HOW TO READ THE FINANCIAL HIGHLIGHTS

After each Fund's Investment Objective and Investment Policies, charts are
provided showing important financial information about Fund. The charts are
called "Financial Highlights" and are designed to help you understand the past
performance of each Fund. The financial statements, from which these Financial
Highlights were derived, were audited by KPMG Peat Marwick LLP except as
indicated. The financial statements are available in the Fund's most recent
Annual Report and are available free of charge by calling 1-800-222-8222. for
periods prior to October 1, 1995 and for the Growth Fund prior to January 1,
1992.  Here is an explanation of some terms that will help you interpret these
charts.

NET ASSET VALUE (NAV)--The value of one share of a class of a Fund, excluding
any sales charge. See the Glossary for a fuller definition.

NET INVESTMENT INCOME--When we receive dividend or interest payments from an
investment or earn trading profits, we deduct management fees, administrative
and other expenses and then record the result as net investment income. The
number in the financial highlights is the net investment income of a class
divided by the number of outstanding shares of that class. The amount
distributed to shareholders is listed under the heading "Less Distributions-
Dividends from Net Investment Income."

NET REALIZED AND UNREALIZED CAPITAL GAINS--We buy and sell investments
frequently. The profit on an investment sold for more than its purchase price is
a realized capital gain while any loss is a realized capital loss. An unrealized
gain or loss occurs when an investment gains or loses value but is not sold. The
number in this category is the total gains or losses of a class divided by the
number of outstanding fund shares for that class. The amount of capital gain or
loss per share that was passed on to shareholders is listed under the heading
"Less Distributions-Distributions From Net Realized Gains."

NET ASSETS--The value of the investments in a Fund's portfolio that are
attributable to a particular class of the Fund.

RATIO OF EXPENSES TO AVERAGE NET ASSETS--This ratio reflects the amount paid by
a Fund to cover the costs of its daily operations, and includes advisory,
administrative and other operating expenses. It is expressed as a percentage of
the average daily net assets of a class.

RATIO OF NET INVESTMENT INCOME (LOSS) TO AVERAGE NET ASSETS--This ratio is the
result of dividing net investment income (or loss) by average net assets.

PORTFOLIO TURNOVER--Portfolio turnover reflects the trading activity in the
Fund's portfolio and is expressed as a percentage of a Fund's investment
portfolio. For example, a Fund with a 50% portfolio turnover has sold and bought
half of its investment portfolio during the given period.

AVERAGE COMMISSION RATE PAID--The average brokerage commission paid by a Fund
when it buys or sells shares of securities. The rate is expressed on a per share
basis and the amount paid may vary depending upon trading practices or other
conditions. This information is required for fiscal years beginning after
September 1, 1995

TOTAL RETURN--The annual return on an investment, including any appreciation or
decline in share value, assumes reinvestment of all dividends and capital gains,
and excludes sales loads.

CLASS A SHARE ANNUAL RETURNS (Bar graph with caption) Returns for other share
classes may vary due to different fees and expenses. These returns do not
reflect sales loads and are not a guarantee of future performance.

INVESTMENT OBJECTIVE

          The Balanced Fund seeks to provide investors with both capital
appreciation and current income resulting in a high total investment return
consistent with prudent investment risk and a balanced investment approach.

INVESTMENT POLICIES

          We pursue a balanced and diversified investment approach by investing
generally between 30% and 70% of our assets in common stocks and the remainder
in fixed-income securities. By actively managing both the equity and fixed-
income portfolios and the allocation mix, we hope to achieve a high total
return, including share Growth distributions. We invest the equity portion of
our portfolio according to the same value strategy discussed in the Equity Value
Fund section on page ___ of this Prospectus. We invest the fixed-income portion
of our portfolio in corporate bonds, commercial paper, and mortgage-backed and
asset-backed securities based on their relatively greater stability of income
and principal.
 
PORTFOLIO HOLDINGS

Under normal market conditions, we invest:
 .  between 30% and 70% of our assets in common stocks, with the remainder
   invested in fixed-income securities.

The equity portion of the portfolio, under normal market conditions, is invested
in:
 .  both large, well-established companies and smaller companies with market
   capitalization exceeding $50 million; and
 .  in foreign companies through American Depository Receipts and similar
   instruments, up to 25% of total assets.

We invest the fixed-income portion of our portfolio in:
 .  commercial paper rated "A-2" (S&P) or "Prime-2" (Moody's) or better;
 .  corporate debt securities rated "BBB" (S&P) or "Baa" (Moody's) or better;
 .  mortgage-backed and asset-backed securities rated "AA" (S&P) or "Aa"
   (Moody's) or better.

We may also invest in zero-coupon bonds.

          We may temporarily hold assets in cash or in money market instruments,
including U.S. Government obligations, shares of other mutual funds and
repurchase agreements, or make other short-term investments, either to maintain
liquidity or for short-term defensive purposes when we believe it is in the best
interest of shareholders to do so.

IMPORTANT RISK FACTORS

Historically, stock and bond markets have often had different cycles, with one
asset class rising when the other is falling. A balanced objective attempts to
reduce the volatility associated with investing in a single market. There is no
guarantee, however, that market cycles will move in opposition to one another or
that a balanced investment program will successfully reduce volatility. Also,
stocks of smaller and medium-sized companies may be more volatile than larger
company stocks. Investments in foreign markets may also present special risks,
including currency, political, diplomatic, regulatory and liquidity risks.

ADDITIONAL FUND FACTS

Tamyra Thomas is the manager of the income portion of the Fund, Rex Wardlaw is
the manager of the equity portion. They jointly determine the portfolio's asset
allocation.

Portfolio Managers:  Allen Wisniewski (since 9/96)

CLASS A SHARE ANNUAL RETURNS (Bar graph with caption) Returns for other share
classes may vary due to different fees and expenses. These returns do not
reflect sales loads and are not a guarantee of future performance.

INVESTMENT OBJECTIVE

          The Equity Value Fund seeks to provide investors with long-term
capital appreciation.

INVESTMENT POLICIES

          We seek long-term capital appreciation by investing in a diversified
portfolio composed primarily of equity securities that we believe are selling
for less than their intrinsic or true value and that generally exhibit the
following characteristics: above-average financial strength, a strong position
in their industry and a history of steady profit growth. We use both
quantitative and qualitative analysis to identify possible investments.
Dividends are a secondary consideration when selecting stock. We may purchase
particular stocks when we believe that a history of strong dividends may
increase their market value.

PORTFOLIO HOLDINGS

Under normal market conditions, we invest:
 .  primarily in common stocks of both large, well-established companies and
   smaller companies with market capitalizations exceeding $50 million;
 .  in debt instruments that may be converted into the common stock of both U.S.
   and foreign companies; and
 .  up to 25% of our assets in foreign companies through American Depository
   Receipts and similar instruments.

We may also purchase convertible securities with the same characteristics as
common stock, as well as in preferred stock and warrants. We may temporarily
hold assets in cash or in money market instruments, including U.S. Government
obligations, shares of other mutual funds and repurchase agreements, or make
short-term investments, either to maintain liquidity or for short-term defensive
purposes when we believe it is in the best interests of shareholders.

IMPORTANT RISK FACTORS:

For general risk information, please see page _____.

Stocks of smaller and medium-sized companies may be more volatile than larger
company stocks. Investments in foreign markets may also present special risks,
including currency, political, diplomatic, regulatory and liquidity risks.

ADDITIONAL FUND FACTS: Our strategy of buying attractive stocks which appear to
be selling for less than their intrinsic value is commonly known as a "value"
strategy.

CLASS A SHARE ANNUAL RETURNS (Bar graph with caption) Returns for other share
classes may vary due to different fees and expenses. These returns do not
reflect sales loads and are not a guarantee of future performance.

INVESTMENT OBJECTIVE

          The Growth Fund seeks to earn current income and achieve long-term
capital appreciation by investing primarily in common stocks and preferred
stocks and debt securities that are convertible into common stocks.

INVESTMENT POLICIES

          We actively manage a diversified portfolio of common stock and other
equities. In selecting stocks, we emphasize past and potential future dividends.
We look for companies that have a strong earnings growth trend that we believe
have above-average prospects for future growth, and that have historically paid
above-average dividends. We especially look for common stocks that are trading
at low price-to-earnings ratios, as measured against either the stock market as
a whole or against the stock's own price history.

          We may also invest in the stocks of medium- to smaller-size companies
that we believe have the potential to produce high levels of future earnings
growth or when we believe the stock is undervalued.

PORTFOLIO HOLDINGS
 
Under normal market conditions, we invest:
 .  at least 65% of our total assets in equity securities, including common and
   preferred stock, and securities convertible into common stocks;
 .  at least 65% of our total assets in income producing securities;
 .  up to 50% of our assets in smaller- and medium-sized companies, with the
   remainder in larger companies;
 .  up to 25% of our assets in American Depository Receipts and similar
   instruments; and
 .  up to 15% of our assets in emerging markets.

   We may temporarily hold assets in cash or in money market instruments,
including U.S. Government obligations, shares of other mutual funds and
repurchase agreements, or make short-term investments, either to maintain
liquidity or for short-term defensive purposes when we believe it is in the best
interest of shareholders to do so.

IMPORTANT RISK FACTORS

Please see the general risks section beginning on page ____.

Smaller and medium-sized companies selected for their earnings growth potential
may be more volatile than larger company stocks. Investments in foreign and
emerging markets may also present special risks, including currency, political,
diplomatic, regulatory and liquidity risks.

ADDITIONAL FUND FACTS

We have a quarterly dividend policy. This Fund would not be suitable for
investors requiring monthly income

Small Cap Fund

Portfolio Managers: Jon Hickman (since 9/96)
- -------------------                         
                    Steve Enos (since 9/96)
                    Kenneth Lee (since 6/97)

CLASS A SHARE ANNUAL RETURNS (Bar graph with caption) Returns for other share
classes may vary due to different fees and expenses. These returns do not
reflect sales loads and are not a guarantee of future performance.

INVESTMENT OBJECTIVE

     The Small Cap Fund seeks above-average, long-term capital appreciation in
order to provide investors with a rate of total return exceeding that of the
Russell 2000 Index, before fees and expenses, over a time horizon of three to
five years.

INVESTMENT POLICIES

     We actively manage a diversified portfolio of the common stock of growth-
oriented smaller companies. We define smaller companies as those whose market
capitalizations fall within the range of the Russell 2000 Index. As of July
1997, that range was between $171.1 million and $1.1billion. This range is
expected to change frequently and we may sometimes invest in companies whose
market capitalizations are smaller or larger than the range. We will, however,
sell the stock of companies whose market capitalization grow above $2 billion.

     We invest in the common stock of domestic and foreign companies we believe
have above-average prospects for capital growth,  and that are involved in new
or innovative products, services and processes.
 

PORTFOLIO HOLDINGS

Under normal market conditions, we invest:
 .   in an actively managed, broadly-diversified portfolio of growth-oriented
    common stocks;
 .   in at least 20 common stock issues spread across multiple industry groups
    and sectors of the economy;
 .   no more than 40% of our assets in initial public offerings or recent start-
    ups and newer issues;
 .   no more than 25% of our assets in foreign companies through American
    Depository Receipts or similar issues; and
 .   up to 15% of our portfolio in emerging markets;

     We may invest in preferred stock or investment-grade debt securities that
are convertible into common stock, and in money market instruments to maintain
liquidity, to meet expected redemption requests or as a temporary defensive
measure when we believe that the basic investment strategy is not in the best
interest of shareholders. Generally, these defensive investments are temporary
and will not exceed 35% of total assets.

IMPORTANT RISK FACTORS

Please see the general risks section beginning on page ____.

This Fund is designed for investors willing to assume above-average risk. We may
invest in companies that:
 .   pay low or no dividends;
 .   have smaller market capitalizations;
 .   have less market liquidity;
 
<PAGE>

                            Plain English Equity Prospectus (October 8, 1997) 15

 .   have no or relatively short operating histories, or are newly public
    companies or are initial public offerings;
 .   have aggressive capital structures including high debt levels; and
 .   are involved in rapidly growing or changing industries and/or new
    technologies.
Because we invest in such aggressive securities, share prices may rise and fall
more than the share prices of other funds. In addition, our active trading
investment strategy may result in higher-than-average portfolio turnover ratio,
increased trading expenses, and short-term capital gains.
 
ADDITIONAL FUND FACTS

We have an annual dividend policy. You should not invest in the Fund if you are
looking for monthly income.

GENERAL RISK CONSIDERATIONS

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your tolerance and preferences. Some
risks are common to all the Stagecoach Funds. Chief among these risks is the
following:

 .    Unlike bank deposits such as CD's or savings accounts, mutual funds are NOT
     INSURED BY THE FDIC.
 .    We CANNOT GUARANTEE that we will meet our investment objectives.
 .    We do not guarantee the performance of a Fund, nor can we assure you that
     the market value of your investment will not decline. We will not "make
     good" any investment loss you may suffer, nor can anyone we contract with
     to perform certain functions, such as selling agents or investment
     advisors, offer or promise to make good any such losses.
 .    Share prices--and therefore the value of your investment--WILL INCREASE AND
     DECREASE with changes in the value of the underlying securities and other
     investments. This is referred to as volatility.
 .    Investing in any mutual fund, including the most conservative, involves
     RISK, INCLUDING THE POSSIBLE LOSS OF ANY MONEY YOU INVEST.
 .    No single Fund, by itself, constitutes a complete investment plan.

Some of our mutual funds invest in securities that involve particular kinds of
risk.

 .    Funds that invest in equities are subject to EQUITY MARKET RISK, which is
     the risk that stock prices will fluctuate and can decline and reduce the
     value of the portfolio. Certain types of stock and certain stocks selected
     for a Fund's portfolio may underperform or decline in value more than the
     overall market. As of the date of this Prospectus, the equity market, as
     measured by the S&P 500 Index and other commonly used indexes, is trading
     at or close to record levels. There can be no guarantee that these
     performance levels will continue.
 .    Funds that invest in debt instruments, such as notes and bonds, are subject
     to CREDIT RISK and INTEREST-RATE RISK. Credit risk is the chance that an
     issuer of a security will be unable to make interest payments or repay
     principal. Changes in the financial strength of an issuer or changes in the
     credit rating of a security may affect its value. Interest-rate risk is the
     possibility that interest rates may increase and reduce the resale value of
     securities in a Fund's portfolio. Debt instruments with longer maturities
     are generally more sensitive to interest rate changes than those with
     shorter maturities. Changes in market interest rates do not affect the rate
     payable on debt instruments held in a Fund, unless the instrument has
     adjustable or variable rate features. Changes in market interest rates may
     also extend or shorten the duration of certain types of instruments, such
     as asset-backed securities, thereby affecting their value and the return on
     your investment.
 .    Funds that invest in SMALLER COMPANIES, FOREIGN COMPANIES (including
     investments made through American Depository Receipts and similar
     instruments), and in EMERGING MARKETS are subject to additional risks,
     including less liquidity and greater volatility. A Fund's investment in
     foreign and emerging markets may also be subject to special risks
     associated with international trade, including currency, political,
     regulatory and diplomatic risk.

We may invest a portion of our assets in U.S. Government obligations. It is
important to recognize that the U.S. Government does not guarantee the market
value or current yield of those obligations. Not all U.S. Government obligations
are backed by the full faith and credit of the U.S. Treasury, and the U.S.
Government's guarantee does not extend to the Fund itself.

We may also use certain DERIVATIVE instruments such as options or futures
contracts. The term "derivatives" covers a wide number of investments, but in
general it refers to any financial instrument whose value is derived, at least
in part, from the price of another security or a specified index, asset or rate.
Some derivatives may be more sensitive to interest rate changes or market moves,
and some may be susceptible to changes in yields or values due to their
structure or contract terms.

What follows is a general list of the types of risks that may affect a given
Fund and a table showing some of the additional investment practices that each
Fund may use. Additional information about these practices is available in the
Statement of Additional Information.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule. If an issuer does default, the
affected security could lose all of its value, or be renegotiated at a lower
interest rate. Affected securities might also lose liquidity.  Credit risk also
includes the risk that a party in a transaction may not be able to complete the
transaction as agreed.

Currency Risk--The risk that a change in the exchange rate between U.S. dollars
and a foreign currency may reduce the value of investment made in a security
denominated in that foreign currency.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value or
liquidity of investments in either country.

Experience Risk--The risk presented by a new or innovative security. The risk is
that insufficient experience exists to forecast how the security's value might
be affected by various economic conditions.

Information Risk--The risk that information about a security is either
unavailable, incomplete or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security. Generally, when interest rates increase, the value of a
debt security decreases. The effect is usually more pronounced for securities
with longer dates to maturity.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of stock, bond or other security will
reduced by market activity. This is the basic risk associated with all
securities investments.

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation's or region's industry,
government or markets.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security. Also the risk that an insufficiently regulated
market might permit inappropriate trading practices.

Investment practices and risk levels are carefully monitored. We attempt to
ensure that the risk exposure for each Fund remains within the parameters of its
objective.

The Investment Objectives described for each Fund are fundamental and cannot be
changed without approval by vote of a majority of shareholders.

In addition to the general risks discussed above, you should carefully consider
and evaluate any special risks that may apply to investing in a particular Fund.
See the "Important Risk Factors" in the summary for each Fund. You should also
see the Statements of Additional Information for additional discussion involving
risk and investment practices.

YOUR ACCOUNT

Minimum Investments:
 . $1,000,000.00 per Fund minimum initial investment;
 . $25,000.00 per Fund for all investments after the first;
 . Investors in certain various fiduciary accounts and certain other investors
  are not subject to minimum initial or subsequent investment amount
  requirements.

 . BUYING SHARES

You can buy Fund shares at Net Asset Value (NAV) through affiliate, franchise or
correspondent banks of Wells Fargo and other select institutions. Individual
investors interested in purchasing Institutional shares of the Funds should
contact an account representative at an institution and should understand the
following:
 . share purchases are made through your Customer Account at an institution and
  are executed and confirmed according to the terms of Customer Account
  involved;
 . institutions, acting on behalf of their customers, are usually holders of
  record of Institutional shares and maintain records reflecting their
  customers' beneficial ownership of the shares;
 . institutions are responsible for transmitting purchase orders by their
  customers and delivering required payment on a timely basis;
 . the exercise of voting rights and the delivery of shareholder communications
  from the Funds is governed by the customer's account agreement with the
  Institution;
 . institutions may charge their customers account fees and may receive fees from
  us with respect to investments their customers have made with the Funds.
  See "The Organization of the Funds" for further details about these fees.


Additional Important Information about Investing:

 . Read this prospectus carefully. Discuss any questions you have with your
  account representative. You may also ask for copies of the Statements of
  Additional Information. Copies are available free of charge from your
  account representative or by calling 1-800 260-5969.
 . We process requests to buy or sell shares every business day at the close of
  business on the New York Stock Exchange, usually at 1:00 PM Pacific Time. Any
  request we receive in proper form before the close of business is processed
  the same business day. Requests we receive after the close are processed the
  next business day.
 . It is the nature of a mutual fund investment that the price you pay to
  purchase shares or the price you receive when you redeem shares is not
  determined until after a request has been received in proper form.
 . We determine the Net Asset Value (NAV) of each class of the Fund's shares each
  business day as of the close of the New York Stock Exchange. We determine the
  NAV by subtracting the Fund class's liabilities from its total assets, and
  then dividing the result by the total number of outstanding shares of that
  class. See the Statements of Additional Information for further disclosure.
 . Your institution may require additional paperwork for certain types of account
  registrations, such as a Trust. Please speak to your account representative
  at the institution for details.

SELLING SHARES

Institutional shares held on behalf of an institution's customers must be
redeemed in accordance with the account agreement governing the customer's
account at the institution. Please read your account agreement with your
institution for rules governing selling shares. General Notes for Selling
Shares:
 . We will process redemption requests we receive in proper form before the close
  of the New York Stock Exchange, usually 1:00 P.M. Pacific Time, at the NAV
  determined on the same business day.
 . Redemption Proceeds are usually wired to the redeeming institution the
  following business day.
 
<PAGE>

                          Plain English Equity Prospectus (October 8, 1997) 22


 . We reserve the right to delay payment of redemption for up to ten days so that
  we may be reasonably certain that investments made by check have been
  collected. Payments of r edemptions may also be delayed under extraordinary
  circumstances or as permitted by the SEC in order to protect remaining
  shareholders. Payments of redemptions may also be delayed up to seven days
  under normal circumstances, although it is not our policy to delay such
  payments.
 . Generally, we pay redemption requests in cash, unless the redemption request
  is for more than $250,000 or 1% of the net assets of the Fund by a single
  shareholder over any ninety-day period. If a request for redemption is over
  these limits it may be to the detriment of existing shareholders. Therefore,
  we may pay the redemption in part or in whole in securities of equal value.

If you do not have a relationship with an Institution, you may redeem shares by
writing or calling us directly. Redemption proceeds in such cases are usually
sent by check unless a wire transfer is requested. We will act on instructions
that we reasonably believe to be genuine.

EXCHANGES

Exchanges between Stagecoach Funds are two transactions: a sale of one Fund and
the purchase of another. In general, the same rules and procedures that apply to
sales and purchases apply to exchanges. There are, however, additional factors
you should keep in mind while making or considering an exchange:
 . You will need to read the Prospectus for the Fund into which you wish to
  exchange.
 . Every exchange involves selling Fund shares and that sale may produce a
  capital gain or loss for federal income tax purposes.
 . If you are making an initial investment into a new Fund through an exchange,
  you must exchange at least the minimum first purchase amount of the Fund
  you are redeeming, unless your balance has fallen below that amount due to
  market conditions.
 . Any exchange between Funds you already own must meet the minimum redemption
  and subsequent purchase amounts for the Funds involved.
 . In order to discourage market timing and excessive transaction expenses that
  must be borne by other shareholders, we reserve the right to limit or
  reject exchange orders. Generally, we will notify you 60 days in advance of
  any changes in your exchange privileges.

WIRE PURCHASE INSTRUCTIONS FOR INSTITUTIONS:

ADDITIONAL SERVICES AND POLICIES

DIVIDEND AND CAPITAL GAIN DISTRIBUTION OPTIONS

You may choose to do any of the following:
 . AUTOMATIC REINVESTMENT OPTION - Lets you buy new shares of the same class of
  the Fund that generated the distributions. The new shares are purchased at
  NAV generally on the day the income is paid. This option is automatically
  assigned to your account unless you specify another plan.
 . FUND PURCHASE PLAN - Uses your distributions to buy shares at NAV of another
  Stagecoach Fund of the same share class or a Money Market Fund. You must
  have already satisfied the minimum investment requirements of the Fund into
  which your distributions are being transferred in order to participate.
 . AUTOMATIC CLEARING-HOUSE OPTION - Deposits your dividends and capital gains
  into any bank account you link to your Fund account if it is part of the
  ACH system. If your specified bank account is closed, we will reinvest your
  distributions.
 . CHECK PAYMENT OPTION - Allows you to receive checks for distributions mailed
  to your address of record or to another name and address which you have
  specified in written, signature guaranteed instructions. If checks remain
  uncashed for six months or are undeliverable by the Post Office, we will
  reinvest the distributions at the earliest date possible.

Call Out -  "Two Things to Keep In Mind About Distributions" - Remember,
distributions have the effect of reducing the NAV per share by the amount
distributed. Also, distributions on new shares shortly after purchase would be
in effect a return of capital, although the distribution may still be taxable to
you.

TAXES

We will pass on to you net investment income and net short-term capital gains
earned by a Fund as dividend distributions. These are taxable to you as ordinary
income. Corporate shareholders may be able to exclude a portion of dividend
income from their taxable income.

Long-term capital gains earned by a Fund will be passed on to you as capital
gains and will be taxable to you as long-term capital gains. In general,
distributions are taxable when paid. However, distributions declared in October,
November and December and distributed by the following January will be taxable
as if they were paid on December 31.

Your redemptions will ordinarily result in a taxable capital gain or loss,
depending on the amount you receive for your shares and the amount you paid for
them. Foreign shareholders may be subject to different tax treatment, including
withholding. In certain circumstances, U.S. residents may also be subject to tax
withholding.

Additional details about the tax consequences of investing are available to you
in the Statements of Additional Information. The discussion of taxes is only a
summary based on laws in effect as of the date of this Prospectus and is not a
substitute for careful tax planning

Fund of the Stagecoach Funds, Inc. For accounting purposes, the Overland Express

offer Class B shares, therefore no Class B shares are shown in the Financial
Highlights.

Share Class: This prospectus contains information about Institutional shares.
Some of the Funds may offer additional share classes with different expenses and
returns than those described here. Call Stephens Inc. at 1-800-643-9691 for
information on these or other investment options in the Funds.

Minimum Account Value - Due to the expense involved in maintaining low-balance
accounts, we reserve the right to close accounts that have fallen below the
$1,000,000.00 minimum balance due to redemptions (as opposed to market
conditions). You will be given an opportunity to make additional investments to
prevent account closure before any action is taken.

Statements - Institutions or their nominees typically send their investors a
confirmation or statement of account after every transaction that affects their
share balance. We will send any necessary tax reporting documents in January,
and will send Annual and Semi-Annual Reports each year.

Statements of Additional Information- Additional information about some of the
topics discussed in This Prospectus as well as details about return
calculations, distribution plans, servicing plans, tax issues and other
important issues are available in the Statement of Additional Information for
each Fund. The Statement of Additional Information should be read along with
this Prospectus and may be obtained free of charge by calling Investor Services
at 1 800-222-8222.

Glass-Steagall Act - Morrison & Foerster LLP, counsel to the Funds and special
counsel to Wells Fargo Bank, has advised us and Wells Fargo Bank that Wells
Fargo Bank and its affiliates may perform the services contemplated by the
Advisory Contracts and detailed in this Prospectus and the Statements of
Additional Information without violation of the Glass-Steagall Act. Counsel has
pointed out that future judicial or administrative decisions, or future federal
or state laws may prevent these entities from continuing in their roles.

Voting Rights--All shares of the Funds have equal voting rights and are voted in
the aggregate, rather than by series or class, unless the matter affects only
one series or class. A Fund's shareholder of record is entitled to one vote for
each share owned and fractional votes for each fractional share owned. For a
detailed description of voting rights, see the "Capital Stock" section of the
SAI.

HOW TO READ THE FINANCIAL HIGHLIGHTS

After each Fund's Investment Objective and Investment Policies, charts are
provided showing important financial information about Fund. The charts are
called "Financial Highlights" and are designed to help you understand the past
performance of each Fund. The financial statements, from which these Financial
Highlights were derived, were audited by KPMG Peat Marwick LLP except as
indicated. The financial statements are available in the Fund's most recent
Annual Report and are available free of charge by calling 1-800-222-8222. The
statements were audited by KPMG Peat Marwick LLP. Other auditors audited
statements for the Intermediate Bond Fund for periods prior to October 1, 1995
and for the Growth and Income Fund prior to January 1, 1992.  Here is an
explanation of some terms that will help you interpret these charts.

NET ASSET VALUE (NAV)--The value of one share of a class of a Fund, excluding
any sales charge. See the Glossary for a fuller definition.

NET INVESTMENT INCOME--When we receive dividend or interest payments from an
investment or earn trading profits, we deduct management fees, administrative
and other expenses and then record the result as net investment income. The
number in the financial highlights is the net investment income of a class
divided by the number of outstanding shares of that class. The amount
distributed to shareholders is listed under the heading "Less Distributions-
Dividends from Net Investment Income."

NET REALIZED AND UNREALIZED CAPITAL GAINS--We buy and sell investments
frequently. The profit on an investment sold for more than its purchase price is
a realized capital gain while any loss is a realized capital loss. An unrealized
gain or loss occurs when an investment gains or loses value but is not sold. The
number in this category is the total gains or losses of a class divided by the
number of outstanding fund shares for that class. The amount of capital gain or
loss per share that was passed on to shareholders is listed under the heading
"Less Distributions-Distributions From Net Realized Gains."

NET ASSETS--The value of the investments in a Fund's portfolio that are
attributable to a particular class of the Fund.

RATIO OF EXPENSES TO AVERAGE NET ASSETS--This ratio reflects the amount paid by
a Fund to cover the costs of its daily operations, and includes advisory,
administrative and other operating expenses. It is expressed as a percentage of
the average daily net assets of a class.

U.S. Government Income Fund

Portfolio Managers:   Tamyra Thomas (since 7/96)
- -------------------                             
                      Paul Single (since 5/95)


INVESTMENT OBJECTIVE

          The U.S. Government Income Fund seeks a long-term total rate of return
through preserving capital and earning high interest income by investing
principally in a portfolio of U.S. Government mortgage pass-through securities,
consisting primarily of securities issued by GNMA, FNMA and FHLMC.

INVESTMENT POLICIES

          We actively manage a diversified portfolio of U.S. Government mortgage
pass-through securities (including those issued by GNMA, FNMA and FHLMC), U.S.
Treasury securities and repurchase agreements.

PORTFOLIO HOLDINGS

Under normal market conditions, we invest:
 .    at least 65% of our total assets in mortgage pass-through securities; and
 .    in Treasury securities and repurchase agreements collateralized by U.S.
     Government obligations.

          We may temporarily hold assets in cash or in money market instruments,
including U.S. Government obligations, shares of other mutual funds and
repurchase agreements, or make other short-term investments, either to maintain
liquidity or for short-term defensive purposes when we believe it is in the best
interest of shareholders to do so.

RISK FACTORS

For general information on risk, please see page ___.

The United States Government guarantees the timely payment of interest and
principal of GNMA and Treasury securities with its full faith and credit. FNMA
and FHLMC securities, however, are guaranteed by the issuing agencies and not by
the U.S. Government. There is no guarantee that the U.S. Government will support
FNMA and FHLMC securities if they are unable to meet their obligations. The U.S.
Government does not directly or indirectly insure or guarantee the performance
of the Fund.  Mortgage-backed securities are subject to the risk that homeowners
may refinance existing mortgages to take advantage of lower rates. Such
"prepayments" result in an early return of principal that is then reinvested at
what is likely to be a lower yield.

ADDITIONAL FUND FACTS

There are no Financial Highlights for the Fund. See page ___ for Historical Fund
information.

Mortgage pass-through securities are residential home mortgages bundled together
and sold as a single security. Mortgage payments are "passed through" the
issuing agency to the security's holder as interest and principal payments. GNMA
securities are commonly known as "Ginnie Maes," FNMA as "Fannie Maes" and FHLMC
as "Freddie Mac".

Intermediate Bond Fund

Portfolio Managers:  Scott Smith (since 9/96)
- -------------------                          
                     Tamyra Thomas (since 9/96)

          The Intermediate Bond Fund seeks to provide investors with a high
level of current income consistent with the preservation of capital and the
maintenance of liquidity.

INVESTMENT POLICIES

          We actively manage a broad range of corporate debt, U.S. Government
obligations and other debt securities and instruments. When deciding the
allocation between corporate and U.S. Government debt, we consider the
differences between the yields for corporate and government bonds, as well as
the yield differences for various corporate sectors, and the current economic
cycle's likely effect on the various types of bonds. When buying individual
securities, we consider credit-quality and the security's attractiveness.  The
portfolio is diversified.
          Under normal market conditions, we will maintain a dollar-weighted
average portfolio maturity of between 3 and 10 years.
 
PORTFOLIO HOLDINGS

Under normal market conditions, the Fund will invest:
 .    at least 65% of our total assets in corporate and government bonds;
 .    no more than 20% of total assets in the dollar-denominated debt of foreign
     issuers; and
 .    in zero-coupon bonds, repurchase agreements, municipal bonds, and
     obligations convertible into common stock.

See the table on page ___ in the "Risk and Additional Policies" section for
other acceptable investments.

          The debt obligations we buy for the portfolio generally will be rated
"BBB" (S&P) or "Baa" (Moody's) or better. We may also invest in unrated debt
obligations that we feel are of comparable quality. The dollar-weighted average
credit quality of the corporate bonds will be "A" or better. We may temporarily
hold assets in cash or in money market instruments, including U.S. Government
obligations, shares of other mutual funds and repurchase agreements, or make
other short-term investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interest of shareholders to
do so.

RISK FACTORS

For general information on risk, please see page ___.

ADDITIONAL FUND FACTS

          As a general matter, we will not invest in common stocks. Common stock
received through the conversion of convertible securities will be sold as soon
as possible in an orderly manner.

Short-Intermediate U.S. Government Income Fund

Portfolio Managers:  Jeff Weaver (since 7/96)
- -------------------                          
                     Madeleine Gish (since 7/96)

INVESTMENT OBJECTIVE

          The Short-Intermediate U.S. Government Income Fund seeks to provide
investors with current income while preserving capital, by investing primarily
in a portfolio consisting of short- to intermediate term securities issued or
guaranteed by the U.S. Government, its agencies and instrumentalities.

INVESTMENT POLICIES

          We seek current income by actively managing a diversified portfolio
consisting primarily of short-to intermediate-term U.S. Government obligations.
We may invest in securities of any maturity. Under ordinary circumstances, we
expect to maintain a dollar-weighted effective average maturity of between 2 and
5 years. We seek to preserve capital by shortening average maturity when
interest rates are expected to increase and to increase total return by
lengthening maturity when interest rates are expected to fall.

PORTFOLIO HOLDINGS
 
Under normal market conditions, we invest:
 .    at least 65% of our total assets in U.S. Government obligations;
 .    in investment grade corporate debt securities including asset-backed
     securities;
 .    in repurchase agreements;
 .    no more than 5% of our total assets in securities downgraded below
     investment grade after we acquired them;
 .    up to 25% of our assets in dollar-denominated debt of U.S. branches of
     foreign banks or foreign branches of U.S. banks; and
 .    in Stripped Treasury securities, adjustable-rate mortgage securities,
     adjustable portions of collateralized mortgage obligations.

          We may temporarily hold assets in cash or in money market instruments,
including U.S. Government obligations, shares of other mutual funds and
repurchase agreements, or make other short-term investments, either to maintain
liquidity or for short-term defensive purposes when we believe it is in the best
interest of shareholders to do so.


IMPORTANT RISK FACTORS

For general information on risk, please see page ______.

Stripped Treasury securities have greater interest rate risk than traditional
government securities with identical credit ratings. The U.S. Government does
not directly or indirectly insures or guarantees the performance of the Fund.

GENERAL RISK CONSIDERATIONS

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your tolerance and preferences. Some
risks are common to all the Stagecoach Funds. Chief among these risks is the
following:

 .    Unlike bank deposits, such as CD's or savings accounts, mutual funds are
     NOT INSURED BY THE FDIC.
 .    We CANNOT GUARANTEE that we will meet our investment objectives.
 .    We do not guarantee the performance of a Fund, nor can we assure you that
     the market value of your investment will not decline. We will not "make
     good" any investment loss you may suffer, nor can anyone we contract with
     to perform certain functions, such as selling agents or investment
     advisors, offer or promise to make good any such losses.
 .    Share prices--and therefore the value of your investment--WILL INCREASE AND
     DECREASE with changes in the value of the underlying securities and other
     investments. This is referred to as volatility.
 .    Investing in any mutual fund, including the most conservative, involves
     RISK, INCLUDING THE POSSIBLE LOSS OF ANY MONEY YOU INVEST.
 .    No single Fund, by itself, constitutes a complete investment plan.

Some of our mutual funds invest in securities that involve particular kinds of
risk;

 .    Funds that invest in debt instruments, such as notes and bonds, are subject
     to CREDIT RISK. Credit risk is the chance that an issuer of a security will
     be unable to make interest payments or repay principal. Changes in the
     financial strength of an issuer or changes in the credit rating of a
     security may affect its value.
 .    Funds that invest in debt instruments, such as notes and bonds, are subject
     to INTEREST-RATE RISK. Interest-rate risk is the possibility that interest
     rates may increase and reduce the resale value of securities in a Fund's
     portfolio. Debt instruments with longer maturities are generally more
     sensitive to interest rate changes than those with shorter maturities.
     Changes in market interest rates do not affect the rate payable on debt
     instruments held in a Fund, unless the instrument has adjustable or
     variable rate features. Changes in market interest rates may also extend or
     shorten the duration of certain types of instruments, such as asset-backed
     securities, thereby affecting their value and the return on your
     investment.

We may invest a portion of our assets in U.S. Government obligations. It is
important to recognize that the U.S. Government does not guarantee the market
value or current yield of those obligations. Not all U.S. Government obligations
are backed by the full faith and credit of the U.S. Treasury, and the U.S.
Government's guarantee does not extend to the Fund itself.

We also invest a portion of our assets in GNMAs, FNMAs and FHLMCs. Each are
mortgage-backed securities representing partail ownership of a pool of
residential mortgage loans. A "pool" or group of such mortgages is assembled
and, after being approved by the entity, is offered to investors through
securities dealers. Once approved by GNMA, a government corporation within the
U.S. Department of Housing and Urban Development, the timely payment of interest
and principal of a GNMA security is guaranteed by the full faith and credit of
the U.S. Government. FNMA and FHLMC are federally chartered corporations
supervised by the U.S. Government, acting as government-sponsored enterprises.
FNMA and FHLMC securities are not direct obligations of the U.S. Treasury, and
are supported by the credit of FNMA or FHLMC only. FNMA guarantees timely
payment of interest and principal on its securities; FHLMC guarantees timely
payment of interest and ultimate payment of principal only.

We may also use certain DERIVATIVE instruments such as options or futures
contracts. The term "derivatives" covers a wide number of investments, but in
general it refers to any financial instrument whose value is derived, at least
in part, from the price of another security or a specified index, asset or rate.
Some derivatives may be more sensitive to interest rate changes or market moves,
and some may be susceptible to changes in yields or values due to their
structure or contract terms.

What follows is a general list of the types of risks that may affect a given
Fund and a table showing some of the additional investment practices that each
Fund may use. Additional information about these practices is available in the
Statement of Additional Information.

Counter-party Risk--The risk that the other party in a repurchase agreement or
other transactions will not fulfill its contract obligation.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule. If an issuer does default, the
affected security could lose all of its value, or be renegotiated at a lower
interest rate. Affected securities might also lose liquidity.  Credit risk also
includes the risk that a party in a transaction may not be able to complete the
transaction as agreed

Currency Risk--The risk that a change in the exchange rate between U.S. dollars
and a foreign currency may reduce the value of investment made in a security
denominated in that foreign currency.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value or
liquidity of investments in either country.

Experience Risk--The risk presented by a new or innovative security. The risk is
that insufficient experience exists to forecast how the security's value might
be affected by various economic conditions.

Extension Risk--The risk that as interest rates rise, prepayments slow, thereby
lengthening the duration and potentially reducing the value of certain asset-
backed securities.

Information Risk--The risk that information about a security is either
unavailable or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security. Generally, when interest rates increase, the value of a
debt security decreases. The effect is usually more pronounced for securities
with longer dates to maturity.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of stock, bond or other security will be
reduced by market activity. This is the basic risk associated with all
securities investments.

Prepayment Risk--The risk that, as interest rates fall, homeowners will
refinance existing mortgages, causing mortgage-backed securities to have reduced
yields.

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation's or region's industry,
government or markets.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security. Also the risk that an insufficiently regulated
market might permit inappropriate trading practices.

               Institutional Income Funds Prospectus (November 3, 1997, 1997) 14


Investment practices and risk levels are carefully monitored. We attempt to
ensure that the risk exposure for each Fund remains within the parameters of its
objective.

The Investment Objectives described for the U.S. Government Income, Intermediate
Bond and Short-Intermediate US Government Income Funds are not fundamental and
may be changed without approval by vote of a majority of shareholders. The
Investment Objectives described for the Short-Term Government-Corporate and
Variable Rate Government Funds are fundamental and cannot be changed without
approval by vote of a majority of shareholders.

In addition to the general risks discussed above, you should carefully consider
and evaluate any special risks that may apply to investing in a particular Fund.
See the "Important Risk Factors" in the summary for each Fund. You should also
see the Statements of Additional Information for additional discussion involving
risk and investment practices.

               Institutional Income Funds Prospectus (November 3, 1997, 1997) 15


YOUR ACCOUNT

Minimum Investments:
 .    $1,000,000.00 per Fund minimum initial investment;
 .    $25,000.00 per Fund for all investments after the first;
 .    Investors in certain various fiduciary accounts and certain other investors
     are not subject to minimum initial or subsequent investment amount
     requirements.

BUYING SHARES

You can buy Fund shares at Net Asset Value (NAV) through affiliate, franchise or
correspondent banks of Wells Fargo and other select institutions. Individual
investors interested in purchasing Institutional shares of the Funds should
contact an account representative at an institution and should understand the
following:
 .    share purchases are made through your Customer Account at an institution
     and are executed and confirmed according to the terms of Customer Account
     involved;
 .    institutions, acting on behalf of their customers, are usually holders of
     record of Institutional shares and maintain records reflecting their
     customers' beneficial ownership of the shares;
 .    institutions are responsible for transmitting purchase orders by their
     customers and delivering required payment on a timely basis;
 .    the exercise of voting rights and the delivery of shareholder
     communications from the Funds is governed by the customer's account
     agreement with the Institution;
 .    institutions may charge their customers account fees and may receive fees
     from us with respect to investments their customers have made with the
     Funds. See "The Organization of the Funds" for further details about these
     fees.


Additional Important Information about Investing:

 .    Read this prospectus carefully. Discuss any questions you have with your
     account representative. You may also ask for copies of the Statements of
     Additional Information. Copies are available free of charge from your
     account representative or by calling 1-800 260-5969.
 .    We process requests to buy or sell shares every business day at the close
     of business on the New York Stock Exchange, usually at 1:00 PM Pacific
     Time. Any request we receive in proper form before the close of business is
     processed the same business day. Requests we receive after the close are
     processed the next business day.
 .    It is the nature of a mutual fund investment that the price you pay to
     purchase shares or the price you receive when you redeem shares is not
     determined until after a request has been received in proper form.
 .    We determine the Net Asset Value (NAV) of each class of the Fund's shares
     each business day as of the close of the New York Stock Exchange. We
     determine the NAV by subtracting the Fund class's liabilities from its
     total assets, and then dividing the result by the total number of
     outstanding shares of that class. See the Statements of Additional
     Information for further disclosure.
 .    Your institution may require additional paperwork for certain types of
     account registrations, such as a Trust. Please speak to your account
     representative at the institution for details.


SELLING SHARES

Institutional shares held on behalf of an institution's customers must be
redeemed in accordance with the account agreement governing the customer's
account at the institution. Please read your account agreement with your
institution for rules governing selling shares. General Notes for Selling
Shares:
 .    We will process redemption requests we receive in proper form before the
     close of the New York Stock Exchange, usually 1:00 P.M. Pacific Time, at
     the NAV determined on the same business day.
 .    Redemption Proceeds are usually wired to the redeeming institution the
     following business day.
<PAGE>
 
               Institutional Income Funds Prospectus (November 3, 1997, 1997) 16


 .    We reserve the right to delay payment of redemption for up to ten days so
     that we may be reasonably certain that investments made by check have been
     collected. Payments of redemptions may also be delayed under extraordinary
     circumstances or as permitted by the SEC in order to protect remaining
     shareholders. Payments of redemptions may also be delayed up to seven days
     under normal circumstances, although it is not our policy to delay such
     payments.
 .    Generally, we pay redemption requests in cash, unless the redemption
     request is for more than $250,000 or 1% of the net assets of the Fund by a
     single shareholder over any ninety-day period. If a request for redemption
     is over these limits it may be to the detriment of existing shareholders.
     Therefore, we may pay the redemption in part or in whole in securities of
     equal value.

If you do not have a relationship with an Institution, you may redeem shares by
writing or calling us directly. Redemption proceeds in such cases are usually
sent by check unless a wire transfer is requested. We will act on instructions
that we reasonably believe to be genuine.

EXCHANGES

Exchanges between Stagecoach Funds are two transactions: a sale of one Fund and
the purchase of another. In general, the same rules and procedures that apply to
sales and purchases apply to exchanges. There are, however, additional factors
you should keep in mind while making or considering an exchange:
 .    You will need to read the Prospectus for the Fund into which you wish to
     exchange.
 .    Every exchange involves selling Fund shares and that sale may produce a
     capital gain or loss for federal income tax purposes.
 .    If you are making an initial investment into a new Fund through an
     exchange, you must exchange at least the minimum first purchase amount of
     the Fund you are redeeming, unless your balance has fallen below that
     amount due to market conditions.
 .    Any exchange between Funds you already own must meet the minimum redemption
     and subsequent purchase amounts for the Funds involved.
 .    In order to discourage market timing and excessive transaction expenses
     that must be borne by other shareholders, we reserve the right to limit or
     reject exchange orders. Generally, we will notify you 60 days in advance of
     any changes in your exchange privileges.

ADDITIONAL SERVICES AND POLICIES

DIVIDEND AND CAPITAL GAIN DISTRIBUTION OPTIONS

You may choose to do any of the following:

 .    AUTOMATIC REINVESTMENT OPTION - Lets you buy new shares of the same class
     of the Fund that generated the distributions. The new shares are purchased
     at NAV generally on the day the income is paid. This option is
     automatically assigned to your account unless you specify another plan.
 .    FUND PURCHASE PLAN - Uses your distributions to buy shares at NAV of
     another Stagecoach Fund of the same share class or a Money Market Fund. You
     must have already satisfied the minimum investment requirements of the Fund
     into which your distributions are being transferred in order to
     participate.
 .    AUTOMATIC CLEARING-HOUSE OPTION - Deposits your dividends and capital gains
     into any bank account you link to your Fund account if it is part of the
     ACH system. If your specified bank account is closed, we will reinvest your
     distributions.
 .    CHECK PAYMENT OPTION - Allows you to receive checks for distributions
     mailed to your address of record or to another name and address which you
     have specified in written, signature guaranteed instructions. If checks
     remain uncashed for six months or are undeliverable by the Post Office, we
     will reinvest the distributions at the earliest date possible.

Call Out -  "Two Things to Keep In Mind About Distributions" - Remember,
distributions have the effect of reducing the NAV per share by the amount
distributed. Also, distributions on new shares shortly after purchase would be
in effect a return of capital, although the distribution may still be taxable to
you.

TAXES

We will pass on to you net investment income and net short-term capital gains
earned by a Fund as dividend distributions. These are taxable to you as ordinary
income. Corporate shareholders may be able to exclude a portion of dividend
income from their taxable income.

Long-term capital gains earned by a Fund will be passed on to you as capital
gains and will be taxable to you as long-term capital gains. In general,
distributions are taxable when paid. However, distributions declared in October,
November and December and distributed by the following January will be taxable
as if they were paid on December 31.

Your redemptions will ordinarily result in a taxable capital gain or loss,
depending on the amount you receive for your shares and the amount you paid for
them. Foreign shareholders may be subject to different tax treatment, including
withholding. In certain circumstances, U.S. residents may also be subject to tax
withholding.

Additional details about the tax consequences of investing are available to you
in the Statements of Additional Information. The discussion of taxes is only a
summary based on laws in effect as of the date of this Prospectus and is not a
substitute for careful tax planning.

SPECIAL NOTICES:

HISTORICAL INFORMATION--
Intermediate Bond Fund-- The Fund operated as the Bonds Plus Fund of Westcore
Trust and was advised by First Interstate Bank of Oregon, N.A. from its
commencement of operations on June 1, 1988, until its reorganization as a
portfolio of Pacifica Funds Trust on October 1, 1995, when First Interstate
Capital Management, Inc. ("FICM") assumed investment advisory responsibilities.
In connection with the reorganization, existing Institutional shares were
converted into Investor shares of the Pacifica Fund which was reorganized as a
series of the Company on September 6, 1996. In connection with the second
reorganization, existing Investor shares were converted into Class A shares of
the Fund. In connection with 
<PAGE>
 
               Institutional Income Funds Prospectus (November 3, 1997, 1997) 19


the merger of First Interstate Bancorp into Wells Fargo & Company on April 1,
1996, FICM was renamed Wells Fargo Investment Management, Inc.

U.S. Government Income Fund--On December 12, 1997, the Overland Express U.S.
Government Income Fund was reorganized as the U.S. Government Income Fund of the
Stagecoach Funds, Inc. For accounting purposes, the Overland Express Fund is
considered the surviving entity and the financial highlights shown are for the
Class A and D shares of the Overland Fund. The Overland Fund did not offer Class
B shares, therefore no Class B shares are shown in the Financial Highlights.

Share Class: This prospectus contains information about Institutional shares.
Some of the Funds may offer additional share classes with different expenses and
returns than those described here. Call Stephens Inc. at 1-800-643-9691 for
information on these or other investment options in the Funds.

Minimum Account Value - Due to the expense involved in maintaining low-balance
accounts, we reserve the right to close accounts that have fallen below the
$1,000,000.00 minimum balance due to redemptions (as opposed to market
conditions). You will be given an opportunity to make additional investments to
prevent account closure before any action is taken.

Statements - Institutions or their nominees typically send their investors a
confirmation or statement of account after every transaction that affects their
share balance. We will send any necessary tax reporting documents in January,
and will send Annual and Semi-Annual Reports each year.

Statements of Additional Information- Additional information about some of the
topics discussed in this Prospectus as well as details about return
calculations, distribution plans, servicing plans, tax issues and other
important issues are available in the Statement of Additional Information for
each Fund. The Statement of Additional Information should be read along with
this Prospectus and may be obtained free of charge by calling Investor Services
at 1 800-222-8222.

Glass-Steagall Act - Morrison & Foerster LLP, counsel to the Funds and special
counsel to Wells Fargo Bank, has advised us and Wells Fargo Bank that Wells
Fargo Bank and its affiliates may perform the services contemplated by the
Advisory Contracts and detailed in this Prospectus and the Statements of
Additional Information without violation of the Glass-Steagall Act. Counsel has
pointed out that future judicial or administrative decisions, or future federal
or state laws may prevent these entities from continuing in their roles.

Voting Rights--All shares of the Funds have equal voting rights and are voted in
the aggregate, rather than by series or class, unless the matter affects only
one series or class. A Fund's shareholder of record is entitled to one vote for
each share owned and fractional votes for each fractional share owned. For a
detailed description of voting rights, see the "Capital Stock" section of the
SAI.

ABOUT STAGECOACH

The Fund is one of 32 of the Stagecoach Family of Funds.  Stagecoach was

may make a change in one of these companies.

meetings to ask shareholders to vote on items such as electing or removing board
members, amending fundamental investment strategies or policies or considering,
where applicable, matters affecting a Master Portfolio.

HOW TO READ THE FINANCIAL HIGHLIGHTS

After each Fund's Investment Objective and Investment Policies, charts are
provided showing important financial information about Fund. The charts are
called "Financial Highlights" and are designed to help you understand the past
performance of each Fund. The financial statements, from which these Financial
Highlights were derived, were audited by KPMG Peat Marwick LLP except as
indicated. The financial statements are available in the Fund's most recent
Annual Report and are available free of charge by calling 1-800-222-8222. Here
is an explanation of some terms that will help you interpret these charts.

NET ASSET VALUE (NAV)--The value of one share of a class of a Fund, excluding
any sales charge. See the Glossary for a fuller definition.

NET INVESTMENT INCOME--When we receive dividend or interest payments from an
investment or earn trading profits, we deduct management fees, administrative
and other expenses and then record the result as net investment income. The
number in the financial highlights is the net investment income of a class
divided by the number of outstanding shares of that class. The amount
distributed to shareholders is listed under the heading "Less Distributions-
Dividends from Net Investment Income."

NET REALIZED AND UNREALIZED CAPITAL GAINS--We buy and sell investments
frequently. The profit on an investment sold for more than its purchase price is
a realized capital gain while any loss is a realized capital loss. An unrealized
gain or loss occurs when an investment gains or loses value but is not sold. The
number in this category is the total gains or losses of a class divided by the
number of outstanding fund shares for that class. The amount of capital gain or
loss per share that was passed on to shareholders is listed under the heading
"Less Distributions-Distributions From Net Realized Gains."

NET ASSETS--The value of the investments in a Fund's portfolio that are
attributable to a particular class of the Fund.

RATIO OF EXPENSES TO AVERAGE NET ASSETS--This ratio reflects the amount paid by
a Fund to cover the costs of its daily operations, and includes advisory,
administrative and other operating expenses. It is expressed as a percentage of
the average daily net assets of a class.

RATIO OF NET INVESTMENT INCOME (LOSS) TO AVERAGE NET ASSETS--This ratio is the
result of dividing net investment income (or loss) by average net assets.

PORTFOLIO TURNOVER--Portfolio turnover is expressed as a percentage of a Fund's
investment portfolio and reflects the trading activity in the portfolio. For
example, a Fund with a 50% portfolio turnover has sold and bought half of its
investment portfolio during the given period.

will pay directly or indirectly as a shareholder in a Fund. It does not reflect
any charges that may be imposed by Wells Fargo Bank or other institutions in

Overland Express Sweep Fund

INVESTMENT OBJECTIVE

     The Overland Express Sweep Fund seeks to provide investors with a high
level of current income, while preserving capital and liquidity.

INVESTMENT POLICIES

     We actively manage a diversified portfolio of U.S. dollar-denominated, high
quality money market instruments, including debt obligations with remaining
maturities of 397 days or less. We maintain an overall dollar-weighted average
maturity of 90 days or less. We may also make certain other investment
including, for example, repurchase agreements. We seek to reduce risk by
investing assets in securities of various issuers and emphasize safety of
principal and high credit quality.

PORTFOLIO HOLDINGS

Under normal market conditions, we invest in:
 . U.S. Government obligations;
 . Obligations of domestic and foreign banks;
 . commercial paper;
 . repurchase agreements;
 . certain floating and variable- rate instruments;
 . certain U.S. dollar-denominated debt of U.S. branches of foreign banks; and
 . shares of other mutual funds.

IMPORTANT RISK FACTORS

For general information on risk, please see page ___.

We do not invest in certain types of derivative securities we consider volatile.
Among the investments not permitted are capped floaters, leveraged floaters,
range floaters, dual index floaters and inverse floaters.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value. Fluctuations in share value may cause a loss or gain in principal.
Generally, short-term funds do not earn as high a level of income as funds that
invest in longer-term instruments.  No government agency either directly or
indirectly insures or guarantees the performance of the Fund.

ADDITIONAL FUND FACTS

The Overland Express Sweep Fund is offered exclusively to customers of financial
institutions that have entered into a shareholder servicing agreement on behalf

GENERAL RISK CONSIDERATIONS

You should carefully consider risks common to all mutual funds. Chief among
these risks is the following:

 .    Unlike bank deposits, such as CD's or savings accounts, mutual funds
     are NOT INSURED BY THE FDIC.
 .    We CANNOT GUARANTEE that any Fund will meet its investment objectives.
     In particular, we can not guarantee that we will be able to maintain
     a $1.00 per share net asset value.
 .    You cannot recover through insurance any loss due to INVESTMENT
     PRACTICES, nor can the Fund, the selling agents or investment
     advisors make good any loss you might have.
 .    Investing in any mutual fund, including those deemed conservative,
     involve RISK, INCLUDING THE POSSIBLE LOSS OF ANY MONEY YOU INVEST.

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your tolerance and preferences. Some
mutual funds invest in assets that involve particular kinds of risk.

 .    Funds that invest in debt instruments, such as notes and bonds, are
     subject to CREDIT RISK and INTEREST-RATE RISK. Credit risk is the
     possibility that an issuer of a security will be unable to make interest
     payments or repay principal. Interest-rate risk is the possibility that
     interest rates may increase and reduce the resale value of lower-paying
     securities in the Fund's portfolio. Debt instruments with longer maturities
     are generally more sensitive to interest rate changes than those with
     shorter maturities. Interest rate risk does not affect the interest paid by
     a debt instrument unless it is specifically designed to pay an adjustable
     rate.

The Fund's advisor may also use certain DERIVATIVE instruments such as options
or futures contracts. The term "derivatives" covers a wide number of investment
practices but in general it refers to a financial instrument whose value is
derived, at least in part, from the price of another security or a specified
index, asset or rate. Some derivatives may be more sensitive to interest rate
changes or market moves, and some may be susceptible to changes in yields or
values due to the structure of their contracts.

The following types of floating-rate derivative securities are not
permitted investments in the Funds:

 .    Capped floaters on which interest is not paid when market rates move
     above a certain level;
 .    Leveraged floaters whose interest rates reset based on a formula that
     magnifies changes in market interest rates;
 .    Range floaters on which interest is not paid in market interest rates
     move outside a specified range;
 .    Dual index floaters whose interest rate reset provisions are tied to
     more than one index; and
 .    Inverse floaters which reset in an opposite direction of their index.

Investment practices and risk levels are carefully monitored. Every attempt is
made to ensure that the risk exposure for each Fund remains within the
parameters of its objective.

What follows is a general list of the types of risks that may affect a given
Fund and a table showing some of the additional investment practices that each
Fund may use. Additional information about these practices is available in the
Statement of Additional Information.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule. If an issuer does default, the
affected security could lose all of its value, or be renegotiated at a lower
interest rate. Affected securities might also lose liquidity. Credit risk
includes the risk that a party in a transaction may not be able to complete the
transaction as agreed.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value or
liquidity of investments in either country.

                          Overland Express Sweep Prospectus (October 27, 1997)-9

Information Risk--The risk that information about a security is either
unavailable or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security. Generally, when interest rates increase, the value of a
debt security decreases. The effect is usually more pronounced for securities
with longer dates to maturity.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of stock, bond or other security will
reduced by market activity. This is the basic risk associated with all
securities investments.

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation or region's industry,
government or markets.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security.

 .    Exclusively through a Servicing Agent who has entered into an agreement
     with us to make investments into the Fund on your behalf.


Important Information:
 .    The Servicing Agent buys and sells shares an your behalf. The Servicing
     Agent maintains an account with us in its name on your behalf.
 .    Your account agreement with the your Servicing Agent describes the
     procedures and regulations governing transactions.

     your financial consultant or by calling 1-800 222-8222.
 .    We process requests to buy or sell shares each business day at 9:00 AM,
     Pacific Time. Any request we receive in proper form before 9:00 AM PT is
     processed the same day. Requests we receive after 9:00 AM PT are processed
     the next business day. Occasionally the markets for US Government
     securities and money market instruments close early. On such days, the cut-
     off time for trades may be earlier.
 .    It is the nature of a mutual fund investment that the price you pay to
     purchase shares or the price you receive when you redeem shares is not
     determined until after a request has been received in proper form.
 .    We determine the Net Asset Value (NAV) of each class of the Fund's shares
     each business day after 9:00 AM PT by subtracting the Fund class's
     liabilities from its total assets, and then dividing the result by the
     total number of outstanding shares of that class. See the Statement of
     Additional Information for further disclosure.

DIVIDEND AND CAPITAL GAIN DISTRIBUTIONS:

 .    Are reinvested automatically to buy new shares of the Fund at NAV. The new
     shares are purchased at NAV generally on the day the income is paid. This
     option is automatically assigned to your account unless you specify another
     plan.
 .    Dividends are declared daily and paid monthly. Dividends for Saturdays,
     Sundays and Holidays are declared payable the preceding business day.


TAXES

We will pass on to you net investment income and net short-term capital gains
earned by a Fund as dividend distributions. These are taxable to you as ordinary
income. Corporate shareholders may be able to exclude a portion of dividend
income from their taxable income.

It is our policy to avoid capital gains on money market funds. Long-term capital
gains earned by a Fund will be passed on to you as capital gains and will be
taxable to you as long-term capital gains. In general, distributions are taxable
when paid. However, distributions declared in October, November and December and
distributed by the following January will be taxable as if they were paid on
December 31.

Your redemptions will ordinarily result in a taxable capital gain or loss,
depending on the amount you receive for your shares and the amount you paid for
them. Foreign shareholders may be subject to different tax treatment, including
withholding. In certain circumstances, U.S. residents may also be subject to tax
withholding.

Additional details about the tax consequences of investing are available to you
in the Statements of Additional Information. The discussion of taxes is only a
summary based on laws in effect as of the date of this Prospectus and is not a
substitute for careful tax planning.

guaranteed by the U.S.  Treasury and in notes, repurchase agreements and other

GENERAL RISK CONSIDERATIONS

You should carefully consider risks common to all mutual funds. Chief among
these risks is the following:

 .    Unlike bank deposits, such as CD's or savings accounts, mutual funds are
     NOT INSURED BY THE FDIC.
 .    We CANNOT GUARANTEE that any Fund will meet its investment objectives. In
     particular, we can not guarantee that we will be able to maintain a $1.00
     per share net asset value.
 .    You cannot recover through insurance any loss due to INVESTMENT PRACTICES,
     nor can the Fund, the selling agents or investment advisors make good any
     loss you might have.
 .    Investing in any mutual fund, including those deemed conservative, involve
     RISK, INCLUDING THE POSSIBLE LOSS OF ANY MONEY YOU INVEST.

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your tolerance and preferences. Some
mutual funds invest in assets that involve particular kinds of risk.

 .    Funds that invest in debt instruments, such as notes and bonds, are subject
     to CREDIT RISK and INTEREST-RATE RISK. Credit risk is the possiblity that
     an issuer of a security will be unable to make interest payments or repay
     principal. Interest-rate risk is the possibility that interest rates may
     increase and reduce the resale value of lower-paying securities in the
     Fund's portfolio. Debt instruments with longer maturities are generally
     more sensitive to interest rate changes than those with shorter maturities.
     Interest rate risk does not affect the interest paid by a debt instrument
     unless it is specifically designed to pay an adjustable rate.

The Fund's advisor may also use certain DERIVATIVE instruments such as options
or futures contracts. The term "derivatives" covers a wide number of investment
practices but in general it refers to a financial instrument whose value is
derived, at least in part, from the price of another security or a specified
index, asset or rate. Some derivatives may be more sensitive to interest rate
changes or market moves, and some may be susceptible to changes in yields or
values due to the structure of their contracts.

The following types of floating-rate derivative securities are not permitted
investments in the Funds:

 .    Capped floaters on which interest is not paid when market rates move above
     a certain level;
 .    Leveraged floaters whose interest rates reset based on a formula that
     magnifies changes in market interest rates;
 .    Range floaters on which interest is not paid in market interest rates move
     outside a specified range;
 .    Dual index floaters whose interest rate reset provisions are tied to more
     than one index; and
 .    Inverse floaters which reset in an opposite direction of their index.

Investment practices and risk levels are carefully monitored. Every attempt is
made to ensure that the risk exposure for each Fund remains within the
parameters of its objective.

What follows is a general list of the types of risks that may affect a given
Fund and a table showing some of the additional investment practices that each
Fund may use. Additional information about these practices is available in the
Statement of Additional Information.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule. If an issuer does default, the
affected security could lose all of its value, or be renegotiated at a lower
interest rate. Affected securities might also lose liquidity.  Credit risk
includes the risk that a party in a transaction may not be able to complete the
transaction as agreed.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value or
liquidity of investments in either country.

Information Risk--The risk that information about a security is either
unavailable or is inaccurate.
<PAGE>
 
             Administrative Money Market Prospectus (November 3, 1997, 1997) - 8

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security. Generally, when interest rates increase, the value of a
debt security decreases. The effect is usually more pronounced for securities
with longer dates to maturity.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of stock, bond or other security will
reduced by market activity. This is the basic risk associated with all
securities investments.

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation or region's industry,
government or markets.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security.

     requirements.

BUYING SHARES

You can buy Fund shares at Net Asset Value (NAV) through affiliate, franchise or
correspondent banks of Wells Fargo and other select institutions. Individual
investors interested in purchasing Administrative shares of the Funds should
contact an account representative at an institution and should understand the
following:

 .    share purchases are made through your Customer Account at an institution
     and are executed and confirmed according to the terms of Customer Account
     involved;
 .    institutions, acting on behalf of their customers, are usually holders of
     record of Administrative shares and maintain records reflecting their
     customers' beneficial ownership of the shares;
 .    institutions are responsible for transmitting purchase orders by their
     customers and delivering required payment on a timely basis;
 .    the exercise of voting rights and the delivery of shareholder
     communications from the Funds is governed by the customer's account
     agreement with the Institution;
 .    institutions may charge their customers account fees and may receive fees
     from us with respect to investments their customers have made with the
     Funds. See "The Organization of the Funds" for further details about these
     fees.


Additional Important Information about Investing:

 .    Read this prospectus carefully. Discuss any questions you have with your
     account representative. You may also ask for copies of the Statements of
     Additional Information. Copies are available free of charge from your
     account representative or by calling 1-800 260-5969.
 .    We process requests to buy or sell shares each business day at 12:00 Noon,
     Pacific Time. Any request we receive in proper form before 12:00 Noon PT is
     processed the same day. Requests we receive after 12:00 Noon PT are
     processed the next business day. Occasionally the markets for US Government
     securities and money market instruments close early. On such days, the cut-
     off time for trades may be earlier.
 .    It is the nature of a mutual fund investment that the price you pay to
     purchase shares or the price you receive when you redeem shares is not
     determined until after a request has been received in proper form.
 .    We determine the Net Asset Value (NAV) of each class of the Fund's shares
     each business day 12:00 noon and 1:00 PM PT. We determine the NAV by
     subtracting the Fund class's liabilities from its total assets, and then
     dividing the result by the total number of outstanding shares of that
     class. See the Statements of Additional Information for further disclosure.
 .    Your institution may require additional paperwork for certain types of
     account registrations, such as a Trust. Please speak to your account
     representative at the institution for details.


SELLING SHARES

Administrative shares held on behalf of an institution's customers must be
redeemed in accordance with the account agreement governing the customer's
account at the institution. Please read your account agreement with your
institution for rules governing selling shares. General Notes for Selling
Shares:

 .    We will process redemption requests we receive in proper form before 12:00
     P.M. Pacific Time, at the NAV determined on the same business day.
<PAGE>
 
                  Administrative Money Market Prospectus (November 3, 1997) - 12

 .    Redemption Proceeds are usually wired to the redeeming institution the
     following business day.
 .    We reserve the right to delay payment of redemption for up to ten days so
     that we may be reasonably certain that investments made by check have been
     collected. Payments of redemptions may also be delayed under extraordinary
     circumstances or as permitted by the SEC in order to protect remaining
     shareholders. Payments of redemptions may also be delayed up to seven days
     under normal circumstances, although it is not our policy to delay such
     payments.
 .    Generally, we pay redemption requests in cash, unless the redemption
     request is for more than $250,000 or 1% of the net assets of the Fund by a
     single shareholder over any ninety-day period. If a request for redemption
     is over these limits it may be to the detriment of existing shareholders.
     Therefore, we may pay the redemption in part or in whole in securities of
     equal value.

If you do not have a relationship with an Institution, you may redeem shares by
writing or calling us directly. Redemption proceeds in such cases are usually
sent by check unless a wire transfer is requested. We will act on instructions
that we reasonably believe to be genuine.

EXCHANGES

Exchanges between Stagecoach Funds are two transactions: a sale of one Fund and
the purchase of another. In general, the same rules and procedures that apply to
sales and purchases apply to exchanges. There are, however, additional factors
you should keep in mind while making or considering an exchange:

 .    You will need to read the Prospectus for the Fund into which you wish to
     exchange.
 .    Every exchange involves selling Fund shares and that sale may produce a
     capital gain or loss for federal income tax purposes.
 .    If you are making an initial investment into a new Fund through an
     exchange, you must exchange at least the minimum first purchase amount of
     the Fund you are redeeming, unless your balance has fallen below that
     amount due to market conditions.
 .    Any exchange between Funds you already own must meet the minimum redemption
     and subsequent purchase amounts for the Funds involved.
 .    In order to discourage market timing and excessive transaction expenses
     that must be borne by other shareholders, we reserve the right to limit or
     reject exchange orders. Generally, we will notify you 60 days in advance of
     any changes in your exchange privileges.

ADDITIONAL SERVICES AND POLICIES

DIVIDEND AND CAPITAL GAIN DISTRIBUTION OPTIONS

You may choose to do any of the following:

 .    AUTOMATIC REINVESTMENT OPTION - Lets you buy new shares of the same class
     of the Fund that generated the distributions. The new shares are purchased
     at NAV generally on the day the income is paid. This option is
     automatically assigned to your account unless you specify another plan.
 .    CHECK PAYMENT OPTION - Allows you to receive checks for distributions
     mailed to your address of record or to another name and address which you
     have specified in written, signature guaranteed instructions. If checks
     remain uncashed for six months or are undeliverable by the Post Office, we
     will reinvest the distributions at the earliest date possible.

TAXES

We will pass on to you net investment income and net short-term capital gains
earned by a Fund as dividend distributions. These are taxable to you as ordinary
income. Corporate shareholders may be able to exclude a portion of dividend
income from their taxable income.

Long-term capital gains earned by a Fund will be passed on to you as capital
gains and will be taxable to you as long-term capital gains. In general,
distributions are taxable when paid. However, distributions declared in October,
November and December and distributed by the following January will be taxable
as if they were paid on December 31.

Your redemptions will ordinarily result in a taxable capital gain or loss,
depending on the amount you receive for your shares and the amount you paid for
them. Foreign shareholders may be subject to different tax treatment, including
withholding. In certain circumstances, U.S. residents may also be subject to tax
withholding.

Additional details about the tax consequences of investing are available to you
in the Statements of Additional Information. The discussion of taxes is only a
summary based on laws in effect as of the date of this Prospectus and is not a
substitute for careful tax planning.

returns than those described here. Call Stephens Inc. at 1-800-643-9691 for

accounts, we reserve the right to close accounts that have fallen below the

conditions). You will be given an opportunity to make additional investments to
prevent account closure before any action is taken.

Glass-Steagall Act - Morrison & Foerster LLP, counsel to the Funds and special
counsel to Wells Fargo Bank, has advised us and Wells Fargo Bank that Wells
Fargo Bank and its affiliates may perform the services contemplated by the
Advisory Contracts and detailed in this Prospectus and the Statements of
Additional Information without violation of the Glass-Steagall Act. Counsel has
pointed out that future judicial or administrative decisions, or future federal
or state laws may prevent these entities from continuing in their roles.

Voting Rights--All shares of the Funds have equal voting rights and are voted in
the aggregate, rather than by series or class, unless the matter affects only
one series or class. A Fund's shareholder of record is entitled to one vote for
each share owned and fractional votes for each fractional share owned. For a
detailed description of voting rights, see the "Capital Stock" section of the

HOW TO READ THE FINANCIAL HIGHLIGHTS

After each Fund's Investment Objective and Investment Policies, charts are
provided showing important financial information about Fund. The charts are
called "Financial Highlights" and are designed to help you understand the past
performance of each Fund. The financial statements, from which these Financial
Highlights were derived, were audited by KPMG Peat Marwick LLP except as
indicated. The financial statements are available in the Fund's most recent
Annual Report and are available free of charge by calling 1-800-222-8222. Other
auditors audited statements for the Government and the Treasury Money Market
Funds for periods prior to October 1, 1995.  Here is an explanation of some
terms that will help you interpret these charts.

NET ASSET VALUE (NAV)--The value of one share of a class of a Fund, excluding
any sales charge. See the Glossary for a fuller definition.

NET INVESTMENT INCOME--When we receive dividend or interest payments from an
investment or earn trading profits, we deduct management fees, administrative
and other expenses and then record the result as net investment income. The
number in the financial highlights is the net investment income of a class
divided by the number of outstanding shares of that class. The amount
distributed to shareholders is listed under the heading "Less Distributions-
Dividends From Net Investment Income."

NET REALIZED AND UNREALIZED CAPITAL GAINS--We buy and sell investments
frequently. The profit on an investment sold for more than its purchase price is
a realized capital gain while any loss is a realized capital loss. An unrealized
gain or loss occurs when an investment gains or loses value but is not sold. The
number in this category is the total gains or losses of a class divided by the
number of outstanding fund shares for that class. The amount of capital gain or
loss per share that was passed on to shareholders is listed under the heading
"Less Distributions-Distributions From Net Realized Gains."

NET ASSETS--The value of the investments in a Fund's portfolio that are
attributable to a particular class of the Fund.

RATIO OF EXPENSES TO AVERAGE NET ASSETS--This ratio reflects the amount paid by
a Fund to cover the costs of its daily operations, and includes advisory,
administrative and other operating expenses. It is expressed as a percentage of
the average daily net assets of a class.

RATIO OF NET INVESTMENT INCOME (LOSS) TO AVERAGE NET ASSETS--This ratio is the
result of dividing net investment income (or loss) by average net assets.

PORTFOLIO TURNOVER--Portfolio turnover is expressed as a percentage of a Fund's
investment portfolio and reflects the trading activity in the portfolio. For
example, a Fund with a 50% portfolio turnover has sold and bought half of its
investment portfolio during the given period.

National Tax-Free Money Market Mutual Fund

INVESTMENT OBJECTIVE

     The National Tax-Free Money Market Mutual Fund seeks to provide investors
with a high level of income exempt from federal income tax, while preserving
capital and liquidity.

INVESTMENT POLICIES

     We actively manage a portfolio of high-quality, short-term instruments,
primarily municipal obligations with remaining maturities of 397 days or less.
Among the municipal obligations we buy are bonds, notes and commercial paper
issued by or on behalf of the states, territories and possessions of the United
States and their political subdivisions and other public authorities. Under
normal market conditions we invest substantially all of our assets in debt
obligations that are exempt from federal income tax. We maintain an overall
dollar-weighted average maturity of 90 days or less.

PORTFOLIO HOLDINGS

Under normal market conditions, we invest:
 . at least 80% of our assets in municipal obligations that provide interest free
  exempt from federal income tax and not subject to the federal alternative
  minimum tax;
 . in obligations rated within the two highest categories by nationally
  recognized ratings organizations.
We may also invest up to 20% of our assets in permitted taxable investments as a
defensive measure due to unusual market conditions or to maintain liquidity.

IMPORTANT RISK FACTORS

For general information on risk, please see page ___.

Up to 25% or more of our assets in municipal obligations may be related in such
a way that political, economic or business developments affecting one obligation
would affect the others. For example, we may own different obligations that pay
interest based on the revenue of similar projects.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value. Fluctuations in share value may cause a loss or gain in principal.
Generally, short-term funds do not earn as high a level of income as funds that
invest in longer-term instruments.  No government agency either directly or
indirectly insures or guarantees the performance of the Fund.

ADDITIONAL FUND FACTS

Although it is our intention to reduce such exposure, a portion of the income
earned may be subject to the federal alternative minimum tax. We will send you a
letter each year informing you what percentage, if any, may be subject.

Treasury Money Market Mutual Fund

INVESTMENT OBJECTIVE

     The Treasury Money Market Mutual Fund seeks to provide investors with
current income and stability of principal.

INVESTMENT POLICIES

We actively manage a portfolio exclusively composed of obligations issued or
guaranteed by the U.S.  Treasury and in notes, repurchase agreements and other
instruments collateralized or secured by Treasury obligations. We buy
obligations with remaining maturities of 397 days or less. We maintain an
overall dollar-weighted average maturity of 90 days or less.

PORTFOLIO HOLDINGS

Under normal market conditions, we invest:
 . in U.S. Treasury obligations;
 . in repurchase agreements collateralized by U.S. Treasury obligations;
As a temporary defensive measure, or to maintain liquidity, we may invest in
shares of other mutual funds that have similar investment objectives.

IMPORTANT RISK FACTORS

For general information on risk, please see page ___.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value. Fluctuations in share value may cause a loss or gain in principal.
Generally, short-term funds do not earn as high a level of income as funds that
invest in longer-term instruments.  The U.S. Treasury does not directly or
indirectly insures or guarantees the performance of the Fund.

ADDITIONAL FUND FACTS

Treasury obligations have historically involved little risk of loss of principal
if held to maturity. However, fluctuations in market interest rates may cause
the market value of Treasury obligations in the Fund's portfolio to fluctuate.

GENERAL RISK CONSIDERATIONS

You should carefully consider risks common to all mutual funds. Chief among
these risks is the following:

 . Unlike bank deposits, such as CD's or savings accounts, mutual funds are NOT
  INSURED BY THE FDIC.
 . We CANNOT GUARANTEE that any Fund will meet its investment objectives. In
  particular, we can not guarantee that we will be able to maintain a $1.00
  per share net asset value.
 . You cannot recover through insurance any loss due to INVESTMENT PRACTICES, nor
  can the Fund, the selling agents or investment advisors make good any loss
  you might have.
 . Investing in any mutual fund, including those deemed conservative, involve
  RISK, INCLUDING THE POSSIBLE LOSS OF ANY MONEY YOU INVEST.

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your tolerance and preferences. Some
mutual funds invest in assets that involve particular kinds of risk.

 . Funds that invest in debt instruments, such as notes and bonds, are subject to
  CREDIT RISK and INTEREST-RATE RISK. Credit risk is the possiblity that an
  issuer of a security will be unable to make interest payments or repay
  principal. Interest-rate risk is the possibility that interest rates may
  increase and reduce the resale value of lower-paying securities in the Fund's
  portfolio. Debt instruments with longer maturities are generally more
  sensitive to interest rate changes than those with shorter maturities.
  Interest rate risk does not affect the interest paid by a debt instrument
  unless it is specifically designed to pay an adjustable rate.

The Fund's advisor may also use certain DERIVATIVE instruments such as options
or futures contracts. The term "derivatives" covers a wide number of investment
practices but in general it refers to a financial instrument whose value is
derived, at least in part, from the price of another security or a specified
index, asset or rate. Some derivatives may be more sensitive to interest rate
changes or market moves, and some may be susceptible to changes in yields or
values due to the structure of their contracts.

The following types of floating-rate derivative securities are not permitted
investments in the Funds:

 . Capped floaters on which interest is not paid when market rates move above a
  certain level;
 . Leveraged floaters whose interest rates reset based on a formula that
  magnifies changes in market interest rates;
 . Range floaters on which interest is not paid in market interest rates move
  outside a specified range;
 . Dual index floaters whose interest rate reset provisions are tied to more than
  one index; and
 . Inverse floaters which reset in an opposite direction of their index.

Investment practices and risk levels are carefully monitored. Every attempt is
made to ensure that the risk exposure for each Fund remains within the
parameters of its objective.

What follows is a general list of the types of risks that may affect a given
Fund and a table showing some of the additional investment practices that each
Fund may use. Additional information about these practices is available in the
Statement of Additional Information.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule. If an issuer does default, the
affected security could lose all of its value, or be renegotiated at a lower
interest rate. Affected securities might also lose liquidity.  Credit risk
includes the risk that a party in a transaction may not be able to complete the
transaction as agreed.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value or
liquidity of investments in either country.
<PAGE>
 
                           Inst. Money Market Prospectus (November 3, 1997) - 13

Information Risk--The risk that information about a security is either
unavailable or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security. Generally, when interest rates increase, the value of a
debt security decreases. The effect is usually more pronounced for securities
with longer dates to maturity.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of stock, bond or other security will
reduced by market activity. This is the basic risk associated with all
securities investments.

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation or region's industry,
government or markets.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security.

YOUR ACCOUNT

Minimum Investments:
 . $5,000,000.00 per Fund minimum initial investment;
 . $25,000.00 per Fund for all investments after the first;
 . Investors in certain various fiduciary accounts and certain other investors
  are not subject to minimum initial or subsequent investment amount
  requirements.

BUYING SHARES

You can buy Fund shares at Net Asset Value (NAV) through affiliate, franchise or
correspondent banks of Wells Fargo and other select institutions. Individual
investors interested in purchasing Institutional shares of the Funds should
contact an account representative at an institution and should understand the
following:

 . share purchases are made through your Customer Account at an institution and
  are executed and confirmed according to the terms of Customer Account
  involved;
 . institutions, acting on behalf of their customers, are usually holders of
  record of Institutional shares and maintain records reflecting their
  customers' beneficial ownership of the shares;
 . institutions are responsible for transmitting purchase orders by their
  customers and delivering required payment on a timely basis;
 . the exercise of voting rights and the delivery of shareholder communications
  from the Funds is governed by the customer's account agreement with the
  Institution;
 . institutions may charge their customers account fees and may receive fees from
  us with respect to investments their customers have made with the Funds.
  See "The Organization of the Funds" for further details about these fees.


Additional Important Information about Investing:

 . Read this prospectus carefully. Discuss any questions you have with your
  account representative. You may also ask for copies of the Statements of
  Additional Information. Copies are available free of charge from your account
  representative or by calling 1-800 260-5969.
 . We process requests to buy or sell shares each business day at 12:00 Noon,
  Pacific Time. Any request we receive in proper form before 12:00 Noon PT is
  processed the same day. Requests we receive after 12:00 Noon PT are processed
  the next business day. Occasionally the markets for US Government securities
  and money market instruments close early. On such days, the cut-off time for
  trades may be earlier.
 . It is the nature of a mutual fund investment that the price you pay to
  purchase shares or the price you receive when you redeem shares is not
  determined until after a request has been received in proper form.
 . We determine the Net Asset Value (NAV) of each class of the Fund's shares each
  business day 12:00 noon and 1:00 PM PT. We determine the NAV by subtracting
  the Fund class's liabilities from its total assets, and then dividing the
  result by the total number of outstanding shares of that class. See the
  Statements of Additional Information for further disclosure.
 . Your institution may require additional paperwork for certain types of account
  registrations, such as a Trust. Please speak to your account representative
  at the institution for details.


SELLING SHARES

Institutional shares held on behalf of an institution's customers must be
redeemed in accordance with the account agreement governing the customer's
account at the institution. Please read your account agreement with your
institution for rules governing selling shares. General Notes for Selling
Shares:

 . We will process redemption requests we receive in proper form before 12:00
  P.M. Pacific Time, at the NAV determined on the same business day.
 . Redemption Proceeds are usually wired to the redeeming institution the
  following business day.
<PAGE>
 
                           Inst. Money Market Prospectus (November 3, 1997) - 17


 . We reserve the right to delay payment of redemption for up to ten days so that
  we may be reasonably certain that investments made by check have been
  collected. Payments of redemptions may also be delayed under extraordinary
  circumstances or as permitted by the SEC in order to protect remaining
  shareholders. Payments of redemptions may also be delayed up to seven days
  under normal circumstances, although it is not our policy to delay such
  payments.
 . Generally, we pay redemption requests in cash, unless the redemption request
  is for more than $250,000 or 1% of the net assets of the Fund by a single
  shareholder over any ninety-day period. If a request for redemption is over
  these limits it may be to the detriment of existing shareholders. Therefore,
  we may pay the redemption in part or in whole in securities of equal value.

If you do not have a relationship with an Institution, you may redeem shares by
writing or calling us directly. Redemption proceeds in such cases are usually
sent by check unless a wire transfer is requested. We will act on instructions
that we reasonably believe to be genuine.

EXCHANGES

Exchanges between Stagecoach Funds are two transactions: a sale of one Fund and
the purchase of another. In general, the same rules and procedures that apply to
sales and purchases apply to exchanges. There are, however, additional factors
you should keep in mind while making or considering an exchange:
 . You will need to read the Prospectus for the Fund into which you wish to
  exchange.
 . Every exchange involves selling Fund shares and that sale may produce a
  capital gain or loss for federal income tax purposes.
 . If you are making an initial investment into a new Fund through an exchange,
  you must exchange at least the minimum first purchase amount of the Fund
  you are redeeming, unless your balance has fallen below that amount due to
  market conditions.
 . Any exchange between Funds you already own must meet the minimum redemption
  and subsequent purchase amounts for the Funds involved.
 . In order to discourage market timing and excessive transaction expenses that
  must be borne by other shareholders, we reserve the right to limit or
  reject exchange orders. Generally, we will notify you 60 days in advance of
  any changes in your exchange privileges.

ADDITIONAL SERVICES AND POLICIES

DIVIDEND AND CAPITAL GAIN DISTRIBUTION OPTIONS

You may choose to do any of the following:
 . AUTOMATIC REINVESTMENT OPTION - Lets you buy new shares of the same class of
  the Fund that generated the distributions. The new shares are purchased at
  NAV generally on the day the income is paid. This option is automatically
  assigned to your account unless you specify another plan.
 . CHECK PAYMENT OPTION - Allows you to receive checks for distributions mailed
  to your address of record or to another name and address which you have
  specified in written, signature guaranteed instructions. If checks remain
  uncashed for six months or are undeliverable by the Post Office, we will
  reinvest the distributions at the earliest date possible.


TAXES

We will pass on to you net investment income and net short-term capital gains
earned by a Fund as dividend distributions. These are taxable to you as ordinary
income. Corporate shareholders may be able to exclude a portion of dividend
income from their taxable income.

Long-term capital gains earned by a Fund will be passed on to you as capital
gains and will be taxable to you as long-term capital gains. In general,
distributions are taxable when paid. However, distributions declared in October,
November and December and distributed by the following January will be taxable
as if they were paid on December 31.

Your redemptions will ordinarily result in a taxable capital gain or loss,
depending on the amount you receive for your shares and the amount you paid for
them. Foreign shareholders may be subject to different tax treatment, including
withholding. In certain circumstances, U.S. residents may also be subject to tax
withholding.

Additional details about the tax consequences of investing are available to you
in the Statements of Additional Information. The discussion of taxes is only a
summary based on laws in effect as of the date of this Prospectus and is not a
substitute for careful tax planning.

HOW TO READ THE FINANCIAL HIGHLIGHTS

After each Fund's Investment Objective and Investment Policies, charts are
provided showing important financial information about Fund. The charts are
called "Financial Highlights" and are designed to help you understand the past
performance of each Fund. The financial statements, from which these Financial
Highlights were derived, were audited by KPMG Peat Marwick LLP except as
indicated. The financial statements are available in the Fund's most recent
Annual Report and are available free of charge by calling 1-800-222-8222. Other
auditors audited statements for the Government and the Treasury Money Market
Funds for periods prior to October 1, 1995.  Here is an explanation of some
terms that will help you interpret these charts.

NET ASSET VALUE (NAV)--The value of one share of a class of a Fund, excluding
any sales charge. See the Glossary for a fuller definition.

NET INVESTMENT INCOME--When we receive dividend or interest payments from an
investment or earn trading profits, we deduct management fees, administrative
and other expenses and then record the result as net investment income. The
number in the financial highlights is the net investment income of a class
divided by the number of outstanding shares of that class. The amount
distributed to shareholders is listed under the heading "Less Distributions-
Dividends From Net Investment Income."

NET REALIZED AND UNREALIZED CAPITAL GAINS--We buy and sell investments
frequently. The profit on an investment sold for more than its purchase price is
a realized capital gain while any loss is a realized capital loss. An unrealized
gain or loss occurs when an investment gains or loses value but is not sold. The
number in this category is the total gains or losses of a class divided by the
number of outstanding fund shares for that class. The amount of capital gain or
loss per share that was passed on to shareholders is listed under the heading
"Less Distributions-Distributions From Net Realized Gains."

NET ASSETS--The value of the investments in a Fund's portfolio that are
attributable to a particular class of the Fund.

RATIO OF EXPENSES TO AVERAGE NET ASSETS--This ratio reflects the amount paid by
a Fund to cover the costs of its daily operations, and includes advisory,
administrative and other operating expenses. It is expressed as a percentage of
the average daily net assets of a class.

RATIO OF NET INVESTMENT INCOME (LOSS) TO AVERAGE NET ASSETS--This ratio is the
result of dividing net investment income (or loss) by average net assets.

PORTFOLIO TURNOVER--Portfolio turnover is expressed as a percentage of a Fund's
investment portfolio and reflects the trading activity in the portfolio. For
example, a Fund with a 50% portfolio turnover has sold and bought half of its
investment portfolio during the given period.

INVESTMENT POLICIES

     We pursue this objective by actively manage a portfolio consisting of a
broad range of U.S. dollar-denominated, high quality money market instruments,
including debt obligations with remaining maturities of 397 days or less. We
maintain an overall dollar-weighted average maturity of 90 days or less. We may

PORTFOLIO HOLDINGS

Under normal market conditions, we invest in:

Among the investments not permitted are capped floaters, leveraged floaters,
range floaters, dual index floaters and inverse floaters.

There is no guarantee that we will be able to maintain a $1.00 per share net

Generally, short-term funds do not earn as high a level of income as funds that
invest in longer-term instruments.  No government agency either directly or
indirectly insures or guarantees the performance of the Fund.

Treasury Money Market Mutual Fund

INVESTMENT OBJECTIVE

     The Treasury Money Market Mutual Fund seeks to provide investors with
current income and stability of principal.

INVESTMENT POLICIES

We actively manage a portfolio exclusively composed of obligations issued or
guaranteed by the U.S.  Treasury and in notes, repurchase agreements and other
instruments collateralized or secured by Treasury obligations. We buy
obligations with remaining maturities of 397 days or less. We maintain an
overall dollar-weighted average maturity of 90 days or less.

PORTFOLIO HOLDINGS

Under normal market conditions, we invest:
 .    in U.S. Treasury obligations;
 .    in repurchase agreements collateralized by U.S. Treasury obligations;
As a temporary defensive measure, or to maintain liquidity, we may invest in
shares of other mutual funds that have similar investment objectives.

IMPORTANT RISK FACTORS

For general information on risk, please see page ___.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value. Fluctuations in share value may cause a loss or gain in principal.
Generally, short-term funds do not earn as high a level of income as funds that
invest in longer-term instruments.  The U.S. Treasury does not directly or
indirectly insures or guarantees the performance of the Fund.

ADDITIONAL FUND FACTS

Treasury obligations have historically involved little risk of loss of principal
if held to maturity. However, fluctuations in market interest rates may cause
the market value of Treasury obligations in the Fund's portfolio to fluctuate.

GENERAL RISK CONSIDERATIONS

You should carefully consider risks common to all mutual funds. Chief among
these risks is the following:
 .    Unlike bank deposits, such as CD's or savings accounts, mutual funds are
     not insured by the FDIC.
 .    We cannot guarantee that any Fund will meet its investment objectives. In
     particular, we can not guarantee that we will be able to maintain a $1.00
     per share net asset value.
 .    You cannot recover through insurance any loss due to investment practices,
     nor can the Fund, the selling agents or investment advisors make good any
     loss you might have.
 .    Investing in any mutual fund, including those deemed conservative, involve
     risk, including the possible loss of any money you invest.

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your tolerance and preferences. Some
mutual funds invest in assets that involve particular kinds of risk.

 .    Funds that invest in debt instruments, such as notes and bonds, are subject
     to credit risk and interest-rate risk. Credit risk is the possiblity that
     an issuer of a security will be unable to make interest payments or repay
     principal. Interest-rate risk is the possibility that interest rates may
     increase and reduce the resale value of lower-paying securities in the
     Fund's portfolio. Debt instruments with longer maturities are generally
     more sensitive to interest rate changes than those with shorter maturities.
     Interest rate risk does not affect the interest paid by a debt instrument
     unless it is specifically designed to pay an adjustable rate.

The Fund's advisor may also use certain derivative instruments such as options
or futures contracts. The term "derivatives" covers a wide number of investment
practices but in general it refers to a financial instrument whose value is
derived, at least in part, from the price of another security or a specified
index, asset or rate. Some derivatives may be more sensitive to interest rate
changes or market moves, and some may be susceptible to changes in yields or
values due to the structure of their contracts.

The following types of floating-rate derivative securities are not permitted
investments in the Funds:

 .    Capped floaters on which interest is not paid when market rates move above
     a certain level;
 .    Leveraged floaters whose interest rates reset based on a formula that
     magnifies changes in market interest rates;
 .    Range floaters on which interest is not paid in market interest rates move
     outside a specified range;
 .    Dual index floaters whose interest rate reset provisions are tied to more
     than one index; and
 .    Inverse floaters which reset in an opposite direction of their index.

Investment practices and risk levels are carefully monitored. Every attempt is
made to ensure that the risk exposure for each Fund remains within the
parameters of its objective.

What follows is a general list of the types of risks that may affect a given
Fund and a table showing some of the additional investment practices that each
Fund may use. Additional information about these practices is available in the
Statement of Additional Information.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule. If an issuer does default, the
affected security could lose all of its value, or be renegotiated at a lower
interest rate. Affected securities might also lose liquidity.  Credit risk
includes the risk that a party in a transaction may not be able to complete the
transaction as agreed.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value or
liquidity of investments in either country.

Information Risk--The risk that information about a security is either
unavailable or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security. Generally, when interest rates increase, the value of a
debt security decreases. The effect is usually more pronounced for securities
with longer dates to maturity.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of stock, bond or other security will
reduced by market activity. This is the basic risk associated with all
securities investments.

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation or region's industry,
government or markets.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security.

Buying Shares

You can buy Fund shares at Net Asset Value (NAV) through affiliate, franchise or
correspondent banks of Wells Fargo and other select institutions. Individual
investors interested in purchasing Service shares of the Funds should contact an
account representative at an institution and should understand the following:

 .    share purchases are made through your Customer Account at an institution
     and are executed and confirmed according to the terms of Customer Account
     involved;
 .    customers of an institution's trust division, as may officers, directors
     and employees of the institution;
 .    there are no minimum investment requirements, although a institution may
     impose account minimums in connection with investments in the Funds;
 .    we confirm purchases and redemptions to the institution;
 .    institutions, acting on behalf of their customers, are usually holders of
     record of Service shares and maintain records reflecting their customers'
     beneficial ownership of the shares;
 .    institutions are responsible for transmitting purchase orders by their
     customers and delivering required payment on a timely basis;
 .    the exercise of voting rights and the delivery of shareholder
     communications from the Funds is governed by the customer's account
     agreement with the Institution;
 .    institutions may charge their customers account fees and may receive fees
     from us with respect to investments their customers have made with the
     Funds. See "The Organization of the Funds" for further details about these
     fees.


Additional Important Information about Investing:

 .    Read this prospectus carefully. Discuss any questions you have with your
     account representative. You may also ask for copies of the Statements of
     Additional Information. Copies are available free of charge from your
     account representative or by calling 1-800 260-5969.
 .    We process requests to buy or sell shares each business day at 12:00 Noon,
     Pacific Time. Any request we receive in proper form before 12:00 Noon PT is
     processed the same day. Requests we receive after 12:00 Noon PT are
     processed the next business day. Occasionally the markets for US Government
     securities and money market instruments close early. On such days, the cut-
     off time for trades may be earlier.
 .    It is the nature of a mutual fund investment that the price you pay to
     purchase shares or the price you receive when you redeem shares is not
     determined until after a request has been received in proper form.
 .    We determine the Net Asset Value (NAV) of each class of the Fund's shares
     each business day 12:00 noon and 1:00 PM PT. We determine the NAV by
     subtracting the Fund class's liabilities from its total assets, and then
     dividing the result by the total number of outstanding shares of that
     class. See the Statements of Additional Information for further disclosure.
 .    Your institution may require additional paperwork for certain types of
     account registrations, such as a Trust. Please speak to your account
     representative at the institution for details.


Selling Shares

Service shares held on behalf of an institution's customers must be redeemed in
accordance with the account agreement governing the customer's account at the
institution. Please read your account agreement with your institution for rules
governing selling shares. General Notes for Selling Shares:

 .    We will process redemption requests we receive in proper form before 12:00
     P.M. Pacific Time, at the NAV determined on the same business day.
 .    Redemption Proceeds are usually wired to the redeeming institution the
     following business day.
 .    We reserve the right to delay payment of redemption for up to ten days so
     that we may be reasonably certain that investments made by check have been
     collected. Payments of redemptions may also be delayed under extraordinary
     circumstances or as permitted by the SEC in order to protect remaining
<PAGE>
 
                                 Money Market Prospectus (October 27, 1997) - 15

     shareholders. Payments of redemptions may also be delayed up to seven days
     under normal circumstances, although it is not our policy to delay such
     payments.
 .    Generally, we pay redemption requests in cash, unless the redemption
     request is for more than $250,000 or 1% of the net assets of the Fund by a
     single shareholder over any ninety-day period. If a request for redemption
     is over these limits it may be to the detriment of existing shareholders.
     Therefore, we may pay the redemption in part or in whole in securities of
     equal value.

If you do not have a relationship with an Institution, you may redeem shares by
writing or calling us directly. Redemption proceeds in such cases are usually
sent by check unless a wire transfer is requested. We will act on instructions
that we reasonably believe to be genuine.

Exchanges

Exchanges between Stagecoach Funds are two transactions: a sale of one Fund and
the purchase of another. In general, the same rules and procedures that apply to
sales and purchases apply to exchanges. There are, however, additional factors
you should keep in mind while making or considering an exchange:

 .    You will need to read the Prospectus for the Fund into which you wish to
     exchange.
 .    Every exchange involves selling Fund shares and that sale may produce a
     capital gain or loss for federal income tax purposes.
 .    If you are making an initial investment into a new Fund through an
     exchange, you must exchange at least the minimum first purchase amount of
     the Fund you are redeeming, unless your balance has fallen below that
     amount due to market conditions.
 .    Any exchange between Funds you already own must meet the minimum redemption
     and subsequent purchase amounts for the Funds involved.
 .    In order to discourage market timing and excessive transaction expenses
     that must be borne by other shareholders, we reserve the right to limit or
     reject exchange orders. Generally, we will notify you 60 days in advance of
     any changes in your exchange privileges.

ADDITIONAL SERVICES AND POLICIES

DIVIDEND AND CAPITAL GAIN DISTRIBUTION OPTIONS

You may choose to do any of the following:

 .    AUTOMATIC REINVESTMENT OPTION - Lets you buy new shares of the same class
     of the Fund that generated the distributions. The new shares are purchased
     at NAV generally on the day the income is paid. This option is
     automatically assigned to your account unless you specify another plan.
 .    CHECK PAYMENT OPTION - Allows you to receive checks for distributions
     mailed to your address of record or to another name and address which you
     have specified in written, signature guaranteed instructions. If checks
     remain uncashed for six months or are undeliverable by the Post Office, we
     will reinvest the distributions at the earliest date possible.

TAXES

We will pass on to you net investment income and net short-term capital gains
earned by a Fund as dividend distributions. These are taxable to you as ordinary
income. Corporate shareholders may be able to exclude a portion of dividend
income from their taxable income.

Long-term capital gains earned by a Fund will be passed on to you as capital
gains and will be taxable to you as long-term capital gains. In general,
distributions are taxable when paid. However, distributions declared in October,
November and December and distributed by the following January will be taxable
as if they were paid on December 31.

Your redemptions will ordinarily result in a taxable capital gain or loss,
depending on the amount you receive for your shares and the amount you paid for
them. Foreign shareholders may be subject to different tax treatment, including
withholding. In certain circumstances, U.S. residents may also be subject to tax
withholding.

Additional details about the tax consequences of investing are available to you
in the Statements of Additional Information. The discussion of taxes is only a
summary based on laws in effect as of the date of this Prospectus and is not a
substitute for careful tax planning.


SPECIAL NOTICES:

the Fund's adviser. In connection with the merger of First Interstate Bancorp

the Funds may offer additional share classes with different expenses and returns
than those described here. Call Stephens Inc. at 1-800-643-9691 for information
on these or other investment options in the Funds.

Minimum Account Value - Due to the expense involved in maintaining low-balance
accounts, we reserve the right to close accounts that have fallen below the
$1,000,000.00 minimum balance due to redemptions (as opposed to market
conditions). You will be given an opportunity to make additional investments to
prevent account closure before any action is taken.

Statements - Institutions or their nominees typically send their investors a
confirmation or statement of account after every transaction that affects their
share balance. We will send any necessary tax reporting documents in January,
and will send Annual and Semi-Annual Reports each year.

Statements of Additional Information- Additional information about some of the
topics discussed in this Prospectus as well as details about return
calculations, distribution plans, servicing plans, tax issues and other
important issues are available in the Statement of Additional Information for
each Fund. The Statement of Additional Information should be read along with
this Prospectus and may be obtained free of charge by calling Investor Services
at 1 800-222-8222.

Glass-Steagall Act - Morrison & Foerster LLP, counsel to the Funds and special
counsel to Wells Fargo Bank, has advised us and Wells Fargo Bank that Wells
Fargo Bank and its affiliates may perform the services contemplated by the
Advisory Contracts and detailed in this Prospectus and the Statements of
Additional Information without violation of the Glass-Steagall Act. Counsel has
pointed out that future judicial or administrative decisions, or future federal
or state laws may prevent these entities from continuing in their roles.

Voting Rights--All shares of the Funds have equal voting rights and are voted in
the aggregate, rather than by series or class, unless the matter affects only
one series or class. A Fund's shareholder of record is entitled to one vote for
each share owned and fractional votes for each fractional share owned. For a
detailed description of voting rights, see the "Capital Stock" section of the
SAI.

SUMMARY INFORMATION

Summary of Stagecoach Institutional Tax-Free Income Funds: The Funds described
in this Prospectus invest primarily in municipal debt securities and seek
monthly income free of federal, and in some cases, state income taxes. Each Fund
is an open-end management investment company.

Should you consider investing? Yes, if:
 .    you are looking for tax-free income or you are in a high-tax bracket and
     wish to reduce you tax liability;
 .    you are looking for monthly income;
 .    you are looking for more stability of principal than equity funds typically
     provide;
 .    you are willing to accept the risks of income investing, including the risk
     that share prices may rise and fall.

You should not consider investing if:
 .    you are looking for FDIC coverage or guaranteed rates of return;
 .    you are unwilling to accept that you may lose money on your investment;
 .    you are unwilling to accept the risks involved in the bond market; and
 .    you are seeking aggressive long-term total return.

Key Information:

Dividends: We will pay dividends, if any, monthly.

Tax-Free: Take advantage of tax laws that allow the income from certain
investments to be exempted from federal and, in some cases, state personal
income tax. Capital gains, whether declared by a fund or accrued by the
shareholder, are generally taxable.

Alternative Minimum Tax: You may be subject to the Alternative Minimum Tax (AMT)
on your tax-free distributions. Please check with a tax advisor if you are
uncertain as to whether or not this might apply to you.

Key Terms: "Municipal obligations" is used in this Prospectus refers to a broad
variety of fixed-income and variable-rate securities issued by or on behalf of
the states, territories and possessions of the United States. "Instruments" is
used to describe a negotiable contract or promise to pay money, such as a
Certificate of Deposit or a Banker's Acceptance.

What are Institutional shares?: Institutional shares are typically held for your
benefit by affiliate, franchise or correspondent banks of Wells Fargo and other
select institutions. The Funds offered here are available in other share
classes. A prospectus for additional share classes can be obtained by calling 1
800-222-8222.

Who are "We"?: In this Prospectus, "We"  generally means the Stagecoach Funds.
"We" sometimes refers to the Investment Advisor or other companies hired by the
Fund to perform services. The section on "Organization and Management of The
Funds" further explains how the Funds are organized.

Who are "You"?: In this Prospectus, "You" means the shareholder.

Italics: Throughout this prospectus, words will appear in italicized print. This
means that the word is defined in the glossary beginning on page ___.

HOW TO READ THE FINANCIAL HIGHLIGHTS

After each Fund's Investment Objective and Investment Policies, charts are
provided showing important financial information about Fund. The charts are
called "Financial Highlights" and are designed to help you understand the past
performance of each Fund. The financial statements, from which these Financial
Highlights were derived, were audited by KPMG Peat Marwick LLP except as
indicated. The financial statements are available in the Fund's most recent
Annual Report and are available free of charge by calling 1-800-222-8222.. Other
auditors audited statements for the Arizona Tax-Free, National Tax-Free and
Oregon Tax-Free Funds for periods prior to October 1, 1995.  Here is an
explanation of some terms that will help you interpret these charts.

NET ASSET VALUE (NAV)--The value of one share of a class of a Fund, excluding
any sales charge. See the Glossary for a fuller definition.

NET INVESTMENT INCOME--When we receive dividend or interest payments from an
investment or earn trading profits, we deduct management fees, administrative
and other expenses and then record the result as net investment income. The
number in the financial highlights is the net investment income of a class
divided by the number of outstanding shares of that class. The amount
distributed to shareholders is listed under the heading "Less Distributions-
Dividends from Net Investment Income."

NET REALIZED AND UNREALIZED CAPITAL GAINS--We buy and sell investments
frequently. The profit on an investment sold for more than its purchase price is
a realized capital gain while any loss is a realized capital loss. An unrealized
gain or loss occurs when an investment gains or loses value but is not sold. The
number in this category is the total gains or losses of a class divided by the
number of outstanding fund shares for that class. The amount of capital gain or
loss per share that was passed on to shareholders is listed under the heading
"Less Distributions-Distributions From Net Realized Gains."

NET ASSETS--The value of the investments in a Fund's portfolio that are
attributable to a particular class of the Fund.

RATIO OF EXPENSES TO AVERAGE NET ASSETS--This ratio reflects the amount paid by
a Fund to cover the costs of its daily operations, and includes advisory,
administrative and other operating expenses. It is expressed as a percentage of
the average daily net assets of a class.

RATIO OF NET INVESTMENT INCOME (LOSS) TO AVERAGE NET ASSETS--This ratio is the
result of dividing net investment income (or loss) by average net assets.

PORTFOLIO TURNOVER--Portfolio turnover reflects the trading activity in the
Fund's portfolio and is expressed as a percentage of a Fund's investment
portfolio. For example, a Fund with a 50% portfolio turnover has sold and bought
half of its investment portfolio during the given period.

TOTAL RETURN--The annual return on an investment, including any appreciation or
decline in share value, assumes reinvestment of all dividends and capital gains,
and excludes sales loads.

             Institutional Tax-Free Income Prospectus (November 2, 1997) 6


Arizona Tax-Free Fund

Portfolio Managers:  Laura Milner (since 9/96)
- -------------------  
                     Mary Gail Walton (since 2/97)                        

INVESTMENT OBJECTIVE

          The Arizona Tax-Free Fund seeks to provide investors with income
exempt from federal income tax and Arizona personal income tax.

INVESTMENT POLICIES

          We actively manage a portfolio of municipal obligations. We buy
municipal obligations of any maturity length. The portfolio's weighted average
maturity will vary depending on market conditions, economic conditions including
interest rates, the differences in yields between obligations of different
maturity lengths and other factors. There is no required range for the
portfolio's average maturity. Generally speaking, we will attempt to capture
greater total return by increasing maturity when we expect interest rates to
decline, and attempt to preserve capital by shortening maturity when interest
rates are expected to increase.


PORTFOLIO HOLDINGS

Under normal market conditions, we invest:
 .    at least 80% of our assets in municipal obligations that pay interest
     exempt from federal income tax;
 .    at least 65% of our assets in municipal obligations that pay interest
     exempt from Arizona personal income tax;
 .    in municipal obligations rated in the three highest credit categories by
     nationally recognized credit rating organizations; and
 .    no more that 10% of assets obligations rated in the fourth highest category
     if enough suitable investments in the three highest categories cannot be
     found.
We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interest of shareholders to
do so.
 

IMPORTANT RISK FACTORS

For general information on risk, please see page ___.

     The Fund is considered non-diversified according to the 1940 Investment
Company Act. The majority of the issuers of the securities in the portfolio are
located within Arizona. Non-diversified, geographically concentrated Funds are
riskier than similar Funds that are diversified or spread their investments over
several geographic areas. Default by a single security in the portfolio may have
a greater negative affect than a similar default in a diversified portfolio.
 
ADDITIONAL FUND FACTS

     Distribution income earned may be subject to the federal alternative
minimum tax.

California Tax-Free Bond Fund

                    Laura Milner (since 9/96)


INVESTMENT OBJECTIVE

     The California Tax-Free Bond Fund seeks to provide investors with a high
level of income exempt from federal income tax and California personal income
tax, while preserving capital, by investing in medium- to long-term, investment-
grade municipal securities.

INVESTMENT POLICIES

     We actively manage a portfolio of municipal obligations. We buy municipal
obligations of any maturity length, but we invest substantially all of our
assets in securities with remaining maturities of 2 to 10 years (medium term) or
10 years or longer (long term). We have some flexibility in setting the
portfolio's dollar-weighted average maturity. Generally speaking, we will
attempt to capture greater total return by increasing dollar-weighted average
maturity when we expect interest rates to decline, and attempt to preserve
capital by shortening maturity when interest rates are expected to increase.

PORTFOLIO HOLDINGS

Under normal market conditions, we invest:
 .    at least 80% of our assets in municipal obligations that pay interest
     exempt from federal income tax;
 .    at least 65% of our assets in municipal obligations that pay interest
     exempt from California personal income tax;
 .    in municipal obligations rated in the three highest credit categories by
     nationally recognized credit rating organizations; or
 .    in municipal obligations rated in the fourth highest category if enough
     suitable investments in the three highest categories cannot be found.
We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interest of shareholders to
do so.

IMPORTANT RISK FACTORS

For general information on risk, please see page ___.

     The Fund is considered non-diversified according to the 1940 Investment
Company Act. The majority of the issuers of the securities in the portfolio are
located within California. Non-diversified, geographically concentrated Funds
are riskier than similar Funds that are diversified or spread their investments
over several geographic areas. Default by a single security in the portfolio may
have a greater negative affect than a similar default in a diversified
portfolio.
 

ADDITIONAL FUND FACTS

     Distribution income earned may be subject to the federal alternative
minimum tax. See page ___ for Historical Fund information.

INVESTMENT POLICIES

     We actively manage a portfolio of municipal obligations. We buy municipal

average expected duration of the portfolio securities will be from one to five
years.

                    Mary Gail Walton (since 2/97)

INVESTMENT OBJECTIVE

     The National Tax-Free Fund seeks to provide investors with income exempt
from federal income tax.

INVESTMENT POLICIES

     We actively manage a portfolio of municipal obligations. We buy municipal
obligations of any maturity length. The portfolio's weighted average maturity
will vary depending on market conditions, economic conditions including interest
rates, the differences in yields between obligations of different maturity
lengths and other factors. There is no required range for the portfolio's dollar
weighted average maturity. Generally speaking, we will attempt to capture
greater total return by increasing maturity when we expect interest rates to
decline, and attempt to preserve capital by shortening maturity when interest
rates are expected to increase.

PORTFOLIO HOLDINGS

Under normal market conditions, we invest:
 .    at least 80% of our assets in municipal obligations that pay interest
     exempt from federal income tax;
 .    in municipal obligations rated in the three highest credit categories by
     nationally recognized credit rating organizations; or
 .    in municipal obligations rated in the fourth highest category if enough
     suitable investments in the three highest categories cannot be found.
We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interest of shareholders to
do so.

IMPORTANT RISK FACTORS

For general information on risk, please see page ___.

     The Fund is considered non-diversified according to the 1940 Investment
Company Act. Default by a single security in the portfolio may have a greater
negative affect than a similar default in a diversified portfolio.
 
ADDITIONAL FUND FACTS

     Distribution income earned may be subject to the federal alternative
minimum tax.

INVESTMENT OBJECTIVE

     The Oregon Tax-Free Fund seeks to provide investors with a high level of
income exempt from federal income tax and Oregon personal income tax.

INVESTMENT POLICIES

     We actively manage a portfolio of municipal obligations. We buy municipal
obligations of any maturity length. The portfolio's weighted average maturity
will vary depending on market conditions, economic conditions including interest
rates, the differences in yields between obligations of different maturity
lengths and other factors. There is no required range for the portfolio's dollar
weighted average maturity.  Generally speaking, we will attempt to capture
greater total return by increasing maturity when we expect interest rates to
decline, and attempt to preserve capital by shortening maturity when interest
rates are expected to increase.

PORTFOLIO HOLDINGS

Under normal market conditions, we invest:
 .    at least 80% of our assets in municipal obligations that pay interest
     exempt from federal income tax;
 .    at least 65% of our assets in municipal obligations that pay interest
     exempt from Oregon personal income tax;
 .    in municipal obligations rated in the three highest credit categories by
     nationally recognized credit rating organizations; or
 .    in municipal obligations rated in the fourth highest category if enough
     suitable investments in the three highest categories cannot be found.
We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interest of shareholders to
do so.

IMPORTANT RISK FACTORS

For general information on risk, please see page ___.

     The Fund is considered non-diversified according to the 1940 Investment
Company Act. The majority of the issuers of the securities in the portfolio are
located within Oregon. Non-diversified, geographically concentrated Funds are
riskier than similar Funds that are diversified or spread their investments over
several geographical areas. Default by a single security in the portfolio may
have a greater negative affect than a similar default in a diversified
portfolio. Distribution income earned may be subject to the federal alternative
minimum tax.

ADDITIONAL FUND FACTS

     Distribution income earned may be subject to the federal alternative
minimum tax.

GENERAL RISK CONSIDERATIONS

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your tolerance and preferences. Some
risks are common to all the Stagecoach Funds. Chief among these risks is the
following:

 .    Unlike bank deposits such as CD's or savings accounts, mutual funds are NOT
     INSURED BY THE FDIC.
 .    We CANNOT GUARANTEE that we will meet our investment objectives.
 .    We do not guarantee the performance of a Fund, nor can we assure you that
     the market value of your investment will not decline. We will not "make
     good" any investment loss you may suffer, nor can anyone we contract with
     to perform certain functions, such as selling agents or investment
     advisors, offer or promise to make good any such losses.
 .    Share prices--and therefore the value of your investment--WILL INCREASE AND
     DECREASE with changes in the value of the underlying securities and other
     investments. This is referred to as volatility.
 .    Investing in any mutual fund, including the most conservative, involves
     RISK, INCLUDING THE POSSIBLE LOSS OF ANY MONEY YOU INVEST.
 .    No single Fund, by itself, constitutes a complete investment plan.

Some of our mutual funds invest in securities that involve particular kinds of
risk.

 .    Funds that invest in debt instruments, such as notes and bonds, are subject
     to CREDIT RISK. Credit risk is the chance that an issuer of a security will
     be unable to make interest payments or repay principal. Changes in the
     financial strength of an issuer or changes in the credit rating of a
     security may affect its value.

 .    Funds that invest in debt instruments, such as notes and bonds, are subject
     to INTEREST-RATE RISK. Interest-rate risk is the possibility that interest
     rates may increase and reduce the resale value of securities in a Fund's
     portfolio. Debt instruments with longer maturities are generally more
     sensitive to interest rate changes than those with shorter maturities.
     Changes in market interest rates do not affect the rate payable on debt
     instruments held in a Fund, unless the instrument has adjustable or
     variable rate features. Changes in market interest rates may also extend or
     shorten the duration of certain types of instruments, such as asset-backed
     securities, thereby affecting their value and the return on your
     investment.

We may invest a portion of our assets in U.S. Government obligations. It is
important to recognize that the U.S. Government does not guarantee the market
value or current yield of those obligations. Not all U.S. Government obligations
are backed by the full faith and credit of the U.S. Treasury, and the U.S.
Government's guarantee does not extend to the Fund itself.

We may also use certain derivative instruments such as options or futures
contracts. The term "derivatives" covers a wide number of investments, but in
general it refers to any financial instrument whose value is derived, at least
in part, from the price of another security or a specified index, asset or rate.
Some derivatives may be more sensitive to interest rate changes or market moves,
and some may be susceptible to changes in yields or values due to their
structure or contract terms.

What follows is a general list of the types of risks that may affect a given
Fund and a table showing some of the additional investment practices that each
Fund may use. Additional information about these practices is available in the
Statement of Additional Information.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule. If an issuer does default, the
affected security could lose all of its value, or be renegotiated at a lower
interest rate. Affected securities might also lose liquidity.  Credit risk also
includes the risk that a party in a transaction may not be able to complete the
transaction as agreed

Currency Risk--The risk that a change in the exchange rate between U.S. dollars
and a foreign currency may reduce the value of investment made in a security
denominated in that foreign currency.

ORGANIZATION AND MANAGEMENT OF THE FUNDS

A number of different companies and divisions perform the various tasks that are
required for a mutual fund company. This section shows how the Funds are
organized, who performs which of the various roles and what compensation they
receive. Further information is available in the Statement of Additional
Information for each Fund.

ABOUT STAGECOACH

Each Fund is one of 32 of the Stagecoach Funds, Inc. Stagecoach was organized on
September 9, 1991 as a Maryland Corporation.

The Board of Directors of Stagecoach supervises the Funds' activities and
approves the selection of various companies hired to manage the Funds'
operation. Some of these service providers are described in the diagram below.
If the Board believes that it is in the best interests of the shareholders it
may make a change in one of these companies.

We do not hold annual shareholder meetings. We may hold special shareholder
meetings to ask shareholders to vote on items such as electing or removing board
members, amending fundamental investment strategies or policies or considering,
where applicable, matters affecting a Master Portfolio.

assets;

contemporaneously owns or has the right to acquire at no additional cost

activity in the same industry if, immediately after the purchase and as a result
thereof, the value of the Fund's investments in that industry would be 25% or
more of the current value of the Fund's total assets, 

                                       2

accordance with the Fund's investment program may be deemed to be an
underwriting;

     (7)  make investments for the purpose of exercising control or management;

     (8)  issue senior securities, except the Fund may borrow from banks up to
10% of the current value of its net assets for temporary purposes only in order

10% of the current value of Fund's net assets (but investments may not be
purchased by the Fund while any such outstanding borrowings exceed 5% of the
Fund's net assets);

     (9)  write, purchase or sell puts, calls, straddles, spreads, warrants,
options or any combination thereof, except that the Fund may purchase securities
with put rights in order to maintain liquidity and may invest up to 5% of its
net assets in warrants in accordance with its investment policies as stated
below; nor

     (10) purchase securities of any issuer (except securities issued or
guaranteed by the U.S. Government, its agencies and instrumentalities) if, as a
result, more than 5% of the value of the Fund's total assets would be invested

10% of the outstanding voting securities of such issuer.

     The Fund may make loans in accordance with its investment policies.

The Small Cap Fund may not:

thereof, the value of the Fund's 

                                       3
<PAGE>
 
investments in that industry would equal or exceed 25% of the current value of
the Fund's total assets, provided that there is no limitation with respect to
investments in securities issued or guaranteed by the United States Government,
its agencies or instrumentalities; and provided further, that the Fund may
invest all its assets in a diversified, open-end management investment company,
or a series thereof, with substantially the same investment objective, policies
and restrictions as the Fund, without regard to the limitations set forth in
this paragraph (1);

     (2)  purchase or sell real estate (other than securities secured by real

     (3)  purchase securities on margin (except for short-term credits necessary

     (4)  underwrite securities of other issuers, except to the extent that the
purchase of permitted investments directly from the issuer thereof or from an
underwriter for an issuer and the later disposition of such securities in
accordance with the Fund's investment program may be deemed to be an
underwriting; and provided further, that the purchase by the Fund of securities
issued by a diversified, open-end management investment company, or a series
thereof, with substantially the same investment objective, policies and
restrictions as the Fund shall not constitute an underwriting for purposes of
this paragraph (4);

     (5)  make investments for the purpose of exercising control or management;

purchased while any such outstanding borrowings exceed 5% of its net assets);

     (7)  make loans of portfolio securities having a value that exceeds 33 1/3%

its total assets would be invested in the securities of any one issuer or, with
respect to 100% of its total assets, the Fund's ownership would be more than 10%

invest all its assets in a diversified, open-end management investment company,
or a series thereof, with 

                                       4
<PAGE>
 
substantially the same investment objective, policies and restrictions as such
Fund, without regard to the limitations set forth in this paragraph (8).

     Non-Fundamental Investment Policies
     -----------------------------------

     Each Fund has adopted the following non-fundamental policies which may be
changed by a vote of a majority of the Directors of the Company or at any time
without approval of such Fund's shareholders.

     (1)  Each Fund may invest in shares of other open-end management investment
companies, subject to the limitations of Section 12(d)(1) of the 1940 Act.
Under the 1940 Act, a Fund's investment in such securities currently is limited
to , subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5%  of such Fund's net assets with respect to any one
investment company, and (iii) 10% of such Fund's net assets in the aggregate.
Other investment companies in which the Funds invest can be expected to charge
fees for operating expenses, such as investment advisory and administration
fees, that would be in addition to those charged by a Fund.

     (2)  Each Fund may not invest more than 15% of the Fund's net assets in
illiquid securities.  For this purpose, illiquid securities include, among
others, (a) securities that are illiquid by virtue of the absence of a readily
available market or legal or contractual restrictions on resale, (b) fixed time
deposits that are subject to withdrawal penalties and that have maturities of
more than seven days, and (c) repurchase agreements not terminable within seven
days.

     (3)  Each Fund may invest up to 25% of its net assets in securities of
foreign governmental and foreign private issuers that are denominated in and pay
interest in U.S. dollars.

     (4)  Each Fund may lend securities from its portfolio to brokers, dealers
and financial institutions, in amounts not to exceed (in the aggregate) one-
third of the Fund's total assets. Any such loans of portfolio securities will be
fully collateralized based on values that are marked to market daily. The Fund
will not enter into any portfolio security lending arrangement having a duration
of longer than one year.

                   ADDITIONAL PERMITTED INVESTMENT ACTIVITIES

     Set forth below are descriptions of certain investments and additional
investment policies for the Funds.

     Bank Obligations
     ----------------

     The Funds may invest in bank obligations, including certificates of
deposit, time deposits, bankers' acceptances and other short-term obligations of
domestic banks, foreign subsidiaries of domestic banks, foreign branches of
domestic banks, and domestic and foreign branches of foreign banks, domestic
savings and loan associations and other banking institutions. With respect to
such securities issued by foreign branches of domestic banks, foreign
subsidiaries of 

                                       5
<PAGE>
 
domestic banks, and domestic and foreign branches of foreign banks, a Fund may
be subject to additional investment risks that are different in some respects
from those incurred by a fund which invests only in debt obligations of U.S.
domestic issuers. Such risks include possible future political and economic
developments, the possible imposition of foreign withholding taxes on interest
income payable on the securities, the possible establishment of exchange
controls or the adoption of other foreign governmental restrictions which might
adversely affect the payment of principal and interest on these securities and
the possible seizure or nationalization of foreign deposits. In addition,
foreign branches of U.S. banks and foreign banks may be subject to less
stringent reserve requirements and to different accounting, auditing, reporting
and recordkeeping standards than those applicable to domestic branches of U.S.
banks.

    Certificates of deposit are negotiable certificates evidencing the
obligation of a bank to repay funds deposited with it for a specified period of
time.

    Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time at a stated interest rate.  Time
deposits which may be held by a Fund will not benefit from insurance from the
Bank Insurance Fund or the Savings Association Insurance Fund administered by
the Federal Deposit Insurance Corporation.  Bankers' acceptances are credit
instruments evidencing the obligation of a bank 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 face amount of the instrument upon maturity.  The other short-
term obligations may include uninsured, direct obligations, bearing fixed,
floating- or variable-interest rates.

    Commercial Paper
    ----------------

    The Funds may invest in commercial paper (including variable amount master
demand notes) which refers to short-term, unsecured promissory notes issued by
corporations to finance short-term credit needs. Commercial paper is usually
sold on a discount basis and has a maturity at the time of issuance not
exceeding nine months. Variable amount master demand notes are demand
obligations which permit the investment of fluctuating amounts at varying market
rates of interest pursuant to arrangements between the issuer and a commercial
bank acting as agent for the payee of such notes whereby both parties have the
right to vary the amount of the outstanding indebtedness on the notes.
Investments by the Funds in commercial paper (including variable rate demand
notes and variable rate master demand notes issued by domestic and foreign bank
holding companies, corporations and financial institutions, as well as similar
instruments issued by government agencies and instrumentalities) will consist of
issues that are rated in ONE OF THE TWO HIGHEST RATING CATEGORIES BY A NRSRO.
Commercial paper may include variable- and floating-rate instruments.

    Convertible Securities (Lower Rated Securities)
    -----------------------------------------------

    The Funds may invest in convertible securities that are not rated in one of
the four highest rating categories by a NRSRO. The yields on such lower rated
securities, which includes securities also known as junk bonds, generally are
higher than the yields available on higher-rated securities. However,
investments in lower rated securities and comparable unrated securities
generally involve greater volatility of price and risk of loss of income and
principal,

                                       6
<PAGE>
 
including the probability of default by or bankruptcy of the issuers of such
securities. Lower rated securities and comparable unrated securities (a) will
likely have some quality and protective characteristics that, in the judgment of
the rating organization, are outweighed by large uncertainties or major risk
exposures to adverse conditions and (b) are predominantly speculative with
respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. Accordingly, it is possible that
these types of factors could, in certain instances, reduce the value of
securities held in a Fund's portfolio, with a commensurate effect on the value
of the Fund's shares. Therefore, an investment in the Fund should not be
considered as a complete investment program and may not be appropriate for all
investors.

    While the market values of lower rated securities and comparable unrated
securities tend to react less to fluctuations in interest rate levels than the
market values of higher-rated securities, the market values of certain lower
rated securities and comparable unrated securities also tend to be more
sensitive to individual corporate developments and changes in economic
conditions than higher-rated securities.  In addition, lower rated securities
and comparable unrated securities generally present a higher degree of credit
risk.  Issuers of lower rated securities and comparable unrated securities often
are highly leveraged and may not have more traditional methods of financing
available to them so that their ability to service their debt obligations during
an economic downturn or during sustained periods of rising interest rates may be
impaired.  The risk of loss due to default by such issuers is significantly
greater because lower rated securities and comparable unrated securities
generally are unsecured and frequently are subordinated to the prior payment of
senior indebtedness.  The Fund may incur additional expenses to the extent that
it is required to seek recovery upon a default in the payment of principal or
interest on its portfolio holdings.  The existence of limited markets for lower
rated securities and comparable unrated securities may diminish the Fund's
ability to (a) obtain accurate market quotations for purposes of valuing such
securities and calculating its net asset value and (b) sell the securities at
fair value either to meet redemption requests or to respond to changes in the
economy or in financial markets.

    Certain lower rated debt securities and comparable unrated securities
frequently have call or buy-back features that permit their issuers to call or
repurchase the securities from their holders, such as the Fund.  If an issuer
exercises these rights during periods of declining interest rates, the Fund may
have to replace the security with a lower yielding security, thus resulting in a
decreased return to the Fund.

    The market for certain lower rated securities and comparable unrated
securities is relatively new and has not weathered a major economic recession.
The effect that such a recession might have on such securities is not known.
Any such recession, however, could disrupt severely the market for such
securities and adversely affect the value of such securities.  Any such economic
downturn also could adversely affect the ability of the issuers of such
securities to repay principal and pay interest thereon.

    The Funds may invest in convertible securities that provide current income
and are issued by companies with the characteristics described above for each
Fund and that have a strong earnings and credit record. The Funds may purchase
convertible securities that are fixed-income 

                                       7
<PAGE>
 
debt securities or preferred stocks, and which may be converted at a stated
price within a specified period of time into a certain quantity of the common
stock of the same issuer. Convertible securities, while usually subordinate to
similar nonconvertible securities, are senior to common stocks in an issuer's
capital structure. Convertible securities offer flexibility by providing the
investor with a steady income stream (which generally yield a lower amount than
similar nonconvertible securities and a higher amount than common stocks) as
well as the opportunity to take advantage of increases in the price of the
issuer's common stock through the conversion feature. Fluctuations in the
convertible security's price can reflect changes in the market value of the
common stock or changes in market interest rates. At most, 5% of each Fund's net
assets will be invested, at the time of purchase, in convertible securities that
are not rated in the four highest rating categories by one or more NRSROs, such
as Moody's or S&P, or unrated but determined by the Adviser to be of comparable
quality.

    Corporate Reorganizations
    -------------------------

    The Funds may invest in securities for which a tender or exchange offer has
been made or announced, and in securities of companies for which a merger,
consolidation, liquidation or similar reorganization proposal has been announced
if, in the judgment of Wells Fargo Bank, there is a reasonable prospect of
capital appreciation significantly greater than the added portfolio turnover
expenses inherent in the short term nature of such transactions. The principal
risk associated with such investments is that such offers or proposals may not
be consummated within the time and under the terms contemplated at the time of
the investment, in which case, unless such offers or proposals are replaced by
equivalent or increased offers or proposals which are consummated, the Funds may
sustain a loss.

    Custodial Receipts for Treasury Securities
    ------------------------------------------

    The Funds may purchase participations in trusts that hold U.S. Treasury
securities (such as TIGRs and CATS) or other obligations where the trust
participations evidence ownership in either the future interest payments or the
future principal payments on the obligations. These participations are normally
issued at a discount to their "face value," and can exhibit greater price
volatility than ordinary debt securities because of the way in which their
principal and interest are returned to investors. Investments by a Fund in such
participations will not exceed 5% of the value of that Fund's total assets.

    Emerging Markets
    ----------------

    The Small Cap Fund may invest up to 15% of its assets in equity securities
of companies in "emerging markets." The Fund considers countries with emerging
markets to include the following: (i) countries with an emerging stock market as
defined by the International Finance Corporation; (ii) countries with low- to
middle-income economies according to the International Bank for Reconstruction
and Development (more commonly referred to as the World Bank); and (iii)
countries listed in World Bank publications as developing. The adviser may
invest in those emerging markets that have a relatively low gross national
product per capita, compared to the world's major economies, and which exhibit
potential for rapid economic growth. The adviser 

                                       8
<PAGE>
 
believes that investment in equity securities of emerging market issuers offers
significant potential for long-term capital appreciation.

     Equity securities of emerging market issuers may include common stock,
preferred stocks (including convertible preferred stocks) and warrants; bonds,
notes and debentures convertible into common or preferred stock; equity
interests in foreign investment funds or trusts and real estate investment trust
securities.  The Small Cap Fund may invest in American Depositary Receipts
("ADRs"), Canadian Depositary Receipts ("CDRs"), European Depositary Receipts
("EDRs"), Global Depositary Receipts ("GDRs") and International Depositary
Receipts ("IDRs") of such issuers.

     Emerging market countries include, but are not limited to: Argentina,
Brazil, Chile, China, the Czech Republic, Columbia, Ecuador, Greece, Hong Kong,
Indonesia, India, Malaysia, Mexico, the Philippines, Poland, Portugal, Peru,
Russia, Singapore, South Africa, Thailand, Taiwan and Turkey. A company is
considered in a country, market or region if it conducts its principal business
activities there, namely, if it derives a significant portion (at least 50%) of
its revenues or profits from goods produced or sold, investments made, or
services performed therein or has at least 50% of its assets situated in such
country, market or region.

     There are special risks involved in investing in emerging-market countries.
Many investments in emerging markets can be considered speculative, and their
prices can be much more volatile than in the more developed nations of the
world. This difference reflects the greater uncertainties of investing in less
established markets and economies. The financial markets of emerging markets
countries are generally less well capitalized and thus securities of issuers
based in such countries may be less liquid.  Most are heavily dependent on
international trade, and some are especially vulnerable to recessions in other
countries. Many of these countries are also sensitive to world commodity prices.
Some countries may still have obsolete financial systems, economic problems or
archaic legal systems. In addition, many of these nations are experiencing
political and social uncertainties.

     Floating- and Variable-Rate Obligations
     ---------------------------------------

     The Funds may purchase floating- and  variable-rate obligations.  Each Fund
may purchase floating- and variable-rate demand notes and bonds.  Variable-rate
demand notes include master demand notes that are obligations that permit a Fund
to invest fluctuating amounts, which may change daily without penalty, pursuant
to direct arrangements between the Fund, as lender, and the borrower.  The
interest rates on these notes may fluctuate from time to time.  The issuer of
such obligations ordinarily has a corresponding right, after a given period, to
prepay in its discretion the outstanding principal amount of the obligations
plus accrued interest upon a specified number of days' notice to the holders of
such obligations.  The interest rate on a floating-rate demand obligation is
based on a known lending rate, such as a bank's prime rate, and is adjusted
automatically each time such rate is adjusted.  The interest rate on a variable-
rate demand obligation is adjusted automatically at specified intervals.
Frequently, such obligations are secured by letters of credit or other credit
support arrangements provided by banks.  Because these obligations are direct
lending arrangements between the lender and borrower, it is not 

                                       9
<PAGE>
 
contemplated that such instruments generally will be traded, and there generally
is no established secondary market for these obligations, although they are
redeemable at face value. Accordingly, where these obligations are not secured
by letters of credit or other credit support arrangements, a Fund's right to
redeem is dependent on the ability of the borrower to pay principal and interest
on demand. Such obligations frequently are not rated by credit rating agencies
and each Fund may invest in obligations which are not so rated only if Wells
Fargo Bank determines that at the time of investment the obligations are of
comparable quality to the other obligations in which such Fund may invest. Wells
Fargo Bank, on behalf of each Fund, considers on an ongoing basis the
creditworthiness of the issuers of the floating- and variable-rate demand
obligations in such Fund's portfolio. No Fund will invest more than 15% of the
value of its total net assets in floating- or variable-rate demand obligations
whose demand feature is not exercisable within seven days. Such obligations may
be treated as liquid, provided that an active secondary market exists. Floating-
and variable-rate instruments are subject to interest-rate risk and credit risk.

    THE FLOATING- AND VARIABLE-RATE INSTRUMENTS THAT THE FUNDS MAY PURCHASE
INCLUDE CERTIFICATES OF PARTICIPATION IN SUCH INSTRUMENTS.

    The Balanced and Equity Value Funds may also hold floating- and variable-
rate instruments that have interest rates that re-set inversely to changing
current market rates and/or have embedded interest rate floors and caps that
require the issuer to pay an adjusted interest rate if market rates fall below
or rise above a specified rate. These instruments represent relatively recent
innovations in the bond markets, and the trading market for these instruments is
less developed than the markets for traditional types of debt instruments. It is
uncertain how these instruments will perform under different economic and
interest-rate scenarios. The market value of these instruments may be more
volatile than other types of debt instruments and may present greater potential
for capital-gain or loss. In some cases, it may be difficult to determine the
fair value of a structured or derivative instrument because of a lack of
reliable objective information and an established secondary market for some
instruments may not exist.

    Foreign Obligations
    -------------------

    The Balanced, Equity Value, Growth and Small Cap Funds may invest in foreign
securities through American Depositary Receipts ("ADRs"), Canadian Depositary
Receipts ("CDRs"), European Depositary Receipts ("EDRs"), International
Depositary Receipts ("IDRs") and Global Depositary Receipts ("GDRs") or other
similar securities convertible into securities of foreign issuers. These
securities may not necessarily be denominated in the same currency as the
securities into which they may be converted. ADRs (sponsored or unsponsored) are
receipts typically issued by a U.S. bank or trust company and traded on a U.S.
stock exchange, and CDRs are receipts typically issued by a Canadian bank or
trust company that evidence ownership of underlying foreign securities. Issuers
of unsponsored ADRs are not contractually obligated to disclose material
information in the U.S. and, therefore, such information may not correlate to
the market value of the unsponsored ADR. EDRs and IDRs are receipts typically
issued by European banks and trust companies, and GDRs are receipts issued by
either a U.S. or non-U.S. banking institution, that evidence ownership of the
underlying foreign securities. Generally, ADRs in registered form are 

                                      10
<PAGE>
 
designed for use in U.S. securities markets and EDRs and IDRs in bearer form are
designed primarily for use in Europe. The Growth Fund currently does not intend
to invest more than 10% of its assets in foreign obligations. Each Fund may not
invest 25% or more of its assets in foreign obligations.

    Investments in foreign securities involve certain considerations that are
not typically associated with investing in domestic securities. There may be
less publicly available information about a foreign issuer than about a domestic
issuer. Foreign issuers also are not generally subject to the same accounting,
auditing and financial reporting standards or governmental supervision as
domestic issuers. In addition, with respect to certain foreign countries, taxes
may be withheld at the source under foreign tax laws, and there is a possibility
of expropriation or confiscatory taxation, political, social and monetary
instability or diplomatic developments that could adversely affect investments
in, the liquidity of, and the ability to enforce contractual obligations with
respect to, securities of issuers located in those countries.

    Foreign Currency Transactions
    -----------------------------

    The Equity Value and Balanced Funds may enter into foreign currency exchange
contracts in order to protect against uncertainty in the level of future foreign
exchange rates. A forward foreign currency exchange contract involves an
obligation to purchase or sell a specific currency at a future date, which may
be any fixed number of days from the date of the contract agreed upon by the
parties, at a price set at the time of the contract. These contracts are entered
into the interbank market conducted between currency traders (usually large
commercial banks) and their customers. Forward foreign currency exchange
contracts may be bought or sold to protect a Fund against a possible loss
resulting from an adverse change in the relationship between foreign currencies
and the U.S. dollar, or between foreign currencies. Although such contracts are
intended to minimize the risk of loss due to a decline in the value of the
hedged currency, at the same time, they tend to limit any potential gain which
might result should the value of such currency increase.

    Because the Balanced and Equity Value Funds may invest in securities
denominated in currencies other than the U.S. dollar and may temporarily hold
funds in bank deposits or other money market investments denominated in foreign
currencies, they may be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rate between such currencies and the
dollar. Changes in foreign currency exchange rates influence values within a
Fund from the perspective of U.S. investors. Changes in foreign currency
exchange rates may also affect the value of dividends and interest earned, gains
and losses realized on the sale of securities, and any net investment income and
gains to be distributed to shareholders by a Fund. The rate of exchange between
the U.S. dollar and other currencies is determined by the forces of supply and
demand in the foreign exchange markets. These forces are affected by the
international balance of payments and other economic and financial conditions,
government intervention, speculation and other factors.

    Investments in foreign securities also involve certain inherent risks, such
as political or economic instability of the issuer or the country of issue, the
difficulty of predicting international trade patterns and the possibility of
imposition of exchange controls. Such securities may also be 

                                      11
<PAGE>
 
subject to greater fluctuations in price than securities of domestic
corporations. In addition, there may be less publicly available information
about a foreign company than about a domestic company. Foreign companies
generally are not subject to uniform accounting, auditing and financial
reporting standards comparable to those applicable to domestic companies.
Investments in foreign securities and forward contracts may also be subject to
withholding and other taxes imposed by foreign governments. With respect to
certain foreign countries, there is also a possibility of expropriation or
confiscatory taxation, or diplomatic developments which could affect investments
in those countries.

    Forward Commitments, When-Issued Purchases and Delayed-Delivery Transactions
    ----------------------------------------------------------------------------

    Each Fund may purchase or sell securities on a when-issued or delayed-
delivery basis and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time.  Securities purchased
or sold on a when-issued, delayed-delivery or forward commitment basis involve a
risk of loss if the value of the security to be purchased declines, or the value
of the security to be sold increases, before the settlement date.  Although each
Fund will generally purchase securities with the intention of acquiring them, a
Fund may dispose of securities purchased on a when-issued, delayed-delivery or a
forward commitment basis before settlement when deemed appropriate by the
adviser.  Securities purchased on a when-issued or forward commitment basis may
expose the relevant Fund to risk because they may experience such fluctuations
prior to their actual delivery.  Purchasing securities on a when-issued or
forward commitment basis can involve the additional risk that the yield
available in the market when the delivery takes place actually may be higher
than that obtained in the transaction itself.

    Each Fund will segregate cash, U.S. Government obligations or other high-
quality debt instruments in an amount at least equal in value to the Fund's
commitments to purchase when-issued securities.  If the value of these assets
declines, the Fund will segregate additional liquid assets on a daily basis so
that the value of the segregated assets is equal to the amount of such
commitments.

    Loans of Portfolio Securities
    -----------------------------

    Each Fund may lend their portfolio securities to brokers, dealers and
financial institutions, provided: (1) the loan is secured continuously by
collateral consisting of U.S. Government securities or cash or letters of credit
maintained on a daily marked-to-market basis in an amount at least equal to the
current market value of the securities loaned; (2) the Fund may at any time call
the loan and obtain the return of the securities loaned within five business
days; (3) the Fund will receive any interest or dividends paid on the loaned
securities; and (4) the aggregate market value of securities loaned will not at
any time exceed one third of the total assets of the Fund.

    A Fund will earn income for lending its securities because cash collateral
pursuant to these loans will be invested in short-term money market instruments.
In connection with lending securities, a Fund may pay reasonable finders,
administrative and custodial fees.  A Fund will not enter into any security
lending arrangement having a duration longer than one year.  Loans of securities
involve a risk that the borrower may fail to return the securities or may fail
to provide 

                                      12
<PAGE>
 
additional collateral. In either case, a Fund could experience delays in
recovering securities or collateral or could lose all or part of the value of
the loaned securities. When a Fund lends its securities, it continues to receive
interest or dividends on the securities loaned and may simultaneously earn
interest on the collateral received from the borrower or from the investment of
cash collateral in readily marketable, high-quality, short-term obligations.
Although voting rights, or rights to consent, attendant to securities on loan
pass to the borrower, such loans may be called at any time and will be called so
that the securities may be voted by a Fund if a material event affecting the
investment is to occur. A Fund may pay a portion of the interest or fees earned
from securities lending to a borrower or placing broker. Borrowers and placing
brokers may not be affiliated, directly or indirectly, with Wells Fargo Bank,
Stephens Inc. or any of their affiliates.

     Money Market Instruments and Temporary Investments
     --------------------------------------------------

     The Funds may invest in the following types of high quality money market
instruments that have remaining maturities not exceeding one year: (i) U.S.
Government obligations; (ii) negotiable certificates of deposit, bankers'
acceptances and fixed time deposits and other obligations of domestic banks
(including foreign branches) that have more than $1 billion in total assets at
the time of investment and are members of the Federal Reserve System or are
examined by the Comptroller of the Currency or whose deposits are insured by the
FDIC; (iii) commercial paper rated at the date of purchase "Prime-1" by Moody's
or "A-1" or "A-1--" by S&P, or, if unrated, of comparable quality as determined
by Wells Fargo Bank, as investment adviser; and (iv) repurchase agreements.  The
Funds also may invest in short-term U.S. dollar-denominated obligations of
foreign banks (including U.S. branches) that at the time of investment: (i) have
more than $10 billion, or the equivalent in other currencies, in total assets;
(ii) are among the 75 largest foreign banks in the world as determined on the
basis of assets; (iii) have branches or agencies in the United States; and (iv)
in the opinion of Wells Fargo Bank, as investment adviser, are of comparable
quality to obligations of U.S. banks which may be purchased by the Funds.

     Letters of Credit.  Certain of the debt obligations (including certificates
of participation, commercial paper and other short-term obligations) which the
Funds may purchase may be backed by an unconditional and irrevocable letter of
credit of a bank, savings and loan association or insurance company which
assumes the obligation for payment of principal and interest in the event of
default by the issuer.  Only banks, savings and loan associations and insurance
companies which, in the opinion of Wells Fargo Bank, are of comparable quality
to issuers of other permitted investments of the Fund may be used for letter of
credit-backed investments.

     Borrowing and Reverse Repurchase Agreements.  The BALANCED AND EQUITY VALUE
Funds each intends to limit its borrowings (including reverse repurchase
agreements) during the current fiscal year to not more than 10% of its net
assets.  At the time a Fund enters into a reverse repurchase agreement (an
agreement under which the Fund sells portfolio securities and agrees to
repurchase them at an agreed-upon date and price), it will place in a segregated
custodial account liquid assets such as U.S. Government securities or other
liquid high-grade debt securities having a value equal to or greater than the
repurchase price (including accrued interest) and will subsequently monitor the
account to ensure that such value is maintained. Reverse repurchase 

                                      13
<PAGE>
 
agreements involve the risk that the market value of the securities sold by a
Fund may decline below the price at which the Fund is obligated to repurchase
the securities. Reverse repurchase agreements are considered to be borrowings
under the 1940 Act.

    Repurchase Agreements.  A Fund may enter into repurchase agreements, wherein
the seller of a security to the Fund agrees to repurchase that security from the
Fund at a mutually agreed upon time and price.  A Fund may enter into repurchase
agreements only with respect to securities that could otherwise be purchased by
the Fund.  All repurchase agreements will be fully collateralized at 102% based
on values that are marked to market daily.  The maturities of the underlying
securities in a repurchase agreement transaction may be greater than twelve
months, although the maximum term of a repurchase agreement will always be less
than twelve months.  If the seller defaults and the value of the underlying
securities has declined, a Fund may incur a loss.  In addition, if bankruptcy
proceedings are commenced with respect to the seller of the security, the Fund's
disposition of the security may be delayed or limited.

    Each Fund may not enter into a repurchase agreement with a maturity of more
than seven days, if, as a result, more than 15% of the market value of such
Fund's total net assets would be invested in repurchase agreements with
maturities of more than seven days, restricted securities and illiquid
securities.  A Fund will only enter into repurchase agreements with primary
broker/dealers and commercial banks that meet guidelines established by the
Board of Directors and that are not affiliated with the investment adviser.  The
Funds may participate in pooled repurchase agreement transactions with other
funds advised by Wells Fargo Bank.

    Mortgage-Related Securities
    ---------------------------

    The Balanced Fund may invest in mortgage-related securities. Mortgage pass-
through securities are securities representing interests in "pools" of mortgages
in which payments of both interest and principal on the securities are made
monthly, in effect "passing through" monthly payments made by the individual
borrowers on the residential mortgage loans which underlie the securities (net
of fees paid to the issuer or guarantor of the securities). Early repayment of
principal on mortgage pass-through securities (arising from prepayments of
principal due to sale of the underlying property, refinancing, or foreclosure,
net of fees and costs which may be incurred) may expose the Fund to a lower rate
of return upon reinvestment of principal. Also, if a security subject to
prepayment has been purchased at a premium, in the event of prepayment the value
of the premium would be lost. Like other fixed-income securities, when interest
rates rise, the value of a mortgage-related security generally will decline;
however, when interest rates decline, the value of mortgage-related securities
with prepayment features may not increase as much as other fixed-income
securities. Payment of principal and interest on some mortgage pass-through
securities (but not the market value of the securities themselves) may be
guaranteed by the full faith and credit of the U.S. Government or its agencies
or instrumentalities. Mortgage pass-through securities created by non-government
issuers (such as commercial banks, savings and loan institutions, private
mortgage insurance companies, mortgage bankers and other secondary market
issuers) may be supported by various forms of insurance or guarantees, including
individual loan, title, pool and hazard insurance, and letters of credit, which
may be issued by governmental entities, private insurers or the mortgage
poolers. The Balanced Fund may also invest in investment grade 

                                      14
<PAGE>
 
Collateralized Mortgage Obligations ("CMOs"). CMOs may be collateralized by
whole mortgage loans but are more typically collateralized by portfolios of
mortgage pass-through securities guaranteed by GNMA, FHLMC or FNMA. CMOs are
structured into multiple classes, with each class bearing a different stated
maturity. Payments of principal, including prepayments, are first returned to
investors holding the shortest maturity class; investors holding the longer
maturity classes receive principal only after the first class has been retired.
As new types of mortgage-related securities are developed and offered to
investors, the Adviser will, consistent with a Fund's investment objective,
policies and quality standards, consider making investments in such new types of
mortgage-related securities.

    There are risks inherent in the purchase of mortgage-related securities. For
example, these securities are subject to a risk that default in payment will
occur on the underlying mortgages. In addition to default risk, these securities
are subject to the risk that prepayment on the underlying mortgages will occur
earlier or later or at a lessor or greater rate than expected. To the extent
that adviser's assumptions about prepayments are inaccurate, these securities
may expose the Funds, to significantly greater market risks than expected.

    Other Asset-Backed Securities
    -----------------------------

    The Balanced, Equity Value and Growth Funds may purchase asset-backed
securities unrelated to mortgage loans. These asset-backed securities may
consist of undivided fractional interests in pools of consumer loans or
receivables held in trust. Examples include certificates for automobile
receivables (CARS) and credit card receivables (CARDS). Payments of principal
and interest on these asset-backed securities are "passed through" on a monthly
or other periodic basis to certificate holders and are typically supported by
some form of credit enhancement, such as a letter of credit, surety bond,
limited guaranty, or subordination. The extent of credit enhancement varies, but
usually amounts to only a fraction of the asset-backed security's par value
until exhausted. Ultimately, asset-backed securities are dependent upon payment
of the consumer loans or receivables by individuals, and the certificate holder
frequently has no recourse to the entity that originated the loans or
receivables. The actual maturity and realized yield will vary based upon the
prepayment experience of the underlying asset pool and prevailing interest rates
at the time of prepayment. Asset-backed securities are relatively new
instruments and may be subject to greater risk of default during periods of
economic downturn than other instruments. Also, the secondary market for certain
asset-backed securities may not be as liquid as the market for other types of
securities, which could result in a Fund experiencing difficulty in valuing or
liquidating such securities.

    Municipal Obligations
    ---------------------

    Municipal obligations in which the Balanced and Equity Value Funds may
invest subject to the investment policies disclosed in the Prospectus include
debt obligations issued by governmental entities to obtain funds for various
public purposes, including the construction of a wide range of public
facilities, the refunding of outstanding obligations, the payment of general
operating expenses and the extension of loans to public institutions and
facilities.

                                      15
<PAGE>
 
    The two principal classifications of municipal obligations that may be held
by the Balanced and Equity Value Funds are "general obligation" securities and
"revenue" securities. General obligation securities are secured by the issuer's
pledge of its full faith, credit and taxing power for the payment of principal
and interest. Revenue securities are payable only from the revenues derived from
a particular facility or class of facilities or, in some cases, from the
proceeds of a special excise tax or other specific revenue source such as the
issuer of the facility being financed.  A Fund's portfolio may also include
"moral obligation" securities, which are issued normally by special purpose
public authorities. If the issuer of moral obligation securities is unable to
meet its debt service obligations from current revenues, it may draw on a
reserve fund, the restoration of which is a moral commitment but not a legal
obligation of the state or municipality that created the issuer.

    There are, of course, variations in the quality of municipal obligations
both within a particular classification and between classifications, and the
yields on municipal obligations depend upon a variety of factors, including
general money market conditions, the financial condition of the issuer, general
conditions of the municipal bond market, the size of a particular offering, the
maturity of the obligation and the rating of the issue.

    Private activity bonds are issued to obtain funds to provide privately
operated housing facilities, pollution control facilities, convention or trade
show facilities, mass transit, airport, port or parking facilities and certain
local facilities for water supply, gas, electricity or sewage or solid waste
disposal.  State and local governments are authorized in most states to issue
private activity bonds for such purposes in order to encourage corporations to
locate within their communities. Private activity bonds are in most cases
revenue securities and are not payable from the unrestricted revenues of the
issuer.  Private activity bonds include industrial development bonds, which  are
a specific type of revenue bond backed by the credit and security of a private
user.   The credit quality of such bonds is usually directly related to the
credit standing of the corporate user of the facility involved. Private activity
bonds issued by or on behalf of public authorities to finance various privately
operated facilities are considered municipal obligations if the interest
received thereon is exempt from federal income tax but nevertheless subject to
the federal alternative minimum tax.  Assessment bonds, wherein a specially
created district or project area levies a tax (generally on its taxable
property) to pay for an improvement or project may be considered a variant of
either category.  There are, of course, other variations in the types of
municipal bonds, both within a particular classification and between
classifications, depending on numerous factors.  Some or all of these bonds may
be considered "private activity bonds" for federal income tax purposes.

    THE FUNDS MAY INVEST IN MUNICIPAL LEASE OBLIGATIONS.  The adviser, under the
supervision of the Board, makes determinations concerning the liquidity of a
municipal lease obligation based on all relevant factors. These factors may
include, among others: (1) the frequency of trades and quotes for the
obligation; (2) the number of dealers willing to purchase or sell the security
and the number of other potential buyers; (3) the willingness of dealers to
undertake to make a market in the security; and (4) the nature of the
marketplace trades, including the time needed to dispose of the security, the
method of soliciting offers, and the mechanics of transfer. In addition, the
general credit quality of the municipality and the essentiality to the
municipality of the property covered by 

                                      16
<PAGE>
 
the lease may be considered. In evaluating the credit quality of a municipal
lease obligation, the factors to be considered might include: (1) whether the
lease can be canceled; (2) what assurance there is that the assets represented
by the lease can be sold; (3) the strength of the lessee's general credit (e.g.,
its debt, administrative, economic, and financial characteristics); (4) the
likelihood that the municipality will discontinue appropriating funding for the
leased property because the property is no longer deemed essential to the
operations of the municipality (e.g., the potential for an "event of the
nonappropriation"); and (5) the legal recourse in the event of failure to
appropriate.

    From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on municipal obligations. For example, under federal tax legislation
enacted in 1986, interest on certain private activity bonds must be included in
an investor's alternative minimum taxable income, and corporate investors must
treat all tax-exempt interest as an item of tax preference.

    Opinions relating to the validity of municipal obligations and to the
exemption of interest thereon from federal income tax are rendered by bond
counsel to the respective issuers at the time of issuance. Neither the Funds nor
the adviser will review the proceedings relating to the issuance of municipal
obligations or the basis for such opinions.

    Certain of the municipal obligations held by a Fund may be insured as to the
timely payment of principal and interest. The insurance policies usually are
obtained by the issuer of the municipal obligation at the time of its original
issuance. In the event that the issuer defaults on interest or principal
payment, the insurer will be notified and will be required to make payment to
the bondholders. There is, however, no guarantee that the insurer will meet its
obligations. In addition, such insurance does not protect against market
fluctuations caused by changes in interest rates and other factors.

    The values of outstanding municipal securities will vary as a result of
changing market evaluations of the ability of their issuers to meet the interest
and principal payments (i.e., credit risk).  Such values also will change in
                        - -                                                 
response to changes in the interest rates payable on new issues of municipal
securities (i.e., market risk).  Should such interest rates rise, the values of
            - -                                                                
outstanding securities, including those held in a Fund's portfolio, will decline
and (if purchased at par value) sell at a discount.  If interests rates fall,
the values of outstanding securities will generally increase and (if purchased
at par value) sell at a premium.  Changes in the value of municipal securities
held in the Fund's portfolio arising from these or other factors will cause
changes in the net asset value per share of the Fund.

    Options Trading
    ---------------

    The Balanced, Equity Value and Small Cap Funds may purchase or sell options
on individual securities or options on indices of securities as described below.
The purchaser of an option risks a total loss of the premium paid for the option
if the price of the underlying security does not increase or decrease
sufficiently to justify exercise. The seller of an option, on the other hand,
will recognize the premium as income if the option expires unrecognized but
foregoes any 

                                      17
<PAGE>
 
capital appreciation in excess of the exercise price in the case of a call
option and may be required to pay a price in excess of current market value in
the case of a put option.

    Call and Put Options on Specific Securities.  The Equity Value and Small Cap
Funds may invest in call and put options on a specific security.  Each of the
Balanced and Equity Value Funds may purchase put and call options listed on a
national securities exchange and issued by the Options Clearing Corporation in
an amount not exceeding 5% of its net assets.

    A call option gives the purchaser of the option the right to buy, and
obligates the writer to sell, an underlying security at the exercise price at
any time during the option period. Conversely, a put option gives the purchaser
of the option the right to sell, and obligates the writer to buy, an underlying
security at the exercise price at any time during the option period. Investments
by the Fund in off-exchange options will be treated as "illiquid" and therefore
subject to the Fund's policy of not investing more than 15% of its net assets in
illiquid securities.

    The Balanced, Equity Value and Small Cap Funds may write covered call option
contracts and secured put options as Wells Fargo Bank deems appropriate. A
covered call option is a call option for which the writer of the option owns the
security covered by the option. Covered call options written by a Fund expose
the Fund during the term of the option (i) to the possible loss of opportunity
to realize appreciation in the market price of the underlying security or (ii)
to possible loss caused by continued holding of a security which might otherwise
have been sold to protect against depreciation in the market price of the
security. If the Fund writes a secured put option, it assumes the risk of loss
should the market value of the underlying security decline below the exercise
price of the option. The aggregate value of the securities subject to options
written by the Fund will not exceed 25% of the value of the assets of the
Balanced or Equity Value Funds or 15% of the value of the assets of the Small
Cap Fund. The use of covered call options and securities put options will not be
a primary investment technique of the Fund, and they are expected to be used
infrequently. If the adviser is incorrect in its forecast of market value or
other factors when writing the foregoing options, the Fund would be in a worse
position than it would have been had the foregoing investment techniques not
been used.

    The Small Cap Fund may engage in unlisted over-the-counter options with
broker/dealers deemed creditworthy by the adviser. Closing transactions for such
options are usually effected directly with the same broker/dealer that effected
the original option transaction. The Fund bears the risk that the broker/dealer
will fail to meet its obligations. There is no assurance that a liquid secondary
trading market exists for closing out an unlisted option position. Furthermore,
unlisted options are not subject to the protections afforded purchasers of
listed options by the Options Clearing Corporation, which performs the
obligations of its members who fail to perform in connection with the purchase
or sale of options.

    Each Fund may buy put and call options and write covered call and secured
put options. Options trading is a highly specialized activity which entails
greater than ordinary investment risk. Options may be more volatile than the
underlying instruments, and therefore, on a percentage basis, an investment in
options may be subject to greater fluctuation than an investment in the
underlying 

                                      18
<PAGE>
 
instruments themselves. Purchasing options is a specialized investment technique
that entails a substantial risk of a complete loss of the amounts paid as
premiums to the writer of the option.

    The Funds may also write covered call and secured put options from time to
time as the adviser deems appropriate.  By writing a covered call option, a Fund
forgoes the opportunity to profit from an increase in the market of the
underlying security above the exercise price except insofar as the premium
represents such a profit, and it is not able to sell the underlying security
until the option expires or is exercised or the Fund effects a closing purchase
transaction by purchasing an option of the same series.  If a Fund writes a
secured put option, it assumes the risk of loss should the market value of the
underlying security decline below the exercise price of the option.  If the
adviser is incorrect in its forecast of market value or other factors when
writing the foregoing options, the Fund would be in a worse position than it
would have been had the foregoing investment techniques not been used.

    A call option for a particular security gives the purchaser of the option
the right to buy, and a writer the obligation to sell, the underlying security
at the stated exercise price at any time prior to the expiration of the option,
regardless of the market price of the security. The premium paid to the writer
is in consideration for undertaking the obligation under the option contract. A
put option for a particular security gives the purchaser the right to sell the
security at the stated exercise price at any time prior to the expiration date
of the option, regardless of the market price of the security. Options on
indices provide the holder with the right to make or receive a cash settlement
upon exercise of the option. With respect to options on indices, the amount of
the settlement equals the difference between the closing price of the index at
the time of exercise and the exercise price of the option expressed in dollars,
times a specified multiple.

    The Funds will write call options only if they are "covered." In the case of
a call option on a security or currency, the option is "covered" if a Fund owns
the instrument underlying the call or has an absolute and immediate right to
acquire that instrument without additional cash consideration (or, if additional
cash consideration is required, cash, U.S. Government securities or other liquid
high grade debt obligations, in such amount are held in a segregated account by
the Fund's custodian) upon conversion or exchange of other securities held by
it. For a call option on an index, the option is covered if a Fund maintains
with its custodian a diversified portfolio of securities comprising the index or
liquid assets equal to the contract value. A call option is also covered if a
Fund holds a call on the same instrument or index as the call written where the
exercise price of the call held is (i) equal to or less than the exercise price
of the call written, or (ii) greater than the exercise price of the call written
provided the difference is maintained by the Fund in liquid assets in a
segregated account with its custodian. The Funds will write put options only if
they are "secured" by liquid assets maintained in a segregated account by the
Funds' custodian in an amount not less than the exercise price of the option at
all times during the option period.

    A Fund's obligation to sell an instrument subject to a covered call option
written by it, or to purchase an instrument subject to a secured put option
written by it, may be terminated prior to the expiration date of the option by
the Fund's execution of a closing purchase transaction, which is effected by
purchasing on an exchange an option of the same series (i.e., same underlying
instrument, exercise price and expiration date) as the option previously
written. Such a purchase 

                                      19
<PAGE>
 
does not result in the ownership of an option. A closing purchase transaction is
ordinarily effected to realize a profit on an outstanding option, to prevent an
underlying instrument from being called, to permit the sale of the underlying
instrument or to permit the writing of a new option containing different terms
on such underlying instrument. The cost of such a liquidation purchase plus
transaction costs may be greater than the premium received upon the original
option, in which event the Fund will have incurred a loss in the transaction.
There is no assurance that a liquid secondary market will exist for any
particular option. An option writer, unable to effect a closing purchase
transaction, will not be able to sell the underlying instrument (in the case of
a covered call option) or liquidate the segregated account (in the case of a
secured put option) until the option expires or the optioned instrument or
currency is delivered upon exercise with the result that the writer in such
circumstances will be subject to the risk of market decline or appreciation in
the instrument during such period.

    When a Fund purchases an option, the premium paid by it is recorded as an
asset of the Fund. When a Fund writes an option, an amount equal to the net
premium (the premium less the commission) received by a Fund is included in the
liability section of the Fund's statement of assets and liabilities as a
deferred credit. The amount of this asset or deferred credit will be
subsequently marked-to-market to reflect the current value of the option
purchased or written. The current value of the traded option is the last sale
price or, in the absence of a sale, the current bid price. If an option
purchased by a Fund expires unexercised the Fund realizes a loss equal to the
premium paid. If a Fund enters into a closing sale transaction on an option
purchased by it, the Fund realizes a gain if the premium received by the Fund on
the closing transaction is more than the premium paid to purchase the option, or
a loss if it is less. If an option written by a Fund expires on the stipulated
expiration date or if a Fund enters into a closing purchase transaction, it
realizes a gain (or loss if the cost of a closing purchase transaction exceeds
the net premium received when the option is sold) and the deferred credit
related to such option is eliminated. If an option written by a Fund is
exercised, the proceeds of the sale are increased by the net premium originally
received and the Fund  realizes a gain or loss.

    There are several risks associated with transactions in options. For
example, there are significant differences between the securities, currency and
options markets that could result in an imperfect correlation between these
markets, causing a given transaction not to achieve its objectives. In addition,
a liquid secondary market for particular options, whether traded over-the-
counter or on an exchange, may be absent for reasons that include the following:
there may be insufficient trading interest in certain options; restrictions may
be imposed by an exchange on opening transactions or closing transactions or
both; trading halts, suspensions or other restrictions may be imposed with
respect to particular classes or series of options or underlying securities or
currencies; unusual or unforeseen circumstances may interrupt normal operations
on an exchange; the facilities of an exchange or the Options Clearing
Corporation may not be adequate at all times  to handle current trading value;
or one or more exchanges could, for economic or other reasons, decide or be
compelled at some future date to discontinue the trading of options (or a
particular class or series of options), in which event the secondary market on
that exchange (or in that class or series of options) would cease to exist,
although outstanding options that had been issued by the Options Clearing
Corporation as a result of trades on that exchange would continue to be
exercisable in accordance with their terms. A Fund is likely to be unable to
control losses by 

                                      20
<PAGE>
 
closing its position where a liquid secondary market does not exist. A decision
as to whether, when and how to use options involves the exercise of skill and
judgment, and even a well-conceived transaction may be unsuccessful to some
degree because of market behavior or unexpected events.

     The Small Cap Fund may purchase or sell options on individual securities or
options on indices of securities as described below. The purchaser of an option
risks a total loss of the premium paid for the option if the price of the
underlying security does not increase or decrease sufficiently to justify
exercise. The seller of an option, on the other hand, will recognize the premium
as income if the option expires unrecognized but foregoes any capital
appreciation in excess of the exercise price in the case of a call option and
may be required to pay a price in excess of current market value in the case of
a put option.

     Call and Put Options on Specific Securities.  The Small Cap Fund may invest
in call and put options on a specific security.

     A call option gives the purchaser of the option the right to buy, and
obligates the writer to sell, an underlying security at the exercise price at
any time during the option period. Conversely, a put option gives the purchaser
of the option the right to sell, and obligates the writer to buy, an underlying
security at the exercise price at any time during the option period. Investments
by the Fund in off-exchange options will be treated as "illiquid" and therefore
subject to the Fund's policy of not investing more than 15% of its net assets in
illiquid securities.

     The Small Cap Fund may write covered call option contracts and secured put
options as Wells Fargo Bank deems appropriate. A covered call option is a call
option for which the writer of the option owns the security covered by the
option. Covered call options written by the Fund exposes it during the term of
the option (i) to the possible loss of opportunity to realize appreciation in
the market price of the underlying security or (ii) to possible loss caused by
continued holding of a security which might otherwise have been sold to protect
against depreciation in the market price of the security.  If the Fund writes a
secured put option, it assumes the risk of loss should the market value of the
underlying security decline below the exercise price of the option. The
aggregate value of the securities subject to options written by the Fund will
not exceed 15% of the value of the assets of the Small Cap Fund.  The use of
covered call options and securities put options will not be a primary investment
technique of the Fund, and they are expected to be used infrequently. If the
adviser is incorrect in its forecast of market value or other factors when
writing the foregoing options, the Fund would be in a worse position than it
would have been had the foregoing investment techniques not been used.

     The Fund may engage in unlisted over-the-counter options with
broker/dealers deemed creditworthy by the adviser. Closing transactions for such
options are usually effected directly with the same broker/dealer that effected
the original option transaction. The Fund bears the risk that the broker/dealer
will fail to meet its obligations. There is no assurance that a liquid secondary
trading market exists for closing out an unlisted option position. Furthermore,
unlisted options are not subject to the protections afforded purchasers of
listed options by the Options Clearing Corporation, which performs the
obligations of its members who fail to perform in connection with the purchase
or sale of options.

                                      21

    Stock Index Options.  The Small Cap Fund may purchase call and put options
and write covered call options on stock indices listed on national securities
exchanges or traded in the over-the-counter market to the extent of 15% of the
value of its net assets.

    The effectiveness of purchasing or writing stock index options will depend
upon the extent to which price movements in the Fund's investment portfolio
correlate with price movements of the stock index selected. Because the value of
a stock index option depends upon changes to the price of all stocks comprising
the index rather than the price of a particular stock, whether the Fund will
realize a gain or loss from the purchase or writing of options on an index
depends upon movements in the price of all stocks in the index, rather than
movements in the price of a particular stock. Accordingly, successful use by the
Fund of options on stock indexes will be subject to Wells Fargo Bank's ability
to correctly analyze movements in the direction of the stock market generally or
of particular industry or market segments.

    Stock Index Futures Contracts and Options on Stock Index Futures Contracts.
The Equity Value and Balanced Funds may participate in stock index futures
contracts and options on stock index futures contracts. A futures transaction
involves a firm agreement to buy or sell a commodity or financial instrument at
a particular price on a specified future date, while an option transaction
generally involves a right, which may or may not be exercised, to buy or sell a
commodity of financial instrument at a particular price on a specified future
date.  Futures contracts and options are standardized and exchange-traded, where
the exchange serves as the ultimate counterparty for all contracts.
Consequently, the only credit risk on futures contracts is the creditworthiness
of the exchange.  Futures contracts, however, are subject to market risk (i.e.,
exposure to adverse price changes).

    A stock index futures contract is an agreement in which one party agrees to
deliver to the other an amount of cash equal to a specific dollar amount
multiplied by the difference between the value of a specific stock index at the
close of the last trading day of the contract and the price at which the
agreement is made. As the aggregate market value of the stocks in the index
changes, the value of the index also changes. In the event that the index level
rises above the level at which the stock index futures contract was sold, the
seller of the stock index futures contract realizes a loss determined by the
difference between the two index levels at the time of expiration of the stock
index futures contract, and the purchaser realizes a gain in that amount. In the
event the index level falls below the level at which the stock index futures
contract was sold, the seller recognizes a gain determined by the difference
between the two index levels at the expiration of the stock index futures
contract, and the purchaser realizes a loss. Stock index futures contracts
expire on a fixed date, currently one to seven months from the date of the
contract, and are settled upon expiration of the contract.

    Stock index futures contracts may be purchased to protect a Fund against an
increase in the prices of stocks that the Fund intends to purchase. If the Fund
is unable to invest its cash (or cash equivalents) in stock in an orderly
fashion, the Fund may purchase a stock index futures contract to offset any
increase in the price of the stock. However, it is possible that the market may
decline instead, resulting in a loss on the stock index futures contract. If the
Fund then concludes not to invest in stock at that time, or if the price of the
securities to be purchased remains constant or 

                                      22
<PAGE>
 
increases, the Fund realizes a loss on the stock index futures contract that is
not offset by a reduction in the price of securities purchased. The Funds also
may buy or sell stock index futures contracts to close out existing futures
positions.

    The Equity Value and Balanced Funds may also purchase put options on stock
index futures contracts. Sales of such options may also be made to close out an
open option position. The Funds may, for example, purchase a put option on a
particular stock index futures contract or stock index to protect against a
decline in the value of the common stocks it holds. If the stocks in the index
decline in value, the put should become more valuable and the Funds could sell
it to offset losses in the value of the common stocks. In this way, put options
may be used to achieve the same goals the Funds seek in selling futures
contracts. A put option on a stock index future gives the purchaser the right,
in return for a premium paid, to assume a short (i.e., the right to sell stock
index futures) position in a stock index futures contract at a specified
exercise price ("strike price") at any time during the period of the option. If
the option is exercised by the holder before the last trading date during the
option period, the holder receives the futures position, as well as any balance
in the futures margin account. If an option is exercised on the last trading day
prior to the expiration date of the option, the settlement is made entirely in
cash in an amount equal to the difference between the strike price and the
closing level of the relevant index on the expiration date.

    Wells Fargo Bank expects that an increase or decrease in the index in
relation to the strike price level would normally correlate to an increase or
decrease (but not necessarily to the same extent) in the value of a Fund's
common stock portfolio against which the option was written. Thus, any loss in
the option transaction may be offset by an increase in the value of the common
stock portfolio to the extent changes in the index correlate to changes in the
value of that portfolio. The Funds may liquidate the put options they have
purchased by effecting a closing sale transaction rather than exercising the
option. This is accomplished by selling an option of the same series as the
option previously purchased. There is no guarantee that the Funds will be able
to effect the closing sale transaction. The Funds realize a gain from a closing
sale transaction if the price at which the transaction is effected exceeds the
premium paid to purchase the option and, if less, the Funds  realize a loss.

    The Balanced and Equity Value Funds may each invest in stock index futures
in order to protect the value of common stock investments or to maintain
liquidity, provided not more than 5% of a Fund's net assets are committed to
such transactions. A stock index future obligates the seller to deliver (and the
purchaser to take), effectively, an amount of cash equal to a specific dollar
amount times the difference between the value of a specific stock index at the
close of the last trading day of the contract and the price at which the
agreement is made. No physical delivery of the underlying stocks in the index is
made. With respect to stock indices that are permitted investments, the Fund
intends to purchase and sell futures contracts on the stock index for which it
can obtain the best price with consideration also given to liquidity. There can
be no assurance that a liquid market will exist at the time when a Fund seeks to
close out a futures contract or a futures option position. Lack of a liquid
market may prevent liquidation of an unfavorable position.

     Other Investment Companies
     --------------------------

     The Funds may invest in shares of other open-end management investment
companies, up to the limits prescribed in Section 12(d) of the 1940 Act.  Under
the 1940 Act, a Fund's investment in such securities currently is limited to,
subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5% of such Fund's net assets with respect to any one
investment company and (iii) 10% of such Fund's net assets in aggregate.  Other
investment companies in which the Funds invest can be expected to charge fees
for operating expenses such as investment advisory and administration fees, that
would be in addition to those charged by the Funds.

     Privately Issued Securities
     ---------------------------

     The Funds may invest in privately issued securities, including those which
may be resold only in accordance with Rule 144A under the Securities Act of 1933
("Rule 144A Securities"). Rule 144A Securities are restricted securities that
are not publicly traded. Accordingly, the liquidity of the market for specific
Rule 144A Securities may vary. Delay or difficulty in selling such securities
may result in a loss to a Fund. Privately issued or Rule 144A securities that
are determined by the investment adviser to be "illiquid" are subject to the
Funds' policy of not investing more than 15% of its net assets in illiquid
securities.  The investment adviser, under guidelines approved by Board of
Directors of the Company, will evaluate the liquidity characteristics of each
Rule 144A Security proposed for purchase by a Fund on a case-by-case basis and
will consider the following factors, among others, in their evaluation: (1) the
frequency of trades and quotes for the Rule 144A Security; (2) the number of
dealers willing to purchase or sell the Rule 144A Security and the number of
other potential purchasers; (3) dealer undertakings to make a market in the Rule

     U.S. Government Obligations
     ---------------------------

     The Funds may invest in obligations issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government obligations").
Payment of principal and interest on U.S. Government obligations (i) may be
backed by the full faith and credit of the United States (as with U.S. Treasury
bills and GNMA certificates) or (ii) may be backed solely by the issuing or
guaranteeing agency or instrumentality itself (as with FNMA notes). In the
latter case investors must look principally to the agency or instrumentality
issuing or guaranteeing the obligation for ultimate repayment, which agency or
instrumentality may be privately owned. There can be no assurance that the U.S.
Government will provide financial support to its agencies or instrumentalities
where it is not obligated to do so. In addition, U.S. Government obligations are
subject to fluctuations in market value due to fluctuations in market interest
rates. As a general matter, the value of debt instruments, including U.S.
Government obligations, declines when market interest rates increase and rises
when market interest rates decrease.  Certain types of U.S. Government
obligations are subject to fluctuations in yield or value due to their structure
or contract terms.

    Warrants
    --------

    The Balanced, Equity Value and Growth Funds may each invest up to 5% of its
net assets at the time of purchase in warrants (other than those that have been
acquired in units or attached to other securities), and not more than 2% of its
net assets in warrants which are not listed on the New York or American Stock
Exchange.  Warrants represent rights to purchase securities at a specific price
valid for a specific period of time.  The prices of warrants do not necessarily
correlate with the prices of the underlying securities.  A Fund may only
purchase warrants on securities in which the Fund may invest directly.

    Nationally Recognized Statistical Ratings Organizations
    -------------------------------------------------------

    The ratings of Moody's Investors Service, Inc., Standard & Poor's Ratings
Group, Division of McGraw Hill, Duff & Phelps Credit Rating Co., Fitch Investors
Service, Inc. Thomson Bank Watch and IBCA Inc. represent their opinions as to
the quality of debt securities. It should be emphasized, however, that ratings
are general and not absolute standards of quality, and debt securities with the
same maturity, interest rate and rating may have different yields while debt
securities of the same maturity and interest rate with different ratings may
have the same yield. Subsequent to purchase by a Fund, an issue of debt
securities may cease to be rated or its rating may be reduced below the minimum
rating required for purchase by a Fund. The adviser will consider such an event
in determining whether the Fund involved should continue to hold the obligation.

    The payment of principal and interest on debt securities purchased by the
Balanced and Equity Value Funds depends upon the ability of the issuers to meet
their obligations. An issuer's obligations under its debt securities are subject
to the provisions of bankruptcy, insolvency, and other laws affecting the rights
and remedies of creditors, such as the Federal Bankruptcy Code, and laws, if
any, which may be enacted by federal or state legislatures extending the time
for payment of principal or interest, or both, or imposing other constraints
upon enforcement of such obligations or, in the case of governmental entities,
upon the ability of such entities to levy taxes. The power or ability of an
issuer to meet its obligations for the payment of interest and principal of its
debt securities may be materially adversely affected by litigation or other
conditions. Further, it should also be, noted with respect to all municipal
obligations issued after August 15, 1986 (August 31, 1986 in the case of certain
bonds), the issuer must comply with certain rules formerly applicable only to
"industrial development bonds" which, if the issuer fails to observe them, could
cause interest on the municipal obligations to become taxable retroactive to the
date of issue.

                                  RISK FACTORS

    Investments in a Fund are not bank deposits or obligations of Wells Fargo
Bank, are not insured by the FDIC and are not insured against loss of principal.
When the value of the securities that a Fund owns declines, so does the value of
your Fund shares.  You should be prepared to accept some risk with the money you
invest in a Fund.

                                      25
<PAGE>
 
    The portfolio equity securities of each Fund are subject to equity market
risk.  Equity market risk is the risk that stock prices will fluctuate or
decline over short or even extended periods.  Throughout most of 1997, the stock
market, as measured by the S&P 500 Index and other commonly used indices, has
been trading at or close to record levels.  There can be no guarantee that these
performance levels will continue. The portfolio debt instruments of a Fund are
subject to credit and interest-rate risk.  Credit risk is the risk that issuers
of the debt instruments in which a Fund invests may default on the payment of
principal and/or interest.  Interest-rate risk is the risk that increases in
market interest rates may adversely affect the value of the debt instruments in
which the Funds invest and hence the value of your investment in a Fund.

    The market value of a Fund's investment in fixed-income securities will
change in response to various factors, such as changes in market interest-rates
and the relative financial strength of an issuer. During periods of falling
interest rates, the value of fixed-income securities generally rises.
Conversely, during periods of rising interest rates, the value of such
securities generally declines. Debt securities with longer maturities, which
tend to produce higher yields, are subject to potentially greater capital
appreciation and depreciation than obligations with shorter maturities.
Fluctuations in the market value of fixed-income securities can be reduced, but
not eliminated, by variable and floating-rate features.

    Securities rated in the fourth highest rating category are regarded by S&P
as having an adequate capacity to pay interest and repay principal, but changes
in economic conditions or other circumstances are more likely to lead to a
weakened capacity to make such repayments. Moody's considers such securities as
having speculative characteristics. Subsequent to its purchase by the Fund, an
issue of securities may cease to be rated or its rating may be reduced below the
minimum rating required for purchase by the Fund. The adviser will consider such
an event in determining whether a Fund should continue to hold the obligation.
Securities rated below the fourth highest rating category (sometimes called
"junk bonds") are often considered to be speculative and involve greater risk of
default or price changes due to changes in the issuer's credit-worthiness. The
market prices of these securities may fluctuate more than higher quality
securities and may decline significantly in periods of general economic
difficulty.

    There may be some additional risks associated with investments in smaller
and/or newer companies because their shares tend to be less liquid than
securities of larger companies. Further, shares of small and new companies are
generally more sensitive to purchase and sale transactions and changes in the
issuer's financial condition and, therefore, the prices of such stocks may be
more volatile than those of larger company stocks and may be subject to more
abrupt price movements than securities of larger companies.

    Investing in the securities of issuers in any foreign country, including
American Depository Receipts ("ADRs") and European Depository Receipts ("EDRs")
and similar securities, involves special risks and considerations not typically
associated with investing in U.S. companies. These include differences in
accounting, auditing and financial reporting standards; generally higher
commission rates on foreign portfolio transactions; the possibility of
nationalization, expropriation or confiscatory taxation; adverse changes in
investment or exchange control regulations (which 

                                      26
<PAGE>
 
may include suspension of the ability to transfer currency from a country); and
political, social and monetary or diplomatic developments that could affect U.S.
investments in foreign countries. Additionally, dispositions of foreign
securities and dividends and interest payable on those securities may be subject
to foreign taxes, including withholding taxes. Foreign securities often trade
with less frequency and volume than domestic securities and, therefore, may
exhibit greater price volatility. Additional costs associated with an investment
in foreign securities may include higher custodial fees than apply to domestic
custodial arrangements and transaction costs of foreign currency conversions.
Changes in foreign exchange rates also will affect the value of securities
denominated or quoted in currencies other than the U.S. dollar. A Fund's
performance may be affected either unfavorably or favorably by fluctuations in
the relative rates of exchange between the currencies of different nations, by
exchange control regulations and by indigenous economic and political
developments.

    There are special risks involved in investing in emerging-market countries.
Many investments in emerging markets can be considered speculative, and their
prices can be much more volatile than in the more developed nations of the
world. This difference reflects the greater uncertainties of investing in less
established markets and economies. In addition, the financial markets of
emerging markets countries are generally less well capitalized and thus
securities of issuers based in such countries may be less liquid.  Further, such
markets may be vulnerable to high inflation and interest rates.  Most are
heavily dependent on international trade, and some are especially vulnerable to
recessions in other countries. Some of these countries are also sensitive to
world commodity prices and may be subject to political and social uncertainties.

    Illiquid securities, which may include certain restricted securities, may be
difficult to sell promptly at an acceptable price. Certain restricted securities
may be subject to legal restrictions on resale. Delay or difficulty in selling
securities may result in a loss or be costly to a Fund.

    The adviser may use certain derivative investments or techniques, such as
buying and selling options and futures contracts and entering into currency
exchange contracts or swap agreements, to adjust the risk and return
characteristics of a Fund's portfolio. Derivatives are financial instruments
whose value is derived, at least in part, from the price of another security or
a specified asset, index or rate. Some derivatives may be more sensitive than
direct securities to changes in interest rates or sudden market moves. Some
derivatives also may be susceptible to fluctuations in yield or value due to
their structure or contract terms. If a Fund's adviser judges market conditions
incorrectly, the use of certain derivatives could result in a loss, regardless
of the adviser's intent in using the derivatives.

    The Funds pursue an active trading investment strategy, and the length of
time a Fund has held a particular security is not generally a consideration in
investment decisions. Accordingly, the portfolio turnover rate for the Funds may
be higher than that of other funds that do not pursue an active trading
investment strategy. Portfolio turnover generally involves some expense to a
Fund, including brokerage commissions or dealer mark-ups and other transaction
costs on the sale of securities and the reinvestment in other securities.
Portfolio turnover also can generate short-term capital gains tax consequences.

                                      27
<PAGE>
 
    There is, of course, no assurance that a Fund will achieve its investment
objective or be successful in preventing or minimizing the risk of loss that is
inherent in investing in particular types of investment products.

     As of January 1, 1998, Peter G. Gordon will replace Robert M. Joses on the
Board of Directors of the Wells Fargo Fund Complex.

     Directors of the Company are compensated annually by the Company and by all
the registrants in each fund complex they serve as indicated above and also are
reimbursed for all out-of-pocket expenses relating to attendance at board
meetings.  The Company, Stagecoach Trust and 

                                      29
<PAGE>
 
Life & Annuity Trust are considered to be members of the same fund complex as
such term is defined in Form N-1A under the 1940 Act (the "Wells Fargo Fund
Complex"). Overland Express Funds, Inc. and Master Investment Trust, two
investment companies previously advised by Wells Fargo Bank, were part of the
Wells Fargo Fund Complex prior to December 12, 1997. These companies are no
longer part of the Wells Fargo Fund Complex. MasterWorks Funds Inc., Master
Investment Portfolio, and Managed Series Investment Trust together form a
separate fund complex (the "BGFA Fund Complex"). Each of the Directors and
Officers of the Company serves in the identical capacity as directors and
officers or as trustees and/or officers of each registered open-end management
investment company in both the Wells Fargo and BGFA Fund Complexes, except for
Joseph N. Hankin, who only serves the aforementioned members of the Wells Fargo
Fund Complex. The Directors are compensated by other companies and trusts within
a fund complex for their services as directors/trustees to such companies and
trusts. Currently the Directors do not receive any retirement benefits or
deferred compensation from the Company or any other member of each fund complex.

     As of the date of this SAI, Directors and officers of the Company, as a
group, beneficially owned less than 1% of the outstanding shares of the Company.

     INVESTMENT ADVISER.  Wells Fargo Bank provides investment advisory services

to the Funds.  As investment adviser, Wells Fargo Bank furnishes investment
guidance and policy direction in connection with the daily portfolio management
of the Funds.  Wells Fargo Bank furnishes to the Board of Directors periodic
reports on the investment strategy and performance of each Fund.  Wells Fargo
Bank provides the Funds with, among other things, money market security and
fixed-income research, analysis and statistical and economic data and
information concerning interest rate and securities markets trends, portfolio
composition, and credit conditions.

     As compensation for its advisory services, Wells Fargo Bank is entitled to
receive a monthly fee at the annual rates indicated below of each Fund's average
daily net assets:

the predecessor portfolio to the Balanced and Equity Value Funds was San Diego
Financial Capital Management, Inc. ("San Diego Financial"), which was a wholly
owned subsidiary of San Diego Trust & Savings Bank ("San Diego Trust"), which in
turn was a wholly owned subsidiary of San Diego Financial Corporation ("SDFC").
On that date, SDFC merged into First Interstate Bancorp and San Diego Trust
merged into First Interstate Bank of California ("FICAL"). As a result of these
transactions, San Diego Financial became an indirect wholly-owned subsidiary of
FICAL. On January 12, 1995, San Diego Financial merged into First Interstate
Investment Services, Inc., a direct wholly-owned subsidiary of FICAL, which has
since changed its name to First Interstate Capital Management, Inc.

     The Pacifica Balanced and Equity Value Funds were reorganized as the
Company's Balanced and Equity Value Funds on September 6, 1996. Prior to
September 6, 1996, Wells Fargo Investment Management, Inc. ("WFIM") and its
predecessor, First Interstate Capital Management, Inc. ("FICM") served as
adviser to the Pacifica Balanced and Equity Value Funds. As of September 6,
1996, Wells Fargo Bank became the adviser to the Company's Balanced and Equity
Value Funds.

     For the period begun April 1, 1996 and ended September 5, 1996, the
predecessor portfolios paid to WFIM, and for the period begun September 6, 1996

services to the Collective Investment Fund, the predecessor to the Small Cap
Fund. For these services Wells Fargo charged fees at an annual rate of 0.75% of
the Collective Investment Fund's average net assets. Wells Fargo was also
entitled to be reimbursed by the Collective Investment Fund for expenses
incurred on its behalf, excluding costs incurred in establishing and organizing
the Fund. The Collective Investment Fund was entitled to pay up to 0.10% of its
net assets for "Audit Expenses." There were no sales charges. The Collective
Investment Fund paid all brokerage commissions incurred on its portfolio
transactions.

     The Small Cap Fund previously did not engage an investment adviser because
it invested all of its assets in a Master Portfolio (which had the same
investment objective as the Fund) that was advised by Wells Fargo Bank. The
Small Cap Fund invested in the Small Cap Master Portfolio. The terms of the
Master Portfolio's advisory contract were identical in all material respects to
the terms of the Fund's existing advisory contract. For the period begun
September 16, 1996 (the Small Cap Fund's commencement of operations) and ended
September 30, 1996, the Small Cap Master Portfolio paid to Wells Fargo Bank
$6,129 in advisory fees on behalf of the Small Cap Fund. No fees were waived.

such continuance is approved by a majority vote of the Directors of the Company,
including a majority of the Directors who are not "interested persons" (as
defined in the 1940 Act) of the Funds ("Non-Interested Directors").  Any form of
Servicing Agreement related to a Servicing Plan also must be approved by such
vote of the Directors and Non-Interested Directors.  Servicing Agreements may be
terminated at any time, without payment of any penalty, by vote of a majority of
the Board of Directors, including a majority of the Non-Interested Directors.
No material amendment to the Servicing Plans or related Servicing Agreements may
be made except by a majority of both the Directors of the Company and the Non-
Interested Directors.
 
     Each Servicing Plan requires that the Administrator shall provide to the
Directors, and the Directors shall review, at least quarterly, a written report
of the amounts expended (and purposes therefor) under the Servicing Plan.

                           PERFORMANCE CALCULATIONS

     The Funds may advertise certain yield and total return information.
Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown.  Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.

     In connection with communicating its performance to current or prospective
shareholders, these figures may also be compared to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

     Performance information for a Fund or Class of shares in a Fund may be
useful in reviewing the performance of such Fund or Class of shares and for
providing a basis for comparison with investment alternatives.  The yield of a
Fund and the yield of a Class of shares in a Fund, however, may not be
comparable to the yields from investment alternatives because of differences in
the foregoing variables and differences in the methods used to value portfolio
securities, compute expenses and calculate yield.

     TOTAL RETURN:  The Funds may advertise certain total return information
     ------------                                                           
computed in the manner described in the Prospectus. As and to the extent
required by the SEC, an average annual compound rate of return ("T") is computed
by using the redeemable value at the end of a specified period ("ERV") of a
hypothetical initial investment ("P") over a period of years ("n") according to
the following formula: P(1+T)n=ERV. In addition, as indicated in each
Prospectus, each Fund also may, at times, calculate total return based on net
asset value per share (rather than the public offering price), in which case the
figures would not reflect the effect of any sales charges that would have been
paid by an investor, or based on the assumption that a sales charge other than
the maximum sales charge (reflecting a Volume Discount) was assessed, provided
that total return data derived pursuant to the calculation described above also
are presented.

     Performance information may be advertised for non-standardized periods,
including year-to-date and other periods less than a year for the Funds.

     YIELD CALCULATIONS:  The Funds may, from time to time, include their yields
     ------------------                                                         
and effective yields in advertisements or reports to shareholders or prospective
investors.  Quotations of yield for the Funds are based on the investment income
per share earned during a particular seven-day or thirty-day period, less
expenses accrued during a period ("net investment income") and are computed by
dividing net investment income by the offering price per share on the last date
of the period, according to the following formula:

                          YIELD - 2[(a - b + 1)/6/ -1]
                                     -----            

                                       Cd
                                        
     where a = dividends and interest earned during the period, b = expenses
accrued for the period (net of any reimbursements), c = the average daily number
of shares outstanding during the period that were entitled to receive dividends,
and d = the maximum offering price per share on the last day of the period.

     EFFECTIVE YIELD:  Effective yields for the Funds are based on the change in
     ---------------                                                            
the value of a hypothetical investment (exclusive of capital changes) over a
particular thirty-day period, less a pro-rata share of each Fund's expenses
accrued over that period (the "base period"), and stated as a percentage of the
investment at the start of the base period (the "base period return").  The base
period return is then annualized multiplying by 365/30, with the resulting yield
figure carried to at least the nearest hundredth of one percent.  "Effective
yield" for the Funds assumes that all dividends received during the period have
been reinvested.  Calculation of "effective yield" begins with the same "base
period return" used in the calculation of yield, which is then annualized to
reflect weekly compounding pursuant to the following formula:

        Effective Thirty-Day Yield = [(Base Period Return +1)365/30]-1.

     From time to time and only to the extent the comparison is appropriate for
a Fund or a Class of shares, the Company may quote the performance or price-
earning ratio of a Fund or Class in advertising and other types of literature as
compared to the performance of the S&P Index, the Dow Jones Industrial Average,
the Lehman Brothers 20+ Treasury Index, the Lehman Brothers 5-7 Year Treasury
Index, Donoghue's Money Fund Averages, Real Estate Investment Averages (as
reported by the National Association of Real Estate Investment Trusts), Gold
Investment Averages (provided by World Gold Council), Bank Averages (which are
calculated from figures supplied by the U.S. League of Savings Institutions
based on effective annual rates of interest on both passbook and certificate
accounts), average annualized certificate of deposit rates (from the Federal
Reserve G-13 Statistical Releases or the Bank Rate Monitor), the Salomon One
Year Treasury Benchmark Index, the Consumer Price Index (as published by the
U.S. Bureau of Labor Statistics), other managed or unmanaged indices or
performance data of bonds, municipal securities, stocks or government securities
(including data provided by Ibbotson Associates), or by other services,
companies, publications or persons who monitor mutual funds on overall
performance or other criteria. The S&P Index and the Dow Jones Industrial
Average are unmanaged indices of selected common stock prices. The performance
of the Funds or a Class also may be compared to that of other mutual funds
having similar objectives. This comparative performance could be expressed as a
ranking prepared by Lipper Analytical Services, Inc., CDA Investment
Technologies, Inc., Bloomberg Financial Markets or Morningstar, Inc.,
independent services which monitor the performance of mutual funds. The Funds'
performance will be calculated by relating net asset value per share at the
beginning of a stated period to the net asset value of the investment, assuming
reinvestment of all gains distributions and dividends paid, at the end of the
period. The Funds' comparative performance will be based on a comparison of
yields, as described above, or total return, as reported by Lipper, Survey
Publications, Donoghue or Morningstar, Inc.

     Any such comparisons may be useful to investors who wish to compare past
performance of the Funds or a Class with that of competitors.  Of course, past
performance cannot be a guarantee of future results.  The Company also may
include, from time to time, a reference to certain marketing approaches of the
Distributor, including, for example, a reference to a potential shareholder
being contacted by a selected broker or dealer.  General mutual fund statistics
provided by the Investment Company Institute may also be used.

                                      42
<PAGE>
 
     The Company also may use the following information in advertisements and
other types of literature, only to the extent the information is appropriate for
the Fund:  (i) the Consumer Price Index may be used to assess the real rate of
return from an investment in a Fund; (ii) other government statistics,
including, but not limited to, The Survey of Current Business, may be used to
illustrate investment attributes of a Fund or the general economic, business,
investment, or financial environment in which a Fund operates; (iii) the effect
of tax-deferred compounding on the investment returns of a Fund, or on returns
in general, may be illustrated by graphs, charts, etc., where such graphs or
charts would compare, at various points in time, the return from an investment
in a Fund (or returns in general) on a tax-deferred basis (assuming reinvestment
of capital gains and dividends and assuming one or more tax rates) with the
return on a taxable basis; and (iv) the sectors or industries in which a Fund
invests may be compared to relevant indices of stocks or surveys (e.g., S&P
Industry Surveys) to evaluate a Fund's historical performance or current or
potential value with respect to the particular industry or sector.

     In addition, the Company also may use, in advertisements and other types of
literature, information and statements: (1) showing that bank savings accounts
offer a guaranteed return of principal and a fixed rate of interest, but no
opportunity for capital growth; and (2)  describing Wells Fargo Bank, and its
affiliates and predecessors, as one of the first investment managers to advise
investment accounts using asset allocation and index strategies.  The Company
also may include in advertising and other types of literature information and
other data from reports and studies prepared by the Tax Foundation, including
information regarding federal and state tax levels and the related "Tax Freedom
Day."

     The Company also may discuss in advertising and other types of literature
that a Fund has been assigned a rating by a nationally recognized statistical
rating organization ("NRSRO"), such as Standard & Poor's Corporation.  Such
rating would assess the creditworthiness of the investments held by the Fund.
The assigned rating would not be a recommendation to purchase, sell or hold the
Fund's shares since the rating would not comment on the market price of the
Fund's shares or the suitability of the Fund for a particular investor.  In
addition, the assigned rating would be subject to change, suspension or
withdrawal as a result of changes in, or unavailability of, information relating
to the Fund or its investments.  The Company may compare the Fund's performance
with other investments which are assigned ratings by NRSROs.  Any such

                       DETERMINATION OF NET ASSET VALUE


     Net asset value per share for each class of the Funds is determined as of
the close of regular trading (currently 1:00 p.m., Pacific time) on each day the
NYSE is open for business.  Expenses and fees, including advisory fees, are
accrued daily and are taken into account for the purpose of determining the net
asset value of the Funds' shares.

     Securities of a Fund for which market quotations are available are valued
at latest prices.  Any security for which the primary market is an exchange is
valued at the last sale price on such exchange on the day of valuation or, if
there was no sale on such day, the latest bid price quoted on such day.  In the
case of other securities, including U.S. Government securities but excluding
money market instruments maturing in 60 days or less, the valuations are based
on latest quoted bid prices.  Money market instruments and debt securities
maturing in 60 days or less are valued at amortized cost.  The assets of a Fund,
other than money market instruments or debt securities maturing in 60 days or
less, are valued at latest quoted bid prices.  Futures contracts will be marked
to market daily at their respective settlement prices determined by the relevant
exchange.  Prices may be furnished by a reputable independent pricing service
approved by the Company's Board of Directors.  Prices provided by an independent
pricing service may be determined without exclusive reliance on quoted prices
and may take into account appropriate factors such as institutional-size trading
in similar groups of securities, yield, quality, coupon rate, maturity, type of
issue, trading characteristics and other market data.  All other securities and
other assets of a Fund for which current market quotations are not readily
available are valued at fair value as determined in good faith by the Company's
Board of Directors and in accordance with procedures adopted by the  Directors.


                ADDITIONAL PURCHASE AND REDEMPTION INFORMATION
                                        
     Shares may be purchased on any day a Fund is open for business.  Each Fund
is open for business each day the New York Stock Exchange ("NYSE") is open for
trading (a "Business Day"). Currently, the NYSE is closed on New Year's Day,
Martin Luther King Jr. Day, Presidents' Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day (each a
"Holiday"). When any Holiday falls on a weekend, the NYSE typically is closed on
the weekday immediately before or after such Holiday.

     Payment for shares may, in the discretion of the adviser, be made in the
form of securities that are permissible investments for the Fund.  For further
information about this form of payment please contact Stephens.  In connection
with an in-kind securities payment, the Funds will require, among other things,
that the securities be valued on the day of purchase in accordance with the
pricing methods used by a Fund and that a Fund receives satisfactory assurances
that (i) it will have good and marketable title to the securities received by
it; (ii) that 

                                      45
<PAGE>
 
the securities are in proper form for transfer to the Fund; and (iii) adequate
information will be provided concerning the basis and other matters relating to
the securities.

     Under the 1940 Act, the Fund may suspend the right of redemption or
postpone the date of payment upon redemption for any period during which the
NYSE is closed (other than customary weekend and holiday closings, or during
which trading is restricted, or during which as determined by the SEC by rule or
regulation) an emergency exists as a result of which disposal or valuation of
portfolio securities is not reasonably practicable, or for such periods as the
SEC may permit.  The Company may suspend redemption rights or postpone
redemption payments for such periods as are permitted under the 1940 Act.  The
Company may also redeem shares involuntarily or make payment for redemption in
securities or other property if it appears appropriate to do so in light of the
Company's responsibilities under the 1940 Act.  In addition, the Company may
redeem shares involuntarily to reimburse the Fund for any losses sustained by
reason of the failure of a shareholders to make full payment for shares
purchased or to collect any charge relating to a transaction effected for the
benefit of a shareholder which is applicable to shares of the Fund as provided
from time to time in the Prospectus.


                            PORTFOLIO TRANSACTIONS

     The Company has no obligation to deal with any dealer or group of dealers
in the execution of transactions in portfolio securities.  Subject to policies
established by the Company's Board of Directors, Wells Fargo Bank is responsible
for each Fund's portfolio decisions and the placing of portfolio transactions.
In placing orders, it is the policy of the Company to obtain the best results
taking into account the dealer's general execution and operational facilities,
the type of transaction involved and other factors such as the dealer's risk in
positioning the securities involved.  While Wells Fargo Bank generally seeks
reasonably competitive spreads or commissions, the Funds will not necessarily be
paying the lowest spread or commission available.

     Purchases and sales of equity securities on a securities exchange are
effected through brokers who charge a negotiated commission for their services.
Orders may be directed to any broker including, to the extent and in the manner
permitted by applicable law, Stephens or Wells Fargo Securities Inc.  In the
over-the-counter market, securities are generally traded on a "net" basis with
dealers acting as principal for their own accounts without a stated commission,
although the price of the security usually includes a profit to the dealer.  In
underwritten offerings, securities are purchased at a fixed price that includes
an amount of compensation to the underwriter, generally referred to as the
underwriter's concession or discount.  The Asset Allocation Fund will not deal
with Stephens, Wells Fargo Bank or their affiliates in any transaction in which
any of them acts as principal without an exemptive order from the Commission.

     In placing orders for portfolio securities of the Fund, Wells Fargo Bank is
required to give primary consideration to obtaining the most favorable price and
efficient execution.  This means that Wells Fargo Bank will seek to execute each
transaction at a price and commission, if 

                                      46
<PAGE>
 
any, that provide the most favorable total cost or proceeds reasonably
attainable in the circumstances. While Wells Fargo Bank will generally seek
reasonably competitive spreads or commissions, the Asset Allocation Fund will
not necessarily be paying the lowest spread or commission available. Commission
rates are established pursuant to negotiations with the broker based on the
quality and quantity of execution services provided by the broker in the light
of generally prevailing rates. The allocation of orders among brokers and the
commission rates paid are reviewed periodically by the Board of Directors.

     Wells Fargo Bank, as the Investment Adviser of each of the Funds, may, in
circumstances in which two or more dealers are in a position to offer comparable
results for a Fund portfolio transaction, give preference to a dealer that has
provided statistical or other research services to Wells Fargo Bank.  By
allocating transactions in this manner, Wells Fargo Bank is able to supplement
its research and analysis with the views and information of securities firms.
Information so received will be in addition to, and not in lieu of, the services
required to be performed by Wells Fargo Bank under the Advisory Contracts, and
the expenses of Wells Fargo Bank will not necessarily be reduced as a result of
the receipt of this supplemental research information.  Furthermore, research
services furnished by dealers through which Wells Fargo Bank places securities
transactions for a Fund may be used by Wells Fargo Bank in servicing its other
accounts, and not all of these services may be used by Wells Fargo Bank in
connection with advising the Funds.

     Balanced and Equity Value Funds.  Purchases and sales of non-equity
     -------------------------------                                    
securities usually will be principal transactions.  Portfolio securities
normally will be purchased or sold from or to dealers serving as market makers
for the securities at a net price.  Each of the Funds also will purchase
portfolio securities in underwritten offerings and may purchase securities
directly from the issuer.  Generally, municipal obligations and taxable money
market securities are traded on a net basis and do not involve brokerage
commissions.  The cost of executing a Fund's portfolio securities transactions
will consist primarily of dealer spreads and underwriting commissions.  Under
the Act, persons affiliated with the Company are prohibited from dealing with
the Company as a principal in the purchase and sale of securities unless an
exemptive order allowing such transactions is obtained from the Commission or an
exemption is otherwise available.  The Fund may purchase securities from
underwriting syndicates of which Stephens or Wells Fargo Bank is a member under
certain conditions in accordance with the provisions of a rule adopted under the
Act and in compliance with procedures adopted by the Board of Directors.

     Brokerage Commissions.  For the six-month period ended March 31, 1997, the

     ----------------------------------------

    Portfolio Turnover.  The portfolio turnover rate is not a limiting factor
    ------------------                                                       
when Wells Fargo Bank deems portfolio changes appropriate.  Changes may be made
in the portfolios consistent with the investment objectives and policies of the
Funds whenever such changes are believed to be in the best interests of the
Funds and their shareholders. The portfolio turnover rate is calculated by

                                      48
<PAGE>
 
dividing the lesser of purchases or sales of portfolio securities by the average
monthly value of the Fund's portfolio securities. For purposes of this
calculation, portfolio securities exclude all securities having a maturity when
purchased of one year or less.  Portfolio turnover generally involves some
expenses to the Funds, including brokerage commissions or dealer mark-ups and
other transaction costs on the sale of securities and the reinvestment in other
securities.  Portfolio turnover also can generate short-term capital gain tax
consequences.  Portfolio turnover rate is not a limiting factor when Wells Fargo
Bank deems portfolio changes appropriate.


                                 FUND EXPENSES

     From time to time, except for the expenses borne by Wells Fargo Bank and
Stephens, the Company bears all costs of its operations, including the
compensation of its Directors who are not affiliated with Stephens or Wells
Fargo Bank or any of their affiliates; advisory, shareholder servicing and
administration fees; payments pursuant to any Plan; interest charges; taxes;
fees and expenses of its independent accountants, legal counsel, transfer agent
and dividend disbursing agent; expenses of redeeming shares; expenses of
preparing and printing prospectuses (except the expense of printing and mailing
prospectuses used for promotional purposes, unless otherwise payable pursuant to
a Plan), shareholders' reports, notices, proxy statements and reports to
regulatory agencies; insurance premiums and certain expenses relating to
insurance coverage; trade association membership dues; brokerage and other
expenses connected with the execution of portfolio transactions; fees and
expenses of its custodian, including those for keeping books and accounts and
calculating the NAV per share of the Fund; expenses of shareholders' meetings;
expenses relating to the issuance, registration and qualification of the Fund's
shares; pricing services, and any extraordinary expenses.  Expenses attributable
to the Fund are charged against  Fund assets.  General expenses of the Company
are allocated among all of the funds of the Company, including the Funds, in a
manner proportionate to the net assets of a Funds, on a transactional basis, or
on such other basis as the Company's Board of Directors deems equitable.

                             FEDERAL INCOME TAXES

     The following information supplements and should be read in conjunction
with the Prospectus section entitled "Taxes."  The Prospectus describes
generally the tax treatment of distributions by the Funds.  This section of the
SAI includes additional information concerning income taxes.

     General.  The Company intends to qualify each Fund as a regulated
     -------                                                          
investment company under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code"), as long as such qualification is in the best interest of
the Fund's shareholders.  Each Fund will be treated as a separate entity for tax
purposes and thus the provisions of the Code applicable to regulated investment
companies will generally be applied to each Fund, rather than to the Company as
a whole.  In addition, net capital gain, net investment income, and operating
expenses will be determined separately for each Fund. As a regulated investment
company, each Fund will not be taxed on its net investment income and capital
gains distributed to its shareholders.

                                      49
<PAGE>
 
     Qualification as a regulated investment company under the Code requires,
among other things, that (a) each Fund derive at least 90% of its annual gross
income from dividends, interest, certain payments with respect to securities
loans, gains from the sale or other disposition of stock or securities or
foreign currencies (to the extent such currency gains are directly related to
the regulated investment company's principal business of investing in stock or
securities) and other income (including but not limited to gains from options,
futures or forward contracts) derived with respect to its business of investing
in such stock, securities or currencies; and (b) the Fund diversify its holdings
so that, at the end of each quarter of the taxable year, (i) at least 50% of the
market value of the Fund's assets is represented by cash, government securities
and other securities limited in respect of any one issuer to an amount not
greater than 5% of the Fund's 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
obligations and the securities of other regulated investment companies), or in
two or more issuers which the Fund controls and which are determined to be
engaged in the same or similar trades or businesses.

     The Funds must also distribute or be deemed to distribute to their
shareholders at least 90% of their net investment income earned in each taxable
year.  In general, these distributions must actually or be deemed to be made in
the taxable year.  However, in certain circumstances, such distributions may be
made in the 12 months following the taxable year.  The Funds intend to pay out
substantially all of their net investment income and net realized capital gains
(if any) for each year.

     In addition, a regulated investment company must, in general, derive less
than 30% of its gross income from the sale or other disposition of securities or
options thereon held for less than three months.  However, this restriction has
been repealed with respect to a regulated investment company's taxable years
beginning after August 5, 1997.

 

     Excise Tax.  A 4% nondeductible excise tax will be imposed on each Fund
     ----------                                                             
(other than to the extent of its tax-exempt interest income) to the extent it
does not meet certain minimum distribution requirements by the end of each
calendar year.  Each Fund intends to actually or be deemed to distribute
substantially all of its net investment income and net capital gains by the end
of each calendar year and, thus, expects not to be subject to the excise tax.

     Taxation of Fund Investments.  Except as provided herein, gains and losses
     ----------------------------                                              
on the sale of portfolio securities by a Fund will generally be capital gains
and losses.  Such gains and losses will ordinarily be long-term capital gains
and losses if the securities have been held by the Fund for more than one year
at the time of disposition of the securities.

    Gains recognized on the disposition of a debt obligation (including tax-
exempt obligations purchased after April 30, 1993) purchased by the Fund at a
market discount (generally at a price less than its principal amount) will be
treated as ordinary income to the extent of the portion of market discount which
accrued, but was not previously recognized pursuant to an available election,
during the term the Fund held the debt obligation.

                                      50
<PAGE>
 
     If an option granted by a Fund lapses or is terminated through a closing
transaction, such as a repurchase by the Fund of the option from its holder, the
Fund will realize a short-term capital gain or loss, depending on whether the
premium income is greater or less than the amount paid by the Fund in the
closing transaction.  Some realized capital losses may be deferred if they
result from a position which is part of a "straddle," discussed below.  If
securities are sold by a Fund pursuant to the exercise of a call option written
by it, the Fund will add the premium received to the sale price of the
securities delivered in determining the amount of gain or loss on the sale.

     Under Section 1256 of the Code, a Fund will be required to "mark to market"
its positions in "Section 1256 contracts," which generally include regulated
futures contracts and listed options.  In this regard, Section 1256 contracts
will be deemed to have been sold at market value.  Sixty percent (60%) of any
net gain or loss realized on all dispositions of Section 1256 contracts,
including deemed dispositions under the mark-to-market regime, will generally be
treated as long-term capital gain or loss, and the remaining forty percent (40%)
will be treated as short-term capital gain or loss.  Transactions that qualify
as designated hedges are excepted from the mark-to-market and 60%/40% rules.

     Under Section 988 of the Code, a Fund will generally recognize ordinary
income or loss to the extent gain or loss realized on the disposition of
portfolio securities is attributable to changes in foreign currency exchange
rates.  In addition, gain or loss realized on the disposition of a foreign
currency forward contract, futures contract, option or similar financial
instrument, or of foreign currency itself, will generally be treated as ordinary
income or loss.  The Funds will attempt to monitor Section 988 transactions,
where applicable, to avoid adverse tax impact.

     Offsetting positions held by a regulated investment company involving
certain financial forward, futures or options contracts may be considered, for
tax purposes, to constitute "straddles."  "Straddles" are defined to include
"offsetting positions" in actively traded personal property.  The tax treatment
of "straddles" is governed by Section 1092 of the Code which, in certain
circumstances, overrides or modifies the provisions of Section 1256.  If a
regulated investment company were treated as entering into "straddles" by
engaging in certain financial forward, futures or option contracts, such
straddles could be characterized as "mixed straddles" if the futures, forwards,
or options comprising a part of such straddles were governed by Section 1256 of
the Code.  The regulated investment company may make one or more elections with
respect to "mixed straddles."  Depending upon which election is made, if any,
the results with respect to the regulated investment company may differ.
Generally, to the extent the straddle rules apply to positions established by
the regulated investment company, losses realized by the regulated investment
company may be deferred to the extent of unrealized gain in any offsetting
positions.  Moreover, as a result of the straddle and the conversion transaction
rules, short-term capital loss on straddle positions may be recharacterized as
long-term capital loss, and long-term capital gain may be characterized as
short-term capital gain or ordinary income.

     If a Fund enters into a "constructive sale" of any appreciated position in
stock, a partnership interest, or certain debt instruments, the Fund must
recognize gain (but not loss) with respect to that position.  For this purpose,
a constructive sale occurs when the Fund enters into 

                                      51
<PAGE>
 
one of the following transactions with respect to the same or substantially
identical property: (i) a short sale; (ii) an offsetting notional principal
contract; or (iii) a futures or forward contract.

     If a Fund purchases shares in a "passive foreign investment company"
("PFIC"), the Fund may be subject to federal income tax and an interest charge
imposed by the IRS upon certain distributions from the PFIC or the Fund's
disposition of its PFIC shares.  If the Fund invests in a PFIC, the Fund intends
to make an available election to mark-to-market its interest in PFIC shares.
Under the election, the Fund will be treated as recognizing at the end of each
taxable year the difference, if any, between the fair market value of its
interest in the PFIC shares and its basis in such shares.  In some
circumstances, the recognition of loss may be suspended.  The Fund will adjust
its basis in the PFIC shares by the amount of income (or loss) recognized.
Although such income (or loss) will be taxable to the Fund as ordinary income
(or loss) notwithstanding any distributions by the PFIC, the Fund will not be
subject to federal income tax or the interest charge with respect to its
interest in the PFIC.

     Foreign Taxes.  Income and dividends received by a Fund from sources within
     -------------                                                              
foreign countries may be subject to withholding and other taxes imposed by such
countries.  Tax conventions between certain countries and the United States may
reduce or eliminate such taxes.  Although in some circumstances a regulated
investment company can elect to "pass through" foreign tax credits to its
shareholders, the Funds do not expect to be eligible to make such an election.

     Capital Gain Distributions.  Distributions which are designated by a Fund
     --------------------------                                               
as capital gain distributions will be taxed to shareholders as long-term capital
gain (to the extent such dividends do exceed the Fund's actual net capital gain
for the taxable year), regardless of how long a shareholder has held Fund
shares.  Such distributions will be designated as capital gain distributions in
a written notice mailed by the Fund to its shareholders not later than 60 days
after the close of the Fund's taxable year.

     The Taxpayer Relief Act of 1997 (the "1997 Act") created several new
categories of capital gains applicable to noncorporate taxpayers.  Under prior
law, noncorporate taxpayers were generally taxed at a maximum rate of 28% on net
capital gain (generally, the excess of net long-term capital gain over net
short-term capital loss).  Noncorporate taxpayers are now generally taxed at a
maximum rate of 20% on net capital gain attributable to gains realized on the
sale of property held for greater than 18 months, and a maximum rate of 28% on
net capital gain attributable to gain realized on the sale of property held for
greater than one year and not more than 18 months.  The 1997 Act retains the
treatment of short term capital gain or loss (generally, gain or loss
attributable to capital assets held for 1 year or less) and did not affect the
taxation of capital gains in the hands of corporate taxpayers.

      Under the 1997 Act, the Treasury is authorized to issue regulations for
application of the reduced capital gains tax rates to pass-through entities,
including regulated investment companies, such as the Funds.  Noncorporate
shareholders of the Funds may therefore qualify for the reduced rate of tax on
capital gain dividends paid by the Funds.

                                      52

     Disposition of Fund Shares.  A disposition of Fund shares pursuant to
     --------------------------                                           
redemption (including a redemption in-kind) or exchanges will ordinarily result
in a taxable capital gain or loss, depending on the amount received for the
shares (or are deemed to receive in the case of an exchange) and the cost of the
shares.

     If a shareholder exchanges or otherwise disposes of Fund shares within 90
days of having acquired such shares and if, as a result of having acquired those
shares, the shareholder subsequently pays a reduced sales charge on a new
purchase of shares of the Fund or a different regulated investment company, the
sales charge previously incurred acquiring the Fund's shares shall not be taken
into account (to the extent such previous sales charges do not exceed the
reduction in sales charges on the new purchase) for the purpose of determining
the amount of gain or loss on the disposition, but will be treated as having
been incurred in the acquisition of such other shares.  Also, any loss realized
on a redemption or exchange of shares of the Fund will be disallowed to the
extent that substantially identical shares are acquired within the 61-day period
beginning 30 days before and ending 30 days after the shares are disposed of.

     If a shareholder receives a designated capital gain distribution (to be
treated by the shareholder as long-term capital gain) with respect to any Fund
share and such Fund share is held for six months or less, then (unless otherwise
disallowed) any loss on the sale or exchange of that Fund share will be treated
as long-term capital loss to the extent of the designated capital gain
distribution. The foregoing loss disallowance rule does not apply to losses
realized under a periodic redemption plan.

     Federal Income Tax Rates.  As of the printing of this SAI, the maximum
     ------------------------                                              
individual tax rate applicable to ordinary income is 39.6% (marginal tax rates
may be higher for some individuals to reduce or eliminate the benefit of
exemptions and deductions); the maximum individual marginal tax rate applicable
to net capital gain is 28% (however, see "Capital Gain Distributions" above);
and the maximum corporate tax rate applicable to ordinary income and net capital
gain is 35% (marginal tax rates may be higher for some corporations to reduce or
eliminate the benefit of lower marginal income tax rates).  Naturally, the
amount of tax payable by an individual or corporation will be affected by a
combination of tax laws covering, for example, deductions, credits, deferrals,
exemptions, sources of income and other matters.

     Corporate Shareholders.  Corporate shareholders of the Funds may be
     ----------------------                                             
eligible for the dividends-received deduction on dividends distributed out of a
Fund's net investment income attributable to dividends received from domestic
corporations, which, if received directly by the corporate shareholder, would
qualify for such deduction.  A Fund's distribution attributable to dividends of
a domestic corporation will only qualify for the dividends-received deduction if
(i) the corporate shareholder generally holds the Fund shares upon which the
distribution is made for at least 46 days during the 90 day period beginning 45
days prior to the date upon which the shareholder becomes entitled to the
distribution; and (ii) the Fund generally holds the shares of the domestic
corporation producing the dividend income for at least 46 days during the 90 day
period beginning 45 days prior to the date upon which the Fund becomes entitled
to the dividends.

                                      53

     Backup Withholding.  The Company may be required to withhold, subject to
     ------------------                                                      
certain exemptions, at a rate of 31% ("backup withholding") on dividends,
capital gain distributions, and redemption proceeds (including proceeds from
exchanges and redemptions in-kind) paid or credited to an individual Fund
shareholder, unless the shareholder certifies that the Taxpayer Identification
Number ("TIN") provided is correct and that the shareholder is not subject to
backup withholding, or the IRS notifies the Company that the shareholder's TIN
is incorrect or that the shareholder is subject to backup withholding.  Such tax
withheld does not constitute any additional tax imposed on the shareholder, and
may be claimed as a credit or refund on the shareholder's federal income tax
return.  An investor must provide a valid TIN upon opening or reopening an
account.  Failure to furnish a valid TIN to the Company could subject the
investor to penalties imposed by the IRS.  Foreign shareholders of the Funds
(described below) are generally not subject to backup withholding.

     Foreign Shareholders.  Under the Code, distributions of net investment
     --------------------                                                  
income by a Fund to a nonresident alien individual, foreign trust (i.e., trust
which a U.S. court is able to exercise primary supervision over administration
of that trust and one or more U.S. persons have authority to control substantial
decisions of that trust), foreign estate (i.e., the income of which is not
subject to U.S. tax regardless of source), foreign corporation, or foreign
partnership (a "foreign shareholder") will be subject to U.S. income tax
withholding (at a rate of 30% or a lower treaty rate, if applicable).
Withholding will not apply if a dividend distribution paid by a Fund to a
foreign shareholder is "effectively connected" with a U.S. trade or business
(or, if an income tax treaty applies, is attributable to a U.S. permanent
establishment of the foreign shareholder), in which case the reporting and
withholding requirements applicable to U.S. residents will apply.  Distributions
of net capital gain are generally not subject to U.S. income tax withholding.

     New Regulations.  On October 6, 1997, the Treasury Department issued new
     ---------------                                                         
regulations (the "New Regulations") which make certain modifications to the
backup withholding, U.S. income tax withholding and information reporting rules
applicable to foreign shareholders.  The New Regulations will generally be
effective for payments made after December 31, 1998, subject to certain
transition rules.  Among other things, the New Regulations will permit the Funds
to estimate the portion of their distributions qualifying as capital gain
distributions for purposes of determining the portion of such distributions paid
to foreign shareholders which will be subject to U.S. income tax withholding.
Prospective investors are urged to consult their own tax advisors regarding the
New Regulations.

     Tax-Deferred Plans.  The shares of the Funds are available for a variety of
     ------------------                                                         
tax-deferred retirement and other plans, including Individual Retirement
Accounts ("IRA"), Simplified Employee Pension Plans ("SEP-IRA"), Savings
Incentive Match Plans for Employees ("SIMPLE plans"), Roth IRAs, and Education
IRAs, which permit investors to defer some of their income from taxes. Investors
should contact their selling agents for details concerning retirement plans.

     Other Matters.  Investors should be aware that the investments to be made
     -------------                                                            
by a Fund may involve sophisticated tax rules that may result in income or gain
recognition by the Fund without corresponding current cash receipts.  Although
the Funds will seek to avoid significant noncash 

                                      54
<PAGE>
 
income, such noncash income could be recognized by a Fund, in which case the
Fund may distribute cash derived from other sources in order to meet the minimum
distribution requirements described above.

     The foregoing discussion and the discussions in the Prospectus applicable
to each shareholder address only some of the federal income tax considerations
generally affecting investments in a Fund.  Each investor is urged to consult
his or her tax advisor regarding specific questions as to federal, state, local
and foreign taxes.


                                 CAPITAL STOCK

     The Funds are four of the funds of the Stagecoach Family of Funds. The
Company was organized as a Maryland corporation on September 9, 1991 and
currently offers shares of over thirty other funds.

     Most of the Company's funds are authorized to issue multiple classes of
shares, one class generally subject to a front-end sales charge and, in some
cases, classes subject to a contingent-deferred sales charge, that are offered
to retail investors. Certain of the Company's funds also are authorized to issue
other classes of shares, which are sold primarily to institutional investors.
Each class of shares in a fund represents an equal, proportionate interest in a
fund with other shares of the same class. Shareholders of each class bear their
pro rata portion of the fund's operating expenses, except for certain class-
specific expenses (e.g., any state securities registration fees, shareholder
servicing fees or distribution fees that may be paid under Rule 12b-1) that are
allocated to a particular class. Please contact Stagecoach Shareholder Services
at 1-800-222-8222 if you would like additional information about other funds or
classes of shares offered.

     With respect to matters that affect one class but not another, shareholders
vote as a class; for example, the approval of a Plan. Subject to the foregoing,
all shares of a Fund have equal voting rights and will be voted in the
aggregate, and not by Series, except where voting by a Series is required by law
or where the matter involved only affects one Series. For example, a change in a
Funds' fundamental investment policy affects only one Series and would be voted
upon only by shareholders of the Fund involved. Additionally, approval of an
advisory contract, since it only affects one Fund, is a matter to be determined
separately by each Series. Approval by the shareholders of one Series is
effective as to that Series whether or not sufficient votes are received from
the shareholders of the other series to approve the proposal as to those Series.

     As used in the Prospectus and in this SAI, the term "majority" when
referring to approvals to be obtained from shareholders of a Class of the Fund,
means the vote of the lesser of (i) 67% of the shares of such class the Fund
represented at a meeting if the holders of more than 50% of the outstanding
shares such class of the Fund are present in person or by proxy, or (ii) more
than 50% of the outstanding shares of such class the Fund.  The term "majority,"
when referring to the approvals to be obtained from shareholders of the Company
as a whole, means the vote of the lesser of (i) 67% of the Company's shares
represented at a meeting if the holders of more than 50% of the Company's
outstanding shares are present in person or by proxy, or 

                                      55
<PAGE>
 
(ii) more than 50% of the Company's outstanding shares. Shareholders are
entitled to one vote for each full share held and fractional votes for
fractional shares held.

     Shareholders are not entitled to any preemptive rights.  All shares, when
issued for the consideration described in the Prospectus, will be fully paid and
non-assessable by the Company.  The Company may dispense with an annual meeting
of shareholders in any year in which it is not required to elect directors under
the 1940 Act.

     Each share of a class of a Fund represents an equal proportional interest
in a Fund with each other share in the same class and is entitled to such
dividends and distributions out of the income earned on the assets belonging to
a Fund as are declared in the discretion of the Directors.  In the event of the
liquidation or dissolution of the Company, shareholders of a Fund are entitled
to receive the assets attributable to the relevant class of shares of the Fund
that are available for distribution, and a distribution of any general assets
not attributable to a particular investment portfolio that are available for
distribution in such manner and on such basis as the Directors in their sole
discretion may determine.

     Set forth below as of October 31, 1997, is the name, address and share
ownership of each person known by the Company to have beneficial or record
ownership of 5% or more of a class of a Fund or 5% or more of the voting
securities of the Fund as a whole.  The term "N/A" is used where a shareholder
holds 5% or more of a class, but less than 5% of a Fund as a whole.

                      5% OWNERSHIP AS OF OCTOBER 31, 1997

                                 SAI APPENDIX

     The following is a description of the ratings given by Moody's and S&P to
corporate bonds and commercial paper.

Corporate Bonds

     Moody's:  The four highest ratings for corporate bonds are "Aaa," "Aa," "A"
and "Baa."  Bonds rated "Aaa" are judged to be of the "best quality" and carry
the smallest amount of investment risk.  Bonds rated "Aa" are of "high quality
by all standards," but margins of protection or other elements make long-term
risks appear somewhat greater than "Aaa" rated bonds.  Bonds rated "A" possess
many favorable investment attributes and are considered to be upper medium grade
obligations.  Bonds rated "Baa" are considered to be medium grade obligations;
interest payments and principal security appear adequate for the present but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time.  Such bonds have speculative
characteristics as well.  Moody's applies numerical modifiers:  1, 2 and 3 in
each rating category from "Aa" through "Baa" in its rating system.  The modifier
1 indicates that the security ranks in the higher end of its category; the
modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that the
issue ranks in the lower end.

     S&P:  The four highest ratings for corporate bonds are "AAA," "AA," "A" and
"BBB."  Bonds rated "AAA" have the highest ratings assigned by S&P and have an
extremely strong capacity to pay interest and repay principal.  Bonds rated "AA"
have a "very strong capacity to pay interest and repay principal" and differ
"from the highest rated issued only in small degree."  Bonds rated "A" have a
"strong capacity" to pay interest and repay principal, but are "somewhat more
susceptible" to adverse effects of changes in economic conditions or other
circumstances than bonds in higher rated categories.  Bonds rated "BBB" are
regarded as having an "adequate capacity" to pay interest and repay principal,
but changes in economic conditions or other circumstances are more likely to
lead to a "weakened capacity" to make such repayments.  The ratings from "AA" to
"BBB" may be modified by the addition of a plus or minus sign to show relative
standing within the category.

Corporate Commercial Paper

     Moody's:  The highest rating for corporate commercial paper is "P-1"
(Prime-1).  Issuers rated "P-1" have a "superior capacity for repayment of
short-term promissory obligations."  Issuers rated "P-2" (Prime-2) "have a
strong capacity for repayment of short-term promissory obligations," but
earnings trends, while sound, will be subject to more variation.

     S&P:  The "A-1" rating for corporate commercial paper indicates that the
"degree of safety regarding timely payment is either overwhelming or very
strong."  Commercial 

                                      A-1

paper with "overwhelming safety characteristics" will be rated "A-1+."
Commercial paper with a strong capacity for timely payments on issues will be
rated "A-2."

                                    GENERAL

     The Intermediate Bond was originally organized as an investment portfolio
of Westcore Trust ("Westcore") under the name Bonds Plus.  On October 1, 1995,
the Fund was reorganized as the Pacifica Intermediate Bond Fund, an investment
portfolio of Pacifica Funds Trust ("Pacifica").  On September 6, 1996, the
Pacifica Intermediate Bond Fund was reorganized as the Company's Intermediate
Bond Fund.

     The Institutional shares of the Short-Intermediate U.S. Government Income
and U.S. Government Income Funds commenced operations on September 6, 1996.

     On July 23, 1997, the Boards of Directors of the Company and Overland
Express Funds, Inc. ("Overland"), another investment company advised by Wells
Fargo Bank, approved an Agreement and Plan of Consolidation providing for, among
other things, the reorganization of the U.S. Government Income Fund of Overland
with and into the Company's U.S. Government Income Fund (the "Consolidation").
For accounting purposes, the Overland Fund is considered the survivor of the
Consolidation.  The Overland Fund is sometimes referred to throughout this SAI
as the "predecessor portfolio" to the Company's U.S. Government Income Fund.
Prior to December 12, 1997, the effective date of the Consolidation of the
Company and Overland, the Company's U.S. Government Income Fund was known as the
Ginnie Mae Fund.

                            INVESTMENT RESTRICTIONS

     Fundamental Investment Policies.
     ------------------------------- 

     Each Fund has adopted the following investment restrictions, all of which
are fundamental policies; that is, they may not be changed without approval by
the vote of the holders of a majority (defined in the Investment Company Act of
1940, as amended (the "1940 Act")) of the outstanding voting securities of such
Fund:

The Intermediate Bond Fund may not:

     (1)  purchase or sell commodity contracts or invest in oil, gas or mineral
exploration or development programs, except that the Fund, to the extent
appropriate to its investment objective, may purchase publicly traded securities
of companies engaging in whole or in part in such activities, and provided that
the Fund may enter into futures contracts and related options;

     (2)  purchase or sell real estate, except that the Fund may purchase
securities of issuers that deal in real estate and may purchase securities that
are secured by interests in real estate;

     (3)  purchase securities of companies for the purpose of exercising
control;

     (4)  acquire any other investment company or investment company security
except in connection with a merger, consolidation, reorganization or acquisition
of assets or where otherwise permitted by the 1940 Act;

                                       1
<PAGE>
 
     (5)  act as an underwriter of securities within the meaning of the
Securities Act of 1933 except insofar as the Fund might be deemed to be an
underwriter upon disposition of portfolio securities acquired within the
limitation on purchases of restricted securities and except to the extent that
the purchase of obligations directly from the issuer thereof in accordance with
the Fund's investment objective, policies and limitations may be deemed to be
underwriting;

     (6)  write or sell put options, call options, straddles, spreads, or any
combination thereof, except that the Fund may enter into transactions in options
on securities, futures contracts and options on futures contracts;

     (7)  borrow money or issue senior securities, except that the Fund may
borrow from banks and enter into reverse repurchase agreements for temporary
purposes in amounts up to 10% of the value of the total assets at the time of
such borrowing; or mortgage, pledge or hypothecate any assets, except in
connection with any such borrowing and in amounts not in excess of the lesser of
the dollar amounts borrowed or 10% of the value of the Fund's total assets at
the time of such borrowing.  The Fund will not purchase securities while its
borrowings (including reverse repurchase agreements) in excess of 5% of its
total assets are outstanding. Securities held in escrow or separate accounts in
connection with the Fund's investment practices described in this SAI or in its
Prospectus are not deemed to be pledged for purposes of this limitation;

     (8)  purchase securities of any one issuer (other than securities issued or
guaranteed by the U.S. Government, its agencies or instrumentalities) if,
immediately after such purchase, more than 5% of the value of the Fund's total
assets would be invested in the securities of such issuer, or more than 10% of
the issuer's outstanding voting securities would be owned by the Fund or the
Company, except that up to 25% of the value of the Fund's total assets may be
invested without regard to these limitations;

     (9)  purchase any securities that would cause 25% or more of the Fund's
total assets at the time of purchase to be invested in the securities of one or
more issuers conducting their principal business activities in the same
industry, provided that (a) there is no limitation with respect to obligations
issued or guaranteed by the U.S. Government, its agencies or instrumentalities;
(b) wholly owned finance companies will be considered to be in the industries of
their parents if their activities are primarily related to financing the
activities of the parents; and (c) utilities will be divided according to their
services, for example, gas, gas transmission, electric and gas, electric and
telephone will each be considered a separate industry;

     (10) make loans, except that the Fund may purchase and hold debt
instruments and enter into repurchase agreements in accordance with its
investment objective and policies and may lend portfolio securities in an amount
not exceeding 30% of its total assets; nor

     (11) purchase securities on margin, make short sales of securities or
maintain a short position, except that (a) this investment limitation shall not
apply to the Fund's transactions in futures contracts and related options, and
(b) the Fund may obtain short-term credit as may be necessary for the clearance
of purchases and sales of portfolio securities.

The Short-Intermediate U.S. Government Fund may not:

     (1)  purchase the securities of issuers conducting their principal business
activity in the same industry if, immediately after the purchase and as a result
thereof, the value of the Fund's investments in that industry would be 25% or
more of the current value of the Fund's total assets, provided that there is no
limitation with respect to investments in U.S. Government Obligations;

     (2)  purchase or sell real estate or real estate limited partnerships
(other than securities secured by real estate or interests therein or securities

     (6)  underwrite securities of other issuers, except to the extent that the
purchase of permitted investments directly from the issuer thereof or from an
underwriter for an issuer and the later disposition of such securities in
accordance with the Fund's investment program may be deemed to be an
underwriting;

     (7)  make investments for the purpose of exercising control or management;

     (8)  borrow money or issue senior securities as defined in the 1940 Act,
except that the Fund may borrow from banks up to 10% of the current value of its

borrowings exceed 5% of its net assets), and except that the Fund may issue
multiple Classes of shares in accordance with applicable laws, rules,
regulations or orders;

     (9)  write, purchase or sell straddles, spreads, warrants, or any
combination thereof;

     (10) purchase securities of any issuer (except U.S. Government Obligations)

value of the Fund's total assets would be invested in the securities of any one
issuer or, with respect to 100% of its total assets the Fund's ownership would

more of the current value of the Fund's total assets, provided that there is no
limitation with respect to investments in obligations of the United States
Government, its agencies or instrumentalities;

     (2)  purchase or sell real estate or real estate limited partnerships
(other than securities secured by real estate or interests therein or securities

     (6)  underwrite securities of other issuers, except to the extent that the
purchase of permitted investments directly from the issuer thereof or from an
underwriter for an issuer and the later disposition of such securities in
accordance with the Fund's investment program may be deemed to be an
underwriting;

options or any combination thereof; nor

     (10) purchase securities of any issuer (except securities issued or

result, more than 5% of the value of the Fund's total assets would be invested

     Non-Fundamental Investment Policies.
     ----------------------------------- 

     Each Fund has adopted the following non-fundamental policies which may be
changed by a majority vote of the Board of Directors of the Company at any time
and without approval of such Fund's shareholders.

     (1)  Each Fund may invest in shares of other open-end management investment
companies, subject to the limitations of Section 12(d)(1) of the 1940 Act.
Under the 1940 Act, a Fund's investment in such securities currently is limited
to, subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5%  of such Fund's net assets with respect to any one
investment company, and (iii) 10% of such Fund's net assets in the aggregate.
Other investment companies in which the Funds invest can be expected to charge
fees for operating expenses, such as investment advisory and administration
fees, that would be in addition to those charged by a Fund.

     (2)  Each Fund may not invest more than 15% of its net assets in illiquid
securities.  For this purpose, illiquid securities include, among others, (a)
securities that are illiquid by virtue of the absence of a readily available
market or legal or contractual restrictions on resale, (b) fixed time deposits
that are subject to withdrawal penalties and that have maturities of more than
seven days, and (c) repurchase agreements not terminable within seven days.

     (3)  Each Fund may invest up to 25% of its net assets in securities of
foreign governmental and foreign private issuers that are denominated in and pay
interest in U.S. dollars.

     (4)  Each Fund, except the Short-Intermediate U.S. Government Income Fund,
may lend securities from its portfolio to brokers, dealers and financial
institutions, in amounts not to exceed (in the aggregate) one-third of the U.S.
Government Income Fund's total assets and 30% of the Intermediate Bond Fund's
total assets. Any such loans of portfolio securities will be fully
collateralized based on values that are marked to market daily. The Funds will
not enter into any portfolio security lending arrangement having a duration of
longer than one year.


                  ADDITIONAL PERMITTED INVESTMENT ACTIVITIES

     Set forth below are descriptions of certain investments and additional
investment policies for the Funds.

     Asset-Backed Securities
     -----------------------

     The Funds may invest in various types of asset-backed securities.  Asset-
backed securities are securities that represent an interest in an underlying
security.  The asset-backed securities in which the Funds invest may consist of
undivided fractional interests in pools of consumer loans or receivables held in
trust. Examples include certificates for automobile receivables (CARS) and
credit card receivables (CARDS). Payments of principal and interest on these
asset-backed securities are "passed through" on a monthly or other periodic
basis to certificate holders and are typically supported by some form of credit
enhancement, such as a letter of credit, surety bond,

                                       5
<PAGE>
 
limited guaranty, or subordination. The extent of credit enhancement varies, but
usually amounts to only a fraction of the asset-backed security's par value
until exhausted. Ultimately, asset-backed securities are dependent upon payment
of the consumer loans or receivables by individuals, and the certificate holder
frequently has no recourse to the entity that originated the loans or
receivables. The actual maturity and realized yield will vary based upon the
prepayment experience of the underlying asset pool and prevailing interest rates
at the time of prepayment. Asset-backed securities are relatively new
instruments and may be subject to greater risk of default during periods of
economic downturn than other instruments. Also, the secondary market for certain
asset-backed securities may not be as liquid as the market for other types of
securities, which could result in a Fund experiencing difficulty in valuing or
liquidating such securities.

     Bank Obligations
     ----------------

     The Funds may invest in bank obligations, including certificates of
deposit, time deposits, bankers' acceptances and other short-term obligations of
domestic banks, foreign subsidiaries of domestic banks, foreign branches of
domestic banks, and domestic and foreign branches of foreign banks, domestic
savings and loan associations and other banking institutions. With respect to
such securities issued by foreign branches of domestic banks, foreign
subsidiaries of domestic banks, and domestic and foreign branches of foreign
banks, a Fund may be subject to additional investment risks that are different
in some respects from those incurred by a fund which invests only in debt
obligations of U.S. domestic issuers. Such risks include possible future
political and economic developments, the possible imposition of foreign
withholding taxes on interest income payable on the securities, the possible
establishment of exchange controls or the adoption of other foreign governmental
restrictions which might adversely affect the payment of principal and interest
on these securities and the possible seizure or nationalization of foreign
deposits. In addition, foreign branches of U.S. banks and foreign banks may be
subject to less stringent reserve requirements and to different accounting,
auditing, reporting and recordkeeping standards than those applicable to
domestic branches of U.S. banks.

     Certificates of deposit are negotiable certificates evidencing the
obligation of a bank to repay funds deposited with it for a specified period of
time.

     Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time at a stated interest rate.  Time
deposits which may be held by the Fund will not benefit from insurance from the
Bank Insurance Fund or the Savings Association Insurance Fund administered by
the Federal Deposit Insurance Corporation.  Bankers' acceptances are credit
instruments evidencing the obligation of a bank 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 face amount of the instrument upon maturity.  The other short-
term obligations may include uninsured, direct obligations, bearing fixed,
floating- or variable-interest rates.

     Bonds
     -----

     Certain of the debt instruments purchased by the Funds may be bonds. A bond
is an interest-bearing security issued by a company or governmental unit. The
issuer of a bond has a contractual obligation to pay interest at a stated rate
on specific dates and to repay principal (the

                                       6
<PAGE>
 
bond's face value) periodically or on a specified maturity date. An issuer may
have the right to redeem or "call" a bond before maturity, in which case the
investor may have to reinvest the proceeds at lower market rates. Most bonds
bear interest income at a "coupon" rate that is fixed for the life of the bond.
The value of a fixed rate bond usually rises when market interest rates fall,
and falls when market interest rates rise. Accordingly, a fixed rate bond's
yield (income as a percent of the bond's current value) may differ from its
coupon rate as its value rises or falls.

     Other types of bonds bear income at an interest rate that is adjusted
periodically. Because of their adjustable interest rates, the value of
"floating-rate" or "variable-rate" bonds fluctuates much less in response to
market interest rate movements than the value of fixed rate bonds. Also, the
Funds may treat some of these bonds as having a shorter maturity for purposes of
calculating the weighted average maturity of their investment portfolios. Bonds
may be senior or subordinated obligations. Senior obligations generally have the
first claim on a corporation's earnings and assets and, in the event of
liquidation, are paid before subordinated debt. Bonds may be unsecured (backed
only by the issuer's general creditworthiness) or secured (also backed by
specified collateral).

     Commercial Paper
     ----------------

     The Funds may invest in commercial paper (including variable amount master
demand notes) which refers to short-term, unsecured promissory notes issued by
corporations to finance short-term credit needs. Commercial paper is usually
sold on a discount basis and has a maturity at the time of issuance not
exceeding nine months. Variable amount master demand notes are demand
obligations which permit the investment of fluctuating amounts at varying market
rates of interest pursuant to arrangements between the issuer and a commercial
bank acting as agent for the payee of such notes whereby both parties have the
right to vary the amount of the outstanding indebtedness on the notes.
Investments by the Funds in commercial paper (including variable rate demand
notes and variable rate master demand notes issued by domestic and foreign bank
holding companies, corporations and financial institutions, as well as similar
instruments issued by government agencies and instrumentalities) will consist of
issues that are rated in ONE OF THE TWO HIGHEST RATING CATEGORIES BY A NRSRO.
Commercial paper may include variable- and floating-rate instruments.

     Custodial Receipts for Treasury Securities
     ------------------------------------------

     The Intermediate Bond Fund may purchase participations in trusts that hold
U.S. Treasury securities (such as TIGRs and CATS) or other obligations where the
trust participations evidence ownership in either the future interest payments
or the future principal payments on the obligations. These participations are
normally issued at a discount to their "face value," and can exhibit greater
price volatility than ordinary debt securities because of the way in which their
principal and interest are returned to investors. Investments by the Fund in
such participations will not exceed 5% of the value of the Fund's total assets.

     Derivative Securities
     ---------------------

     The Intermediate Bond and Short-Intermediate U.S. Government Income Funds
may invest in structured notes, bonds or other instruments with interest rates
that are determined by reference

                                       7
<PAGE>
 
to changes in the value of other interest rates, indices or financial reference
to changes in the value of other interest rates, indices or financial indicators
("References") or the relative change in two or more References. These Funds may
also hold derivative instruments that have interest rates that re-set inversely
to changing current market rates and/or have embedded interest rate floors and
caps that require the issuer to pay an adjusted interest rate if market rates
fall below or rise above a specified rate. These instruments represent
relatively recent innovations in the bond markets, and the trading market for
these instruments is less developed than the markets for traditional types of
debt instruments. It is uncertain how these instruments will perform under
different economic and interest-rate scenarios. Because certain of these
instruments are leveraged, their market values may be more volatile than other
types of bonds and may present greater potential for capital gain or loss. The
embedded option features of other derivative instruments could limit the amount
of appreciation a Fund can realize on its investment, could cause a Fund to hold
a security it might otherwise sell or could force the sale of a security at
inopportune times or for prices that do not reflect current market value. The
possibility of default by the issuer or the issuer's credit provider may be
greater for these structured and derivative instruments than for other types of
instruments. In some cases, it may be difficult to determine the fair value of a
structured or derivative instrument because of a lack of reliable objective
information and an established secondary market for some instruments may not
exist. As new types of derivative securities are developed and offered to
investors, the adviser will, consistent with the Fund's investment objective,
policies and quality standards, consider making investments in such new types of
derivative securities.

     Floating- and Variable-Rate Obligations
     ---------------------------------------

     The Funds may purchase floating- and  variable-rate obligations.  The Funds
may purchase floating- and variable-rate demand notes and bonds.  Variable-rate
demand notes include master demand notes that are obligations that permit the
Fund to invest fluctuating amounts, which may change daily without penalty,
pursuant to direct arrangements between the Fund, as lender, and the borrower.
The interest rates on these notes may fluctuate from time to time.  The issuer
of such obligations ordinarily has a corresponding right, after a given period,
to prepay in its discretion the outstanding principal amount of the obligations
plus accrued interest upon a specified number of days' notice to the holders of
such obligations.  The interest rate on a floating-rate demand obligation is
based on a known lending rate, such as a bank's prime rate, and is adjusted
automatically each time such rate is adjusted.  The interest rate on a variable-
rate demand obligation is adjusted automatically at specified intervals.
Frequently, such obligations are secured by letters of credit or other credit
support arrangements provided by banks.  Because these obligations are direct
lending arrangements between the lender and borrower, it is not contemplated
that such instruments generally will be traded, and there generally is no
established secondary market for these obligations, although they are redeemable
at face value.  Accordingly, where these obligations are not secured by letters
of credit or other credit support arrangements, a Fund's right to redeem is
dependent on the ability of the borrower to pay principal and interest on
demand.  Such obligations frequently are not rated by credit rating agencies and
the Fund may invest in obligations which are not so rated only if Wells Fargo
Bank determines that at the time of investment the obligations are of comparable
quality to the other obligations in which such Fund may invest. Wells Fargo
Bank, on behalf of the Fund, considers on an ongoing basis the creditworthiness
of the issuers of the floating- and variable-rate demand obligations in such
Fund's portfolio.  No Fund will invest more than 15% of the value of its total
net assets in floating- or variable-rate demand

                                       8
<PAGE>
 
obligations whose demand feature is not exercisable within seven days. Such
obligations may be treated as liquid, provided that an active secondary market
exists.

     Foreign Obligations
     -------------------

     Each Fund may invest up to 25% of its assets in high-quality, short-term
debt obligations of foreign branches of U.S. banks or U.S. branches of foreign
banks that are denominated in and pay interest in U.S. dollars. Investments in
foreign obligations involve certain considerations that are not typically
associated with investing in domestic obligations. There may be less publicly
available information about a foreign issuer than about a domestic issuer.
Foreign issuers also are not subject to the same uniform accounting, auditing
and financial reporting standards or governmental supervision as domestic
issuers. In addition, with respect to certain foreign countries, taxes may be
withheld at the source under foreign tax laws, and there is a possibility of
expropriation or confiscatory taxation, political or social instability or
diplomatic developments that could adversely affect investments in, the
liquidity of, and the ability to enforce contractual obligations with respect
to, securities of issuers located in those countries.

taxation, political or social instability or diplomatic developments that could
adversely affect investments in, the liquidity of, and the ability to enforce
contractual obligations with respect to, securities of issuers located in those
countries.

     Foreign Securities
     ------------------

     The INTERMEDIATE BOND FUND may invest in securities denominated in
currencies other than the U.S. dollar and may temporarily hold funds in bank
deposits or other money market investments denominated in foreign currencies.
Therefore, the Fund may be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rate between such currencies and the
dollar. Changes in foreign currency exchange rates influence values within a
Fund from the perspective of U.S. investors. Changes in foreign currency
exchange rates may also affect the value of dividends and interest earned, gains
and losses realized on the sale of securities, and any net investment income and
gains to be distributed to shareholders by a Fund. The rate of exchange between
the U.S. dollar and other currencies is determined by the forces of supply and
demand in the foreign exchange markets. These forces are affected by the
international balance of payments and other economic and financial conditions,
government intervention, speculation and other factors.

                                       9
<PAGE>
 
     Investments in foreign securities also involve certain inherent risks, such
as political or economic instability of the issuer or the country of issue, the
difficulty of predicting international trade patterns and the possibility of
imposition of exchange controls. Such securities may also be subject to greater
fluctuations in price than securities of domestic corporations. In addition,
there may be less publicly available information about a foreign company than
about a domestic company. Foreign companies generally are not subject to uniform
accounting, auditing and financial reporting standards comparable to those
applicable to domestic companies.  Investments in foreign securities and forward
contracts may also be subject to withholding and other taxes imposed by foreign
governments.  With respect to certain foreign countries, there is also a
possibility of expropriation or confiscatory taxation, or diplomatic
developments which could affect investments in those countries.

     Forward Commitment, When-Issued and Delayed-Delivery Transactions
     -----------------------------------------------------------------

     The Funds may purchase or sell securities on a when-issued or delayed
delivery basis and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time.  Delivery and payment
on such transaction normally take place within 45 DAYS after the date of the
commitment to purchase.  Securities purchased or sold on a when-issued, delayed-
delivery or forward commitment basis involve a risk of loss if the value of the
security to be purchased declines, or the value of the security to be sold
increases, before the settlement date.  Although each Fund will generally
purchase securities with the intention of acquiring them, a Fund may dispose of
securities purchased on a when-issued, delayed-delivery or a forward commitment
basis before settlement when deemed appropriate by the adviser.

     The Funds will establish a segregated account in which they will maintain
cash, U.S. Government obligations or other high-quality debt instruments in an
amount at least equal in value to each such Fund's commitments to purchase when-
issued securities. If the value of these assets declines, a Fund will place
additional liquid assets in the account on a daily basis so that the value of
the assets in the account is equal to the amount of such commitments.

     Illiquid Securities
     -------------------

     The Funds may invest in securities not registered under the 1933 Act and
other securities subject to legal or other restrictions on resale. Because such
securities may be less liquid than other investments, they may be difficult to
sell promptly at an acceptable price. Delay or difficulty in selling securities
may result in a loss or be costly to a Fund.  Each Fund may invest up to 15% of
its net assets in illiquid securities.

     Loans of Portfolio Securities
     -----------------------------

     Each Fund may lend its portfolio securities to brokers, dealers and
financial institutions, provided: (1) the loan is secured continuously by
collateral consisting of U.S. Government securities or cash or letters of credit
maintained on a daily marked-to-market basis in an amount at least equal to the
current market value of the securities loaned; (2) the Fund may at any time call
the loan and obtain the return of the securities loaned within five business
days; (3) the Fund will receive any interest or dividends paid on the loaned
securities; and (4) the aggregate market value

                                      10
<PAGE>
 
of securities loaned will not at any time exceed one third (30% for the
Intermediate Bond Fund) of the total assets of a particular Fund.

     A Fund will earn income for lending its securities because cash collateral
pursuant to these loans will be invested in short-term money market instruments.
In connection with lending securities, a Fund may pay reasonable finders,
administrative and custodial fees.  A Fund will not enter into any security
lending arrangement having a duration longer than one year.  Loans of securities
involve a risk that the borrower may fail to return the securities or may fail
to provide additional collateral. In either case, a Fund could experience delays
in recovering securities or collateral or could lose all or part of the value of
the loaned securities.  When a Fund lends its securities, it continues to
receive interest or dividends on the securities loaned and may simultaneously
earn interest on the collateral received from the borrower or from the
investment of cash collateral in readily marketable, high-quality, short-term
obligations. Although voting rights, or rights to consent, attendant to
securities on loan pass to the borrower, such loans may be called at any time
and will be called so that the securities may be voted by a Fund if a material
event affecting the investment is to occur.  A Fund may pay a portion of the
interest or fee earned from securities lending to a borrower or a placing
broker.  Borrowers and placing brokers may not be affiliated, directly or
indirectly with Wells Fargo Bank, Stephens Inc. or any of their affiliates.

     Mortgage-Related Securities
     ---------------------------

     The Funds may invest in mortgage-related securities. Mortgage pass-through
securities are securities representing interests in "pools" of mortgages in
which payments of both interest and principal on the securities are made
monthly, in effect "passing through" monthly payments made by the individual
borrowers on the residential mortgage loans which underlie the securities (net
of fees paid to the issuer or guarantor of the securities).  The stated
maturities of pass-through obligations may be shortened by unscheduled
prepayments of principal on the underlying mortgages.  Therefore, it is not
possible to predict accurately the average maturity of a particular pass-through
obligation.  Variations in the maturities of pass-through obligations will
affect the yield of the Fund.  Early repayment of principal on mortgage pass-
through securities (arising from prepayments of principal due to sale of the
underlying property, refinancing, or foreclosure, net of fees and costs which
may be incurred) may expose a Fund to a lower rate of return upon reinvestment
of principal. Also, if a security subject to prepayment has been purchased at a
premium, in the event of prepayment the value of the premium would be lost. Like
other fixed-income securities, when interest rates rise, the value of a
mortgage-related security generally will decline; however, when interest rates
decline, the value of mortgage-related securities with prepayment features may
not increase as much as other fixed-income securities. Payment of principal and
interest on some mortgage pass-through securities (but not the market value of
the securities themselves) may be guaranteed by the full faith and credit of the
U.S. Government or its agencies or instrumentalities. Mortgage pass-through
securities created by non- government issuers (such as commercial banks, savings
and loan institutions, private mortgage insurance companies, mortgage bankers
and other secondary market issuers) may be supported by various forms of
insurance or guarantees, including individual loan, title, pool and hazard
insurance, and letters of credit, which may be issued by governmental entities,
private insurers or the mortgage poolers.

                                      11
<PAGE>
 
     These Funds may also invest in investment grade Collateralized Mortgage
Obligations ("CMOs"). CMOs may be collateralized by whole mortgage loans but are
more typically collateralized by portfolios of mortgage pass-through securities
guaranteed by GNMA, FHLMC or FNMA. CMOs are structured into multiple classes,
with each class bearing a different stated maturity. Payments of principal,
including prepayments, are first returned to investors holding the shortest
maturity class; investors holding the longer maturity classes receive principal
only after the first class has been retired. As new types of mortgage-related
securities are developed and offered to investors, the Adviser will, consistent
with the Fund's investment objective, policies and quality standards, consider
making investments in such new types of mortgage-related securities.

     Adjustable Rate Mortgages ("ARMs") and Collateralized Mortgage Obligations
("CMOs").  The Short-Intermediate U.S. Government Income Fund may invest in ARMS
issued or guaranteed by the Government National Mortgage Association ("GNMA"),
Federal National Mortgage Association ("FNMA") or the Federal Home Loan Mortgage
Corporation ("FHLMC").  The full and timely payment of principal and interest on
GNMA ARMS is guaranteed by GNMA and backed by the full faith and credit of the
U.S. Government. FNMA also guarantees full and timely payment of both interest
and principal, while FHLMC guarantees full and timely payment of interest and
ultimate payment of principal. FNMA and FHLMC ARMS are not backed by the full
faith and credit of the United States. However, because FNMA and FHLMC are
government-sponsored enterprises, these securities are generally considered to
be high quality investments that present minimal credit risks. The yields
provided by these ARMS have historically exceeded the yields on other types of
U.S. Government securities with comparable maturities, although there can be no
assurance that this historical performance will continue.

     The mortgages underlying ARMS guaranteed by GNMA are typically insured or
guaranteed by the Federal Housing Administration, the Veterans Administration or
the Farmers Home Administration, while those underlying ARMS issued by FNMA or
FHLMC are typically conventional residential mortgages which are not so insured
or guaranteed, but which conform to specific underwriting, size and maturity
standards.

     In a CMO, a series of bonds or certificates is issued in multiple classes.
Each class of CMOs, often referred to as a "tranche," is issued at a specified
coupon rate and has a stated maturity or final distribution date. The principal
and interest payment on the underlying mortgages may be allocated among the
classes of CMOs in several ways. Typically, payments of principal, including any
prepayments, on the underlying mortgages are applied to the classes in the order
of their respective stated maturities or final distribution dates, so that no
payment of principal is made on CMOs of a class until all CMOs of other classes
having earlier stated maturities or final distribution dates have been paid in
full. One or more classes of CMOs may have coupon rates that reset periodically
based on an index, such as the London Interbank Offered Rate ("LIBOR").

     The interest rates on the mortgages underlying the ARMS and some of the
CMOs in which the Short-Intermediate U.S. Government Income Fund may invest
generally are readjusted at periodic intervals ranging from one year or less to
several years in response to changes in a predetermined interest rate index.
There are two main categories of indices: those based on U.S. Treasury
securities and those derived from a calculated measure, such as a cost-of-funds
index or a

                                      12
<PAGE>
 
moving average of mortgage rates. Commonly utilized indices include the one-year
and five-year constant maturity Treasury note rates, the three-month Treasury
bill rate, the 180-day Treasury bill rate, rates on longer-term Treasury
securities, the National Median Cost of Funds, the one-month, three-month, six-
month or one-year LIBOR, a published prime rate or commercial paper rates.
Certain of these indices follow overall market interest rates more closely than
others.

     Adjustable rate mortgages, an increasingly common form of residential
financing, generally have a specified maturity date. Most provide for
amortization of principal in a manner similar to fixed-rate mortgages, but have
interest rates that change in response to changes in a specified interest rate
index. The rate of interest due on such a mortgage is calculated by adding an
agreed-upon "margin" to the specified index, although there generally are
limitations or "caps" on interest rate movements in any given period or over the
life of the mortgage. To the extent that the interest rates on adjustable rate
mortgages cannot be adjusted in response to interest rate changes because of
interest rate caps, the ARMS or CMOs backed by such mortgages are likely to
respond to changes in market rates more like fixed rate securities. In other
words, interest rate increases in excess of such caps can be expected to cause
CMOs or ARMS backed by mortgages that have such caps to decline in value to a
greater extent than would be the case in the absence of such caps. Conversely,
interest rate decreases below interest rate floors can be expected to cause the
CMOs or ARMS backed by mortgages that have such floors to increase in value to a
greater extent than would be the case in the absence of such floors.

     These adjustable rate features should reduce, but will not eliminate, price
fluctuations in such securities, particularly when market interest rates
fluctuate.  Since the interest rates on mortgages typically are reset at most
annually and generally are subject to caps, it can be expected that the prices
of ARMS and CMOs backed by such mortgages will fluctuate to the extent
prevailing market interest rates are not reflected in the interest rates payable
on the underlying adjustable rate mortgages. In this regard, the net asset value
of a Fund's shares could fluctuate to the extent interest rates on underlying
mortgages differ from prevailing market interest rates during interim periods
between interest rate reset dates. Accordingly, investors could experience some
principal loss or less gain than might otherwise be achieved if they redeem
their shares of a Fund or if the Fund sells these portfolio securities before
the interest rates on the underlying mortgages are adjusted to reflect
prevailing market interest rates.

     The holder of ARMS and certain CMOs receives not only monthly scheduled
payments of principal and interest, but also may receive unscheduled principal
payments representing prepayments on the underlying mortgages. Changes in market
interest rates and interest rate indexes can affect these prepayment rates,
thereby shortening or lengthening their duration, the holder therefore, may have
to reinvest the periodic payments and any unscheduled prepayments of principal
it receives at a rate of interest which is lower than the rate on the ARMS and
CMOs held by it.

     CMOs backed by fixed rate mortgages share many of the rate, duration and
investment risks described above because of their contractual and investment
features and because of factors such as the prepayment rates on the underlying
fixed rate mortgages.

                                      13
<PAGE>
 
     The SHORT-INTERMEDIATE U.S. GOVERNMENT INCOME Fund will not invest in CMOs
that, at the time of purchase, are "high-risk mortgage securities" as defined in
the then current Federal Financial Institutions Examination Council Supervisory
Policy Statement on Securities Activities (the "FFIEC Policy Statement"). Under
the FFIEC Policy Statement, a CMO qualifies as a "high-risk mortgage security"
if it meets an Average Life Test, an Average Life Sensitivity Test, or a Price
Sensitivity Test. A CMO meets the Average Life Test if it has an expected
weighted average life greater than 10 years. A CMO meets the Average Life
Sensitivity Test if the expected weighted average life of the CMO either (i)
extends by more than 4 years, assuming an immediate and sustained parallel shift
in the yield curve of plus 300 basis points, or (ii) shortens by more than 6
years, assuming an immediate and sustained parallel shift in the yield curve of
minus 300 basis points. A CMO meets the Price Sensitivity Test if an immediate
and sustained parallel shift in the yield curve of plus or minus 300 basis
points would result in an estimated change in the price of the CMO of more than
17 percent. Under the FFIEC Policy Statement, a CMO floating-rate debt class,
i.e., a CMO the rate of which adjusts at least annually on a one-for-one basis
with a conventional, widely used market interest rate index (such as the London
Interbank Offered Rate), will not be subject to the Average Life and Average
Life Sensitivity Tests if it bears a rate that is below the contractual cap on
the instrument.

     Mortgage Participation Certificates.  The U.S. Government Income Funds also
may invest in the following types of FHLMC mortgage pass-through securities.
FHLMC issues two types of mortgage pass-through securities: 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 of mortgages. GMCs also represent a pro rata interest in a pool of
mortgages. These instruments, however, pay interest semiannually and return
principal once a year in guaranteed minimum payments.  These mortgage pass-
through securities differ from bonds in that principal is paid back by the
borrower over the length of the loan rather than returned in a lump sum at
maturity. They are called "pass-through" securities because both interest and
principal payments, including prepayments, are passed through to the holder of
the security.

     The payment of principal on the underlying mortgages may exceed the minimum
required by the schedule of payments for the mortgages. Such prepayments are
made at the option of the mortgagors for a wide variety of reasons reflecting
their individual circumstances. For example, mortgagors may speed up the rate at
which they prepay their mortgages when interest rates decline sufficiently to
encourage refinancing.  The Fund, when such prepayments are passed through to
it, may be able to reinvest them only at a lower rate of interest.  As a result,
if the Fund purchases such securities at a premium, a prepayment rate that is
faster than expected will reduce yield to maturity, while a prepayment rate that
is slower than expected will have the opposite effect of increasing yield to
maturity.  Conversely, if the Fund purchased such securities at a discount,
faster than expected prepayments will increase, while slower than expected
prepayments will reduce, yield to maturity. Accelerated prepayments on
securities purchased by the Fund at a premium also impose a risk of loss of
principal because the premium may not have been fully amortized at the time the
principal is repaid in full. In choosing specific issues, Wells Fargo Bank, as
investment adviser, will have made assumptions about the likely speed of
prepayment. Actual experience may vary from this assumption resulting in a
higher or lower investment return than anticipated.

     Municipal Obligations
     ---------------------

     The municipal obligations in which the Intermediate Bond Fund may invest
include debt obligations issued by governmental entities to obtain funds for
various public purposes, including the construction of a wide range of public
facilities, the refunding of outstanding obligations, the payment of general
operating expenses and the extension of loans to public institutions and
facilities.

     The two principal classifications of municipal obligations that may be held
by the Fund are "general obligation" securities and "revenue" securities.
General obligation securities are secured by the issuer's pledge of its full
faith, credit and taxing power for the payment of principal and interest.
Revenue securities are payable only from the revenues derived from a particular
facility or class of facilities or, in some cases, from the proceeds of a
special excise tax or other specific revenue source such as the issuer of the
facility being financed.  The Fund's portfolio may also include "moral
obligation" securities, which are issued normally by special purpose public
authorities. If the issuer of moral obligation securities is unable to meet its
debt service obligations from current revenues, it may draw on a reserve fund,
the restoration of which is a moral commitment but not a legal obligation of the
state or municipality that created the issuer.

     There are, of course, variations in the quality of municipal obligations
both within a particular classification and between classifications, and the
yields on municipal obligations depend upon a variety of factors, including
general money market conditions, the financial condition of the issuer, general
conditions of the municipal bond market, the size of a particular offering, the
maturity of the obligation and the rating of the issue.

     Private activity bonds are issued to obtain funds to provide privately
operated housing facilities, pollution control facilities, convention or trade
show facilities, mass transit, airport, port or parking facilities and certain
local facilities for water supply, gas, electricity or sewage or solid waste
disposal.  State and local governments are authorized in most states to issue
private activity bonds for such purposes in order to encourage corporations to
locate within their communities. Private activity bonds are in most cases
revenue securities and are not payable from the unrestricted revenues of the
issuer.  Private activity bonds include industrial development bonds, which  are
a specific type of revenue bond backed by the credit and security of a private
user.   The credit quality of such bonds is usually directly related to the
credit standing of the corporate user of the facility involved. Private activity
bonds issued by or on behalf of public authorities to finance various privately
operated facilities are considered municipal obligations if the interest
received thereon is exempt from federal income tax but nevertheless subject to
the federal alternative minimum tax.  Assessment bonds, wherein a specially
created district or project area levies a tax (generally on its taxable
property) to pay for an improvement or project may be considered a variant of
either category.  There are, of course, other variations in the types of
municipal bonds, both within a particular classification and between
classifications, depending on numerous factors.  Some or all of these bonds may
be considered "private activity bonds" for federal income tax purposes.

                                      15
<PAGE>
 
     The adviser, under the supervision of the Board, makes determinations
concerning the liquidity of a municipal lease obligation based on all relevant
factors. These factors may include, among others: (1) the frequency of trades
and quotes for the obligation; (2) the number of dealers willing to purchase or
sell the security and the number of other potential buyers; (3) the willingness
of dealers to undertake to make a market in the security; and (4) the nature of
the marketplace trades, including the time needed to dispose of the security,
the method of soliciting offers, and the mechanics of transfer. In addition, the
general credit quality of the municipality and the essentiality to the
municipality of the property covered by the lease may be considered. In
evaluating the credit quality of a municipal lease obligation, the factors to be
considered might include: (1) whether the lease can be canceled; (2) what
assurance there is that the assets represented by the lease can be sold; (3) the
strength of the lessee's general credit (e.g., its debt, administrative,
economic, and financial characteristics); (4) the likelihood that the
municipality will discontinue appropriating funding for the leased property
because the property is no longer deemed essential to the operations of the
municipality (e.g., the potential for an "event of the nonappropriation"); and
(5) the legal recourse in the event of failure to appropriate.

     From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on municipal obligations. For example, under federal tax legislation
enacted in 1986, interest on certain private activity bonds must be included in
an investor's alternative minimum taxable income, and corporate investors must
treat all tax-exempt interest as an item of tax preference.

     Opinions relating to the validity of municipal obligations and to the
exemption of interest thereon from federal income tax are rendered by bond
counsel to the respective issuers at the time of issuance. Neither the Fund nor
the adviser will review the proceedings relating to the issuance of municipal
obligations or the basis for such opinions.

     Certain of the municipal obligations held by the Intermediate Bond Fund may
be insured as to the timely payment of principal and interest. The insurance
policies usually are obtained by the issuer of the municipal obligation at the
time of its original issuance. In the event that the issuer defaults on interest
or principal payment, the insurer will be notified and will be required to make
payment to the bondholders. There is, however, no guarantee that the insurer
will meet its obligations. In addition, such insurance does not protect against
market fluctuations caused by changes in interest rates and other factors.

     The values of outstanding municipal securities will vary as a result of
changing market evaluations of the ability of their issuers to meet the interest
and principal payments (i.e., credit risk).  Such values also will change in
response to changes in the interest rates payable on new issues of municipal
securities (i.e., market risk).  Should such interest rates rise, the values of
outstanding securities, including those held in the Fund's portfolio, will
decline and (if purchased at par value) sell at a discount.  If interests rates
fall, the values of outstanding securities will generally increase and (if
purchased at par value) sell at a premium.  Changes in the value of municipal
securities held in the Fund's portfolio arising from these or other factors will
cause changes in the net asset value per share of the Fund.  Dividends paid by
the Fund that are derived

                                      16

from interest on municipal obligations may be taxable to shareholders for
federal income tax purposes.

     Options Trading
     ---------------

     The Intermediate Bond Fund may purchase put and call options listed on a
national securities exchange and issued by the Options Clearing Corporation in
an amount not exceeding 5% of its net assets.  Purchasing options is a
specialized investment technique that entails a substantial risk of a complete
loss of the amounts paid as premiums to the writer of the option.  Options may
be more volatile than the underlying instruments, and therefore, on a percentage
basis, an investment in options may be subject to greater fluctuation than an
investment in the underlying instruments themselves.

     The Intermediate Bond Fund may also write covered call and secured put
options from time to time as the adviser deems appropriate.  By writing a
covered call option, the Intermediate Bond Fund forgoes the opportunity to
profit from an increase in the market of the underlying security above the
exercise price except insofar as the premium represents such a profit, and it is
not able to sell the underlying security until the option expires or is
exercised or the Fund effects a closing purchase transaction by purchasing an
option of the same series.  If the Intermediate Bond Fund writes a secured put
option, it assumes the risk of loss should the market value of the underlying
security decline below the exercise price of the option.  The aggregate value of
the securities subject to options written by the Intermediate Bond Fund will not
exceed 25% of the value of its net assets.  The use of covered call options and
securities put options will not be a primary investment technique of the
Intermediate Bond Fund, and they are expected to be used infrequently.  If the
adviser is incorrect in its forecast of market value or other factors when
writing the foregoing options, the Fund would be in a worse position than it
would have been had the foregoing investment techniques not been used.

     A call option for a particular security gives the purchaser of the option
the right to buy, and a writer the obligation to sell, the underlying security
at the stated exercise price at any time prior to the expiration of the option,
regardless of the market price of the security. The premium paid to the writer
is in consideration for undertaking the obligation under the option contract. A
put option for a particular security gives the purchaser the right to sell the
security at the stated exercise price at any time prior to the expiration date
of the option, regardless of the market price of the security. Options on
indices provide the holder with the right to make or receive a cash settlement
upon exercise of the option. With respect to options on indices, the amount of
the settlement equals the difference between the closing price of the index at
the time of exercise and the exercise price of the option expressed in dollars,
times a specified multiple.

     The Intermediate Bond Fund will write call options only if they are
"covered." In the case of a call option on a security or currency, the option is
"covered" if the Fund owns the instrument underlying the call or has an absolute
and immediate right to acquire that instrument without additional cash
consideration (or, if additional cash consideration is required, cash, U.S.
Government securities or other liquid high grade debt obligations, in such
amount are held in a segregated account by the Fund's custodian) upon conversion
or exchange of other securities held

                                      17
<PAGE>
 
by it. For a call option on an index, the option is covered if the Fund
maintains with its custodian a diversified portfolio of securities comprising
the index or liquid assets equal to the contract value. A call option is also
covered if the Fund holds a call on the same instrument or index as the call
written where the exercise price of the call held is (i) equal to or less than
the exercise price of the call written, or (ii) greater than the exercise price
of the call written provided the difference is maintained by the Fund in liquid
assets in a segregated account with its custodian. The Fund will write put
options only if they are "secured" by liquid assets maintained in a segregated
account by the Fund's custodian in an amount not less than the exercise price of
the option at all times during the option period.

     The Intermediate Bond Fund's obligation to sell an instrument subject to a
covered call option written by it, or to purchase an instrument subject to a
secured put option written by it, may be terminated prior to the expiration date
of the option by the Fund's execution of a closing purchase transaction, which
is effected by purchasing on an exchange an option of the same series (i.e.,
same underlying instrument, exercise price and expiration date) as the option
previously written. Such a purchase does not result in the ownership of an
option. A closing purchase transaction is ordinarily effected to realize a
profit on an outstanding option, to prevent an underlying instrument from being
called, to permit the sale of the underlying instrument or to permit the writing
of a new option containing different terms on such underlying instrument. The
cost of such a liquidation purchase plus transaction costs may be greater than
the premium received upon the original option, in which event the Fund will have
incurred a loss in the transaction. There is no assurance that a liquid
secondary market will exist for any particular option. An option writer, unable
to effect a closing purchase transaction, will not be able to sell the
underlying instrument (in the case of a covered call option) or liquidate the
segregated account (in the case of a secured put option) until the option
expires or the optioned instrument or currency is delivered upon exercise with
the result that the writer in such circumstances will be subject to the risk of
market decline or appreciation in the instrument during such period.

     When the Fund purchases an option, the premium paid by it is recorded as an
asset of the Fund. When the Fund writes an option, an amount equal to the net
premium (the premium less the commission) received by the Fund is included in
the liability section of the Fund's statement of assets and liabilities as a
deferred credit. The amount of this asset or deferred credit will be
subsequently marked-to-market to reflect the current value of the option
purchased or written. The current value of the traded option is the last sale
price or, in the absence of a sale, the current bid price. If an option
purchased by a Fund expires unexercised the Fund realizes a loss equal to the
premium paid. If a Fund enters into a closing sale transaction on an option
purchased by it, the Fund realizes a gain if the premium received by the Fund on
the closing transaction is more than the premium paid to purchase the option, or
a loss if it is less. If an option written by a Fund expires on the stipulated
expiration date or if a Fund enters into a closing purchase transaction, it
realizes a gain (or loss if the cost of a closing purchase transaction exceeds
the net premium received when the option is sold) and the deferred credit
related to such option is eliminated. If an option written by a Fund is
exercised, the proceeds of the sale are increased by the net premium originally
received and the Fund  realizes a gain or loss.

                                      18

     There are several risks associated with transactions in options. For
example, there are significant differences between the securities, currency and
options markets that could result in an imperfect correlation between these
markets, causing a given transaction not to achieve its objectives. In addition,
a liquid secondary market for particular options, whether traded over-the-
counter or on an exchange, may be absent for reasons that include the following:
there may be insufficient trading interest in certain options; restrictions may
be imposed by an exchange on opening transactions or closing transactions or
both; trading halts, suspensions or other restrictions may be imposed with
respect to particular classes or series of options or underlying securities or
currencies; unusual or unforeseen circumstances may interrupt normal operations
on an exchange; the facilities of an exchange or the Options Clearing
Corporation may not be adequate at all times  to handle current trading value;
or one or more exchanges could, for economic or other reasons, decide or be
compelled at some future date to discontinue the trading of options (or a
particular class or series of options), in which event the secondary market on
that exchange (or in that class or series of options) would cease to exist,
although outstanding options that had been issued by the Options Clearing
Corporation as a result of trades on that exchange would continue to be
exercisable in accordance with their terms. The Fund is likely to be unable to
control losses by closing its position where a liquid secondary market does not
exist. A decision as to whether, when and how to use options involves the
exercise of skill and judgment, and even a well-conceived transaction may be
unsuccessful to some degree because of market behavior or unexpected events.

     Other Investment Companies
     --------------------------

     The Funds may invest in shares of other open-end management investment
companies, up to the limits prescribed in Section 12(d) of the 1940 Act.  Under
the 1940 Act, a Fund's investment in such securities currently is limited to,
subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5% of such Fund's net assets with respect to any one
investment company and (iii) 10% of such Fund's net assets in aggregate.  Other
investment companies in which the Funds invest can be expected to charge fees
for operating expenses such as investment advisory and administration fees, that
would be in addition to those charged by the Funds.

     Stripped Obligations
     --------------------

     The Funds may purchase Treasury receipts and other "stripped" securities
that evidence ownership in either the future interest payments or the future
principal payments on U.S. Government and other obligations. These
participations, which may be issued by the U.S. Government (or a U.S. Government
agency or instrumentality) or by private issuers such as banks and other
institutions, are issued at a discount to their "face value," and may include
stripped mortgage-backed securities ("SMBS"). Stripped securities, particularly,
SMBS, may exhibit greater price volatility than ordinary debt securities because
of the manner in which their principal and interest are returned to investors.

     Temporary Investments
     ---------------------

     The Funds may hold a certain portion of its assets in cash or short-term
investments in order to maintain adequate liquidity for redemption requests or
other cash management needs or for

                                      19
<PAGE>
 
temporary defensive purposes during periods of unusual market volatility. The
short-term investments that the Funds may purchase include, among other things,
U.S. government obligations, shares of other mutual funds, repurchase
agreements, obligations of domestic banks and short-term obligations of foreign
banks, corporations and other entities. Some of these short-term investments are
described below.

     Letters of Credit.  Certain of the debt obligations (including certificates
of participation, commercial paper and other short-term obligations) which the
Funds may purchase may be backed by an unconditional and irrevocable letter of
credit of a bank, savings and loan association or insurance company which
assumes the obligation for payment of principal and interest in the event of
default by the issuer.  Only banks, savings and loan associations and insurance
companies which, in the opinion of Wells Fargo Bank, are of comparable quality
to issuers of other permitted investments of such Fund may be used for letter of
credit-backed investments.

     Repurchase Agreements.  Each Fund may enter into repurchase agreements,
wherein the seller of a security to the Fund agrees to repurchase that security
from the Fund at a mutually agreed upon time and price.  A Fund may enter into
repurchase agreements only with respect to securities that could otherwise be
purchased by the Fund.  All repurchase agreements will be fully collateralized
at 102% based on values that are marked to market daily.  The maturities of the
underlying securities in a repurchase agreement transaction may be greater than
twelve months, although the maximum term of a repurchase agreement will always
be less than twelve months.  If the seller defaults and the value of the
underlying securities has declined, a Fund may incur a loss.  In addition, if
bankruptcy proceedings are commenced with respect to the seller of the security,
the Fund's disposition of the security may be delayed or limited.

     A Fund may not enter into a repurchase agreement with a maturity of more
than seven days, if, as a result, more than 15% of the market value of such
Fund's total net assets would be invested in repurchase agreements with
maturities of more than seven days, restricted securities and illiquid
securities.  A Fund will only enter into repurchase agreements with primary
broker/dealers and commercial banks that meet guidelines established by the
Board of Directors and that are not affiliated with the investment adviser.  The
Funds may participate in pooled repurchase agreement transactions with other
funds advised by Wells Fargo Bank.

     Borrowing and Reverse Repurchase Agreements.  The INTERMEDIATE BOND FUND
intends to limit its borrowings (including reverse repurchase agreements) during
the current fiscal year to not more than 10% of its net assets.  At the time the
Fund enters into a reverse repurchase agreement (an agreement under which the
Fund sells portfolio securities and agrees to repurchase them at an agreed-upon
date and price), it will place in a segregated custodial account liquid assets
such as U.S. Government securities or other liquid high-grade debt securities
having a value equal to or greater than the repurchase price (including accrued
interest) and will subsequently monitor the account to ensure that such value is
maintained. Reverse repurchase agreements involve the risk that the market value
of the securities sold by the Fund may decline below the price at which the Fund
is obligated to repurchase the securities. Reverse repurchase agreements are
considered to be borrowings under the 1940 Act.

                                      20

     Unrated Investments
     -------------------

     The U.S. GOVERNMENT INCOME Fund may purchase instruments that are not rated
if, in the opinion of Wells Fargo Bank, such obligations are of investment
quality comparable to other rated investments that are permitted to be purchased
by such Fund.  After purchase by the Fund, a security may cease to be rated or
its rating may be reduced below the minimum required for purchase by the Fund.
Neither event will require a sale of such security by the Fund.  To the extent
the ratings given by Moody's or S&P may change as a result of changes in such
organizations or their rating systems, the Fund will attempt to use comparable
ratings as standards for investments in accordance with the investment policies
contained in its Prospectus and in this SAI.  The ratings of Moody's and S&P are
more fully described in the SAI Appendix.

     U.S. Government Obligations
     ---------------------------

     The Funds may invest in obligations issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government Obligations").
Payment of principal and interest on U.S. Government Obligations (i) may be
backed by the full faith and credit of the United States (as with U.S. Treasury
bills and GNMA certificates) or (ii) may be backed solely by the issuing or
guaranteeing agency or instrumentality itself (as with FNMA notes). In the
latter case investors must look principally to the agency or instrumentality
issuing or guaranteeing the obligation for ultimate repayment, which agency or
instrumentality may be privately owned. There can be no assurance that the U.S.
Government will provide financial support to its agencies or instrumentalities
where it is not obligated to do so. In addition, U.S. Government Obligations are
subject to fluctuations in market value due to fluctuations in market interest
rates. As a general matter, the value of debt instruments, including U.S.
Government Obligations, declines when market interest rates increase and rises
when market interest rates decrease. Certain types of U.S. Government
Obligations are subject to fluctuations in yield or value due to their structure
or contract terms.

     Nationally Recognized Statistical Ratings Organizations
     -------------------------------------------------------

     The ratings of Moody's Investors Service, Inc., Standard & Poor's Ratings
Group, Division of McGraw Hill, Duff & Phelps Credit Rating Co., Fitch Investors
Service, Inc. Thomson Bank Watch and IBCA Inc. represent their opinions as to
the quality of debt securities. It should be emphasized, however, that ratings
are general and not absolute standards of quality, and debt securities with the
same maturity, interest rate and rating may have different yields while debt
securities of the same maturity and interest rate with different ratings may
have the same yield. Subsequent to purchase by the Intermediate Bond Fund, an
issue of debt securities may cease to be rated or its rating may be reduced
below the minimum rating required for purchase by the Fund. The adviser will
consider such an event in determining whether the Fund involved should continue
to hold the obligation.

     The payment of principal and interest on debt securities purchased by a
Fund depends upon the ability of the issuers to meet their obligations. An
issuer's obligations under its debt securities are subject to the provisions of
bankruptcy, insolvency, and other laws affecting the rights and remedies of
creditors, such as the Federal Bankruptcy Code, and laws, if any, which may be

                                      21
<PAGE>
 
enacted by federal or state legislatures extending the time for payment of
principal or interest, or both, or imposing other constraints upon enforcement
of such obligations or, in the case of governmental entities, upon the ability
of such entities to levy taxes. The power or ability of an issuer to meet its
obligations for the payment of interest and principal of its debt securities may
be materially adversely affected by litigation or other conditions. Further, it
should also be, noted with respect to all municipal obligations issued after
August 15, 1986 (August 31, 1986 in the case of certain bonds), the issuer must
comply with certain rules formerly applicable only to "industrial development
bonds" which, if the issuer fails to observe them, could cause interest on the
municipal obligations to become taxable retroactive to the date of issue.

                                 RISK FACTORS

     Investments in a Fund are not bank deposits or obligations of Wells Fargo
Bank, are not insured by the FDIC and are not insured against loss of principal.
When the value of the securities that a Fund owns declines, so does the value of
your Fund shares. You should be prepared to accept some risk with the money you
invest in a Fund.

     The portfolio debt instruments of a Fund also may be subject to credit and
interest rate risk. Credit risk is the risk that the issuers of securities in
which a Fund invests may default in the payment of principal and/or interest.
Interest rate risk is the risk that increases in market interest rates may
adversely affect the value of the debt instruments in which a Fund invests and
hence the value of your investment in a Fund.

     The market value of a Fund's investments in fixed-income securities will
change in response to various factors, such as changes in market interest rates
and the relative financial strength of an issuer.  During periods of falling
interest rates, the value of fixed-income securities generally rises.
Conversely, during periods of rising interest rates, the value of such
securities generally declines. Debt securities with longer maturities, which
tend to produce higher yields, are subject to potentially greater price
fluctuation than obligations with shorter maturities. Fluctuations in the market
value of fixed-income securities can be reduced, but not eliminated, by variable
rate or floating rate features. In addition, some of the asset-backed securities
in which the Funds invest are subject to extension risk. This is the risk that
when interest rates rise, prepayments of the underlying obligations slow,
thereby lengthening the duration and potentially reducing the value of these
securities.

     Although some of the Funds' portfolio securities are guaranteed by the U.S.
Government, its agencies or instrumentalities, such securities are subject to
interest rate risk and the market value of these securities, upon which the
Funds' daily net asset value are based, will fluctuate. No assurance can be
given that the U.S. Government would provide financial support to its agencies
or instrumentalities where it is not obligated to do so.

     Although GNMA securities are guaranteed by the U.S. Government as to timely
payment of principal and interest and ARMS are guaranteed by the U.S.
Government, its agencies or instrumentalities (including government-sponsored
enterprises as noted above), the market value of these securities, upon which
the Funds' daily net asset value is based, will fluctuate. The Funds are subject
to interest-rate risk, that is, the risk that increases in interest rates may
adversely affect the

                                      22
<PAGE>
 
value of the securities in which the Funds invest, and hence the value of your
investment in the Funds. The value of the securities in which a Fund invests
generally changes inversely to changes in interest rates. However, the
adjustable-rate feature of the mortgages underlying the ARMS and the CMOs in
which the Income Fund may invest should reduce, but will not eliminate, price
fluctuations in such securities, particularly during periods of extreme
fluctuations in market interest rates.

     The full and timely payment of principal and interest on GNMA ARMS is
guaranteed by GNMA and backed by the full faith and credit of the U.S.
Government. FNMA also guarantees full and timely payment of both interest and
principal, while FHLMC guarantees full and timely payment of interest and
ultimate payment of principal. FNMA and FHLMC ARMS are not backed by the full
faith and credit of the U.S. Government. However, because FNMA and FHLMC are
government-sponsored enterprises, these securities are considered by some
investors to be high-quality investments that present minimal credit risks. The
yields provided by these ARMS have historically exceeded the yields on other
types of U.S. Government securities with comparable maturities. Of course, there
can be no assurance that this historical performance will continue or that
either Fund, which are diversified funds, will meet its investment objective.

     Moreover, no assurance can be given that the U.S. Government would supply
financial support to U.S. Government-sponsored enterprises such as FNMA and
FHLMC in the event of a default in payment on the underlying mortgages which the
government- sponsored enterprise is unable to make good. Principal on the
mortgages underlying the mortgage pass-through securities in which the Funds may
invest may be prepaid in advance of maturity. Such prepayments tend to increase
when interest rates decline and may present a Fund with more principal to invest
at lower rates. The converse also tends to be the case.

     S&P and Moody's assign ratings based upon their judgment of the risk of
default (i.e., the risk that the issuer or guarantor may default in the payment
of principal and/or interest) of the securities underlying the CMOs. However,
investors should understand that most of the risk of these securities comes from
interest-rate risk (i.e.,  the risk that market interest rates may adversely
affect the value of the securities in which a Fund invests) and not from the
risk of default. CMOs may have significantly greater interest rate risk than
traditional government securities with identical ratings. The adjustable-rate
portions of CMOs have significantly less interest rate risk.

     U.S. Government obligations have been selected by Wells Fargo Bank as the
Income Fund's principal investments because of their relatively low purchase and
sale transaction costs and because of the low default risk associated with them
(i.e.,  they are issued or guaranteed as to principal and interest by the U.S.
Government, its agencies or instrumentalities).

     The Funds may invest in illiquid securities which may include certain
restricted securities. Illiquid securities may be difficult to sell promptly at
an acceptable price. Certain restricted securities may be subject to legal
restrictions on resale. Delay or difficulty in selling securities may result in
a loss or be costly to a Fund.

     The adviser may use certain derivative investments or techniques, such as
investments in floating- and variable-rate instruments, structured notes and
certain U.S. Government obligations,

                                      23
<PAGE>
 
to adjust the risk and return characteristics of a Fund's portfolio. Derivatives
are financial instruments whose value is derived, at least in part, from the
price of another security or a specified asset, index or rate. Some derivatives
may be more sensitive than direct securities to changes in interest rates or
sudden market moves. Some derivatives also may be susceptible to fluctuations in
yield or value due to their structure or contract terms. If a Fund's adviser
judges market conditions incorrectly, the use of certain derivatives could
result in a loss, regardless of the adviser's intent in using the derivatives.

     The Intermediate Bond Fund may invest up to 25% of its assets in "Yankee
Bonds." Yankee Bonds are U.S. dollar-denominated debt obligations issued in the
U.S. by foreign banks and corporations. Such investments may involve special
risks and considerations not typically associated with investing in U.S.
companies. These include differences in accounting, auditing and financial
reporting standards; generally higher commission rates on foreign portfolio
transactions; the possibility of nationalization, expropriation or confiscatory
taxation; adverse changes in investment or exchange control regulations (which
may include suspension of the ability to transfer currency from a country); and
political instability which could affect U.S. investments in foreign countries.
Additionally, dispositions of foreign securities and dividends and interest
payable on those securities may be subject to foreign taxes, including
withholding taxes. Foreign securities often trade with less frequency and volume
than domestic securities and, therefore, may exhibit greater price volatility.
The Fund's investments may be affected either unfavorably or favorably by
fluctuations in the relative rates of exchange between the currencies of
different nations, by exchange control regulations and by indigenous economic
and political developments.

     There is, of course, no assurance that a Fund will achieve its investment
objective or be successful in preventing or minimizing the risk of loss that is
inherent in investing in particular types of investment products.

</TABLE>

     As of January 1, 1998, Peter G. Gordon will replace Robert M. Joses on the
Board of Directors of the Wells Fargo Fund Complex.

     Directors of the Company are compensated annually by the Company and by all
the registrants in each fund complex they serve as indicated above and also are
reimbursed for all out-of-pocket expenses relating to attendance at board
meetings.  The Company, Stagecoach Trust and Life & Annuity Trust are considered
to be members of the same fund complex as such term is defined in Form N-1A
under the 1940 Act (the "Wells Fargo Fund Complex").  Overland Express Funds,
Inc. and Master Investment Trust, two investment companies previously advised by
Wells Fargo Bank, were part of the Wells Fargo Fund Complex prior to December
15, 1997.  These companies are no longer part of the Wells Fargo Fund Complex.
MasterWorks Funds Inc., Master Investment Portfolio, and Managed Series
Investment Trust together form a separate fund complex (the "BGFA Fund
Complex").  Each of the Directors and Officers of the Company serves in the
identical capacity as directors and officers or as trustees and/or officers of
each registered open-end management investment company in both the Wells Fargo
and BGFA Fund Complexes, except for Joseph N. Hankin, who only serves the
aforementioned members of the Wells Fargo Fund Complex.  The Directors are
compensated by other companies and trusts within a fund complex for 

                                      26
<PAGE>
 
their services as directors/trustees to such companies and trusts. Currently the
Directors do not receive any retirement benefits or deferred compensation from
the Company or any other member of each fund complex.

     As of the date of this SAI, Directors and Officers of the Company as a
group beneficially owned less than 1% of the outstanding shares of the Company.

to receive a fee, payable monthly, at the annual rate of 0.15% of the average
daily net assets of the predecessor portfolio.

     For the year ended September 30, 1996, the Fund paid, after waivers,
$55,482 for administration services.  This amount reflects fees paid to
Stephens, as sole Administrator to the Fund, for the period begun September 6,
1996 and ended September 30, 1996.  During this time, Stephens was entitled to
receive a fee, payable monthly, at the annual rate of 0.05% of the

Intermediate Bond Fund's average daily net assets. The amount also reflects the
net administration fees paid by the predecessor portfolio to Furman Selz for the
period begun October 1, 1995 and ended September 5, 1996.

     Prior to October 1, 1995, ALPS Mutual Funds Service, Inc. ("ALPS") served
as the Administrator for the predecessor portfolio of the Intermediate Bond
Fund. For its administration services, ALPS was entitled to receive the dollar
amounts indicated below for the periods indicated below.  ALPs did not waive any
administration fees during this period.  In 1995, the Fund changed its fiscal
year-end from May 31 to September 30.

     SPONSOR AND DISTRIBUTOR.  Stephens (the "Distributor"), located at 111
Center Street, Little Rock, Arkansas 72201, serves as sponsor and distributor
for the Funds.

     SHAREHOLDER SERVICING AGENT.  The Funds have approved Servicing Plans and
have entered into related Shareholder Servicing Agreements, on behalf of the
Institutional Class shares, with financial institutions, including Wells Fargo
Bank.  Under the agreement, Shareholder Servicing Agents (including Wells Fargo
Bank) agree to perform, as agents for their customers, administrative services,
with respect to Fund shares, which include aggregating and transmitting
shareholder orders for purchases, exchanges and redemptions; maintaining
shareholder accounts and records; and providing such other related services as
the Company to a shareholder may reasonably request.  For providing shareholder
services, a Servicing Agent is entitled to a fee from the applicable Fund, not
to exceed 0.25%, on an annualized basis, of the average daily net assets of the
class of shares owned of record or beneficially by the customers of 

                                      31

the Servicing Agent during the period for which payment is being made. The
Servicing Plans and related forms of shareholder servicing agreements were
approved by the Company's Board of Directors and provide that a Fund shall not
be obligated to make any payments under such Plans or related Agreements that
exceed the maximum amounts payable under the Conduct Rules of the National
Association of Securities Dealers, Inc. ("NASD").

     For the period indicated below, the dollar amounts of shareholder servicing
fees paid, without waivers, by the Funds to Wells Fargo Bank or its affiliates
were as follows:

     For the period begun October 1, 1995 and ended September 5, 1996, and under
a similar service agreement, payments were made to First Interstate Bancorp for
the Funds.  For the period begun September 6, 1996 and ended September 30, 1996
shareholder servicing fees were paid to Wells Fargo Bank or its affiliates.  For
the year ended September 30, 1997, no shareholder servicing fees, after waivers,
were paid to Wells Fargo Bank or its affiliates.

     General.  Each Servicing Plan will continue in effect from year to year if
     -------                                                                   
such continuance is approved by a majority vote of the Directors of the Company,
including a majority of the Directors who are not "interested persons" (as
defined in the 1940 Act) of the Funds ("Non-Interested Directors").  Any form of
Servicing Agreement related to a Servicing Plan also must be approved by such
vote of the Directors and the Non-Interested Directors.  Servicing Agreements
may be terminated at any time, without payment of any penalty, by vote of a
majority of the Board of Directors, including a majority of the Non-Interested
Directors.  No material amendment to the Servicing Plans and related Servicing
Agreements may be made except by a majority of both the Directors of the Company
and the Non-Interested Directors.

     Each Servicing Plan requires that the Administrator shall provide to the
Directors, and the Directors shall review, at least quarterly, a written report
of the amounts expended (and purposes therefor) under the Servicing Plan.

     CUSTODIAN.  Wells Fargo Bank acts as Custodian for each Fund.  The
Custodian, among other things, maintains a custody account or accounts in the
name of each Fund, receives and delivers all assets for each Fund upon purchase
and upon sale or maturity, collects and receives all income and other payments
and distributions on account of the assets of each Fund, and pays all expenses
of each Fund.  For its services as Custodian, Wells Fargo Bank is entitled to
receive fees as follows:  a net asset charge at the annual rate of 0.0167%,
payable monthly, plus specified transaction charges.  Wells Fargo Bank also will
provide portfolio accounting services under the Custody Agreement as follows: a
monthly base fee of $2,000 plus a net asset fee at the annual

0.045% of the next $50,000,000, and 0.020% of the average daily net assets in
excess of $100,000,000.

the Intermediate Bond Fund predecessor portfolio. Pacifica compensated Furman
Selz for providing personnel and facilities to perform transfer agency related
services for Pacifica at a rate intended to represent the cost of providing such
services.

     Short-Intermediate U.S. Government Income and U.S. Government Income Funds.
     --------------------------------------------------------------------------
Under the prior transfer agency agreement for the Short-Intermediate U.S.
Government Income and U.S. Government Income Funds, Wells Fargo Bank was
entitled to receive a per account fee plus transaction fees and reimbursement of
out-of-pocket expenses, with a minimum of $3,000 per month per Fund, unless net
assets of the Fund were under $20 million. For as long as a Fund's assets
remained under $20 million, the Fund was not charged any transfer agency fees.

     UNDERWRITING COMMISSIONS.  The Institutional Class of each Fund does not
charge any front-end sales loads or contingent-deferred sales charges in
connection with the purchase and redemption of its shares, and therefore pays no
underwriting commissions to the Distributor.

                           PERFORMANCE CALCULATIONS

     The Funds may advertise certain yield and total return information.
Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown.  Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.

     In connection with communicating its performance to current or prospective
shareholders, these figures may also be compared to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

     Performance information for a Fund or Class of shares in a Fund may be
useful in reviewing the performance of such Fund or Class of shares and for
providing a basis for comparison with investment alternatives.  The yield of a
Fund and the yield of a Class of shares in a Fund, however, may not be
comparable to the yields from investment alternatives because of differences in
the foregoing variables and differences in the methods used to value portfolio
securities, compute expenses and calculate yield.

     TOTAL RETURN:  The Funds may advertise certain total return information
     ------------                                                           
computed in the manner described in the Prospectus.  As and to the extent
required by the SEC, an average annual compound rate of return ("T") is computed
by using the redeemable value at the end of a specified period ("ERV") of a
hypothetical initial investment ("P") over a period of years ("n") according to
the following formula:  P(1+T)n=ERV.  In addition, as indicated in each
Prospectus, each Fund also may, at times, calculate total return based on net
asset value per share (rather than the public offering price), in which case the
figures would not reflect the effect of any sales charges that would have been
paid by an investor, or based on the assumption that a sales charge 

                                      34
<PAGE>
 
other than the maximum sales charge (reflecting a Volume Discount) was assessed,
provided that total return data derived pursuant to the calculation described
above also are presented.

     Performance information may be advertised for non-standardized periods,
including year-to-date and other periods less than a year for the Funds.

     YIELD CALCULATIONS:  The Funds may, from time to time, include their
     ------------------                                                  
yields, tax-equivalent yields (if applicable) and effective yields in
advertisements or reports to shareholders or prospective investors.  Quotations
of yield for the Funds are based on the investment income per share earned
during a particular seven-day or thirty-day period, less expenses accrued during
a period ("net investment income") and are computed by dividing net investment
income by the offering price per share on the last date of the period, according
to the following formula:

                          YIELD - 2[(a - b + 1)/6/ -1]
                                     -----            

                                       Cd

     where a = dividends and interest earned during the period, b = expenses
accrued for the period (net of any reimbursements), c = the average daily number
of shares outstanding during the period that were entitled to receive dividends,
and d = the maximum offering price per share on the last day of the period.

     EFFECTIVE YIELD:  Effective yields for the Funds are based on the change in
     ---------------                                                            
the value of a hypothetical investment (exclusive of capital changes) over a
particular thirty-day period, less a pro-rata share of each Fund's expenses
accrued over that period (the "base period"), and stated as a percentage of the
investment at the start of the base period (the "base period return").  The base
period return is then annualized multiplying by 365/30, with the resulting yield
figure carried to at least the nearest hundredth of one percent.  "Effective
yield" for the Funds assumes that all dividends received during the period have
been reinvested.  Calculation of "effective yield" begins with the same "base
period return" used in the calculation of yield, which is then annualized to
reflect weekly compounding pursuant to the following formula:

        Effective Thirty-Day Yield = [(Base Period Return +1)365/30]-1.

     From time to time and only to the extent the comparison is appropriate for
a Fund or a Class of shares, the Company may quote the performance or price-
earning ratio of a Fund or Class in advertising and other types of literature as
compared to the performance of the S&P Index, the Dow Jones Industrial Average,
the Lehman Brothers 20+ Treasury Index, the Lehman Brothers 5-7 Year Treasury
Index, Donoghue's Money Fund Averages, Real Estate Investment Averages (as
reported by the National Association of Real Estate Investment Trusts), Gold
Investment Averages (provided by World Gold Council), Bank Averages (which are
calculated from figures supplied by the U.S. League of Savings Institutions
based on effective annual rates of interest on both passbook and certificate
accounts), average annualized certificate of deposit rates (from the Federal
Reserve G-13 Statistical Releases or the Bank Rate Monitor), the Salomon One
Year Treasury Benchmark Index, the Consumer Price Index (as published by the
U.S. Bureau of Labor Statistics), other managed or unmanaged indices or
performance data of bonds, municipal securities, stocks or government securities
(including data provided by Ibbotson Associates), or by other services,
companies, publications or persons who monitor mutual funds on overall
performance or other criteria.  The S&P Index and the Dow Jones Industrial
Average are unmanaged indices of selected common stock prices.  The performance
of the Funds or a Class also may be compared to that of other mutual funds
having similar objectives.  This comparative performance could be expressed as a
ranking prepared by Lipper Analytical Services, Inc., CDA Investment
Technologies, Inc., Bloomberg Financial Markets or Morningstar, Inc.,
independent services which monitor the performance of mutual funds.  The Funds'
performance will be calculated by relating net asset value per share at the
beginning of a stated period to the net asset value of the investment, assuming
reinvestment of all gains distributions and dividends paid, at the end of the
period.  The Funds' comparative performance will be based on a comparison of
yields, as described above, or total return, as reported by Lipper, Survey
Publications, Donoghue or Morningstar, Inc.

     Any such comparisons may be useful to investors who wish to compare past
performance of the Funds or a Class with that of competitors.  Of course, past
performance cannot be a guarantee of future results.  The Company also may
include, from time to time, a reference to certain marketing approaches of the
Distributor, including, for example, a reference to a potential shareholder
being contacted by a selected broker or dealer.  General mutual fund statistics
provided by the Investment Company Institute may also be used.

     The Company also may use the following information in advertisements and
other types of literature, only to the extent the information is appropriate for
the Fund:  (i) the Consumer Price Index may be used to assess the real rate of
return from an investment in a Fund; (ii) other government statistics,
including, but not limited to, The Survey of Current Business, may be used to
illustrate investment attributes of a Fund or the general economic, business,
investment, or financial environment in which a Fund operates; (iii) the effect
of tax-deferred compounding on the investment returns of a Fund, or on returns
in general, may be illustrated by graphs, charts, etc., where such graphs or
charts would compare, at various points in time, the return from an investment
in a Fund (or returns in general) on a tax-deferred basis (assuming reinvestment
of capital gains and dividends and assuming one or more tax rates) with the
return on a taxable basis; and (iv) the sectors or industries in which a Fund
invests may be compared to relevant 

                                      37
<PAGE>
 
indices of stocks or surveys (e.g., S&P Industry Surveys) to evaluate a Fund's
historical performance or current or potential value with respect to the
particular industry or sector.

     In addition, the Company also may use, in advertisements and other types of
literature, information and statements: (1) showing that bank savings accounts
offer a guaranteed return of principal and a fixed rate of interest, but no
opportunity for capital growth; and (2)  describing Wells Fargo Bank, and its
affiliates and predecessors, as one of the first investment managers to advise
investment accounts using asset allocation and index strategies.  The Company
also may include in advertising and other types of literature information and
other data from reports and studies prepared by the Tax Foundation, including
information regarding federal and state tax levels and the related "Tax Freedom
Day."

     The Company also may discuss in advertising and other types of literature
that a Fund has been assigned a rating by a nationally recognized statistical
rating organization ("NRSRO"), such as Standard & Poor's Corporation.  Such
rating would assess the creditworthiness of the investments held by the Fund.
The assigned rating would not be a recommendation to purchase, sell or hold the
Fund's shares since the rating would not comment on the market price of the
Fund's shares or the suitability of the Fund for a particular investor.  In
addition, the assigned rating would be subject to change, suspension or
withdrawal as a result of changes in, or unavailability of, information relating
to the Fund or its investments.  The Company may compare the Fund's performance
with other investments which are assigned ratings by NRSROs.  Any such
comparisons may be useful to investors who wish to compare the Fund's past
performance with other rated investments.

     From time to time, the Funds may use the following statements, or
variations thereof, in advertisements and other promotional materials:  "Wells
Fargo Bank, as a Shareholder Servicing Agent for the Stagecoach Funds, provides
various services to its customers that are also shareholders of the Funds.
These services may include access to Stagecoach Funds' account information
through Automated Teller Machines (ATMs), the placement of purchase and
redemption requests for shares of the Funds through ATMs and the availability of
combined Wells Fargo Bank and Stagecoach Funds account statements."

     The Company also may disclose, in advertising and other types of
literature, information and statements that Wells Fargo Investment Management
("WFIM"), a division of Wells Fargo Bank, is listed in the top 100 by
Institutional Investor magazine in its July 1996 survey "America's Top 300 Money
Managers."  This survey ranks money managers in several asset categories.  The
Company may also disclose in advertising and other types of sales literature the
assets and categories of assets under management by the Company's investment
adviser.  The Company may also disclose in advertising and other types of sales
literature the assets and categories of assets under management by a fund's
investment adviser or sub-adviser and the total amount of assets and mutual fund
assets managed by Wells Fargo Bank.  As of August 1, 1997, Wells Fargo Bank and
its affiliates provided investment Advisory services for approximately $57
billion of assets of individual, trusts, estates and institutions and $19
billion of mutual fund assets.

                                    38
<PAGE>
 
     The Company also may discuss in advertising and other types of literature
the features, terms and conditions of Wells Fargo Bank accounts through which
investments in the Funds may be made via a "sweep" arrangement, including,
without limitation, the Managed Sweep Account, Money Market Checking Account,
California Tax-Free Money Market Checking Account, Money Market Access Account
and California Tax-Free Money Market Access Account (collectively, the "Sweep
Accounts").  Such advertisements and other literature may include, without
limitation, discussions of such terms and conditions as the minimum deposit
required to open a Sweep Account, a description of the yield earned on shares of
the Funds through a Sweep Account, a description of any monthly or other service
charge on a Sweep Account and any minimum required balance to waive such service
charges, any overdraft protection plan offered in connection with a Sweep
Account, a description of any ATM or check privileges offered in connection with
a Sweep Account and any other terms, conditions, features or plans offered in
connection with a Sweep Account.  Such advertising or other literature may also
include a discussion of the advantages of establishing and maintaining a Sweep
Account, and may include statements from customers as to the reasons why such
customers have established and maintained a Sweep Account.

     The Company may disclose in advertising and other types of literature that
investors can open and maintain Sweep Accounts over the Internet or through
other electronic channels (collectively, "Electronic Channels").  Such
advertising and other literature may discuss the investment options available to
investors, including the types of accounts and any applicable fees.  Such
advertising and other literature may disclose that Wells Fargo Bank is the first
major bank to offer an on-line application for a mutual fund account that can be
filled out completely through Electronic Channels.  Advertising and other
literature may disclose that Wells Fargo Bank may maintain Web sites, pages or
other information sites accessible through Electronic Channels (an "Information
Site") and may describe the contents and features of the Information Site and
instruct investors on how to access the Information Site and open a Sweep
Account.  Advertising and other literature may also disclose the procedures
employed by Wells Fargo Bank to secure information provided by investors,
including disclosure and discussion of the tools and services for accessing
Electronic Channels.  Such advertising or other literature may include
discussions of the advantages of establishing and maintaining a Sweep Account
through Electronic Channels and testimonials from Wells Fargo Bank customers or
employees and may also include descriptions of locations where product
demonstrations may occur.  The Company may also disclose the ranking of Wells
Fargo Bank as one of the largest money managers in the United States.

                       DETERMINATION OF NET ASSET VALUE

     Net asset value per share for each class of the Funds are determined on
each day the Funds are open as of 1:00 p.m. (Pacific time).  Expenses and fees,
including advisory fees, are accrued daily and are taken into account for the
purpose of determining the net asset value of a Fund's shares.

                                      39
<PAGE>
 
     Securities of the Fund for which market quotations are available are valued
at latest prices.  Securities of the Fund for which the primary market is a
national securities exchange or the National Association of Securities Dealers
Automated Quotations National Market System are valued at last sale prices.  In
the absence of any sale of such securities on the valuation date and in the case
of other securities, including U.S. Government securities but excluding money
market instruments maturing in 60 days or less, the valuations are based on
latest quoted bid prices.   Money market instruments maturing in 60 days or less
are valued at amortized cost.  Futures contracts will be marked to market daily
at their respective settlement prices determined by the relevant exchange.
These prices are not necessarily final closing prices, but are intended to
represent prices prevailing during the final 30 seconds of the trading day.
Options listed on a national exchange are valued at the last sale price on the
exchange on which they are traded at the close of the NYSE, or, in the absence
of any sale on the valuation date, at latest quoted bid prices.  Options not
listed on a national exchange are valued at latest quoted bid prices.  Debt
securities maturing in 60 days or less are valued at amortized cost.  In all
cases, bid prices will be furnished by a reputable independent pricing service
approved by the Board of Directors.  Prices provided by an independent pricing
service may be determined without exclusive reliance on quoted prices and may
take into account appropriate factors such as institutional-size trading in
similar groups of securities, yield, quality, coupon rate, maturity, type of
issue, trading characteristics and other market data.  All other securities and
other assets of the Fund for which current market quotations are not readily
available are valued at fair value as determined in good faith by the Company's
Directors and in accordance with procedures adopted by the Directors.

                ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

     Shares may be purchased on any day the Fund is open for business. The Fund
is open for business each day the NYSE is open for trading (a "Business Day").
Currently, the NYSE is closed on New Year's Day, Martin Luther King, Jr. Day,
President's Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day and Christmas Day (each a "Holiday"). When any Holiday falls on
a weekend, the NYSE typically is closed on the weekday immediately before or
after such Holiday.

     Payment for shares may, in the discretion of the adviser, be made in the
form of securities that are permissible investments for the Fund as described in
the Prospectus. For further information about this form of payment please
contact Stephens. In connection with an in-kind securities payment, the Fund
will require, among other things, that the securities be valued on the day of
purchase in accordance with the pricing methods used by the Fund and that the
Fund receives satisfactory assurances that (i) it will have good and marketable
title to the securities received by it; (ii) that the securities are in proper
form for transfer to the Fund; and (iii) adequate information will be provided
concerning the basis and other matters relating to the securities.

     Under the 1940 Act, the Fund may suspend the right of redemption or
postpone the date of payment upon redemption for any period during which the
NYSE is closed (other than customary weekend and holiday closings, or during
which trading is restricted, or during which as determined by the SEC by rule or
regulation) an emergency exists as a result of which disposal or valuation of

                                      40
<PAGE>
 
portfolio securities is not reasonably practicable, or for such periods as the
SEC may permit.  The Company may also redeem shares involuntarily or make
payment for redemption in securities or other property if it appears appropriate
to do so in light of the Company's responsibilities under the 1940 Act.

     In addition, the Company may redeem shares involuntarily to reimburse the
Fund for any losses sustained by reason of the failure of a shareholder to make
full payment for shares purchased or to collect any charge relating to a
transaction effected for the benefit of a shareholder which is applicable to
shares of the Fund as provided from time to time in the Prospectus.

                            PORTFOLIO TRANSACTIONS

     The Company has no obligation to deal with any dealer or group of dealers
in the execution of transactions in portfolio securities. Subject to policies
established by the Company's Board of Directors, Wells Fargo Bank is responsible
for the Fund's investment decisions and the placing of portfolio transactions.
In placing orders, it is the policy of the Company to obtain the best overall
terms taking into account the dealer's general execution and operational
facilities, the type of transaction involved and other factors such as the
dealer's risk in positioning the securities involved.  While Wells Fargo Bank
generally seeks reasonably competitive spreads or commissions, a Fund will not
necessarily be paying the lowest spread or commission available.

     Purchase and sale orders of the securities held by the Funds may be
combined with those of other accounts that Wells Fargo Bank manages, and for
which it has brokerage placement authority, in the interest of seeking the most
favorable overall net results. When Wells Fargo Bank determines that a
particular security should be bought or sold for a Fund and other accounts
managed by Wells Fargo Bank, Wells Fargo Bank undertakes to allocate those
transactions among the participants equitably.

     Purchases and sales of securities usually will be principal transactions.
Portfolio securities normally will be purchased or sold from or to dealers
serving as market makers for the securities at a net price.  The Fund also will
purchase portfolio securities in underwritten offerings and may purchase
securities directly from the issuer.  Generally, money market securities, ARMS
and CMOs are traded on a net basis and do not involve brokerage commissions.
The cost of executing the Fund's portfolio securities transactions will consist
primarily of dealer spreads and underwriting commissions.  Under the 1940 Act,
persons affiliated with the Company are prohibited from dealing with the Company
as a principal in the purchase and sale of securities unless an exemptive order
allowing such transactions is obtained from the SEC or an exemption is otherwise
available.

     THE U.S. GOVERNMENT INCOME AND SHORT-INTERMEDIATE U.S. GOVERNMENT INCOME
FUNDS MAY PURCHASE MUNICIPAL OBLIGATIONS FROM UNDERWRITING SYNDICATES OF WHICH
STEPHENS, WELLS FARGO BANK OR THEIR AFFILIATES IS A MEMBER UNDER CERTAIN
CONDITIONS IN ACCORDANCE WITH PROVISIONS OF A RULE ADOPTED UNDER THE 1940 ACT
AND IN COMPLIANCE WITH PROCEDURES ADOPTED BY THE BOARD OF DIRECTORS.

                                      41
                                
<PAGE>
 
     In assessing the best overall terms available for any transaction, Wells
Fargo Bank considers factors deemed relevant, including the breadth of the
market in the security, the price of the security, the financial condition and
execution capability of the broker or dealer, and the reasonableness of the
commission, if any, both for the specific transaction and on a continuing basis.
Wells Fargo Bank may cause the Fund to pay a broker/dealer which furnishes
brokerage and research services a higher commission than that which might be
charged by another broker/dealer for effecting the same transaction, provided
that Wells Fargo Bank determines in good faith that such commission is
reasonable in relation to the value of the brokerage and research services
provided by such broker/dealer, viewed in terms of either the particular
transaction or the overall responsibilities of Wells Fargo Bank. Such brokerage
and research services might consist of reports and statistics relating to
specific companies or industries, general summaries of groups of stocks or bonds
and their comparative earnings and yields, or broad overviews of the stock,
bond, and government securities markets and the economy.

     Supplementary research information so received is in addition to, and not
in lieu of, services required to be performed by Wells Fargo Bank and does not
reduce the advisory fees payable by the Fund. The Board of Directors will
periodically review the commissions paid by the Fund to consider whether the
commissions paid over representative periods of time appear to be reasonable in
relation to the benefits inuring to the Fund. It is possible that certain of the
supplementary research or other services received will primarily benefit one or
more other investment companies or other accounts for which Wells Fargo Bank
exercises investment discretion. Conversely, the Fund may be the primary
beneficiary of the research or services received as a result of portfolio
transactions effected for such other account or investment company.

     Under Section 28(e) of the Securities Exchange Act of 1934, an adviser
shall not be "deemed to have acted unlawfully or to have breached its fiduciary
duty" solely because under certain circumstances it has caused the account to
pay a higher commission than the lowest available. To obtain the benefit of
Section 28(e), an adviser must make a good faith determination that the
commissions paid are "reasonable in relation to the value of the brokerage and
research services provided . . . viewed in terms of either that particular
transaction or its overall responsibilities with respect to the accounts as to
which it exercises investment discretion and that the services provided by a
broker provide an adviser with lawful and appropriate assistance in the
performance of its investment decision-making responsibilities." Accordingly,
the price to the Fund in any transaction may be less favorable than that
available from another broker/dealer if the difference is reasonably justified
by other aspects of the portfolio execution services offered.

     Broker/dealers utilized by Wells Fargo Bank may furnish statistical,
research and other information or services which are deemed by Wells Fargo Bank
to be beneficial to the Fund's investment program. Research services received
from brokers supplement Wells Fargo Bank's own research and may include the
following types of information: statistical and background information on
industry groups and individual companies; forecasts and interpretations with
respect to U.S. and foreign economies, securities, markets, specific industry
groups and individual companies; information on political developments;
portfolio management strategies; performance information on securities and
information concerning prices of securities; and information supplied 

                                      42
<PAGE>
 
by specialized services to Wells Fargo Bank and to the Company's Directors with
respect to the performance, investment activities and fees and expenses of other
mutual Funds. Such information may be communicated electronically, orally or in
written form. Research services may also include the providing of equipment used
to communicate research information, the arranging of meetings with management
of companies and the providing of access to consultants who supply research
information.

     The outside research assistance is useful to Wells Fargo Bank since the
brokers utilized by Wells Fargo Bank as a group tend to follow a broader
universe of securities and other matters than the staff of Wells Fargo Bank can
follow. In addition, this research provides Wells Fargo Bank with a diverse
perspective on financial markets. Research services which are provided to Wells
Fargo Bank by brokers are available for the benefit of all accounts managed or
advised by Wells Fargo Bank. It is the opinion of Wells Fargo Bank that this
material is beneficial in supplementing their research and analysis; and,
therefore, it may benefit the Fund by improving the quality of Wells Fargo
Bank's investment advice.  The advisory fees paid by the Funds are not reduced
because Wells Fargo Bank receives such services.

     BROKERAGE COMMISSIONS.  During the fiscal periods ended September 30, 1996,
September 30, 1995, May 31, 1995 and May 31, 1994, the predecessor portfolio of
the Intermediate Bond Fund did not pay any brokerage commissions, because all of
their portfolio transactions occurred in the over-the-counter market.

     For the years ended December 31, 1994 and 1995, and the period ended
September 30, 1996, the Short-Intermediate U.S. Government Income and U.S.
Government Income and U.S. Government Income Funds did not pay any brokerage
commissions.

     SECURITIES OF REGULAR BROKER/DEALERS. As of March 31, 1997, each Fund owned
securities (pooled repurchase agreements) of its "regular brokers or dealers" as
defined in the 1940 Act or their parents, as follows:

U.S. Government Income         Goldman Sachs & Co.               $    839,000                   
</TABLE>
 
     PORTFOLIO TURNOVER.  The portfolio turnover rate is not a limiting factor
when Wells Fargo Bank deems portfolio changes appropriate.

     Changes may be made in the portfolios consistent with the investment
objectives and policies of the Funds whenever such changes are believed to be in
the best interests of the Funds and their shareholders. The portfolio turnover
rate is calculated by dividing the lesser of purchases or sales of portfolio
securities by the average monthly value of the Fund's portfolio securities. For

                                      43
<PAGE>
 
purposes of this calculation, portfolio securities exclude all securities having
a maturity when purchased of one year or less.  Portfolio turnover generally
involves some expenses to the Funds, including brokerage commissions or dealer
mark-ups and other transaction costs on the sale of securities and the
reinvestment in other securities.  Portfolio turnover also can generate short-
term capital gain tax consequences.  Portfolio turnover rate is not a limiting
factor when Wells Fargo Bank deems portfolio changes appropriate.  The Short-
Intermediate U.S. Government Income portfolio turnover rate is generally not
expected to exceed 100%.

     The higher portfolio turnover rates for the U.S. Government Income Fund
should not adversely affect it because portfolio transactions ordinarily are
made directly with principals on a net basis and, consequently, the Fund usually
does not incur brokerage expenses.

                                 FUND EXPENSES

     From time to time, Wells Fargo Bank and Stephens may waive fees from the
Fund in whole or in part.  Any such waiver will reduce expenses and,
accordingly, have a favorable impact on the Fund's performance. Except for the
expenses borne by Wells Fargo Bank and Stephens, the Fund bears all costs of its
operations, including the compensation of its Directors who are not affiliated
with Stephens or Wells Fargo Bank or any of their affiliates; advisory,
shareholder servicing and administration fees; payments pursuant to any Plan;
interest charges; taxes; fees and expenses of its independent accountants, legal
counsel, transfer agent and dividend disbursing agent; expenses of redeeming
shares; expenses of preparing and printing Prospectuses (except the expense of
printing and mailing Prospectuses used for promotional purposes, unless
otherwise payable pursuant to a Plan), shareholders' reports, notices, proxy
statements and reports to regulatory agencies; insurance premiums and certain
expenses relating to insurance coverage; trade association membership dues;
brokerage and other expenses connected with the execution of portfolio
transactions; fees and expenses of its custodian, including those for keeping
books and accounts and calculating the NAV per share of the Fund; expenses of
shareholders' meetings; expenses relating to the issuance, registration and
qualification of the Fund's shares; pricing services, organizational expenses
and any extraordinary expenses. Expenses attributable to the Fund are charged
against Fund assets. General expenses of the Company are allocated among all of
the funds of the Company, including the Fund, in a manner proportionate to the
net assets of the Fund, on a transactional basis, or on such other basis as the
Company's Board of Directors deems equitable.

                             FEDERAL INCOME TAXES

     The following information supplements and should be read in conjunction
with the Prospectus section entitled "Taxes." The Prospectus describes generally
the tax treatment of distributions by the Fund. This section of the SAI includes
additional information concerning federal income taxes.

     In General.  The Company intends to qualify the Fund as a regulated
     ----------                                                         
investment company under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code") as long as such qualification is in the best interest of
the Fund's shareholders. The Fund will be treated as a 

                                      44
<PAGE>
 
separate entity for tax purposes and thus the provisions of the Code applicable
to regulated investment companies will generally be applied to the Fund, rather
than to the Company as a whole. In addition, net capital gains, net investment
income, and operating expenses will be determined separately for the Fund.

     Qualification as a regulated investment company under the Code requires,
among other things, that (a) the Fund derive at least 90% of its annual gross
income from dividends, interest, certain payments with respect to securities
loans, gains from the sale or other disposition of stock or securities or
foreign currencies (to the extent such currency gains are directly related to
the regulated investment company's principal business of investing in stock or
securities) and other income (including but not limited to gains from options,
futures or forward contracts) derived with respect to its business of investing
in such stock, securities or currencies; and (b) the Fund diversify its holdings
so that, at the end of each quarter of the taxable year, (i) at least 50% of the
market value of the Fund's assets is represented by cash, government securities
and other securities limited in respect of any one issuer to an amount not
greater than 5% of the Fund's 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
obligations and the securities of other regulated investment companies), or in
two or more issuers which the Fund controls and which are determined to be
engaged in the same or similar trades or businesses.

     In addition, the Fund must, in general, derive less than 30% of its gross
income from the sale or other disposition of securities or options thereon held
for less than three months.  However, this restriction has been repealed with
respect to taxable years beginning after August 5, 1997.

     The Fund must also distribute or be deemed to distribute to its
shareholders at least 90% of its net investment income earned in each taxable
year.  In general, these distributions must actually or be deemed to be made in
the taxable year.  However, in certain circumstances, such distributions may be
made in the 12 months following the taxable year.  The Fund intends to pay out
substantially all of its net investment income and net realized capital gains
(if any) for each year.

     Income and dividends received by the [Short-Intermediate & Government
Income] Funds from sources within foreign countries may be subject to
withholding and other taxes imposed by such countries.  Tax conventions between
certain countries and the United States may reduce or eliminate such taxes.
Although in some circumstances a regulated investment company can elect to "pass
through" foreign tax credits to its shareholders, the Fund does not expect to be
eligible to make such an election.

     Excise Tax.  A 4% nondeductible excise tax will be imposed on the Fund
     ----------                                                            
(other than to the extent of its tax-exempt interest income) to the extent it
does not meet certain minimum distribution requirements by the end of each
calendar year.  The Fund intends to actually or be deemed to distribute
substantially all of its net investment income and net capital gains by the end
of each calendar year and, thus, expects not to be subject to the excise tax.

                                      45

     Corporate shareholders of the Short-Term Government-Corporate Income Fund
may be eligible for the dividends-received deduction on dividends distributed
out of the Fund's net investment income attributable to dividends received from
domestic corporations, which, if received directly by the corporate shareholder,
would qualify for such deduction.  In order to qualify for the dividends-
received deduction, a corporate shareholder must hold the Fund shares paying the
dividends upon which the deduction is based for at least 46 days.

     Taxation of Fund Investments.  Except as provided herein, gains and losses
     ----------------------------                                              
on the sale of portfolio securities by the Fund will generally be capital gains
and losses.  Such gains and losses will ordinarily be long-term capital gain and
loss if the securities have been held by the Fund for more than 12 months at the
time of disposition of the securities (however, see "Capital Gain Distributions"
below).

     Gains recognized on the disposition of a debt obligation (including tax-
exempt obligations purchased after April 30, 1993) purchased by the Fund at a
market discount (generally at a price less than its principal amount) will be
treated as ordinary income to the extent of the portion of market discount which
accrued, but was not previously recognized pursuant to an available election,
during the term the Fund held the debt obligation.

     Capital Gain Distributions.  Distributions which are designated by the Fund
     --------------------------                                                 
as capital gain distributions will be taxed to shareholders as net capital gain
(generally, the excess of net long-term capital gain over net short-term capital
loss), to the extent such distributions are attributable to net capital gain of
the Fund, regardless of how long a shareholder has held Fund shares.  Such
distributions will be designated as capital gain distributions in a written
notice mailed by the Fund to the shareholders not later than 60 days after the
close of the Fund's taxable year.

     The Taxpayer Relief Act of 1997 (the "1997 Act") created several new
categories of capital gains applicable to noncorporate taxpayers.  Under prior
law, noncorporate taxpayers were generally taxed at a maximum rate of 28% on net
capital gain.  Noncorporate taxpayers are now generally taxed at a maximum rate
of 20% on net capital gain attributable to gains realized on the sale of
property held for greater than 18 months, and a maximum rate of 28% on net
capital gain attributable to gain realized on the sale of property held for
greater than 1 year and 18 months or less.  The 1997 Act retains the treatment
of short-term capital gain and did not affect the taxation of corporate
taxpayers.  The Treasury is authorized to issue regulations for application of
the reduced capital gain tax rates enacted under the 1997 Act to pass-through
entities, including regulated investment companies.  Noncorporate shareholders
of the Fund may therefore qualify for the reduced rate of tax on capital gain
dividends paid by the Fund.

     Other Distributions.  Although dividends will be declared daily based on
     -------------------                                                     
the Fund's daily earnings, for federal income tax purposes, the Fund's earnings
and profits will be determined at the end of each taxable year and will be
allocated pro rata over the entire year. For federal income tax purposes, only
amounts paid out of earnings and profits will qualify as dividends. Thus, if
during a taxable year the Fund's declared dividends (as declared daily
throughout the year) exceed the Fund's net income (as determined at the end of
the year), only that portion of the year's 

                                      46
<PAGE>
 
distributions which equals the year's earnings and profits will be deemed to
have constituted a dividend. It is expected that the Fund's net income, on an
annual basis, will equal the dividends declared during the year.

     Disposition of Fund Shares.  A disposition of Fund shares pursuant to
     ---------------------------                                          
redemption (including a redemption in-kind) or exchanges will ordinarily result
in a taxable capital gain or loss, depending on the amount received for the
shares (or are deemed to receive in the case of an exchange) and the cost of
your shares.

     If a shareholder exchanges or otherwise disposes of Fund shares within 90
days of having acquired such shares and if, as a result of having acquired those
shares, the shareholder subsequently pays a reduced sales charge or load on a
new purchase of shares of the Fund or a different regulated investment company,
the sales charge or load previously incurred acquiring the Fund's shares shall
not be taken into account (to the extent such previous sales charge or load does
not exceed the reduction in sales charge or load on the new purchase) for the
purpose of determining the amount of gain or loss on the disposition, but will
be treated as having been incurred in the acquisition of such other shares.
Also, any loss realized on a redemption or exchange of shares of the Fund will
be disallowed to the extent that substantially identical shares are acquired
within the 61-day period beginning 30 days before and ending 30 days after the
shares are disposed of.

     In addition, if a shareholder receives a designated capital gain
distribution (to be treated by the shareholder as a long-term capital gain) with
respect to any Fund share and such Fund share is held for six months or less,
then (unless otherwise disallowed) any loss on the sale or exchange of that Fund
share will be treated as a long-term capital loss to the extent of the
designated capital gain distribution.  The foregoing recharacterization rule
does not apply to losses realized under a periodic redemption plan.

     Federal Income Tax Rates.  As of the printing of this SAI, the maximum
     ------------------------                                              
individual tax rate applicable to ordinary income is 39.6% (marginal tax rates
may be higher for some individuals to reduce or eliminate the benefit of
exemptions and deductions); the maximum individual marginal tax rate applicable
to net capital gains is 28% (however, see "Capital Gain Distributions" above);
and the maximum corporate tax rate applicable to ordinary income and net capital
gains is 35% (marginal tax rates may be higher for some corporations to reduce
or eliminate the benefit of lower marginal income tax rates).  Naturally, the
amount of tax payable by an individual or corporation will be affected by a
combination of tax laws covering, for example, deductions, credits, deferrals,
exemptions, sources of income and other matters.

     If a Fund purchases shares in a "passive foreign investment company"
("PFIC"), the Fund may be subject to federal income tax and an interest charge
imposed by the IRS upon certain distributions from the PFIC or the Fund's
disposition of PFIC shares.  If a Fund invests in a PFIC, the Fund intends to
make an available election to mark-to-market its interest in PFIC shares.  Under
the election, the Fund will be treated as recognizing at the end of each taxable
year the excess, if any, of the fair market value of its interest in PFIC shares
over its basis in such shares.  Although such excess will be taxable to the Fund
as ordinary income notwithstanding 

                                      47
<PAGE>
 
any distributions by the PFIC, the Fund will not be subject to federal income
tax or the interest charge with respect to its interest in the PFIC.

     Foreign Shareholders.  Under the Code, distributions of net investment
     --------------------                                                  
income by the Fund to a nonresident alien individual, foreign trust (i.e., trust
which a U.S. court is able to exercise primary supervision over administration
of that trust and one or more U.S. persons have authority to control substantial
decisions of that trust), foreign estate (i.e., the income of which is not
subject to U.S. tax regardless of source), foreign corporation, or foreign
partnership (a "foreign shareholder") will be subject to U.S. withholding tax
(at a rate of 30% or a lower treaty rate). Withholding will not apply if a
dividend paid by the Fund to a foreign shareholder is "effectively connected"
with a U.S. trade or business, in which case the reporting and withholding
requirements applicable to U.S. citizens, U.S. residents or domestic
corporations will apply. Such tax withheld is generally not refundable.
Further, distributions of net long-term capital gains generally are not subject
to tax withholding.

     Backup Withholding.  The Company may be required to withhold, subject to
     ------------------                                                      
certain exemptions, at a rate of 31% ("backup withholding") on dividends,
capital gain distributions, and redemption proceeds (including proceeds from
exchanges) paid or credited to an individual Fund shareholder, unless a
shareholder certifies that the Taxpayer Identification Number ("TIN") provided
is correct and that the shareholder is not subject to backup withholding, or the
IRS notifies the Company that the shareholder's TIN is incorrect or the
shareholder is subject to backup withholding. Such tax withheld does not
constitute any additional tax imposed on the shareholder, and may be claimed as
a tax payment on the shareholder's federal income tax return. An investor must
provide a valid TIN upon opening or reopening an account. Failure to furnish a
valid TIN to the Company could subject the investor to penalties imposed by the
IRS.

     Other Matters.  Investors should be aware that the investments to be made
     -------------                                                            
by the Fund may involve sophisticated tax rules that may result in income or
gain recognition by the Fund without corresponding current cash receipts.
Although the Fund will seek to avoid significant noncash income, such noncash
income could be recognized by the Fund, in which case the Fund may distribute
cash derived from other sources in order to meet the minimum distribution
requirements described above.

     The foregoing discussion and the discussions in the Prospectus address only
some of the federal tax considerations generally affecting investments in the
Fund. Each investor is urged to consult his or her tax advisor regarding
specific questions as to federal, state or local taxes and foreign taxes.

                                 CAPITAL STOCK

     The Funds are three of the funds in the Stagecoach Family of Funds. The
Company was organized as a Maryland corporation on September 9, 1991 and
currently offers shares of over thirty funds.

                                      48
<PAGE>
 
     Most of the Company's funds are authorized to issue multiple classes of
shares, one class generally subject to a front-end sales charge and, in some
cases, one or more classes subject to a contingent-deferred sales charge, that
are offered to retail investors.  Certain of the Company's funds also are
authorized to issue other classes of shares, which are sold primarily to
institutional investors.  Each class of shares in a fund represents an equal,
proportionate interest in a fund with other shares of the same class.
Shareholders of each class bear their pro rata portion of the fund's operating
expenses, except for certain class-specific expenses (e.g., any state securities
registration fees, shareholder servicing fees or distribution fees that may be
paid under Rule 12b-1) that are allocated to a particular class.  Please contact
Stagecoach Shareholder Services at 1-800-222-8222 if you would like additional
information about other funds or classes of shares offered.

     With respect to matters affecting one class but not another, shareholders
vote as a class; for example, the approval of a Plan.  Subject to the foregoing,
all shares of the Fund have equal voting rights and will be voted in the
aggregate, and not by series, except where voting by a series is required by law
or where the matter involved only affects one series.  For example, a change in
a fund's fundamental investment policy affects only one series and would be
voted upon only by shareholders of the fund involved.  Additionally, approval of
an advisory contract, since it affects only one fund, is a matter to be
determined separately by series.  Approval by the shareholders of one series is
effective as to that series whether or not sufficient votes are received from
the shareholders of the other series to approve the proposal as to those series.

     As used in the Prospectus and in this SAI, the term "majority," when
referring to approvals to be obtained from shareholders of a class of shares of
the Fund, means the vote of the lesser of (i) 67% of the shares of the class
represented at a meeting if the holders of more than 50% of the outstanding
shares of the class are present in person or by proxy, or (ii) more than 50% of
the outstanding shares of the class of the Fund.  The term "majority," when
referring to approvals to be obtained from shareholders of the Fund, means the
vote of the lesser of (i) 67% of the shares of the Fund represented at a meeting
if the holders of more than 50% of the outstanding shares of the Fund are
present in person or by proxy, or (ii) more than 50% of the outstanding shares
of the Fund.  The term "majority," when referring to the approvals to be
obtained from shareholders of the Company as a whole, means the vote of the
lesser of (i) 67% of the Company's shares represented at a meeting if the
holders of more than 50% of the Company's outstanding shares are present in
person or by proxy, or (ii) more than 50% of the Company's outstanding shares.

     Shareholders are not entitled to any preemptive rights. All shares, when
issued, will be fully paid and non-assessable by the Company.  The Company may
dispense with an annual meeting of shareholders in any year in which it is not
required to elect Directors under the 1940 Act.

     Each share of a class of the Fund represents an equal proportional interest
in the Fund with each other share of the same class and is entitled to such
dividends and distributions out of the income earned on the assets belonging to
the Fund as are declared in the discretion of the Directors. In the event of the
liquidation or dissolution of the Company, shareholders of the Fund are entitled
to receive the assets attributable to that Fund that are available for
distribution, and a distribution of 

                                      49
<PAGE>
 
any general assets not attributable to a particular Fund or portfolio that are
available for distribution in such manner and on such basis as the Directors in
their sole discretion may determine.

     Set forth below, as of October 31, 1997, is the name, address and share
ownership of each person known by the Company to have beneficial or record
ownership of 5% or more of a class of a Fund or 5% or more of the voting
securities as a whole.

                                 SAI APPENDIX

     The following is a description of the ratings given by Moody's and S&P to
corporate and municipal bonds, municipal notes, and corporate and municipal
commercial paper.

     Corporate Bonds

     Moody's: The four highest ratings for corporate bonds are "Aaa," "Aa," "A"
and "Baa." Bonds rated "Aaa" are judged to be of the "best quality" and carry
the smallest amount of investment risk. Bonds rated "Aa" are of "high quality by
all standards," but margins of protection or other elements make long-term risks
appear somewhat greater than "Aaa" rated bonds. Bonds rated "A" possess many
favorable investment attributes and are considered to be upper medium grade
obligations. Bonds rated "Baa" are considered to be medium grade obligations;
interest payments and principal security appear adequate for the present, but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well. Moody's
also applies numerical modifiers in its rating system: 1, 2 and 3 in each rating
category from "Aa" through "Baa" in its rating system. The modifier 1 indicates
that the security ranks in the higher end of its category; the modifier 2
indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks
in the lower end.

     S&P: The four highest ratings for corporate and municipal bonds are "AAA,"
"AA," "A" and "BBB." Bonds rated "AAA" have the "highest rating" assigned by S&P
and have "an extremely strong capacity" to pay interest and repay principal.
Bonds rated "AA" have a "very strong capacity" to pay interest and repay
principal and "differ from the highest rated obligations only in small degree."
Bonds rated "A" have a "strong capacity" to pay interest and repay principal,
but are "somewhat more susceptible" to adverse effects of changes in economic
conditions or other circumstances than bonds in higher rated categories. Bonds
rated "BBB" are regarded as having "adequate protection parameters" to pay
interest and repay principal, but changes in economic conditions or other
circumstances are more likely to lead to a "weakened capacity" to make such
repayments. The ratings from "AA" to "BBB" may be modified by the addition of a
plus or minus sign to show relative standing within the category.

     Commercial Paper

     Moody's: The highest rating for commercial paper is "P-1" (Prime-1).
Issuers rated "P-1" have a "superior ability for repayment of senior short-term
debt obligations." Issuers rated "P-2" (Prime-2) "have a strong capacity for
repayment of senior short-term debt obligations," but earnings trends, while
sound, will be subject to more variation.

                                      A-1
<PAGE>
 
     S&P: The "A-1" rating for commercial paper is rated "in the highest
category" by S&P and "the obligor's capacity to meet its financial commitment on
the obligation is strong." The "A-1+" rating indicates that said capacity is
"extremely strong." The A-2 rating indicates that said capacity is
"satisfactory," but that corporate and municipal commercial paper rated "A-2" is
"more susceptible" to the adverse effects of changes in economic conditions or
other circumstances than commercial paper rated in higher rating categories.

                                    GENERAL

     The Money Market Mutual Fund was originally organized as a fund of the
Company.  The Fund commenced operations on July 1, 1992.

     The National Tax-Free Money Market Mutual Fund was originally organized as
a fund of the Company.  The Fund commenced operations on April 2, 1996.

     The Prime Money Market Mutual Fund operated as Pacific American Liquid
Assets, Inc. from commencement of operations on April 30, 1981, until it was
reorganized as a portfolio of Pacific American Fund on October 1, 1985.  On
October 1, 1994, the Fund was reorganized as the Pacific American Money Market
Portfolio of Pacifica Funds Trust ("Pacifica"); and in July 1995, it was renamed
the Pacifica Prime Money Market Fund.

     Prior to August 1, 1990, the Treasury Money Market Mutual Fund was known as
the Short-Term Government Fund.  The Treasury Money Market Mutual Fund operated
as a portfolio of Pacific American Fund through October 1, 1994, when it was
reorganized as the Pacific American U.S. Treasury Portfolio, a portfolio of
Pacifica Funds Trust.  In July 1995, the Fund was renamed the Pacifica Treasury
Money Market Fund.

     On September 6, 1996, the Pacifica Prime Money Market Fund and Pacifica
Treasury Money Market Fund were reorganized as the Company's Prime Money Market
Mutual Fund and Treasury Money Market Mutual Fund, respectively.

                            INVESTMENT RESTRICTIONS

     Fundamental Investment Policies
     -------------------------------

     Each Fund has adopted the following investment restrictions, all of which
are fundamental policies; that is, they may not be changed without approval by
the vote of the holders of a majority (defined in the Investment Company Act of
1940, as amended (the "1940 Act")) of the outstanding voting securities of such
Fund.

The Money Market Mutual Fund may not:

     (1)  purchase the securities of issuers conducting their principal business
activity in the same industry if, immediately after the purchase and as a result
thereof, the value of the Fund's investments in that industry would be 25% or
more of the current value of the Fund's total assets, provided that there is no
limitation with respect to investments in (i) the obligations of the United
States Government, its agencies or instrumentalities, and (ii) the obligations
of domestic banks (for the purpose of this restriction, domestic bank
obligations do not include obligations of U.S. branches of foreign banks or
obligations of foreign branches of U.S. banks);

     (2)  purchase or sell real estate or real estate limited partnerships
(other than money market securities or other securities secured by real estate
or interests therein or securities issued 

                                       1
<PAGE>
 
by companies that invest in real estate or interests therein), commodities or
commodity contracts (including futures contracts);

     (3)  purchase securities on margin (except for short-term credits necessary
for the clearance of transactions) or make short sales of securities;

     (4)  underwrite securities of other issuers, except to the extent that the
purchase of municipal securities or other permitted investments directly from
the issuer thereof or from an underwriter for an issuer and the later
disposition of such securities in accordance with the Fund's investment program
may be deemed to be an underwriting;

     (5)  make investments for the purpose of exercising control or management;

     (6)  issue senior securities, except that each Fund may borrow from banks
up to 10% of the current value of its net assets for temporary purposes only in
order to meet redemptions, and these borrowings may be secured by the pledge of
up to 10% of the current value of its net assets (but investments may not be
purchased while any such outstanding borrowings exceed 5% of its net assets);

     (7)  write, purchase or sell puts, calls, options, warrants or any
combination thereof, except that the Funds may purchase securities with put
rights in order to maintain liquidity; nor

     In addition, the Fund may not make loans of portfolio securities or other
assets, except that loans for purposes of this restriction will not include the
purchase of fixed time deposits, repurchase agreements, commercial paper and
other short-term obligations, and other types of debt instruments commonly sold
in public or private offerings.

The National Tax-Free Money Market Mutual Fund may not:

     (1)  purchase the securities of issuers conducting their principal business
activity in the same industry if, immediately after the purchase and as a result
thereof, the value of the Fund's investments in that industry would be 25% or
more of the current value of the Fund's total assets, provided that there is no
limitation with respect to investments in (i) municipal securities (for the
purpose of this restriction, private activity bonds and notes shall not be
deemed municipal securities if the payment of principal and interest on such
bonds or notes is the ultimate responsibility of non-governmental entities);
(ii) obligations of the U.S. Government, its agencies or instrumentalities
(including government-sponsored enterprises); and (iii) the obligations of
domestic banks (for the purpose of this restriction, domestic bank obligations
do not include obligations of U.S. branches of foreign banks or obligations of
foreign branches of U.S. banks);

     (2)  purchase or sell real estate or real estate limited partnerships
(other than municipal obligations or other securities secured by real estate or
interests therein or securities issued by companies that invest in real estate
or interests therein), commodities or commodity contracts (including futures
contracts) except that the Fund may purchase securities of an issuer which
invests or deals in commodities and commodity contracts and except that the Fund
may enter into futures and options contracts in accordance with its investment
policies;

                                       2
<PAGE>
 
     (3)  purchase securities on margin (except for short-term credits necessary
for the clearance of transactions), or make short sales of securities;

     (4)  underwrite securities of other issuers, except to the extent that the
purchase of municipal securities or other permitted investments directly from
the issuer thereof or from an underwriter for an issuer and the later
disposition of such securities in accordance with the Fund's investment program
may be deemed to be an underwriting;

     (5)  make investments for the purpose of exercising control or management;

     (6)  issue senior securities, except that the Fund may borrow from banks up
to 10% of the current value of its net assets for temporary purposes only in
order to meet redemptions, and these borrowings may be secured by the pledge of
up to 10% of the current value of its net assets (but investments may not be
purchased while any such outstanding borrowing in excess of 5% of its net assets
exists);

     (7)  write, purchase or sell puts, calls, warrants, options or any
combination thereof, except that the Fund may purchase securities with put
rights in order to maintain liquidity;

     (8)  purchase securities of any issuer (except securities issued or
guaranteed by the U.S. Government, its agencies and instrumentalities, including
government-sponsored enterprises) if, as a result, with respect to 75% of its
total assets, more than 5% of the value of the Fund's total assets would be
invested in the securities of any one issuer or, with respect to 100% of its
total assets the Fund's ownership would be more than 10% of the outstanding
voting securities of such issuer; nor

     (9)  make loans, except that the Fund may purchase or hold debt
instruments, lend its portfolio securities or enter into repurchase agreement
transactions in accordance with its investment policies.

     With regard to fundamental investment restriction number (1) above, the
Fund intends to reserve freedom of action to have in excess of 25% of the value
of the respective total assets invested in obligations of the banking industry.
Regarding this fundamental concentration policy, the Fund may hold in excess of
25% of the value of the assets in obligations of the banking industry to the
extent that the Fund holds obligations with such credit enhancements as letters
of credit issued by domestic bank issuers, which will be considered to be
obligations of domestic banks.  The SEC staff's position is that the exclusion
with respect to banks may only be applied to domestic banks.  For this purpose,
the staff also takes the position that U.S. branches of foreign banks and
foreign branches of domestic banks may, if certain conditions are met, be
treated as "domestic banks".  The Company currently intends to consider only
obligations of "domestic banks" to be within the exclusion with respect to bank
obligations.

     Fundamental investment restriction number (8), above, is less restrictive
than Rule 2a-7 of the 1940 Act.  Nonetheless, it is the operating policy of the
Fund to comply with Rule 2a-7's diversification requirements.

                                       3
<PAGE>
 
The Prime Money Market Mutual and Treasury Money Market Mutual Funds may not:

     (1)  purchase common stocks and voting securities (including state,
municipal or industrial revenue bonds) except for securities of other investment
companies;

     (2)  borrow money or issue senior securities, except that each Fund may
borrow from banks or enter into reverse repurchase agreements for temporary
purposes in amounts up to one-third of the value of its total assets at the time
of such borrowing.  None of these Funds will purchase securities while its
borrowings (including reverse repurchase agreements) in excess of 5% of its
total assets are outstanding.  As a matter of non-fundamental policy, each Fund
intends to limit its investments in reverse repurchase agreements to no more
than 20% of its total assets;

     (3)  mortgage, pledge, or hypothecate any assets, except in connection with
any such borrowing and in amounts not in excess of one-third of the value of
each such Fund's total assets at the time of its borrowing. Securities held in
escrow or separate accounts in connection with a Fund's investment practices are
not deemed to be pledged for purposes of this investment restriction;

     (4)  purchase securities on margin, except for delayed delivery or when-
issued transactions or such short-term credits as are necessary for the
clearance of transactions; or make short sales of securities or, maintain a
short position;

     (5)  write put or call options;

     (6)  underwrite the securities of other issuers, except as each such Fund
may be deemed to be an underwriter in connection with the purchase or sale of
portfolio instruments in accordance with its investment objective and portfolio
management policies;

     (7)  invest in companies for the purpose of exercising control;

     (8)  make loans, except that each such Fund may purchase or hold debt
instruments in accordance with its investment objective and policies and may
enter into loans of portfolio securities and repurchase agreements;

     (9)  invest in securities of other investment companies, except as they may
be acquired as part of a merger, consolidation, acquisition of assets or where
otherwise permitted by the 1940 Act; nor

     (10)  lend its portfolio securities in excess of one-third of the value of
its total assets.

     Non-Fundamental Investment Policies
     -----------------------------------

     Each Fund has adopted the following non-fundamental policies which may be
changed by a majority vote of the Board of Directors of the Company at any time
and without approval of such Fund's shareholders.

                                       4
<PAGE>
 
     (1)  Each Fund may invest in shares of other open-end management investment
companies, subject to the limitations of Section 12(d)(1) of the 1940 Act.
Under the 1940 Act, a Fund's investment in such securities currently is limited
to , subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5%  of such Fund's net assets with respect to any one
investment company, and (iii) 10% of such Fund's net assets in the aggregate.
Other investment companies in which the Funds invest can be expected to charge
fees for operating expenses, such as investment advisory and administration
fees, that would be in addition to those charged by a Fund.

     (2)  Each Fund may not invest more than 10% of its net assets in illiquid
securities.  For this purpose, illiquid securities include, among others, (a)
securities that are illiquid by virtue of the absence of a readily available
market or legal or contractual restrictions on resale, (b) fixed time deposits
that are subject to withdrawal penalties and that have maturities of more than
seven days, and (c) repurchase agreements not terminable within seven days.

     (3)  Each Fund may invest up to 25% of its net assets in securities of
foreign governmental and foreign private issuers that are denominated in and pay
interest in U.S. dollars.

     (4)  Each Fund may lend securities from its portfolios to brokers, dealers
and financial institutions, in amounts not to exceed (in the aggregate) one-
third of such Fund's total assets.  Any such loans of portfolio securities will
be fully collateralized based on values that are marked to market daily.  The
Funds will not enter into any portfolio security lending arrangement having a
duration of longer than one year.

                  ADDITIONAL PERMITTED INVESTMENT ACTIVITIES


     Set forth below are descriptions of certain investments and additional
investment policies for the Funds.

     Asset-Backed Securities
     -----------------------

     The Prime Money Market Mutual and Treasury Money Market Mutual Funds may
purchase asset-backed securities, which are securities backed by installment
contracts, credit-card receivables or other assets.  Asset-backed securities
represent interests in "pools" of assets in which payments of both interest and
principal on the securities are made monthly, thus in effect "passing through"
monthly payments made by the individual borrowers on the assets that underlie
the securities, net of any fees paid to the issuer or guarantor of the
securities.  The average life of asset-backed securities varies with the
maturities of the underlying instruments and is likely to be substantially less
than the original maturity of the assets underlying the securities as a result
of prepayments.  For this and other reasons, an asset-backed security's stated
maturity may be shortened, and the security's total return may be difficult to
predict precisely.

                                       5
<PAGE>
 
     Bank Obligations
     ----------------

     The Funds may invest in bank obligations, including certificates of
deposit, time deposits, bankers' acceptances and other short-term obligations of
domestic banks, foreign subsidiaries of domestic banks, foreign branches of
domestic banks, and domestic and foreign branches of foreign banks, domestic
savings and loan associations and other banking institutions.  With respect to
such securities issued by foreign branches of domestic banks, foreign
subsidiaries of domestic banks, and domestic and foreign branches of foreign
banks, a Fund may be subject to additional investment risks that are different
in some respects from those incurred by a fund which invests only in debt
obligations of U.S. domestic issuers.  Such risks include possible future
political and economic developments, the possible imposition of foreign
withholding taxes on interest income payable on the securities, the possible
establishment of exchange controls or the adoption of other foreign governmental
restrictions which might adversely affect the payment of principal and interest
on these securities and the possible seizure or nationalization of foreign
deposits.  In addition, foreign branches of U.S. banks and foreign banks may be
subject to less stringent reserve requirements and to different accounting,
auditing, reporting and recordkeeping standards than those applicable to
domestic branches of U.S. banks.

     Certificates of deposit are negotiable certificates evidencing the
obligation of a bank to repay funds deposited with it for a specified period of
time.

     Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time at a stated interest rate.  Time
deposits which may be held by a Fund will not benefit from insurance from the
Bank Insurance Fund or the Savings Association Insurance Fund administered by
the Federal Deposit Insurance Corporation.  Bankers' acceptances are credit
instruments evidencing the obligation of a bank 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 face amount of the instrument upon maturity.  The other short-
term obligations may include uninsured, direct obligations, bearing fixed,
floating- or variable-interest rates.

     Commercial Paper
     ----------------

     The Funds may invest in commercial paper. Commercial paper includes short-
term unsecured promissory notes, variable rate demand notes and variable rate
master demand notes issued by domestic and foreign bank holding companies,
corporations and financial institutions as well as similar taxable instruments
issued by government agencies and instrumentalities.

     Floating- and Variable-Rate Obligations
     ---------------------------------------

     The Funds may purchase floating- and variable-rate obligations.  Each Fund
may purchase floating- and variable-rate demand notes and bonds.  These
obligations may have stated maturities in excess of thirteen months, but they
permit the holder to demand payment of principal at any time, or at specified
intervals not exceeding thirteen months.  Variable-rate demand notes include
master demand notes that are obligations that permit a Fund to invest
fluctuating amounts, which may change daily without penalty, pursuant to direct
arrangements between the Fund, as lender, and the borrower.  The interest rates
on these notes may fluctuate 

                                       6
<PAGE>
 
from time to time. The issuer of such obligations ordinarily has a corresponding
right, after a given period, to prepay in its discretion the outstanding
principal amount of the obligations plus accrued interest upon a specified
number of days' notice to the holders of such obligations. The interest rate on
a floating-rate demand obligation is based on a known lending rate, such as a
bank's prime rate, and is adjusted automatically each time such rate is
adjusted. The interest rate on a variable-rate demand obligation is adjusted
automatically at specified intervals. Frequently, such obligations are secured
by letters of credit or other credit support arrangements provided by banks.
Because these obligations are direct lending arrangements between the lender and
borrower, it is not contemplated that such instruments generally will be traded,
and there generally is no established secondary market for these obligations,
although they are redeemable at face value. Accordingly, where these obligations
are not secured by letters of credit or other credit support arrangements, a
Fund's right to redeem is dependent on the ability of the borrower to pay
principal and interest on demand. Such obligations frequently are not rated by
credit rating agencies and each Fund may invest in obligations which are not so
rated only if Wells Fargo Bank determines that at the time of investment the
obligations are of comparable quality to the other obligations in which such
Fund may invest. Wells Fargo Bank, on behalf of each Fund, considers on an
ongoing basis the creditworthiness of the issuers of the floating- and variable-
rate demand obligations in such Fund's portfolio. No Fund will invest more than
10% of the value of its total net assets in floating- or variable-rate demand
obligations whose demand feature is not exercisable within seven days. Such
obligations may be treated as liquid, provided that an active secondary market
exists.

     Foreign Obligations
     -------------------

     Each Fund may invest up to 25% of its assets in high-quality, short-term
(thirteen months or less) debt obligations of foreign branches of U.S. banks or
U.S. branches of foreign banks that are denominated in and pay interest in U.S.
dollars.  Investments in foreign obligations involve certain considerations that
are not typically associated with investing in domestic obligations.  There may
be less publicly available information about a foreign issuer than about a
domestic issuer.  Foreign issuers also are not subject to the same uniform
accounting, auditing and financial reporting standards or governmental
supervision as domestic issuers.  In addition, with respect to certain foreign
countries, taxes may be withheld at the source under foreign income tax laws and
there is a possibility of expropriation or confiscatory taxation, political or
social instability, or diplomatic developments that could affect adversely
investments in, the liquidity of, and the ability to enforce contractual
obligations with respect to, securities of issuers located in those countries.

     Forward Commitments, When-Issued Purchases and Delayed-Delivery
     ---------------------------------------------------------------
Transactions
- ------------

     Each Fund may purchase or sell securities on a when-issued or delayed-
delivery basis and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. Securities purchased or
sold on a when-issued, delayed-delivery or forward commitment basis involve a
risk of loss if the value of the security to be purchased declines, or the value
of the security to be sold increases, before the settlement date.  Although each
Fund will generally purchase securities with the intention of acquiring them, a
Fund may dispose of 

                                       7
<PAGE>
 
securities purchased on a when-issued, delayed-delivery or a forward commitment
basis before settlement when deemed appropriate by the adviser.

     Each Fund will segregate cash, U.S. Government obligations or other high-
quality debt instruments in an amount at least equal in value to the Fund's
commitments to purchase when-issued securities.  If the value of these assets
declines, the Fund will segregate additional liquid assets on a daily basis so
that the value of the segregated assets is equal to the amount of such
commitments.

     Illiquid Securities
     -------------------

     The Funds may invest in securities not registered under the 1933 Act and
other securities subject to legal or other restrictions on resale.  Because such
securities may be less liquid than other investments, they may be difficult to
sell promptly at an acceptable price.  Delay or difficulty in selling securities
may result in a loss or be costly to a Fund.  Each Fund may invest up to 10% of
its assets in net illiquid securities.

     Letters of Credit
     -----------------

     Certain of the debt obligations (including municipal securities,
certificates of participation, commercial paper and other short-term
obligations) which the Funds may purchase may be backed by an unconditional and
irrevocable letter of credit of a bank, savings and loan association or
insurance company which assumes the obligation for payment of principal and
interest in the event of default by the issuer.  Only banks, savings and loan
associations and insurance companies which, in the opinion of Wells Fargo Bank,
are of comparable quality to issuers of other permitted investments of each such
Fund may be used for letter of credit-backed investments.

     Loans of Portfolio Securities
     -----------------------------

     The Funds may lend their portfolio securities to brokers, dealers and
financial institutions, provided:  (1) the loan is secured continuously by
collateral consisting of U.S. Government securities or cash or letters of credit
maintained on a daily marked-to-market basis in an amount at least equal to the
current market value of the securities loaned; (2) the Funds may at any time
call the loan and obtain the return of the securities loaned within five
business days; (3) the Funds will receive any interest or dividends paid on the
loaned securities; and (4) the aggregate market value of securities loaned will
not at any time exceed one third of the total assets of a particular Fund.

     A Fund will earn income for lending its securities because cash collateral
pursuant to such loans will be invested in short-term money market instruments.
In connection with lending securities, the Funds may pay reasonable finders,
administrative and custodial fees.  A Fund will not enter into any security
lending arrangement having a duration longer than one year.  Loans of securities
involve a risk that the borrower may fail to return the securities or may fail
to provide additional collateral. In either case, a Fund could experience delays
in recovering securities or collateral or could lose all or part of the value of
the loaned securities.  When a Fund lends its securities, it continues to
receive interest or dividends on the securities loaned and may 

                                       8
<PAGE>
 
simultaneously earn interest on the collateral received from the borrower or
from the investment of cash collateral in readily marketable, high-quality,
short-term obligations. Although voting rights, or rights to consent, attendant
to securities on loan pass to the borrower, such loans may be called at any time
and will be called so that the securities may be voted by a Fund if a material
event affecting the investment is to occur. A Fund may pay a portion of the
interest and fees earned from securities lending to a borrower or a placing
broker. Borrowers and placing brokers may not be affiliated, directly or
indirectly, with Wells Fargo Bank, Stephens Inc. or any of their affiliates.

     Mortgage-Backed Securities
     --------------------------

     The Prime Money Market Mutual and Treasury Money Market Mutual Funds may
invest in mortgage-backed securities, including those representing an undivided
ownership interest in a pool of mortgages, such as certificates of the
Government National Mortgage Association ("GNMA") and the Federal Home Loan
Mortgage Corporation ("FHLMC"). These certificates are in most cases pass-
through instruments, through which the holder receives a share of all interest
and principal payments from the mortgages underlying the certificate, net of
certain fees. The average life of a mortgage-backed security varies with the
underlying mortgage instruments, which generally have maximum maturities of 40
years. The average life is likely to be substantially less than the original
maturity of the mortgage pools underlying the securities as the result of
prepayments, mortgage refinancings or foreclosure. Mortgage prepayment rates are
affected by factors including the level of interest rates, general economic
conditions, the location and age of the mortgage and other social and
demographic conditions. Such prepayments are passed through to the registered
holder with the regular monthly payments of principal and interest and have the
effect of reducing future payments.

     There are risks inherent in the purchase of mortgage-backed securities. For
example, these securities are subject to a risk that default in payment will
occur on the underlying mortgages. In addition to default risk, these securities
are subject to the risk that prepayment on the underlying mortgages will occur
earlier or later or at a lesser or greater rate than expected. To the extent
that adviser's assumptions about prepayments are inaccurate, these securities
may expose the Funds, to significantly greater market risks than expected.

     Municipal Bonds
     ---------------

     The Money Market Mutual, National Tax-Free Money Market Mutual and Prime
Money Market Mutual Funds may invest in municipal bonds.  The two principal
classifications of municipal bonds are "general obligation" and "revenue" bonds.
Municipal bonds are debt obligations issued to obtain funds for various public
purposes, including the construction of a wide range of public facilities such
as bridges, highways, housing, hospitals, mass transportation, schools, streets,
and water and sewer works.  Other purposes for which municipal bonds may be
issued include the refunding of outstanding obligations and obtaining funds for
general operating expenses or to loan to other public institutions and
facilities.  Industrial development bonds are a specific type of revenue bond
backed by the credit and security of a private user.  Certain types of
industrial development bonds are issued by or on behalf of public authorities to
obtain funds to provide privately-operated housing facilities, sports
facilities, convention or trade show 

                                       9
<PAGE>
 
facilities, airport, mass transit, port or parking facilities, air or water
pollution control facilities and certain local facilities for water supply, gas,
electricity, or sewage or solid waste disposal. The Funds [NTF YES, CONFIRM PMMM
AND MMM] MAY NOT INVEST 25% OR MORE OF THEIR RESPECTIVE ASSETS IN INDUSTRIAL
DEVELOPMENT BONDS. Assessment bonds, wherein a specially created district or
project area levies a tax (generally on its taxable property) to pay for an
improvement or project may be considered a variant of either category. There
are, of course, other variations in the types of municipal bonds, both within a
particular classification and between classifications, depending on numerous
factors.

     The [TREASURY MONEY MARKET MUTUAL] Fund may invest in municipal lease
obligations.  Wells Fargo Bank makes determinations concerning the liquidity of
a municipal lease obligation based on factors deemed relevant.  These factors
may include, among others: (1) the frequency of trades and quotes for the
obligation; (2) the number of dealers willing to purchase or sell the security
and the number of other potential buyers; (3) the willingness of dealers to
undertake to make a market in the security; and (4) the nature of the
marketplace trades, including the time needed to dispose of the security, the
method of soliciting offers, and the mechanics of transfer. In addition, the
general credit quality of the municipality and the essentiality to the
municipality of the property covered by the lease may be considered. In
evaluating the credit quality of a municipal lease obligation, the factors to be
considered might include: (1) whether the lease can be canceled; (2) what
assurance there is that the assets represented by the lease can be sold; (3) the
strength of the lessee's general credit (e.g., its debt, administrative,
economic, and financial characteristics); (4) the likelihood that the
municipality will discontinue appropriating funding for the leased property
because the property is no longer deemed essential to the operations of the
municipality (e.g., the potential for an "event of the nonappropriation"); and
(5) the legal recourse in the event of failure to appropriate.

     From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on municipal obligations. For example, under federal tax legislation
enacted in 1986, interest on certain private activity bonds must be included in
an investor's alternative minimum taxable income, and corporate investors must
treat all tax-exempt interest as an item of tax preference.  Opinions relating
to the validity of municipal obligations and to the exemption of interest
thereon from federal income tax are rendered by bond counsel to the respective
issuers at the time of issuance. Neither the Funds nor the adviser will review
the proceedings relating to the issuance of municipal obligations or the basis
for such opinions.

     Certain of the municipal obligations held by a Fund may be insured as to
the timely payment of principal and interest. The insurance policies usually are
obtained by the issuer of the municipal obligation at the time of its original
issuance. In the event that the issuer defaults on interest or principal
payment, the insurer will be notified and will be required to make payment to
the bondholders. There is, however, no guarantee that the insurer will meet its
obligations. In addition, such insurance does not protect against market
fluctuations caused by changes in interest rates and other factors. The Tax-Free
Funds may, from time to time, invest more than 25% of their assets in municipal
obligations covered by insurance policies.

                                      10
<PAGE>
 
     The values of outstanding municipal securities will vary as a result of
changing market evaluations of the ability of their issuers to meet the interest
and principal payments (i.e., credit risk).  Such values also will change in
response to changes in the interest rates payable on new issues of municipal
securities (i.e., market risk).  Should such interest rates rise, the values of
outstanding securities, including those held in a Fund's portfolio, will decline
and (if purchased at par value) sell at a discount.  If interests rates fall,
the values of outstanding securities will generally increase and (if purchased
at par value) sell at a premium.  Changes in the value of municipal securities
held in the Fund's portfolio arising from these or other factors will cause
changes in the net asset value per share.

     Municipal Notes
     ---------------

     The Money Market Mutual and National Tax-Free Money Market Mutual Funds may
invest in municipal notes.  Municipal notes include, but are not limited to, tax
anticipation notes ("TANs"), bond anticipation notes ("BANs"), revenue
anticipation notes ("RANs") and construction loan notes.  Notes sold as interim
financing in anticipation of collection of taxes, a bond sale or receipt of
other revenues are usually general obligations of the issuer.

     TANs.  An uncertainty in a municipal issuer's capacity to raise taxes as a
result of such events as a decline in its tax base or a rise in delinquencies
could adversely affect the issuer's ability to meet its obligations on
outstanding TANs.  Furthermore, some municipal issuers mix various tax proceeds
into a general fund that is used to meet obligations other than those of the
outstanding TANs.  Use of such a general fund to meet various obligations could
affect the likelihood of making payments on TANs.

     BANs.  The ability of a municipal issuer to meet its obligations on its
BANs is primarily dependent on the issuer's adequate access to the longer term
municipal bond market and the likelihood that the proceeds of such bond sales
will be used to pay the principal of, and interest on, BANs.

     RANs.  A decline in the receipt of certain revenues, such as anticipated
revenues from another level of government, could adversely affect an issuer's
ability to meet its obligations on outstanding RANs.  In addition, the
possibility that the revenues would, when received, be used to meet other
obligations could affect the ability of the issuer to pay the principal of, and
interest on, RANs.

     The values of outstanding municipal securities will vary as a result of
changing market evaluations of the ability of their issuers to meet the interest
and principal payments (i.e., credit risk).  Such values also will change in
response to changes in the interest rates payable on new issues of municipal
securities (i.e., market risk).  Should such interest rates rise, the values of
outstanding securities, including those held in a Fund's portfolio, will decline
and (if purchased at par value) sell at a discount.  If interests rates fall,
the values of outstanding securities will generally increase and (if purchased
at par value) sell at a premium.  Changes in the value of municipal securities
held in the Fund's portfolio arising from these or other factors will cause
changes in the net asset value per share of the Fund.

<PAGE>
 
     Other Investment Companies
     --------------------------

     The Funds may invest in shares of other open-end management investment
companies, up to the limits prescribed in Section 12(d) of the 1940 Act.  Under
the 1940 Act, a Fund's investment in such securities currently is limited to,
subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5% of such Fund's net assets with respect to any one
investment company and (iii) 10% of such Fund's net assets in aggregate.  Other
investment companies in which the Funds invest can be expected to charge fees
for operating expenses such as investment advisory and administration fees, that
would be in addition to those charged by the Funds.

     Repurchase Agreements
     ---------------------

     Each Fund may enter into repurchase agreements, wherein the seller of a
security to the Fund agrees to repurchase that security from the Fund at a
mutually agreed upon time and price.  A Fund may enter into repurchase
agreements only with respect to securities that could otherwise be purchased by
the Fund.  All repurchase agreements will be fully collateralized at 102% based
on values that are marked to market daily.  The maturities of the underlying
securities in a repurchase agreement transaction may be greater than twelve
months, although the maximum term of a repurchase agreement will always be less
than twelve months.  If the seller defaults and the value of the underlying
securities has declined, a Fund may incur a loss.  In addition, if bankruptcy
proceedings are commenced with respect to the seller of the security, the Fund's
disposition of the security may be delayed or limited.

     Each Fund may not enter into a repurchase agreement with a maturity of more
than seven days, if, as a result, more than 10% of the market value of such
Fund's total net assets would be invested in repurchase agreements with
maturities of more than seven days, restricted securities and illiquid
securities.  A Fund will only enter into repurchase agreements with primary
broker/dealers and commercial banks that meet guidelines established by the
Board of Directors and that are not affiliated with the investment adviser.  The
Funds may participate in pooled repurchase agreement transactions with other
funds advised by Wells Fargo Bank.

     Borrowing and Reverse Repurchase Agreements
     -------------------------------------------

     The Prime Money Market Mutual and Treasury Money Market Mutual Funds intend
to limit their borrowings (including reverse repurchase agreements) during the
current fiscal year to not more than 10% of their net assets.  At the time a
Fund enters into a reverse repurchase agreement (an agreement under which the
Fund sells portfolio securities and agrees to repurchase them at an agreed-upon
date and price), it will place in a segregated custodial account liquid assets
such as U.S. Government securities or other liquid high-grade debt securities
having a value equal to or greater than the repurchase price (including accrued
interest) and will subsequently monitor the account to ensure that such value is
maintained. Reverse repurchase agreements involve the risk that the market value
of the securities sold by a Fund may decline below the price at which the Fund
is obligated to repurchase the securities. Reverse repurchase agreements are
considered to be borrowings under the 1940 Act.

                                      12
<PAGE>
 
     Taxable Investments
     -------------------

     The National Tax-Free Money Market Mutual Fund may make certain taxable
investments.  Pending the investment of proceeds from sales of portfolio
securities or in anticipation of redemptions or to maintain a "defensive"
posture when, in the opinion of Wells Fargo Bank, as investment adviser, it is
advisable to do so because of market conditions, the National Tax-Free Money
Market Mutual Fund may elect to invest temporarily up to 20% of the current
value of its net assets in cash reserves including the following taxable high-
quality money market instruments: (I) U.S. Government obligations; (ii)
negotiable certificates of deposit, bankers' acceptances and fixed time deposits
and other obligations of domestic banks (including foreign branches) that have
more than $1 billion in total assets at the time of investment and are members
of the Federal Reserve System or are examined by the Comptroller of the Currency
or whose deposits are insured by the FDIC; (iii) commercial paper rated at the
date of purchase "P-1" by Moody's or "A-1+" or "A-1" by S&P; (iv) certain
repurchase agreements; and (v) high-quality municipal obligations, the income
from which may or may not be exempt from federal income taxes.

     Moreover, the National Tax-Free Money Market Mutual Fund may invest
temporarily more than 20% of its total assets in such securities and in high-
quality, short-term municipal obligations the interest on which is not exempt
from federal income taxes to maintain a temporary defensive posture or in an
effort to improve after-tax yield to the Fund's interestholders when, in the
opinion of Wells Fargo Bank, as investment adviser, it is advisable to do so
because of unusual market conditions.

     Unrated and Downgraded Investments
     ----------------------------------

     The Funds may purchase instruments that are not rated if, in the opinion of
Wells Fargo Bank the investment adviser, such obligations are of comparable
quality to other rated investments that are permitted to be purchased by the
Fund.  The Fund may purchase unrated instruments only if they are purchased in
accordance with the Fund's procedures adopted by Company's Board of Directors in
accordance with Rule 2a-7 under the 1940 Act.  After purchase by the Fund, a
security may cease to be rated or its rating may be reduced below the minimum
required for purchase by the Fund.  In the event that a portfolio security
ceases to be an "Eligible Security" or no longer "presents minimal credit
risks," immediate sale of such security is not required, provided that the Board
of Directors has determined that disposal of the portfolio security would not be
in the best interests of the Fund.  To the extent the ratings given by Moody's
or S&P may change as a result of changes in such organizations or their rating
systems, the Fund will attempt to use comparable ratings as standards for
investments in accordance with the investment policies.  The ratings of Moody's
and S&P are more fully described in the Appendix.

     U.S. Government and U.S. Treasury Obligations
     ---------------------------------------------

     The Funds may invest in obligations of agencies and instrumentalities of
the U.S. Government ("U.S. Government obligations").  The Treasury Money Market
Mutual Fund may invest only in U.S. Government obligations issued or guaranteed
by the U.S. Treasury.  Payment of principal and interest on U.S. Government
obligations (i) may be backed by the full faith and 

                                      13
<PAGE>
 
credit of the United States (as with U.S. Treasury bills and GNMA certificates)
or (ii) may be backed solely by the issuing or guaranteeing agency or
instrumentality itself (as with FNMA notes). In the latter case investors must
look principally to the agency or instrumentality issuing or guaranteeing the
obligation for ultimate repayment, which agency or instrumentality may be
privately owned. There can be no assurance that the U.S. Government will provide
financial support to its agencies or instrumentalities where it is not obligated
to do so. In addition, U.S. Government obligations are subject to fluctuations
in market value due to fluctuations in market interest rates. As a general
matter, the value of debt instruments, including U.S. Government obligations,
declines when market interest rates increase and rises when market interest
rates decrease. Certain types of U.S. Government obligations are subject to
fluctuations in yield or value due to their structure or contract terms.

     The Treasury Money Market Mutual Fund may invest only in obligations issued
or guaranteed by the U.S. Treasury such as bills, notes, bonds and certificates
of indebtedness, and in notes and repurchase agreements collateralized or
secured by such obligations ("U.S. Treasury obligations").  U.S. Treasury notes,
bills and bonds differ mainly in the length of their maturity.  The U.S.
Treasury obligations in which the Fund invests may also include "U.S. Treasury
STRIPS," interests in U.S. Treasury obligations reflected in the Federal
Reserve-Book Entry System that represent ownership in either the future interest
payments or the future principal payments on the U.S. Treasury obligations.
U.S. Treasury Strips are "stripped securities."  Stripped securities are issued
at a discount to their face value and may exhibit greater price volatility than
ordinary debt securities because of the manner in which their principal and
interest are paid to investors.  The Treasury Money Market Mutual and Government
Money Market Mutual Funds may invest in U.S. Treasury STRIPS.

     The Funds may attempt to increase yields by trading to take advantage of
short-term market variations.  This policy could result in high portfolio
turnover, which should not adversely affect the Funds since they do not
ordinarily pay brokerage commissions on the purchase of short-term debt
obligations.

     Nationally Recognized Statistical Ratings Organizations
     -------------------------------------------------------

     The ratings of Moody's Investors Service, Inc., Standard & Poor's Ratings
Group, Duff & Phelps Credit Rating Co., Fitch Investors Service, Inc., Thomson
Bank Watch and IBCA Inc. represent their opinions as to the quality of debt
securities. It should be emphasized, however, that ratings are general and not
absolute standards of quality, and debt securities with the same maturity,
interest rate and rating may have different yields while debt securities of the
same maturity and interest rate with different ratings may have the same yield.
Subsequent to purchase by a Fund, an issue of debt securities may cease to be
rated or its rating may be reduced below the minimum rating required for
purchase by a Fund. The adviser will consider such an event in determining
whether the Fund involved should continue to hold the obligation.

     The payment of principal and interest on debt securities purchased by the
Funds depends upon the ability of the issuers to meet their obligations. An
issuer's obligations under its debt securities are subject to the provisions of
bankruptcy, insolvency, and other laws affecting the rights 

                                      14
<PAGE>
 
and remedies of creditors, such as the Federal Bankruptcy Code, and laws, if
any, which may be enacted by federal or state legislatures extending the time
for payment of principal or interest, or both, or imposing other constraints
upon enforcement of such obligations or, in the case of governmental entities,
upon the ability of such entities to levy taxes. The power or ability of an
issuer to meet its obligations for the payment of interest and principal of its
debt securities may be materially adversely affected by litigation or other
conditions. Further, it should also be noted with respect to all municipal
obligations issued after August 15, 1986 (August 31, 1986 in the case of certain
bonds), the issuer must comply with certain rules formerly applicable only to
industrial development bonds which, if the issuer fails to observe them, could
cause interest on the municipal obligations to become taxable retroactive to the
date of issue.

                                 RISK FACTORS


     Investments in a Fund are not bank deposits or obligations of Wells Fargo
Bank, are not insured by the FDIC and are not insured or guaranteed against loss
of principal.  Therefore, you should be willing to accept some risk with money
you invest in a Fund. Although the Funds seek to maintain a stable net asset
value of $1.00 per share, there is no assurance that they will be able to do so.
The Funds may not achieve as high a level of current income as other mutual
funds that do not limit their investment to the high credit quality instruments
in which the Funds invest.  As with all mutual funds, there can be no assurance
that a Fund will achieve its investment objective.

     The Funds, under the 1940 Act, must comply with certain investment criteria
designed to provide liquidity, reduce risk, and allow the Funds to maintain a
stable net asset value of $1.00 per share.  The Funds' dollar-weighted average
portfolio maturity must not exceed 90 days.  Any security that a Fund purchases
must have a remaining maturity of not more than 397 days (13 months).  In
addition, any security that a Fund purchases must present minimal credit risks
and be of "high quality," or in the case of the Treasury Money Market Mutual
Fund, be of the "highest quality."  "High quality" means to be rated in the top
two rating categories and "highest quality" means to be rated only in the top
rating category, by the requisite NRSROs or, if unrated, determined to be of
comparable quality to such rated securities by Wells Fargo Bank, as the Funds'
investment adviser, under guidelines adopted by the Board of Directors of the
Company.

     Each Fund seeks to reduce risk by investing its assets in securities of
various issuers.  As such, the Money Market Mutual Fund and the National Tax-
Free Money Market Mutual Fund are considered to be diversified for purposes of
the 1940 Act. In addition, the Funds emphasize safety of principal and high
credit quality. In particular, the internal investment policies of the
investment adviser prohibit the purchase of many types of floating-rate
derivative securities that are considered potentially volatile. The following
types of derivative securities ARE NOT permitted investments for the Funds:

          . capped floaters (on which interest is not paid when market rates
            move above a certain level);

                                      15
<PAGE>
 
          . leveraged floaters (whose interest rate reset provisions are based
            on a formula that magnifies changes in interest rates);

          . range floaters (which do not pay any interest if market interest
            rates move outside of a specified range);

          . dual index floaters (whose interest rate reset provisions are tied
            to more than one index so that a change in the relationship between
            these indices may result in the value of the instrument falling
            below face value); and

          . inverse floaters (which reset in the opposite direction of their
            index).

     Additionally, the Funds may not invest in securities whose interest rate
reset provisions are tied to an index that materially lags short-term interest
rates, such as Cost of Funds Index floaters.  The Funds may invest only in
variable or floating-rate securities that bear interest at a rate that resets
quarterly or more frequently and that resets based on changes in standard money
market rate indices such as U.S. Treasury bills, London Interbank Offered Rate
or LIBOR, the prime rate, published commercial paper rates, federal funds rates,
Public Securities Associates floaters or JJ Kenney index floaters.

     The Treasury Money Market Mutual Fund restricts its investment to U.S.
Treasury obligations that meet all of the standards described above.
Obligations issued or guaranteed by the U.S. Treasury have historically involved
little risk of loss of principal if held to maturity.  However, due to
fluctuations in interest rates, the market value of such obligations may vary
during the period a shareholder owns shares of the Fund.  It should be noted
that neither the United States, nor any agency or instrumentality thereof, has
guaranteed, sponsored or approved the Fund or its shares.

     The portfolio debt instruments of the Funds are subject to credit and
interest-rate risk. Credit risk is the risk that issuers of the debt instruments
in which the Funds invest may default on the payment of principal and/or
interest.  Interest-rate risk is the risk that increases in market interest
rates may adversely affect the value of the debt instruments in which the Funds
invest and hence the value of your investment in a Fund.

     Generally, securities in which the Funds invest will not earn as high a
yield as securities of longer maturity and/or of lesser quality that are more
subject to market volatility.  Each Fund attempts to maintain the value of its
shares at a constant $1.00 per share, although there can be no assurance that a
Fund will always be able to do so.

                                  MANAGEMENT

</TABLE>

     As of January 1, 1998, Peter G. Gordon will replace Robert M. Joses on the
Board of Directors of the Wells Fargo Fund Complex.

     Directors of the Company are compensated annually by the Company and by all
the registrants in each fund complex they serve as indicated above and also are
reimbursed for all out-of-pocket expenses relating to attendance at board
meetings.  The Company, Stagecoach Trust and Life & Annuity Trust are considered
to be members of the same fund complex as such term is defined in Form N-1A
under the 1940 Act (the "Wells Fargo Fund Complex").  Overland Express Funds,
Inc. and Master Investment Trust, two investment companies previously advised by
Wells Fargo Bank, were part of the Wells Fargo Fund Complex prior to December
12, 1997.  These companies are no longer part of the Wells Fargo Fund Complex.
MasterWorks Funds Inc., Master Investment Portfolio, and Managed Series
Investment Trust together form a separate fund complex (the "BGFA Fund
Complex").  Each of the Directors and Officers of the Company serves in the
identical capacity as directors and officers or as trustees and/or officers of
each registered open-end management investment company in both the Wells Fargo
and BGFA Fund Complexes, except for Joseph N. Hankin, who only serves the
aforementioned members of the Wells Fargo Fund 

                                      18

Complex. The Directors are compensated by other companies and trusts within a
fund complex for their services as directors/trustees to such companies and
trusts. Currently the Directors do not receive any retirement benefits or
deferred compensation from the Company or any other member of each fund complex.

     As of the date of this SAI, Directors and Officers of the Company as a
group beneficially owned less than 1% of the outstanding shares of the Company.

to the Funds.  As investment adviser, Wells Fargo Bank furnishes investment
guidance and policy direction in connection with the daily portfolio management
of the Funds.  Wells Fargo Bank furnishes to the Company's Board of Directors
periodic reports on the investment strategy and performance of each Fund.  Wells
Fargo Bank provides the Funds with, among other things, money market security
and fixed-income research, analysis and statistical and economic data and
information concerning interest rate and securities markets trends, portfolio
composition, and credit conditions.

Mutual Funds, not to exceed 0.25%, and from the National Tax-Free Money Market
Mutual Fund, not to exceed 0.20%, on an annualized basis, of the average daily
net assets of the class of shares owned of record or beneficially by the
customers of the Servicing Agent during the period for which payment is being
made.  The Servicing Plans and related forms of shareholder servicing agreements
were approved by the Company's Board of Directors and  provide that a Fund shall
not be obligated to make any payments under such Plans or related Agreements
that exceed the maximum amounts payable under the Conduct Rules of the National

the Money Market Mutual Fund, Wells Fargo Bank was entitled to receive a per
account fee plus transaction fees and reimbursement of out-of-pocket expenses,
with a minimum of $3,000 per month, unless net assets of the Fund were under $20
million. For as long as the Fund's assets remained under $20 million, the Fund
was not charged any transfer agency fees.

     For the nine-month period ended September 30, 1996, the Money Market Mutual

     For the nine-month period ended September 30, 1996, the National Tax-Free

     Prime Money Market Mutual and Treasury Money Market Mutual Funds.  Under
     ----------------------------------------------------------------        
the prior transfer agency agreement for the Institutional Class shares of the

the annual rate of 0.02% of the average daily net assets of the Institutional
Class shares of each Fund, as well as reimbursement for all reasonable out-of-
pocket expenses.  Furman Selz acted as Transfer Agent for the predecessor
portfolios.  Pacifica compensated Furman Selz for providing personnel and
facilities to perform transfer agency related services for Pacifica at a rate
intended to represent the cost of providing such services.

     UNDERWRITING COMMISSIONS.  The Institutional Class of each Fund does not

charge any front-end sales loads or contingent-deferred sales charges in
connection with the purchase and redemption of its shares, and therefore pays no
underwriting commissions to the Distributor.


                           PERFORMANCE CALCULATIONS

     The Funds may advertise certain yield and total return information.
Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown.  Yield and total return vary based on changes in 

                                      26
<PAGE>
 
the market conditions and the level of a Fund's expenses, and no reported
performance figure should be considered an indication of performance which may
be expected in the future.

     In connection with communicating its performance to current or prospective
shareholders, these figures may also be compared to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

     Performance information for a Fund or Class of shares in a Fund may be
useful in reviewing the performance of such Fund or Class of shares and for
providing a basis for comparison with investment alternatives.  The yield of a
Fund and the yield of a Class of shares in a Fund, however, may not be
comparable to the yields from investment alternatives because of differences in
the foregoing variables and differences in the methods used to value portfolio
securities, compute expenses and calculate yield.

     TOTAL RETURN:  The Funds may advertise certain total return information
     ------------                                                           
computed in the manner described in the Prospectus.  As and to the extent
required by the SEC, an average annual compound rate of return ("T") is computed
by using the redeemable value at the end of a specified period ("ERV") of a
hypothetical initial investment ("P") over a period of years ("n") according to
the following formula:  P(1+T)n=ERV.  In addition, as indicated in each
Prospectus, each Fund also may, at times, calculate total return based on net
asset value per share (rather than the public offering price), in which case the
figures would not reflect the effect of any sales charges that would have been
paid by an investor, or based on the assumption that a sales charge other than
the maximum sales charge (reflecting a Volume Discount) was assessed, provided
that total return data derived pursuant to the calculation described above also
are presented.

     Performance information may be advertised for non-standardized periods,
including year-to-date and other periods less than a year for the Funds.

     YIELD CALCULATIONS:  The Funds may, from time to time, include their
     ------------------                                                  
yields, tax-equivalent yields (if applicable) and effective yields in
advertisements or reports to shareholders or prospective investors.  Quotations
of yield for the Funds are based on the investment income per share earned
during a particular seven-day or thirty-day period, less expenses accrued during
a period ("net investment income") and are computed by dividing net investment
income by the offering price per share on the last date of the period, according
to the following formula:

                         YIELD - 2[(a - b + 1)/6/ -1]
                                    -----            
                                      Cd
                                        
     where a = dividends and interest earned during the period, b = expenses
accrued for the period (net of any reimbursements), c = the average daily number
of shares outstanding during the period that were entitled to receive dividends,
and d = the maximum offering price per share on the last day of the period.

     TAX-EQUIVALENT YIELD:  Quotations of tax-equivalent yield for a Tax-Free
     --------------------                                                    
Fund are calculated according the following formula:

                       TAX EQUIVALENT YIELD = ( E ) + t
                                               ---     
                                              1 - p
                           E = Tax-exempt yield
                           p = stated income tax rate
                           t = taxable yield

     EFFECTIVE YIELD:  Effective yields for the Funds are based on the change in
     ---------------                                                            
the value of a hypothetical investment (exclusive of capital changes) over a
particular seven-day (or thirty-day) period, less a pro-rata share of each
Fund's expenses accrued over that period (the "base period"), and stated as a
percentage of the investment at the start of the base period (the "base period
return").  The base period return is then annualized multiplying by 365/7 (or
365/30 for 

                                      28
<PAGE>
 
thirty-day yield), with the resulting yield figure carried to at least the
nearest hundredth of one percent. "Effective yield" for the Funds assumes that
all dividends received during the period have been reinvested. Calculation of
"effective yield" begins with the same "base period return" used in the
calculation of yield, which is then annualized to reflect weekly compounding
pursuant to the following formula:

         Effective Seven-Day Yield = [(Base Period Return +1)365/7]-1.

/2/ Since the Institutional class shares did not commence operations until
    December 12, 1997, yield information reflects the performance of the Fund's
    Class A shares. 

     From time to time and only to the extent the comparison is appropriate for
a Fund or a Class of shares, the Company may quote the performance or price-
earning ratio of a Fund or Class in advertising and other types of literature as
compared to the performance of the S&P Index, the Dow Jones Industrial Average,
the Lehman Brothers 20+ Treasury Index, the Lehman Brothers 5-7 Year Treasury
Index, Donoghue's Money Fund Averages, Real Estate Investment Averages (as
reported by the National Association of Real Estate Investment Trusts), Gold
Investment Averages (provided by World Gold Council), Bank Averages (which are
calculated from figures supplied by the U.S. League of Savings Institutions
based on effective annual rates of interest on both passbook and certificate
accounts), average annualized certificate of deposit rates (from the Federal
Reserve G-13 Statistical Releases or the Bank Rate Monitor), the Salomon One
Year Treasury Benchmark Index, the Consumer Price Index (as published by the
U.S. Bureau of Labor Statistics), other managed or unmanaged indices or
performance data of bonds, municipal securities, stocks or government securities
(including data provided by Ibbotson Associates), or by other services,
companies, publications or persons who monitor mutual funds on overall
performance or other criteria.  The S&P Index and the Dow Jones Industrial
Average are unmanaged indices of selected common stock prices.  The performance
of the Funds or a Class also may be compared to that of other mutual funds
having similar objectives.  This comparative performance could be expressed as a
ranking prepared by Lipper Analytical Services, Inc., CDA Investment
Technologies, Inc., Bloomberg Financial Markets or Morningstar, Inc.,
independent services which monitor the performance of mutual funds.  The 

                                      29
<PAGE>
 
Funds' performance will be calculated by relating net asset value per share at
the beginning of a stated period to the net asset value of the investment,
assuming reinvestment of all gains distributions and dividends paid, at the end
of the period. The Funds' comparative performance will be based on a comparison
of yields, as described above, or total return, as reported by Lipper, Survey
Publications, Donoghue or Morningstar, Inc.

     Any such comparisons may be useful to investors who wish to compare past
performance of the Funds or a Class with that of competitors.  Of course, past
performance cannot be a guarantee of future results.  The Company also may
include, from time to time, a reference to certain marketing approaches of the
Distributor, including, for example, a reference to a potential shareholder
being contacted by a selected broker or dealer.  General mutual fund statistics
provided by the Investment Company Institute may also be used.

     The Company also may use the following information in advertisements and
other types of literature, only to the extent the information is appropriate for
the Fund:  (i) the Consumer Price Index may be used to assess the real rate of
return from an investment in a Fund; (ii) other government statistics,
including, but not limited to, The Survey of Current Business, may be used to
illustrate investment attributes of a Fund or the general economic, business,
investment, or financial environment in which a Fund operates; (iii) the effect
of tax-deferred compounding on the investment returns of a Fund, or on returns
in general, may be illustrated by graphs, charts, etc., where such graphs or
charts would compare, at various points in time, the return from an investment
in a Fund (or returns in general) on a tax-deferred basis (assuming reinvestment
of capital gains and dividends and assuming one or more tax rates) with the
return on a taxable basis; and (iv) the sectors or industries in which a Fund
invests may be compared to relevant indices of stocks or surveys (e.g., S&P
Industry Surveys) to evaluate a Fund's historical performance or current or
potential value with respect to the particular industry or sector.

     In addition, the Company also may use, in advertisements and other types of
literature, information and statements: (1) showing that bank savings accounts
offer a guaranteed return of principal and a fixed rate of interest, but no
opportunity for capital growth; and (2)  describing Wells Fargo Bank, and its
affiliates and predecessors, as one of the first investment managers to advise
investment accounts using asset allocation and index strategies.  The Company
also may include in advertising and other types of literature information and
other data from reports and studies prepared by the Tax Foundation, including
information regarding federal and state tax levels and the related "Tax Freedom
Day."

     The Company also may discuss in advertising and other types of literature
that a Fund has been assigned a rating by a nationally recognized statistical
rating organization ("NRSRO"), such as Standard & Poor's Corporation.  Such
rating would assess the creditworthiness of the investments held by the Fund.
The assigned rating would not be a recommendation to purchase, sell or hold the
Fund's shares since the rating would not comment on the market price of the
Fund's shares or the suitability of the Fund for a particular investor.  In
addition, the assigned rating would be subject to change, suspension or
withdrawal as a result of changes in, or unavailability of, information relating
to the Fund or its investments.  The Company may compare the Fund's performance
with other investments which are assigned ratings by NRSROs.  

                                      30
<PAGE>
 
Any such comparisons may be useful to investors who wish to compare the Fund's
past performance with other rated investments.

     From time to time, the Funds may use the following statements, or
variations thereof, in advertisements and other promotional materials:  "Wells
Fargo Bank, as a Shareholder Servicing Agent for the Stagecoach Funds, provides
various services to its customers that are also shareholders of the Funds.
These services may include access to Stagecoach Funds' account information
through Automated Teller Machines (ATMs), the placement of purchase and
redemption requests for shares of the Funds through ATMs and the availability of
combined Wells Fargo Bank and Stagecoach Funds account statements."

     The Company also may disclose, in advertising and other types of
literature, information and statements that Wells Fargo Investment Management
("WFIM"), a division of Wells Fargo Bank, is listed in the top 100 by
Institutional Investor magazine in its July 1996 survey "America's Top 300 Money
Managers."  This survey ranks money managers in several asset categories.  The
Company may also disclose in advertising and other types of sales literature the
assets and categories of assets under management by the Company's investment
adviser.  The Company may also disclose in advertising and other types of sales
literature the assets and categories of assets under management by a fund's
investment adviser or sub-adviser and the total amount of assets and mutual fund
assets managed by Wells Fargo Bank.  As of December 31, 1996, Wells Fargo Bank
and its affiliates provided investment Advisory services for approximately $54
billion of assets of individual, trusts, estates and institutions and $20
billion of mutual fund assets.

     The Company also may discuss in advertising and other types of literature
the features, terms and conditions of Wells Fargo Bank accounts through which
investments in the Funds may be made via a "sweep" arrangement, including,
without limitation, the Managed Sweep Account, Money Market Checking Account,
California Tax-Free Money Market Checking Account, Money Market Access Account
and California Tax-Free Money Market Access Account (collectively, the "Sweep
Accounts").  Such advertisements and other literature may include, without
limitation, discussions of such terms and conditions as the minimum deposit
required to open a Sweep Account, a description of the yield earned on shares of
the Funds through a Sweep Account, a description of any monthly or other service
charge on a Sweep Account and any minimum required balance to waive such service
charges, any overdraft protection plan offered in connection with a Sweep
Account, a description of any ATM or check privileges offered in connection with
a Sweep Account and any other terms, conditions, features or plans offered in
connection with a Sweep Account.  Such advertising or other literature may also
include a discussion of the advantages of establishing and maintaining a Sweep
Account, and may include statements from customers as to the reasons why such
customers have established and maintained a Sweep Account.

     The Company may disclose in advertising and other types of literature that
investors can open and maintain Sweep Accounts over the Internet or through
other electronic channels (collectively, "Electronic Channels").  Such
advertising and other literature may discuss the investment options available to
investors, including the types of accounts and any applicable 

                                      31
<PAGE>
 
fees. Such advertising and other literature may disclose that Wells Fargo Bank
is the first major bank to offer an on-line application for a mutual fund
account that can be filled out completely through Electronic Channels.
Advertising and other literature may disclose that Wells Fargo Bank may maintain
Web sites, pages or other information sites accessible through Electronic
Channels (an "Information Site") and may describe the contents and features of
the Information Site and instruct investors on how to access the Information
Site and open a Sweep Account. Advertising and other literature may also
disclose the procedures employed by Wells Fargo Bank to secure information
provided by investors, including disclosure and discussion of the tools and
services for accessing Electronic Channels. Such advertising or other literature
may include discussions of the advantages of establishing and maintaining a
Sweep Account through Electronic Channels and testimonials from Wells Fargo Bank
customers or employees and may also include descriptions of locations where
product demonstrations may occur. The Company may also disclose the ranking of
Wells Fargo Bank as one of the largest money managers in the United States.


                       DETERMINATION OF NET ASSET VALUE

     Net asset value per share for the Institutional Class shares of the Prime
Money Market Mutual, Treasury Money Market Mutual and Money Market Mutual Funds
is determined as of 12:00 noon and 1:00 p.m. (Pacific time) on each day the NYSE
is open for business.  Net asset value per share for the Institutional shares of
the National Tax-Free Money Market Mutual Fund is determined as of 9:00 a.m. and
1:00 p.m. (Pacific time) on each day the NYSE is open for business.  Expenses
and fees, including advisory fees, are accrued daily and are taken into account
for the purpose of determining the net asset value of the Funds' shares.

     Each Fund uses the amortized cost method to determine the value of its
portfolio securities pursuant to Rule 2a-7 under the 1940 Act.  The amortized
cost method involves valuing a security at its cost and amortizing any discount
or premium over the period until maturity, regardless of the impact of
fluctuating interest rates on the market value of the security.  While this
method provides certainty in valuation, it may result in periods during which
the value, as determined by amortized cost, is higher or lower than the price
that the Funds would receive if the security were sold.  During these periods
the yield to a shareholder may differ somewhat from that which could be obtained
from a similar fund that uses a method of valuation based upon market prices.
Thus, during periods of declining interest rates, if the use of the amortized
cost method resulted in a lower value of the Funds' portfolio on a particular
day, a prospective investor in the Funds would be able to obtain a somewhat
higher yield than would result from investment in a fund using solely market
values, and existing Fund shareholders would receive correspondingly less
income.  The converse would apply during periods of rising interest rates.

     Rule 2a-7 provides that in order to value its portfolio using the amortized
cost method, a Fund must maintain a dollar-weighted average portfolio maturity
of 90 days or less, purchase securities having remaining maturities (as defined
in Rule 2a-7) of thirteen months or less and invest only in those high-quality
securities that are determined by the Board of Directors to 

                                      32
<PAGE>
 
present minimal credit risks. The maturity of an instrument is generally deemed
to be the period remaining until the date when the principal amount thereof is
due or the date on which the instrument is to be redeemed. However, Rule 2a-7
provides that the maturity of an instrument may be deemed shorter in the case of
certain instruments, including certain variable and floating rate instruments
subject to demand features. Pursuant to the Rule, the Board is required to
establish procedures designed to stabilize, to the extent reasonably possible, a
Fund's price per share as computed for the purpose of sales and redemptions at
$1.00. Such procedures include review of the Fund's portfolio holdings by the
Board of Directors, at such intervals as it may deem appropriate, to determine
whether the Fund's net asset value calculated by using available market
quotations deviates from $1.00 per share based on amortized cost. The extent of
any deviation will be examined by the Board of Directors. If such deviation
exceeds 1/2 of 1%, the Board will promptly consider what action, if any, will be
initiated. In the event the Board determines that a deviation exists that may
result in material dilution or other unfair results to investors or existing
shareholders, the Board will take such corrective action as it regards as
necessary and appropriate, including the sale of portfolio instruments prior to
maturity to realize capital gains or losses or to shorten average portfolio
maturity, withholding dividends or establishing a net asset value per share by
using available market quotations. It is the intention of the Funds to maintain
a per share net asset value of $1.00, but there can be no assurance that each
Fund will do so.

     Instruments having variable or floating interest rates or demand features
may be deemed to have remaining maturities as follows: (a) a government security
with a variable rate of interest readjusted no less frequently than every
thirteen months may be deemed to have a maturity equal to the period remaining
until the next readjustment of the interest rate; (b) an instrument with a
variable rate of interest, the principal amount of which is scheduled on the
face of the instrument to be paid in thirteen months or less, may be deemed to
have a maturity equal to the period remaining until the next readjustment of the
interest rate; (c) an instrument with a variable rate of interest that is
subject to a demand feature may be deemed to have a maturity equal to the longer
of the period remaining until the next readjustment of the interest rate or the
period remaining until the principal amount can be recovered through demand; (d)
an instrument with a floating rate of interest that is subject to a demand
feature may be deemed to have a maturity equal to the period remaining until the
principal amount can be recovered through demand; and (e) a repurchase agreement
may be deemed to have a maturity equal to the period remaining until the date on
which the repurchase of the underlying securities is scheduled to occur or,
where no date is specified but the agreement is subject to demand, the notice
period applicable to a demand for the repurchase of the securities.


                ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

     Shares may be purchased on any day a Fund is open for business (a "Business
Day").  The Funds are open Monday through Friday and are closed on federal bank
holidays.  Currently, those holidays are New Year's Day, President's Day, Martin
Luther King Jr. Day, Memorial Day, Independence Day, Labor Day, Columbus Day,
Veterans Day, Thanksgiving Day and Christmas Day.

                                      33
<PAGE>
 
     Payment for shares may, in the discretion of the adviser, be made in the
form of securities that are permissible investments for the Funds.  For further
information about this form of payment please contact Stephens.  In connection
with an in-kind securities payment, the Funds will require, among other things,
that the securities be valued on the day of purchase in accordance with the
pricing methods used by a Fund and that such Fund receives satisfactory
assurances that (i) it will have good and marketable title to the securities
received by it; (ii) that the securities are in proper form for transfer to the
Fund; and (iii) adequate information will be provided concerning the basis and
other matters relating to the securities.

     Under the 1940 Act, the Funds may suspend the right of redemption or
postpone the date of payment upon redemption for any period during which the
NYSE is closed (other than customary weekend and holiday closings, or during
which trading is restricted, or during which as determined by the SEC by rule or
regulation) an emergency exists as a result of which disposal or valuation of
portfolio securities is not reasonably practicable, or for such periods as the
SEC may permit.  The Company may also redeem shares involuntarily or make
payment for redemption in securities or other property if it appears appropriate
to do so in light of the Company's responsibilities under the 1940 Act.  In
addition, the Company may redeem shares involuntarily to reimburse the Funds for
any losses sustained by reason of the failure of a shareholders to make full
payment for shares purchased or to collect any charge relating to a transaction
effected for the benefit of a shareholder which is applicable to shares of a
Fund.


                            PORTFOLIO TRANSACTIONS

     The Company has no obligation to deal with any dealer or group of dealers
in the execution of transactions in portfolio securities.  Subject to policies
established by the Company's Board of Directors, Wells Fargo Bank is responsible
for each Fund's portfolio decisions and the placing of portfolio transactions.
In placing orders, it is the policy of the Company to obtain the best results
taking into account the dealer's general execution and operational facilities,
the type of transaction involved and other factors such as the dealer's risk in
positioning the securities involved.  While Wells Fargo Bank generally seeks
reasonably competitive spreads or commissions, the Funds will not necessarily be
paying the lowest spread or commission available.

     Purchases and sales of non-equity securities usually will be principal
transactions.  Portfolio securities normally will be purchased or sold from or
to dealers serving as market makers for the securities at a net price.  Each of
the Funds also will purchase portfolio securities in underwritten offerings and
may purchase securities directly from the issuer.  Generally, municipal
obligations and taxable money market securities are traded on a net basis and do
not involve brokerage commissions.  The cost of executing a Fund's portfolio
securities transactions will consist primarily of dealer spreads and
underwriting commissions.  Under the Act, persons affiliated with the Company
are prohibited from dealing with the Company as a principal in the purchase and
sale of securities unless an exemptive order allowing such transactions is
obtained from the Commission or an exemption is otherwise available.  The Fund
may purchase securities from underwriting syndicates of which Stephens or Wells
Fargo Bank is a member under certain 

                                      34
<PAGE>
 
conditions in accordance with the provisions of a rule adopted under the Act and
in compliance with procedures adopted by the Board of Directors.

     Wells Fargo Bank, as the Investment Adviser of each of the Funds, may, in
circumstances in which two or more dealers are in a position to offer comparable
results for a Fund portfolio transaction, give preference to a dealer that has
provided statistical or other research services to Wells Fargo Bank.  By
allocating transactions in this manner, Wells Fargo Bank is able to supplement
its research and analysis with the views and information of securities firms.
Information so received will be in addition to, and not in lieu of, the services
required to be performed by Wells Fargo Bank under the Advisory Contracts, and
the expenses of Wells Fargo Bank will not necessarily be reduced as a result of
the receipt of this supplemental research information.  Furthermore, research
services furnished by dealers through which Wells Fargo Bank places securities
transactions for a Fund may be used by Wells Fargo Bank in servicing its other
accounts, and not all of these services may be used by Wells Fargo Bank in
connection with advising the Funds.

     Brokerage Commissions.  The Funds did not pay any brokerage commissions on
     ---------------------                                                     
portfolio transactions for the nine-month period ended September 30, 1996 and
the six-month period ended March 31, 1997.

     Securities of Regular Broker/Dealers.  As of March 31, 1997, the Funds
     ------------------------------------                                  
owned securities of their "regular brokers or dealers" or their parents, as
defined in the Act as follows:

     Portfolio Turnover.  The portfolio turnover rate is not a limiting factor
     ------------------                                                       
when Wells Fargo Bank deems portfolio changes appropriate.  Changes may be made
in the portfolios consistent with the investment objectives and policies of the
Funds whenever such changes are believed to be in the 

                                      35
<PAGE>
 
best interests of the Funds and their shareholders. The portfolio turnover rate
is calculated by dividing the lesser of purchases or sales of portfolio
securities by the average monthly value of the Fund's portfolio securities. For
purposes of this calculation, portfolio securities exclude all securities having
a maturity when purchased of one year or less. Portfolio turnover generally
involves some expenses to the Funds, including brokerage commissions or dealer
mark-ups and other transaction costs on the sale of securities and the
reinvestment in other securities. Portfolio turnover also can generate short-
term capital gain tax consequences. Portfolio turnover rate is not a limiting
factor when Wells Fargo Bank deems portfolio changes appropriate.


                                 FUND EXPENSES

     From time to time, Wells Fargo Bank and Stephens may waive fees from the
Funds in whole or in part.  Any such waiver will reduce expenses and,
accordingly, have a favorable impact on a Fund's performance.  Except for the
expenses borne by Wells Fargo Bank and Stephens, the Company bears all costs of
its operations, including the compensation of its Directors who are not
affiliated with Stephens or Wells Fargo Bank or any of their affiliates;
advisory, shareholder servicing and administration fees; payments pursuant to
any Plan; interest charges; taxes; fees and expenses of its independent
accountants, legal counsel, transfer agent and dividend disbursing agent;
expenses of redeeming shares; expenses of preparing and printing prospectuses
(except the expense of printing and mailing prospectuses used for promotional
purposes, unless otherwise payable pursuant to a Plan), shareholders' reports,
notices, proxy statements and reports to regulatory agencies; insurance premiums
and certain expenses relating to insurance coverage; trade association
membership dues; brokerage and other expenses connected with the execution of
portfolio transactions; fees and expenses of its custodian, including those for
keeping books and accounts and calculating the NAV per share of a Fund; expenses
of shareholders' meetings; expenses relating to the issuance, registration and
qualification of a Fund's shares; pricing services, and any extraordinary
expenses.  Expenses attributable to a Fund are charged against a Fund assets.
General expenses of the Company are allocated among all of the funds of the
Company, including a Fund, in a manner proportionate to the net assets of each
Fund, on a transactional basis, or on such other basis as the Company's Board of
Directors deems equitable.


                             FEDERAL INCOME TAXES

     The following information supplements and should be read in conjunction
with the Prospectus section entitled "Taxes."  The Prospectus describes
generally the tax treatment of distributions by the Funds.  This section of the
SAI includes additional information concerning income taxes.

     General.  The Company intends to qualify each Fund as a regulated
     -------                                                          
investment company under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code"), as long as such qualification is in the best interest of
the Fund's shareholders.  Each Fund will be treated as a separate entity for tax
purposes and thus the provisions of the Code applicable to regulated 

                                      36
<PAGE>
 
investment companies will generally be applied to each Fund, rather than to the
Company as a whole. In addition, net capital gain, net investment income, and
operating expenses will be determined separately for each Fund. As a regulated
investment company, each Fund will not be taxed on its net investment income and
capital gains distributed to its shareholders.

     Qualification as a regulated investment company under the Code requires,
among other things, that (a) each Fund derive at least 90% of its annual gross
income from dividends, interest, certain payments with respect to securities
loans, gains from the sale or other disposition of stock or securities or
foreign currencies (to the extent such currency gains are directly related to
the regulated investment company's principal business of investing in stock or
securities) and other income (including but not limited to gains from options,
futures or forward contracts) derived with respect to its business of investing
in such stock, securities or currencies; and (b) the Fund diversify its holdings
so that, at the end of each quarter of the taxable year, (i) at least 50% of the
market value of the Fund's assets is represented by cash, government securities
and other securities limited in respect of any one issuer to an amount not
greater than 5% of the Fund's 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
obligations and the securities of other regulated investment companies), or in
two or more issuers which the Fund controls and which are determined to be
engaged in the same or similar trades or businesses.

     The Funds must also distribute or be deemed to distribute to their
shareholders at least 90% of their net investment income earned in each taxable
year.  In general, these distributions must actually or be deemed to be made in
the taxable year.  However, in certain circumstances, such distributions may be
made in the 12 months following the taxable year.  The Funds intend to pay out
substantially all of their net investment income and net realized capital gains
(if any) for each year.

     In addition, a regulated investment company must, in general, derive less
than 30% of its gross income from the sale or other disposition of securities or
options thereon held for less than three months.  However, this restriction has
been repealed with respect to a regulated investment company's taxable years
beginning after August 5, 1997.

     Excise Tax.  A 4% nondeductible excise tax will be imposed on each Fund
     ----------                                                             
(other than to the extent of its tax-exempt interest income) to the extent it
does not meet certain minimum distribution requirements by the end of each
calendar year.  Each Fund intends to actually or be deemed to distribute
substantially all of its net investment income and net capital gains by the end
of each calendar year and, thus, expects not to be subject to the excise tax.

     Taxation of Fund Investments.  Except as provided herein, gains and losses
     ----------------------------                                              
on the sale of portfolio securities by a Fund will generally be capital gains
and losses.  Such gains and losses will ordinarily be long-term capital gains
and losses if the securities have been held by the Fund for more than one year
at the time of disposition of the securities.

     Gains recognized on the disposition of a debt obligation (including tax-
exempt obligations purchased after April 30, 1993) purchased by the Fund at a
market discount 

                                      37
<PAGE>
 
(generally at a price less than its principal amount) will be treated as
ordinary income to the extent of the portion of market discount which accrued,
but was not previously recognized pursuant to an available election, during the
term the Fund held the debt obligation.

     Capital Gain Distributions.  Distributions which are designated by a Fund
     --------------------------                                               
as capital gain distributions will be taxed to shareholders as long-term capital
gain (to the extent such dividends do exceed the Fund's actual net capital gain
for the taxable year), regardless of how long a shareholder has held Fund
shares.  Such distributions will be designated as capital gain distributions in
a written notice mailed by the Fund to its shareholders not later than 60 days
after the close of the Fund's taxable year.

     The Taxpayer Relief Act of 1997 (the "1997 Act") created several new
categories of capital gains applicable to noncorporate taxpayers.  Under prior
law, noncorporate taxpayers were generally taxed at a maximum rate of 28% on net
capital gain (generally, the excess of net long-term capital gain over net
short-term capital loss).  Noncorporate taxpayers are now generally taxed at a
maximum rate of 20% on net capital gain attributable to gains realized on the
sale of property held for greater than 18 months, and a maximum rate of 28% on
net capital gain attributable to gain realized on the sale of property held for
greater than one year and not more than 18 months.  The 1997 Act retains the
treatment of short term capital gain or loss (generally, gain or loss
attributable to capital assets held for 1 year or less) and did not affect the
taxation of capital gains in the hands of corporate taxpayers.

     Under the 1997 Act, the Treasury is authorized to issue regulations for
application of the reduced capital gains tax rates to pass-through entities,
including regulated investment companies, such as the Funds.  Noncorporate
shareholders of the Funds may therefore qualify for the reduced rate of tax on
capital gain dividends paid by the Funds.

     Other Distributions.  Although dividends will be declared daily based on
     -------------------                                                     
each Fund's daily earnings, for federal income tax purposes, the Fund's earnings
and profits will be determined at the end of each taxable year and will be
allocated pro rata over the entire year.  For federal income tax purposes, only
amounts paid out of earnings and profits will qualify as dividends.  Thus, if
during a taxable year a Fund's declared dividends (as declared daily throughout
the year) exceed the Fund's net income (as determined at the end of the year),
only that portion of the year's distributions which equals the year's earnings
and profits will be deemed to have constituted a dividend.  It is expected that
each Fund's net income, on an annual basis, will equal the dividends declared
during the year.

     Disposition of Fund Shares.  A disposition of Fund shares pursuant to
     --------------------------                                           
redemption (including a redemption in-kind) or exchanges will ordinarily result
in a taxable capital gain or loss, depending on the amount received for the
shares (or are deemed to receive in the case of an exchange) and the cost of the
shares.

     If a shareholder exchanges or otherwise disposes of Fund shares within 90
days of having acquired such shares and if, as a result of having acquired those
shares, the shareholder subsequently pays a reduced sales charge on a new
purchase of shares of the Fund or a different regulated investment company, the
sales charge previously incurred acquiring the Fund's shares 

                                      38
<PAGE>
 
shall not be taken into account (to the extent such previous sales charges do
not exceed the reduction in sales charges on the new purchase) for the purpose
of determining the amount of gain or loss on the disposition, but will be
treated as having been incurred in the acquisition of such other shares. Also,
any loss realized on a redemption or exchange of shares of the Fund will be
disallowed to the extent that substantially identical shares are acquired within
the 61-day period beginning 30 days before and ending 30 days after the shares
are disposed of.

     If a shareholder receives a designated capital gain distribution (to be
treated by the shareholder as long-term capital gain) with respect to any Fund
share and such Fund share is held for six months or less, then (unless otherwise
disallowed) any loss on the sale or exchange of that Fund share will be treated
as long-term capital loss to the extent of the designated capital gain
distribution. In addition, if a shareholder holds Fund shares for six months or
less, any loss on the sale or exchange of those shares will be disallowed to the
extent of the amount of exempt-interest dividends received with respect to the
shares.  The Treasury Department is authorized to issue regulations reducing the
six months holding requirement to a period of not less than the greater of 31
days or the period between regular dividend distributions where a Fund regularly
distributes at least 90% of its net tax-exempt interest, if any.  No such
regulations had been issued as of the date of this SAI.  The loss disallowance
rules described in this paragraph do not apply to losses realized under a
periodic redemption plan.

     Federal Income Tax Rates.  As of the printing of this SAI, the maximum
     ------------------------                                              
individual tax rate applicable to ordinary income is 39.6% (marginal tax rates
may be higher for some individuals to reduce or eliminate the benefit of
exemptions and deductions); the maximum individual marginal tax rate applicable
to net capital gain is 28% (however, see "Capital Gain Distributions" above);
and the maximum corporate tax rate applicable to ordinary income and net capital
gain is 35% (marginal tax rates may be higher for some corporations to reduce or
eliminate the benefit of lower marginal income tax rates).  Naturally, the
amount of tax payable by an individual or corporation will be affected by a
combination of tax laws covering, for example, deductions, credits, deferrals,
exemptions, sources of income and other matters.

     Backup Withholding.  The Company may be required to withhold, subject to
     ------------------                                                      
certain exemptions, at a rate of 31% ("backup withholding") on dividends,
capital gain distributions, and redemption proceeds (including proceeds from
exchanges and redemptions in-kind) paid or credited to an individual Fund
shareholder, unless the shareholder certifies that the Taxpayer Identification
Number ("TIN") provided is correct and that the shareholder is not subject to
backup withholding, or the IRS notifies the Company that the shareholder's TIN
is incorrect or that the shareholder is subject to backup withholding.  Such tax
withheld does not constitute any additional tax imposed on the shareholder, and
may be claimed as a credit or refund on the shareholder's federal income tax
return.  An investor must provide a valid TIN upon opening or reopening an
account.  Failure to furnish a valid TIN to the Company could subject the
investor to penalties imposed by the IRS.  Foreign shareholders of the Funds
(described below) are generally not subject to backup withholding.

     Foreign Shareholders.  Under the Code, distributions of net investment
     --------------------                                                  
income by a Fund to a nonresident alien individual, foreign trust (i.e., trust
which a U.S. court is able to exercise 

                                      39
<PAGE>
 
primary supervision over administration of that trust and one or more U.S.
persons have authority to control substantial decisions of that trust), foreign
estate (i.e., the income of which is not subject to U.S. tax regardless of
source), foreign corporation, or foreign partnership (a "foreign shareholder")
will be subject to U.S. income tax withholding (at a rate of 30% or a lower
treaty rate, if applicable). Withholding will not apply if a dividend
distribution paid by a Fund to a foreign shareholder is "effectively connected"
with a U.S. trade or business (or, if an income tax treaty applies, is
attributable to a U.S. permanent establishment of the foreign shareholder), in
which case the reporting and withholding requirements applicable to U.S.
residents will apply. Distributions of net capital gain are generally not
subject to U.S. income tax withholding.

     New Regulations.  On October 6, 1997, the Treasury Department issued new
     ---------------                                                         
regulations (the "New Regulations") which make certain modifications to the
backup withholding, U.S. income tax withholding and information reporting rules
applicable to foreign shareholders.  The New Regulations will generally be
effective for payments made after December 31, 1998, subject to certain
transition rules.  Among other things, the New Regulations will permit the Funds
to estimate the portion of their distributions qualifying as capital gain
distributions for purposes of determining the portion of such distributions paid
to foreign shareholders which will be subject to U.S. income tax withholding.
Prospective investors are urged to consult their own tax advisors regarding the
New Regulations.

     Tax-Deferred Plans.  The shares of the Funds (except the National Tax-Free
     ------------------                                                        
Money Market Mutual Fund) are available for a variety of tax-deferred retirement
and other plans, including Individual Retirement Accounts ("IRA"), Simplified
Employee Pension Plans ("SEP-IRA"), Savings Incentive Match Plans for Employees
("SIMPLE plans"), Roth IRAs, and Education IRAs, which permit investors to defer
some of their income from taxes.  Investors should contact their selling agents
for details concerning retirement plans.

     Special Tax Considerations for National Tax Free Money Market Mutual Fund.
     -------------------------------------------------------------------------  
The National Tax-Free Money Market Mutual Fund intends that at least 50% of the
value of its  total assets at the close of each quarter of its taxable years
will consist of obligations, the interest on which is exempt from federal income
tax, so that it will qualify under the Code to pay "exempt-interest dividends."
The portion of total dividends paid by the National Tax-Free Money Market Mutual
Fund with respect to any taxable year that constitutes exempt-interest dividends
will be the same for all shareholders receiving dividends during such year.
Long-term and/or short-term capital gain distributions will not constitute
exempt-interest dividends and will be taxed as capital gain or ordinary income
dividends, respectively.  The exemption of interest income derived from
investments in tax-exempt obligations for federal income tax purposes may not
result in a similar exemption under the laws of a particular state or local
taxing authority.

     Not later than 60 days after the close of its taxable year, the National
Tax-Free Money Market Mutual Fund will notify its shareholders of the portion of
the dividends paid with respect to such taxable year which constitutes exempt-
interest dividends.  The aggregate amount of dividends so designated cannot
exceed the excess of the amount of interest excludable from gross income under
Section 103 of the Code received by the Fund during the taxable year over any

                                      40
<PAGE>
 
amounts disallowed as deductions under Sections 265 and 171(a)(2) of the Code.
Interest on indebtedness incurred to purchase or carry shares of the National
Tax-Free Money Market Mutual Fund will not be deductible to the extent that the
Fund's distributions are exempt from federal income tax.

     In addition, the federal alternative minimum tax ("AMT") rules ensure that
at least a minimum amount of tax is paid by taxpayers who obtain significant
benefit from certain tax deductions and exemptions.  Some of these deductions
and exemptions have been designated "tax preference items" which must be added
back to taxable income for purposes of calculating AMT.  Among the tax
preference items is tax-exempt interest from "private activity bonds" issued
after August 7, 1986.  To the extent that the National Tax-Free Money Market
Mutual Fund invests in private activity bonds, its shareholders who pay AMT will
be required to report that portion of Fund dividends attributable to income from
the bonds as a tax preference item in determining their AMT.  Shareholders will
be notified of the tax status of distributions made by the National Tax-Free
Money Market Mutual Fund.  Persons who may be "substantial users" (or "related
persons" of substantial users) of facilities financed by private activity bonds
should consult their tax advisors before purchasing National Tax-Free Money
Market Mutual Fund shares.  Furthermore, shareholders will not be permitted to
deduct any of their share of the Fund's expenses in computing their AMT.  With
respect to a corporate shareholder of the National Tax-Free Money Market Mutual
Fund, exempt-interest dividends paid by the Fund is included in the corporate
shareholder's "adjusted current earnings" as part of its AMT calculation, and
may also affect its federal "environmental tax" liability.  As of the printing
of this SAI, individuals are subject to an AMT at a maximum rate of 28% and
corporations at a maximum rate of 20%.  Shareholders with questions or concerns
about AMT should consult their own tax advisors.

     Shares of the National Tax-Free Money Market Mutual Fund would not be
suitable for tax-exempt institutions and may not be suitable for retirement
plans qualified under Section 401 of the Code, H.R. 10 plans and IRAs since such
plans and accounts are generally tax-exempt and, therefore, would not benefit
from the exempt status of dividends from the Fund.  Such dividends would be
ultimately taxable to the beneficiaries when distributed to them.

     Investors are advised to consult their tax advisors concerning the
application of state and local taxes, which may have different consequences from
those under federal income tax law.

     Other Matters.  Investors should be aware that the investments to be made
     -------------                                                            
by a Fund may involve sophisticated tax rules that may result in income or gain
recognition by the Fund without corresponding current cash receipts.  Although
the Funds will seek to avoid significant noncash income, such noncash income
could be recognized by a Fund, in which case the Fund may distribute cash
derived from other sources in order to meet the minimum distribution
requirements described above.

     The foregoing discussion and the discussions in the Prospectus applicable
to each shareholder address only some of the federal income tax considerations
generally affecting investments in a Fund.  Each investor is urged to consult
his or her tax advisor regarding specific questions as to federal, state, local
and foreign taxes.

                                      41

                                 CAPITAL STOCK

     The Funds are four of the funds in the Stagecoach Family of Funds. The
Company was organized as a Maryland corporation on September 9, 1991, and
currently offers shares of over thirty funds.

     Most of  the Company's funds are authorized to issue multiple classes of
shares, one class generally subject to a front-end sales charge and, in some
cases, classes subject to a contingent-deferred sales charge, that are offered
to retail investors.  Certain of the Company's funds also are authorized to
issue other classes of shares, which are sold primarily to institutional
investors.  Each class of shares in a fund represents an equal, proportionate
interest in a fund with other shares of the same class.  Shareholders of each
class bear their pro rata portion of the fund's operating expenses, except for
certain class-specific expenses (e.g., any state securities registration fees,
shareholder servicing fees or distribution fees that may be paid under Rule 12b-
1) that are allocated to a particular class.  Please contact Stagecoach
Shareholder Services at 1-800-222-8222 if you would like additional information
about other funds or classes of shares offered.

     With respect to matters that affect one class but not another, shareholders
vote as a class; for example, the approval of a Plan.  Subject to the foregoing,
all shares of a Fund have equal voting rights and will be voted in the
aggregate, and not by series, except where voting by a series is required by law
or where the matter involved only affects one series.  For example, a change in
a Fund's fundamental investment policy affects only one Series and would be
voted upon only by shareholders of the Fund involved.  Additionally, approval of
an advisory contract since it affects only one Fund, is a matter to be
determined separately by each Series.  Approval by the shareholders of one
Series is effective as to that Series whether or not sufficient votes are
received from the shareholders of the other Series to approve the proposal as to
those Series.

     As used in the Prospectus and in this SAI, the term "majority" when
referring to approvals to be obtained from shareholders of a Class of a Fund,
means the vote of the lesser of (i) 67% of the shares of such class of the Fund
represented at a meeting if the holders of more than 50% of the outstanding
shares of such Class Fund are present in person or by proxy, or (ii) more than
50% of the outstanding shares of such Class of the Fund.  The term "majority,"
when referring to the approvals to be obtained from shareholders of the Company
as a whole, means the vote of the lesser of (i) 67% of the Company's shares
represented at a meeting if the holders of more than 50% of the Company's
outstanding shares are present in person or by proxy, or (ii) more than 50% of
the Company's outstanding shares.

     Shareholders are entitled to one vote for each full share held and
fractional votes for fractional shares held.  Shareholders are not entitled to
any preemptive rights.  All shares, when issued, will be fully paid and non-
assessable by the Company.

     The Company may dispense with an annual meeting of shareholders in any year
in which it is not required to elect directors under the 1940 Act.

     Each share of a class of a Fund represents an equal proportional interest
in the Fund with each other share in the same class and is entitled to such
dividends and distributions out of the 

                                      42

income earned on the assets belonging to the Fund as are declared in the
discretion of the Directors. In the event of the liquidation or dissolution of
the Company, shareholders of a Fund or class are entitled to receive the assets
attributable to the Fund or class that are available for distribution, and a
distribution of any general assets not attributable to a particular investment
portfolio that are available for distribution in such manner and on such basis
as the Directors in their sole discretion may determine.

     Set forth below as of October 31, 1997 is the name, address and share
ownership of each person known by the Company to have beneficial or record
ownership of 5% or more of a class of each Fund or 5% or more of the voting
securities of each Fund as a whole.

                                 SAI APPENDIX

     The following is a description of the ratings given by Moody's and S&P to
corporate and municipal bonds, municipal notes, and corporate and municipal
commercial paper.

Corporate and Municipal Bonds
- -----------------------------

     Moody's:  The four highest ratings for corporate and municipal bonds are
"Aaa," "Aa," "A" and "Baa."  Bonds rated "Aaa" are judged to be of the "best
quality" and carry the smallest amount of investment risk.  Bonds rated "Aa" are
of "high quality by all standards," but margins of protection or other elements
make long-term risks appear somewhat greater than "Aaa" rated bonds.  Bonds
rated "A" possess many favorable investment attributes and are considered to be
upper medium grade obligations.  Bonds rated "Baa" are considered to be medium
grade obligations; interest payments and principal security appear adequate for
the present, but certain protective elements may be lacking or may be
characteristically unreliable over any great length of time.  Such bonds have
speculative characteristics as well.  Moody's applies numerical modifiers:  1, 2
and 3 in each rating category from "Aa" through "Baa" in its rating system.  The
modifier 1 indicates that the security ranks in the higher end of its category;
the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that
the issue ranks in the lower end.

     S&P:  The four highest ratings for corporate and municipal bonds are "AAA,"
"AA," "A" and "BBB."  Bonds rated "AAA" have the highest ratings assigned by S&P
and have an extremely strong capacity to pay interest and repay principal.
Bonds rated "AA" have a "very strong capacity to pay interest and repay
principal" and differ "from the highest rated issued only in small degree."
Bonds rated "A" have a "strong capacity" to pay interest and repay principal,
but are "somewhat more susceptible" to adverse effects of changes in economic
conditions or other circumstances than bonds in higher rated categories.  Bonds
rated "BBB" are regarded as having an "adequate capacity" to pay interest and
repay principal, but changes in economic conditions or other circumstances are
more likely to lead to a "weakened capacity" to make such repayments.  The
ratings from "AA" to "BBB" may be modified by the addition of a plus or minus
sign to show relative standing within the category.

Municipal Notes
- ---------------

     Moody's:  The highest ratings for state and municipal short-term
obligations are "MIG 1," "MIG 2," and "MIG 3" (or "VMIG 1," "VMIG 2" and "VMIG
3" in the case of an issue having a variable rate demand feature).  Notes rated
"MIG 1" or "VMIG 1" are judged to be of the "best quality."  Notes rated "MIG 2"
or "VMIG 2" are of "high quality," with margins of protections "ample although
not as large as in the preceding group."  Notes rated "MIG 3" or "VMIG 3" are of
"favorable quality," with all security elements accounted for, but lacking the
strength of the preceding grades.

     S&P:  The "SP-1" rating reflects a "very strong or strong capacity to pay
principal and interest."  Notes issued with "overwhelming safety
characteristics" will be rated "SP-1+."  The "SP-2" rating reflects a
"satisfactory capacity" to pay principal and interest.

                                      A-1
<PAGE>
 
Corporate and Municipal Commercial Paper
- ----------------------------------------

     Moody's:  The highest rating for corporate and municipal commercial paper
is "P-1" (Prime-1).  Issuers rated "P-1" have a "superior capacity for repayment
of short-term promissory obligations."  Issuers rated "P-2" (Prime-2) "have a
strong capacity for repayment of short-term promissory obligations," but
earnings trends, while sound, will be subject to more variation.

     S&P:  The "A-1" rating for corporate and municipal commercial paper
indicates that the "degree of safety regarding timely payment is either
overwhelming or very strong."  Commercial paper with "overwhelming safety
characteristics" will be rated "A-1+."  Commercial paper with a strong capacity
for timely payments on issues will be rated "A-2."

Corporate Notes
- ---------------

     S&P:  The two highest ratings for corporate notes are "SP-1" and "SP-2."
The "SP-1" rating reflects a "very strong or strong capacity to pay principal
and interest."  Notes issued with "overwhelming safety characteristics" will be
rated "SP-1+."  The "SP-2" rating reflects a "satisfactory capacity" to pay
principal and interest.

                                    GENERAL

     The Overland Express Sweep Fund was originally organized on October 1,
1991, as the Overland Sweep Fund (the "predecessor portfolio") of Overland
Express Funds, Inc. ("Overland"), another open-end management investment company
advised by Wells Fargo Bank. On July 23, 1997, the Boards of the Directors of
the Company and Overland approved an Agreement and Plan of Consolidation
providing for, among other things, the transfer of the assets and stated
liabilities of the predecessor Overland portfolio to the Overland Express Sweep
Fund. Prior to December 12, 1997, the effective date of the Consolidation, the
Fund had only minimal assets and liabilities. Prior to the Consolidation, the
predecessor portfolio pursued its investment objective by investing all of its
assets in the Cash Investment Trust Master Portfolio (the "Master Portfolio") of
Master Investment Trust ("MIT"). The Fund now invests directly in a portfolio of
securities and does not invest in a corresponding Master Portfolio.

                            INVESTMENT RESTRICTIONS


     Fundamental Investment Policies
     -------------------------------

     The Fund has adopted the following investment restrictions, all of which
are fundamental policies; that is, they may not be changed without approval by a
vote of the holders of a majority (defined in the Investment Company Act of
1940, as amended (the "1940 Act")) of the outstanding voting securities of the
Fund.

The Overland Express Sweep Fund may not:

     (1)  purchase the securities of issuers conducting their principal business
activity in the same industry if, immediately after the purchase and as a result
thereof, the value of the Fund's investments in that industry would exceed 25%
of the current value of its respective total assets, provided that there is no
limitation with respect to investments in (i) obligations of the United States
Government, its agencies or instrumentalities, and (ii) obligations of domestic
banks (for the purpose of this restriction, domestic bank obligations do not
include obligations of U.S. branches of foreign banks or obligations of foreign
branches of U.S.  banks);

     (2)  purchase or sell real estate or real estate limited partnership
interests (other than money market securities secured by real estate or
interests therein or securities issued by companies that invest in real estate
or interests therein), commodities or commodity contracts;

     (3)  purchase securities on margin (except for short-term credits necessary
for the clearance of transactions) or make short sales of securities;

     (4)  underwrite securities of other issuers, except to the extent that the
purchase of permitted investments directly from the issuer thereof or from an
underwriter for an issuer 

                                       1
<PAGE>
 
and the later disposition of such securities in accordance with the Fund's
investment program may be deemed to be an underwriting;

     (5)  make investments for the purpose of exercising control or management;

     (6)  issue senior securities, except that the Fund may borrow from banks up
to 10% of the current value of their respective net assets for temporary
purposes only in order to meet redemptions, and these borrowings may be secured
by the pledge of up to 10% of the current value of their respective net assets
(but investments may not be purchased while any such borrowing in excess of 5%
of their respective net assets exists);

     (7)  write, purchase or sell puts, calls, warrants or options or any
combination thereof, except that the Fund may purchase securities with put
rights in order to maintain liquidity; nor

     (8)  make loans of portfolio securities or other assets, except that loans
for purposes of this restriction will not include the purchase of fixed time
deposits, repurchase agreements, commercial paper and other short-term
obligations, and other types of debt instruments commonly sold in a public or
private offering.

     Non-Fundamental Investment Policies
     -----------------------------------

     The Fund has adopted the following non-fundamental policies which may be
changed by a majority vote of the Board of Directors of the Company at any time
and without approval of the Fund's shareholders.

     (1)  The Fund may invest in shares of other open-end management investment
companies, subject to the limitations of Section 12(d)(1) of the 1940 Act.
Under the 1940 Act, the Fund's investment in such securities currently is
limited to , subject to certain exceptions, (i) 3% of the total voting stock of
any one investment company, (ii) 5% of the Fund's net assets with respect to any
one investment company, and (iii) 10% of the Fund's net assets in the aggregate.
Other investment companies in which the Fund invests can be expected to charge
fees for operating expenses, such as investment advisory and administration
fees, that would be in addition to those charged by the Fund.

     (2)  The Fund may not invest more than 10% of the Fund's net assets in
illiquid securities.  For this purpose, illiquid securities include, among
others, (a) securities that are illiquid by virtue of the absence of a readily
available market or legal or contractual restrictions on resale, (b) fixed time
deposits that are subject to withdrawal penalties and that have maturities of
more than seven days, and (c) repurchase agreements not terminable within seven
days.

     (3)  The Fund may invest up to 25% of its net assets in securities of
foreign governmental and foreign private issuers that are denominated in and pay
interest in U.S. dollars.

                                       2
<PAGE>
 
     (4)  The Fund may lend securities from its portfolio to brokers, dealers
and financial institutions, in amounts not to exceed (in the aggregate) one-
third of the Fund's total assets.  Any such loans of portfolio securities will
be fully collateralized based on values that are marked to market daily.  The
Fund will not enter into any portfolio security lending arrangement having a
duration of longer than one year.

                  ADDITIONAL PERMITTED INVESTMENT ACTIVITIES


     Set forth below are descriptions of certain investments and additional
investment policies for the Fund.
     
     Floating- and Variable-Rate Instruments
     ---------------------------------------

     Certain of the debt instruments in which the Fund may invest may bear
interest rates that are periodically adjusted at specified intervals or whenever
a benchmark rate or index changes.  These adjustments generally limit the
increase or decrease in the amount of interest received on the debt instruments.
The floating- and variable-rate instruments that the Fund may purchase include
certificates of participation in pools of floating- and variable-rate
instruments.  Floating- and variable-rate instruments are subject to interest
rate risk and credit risk.

     Foreign Obligations
     -------------------

     The Fund may invest a portion of its assets (no more than 5%) in
obligations of foreign branches of U.S. banks or U.S. branches of foreign banks
that are denominated in and pay interest in U.S. dollars.  Investments in
foreign obligations involve certain considerations that are not typically
associated with investing in domestic obligations.  There may be less publicly
available information about a foreign issuer than about a domestic issuer.
Foreign issuers also are not subject to the same accounting, auditing and
financial reporting standards or governmental supervision as domestic issuers.
In addition, with respect to certain foreign countries, taxes may be withheld at
the source under foreign income tax laws, and there is a possibility of
expropriation or confiscatory taxation, political or social instability or
diplomatic developments that could adversely affect investments in, the
liquidity of, and the ability to enforce contractual obligations with respect
to, securities of issuers located in those countries.

     Illiquid Securities
     -------------------

     The Fund may invest in securities not registered under the Securities Act
of 1933 and other securities subject to legal or other restrictions on resale.
Because such securities may be less liquid than other investments, they may be
difficult to sell promptly at an acceptable price.  Delay or difficulty in
selling securities may result in a loss or be costly to the Fund.

                                       3
<PAGE>
 
     Letters of Credit
     -----------------

     Certain of the debt obligations, certificates of participation, commercial
paper and other short-term obligations in which the Fund is permitted to invest
may be backed by an unconditional and irrevocable letter of credit of a bank,
savings and loan association or insurance company that assumes the obligation
for payment of principal and interest in the event of default by the issuer.
Letter of credit-backed investments must, in the opinion of Wells Fargo Bank, be
of investment quality comparable to other permitted high-quality investments of
the Fund.

     Money Market Instruments
     ------------------------

     Money market instruments consist of:  (a) short-term securities issued or
guaranteed by the U.S. Government, its agencies or instrumentalities (including
government-sponsored enterprises) (U.S. Government obligations"); (b) negotiable
certificates of deposit, bankers' acceptances and fixed time deposits and other
short-term obligations of domestic banks (including foreign branches) that have
more than $1 billion in total assets at the time of the investment and are
members of the Federal Reserve System or are examined by the Comptroller of the
Currency or whose deposits are insured by the FDIC; (c) commercial paper rated
at the date of purchase "Prime-1" by Moody's or "A-1+" or "A-1" by S&P, or, if
unrated, by comparable qualify as determined by Wells Fargo Bank; (d) certain
repurchase agreements; and (e) short-term U.S. dollar-denominated obligations of
foreign banks (including U.S. branches) that at the time of investment; (i) have
more than $10 billion, or the equivalent in other currencies, in total assets;
(ii)  are among the largest foreign banks in the world as determined on the
basis of assets; and (iii) have branches or agencies in the United States.

     Other Investment Companies
     --------------------------

     The Fund may invest in shares of other open-end management investment
companies, up to the limits prescribed in Section 12(d) of the 1940 Act.  Under
the 1940 Act, the Fund's investment in such securities currently is limited to,
subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5% of the Fund's net assets with respect to any one
investment company and (iii) 10% of the Fund's net assets in aggregate.  Other
investment companies in which the Fund invest can be expected to charge fees for
operating expenses such as investment advisory and administration fees, that
would be in addition to those charged by the Fund.

     Repurchase Agreements
     ---------------------

     The Fund may enter into repurchase agreements wherein the seller of a
security to the Fund agrees to repurchase that security from the Fund at a
mutually agreed-upon time and price.  The period of maturity is usually quite
short, often overnight or a few days, although it may extend over a number of
months. The Fund may enter into repurchase agreements only with respect to U.S.
Government obligations and other securities that are permissible investments for
the Fund.  All repurchase agreements will be fully 

                                       4
<PAGE>
 
collateralized at 102% based on values that are marked to market daily. The
maturities of the underlying securities in a repurchase agreement transaction
may be greater than twelve months. However, the term of any repurchase agreement
on behalf of the Fund will always be less than twelve months. If the seller
defaults and the value of the underlying securities has declined, the Fund may
incur a loss. In addition, if bankruptcy proceedings are commenced with respect
to the seller of the security, the Fund's disposition of the security may be
delayed or limited.

     The Fund may not enter into a repurchase agreement with a maturity of more
than seven days if, as a result, more than 10% of the market value of it's total
net assets would be invested in repurchase agreements with maturities of more
than seven days, restricted securities and/or illiquid securities.  The Fund
will enter into repurchase agreements only with primary broker/dealers and
commercial banks that meet guidelines established by the Board of Directors of
the Company and that are not affiliated with Wells Fargo Bank.  The Fund,
subject to the conditions described above, may participate in pooled repurchase
agreement transactions with other funds advised by Wells Fargo Bank.

     Unrated Investments
     -------------------

     The Fund may purchase instruments that are not rated if, in the opinion of
Wells Fargo Bank as investment adviser, such obligations are of comparable
quality to other high-quality investments that are permitted to be purchased by
the Fund.  After purchase by the Fund, a security may cease to be rated or its
rating may be reduced below the minimum required for purchase by the Fund.
Neither event requires an immediate sale of such security by the Fund.  To the
extent the ratings given by Moody's Investors Service ("Moody's") or Standard
and Poor's Rating Group ("S&P") may change as a result of changes in such
organizations or their rating systems, the Fund will attempt to use comparable
ratings as standards for investments in accordance with the investment policies
contained in the Prospectus and in this SAI.  The ratings of Moody's and S&P are
more fully described in the Appendix to this SAI.

     U.S. Government Obligations
     ---------------------------

     U.S. Government obligations include securities issued or guaranteed by the
U.S. Government, its agencies or instrumentalities.  Payment of principal and
interest on U.S. Government obligations may be backed by the full faith and
credit of the United States, as with Treasury bills, or may be backed solely by
the issuing or guaranteeing agency or instrumentality itself.  In the latter
case investors must look principally to the agency or instrumentality itself.
In the latter case investors must look principally to the agency or
instrumentality issuing or guaranteeing the obligation for ultimate repayment,
which agency or instrumentality may be privately owned.  There can be no
assurance that the U.S. Government will provide financial support to its
agencies or instrumentalities where it is not obligated to do so.  In addition,
U.S. Government obligations are subject to fluctuations in market value due to
fluctuations in market interest rates.  As a general matter, the value of debt
instruments, including U.S. Government obligations, declines when market
increase rates increase and rises when market interest rates decrease.  Certain
types of U.S. 

                                       5
<PAGE>
 
Government obligations are subject to fluctuations in yield, duration or value
due to their structure or contract terms.

                                 RISK FACTORS

     Investments in the Fund are not bank deposits or obligations of Wells Fargo
Bank, are not insured by the FDIC and are not insured or guaranteed against loss
of principal.  Therefore, you should be willing to accept some risk with money
you invest in the Fund.  Although the Fund seeks to maintain a stable net asset
value of $1.00 per share, there is no assurance that it will be able to do so.
As with all mutual funds, there is no assurance that the Fund will achieve its
investment objective.

     The Fund, under the 1940 Act, must comply with certain investment criteria
designed to provide liquidity, reduce risk and allow the Fund to maintain a
stable net asset value of $1.00 per share.  The Fund seeks to reduce risk by
investing in securities of various issuers and will comply with 1940 Act and
Internal Revenue Code of 1986 (the "Code") diversification requirements.

     Since its inception, the Fund has emphasized safety of principal and high
credit quality.  In particular, the internal investment policies of the Fund's
investment policies of the Fund's investment adviser, Wells Fargo, have always
prohibited the purchase of many types of floating rate instruments commonly
referred to as "derivatives" that are considered potentially volatile.  The
following types of derivative securities ARE NOT permitted investments for the
Fund:

          .    capped floaters (on which interest is not paid when market rates 
               move above a certain level);

          .    leveraged floaters (whose interest-rate reset provisions are 
               based on a formula that magnifies changes in interest rates);

          .    range floaters (which do not pay any interest if market interest 
               rates move outside of a specified range);

          .    dual index floaters (whose interest rate reset provisions are 
               tied to more than one index so that a change in the relationship
               between these indices may result in the value of the instrument
               falling below face value); and

          .    inverse floaters (which reset in the opposite direction of their
               index).

     Additionally, the Fund may not invest in securities whose interest rate
reset provisions are tied to an index that materially lags short-term interest
rates, such as Cost of Funds Index floaters.  The Fund may only invest in
floating rate instruments that bear 

                                       6
<PAGE>
 
interest at a rate that resets quarterly or more frequently, and which resets
based on changes in standard money market rate indices such as U.S. Treasury
bills, London Interbank Offered Rate, the prime rate, published commercial paper
rates, federal funds rates, Public Securities Associates floaters or JJ Kenney
index floaters.

                                  MANAGEMENT

     As of January 1, 1998, Peter G. Gordon will replace Robert M. Joses on the
Board of Directors of the Wells Fargo Fund Complex.

     Directors of the Company are compensated annually by the Company and by all
the registrants in each fund complex they serve as indicated above and also are
reimbursed for all out-of-pocket expenses relating to attendance at board
meetings. The Company, Stagecoach Trust and Life & Annuity Trust are considered
to be members of the same fund complex as such term is defined in Form N-1A
under the 1940 Act (the "Wells Fargo Fund Complex"). Overland Express Funds,
Inc. and Master Investment Trust, two investment companies previously advised by
Wells Fargo Bank, were part of the Wells Fargo Fund Complex prior to December
15, 1997. These companies are no longer part of the Wells Fargo Fund Complex.
MasterWorks Funds Inc., Master Investment Portfolio, and Managed Series
Investment Trust together form a separate fund complex (the "BGFA Fund
Complex"). Each of the Directors and Officers of the Company serves in the
identical capacity as directors and officers or as trustees and/or officers of
each registered open-end management investment company in both the Wells Fargo
and BGFA Fund Complexes, except for Joseph N. Hankin, who only serves the
aforementioned members of the Wells Fargo Fund Complex. The Directors are
compensated by other companies and trusts within a fund complex for their
services as directors/trustees to such companies and trusts. Currently the
Directors do not receive any retirement benefits or deferred compensation from
the Company or any other member of each fund complex.

     As of the date of this SAI, Directors and Officers of the Company as a
group beneficially owned less than 1% of the outstanding shares of the Company.

     INVESTMENT ADVISER.  Wells Fargo Bank provides investment advisory services
to the Fund.  As investment adviser, Wells Fargo Bank furnishes investment
guidance and policy direction in connection with the daily portfolio management
of the Fund. Wells Fargo Bank furnishes to the Company's Board of Directors
periodic reports on the investment strategy and performance of the Fund.  Wells
Fargo Bank provides the Fund with, among other things, money market security and
fixed-income research, analysis and statistical and economic data and
information concerning interest rate and securities markets trends, portfolio
composition, and credit conditions.

     As compensation for its advisory services, Wells Fargo Bank is entitled to
receive a monthly fee at the annual rate of 0.25% of the Fund's average daily
net assets.

     For the six-month period ended March 31, 1997, the Fund paid to Wells Fargo
Bank advisory fees of $____________ of which $___________ were waived by Wells
Fargo Bank.  As the Fund did not commence operations until December 12, 1997,
the fee amount represents fees paid by the predecessor portfolio.

     Prior to the Consolidation, the predecessor portfolio invested all of its
assets in the Master Portfolio of MIT and did not retain an investment adviser.
Wells Fargo Bank served as investment adviser to the Master Portfolio in which
the predecessor portfolio invested and was entitled to receive a monthly fee at
the annual rate of 0.25% of the Master Portfolio's average daily net assets.
For the years ended December 31, 1994, 1995 and 1996, the Master Portfolio paid
to Wells Fargo Bank the following advisory fees and Wells Fargo Bank waived the
indicated amounts:

     General.  The Fund's Advisory Contract will continue in effect for more 
     -------
than two years from the effective date provided the continuance is approved
annually (i) by the holders of a majority of the Fund's outstanding voting
securities or by the Company's Board of Directors and (ii) by a majority of the
Directors of the Company who are not parties to the Advisory Contract or
"interested persons" (as defined in the 1940 Act) of any such party. The
Advisory Contract may be terminated on 60 days' written notice by either party
and will terminate automatically if assigned.

     ADMINISTRATOR AND CO-ADMINISTRATOR.  The Company has retained Wells Fargo
Bank as Administrator and Stephens as Co-Administrator on behalf of the Fund.
Under the respective Administration and Co-Administration Agreements among Wells
Fargo Bank, Stephens and the Company, Wells Fargo Bank and Stephens shall
provide as administration services, among other things: (i) general supervision
of the Fund's operations, including coordination of the services performed by
the Fund's investment adviser, transfer agent, custodian, shareholder servicing
agent(s), independent auditors and legal counsel, regulatory compliance,
including the compilation of information for documents such as reports to, and
filings with, the SEC and state securities commissions; and preparation of proxy
statements and shareholder reports for the Fund; and (ii) general supervision
relative to the compilation of data required for the preparation of periodic
reports distributed to the Company's officers and Board of Directors. Wells
Fargo Bank and Stephens also furnish office space and certain facilities
required for conducting the Fund's business together with ordinary clerical and
bookkeeping services. Stephens pays the compensation of the Company's Directors,
officers and employees who are affiliated with Stephens. The Administrator and
Co-Administrator are entitled to receive a monthly fee of 0.04% and 0.02%,
respectively, of the average daily net assets of the Fund.

     For the period indicated below, the Fund paid the dollar amounts to Wells
Fargo Bank and Stephens for administration and co-administration fees indicated
below.  As the Fund did not commence operations until December 12, 1997, the fee
amounts represent fees paid by the predecessor portfolio:

     Prior to the Consolidation, Wells Fargo Bank and Stephens served as
Administrator and Co-Administrator, respectively, to the Overland predecessor
portfolio under substantially similar terms as those described above.

     Prior to February 1, 1997, Stephens served as the sole Administrator and
performed substantially the same services now provided by Stephens and Wells
Fargo Bank.  Stephens was entitled to receive for its services a fee, payable
monthly, at the annual rate  of 0.05% of the Fund's average daily net assets.

     For the periods indicated below, the predecessor portfolio paid the
following dollar amounts to Stephens for administration fees:

</TABLE>

     SPONSOR AND DISTRIBUTOR.  Stephens (the "Distributor"), located at 111
Center Street, Little Rock, Arkansas 72201, serves as sponsor and distributor
for the Fund. The Fund has adopted a distribution plan (a "Plan") under Section
12(b) of the 1940 Act and Rule 12b-1 thereunder (the "Rule") for its shares. The
Plan was adopted by the Company's Board of Directors, including a majority of
the Directors who were not "interested persons" (as defined in the 1940 Act) of
the Fund and who had no direct or indirect financial interest in the operation
of the Plan or in any agreement related to the Plan (the "Non-Interested
Directors").

     Under the Plan and pursuant to the Distribution Agreement, the Fund may pay
Stephens, as compensation for distribution-related services or as reimbursement
for distribution-related expenses, a monthly fee at the annual rate of up to
0.30% of the Fund's average daily net assets attributable to its shares.

     The actual fee payable to the Distributor is determined, within such
limits, from time to time by mutual agreement between the Company and the
Distributor and will not exceed the maximum sales charges payable by mutual
funds sold by members of the National Association of Securities Dealers, Inc.
("NASD") under the Conduct Rules of the NASD. The Distributor may enter into
selling agreements with one or more selling agents (which may include Wells
Fargo Bank and its affiliates) under which such agents may receive compensation
for distribution-related services from the Distributor, including, but not
limited to, commissions or other payments to such agents based on the average
daily net assets of Fund shares attributable to their customers. The Distributor
may retain any portion of the total distribution fee payable thereunder to
compensate it for distribution-related services provided by it or to reimburse
it for other distribution-related expenses.

     For the six-month period ended March 31, 1997, the Fund's Distributor
received $_________ in compensation for distribution-related services on behalf
of the Fund's shares.  As the Fund did not commence operations until December
12, 1997, the fee amount represents fees paid by the predecessor portfolio.

                                      11
<PAGE>
 
     Prior to the Consolidation, the predecessor portfolio had adopted a
Distribution Plan on behalf of its shares providing for payment to the
Distributor of up to 0.55% of the predecessor portfolio's average daily net
assets. For the year ended December 31, 1996, the predecessor portfolio's
Distributor received $7,290,299 as compensation for distribution-related
services or as reimbursement for distribution-related expenses under the
predecessor portfolio's Plan.

     General.  The Plan will continue in effect from year to year if such
     -------                                                             
continuance is approved by a majority vote of both the Directors of the Company
and the Non-Interested Directors. Any Distribution Agreement related to the Plan
also must be approved by such vote of the Directors and the Non-Interested
Directors. Such Agreement will terminate automatically if assigned, and may be
terminated at any time, without payment of any penalty, by a vote of a majority
of the outstanding voting securities of the Fund's shares or by vote of a
majority of the Non-Interested Directors on not more than 60 days' written
notice. The Plan may not be amended to increase materially the amounts payable
thereunder without the approval of a majority of the outstanding voting
securities of the Fund, and no material amendment to the Plan may be made except
by a majority of both the Directors of the Company and the Non-Interested
Directors.

     The Plan requires that the Treasurer of the Company shall provide to the
Directors, and the Directors shall review, at least quarterly, a written report
of the amounts expended (and purposes therefor) under the Plan.  The Rule also
requires that the selection and nomination of Directors who are not "interested
persons" of the Company be made by such disinterested Directors.

     Wells Fargo Bank, an interested person (as that term is defined in Section
2(a)(19) of the 1940 Act) of the Company, acts as a selling agent for the Fund's
Class A shares pursuant to selling agreements with Stephens authorized under the
Plan. As a selling agent, Wells Fargo Bank has an indirect financial interest in
the operation of the Plan. The Board of Directors has concluded that the Plan is
reasonably likely to benefit the Fund and its shareholders because the Plan
authorizes the relationships with selling agents, including Wells Fargo Bank,
that have previously developed distribution channels and relationships with the
customers that the Fund's shares are designed to serve. These relationships and
distribution channels are believed by the Board to provide potential for
increased Fund assets and ultimately corresponding economic efficiencies (i.e.,
lower per-share transaction costs and fixed expenses) that are generated by
increased assets under management.

     SHAREHOLDER SERVICING AGENT.  The Fund has approved a Servicing Plan and
has entered into a related Shareholder Servicing Agreement, on behalf of its
shares, with financial institutions, including Wells Fargo Bank. Under the
agreement, Shareholder Servicing Agents (including Wells Fargo Bank) agree to
perform, as agents for their customers, administrative services, with respect to
Fund shares, which include aggregating and transmitting shareholder orders for
purchases, exchanges and redemptions; maintaining shareholder accounts and
records; and providing such other related services as the Company or a
shareholder may reasonably request. For providing 

                                      12
<PAGE>
 
shareholder services, a Servicing Agent is entitled to a fee from the Fund, not
to exceed 0.30%, on an annualized basis, of the average daily net assets of the
class of shares owned of record or beneficially by the customers of the
Servicing Agent during the period for which payment is being made. The Servicing
Plan and related form of shareholder servicing agreement were approved by the
Company's Board of Directors and provide that the Fund shall not be obligated to
make any payments under such Plan or related Agreements that exceed the maximum
amounts payable under the Conduct Rules of the NASD.

     For the six-month period ended March 31, 1997, the Fund paid $_________ in
shareholder servicing fees to Wells Fargo Bank or its affiliates.  As the Fund
did not commence operations until December 12, 1997, the fee amount represents
fees paid by the predecessor portfolio.

     For the year ended December 31, 1996, the predecessor portfolio to the Fund
paid $____________ in shareholder services fees to Wells Fargo Bank or its
affiliates.

     General.  The Servicing Plan will continue in effect from year to year if
     -------                                                                  
such continuance is approved by a majority vote of the Directors of the Company,
including a majority of the Directors who are not "interested persons" (as
defined in the 1940 Act) of the Fund ("Non-Interested Directors"). Any form of
Servicing Agreement related to the Servicing Plan also must be approved by such
vote of the Directors and Non-Interested Directors. Servicing Agreements may be
terminated at any time, without payment of any penalty, by vote of a majority of
the Board of Directors, including a majority of the Non-Interested Directors. No
material amendment to the Servicing Plan and related Servicing Agreement may be
made except by a majority of both the Directors of the Company and the Non-
Interested Directors.

     The Servicing Plan requires that the Administrator shall provide to the
Directors, and the Directors shall review, at least quarterly, a written report
of the amounts expended (and purposes therefor) under the Servicing Plan.

     CUSTODIAN.  Wells Fargo Bank acts as Custodian for the Fund.  The
Custodian, among other things, maintains a custody account or accounts in the
name of the Fund, receives and delivers all assets for the Fund upon purchase
and upon sale or maturity, collects and receives all income and other payments
and distributions on account of the assets of the Fund, and pays all expenses of
the Fund.  For its services as Custodian, Wells Fargo Bank is entitled to
receive fees as follows:  a net asset charge at the annual rate of 0.0167%,
payable monthly, plus specified transaction charges.  Wells Fargo Bank also will
provide portfolio accounting services under the Custody Agreement as follows: a
monthly base fee of $2,000 plus a net asset fee at the annual rate of 0.070% of
the first $50,000,000 of the Fund's average daily net assets, 0.045% of the next
$50,000,000, and 0.020% of the average daily net assets in excess of
$100,000,000.

                                      13
<PAGE>
 
     For the six-month period ended March 31, 1997, the Fund paid $_____________
in custody fees to Wells Fargo Bank.  As the Fund did not commence operations
until December 12, 1997, the fee amount represents fees paid by the predecessor
portfolio.

     Prior to the Consolidation, Wells Fargo Bank served as Custodian to the
predecessor portfolio.  For the year ended December 31, 1996, the predecessor
portfolio did not pay any custody fees, after waivers, to Wells Fargo Bank.

     TRANSFER AND DIVIDEND DISBURSING AGENT.  Wells Fargo Bank acts as Transfer
and Dividend Disbursing Agent for the Fund.  For providing such services, Wells
Fargo Bank is entitled to receive monthly payments at the annual rate of 0.10%
of the Fund's average daily net assets of Class A shares.

     For the six-month period ended March 31, 1997, the Fund paid $__________ in
compensation for transfer and dividend disbursing agency services to Wells Fargo
Bank.  As the Fund did not commence operations until December 12, 1997, the fee
amount represents fees paid by the predecessor portfolio.

     Under a prior transfer agency agreement with the predecessor portfolio,
Wells Fargo Bank was entitled to receive a base fee and per-account fees.  For
the year ended December 31, 1996, the predecessor portfolio paid $4,637,643 in
compensation for transfer and dividend disbursing agency services to Wells Fargo
Bank.

     UNDERWRITING COMMISSIONS.  The Fund does not charge any front-end sales
loads or contingent-deferred sales charges in connection with the purchase and
redemption of its shares, and therefore pays no underwriting commissions to the
Distributor.

                           PERFORMANCE CALCULATIONS

     The Fund may advertise certain yield and total return information.
Quotations of yield and total return reflect only the performance of a
hypothetical investment in the Fund during the particular time period shown.
Yield and total return vary based on changes in the market conditions and the
level of the Fund's expenses, and no reported performance figure should be
considered an indication of performance which may be expected in the future.

     In connection with communicating its performance to current or prospective
shareholders, these figures may also be compared to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

     Performance information for the Fund may be useful in reviewing the
performance of the Fund and for providing a basis for comparison with investment
alternatives.  The yield of the Fund, however, may not be comparable to the
yields from 

                                      14
<PAGE>
 
investment alternatives because of differences in the foregoing variables and
differences in the methods used to value portfolio securities, compute expenses
and calculate yield.

     TOTAL RETURN:  The Fund may advertise certain total return information
     ------------                                                          
computed in the manner described in the Prospectus. As and to the extent
required by the SEC, an average annual compound rate of return ("T") is computed
by using the redeemable value at the end of a specified period ("ERV") of a
hypothetical initial investment ("P") over a period of years ("n") according to
the following formula: P(1+T)n=ERV. In addition, as indicated in the Prospectus,
the Fund also may, at times, calculate total return based on net asset value per
share (rather than the public offering price), in which case the figures would
not reflect the effect of any sales charges that would have been paid by an
investor, or based on the assumption that a sales charge other than the maximum
sales charge (reflecting a Volume Discount) was assessed, provided that total
return data derived pursuant to the calculation described above also are
presented.

     Performance information may be advertised for non-standardized periods,
including year-to-date and other periods less than a year for the Funds.

     YIELD CALCULATIONS:  The Fund may, from time to time, include its yields
     ------------------                                                      
and effective yields in advertisements or reports to shareholders or prospective
investors.  Quotations of yield for the Fund are based on the investment income
per share earned during a particular seven-day or thirty-day period, less
expenses accrued during a period ("net investment income") and are computed by
dividing net investment income by the offering price per share on the last date
of the period, according to the following formula:

                          YIELD - 2[(a - b + 1)/6/ -1]
                                     -----            

                                       Cd
                                        
     where a = dividends and interest earned during the period, b = expenses
accrued for the period (net of any reimbursements), c = the average daily number
of shares outstanding during the period that were entitled to receive dividends,
and d = the maximum offering price per share on the last day of the period.

     EFFECTIVE YIELD:  Effective yields for the Fund are based on the change in
     ---------------                                                           
the value of a hypothetical investment (exclusive of capital changes) over a
particular seven-day (or thirty-day) period, less a pro-rata share of the Fund's
expenses accrued over that period (the "base period"), and stated as a
percentage of the investment at the start of the base period (the "base period
return").  The base period return is then annualized multiplying by 365/7 (or
365/30 for thirty-day yield), with the resulting yield figure carried to at
least the nearest hundredth of one percent.  "Effective yield" for the Fund
assumes that all dividends received during the period have been reinvested.
Calculation of "effective yield" begins with the same "base period return" used
in the calculation of yield, which is then annualized to reflect weekly
compounding pursuant to the following formula:

         Effective Seven-Day Yield = [(Base Period Return +1)365/7]-1.

   yield information reflects the performance of the predecessor portfolio's
   shares.
 
     From time to time and only to the extent the comparison is appropriate for
a Fund or a Class of shares, the Company may quote the performance or price-
earning ratio of a Fund or Class in advertising and other types of literature as
compared to the performance of the S&P Index, the Dow Jones Industrial Average,
the Lehman Brothers 20+ Treasury Index, the Lehman Brothers 5-7 Year Treasury
Index, Donoghue's Money Fund 

                                      16

Averages, Real Estate Investment Averages (as reported by the National
Association of Real Estate Investment Trusts), Gold Investment Averages
(provided by World Gold Council), Bank Averages (which are calculated from
figures supplied by the U.S. League of Savings Institutions based on effective
annual rates of interest on both passbook and certificate accounts), average
annualized certificate of deposit rates (from the Federal Reserve G-13
Statistical Releases or the Bank Rate Monitor), the Salomon One Year Treasury
Benchmark Index, the Consumer Price Index (as published by the U.S. Bureau of
Labor Statistics), other managed or unmanaged indices or performance data of
bonds, municipal securities, stocks or government securities (including data
provided by Ibbotson Associates), or by other services, companies, publications
or persons who monitor mutual funds on overall performance or other criteria.
The S&P Index and the Dow Jones Industrial Average are unmanaged indices of
selected common stock prices. The performance of the Fund or the Class also may
be compared to that of other mutual funds having similar objectives. This
comparative performance could be expressed as a ranking prepared by Lipper
Analytical Services, Inc., CDA Investment Technologies, Inc., Bloomberg
Financial Markets or Morningstar, Inc., independent services which monitor the
performance of mutual funds. The Fund's performance will be calculated by
relating net asset value per share at the beginning of a stated period to the
net asset value of the investment, assuming reinvestment of all gains
distributions and dividends paid, at the end of the period. The Fund's
comparative performance will be based on a comparison of yields, as described
above, or total return, as reported by Lipper, Survey Publications, Donoghue or
Morningstar, Inc.

     Any such comparisons may be useful to investors who wish to compare past
performance of the Fund or the Class with that of competitors.  Of course, past
performance cannot be a guarantee of future results.  The Company also may
include, from time to time, a reference to certain marketing approaches of the
Distributor, including, for example, a reference to a potential shareholder
being contacted by a selected broker or dealer.  General mutual fund statistics
provided by the Investment Company Institute may also be used.

     The Company also may use the following information in advertisements and
other types of literature, only to the extent the information is appropriate for
the Fund:  (i) the Consumer Price Index may be used to assess the real rate of
return from an investment in a Fund; (ii) other government statistics,
including, but not limited to, The Survey of Current Business, may be used to
illustrate investment attributes of the Fund or the general economic, business,
investment, or financial environment in which the Fund operates; (iii) the
effect of tax-deferred compounding on the investment returns of the Fund, or on
returns in general, may be illustrated by graphs, charts, etc., where such
graphs or charts would compare, at various points in time, the return from an
investment in the Fund (or returns in general) on a tax-deferred basis (assuming
reinvestment of capital gains and dividends and assuming one or more tax rates)
with the return on a taxable basis; and (iv) the sectors or industries in which
the Fund invests may be compared to relevant indices of stocks or surveys (e.g.,
S&P Industry Surveys) to

<PAGE>
 
evaluate the Fund's historical performance or current or potential value with
respect to the particular industry or sector.

     In addition, the Company also may use, in advertisements and other types of
literature, information and statements: (1) showing that bank savings accounts
offer a guaranteed return of principal and a fixed rate of interest, but no
opportunity for capital growth; and (2)  describing Wells Fargo Bank, and its
affiliates and predecessors, as one of the first investment managers to advise
investment accounts using asset allocation and index strategies.  The Company
also may include in advertising and other types of literature information and
other data from reports and studies prepared by the Tax Foundation, including
information regarding federal and state tax levels and the related "Tax Freedom
Day."

     The Company also may discuss in advertising and other types of literature
that the Fund has been assigned a rating by a nationally recognized statistical
rating organization ("NRSRO"), such as Standard & Poor's Corporation.  Such
rating would assess the creditworthiness of the investments held by the Fund.
The assigned rating would not be a recommendation to purchase, sell or hold the
Fund's shares since the rating would not comment on the market price of the
Fund's shares or the suitability of the Fund for a particular investor.  In
addition, the assigned rating would be subject to change, suspension or
withdrawal as a result of changes in, or unavailability of, information relating
to the Fund or its investments.  The Company may compare the Fund's performance
with other investments which are assigned ratings by NRSROs.  Any such
comparisons may be useful to investors who wish to compare the Fund's past
performance with other rated investments.

     From time to time, the Fund may use the following statements, or variations
thereof, in advertisements and other promotional materials:  "Wells Fargo Bank,
as a Shareholder Servicing Agent for the Stagecoach Funds, provides various
services to its customers that are also shareholders of the Funds.  These
services may include access to Stagecoach Funds' account information through
Automated Teller Machines (ATMs), the placement of purchase and redemption
requests for shares of the Funds through ATMs and the availability of combined
Wells Fargo Bank and Stagecoach Funds account statements."

     The Company also may disclose, in advertising and other types of
literature, information and statements that Wells Fargo Investment Management
("WFIM"), a division of Wells Fargo Bank, is listed in the top 100 by
Institutional Investor magazine in its July 1996 survey "America's Top 300 Money
Managers."  This survey ranks money managers in several asset categories.  The
Company may also disclose in advertising and other types of sales literature the
assets and categories of assets under management by the Company's investment
adviser.  The Company may also disclose in advertising and other types of sales
literature the assets and categories of assets under management by a fund's
investment adviser or sub-adviser and the total amount of assets and mutual fund
assets managed by Wells Fargo Bank.  As of August 1, 1996, Wells Fargo Bank and
its affiliates provided investment Advisory services for approximately 

                                      18
<PAGE>
 
$57 billion of assets of individual, trusts, estates and institutions and $19
billion of mutual fund assets.

     The Company also may discuss in advertising and other types of literature
the features, terms and conditions of Wells Fargo Bank accounts through which
investments in the Funds may be made via a "sweep" arrangement, including,
without limitation, the Managed Sweep Account, Money Market Checking Account,
California Tax-Free Money Market Checking Account, Money Market Access Account
and California Tax-Free Money Market Access Account (collectively, the "Sweep
Accounts").  Such advertisements and other literature may include, without
limitation, discussions of such terms and conditions as the minimum deposit
required to open a Sweep Account, a description of the yield earned on shares of
the Funds through a Sweep Account, a description of any monthly or other service
charge on a Sweep Account and any minimum required balance to waive such service
charges, any overdraft protection plan offered in connection with a Sweep
Account, a description of any ATM or check privileges offered in connection with
a Sweep Account and any other terms, conditions, features or plans offered in
connection with a Sweep Account.  Such advertising or other literature may also
include a discussion of the advantages of establishing and maintaining a Sweep
Account, and may include statements from customers as to the reasons why such
customers have established and maintained a Sweep Account.

     The Company may disclose in advertising and other types of literature that
investors can open and maintain Sweep Accounts over the Internet or through
other electronic channels (collectively, "Electronic Channels").  Such
advertising and other literature may discuss the investment options available to
investors, including the types of accounts and any applicable fees.  Such
advertising and other literature may disclose that Wells Fargo Bank is the first
major bank to offer an on-line application for a mutual fund account that can be
filled out completely through Electronic Channels.  Advertising and other
literature may disclose that Wells Fargo Bank may maintain Web sites, pages or
other information sites accessible through Electronic Channels (an "Information
Site") and may describe the contents and features of the Information Site and
instruct investors on how to access the Information Site and open a Sweep
Account.  Advertising and other literature may also disclose the procedures
employed by Wells Fargo Bank to secure information provided by investors,
including disclosure and discussion of the tools and services for accessing
Electronic Channels.  Such advertising or other literature may include
discussions of the advantages of establishing and maintaining a Sweep Account
through Electronic Channels and testimonials from Wells Fargo Bank customers or
employees and may also include descriptions of locations where product
demonstrations may occur.  The Company may also disclose the ranking of Wells
Fargo Bank as one of the largest money managers in the United States.


                       DETERMINATION OF NET ASSET VALUE

     Net asset value per share for the Fund is determined as of 9:00 a.m. and
1:00 p.m. (Pacific time) on each day the Fund is open for business.  Expenses
and fees, including 

                                      19
<PAGE>
 
advisory fees, are accrued daily and are taken into account for the purpose of
determining the net asset value of the Fund's shares.

     As indicated under "Determination of Net Asset Value, Dividends and
Distributions" in the Prospectus, the Fund uses the amortized cost method to
determine the value of its portfolio securities pursuant to Rule 2a-7 under the
Act.  The amortized cost method involves valuing a security at its cost and
amortizing any discount or premium over the period until maturity, regardless of
the impact of fluctuating interest rates on the market value of the security.
While this method provides certainty in valuation, it may result in periods
during which the value, as determined by amortized cost, is higher or lower than
the price that the Fund would receive if the security were sold.  During these
periods the yield to investors may differ somewhat from that which could be
obtained from a similar fund that uses a method of valuation based upon market
prices.  Thus, during periods of declining interest rates, if the use of the
amortized cost method resulted in a lower value of the Fund's investments on a
particular day, a prospective investor in the Fund would be able to obtain a
somewhat higher yield than would result from investment in a fund using solely
market values, and existing Fund investors would receive correspondingly less
income.  The converse would apply during periods of rising interest rates.

     Rule 2a-7 provides that in order to value its portfolio using the amortized
cost method, the Fund must maintain a dollar-weighted average portfolio maturity
of 90 days or less, purchase securities having remaining maturities (as defined
in Rule 2a-7) of thirteen months or less and invest only in Eligible Securities
determined by the Company's Board of Directors to present minimal credit risks.
The maturity of an instrument is generally deemed to be the period remaining
until the date when the principal amount thereof is due or the date on which the
instrument is to be redeemed.  However, Rule 2a-7 provides that the maturity of
an instrument may be deemed shorter in the case of certain instruments,
including certain variable and floating rate instruments subject to demand
features.  Pursuant to the Rule, the Board is required to establish procedures
designed to stabilize, to the extent reasonably possible, the Fund's net asset
value.  Such procedures include review of the Fund's portfolio by the Board of
Directors, at such intervals as it may deem appropriate, to determine whether
the Fund's net asset value calculated by using available market quotations
deviates within 1/2 of 1% of the value based on amortized cost.  The extent of
any deviation will be examined by the Board of Directors.  If such deviation
exceeds 1/2 of 1%, the Board will promptly consider what action, if any, will be
initiated.  In the event the Board determines that a deviation exists that may
result in material dilution or other unfair results to investors, the Board will
take such corrective action as it regards as necessary and appropriate,
including the sale of portfolio instruments prior to maturity to realize capital
gains or losses or to shorten average portfolio maturity, withholding dividends
or establishing a net asset value by using available market quotations.  It is
the intention of the Fund to maintain a per share net asset value of $1.00, but
there can be no assurance that it will do so.

     Instruments having variable or floating interest rates or demand features
may be deemed to have remaining maturities as follows: (a) a government security
with a variable rate of interest readjusted no less frequently than every
thirteen months may be deemed to 

                                      20
<PAGE>
 
have a maturity equal to the period remaining until the next readjustment of the
interest rate; (b) an instrument with a variable rate of interest, the principal
amount of which is scheduled on the face of the instrument to be paid in
thirteen months or less, may be deemed to have a maturity equal to the period
remaining until the next readjustment of the interest rate; (c) an instrument
with a variable rate of interest that is subject to a demand feature may be
deemed to have a maturity equal to the longer of the period remaining until the
next readjustment of the interest rate or the period remaining until the
principal amount can be recovered through demand; (d) an instrument with a
floating rate of interest that is subject to a demand feature may be deemed to
have a maturity equal to the period remaining until the principal amount can be
recovered through demand; and (e) a repurchase agreement may be deemed to have a
maturity equal to the period remaining until the date on which the repurchase of
the underlying securities is scheduled to occur or, where no date is specified
but the agreement is subject to demand, the notice period applicable to a demand
for the repurchase of the securities.


                ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

     Shares may be purchased on any day the Fund is open for business.  The Fund
is open for business each day the NYSE is open for trading (a "Business Day").
Currently, the NYSE is closed on New Year's Day, Martin Luther King, Jr. Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day and Christmas Day.

     Payment for shares may, in the discretion of the adviser, be made in the
form of securities that are permissible investments for the Fund.  For further
information about this form of payment please contact Stephens. In connection
with an in-kind securities payment, the Fund will require, among other things,
that the securities be valued on the day of purchase in accordance with the
pricing methods used by the Fund and that the Fund receives satisfactory
assurances that (i) it will have good and marketable title to the securities
received by it; (ii) that the securities are in proper form for transfer to the
Fund; and (iii) adequate information will be provided concerning the basis and
other matters relating to the securities.

     Under the 1940 Act, the Fund may suspend the right of redemption or
postpone the date of payment upon redemption for any period during which the
NYSE is closed (other than customary weekend and holiday closings, or during
which trading is restricted, or during which as determined by the SEC by rule or
regulation) an emergency exists as a result of which disposal or valuation of
portfolio securities is not reasonably practicable, or for such periods as the
SEC may permit.  The Company may also redeem shares involuntarily or make
payment for redemption in securities or other property if it appears appropriate
to do so in light of the Company's responsibilities under the 1940 Act.  In
addition, the Company may redeem shares involuntarily to reimburse the Fund for
any losses sustained by reason of the failure of a shareholder to make full
payment for shares purchased or to collect any charge relating to a transaction
effected for the benefit of a 

                                      21
<PAGE>
 
shareholder which is applicable to shares of the Fund as provided from time to
time in the Prospectus.

                       
                            PORTFOLIO TRANSACTIONS

     The Company has no obligation to deal with any dealer or group of dealers
in the execution of transactions in portfolio securities.  Subject to policies
established by the Company's Board of Directors, Wells Fargo Bank is responsible
for the Fund's portfolio decisions and the placing of portfolio transactions.
In placing orders, it is the policy of the Company to obtain the best results
taking into account the dealer's general execution and operational facilities,
the type of transaction involved and other factors such as the dealer's risk in
positioning the securities involved.  While Wells Fargo Bank generally seeks
reasonably competitive spreads or commissions, the Fund will not necessarily be
paying the lowest spread or commission available.

     Purchases and sales of non-equity securities usually will be principal
transactions.  Portfolio securities normally will be purchased or sold from or
to dealers serving as market makers for the securities at a net price.  The Fund
also will purchase portfolio securities in underwritten offerings and may
purchase securities directly from the issuer.  Generally, municipal obligations
and taxable money market securities are traded on a net basis and do not involve
brokerage commissions.  The cost of executing the Fund's portfolio securities
transactions will consist primarily of dealer spreads and underwriting
commissions.  Under the Act, persons affiliated with the Company are prohibited
from dealing with the Company as a principal in the purchase and sale of
securities unless an exemptive order allowing such transactions is obtained from
the Commission or an exemption is otherwise available.  The Fund may purchase
securities from underwriting syndicates of which Stephens or Wells Fargo Bank is
a member under certain conditions in accordance with the provisions of a rule
adopted under the Act and in compliance with procedures adopted by the Board of
Directors.

     Wells Fargo Bank, as the Investment Adviser of the Fund, may, in
circumstances in which two or more dealers are in a position to offer comparable
results for the Fund portfolio transaction, give preference to a dealer that has
provided statistical or other research services to Wells Fargo Bank.  By
allocating transactions in this manner, Wells Fargo Bank is able to supplement
its research and analysis with the views and information of securities firms.
Information so received will be in addition to, and not in lieu of, the services
required to be performed by Wells Fargo Bank under the Advisory Contracts, and
the expenses of Wells Fargo Bank will not necessarily be reduced as a result of
the receipt of this supplemental research information.  Furthermore, research
services furnished by dealers through which Wells Fargo Bank places securities
transactions for the Fund may be used by Wells Fargo Bank in servicing its other
accounts, and not all of these services may be used by Wells Fargo Bank in
connection with advising the Fund.

securities (pooled repurchase agreements) of its "regular brokers or dealers" or
their parents, as defined in the 1940 Act as follows.

     Portfolio Turnover.  The portfolio turnover rate is not a limiting factor
     ------------------                                                       
when Wells Fargo Bank deems portfolio changes appropriate.  Changes may be made
in the portfolios consistent with the investment objectives and policies of the
Fund whenever such changes are believed to be in the best interests of the Fund
and its shareholders. The portfolio turnover rate is calculated by dividing the
lesser of purchases or sales of portfolio securities by the average monthly
value of the Fund's portfolio securities. For purposes of this calculation,
portfolio securities exclude all securities having a maturity when purchased of
one year or less.  Portfolio turnover generally involves some expenses to the
Fund, including brokerage commissions or dealer mark-ups and other transaction
costs on the sale of securities and the reinvestment in other securities.
Portfolio turnover also can generate short-term capital gain tax consequences.
Portfolio turnover rate is not a limiting factor when Wells Fargo Bank deems
portfolio changes appropriate.


                                 FUND EXPENSES

     From time to time, Wells Fargo Bank and Stephens may waive fees from the
Fund in whole or in part.  Any such waiver will reduce the Fund's expenses and,
accordingly, have a favorable impact on it's performance.  Except for the
expenses borne by Wells Fargo Bank and Stephens, the Company bears all costs of
its operations, including the compensation of its Directors who are not
affiliated with Stephens or Wells Fargo Bank or any of their affiliates;
advisory, shareholder servicing and administration fees; payments pursuant to
any Plan; interest charges; taxes; fees and expenses of its independent
auditors, legal counsel, transfer agent and dividend disbursing agent; expenses
of redeeming shares; expenses of preparing and printing Prospectuses (except the
expense of printing and mailing Prospectuses used for promotional purposes,
unless otherwise payable pursuant to a Plan), shareholders' reports, notices,
proxy statements and reports to regulatory agencies; insurance premiums and
certain expenses relating to insurance coverage; trade association membership
dues; brokerage and other expenses connected with the execution of portfolio
transactions; fees and expenses of its custodian, including those for keeping
books and accounts and calculating the NAV per share of the Fund; expenses of
shareholders' meetings; expenses relating to the issuance, registration and
qualification of the Fund's shares; pricing services and any extraordinary
expenses.  Expenses attributable to the Fund are charged against  Fund assets.
General expenses of the Company are allocated among all of the funds of the
Company, including the Fund, in a manner proportionate to the net assets of the
Fund, on a transactional basis, or on such other basis as the Company's Board of
Directors deems equitable.

                             FEDERAL INCOME TAXES

     The following information supplements and should be read in conjunction
with the Prospectus section entitled "Taxes."  The Prospectus describes
generally the tax treatment of distributions by the Fund.  This section of the
SAI includes additional information concerning income taxes.

     General.  The Company intends to qualify the Fund as a regulated investment
     -------                                                                    
company under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code"), as long as such qualification is in the best interest of the Fund's
shareholders.  The Fund will be treated as a separate entity for tax purposes
and thus the provisions of the Code applicable to regulated investment companies
will generally be applied to the Fund, rather than to the Company as a whole.
In addition, net capital gain, net investment income, and operating expenses
will be determined separately for the Fund.  As a regulated investment company,
the Fund will not be taxed on its net investment income and capital gains
distributed to its shareholders.

     Qualification as a regulated investment company under the Code requires,
among other things, that (a) the Fund derive at least 90% of its annual gross
income from dividends, interest, certain payments with respect to securities
loans, gains from the sale or other disposition of stock or securities or
foreign currencies (to the extent such currency gains are directly related to
the regulated investment company's principal business of investing in stock or
securities) and other income (including but not limited to gains from options,
futures or forward contracts) derived with respect to its business of investing
in such stock, securities or currencies; and (b) the Fund diversify its holdings
so that, at the end of each quarter of the taxable year, (i) at least 50% of the
market value of the Fund's assets is represented by cash, government securities
and other securities limited in respect of any one issuer to an amount not
greater than 5% of the Fund's 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
obligations and the securities of other regulated investment companies), or in
two or more issuers which the Fund controls and which are determined to be
engaged in the same or similar trades or businesses.

     The Fund must also distribute or be deemed to distribute to their
shareholders at least 90% of its net investment income earned in each taxable
year.  In general, these distributions must actually or be deemed to be made in
the taxable year.  However, in certain circumstances, such distributions may be
made in the 12 months following the taxable year.  The Fund intends to pay out
substantially all of its net investment income and net realized capital gains
(if any) for each year.

     In addition, a regulated investment company must, in general, derive less
than 30% of its gross income from the sale or other disposition of securities or
options thereon held for less than three months.  However, this restriction has
been repealed with respect to a regulated investment company's taxable years
beginning after August 5, 1997.

                                      24

     Excise Tax.  A 4% nondeductible excise tax will be imposed on the Fund
     ----------                                                            
(other than to the extent of its tax-exempt interest income) to the extent it
does not meet certain minimum distribution requirements by the end of each
calendar year.  The Fund intends to actually or be deemed to distribute
substantially all of its net investment income and net capital gains by the end
of each calendar year and, thus, expects not to be subject to the excise tax.

     Taxation of Fund Investments.  Except as provided herein, gains and losses
     ----------------------------                                              
on the sale of portfolio securities by the Fund will generally be capital gains
and losses.  Such gains and losses will ordinarily be long-term capital gains
and losses if the securities have been held by the Fund for more than one year
at the time of disposition of the securities.

     Gains recognized on the disposition of a debt obligation (including tax-
exempt obligations purchased after April 30, 1993) purchased by the Fund at a
market discount (generally at a price less than its principal amount) will be
treated as ordinary income to the extent of the portion of market discount which
accrued, but was not previously recognized pursuant to an available election,
during the term the Fund held the debt obligation.

     Capital Gain Distributions.  Distributions which are designated by the Fund
     --------------------------                                                 
as capital gain distributions will be taxed to shareholders as long-term capital
gain (to the extent such dividends do exceed the Fund's actual net capital gain
for the taxable year), regardless of how long a shareholder has held Fund
shares.  Such distributions will be designated as capital gain distributions in
a written notice mailed by the Fund to its shareholders not later than 60 days
after the close of the Fund's taxable year.

     The Taxpayer Relief Act of 1997 (the "1997 Act") created several new
categories of capital gains applicable to noncorporate taxpayers.  Under prior
law, noncorporate taxpayers were generally taxed at a maximum rate of 28% on net
capital gain (generally, the excess of net long-term capital gain over net
short-term capital loss).  Noncorporate taxpayers are now generally taxed at a
maximum rate of 20% on net capital gain attributable to gains realized on the
sale of property held for greater than 18 months, and a maximum rate of 28% on
net capital gain attributable to gain realized on the sale of property held for
greater than one year and not more than 18 months.  The 1997 Act retains the
treatment of short term capital gain or loss (generally, gain or loss
attributable to capital assets held for 1 year or less) and did not affect the
taxation of capital gains in the hands of corporate taxpayers.

     Under the 1997 Act, the Treasury is authorized to issue regulations for
application of the reduced capital gains tax rates to pass-through entities,
including regulated investment companies, such as the Fund.  Noncorporate
shareholders of the Fund may therefore qualify for the reduced rate of tax on
capital gain dividends paid by the Funds.

     Other Distributions.  Although dividends will be declared daily based on
     -------------------                                                     
the Fund's daily earnings, for federal income tax purposes, the Fund's earnings
and profits will be determined at the end of each taxable year and will be
allocated pro rata over the 

                                      25
<PAGE>
 
entire year. For federal income tax purposes, only amounts paid out of earnings
and profits will qualify as dividends. Thus, if during a taxable year the Fund's
declared dividends (as declared daily throughout the year) exceed the Fund's net
income (as determined at the end of the year), only that portion of the year's
distributions which equals the year's earnings and profits will be deemed to
have constituted a dividend. It is expected that the Fund's net income, on an
annual basis, will equal the dividends declared during the year.

     Disposition of Fund Shares.  A disposition of Fund shares pursuant to
     --------------------------                                           
redemption (including a redemption in-kind) or exchanges will ordinarily result
in a taxable capital gain or loss, depending on the amount received for the
shares (or are deemed to receive in the case of an exchange) and the cost of the
shares.

     If a shareholder exchanges or otherwise disposes of Fund shares within 90
days of having acquired such shares and if, as a result of having acquired those
shares, the shareholder subsequently pays a reduced sales charge on a new
purchase of shares of the Fund or a different regulated investment company, the
sales charge previously incurred acquiring the Fund's shares shall not be taken
into account (to the extent such previous sales charges do not exceed the
reduction in sales charges on the new purchase) for the purpose of determining
the amount of gain or loss on the disposition, but will be treated as having
been incurred in the acquisition of such other shares.  Also, any loss realized
on a redemption or exchange of shares of the Fund will be disallowed to the
extent that substantially identical shares are acquired within the 61-day period
beginning 30 days before and ending 30 days after the shares are disposed of.

     If a shareholder receives a designated capital gain distribution (to be
treated by the shareholder as long-term capital gain) with respect to any Fund
share and such Fund share is held for six months or less, then (unless otherwise
disallowed) any loss on the sale or exchange of that Fund share will be treated
as long-term capital loss to the extent of the designated capital gain
distribution.  This loss disallowance rule does not apply to losses realized
under a periodic redemption plan.

     Federal Income Tax Rates.  As of the printing of this SAI, the maximum
     ------------------------                                              
individual tax rate applicable to ordinary income is 39.6% (marginal tax rates
may be higher for some individuals to reduce or eliminate the benefit of
exemptions and deductions); the maximum individual marginal tax rate applicable
to net capital gain is 28% (however, see "Capital Gain Distributions" above);
and the maximum corporate tax rate applicable to ordinary income and net capital
gain is 35% (marginal tax rates may be higher for some corporations to reduce or
eliminate the benefit of lower marginal income tax rates).  Naturally, the
amount of tax payable by an individual or corporation will be affected by a
combination of tax laws covering, for example, deductions, credits, deferrals,
exemptions, sources of income and other matters.

     Backup Withholding.  The Company may be required to withhold, subject to
     ------------------                                                      
certain exemptions, at a rate of 31% ("backup withholding") on dividends,
capital gain distributions, and redemption proceeds (including proceeds from
exchanges and 

                                      26
<PAGE>
 
redemptions in-kind) paid or credited to an individual Fund shareholder, unless
the shareholder certifies that the Taxpayer Identification Number ("TIN")
provided is correct and that the shareholder is not subject to backup
withholding, or the IRS notifies the Company that the shareholder's TIN is
incorrect or that the shareholder is subject to backup withholding. Such tax
withheld does not constitute any additional tax imposed on the shareholder, and
may be claimed as a credit or refund on the shareholder's federal income tax
return. An investor must provide a valid TIN upon opening or reopening an
account. Failure to furnish a valid TIN to the Company could subject the
investor to penalties imposed by the IRS. Foreign shareholders of the Fund
(described below) are generally not subject to backup withholding.

     Foreign Shareholders.  Under the Code, distributions of net investment
     --------------------                                                  
income by the Fund to a nonresident alien individual, foreign trust (i.e., trust
which a U.S. court is able to exercise primary supervision over administration
of that trust and one or more U.S. persons have authority to control substantial
decisions of that trust), foreign estate (i.e., the income of which is not
subject to U.S. tax regardless of source), foreign corporation, or foreign
partnership (a "foreign shareholder") will be subject to U.S. income tax
withholding (at a rate of 30% or a lower treaty rate, if applicable).
Withholding will not apply if a dividend distribution paid by the Fund to a
foreign shareholder is "effectively connected" with a U.S. trade or business
(or, if an income tax treaty applies, is attributable to a U.S. permanent
establishment of the foreign shareholder), in which case the reporting and
withholding requirements applicable to U.S. residents will apply.  Distributions
of net capital gain are generally not subject to U.S. income tax withholding.

     New Regulations.  On October 6, 1997, the Treasury Department issued new
     ---------------                                                         
regulations (the "New Regulations") which make certain modifications to the
backup withholding, U.S. income tax withholding and information reporting rules
applicable to foreign shareholders.  The New Regulations will generally be
effective for payments made after December 31, 1998, subject to certain
transition rules.  Among other things, the New Regulations will permit the Fund
to estimate the portion of their distributions qualifying as capital gain
distributions for purposes of determining the portion of such distributions paid
to foreign shareholders which will be subject to U.S. income tax withholding.
Prospective investors are urged to consult their own tax advisors regarding the
New Regulations.

     Other Matters.  Investors should be aware that the investments to be made
     -------------                                                            
by the Fund may involve sophisticated tax rules that may result in income or
gain recognition by the Fund without corresponding current cash receipts.
Although the Fund will seek to avoid significant noncash income, such noncash
income could be recognized by the Fund, in which case the Fund may distribute
cash derived from other sources in order to meet the minimum distribution
requirements described above.

     The foregoing discussion and the discussions in the Prospectus applicable
to each shareholder address only some of the federal income tax considerations
generally 

                                      27
<PAGE>
 
affecting investments in the Fund. Each investor is urged to consult his or her
tax advisor regarding specific questions as to federal, state, local and foreign
taxes.

      
                                 CAPITAL STOCK

     The Fund is one of the funds in the Stagecoach Family of Funds. The Company
was organized as a Maryland corporation on September 9, 1991 and currently
offers shares of over thirty funds.

     Most of the Company's funds are authorized to issue multiple classes of
shares, one class generally subject to a front-end sales charge and, in some
cases, one or more classes subject to a contingent-deferred sales charge, that
are offered to retail investors.  Certain of the Company's funds also are
authorized to issue other classes of shares, which are sold primarily to
institutional investors.  Each class of shares in a fund represents an equal,
proportionate interest in a fund with other shares of the same class.
Shareholders of each class bear their pro rata portion of the fund's operating
expenses, except for certain class-specific expenses (e.g., any state securities
registration fees, shareholder servicing fees or distribution fees that may be
paid under Rule 12b-1) that are allocated to a particular class.  Please contact
Stagecoach Shareholder Services at 1-800-222-8222 if you would like additional
information about other funds or classes of shares offered.

     All shares of the Fund have equal voting rights and will be voted in the
aggregate, and not by series, except where voting by a series is required by law
or where the matter involved only affects one series.  For example, a change in
the fund's fundamental investment policy affects only one series and would be
voted upon only by shareholders of the fund involved.  Additionally, approval of
an advisory contract, since it affects only one fund, is a matter to be
determined separately by series.  Approval by the shareholders of one series is
effective as to that series whether or not sufficient votes are received from
the shareholders of the other series to approve the proposal as to those series.

     As used in the Prospectus and in this SAI, the term "majority," when
referring to approvals to be obtained from shareholders of the Fund, means the
vote of the lesser of (i) 67% of the shares of the Fund represented at a meeting
if the holders of more than 50% of the outstanding shares of the Fund are
present in person or by proxy, or (ii) more than 50% of the outstanding shares
of the Fund.  The term "majority," when referring to the approvals to be
obtained from shareholders of the Company as a whole, means the vote of the
lesser of (i) 67% of the Company's shares represented at a meeting if the
holders of more than 50% of the Company's outstanding shares are present in
person or by proxy, or (ii) more than 50% of the Company's outstanding shares.
Shareholders are entitled to one vote for each full share held and fractional
votes for fractional shares held.  The Company may dispense with an annual
meeting of shareholders in any year in which it is not required to elect
Directors under the 1940 Act.

     Each share represents an equal proportional interest in the Fund with each
other share of the same class and is entitled to such dividends and
distributions out of the income 

                                      28
<PAGE>
 
earned on the assets belonging to the Fund as are declared in the discretion of
the Directors. In the event of the liquidation or dissolution of the Company,
shareholders of the Fund are entitled to receive the assets attributable to that
Fund that are available for distribution, and a distribution of any general
assets not attributable to a particular Fund that are available for distribution
in such manner and on such basis as the Directors in their sole discretion may
determine.

     Shares have no preemptive rights or subscription. All shares, when issued
for the consideration described in the Prospectus are fully paid and non-
assessable by the Company.

     As of October 31, 1997, no shareholders were known by the Company to own 5%
or more of the predecessor portfolio's outstanding shares.

                                 SAI APPENDIX

     The following is a description of the ratings given by Moody's and S&P to
corporate bonds and commercial paper.

Corporate Bonds

     Moody's:  The two highest ratings for corporate bonds are "Aaa" and "Aa."
Bonds rated "Aaa" are judged to be of the "best quality" and carry the smallest
amount of investment risk.  Bonds rated "Aa" are of "high quality by all
standards," but margins of protection or other elements make long-term risks
appear somewhat greater than "Aaa" rated bonds.  Moody's applies numerical
modifiers:  1, 2 and 3 in the "Aa" category in its rating system. The modifier 1
indicates that the security ranks in the higher end of its category; the
modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that the
issue ranks in the lower end.

     S&P:  The two highest ratings for corporate bonds are "AAA" and "AA."
Bonds rated "AAA" have the "highest ratings" assigned by S&P and have "an
extremely strong capacity" to pay interest and repay principal.  Bonds rated
"AA" have a "very strong capacity" to pay interest and repay principal and
"differ from the highest rated obligations only in small degree."  The ratings
in the "AA" category may be modified by the addition of a plus or minus sign to
show relative standing within the category.

Commercial Paper

     Moody's:  The highest rating for corporate commercial paper is "P-1"
(Prime-1).  Issuers rated "P-1" have a "superior ability for repayment of senior
short-term debt obligations."

     S&P:  The "A-1" rating for corporate commercial paper is rated "in the
highest category" by S&P and "the obligor's capacity to meet its financial
commitment on the obligation is strong." The "A-1+" rating indicates that said
capacity is "extremely strong." The A-2 rating indicates that said capacity is
"satisfactory," but that corporate and municipal commercial paper rated "A-2" is
"more susceptible" to the adverse effects of changes in economic conditions or
other circumstances than commercial paper rated in higher rating categories.

                                    GENERAL

     The Prime Money Market Mutual Fund operated as Pacific American Liquid
Assets, Inc. from commencement of operations on April 30, 1981, until it was
reorganized as a portfolio of Pacific American Fund on October 1, 1985. On
October 1, 1994, the Fund was reorganized as the Pacific American Money Market
Portfolio of Pacifica Funds Trust ("Pacifica"); and in July 1995, it was renamed
the Pacifica Prime Money Market Fund.

     Prior to August 1, 1990, the Treasury Money Market Mutual Fund was known as
the Short-Term Government Fund. The Treasury Money Market Mutual Fund operated
as a portfolio of Pacific American Fund through October 1, 1994, when it was
reorganized as the Pacific American U.S. Treasury Portfolio, a portfolio of
Pacifica Funds Trust. In July 1995, the Fund was renamed the Pacifica Treasury
Money Market Fund.

     On September 6, 1996, the Pacifica Prime Money Market Fund and Pacifica
Treasury Money Market Fund were reorganized as the Company's Prime Money Market
Mutual Fund and Treasury Money Market Mutual Fund, respectively.


                            INVESTMENT RESTRICTIONS

     Fundamental Investment Policies
     -------------------------------

     Each Fund has adopted the following investment restrictions, all of which
are fundamental policies; that is, they may not be changed without approval by
the vote of the holders of a majority (defined in the Investment Company Act of
1940, as amended (the "1940 Act")) of the outstanding voting securities of such
Fund.

The Prime Money Market Mutual and Treasury Money Market Mutual Funds may not:

     (1)  purchase common stocks and voting securities (including state,
municipal or industrial revenue bonds) except for securities of other investment
companies;

     (2)  borrow money or issue senior securities, except that each Fund may
borrow from banks or enter into reverse repurchase agreements for temporary
purposes in amounts up to one-third of the value of its total assets at the time
of such borrowing.  None of these Funds will purchase securities while its
borrowings (including reverse repurchase agreements) in excess of 5% of its
total assets are outstanding.  As a matter of non-fundamental policy, each Fund
intends to limit its investments in reverse repurchase agreements to no more
than 20% of its total assets;

     (3)  mortgage, pledge, or hypothecate any assets, except in connection with
any such borrowing and in amounts not in excess of one-third of the value of
each such Funds' total assets at the time of its borrowing. Securities held in
escrow or separate accounts in connection with a Fund's investment practices are
not deemed to be pledged for purposes of this investment restriction;

                                       1
<PAGE>
 
     (4)  purchase securities on margin, except for delayed delivery or when-
issued transactions or such short-term credits as are necessary for the
clearance of transactions; or make short sales of securities or, maintain a
short position;

     (5)  write put or call options;

     (6)  underwrite the securities of other issuers, except as each such Fund
may be deemed to be an underwriter in connection with the purchase or sale of
portfolio instruments in accordance with its investment objective and portfolio
management policies;

     (7)  invest in companies for the purpose of exercising control;

     (8)  make loans, except that each such Fund may purchase or hold debt
instruments in accordance with investment objective and policies and may enter
into loans of portfolio securities and repurchase agreements;

     (9)  invest in securities of other investment companies, except as they may
be acquired as part of a merger, consolidation, acquisition of assets or where
otherwise permitted by the 1940 Act; nor

     (10) lend its portfolio securities in excess of one-third of the value of
its total assets.

     Non-Fundamental Investment Policies
     -----------------------------------

     Each Fund has adopted the following non-fundamental policies which may be
changed by a majority vote of the Board of Directors of the Company at any time
and without approval of such Fund's shareholders.

     (1)  Each Fund may invest in shares of other open-end management investment
companies, subject to the limitations of Section 12(d)(1) of the 1940 Act.
Under the 1940 Act, a Fund's investment in such securities currently is limited
to , subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5%  of such Fund's net assets with respect to any one
investment company, and (iii) 10% of such Fund's net assets in the aggregate.
Other investment companies in which the Funds invest can be expected to charge
fees for operating expenses, such as investment advisory and administration
fees, that would be in addition to those charged by a Fund.

     (2)  Each Fund may not invest more than 10% of its net assets in illiquid
securities.  For this purpose, illiquid securities include, among others, (a)
securities that are illiquid by virtue of the absence of a readily available
market or legal or contractual restrictions on resale, (b) fixed time deposits
that are subject to withdrawal penalties and that have maturities of more than
seven days, and (c) repurchase agreements not terminable within seven days.

     (3)  Each Fund may invest up to 25% of its net assets in securities of
foreign governmental and foreign private issuers that are denominated in and pay
interest in U.S. dollars.

                                       2
<PAGE>
 
     (4)  Each Fund may lend securities from its portfolios to brokers, dealers
and financial institutions, in amounts not to exceed (in the aggregate) one-
third of such Fund's total assets.  Any such loans of portfolio securities will
be fully collateralized based on values that are marked to market daily.  The
Funds will not enter into any portfolio security lending arrangement having a
duration of longer than one year.


                  ADDITIONAL PERMITTED INVESTMENT ACTIVITIES

     Set forth below are descriptions of certain investments and additional
investment policies for the Funds.

     Asset-Backed Securities
     -----------------------

     The Funds may purchase asset-backed securities, which are securities backed
by installment contracts, credit-card receivables or other assets.  Asset-backed
securities represent interests in "pools" of assets in which payments of both
interest and principal on the securities are made monthly, thus in effect
"passing through" monthly payments made by the individual borrowers on the
assets that underlie the securities, net of any fees paid to the issuer or
guarantor of the securities.  The average life of asset-backed securities varies
with the maturities of the underlying instruments and is likely to be
substantially less than the original maturity of the assets underlying the
securities as a result of prepayments.  For this and other reasons, an asset-
backed security's stated maturity may be shortened, and the security's total
return may be difficult to predict precisely.

     Bank Obligations
     ----------------

     The Funds may invest in bank obligations, including certificates of
deposit, time deposits, bankers' acceptances and other short-term obligations of
domestic banks, foreign subsidiaries of domestic banks, foreign branches of
domestic banks, and domestic and foreign branches of foreign banks, domestic
savings and loan associations and other banking institutions. With respect to
such securities issued by foreign branches of domestic banks, foreign
subsidiaries of domestic banks, and domestic and foreign branches of foreign
banks, a Fund may be subject to additional investment risks that are different
in some respects from those incurred by a fund which invests only in debt
obligations of U.S. domestic issuers. Such risks include possible future
political and economic developments, the possible imposition of foreign
withholding taxes on interest income payable on the securities, the possible
establishment of exchange controls or the adoption of other foreign governmental
restrictions which might adversely affect the payment of principal and interest
on these securities and the possible seizure or nationalization of foreign
deposits. In addition, foreign branches of U.S. banks and foreign banks may be
subject to less stringent reserve requirements and to different accounting,
auditing, reporting and recordkeeping standards than those applicable to
domestic branches of U.S. banks.

     Certificates of deposit are negotiable certificates evidencing the
obligation of a bank to repay funds deposited with it for a specified period of
time.

                                       3
<PAGE>
 
     Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time at a stated interest rate. Time
deposits which may be held by a Fund will not benefit from insurance from the
Bank Insurance Fund or the Savings Association Insurance Fund administered by
the Federal Deposit Insurance Corporation. Bankers' acceptances are credit
instruments evidencing the obligation of a bank 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 face amount of the instrument upon maturity. The other short-
term obligations may include uninsured, direct obligations, bearing fixed,
floating-or variable-interest rates.

     Commercial Paper
     ----------------

     The Funds may invest in commercial paper. Commercial paper includes short-
term unsecured promissory notes, variable rate demand notes and variable rate
master demand notes issued by domestic and foreign bank holding companies,
corporations and financial institutions as well as similar taxable instruments
issued by government agencies and instrumentalities.

     Floating- and Variable-Rate Obligations
     ---------------------------------------

     The Funds may purchase floating- and variable-rate obligations.  Each Fund
may purchase floating- and variable-rate demand notes and bonds.  These
obligations may have stated maturities in excess of thirteen months, but they
permit the holder to demand payment of principal at any time, or at specified
intervals not exceeding thirteen months.  Variable-rate demand notes include
master demand notes that are obligations that permit a Fund to invest
fluctuating amounts, which may change daily without penalty, pursuant to direct
arrangements between the Fund, as lender, and the borrower.  The interest rates
on these notes may fluctuate from time to time.  The issuer of such obligations
ordinarily has a corresponding right, after a given period, to prepay in its
discretion the outstanding principal amount of the obligations plus accrued
interest upon a specified number of days' notice to the holders of such
obligations.  The interest rate on a floating-rate demand obligation is based on
a known lending rate, such as a bank's prime rate, and is adjusted automatically
each time such rate is adjusted.  The interest rate on a variable-rate demand
obligation is adjusted automatically at specified intervals.  Frequently, such
obligations are secured by letters of credit or other credit support
arrangements provided by banks.  Because these obligations are direct lending
arrangements between the lender and borrower, it is not contemplated that such
instruments generally will be traded, and there generally is no established
secondary market for these obligations, although they are redeemable at face
value.  Accordingly, where these obligations are not secured by letters of
credit or other credit support arrangements, a Fund's right to redeem is
dependent on the ability of the borrower to pay principal and interest on
demand.  Such obligations frequently are not rated by credit rating agencies and
each Fund may invest in obligations which are not so rated only if Wells Fargo
Bank determines that at the time of investment the obligations are of comparable
quality to the other obligations in which such Fund may invest.  Wells Fargo
Bank, on behalf of each Fund, considers on an ongoing basis the creditworthiness
of the issuers of the floating- and variable-rate demand obligations in such
Fund's portfolio.  No Fund will invest more than 10% of the value of its total
net assets in floating- or variable-rate demand obligations whose demand feature

                                       4
<PAGE>
 
is not exercisable within seven days.  Such obligations may be treated as
liquid, provided that an active secondary market exists.

     Foreign Obligations
     -------------------

     Each Fund may invest up to 25% of its assets in high-quality, short-term
(thirteen months or less) debt obligations of foreign branches of U.S. banks or
U.S. branches of foreign banks that are denominated in and pay interest in U.S.
dollars.  Investments in foreign obligations involve certain considerations that
are not typically associated with investing in domestic obligations.  There may
be less publicly available information about a foreign issuer than about a
domestic issuer.  Foreign issuers also are not subject to the same uniform
accounting, auditing and financial reporting standards or governmental
supervision as domestic issuers.  In addition, with respect to certain foreign
countries, taxes may be withheld at the source under foreign income tax laws and
there is a possibility of expropriation or confiscatory taxation, political or
social instability, or diplomatic developments that could affect adversely
investments in, the liquidity of, and the ability to enforce contractual
obligations with respect to, securities of issuers located in those countries.

     Forward Commitments, When-Issued Purchases and Delayed-Delivery 
     ---------------------------------------------------------------
     Transactions
     ------------

     Each Fund may purchase or sell securities on a when-issued or delayed-
delivery basis and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. Securities purchased or
sold on a when-issued, delayed-delivery or forward commitment basis involve a
risk of loss if the value of the security to be purchased declines, or the value
of the security to be sold increases, before the settlement date.  Although each
Fund will generally purchase securities with the intention of acquiring them, a
Fund may dispose of securities purchased on a when-issued, delayed-delivery or a
forward commitment basis before settlement when deemed appropriate by the
adviser.

     Each Fund will segregate cash, U.S. Government obligations or other high-
quality debt instruments in an amount at least equal in value to the Fund's
commitments to purchase when-issued securities.  If the value of these assets
declines, the Fund will segregate additional liquid assets on a daily basis so
that the value of the segregated assets is equal to the amount of such
commitments.

     Illiquid Securities
     -------------------

     The Funds may invest in securities not registered under the 1933 Act and
other securities subject to legal or other restrictions on resale.  Because such
securities may be less liquid than other investments, they may be difficult to
sell promptly at an acceptable price.  Delay or difficulty in selling securities
may result in a loss or be costly to a Fund.  Each Fund may invest up to 10% of
its assets in net illiquid securities.

                                       5
<PAGE>
 
     Letters of Credit
     -----------------

     Certain of the debt obligations (including municipal securities,
certificates of participation, commercial paper and other short-term
obligations) which the Funds may purchase may be backed by an unconditional and
irrevocable letter of credit of a bank, savings and loan association or
insurance company which assumes the obligation for payment of principal and
interest in the event of default by the issuer. Only banks, savings and loan
associations and insurance companies which, in the opinion of Wells Fargo Bank,
are of comparable quality to issuers of other permitted investments of each such
Fund may be used for letter of credit-backed investments.

     Loans of Portfolio Securities
     -----------------------------

     The Funds may lend their portfolio securities to brokers, dealers and
financial institutions, provided:  (1) the loan is secured continuously by
collateral consisting of U.S. Government securities or cash or letters of credit
maintained on a daily marked-to-market basis in an amount at least equal to the
current market value of the securities loaned; (2) the Funds may at any time
call the loan and obtain the return of the securities loaned within five
business days; (3) the Funds will receive any interest or dividends paid on the
loaned securities; and (4) the aggregate market value of securities loaned will
not at any time exceed one third of the total assets of a particular Fund.

     A Fund will earn income for lending its securities because cash collateral
pursuant to such loans will be invested in short-term money market instruments.
In connection with lending securities, the Funds may pay reasonable finders,
administrative and custodial fees.  A Fund will not enter into any security
lending arrangement having a duration longer than one year.  Loans of securities
involve a risk that the borrower may fail to return the securities or may fail
to provide additional collateral. In either case, a Fund could experience delays
in recovering securities or collateral or could lose all or part of the value of
the loaned securities.  When a Fund lends its securities, it continues to
receive interest or dividends on the securities loaned and may simultaneously
earn interest on the collateral received from the borrower or from the
investment of cash collateral in readily marketable, high-quality, short-term
obligations. Although voting rights, or rights to consent, attendant to
securities on loan pass to the borrower, such loans may be called at any time
and will be called so that the securities may be voted by a Fund if a material
event affecting the investment is to occur.  A Fund may pay a portion of the
interest and fees earned from securities lending to a borrower or a placing
broker.  Borrowers and placing brokers may not be affiliated, directly or
indirectly, with Wells Fargo Bank, Stephens Inc. or any of their affiliates.

     Mortgage-Backed Securities
     --------------------------

     The Funds may invest in mortgage-backed securities, including those
representing an undivided ownership interest in a pool of mortgages, such as
certificates of the Government National Mortgage Association ("GNMA") and the
Federal Home Loan Mortgage Corporation ("FHLMC"). These certificates are in most
cases pass-through instruments, through which the holder receives a share of all
interest and principal payments from the mortgages underlying the certificate,
net of certain fees. The average life of a mortgage-backed security varies with
the underlying mortgage instruments, which generally have maximum maturities of
40 years. The 

                                       6
<PAGE>
 
average life is likely to be substantially less than the original maturity of
the mortgage pools underlying the securities as the result of prepayments,
mortgage refinancings or foreclosure. Mortgage prepayment rates are affected by
factors including the level of interest rates, general economic conditions, the
location and age of the mortgage and other social and demographic conditions.
Such prepayments are passed through to the registered holder with the regular
monthly payments of principal and interest and have the effect of reducing
future payments.

     There are risks inherent in the purchase of mortgage-backed securities. For
example, these securities are subject to a risk that default in payment will
occur on the underlying mortgages. In addition to default risk, these securities
are subject to the risk that prepayment on the underlying mortgages will occur
earlier or later or at a lesser or greater rate than expected. To the extent
that adviser's assumptions about prepayments are inaccurate, these securities
may expose the Funds, to significantly greater market risks than expected.

     Municipal Bonds
     ---------------

     The Prime Money Market Mutual Fund may invest in municipal bonds.  The two
principal classifications of municipal bonds are "general obligation" and
"revenue" bonds.  Municipal bonds are debt obligations issued to obtain funds
for various public purposes, including the construction of a wide range of
public facilities such as bridges, highways, housing, hospitals, mass
transportation, schools, streets, and water and sewer works.  Other purposes for
which municipal bonds may be issued include the refunding of outstanding
obligations and obtaining funds for general operating expenses or to loan to
other public institutions and facilities.  Industrial development bonds are a
specific type of revenue bond backed by the credit and security of a private
user.  Certain types of industrial development bonds are issued by or on behalf
of public authorities to obtain funds to provide privately-operated housing
facilities, sports facilities, convention or trade show facilities, airport,
mass transit, port or parking facilities, air or water pollution control
facilities and certain local facilities for water supply, gas, electricity, or
sewage or solid waste disposal.  The Fund may not invest 25% or more of its
respective assets in industrial development bonds.  Assessment bonds, wherein a
specially created district or project area levies a tax (generally on its
taxable property) to pay for an improvement or project may be considered a
variant of either category.  There are, of course, other variations in the types
of municipal bonds, both within a particular classification and between
classifications, depending on numerous factors.

     The Treasury Money Market Mutual Fund may invest in municipal lease
obligations.  Wells Fargo Bank makes determinations concerning the liquidity of
a municipal lease obligation based on factors deemed relevant.  These factors
may include, among others: (1) the frequency of trades and quotes for the
obligation; (2) the number of dealers willing to purchase or sell the security
and the number of other potential buyers; (3) the willingness of dealers to
undertake to make a market in the security; and (4) the nature of the
marketplace trades, including the time needed to dispose of the security, the
method of soliciting offers, and the mechanics of transfer. In addition, the
general credit quality of the municipality and the essentiality to the
municipality of the property covered by the lease may be considered. In
evaluating the credit quality of a municipal lease obligation, the factors to be
considered might include: (1) whether the lease can be canceled; 

                                       7
<PAGE>
 
(2) what assurance there is that the assets represented by the lease can be
sold; (3) the strength of the lessee's general credit (e.g., its debt,
administrative, economic, and financial characteristics); (4) the likelihood
that the municipality will discontinue appropriating funding for the leased
property because the property is no longer deemed essential to the operations of
the municipality (e.g., the potential for an "event of the nonappropriation");
and (5) the legal recourse in the event of failure to appropriate.

     From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on municipal obligations. For example, under federal tax legislation
enacted in 1986, interest on certain private activity bonds must be included in
an investor's alternative minimum taxable income, and corporate investors must
treat all tax-exempt interest as an item of tax preference.  Opinions relating
to the validity of municipal obligations and to the exemption of interest
thereon from federal income tax are rendered by bond counsel to the respective
issuers at the time of issuance. Neither the Funds nor the adviser will review
the proceedings relating to the issuance of municipal obligations or the basis
for such opinions.

     Certain of the municipal obligations held by a Fund may be insured as to
the timely payment of principal and interest. The insurance policies usually are
obtained by the issuer of the municipal obligation at the time of its original
issuance. In the event that the issuer defaults on interest or principal
payment, the insurer will be notified and will be required to make payment to
the bondholders. There is, however, no guarantee that the insurer will meet its
obligations. In addition, such insurance does not protect against market
fluctuations caused by changes in interest rates and other factors.

     The values of outstanding municipal securities will vary as a result of
changing market evaluations of the ability of their issuers to meet the interest
and principal payments (i.e., credit risk).  Such values also will change in
response to changes in the interest rates payable on new issues of municipal
securities (i.e., market risk).  Should such interest rates rise, the values of
outstanding securities, including those held in a Fund's portfolio, will decline
and (if purchased at par value) sell at a discount.  If interests rates fall,
the values of outstanding securities will generally increase and (if purchased
at par value) sell at a premium.  Changes in the value of municipal securities
held in the Fund's portfolio arising from these or other factors will cause
changes in the net asset value per share.

     Other Investment Companies
     --------------------------

     The Funds may invest in shares of other open-end management investment
companies, up to the limits prescribed in Section 12(d) of the 1940 Act.  Under
the 1940 Act, a Fund's investment in such securities currently is limited to,
subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5% of such Fund's net assets with respect to any one
investment company and (iii) 10% of such Fund's net assets in aggregate.  Other
investment companies in which the Funds invest can be expected to charge fees
for operating expenses such as investment advisory and administration fees, that
would be in addition to those charged by the Funds.

                                       8
<PAGE>
 
     Repurchase Agreements
     ---------------------

     Each Fund may enter into repurchase agreements, wherein the seller of a
security to the Fund agrees to repurchase that security from the Fund at a
mutually agreed upon time and price.  A Fund may enter into repurchase
agreements only with respect to securities that could otherwise be purchased by
the Fund.  All repurchase agreements will be fully collateralized at 102% based
on values that are marked to market daily.  The maturities of the underlying
securities in a repurchase agreement transaction may be greater than twelve
months, although the maximum term of a repurchase agreement will always be less
than twelve months.  If the seller defaults and the value of the underlying
securities has declined, a Fund may incur a loss.  In addition, if bankruptcy
proceedings are commenced with respect to the seller of the security, the Fund's
disposition of the security may be delayed or limited.

     Each Fund may not enter into a repurchase agreement with a maturity of more
than seven days, if, as a result, more than 10% of the market value of such
Fund's total net assets would be invested in repurchase agreements with
maturities of more than seven days, restricted securities and illiquid
securities.  A Fund will only enter into repurchase agreements with primary
broker/dealers and commercial banks that meet guidelines established by the
Board of Directors and that are not affiliated with the investment adviser.  The
Funds may participate in pooled repurchase agreement transactions with other
funds advised by Wells Fargo Bank.

     Borrowing and Reverse Repurchase Agreements
     -------------------------------------------

     The Funds intend to limit their borrowings (including reverse repurchase
agreements) during the current fiscal year to not more than 10% of their net
assets.  At the time a Fund enters into a reverse repurchase agreement (an
agreement under which the Fund sells portfolio securities and agrees to
repurchase them at an agreed-upon date and price), it will place in a segregated
custodial account liquid assets such as U.S. Government securities or other
liquid high-grade debt securities having a value equal to or greater than the
repurchase price (including accrued interest) and will subsequently monitor the
account to ensure that such value is maintained. Reverse repurchase agreements
involve the risk that the market value of the securities sold by a Fund may
decline below the price at which the Fund is obligated to repurchase the
securities. Reverse repurchase agreements are considered to be borrowings under
the 1940 Act.

     Unrated and Downgraded Investments
     ----------------------------------

     The Funds may purchase instruments that are not rated if, in the opinion of
Wells Fargo Bank the investment adviser, such obligations are of comparable
quality to other rated investments that are permitted to be purchased by the
Fund.  The Fund may purchase unrated instruments only if they are purchased in
accordance with the Fund's procedures adopted by Company's Board of Directors in
accordance with Rule 2a-7 under the 1940 Act.  After purchase by the Fund, a
security may cease to be rated or its rating may be reduced below the minimum
required for purchase by the Fund.  In the event that a portfolio security
ceases to be an "Eligible Security" or no longer "presents minimal credit
risks," immediate sale of such security is not required, provided that the Board
of Directors has determined that disposal of the portfolio 

                                       9
<PAGE>
 
security would not be in the best interests of the Fund. To the extent the
ratings given by Moody's or S&P may change as a result of changes in such
organizations or their rating systems, the Fund will attempt to use comparable
ratings as standards for investments in accordance with the investment policies.
The ratings of Moody's and S&P are more fully described in the Appendix.

     U.S. Government and U.S. Treasury Obligations
     ---------------------------------------------

     The Funds may invest in obligations of agencies and instrumentalities of
the U.S. Government ("U.S. Government obligations"). The Treasury Money Market
Mutual Fund may invest only in U.S. Government obligations issued or guaranteed
by the U.S. Treasury. Payment of principal and interest on U.S. Government
obligations (i) may be backed by the full faith and credit of the United States
(as with U.S. Treasury bills and GNMA certificates) or (ii) may be backed solely
by the issuing or guaranteeing agency or instrumentality itself (as with FNMA
notes). In the latter case investors must look principally to the agency or
instrumentality issuing or guaranteeing the obligation for ultimate repayment,
which agency or instrumentality may be privately owned. There can be no
assurance that the U.S. Government will provide financial support to its
agencies or instrumentalities where it is not obligated to do so. In addition,
U.S. Government obligations are subject to fluctuations in market value due to
fluctuations in market interest rates. As a general matter, the value of debt
instruments, including U.S. Government obligations, declines when market
interest rates increase and rises when market interest rates decrease. Certain
types of U.S. Government obligations are subject to fluctuations in yield or
value due to their structure or contract terms.

     The Treasury Money Market Mutual Fund may invest only in obligations issued
or guaranteed by the U.S. Treasury such as bills, notes, bonds and certificates
of indebtedness, and in notes and repurchase agreements collateralized or
secured by such obligations ("U.S. Treasury obligations").  U.S. Treasury notes,
bills and bonds differ mainly in the length of their maturity.  The U.S.
Treasury obligations in which the Fund invests may also include "U.S. Treasury
STRIPS," interests in U.S. Treasury obligations reflected in the Federal
Reserve-Book Entry System that represent ownership in either the future interest
payments or the future principal payments on the U.S. Treasury obligations.
U.S. Treasury Strips are "stripped securities."  Stripped securities are issued
at a discount to their face value and may exhibit greater price volatility than
ordinary debt securities because of the manner in which their principal and
interest are paid to investors.  The Treasury Money Market Mutual Fund may
invest in U.S. Treasury STRIPS.

     The Funds may attempt to increase yields by trading to take advantage of
short-term market variations.  This policy could result in high portfolio
turnover, which should not adversely affect the Funds since they do not
ordinarily pay brokerage commissions on the purchase of short-term debt
obligations.

     Nationally Recognized Statistical Ratings Organizations
     -------------------------------------------------------

     The ratings of Moody's Investors Service, Inc., Standard & Poor's Ratings
Group, Duff & Phelps Credit Rating Co., Fitch Investors Service, Inc., Thomson
Bank Watch and IBCA Inc. 

                                      10
<PAGE>
 
represent their opinions as to the quality of debt securities. It should be
emphasized, however, that ratings are general and not absolute standards of
quality, and debt securities with the same maturity, interest rate and rating
may have different yields while debt securities of the same maturity and
interest rate with different ratings may have the same yield. Subsequent to
purchase by a Fund, an issue of debt securities may cease to be rated or its
rating may be reduced below the minimum rating required for purchase by a Fund.
The adviser will consider such an event in determining whether the Fund involved
should continue to hold the obligation.

     The payment of principal and interest on debt securities purchased by the
Funds depends upon the ability of the issuers to meet their obligations. An
issuer's obligations under its debt securities are subject to the provisions of
bankruptcy, insolvency, and other laws affecting the rights and remedies of
creditors, such as the Federal Bankruptcy Code, and laws, if any, which may be
enacted by federal or state legislatures extending the time for payment of
principal or interest, or both, or imposing other constraints upon enforcement
of such obligations or, in the case of governmental entities, upon the ability
of such entities to levy taxes. The power or ability of an issuer to meet its
obligations for the payment of interest and principal of its debt securities may
be materially adversely affected by litigation or other conditions. Further, it
should also be noted with respect to all municipal obligations issued after
August 15, 1986 (August 31, 1986 in the case of certain bonds), the issuer must
comply with certain rules formerly applicable only to industrial development
bonds which, if the issuer fails to observe them, could cause interest on the
municipal obligations to become taxable retroactive to the date of issue.


                                 RISK FACTORS

     Investments in a Fund are not bank deposits or obligations of Wells Fargo
Bank, are not insured by the FDIC and are not insured or guaranteed against loss
of principal.  Therefore, you should be willing to accept some risk with money
you invest in a Fund. Although the Funds seek to maintain a stable net asset
value of $1.00 per share, there is no assurance that they will be able to do so.
The Funds may not achieve as high a level of current income as other mutual
funds that do not limit their investment to the high credit quality instruments
in which the Funds invest.  As with all mutual funds, there can be no assurance
that a Fund will achieve its investment objective.

     The Funds, under the 1940 Act, must comply with certain investment criteria
designed to provide liquidity, reduce risk, and allow the Funds to maintain a
stable net asset value of $1.00 per share.  The Funds' dollar-weighted average
portfolio maturity must not exceed 90 days.  Any security that a Fund purchases
must have a remaining maturity of not more than 397 days (13 months).  In
addition, any security that a Fund purchases must present minimal credit risks
and be of "high quality," or in the case of the Treasury Money Market Mutual
Fund, be of the "highest quality."  "High quality" means to be rated in the top
two rating categories and "highest quality" means to be rated only in the top
rating category, by the requisite NRSROs or, if unrated, determined to be of
comparable quality to such rated securities by Wells Fargo Bank, as the Funds'

Company.

     Each Fund seeks to reduce risk by investing its assets in securities of
various issuers.  In addition, the Funds emphasize safety of principal and high
credit quality. In particular, the internal investment policies of the
investment adviser prohibit the purchase of many types of floating-rate
derivative securities that are considered potentially volatile. The following
types of derivative securities ARE NOT permitted investments for the Funds:

          .    capped floaters (on which interest is not paid when market rates
               move above a certain level);

          .    leveraged floaters (whose interest rate reset provisions are
               based on a formula that magnifies changes in interest rates);

          .    range floaters (which do not pay any interest if market interest
               rates move outside of a specified range);

          .    dual index floaters (whose interest rate reset provisions are
               tied to more than one index so that a change in the relationship
               between these indices may result in the value of the instrument
               falling below face value); and

          .    inverse floaters (which reset in the opposite direction of their
               index).

     Additionally, the Funds may not invest in securities whose interest rate
reset provisions are tied to an index that materially lags short-term interest
rates, such as Cost of Funds Index floaters.  The Funds may invest only in
variable or floating-rate securities that bear interest at a rate that resets
quarterly or more frequently and that resets based on changes in standard money
market rate indices such as U.S. Treasury bills, London Interbank Offered Rate
or LIBOR, the prime rate, published commercial paper rates, federal funds rates,
Public Securities Associates floaters or JJ Kenney index floaters.

     The Treasury Money Market Mutual Fund restricts its investment to U.S.
Treasury obligations that meet all of the standards described above.
Obligations issued or guaranteed by the U.S. Treasury have historically involved
little risk of loss of principal if held to maturity.  However, due to
fluctuations in interest rates, the market value of such obligations may vary
during the period a shareholder owns shares of the Fund.  It should be noted
that neither the United States, nor any agency or instrumentality thereof, has
guaranteed, sponsored or approved the Fund or its shares.

     The portfolio debt instruments of the Funds are subject to credit and
interest-rate risk. Credit risk is the risk that issuers of the debt instruments
in which the Funds invest may default on the payment of principal and/or
interest.  Interest-rate risk is the risk that increases in market interest
rates may adversely affect the value of the debt instruments in which the Funds
invest and hence the value of your investment in a Fund.

     Generally, securities in which the Funds invest will not earn as high a
yield as securities of longer maturity and/or of lesser quality that are more
subject to market volatility.  Each Fund 

                                      12
<PAGE>
 
attempts to maintain the value of its shares at a constant $1.00 per share,
although there can be no assurance that a Fund will always be able to do so.

     As of January 1, 1998, Peter G. Gordon will replace Robert M. Joses on the

     Directors of the Company are compensated annually by the Company and by all
the registrants in each fund complex they serve as indicated above and also are
reimbursed for all out-of-pocket expenses relating to attendance at board
meetings.  The Company, Stagecoach Trust and Life & Annuity Trust are considered
to be members of the same fund complex as such term is defined in Form N-1A
under the 1940 Act (the "Wells Fargo Fund Complex").  Overland Express Funds,
Inc. and Master Investment Trust, two investment companies previously advised by
Wells Fargo Bank, were part of the Wells Fargo Fund Complex prior to December
12, 1997.  These companies are no longer part of the Wells Fargo Fund Complex.
MasterWorks Funds Inc., Master Investment Portfolio, and Managed Series
Investment Trust together form a separate fund complex (the "BGFA Fund
Complex").  Each of the Directors and Officers of the Company serves in the
identical capacity as directors and officers or as trustees and/or officers of
each registered open-end management investment company in both the Wells Fargo
and BGFA Fund Complexes, except for Joseph N. Hankin, who only serves the
aforementioned members of the Wells Fargo Fund Complex.  The Directors are
compensated by other companies and trusts within a fund complex for their
services as directors/trustees to such companies and trusts.  Currently the
Directors do not receive any retirement benefits or deferred compensation from
the Company or any other member of each fund complex.

     As of the date of this SAI, Directors and Officers of the Company as a
group beneficially owned less than 1% of the outstanding shares of the Company.

     INVESTMENT ADVISER.  Wells Fargo Bank provides investment advisory services

to the Funds.  As investment adviser, Wells Fargo Bank furnishes investment
guidance and policy direction in connection with the daily portfolio management
of the Funds.  Wells Fargo Bank furnishes to the Company's Board of Directors
periodic reports on the investment strategy and performance of each Fund.  Wells
Fargo Bank provides the Funds with, among other things, money market and fixed-
income research, analysis and statistical and economic data and information
concerning interest rate and securities markets trends, portfolio composition,
and credit conditions.

     As compensation for its advisory services, Well Fargo Bank is entitled to
receive a monthly fee at the annual rate of 0.25% of each Fund's average daily
net assets.

     For the period indicated below, the Funds paid to Wells Fargo Bank the
following advisory fees and Wells Fargo Bank waived the indicated amounts:

     The Pacifica Prime Money Market and Treasury Money Market Funds were
reorganized as the Company's Prime Money Market Mutual and Treasury Money Market
Mutual Funds on September 6, 1996. Prior to September 6, 1996, the
Administrator, Furman Selz LLC ("Furman Selz"), of the Pacifica predecessor
portfolios provided management and administration services necessary for the
operation of such Funds, pursuant to an Administrative Services Contract. For
these services, Furman Selz was entitled to receive a fee, payable monthly, at
the annual rate of 0.15% of the average daily net assets of the predecessor
portfolios.

     The predecessor portfolios of the Prime Money Market Mutual and Treasury
Money Market Mutual Funds were administered through April 21, 1996 and April 14,
1996, respectively, by the Dreyfus Corporation ("Dreyfus"), at the annual rate
of 0.10% of each such Fund's average daily net assets.

     For the periods begun September 6, 1996 and ended September 30, 1996 and
October 1, 1996 to January 31, 1997, Stephens served as each Fund's sole
Administrator and was entitled to receive a fee, payable monthly, at the annual
rate of 0.05% of each Fund's average daily net assets.

     The following table reflects the total administration fees which the
respective administrators of the Funds and their predecessor portfolios were
paid during the fiscal year ended September 30, 1996.  These amounts also
reflect the net administration fees paid to the respective former

     SPONSOR AND DISTRIBUTOR.  Stephens (the "Distributor"), located at 111
     -----------------------                                               
Center Street, Little Rock, Arkansas 72201, serves as sponsor and distributor
for the Funds.

     SHAREHOLDER SERVICING AGENT.  The Funds have approved a Servicing Plan
     ----------------------------                                          
and have entered into related Shareholder Servicing Agreements, on behalf of the
Administrative Class shares, with financial institutions, including Wells Fargo
Bank.  Under the agreement, Shareholder Servicing Agents (including Wells Fargo
Bank) agree to perform, as agents for their customers, administrative services,
with respect to Fund shares, which include aggregating and transmitting
shareholder orders for purchases, exchanges and redemptions; maintaining
shareholder accounts and records; and providing such other related services as
the Company or a shareholder may reasonably request.  For providing shareholder
services, a Servicing Agent is entitled to a fee from the applicable Fund, not
to exceed 0.15%, on an annualized basis, of the average daily net assets of the
class of shares owned of record or beneficially by the customers of the
Servicing Agent during the period for which payment is being made.  The
Servicing Plans and related forms of shareholder servicing agreements were
approved by the Company's Board of Directors and provide that a Fund shall not
be obligated to make any payments under such plans or related Agreements that
exceed the maximum amounts payable under the Conduct Rules of the National
Association of Securities Dealers, Inc. ("NASD").

     General.  Each Servicing Plan will continue in effect from year to year
     -------                                                                
if such continuance is approved by a majority vote of the Directors of the
Company, including a majority of the Directors who are not "interested persons"
(as defined in the 1940 Act) of the Funds ("Non-Interested Directors").  Any
form of Servicing Agreement related to a Servicing Plan also must be approved by
such vote of the Directors and Non-Interested Directors.  Servicing Agreements
may be terminated at any time, without payment of any penalty, by vote of a
majority of the Board of Directors, including a majority of the Non-Interested
Directors.  No material amendment to the 

                                      18
<PAGE>
 
Servicing Plans or related Servicing Agreements may be made except by a majority
of both the Directors of the Company and the Non-Interested Directors.

       Each Servicing Plan requires that the Administrator shall provide to the
Directors, and the Directors shall review, at least quarterly, a written report
of the amounts expended (and purposes therefor) under the Servicing Plan.

       CUSTODIAN.  Wells Fargo Bank acts as Custodian for each Fund.  The
       ---------                                                         
Custodian, among other things, maintains a custody account or accounts in the
name of each Fund, receives and delivers all assets for each Fund upon purchase
and upon sale or maturity, collects and receives all income and other payments
and distributions on account of the assets of each Fund, and pays all expenses
of each Fund.  For its services as Custodian, Wells Fargo Bank is entitled to
receive fees as follows:  a net asset charge at the annual rate of 0.0167%,
payable monthly, plus specified transaction charges.  Wells Fargo Bank also will
provide portfolio accounting services under the Custody Agreement as follows: a
monthly base fee of $2,000 plus a net asset fee at the annual rate of 0.070% of
the first $50,000,000 of a Fund's average daily net assets, 0.045% of the next
$50,000,000, and 0.020% of the average daily net assets in excess of
$100,000,000.

       TRANSFER AND DIVIDEND DISBURSING AGENT.  Wells Fargo Bank acts as
       --------------------------------------                           
Transfer and Dividend Disbursing Agent for the Funds.  For providing such
services, Wells Fargo Bank is entitled to receive monthly payments at the annual
rate of 0.02% of each Fund's average daily net assets of the Administrative
Class shares.

       UNDERWRITING COMMISSIONS.  The Administrative Class of each Fund does not
       ------------------------                                                 
charge any front-end or contingent-deferred sales charges in connection with the
purchase and redemption of its shares, and therefore pays no underwriting
commissions to the Distributor.

                           PERFORMANCE CALCULATIONS

       The Funds may advertise certain yield and total return information.
Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown.  Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.

       In connection with communicating its performance to current or
prospective shareholders, these figures may also be compared to the performance
of other mutual funds tracked by mutual fund rating services or to unmanaged
indices which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

       Performance information for a Fund or Class of shares in a Fund may be
useful in reviewing the performance of such Fund or Class of shares and for
providing a basis for comparison with investment alternatives.  The yield of a
Fund and the yield of a Class of shares in a Fund, however, may not be
comparable to the yields from investment alternatives because of

                                      19
<PAGE>
 
differences in the foregoing variables and differences in the methods used to
value portfolio securities, compute expenses and calculate yield.

       TOTAL RETURN:  The Funds may advertise certain total return information
       ------------                                                           
computed in the manner described in the Prospectus.  As and to the extent
required by the SEC, an average annual compound rate of return ("T") is computed
by using the redeemable value at the end of a specified period ("ERV") of a
hypothetical initial investment ("P") over a period of years ("n") according to
the following formula:  P(1+T)n=ERV.  In addition, as indicated in each
Prospectus, each Fund also may, at times, calculate total return based on net
asset value per share (rather than the public offering price), in which case the
figures would not reflect the effect of any sales charges that would have been
paid by an investor, or based on the assumption that a sales charge other than
the maximum sales charge (reflecting a Volume Discount) was assessed, provided
that total return data derived pursuant to the calculation described above also
are presented.

       Performance information may be advertised for non-standardized periods,
including year-to-date and other periods less than a year for the Funds.

       In addition to the above performance information, each Fund may also
advertise the cumulative total return of the Fund. Cumulative total return is
based on the overall percentage change in value of a hypothetical investment in
the Fund, assuming all Fund dividends and capital gain distributions are
reinvested, without reflecting the effect of any sales charge that would be paid
by an investor, and is not annualized.

       YIELD CALCULATIONS: The Funds may, from time to time, include their
       ------------------
yields, tax-equivalent yields (if applicable) and effective yields in
advertisements or reports to shareholders

                                      20
<PAGE>
 
or prospective investors. Quotations of yield for the Funds are based on the
investment income per share earned during a particular seven-day or thirty-day
period, less expenses accrued during a period ("net investment income") and are
computed by dividing net investment income by the offering price per share on
the last date of the period, according to the following formula:

                         YIELD - 2[(a - b + 1)/6/ -1]
                                    -----            

                                    Cd

       where a = dividends and interest earned during the period, b = expenses
accrued for the period (net of any reimbursements), c = the average daily number
of shares outstanding during the period that were entitled to receive dividends,
and d = the maximum offering price per share on the last day of the period.

       EFFECTIVE YIELD: Effective yields for the Funds are based on the change
       ---------------
in the value of a hypothetical investment (exclusive of capital changes) over a
particular seven-day (or thirty-day) period, less a pro-rata share of each
Fund's expenses accrued over that period (the "base period"), and stated as a
percentage of the investment at the start of the base period (the "base period
return"). The base period return is then annualized multiplying by 365/7 (or
365/30 for thirty-day yield), with the resulting yield figure carried to at
least the nearest hundredth of one percent. "Effective yield" for the Funds
assumes that all dividends received during the period have been reinvested.
Calculation of "effective yield" begins with the same "base period return" used
in the calculation of yield, which is then annualized to reflect weekly
compounding pursuant to the following formula:

         Effective Seven-Day Yield = [(Base Period Return +1)365/7]-1.

       From time to time and only to the extent the comparison is appropriate
for a Fund or a Class of shares, the Company may quote the performance or price-
earning ratio of a Fund or Class in advertising and other types of literature as
compared to the performance of the S&P Index, the Dow Jones Industrial Average,
the Lehman Brothers 20+ Treasury Index, the Lehman Brothers 5-7 Year Treasury
Index, Donoghue's Money Fund Averages, Real Estate Investment Averages (as
reported by the National Association of Real Estate Investment Trusts), Gold
Investment Averages (provided by World Gold Council), Bank Averages (which are
calculated

                                      21
<PAGE>
 
from figures supplied by the U.S. League of Savings Institutions based on
effective annual rates of interest on both passbook and certificate accounts),
average annualized certificate of deposit rates (from the Federal Reserve G-13
Statistical Releases or the Bank Rate Monitor), the Salomon One Year Treasury
Benchmark Index, the Consumer Price Index (as published by the U.S. Bureau of
Labor Statistics), other managed or unmanaged indices or performance data of
bonds, municipal securities, stocks or government securities (including data
provided by Ibbotson Associates), or by other services, companies, publications
or persons who monitor mutual funds on overall performance or other criteria.
The S&P Index and the Dow Jones Industrial Average are unmanaged indices of
selected common stock prices. The performance of the Funds or a Class also may
be compared to that of other mutual funds having similar objectives. This
comparative performance could be expressed as a ranking prepared by Lipper
Analytical Services, Inc., CDA Investment Technologies, Inc., Bloomberg
Financial Markets or Morningstar, Inc., independent services which monitor the
performance of mutual funds. The Funds' performance will be calculated by
relating net asset value per share at the beginning of a stated period to the
net asset value of the investment, assuming reinvestment of all gains
distributions and dividends paid, at the end of the period. The Funds'
comparative performance will be based on a comparison of yields, as described
above, or total return, as reported by Lipper, Survey Publications, Donoghue or
Morningstar, Inc.

       Any such comparisons may be useful to investors who wish to compare past
performance of the Funds or a Class with that of competitors.  Of course, past
performance cannot be a guarantee of future results.  The Company also may
include, from time to time, a reference to certain marketing approaches of the
Distributor, including, for example, a reference to a potential shareholder
being contacted by a selected broker or dealer.  General mutual fund statistics
provided by the Investment Company Institute may also be used.

       The Company also may use the following information in advertisements and
other types of literature, only to the extent the information is appropriate for
the Fund: (i) the Consumer Price Index may be used to assess the real rate of
return from an investment in a Fund; (ii) other government statistics,
including, but not limited to, The Survey of Current Business, may be used to
illustrate investment attributes of a Fund or the general economic, business,
investment, or financial environment in which a Fund operates; (iii) the effect
of tax-deferred compounding on the investment returns of a Fund, or on returns
in general, may be illustrated by graphs, charts, etc., where such graphs or
charts would compare, at various points in time, the return from an investment
in a Fund (or returns in general) on a tax-deferred basis (assuming reinvestment
of capital gains and dividends and assuming one or more tax rates) with the
return on a taxable basis; and (iv) the sectors or industries in which a Fund
invests may be compared to relevant indices of stocks or surveys (e.g., S&P
Industry Surveys) to evaluate a Fund's historical performance or current or
potential value with respect to the particular industry or sector.

       In addition, the Company also may use, in advertisements and other types
of literature, information and statements: (1) showing that bank savings
accounts offer a guaranteed return of principal and a fixed rate of interest,
but no opportunity for capital growth; and (2) describing Wells Fargo Bank, and
its affiliates and predecessors, as one of the first investment managers to
advise investment accounts using asset allocation and index strategies. The
Company also may

                                      22
<PAGE>
 
include in advertising and other types of literature information and other data
from reports and studies prepared by the Tax Foundation, including information
regarding federal and state tax levels and the related "Tax Freedom Day."

       The Company also may discuss in advertising and other types of literature
that a Fund has been assigned a rating by a nationally recognized statistical
rating organization ("NRSRO"), such as Standard & Poor's Corporation. Such
rating would assess the creditworthiness of the investments held by the Fund.
The assigned rating would not be a recommendation to purchase, sell or hold the
Fund's shares since the rating would not comment on the market price of the
Fund's shares or the suitability of the Fund for a particular investor. In
addition, the assigned rating would be subject to change, suspension or
withdrawal as a result of changes in, or unavailability of, information relating
to the Fund or its investments. The Company may compare the Fund's performance
with other investments which are assigned ratings by NRSROs. Any such
comparisons may be useful to investors who wish to compare the Fund's past
performance with other rated investments.

       From time to time, the Funds may use the following statements, or
variations thereof, in advertisements and other promotional materials: "Wells
Fargo Bank, as a Shareholder Servicing Agent for the Stagecoach Funds, provides
various services to its customers that are also shareholders of the Funds. These
services may include access to Stagecoach Funds' account information through
Automated Teller Machines (ATMs), the placement of purchase and redemption
requests for shares of the Funds through ATMs and the availability of combined
Wells Fargo Bank and Stagecoach Funds account statements."

       The Company also may disclose, in advertising and other types of
literature, information and statements that Wells Fargo Investment Management
("WFIM"), a division of Wells Fargo Bank, is listed in the top 100 by
Institutional Investor magazine in its July 1996 survey "America's Top 300 Money
Managers." This survey ranks money managers in several asset categories. The
Company may also disclose in advertising and other types of sales literature the
assets and categories of assets under management by the Company's investment
adviser. The Company may also disclose in advertising and other types of sales
literature the assets and categories of assets under management by a fund's
investment adviser or sub-adviser and the total amount of assets and mutual fund
assets managed by Wells Fargo Bank. As of August 1, 1997, Wells Fargo Bank and
its affiliates provided investment Advisory services for approximately $57
billion of assets of individual, trusts, estates and institutions and $19
billion of mutual fund assets.

       The Company also may discuss in advertising and other types of literature
the features, terms and conditions of Wells Fargo Bank accounts through which
investments in the Funds may be made via a "sweep" arrangement, including,
without limitation, the Managed Sweep Account, Money Market Checking Account,
California Tax-Free Money Market Checking Account, Money Market Access Account
and California Tax-Free Money Market Access Account (collectively, the "Sweep
Accounts"). Such advertisements and other literature may include, without
limitation, discussions of such terms and conditions as the minimum deposit
required to open a Sweep Account, a description of the yield earned on shares of
the Funds through a Sweep

Account, a description of any monthly or other service charge on a Sweep Account
and any minimum required balance to waive such service charges, any overdraft
protection plan offered in connection with a Sweep Account, a description of any
ATM or check privileges offered in connection with a Sweep Account and any other
terms, conditions, features or plans offered in connection with a Sweep Account.
Such advertising or other literature may also include a discussion of the
advantages of establishing and maintaining a Sweep Account, and may include
statements from customers as to the reasons why such customers have established
and maintained a Sweep Account.

       The Company may disclose in advertising and other types of literature
that investors can open and maintain Sweep Accounts over the Internet or through
other electronic channels (collectively, "Electronic Channels"). Such
advertising and other literature may discuss the investment options available to
investors, including the types of accounts and any applicable fees. Such
advertising and other literature may disclose that Wells Fargo Bank is the first
major bank to offer an on-line application for a mutual fund account that can be
filled out completely through Electronic Channels. Advertising and other
literature may disclose that Wells Fargo Bank may maintain Web sites, pages or
other information sites accessible through Electronic Channels (an "Information
Site") and may describe the contents and features of the Information Site and
instruct investors on how to access the Information Site and open a Sweep
Account. Advertising and other literature may also disclose the procedures
employed by Wells Fargo Bank to secure information provided by investors,
including disclosure and discussion of the tools and services for accessing
Electronic Channels. Such advertising or other literature may include
discussions of the advantages of establishing and maintaining a Sweep Account
through Electronic Channels and testimonials from Wells Fargo Bank customers or
employees and may also include descriptions of locations where product
demonstrations may occur. The Company may also disclose the ranking of Wells
Fargo Bank as one of the largest money managers in the United States.

                       DETERMINATION OF NET ASSET VALUE

       Net asset value per share for the Administrative Class shares of the
Prime Money Market Mutual and Treasury Money Market Mutual Funds is determined
as of 12:00 noon and 1:00 p.m. (Pacific time) on each day the NYSE is open for
business. Expenses and fees, including advisory fees, are accrued daily and are
taken into account for the purpose of determining the net asset value of the
Funds' shares.

       Each Fund uses the amortized cost method to determine the value of its
portfolio securities pursuant to Rule 2a-7 under the 1940 Act. The amortized
cost method involves valuing a security at its cost and amortizing any discount
or premium over the period until maturity, regardless of the impact of
fluctuating interest rates on the market value of the security. While this
method provides certainty in valuation, it may result in periods during which
the value, as determined by amortized cost, is higher or lower than the price
that the Funds would receive if the security were sold. During these periods the
yield to a shareholder may differ somewhat from that which could be obtained
from a similar fund that uses a method of valuation

                                      24
<PAGE>
 
based upon market prices. Thus, during periods of declining interest rates, if
the use of the amortized cost method resulted in a lower value of the Funds'
portfolio on a particular day, a prospective investor in the Funds would be able
to obtain a somewhat higher yield than would result from investment in a fund
using solely market values, and existing Fund shareholders would receive
correspondingly less income. The converse would apply during periods of rising
interest rates.

       Rule 2a-7 provides that in order to value its portfolio using the
amortized cost method, a Fund must maintain a dollar-weighted average portfolio
maturity of 90 days or less, purchase securities having remaining maturities (as
defined in Rule 2a-7) of thirteen months or less and invest only in those high-
quality securities that are determined by the Board of Directors to present
minimal credit risks. The maturity of an instrument is generally deemed to be
the period remaining until the date when the principal amount thereof is due or
the date on which the instrument is to be redeemed. However, Rule 2a-7 provides
that the maturity of an instrument may be deemed shorter in the case of certain
instruments, including certain variable and floating rate instruments subject to
demand features. Pursuant to the Rule, the Board is required to establish
procedures designed to stabilize, to the extent reasonably possible, a Fund's
price per share as computed for the purpose of sales and redemptions at $1.00.
Such procedures include review of the Fund's portfolio holdings by the Board of
Directors, at such intervals as it may deem appropriate, to determine whether
the Fund's net asset value calculated by using available market quotations
deviates from $1.00 per share based on amortized cost. The extent of any
deviation will be examined by the Board of Directors. If such deviation exceeds
1/2 of 1%, the Board will promptly consider what action, if any, will be
initiated. In the event the Board determines that a deviation exists that may
result in material dilution or other unfair results to investors or existing
shareholders, the Board will take such corrective action as it regards as
necessary and appropriate, including the sale of portfolio instruments prior to
maturity to realize capital gains or losses or to shorten average portfolio
maturity, withholding dividends or establishing a net asset value per share by
using available market quotations. It is the intention of the Funds to maintain
a per share net asset value of $1.00, but there can be no assurance that each
Fund will do so.

       Instruments having variable or floating interest rates or demand features
may be deemed to have remaining maturities as follows: (a) a government security
with a variable rate of interest readjusted no less frequently than every
thirteen months may be deemed to have a maturity equal to the period remaining
until the next readjustment of the interest rate; (b) an instrument with a
variable rate of interest, the principal amount of which is scheduled on the
face of the instrument to be paid in thirteen months or less, may be deemed to
have a maturity equal to the period remaining until the next readjustment of the
interest rate; (c) an instrument with a variable rate of interest that is
subject to a demand feature may be deemed to have a maturity equal to the longer
of the period remaining until the next readjustment of the interest rate or the
period remaining until the principal amount can be recovered through demand; (d)
an instrument with a floating rate of interest that is subject to a demand
feature may be deemed to have a maturity equal to the period remaining until the
principal amount can be recovered through demand; and (e) a repurchase agreement
may be deemed to have a maturity equal to the period remaining until the date on
which the repurchase of

                                      25
<PAGE>
 
the underlying securities is scheduled to occur or, where no date is specified
but the agreement is subject to demand, the notice period applicable to a demand
for the repurchase of the securities.

                ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

       Shares may be purchased on any day a Fund is open for business (a
"Business Day"). The Funds are open Monday through Friday and are closed on
federal bank holidays. Currently, those holidays are New Year's Day, President's
Day, Martin Luther King Jr. Day, Memorial Day, Independence Day, Labor Day,
Columbus Day, Veterans Day, Thanksgiving Day and Christmas Day.

       Payment for shares may, in the discretion of the adviser, be made in the
form of securities that are permissible investments for the Funds. For further
information about this form of payment please contact Stephens. In connection
with an in-kind securities payment, the Funds will require, among other things,
that the securities be valued on the day of purchase in accordance with the
pricing methods used by a Fund and that such Fund receives satisfactory
assurances that (i) it will have good and marketable title to the securities
received by it; (ii) that the securities are in proper form for transfer to the
Fund; and (iii) adequate information will be provided concerning the basis and
other matters relating to the securities.

       Under the 1940 Act, the Funds may suspend the right of redemption or
postpone the date of payment upon redemption for any period during which the
NYSE is closed (other than customary weekend and holiday closings, or during
which trading is restricted, or during which as determined by the SEC by rule or
regulation) an emergency exists as a result of which disposal or valuation of
portfolio securities is not reasonably practicable, or for such periods as the
SEC may permit. The Company may also redeem shares involuntarily or make payment
for redemption in securities or other property if it appears appropriate to do
so in light of the Company's responsibilities under the 1940 Act. In addition,
the Company may redeem shares involuntarily to reimburse the Funds for any
losses sustained by reason of the failure of a shareholders to make full payment
for shares purchased or to collect any charge relating to a transaction effected
for the benefit of a shareholder which is applicable to shares of a Fund.

                            PORTFOLIO TRANSACTIONS

       The Company has no obligation to deal with any dealer or group of dealers
in the execution of transactions in portfolio securities. Subject to policies
established by the Company's Board of Directors, Wells Fargo Bank is responsible
for each Fund's portfolio decisions and the placing of portfolio transactions.
In placing orders, it is the policy of the Company to obtain the best results
taking into account the dealer's general execution and operational facilities,
the type of transaction involved and other factors such as the dealer's risk in
positioning the securities involved. While Wells Fargo Bank generally seeks
reasonably competitive spreads or commissions, the Funds will not necessarily be
paying the lowest spread or commission available.

                                      26
<PAGE>
 
       Purchases and sales of non-equity securities usually will be principal
transactions.  Portfolio securities normally will be purchased or sold from or
to dealers serving as market makers for the securities at a net price.  Each of
the Funds also will purchase portfolio securities in underwritten offerings and
may purchase securities directly from the issuer.  Generally, municipal
obligations and taxable money market securities are traded on a net basis and do
not involve brokerage commissions.  The cost of executing a Fund's portfolio
securities transactions will consist primarily of dealer spreads and
underwriting commissions.  Under the Act, persons affiliated with the Company
are prohibited from dealing with the Company as a principal in the purchase and
sale of securities unless an exemptive order allowing such transactions is
obtained from the Commission or an exemption is otherwise available.  The Fund
may purchase securities from underwriting syndicates of which Stephens or Wells
Fargo Bank is a member under certain conditions in accordance with the
provisions of a rule adopted under the Act and in compliance with procedures
adopted by the Board of Directors.

       Wells Fargo Bank, as the Investment Adviser of each of the Funds, may, in
circumstances in which two or more dealers are in a position to offer comparable
results for a Fund portfolio transaction, give preference to a dealer that has
provided statistical or other research services to Wells Fargo Bank.  By
allocating transactions in this manner, Wells Fargo Bank is able to supplement
its research and analysis with the views and information of securities firms.
Information so received will be in addition to, and not in lieu of, the services
required to be performed by Wells Fargo Bank under the Advisory Contracts, and
the expenses of Wells Fargo Bank will not necessarily be reduced as a result of
the receipt of this supplemental research information.  Furthermore, research
services furnished by dealers through which Wells Fargo Bank places securities
transactions for a Fund may be used by Wells Fargo Bank in servicing its other
accounts, and not all of these services may be used by Wells Fargo Bank in
connection with advising the Funds.

       Brokerage Commissions. The Funds did not pay any brokerage commissions on
       ---------------------
portfolio transactions for the nine-month period ended September 30, 1996 and
the six-month period ended March 31, 1997.

       Securities of Regular Broker/Dealers. As of March 31, 1997, the Funds
       ------------------------------------
owned securities of their "regular brokers or dealers" or their parents, as
defined in the Act as follows:

       Portfolio Turnover.  The portfolio turnover rate is not a limiting factor
       ------------------                                                       
when Wells Fargo Bank deems portfolio changes appropriate.  Changes may be made
in the portfolios consistent with the investment objectives and policies of the
Funds whenever such changes are believed to be in the best interests of the
Funds and their shareholders.  The portfolio turnover rate is calculated by
dividing the lesser of purchases or sales of portfolio securities by the average
monthly value of the Fund's portfolio securities.  For purposes of this
calculation, portfolio securities exclude all securities having a maturity when
purchased of one year or less.  Portfolio turnover generally involves some
expenses to the Funds, including brokerage commissions or dealer mark-ups and
other transaction costs on the sale of securities and the reinvestment in other
securities.  Portfolio turnover also can generate short-term capital gain tax
consequences.  Portfolio turnover rate is not a limiting factor when Wells Fargo
Bank deems portfolio changes appropriate.

                                 FUND EXPENSES

       From time to time, Wells Fargo Bank and Stephens may waive fees from the
Funds in whole or in part.  Any such waiver will reduce expenses and,
accordingly, have a favorable impact on a Fund's performance.  Except for the
expenses borne by Wells Fargo Bank and Stephens, the Company bears all costs of
its operations, including the compensation of its Directors who are not
affiliated with Stephens or Wells Fargo Bank or any of their affiliates;
advisory, shareholder servicing and administration fees; payments pursuant to
any Plan; interest charges; taxes; fees and expenses of its independent
accountants, legal counsel, transfer agent and dividend disbursing agent;
expenses of redeeming shares; expenses of preparing and printing prospectuses
(except the expense of printing and mailing prospectuses used for promotional
purposes, unless otherwise payable pursuant to a Plan), shareholders' reports,
notices, proxy statements and reports to regulatory agencies; insurance premiums
and certain expenses relating to insurance coverage; trade association
membership dues; brokerage and other expenses connected with the execution of
portfolio transactions; fees and expenses of its custodian, including those for
keeping books and accounts and calculating the NAV per share of a Fund; expenses
of shareholders' meetings; expenses relating to the issuance, registration and
qualification of a Fund's shares; pricing services, and any extraordinary
expenses.  Expenses attributable to a Fund are charged against a Fund assets.
General expenses of the Company are allocated among all of the funds of the
Company, including a Fund, in a manner proportionate to the net assets of each
Fund, on a transactional basis, or on such other basis as the Company's Board of
Directors deems equitable.

                             FEDERAL INCOME TAXES

       The following information supplements and should be read in conjunction
with the Prospectus section entitled "Taxes." The Prospectus describes generally
the tax treatment of distributions by the Funds. This section of the SAI
includes additional information concerning income taxes.

       General. The Company intends to qualify each Fund as a regulated
       -------
investment company under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code"), as long as

                                      28
<PAGE>
 
such qualification is in the best interest of the Fund's shareholders. Each Fund
will be treated as a separate entity for tax purposes and thus the provisions of
the Code applicable to regulated investment companies will generally be applied
to each Fund, rather than to the Company as a whole. In addition, net capital
gain, net investment income, and operating expenses will be determined
separately for each Fund. As a regulated investment company, each Fund will not
be taxed on its net investment income and capital gains distributed to its
shareholders.

       Qualification as a regulated investment company under the Code requires,
among other things, that (a) each Fund derive at least 90% of its annual gross
income from dividends, interest, certain payments with respect to securities
loans, gains from the sale or other disposition of stock or securities or
foreign currencies (to the extent such currency gains are directly related to
the regulated investment company's principal business of investing in stock or
securities) and other income (including but not limited to gains from options,
futures or forward contracts) derived with respect to its business of investing
in such stock, securities or currencies; and (b) the Fund diversify its holdings
so that, at the end of each quarter of the taxable year, (i) at least 50% of the
market value of the Fund's assets is represented by cash, government securities
and other securities limited in respect of any one issuer to an amount not
greater than 5% of the Fund's 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
obligations and the securities of other regulated investment companies), or in
two or more issuers which the Fund controls and which are determined to be
engaged in the same or similar trades or businesses.

       The Funds must also distribute or be deemed to distribute to their
shareholders at least 90% of their net investment income earned in each taxable
year.  In general, these distributions must actually or be deemed to be made in
the taxable year.  However, in certain circumstances, such distributions may be
made in the 12 months following the taxable year.  The Funds intend to pay out
substantially all of their net investment income and net realized capital gains
(if any) for each year.

       In addition, a regulated investment company must, in general, derive less
than 30% of its gross income from the sale or other disposition of securities or
options thereon held for less than three months.  However, this restriction has
been repealed with respect to a regulated investment company's taxable years
beginning after August 5, 1997.

       Excise Tax.  A 4% nondeductible excise tax will be imposed on each Fund
       ----------                                                             
(other than to the extent of its tax-exempt interest income) to the extent it
does not meet certain minimum distribution requirements by the end of each
calendar year.  Each Fund intends to actually or be deemed to distribute
substantially all of its net investment income and net capital gains by the end
of each calendar year and, thus, expects not to be subject to the excise tax.

       Taxation of Fund Investments. Except as provided herein, gains and losses
       ----------------------------
on the sale of portfolio securities by a Fund will generally be capital gains
and losses. Such gains and losses will ordinarily be long-term capital gains and
losses if the securities have been held by the Fund for more than one year at
the time of disposition of the securities.

                                      29
<PAGE>
 
       Gains recognized on the disposition of a debt obligation (including tax-
exempt obligations purchased after April 30, 1993) purchased by the Fund at a
market discount (generally at a price less than its principal amount) will be
treated as ordinary income to the extent of the portion of market discount which
accrued, but was not previously recognized pursuant to an available election,
during the term the Fund held the debt obligation.

       Capital Gain Distributions. Distributions which are designated by a Fund
       --------------------------
as capital gain distributions will be taxed to shareholders as long-term capital
gain (to the extent such dividends do exceed the Fund's actual net capital gain
for the taxable year), regardless of how long a shareholder has held Fund
shares. Such distributions will be designated as capital gain distributions in a
written notice mailed by the Fund to its shareholders not later than 60 days
after the close of the Fund's taxable year.

       The Taxpayer Relief Act of 1997 (the "1997 Act") created several new
categories of capital gains applicable to noncorporate taxpayers.  Under prior
law, noncorporate taxpayers were generally taxed at a maximum rate of 28% on net
capital gain (generally, the excess of net long-term capital gain over net
short-term capital loss).  Noncorporate taxpayers are now generally taxed at a
maximum rate of 20% on net capital gain attributable to gains realized on the
sale of property held for greater than 18 months, and a maximum rate of 28% on
net capital gain attributable to gain realized on the sale of property held for
greater than one year and not more than 18 months.  The 1997 Act retains the
treatment of short term capital gain or loss (generally, gain or loss
attributable to capital assets held for 1 year or less) and did not affect the
taxation of capital gains in the hands of corporate taxpayers.

       Under the 1997 Act, the Treasury is authorized to issue regulations for
application of the reduced capital gains tax rates to pass-through entities,
including regulated investment companies, such as the Funds.  Noncorporate
shareholders of the Funds may therefore qualify for the reduced rate of tax on
capital gain dividends paid by the Funds.

       Other Distributions. Although dividends will be declared daily based on
       -------------------
each Fund's daily earnings, for federal income tax purposes, the Fund's earnings
and profits will be determined at the end of each taxable year and will be
allocated pro rata over the entire year. For federal income tax purposes, only
amounts paid out of earnings and profits will qualify as dividends. Thus, if
during a taxable year a Fund's declared dividends (as declared daily throughout
the year) exceed the Fund's net income (as determined at the end of the year),
only that portion of the year's distributions which equals the year's earnings
and profits will be deemed to have constituted a dividend. It is expected that
each Fund's net income, on an annual basis, will equal the dividends declared
during the year.

       Disposition of Fund Shares.  A disposition of Fund shares pursuant to
       --------------------------                                           
redemption (including a redemption in-kind) or exchanges will ordinarily result
in a taxable capital gain or loss, depending on the amount received for the
shares (or are deemed to receive in the case of an exchange) and the cost of the
shares.

       If a shareholder exchanges or otherwise disposes of Fund shares within 90
days of having acquired such shares and if, as a result of having acquired those
shares, the shareholder

                                      30
<PAGE>
 
subsequently pays a reduced sales charge on a new purchase of shares of the Fund
or a different regulated investment company, the sales charge previously
incurred acquiring the Fund's shares shall not be taken into account (to the
extent such previous sales charges do not exceed the reduction in sales charges
on the new purchase) for the purpose of determining the amount of gain or loss
on the disposition, but will be treated as having been incurred in the
acquisition of such other shares. Also, any loss realized on a redemption or
exchange of shares of the Fund will be disallowed to the extent that
substantially identical shares are acquired within the 61-day period beginning
30 days before and ending 30 days after the shares are disposed of.

       If a shareholder receives a designated capital gain distribution (to be
treated by the shareholder as long-term capital gain) with respect to any Fund
share and such Fund share is held for six months or less, then (unless otherwise
disallowed) any loss on the sale or exchange of that Fund share will be treated
as long-term capital loss to the extent of the designated capital gain
distribution. In addition, if a shareholder holds Fund shares for six months or
less, any loss on the sale or exchange of those shares will be disallowed to the
extent of the amount of exempt-interest dividends received with respect to the
shares.  The Treasury Department is authorized to issue regulations reducing the
six months holding requirement to a period of not less than the greater of 31
days or the period between regular dividend distributions where a Fund regularly
distributes at least 90% of its net tax-exempt interest, if any.  No such
regulations had been issued as of the date of this SAI.  The loss disallowance
rules described in this paragraph do not apply to losses realized under a
periodic redemption plan.

       Federal Income Tax Rates.  As of the printing of this SAI, the maximum
       ------------------------                                              
individual tax rate applicable to ordinary income is 39.6% (marginal tax rates
may be higher for some individuals to reduce or eliminate the benefit of
exemptions and deductions); the maximum individual marginal tax rate applicable
to net capital gain is 28% (however, see "Capital Gain Distributions" above);
and the maximum corporate tax rate applicable to ordinary income and net capital
gain is 35% (marginal tax rates may be higher for some corporations to reduce or
eliminate the benefit of lower marginal income tax rates).  Naturally, the
amount of tax payable by an individual or corporation will be affected by a
combination of tax laws covering, for example, deductions, credits, deferrals,
exemptions, sources of income and other matters.

       Backup Withholding.  The Company may be required to withhold, subject to
       ------------------                                                      
certain exemptions, at a rate of 31% ("backup withholding") on dividends,
capital gain distributions, and redemption proceeds (including proceeds from
exchanges and redemptions in-kind) paid or credited to an individual Fund
shareholder, unless the shareholder certifies that the Taxpayer Identification
Number ("TIN") provided is correct and that the shareholder is not subject to
backup withholding, or the IRS notifies the Company that the shareholder's TIN
is incorrect or that the shareholder is subject to backup withholding.  Such tax
withheld does not constitute any additional tax imposed on the shareholder, and
may be claimed as a credit or refund on the shareholder's federal income tax
return.  An investor must provide a valid TIN upon opening or reopening an
account.  Failure to furnish a valid TIN to the Company could subject the
investor to penalties imposed by the IRS.  Foreign shareholders of the Funds
(described below) are generally not subject to backup withholding.

                                      31
<PAGE>
 
       Foreign Shareholders. Under the Code, distributions of net investment
       --------------------
income by a Fund to a nonresident alien individual, foreign trust (i.e., trust
which a U.S. court is able to exercise primary supervision over administration
of that trust and one or more U.S. persons have authority to control substantial
decisions of that trust), foreign estate (i.e., the income of which is not
subject to U.S. tax regardless of source), foreign corporation, or foreign
partnership (a "foreign shareholder") will be subject to U.S. income tax
withholding (at a rate of 30% or a lower treaty rate, if applicable).
Withholding will not apply if a dividend distribution paid by a Fund to a
foreign shareholder is "effectively connected" with a U.S. trade or business
(or, if an income tax treaty applies, is attributable to a U.S. permanent
establishment of the foreign shareholder), in which case the reporting and
withholding requirements applicable to U.S. residents will apply. Distributions
of net capital gain are generally not subject to U.S. income tax withholding.

       New Regulations.  On October 6, 1997, the Treasury Department issued new
       ---------------                                                         
regulations (the "New Regulations") which make certain modifications to the
backup withholding, U.S. income tax withholding and information reporting rules
applicable to foreign shareholders.  The New Regulations will generally be
effective for payments made after December 31, 1998, subject to certain
transition rules.  Among other things, the New Regulations will permit the Funds
to estimate the portion of their distributions qualifying as capital gain
distributions for purposes of determining the portion of such distributions paid
to foreign shareholders which will be subject to U.S. income tax withholding.
Prospective investors are urged to consult their own tax advisors regarding the
New Regulations.

       Tax-Deferred Plans. The shares of the Funds are available for a variety
       ------------------
of tax-deferred retirement and other plans, including Individual Retirement
Accounts ("IRA"), Simplified Employee Pension Plans ("SEP-IRA"), Savings
Incentive Match Plans for Employees ("SIMPLE plans"), Roth IRAs, and Education
IRAs, which permit investors to defer some of their income from taxes. Investors
should contact their selling agents for details concerning retirement plans.

       Other Matters. Investors should be aware that the investments to be made
       -------------
by a Fund may involve sophisticated tax rules that may result in income or gain
recognition by the Fund without corresponding current cash receipts. Although
the Funds will seek to avoid significant noncash income, such noncash income
could be recognized by a Fund, in which case the Fund may distribute cash
derived from other sources in order to meet the minimum distribution
requirements described above.

       The foregoing discussion and the discussions in the Prospectus applicable
to each shareholder address only some of the federal income tax considerations
generally affecting investments in a Fund. Each investor is urged to consult his
or her tax advisor regarding specific questions as to federal, state, local and
foreign taxes.

       The Funds are two of the funds in the Stagecoach Family of Funds. The
Company was organized as a Maryland corporation on September 9, 1991, and
currently offers shares of over thirty funds.

       Most of  the Company's funds are authorized to issue multiple classes of
shares, one class generally subject to a front-end sales charge and, in some
cases, classes subject to a contingent-deferred sales charge, that are offered
to retail investors.  Certain of the Company's funds also are authorized to
issue other classes of shares, which are sold primarily to institutional
investors.  Each class of shares in a fund represents an equal, proportionate
interest in a fund with other shares of the same class.  Shareholders of each
class bear their pro rata portion of the fund's operating expenses, except for
certain class-specific expenses (e.g., any state securities registration fees,
shareholder servicing fees or distribution fees that may be paid under Rule 12b-
1) that are allocated to a particular class.  Please contact Stagecoach
Shareholder Services at 1-800-222-8222 if you would like additional information
about other funds or classes of shares offered.

       With respect to matters that affect one class but not another,
shareholders vote as a class; for example, the approval of a Plan. Subject to
the foregoing, all shares of a Fund have equal voting rights and will be voted
in the aggregate, and not by series, except where voting by a series is required
by law or where the matter involved only affects one series. For example, a
change in a Fund's fundamental investment policy affects only one Series and
would be voted upon only by shareholders of the Fund involved. Additionally,
approval of an advisory contract since it affects only one Fund, is a matter to
be determined separately by each Series. Approval by the shareholders of one
Series is effective as to that Series whether or not sufficient votes are
received from the shareholders of the other Series to approve the proposal as to
those Series.

       As used in the Prospectus and in this SAI, the term "majority" when
referring to approvals to be obtained from shareholders of a Class of a Fund,
means the vote of the lesser of (i) 67% of the shares of such class of the Fund
represented at a meeting if the holders of more than 50% of the outstanding
shares of such Class Fund are present in person or by proxy, or (ii) more than
50% of the outstanding shares of such Class of the Fund. The term "majority,"
when referring to the approvals to be obtained from shareholders of the Company
as a whole, means the vote of the lesser of (i) 67% of the Company's shares
represented at a meeting if the holders of more than 50% of the Company's
outstanding shares are present in person or by proxy, or (ii) more than 50% of
the Company's outstanding shares.

       Shareholders are entitled to one vote for each full share held and
fractional votes for fractional shares held. Shareholders are not entitled to
any preemptive rights. All shares, when issued, will be fully paid and non-
assessable by the Company.

       The Company may dispense with an annual meeting of shareholders in any
year in which it is not required to elect directors under the 1940 Act.

       Each share of a class of a Fund represents an equal proportional interest
in the Fund with each other share in the same class and is entitled to such
dividends and distributions out of the

                                      33
<PAGE>
 
income earned on the assets belonging to the Fund as are declared in the
discretion of the Directors. In the event of the liquidation or dissolution of
the Company, shareholders of a Fund or class are entitled to receive the assets
attributable to the Fund or class that are available for distribution, and a
distribution of any general assets not attributable to a particular investment
portfolio that are available for distribution in such manner and on such basis
as the Directors in their sole discretion may determine.

       Set forth below as of October 31, 1997 is the name, address and share
ownership of each person known by the Company to have beneficial or record
ownership of 5% or more of a class of each Fund or 5% or more of the voting
securities of each Fund as a whole.

                                 SAI APPENDIX

       The following is a description of the ratings given by Moody's and S&P to
corporate and municipal bonds, municipal notes, and corporate and municipal
commercial paper.

Corporate and Municipal Bonds

       Moody's:  The four highest ratings for corporate and municipal bonds are
"Aaa," "Aa," "A" and "Baa."  Bonds rated "Aaa" are judged to be of the "best
quality" and carry the smallest amount of investment risk.  Bonds rated "Aa" are
of "high quality by all standards," but margins of protection or other elements
make long-term risks appear somewhat greater than "Aaa" rated bonds.  Bonds
rated "A" possess many favorable investment attributes and are considered to be
upper medium grade obligations.  Bonds rated "Baa" are considered to be medium
grade obligations; interest payments and principal security appear adequate for
the present, but certain protective elements may be lacking or may be
characteristically unreliable over any great length of time.  Such bonds have
speculative characteristics as well.  Moody's applies numerical modifiers:  1, 2
and 3 in each rating category from "Aa" through "Baa" in its rating system.  The
modifier 1 indicates that the security ranks in the higher end of its category;
the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that
the issue ranks in the lower end.

       S&P: The four highest ratings for corporate and municipal bonds are
"AAA," "AA," "A" and "BBB." Bonds rated "AAA" have the highest ratings assigned
by S&P and have an extremely strong capacity to pay interest and repay
principal. Bonds rated "AA" have a "very strong capacity to pay interest and
repay principal" and differ "from the highest rated issued only in small
degree." Bonds rated "A" have a "strong capacity" to pay interest and repay
principal, but are "somewhat more susceptible" to adverse effects of changes in
economic conditions or other circumstances than bonds in higher rated
categories. Bonds rated "BBB" are regarded as having an "adequate capacity" to
pay interest and repay principal, but changes in economic conditions or other
circumstances are more likely to lead to a "weakened capacity" to make such
repayments. The ratings from "AA" to "BBB" may be modified by the addition of a
plus or minus sign to show relative standing within the category.

Municipal Notes

       Moody's: The highest ratings for state and municipal short-term
obligations are "MIG 1," "MIG 2," and "MIG 3" (or "VMIG 1," "VMIG 2" and "VMIG
3" in the case of an issue having a variable rate demand feature). Notes rated
"MIG 1" or "VMIG 1" are judged to be of the "best quality." Notes rated "MIG 2"
or "VMIG 2" are of "high quality," with margins of protections "ample although
not as large as in the preceding group." Notes rated "MIG 3" or "VMIG 3" are of
"favorable quality," with all security elements accounted for, but lacking the
strength of the preceding grades.

       S&P:  The "SP-1" rating reflects a "very strong or strong capacity to pay
principal and interest."  Notes issued with "overwhelming safety
characteristics" will be rated "SP-1+."  The "SP-2" rating reflects a
"satisfactory capacity" to pay principal and interest.

                                      A-1
<PAGE>
 
Corporate and Municipal Commercial Paper

       Moody's: The highest rating for corporate and municipal commercial paper
is "P-1" (Prime-1). Issuers rated "P-1" have a "superior capacity for repayment
of short-term promissory obligations." Issuers rated "P-2" (Prime-2) "have a
strong capacity for repayment of short-term promissory obligations," but
earnings trends, while sound, will be subject to more variation.

     S&P: The "A-1" rating for corporate and municipal commercial paper
indicates that the "degree of safety regarding timely payment is either
overwhelming or very strong." Commercial paper with "overwhelming safety
characteristics" will be rated "A-1+." Commercial paper with a strong capacity
for timely payments on issues will be rated "A-2."

                                    GENERAL

   The Prime Money Market Mutual Fund operated as Pacific American Liquid
Assets, Inc. from commencement of operations on April 30, 1981, until it was
reorganized as a portfolio of Pacific American Fund on October 1, 1985. On
October 1, 1994, the Fund was reorganized as the Pacific American Money Market
Portfolio of Pacifica Funds Trust ("Pacifica"); and in July 1995, it was renamed
the Pacifica Prime Money Market Fund.

   Prior to August 1, 1990, the Treasury Money Market Mutual Fund was known as
the Short-Term Government Fund. The Treasury Money Market Mutual Fund operated
as a portfolio of Pacific American Fund through October 1, 1994, when it was
reorganized as the Pacific American U.S. Treasury Portfolio, a portfolio of
Pacifica Funds Trust. In July 1995, the Fund was renamed the Pacifica Treasury
Money Market Fund.

   On September 6, 1996, the Pacifica Prime Money Market Fund and Pacifica
Treasury Money Market Fund were reorganized as the Company's Prime Money Market
Mutual Fund and Treasury Money Market Mutual Fund, respectively.

                            INVESTMENT RESTRICTIONS


   Fundamental Investment Policies
   -------------------------------

   Each Fund has adopted the following investment restrictions, all of which are
fundamental policies; that is, they may not be changed without approval by the
vote of the holders of a majority (defined in the Investment Company Act of
1940, as amended (the "1940 Act")) of the outstanding voting securities of such
Fund.

The Prime Money Market Mutual and Treasury Money Market Mutual Funds may not:

   (1)  purchase common stocks and voting securities (including state, municipal
or industrial revenue bonds) except for securities of other investment
companies;

   (2)  borrow money or issue senior securities, except that each Fund may
borrow from banks or enter into reverse repurchase agreements for temporary
purposes in amounts up to one-third of the value of its total assets at the time
of such borrowing.  None of these Funds will purchase securities while its
borrowings (including reverse repurchase agreements) in excess of 5% of its
total assets are outstanding.  As a matter of non-fundamental policy, each Fund
intends to limit its investments in reverse repurchase agreements to no more
than 20% of its total assets;

   (3)  mortgage, pledge, or hypothecate any assets, except in connection with
any such borrowing and in amounts not in excess of one-third of the value of
each such Fund's total assets at the time of its borrowing. Securities held in
escrow or separate accounts in connection with a Fund's investment practices are
not deemed to be pledged for purposes of this investment restriction;

                                       1
<PAGE>
 
   (4)  purchase securities on margin, except for delayed delivery or when-
issued transactions or such short-term credits as are necessary for the
clearance of transactions; or make short sales of securities or, maintain a
short position;

   (5)  write put or call options;

   (6)  underwrite the securities of other issuers, except as each such Fund may
be deemed to be an underwriter in connection with the purchase or sale of
portfolio instruments in accordance with its investment objective and portfolio
management policies;

   (7)  invest in companies for the purpose of exercising control;

   (8)  make loans, except that each such Fund may purchase or hold debt
instruments in accordance with its investment objective and policies and may
enter into loans of portfolio securities and repurchase agreements;

   (9)  invest in securities of other investment companies, except as they may
be acquired as part of a merger, consolidation, acquisition of assets or where
otherwise permitted by the 1940 Act; nor

   (10) lend its portfolio securities in excess of one-third of the value of its
total assets.

   Non-Fundamental Investment Policies
   -----------------------------------

   Each Fund has adopted the following non-fundamental policies which may be
changed by a majority vote of the Board of Directors of the Company at any time
and without approval of such Fund's shareholders.

   (1)  Each Fund may invest in shares of other open-end management investment
companies, subject to the limitations of Section 12(d)(1) of the 1940 Act.
Under the 1940 Act, a Fund's investment in such securities currently is limited
to , subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5%  of such Fund's net assets with respect to any one
investment company, and (iii) 10% of such Fund's net assets in the aggregate.
Other investment companies in which the Funds invest can be expected to charge
fees for operating expenses, such as investment advisory and administration
fees, that would be in addition to those charged by a Fund.

   (2)  Each Fund may not invest more than 10% of its net assets in illiquid
securities.  For this purpose, illiquid securities include, among others, (a)
securities that are illiquid by virtue of the absence of a readily available
market or legal or contractual restrictions on resale, (b) fixed time deposits
that are subject to withdrawal penalties and that have maturities of more than
seven days, and (c) repurchase agreements not terminable within seven days.

   (3)  Each Fund may invest up to 25% of its net assets in securities of
foreign governmental and foreign private issuers that are denominated in and pay
interest in U.S. dollars.

                                       2
<PAGE>
 
   (4)  Each Fund may lend securities from its portfolios to brokers, dealers
and financial institutions, in amounts not to exceed (in the aggregate) one-
third of such Fund's total assets.  Any such loans of portfolio securities will
be fully collateralized based on values that are marked to market daily.  The
Funds will not enter into any portfolio security lending arrangement having a
duration of longer than one year.

                  ADDITIONAL PERMITTED INVESTMENT ACTIVITIES

   Set forth below are descriptions of certain investments and additional
investment policies for the Funds.

   Asset-Backed Securities
   -----------------------

   The Funds may purchase asset-backed securities, which are securities backed
by installment contracts, credit-card receivables or other assets.  Asset-backed
securities represent interests in "pools" of assets in which payments of both
interest and principal on the securities are made monthly, thus in effect
"passing through" monthly payments made by the individual borrowers on the
assets that underlie the securities, net of any fees paid to the issuer or
guarantor of the securities.  The average life of asset-backed securities varies
with the maturities of the underlying instruments and is likely to be
substantially less than the original maturity of the assets underlying the
securities as a result of prepayments.  For this and other reasons, an asset-
backed security's stated maturity may be shortened, and the security's total
return may be difficult to predict precisely.

   Bank Obligations
   ----------------

   The Funds may invest in bank obligations, including certificates of deposit,
time deposits, bankers' acceptances and other short-term obligations of domestic
banks, foreign subsidiaries of domestic banks, foreign branches of domestic
banks, and domestic and foreign branches of foreign banks, domestic savings and
loan associations and other banking institutions.  With respect to such
securities issued by foreign branches of domestic banks, foreign subsidiaries of
domestic banks, and domestic and foreign branches of foreign banks, a Fund may
be subject to additional investment risks that are different in some respects
from those incurred by a fund which invests only in debt obligations of U.S.
domestic issuers.  Such risks include possible future political and economic
developments, the possible imposition of foreign withholding taxes on interest
income payable on the securities, the possible establishment of exchange
controls or the adoption of other foreign governmental restrictions which might
adversely affect the payment of principal and interest on these securities and
the possible seizure or nationalization of foreign deposits.  In addition,
foreign branches of U.S. banks and foreign banks may be subject to less
stringent reserve requirements and to different accounting, auditing, reporting
and recordkeeping standards than those applicable to domestic branches of U.S.
banks.

   Certificates of deposit are negotiable certificates evidencing the obligation
of a bank to repay funds deposited with it for a specified period of time.

                                       3
<PAGE>
 
   Time deposits are non-negotiable deposits maintained in a banking institution
for a specified period of time at a stated interest rate.  Time deposits which
may be held by a Fund will not benefit from insurance from the Bank Insurance
Fund or the Savings Association Insurance Fund administered by the Federal
Deposit Insurance Corporation.  Bankers' acceptances are credit instruments
evidencing the obligation of a bank 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 face amount of the instrument upon maturity.  The other short-term
obligations may include uninsured, direct obligations, bearing fixed, floating-
or variable-interest rates.

   Commercial Paper
   ----------------

   The Funds may invest in commercial paper. Commercial paper includes short-
term unsecured promissory notes, variable rate demand notes and variable rate
master demand notes issued by domestic and foreign bank holding companies,
corporations and financial institutions as well as similar taxable instruments
issued by government agencies and instrumentalities.

   Floating- and Variable-Rate Obligations
   ---------------------------------------

   The Funds may purchase floating- and variable-rate obligations.  Each Fund
may purchase floating- and variable-rate demand notes and bonds.  These
obligations may have stated maturities in excess of thirteen months, but they
permit the holder to demand payment of principal at any time, or at specified
intervals not exceeding thirteen months.  Variable-rate demand notes include
master demand notes that are obligations that permit a Fund to invest
fluctuating amounts, which may change daily without penalty, pursuant to direct
arrangements between the Fund, as lender, and the borrower.  The interest rates
on these notes may fluctuate from time to time.  The issuer of such obligations
ordinarily has a corresponding right, after a given period, to prepay in its
discretion the outstanding principal amount of the obligations plus accrued
interest upon a specified number of days' notice to the holders of such
obligations.  The interest rate on a floating-rate demand obligation is based on
a known lending rate, such as a bank's prime rate, and is adjusted automatically
each time such rate is adjusted.  The interest rate on a variable-rate demand
obligation is adjusted automatically at specified intervals.  Frequently, such
obligations are secured by letters of credit or other credit support
arrangements provided by banks.  Because these obligations are direct lending
arrangements between the lender and borrower, it is not contemplated that such
instruments generally will be traded, and there generally is no established
secondary market for these obligations, although they are redeemable at face
value.  Accordingly, where these obligations are not secured by letters of
credit or other credit support arrangements, a Fund's right to redeem is
dependent on the ability of the borrower to pay principal and interest on
demand.  Such obligations frequently are not rated by credit rating agencies and
each Fund may invest in obligations which are not so rated only if Wells Fargo
Bank determines that at the time of investment the obligations are of comparable
quality to the other obligations in which such Fund may invest.  Wells Fargo
Bank, on behalf of each Fund, considers on an ongoing basis the creditworthiness
of the issuers of the floating- and variable-rate demand obligations in such
Fund's portfolio.  No Fund will invest more than 10% of the value of its total
net assets in floating- or variable-rate demand obligations whose demand feature

                                       4
<PAGE>
 
is not exercisable within seven days. Such obligations may be treated as liquid,
provided that an active secondary market exists.

   Foreign Obligations
   -------------------

   Each Fund may invest up to 25% of its assets in high-quality, short-term
(thirteen months or less) debt obligations of foreign branches of U.S. banks or
U.S. branches of foreign banks that are denominated in and pay interest in U.S.
dollars.  Investments in foreign obligations involve certain considerations that
are not typically associated with investing in domestic obligations.  There may
be less publicly available information about a foreign issuer than about a
domestic issuer.  Foreign issuers also are not subject to the same uniform
accounting, auditing and financial reporting standards or governmental
supervision as domestic issuers.  In addition, with respect to certain foreign
countries, taxes may be withheld at the source under foreign income tax laws and
there is a possibility of expropriation or confiscatory taxation, political or
social instability, or diplomatic developments that could affect adversely
investments in, the liquidity of, and the ability to enforce contractual
obligations with respect to, securities of issuers located in those countries.

   Forward Commitments, When-Issued Purchases and Delayed-Delivery Transactions
   ----------------------------------------------------------------------------

   Each Fund may purchase or sell securities on a when-issued or delayed-
delivery basis and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. Securities purchased or
sold on a when-issued, delayed-delivery or forward commitment basis involve a
risk of loss if the value of the security to be purchased declines, or the value
of the security to be sold increases, before the settlement date.  Although each
Fund will generally purchase securities with the intention of acquiring them, a
Fund may dispose of securities purchased on a when-issued, delayed-delivery or a
forward commitment basis before settlement when deemed appropriate by the
adviser.

   Each Fund will segregate cash, U.S. Government obligations or other high-
quality debt instruments in an amount at least equal in value to the Fund's
commitments to purchase when-issued securities.  If the value of these assets
declines, the Fund will segregate additional liquid assets on a daily basis so
that the value of the segregated assets is equal to the amount of such
commitments.

   Illiquid Securities
   -------------------

   The Funds may invest in securities not registered under the 1933 Act and
other securities subject to legal or other restrictions on resale.  Because such
securities may be less liquid than other investments, they may be difficult to
sell promptly at an acceptable price.  Delay or difficulty in selling securities
may result in a loss or be costly to a Fund.  Each Fund may invest up to 10% of
its assets in net illiquid securities.

                                       5
<PAGE>
 
   Letters of Credit
   -----------------

   Certain of the debt obligations (including municipal securities, certificates
of participation, commercial paper and other short-term obligations) which the
Funds may purchase may be backed by an unconditional and irrevocable letter of
credit of a bank, savings and loan association or insurance company which
assumes the obligation for payment of principal and interest in the event of
default by the issuer.  Only banks, savings and loan associations and insurance
companies which, in the opinion of Wells Fargo Bank, are of comparable quality
to issuers of other permitted investments of each such Fund may be used for
letter of credit-backed investments.

   Loans of Portfolio Securities
   -----------------------------

   The Funds may lend their portfolio securities to brokers, dealers and
financial institutions, provided:  (1) the loan is secured continuously by
collateral consisting of U.S. Government securities or cash or letters of credit
maintained on a daily marked-to-market basis in an amount at least equal to the
current market value of the securities loaned; (2) the Funds may at any time
call the loan and obtain the return of the securities loaned within five
business days; (3) the Funds will receive any interest or dividends paid on the
loaned securities; and (4) the aggregate market value of securities loaned will
not at any time exceed one third of the total assets of a particular Fund.

   A Fund will earn income for lending its securities because cash collateral
pursuant to such loans will be invested in short-term money market instruments.
In connection with lending securities, the Funds may pay reasonable finders,
administrative and custodial fees.  A Fund will not enter into any security
lending arrangement having a duration longer than one year.  Loans of securities
involve a risk that the borrower may fail to return the securities or may fail
to provide additional collateral. In either case, a Fund could experience delays
in recovering securities or collateral or could lose all or part of the value of
the loaned securities.  When a Fund lends its securities, it continues to
receive interest or dividends on the securities loaned and may simultaneously
earn interest on the collateral received from the borrower or from the
investment of cash collateral in readily marketable, high-quality, short-term
obligations. Although voting rights, or rights to consent, attendant to
securities on loan pass to the borrower, such loans may be called at any time
and will be called so that the securities may be voted by a Fund if a material
event affecting the investment is to occur.  A Fund may pay a portion of the
interest and fees earned from securities lending to a borrower or a placing
broker.  Borrowers and placing brokers may not be affiliated, directly or
indirectly, with Wells Fargo Bank, Stephens Inc. or any of their affiliates.

   Mortgage-Backed Securities
   --------------------------

   The Funds may invest in mortgage-backed securities, including those
representing an undivided ownership interest in a pool of mortgages, such as
certificates of the Government National Mortgage Association ("GNMA") and the
Federal Home Loan Mortgage Corporation ("FHLMC"). These certificates are in most
cases pass-through instruments, through which the holder receives a share of all
interest and principal payments from the mortgages underlying the certificate,
net of certain fees.  The average life of a mortgage-backed security varies with
the underlying mortgage instruments, which generally have maximum maturities of
40 years. The 

                                       6
<PAGE>
 
average life is likely to be substantially less than the original maturity of
the mortgage pools underlying the securities as the result of prepayments,
mortgage refinancings or foreclosure. Mortgage prepayment rates are affected by
factors including the level of interest rates, general economic conditions, the
location and age of the mortgage and other social and demographic conditions.
Such prepayments are passed through to the registered holder with the regular
monthly payments of principal and interest and have the effect of reducing
future payments.

   There are risks inherent in the purchase of mortgage-backed securities. For
example, these securities are subject to a risk that default in payment will
occur on the underlying mortgages. In addition to default risk, these securities
are subject to the risk that prepayment on the underlying mortgages will occur
earlier or later or at a lesser or greater rate than expected. To the extent
that adviser's assumptions about prepayments are inaccurate, these securities
may expose the Funds, to significantly greater market risks than expected.

   Municipal Bonds
   ---------------

   The Prime Money Market Mutual Fund may invest in municipal bonds.  The two
principal classifications of municipal bonds are "general obligation" and
"revenue" bonds.  Municipal bonds are debt obligations issued to obtain funds
for various public purposes, including the construction of a wide range of
public facilities such as bridges, highways, housing, hospitals, mass
transportation, schools, streets, and water and sewer works.  Other purposes for
which municipal bonds may be issued include the refunding of outstanding
obligations and obtaining funds for general operating expenses or to loan to
other public institutions and facilities.  Industrial development bonds are a
specific type of revenue bond backed by the credit and security of a private
user.  Certain types of industrial development bonds are issued by or on behalf
of public authorities to obtain funds to provide privately-operated housing
facilities, sports facilities, convention or trade show facilities, airport,
mass transit, port or parking facilities, air or water pollution control
facilities and certain local facilities for water supply, gas, electricity, or
sewage or solid waste disposal.  The Fund may not invest 25% or more of its
assets in industrial development bonds.  Assessment bonds, wherein a specially
created district or project area levies a tax (generally on its taxable
property) to pay for an improvement or project may be considered a variant of
either category.  There are, of course, other variations in the types of
municipal bonds, both within a particular classification and between
classifications, depending on numerous factors.

   The [TREASURY MONEY MARKET MUTUAL] Fund may invest in municipal lease
obligations.  Wells Fargo Bank makes determinations concerning the liquidity of
a municipal lease obligation based on factors deemed relevant.  These factors
may include, among others: (1) the frequency of trades and quotes for the
obligation; (2) the number of dealers willing to purchase or sell the security
and the number of other potential buyers; (3) the willingness of dealers to
undertake to make a market in the security; and (4) the nature of the
marketplace trades, including the time needed to dispose of the security, the
method of soliciting offers, and the mechanics of transfer. In addition, the
general credit quality of the municipality and the essentiality to the
municipality of the property covered by the lease may be considered. In
evaluating the credit quality of a municipal lease obligation, the factors to be
considered might include:  (1) whether the lease can be canceled; 

                                       7
<PAGE>
 
(2) what assurance there is that the assets represented by the lease can be
sold; (3) the strength of the lessee's general credit (e.g., its debt,
administrative, economic, and financial characteristics); (4) the likelihood
that the municipality will discontinue appropriating funding for the leased
property because the property is no longer deemed essential to the operations of
the municipality (e.g., the potential for an "event of the nonappropriation");
and (5) the legal recourse in the event of failure to appropriate.

   From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on municipal obligations. For example, under federal tax legislation
enacted in 1986, interest on certain private activity bonds must be included in
an investor's alternative minimum taxable income, and corporate investors must
treat all tax-exempt interest as an item of tax preference.  Opinions relating
to the validity of municipal obligations and to the exemption of interest
thereon from federal income tax are rendered by bond counsel to the respective
issuers at the time of issuance. Neither the Funds nor the adviser will review
the proceedings relating to the issuance of municipal obligations or the basis
for such opinions.

   Certain of the municipal obligations held by a Fund may be insured as to the
timely payment of principal and interest. The insurance policies usually are
obtained by the issuer of the municipal obligation at the time of its original
issuance. In the event that the issuer defaults on interest or principal
payment, the insurer will be notified and will be required to make payment to
the bondholders. There is, however, no guarantee that the insurer will meet its
obligations. In addition, such insurance does not protect against market
fluctuations caused by changes in interest rates and other factors.

   The values of outstanding municipal securities will vary as a result of
changing market evaluations of the ability of their issuers to meet the interest
and principal payments (i.e., credit risk).  Such values also will change in
response to changes in the interest rates payable on new issues of municipal
securities (i.e., market risk).  Should such interest rates rise, the values of
outstanding securities, including those held in a Fund's portfolio, will decline
and (if purchased at par value) sell at a discount.  If interests rates fall,
the values of outstanding securities will generally increase and (if purchased
at par value) sell at a premium.  Changes in the value of municipal securities
held in the Fund's portfolio arising from these or other factors will cause
changes in the net asset value per share.

   Other Investment Companies
   --------------------------

   The Funds may invest in shares of other open-end management investment
companies, up to the limits prescribed in Section 12(d) of the 1940 Act.  Under
the 1940 Act, a Fund's investment in such securities currently is limited to,
subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5% of such Fund's net assets with respect to any one
investment company and (iii) 10% of such Fund's net assets in aggregate.  Other
investment companies in which the Funds invest can be expected to charge fees
for operating expenses such as investment advisory and administration fees, that
would be in addition to those charged by the Funds.

                                       8
<PAGE>
 
   Repurchase Agreements
   ---------------------

   Each Fund may enter into repurchase agreements, wherein the seller of a
security to the Fund agrees to repurchase that security from the Fund at a
mutually agreed upon time and price.  A Fund may enter into repurchase
agreements only with respect to securities that could otherwise be purchased by
the Fund.  All repurchase agreements will be fully collateralized at 102% based
on values that are marked to market daily.  The maturities of the underlying
securities in a repurchase agreement transaction may be greater than twelve
months, although the maximum term of a repurchase agreement will always be less
than twelve months.  If the seller defaults and the value of the underlying
securities has declined, a Fund may incur a loss.  In addition, if bankruptcy
proceedings are commenced with respect to the seller of the security, the Fund's
disposition of the security may be delayed or limited.

   Each Fund may not enter into a repurchase agreement with a maturity of more
than seven days, if, as a result, more than 10% of the market value of such
Fund's total net assets would be invested in repurchase agreements with
maturities of more than seven days, restricted securities and illiquid
securities.  A Fund will only enter into repurchase agreements with primary
broker/dealers and commercial banks that meet guidelines established by the
Board of Directors and that are not affiliated with the investment adviser.  The
Funds may participate in pooled repurchase agreement transactions with other
funds advised by Wells Fargo Bank.

   Borrowing and Reverse Repurchase Agreements
   -------------------------------------------

   The Funds intend to limit their borrowings (including reverse repurchase
agreements) during the current fiscal year to not more than 10% of their net
assets.  At the time a Fund enters into a reverse repurchase agreement (an
agreement under which the Fund sells portfolio securities and agrees to
repurchase them at an agreed-upon date and price), it will place in a segregated
custodial account liquid assets such as U.S. Government securities or other
liquid high-grade debt securities having a value equal to or greater than the
repurchase price (including accrued interest) and will subsequently monitor the
account to ensure that such value is maintained. Reverse repurchase agreements
involve the risk that the market value of the securities sold by a Fund may
decline below the price at which the Fund is obligated to repurchase the
securities. Reverse repurchase agreements are considered to be borrowings under
the 1940 Act.

   Unrated and Downgraded Investments
   ----------------------------------

   The Funds may purchase instruments that are not rated if, in the opinion of
Wells Fargo Bank the investment adviser, such obligations are of comparable
quality to other rated investments that are permitted to be purchased by the
Fund.  The Fund may purchase unrated instruments only if they are purchased in
accordance with the Fund's procedures adopted by Company's Board of Directors in
accordance with Rule 2a-7 under the 1940 Act.  After purchase by the Fund, a
security may cease to be rated or its rating may be reduced below the minimum
required for purchase by the Fund.  In the event that a portfolio security
ceases to be an "Eligible Security" or no longer "presents minimal credit
risks," immediate sale of such security is not required, provided that the Board
of Directors has determined that disposal of the portfolio security would not be
in the best interests of the Fund.  To the extent the ratings given by 

                                       9
<PAGE>
 
Moody's or S&P may change as a result of changes in such organizations or their
rating systems, the Fund will attempt to use comparable ratings as standards for
investments in accordance with the investment policies. The ratings of Moody's
and S&P are more fully described in the Appendix.

   U.S. Government and U.S. Treasury Obligations
   ---------------------------------------------

   The Funds may invest in obligations of agencies and instrumentalities of the
U.S. Government ("U.S. Government obligations").  The Treasury Money Market
Mutual Fund may invest only in U.S. Government obligations issued or guaranteed
by the U.S. Treasury.  Payment of principal and interest on U.S. Government
obligations (i) may be backed by the full faith and credit of the United States
(as with U.S. Treasury bills and GNMA certificates) or (ii) may be backed solely
by the issuing or guaranteeing agency or instrumentality itself (as with FNMA
notes).  In the latter case investors must look principally to the agency or
instrumentality issuing or guaranteeing the obligation for ultimate repayment,
which agency or instrumentality may be privately owned.  There can be no
assurance that the U.S. Government will provide financial support to its
agencies or instrumentalities where it is not obligated to do so.  In addition,
U.S. Government obligations are subject to fluctuations in market value due to
fluctuations in market interest rates.  As a general matter, the value of debt
instruments, including U.S. Government obligations, declines when market
interest rates increase and rises when market interest rates decrease.  Certain
types of U.S. Government obligations are subject to fluctuations in yield or
value due to their structure or contract terms.

   The Treasury Money Market Mutual Fund may invest only in obligations issued
or guaranteed by the U.S. Treasury such as bills, notes, bonds and certificates
of indebtedness, and in notes and repurchase agreements collateralized or
secured by such obligations ("U.S. Treasury obligations").  U.S. Treasury notes,
bills and bonds differ mainly in the length of their maturity.  The U.S.
Treasury obligations in which the Fund invests may also include "U.S. Treasury
STRIPS," interests in U.S. Treasury obligations reflected in the Federal
Reserve-Book Entry System that represent ownership in either the future interest
payments or the future principal payments on the U.S. Treasury obligations.
U.S. Treasury Strips are "stripped securities."  Stripped securities are issued
at a discount to their face value and may exhibit greater price volatility than
ordinary debt securities because of the manner in which their principal and
interest are paid to investors.  The Treasury Money Market Mutual and Government
Money Market Mutual Funds may invest in U.S. Treasury STRIPS.

   The Funds may attempt to increase yields by trading to take advantage of
short-term market variations.  This policy could result in high portfolio
turnover, which should not adversely affect the Funds since they do not
ordinarily pay brokerage commissions on the purchase of short-term debt
obligations.

   Nationally Recognized Statistical Ratings Organizations
   -------------------------------------------------------

   The ratings of Moody's Investors Service, Inc., Standard & Poor's Ratings
Group, Duff & Phelps Credit Rating Co., Fitch Investors Service, Inc., Thomson
Bank Watch and IBCA Inc. represent their opinions as to the quality of debt
securities. It should be emphasized, however, that 

                                      10
<PAGE>
 
ratings are general and not absolute standards of quality, and debt securities
with the same maturity, interest rate and rating may have different yields while
debt securities of the same maturity and interest rate with different ratings
may have the same yield. Subsequent to purchase by a Fund, an issue of debt
securities may cease to be rated or its rating may be reduced below the minimum
rating required for purchase by a Fund. The adviser will consider such an event
in determining whether the Fund involved should continue to hold the obligation.

   The payment of principal and interest on debt securities purchased by the
Funds depends upon the ability of the issuers to meet their obligations. An
issuer's obligations under its debt securities are subject to the provisions of
bankruptcy, insolvency, and other laws affecting the rights and remedies of
creditors, such as the Federal Bankruptcy Code, and laws, if any, which may be
enacted by federal or state legislatures extending the time for payment of
principal or interest, or both, or imposing other constraints upon enforcement
of such obligations or, in the case of governmental entities, upon the ability
of such entities to levy taxes. The power or ability of an issuer to meet its
obligations for the payment of interest and principal of its debt securities may
be materially adversely affected by litigation or other conditions. Further, it
should also be noted with respect to all municipal obligations issued after
August 15, 1986 (August 31, 1986 in the case of certain bonds), the issuer must
comply with certain rules formerly applicable only to industrial development
bonds which, if the issuer fails to observe them, could cause interest on the
municipal obligations to become taxable retroactive to the date of issue.

                                 RISK FACTORS

   Investments in a Fund are not bank deposits or obligations of Wells Fargo
Bank, are not insured by the FDIC and are not insured or guaranteed against loss
of principal.  Therefore, you should be willing to accept some risk with money
you invest in a Fund. Although the Funds seek to maintain a stable net asset
value of $1.00 per share, there is no assurance that they will be able to do so.
The Funds may not achieve as high a level of current income as other mutual
funds that do not limit their investment to the high credit quality instruments
in which the Funds invest.  As with all mutual funds, there can be no assurance
that a Fund will achieve its investment objective.

   The Funds, under the 1940 Act, must comply with certain investment criteria
designed to provide liquidity, reduce risk, and allow the Funds to maintain a
stable net asset value of $1.00 per share.  The Funds' dollar-weighted average
portfolio maturity must not exceed 90 days.  Any security that a Fund purchases
must have a remaining maturity of not more than 397 days (13 months).  In
addition, any security that a Fund purchases must present minimal credit risks
and be of "high quality," or in the case of the Treasury Money Market Mutual
Fund, be of the "highest quality."  "High quality" means to be rated in the top
two rating categories and "highest quality" means to be rated only in the top
rating category, by the requisite NRSROs or, if unrated, determined to be of
comparable quality to such rated securities by Wells Fargo Bank, as the Funds'
investment adviser, under guidelines adopted by the Board of Directors of the
Company.

                                      11
<PAGE>
 
   Each Fund seeks to reduce risk by investing its assets in securities of
various issuers.  In addition, the Funds emphasize safety of principal and high
credit quality.  In particular, the internal investment policies of the
investment adviser prohibit the purchase of many types of floating-rate
derivative securities that are considered potentially volatile.  The following
types of derivative securities ARE NOT permitted investments for the Funds:

          .    capped floaters (on which interest is not paid when market rates
               move above a certain level);

          .    leveraged floaters (whose interest rate reset provisions are
               based on a formula that magnifies changes in interest rates);

          .    range floaters (which do not pay any interest if market interest
               rates move outside of a specified range);

          .    dual index floaters (whose interest rate reset provisions are
               tied to more than one index so that a change in the relationship
               between these indices may result in the value of the instrument
               falling below face value); and

          .    inverse floaters (which reset in the opposite direction of their
               index).

     Additionally, the Funds may not invest in securities whose interest rate
reset provisions are tied to an index that materially lags short-term interest
rates, such as Cost of Funds Index floaters.  The Funds may invest only in
variable or floating-rate securities that bear interest at a rate that resets
quarterly or more frequently and that resets based on changes in standard money
market rate indices such as U.S. Treasury bills, London Interbank Offered Rate
or LIBOR, the prime rate, published commercial paper rates, federal funds rates,
Public Securities Associates floaters or JJ Kenney index floaters.

     The Treasury Money Market Mutual Fund restricts its investment to U.S.
Treasury obligations that meet all of the standards described above.
Obligations issued or guaranteed by the U.S. Treasury have historically involved
little risk of loss of principal if held to maturity.  However, due to
fluctuations in interest rates, the market value of such obligations may vary
during the period a shareholder owns shares of the Fund.  It should be noted
that neither the United States, nor any agency or instrumentality thereof, has
guaranteed, sponsored or approved the Fund or its shares.

     The portfolio debt instruments of the Funds are subject to credit and
interest-rate risk. Credit risk is the risk that issuers of the debt instruments
in which the Funds invest may default on the payment of principal and/or
interest.  Interest-rate risk is the risk that increases in market interest
rates may adversely affect the value of the debt instruments in which the Funds
invest and hence the value of your investment in a Fund.

     Generally, securities in which the Funds invest will not earn as high a
yield as securities of longer maturity and/or of lesser quality that are more
subject to market volatility.  Each Fund 

                                      12
<PAGE>
 
attempts to maintain the value of its shares at a constant $1.00 per share,
although there can be no assurance that a Fund will always be able to do so.

   Directors of the Company are compensated annually by the Company and by all
the registrants in each fund complex they serve as indicated above and also are
reimbursed for all out-of-pocket expenses relating to attendance at board
meetings. The Company, Stagecoach Trust and Life & Annuity Trust are considered
to be members of the same fund complex as such term is defined in Form N-1A
under the 1940 Act (the "Wells Fargo Fund Complex"). Overland Express Funds,
Inc. and Master Investment Trust, two investment companies previously advised by
Wells Fargo Bank, were part of the Wells Fargo Fund Complex prior to December
12, 1997. These companies are no longer part of the Wells Fargo Fund Complex.
MasterWorks Funds Inc., Master Investment Portfolio, and Managed Series
Investment Trust together form a separate fund complex (the "BGFA Fund
Complex"). Each of the Directors and Officers of the Company serves in the
identical capacity as directors and officers or as trustees and/or officers of
each registered open-end management investment company in both the Wells Fargo
and BGFA Fund Complexes, except for Joseph N. Hankin, who only serves the
aforementioned members of the Wells Fargo Fund Complex. The Directors are
compensated by other companies and trusts within a fund complex for their
services as directors/trustees to such companies and trusts. Currently the
Directors do not receive any retirement benefits or deferred compensation from
the Company or any other member of each fund complex.

   As of the date of this SAI, Directors and Officers of the Company as a group
beneficially owned less than 1% of the outstanding shares of the Company.

   INVESTMENT ADVISER.  Wells Fargo Bank provides investment advisory services
   -------------------                                               
to the Funds. As investment adviser, Wells Fargo Bank furnishes investment
guidance and policy direction in connection with the daily portfolio management
of the Funds. Wells Fargo Bank furnishes to the Company's Board of Directors
periodic reports on the investment strategy and performance of each Fund. Wells
Fargo Bank provides the Funds with, among other things, money market and fixed-
income research, analysis and statistical and economic data and information
concerning interest rate and securities markets trends, portfolio composition,
and credit conditions.

   As compensation for its advisory services, Well Fargo Bank is entitled to
receive a monthly fee at the annual rate of 0.25% of each Fund's average daily
net assets.

   For the period indicated below, the Funds paid to Wells Fargo Bank the
following advisory fees and Wells Fargo Bank waived the indicated amounts:

   The Pacifica Prime Money Market and Treasury Money Market Funds were
reorganized as the Company's Prime Money Market Mutual and Treasury Money Market
Mutual Funds on September 6, 1996.  Prior to September 6, 1996, Wells Fargo
Investment Management, Inc. ("WFIM") and its predecessor, First Interstate
Capital Management, Inc. ("FICM") served as adviser to the Pacifica Prime Money
Market and Treasury Money Market Funds.  As of September 6, 1996, Wells Fargo
Bank became the adviser to the Company's Prime Money Market Mutual and Treasury
Money Market Mutual Funds.

   For the period begun April 1, 1996 and ended September 5, 1996 the
predecessor portfolios paid to WFIM, and for the period begun September 6, 1996
and ended September 30, 1996, the Funds paid to Wells Fargo Bank the advisory

operation of such Funds, pursuant to an Administrative Services Contract.  For
these services, Furman Selz was entitled to receive a fee, payable monthly, at
the annual rate of 0.15% of the average daily net assets of the predecessor
portfolios.

   The predecessor portfolios of the Prime Money Market Mutual and Treasury
Money Market Mutual Funds were administered through April 21, and April 14,
1996, respectively, by the Dreyfus Corporation ("Dreyfus"), at the annual rate
of 0.10% of each such Fund's average daily net assets.

   SHAREHOLDER SERVICING AGENT.  The Funds have approved a Servicing Plan and
   ---------------------------
have entered into related shareholder servicing agreements, on behalf of the
Service Class shares, with financial institutions, including Wells Fargo Bank.
Under the agreements, Shareholder Servicing Agents (including Wells Fargo Bank)
agree to perform, as agents for their customers, administrative services, with
respect to Fund shares, which include aggregating and transmitting shareholder
orders for purchases, exchanges and redemptions; maintaining shareholder
accounts and records; and providing such other related services as the Company
or a shareholder may reasonably request. For providing shareholder services, a
Servicing Agent is entitled to a fee from the applicable Fund, not to exceed
0.20%, on an annualized basis, of the average daily net assets of the class of
shares owned of record or beneficially by the customers of the Servicing Agent
during the period for which payment is being made. The Servicing Plans and
related forms of shareholder servicing agreements were approved by the Company's
Board of Directors and provide that a Fund shall not be obligated to make any
payments under such Plans or related Agreements that exceed

                                      18

such continuance is approved by a majority vote of both the Directors of the
Company, including a majority of the Directors who are not "interested persons"
(as defined in the 1940 Act) of the Funds ("Non-Interested Directors").  Any
form of servicing agreement related to a Servicing Plan also must be approved by
such vote of the Directors and the Non-Interested Directors.  Servicing
Agreements may be terminated at any time, without payment of any penalty, by
vote of a majority of the Board of Directors, including a majority of the Non-
Interested Directors.  No material amendment to the Servicing Plans or related
Servicing Agreements may be made except by a majority of both the Directors of
the Company and the Non-Interested Directors.

   Each Servicing Plan requires that the Administrator shall provide to the
Directors, and the Directors shall review, at least quarterly, a written report
of the amounts expended (and purposes therefor) under the Servicing Plan.

   Under the transfer agency agreement for the Service Class shares of the Funds
in effect prior to February 1, 1997, Wells Fargo Bank was entitled to receive
monthly payments at the annual rate of 0.02% of the average daily net assets of
the Service Class shares of each Fund, as well as reimbursement for all
reasonable out-of-pocket expenses.  Furman Selz acted as Transfer Agent for the
predecessor portfolios. Pacifica compensated Furman Selz for providing personnel
and facilities to perform transfer agency related services for Pacifica at a
rate intended to represent the cost of providing such services.

   UNDERWRITING COMMISSIONS.  The Service Class of each Fund does not charge any
   ------------------------                                                     
front-end sales loads or contingent-deferred sales charges in connection with
the purchase and redemption of its shares, and therefore pays no underwriting
commissions to the Distributor.

                            PERFORMANCE CALCULATIONS

   The Funds may advertise certain yield and total return information.
Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown.  Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.

   In connection with communicating its performance to current or prospective
shareholders, these figures may also be compared to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

   Performance information for a Fund or Class of shares in a Fund may be useful
in reviewing the performance of such Fund or Class of shares and for providing a
basis for comparison with investment alternatives.  The yield of a Fund and the
yield of a Class of shares in a Fund, however, may not be comparable to the
yields from investment alternatives because of differences in the foregoing
variables and differences in the methods used to value portfolio securities,
compute expenses and calculate yield.

   TOTAL RETURN:  The Funds may advertise certain total return information
   ------------                                                           
computed in the manner described in the Prospectus.  As and to the extent
required by the SEC, an average annual compound rate of return ("T") is computed
by using the redeemable value at the end of a specified period ("ERV") of a
hypothetical initial investment ("P") over a period of years ("n") according to
the following formula:  P(1+T)n=ERV.  In addition, as indicated in each
Prospectus, each Fund also may, at times, calculate total return based on net
asset value per share (rather than the public offering price), in which case the
figures would not reflect the effect of any sales charges that would have been
paid by an investor, or based on the assumption that a sales charge 

                                      21
<PAGE>
 
other than the maximum sales charge (reflecting a Volume Discount) was assessed,
provided that total return data derived pursuant to the calculation described
above also are presented.

   Performance information may be advertised for non-standardized periods,
including year-to-date and other periods less than a year for the Funds.

   In addition to the above performance information, each Fund may also
advertise the cumulative total return of the Fund.  Cumulative total return is
based on the overall percentage change in value of a hypothetical investment in
the Fund, assuming all Fund dividends and capital gain distributions are
reinvested, without reflecting the effect of any sales charge that would be paid
by an investor, and is not annualized.

   ------------------                                                          
tax-equivalent yields (if applicable) and effective yields in advertisements or
reports to shareholders or prospective investors.  Quotations of yield for the
Funds are based on the investment income per share earned during a particular
seven-day or thirty-day period, less expenses accrued during a period ("net
investment income") and are computed by dividing net investment income by the
offering price per share on the last date of the period, according to the
following formula:

                          YIELD - 2[(a - b + 1)/6/ -1]
                                     -----            
                                       Cd
                                        
   where a = dividends and interest earned during the period, b = expenses
accrued for the period (net of any reimbursements), c = the average daily number
of shares outstanding during the period that were entitled to receive dividends,
and d = the maximum offering price per share on the last day of the period.

   EFFECTIVE YIELD:  Effective yields for the Funds are based on the change in
   ---------------                                                            
the value of a hypothetical investment (exclusive of capital changes) over a
particular seven-day (or thirty-day) period, less a pro-rata share of each
Fund's expenses accrued over that period (the "base period"), and stated as a
percentage of the investment at the start of the base period (the "base 

                                      22
<PAGE>
 
period return"). The base period return is then annualized multiplying by 365/7
(or 365/30 for thirty-day yield), with the resulting yield figure carried to at
least the nearest hundredth of one percent. "Effective yield" for the Funds
assumes that all dividends received during the period have been reinvested.
Calculation of "effective yield" begins with the same "base period return" used
in the calculation of yield, which is then annualized to reflect weekly
compounding pursuant to the following formula:

         Effective Seven-Day Yield = [(Base Period Return +1)365/7]-1.

   From time to time and only to the extent the comparison is appropriate for a
Fund or a Class of shares, the Company may quote the performance or price-
earning ratio of a Fund or Class in advertising and other types of literature as
compared to the performance of the S&P Index, the Dow Jones Industrial Average,
the Lehman Brothers 20+ Treasury Index, the Lehman Brothers 5-7 Year Treasury
Index, Donoghue's Money Fund Averages, Real Estate Investment Averages (as
reported by the National Association of Real Estate Investment Trusts), Gold
Investment Averages (provided by World Gold Council), Bank Averages (which are
calculated from figures supplied by the U.S. League of Savings Institutions
based on effective annual rates of interest on both passbook and certificate
accounts), average annualized certificate of deposit rates (from the Federal
Reserve G-13 Statistical Releases or the Bank Rate Monitor), the Salomon One
Year Treasury Benchmark Index, the Consumer Price Index (as published by the
U.S. Bureau of Labor Statistics), other managed or unmanaged indices or
performance data of bonds, municipal securities, stocks or government securities
(including data provided by Ibbotson Associates), or by other services,
companies, publications or persons who monitor mutual funds on overall
performance or other criteria.  The S&P Index and the Dow Jones Industrial
Average are unmanaged indices of selected common stock prices.  The performance
of the Funds or a Class also may be compared to that of other mutual funds
having similar objectives.  This comparative performance could be expressed as a
ranking prepared by Lipper Analytical Services, Inc., CDA Investment
Technologies, Inc., Bloomberg Financial Markets or Morningstar, Inc.,
independent services which monitor the performance of mutual funds.  The Funds'
performance will be calculated by relating net asset value per share at the
beginning of a stated period to the net asset value of the investment, assuming
reinvestment of all gains distributions and dividends paid, at the end of the
period.  The Funds' comparative performance will be based on a comparison of
yields, as described above, or total return, as reported by Lipper, Survey
Publications, Donoghue or Morningstar, Inc.

                                      23

   Any such comparisons may be useful to investors who wish to compare past
performance of the Funds or a Class with that of competitors.  Of course, past
performance cannot be a guarantee of future results.  The Company also may
include, from time to time, a reference to certain marketing approaches of the
Distributor, including, for example, a reference to a potential shareholder
being contacted by a selected broker or dealer.  General mutual fund statistics
provided by the Investment Company Institute may also be used.

   The Company also may use the following information in advertisements and
other types of literature, only to the extent the information is appropriate for
the Fund:  (i) the Consumer Price Index may be used to assess the real rate of
return from an investment in a Fund; (ii) other government statistics,
including, but not limited to, The Survey of Current Business, may be used to
illustrate investment attributes of a Fund or the general economic, business,
investment, or financial environment in which a Fund operates; (iii) the effect
of tax-deferred compounding on the investment returns of a Fund, or on returns
in general, may be illustrated by graphs, charts, etc., where such graphs or
charts would compare, at various points in time, the return from an investment
in a Fund (or returns in general) on a tax-deferred basis (assuming reinvestment
of capital gains and dividends and assuming one or more tax rates) with the
return on a taxable basis; and (iv) the sectors or industries in which a Fund
invests may be compared to relevant indices of stocks or surveys (e.g., S&P
Industry Surveys) to evaluate a Fund's historical performance or current or
potential value with respect to the particular industry or sector.

   In addition, the Company also may use, in advertisements and other types of
literature, information and statements: (1) showing that bank savings accounts
offer a guaranteed return of principal and a fixed rate of interest, but no
opportunity for capital growth; and (2)  describing Wells Fargo Bank, and its
affiliates and predecessors, as one of the first investment managers to advise
investment accounts using asset allocation and index strategies.  The Company
also may include in advertising and other types of literature information and
other data from reports and studies prepared by the Tax Foundation, including
information regarding federal and state tax levels and the related "Tax Freedom
Day."

   The Company also may discuss in advertising and other types of literature
that a Fund has been assigned a rating by a nationally recognized statistical
rating organization ("NRSRO"), such as Standard & Poor's Corporation.  Such
rating would assess the creditworthiness of the investments held by the Fund.
The assigned rating would not be a recommendation to purchase, sell or hold the
Fund's shares since the rating would not comment on the market price of the
Fund's shares or the suitability of the Fund for a particular investor.  In
addition, the assigned rating would be subject to change, suspension or
withdrawal as a result of changes in, or unavailability of, information relating
to the Fund or its investments.  The Company may compare the Fund's performance
with other investments which are assigned ratings by NRSROs.  Any such
comparisons may be useful to investors who wish to compare the Fund's past
performance with other rated investments.

   From time to time, the Funds may use the following statements, or variations
thereof, in advertisements and other promotional materials:  "Wells Fargo Bank,
as a Shareholder Servicing Agent for the Stagecoach Funds, provides various
services to its customers that are also 

                                      24
<PAGE>
 
shareholders of the Funds. These services may include access to Stagecoach
Funds' account information through Automated Teller Machines (ATMs), the
placement of purchase and redemption requests for shares of the Funds through
ATMs and the availability of combined Wells Fargo Bank and Stagecoach Funds
account statements."

   The Company also may disclose, in advertising and other types of literature,
information and statements that Wells Fargo Investment Management ("WFIM"), a
division of Wells Fargo Bank, is listed in the top 100 by Institutional Investor
magazine in its July 1996 survey "America's Top 300 Money Managers."  This
survey ranks money managers in several asset categories.  The Company may also
disclose in advertising and other types of sales literature the assets and
categories of assets under management by the Company's investment adviser.  The
Company may also disclose in advertising and other types of sales literature the
assets and categories of assets under management by a fund's investment adviser
or sub-adviser and the total amount of assets and mutual fund assets managed by
Wells Fargo Bank.  As of August 1, 1997, Wells Fargo Bank and its affiliates
provided investment Advisory services for approximately $57 billion of assets of
individual, trusts, estates and institutions and $19 billion of mutual fund
assets.

   The Company also may discuss in advertising and other types of literature the
features, terms and conditions of Wells Fargo Bank accounts through which
investments in the Funds may be made via a "sweep" arrangement, including,
without limitation, the Managed Sweep Account, Money Market Checking Account,
California Tax-Free Money Market Checking Account, Money Market Access Account
and California Tax-Free Money Market Access Account (collectively, the "Sweep
Accounts").  Such advertisements and other literature may include, without
limitation, discussions of such terms and conditions as the minimum deposit
required to open a Sweep Account, a description of the yield earned on shares of
the Funds through a Sweep Account, a description of any monthly or other service
charge on a Sweep Account and any minimum required balance to waive such service
charges, any overdraft protection plan offered in connection with a Sweep
Account, a description of any ATM or check privileges offered in connection with
a Sweep Account and any other terms, conditions, features or plans offered in
connection with a Sweep Account.  Such advertising or other literature may also
include a discussion of the advantages of establishing and maintaining a Sweep
Account, and may include statements from customers as to the reasons why such
customers have established and maintained a Sweep Account.

   The Company may disclose in advertising and other types of literature that
investors can open and maintain Sweep Accounts over the Internet or through
other electronic channels (collectively, "Electronic Channels").  Such
advertising and other literature may discuss the investment options available to
investors, including the types of accounts and any applicable fees.  Such
advertising and other literature may disclose that Wells Fargo Bank is the first
major bank to offer an on-line application for a mutual fund account that can be
filled out completely through Electronic Channels.  Advertising and other
literature may disclose that Wells Fargo Bank may maintain Web sites, pages or
other information sites accessible through Electronic Channels (an "Information
Site") and may describe the contents and features of the Information Site and
instruct investors on how to access the Information Site and open a Sweep
Account.  

                                      25
<PAGE>
 
Advertising and other literature may also disclose the procedures employed by
Wells Fargo Bank to secure information provided by investors, including
disclosure and discussion of the tools and services for accessing Electronic
Channels. Such advertising or other literature may include discussions of the
advantages of establishing and maintaining a Sweep Account through Electronic
Channels and testimonials from Wells Fargo Bank customers or employees and may
also include descriptions of locations where product demonstrations may occur.
The Company may also disclose the ranking of Wells Fargo Bank as one of the
largest money managers in the United States.

                        DETERMINATION OF NET ASSET VALUE


   Net asset value per share for the Service Class shares of the Prime Money
Market Mutual and Treasury Money Market Mutual Funds is determined as of 12:00
noon and 1:00 p.m. (Pacific time) on each day the NYSE is open for business.
Expenses and fees, including advisory fees, are accrued daily and are taken into
account for the purpose of determining the net asset value of the Funds' shares.

   Each Fund uses the amortized cost method to determine the value of its
portfolio securities pursuant to Rule 2a-7 under the 1940 Act.  The amortized
cost method involves valuing a security at its cost and amortizing any discount
or premium over the period until maturity, regardless of the impact of
fluctuating interest rates on the market value of the security.  While this
method provides certainty in valuation, it may result in periods during which
the value, as determined by amortized cost, is higher or lower than the price
that the Funds would receive if the security were sold.  During these periods
the yield to a shareholder may differ somewhat from that which could be obtained
from a similar fund that uses a method of valuation based upon market prices.
Thus, during periods of declining interest rates, if the use of the amortized
cost method resulted in a lower value of the Funds' portfolio on a particular
day, a prospective investor in the Funds would be able to obtain a somewhat
higher yield than would result from investment in a fund using solely market
values, and existing Fund shareholders would receive correspondingly less
income.  The converse would apply during periods of rising interest rates.

   Rule 2a-7 provides that in order to value its portfolio using the amortized
cost method, a Fund must maintain a dollar-weighted average portfolio maturity
of 90 days or less, purchase securities having remaining maturities (as defined
in Rule 2a-7) of thirteen months or less and invest only in those high-quality
securities that are determined by the Board of Directors to present minimal
credit risks.  The maturity of an instrument is generally deemed to be the
period remaining until the date when the principal amount thereof is due or the
date on which the instrument is to be redeemed.  However, Rule 2a-7 provides
that the maturity of an instrument may be deemed shorter in the case of certain
instruments, including certain variable and floating rate instruments subject to
demand features.  Pursuant to the Rule, the Board is required to establish
procedures designed to stabilize, to the extent reasonably possible, a Fund's
price per share as computed for the purpose of sales and redemptions at $1.00.
Such procedures include review of the Fund's portfolio holdings by the Board of
Directors, at such intervals as it may 

                                      26
<PAGE>
 
deem appropriate, to determine whether the Fund's net asset value calculated by
using available market quotations deviates from $1.00 per share based on
amortized cost. The extent of any deviation will be examined by the Board of
Directors. If such deviation exceeds 1/2 of 1%, the Board will promptly consider
what action, if any, will be initiated. In the event the Board determines that a
deviation exists that may result in material dilution or other unfair results to
investors or existing shareholders, the Board will take such corrective action
as it regards as necessary and appropriate, including the sale of portfolio
instruments prior to maturity to realize capital gains or losses or to shorten
average portfolio maturity, withholding dividends or establishing a net asset
value per share by using available market quotations. It is the intention of the
Funds to maintain a per share net asset value of $1.00, but there can be no
assurance that each Fund will do so.

   Instruments having variable or floating interest rates or demand features may
be deemed to have remaining maturities as follows: (a) a government security
with a variable rate of interest readjusted no less frequently than every
thirteen months may be deemed to have a maturity equal to the period remaining
until the next readjustment of the interest rate; (b) an instrument with a
variable rate of interest, the principal amount of which is scheduled on the
face of the instrument to be paid in thirteen months or less, may be deemed to
have a maturity equal to the period remaining until the next readjustment of the
interest rate; (c) an instrument with a variable rate of interest that is
subject to a demand feature may be deemed to have a maturity equal to the longer
of the period remaining until the next readjustment of the interest rate or the
period remaining until the principal amount can be recovered through demand; (d)
an instrument with a floating rate of interest that is subject to a demand
feature may be deemed to have a maturity equal to the period remaining until the
principal amount can be recovered through demand; and (e) a repurchase agreement
may be deemed to have a maturity equal to the period remaining until the date on
which the repurchase of the underlying securities is scheduled to occur or,
where no date is specified but the agreement is subject to demand, the notice
period applicable to a demand for the repurchase of the securities.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

   Shares may be purchased on any day a Fund is open for business (a "Business
Day").  The Funds are open Monday through Friday and are closed on federal bank
holidays.  Currently, those holidays are New Year's Day, President's Day, Martin
Luther King Jr. Day, Memorial Day, Independence Day, Labor Day, Columbus Day,
Veterans Day, Thanksgiving Day and Christmas Day.

   Payment for shares may, in the discretion of the adviser, be made in the form
of securities that are permissible investments for the Funds.  For further
information about this form of payment please contact Stephens.  In connection
with an in-kind securities payment, the Funds will require, among other things,
that the securities be valued on the day of purchase in accordance with the
pricing methods used by a Fund and that such Fund receives satisfactory
assurances that (i) it will have good and marketable title to the securities
received by it; (ii) that the securities are in proper form for transfer to the
Fund; and (iii) adequate information will be provided concerning the basis and
other matters relating to the securities.

                                      27
<PAGE>
 
   Under the 1940 Act, the Funds may suspend the right of redemption or postpone
the date of payment upon redemption for any period during which the NYSE is
closed (other than customary weekend and holiday closings, or during which
trading is restricted, or during which as determined by the SEC by rule or
regulation) an emergency exists as a result of which disposal or valuation of
portfolio securities is not reasonably practicable, or for such periods as the
SEC may permit.  The Company may also redeem shares involuntarily or make
payment for redemption in securities or other property if it appears appropriate
to do so in light of the Company's responsibilities under the 1940 Act.  In
addition, the Company may redeem shares involuntarily to reimburse the Funds for
any losses sustained by reason of the failure of a shareholders to make full
payment for shares purchased or to collect any charge relating to a transaction
effected for the benefit of a shareholder which is applicable to shares of a
Fund.

                             PORTFOLIO TRANSACTIONS

   The Company has no obligation to deal with any dealer or group of dealers in
the execution of transactions in portfolio securities.  Subject to policies
established by the Company's Board of Directors, Wells Fargo Bank is responsible
for each Fund's portfolio decisions and the placing of portfolio transactions.
In placing orders, it is the policy of the Company to obtain the best results
taking into account the dealer's general execution and operational facilities,
the type of transaction involved and other factors such as the dealer's risk in
positioning the securities involved.  While Wells Fargo Bank generally seeks
reasonably competitive spreads or commissions, the Funds will not necessarily be
paying the lowest spread or commission available.

   Purchases and sales of non-equity securities usually will be principal
transactions.  Portfolio securities normally will be purchased or sold from or
to dealers serving as market makers for the securities at a net price.  Each of
the Funds also will purchase portfolio securities in underwritten offerings and
may purchase securities directly from the issuer.  Generally, municipal
obligations and taxable money market securities are traded on a net basis and do
not involve brokerage commissions.  The cost of executing a Fund's portfolio
securities transactions will consist primarily of dealer spreads and
underwriting commissions.  Under the Act, persons affiliated with the Company
are prohibited from dealing with the Company as a principal in the purchase and
sale of securities unless an exemptive order allowing such transactions is
obtained from the Commission or an exemption is otherwise available.  The Fund
may purchase securities from underwriting syndicates of which Stephens or Wells
Fargo Bank is a member under certain conditions in accordance with the
provisions of a rule adopted under the Act and in compliance with procedures
adopted by the Board of Directors.

   Wells Fargo Bank, as the Investment Adviser of each of the Funds, may, in
circumstances in which two or more dealers are in a position to offer comparable
results for a Fund portfolio transaction, give preference to a dealer that has
provided statistical or other research services to Wells Fargo Bank.  By
allocating transactions in this manner, Wells Fargo Bank is able to supplement
its research and analysis with the views and information of securities firms.
Information so received will be in addition to, and not in lieu of, the services
required to be 

                                      28
<PAGE>
 
performed by Wells Fargo Bank under the Advisory Contracts, and the expenses of
Wells Fargo Bank will not necessarily be reduced as a result of the receipt of
this supplemental research information. Furthermore, research services furnished
by dealers through which Wells Fargo Bank places securities transactions for a
Fund may be used by Wells Fargo Bank in servicing its other accounts, and not
all of these services may be used by Wells Fargo Bank in connection with
advising the Funds.

   Brokerage Commissions.  The Funds did not pay any brokerage commissions on
   ---------------------                                                     
portfolio transactions for the nine-month period ended September 30, 1996 and
the six-month period ended March 31, 1997.

   Securities of Regular Broker/Dealers.  As of March 31, 1997, the Funds owned
   ------------------------------------                                        
securities of their "regular brokers or dealers" or their parents, as defined in
the Act as follows:

   Portfolio Turnover.  The portfolio turnover rate is not a limiting factor
   ------------------                                                       
when Wells Fargo Bank deems portfolio changes appropriate.  Changes may be made
in the portfolios consistent with the investment objectives and policies of the
Funds whenever such changes are believed to be in the best interests of the
Funds and their shareholders.  The portfolio turnover rate is calculated by
dividing the lesser of purchases or sales of portfolio securities by the average
monthly value of the Fund's portfolio securities.  For purposes of this
calculation, portfolio securities exclude all securities having a maturity when
purchased of one year or less.  Portfolio turnover generally involves some
expenses to the Funds, including brokerage commissions or dealer mark-ups and
other transaction costs on the sale of securities and the reinvestment in other
securities.  Portfolio turnover also can generate short-term capital gain tax
consequences.  Portfolio turnover rate is not a limiting factor when Wells Fargo
Bank deems portfolio changes appropriate.

                                 FUND EXPENSES

   From time to time, Wells Fargo Bank and Stephens may waive fees from the
Funds in whole or in part.  Any such waiver will reduce expenses and,
accordingly, have a favorable impact on a Fund's performance.  Except for the
expenses borne by Wells Fargo Bank and Stephens, the Company bears all costs of
its operations, including the compensation of its Directors who are not
affiliated with Stephens or Wells Fargo Bank or any of their affiliates;
advisory, shareholder servicing and administration fees; payments pursuant to
any Plan; interest 

                                      29
<PAGE>
 
charges; taxes; fees and expenses of its independent accountants, legal counsel,
transfer agent and dividend disbursing agent; expenses of redeeming shares;
expenses of preparing and printing prospectuses (except the expense of printing
and mailing prospectuses used for promotional purposes, unless otherwise payable
pursuant to a Plan), shareholders' reports, notices, proxy statements and
reports to regulatory agencies; insurance premiums and certain expenses relating
to insurance coverage; trade association membership dues; brokerage and other
expenses connected with the execution of portfolio transactions; fees and
expenses of its custodian, including those for keeping books and accounts and
calculating the NAV per share of a Fund; expenses of shareholders' meetings;
expenses relating to the issuance, registration and qualification of a Fund's
shares; pricing services, and any extraordinary expenses. Expenses attributable
to a Fund are charged against a Fund assets. General expenses of the Company are
allocated among all of the funds of the Company, including a Fund, in a manner
proportionate to the net assets of each Fund, on a transactional basis, or on
such other basis as the Company's Board of Directors deems equitable.

                              FEDERAL INCOME TAXES

   The following information supplements and should be read in conjunction with
the Prospectus section entitled "Taxes."  The Prospectus describes generally the
tax treatment of distributions by the Funds.  This section of the SAI includes
additional information concerning income taxes.

   General.  The Company intends to qualify each Fund as a regulated investment
   -------                                                                     
company under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code"), as long as such qualification is in the best interest of the Fund's
shareholders.  Each Fund will be treated as a separate entity for tax purposes
and thus the provisions of the Code applicable to regulated investment companies
will generally be applied to each Fund, rather than to the Company as a whole.
In addition, net capital gain, net investment income, and operating expenses
will be determined separately for each Fund. As a regulated investment company,
each Fund will not be taxed on its net investment income and capital gains
distributed to its shareholders.

   Qualification as a regulated investment company under the Code requires,
among other things, that (a) each Fund derive at least 90% of its annual gross
income from dividends, interest, certain payments with respect to securities
loans, gains from the sale or other disposition of stock or securities or
foreign currencies (to the extent such currency gains are directly related to
the regulated investment company's principal business of investing in stock or
securities) and other income (including but not limited to gains from options,
futures or forward contracts) derived with respect to its business of investing
in such stock, securities or currencies; and (b) the Fund diversify its holdings
so that, at the end of each quarter of the taxable year, (i) at least 50% of the
market value of the Fund's assets is represented by cash, government securities
and other securities limited in respect of any one issuer to an amount not
greater than 5% of the Fund's 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
obligations and the securities of other regulated investment companies), or in
two or more issuers 

                                      30
<PAGE>
 
which the Fund controls and which are determined to be engaged in the same or
similar trades or businesses.

   The Funds must also distribute or be deemed to distribute to their
shareholders at least 90% of their net investment income earned in each taxable
year.  In general, these distributions must actually or be deemed to be made in
the taxable year.  However, in certain circumstances, such distributions may be
made in the 12 months following the taxable year.  The Funds intend to pay out
substantially all of their net investment income and net realized capital gains
(if any) for each year.

   In addition, a regulated investment company must, in general, derive less
than 30% of its gross income from the sale or other disposition of securities or
options thereon held for less than three months.  However, this restriction has
been repealed with respect to a regulated investment company's taxable years
beginning after August 5, 1997.

   Excise Tax.  A 4% nondeductible excise tax will be imposed on each Fund
   ----------                                                             
(other than to the extent of its tax-exempt interest income) to the extent it
does not meet certain minimum distribution requirements by the end of each
calendar year.  Each Fund intends to actually or be deemed to distribute
substantially all of its net investment income and net capital gains by the end
of each calendar year and, thus, expects not to be subject to the excise tax.

   Taxation of Fund Investments.  Except as provided herein, gains and losses on
   ----------------------------                                                 
the sale of portfolio securities by a Fund will generally be capital gains and
losses.  Such gains and losses will ordinarily be long-term capital gains and
losses if the securities have been held by the Fund for more than one year at
the time of disposition of the securities.

   Gains recognized on the disposition of a debt obligation (including tax-
exempt obligations purchased after April 30, 1993) purchased by the Fund at a
market discount (generally at a price less than its principal amount) will be
treated as ordinary income to the extent of the portion of market discount which
accrued, but was not previously recognized pursuant to an available election,
during the term the Fund held the debt obligation.

   Capital Gain Distributions.  Distributions which are designated by a Fund as
   --------------------------                                                  
capital gain distributions will be taxed to shareholders as long-term capital
gain (to the extent such dividends do exceed the Fund's actual net capital gain
for the taxable year), regardless of how long a shareholder has held Fund
shares.  Such distributions will be designated as capital gain distributions in
a written notice mailed by the Fund to its shareholders not later than 60 days
after the close of the Fund's taxable year.

   The Taxpayer Relief Act of 1997 (the "1997 Act") created several new
categories of capital gains applicable to noncorporate taxpayers.  Under prior
law, noncorporate taxpayers were generally taxed at a maximum rate of 28% on net
capital gain (generally, the excess of net long-term capital gain over net
short-term capital loss).  Noncorporate taxpayers are now generally taxed at a
maximum rate of 20% on net capital gain attributable to gains realized on the
sale of property held for greater than 18 months, and a maximum rate of 28% on
net capital gain attributable to gain realized on the sale of property held for
greater than one year and not more 

                                      31
<PAGE>
 
than 18 months. The 1997 Act retains the treatment of short term capital gain or
loss (generally, gain or loss attributable to capital assets held for 1 year or
less) and did not affect the taxation of capital gains in the hands of corporate
taxpayers.

   Under the 1997 Act, the Treasury is authorized to issue regulations for
application of the reduced capital gains tax rates to pass-through entities,
including regulated investment companies, such as the Funds.  Noncorporate
shareholders of the Funds may therefore qualify for the reduced rate of tax on
capital gain dividends paid by the Funds.

   Other Distributions.  Although dividends will be declared daily based on each
   -------------------                                                          
Fund's daily earnings, for federal income tax purposes, the Fund's earnings and
profits will be determined at the end of each taxable year and will be allocated
pro rata over the entire year.  For federal income tax purposes, only amounts
paid out of earnings and profits will qualify as dividends.  Thus, if during a
taxable year a Fund's declared dividends (as declared daily throughout the year)
exceed the Fund's net income (as determined at the end of the year), only that
portion of the year's distributions which equals the year's earnings and profits
will be deemed to have constituted a dividend.  It is expected that each Fund's
net income, on an annual basis, will equal the dividends declared during the
year.

   Disposition of Fund Shares.  A disposition of Fund shares pursuant to
   --------------------------                                           
redemption (including a redemption in-kind) or exchanges will ordinarily result
in a taxable capital gain or loss, depending on the amount received for the
shares (or are deemed to receive in the case of an exchange) and the cost of the
shares.

   If a shareholder exchanges or otherwise disposes of Fund shares within 90
days of having acquired such shares and if, as a result of having acquired those
shares, the shareholder subsequently pays a reduced sales charge on a new
purchase of shares of the Fund or a different regulated investment company, the
sales charge previously incurred acquiring the Fund's shares shall not be taken
into account (to the extent such previous sales charges do not exceed the
reduction in sales charges on the new purchase) for the purpose of determining
the amount of gain or loss on the disposition, but will be treated as having
been incurred in the acquisition of such other shares.  Also, any loss realized
on a redemption or exchange of shares of the Fund will be disallowed to the
extent that substantially identical shares are acquired within the 61-day period
beginning 30 days before and ending 30 days after the shares are disposed of.

   If a shareholder receives a designated capital gain distribution (to be
treated by the shareholder as long-term capital gain) with respect to any Fund
share and such Fund share is held for six months or less, then (unless otherwise
disallowed) any loss on the sale or exchange of that Fund share will be treated
as long-term capital loss to the extent of the designated capital gain
distribution. In addition, if a shareholder holds Fund shares for six months or
less, any loss on the sale or exchange of those shares will be disallowed to the
extent of the amount of exempt-interest dividends received with respect to the
shares.  The Treasury Department is authorized to issue regulations reducing the
six months holding requirement to a period of not less than the greater of 31
days or the period between regular dividend distributions where a Fund regularly
distributes at least 90% of its net tax-exempt interest, if any.  No such
regulations had been 

                                      32
<PAGE>
 
issued as of the date of this SAI. The loss disallowance rules described in this
paragraph do not apply to losses realized under a periodic redemption plan.

   Federal Income Tax Rates.  As of the printing of this SAI, the maximum
   ------------------------                                              
individual tax rate applicable to ordinary income is 39.6% (marginal tax rates
may be higher for some individuals to reduce or eliminate the benefit of
exemptions and deductions); the maximum individual marginal tax rate applicable
to net capital gain is 28% (however, see "Capital Gain Distributions" above);
and the maximum corporate tax rate applicable to ordinary income and net capital
gain is 35% (marginal tax rates may be higher for some corporations to reduce or
eliminate the benefit of lower marginal income tax rates).  Naturally, the
amount of tax payable by an individual or corporation will be affected by a
combination of tax laws covering, for example, deductions, credits, deferrals,
exemptions, sources of income and other matters.

   Backup Withholding.  The Company may be required to withhold, subject to
   ------------------                                                      
certain exemptions, at a rate of 31% ("backup withholding") on dividends,
capital gain distributions, and redemption proceeds (including proceeds from
exchanges and redemptions in-kind) paid or credited to an individual Fund
shareholder, unless the shareholder certifies that the Taxpayer Identification
Number ("TIN") provided is correct and that the shareholder is not subject to
backup withholding, or the IRS notifies the Company that the shareholder's TIN
is incorrect or that the shareholder is subject to backup withholding.  Such tax
withheld does not constitute any additional tax imposed on the shareholder, and
may be claimed as a credit or refund on the shareholder's federal income tax
return.  An investor must provide a valid TIN upon opening or reopening an
account.  Failure to furnish a valid TIN to the Company could subject the
investor to penalties imposed by the IRS.  Foreign shareholders of the Funds
(described below) are generally not subject to backup withholding.

   Foreign Shareholders.  Under the Code, distributions of net investment income
   --------------------                                                         
by a Fund to a nonresident alien individual, foreign trust (i.e., trust which a
U.S. court is able to exercise primary supervision over administration of that
trust and one or more U.S. persons have authority to control substantial
decisions of that trust), foreign estate (i.e., the income of which is not
subject to U.S. tax regardless of source), foreign corporation, or foreign
partnership (a "foreign shareholder") will be subject to U.S. income tax
withholding (at a rate of 30% or a lower treaty rate, if applicable).
Withholding will not apply if a dividend distribution paid by a Fund to a
foreign shareholder is "effectively connected" with a U.S. trade or business
(or, if an income tax treaty applies, is attributable to a U.S. permanent
establishment of the foreign shareholder), in which case the reporting and
withholding requirements applicable to U.S. residents will apply.  Distributions
of net capital gain are generally not subject to U.S. income tax withholding.

   New Regulations.  On October 6, 1997, the Treasury Department issued new
   ---------------                                                         
regulations (the "New Regulations") which make certain modifications to the
backup withholding, U.S. income tax withholding and information reporting rules
applicable to foreign shareholders.  The New Regulations will generally be
effective for payments made after December 31, 1998, subject to certain
transition rules.  Among other things, the New Regulations will permit the Funds
to estimate the portion of their distributions qualifying as capital gain
distributions for purposes of 

                                      33
<PAGE>
 
determining the portion of such distributions paid to foreign shareholders which
will be subject to U.S. income tax withholding. Prospective investors are urged
to consult their own tax advisors regarding the New Regulations.

   Tax-Deferred Plans.  The shares of the Funds are available for a variety of
   ------------------                                                         
tax-deferred retirement and other plans, including Individual Retirement
Accounts ("IRA"), Simplified Employee Pension Plans ("SEP-IRA"), Savings
Incentive Match Plans for Employees ("SIMPLE plans"), Roth IRAs, and Education
IRAs, which permit investors to defer some of their income from taxes.
Investors should contact their selling agents for details concerning retirement
plans.

   Other Matters.  Investors should be aware that the investments to be made by
   -------------                                                               
a Fund may involve sophisticated tax rules that may result in income or gain
recognition by the Fund without corresponding current cash receipts.  Although
the Funds will seek to avoid significant noncash income, such noncash income
could be recognized by a Fund, in which case the Fund may distribute cash
derived from other sources in order to meet the minimum distribution
requirements described above.

   The foregoing discussion and the discussions in the Prospectus applicable to
each shareholder address only some of the federal income tax considerations
generally affecting investments in a Fund.  Each investor is urged to consult
his or her tax advisor regarding specific questions as to federal, state, local
and foreign taxes.

                                 CAPITAL STOCK

   The Funds are two of the funds in the Stagecoach Family of Funds. The Company
was organized as a Maryland corporation on September 9, 1991, and currently
offers shares of over thirty funds.

   Most of  the Company's funds are authorized to issue multiple classes of
shares, one class generally subject to a front-end sales charge and, in some
cases, classes subject to a contingent-deferred sales charge, that are offered
to retail investors.  Certain of the Company's funds also are authorized to
issue other classes of shares, which are sold primarily to institutional
investors.  Each class of shares in a fund represents an equal, proportionate
interest in a fund with other shares of the same class.  Shareholders of each
class bear their pro rata portion of the fund's operating expenses, except for
certain class-specific expenses (e.g., any state securities registration fees,
shareholder servicing fees or distribution fees that may be paid under Rule 12b-
1) that are allocated to a particular class.  Please contact Stagecoach
Shareholder Services at 1-800-222-8222 if you would like additional information
about other funds or classes of shares offered.

   With respect to matters that affect one class but not another, shareholders
vote as a class; for example, the approval of a Plan.  Subject to the foregoing,
all shares of a Fund have equal voting rights and will be voted in the
aggregate, and not by series, except where voting by a series is required by law
or where the matter involved only affects one series.  For example, a change in
a Fund's fundamental investment policy affects only one Series and would be
voted upon only by shareholders of the Fund involved.  Additionally, approval of
an advisory contract since it affects 

                                      34
<PAGE>
 
only one Fund, is a matter to be determined separately by each Series. Approval
by the shareholders of one Series is effective as to that Series whether or not
sufficient votes are received from the shareholders of the other Series to
approve the proposal as to those Series.

   As used in the Prospectus and in this SAI, the term "majority" when referring
to approvals to be obtained from shareholders of a Class of a Fund, means the
vote of the lesser of (i) 67% of the shares of such class of the Fund
represented at a meeting if the holders of more than 50% of the outstanding
shares of such Class Fund are present in person or by proxy, or (ii) more than
50% of the outstanding shares of such Class of the Fund.  The term "majority,"
when referring to the approvals to be obtained from shareholders of the Company
as a whole, means the vote of the lesser of (i) 67% of the Company's shares
represented at a meeting if the holders of more than 50% of the Company's
outstanding shares are present in person or by proxy, or (ii) more than 50% of
the Company's outstanding shares.

   Shareholders are entitled to one vote for each full share held and fractional
votes for fractional shares held.  Shareholders are not entitled to any
preemptive rights.  All shares, when issued, will be fully paid and non-
assessable by the Company.

   The Company may dispense with an annual meeting of shareholders in any year
in which it is not required to elect directors under the 1940 Act.

   Each share of a class of a Fund represents an equal proportional interest in
the Fund with each other share in the same class and is entitled to such
dividends and distributions out of the income earned on the assets belonging to
the Fund as are declared in the discretion of the Directors.  In the event of
the liquidation or dissolution of the Company, shareholders of a Fund or class
are entitled to receive the assets attributable to the Fund or class that are
available for distribution, and a distribution of any general assets not
attributable to a particular investment portfolio that are available for
distribution in such manner and on such basis as the Directors in their sole
discretion may determine.

   Set forth below as of October 31, 1997 is the name, address and share
ownership of each person known by the Company to have beneficial or record
ownership of 5% or more of a class of each Fund or 5% or more of the voting
securities of each Fund as a whole.

                                  SAI APPENDIX

     The following is a description of the ratings given by Moody's and S&P to
corporate and municipal bonds, municipal notes, and corporate and municipal
commercial paper. 


Corporate and Municipal Bonds

     Moody's: The four highest ratings for corporate and municipal bonds are
"Aaa," "Aa," "A" and "Baa." Bonds rated "Aaa" are judged to be of the "best
quality" and carry the smallest amount of investment risk. Bonds rated "Aa" are
of "high quality by all standards," but margins of protection or other elements
make long-term risks appear somewhat greater than "Aaa" rated bonds. Bonds rated
"A" possess many favorable investment attributes and are considered to be upper
medium grade obligations. Bonds rated "Baa" are considered to be medium grade
obligations; interest payments and principal security appear adequate for the
present, but certain protective elements may be lacking or may be
characteristically unreliable over any great length of time. Such bonds have
speculative characteristics as well. Moody's applies numerical modifiers: 1, 2
and 3 in each rating category from "Aa" through "Baa" in its rating system. The
modifier 1 indicates that the security ranks in the higher end of its category;
the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that
the issue ranks in the lower end.

     S&P:  The four highest ratings for corporate and municipal bonds are
"AAA," "AA," "A" and "BBB."  Bonds rated "AAA" have the highest ratings assigned
by S&P and have an extremely strong capacity to pay interest and repay
principal.  Bonds rated "AA" have a "very strong capacity to pay interest and
repay principal" and differ "from the highest rated issued only in small
degree."  Bonds rated "A" have a "strong capacity" to pay interest and repay
principal, but are "somewhat more susceptible" to adverse effects of changes in
economic conditions or other circumstances than bonds in higher rated
categories.  Bonds rated "BBB" are regarded as having an "adequate capacity" to
pay interest and repay principal, but changes in economic conditions or other
circumstances are more likely to lead to a "weakened capacity" to make such
repayments.  The ratings from "AA" to "BBB" may be modified by the addition of a
plus or minus sign to show relative standing within the category.

Municipal Notes

     Moody's:  The highest ratings for state and municipal short-term
obligations are "MIG 1," "MIG 2," and "MIG 3" (or "VMIG 1," "VMIG 2" and "VMIG
3" in the case of an issue having a variable rate demand feature).  Notes rated
"MIG 1" or "VMIG 1" are judged to be of the "best quality."  Notes rated "MIG 2"
or "VMIG 2" are of "high quality," with margins of protections "ample although
not as large as in the preceding group."  Notes rated "MIG 3" or "VMIG 3" are of
"favorable quality," with all security elements accounted for, but lacking the
strength of the preceding grades.

     S&P:  The "SP-1" rating reflects a "very strong or strong capacity to
pay principal and interest."  Notes issued with "overwhelming safety
characteristics" will be rated "SP-1+."  The "SP-2" rating reflects a
"satisfactory capacity" to pay principal and interest.

                                      A-1
<PAGE>
 
Corporate and Municipal Commercial Paper

     Moody's: The highest rating for corporate and municipal commercial paper is
"P-1" (Prime-1). Issuers rated "P-1" have a "superior capacity for repayment of
short-term promissory obligations." Issuers rated "P-2" (Prime-2) "have a strong
capacity for repayment of short-term promissory obligations," but earnings
trends, while sound, will be subject to more variation.

     S&P:  The "A-1" rating for corporate and municipal commercial paper
indicates that the "degree of safety regarding timely payment is either
overwhelming or very strong."  Commercial paper with "overwhelming safety
characteristics" will be rated "A-1+."  Commercial paper with a strong capacity
for timely payments on issues will be rated "A-2."

Item 27.  Indemnification
          ---------------

          The following paragraphs of Article VIII of the Registrant's Articles
of Incorporation provide:

          (h)  The Corporation shall indemnify (1) its Directors and Officers,
   whether serving the Corporation or at its request any other entity, to the
   full extent required or permitted by the General Laws of the State of
   Maryland now or hereafter in force, including the advance of expenses under
   the procedures and to the full extent permitted by law, and (2) its other
   employees and agents to such extent as shall be authorized by the Board of
   Directors or the Corporation's By-Laws and be permitted by law.  The
   foregoing rights of indemnification shall not be exclusive of any other
   rights to which those seeking indemnification may be entitled.  The Board of
   Directors may take such action as is necessary to carry out these
   indemnification provisions and is expressly empowered to adopt, approve and
   amend from time to time such By-Laws, resolutions or contracts implementing
   such provisions or such further indemnification arrangements as may be
   permitted by law.  No amendment of these Articles of Incorporation of the
   Corporation shall limit or eliminate the right to indemnification provided
   hereunder with respect to acts or omissions occurring prior to such amendment
   or repeal.  Nothing contained herein shall be construed to authorize the
   Corporation to indemnify any Director or officer of the Corporation against
   any liability to the Corporation or to any holders of securities of the
   Corporation to which he is subject by reason of willful misfeasance, bad
   faith, gross negligence, or reckless disregard of the duties involved in the
   conduct of his office.  Any indemnification by the Corporation shall be
   consistent with the requirements of law, including the 1940 Act.

          (i)  To the fullest extent permitted by Maryland statutory and
   decisional law and the 1940 Act, as amended or interpreted, no Director or
   officer of the Corporation shall be personally liable to the Corporation or
   its stockholders for money damages; provided, however, that nothing herein
   shall be construed to protect any Director or officer of the Corporation
   against any liability to which such Director or officer would otherwise be
   subject by reason of willful misfeasance, bad faith, gross negligence, or
   reckless disregard of the duties involved in the conduct of his office. No
   amendment, modification or repeal of this Article VIII shall adversely affect
   any right or protection of a Director or officer that exists at the time of
   such amendment, modification or repeal.

                 indemnification against such liabilities (other than the
                 payment by the registrant of expenses incurred or paid by a
                 director, officer or controlling person of the registrant in

                 asserted by such director, officer or controlling person in
                 connection with the securities being registered, the registrant
                 will, unless in the opinion of its counsel the matter has been
                 settled by controlling precedent, submit to a court of
                 appropriate jurisdiction the question whether such
                 indemnification by it is against public policy as expressed in
                 the Act and will be governed by the final adjudication of such
                 issue

          SIXTH:  A description of the preferences, conversion and other rights,
voting powers, restrictions, limitations as to dividends, qualifications and
terms and conditions of redemption of the class of shares classified and
designated as Class B shares of the Equity Index Series in Article SECOND ( the
"Class B shares") hereto are as follows:

          1.    Assets Belonging to a Class.  All consideration received by
                ---------------------------                                
      the Corporation for the issue or sale of the Class B shares shall be
      invested and reinvested with the consideration received by the Corporation
      for the issue and sale of all other shares now or hereafter designated as
      a class of the Equity Index  Series together with all assets in which such
      consideration is invested and reinvested, income, earnings, profits and
      proceeds thereof, including any proceeds derived from the sale, exchange
      or liquidation thereof, and any funds or payments derived from any
      reinvestment of such proceeds in whatever form the same may be, and any
      general assets of the Corporation allocated to the Class B shares or such
      other shares by the Board of Directors in accordance with the
      Corporation's Charter, shall irrevocably belong to the Class B shares or
      such other shares with respect to which such assets, payments or funds
      were received by the Corporation for all purposes, subject only to the
      rights of creditors, and shall be so handled upon the books of account of
      the Corporation.  Such consideration, assets, income, earnings, profits
      and proceeds thereof, including any proceeds derived from the sale,
      exchange or liquidation thereof, and any assets derived from any
      reinvestment of such proceeds in whatever form, are herein referred to as
      "assets belonging to" the Class B shares.  Any assets, income, earnings,
      profits, and proceeds thereof, funds or payments which are not readily
      attributable to any particular class shall be allocable to the Class B
      shares or other series or class of the Corporation in such manner and on
      such basis as the Board of Directors, in its sole discretion, shall deem
      fair and equitable.
<PAGE>
 
          2.  Liabilities Belonging to a Class. The assets belonging to the
              --------------------------------
      Class B shares or any other share now or hereafter designated as a
      class of the Equity Index Series, shall be charged with the
      liabilities in respect of such Class, shall also be charged with such
      Class's share of the general liabilities of the Equity Index Series,
      and shall further be charged with such Class's share of the general
      liabilities of the Corporation charged to the Equity Index Series and
      determined as hereinafter provided. The determination of the Board of
      Directors shall be conclusive as to the amount of such liabilities,
      including the amount of accrued expenses and reserves, as to any
      allocation of such liabilities to the Equity Index Series or a given
      Class; and as to whether the same are allocable to one or more
      Classes of the Equity Index Series. The liabilities so allocated to a
      Class or the Equity Index Series are herein referred to as
      "liabilities belonging to" such Class or the Equity Index Series. Any
      liabilities which are not readily attributable to any particular
      Class shall be allocable among any one or more of the Classes in such
      manner and on such basis as the Board of Directors, in its sole
      discretion, shall deem fair and equitable.

          SEVENTH:  The total number of shares the Corporation is authorized to
issue remains at one hundred and six billion, seven hundred million
(106,700,000,000) shares and the aggregate par value of all shares having a par
value remains at one hundred and six million, seven hundred thousand dollars
($106,700,000).

          EIGHTH:  The Board of Directors has duly authorized the filing of
these Articles Supplementary.

          IN WITNESS WHEREOF, the Corporation has caused these presents to be
signed in its name and on its behalf by its President and witnessed by its
Assistant Secretary as of the 19th day of November, 1997.

          Re:  Shares of Common Stock of
               Stagecoach Funds, Inc.
               --------------------------

Ladies/Gentlemen:

        We refer to Post-Effective Amendment No. 36 and Amendment No. 37 to the 
Registration Statement on Form N-1A (SEC File Nos. 33-42927 and 811-6419) (the 
"Registration Statement") of Stagecoach Funds, Inc. (the "Company") relating to 
the registration of an indefinite number of shares of common stock of the 
following Funds: Arizona Tax-Free, Balanced, California Tax-Free Bond, 
California Tax-Free Income, Equity Value, Growth, Intermediate Bond, Money 
Market Mutual, National Tax-Free, National Tax-Free Money Market Mutual, Oregon 
Tax-Free, Overland Express Sweep, Prime Money Market Mutual, Short-Intermediate 
U.S. Government Income, Small Cap, Treasury Money Market Mutual, and U.S. 
Government Income (collectively, the "Shares").

        We have been requested by the Company to furnish this opinion as Exhibit
10 to the Registration Statement.

        We have examined documents relating to the organization of the Company 
and its series and the authorization and issuance of shares of its series.  We 
have also verified with the Company's transfer agent the maximum number of 
shares issued by the Company through November 1, 1997.

        Based upon and subject to the foregoing, we are of the opinion that:

        The issuance and sale of the Shares by the Company has been duly and 
validly authorized by all appropriate corporate action, and assuming delivery by
sale or in accord with the Company's dividend reinvestment plan in accordance 
with the description set forth in the Funds' current prospectuses under the 
Securities Act of 1933, as amended, the Shares will be legally issued, fully 
paid and nonassessable by the Company.

        We consent to the inclusion of this opinion as an exhibit to the 
Registration Statement.
