</TABLE>
YIELD AND TOTAL RETURN
          From time to time the Fund advertises its yield and total return.
          Both yield and total return figures are based on historical
          earnings and are not intended to indicate future performance. The
          "total return" of the Fund refers to the average annual compounded
          rates of return over one-, five- and ten-year periods or over the
          life of the Fund (as stated in the advertisement) that would
          equate an initial amount invested at the beginning of a stated
          period to the ending redeemable value of the investment, assuming
          the reinvestment of all dividend and distributions.

          In accordance with industry guidelines set forth by the U.S.
          Securities and Exchange Commission, the "30-day yield" of the Fund
          is calculated by dividing the net investment income per share
          earned during a 30-day period by the net asset value per share on
          the last day of the period. Net investment income includes
          interest and dividend income earned on the Fund's securities; it
          is net of all expenses and all recurring and nonrecurring charges
          that have been applied to all shareholder accounts. The yield
          calculation assumes that the net investment income earned over 30
          days is compounded monthly for six months and then annualized.
          Methods used to calculate advertised yields are standardized for
          all stock and bond mutual funds. However, these methods differ
          from the accounting methods used by the Fund to maintain its books
          and records, and so the advertised 30-day yield may not fully
          reflect the income paid to an investor's account or the yield
          reported in the Fund's reports to shareholders. Additionally the
          Fund may compare its performance to that of the Merrill Lynch
          Perpetual Preferred Index.

INVESTMENT OBJECTIVE
The Fund seeks to provide qualified dividend income
          The Fund is an open-end diversified investment company. The
          objective of the Fund is to provide the maximum dividend income
          which qualifies for the corporate dividends received
          deduction (currently 70%) under federal tax law by
          investing primarily in the preferred stocks of domestic
          corporations. There is no assurance that the Fund will achieve its
          stated objective.

          The investment objective of the Fund is not fundamental and so may
          be changed by the Board of Trustees without shareholder approval.
- ----------------------------------------------------------------------------
INVESTMENT POLICIES
The Fund invests in preferred stocks
          Under normal circumstances, the Fund will invest more than 75% of
          its total assets in cumulative preferred stocks of domestic
          corporations which have been rated Baa or better by Moody's
          Investor Service, Inc. or BBB or better by Standard &
          Poor's Corporation. The remainder of the Fund's assets may be
          invested in (i) similarly rated fixed-income securities, including
          convertible preferred stocks and bonds, and money market
          instruments, and (ii) preferred stocks with lower ratings. The
          Fund will not sell any of the securities that it holds solely on
          account of such securities having been downgraded. Except for the
          qualified dividend income exclusion previously described, the Fund
          is managed without regard to tax ramifications.

          No investments will be made in common stocks. In the case of
          convertible securities, the conversion privilege may be exercised,
          but the common stocks received will be sold. The Fund will not
          ordinarily invest in non-cumulative or non-rated preferred stocks,
          but reserves the right to do so should market conditions dictate
          that it be in the best interests of the Fund and its shareholders.
          The Fund will not purchase warrants or rights directly and will
          not in any event hold rights or warrants to an extent greater than
          5% of its total assets. See "Implementation of Policies" for other
          investment practices of the Fund.

          The Fund is responsible for voting the shares of all securities it
          holds.

          These policies are not fundamental and so may be changed by the
          Board of Trustees without shareholder approval.
- ----------------------------------------------------------------------------
INVESTMENT RISKS
The Fund is subject to interest rate, credit and manager risks
          As a mutual fund investing primarily in perpetual preferred
          stocks, the Fund is subject to interest rate risk--i.e., the
          possibility that the market value of preferred stocks will vary
          inversely with interest rates. When interest rates rise, the value
          of preferred stocks will fall; when interest rates fall, the value
          of preferred stocks will rise.

          Perpetual preferred stocks are similar in many ways to corporate
          fixed-income securities; they provide investors with a fixed
          stream of income that is generated from corporate earnings.
          However, perpetual preferred stocks, unlike corporate bonds, do
          not have a stated maturity date. Because they lack a fixed
          maturity date, the prices of preferred stocks are extremely
          sensitive to changes in interest rates. Investors should
          anticipate that the fluctuations in market value of preferred
          stocks will generally exceed those of long-term government or
          corporate bonds (those with maturities of 15 to 30 years).

          As an illustration of interest rate risk, the table below depicts
          the effect of a one and two percentage point change in interest
          rates on long-term bonds:

                           -20.5%                        +28.6%

          This table is intended to provide you with guidelines for
          determining the degree of interest rate risk you may be willing to
          assume. The price changes shown should not be taken as
          representative of the Fund's current or future change in share
          price.

          In addition to interest rate risk, the Fund is also subject to a
          limited degree to credit risk--i.e., the likelihood that the
          issuing corporation will be unable to make the dividend payments
          due on its preferred stock. Credit risk in the Fund will be
          minimized by investing chiefly in investment grade preferred
          stocks, and by diversi- fying preferred stock investments among
          many companies and industries.

          The investment adviser manages the Fund according to the
          traditional methods of "active" investment management, which
          involve the buying and selling of securities based upon economic,
          financial and market analysis and investment judgment.
          Manager risk refers to the possibility that the Fund's investment
          adviser may fail to execute the Fund's investment strategy
          effectively. As a result, an investor in the Fund may lose money.
- ----------------------------------------------------------------------------
WHO SHOULD INVEST
Investors seeking income which qualifies for the dividends
received deduction
          The Fund is intended for investors who are seeking income from
          their investments and who can tolerate substantial price risks in
          pursuit of their income objectives. The Fund is suited to
          investors who are willing to hold their investments over a long
          time horizon in anticipation of the income that preferred stocks
          may provide. Because the Fund invests in preferred stocks,
          investors should be able to tolerate sharp, sometimes substantial
          fluctuations in the value of their investment due to changes in
          interest rates.

          By minimizing nonqualifying investment income (i.e., realized
          interest income and net realized short-term capital gains), the
          Fund is especially suitable for corporations seeking to benefit
          from the corporate dividends received deduction, which
          is currently 70%. Because of the tax considerations involved,
          the Fund may not be as suitable an investment for individuals,
          who, unlike corporations, are not permitted to exclude qualified
          dividends received from their taxable income.

          Because of the risks associated with stock investments,
          the Fund is intended to be a long-term investment vehicle
          and is not designed to provide investors with a

                                     5
<PAGE>
          means of speculating on short-term stock market movements.
          Investors who en-gage 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.

          Given its objectives and risks, the Fund is not intended as 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 POLICIES
The Fund may invest in short-term fixed income securities
          In addition to investing in preferred stocks, the Fund follows a
          number of additional investment policies.

          Although it normally seeks to remain substantially invested in
          preferred stocks, the Fund may invest temporarily in certain
          short-term fixed income securities. Such securities may be used to
          invest uncommitted cash balances or to maintain liquidity to meet
          shareholder redemptions. Under normal circumstances, the Fund
          will invest no more than 35% of its assets in short-term fixed
          income securities. However, the Fund reserves the right to invest
          100% of its assets in such securities for temporary defensive
          purposes. These short-term fixed income 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 Fund may lend its securities
          The Fund may lend its investment securities on a short-term or a
          long-term basis to qualified institutional investors for the
          purpose of realizing additional income. Loans of securities by the
          Fund will be collateralized by cash, letters of credit, or
          securities issued or guaranteed by the U.S. Government or its
          agencies. The collateral will equal at least 100% of the current
          market value of the loaned securities.

The Fund may borrow money
          The Fund may borrow money, subject to the limits set forth on page
          8, for temporary or emergency purposes, including the meeting of
          redemption requests which might otherwise require the untimely
          disposition of securities.

Portfolio turnover is not expected to exceed 100%
          Although it generally seeks to invest for the long term, the Fund
          retains the right to sell securities irrespective of how long they
          have been held. It is anticipated that the Fund's annual turnover
          rate will not exceed 100%. A turnover rate of 100% would occur,
          for example, if all of the securities of the Fund were replaced
          within one year.

Derivative Investing
          Derivatives are instruments whose values are linked to or derived
          from an underlying security or index. The most common and
          conventional types of derivative securities are futures and
          options.

                                     6
<PAGE>
The Fund may invest in derivative securities

          The Fund may invest in futures contracts and options, but only to
          a limited extent. Specifically, the Fund may enter into futures
          contracts provided that not more than 5% of its assets are
          required as a futures contract deposit; in addition, the Fund may
          enter into futures contracts and options transactions only to the
          extent that obligations under such contracts or transactions
          represent not more than 20% of the Fund's assets.

          Futures contracts and options may be used for several common fund
          management strategies: to maintain cash reserves while simulating
          full investment, to facilitate trading, to reduce transaction
          costs, or to seek higher investment returns when a specific
          futures contract is priced more attractively than other futures
          contracts or the underlying security or index.

          The Fund may use futures contracts for bona fide "hedging"
          purposes. In executing a hedge, a manager sells, for example,
          stock index futures to protect against a decline in the stock
          market. As such, if the market drops, the value of the futures
          position will rise, thereby offsetting the decline in value of the
          Fund's stock holdings.

The Fund may invest in CMOs
          The Fund may also invest modestly in a fairly conservative class
          of collateralized mortgage obligations (CMOs) which feature a high
          degree of cash flow predictability and moderate vulnerability to
          mortgage prepayment risk. To reduce credit risk, Vanguard
          purchases these less risky classes of collateralized mortgage
          obligations issued only by agencies of the U.S. Government or
          privately-issued collateralized mortgage obligations that carry
          high-quality investment-grade ratings.

Futures contracts and options pose certain risks
          The primary risks associated with the use of futures contracts and
          options are: (i) imperfect correlation between the change in
          market value of the stocks or bonds held by the Fund and the
          prices of futures contracts and options; and (ii) possible lack of
          a liquid secondary market for a futures contract and the resulting
          inability to close a futures position prior to its maturity date.
          The risk of imperfect correlation will be minimized by investing
          in those contracts whose price fluctuations are expected to
          resemble those of the Fund's underlying securities. The risk that
          the Fund will be unable to close out a futures position will be
          minimized by entering into such transactions on a national
          exchange with an active and liquid secondary market.
- ----------------------------------------------------------------------------
INVESTMENT LIMITATIONS
The Fund has adopted certain fundamental limitations
          The Fund has adopted certain limitations on its investment
          practices. Specifically, the Fund will not:

          (a) With respect to 75% of the value of its total assets, purchase
              the securities of any issuer (except obligations of the United
              States Government and its instrumentalities) if, as a result,
              the Fund would hold more than 10% of the outstanding voting
              securities of the issuer, or more than 5% of the value of the
              Fund's total assets would be invested in the securities of
              such issuer;
          (b) Invest more than 25% of its assets in any one industry, with
              the exception of the electric and/or gas industries; and

                                     7
<PAGE>
          (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 15% of the value
              of the Fund's net assets (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 Fund's net assets, the Fund will not make
              any additional investments.

          These investment limitations are considered at the time investment
          securities are purchased. The limitations described here and in
          the Statement of Additional Information may be changed only with
          the approval of a majority of the Fund's shareholders.
- ----------------------------------------------------------------------------
MANAGEMENT OF THE FUND
Vanguard administers and distributes the Fund
          The Fund is a member of The Vanguard Group of Investment
          Companies, a family of more than 30 investment companies with more
          than 90 distinct investment portfolios and total assets in excess
          of $240 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, shareholder accounting and
          distribution services. Vanguard also provides investment advisory
          services on an at-cost basis to certain Vanguard funds. As a
          result of Vanguard's unique corporate structure, the Vanguard
          funds have costs substantially lower than those of most competing
          mutual funds. In 1996, the average expense ratio (annual
          costs including advisory fees divided by total net assets) for the
          Vanguard funds amounted to approximately 0.29% compared to an
          average of 1.22% 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 Trustees. The Trustees set
          broad policies for the Fund and choose its Officers. A list of the
          Trustees and Officers of the Fund and a statement of their present
          positions and principal occupations during the past five years can
          be found in the Statement of Additional Information.

          Vanguard employs a supporting staff of management and
          administrative personnel needed to provide the requisite services
          to the funds and also furnishes the funds with necessary office
          space, furnishings and equipment. Each fund pays its share of
          Vanguard's total expenses, which are allocated among the funds
          under methods approved by the Board of Trustees (Directors) of
          each fund. In addition, each fund bears its own direct expenses,
          such as legal, auditing and custodian fees.

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

INVESTMENT ADVISER
Wellington Management Company, LLP manages the Fund's investments
          The Fund has entered into an investment advisory agreement with
          Wellington Management Company, LLP ("WMC"), 75 State
          Street, Boston, MA 02109, under which WMC manages the investment
          and reinvestment of the Fund's assets and continuously reviews,
          supervises and administers the Fund's investment program. WMC
          discharges its responsibilities subject to the control of the
          Fund's Officers and Trustees.

          WMC is a professional investment advisory firm which globally
          provides services to investment companies, other institutions and
          individuals. Among the clients of WMC are more than 10 investment
          companies of The Vanguard Group. As of October 31, 1996,
          WMC held investment management authority with respect to more than
          $130 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.

          Earl E. McEvoy, Senior Vice President of WMC, serves as portfolio
          manager of the Fund, a position he has held since October 1982.
          Mr. McEvoy also manages the Long-Term Corporate and High Yield
          Corporate Portfolios of Vanguard Fixed Income Securities Fund, as
          well as the High Yield Bond Portfolio of the Vanguard Variable
          Insurance Fund and the bond component of Vanguard/Wellesley Income
          Fund. Mr. McEvoy has been associated with Wellington Management
          Company for 19 years. Mr. McEvoy is supported by research
          and other investment services provided by the professional staff
          of WMC.

          The Fund pays WMC an advisory fee at the end of each fiscal
          quarter, calculated by applying a quarterly rate, based on the
          following annual percentage rates, to the Fund's average month-end
          net assets for the quarter:

                    Net Assets                                    Rate
                    ---------------------------------            -----
                    First $200 million                           .150%
                    Next $200 million                            .100%
                    Assets in excess of $400 million             .075%

          During the fiscal year which ended on October 31, 1996, the
          total advisory fees paid by the Fund to WMC represented an annual
          effective rate of .13 of 1% of the Fund's total average net
          assets. This fee was paid under a previous fee schedule that
          provided for a higher rate of fees.

          The investment advisory agreement with WMC authorizes the adviser
          to select brokers or dealers to execute purchases and sales of the
          Fund's portfolio securities, and directs the adviser to use its
          best efforts to obtain the best available price and most favorable
          execution with respect to all transactions. The full range and
          quality of brokerage services available are considered in making
          these determinations.

          The Fund has authorized WMC to pay higher commissions in recognition
          of brokerage services felt necessary for the achievement of better
          execution, provided the adviser believes this to be in the best
          interest of the Fund. Although the Fund does not market its shares
          through intermediary brokers or dealers, the Fund may


                                     9
<PAGE>
          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 Trustees may, without the approval of
          shareholders, provide for: (a) the employment of a new investment
          adviser pursuant to the terms of a new advisory agreement, either
          as a replacement for an existing adviser or as an additional
          adviser; (b) a change in the terms of an advisory agreement; and
          (c) the continued employment of an existing adviser on the same
          advisory contract terms where a contract has been assigned because
          of a change in control of the adviser. Any such change will only
          be made upon not less than 30 days' prior written notice to
          shareholders of the Fund which shall include substantially the
          information concerning the adviser that would have normally been
          included in a proxy statement.

PERFORMANCE RECORD
          The table below provides investment results for the Fund for
          several periods over the Fund's lifetime. The results represent
          the Fund's "total return" investment performance, which assumes
          the reinvestment of all capital gains and income dividends for the
          indicated periods. Also included is comparative information on the
          unmanaged Merrill Lynch Perpetual Preferred Index, a measure of
          the investment performance of preferred stocks. The table does not
          make any allowance for federal, state or local income taxes, which
          shareholders must pay on a current basis.

          The results shown should not be considered a representation of the
          total return from an investment made in the Fund today. This
          information is provided to help investors better understand the
          Fund and may not provide a basis for comparison with other
          investments or mutual funds which use a different method to
          calculate performance.

DIVIDENDS, CAPITAL GAINS AND TAXES
The Fund pays quarterly dividends
          The Fund expects to pay dividends quarterly from ordinary income.
          Net capital gains distributions, if any, will be made annually.

          In addition, in order to satisfy certain distribution
          requirements of the Tax Reform Act of 1986, the Fund
          may declare special year-end dividend and capital gains

                                     10
<PAGE>
          distributions during December. Such distributions, if received by
          shareholders by January 31, are deemed to have been paid by the
          Fund and received by shareholders on December 31 of the prior
          year.

          Dividend and capital gains distributions may be automatically
          reinvested or received in cash. See "Choosing a Distribution
          Option" for a description of these methods.

          The Fund intends to continue to qualify for taxation as a
          "regulated investment company" under the Internal Revenue Code so
          that it will not be subject to federal income tax to the extent
          its income is distributed to shareholders. Dividends paid by the
          Fund from net investment income, whether received in cash or
          reinvested in additional shares, will be taxable to shareholders
          as ordinary income.

Dividends will qualify for the dividends received deduction
          For corporate investors, if the Fund qualifies for taxation as a
          regulated investment company and satisfies certain requirements, a
          portion of the dividends paid by the Fund will be eligible,
          whether received in cash or reinvested in additional shares, for
          the corporate dividends received deduction, which is
          currently 70%. After such a deduction, the qualifying portion
          of the Fund's dividends would be subject to a maximum federal tax
          rate of 10.2%, in contrast to the current maximum federal
          corporate tax rate
          of 34%.

          In keeping with the policies and objectives of the Fund, the Fund
          will seek to maximize dividend income which qualifies for the
          corporate dividends received deduction. In fiscal year
          1996, all of the Fund's dividend distributions qualified
          for the dividends received deduction.

          In order to qualify for the corporate dividends received
          deduction, corporate shareholders must satisfy certain holding
          period requirements for the Fund's shares. Specifically, the
          deduction is only permitted when the Fund's shares have been held
          for more than 45 days. The holding period requirements apply to
          each block of Fund shares acquired, including each block of shares
          received in payment of the Fund's quarterly dividends. Corporate
          investors are advised to consult with their tax advisers on their
          eligibility for the dividends received deduction.

          Distributions paid by the Fund from long-term capital gains,
          whether received in cash or reinvested in additional shares, are
          taxable to shareholders, as long-term capital gains, regardless of
          the length of time the shareholder has owned the shares. Capital
          gains distributions result when the Fund realizes net capital
          gains on sales of portfolio securities. For the Fund, realized
          capital gains are not expected to be a significant or predictable
          part of investment return.

          Keep in mind that if you purchase shares shortly before the record
          date of a dividend or capital gains distribution, you will pay the
          full price for the shares and then receive some portion of the
          price back as a taxable dividend or capital gains distribution.

          The Fund notifies shareholders annually as to the tax status of
          distributions paid by the Fund. Except for qualification for the
          corporate dividends received deduction, the Fund is managed
          without regard to tax ramifications.

                                     11
<PAGE>
A capital gain or loss may be realized upon exchange or redemption
          A sale of shares of the Fund is a taxable event and may result in
          a capital gain or loss. A capital gain or loss may be realized
          from an ordinary redemption of shares or an exchange of shares
          between two mutual funds (or two portfolios of a mutual fund).
          Dividend distributions, capital gains distributions, and capital
          gains or losses from redemptions and exchanges may be subject to
          state and local taxes.

          The Fund is required to withhold 31% of taxable dividends, capital
          gains distributions, and redemptions paid to shareholders who have
          not complied with IRS taxpayer identification regulations. You may
          avoid this withholding requirement by certifying on your Account
          Registration Form your proper Social Security or Employer
          Identification number and by certifying that you are not subject
          to backup withholding.

          The Fund is organized as a Pennsylvania business trust and, in the
          opinion of counsel, is not liable for any income or franchise tax
          in the Commonwealth of Pennsylvania. The Fund will be subject to
          Pennsylvania county personal property tax in the county which is
          the site of its principal office. Shareholders who are residents
          of Pennsylvania will be exempt from county personal property
          taxes, except for shareholders who are residents of the City and
          School District of Pittsburgh.

          The tax discussion set forth above is included for general
          information only. Prospective investors should consult their own
          tax advisers concerning the tax consequences of an investment in
          the Fund.
- ----------------------------------------------------------------------------
THE SHARE PRICE OF THE FUND
          The Fund's share price or "net asset value" per share is
          determined by dividing the total assets of the Fund, less all
          liabilities, by the total number of shares outstanding. Net asset
          value is determined as of the regular close of the New York Stock
          Exchange (generally 4:00 p.m. Eastern time) on each day the
          exchange is open for trading. The Fund's net asset value includes
          interest on fixed-income securities which is accrued daily.

          Portfolio securities which are traded over-the-counter and
          on a stock exchange will be valued according to the broadest and
          most representative market, and it is expected that for bonds and
          other fixed-income securities (including preferred stocks) this
          market will ordinarily be the over-the-counter market. Valuation
          of such securities will be at the currently quoted bid price. When
          stock exchange valuations are used, the valuation will also be the
          latest quoted bid price on the day of valuation.

          Securities may be valued on the basis of prices provided by a
          pricing service when such prices are believed to better reflect
          the fair market value of such securities. The prices provided by a
          pricing service may be determined without regard to bid or last
          sale prices of each security but take into account institutional
          size trading in similar groups of securities and developments
          related to specific securities. Short-term instruments (those with
          remaining maturities of 60 days or less) may be valued

                                     12
<PAGE>
          at cost, plus or minus any amortized discount or premium, which
          approximates market. Other assets and securities for which market
          quotations are not readily available or which are restricted as to
          sale and other assets are valued by such methods as the Board of
          Trustees deems in good faith to reflect fair value.

          The Fund's share price can be found daily in the mutual fund
          listings of most major newspapers under the heading of Vanguard
          Group.

OPENING AN ACCOUNT AND PURCHASING SHARES
          You may open a regular (non-retirement) account, either by mail or
          wire. Simply complete and return an Account Registration Form and
          any required legal documentation, indicating the amount you wish
          to invest. Your purchase must be equal to or greater than the
          $3,000 minimum initial investment requirement ($1,000 for Uniform
          Gifts/Transfers to Minors Act accounts). You must open a new
          Individual Retirement Account by mail (IRAs may not be opened by
          wire) using a Vanguard IRA Adoption Agreement. Your purchase must
          be equal to or greater than the $1,000 minimum initial investment
          requirement, but no more than $2,000 if you are making a regular
          IRA contribution. Rollover contributions are generally limited to
          the amount withdrawn within the past 60 days from an IRA or other
          qualified Retirement Plan. If you need assistance with the forms
          or have any questions about this Fund, please call our Investor
          Information Department at 1-800-662-7447. Note: For other types of

          other organizations, trusts or powers of attorney), please call us
          to determine which additional forms you may need.

          The Fund's shares are purchased at the next-determined net asset
          value after your investment has been received. The Fund is offered
          on a no-load basis (i.e., there are no sales commissions or 12b-1
          fees).

Purchase Restrictions

          1) Because of the risks associated with stock investments, the
             Fund is intended to be a long-term investment vehicle and is
             not designed to provide investors with a  means of speculating
             on short-term stock market movements. Consequently, the
             Fund reserves the right to reject any specific purchase (and
             exchange purchase) request. The Fund also reserves the right to
             suspend the offering of shares for a period of time.

          2) Vanguard will not accept third-party checks to purchase shares
             of the Fund. Please be sure your purchase check is made payable
             to The Vanguard Group.

Additional Investments
          Subsequent investments to regular accounts may be made by mail
          ($100 minimum), wire ($1,000 minimum), exchange from another
          Vanguard Fund account, or Vanguard Fund Express. Subsequent
          investments to Individual Retirement Accounts may be made by mail
          ($100 minimum) or exchange from another Vanguard Fund account. In
          some instances, contributions may be made by wire or Vanguard Fund
          Express. Please call us for more information on these options.

          1. Automatic Reinvestment Option--Both dividends and capital gains
             distributions will be reinvested in additional Fund shares.
             This option will be selected for you automatically unless you
             specify one of the other options.
          2. Cash Dividend Option--Your dividends will be paid in cash and
             your capital gains will be reinvested in additional Fund
             shares.
          3. All Cash Option--Both dividend and capital gains distributions
             will be paid in cash.

          You may change your option by calling our Client Services
          Department (1-800-662-2739).

          In addition, an option to invest your cash dividends and/or
          capital gains distributions in another Vanguard Fund account is
          available. Please call our Client Services Department (1-800-662-
          2739) for information. You may also elect Vanguard Dividend
          Express which allows you to transfer your cash dividends and/or
          capital gains distributions automatically to your bank account.
          Please see "Other Vanguard Services" for more information.
- ----------------------------------------------------------------------------
TAX CAUTION
Investors should ask about the timing of capital gains and
dividend distributions before investing
          Under Federal tax laws, the Fund is required to distribute net
          capital gains and dividend income to Fund shareholders. These
          distributions are made to all shareholders who own Fund shares as
          of the distribution's record date, regardless of how long the
          shares have been owned. Purchasing shares just prior to the record
          date could have a significant impact on your tax liability for the
          year. For example, if you purchase shares immediately prior to the
          record date of a sizable capital gain or income dividend
          distribution, you will be assessed taxes on the amount of the
          capital gain and/or dividend distribution later paid even though
          you owned the Fund shares for just a short period of time. (Taxes
          are due on the distributions even if the dividend or gain is
          reinvested in additional Fund shares.) While the total value of
          your investment will be the same after the distribution--the
          amount of the distribution will offset the drop in the net asset
          value of the shares--you should be aware of the tax implications
          the timing of your purchase may have.

          Prospective investors should, therefore, inquire about potential
          distributions before investing. The Fund's annual capital gains
          distribution normally occurs in December, while income dividends
          are generally paid quarterly in March, June, September and
          December. For additional information on distributions and taxes,
          see the section titled "Dividends, Capital Gains, and Taxes."

IMPORTANT ACCOUNT INFORMATION
Establishing Optional Services
          The easiest way to establish optional Vanguard services on your
          account is to select the options you desire when you complete your
          Account Registration Form. If you wish to add shareholder options
          later, you may need to provide Vanguard with additional
          information and a signature guarantee. Please call our Client
          Services Department (1-800-662-2739) for further assistance.

Signature Guarantees
          For our mutual protection, we may require a signature guarantee on
          certain written transaction requests. A signature guarantee
          verifies the authenticity of your signature and may be obtained
          from banks, brokers and any other guarantors that Vanguard deems
          acceptable. A signature guarantee cannot be provided by a notary
          public.

Certificates
          Share certificates will be issued upon request. If a certificate
          is lost, you may incur an expense to replace it.

Broker/Dealer Purchases
          If you purchase shares in Vanguard Funds through a registered
          broker-dealer or investment adviser, the broker-dealer or adviser
          may charge a service fee.

Cancelling Trades
          The Fund will not cancel any trade (e.g., a purchase, exchange or
          redemption) believed to be authentic, received in writing or by
          telephone, once the trade request has been received.

Electronic Prospectus Delivery
          You may receive a prospectus for the Fund or any of the
          Vanguard Funds in an electronic format. Please call
          1-800-231-7870 for additional information or see "Other Vanguard
          Services--Computer Access." If you elect to do so, you may
          also receive a paper copy of the prospectus by calling
          1-800-662-7447.
- ----------------------------------------------------------------------------
WHEN YOUR ACCOUNT WILL BE CREDITED
          The trade date is the date on which your account is credited. If
          your purchase is made by check, Federal Funds wire, or exchange,
          and is received by the close of the New York Stock Exchange
          (generally 4:00 p.m. Eastern time), your trade date is the day of
          receipt. If your purchase is received after the close of the
          Exchange, your trade date is the next business day. Your shares
          are purchased at the net asset value determined on your trade
          date.

          In order to prevent lengthy processing delays caused by the
          clearing of foreign checks, Vanguard will only accept a foreign
          check which has been drawn in U.S. dollars and has been issued by
          a foreign bank with a U.S. correspondent bank. The name of the
          U.S. correspondent bank must be printed on the face of the foreign
          check.
- ----------------------------------------------------------------------------
SELLING YOUR SHARES
          You may withdraw any portion of the funds in your account by
          redeeming shares  at any time. You generally may initiate a
          redemption request by writing or by telephoning. Your redemption
          proceeds are normally mailed within two business days after the
          receipt of the request in Good Order.

Selling By Telephone
          To sell shares by telephone, you or your pre-authorized
          representative may call our Client Services Department at 1-800-
          662-2739. The proceeds will be sent to you by mail or by wire. In
          addition to the details below, please see "Important Information
          About Telephone Transactions."

          By Mail: Telephone mail redemption is automatically established on
          your account unless you indicate otherwise on your Account
          Registration Form. You may redeem any amount by calling Vanguard.
          The proceeds will be paid to the registered shareholders. Please
          Note: As a protection against fraud, your telephone mail
          redemption privilege will be suspended for 15 calendar days
          following any expedited address change to your account. An
          expedited address change is one that is made by telephone,
          by Vanguard Online, or, in writing, without the signatures
          of all account owners.

          By Wire: Telephone wire redemption must be specifically elected
          for your account. The best time to elect telephone wire redemption
          is at the time you complete your Account Registration Form. If you
          do not presently have telephone wire redemption and wish to
          establish it, please contact our Client Services Department.

          With the wire redemption option, you may withdraw a minimum of
          $1,000 and have the amount wired directly to your bank account.
          Wire redemptions less than $5,000 are subject to a $5 charge
          deducted by Vanguard. There is no Vanguard charge for wire
          redemptions of $5,000 or more. However, your bank may assess a
          separate fee to accept incoming wires.

          A request to change the bank associated with your wire redemption
          option must be received in writing, signed by each registered
          shareholder, and accompanied by a

                                     18
<PAGE>
          voided check or preprinted deposit slip. A signature guarantee is
          required if your bank registration is not identical to your
          Vanguard Fund account registration.
          ------------------------------------------------------------------
Selling By Fund Express
Automatic Withdrawal & Special Redemption
          If you select the Fund Express Automatic Withdrawal option, money
          will be automatically moved from your Vanguard Fund account to
          your bank account according to the schedule you have selected. The
          Special Redemption option lets you move money from your Vanguard
          account to your bank account on an "as needed" basis. To establish
          these Fund Express options, please provide the appropriate
          information on the Account Registration Form. We will send you a
          confirmation of your Fund Express service; please wait two
          weeks before using the service.
          ------------------------------------------------------------------
Selling By Exchange
          You may sell shares of the Fund by making an exchange to another
          Vanguard Fund account. Please see "Exchanging Your Shares" for
          details.
          ------------------------------------------------------------------
Important Redemption Information
          Shares purchased by check or Fund Express may be redeemed at any
          time. However, your redemption proceeds will not be paid until
          payment for the purchase is collected, which may take up to ten
          calendar days.
          ------------------------------------------------------------------
Delivery of Redemption Proceeds
          Redemption requests received by telephone prior to the close of
          regular trading on the New York Stock Exchange (generally 4:00
          p.m. Eastern time) are processed on the day of receipt and the
          redemption proceeds are normally sent on the following business
          day.

          Redemption requests received by telephone after the close of the
          Exchange are processed on the business day following receipt and
          the proceeds are normally sent on the second business day
          following receipt.

          Redemption proceeds must be sent to you within seven days of
          receipt of your request in Good Order, except as described
          above in "Important Redemption Information."

          If you experience difficulty in making a telephone redemption
          during periods of drastic economic or market changes, your
          redemption request may be made by regular or express mail. It will
          be implemented at the net asset value next determined after your
          request has been received by Vanguard in Good Order. The Fund
          reserves the right to revise or terminate the telephone redemption
          privilege at any time.

          The Fund may suspend the redemption right or postpone payment at
          times when the New York Stock Exchange is closed or under any
          emergency circumstances as determined by the United States
          Securities and Exchange Commission.

          If the Board of Trustees determines that it would be detrimental
          to the best interests of the Fund's remaining shareholders to make
          payment in cash, the Fund may pay redemption proceeds in whole or
          in part by a distribution in kind of readily marketable
          securities.
          ------------------------------------------------------------------

Vanguard's Average Cost Statement
          If you make a redemption from a qualifying account, Vanguard will
          send you an Average Cost Statement which provides you with the
          cost and tax basis of the shares you redeemed. Please see
          "Statements and Reports" for additional information.
          ------------------------------------------------------------------
Low Balance Fee and Minimum Account Balance Requirement
          Due to the relatively high cost of maintaining smaller accounts,
          the Fund will automatically deduct a $10 annual fee from non-
          retirement accounts with balances falling below $2,500 ($500 for
          Uniform Gifts/Transfers to Minors Act accounts). This fee
          deduction will occur mid-year, beginning in 1996. The fee
          generally will be waived for investors whose aggregate Vanguard
          assets exceed $50,000.

          In addition, the Fund reserves the right to liquidate any non-
          retirement account that is below the minimum initial investment
          amount of $3,000. If at any time your total investment does not
          have a value of at least $3,000, you may be notified that your
          account is below the Fund's minimum account balance requirement.
          You would then be allowed 60 days to make an additional investment
          before the account is liquidated. Proceeds would be promptly paid
          to the registered shareholder.

          Vanguard will not liquidate your account if it has fallen below
          $3,000 solely as a result of declining markets (i.e., a decline in
          a Fund's net asset value).

Important Exchange Information
          Before you make an exchange, you should consider the following:

          * Please read the Fund's prospectus before making an exchange. For
            a copy and for answers to any questions you may have, call our
            Investor Information Department (1-800-662-7447).
          * An exchange is treated as a redemption and a purchase.
            Therefore, you could realize a taxable gain or loss on the
            transaction.
          * Exchanges are accepted only if the registrations and the
            taxpayer identification numbers of the two accounts are
            identical.
          * The shares to be exchanged must be on deposit and not held in
            certificate form.
          * New accounts are not currently accepted in Vanguard/Windsor
            Fund.
          * The redemption price of shares redeemed by exchange is the net
            asset value next determined after Vanguard has received any
            required documents in Good Order.
             
          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 PRIVILEGE LIMITATIONS
          The Fund's exchange privilege is not intended to afford
          shareholders a way to speculate on short-term movements in the
          market. Accordingly, in order to prevent excessive use of the
          exchange privilege that may potentially disrupt the management of
          the Fund and increase transaction costs, the Fund has established
          a policy of limiting excessive exchange activity.

          Exchange activity generally will not be deemed excessive if
          limited to two substantive exchange redemptions (at least 30 days
          apart) from the Fund during any twelve month period.
          Notwithstanding these limitations, the Fund reserves the right to
          reject any purchase request (including exchange purchases from
          other Vanguard portfolios) that is reasonably deemed to be
          disruptive to efficient portfolio management.
- ----------------------------------------------------------------------------
IMPORTANT INFORMATION ABOUT TELEPHONE TRANSACTIONS
          The ability to initiate redemptions (except wire redemptions) and
          exchanges by telephone is automatically established on your
          account unless you request in writing that telephone transactions
          on your account not be permitted. The ability to initiate wire
          redemptions by telephone will be established on your account only
          if you specifically elect this option in writing.

          To protect your account from losses resulting from unauthorized or
          fraudulent telephone instructions, Vanguard adheres to the
          following security procedures:

          1. Security Check. To request a transaction by telephone, the
             caller must know (i) the name of the Portfolio; (ii) the 10-
             digit account number; (iii) the exact name and address used in
             the registration; and (iv) the Social Security or employer
             identification number listed on the account.

                                     21
<PAGE>
          2. Payment Policy. The proceeds of any telephone redemption by
             mail will be made payable to the registered shareowner and
             mailed to the address of record, only. In the case of a
             telephone redemption by wire, the wire transfer will be made
             only in accordance with the shareowner's prior written
             instructions.

          Neither the Fund nor Vanguard will be responsible for the
          authenticity of transaction instructions received by telephone,
          provided that reasonable security procedures have been followed.
          Vanguard believes that the security procedures described above are
          reasonable, and that if such procedures are followed, you will
          bear the risk of  any losses resulting from unauthorized or
          fraudulent telephone transactions on your account.

                     INVESTMENT OBJECTIVE AND POLICIES
     The following policies supplement the Fund's investment objective and
policies set forth in the Prospectus.

Repurchase Agreements
     The Fund 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 Fund and is unrelated to the interest rate on the underlying instrument.
In these transactions, the securities acquired by the Fund (including
accrued interest earned thereon) must have a total value in excess of the
value of the repurchase agreement and are held by a custodian bank until
repurchased. In addition, the Fund's Board of Trustees 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 the Fund. No more than an aggregate of 15% of the Fund's
assets, at the time of investment, will be invested in repurchase agreements
having maturities longer than seven days and securities subject to legal or
contractual restrictions on resale or for which there are no readily
available market quotations. See "Illiquid Securities" on page 2.

     The use of repurchase agreements involves certain risks. For example,
if the other party to the agreement defaults on its obligation to repurchase
the underlying security at a time when the value of the security has
declined, the Fund may incur a loss upon disposition of the security. If the
other party to the agreement becomes insolvent and subject to liquidation or
reorganization under the Bankruptcy Code or other laws, a court may
determine that the underlying security is collateral for a loan by the Fund
not within the control of the Fund and therefore the realization by the Fund
on such collateral may be automatically stayed. Finally, it is possible that
the Fund 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.

Illiquid Securities
     The Fund may not invest more than 15% of its net assets in illiquid
securities. Illiquid securities are securities that may not be
sold or disposed of in the ordinary course of business within seven business
days at approximately the value at which they are being carried on a Fund's
books. An illiquid security includes repurchase agreements which have a
maturity of longer than seven days, securities which are illiquid by virtue
of the absence of a readily available market, and demand instruments with a
demand notice exceeding seven days. Illiquid securities may include
securities that are not registered under the Securities Act of 1933 (the
"1933 Act"), however, unregistered securities that can be sold to "qualified
institutional buyers" in accordance with Rule 144A under the 1933 Act will
not be considered illiquid so long as it is determined by the Fund's
adviser that an adequate trading market exists for the security.

Futures Contracts and Options
     The Fund may enter into futures contracts, options, and options on
futures contracts for the purpose of remaining fully invested and reducing
transaction costs. Futures contracts provide for the future sale by
one party and purchase by another party of a specified amount of a specific
security at a specified future time and at a specified price. Futures
contracts which are standardized as to maturity date and underlying
financial instrument are traded on national futures exchanges. Futures
exchanges and trading are regulated under the Commodity Exchange Act by the
Commodity Futures Trading Commission ("CFTC"), a U.S. Government Agency.
Assets committed to futures contracts will be segregated at the Fund's
custodian bank to the extent required by law.

     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. 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 that may range upward from less than 5% of
the value of the contract being traded.

The Fund may invest in futures contracts and options
     Although it has no present intention to do so, the Fund may utilize
equity futures contracts and options to a limited extent. Specifically, the
Fund may enter into futures contracts provided that not more than 5% of its
assets are required as a futures contract deposit; in addition, the Fund may
enter into futures contracts and options transactions only to the extent
that obligations under such contracts or transactions represent not more
than 20% of the Fund's assets.

     Futures contracts and options may be used for several reasons: to
maintain cash reserves while simulating full investment, to facilitate
trading, to reduce transactions costs, or to seek higher investment returns
when a futures contract is priced more attractively than the underlying
equity security or index. Although futures contracts and options may
be used as leveraged instruments, the Fund will not use futures contracts or
options transactions to leverage its assets.

     For example, in order to remain fully invested in stocks, while
maintaining liquidity to meet potential shareholder redemptions, the Fund
may invest a portion of its assets in a stock index futures contract.
Because futures contracts only require a small initial margin deposit, the
Fund would then be able to maintain a cash reserve to meet potential
redemptions, while at the same time remaining fully invested. Also, because
the transaction costs of futures contracts and options may be lower
than the costs of investing in stocks directly, it is expected that the use
of futures contracts and options may reduce the Fund's total
transaction costs.

Futures contracts and options pose certain risks
     The primary risks associated with the use of futures contracts and
options are: (i) imperfect correlation between the change in market value of
the stocks held by the Fund and the prices of futures and options; and (ii)
possible lack of a liquid secondary market for a futures contract and the
resulting inability to close a futures position prior to its maturity date.
The risk of imperfect correlation will be minimized by investing only in
those contracts whose price fluctuations are

                                    B-2
<PAGE>
expected to resemble those of the Fund's underlying securities. The risk
that the Fund will be unable to close out a futures position will be
minimized by entering into such transactions on a national exchange with an
active and liquid secondary market.

     After a futures contract position is opened, the value of the contract
is marked to the market daily. If the futures contract price changes
to the extent that the margin on deposit does not satisfy margin
requirements, payment of additional "variation" margin will be required.
Conversely, change in the contract value may reduce the required margin,
resulting in a repayment of excess margin to the contract holder. Variation
margin payments are made to and from the futures broker for as long as the
contract remains open. The Fund expects to earn interest income on its
margin deposits.

     Traders in futures contracts may be broadly classified as either
"hedgers" or "speculators." Hedgers use the futures markets primarily to
offset unfavorable changes in the value of securities otherwise held for
investment purposes or expected to be acquired by them. Speculators are less
inclined to own the securities underlying the futures contracts which they
trade, and use futures contracts with the expectation of realizing profits
from fluctuations in the value of the underlying securities. The Fund
intends to use futures contracts only for bona fide hedging purposes.

     Regulations of the CFTC applicable to the Fund require that all of its
futures transactions constitute bona fide 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 interest rate
futures contracts it holds. The inability to close options and futures
positions also could have an adverse impact on the Fund's ability to
effectively hedge. 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 option. Additionally, investments in
futures contracts and options involve the risk that the investment advisers
will incorrectly predict stock market and interest rate trends.

     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

                                    B-3
<PAGE>
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 option.

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
     The Fund is required for Federal income tax purposes to recognize as
income for each taxable year its net unrealized gains and losses on futures
contracts held as of the end of the year as well as those actually realized
during the year. In most cases, any gain or loss recognized with respect to
a futures contract is considered to be 60% long-term capital gain or loss
and 40% short-term capital gain or loss, without regard to the holding
period of the contract. Furthermore, sales of futures contracts which are
intended to hedge against a change in the value of securities held by the
Fund may affect the holding period of such securities and, consequently, the
nature of the gain or loss on such securities upon disposition. The Fund may
be required to defer the recognition of losses on futures contracts to the
extent of any unrecognized gains on related positions held by the Fund.

     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, and gains from
the sale of securities or foreign currencies, or other income derived with
respect to its business of investing in such securities or currencies. In
addition, gains realized on the sale or other disposition of securities held
for less than three months must be limited to less than 30% of the 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 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 payments.

Lending of Securities
     The Fund may lend its portfolio securities on a short-term or a long-
term basis to qualified institutional investors who need to borrow
securities in order to complete certain transactions, such as covering short
sales, avoiding failures to deliver securities or completing arbitrage
operations. By lending its portfolio securities, the Fund attempts to
increase its income through the receipt of interest on the loan. Any gain or
loss in the market price of the securities loaned that might occur during the
term of the loan would be for the account of the Fund. The Fund may lend its
portfolio securities to qualified brokers, dealers, banks or other financial
institutions, so long as the terms and the structure of such loans are not

                                    B-4
<PAGE>
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 Fund at any time, and (d) the Fund receive reasonable
interest on the loan (which may include the Fund's investing any cash
collateral in interest bearing short-term investments), any distributions on
the loaned securities and any increase in their market value. The Fund will
accept only cash as collateral for its loaned securities and will not lend
portfolio securities if, as a result, the aggregate of such loans exceeds
10% of the value of the Fund's total assets. Loan arrangements made by the
Fund will comply with all other applicable regulatory requirements,
including the rules of the New York Stock Exchange, which rules presently
require the borrower, after notice, to redeliver the securities within the
normal settlement time of three 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 Trustees.
Since income derived from lending portfolio securities is not qualifying
income for the purpose of the 70% intercorporate dividends received
deduction under Federal tax laws, the Fund will limit such activity in
accordance with its objective of maximizing dividend income which qualifies
for the dividends deduction.

     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 Trustees (Directors).

                           YIELD AND TOTAL RETURN
     The yield of the Fund for the 30-day period ended October 31,
1996 was +7.21%.

     The average annual total return of the Fund for the one-, five- and
ten-year periods ending October 31, 1996 was +8.04%, +9.52%
and +8.73%, respectively. Total return is computed by finding the
average compounded rates of return over the one-, five- and ten-year periods
set forth above that would equate an initial amount invested at the
beginning of the periods to the ending redeemable value of the investment.

                             PURCHASE OF SHARES
     The purchase price of shares of the Fund is the net asset value next
determined after the order is received. The net asset value is calculated as
of the close of the New York Stock Exchange on each day the Exchange is open
for business. An order received prior to the close of the Exchange will be
executed at the price computed on the date of receipt; and an order received
after the close of the Exchange will be executed at the price computed on
the next day the Exchange is open.

     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, and (iii)
to reduce or waive the minimum investment for or any other restrictions on
initial and subsequent investments for certain fiduciary accounts such as
employee benefit plans or under circumstances where certain economies can be
achieved in sales of the Fund's shares.

                            REDEMPTION OF SHARES
     The Fund may suspend redemption privileges or postpone the date of
payment (i) during any period that the New York Stock Exchange is closed, or
trading on the Exchange is restricted as determined by the Securities and
Exchange Commission (the "Commission"), (ii) during any period when an
emergency exists as defined by the rules of the Commission as a result of
which it is not reasonably practicable for the Fund to dispose of securities
owned by it, or fairly to determine the value of its assets, and (iii) for
such other periods as the Commission may permit.

     The Fund has made an election with the Commission to pay in cash all
redemptions requested by any shareholder of record limited in amount during
any 90-day period to the lesser of $250,000 or 1% of the net assets of the
Fund at the beginning of such period. Such commitment is irrevocable without
the prior approval of the Commission. Redemptions in excess of the above
limits may be paid, in whole or in part, in investment securities or in
cash, as the Trustees may deem advisable; however, payment will be made wholly
in cash unless the Trustees believe that economic or market conditions

                                    B-5
<PAGE>
exist which would make such a practice detrimental to the best interests of
the Fund. If redemptions are paid in investment securities, such securities
will be valued as set forth in the Prospectus under "The Fund's Share Price"
and a redeeming shareholder would normally incur brokerage expenses if he
converted these securities to cash.

     No charge is made by the Fund for redemptions, except for wire
withdrawals in amounts less than $5,000 which are subject to a $5.00 charge
which will be deducted from the payment issued to you. Any redemption may be
more or less than the shareholder's cost depending on the market value of
the Fund's portfolio securities.

     Signature Guarantees -- To protect your account, the Fund and Vanguard
from fraud, signature guarantees are required for certain redemptions.
Signature guarantees enable the Fund to verify the identity of the person
who has authorized a redemption from your account. Signature guarantees are
required in connection with: (1) all redemptions, regardless of the
amount involved, when the proceeds are to be paid to someone other than the
registered owner(s) and/or registered address; and (2) share transfer
requests. These requirements are not applicable to redemptions in Vanguard's
prototype retirement plans except in connection with: (1) distributions made
when the proceeds are to be paid to someone other than the plan participant;
(2) certain authorizations to effect exchanges by telephone; and (3) when
proceeds are to be wired. These requirements may be waived by the Fund in
certain instances.

     Signature guarantees may be obtained from a bank, broker or any other
guarantor institution that Vanguard deems acceptable. Notaries public are
not acceptable guarantors.

     The signature guarantees must appear either: (1) on the written request
for redemption; (2) on a separate instrument for assignment ("stock power")
which should specify the total number of shares to be redeemed; or (3) on
all stock certificates tendered for redemption and, if shares held by the
Fund are also being redeemed, on the letter or stock power.

                           INVESTMENT LIMITATIONS
     The Fund is subject to the following limitations which may not be
changed without the approval of at least a majority of the outstanding
voting securities of the Fund. The Fund will not:

     (1) Borrow money, except that the Fund may borrow from banks (or
through reverse repurchase agreements), for temporary or emergency (not
leveraging) purposes, including the meeting of redemption requests which
might otherwise require the untimely disposition of securities, in an amount
not exceeding 15% of the value of the Fund's net assets (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 Fund's net assets, the Fund will not make any additional
investments;

     (2) With respect to 75% of the value of its total assets, purchase the
securities of any issuer (except obligations of the United States government
and its instrumentalities) if, as a result, the Fund would hold more than
10% of the outstanding voting securities of the issuer, or more than 5% of
the value of the Fund's total assets would be invested in the securities of
such issuer;

     (3) Invest in companies for the purpose of exercising control;

     (4) Invest in securities of other investment companies, except as they
may be acquired as a part of a merger, consolidation or acquisition of
assets or otherwise to the extent permitted by Section 12 of the 1940 Act.
The Fund will invest only in investment companies which have investment
objectives and investment policies consistent with those of the Fund;

     (5) Engage in the business of underwriting securities issued by other
persons, except to the extent that the Fund may technically be deemed to be
an underwriter under the Securities Act of 1933, as amended, in disposing of
portfolio securities;

     (6) Purchase or otherwise acquire any security (including the Fund's
investment in The Vanguard Group, Inc.) if, as a result, more than 15% of
its net assets would be invested in securities that are illiquid;

     (7) Purchase or sell real estate although it may purchase and sell
securities of companies which deal in real estate or interests therein;

     (8) Purchase or sell commodities or commodity contracts, except that
the Fund may invest in stock futures contracts, stock options and options on
stock futures contracts to the extent that not more than 5% of its assets
are required as

                                    B-6
<PAGE>
deposit to secure obligations under such contracts and not more than 20% of
the Funds assets are invested in futures contracts and options at any time;

     (9) Write, or invest in, put, call, straddle, or spread option
contracts (except as described above in investment limitation No. 8) or
invest in interests in oil, gas, or other mineral exploration or development
programs;

     (10) Purchase securities on margin or sell any securities short (except
as described above in investment limitation No. 8);

     (11) Make loans except (i) by purchasing bonds, debentures or similar
obligations (including repurchase agreements) which are either publicly
distributed or customarily purchased by institutional investors, and (ii) as
provided under "Lending of Securities" (page 4); and

     (12) The Fund, with the exception of the electric and/or gas industries
in which it may invest a majority of its assets, will not concentrate its
investments in any other particular industry, by investing more than 25% of
the value of its total assets taken at market value in securities of issuers
all of which conduct their principal business activities in the same
industry.

     These limitations are considered at the time investment securities are
purchased. Notwithstanding these limitations the Fund may own all or any
portion of the securities of, or make loans to, or contribute to the costs
or other financial requirements of any company which will be wholly owned by
the Fund and one or more other investment companies and is primarily engaged
in the business of providing, at-cost, management, administrative or related
services to the Fund and other investment companies. See "The Vanguard
Group" on page 9.

     Although not fundamental policies subject to shareholder vote, as long
as the Fund's shares are registered for sale in certain states, it will not

     (1) Invest more than 5% of the value of the total assets of the Fund at
the time of investment in the securities of any issuers which have records
of less than three years' continuous operation, including the operation of
any predecessor, but this limitation does not apply to securities issued or
guaranteed as to interest and principal by the United States Government or
its agencies or instrumentalities; or

     (2) Purchase or retain any security of an issuer if an officer
or director of the Fund, or its investment adviser owns beneficially more
than 1/2% of the shares or securities of such issuer and all such directors
and officers owning more than 1/2% of such shares or securities together own
more than 5% of such shares or securities.

The Vanguard Group
     Vanguard Preferred Stock Fund is a member of The Vanguard Group of
Investment Companies. Through their jointly-owned subsidiary, The Vanguard
Group, Inc. ("Vanguard"), the Fund and the other Funds in the Group obtain
at-cost virtually all of their corporate management, administrative and
distribution services. Vanguard also provides investment advisory services
on an at-cost basis to a number of the Vanguard Funds.

     Vanguard employs a supporting staff of management and administrative
personnel needed to provide the requisite services to the Funds and also
furnishes the Funds with necessary office space, furnishings and equipment.
Each Fund pays its share of Vanguard's total expenses which are allocated
among the Funds under methods approved by the Board of Trustees (Directors)
of each Fund. In addition, each Fund bears its own direct expenses, such as
legal, auditing and custodian fees.

     The Vanguard Group adheres to a Code of Ethics established pursuant to
Rule 17j-1 under the Investment Company Act of 1940. The Code is
designed to prevent unlawful practices in connection with the purchase or
sale of securities by persons associated with Vanguard. Under Vanguard's
Code of Ethics certain Officers and employees of Vanguard who are
considered access persons are permitted to engage in personal securities
transactions. However, such transactions are subject to procedures and
guidelines substantially similar to those recommended by the mutual fund
industry and approved by the U.S. Securities and Exchange Commission.

     The Vanguard Group was established and operates under a Funds' Service
Agreement which was approved by the shareholders of each of the Funds. The
amounts which each of the Funds has invested are adjusted from time to time
in order to maintain the proportionate relationship between each Fund's
relative net assets and its contribution to Vanguard's capital. The Funds'
Service Agreement provides as follows: (1) each Vanguard Fund may invest a
maximum of .40% of its current net assets in Vanguard, and (2) there are no
restrictions on the maximum aggregate cash investment that the Vanguard
Funds may make in Vanguard. At October 31, 1996, the Fund had
contributed capital of $27,000 to Vanguard, representing 0.1%
of Vanguard's capitalization.

Management
     Corporate management and administrative services include: (1) executive
staff; (2) accounting and financial; (3) legal and regulatory; (4)
shareholder account maintenance; (5) monitoring and control of custodian
relationships; (6) shareholder reporting; and (7) review and evaluation of
advisory and other services provided to the Funds by third parties. During
the fiscal year ended October 31, 1996, the Fund's share of
Vanguard's actual net costs of operation relating to management and
administrative services (including transfer agency) totaled approximately
$585,000.

Distribution
     Vanguard provides all distribution and marketing activities for the
Funds in the Group. Vanguard Marketing Corporation, a wholly-owned
subsidiary of The Vanguard Group, Inc., acts as Sales Agent for shares of
the Funds, in connection with any sales made directly to investors in the
states of Florida, Missouri, New York, Ohio, Texas and such other states as
it may be required.

     The principal distribution expenses are for advertising, promotional
materials and marketing personnel. Distribution services may also include
organizing and offering to the public, from time to time, one or more new
investment companies which will become members of the Group. The Directors
and Officers of Vanguard determine the amount to be spent annually on
distribution activities, the manner and amount to be spent on each Fund, and
whether to organize new investment companies.

     One half of the distribution expenses of a marketing and promotional
nature is allocated among the Funds based upon their relative net assets.
The remaining one half of these expenses is allocated among the Funds based
upon each Fund's sales for the preceding 24 months relative to the total
sales of the Funds as a Group, provided, however, that no Fund's aggregate
quarterly rate of contribution for distribution expenses of a marketing and
promotional nature shall exceed 125% of the average distribution expense
rate for the Group, and that no Fund shall incur annual distribution
expenses in excess of .20 of 1% of its average month-end net assets.
During the fiscal year ended October 31, 1996, the Fund paid
approximately $65,000 of the Group's distribution and marketing
expenses, which represented an effective annual rate of .02 of 1% of
the Fund's average net assets.

Remuneration of Trustees and Officers
     The Fund pays each Trustee who is not also an Officer an annual fee
plus travel and other expenses incurred in attending Board meetings. The
Fund's Officers and employees are paid by Vanguard which, in turn, is
reimbursed by the Fund, and each other Fund in the Group, for its
proportionate share of Officers' and employees' salaries and retirement
benefits. The Fund's proportionate share of remuneration paid by Vanguard
(and reimbursed by the Fund) during the 1996 fiscal year to all
Officers of the Fund, as a group, was approximately $8,867.

     Upon retirement, Trustees who are not Officers are paid an annual fee
based upon the number of years of service on the Board. The fee is equal to
$1,000 for each year of service on the Board up to a maximum of fifteen
years. Under its retirement plan, Vanguard contributes annually an amount
equal to 10% of each eligible Officer's annual compensation plus 5.7% of
that part of the eligible Officer's compensation during the year, if
any, that exceeds the Social Security Taxable Wage Base then in effect.
Under its thrift plan, all eligible Officers are permitted to make pre-tax
contributions in an amount equal to 4% of total compensation which are
matched by Vanguard on a 100% basis. The Fund's proportionate share of
retirement contributions made by Vanguard under its retirement and thrift
plans on behalf of all eligible Officers of the Fund, as a group, during the
1996 fiscal year was approximately $150.
    
     The following table provides detailed information with respect to the

                        INVESTMENT ADVISORY SERVICES
     The Fund employs Wellington Management Company, LLP (the
"Adviser") under an investment advisory agreement dated August 1, 1996 to
manage the investment and reinvestment of the assets of the Fund and to
continuously review, supervise and administer the Fund's investment program.
The Adviser discharges its responsibilities subject to the control of the
Officers and Trustees of the Fund.

     The Fund pays the Adviser an advisory fee at the end of each fiscal
quarter, calculated by applying a quarterly rate, based on the following
annual percentage rates, to the Fund's average month-end net assets for the
quarter:

              Net Assets                                Rate
              ----------                               ----
          First $200 million ......................   .150%
          Next $200 million .......................   .100%
          Assets in excess of $400 million ........   .075%

     During the fiscal years ended October 31, 1994, 1995 and
1996, the Fund paid advisory fees of $817,000, $706,669, and
$394,000, respectively. In 1994, 1995 and through July 31, 1996, fees were
paid under an advisory agreement that provided for a higher rate of
fees.

     The present agreement continues until July 31, 1998 and is renewable
thereafter, for successive one-year periods, only if each renewal is
specifically approved by a vote of the Fund's Board of Trustees, including
the affirmative votes of a majority of the Trustees who are not parties to
the contract or "interested persons" (as defined in the Investment Company
Act of 1940) of any such party, cast in person at a meeting called for the
purpose of considering such approval.

     The Fund's Board of Trustees 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.

     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, which shall include the information
concerning the adviser that would have normally been included in a proxy
statement.

Description of the Adviser
     Wellington Management Company, 75 State Street, Boston, MA 02109, is a
Massachusetts limited liability partnership, of which the following
persons are managing partners: Robert W. Doran, Duncan M. McFarland and John
R. Ryan.

                           PORTFOLIO TRANSACTIONS
     The investment advisory agreement authorizes the Adviser (with the
approval of the Fund's Board of Trustees) to select the brokers or dealers
that will execute the purchases and sales of portfolio securities for the
Fund and directs the Adviser to use its best efforts to obtain the best
available price and most favorable execution as to all transactions for the
Fund. The Adviser has undertaken to execute each investment transaction at a
price and commission which provides the most favorable total cost or
proceeds reasonably obtainable under the circumstances.

     In placing portfolio transactions, the 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 Adviser. The
Adviser considers such information useful in the performance of its
obligations under the agreement but is unable to determine the amount by
which such services may reduce its expenses.

     The investment advisory agreement also incorporates 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
Trustees, the Adviser may cause the Fund to pay a

                                    B-11
<PAGE>
broker-dealer which furnishes brokerage and research services a higher
commission than that which might be charged by another broker-dealer for
effecting the same transaction; provided that such commission is deemed
reasonable in terms of either that particular transaction or the overall
responsibilities of the Adviser to the Fund and the other Funds in the
Group.

     Currently, it is the Fund's policy that the 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. The 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 Adviser and/or the Fund. However,
the 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 through such
firms. However, the Fund may place portfolio orders with qualified broker-
dealers who recommend the Fund to other clients, or who act as agent in the
purchase of the Fund's shares for their clients, and may, when a number of
brokers and dealers can provide comparable best price and execution on a
particular transaction, consider the sale of Fund shares by a broker or
dealer in selecting among qualified broker-dealers.

     During the fiscal years ended October 31, 1994, 1995 and
1996 the Fund paid $6,726, $509 and $7,554 in
brokerage commissions, respectively.

     Some securities considered for investment by the Fund may also be
appropriate for other Funds and/or clients served by the Adviser. If
purchase or sale of securities consistent with the investment policies of
the Fund and one or more of these other Funds or clients served by the
Adviser are considered at or about the same time, transactions in such
securities will be allocated among the several Funds and clients in a manner
deemed equitable by the Adviser.

                            GENERAL INFORMATION
Description of Shares and Voting Rights
     The Fund was originally organized as a Maryland corporation in 1975. On
November 12, 1984 the Fund was reorganized into a Pennsylvania business
trust which was created solely for that purpose. The Declaration of Trust
permits the Trustees to issue an unlimited number of shares of beneficial
interest, without par value.

     The shares of the Fund are fully paid and non-assessable, except as set
forth under "Shareholder and Trustee Liability," and have no preference as
to conversion, exchange, dividends, retirement or other features. The shares
have no pre-emptive rights. The shares have non-cumulative voting rights,
which means that the holders of more than 50% of the shares voting for the
election of Trustees can elect 100% of the Trustees if they choose to do so.
A shareholder is entitled to one vote for each full share held (and a
fractional vote for each fractional share held), then standing in his name
on the books of the Fund. On any matter submitted to a vote of shareholders,
all shares of the Fund then issued and outstanding and entitled to vote,
irrespective of the class, shall be voted in the aggregate and not by class:
except (i) when required by the Investment Company Act of 1940, shares shall
be voted by individual class; and (ii) when the matter does not affect any
interest of a particular class, then only shareholders of the affected class
or classes shall be entitled to vote thereon.

     The Fund will continue without limitation of time, provided however
that:

     1) Subject to the majority vote of the holders of shares of the Fund
        outstanding, the Trustees may sell or convert the assets of the Fund
        to another investment company in exchange for shares of such
        investment company, and distribute such shares, ratably among the
        shareholders of the Fund; and

     2) Subject to the majority vote of shares of the Fund outstanding, the
        Trustees may sell and convert into money the assets of the Fund and
        distribute such assets ratably among the shareholders of the Fund.

     Upon completion of the distribution of the remaining proceeds or the
remaining assets of the Fund as provided in paragraphs 1) and 2) above, the
Fund shall terminate and the Trustees shall be discharged of any and all
further liabilities and duties hereunder and the right, title and interest
of all parties shall be cancelled and discharged.

                                    B-12
<PAGE>
Shareholder and Trustee Liability
     Under Pennsylvania law, shareholders of a trust may, under certain
circumstances, be held personally liable as partners for the obligations of
the Trust. Therefore, the Declaration of Trust contains an express
disclaimer of shareholder liability for acts or obligations of the Fund and
requires that notice of such disclaimer be given in each agreement,
obligation, or instrument entered into or executed by the Fund or the
Trustees. The Declaration of Trust provides for indemnification out of the
Fund property of any shareholder held personally liable for the obligations
of the Fund. The Declaration of Trust also provides that the Fund shall,
upon request, assume the defense of any claim made against any shareholder
for any act or obligation of the Fund and satisfy any judgment thereon.
Thus, the risk of a shareholder incurring financial loss on account of
shareholder liability is limited to circumstances in which the Fund itself
would be unable to meet its obligations. The Trustees and officers of the
Fund believe that, in view of the above, the risk of personal liability to
shareholders is remote.

     The Declaration of Trust further provides that the Trustees will not be
liable for errors of judgment or mistakes of fact or law, but nothing in the
Declaration of Trust protects a Trustee against any liability to which he
would otherwise be subject by reason of willful misfeasance, bad faith,
gross negligence, or reckless disregard of the duties involved in the
conduct of his office.

             APPENDIX -- DESCRIPTION OF PREFERRED STOCK RATINGS
     Excerpts from Moody's Investor Service, Inc. description of its
four highest preferred stock ratings: aaa -- considered to be a top-quality
preferred stock. This rating indicates good asset protection and the least
risk of dividend impairment within the universe of preferred stocks; aa --
considered a high-grade preferred stock. This rating indicates that there is
reasonable assurance that earnings and asset protection will remain
relatively well maintained in the foreseeable future; a -- considered to be
an upper-medium grade preferred stock. While risks are judged to be somewhat
greater than in the aaa and aa classifications, earning and asset protection
are, nevertheless, expected to be maintained at adequate levels; baa --
considered to be lower-medium grade, neither highly protected nor poorly
secured. Earnings and asset protection appear adequate at present but may be
questionable over any great length of time.

are independent of Standard & Poor's bond ratings, however, in the sense
that they are not necessarily graduated downward from the rankings accorded
the issuing company's debt. They represent a considered judgment of the
relative security of dividends, and -- what is thereby implied -- the
prospective yield stability of the stock. The four highest ratings are AAA
- -- Prime; AA -- High Grade; A -- Sound; BBB -- Medium Grade.
