RISK               Investors in the Fund are exposed to four types of risk from
CHARACTERISTICS    fixed income  securities.  (1)  INTEREST RATE  RISK  is  the
                   potential  for fluctuations  in bond prices  due to changing
                   interest rates.  (2)  INCOME RISK  is  the potential  for  a
                   decline  in  a  Portfolio's  income  due  to  falling market
                   interest rates. (3)  CREDIT RISK is  the possibility that  a
                   bond  issuer  will fail  to make  timely payments  of either
                   interest or principal  to a Portfolio.  (4) PREPAYMENT  RISK
                   (for mortgage-backed securities) or CALL RISK (for corporate
                   bonds)  is the  likelihood that,  during periods  of falling
                   interest rates, securities with  high stated interest  rates
                   will be prepaid (or "called") prior to maturity, requiring a
                   Portfolio to invest the proceeds at generally lower interest
                   rates.

                   The following chart summarizes interest rate, credit, income
                   and  prepayment/call risks for each  of the eight Portfolios
                   of the Fund offered by  this Prospectus. As shown,  interest
                   rate risk should be low for the three short-term Portfolios,
                   moderate  for  the three  intermediate-term  Portfolios, and
                   high for the two long-term Portfolios.               PAGE 16

THE VANGUARD       The Fund is  a member  of The Vanguard  Group of  Investment
GROUP              Companies,  a  group  of  32  investment  companies  with 78
                   distinct investment portfolios and total assets in excess of
                   $120 billion.  The  Vanguard  Group,  Inc.  ("Vanguard"),  a
                   subsidiary jointly owned by the Vanguard funds, provides all
                   corporate   management,  administrative,  distribution,  and
                   shareholder accounting services on  an at-cost basis to  the
                   funds  in  the  Group.  As  a  result,  Vanguard's operating
                   expenses are substantially  lower than those  of the  mutual
                   fund  industry.                                      PAGE 24

INVESTMENT         Wellington Management Company  serves as investment  adviser
ADVISERS           to  the GNMA and  Long-Term Corporate Portfolios. Vanguard's
                   Fixed Income Group provides investment advisory services  on
                   an at-cost basis to the three Short-Term Portfolios, the two
                   Intermediate-Term Portfolios and the Long-Term U.S. Treasury
                   Portfolio.                                          PAGE  24
- -------------------------------------------------------------------------------
DIVIDEND POLICY    Each Portfolio declares a  dividend each business day  based
                   on  its  ordinary income.  Dividends are  paid on  the first
                   business day of  each month.  Net capital  gains (excess  of
                   long-and  short-term capital gains  over capital losses), if
                   any, will  be  distributed annually.  Dividend  and  capital
                   gains distributions may be received in cash or reinvested in
                   additional shares.                                    PAGE27
- -------------------------------------------------------------------------------
TAXES              Dividends  paid  by  the  Fund's  Portfolios  are  generally
                   subject to federal, state  and local income taxes.  However,
                   it  is  expected  that  most  of  the  income  paid  by  the
                   Short-Term, Intermediate-Term, and  Long-Term U.S.  Treasury
                   Portfolios,  and a meaningful portion of the income from the
                   Short-Term Federal Portfolio, will  be attributable to  U.S.
                   Treasury  and  other "direct"  Government  obligations. Such
                   income may be exempt from  state and local taxes,  depending
                   on state and local tax laws. Any capital gains distributions
                   from  a Portfolio are subject to federal income tax, as well
                   as  any  applicable  state  and  local  taxes.  A  sale   of
                   shares--whether   by   outright   redemption,   checkwriting
                   redemption or an exchange--is a taxable event and may result
                   in a capital gain or loss.                            PAGE27
- -------------------------------------------------------------------------------
PURCHASING SHARES  You may  purchase shares  by mail,  wire, or  exchange  from
                   another  Vanguard Portfolio. The  minimum initial investment
                   is $3,000  per  Portfolio ($500  for  Individual  Retirement
                   Accounts   and   Uniform  Gifts/Transfers   to   Minors  Act
                   accounts); the minimum for  subsequent investments is  $100.
                   There  are  no  sales  commissions or  12b-1  fees.  PAGE 30
- -------------------------------------------------------------------------------
SELLING SHARES     You may redeem shares of  each Portfolio by mail,  telephone
                   or  check. Telephone redemption proceeds  may be received by
                   mail or by wire. There is no charge for redemptions,  except
                   for wire withdrawals under $5,000, which are subject to a $5
                   charge.  (Your bank may also impose  a fee upon receipt of a
                   wire.)  Each  Portfolio's   share  price   is  expected   to
                   fluctuate, and at the time of redemption may be more or less
                   than at the time of initial purchase, resulting in a gain or
                   loss.   PAGE 34

YIELD AND TOTAL     From  time to time  a Portfolio may  advertise its yield and
RETURN              total return. BOTH YIELD AND TOTAL RETURN FIGURES ARE  BASED
                    ON  HISTORICAL  EARNINGS AND  ARE  NOT INTENDED  TO INDICATE
                    FUTURE PERFORMANCE. The "total return" of a Portfolio refers
                    to the average annual compounded rates of return over  one-,
                    five-and  ten-year periods or for  the life of the Portfolio
                    (as stated  in  the  advertisement)  that  would  equate  an
                    initial  amount invested at the beginning of a stated period
                    to the ending redeemable  value of the investment,  assuming
                    the   reinvestment  of   all  dividend   and  capital  gains
                    distributions.

                    The "30-day yield" of a Portfolio is calculated by  dividing
                    net  investment  income  per share  earned  during  a 30-day
                    period by the net asset value  per share on the last day  of
                    the  period.  Net  investment income  includes  interest and
                    dividend income earned on the Portfolio's securities; it  is
                    net  of  all  expenses and  all  recurring  and nonrecurring
                    charges that have been applied to all shareholder  accounts.
                    The  yield  calculation assumes  that net  investment income
                    earned over 30 days is compounded monthly for six months and
                    then annualized. Methods used to calculate advertised yields
                    are standardized  for  all  stock  and  bond  mutual  funds.
                    However,  these methods  differ from  the accounting methods
                    used by a Portfolio to  maintain its books and records,  and
                    so  the advertised  30-day yield  may not  fully reflect the
                    income paid to your own account or the yield reported in the
                    Portfolio's Reports to Shareholders.

                    Additionally, a  Portfolio may  compare its  performance  to
                    that  of the Lehman Aggregate  Bond Index, and may advertise
                    its duration,  a measure  of  a Portfolio's  sensitivity  to
                    interest rate changes.

INVESTMENT          The  Fund is an open-end diversified investment company. The
OBJECTIVE           objective of the Fund  is to provide  investors with a  high
                    level  of current income consistent  with the maintenance of
                    principal and liquidity.
THE FUND SEEKS TO
PROVIDE A HIGH      The Fund consists of nine distinct Portfolios, each of which
LEVEL               invests  in  fixed   income  securities  within   prescribed
OF CURRENT INCOME   maturity  and quality standards. There  is no assurance that
                    the Fund will achieve its stated objective.

                    The investment objective for the Fund is not fundamental and
                    so  may  be  changed  by  the  Board  of  Directors  without
                    shareholder  approval. Any  such change could  result in the
                    Fund  having  investment   objectives  different  from   the
                    objectives which a shareholder considered appropriate at the
                    time  of investment in the Fund. However, shareholders would
                    be notified  prior  to any  material  change in  the  Fund's
                    objective.
- --------------------------------------------------------------------------------
INVESTMENT          While  all of the  Fund's Portfolios invest  in fixed income
POLICIES            securities, the individual Portfolios vary substantially  in
                    terms  of the type, credit  quality, and average maturity of
                    the securities in  which they  invest. The  Fund is  managed
                    without regard to tax ramifications.
                    IMPORTANT  NOTE:  Five  of  the  Portfolios  invest  in U.S.
                    Treasury or U.S.  Government agency  securities to  minimize
                    credit   risk.  Examples  of  the  Government  agencies  and
                    instrumentalities whose securities may be purchased by these
                    Portfolios  include   the   Federal   Home   Loan   Mortgage
                    Corporation,  the  Small Business  Administration,  the Gov-
                    ernment Export  Trust and  the Overseas  Private  Investment
                    Corporation.  Government securities may be backed by (i) the
                    full faith  and  credit  of  the  United  States;  (ii)  the
                    particular  Government agency's  ability to  borrow directly
                    from the Treasury;  (iii) some other  type of United  States
                    support;  or (iv) the credit of the issuing agency, only. As
                    described in the investment  policies set forth below,  each

                    securities is required to  invest a specified percentage  of
                    its assets in securities backed by the full faith and credit
                    of  the  United States.  WHILE  U.S. TREASURY  OR GOVERNMENT
                    AGENCY SECURITIES  PROVIDE  SUBSTANTIAL  PROTECTION  AGAINST
                    CREDIT  RISK, THEY  DO NOT  PROTECT INVESTORS  AGAINST PRICE
                    CHANGES DUE TO CHANGING INTEREST RATES. THE MARKET VALUES OF
                    GOVERNMENT SECURITIES ARE NOT GUARANTEED AND WILL FLUCTUATE.
                    See "Investment Risks" for  additional information on  these
                    and other important risks.

THREE PORTFOLIOS    Three Portfolios of the Fund invest in short-term bonds. The
INVEST IN           SHORT-TERM  U.S. TREASURY PORTFOLIO invests  at least 85% of
SHORT-TERM          its assets in short-term securities backed by the full faith
BONDS               and credit of the U.S. Government. Also, at least 65% of the
                    Portfolio's assets will be invested in U.S. Treasury  bills,
                    notes  and bonds. In  an effort to  minimize fluctuations in
                    market value,  the  Short-Term U.S.  Treasury  Portfolio  is
                    expected  to  maintain  a  dollar-weighted  average maturity
                    between one and three years.
                    The balance  of  the Short-Term  U.S.  Treasury  Portfolio's
                    assets  may be invested in  U.S. Treasury or U.S. Government
                    agency securities,  as  well  as  in  repurchase  agreements
                    collateralized  by such  securities. The  Portfolio may also
                    invest in  bond (interest  rate) futures  and options  to  a
                    limited  extent.  See  "Implementation  of  Policies"  for a
                    description of these investment practices of the Portfolio.
                    The SHORT-TERM FEDERAL PORTFOLIO  invests primarily in  U.S.
                    Government  agency  securities, which  are  debt obligations
                    issued or guaranteed by agencies or instrumentalities of the
                    U.S. Government. Such "agency" securities may not be  backed
                    by  the "full faith and credit"  of the U.S. Government. The
                    Portfolio may also  invest in U.S.  Treasury securities,  as
                    well  as  in  repurchase agreements  collateralized  by U.S.
                    Treasury or U.S. Government agency securities. In an  effort
                    to  minimize  fluctuations in  market value,  the Short-Term
                    Federal  Portfolio  is   expected  to   maintain  a   dollar
                    weighted-average   maturity  between  1  and  3  years.  See
                    "Implementation of  Policies"  for a  description  of  these
                    investment practices of the Portfolio.
                    The  SHORT-TERM CORPORATE PORTFOLIO invests in the following
                    investment grade fixed income securities:
                    (1)  Short-term   and   intermediate-term   corporate   debt
                        securities;
                    (2) U.S. Treasury and U.S. Government agency obligations;
                    (3)  Obligations issued  by state  and municipal governments
                    and their agencies and instrumentalities;
                    (4) Bank obligations, including certificates of deposit  and
                        bankers acceptances;
                    (5) Commercial paper; and
                    (6)    Repurchase   agreements   collateralized   by   these
                        securities.
                    Investment grade corporate debt securities are those rated a
                    minimum  of  Baa3   by  Moody's   Investors  Service,   Inc.
                    ("Moody's")   or  BBB-  by  Standard  &  Poor's  Corporation
                    ("Standard & Poor's"). Investment grade commercial paper  is
                    rated  A-1  or better  by Standard  &  Poor's or  Prime-1 by
                    Moody's, or, if unrated, issued  by a corporation having  an
                    outstanding  unsecured  debt  issue  rated  A  or  better by
                    Moody's or Standard & Poor's. At least 70% of the Short-Term
                    Corporate  Portfolio's  assets  will  be  invested  in  debt
                    securities   rated  a  minimum  of   A3  by  Moody's  or  A-

                    Portfolio's  assets may be invested in debt securities rated
                    Baa by Moody's or BBB by Standard & Poor's. Securities rated
                    Baa or BBB are considered medium grade obligations. Interest
                    payments and  principal are  regarded  as adequate  for  the
                    present,  but  certain protective  elements found  in higher
                    rated bonds  may be  lacking.  Such bonds  lack  outstanding
                    investment  characteristics and,  in fact,  have speculative
                    characteristics as well.

                    In the  event  that a  security  held by  the  Portfolio  is
                    downgraded, the Portfolio may continue to hold such security
                    until  such  time as  the adviser  deems it  advantageous to
                    dispose of the security.

                    In an effort to minimize  fluctuations in market value,  the
                    Short-Term  Corporate Portfolio  is expected  to maintain an
                    dollar-weighted average maturity between 1 and 3 years.  The
                    Short-Term  Corporate Portfolio may  also hold securities of
                    foreign issuers provided such securities are denominated  in
                    U.S. dollars, and may invest in bond (interest rate) futures
                    and  options  to a  limited  extent. See  "Implementation of
                    Policies" for a description of these investment practices of
                    the Portfolio.

INTERMEDIATE-TERM   backed by the full faith and credit of the U.S.  Government.
BONDS               Also,  at  least  65%  of  the  Portfolio's  assets  will be
                    invested in  U.S.  Treasury  bills,  notes  and  bonds.  The
                    dollar-weighted   average  maturity  of   the  Portfolio  is
                    expected to range from 5 to 10 years.

                    The balance of  the Portfolio's  assets may  be invested  in
                    U.S.  Treasury or U.S. Government agency securities, as well
                    as  in   repurchase   agreements  collateralized   by   such
                    securities.  The Portfolio may also invest in bond (interest
                    rate)  futures  and  options   to  a  limited  extent.   See
                    "Implementation  of  Policies"  for a  description  of these
                    investment practices of the Portfolio.

                    The GNMA PORTFOLIO  invests at  least 80% of  its assets  in
                    Government  National Mortgage Association ("GNMA" or "Ginnie
                    Mae")  pass-through   certificates.  The   balance  of   the
                    Portfolio's assets may be invested in other U.S. Treasury or
                    U.S.  Government agency securities, as well as in repurchase
                    agreements collateralized by such securities. The  Portfolio
                    may  also invest in bond (interest rate) futures and options
                    to a limited extent. See "Implementation of Policies" for  a
                    description of these investment practices of the Portfolio.

                    GNMA    pass-through   certificates    are   mortgage-backed
                    securities representing part ownership of a pool of mortgage
                    loans.  Monthly  mortgage  payments  of  both  interest  and
                    principal  "pass  through"  from  homeowners  to certificate
                    investors, such as  the GNMA Portfolio.  The GNMA  Portfolio
                    reinvests the principal portion in additional securities and
                    distributes   the   interest  portion   as  income   to  the
                    Portfolio's shareholders. Under  normal circumstances,  GNMA
                    certificates are expected to provide higher yields than U.S.
                    Treasury securities of comparable maturity.

                    The  mortgage loans underlying  GNMA certificates--issued by
                    lenders such  as  mortgage bankers,  commercial  banks,  and
                    savings  and  loan  associations-are either  insured  by the
                    Federal Housing Administration  (FHA) or  guaranteed by  the
                    Veterans  Administration (VA).  Each pool  of mortgage loans
                    must also be approved by GNMA, a U.S. Government corporation
                    within  the   U.S.   Department   of   Housing   and   Urban

                    Development.  Once  GNMA  approval is  obtained,  the timely
                    payment  of  interest  and  principal  on  each   underlying
                    mortgage  loan is guaranteed by  the "full faith and credit"
                    of the U.S. Government.

                    Although stated  maturities on  GNMA certificates  generally
                    range  from 25 to 30 years, effective maturities are usually
                    much  shorter  due  to  the  prepayment  of  the  underlying
                    mortgages  by homeowners. On  average, GNMA certificates are
                    repaid  within   12  years   and   so  are   classified   as
                    intermediate-term securities.

                    THE  INTERMEDIATE-TERM  CORPORATE  PORTFOLIO  invests  in  a
                    diversified portfolio  of  investment  grade  corporate  and
                    Government  bonds. Under normal  circumstances, at least 65%
                    of the  Portfolio's assets  are  invested in  straight  debt
                    corporate  bonds rated a minimum of  Baa3 by Moody's or BBB-
                    by Standard & Poor's at the time of purchase.  Additionally,
                    at  least  80% of  the Portfolio's  assets will  normally be
                    invested in  a  combination of  investment  grade  corporate
                    bonds and securities of the U.S. Government and its agencies
                    and   instrumentalities.  The   Intermediate-Term  Corporate
                    Portfolio is expected to maintain a dollar-weighted  average
                    maturity between 5 and 10 years.

                    The  preponderance  of  the  Portfolio's  holdings  will  be
                    classified  in  the  top  three  credit-rating   categories.
                    Specifically, at least 70% of the Portfolio's assets will be
                    invested in the following securities:

                    (1)   Short-term   and   intermediate-term   corporate  debt
                    securities which at the time of purchase are rated a minimum
                        of A3 by Moody's or A- by Standard & Poor's;

                    (2) Securities  issued by  the  U.S. Government,  state  and
                    municipal governments or their agencies and
                        instrumentalities;

                    (3)  Commercial paper  of companies  having, at  the time of
                    purchase, outstanding debt securities rated as described  in
                        (1)  or commercial paper rated P-1  or P-2 by Moody's or
                        rated A-1 or A-2 by Standard & Poor's; and

                    (4)  Short-term  fixed  income   securities  held  as   cash
                    reserves,  including U.S. Treasury or U.S. Government agency
                        securities,   certificates    of    deposit,    bankers'
                        acceptances,  or repurchase agreements collateralized by
                        these securities.

                    Up to  30% of  the Intermediate-Term  Corporate  Portfolio's
                    assets may be invested in straight debt securities rated Baa
                    by  Moody's or BBB by  Standard & Poor's (see  page 13 for a
                    description of these ratings),  and in preferred stocks  and
                    convertible  securities. In  addition, not more  than 25% of
                    the Portfolio's assets may be invested in GNMA  certificates
                    or other mortgage-backed securities. Mortgage-backed securi-
                    ties  are  subject to  risks which  are  in addition  to and
                    distinct from the risks inherent in investments in corporate
                    bonds.  For  a  discussion  of  these  special  risks,   see
                    "Investment Risks." In the event that a security held by the
                    Portfolio  is downgraded, the Portfolio may continue to hold
                    such security until such time as the adviser deems it to  be
                    advantageous to dispose of the security.

                    The  Intermediate-Term  Corporate  Portfolio  may  also hold
                    securities of foreign issuers  provided such securities  are
                    denominated  in U.S. dollars. The  Portfolio may also invest
                    in bond (interest  rate) futures  and options  to a  limited
                    extent.  See "Implementation of  Policies" for a description

                    securities  of  the  U.S. Government  and  its  agencies and
                    instrumentalities. The average  dollar-weighted maturity  of
                    the Portfolio is expected to range from 15 to 25 years.

                    The investment policies for the Fund are not fundamental and

INVESTMENT RISKS    As mutual funds  investing in fixed  income securities,  the
THE PORTFOLIOS ARE  Portfolios  of the  Fund are  subject primarily  to interest
SUBJECT PRIMARILY   rate and credit  risk. INTEREST RATE  RISK is the  potential
TO INTEREST RATE,   for  a decline in bond prices  due to rising interest rates.
INCOME, CREDIT AND  In general, bond prices vary inversely with interest  rates.
MANAGER RISK        When  interest  rates  RISE,  bond  prices  generally  FALL.
                    Conversely, when interest rates FALL, bond prices  generally
                    RISE.  The  change  in  price  depends  on  several factors,
                    including the bond's maturity  date. In general, bonds  with
                    longer  maturities are more sensitive to changes in interest
                    rates than bonds with shorter maturities.

                    These principles of  interest rate risk  also apply to  U.S.
                    Treasury  and  U.S.  Government agency  securities.  As with
                    other bond investments, U.S. Government securities will rise
                    and fall  in  value as  interest  rates change.  A  SECURITY
                    BACKED  BY THE U.S. TREASURY OR THE FULL FAITH AND CREDIT OF
                    THE UNITED  STATES  IS  GUARANTEED ONLY  AS  TO  THE  TIMELY

                    CURRENT MARKET PRICES FOR SUCH SECURITIES ARE NOT GUARANTEED
                    AND WILL FLUCTUATE.

                    As  an illustration of interest  rate risk, the charts below
                    depict the effect of a  one and two percentage point  change

                    INCOME  RISK is the potential for a decline in a Portfolio's
                    income due  to falling  market interest  rates. In  relative
                    terms,   income  risk   will  be   higher  for   the  Fund's
                    shorter-term Portfolios and lower for the Fund's longer-term
                    Portfolios.

                    Each Portfolio of the Fund  is also subject to credit  risk.
                    CREDIT  RISK, also known as default risk, is the possibility
                    that a  bond issuer  will fail  to make  timely payments  of
                    interest  or principal to a Portfolio.  The credit risk of a
                    Portfolio  depends  on  the  quality  of  its   investments.
                    Reflecting  their higher  risks, lower-quality  bonds gener-
                    ally offer higher yields (all other factors being equal).

                    Besides interest rate  risk and credit  risk, investors  are
                    exposed  to PREPAYMENT RISK  in the GNMA  Portfolio and CALL
                    RISK in the Long-Term Corporate Portfolio.

                    Finally,  the   investment   advisers  manage   the   Fund's
                    Portfolios  according to the traditional methods of "active"
                    investment management, which involves the buying and selling
                    of securities  based  upon economic,  financial  and  market
                    analysis  and investment  judgement. MANAGER  RISK refers to
                    the possibility that  a Portfolio's  investment adviser  may
                    fail   to  execute   the  Portfolio's   investment  strategy
                    effectively. As a  result, a Portfolio  may fail to  achieve
                    its stated objective.

THREE SHORT-TERM    Interest   rate  risk   for  the   SHORT-TERM  U.S  TREASURY
PORTFOLIOS PROVIDE  PORTFOLIO,  the  SHORT-TERM   FEDERAL  PORTFOLIO,  and   the
MODERATE EXPOSURE   SHORT-TERM  CORPORATE PORTFOLIO should be modest. Because of
TO INTEREST RATE    their short-term  average  weighted  maturities,  the  three
RISK                short-term   Portfolios  are  expected  to  exhibit  LOW  TO
                    MODERATE price fluctuations as interest rates change.

                    The three Portfolios differ  principally in terms of  credit
                    quality   and  potential  yield.  For  the  Short-Term  U.S.
                    Treasury Portfolio,  credit risk  should be  negligible.  In
                    relative  terms, credit risk will be slightly higher for the
                    Short-Term Federal Portfolio because of its holdings of U.S.
                    Government agency securities.  (Even though  they carry  top
                    (Aaa)   credit   ratings,  "agency"   obligations   are  not
                    explicitly guaranteed  by the  U.S.  Government and  so  are
                    perceived  as  somewhat  riskier  than  comparable  Treasury
                    bonds.)

                    With its corporate bond  holdings, the Short-Term  Corporate
                    Portfolio  offers the highest exposure to credit risk of the
                    three  short-term  Portfolios.   However,  because  of   the
                    Portfolio's   well-diversified  holdings   and  emphasis  on
                    high-quality bonds,  overall  credit risk  should  still  be
                    quite low.

INTEREST RATE RISK  The  three  intermediate-term  Portfolios are  exposed  to a
FOR THE THREE       higher  degree  of  interest   rate  risk  than  the   three
INTERMEDIATE-TERM   short-term  Portfolios. The  INTERMEDIATE-TERM U.S. TREASURY
PORTFOLIOS WILL BE  PORTFOLIO, the  GNMA  PORTFOLIO  and  the  INTERMEDIATE-TERM
HIGHER              CORPORATE PORTFOLIO are expected to exhibit MODERATE TO HIGH
                    price  fluctuations as  interest rates  change. Credit risk,
                    however, should be  minimal for  the Intermediate-Term  U.S.
                    Treasury  and the GNMA Portfolios, as both Portfolios invest
                    primarily in "full faith and credit" securities of the  U.S.
                    Government.

                    Due  to its investments in corporate securities, credit risk
                    associated with  the Intermediate-Term  Corporate  Portfolio
                    will  be  higher than  for  the other  two intermediate-term
                    Portfolios.   However,   the   Intermediate-Term   Corporate
                    Portfolio's   diversification  and  quality  of  investments
                    should help limit credit risk.

                    The GNMA Portfolio is unique among the Fund's Portfolios  in
                    its  exposure  to prepayment  risk.  Prepayment risk  is the
                    possibility that,  as interest  rates fall,  homeowners  are
                    more  likely to  refinance their  home mortgages.  When home
                    mortgages are refinanced, the principal on GNMA certificates
                    held by the  Portfolio is "prepaid"  earlier than  expected.
                    The  GNMA  Portfolio  must then  reinvest  the unanticipated
                    principal in  new GNMA  certificates, just  at a  time  when
                    interest rates on new mortgage investments are falling.

                    Prepayment  risk  has  two  important  effects  on  the GNMA
                    Portfolio:

                    -  When  interest   rates  fall   and  additional   mortgage
                      prepayments  must be  reinvested at  lower interest rates,
                      the income of the GNMA Portfolio will be reduced.

                    - When interest rates fall,  prices on GNMA securities  will
                      not  rise as  much as  comparable Treasury  bonds, as bond
                      market  investors  anticipate  an  increase  in   mortgage
                      prepayments and a likely decline in income.

                    In part to compensate for this risk, the GNMA Portfolio will
                    generally  offer  higher  yields than  a  bond  portfolio of
                    comparable  quality--such  as  the  Intermediate-Term   U.S.
                    Treasury Portfolio.

FOR THE TWO         The  two  long-term  Portfolios are  exposed  to substantial
LONG-TERM           interest rate risk.  The LONG-TERM  U.S. TREASURY  PORTFOLIO
PORTFOLIOS,         and   the  LONG-TERM  CORPORATE  PORTFOLIO,  both  of  which
INTEREST RATE RISK  maintain average  maturities  in  excess of  15  years,  may
MAY BE SUBSTANTIAL  exhibit HIGH TO VERY HIGH price fluctuations due to changing
                    interest rates.

                    The  main difference  between the  two Portfolios  is credit
                    risk.  The   Long-Term  U.S.   Treasury  Portfolio   invests
                    primarily in "full faith and credit" U.S. Treasury bonds for
                    maximum  credit  protection, while  the  Long-Term Corporate
                    Portfolio invests in  investment grade  corporate bonds  for
                    higher  yields.  Although  credit  risk  for  the  Long-Term
                    Corporate Portfolio will be somewhat higher, overall  credit
                    risk   should  still  be  low  because  of  the  Portfolio's
                    well-diversified holdings and  its emphasis on  high-quality
                    bonds.

                    An  additional risk associated  with the Long-Term Corporate
                    Portfolio is call  risk. Call risk  is the possibility  that
                    corporate  bonds held by the  Portfolio will be repaid prior
                    to maturity. Call provisions, common in many corporate bonds
                    held by the  Portfolio, allow bond  issuers to redeem  bonds
                    prior  to  maturity (at  a  specified price).  When interest
                    rates are falling,  bond issuers often  exercise these  call
                    provisions, paying off bonds that carry high stated interest
                    rates  and often issuing  new bonds at  lower rates. For the
                    Portfolio, the result would be that bonds with high interest
                    rates are "called" and must be replaced with  lower-yielding
                    instruments.  In  these  circumstances,  the  income  of the
                    Portfolio would decline.

                    Reflecting these  additional  credit  and  call  risks,  the
                    Long-Term  Corporate Portfolio  will generally  offer higher
                    yields than the Long-Term U.S. Treasury Portfolio.

                    the  share price of  the Fund's Portfolios,  the Fund may be
                    inappropriate for short-term  investors who require  maximum
                    stability of principal. Because of the risks associated with
                    bond  investments, the  Fund is  intended to  be a long-term
                    investment vehicle and is not designed to provide  investors
                    with  a  means  of  speculating  on  short-term  bond market
                    movements.

                    Investors who engage in excessive account activity  generate
                    additional  costs  which  are  borne by  all  of  the Fund's
                    shareholders. In order to minimize  such costs the Fund  has
                    adopted  the following policies. The Fund reserves the right
                    to reject any purchase request (including exchange purchases
                    from other Vanguard portfolios) that is reasonably deemed to
                    be disruptive  to  efficient  portfolio  management,  either
                    because   of  the  timing  of  the  investment  or  previous
                    excessive trading by  the investor.  Additionally, the  Fund
                    has  adopted exchange privilege  limitations as described in
                    the section "Exchange  Privilege Limitations." Finally,  the
                    Fund  reserves  the right  to  suspend the  offering  of its
                    shares.

                    You  should  base   your  selection  of   a  Portfolio   (or
                    Portfolios)  of  the  Fund  on  your  own  objectives,  risk
                    preferences, and time horizon.

                    Three short-term  Portfolios--the SHORT-TERM  U.S.  TREASURY
                    PORTFOLIO,  SHORT-TERM  FEDERAL  PORTFOLIO,  and  SHORT-TERM
                    CORPORATE PORTFOLIO--are  designed  for  investors  who  are
                    seeking yields that are more durable and usually higher than
                    those  available  from  money  market  funds,  and  who  can
                    tolerate  modest  fluctuations   in  the   value  of   their
                    investment.  The  choice among  the three  is one  of credit
                    quality--U.S.   Treasury,   U.S.   Government   agency,   or
                    corporate.

                    The three intermediate-term Portfolios--the
                    INTERMEDIATE-TERM   U.S.   TREASURY   PORTFOLIO,   the  GNMA
                    PORTFOLIO and  the INTERMEDIATE-TERM  CORPORATE  PORTFOLIO--
                    offer  high  credit quality,  higher  yields and  a steadier
                    income than available from the three short-term  Portfolios.
                    Price  swings,  however,  can  be  substantial.  The  choice
                    between the  three  is  again one  of  credit  quality--U.S.
                    Treasury,  U.S. Government Agency,  or corporate--as well as
                    one of prepayment  risk (i.e.,  whether you  are willing  to
                    take  on  the  prepayment  risk  of  the  GNMA  Portfolio in
                    exchange for generally higher yields).

                    The two long-term  Portfolios, the  LONG-TERM U.S.  TREASURY
                    PORTFOLIO   and  the  LONG-TERM   CORPORATE  PORTFOLIO,  are
                    designed for  investors  seeking  high  credit  quality  and
                    steady  levels of income, and  who can withstand potentially
                    large fluctuations in the market value of their  investment.
                    The choice between the two is one of credit quality and call
                    risk.  The  Long-Term Corporate  Portfolio  generally offers
                    higher yields than the Long-Term U.S. Treasury Portfolio  in
                    exchange for higher credit and call risks.

IMPLEMENTATION OF   Each  Portfolio of the Fund utilizes a variety of investment
POLICIES            practices in pursuit of its objective.

EACH PORTFOLIO MAY  Each  Portfolio  of  the  Fund  may  invest  in   repurchase
INVEST IN           agreements according to the restrictions and limitations set
REPURCHASE          forth  in "Investment Policies." A repurchase agreement is a
AGREEMENTS          means  of  investing  monies  for  a  short  period.  In   a
                    repurchase  agreement, a  seller--a U.S.  commercial bank or
                    recognized   U.S.   securities   dealer--sells    securities
</TABLE>

                                                                              19

                    to  a Portfolio and  agrees to repurchase  the securities at
                    the Portfolio's cost plus interest within a specified period
                    (normally one day).  In these  transactions, the  securities
                    purchased  by the Portfolio will have a total value equal to
                    or in excess of the  value of the repurchase agreement,  and
                    will be held by the Fund's Custodian Bank until repurchased.

                    The use of repurchase agreements involves certain risks. For
                    example, if the other party to the agreement defaults on its
                    obligation  to repurchase the underlying  security at a time
                    when the value of the  security has declined, the  Portfolio
                    may  incur a loss  upon disposition of  the security. If the
                    other party to the  agreement becomes insolvent and  subject
                    to  liquidation or reorganization  under the Bankruptcy Code
                    or other laws,  a court  may determine  that the  underlying
                    security  is collateral for a loan  by the Portfolio and not
                    within the  control  of  the Portfolio.  As  a  result,  the
                    Portfolio's  ability to  realize on  such collateral  may be
                    automatically stayed.  Finally,  it  is  possible  that  the
                    Portfolio  may not be  able to substantiate  its interest in
                    the underlying  security  and  may be  deemed  an  unsecured
                    creditor  of the  other party  to the  agreement. While each
                    Portfolio's  management  acknowledges  these  risks,  it  is
                    expected   that  they  can  be  controlled  through  careful
                    monitoring procedures.

EACH PORTFOLIO MAY  Each Portfolio of the Fund may own restricted securities  to
OWN RESTRICTED      a limited extent. Restricted securities are securities which
SECURITIES          are   not  freely   marketable  or  which   are  subject  to
                    restrictions upon  sale under  the Securities  Act of  1933.
                    Each  Portfolio may  invest up to  15% of its  net assets in
                    restricted  securities.  (Included  within  this  limit  are
                    restricted  securities and, other securities for which price
                    quotations are not readily available.)

THREE PORTFOLIOS    The Short-Term  Corporate, Intermediate-Term  Corporate  and
MAY INVEST IN       Long-Term   Corporate  Portfolios  may  hold  securities  of
SECURITIES OF       foreign issuers, but all such securities must be denominated
FOREIGN ISSUERS     in U.S. dollars. Securities of foreign issuers may trade  in
                    U.S.  or foreign  securities markets.  Securities of foreign
                    issuers may involve investment risks that are different from
                    those of domestic issuers. Such risks include the effect  of
                    foreign  economic policies and  conditions, future political
                    and economic developments,  and the  possible imposition  of
                    exchange controls or other foreign governmental restrictions
                    on  foreign debt  issuers. There  may also  be less publicly
                    available information about a foreign issuer than a domestic
                    issuer of  securities.  Foreign issuers  are  generally  not
                    subject  to the  uniform accounting,  auditing and financial
                    reporting standards that  apply to  domestic issuers.  Also,
                    foreign   debt  markets   may  be   characterized  by  lower
                    liquidity, greater price volatility, and higher transactions
                    costs. Additionally,  it  may  be  difficult  to  obtain  or
                    enforce a legal judgement in a foreign court.

MOST PORTFOLIOS     Each  Portfolio  of  the  Fund,  except  for  the Short-Term
MAY INVEST IN       Federal Portfolio,  may  invest  in  futures  contracts  and
FUTURES CONTRACTS,  options  to a limited extent.  Specifically, a Portfolio may
OPTIONS, AND OTHER  enter into futures contracts provided that not more than  5%
DERIVATIVE          of  its  assets are  required as  a futures  contract margin
SECURITIES          deposit; in  addition, a  Portfolio may  enter into  futures
                    contracts  and options transactions only  to the extent that
                    obligations under such  contracts or transactions  represent
                    not more than 20% of the Portfolio's assets.

                    Futures  contracts  and  options  may  be  used  for several
                    reasons: 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  Portfolios intend to use
                    futures contracts only  for bona fide  hedging purposes  and
                    will  not use  futures contracts or  options for speculative
                    purposes.

FUTURES CONTRACTS   The  primary  risks  associated  with  the  use  of  futures
AND OPTIONS POSE    contracts and options are: (i) imperfect correlation between
CERTAIN RISKS       the  change in market value of the bonds held by a Portfolio
                    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  only in  those
                    contracts  whose price fluctuations are expected to resemble
                    those of  the Portfolio's  underlying securities.  The  risk
                    that  a  Portfolio will  be unable  to  close out  a futures
                    position will be  minimized by entering  into such  transac-
                    tions  on  a national  exchange  with an  active  and liquid
                    secondary market.

                    The risk  of  loss  in trading  futures  contracts  in  some
                    strategies  can be substantial,  due both to  the low margin
                    deposits required and the extremely high degree of  leverage
                    involved in futures pricing. As a result, a relatively small
                    price movement in a futures contract may result in immediate
                    and  substantial  loss  (or  gain)  to  the  investor.  When
                    investing in futures contracts,  a Portfolio will  segregate
                    cash  or cash  equivalents in  the amount  of the underlying
                    obligation.

                    Derivatives are  instruments whose  value  is linked  to  or
                    derived  from an  underlying security.  The most  common are
                    futures  and  options  which  are  described  above.   Other
                    derivatives  include swaps, inverse floaters, IO's (interest
                    only), and PO's (principal only). Derivatives may be  traded
                    separately  on exchanges or  in the over-the-counter market,
                    or they may be imbedded in other securities. The most common
                    imbedded derivative  is  the  call  option  attached  to  or
                    imbedded  in  a  callable government  or  callable corporate
                    bond. The  owner  of a  traditional  callable bond  holds  a
                    combination  of a long position in a non-callable bond and a
                    short position in a call option on that bond, i.e. the  bond
                    issuer  has the right to call  the bond away from the holder
                    of the  bond. Any  of  these instruments  may also  be  used
                    individually  or in combination to hedge against unfavorable
                    changes in interest  rates, or to  speculate on  anticipated
                    changes  in  interest rates.  Derivatives may  be structured
                    with no or a high  degree of leverage. When derivatives  are
                    used  as hedges,  the risk  incurred is  that the derivative
                    instrument's value may change differently than the value  of
                    the  security being  hedged. This "basis  risk" is generally
                    lower than the risk associated with an unhedged position  in
                    the  security  being  hedged.  Some  derivatives  may entail
                    liquidity risk, i.e. the risk that the instrument cannot  be
                    sold  at  a  reasonable price  in  highly  volatile markets.
                    Leveraged  derivatives   used  for   speculation  are   very
                    volatile,  and  therefore, very  risky. However,  the Fund's
                    Portfolios will  only  utilize derivatives  for  hedging  or
                    arbitrage   purposes,  and  not  for  speculative  purposes.
                    Over-the-counter derivatives  involve a  counterparty  risk,
                    i.e.  the  risk that  the individual  or institution  on the
                    other side of the  agreement will not  or cannot meet  their
                    obligations under the derivative agreement.

EACH PORTFOLIO MAY  Each   Portfolio  of  the  Fund   may  lend  its  investment
LEND ITS            securities to qualified  institutional investors for  either
SECURITIES          short-term  or  long-term purposes  of  realizing additional
                    income.  Loans  of  securities   by  a  Portfolio  will   be
                    collateralized  by  cash, letters  of credit,  or securities
                    issued or guaranteed by the U.S. Government or its agencies.
                    The collateral  will  equal at  least  100% of  the  current
                    market  value of the  loaned securities, and  such loans may
                    not  exceed  33  1/3%  of  the  value  of  the   Portfolio's
                    securities.

MOST PORTFOLIOS     The    Short-Term   Federal,   Short-and   Intermediate-Term
MAY INVEST IN CMOS  Corporate and  the Short-,  Intermediate-and Long-Term  U.S.
                    Treasury  Portfolios may  invest in  collateralized mortgage
                    obligations (CMOs), bonds that  are collateralized by  whole
                    loan  mortgages or mortgage  pass-through securities. In the
                    case of the Short-Term Federal and the Short-, Intermediate-
                    and Long-Term U.S. Treasury Portfolios, only CMOs issued  by
                    agencies or instrumentalities of the U.S. Government will be
                    purchased.    However,   the   Short-and   Intermediate-Term
                    Corporate Portfolios may also purchase privately-issued CMOs
                    carrying investment grade ratings. The bonds issued under  a
                    CMO   structure  are   divided  into   groups  with  varying
                    maturities, and the cash flows generated by the mortgages or
                    mortgage pass-through securities in the collateral pool  are
                    used to first pay interest and then pay principal to the CMO
                    bondholders.  Under  the  CMO  structure,  the  repayment of
                    principal among  the  different  groups  is  prioritized  in
                    accordance  with the  terms of the  particular CMO issuance.
                    The "fastest-pay"  group  of  bonds,  as  specified  in  the
                    prospectus  for  the issuance,  would initially  receive all
                    principal payments. When that group of bonds is retired, the
                    next group or groups, in  the sequence, as specified in  the
                    prospectus,  receive all of the principal payments until all
                    of the  groups  are retired.  Aside  from market  risk,  the
                    primary  risk involved in  any mortgage security,  such as a
                    CMO issuance, is  its exposure  to prepayment  risk. To  the
                    extent  a particular group of bonds is exposed to this risk,
                    the bondholder  is  generally  compensated in  the  form  of
                    higher  yield (see "Investment Risks").  In order to provide
                    security, in addition to the underlying collateral, many CMO
                    issues also include  minimum reinvestment  rate and  minimum
                    sinking-fund  guarantees.  Typically,  the  Portfolios  will
                    invest in those CMOs  that most appropriately reflect  their
                    average  maturities and market  risk profiles. Consequently,
                    the Short-Term Portfolios  invest only in  CMOs with  highly
                    predictable  short-term  average maturities.  Similarly, the
                    Intermediate-Term Portfolios will invest in those CMOs  that
                    carry  market risks and  expected average maturities consis-
                    tent with intermediate-term  bonds, and  the Long-Term  U.S.
                    Treasury  Portfolio will  invest in  those CMO's  that carry
                    market risks and expected average maturities consistent with
                    long-term bonds.

                    The maturity of some classes  of CMOs may be very  difficult
                    to predict because any such predictions are highly dependent
                    upon  assumptions regarding  the prepayments  which CMOs may
                    experience. Deviations  in  the actual  prepayments  experi-
                    enced  may  significantly  affect the  ultimate  maturity of
                    CMOs,  and  in  such  an   event,  the  maturity  and   risk
                    characteristics  of CMOs purchased by  the Portfolios may be
                    significantly greater or less than intended. The possibility
                    that rising interest rates may cause prepayments to occur at
                    a slower than expected rate is known as extension risk. This
                    particular risk  may  effectively  change a  CMO  which  was
                    considered   short-or  intermediate-term  at   the  time  of
                    purchase into a long-term security. Alternatively, there are
                    certain classes of  CMOs that are  by design constructed  to
                    have  highly predictable average  maturities. Such CMOs will
                    retain their relative predictability  over a broad range  of
                    prepayment  experience.  The  Portfolios  expect  to control
                    extension risk by purchasing these specific classes of  CMOs
                    which,   in   the   advisers'   opinions,   are   reasonably
                    predictable.

PORTFOLIO TURNOVER  Although they generally  seek to invest  for the long  term,
RATES WILL VARY     the  Portfolios  of  the  Fund  retain  the  right  to  sell
                    securities regardless of how long they have been held. It is
                    anticipated that the annual portfolio turnover rate for  the
                    GNMA and Long-Term

<S>                 <C>
                    Corporate  Portfolios will not exceed  100%. A 100% turnover
                    rate would occur, for example, if all of the securities in a
                    Portfolio  were   replaced   within  one   year.   For   the
                    Intermediate-Term   and  Long-Term  U.S.  Treasury  and  the
                    Intermediate-Term Corporate  Portfolios, portfolio  turnover
                    rates  will generally  not exceed  200%. For  the Short-Term
                    U.S. Treasury, Short-Term Federal, and Short-Term  Corporate
                    Portfolios,  portfolio turnover rates will  be higher due to
                    the short-term maturities of  the securities purchased,  but
                    are  not expected to exceed  300%. A higher Portfolio turno-
                    ver  rate  will  cause  a  Portfolio  to  incur   additional
                    brokerage  costs  and may  cause  a Portfolio  to  realize a
                    higher level of capital gains or losses.

                    situations. Some of these  limitations are that a  Portfolio
                    will not:
THE FUND HAS
ADOPTED
CERTAIN             (a)  with respect to 75% of  its assets, invest more than 5%
FUNDAMENTAL         of the value of its assets  in the securities of any  single
LIMITATIONS             company;
                    (b)  with respect to  75% of its  assets, purchase more than
                    10% of the voting securities of any issuer;

                    (c) invest more than 5% of  its assets in the securities  of
                    companies  that have a continuous  operating history of less
                        than three years;

                    (d) invest more than 25% of its assets in any one  industry,
                    provided  that:  (i)  this  limitation  does  not  apply  to
                        obligations issued or guaranteed by the U.S.  Government
                        or  its  agencies  or  instrumentalities;  (ii)  utility
                        companies will be divided  according to their  services.
                        For  example, gas, gas  transmission, electric, electric
                        and  gas,  and  telephone  will  each  be  considered  a
                        separate industry; and (iii) financial service companies
                        will  be classified according to  the end users of their
                        services. For example, automobile finance, bank finance,
                        and diversified finance will  be considered as  separate
                        industries;

                    (e)  borrow money, except that the Portfolio 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  Portfolio'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
                        Portfolio's net assets, the Portfolio will not make  any
                        additional investments.

MANAGEMENT OF THE   The Fund is  a member  of The Vanguard  Group of  Investment
FUND                Companies,  a  family  of 32  investment  companies  with 78
VANGUARD            distinct portfolios  and  total  assets in  excess  of  $120
ADMINISTERS AND     billion.   Through  their  jointly   owned  subsidiary,  The
DISTRIBUTES THE     Vanguard Group, Inc.  ("Vanguard"), the Fund  and the  other
FUND                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 struc-
                    ture, the Vanguard funds have costs substantially lower than
                    those of most competing mutual  funds. In 1993, the  average
                    expense  ratio (annual costs including advisory fees divided
                    by total  net assets)  for the  Vanguard funds  amounted  to
                    approximately  .30% compared to an  average of 1.02% for the
                    mutual fund  industry (data  provided by  Lipper  Analytical
                    Services).

                    The  Officers of the Fund  oversee its day-to-day operations
                    and are responsible  to the Fund's  Board of Directors.  The
                    Directors  set broad  policies for  the Fund  and choose its
                    Officers. A list of the  Directors and Officers of the  Fund
                    and  a statement  of their  present positions  and principal
                    occupations during the past five  years can be found in  the
                    Statement of Additional Information.

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

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

                    since 1960.

                    As of March 31, 1994, Paul D. Kaplan, Senior Vice  President
                    of WMC, assumed the duties of portfolio manager for the GNMA
                    portfolio.  Prior to  this change, Mr.  Kaplan was assistant
                    portfolio manager  for the  GNMA Portfolio.  Mr. Kaplan  has
                    been  associated with  WMC for  16 years  and also currently
                    manages the  bond  component of  Vanguard  Utilities  Income
                    Portfolio.

                    Also  as  of March  31, 1994,  Earl  E. McEvoy,  Senior Vice
                    President of WMC, assumed responsibility for the  management
                    of  the  Fund's  Long-Term Corporate  Portfolio.  Mr. McEvoy
                    currently manages the Fund's High Yield Corporate  Portfolio
                    as  well  as  Vanguard  Preferred Stock  Fund  and  the bond
                    component of Vanguard/Wellesley Income Fund, Inc. Mr. McEvoy
                    has also been associated with Wellington Management  Company
                    for 16 years.

                    Mr.  Kaplan  and Mr.  McEvoy are  supported by  research and
                    other investment services provided by the professional staff
                    of WMC.

                    Under the Fund's investment advisory agreement, the fee paid
                    to WMC is based on the  total assets of the GNMA  Portfolio,
                    the  Long-Term Corporate Portfolio, and  the total assets of
                    the High Yield Corporate Portfolio of Vanguard Fixed  Income
                    Securities  Fund which  is not included  in this Prospectus.
                    The three Portfolios pay WMC an aggregate fee at the end  of
                    each fiscal quarter, calculated by applying a quarterly rate
                    based  on  the  following annual  percentage  rates,  to the
                    aggregate  average  month-end  net   assets  of  the   three
                    Portfolios:

                    The advisory fee is then apportioned to each Portfolio based
                    on  the relative net assets of each; provided, however, that
                    following such an allocation, the fee to be paid by the GNMA
                    Portfolio is  reduced  by  75%,  and the  fee  paid  by  the
                    Long-Term  Corporate Portfolio  is reduced  by 50%.  For the
                    fiscal year ended January 31,  1994, the GNMA and  Long-Term
                    Corporate  Portfolios paid annual advisory fees to WMC equal
                    to, respectively, .02 of  1%, and .04 of  1% of average  net
                    assets. These fees were paid pursuant to a previous advisory
                    agreement that called for a higher rate of fees.

                    The  investment advisory agreement  authorizes WMC to select
                    brokers or dealers  to execute purchases  and sales of  each
                    Portfolio's  securities,  and directs  WMC  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 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,  WMC may place orders  with
                    qualified  broker-dealers who recommend  the Fund to clients
                    if the Officers of the Fund believe that the quality of  the
                    transaction  and the commission are  comparable to what they
                    would be with other qualified brokerage firms.

VANGUARD FIXED      The Short-Term U.S. Treasury, Short-Term Federal, Short  and
INCOME GROUP        Intermediate-Term  Corporate, and Intermediate-and Long-Term
                    U.S. Treasury  Portfolios  receive all  investment  advisory
                    services  on an  at-cost basis from  Vanguard's Fixed Income
                    Group. The Group also provides investment advisory  services
                    to  several other Vanguard money market and bond portfolios,
                    both taxable and tax-exempt.  Total assets under  management
                    by  Vanguard's  Fixed Income  Group were  $52 billion  as of
                    December 31, 1993.

                    Ian A.  MacKinnon, Senior  Vice President  of Vanguard,  has
                    been in charge of the Fixed Income Group since its inception
                    in  1981. Mr. MacKinnon is responsible for setting the broad
                    investment  strategies  employed  by   the  Fund,  and   for
                    overseeing   the  portfolio  managers  who  implement  those
                    strategies on  a  day-to-day  basis.  The  Fund's  portfolio
                    managers are as follows:

                    - Robert F. Auwaerter, Vice President of Vanguard, serves as
                      portfolio  manager  of the  Short-Term  Federal, Long-Term
                      U.S. Treasury Portfolio, Short-Term Corporate,
                      Intermediate-Term  U.S.  Treasury,  and  Intermediate-Term
                      Corporate  Portfolios.  Associated with  the  Fixed Income
                      Group since 1981, Mr. Auwaerter has managed the Short-Term
                      Corporate  Portfolio  since   1983,  the  Long-Term   U.S.
                      Treasury  Portfolio  since 1994  and  each of  these other
                      Portfolios since their respective inceptions. (Previously,
                      the Long-Term  U.S.  Treasury  Portfolio  was  managed  by
                      Anthony Jiorle.)

                    - John Hollyer, Assistant Vice President of Vanguard, serves
                      as  portfolio  manager  of  the  Short-Term  U.S. Treasury
                      Portfolio. Associated with  the Fixed  Income Group  since
                      1989,  Mr. Hollyer  began managing the  Portfolio in 1993.
                      (Previously, the Portfolio was managed by Mr.  Auwaerter.)
                      For  two  years  prior to  joining  Vanguard,  Mr. Hollyer
                      traded  U.S.   Government  bonds   for  an   international
                      investment bank.

                    The   Fixed   Income  Group   manages  the   investment  and
                    reinvestment of  the  assets  of these  six  Portfolios  and
                    continuously   reviews,  supervises   and  administers  each
                    Portfolio's investment program, subject to the maturity  and
                    quality   standards   specified  in   this   Prospectus  and
                    supplemental guidelines  approved  by the  Fund's  Board  of
                    Directors. The Fixed Income Group's selection of investments
                    for  the  Portfolios  is  based  on:  (a)  continuing credit
                    analysis of  those instruments  held in  the Portfolios  and
                    those  being considered for  inclusion therein; (b) possible
                    disparities in yield  relationships between different  money
                    market  instruments; and (c) actual or anticipated movements
                    in the general level of interest rates.

                    Vanguard's Fixed Income  Group is also  responsible for  the
                    placement  of portfolio transactions  and the negotiation of
                    commissions for the six Portfolios. The purchase and sale of
                    investment   securities   will   ordinarily   be   principal
                    transactions.   Portfolio   securities   will   normally  be
                    purchased directly from the issuer or from an underwriter or
                    market maker for  the securities. There  usually will be  no
                    brokerage  commissions  paid by  a Portfolio  for securities
                    purchased from  an issuer.  Purchases from  underwriters  of
                    securities  will include a commission  or concession paid by
                    the issuer to  the underwriter, and  purchases from  dealers
                    serving as market makers will include a dealer's mark-up.

                    In  purchasing and  selling securities  for each  of the six
                    Portfolios, it  is  the  Fund's policy  to  seek  to  obtain
                    quality  execution  at  the most  favorable  prices, through
                    responsible broker-dealers. In  selecting broker-dealers  to
                    execute  the  securities  transactions  for  the Portfolios,
                    consideration will be given to such factors as the price  of
                    the  security;  the rate  of  the commission;  the  size and
                    difficulty  of  the   order;  the  reliability,   integrity,
                    financial  condition, general execution  and operational ca-
                    pabilities of the competing broker-dealer; and the brokerage
                    and research services provided to the Fund.

                    Vanguard's  Fixed   Income  Group   may  occasionally   make
                    recommendations  to  other Vanguard  Funds or  clients which
                    result   in   their   purchasing   or   selling   securities
                    simultaneously  with a Portfolio  of the Fund.  As a result,
                    the demand for securities being  purchased or the supply  of
                    securities  being sold may increase,  and this could have an
                    adverse effect on the price  of those securities. It is  the
                    policy  of the  Fixed Income Group  not to  favor one client
                    over another in making recommendations or placing an  order.
                    If  two or more  clients are purchasing  a given security on
                    the same day from the same broker-dealer, such  transactions
                    may be averaged as to price.

                    Although the Fund does not market its shares through brokers
                    or  dealers, the  Fixed Income  Group may  place orders with
                    qualified broker-dealers who recommend  the Fund to  clients
                    if  the  Fund's Officers  believe  that the  quality  of the
                    transaction and the commission  are comparable to what  they
                    would be with other qualified brokerage firms.

THE FIRST BUSINESS  day of each month. Net capital gains distributions, if  any,
DAY                 will be made annually.
OF EACH MONTH       The  Fund's dividend and capital  gains distributions may be
                    reinvested in  additional shares  or received  in cash.  See
                    "Choosing  a Distribution Option" for a description of these
                    distribution methods.

                    In order to satisfy certain  requirements of the Tax  Reform
                    Act  of  1986, the  Fund may  declare year-end  dividend and
                    capital   gains   distributions   during   December.    Such
                    distributions,  if received  by shareholders  by January 31,
                    are deemed to  have been paid  by the Fund  and received  by
                    shareholders on December 31 of the prior year.

                    Each  Portfolio of the  Fund intends to  continue to qualify
                    for taxation as a  "regulated investment company" under  the
                    Internal Revenue Code so that none of the Portfolios will 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.  For corporate  investors,
                    dividends  paid by the Fund  from net investment income will
                    generally not qualify  for the intercorporate  dividends-re-
                    ceived deduction.

                    Distributions paid by the Fund from long-term capital gains,
                    whether received in cash or reinvested in additional shares,
                    are  taxable as  long-term capital gains,  regardless of the
                    length of time you  have owned shares  in the Fund.  Capital

                    distributions  are made  when the Fund  realizes net capital
                    gains on sales of portfolio securities during the year.  For
                    the  Fund, realized capital  gains are not  expected to be a
                    significant or predictable part of investment return.

                    The Fund will notify  you annually as to  the tax status  of
                    dividend  and capital gains distributions  paid by the Fund.
                    The Fund is managed without regard to tax ramifications.

A CAPITAL GAIN OR   A sale of  shares of  the Fund is  a taxable  event and  may
LOSS MAY BE         result in a capital gain or loss. A capital gain or loss may
REALIZED UPON       be  realized  from  an  ordinary  redemption  of  shares,  a
EXCHANGE OR         check-writing redemption, or an  exchange of shares  between
REDEMPTION          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. However, depending on
                    provisions of  your  state's  tax  law,  the  portion  of  a
                    Portfolio's income derived from "full faith and credit" U.S.
                    Treasury  obligations  may be  exempt  from state  and local
                    taxes. The Fund  will indicate  each year the  portion of  a
                    Portfolio's  income,  if  any,  that  may  qualify  for this
                    exemption.

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

                    The  Fund  has obtained  a  Certificate of  Authority  to do
                    business as a foreign  corporation in Pennsylvania and  does
                    business  and  maintains an  office  in that  state.  In the
                    opinion of counsel, the shares  of the Fund are exempt  from
                    Pennsylvania personal property taxes.

                    The  tax discussion set forth  above is included for general
                    information only. Prospective investors should consult their
                    own tax  advisers  concerning  the tax  consequences  of  an
                    investment in the Fund.

THE SHARE PRICE OF  The  share  price or  "net asset  value"  per share  of each
EACH PORTFOLIO      Portfolio is computed daily by  dividing the total value  of
                    the investments and other assets of each Portfolio, less any
                    liabilities,   by  the  total  outstanding  shares  of  such
                    Portfolio. The net asset value  per share of each  Portfolio
                    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. 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  this  ordinarily  will  be  the over-the-counter
                    market.

                    However, bonds  and other  fixed  income securities  may  be
                    valued  on the basis of prices provided by a pricing service
                    when such prices  are believed  to reflect  the fair  market
                    value  of such securities. The  prices provided by a pricing
                    service may be determined without regard to bid or last sale
                    prices but take into  account institutional size trading  in
                    similar groups of securities and any developments related to
                    specific  securities. Securities  not priced  in this manner
                    are valued at the most recent

                    used,  at  the  latest  quoted sale  price  on  the  date of
                    valuation. Short-term instruments are valued at cost,  which
                    approximates  market value. Other  assets and securities for
                    which no quotations are readily available will be valued  in
                    good  faith at fair market value using methods determined by
                    the Board of Directors.

                    Each Portfolio's  share  price can  be  found daily  in  the
                    mutual  fund  listings of  most  major newspapers  under the
                    heading of The Vanguard Group.
- --------------------------------------------------------------------------------
GENERAL             The  Fund  is  a  Maryland  corporation.  The  Articles   of
INFORMATION         Incorporation  permit the  Directors to  issue 3,500,000,000
                    shares of common stock, with a $.001 par value. The Board of
                    Directors has the  power to  designate one  or more  classes
                    ("Portfolios")  of shares of common stock and to classify or
                    reclassify any unissued shares with respect to such classes.
                    Currently the Fund is offering shares of nine Portfolios.

                    The  shares   of  each   Portfolio   are  fully   paid   and
                    non-assessable;   have  no  preference   as  to  conversion,
                    exchange, dividends, retirement or other features; and  have
                    no  pre-emptive  rights.  Such  shares  have  non-cumulative
                    voting rights, meaning that the holders of more than 50%  of
                    the  shares voting for  the election of  Directors can elect
                    100% of the Directors if they so choose.

                    Annual meetings of shareholders will  not be held except  as
                    required  by the  Investment Company  Act of  1940 and other
                    applicable law. An annual  meeting will be  held to vote  on
                    the  removal  of  a Director  or  Directors of  the  Fund if
                    requested in writing by the holders of not less than 10%  of
                    the outstanding shares of the Fund.

                    All securities and cash for the GNMA and Long-Term Corporate
                    Portfolios  are held  by Morgan Guaranty  Trust Company, New
                    York, NY. For the Short-Term Federal, Short-Term  Corporate,
                    and  Long-Term U.S. Treasury  Portfolios, all securities and
                    cash are held  by CoreStates Bank,  N.A., Philadelphia,  PA.
                    For  the Short-Term and  Intermediate-Term U.S. Treasury and
                    the Intermediate Term  Corporate Portfolios, all  securities
                    and  cash are held  by State Street  Bank and Trust Company,
                    Boston, MA.  The Vanguard  Group,  Inc., Valley  Forge,  PA,
                    serves as the Fund's Transfer and Dividend Disbursing Agent.
                    Price  Waterhouse serves as  independent accountants for the
                    Fund and will audit  its financial statements annually.  The
                    Fund is not involved in any litigation.

                    indicating the Portfolio you have chosen and the amount  you
                    wish  to invest. Your  purchase must be  equal to or greater
                    than the $3,000 minimum initial investment requirement for a
                    Portfolio  ($500  for  Individual  Retirement  Accounts  and
                    Uniform  Gifts/Transfers to  Minors Act  accounts). You must
                    open a new Individual Retirement  Account by mail (IRAs  may
                    not  be  opened  by  wire)  using  a  Vanguard  IRA Adoption
                    Agreement. Your purchase  must be equal  to or greater  than
                    the $500 minimum initial investment requirement, but no more
                    than  $2,000 if you  are making a  regular IRA Contribution.
                    Rollover contributions are generally  limited to the  amount
                    withdrawn  within  the past  60 days  from  an IRA  or other
                    qualified retirement plan. If  you need assistance with  the
                    forms  or  have  any  questions,  please  call  our Investor

                    types   of   account   registrations   (e.g.,  corporations,
                    associations,  other  organizations,  trusts  or  powers  of

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

                    The Fund's shares are  purchased at the next-determined  net
                    asset  value after your investment  has been received in the
                    form of  Federal  Funds.  See "When  Your  Account  Will  Be
                    Credited."  The Fund  is offered  on a  no-load basis (i.e.,
                    there are no sales commissions or 12b-1 fees).

ADDITIONAL          Subsequent investments to  regular accounts may  be made  by
INVESTMENTS         mail  ($100 minimum per Portfolio), wire ($1,000 minimum per
                    Portfolio), 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

TAX CAUTION         Under  Federal  tax  laws,  each  Portfolio  is  required to
INVESTORS SHOULD    distribute  net  capital  gains   and  dividend  income   to
ASK                 Portfolio  shareholders. These distributions are made to all
ABOUT THE TIMING    shareholders  who   own   Portfolio   shares   as   of   the
OF                  distribution's  record  date,  regardless  of  how  long the
CAPITAL GAINS AND   shares have been owned. Purchasing shares just prior to  the
DIVIDEND            record  date  could  have  significant  impact  on  your tax
DISTRIBUTIONS       liability for the year. For example, if you purchase  shares
BEFORE INVESTING    immediately  prior to the  record date of  a sizable capital
                    gain, you  will  be assessed  taxes  on the  amount  of  the
                    capital   gain  distribution  even   though  you  owned  the
                    Portfolio shares for just a short period of time. (Taxes are
                    due on the  distributions even  if the dividend  or gain  is
                    reinvested  in additional Portfolio shares.) While the total
                    value of your investment will be the same after the  capital
                    gain   distribution--the   amount   of   the   capital  gain
                    distribution will offset the drop in the net asset value  of
                    the  shares--you should be aware of the tax implications the
                    timing of your purchase may have.

                    Prospective  investors  should,  therefore,  inquire   about
                    potential  distributions before investing. Each Portfolio of
                    the Fund's annual capital gains distribution normally occurs
                    in December, while  income dividends are  generally paid  on
                    the  first  business  day  of  each  month.  For  additional
                    information on  distributions  and taxes,  see  the  section
                    titled "Dividends, Capital Gains, and Taxes."

                    FURTHER ASSISTANCE.

SIGNATURE           For  our  mutual  protection,  we  may  require  a signature
GUARANTEES          guarantee  on  certain   written  transaction  requests.   A
                    signature guarantee verifies the authenticity of your signa-
                    ture  and may be obtained from  banks, brokers and any other
                    guarantor  that  Vanguard  deems  acceptable.  A   SIGNATURE
                    GUARANTEE CANNOT BE PROVIDED BY A NOTARY PUBLIC.

CERTIFICATES        Share  certificates  will  be issued  upon  request  for all
                    Portfolios  except  the  Short  and  Intermediate-Term  U.S.
                    Treasury  and Intermediate-Term  Corporate Portfolios.  If a
                    certificate is lost, you may incur an expense to replace it.

PURCHASES           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  has  been
                    received.
- --------------------------------------------------------------------------------
WHEN YOUR ACCOUNT   The  TRADE  DATE  is  the  date  on  which  your  account is
WILL BE CREDITED    credited. It is generally the day on which the Fund receives
                    your  investment  in  the  form  of  Federal  Funds  (monies
                    credited  to the Fund's Custodian  Bank by a Federal Reserve
                    Bank). Your trade  date varies according  to your method  of
                    payment for your shares.

                    Purchases  by check  will receive a  trade date  the day the
                    funds are received in good order by Vanguard. Thus, if  your
                    purchase  by check is received by  the close of the New York
                    Stock Exchange  (generally  4:00 p.m.  Eastern  time),  your
                    trade  date is  the business day  your check  is received in
                    good order. If your purchase is received after the close  of
                    the  Exchange, your trade date is the business day following
                    receipt of your check.

                    For purchases by Federal Funds wire or exchange, the Fund is
                    credited immediately  with  Federal  Funds.  Thus,  if  your
                    purchase  by Federal Funds  wire or exchange  is received by
                    the close of  the Exchange, your  trade date is  the day  of
                    receipt. If your purchase is received after the close of the
                    Exchange,  your  trade date  is  the business  day following
                    receipt of your wire or exchange.

                    Your shares are purchased at  the next determined net  asset
                    value after your investment has been received in the form of
                    Federal  Funds.  You will  begin  to earn  dividends  on the
                    calendar day following the trade  date. (For a Friday  trade
                    date, you will begin earning dividends on Saturday.)

                    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

                    normally  mailed,  credited  or  wired--depending  upon  the
                    method  of withdrawal you have previously chosen--within two
                    business days  after  the receipt  of  the request  in  Good
                    Order.

SELLING BY WRITING  You  may withdraw funds from your account by writing a check
A CHECK             payable in  the amount  of $250  or more.  When a  check  is
                    presented  for payment to the Fund's agent, CoreStates Bank,
                    N.A., the Fund will redeem sufficient shares in your account
                    at the next determined net  asset value to cover the  amount
                    of the check.

                    In  order  to  establish  the  checkwriting  option  on your
                    account, all registered shareholders  must sign a  signature
                    card. After your completed signature card is received by the
                    Fund,  an initial supply of checks  will be mailed within 10
                    business days. There is  no charge for  checks or for  their
                    clearance.  CORPORATIONS,  TRUSTS  AND  OTHER  ORGANIZATIONS
                    SHOULD CALL OUR CLIENT SERVICES DEPARTMENT  (1-800-662-2739)
                    BEFORE  SUBMITTING SIGNATURE CARDS,  AS ADDITIONAL DOCUMENTS
                    MAY BE REQUIRED TO ESTABLISH THE CHECKWRITING SERVICE.

                    Before establishing the checkwriting  option, you should  be
                    aware that:

                    1.   Writing a  check (a redemption of  shares) is a taxable
                        event.

                    2.  The Fund does not allow an account to be closed  through
                        the checkwriting option.

                    3.    Vanguard  cannot  guarantee  a  stop  payment  on  the
                    checkwriting option. If you wish  to reverse a stop  payment
                        order, you must do so in writing.

                    4.  Shares held in certificate form cannot be redeemed using
                    the checkwriting option.

                    5.   The Fund reserves the  right to terminate or alter this
                        service at any time.

                    the  redemption proceeds are normally  sent on the following
                    business day.

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

                    Redemption proceeds must be sent to you within seven days of
                    receipt of your request in Good Order.

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

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

                    If the  Board  of  Directors determines  that  it  would  be
                    detrimental  to the  best interests of  the Fund's remaining
                    shareholders to  make  payment in  cash,  the Fund  may  pay
                    redemption  proceeds  of amounts  in  excess of  $250,000 in
                    whole or  in  part by  a  distribution in  kind  of  readily
                    marketable securities.
                    ------------------------------------------------------------
VANGUARD'S AVERAGE  If you make a redemption from a qualifying account, Vanguard
COST STATEMENT      will  send you an Average  Cost Statement which provides you
                    with the tax basis  of the shares  you redeemed. Please  see
                    "Other Vanguard Services" for additional information.
                    ------------------------------------------------------------
MINIMUM ACCOUNT     Due  to  the  relatively high  cost  of  maintaining smaller
BALANCE             accounts, each Portfolio reserves the right to redeem shares
REQUIREMENT         in any account that is below the minimum initial  investment
                    amount  of $3,000.  In addition, if  at any  time your total
                    investment in a Portfolio does not have a value of at  least
                    $1,000,  you may be notified that  the value of your account
                    is below the Fund's minimum account balance requirement. You
                    would  then  be  allowed  60  days  to  make  an  additional
                    investment  before the account is liquidated. Proceeds would
                    be  promptly   paid  to   the  shareholder.   This   minimum
                    requirement   does  not   apply  to   IRAs,  other  Vanguard
                    retirement accounts, and  Uniform Gifts/Transfers to  Minors
                    Act accounts.

                    ------------------------------------------------------------
IMPORTANT EXCHANGE  Before  you  make  an  exchange,  you  should  consider  the
INFORMATION         following:
                    -  Please  read  the  Fund's  prospectus  before  making  an
                    exchange.  For a copy  and for answers  to any questions you
                      may  have,  call   our  Investor  Information   Department
                      (1-800-662-7447).

                    -  An exchange  is treated as  a redemption  and a purchase.
                      Therefore, you could realize a taxable gain or loss on the
                      transaction.

                    - Exchanges are accepted only  if the registrations and  the
                      Taxpayer  Identification numbers  of the  two accounts are
                      identical.

                    -   New   accounts   are    not   currently   accepted    in
                      Vanguard/Windsor Fund.

                    - The redemption price of shares redeemed by exchange is the
                      net   asset  value  next  determined  after  Vanguard  has
                      received all required documentation in Good Order.

                    - When opening a new account by exchange, you must meet  the
                      minimum investment requirement of the new Fund.

                    Every   effort  will  be  made   to  maintain  the  exchange
                    privilege. However, the Fund reserves the right to revise or
                    terminate its provisions, limit the amount of or reject  any
                    exchange, as deemed necessary, at any time.

                    The  exchange privilege is only available in states in which
                    the shares of the Fund  are registered for sale. The  Fund's
                    shares  are currently registered  for sale in  all 50 states
                    and the Fund intends to maintain such registration.
- --------------------------------------------------------------------------------
EXCHANGE PRIVILEGE  The Fund's  exchange privilege  is  not intended  to  afford
LIMITATIONS         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.
</TABLE>

                                                                              37
<PAGE>
<TABLE>
<S>                 <C>
                    Exchange activity will not be deemed excessive if limited to
                    TWO  SUBSTANTIVE  EXCHANGE  REDEMPTIONS  (AT  LEAST  30 DAYS
                    APART) from  a Portfolio  during  any twelve  month  period.
                    Notwithstanding  these  limitations, the  Fund  reserves the
                    right to  reject any  purchase request  (including  exchange
                    purchases from other Vanguard portfolios) that is reasonably
                    deemed to be disruptive to efficient portfolio management.
- --------------------------------------------------------------------------------
IMPORTANT           The   ability   to   initiate   redemptions   (except   wire
INFORMATION ABOUT   redemptions) and  exchanges  by telephone  is  automatically
TELEPHONE           established  on your  account unless you  request in writing
TRANSACTIONS        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 in  which
                       the  account is registered; and  (iv) the Social Security
                       or Taxpayer Identification number listed on the account.

                    2. PAYMENT POLICY. The proceeds of any telephone  redemption
                    by  mail will be  made payable to  the registered shareowner
                       and mailed to the address of record, only. 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. If Vanguard  fails to follow
                    reasonable security  procedures, it  may be  liable for  any
                    losses  resulting from unauthorized  or fraudulent telephone
                    transactions on your account.
