KEY FEATURES
 
MATCHING A FUND TO YOUR INVESTMENT NEEDS. Unlike actively managed funds, each
Fund seeks to track the performance of an index, which attempts to represent a
particular market, or market sector. Because each Fund will invest in a large
number and broad range of bonds, each Fund could provide a diversified bond fund
investment for your asset allocation plan. Each Fund could be an excellent
choice for a variety of investment programs, including the core component of the
bond portion of an investment portfolio tailored to your specific investment
needs.
 
GOALS. Short Bond Fund seeks current income by tracking the performance of the
Lehman Brothers Mutual Fund Short (1-5) Government/Corporate Index. This index
includes U.S. Government and other investment-grade debt securities, such as
corporate and international (dollar-denominated) bonds, with maturities between
1 and 5 years.
 
Total Bond Fund seeks current income by tracking the performance of the Lehman
Brothers Aggregate Bond Index. This is a broad-based index that includes U.S.
Government and other investment-grade debt securities, such as corporate and
international (dollar-denominated) bonds and asset-backed and mortgage-backed
securities with maturities over 1 year.
 
There is no guarantee the Funds will achieve their goals.
 
STRATEGIES. Each Fund intends to achieve its goal by following an indexing
investment strategy.
 
Each Fund intends to operate as a diversified mutual fund.
 
RISKS. While indexing strategies may reduce the risks associated with active
management, they do not ensure against interest rate risks and other risks
typically associated with investing in debt securities, such as income risk,
credit risk, and prepayment/call risks. Read the "Investment Objectives,
Policies and Risks" section for more details.
 
MANAGEMENT. Charles Schwab Investment Management, Inc. (the Investment Manager)
currently provides investment management services to the SchwabFunds(R), a
family of 31 mutual funds with over $60 billion in assets as of February 28,
1998.
 
SHAREHOLDER SERVICE. Charles Schwab & Co., Inc. (Schwab) provides professional
representatives 24 hours a day at 1-800-435-4000 to service your accounts. Read
the "Investing in Shares" section of the prospectus for information on "How to
Buy Shares" and "How to Sell Shares" of the Fund.
 
LOW COST INVESTING. The Investment Manager and Schwab have voluntarily
guaranteed that, through at least October 31, 1998, total operating expenses of
the Short Bond Fund and the Total Bond Fund will not exceed 0.38% and 0.30%,
respectively, of each Fund's daily net assets.

SHAREHOLDER TRANSACTION EXPENSES are charges you may pay when you buy, sell or
exchange shares of the Funds.

Account Maintenance Fees                     NONE**
</TABLE>
 
 * Read the "Investing in Shares" section of the prospectus for information
   concerning wire redemption fees.
 
** Read the "Investing in Shares" section of the prospectus for information
   concerning fees that may be charged if you do not maintain the required
   minimums in a Fund or in your Schwab account.
 
The information on shareholder transaction expenses is for transactions through
a Schwab account. If you are purchasing, selling/exchanging or maintaining
shares of a Fund through an entity other than Schwab, other transaction expenses
may be charged by that entity.

ANNUAL OPERATING EXPENSES are paid by the Funds. These expenses include
management fees paid to the Investment Manager and other fees for services such
as maintaining shareholder records and furnishing shareholder statements and
financial reports. These expenses are factored into the price of a Fund's shares
and into the dividends paid to shareholders. As a shareholder, you are not
charged any of these fees directly.
 
The following figures are based on historical expenses (adjusted to reflect
current fees) and are stated as a percentage of average daily net assets of each
Fund.

PERFORMANCE
 
Typically, mutual funds report performance in terms of total return or yield.
 
TOTAL RETURN is the actual annual return of an investment assuming both the
reinvestment of any income earned and any change in share price. A cumulative
total return is the actual total return of an investment over a stated period of
time, while an average annual total return is a hypothetical rate of return,
which, if achieved annually would have produced the same cumulative total
return. An average annual total return will smooth out the actual year-to-year
fluctuations of an investment's return.
 
YIELD is the actual income earned on an investment over a stated period of time
and annualized (assumed to be generated over a year). For example, a thirty-day
yield measures the income earned on an investment over thirty days, annualizes
it and expresses that income as a percentage of the original investment.
 
An effective yield is calculated similarly, but income earned is assumed to be
reinvested. Because of this compounding effect, effective yields are generally
higher.
 
The Funds did not follow indexing strategies prior to November 1, 1997. As a
result, each Fund's performance should not be expected to track the performance
of its Index prior to that date.
 
Fund strategies, performance and holdings are detailed in financial reports
which are sent to shareholders twice a year. For a free copy of the most recent
financial report, call 1-800-435-4000.

ORGANIZATION & MANAGEMENT
 
EACH FUND IS A DIVERSIFIED MUTUAL FUND. Each Fund is a series of Schwab
Investments (the Trust).
 
THE FUNDS ARE OVERSEEN BY A BOARD OF TRUSTEES. The Board of Trustees meets
regularly to review each Fund's activities, contractual arrangements and
performance. The Board of Trustees is responsible for protecting the interests
of each Fund's shareholders.
 
THE FUNDS MAY HOLD SPECIAL MEETINGS. These meetings may be called for purposes
such as electing Trustees, changing fundamental policies and amending management
contracts. Shareholders are entitled to one vote for each share owned and may
vote by proxy or in person. Proxy materials will be mailed to shareholders prior
to any meetings, and will include a voting card and information explaining the
matters to be voted upon.
 
THE FUNDS ARE MANAGED BY THE INVESTMENT MANAGER. The Investment Manager is
responsible for managing each Fund's day-to-day business affairs, including
picking each Fund's investments; although the Investment Manager is subject to
the overall authority of the Board of Trustees.
 
Stephen B. Ward is the Trust's Senior Vice President and Chief Investment
Officer. He has overall responsibility for the management of the Funds'
portfolios. Mr. Ward joined the Investment Manager as Vice President and
Portfolio Manager in April 1991 and was promoted to his current position in
August 1993. Prior to joining the Investment Manager, Mr. Ward was Vice
President and Portfolio Manager at Federated Investors. He graduated with a
Masters of Business Administration from the Wharton School and a Bachelor of
Arts in Economics from Virginia Tech and has been a Chartered Financial Analyst
since 1985.
 
Kimon Daifotis is the Funds' portfolio manager and is responsible for the
day-to-day management. He joined the Investment Manager as Vice President and
Senior Portfolio Manager in October 1997. Prior to joining the Investment
Manager, Mr. Daifotis was employed by Lehman Brothers as Vice President in fixed
income institutional sales and, prior to that, Senior Portfolio Strategist. He
graduated with a Masters in Business Administration from the University of
Chicago and a Bachelor of Arts in Economics from Claremont McKenna College.
 
For the services performed under its contract with each Fund, the Investment
Manager is entitled to receive a graduated annual fee, payable monthly from each
Fund.
 
For the fiscal year ended August 31, 1997, the Short Bond Fund and the Total
Bond Fund paid the Investment Manager investment management fees of 0.23% and
0.00%, respectively, of each Fund's daily net assets.
 
SCHWAB IS THE FUNDS' SHAREHOLDER SERVICES AND TRANSFER AGENT. Schwab provides
Fund information to shareholders, including share price, reporting shareholder
 
                                        8
<PAGE>   9
 
ownership and account activities and distributing the Funds' prospectuses,
financial reports and other informational literature about the Funds. Schwab
also maintains the office space, equipment and personnel necessary to provide
these services. Schwab also distributes and markets SchwabFunds and services.
 
For the services performed as transfer agent under its contract with each Fund,
Schwab is entitled to receive annual fees from the Funds. The fees are payable
monthly in the amount of 0.05% of each Fund's average daily net assets. For the
services performed as shareholder services agent under its contract with the
Funds, Schwab is entitled to receive annual fees from the Funds. The fees are
payable monthly in the amount of 0.20% of the average daily net assets of the
Funds.
 
THE FUNDS PAY OTHER EXPENSES. These expenses are typically connected with the
Trust's operations, and include legal, audit and custodian fees, as well as the
costs of accounting and registration of the funds. Expenses not directly
attributable to a particular fund will be allocated equitably among the funds in
the Trust.
 
For the fiscal year ended August 31, 1997, the Short Bond Fund and Total Bond
Fund paid total operating expenses in the amounts of 0.49% and 0.20%,
respectively, of each Fund's average daily net assets.
 
The Charles Schwab Corporation is the parent company of the Investment Manager
and Schwab. Charles R. Schwab is the founder, Chairman, Chief Executive Officer
and Director of The Charles Schwab Corporation. As a result of his ownership of
and interests in The Charles Schwab Corporation, Mr. Schwab may be deemed to be
a controlling person of the Investment Manager and Schwab.
 
As of February 28, 1998, the Schwab Asset Director(R)-Balanced Growth Fund owned
approximately 40% of the Total Bond Fund's outstanding shares.

INVESTMENT OBJECTIVES, POLICIES & RISKS
 
INVESTMENT OBJECTIVES
Each Fund's investment objective is to attempt to provide a high level of
current income consistent with preservation of capital by seeking to track the
investment results of a particular bond index through the use of an indexing
strategy.
 
Each Fund's investment objective may be changed only by vote of a majority of
its shareholders. Unless otherwise noted, policies and limitations may be
changed without shareholder approval.
 
INVESTMENT STRATEGIES
Each Fund intends to achieve its objective by following an indexing investment
strategy. Each Fund normally will invest at least 65% of its total assets in the
securities making up its Index (Index Securities).
 
THE INDEXES are the Lehman Brothers Mutual Fund Short (1-5) Government/
Corporate Index (the Short-Term Index) for the Short Bond Fund and the Lehman
Brothers Aggregate Bond Index (the Aggregate Bond Index) for the Total Bond
Fund. The Short-Term Index is a market-weighted index of investment-grade debt
securities with maturities between one and five years representing 1,991
securities as of August 31, 1997. The Aggregate Bond Index is a market-weighted
index of investment-grade debt securities with maturities of greater than one
year representing 6,211 securities as of August 31, 1997. The securities in each
Index also are required to be publicly issued and have a par amount outstanding
of at least $100 million and a fixed interest rate.
 
The table below provides a snap-shot of what each Index looked like on August
31, 1997:

THE INDEXING STRATEGY is a method of investment management that relies on an
index to determine the investments of a fund, rather than the judgment of a
portfolio manager. Of course, the portfolio manager of an index fund still uses
his/her judgment, but not in the traditional sense of investment management. By
following indexing strategies, each Fund seeks to match the investment
performance of its Index.
 
Each Fund will invest in a group of securities, consisting primarily of Index
Securities, which, when taken together, is expected to perform similarly to its
Index. This technique is expected to enable each Fund to track the dividend
income and price movements (total return) of its Index, while minimizing
brokerage, custodial and accounting costs.
 
                                       10
<PAGE>   11
 
Each Fund will seek a correlation between its total return and that of its Index
of 0.9 or better. A perfect correlation of 1.0 is unlikely as the Funds incur
operating expenses unlike the Indexes. The Investment Manager will monitor the
performance of each Fund against its index and will rebalance a Fund
periodically to reduce tracking error. In the event a correlation of 0.9 or
better is not achieved, the Board of Trustees will consider alternative
arrangements.
 
The Funds' transition from an "actively managed" strategy to an "indexing"
strategy is expected to be relatively short. In order to employ the indexing
strategy, the Investment Manager expects that the Funds may initially experience
a higher than normal portfolio turnover rate and certain transition costs (e.g.,
taxable capital gains/losses and transaction costs).
 
THE RISKS for each Fund are basically those risks associated with investing in
debt securities. Generally speaking, there are four types of risk attendant to
investing in debt securities.
 
INTEREST RATE RISK is the potential for fluctuations in bond prices due to
changing interest rates. A Fund's or Index's DWAM is an important factor to
consider when determining interest rate risk. This is because DWAM is a measure
of a Fund's or Index's maturity and maturity generally determines a Fund's or
Index's sensitivity to changes in interest rates.
 
INCOME RISK is the potential for a decline in income due to falling interest
rates.
 
CREDIT RISK is the possibility that a bond issuer will fail to make timely
payments of either interest or principal.
 
PREPAYMENT RISK or CALL RISK is the likelihood that, during periods of falling
interest rates, bonds will be prepaid (or "called") prior to maturity, requiring
the proceeds to be invested at a generally lower interest rate.
 
The amount of each type of risk each Fund will be subject to depends on its
portfolio of investments. Because each Fund intends to track its Index, its risk
profile is generally expected to relate to that of its Index. However, to the
extent that a Fund invests in non-Index Securities or invests in an Index
Security in greater proportion than that of its Index, the Fund may be exposed
to greater risks or different combinations of risks associated with such
investments.
 
Here is how the Investment Manager believes the risk profiles for the Funds will
compare:

PRINCIPAL SECURITIES AND INVESTMENT TECHNIQUES
The different types of Index securities and other securities in which the Funds
may invest are described below:
 
DEBT SECURITIES are obligations, issued by various entities, including
governments and corporations, in order to raise money. They are basically
"IOUs," but are commonly
 
                                       11
<PAGE>   12
 
referred to as bonds. Bonds normally require the issuer to pay a fixed, variable
or floating rate of interest on the amount of money borrowed (the "principal")
until it is paid back (at "maturity"). Upon maturity, the principal must be
repaid.
 
Debt securities experience price changes when interest rates change. As a rule,
when interest rates rise, bond prices decline or "fall," and when interest rates
fall bond prices rise. Typically, longer-maturity bonds react to interest rate
changes more severely than shorter-term bonds (all else being equal) but
generally offer a greater rate of interest. Debt securities also are subject to
the risk that their issuer will fail to meet its obligation to pay interest
and/or principal, and their prices also may be affected by the credit quality of
their issuer. Investment-grade debt securities are medium- and high-quality
securities, although some still possess varying degrees of speculative
characteristics and risk.
 
U.S. GOVERNMENT SECURITIES are debt securities issued by the U.S. Treasury or
issued or guaranteed by the U.S. Government or any of its agencies or
instrumentalities. U.S. Treasury securities are backed by the full faith and
credit of the United States. Not all U.S. Government securities are backed by
the full faith and credit of the United States. Some U.S. Government securities
are supported by a line of credit the issuing entity has with the U.S. Treasury.
Others are supported solely by the credit of the issuing agency or
instrumentality. Of course U.S. Government securities are among the safest
securities, but they are still subject to interest rate risk.
 
MORTGAGE-BACKED SECURITIES represent an interest in an underlying pool of
mortgages. Issuers of these securities include agencies and instrumentalities of
the U.S. Government, such as the Federal Home Loan Mortgage Corporation and the
Federal National Mortgage Association, and private entities, such as banks. The
income paid on mortgage-backed securities depends upon the income received from
the underlying pool of mortgages. Mortgage-backed securities include
collateralized mortgage obligations, mortgage-backed bonds and stripped
mortgage-backed securities. These securities are subject to interest rate risk,
like other debt securities, in addition to prepayment risk.
 
CORPORATE BONDS are debt securities issued by corporations. Although a higher
return is expected from corporate bonds, these securities, while subject to the
same general risks as U.S. Government securities, are subject to greater credit
risk than U.S. Government securities.
 
INTERNATIONAL BONDS involve additional risks because they are issued by foreign
entities, including foreign governments, banks and corporations. Credit and
liquidity supports also may be provided by foreign entities. Foreign entities
may not be subject to the same regulatory and reporting requirements as domestic
entities. In addition, foreign economic, political and legal developments could
have more dramatic affects on the value of a foreign security, including
international bonds, or its payment of interest and repayment of principal.
While
 
                                       12
<PAGE>   13
 
these factors could make international bonds more volatile, the Funds will not
be exposed to any currency risks typically associated with foreign securities
because the Funds only invest in U.S. dollar-denominated international bonds.
 
ASSET-BACKED SECURITIES are securities that are backed by the loans or account
receivables of an entity, such as a bank or credit card company. These
securities are obligations which the issuer intends to repay using the assets
backing them (once collected). Therefore, repayment may depend largely on the
cash-flows generated by the assets backing the securities. Sometimes the credit
support for these securities is limited to the underlying assets, but, in other
cases, may be provided by a third party via a letter of credit or insurance
guarantee. Asset-backed securities are subject to credit and prepayment risks.
 
BOND SUBSTITUTION STRATEGY is a strategy whereby each Fund may, from time to
time, substitute one type of investment-grade bond for another. This means that,
as an example, a Fund may hold more corporate bonds and fewer U.S. Treasury
securities than in its Index in order to increase income. This particular bond
substitution -- a corporate bond substitution -- may increase the Fund's credit
risk, although this may be softened through increased diversification in the
corporate sector of the bond market.
 
CREDIT AND LIQUIDITY SUPPORTS may be employed by issuers to reduce the credit
risk of their securities. Credit supports include letters of credit, insurance
and guarantees. Liquidity supports include puts and demand features. These
arrangements move the credit risk of an investment from the issuer of the
security to the support provider.
 
VARIABLE AND FLOATING RATE SECURITIES pay an interest rate that is adjusted
either periodically or at specific intervals or floats continuously according to
a formula or benchmark. These securities generally are intended to minimize the
fluctuations in value that occur when interest rates rise and fall, however,
some of these securities may be linked to a benchmark in such a way as to cause
greater volatility in the security's value.
 
STRIPPED SECURITIES are securities whose income and principal components are
detached and sold separately from each other. While the risks associated with
stripped securities are similar to other securities, stripped securities are
typically subject to greater changes in value. U.S. Treasury securities that
have been stripped by a Federal Reserve Bank are obligations of the U.S.
Treasury.
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES are securities that are purchased
but are to be delivered to the buyer at a later than customary date, price and
yield. Generally, the purchaser does not pay for these securities or earn
interest on them until they are delivered, but their value could change prior to
delivery.
 
ILLIQUID SECURITIES are securities which are not actively traded or are subject
to legal restrictions and, therefore, may be difficult to sell quickly or
without losses.
 
                                       13
<PAGE>   14
 
Restriction: Each Fund will not purchase illiquid securities if, as a result,
more than 15% of its net assets would be invested in illiquid securities.
 
REPURCHASE AGREEMENTS involve a Fund buying securities (usually U.S. Government
securities) from a seller and simultaneously agreeing to sell them back at an
agreed-upon price (usually higher) and time. There are risks that losses will
result if the seller does not perform as agreed.
 
FUTURES CONTRACTS AND OPTIONS may be entered into by the Funds. A futures
contract requires a Fund to buy or sell a specific dollar amount of a security
at a certain price on a specified future date. There is risk that the securities
will increase or decrease in value prior to that date and cause losses to the
Fund. An option gives a Fund the right to buy or sell a security for an
agreed-upon price during a specified period of time. There is risk of loss to a
Fund if the option is exercised, as well as the loss of the cost of the option
if it is not exercised.
 
The risk of loss as to futures contracts and options can be substantial due to
both the low margin deposits required and the degree of leverage that can be
involved. In order to minimize risks, each Fund will segregate appropriate
assets in the amount of the underlying obligation.
 
SWAP AGREEMENTS are an exchange of one security or asset for another. A swap may
be entered into in order to change the maturity of a Fund's portfolio, to
protect a Fund's value from changes in interest rates or to expose the Fund to a
different security or market. Swap agreements also may be entered into to help a
Fund track its Index. By entering into a swap agreement, a Fund is exposed to
the risk that the counterparty will not fulfill its obligations. In order to
minimize this risk, a Fund will enter into swap agreements only with
counterparties deemed creditworthy by the Investment Manager.
 
The risk of loss in swap agreements can be substantial due to the degree of
leverage that can be involved. In order to help minimize this risk, each Fund
will segregate appropriate assets, as necessary.
 
MONEY MARKET SECURITIES are high-quality, short-term debt securities that may be
issued by entities such as the U.S. Government, corporations and financial
institutions (like banks).
 
SECURITIES OF OTHER INVESTMENT COMPANIES may be purchased by a Fund. These
investments will cause a Fund to bear duplicative fees for certain services.
 
The Funds also employ the policies described below.
 
DIVERSIFICATION involves investing in a wide range of securities and, thereby,
spreading and reducing the risks of investment.
 
Restriction: As a fundamental policy, with respect to 75% of its assets, each
Fund may not purchase the securities of any issuer if, as a result, more than 5%
of its total assets would be invested in the securities of that issuer. This
limitation does not apply to U.S. Government securities.
                                       14
<PAGE>   15
 
BORROWING money is a form of leveraging if a Fund continues to make investments
while borrowings remain outstanding. Borrowing subjects a Fund to interest
costs, which may exceed the interest received on the securities purchased with
the borrowed funds.
 
Restriction: Each Fund may borrow up to 33 1/3% of its total assets for
temporary or emergency purposes; provided that neither Fund will purchase
securities while borrowings represent more than 5% of its total assets.
 
LENDING securities may earn income for a Fund, but could result in losses to the
Fund, and possibly affect share price.

INVESTING IN SHARES
 
BUSINESS DAYS
The Funds are open each day the New York Stock Exchange (NYSE) is open (business
days).
 
NET ASSET VALUE
The price of the shares of each Fund is its NAV. NAV is determined each business
day at the close of the NYSE, generally 4:00 p.m. Eastern time. NAV is
calculated by adding the value of each Fund's assets, subtracting its
liabilities and dividing the result by the number of outstanding shares. Each
Fund's NAV will fluctuate and neither Fund is insured against loss in its NAV.
Each Fund values its portfolio securities based on market quotes if they are
readily available. If market quotes are not readily available, portfolio
securities are assigned fair market values pursuant to guidelines adopted by the
Board of Trustees.

OPENING A SCHWAB ACCOUNT
Schwab was established in 1971 and is one of America's largest discount brokers.
Schwab helps over 4.5 million customers make investment decisions by offering
them low cost brokerage services and providing them with financial products and
information. Visit one of Schwab's 262 branch offices or Schwab's World Wide Web
site (http://www.schwab.com) for information on investment products and
services.
 
Investors may open a Schwab account by simply completing an application,
although institutional investors should contact Schwab to find out if any
additional forms need to be completed.
 
Using a Schwab account, investors have access to investments other than just
mutual funds, such as stocks and bonds. The Securities Investor Protection
Corporation (SIPC) provides account protection of up to $500,000 for the
securities held in a Schwab account, including shares of the Funds. It is
important to remember that SIPC account protection does not protect against
losses due to market or economic conditions.
 
Schwab One(R) accounts are available with a minimum initial investment of
$2,500. A monthly fee of $5.00 will be charged to Schwab One accounts that fall
below a $5,000 minimum balance, unless there have been at least two
commissionable trades within the previous twelve months. Existing Schwab
accounts (no longer available for opening) require a $1,000 minimum account
balance ($500 for custodial accounts). A fee of $7.50 will be charged to Schwab
accounts that fall below this minimum for three consecutive months in a quarter.
The fee, if applicable, will be charged at the end of each quarter, but will be
waived if there has been at least one commissionable trade within the previous
six months, or if the investor's combined Schwab accounts equal $10,000 or more.
The account fees for Schwab and Schwab One accounts will be replaced with a
calendar quarter account fee of $15, effective April 1, 1998. However, this fee
will not be charged if the combined balances of your household's accounts at
Schwab exceed $25,000 at the end of any month in that quarter, you have one
commissionable trade in that or the preceding quarter or you have two or more
commissionable trades during the last four quarters. If you have more than one
account at Schwab, you will be charged only one quarterly fee.
 
Deposits may be made to Schwab accounts by check, wire and other forms of
electronic funds transfer. Securities also may
                                       18
<PAGE>   19
 
be deposited. All checks should be made out to Charles Schwab & Co., Inc. Schwab
will charge a $15 service fee for any checks returned as a result of
insufficient or uncollected funds or a stop order. Monies received by Schwab
before 4:00 p.m. Eastern time will be available for investment in the Fund that
day. Monies received by Schwab after 4:00 p.m. Eastern time will be available
for investment in the Fund the next business day.
 
Contact Schwab for instructions and any applicable fees if you would like to
wire money from your Schwab account.
 
TAX-ADVANTAGED RETIREMENT. Retirement plans offer excellent tax advantage and
the Funds may be especially suitable investments for them. 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, 1998 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 permit 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 1-800-435-4000 for more
information.
 
SCHWAB AUTOMATIC INVESTMENT PLAN. 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 using cash, Sweep Shares of a Schwab Money Fund or the Schwab
MoneyLink(R)Transfer Service. As long as you are purchasing a Fund's shares
through AIP, 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 1-800-435-4000, 24 hours a day.
 
DIVIDENDS & TAXES
Each business day each Fund's net investment income is determined at the close
of the NYSE and declared as a dividend to shareholders of record as of the
previous NAV calculation. Net investment income is calculated by subtracting
each Fund's expenses from the income earned on its investments that day.
Dividends are declared each business day based on the net investment income
determined and are paid on the 25th of each month, if it is a business day,
except in December when dividends are paid on the last business day of the
month. If the 25th is not a business day, dividends are paid on the next
business day.

The following is only a brief summary of some of the federal and state income
tax consequences that may affect each Fund and its shareholders. Unless your
investment in a Fund is through a retirement account, you should consider the
tax implications of investing, and consult with your own tax adviser.
 
Each Fund will distribute its net investment income and capital gains, if any,
to shareholders each year. All distributions received by shareholders are
subject to federal income tax, and may be subject to state and/or local taxes.
Note that most states grant tax-exempt status to distributions paid to
shareholders from interest income derived from U.S. Government securities.
Distributions are taxable when paid, whether they are received in cash or
reinvested, although distributions declared in December, but paid in January,
are taxable as if they were paid on December 31.
 
Shareholders receive a record of all distributions by a Fund, as well as
purchases and sales they have made, via their monthly Schwab account statement.
Each year, a Fund notifies shareholders of all distributions made by each Fund
that year, including the percentage of dividends paid which may qualify for
tax-exempt status.
 
GENERAL INFORMATION
As long as either Fund or Schwab follows reasonable procedures to confirm that
your telephone order is genuine, they will not be liable for any losses an
investor may experience due to unauthorized or fraudulent instructions.
 
These procedures may include:
- -  requiring a form of personal identification before acting upon any telephone
   order;
- -  providing written confirmation of telephone orders; and
- -  tape recording all telephone orders.
 
It may be difficult to place orders by telephone during periods of drastic
economic or market changes because Schwab's phone lines may become very busy
with calls from other investors. Consider other methods for placing an order,
such as writing to the Funds.
 
Share certificates will not be issued in order to avoid additional
administrative costs, however, share ownership records are maintained by Schwab.
Twice a year, financial reports will be mailed to shareholders describing each
Fund's performance and investment holdings. In order to reduce these mailing
costs, each household will receive one consolidated mailing. If you do not want
to receive consolidated mailings, you may write to your Fund and request that
your mailings not be consolidated.

                           U.S. GOVERNMENT SECURITIES

         Direct obligations of the U.S. Government are supported by the full
faith and credit of the U.S. Treasury. While obligations of certain U.S.
Government agencies and instrumentalities are similarly backed, those of others,
such as the Federal National Mortgage Association and the Student Loan Marketing
Association, are only supported by the right of the issuer to borrow from the
U.S. Treasury, the discretionary authority of the U.S. Government to purchase
the agency's obligations or the credit of the issuing agency or instrumentality.
There can be no assurance that the U.S. Government would provide financial
support to U.S. Government sponsored agencies or instrumentalities if it were
not obligated to do so by law. A Fund will invest in U.S. Government securities
not backed by the full faith and credit of the U.S. Treasury only when Charles
Schwab Investment Management, Inc. (the "Investment Manager") is satisfied that
the credit risk with respect to their issuer is minimal.

                     GOVERNMENT "MORTGAGE BACKED" SECURITIES

         Government "mortgage-backed" (or government guaranteed
mortgage-related) securities are among the U.S. Government securities in which
the Funds may invest. Mortgages backing the securities purchased by certain
Funds include, among others, conventional 30-year fixed rate mortgages,
graduated payment mortgages, 15-year mortgages and adjustable rate mortgages.
All of these mortgages can be used to create pass-through securities. A
pass-through security is formed when mortgages are pooled together and undivided
interests in the pool or pools are sold. The cash flow from the mortgages is
passed through to the holders of the securities in the form of periodic payments
of interest, principal and prepayments (net of a service fee). Prepayments occur
when the holder of an individual mortgage prepays the remaining principal before
the mortgage's scheduled maturity date. As a result of the pass-through of
prepayments of principal on the underlying securities, mortgage-backed
securities are often subject to more rapid prepayment of principal than their
stated maturity indicates. Because the prepayment characteristics of the
underlying mortgages vary, it is not possible to predict accurately the realized
yield or average life of a particular issue of pass-through certificates.
Prepayment rates are important because of their effect on the yield and price of
the securities. Accelerated prepayments adversely impact yields for
pass-throughs purchased at a premium (i.e., a price in excess of principal
amount) and may involve additional risk of loss of principal because the premium
may not be fully amortized at the time the obligation is repaid. The opposite is
true for pass-throughs purchased at a discount. Certain Funds may purchase
mortgage-related securities at a premium or at a discount. Principal and
interest payments on the mortgage-related securities are guaranteed by the
government to the extent described below. Such guarantees do not extend to the
value or yield of the mortgage-related securities themselves or of a Fund's
shares.

         GNMA Certificates. Certificates of the Government National Mortgage
Association ("GNMA") are mortgage securities which evidence an undivided
interest in a pool or pools of mortgages. GNMA Certificates that the Funds may
purchase are the "modified pass-through" type, which entitle the holder to
receive timely payment of all interest and principal payments due on the
mortgage pool, net of fees paid to the "issuer" and GNMA, regardless of whether
or not the mortgagor actually makes the payment.


                                       2
<PAGE>   27
         The National Housing Act authorized GNMA to guarantee the timely
payment of principal and interest on securities backed by a pool of mortgages
insured by the Federal Housing Administration ("FHA") or guaranteed by the
Veterans Administration ("VA"). The GNMA guarantee is backed by the full faith
and credit of the U.S. Government. The GNMA is also empowered to borrow without
limitation from the U.S. Treasury if necessary to make any payments required
under its guarantee.

         The average life of a GNMA Certificate is likely to be substantially
shorter than the original maturity of the mortgages underlying the securities.
Prepayments of principal by mortgagors and mortgage foreclosures will usually
result in the return of the greater part of principal investment long before the
maturity of the mortgages in the pool. Foreclosures impose no risk to principal
investment because of the GNMA guarantee, except to the extent that a Fund has
purchased the certificates above par in the secondary market.

         FHLMC Securities. The Federal Home Loan Mortgage Corporation ("FHLMC")
was created in 1970 to promote development of a nationwide secondary market in
conventional residential mortgages. The FHLMC issues two types of mortgage
pass-through securities ("FHLMC Certificates"): mortgage participation
certificates ("PCs") and guaranteed mortgage certificates ("GMCs"). PCs resemble
GNMA Certificates in that each PC represents a pro rata share of all interest
and principal payments made and owed on the underlying pool. The FHLMC
guarantees timely monthly payment of interest on PCs and the ultimate payment of
principal.

         GMCs also represent a pro rata interest in a pool of mortgages.
However, these instruments pay interest semi-annually and return principal once
a year in guaranteed minimum payments. The expected average life of these
securities is approximately 10 years. The FHLMC guarantee is not backed by the
full faith and credit of the U.S. Government.

         FNMA Securities. The Federal National Mortgage Association ("FNMA") was
established in 1938 to create a secondary market in mortgages the FHA insures.
FNMA issues guaranteed mortgage pass-through certificates ("FNMA Certificates").
FNMA Certificates resemble GNMA Certificates in that each FNMA Certificate
represents a pro rata share of all interest and principal payments made and owed
on the underlying pool. FNMA guarantees timely payment of interest and principal
on FNMA Certificates. The FNMA guarantee is not backed by the full faith and
credit of the U.S. Government.

                          OTHER ASSET-BACKED SECURITIES

         Certain Funds may invest a portion of its assets in debt obligations
known as "Asset-Backed Securities" that are rated in one of the four highest
rating categories by a nationally recognized statistical rating organization
(e.g., Standard & Poor's Corporation or Moody's Investors Service, Inc.) or, if
not so rated, deemed to be of equivalent quality by the Investment Manager
pursuant to guidelines adopted by the Board of Trustees. The credit quality of
most Asset-Backed Securities depends primarily on the credit quality of the
assets underlying such securities, how well the entity issuing the security is
insulated from the credit risk of the originator (or any other affiliated
entities) and the amount and quality of any credit support provided to the
securities. The rate of principal payments on Asset-Backed Securities generally
depends on the rate of principal payments received on the underlying assets,
which in turn may be affected by a variety of economic and other factors. As a
result, the yield on any Asset-Backed Security is difficult to predict with
precision, and actual yield to maturity may be more or less than the anticipated
yield to maturity.


                                       3
<PAGE>   28
Asset-Backed Securities may be classified as "Pass-Through Certificates" or
"Collateralized Obligations."

         "Pass-Through Certificates" are Asset-Backed Securities that represent
undivided fractional ownership interests in the underlying pool of assets.
Pass-Through Certificates usually provide for payments of principal and interest
received to be passed through to their holders, usually after deduction for
certain costs and expenses incurred in administering the pool. Because
Pass-Through Certificates represent ownership interests in the underlying
assets, the holders thereof bear directly the risk of any defaults by the
obligors on the underlying assets not covered by any credit support.

         Asset-Backed Securities issued in the form of debt instruments, also
known as Collateralized Obligations, are generally issued as the debt of a
special purpose entity organized solely for the purpose of owning such assets
and issuing such debt. The assets collateralizing such Asset-Backed Securities
are pledged to a trustee or custodian for the benefit of the holders thereof.
Such issuers generally hold no assets other than those underlying the
Asset-Backed Securities and any credit support provided. As a result, although
payments on such Asset-Backed Securities are obligations of the issuers, in the
event of default on the underlying assets not covered by any credit support, the
issuing entities are unlikely to have sufficient assets to satisfy their
obligations on the related Asset-Backed Securities.

         Repayment of these securities is intended to be obtained from an
identified pool of assets, typically receivables related to a particular
industry, such as asset-backed securities related to credit card receivables,
automobile receivables, trade receivables or diversified financial assets. Based
on the primary characteristics of the various types of asset-backed securities,
for purposes of each Fund's concentration policy, each of the Funds has selected
the following asset-backed securities industries: Credit card receivables,
automobile receivables, trade receivables and diversified assets, and each Fund
will limit its investments in each such industry to less than 25% of its total
assets.

                        METHODS OF ALLOCATING CASH FLOWS

         While many Asset-Backed Securities are issued with only one class of
security, many others are issued in more than one class, each with different
payment terms. Multiple class Asset-Backed Securities are issued for two main
reasons. First, multiple classes may be used as a method of providing credit
support. This is typically accomplished by creating one or more classes with a
right to payments on the Asset-Backed Security that is subordinate to that of
the remaining class or classes. Second, multiple classes may permit the issuance
of securities with payment terms, interest rates or other characteristics that
differ both from those of each other and from those of the underlying assets.
Examples include so-called "multi-tranche CMOs" (collateralized mortgage
obligations) with serial maturities such that all principal payments received on
the mortgages underlying the securities are first paid to the class with the
earliest stated maturity, and then sequentially to the class with the next
stated maturity, "Strips" (Asset-Backed Securities that entitle the holder to
disproportionate interests with respect to the allocation of interest and
principal of the assets backing the security) and securities with a class or
classes having characteristics that mimic the characteristics of
non-Asset-Backed Securities, such as floating interest rates (i.e., interest
rates that adjust as a specified benchmark changes) or scheduled amortization of
principal.

<PAGE>   29
                             TYPES OF CREDIT SUPPORT

         Asset-Backed Securities are often backed by a pool of assets
representing the obligations of a number of different parties. To lessen the
effect of failures by obligors on these underlying assets to make payments, such
securities may contain elements of credit support. Such credit support falls
into two classes: liquidity protection and protection against ultimate default
on the underlying assets. Liquidity protection refers to the provision of
advances, generally by the entity administering the pool of assets, to ensure
that scheduled payments on the underlying pool are made timely. Protection
against ultimate default ensures payment on at least a portion of the assets in
the pool. Such protection may be provided through guarantees, insurance policies
or letters of credit obtained from third parties, through various means of
structuring the transaction, or through a combination of such approaches.
Examples of Asset-Backed Securities with credit support that arises out of the
structure of the transaction include "senior-subordinated securities" (multiple
class Asset-Backed Securities with certain classes subordinate to other classes
as to the payment of principal thereon, so that defaults on the underlying
assets are borne first by the holders of the subordinated class) and
Asset-Backed Securities that have "reserve funds" (cash or investments,
sometimes funded from a portion of the initial payments on the underlying
assets, are held in reserve against future losses) or that have been
"overcollateralized" (the scheduled payments on, or the principal amount of, the
underlying assets substantially exceed that required to make payment on the
Asset-Backed Securities and pay any servicing or other fees). The degree of
credit support provided on each issue is generally based on historical
information respecting the level of credit risk associated with such payments.
Delinquency or loss in excess of that anticipated could adversely affect the
return on an investment in an Asset-Backed Security.

                        CREDIT CARD RECEIVABLE SECURITIES

         Certain Funds may invest in Asset-Backed Securities backed by
receivables from revolving credit card agreements ("Credit Card Receivable
Securities"). Most of the Credit Card Receivable Securities issued publicly to
date have been Pass-Through Certificates. In order to lengthen the maturity of
Credit Card Receivable Securities, most such securities provide for a fixed
period during which only interest payments on the underlying accounts are passed
through to the security holder and principal payments received on such accounts
are used to fund the transfer of additional credit card charges made on an
account to the pool of assets supporting the related Credit Card Receivable
Securities. The initial fixed period may usually be shortened upon the
occurrence of specified events that signal a potential deterioration in the
quality of the assets backing the security, such as the imposition of a cap on
interest rates. The ability of the issuer to extend the life of an issue of
Credit Card Receivable Securities thus depends upon the continued generation of
additional principal amounts in the underlying accounts during the initial
period and the non-occurrence of specified events. Competitive and general
economic factors could adversely affect the rate at which new receivables are
created in an account and conveyed to an issuer, shortening the expected
weighted average life of the related Credit Card Receivable Security, and
reducing its yield. An acceleration in cardholders' payment rates or any other
event that shortens the period during which additional credit card charges on an
account may be transferred to the pool of assets supporting the related Credit
Card Receivable Security could have a similar effect on the weighted average
life and yield.


                                       5
<PAGE>   30
         Credit card holders are entitled to the protection of a number of state
and federal consumer credit laws, many of which give such holders the right to
set off certain amounts against balances owed on the credit card, thereby
reducing amounts paid on accounts. In addition, unlike most other Asset-Backed
Securities, accounts are unsecured obligations of the cardholder.

  CORPORATE BONDS AND CALL RIGHTS ATTRIBUTABLE TO CORPORATE BOND SINKING FUNDS

         The Funds may invest in corporate bonds, which are debt instruments
issued by corporations or other similar non-governmental entities. All of the
Index Securities that the Funds invest in will be "investment grade securities,"
which are securities rated in the four highest rating categories of a nationally
recognized statistical ratings organization (NRSROs). Debt obligations rated in
the lowest of the top four ratings (i.e., "Baa" by Moody's) are considered to
have some speculative characteristics and are more sensitive to economic change
than higher rated securities. Corporate bonds rated below investment grade, high
yield bonds, are issued by companies without long track records of sales and
earnings, or by those of questionable credit strength, and are more speculative
and volatile (though typically higher yielding) than investment grade bonds. The
Funds do not intend to invest in junk bonds, however, if an investment grade
bond is downgraded to below investment grade, a Fund is not obligated to sell
the security until such time as the Investment Manager determines that it is
appropriate to dispose of the security. See the Appendix for a full description
of the various ratings assigned to these obligations by various NRSROs.
Corporate bonds are subject to certain risks to which U.S. Government securities
are exposed and generally have a higher credit risk and higher interest rate.
Corporate bonds are backed only by the obligation and ability of the corporation
to pay principal and interest whereas U.S. Government securities are backed
either by the U.S. Treasury's obligation or the issuing agency or
instrumentality. The Investment Manager will invest in a corporate bond issue
when it determines that the return or other features of the bond justify
exposing a Fund to the risks associated with that bond.

         International (Dollar-Denominated) Bonds. The Funds may invest in
certain obligations or securities of foreign issuers, including Eurodollar
Bonds, which are U.S. dollar denominated bonds issued by foreign issuers payable
in Eurodollars (U.S. dollars held in banks located outside the United States,
primarily Europe), Yankee Bonds, which are U.S. dollar-denominated bonds issued
in the U.S. by foreign banks and corporations, and EuroBonds, which are bonds
denominated in U.S. dollars and usually issued by large underwriting groups
composed of banks and issuing houses from many countries. Investments in
securities issued by foreign issuers, including American Depository Receipts and
securities purchased on foreign securities exchanges, may subject a Fund to
additional investment risks, such as adverse political and economic
developments, possible seizure, nationalization or expropriation of foreign
investments, less stringent disclosure requirements, non-U.S. withholding taxes
and the adoption of other foreign governmental restrictions.

         Additional risks include less publicly available information, the risk
that companies may not be subject to the accounting, auditing and financial
reporting standards and requirements of U.S. companies, the risk that foreign
securities markets may have less volume and therefore may be less liquid and
their prices more volatile than U.S. securities, and the risk that custodian and
transaction costs may be higher. Foreign issuers of securities or obligations
are often subject to accounting treatment and engage in business practices
different from those respecting domestic issuers of similar securities or
obligations. Foreign branches of U.S. banks and foreign banks


                                       6
<PAGE>   31
may be subject to less stringent reserve requirements than those applicable to
domestic branches of U.S. banks.

         Bond Substitution Strategy. This is a strategy whereby each Fund may,
from time to time, substitute one type of investment-grade bond for another.
This means that, as an example, a Fund may hold more corporate bonds and fewer
U.S. Treasury securities than in its Index in order to increase income. This
particular bond substitution - a corporate bond substitution -- may increase the
Fund's credit risk, although this may be softened through increased
diversification in the corporate sector of the bond market.

         Each Fund will restrict its corporate bond substitutions to issues with
less than 4 years remaining to maturity, and in the aggregate to no more than
15% of its net assets.

         Sinking Fund Risks. Bonds typically carry a contract that describes the
rights of a bondholder until the bond's maturity. Within the contract an issuer
may include a provision describing the issuer's establishment of a sinking fund.
A sinking fund is the issuer's commitment to set aside a certain amount of money
in a sinking fund to cover timely repayment of a bondholder's principal raised
by a bond issuance. By creating a sinking fund, the issuer is able to spread
repayment of principal to numerous bondholders while reducing reliance on its
then current cash flows. A sinking fund also may allow the issuer to annually
repurchase certain of its outstanding bonds from the open market or repurchase
certain of its bonds at a call price named in a sinking fund provision. This
call provision will allow bonds to be prepaid or called prior to a bond's
maturity. The likelihood of such to occur is during periods of falling interest
rates.

                CERTIFICATES OF DEPOSIT AND BANKER'S ACCEPTANCES

         Certificates of deposit are certificates issued against funds deposited
in a banking institution for a specified period of time at a specified interest
rate. Bankers' acceptances are credit instruments evidencing a bank's obligation
to pay a draft drawn on it by a customer. These instruments reflect the
obligation both of the bank and of the drawer to pay the full amount of the
instrument upon maturity. Certain Funds will invest only in certificates of
deposit and bankers' acceptances of banks that have capital, surplus and
undivided profits in excess of $100 million.

                                COMMERCIAL PAPER

         Commercial paper consists of short-term, unsecured promissory notes
issued to finance short-term credit needs. The Funds will only invest in
commercial paper that at the time of purchase is rated Prime-1 or Prime-2 by
Moody's, A-1 or A-2 by S&P, "Duff 2" or higher by Duff & Phelps Credit Rating
Co. ("Duff"), or "F2" or higher by Fitch or if unrated by Moody's, S&P, Duff or
Fitch, is 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
ratings.

                              REPURCHASE AGREEMENTS

         Repurchase agreements are instruments under which a buyer acquires
ownership of a security from a seller that agrees to repurchase the security at
a mutually agreed upon time and price (which price is higher than the purchase
price), thereby determining the yield during the buyer's holding period. Under
the Investment Company Act of 1940, as amended (the "1940 Act"), a


                                       7
<PAGE>   32
repurchase agreement is deemed to be a Fund's loan of money to the seller,
collateralized by the underlying security. The interest rate is effective for
the period of time in which the Funds are invested in the agreement and is not
related to the coupon rate on the underlying security. Any repurchase agreements
a Fund enters into will involve the Fund as the buyer and banks or
broker-dealers as sellers (repurchase agreements with broker-dealers will be
limited to obligations of the U.S. Government or its agencies or
instrumentalities). The period of these repurchase agreements will be usually
short--from overnight to one week--and at no time will the Funds invest in
repurchase agreements for more than one year. However, securities subject to
repurchase agreements may have maturity dates in excess of one year from the
effective date of the repurchase agreements. The transaction requires the
initial collateralization of the seller's obligation with securities having a
market value, including accrued interest, equal to at least 102% of the dollar
amount the Funds invest with the value marked-to-market daily to maintain 100%
coverage. A default by the seller might cause the Funds to experience a loss or
delay in the liquidation of the collateral securing the repurchase agreement.
The Funds might also incur disposition costs in liquidating the collateral. The
Funds will make payment for such securities only upon physical delivery or
evidence of book entry transfer to the account of its custodian bank. The Funds
may not enter into a repurchase agreement of more than seven days duration if,
as a result, the market value of the Funds' net assets, together with
investments in other securities deemed to be not readily marketable, would be
invested in excess of the Funds' policy on investments in illiquid securities.

         In the event of a bankruptcy or other default of a repurchase
agreement's seller, a Fund might incur expenses in enforcing its rights, and
could experience losses, including a decline in the value of the underlying
securities and loss of income. Each Fund will not invest more than 15% of its
net assets at the time of purchase in repurchase agreements maturing in more
than seven days and other illiquid securities.

                                 SWAP AGREEMENTS

         Swap agreements can be structured to increase or decrease a Fund's
exposure to long- or short-term interest rates, mortgage securities, corporate
borrowing rates or other conditions, such as security prices or inflation rates.
For example, if a Fund agreed to pay a fixed rate in exchange for a floating
rate while holding fixed-rate bonds, the swap would tend to decrease the Fund's
exposure to long-term interest rates. Swap agreements tend to increase or
decrease the overall volatility of a Fund's investments and its share price and
yield. Changes in interest rates, or other factors determining the amount of
payments due to and from a Fund, can be the most significant factors in the
performance of a swap agreement. If a swap agreement calls for payments from a
Fund, the Fund must be prepared to make such payments when they are due. In
order to help minimize risks, each Fund will segregate appropriate assets for
any accrued but unpaid net amounts owed under the terms of a swap agreement
entered into on a net basis. All other swap agreements will require a Fund to
segregate appropriate assets in the amount of the accrued amounts owned under
the swap. A Fund could sustain losses if a counterparty does not perform as
agreed under the terms of the swap. Each Fund will enter into swap agreements
with counterparties deemed creditworthy by the Investment Manager.

                               PORTFOLIO MATURITY

         From time to time, the Funds may compare their average portfolio
maturities with the average portfolio maturities of other mutual funds having
similar investment objectives.


                                       8
<PAGE>   33
                          PORTFOLIO SECURITIES LENDING

         Loans of portfolio securities made by any Fund will be fully
collateralized by U.S. Government securities, letters of credit, cash or cash
equivalents and will be marked to market daily.

         FUTURES AND OPTIONS CONTRACTS AND INDEX PARTICIPATION CONTRACTS

         The Funds may buy and sell futures contracts on securities and any
index comprised of securities in which the Funds may invest, option contracts on
securities, indexes and futures contracts, and index participation contracts.

         In a securities futures contract, one party agrees to make, and the
other agrees to take, delivery of a specific amount of a specific security at a
specified time and price. Under a securities index futures contract, the parties
agree to make or take delivery of an amount of cash equal to a specific dollar
amount times the difference between the value of an agreed-upon securities index
at the end of the contract period and its value at the time the agreement was
originally made. Futures contracts are commonly "closed out" prior to the end of
the contract period by entering into an offsetting transaction in a
corresponding futures contract.

         Options on indexes are similar to options on securities except that,
rather than representing the right to take or make delivery of a security at a
specified exercise price, an option on a securities index gives the holder the
right to receive, upon exercise of the option, an amount of cash if the closing
level of the securities index upon which the option is based is "in the money."
This amount of cash is equal to the difference between the closing level of the
index and the exercise price of the option, expressed in dollars times a
specified multiple. Unlike securities options, all settlements are in cash, and
gain or loss depends on price movements in the group of securities comprising
the index rather than price movements of individual securities.

         Index participations and index participation contracts provide the
equivalent of a position in the securities comprising an index, with each
security's representation equaling its index weighting. Moreover, their holders
are entitled to payments equal to the dividends paid by the underlying index
securities. Generally, the value of an index participation or index
participation contract will rise and fall along with the value of the related
index. A Fund will invest in index participation contracts only if a liquid
market for them appears to exist.

         When buying or selling futures contracts, a Fund must deposit an amount
of cash, cash equivalents or liquid, high quality debt instruments with its
broker equal to a fraction of the contract amount. This amount is known as
"initial margin" and is in the nature of a performance bond or good faith
deposit on the contract, which will be returned to the Fund upon termination of
the futures contract, assuming all contractual obligations have been satisfied.
Subsequent payments to and from the broker, known as "variation margin," will be
made at least daily as the price of the futures contract fluctuates, and the
Fund's position in the contract becomes more or less valuable. This process is
known as "marking-to-market."

         Regulations of the Commodities Futures Trading Commission ("CFTC")
applicable to the Funds generally require that all of their futures transactions
constitute "bona fide" hedging transactions. As a result, a Fund will normally
sell futures contracts to protect against a decrease in the price of securities
it owns but intends to sell or purchase futures contracts to protect against an
increase in the price of securities it intends to purchase. In addition, the
Funds may purchase and


                                       9
<PAGE>   34
sell futures contracts and options as a substitute for a comparable market
position in the underlying securities. Futures transactions need not constitute
"bona fide" hedging under CFTC regulations if the aggregate initial margin and
premiums required to establish such positions do not exceed 5% of each Fund's
net assets.

         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.

         Risks Involved in Futures and Options Transactions. Futures and options
transactions involve risks, which in some strategies can be substantial due to
the low margin deposits required and the extremely high degree of leverage
involved in futures and options trading. However, to the extent the Funds'
futures and options practices are limited to use in tracking the performance of
a Fund's index, the Investment Manager does not believe that the Funds are
subject to the degree of risk frequently associated with futures and options
transactions. To the extent the Funds engage in the use of futures and options
on futures other than for performance tracking purposes, the Funds may be
subject to additional risk.

         Three principal areas of risk are present when futures and options
contracts are used in a performance tracking context. First, there may not
always be a liquid secondary market for a futures or option contract at the time
when a Fund seeks to "close out" its position. If a Fund is unable to "close
out" a futures or option position, and prices move adversely, the Fund would
have to continue to make daily cash payments to maintain its required margin,
and if the Fund has insufficient cash to meet this requirement, it may have to
sell portfolio securities at a disadvantageous time. In addition, the Fund might
be required to deliver the securities underlying futures or options contracts it
holds. Each Fund will seek to reduce the risk that it will be unable to "close
out" contracts by entering into only futures or options contracts that are
traded on national exchanges and for which there appears to be a liquid
secondary market.

         It is also possible that changes in the prices of futures or options
contracts might correlate imperfectly, or not at all, with changes in the market
values of the securities being hedged. This situation could result from price
distortions in the futures or options markets due to, among other things, active
trading by speculators and use of offsetting "closing" transactions by other
investors seeking to avoid meeting additional margin deposit requirements. In
the event of significant market distortions, it is possible that a Fund could
lose money on futures or options contracts and experience appreciation in the
value of its portfolio securities, or vice versa. The risk of imperfect
correlation will be minimized by investing only in those contracts whose
behavior is expected to resemble that of a Fund's underlying securities.

         Finally, adverse market movements could cause a Fund to lose up to its
full investment in an options contract and/or to experience substantial losses
on an investment in a futures contract. However, barring such significant market
distortions, a similar result could be expected were the Fund to invest directly
in the securities being hedged. There is also the risk of loss by a Fund of
margin deposits in the event of bankruptcy of a broker with whom the Fund has an
open position in a futures contract or option.

         The extent to which each Fund may purchase and sell futures, options,
equity index participations and index participation contracts may be limited by
each Fund's intention to meet the Internal Revenue Code of 1986, as amended (the
"Code"), requirements for qualification as a regulated investment company. See
"Taxes - Federal Income Tax."

                             INVESTMENT RESTRICTIONS

         The Following investment policies and restrictions are fundamental and
cannot be changed without approval of the holders of a majority of the
outstanding voting securities (as defined in the 1940 Act). All other investment
policies and restrictions contained in the SAI are non-fundamental and may be
changed without shareholder approval or prior notice.

EACH FUND MAY:

         1)            lend or borrow money to the extent permitted by the
                  Investment Company Act of 1940 or rules or regulations
                  thereunder, as such statute, rules or regulations may be
                  amended from time to time.

         2)            pledge, mortgage or hypothecate any of its assets to the
                  extent permitted by the Investment Company Act of 1940 or the
                  rules or regulations thereunder, as such statute, rules or
                  regulations may be amended from time to time.

         3)            not concentrate investments in a particular industry or
                  group of industries, or within one state (except with respect
                  to the Total Bond Fund and the Short Bond Fund, to the extent
                  that the index which each Fund seeks to track is also so
                  concentrated) as concentration is defined under the Investment
                  Company Act of 1940 or the rules or regulations thereunder, as
                  such statute, rules or regulations may be amended from time to
                  time.

         4)            underwrite securities to the extent permitted by the
                  Investment Company Act of 1940 or the rules or regulations
                  thereunder, as such statute, rules or regulations may be
                  amended from time to time.

         5)            not, as to 75% of the Fund's assets, purchase securities
                  of any issuer (other than obligations of, or guaranteed by,
                  the U.S. Government, its agencies or instrumentalities) if, as
                  a result more than 5% of the value of its total assets would
                  be invested in the securities of such issuer.

         6)            not invest for the purpose of exercising control or
                  management of another issuer.

         7)            not purchase securities of other investment companies,
                  except as permitted by the Investment Company Act of 1940.

         8)            issue senior securities to the extent permitted by the
                  Investment Company Act of 1940 or the rules or regulations
                  thereunder, as such statute, rules or regulations may be
                  amended from time to time.

         9)            purchase or sell commodities, commodities contracts,
                  futures contracts, or real estate to the extent permitted by
                  the Investment Company Act of 1940 or rules or regulations
                  thereunder, as such statute, rules or regulations may be
                  amended from time to time.

         The following description of the 1940 Act may assist investors in
understanding some of the above fundamental policies and restrictions.

         BORROWING. The 1940 Act presently restricts the Funds from borrowing
(including pledging, mortgaging or hypothecating assets) in excess of 33 1/3% of
their total assets (not including temporary borrowings not in excess of 5% of
total assets).

         LENDING. Under the 1940 Act, a Fund may only make loans if expressly
permitted by its investment policies.

         CONCENTRATION. The 1940 Act presently defines concentration as
investing 25% or more of the Fund's total assets in an industry or group of
industries with certain exceptions.

         UNDERWRITING. The 1940 Act presently limits a Fund's ability to
underwrite securities if, as a result, its underwriting commitments would exceed
25% of its total assets.

         The following investment policies and restrictions are non-fundamental
and may be changed by the Trust's Board of Trustees.

EACH FUND MAY NOT:

         1)            purchase more than 10% of any class of securities of any
                  issuer if, as a result of such purchase, it would own more
                  than 10% of such issuer's outstanding voting securities.

         2)            invest more than 5% of its total assets in securities of
                  issuers (other than obligations of, or guaranteed by the U.S.
                  Government, its agencies or instrumentalities) that with their
                  predecessors have a record of less than three years continuous
                  operation.

         3)            purchase securities that would cause more than 5% of its
                  net assets to be invested in restricted securities, excluding
                  restricted securities eligible for resale pursuant to Rule
                  144A under the Securities Act of 1933 that have been
                  determined to be liquid under procedures adopted by the
                  Trust's Board of Trustees based upon the trading markets for
                  the securities.

         4)            invest more than 5% of its net assets in warrants, valued
                  at the lower of cost or market, and no more than 40% of this
                  5% may be invested in warrants that are not listed on the New
                  York Stock Exchange or the American Stock Exchange, provided,
                  however, that for purposes of this restriction, warrants
                  acquired by a Fund in units or attached to other securities
                  are deemed to be without value.

         5)            purchase puts, calls, straddles, spreads or any
                  combination thereof if by reason of such purchase the value of
                  its aggregate investment in such securities would exceed 5% of
                  the Fund's total assets.

         6)            make short sales, except for short sales against the
                  box.


                                       12
<PAGE>   37
         7)              purchase or sell interests in oil, gas or other mineral
                  development programs or leases, although it may invest in
                  companies that own or invest in such interests or leases.

         8)              purchase securities on margin, except such short-term
                  credits as may be necessary for the clearance of purchases and
                  sales of securities.

         9)              lend money to any person, except that each Fund may (i)
                  purchase a portion of an issue of short-term debt securities
                  or similar obligations (including repurchase agreements) that
                  are publicly distributed or customarily purchased by
                  institutional investors, and (ii) lend its portfolio
                  securities.

         10)             borrow money, except from banks for temporary purposes
                  to satisfy redemption requests or for extraordinary or
                  emergency purposes and then only in an amount not to exceed
                  one-third of the value of its total assets (including the
                  amount borrowed), provided that the Fund will not purchase
                  securities while borrowings represent more than 5% of its
                  total assets.

         11)             pledge, mortgage or hypothecate any of its assets,
                  except that to secure allowable borrowing, each Fund may do so
                  with respect to no more than one-third of the value of its
                  total assets.

         12)             underwrite securities issued by others, except to the
                  extent it may be deemed to be an underwriter, under the
                  federal securities laws, in connection with the disposition of
                  securities from its investment portfolio.

         13)             purchase securities of any other issuer (other than
                  U.S. Government securities ) if, as a result , more than 25%
                  of its total assets would be invested in the securities if an
                  issuer from a single industry or group of industries.

         14)             purchase the securities of any issuer if, as a result
                  more than 15 % of its net assets would be invested in illiquid
                  securities.

         15)             purchase or sell commodities or real estate, including
                  interests in real estate limited partnerships, provided that
                  each Fund may (i) purchase securities of companies that deal
                  in real estate or interests therein, and (ii) purchase or sell
                  futures contracts, options contracts, equity index
                  participations and index participations contracts.

                       TRUSTEE DEFERRED COMPENSATION PLAN

         Pursuant to exemptive relief received by the Trust from the Securities
and Exchange Commission (the "SEC"), the Trust may enter into deferred fee
arrangements (the "Fee Deferral Plan" or the "Plan") with the Trust's Trustees
who are not "interested persons" of any of the Funds of the Trust (the
"Independent Trustees" or the "Trustees").


                                       17
<PAGE>   42
         As of the date of this Statement of Additional Information, none of the
Independent Trustees has elected to participate in the Fee Deferral Plan. In the
event an Independent Trustee does elect to participate in the Plan, the Plan
would operate as described below.

         Under the Plan, deferred Trustee's fees will be credited to a book
reserve account established by the Trust (the "Deferred Fee Account") as of the
date such fees would have been paid to such Trustee. The value of the Deferred
Fee Account as of any date will be equal to the value the Account would have had
as of that date if the amounts credited to the Account had been invested and
reinvested in the securities of the SchwabFund or SchwabFunds(R) selected by the
participating Trustee (the "Selected SchwabFund Securities"). SchwabFunds
include the series or classes of beneficial interest of the Trust, The Charles
Schwab Family of Funds and Schwab Capital Trust.

         Pursuant to the exemptive relief granted to the Trust, each Fund will
purchase and maintain the Selected SchwabFund Securities in an amount equal to
the deemed investments in that Fund of the Deferred Fee Accounts of the
Independent Trustees. The exemptive relief granted to the Trust permits the
Funds and the Trustees to purchase the Selected SchwabFund Securities, which
transactions would otherwise be limited or prohibited by the investment policies
and/or restrictions of the Funds. See "Investment Restrictions."

                               INVESTMENT MANAGER

         The Investment Manager, a wholly owned subsidiary of The Charles Schwab
Corporation, serves as the Funds' investment adviser and administrator pursuant
to an Investment Advisory and Administration Agreement (the "Advisory
Agreement") between it and the Trust. The Investment Manager is registered as an
investment adviser under the Investment Advisers Act of 1940, as amended, and
currently provides investment management services to the SchwabFunds Family(R),
a family of 31 mutual funds with over $60 billion in assets as of February 28,
1999. The Investment Manager is an affiliate of: Schwab; the Trust's
distributor; the shareholder services agent; and the transfer agent. The
Advisory Agreement will continue in effect until May 20, 1998 with respect to
each of the Funds, and thereafter will continue for one year terms subject to
annual approval by: (1) the Trust's Board of Trustees or (2) a vote of a
majority (as defined in the 1940 Act) of the outstanding voting securities of a
Fund. In either event, the continuance must also be approved by a majority of
the Trust's Board of Trustees who are not parties to the Agreement or interested
persons (as defined in the 1940 Act) of any such party by vote cast in person at
a meeting called for the purpose of voting on such approval. The Advisory
Agreement may be terminated at any time upon 60 days' notice by either party, or
by a majority vote of the outstanding shares of a Fund, and will terminate
automatically upon assignment.

         The Investment Manager and Schwab have guaranteed that, through at
least October 31, 1998, Short Bond Fund and Total Bond Fund will not exceed
0.38% and 30%, respectively, of each Fund's average daily net assets.

         For the fiscal years ended August 31, 1995, 1996 and 1997, the
investment advisory fees incurred by the Total Bond Fund, were $0 (fees were
reduced by $40,554), $0 (fees were reduced by $68,000) and $0 (fees were reduced
by $89,000), respectively.

         For the fiscal years ended August 31, 1995, 1996 and 1997, the
investment advisory fees incurred by the Short Bond Fund were $439,000 (fees
were reduced by $232,000), $453,000 (fees were reduced by $149,000) and $295,000
(fees were reduced by $234,000), respectively.

         From time to time, each Fund may compare its total operating expense
ratio to the total operating expense ratio of other mutual funds or mutual fund
averages with similar investment objectives as reported by Lipper Analytical
Service, Inc., Morningstar, Inc. or other independent sources of such
information ("independent sources").

                                   DISTRIBUTOR

         Pursuant to a Distribution Agreement, Schwab is the principal
underwriter for shares of the Trust and is the Trust's agent for the purpose of
the continuous offering of the Funds' shares. Each Fund pays the cost of the
prospectuses and shareholder reports to be prepared and delivered to existing
shareholders. Schwab pays such costs when the described materials are used in
connection with the offering of shares to prospective investors and for
supplementary sales literature and advertising. Schwab receives no fee under the
Distribution Agreement. Terms of continuation, termination and assignment under
the Distribution Agreement are identical to those described above with respect
to the Advisory Agreement.

                          CUSTODIAN AND FUND ACCOUNTANT

         PNC Bank, National Association, at the Airport Business Center, 200
Stevens Drive, Suite 440, Lester, Pennsylvania 19113, serves as Custodian for
the Trust.

         PFPC, Inc., at 103 Bellevue Parkway Wilmington, Delaware 19809, serves
as Fund Accountant for the Trust.

                     ACCOUNTANTS AND REPORTS TO SHAREHOLDERS

         The Trust's independent accountants, Price Waterhouse LLP, 555
California Street, California, 94104, audit and report on the annual financial
statements of each series of the Trust and review certain regulatory reports and
each Fund's federal income tax return. It also performs other professional
accounting, auditing, tax and advisory services when the Trust engages it to do
so. Shareholders will be sent audited annual and unaudited semi-annual financial
statements.

                       PORTFOLIO TRANSACTIONS AND TURNOVER

                             PORTFOLIO TRANSACTIONS

         The Funds paid no brokerage commissions for each such Fund's last three
fiscal years.

         Portfolio Brokerage. The Funds typically purchase and sell securities
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 judgement 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


                                       19
<PAGE>   44
transaction quality will be at least comparable to those available from other
qualified brokers or dealers.

                               PORTFOLIO TURNOVER

         For reporting purposes, each Fund's turnover rate is calculated by
dividing the value of purchases or sales of portfolio securities for the fiscal
year, whichever is less, by the monthly average value of portfolio securities
the Fund owned during the fiscal year. When the Fund makes the calculation, all
securities whose maturities at the time of acquisition were one year or less
("short-term securities") are excluded. A 100% portfolio turnover rate would
occur, for example, if all portfolio securities (aside from short-term
securities) were sold and either repurchased or replaced once during the fiscal
year.

         From time to time, each Fund may compare its portfolio turnover rate
with that of other mutual funds as reported by independent sources.

         The portfolio turnover rates for the Total Bond Fund for the fiscal
years ended August 31, 1996 and 1997 were 66% and 51%, respectively. The
portfolio turnover rates for the Short Bond Fund for the fiscal years ended
August 31, 1996 and 1997 were 80% and 71%, respectively.

         The Funds may experience higher portfolio turnover rates during their
transition to their new investment strategies. Higher turnover rates generally
mean higher transaction costs and may lead to higher taxable capital
gains/losses.

                                      TAXES

                               FEDERAL INCOME TAX

         It is each Fund's policy to qualify for taxation as a "regulated
investment company" by meeting the requirements of Subchapter M of the Code. By
following this policy, each Fund expects to eliminate or reduce to a nominal
amount the federal income tax to which it is subject.

         In order to qualify as a regulated investment company, each of the
Funds must, among other things, (1) derive at least 90% of its gross income from
dividends, interest, payments with respect to securities loans and gains from
the sale or other disposition of stocks, securities, foreign currencies or other
income (including gains from options, futures or forward contracts) derived with
respect to its business of investing in stocks, securities or currencies; (2)
for taxable years beginning on or before August 5, 1997 derive less than 30% of
its gross income from gains from the sale or other disposition of certain assets
(including stocks and securities) held for less than three months; and (3)
diversify its holdings so that at the end of each quarter of its taxable year
(i) at least 50% of the market value of the Fund's total assets is represented
by cash or cash items, U.S. Government securities, securities of other regulated
investment companies and other securities limited, in respect of any one issuer,
to a value not greater than 5% of the value of the Fund's total assets and 10%
of the outstanding voting securities of such issuer, and (ii) not more than 25%
of the value of its assets is invested in the securities of any one issuer
(other than U.S. Government securities or securities of any other regulated
investment company) or of two or more issuers that the Fund controls, within the
meaning of the Code, and that are engaged in the same, similar or related trades
or businesses. These requirements may restrict the degree to which a Fund may
engage in certain hedging transactions and may limit the range of a Fund's
investments. If a Fund qualifies as a regulated investment company, it will not
be subject to federal income tax on the part of its net investment


                                       20
<PAGE>   45
income and net realized capital gains, if any, which it distributes to
shareholders, provided that the Fund meets certain minimum distribution
requirements. To comply with these requirements, a Fund must distribute at least
(a) 90% of its "investment company taxable income" (as that term is defined in
the Code) and (b) 90% of the excess of its (i) tax-exempt interest income over
(ii) certain deductions attributable to that income (with certain exceptions),
for its taxable year. Each Fund intends to make sufficient distributions to
shareholders to meet these requirements.

         The Code imposes a non-deductible excise tax on regulated investment
companies that do not distribute in a calendar year (regardless of whether they
otherwise have a non-calendar taxable year) an amount equal to 98% of their
"ordinary income" (as defined in the Code) for the calendar year plus 98% of
their capital gain net income for the one-year period ending on October 31 of
such calendar year, plus any undistributed amounts from prior years. For the
foregoing purposes, a Fund is treated as having distributed any amount on which
it is subject to income tax for any taxable year ending in such calendar year.
If the distributions during a calendar year are less than the required amount,
the Fund is subject to a non-deductible excise tax equal to 4% of the
deficiency.

         Any dividends declared by the Funds in October, November or December to
shareholders of record during those months and paid during the following January
are treated, for tax purposes, as if they were received by each shareholder on
December 31 of the year declared. A Fund may adjust its schedule for the
reinvestment of distributions for the month of December to assist in complying
with the reporting and minimum distribution requirements of the Code.

         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 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 six months or less shall be treated as a
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.

         A Fund will be required in certain cases to withhold and remit to the
U.S. Treasury 31% of taxable dividends paid to any shareholder who (1) fails to
provide a correct taxpayer identification number certified under penalty of
perjury; (2) is subject to withholding by the Internal Revenue Service for
failure to properly report all payments of interest or dividends; or (3) fails
to provide a certified statement that he or she is not subject to "backup
withholding." This "backup withholding" is not an additional tax and any amounts
withheld may be credited against the shareholder's ultimate U.S. tax liability.

         A Fund's transactions in futures contracts and options and certain
other investment and hedging activities are subject to special tax rules. In a
given case, these rules may accelerate income to a Fund, defer its losses, cause
adjustments in the holding periods of the Fund's assets, convert short-term
capital losses into long-term capital losses or otherwise affect the character
of the Fund's income. These rules could therefore affect the amount, timing and
character of distributions to shareholders. Income earned as a result of these
transactions would, in general, not be eligible for the corporate dividends
received deduction when distributed to corporate shareholders. The Funds will
endeavor to make any available elections pertaining to these transactions in a
manner believed to be in the best interest of the Funds and their shareholders.


                                       21
<PAGE>   46
         The foregoing discussion relates only to federal income tax law as
applicable to U.S. citizens or residents. Foreign shareholders (i.e.,
nonresident alien individuals and foreign corporations, partnerships, trusts and
estates) are generally subject to U.S. withholding tax at the rate of 30% (or a
lower tax treaty rate) on distributions derived from net investment income and
short-term capital gains. Distributions to foreign shareholders of long-term
capital gains and any gains from the sale or other disposition of shares of the
Funds are generally not subject to U.S. taxation, unless the recipient is an
individual who meets the Code's definition of "resident alien." Different tax
consequences may result if the foreign shareholder is engaged in a trade or
business within the United States. In addition, the tax consequences to a
foreign shareholder entitled to claim the benefits of a tax treaty may be
different than those described above. Distributions by a Fund may also be
subject to state, local and foreign taxes, and their treatment under applicable
tax laws may differ from the federal income tax treatment.

         The Funds may experience higher investment costs resulting from taxable
capital gains/losses from selling securities during the transition from actively
managed portfolios to indexing investment strategies.

                             SHARE PRICE CALCULATION

         Each Fund's net asset value per share is determined each day the New
York Stock Exchange (NYSE) is open for trading as of 4:00 p.m. Eastern time. The
NYSE may change its holiday closing schedule at anytime, but the following
holiday closings are currently schedule for 1998: New Year's Day, Dr. Martin
Luther King's Birthday (observed), President's Day, Good Friday, Memorial Day,
Labor Day, Thanksgiving Day and Christmas Day. On any day that the New York
Stock Exchange or principal government securities markets closes early, such as
days in advance or holidays, the Funds reserve the right to advance the time by
which purchase, redemption and exchange orders must be received on that day.
Shares purchased begin to earn dividends on the next business day with the
following exceptions: Columbus Day and Veterans Day. The Funds value their
portfolio securities daily based on their fair value. Securities traded on stock
exchanges are valued at the last quoted sales price on the exchange on which
such securities are primarily traded, or, lacking any sales, at the mean between
the bid and ask prices.

         Investments in mutual funds are valued at their respective net asset
values, as determined by those funds. Securities traded in the over-the-counter
market are valued at the last sales price that day, or if no sales that day, at
the mean between the bid and ask prices. In addition, securities that are
primarily traded on foreign exchanges are generally valued at the preceding
closing values of such securities on their respective exchanges with these
values then translated into U.S. dollars at the current exchange rate. Foreign
securities for which the closing values are not readily available are valued at
fair value as determined in good faith pursuant to the Board of Trustees
guidelines. Securities for which market quotations are not readily available
(including restricted securities that are subject to limitations on their sale)
are valued at fair value as determined in good faith pursuant to the Trust's
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.

         From time to time, each Fund may report its net asset value per share
over a specified period. Each Fund's net asset value, for the periods set forth,
may be compared to net asset


                                       22
<PAGE>   47
values for other mutual funds with similar investment objectives as reported by
independent sources.

                             TOTAL RETURN AND YIELD

                            STANDARDIZED TOTAL RETURN

         Average annual total return for a period is determined by calculating
the actual dollar amount of investment return on a $1,000 investment in a Fund
made at the beginning of the period, then calculating the average annual
compounded rate of return that would produce the same investment return on the
$1,000 over the same period. In computing average annual total return, a Fund
assumes the reinvestment of all distributions at net asset value on applicable
reinvestment dates.

                          NONSTANDARDIZED TOTAL RETURN

         Nonstandardized total return for a Fund differs from standardized total
return in that it relates to periods other than the period for standardized
total return and/or that it represents aggregate (rather than average) total
return.

         A Fund may also advertise its cumulative total return since inception.
This number is calculated using the same formula that is used for average annual
total return except that, rather than calculating the total return based on a
one-year period, cumulative total return is calculated from inception to the
date specified.

                                      YIELD

         A Fund's yield refers to the net investment income generated by a
hypothetical investment in the Fund over a specific 30-day period. This net
investment income is then annualized, which means that the net investment income
generated during the 30-day period is assumed to be generated in each 30-day
period over an annual period, and is shown as a percentage of the investment.

                                 EFFECTIVE YIELD

         A Fund's effective yield is calculated similarly, but the net
investment income earned by the investment is assumed to be compounded monthly
when annualized. The effective yield will be slightly higher than the yield due
to this compounding effect.

                             COMPARATIVE PERFORMANCE

         Each Fund's performance may be compared to various unmanaged bond
indexes in addition to the Lehman Brothers Short (1-5) Government/Corporate
Index and the unmanaged Lehman Brothers Aggregate Bond Index, 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. rankings.

                               GENERAL INFORMATION

         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.

         Shares 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 election of trustees.

         The Trust generally is not required to hold shareholder meetings.
However, as provided in its Agreement and Declaration of Trust and Bylaws,
shareholder meetings will be held in connection with the following matters: (1)
removal of Trustees if a meeting is requested in writing by a shareholder or
shareholders who beneficially own(s) 10% or more of the Trust's shares; (2)
adoption of any contract for which shareholder approval is required by the 1940
Act; (3) any


                                       24
<PAGE>   49
termination of the Trust to the extent and as provided in the Declaration of
Trust; (4) any amendment of the Declaration of Trust (other than amendments
changing the name of the Trust or any of its investment portfolios, supplying
any omission, curing any ambiguity or curing, correcting or supplementing any
defective or inconsistent provision thereof); (5) determining whether a court
action, proceeding or claim should or should not be brought or maintained
derivatively or as a class action on behalf of the Trust or the shareholders, to
the same extent as the stockholders of a Massachusetts business corporation; and
(6) such additional matters as may be required by law, the Declaration of Trust,
the Bylaws or any registration of the Trust with the SEC or any state or as the
Board of Trustees may consider desirable. The shareholders also would vote upon
changes to a Fund's fundamental investment objective, policies or restrictions.

         Each Trustee serves until the next meeting of shareholders, if any,
called for the purpose of electing Trustees and until the election and
qualification of his or her successor or until death, resignation, retirement or
removal by a majority vote of the shares entitled to vote (as described below)
or of a majority of the Trustees. In accordance with the 1940 Act, (i) the Trust
will hold a shareholder meeting for the election of Trustees when less than a
majority of the Trustees have been elected by shareholders and (ii) if, as a
result of a vacancy in the Board of Trustees, less than two-thirds of the
Trustee have been elected by the shareholders, that vacancy will be filled by a
vote of the shareholders.

         Upon the written request of 10 or more shareholders who have been such
for at least six months and who hold shares constituting at least 1% of the
Trust's outstanding shares stating that they wish to communicate with the other
shareholders for the purpose of obtaining signatures necessary to demand a
meeting to consider removal of one or more Trustees, the Trust has undertaken to
disseminate appropriate materials at the expense of the requesting shareholders.

         The Bylaws provide that the presence at a shareholder meeting in person
or by proxy of at least 30% of the shares entitled to vote on a matter shall
constitute a quorum, unless otherwise provided by the 1940 Act or other
applicable law. Thus, even if less than a majority of shareholders were
represented, a meeting of the Trust's shareholders could occur. Attending
shareholders would in such case be permitted to take action not requiring the
vote of more than a majority of a quorum. Some matters requiring a larger vote
under the Declaration of Trust, such as termination or reorganization of the
Trust, and certain amendments of the Declaration of Trust, could not be decided
at such a meeting; nor could matters which under the 1940 Act require the vote
of a "majority of the outstanding voting securities" as defined in the 1940 Act.
The Declaration of Trust specifically authorizes the Board of Trustees to
terminate the Trust (or any of its investment portfolios) by notice to the
shareholders without shareholder approval.

         Under Massachusetts law, shareholders of a Massachusetts business trust
could, under certain circumstances, be held personally liable for the Trust's
obligations. The Declaration of Trust, however, disclaims shareholder liability
for the Trust's acts or obligations and requires that notice of such disclaimer
be given in each agreement, obligation or instrument entered into or executed by
the Trust or the Trustees. In addition, the Declaration of Trust provides for
indemnification out of the property of an investment portfolio in which a
shareholder owns or owned shares for all losses and expenses of such shareholder
or former shareholder if he or she is held personally liable for the obligations
of the Trust solely by reason of being or having been a shareholder. Moreover,
the Trust will be covered by insurance which the Trustees consider adequate to
cover foreseeable tort claims.


                                       25
<PAGE>   50
         Thus, the risk of a shareholder incurring financial loss on account of
shareholder liability is considered remote, because it is limited to
circumstances in which a disclaimer is inoperative and the Trust itself is
unable to meet its obligations.

                         PRINCIPAL HOLDERS OF SECURITIES

         As of February 28, 1998, Charles Schwab Trust Company, 101 Montgomery
street, San Francisco, California 94104 directly or beneficially owned
approximately 5.3% of the Short Bond Fund. Also on this date, Morgan Stanley
Trust Company as custodian for the Schwab Asset Director(R) - Balanced Growth
Fund and Schwab Asset Director - Conservative Growth Fund, 1 Pierrepont Plaza,
Brooklyn, NY 11201, respectively, directly or beneficially owned approximately
40% and 22% of the outstanding shares of the Total Bond Fund.

         In addition, as of March 10, 1998 the officers and trustees of the
Trust, as a group, owned less than 1% of each Fund's outstanding voting
securities.

         For further information, please refer to the registration statement and
exhibits for the Trust on file with the SEC in Washington, D.C. and available
upon payment of a copying fee. The statements in the Prospectus and this
Statement of Additional Information concerning the contents of contracts or
other documents, copies of which are filed as exhibits to the registration
statement, are qualified by reference to such contracts or documents.

                        PURCHASE AND REDEMPTION OF SHARES

         Each Fund has set minimum initial and subsequent investment
requirements, as disclosed in the Prospectus. These minimum investment
requirements may be changed at any time and are not applicable to certain types
of investors. The Trust may waive the minimums for purchases by Trustees,
Directors, officers or employees of the Trust, Schwab or the Investment Manager.

         The Trust has made an election with the SEC to pay in cash all
redemptions requested by any shareholder of record limited in amount during any
90-day period to the lesser of $250,000 or 1% of its net assets at the beginning
of such period. This election is irrevocable without the SEC's prior approval.
Redemption requests in excess of the stated limits may be paid, in whole or in
part, in investment securities or in cash, as the Trust's Board of Trustees may
deem advisable; however, payment will be made wholly in cash unless the Board of
Trustees believes that economic or market conditions exist that would make such
a practice detrimental to the best interests of the Fund. If redemption proceeds
are paid in investment securities, such securities will be valued as set forth
in the Prospectus of the Fund affected under "Share Price Calculation" and a
redeeming shareholder would normally incur brokerage expenses if he or she were
to convert the securities to cash.

         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.

         Payment for redeemed shares will be credited directly to your Schwab
account no later than 7-days after the Fund or Schwab 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.


                                       26
<PAGE>   51
         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 and purchase of the shares for federal income tax purposes.

         Due to the relatively high cost of maintaining accounts with smaller
holdings, each Fund reserves to 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 minimum balance requirement. 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.

                   APPENDIX - RATINGS OF INVESTMENT SECURITIES

         Lower-quality debt securities are sometimes referred to as "junk
bonds," and are considered more speculative and subject too greater risk. Some
junk bonds may already be in default, i.e., failed to meet their interest and/or
principal payment obligations. From time to time, each Fund may report the
percentage of its assets which fall into the rating categories set forth below.

                                      BONDS

                            MOODY'S INVESTORS SERVICE

         Moody's rates the bonds it judges to be of the best quality Aaa. These
bonds carry the smallest degree of investment risk and are generally referred to
as "gilt edge." Interest payments are protected by a large or exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of these issues. Bonds carrying an Aa
designation are deemed to be of high quality by all standards. Together with Aaa
rated bonds, they comprise what are generally known as high grade bonds. Aa
bonds are rated lower than the best bonds because they may enjoy relatively
lower margins of protection, fluctuations of protective elements may be of
greater amplitude or there may be other factors present which make them appear
to be subject to somewhat greater long-term risks. A rated bonds are considered
as upper-medium grade obligations as they possess many favorable investment
attributes. Bonds designated Baa are considered medium grade in that they are
not highly protected nor poorly secured. Interest payments and principal
security appear to be adequate at the present, but they may lack certain
protective elements or be characteristically unreliable over any great length of
time. Baa bonds do not have any outstanding investment characteristics and do
have speculative characteristics.

                          STANDARD & POOR'S CORPORATION

         AAA is the highest rating assigned by S&P to a bond and indicates the
issuer's extremely strong capacity to pay interest and repay principal. An AA
rating denotes a bond whose issuer has a very strong capacity to pay interest
and repay principal and differs from an AAA rating only in small degree. A
ratings are given to debt which has a strong capacity to pay interest and repay
principal but is somewhat more susceptible to adverse effects of changes in
circumstances and economic conditions than higher rated debt. BBB debt indicates
the issuer is regarded by S&P as having an adequate capacity to pay interest and
repay principal. These securities appear to have adequate protection, however
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity to pay interest and repay principal in this category than in
higher categories.

                         DUFF & PHELPS CREDIT RATING CO.

         Duff confers an AAA designation to bonds of issuers with the highest
credit quality. The risk factors associated with these bonds are negligible,
being only slightly more than for risk-free U.S. Treasury debt. AA rated bonds
are of high credit quality and have strong protection factors. The risks
associated with them are modest but may vary slightly from time to time because
of economic conditions. An A rating indicates that the protection factors are
average but adequate. The risk factors, however, are more variable and greater
in periods of economic stress. BBB rated debt has protection factors that are
below average but still sufficient for prudent investment. There is considerable
variability in the risk of BBB rated debt during economic cycles.

                          FITCH INVESTOR SERVICES, INC.

         AAA is the highest rating Fitch assigns to bonds, and indicates the
obligor's exceptionally strong ability to pay interest and repay principal.
Bonds which Fitch considers of very high credit quality, and the obligor's
ability to pay interest and repay principal is very strong, although not as
strong as AAA, is rated AA. An A rating is given to show high credit quality and
the issuer's ability to pay interest and repay principal is strong, but there is
more vulnerability to economic conditions and circumstances than higher rated
debt. BBB bonds are considered investment grade, where the issuer has adequate
ability to pay interest and repay principal. Bonds rated BBB are more
susceptible to adverse changes in economic conditions and circumstances, thus
these bonds are more likely to fall below investment grade or have the
timeliness of their payments impaired.

              SHORT-TERM NOTES AND VARIABLE RATE DEMAND OBLIGATIONS

                            MOODY'S INVESTORS SERVICE

         Short-term notes/variable rate demand obligations bearing the
designations MIG-1/VMIG-1 are considered to be of the best quality, enjoying
strong protection from established cash flows, superior liquidity support or
demonstrated broad-based access to the market for refinancing. Obligations rated
MIG-2/VMIG-3 are of high quality and enjoy ample margins of protection although
not as large as those of the top rated securities.

                          STANDARD & POOR'S CORPORATION

         An S&P SP-1 rating indicates that the subject securities' issuer has a
strong capacity to pay principal and interest. Issues determined to possess very
strong safety characteristics are given a plus (+) designation. S&P's
determination that an issuer has a satisfactory capacity to pay principal and
interest is denoted by an SP-2 rating.

                                      IBCA

         Obligations supported by the highest capacity for timely repayment are
rated A1+. An A1 rating indicates that the obligation is supported by a very
strong capacity for timely repayment. Obligations rated A2 are supported by a
good capacity for timely repayment, although adverse changes in business,
economic, or financial conditions may affect this capacity.

                                COMMERCIAL PAPER

                            MOODY'S INVESTORS SERVICE

         Prime-1 is the highest commercial paper rating assigned by Moody's.
Issuers (or related supporting institutions) of commercial paper with this
rating are considered to have a superior ability to repay short-term promissory
obligations. Issuers (or related supporting institutions) of securities rated
Prime-2 are viewed as having a strong capacity to repay short-term promissory
obligations. This capacity will normally be evidenced by many of the
characteristics of issuers whose commercial paper is rated Prime-1 but to a
lesser degree.

                          STANDARD & POOR'S CORPORATION

         A Standard & Poor's Corporation ("S&P") A-1 commercial paper rating
indicates a strong degree of safety regarding timely payment of principal and
interest. Issues determined to possess overwhelming safety characteristics are
denoted A-1+. Capacity for timely payment on commercial paper rated A-2 is
satisfactory, but the relative degree of safety is not as high as for issues
designated A-1.

                         DUFF & PHELPS CREDIT RATING CO.

         Duff-1 is the highest commercial paper rating assigned by Duff. Three
gradations exist within this rating category: A Duff-1+ rating indicates the
highest certainty of timely payment (issuer short-term liquidity is found to be
outstanding and safety is deemed to be just below that of risk-free short-term
U.S. Treasury obligations), a Duff-1 rating signifies a very high certainty of
timely payment (issuer liquidity is determined to be excellent and risk factors
are considered minor) and a Duff-1- rating denotes high certainty of timely
payment (issuer liquidity factors are strong and risk is very small). A Duff-2
rating indicates a good certainty of timely payment. Liquidity factors and
company fundamentals are sound and risk factors are small.

                          FITCH INVESTORS SERVICE, INC.

         F-1+ is the highest category, and indicates the strongest degree of
assurance for timely payment. Issues rated F-1 reflect an assurance of timely
payment only slightly less than issues rated F-1+. Issues assigned an F-2 rating
have a satisfactory degree of assurance for timely payment, but the margin of
safety is not as great as for issues in the first two rating categories.

                    COMMERCIAL PAPER, SHORT-TERM OBLIGATIONS
                     AND DEPOSIT OBLIGATIONS ISSUED BY BANKS

                             THOMSON BANKWATCH (TBW)

         TBW-1 is the highest category and indicates the degree of safety
regarding timely repayment of principal and interest is very high. TBW-2 is the
second highest category and while the degree of safety regarding timely
repayment of principal and interest is strong, the relative degree of safety is
not as high as for issues rated "TBW-1."
