KEY FEATURES OF THE FUND
 
PERFORMANCE. The investment objective of the Fund is to match the price and
dividend performance (total return) of the Schwab 1000 Index(R), an index
created by Schwab to represent the performance of the public market for common
stocks of United States companies. (See "The Schwab 1000 Index.") The Fund,
which is a diversified investment portfolio of the Trust, an open-end management
investment company, invests primarily in the securities of companies represented
in the Index. (See "Investment Objective and Policies.")
 
REDUCED RISK THROUGH DIVERSIFICATION. The Fund seeks to invest in the common
stocks of substantially all of the 1,000 companies that make up the Index. This
level of diversification reduces the risk associated with investments in
individual equity securities (typically, a decline in the value of individual
securities) because the Fund's investments will be spread over a wide range of
industries and common stock issues as opposed to being concentrated in a few
individual securities. (See "Investment Objective and Policies.")
 
LOW-COST INVESTING. The Fund brings a low-cost approach to investing with:
 
         - no sales charges;
         - an index fund management strategy designed to minimize overall
           operating expenses; and
         - the guarantee of Charles Schwab Investment Management, Inc. (the
           "Investment Manager") and Schwab that the Fund's total fund operating
           expenses will, at least through April 30, 1996, not exceed 0.49% of
           the Fund's average daily net assets. (By way of comparison, according
           to Morningstar, Inc., as of October 31, 1995 the total fund operating
           expenses of the average U.S. growth and income fund was 1.24% of its
           average daily net assets.) (See "Management of the Fund.")
 
MINIMIZATION OF CURRENT CAPITAL GAINS TAX LIABILITY. The Fund's investment
policies are designed to minimize current capital gains tax liability. (See
"Distributions and Taxes.")
 
PROFESSIONAL MANAGEMENT. The Investment Manager currently provides investment
management services to the mutual funds in the SchwabFunds Family(R), a family
of 21 mutual funds with approximately $31 billion in assets as of December 15,
1995. (See "Management of the Fund.")
 
SHAREHOLDER SERVICE. Schwab serves as the Fund's principal
underwriter/distributor, transfer agent, and shareholder service provider.
Schwab's professional representatives are available 24 hours a day to receive
your purchase, redemption, and exchange orders. Call your local Schwab office
during business hours or 800-2 NO-LOAD. TDD users may contact Schwab at
800-345-2550, 24 hours a day. As a discount broker, Schwab gives you investment

</TABLE>
 
1 Applies only to the redemption (including by exchange) of shares purchased and
held less than six months. The fee is paid to the Fund and is designed to
protect long-term investors from the cost of frequent investments and
redemptions by short-term investors. (See "How to Sell or Exchange Shares.") The
Fund reserves the right to waive this fee for certain clients of Schwab
Institutional and The Charles Schwab Trust Company and for certain
tax-advantaged retirement plans. Call your Schwab representative for more
information.
 
2 This amount has been restated to reflect a reduction by the Investment
Manager, which is guaranteed through at least April 30, 1996. If there were no
reduction, the maximum management fee would be 0.28% of the Fund's average daily
net assets.
 
3 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 for the Fund will not exceed 0.49% of the Fund's average
daily net assets. Without this guarantee which was in effect for the fiscal year
ended August 31, 1995, other expenses and total fund operating expenses would
have been 0.35% and 0.63%, respectively, of the Fund's average daily net assets.

4 You may be charged a fee if applicable minimum balances are not maintained in
your Schwab brokerage account or Schwab One(R) account. (See "How to Purchase
Shares -- Schwab Account Minimums and Associated Fees.") Schwab Individual
Retirement Accounts with balances of $10,000 or more by September 15, 1996 will
not be 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 "Tax-
Advantaged Retirement Plans.")
 
EXAMPLE. You would pay the following expenses on a $1,000 investment, assuming
(1) a 5% annual return and (2) redemption at the end of each time period:

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

Notes:
 
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
August 31, 1995, 1994, 1993, December 31, 1992 and 1991 would have been .63%,
 .56%, .49%*, .52% and 1.05%*, respectively, and the ratio of net investment
income to average net assets would have been 1.94%, 2.01%, 2.17%*, 2.28% and
2.16%*, respectively.
 
On June 1, 1995, the sub-advisory agreement between Dimensional Fund Advisors
Inc. and the Investment Manager was terminated, and the Investment Manager
assumed sole responsibility for providing the Fund with investment advisory
services.

MATCHING THE FUND TO YOUR INVESTMENT NEEDS
 
The Fund may be appropriate for a variety of investment programs. While the Fund
is not a substitute for an investment portfolio tailored to an individual's
investment needs and ability to tolerate risk, it can be used as a broad-based
"core" equity investment around which to build your overall portfolio.
- ------------------------------------------------------------
THE FUND MAY BE ESPECIALLY SUITABLE FOR LONG-TERM INVESTORS.
- ------------------------------------------------------------
 
Because the Fund will ordinarily invest in a large number of common stocks, it
may be especially appropriate for investors, including those saving for
retirement or college, with long-term investment objectives. While common stock
prices tend to rise and decline for short or extended periods, historically they
have generally risen over the long term. As a result, stocks have over time
historically provided many investors with higher returns than most alternative
securities investments.
 
INVESTMENT OBJECTIVE AND POLICIES
- ---------------------------------------------
THE FUND IS DESIGNED TO MATCH THE PERFORMANCE
OF THE SCHWAB 1000 INDEX(R).
- ---------------------------------------------
 
The Fund is a diversified investment portfolio of the Trust, an open-end
management investment company. The investment objective of the Fund is to
provide a total return that matches that of the Index, an index created to
represent the performance of publicly traded common stocks of United States
companies. The Fund's investment objective is fundamental and cannot be changed
without shareholder approval. While there is no assurance that the Fund will
achieve its investment objective, it will endeavor to do so by following the
investment policies set forth below.
- ---------------------------------------------------------
THE FUND WILL FOLLOW AN "INDEXING" OR "PASSIVE" STRATEGY.
- ---------------------------------------------------------
 
The Fund will follow an "indexing" or "passive" strategy under which stocks are
only purchased or sold in order to match the composition of the Index.
Accordingly, the Investment Manager generally will not select securities for the
Fund's investment portfolio based upon traditional economic, financial and
market analyses and/or forecasting.
- ----------------------------------------------------------
THE FUND IS MANAGED TO MINIMIZE COSTS AND TAX CONSEQUENCES
TO INCREASE SHAREHOLDERS' TOTAL RETURN.
- ----------------------------------------------------------
 
The Fund is managed to offset capital gains with capital losses in order to
minimize your capital gains tax liability. This special feature of the Fund can
make a real difference in your after-tax return.
 
The Fund has adopted a number of policies that should cause its portfolio
turnover rate to be below that experienced in many other mutual fund portfolios.
The Fund's portfolio turnover rates for the years ended August 31, 1995 and 1994
were 2% and 3%, respectively. Lower portfolio turnover acts to minimize
associated transaction costs as well as the level of current realized capital
gains. Shareholders' current tax liability for capital gains should be reduced
and their total return increased by these policies.
 
                                        6
<PAGE>   7
 
To reduce transaction costs and minimize shareholders' current capital gains tax
liability, the Fund's investment portfolio will not be automatically traded
(i.e., "rebalanced") to reflect changes in the Index. The Fund's trading
strategy is designed to further minimize transaction costs (e.g., the Fund will
generally only buy round-lots of stocks and may trade large blocks of
securities). These policies may cause a particular stock to be over- or
under-represented in the Fund relative to its Index weighting or result in its
continued ownership by the Fund after its deletion from the Index, thereby
reducing the correlation between Fund and Index composition. However, given the
diversified nature of the Fund, the Investment Manager does not expect that
these potential deviations will significantly impact the correlation between
Fund and Index performance. Moreover, the Investment Manager will only engage in
these practices to the extent that they do not have a material effect on the
Fund's ability to track the performance of the Index.
- -------------------------------------------------------------------
THE FUND WILL ATTEMPT TO BE SUBSTANTIALLY INVESTED IN INDEX STOCKS.
- -------------------------------------------------------------------
 
Under normal market conditions, the Fund will invest at least 80% of its total
assets in stocks that comprise the Index ("Index Stocks"). The Fund, however, is
not required to buy or sell securities solely because the percentage of its
assets invested in Index Stocks changes when the market value of its holdings
increases or decreases. In addition, the Fund may omit or remove an Index Stock
from its portfolio if the Investment Manager believes the stock to be
insufficiently liquid or believes the merit of the investment has been
substantially impaired by extraordinary events or financial conditions.
Moreover, to avoid any potential conflict of interest, the Fund will not
purchase securities of issuers with which it is affiliated (including The
Charles Schwab Corporation). To compensate for any Index Stocks omitted or
removed from its investment portfolio, the Fund may purchase stocks not in the
Index (which would then be considered Index Stocks for purposes of the Fund's
policy regarding the percentage of its assets to be invested in Index Stocks) if
the Investment Manager believes that their market performance is likely to
replicate that of the Index Stocks they replace.
 
It is anticipated that the Fund will be able to invest in a majority of Index
Stocks. The Fund will generally select stocks by reference to their weighting in
the Index. Thus, the Fund intends that the percentage of its assets invested in
each Index Stock will approximate the weighting of that stock in the Index.
- ------------------------------------------------------
FUND PERFORMANCE SHOULD APPROXIMATE THAT OF THE INDEX.
- ------------------------------------------------------
 
While Fund performance will not precisely match Index performance, the Fund will
attempt to maximize the correlation between its performance and that of the
Index. Factors such as the size of the Fund's portfolio, transaction costs,
management fees and expenses, brokerage commissions and fees, the extent and
timing of cash flows into and out of the Fund, the Fund's policy of minimizing
transaction costs and current capital gains tax liability, and changes in the
securities markets and the Index itself are expected by the Investment Manager
to account for any differences between Fund and Index performance.
 
                                        7
<PAGE>   8
 
- ----------------------------------------------------------
THE FUND MAY PURCHASE SECURITIES ASIDE FROM COMMON STOCKS.
- ----------------------------------------------------------
 
The value of all non-Index Stock investments may normally represent no more than
20% of the Fund's total assets. In order to accommodate cash flows resulting
from the purchase and sale of Fund shares, the Fund may invest in securities
issued or guaranteed by the U.S. Government, its agencies or instrumentalities,
and certificates of deposit, bankers' acceptances and commercial paper (which
has been rated in one of the two highest categories by a non-affiliated,
nationally recognized statistical rating organization); enter into repurchase
agreements collateralized by these instruments; and purchase shares of other
investment companies that invest primarily in any of the securities described
above. In the aggregate, no more than 10% of the Fund's total assets may be
invested in other investment companies, and an investment in any one investment
company will be limited to 5% of total Fund assets. Because other investment
companies employ an investment adviser and other service providers, such
investments by the Fund may cause shareholders to bear duplicative fees. The
Investment Manager will charge no management fees attributable to any Fund
assets invested in other investment companies. (See "Investment Restrictions" in
the Statement of Additional Information.)
 
The Fund may also purchase futures contracts on stocks and stock indices,
options contracts (including options on futures contracts), equity index
participations and index participation contracts to accommodate cash flows or in
anticipation of taking a market position when, in the opinion of the Investment
Manager, available cash balances do not permit economically efficient Index
Stock purchases. Moreover, the Fund may sell futures and options to "close out"
futures and options it may have purchased or to protect against a decrease in
the price of securities it owns but intends to sell. The Fund will not invest
more than 5% of its total assets in equity index participations and may enter
into futures contracts and options thereon provided that the aggregate deposits
required on these contracts do not exceed 5% of the Fund's total assets. Futures
contracts and options may be used to maintain cash reserves while simulating
full investment; to facilitate trading; or to seek higher investment returns or
simulate full investment when a futures contract is priced more attractively or
is otherwise considered more advantageous than the underlying security or index.
 
Futures contracts and options pose certain risks. The primary risks associated
with the use of futures contracts and options include: imperfect correlation
between the change in market value of the securities held by the Fund and the
prices of futures contracts and options, and possible lack of a liquid secondary
market for a futures contract and the resulting inability to close a futures
position prior to its maturity date. The risk of imperfect correlation will be
minimized by investing only in those contracts whose behavior is expected to
resemble that of the Fund's underlying securities. The risk that the Fund will
be unable to close out a futures position will be minimized by entering into
such transactions on a national exchange with an active and liquid secondary
market.
 
The risk of loss in trading futures and options contracts in some strategies can
be substantial, due both to the low margin deposits required and the extremely
high degree of leverage that can be involved in futures and options pricing. As
a result, a relatively small price movement in a futures or options contract may
result in immediate and substantial loss (or gain) to the investor. While
futures contracts and options can be used as leveraged instruments, the Fund may
not use futures contracts or options
 
                                        8
<PAGE>   9
 
to leverage its portfolio. When investing in futures and options contracts, the
Fund will segregate cash, cash-equivalents or liquid, high quality debt
instruments in the amount of the underlying obligation.
- ---------------------------------------------------------------
THE FUND MAY LEND ITS SECURITIES TO GENERATE ADDITIONAL INCOME.
- ---------------------------------------------------------------
 
To increase its income, the Fund may lend securities from its portfolio 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 collateralized by
cash, letters of credit or U.S. Government securities equal at all times to 100%
of the loaned securities' market value plus accrued interest.
 
THE SCHWAB 1000 INDEX(R)
- -------------------------------------
THE INDEX HAS SET INCLUSION CRITERIA.
- -------------------------------------
 
To be included in the Index, a company must satisfy all of the following
criteria:
 
1. it must be an "operating company" (i.e., not an investment company)
   incorporated in the United States, its territories or possessions;
 
2. a liquid market for its common shares must exist on the New York Stock
   Exchange (the "Exchange"), American Stock Exchange or the NASDAQ/NMS; and
 
3. its market value must place it among the top 1,000 such companies as measured
   by market capitalization.
 
A particular stock's weighting in the Index is based on its relative total
market value (i.e., its market price per share multiplied by the number of
shares outstanding), divided by the total market value of the Index. As of
December 15, 1995, the aggregate market capitalization of Index Stocks was
approximately $5.4 trillion.
- -----------------------------------------
SCHWAB DEVELOPED AND MAINTAINS THE INDEX.
- -----------------------------------------
 
The Index, which as of December 15, 1995 represented approximately 85% of the
total market value of all publicly traded United States companies, as
represented by the Wilshire 5000 Index, was developed and is maintained by
Schwab to represent the total return of publicly traded common stocks of United
States companies and serve as a standard of comparison for Fund performance.
Schwab receives no compensation from the Fund for maintaining the Index.
- ------------------------------------------------------
SCHWAB CALCULATES AND REPORTS INDEX PERFORMANCE DAILY.
- ------------------------------------------------------
 
Index performance (i.e., the market value of all Index Stocks) is calculated and
made available each Business Day by Schwab. Index total return is computed
monthly (using beginning of month capitalization weightings and assuming
reinvestment of dividends) and may be reported from time to time to Fund
shareholders.
 
                                        9
<PAGE>   10
 
- ---------------------------------------------------------
SCHWAB PERIODICALLY UPDATES THE COMPOSITION OF THE INDEX.
- ---------------------------------------------------------
 
Schwab reviews and, as necessary, revises the list of companies whose securities
are included in the Index at least semi-annually. Companies known by Schwab to
meet or no longer meet the inclusion criteria will be added or deleted as
appropriate. Schwab will also modify the Index as necessary to account for
corporate actions (e.g., new issues, repurchases, stock dividends/splits,
tenders, mergers, swaps, spin-offs or Chapter 11 bankruptcy filings made because
of a company's inability to continue operating as a going concern). Schwab may
change Index inclusion criteria if it determines that doing so would cause the
Index to be more representative of the domestic equity market. In the future,
the Trust's Board of Trustees, subject to shareholder approval, may select
another index should it decide that taking such action would be in the best
interests of Fund shareholders.
 
MANAGEMENT OF THE FUND
 
Responsibility for overall management of the Fund rests with the trustees and
officers of the Trust. Professional investment management for the Fund is
provided by the Investment Manager, Charles Schwab Investment Management, Inc.,
101 Montgomery Street, San Francisco, CA 94104. In addition to maintaining the
Index and providing day-to-day portfolio management of the Fund, the Investment
Manager provides general investment advice regarding the Fund's investment
strategies, and performs expense management, accounting and recordkeeping, and
other administrative services necessary to the operation of the Fund. 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 mutual
funds in the SchwabFunds Family(R), a family of 21 mutual funds. As of December
15, 1995, the SchwabFunds had aggregate net assets of approximately $31 billion.
 
Pursuant to separate agreements, Charles Schwab & Co., Inc. ("Schwab" or the
"Transfer Agent"), 101 Montgomery Street, San Francisco, CA 94104, serves as
shareholder services 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 information),
responding to daily inquiries, and effecting the transfer of Fund shares, and
facilitating effective cash management of shareholder Schwab account balances.
It also furnishes such office space and equipment, telephone facilities,
personnel and informational literature distribution as is necessary and
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 3.3 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 and the Investment Manager, which was formed in 1989, are wholly-owned
subsidiaries 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 November 30, 1995, the beneficial owner of approximately
20.1% of the outstanding shares of that corporation. Mr. Schwab may be deemed to
be a controlling person of Schwab and the Investment Manager.

Geri Hom is the portfolio manager of the Fund. She joined Schwab in March 1995
as Portfolio Manager -- Equities and currently manages the three Schwab index
funds and co-manages the three Schwab Asset Director(R) Funds with over $1.4
billion in assets. For four years prior to joining Schwab, she was a Principal
for Wells Fargo Nikko Investment Advisors. She was Vice President and Manager of
the Domestic Equity Portfolio Management Group for Wells Fargo Nikko for seven
years prior to that.
 
Stephen B. Ward, Senior Vice President and Chief Investment Officer, also
participates in the management of the Fund. Prior to April 1991, Mr. Ward was
Vice President and Portfolio Manager for Federated Investors.
 
Please see the Fund's Annual Report to Shareholders for the fiscal year ended
August 31, 1995 for a discussion by the Investment Manager of the Fund's
performance.
 
FEES AND EXPENSES. Pursuant to its Investment Advisory and Administration
Agreement with the Trust, the Investment Manager receives from the Fund a
graduated annual fee, payable monthly, of 0.30% of the Fund's average daily net
assets not in excess of $500 million and 0.22% of such assets over $500 million.
The Investment Manager has agreed to waive the Fund's management fee in excess
of 0.20% of the Fund's average daily net assets through at least April 30, 1996.
In addition, the Investment Manager and Schwab guarantee that total fund
operating expenses will not exceed 0.49% of the Fund's average daily net assets
through at least April 30, 1996. This expense limit will serve to maintain or
lower the Fund's expenses and thus maintain or increase the Fund's total return
to shareholders. For the year ended August 31, 1995, the Fund paid investment
management fees of 0.26% and total operating expenses of 0.54% of the Fund's
average daily net assets.
 
For the transfer agency and shareholder services provided under its Transfer
Agency and Shareholder Service Agreements with the Trust, Schwab receives an
annual fee, payable monthly, of 0.05% and 0.20%, respectively, of the Fund's
average daily net assets. PNC Bank, N.A. is the Fund's custodian (the
"Custodian"). The Investment Manager, Schwab and the Custodian may each reduce
its fees from time to time.
 
The Trust pays the expenses of its operations, including the fees and expenses
of independent accountants, legal counsel and custodian; the costs of
calculating net asset values, brokerage commissions or transaction costs; taxes;
registration fees; and the fees and expenses of qualifying the Trust and its
shares for distribution. In addition, the Trust will incur and pay fees in
connection with the establishment and maintenance of "sweep" accounts through
which the Fund may make regular investments in other investment companies. The
expenses will generally be allocated among the Trust's investment portfolios on
the basis of relative net assets at the time the expense is incurred. However,
expenses directly attributable to a particular Fund will be charged to that
Fund.
 
PORTFOLIO BROKERAGE. When placing orders for the Fund's securities transactions,
the Investment Manager will use its judgment to obtain best price and execution.
The full range and quality of brokerage services available are considered in
making these determinations. For securities transactions in which Schwab is not
a principal, the Investment Manager may use Schwab to execute the
 
                                       11
<PAGE>   12
 
Fund's transactions when it reasonably believes that commissions (or prices)
charged and transaction quality will be at least comparable to those available
from other qualified brokers or dealers.
 
DISTRIBUTIONS AND TAXES
- -------------------------------------------------
THE FUND WILL DECLARE AND PAY DIVIDENDS ANNUALLY.
- -------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS. The Fund will distribute substantially all of
its net investment income and net capital gains, if any, on an annual basis, as
determined by the Trust's Board of Trustees.
 
The value of your shares reflects any net investment income or net capital gains
that the Fund has earned but not yet distributed, so their value will be reduced
when distributions are paid. If you elect to receive these distributions in
cash, the value of your Fund holdings as a whole will decrease. If you choose to
reinvest your distributions, the reduced value of your shares will be offset by
the value of new shares purchased with reinvested distributions.
 
FEDERAL TAX INFORMATION. The Fund is treated as a separate entity for tax
purposes, has elected to be treated as a regulated investment company under
Subchapter M of 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 substantially all of its net investment income
and net capital gains to shareholders on an annual basis, and will meet certain
other requirements. Such qualification will relieve the Fund of liability for
federal income tax to the extent its earnings are so distributed.
 
Dividends paid by the Fund from net investment income and distributions from the
Fund's net short-term capital gains in excess of any net long-term capital
losses, whether received in cash or reinvested, generally will be taxable as
ordinary income. For corporate investors in the Fund, dividend distributions
designated by the Fund to be from dividends received from qualifying domestic
corporations will be eligible for the 70% corporate dividends-received deduction
to the extent they would qualify if the Fund were a regular corporation.
Distributions received from the Fund designated as long-term capital gains (net
of capital losses), whether received in cash or reinvested, will be taxable as
long-term capital gains without regard to the length of time a shareholder owned
shares in the Fund. However, any loss on the sale or exchange of shares held for
six months or less shall, to the extent of any long-term capital gain
distributions received with respect to such shares, be treated as a long-term
capital loss. If a shareholder is not subject to income tax, generally the
shareholder will not be taxed on amounts distributed by the Fund.
 
Records of dividends and other distributions, purchases and redemptions will be
reflected on shareholders' Schwab account statements. The Fund will notify
shareholders at least annually as to the nature of all distributions made during
the taxable year, including amounts qualifying as dividends and capital gains
distributions.
 
The foregoing is only a brief summary of the federal income tax considerations
affecting the Fund and its shareholders. The discussion of taxes set forth above
is included for general information purposes only. Prospective investors in the
Fund should consult their tax advisers with specific reference to their own tax
situations.

SHARE PRICE CALCULATION
- ------------------------------------------------
THE FUND SELLS ITS SHARES FREE OF SALES CHARGES.
- ------------------------------------------------
 
The price of the Fund's shares on any given day is its "net asset value" or NAV.
For any given day, this figure is computed by dividing the total market value of
the Fund's investments and other assets on that day, less any liabilities, by
the number of Fund shares outstanding. The net asset value per share of the Fund
is determined on each day the Exchange is open for trading at 4:00 p.m., Eastern
time. The Fund's net asset value will fluctuate, and Fund shares are not insured
against reduction in net asset value. Purchase or redemption orders and exchange
requests will be executed at the NAV next determined after receipt and
verification by Schwab's Mutual Fund Transfer Agency Department. (See "Share
Price Calculation" in the Statement of Additional Information.)
 
The Fund values its portfolio securities based on their market value. Each
security held by the Fund which is listed on a securities exchange and for which
market quotations are available is valued at the last quoted sale price for a
given day, or if a sale is not reported for that day, at the mean between the
most recent quoted bid and asked prices. Price information on each listed
security is taken from the exchange where the security is primarily traded.
Unlisted securities for which market quotations are readily available are valued
at the mean between the most recent bid and asked prices. Other assets for which
no quotations are readily available (including any restricted securities) are
valued at fair value as determined in good faith by the Investment Manager
pursuant to Board of Trustees guidelines. Securities may be valued on the basis
of prices provided by pricing services when such prices are believed to reflect
fair market value.
 
HOW THE FUND SHOWS PERFORMANCE
- ------------------------------------------------------------------
THE FUND'S PERFORMANCE MAY BE ADVERTISED IN TERMS OF TOTAL RETURN.
- ------------------------------------------------------------------
 
From time to time the Fund may advertise its total return. Performance figures
are based upon historical results and are not intended to indicate future
performance.
 
The Fund's total return measures its overall change in value over a period,
including share price movements, and assumes all dividends and capital gains
have been reinvested. Average annual total return reflects the hypothetical
annually compounded return mandated by the SEC. Other reported total return
figures may differ in that they may report non-standard periods or represent
aggregate or cumulative return over a stated length of time.
 
The Fund's performance may be compared to that of other mutual funds tracked by
mutual fund rating services, various indices of investment performance
(including the Index), United States Treasury obligations, bank certificates of
deposit, the Consumer Price Index, corporate bonds and other investments for
which reliable performance data is available. The Fund's performance may also be
compared to averages, performance rankings, or other information prepared by
Lipper Analytical Services, Inc. and Morningstar, Inc.
 
Additional performance information is available in the Trust's Annual Report to
Shareholders, which is available free of charge by calling 800-2 NO-LOAD, or
from your local Schwab office.

TAX-ADVANTAGED RETIREMENT PLANS
- -------------------------------------------------------------
RETIREMENT PLANS OFFER EXCELLENT TAX ADVANTAGES, AND THE FUND
MAY BE AN ESPECIALLY SUITABLE INVESTMENT FOR THEM.
- -------------------------------------------------------------
 
Schwab offers tax-advantaged retirement plans for which the Fund may be a
particularly appropriate investment. 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 IRAs with balances of $10,000 or more by September 15, 1996 will not be
charged Schwab's $29 annual IRA account fee for the life of the account.
 
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, 24 hours a day for more information.
 
GENERAL INFORMATION
 
ABOUT THE TRUST. The Trust was organized as a business trust under the laws of
Massachusetts on October 26, 1990 and may issue an unlimited number of shares of
beneficial interest in one or more investment portfolios or series ("Series").
Currently, shares of seven Series are offered. The Board of Trustees may
authorize the issuance of shares of additional Series if it deems it desirable.
Shares within each Series will have equal, noncumulative voting rights and equal
rights as to dividends, assets and liquidation of such Series.
 
The Trust 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 or removing
trustees, changing fundamental policies, or approving an investment advisory
agreement. In addition, a Trustee may be removed by shareholders at a special
meeting called upon written request by shareholders owning at least 10% of the
outstanding shares of the Trust. 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
Investment Company Act of 1940, as amended, such as for the election of
trustees.

SHAREHOLDER SERVICE. You may place 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, 24 hours a day, 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 transactions may be difficult 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.
 
To assist in minimizing administrative costs, share certificates will not be
issued. Records regarding share ownership are maintained by the Transfer Agent.
 
You may purchase shares through an account maintained with Schwab or through any
other entity which has been designated by Schwab. The following information
regarding the purchase, exchange, and redemption of Fund shares through a Schwab
account relates solely to transactions through Schwab accounts and should not be
read to apply to transactions through other designated entities. For more
information, see "Purchase and Redemption of Shares" in the Statement of
Additional Information or contact such designated entity.
 
HOW TO PURCHASE SHARES
- ---------------------------------------------
YOU MAY PURCHASE SHARES OF THE FUND THROUGH A
SCHWAB, IRA, TRUST, OR KEOGH ACCOUNT.

payment for shares must be made directly to Schwab. The Securities Investor
Protection Corporation ("SIPC") will provide account protection, in an amount up
to $500,000 for securities, including Fund shares that you hold in a Schwab

you already have a Schwab account, you 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, or contacting your local Schwab office) and mail or deliver it to your

custodial accounts). A quarterly fee of $7.50 will be charged on Schwab
brokerage 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 at least
one commissionable trade within the last six months, or if the shareholder's
combined account balances at Schwab total $10,000 or more.
 
Schwab currently imposes no fee for opening a Schwab One(R) account with a
minimum of $5,000 account equity. Schwab One accounts containing less than
$5,000 account equity are subject to a fee of $5 per month imposed by Schwab if
there have been fewer than two commissionable trades within the last twelve
months.
- -------------------------------------------------------------
YOUR INITIAL FUND INVESTMENT MAY BE AS LOW AS $1,000.
ADDITIONAL SHARE PURCHASES CAN BE MADE FOR AS LITTLE AS $100.
- -------------------------------------------------------------
 
MINIMUM FUND INVESTMENT REQUIREMENTS. Your initial investment in the Fund may be
as low as $1,000 ($500 for IRAs, certain other retirement plans and custodial
accounts). The minimum subsequent investment is $100. These requirements may be
reduced or waived on certain occasions. (See "Purchase and Redemption of Shares"
in the Statement of Additional Information.)
 
Schwab reserves the right to waive these minimums for clients of Schwab
Institutional and The Charles Schwab Trust Company and for certain
tax-advantaged retirement plans.
- -------------------------------------------------------
SHARES WILL BE PURCHASED AFTER YOU HAVE FUNDS AVAILABLE
IN YOUR SCHWAB ACCOUNT.
- -------------------------------------------------------
 
WHEN AND AT WHAT PRICE SHARES WILL BE PURCHASED. You must have funds available
in your Schwab account in order to purchase Fund shares through your Schwab
account. If funds (including those transmitted by wire) are received by Schwab
before the time the daily net asset value is calculated (normally 4:00 p.m.,
Eastern time), they will be available for investment on the day of receipt. If
funds arrive after that time, they will be available for investment the next
Business Day.

options listed below when you first become a shareholder in the Fund. If you
already are a Fund shareholder and wish to change your distribution option,
please call your local Schwab office for assistance.
 
1. AUTOMATIC REINVESTMENT: Both income dividends and any capital gains

   you must choose this distribution option for this Fund.
 
                                       17
<PAGE>   18
 
2. CASH DIVIDENDS/REINVESTED CAPITAL GAINS: Income dividends will be paid in
   cash, and capital gains will be reinvested in additional shares.
 
3. ALL CASH: Income dividends and any capital gains distributions will both be
   paid in cash.
 
Dividends and distributions subject to reinvestment will be invested at the net
asset value next determined after their record date. Cash distributions will be
credited to your Schwab account and will be held there or mailed to you,
depending on the account standing instructions applicable to your account. 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 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
Schwab account should his or her investment check be returned because of
insufficient or uncollected funds or a stop payment order.
 
HOW TO SELL OR EXCHANGE SHARES
- ------------------------------------------------
FUND SHARES MAY BE EXCHANGED FOR SHARES OF OTHER
FUNDS OR CLASSES OF SHARES SPONSORED BY SCHWAB.
- ------------------------------------------------
 
SALE OF SHARES. Shares will be redeemed at the net asset value per share next
determined after receipt and verification by Schwab's Mutual Fund Transfer
Agency Department of proper redemption instructions, as set forth on the
following pages. Payment for redeemed shares will be credited directly to your
Schwab account no later than 7 days after Schwab's Mutual Fund Transfer Agency
Department receives your redemption instructions in proper form. Redemption
proceeds will then be held there or mailed to you depending on the account
standing instructions you selected. For information on how to wire funds from
your Schwab account to your bank, see "Other Important Information -- Wire
Transfers to Your Bank." 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 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. (See "Purchase and Redemption of Shares" in the Statement of
Additional Information.)
 
EXCHANGE OF SHARES. The exchange privilege allows you to exchange your
SchwabFunds(R) shares for shares of any other SchwabFunds(R) 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 involves the
redemption of Fund shares and the purchase of shares of any SchwabFunds of your
 
                                       18
<PAGE>   19
 
choice. An exchange of shares will be treated as a sale and purchase of 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. The Fund reserves the right on 60 days' written notice to
modify, limit or terminate the exchange privilege.
 
EARLY WITHDRAWAL FEE PAID TO THE FUND. The Fund is meant to be a long-term
investment. Frequent trading in Fund shares by short-term investors increases
the Fund's costs. To offset the costs of short-term trading and to ensure that
long-term investors do not bear these costs, the Fund assesses a 0.50% (one-half
of one percent) early withdrawal fee upon redemption or exchange proceeds
attributable to shares purchased and held less than six months. To benefit Fund
shareholders directly, the early withdrawal fee is paid directly to the Fund and
does not apply to the redemption or exchange of shares acquired through
reinvestment of dividends or capital gains. Solely for purposes of calculating
the amount (if any) of the early withdrawal fee, shares will be treated as
redeemed on a "first-in first-out basis," except that shares acquired through
dividend reinvestment will be treated as redeemed first. This method of
calculating the fee should result in the lowest total early withdrawal fee. The
Fund reserves the right to waive this fee for certain clients of Schwab
Institutional and The Charles Schwab Trust Company and for certain
tax-advantaged retirement plans.

SCHWAB AUTOMATIC INVESTMENT PLAN
- ---------------------------------------------------------------
THE FREE SCHWAB AUTOMATIC INVESTMENT PLAN IS A FAST, CONVENIENT
WAY TO MAKE REGULAR INVESTMENTS IN THE FUND.
- ---------------------------------------------------------------
 
Schwab's Automatic Investment Plan ("AIP") allows you to make periodic
investments in non-money market SchwabFunds(R) (and certain other funds
available through Schwab) automatically and conveniently. You can make automatic
investments in any amount, from $100 to $50,000, once you meet the Fund's
investment minimum. Automatic investments are made from your Schwab account, and
you may select from the following methods to make automatic investments: using
the uninvested cash in your Schwab account; using the proceeds of redemption of
shares of the Schwab Money Fund linked to your Schwab account; or using the
Schwab MoneyLink(R) Transfer Service. As long as you are purchasing the Fund's
shares through AIP, all dividends and distributions paid to you by the Fund must
be reinvested in additional shares of that Fund. For more detailed information
about this service, or to establish your AIP, call your local Schwab office or
800-2 NO-LOAD, 24 hours a day.
 
OTHER IMPORTANT INFORMATION
 
MINIMUM BALANCE AND ACCOUNT REQUIREMENTS. Due to the relatively high cost of
maintaining accounts with smaller holdings, the Fund reserves the right to
redeem a shareholder's shares if, as a result of redemptions, the aggregate
value of a shareholder's holdings in that Fund drops below the Fund's $500
minimum balance requirement ($250 in the case of IRAs, other retirement plans
and custodial accounts). Shareholders will be notified in writing 30 days before
the Fund takes such action to allow them to increase their holdings to at least
the minimum level. Fund shares will be automatically redeemed should the Schwab
account in which the shares are carried be closed.
 
CONSOLIDATED MAILINGS. In an effort to reduce 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 SchwabFunds 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 branch for additional information. A $15 service fee will be charged
against your Schwab account for each wire sent.

KEY FEATURES OF THE FUNDS
 
PERFORMANCE. The investment objective of both Funds is to attempt to provide a
high level of current income consistent with preservation of capital by
investing primarily in securities issued or guaranteed by the United States
Government, its agencies or instrumentalities and repurchase agreements covering
these securities. Although the Funds will invest primarily in securities
guaranteed by the U.S. Government, its agencies or instrumentalities, neither
Fund is backed by the U.S. Government. (See "Investment Objectives, Policies and
Risk Considerations.")
 
EFFECT OF PORTFOLIO MATURITIES ON YIELDS. Securities with longer maturities have
a greater risk of fluctuation of principal value than money market instruments.
High-quality money market instruments reflect short-term interest rates with
relatively little risk of fluctuation of principal value. The Short/Intermediate
Fund seeks to provide higher yields than money market instruments by investing
in securities with a dollar weighted average portfolio maturity not to exceed
five years. The Long-Term Fund seeks to provide even higher yields by investing
in securities with a dollar weighted average portfolio maturity greater than 10
years. (See "Matching the Funds to Your Investment Needs.")
 
MINIMIZATION OF SHARE PRICE FLUCTUATION. The Short/Intermediate Fund is managed
in an effort to minimize fluctuations in the value of its shares. The average
dollar weighted portfolio maturity not to exceed five years is designed to
achieve this goal. The Short/Intermediate Fund's emphasis on capital
preservation may at times cause the Fund not to provide the same yield and total
return as other funds invested in longer-term or lower quality bonds.
 
CREDIT SAFETY THROUGH A GOVERNMENT PORTFOLIO. Both Funds normally will invest
only in Government securities, which are usually considered to be among the
safest of instruments. (See "Investment Objectives, Policies and Risk
Considerations.")
 
MONTHLY DIVIDENDS. Dividends on each Fund's shares are declared daily and paid
monthly, unlike many individual Government securities which generally pay
interest semi-annually. Additionally, unlike interest paid on Government
securities, shareholders can reinvest dividends paid on their Fund shares. (See
"Distributions and Taxes.")
 
LOW MINIMUM INVESTMENT. Investors can begin their investment program with as
little as $1,000. Subsequent investments can be made with only $100. (See "How
to Purchase Shares.")
 
PROFESSIONAL MANAGEMENT. Charles Schwab Investment Management, Inc. (the
"Investment Manager"), currently provides investment management services to the
mutual funds in the SchwabFunds Family(R), a family of 21 mutual funds with over
$31 billion in assets as of December 15, 1995. (See "Management of the Funds.")
 
LOW COST INVESTING. Each Fund brings a low cost approach to investing with:
 
     - no sales or transaction fees;
     - no 12b-1 fees or contingent deferred sales charges;
     - a portion of the Short/Intermediate Fund's management fee waived through
       April 30, 1996 for potentially higher returns;
     - all of the Long-Term Fund's management fee waived through April 30, 1996
       for potentially higher returns;
     - a commitment by the Investment Manager and Schwab to absorb operating
       expenses of the Short/Intermediate Fund in excess of 0.49% of the Fund's
       average daily net assets at least through April 30, 1996 (see "Management
       of the Funds"); and
     - a commitment by the Investment Manager and Schwab to absorb all of the
       operating expenses of the Long-Term Fund at least through April 30, 1996
       (see "Management of the Funds").

Fund has been restated to reflect a reduction by the Investment Manager which is
guaranteed through at least April 30, 1996. If there were no such reductions,
the management fee for the Short/Intermediate Fund and the Long-Term Fund would
be 0.41% of each Fund's average daily net assets.
 
2 You may be charged a fee if applicable minimum balances are not maintained in
your Schwab brokerage account or Schwab One(R) account. (See "How to Purchase
Shares -- Schwab Account Minimums and Associated Fees.") Schwab Individual
Retirement Accounts with balances of $10,000 or more by September 15, 1996 will
not be 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 "Tax-
Advantaged Retirement Plans.")
 
3 This amount has been restated to reflect the guarantee by the Investment
Manager and Schwab that, through at least April 30, 1996, the total operating
expenses of the Short/Intermediate Fund will not exceed 0.49% of the Fund's
average daily net assets. Without a similar guarantee, which was in effect for
the fiscal year ended August 31, 1995, other expenses and total fund operating
expenses would have been 0.40% and 0.81%, respectively, of the Fund's average
daily net assets.
 
4 This amount reflects the guarantee by the Investment Manager and Schwab that,
through at least April 30, 1996, the Investment Manager and Schwab will absorb
all the Long-Term Fund's operating expenses. Without this guarantee, which was
in effect for the fiscal year ended August 31, 1995, other expenses and total
fund operating expenses would have been 0.77% and 1.18%, respectively, of the
Fund's average daily net assets.
 
EXAMPLES. You would pay the following expenses on a $1,000 investment in each
Fund, assuming (1) a 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 FUNDS WILL BEAR DIRECTLY OR
INDIRECTLY. This example reflects the guarantee by the Investment Manager and
Schwab that the total operating expenses of each Fund will not exceed the
amounts specified for the time periods referred to in notes (3) and (4) above.
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

Note: The Investment Manager and Schwab have reduced a portion of their fees and
absorbed certain expenses in order to limit each 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 Schwab
Short/Intermediate Government Bond Fund for the periods ended August 31, 1995,
1994, 1993, December 31, 1992 and 1991 would have been .81%, .81%, .84%*, .89%
and 1.47%*, respectively, and the ratio of net investment income to average net
assets would have been 5.88%, 5.07%, 5.04%*, 5.32% and 5.02%*, respectively.
With respect to the Schwab Long-Term Government Bond Fund the ratio of expenses
to average net assets for the periods ended August 31, 1995, 1994 and 1993 would
have been 1.18%, 2.19% and 19.19%*, respectively, and the ratio of net

MATCHING THE FUNDS TO YOUR INVESTMENT NEEDS
- --------------------------------------------
THE FUNDS MAY BE SUITABLE FOR RISK-SENSITIVE
INVESTORS SEEKING INCOME.
- --------------------------------------------
 
The Funds may be appropriate for a variety of investment programs. While the
Funds are not a substitute for an investment portfolio tailored to an
individual's investment needs and ability to tolerate risk, they can serve as
components of an investor's long-term program to accumulate assets for
retirement, college tuition, or other major goals.
 
Because the Funds will ordinarily invest primarily in U.S. Government securities
and because the Short/Intermediate Fund will be managed in an effort to minimize
fluctuations in its share price, the Short/Intermediate Fund (and to a lesser
degree, the Long-Term Fund) may be appropriate for investors, including those
who have retired, who desire to receive monthly dividend payments from a fund
whose objective is to seek above average returns while minimizing their exposure
to principal fluctuations. Investors should note, however, that the principal
value of shares of the Long-Term Fund may be subject to greater fluctuation than
the value of shares of the Short/Intermediate Fund resulting from the longer
maturities of the securities held by the Long-Term Fund.
 
INVESTMENT OBJECTIVES, POLICIES AND RISK CONSIDERATIONS
- ---------------------------------------------------------
THE FUNDS ARE DESIGNED TO PROVIDE A HIGH LEVEL OF CURRENT
INCOME CONSISTENT WITH PRESERVATION OF CAPITAL.
- ---------------------------------------------------------
 
Both Funds are investment portfolios of the Trust, a no-load, open-end,
management investment company. The investment objective of each Fund is to
provide a high level of current income consistent with preservation of capital.
Each Fund's investment objective, along with certain investment restrictions
adopted by each Fund (see "Investment Restrictions" in the Statement of
Additional Information), 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"). While there is no assurance
that either Fund will achieve its investment objective, each will endeavor to do
so by following the investment policies set forth below.
- --------------------------------------------------------------
EACH FUND WILL INVEST PRIMARILY IN U.S. GOVERNMENT SECURITIES.
- --------------------------------------------------------------
 
Each Fund will invest primarily in securities issued or guaranteed by the United
States Government, its agencies, or instrumentalities, and repurchase agreements
covering these securities. The Funds will attempt to invest 100% of their total
assets in the foregoing instruments and may also invest in related options and
futures contracts. Under normal market conditions, each Fund will invest at
least 65% of its total assets in bonds, which include bonds, notes, debentures,
mortgage-related securities, stripped government securities, and zero coupon
obligations.
 
U.S. Government Securities include: bills, bonds, stripped government
securities, and other debt securities, differing as to maturity and rates of
interest, that are issued by and are direct obligations of the U.S. Treasury and
other securities that are issued or guaranteed as to principal and interest by
the U.S. Government or by its agencies or instrumentalities that include, but
are not limited to,
 
                                        6
<PAGE>   31
 
Government National Mortgage Association ("GNMA"), Federal Farm Credit Banks,
Federal Home Loan Banks, Federal Home Loan Mortgage Corporation ("FHLMC"), and
Federal National Mortgage Association ("FNMA"). U.S. Government Securities are
generally viewed by the Investment Manager as being among the safest of debt
securities with respect to the timely payment of principal and interest (but not
with respect to any premium paid on purchase), but generally bear a lower rate
of interest than corporate debt securities. However, they are subject to market
risk like other debt securities, and therefore a Fund's shares can be expected
to fluctuate in value. In addition, each Fund may invest in principal or
interest only portions of U.S. Government Securities that have been separated
(stripped). Stripped securities are usually sold separately in the form of
receipts or certificates representing undivided interests in the stripped
portion. Stripped securities may be more volatile than non-stripped securities.
 
Depending on market conditions, the Funds may invest a substantial portion of
their assets in mortgage-backed debt securities issued by GNMA, FNMA, and FHLMC.
Securities issued by GNMA represent an interest in a pool of mortgages insured
by the Federal Housing Administration or the Farmers Home Administration, or
guaranteed by the Veterans Administration. Securities issued by FNMA and FHLMC,
U.S. Government-sponsored corporations, also represent an interest in a pool of
mortgages.
 
The timely payment of principal and interest on GNMA securities is guaranteed by
GNMA and backed by the full faith and credit of the U.S. Treasury. FNMA
guarantees full and timely payment of interest and principal on FNMA securities.
FHLMC guarantees timely payment of interest and ultimate collection of principal
on FHLMC securities. FNMA and FHLMC securities are not backed by the full faith
and credit of 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 greater risk of loss of principal and interest.
 
Mortgage-backed debt securities, such as those issued by GNMA, FNMA, and FHLMC,
are of the "modified pass-through type," which means the interest and principal
payments on mortgages in the pool are passed through to investors. During
periods of declining interest rates, there is increased likelihood that the
underlying mortgages will be prepaid, with a resulting loss of the full-term
benefit of any premium paid by a Fund on purchase of such securities. In
addition, the proceeds of prepayment would likely be invested at lower interest
rates. Also, prepayments of mortgages which underlie securities purchased at a
premium may not have been fully amortized at the time the obligation is repaid.
As a result of these principal payment features, mortgage-backed securities are
generally more volatile investments than other U.S. Government Securities.
 
The Funds may also invest in other types of U.S. Government Securities,
including collateralized mortgage obligations ("CMOs") issued by U.S. Government
agencies or instrumentalities. A CMO is a security backed by a portfolio of
mortgages or mortgage-backed securities held under an indenture. The issuer's
obligation to make interest and principal payments is secured by the underlying
portfolio of mortgages or mortgage-backed securities. CMOs are issued with a
number of classes or series which have different maturities and which may
represent interests in some or all of the interest or
 
                                        7
<PAGE>   32
 
principal on the underlying collateral or a combination thereof. CMOs of
different classes are generally retired in sequence as the underlying mortgage
loans in the mortgage pool are repaid. In the event of sufficient early
prepayments on such mortgages, the class or series of CMO first to mature
generally will be retired prior to its maturity. Thus, the early retirement of a
particular class or series of CMO held by a Fund would have the same effect as
the prepayment of mortgages underlying a mortgage-backed pass-through security.
 
The Funds may also enter into repurchase agreements. A repurchase agreement
involves a sale of securities to a Fund with the concurrent agreement of the
seller (bank or securities dealer) to repurchase the securities within a
specified time at a higher price or at the same price plus an amount equal to an
agreed upon interest rate. In the event of a bankruptcy or other default of a
seller of a repurchase agreement, a Fund could experience both delays in
liquidating and losses. Neither Fund may invest more than 10% of its net assets
in repurchase agreements maturing in more than seven days and other illiquid
securities.
 
Each Fund may also purchase shares of other no-load investment companies,
including those managed by the Investment Manager. These purchases will be
subject to the limitations imposed by the 1940 Act, and we will only make these
purchases after obtaining any required regulatory approvals. Investment in other
investment companies may cause you to bear duplicative fees for certain
services. The Investment Manager will charge no management fees attributable to
Fund assets that are invested in other investment companies. (See "Investment
Restrictions" in the Statement of Additional Information.")
 
Under normal market conditions, the Short/Intermediate Fund seeks to maintain a
dollar-weighted average portfolio maturity not exceeding five years, and the
Long-Term Fund seeks to maintain a dollar-weighted average portfolio maturity in
excess of ten years. Both Funds will be managed to attempt to minimize
fluctuations in the value of their shares by concentrating on securities whose
prices are anticipated to be relatively less sensitive to changes in broad based
interest rates.
 
The frequency of portfolio transactions, a Fund's turnover rate, will vary from
year to year depending upon market conditions and purchase and redemption
patterns of each Fund's shareholders. Typically, funds with higher turnover tend
to generate higher capital gains and transaction costs. The Short/Intermediate
Fund had portfolio turnover rates for the years ended August 31, 1995 and 1994
of 203% and 91%, respectively. The Long-Term Fund had portfolio turnover rates
for the years ended August 31, 1995 and 1994 of 240% and 123%, respectively. The
Investment Manager's efforts to reposition each Fund's portfolio in an
environment of steadily falling interest rates was the primary factor for each
Fund's increased portfolio turnover in 1995.
- -----------------------------------------------------
THE FUNDS MAY UTILIZE FUTURES AND OPTIONS STRATEGIES.
- -----------------------------------------------------
 
Each Fund may also purchase futures contracts on U.S. Government Securities and
any index comprised of such securities as well as options contracts (including
options on futures contracts), to accommodate cash flows or in anticipation of
taking a market position when, in the opinion of the Investment Manager,
available cash balances do not permit economically efficient purchases.
Moreover, each Fund may sell futures and options to "close out" futures and
options it may have purchased or to

 
                                        8
<PAGE>   33


protect against a decrease in the price of securities it owns but intends to
sell. Each Fund may enter into futures contracts and options thereon provided
that the aggregate deposits required on these contracts do not exceed 5% of the
Fund's total assets. Futures contacts and options may be used to maintain cash
reserves while simulating full investment; to facilitate trading; or to seek
higher investment returns or simulate full investment when a futures contract is
priced more attractively or is otherwise considered more advantageous than the
underlying security or index. Each Fund may enter into futures contracts and
options thereon provided that the aggregate deposits required on these contracts
do not exceed 5% of each Fund's total assets. Under normal market conditions,
each Fund may commit a maximum of 25% of its total assets by selling futures,
writing calls or buying puts and will limit its purchases of calls so that the
value of the securities underlying the calls does not exceed 5% of a Fund's
total assets. (See "Investment Securities" in the Statement of Additional
Information.)
 
Futures contracts and options pose certain risks. The primary risks associated
with the use of futures contracts and options include: imperfect correlation
between the change in market value of the securities held by each Fund and the
prices of futures contracts and options, and possible lack of a liquid secondary
market for a futures contract and the resulting inability to close a futures
position prior to its maturity date. The risk of imperfect correlation will be
minimized by investing only in those contracts whose behavior is expected to
resemble that of each Fund's underlying securities. The risk that each Fund will
be unable to close out a futures position will be minimized by entering into
such transactions on a national exchange with an active and liquid secondary
market.
 
The risk of loss in trading futures and options contracts in some strategies can
be substantial, due both to the low margin deposits required and the extremely
high degree of leverage that can be involved in futures and options pricing. As
a result, a relatively small price movement in a futures or options contract may
result in immediate and substantial loss (or gain) to the investor. While
futures contracts and options can be used as leveraged instruments, each Fund
may not use futures contracts or options to leverage its portfolios. When
investing in futures and options contracts, each Fund will segregate cash,
cash-equivalents or liquid, high-quality debt instruments in the amount of the
underlying obligation.
- ------------------------------------------------------------------
THE FUNDS MAY LEND THEIR SECURITIES TO GENERATE ADDITIONAL INCOME.
- ------------------------------------------------------------------
 
To increase their income, the Funds may lend their portfolio securities to
brokers, dealers and other financial institutions that borrow securities. No
more than one-third of each Fund's total assets may be represented by loaned
securities. Each 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 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 Funds may borrow money from banks or other financial institutions as a
temporary measure to satisfy redemption requests or for extraordinary or
emergency purposes and then only in an amount
 
                                        9
<PAGE>   34
 
not to exceed one-third of the value of their total assets (including the amount
borrowed), provided that neither Fund will purchase securities while borrowings
represent more than 5% of its assets.
- --------------------------------------------------------
THE FUNDS MAY ELECT A STRATEGY WHICH INCLUDES PURCHASING
WHEN-ISSUED SECURITIES AND RESTRICTED SECURITIES.
- --------------------------------------------------------
 
Each Fund may purchase and sell securities on a "when-issued" or "firm
commitment" basis. Under these arrangements, the securities' prices and yields
are fixed on the date of the commitment, but payment and delivery are scheduled
for a future time. At the time of settlement, the market value of the security
may be more or less than its purchase or sale price. While the Funds may enter
into these transactions with the intention of actually receiving or delivering
the securities, they may sell these securities before the settlement date or
enter into a new commitment to extend the delivery date further into the future.
Between the time of purchase and settlement, no payment is made by a Fund and no
interest on securities purchased for future delivery is received by that Fund.
 
The Investment Manager may determine that it is in the best interest of a Fund
to purchase or maintain selected illiquid or restricted securities. A Fund will
not purchase illiquid securities if, as a result, more than 10% of its total
assets would be invested in illiquid securities.
 
MANAGEMENT OF THE FUNDS
 
Responsibility for overall management of the Funds rests with the trustees and
officers of the Trust. Professional investment management for the Funds 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, and performs expense
management, accounting and record keeping, and other administrative services
necessary to the operation of the Funds and the Trust. 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 mutual funds in the
SchwabFunds Family(R), a family of 21 mutual funds. As of December 15, 1995,
SchwabFunds had aggregate net assets in excess of $31 billion.
 
Andrea Regan is the Portfolio Manager for the Funds and, as such, has had
primary responsibility for the day-to-day management of each Fund's portfolio
since the commencement of each Fund's operations. Prior to January 1991, Ms.
Regan was Vice President and Manager of Trading for the Bank of California's
investment management division, Merus Capital Management.
 
Stephen B. Ward, the Trust's Senior Vice President and Chief Investment Officer,
also participates in the management of each Fund's portfolio. Prior to April
1991, Mr. Ward was Vice President and Portfolio Manager for Federated Investors.
 
Pursuant to separate agreements, 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 (including associated tax consequences),
responding to daily inquiries, effecting the transfer of each Fund's shares, and
facilitating effective cash
 
                                       10
<PAGE>   35
 
management of shareholders' Schwab account balances. It also furnishes such
office space and equipment, telephone facilities, personnel and informational
literature distribution as is necessary and appropriate in providing shareholder
and transfer agency information and services. Schwab is also each 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 3.3 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 November 30, 1995 was the beneficial owner of
approximately 20.1% of the outstanding shares of that corporation. Mr. Schwab
may be deemed to be a "controlling person" of Schwab and the Investment Manager.
 
Please see the Funds' Annual Report to Shareholders for the fiscal year ended
August 31, 1995 for a discussion by the Investment Manager of each Fund's
performance.
- --------------------------------------------------------------
THROUGH AT LEAST APRIL 30, 1996, THE INVESTMENT MANAGER
AND SCHWAB GUARANTEE THAT THE SHORT/INTERMEDIATE FUND'S
OPERATING EXPENSES WILL NOT EXCEED 0.49% OF THE FUND'S
AVERAGE DAILY NET ASSETS AND THE INVESTMENT MANAGER AND SCHWAB
WILL ABSORB ALL OF THE LONG-TERM FUND'S OPERATING EXPENSES.
- --------------------------------------------------------------
 
FEES AND EXPENSES. Pursuant to its Investment Advisory and Administration
Agreement with the Trust, the Investment Manager receives from each Fund an
annual fee, payable monthly, of 0.41% of each Fund's average daily net assets.
Through at least April 30, 1996, the Investment Manager guarantees that the
Short/Intermediate Fund's management fee will not exceed 0.31% of the Fund's
average daily net assets and that the Investment Manager will waive payment of
all of the Long-Term Fund's management fee. Moreover, at least through April 30,
1996, the Investment Manager and Schwab guarantee that the Short/Intermediate
Fund's total operating expenses will not exceed 0.49% of the Fund's average
daily net assets and that the Investment Manager and Schwab will absorb all of
the Long-Term Fund's operating expenses. The effect of these guarantees is to
maintain or lower each Fund's expenses and thus maintain or increase each Fund's
total return to shareholders.
 
For the transfer agency and shareholder services provided under its Transfer
Agency and Shareholder Service Agreements with the Trust, Schwab receives an
annual fee, payable monthly, of 0.05% and 0.20%, respectively, of each Fund's
average daily net assets. PNC Bank, N.A. is the Funds' Custodian. The Investment
Manager, Schwab and the Custodian may each reduce its fees from time to time in
the future.
 
The Trust pays the expenses of its operations, including the fees and expenses
of independent accountants, legal 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 Trust and its
shares for distribution. In addition, the Trust will incur and pay fees in
connection with

 
                                       11
<PAGE>   36
 
the establishment and maintenance of "sweep" accounts through which the Funds
may make regular investments in other investment companies. The expenses will
generally be allocated among the Trust's investment portfolios on the basis of
relative net assets at the time the expense is incurred. However, expenses
directly attributable to a particular Fund will be charged to that Fund. For the
year ended August 31, 1995, the Short/Intermediate Fund paid investment
management fees of 0.27% and total operating expenses of 0.58% of the Fund's
average daily net assets, and the Long-Term Fund paid no investment management
fees or other operating expenses.
 
PORTFOLIO BROKERAGE. U.S. Government Securities are typically purchased and sold
on the over-the-counter market through dealers acting as principals for their
own accounts. Accordingly, commissions are not charged on these transactions.
Instead, the subject securities are sold on a "net" basis with the participating
dealer(s) earning a spread (the difference between ask and bid price) on each
purchase or sale. The Funds may, however, pay commissions in connection with
their options transactions.
 
When placing orders for each Fund's securities transactions, the Investment
Manager uses its best judgment to obtain best price and execution. The full
range and quality of brokerage services available are considered in making these
determinations. For non-debt security trades in which Schwab is not a principal,
the Investment Manager may use Schwab to execute a Fund's transactions when it
reasonably believes that commissions (or prices) charged and transaction quality
will be at least comparable to those available from other qualified brokers or
dealers.
 
DISTRIBUTIONS AND TAXES
- ---------------------------------------------------------
THE FUNDS DECLARE DAILY DIVIDENDS WHICH ARE PAID MONTHLY.
- ---------------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS. On each day that the net asset value per
share of each Fund is determined (a "Business Day"), each Fund declares a
dividend from net investment income as of the close of trading on the New York
Stock Exchange ("the Exchange") (normally 4:00 p.m. Eastern time) to
shareholders of record at the previous net asset value calculation. Dividends
are normally paid (and, where applicable, reinvested) on the 25th of each month,
if a Business Day, otherwise on the next Business Day, with the exception of the
dividend paid in December, which is paid on the last Business Day of December.
Each Fund intends to distribute substantially all of its net investment income
on an annual basis, and plans to distribute substantially all of its net capital
gains, if any, at least once annually, as determined by the Board of Trustees.
All distributions will be automatically reinvested in additional shares of that
Fund unless the shareholder elects otherwise.
 
TAX INFORMATION. Each Fund is treated as a separate entity for tax purposes, has
elected to be treated as a regulated investment company under Subchapter M of
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 substantially all of its net investment income and net capital gains
to shareholders on an annual basis, and will meet certain other requirements.
Such qualification relieves a Fund of liability for federal income taxes to the
extent its earnings are distributed.
 
Dividends paid by the Funds from net investment income and distributions from
the Fund's net short-term capital gains in excess of any net long-term capital
losses, whether received in cash or
 
                                       12
<PAGE>   37

reinvested, generally will be taxable as ordinary income. Distributions received
from a Fund designated as long-term capital gains (net of capital losses),
whether received in cash or reinvested, will be taxable as long-term capital
gains without regard to the length of time a shareholder has owned shares in a
Fund. Any loss on the sale or exchange of a Fund's shares held for 6 months or
less shall be treated as a long-term capital loss to the extent of any long-term
capital gain distribution received on the shares. If a shareholder is not
subject to tax on his income, generally the shareholder will not be taxed on
amounts distributed by the Fund.
 
Records of dividends and other distributions, purchases and redemptions will be
reflected on shareholders' Schwab account statements. The Funds will notify
shareholders at least annually as to the Federal income tax consequences of all
distributions made each year.
 
Many states grant tax-free status to dividends paid to shareholders of mutual
funds from interest income earned by the mutual fund from direct obligations of
the U.S. Government, subject in some cases to minimum investment requirements.
Investments in repurchase agreements collateralized by U.S. Government
securities do not generally qualify for this purpose. At the end of each
calendar year, the Funds will provide shareholders with the percentage of any
dividends paid which may qualify for such tax-free status. Shareholders should
consult their own tax advisors with respect to the application of state and
local income tax laws to these distributions and on the application of other
state and local intangible property or income tax laws to their shares and to
distributions and redemption proceeds received from the Funds.
 
The foregoing is only a brief summary of the federal income tax considerations
affecting the Funds and their shareholders. Accordingly, a potential investor
should consult his or her tax adviser with specific reference to the
shareholder's own tax situation.
 
SHARE PRICE CALCULATIONS
- -------------------------------------------------
THERE ARE NO SALES CHARGES OR TRANSACTION FEES TO
PURCHASE OR REDEEM SHARES OF A FUND.
- -------------------------------------------------
 
The price of each Fund's shares on any given day is their "net asset value" or
NAV. This amount is computed by dividing the total market value of each Fund's
investments and other assets on that day, less any liabilities, by the number of
Fund shares outstanding. The net asset value per share of each Fund is
determined on each day the Exchange is open for trading at 4:00 p.m., Eastern
time. Each Fund's net asset value will fluctuate and neither Funds' shares are
insured against reduction in net asset value. (See "Share Price Calculation" in
the Statement of Additional Information.) Purchase or redemption orders and
exchange requests will be executed at the NAV next determined after receipt and
verification by Schwab's Mutual Fund Transfer Agency Department.
 
The securities in which the Funds invest will be valued daily based on their
market value. Securities for which market quotations are readily available are
valued at the mean between the most recent bid and asked prices. Price
information on each listed security is taken from the exchange where the
security is primarily traded. Other assets for which no reliable quotations are
readily available (including any restricted securities) are valued at fair value
as determined in good faith by the

 
                                       13
<PAGE>   38
 
Investment Manager pursuant to Board of Trustees' guidelines. Securities may be
valued on the basis of prices provided by pricing services when such prices are
believed to reflect fair market value.
 
HOW THE FUNDS SHOW PERFORMANCE
 
From time to time each Fund may advertise its total return or yield. Performance
figures are based upon historical results and are not intended to indicate
future performance.
 
Each Fund's total return measures its overall change in value over a period,
including share price movements, and assumes all dividends and capital gains
have been reinvested. Average annual total return reflects the hypothetical
annually compounded return mandated by the SEC. Other reported total return
figures may differ in that they may report non-standard periods or represent
aggregate or cumulative return over a stated length of time.
 
Each Fund's yield refers to the income generated by a hypothetical investment in
that Fund over a specific 30-day period. This income is then annualized, which
means that the income generated during the 30-day period is assumed to be
generated every 30 days over an annual period and is shown as a percentage of
the hypothetical investment. (See "Total Return and Yield" in the Statement of
Additional Information.)
 
The Funds' performance may be compared to that of other mutual funds tracked by
mutual fund rating services, various indices of investment performance
(including the Schwab 1000 Index(R)), United States Treasury obligations, bank
certificates of deposit, the Consumer Price Index, and other investments for
which reliable performance data is available. Each Fund's performance may also
be compared to various unmanaged bond indices, including but not limited to the
Salomon Brothers High Grade Index, the Shearson Lehman Government/Corporate Bond
Index, the Merrill Lynch Government/Corporate Bond Master Index, and to Lipper
Analytical Services, Inc. averages and Morningstar, Inc. performance rankings.
 
Additional performance information is available in the Trust's Annual Report to
Shareholders, which is available free of charge by calling 800-2 NO-LOAD, or
from your local Schwab office.
 
TAX-ADVANTAGED RETIREMENT PLANS
- -------------------------------------------------------------
RETIREMENT PLANS OFFER EXCELLENT TAX ADVANTAGES AND THE FUNDS
MAY BE ESPECIALLY SUITABLE INVESTMENTS FOR THEM.
- -------------------------------------------------------------
 
Schwab offers tax-advantaged retirement plans for which the Funds may be a
particularly appropriate investment. 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 IRA accounts with balances of $10,000 or more by September 15, 1996 will
not be charged Schwab's $29 annual IRA account fee for the life of the account.
 
                                       14
<PAGE>   39
 
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 ACCOUNT. 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
 
ABOUT THE TRUST. The Trust was organized as a business trust under the laws of
Massachusetts on October 26, 1990 and may issue an unlimited number of shares of
beneficial interest in one or more investment portfolios or series ("Series").
Currently, shares of seven Series are offered. The Board of Trustees may
authorize the issuance of shares of additional Series if it deems it desirable.
Shares within each Series have equal, noncumulative voting rights and equal
rights as to dividends, assets and liquidation of such Series.
 
The Trust 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 or removing
trustees, changing fundamental policies, or approving an investment advisory
agreement. In addition, a Trustee may be removed by shareholders at a special
meeting called upon written request by shareholders owning at least 10% of the
outstanding shares of the Trust. 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 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, 24 hours a day, 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, a 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 it may be difficult to complete transactions by
telephone 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 on the following pages
to place their orders.
 
                                       15
<PAGE>   40
 
To assist in minimizing administrative costs, share certificates will not be
issued. Records regarding share ownership are maintained by the Transfer Agent.
 
You may purchase shares through an account maintained with Schwab or through any
other entity which has been designated by Schwab. The information on the
following pages regarding the purchase, exchange, and redemption of Fund shares
through a Schwab account relates solely to such transactions through Schwab
accounts and should not be read to apply to such transactions through other
designated entities. For more information, see "Purchase and Redemption of
Shares" in the Statement of Additional Information or contact such designated
entity.
 
HOW TO PURCHASE SHARES
- ----------------------------------------------
YOU MAY PURCHASE SHARES OF THE FUNDS THROUGH A
SCHWAB, IRA, TRUST, OR KEOGH ACCOUNT.
- ----------------------------------------------
 
PURCHASING SHARES THROUGH A SCHWAB ACCOUNT. If you purchase shares of the Funds
through an account maintained with Schwab, payment for shares must be made
directly to Schwab. 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.
 
You may purchase Fund shares using your Schwab account as described below. If
you already have a Schwab account, you 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 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, wire or many other
forms of electronic funds transfer (securities may also be deposited). You may
also buy shares of each Fund using electronic products such as StreetSmart(TM),
The Equalizer(R), and TeleBroker(R). All deposit checks should be made payable
to Charles Schwab & Co., Inc. If you would like to wire funds into your existing
Schwab account, please contact your local Schwab office for instructions.
 
SCHWAB ACCOUNT MINIMUMS AND ASSOCIATED FEES. Schwab requires a $1,000 deposit
and account balance minimum to maintain a Schwab brokerage account ($500 for
custodial accounts). A quarterly fee of $7.50 will be charged on Schwab
brokerage 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 at least
one commissionable trade within the last six months, or if the shareholder's
combined account balances at Schwab total $10,000 or more.
 
Schwab currently imposes no fee for opening a Schwab One(R) account with a
minimum of $5,000 account equity. Schwab One accounts containing less than
$5,000 account equity are subject to a fee

                                       16
<PAGE>   41
 
of $5 per month imposed by Schwab if there have been fewer than two
commissionable trades within the last twelve months.
- ---------------------------------------------------------------
YOUR INITIAL INVESTMENT IN EITHER FUND MAY BE AS LOW AS $1,000.
ADDITIONAL SHARE PURCHASES CAN BE MADE FOR AS LITTLE AS $100.
- ---------------------------------------------------------------
 
MINIMUM FUND INVESTMENT REQUIREMENTS. Your initial investment in a Fund may be
as low as $1,000 ($500 for custodial accounts, Individual Retirement Accounts
and certain other retirement plans). The minimum subsequent investment is $100.
These requirements may be reduced or waived on certain occasions. (See "Purchase
and Redemption of Shares" in the Statement of Additional Information.)
- ---------------------------------------------
SHARES WILL BE PURCHASED AFTER YOU HAVE FUNDS
AVAILABLE IN YOUR ACCOUNT.
- ---------------------------------------------
 
WHEN AND AT WHAT PRICE SHARES WILL BE PURCHASED. You must have funds available
in your Schwab account in order to purchase Fund shares through your Schwab
account. If funds (including those transmitted by wire) are received by Schwab
before the time the Fund's daily net asset value is calculated (normally 4:00
p.m. Eastern time), they will be available for investment on the day of receipt.
If funds arrive after that time, they will be available for investment the next
Business Day.
 
METHODS OF PURCHASING SHARES. Schwab offers you several convenient ways to
purchase shares of the Funds. You may choose the one that works best for you and
Schwab will confirm execution of your purchase order.

  you.
 
AUTOMATIC INVESTMENT:
 
  Once you have satisfied the initial investment requirements, you may authorize
  Schwab to automatically purchase shares at intervals and in amounts
  pre-selected by you on your behalf. (See "Schwab Automatic Investment Plan.")
 
YOU MAY CHOOSE FROM THREE DISTRIBUTION OPTIONS. You may select from the three
distribution options listed below when you first become a shareholder in either
of the Funds. If you already are a shareholder and wish to change your
distribution option, please call your local Schwab office for assistance.
 
1. AUTOMATIC REINVESTMENT: Both income dividends and any capital gains
   distributions will be reinvested in additional shares. This option will be
   selected automatically unless you specify another option. If you are
   purchasing Fund shares through Schwab's Automatic Investment Plan, you must
   choose this distribution option for that Fund.
 
2. CASH DIVIDENDS/REINVESTED CAPITAL GAINS: Income dividends will be paid in
   cash and any capital gain distributions will be reinvested in additional
   shares.
 
3. ALL CASH: Dividends and any capital gain distributions will both be paid in
   cash.
 
Dividends and distributions subject to reinvestment will be invested at the net
asset value next determined after their record date. Cash distributions will be
credited to your Schwab account and will be held there or mailed to you
depending on the standing instructions applicable to your account. For
information on how to wire funds from a Schwab account to a bank, see "Other
Important Information -- Wire Transfers to Your Bank."
 
OTHER PURCHASE INFORMATION. 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 the Funds
are subject to acceptance by the Funds and are not binding until confirmed or
accepted in writing. Any purchase which would result in a single shareholder
owning shares with a value of more than 10% of a Fund's assets or $3 million,
whichever is greater, are subject to prior approval by that Fund. Schwab will
charge a $15 service fee against an investor's Schwab account if
 
                                       18
<PAGE>   43
 
his or her investment check is returned because of insufficient or uncollected
funds or a stop payment order.
 
HOW TO SELL OR EXCHANGE SHARES
 
SALE OF SHARES. 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 on the following pages. Payment for
redeemed shares will be credited directly to your Schwab account no later than
7-days after Schwab's Mutual Fund Transfer Agency Department receives your
redemption instructions in proper form. Redemption proceeds will then be held
there or mailed to you depending on the account standing instructions you have
selected. For information on how to wire funds from your Schwab account to your
bank, see "Other Important Information -- Wire Transfers to Your Bank." 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.
 
Each Fund may suspend redemption rights or postpone payments 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. Each 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 a Fund's net assets,
whichever is less. (See "Purchase and Redemption of Shares" in the Statement of
Additional Information.
 
EXCHANGE OF SHARES. 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 involves the
redemption of Fund shares and the purchase of shares of any SchwabFunds of your
choice. An exchange of shares 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. Each Fund reserves the right on 60 days' written notice to modify,
limit or terminate the exchange privilege.
 
METHODS OF SELLING OR EXCHANGING SHARES.
 
BY PHONE:
 
  To sell shares or to exchange shares between any of the SchwabFunds by
  telephone, please call your local Schwab office during its regular business
  hours or 800-2 NO-LOAD, 24 hours a day. TDD users may contact Schwab at
  800-345-2550, 24 hours a day. To properly process your telephone redemption or
  exchange request, we will need the following information:
 
        - your Schwab account number and your name for verification;
        - the number of shares to be sold or exchanged;
        - the name of the Fund from which you wish to sell or exchange shares;
        - the name of the fund, and class into which shares are to be exchanged,

  account holders in the exact form specified in the account. Once a redemption
  request is mailed, it is irrevocable and may not be modified or canceled.

SCHWAB AUTOMATIC INVESTMENT PLAN
- --------------------------------------------------------
THE FREE SCHWAB AUTOMATIC INVESTMENT PLAN IS A FAST,
CONVENIENT WAY TO MAKE REGULAR INVESTMENTS IN THE FUNDS.
- --------------------------------------------------------
 
Schwab's Automatic Investment Plan ("AIP") allows you to make periodic
investments in non-money market SchwabFunds(R) (and certain other funds
available through Schwab) automatically and conveniently. You can make automatic
investments in any amount, from $100 to $50,000, once you meet a Fund's
investment minimum. Automatic investments are made from your Schwab account, and
you may select from the following methods to make automatic investments: using
the uninvested cash in your Schwab account; using the proceeds of redemption of
shares of the Schwab money fund linked to your Schwab account; or using the
Schwab MoneyLink(R) Transfer Service. As long as you are purchasing a Fund's
shares through AIP, all dividends and distributions paid to you by the Fund must
be reinvested in additional shares of that Fund. For more detailed information
about this service, or to establish your AIP, call your local Schwab office or
800-2 NO-LOAD, 24 hours a day.
 
OTHER IMPORTANT INFORMATION
 
MINIMUM BALANCE AND ACCOUNT REQUIREMENTS. Due to the relatively high cost of
maintaining accounts with smaller holdings, each Fund reserves the right to
redeem a shareholder's shares if, as a result of redemptions, the aggregate
value of a shareholder's holdings in that Fund drops below the Fund's $500
minimum balance requirements ($250 in the case of custodial accounts, IRAs and
other retirement plans). Shareholders will be notified in writing 30 days before
the Fund takes such action to allow them to increase their holdings to at least
the minimum level. Shares of each Fund will be automatically redeemed should the
Schwab account in which they are carried be closed.
 
CONSOLIDATED MAILINGS. In an effort to reduce 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 mailing. If you do not
 
                                       20
<PAGE>   45
 
wish this consolidation to apply to your account(s), please write SchwabFunds 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 on wire transfers. A $15 service fee
will be charged against your Schwab account for each wire sent.

SCHWAB SHORT/INTERMEDIATE TAX-FREE BOND FUND
SCHWAB LONG-TERM TAX-FREE BOND FUND
- --------------------------------------------------------------------------------
PROSPECTUS December 29, 1995
 
TO PLACE ORDERS AND FOR ACCOUNT INFORMATION: Contact your local Charles Schwab &
Co., Inc. ("Schwab") office or call 800-2 NO-LOAD (800-266-5623), 24 hours a
day.
 
THE SCHWAB SHORT/INTERMEDIATE TAX-FREE BOND FUND (the "Short/Intermediate Fund")
and the SCHWAB LONG-TERM TAX-FREE BOND FUND (the "Long-Term Fund," formerly
known as the Schwab National Tax-Free Bond Fund, and, together, with the
Short/Intermediate Fund, the "Funds"), are designed for investors who seek a
high level of current income that is exempt from federal income tax, consistent
with preservation of capital. Both Funds seek to achieve their objective by
investing primarily in debt securities issued by or on behalf of states,
territories, and possessions of the U.S. and the District of Columbia and their
political subdivisions, agencies and instrumentalities, the interest on which is
not subject to regular federal income tax ("Municipal Securities"). Under normal
market conditions, each Fund will invest at least 65% of its assets in Municipal
Securities, including bonds, notes, debentures, and zero coupon securities.
Under normal market conditions, the Short/Intermediate Fund seeks to maintain a
dollar weighted average portfolio maturity of between two and five years and the
Long-Term Fund seeks to maintain a dollar weighted average portfolio maturity of

KEY FEATURES OF THE FUNDS
 
TAX-FREE INCOME. Income from each Fund will generally be exempt from federal
income tax. The Funds may offer higher after-tax yields than some comparable
taxable investments. With the possibility of additional increases in individual
personal income tax rates in coming years, the Funds' tax-exempt returns may
become even more attractive. (See "Investment Objectives and Policies.")
 
EFFECT OF PORTFOLIO MATURITY ON YIELDS. Securities with longer maturities have a
greater risk of fluctuating principal values than shorter-term instruments.
High-quality money market instruments reflect short-term interest rates with
relatively little risk of fluctuation of principal value. The Short/
Intermediate Fund seeks to provide higher yields than money market instruments
by investing in securities to maintain a dollar weighted average portfolio
maturity of between 2 and 5 years. The Long-Term Fund seeks to provide even
higher yields by investing in securities to maintain a dollar weighted average
portfolio maturity of 10 years or longer. (See "Matching the Funds to Your
Investment Needs.")
 
CREDIT SAFETY THROUGH AN INVESTMENT GRADE PORTFOLIO. The Funds will invest only
in municipal securities rated in the four highest rating categories and in
unrated securities deemed to be of equivalent credit quality. For more
information on portfolio securities that may, subsequent to inclusion in a
Fund's portfolio, receive a rating below that required for purchase, see the
section of this Prospectus entitled "Risk Considerations."
 
MONTHLY DIVIDENDS. Dividends on each Fund's shares are declared daily and paid
monthly, unlike individual municipal securities which generally pay interest
semi-annually. Additionally, unlike interest paid on municipal securities,
shareholders can reinvest dividends paid on their Fund's shares. (See
"Distributions and Taxes.")
 
LOW MINIMUM INVESTMENT. Investors can begin their tax-free investment program
with as little as $1,000. Subsequent investments can be made with only $100.
(See "How to Purchase Shares.")
 
PROFESSIONAL MANAGEMENT. Charles Schwab Investment Management, Inc. (the
"Investment Manager"), currently provides investment management services to the
mutual funds in the SchwabFunds Family(R), a family of 21 mutual funds with over
$31 billion in assets as of December 15, 1995. (See "Management of the Funds.")
 
LOW COST INVESTING. The Funds bring a low cost approach to investing with:
 
     - no sales charges or transaction fees;
 
     - no 12b-1 fees or contingent deferred sales charges;
 
     - a portion of the management fees for the Short/Intermediate Fund and the
       Long-Term Fund waived through April 30, 1996 for potentially higher
       returns; and
 
     - a commitment by the Investment Manager and Schwab to absorb operating
       expenses of the Short/Intermediate Fund and the Long-Term Fund in excess
       of 0.49% of each Fund's average daily net assets at least through April
       30, 1996 (see "Management of the Funds").

2 You may be charged a fee if applicable minimum balances are not maintained in
your Schwab brokerage account or Schwab One(R) account. (See "How to Purchase
Shares -- Schwab Account Minimums and Associated Fees.")
 
3 This amount reflects the guarantee by the Investment Manager and Schwab that,
through at least April 30, 1996, the total operating expenses of the
Short/Intermediate Fund will not exceed 0.49% of the Fund's average daily net
assets. Without this guarantee, which was in effect for the fiscal year ended
August 31, 1995, other expenses (as restated) and total operating expenses would
have been 0.48% and 0.89%, respectively, of the Fund's average daily net assets.
 
4 This amount has been restated to reflect the guarantee by the Investment
Manager and Schwab that, through at least April 30, 1996, the total operating
expenses of the Long-Term Fund will not exceed 0.49% of the Fund's average daily
net assets. Without a similar guarantee, which was in effect for the fiscal year
ended August 31, 1995, other expenses and total operating expenses would have
been 0.52% and 0.93%, respectively, of the Fund's average daily net assets.

Note: The Investment Manager and Schwab have reduced a portion of their fees and
absorbed certain expenses in order to limit each 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 Schwab
Short/Intermediate Tax-Free Bond Fund for the periods ended August 31, 1995,
1994 and 1993 would have been 0.89%, .91% and 1.26%*, respectively, and the
ratio of net investment income to average net assets would have been 3.66%,
3.28% and 2.82%*, respectively. With respect to the Schwab Long-Term Tax-Free
Bond Fund the ratio of expenses to average net assets for the periods ended
August 31, 1995, 1994, 1993 and December 31, 1992 would have been 0.93%, .99%,
1.18%* and 1.53%*, respectively, and the ratio of net investment income to

MATCHING THE FUNDS TO YOUR INVESTMENT NEEDS
- ----------------------------------------------------
THE FUNDS MAY BE ESPECIALLY SUITABLE FOR INVESTORS
SEEKING HIGH FEDERAL TAX-FREE INCOME.
- ----------------------------------------------------
 
The Funds may be appropriate for a variety of investment programs. While the
Funds are not a substitute for an investment portfolio tailored to an
individual's investment needs and ability to tolerate risk, they can serve as
components of an investor's long-term program to accumulate assets for
retirement, college tuition or other major goals.
 
Because the Funds invest primarily in Municipal Securities, they may be
especially suitable for investors seeking income that is exempt from federal
income tax. The Funds are not suitable for investors who cannot benefit from the
tax-exempt character of each Fund's dividends, such as IRAs, qualified
retirement plans or tax-exempt entities.
 
INVESTMENT OBJECTIVES AND POLICIES
- ------------------------------------------------------------------
EACH FUND SEEKS A HIGH LEVEL OF CURRENT INCOME THAT IS EXEMPT FROM
FEDERAL INCOME TAX, CONSISTENT WITH PRESERVATION OF CAPITAL.
- ------------------------------------------------------------------
 
Both Funds are investment portfolios of the Trust, a no-load, open-end,
management investment company. The investment objective of each Fund is to seek
a high level of current income that is exempt from federal income tax,
consistent with preservation of capital. Each Fund's investment objective, along
with certain investment restrictions adopted by each Fund (see "Investment
Restrictions" in the Statement of Additional Information), are fundamental, and
cannot be changed without approval by holders of a majority of each Fund's
outstanding voting shares, as defined in the Investment Company Act of 1940 (the
"1940 Act"). While there is no assurance that either Fund will achieve its
investment objective, each will endeavor to do so by following the investment
policies set forth below.
- --------------------------------------------------------
EACH FUND WILL INVEST PRIMARILY IN MUNICIPAL SECURITIES.
- --------------------------------------------------------
 
Under normal market conditions, each Fund will invest at least 80% of its total
assets in debt obligations issued by or on behalf of states, territories and
possessions of the U.S., and the District of Columbia and their political
subdivisions, agencies, and instrumentalities, the interest on which, in the
opinion of bond counsel or other counsel to the issuer, is not subject to
regular federal income tax ("Municipal Securities"). Absent unusual market
conditions, each Fund will invest 65% of its total assets in Municipal
Securities, including bonds, notes, debentures, and zero coupon securities.
Under normal market conditions, the Short/Intermediate Fund seeks to maintain a
dollar weighted average portfolio maturity of between 2 and 5 years. The
Long-Term Fund has no restriction on its portfolio maturity, but its dollar
weighted average portfolio maturity is currently expected to be 10 years or
longer.
 
Each Fund may also purchase shares of other no-load investment companies,
including those managed by the Investment Manager. These purchases will be
subject to the limitations imposed by the 1940 Act, and we will only make these
purchases after obtaining any required regulatory
 
                                        6
<PAGE>   55
 
approvals. Investment in other investment companies may cause you to bear
duplicative fees for certain services. The Investment Manager will charge no
management fees attributable to Fund assets that are invested in other
investment companies. (See "Investment Restrictions" in the Statement of
Additional Information.)
 
Each Fund will invest only in Municipal Securities that at the time of purchase:
(a) are rated within the four highest rating categories for municipal securities
assigned by Moody's Investors Service ("Moody's"), Standard & Poor's Corporation
("S&P"), Fitch Investors Services, Inc. ("Fitch"), or any other nationally
recognized statistical rating organization ("NRSRO"); or (b) are rated within
the two highest rating categories for short-term municipal securities assigned
by any NRSRO; or (c) 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 (such
unrated securities may not exceed 20% of the Fund's net assets). Bonds rated in
the lowest category of investment grade debt may have speculative
characteristics; changes in economic conditions or other circumstances are more
likely to lead to weakened capacity to make principal and interest payments than
is the case with higher grade bonds. For a description of the ratings, see
"Appendix -- Ratings of Investment Securities" in the Statement of Additional
Information.
 
See the section of this Prospectus entitled "Risk Considerations" for more
information on portfolio securities which may, subsequent to inclusion in a
Fund's portfolio, receive a rating below that required for purchase.
 
The frequency of portfolio transactions and each Fund's turnover rate will vary
from year to year depending upon market conditions and purchase and redemption
patterns of each Fund's shareholders. Typically, funds with higher turnover tend
to generate higher capital gains and transaction costs. The Long-Term Fund had
portfolio turnover rates for the years ended August 31, 1995 and 1994, of 70%
and 62%, respectively. The Short/Intermediate Fund had portfolio turnover rates
for the years ended August 31, 1995 and 1994, of 35% and 19%, respectively.
- ----------------------------------
THE FUNDS ARE "NON-DIVERSIFIED."
- ----------------------------------
 
Each Fund is "non-diversified" under the 1940 Act. This means that, with respect
to 50% of each Fund's total assets, the Fund may not invest more than 5% of its
total assets in the securities of any one issuer (other than the U.S.
Government). The balance of each Fund's assets may be invested in as few as two
issuers. Thus, up to 25% of each Fund's total assets may be invested in the
securities of any one issuer. 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.
 
By investing in a portfolio of municipal securities, shareholders in the Funds
enjoy greater diversification than investors holding individual municipal
securities. Additionally, national tax-free funds typically offer greater
diversification and consequently lower credit risk than many single-state
tax-free funds. This diversification also means more investment opportunities
than single-state tax-free funds.
 
                                        7
<PAGE>   56
 
From time to time, as a defensive measure or under abnormal market conditions,
each Fund may invest in taxable "temporary investments" which include:
obligations of the U.S. Government, its agencies or instrumentalities; corporate
debt securities rated within the two highest rating categories established by an
NRSRO, commercial paper rated in the two highest rating categories established
by any NRSRO; certificates of deposit of domestic banks having capital and
surplus in excess of $100 million; and any of the foregoing temporary
investments subject to repurchase agreements. While purchases by a Fund of
certain temporary investments could cause it to generate dividends taxable to
shareholders as ordinary income (see "Distributions and Taxes"), it is each
Fund's primary intention to produce dividends that are not subject to federal
income tax.
 
MUNICIPAL SECURITIES AND INVESTMENT TECHNIQUES
 
Municipal Securities are debt obligations issued by or on behalf of the states,
territories and possessions of the U.S. and the District of Columbia, and their
political subdivisions, agencies and instrumentalities, the interest from which
is exempt from regular federal income tax. These securities are issued to obtain
funds for various public purposes, such as the construction of public
facilities, the payment of general operating expenses or the refunding of
outstanding debts. They may also be issued to finance various private
activities, including lending of funds to public or private institutions for the
construction of housing, educational or medical facilities. Municipal Securities
may also include certain types of industrial development bonds or notes issued
by public authorities to finance privately owned or operated facilities or to
fund short-term cash requirements. Short-term Municipal Securities are generally
issued as interim financing in anticipation of tax collections, revenue receipts
or bond sales to finance various public purposes.
 
The two principal classifications of Municipal Securities are general obligation
and limited obligation or revenue securities. General obligation securities
involve the credit of an issuer possessing taxing power and are payable from the
issuer's general unrestricted revenues. Their payment may depend on an
appropriation by the issuer's legislative body. The characteristics and methods
of enforcement of general obligation securities vary according to the law
applicable to the particular issuer. Limited obligation or revenue securities
are payable only from the revenues derived from a particular facility or class
of facilities, or a specific revenue source, and generally are not payable from
the unrestricted revenues of the issuer. Private activity bonds are in most
cases limited obligation securities, the credit quality of which is directly
related to the corporate user of the facilities. From time to time, the Fund may
invest more than 25% of its total assets in industrial development and private
activity bonds.
 
Each 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 Funds may include variable rate demand
instruments issued by industrial development authorities and other government
entities. In the event variable rate demand instruments that the Funds can
purchase are not rated by any NRSRO, 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 Funds
can purchase. In
 
                                        8
<PAGE>   57
 
some cases, the Funds 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 either Fund, each 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 a 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. Each 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 cause them to
be "illiquid," such securities will be subject to each 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 Funds from financial institutions. The
buyer of a participation interest receives an undivided interest in the
securities underlying the instrument. A Fund will only purchase a participation
interest if: (a) the instrument meets the Fund's previously described quality
standards for Municipal Securities, and (b) 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.
 
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. Neither the Funds nor the Investment
Manager will review or re-evaluate the proceedings relating to the issuance of
Municipal Securities or the bases for such opinions.
 
As a matter of fundamental policy, each 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 its total assets and may pledge up to 10% of its net
assets to secure borrowings. Neither Fund will purchase illiquid securities,
including repurchase agreements maturing in more than seven days, if, as a
result thereof, more than 10% of its net assets valued at the time of the
transaction would be invested in such securities.
 
As part of the Funds' fundamental 80% policy described above, each Fund will not
treat interest income subject to federal alternative minimum tax for individuals
as tax-exempt for purposes of measuring compliance with the policy. To the
extent that the Funds invest in securities, the interest income on which is
treated as a preference item for purpose of the alternative minimum tax,
individual shareholders, depending on their own tax status, may be subject to
federal alternative minimum tax on part of that Fund's distributions derived
from these securities. Corporate shareholders may be subject to the Federal
alternative minimum tax on exempt-interest dividends received from a Fund.

RISK CONSIDERATIONS
 
Investors should note the following considerations before making an investment
in either of the Funds. For more information regarding the risks involved in
investing in municipal securities, see the Funds' Statement of Additional
Information.
 
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, each Fund's policy
of acquiring large positions in the obligations of a relatively small number of
issuers may affect the value of that Fund's portfolio to a greater extent than
that of a fully diversified portfolio.
 
Although the Funds do not presently intend to do so on a regular basis, each
Fund may invest more than 25% of its assets in Municipal Securities, the
interest on which is paid solely from revenues on similar projects. To the
extent that a Fund's assets are concentrated in Municipal Securities payable
from revenues on similar projects, the Funds will be subject to the particular
risks presented by such projects to a greater extent than it would be if its
assets were not so concentrated.
 
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. The Funds 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. Neither Fund will invest more than 25% of its assets in
when-issued or delayed delivery securities or 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, each Fund reserves the right to sell acquired
when-issued or delayed delivery securities before their settlement dates if
deemed advisable.
 
After its purchase by a Fund, an issue of Municipal Securities may cease to be
rated or its rating may be reduced below that required for purchase by the
Funds. Neither event would require the elimination of such an obligation from
the affected Fund's investment portfolio. However, the obligation generally
would be retained only if such retention was determined by the Board of Trustees
of the Trust to be in the best interests of the affected Fund.
 
MANAGEMENT OF THE FUNDS
 
Responsibility for overall management of the Funds rests with the trustees and
officers of the Trust. Professional investment management for the Funds 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, and performs expense
management, accounting and record keeping, and other administrative services
necessary to the operation of the Funds and the Trust. 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 mutual funds in
 
                                       10
<PAGE>   59
 
the SchwabFunds Family(R), a family of 21 mutual funds. As of December 15, 1995,
SchwabFunds had aggregate net assets in excess of $31 billion.
 
Joanne Larkin is the Portfolio Manager for the Funds and, as such, has had
primary responsibility for the day-to-day management of each Fund's portfolio
since the commencement of each Fund's operations. Prior to February 1992, Ms.
Larkin was portfolio manager for the Shearson Lehman California Municipal Bond
Fund and E.F. Hutton's Municipal Cash Reserve Management.
 
Stephen B. Ward, the Trust's Senior Vice President and Chief Investment Officer,
participates in the management of each Fund's portfolio. Prior to April 1991,
Mr. Ward was Vice President and Portfolio Manager for Federated Investors.
 
Pursuant to separate agreements, 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 each Fund's shares, and
facilitating effective cash management of shareholders' Schwab account balances.
It also furnishes such office space and equipment, telephone facilities,
personnel and informational literature distribution as is necessary and
appropriate in providing shareholder and transfer agency information and
services. Schwab is also each 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 3.3 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 November 30, 1995, the beneficial owner of
approximately 20.1% of the outstanding shares of that corporation. Mr. Schwab
may be deemed to be a controlling person of Schwab and the Investment Manager.
 
Please see the Funds' Annual Report to Shareholders for the fiscal year ended
August 31, 1995 for a discussion by the Investment Manager of each Fund's
performance.
- ----------------------------------------------------------------------
THROUGH AT LEAST APRIL 30, 1996, THE INVESTMENT MANAGER AND SCHWAB
GUARANTEE THAT THE TOTAL OPERATING EXPENSES FOR THE SHORT/INTERMEDIATE
FUND AND THE LONG-TERM FUND WILL NOT EXCEED 0.49% OF EACH
FUND'S AVERAGE DAILY NET ASSETS.
- ----------------------------------------------------------------------
 
FEES AND EXPENSES. Pursuant to its Investment Advisory and Administration
Agreement with the Trust, the Investment Manager receives from each Fund an
annual fee, payable monthly, of 0.41% of each Fund's average daily net assets.
Through at least April 30, 1996, the Investment Manager guarantees that the
management fee for the Short/Intermediate Fund and the Long-Term Fund will not
exceed 0.31% of each Fund's average daily net assets. Moreover, at least through
April 30, 1996 the
 
                                       11
<PAGE>   60
 
Investment Manager and Schwab guarantee that the total operating expenses of the
Short/Intermediate Fund and the Long-Term Fund will not exceed 0.49% of each
Fund's average daily net assets. The effect of these reductions and guarantees
is to maintain or lower each Fund's expenses and thus maintain or increase each
Fund's total return to shareholders.
 
For the transfer agency and shareholder services provided under its Transfer
Agency and Shareholder Service Agreements with the Trust, Schwab receives an
annual fee, payable monthly, of 0.05% and 0.20%, respectively, of each Fund's
average daily net assets. PNC Bank, N.A. is the Funds' Custodian. The Investment
Manager, Schwab and the Custodian may each reduce its fees from time to time.
 
The Trust pays the expenses of its operations, including the fees and expenses
of independent accountants, legal 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 Trust and its
shares for distribution. In addition, the Trust will incur and pay fees in
connection with the establishment and maintenance of "sweep" accounts through
which the Funds may make regular investments in other investment companies. The
expenses will generally be allocated among the Trust's investment portfolios on
the basis of relative net assets at the time the expense is incurred. However,
expenses directly attributable to a particular Fund will be charged to that
Fund. For the year ended August 31, 1995, the Short/Intermediate Fund paid
investment management fees of 0.18% and total operating expenses of 0.49% of the
Fund's average daily net assets, and the Long-Term Fund paid investment
management fees of 0.22% and total operating expenses of 0.54% of the Fund's
average daily net assets.
 
DISTRIBUTIONS AND TAXES
- ----------------------------------------------------------
THE FUNDS DECLARE DAILY DIVIDENDS WHICH ARE PAID MONTHLY.
- ----------------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS. On each day that the net asset value per
share of each Fund is determined ("Business Day"), each Fund declares a dividend
from net investment income as of the close of trading on the New York Stock
Exchange (the "Exchange") (normally 4:00 p.m. Eastern time) to shareholders of
record at the previous net asset value calculation. Dividends are normally paid
(and, where applicable, reinvested) on the 25th of each month, if a Business
Day, otherwise on the next Business Day, with the exception of the dividend paid
in December, which is paid on the last Business Day of December. Each Fund
intends to distribute substantially all of its net investment income on an
annual basis, and plans to distribute substantially all of its net capital
gains, if any, at least once annually, as determined by the Board of Trustees.
All distributions will be automatically reinvested in additional shares of a
Fund unless the shareholder elects otherwise.
 
TAX INFORMATION. Each Fund is treated as a separate entity for tax purposes, has
elected to be treated as a regulated investment company under Subchapter M of
the Internal Revenue Code of 1986, as amended (the "Code"), has qualified as
such, and intends to continue to so qualify. In order to so qualify, each Fund
will distribute substantially all of its net exempt-interest income and its
investment company taxable income, and will meet certain other requirements.
Such qualification relieves a Fund of liability for federal income tax to the
extent its earnings are distributed.
 
                                       12
<PAGE>   61
 
FEDERAL INCOME TAXES: Dividends derived from exempt-interest income (known as
"exempt-interest dividends") may be treated by a Fund's shareholders as items of
interest excludable from their federal gross income. 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 such dividends are paid in the form of cash or additional shares. If a
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 take all
exempt-interest dividends into account in determining "adjusted current
earnings" for purposes of calculating their alternative minimum tax.
 
Each Fund may at times purchase Municipal Securities at a discount from the
prices at which they were originally issued, especially during periods of rising
interest rates. For federal income tax purposes, some or all of this market
discount may be included in each Fund's ordinary income and will be taxable to
shareholders as such when it is distributed to them. Taxable distributions which
are reinvested will be taxable as if they had been paid in cash. Shareholders
receiving Social Security benefits or Railroad Retirement Act benefits should
note that exempt-interest dividends will be taken into account in determining
the taxability of such benefits. It is not expected that any portion of the
dividends paid by either Fund will be eligible for the corporate dividends
received deduction. (See "Taxes" in the Statement of Additional Information.)
 
STATE INCOME TAXES: 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 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 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 account statements. The Funds will
notify shareholders at least annually as to the federal income tax consequences
of distributions made each year.
 
The foregoing is only a brief summary of some of the federal income tax
considerations affecting the Funds and their shareholders. Accordingly, a
potential investor should consult his or her tax adviser with specific reference
to his or her own tax situation.
 
SHARE PRICE CALCULATIONS
- --------------------------------------------------
THERE ARE NO SALES CHARGES OR TRANSACTION FEES TO
PURCHASE OR REDEEM SHARES OF A FUND.
- --------------------------------------------------
 
The price of each Fund's shares on any given day is their "net asset value" or
NAV. This amount is computed by dividing the total market value of each Fund's
investments and other assets on that day, less any liabilities, by the number of
shares outstanding. The net asset value per share of each Fund is determined on
each day the Exchange is open for trading at 4:00 p.m., Eastern time. Each
Fund's net
 
                                       13
<PAGE>   62
 
asset value will fluctuate and neither Fund's shares are insured against
reduction in net asset value. (See "Share Price Calculation" in the Statement of
Additional Information.) Purchase or redemption orders and exchange requests
will be executed at the NAV next determined after receipt and verification by
Schwab's Mutual Fund Transfer Agency Department.
 
The securities in which the Funds invest will be valued daily based on their
market value. Securities for which market quotations are readily available are
valued at the mean between the most recent bid and asked prices. Other assets
for which no reliable quotations are readily available (including any restricted
securities) are valued at fair value as determined in good faith by the
Investment Manager pursuant to the Board of Trustees' guidelines. Securities may
be valued on the basis of prices provided by pricing services when such prices
are believed to reflect fair market value.
 
HOW THE FUNDS SHOW PERFORMANCE
- ---------------------------------------------
EACH FUND'S PERFORMANCE MAY BE ADVERTISED ON
A BEFORE OR AFTER-TAX BASIS.
- ---------------------------------------------
 
From time to time each Fund may advertise its total return, yield, effective
yield, taxable equivalent yield, and taxable equivalent effective yield.
Performance figures are based upon historical results and are not intended to
indicate future performance.
 
Each Fund's total return measures its overall change in value over a period,
including share price movements, and assumes all dividends and capital gains
have been reinvested. Average annual total return reflects the hypothetical
annually compounded return mandated by the SEC. Other reported total return
figures may differ in that they may report non-standard periods or represent
aggregate or cumulative return over a stated length of time.
 
Each Fund's yield refers to the income generated by a hypothetical investment in
that Fund over a specific 30-day period. This income is then annualized,which
means that the income generated during the 30-day period is assumed to be
generated every 30 days over an annual period and is shown as a percentage of
the hypothetical investment.
 
Taxable equivalent yield is the yield that a taxable investment must generate in
order to equal (after applicable taxes are deducted) a Fund's yield for an
investor in stated federal income tax brackets. (Normally assumed to be
applicable maximum tax rate.) Taxable equivalent yield is based upon, and will
be higher than, the portion of each Fund's yield that is tax exempt. Each Fund
may also illustrate the hypothetical performance of taxable and tax-free
investments over the long-term to show the effects of compounding tax-free
dividends. 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. (See "Total Return and Yield" in the
Statement of Additional Information.)
 
The Funds' performances may be compared to that of other mutual funds tracked by
mutual fund rating services, various indices of investment performance
(including the Schwab 1000 Index(R)), United States Treasury obligations, bank
certificates of deposit, the Consumer Price Index, and other investments for
which reliable performance data is available. Each Fund's performance may also
be
 
                                       14

compared to various unmanaged bond indices, Lipper Analytical Services Inc.
averages and Morningstar performance rankings.
 
Additional performance Information is available in the Trust's Annual Report to
Shareholders, which is available free of charge by calling 800-2 NO-LOAD, or
from your local Schwab office.
 
GENERAL INFORMATION
 
ABOUT THE TRUST. The Trust was organized as a business trust under the laws of
Massachusetts on October 26, 1990 and may issue an unlimited number of shares of
beneficial interest in one or more investment portfolios or series ("Series").
Currently, shares of seven Series are offered. The Board of Trustees may
authorize the issuance of shares of additional Series if it deems it desirable.
Shares within each Series have equal, noncumulative voting rights and equal
rights as to dividends, assets and liquidation of such Series.
 
The Trust is not required to hold annual 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 or removing trustees, changing
fundamental policies, or approving an investment advisory agreement. In
addition, a Trustee may be removed by shareholders at a special meeting called
upon written request by shareholders owning at least 10% of the outstanding
shares of the Trust. 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 purchase and redemption orders as well as
request exchanges at any one of our over 200 Schwab offices nationwide or by
calling 800-2 NO-LOAD, 24 hours a day, 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, a 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 it may be difficult to complete transactions by
telephone 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 on the next page to
place their orders.

To assist in minimizing administrative costs, share certificates will not be
issued. Records regarding share ownership are maintained by the Transfer Agent.
 
You may purchase shares through an account maintained with Schwab or through any
other entity which has been designated by Schwab. The information on the
following pages regarding the purchase, exchange, and redemption of Fund shares
through a Schwab account relates solely to such transactions through Schwab
accounts and should not be read to apply to such transactions through other
designated entities. For more information, see "Purchase and Redemption of
Shares" in the Statement of Additional Information or contact such designated
entity.
 
HOW TO PURCHASE SHARES
- -----------------------------------------------
YOU MAY PURCHASE SHARES OF THE FUNDS THROUGH A
SCHWAB ACCOUNT.
- -----------------------------------------------
 
If you purchase shares of the Funds through an account maintained with Schwab,
payment for shares must be made directly to Schwab. 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.
 
You may purchase Fund shares using your Schwab account as described below. If
you already have a Schwab account, you 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 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, wire or other forms of
electronic funds transfer (securities may also be deposited). You may also buy
shares of each Fund using electronic products such as StreetSmart(TM), The
Equalizer(R) and TeleBroker(R). All deposit checks should be made payable to
Charles Schwab & Co., Inc. If you would like to wire funds into your existing
Schwab account, please contact your local Schwab office for instructions.
 
SCHWAB ACCOUNT MINIMUMS AND ASSOCIATED FEES. Schwab requires a $1,000 deposit
and account balance minimum to maintain a Schwab brokerage account ($500 for
custodial accounts). A quarterly fee of $7.50 will be charged on Schwab
brokerage 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 at least
one commissionable trade within the last six months, or if the shareholder's
combined account balances at Schwab total $10,000 or more.
 
Schwab currently imposes no fee for opening a Schwab One(R) account with a
minimum of $5,000 account equity. Schwab One accounts containing less than
$5,000 account equity are subject to a fee
 
                                       16
<PAGE>   65
 
of $5 per month imposed by Schwab if there have been fewer than two
commissionable trades within the last twelve months.
- ----------------------------------------------------------------
YOUR INITIAL INVESTMENT IN EITHER FUND MAY BE AS LOW AS $1,000.
ADDITIONAL SHARE PURCHASES CAN BE MADE FOR AS LITTLE AS $100.
- ----------------------------------------------------------------
 
MINIMUM FUND INVESTMENT REQUIREMENTS. Your initial investment in a Fund may be
as low as $1,000 ($500 for custodial accounts). The minimum subsequent
investment is $100. These requirements may be reduced or waived on certain
occasions. (See "Purchase and Redemption of Shares" in the Statement of
Additional Information.)
- ----------------------------------------------
SHARES WILL BE PURCHASED AFTER YOU HAVE FUNDS
AVAILABLE IN YOUR SCHWAB ACCOUNT.
- ----------------------------------------------
 
WHEN AND AT WHAT PRICE SHARES WILL BE PURCHASED. You must have funds available
in your Schwab account in order to purchase Fund shares through your Schwab
account. If funds (including those transmitted by wire) are received by Schwab
before the time the Fund's daily net asset value is calculated (normally 4:00
p.m. Eastern time), they will be available for investment on the day of receipt.
If funds arrive after that time, they will be available for investment the next
Business Day.
 
METHODS OF PURCHASING SHARES. Schwab offers you several convenient ways to
purchase shares of the Funds. You may choose the one that works best for you and
Schwab will confirm execution of your purchase order.

  You may use existing funds in your Schwab account to make initial and
  subsequent share purchases. To place your order, call your local Schwab office

  to cover all or part of your purchase order.

IN PERSON AT A SCHWAB OFFICE:
 
  Visit your local Schwab office where a representative will be happy to assist
  you.
 
AUTOMATIC INVESTMENT:
 
  Once you have satisfied the initial investment requirements, you may authorize
  Schwab to automatically purchase shares at intervals and in amounts
  pre-selected by you on your behalf. (See "Schwab Automatic Investment Plan.")
- ------------------------------------------------
YOU MAY CHOOSE FROM THREE DISTRIBUTION OPTIONS.
- ------------------------------------------------
 
SELECTING A DISTRIBUTION OPTION. You may select from the three distribution
options listed below when you first become a shareholder in either of the Funds.
If you already are a shareholder and wish to change your distribution option,
please call your local Schwab office for assistance.
 
     1. AUTOMATIC REINVESTMENT: Both income dividends and any capital gains
        distributions will be reinvested in additional shares. This option will
        be selected automatically unless you specify another option. If you are
        purchasing Fund shares through Schwab's Automatic Investment Plan, you
        must choose this distribution option for that Fund.
 
     2. CASH DIVIDENDS/REINVESTED CAPITAL GAINS: Income dividends will be paid
        in cash and any capital gain distributions will be reinvested in
        additional shares.
 
     3. ALL CASH: Dividends and any capital gains distributions will both be
        paid in cash.
 
Dividends and distributions subject to reinvestment will be invested at the net
asset value next determined after their record date. Cash distributions will be
credited to your Schwab account and will be held there or mailed to you
depending on the standing instructions applicable to your account. 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. 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 the Funds
are subject to acceptance by the Funds and are not binding until confirmed or
accepted in writing. Any purchase which would result in a single shareholder
owning shares with a value of more than 10% of a Fund's assets or $3 million,
whichever is greater, is subject to prior approval by that Fund. Schwab will
charge a $15 service fee against an investor's Schwab account if his or her
investment check is returned because of insufficient or uncollected funds or a
stop payment order.
 
HOW TO SELL OR EXCHANGE SHARES
 
SALE OF SHARES. 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
 
                                       18
<PAGE>   67
 
on the following pages. Payment for redeemed shares will be credited directly to
your Schwab account no later than 7-days after Schwab's Mutual Fund Transfer
Agency Department receives your redemption instructions in proper form.
Redemption proceeds will then be held there or mailed to you depending on the
account standing instructions you have selected. For information on how to wire
funds from your Schwab account to your bank, see "Other Important
Information -- Wire Transfers to Your Bank."
 
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.
 
Each Fund may suspend redemption rights or postpone payments 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. Each 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 a Fund's net assets,
whichever is less. (See "Purchase and Redemption of Shares" in the Statement of
Additional Information.)
 
EXCHANGE OF SHARES. 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 involves the
redemption of Fund shares and the purchase of shares of any SchwabFunds of your
choice. An exchange of shares 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. Each Fund reserves the right on 60 days' written notice to modify,
limit or terminate the exchange privilege.
 
METHODS OF SELLING OR EXCHANGING SHARES.
 
BY PHONE:
 
  To sell shares or to exchange shares between any of the SchwabFunds by
  telephone, please call your local Schwab office during its regular business
  hours or 800-2 NO-LOAD, 24 hours a day. TDD users may contact Schwab at
  800-345-2550, 24 hours a day. To properly process your telephone redemption or
  exchange request, we will need the following information:
 
        - your Schwab account number and your name for verification;
        - the number of shares to be sold or exchanged;
        - the name of the Fund from which you wish to sell or exchange shares;
        - the name of the fund, and class into which shares are to be exchanged,
          if applicable; and

  Montgomery Street, San Francisco, CA 94104 or your local Schwab office. To
  properly process your mailed redemption
 
                                       19
<PAGE>   68
   or exchange request, we will need the information above and a letter signed

  specified in the account. Once a redemption request is mailed, it is
  irrevocable and may not be modified or canceled.

SCHWAB AUTOMATIC INVESTMENT PLAN
- ----------------------------------------------------------
THE FREE SCHWAB AUTOMATIC INVESTMENT PLAN IS A FAST,
CONVENIENT WAY TO MAKE REGULAR INVESTMENTS IN THE FUNDS.
- ----------------------------------------------------------
 
Schwab's Automatic Investment Plan ("AIP") allows you to make periodic
investments in non-money market SchwabFunds(R) (and certain other funds
available through Schwab) automatically and conveniently. You can make automatic
investments in any amount, from $100 to $50,000, once you meet a Fund's
investment minimum. Automatic investments are made from your Schwab account, and
you may select from the following methods to make automatic investments: using
the uninvested cash in your Schwab account; using the proceeds of redemption of
shares of the Schwab money fund linked to your Schwab account; or using the
Schwab MoneyLink(R) Transfer Service. As long as you are purchasing a Fund's
shares through AIP, all dividends and distributions paid to you by the Fund must
be reinvested in additional shares of that Fund. For more detailed information
about this service, or to establish your AIP, call your local Schwab office or
800-2 NO-LOAD, 24 hours a day.
 
OTHER IMPORTANT INFORMATION
 
MINIMUM BALANCE AND ACCOUNT REQUIREMENTS. Due to the relatively high cost of
maintaining accounts with smaller holdings, each Fund reserves the right to
redeem a shareholder's shares if, as a result of redemptions, the aggregate
value of a shareholder's holdings in that Fund drops below the Fund's $500
minimum balance requirements ($250 in the case of custodial accounts).
Shareholders will be notified in writing 30 days before the Fund takes such
action to allow them to increase their holdings to at least the minimum level.
Shares of each Fund will be automatically redeemed should the Schwab account in
which they are carried be closed.
 
CONSOLIDATED MAILINGS. In an effort to reduce 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 mailing. If you do not wish
this consolidation to apply to your account(s), please write SchwabFunds 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 on wire transfers. A $15 service fee
will be charged against your Schwab account for each wire sent.

SCHWAB CALIFORNIA SHORT/INTERMEDIATE TAX-FREE BOND FUND
SCHWAB CALIFORNIA LONG-TERM TAX-FREE BOND FUND
- --------------------------------------------------------------------------------
PROSPECTUS December 29, 1995
 
TO PLACE ORDERS AND FOR ACCOUNT INFORMATION: Contact your local Charles Schwab &
Co., Inc. ("Schwab") office or call 800-2 NO-LOAD (800-266-5623), 24 hours a
day.
 
THE SCHWAB CALIFORNIA SHORT/INTERMEDIATE TAX-FREE BOND FUND (the
"Short/Intermediate Fund") and the SCHWAB CALIFORNIA LONG-TERM TAX-FREE BOND
FUND (the "Long-Term Fund," formerly known as the Schwab California Tax-Free
Bond Fund; and together with the Short/Intermediate Fund, the "Funds") are
designed for investors who seek a high level of current income that is exempt
from federal income and State of California personal income taxes, consistent
with preservation of capital. Both Funds seek to achieve their objective by
investing primarily in debt securities issued by or on behalf of the State of
California, its political subdivisions, agencies or instrumentalities, the
interest on which, in the opinion of bond counsel, is not subject to regular
federal income and State of California personal income taxes ("California
Municipal Securities"). Under normal market conditions, each Fund will invest at
least 65% of its assets in California Municipal Securities, including bonds,
notes, debentures, and zero coupon securities. Under normal market conditions,
the Short/Intermediate Fund seeks to maintain a dollar weighted average
portfolio maturity of between two and five years, and the Long-Term Fund seeks
to maintain a dollar weighted average portfolio maturity of ten years or longer,
although it may invest in obligations of any maturity. Each Fund is a
non-diversified investment portfolio of Schwab Investments (the "Trust"), a
no-load, open-end, management investment company. Shares of the Funds are
offered to California residents and residents of selected other states.
 
ABOUT THIS PROSPECTUS: THIS PROSPECTUS CONCISELY PRESENTS IMPORTANT INFORMATION
YOU SHOULD KNOW BEFORE INVESTING IN THE FUNDS. PLEASE READ IT CAREFULLY AND
RETAIN IT FOR FUTURE REFERENCE. You can find more detailed information about
each Fund in the Trust's "Statement of Additional Information," dated December
29, 1995 (as amended from time to time). The Statement of Additional Information
has been filed with the Securities and Exchange Commission ("SEC") and is
incorporated by reference into this Prospectus. This Prospectus is also

KEY FEATURES OF THE FUNDS
 
DOUBLE TAX-FREE INCOME. Income from each Fund will generally be exempt from
federal income and State of California personal income taxes. The Funds may
offer higher after-tax yields than some comparable taxable investments. Both
Funds offer tax benefits to California residents, who pay some of the highest
state personal income taxes in the nation. With the possibility of additional
increases in personal income tax rates in coming years, the Funds' tax-exempt
returns may become even more attractive. (See "Investment Objectives and
Policies.")
 
EFFECT OF PORTFOLIO MATURITY ON YIELDS. Securities with longer maturities have a
greater risk of fluctuating principal values than shorter-term investments.
High-quality money market instruments reflect short-term interest rates with
relatively little risk of fluctuation of principal value. The Short/Intermediate
Fund seeks to provide higher yields than money market instruments by investing
in securities with a dollar weighted average portfolio maturity of between 2 and
5 years. The Long-Term Fund seeks to provide even higher yields by investing in
securities with a dollar weighted average portfolio maturity of ten years or
longer. (See "Matching the Funds to Your Investment Needs.")
 
SAFETY THROUGH AN INVESTMENT GRADE PORTFOLIO. The Funds will invest only in
municipal securities rated in the four highest rating categories and in unrated
securities deemed to be of equivalent credit quality. For more information on
portfolio securities that may, subsequent to inclusion in a Fund's portfolio,
receive a rating below that required for purchase, see the section of this
Prospectus entitled "Risk Considerations."
 
MONTHLY DIVIDENDS. Dividends on each Fund's shares are declared daily and paid
monthly, unlike individual municipal securities which generally pay interest
semi-annually. Additionally, unlike interest paid on municipal securities,
shareholders can reinvest dividends paid on their Fund shares. (See
"Distributions and Taxes.")
 
LOW MINIMUM INVESTMENT. Investors can begin their tax-free investment program
with as little as $1,000. Subsequent investments can be made with only $100.
(See "How to Purchase Shares.")
 
PROFESSIONAL MANAGEMENT. Charles Schwab Investment Management, Inc. (the
"Investment Manager"), provides investment management services to the mutual
funds in the SchwabFunds Family(R), a family of 21 mutual funds with over $31
billion in assets as of December 15, 1995. (See "Management of the Funds.")
 
LOW COST INVESTING. Each Fund brings a low cost approach to investing with:
 
     - no sales charges or transaction fees;
     - no 12b-1 fees or contingent deferred sales charges;
     - a portion of the management fees for each Fund waived through April 30,
       1996 for potentially higher returns; and
     - a commitment by the Investment Manager and Schwab to absorb operating
       expenses of the Short/Intermediate Fund and the Long-Term Fund in excess
       of 0.49% of each Fund's average daily net assets at least through April
       30, 1996 (see "Management of the Funds").

daily net assets.

Note: The Investment Manager and Schwab have reduced a portion of their fees and

absorbed, the ratio of expenses to average net assets for the Schwab California
Short/Intermediate Tax-Free Bond Fund for the periods ended August 31, 1995,
1994, and 1993 would have been .84%, .86% and 1.25%*, respectively, and the
ratio of net investment income to average net assets would have been 3.95%,

MATCHING THE FUNDS TO YOUR INVESTMENT NEEDS
- ----------------------------------------------------
THE FUND MAY BE ESPECIALLY SUITABLE FOR INVESTORS
SEEKING HIGH FEDERAL AND CALIFORNIA TAX-FREE INCOME.
- ----------------------------------------------------
 
The Funds may be appropriate for a variety of investment programs. While the
Funds are not a substitute for an investment portfolio tailored to an
individual's investment needs and ability to tolerate risk, they can serve as
components of an investor's long-term program to accumulate assets for
retirement, college tuition or other major goals.
 
Because the Funds invest primarily in California Municipal Securities, they may
be especially suitable for investors seeking income that is exempt from federal
income and State of California personal income taxes. The Funds are not suitable
for investors who cannot benefit from the tax-exempt character of each Fund's
dividends, such as IRAs, qualified retirement plans or tax-exempt entities.
 
INVESTMENT OBJECTIVES AND POLICIES
- ------------------------------------------------------------------
EACH FUND SEEKS A HIGH LEVEL OF CURRENT INCOME THAT IS EXEMPT
FROM FEDERAL INCOME AND STATE OF CALIFORNIA PERSONAL INCOME TAXES,
CONSISTENT WITH PRESERVATION OF CAPITAL.
- ------------------------------------------------------------------
 
Both Funds are separate investment portfolios of the Trust, a no-load, open-end,
management investment company. The investment objective of each Fund is to seek
a high level of current income that is exempt from federal income and State of
California personal income taxes, consistent with preservation of capital. The
investment objectives, along with certain investment restrictions adopted by
each Fund (see "Investment Restrictions" in the Statement of Additional
Information), are fundamental, and cannot be changed without approval by holders
of a majority of each Fund's outstanding voting shares, as defined in the
Investment Company Act of 1940 (the "1940 Act"). While there is no assurance
that either Fund will achieve its investment objective, each will endeavor to do
so by following the investment policies set forth below.
- ---------------------------------------------------------------
EACH FUND INVESTS PRIMARILY IN CALIFORNIA MUNICIPAL SECURITIES.
- ---------------------------------------------------------------
 
Under normal market conditions, each Fund will invest at least 80% of its total
assets in debt obligations issued by or on behalf of the State of California,
its political subdivisions, agencies, and instrumentalities, the interest on
which, in the opinion of bond counsel or other counsel of the issuer, is not
subject to regular federal income and State of California personal income taxes
("California Municipal Securities"), nor to the federal alternative minimum tax
for individuals or the California alternative minimum tax. Absent unusual market
conditions, each Fund will invest at least 65% of its total assets in California
Municipal Securities, including bonds, notes, debentures, and zero coupon
securities. Under normal market conditions, the Short/Intermediate Fund seeks to
maintain a dollar weighted average portfolio maturity of between two and five
years; and the Long-Term Fund seeks to maintain a dollar weighted average
portfolio maturity of 10 years or longer, although it may invest in obligations
of any maturity.
 
                                        6
<PAGE>   79
 
Each Fund may also purchase shares of other no-load investment companies,
including those managed by the Investment Manager. These purchases will be
subject to the limitations imposed by the 1940 Act and each Fund will only make
these purchases after obtaining any required regulatory approvals. Investment in
other investment companies may cause you to bear duplicative fees for certain
services. The Investment Manager will charge no management fees attributable to
Fund assets that are invested in other investment companies. (See "Investment
Restrictions" in the Statement of Additional Information.)
 
Each Fund will invest only in California Municipal Securities that at the time
of purchase: (a) are rated within the four highest rating categories for
municipal securities assigned by Moody's Investors Service ("Moody's"), Standard
& Poor's Corporation ("S&P"), Fitch Investors Services, Inc. ("Fitch"), or any
other nationally recognized statistical rating organization ("NRSRO"); or (b)
are rated within the two highest rating categories for short-term municipal
securities assigned by any NRSRO; or (c) 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 (such unrated securities may not exceed 20% of each Fund's net
assets). Bonds rated in the lowest category of investment grade debt may have
speculative characteristics; changes in economic conditions or other
circumstances are more likely to lead to weakened capacity to make principal and
interest payments than is the case with higher grade bonds. For a description of
the ratings, see "Appendix - Ratings of Investment Securities" in the Statement
of Additional Information.
 
See the section of this Prospectus entitled "Risk Considerations" for more
information on portfolio securities which may, subsequent to inclusion in a
Fund's portfolio, receive a rating below that required for purchase.
 
The frequency of portfolio transactions and each Fund's turnover rate will vary
from year to year depending upon market conditions and purchase and redemption
patterns of each Fund's shareholders. Typically, funds with higher turnover tend
to generate higher capital gains and transaction costs. The Short/Intermediate
Fund had portfolio turnover rates for the years ended August 31, 1995 and 1994
of 62% and 35%, respectively. The Long-Term Fund had portfolio turnover rates
for the years ended August 31, 1995 and 1994 of 46% and 48%, respectively.
- --------------------------------
THE FUNDS ARE "NON-DIVERSIFIED."
- --------------------------------
 
Each Fund is "non-diversified" under the 1940 Act. This means that, with respect
to 50% of each Fund's total assets, the Fund may not invest more than 5% of its
total assets in the securities of any one issuer (other than the U.S.
Government). The balance of each Fund's assets may be invested in as few as two
issuers. Thus, up to 25% of each Fund's total assets may be invested in the
securities of any one issuer. 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.
 
                                        7
<PAGE>   80
 
By investing in a portfolio of municipal securities, shareholders in the Funds
enjoy greater diversification than investors holding individual municipal
securities.
 
From time to time, as a defensive measure or under abnormal market conditions,
each Fund may invest in taxable "temporary investments" which include:
obligations of the U.S. Government, its agencies or instrumentalities, corporate
debt securities rated within the two highest rating categories established by an
NRSRO, commercial paper rated in the two highest rating categories established
by any NRSRO; certificates of deposit of domestic banks having capital and
surplus in excess of $100 million, and any of the foregoing temporary
investments subject to repurchase agreements. While purchases by a Fund of
certain temporary investments could cause it to generate dividends taxable to
shareholders as ordinary income (see "Distributions and Taxes"), it is each
Fund's primary intention to produce dividends that are not subject to federal
income or State of California personal income taxes.
 
CALIFORNIA MUNICIPAL SECURITIES AND INVESTMENT TECHNIQUES
 
California Municipal Securities are debt obligations issued by or on behalf of
the State of California, its political subdivisions, agencies and
instrumentalities, the interest from which, in the opinion of counsel to the
issuer, is exempt from regular federal income and State of California personal
income taxes. These securities are issued to obtain funds for various public
purposes, such as the construction of public facilities, the payment of general
operating expenses or the refunding of outstanding debts. They may also be
issued to finance various private activities, including lending of funds to
public or private institutions for the construction of housing, educational or
medical facilities. California Municipal Securities may also include certain
types of industrial development bonds or notes issued by public authorities to
finance privately owned or operated facilities or to fund short-term cash
requirements. Short-term California Municipal Securities are generally issued as
interim financing in anticipation of tax collections, revenue receipts or bond
sales to finance various public purposes.
 
The two principal classifications of California Municipal Securities are general
obligation and limited obligation or revenue securities. General obligation
securities involve the credit of an issuer possessing taxing power and are
payable from the issuer's general unrestricted revenues. Their payment may
depend on an appropriation by the issuer's legislative body. The characteristics
and methods of enforcement of general obligation securities vary according to
the law applicable to the particular issuer. Limited obligation or revenue
securities are payable only from the revenues derived from a particular facility
or class of facilities, or a specific revenue source, and generally are not
payable from the unrestricted revenues of the issuer. Private activity bonds are
in most cases limited obligation securities, the credit quality of which is
directly related to the corporate user of the facilities. From time to time,
each Fund may invest more than 25% of its total assets in industrial development
and private activity bonds.
 
Each 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.
 
                                        8
<PAGE>   81
 
California Municipal Securities purchased by the Funds may include variable rate
demand instruments issued by industrial development authorities and other
government entities. In the event variable rate demand instruments that the
Funds can purchase are not rated by any NRSRO, 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 Funds can purchase. In some cases, the Funds 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 either Fund, each 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 a 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. Each 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 cause them to be "illiquid," such
securities will be subject to each Fund's restrictions on acquiring and holding
illiquid securities.
 
Participation interests in California Municipal Securities with fixed, floating
or variable rates of interest may be purchased by the Funds from financial
institutions. The buyer of a participation interest receives an undivided
interest in the securities underlying the instrument. A Fund will only purchase
a participation interest if: (a) the instrument meets the Fund's previously
described quality standards for California Municipal Securities, and (b) 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.
 
As a matter of fundamental policy, each 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 its total assets and may pledge up to 10% of its net
assets to secure borrowings. Neither Fund will purchase illiquid securities,
including repurchase agreements maturing in more than seven days, if, as a
result thereof, more than 10% of its net assets valued at the time of the
transaction would be invested in such securities.
 
Opinions relating to the validity of California Municipal Securities and to the
exemption of interest thereon from federal income and State of California
personal income taxes are rendered by bond counsel to the respective issuers at
the time of issuance and are not binding upon the tax authorities or the courts.
Neither the Funds nor the Investment Manager will review or re-evaluate the
proceedings relating to the issuance of California Municipal Securities or the
bases for such opinions.
 
As part of the Funds' fundamental 80% policy described above, each Fund will not
treat interest income specifically subject to federal alternative minimum tax
for individuals as tax-exempt for purposes of measuring compliance with the
policy. To the extent that the Funds invest in securities, the interest income
on which is treated as a preference item for purpose of the alternative minimum
tax, individual shareholders, depending on their own tax status, may be subject
to federal (but not
 
                                        9
<PAGE>   82
 
California) alternative minimum tax on part of that Fund's distributions derived
from these securities. Corporate shareholders may be subject to the federal
alternative minimum tax on exempt-interest dividends received from a Fund.
 
RISK CONSIDERATIONS
 
Investors should note the following considerations before making an investment
in either of the Funds. For more information regarding the risks involved in
investing in municipal securities and California issuers, see the Statement of
Additional Information.
 
Because each Fund invests primarily in California Municipal Securities, the
performance of each Fund may be especially affected by factors pertaining to the
California economy and other factors specifically affecting the ability of
issuers of California Municipal Securities to meet their obligations. As a
result, the value of each Fund's shares may fluctuate more widely than the value
of shares of a portfolio investing in securities relating to a number of
different states. The ability of state, county, or local governments to meet
their obligations will depend primarily on the availability of tax and other
revenues to those governments and on their fiscal conditions generally. The
amounts of tax and other revenues available to governmental issuers of
California Municipal Securities may be affected from time to time by economic,
political, geographic, and demographic conditions. In addition, constitutional
amendments, legislative measures, executive orders, administrative regulations,
and voter initiatives may limit a government's power to raise revenues or
increase taxes and thus could adversely affect the ability to meet financial
obligations. The current State of California general obligation bond ratings are
S&P: A; Moody's: A1; and Fitch: A. Such ratings and any further reductions may
adversely affect the value of such obligations. The availability of federal,
state, and local aid to issuers of California Municipal Securities may also
affect their ability to meet their obligations. Payments of principal and
interest on limited obligation securities will depend on the economic condition
of the facility or specific revenue source from whose revenues the payments will
be made, which in turn could be affected by economic, political, and demographic
conditions in the State of California. Any reduction in the actual or perceived
ability of an issuer of California Municipal Securities to meet its obligations
(including a reduction in the rating of its outstanding securities) would likely
affect adversely the market value and marketability of its obligations and could
affect adversely the values of California obligations as well. "Proposition 13"
and similar California constitutional and statutory amendments and initiatives
have restricted the ability of California taxing entities to increase real
property and other 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 certainty that any California issuer will make full 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.)

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, each Fund's policy
of acquiring large positions in the obligations of a relatively small number of
issuers may affect the value of that Fund's portfolio to a greater extent than
that of a fully diversified portfolio.
 
Although the Funds do not presently intend to do so on a regular basis, each
Fund may invest more than 25% of its assets in California Municipal Securities,
the interest on which is paid solely from revenues on similar projects. To the
extent that a Fund's assets are concentrated in California Municipal Securities
payable from revenues on similar projects, the Funds will be subject to the
particular risks presented by such projects to a greater extent than it would be
if its assets were not so concentrated.
 
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. The Funds 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. Neither Fund will invest more than 25% of its assets in
when-issued or delayed delivery securities or 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, each Fund reserves the right to sell acquired
when-issued or delayed delivery securities before their settlement dates if
deemed advisable.
 
After its purchase by a Fund, an issue of California Municipal Securities may
cease to be rated or its rating may be reduced below that required for purchase
by the Funds. Neither event would require the elimination of such an obligation
from the affected Fund's investment portfolio. However, the obligation generally
would be retained only if such retention was determined by the Board of Trustees
of the Trust to be in the best interests of the affected Fund.
 
MANAGEMENT OF THE FUNDS
 
Responsibility for overall management of the Funds rests with the trustees and
officers of the Trust. Professional investment management for the Funds 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, and performs expense
management, accounting and record keeping, and other administrative services
necessary to the operation of the Funds and the Trust. 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 mutual funds in the
SchwabFunds Family(R), a family of 21 mutual funds. As of December 15, 1995,
SchwabFunds had aggregate net assets in excess of $31 billion.
 
Joanne Larkin is the Portfolio Manager for the Funds and, as such, has had
primary responsibility for the day-to-day management of each Fund's portfolio
since the commencement of each Fund's
 
                                       11
<PAGE>   84
 

operations. Prior to February 1992, Ms. Larkin was portfolio manager for the
Shearson Lehman California Municipal Bond Fund and E.F. Hutton's Municipal Cash
Reserve Management.
 
Stephen B. Ward, the Trust's Senior Vice President and Chief Investment Officer,
participates in the management of each Fund's portfolio. Prior to April 1991,
Mr. Ward was Vice President and Portfolio Manager for Federated Investors.
 
Pursuant to separate agreements, 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 (including associated tax consequences),
responding to daily inquiries, effecting the transfer of each Fund's 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 and appropriate in
providing shareholder and transfer agency information and services. Schwab is
also each 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 3.3 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 November 30, 1995, the beneficial owner of
approximately 20.1% of the outstanding shares of that corporation. Mr. Schwab
may be deemed to be a controlling person of Schwab and the Investment Manager.
 
Please see the Funds' Annual Report to Shareholders for the fiscal year ended
August 31, 1995 for a discussion by the Investment Manager of each Fund's
performance.
- -----------------------------------------------------
THROUGH AT LEAST APRIL 30, 1996, THE INVESTMENT
MANAGER AND SCHWAB GUARANTEE THAT THE TOTAL OPERATING
EXPENSES FOR THE SHORT/INTERMEDIATE FUND AND THE
LONG-TERM FUND WILL NOT EXCEED 0.49% OF EACH FUND'S
AVERAGE DAILY NET ASSETS.
- -----------------------------------------------------
 
FEES AND EXPENSES. Pursuant to its Investment Advisory and Administration
Agreement with the Trust, the Investment Manager receives from each Fund an
annual fee, payable monthly, of 0.41% of each Fund's average daily net assets.
At least through April 30, 1996, the Investment Manager guarantees that the
management fee for the Short/Intermediate Fund and the Long-Term Fund will not
exceed 0.31% of each Fund's average daily net assets. Moreover, at least through
April 30, 1996, the Investment Manager and Schwab guarantee that the total
operating expenses of the Short/Intermediate Fund and the Long-Term Fund will
not exceed 0.49% of each Fund's average daily net assets. The effect of these
reductions and guarantees is to maintain or lower each Fund's expenses and thus
maintain or increase each Fund's total return to shareholders.
 
                                       12
<PAGE>   85
 
For the transfer agency and shareholder services provided under its Transfer
Agency and Shareholder Service Agreements with the Trust, Schwab receives an
annual fee, payable monthly, of 0.05% and 0.20%, respectively, of each Fund's
average daily net assets. PNC Bank, N.A. is the Funds' Custodian. The Investment
Manager, Schwab and the Custodian may each reduce its fees from time to time.
 
The Trust pays the expenses of its operations, including the fees and expenses
of independent accountants, legal 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 Trust and its
shares for distribution. In addition, the Trust will incur and pay fees in
connection with the establishment and maintenance of "sweep" accounts through
which the Fund's may make regular investments in other investment companies. The
expenses will generally be allocated among the Trust's investment portfolios on
the basis of relative net assets at the time the expense is incurred. However,
expenses directly attributable to a particular Fund will be charged to that
Fund. For the year ended August 31, 1995, the Short/Intermediate Fund paid
investment management fees of 0.18% and total operating expenses of 0.50% of the
Fund's average daily net assets, and the Long-Term Fund paid investment
management fees of 0.27% and total operating expenses of 0.58% of the Fund's
average daily net assets.
 
DISTRIBUTIONS AND TAXES
- ---------------------------------------------------------
THE FUNDS DECLARE DAILY DIVIDENDS WHICH ARE PAID MONTHLY.
- ---------------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS: On each day that the net asset value per
share of each Fund is determined ("Business Day"), each Fund declares a dividend
from net investment income as of the close of trading on the New York Stock
Exchange (the "Exchange") (normally 4:00 p.m. Eastern time) to shareholders of
record at the previous net asset value calculation. Dividends are normally paid
(and, where applicable, reinvested) on the 25th of each month, if a Business
Day, otherwise on the next Business Day, with the exception of the dividend paid
in December, which is paid on the last Business Day of December. Each Fund
intends to distribute substantially all of its net investment income on an
annual basis, and plans to distribute substantially all of its net capital
gains, if any, at least once annually, as determined by the Board of Trustees.
All distributions will be automatically reinvested in additional shares of a
Fund unless the shareholder elects otherwise.
 
TAX INFORMATION: Each Fund is treated as a separate entity for tax purposes, has
elected to be treated as a regulated investment company under Subchapter M of
the Internal Revenue Code of 1986, as amended (the "Code"), has qualified as
such, and intends to continue to so qualify. In order to so qualify, each Fund
will distribute substantially all of its net exempt-interest income and its
investment company taxable income, and will meet certain other requirements.
Such qualification relieves a Fund of liability for federal and California
income taxes to the extent its earnings are distributed.
 
FEDERAL INCOME TAXES: Dividends derived from exempt-interest income (known as
"exempt-interest dividends") may be treated by a Fund's shareholders as items of
interest excludable from their federal gross income. 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 such dividends are paid in the form of cash or additional shares.
 
                                       13
<PAGE>   86
 
If a 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 take all
exempt-interest dividends into account in determining "adjusted current
earnings" for purposes of calculating their alternative minimum tax.
 
Each Fund may at times purchase California Municipal Securities at a discount
from the prices at which they were originally issued, especially during periods
of rising interest rates. For federal income tax purposes, some or all of this
market discount may be included in each Fund's ordinary income and will be
taxable to shareholders as such when it is distributed to them.
 
Taxable distributions which are reinvested will be taxable as if they had been
paid in cash. Shareholders receiving Social Security benefits or Railroad
Retirement Act benefits should note that exempt-interest dividends will be taken
into account in determining the taxability of such benefits. It is not expected
that any portion of the dividends paid by either Fund will be eligible for the
corporate dividends received deduction. (See "Taxes" in the Statement of
Additional Information.)
 
CALIFORNIA INCOME TAXES: Dividends paid by the Funds to non-corporate
shareholders that are 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
would be excludable from gross income for California personal income tax
purposes if the obligations were owned by an individual. However, dividends paid
to shareholders that are corporations subject to California franchise or 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 a Fund's dividends are derived from
sources other than interest on 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 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.
 
Interest on "private activity bonds" is not subject to the California
alternative minimum tax. In addition, California does not impose its personal
income tax on Social Security or Railroad Retirement benefits. None of the
interest on indebtedness incurred to purchase or carry shares will be deductible
for California personal income tax purposes.
 
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
 
                                       14
<PAGE>   87
 
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 Funds and their shareholders.
Accordingly, a potential investor should consult his or her tax adviser with
specific reference to his or her own tax situation.
 
SHARE PRICE CALCULATION
- -------------------------------------------------
THERE ARE NO SALES CHARGES OR TRANSACTION FEES TO
PURCHASE OR REDEEM SHARES OF A FUND.
- -------------------------------------------------
 
The price of each Fund's shares on any given day is their "net asset value" or
NAV. This amount is computed by dividing the total market value of each Fund's
investments and other assets on that day, less any liabilities, by the number of
shares outstanding. The net asset value per share of each Fund is determined on
each day the Exchange is open for trading at 4:00 p.m., Eastern time. Each
Fund's net asset value will fluctuate and neither Fund's shares are insured
against reduction in net asset value. (See "Share Price Calculation" in the
Statement of Additional Information.) Purchase or redemption orders and exchange
requests will be executed at the NAV next determined after receipt and
verification by Schwab's Mutual Fund Transfer Agency Department.
 
The securities in which the Funds invest will be valued daily based on their
market value. Securities for which market quotations are readily available are
valued at the mean between the most recent bid and asked prices. Other assets
for which no reliable quotations are readily available (including any restricted
securities) are valued at fair value as determined in good faith by the
Investment Manager pursuant to the Board of Trustees' guidelines. Securities may
be valued on the basis of prices provided by pricing services when such prices
are believed to reflect fair market value.
 
HOW THE FUNDS SHOW PERFORMANCE
- --------------------------------------------
EACH FUND'S PERFORMANCE MAY BE ADVERTISED ON
A BEFORE OR AFTER-TAX BASIS.
- --------------------------------------------
 
From time to time each Fund may advertise its total return, yield, effective
yield, taxable equivalent yield, and taxable equivalent effective yield.
Performance figures are based upon historical results and are not intended to
indicate future performance.
 
Each Fund's total return measures its overall change in value over a period,
including share price movements, and assumes all dividends and capital gains
have been reinvested. Average annual total return reflects the hypothetical
annually compounded return mandated by the SEC. Other reported total return
figures may differ in that they may report non-standard periods or represent
aggregate or cumulative return over a stated length of time.
 
Each Fund's yield refers to the income generated by a hypothetical investment in
that Fund over a specific 30-day period. This income is then annualized, which
means that the income generated during the 30-day period is assumed to be
generated every 30 days over an annual period and is shown as a percentage of
the hypothetical investment.
 
                                       15
<PAGE>   88
 
Taxable equivalent yield is the yield that a taxable investment must generate in
order to equal (after applicable taxes are deducted) a Fund's yield for an
investor in stated federal income and State of California personal 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
Fund's yield that is tax exempt. Each Fund may also illustrate the hypothetical
performance of taxable and double tax-free investments over the long-term to
show the effects of compounding double tax-free dividends. 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. (See "Total Return and Yield" in the Statement of Additional
Information.)
 
A Fund's performance may be compared to that of other mutual funds tracked by
mutual fund rating services, various indices of investment performance
(including the Schwab 1000 Index(R)), United States Treasury obligations, bank
certificates of deposit, the Consumer Price Index, and other investments for
which reliable performance data is available. Each Fund's performance may also
be compared to various unmanaged bond indices, Lipper Analytical Services Inc.
averages and Morningstar performance rankings.
 
Additional performance information is available in the Trust's Annual Report to
Shareholders, which is available free of charge by calling 800-2 NO-LOAD, or
from your local Schwab office.
 
GENERAL INFORMATION
 
ABOUT THE TRUST. The Trust was organized as a business trust under the laws of
Massachusetts on October 26, 1990 and may issue an unlimited number of shares of
beneficial interest in one or more investment portfolios or series ("Series").
Currently, shares of seven Series are offered. The Board of Trustees may
authorize the issuance of shares of additional Series if it deems it desirable.
Shares within each Series have equal, noncumulative voting rights and equal
rights as to dividends, assets and liquidation of such Series.
 
The Trust 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 or removing
trustees, changing fundamental policies, or approving an investment advisory
agreement. In addition, a Trustee may be removed by shareholders at a special
meeting called upon written request by shareholders owning at least 10% of the
outstanding shares of the Trust. 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.

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, a 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 it may be difficult to complete transactions by
telephone 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 on the following pages
to place their orders.
 
To assist in minimizing administrative costs, share certificates will not be
issued. Records regarding share ownership are maintained by the Transfer Agent.
 
You may purchase shares through an account maintained with Schwab or through any
other entity which has been designated by Schwab. The information on the
following pages regarding the purchase, exchange, and redemption of Fund shares
through a Schwab account relates solely to such transactions through Schwab

- ------------------------------------
 
Shares of the Funds are offered to California residents and residents of
selected other states.
 
If you purchase shares of the Funds through an account maintained with Schwab,
payment for shares must be made directly to Schwab. 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

you already have a Schwab account, you 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 your local Schwab office) and mail or
deliver it to your local Schwab office. You may also mail the application to

SCHWAB ACCOUNT MINIMUMS AND ASSOCIATED FEES. Schwab requires a $1,000 deposit
and account balance minimum to maintain a Schwab brokerage account ($500 for
custodial accounts). A quarterly fee of $7.50 will be charged on Schwab
brokerage 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 at least
one commissionable trade within the last six months, or if the shareholder's
combined account balances at Schwab total $10,000 or more.
 
Schwab currently imposes no fee for opening a Schwab One(R) account with a
minimum of $5,000 account equity. Schwab One accounts containing less than
$5,000 account equity are subject to a fee of $5 per month imposed by Schwab if
there have been fewer than two commissionable trades within the last twelve
months.
- ---------------------------------------------------------------
YOUR INITIAL INVESTMENT IN EITHER FUND MAY BE AS LOW AS $1,000.
ADDITIONAL SHARE PURCHASES CAN BE MADE FOR AS LITTLE AS $100.

MINIMUM FUND INVESTMENT REQUIREMENTS. Your initial investment in a Fund may be
as low as $1,000 ($500 for custodial accounts). The minimum subsequent
investment is $100. These requirements may be reduced or waived on certain
occasions. (See "Purchase and Redemption of Shares" in the Statement of
Additional Information.)
- ---------------------------------------------

SELECTING A DISTRIBUTION OPTION. You may select from the three distribution
options listed below when you first become a shareholder in either of the Funds.
If you already are a shareholder and wish to change your distribution option,
please call your local Schwab office for assistance.
 
1. AUTOMATIC REINVESTMENT: Both income dividends and any capital gains
   distributions will be reinvested in additional shares. This option will be
   selected automatically unless you specify another option. If you are
   purchasing Fund shares through Schwab's Automatic Investment Plan, you must
   choose this distribution option for that Fund.
 
2. CASH DIVIDENDS/REINVESTED CAPITAL GAINS: Income dividends will be paid in 
   cash and any capital gain distributions will be reinvested in additional 
   shares.
 
3. ALL CASH: Income dividends and any capital gain distributions will both be
   paid in cash.
 
Dividends and distributions subject to reinvestment will be invested at the net
asset value next determined after their record date. Cash distributions will be
credited to your Schwab account and will be held there or mailed to you
depending on the standing instructions applicable to your account.

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. 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 the Funds
are subject to acceptance by the Funds and are not binding until confirmed or
accepted in writing. Any purchase which would result in a single shareholder
owning shares with a value of more than 10% of a Fund's assets or $3 million,
whichever is greater, is subject to prior approval by the Fund. Schwab will
charge a $15 service fee against an investor's Schwab account if his or her
investment check is returned because of insufficient or uncollected funds or a
stop payment order.
 
HOW TO SELL OR EXCHANGE SHARES
 
SALE OF SHARES. 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 on the following pages. Payment for
redeemed shares will be credited directly to your Schwab account no later than
7-days after Schwab's Mutual Fund Transfer Agency Department receives your
redemption instructions in proper form. Redemption proceeds will then be held
there or mailed to you depending on the account standing instructions you have
selected. For information on how to wire funds from your Schwab account to your
bank, see "Other Important Information -- Wire Transfers to Your Bank."
 
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.
 
Each Fund may suspend redemption rights or postpone payments 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. Each 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 a Fund's net assets,
whichever is less. (See "Purchase and Redemption of Shares" in the Statement of
Additional Information.)
 
EXCHANGE OF SHARES. 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 involves the
redemption of Fund shares and the purchase of shares of any SchwabFunds of your
choice. An exchange of shares 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. Each Fund reserves the right on 60 days' written notice to modify,
limit or terminate the exchange privilege.

METHODS OF SELLING OR EXCHANGING SHARES.
 
BY PHONE:
 
  To sell shares or to exchange shares between any of the SchwabFunds by

SCHWAB AUTOMATIC INVESTMENT PLAN
- --------------------------------------------------------
THE FREE SCHWAB AUTOMATIC INVESTMENT PLAN IS A FAST,
CONVENIENT WAY TO MAKE REGULAR INVESTMENTS IN THE FUNDS.
- --------------------------------------------------------
 
Schwab's Automatic Investment Plan ("AIP") allows you to make periodic
investments in non-money market SchwabFunds(R) (and certain other funds
available through Schwab) automatically and conveniently. You can make automatic
investments in any amount, from $100 to $50,000, once you meet a Fund's
investment minimum. Automatic investments are made from your Schwab account, and
you may select from the following methods to make automatic investments: using
the uninvested cash in your Schwab account; using the proceeds of redemption of
shares of the Schwab money fund linked to your Schwab account; or using the
Schwab MoneyLink(R) Transfer Service. As long as you are purchasing a Fund's
shares through AIP, all dividends and distributions paid to you by the Fund must
be reinvested in additional shares of that Fund. For more detailed information
about this service, or to establish your AIP, call your local Schwab office or
800-2 NO-LOAD, 24 hours a day.

OTHER IMPORTANT INFORMATION
 
MINIMUM BALANCE AND ACCOUNT REQUIREMENTS. Due to the relatively high cost of
maintaining accounts with smaller holdings, each Fund reserves the right to
redeem a shareholder's shares if, as a result of redemptions, the aggregate
value of a shareholder's holdings in that Fund drops below the Fund's $500
minimum balance requirements ($250 in the case of custodial accounts).
Shareholders will be notified in writing 30 days before the Fund takes such
action to allow them to increase their holdings to at least the minimum level.
Shares of each Fund will be automatically redeemed should the Schwab account in
which they are carried be closed.
 
CONSOLIDATED MAILINGS. In an effort to reduce 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 mailing. If you do not wish
this consolidation to apply to your account(s), please write SchwabFunds 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 on wire transfers. A $15 service fee
will be charged against your Schwab account for each wire sent.
