's access to new markets, thereby
                          diminishing the firm's long-term prospects. Individual sectors of the
                          utility market are subject to the following additional risks:
                          - Electric utilities may be burdened by unexpected increases in fuel and
                            other operating costs. They are also adversely affected when long-term
                            interest rates rise. Long-term borrowings are used to finance most
                            utility investment, and rising interest rates lead to higher financing
                            costs and reduced earnings. There are also the considerable costs
                            associated with environmental compliance, nuclear waste clean-up, and
                            safety regulation. Increasingly, electric utilities are being called
                            upon by regulators to bear these added costs, and there is a risk that
                            these costs will not be fully recovered through an increase in
                            revenues.
                          - Telephone utilities have been buffeted by technological development
                            leading to increased competition, as well as changing regulation of
                            long-distance telephone service and other telecommunications
                            businesses. While certain companies have benefitted from the new
                            competitive climate, others have not, and increased competition in the
                            future may hinder the growth of more traditionally oriented telephone
                            companies.
                          - Among gas transmission and distribution companies, there has been a
                            move to diversify into oil and gas exploration and development, making
                            investment returns more sensitive to energy prices. In the case of the
                            water utility sector, the industry is highly fragmented, and most water
                            supply companies find themselves in mature markets, with little potential
                            for growth.
                          The Utilities Income Portfolio is also subject to interest rate risk -- price
                          fluctuations due to changing interest rates. In general, fixed income
                          investments, such as

                          bonds, vary inversely with interest rates, falling in price 
                          when interest rates rise, and rising in price when interest 
                          rates fall. Utility stocks, more so than other stock
                          market sectors, are often influenced by these trends in interest rates,
                          rather than price movements in the broad stock market. At the same time,
                          the Portfolio's bond holdings are subject to interest rate risk. This
                          combination of interest-rate-sensitive stocks and bonds means that the
                          Portfolio may at times move in tandem with the bond market, rising and
                          falling as interest rates change, independent of the broad stock market.
                          Investors in the Utilities Income Portfolio should be aware that while
                          utility stocks have historically provided above-average dividend yields,
                          there is no guarantee that they will continue to do so in the future. As
                          of January 31, 1994, the Standard & Poor's Utility Index provided a
                          current yield of 5.1%, which was nearly two times as high as the yield
                          of 2.6% provided by the broad stock market (as measured by the Standard
                          & Poor's 500 Index). Many of the risks enumerated above have made it
                          increasingly difficult for utility companies to sustain such generous
                          dividend pay-outs, and future dividend yields of the utility sector
                          could decline.
                          Similarly, while utility stocks during recent years have provided total
                          investment returns (dividend yield plus capital change) above stock
                          market averages, there is again no guarantee that such returns will
                          continue. For example, during the ten-year period ended January 31,
                          1994, the Standard & Poor's Utility Index gained 17.1% per year on
                          average, while the Standard & Poor's 500 Index, a measure of the broad
                          stock market, returned 15.3% per year. Investors should recognize that a
                          period of above-average investment performance by a stock market sector,
                          such as that provided by utility stocks over the past ten years, is
                          often followed by a period of below-average investment performance. In
                          addition, investors should not anticipate that utility stocks will
                          outperform the broad stock market over the long haul, given the
                          generally limited growth prospects of the utilities industry.
EACH PORTFOLIO IS         The investment advisers manage each Portfolio according to the
SUBJECT TO MANAGER        traditional methods of "active" investment management, which involves
RISK                      the buying and selling of securities based upon economic, financial and
                          market analysis and investment judgment. Manager risk refers to the
                          possibility that each Portfolio's investment adviser may fail to execute
                          the Portfolio's investment strategy effectively. As a result, each
                          Portfolio may fail to achieve its stated objective.
FOREIGN SECURITIES        Since each Portfolio may invest in foreign securities, investors in the
ENTAIL CURRENCY AND       Fund are also exposed to the unique risks of international investing.
OTHER RISKS               For U.S. investors, the returns of foreign securities are influenced by
                          not only the returns on foreign common stocks themselves, but also by
                          currency risk -- i.e., changes in the value of the currencies in which
                          the stocks are denominated. In a period when the U.S. dollar rises
                          against foreign currencies, the returns on foreign stocks for a U.S.
                          investor are diminished. By contrast, in a period when the U.S. dollar 
                          declines, the returns on foreign stocks are enhanced.                                
                          Other risks and considerations of international investing include the  
                          following: differences in accounting, auditing and financial reporting 
                          standards; generally

                          higher commission rates on foreign portfolio transactions; 
                          the smaller trading volumes and generally lower liquidity
                          of foreign stock markets, which may result in greater price volatility;
                          foreign withholding taxes payable on a Portfolio's foreign securities,
                          which may reduce dividend income payable to shareholders; the
                          possibility of expropriation or confiscatory taxation; adverse changes
                          in investment or exchange control regulations; political instability
                          which could affect U.S. investment in foreign countries; difficulty in
                          obtaining and enforcing foreign court judgements; and potential
                          restrictions on the flow of international capital.

WHO SHOULD                The Fund is designed for investors who are seeking the potential
INVEST                    rewards, and who are willing to accept the risks, associated with equity
                          investments concentrated in specific industries. Because of the risks
                          associated with common stock and bond investments, the Fund is intended
                          to be a long-term investment vehicle and is not designed to provide
                          investors with a means of speculating on short-term stock and bond
                          market movements. Investors who engage in excessive account activity
                          generate additional costs which are borne by all of the Fund's
                          shareholders. In order to minimize such costs the Fund has adopted the
                          following policies. The Fund reserves the right to reject any purchase
                          request (including exchange purchases from other Vanguard portfolios)
                          that is reasonably deemed to be disruptive to efficient portfolio
                          management, either because of the timing of the investment or previous
                          excessive trading by the investor. Additionally, the Fund has adopted
                          exchange privilege limitations as described in the section "Exchange
                          Privilege Limitations." Finally, the Fund reserves the right to suspend
                          the offering of its shares.
                          The Energy, Gold & Precious Metals, and Health Care Portfolios are
                          intended for investors with substantial financial resources who have the
                          perspective and patience to assume above-average interim investment
                          risks in pursuit of long-term capital growth. Since many of the
                          securities owned by these three Portfolios may be considered speculative
                          in nature or unseasoned by traditional investment standards,
                          substantially greater-than-average investment risk is involved. The
                          share prices of these three Portfolios are expected to be volatile.
                          In contrast, the Utilities Income Portfolio is designed for investors
                          who are seeking a more conservative, income-oriented stock market
                          investment. The Portfolio is likely to offer higher dividend yields than
                          the stock market average, with substantially lower volatility in share
                          price. The Portfolio may also offer modest growth in income and capital
                          over time. Nonetheless, because utility stock and bond prices will
                          fluctuate, sometimes substantially, investors in the Utilities Income
                          Portfolio should be willing to accept moderate to high fluctuations in
                          principal value.
                          There can be no assurance that the Fund will achieve its stated
                          objective, or that shareholders will be protected from the substantial
                          risks inherent in equity investing. Investors may wish to reduce the
                          potential risk of investing in a Portfolio by purchasing shares on a 
                          periodic basis (dollar-cost averaging) rather than investing in one lump sum.
                          Since each Portfolio concentrates its holdings in a particular industry
                          or group of industries, the Fund should not be considered a complete   
                          investment program. Most

                          Precious Metals Portfolio may invest up to 100% of its assets, in
                          foreign securities. (At present, the Utilities Income Portfolio is not
                          expected to invest more than 10% of its net assets in foreign
                          securities.) Such a policy expands the investment opportunities
                          available to the Portfolios and may result in improved diversification
                          and performance.
                          All or a portion of the foreign securities purchased by a Portfolio may
                          be in the form of American Depository Receipts (ADRs) or European
                          Depository Receipts (EDRs). ADRs are receipts typically issued by a U.S.
                          bank or trust company that evidence ownership of underlying securities
                          issued by a foreign corporation. EDRs are receipts issued in Europe that
                          evidence a similar ownership arrangement. Generally, ADRs are designed
                          for trading in the United States securities markets and EDRs are
                          designed for trading in European securities markets.
EACH PORTFOLIO MAY        Each Portfolio of the Fund may enter into forward foreign currency
ENTER INTO FORWARD        exchange contracts in order to protect against uncertainty in the level
CURRENCY CONTRACTS        of future foreign exchange rates in the purchase and sale of investment
                          securities. A Portfolio may not enter into such contracts for
                          speculative purposes.
                          A forward foreign currency exchange contract is an obligation to
                          purchase or sell a specific currency at a future date, which may be any
                          fixed number of days from the date of the contract agreed upon by the
                          parties, at a price set at the time of the contract. These contracts may
                          be bought or sold to protect a 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.
EACH PORTFOLIO MAY        Although they normally seek to remain substantially fully invested in
INVEST IN SHORT-TERM      equity securities (except the Utilities Income Portfolio, which may
FIXED-INCOME              invest up to 25% of its assets in fixed income securities), the
SECURITIES                Portfolios of the Fund may invest temporarily in certain short-term
                          fixed income securities. Such securities may be used to invest
                          uncommitted cash balances, to maintain liquidity to meet shareholder
                          redemptions, or to take a temporarily defensive position against
                          potential stock market declines. These securities include: obligations
                          of the United States Government and its agencies or instrumentalities; 
                          commercial paper, bank certificates of deposit, and bankers' acceptances; 
                          and repurchase agreements collateralized by these securities.                                      
                          The use of repurchase agreements involves certain risks, including the   
                          risk of losses caused by the default or insolvency of the other party to 
                          the agreement. However,

                          each Portfolio expects that it can control this risk through 
                          careful evaluation of the creditworthiness of the other
                          party to any repurchase agreement and careful monitoring procedures.
EACH PORTFOLIO MAY        Each Portfolio may utilize stock futures contracts and options to a
USE FUTURES CONTRACTS     limited extent. Specifically, each Portfolio may enter into futures
AND OPTIONS               contracts provided that not more than 5% of its assets are required as a
                          futures contract deposit; in addition, each Portfolio may enter into
                          futures contracts and options transactions only to the extent that
                          obligations under such contracts or transactions represent not more than
                          20% of the Portfolio's assets.
                          Futures contracts and options may be used for several reasons: to
                          maintain cash reserves while simulating full investment, to facilitate
                          trading, to reduce transaction costs, or to seek higher investment
                          returns when a futures contract is priced more attractively than the
                          underlying equity security. While futures contracts and options can be
                          used as leveraged instruments, the Fund may not use futures contracts or
                          options to leverage its net assets.
                          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 leveraging involved in futures pricing. As a
                          result, a relatively small price movement in a futures contract may
                          result in immediate and substantial loss or gain. However, a Portfolio
                          will not use futures contracts or options for speculative purposes.
EACH PORTFOLIO MAY LEND   Each Portfolio may lend its securities on a short-term or long-term
  ITS SECURITIES          basis to qualified institutional investors for the purpose of realizing
                          additional income. With any loan of portfolio securities, there is a
                          risk that the borrowing institution will fail to redeliver the
                          securities when due. However, loans of securities by a 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.
EACH PORTFOLIO MAY        Each Portfolio may borrow money, subject to the limits set forth below,
BORROW MONEY              for temporary or emergency purposes, including the meeting of redemption
                          requests which might otherwise require the untimely disposition of
                          securities.
PORTFOLIO TURNOVER IS     Although they generally seek to invest for the long term, the Portfolios
NOT EXPECTED TO EXCEED    of the Fund retain the right to sell securities irrespective of how long
100%                      they have been held. It is anticipated that the annual portfolio
                          turnover of each Portfolio will not exceed 100%. A turnover rate of 100%
                          would occur, for example, if all the securities of a Portfolio were
                          replaced within one year.
- --------------------------------------------------------------------------------------------------
INVESTMENT                Each Portfolio has adopted certain limitations designed to reduce its
LIMITATIONS               exposure to specific situations. Some of these limitations are that a
THE FUND HAS ADOPTED      Portfolio will not:
                          (a) with respect to 75% of the value of its total assets, invest more
                              than 5% of its assets in the securities of any single company;                      
                          (b) with respect to 75% of the value of its total assets, purchase more  
                              than 10% of the voting securities of any issuer;

CERTAIN FUNDAMENTAL       (c) borrow money, except from banks (or through reverse repurchase
LIMITATIONS                   agreements) for temporary or emergency (not leveraging) purposes, and
                              then not in an amount exceeding 10% of the value of the Fund's net
                              assets at the time the borrowing is made. Whenever borrowing exceeds
                              5% of the value of the Fund's net assets, the Fund will not make any
                              additional investments;
                          (d) engage in the business of underwriting securities issued by other
                              persons, except to the extent that the Portfolio may technically be
                              deemed to be an underwriter under the Securities Act of 1993, as
                              amended, in disposing of investment securities;
                          (e) 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; and
                          (f) make loans except (i) by purchasing bonds, debentures or similar
                              obligations (including repurchase agreements, subject to the limitation
                              described in (e) above) which are either publicly distributed or
                              customarily purchased by institutional investors, and (ii) by
                              lending its securities to banks, brokers, 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 Commission thereunder and the aggregate value
                              of all securities loaned does not exceed 33 1/3% of the market value
                              of the Portfolio's 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 are fundamental and so may be
                          changed only with the approval of a majority of the Fund's shareholders.

MANAGEMENT OF             The Fund is a member of The Vanguard Group of Investment Companies, a
THE FUND                  family of 32 investment companies with 78 distinct investment portfolios
VANGUARD ADMINISTERS      and total assets in excess of $120 billion. Through their jointly owned
AND DISTRIBUTES THE       subsidiary, The Vanguard Group, Inc. ("Vanguard"), the Fund and the
FUND                      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 1993, 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 1.02% 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

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

                          WMC held discretionary management authority with respect to
                          approximately $82.8 billion of assets. WMC and its predecessor
                          organizations have provided investment advisory services to investment
                          companies since 1933 and to investment counseling clients since 1960.
                          Ernst H. von Metzsch, Senior Vice President of WMC, serves as the
                          portfolio manager of the Energy Portfolio. Edward P. Owens, Senior Vice
                          President of WMC, serves as portfolio manager of the Health Care

                          portfolio manager of the Utilities Income Portfolio. Mr. Ryan is
                          assisted by Paul D. Kaplan, Senior Vice President of WMC, who manages
                          the Portfolio's fixed income investments. Messrs. von Metzsch and Owens
                          have served as portfolio managers since the Fund's inception in May
                          1984; Messrs. Ryan and Kaplan have served as portfolio managers of the
                          Utilities Income Portfolio since its inception in May 1992. WMC's
                          portfolio managers are supported by research and other investment
                          services provided by the professional staff of WMC.
                          Under the investment advisory agreement, the three Portfolios are
                          required to pay WMC an aggregate fee at the end of the fiscal quarter,
                          calculated by applying the following annual percentage rates to the 
                          average month-end net assets for the quarter of the three Portfolios

                          In addition, once the advisory fee to WMC is calculated for the three
                          Portfolios under this schedule, the total fee will be reduced in order
                          that the advisory fee paid by the Utilities Income Portfolio does not
                          exceed 0.125%.
                          The advisory fee is based on the total assets for the three Portfolios
                          and is allocated, except as noted above, to each Portfolio based on the
                          net assets of each. For the fiscal year ended January 31, 1994, the
                          investment advisory fee represented an effective annual rate of .14 of
                          1% of average net assets for each Portfolio. This rate was payable under
                          the investment advisory agreement in effect prior to May 31, 1993.
M&G INVESTMENT            The Fund has also entered into an investment advisory agreement with M&G
MANAGEMENT LTD.           Investment Management Limited ("M&G"), Three Quays, Tower Hill, London
MANAGES THE GOLD &        EC3R 6BQ. Under that investment advisory agreement, M&G manages the
PRECIOUS METALS           investment and reinvestment of the assets of the Fund's Gold & Precious
PORTFOLIO                 Metals Portfolio and continuously reviews, supervises and administers
                          the Portfolio's investment program. M&G discharges its responsibilities
                          subject to the control of the Officers and Directors of the Fund.
                          M&G is a wholly-owned subsidiary of the M&G Group Plc and is authorized
                          to carry on investment business under English law by the Investment
                          Management Regulatory Organisation Limited. The M&G Group, an
                          independent group of companies, began providing investment advisory
                          services to the public over 50 years ago, when they launched Great
                          Britain's first unit trust (mutual fund). Today, the principal operating
                          subsidiaries of the M&G Group manage funds for some 146 accounts,
                          including individual investors, company pension plans and charitable
                          foundations. In total, the M&G Group manages or advises approximately
                          $20.5 billion in assets. Among these assets are two unit trusts that
                          invest in the securities of gold and precious metals related companies.
                          David J. Hutchins, an Investment Manager of M&G, serves as portfolio
                          manager of the Gold & Precious Metals Portfolio, a position he has held
                          since January, 1987.
                          Under the investment advisory agreement, the Gold & Precious Metals
                          Portfolio pays M&G a fee at the end of each fiscal quarter, calculated
                          by applying the following annual percentage rates to the average
                          month-end net assets of the Portfolio for the quarter:

                          The full range and quality of brokerage services are considered in
                          making these determinations.
                          The Fund has authorized WMC and M&G to pay higher commissions in
                          recognition of brokerage services felt necessary for the achievement of
                          better execution, provided the advisers believe this to be in the best
                          interest of the Fund. Although the Fund does not market its shares
                          through intermediary brokers or dealers, the Fund may place orders with
                          qualified broker-dealers who recommend the Fund to clients if the
                          Officers of the Fund believe that the quality of the transaction and the
                          commission are comparable to what they would be with other qualified
                          brokerage firms.
                          The Fund's Board of Directors may, without the approval of shareholders,
                          provide for: (a) the employment of a new investment adviser pursuant to
                          the terms of a new advisory agreement either as a replacement for an
                          existing adviser or as an additional adviser; (b) a change in the terms
                          of an advisory agreement; and (c) the continued employment of an
                          existing adviser on the same advisory contract terms where a contract
                          has been assigned because of a change in control of the adviser. Any
                          such change will only be made upon not less than 30 days prior written
                          notice to shareholders of the Fund which shall include substantially the
                          information concerning the adviser that would have normally been

DIVIDENDS,                The Utilities Income Portfolio pays dividends consisting of ordinary
CAPITAL GAINS             income on a quarterly basis; the Energy, Gold & Precious Metals, and
AND TAXES                 Health Care Portfolios pay dividends annually. Capital gains
THE UTILITIES INCOME      distributions, if any, are also made annually.
PORTFOLIO PAYS            Dividend and capital gains distributions may be automatically reinvested
DIVIDENDS QUARTERLY;      or received in cash. See "Choosing a Distribution Option" for a
THE OTHER PORTFOLIOS,     description of these distribution methods.
ANNUALLY                  In order to satisfy certain distribution requirements of the Tax Reform
                          Act of 1986, each Portfolio may declare 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.
                          Each Portfolio of the Fund 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 a
                          Portfolio from net investment income, whether received in cash or
                          reinvested in additional shares, will be taxable to shareholders as
                          ordinary income. For corporate investors, dividends from net investment
                          income will generally qualify in part for the intercorporate dividends-
                          received deduction. However, the portion of the dividends so qualified
                          depends on the aggregate taxable qualifying dividend income received by
                          the Portfolio from domestic (U.S.) sources.
                          Distributions paid by 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 byproduct 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 accept capital gains distributions in cash, instead of
                          reinvesting them in additional shares, you are in effect reducing the
                          capital at work for you in 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 a Portfolio.
THE GOLD & PRECIOUS       The Gold & Precious Metals Portfolio may elect to "pass through" to the

                          If this election is made, shareholders of the Gold & Precious Metals
                          Portfolio will be required to include in their gross income their pro
                          rata share of foreign taxes paid by the Portfolio. However, shareholders
                          will be able to treat their pro rata share of foreign taxes as either an
                          itemized deduction or a foreign tax credit against U.S. income taxes on
                          their tax return.
A CAPITAL GAIN OR LOSS    A sale of shares of a Portfolio of the Fund is a taxable event and may
MAY BE REALIZED           result in a capital gain or loss. A capital gain or loss may be realized

                          local taxes.
                          The Fund is required to withhold 31% of taxable dividends, capital gains
                          distributions, and redemptions paid to shareholders who have not
                          complied with IRS taxpayer identification regulations. You may avoid
                          this withholding requirement by certifying on your Account Registration

                          by certifying that you are not subject to backup withholding.
                          The Fund has obtained a Certificate of Authority to do business as a

THE SHARE PRICE OF        The share price or "net asset value" per share of each Portfolio is
EACH PORTFOLIO            computed once each day at the close of regular trading on the New York
                          Stock Exchange (generally 4:00 p.m. Eastern time) on each day the
                          Exchange is open for trading. Net asset value per share is computed by
                          dividing the total value of the investments and other assets of each
                          Portfolio, less any liabilities, by the total number of outstanding
                          shares of such Portfolio.
                          Securities listed on a U.S. exchange are valued at the latest quoted
                          sales prices on the day the valuation is made. Securities listed on a
                          U.S. exchange that are not traded on the valuation date are valued at
                          the mean of the bid and ask prices. Securities listed on a foreign
                          exchange are valued at the latest quoted sales price available before
                          the time when assets are valued. All prices of listed securities are
                          taken from the exchange where the security is primarily traded. Unlisted
                          securities for which market quotations are readily available are valued
                          at the latest quoted bid price. Other assets and securities for which no
                          market quotations are readily available are valued in good faith at fair
                          value using methods determined by, or under the supervision of, the
                          Board of Directors of the Fund. 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.
                          In determining each Portfolio's net asset value per share, all assets
                          and liabilities initially expressed in foreign currencies will be
                          converted into U.S. dollars at the bid price of such currencies against
                          U.S. dollars last quoted by a major bank or broker. If such quotations
                          are not available as of the close of the Exchange, the rate of exchange
                          will be determined in accordance with policies established in good faith
                          by the Board of Directors.

GENERAL                   The Fund is a Maryland corporation. The Articles of Incorporation permit
INFORMATION               the Directors to issue 6,000,000,000 shares of common stock, with a
                          $.001 par value. The Board of Directors has the power to designate one
                          or more classes ("Portfolios") of shares of common stock and to classify
                          or reclassify any unissued shares with respect to such classes.
                          Currently the Fund is offering four classes of shares.
                          The shares of each Portfolio are fully paid and non-assessable; have no
                          preference as to conversion, exchange, dividends, retirement or other
                          features; and have no 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 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%

                          determine which additional forms you may need. The Fund's shares are
                          purchased at the next-determined net asset value after your investment

                          Because of the risks associated with common stock and bond investments,
                          the Fund is intended to be a long-term investment vehicle and is not
                          designed to provide investors with a means of speculating on short-term
                          stock and 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.
IMPORTANT NOTE:           Potential investors should note that a 1% redemption fee is charged for
1% REDEMPTION FEE         the Energy, Gold & Precious Metals, and Health Care Portfolios. This
                          fee, which is paid to the Portfolios, applies to redemptions from these

CHOOSING A                You must select one of three distribution options:
DISTRIBUTION
OPTION                    1. AUTOMATIC REINVESTMENT OPTION -- Both dividends and capital gains
                             distributions will be reinvested in additional Fund shares. This option
                             will be selected for you automatically unless you specify one of the
                             other options.
                          2. CASH DIVIDEND OPTION -- Your dividends will be paid in cash and your
                             capital gains will be reinvested in additional Fund shares.
                          3. ALL CASH OPTION -- Both dividend and capital gains distributions will
                             be paid in cash.
                          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 see "Other Vanguard Services"
                          for more information.
- --------------------------------------------------------------------------------------------------
TAX CAUTION               Under Federal tax laws, the Fund is required to distribute net capital
INVESTORS SHOULD ASK      gains and dividend income to Fund shareholders. These distributions are
ABOUT THE TIMING OF       made to all shareholders who own Fund shares as of the distribution's
CAPITAL GAINS AND         record date, regardless of how long the shares have been owned.
DIVIDEND DISTRIBUTIONS    Purchasing shares just prior to the record date could have a significant
BEFORE INVESTING          impact on your tax liability for the year. For example, if you purchase
                          shares immediately prior to the record date of a sizable capital gain or
                          income dividend distribution, you will be assessed taxes on the amount
                          of the capital gain and/or dividend distribution later paid even though
                          you owned the Fund shares for just a short period of time. (Taxes are
                          due on the distributions even if the dividend or gain is reinvested in
                          additional Fund shares.) While the total value of your investment will
                          be the same after the distribution--the amount of the distribution will
                          offset the drop in the net asset value of the shares--you should be
                          aware of the tax implications the timing of your purchase may have.
                          Prospective investors should, therefore, inquire about potential
                          distributions before investing. The Fund's annual capital gains
                          distribution normally occurs in December, while income dividends are
                          generally paid quarterly in March, June, September and December for the
                          Utilities Income Portfolio and annually in December for the Energy,
                          Gold & Precious Metals, and Health Care Portfolios. For additional
                          information on distributions and taxes, see the section titled
                          "Dividends, Capital Gains, and Taxes."

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

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

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

                          telephoning. Your redemption proceeds are normally mailed within two
                          business days after the receipt of the request in Good Order.
                          IMPORTANT NOTE: For investors in the Energy, Gold & Precious Metals, and
                          Health Care Portfolios, a redemption fee amounting to 1% of the value of
                          the shares redeemed will be deducted from the redemption proceeds if
                          shares held for less than one year are redeemed. This fee is paid

                          The Fund may suspend the redemption right or postpone payment at times
                          when the New York Stock Exchange is closed or under any emergency

                          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

VANGUARD'S AVERAGE        If you make a redemption from a qualifying account, Vanguard will send
COST STATEMENT            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           Due to the relatively high cost of maintaining smaller accounts, the
BALANCE                   Fund reserves the right to redeem shares in any account that is below
REQUIREMENT               the minimum initial investment amount of $3,000. In addition, if at any
                          time your total investment in a Portfolio does not have a value of at
                          least $1,000, you may be notified that the value of 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 shareholder. This
                          minimum requirement does not apply to IRAs, other retirement accounts
                          and Uniform Gifts/Transfers to Minors Act accounts.

IMPORTANT EXCHANGE        Before you make an exchange, you should consider the following:
INFORMATION               - Please read the Fund's prospectus before making an exchange. For a
                            copy and for answers to any questions you may have, call our Investor
                            Information Department (1-800-662-7447).
                          - An exchange is treated as a redemption and a purchase. Therefore, you
                            could realize a taxable gain or loss on the transaction.
                          - Exchanges are accepted only if the registrations and the Taxpayer
                            Identification numbers of the two accounts are identical.
                          - The shares to be exchanged must be on deposit and not held in
                            certificate form.
                          - New accounts are not currently accepted in Vanguard/Windsor Fund.
                          - The redemption price of shares redeemed by exchange is the net asset
                            value next determined after Vanguard has received the required 
                            documentation in Good Order.
                          - When opening a new account by exchange, you must meet the minimum
                            investment requirement of the new Fund.
                          Every effort will be made to maintain the exchange privilege. However,
                          the Fund reserves the right to revise or terminate its provisions, limit
                          the amount of or reject any exchange, as deemed necessary, at any time.
- --------------------------------------------------------------------------------------------------
EXCHANGE                  The Fund's exchange privilege is not intended to afford shareholders a
PRIVILEGE                 way to speculate on short-term movements in the market. Accordingly, in
LIMITATIONS               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
                          THREE 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                 The ability to initiate redemptions (except wire redemptions) and

TRANSACTIONS              account not be permitted.
                          To protect your account from losses resulting from unauthorized or
                          fraudulent telephone instructions, Vanguard adheres to the following
                          security procedures:

<S>                       <C>
                          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 in which the account is registered; and
                             (iv) the Social Security or Taxpayer 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. If Vanguard fails to follow reasonable security procedures, it
                          may be liable for any losses resulting from unauthorized or fraudulent
                          telephone transactions on your account.

INVESTMENT                 Vanguard Specialized Portfolios, Inc. (the "Fund") is an open-end
OBJECTIVES                 diversified investment company which consists of four Portfolios. This
AND POLICIES               prospectus relates only to the Utilities Income Portfolio (the
                           "Portfolio"). The objective of the Portfolio is to provide current income
                           and growth of capital and income. The Portfolio invests primarily in common

                           Portfolio will achieve its stated objective. Given its specialized focus,
                           the Portfolio should not be considered a complete investment program.

YIELD AND TOTAL           From time to time the Portfolio may advertise its yield and total
RETURN                    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.
                          The "30-day yield" of the Portfolio is calculated by dividing net
                          investment income per share earned during a 30-day period by the net
                          asset value per share on the last day of the period. Net investment
                          income includes interest and dividend income earned on the Portfolio's
                          securities; 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 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 or the yield reported in the Portfolio's financial statements.

                          Also, the Portfolio may compare its performance to that of various stock
                          market indices, including the Standard & Poor's 500 Index and the
                          Standard & Poor's Utility Index.
- --------------------------------------------------------------------------------------------------
INVESTMENT                The objective of the Portfolio is to provide current income and growth
OBJECTIVE                 of capital and income. There can be no assurance that the Portfolio will
THE PORTFOLIO SEEKS       achieve its stated objective. The Portfolio is one of four Portfolios of
CURRENT INCOME            Vanguard Specialized Portfolios, Inc. (the "Fund").
                          The investment objective of the Portfolio is fundamental and so cannot
                          be changed without the approval of a majority of the Portfolio's
                          shareholders.
- --------------------------------------------------------------------------------------------------
INVESTMENT                Under normal circumstances, the Portfolio will invest at least 75% of
POLICIES                  its assets in equity securities of companies in the utilities industry.
THE PORTFOLIO INVESTS     The remainder of the Portfolio's assets will be invested in utility
IN UTILITY STOCKS AND     bonds rated A or better by Standard & Poor's Corporation or Moody's
BONDS                     Investors Service. Because of its emphasis on higher-yielding utility
                          stocks and its holdings of utility bonds, the Portfolio is expected to
                          offer a dividend yield well above the stock market average. The
                          Portfolio is managed without regard to tax ramifications.
                          The Portfolio will invest primarily in securities that trade in U.S.
                          markets. The Portfolio may invest up to 20% of its assets in foreign
                          securities, but has no present intention of investing more than 10% of
                          its assets in such securities. In order to protect against fluctuations
                          in foreign exchange rates, the Portfolio may invest in forward foreign
                          currency exchange contracts.
                          Besides investing primarily in equity securities, the Portfolio may hold
                          certain short-term fixed income securities as cash reserves. The
                          Portfolio may also invest in stock futures contracts and options to a
                          limited extent. See "Implementation of Policies" for a description of
                          these and other investment practices of the Fund.
                          The investment policies of the Portfolio are not fundamental and so may
                          be changed by the Board of Directors without shareholder approval.
- --------------------------------------------------------------------------------------------------
INVESTMENT RISKS          As a mutual fund specializing in utility stocks and bonds, the Portfolio
                          is subject primarily to four types of risk: stock market risk, interest
                          rate risk, industry risk, and manager risk. Since the Portfolio may
                          invest in foreign securities, investors are also exposed to currency
                          risk and other risks of international investing.
MARKET RISK MAY BE        Market risk is the possibility that stock prices in general will decline
SUBSTANTIAL               over short or even extended periods. The stock market tends to be
                          cyclical, with periods when stock prices generally rise and periods when
                          stock prices generally decline. In the period from 1926 to 1993, stocks
                          have provided an average annual total return (capital appreciation plus
                          dividend income) of +12.3%, as measured by the Standard & Poor's 500
                          Composite Stock Price Index. In contrast, the return on stocks in
                          individual years has varied from a low of -43.3% to a high of +53.9%,
                          reflecting the short-term volatility of stock prices.

                          However, the Portfolio is expected to exhibit somewhat less volatility
                          than the stock market as a whole. Historically, utility stocks have been
                          one of the least volatile sectors of the stock market (when measured by
                          such statistics as standard deviation of returns or industry "beta").
                          Moreover, the Portfolio's investment in utility bonds is expected to
                          further dampen the stock market's influence on the Portfolio.
INTEREST RATE RISK MAY    In addition to stock market risk, utility stocks and bonds are also
BE SUBSTANTIAL            subject to interest rate risk--price fluctuations due to changing market
                          interest rates. In general, fixed income investments, such as bonds,
                          vary inversely with interest rates, falling in price when interest rates
                          rise, and rising in price when interest rates fall. Utility stocks, more
                          so than other stock market sectors, are often influenced by these trends
                          in interest rates, rather than price movements in the stock market. At
                          the same time, the Portfolio's bond holdings are subject to interest
                          rate risk. This combination of interest-rate-sensitive stocks and bonds
                          means that the Portfolio may at times move in tandem with the bond
                          market, rising and falling as interest rates change, independent of the
                          stock market.
INVESTORS ARE EXPOSED     In addition to stock market and interest rate risk, the Portfolio is
TO INDUSTRY RISK          subject to industry risk--i.e., the possibility that a particular group
                          of related stocks will decline in price due to industry-specific
                          developments.
                          Changing regulation constitutes one of the key industry specific risks
                          for the Portfolio. Regulators (largely at the state level) monitor and
                          control utility revenues and costs, and therefore may limit utility
                          profits and dividends paid to investors. Regulatory authorities may also
                          restrict a company's access to new markets, thereby diminishing the
                          firm's long-term prospects. Individual sectors of the utility market are
                          subject to the following additional risks:
                          - Electric utilities may be burdened by unexpected increases in fuel and
                            other operating costs. They are also adversely affected when long-term
                            interest rates rise. Long-term borrowings are used to finance most
                            utility investment, and rising interest rates lead to higher financing
                            costs and reduced earnings. There are also the considerable costs
                            associated with environmental compliance, nuclear waste clean-up, and
                            safety regulation. Increasingly, electric utilities are being called
                            upon by regulators to bear these added costs, and there is a risk that
                            these costs will not be fully recovered through an increase in
                            revenues.
                          - Telephone utilities have been buffeted by technological development
                            leading to increased competition, as well as changing regulation of
                            long-distance telephone service and other telecommunications
                            businesses. While certain companies have benefitted from the new
                            competitive climate, others have not, and increased competition in the
                            future may hinder the growth of more traditionally oriented telephone
                            companies.
                          - Among gas transmission and distribution companies, there has been a
                            move to diversify into oil and gas exploration and development, making
                            investment returns more sensitive to energy prices. In the case of the
                            water utility sector, the industry is highly fragmented, and most
                            water supply companies find themselves in mature markets, with little
                            potential for growth.

THE PORTFOLIO IS          In addition to the risks described above, the Portfolio is subject to
SUBJECT TO MANAGER        manager risk. The investment adviser manages the Portfolio according to
RISK                      the traditional methods of "active" investment management, which
                          involves the buying and selling of securities based upon economic,
                          financial and market analysis and investment judgment. Manager risk
                          refers to the possibility that the Portfolio's investment adviser may
                          fail to execute the Portfolio's investment strategy effectively. As a
                          result, the Portfolio may fail to achieve its stated objective.
FOREIGN SECURITIES        Since the Portfolio may invest in foreign securities, investors are also
ENTAIL CURRENCY AND       exposed to the unique risks of international investing. For U.S.
OTHER RISKS               investors, the returns of foreign securities are influenced by not only
                          the returns on foreign common stocks themselves, but also by currency
                          risk--i.e., changes in the value of the currencies in which the stocks
                          are denominated. In a period when the U.S. dollar rises against foreign
                          currencies, the returns on foreign stocks for a U.S. investor are
                          diminished. By contrast, in a period when the U.S. dollar declines, the
                          returns on foreign stocks are enhanced.
                          Other risks and considerations of international investing include the
                          following: differences in accounting, auditing and financial reporting
                          standards; generally higher commission rates on foreign portfolio
                          transactions; the smaller trading volumes and generally lower liquidity
                          of foreign stock markets, which may result in greater price volatility;
                          foreign withholding taxes payable on a Portfolio's foreign securities,
                          which may reduce dividend income payable to shareholders; the
                          possibility of expropriation or confiscatory taxation; adverse changes
                          in investment or exchange control regulations; political instability
                          which could affect U.S. investment in foreign countries; difficulty in
                          obtaining and enforcing foreign court judgments; and potential
                          restrictions on the flow of international capital.
HIGHER YIELDS AND         Investors in the Portfolio should be aware that while utility stocks
RETURNS MAY NOT           have historically provided above-average dividend yields, there is no
PERSIST                   guarantee that they will continue to do so in the future. For example,
                          as of January 31, 1994, the Standard & Poor's Utility Index provided a
                          current yield of 5.1%, which was nearly two times as high as the yield
                          of 2.6% provided by the broad stock market (as measured by the Standard
                          & Poor's 500 Index). Many of the risks enumerated above have made it
                          increasingly difficult for utility companies to sustain such generous
                          dividend pay-outs, and future dividend yields of the utility sector
                          could decline.
                          Similarly, while utility stocks during recent years have provided total
                          investment returns (dividend yield plus capital change) above stock
                          market averages, there is again no guarantee that such returns will
                          continue. For example, during the ten-year period ended January 31,
                          1994, the Standard & Poor's Utility Index gained 17.1% per year on
                          average, while the Standard & Poor's 500 Index, a measure of the broad
                          stock market, returned 15.3% per year. Investors should recognize that a
                          period of above-average investment performance by a stock market sector,
                          such as that provided by utility stocks over the past ten years, is
                          often followed by a period of below-average investment performance. In

                          anticipate that utility stocks will outperform the broad stock market
                          over the long haul, given the generally limited growth prospects of the
                          utilities industry.
- --------------------------------------------------------------------------------------------------
WHO SHOULD                The Utilities Income Portfolio is designed for investors who are seeking
INVEST                    a more conservative, income-oriented stock market investment. The
INVESTORS SEEKING AN      Portfolio is likely to offer higher dividend yields than the stock
INCOME-ORIENTED STOCK     market average, with substantially lower volatility in share price. The
INVESTMENT                Portfolio may also offer modest growth in income and capital over time.
                          Nonetheless, because utility stock and bond prices will fluctuate,
                          sometimes substantially, investors should be willing to accept moderate
                          to high fluctuations in principal value. Because of the risks associated
                          with common stock and bond 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 common stock and bond market
                          movements. Investors who engage in excessive account activity generate
                          additional costs which are borne by all of the Portfolio shareholders.
                          In order to minimize such costs the Portfolio has adopted the following
                          policies. The Portfolio reserves the right to reject any purchase
                          request (including exchange purchases from other Vanguard portfolios)
                          that is reasonably deemed to be disruptive to efficient portfolio
                          management, either because of the timing of the investment or previous
                          excessive trading by the investor. Additionally, the Portfolio has
                          adopted exchange privilege limitations as described in the section
                          "Exchange Privilege Limitations." Finally, the Portfolio reserves the
                          right to suspend the offering of its shares.
                          There can be no assurance that the Portfolio will achieve its stated
                          objective, or that shareholders will be protected from the substantial
                          risks inherent in equity investing. Investors may wish to reduce the
                          potential risk of investing in the Portfolio by purchasing shares on a
                          periodic basis (dollar cost averaging) rather than investing in one lump
                          sum.
                          Since the Portfolio concentrates its holdings in equity securities of
                          companies in the utilities industry, the Portfolio should not be considered
                          a complete investment program. Most investors should maintain diversified 
                          holdings of securities with different risk characteristics--including common 
                          stocks, bonds and money market instruments.
- --------------------------------------------------------------------------------------------------
IMPLEMENTATION OF         The Portfolio follows a number of investment practices in an effort to
POLICIES                  achieve its objective of long-term capital growth.
THE PORTFOLIO INVESTS     The Portfolio invests in equity and debt securities of companies engaged
IN A RANGE OF UTILITY     in the generation, transmission, or distribution of electricity,
STOCKS AND BONDS          telecommunications, gas, or water. Such investments will be selected on
                          the basis of fundamental analysis to identify those securities that the
                          adviser believes will provide both current income and the potential for
                          growth in income and capital over time.
                          The utilities sector of the stock market, from which the Portfolio's
                          primary investments will be drawn, is dominated by telephone and
                          electric utility common stocks, with gas and water companies playing an
                          appreciably smaller role. For

                          Similarly, the market for utility bonds is dominated by telephone and
                          electric utility issuers. For example, as of March 31, 1994, telephone
                          company bonds represented 33% of the outstanding utility bonds rated A
                          or better (measured in terms of market value by the Lehman Brothers
                          Investment Grade Utility Bond Index). Electric utility issues accounted
                          for 35% of A-or-better utility bonds, while gas, water and other
                          utilities represented the remaining 32%.
                          Utilities are subject to strict regulatory oversight. However, in recent
                          years, changes in the regulatory climate have allowed utilities to
                          provide products and services outside their traditional geographic
                          areas, leading to increased competition and expanded prospects for
                          growth. The Portfolio seeks to take advantage of favorable opportunities
                          that are expected to arise from these structural changes in regulation.
THE PORTFOLIO MAY         The Portfolio may invest up to 20% of its assets in foreign securities,
HOLD FOREIGN              but at present is not expected to invest more than 10% of its net assets
SECURITIES                in foreign securities. Such a policy expands the investment
                          opportunities available to the Portfolio and may result in improved
                          diversification and performance.
                          All or a portion of the foreign securities purchased by the Portfolio
                          may be in the form of American Depository Receipts (ADRs) or European
                          Depository Receipts (EDRs). ADRs are receipts typically issued by a U.S.
                          bank or trust company that evidence ownership of underlying securities
                          issued by a foreign corporation. EDRs are receipts issued in Europe that
                          evidence a similar ownership arrangement. Generally, ADRs are designed
                          for trading in the United States securities markets and EDRs are
                          designed for trading in European securities markets.
THE PORTFOLIO MAY         The Portfolio may enter into forward foreign currency exchange contracts
ENTER INTO FORWARD        in order to protect against uncertainty in the level of future foreign
CURRENCY CONTRACTS        exchange rates in the purchase and sale of investment securities. The
                          Portfolio may not enter into such contracts for speculative purposes.
                          A forward foreign currency exchange contract is an obligation to
                          purchase or sell a specific currency at a future date, which may be any
                          fixed number of days from the date of the contract agreed upon by the
                          parties, at a price set at the time of the contract. These contracts may
                          be bought or sold to protect the Portfolio to a limited extent against
                          adverse changes in exchange rates between foreign currencies and the
                          U.S. dollar. Such contracts, which protect the value of the Portfolio's
                          investment securities against a decline in the value of a currency, do
                          not eliminate fluctuations in the underlying prices of the securities.
                          They simply establish an exchange rate at

                          a future date. Also, although such contracts tend to minimize the risk of
                          loss due to a decline in the value of the hedged currency, at the same 
                          time they tend to limit any potential gain that might be realized should 
                          the value of such currency increase.
THE PORTFOLIO MAY         The Portfolio may invest temporarily in certain short-term fixed income
INVEST IN SHORT-TERM      securities. Such securities may be used to invest uncommitted cash
FIXED INCOME              balances, to maintain liquidity to meet shareholder redemptions, or to
SECURITIES                take a temporarily defensive position against potential stock market
                          declines. These securities include: obligations of the United States
                          Government and its agencies or instrumentalities; commercial paper, bank
                          certificates of deposit, and bankers' acceptances; and repurchase
                          agreements collateralized by these securities.
                          The use of repurchase agreements involves certain risks, including the
                          risk of losses caused by the default or insolvency of the other party to
                          the agreement. However, the Portfolio expects that it can control this
                          risk through careful evaluation of the creditworthiness of the other
                          party to any repurchase agreement and careful monitoring procedures.
THE PORTFOLIO MAY USE     The Portfolio may utilize stock futures contracts and options to a
FUTURES CONTRACTS AND     limited extent. Specifically, the Portfolio may enter into futures
OPTIONS                   contracts provided that not more than 5% of its assets are required as a
                          futures contract deposit; in addition, the Portfolio may enter into
                          futures contracts and options transactions only to the extent that
                          obligations under such contracts or transactions represent not more than
                          20% of the Portfolio's assets.
                          Futures contracts and options may be used for several reasons: to
                          maintain cash reserves while simulating full investment, to facilitate
                          trading, to reduce transaction costs, or to seek higher investment
                          returns when a futures contract is priced more attractively than the
                          underlying equity security. While futures contracts and options can be
                          used as leveraged instruments, the Portfolio may not use futures
                          contracts or options to leverage its net assets.
                          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 leveraging involved in futures pricing. As a
                          result, a relatively small price movement in a futures contract may
                          result in immediate and substantial loss or gain. However, the Portfolio
                          will not use futures contracts or options for speculative purposes.
THE PORTFOLIO MAY         The Portfolio may lend its investment securities on a short-term or
LEND ITS SECURITIES       long-term basis to qualified institutional investors for the purpose of
                          realizing additional income. A loan of portfolio securities may be
                          either short-term (less than nine months) or long-term. With any loan of
                          portfolio securities, there is a risk that the borrowing institution
                          will fail to redeliver the securities when due. However, 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.

THE PORTFOLIO MAY         The Portfolio may borrow money, subject to the limits set forth below,
BORROW MONEY              for temporary or emergency purposes, including the meeting of redemption
                          requests which might otherwise require the untimely disposition of
                          securities.
PORTFOLIO TURNOVER IS     Although it generally seeks to invest for the long term, the Portfolio
NOT EXPECTED TO           retains the right to sell securities irrespective of how long they have
EXCEED 100%               been held. It is anticipated that the annual portfolio turnover of the
                          Portfolio will not exceed 100%. A turnover rate of 100% would occur, for
                          example, if all of the securities held by the Portfolio were replaced
                          within one year.

INVESTMENT                The Portfolio has adopted certain limitations designed to reduce its
LIMITATIONS               exposure to specific situations. Some of these limitations are that the
THE FUND HAS ADOPTED      Portfolio will not:
CERTAIN FUNDAMENTAL
LIMITATIONS               (a) with respect to 75% of the value of its total assets, invest more
                              than 5% of its assets in the securities of any single company;
                          (b) with respect to 75% of the value of its total assets, purchase more
                              than 10% of the voting securities of any issuer;
                          (c) borrow money, except from banks (or through reverse repurchase
                              agreements) for temporary or emergency (not leveraging) purposes, and
                              then not in an amount exceeding 10% of the value of the Fund's net
                              assets at the time the borrowing is made. Whenever borrowing exceeds
                              5% of the value of the Fund's net assets, the Fund will not make any
                              additional investments;
                          (d) engage in the business of underwriting securities issued by other
                              persons, except to the extent that the Portfolio may technically be
                              deemed to be an underwriter under the Securities Act of 1933, as
                              amended, in disposing of investment securities;
                          (e) 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; and
                          (f) make loans except (i) by purchasing bonds, debentures or similar
                              obligations (including repurchase agreements, subject to the limitation
                              described in (e) above) which are either publicly distributed or
                              customarily purchased by institutional investors, and (ii) by
                              lending its securities to banks, brokers, 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 Commission thereunder and the aggregate
                              value of all securities loaned does not exceed 33 1/3% of the
                              market value of the Portfolio's 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 are fundamental and so may be
                          changed only with the approval of a majority of the Portfolio's
                          shareholders.

MANAGEMENT OF             The Portfolio is one of four Portfolio's of Vanguard Specialized
THE PORTFOLIO             Portfolios, Inc. (the "Fund"), a member of The Vanguard Group of
VANGUARD ADMINISTERS      Investment Companies, a family of 32 investment companies with 78
AND DISTRIBUTES THE       distinct investment portfolios and total assets in excess of $120
PORTFOLIO                 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 1993,
                          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 1.02% for the mutual fund industry (data
                          provided by Lipper Analytical Services).
                          The Officers of the Portfolio manage the day to day operations of the
                          Portfolio 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 needed to provide the requisite services to the funds and also
                          furnishes the funds with necessary office space, furnishings and
                          equipment. Each fund pays its share of Vanguard's net expenses, which
                          are allocated among the funds under methods approved by the Board of
                          Directors (Trustees) of each fund. In addition, each fund bears its own
                          direct expenses, such as legal, auditing and custodian fees.
                          Vanguard provides distribution and marketing services to the funds. The
                          funds are available on a no-load basis (i.e., there are no sales
                          commissions or 12b-1 fees). However, each fund bears its share of the
                          Group's distribution costs.

PORTFOLIO                 WMC is a professional investment advisory firm which globally provides
                          services to investment companies, institutions and individuals. Among
                          the clients of WMC are 12 of the 32 investment companies of The Vanguard
                          Group. As of December 31, 1993, WMC held discretionary management
                          authority with respect to approximately $82.8 billion of assets. WMC and
                          its predecessor organizations have provided advisory services to

                          since 1960.
                          John R. Ryan, Senior Vice President of WMC, serves as the portfolio

                          Messrs. Ryan and Kaplan have served as porfolio managers of the Utilities
                          Income Portfolio since its inception in May 1992.  WMC's portfolio managers
                          are supported by research and other investment services provided by the
                          professional staff of WMC.
                          Under the Fund's investment advisory agreement, the fee paid to WMC is
                          based on the total assets of the Utilities Income Portfolio and the
                          total assets of two other Portfolios of Vanguard Specialized Portfolios,
                          Inc. managed by WMC (Energy and Health Care Portfolios). The three
                          Portfolios are required to pay WMC an aggregate fee at the end of the
                          fiscal quarter, calculated by applying the following annual percentage
                          rates to the average month-end net assets for the quarter of the
                          three Portfolios:

                          In addition, once the advisory fee to WMC is calculated for the three
                          Portfolios under this schedule, the total fee will be reduced in order
                          that the advisory fee paid by the Utilities Income Portfolio does not
                          exceed 0.125%.
                          The advisory fee is based on the total assets for the three Portfolios
                          and is allocated, except as noted above, to each Portfolio based on the
                          net assets of each. For the fiscal year ended January 31, 1994, the
                          investment advisory fee represented an effective annual rate of .13 of 
                          1% of average net assets for each Portfolio. This rate was payable under 
                          the investment advisory agreement in effect prior to May 31, 1993.
                          The investment advisory agreement with WMC authorizes the adviser to
                          select brokers or dealers to execute purchases and sales of the
                          Portfolio's securities, and direct the advisers to use their best
                          efforts to obtain the best available price and most favorable execution
                          with respect to all transactions. The full range and quality of
                          brokerage services are considered in making these determinations.
                          The Portfolio has authorized WMC to pay higher commissions in
                          recognition of brokerage services felt necessary for the achievement of
                          better execution, provided the adviser believes this to be in the best
                          interest of the Portfolio. Although the Portfolio does not market its
                          shares through intermediary brokers or dealers, the Portfolio may place
                          orders with qualified broker-dealers who recommend the Portfolio to
                          clients if the Officers of the Fund believe that the quality of the
                          transaction and the commission are comparable to what they would be with
                          other qualified brokerage firms.
                          The Portfolio's Board of Directors may, without the approval of
                          shareholders, provide for: (a) the employment of a new investment
                          adviser pursuant to the terms of a new advisory agreement either as a

                          control of the adviser. Any such change will only be made upon not less
                          than 30 days prior written notice to shareholders of the Portfolio which
                          shall include substantially the information concerning the adviser that

DIVIDENDS,                The Utilities Income Portfolio pays dividends consisting of ordinary
CAPITAL GAINS             income on a quarterly basis. Capital gains distributions, if any, are
AND TAXES                 made annually.
THE UTILITIES INCOME      Dividend and capital gains distributions may be automatically reinvested
PORTFOLIO PAYS            or received in cash. See "Choosing a Distribution Option" for a
QUARTERLY DIVIDENDS       description of these distribution methods.
                          In order to satisfy certain distribution requirements of the Tax Reform
                          Act of 1986, the Portfolio may declare year-end dividend and capital
                          gains distributions during December. Such distributions, if received by
                          shareholders by January 31, are deemed to have been paid by the
                          Portfolio and received by shareholders on December 31 of the prior year.
                          The Portfolio intends to continue to qualify for taxation as a
                          "regulated investment company" under the Internal Revenue Code so that
                          the Portfolio will not be subject to federal income tax to the extent
                          its income is distributed to shareholders. Dividends paid by the
                          Portfolio from net investment income, whether received in cash or
                          reinvested in additional shares, will be taxable to shareholders as
                          ordinary income. For corporate investors, dividends from net investment
                          income will generally qualify in part for the intercorporate
                          dividends-received deduction. However, the portion of the dividends so
                          qualified depends on the aggregate taxable qualifying dividend income
                          received by the Portfolio from domestic (U.S.) sources.
                          Distributions paid by the Portfolio from long-term capital gains,
                          whether received in cash or reinvested in additional shares, are taxable
                          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 byproduct 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 accept capital gains distributions in cash, instead of
                          reinvesting them in additional shares, you are in effect reducing the
                          capital at work for you in the 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 Portfolio will notify you annually as to the tax status of dividend
                          and capital gains distributions paid by the Portfolio.

                          The Fund is required to withhold 31% of taxable dividends, capital gains
                          distributions, and redemptions paid to shareholders who have not
                          complied with IRS taxpayer identification regulations. You may avoid
                          this withholding requirement by certifying on your Account Registration 
                          Form your proper Social Security or Taxpayer Identification Number and by 
                          certifying that you are not subject to backup withholding.
                          The Portfolio has obtained a Certificate of Authority to do business as
                          a foreign corporation in Pennsylvania and does business and maintains an
                          office in that state. In the opinion of counsel, the shares of the
                          Portfolio are exempt from Pennsylvania personal property taxes.
                          The tax discussion set forth above is included for general information
                          only. Prospective investors should consult their own tax advisers

THE SHARE PRICE           The share price or "net asset value" per share of the Portfolio is
OF THE PORTFOLIO          computed once each day at the close of regular trading on the New York
                          Stock Exchange (generally 4:00 p.m. Eastern time) on each day the
                          Exchange is open for trading. Net asset value per share is computed by
                          dividing the total value of the investments and other assets of the
                          Portfolio, less any liabilities, by the total number of outstanding
                          shares of the Portfolio.  
                          Securities listed on a U.S. exchange are valued at the latest quoted
                          sales prices on the day the valuation is made. Securities listed on a
                          U.S. exchange that are not traded on the valuation date are valued at
                          the mean of the bid and ask prices. Securities listed on a foreign
                          exchange are valued at the latest quoted sales price available before
                          the time when assets are valued. All prices of listed securities are
                          taken from the exchange where the security is primarily traded. Unlisted
                          securities for which market quotations are readily available are valued
                          at the latest quoted bid price. Other assets and securities for which no
                          market quotations are readily available are valued in good faith at fair
                          value using methods determined by, or under the supervision of, the
                          Board of Directors of the Fund. 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.
                          In determining the Portfolio's net asset value per share, all assets and
                          liabilities initially expressed in foreign currencies will be converted

GENERAL                   The Portfolio is one of four Portfolios of Vanguard Specialized
INFORMATION               Portfolios, Inc. (the "Fund"). The Fund is a Maryland corporation. The
                          Articles of Incorporation permit the Directors to issue 6,000,000,000
                          shares of common stock, with a $.001 par value. The Board of Directors
                          has the power to designate one or more classes ("Portfolios") of shares
                          of common stock and to classify or reclassify any unissued shares with
                          respect to such classes. Currently the Fund is offering four classes
                          of shares.
                          The shares of each Portfolio are fully paid and non-assessable; have no
                          preference as to conversion, exchange, dividends, retirement or other
                          features; and have no 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 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 for the Utilities Income Portfolio are held by
                          State Street Bank and Trust Company, Boston, MA. The Vanguard Group,
                          Inc., Valley Forge, PA, serves as the Fund's Transfer and Dividend
                          Disbursing Agent. Price Waterhouse serves as independent accountants for
                          the Fund and will audit its financial statements annually. The Fund is
                          not involved in any material litigation.

SHARES                    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

                          generally limited to the amount withdrawn within the past 60 days from
                          an IRA or other qualified Retirement Plan. If you need assistance with
                          the forms or have any questions about the Portfolio, please call our
                          Investor Information Department (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 and bond 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 and bond 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.
                          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                Subsequent investments to regular accounts may be made by mail ($100
INVESTMENTS               minimum), wire ($1,000 minimum), 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.

DISTRIBUTION
OPTION                    1. AUTOMATIC REINVESTMENT OPTION -- Both dividends and capital gains
                             distributions will be reinvested in additional Fund shares. This option
                             will be selected for you automatically unless you specify one of the
                             other options.
                          2. CASH DIVIDEND OPTION -- Your dividends will be paid in cash and your
                             capital gains will be reinvested in additional Fund shares.
                          3. ALL CASH OPTION -- Both dividend and capital gains distributions will
                             be paid in cash.
                          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 see "Other Vanguard Services"
                          for more information.
- --------------------------------------------------------------------------------------------------
TAX CAUTION               Under Federal tax laws, the Portfolio is required to distribute net
INVESTORS SHOULD ASK      capital gains and dividend income to Portfolio shareholders. These
ABOUT THE TIMING OF       distributions are made to all shareholders who own Portfolio shares as
CAPITAL GAINS AND         of the distribution's record date, regardless of how long the shares
DIVIDEND DISTRIBUTIONS    have been owned. Purchasing shares just prior to the record date could
BEFORE INVESTING          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 capital gains
                          distribution normally occurs in December, while income dividends are
                          generally paid quarterly in March, June, September and December. For
                          additional information on distributions and taxes, see the section
                          titled "Dividends, Capital Gains, and Taxes."

CANCELLING TRADES         The Fund will not cancel any trade (e.g., a purchase, exchange or

                          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.

MINIMUM ACCOUNT           Due to the relatively high cost of maintaining smaller accounts, the
BALANCE REQUIREMENT       Fund reserves the right to redeem shares in any account that is below
                          the minimum initial investment amount of $3,000. In addition, if at any
                          time your total investment in the Portfolio does not have a value of at
                          least $1,000, you may be notified that the value of 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 shareholder. This
                          minimum requirement does not apply to IRAs, other retirement accounts

<S>                       <C>
                          - 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 of the two accounts
                            are identical.
                          - The shares to be exchanged must be on deposit and not held in
                            certificate form.
                          - New accounts are not currently accepted in Vanguard/Windsor Fund.
                          - The redemption price of shares redeemed by exchange is the net asset
                            value next determined after Vanguard has received the required
                            documentation in Good Order.
                          - When opening a new account by exchange, you must meet the minimum
                            investment requirement of the new Fund.
                          Every effort will be made to maintain the exchange privilege. However,
                          the Fund reserves the right to revise or terminate its provisions, limit
                          the amount of or reject any exchange, as deemed necessary, at any time.
- --------------------------------------------------------------------------------------------------
EXCHANGE                  The Fund's exchange privilege is not intended to afford shareholders a
PRIVILEGE                 way to speculate on short-term movements in the market. Accordingly, in
LIMITATIONS               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
                          THREE 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                 The ability to initiate redemptions (except wire redemptions) and
INFORMATION               exchanges by telephone is automatically established on your account
ABOUT TELEPHONE           unless you request in writing that telephone transactions on your
TRANSACTIONS              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 in which the account is registered; and
                             (iv) the Social Security or Taxpayer 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 Portfolio nor Vanguard will be responsible for the
                          authenticity of transaction instructions received by telephone, provided
                          that reasonable security procedures have been followed. Vanguard
                          believes that the security procedures

                          you will bear the risk of any losses resulting from unauthorized or
                          fraudulent telephone transactions on your account. If Vanguard fails to
                          follow reasonable security procedures, it may be liable for any losses

                       INVESTMENT OBJECTIVES AND POLICIES
 
     The following policies supplement the Fund's investment objectives and
policies set forth in the Prospectus.
 
     FOREIGN INVESTMENTS  As indicated in the Prospectus, each Portfolio may
include foreign securities to the extent noted in the Portfolio's description.
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 Portfolio may temporarily hold uninvested
reserves in bank deposits in foreign currencies, the Portfolio will be affected
favorably or unfavorably by changes in currency rates and in exchange control
regulations, and may incur costs in connection with conversions between various
currencies. The investment policies of each Portfolio permit it to enter into
forward foreign currency exchange contracts in order to hedge the Portfolio's
holdings and commitments against changes in the level of future currency rates.
Such contracts involve an obligation to purchase or sell a specific currency at
a future date at a price set at the time of the contract.
 
     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 each Portfolio will endeavor to achieve most favorable execution
costs in its portfolio transactions in foreign securities, fixed commissions on
many foreign stock exchanges are generally higher than negotiated commissions on
U.S. exchanges. In addition, it is expected that the expenses for custodial
 
                                        1
<PAGE>   66
 
arrangements of the Portfolio's foreign securities will be somewhat greater than
the expenses for the custodian arrangements for handling U.S. securities of
equal value.
 
     Certain foreign governments levy withholding taxes against dividend and
interest income. Although in some countries a portion of these taxes is
recoverable, the non-recovered portion of foreign withholding taxes will reduce
the income the Portfolio receives from its foreign investments. However, these
foreign withholding taxes are not expected to have a significant impact on the
Portfolios, since each Portfolio's investment objective is to seek long-term
capital appreciation and any income should be considered incidental.
 
     PORTFOLIO TURNOVER  While the rate of Portfolio turnover is not a limiting
factor when management deems changes appropriate, it is anticipated that each
Portfolio's annual portfolio turnover rate will not normally exceed 100%. One
way a portfolio turnover rate of 100% can occur is if all of the Portfolio's
securities, exclusive of U.S. Government securities and other securities whose
maturities at the time of acquisition are one year or less, are replaced in the
period of one year. Turnover rates may vary greatly from year to year as well as
within a particular year and may also be affected by cash requirements for
redemptions of each Portfolio's shares and by requirements which enable the Fund
to receive certain favorable tax treatments. The portfolio turnover rates will,
of course, depend in large part on the level of purchases and redemptions of
shares of each Portfolio. Higher portfolio turnover can result in corresponding
increases in brokerage costs to the Portfolios of the Fund and their
shareholders.
 
                              INVESTMENT POLICIES
 
     FUTURES CONTRACTS  The Fund may enter into futures contracts, options, and
options on futures contracts for several reasons: to maintain cash reserves
while remaining fully invested, to facilitate trading, to reduce transaction
costs, or to seek higher investment returns when a futures contract is priced
more attractively than the underlying equity security or index. Futures
contracts provide for the future sale by one party and purchase by another party
of a specified amount of a specific security at a specified future time and at a
specified price. Futures contracts which are standardized as to maturity date
and underlying financial instrument are traded on national futures exchanges.
Futures exchanges and trading are regulated under the Commodity Exchange Act by
the Commodity Futures Trading Commission ("CFTC"), a U.S. Government Agency.
 
     Although futures contracts by their terms call for actual delivery or
acceptance of the underlying securities, in most cases the contracts are closed
out before the settlement date without the making or taking of delivery. Closing
out an open futures position is done by taking an opposite position ("buying" a
contract which has previously been "sold," or "selling" a contract previously
purchased) in an identical contract to terminate the position. Brokerage
commissions are incurred when a futures contract is bought or sold.
 
     Futures traders are required to make a good faith margin deposit in cash or
government securities with a broker or custodian to initiate and maintain open
positions in futures contracts. The Fund's margin deposits will be placed in a
segregated account maintained by the Fund's custodian bank. 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 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, payment of
additional "variation" margin will be required. Conversely, change in the
contract value may reduce the required margin, resulting in a repayment of
excess margin to the contract holder. Variation margin payments are made to and
from the futures broker for as long as the contract remains open. The Fund
expects to earn interest income on its margin deposits.
 
     Traders in futures contracts may be broadly classified as either "hedgers"
or "speculators." Hedgers use the futures markets primarily to offset
unfavorable changes in the value of securities otherwise held for
 
                                        2
<PAGE>   67
 
investment purposes or expected to be acquired by them. Speculators are less
inclined to own the securities underlying the futures contracts which they
trade, and use futures contracts with the expectation of realizing profits from
fluctuations in the prices of underlying securities.
 
     Regulations of the CFTC applicable to the Fund require that all of its
futures transactions constitute bonafide hedging transactions. The Fund will
only sell futures contracts to protect securities it owns against price declines
or purchase contracts to protect against an increase in the price of securities
it intends to purchase. As evidence of this hedging interest, the Fund expects
that approximately 75% of its futures contract purchases will be "completed,"
that is, equivalent amounts of related securities will have been purchased or
are being purchased by the Fund upon sale of open futures contracts.
 
     Although techniques other than the sale and purchase of futures contracts
could be used to control the Fund's exposure to market fluctuations, the use of
futures contracts may be a more effective means of hedging this exposure. While
the Fund will incur commission expenses in both opening and closing out futures
positions, these costs are lower than transaction costs incurred in the purchase
and sale of the underlying securities.
 
     RESTRICTIONS ON THE USE OF FUTURES CONTRACTS  The Fund will not enter into
futures contract transactions to the extent that, immediately thereafter, the
sum of its initial margin deposits on open contracts exceeds 5% of the market
value of the Fund's total assets. In addition, the Fund will not enter into
futures contracts to the extent that its outstanding obligations to purchase
securities under these contracts would exceed 20% of the Fund's total assets.
 
     RISK FACTORS IN FUTURES TRANSACTIONS  Positions in futures contracts may be
closed out only on an Exchange which provides a secondary market for such
futures. However, there can be no assurance that a liquid secondary market will
exist for any particular futures contract at any specific time. Thus, it may not
be possible to close a futures position. In the event of adverse price
movements, the Fund would continue to be required to make daily cash payments to
maintain its required margin. In such situations, if the Fund has insufficient
cash, it may have to sell portfolio securities to meet daily margin requirements
at a time when it may be disadvantageous to do so. In addition, the Fund may be
required to make delivery of the instruments underlying futures contracts it
holds. The inability to close options and futures positions also could have an
adverse impact on the ability to effectively hedge.
 
     The Fund will minimize the risk that it will be unable to close out a
futures contract by only entering into futures which are traded on national
futures exchanges and for which there appears to be a liquid secondary market.
 
     The risk of loss in trading futures contracts in some strategies can be
substantial, due both to the low margin deposits required, and the extremely
high degree of leverage involved in futures pricing. As a result, a relatively
small price movement in a futures contract may result in immediate and
substantial loss (as well as gain) to the investor. For example, if at the time
of purchase, 10% of the value of the futures contract is deposited as margin, a
subsequent 10% decrease in the value of the futures contract would result in a
total loss of the margin deposit, before any deduction for the transaction
costs, if the account were then closed out. A 15% decrease would result in a
loss equal to 150% of the original margin deposit if the contract were closed
out. Thus, a purchase or sale of a futures contract may result in losses in
excess of the amount invested in the contract. However, because the futures
strategies of the Fund are engaged in only for hedging purposes, the Adviser
does not believe that the Fund is subject to the risks of loss frequently
associated with futures transactions. The Fund would presumably have sustained
comparable losses if, instead of the futures contract, it had invested in the
underlying financial instrument and sold it after the decline.
 
     Utilization of futures transactions by the Fund does involve the risk of
imperfect or no correlation where the securities underlying futures contracts
have different maturities than the portfolio securities being hedged. It is also
possible that the Fund could both lose money on futures 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 the Fund has an open position in a futures contract or related
 
                                        3
<PAGE>   68
 
option. Additionally, investments in futures contracts and options involve the
risk that the investment advisers will incorrectly predict stock market and
interest rate trends.
 
     Most futures exchanges limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price at the end of a trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price beyond that limit. The daily limit governs only
price movement during a particular trading day and therefore does not limit
potential losses, because the limit may prevent the liquidation of unfavorable
positions. Futures contract prices have occasionally moved to the daily limit
for several consecutive trading days with little or no trading, thereby
preventing prompt liquidation of future positions and subjecting some futures
traders to substantial losses.
 
     FEDERAL TAX TREATMENT OF FUTURES CONTRACTS  Except for transactions the
Fund has identified as hedging transactions, the Fund is required for Federal
income tax purposes to recognize as income for each taxable year its net
unrealized gains and losses on certain futures contracts as of the end of the
year as well as those actually realized during the year. In most cases, any gain
or loss recognized with respect to a futures contract is considered to be 60%
long-term capital gain or loss and 40% short-term capital gain or loss, without
regard to the holding period of the contract. Furthermore, sales of futures
contracts which are intended to hedge against a change in the value of
securities held by the Fund may affect the holding period of such securities
and, consequently, the nature of the gain or loss on such securities upon
disposition.
 
     In order for the Fund to continue to qualify for Federal income tax
treatment as a regulated investment company, at least 90% of its gross income
for a taxable year must be derived from qualifying income; i.e., dividends,
interest, income derived from loans of securities, gains from the sale of
securities or foreign currencies or other income derived with respect to the
Fund's business of investing in securities. In addition, gains realized on the
sale or other disposition of securities held for less than three months must be
limited to less than 30% of the Fund's annual gross income. It is anticipated
that any net gain realized from the closing out of futures contracts will be
considered gain from the sale of securities and therefore be qualifying income
for purposes of the 90% requirement. In order to avoid realizing excessive gains
on securities held less than three months, the Fund may be required to defer the
closing out of futures contracts beyond the time when it would otherwise be
advantageous to do so. It is anticipated that unrealized gains on futures
contracts, which have been open for less than three months as of the end of the
Fund's fiscal year and which are recognized for tax purposes, will not be
considered gains on sales of securities held less than three months for the
purpose of the 30% test.
 
     The Fund will distribute to shareholders annually any net capital gains
which have been recognized for Federal income tax purposes (including unrealized
gains at the end of the Fund's fiscal year) on futures transactions. Such
distributions will be combined with distributions of capital gains realized on
the Fund's other investments and shareholders will be advised on the nature of
the transactions.
 
     REPURCHASE AGREEMENTS  Each Portfolio may invest in repurchase agreements
with commercial banks, brokers or dealers either for defensive purposes due to
market conditions or to generate income from its excess cash balances. A
repurchase agreement is an agreement under which the Fund acquires a money
market instrument (generally a security issued by the U.S Government or an
agency thereof, a banker's acceptance or a certificate of deposit) from a
commercial bank, broker or dealer, subject to resale to the seller at an agreed
upon price and date (normally, the next business day). A repurchase agreement
may be considered a loan collateralized by securities. The resale price reflects
an agreed upon interest rate effective for the period the instrument is held by
the Portfolio and is unrelated to the interest rate on the underlying
instrument. In these transactions, the securities acquired by the Portfolio
(including accrued interest earned thereon) must have a total value in excess of
the value of the repurchase agreement and are held by the Fund's Custodian Bank
until repurchased. In addition, the Fund's Board of Directors will monitor the
Fund's repurchase agreement transactions generally and will establish guidelines
and standards for review by the investment adviser of the creditworthiness of
any bank, broker or dealer party to a repurchase agreement with any Portfolio of
the Fund. No more than an aggregate of 10% of a Portfolio's assets, at the time
of investment, will be invested in
 
                                        4
<PAGE>   69
 
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.
 
     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
Portfolio 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 the Portfolio not within the
control of the Portfolio and therefore the realization by the Portfolio on such
collateral may be automatically stayed. Finally, it is possible that the
Portfolio may not be able to substantiate its interest in the underlying
security and may be deemed an unsecured creditor of the other party to the
agreement. While the Fund's management acknowledges these risks, it is expected
that they can be controlled through careful monitoring procedures.
 
     LENDING OF SECURITIES  Each Portfolio may lend its securities on a
short-term basis (less than nine months) 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 securities, the Portfolio will be
attempting to increase its net investment income through the receipt of interest
on the loan. Any gain or loss in the market price of the securities loaned that
might occur during the term of the loan would be for the account of the
Portfolio. Each Portfolio may lend its 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 require that (a) the borrower pledge and maintain
with the Fund collateral consisting of cash, an irrevocable letter of credit or
securities issued or guaranteed by the United States Government having a value
at all times not less than 100% of the value of the securities loaned, (b) the
borrower add to such collateral whenever the price of the securities loaned
rises (i.e., the borrower "marks to the market" on a daily basis), (c) the loan
be made subject to termination by the Portfolio at any time and (d) the
Portfolio receives 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. A Portfolio will not lend its portfolio securities, if as a
result, the aggregate value of such loans exceeds 33 1/3% of the value of the
Portfolio's total assets. 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 credit-worthiness of
the broker, dealer or institution, will be considered in making decisions with
respect to the lending of securities, subject to review by the Fund's Board of
Directors.
 
     At the present time, the Staff of the Commission does not object if an
investment company pays reasonable negotiated fees in connection with loaned
securities, so long as such fees are set forth in a written contract and
approved by the investment company's Directors (Trustees). In addition, voting
rights may pass with the loaned securities, but if a material event will occur
affecting an investment on loan, the loan must be called and the securities
voted.
 
                             INVESTMENT LIMITATIONS
 
     The following policies supplement the Fund's investment limitations set
forth in the Prospectus. It is a fundamental policy of each Portfolio not to
engage in any of the following activities or business practices. These
restrictions may not be changed with respect to a particular Portfolio without
the approval of a majority of the outstanding shares (as defined in the
Investment Company Act of 1940) of that Portfolio. A Portfolio may not:
 
      1) Issue senior securities;
 
      2) Borrow money, except from banks (or through reverse repurchase
         agreements), for temporary or emergency (not leveraging) purposes,
         including the meeting of redemption requests which might
 
                                        5
<PAGE>   70
 
         otherwise require the untimely disposition of securities, in an amount
         not in excess of 15% of the value of the net assets of the Portfolio
         (including the amount borrowed and the value of any outstanding reverse
         repurchase agreements) at the time the borrowing is made. Whenever
         borrowings exceed 5% of the value of the net assets of the Portfolio,
         the Portfolio will not make any additional investments;
 
      3) With respect to 75% of the value of its total assets, purchase the
         securities of any issuer (except obligations of the United States
         government and its instrumentalities) if as a result the Portfolio
         would hold more than 10% of the outstanding voting securities of the
         issuer, or more than 5% of the value of the Portfolio's total assets
         would be invested in the securities of such issuer;
 
      4) Engage in the business of underwriting securities issued by others,
         except to the extent that the Portfolio may technically be deemed to be
         an underwriter under the Securities Act of 1933, as amended, in
         disposing of portfolio securities;
 
      5) Purchase or otherwise acquire any security if, as a result, more than
         15% of its net assets would be invested in securities that are illiquid
         (including the Fund's investment in The Vanguard Group, Inc., as
         described on page 6);
 
      6) Make loans except (i) by purchasing bonds, debentures or similar
         obligations (including repurchase agreements, subject to the limitation
         described in (5) above) which are either publicly distributed or
         customarily purchased by institutional investors, and (ii) by lending
         its securities to banks, brokers, 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 Commission thereunder and the aggregate value of all securities
         loaned does not exceed 33 1/3% of the market value of the Portfolio's
         total assets;
 
      7) Pledge, mortgage, or hypothecate its assets, except to secure
         borrowings permitted by limitation (2) above;
 
      8) Buy any securities or other property on margin (except for such
         short-term credits as are necessary for the clearance of transactions),
         or engage in short sales (unless by virtue of its ownership of other
         securities it has a right to obtain at no added cost securities
         equivalent in kind and amount to the securities sold) except as set
         forth below in (12);
 
      9) Purchase or sell puts or calls, or combinations thereof; provided
         however, that a Portfolio may enter into forward foreign currency
         exchange transactions except as set forth below in (12);
 
     10) Purchase or sell real estate or real estate limited partnerships
         (although it may purchase securities secured by real estate interests
         or interests therein, or issued by companies or investment trusts which
         invest in real estate or interests therein);
 
     11) The Fund will not 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 Fund will invest only in investment companies which have
         investment objectives and investment policies consistent with those of
         the Fund;
 
     12) Purchase or sell commodities or commodity contracts; provided, however,
         that a Portfolio may enter into forward foreign currency exchange
         transactions and that each Portfolio may invest in futures contracts
         and options to the extent that not more than 5% of the portfolios
         assets are required as deposit to secure obligations under futures
         contracts and not more than 20% of a portfolio's assets are invested in
         futures contracts and options at any time;
 
     13) Invest in companies for the purpose of exercising control of
         management.
 
     Notwithstanding these limitations, the Fund may own all or any portion of
the securities of, 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
 
                                        6
<PAGE>   71
 
   
at cost services, such as management, administrative, distribution or other
related services to the Fund and other investment companies. (See "Management of
the Fund").
    
 
     In addition, no Portfolio may engage in any of the following activities;
however, these restrictions may be changed by the Directors without shareholder
approval or prior notification:
 
      1) Invest directly in oil, gas, or other mineral exploration or
         development programs, including oil & gas or other mineral leases;
         provided, however, that if consistent with the designated business
         activities of a particular Portfolio, a Portfolio may purchase
         securities of issuers whose principal business activities fall within
         such areas;
 
      2) Purchase warrants, valued at the lower of cost or market, in excess of
         5% of the value of the Fund's net assets. Including within that amount,
         but not to exceed 2% of the value of the Fund's net assets, may be
         warrants which are not listed on the New York or American Stock
         Exchange. Warrants acquired by a Portfolio at any time in units or
         attached to securities are not subject to this restriction.
 
     In order to permit the sale of shares of the Fund in certain states, the
Fund may make commitments more restrictive than the fundamental or
non-fundamental operating restrictions described above. Should the Fund
determine that any such commitment is no longer in the best interests of the
Fund and its shareholders it will revoke the commitment by terminating sales of
its shares in the state(s) involved.
 
     The above-mentioned investment limitations are considered at the time
investment securities are purchased.
 
                             MANAGEMENT OF THE FUND
 
   
     THE VANGUARD GROUP  The Fund is a member of The Vanguard Group of
Investment Companies which consists of the 32 investment companies. Through
their jointly-owned subsidiary, The Vanguard Group, Inc. ("Vanguard"), the
Vanguard Funds 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 Vanguard Money Market Reserves,
Vanguard Index Trust, Vanguard Admiral Funds, Vanguard International Equity
Index Fund, Vanguard Balanced Index Fund, Vanguard Institutional Index Fund,
Vanguard Bond Index Fund, Vanguard Institutional Money Market Portfolio,
Vanguard Municipal Bond Fund, several Portfolios of Vanguard Fixed Income
Securities Fund, several Portfolios of Vanguard Variable Insurance Fund and
Vanguard's State Tax-Free Funds (California, Florida, New York, New Jersey, Ohio
and Pennsylvania).
    
 
     Vanguard employs a supporting staff of management 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 procedures
approved by the Directors (Trustees) of each Fund. In addition, each Fund bears
its own direct expenses such as legal, auditing and custodian fees.
 
     The Officers of the Fund and the Vanguard Funds are also Officers and
employees of Vanguard. No Officer or employee is permitted to own any securities
of any external adviser for the Vanguard Funds.
 
   
     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. At the year ended January
31, 1994 the Fund had contributed capital of $382,000 to Vanguard representing
1.9% of its capitalization. The Fund's Service Agreement provides as follows:
(a) each Vanguard Fund may invest up to .40% of its current assets in Vanguard,
and (b) there is no other limitation on the amount that each Vanguard Fund may
contribute to Vanguard's capitalization. The amount contributed to Vanguard by
the Fund's Portfolios included the Service Economy and Technology Portfolios
which are no longer in existence.
    
 
     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 each Fund and choose its Officers. The following is a list of the Directors
and Officers of the Funds and a statement of their present positions and
principal occupations during the past five years. The mailing address of the
Directors and Officers of the Fund is Post Office Box 876, Valley Forge, PA
19482.

     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 Vanguard Funds by third parties. The
fees charged to shareholders in the redemption of capital shares of the Fund are
credited by Vanguard to the respective Portfolio (except for the Utilities
Income Portfolio) and are utilized to reduce the cost of such services. The
Utilities Income Portfolio does not assess a redemption fee; its costs for
corporate, management and administrative services during the period ended
January 31, 1994 were $1,707,000. During the year ended January 31, 1994 the
Fund's share of these costs for the other Portfolios was completely offset by
the 1% fee charged on redemptions from the Fund for all Portfolios (except for
the Utilities Portfolio) of the Fund.
    
 
     DISTRIBUTION  Vanguard also provides all distribution and marketing
services for the Vanguard Funds. 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 Vanguard Funds based upon their relative net assets. The
remaining one half of these expenses is allocated among the Vanguard Funds based
upon each Fund's sales for the preceding 24 months relative to the total sales
of the Funds as a Group. Provided, however, that no Fund's aggregate quarterly
rate of contribution for distribution expenses of a marketing and promotional
nature shall exceed 125% of the average distribution
 
                                        8
<PAGE>   73
 
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.
 
     INVESTMENT ADVISORY SERVICES  An experienced investment management staff
employed directly by Vanguard provides investment advisory services to Vanguard
Money Market Reserves, Vanguard Institutional Money Market Portfolio, Vanguard
Municipal Bond Fund, several Portfolios of Vanguard Fixed Income Securities Fund
and Vanguard's State Tax-Free Funds (California, New York, New Jersey, Ohio and
Pennsylvania). The compensation and other expenses of this staff are paid by the
Portfolios and Funds utilizing these services.
 
   
     REMUNERATION OF DIRECTORS AND OFFICERS  The Fund will pay each Director who
is not also an Officer, an annual fee plus travel and other expenses incurred in
attending Board meetings. During the year ended January 31, 1994 the Fund paid
approximately $9,000 in Director's fees. Directors who are also Officers receive
no remuneration for their services as Directors. 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 by Vanguard (and reimbursed by the Fund) during the fiscal
year to all Officers of the Fund, as a group, was approximately $84,941.
    
 
   
     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 an eligible
Officer's compensation during the year, if any, that exceeds the Social Security
Taxable Wage Base then in effect. Under its Thrift Plan, all employees of
Vanguard are permitted to make pre-tax basic contributions in a maximum amount
equal to 4% of total compensation. Vanguard matches the basic contributions on a
100% basis. The Fund's proportionate share of benefits paid by Vanguard under
its retirement and thrift plans to all Officers of the Fund, as a group, during
the fiscal year ended January 31, 1994 was approximately $11,663.
    
 
     DIRECTORS' RETIREMENT FEES  A Retirement Plan for Directors has been
implemented to provide a fee to retired Directors equal to $1,000 per year of
service on the Board, up to 15 years of service. This fee will remain in place
subsequent to the Director's retirement for a period of 10 years or until a
retired Director's death.
 
                          INVESTMENT ADVISORY SERVICES
 
   
     INVESTMENT ADVISORY AGREEMENT WITH WELLINGTON MANAGEMENT COMPANY  The Fund
employs Wellington Management Company ("WMC") under an investment advisory
agreement dated as of May 1, 1984 to manage the investment and reinvestment of
the assets of the Fund's Energy, Health Care, and Utilities Income Portfolios
and to continuously review, supervise and administer each Portfolio's investment
program. WMC discharges its responsibilities subject to the control of the
officers and Directors of the Fund.
    
 
   
     Under the investment advisory agreement, the three Portfolios are required
to pay the Adviser an aggregate fee at the end of each fiscal quarter,
calculated by applying a quarterly rate, based on the following annual
percentage rates, to the aggregate average month-end net assets of the
Portfolios for the quarter:
    
 
<TABLE>
<CAPTION>
                                       NET ASSETS                                      RATE

    Next $500 million...............................................................  0.125%
    Over $1 billion.................................................................  0.100%
</TABLE>
 
   
     The advisory fee is based on the total assets of the Portfolios and is
allocated to each Portfolio based on the relative net assets of each. In
addition, once the advisory fee to WMC is calculated for the five Portfolios
under this schedule, the total fee will be reduced in order that the advisory
fee paid by the Utilities Income Portfolio does not exceed 0.125%. During the
years ended January 31, 1992, 1993 and 1994 the Fund paid to WMC advisory fees
totaling $1,409,000, $1,481,000 and $2,079,000 respectively, which represented
an effective annual rate of .25 of 1%, .16 of 1%, .14 of 1% respectively, of
average net assets of the Energy, Health Care, and Utilities Income Portfolios.
    
 
                                        9
<PAGE>   74
 
   
     WMC's fees during the fiscal years ended January 31, 1992, 1993 and 1994
were payable under a prior investment advisory agreement. The assets on which
advisory fees for the 1994 fiscal year were based included the Service Economy
and Technology Portfolios, which are no longer in existence.
    
 
   
     The current agreement will continue until May 30, 1995 and will be
renewable thereafter, for successive one year periods, only if each renewal is
specifically approved by a vote of the Fund's Board of Directors, including the
affirmative votes of a majority of the Directors who are not parties to the
agreement or "interested persons" (as defined in the Investment Company Act of
1940) of any such party cast in person at a meeting called for the purpose of
considering such approval. In addition, the question of continuance of the
agreement may be presented to the shareholders of the Fund; in such event
continuance shall be effected only if approved by the affirmative vote of a
majority of the outstanding voting securities of the Fund. If the holders of any
Portfolio fail to approve the agreement, WMC may continue to serve as investment
adviser to each Portfolio which approved the agreement, and to any Portfolio
which did not approve the agreement until new arrangements have been made. The
agreement is automatically terminated if assigned, and may be terminated by any
Portfolio without penalty, at any time, (1) either by vote of the Board of
Directors or by vote of the outstanding voting securities of the Portfolio on
sixty (60) days' written notice to WMC, or (2) by WMC upon ninety (90) days'
written notice to the Fund.
    
 
     DESCRIPTION OF WMC  WMC is a Massachusetts general partnership, of which
the following persons are managing partners: Robert W. Doran, Duncan M.
McFarland, and John B. Neff.
 
     INVESTMENT ADVISORY AGREEMENT WITH M & G GROUP P.L.C.  The Fund has also
entered into an investment advisory agreement with M & G Investment Management
Limited ("M & G"), effective February 1, 1987 to manage the assets of the Gold &
Precious Metals Portfolio. Under this agreement M & G manages the investment and
reinvestment of the assets of the Gold & Precious Metals Portfolio and
continuously renews, supervises and administers the Portfolio's investment
program. M & G will discharge its responsibilities subject to the control of the
officers and Directors of the Fund.
 
   
     DESCRIPTION OF M & G  M & G is a wholly-owned subsidiary of the M & G Group
P.L.C. M & G Group P.L.C. is a public company whose shares are quoted on the
London Stock Exchange. Kleinwort, Benson Limited, a merchant bank, and the Esmee
Fairbairn Charitable Trust own respectively 42% and 32% of
total shares outstanding. The remaining 26% of shares are held by individuals,
nominees, pension plans and
M & G employees.
    
 
   
     The Gold & Precious Metals Portfolio will pay M & G a fee at the end of
each fiscal quarter, calculated by applying a quarterly rate, based on the
following annual percentage rates, to the aggregate average month-end net assets
of the Portfolio for the quarter:

</TABLE>
 
   
     During the years ended January 31, 1992, 1993 and 1994, the Gold & Precious
Metals Portfolio paid an advisory fees of $477,000, $506,000, and $924,000
respectively, to M & G which represented an effective annual rate of .28 of 1%,
.28 of 1%, and .22 of 1% respectively, of average net assets.
    
 
   
                            SECURITIES TRANSACTIONS
    
 
     The investment advisory agreements with WMC and M & G authorize the
investment adviser (with the approval of the Fund's Board of Directors) to
select the brokers or dealers that will execute the purchases and sales of
securities for the Fund's Portfolio(s) and directs the investment adviser to use
its best efforts to obtain the best available price and most favorable execution
with respect to all transactions for the Portfolio(s). Each investment adviser
has undertaken to execute each investment transaction at a price and commission
which provides the most favorable total cost or proceeds reasonably obtainable
under the circumstances.
 
                                       10
<PAGE>   75
 
     In placing portfolio transactions, each investment adviser will use its
best judgment to choose the broker most capable of providing the brokerage
services necessary to obtain best available price and most favorable execution.
The full range and quality of brokerage services available will be considered in
making these determinations. In those instances where it is reasonably
determined that more than one broker can offer the brokerage services needed to
obtain the best available price and most favorable execution, consideration may
be given to those brokers which supply investment research and statistical
information, and provide other services in addition to execution services to the
Fund and/or the investment adviser. Each investment adviser considers the
investment services it receives useful in the performance of its obligations
under the agreement but is unable to determine the amount by which such services
may reduce its expenses.
 
     The investment advisory agreements also incorporate the concepts of Section
28(e) of the Securities Exchange Act of 1934 by providing that, subject to the
approval of the Fund's Board of Directors, each investment adviser may cause the
Fund to pay a broker-dealer which furnishes brokerage and research services a
higher commission than that which might be charged by another broker-dealer for
effecting the same transaction; provided that such commission is deemed
reasonable in terms of either that particular transaction or the overall
responsibilities of the investment adviser to the Fund and the other Funds in
the Group.
 
     Currently, it is the Fund's policy that each investment adviser may at
times pay higher commissions in recognition of brokerage services felt necessary
for the achievement of better execution of certain securities transactions that
otherwise might not be available. An investment adviser will only pay such
higher commissions if it believes this to be in the best interest of the Fund.
Some brokers or dealers who may receive such higher commissions in recognition
of brokerage services related to execution of securities transactions are also
providers of research information to the investment adviser and/or the Fund.
However, the investment adviser has informed the Fund that it will not pay
higher commission rates specifically for the purpose of obtaining research
services.
 
     Since the Fund does not market its shares through intermediary brokers or
dealers, it is not the Fund's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be made through such
firms. However, the Fund may place portfolio orders with qualified
broker-dealers who recommend the sale of shares of the Fund and may, when a
number of brokers and dealers can provide comparable best price and execution on
a particular transaction, consider the sale of Fund shares by a broker or dealer
in selecting among qualified broker-dealers.
 
   
     The total brokerage commissions paid by each of the Fund's Portfolios
during the fiscal years ended January 31, 1992, 1993 and 1994 totaled $700,790,
$1,346,501, and $3,334,211, respectively.
    
 
     Some securities considered for investment by one Portfolio may also be
appropriate for the other Portfolios and the other Funds and/or clients served
by the investment advisers. If purchase or sale of securities consistent with
the investment policies of a Portfolio, the other Portfolios and/or one or more
of these other Funds or clients are considered at or about the same time,
transactions in such securities will be allocated among the Portfolios and the
several Funds and clients in a manner deemed equitable by the respective
investment adviser. Although there will be no specified formula for allocating
such transactions, the allocation methods used, and the results of such
allocations, will be subject to periodic review by the Fund's Board of
Directors.
 
                               PURCHASE OF SHARES
 
     The Fund reserves the right in its sole discretion (i) to suspend the
offering of its shares, (ii) to reject purchase orders when in the judgment of
management such rejection is in the best interest of the Fund or any Portfolio,
and (iii) to reduce or waive the minimum for initial and subsequent investments
for certain fiduciary accounts such as employee benefit plans or under
circumstances where certain economies can be achieved in sales of the Fund's
shares.
 
     STOCK CERTIFICATES  Your purchase will be made in full and fractional
shares of a Portfolio calculated to three decimal places. Shares are normally
held on deposit for shareholders by the Fund, which will send to shareholders a
statement of shares owned at the time of each transaction. This saves the
shareholders the
 
                                       11
<PAGE>   76
 
trouble of safe-keeping the certificates, and saves the Fund the cost of issuing
certificates. Except in the case of the Utilities Income Portfolio, share
certificates are available at any time upon written request at no additional
cost to shareholders. No certificates will be issued for the Utilities Income
Portfolio or for any fractional shares of the Fund's other Portfolios.
 
                              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% or 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 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.

and/or the average expense ratio of the small company growth funds. (This fund
category was first established in 1982. For years prior to 1982, the results of
the Lipper Small Company Growth category were estimated using the returns of the
Funds that constituted the Group at its inception.)

     In assessing such comparisons of yields, an investor should keep in mind
that the composition of the investments in the reported averages is not
identical to the Fund's Portfolio and that the items included in the
calculations of such averages may not be identical to the formula used by the
Fund to calculate its yield. In addition there can be no assurance that the 
Fund will continue its performance as compared to such other averages.

Insofar as indemnification for liability arising under the Securities Act of

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 trustee, 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
<PAGE>   80
 
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.
