1 These amounts reflect reductions by the Investment Manager, which are
guaranteed through at least April 30, 1996. If there were no such reductions,
the maximum management fee for the Schwab Money Market Fund, Schwab Government
Money Fund, Schwab U.S. Treasury Money Fund and Schwab Tax-Exempt Money Fund
would have been 0.42%, 0.44%, 0.46% and 0.43%, respectively, for the fiscal year
ended December 31, 1994. (See Management of the Funds--Fees and Expenses).
    
 
2 See "Management of the Funds--Fees and Expenses" for information regarding the
differing expenses for the multiple classes of shares of the Schwab Tax-Exempt
Money Fund.
 
   
3 Schwab currently imposes no fees for opening and maintaining a Schwab
brokerage account. Effective October 1, 1995, Schwab will institute a $1,000
minimum equity requirement for brokerage accounts ($500 for custodial accounts).
A quarterly fee of $7.50 will be charged on accounts that fall below the
minimum. This fee, if applicable, will be charged at the end of each quarter and
will be waived if there has been one commissionable trade within the last six
months, or if the shareholder's combined account balances at Schwab total
$10,000 or more. Schwab imposes no fees for opening and maintaining a Schwab
One(R) account with a minimum balance of $5,000. Schwab One accounts with
balances below $5,000 are subject to a monthly fee of $5 if there have been
fewer than two commissionable trades within the last 12 months. Schwab
Individual Retirement Accounts with balances of $10,000 or more by September 15,
1995 are not charged Schwab's $29 annual IRA account fee for the life of the
account. Schwab Keogh plans are currently charged an annual fee of $45. See "How
to Purchase Shares" for information regarding the differing minimum balance and
minimum investment requirements of the multiple classes of shares of the Schwab
Tax-Exempt Money Fund.
    
 
   
4 These amounts reflect the guarantee by the Investment Manager and Schwab that,
through at least April 30, 1996, the total fund operating expenses of the Schwab
Money Market Fund, Schwab Government Money Fund, Schwab U.S. Treasury Money Fund
and the Schwab Tax-Exempt Money Fund-Sweep Shares will not exceed 0.75%, 0.75%,
0.65% and 0.66%, respectively. Without similar guarantees, which were in effect
during the prior fiscal year as to the Schwab Money Market Fund,

 
                                        3

Schwab Government Money Fund, Schwab Tax-Exempt Money Fund-Sweep Shares and the
Schwab U.S. Treasury Money Fund, total fund operating expenses would have been
0.90%, 0.92%, 0.91%, and 1.00%, respectively.

THE PURPOSE OF THE PRECEDING TABLE IS TO ASSIST INVESTORS IN UNDERSTANDING THE
VARIOUS COSTS AND EXPENSES THAT AN INVESTOR IN ANY OF THE FUNDS WILL BEAR
DIRECTLY OR INDIRECTLY. This example reflects the guarantee by the Investment
Manager and Schwab that, through at least April 30, 1996, the total fund
operating expenses of the Schwab Money Market Fund, Schwab Government Money
Fund, Schwab U.S. Treasury Money Fund and the Sweep Shares of the Schwab
Tax-Exempt Money Fund will not exceed 0.75%, 0.75%, 0.65% and 0.66%,
respectively. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN. The
example assumes a 5% annual rate of return pursuant to requirements of the SEC.
THIS HYPOTHETICAL RATE OF RETURN IS NOT INTENDED TO BE REPRESENTATIVE OF PAST OR
FUTURE PERFORMANCE.

expenses not been reduced and absorbed, the ratio of expenses to average net
assets for the Schwab Money Market Fund for the periods ended December 31, 1994,
1993, 1992, 1991 and 1990 would have been 0.90%, 0.91%, 0.92%, 0.94% and 0.95%*,
respectively, and the ratio of net investment income to average net assets would
have been 3.52%, 2.46%, 3.18%, 5.36% and 7.38%*, respectively. With respect to
the Schwab Government Money Fund, the ratio of expenses to average net assets
for the periods ended December 31, 1994, 1993, 1992, 1991 and 1990 would have
been 0.92%, 0.93%, 0.94%, 0.95% and 0.96%*, respectively, and the ratio of net
investment income to average net assets would have been 3.38%, 2.43%, 3.14%,
5.13% and 7.25%*, respectively. With respect to the Schwab U.S. Treasury Money
Fund, the ratio of expenses to average net assets for the periods ended December
31, 1994, 1993, 1992 and 1991 would have been 1.00%, 1.05%, 1.15% and 4.11%*,
respectively, and the ratio of net investment income to average net assets would
have been 3.25%, 2.10%, 2.35% and 0.24%*, respectively. With respect to the
Schwab Tax-Exempt Money Fund--Sweep Shares, the ratio of expenses to average net
assets for the periods ended December 31, 1994, 1993, 1992, 1991 and 1990 would
have been 0.91%, 0.93%, 0.94%, 0.95% and 0.95%*, respectively, and the ratio of
net investment income to average net assets would have been 2.05%, 1.62%, 2.14%,
3.59% and 5.01%*, respectively.
 
MATCHING THE FUNDS TO YOUR INVESTMENT NEEDS
 
   
The Funds may be appropriate for a variety of investment programs which can be
long-term or short-term in nature. While a Fund is not a substitute for building
an investment portfolio tailored to an individual's investment needs and risk
tolerance, it can be used as a high-quality, conveniently liquid money market
investment for your brokerage account cash when it is not fully invested in
other securities. The Schwab Tax-Exempt Money Fund would not be an appropriate
investment for retirement plans such as IRAs and Keogh plans.
    
--------------------------------------------------------------------------------
THE FUNDS MAY BE ESPECIALLY SUITABLE FOR SHORT-TERM INVESTORS.
--------------------------------------------------------------------------------
 
Because the Funds are designed to provide liquidity and stability of capital, as
well as automatic investment of free credit balances, they may be especially
suitable for investors with short-term investment objectives, including those
who are awaiting an opportune time to invest in the equity and/or bond markets.
--------------------------------------------------------------------------------
THE FUNDS MAY ALSO BE APPROPRIATE FOR LONG-TERM INVESTORS.
--------------------------------------------------------------------------------
 
The Funds may also be appropriate for long-term investors seeking low-risk
investment alternatives which are designed to provide current (and in the case
of the Schwab Tax-Exempt Money Fund, federally tax-free) income.
 
In addition to the Sweep Shares of the Schwab Tax-Exempt Money Fund, Schwab also
offers Value Advantage Shares of the Fund, pursuant to a multiple class plan
(the "Plan") adopted by the Board of Trustees of the Schwab Fund Family. Under
the Plan, Value Advantage Shares of the Schwab Tax-Exempt Money Fund, which are
not available through automatic ("sweep") investment programs,
 
   * Annualized
 
                                        6
<PAGE>   7
 
are subject to lower transfer agency expenses than the Sweep Shares of the Fund.
In addition, the minimum investment and minimum account balance requirements of
the Value Advantage Shares of the Schwab Tax-Exempt Money Fund are higher than
those applicable to the Sweep Shares. See "Management of the Funds -- Fees and
Expenses" and "How to Purchase Shares."
 
For information regarding Value Advantage Shares, call your local Schwab office
or 800-2 NO-LOAD. You may also obtain information about Value Advantage Shares
from your Schwab broker.
 
INVESTMENT OBJECTIVES AND POLICIES
-------------------------------------------------------------------------------
THE SCHWAB MONEY MARKET FUND SEEKS MAXIMUM CURRENT
INCOME CONSISTENT WITH STABILITY OF CAPITAL.
-------------------------------------------------------------------------------
 
THE SCHWAB MONEY MARKET FUND. The Schwab Money Market Fund seeks maximum current
income consistent with stability of capital. The Fund pursues its objective by
investing exclusively in the following types of U.S. dollar-denominated money
market instruments which mature in 12 months or less and which the Investment
Manager has determined to present minimal credit risk:
 
1. Bank certificates of deposit, time deposits or bankers' acceptances of
   domestic banks (including their foreign branches) and Canadian chartered
   banks having capital, surplus and undivided profits in excess of $100
   million.
 
2. Bank certificates of deposit, time deposits or bankers' acceptances of United
   States branches of foreign banks and foreign branches of foreign banks having
   capital, surplus and undivided profits in excess of $100 million.
 
3. Commercial paper rated in one of the two highest rating categories by Moody's
   Investors Service ("Moody's"), Standard & Poor's Corporation ("S&P"), Duff &
   Phelps, Inc. ("Duff"), Fitch Investors Service, Inc. ("Fitch"), or any other
   nationally recognized statistical rating organization ("NRSRO") or commercial
   paper or notes of issuers with an unsecured debt issue outstanding currently
   rated in one of the two highest rating categories by any NRSRO where the
   obligation is on the same or a higher level of priority and collateralized to
   the same extent as the rated issue. Each Fund may also invest in other
   corporate obligations such as publicly traded bonds, debentures and notes
   rated in one of the two highest rating categories by any NRSRO and other
   similar securities which, if unrated by any NRSRO, are determined by the
   Investment Manager, using guidelines approved by the Board of Trustees, to be
   at least equal in quality to one or more of the above referenced securities.
   (For a description of the ratings, see "Appendix--Ratings of Investment
   Securities" in the Statement of Additional Information.)
 
4. Obligations of, or guaranteed by, the United States or Canadian governments,
   their agencies or instrumentalities.
 
5. Repurchase agreements involving obligations that are suitable for investment
   under the categories set forth above.
 
                                        7
<PAGE>   8
 
To the extent the Schwab Money Market Fund purchases Eurodollar certificates of
deposit, consideration will be given to their marketability and possible
restrictions on international currency transactions and to regulations imposed
by the domicile country of the foreign issuer. Eurodollar certificates of
deposit may not be subject to the same regulatory requirements as certificates
of deposit issued by U.S. banks and associated income may be subject to the
imposition of foreign taxes.
 
Investments in securities of foreign issuers or securities principally traded
overseas may involve certain special risks due to foreign economic, political
and legal developments, including favorable or unfavorable changes in currency
exchanges rates, exchange control regulations (including currency blockage),
expropriation of assets or nationalization, imposition of withholding taxes on
dividend or interest payments, and possible difficulty in obtaining and
enforcing judgments against foreign entities. Furthermore, issuers of foreign
securities are subject to different, often less comprehensive, accounting,
reporting and disclosure requirements than domestic issuers. The securities of
some foreign companies and foreign securities markets are less liquid and at
times more volatile than securities of comparable U.S. companies and U.S.
securities markets. Foreign brokerage commissions and other fees are also
generally higher than in the United States. There are also special tax
considerations which apply to securities of foreign issuers and securities
principally traded overseas.
 
The Schwab Money Market Fund may invest in commercial paper issued in reliance
on the so-called "private placement" exemption from registration afforded by
Section 4(2) of the Securities Act of 1933, and resold to qualified
institutional buyers under Securities Act Rule 144A ("Section 4(2) paper").
Section 4(2) paper is restricted as to disposition under the federal securities
laws, and generally is sold to institutional investors such as the Schwab Money
Market Fund who agree that they are purchasing the paper for investment and not
with a view to public distribution. Any resale by the purchaser must be in an
exempt transaction and may be accomplished in accordance with Rule 144A. Section
4(2) paper normally is resold to other institutional investors like the Fund
through or with the assistance of the issuer or investment dealers who make a
market in the Section 4(2) paper, thus providing liquidity. The Schwab Money
Market Fund will invest no more than 10% of its assets in Section 4(2) paper and
illiquid securities unless the Investment Manager determines, by continuous
reference to the appropriate trading markets and pursuant to guidelines approved
by the Board of Trustees, that any Section 4(2) paper held by the Fund in excess
of this level is liquid.
 
Because it is not possible to predict with assurance exactly how this market for
Section 4(2) paper sold and offered under Rule 144A will continue to develop,
the Investment Manager, pursuant to the guidelines approved by the Board of
Trustees, will carefully monitor the Fund's investments in these securities,
focusing on such important factors, among others, as valuation, liquidity, and
availability of information. Investments in Section 4(2) paper could have the
effect of reducing the Fund's liquidity to the extent that qualified
institutional buyers become for a time uninterested in purchasing these
restricted securities.

    
The Fund may invest in asset-backed commercial paper. Repayment of this type of
commercial paper is intended to be obtained from an identified pool of assets,
including automobile receivables, credit-card receivables and other types of
receivables. Asset-backed commercial paper is issued by a special purpose
vehicle (usually a corporation) that has been established for the purpose of
issuing the
 
                                        8
<PAGE>   9
 
commercial paper and purchasing the underlying pool of assets. The issuer of the
commercial paper bears the direct risk of prepayment on the receivables
constituting the underlying pool of assets. Credit support for asset-backed
securities may be based on the underlying assets or provided by a third party.
Credit enhancement techniques include letters of credit, insurance bonds,
limited guarantees (which are generally provided by the issuer), and over
collateralization. Asset-backed securities purchased by the Fund will be subject
to the same quality requirements as other securities purchased by the Fund. For
more information regarding the Fund's investments, see the section of this
Prospectus entitled "Share Price Calculation."
    
----------------------------------------------------------------------------
THE SCHWAB GOVERNMENT MONEY FUND SEEKS MAXIMUM
CURRENT INCOME CONSISTENT WITH STABILITY OF CAPITAL.
----------------------------------------------------------------------------
 
THE SCHWAB GOVERNMENT MONEY FUND. The Schwab Government Money Fund seeks maximum
current income consistent with stability of capital. The Fund pursues its
objective by investing exclusively in U.S. Treasury bills, notes, bonds and
other obligations issued or guaranteed by the United States Government, its
agencies, or instrumentalities, and repurchase agreements covering such
obligations. All securities purchased mature within 12 months or less. Some
securities issued by U.S. Government agencies or instrumentalities are supported
only by the credit of the agency or instrumentality, for example, those issued
by the Federal Home Loan Bank, while others, such as those issued by the Federal
National Mortgage Association, Farm Credit System and Student Loan Marketing
Association, have an additional line of credit with the U.S. Treasury.
Short-term U.S. Government obligations generally are considered to be among the
safest short-term investments. The Government guarantee of the securities owned
by the Schwab Government Money Fund, however, does not guarantee the net asset
value of the Fund's shares, which the Fund seeks to maintain at $1.00 per share.
(See "Share Price Calculation.") Also, with respect to securities supported only
by the credit of the issuing agency or instrumentality or by an additional line
of credit with the U.S. Treasury, there is no guarantee that the U.S. Government
will provide support to such agencies or instrumentalities. Accordingly, such
securities may involve risk of loss of principal and interest.
--------------------------------------------------------------------------------
THE SCHWAB U.S. TREASURY MONEY FUND SEEKS HIGH CURRENT
INCOME CONSISTENT WITH LIQUIDITY AND STABILITY OF CAPITAL.
--------------------------------------------------------------------------------
 
THE SCHWAB U.S. TREASURY MONEY FUND. The investment objective of the Schwab U.S.
Treasury Money Fund is high current income consistent with liquidity and
stability of capital. The Fund pursues its objective by investing solely in
United States Treasury notes, bills and other direct obligations of the United
States Treasury that are backed by the "full faith and credit" of the United
States Government. The Fund will only purchase securities that mature in 397
days or less, or which have a variable rate of interest readjusted no less
frequently than every 397 days. Fund shares themselves are not subject to any
U.S. Government guarantee. The Fund does not enter into repurchase agreements,
nor does it purchase obligations of agencies or instrumentalities of the U.S.
Government. The Fund may hold its investments to maturity and receive the entire
face amount of the security, or the Fund may sell its investments at a gain or
loss before maturity to meet redemptions or for other investment purposes.

--------------------------------------------------------------------------------
THE SCHWAB TAX-EXEMPT MONEY FUND SEEKS TO PROVIDE ITS SHAREHOLDERS
WITH MAXIMUM CURRENT INCOME EXEMPT FROM FEDERAL INCOME TAXES.
--------------------------------------------------------------------------------
 
THE SCHWAB TAX-EXEMPT MONEY FUND. The investment objective of the Schwab
Tax-Exempt Money Fund is maximum current income that is exempt from federal
income taxes consistent with stability of capital. The Fund pursues its
objective primarily by investing in short-term, high quality municipal
obligations the income from which is exempt from federal income taxes.
 
Under normal market conditions, the Fund attempts to invest 100%, and will
invest at least 80%, of its total assets in debt obligations issued by or on
behalf of states, territories and possessions of the United States and the
District of Columbia and their political subdivisions, agencies and
instrumentalities that generate interest exempt from federal income tax and not
treated as a tax preference item for purposes of the federal alternative minimum
tax ("Municipal Securities").
 
Dividends representing net interest income received by the Schwab Tax-Exempt
Money Fund on Municipal Securities will be exempt from federal income tax when
distributed to the Fund's shareholders. Such dividend income may be subject to
state and local taxes. (See "Distributions And Taxes--The Schwab Tax-Exempt
Money Fund.")
 
The Schwab Tax-Exempt Money Fund will invest only in Municipal Securities which
at the time of purchase: (a) are rated within the two highest rating categories
for municipal commercial paper or short-term municipal securities assigned by
any NRSRO; (b) are guaranteed or insured by the U.S. Government as to the
payment of principal and interest; (c) are fully collateralized by an escrow of
U.S. Government securities acceptable to the Fund's Investment Manager; or (d)
are unrated by any NRSRO, if they are determined by the Investment Manager,
using guidelines approved by the Board of Trustees, to be at least equal in
quality to one or more of the above referenced securities. (For a description of
the ratings, see "Appendix--Ratings of Investment Securities" in the Statement
of Additional Information.)
 
After its purchase by the Fund, a Municipal Security may cease to be rated or
its rating may be reduced below that required for purchase by the Fund. Neither
event would under all circumstances require the elimination of such an
obligation from the Fund's investment portfolio. However, the obligation
generally would be retained only if such retention was determined by the Board
of Trustees to be in the best interests of the Fund.
 
From time to time, as a defensive measure, the Schwab Tax-Exempt Money Fund may
invest any or all of its assets in taxable "temporary investments" which
include: obligations of the U.S. Government, its agencies, or instrumentalities;
debt securities rated within the two highest rating categories by any NRSRO;
commercial paper rated in the two highest rating categories by such rating
services; certificates of deposit of domestic banks having capital, surplus, and
undivided profits in excess of $100 million; and any of the foregoing temporary
investments subject to repurchase agreements. While purchase by the Fund of
certain temporary investments could cause it to generate dividends taxable to
shareholders as ordinary income (see "Distributions and Taxes"), it is the
Fund's primary intention to produce dividends which are not subject to federal
income taxes.
 
                                       10

The investment objective of each Fund and the investment policies set forth
above are fundamental. They, along with certain investment restrictions adopted
by the Funds (see "Investment Restrictions" in the Statement of Additional
Information), cannot be changed without approval by holders of a majority of a
Fund's outstanding voting shares, as defined in the Investment Company Act of
1940 (the "1940 Act").
 
MUNICIPAL SECURITIES AND INVESTMENT TECHNIQUES
 
The two principal classifications of Municipal Securities which may be held by
the Schwab Tax-Exempt Money Fund are "general obligation" securities and
"revenue" securities. General obligation securities are secured by the issuer's
pledge of its full credit and taxing power for the payment of principal and
interest. Revenue securities 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 tax or other specific revenue source such as the user of the
facility being financed. Industrial development bonds held by the Fund are in
most cases revenue bonds and are not payable from the unrestricted revenues of
the issuer. Among other types of instruments, the Fund may purchase tax-exempt
commercial paper and short-term municipal notes such as tax anticipation notes,
bond anticipation notes, revenue anticipation notes, construction loan notes and
other forms of short-term loans. Such notes are issued with a short-term
maturity in anticipation of the receipt of tax payments, the proceeds of bond
placements, or other revenues. A more detailed discussion of Municipal
Securities and the ratings outlined above is contained in the Statement of
Additional Information.
 
In seeking to achieve its investment objective, the Schwab Tax-Exempt Money Fund
may invest all or any part of its assets in Municipal Securities that are
industrial development bonds. Moreover, although the Fund does not currently
intend to do so on a regular basis, it may invest more than 25% of its assets in
Municipal Securities that are repayable out of revenue streams generated from
economically related projects or facilities, if such investment is deemed
necessary or appropriate by the Fund's Investment Manager. To the extent that
the Fund's assets are concentrated in Municipal Securities payable from revenues
on economically related projects and facilities, the Fund will be subject to the
risks presented by such projects to a greater extent than it would be if the
Fund's assets were not so concentrated.
 
The Fund may invest in municipal leases, which are obligations issued by state
and local governments or authorities to finance the acquisition of equipment and
facilities. These obligations may take the form of a lease, an installment
purchase contract, a conditional sales contract, or a participation interest in
any of the above. Investments in municipal leases may be considered to be
illiquid. The Fund will limit its investment in municipal leases to no more than
25% of its total assets (no more than 10% of which may be illiquid municipal
leases). Municipal leases are subject to "nonappropriation risk," which is the
risk that the municipality may terminate the lease in the event that the
municipality's appropriating body does not allocate the funds necessary to make
lease payments. In such circumstances, the lessor is typically entitled to
repossess the property. The private sector value of the property is, however,
generally less than the value of the property to the municipality. The
Investment Manager, pursuant to guidelines established by the Board of Trustees,
is responsible for
 
                                       11
<PAGE>   12
 
determining the credit quality of unrated municipal leases, on an ongoing basis,
including an assessment of the likelihood of whether the lease will be
terminated.
 
   
The Fund may also invest up to 25% of its assets in synthetic variable or
floating rate municipal securities. These securities generally comprise the
following elements in a trust: (i) a fixed-rate municipal bond (of any
duration); (ii) a right to put the bond at par value on 7-days notice or after a
specific interval of time depending on the terms of the synthetic security; and
(iii) a contractual agreement pursuant to which the investing Fund and the
issuer determine the lowest rate that would permit the bond to be remarketed at
par, taking into account the put right. The trustee of the trust is generally a
bank trust department.
    
 
   
These securities may also include tender option bond trust receipts, in which a
fixed-rate municipal bond (or group of bonds) is placed into a trust from which
two classes of trust receipts are issued, which represent proportionate
interests in the underlying bond(s). Interest payments are made on the bond(s)
based upon a predetermined rate. Under certain circumstances, the holder of a
trust receipt may also participate in any gain or loss on the sale of such
bond(s). Tender option bond trust receipts are considered to be Municipal
Securities for purposes of the Fund's policy to invest at least 80% of its total
assets in Municipal Securities. Tender option bond trust receipts generally are
structured as private placements and, accordingly, may be deemed to be
restricted securities for purposes of the Fund's investment limitations.
    
 
   
In addition, the Schwab Tax-Exempt Money Fund may acquire "stand-by commitments"
with respect to Municipal Securities held in its portfolio. Under a stand-by
commitment, a dealer agrees to purchase at the Fund's option specified Municipal
Securities at a price equal to their amortized cost value plus accrued interest.
Securities may cost more with Standby Commitments than without them. The Fund's
policy is to enter into Standby Commitments only with issuers, banks or dealers
that are determined by the Investment Manager to present minimal credit risks.
If an issuer, bank or dealer should default on its obligations to repurchase an
underlying security, the Fund might be unable to recover all or a portion of any
loss sustained from having to sell the securities elsewhere. The Fund will
acquire stand-by commitments solely to facilitate portfolio liquidity and does
not intend to exercise its rights thereunder solely for trading purposes.
    
 
Opinions relating to the validity of Municipal Securities and to the exemption
of interest thereon from federal income tax are rendered by bond counsel to the
respective issuers at the time of issuance. The Schwab Tax-Exempt Money Fund and
the Investment Manager will not review the proceedings relating to the issuance
of Municipal Securities or the bases for such opinions.
 
OTHER INVESTMENT TECHNIQUES--"WHEN-ISSUED" SECURITIES, REPURCHASE AGREEMENTS AND
VARIABLE RATE SECURITIES. Each Fund may purchase securities on a "when-issued"
or "delayed delivery" basis. When-issued or delayed delivery securities are
securities purchased for future delivery at a stated price and yield. A Fund
will generally not pay for such securities or start earning interest on them
until they are received. Securities purchased on a when-issued or delayed
delivery basis are recorded as an asset and are subject to changes in value
based upon changes in the general level of interest rates. Each Fund will not
invest more than 25% of its assets in when-issued or delayed delivery
securities, does not intend to purchase such securities for speculative purposes
and will make commitments to
 
                                       12
<PAGE>   13
 
purchase securities on a when-issued or delayed delivery basis with the
intention of actually acquiring the securities. However, each Fund reserves the
right to sell acquired when-issued or delayed delivery securities before their
settlement dates if deemed advisable.
 
   
Each Fund (except the Schwab U.S. Treasury Money Fund) may invest in repurchase
agreements, which are instruments under which a Fund acquires ownership of a
security from a broker-dealer or bank that agrees to repurchase the security at
a mutually agreed upon time and price (which price is higher than the purchase
price), thereby determining the yield during the Fund's holding period. Maturity
of the securities subject to repurchase may exceed one year. In the event of a
bankruptcy or other default of a repurchase agreement counterparty, a Fund might
have expenses in enforcing its rights, and could experience losses, including a
decline in the value of the underlying securities and loss of income. The Fund
will only enter into repurchase agreements with banks and other recognized
financial institutions such as broker/dealers which are deemed by the Investment
Manager to be creditworthy under guidelines adopted by the Board of Trustees. A
Fund will not purchase illiquid securities, including time deposits and
repurchase agreements maturing in more than 7-days if, as a result thereof, more
than 10% of the Fund's net assets valued at the time of the transaction would be
invested in such securities.
    
 
   
Each Fund may invest in instruments having rates of interest that are adjusted
periodically or which "float" continuously according to formulae intended to
minimize fluctuation in values of the instruments ("Variable Rate Securities").
The interest rate of Variable Rate Securities ordinarily is determined by
reference to, or is a percentage of, an objective standard such as a bank's
prime rate, the 90-day U.S. Treasury Bill rate, or the rate of return on
commercial paper or bank certificates of deposit. Generally, the changes in the
interest rate on Variable Rate Securities reduce the fluctuation in the market
value of such securities. Accordingly, as interest rates decrease or increase,
the potential for capital appreciation or depreciation is less than for
fixed-rate obligations. Some Variable Rate Securities ("Variable Rate Demand
Securities") have a demand feature entitling the purchaser to resell the
securities at an amount approximately equal to amortized cost or the principal
amount thereof plus accrued interest. As is the case for other Variable Rate
Securities, the interest rate on Variable Rate Demand Securities varies
according to some objective standard intended to minimize fluctuation in the
values of the instruments. Each Fund determines the maturity of Variable Rate
Securities in accordance with SEC rules which allow the Fund to consider certain
of such instruments as having maturities shorter than the maturity date on the
face of the instrument. Under such rules, the maturity date may be considered to
be the longer of the period remaining until the next readjustment of the
interest rate or the period remaining until the principal amount can be
recovered through demand.
    
 
None of the Funds may borrow money except as a temporary measure for
extraordinary or emergency purposes, and then only in an amount up to one-third
of the value of its total assets in order to meet redemption requests. Any
borrowings under this provision will not be collateralized, except that the
Schwab Tax-Exempt Money Fund may pledge up to 10% of its net assets, and the
Schwab U.S. Treasury Money Fund may pledge up to 33% of its net assets, to
secure borrowings. No Fund will borrow for leverage purposes.

Participation interests in Municipal Securities and other derivative securities
eligible for purchase by the Funds involve special risks, including a risk that
the Internal Revenue Service may characterize some or all of the interest paid
on such securities to the Fund as taxable. There is also an increased risk, most
typically associated with "municipal lease" obligations, that a municipality
will not appropriate the funds necessary to make the scheduled payments on, or
may seek to cancel or otherwise avoid its obligations under, the lease that
supports the security owned by the Fund.
    
 
MANAGEMENT OF THE FUNDS
 
   
Responsibility for overall management of the Funds rests with the trustees and
officers of the Schwab Fund Family. Professional investment management for each
Fund is provided by the Investment Manager, Charles Schwab Investment
Management, Inc., 101 Montgomery Street, San Francisco, CA 94104. The Investment
Manager provides a continuous investment program, including general investment
and economic advice regarding each Fund's investment strategies, manages each
Fund's investment portfolio and performs expense management, accounting and
recordkeeping, and other services necessary to the operation of each Fund and
the Schwab Fund Family. The Investment Manager, formed in 1989, is a
wholly-owned subsidiary of The Charles Schwab Corporation and is the investment
adviser and administrator of the SchwabFunds(R) mutual funds. As of July 31,
1995, the SchwabFunds had aggregate net assets in excess of $28 billion.
    
 
Charles Schwab & Co., Inc. ("Schwab" or the "Transfer Agent"), 101 Montgomery
Street, San Francisco, CA 94104, serves as shareholder services agent and
transfer agent for the Funds. Schwab provides information and services to
shareholders, which include reporting share ownership, sales and dividend
activity (and associated tax consequences), responding to daily inquiries,
effecting the transfer of Fund shares and facilitating effective cash management
of shareholders' Schwab account balances. It furnishes such office space and
equipment, telephone facilities, personnel and informational literature
distribution as is necessary or appropriate in providing shareholder and
transfer agency information and services. Schwab is also the Funds' distributor,
but receives no compensation for its services as such.
 
   
Schwab was established in 1971 and is one of America's largest discount brokers.
The firm provides low-cost securities brokerage and related financial services
to over 2.5 million active customer accounts and has over 200 offices. Schwab
also offers convenient access to financial information services and provides
products and services that help investors make investment decisions. Schwab is a
wholly-owned subsidiary of The Charles Schwab Corporation. Charles R. Schwab is
the founder, Chairman and Chief Executive Officer and a director of The Charles
Schwab Corporation and, as of July 31, 1995 the beneficial owner of
approximately 20.5% of the outstanding shares of that corporation. Mr. Schwab
may be deemed to be a controlling person of Schwab and the Investment Manager.
    
 
FEES AND EXPENSES. Pursuant to its Investment Advisory and Administration
Agreement with the Schwab Fund Family, the Investment Manager receives from the
Schwab Money Market Fund a graduated annual fee, payable monthly, of 0.46% of
the Fund's average daily net assets not in excess of $2 billion, 0.45% of such
net assets over $2 billion but not in excess of $3 billion, and 0.40% of such
net assets over $3 billion; the Investment Manager receives from the Schwab
Government Money
 
                                       14
<PAGE>   15
 
Fund and the Schwab Tax-Exempt Money Fund a graduated annual fee, payable
monthly, of 0.46% of each Fund's average daily net assets not in excess of $1
billion, 0.41% of such net assets over $1 billion but not in excess of $2
billion and 0.40% of such net assets over $2 billion. Pursuant to a separate but
substantially similar Investment Advisory and Administration Agreement with the
Schwab Fund Family, the Investment Manager receives from the Schwab U.S.
Treasury Money Fund a graduated annual fee, payable monthly, of 0.46% of the
Fund's average daily net assets not in excess of $1 billion, 0.41% of such net
assets over $1 billion but not in excess of $2 billion, and 0.40% of such net
assets over $2 billion.
 
   
The Investment Manager has guaranteed that, at least through April 30, 1996, the
investment management fee of the Schwab Money Market Fund, Schwab Government
Money Fund, Schwab U.S. Treasury Money Fund and Schwab Tax-Exempt Money Fund
will not exceed 0.29%, 0.29%, 0.19% and 0.20%, respectively, of each such Fund's
average daily net assets. In addition, the Investment Manager and Schwab have
guaranteed that, through at least April 30, 1996, the total fund operating
expenses of the Schwab Money Market Fund, Schwab Government Money Fund, Schwab
U.S. Treasury Money Fund and the Sweep Shares of the Schwab Tax-Exempt Money
Fund will not exceed 0.75%, 0.75%, 0.65% and 0.66%, respectively. The effect of
these guarantees is to maintain or lower the expenses and thus maintain or
increase such Fund's total return to shareholders. For the fiscal year ended
December 31, 1994, the Schwab Money Market Fund, the Schwab Government Money
Fund, the Schwab U.S. Treasury Money Fund, and the Schwab Tax-Exempt Money Fund
paid investment management fees equal to 0.28%, 0.28%, 0.19%, and 0.19%,
respectively, of each such Fund's average daily net assets and paid total fund
operating expenses of 0.74%, 0.74%, 0.65% and 0.65%, respectively, of each such
Fund's average daily net assets.
    
 
For the Schwab Money Market Fund, Schwab Government Money Fund and Schwab U.S.
Treasury Money Fund for transfer agency services provided, the Transfer Agent
receives an annual fee, payable monthly, of 0.25% of the average daily net
assets of each such Fund. In addition, for shareholder services provided, Schwab
receives an annual fee, payable monthly, of 0.20% of the average daily net
assets of each such Fund. For the Sweep Shares of the Schwab Tax-Exempt Money
Fund, for transfer agency services provided, the Transfer Agent receives an
annual fee, payable monthly, of 0.25% of the average daily net assets of that
class. In addition, for shareholder services provided, Schwab receives an annual
fee, payable monthly of 0.20% of the average daily net assets of the class. For
the Value Advantage Shares of the Schwab Tax-Exempt Money Fund, the Transfer
Agent receives an annual fee of 0.05% of the average daily net assets of that
class' shares of beneficial interest. PNC Bank is the Funds' Custodian.
 
   
The Schwab Fund Family pays the expenses of its operations. These expenses are
generally allocated among the Schwab Fund Family's investment portfolios
("Series") on the basis of relative net assets at the time of allocation.
However, expenses directly attributable to a particular Series or class of a
Series are charged to that Series or class, respectively. The differing expenses
applicable to the Sweep Shares of the Schwab Tax-Exempt Money Fund and the Value
Advantage Shares will cause the performance of the two classes of shares of the
Fund to differ.

DISTRIBUTIONS AND TAXES
--------------------------------------------------------------------------------
EACH FUND DECLARES DAILY DIVIDENDS WHICH ARE PAID MONTHLY.
--------------------------------------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS. On each day that the net asset value per
share of a Fund is determined ("Business Day"), the Fund's net investment income
is declared as of the close of trading on the New York Stock Exchange (generally
4:00 p.m. Eastern time) as a dividend to shareholders already of record at the
previous net asset value calculation. Dividends are normally paid (and, where
applicable, reinvested) on the 15th of each month, if a Business Day, otherwise
on the next Business Day.
 
   
FEDERAL INCOME TAX INFORMATION. Each Fund has elected to be treated as a
regulated investment company under the Internal Revenue Code of 1986, as amended
(the "Code"), qualified as such, and intends to continue to so qualify. In order
to so qualify, each Fund will distribute on a current basis substantially all of
its investment company taxable income, its net exempt-interest income (if any),
and its net capital gains (if any) and will meet certain other requirements.
Such qualification relieves a Fund of liability for federal income taxes to the
extent the Fund's earnings are distributed.
    
 
All distributions are taxable to shareholders as ordinary income, except that
long-term capital gains distributions (if any) are taxable as such, regardless
of how long the shareholder has held the shares. Reinvested distributions will
be taxable as if they had been received by shareholders in cash. It is not
expected that any portion of the dividends paid by the Funds will qualify for
the corporate dividends received deduction.
 
   
Records of dividends and other distributions, purchases and redemptions will be
reflected on shareholders' regular Schwab account statements. The Funds will
notify shareholders at least annually as to the federal income tax consequences
of distributions made each year. The Funds do not expect to realize any net
long-term capital gains and, therefore, do not foresee paying any capital gains
dividends.
    
 
   
THE SCHWAB U.S. TREASURY MONEY FUND. Because this Fund will invest exclusively
in United States Treasury obligations and other securities backed by the full
faith and credit of the U.S. Government, its dividends are free from state and
local income taxes in the vast majority of states. Potential investors in this
Fund should consult their tax advisers with specific reference to their own tax
situations.
    
 
   
THE SCHWAB TAX-EXEMPT MONEY FUND. Dividends paid by the Fund that are derived
from exempt-interest income and designated by the Fund as "exempt-interest
dividends" will be treated by the Fund's shareholders as items of interest
excludable from their federal gross income. (Shareholders should consult their
own tax adviser with respect to whether exempt-interest dividends would be
excludable from gross income if the shareholder were treated as a "substantial
user" of facilities financed by an obligation held by Schwab Tax-Exempt Money
Fund or a "related person" to such user under the Code.) If a shareholder
receives an exempt-interest dividend with respect to any share held for six
months or less, any loss on the sale or exchange of such share will be
disallowed to the extent of the amount of the exempt-interest dividend. The U.S.
Treasury Department is authorized to issue regulations reducing the period to
not less than 31 days for certain regulated investment companies.
    
 
                                       16
<PAGE>   17
 
No such regulations have been issued as of the date of this Prospectus. To the
extent dividends paid to shareholders are derived from taxable income (for
example, from interest on certificates of deposit) or from short-term or
long-term capital gains, such dividends will be subject to federal income tax,
whether they are paid in the form of cash or additional shares.
 
The Fund may at times purchase Municipal Securities or California Municipal
Securities at a discount from the price at which they were initially issued. For
federal income tax purposes, some or all of this market discount will be
included in the Fund's ordinary income and will be taxable to shareholders as
such when it is distributed to them.
 
If the Schwab Tax-Exempt Money Fund holds certain "private activity bonds"
("industrial development bonds" under prior law), dividends derived from
interest on such obligations will be classified as an item of tax preference
which could subject certain shareholders to alternative minimum tax liability.
Corporate shareholders must also take all exempt-interest dividends into account
in determining "adjusted current earnings" for purposes of calculating their
alternative minimum tax liability.
 
Private activity bonds and industrial development bonds generally are bonds
issued by or on behalf of public authorities to obtain funds to provide certain
privately owned or operated facilities. Private activity bonds and industrial
development bonds also are generally limited obligation (or revenue) securities,
which means that they are payable only from the revenues derived from a
particular facility or class of facilities, or, in some cases, from some other
specific revenue source. (See "Municipal Securities" in the Statement of
Additional Information.)
 
Distributions by the Schwab Tax-Exempt Money Fund of net investment income may
be taxable to investors under state or local law as dividend income even though
all or a portion of such distributions may be derived from interest on
tax-exempt obligations which, if realized directly, would be exempt from such
income taxes.
 
Shareholders receiving Social Security benefits or Railroad Retirement Act
benefits should note that all exempt-interest dividends will be taken into
account in determining the taxability of such benefits.
 
The foregoing is only a brief summary of some of the federal and state income
tax considerations affecting the Funds and their shareholders. Accordingly,
potential investors should consult their tax advisers with specific reference to
their own tax situations.
 
SHARE PRICE CALCULATION
-------------------------------------------------------------------------------
THERE ARE NO SALES CHARGES OR TRANSACTION FEES TO PURCHASE
OR REDEEM SHARES OF THE FUNDS.
-------------------------------------------------------------------------------

    
The price of a share of a Fund class described in this Prospectus on any given
day is its "net asset value" or "NAV." For the Schwab Money Market Fund, Schwab
Government Money Fund and Schwab U.S. Treasury Money Fund, this figure is
computed by dividing total Fund assets, less any liabilities of the Fund, by the
number of shares of the Fund outstanding. For the Sweep Shares of the Schwab
Tax-Exempt Money Fund, this figure is computed by dividing total Fund assets
allocable to that class, less any liabilities allocable to the class, by the
number of Sweep Shares of the Fund
 
                                       17
<PAGE>   18
 

outstanding. The net asset value per share of a Fund is determined on each day
both the Federal Reserve Bank of New York and the New York Stock Exchange (the
"Exchange") are open for business, first at 10:00 a.m. (Eastern time), then
again as of the close of normal trading on the Exchange (generally 4:00 p.m.
Eastern time). Purchase or redemption orders and exchange requests will be
executed at the net asset value next determined after receipt by Schwab's Mutual
Fund Transfer Agency Department. While each Fund attempts to maintain its net
asset value at a constant $1.00 per share, Fund shares are not insured against a
reduction in net asset value.
    
 
Each Fund values its portfolio securities at amortized cost, which means that
they are valued at their acquisition cost (as adjusted for amortization of
premium or discount) rather than at current market value. Calculations are made
to compare the value of the Fund's investments using the amortized cost method
with market values. Except as described below, market valuations are obtained by
using actual quotations provided by third-party pricing services, market makers,
estimates of market value, or values obtained from yield data relating to
comparable classes of money market instruments published by reputable sources at
the mean between the bid and asked prices for the instruments. If a deviation of
 1/2 of 1% or more were to occur between the net asset value per share of a Fund
(or Sweep Shares for the Schwab Tax-Exempt Money Fund) calculated by reference
to market values and the $1.00 per share amortized cost value of a Fund (or
Sweep Shares for the Schwab Tax-Exempt Money Fund), or if there were any other
deviation which the Board of Trustees believed would result in a material
dilution to shareholders or purchasers, the Board of Trustees would promptly
consider what action, if any, should be initiated. While each Fund attempts to
maintain a net asset value at a constant $1.00 per share, Fund shares are not
insured against a reduction in net asset value.
 
   
The Schwab Money Market Fund has entered into a transaction with Bank of America
National Trust and Savings Association ("Bank of America") pursuant to which the
Fund is the beneficiary of an irrevocable Letter of Credit (the "Letter of
Credit") issued by Bank of America. The Letter of Credit provides a degree of
credit support for an obligation of Orange County, California held by the Fund
(the "Covered Security"). Orange County filed for protection under Chapter 9 of
the federal Bankruptcy Code in December 1995. Pursuant to the Letter of Credit,
Bank of America will make a payment to the Fund (a "Payment"), upon presentation
of a certificate as required under the Letter of Credit, if (i) the issuer of
the Covered Security defaults on a repayment of the principal amount of the
Covered Security, or (ii) the proceeds received in the disposition of the
Covered Security are less than a specified percentage of the Covered Security's
par amount. The Fund is not obligated to reimburse Bank of America for any
amount drawn under the Letter of Credit. However, the Letter of Credit does not
ensure that the Fund will receive a Payment equal to the full value of the
Covered Security. Accordingly, although the Board of Trustees has determined
that it is not in the best interests of the Fund to dispose of the Covered
Security, the Fund could incur losses as a result of its ownership of the
Covered Security.
    
 
   
The Letter of Credit will continue in effect until the earlier of (i) the date
on which Bank of America has made a Payment to the Fund equaling the total
amount available under the Letter of Credit, (ii) the date upon which the
Covered Security is fully paid, or (iii) August 1, 1996, after the Covered
Security is scheduled to currently mature.
    
 
                                       18
<PAGE>   19
 
   
The Board of Trustees has approved the payment of fees by the Fund for the
availability of the Letter of Credit, as well as revised pricing procedures that
take into account the effect of the Letter of Credit on the value of the Covered
Security (the "Pricing Procedures"). Pursuant to the Pricing Procedures, the
value of the Covered Security may be determined in good faith after
consideration of the credit support provided by the Letter of Credit in order to
cause the calculation of the Fund's market-based net asset value per share to
accurately reflect the actual value of all of its assets.
    
 
HOW THE FUNDS SHOW PERFORMANCE
 
   
From time to time the Schwab Money Market Fund, Schwab Government Money Fund and
Schwab U.S. Treasury Money Fund may advertise its yield and effective yield. In
the case of the Sweep Shares of the Schwab Tax-Exempt Money Fund only, the Fund
may advertise the yield, effective yield, taxable equivalent yield and taxable
equivalent effective yield of the Sweep Shares of the Fund. Performance figures
are based upon historical results and are not intended to indicate future
performance.
    
 
Yield refers to the income generated by a hypothetical investment in a Fund (or,
in the case of the Schwab Tax-Exempt Money Fund only, the Sweep Shares of the
Fund) over a specific 7-day period. This income is then annualized, which means
that the income generated during the 7-day period is assumed to be generated
each week over an annual period and is shown as a percentage of the hypothetical
investment.
 
Effective yield is calculated similarly, but the income earned by the investment
is assumed to be compounded weekly when annualized. The effective yield will be
slightly higher than the yield due to this compounding effect.
 
   
Taxable equivalent yield is the yield that a taxable investment must generate in
order to equal (after applicable taxes are deducted) the Sweep Shares of the
Schwab Tax-Exempt Money Fund's yield for an investor in a stated federal income
tax bracket (normally assumed to be the applicable maximum tax rate). Taxable
equivalent yield is based upon, and will be higher than, the Sweep Shares of the
Schwab Tax-Exempt Money Fund's tax-exempt yield. (See "Yield" in the Statement
of Additional Information.)
    
 
   
The taxable equivalent effective yield is computed in the same manner as is the
taxable equivalent yield, except that the effective yield is substituted for
yield in the calculation.
    
 
The performance of the Schwab Money Market Fund, Schwab Government Money Fund,
Schwab U.S. Treasury Money Fund and the Sweep Shares of the Schwab Tax-Exempt
Money Fund may be compared to that of other mutual funds tracked by mutual fund
rating services, various indices of investment performance, United States
government obligations, bank certificates of deposit, other investments for
which reliable performance data is available and the consumer price index.
 
Because the Sweep Shares of the Schwab Tax-Exempt Money Fund are subject to
different expenses than the Value Advantage Shares, the performance of the two
classes of shares will differ.

TAX-ADVANTAGED RETIREMENT PLANS
--------------------------------------------------------------------------------
THE SCHWAB MONEY MARKET FUND, SCHWAB GOVERNMENT
MONEY FUND AND SCHWAB U.S. TREASURY MONEY FUND MAY
BE SUITABLE INVESTMENTS FOR TAX-ADVANTAGED RETIREMENT PLANS.
--------------------------------------------------------------------------------
 
Schwab offers tax-advantaged retirement plans for which the Schwab Money Market
Fund, Schwab Government Money Fund and Schwab U.S. Treasury Money Fund may be
appropriate investments. It is not recommended that the Schwab Tax-Exempt Money
Fund be used as an investment vehicle for Individual Retirement Accounts or
qualified retirement plans. Schwab's retirement plans allow participants to
defer taxes while helping them build their retirement savings.
 
   
SCHWAB IRA. A retirement plan with a wide choice of investments offering people
with earned income the opportunity to compound earnings on a tax-deferred basis.
Schwab provides the IRA free of Schwab's $29 annual fee for the life of the
account to customers who establish a $10,000 account balance by September 15,
1995.
    
 
   
SCHWAB KEOGH. A tax-advantaged plan for self-employed individuals and their
employees that permits the employer to make annual tax-deductible contributions
of up to $30,000. Schwab Keogh plans are currently charged an annual fee of $45.
    
 
SCHWAB CORPORATE RETIREMENT PLANS. A well designed retirement program can help a
company attract and retain valuable employees. Call your local Schwab office or
800-2 NO-LOAD for more information.
 
GENERAL INFORMATION
 
   
The Schwab Fund Family was organized as a business trust under the laws of
Massachusetts on October 20, 1989 and may issue an unlimited number of shares of
beneficial interest or classes of shares in one or more Series. Currently, the
Schwab Fund Family offers shares of nine Series which may be organized into one
or more classes of shares of beneficial interest. The Board of Trustees may
authorize the issuance of shares of additional Series or classes if it deems it
desirable to do so. Shares of each Series or class have equal, noncumulative
voting rights and equal rights as to dividends, assets, and liquidation of such
Series, except to the extent such voting rights or rights as to dividends,
assets, and liquidation vary among classes of a Series.
    
 
The Schwab Fund Family is not required to hold annual shareholders' meetings. It
will, however, hold special meetings as required or deemed desirable by the
Board of Trustees for such purposes as electing trustees, changing fundamental
policies or approving an investment advisory agreement. In addition, a Trustee
may be elected or removed by shareholders at a special meeting called upon
written request of shareholders owning at least 10% of the outstanding shares of
the Schwab Fund Family. Shareholders will vote by Series and not in the
aggregate (for example, when voting to approve the investment advisory
agreement), except when voting in the aggregate is permitted under
 
                                       20
<PAGE>   21
 
the 1940 Act, such as for the election of Trustees. In addition, holders of the
Sweep Shares of the Schwab Tax-Exempt Money Fund will vote exclusively as a
class on any matter relating solely to the arrangement of the Sweep Shares as a
class and on any matter in which the interests of holders of the Sweep Shares
differ from the interests of the holders of the Value Advantage Shares of the
Fund.
 
SHAREHOLDER GUIDE
----------------------------------------------------------------------------
SCHWAB'S OFFICES ACCEPT ORDERS AND PROVIDE SHAREHOLDER
SERVICE AND INFORMATION.
----------------------------------------------------------------------------
 
   
SHAREHOLDER SERVICE. You may place Fund purchase and redemption orders as well
as request exchanges at any one of over 200 Schwab offices nationwide or by
calling 800-2 NO-LOAD, where trained representatives are available to answer
questions about the Funds and your account. The privilege to initiate
transactions by telephone, as discussed below, is automatically available
through your Schwab account. Each Fund will employ reasonable procedures to
confirm that instructions communicated by telephone are genuine. If these
procedures are not followed, the Fund may be liable for any losses due to
unauthorized or fraudulent instructions. These procedures may include requiring
a form of personal identification prior to acting upon instructions received by
telephone, providing written confirmation of such instructions and tape
recording telephone transactions. Investors should be aware that telephone
redemption may be difficult to implement during periods of drastic economic or
market changes. Shareholders who experience difficulties in purchasing,
redeeming or exchanging shares by telephone can utilize the alternative methods
discussed below to place their orders.
    
 
   
Telephone purchase or redemption orders or exchange requests received prior to
6:00 p.m. (Eastern time) on any Business Day, once they have been verified as to
the caller's identity and account ownership, will be deemed to be received by
Schwab's Mutual Fund Transfer Agency Department prior to the next net asset
value determination. All subsequent telephone redemption orders received prior
to the first net asset value determination on the following day will be deemed
received prior to that day's second net asset value determination.
    
 
HOW TO PURCHASE SHARES
--------------------------------------------------------------------------
YOU MAY PURCHASE SHARES OF THE FUNDS ONLY THROUGH A
SCHWAB ACCOUNT.
--------------------------------------------------------------------------
 
   
You may purchase shares of the Funds exclusively through an account maintained
with Schwab, and payment for shares must be made directly to Schwab. Certain
fees may be charged to Schwab accounts which do not maintain required minimum
balances. (See "Summary of Expenses" for more information.) The Securities
Investor Protection Corporation ("SIPC") will provide account protection, in an
amount up to $500,000, for securities, including Fund shares, which you hold in
a Schwab account. Of course, SIPC account protection does not protect
shareholders from principal fluctuations.
    
 
   
If you already have a Schwab account, you may purchase shares in a Fund as
described below and need not open a new account.
    
 
                                       21
<PAGE>   22
 
   
If you do not presently maintain a Schwab account and wish to establish one,
simply complete a Schwab Account Application, (available by calling 800-2
NO-LOAD, 24 hours a day, or by contacting your local Schwab office) and mail or
deliver it to your local Schwab office. You may also mail the application to
Schwab at 101 Montgomery Street, San Francisco, CA 94104. Corporations and other
organizations should contact their local Schwab office to determine which
additional forms may be necessary to open a Schwab account.
    
 
   
You may deposit funds into your Schwab account by check or wire. All deposit
checks should be made payable to Charles Schwab & Co., Inc. If you would like to
wire funds into your Schwab account, please contact your local Schwab office for
instructions.
    
 
   
You must have funds in your Schwab account in order to purchase Fund shares. If
funds (including those transmitted by wire) are received by Schwab before the
time of the Fund's last daily net asset value calculation (normally 4:00 p.m.
Eastern time), they will be available for investment on that day. If funds
arrive after that time, they will be available for investment the next Business
Day.
    
-----------------------------------------------------------------------------
THE FUNDS MAY BE USED TO "SWEEP" FREE CREDIT BALANCES
IN YOUR SCHWAB BROKERAGE ACCOUNT.

METHODS OF PURCHASING SHARES. Automatic Investment: When opening a Schwab
brokerage account, an investor will be asked to select a SchwabFunds(R) class or
series with sweep privileges as a "primary fund." (If a selection is not made,
the Schwab Money Market Fund will automatically become the investor's primary
fund.) An initial purchase of shares of the primary fund selected will be made
automatically pursuant to the procedures described below when the free credit
balance in the investor's Schwab brokerage account (including deposits, proceeds
of sales of securities, and miscellaneous cash dividends and interest, but not
amounts held by Schwab as collateral for margin obligations to Schwab) exceeds
$1,000 on the last Business Day of the week. Thereafter, free credit balances in
the investor's Schwab brokerage account which, in total, equal or exceed $100 on
the last Business Day of any week will be automatically invested in the primary
fund on the first Business Day of the following week. If an investor's free
credit balance is less than $100, it will not be invested in the primary fund,
but will remain a credit to the investor's Schwab brokerage account. In certain
limited circumstances, free credit balances in certain accounts may be
automatically invested at different times. Upon request, a free credit balance
in a Schwab brokerage account totalling $20,000 or more may be invested in the
appropriate primary fund on the Business Day following receipt by the Transfer
Agent of investor instructions.
 
   
An investor with an existing Schwab brokerage account may add the automatic
investment feature to his or her account by completing the appropriate section
of the Schwab Account Application available at any Schwab office. A shareholder
may change primary funds by calling or writing his or her local Schwab office or
writing Schwab at the above address. Note that the automatic investment feature
is not available for Value Advantage Shares of any fund.

-----------------------------------------------------------------------
SHARES OF THE FUNDS MAY ALSO BE PURCHASED DIRECTLY.
-----------------------------------------------------------------------
 
   
DIRECT PURCHASE: A Schwab account holder may buy shares of a Fund (if it is not
his or her primary fund) by placing an order directly with a Schwab registered
representative. The minimum initial investment for such "secondary fund"
purchase is $1,000, and subsequent investments must be at least $100. The
minimum initial investment for the Value Advantage Shares of the Schwab Tax-
Exempt Money Fund is $25,000 and the minimum account balance for the Value
Advantage Shares is $20,000.
    
-----------------------------------------------------
TWO DISTRIBUTION OPTIONS ARE AVAILABLE.
-----------------------------------------------------
 
   
DISTRIBUTION OPTIONS. The Schwab account standing instructions that you selected
in your Schwab Account Application will determine which of the two distribution
options listed below will apply to you. Fund distributions will be automatically
reinvested, unless the Transfer Agent has received instructions that
distributions be mailed to you as they are paid. Please contact your local
Schwab office if you already have a Schwab account and wish to change your
account standing instructions.
    
 
1. AUTOMATIC REINVESTMENT: For the Schwab Money Market Fund, Schwab Government
   Money Fund and Schwab U.S. Treasury Fund, distributions will be reinvested in
   additional full Shares of the applicable Fund at the net asset value next
   determined after their payable date. For the Schwab Tax-Exempt Money
   Fund--Sweep Shares, all distributions will be reinvested in additional full
   Sweep Shares of the Fund at the net asset value next determined after their
   payable date.
 
2. RECEIVE DIVIDENDS IN CASH: All distributions will be credited to your Schwab
   account as of the payable date. If your account is coded to have dividends
   mailed immediately, checks will normally be mailed the business day after
   distributions are credited.
 
   
For information on how to wire funds from your Schwab account to your bank, see
"Other Important Information--Wire Transfers to Your Bank."
    
 
OTHER PURCHASE INFORMATION. The minimum amounts required for automatic
investment/direct purchase may be reduced or waived on certain occasions. (See
"Purchase and Redemption of Shares" in the Statement of Additional Information.)
Free credit balances in accounts of certain categories of investors, such as
holders of Schwab custodial accounts, may be invested automatically irrespective
of amount. Each Fund reserves the right, in its sole discretion and without
prior notice to shareholders, to withdraw or suspend all or any part of the
offering made by this Prospectus, to reject purchase orders or to change the
minimum investment requirements. All orders to purchase shares of a Fund are
subject to acceptance by the Fund and are not binding until confirmed or
accepted. Schwab will charge a $15 service fee against an investor's Schwab
brokerage account should his or her check be returned because of insufficient or
uncollected funds or a stop payment order.

HOW TO EXCHANGE SHARES
--------------------------------------------------------------------------------
   
SHARES OF THE FUNDS MAY BE EXCHANGED FOR SHARES OF OTHER
FUNDS SPONSORED BY SCHWAB.
    
--------------------------------------------------------------------------------
 
   
The exchange privilege allows you to exchange your SchwabFunds(R) shares for
shares of any other SchwabFunds class or series available to investors in your
state if your purchase meets that fund's eligibility requirements. Thus, you can
conveniently modify your investments if your goals or market conditions change.
An exchange will involve the redemption of shares and the purchase of shares in
another fund. An exchange will be treated as a sale of the shares for federal
income tax purposes. Note that you must meet the minimum initial or subsequent
investment requirements applicable to the shares you wish to receive in an
exchange. Each Fund reserves the right on 60 days' written notice to modify,
limit or terminate the exchange privilege.
    
 
METHODS OF EXCHANGING SHARES.
 
BY PHONE:
 
   
  To exchange between SchwabFunds by telephone, please call your local Schwab
  office during regular business hours or 800-2 NO-LOAD.
    
 
  To properly process your telephone exchange request, we will need the
  following information:
 
   
        - your Schwab account number and your name for verification;
    
   
        - the number of shares to be exchanged and the name of the Fund from
          which you are exchanging shares;
    
        - the name of the fund into which shares are to be exchanged; and
   
        - the distribution option you select.
    
 
BY MAIL:
 
  You may also request an exchange by writing your local Schwab office or Schwab
  at the address listed on the Prospectus cover page.
 
  To properly process your mailed exchange request, we will need a letter from
  you which:
 
   
        - references your Schwab account number;
    
   
        - specifies the Fund from which you would like to exchange shares and
          the number of shares to be exchanged;
    
   
        - indicates the name of the fund into which shares are to be exchanged;
    
   
        - indicates the distribution option you select; and

IN PERSON AT A SCHWAB OFFICE:
 
  You can also place your exchange request in person at your local Schwab
  office.
 
HOW TO REDEEM SHARES
 
   
AUTOMATIC REDEMPTION: Redemptions will be automatically effected by Schwab's
Mutual Fund Transfer Agency Department to satisfy debit balances in an
investor's Schwab account or to provide necessary cash collateral for an
investor's margin obligation to Schwab. Redemptions will also be automatically
effected to settle securities transactions with Schwab if an investor's free
credit balance on the day before settlement is insufficient to settle the
transactions. Each Schwab account will, as of the close of business each
Business Day, be automatically scanned for debits and pending securities
settlements, and, after application of any free credit balances in the account
to such debits, a sufficient number of shares of the primary fund and, to the
extent necessary, any other Schwab Money Fund(s) in the account, will be
redeemed the following Business Day to satisfy any remaining debits.
    
 
   
DIRECT REDEMPTION: Shareholders may also place redemption orders directly by
contacting their local Schwab office by telephone, mail or in person, or by
mailing written instructions to Schwab (at the address listed on the Prospectus
cover page).
    
 
   
Normally a check for a shareholder's redemption proceeds will be available at
the investor's local Schwab office on the Business Day after Schwab's Mutual
Fund Transfer Agency Department receives proper redemption instructions. Checks
will normally be mailed to investors who specifically request such mailing on
the Business Day following share redemption. If you purchased shares by check,
your redemption proceeds may be held in your Schwab brokerage account until your
check clears (which may take up to 15 days). Depending on the type of Schwab
brokerage account you have, your money may earn interest during any holding
period.
    
 
   
Each Fund may suspend redemption rights or postpone payments at times when
trading on the Exchange is restricted, the Exchange is closed for any reason
other than its customary weekend or holiday closings, emergency circumstances as
determined by the SEC exist, or for such other circumstances as the SEC may
permit.
    
 
OTHER IMPORTANT INFORMATION
 
   
MINIMUM BALANCE AND BROKERAGE ACCOUNT REQUIREMENTS. Due to the relatively high
cost of maintaining smaller holdings, each Fund reserves the right to redeem a
shareholder's shares if, as a result of redemptions, their aggregate value drops
below the $100 minimum balance requirement for the Schwab Money Market Fund,
Schwab Government Money Fund, Schwab U.S. Treasury Money Fund and the Sweep
Shares of the Schwab Tax-Exempt Money Fund. A Fund will notify shareholders in
writing 30 days before taking such action to allow them to increase their
holdings to at least the minimum level. Also note that, because they can only be
held in Schwab accounts, Fund shares will be automatically redeemed should the
Schwab account in which they are carried be closed.
    
 
CONSOLIDATED MAILINGS. In an effort to reduce the Funds' mailing costs, the
Funds consolidate shareholder mailings by household. This consolidation means
that a household having multiple accounts with the identical address of record
will receive a single package during each shareholder
 
                                       25
<PAGE>   26
 
mailing. If you do not wish this consolidation to apply to your account(s),
please write to SchwabFunds(R) at 101 Montgomery Street, San Francisco, CA 94104
to that effect.
 
   
WIRE TRANSFERS TO YOUR BANK. If you so instruct your local Schwab office, funds
can be wired from your Schwab account to your bank account. Call your local
Schwab office for additional information. A $15 service fee will be charged
against your Schwab account for each wire sent.
    
 
SCHWAB ONE(R) Account Features. Shareholders who hold shares of the Schwab
Tax-Exempt Money Fund in Schwab One accounts are entitled to redeem shares of
the Fund through debit cards and checks. Investors should contact Schwab if they
are interested in the benefits and requirements of a Schwab One account.

KEY FEATURES OF THE FUND
 
   
MAXIMUM DOUBLE TAX-EXEMPT INCOME AND SAFETY. The Schwab California Tax-Exempt
Money Fund is designed for investors who seek maximum after-tax current income
consistent with liquidity and stability of capital. The Fund invests in high
quality, short-term debt securities, the interest on which is exempt from
federal income and State of California personal income taxes. The Fund attempts
to maintain a stable net asset value of $1.00 per share. (See "Investment
Objective and Policies.")
    
 
AUTOMATIC INVESTMENT/REDEMPTION FEATURE. If you elect, free credit balances in
your Schwab brokerage account (including your Schwab One(R) account) will be
automatically invested or "swept" into the Fund, subject to the terms and
conditions of your brokerage account agreement. Shares will also be sold as
necessary to settle securities transactions, collateralize margin obligations or
cover debit balances. This feature keeps your money working and saves you the
time and trouble of withdrawing and redepositing funds. (See "How to Purchase
Shares" and "How to Redeem Shares.")
 
LIQUIDITY. You can conveniently place orders to redeem your investment in the
Fund at any time. (See "How to Redeem Shares.")
 
   
LOW COST INVESTING. The Fund imposes no sales or transaction fees on purchases
or redemptions of shares of the Fund. (See "Summary of Expenses.") In addition,
the total fund operating expenses of the Sweep Shares of the Fund will not
exceed 0.65% through at least April 30, 1996, as guaranteed by Charles Schwab
Investment Management, Inc. (See "Matching the Fund to Your Investment Needs,"
and "Management of the Fund.")
    
 
   
PROFESSIONAL MANAGEMENT. Charles Schwab Investment Management, Inc. (the
"Investment Manager") currently provides investment management services to the
SchwabFunds(R), a family of 18 mutual funds with over $28 billion in assets as
of July 31, 1995. (See "Management of the Fund.")
    
 
   
SHAREHOLDER SERVICE. Schwab's professional representatives are available
toll-free 24 hours a day to receive your Fund orders. Call your local Schwab
office during business hours or 800-2 NO-LOAD. As a discount broker, Schwab
gives you investment choices and lets you make your own decisions. Schwab has
many services that help you make the most informed investment decisions. (See
"How to Purchase Shares," "How to Exchange Shares" and "How to Redeem Shares.")
    
 
CONVENIENT REPORTING. Customers receive regular Schwab statements that combine
all their mutual fund investment activity on one report.
 
SPECIAL RISK CONSIDERATIONS. An investment in the Fund is subject to certain
risks arising out of the Fund's investments in California Municipal Securities,
municipal leases, participation interests and certain other securities. (See
"Municipal Securities and Investment Techniques.")
 
NATIONWIDE NETWORK OF SCHWAB OFFICES. Schwab has over 200 offices throughout the
U.S. where customers can place purchase and redemption orders.

1 This amount reflects a reduction by the Investment Manager, which is
guaranteed through at least April 30, 1996. If there were no such reduction, the
maximum management fee for the Fund would have been 0.45% of the Fund's average
daily net assets for the fiscal year ended December 31, 1994. (See Management of
the Fund--Fees and Expenses.)
    
 
2 See "Management of the Fund--Fees and Expenses" for information regarding the
differing expenses for the multiple classes of shares of the Fund.
 
   
3 Schwab currently imposes no fees for opening and maintaining a Schwab
brokerage account. Effective October 1, 1995, Schwab will institute a $1,000
minimum equity requirement for brokerage accounts ($500 for custodial accounts).
A quarterly fee of $7.50 will be charged on accounts that fall below the
minimum. This fee, if applicable, will be charged at the end of each quarter and
will be waived if there has been one commissionable trade within the last six
months, or if the shareholder's combined account balances at Schwab total
$10,000 or more. Schwab imposes no fees for opening and maintaining a Schwab
One(R) account with a minimum balance of $5,000. Schwab One accounts with
balances below $5,000 are subject to a monthly fee of $5 if there have been
fewer than two commissionable trades within the last 12 months. Schwab
Individual Retirement Accounts with balances of $10,000 or more by September 15,
1995 are not charged Schwab's $29 annual IRA account fee for the life of the
account. Schwab Keogh plans are currently charged an annual fee of $45. See "How
to Purchase Shares" for information regarding the differing minimum balance and
minimum investment requirements of the multiple classes of shares of the Fund.
    
 
   
4 This amount reflects the guarantee by the Investment Manager and Schwab that,
through at least April 30, 1996, the total fund operating expenses of the Sweep
Shares of the Fund will not exceed 0.65%. Without this guarantee, which was in
effect during the fiscal year ended December 31, 1994, total fund operating
expenses for the Sweep Shares of the Fund would have been 0.94% of the Sweep
Shares' average daily net assets.

EXAMPLE. You would pay the following expenses on a $1,000 investment in the
Sweep Shares of the Fund, assuming (1) a 5% annual return and (2) redemption at
the end of each period:

</TABLE>
 
   
THE PURPOSE OF THE PRECEDING TABLE IS TO ASSIST INVESTORS IN UNDERSTANDING THE
VARIOUS COST AND EXPENSES THAT AN INVESTOR IN THE SWEEP SHARES OF THE FUND WILL
BEAR DIRECTLY OR INDIRECTLY. This example reflects the guarantee by the
Investment Manager and Schwab that, through at least April 30, 1996, the total
fund operating expenses for the Sweep Shares of the Fund will not exceed 0.65%.
ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN. The example assumes a
5% annual rate of return pursuant to requirements of the SEC. THIS HYPOTHETICAL
RATE OF RETURN IS NOT INTENDED TO BE REPRESENTATIVE OF PAST OR FUTURE
PERFORMANCE.

The Investment Manager and Schwab have reduced a portion of their fees and
absorbed certain expenses in order to limit the Fund's ratio of operating
expenses to average net assets. Had these fees and expenses not been reduced and
absorbed, the ratio of expenses to average net assets for the periods ended
December 31, 1994, 1993, 1992, 1991 and 1990 would have been 0.94%, 0.96%,
0.97%, 0.98% and 1.17%*, respectively, and the ratio of net investment income to
average net assets would have been 1.95%, 1.56%, 1.97%, 3.33% and 4.17%*,
respectively.
    
 
Prior to June 6, 1995, the Fund did not offer multiple classes of shares of
beneficial interest. The information contained in this table relates to shares
which were redesignated as Sweep Shares as of June 6, 1995.
 
MATCHING THE FUND TO YOUR INVESTMENT NEEDS
 
The Fund may be appropriate for a variety of investment programs which can be
long-term or short-term in nature. While the Fund is not a substitute for
building an investment portfolio tailored to an individual's investment needs
and risk tolerance, it can be used as a high quality, conveniently liquid money
market investment for your brokerage account cash when it is not fully invested
in other securities. The Fund would not be an appropriate investment for
retirement plans such as IRAs and Keogh plans.
--------------------------------------------------------------------------------
THE FUND MAY BE ESPECIALLY SUITABLE FOR SHORT-TERM INVESTORS.
--------------------------------------------------------------------------------
 
Because the Fund is designed to provide liquidity and stability of capital, as
well as automatic investment of free credit balances, it may be especially
suitable for investors with short-term investment objectives, including those
who are awaiting an opportune time to invest in the equity and/or bond markets.

--------------------------------------------------------------------------------
THE FUND MAY ALSO BE APPROPRIATE FOR LONG-TERM INVESTORS.
--------------------------------------------------------------------------------
 
The Fund may also be appropriate for long-term investors seeking a low-risk
investment alternative which is designed to provide double tax-free income.
 
In addition to the Sweep Shares of the Fund, Schwab also offers Value Advantage
Shares of the Fund, pursuant to a multiple class plan (the "Plan") adopted by
the Board of Trustees of the Schwab Fund Family. Under the Plan, Value Advantage
Shares of the Fund, which are not available through automatic ("sweep")
investment programs, are subject to lower transfer agency expenses than the
Sweep Shares of the Fund. In addition, the minimum investment and minimum
account balance requirements of the Value Advantage Shares of the Fund are
higher than those applicable to the Sweep Shares. See "Management of the
Fund -- Fees and Expenses" and "How to Purchase Shares."
 
For information regarding Value Advantage Shares, call your local Schwab office
or 800-2 NO-LOAD. You may also obtain information about Value Advantage Shares
from your Schwab broker.
 
INVESTMENT OBJECTIVE AND POLICIES
-------------------------------------------------------------------------------
THE FUND SEEKS MAXIMUM CURRENT INCOME CONSISTENT WITH
STABILITY OF CAPITAL THAT IS EXEMPT FROM FEDERAL INCOME
AND STATE OF CALIFORNIA PERSONAL INCOME TAXES.
-------------------------------------------------------------------------------
 
The investment objective of the Fund is maximum current income that is exempt
from federal income and State of California personal income taxes, to the extent
consistent with stability of capital. This investment objective is fundamental,
and cannot be changed without approval by holders of a majority of the Fund's
outstanding voting shares, as defined in the Investment Company Act of 1940 (the
"1940 Act"). The Fund pursues its objective primarily by investing in short-term
high quality municipal obligations, the income from which is exempt from federal
income and California personal income taxes.
 
Under normal market conditions, the Fund attempts to invest 100%, and will
invest at least 80%, of its total assets in debt obligations issued by or on
behalf of California and other states, territories and possessions of the United
States and the District of Columbia and their political subdivisions, agencies
and instrumentalities that generate interest which, in the opinion of bond
counsel, is exempt from federal income tax ("Municipal Securities") and will
invest at least 65% of its total assets in such obligations which also generate
interest which, in the opinion of bond counsel, is exempt from State of
California personal income tax ("California Municipal Securities").
 
Dividends paid to California residents to the extent of interest income received
on California Municipal Securities will be exempt from State of California
personal income taxes provided that at the end of each quarter of its taxable
year at least 50% of the Fund's total assets are invested in California
Municipal Securities and obligations of the U.S. Government, its agencies and
instrumentalities which are by federal law exempt from local income taxes.
 
                                        6
<PAGE>   35
 
-----------------------------------------------------------------
   
THE FUND ONLY INVESTS IN HIGH QUALITY SECURITIES.
    
-----------------------------------------------------------------
 
   
The Fund invests only in Municipal Securities which at the time of purchase: (a)
are rated in one of the two highest rating categories for municipal commercial
paper or short-term municipal securities assigned by Moody's Investors Service
("Moody's"), Standard & Poor's Corporation ("S&P") or any other nationally
recognized statistical rating organization ("NRSRO"); (b) are guaranteed or
insured by the U.S. Government as to the payment of principal and interest; (c)
are fully collateralized by an escrow of U.S. Government securities acceptable
to the Investment Manager; or (d) are unrated by any NRSRO, if they are
determined by the Investment Manager, using guidelines approved by the Board of
Trustees, to be at least equal in quality to one or more of the above referenced
securities. (For a description of the ratings, see "Appendix--Ratings of
Investment Securities" in the Statement of Additional Information.)
    
 
After its purchase by the Fund, a Municipal Security may cease to be rated or
its rating may be reduced below that required for purchase by the Fund. Neither
event would necessarily require the elimination of such an obligation from the
Fund's investment portfolio. However, the obligation generally would be retained
only if such retention was determined by the Board of Trustees to be in the best
interests of the Fund.
 
With the exception of securities issued or guaranteed by the U.S. Government,
its agencies and instrumentalities, the Fund may not:
 
1. Purchase the securities of any issuer if as a result more than 5% of the
   value of the Fund's total assets would be invested in the securities of that
   issuer. However, provided no more than 25% of the value of the Fund's total
   assets are invested in the securities of any one issuer, up to 50% of the
   value of the Fund's total assets may be invested without regard to this 5%
   limitation. For purposes of this limitation, a security is considered to be
   issued by the governmental entity (or entities) whose assets and revenues
   back the security, or, with respect to an industrial revenue bond that is
   backed only by the assets and revenues of a non-governmental user, by such
   non-governmental user. In certain circumstances, the guarantor of a security
   may also be considered to be an issuer in connection with such guarantee.
 
2. Purchase any securities which would cause 25% or more of the value of the
   Fund's total assets at the time of purchase to be invested in the securities
   of issuers conducting their principal business activities in the same
   industry. However, this limitation shall not apply to Municipal Securities.
 
From time to time, as a defensive measure or under abnormal market conditions,
the Fund may invest any or all of its assets in taxable "temporary investments"
which include: obligations of the U.S. Government, its agencies or
instrumentalities; debt securities (other than Municipal Securities) rated in
one of the two highest categories by any NRSRO; commercial paper (other than
Municipal Securities) rated in one of the two highest grades by any NRSRO;
certificates of deposit of domestic banks having capital, surplus, and undivided
profits in excess of $100 million; and any of the foregoing temporary
investments subject to repurchase agreements. While purchases by the Fund of
certain temporary investments could cause it to generate dividends taxable to
shareholders as ordinary
 
                                        7
<PAGE>   36
 
income (see "Distributions And Taxes"), it is the Fund's primary intention to
produce dividends which are not subject to federal income or State of California
personal income taxes.
 
The investment policies set forth above (except for the policy regarding
temporary investments, or as otherwise noted) are fundamental. They, along with
certain investment restrictions adopted by the Fund (see "Investment
Restrictions" in the Statement of Additional Information), cannot be changed
without approval by holders of a majority of the Fund's outstanding voting
shares, as defined in the 1940 Act.
 
MUNICIPAL SECURITIES AND INVESTMENT TECHNIQUES
 
The two principal classifications of Municipal Securities which may be held by
the Fund are "general obligation" securities and "revenue" securities. General
obligation securities are secured by the issuer's pledge of its full faith,
credit and taxing power for the payment of principal and interest. Revenue
securities 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
tax or other specific revenue source such as the user of the facility being
financed. Revenue securities may include private activity bonds (and industrial
development bonds). Such bonds may be issued by or on behalf of public
authorities to finance various privately operated facilities, and are not
payable from the unrestricted revenues of the issuer. As a result, the credit
quality of private activity bonds is frequently related directly to the credit
standing of private corporations or other entities. From time to time, the Fund
may invest more than 25% of its total assets in industrial development and
private activity bonds.
 
The Fund's portfolio may also include "moral obligation" securities, which are
normally issued by special purpose public authorities. If the issuer of moral
obligation securities is unable to meet its debt service obligations from
current revenues, it may draw on a reserve fund, the restoration of which is a
moral commitment but not a legal obligation of the state or municipality which
created the issuer.
 
Municipal Securities purchased by the Fund may include variable rate demand
instruments issued by industrial development authorities and other government
entities. In the event variable rate demand instruments which the Fund can
purchase are not rated by credit rating agencies, such instruments must be
determined by the Investment Manager, using guidelines approved by the Board of
Trustees, to be of comparable quality at the time of purchase to rated
instruments which the Fund can purchase. In some cases, the Fund may require
that the issuer's obligation to pay the principal of the note be backed by an
unconditional bank letter or line of credit, guarantee or commitment to lend.
Although there may be no active secondary market with respect to a particular
variable rate demand instrument purchased by the Fund, the Fund may (at any time
or during specified periods not exceeding one year, depending upon the
instrument involved) demand payment in full of the principal of the instrument
and may resell the instrument to a third party. The absence of such an active
secondary market, however, could make it difficult for the Fund to dispose of a
variable rate demand instrument in the event the issuer defaulted on its payment
obligation or during periods that the Fund is not entitled to exercise its
demand rights, and the Fund could, for this or other reasons, suffer a loss with
respect to such instruments. To the extent that the absence of an active
secondary market for such securities causes them to be "illiquid," such
securities will be subject to the Fund's restrictions on acquiring and holding
illiquid securities.
 
                                        8
<PAGE>   37
 
Participation interests in Municipal Securities with fixed, floating or variable
rates of interest may be purchased by the Fund from financial institutions. The
buyer of a participation interest receives an undivided interest in the
securities underlying the instrument. The Fund will only purchase a
participation interest if: (a) the Municipal Securities subject to it mature in
one year or less or the instrument includes a right to demand payment, usually
within seven days, from the Seller, (b) the instrument meets the Fund's
previously described quality standards for Municipal Securities, and (c) the
instrument is issued with an opinion of counsel or is the subject of a ruling of
the Internal Revenue Service, stating that the interest earned on the
participation interest is exempt from federal income tax.
 
The Fund may invest in municipal leases, which are obligations issued by state
and local governments or authorities to finance the acquisition of equipment and
facilities. These obligations may take the form of a lease, an installment
purchase contract, a conditional sales contract, or a participation interest in
any of the above. Investments in municipal leases may be considered to be
illiquid. The Fund will limit its investment in municipal leases to no more than
25% of its total assets (no more than 10% of which may be illiquid municipal
leases). Municipal leases are subject to "nonappropriation risk," which is the
risk that the municipality may terminate the lease in the event that the
municipality's appropriating body does not allocate the funds necessary to make
lease payments. In such circumstances, the lessor is typically entitled to
repossess the property. The private sector value of the property is, however,
generally less than the value of the property to the municipality. The
Investment Manager, pursuant to guidelines established by the Board of Trustees,
is responsible for determining the credit quality of unrated municipal leases,
on an ongoing basis, including an assessment of the likelihood of whether the
lease will be terminated.
 
   
The Fund may also invest up to 25% of its assets in synthetic variable or
floating rate municipal securities. These securities generally comprise the
following elements in a trust: (i) a fixed-rate municipal bond (of any
duration); (ii) a right to put the bond at par value on 7-days notice or after a
specific interval of time depending on the terms of the synthetic security; and
(iii) a contractual agreement pursuant to which the investing Fund and the
issuer determine the lowest rate that would permit the bond to be remarketed at
par, taking into account the put right. The trustee of the trust is generally a
bank trust department.
    
 
These securities may include tender option bond trust receipts, in which a
fixed-rate municipal bond (or group of bonds) is placed into a trust from which
two classes of trust receipts are issued, which represent proportionate
interests in the underlying bond(s). Interest payments are made on the bond(s)
based upon a predetermined rate. Under certain circumstances, the holder of a
trust receipt may also participate in any gain or loss on the sale of such
bond(s). Tender option bond trust receipts are considered to be Municipal
Securities for purposes of the Fund's policy to invest at least 80% of its total
assets in Municipal Securities. Tender option bond trust receipts generally are
structured as private placements and, accordingly, may be deemed to be
restricted securities for purposes of the Fund's investment limitations.
 
   
The Fund may purchase securities on a "when-issued" or "delayed delivery" basis.
When-issued or delayed delivery securities are securities purchased for future
delivery at a stated price and yield. The

 
                                        9
<PAGE>   38
 
Fund will generally not pay for such securities or start earning interest on
them until they are received. Securities purchased on a when-issued or delayed
delivery basis are recorded as an asset and are subject to changes in value
based upon changes in the general level of interest rates. The Fund will not
invest more than 25% of its assets in when-issued or delayed delivery
securities, does not intend to purchase such securities for speculative purposes
and will make commitments to purchase securities on a when-issued or delayed
delivery basis with the intention of actually acquiring the securities. However,
the Fund reserves the right to sell acquired when-issued or delayed delivery
securities before their settlement dates if deemed advisable.
    
 
The Fund may also acquire "stand-by commitments" with respect to Municipal
Securities held in its portfolio. Under a stand-by commitment, a dealer agrees
to purchase at the Fund's option specified Municipal Securities at a price equal
to their amortized cost value plus accrued interest. The Fund will acquire
stand-by commitments solely to facilitate portfolio liquidity and does not
intend to exercise its rights thereunder solely for trading purposes.
 
The Fund may engage in "repurchase agreements." In entering into a repurchase
agreement, the Fund acquires ownership of a security from a broker-dealer or
bank that agrees to repurchase the security at a mutually agreed upon time and
price (which price is higher than the purchase price), thereby determining the
yield during the Fund's holding period. Repurchase agreements with broker-dealer
firms will be limited to obligations of the U.S. Government, its agencies or
instrumentalities. Maturity of the securities subject to repurchase may exceed
one year.
 
   
As a matter of fundamental policy, the Fund may borrow money for temporary
purposes, but not for the purpose of purchasing investments, in an amount up to
one-third of the value of the Fund's total assets and may pledge up to 10% of
the Fund's net assets to secure borrowings. The Fund will not purchase illiquid
securities, including repurchase agreements maturing in more than 7-days, if, as
a result thereof, more than 10% of the Fund's net assets valued at the time of
the transaction would be invested in such securities.
    
 
Opinions relating to the validity of Municipal Securities and to the exemption
of interest thereon from federal income tax (and, with respect to California
Municipal Securities, to the exemption of interest thereon from State of
California personal income taxes) are rendered by bond counsel to the respective
issuers at the time of issuance. The Fund and the Investment Manager will not
review the proceedings relating to the issuance of Municipal Securities or the
bases for such opinions.
 
SPECIAL RISK CONSIDERATIONS. The Fund intends to follow the diversification
standards set forth in the 1940 Act, except to the extent that, in the
Investment Manager's judgment, non-diversification is appropriate to maximize
the percentage of the Fund's assets that are California Municipal Securities.
The investment return on a non-diversified portfolio typically is dependent upon
the performance of a smaller number of issuers relative to the number of issuers
held in a diversified portfolio. In the event of changes in the financial
condition or in the market's assessment of certain issuers, the Fund's policy of
acquiring large positions in the obligations of a relatively small number of
issuers may affect the value of the Fund's portfolio to a greater extent than
that of a diversified portfolio.
 
                                       10
<PAGE>   39
 
Although the Fund does not presently intend to do so on a regular basis, it may
invest more than 25% of its assets in Municipal Securities the interest on which
is paid solely from revenues on similar projects if such investment is deemed
necessary or appropriate by the Investment Manager. To the extent that the
Fund's assets are concentrated in Municipal Securities payable from revenues on
similar projects, the Fund will be subject to the particular risks presented by
such projects to a greater extent than it would be if the Fund's assets were not
so concentrated.
 
Certain California constitutional amendments, legislative measures, executive
orders, administrative regulations and voter initiatives could result in adverse
consequences affecting California Municipal Securities. For example, in recent
years "Proposition 13" and similar California constitutional and statutory
amendments and initiatives have restricted the ability of California taxing
entities to increase real property tax revenues. Other initiative measures
approved by California voters, through limiting various other taxes, have
resulted in a substantial reduction in state revenues. Decreased state revenues
may result in reductions in allocations of state revenues to local governments.
It is not possible to determine the impact of these initiatives on the ability
of California issuers to pay interest or repay principal on their obligations.
There is no assurance that any California issuer will make full or timely
payments of principal and interest or remain solvent. For example, in December
1994, Orange County filed for bankruptcy. In addition, from time to time,
federal legislative proposals have threatened the tax-exempt status or use of
municipal securities. (An expanded discussion of the risks associated with
municipal securities and California issuers is contained in the Statement of
Additional Information.)
 
Participation interests in Municipal Securities and other derivative securities
eligible for purchase by the Fund involve special risks, including a risk that
the Internal Revenue Service may characterize some or all of the interest paid
on such securities to the Fund as taxable. There is also an increased risk, most
typically associated with "municipal lease" obligations, that a municipality
will not appropriate the funds necessary to make the scheduled payments on, or
may seek to cancel or otherwise avoid its obligations under, the lease that
supports the security owned by the Fund.
 
   
MANAGEMENT OF THE FUND
    
 
   
Responsibility for overall management of the Fund rests with the trustees and
officers of the Schwab Fund Family. Professional investment management for the
Fund is provided by the Investment Manager, Charles Schwab Investment
Management, Inc., 101 Montgomery Street, San Francisco, CA 94104. The Investment
Manager provides a continuous investment program, including general investment
and economic advice regarding the Fund's investment strategies, manages the
Fund's investment portfolio and performs expense management, accounting and
recordkeeping, and other services necessary to the operation of the Fund and the
Schwab Fund Family. The Investment Manager, formed in 1989, is a wholly owned
subsidiary of The Charles Schwab Corporation and is the investment adviser and
administrator of the SchwabFunds(R) mutual funds. As of July 31, 1995, the
Schwab Funds had aggregate net assets in excess of $28 billion.
    
 
Charles Schwab & Co., Inc. ("Schwab" or the "Transfer Agent"), 101 Montgomery
Street, San Francisco, CA 94104, serves as shareholder services agent and
transfer agent for the Fund. Schwab provides information and services to
shareholders, which include reporting share ownership, sales and
 
                                       11
<PAGE>   40
 
dividend activity (and associated tax consequences), responding to daily
inquiries, effecting the transfer of Fund shares and facilitating effective cash
management of shareholders' Schwab account balances. It furnishes such office
space and equipment, telephone facilities, personnel and informational
literature distribution as is necessary or appropriate in providing shareholder
and transfer agency information and services. Schwab is also the Fund's
distributor, but receives no compensation for its services as such.
 
   
Schwab was established in 1971 and is one of America's largest discount brokers.
The firm provides low-cost securities brokerage and related financial services
to over 2.5 million active customer accounts and has over 200 offices. Schwab
also offers convenient access to financial information services and provides
products and services that help investors make investment decisions. Schwab is a
wholly-owned subsidiary of The Charles Schwab Corporation. Charles R. Schwab is
the founder, Chairman and Chief Executive Officer and a director of The Charles
Schwab Corporation and, as of July 31, 1995, the beneficial owner of
approximately 20.5% of the outstanding shares of that corporation. Mr. Schwab
may be deemed to be a controlling person of Schwab and the Investment Manager.
    
 
   
FEES AND EXPENSES. Pursuant to its Investment Advisory and Administration
Agreement with the Schwab Fund Family, the Investment Manager receives from the
Fund a graduated annual fee, payable monthly, of 0.46% of the Fund's average
daily net assets not in excess of $1 billion, 0.41% of such net assets over $1
billion but not in excess of $2 billion and 0.40% of such net assets over $2
billion. The Investment Manager may reduce its management fee from time to time
in the future. Fee reductions lower the Fund's expenses and thus increase the
total return it provides shareholders. At least through April 30, 1996, the
Investment Manager guarantees that the management fee will not exceed 0.19% of
the Fund's average daily net assets. In addition, the Investment Manager and
Schwab guarantee that total fund operating expenses will not exceed 0.65% of the
average daily net assets of the Sweep Shares. The effect of these guarantees is
to maintain or lower the expenses of the Sweep Shares of the Fund and thus
maintain or increase total return to shareholders. For the fiscal year ended
December 31, 1994, the Fund paid investment management fees of 0.18% of its
average daily net assets and paid total expenses of 0.64% of its average daily
net assets.
    
 
For the transfer agency services provided, the Transfer Agent receives an annual
fee, payable monthly, of 0.25% of the average daily net assets of the Sweep
Shares of the Fund. In addition, for shareholder services provided, Schwab
receives an annual fee, payable monthly, of 0.20% of the average daily net
assets of the Sweep Shares of the Fund. For the Value Advantage Shares, the
Transfer Agent receives an annual fee of 0.05% of the average daily net assets
of that class' shares of beneficial interest. PNC Bank is the Fund's Custodian.
 
The Schwab Fund Family pays the expenses of its operations. These expenses are
generally allocated among the Schwab Fund Family's investment portfolios
("Series") on the basis of relative net assets at the time of allocation.
However, expenses directly attributable to a particular Series or class of a
Series are charged to that Series or class, respectively. The differing expenses
applicable to the Sweep Shares and the Value Advantage Shares will cause the
performance of the two classes of shares of the Fund to differ.

DISTRIBUTIONS AND TAXES
--------------------------------------------------------------------------------
THE FUND DECLARES DAILY DIVIDENDS WHICH ARE PAID MONTHLY.
--------------------------------------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS. On each day that the net asset value per
share of the Fund is determined ("Business Day"), the Fund's net investment
income will be declared as of the close of trading on the New York Stock
Exchange (the "Exchange") (generally 4:00 p.m. Eastern time) as a dividend to
shareholders already of record at the previous net asset value calculation.
Dividends are normally paid (and, where applicable, reinvested) on the 15th of
each month, if a Business Day, otherwise on the next Business Day.
 
   
TAX INFORMATION. The Fund has elected to be treated as a regulated investment
company under the Internal Revenue Code of 1986, as amended (the "Code"),
qualified as such, and intends to continue to so qualify. In order to so
qualify, the Fund will distribute on a current basis substantially all of its
investment company taxable income, its net exempt-interest income and its net
capital gains (if any), and will meet certain other requirements. Such
qualification relieves the Fund of liability for federal and California income
taxes to the extent the Fund's earnings are distributed.
    
 
   
FEDERAL INCOME TAXES: Dividends derived from exempt-interest on state and local
obligations and designated by the Fund as "exempt-interest dividends" may be
treated by the Fund's shareholders as items of interest excludable from their
federal gross income. A shareholder should consult his or her own tax adviser
with respect to whether exempt-interest dividends would be excludable from gross
income if the shareholder were treated as a "substantial user" of facilities
financed by an obligation held by the Fund or a "related person" to such user
under the Code. Any loss on the sale or exchange of any share held for six
months or less will be disallowed to the extent of the amount of the exempt-
interest dividend received with respect to such share. The U.S. Treasury
Department is authorized to issue regulations reducing the period to not less
than 31 days for certain regulated investment companies, but no such regulations
have been issued as of the date of this Prospectus. To the extent dividends paid
to shareholders are derived from taxable interest or short-term or long-term
capital gains, such dividends will be subject to federal income tax whether paid
in the form of cash or additional shares. Fund dividends derived from interest
on U.S. Treasury and agency obligations are subject to federal income tax.
    
 
The Fund may at times purchase Municipal Securities or California Municipal
Securities at a discount from the price at which they were initially issued. For
federal income tax purposes, some or all of this market discount will be
included in the Fund's ordinary income and will be taxable to shareholders as
such when it is distributed to them.
 
If the Fund holds certain "private activity bonds" ("industrial development
bonds" under prior law), dividends derived from interest on such obligations
will be classified as an item of tax preference which could subject certain
shareholders to federal alternative minimum tax liability. Corporate
shareholders must also take all exempt-interest dividends into account in
determining "adjusted current earnings" for purposes of calculating their
alternative minimum tax.
 
                                       13
<PAGE>   42
 
Private activity bonds and industrial development bonds generally are bonds
issued by or on behalf of public authorities to obtain funds to provide certain
privately owned or operated facilities. Private activity bonds and industrial
development bonds also are generally limited obligation (or revenue) securities,
which means that they are payable only from the revenues derived from a
particular facility or class of facilities, or, in some cases, from some other
specific revenue source. (See "Municipal Securities" in the Statement of
Additional Information.)
 
Reinvested distributions will be taxable as if they had been received by
shareholders in cash. It is not expected that any portion of the dividends paid
by the Fund will be eligible for the corporate dividends received deduction.
Shareholders should note that all exempt-interest dividends will be taken into
account in determining the taxability of Social Security benefits or Railroad
Retirement Act benefits. (See "Distributions and Taxes" in the Statement of
Additional Information.)
 
CALIFORNIA INCOME TAXES: Dividends paid by the Fund to non-corporate
shareholders and derived from interest on California Municipal Securities or
federal obligations are also exempt from State of California personal income
tax. For this purpose, federal obligations are obligations the interest on which
is excludable from gross income for state income tax purposes under the
Constitution or laws of the United States. However, dividends paid to
shareholders that are corporations subject to California franchise tax or
corporate income tax will be taxed as ordinary income to such shareholders,
notwithstanding that all or a portion of such dividends are exempt from State of
California personal income tax. Moreover, to the extent that the Fund's
dividends are derived from interest on debt obligations other than California
Municipal Securities or federal obligations, such dividends will be subject to
State of California personal income tax, even though such dividends may be
exempt for federal income tax purposes.
 
Except as noted with respect to State of California personal income tax,
distributions of net investment income may be taxable to investors under state
or local law as dividend income even though all or a portion of such
distributions may be derived from interest on tax-exempt obligations which, if
realized directly, would be exempt from such income taxes. In addition, to the
extent, if any, that dividends paid to shareholders are derived from taxable
interest or from long-term or short-term capital gains, such dividends will not
be exempt from State of California personal income tax whether received in cash
or reinvested in shares.
 
   
Records of dividends and other distributions, purchases and redemptions will be
reflected on shareholders' regular Schwab statements. The Fund will notify
shareholders at least annually as to the federal income and State of California
personal income tax consequences of distributions made each year.
    
 
The foregoing is only a brief summary of some of the federal and State of
California income tax considerations affecting the Fund and its shareholders.
Accordingly, potential investors should consult their tax advisers with specific
reference to their own tax situations.

SHARE PRICE CALCULATION
------------------------------------------------------------------
THERE ARE NO SALES CHARGES OR TRANSACTION FEES TO
PURCHASE OR REDEEM SHARES OF THE FUND.
------------------------------------------------------------------
 
   
The price of a Sweep Share of the Fund on any given day is its "net asset value"
or "NAV." This figure is computed by dividing total Fund assets allocable to
that class, less any liabilities allocable to the class, by the number of shares
of the class outstanding. The net asset value per share of the Sweep Shares of
the Fund is determined on each day both the Federal Reserve Bank of New York and
the Exchange are open for business, first at 10:00 a.m. (Eastern time), then
again as of the close of normal trading on the Exchange (generally 4:00 p.m.
Eastern time). Purchase or redemption orders and exchange requests will be
executed at the net asset value next determined after receipt by Schwab's Mutual
Fund Transfer Agency Department. While the Fund attempts to maintain a net asset
value at a constant $1.00 per share, Fund shares are not insured against a
reduction in net asset value.
    
 
   
The Fund values its portfolio securities at amortized cost, which means that
they are valued at their acquisition cost (as adjusted for amortization of
premium or discount) rather than at current market value. Calculations are made
to compare the value of the Fund's investments using the amortized cost method
with market values. Except as described below, market valuations are obtained by
using actual quotations provided by third-party pricing services, market makers,
estimates of market value, or values obtained from yield data relating to
classes of money market instruments published by reputable sources at the mean
between the bid and asked prices for the instruments. If a deviation of 1/2 of
1% or more were to occur between the net asset value per share of the Sweep
Shares of the Fund calculated by reference to market values and the $1.00 per
share amortized cost value of the Sweep Shares of the Fund, or if there were any
other deviation which the Board of Trustees believed would result in a material
dilution to shareholders or purchasers, the Board of Trustees would promptly
consider what action, if any, should be initiated.
    
 
   
HOW THE FUND SHOWS PERFORMANCE
    
 
   
From time to time the Fund may advertise the yield, effective yield, taxable
equivalent yield and taxable equivalent effective yield of the Sweep Shares.
Performance figures are based upon historical results and are not intended to
indicate future performance.
    
 
The yield of the Sweep Shares of the Fund refers to the income generated by a
hypothetical investment in the Sweep Shares of the Fund over a specific 7-day
period. This income is then annualized, which means that the income generated
during the 7-day period is assumed to be generated each week over an annual
period and is shown as a percentage of the hypothetical investment.
 
Effective yield is calculated similarly, but the income earned by the investment
is assumed to be compounded weekly when annualized. The effective yield will be
slightly higher than the yield due to this compounding effect.
 
   
Taxable equivalent yield is the yield that a taxable investment must generate in
order to equal (after applicable taxes are deducted) the Sweep Share's yield for
an investor in stated federal income and

 
                                       15
<PAGE>   44
 

State of California tax brackets (normally assumed to be the applicable maximum
tax rate). Taxable equivalent yield is based upon, and will be higher than, the
portion of the Sweep Share's yield that is tax-exempt. (See "Yield" in the
Statement of Additional Information.)
    
 
   
The taxable equivalent effective yield is computed in the same manner as is the
taxable equivalent yield, except that the effective yield is substituted for
yield in the calculation.
    
 
The performance of the Sweep Shares of the Fund may be compared to that of other
mutual funds tracked by mutual fund rating services, various indices of
investment performance, United States government obligations, bank certificates
of deposit, other investments for which reliable performance data is available
and the consumer price index.
 
Because the Sweep Shares of the Fund are subject to different expenses than the
Value Advantage Shares of the Fund, the performance of the two classes of shares
will differ.
 
Additional performance information about the Sweep Shares of the Fund is
available in the Fund's Annual Report, which is sent to all shareholders. To
request a free copy, call your local Schwab office at 800-2 NO-LOAD.
 
GENERAL INFORMATION
 
   
The Schwab Fund Family was organized as a business trust under the laws of
Massachusetts on October 20, 1989 and may issue an unlimited number of shares of
beneficial interest or classes of shares in one or more Series. Currently, the
Schwab Fund Family offers shares of nine Series which may be organized into one
or more classes of shares of beneficial interest. The Board of Trustees may
authorize the issuance of shares of additional Series or classes if it deems it
desirable to do so. Shares of each Series or class have equal, noncumulative
voting rights, and equal rights as to dividends, assets, and liquidation of such
Series, except to the extent such voting rights or rights as to dividends,
assets and liquidation vary among classes of a Series. The Schwab California
Tax-Exempt Money Fund was formerly known as the Schwab California Tax-Free Money
Fund.
    
 
The Schwab Fund Family is not required to hold annual shareholders' meetings. It
will, however, hold special meetings as required or deemed desirable by the
Board of Trustees for such purposes as electing trustees, changing fundamental
policies, or approving an investment advisory or sub-advisory agreement. In
addition, a Trustee may be elected or removed by shareholders at a special
meeting called upon written request of shareholders owning at least 10% of the
outstanding shares of the Schwab Fund Family. Shareholders will vote by Series
and not in the aggregate (for example, when voting to approve the investment
advisory agreement), except when voting in the aggregate is permitted under the
1940 Act, such as for the election of Trustees. In addition, holders of the
Sweep Shares will vote exclusively as a class on any matter relating solely to
the Sweep Shares' arrangement as a class and on any matter in which the
interests of the holders of the Sweep Shares differ from the interests of the
holders of Value Advantage Shares.

SHAREHOLDER GUIDE
-----------------------------------------------------------
SCHWAB'S OFFICES ACCEPT ORDERS AND PROVIDE
SHAREHOLDER SERVICE AND INFORMATION.
-----------------------------------------------------------
 
   
SHAREHOLDER SERVICE. You may place Fund purchase and redemption orders as well
as request exchanges at any one of over 200 Schwab offices nationwide or by
calling 800-2 NO-LOAD, where trained representatives are available to answer
questions about the Fund and your account. The privilege to initiate
transactions by telephone, as discussed below, is automatically available
through your Schwab account. The Fund will employ reasonable procedures to
confirm that instructions communicated by telephone are genuine. If these
procedures are not followed, the Fund may be liable for any losses due to
unauthorized or fraudulent instructions. These procedures may include requiring
a form of personal identification prior to acting upon instructions received by
telephone, providing written confirmation of such instructions and tape
recording telephone transactions. Investors should be aware that telephone
redemption may be difficult to implement during periods of drastic economic or
market changes. Shareholders who experience difficulties in purchasing,
redeeming, or exchanging shares by telephone can utilize the alternative methods
discussed below to place their orders.
    
 
   
Telephone purchase or redemption orders and exchange requests received prior to
6:00 p.m. (Eastern time) on any Business Day, once they have been verified as to
the caller's identity and account ownership, will be deemed to be received by
Schwab's Mutual Fund Transfer Agency Department prior to the next net asset
value determination. All subsequent telephone redemption orders received prior
to the first net asset value determination on the following day will be deemed
received prior to that day's second net asset value determination.
    
 
HOW TO PURCHASE SHARES
-------------------------------------------------------------------------
YOU MAY PURCHASE SHARES OF THE FUND ONLY THROUGH A
SCHWAB ACCOUNT.
-------------------------------------------------------------------------
 
Shares of the Fund are designed for sale to California residents only.
 
   
You may purchase shares of the Fund exclusively through an account maintained
with Schwab, and payment for shares must be made directly to Schwab. Certain
fees may be charged to Schwab accounts which do not maintain required minimum
balances. (See "Summary of Expenses" for more information.) The Securities
Investor Protection Corporation ("SIPC") will provide account protection, in an
amount up to $500,000, for securities, including Fund shares, which you hold in
a Schwab account. Of course, SIPC account protection does not protect
shareholders from principal fluctuations.
    
 
   
If you already have a Schwab account, you may purchase shares in the Fund as
described below and need not open a new account.
    
 
   
If you do not presently maintain a Schwab account and wish to establish one,
simply complete a Schwab Account Application (available by calling
800-2-NO-LOAD, 24 hours a day, or by contacting

 
                                       17
<PAGE>   46
 

your local Schwab office) and mail or deliver it to your local Schwab office.
You may also mail the application to Schwab at 101 Montgomery Street, San
Francisco, California 94104. Corporations and other organizations should contact
their local Schwab office to determine which additional forms may be necessary
to open a Schwab account.
    
 
   
You may deposit funds into your Schwab account by check or wire. All deposit
checks should be made payable to Charles Schwab & Co., Inc. If you would like to
wire funds into your Schwab account, please contact your local Schwab office for
instructions.
    
 
   
You must have funds in your Schwab account in order to purchase Fund shares. If
funds (including those transmitted by wire) are received by Schwab before the
time of the Fund's last daily net asset value calculation (normally 4:00 p.m.
Eastern time), they will be available for investment on that day. If funds
arrive after that time, they will be available for investment the next Business
Day.
    
---------------------------------------------------------------------------
THE FUND MAY BE USED TO "SWEEP" FREE CREDIT BALANCES
IN YOUR SCHWAB BROKERAGE ACCOUNT.
---------------------------------------------------------------------------
 
   
METHODS OF PURCHASING SHARES. AUTOMATIC INVESTMENT: When opening a Schwab
brokerage account, an investor will be asked to select a SchwabFunds(R) class or
series with sweep privileges as a "primary fund." (If a selection is not made,
the Schwab Money Market Fund will automatically become then investor's primary
fund.) An initial purchase of shares of the primary fund selected will be made
automatically pursuant to the procedures described below when the free credit
balance in the investor's Schwab brokerage account (including deposits, proceeds
of sales of securities, and miscellaneous cash dividends and interest, but not
amounts held by Schwab as collateral for margin obligations to Schwab) exceeds
$1,000 on the last Business Day of the week. Thereafter, free credit balances in
the investor's Schwab brokerage account which, in total, equal or exceed $100 on
the last Business Day of any week will be automatically invested in the primary
fund on the first Business Day of the following week. If an investor's free
credit balance is less than $100, it will not be invested in the primary fund,
but will remain a credit to the investor's Schwab brokerage account. In certain
limited circumstances, free credit balances in certain accounts may be
automatically invested at different times. Upon request, a free credit balance
in a Schwab brokerage account totalling $20,000 or more may be invested in the
appropriate primary fund on the Business Day following receipt by the Transfer
Agent of investor instructions.
    
 
   
An investor with an existing Schwab brokerage account may add the automatic
investment feature to his or her account by completing the appropriate section
of the Schwab Account Application available at any Schwab office. A shareholder
may change primary funds by calling or writing his or her local Schwab office or
writing Schwab at the above address. Note that the automatic investment feature
is not available for Value Advantage Shares of any fund.
    
----------------------------------------------------------------------
SHARES OF THE FUND MAY ALSO BE PURCHASED DIRECTLY.
----------------------------------------------------------------------
 
   
DIRECT PURCHASE: A Schwab account holder may buy shares of the Fund (if it is
not his or her primary fund) by placing an order directly with a Schwab
registered representative. The minimum initial investment for such "secondary
fund" purchase is $1,000, and subsequent investments must be at

 
                                       18
<PAGE>   47
 
least $100. The minimum initial investment for the Value Advantage Shares is
$25,000 and the minimum account balance for the Value Advantage Shares is
$20,000.
    

-----------------------------------------------------
TWO DISTRIBUTION OPTIONS ARE AVAILABLE.
-----------------------------------------------------
 
   
DISTRIBUTION OPTIONS. The Schwab account standing instructions that you selected
in your Schwab Brokerage Account Application will determine which of the two
distribution options listed below will apply to you. Fund distributions will be
automatically reinvested, unless the Transfer Agent has received instructions
that distributions be mailed to you as they are paid. Please contact your local
Schwab office if you already have a Schwab account and wish to change your
account standing instructions.
    
 
1. AUTOMATIC REINVESTMENT: All distributions will be reinvested in additional
   full Sweep Shares of the Fund at the net asset value next determined after
   their payable date.
 
2. RECEIVE DIVIDENDS BY MAIL: All distributions will be credited to your Schwab
   account as of the payable date. If your account is coded to have dividends
   mailed immediately, checks will normally be mailed the Business Day after
   distributions are credited.
 
   
For information on how to wire funds from your Schwab account to your bank, see
"Other Important Information--Wire Transfers to Your Bank."
    
 
   
OTHER PURCHASE INFORMATION. The minimum amounts required for automatic
investment/direct purchase may be reduced or waived on certain occasions. (See
"Purchase and Redemption of Shares" in the Statement of Additional Information.)
Free credit balances in accounts of certain categories of investors, such as
holders of Schwab custodial accounts, may be invested automatically irrespective
of amount. The Fund reserves the right, in its sole discretion and without prior
notice to shareholders, to withdraw or suspend all or any part of the offering
made by this Prospectus, to reject purchase orders or to change the minimum
investment requirements. All orders to purchase shares of the Fund are subject
to acceptance by the Fund and are not binding until confirmed or accepted.
Schwab will charge a $15 service fee against an investor's Schwab account should
his or her check be returned because of insufficient or uncollected funds or a
stop payment order.
    
 
HOW TO EXCHANGE SHARES
----------------------------------------------------------------------
SHARES OF THE FUND MAY BE EXCHANGED FOR SHARES OF
   
OTHER FUNDS SPONSORED BY SCHWAB.
    
----------------------------------------------------------------------
 
   
The exchange privilege allows you to exchange your SchwabFunds(R) shares for
shares of any other SchwabFunds class or series available to investors in your
state if your purchase meets that fund's eligibility requirements. Thus, you can
conveniently modify your investments if your goals or market conditions change.
An exchange will involve the redemption of shares and the purchase of shares in
another fund. An exchange will be treated as a sale of the shares for federal
income tax purposes. Note that you must meet the minimum initial or subsequent
investment requirements applicable to the shares you wish to receive in an
exchange. The Fund reserves the right on 60 days' written notice to modify,
limit or terminate the exchange privilege.
    
 
                                       19
<PAGE>   48
 
METHODS OF EXCHANGING SHARES.
 
BY PHONE:
 
   
  To exchange between any of the SchwabFunds(R) by telephone, please call your
  local Schwab office during regular business hours or 800-2 NO-LOAD.
    
 
  To properly process your telephone exchange request, we will need the
  following information:
 
   
        - your Schwab account number and your name for verification;
    
   
        - the number of shares to be exchanged from the Fund;
    
   
        - the name of the fund into which shares are to be exchanged; and
    
   
        - the distribution option you select.
    
 
BY MAIL:
 
  You may also request an exchange by writing your local Schwab office or Schwab
  at the address listed on the Prospectus cover page.
 
  To properly process your mailed exchange request, we will need a letter from
  you which:
 
   
        - references your Schwab account number;
    
   
        - specifies that you would like to exchange shares from the Fund and the
          number of shares to be exchanged;
    
   
        - indicates the name of the fund into which shares are to be exchanged;
    
   
        - indicates the distribution option you select; and
    
        - is signed by at least one of the registered Schwab account holders, in
          the exact form specified in the account.
 
IN PERSON AT A SCHWAB OFFICE:
 
  You can also place your exchange request in person at your local Schwab
  office.
 
HOW TO REDEEM SHARES
 
   
AUTOMATIC REDEMPTION: Redemptions will be automatically effected by Schwab's
Mutual Fund Transfer Agency Department to satisfy debit balances in an
investor's Schwab account or to provide necessary cash collateral for an
investor's margin obligation to Schwab. Redemptions will also be automatically
effected to settle securities transactions with Schwab if an investor's free
credit balance on the day before settlement is insufficient to settle the
transactions. Each Schwab account will, as of the close of business each
Business Day, be automatically scanned for debits and pending securities
settlements, and, after application of any free credit balances in the account
to such debits, a sufficient number of shares of the primary fund and, to the
extent necessary, any other Schwab Money Fund(s) in the account, will be
redeemed the following Business Day to satisfy any remaining debits.
    
 
   
DIRECT REDEMPTION: Shareholders may also place redemption orders directly by
contacting their local Schwab office by telephone, mail or in person, or by
mailing written instructions to Schwab (at the address listed on the Prospectus
cover page).
    
 
                                       20
<PAGE>   49
 
   
Normally a check for a shareholder's redemption proceeds will be available at
the investor's local Schwab office on the Business Day after Schwab's Mutual
Fund Transfer Agency Department receives proper redemption instructions. Checks
will normally be mailed to investors who specifically request such mailing on
the Business Day following share redemption. If you purchased shares by check,
your redemption proceeds may be held in your Schwab account until your check
clears (which may take up to 15 days). Depending on the type of Schwab account
you have, your money may earn interest during any holding period.
    
 
   
The Fund may suspend redemption rights or postpone payments at times when
trading on the Exchange is restricted, the Exchange is closed for any reason
other than its customary weekend or holiday closings, emergency circumstances as
determined by the SEC exist, or for such other circumstances as the SEC may
permit.
    
 
OTHER IMPORTANT INFORMATION
 
   
MINIMUM BALANCE AND BROKERAGE ACCOUNT REQUIREMENTS. Due to the relatively high
cost of maintaining smaller holdings, the Fund reserves the right to redeem a
shareholder's shares if, as a result of redemptions, their aggregate value drops
below the $100 minimum balance requirement for the Sweep Shares of the Fund. The
Fund will notify shareholders in writing 30 days before taking such action to
allow them to increase their holdings to at least the minimum level. Also note
that, because they can only be held in Schwab accounts, Fund shares will be
automatically redeemed should the Schwab account in which they are carried be
closed.
    
 
   
CONSOLIDATED MAILINGS. In an effort to reduce the Fund's mailing costs, the Fund
consolidates shareholder mailings by household. This consolidation means that a
household having multiple accounts with the identical address of record will
receive a single package during each shareholder mailing. If you do not wish
this consolidation to apply to your account(s), please write to SchwabFunds(R)
at 101 Montgomery Street, San Francisco, CA 94104 to that effect.
    
 
   
WIRE TRANSFERS TO YOUR BANK. If you so instruct your local Schwab office, funds
can be wired from your Schwab account to your bank account. Call your local
Schwab office for additional information. A $15 service fee will be charged
against your Schwab account for each wire sent.
    
 
SCHWAB ONE(R) ACCOUNT FEATURES. Shareholders who hold shares of the Fund in
Schwab One accounts are entitled to redeem Fund shares through debit cards and
checks. Investors should contact Schwab if they are interested in the benefits
and requirements of a Schwab One account.

maximum management fee for the Fund would be 0.46% of the Fund's average daily
net assets.
    
 
   
2 This amount reflects the guarantee by the Investment Manager and Schwab that,
through at least April 30, 1996, the total fund operating expenses of the Fund
will not exceed 0.73% of the Fund's average daily net assets. Without this
guarantee, the Fund's annualized total operating expenses would have been 1.05%
of the Fund's average daily net assets for the period ended December 31, 1994.

Note: During the period ended December 31, 1994, the Investment Manager and
Schwab reduced a portion of their fees in order to limit the Fund's ratio of
operating expenses to average net assets. Had these fees not been reduced, the
ratio of expenses to average net assets for the above-referenced period would
have been 1.05%* and the ratio of net investment income to average net assets
would have been 3.72%*.
    
 
INVESTMENT OBJECTIVE AND POLICIES
--------------------------------------------------------------------------------
THE FUND SEEKS MAXIMUM CURRENT INCOME CONSISTENT WITH STABILITY OF CAPITAL.
--------------------------------------------------------------------------------
 
   
The investment objective of the Schwab Retirement Money Fund(TM) is maximum
current income consistent with liquidity and stability of capital. This
investment objective is fundamental, and cannot be changed without approval by
holders of a majority of its outstanding voting shares, as defined in the
Investment Company Act of 1940, as amended (the "1940 Act"). The Fund will only
purchase securities that mature in 397 days or less, or which have a variable
rate of interest readjusted no less frequently than every 397 days. The Fund
pursues its objective by investing in the following types


* Annualized
 
                                        4
<PAGE>   57
 
of U.S. dollar-denominated debt instruments which are determined by the
Investment Manager to present minimal credit risk:
     

1. Bank certificates of deposit, time deposits or bankers' acceptances of
   domestic banks (including their foreign branches), United States branches of
   foreign banks and foreign branches of foreign banks having capital, surplus
   and undivided profits in excess of $100 million.
 
2. Commercial paper rated in the two highest rating categories by any nationally
   recognized statistical rating organization ("NRSRO"), including Moody's
   Investors Service, Standard & Poor's Corporation, Duff & Phelps, Inc., Fitch
   Investor Services, Inc., or commercial paper or notes of issuers with an
   unsecured debt issue outstanding currently rated in the two highest rating
   categories of any NRSRO, where the obligation is on the same or a higher
   level of priority and collateralized to the same extent as the rated issue.
   The Fund may also invest in other corporate obligations such as publicly
   traded bonds, debentures and notes rated in the two highest rating categories
   of any NRSRO and other similar securities which, if unrated by any NRSRO, are
   determined by the Investment Manager, using guidelines approved by the Board
   of Trustees, to be at least equal in quality to one or more of the above
   referenced securities. Notwithstanding the foregoing, the Fund may invest no
   more than 5% of its total assets in securities that are given the second
   highest rating by any NRSRO. The purchase of securities rated by only one
   NRSRO must be approved by the Board of Trustees of the Schwab Fund Family.
   (For a description of the ratings, see "Appendix -- Ratings of Investment
   Securities" in the Statement of Additional Information.)
 
3. Obligations of, or guaranteed by, the United States or Canadian governments,
   their agencies or instrumentalities.
 
4. Repurchase agreements involving obligations that are suitable for investment
   under the categories set forth above.
 
INVESTMENT TECHNIQUES. U.S. Treasury notes, bills and bonds are backed by the
full faith and credit of the U.S. Government. Some securities issued by U.S.
Government agencies or instrumentalities are supported only by the credit of the
agency or instrumentality, for example, those issued by the Federal Home Loan
Bank, while others, such as those issued by the Federal National Mortgage
Association, Farm Credit System and Student Loan Marketing Association have an
additional line of credit with the U.S. Treasury. With respect to securities
supported only by the credit of the issuing agency or instrumentality or by an
additional line of credit with the U.S. Treasury, there is no guarantee that the
U.S. Government will provide support to such agencies or instrumentalities.
Accordingly, such securities may involve risk of loss of principal and interest.
To the extent that the Fund purchases Eurodollar certificates of deposit,
consideration will be given to their marketability and possible restrictions on
international currency transactions, and to regulations imposed by the domicile
country of the foreign issuer. Eurodollar certificates of deposit may not be
subject to the same regulatory requirements as certificates of deposit issued by
U.S. banks and associated income may be subject to the imposition of foreign
taxes.
 
Investments in securities of foreign issuers or securities principally traded
overseas may involve certain special risks due to foreign economic, political
and legal developments, including favorable or
 
                                        5
<PAGE>   58
 
unfavorable changes in currency exchange rates, exchange control regulations
(including currency blockage), expropriation of assets or nationalization,
imposition of withholding taxes on dividend or interest payments, and possible
difficulty in obtaining and enforcing judgments against foreign entities.
Furthermore, issuers of foreign securities are subject to different, often less
comprehensive, accounting, reporting and disclosure requirements than domestic
issuers. The securities of some foreign companies and foreign securities markets
are less liquid and at times more volatile than securities of comparable U.S.
companies and U.S. securities markets. Foreign brokerage commissions and other
fees are also generally higher than in the United States. There are also special
tax considerations which apply to securities of foreign issuers and securities
principally traded overseas.
 
The Fund may invest in commercial paper issued in reliance on the so-called
"private placement" exemption from registration afforded by Section 4(2) of the
Securities Act of 1933, and resold to qualified institutional buyers under
Securities Act Rule 144A ("Section 4(2) paper"). Section 4(2) paper is generally
sold to institutional investors such as the Fund who agree that they are
purchasing the paper for investment and not with a view to public distribution.
Section 4(2) paper normally is resold to other institutional investors like the
Fund through or with the assistance of the issuer or investment dealers who make
a market in the Section 4(2) paper, thus providing liquidity. Because it is not
possible to predict with assurance exactly how the market for Section 4(2) paper
sold and offered under Rule 144A will develop, the Investment Manager, pursuant
to the guidelines approved by the Board of Trustees, will carefully monitor the
Fund's investments in these securities, focusing on such important factors,
among others, as valuation, liquidity, and availability of information.
Investments in Section 4(2) paper could have the effect of reducing the Fund's
liquidity to the extent that qualified institutional buyers become for a time
uninterested in purchasing these restricted securities. The Fund will not invest
more than 10% of its assets in Section 4(2) paper and illiquid securities unless
the Investment Manager determines, by continuous reference to the appropriate
trading markets and pursuant to guidelines approved by the Board of Trustees,
that any Section 4(2) paper held by the Fund in excess of this level is at all
times liquid. The Fund will invest no more than 15% of its assets in restricted
securities.
 
The Fund may invest in securities backed by automobile receivables and
credit-card receivables and other securities backed by other types of
receivables. Credit support for asset-backed securities may be based on the
underlying assets or provided by a third party. Credit enhancement techniques
include letters of credit, insurance bonds, limited guarantees (which are
generally provided by the issuer), senior-subordinated structures and over
collateralization. Asset-backed securities purchased by the Fund will be subject
to the same quality requirements as other securities purchased by the Fund.
 
The Fund may purchase securities on a "when-issued" or "delayed delivery" basis.
When-issued or delayed delivery securities are securities purchased for future
delivery at a stated price and yield. The Fund will generally not pay for such
securities or start earning interest on them until they are received. Securities
purchased on a when-issued or delayed delivery basis are recorded as an asset
and are subject to changes in value based upon changes in the general level of
interest rates. The Fund will not invest more than 25% of its assets in
when-issued or delayed delivery securities, does not intend to purchase such
securities for speculative purposes and will make commitments to purchase
 
                                        6
<PAGE>   59
 
securities on a when-issued or delayed delivery basis with the intention of
actually acquiring the securities. However, the Fund reserves the right to sell
acquired when-issued or delayed delivery securities before their settlement
dates if deemed advisable.
 
The Fund may invest in repurchase agreements, which are instruments under which
the Fund acquires ownership of a security from a broker-dealer or bank that
agrees to repurchase the security at a mutually agreed upon time and price
(which price is higher than the purchase price), thereby determining the yield
during the Fund's holding period. Maturity of the securities subject to
repurchase may exceed one year. In the event of a bankruptcy or other default of
a seller of a repurchase agreement, the Fund might have expenses in enforcing
its rights, and could experience losses, including a decline in the value of the
underlying securities and loss of income. The Fund will only enter into
repurchase agreements with banks and other recognized financial institutions
such as broker/dealers which are deemed by the Fund's Investment Manager to be
creditworthy. The Fund will not purchase illiquid securities, including time
deposits and repurchase agreements maturing in more than seven days, if, as a
result thereof, more than 10% of the Fund's net assets valued at the time of the
transaction would be invested in such securities.
 
The Fund may invest in instruments having rates of interest that are adjusted
periodically or which "float" continuously according to formulae intended to
minimize fluctuation in values of the instruments ("Variable Rate Securities").
The interest rate of Variable Rate Securities ordinarily is determined by
reference to, or is a percentage of, an objective standard such as a bank's
prime rate, the 90-day U.S. Treasury Bill rate, or the rate of return on
commercial paper or bank certificates of deposit. Generally, the changes in the
interest rate on Variable Rate Securities reduce the fluctuation in the market
value of such securities. Accordingly, as interest rates decrease or increase,
the potential for capital appreciation or depreciation is less than for
fixed-rate obligations. Some Variable Rate Securities ("Variable Rate Demand
Securities") have a demand feature entitling the purchaser to resell the
securities at an amount approximately equal to amortized cost or the principal
amount thereof plus accrued interest. As is the case for other Variable Rate
Securities, the interest rate on Variable Rate Demand Securities varies
according to some objective standard intended to minimize fluctuation in the
values of the instruments.
 
The Fund determines the maturity of Variable Rate Securities in accordance with
Securities and Exchange Commission rules which allow the Fund to consider
certain of such instruments as having maturities shorter than the maturity date
on the face of the instrument. Under such rules, the maturity date may be
considered to be the longer of the period remaining until the next readjustment
of the interest rate or the period remaining until the principal amount can be
recovered through demand.
 
To increase its income, the Fund may lend its portfolio securities to brokers,
dealers and other financial institutions that borrow securities. No more than
one-third of the Fund's total assets may be represented by loaned securities.
The Fund's loans of portfolio securities will be fully collateralized by cash,
letters of credit or U.S. Government securities equal at all times to at least
100% of the loaned securities' market value plus accrued interest. As with other
extensions of credit, there are risks of delay in recovery or even losses of
rights in the securities loaned should the borrower of the securities fail
financially. However, such loans will be made only to firms deemed by the
Investment Manager to
 
                                        7
<PAGE>   60
 
be of good standing and when, in the judgment of the Investment Manager, the
income which can be earned currently from such loans justifies the attendant
risk.
 
The Fund may not borrow money except as a temporary measure for extraordinary or
emergency purposes, and then only in an amount up to one-third of the value of
its total assets, in order to meet redemption requests without immediately
selling any portfolio securities. The Fund will not borrow for leverage
purposes.
 
MANAGEMENT OF THE FUND
 
   
Responsibility for overall management of the Fund rests with the trustees and
officers of the Schwab Fund Family. Professional investment management for the
Fund is provided by the Investment Manager, Charles Schwab Investment
Management, Inc., 101 Montgomery Street, San Francisco, CA 94104. The Investment
Manager provides a continuous investment program, including general investment
and economic advice regarding the Fund's investment strategies, manages the
Fund's investment portfolio and performs expense management, accounting and
record keeping, and provides other services necessary to the operation of the
Fund and the Schwab Fund Family. The Investment Manager, formed in 1989, is a
wholly-owned subsidiary of The Charles Schwab Corporation and is the investment
adviser and administrator of the SchwabFunds(R) mutual funds. As of July 31,
1995, the SchwabFunds had aggregate net assets over $28 billion.
    
 
Charles Schwab & Co., Inc., ("Schwab" or the "Transfer Agent") 101 Montgomery
Street, San Francisco, CA 94104, serves as shareholder services agent and
transfer agent for the Fund. Schwab provides information and services to
shareholders, which include reporting share ownership, sales and dividend
activity (and associated tax consequences), responding to daily inquiries, and
effecting the transfer of Fund shares. It also furnishes such office space and
equipment, telephone facilities, personnel and informational literature
distribution as is necessary or appropriate in providing the described
shareholder and transfer agency information and services. Schwab is also the
Fund's distributor, but receives no compensation for its services as such.
 
   
Schwab was established in 1971 and is one of America's largest discount brokers.
The firm provides low-cost securities brokerage and related financial services
to over 2.5 million active customer accounts and has over 200 branch offices.
Schwab is a wholly-owned subsidiary of The Charles Schwab Corporation. Charles
R. Schwab is the founder, Chairman and Chief Executive Officer and a director of
The Charles Schwab Corporation and, as of July 31, 1995, the beneficial owner of
approximately 20.5% of the outstanding shares of that corporation. Mr. Schwab
may be deemed to be a controlling person of Schwab and the Investment Manager.
    
 
   
FEES AND EXPENSES. Pursuant to its Investment Advisory and Administration
Agreement with the Schwab Fund Family, the Investment Manager receives from the
Fund a graduated annual fee, payable monthly, of 0.46% of the Fund's average
daily net assets not in excess of $2 billion, 0.45% of such assets over $2
billion but not in excess of $3 billion, and 0.40% of such net assets over $3
billion. The Investment Manager has guaranteed that, through at least April 30,
1996, this fee will not exceed 0.44% of the Fund's average daily net assets. Fee
reductions lower the Fund's expenses and thus increase the total return it
provides shareholders.
    
 
                                        8
<PAGE>   61
 
For transfer agency services provided to the Fund, Schwab receives an annual
fee, payable monthly, of 0.05% of the Fund's average daily net assets. In
addition, for shareholder services provided, Schwab receives an annual fee,
payable monthly, of 0.20% of the Fund's average daily net assets.
 
   
The Investment Manager and Schwab have guaranteed that, through at least April
30, 1996, the Fund's total fund operating expenses will not exceed 0.73% of the
Fund's average daily net assets. The effect of this voluntary expense limit is
to maintain or increase the Fund's total return to shareholders. For the fiscal
period ended December 31, 1994, the Fund paid investment management fees of
0.36%* of the Fund's average daily net assets and paid total expenses of 0.73%*
of the Fund's average daily net assets. The Fund's custodian is PNC Bank.
    
 
The Schwab Fund Family pays the expenses of its operations, including the fees
and expenses of independent auditors, counsel, custodians, and the cost of
calculating net asset value, brokerage commissions or transaction costs, taxes,
registration fees, the fees and expenses of qualifying the Schwab Fund Family
and its shares for distribution under federal and state securities laws and
industry association membership dues. The described expenses are generally
allocated among the Schwab Fund Family's investment portfolios on the basis of
relative net assets at the time of allocation, except that expenses directly
attributable to the Fund are charged to the Fund.
 
DISTRIBUTIONS AND TAXES
--------------------------------------------------------------------------------
THE FUND DECLARES DAILY DIVIDENDS WHICH ARE PAID MONTHLY.
--------------------------------------------------------------------------------
 
   
DIVIDENDS AND OTHER DISTRIBUTIONS. On each day that the net asset value per
share of the Fund is determined ("Business Day"), the Fund's net investment
income is declared as of 4:00 p.m. Eastern time as a dividend to shareholders of
record at that time. Dividends are normally paid (and, where applicable,
reinvested) on the 15th of each month, if a Business Day, otherwise on the next
Business Day.
    
 
   
FEDERAL INCOME TAX INFORMATION. The Fund intends to elect to be treated as a
regulated investment company under the Internal Revenue Code of 1986, as amended
(the "Code"). In order to so qualify, the Fund will distribute substantially all
of its investment company taxable income and net capital gains and will meet
certain other requirements. Such qualification relieves the Fund of liability
for federal income taxes to the extent it earnings are distributed.
    
 
All distributions are taxable to shareholders as ordinary income, except that
long-term capital gains distributions (if any) are taxable as such regardless of
how long the shareholder has had the shares. Reinvested distributions will be
taxable as if they had been received by shareholders in cash. It is not expected
that any portion of the dividends paid by the Fund will qualify for the
corporate dividends received deduction.
 
Records of dividends and other distributions, purchases and redemptions will be
reflected on shareholders' account statements. The Fund will notify shareholders
at least annually as to the federal
* Annualized
 
                                        9
<PAGE>   62
 
income tax consequences of distributions made each year. The Fund does not
expect to realize any net long-term capital gains and, therefore, does not
foresee paying any capital gains dividends.
 
The foregoing is only a brief summary of some of the federal income tax
considerations affecting the Fund and its shareholders. Accordingly, potential
investors in the Fund should consult their tax advisers with specific reference
to their own tax situations, particularly if the investor is purchasing through
a retirement plan.
 
SHARE PRICE CALCULATION
 
The price of Fund shares on any given day is their "net asset value" or "NAV."
This figure is computed by dividing total Fund assets, less any liabilities, by
the number of Fund shares outstanding. The net asset value per share of the Fund
is determined on each day both the Federal Reserve Bank of New York and the New
York Stock Exchange (the "Exchange") are open for business as of 4:00 p.m.
Eastern time. While the Fund attempts to maintain its net asset value at a
constant $1.00 per share, Fund shares are not insured against a reduction in net
asset value.
 
The Fund values its portfolio securities at amortized cost, which means that
they are valued at their acquisition cost (as adjusted for amortization of
premium or discount) rather than at current market value. Calculations are made
to compare the value of the Fund's investments using the amortized cost method
with market values. Market valuations are obtained by using actual quotations
provided by market makers, estimates of market value, or values obtained from
yield data relating to comparable classes of money market instruments published
by reputable sources at the mean between the bid and asked prices for the
instruments. If a deviation of 1/2 of 1% or more were to occur between the
Fund's net asset value per share calculated by reference to market values and
the Fund's $1.00 per share amortized cost value, or if there were any other
deviation which the Board of Trustees believed would result in a material
dilution to shareholders or purchases, the Board of Trustees would promptly
consider what action, if any, should be initiated.
 
HOW THE FUND SHOWS PERFORMANCE
 
From time to time the Fund may advertise its yield and effective yield.
Performance figures are based upon historical results and are not intended to
indicate future performance.
 
   
The yield of a Fund refers to the income generated by a hypothetical investment
in the Fund over a specific 7-day period. This income is then annualized, which
means that the income generated during the 7-day period is assumed to be
generated each week over an annual period and is shown as a percentage of the
hypothetical investment.
    
 
Effective yield is calculated similarly, but the income earned by the investment
is assumed to be compounded weekly when annualized. The effective yield will be
slightly higher than the yield due to this compounding effect. (See "Yield" in
the Statement of Additional Information.)
 
The performance of the Fund may be compared to that of other mutual funds
tracked by mutual fund rating services, various indices of investment
performance, United States government obligations, bank certificates of deposit,

GENERAL INFORMATION
 
   
The Schwab Fund Family was organized as a business trust under the laws of
Massachusetts on October 20, 1989 and may issue an unlimited number of shares of
beneficial interest in one or more investment portfolios or series ("Series").
Currently, shares of nine Series are offered. The Board of Trustees may
authorize the issuance of shares of additional Series if deemed desirable.
Shares of each Series or class have equal, non cumulative voting rights and
equal rights as to dividends, assets, and liquidation of such Series.
    
 
   
The Schwab Fund Family is not required to hold annual shareholders' meetings. It
will, however, hold special meetings as required or deemed desirable by the
Board of Trustees for such purposes as electing trustees, changing fundamental
policies or approving an investment advisory agreement. Shareholders will vote
by Series and not in the aggregate (for example, when voting to approve the
investment advisory agreement), except when voting in the aggregate is permitted
under the 1940 Act, such as for the election of Trustees.
    
 
SHAREHOLDER GUIDE
--------------------------------------------------------------------------------
SCHWAB'S OFFICES ACCEPT ORDERS AND PROVIDE SHAREHOLDER SERVICE AND INFORMATION.
--------------------------------------------------------------------------------
 
SHAREHOLDER SERVICE. You may place Fund purchase and redemption orders as well
as request exchanges by calling your Schwab representative who is available to
answer questions about the Fund and your account. The privilege to initiate
transactions by telephone, as discussed below, is automatically available
through your Schwab account. The Fund will employ reasonable procedures to

acting upon instructions received by telephone, providing written confirmation
of such instructions and tape recording telephone transactions.
 
HOW TO PURCHASE SHARES
 
You may purchase shares of the Fund through an account maintained with Schwab or
The Charles Schwab Trust Company, and payment for shares must be made directly
to Schwab or The Charles Schwab Trust Company. A $1,000 minimum deposit of cash
and/or securities is required to open an account maintained with Schwab or The
Charles Schwab Trust Company.
 
The minimum initial investment is $1, and subsequent investments must be at
least $1.
 
You may deposit funds into your account by check or wire. All deposit checks
should be made payable to Charles Schwab & Co., Inc. or The Charles Schwab Trust
Company. If you would like to wire funds into your account, please contact your
Schwab representative for instructions.

    
WHEN AND AT WHAT PRICE SHARES WILL BE PURCHASED. You must have funds in your

<PAGE>   64
 
before 4:00 p.m. (Eastern time), they will be available for investment on the
day of receipt and will generally begin earning dividends the next Business Day.
If funds arrive after that time, they will be available for investment the next
Business Day. Orders to purchase shares will be executed at the next determined
net asset value after receipt by Schwab's Mutual Fund Transfer Agent Department.
(See "Share Price Calculation.")
    
 
AUTOMATIC REINVESTMENT. Distributions will be reinvested in additional full and
fractional shares of the Fund at the net asset value next determined on their
payable date.
 
OTHER PURCHASE INFORMATION. The Fund reserves the right, in its sole discretion
and without prior notice to shareholders, to withdraw or suspend all or any part
of the offering made by this Prospectus, to reject purchase orders or to change
the minimum investment requirements. All orders to purchase shares of the Fund
are subject to acceptance by the Fund and are not binding until confirmed or
accepted in writing. Schwab will charge a $15 service fee against an investor's
account should his or her check be returned because of insufficient or
uncollected funds or a stop payment order.
 
   
HOW TO EXCHANGE SHARES
    
------------------------------------------------------------------------------
   
SHARES OF THE FUND MAY BE EXCHANGED FOR SHARES OF OTHER
FUNDS SPONSORED BY SCHWAB WITHOUT CHARGE.
    
------------------------------------------------------------------------------
 
   
The exchange privilege allows you to exchange your investment in the Fund for
shares of other SchwabFunds(R) available to investors in your state if your
purchase meets that fund's eligibility requirements. Thus, you can conveniently
modify your investments if your goals or market conditions change. An exchange
will involve the redemption of Fund shares at the net asset value next
determined after receipt by Schwab's Mutual Fund Transfer Agency Department of
an exchange request, and the purchase of shares in another fund at the net asset
value of that fund next determined after purchase of the fund shares involved in
the exchange. An exchange will be treated as a sale of the shares for federal
income tax purposes. Note that you must meet the minimum initial or subsequent
investment requirements applicable to the shares you wish to receive in
exchange. Only investors who may purchase shares of the Fund may exchange shares
of other SchwabFunds for shares of the Fund. The Fund reserves the right on 60
days' written notice to modify, limit or terminate the exchange privilege.
    
 
METHODS OF EXCHANGING SHARES
 
BY PHONE:
 
To exchange between funds by telephone, please call your Schwab Representative
during regular business hours. Investors should be aware that telephone
exchanges may be difficult to implement during periods of drastic economic or
market changes.
 
                                       12
<PAGE>   65
 
To properly process your telephone exchange request, we will need the following
information:
 
   
        - your Schwab account number and your name for verification;
    
   
        - the number of shares to be exchanged from the Fund;
    
   
        - the name of the fund into which shares are to be exchanged; and
    
   
        - the distribution option you select.
    
 
BY MAIL:
 
You may also request an exchange by writing Schwab at the address listed on the
Prospectus cover page.
 
To properly process your mailed exchange request, we will need a letter from you
which:
 
   
        - references your Schwab account number;
    
   
        - specifies that you would like to exchange shares from the Fund and the
          number of shares to be exchanged;
    
   
        - indicates the name of the fund into which shares are to be exchanged;
    
   
        - indicates the distribution option you select; and
    
   
        - is signed by at least one of the registered Schwab account holders, in
          the exact form specified in the account.
    
 
HOW TO REDEEM SHARES
 
   
THE PRICE AT WHICH SHARES WILL BE REDEEMED. Shares will be redeemed at the net
asset value per share next determined after receipt by Schwab's Mutual Fund
Transfer Agency Department of proper redemption instructions, as set forth
below. Investors will receive dividends declared for the day on which orders to
redeem shares are executed.
    
 
METHODS OF REDEEMING SHARES. Shareholders may place redemption orders by
contacting their Schwab Representative by telephone, by mail or in person.
Investors should be aware that telephone redemption may be difficult to
implement during periods of drastic economic or market changes. Shareholders who
experience difficulties in redeeming by telephone can utilize one of the just
mentioned alternatives to place their redemption orders.
 
   
Telephone redemption orders received prior to 4:00 p.m. (Eastern time) on any
Business Day, once they have been verified by the Transfer Agent, will be deemed
to have been received by Schwab's Mutual Fund Transfer Agency Department on that
day. All other telephone redemption orders will be considered received by
Schwab's Mutual Fund Transfer Agency Department on the following Business Day.
    
 
   
The Fund may suspend redemption rights or postpone payments at times when
trading on the Exchange is restricted, the Exchange is closed for any reason
other than its customary weekend or holiday closings, emergency circumstances as
determined by the SEC exist, or for such other circumstances as the SEC may
permit. The Fund may also elect to invoke a 7-day period for cash settlement of
individual redemption requests in excess of $250,000 or 1% of the Fund's net
assets, whichever is less.

this consolidation to apply to your account(s), please write to Schwab (at the
address listed on the Prospectus cover page) to that effect.

ANNUAL FUND OPERATING EXPENSES (AS A PERCENTAGE OF AVERAGE NET ASSETS):
  Management Fees (after fee reduction) 1...........................................    0.26%

</TABLE>
    
 
   
1 This amount reflects a reduction by the Investment Manager, which is
guaranteed through at least April 30, 1996. If there were no such reduction, the
maximum management fee for the Fund would be 0.46% of the Fund's average daily
net assets for the period ended December 31, 1994.
    
 
   
2 This amount has been restated to reflect the guarantee by the Investment
Manager and Schwab that, through at least April 30, 1996, the total fund
operating expenses will not exceed 0.50% of the Fund's average daily net assets.
Without a similar guarantee, which was in effect during the period ended
December 31, 1994, total annualized fund operating expenses would have been
0.92% of the Fund's average daily net assets.
    
 
                                        2

EXAMPLE. You would pay the following expenses on a $1,000 investment, assuming
(1) 5% annual return and (2) redemption at the end of each time period:

THE PURPOSE OF THE PRECEDING TABLE IS TO ASSIST INVESTORS IN UNDERSTANDING THE
VARIOUS COSTS AND EXPENSES THAT AN INVESTOR IN THE FUND WILL BEAR DIRECTLY OR
INDIRECTLY. This example reflects the guarantee by the Investment Manager and
Schwab that, through at least April 30, 1996, the total fund operating expenses
will not exceed 0.50% of the Fund's average daily net assets. ACTUAL EXPENSES
MAY BE GREATER OR LESS THAN THOSE SHOWN. The example assumes a 5% annual rate of
return pursuant to requirements of the SEC. THIS HYPOTHETICAL RATE OF RETURN IS
NOT INTENDED TO BE REPRESENTATIVE OF PAST OR FUTURE PERFORMANCE.

Note: During the period ended December 31, 1994, the Investment Manager and
Schwab reduced a portion of their fees in order to limit the Fund's ratio of
operating expenses to average net assets. Had these fees not been reduced, the
ratio of expenses to average net assets for the above-referenced period would
have been 0.92%* and the ratio of net investment income to average net assets
would have been 3.67%*.
    
 
INVESTMENT OBJECTIVE AND POLICIES
--------------------------------------------------------------------------------
THE FUND SEEKS MAXIMUM CURRENT INCOME CONSISTENT WITH STABILITY OF CAPITAL.
--------------------------------------------------------------------------------
 
   
The investment objective of the Schwab Institutional Advantage Money FundTM is
maximum current income consistent with liquidity and stability of capital. This
investment objective is fundamental, and cannot be changed without approval by
holders of a majority of its outstanding voting shares, as defined in the
Investment Company Act of 1940, as amended (the "1940 Act"). The Fund will only
purchase securities that mature in 397 days or less, or which have a variable
rate of interest readjusted
 

* Annualized
 
                                        4
<PAGE>   73
 
no less frequently than every 397 days. The Fund pursues its objective by
investing in the following types of U.S. dollar-denominated debt instruments
which are determined by the Investment Manager to present minimal credit risk:
     

1. Bank certificates of deposit, time deposits or bankers' acceptances of
   domestic banks (including their foreign branches), United States branches of
   foreign banks and foreign branches of foreign banks having capital, surplus
   and undivided profits in excess of $100 million.
 
   
2. Commercial paper rated in the top two rating categories by any nationally
   recognized statistical rating organization ("NRSRO"), including Moody's
   Investors Service, Standard & Poor's Corporation, Duff & Phelps, Inc., Fitch
   Investor Services, Inc., or commercial paper or notes of issuers with an
   unsecured debt issue outstanding currently rated in the top two rating
   categories of any NRSRO, where the obligation is on the same or a higher
   level of priority and collateralized to the same extent as the rated issue.
   The Fund may also invest in other corporate obligations such as publicly
   traded bonds, debentures and notes rated in the top two rating categories by
   any NRSRO and other similar securities which, if unrated by any NRSRO, are
   determined by the Investment Manager, using guidelines approved by the Board
   of Trustees, to be at least equal in quality to one or more of the above
   referenced securities. Notwithstanding the foregoing, the Fund may invest no
   more than 5% of its total assets in securities that are given the second
   highest rating by any NRSRO. The purchase of securities rated by only one
   NRSRO must be approved by the Board of Trustees of the Schwab Fund Family.
   (For a description of the ratings, see "Appendix -- Ratings of Investment
   Securities" in the Statement of Additional Information.)
    
 
3. Obligations of, or guaranteed by, the United States or Canadian governments,
   their agencies or instrumentalities.
 
4. Repurchase agreements involving obligations that are suitable for investment
   under the categories set forth above.
 
INVESTMENT TECHNIQUES. U.S. Treasury notes, bills and bonds are backed by the
full faith and credit of the U.S. Government. Some securities issued by U.S.
Government agencies or instrumentalities are supported only by the credit of the
agency or instrumentality, for example, those issued by the Federal Home Loan
Bank, while others, such as those issued by the Federal National Mortgage
Association, Farm Credit System and Student Loan Marketing Association have an
additional line of credit with the U.S. Treasury. With respect to securities
supported only by the credit of the issuing agency or instrumentality or by an
additional line of credit with the U.S. Treasury, there is no guarantee that the
U.S. Government will provide support to such agencies or instrumentalities.
Accordingly, such securities may involve risk of loss of principal and interest.
To the extent that the Fund purchases Eurodollar certificates of deposit,
consideration will be given to their marketability and possible restrictions on
international currency transactions, and to regulations imposed by the domicile
country of the foreign issuer. Eurodollar certificates of deposit may not be
subject to the same regulatory requirements as certificates of deposit issued by
U.S. banks and associated income may be subject to the imposition of foreign
taxes.

<PAGE>   74
 
Investments in securities of foreign issuers or securities principally traded
overseas may involve certain special risks due to foreign economic, political
and legal developments, including favorable or unfavorable changes in currency
exchange rates, exchange control regulations (including currency blockage),
expropriation of assets or nationalization, imposition of withholding taxes on
dividend or interest payments, and possible difficulty in obtaining and
enforcing judgments against foreign entities. Furthermore, issuers of foreign
securities are subject to different, often less comprehensive, accounting,
reporting and disclosure requirements than domestic issuers. The securities of
some foreign companies and foreign securities markets are less liquid and at
times more volatile than securities of comparable U.S. companies and U.S.
securities markets. Foreign brokerage commissions and other fees are also
generally higher than in the United States. There are also special tax
considerations which apply to securities of foreign issuers and securities
principally traded overseas.
 
The Fund may invest in commercial paper issued in reliance on the so-called
"private placement" exemption from registration afforded by Section 4(2) of the
Securities Act of 1933, and resold to qualified institutional buyers under
Securities Act Rule 144A ("Section 4(2) paper"). Section 4(2) paper is generally
sold to institutional investors such as the Fund who agree that they are
purchasing the paper for investment and not with a view to public distribution.
Section 4(2) paper normally is resold to other institutional investors like the
Fund through or with the assistance of the issuer or investment dealers who make
a market in the Section 4(2) paper, thus providing liquidity. Because it is not
possible to predict with assurance exactly how the market for Section 4(2) paper
sold and offered under Rule 144A will develop, the Investment Manager, pursuant
to the guidelines approved by the Board of Trustees, will carefully monitor the
Fund's investments in these securities, focusing on such important factors,
among others, as valuation, liquidity, and availability of information.
Investments in Section 4(2) paper could have the effect of reducing the Fund's
liquidity to the extent that qualified institutional buyers become for a time
uninterested in purchasing these restricted securities. The Fund will not invest
more than 10% of its assets in Section 4(2) paper and illiquid securities unless
the Investment Manager determines, by continuous reference to the appropriate
trading markets and pursuant to guidelines approved by the Board of Trustees,
that any Section 4(2) paper held by the Fund in excess of this level is at all
times liquid. The Fund will invest no more than 15% of its assets in restricted
securities.
 
The Fund may invest in securities backed by automobile receivables and
credit-card receivables and other securities backed by other types of
receivables. Credit support for asset-backed securities may be based on the
underlying assets or provided by a third party. Credit enhancement techniques
include letters of credit, insurance bonds, limited guarantees (which are
generally provided by the issuer), senior-subordinated structures and over
collateralization. Asset-backed securities purchased by the Fund will be subject
to the same quality requirements as other securities purchased by the Fund.
 
The Fund may purchase securities on a "when-issued" or "delayed delivery" basis.
When-issued or delayed delivery securities are securities purchased for future
delivery at a stated price and yield. The Fund will generally not pay for such
securities or start earning interest on them until they are received. Securities
purchased on a when-issued or delayed delivery basis are recorded as an asset
and are subject to changes in value based upon changes in the general level of
interest rates. The Fund will
 
                                        6
<PAGE>   75
 
not invest more than 25% of it assets in when-issued or delayed delivery
securities, does not intend to purchase such securities for speculative purposes
and will make commitments to purchase securities on a when-issued or delayed
delivery basis with the intention of actually acquiring the securities. However,
the Fund reserves the right to sell acquired when-issued or delayed delivery
securities before their settlement dates if deemed advisable.
 
The Fund may invest in repurchase agreements, which are instruments under which
the Fund acquires ownership of a security from a broker-dealer or bank that
agrees to repurchase the security at a mutually agreed upon time and price
(which price is higher than the purchase price), thereby determining the yield
during the Fund's holding period. Maturity of the securities subject to
repurchase may exceed one year. In the event of a bankruptcy or other default of
a seller of a repurchase agreement, the Fund might have expenses in enforcing
its rights, and could experience losses, including a decline in the value of the
underlying securities and loss of income. The Fund will only enter into
repurchase agreements with banks and other recognized financial institutions
such as broker/dealers which are deemed by the Fund's Investment Manager to be
creditworthy. The Fund will not purchase illiquid securities, including time
deposits and repurchase agreements maturing in more than seven days, if, as a
result thereof, more than 10% of the Fund's net assets valued at the time of the
transaction would be invested in such securities.
 
The Fund may invest in instruments having rates of interest that are adjusted
periodically or which "float" continuously according to formulae intended to
minimize fluctuation in values of the instruments ("Variable Rate Securities").
The interest rate of Variable Rate Securities ordinarily is determined by
reference to, or is a percentage of, an objective standard such as a bank's
prime rate, the 90-day U.S. Treasury Bill rate, or the rate of return on
commercial paper or bank certificates of deposit. Generally, the changes in the
interest rate on Variable Rate Securities reduce the fluctuation in the market
value of such securities. Accordingly, as interest rates decrease or increase,
the potential for capital appreciation or depreciation is less than for
fixed-rate obligations. Some Variable Rate Securities ("Variable Rate Demand
Securities") have a demand feature entitling the purchaser to resell the
securities at an amount approximately equal to amortized cost or the principal
amount thereof plus accrued interest. As is the case for other Variable Rate
Securities, the interest rate on Variable Rate Demand Securities varies
according to some objective standard intended to minimize fluctuation in the
values of the instruments.
 
The Fund determines the maturity of Variable Rate Securities in accordance with
Securities and Exchange Commission rules which allow the Fund to consider
certain of such instruments as having maturities shorter than the maturity date
on the face of the instrument. Under such rules, the maturity date may be
considered to be the longer of the period remaining until the next readjustment
of the interest rate or the period remaining until the principal amount can be
recovered through demand.
 
To increase its income, the Fund may lend its portfolio securities to brokers,
dealers and other financial institutions that borrow securities. No more than
one-third of the Fund's total assets may be represented by loaned securities.
The Fund's loans of portfolio securities will be fully collateralized by cash,
letters of credit or U.S. Government securities equal at all times to at least
100% of the loaned securities' market value plus accrued interest. As with other
extensions of credit, there are risks of
 
                                        7
<PAGE>   76
 
delay in recovery or even losses of rights in the securities loaned should the
borrower of the securities fail financially. However, such loans will be made
only to firms deemed by the Investment Manager to be of good standing and when,
in the judgment of the Investment Manager, the income which can be earned
currently from such loans justifies the attendant risk.
 
The Fund may not borrow money except as a temporary measure for extraordinary or
emergency purposes, and then only in an amount up to one-third of the value of
its total assets, in order to meet redemption requests without immediately
selling any portfolio securities. The Fund will not borrow for leverage
purposes.
 
MANAGEMENT OF THE FUND
 
   
Responsibility for overall management of the Fund rests with the trustees and
officers of the Schwab Fund Family. Professional investment management for the
Fund is provided by the Investment Manager, Charles Schwab Investment
Management, Inc., 101 Montgomery Street, San Francisco, CA 94104. The Investment
Manager provides a continuous investment program, including general investment
and economic advice regarding the Fund's investment strategies, manages the
Fund's investment portfolio and performs expense management, accounting and
record keeping, and provides other services necessary to the operation of the
Fund and the Schwab Fund Family. The Investment Manager, formed in 1989, is a
wholly-owned subsidiary of The Charles Schwab Corporation and is the investment
adviser and administrator of the SchwabFunds(R) mutual funds. As of July 31,
1995, the SchwabFunds had aggregate net assets over $28 billion.
    
 
Charles Schwab & Co., Inc., ("Schwab" or the "Transfer Agent") 101 Montgomery
Street, San Francisco, CA 94104, serves as shareholder services agent and
transfer agent for the Fund. Schwab provides information and services to
shareholders, which include reporting share ownership, sales and dividend
activity (and associated tax consequences), responding to daily inquiries, and
effecting the transfer of Fund shares. It also furnishes such office space and
equipment, telephone facilities, personnel and informational literature
distribution as is necessary or appropriate in providing the described
shareholder and transfer agency information and services. Schwab is also the
Fund's distributor, but receives no compensation for its services as such.
 
   
Schwab was established in 1971 and is one of America's largest discount brokers.
The firm provides low-cost securities brokerage and related financial services
to over 2.5 million active customer accounts and has over 200 branch offices.
Schwab is a wholly-owned subsidiary of The Charles Schwab Corporation. Charles
R. Schwab is the founder, Chairman and Chief Executive Officer and a director of
The Charles Schwab Corporation and, as of July 31, 1995, the beneficial owner of
approximately 20.5% of the outstanding shares of that corporation. Mr. Schwab
may be deemed to be a controlling person of Schwab and the Investment Manager.
    
 
   
FEES AND EXPENSES. Pursuant to its Investment Advisory and Administration
Agreement with the Schwab Fund Family, the Investment Manager receives from the
Fund a graduated annual fee, payable monthly, of 0.46% of the Fund's average
daily net assets not in excess of $2 billion, 0.45% of such assets over $2
billion but not in excess of $3 billion, and 0.40% of such net assets over $3
billion. The Investment Manager has guaranteed that, through at least April 30,
1996, this fee will not exceed

 
                                        8
<PAGE>   77
 
0.26% of the Fund's average daily net assets. Fee reductions lower the Fund's
expenses and thus increase the total return it provides shareholders.
     

For transfer agency services provided to the Fund, Schwab receives an annual
fee, payable monthly, of 0.05% of the Fund's average daily net assets. In
addition, for shareholder services provided, Schwab receives an annual fee,
payable monthly, of 0.20% of the Fund's average daily net assets.
 
   
The Investment Manager and Schwab have guaranteed that, through at least April
30, 1996, the Fund's total fund operating expenses will not exceed 0.50% of the
Fund's average daily net assets. The effect of this voluntary expense limit is
to maintain or increase the Fund's total return to shareholders. For the fiscal
period ended December 31, 1994, the Fund paid investment management fees of
0.26%* of the Fund's average daily net assets and paid total expenses of 0.55%*
of the Fund's average daily net assets. The Fund's custodian is PNC Bank.
    
 
The Schwab Fund Family pays the expenses of its operations, including the fees
and expenses of independent auditors, counsel, custodians, and the cost of
calculating net asset value, brokerage commissions or transaction costs, taxes,
registration fees, the fees and expenses of qualifying the Schwab Fund Family
and its shares for distribution under federal and state securities laws and
industry association membership dues. The described expenses are generally
allocated among the Schwab Fund Family's investment portfolios on the basis of
relative net assets at the time of allocation, except that expenses directly
attributable to the Fund are charged to the Fund.
 
DISTRIBUTIONS AND TAXES
--------------------------------------------------------------------------------
THE FUND DECLARES DAILY DIVIDENDS WHICH ARE PAID MONTHLY.
--------------------------------------------------------------------------------
 
   
DIVIDENDS AND OTHER DISTRIBUTIONS. On each day that the net asset value per
share of the Fund is determined ("Business Day"), the Fund's net investment
income is declare as of 4:00 p.m. Eastern time as a dividend to shareholders of
record at that time. Dividends are normally paid (and, where applicable,
reinvested) on the 15th of each month, if a Business Day, otherwise on the next
Business Day.
    
 
   
FEDERAL INCOME TAX INFORMATION. The Fund intends to elect to be treated as a
regulated investment company under the Internal Revenue Code of 1986, as amended
(the "Code"). In order to so qualify, the Fund will distribute substantially all
of its investment company taxable income and net capital gains and will meet
certain other requirements. Such qualification relieves the Fund of liability
for federal income taxes to the extent it earnings are distributed.
    
 
All distributions are taxable to shareholders as ordinary income, except that
long-term capital gains distributions (if any) are taxable as such regardless of
how long the shareholder has held the shares. Reinvested distributions will be
taxable as if they had been received by shareholders in cash. It is not expected
that any portion of the dividends paid by the Fund will qualify for the
corporate dividends received deduction.
 
   
* Annualized
    
 
                                        9
<PAGE>   78
 
Records of dividends and other distributions, purchases and redemptions will be
reflected on shareholders' account statements. The Fund will notify shareholders
at least annually as to the federal income tax consequences of distributions
made each year. The Fund does not expect to realize any net long-term capital
gains and, therefore, does not foresee paying any capital gains dividends.
 
The foregoing is only a brief summary of some of the federal income tax
considerations affecting the Fund and its shareholders. Accordingly, potential
investors in the Fund should consult their tax advisers with specific reference
to their own tax situations, particularly if the investor is purchasing through
a retirement plan.
 
SHARE PRICE CALCULATION
 
The price of Fund shares on any given day is their "net asset value" or "NAV."
This figure is computed by dividing total Fund assets, less any liabilities, by
the number of Fund shares outstanding. The net asset value per share of the Fund
is determined on each day both the Federal Reserve Bank of New York and the New
York Stock Exchange (the "Exchange") are open for business as of 4:00 p.m.
Eastern time. While the Fund attempts to maintain its net asset value at a
constant $1.00 per share, Fund shares are not insured against a reduction in net
asset value.
 
The Fund values its portfolio securities at amortized cost, which means that
they are valued at their acquisition cost (as adjusted for amortization of
premium or discount) rather than at current market value. Calculations are made
to compare the value of the Fund's investments using the amortized cost method
with market values. Market valuations are obtained by using actual quotations
provided by market makers, estimates of market value, or values obtained from
yield data relating to comparable classes of money market instruments published
by reputable sources at the mean between the bid and asked prices for the
instruments. If a deviation of 1/2 of 1% or more were to occur between the
Fund's net asset value per share calculated by reference to market values and
the Fund's $1.00 per share amortized cost value, or if there were any other
deviation which the Board of Trustees believed would result in a material
dilution to shareholders or purchases, the Board of Trustees would promptly
consider what action, if any, should be initiated.
 
HOW THE FUND SHOWS PERFORMANCE
 
From time to time the Fund may advertise its yield and effective yield.
Performance figures are based upon historical results and are not intended to
indicate future performance.
 
   
The yield of a Fund refers to the income generated by a hypothetical investment
in the Fund over a specific 7-day period. This income is then annualized, which
means that the income generated during the 7-day period is assumed to be
generated each week over an annual period and is shown as a percentage of the
hypothetical investment.
    
 
Effective yield is calculated similarly, but the income earned by the investment
is assumed to be compounded weekly when annualized. The effective yield will be
slightly higher than the yield due to this compounding effect. (See "Yield" in
the Statement of Additional Information.)
 
The performance of the Fund may be compared to that of other mutual funds
tracked by mutual fund rating services, various indices of investment
performance, United States government obligations,
 
                                       10
<PAGE>   79
 
bank certificates of deposit, other investments for which reliable performance
data is available and the consumer price index.
 
   
Additional performance information about the Fund is available in the Fund's
Annual Report, which is sent to all shareholders. To request a free copy, call
your local Schwab offices or 800-2 NO-LOAD.
    
 
GENERAL INFORMATION
 
   
The Schwab Fund Family was organized as a business trust under the laws of
Massachusetts on October 20, 1989 and may issue an unlimited number of shares of
beneficial interest in one or more investment portfolios or series ("Series").
Currently, shares of nine Series are offered. The Board of Trustees may
authorize the issuance of shares of additional Series if deemed desirable.
Shares of each Series have equal, non cumulative voting rights and equal rights
as to dividends, assets, and liquidation of such Series.
    
 
The Schwab Fund Family is not required to hold annual shareholders' meetings and
does not intend to do so. It will, however, hold special meetings as required or
deemed desirable by the Board of Trustees for such purposes as electing
trustees, changing fundamental policies or approving an investment advisory
agreement. Shareholders will vote by Series and not in the aggregate (for
example, when voting to approve the investment advisory agreement), except when
voting in the aggregate is permitted under the 1940 Act, such as for the
election of Trustees.
 
SHAREHOLDER GUIDE
--------------------------------------------------------------------------------
SCHWAB'S OFFICES ACCEPT ORDERS AND PROVIDE SHAREHOLDER SERVICE AND INFORMATION.
--------------------------------------------------------------------------------
 
SHAREHOLDER SERVICE. You may place Fund purchase and redemption orders as well
as request exchanges by calling your Schwab representative, who is available to
answer questions about the Fund and your account. The privilege to initiate
transactions by telephone, as discussed below, is automatically available
through your Schwab account. The Fund will employ reasonable procedures to
confirm that instructions communicated by telephone are genuine. If these
procedures are not followed, the Fund may be liable for any losses due to
unauthorized or fraudulent instructions. These procedures may include requiring
a form of personal identification prior to acting upon instructions received by
telephone, providing written confirmation of such instructions and tape
recording telephone transactions.
 
HOW TO PURCHASE SHARES
 
You may purchase shares of the Fund through an account maintained with Schwab or
The Charles Schwab Trust Company, and payment for shares must be made directly
to Schwab or The Charles Schwab Trust Company.
 
   
The minimum initial investment is $25,000, and subsequent investments must be at
least $1. Due to the relatively high cost of maintaining smaller holdings, the
Fund reserves the right to redeem a shareholder's shares if, as a result of
redemptions, their aggregate value drops below the Fund's $25,000 minimum
balance requirement. The Fund will notify shareholders in writing 30 days before
taking such action to allow them to increase their holding to at least the
minimum level.
    
 
                                       11
<PAGE>   80
 
You may deposit funds into your account by check or wire. All deposit checks
should be made payable to Charles Schwab & Co., Inc. or The Charles Schwab Trust
Company. If you would like to wire funds into your account, please contact your
Schwab Representative for instructions.
 
   
WHEN AND AT WHAT PRICE SHARES WILL BE PURCHASED. You must have funds in your
account maintained with Schwab or The Charles Schwab Trust Company in order to
purchase Fund shares. If funds (including those transmitted by wire) are
received by Schwab or The Charles Schwab Trust Company before 4:00 p.m. (Eastern
time), they will be available for investment on the day of receipt and will
generally begin earning dividends the next business day. If funds arrive after
that time, they will be available for investment the next Business Day. Orders
to purchase shares will be executed at the next determined net asset value after
receipt by Schwab's Mutual Fund Transfer Agent Department. (See "Share Price
Calculation.")
    
 
Customers with $100,000 or more to invest may, upon special request, be invested
in the Fund and receive a dividend for the day on which the order is received by
the Transfer Agent. This request must be received by Schwab or The Charles
Schwab Trust Company before 1:30 p.m. Eastern time and must be accompanied by
payment in immediately available funds.
 
AUTOMATIC REINVESTMENT. Distributions will be reinvested in additional full and
fractional shares of the Fund at the net asset value next determined on their
payable date.
 
OTHER PURCHASE INFORMATION. The Fund reserves the right, in its sole discretion
and without prior notice to shareholders, to withdraw or suspend all or any part
of the offering made by this Prospectus, to reject purchase orders or to change
the minimum investment requirements. All orders to purchase shares of the Fund
are subject to acceptance by the Fund and are not binding until confirmed or
accepted in writing. Schwab will charge a $15 service fee against an investor's
account should his or her check be returned because of insufficient or
uncollected funds or a stop payment order.
 
   
HOW TO EXCHANGE SHARES
    
------------------------------------------------------------------
SHARES OF THE FUND MAY BE EXCHANGED FOR SHARES
   
OF OTHER FUNDS SPONSORED BY SCHWAB.
    
------------------------------------------------------------------
 
   
The exchange privilege allows you to exchange your investment in the Fund for
shares of other SchwabFunds(R) available to investors in your state if your
purchase meets that fund's eligibility requirements. Thus, you can conveniently
modify your investments if your goals or market conditions change. An exchange
will involve the redemption of Fund shares at the net asset value next
determined after receipt by Schwab's Mutual Fund Transfer Agency Department of
an exchange request, and the purchase of shares in another fund at the net asset
value of that fund next determined after sale of the Fund shares involved in the
exchange. An exchange will be treated as a sale of the shares for federal income
tax purposes. Note that you must meet the initial or subsequent minimum
investment requirements applicable to the shares you wish to receive in
exchange. Only investors who may purchase shares of the Fund may exchange shares
of other SchwabFunds for shares of the Fund. The Fund reserves the right on 60
days' written notice to modify, limit or terminate the exchange privilege.

        - the distribution option you select.
    
 
BY MAIL:
 
You may also request an exchange by writing Schwab at the address listed on the
Prospectus cover page.
 
To properly process your mailed exchange request, we will need a letter from you
which:
 
   
        - references your Schwab account number;
    
   
        - specifies that you would like to exchange shares from the Fund and the
          number of shares to be exchanged;

        - is signed by at least one of the registered Schwab account holders, in
          the exact form specified in the account.
    
 
HOW TO REDEEM SHARES
 
   
THE PRICE AT WHICH SHARES WILL BE REDEEMED. Shares will be redeemed at the net
asset value per share next determined after receipt by Schwab's Mutual Fund
Transfer Agency Department of proper redemption instructions, as set forth
below. Investors will receive dividends declared for the day on which orders to
redeem shares are executed.
    
 
METHODS OF REDEEMING SHARES. Shareholders may place redemption orders by
contacting their Schwab Representative by telephone, by mail or in person.
Investors should be aware that telephone redemptions may be difficult to
implement during periods of drastic economic or market changes. Shareholders who
experience difficulties in redeeming by telephone can utilize one of the just
mentioned alternatives to place their redemption orders.
 
   
Telephone redemption orders received prior to 4:00 p.m. Eastern time on any
Business Day, once they have been verified by the Transfer Agent, will be deemed
to have been received by Schwab's Mutual Fund Transfer Agency Department on that
day. All other telephone redemption orders will be

 
                                       13
<PAGE>   82
 
considered received by Schwab's Mutual Fund Transfer Agency Department on the
following Business Day.
    
 
   
The Fund may suspend redemption rights or postpone payments at times when
trading on the Exchange is restricted, the Exchange is closed for any reason
other than its customary weekend or holiday closings, emergency circumstances as
determined by the SEC exist, or for such other circumstances as the SEC may
permit. The Fund may also elect to invoke a seven day period for cash settlement
of individual redemption requests in excess of $250,000 or 1% of the Fund's net
assets, whichever is less.
    
 
OTHER IMPORTANT INFORMATION
 
CONSOLIDATED MAILINGS. In an effort to reduce the Fund's mailing costs, the Fund
consolidates shareholder mailings by household. This consolidation means that a
household having multiple accounts with the identical address of record will
receive a single package during each shareholder mailing. If you do not wish
this consolidation to apply to your account(s), please write to Schwab (at the
address listed on the Prospectus cover page) to that effect.
 
WIRE TRANSFERS TO YOUR BANK. If you so instruct your Schwab Representative,
funds can be wired from your account maintained with Schwab or The Charles
Schwab Trust Company to your bank account. Call your Schwab Representative for
additional information. A $15 service fee will be charged against your account
for each such wire sent.

KEY FEATURES OF THE FUND
 
TRIPLE TAX-EXEMPT INCOME AND SAFETY. The Schwab New York Tax-Exempt Money Fund
is designed for investors who seek maximum after-tax current income consistent
with liquidity and stability of capital. The Fund primarily invests in high
quality, short-term debt securities the interest on which is exempt from federal
income taxes and personal income taxes imposed by New York State and New York
municipalities. The Fund attempts to maintain a stable net asset value of $1.00
per share. (See "Investment Objective and Policies.")
 
AUTOMATIC INVESTMENT/REDEMPTION FEATURE. For the Sweep Shares of the Fund, if
you elect, free credit balances in your Schwab brokerage account (including your
Schwab One(R) account) will be automatically invested or "swept" into the Fund,
subject to the terms and conditions of your brokerage account agreement. Shares
will also be sold as necessary to settle securities transactions, collateralize
margin obligations or cover debit balances. This feature keeps your money
working and saves you the time and trouble of withdrawing and redepositing
funds. (See "How to Purchase Shares" and "How to Redeem Shares.")
 
LIQUIDITY. You can conveniently place orders to redeem your investment in the
Fund at any time. (See "How to Redeem Shares.")
 
   
LOW COST INVESTING. The Fund imposes no sales or transaction fees on purchases

1 This amount reflects a reduction by the Investment Manager, which is
guaranteed through at least April 30, 1996. If there were no such reduction, the
maximum management fee for the Fund would be 0.46%. (See "Management of the
Fund--Fees and Expenses.")
    
 
2 See "Management of the Fund--Fees and Expenses" for information regarding the
differing expenses for the multiple classes of shares of the Fund.
 
   
3 Schwab currently imposes no fees for opening and maintaining a Schwab
brokerage account. Effective October 1, 1995, Schwab will institute a $1,000
minimum equity requirement for brokerage accounts ($500 for custodial accounts).
A quarterly fee of $7.50 will be charged on accounts that fall below the
minimum. This fee, if applicable, will be charged at the end of each quarter and
will be waived if there has been one commissionable trade within the last six
months, or if the shareholder's combined account balances at Schwab total
$10,000 or more. Schwab imposes no fees for opening and maintaining a Schwab
One(R) account with a minimum balance of $5,000. Schwab One accounts with
balances below $5,000 are subject to a monthly fee of $5 if there have been
fewer than two commissionable trades within the last 12 months. Schwab
Individual Retirement Accounts with balances of $10,000 or more by September 15,
1995 are not charged Schwab's $29 annual IRA account fee for the life of the
account. Schwab Keogh plans are currently charged an annual fee of $45. See "How
to Purchase Shares" for information regarding the differing minimum balance and
minimum investment requirements of the multiple classes of shares of the Fund.
    
 
   
4 This amount reflects the guarantee by Schwab and the Investment Manager that,
through at least April 30, 1996, the total operating expenses of the Sweep
Shares of the Fund will not exceed 0.69% of the Sweep Shares' average daily net
assets. Without this guarantee, it is estimated that total operating expenses
would be approximately 1.02%* of the Sweep Shares' average daily net assets.
    
 
EXAMPLE. You would pay the following expenses on a $1,000 investment in the
Sweep Shares of the Fund, assuming (1) a 5% annual return and (2) redemption at
the end of each period:

MATCHING THE FUND TO YOUR INVESTMENT NEEDS
 
   
The Fund may be appropriate for a variety of investment programs which can be
long-term or short-term in nature. While the Fund is not a substitute for
building an investment portfolio tailored to an individual's investment needs
and risk tolerance, it can be used as a high-quality, conveniently liquid money
market investment for your brokerage account cash when it is not fully invested
in other securities. The Fund would not be an appropriate investment for
retirement plans such as IRAs and Keogh plans.
    
-------------------------------------------------------------
THE FUND MAY BE ESPECIALLY SUITABLE FOR SHORT-TERM INVESTORS.
-------------------------------------------------------------
 
Because the Fund is designed to provide liquidity and stability of capital, as
well as automatic investment of free credit balances, it may be especially
suitable for investors with short-term investment objectives, including those
who are awaiting an opportune time to invest in the equity and/or bond markets.
---------------------------------------------------------
THE FUND MAY ALSO BE APPROPRIATE FOR LONG-TERM INVESTORS.
---------------------------------------------------------
 
The Fund may also be appropriate for long-term investors seeking a low-risk
investment alternative which is designed to provide income which is exempt from
federal income taxes and personal income taxes imposed by New York State and New
York municipalities.
 
In addition to the Sweep Shares of the Fund, Schwab also offers Value Advantage
Shares of the Fund, pursuant to a multiple class plan (the "Plan") adopted by
the Board of Trustees of the Schwab Fund Family. Under the Plan, Value Advantage
Shares of the Fund, which are not available through automatic ("sweep")
investment programs, are subject to lower transfer agency expenses than the
Sweep Shares of the Fund. In addition, the minimum investment and minimum
account balance requirements of the Value Advantage Shares of the Fund are
higher than those applicable to the Sweep Shares. See "Management of the
Fund--Fees and Expenses" and "How to Purchase Shares."
 
For information regarding Value Advantage Shares, call your local Schwab office
or 800-2 NO-LOAD. You may also obtain information about Value Advantage Shares
from your Schwab broker.
 
INVESTMENT OBJECTIVE AND POLICIES
--------------------------------------------------------------
THE FUND SEEKS MAXIMUM CURRENT INCOME CONSISTENT WITH
LIQUIDITY AND STABILITY OF CAPITAL THAT IS EXEMPT FROM FEDERAL
INCOME TAXES AND PERSONAL INCOME TAXES IMPOSED
BY NEW YORK STATE AND NEW YORK MUNICIPALITIES.
--------------------------------------------------------------
 
   
The investment objective of the Fund is maximum current income that is exempt
from federal income taxes and personal income taxes imposed by New York State
and New York municipalities, to the extent consistent with liquidity and
stability of capital. This investment objective is fundamental, and cannot be
changed without approval by holders of a majority of the Fund's outstanding
voting shares, as defined in the Investment Company Act of 1940 (the "1940
Act"). The Fund pursues its objective primarily by investing in short-term
high-quality municipal obligations, the income from which is

                                        5
<PAGE>   90
 
exempt from federal income taxes and personal income taxes imposed by New York
State and New York municipalities.
     
Under normal market conditions, the Fund attempts to invest 100%, and will
invest at least 80%, of its total assets in debt obligations issued by or on
behalf of New York and other states, territories and possessions of the United
States (including the District of Columbia) and their political subdivisions,
agencies and instrumentalities that generate interest which, in the opinion of
bond counsel, is exempt from federal income taxes ("Municipal Securities").
Absent unusual market conditions, the Fund will invest at least 65% of its total
assets in such obligations which also generate interest which, in the opinion of
bond counsel, is exempt from State of New York and New York municipal personal
income tax ("New York Municipal Securities"). Under normal market conditions,
the Fund is authorized to invest up to 20% of its total assets in "private
activity bonds." (See "Distributions and Taxes--Federal Income Taxes.") The
Fund's investment in private activity bonds will not be included in the amount
deemed to be invested in New York Municipal Securities.
 
Provided that certain minimum conditions are met, dividends paid to New York
residents consisting of interest income received on New York Municipal
Securities will be exempt from State of New York personal income taxes.
-------------------------------------------------
THE FUND ONLY INVESTS IN HIGH QUALITY SECURITIES.
-------------------------------------------------
 
The Fund invests only in Municipal Securities which at the time of purchase: (a)
are rated in one of the two highest rating categories for municipal commercial
paper or short-term municipal securities assigned by Moody's Investors Service,
Standard & Poor's Corporation or any other nationally recognized statistical
rating organization ("NRSRO"); (b) are guaranteed or insured by the U.S.
Government as to the payment of principal and interest; (c) are fully
collateralized by an escrow of U.S. Government securities acceptable to the
Investment Manager; or (d) are unrated by any NRSRO, if they are determined by
the Investment Manager, using guidelines approved by the Board of Trustees, to
be at least equal in quality to one or more of the above referenced securities.
(For a description of the ratings, see "Appendix--Ratings of Investment
Securities" in the Statement of Additional Information.)
 
After its purchase by the Fund, a Municipal Security may cease to be rated or
its rating may be reduced below that required for purchase by the Fund. Neither
event would necessarily require the elimination of such an obligation from the
Fund's investment portfolio. However, the obligation generally would be retained
only if such retention was determined by the Board of Trustees to be in the best
interests of the Fund.
 
With the exception of securities issued or guaranteed by the U.S. Government,
its agencies and instrumentalities, the Fund may not:
 
1. Purchase the securities of any issuer if as a result more than 5% of the
   value of the Fund's total assets would be invested in the securities of that
   issuer. However, provided that no more than 25% of the value of the Fund's
   total assets are invested in the securities of any one issuer, up to 50% of
   the value of the Fund's total assets may be invested without regard to this
   5% limitation. For
 
                                        6
<PAGE>   91
 
   purposes of this limitation, a security is considered to be issued by the
   governmental entity (or entities) whose assets and revenues back the
   security, or, with respect to a private activity or an industrial revenue
   bond that is backed only by the assets and revenues of a non-governmental
   user, by such non-governmental user. In certain circumstances, the guarantor
   of a security may also be considered to be an issuer in connection with such
   guarantee.
 
2. Purchase any securities which would cause 25% or more of the value of the
   Fund's total assets at the time of purchase to be invested in the securities
   of issuers conducting their principal business activities in the same
   industry. However, this limitation shall not apply to Municipal Securities
   issued by governmental entities.
 
From time to time, as a defensive measure under abnormal market conditions, the
Fund may invest any or all of its assets in taxable "temporary investments"
which include: obligations of the U.S. Government, its agencies or
instrumentalities; debt securities rated (other than Municipal Securities) in
one of the two highest categories by any NRSRO; commercial paper (other than
Municipal Securities) rated in one of the two highest rating categories by any
NRSRO; certificates of deposit of domestic banks having capital, surplus, and
undivided profits in excess of $100 million; and any of the foregoing temporary
investments subject to repurchase agreements. While purchases by the Fund of
certain temporary investments could cause it to generate dividends taxable to
shareholders as ordinary income (see "Distributions And Taxes"), it is the
Fund's primary intention to produce dividends which are not subject to federal
income or New York personal income taxes.
 
The investment policies set forth above (except for the policy regarding
temporary investments, or as otherwise noted) are fundamental. They, along with
certain investment restrictions adopted by the Fund (see "Investment
Restrictions" in the Statement of Additional Information), cannot be changed
without approval by holders of a majority of the Fund's outstanding voting
shares, as defined in the 1940 Act.
 
MUNICIPAL SECURITIES AND INVESTMENT TECHNIQUES
 
The two principal classifications of Municipal Securities which may be held by
the Fund are "general obligation" securities and "revenue" securities. General
obligation securities are secured by the issuer's pledge of its full faith,
credit and taxing power for the payment of principal and interest. Revenue
securities 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
tax or other specific revenue source such as the user of the facility being
financed. Revenue securities may include private activity bonds (and industrial
development bonds). Such bonds may be issued by or on behalf of public
authorities to finance various privately operated facilities, and are not
payable from the unrestricted revenues of the issuer. As a result, the credit
quality of private activity bonds is frequently related directly to the credit
standing of private corporations or other entities. From time to time, the Fund
may invest more than 25% of its total assets in industrial development and
private activity bonds.
 
The Fund's portfolio may also include "moral obligation" securities, which are
normally issued by special purpose public authorities. If the issuer of moral
obligation securities is unable to meet its debt
 
                                        7
<PAGE>   92
 
service obligations from current revenues, it may draw on a reserve fund, the
restoration of which is a moral commitment but not a legal obligation of the
state or municipality which created the issuer.
 
Municipal Securities purchased by the Fund may include variable rate demand
instruments issued by industrial development authorities and other government
entities. In the event variable rate demand instruments which the Fund can
purchase are not rated by credit rating agencies, such instruments must be
determined by the Investment Manager, using guidelines approved by the Board of
Trustees, to be of comparable quality at the time of purchase to rated
instruments which the Fund can purchase. In some cases, the Fund may require
that the issuer's obligation to pay the principal of the note be backed by an
unconditional bank letter or line of credit, guarantee or commitment to lend.
Although there may be no active secondary market with respect to a particular
variable rate demand instrument purchased by the Fund, the Fund may (at any time
or during specified periods not exceeding one year, depending upon the
instrument involved) demand payment in full of the principal of the instrument
and may resell the instrument to a third party. The absence of such an active
secondary market, however, could make it difficult for the Fund to dispose of a
variable rate demand instrument in the event the issuer defaulted on its payment
obligation or during periods that the Fund is not entitled to exercise its
demand rights, and the Fund could, for this or other reasons, suffer a loss with
respect to such instruments. To the extent that the absence of an active
secondary market for such securities causes them to be "illiquid," such
securities will be subject to the Fund's restrictions on acquiring and holding
illiquid securities.
 
Participation interests in Municipal Securities with fixed, floating or variable
rates of interest may be purchased by the Fund from financial institutions. The
buyer of a participation interest receives an undivided interest in the
securities underlying the instrument. The Fund will only purchase a
participation interest if: (a) the Municipal Securities subject to it mature in
one year or less or the instrument includes a right to demand payment, usually
within seven days, from the Seller, (b) the instrument meets the Fund's
previously described quality standards for Municipal Securities, and (c) the
instrument is issued with an opinion of counsel or is the subject of a ruling of
the Internal Revenue Service, stating that the interest earned on the
participation interest is exempt from federal income tax.
 
The Fund may purchase securities on a "when-issued" or "delayed delivery" basis.
When-issued or delayed delivery securities are securities purchased for future
delivery at a stated price and yield. The Fund will generally not pay for such
securities or start earning interest on them until they are received. Securities
purchased on a when-issued or delayed delivery basis are recorded as an asset
and are subject to changes in value based upon changes in the general level of
interest rates. The Fund will not invest more than 25% of its assets in
when-issued or delayed delivery securities, does not intend to purchase such
securities for speculative purposes and will make commitments to purchase
securities on a when-issued or delayed delivery basis with the intention of
actually acquiring the securities. However, the Fund reserves the right to sell
acquired when-issued or delayed delivery securities before their settlement
dates if deemed advisable.
 
The Fund may invest in municipal leases, which are obligations issued by state
and local governments or authorities to finance the acquisition of equipment and
facilities. These obligations may take the
 
                                        8
<PAGE>   93
 
form of a lease, an installment purchase contract, a conditional sales contract,
or a participation interest in any of the above. Investments in municipal leases
may be considered to be illiquid. The Fund will limit its investment in
municipal leases to no more than 25% of its total assets (no more than 10% of
which may be illiquid municipal leases). Municipal leases are subject to
"nonappropriation risk," which is the risk that the municipality may terminate
the lease in the event that the municipality's appropriating body does not
allocate the funds necessary to make lease payments. In such circumstances, the
lessor is typically entitled to repossess the property. The private sector value
of the property is, however, generally less than the value of the property to
the municipality. The Investment Manager, pursuant to guidelines established by
the Board of Trustees, is responsible for determining the credit quality of
unrated municipal leases, on an ongoing basis, including an assessment of the
likelihood of whether the lease will be terminated.
 
   
The Fund may also invest up to 25% of its assets in synthetic variable or
floating rate municipal securities. These securities generally comprise the
following elements in a trust: (i) a fixed-rate municipal bond (of any
duration); (ii) a right to put the bond at par value on 7-days notice or after a
specific interval of time depending on the terms of the synthetic security; and
(iii) a contractual agreement pursuant to which the investing Fund and the
issuer determine the lowest rate that would permit the bond to be remarketed at
par, taking into account the put right. The trustee of the trust is generally a
bank trust department.
    
 
   
These securities may include tender option bond trust receipts, in which a
fixed-rate municipal bond (or group of bonds) is placed into a trust from which
two classes of trust receipts are issued, which represent proportionate
interests in the underlying bond(s). Interest payments are made on the bond(s)
based upon a pre-determined rate. Under certain circumstances, the holder of a
trust receipt may also participate in any gain or loss on the sale of such
bond(s). Tender option bond trust receipts generally are structured as private
placements and, accordingly, may be deemed to be restricted securities for
purposes of the Fund's investment limitations. Tender option bond trust receipts
are considered to be Municipal Securities for purposes of the Fund's policy to
invest at least 80% of its total assets in Municipal Securities.
    

The Fund may also acquire "stand-by commitments" with respect to Municipal
Securities held in its portfolio. Under a stand-by commitment, a dealer agrees
to purchase at the Fund's option specified Municipal Securities at a price equal
to their amortized cost value plus accrued interest. The Fund will acquire
stand-by commitments solely to facilitate portfolio liquidity and does not
intend to exercise its rights thereunder solely for trading purposes.
 
The Fund may engage in "repurchase agreements." In entering into a repurchase
agreement, the Fund acquires ownership of a security from a broker-dealer or
bank that agrees to repurchase the security at a mutually agreed upon time and
price (which price is higher than the purchase price), thereby determining the
yield during the Fund's holding period. Repurchase agreements with broker-dealer
firms will be limited to obligations of the U.S. Government, its agencies or
instrumentalities. Maturity of the securities subject to repurchase may exceed
one year.

    
As a matter of fundamental policy, the Fund may borrow money for temporary
purposes, but not for the purpose of purchasing investments, in an amount up to
one-third of the value of the Fund's total
 
                                        9
<PAGE>   94
assets and may pledge up to 10% of the Fund's net assets to secure borrowings.
The Fund will not purchase illiquid securities, including repurchase agreements
maturing in more than 7-days, if, as a result thereof, more than 10% of the
Fund's net assets valued at the time of the transaction would be invested in
such securities.
    
 
Opinions relating to the validity of Municipal Securities and to the exemption
of interest thereon from federal income tax (and, with respect to New York
Municipal Securities, to the exemption of interest thereon from New York State
and New York municipalities personal income taxes) are rendered by bond counsel
to the respective issuers at the time of issuance. The Fund and the Investment
Manager will not review the proceedings relating to the issuance of Municipal
Securities or the bases for such opinions.
 
SPECIAL RISK CONSIDERATIONS. The Fund intends to follow the diversification
standards set forth in the 1940 Act, except to the extent that, in the
Investment Manager's judgment, non-diversification is appropriate to maximize
the percentage of the Fund's assets that are New York Municipal Securities. The
investment return on a non-diversified portfolio typically is dependent upon the
performance of a smaller number of issuers relative to the number of issuers
held in a diversified portfolio. In the event of changes in the financial
condition or in the market's assessment of certain issuers, the Fund's policy of
acquiring large positions in the obligations of a relatively small number of
issuers may affect the value of the Fund's portfolio to a greater extent than it
would that of a diversified portfolio.
 
Although the Fund does not presently intend to do so on a regular basis, it may
invest more than 25% of its assets in Municipal Securities the interest on which
is paid solely from revenues on similar projects if such investment is deemed
necessary or appropriate by the Investment Manager. To the extent that the
Fund's assets are concentrated in Municipal Securities payable from revenues on
similar projects, the Fund will be subject to the particular risks presented by
such projects to a greater extent than it would be if the Fund's assets were not
so concentrated.
 
Certain New York constitutional amendments, legislative measures, executive
orders, administrative regulations and voter initiatives could result in adverse
consequences affecting New York Municipal Securities. (See "Municipal
Securities" in the Statement of Additional Information for more information
about these significant financial considerations.)
 
Participation interests in Municipal Securities and other derivative securities
eligible for purchase by the Fund involve special risks, including a risk that
the Internal Revenue Service may characterize some or all of the interest paid
on such securities to the Fund as taxable. There is also an increased risk, most
typically associated with "municipal lease" obligations, that a municipality
will not appropriate the funds necessary to make the scheduled payments on, or
may seek to cancel or otherwise avoid its obligations under, the lease that
supports the security owned by the Fund.
 
MANAGEMENT OF THE FUND
 
   
Responsibility for overall management of the Fund rests with the trustees and
officers of the Schwab Fund Family. Professional investment management for the
Fund is provided by the Investment Manager, Charles Schwab Investment
Management, Inc., 101 Montgomery Street, San Francisco, CA 94104. The Investment
Manager provides a continuous investment program, including general
 
                                       10
<PAGE>   95

investment and economic advice regarding the Fund's investment strategies,
manages the Fund's investment portfolio and performs expense management,
accounting and record keeping, and other services necessary to the operation of
the Fund and the Schwab Fund Family. The Investment Manager, formed in 1989, is
a wholly-owned subsidiary of The Charles Schwab Corporation and is the
investment adviser and administrator of the SchwabFunds(R) mutual funds. As of
July 31, 1995, the SchwabFunds had aggregate net assets in excess of $28
billion.
    
 
Charles Schwab & Co., Inc. ("Schwab" or the "Transfer Agent"), 101 Montgomery
Street, San Francisco, CA 94104, serves as shareholder services agent and
transfer agent for the Fund. Schwab provides information and services to
shareholders, which include reporting share ownership, sales and dividend
activity (and associated tax consequences), responding to daily inquiries,
effecting the transfer of Fund shares and facilitating effective cash management
of shareholders' Schwab account balances. It furnishes office space and
equipment, telephone facilities, personnel and informational literature
distribution as is necessary or appropriate in providing shareholder and
transfer agency information and services. Schwab is also the Fund's distributor,
but receives no compensation for its services as such.
 
   
Schwab was established in 1971 and is one of America's largest discount brokers.
The firm provides low-cost securities brokerage and related financial services
to over 2.5 million active customer accounts and has over 200 offices. Schwab
also offers convenient access to financial information services and provides
products and services that help investors make investment decisions. Schwab is a
wholly-owned subsidiary of The Charles Schwab Corporation. Charles R. Schwab is
the founder, Chairman, Chief Executive Officer and a director of The Charles
Schwab Corporation and, as of July 31, 1995, the beneficial owner of
approximately 20.5% of the outstanding shares of that corporation. Mr. Schwab
may be deemed to be a controlling person of Schwab and the Investment Manager.
    
 
   
FEES AND EXPENSES. Pursuant to its Investment Advisory and Administration
Agreement with the Schwab Fund Family, the Investment Manager receives from the
Fund a graduated annual fee, payable monthly, of 0.46% of the Fund's average
daily net assets not in excess of $1 billion, 0.41% of such net assets over $1
billion but not in excess of $2 billion and 0.40% of such net assets over $2
billion. The Investment Manager may reduce its management fee from time to time
in the future. Fee reductions lower the Fund's expenses and thus increase the
total return it provides shareholders. At least through April 30, 1996, the
Investment Manager guarantees that the Fund's management fee will not exceed
0.20% of the Fund's average daily net assets. In addition, the Investment
Manager and Schwab guarantee that total operating expenses will not exceed 0.69%
of the average daily net assets of the Sweep Shares. Interest expenses, taxes
and capital items such as, but not limited to, costs incurred in connection with
the purchase or sale of portfolio securities, including brokerage fees or
commissions, are not included as operating expenses for the purpose of this
guarantee. The effect of these guarantees is to maintain or lower expenses of
the Sweep Shares and thus maintain or increase the total return to shareholders.
Without this guarantee, it is estimated that total annualized operating expenses
of the Sweep Shares would be approximately 1.02% of its average daily net
assets.
    
 
                                       11
<PAGE>   96
 
For the transfer agency services provided, the Transfer Agent receives an annual
fee, payable monthly, of 0.25% of the average daily net assets of the Sweep
Shares. In addition, for shareholder services provided, Schwab receives an
annual fee, payable monthly, of 0.20% of the average daily net assets of the
Sweep Shares. For the Value Advantage Shares, the Transfer Agent receives an
annual fee of 0.05% of the average daily net assets of that class' shares of
beneficial interest. PNC Bank is the Fund's Custodian.
 
   
The Schwab Fund Family pays the expenses of its operations, including the fees
and expenses of independent accountants, counsel and custodian, and the costs of
calculating net asset values, brokerage commissions or transaction costs, taxes,
registration fees, and the fees and expenses of qualifying the Schwab Fund
Family and its shares for distribution. These expenses are generally allocated
among the Schwab Fund Family's investment portfolios ("Series") on the basis of
relative net assets at the time of allocation. However, expenses directly
attributable to a particular Series or class of a Series are charged to that
Series or class, respectively. The differing expenses applicable to the Sweep
Shares and the Value Advantage Shares will cause the performance of the two
classes of shares of the Fund to differ.
    
 
DISTRIBUTIONS AND TAXES
---------------------------------------------------------
THE FUND DECLARES DAILY DIVIDENDS WHICH ARE PAID MONTHLY.
---------------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS. On each day that the net asset value per
share of the Fund is determined ("Business Day"), the Fund's net investment
income will be declared as of the close of trading on the New York Stock
Exchange (the "Exchange") (generally 4:00 p.m. Eastern time) as a dividend to
shareholders already of record at the previous net asset value calculation.
Dividends are normally paid (and, where applicable, reinvested) on the 15th of
each month, if a Business Day, otherwise on the next Business Day.
 
   
TAX INFORMATION. The Fund intends to be treated as a regulated investment
company under the Internal Revenue Code of 1986, as amended (the "Code") and
applicable state laws. In order to so qualify, the Fund will distribute on a
current basis substantially all of its investment company taxable income, its
net exempt-interest income and its net capital gains (if any), and will meet
certain other requirements. Such qualification relieves the Fund of liability
for federal and New York income taxes to the extent the Fund's earnings are
distributed.
    
 
   
FEDERAL INCOME TAXES. Dividends derived from exempt-interest on state and local
obligations and designated by the Fund as "exempt-interest dividends" may be
treated by the Fund's shareholders as items of interest excludable from their
federal gross income. A shareholder should consult his or her own tax adviser
with respect to whether exempt-interest dividends would be excludable from gross
income if the shareholder were treated as a "substantial user" of facilities
financed by an obligation held by the Fund or a "related person" to such user
under the Code. Any loss on the sale or exchange of any share held for six
months or less will be disallowed to the extent of the amount of the exempt-
interest dividend received with respect to such share. The U.S. Treasury
Department is authorized to issue regulations reducing the period to not less
than 31 days for certain regulated investment companies, but no such regulations
have been issued as of the date of this Prospectus. To the extent
 
                                       12
<PAGE>   97
 
dividends paid to shareholders are derived from taxable interest or short-term
or long-term capital gains, such dividends will be subject to federal income tax
whether paid in the form of cash or additional shares. Fund dividends derived
from interest on U.S. Treasury and agency obligations are subject to federal
income tax.
    
 
The Fund may at times purchase Municipal Securities or New York Municipal
Securities at a discount from the price at which they were initially issued. For
federal income tax purposes, some or all of this market discount will be
included in the Fund's ordinary income and will be taxable to shareholders as
such when it is distributed to them.
 
If the Fund holds certain "private activity bonds" ("industrial development
bonds" under prior law), dividends derived from interest on such obligations
will be classified as an item of tax preference which could subject certain
shareholders to federal alternative minimum tax liability. Corporate
shareholders must also take all exempt-interest dividends into account in
determining "adjusted current earnings" for purposes of calculating their
alternative minimum tax.
 
Private activity bonds and industrial development bonds generally are bonds
issued by or on behalf of public authorities to obtain funds to provide certain
privately owned or operated facilities. Private activity bonds and industrial
development bonds also are generally limited obligation (or revenue) securities,
which means that they are payable only from the revenues derived from a
particular facility or class of facilities, or, in some cases, from some other
specific revenue source. (See "Municipal Securities" in the Statement of
Additional Information.)
 
Reinvested distributions will be taxable as if they had been received by
shareholders in cash. It is not expected that any portion of the dividends paid
by the Fund will be eligible for the corporate dividends received deduction.
Shareholders should note that all exempt-interest dividends will be taken into
account in determining the taxability of Social Security benefits or Railroad
Retirement Act benefits. (See "Distributions and Taxes" in the Statement of
Additional Information.)
 
NEW YORK INCOME TAXES: Dividends paid by the Fund to non-corporate shareholders
and derived from interest on New York Municipal Securities or federal
obligations are also exempt from State of New York personal income tax. For this
purpose, federal obligations are obligations the interest on which is excludable
from gross income for state income tax purposes under the Constitution or laws
of the United States. However, dividends paid to shareholders that are
corporations subject to New York franchise tax or corporate income tax will be
taxed as ordinary income to such shareholders, notwithstanding that all or a
portion of such dividends are exempt from State of New York personal income tax.
Moreover, to the extent that the Fund's dividends are derived from interest on
debt obligations other than New York Municipal Securities or federal
obligations, such dividends will be subject to State of New York personal income
tax, even though such dividends may be exempt for federal income tax purposes.
 
To the extent, if any, that dividends paid to shareholders are derived from
taxable interest or from long-term or short-term capital gains, such dividends
will not be exempt from New York personal income tax whether received in cash or
reinvested in shares.
 
                                       13
<PAGE>   98
 
   
Records of dividends and other distributions, purchases and redemptions will be
reflected on shareholders' regular Schwab statements. The Fund will notify
shareholders at least annually as to the federal income and State of New York
personal income tax consequences of distributions made each year.
    
 
The foregoing is only a brief summary of some of the federal and New York income
tax considerations affecting the Fund and its shareholders. (See the Trust's
Statement of Additional Information for more information.) Potential investors
should consult their tax advisers with specific reference to their own tax
situations.
 
SHARE PRICE CALCULATION
-------------------------------------------------
THERE ARE NO SALES CHARGES OR TRANSACTION FEES TO
PURCHASE OR REDEEM SHARES OF THE FUND.
-------------------------------------------------
 
   
The price of a Sweep Share of the Fund on any given day is its "net asset value"
per share or "NAV." This figure is computed by dividing total Fund assets
allocable to that class, less any liabilities allocable to the class, by the
number of shares of the class outstanding. The net asset value per share of the
Sweep Shares of the Fund is determined on each day both the Federal Reserve Bank
of New York and the Exchange are open for business, first at 10:00 a.m. (Eastern
time), then again as of the close of normal trading on the Exchange (generally
4:00 p.m. Eastern time). Purchase or redemption orders and exchange requests
will be executed at the net asset value next determined after receipt by
Schwab's Mutual Fund Transfer Agency Department. While the Fund attempts to
maintain its net asset value at a constant $1.00 per share, Fund shares are not
insured against reduction in net asset value.
    
 
The Fund values its portfolio securities at amortized cost, which means that
they are valued at their acquisition cost (as adjusted for amortization of
premium or discount) rather than at current market value. Calculations are made
to compare the value of the Fund's investments using the amortized cost method
with market values. Market valuations are obtained by using actual quotations
provided by market makers, estimates of market value, or values obtained from
yield data relating to classes of money market instruments published by
reputable sources at the mean between the bid and asked prices for the
instruments. If a deviation of 1/2 of 1% or more were to occur between the net
asset value per share of the Sweep Shares of the Fund calculated by reference to
market values and the $1.00 per share amortized cost value of the Sweep Shares
of the Fund, or if there were any other deviation which the Board of Trustees
believed would result in a material dilution to shareholders or purchasers, the
Board of Trustees would promptly consider what action, if any, should be
initiated.
 
HOW THE FUND SHOWS PERFORMANCE
 
   
From time to time the Fund may advertise the yield, effective yield, taxable
equivalent yield and taxable equivalent effective yield of the Sweep Shares of
the Fund. Performance figures are based upon historical results and are not
intended to indicate future performance.
    
 
The yield of the Sweep Shares of the Fund refers to the income generated by a
hypothetical investment in Sweep Shares of the Fund over a specific 7-day
period. This income is then annualized,
 
                                       14
<PAGE>   99
 
which means that the income generated during the 7-day period is assumed to be
generated each week over an annual period and is shown as a percentage of the
hypothetical investment.
 
Effective yield is calculated similarly, but the income earned by the investment
is assumed to be compounded weekly when annualized. The effective yield will be
slightly higher than the yield due to this compounding effect.
 
   
Taxable equivalent yield is the yield that a taxable investment must generate in
order to equal (after applicable taxes are deducted) the Sweep Share's yield for
an investor in stated federal, State of New York, and New York Municipal income
tax brackets (normally assumed to be the applicable maximum tax rate). Taxable
equivalent yield is based upon, and will be higher than, the portion of the
Sweep Share's yield that is tax-exempt. (See "Yield" in the Statement of
Additional Information.)
    
 
   
The taxable equivalent effective yield is computed in the same manner as is the
taxable equivalent yield, except that the effective yield is substituted for
yield in the calculation.
    
 
The performance of the Sweep Shares of the Fund may be compared to that of other
mutual funds tracked by mutual fund rating services, various indices of
investment performance, United States government obligations, bank certificates
of deposit, other investments for which reliable performance data is available
and the consumer price index.
 
Because the Sweep Shares of the Fund are subject to different expenses than the
Value Advantage Shares, the performance of the two classes of shares will
differ.
 
Additional performance information about the Sweep Shares of the Fund is
available in the Fund's Annual Report, which is sent to all shareholders. To
request a free copy, call your local Schwab office at 800-2 NO-LOAD.
 
GENERAL INFORMATION
 
   
The Schwab Fund Family was organized as a business trust under the laws of
Massachusetts on October 20, 1989 and may issue an unlimited number of shares of
beneficial interest or classes of shares in one or more Series. Currently, the
Schwab Fund Family offers shares of nine Series which may be organized into one
or more classes of shares of beneficial interest. The Board of Trustees may
authorize the issuance of shares of additional Series or classes if it deems it
desirable to do so. Shares of each class or Series have equal noncumulative
voting rights and equal rights as to dividends, assets, and liquidation of such
Series, except to the extent such voting rights or rights as to dividends,
assets, and liquidation vary among classes of a Series.
    
 
The Schwab Fund Family is not required to hold annual shareholders' meetings. It
will, however, hold special meetings as required or deemed desirable by the
Board of Trustees for such purposes as electing trustees, changing fundamental
policies, or approving an investment advisory or sub-advisory agreement. In
addition, a Trustee may be elected or removed by shareholders at a special
meeting called upon written request of shareholders owning at least 10% of the
outstanding shares of the Schwab Fund Family. Shareholders will vote by Series
and not in the aggregate (for example, when voting to approve the investment
advisory agreement), except when voting in the aggregate is permitted under the
1940 Act, such as for the election of Trustees. In addition, holders of the
Sweep
 
                                       15
<PAGE>   100
 
Shares will vote exclusively as a class on any matter relating solely to the
Sweep Shares' arrangement as a class and on any matter in which the interests of
the holders of the Sweep Shares differ from the interests of the holders of
Value Advantage Shares.
 
SHAREHOLDER GUIDE
------------------------------------------
SCHWAB'S OFFICES ACCEPT ORDERS AND PROVIDE
SHAREHOLDER SERVICE INFORMATION.
------------------------------------------
 
   
SHAREHOLDER SERVICE. You may place Fund purchase and redemption orders as well
as request exchanges at any one of over 200 Schwab offices nationwide or by
calling 800-2 NO-LOAD, where trained representatives are available to answer
questions about the Fund and your account. The privilege to initiate
transactions by telephone, as discussed below, is automatically available
through your Schwab account. The Fund will employ reasonable procedures to
confirm that instructions communicated by telephone are genuine. If these
procedures are not followed, the Fund may be liable for any losses due to
unauthorized or fraudulent instructions. These procedures may include requiring
a form of personal identification prior to acting upon instructions received by
telephone, providing written confirmation of such instructions and tape
recording telephone transactions. Investors should be aware that telephone
redemption may be difficult to implement during periods of drastic economic or
market changes. Shareholders who experience difficulties in purchasing,
redeeming or exchanging shares by telephone can utilize the alternative methods
discussed below to place their orders.
    
 
   
Telephone purchase or redemption orders and exchange requests received prior to
6:00 p.m. (Eastern time) on any Business Day, once they have been verified as to
the caller's identity and account ownership, will be deemed to be received by
Schwab's Mutual Fund Transfer Agency Department prior to the next net asset
value determination. All subsequent telephone redemption orders received prior
to the first net asset value determination on the following day will be deemed
received prior to that day's second net asset value determination.
    
 
HOW TO PURCHASE SHARES
--------------------------------------------------
YOU MAY PURCHASE SHARES OF THE FUND ONLY THROUGH A
SCHWAB ACCOUNT.
--------------------------------------------------
 
   
You may purchase shares of the Fund exclusively through an account maintained
with Schwab, and payment for shares must be made directly to Schwab. Certain
fees may be charged to Schwab accounts which do not maintain required minimum
balances. (See "Summary of Expenses" for more information.) The Securities
Investor Protection Corporation ("SIPC") will provide account protection, in an
amount up to $500,000, for securities, including Fund shares which you hold in a
Schwab account. Of course, SIPC account protection does not protect shareholders
from share price fluctuations.
    
 
   
If you already have a Schwab account, you may purchase shares in the Fund as
described below and need not open a new account.
    
 
                                       16
<PAGE>   101
 
   
If you do not presently maintain a Schwab account and wish to establish one,
simply complete a Schwab Account Application (available by calling 800-2
NO-LOAD, 24 hours a day, or by contacting your local Schwab office) and mail or
deliver it to your local Schwab office. You may also mail the application to
Schwab at 101 Montgomery Street, San Francisco, CA 94104. Corporations and other
organizations should contact their local Schwab office to determine which
additional forms may be necessary to open a Schwab account.
    
 
   
You may deposit funds into your Schwab account by check or wire. All deposit
checks should be made payable to Charles Schwab & Co., Inc. If you would like to
wire funds into your Schwab account, please contact your local Schwab office for
instructions.
    
 
   
You must have funds in your Schwab account in order to purchase Fund shares. If
funds (including those transmitted by wire) are received by Schwab before the
time of the Fund's last daily net asset calculation (normally 4:00 p.m. Eastern
time), they will be available for investment on that day. If funds arrive after
that time, they will be available for investment the next Business Day.
    
----------------------------------------------------
THE FUND MAY BE USED TO "SWEEP" FREE CREDIT BALANCES
IN YOUR SCHWAB BROKERAGE ACCOUNT.
----------------------------------------------------
 
METHODS OF PURCHASING SHARES. Automatic Investment: When opening a Schwab
brokerage account, an investor will be asked to select a SchwabFunds(R) class or
series with sweep privileges as a "primary fund." (If a selection is not made,
the Schwab Money Market Fund will automatically become the investor's primary
fund.) An initial purchase of shares of the primary fund selected will be made
automatically pursuant to the procedures described below when the free credit
balance in the investor's Schwab brokerage account (including deposits, proceeds
of sales of securities, and miscellaneous cash dividends and interest, but not
amounts held by Schwab as collateral for margin obligations to Schwab) exceeds
$1,000 on the last Business Day of the week. Thereafter, free credit balances in
the investor's Schwab brokerage account which, in total, equal or exceed $100 on
the last Business Day of any week will be automatically invested in the primary
fund on the first Business Day of the following week. If an investor's free
credit balance is less than $100, it will not be invested in the primary fund,
but will remain a credit to the investor's Schwab brokerage account. In certain
limited circumstances, free credit balances in certain accounts may be
automatically invested at different times. Upon request, a free credit balance
in a Schwab brokerage account totalling $20,000 or more may be invested in the
appropriate primary fund on the Business Day following receipt by the Transfer
Agent of investor instructions.
 
   
An investor with an existing Schwab brokerage account may add the automatic
investment feature to his or her account by completing the appropriate section
of the Schwab Account Application available at any Schwab office. A shareholder
may change primary funds by calling or writing his or her local Schwab office or
writing Schwab at the address listed on the cover of this Prospectus. Note that
the automatic reinvestment feature is not available for Value Advantage Shares
of any fund.
    
 
                                       17
<PAGE>   102
 
--------------------------------------------------
SHARES OF THE FUND MAY ALSO BE PURCHASED DIRECTLY.
--------------------------------------------------
 
   
DIRECT PURCHASE: A Schwab account holder may buy shares of the Fund (if it is
not his or her primary fund) by placing an order directly with a Schwab
registered representative. The minimum initial investment for such a "secondary
fund" purchase is $1,000, and subsequent investments must be at least $100. The
minimum initial investment for the Value Advantage Shares is $25,000 and the
minimum account balance for the Value Advantage Shares is $20,000.
    
---------------------------------------
TWO DISTRIBUTION OPTIONS ARE AVAILABLE.
---------------------------------------
 
   
DISTRIBUTION OPTIONS. The Schwab account standing instructions that you selected
in your Schwab Account Application will determine which of the two distribution
options listed below will apply to you. Fund distributions will be automatically
reinvested, unless the Transfer Agent has received instructions that
distributions be mailed to you as they are paid. Please contact your local
Schwab office if you already have a Schwab account and wish to change your
account standing instructions.
    
 
1. AUTOMATIC REINVESTMENT: All distributions will be reinvested in additional
   full Sweep Shares of the Fund at the net asset value next determined after
   their payable date.
 
2. RECEIVE DIVIDENDS BY MAIL: All distributions will be credited to your Schwab
   account as of the payable date. If your account is coded to have dividends
   mailed immediately, checks will normally be mailed the Business Day after
   distributions are credited.
 
   
For information on how to wire funds from your Schwab account to your bank, see
"Other Important Information--Wire Transfers to Your Bank."
    
 
   
OTHER PURCHASE INFORMATION. The minimum amounts required for automatic
investment/direct purchase may be reduced or waived on certain occasions. (See
"Purchase and Redemption of Shares" in the Statement of Additional Information.)
Free credit balances in accounts of certain categories of investors, such as
holders of Schwab custodial accounts, may be invested automatically irrespective
of amount. The Fund reserves the right, in its sole discretion and without prior
notice to shareholders, to withdraw or suspend all or any part of the offering
made by this Prospectus, to reject purchase orders or to change the minimum
investment requirements. All orders to purchase shares of the Fund are subject
to acceptance by the Fund and are not binding until confirmed or accepted.
Schwab will charge a $15 service fee against an investor's Schwab account should
his or her check be returned because of insufficient or uncollected funds or a
stop payment order.
    
 
HOW TO EXCHANGE SHARES
-------------------------------------------------
   
SHARES OF THE FUND MAY BE EXCHANGED FOR SHARES OF
OTHER FUNDS SPONSORED BY SCHWAB.
    
-------------------------------------------------
    
The exchange privilege allows you to exchange your SchwabFunds(R) shares for
shares of any other SchwabFunds class or series available to investors in your
state. Thus, you can conveniently modify your investments if your goals or
market conditions change. An exchange will involve the redemption
 
                                       18
<PAGE>   103


of shares and the purchase of shares in another fund. An exchange will be
treated as a sale of the shares for federal income tax purposes. Note that you
must meet the minimum initial or subsequent investment requirements applicable
to the shares you wish to receive in an exchange. The Fund reserves the right on
60 days' written notice to modify, limit or terminate the exchange privilege.
    
 
METHODS OF EXCHANGING SHARES.
 
BY PHONE:
 
   
  To exchange between any of the SchwabFunds(R) by telephone, please call your
  local Schwab office during regular business hours or 800-2 NO-LOAD, 24 hours a

HOW TO REDEEM SHARES
 
   
AUTOMATIC REDEMPTION. Redemptions will be automatically effected by the Transfer
Agent to satisfy debit balances in an investor's Schwab account or to provide
necessary cash collateral for an investor's margin obligation to Schwab.
Redemptions will also be automatically effected to settle securities
transactions with Schwab if an investor's free credit balance on the day before
settlement is insufficient to settle the transactions. Each Schwab account will,
as of the close of business each Business Day, be automatically reviewed for
debits and pending securities settlements, and, after application of any free
credit balances in the account to such debits, a sufficient number of shares of
the primary fund and, to the extent necessary, any other Schwab Money Fund(s) in
the account, will be redeemed the following Business Day to satisfy any
remaining debits.
    
 
                                       19
<PAGE>   104
 
   
DIRECT REDEMPTION. Shareholders may also place redemption orders directly by
contacting their local Schwab office by telephone, mail or in person, or by
mailing written instructions to Schwab (at the address listed on the Prospectus
cover page).
    
 
   
Normally a check for a shareholder's redemption proceeds will be available at
the investor's local Schwab office on the Business Day after Schwab's Mutual
Fund Transfer Agency Department receives proper redemption instructions. Checks
will normally be mailed to investors who specifically request such mailing on
the Business Day following share redemption. If you purchased shares by check,
your redemption proceeds may be held in your Schwab account until your check
clears (which may take up to 15 days). Depending on the type of Schwab account
you have, your money may earn interest during any holding period.
    
 
   
The Fund may suspend redemption rights or postpone payments at times when
trading on the Exchange is restricted, the Exchange is closed for any reason
other than its customary weekend or holiday closings, emergency circumstances as
determined by the SEC exist, or for such other circumstances as the SEC may
permit.
    
 
OTHER IMPORTANT INFORMATION
 
   
MINIMUM BALANCE AND BROKERAGE ACCOUNT REQUIREMENTS. Due to the relatively high
cost of maintaining smaller holdings, the Fund reserves the right to redeem a
shareholder's shares if, as a result of redemptions, their aggregate value drops
below the $100 minimum balance requirement for the Sweep Shares of the Fund. The
Fund will notify shareholders in writing 30 days before taking such action to
allow them to increase their holdings to at least the minimum level. Also note
that, because they can only be held in Schwab accounts, Fund shares will be
automatically redeemed should the Schwab account in which they are carried be
closed.
    
 
   
CONSOLIDATED MAILINGS. In an effort to reduce the Fund's mailing costs, the Fund
consolidates shareholder mailings by household. This consolidation means that a
household having multiple accounts with the identical address of record will
receive a single package during each shareholder mailing. If you do not wish
this consolidation to apply to your account(s), please write to SchwabFunds(R)
at 101 Montgomery Street, San Francisco, CA 94104 to that effect.
    
 
   
WIRE TRANSFERS TO YOUR BANK. If you so instruct your local Schwab office, funds
can be wired from your Schwab account to your bank account. Call your local
Schwab office for additional information. A $15 service fee will be charged
against your Schwab account for each wire sent.
    
 
   
SCHWAB ONE(R) ACCOUNT FEATURES. Shareholders who hold shares of the Fund in
Schwab One accounts are entitled to redeem Fund shares through debit cards and
checks. Investors should contact Schwab if they are interested in the benefits
and requirements of a Schwab One account.

KEY FEATURES OF THE FUND
 
MAXIMUM CURRENT INCOME AND SAFETY. Our goal is to provide you with the highest
possible current income while preserving your investment and providing you with
quick access to your money. To achieve this goal, the Fund invests in
high-quality, short-term debt securities. (See "Investment Objective and
Policies.")
 
PRESERVATION OF INVESTMENT. The Fund seeks to maintain a stable net asset value
(known as the Fund's "NAV") of $1.00 per share.
 
READY ACCESS TO YOUR CASH. You can conveniently sell your shares of the Fund at
any time. Generally, your redemption check will be available the next Business
Day at your local Schwab office, or it can be mailed directly to you.
 
LOW COST INVESTING. The Fund was designed with operating expenses well below the
industry average. (See "Matching the Fund to Your Investment Needs.")
Additionally, you pay no sales fee when you buy Fund shares. Fees may be charged
for balances and transactions under the required minimums.
 
   
PROFESSIONAL MANAGEMENT OF THE FUND. Charles Schwab Investment Management, Inc.
(referred to in this Prospectus as the "Investment Manager") currently manages
the mutual funds in the SchwabFunds FamilyTM, a family of 18 mutual funds with
over $28 billion in assets as of July 31, 1995. (See "Organization and
Management of the Fund--The Investment Manager.")
    
 
SHAREHOLDER SERVICES. Schwab's professional representatives are available
toll-free 24 hours a day at 800-2 NO-LOAD to service your account, or you can
call your local Schwab office during regular business hours. (See "Investing in
the Fund.")

your account activity that combines all of your mutual fund activity into one
report.
 
READING THIS PROSPECTUS. For your ease of reading, we have italicized certain
terms which have been included in the glossary at the end of this Prospectus. If
you are unsure of the meaning of any italicized term, check the glossary.
References to "you" and "your" in this Prospectus refer to prospective investors
and/or current shareholders, while references to "us," "our" and "our Fund"
refer to the Fund generally.
 
SUMMARY OF EXPENSES
 
ANNUAL OPERATING EXPENSES
 
Our Fund pays its own annual operating expenses from its income and assets.
These expenses include management fees paid to the Investment Manager, transfer
agency fees, and other expenses. These expenses cover, for example, services
such as investment research and management of the portfolio, and maintaining
shareholder records. Because these fees are paid from the Fund's income and
assets, they are factored into the price of the Fund's shares and into the
annual dividends paid to shareholders. As a shareholder, you are not charged any
of these fees directly.

<PAGE>   110
 
YOUR FEES FOR BUYING AND SELLING SHARES
 
   
You pay no sales fee when you buy the Fund's shares. Because the Fund is
designed for high balance accounts, the Transfer Agent charges a $5
administrative fee if you sell or exchange shares worth less than $5,000. The
Transfer Agent charges a $5 fee each month that your Fund account balance falls
below the required $20,000 minimum, or below $15,000 for Individual Retirement
Accounts and other retirement accounts. The Transfer Agent will notify you in
writing 15 days before this fee is assessed in order to give you time to bring
your account balance up to the minimum amount.
    
 
The following fees (except the administrative fee) are stated as a percentage of
how much the Fund was worth on an average day over the past year.
 
   
<TABLE>

SHAREHOLDER TRANSACTION EXPENSES:

     Management Fee (after fee reduction) 2.......................................    0.35%
     12b-1 Fees...................................................................     None
     Other Expenses (after fee reductions and/or expense reimbursements)..........    0.05%
TOTAL FUND OPERATING EXPENSES 3,4.................................................    0.40%
</TABLE>
    
 
1  If you sell or exchange shares in an amount less than $5,000, you will be
subject to a $5 administrative fee.
 
   
2  This amount reflects a reduction by the Investment Manager, which is
guaranteed through at least April 30, 1996. If there were no such reduction, the
maximum management fee would be 0.46% of the Fund's average daily net assets.
    
 
   
3  This amount reflects the guarantee by Schwab and the Investment Manager that,
through at least April 30, 1996, the total fund operating expenses of the Fund
will not exceed 0.40% of the Fund's average daily net assets. Without this
guarantee, which was in effect during the fiscal year ended December 31, 1994,
the Fund's total operating expenses would have been 0.79% of the Fund's average
daily net assets.
    
 
   
4  Schwab currently imposes no fees for opening and maintaining a Schwab
brokerage account. Effective October 1, 1995, Schwab will institute a $1,000
minimum equity requirement for brokerage accounts ($500 for custodial accounts).
A quarterly fee of $7.50 will be charged on accounts that fall below the
minimum. This fee, if applicable, will be charged at the end of each quarter and
will be waived if there has been one commissionable trade within the last six
months, or if the shareholder's combined account balances at Schwab total
$10,000 or more. Schwab imposes no fees for opening and maintaining a Schwab
One(R) account with a minimum balance of $5,000. Schwab One accounts with
balances below $5,000 are subject to a monthly fee of $5 if there have been
fewer than two commissionable trades within the last 12 months. Schwab
Individual Retirement Accounts with balances of $10,000 or more by September 15,
1995 are not charged Schwab's $29 annual IRA account fee for the life of the
account. Schwab Keogh plans are currently charged an annual fee of $45.

THE PRECEDING TABLE IS AN EXAMPLE ONLY, AND DOES NOT REPRESENT PAST OR FUTURE
EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THE EXPENSES SHOWN IN THE
EXAMPLE. This example reflects the guarantee by Schwab and the Investment
Manager that, through at least April 30, 1996, total operating expenses of the
Fund will not exceed 0.40% of the Fund's average daily net assets. Also, this
example does not include the $5 administrative fee on sales or exchanges of Fund
shares equal to or less than $5,000. Nor does this example include the $5
monthly fee charged on balances that fall below $20,000, or $15,000 for
Individual Retirement Accounts and other retirement accounts. Please remember,
that while this example assumes a 5% annual return on investment, the Fund's
actual return may be more or less than the 5% annual return used in this
example.
    
 
The purpose of the preceding table is to help you understand the various costs
and expenses you will bear directly or indirectly when you invest in the Fund.

The Investment Manager and Schwab reduced a portion of their fees and absorbed
certain expenses in order to limit the Fund's ratio of operating expenses to
average net assets. Had these fees and expenses not been reduced and absorbed,
the ratio of expenses to average net assets for the periods ended December 31,
1994, 1993 and 1992 would have been 0.79%, 0.82% and 0.94%*, respectively, and
the ratio of net investment income to average net assets would have been 4.01%,
2.54% and 2.62%*, respectively.

MATCHING THE FUND TO YOUR INVESTMENT NEEDS
 
Because the Fund is designed for larger balance accounts, we can keep the
operating expenses lower than the industry average, which helps provide more
competitive yields. The table below shows the Fund's total operating expenses
compared to the industry average for similar type funds.
 
<TABLE>

</TABLE>
 
Note:  These amounts represent total operating expenses after fee waivers for
       first tier money funds, not including institutional money funds.
 
Our Fund invests in high-quality money market securities and is designed for
high current yields. Because shares of our Fund are held in your Schwab account,
the proceeds from redemptions you make are available for other investment
purchases you make in your account. Keep in mind, however, that because the Fund
is intended for larger balance accounts, you may be charged a fee for
redemptions or exchanges under the required minimum or if your balance falls
below the required minimum.

Schwab also offers a selection of "sweep" money funds with lower minimums which
automatically invest the uninvested cash balances in your Schwab account in a
Schwab money fund which you select. A "sweep" money fund may be more suitable
for providing income on fluctuating cash balances in your account in between
other investments.
 
The Fund may be appropriate for a variety of investment programs which can be
long-term or short-term in nature. The Fund should not be a substitute for
building an investment portfolio tailored to your individual investment needs
and risk tolerance.
 
INVESTMENT OBJECTIVE AND POLICIES
 
Our Fund's investment objective is to provide maximum current income consistent
with liquidity and stability of capital. Because any investment involves risk,
we cannot guarantee achieving this objective. This investment objective is
fundamental.
 
To achieve this objective, we normally will invest in the following types of
U.S. dollar-denominated debt instruments, which our Investment Manager has
determined present minimal credit risk:
 
1. Bank certificates of deposit, time deposits or bankers' acceptances of
   domestic banks (including their foreign branches), U.S. branches of foreign
   banks, and foreign branches of foreign banks having capital, surplus and
   undivided profits in excess of $100 million.
 
2. Commercial paper rated in one of the two highest rating categories by
   Moody's, S&P, Duff, Fitch, or any other nationally recognized statistical
   rating organization (referred to in this Prospectus as an "NRSRO ") and
   commercial paper or notes of issuers who have an outstanding unsecured debt
   issue that is currently rated in one of the two highest rating categories by
   any NRSRO. The obligation must also be on the same or a higher level of
   priority as the rated issue, and it must be collateralized to the same extent
   as the rated issue. We may also invest in other corporate obligations such as
   publicly traded bonds, debentures and notes rated in one of the two highest
   rating categories by any NRSRO, as well as other similar securities which, if
   unrated by any NRSRO, the Investment Manager, using guidelines approved by
   the Board of Trustees, determines to be at least equal in quality to one or
   more of the securities mentioned above. (For a description of the ratings,
   see "Appendix--Ratings of Investment Securities" in the Statement of
   Additional Information.)
 
3. Obligations of, or obligations guaranteed by, the United States government,
   the Canadian government or their agencies or instrumentalities.
 
4. Repurchase agreements involving obligations that are suitable for investment
   under the categories listed above.
 
PRIVATE PLACEMENT SECURITIES. We may invest in commercial paper that is exempt
from registration according to Section 4(2) of the Securities Act of 1933, and
that is resold to qualified institutional buyers under Securities Act Rule 144A
(known as "Section 4(2) paper").
 
Federal securities laws restrict the disposition of Section 4(2) paper. Such
commercial paper is generally sold to institutional investors who agree that
they are purchasing the paper for investment and not for public distribution.
Section 4(2) paper normally is resold to other institutional investors through
or with the assistance of the issuer or investment dealers who make a market in
the Section 4(2) paper, thus providing liquidity.
 
                                        6
<PAGE>   114
 
Because it is not possible to predict with assurance exactly how the market for
Section 4(2) paper will develop, our Investment Manager, pursuant to guidelines
approved by the Board of Trustees, will carefully monitor the Fund's investments
in these securities, focusing on such important factors, among others, as
valuation, liquidity and availability of information. Our Fund's liquidity could
be reduced if qualified institutional buyers become temporarily uninterested in
purchasing these restricted securities.
 
We will not invest more than 10% of our assets in Section 4(2) paper (and other
illiquid securities) unless our Investment Manager determines, by continuously
referring to the appropriate trading markets and following the guidelines
approved by the Board of Trustees, that any Section 4(2) paper we hold in excess
of this level is at all times liquid.
 
ASSET-BACKED COMMERCIAL PAPER. We may invest in asset-backed commercial paper.
Repayment of this type of commercial paper is intended to be obtained from an
identified pool of assets, including automobile receivables, credit card
receivables, and other types of receivables. Asset-backed commercial paper is
issued by a special purpose vehicle (usually a corporation) that has been
established for the purpose of issuing the commercial paper and purchasing the
underlying pool of assets. The issuer of the commercial paper bears the direct
risk of prepayment on the receivables constituting the underlying pool of
assets. Credit support for such asset-backed commercial paper may be based on
the underlying assets or it may be provided by a third party. Credit enhancement
techniques include letters of credit, insurance bonds, limited guarantees (which
are generally provided by the seller), and over-collateralization. We apply the
same quality requirements to asset-backed commercial paper as we apply to other
securities we purchase.
 
EURODOLLAR CERTIFICATES OF DEPOSIT AND FOREIGN SECURITIES. We may purchase
Eurodollar certificates of deposit. However, when purchasing such certificates
we will consider their marketability, any possible restrictions on international
currency transactions and any regulations imposed on such securities by the
domicile country of the issuer. The regulatory requirements that apply to
certificates of deposit issued by U.S. banks may not apply to Eurodollar
certificates. Income from such certificates may be subject to foreign taxes.
 
We may invest in securities of foreign issuers, or securities principally traded
overseas. Such securities may involve special risks because of foreign economic,
political and legal developments, including changes in currency exchange rates,
regulations controlling the exchange of currency (including blocking any
exchange of currency), expropriation of assets or nationalization, imposition of
withholding taxes on dividend interest payments, and possible difficulty in
obtaining and enforcing judgments against foreign entities. Furthermore, issuers
of foreign securities are subject to different, often less comprehensive,
accounting, reporting and disclosure requirements than domestic issuers. The
securities of some foreign companies and foreign securities markets are less
liquid and at times more volatile than securities of comparable U.S. companies
and U.S. securities markets. Foreign brokerage commissions and other fees are
also generally higher than those imposed in the United States. There are also
special tax considerations that apply to securities of foreign issuers and
securities principally traded overseas.
 
                                        7
<PAGE>   115
 
VARIABLE RATE SECURITIES. We may invest in instruments which have interest rates
that are adjusted periodically, or which "float" continuously according to
formulas intended to minimize any fluctuation in the values of the instruments
("Variable Rate Securities"). The interest rate of Variable Rate Securities is
ordinarily determined by reference to, or is a percentage of, an objective
standard such as a bank's prime rate, the 90-day U.S. Treasury bill rate, or the
rate of return on commercial paper or bank certificates of deposit.
 
Generally, changes in the interest rate on Variable Rate Securities reduce the
fluctuation of their market value. Accordingly, as interest rates decrease (or
increase), Variable Rate Securities experience less capital appreciation (or
depreciation) than fixed-rate obligations.
 
Some Variable Rate Securities ("Variable Rate Demand Securities") allow the
purchaser to resell the securities at an amount approximately equal to amortized
cost, or to the principal amount plus accrued interest. Like other Variable Rate
Securities, the interest rate on Variable Rate Demand Securities varies
according to some objective standard that is intended to minimize fluctuations
in the values of the securities. We determine the maturity of Variable Rate
Securities in accordance with SEC rules.
 
ILLIQUID SECURITIES. We may purchase illiquid securities, including repurchase
agreements maturing in more than seven days, provided that no more than 10% of
our net assets valued at the time of the transaction are invested in such
securities.
 
GOVERNMENT SECURITIES. We may invest in government securities, including U.S.
Treasury notes, bills, and bonds, which are backed by the full faith and credit
of the U.S. Government. Some securities issued by U.S. Government agencies or
instrumentalities are supported by the credit of the agency or instrumentality,
for example, those issued by the Federal Home Loan Bank, while others, such as
those issued by the Federal National Mortgage Association, Farm Credit System,
and Student Loan Marketing Association have an additional line of credit with
the U.S. Treasury. However, there is no guarantee that the U.S. Government will
provide support to such agencies or instrumentalities. Accordingly, such
securities may involve risk of loss of principal and interest.
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. We may purchase securities on a
"when-issued" or "delayed delivery" basis. When-issued or delayed delivery
securities are securities purchased for future delivery at a stated price and
yield. Generally, we will not pay for such securities or start earning interest
on them until we receive them. Securities purchased on a when-issued or delayed
delivery basis are recorded as an asset. The value of such securities may change
as the general level of interest rates changes.
 
We will not invest more than 25% of our assets in when-issued or delayed
delivery securities. We will not purchase such securities for speculative
purposes, and will expect to actually acquire the securities when we purchase
them. However, we reserve the right to sell any such securities before their
settlement dates, if our Investment Manager deems such a sale advisable.
 
REPURCHASE AGREEMENTS. We may invest in repurchase agreements, which are
instruments under which we acquire ownership of a security from a broker-dealer
or bank who then agrees to repurchase the security at a mutually agreed upon
time and price. The repurchase price, which is
 
                                        8
<PAGE>   116
 
higher than the purchase price, determines the security's yield during the time
we hold it. Securities underlying repurchase agreements may have maturities
longer than one year.
 
If the seller of a repurchase agreement becomes bankrupt or otherwise defaults,
we might incur expenses in enforcing our rights and could experience losses,
including a decline in the value of the underlying securities and a loss of
income. We will enter into repurchase agreements only with banks and other
recognized financial institutions that our Investment Manager deems
creditworthy.
 
INVESTMENT TECHNIQUES USED BY THE FUND
 
MATURITY. We will purchase only securities that mature in 397 days or less, or
securities which have a variable rate of interest that is readjusted no less
frequently than every 397 days.
 
BORROWING POLICY. We may not borrow money except for temporary purposes to meet
redemption requests that could not otherwise be met without immediately selling
portfolio securities. We may borrow an amount up to one-third of the value of
our total assets and may pledge up to 10% of our net assets to secure such
borrowings. We will not borrow for leverage purposes. This borrowing policy is
fundamental.
 
LIMITATIONS ON INVESTMENTS. We are subject to the following limitations, which
apply to all our investments other than securities issued or guaranteed by the
U.S. Government, its agencies, and instrumentalities:
 
1. DIVERSIFICATION. Except as provided in this paragraph, we may not invest more
than 5% of the value of our total assets in the securities of one issuer.
However, we may invest more than 5% of our total assets in the First Tier
securities of a single issuer for a period of up to three Business Days after
the purchase thereof, provided further that we may not make more than one
investment in accordance with the foregoing proviso at any time. For purposes of
this limitation, a security is considered to be issued by the governmental
entity (or entities) whose assets and revenues back the security. In certain
circumstances, the guarantor of a security may also be considered to be an
issuer in connection with such a guarantee.
 
2. CONCENTRATION. As matter of fundamental policy, we will not invest 25% or
more of the value of our total assets in the securities of issuers conducting
their principal business activities in the same industry.
 
ORGANIZATION AND MANAGEMENT OF THE FUND
 
MANAGEMENT FUNCTIONS AND RESPONSIBILITIES
 
GENERAL OVERSIGHT. Our Board of Trustees and officers meet regularly to review
our investments, performance, expenses and other business affairs.
 
   
THE INVESTMENT MANAGER. Our Investment Manager, Charles Schwab Investment
Management, Inc., manages our Fund, subject to the authority of the trustees and
officers of the Trust. Our Investment Manager, founded in 1989, is a wholly
owned subsidiary of The Charles Schwab Corporation and is the investment adviser
and administrator of the SchwabFunds(R) mutual funds, a group of registered
 
                                        9
<PAGE>   117
 

open-end management investment companies. As of July 31, 1995, the SchwabFunds
had aggregate net assets in excess of $28 billion.
    
 
Through a professional staff of portfolio managers and securities analysts, our
Investment Manager provides us with a continuous investment program, including
general investment and economic advice regarding our investment strategies,
manages our investment portfolio, performs expense management, accounting, and
record keeping, and provides other services necessary to our operation.
 
TRANSFER AGENT AND SHAREHOLDER SERVICES. Schwab serves as our Shareholder
Services Agent and Transfer Agent. Schwab provides information to our
shareholders, reports share ownership and all account activities, and responds
to all inquiries from shareholders. Schwab also distributes informational
literature, and furnishes the office space and equipment, telephone facilities,
and personnel that is necessary in providing shareholders services.
 
   
Schwab was established in 1971 and is one of America's largest discount brokers.
Schwab provides low-cost securities brokerage and related financial services to
over 2.5 million active customer accounts and has over 200 branch offices.
Schwab also offers convenient access to financial information services and
provides products and services that help investors make investment decisions.
Schwab is a wholly owned subsidiary of The Charles Schwab Corporation. Charles
R. Schwab is the founder, Chairman and Chief Executive Officer, and a Director
of The Charles Schwab Corporation and, as of July 31, 1995, was the beneficial
owner of approximately 20.5% of the outstanding shares of that corporation. Mr.
Schwab may be deemed to be a controlling person of Schwab and our Investment
Manager.
    
 
ACCOUNTANTS. Price Waterhouse LLP is our certified independent public
accountant. Their address is 555 California Street, San Francisco, California
94104.
 
OPERATING FEES AND EXPENSES
 
For investment management services, under the terms of its Investment Advisory
and Administration Agreement with the Trust, our Fund pays a graduated annual
fee to the Investment Manager. This fee is based on the value of our Fund's
average daily net assets and is payable monthly by the Fund in the amount of
0.46% of the first $2 billion of the Fund's average daily net assets; 0.45% of
such assets over $2 billion but less than $3 billion; and 0.40% of such assets
over $3 billion.
 
   
Our Investment Manager guarantees that, through at least April 30, 1996, the
Fund's management fee will not exceed 0.35% of its average daily net assets, and
our Investment Manager and Schwab guarantee that the Fund's total fund operating
expenses will not exceed 0.40% of the Fund's average daily net assets. The
effect of this voluntary expense limitation is to maintain or increase the
Fund's total return to shareholders. For the fiscal year ended December 31,
1994, the Fund paid an investment management fee of 0.11% and total expenses of
0.40% of the Fund's average daily net assets.
    
 
                                       10
<PAGE>   118
 
For its services as Transfer Agent, Schwab receives an annual fee of 0.05% of
the Fund's average daily net assets. In addition, for shareholder services
provided, Schwab receives an annual fee of 0.20% of the Fund's average daily net
assets.
 
Schwab serves as our Fund's distributor but receives no compensation for this
service. PNC Bank, N.A. is our Fund's custodian.
 
OTHER EXPENSES. The Trust pays the expenses of our Fund's operations, including
the fees and expenses for independent auditors, legal counsel, custodians, the
cost of maintaining books and records of account, taxes, registration fees, and
the fees and expenses of qualifying the Trust and its shares for distribution
under federal and state securities laws, and industry association membership
dues.
 
The Trust generally allocates these expenses among the individual investment
portfolios ("Series"). This allocation is based on the relative net assets of
the Series at the time the expenses are incurred. However, expenses directly
attributable to a Series are charged to that Series.
 
OTHER INFORMATION
 
   
The Trust was organized as a business trust under the laws of Massachusetts on
October 20, 1989 and may issue an unlimited number of shares of beneficial
interest or classes of shares in one or more Series. Currently the Trust offers
shares of nine Series, which may be organized into one or more classes of shares
of beneficial interest. The Board of Trustees may authorize the issuance of
shares of additional Series or classes, if it deems it to be desirable to do so.
Shares of each Series or class have equal, noncumulative voting rights and equal
rights as to dividends, assets and liquidation of such Series except to the
extent such voting rights or rights as to dividends, assets and liquidation vary
among classes of a Series.
    
 
ANNUAL SHAREHOLDER MEETINGS. The Trust is not required to hold annual meetings
and does not intend to do so except in connection with certain matters, such as
a change in our fundamental policies, election of Trustees or approval of a new
investment advisory agreement. In addition, a Trustee may be elected or removed
by shareholders at a special meeting called upon written request of shareholders
owning in the aggregate at least 10% of the outstanding shares of the Trust.
 
YOUR VOTING RIGHTS. If we were to make changes to our management or fundamental
policies, you would be asked to vote as a shareholder because shareholders have
voting rights on these matters. If a meeting is held and you cannot attend, you
may vote by proxy. Before the meeting, we will send you proxy materials that
explain the issues to be decided and include a voting card for you to mail back.
You are entitled to one vote for each share owned. Unless permitted by the 1940
Act, shareholders vote by Series and not in the aggregate. For example, when
voting to approve an investment advisory agreement for a Series, only
shareholders of that Series may vote; when voting to elect Trustees,
shareholders of all the Series vote in the aggregate.

INVESTING IN THE FUND
 
HOW TO BUY SHARES
 
OPENING A SCHWAB ACCOUNT. You may buy our shares only through a Schwab account.
You can open a Schwab account by completing the appropriate account application.
(Corporations and other organizations should contact a Schwab office to find out
the additional forms that must be completed to open an account.)
 
Within your Schwab account, you have access to other investments available at
Schwab such as stocks, bonds and other mutual funds. Additionally, the
Securities Investor Protection Corporation (known as "SIPC") will provide
account protection up to $500,000 for your securities, including shares in the
Fund, which you hold in a Schwab brokerage account. However, SIPC account
protection does not protect you from any loss of principal due to market or
economic conditions.
 
SCHWAB ACCOUNT MINIMUMS AND ASSOCIATED FEES. Schwab reserves the right to
require a $1,000 initial deposit and account balance minimum to maintain a
Schwab standard brokerage account. Schwab may charge a fee if your balance is
under this minimum or if trading requirements are not met.
 
   
Certain fees may be charged to Schwab accounts which do not maintain required
minimum balances. (See "Summary of Expenses--Your Fees for Buying and Selling
Shares" for more information.) Note that, in addition to these account minimums,
there are higher minimum investment and other requirements applicable to the
Fund, which are described below.
    
 
DEPOSITING FUNDS AND MEETING THE FUND'S INVESTMENT MINIMUMS. Once you have
opened your account or if you already have a Schwab account, you can deposit
funds by check or wire. Your check should be made payable to Charles Schwab &
Co., Inc. Contact your Schwab representative for instructions on how to deposit
funds by wire.
 
   
The minimum initial investment in the Fund is $25,000, or $15,000 for an
Individual Retirement Account or other retirement plan. After you have bought
the minimum amount of shares for your initial investment, you can buy additional
shares in amounts of at least $5,000, or $2,000 for an IRA or other retirement
plan. The Transfer Agent imposes a $5 fee for each month your Fund account
balance falls below the required $20,000 minimum or $15,000 for an IRA or other
retirement plan. The Transfer Agent reserves the right to waive these minimums
from time to time for clients of Schwab Institutional, a division of Schwab, and
for certain other investors. See the Statement of Additional Information for
more details.
    
 
We, in our sole discretion and without prior notice to you, reserve the right to
reject orders to buy shares, to change the minimum investment requirements, and
to withdraw or suspend any part of the offering made by this Prospectus. In
particular, if you engage in excessive exchange or redemption activity, we
reserve the right to refuse your future orders to buy shares in order to
minimize the costs to the Fund associated with these practices. All orders to
buy shares must be accepted by us, and orders are not binding until we confirm
or accept them in writing. Schwab will charge your Schwab brokerage account a
$15 service fee for any check returned because of insufficient or uncollected
funds, or because of a stop payment order.
 
                                       12
<PAGE>   120
 
WHEN YOU CAN BUY SHARES. You must have funds in your Schwab account in order to
buy our shares. Funds received by Schwab before 4:00 p.m. (Eastern time) can be
used to buy our shares on that day. Funds that arrive after that time can be
used to buy shares the next Business Day. Schwab's Mutual Fund Transfer Agency
Department will execute an order to buy shares upon receipt of the order.
 
DISTRIBUTION OPTIONS. When you first buy our shares, you may choose one of the
two following distribution options:
 
1. AUTOMATIC REINVESTMENT: All distributions will be reinvested in additional
   full and fractional shares of the Fund at the net asset value next determined
   on their payable date; or
 
2. RECEIVE YOUR DIVIDENDS IN CASH: All distributions will be credited to your
   Schwab account on the date distributions are payable. If you choose to have
   your dividends mailed, a check will be mailed to you the Business Day after
   distributions are credited to your account.
 
To change the distribution option you have selected, call your local Schwab
office or 800-2 NO-LOAD.
 
You can request that your Schwab office wire funds from your Schwab account to
your bank account. There is a $15 fee for each wire transfer of funds.
 
   
HOW TO EXCHANGE SHARES
    
 
   
You can exchange your investment in our shares for shares of other
SchwabFunds(R) subject to the following terms and conditions:
    
 
   
        - The shares you seek to buy must be available in your state and your
          purchase must meet that fund's eligibility requirements.
    
        - After the Transfer Agent receives your exchange request, the Transfer
          Agent will sell your shares at the net asset value next determined (on
          the same day as the Transfer Agent received your request, if it was
          received by 4:00 p.m. (Eastern time) and on the next Business Day if
          your request was received after that time).
        - The Transfer Agent will buy shares in the fund you have selected at
          the net asset value of that fund's shares next determined after the
          sale of the Fund shares you are exchanging (on the same day as the
          Transfer Agent received your request, if it was received by 4:00 p.m.
          (Eastern time) and on the next Business Day if your request was
          received after that time).
        - The Transfer Agent will charge you a $5 administrative fee if you are
          exchanging less than $5,000 of our shares.
   
        - You must meet the initial or subsequent minimum investment
          requirements of the fund whose shares you are buying in the exchange.
    
 
   
We reserve the right to modify, limit, or terminate the exchange privilege upon
60 days' written notice. For federal income tax purposes, an exchange is treated
as a sale of shares.
    
 
EXCHANGING SHARES BY TELEPHONE. You can exchange shares by telephone by calling
your local Schwab office during regular business hours, or by calling 800-2
NO-LOAD. The right to initiate transactions by telephone is automatically
available through your Schwab account.

We will follow reasonable procedures to confirm that your telephone instructions
are genuine. If we follow telephone orders that we reasonably believe to be
genuine, we will not be liable for any losses you may experience. If we do not
follow reasonable procedures to confirm that your telephone order is genuine, we

        - the number of our shares you want to exchange.
 
You should remember that it may be difficult to reach us by telephone to
exchange shares during periods of drastic economic or market changes, when our
phone lines become very busy with calls from other investors. If you want to
exchange your shares but have trouble reaching us by telephone, you may want to
use one of the other ways we offer for exchanging your shares, even though these
procedures may mean the exchange of your shares may take longer.
 
EXCHANGING SHARES BY MAIL. You can also exchange shares by writing to your local
Schwab office or to the address on the cover of this Prospectus.
 
We need the following information in a letter from you in order to process your

subject to the following terms and conditions:
 
        - the selling price of your shares will be the net asset value per share
          next determined after the Transfer Agent has received proper
          instructions from you;
        - the Transfer Agent may sell additional shares from your account to pay
          the administrative fee;

          to sell your shares;
        - a check will be mailed to you on the Business Day following the sale
          of your shares if you specifically request that it be mailed; and

          is restricted, the Exchange is closed for any reason other than its
          normal weekend or holiday closings, emergency circumstances as

          permit.
 
The Transfer Agent will charge you a $5 administrative fee if you sell shares
equal to or less than $5,000. The Transfer Agent will waive this minimum for
certain clients of Schwab Institutional, a division of Schwab, and for certain
other investors. See the Statement or Additional Information for more details.

IMPORTANT INFORMATION ABOUT YOUR INVESTMENT
 
DIVIDENDS AND OTHER DISTRIBUTIONS
 
   
Each Business Day we determine our net investment income, which we compute by
subtracting our expenses for that day from the amount we earned on our
investments on that day. We declare dividends from this net investment income
each Business Day for those who were shareholders of record at the previous net
asset value calculation. We pay, or reinvest, dividends on the 15th day of each
month if it is a Business Day. If the 15th is not a Business Day, we pay
dividends on the next Business Day.
    
 
INCOME TAX INFORMATION
 
The following is only a very brief summary of some of the federal income tax
consequences that affect us and our shareholders. Therefore, it is important
that you consult with advisers about your own tax situation.
 
   
We have qualified as a regulated investment company under the Code. In order to
continue to qualify, we will distribute to our shareholders on a current basis
substantially all of our investment company taxable income, and we will meet
certain other requirements. As a regulated investment company, we will pay no
federal income taxes to the extent that we distribute our earnings to our
shareholders.
    
 
We will provide you with a record of all dividends, distributions, purchases,
and sales on your regular Schwab brokerage account statement. At least once a
year we will notify you of the federal income tax consequences of all
distributions made that year to your account.
 
All distributions we make, except for long-term capital gains distributions (if
any), are taxable to shareholders as ordinary income. Reinvested distributions
will be taxable as if they had been received by shareholders in cash. It is not
expected that any portion of the dividends we pay will qualify for the corporate
dividends received deduction.
 
HOW WE DETERMINE THE PRICE OF YOUR SHARES
 
The price of a share is its net asset value, which we determine each Business
Day at the close of trading on the Exchange, generally at 4:00 p.m., Eastern
time. We determine the price of a share by adding our total assets, subtracting
any liabilities, and then dividing the resulting number by the number of shares
outstanding. While we try to maintain our net asset value at a constant $1 per
share, we cannot guarantee this value.
 
We do not price the securities in our portfolio at market value. Instead, we
value our portfolio securities at the price we paid when we bought them,
adjusting this price to reflect amortization of premium or any discount. After
using this amortized cost method to determine the value of our investments, we
then compare this value with the market value of our investments.
 
We calculate the market value of our investments using one of the following
three methods: (1) we may use actual quotations provided by third-party pricing
services or market makers; (2) we may estimate the market value of the
instruments; or (3) we may use a value obtained from the yield data (published
by reputable sources) of money market instruments that are comparable to the
securities

we are valuing, using the mean between the bid and asked prices for the
instruments as the value of the instruments.
 
If a deviation of 1/2 of 1% or more between our net asset value per share as
calculated by market values and our $1 per share amortized cost value, or if
there is any other deviation which the Board of Trustees believes would result
in a material dilution to shareholders or purchasers, the Board of Trustees will
promptly consider what action, if any, should be taken.
 
HOW THE FUND REPORTS PERFORMANCE
 
From time to time, we may advertise our yield and effective yield. Our actual
performance will, of course, vary from year to year, and past performance in no
way represents or guarantees future performance. How we perform in any given
year will depend on the type and quality of securities in which we invest, the
market, and our operating expenses.
 
YIELD.  When we calculate our yield, we make some hypothetical assumptions about
how we will do for one year. Using the income generated over one 7-day period by
a hypothetical investment, we assume that this amount of income is generated
each week for one year. This income for the year is then shown as a percentage
of our hypothetical investment. (See the section entitled "Yield" in the
Statement of Additional Information for more information.)
 
EFFECTIVE YIELD. We calculate effective yield the same way, but we assume that
the income generated by our hypothetical investment is compounded weekly over
our hypothetical year. Because of the effect of compounding, the effective yield
will be slightly higher than the yield.
 
   
COMPARING THE FUND'S PERFORMANCE WITH OTHER FUNDS. We may compare the
performance of our Fund with the performance of other mutual funds by comparing
the ratings of mutual fund rating services, various indices of investment
performance, United States Government obligations, bank certificates of deposit,
the consumer price index, and other investments for which reliable data is
available.
    
 
ANNUAL REPORT AND SEMI-ANNUAL REPORT MAILINGS. Twice a year, we will provide a
report to all shareholders describing our performance and outlining the
investments held in the portfolio. In order to reduce mailing costs, we
consolidate these shareholder mailings by household. If a household has multiple
accounts and the same address of record for all the accounts, we will send
mailings for all accounts at that address in a single package. If you do not
want this consolidation of mailings to apply to your account, please write to
SchwabFunds(R) at the address on the front of this Prospectus. To request a free
copy of our Annual Report (or Semi-Annual Report) to Shareholders, call your
local Schwab office or call 800-2 NO-LOAD.

GLOSSARY OF IMPORTANT TERMS
 
AMORTIZED COST METHOD: the method of calculating a money market mutual fund's
net asset value whereby portfolio securities are valued at the fund's
acquisition cost, as adjusted for amortization or premium or accretion of
discount, rather than at their value based on current market factors.
 
ANNUALIZED: calculated to represent a year; a statement produced by calculating
financial results covering less than a year to show what might happen when the
results are hypothetically extended to cover an entire year.
 
BUSINESS DAY: any day both the Federal Reserve Bank of New York and the New York
Stock Exchange are open for business. A Business Day normally begins at 9 a.m.
(Eastern time) when the Exchange opens, and usually ends at 4 p.m. (Eastern
time) when the Exchange closes.
 
CAPITAL GAIN OR LOSS: the increase or decrease in the value of a security over
the original purchase price. A gain is realized when the security that has
increased in value is sold. An unrealized gain or loss occurs when the value of
a security increases or decreases but the security is not sold. If a security is
held for more than 12 months and then sold at a profit, that profit is a
realized long-term capital gain. If it is sold at a profit after being held for
less than 12 months, that profit is a realized short-term capital gain.
 
CODE: The Internal Revenue Code of 1986, as amended.
 
COMMERCIAL PAPER: unsecured debt obligations issued by businesses and sold at a
discount but redeemed at par within 2 to 270 days.

MUTUAL FUND: See definition of "Open-End Fund" below.
 
NET ASSET VALUE (NAV): on a per share basis, the value of one share in the Fund.
This value is determined by adding the total Fund assets, subtracting all
liabilities, and then dividing the resulting number by the number of shares
outstanding.
 
1940 ACT: the Investment Company Act of 1940, as amended.
 
NONCUMULATIVE VOTING RIGHTS: the right of a shareholder to vote only the number
of shares owned at the time of voting.

S&P, Duff or Fitch.
 
OPEN-END FUND: also called a mutual fund; an investment company in which people
invest by buying its shares, thereby pooling their money and allowing the fund
to invest in a number of securities. The fund distributes the profits from these
investments, after expenses, to the fund's shareholders. Although shares in the
fund are sold publicly, they are not traded on an open exchange because the fund
will buy and sell shares to meet investor demand. Since the company is not
limited as to the number of shares it can issue, the company's capitalization is
not fixed but open.
 
PORTFOLIO: the total stocks, bonds, and other securities held by an individual
investor, a mutual fund, or a financial institution.
 
PRINCIPAL: capital; the original value of an investment or a debt; the face
value of a bond.
 
RISK: the possibility of losing all or part of an investment, that the value of
the investment will decrease, or that the investor will receive little or no
return on the investment.
 
S&P: Standard & Poor's Corporation, an NRSRO.
 
SCHWAB: Charles Schwab & Co., Inc. 101 Montgomery Street, San Francisco, CA
94104.
 
SECURITIES AND EXCHANGE COMMISSION (SEC): established by Congress to administer
the Securities Act of 1933 and other securities-related laws.
 
SECURITIES INVESTOR PROTECTION CORPORATION (SIPC): a government sponsored
private corporation that insures securities accounts held in brokerages for up
to $500,000 in the event of the bankruptcy or financial failure of the

TRANSFER AGENT: Charles Schwab & Co., Inc., 101 Montgomery Street, San
Francisco, CA 94104.
 
TRUST: The Charles Schwab Family of Funds.
 
YIELD: the dividend or interest paid by a security. The yield is calculated as a
percentage of the security's current market price. A stock selling for $80 per
share and paying dividends of $6.40 is yielding 8 percent ($6.40 / $80 = .08).
Likewise, a bond with a par or face value of $1,000 and a 9 percent interest
rate selling for $600 is yielding 15 percent ($90 / $600 = .15). Interest on a
bond is always based on the par or face value of the bond, while the yield or
return is based on the market price.
