INVESTMENT 
OBJECTIVE AND 
POLICIES            Vanguard California Tax-Free Fund (the "Fund") is an
                    open-end non-diversified investment company that seeks to
                    provide income that is exempt from federal and California
                    State personal income taxes. The Fund will invest
                    primarily in securities issued by California state and
                    local governments and public financing authorities, but
                    may also invest in securities of issuers other than
                    California and its political subdivisions. Although the
                    Fund invests in high-quality instruments, the shares of
                    the Fund are not insured or guaranteed by the U.S.
                    Government. The Fund consists of a Money Market Portfolio,
                    an Insured Intermediate-Term Portfolio and an Insured
                    Long-Term Portfolio, each of which has distinct investment
                    objectives and policies. The Portfolios are available only
                    to California residents. The Money Market Portfolio seeks
                    to maintain, but does not guarantee, a constant net asset
                    value of $1.00 per share.

                    is offered on a no-load basis (i.e., there are no sales
                    commissions or 12b-1 fees). However, the Fund incurs
                    expenses for investment advisory, management,
                    administrative, and distribution services.

                                 HIGHLIGHTS
   
OBJECTIVES AND
POLICIES            Vanguard California Tax-Free Fund (the "Fund") is a
                    no-load, open-end non-diversified investment company
                    whose objective is to provide investors with income that
                    is exempt from federal and California personal income
                    taxes. The Fund consists of three separate Portfolios,
                    each of which invests in California municipal securities
                    within prescribed maturity and quality standards. There is
                    no assurance, however, that the Fund will achieve its
                    stated objective.                                   Page 9
    

- -------------------------------------------------------------------------------
THREE SEPARATE 
PORTFOLIOS          Investors may choose from three separate Portfolios of the
                    Fund:

                    Money Market Portfolio--invests in high-quality California
                    municipal securities with a dollar-weighted average
                    maturity of 90 days or less and seeks to maintain a stable
                    $1.00 share price. An investment in the Money Market
                    Portfolio is neither insured nor guaranteed by the U.S.
                    Government, and there is no assurance that the Portfolio
                    will be able to maintain a stable net asset value of $1.00
                    per share.

                    Insured Intermediate-Term Portfolio--invests in insured
                    California municipal securities with a dollar-weighted
                    average maturity of 7 to 12 years.

                    Insured Long-Term Portfolio--invests in insured California
                    municipal securities with a dollar-weighted average
                    maturity of 15 to 25 years.                          Page 9
- -------------------------------------------------------------------------------
RISK 
CHARACTERISTICS     The three Portfolios of the Fund differ significantly in
                    terms of interest rate risk. Interest rate risk is the
                    potential for fluctuations in the principal value of a
                    bond investment caused by changes in market interest
                    rates. It depends chiefly on the average maturity of a
                    Portfolio's securities.


                    The Money Market Portfolio, which is expected to maintain
                    a stable $1.00 share price, provides minimal exposure to
                    interest rate risk. In contrast, share prices of the
                    Insured Intermediate-Term and Insured Long-Term Portfolios
                    will generally fluctuate as interest rates change. In
                    relative terms, share price fluctuations are expected to
                    be medium for the Insured Intermediate-Term Portfolio and
                    high for the Insured Long-Term Portfolio.           Page 12
- -------------------------------------------------------------------------------

THE VANGUARD 
GROUP               The Fund is a member of The Vanguard Group of Investment
                    Companies, a group of more than 30 investment companies
                    with more than 90 distinct investment portfolios and total
                    assets in excess of $190 billion. The Vanguard Group, Inc.
                    ("Vanguard"), a subsidiary jointly owned by the Vanguard
                    Funds, provides all corporate management, administrative,
                    distribution and shareholder accounting services on an
                    at-cost basis to the Funds in the Group.           Page 22
- -------------------------------------------------------------------------------
INVESTMENT 
ADVISER             The Fund receives investment advisory services on an
                    at-cost basis from an experienced investment management
                    staff employed directly by Vanguard. As a result, the Fund
                    receives its investment advisory services at a
                    substantially lower cost than would be possible if the
                    Fund paid an investment advisory fee to an external
                    investment adviser.                                Page 23

DIVIDEND POLICY     Each Portfolio declares a dividend based on its ordinary
                    income each business day. Dividends are paid monthly and
                    may be received in cash or reinvested in additional
                    shares.                                            Page 23
- -------------------------------------------------------------------------------
   
TAXES               Shareholders pay no federal or California personal income
                    taxes on tax-exempt dividends paid by the Fund's
                    Portfolios. Capital gains distributions from the Fund are
                    subject to federal income tax, as well as state and local
                    taxes if applicable. However, part or all of any gain
                    realized by the Fund on the disposition of securities
                    purchased at a market discounted price above a certain
                    nominal or de minimus amount will be subject to federal
                    income tax as ordinary income (see page 16). Although the
                    Fund seeks to avoid taxable income, shareholders would be
                    responsible for any taxes due if taxable income were
                    realized. Also, while not presently the case, it is
                    possible that a portion of the tax-exempt dividends paid
                    by the Fund may be a tax preference item for purposes of
                    the alternative minimum tax.                       Page 23

PURCHASING 
SHARES              If you are a California resident, you may purchase shares
                    by mail, wire or exchange from another Vanguard Fund. The
                    minimum initial investment is $3,000 per Portfolio; the
                    minimum for subsequent investments is $100. There are no
                    sales commissions or 12b-1 fees.                   Page 28
- -------------------------------------------------------------------------------
SELLING SHARES      You may redeem shares of each Portfolio by mail,
                    telephone, wire or check. 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 (except the Money Market Portfolio's) is
                    expected to fluctuate, and may at redemption be more or
                    less than at the time of initial purchase, resulting in a
                    gain or loss.                                      Page 32

SPECIAL 
CONSIDERATIONS      (1) The value of a Portfolio's municipal securities is
                    expected to fluctuate inversely with interest rates. In
                    general, if interest rates rise, municipal bond prices
                    fall; if interest rates fall, bond prices rise. In
                    addition, for a given change in interest rates, bonds of
                    longer maturities fluctuate more in value than bonds of
                    shorter maturities. Thus, you should expect that each
                    Portfolio's share price (except the Money Market
                    Portfolio's) will vary as interest rates change, and that
                    a Portfolio with a longer maturity will fluctuate more
                    than a Portfolio with a shorter maturity.          Page 12

                    (2) From time to time Congress has considered proposals to
                    restrict or eliminate the tax-exempt status of municipal
                    securities. If such proposals were enacted in the future,
                    each Portfolio would reconsider its investment objectives
                    and policies.                                       Page 9

                    (3) Each Portfolio (except the Money Market Portfolio) may
                    invest a portion of its assets in futures contracts and
                    options.                                           Page 20

                    (4) The Money Market and Insured Long-term Portfolios may
                    invest up to 20% of their assets in short-term
                    non-California municipal securities or in taxable
                    short-term securities. The Intermediate Portfolio may
                    invest up to 35% of its assets in such securities.  Page 9

                    (5) Each Portfolio may purchase municipal obligations on a
                    when-issued basis. Securities purchased on a when-issued
                    basis may decline or appreciate in market value prior to
                    their actual delivery to a Portfolio.              Page 19

                    (6) Each Portfolio may lend its investment securities.
                                                                       Page 19

                    (7) Each Portfolio may invest in municipal lease
                    obligations.                                       Page 20

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

                    In accordance with industry guidelines set forth by the
                    U.S. Securities and Exchange Commission, the "30-day
                    yield" of the Insured Intermediate-Term and Insured
                    Long-Term Portfolios is calculated by dividing the net
                    investment income per share earned during a 30-day period
                    by the net asset value per share on the last day of the
                    period. Net investment income includes interest and
                    dividend income earned on a Portfolio's securities; it is
                    net of all expenses and all recurring and nonrecurring
                    charges that have been applied to all shareholder
                    accounts. The yield calculation assumes that the net
                    investment income earned over 30 days is compounded
                    monthly for six months and then annualized.

                    The "seven-day" or "current" yield of the Money Market
                    Portfolio reflects the income earned by a hypothetical
                    account in the Portfolio during a seven-day

<PAGE>


                    period, expressed as an annual percentage rate. The
                    "effective yield" of the Money Market Portfolio assumes
                    that the income over the seven-day period is reinvested
                    weekly, resulting in a slightly higher stated yield
                    through compounding.

                    Methods used to calculate advertised yields are
                    standardized for money market and bond funds. However,
                    these methods differ from the accounting methods used by
                    the Portfolios to maintain their books and records, and so
                    advertised yields may not fully reflect the income paid to
                    an investor's account or the yield reported in the Fund's
                    Annual Report to Shareholders.

INVESTMENT          The Fund consists of the California Money Market
OBJECTIVES          Portfolio, the California Insured Intermediate-Term
                    Portfolio and the California Insured Long-Term Portfolio,
The Fund seeks to   each of which has a distinct investment objective.

from federal and      is to provide investors with income that is exempt from
California income     both federal and California State personal income
taxes                 taxes. The Portfolio also seeks to maintain, but does
                      not guarantee, a constant net asset value of $1.00 per
                      share. Although the Portfolio invests in high quality
                      instruments, the shares of the Portfolio are not
                      insured or guaranteed by the U.S. Government.

                    o The objective of the California Insured
                      Intermediate-Term and Insured Long-Term Portfolios is
                      to provide investors with a high level of income that
                      is exempt from federal and California personal income
                      taxes.

                    The three Portfolios of the Fund are available only to
                    investors who reside in California. There is no assurance
                    that the Portfolios will achieve their stated objectives.

                    The investment objective of each Portfolio is fundamental
                    and so may not be changed without the approval of a
                    majority of the Fund's shareholders.

- -------------------------------------------------------------------------------
INVESTMENT 
POLICIES            Each Portfolio of the Fund will invest at least 80% of its
                    net assets in California municipal securities, exclusive
                    of California AMT bonds (see "Implementation of
                    Policies"). California municipal securities are debt
                    obligations issued by California state and local
                    governments and public financing authorities that provide
                    interest income that is exempt from both federal and
                    California personal income taxes. The California municipal
                    securities described above, may include securities in
                    which the tax-exempt interest rate is determined by an
                    index, swap or some other formula. Although each Portfolio
                    invests primarily in California municipal obligations, the
                    three Portfolios differ in terms of credit quality and
                    maturity standards. 

The Money Market    Under normal circumstances, the California Money Market
Portfolio will      Portfolio will invest at least 80% of its net assets in
invest in           the following high-quality, short-term California
short-term          municipal securities:

                       A-1+ or A-1 by Standard & Poor's;


                     o Municipal bonds, including derivative securities, with
                       an effective maturity of 13 months or less rated a
                       minimum of Aa by Moody's or AA by Standard & Poor's;
                       and

                     o Unrated municipal notes considered by the Board of
                       Trustees to be comparable in credit quality to
                       securities rated MIG-1 by Moody's or SP-1+ or SP-1 by
                       Standard & Poor's.
 

                    In addition, up to 10% of the Money Market Portfolio's net
                    assets may be invested in "restricted" money market
                    securities, which are not freely marketable or which are
                    subject to restrictions on disposition under the
                    Securities Act of 1933.


                    In seeking to provide a stable share price of $1.00, the
                    California Money Market Portfolio is expected to maintain
                    a dollar-weighted average maturity of 90 days or less, and
                    will purchase securities with an effective maturity of 13
                    months or less which are eligible for purchase under Rule
                    2a-7 of the Investment Company Act of 1940 (the "1940
                    Act").

                    Normally, the California Money Market Portfolio will seek
                    to invest substantially all of its assets in the
                    short-term California municipal obligations listed above.
                    However, under certain circumstances, such as a temporary
                    decline in the issuance of California obligations, the
                    Portfolio may invest up to 20% of its net assets in
                    short-term municipal securities issued outside of
                    California (the income from which may be subject to
                    California income taxes) and certain taxable fixed-income
                    securities (the income from which may be subject to
                    federal and California income taxes).

                    Subject to the same 20% limit, the Portfolio is also
                    authorized to invest in short-term California AMT bonds.
                    The income from California AMT bonds is exempt from
                    regular federal and California income taxes, but may be a
                    tax preference item for purposes of the federal
                    alternative minimum tax (see "Implementation of
                    Policies").

                    Any non-California securities or California AMT bonds
                    purchased by the Portfolio will be subject to the same
                    ratings requirements as described above.

                    Under unusual circumstances, such as a national financial
                    emergency, the Portfolio reserves the right to invest more
                    than 20% of its net assets in securities other than
                    California municipal obligations. In most instances,
                    however, the California Money Market Portfolio will seek
                    to avoid such holdings in an effort to provide income that
                    is fully exempt from federal and California personal
                    income taxes.

                    Insured municipal bonds are those for which scheduled
                    payments of interest and principal are guaranteed by a
                    private (non-governmental) insurance company. The
                    insurance feature does not guarantee the market value of
                    the municipal bonds or the value of the shares of the
                    California Insured Intermediate-Term Portfolio or the
                    California Insured Long-Term Portfolio. The insurance
                    refers to the face or par value of the securities in a
                    Portfolio. See "Implementation of Policies" for a
                    description of the insurance feature of the Portfolios.

                    Any uninsured securities purchased by the California
                    Insured Intermediate-Term Portfolio or the California
                    Insured Long-Term Portfolio will be rated a minimum of
                    "investment grade" by a nationally recognized statistical
                    rating organization, or if unrated, will be deemed to be
                    of comparable quality by the investment adviser.

                    The California Insured Intermediate-Term Portfolio is
                    expected to maintain a dollar-weighted average maturity
                    between 7 and 12 years.

                    The California Insured Long-Term  Portfolio is expected to
                    maintain a dollar-weighted average maturity between 15 and
                    25 years.

                    Bonds with longer maturities usually offer higher yields,
                    but are also subject to greater market fluctuations as
                    interest rates change. See the section entitled
                    "Investment Risks" for further information.

                    Normally, the Insured Intermediate-Term and Insured
                    Long-Term Portfolios seek to invest most of their assets
                    in insured California municipal securities. However, under
                    certain circumstances, such as a temporary decline in the
                    issuance of California obligations, the Portfolios may
                    invest in other types of securities. The Insured
                    Intermediate-Term Portfolio may invest up to 35% of its
                    assets in any combination of the securities listed below;
                    while the Insured Long-Term Portfolio may invest up to 20%
                    of its assets in any combination of the securities listed
                    below:

                    o  Uninsured, intermediate-term or long-term California
                       municipal securities, respectively, rated a minimum of
                       Aa by Moody's or AA by Standard & Poor's;

                    o  Uninsured, short-term municipal securities, issued in
                       California or in other states, with the same quality
                       standards that apply for the California Money Market
                       Portfolio; and

                    o  Certain taxable securities, subject to the same quality
                       standards that apply to the California Money Market
                       Portfolio, including U.S. Government securities.

                    In such cases, a portion of a Portfolio's income may be
                    subject to California income taxes, federal income taxes,
                    or both.

                    Subject to a 20% of net assets limit, the Portfolios are
                    also authorized to invest in California AMT bonds. The
                    income from California AMT bonds is exempt from federal
                    and California income taxes, but may be a tax preference
                    item for purposes of the federal alternative minimum tax
                    (see "Implementation of Policies").

                                                                            11

                    Under unusual circumstances, such as a national financial
                    emergency, the Portfolios reserve the right to invest more
                    than 20% of their assets in securities other than
                    California municipal obligations. In most instances,
                    however, the California Insured Intermediate-Term and
                    Insured Long-Term Portfolios will seek to avoid such
                    holdings in an effort to provide income that is fully
                    exempt from federal and California personal income taxes.

                    In the event that a security held by the California
                    Insured Intermediate-Term Portfolio or the California
                    Insured Long-Term Portfolio is downgraded, the Portfolio
                    may continue to hold such security until the investment
                    adviser determines that it should be sold.


Each Portfolio      Although the Fund is organized as a non-diversified       
will diversify      investment company, each Portfolio of the Fund intends to 
its holdings        diversify its holdings of California municipal securities 
                    by complying with Subchapter M of the Internal Revenue
                    Code. In part, Subchapter M requires that, at the close of
                    each quarter of the taxable year, those issuers which
                    represent more than 5% of each Portfolio's assets be
                    limited in aggregate to 50% of the Portfolio, and that no
                    one issue exceed 25% of the Portfolio's total assets. As
                    of November 30, 1995, the California Money Market
                    Portfolio held securities of 49 issuers, with the largest
                    holding representing 9.95% of the Portfolio's assets; the
                    California Insured Long-Term Portfolio held securities of
                    96 issuers, with the largest holding representing 4.8% of
                    the Portfolio's assets. The California Insured
                    Intermediate-Term Portfolio held securities of 57 issuers,
                    with the largest holding representing 4.3% of the
                    Portfolio's assets.


                    Under California law, in order to be eligible to pay
                    dividends to California residents which will be exempt
                    from California personal income taxes, a mutual fund must,
                    at the close of each quarter, have at least 50% of the
                    value of its total assets invested in obligations the
                    interest on which is exempt from personal income taxation
                    under California law.


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


                    The Fund's policy of investing at least 80% of its assets
                    in California's municipal securities (excluding AMT bonds)
                    under normal circumstances is fundamental and may not be
                    changed without shareholder approval. The other investment
                    policies described above are not fundamental and so may be
                    changed by the Board of Trustees without shareholder
                    approval.

INVESTMENT          As mutual funds investing in municipal securities, the     
RISKS               three Portfolios of the Fund are subject to interest rate, 
                    credit, call, income and manager risk.  
                  
The Fund is         Interest rate risk is the potential for fluctuations in    
subject to          bond prices due to changing interest rates. In general,    
interest rate,      bond prices vary inversely with interest rates. If          
credit, call,       interest rates rise, bond prices generally decline; if      
income and          interest rates fall, bond prices generally rise. In         
manager risk        addition, for a given change in interest rates,             
                    longer-maturity bonds exhibit greater price fluctuations    
                    than shorter-maturity bonds. To compensate investors for    
                    this risk, longer-maturity bonds generally offer higher     
                    yields than shorter-maturity bonds, other factors,          
                    including credit quality, being equal. Interest rate

                    risk may be increased or decreased when a portfolio
                    initiates or purchases derivative California municipal
                    securities. Such derivative securities rely on
                    sophisticated interest rate calculation mechanisms. For
                    certain types of derivative bonds, the magnitude of
                    increases and decreases in their price may be
                    proportionately larger or smaller than, or inverse to, the
                    price changes that broad market interest rate fluctuations
                    would produce in long-term bonds.

                    Credit 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
                    credit quality of its underlying securities. In general,
                    the lower the credit quality of a Portfolio's municipal
                    securities, the higher a Portfolio's yield, all other
                    factors such as maturity being equal.

                    Call risk is the possibility that, during periods of
                    falling interest rates, a municipal security with a high
                    stated interest rate will be prepaid (or "called") prior
                    to its expected maturity date. As a result, a Portfolio
                    will be required to invest the unanticipated proceeds at
                    lower interest rates and the Portfolio's income may
                    decline. Call provisions are most common for intermediate-
                    and long-term municipal bonds.

                    Income risk is the potential for a decline in a
                    Portfolio's income due to falling market interest rates.
                    Because a Portfolio's income is based on interest rates,
                    which can fluctuate substantially over short periods,
                    income risk is expected to vary from Portfolio to
                    Portfolio.

The Fund is subject Finally, the investment adviser manages the Fund's         
to manager risk     Portfolios according to the traditional methods of         
                    "active" investment management, which involve the buying
                    and selling of securities based upon economic, financial
                    and market analysis and investment judgment. Manager risk
                    refers to the possibility that the Fund's investment
                    adviser may fail to execute a Portfolio's investment
                    strategy effectively. As a result, a Portfolio may fail to
                    achieve its stated objective.

                    This chart is intended to provide you with general
                    guidelines for evaluating the effect of interest rate
                    changes on the California Insured Intermediate-Term and
                    Insured Long-Term Portfolios and determining the degree of
                    interest rate risk you may be willing to assume.


Credit risk is      The California Money Market Portfolio invests primarily in  
expected to         high-quality, short-term California municipal securities;  
be low              while the California Insured Intermediate-Term and         
                    Insured Long-Term Portfolios invest primarily in bonds      
                    insured by top-rated insurance companies against the       
                    possible default of an issuer as to the timely payment of   
                    interest and principal. As a result, the average credit     
                    quality of each Portfolio is expected to be very high and   
                    credit risk is expected to be minimal.                      
                                                                                
                    Ordinarily, an investment company concentrating its
                    investments in one state, such as the Fund, would be
                    exposed to greater credit risks than an investment company
                    investing in a nationally diversified portfolio of
                    municipal securities. These risks include possible tax law
                    changes, a deterioration in economic conditions, differing
                    levels of supply and demand for California municipal
                    obligations, and localized natural disasters.

                    To minimize the effects of concentrating its investments
                    in California obligations, each Portfolio of the Fund
                    intends to diversify its holdings by complying with
                    Subchapter M of the Internal Revenue Code. (See
                    "Investment Policies" for a description of the
                    requirements of Subchapter M.) In addition, the
                    high-quality instruments held by the Money Market
                    Portfolio and the use of municipal bond insurance in the
                    Insured Intermediate-Term and Long-Term Portfolios should

WHO SHOULD          The Fund is intended for California residents seeking      
INVEST              income that is exempt from federal and California personal 
                    income taxes. As a rule, tax-free income is attractive to  
California          investors in high federal and California tax brackets. You 
residents           can determine whether tax-exempt or taxable income is more 
sseeking            attractive in your own case by comparing a Portfolio's     
tax-exempt          tax-exempt yield with the yield from a comparable taxable  
income              mutual fund investment. See "How to Compare Tax-Free and   
                    Taxable Yields."                                           

                    Assuming that tax-exempt income is attractive in your own
                    tax bracket, you should base your selection of a Portfolio
                    (or Portfolios) on its expected price volatility and
                    yield, and your own investment objectives, risk
                    preferences and time horizon.

                    The California Money Market Portfolio is intended for
                    investors who are seeking a stable share price and minimal
                    credit risk. The yield on the Portfolio is expected to
                    fluctuate from day-to-day and to be lower on average than
                    the yield from the California Insured Intermediate-Term
                    and Insured Long-Term Portfolios. The California Money
                    Market Portfolio is suitable as a short-term investment
                    vehicle, emphasizing maximum protection of principal.

                    The California Insured Intermediate-Term Portfolio is
                    intended for investors who are willing to accept moderate
                    share price fluctuations in exchange for potentially
                    higher and more durable yields.

                    The California Insured Long-Term Portfolio is intended for
                    investors who are seeking the highest, most durable
                    streams of income and who can tolerate sometimes sharp
                    fluctuations in share price in pursuit of their income
                    objectives. The yield of the Portfolio is expected to be
                    higher, and the level of income provided more stable, than
                    that of the California Money Market and Insured
                    Intermediate-Term Portfolios. However, because of the
                    potential volatility of the Portfolio's shares price, the
                    California Insured Long-Term Portfolio is appropriate only
                    for those investors who can hold their investment over the
                    long term.

                    The Fund is intended to be a long-term investment vehicle
                    and is not designed to provide investors with a means of
                    speculating on short-term market movements. Investors who
                    engage in excessive account activity generate additional
                    costs which are borne by all of the 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

                    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.

HOW TO COMPARE      Before choosing a specific tax-exempt investment, such as   
TAX-FREE AND        a Portfolio of the Fund, you should determine if you would 
TAXABLE YIELDS      be better off with taxable or tax-exempt income in your    
                    tax bracket. To compare taxable and tax-exempt income, you 
                    should first determine your combined federal, state and    
                    local tax bracket. Then you should calculate the "taxable  
                    equivalent yield" for the Portfolio you are considering,   
                    and compare it with the yield of a taxable investment with 
                    similar credit and maturity characteristics.               
                    
                    
                    
                    

                    1. Determine your combined tax bracket. Your combined tax
                    bracket depends on whether you itemize state and local
                    taxes as a deduction on your federal return. If you do not
                    itemize, then your combined tax bracket is the sum of your
                    federal, state and local tax brackets.

                    If you do itemize, then your combined tax bracket is
                    calculated as follows. First, calculate your effective
                    state and local tax bracket using the following formula:

                    (        Federal )                              Effective 
                    ( 100% -  Tax    )     X     State &             State & 
                    (        Bracket )         Local Bracket      Local Bracket 

                    For example, if you are in a 9.3% state and local tax
                    bracket and a 28% federal tax bracket, your effective
                    state and local tax bracket would be 6.7%:
                                  
                                 (100% -- 28%)   X   9.3%   =   6.7%

                    Second, add your effective state and local tax bracket to
                    your federal tax bracket to determine your combined tax
                    bracket:


                     Federal             Effective             Combined 
                       Tax       +        State &        =        Tax 
                     Bracket           Local Bracket            Bracket 
                       28%       +         6.7%          =       34.7%

                    2. Calculate your taxable equivalent yield. The taxable
                    equivalent yield for a Portfolio is based upon the
                    Portfolio's current tax-exempt yield and your combined tax
                    bracket. The formula is:

                          Portfolio's Tax-Exempt Yield 
                       ---------------------------------   =    Your Taxable 
                       100% -- Your Combined Tax Bracket      Equivalent Yield

                    For example, if you are in a combined tax bracket of
                    34.7%, and a Portfolio's tax- free yield is 6%, the
                    Portfolio's taxable equivalent yield would be 9.2%:

                                       6%
                                 -------------   =  9.2%
                                 100% -- 34.7%

                    In this example, you would choose the tax-exempt
                    investment if the 9.2% taxable equivalent yield were
                    greater than the taxable yield from a comparable
                    investment (e.g., a taxable bond fund of comparable
                    maturity and credit quality).

IMPLEMENTATION      The Fund's adviser uses a variety of investment vehicles   
OF POLICIES         to achieve the objective of the Fund.                      
                   
The Fund invests    Each Portfolio of the Fund invests principally in          
in municipal        tax-exempt California municipal securities, which are debt 
bonds, notes and    obligations issued by state and local governments and      
securities derived  public financing authorities that provide interest income  
from municipal      that is exempt from federal and California personal income 
bonds and notes     taxes. Municipal securities include both municipal bonds   
                    (those securities with maturities of five years or more)   
                    municipal notes (those securities with maturities of less  
                    than five years) and derivative securities (for example,   
                    those securities for which a maturity may have been        
                    shortened by a demand feature).                            

                    Municipal bonds are issued for a wide variety of reasons:
                    to construct public facilities, such as airports,
                    highways, bridges, schools, hospitals, housing, mass
                    transportation, streets, water and sewer works; to obtain
                    funds for operating expenses; to refund outstanding
                    municipal obligations; and to loan funds to various public
                    institutions and facilities. Certain industrial
                    development bonds are also considered municipal bonds if
                    their interest is exempt from federal income tax.
                    Industrial development bonds are issued by, or on behalf
                    of, public authorities to obtain funds for various
                    privately-operated manufacturing facilities, housing,
                    sports arenas, convention centers, airports, mass
                    transportation systems, and water, gas or sewage works.

                    General obligation municipal bonds are secured by the
                    issuer's pledge of full faith, credit and taxing power.
                    Revenue or special tax bonds are payable from the revenues
                    derived from a particular facility or, in some cases, from
                    a special excise or other tax, but not from general tax
                    revenue. Industrial development bonds are ordinarily
                    dependent on the credit quality of a private authority.

                    Municipal notes are issued to meet the short-term funding
                    requirements of local, regional and state governments.
                    Municipal notes include tax anticipation notes, bond
                    anticipation notes, revenue anticipation notes, tax and
                    revenue anticipation notes, construction loan notes,
                    short-term discount notes, tax-exempt commercial paper,
                    demand notes, and similar instruments. Demand notes permit
                    an investor (such as the Fund) to demand from the issuer
                    payment of principal plus accrued interest upon a
                    specified number of days' notice.

The Fund may        Although neither does so at present, each Portfolio of the 
invest in AMT       Fund is authorized to invest up to 20% of its assets in    
bonds               so-called "AMT" bonds. AMT bonds are tax- exempt "private  
                    activity" bonds issued after August 7, 1986, whose         
                    proceeds are directed at least in part to a private,        
                    for-profit organization. While the income from AMT bonds    
                    is exempt from regular federal income tax, it is a tax      


                                                                            17

                    preference item for purposes of the alternative minimum
                    tax. The alternative minimum tax is a special separate tax
                    that applies to a limited number of taxpayers who have
                    certain adjustments to income or tax preference items.

The Fund may        The Fund may invest in "Market Discount" bonds when, in

Discount bonds      advantageous to the Fund's shareholders. A Market Discount 
                    bond is a bond purchased at a discount from its original   
                    issue price after April 30, 1993 and with a maturity in    
                    excess of one year from its issue date. In certain         
                    circumstances, disposition of a Market Discount bond will  
                    result in taxable ordinary income to the extent of any     
                    gain realized.                                             
                    

                    Although the objective of the Fund is to provide income
                    free of federal income tax, certain market conditions may
                    make Market Discount bonds desirable investments. The Fund
                    will purchase Market Discount bonds only if the Fund's
                    adviser expects that the purchase of these investments on
                    an after-tax basis will enhance the Fund's total return.


Three types of      To provide an added level of credit protection, the         
insurance may be    California Insured Intermediate-Term and Insured Long-Term 
used in the         Portfolios use three types of insurance: new issue, mutual 
Insured             fund and secondary market insurance. A new issue policy is 
Intermediate-Term   purchased by a bond issuer who wishes to increase the      
and Insured         credit rating of a security. By paying a premium and       
Long-Term           meeting the insurer's underwriting standards, the bond     
Portfolios          issuer is able to obtain a high credit rating for the      
                    security (usually Aaa from Moody's or AAA from Standard &  
                    Poor's). New issue insurance policies are non-cancellable  
                    and continue in force as long as the bonds are             
                    outstanding.                                               
                    

                    A mutual fund insurance policy may be used to guarantee
                    specific bonds only while owned by a mutual fund. The
                    Insured Intermediate-Term and Insured Long- Term
                    Portfolios of the Fund have obtained mutual fund insurance
                    policies from Financial Guaranty Insurance Company
                    ("Financial Guaranty"), a AAA-rated insurance company.
                    Based upon the expected composition of each Portfolio, the
                    annual premiums for the policies are likely to range from
                    0.20% to 0.40% of the principal value of the bonds insured
                    under the policy, thereby reducing the Portfolios' current
                    yield.

                    A secondary market insurance policy is purchased by an
                    investor (such as the Insured Intermediate-Term or Insured
                    Long-Term Portfolio) subsequent to the bond's original
                    issuance and generally insures a particular bond for the
                    remainder of its term. A Portfolio may purchase bonds
                    which have already been insured under a secondary market
                    insurance policy by a prior investor, or the Portfolio may
                    itself purchase such a policy from Financial Guaranty for
                    bonds that are currently uninsured.


                    An insured municipal bond in either of the Portfolios will
                    typically be covered by only one of the three policies.
                    For instance, if a bond is already covered by a new issue
                    insurance policy or a secondary market insurance policy,
                    then that security will not be insured under a Portfolio's
                    mutual fund insurance policy. All of the insurance
                    policies used by the Portfolios will be obtained only from
                    insurance companies rated Aaa by Moody's or AAA by

                    companies will have the effect of making the insured bonds
                    equivalent in quality to AAA-rated bonds.

The Insured         Each Portfolio of the Fund observes strict maturity        
Intermediate-Term   guidelines as set forth in detail under "Investment        
and Insured Long-   Policies." These maturity standards are specified in terms 
Term Portfolios     of a Portfolio's average dollar-weighted maturity. From    
may report an       time to time, however, the Fund may also report an         
effective average   effective average dollar-weighted maturity for the Insured 
dollar-weighted     Intermediate-Term or Insured Long-Term Portfolio, which    
maturity            reflects, among other items, the likelihood that a         
                    municipal bond or note held by the Portfolio may be        
                    redeemed or "called" prior to its stated maturity date.    
                    For example, if the Insured Long-Term Portfolio consists   
                    entirely of 20-year bonds, some of which may be "called"   
                    prior to their stated maturity in 20 years, the            
                    Portfolio's average weighted maturity will be 20 years,    
                    while its effective average maturity will be shorter.      
                    
                    A Portfolio's effective average weighted maturity will be
                    influenced by bond market conditions, and so may vary from
                    day to day, even if no change has been made to the
                    Portfolio's underlying investment securities. For example,
                    if interest rates decline, a greater proportion of a
                    Portfolio's securities may be subject to call (redemption)
                    prior to their stated maturity. As a result, reflecting
                    this increased call risk, the effective average maturity
                    of a Portfolio will shorten, independent of actual
                    purchases or sales of portfolio securities.

Temporary           Except as described on page 10, each Portfolio will not    
Investments         invest in securities other than municipal bonds, except    
                    that each Portfolio may make temporary investments for     
                    temporary defensive purposes (and subject to the quality   
                    standards described on page 11) in (a) notes issued by or  
                    on behalf of municipal or corporate issuers, obligations   
                    of the U.S. Government and its agencies, commercial paper  
                    and bank certificates of deposit; (b) investment companies 
                    investing in such securities which have investment         
                    objectives consistent with those of the Portfolio to the   
                    extent permitted by the Investment Company Act of 1940;    
                    and (c) any such securities or municipal bonds subject to  
                    repurchase agreements.                                     
 
The Fund may        Each Portfolio may purchase tax-exempt securities on a     
purchase            "when-issued" basis. In buying "when-issued" securities, a 
when-issued         Portfolio commits to buy securities at a certain price     
securities          even though the securities may not be delivered for up to  
                    45 days. The Portfolio pays for the securities and begins  
                    earning interest when the securities are actually          
                    delivered. As a consequence, it is possible that the       
                    market price of the securities at the time of delivery may 
                    be higher or lower than the purchase price.

The Fund may        Each Portfolio may lend its investment securities for     
lend its            either short-term or long-term purposes to qualified      
securities          institutional investors for the purpose of realizing     
                    additional net investment 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. Income derived from the lending of securities  
                    is not tax-exempt, and a portion of the tax-exempt         
                   
                   
                   
                   
  
                                                                            19

                    interest earned when a municipal security is on loan must
                    be characterized as taxable income.

                    Therefore, each Portfolio will limit such activity in
                    accordance with its investment objective.

The Fund may        Each Portfolio may purchase municipal lease obligations,   
invest in           which are securities issued by state and local governments 
municipal lease     to acquire land, equipment and facilities. These           
obligations         obligations typically are not backed by the issuing        
                    municipality's full authority to assess taxes to meet its  
                    debt obligations. If the issuing authority fails to make   
                    the appropriations necessary to cover lease payments, then 
                    the lease may terminate, with the possibility of default   
                    on the lease obligation and loss to investors.             


Derivative          Derivatives are instruments whose values are linked to or  
Investing           derived from an underlying security or index. The most     
                    common and conventional types of derivative securities are 
                    futures and options.                                       
                    
The Insured         The California Insured Intermediate-Term and Insured       
Intermediate-Term   Long-Term Portfolios may invest in conventional derivative 
and Insured         securities including futures contracts and options, but    
Long-Term           only to a limited extent. The Portfolios may enter into    
Portfolios may      futures contracts provided that not more than 5% of its    
invest in           assets are required as a futures deposit; in addition, a   
derivative          Portfolio may enter into futures contracts and options     
securities          transactions to the extent that obligations under such     
                    contracts or transactions represent not more than 20% of   
                    the Portfolio's assets.                                    
                    
                    Futures contracts and options may be used for several
                    common fund management strategies: to maintain cash
                    reserves while simulating full investment, to facilitate
                    trading, to reduce transaction costs, or to seek higher
                    investment returns when a specific futures contract is
                    priced more attractively than other futures contracts or
                    the underlying security or index. The Portfolios may not
                    use futures contracts or options transactions to leverage
                    its assets.
                                 
                    For example, in order to remain fully invested in bonds
                    while maintaining liquidity to meet potential shareholder
                    redemptions, the California Insured Intermediate-Term and
                    Long-Term Portfolios may invest a portion of its assets in
                    a bond futures contract. Because futures contracts only
                    require a small initial margin deposit, the Portfolios
                    would then be able to maintain a cash reserve to meet
                    potential redemptions, while at the same time remaining
                    fully invested. Also, because the transaction costs of
                    futures and options may be lower than the cost of
                    investing in bonds directly, it is expected that the use
                    of futures contracts and options may reduce the
                    Portfolios' total transaction costs.

                    The Portfolios may use futures contracts for bona fide
                    "hedging" purposes. In executing a hedge, a manager sells,
                    for example, municipal bond futures contracts to protect
                    against a decline in the bond market. If the market drops,
                    the value of the futures position will rise, thereby
                    offsetting the decline in value of the portfolio's bond
                    holdings.
                                 
                    The Portfolios may invest in partnerships and grantor
                    trust derivative products. However, prior to the purchase
                    of such security, a determination must be made by the
                    Portfolio that the inherent risk of the partnership or
                    grantor trust derivative product is minimal.

Futures contracts   The primary risks associated with the use of futures       
and options pose    contracts and options are: (i) imperfect correlation       
risks               between 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 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   
                    transactions on a national exchange with an active and     
                    liquid secondary market.                                   
                    
                    The risk of loss in trading futures contracts in some
                    strategies can be substantial, due both to the low margin
                    deposits required and the extremely high degree of
                    leverage involved in futures pricing. As a result, a
                    relatively small price movement in a futures contract may
                    result in immediate and substantial loss (or gain) to the
                    investor. When investing in futures contracts, a Portfolio
                    will segregate cash or cash equivalents in the amount of
                    the underlying obligation.

Partnerships and    The primary risks associated with partnerships and grantor 
grantor trusts      trust derivative products are (i) the possibility of a tax 
pose certain        ruling which affects the status of the state or federal    
risks               opinions which are necessary to support the issuance of    
                    the derivative; (ii) the possibility that the tender       
                    option on a security could be withdrawn upon the           
                    occurrence of certain events and (iii) the possible lack   
                    of a liquid secondary market for the securities. The       
                    Portfolios will attempt to minimize the risks of           
                    partnership and grantor trust derivative products by       
                    carefully selecting which securities to purchase and by    
                    constantly monitoring securities held by the Portfolios.

INVESTMENT          The Fund has adopted certain limitations designed to      
LIMITATIONS         reduce its exposure to specific situations. These         
                    limitations include the following:                        

The Fund has        (a) California Insured Intermediate-Term Portfolio         
adopted certain         will invest a minimum of 65% of its net assets in      
fundamental             insured municipal bonds, the interest on which is      
limitations             exempt from federal and California personal income     
                        taxes, except that it may make temporary investments   
                        as described in "Implementation of Policies." 
                    
                    (b) The California Insured Long-Term Portfolio will invest
                        a minimum of 80% of its net assets in insured
                        municipal bonds, the interest on which is exempt from
                        federal and California personal income taxes, except
                        that it may make temporary investments as described in

                    (c) The California Money Market Portfolio "Implementation
                        of Policies." will invest a minimum of 80% of its net
                        assets in short-term municipal securities, the
                        interest on which is exempt from federal and
                        California personal income taxes, except that it may
                        make temporary investments as described in
                        "Implementation of Policies."

                    (d) At the close of each quarter of the taxable year,
                        those issuers which represent more than 5% of a
                        Portfolio's assets will be limited in aggregate to 50%
                        of the assets of that Portfolio (except U.S.
                        Government and cash items, as defined in the Internal
                        Revenue Code (the "Code")).


                                                                            21
<PAGE>

                    (e) Each Portfolio will limit the aggregate value of
                        holdings of a single issuer (except U.S. Government
                        and cash items as defined in the Code) to a maximum of
                        25% of the Portfolio's total assets. For the purposes
                        of this limitation, identification of the issuer will
                        be based on a determination of the source of assets
                        and revenues committed to meeting interest and
                        principal payments on each security.
                                 
                    (f) A Portfolio will not borrow money except for temporary
                        or emergency purposes, and then not in excess of 10%
                        of the Portfolio's total assets. The Portfolio will
                        repay all borrowings before making additional
                        investments, and the interest paid on such borrowings
                        will reduce income.
                                 
                    (g) A Portfolio will not pledge, mortgage, or hypothecate 
                        more than 10% of its total assets.

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

MANAGEMENT          The Fund is a member of The Vanguard Group of Investment   
OF THE FUND         Companies, a family of more than 30 investment companies   
                    with more than 90 distinct investment portfolios and total 
Vanguard            assets in excess of $190 billion. Through their            
administers and     jointly-owned subsidiary, The Vanguard Group, Inc.         
distributes the     ("Vanguard"), the Fund and the other funds in the Group    
Fund                obtain at cost virtually all of their corporate            
                    management, administrative, shareholder accounting and     
                    distribution services. Vanguard also provides investment   
                    advisory services on an at-cost basis to certain Vanguard  
                    funds. As a result of Vanguard's unique corporate          
                    structure, the Vanguard funds have costs substantially     
                    lower than those of most competing mutual funds. In 1995,  
                    the average expense ratio (annual costs including advisory 
                    fees divided by total net assets) for the Vanguard funds   
                    amounted to approximately .31% compared to an average of   
                    1.11% for the mutual fund industry (data provided by       
                    Lipper Analytical Services).                               

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

                    Vanguard employs a supporting staff of management and
                    administrative personnel needed to provide the requisite
                    services to the funds and also furnishes the funds with
                    necessary office space, furnishings and equipment. Each
                    fund pays its share of Vanguard's total expenses, which
                    are allocated among the funds under methods approved by
                    the Board of Trustees 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.

investments         Total assets under management by Vanguard's Fixed Income   
                    Group were approximately $66 billion as of December 31,    
                    1995. The Fixed Income Group is supervised by the Officers 
                    of the Fund. Ian A. MacKinnon, Senior Vice President of    
                    Vanguard, has been in charge of the Group since its        
                    inception in 1981. Mr. MacKinnon is responsible for        
                    setting the broad investment strategies employed by the    
                    Fund, and for overseeing the portfolio managers who        
                    implement these strategies on a day-to-day basis.

                      manager of the California Insured Intermediate-Term and
                      Insured Long-Term Portfolios. Mr. Smith has managed the
                      Insured Intermediate-Term Portfolio since its inception in
                      1994, and began managing the Insured Long-Term Portfolio
                      in 1992. (Previously, the Insured Long-Term Portfolio was
                      managed by David Hamlin of the Fixed Income Group.) For 3
                      years prior to joining Vanguard, Mr. Smith was associated
                      with another mutual fund advisory firm as a fixed-income
                      portfolio manager.


                    The Fixed Income Group manages the investment and
                    reinvestment of the assets of the Fund's 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
                    Trustees. 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 fixed-income securities and money market
                    instruments; and (c) actual or anticipated movements in
                    the general level of interest rates.

                    Vanguard's Fixed Income Group places all orders for
                    purchases and sales of portfolio securities. Purchases of
                    portfolio securities are made either directly from the
                    issuer or from municipal securities dealers. The Fixed
                    Income Group may sell portfolio securities prior to their
                    maturity if circumstances and considerations warrant and
                    if it believes such dispositions advisable. The Fund's
                    policy of investing in short-term instruments in the
                    California Money Market Portfolio will likely result in
                    significant portfolio turnover. The Fixed Income Group
                    seeks to obtain the best available net price and most
                    favorable execution for all portfolio transactions.

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

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


Dividends will be   Each Portfolio of the Fund intends to continue to qualify  
exempt from federal for taxation as a "regulated investment company" under the 
and California      Internal Revenue Code so that each Portfolio will not be   
income taxes        subject to federal income tax to the extent that its       
                    income is distributed to shareholders. In addition, each   
                    Portfolio intends to invest a sufficient portion of its    
                    assets in municipal bonds and notes so that it will        
                    qualify to pay "exempt-interest dividends" to              
                    shareholders. Such exempt-interest dividends are excluded  
                    from a shareholder's gross income for federal tax          
                    purposes. The Revenue Reconciliation Act enacted during    
                    1993 provides that market discount on tax- exempt bonds    
                    purchased after April 30, 1993 must be taxed as ordinary   
                    income. Accordingly, to the extent that the Fund purchases 
                    such discounted securities, taxable income may result.     
                    Furthermore, each Portfolio expects to invest              
                    substantially all of its assets in California municipal    
                    securities. As a result, each Portfolio will be eligible   
                    to pay dividends to California residents that will be      
                    exempt from California personal income taxes.              
                    
                    Net long-term capital gains realized by a Portfolio from
                    the sale of securities will be distributed as taxable
                    capital gains distributions for federal income tax
                    purposes. Any short-term capital gains or any taxable
                    interest income will be distributed as a taxable ordinary
                    dividend distribution for federal income tax purposes. In
                    general, such taxable income distributions from a
                    Portfolio are expected to be negligible in comparison with
                    tax-exempt dividends. However, under unusual
                    circumstances, a Portfolio may invest in securities other
                    than California municipal obligations. In such cases, a
                    portion of the Portfolio's income may be subject to
                    California income taxes, federal income taxes, or both.

                    At present, none of the Portfolios invests in AMT bonds.
                    However, were a Portfolio to invest in such bonds, all or
                    a portion of the Portfolio's dividends, while exempt from
                    the regular federal income tax, would be a tax preference
                    item for purposes of the federal alternative minimum tax.

                    income you received.

                    Capital gains distributions from a Portfolio and any
                    capital gains or losses realized from the sale or exchange
                    of shares will generally be subject to state and local
                    taxes.


                    The Fund is required to withhold 31% of any 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 indicating your proper Social
                    Security or Employer Identification Number on your Account
                    Registration Form and by certifying that you are not
                    subject to backup withholding.

                    Up to 85% of an individual's Social Security benefits may
                    be subject to federal income tax. Along with other
                    factors, total tax-exempt income, including any tax-exempt
                    dividend income from Portfolios of the Fund, is used to
                    calculate the taxable portion of Social Security benefits.

                    The Fund is organized as a Pennsylvania business trust
                    and, in the opinion of counsel, is not liable for any
                    income or franchise tax in the Commonwealth of
                    Pennsylvania. The Fund will be subject to Pennsylvania
                    county personal property tax in the county which is the
                    site of its principal office.

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

THE SHARE PRICE 
OF EACH PORTFOLIO   The share price or "net asset value" per share of each
                    Portfolio is determined 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.


                    California Money Market Portfolio. For the purpose of
                    calculating the California Money Market Portfolio's net
                    asset value per share, securities are valued by the
                    "amortized cost" method of valuation, which does not take
                    into account unrealized gains or losses. This involves
                    valuing an instrument at its cost and thereafter assuming
                    a constant amortization to maturity of any discount or
                    premium, regardless of the impact of fluctuating interest
                    rates on the market value of the instrument. While this
                    method provides certainty in valuation, it may result in
                    periods during which value, as determined by amortized
                    cost, is higher or lower than the price the Portfolio
                    would receive if it sold the instrument.

                    The use of amortized cost and the maintenance of the
                    California Money Market Portfolio's per share net asset
                    value at $1.00 is based on its election to operate under
                    the provisions of Rule 2a-7 under the Investment Company
                    Act of 1940. As a condition of operating under that rule,
                    the California Money Market Portfolio must maintain a
                    dollar-weighted average portfolio maturity of 90 days or
                    less, purchase only instruments having remaining
                    maturities of 13 months or less, and invest only in
                    securities that are determined by the Trustees to present
                    minimal credit risks and that are of high quality as
                    determined by any major rating service, or in the case of
                    any instrument not so rated, considered by the Trustees to
                    be of comparable quality.



                                                                            25

                    The Trustees have established procedures designed to
                    stabilize the net asset value per share as computed for
                    the purposes of sales and redemptions at $1.00. These
                    procedures include periodic review, as the Trustees deem
                    appropriate and at such intervals as are reasonable in
                    light of current market conditions, of the relationship
                    between the amortized cost value per share and a net asset
                    value per share based upon available indications of market
                    value. In such a review, investments for which market
                    quotations are readily available are valued at the most
                    recent bid price or quoted yield equivalent for such
                    securities or for securities of comparable maturity,
                    quality and type as obtained from one or more of the major
                    market makers for the securities to be valued. Other
                    investments and assets are valued at fair value, as
                    determined in good faith by the Trustees.

                    In the event of a deviation of over 1/2 of 1% between a
                    Portfolio's net asset value based upon available market
                    quotations or market equivalents and $1.00 per share based
                    on amortized cost, the Trustees will promptly consider
                    what action, if any, should be taken. The Trustees will
                    also take such action as they deem appropriate to
                    eliminate or to reduce, to the extent reasonably
                    practicable, any material dilution or other unfair results
                    to investors or existing shareholders which might arise
                    from differences between the two. Such action may include
                    redeeming shares in kind, selling instruments prior to
                    maturity to realize capital gains or losses or to shorten
                    average maturity, withholding dividends, paying
                    distributions from capital or capital gains, or utilizing
                    a net asset value per share based upon available market
                    quotations.


                    California Insured Intermediate-Term and Insured Long-Term
                    Portfolios. The net asset value per share of the
                    California Insured Intermediate-Term and Insured Long-Term
                    Portfolios is determined as of the close of regular
                    trading on the New York Stock Exchange (generally 4:00
                    p.m. Eastern time) on each day that the Exchange is open
                    for business. When approved by the Board of Trustees,
                    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 pricing
                    services are generally determined without regard to bid or
                    last sale prices. Because of the large number of
                    outstanding municipal bonds, the majority of issues do not
                    trade each day; therefore, last sale prices are not
                    normally available. In valuing such securities, the
                    pricing services generally take into account institutional
                    size trading in similar groups of securities and any
                    developments related to specific securities.) The methods
                    used by the pricing service and the valuations so
                    established are reviewed by the Officers of the Fund under
                    the general supervision of the Trustees. There are a
                    number of pricing services available and the Trustees, on
                    the basis of ongoing evaluation of these services, may use
                    other pricing services or discontinue the use of any
                    pricing service.


                    Securities not priced in this manner are priced at the
                    most recent quoted bid price provided by investment
                    dealers. Short-term instruments maturing within 60 days

GENERAL 
INFORMATION         Vanguard California Tax-Free Fund is a Pennsylvania
                    business trust. The Declaration of Trust permits the
                    Trustees to issue an unlimited number of shares of
                    beneficial interest, without par value, from an unlimited
                    number of classes of shares. Currently the Fund is
                    offering three classes of shares (known as "Portfolios").

                    Shares of each Portfolio when issued are fully paid and
                    non-assessable; participate equally in dividends,
                    distributions and net assets; are entitled to one vote per
                    share; have pro rata liquidation rights; and do not have
                    pre-emptive rights. Also, shares of the Fund have
                    non-cumulative voting rights, meaning that the holders of
                    more than 50% of the shares voting for the election of the
                    Trustees can elect all of the Trustees 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 on the
                    removal of a Trustee or Trustees of the Fund if requested
                    in writing by the holders of not less than 10% of the
                    outstanding shares of the Fund.

                    All securities and cash are held by CoreStates Bank, N.A.,
                    Philadelphia, PA. The Vanguard Group, Inc., Valley Forge,
                    PA, serves as the Fund's Transfer and Dividend Disbursing
                    Agent. Price Waterhouse LLP serves as independent
                    accountants for the Fund and audits its financial
                    statements annually. The Fund is not involved in any
                    litigation.

OPENING AN 
ACCOUNT AND 
PURCHASING 
SHARES              To open a new account, either by mail or by wire, simply
                    complete and return an Account Registration Form and any
                    required legal documentation. Please indicate 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 in any
                    Portfolio ($1,000 for Uniform Gifts/Transfers to Minors
                    Act accounts). In addition, you must be a California
                    resident to invest in the Fund. If you need assistance
                    with the Account Registration Form or have any questions,
                    please call our Investor Information Department at
                    1-800-662-7447. Note: For other types of account
                    registrations (e.g. corporations, associations, other
                    organizations, trusts or powers of attorney), please call
                    us to determine which additional forms you may need. 

                    Each Portfolio's shares generally 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). 

Purchase 
Restrictions     1) 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.

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

Additional
Investments         Subsequent investments may be made by mail ($100 minimum
                    per Portfolio), wire ($1,000 minimum per Portfolio),
                    exchange from another Vanguard Fund account ($100 minimum
                    per Portfolio), or Vanguard Fund Express.

TAX CAUTION        Under Federal tax laws, the Fund is required to distribute 
                   net capital gains and investment income to Fund            
Investors should   shareholders. These distributions are made to all           
ask about the      shareholders who own Fund shares as of the distribution's   
timing of capital  record date, regardless of how long the shares have been    
gains and          owned. Purchasing shares just prior to the record date      
dividend           could have a significant impact on your tax liability for   
distributions      the year. For example, if you purchase shares immediately   
before investing   prior to the record date of a sizable capital gain, you     
                   will be assessed taxes on the amount of the capital gain    
                   distribution later paid even though you owned the Fund      
                   shares for just a short period of time. (Taxes are due on   
                   the distributions even if the capital gain is reinvested in 
                   additional Fund shares.) While the total value of your      
                   investment will be the same after the capital gain          
                   distribution--the amount of the capital gain distribution   
                   will offset the drop in the net asset value of the          
                   shares--you should be aware of the tax implications the     
                   timing of your purchase may have.                           
 
                   Prospective investors should, therefore, inquire about
                   potential distributions before investing. 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."

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


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


                   For purchases by check for the Money Market Portfolio the
                   Fund is ordinarily credited with Federal Funds within one
                   business day. 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
                   following receipt of your check. If your purchase is
                   received after the close of the Exchange, your trade date
                   is the second 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 net asset value determined
                   on your trade date. 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.) For a
                   purchase of the Money Market Portfolio by Federal Funds
                   wire, you may qualify for a dividend on the date of
                   purchase if you have notified the Fund of your intention to
                   make the purchase by 10:45 a.m. (Eastern time) on the
                   business day of the wire.


                                                                            31

                   In order to prevent lengthy processing delays caused by the
                   clearing of foreign checks, Vanguard will only accept a
                   foreign check which has been drawn in U.S. dollars and has
                   been issued by a foreign bank with a U.S. correspondent
                   bank. The name of the U.S. correspondent bank must be
                   printed on the face of the foreign check.

                   Each Portfolio reserves the right to suspend the offering
                   of shares for a period of time. Each Portfolio also
                   reserves the right to reject any specific purchase request.

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

Selling By 
Writing A Check    You may withdraw funds from your account by writing a check
                   payable in the amount of $250 or more. When a check is
                   presented for payment to the Fund's agent, CoreStates Bank,
                   the Fund will redeem sufficient shares in your account at
                   the net asset value next determined 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 any check.
                      If you wish to reverse a stop payment order, you must do 
                      so in writing. 
                   4. Shares held in certificate form cannot be redeemed using
                      the checkwriting option. 
                   5. The Fund reserves the right to terminate or alter this
                      service at any time.

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


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


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

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

                   A request to change the bank associated with your wire
                   redemption option must be received in writing, signed by
                   each registered shareholder, and accompanied by a voided
                   check or preprinted deposit slips. A signature guarantee is
                   required if your bank registration is not identical to your
                   Vanguard Fund account registration.

Important 
Redemption
Information        Shares purchased by check or Fund Express may be redeemed
                   at any time. However, your redemption proceeds will not be
                   paid until payment for the purchase is collected, which may
                   take up to ten calendar days.
                   ------------------------------------------------------------
Delivery of 
Redemption 
Proceeds           Redemption requests received by telephone prior to the
                   close of the New York Stock Exchange (generally 4:00 p.m.
                   Eastern time) are processed on the day of receipt and the
                   redemption proceeds are normally sent on the following
                   business day.
                            
                   Redemption requests received by telephone after the close
                   of the Exchange are processed on the business day following
                   receipt and the proceeds are normally sent on the second
                   business day following receipt.


                   All unpaid dividends credited to your account up to the
                   date of redemption will be included in the redemption
                   check. Redemption proceeds must be sent to you within seven
                   days of receipt of your request in Good Order, except as
                   described above in "Important Redemption Information."


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

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


Vanguard's 
Average Cost 
Statement          If you make a redemption from a qualifying account,
                   Vanguard will send you an Average Cost Statement which
                   provides you with the tax basis of the shares you redeemed.
                   Please see "Statement and Reports" for additional
                   information.

Low Balance Fee 
and Minimum 
Account Balance 
Requirement        Due to the relatively high cost of maintaining smaller
                   accounts, the Fund will automatically deduct a $10 annual
                   fee from accounts with balances falling below $2,500
                   ($1,000 for Uniform Gifts/Transfers to Minors Act
                   accounts). This fee deduction will occur mid-year,
                   beginning in 1996. The fee generally will be waived for
                   investors whose aggregate Vanguard assets exceed $50,000.

                   In addition, the Fund reserves the right to liquidate any
                   non-retirement account that is below the minimum initial
                   investment amount of $3,000. If at any time your total
                   investment does not have a value of at least $3,000, you

            
34
<PAGE>



                   may be notified that your account is below the Fund's
                   minimum account balance requirement. You would then be
                   allowed 60 days to make an additional investment before the
                   account is liquidated. Proceeds would be promptly paid to
                   the registered shareholder.


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

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

                   o 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).

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

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

                                                                            35
<PAGE>

                   o The shares to be exchanged must be on deposit and not
                     held in certificate form.

                   o New accounts are not currently accepted in
                     Vanguard/Windsor Fund or Vanguard/PRIMECAP Fund.

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

                   o When opening a new account by exchange, the required 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 Fund's exchange privilege is only available in
                   California, the only state in which the Fund's shares are
                   registered for sale.
- ------------------------------------------------------------------------------
EXCHANGE 
PRIVILEGE 
LIMITATIONS        The Fund's exchange privilege is not intended to afford
                   shareholders a way to speculate on short-term movements in
                   the market. Accordingly, in order to prevent excessive use
                   of the exchange privilege that may potentially disrupt the
                   management of the Fund and increase transaction costs, the
                   Fund has established a policy of limiting excessive
                   exchange activity.

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

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


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

                   2. Payment Policy. The proceeds of any telephone redemption
                   made 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.

<PAGE>

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

                            INVESTMENT LIMITATIONS 

   The following limitations cannot be changed without the consent of the 
holders of a majority of the Fund's outstanding shares (as defined in the 
Investment Company Act of 1940 (the "1940 Act")), including a majority of the 
shares of each Portfolio. 

       1. Each Portfolio will limit the aggregate value of all holdings 
   (except U.S. Government and cash items. as defined under Subchapter M of 
   the Internal Revenue Code (the "Code"), each of which exceeds 5% of the 
   Portfolio's total assets, to an aggregate amount of 50% of such assets; 
       2. Each Portfolio will limit the aggregate value of holdings of a 
   single issuer (except U.S. government and cash items, as defined in the 
   Code) to a maximum of 25% of the Portfolio's total assets. For the 
   purposes of this limitation, identification of the issuer will be based on 
   a determination of the source of assets and revenues committed to meeting 
   interest and principal payments of each security; 
       3. Each Portfolio will not borrow money except for temporary or 
   emergency purposes and then only in an amount not exceeding 10% of the 
   value of the total assets of that Portfolio. The Portfolio will repay all 
   borrowing before making additional investments. Interest paid on such 
   borrowings will reduce income; 
       4. Each Portfolio will not pledge, mortgage or hypothecate its assets 
   to any extent greater than 10% of the value of the total assets of the 
   Portfolio; 
       5. Each Portfolio will not issue senior securities as defined in the 
   1940 Act; 
                                                                           B-1
<PAGE>


       6. Each Portfolio will not engage in the business of underwriting 
   securities issued by other persons, except to the extent that the 
   Portfolio may technically be deemed an underwriter under the Securities 
   Act of 1933, as amended, in disposing of portfolio securities; 

       7. Each Portfolio will not purchase or otherwise acquire any security, 
   if as a result, more than 15% (10% with respect to the Money Market 
   Portfolio) of its net assets would be invested in securities that are 
   illiquid (included in this limitation is the Fund's investment in The 
   Vanguard Group, Inc.); 

       8. Each Portfolio will not purchase or sell real estate, but this shall 
   not prevent investments in Municipal Bonds secured by real estate or 
   interests therein; 
       9. Each Portfolio will not make loans to other persons, except by the 
   purchase of bonds, debentures or similar obligations which are publicly 
   distributed and as provided under "Lending of Securities"; 
       10. Each Portfolio will not purchase on margin or sell short, except as 
   specified below in Investment Limitation No. 12; 
       11. Each Portfolio will not purchase or retain securities of an issuer 
   if those Trustees of the Fund, each of whom owns more than 1/2 of 1% of 
   such securities, together own more than 5% of the securities of such 
   issuer; 
       12. Each Portfolio will not purchase or sell commodities or commodities 
   contracts, except that the California Insured Intermediate-Term and 
   Long-Term Portfolios may invest in bond futures contracts, bond options 
   and options on bond futures contracts to the extent that not more than 5% 
   of a Portfolio's assets are required as deposit on futures contracts and 
   not more than 20% of the Portfolio's assets are invested in futures 
   contracts and/or options transactions at any time; 
       13. Each Portfolio will not invest its assets in securities of other 
   investment companies except as they may be part of a merger, 
   consolidation, reorganization or acquisition of assets or otherwise, to 
   the extent permitted by Section 12 of the 1940 Act; 

       14. Each Portfolio will not invest in securities other than municipal 
   bonds except that each Portfolio may make temporary investments in (a) 
   notes issued by or on behalf of municipal or corporate issuers, 
   obligations of the U.S. Government and its agencies, commercial paper, and 
   bank certificates of deposit; (b) investment companies investing in such 
   securities which have investment objectives consistent with those of the 
   Portfolio to the extent permitted by the 1940 Act; and (c) any such 
   securities or municipal bonds subject to repurchase agreements;

       15. Each Portfolio will not invest in put, call, straddle or spread 
   options (except as described above in investment limitation No. 12) or 
   interests in oil, gas or other mineral exploration or development 
   programs; 
       16. Each Portfolio will not purchase an industrial revenue bond if as a 
   result of such purchase (i) more than 5% of the Portfolio's total assets, 
   determined at market value at the time of the proposed investment, would 
   be invested in industrial revenue bonds where the payment of principal and 
   interest is the responsibility of a company with less than three (3) 
   years' operating history, or (ii) more than 20% of the Portfolio's total 
   assets, determined at market value at the time of the proposed investment, 
   would be invested in industrial development bonds. These restrictions do 
   not apply to municipal obligations where the payment of principal and 
   interest is the responsibility of a government or the political 
   subdivision of a government. 


   The above-mentioned investment limitations are considered at the time 
investment securities are purchased. Notwithstanding these limitations, each 
Portfolio may own all or any portion of the securities of, or make loans to, 
or contribute to the costs or other financial requirements of, any company 
which will be (1) wholly owned by the Fund and one or more other investment 

B-2

<PAGE>
companies and (2) primarily engaged in the business of providing, at cost,
management, administrative, distribution and/or related services to the Fund
and such other investment companies. Additionally, the Fund may invest in
when-issued securities without limitation. Please see the prospectus for a
description of securities.
   
                             INVESTMENT POLICIES
    
   Lending of Securities. Each Portfolio may lend its investment securities 
to qualified institutions who need to borrow securities in order to complete 
certain transactions, such as covering short sales, avoiding failures to 
deliver securities or completing arbitrage operations. By lending its 
investment securities, the Portfolio attempts to increase its income through 
the receipt of interest on the loan. Any gain or loss in the market price of 
the securities loaned that might occur during the term of the loan would be 
for the account of the Portfolio. The Portfolio may lend its investment 
securities to qualified brokers, dealers, banks or other financial 
institutions, so long as the terms and the structure of such loans are not 
inconsistent with the 1940 Act, or the Rules and Regulations or 
interpretations of the Securities and Exchange Commission (the "Commission") 
thereunder, which currently require that (a) the borrower pledge and maintain 
with the Portfolio collateral having a value at all times not less than 100% 
of the value of the securities loaned, (b) the borrower add to such 
collateral whenever the price of the securities loaned rises (i.e., the 
borrower "marks to the market" on a daily basis), (c) the loan be made 
subject to termination by the Portfolio at any time and (d) the Portfolio 
receive reasonable interest on the loan (which may include the Portfolio 
investing any cash collateral in interest bearing short- term investments), 
any distribution on the loaned securities and any increase in their market 
value. A Portfolio will not lend its investment securities, if as a result, 
the aggregate of such loans exceeds 10% of the value of its total assets. 
Loan arrangements made by the Portfolio will comply with all other applicable 
regulatory requirements, including the rules of the New York Stock Exchange, 
which rules presently require the borrower, after notice, to redeliver the 
securities within the normal settlement time of three business days. All 
relevant facts and circumstances, including the creditworthiness of the 
broker, dealer or institution, will be considered in making decisions with 
respect to the lending of securities, subject to review by the Fund's Board 
of Trustees. Income derived from lending of securities is not tax- exempt, 
and, thus, a Portfolio will limit such activity in accordance with its 
investment objective. 


FUTURES CONTRACTS AND OPTIONS 

   The Insured Intermediate-Term and Insured Long-Term Portfolios may enter 
into futures contracts, options, and options on futures contracts for several 
reasons: to maintain cash reserves while simulating full investment, to 
facilitate trading, to reduce transactions costs, or to seek higher 
investment returns when a futures contract is priced more attractively than 
the underlying municipal security or index. Futures contracts provide for the 
future sale by one party and purchase by another party of a specified amount 
of a specific security at a specified future time and at a specified price. 
Futures contracts which are standardized as to maturity date and underlying 
financial instrument are traded on national futures exchanges. Futures 
exchanges and trading are regulated under the Commodity Exchange Act by the 
Commodity Futures Trading Commission ("CFTC"), a U.S. Government Agency. 

   Although futures contracts by their terms call for actual delivery or 
acceptance of the underlying securities, in most cases the contracts are 
closed out before the settlement date without the making or taking of 
delivery. Closing out an open futures position is done by taking an opposite 
position ("buying" a contract which has previously been "sold," or "selling" 
a contract previously purchased) in an identical contract to terminate the 
position. Brokerage commissions are incurred when a futures contract is 
bought or sold. 

   Futures traders are required to make a good faith margin deposit in cash 
or government securities with a broker or custodian to initiate and maintain 
open positions in futures contracts. A margin deposit is intended to assure 
completion of the contract (delivery or acceptance of the underlying 
security) if it is not terminated prior to the specified delivery date. 
Minimal initial margin requirements are established by the futures exchange 
and may be changed. Brokers may establish deposit requirements which are 
higher than the exchange minimums. Futures contracts are customarily 
purchased and sold at prices which may range upward from less than 5% of the 
value of the contract being traded. 

   After a futures contract position is opened, the value of the contract is 
marked to market daily. If the futures contract price changes, to the extent 

                                                                           B-3

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

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

   Regulations of the CFTC applicable to the Fund require that all of its 
futures transactions constitute bona fide hedging transactions. The Portfolio 
will only sell futures contracts to protect securities it owns against price 
declines or purchase contracts to protect against an increase in the price of 
securities it intends to purchase. As evidence of this hedging interest, the 
Portfolio expects that approximately 75% of its futures contract purchases 
will be "completed," that is, equivalent amounts of related securities will 
have been purchased or are being purchased by the Portfolio upon sale of open 
futures contracts. 

   Although techniques other than the sale and purchase of futures contracts 
could be used to control the Portfolio's exposure to market fluctuations, the 
use of futures contracts may be a more effective means of hedging this 
exposure. While the Portfolio will incur commission expenses in both opening 
and closing out futures positions, these costs are lower than transaction 
costs incurred in the purchase and sale of the underlying securities. 

RESTRICTIONS ON THE USE OF FUTURES CONTRACTS 

   A Portfolio will not enter into futures contract transactions to the 
extent that, immediately thereafter, the sum of its initial margin deposits 
on open contracts exceeds 5% of the market value of the Fund's total assets. 
In addition, a Portfolio will not enter into futures contracts to the extent 
that its outstanding obligations to purchase securities under these contracts 
would exceed 20% of the Portfolio's total assets. Assets committed to futures 
contracts or options will be held in a segregated account at the Fund's 
custodian bank. 

RISK FACTORS IN FUTURES TRANSACTIONS 

   Positions in futures contracts may be closed out only on an Exchange which 
provides a secondary market for such futures. However, there can be no 
assurance that a liquid secondary market will exist for any particular 
futures contract at any specific time. Thus, it may not be possible to close 
a futures position. In the event of adverse price movements, a Portfolio 
would continue to be required to make daily cash payments to maintain its 
required margin. In such situations, if the Portfolio has insufficient cash, 
it may have to sell portfolio securities to meet daily margin requirements at 
a time when it may be disadvantageous to do so. In addition, the Portfolios 
may be required to make delivery of the instruments underlying futures 
contracts it holds. The inability to close options and futures positions also 
could have an adverse impact on the ability to effectively hedge it. 

   The Portfolios will minimize the risk that they will be unable to close 
out a futures contract by only entering into futures which are traded on 
national futures exchanges and for which there appears to be a liquid 
secondary market. The principal interest rate futures exchanges in the United 
States are the Board of Trade of the City of Chicago and the Chicago 
Mercantile Exchange. 

   The risk of loss in trading futures contracts in some strategies can be 
substantial, due both to the low margin deposits required, and the extremely 
high degree of leverage involved in futures pricing. As a result, a 
relatively small price movement in a futures contract may result in immediate 
and substantial loss (as well as gain) to the investor. For example, if at 
the time of purchase, 10% of the value of the futures contract is deposited 
as margin, a subsequent 10% decrease in the value of the futures contract 
would result in a total loss of the margin deposit, before any deduction for 

B-4

<PAGE>

the transaction costs, if the account were then closed out. A 15% decrease
would result in a loss equal to 150% of the original margin deposit if the
contract were closed out. Thus, a purchase or sale of a futures contract may
result in losses in excess of the amount invested in the contract. However,
because the futures strategies of the Portfolio are engaged in only for
hedging purposes, the Adviser does not believe that the Portfolio is subject
to the risks of loss frequently associated with futures transactions. The
Portfolio would presumably have sustained comparable losses if, instead of the
futures contract, it had invested in the underlying financial instrument and
sold it after the decline.

   Utilization of futures transactions by the Portfolios does involve the 
risk of imperfect or no correlation where the securities underlying futures 
contracts have different maturities or other characteristics than the 
portfolio securities being hedged. It is also possible that the Portfolios 
could both lose money on futures contracts and also experience a decline in 
value of its portfolio securities. There is also the risk of loss by a 
Portfolio of margin deposits in the event of bankruptcy of a broker with whom 
the Portfolio has an open position in a futures contract or related option. 

   Most futures exchanges limit the amount of fluctuation permitted in 
futures contract prices during a single trading day. The daily limit 
establishes the maximum amount that the price of a futures contract may vary 
either up or down from the previous day's settlement price at the end of a 
trading session. Once the daily limit has been reached in a particular type 
of contract, no trades may be made on that day at a price beyond that limit. 
The daily limit governs only price movement during a particular trading day 
and therefore does not limit potential losses, because the limit may prevent 
the liquidation of unfavorable positions. Futures contract prices have 
occasionally moved to the daily limit for several consecutive trading days 
with little or no trading, thereby preventing prompt liquidation of future 
positions and subjecting some futures traders to substantial losses. 

FEDERAL TAX TREATMENT OF FUTURES CONTRACTS 

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

   In order for each Portfolio to continue to qualify for Federal income tax 
treatment as a regulated investment company, at least 90% of its gross income 
for a taxable year must be derived from qualifying income; i.e., dividends, 
interest, income derived from loans of securities, gains from the sale of 
securities or of foreign currencies or other income derived with respect to 
the Portfolio's business of investing in securities. In addition, gains 
realized on the sale or other disposition of securities held for less than 
three months must be limited to less than 30% of the Portfolio's annual gross 
income. It is anticipated that any net gain realized from the closing out of 
futures contracts will be considered gain from the sale of securities and 
therefore be qualifying income for purposes of the 90% requirement. In order 
to avoid realizing excessive gains on securities held less than three months, 
the Portfolios may be required to defer the closing out of futures contracts 
beyond the time when it would otherwise be advantageous to do so. It is 
anticipated that unrealized gains on futures contracts, which have been open 
for less than three months as of the end of each Portfolio's fiscal year and 
which are recognized for tax purposes, will not be considered gains on sales 
of securities held less than three months for the purpose of the 30% test. 

   The Portfolios will distribute to shareholders annually any net capital 
gains which have been recognized for federal income tax purposes (including 
unrealized gains at each end of the Portfolio's fiscal year) on futures 
transactions. Such distributions will be combined with distributions of 
capital gains realized on the Portfolio's other investments and shareholders 
will be advised on the nature of the transactions. 

                                                                           B-5

                                 RISK FACTORS 
                      VANGUARD CALIFORNIA TAX-FREE FUND 

   The Vanguard California Tax-Free Fund invests primarily in the obligations 
of California state government and various local governments, including 
counties, cities, special districts, agencies and authorities. In general, 
the credit quality and credit risk of any issuer's debt depend on the state 
and local economy, the health of the issuer's finances, the amount of the 
issuer's debt, the quality of management, and the strength of legal 
provisions in debt documents that protect debt holders. Credit risk is 
usually lower wherever the economy is strong, growing and diversified; 
financial operations are sound; and the debt burden is reasonable. 

   The credit risk associated with direct obligations of the State of 
California and State agencies, including general obligation and revenue 
bonds, lease debt, and notes, is now average. For most of the last two 
decades, the State's general obligation bonds had enjoyed the highest rating 
by either Moody's Investors Service or Standard & Poor's. California's high 
credit quality reflected the growth of its strong and diversified economy, a 
low debt position, wealth levels higher than the national average, and a 
generally sound and stable financial position. However, California's credit 
quality has declined since the onset of the national recession in 1990. 

   California's economy, largest among the states, is also one of the largest 
in the world. The State's population, nearly 30 million in 1990, has doubled 
since 1960 and constitutes about 12% of the U.S. total. Rapid growth is 
continuing, with rates more than twice that of the national average during 
the 1980s. Personal income growth lagged U.S. growth in the 1980s, but per 
capita income was still 10% above the national average in 1990. A growing, 
young population, a strong higher education system, and excellent ports 
continue to bolster California's economic prospects. Employment and income 
are not concentrated in any one sector. In fact, California's economy closely 
mirrors that of the U.S. One caveat to this observation concerns the defense 
industry. For many years, California has led the Nation in receipt of total 
direct U.S. military expenditures. However, as the State's economy expanded, 
the concentration in defense has lessened. Nonetheless, as U.S. policy has 
resulted in lower defense spending, parts of California, especially the Los 
Angeles Region, have been adversely affected, and these trends might 
continue. 

   The State economy and State financial operations are exposed to the risk 
of cyclical national recessions. In recession, credit quality can drop if 
debt issuers do not maintain a balance between revenues and expenditures. 
This occurred in the early 1980s when Moody's and Standard & Poor's 
downgraded the State. Subsequently, State finances were restored to sound 
levels, and credit ratings were upgraded. California was especially hard hit 
by the recent national recession and experienced three credit-rating 
downgrades by each of the two major rating agencies. The effects of recession 
were not strongly felt in California until 1991 and the state has recently 
begun to emerge from the depths of recession. Led by declines in 
defense-related activities and construction (especially commercial real 
estate), the State lost over 800,000 jobs between 1990-1993, or about 6% of 
non-agricultural employment. The recession resulted in a failure by State 
government to realize revenue and spending targets. The State budget was 
chronically imbalanced in 1991 and 1992. State aid was reduced, spreading 
fiscal stress to local governments, including schools. Severe fiscal stress 
continues in State government and many local governments, and additional 
credit-rating downgrades are possible. 

   Despite the overall strength of California credit quality, there are a 
number of additional risks. The adoption of revenue and expenditure 
limitations (articles XIIIA and XIIIB of the California Constitution) by 
voters in the late 1970s placed many local governments under a degree of 
fiscal stress which continues. Court decisions and the adoption of subsequent 
propositions softened many of the effects of these limitations. However, it 
should be noted that California voters have demonstrated a willingness to 
utilize the statutory initiative process to curtail the financial operations 
of state and local government, as well as to increase public debt. This 
willingness is a continuing risk to debt holders. 

   Another risk resulting from Proposition 13 concerns the security 
provisions for debt repayment. Since 1978, general obligation debt issuance 
has required voter approval by a two-thirds majority. As a result, most 
tax-backed debt now issued by California local governments is not general 
obligation debt, does not have "full faith and credit" backing, and has 
higher credit risk and more limited bondholder rights. 

B-6

<PAGE>

   Some risks in California apply more to local issuers than to state 
government. In areas of very rapid population growth, the costs of building 
public infrastructure are very high, large amounts of municipal bonds are 
being sold, and debt burden is increasing. In some parts of southern 
California, there is also a fear that population growth may possibly limit 
future economic growth due to transportation and air pollution problems. 

   Finally, California is subject to unique natural hazard risks. Earthquakes 
and wildfires can cause localized economic harm which could limit the ability 
of governments to repay debt. Drought is also a concern insofar as it affects 
agricultural production, power generation, and the supply of drinking water. 
Drought not only places stress on the economy generally; it can limit the 
ability of certain public utilities to repay debt. 
   
    
                            YIELD AND TOTAL RETURN 

   The yield of the California Insured Long-Term Portfolio and the California 
Insured Intermediate-Term Portfolio for the 30-day period ended November 30, 
1995 was 5.15% and 4.61%, respectively. 

   The average annual total return of the California Insured Long-Term 
Portfolio for the one- and five- year periods ended November 30, 1995, and 
the period since (inception April 7, 1986) to November 30, 1995, was +20.11%, 
+8.70 and +8.11%, respectively. The total return of the California Insured 
Intermediate-Term Portfolio for the one-year period and the period since 
inception (March 4, 1994) to November 30, 1995 was +13.88% and +7.63%, 
respectively. The average annual total return of the California Money Market 
Portfolio for the one-year and five-year periods ended November 30, 1995, and 
the period from inception (June 1, 1987) to November 30, 1995, was +3.69%, 
+3.22% and +4.14%, respectively. Total return is computed by finding the 
average compounded rates of return over the one-year period set forth above 
that would equate an initial amount invested at the beginning of the period 
to the ending redeemable value of the investment. 


                             CALCULATION OF YIELD 

   The current yield of the California Money Market Portfolio is calculated 
daily on a base period return of a hypothetical account having a beginning 
balance of one share for a particular period of time (generally 7 days). The 
return is determined by dividing the net change (exclusive of any capital 
changes) in such account by its average net asset value for the period, and 
then multiplying it by 365/7 to get the annualized current yield. The 
calculation of net change reflects the value of additional shares purchased 
with the dividends by the Portfolio, including dividends on both the original 
share and on such additional shares. An effective yield, which reflects the 
effects of compounding and represents an annualization of the current yield 
with all dividends reinvested, may also be calculated for the Portfolio by 
adding 1 to the net change, raising the sum to the 365/7 power, and 
subtracting 1 from the result. 


   Set forth below is an example, for purposes of illustration only, of the 
current and effective yield calculations for the California Money Market 
Portfolio for the 7-day base period ended November 30, 1995. 

                                                                           B-7

   The net asset value of the California Money Market Portfolio is $1.00 and 
it is not expected to fluctuate. The Money Market Portfolio seeks to 
maintain, but does not guarantee, a constant net asset value of $1.00 per 
share. Although the Money Market Portfolio invests in high-quality 
instruments, the shares of the Portfolio are not insured or guaranteed by the 
U.S. Government. The yield of the Portfolio will fluctuate. The annualization 
of a week's dividend is not a representation by the Portfolio as to what an 
investment in the Portfolio will actually yield in the future. Actual yields 
will depend on such variables as investment quality, average maturity, the 
type of instruments the Portfolio invests in, changes in interest rates on 
instruments, changes in the expenses of the Fund and other factors. Yields 
are one basis investors may use to analyze the Portfolios of the Fund, and 
other investment vehicles, however, yields of other investment vehicles may 
not be comparable because of the factors set forth in the preceding sentence, 
differences in the time periods compared, and differences in the methods used 
in valuing portfolio instruments, computing net asset value and calculating 
yield.

                            INVESTMENT MANAGEMENT 

   The Fund receives all investment advisory services on an "internalized," 
at-cost basis from an experienced investment management staff employed 
directly by The Vanguard Group, Inc. ("Vanguard"), a subsidiary jointly owned 
by the Fund and the other Funds in The Vanguard Group of Investment 
Companies. The investment management staff is supervised by the senior 
officers of the Fund. 

   The investment management staff is responsible for: maintaining the 
specified standards; making changes in specific issues in light of changes in 
the fundamental basis for purchasing such securities; and adjusting the Fund 
to meet cash inflow (or outflow), which reflects net purchases and exchanges 
of shares by investors (or net redemptions of shares) and reinvestment of the 
Fund's income. 

   A change in securities held by the Fund is known as "portfolio turnover" 
and may involve the payment of the Fund of dealer mark-ups, underwriting 
commissions and other transaction costs on the sales of securities as well as 
on the reinvestment of the proceeds in other securities. The annual portfolio 
turnover rate for each of the Fund's portfolios is set forth under the 
heading "Financial Highlights" in the California Tax-Free Fund prospectus. 
The portfolio turnover rate is not a limiting factor when management deems it 
desirable to sell or purchase securities. It is impossible to predict whether 
or not the portfolio turnover rate in future years will vary significantly 
from the rates in recent years. 


   During the fiscal years ended November 30, 1993, 1994 and 1995, the Fund 
did not pay any brokerage commissions. 


                              PURCHASE OF SHARES 


   The Fund reserves the right in its sole discretion (i) to suspend the 
offering of its shares, (ii) to reject purchase orders when in the judgment 
of management such rejection is in the best interest of the Fund, and (iii) 
to reduce or waive the minimum investment for or any other restrictions on 
initial and subsequent investments under circumstances where certain 
economies can be achieved in sales of the Fund's shares. 


   Stock Certificates. Your purchase will be made in full and fractional 
shares of the Fund calculated to three decimal places. Shares are normally 
held on deposit for shareholders by the Fund, which will send to shareholders 
a statement of shares owned at the time of each transaction. This saves the 
shareholders the trouble of safekeeping the certificates and saves the Fund 
the cost of issuing certificates. Share certificates for the California 
Insured Intermediate-Term and Insured Long-Term Portfolios are, available 
upon written request at no additional cost to shareholders. No certificates 
will be issued for fractional shares of these Portfolios, or any shares of 
the Money Market Portfolio. 

                             REDEMPTION OF SHARES 

   The Fund may suspend redemption privileges or postpone the date of payment 
(i) during any period that the New York Stock Exchange is closed, or trading 
on the Exchange is restricted as determined by the Securities and Exchange 
Commission (the "Commission"), (ii) during any period when an emergency exists

B-10
<PAGE>

as defined by the rules of the Commission as a result of which it is not
reasonably practicable for the Fund to dispose of securities owned by it, or
fairly to determine the value of its assets, and (iii) for such other periods
as the Commission may permit.

   If the Board of Trustees determines that it would be detrimental to the 
best interests of the remaining shareholders of the Fund to make payment 
wholly or partly in cash, the Fund may pay the redemption price in whole or 
in part by a distribution in kind of securities held by the Fund in lieu of 
cash in conformity with applicable rules of the Commission. Investors may 
incur brokerage charges on the sale of such securities so received in payment 
of redemptions. 

   No charge is made by the Fund for redemptions except for wire redemptions 
of under $5000 which may be charged a maximum fee of $5.00. Any redemption 
may be more or less than the shareholder's cost depending on the market value 
of the securities held by the Fund. 


   Signature Guarantees. To protect your account, the Fund and Vanguard from 
fraud, signature guarantees are required for certain redemptions. Signature 
guarantees enable the Fund to verify the identity of the person who has who 
has authorized a redemption from your account. Signature guarantees are 
required in connection with: (1) all redemptions, regardless of the amount 
involved, when the proceeds are to be paid to someone other than the 
registered owners; and (2) share transfer requests. 


   A signature guarantee may be obtained from banks, brokers and any other 
guarantor institution that Vanguard deems acceptable. Notaries public are not 
acceptable guarantors. 

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

                             VALUATION OF SHARES 

   The valuation of shares of the California Insured Intermediate-Term and 
Insured Long-Term Portfolios is described in detail in the Prospectus. 


   California Money Market Portfolio. The net asset value per share of the 
California Money Market Portfolio is determined on each day that the New York 
Stock Exchange is open. 


   It is the policy of the California Money Market Portfolio to attempt to 
maintain a net asset value of $1.00 per share for purposes of sales and 
redemptions. The Money Market Portfolio seeks to maintain, but does not 
guarantee, a constant net asset value of $1.00 per share. Although the Money 
Market Portfolio invests in high-quality instruments, the shares of the 
Portfolio are not insured or guaranteed by the U.S. Government. The 
instruments held by the California Money Market Portfolio are valued on the 
basis of amortized cost which does not take into account unrealized capital 
gains or losses. This involves valuing an instrument at-cost and thereafter 
assuming a constant amortization to maturity of any discount or premium, 
regardless of the impact of fluctuating interest rates on the market value of 
the instrument. While this method provides certainty in valuation, it may 
result in periods during which value, as determined by amortized cost, is 
higher or lower than the price the Portfolio would receive if it sold the 
instrument. During periods of declining interest rates, the daily yield on 
shares of the Portfolio computed as described above may tend to be higher 
than a like computation made by a fund with identical investments utilizing a 
method of valuation based upon market prices and estimates of market prices 
for all of its portfolio instruments. Thus, if the use of amortized cost by 
the Portfolio resulted in a lower aggregate portfolio value on a particular 
day, a prospective investor in the Portfolio would be able to obtain a 
somewhat higher yield than would result from investment in a fund utilizing 
solely market values, and existing investors in the Portfolio would receive 
less investment income. The converse would apply in a period of rising 
interest rates. 

   The valuation of the California Money Market Portfolio's instruments based 
upon their amortized cost and the commitment to maintain the Portfolio's per 
share net asset value of $1.00 is based on the conditions set forth in Rule 
2a-7 under the Investment Company Act of 1940. The Portfolio will maintain
    
                                                                      B-11
<PAGE>

a dollar-weighted average portfolio maturity of 90 days or less, will purchase
instruments having remaining maturities of thirteen months or less only, and
will invest only in securities determined by the Board of Trustees to be of
high quality with minimal credit risks.

   It is a fundamental objective of management to maintain the Portfolio's 
price per share as computed for the purpose of sales and redemptions at 
$1.00. The Trustees have established procedures designed to achieve this 
objective. Such procedures will include a review of the Portfolio's holdings 
by the Trustees, at such intervals as they may deem appropriate, to determine 
whether the Portfolio's net asset value calculated by using available market 
quotations deviates from $1.00 per share based on amortized cost. The extent 
of any deviation will be examined by the Trustees. If such deviation exceeds 
1/2 of 1%, the Trustees will promptly consider what action, if any, will be 
initiated. In the event the Trustees determine that a deviation exists which 
may result in material dilution or other unfair results to investors or 
existing shareholders, they have agreed to take such corrective action as 
they regard as necessary and appropriate, including the sale of portfolio 
instruments prior to maturity to realize capital gains or losses or to 
shorten average portfolio maturity; withholding dividends; making a special 
capital distribution; redemptions of shares in kind; or establishing a net 
asset value per share by using available market quotations.

THE VANGUARD GROUP 

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

   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 Trustees (Directors) of each 
Fund. In addition, each Fund bears its own direct expenses such as legal, 
auditing and custodian fees. In order to generate additional revenues for 
Vanguard and thereby reduce the Fund's expenses, Vanguard also provides 
certain administrative services to other organizations. 

   The Fund's Officers are also Officers and employees of Vanguard. No 
Officer or employee owns, or is permitted to own, any securities of any 
external adviser for the Funds. 

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


   The Vanguard Group, Inc. ("Vanguard") was established and operates under a 
Funds' Service Agreement which was approved by the shareholders of each of 
the Funds. The amounts which each of the Funds has invested are adjusted from 
time to time in order to maintain the proportionate relationship between each 
Fund's relative net assets and its contribution to Vanguard's capital. At 
November 30, 1995 Vanguard California Tax-Free Fund had contributed capital 
of $285,000 to Vanguard representing 1.4% of Vanguard's capitalization. The 
Fund's Service Agreement provides as follows: (a) each Vanguard Fund may 
invest up to 0.40% of its current net assets in Vanguard and (b) there is no 
restriction or the maximum cash investment that the Vanguard Funds may make 
in Vanguard. 

   Management. Corporate management and administrative services include: (1) 
executive staff; (2) accounting and financial; (3) legal and regulatory; (4) 
shareholder account maintenance; (5) monitoring and control of custodian 
relationships; (6) shareholder reporting; and (7) review and evaluation of 
advisory and other services provided to the Funds by third parties. During 
the fiscal year ended November 30, 1995, the Funds' share of Vanguard's 
actual net costs of operations relating to management and administrative 
services (including transfer agency) totaled approximately $3,387,000. 


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

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

   One half of the distribution expenses of a marketing and promotional 
nature is allocated among the Funds based upon their relative net assets. The 
remaining one half of these expenses is allocated among the Funds based upon 
each Fund's sales for the preceding 24 months relative to the total sales of 
the Funds as a Group, provided, however, that no Fund's aggregate quarterly 

                                                                          B-13
<PAGE>



rate of contribution for distribution expenses of a marketing and promotional
nature shall exceed 125% of the average distribution expense rate for the
Group, and that no Fund shall incur annual distribution expenses in excess of
20/100 of 1% of its average month-end net assets. During the year ended
November 30, 1995 the Fund paid approximately $534,000 of the Group's
distribution and marketing expenses.

   Investment Advisory Services. Vanguard also provides investment advisory 
services to the Fund, Vanguard Municipal Bond Fund, Vanguard Money Market 
Reserves, Vanguard Admiral Funds; the several Portfolios of Vanguard Fixed 
Income Securities Fund; Vanguard Institutional Index Fund; Vanguard Bond 
Index Fund; the Vanguard Florida Insured Tax-Free Fund; Vanguard New Jersey 
Tax-Free Fund; Vanguard New York Insured Tax-Free Fund; Vanguard Ohio 
Tax-Free Fund; Vanguard Pennsylvania Tax-Free Fund; Vanguard Tax-Managed 
Fund; the Aggressive Growth Portfolio of Vanguard Horizon Fund; Vanguard 
Balanced Index Fund; Vanguard Index Trust; Vanguard International Equity 
Index Fund; secured Portfolio of Vanguard Variable Insurance Fund; a portion 
of Vanguard/Windsor II, a portion of Vanguard/Morgen Growth Fund as well as 
several indexed separate accounts. These services are provided on an at-cost 
basis from a money management staff employed directly by Vanguard. The 
compensation and other expenses of this staff are paid by the Funds utilizing 
these services. During the years ended November 30, 1993, 1994 and 1995, the 
Fund paid approximately $174,000, $238,000 and $286,000 respectively, of 
Vanguard's investment advisory expenses. 
   
   Remuneration of Trustees and Officers. The Fund pays each Trustee, who is 
not also an Officer, an annual fee plus travel and other expenses incurred in 
attending Board meetings. During the year ended November 30, 1995 the Fund 
paid $8,000 in Trustees' expenses. The Fund's Officers and employees are paid 
by Vanguard which, in turn, is reimbursed by the Fund, and each other Fund in 
the Group, for its proportionate share of Officers' and employees' salaries 
and retirement benefits. During the year ended November 30, 1995 the Fund's 
proportionate share of remuneration paid to all Officers of the Fund, as a 
group, was approximately $74,627. 

   Trustees who are not Officers are paid an annual fee based on the number 
of years of service on the Board upon retirement. The fee is equal to $1,000 
for each year of service (up to fifteen years) and each investment company 
member of the Vanguard Group contributes a proportionate amount to this fee 
based on its relative net assets. Under its Retirement Plan, Vanguard 
contributes annually an amount equal to 10% of each eligible officer's annual 
compensation plus 5.7% of that part of an eligible officer's compensation 
during the year, if any, that exceeds the Social Security Taxable Wage Base 
then in effect. Under its Thrift Plan, all eligible Officers are permitted to 
make pre-tax contributions in an amount up to 4% of total compensation, 
subject to federal tax limitations, which are matched by Vanguard on a 100% 
basis. The Fund's proportionate share of retirement contributions made by 
Vanguard under its retirement and thrift plans on behalf of all Officers of 
the Fund, as a group, during the 1995 fiscal year was approximately $2,100.
    

   The following table provides detailed information with respect to the 
amounts paid or accrued for the Trustees for the fiscal year ended November 
30, 1995.

                   DESCRIPTION OF SHARES AND VOTING RIGHTS 

   The Fund was organized as a Pennsylvania Trust on October 16, 1985. 

   The Declaration of Trust, as amended and restated on January 15, 1986, 
permits the Trustees to issue an unlimited number of shares of beneficial 
interest, without par value, from an unlimited number of separate classes 
("Portfolios") of shares. Currently, the Fund is offering shares of three 
Portfolios. 

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

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

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

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

                                                                          B-15
<PAGE>

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

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

         APPENDIX A-DESCRIPTION OF MUNICIPAL BONDS AND THEIR RATINGS 

   Municipal Bonds--General. Municipal Bonds generally include debt 
obligations issued by states and their political subdivisions, and duly 
constituted authorities and corporations, to obtain funds to construct, 
repair or improve various public facilities such as airports, bridges, 
highways, hospitals, housing, schools, streets and water and sewer works. 
Municipal Bonds may also be issued to refinance outstanding obligations as 
well as to obtain funds for general operating expenses and for loan to other 
public institutions and facilities. 


   The two principal classifications of Municipal Bonds are "general 
obligation" and "revenue" or "special tax" bonds. General obligation bonds 
are secured by the issuer's pledge of its full faith, credit and taxing power 
for the payment of principal and interest. Revenue or special tax bonds are 
payable only from the revenues derived from a particular facility or class of 
facilities or, in some cases, from the proceeds of a special excise or other 
tax, but not from general tax revenues. The Fund may also invest in 
tax-exempt industrial development bonds, short-term municipal obligations 
(rated SP-1+ of SP-1 by Standard & Poor's Corp. or MIG. by Moody's Investors 
Service), demand notes and tax-exempt commercial papers (rated A-1 by 
Standard & Poor's Corp. or P-1 by Moody's Investors Service). 


   Industrial revenue bonds in most cases are revenue bonds and generally do 
not have the pledge of the credit of the issuer. The payment of the principal 
and interest on such industrial revenue bonds is dependent solely on the 
ability of the user of the facilities financed by the bonds to meet its 
financial obligations and the pledge, if any, of real and personal property 
so financed as security for such payment. Short-term municipal obligations 
issued by states, cities, municipalities or municipal agencies, include Tax 
Anticipation Notes, Revenue Anticipation Notes, Bond Anticipation Notes, 
Construction Loan Notes and Short-Term Discount Notes. 

   Note obligations with demand or put options may have a stated maturity in 
excess of one year, but permit any holder to demand payment of principal plus 
accrued interest upon a specified number of days' notice. Frequently, such 
obligations are secured by letters of credit or other credit support 
arrangements provided by banks. The issuer of such notes normally has a 

B-16
<PAGE>

corresponding right, after a given period, to repay in its discretion the
outstanding principal of the note plus accrued interest upon a specific number
of days' notice to the bondholders. The interest rate on a demand note may be
based upon a known lending rate, such as a bank's prime rate, and be adjusted
when such rate changes, or the interest rate on a demand note may be a market
rate that is adjusted at specified intervals. The demand notes in which the
Fund will invest are payable on not more than one year's notice. Each note
purchased by the Fund will meet the quality criteria set out above for the
Fund.

   The yields of Municipal Bonds depend on, among other things, general money 
market conditions, conditions in the Municipal Bond market, the size of a 
particular offering, the maturity of the obligation, and the rating of the 
issue. The ratings of Moody's Investors Service, Inc. and Standard & Poor's 
Corporation represent their opinions of the quality of the Municipal Bonds 
rated by them. It should be emphasized that such ratings are general and are 
not absolute standards of quality. Consequently, Municipal Bonds with the 
same maturity, coupon and rating may have different yields, while Municipal 
Bonds of the same maturity and coupon, but with different ratings may have 
the same yield. It will be the responsibility of the investment management 
staff to appraise independently the fundamental quality of the bonds held by 
the Fund. 

   Municipal Bonds are sometimes purchased on a "when-issued" basis meaning 
the Fund has committed to purchasing certain specified securities at an 
agreed upon price when they are issued. The period between commitment date 
and issuance date can be a month or more. It is possible that the securities 
will never be issued and the commitment canceled. 

   From time to time proposals have been introduced before Congress to 
restrict or eliminate the Federal income tax exemption for interest on 
Municipal Bonds. Similar proposals may be introduced in the future. If any 
such proposal were enacted, it might restrict or eliminate the ability of the 
Fund to achieve its investment objective. In that event, the Fund's Trustees 
and officers would reevaluate its investment objective and policies and 
consider recommending to its shareholders changes in such objective and 
policies. 

   Similarly, from time to time proposals have been introduced before State 
and local legislatures to restrict or eliminate the State and local income 
tax exemption for interest on Municipal Bonds. Similar proposals may be 
introduced in the future. If any such proposal were enacted, it might 
restrict or eliminate the ability of each Portfolio to achieve its respective 
investment objective. In that event, the Fund's trustees and officers would 
reevaluate its investment objective and policies and consider recommending to 
its shareholders changes in such objective and policies. (For more 
information please refer to "Risk Factors" on page 6.) 

   Ratings. Excerpts from Moody's Investors Service, Inc.'s Municipal Bond 
ratings: Aaa--judged to be of the "best quality" and are referred to as "gilt 
edge"; interest payments are protected by a large or by an exceptionally 
stable margin and principal is secure; Aa--judged to be of "high quality by 
all standards" but as to which margins of protection or other elements make 
long-term risks appear somewhat larger than Aaa-rated Municipal Bonds; 
together with Aaa group they comprise what are generally known as "high grade 
bonds"; A--possess many favorable investment attributes and are considered 
"upper medium grade obligations." Factors giving security to principal and 
interest of A-rated Municipal Bonds are considered adequate, but elements may 
be present which suggest a susceptibility to impairment sometime in the 
future; Baa--considered as medium grade obligations; i.e., they are neither 
highly protected nor poorly secured; interest payments and principal security 
appear adequate for the present but certain protective elements may be 
lacking or may be characteristically unreliable over any great length of 
time; Ba-- protection of principal and interest payments may be very 
moderate; judged to have speculative elements; their future cannot be 
considered as well-assured; B--lack characteristics of a desirable 
investment; assurance of interest and principal payments over any long period 
of time may be small; Caa--poor standing; may be in default or there may be 
present elements of danger with respect to principal and interest; 
Ca--speculative in a high degree; often in default; C--lowest rated class of 
bonds; issues so rated can be regarded as having extremely poor prospects for 
ever attaining any real investment standing.

designated Moody's Investment Grade ("MIG"). Symbols used will be as follows:
MIG-1--Best quality, enjoying strong protection from established cash flows of
funds for their servicing or from established and broad-based access to the
market for refinancing, or both; MIG-2--High quality with margins of
protection ample although not so large as in the preceding group.

   Description of Moody's highest commercial paper rating: Prime-1 
("P-1")--Judged to be of the best quality. Their short-term debt obligations 
carry the smallest degree of investment risk. 

   Excerpts from Standard & Poor's Corporation's Municipal Bond ratings: 
AAA--has the highest rating assigned by S&P; extremely strong capacity to pay 
principal and interest; AA--has a very strong capacity to pay interest and 
repay principal and differs from the higher rated issues only in a small 
degree; A--has a strong capacity to pay principal and interest, although 
somewhat more susceptible to the adverse changes in circumstances and 
economic conditions; BBB--regarded as having an adequate capacity to pay 
principal and interest; normally exhibit adequate protection parameters but 
adverse economic conditions or changing circumstances are more likely to lead 
to a weakened capacity to pay principal and interest than for bonds in A 
category; BB--B--CCC--CC--predominantly speculative with respect to capacity 
to pay interest and repay principal in accordance with terms of obligation; 
BB is being paid; D--in default, and payment of principal and/or interest is 
in arrears. 

   The ratings from "AA" to "B" may be modified by the addition of a plus or 
minus sign to show relative standing within the major rating categories. 

   Excerpt from Standard & Poor's Corporation's rating of municipal note 
issues: SP-1+ --very strong capacity to pay principal and interest; 
SP-1--strong capacity to pay principal and interest. 

   Description of S&P's highest commercial papers ratings: A-1+--This 
designation indicates the degree of safety regarding timely payment is 
overwhelming. A-1--This designation indicates the degree of safety regarding 
timely payment is very strong.

                    APPENDIX B-MUNICIPAL LEASE OBLIGATIONS 


   Each Portfolio may invest in municipal lease obligations. Such securities 
will be treated as liquid (excluding short-term obligations) under the 
following guidelines have been established by the Board of Trustees: 


       1. The obligation has been rated "investment grade" by at least one 
   NRSRO and is considered to be investment grade by the investment adviser. 
       2. The obligation is secured by payments from a governmental lessee 
   which is generally recognized and has debt obligations which are actively 
   traded by a minimum of five broker/dealers. 
       3. At least $25 million of the lessee debt is outstanding either in a 
   single transaction or on parity, and owned by a minimum of five 
   institutional investors. 
       4. The investment adviser has determined that the obligation, or a 
   comparable lessee security, trades in the institutional marketplace at 
   least periodically, with a bid/offer spread of 20 basis points or less. 
       5. The governmental lessee has a full faith and credit general 
   obligation rating of at least "A-" as published by at least one NRSRO or 
   as determined by the investment adviser. If the lessee is a state 
   government, the general obligation rating must be at least BAA1, BBB+, or 
   equivalent, as determined above. 
       6. The projects to be financed by the obligation are determined to be 
   critical to the lessee's ability to deliver essential services. 
       7. Specific legal features such as covenants to maintain the tax-exempt 
   status of the obligation, covenants to make lease payments without the 
   right of offset or counterclaim, covenants to return leased property to 
   the lessor in the event of non-appropriation, insurance policies, debt 
   service reserve fund, are present. 
       8. The lease must be "triple net" (i.e.--lease payments are net of 
   property maintenance, taxes and insurance). 
       9. If the lessor is a private entity, there must be a sale and absolute 
   assignment of rental payments to the trustee, accompanied by a legal 
   opinion from recognized bond counsel that lease payments would not be 
   considered property of the lessor's estate in the event of lessor's 
   bankruptcy. 

                                                                          B-19
