/1/Pursuant to the terms of the Investment Advisory Agreements between the
   Trust on behalf of each Series and the Advisor, the Advisor is entitled to
   receive a monthly fee at the following annual rates for each of the Global
   Fund, Global Equity Fund, Global Bond Fund, U.S. Balanced Fund, U.S. Equity
   Fund, U.S. Large Capitalization Equity Fund, U.S. Bond Fund and Non-U.S.
   Equity Fund: 0.80%, 0.80%, 0.75%, 0.70%, 0.70%, 0.70%, 0.50%, and 0.80%,
   respectively. The Advisor has irrevocably agreed to waive its fees and
   reimburse certain expenses so that the total operating expenses of the
   Global Fund, Global Equity Fund, Global Bond Fund, U.S. Balanced Fund, U.S.
   Equity Fund, U.S. Large Capitalization Equity Fund, U.S. Bond Fund and Non-
   U.S. Equity Fund will never exceed 1.10%, 1.00%, 0.90%, 0.80%, 0.80%, 0.80%,
   0.60% and 1.00%, respectively. Had the Advisor not irrevocably agreed to
   waive fees and reimburse expenses, the total fund operating expenses for the
   Brinson Fund Class I shares of the Series for the fiscal year ended June 30,
   1998 for the Global Equity Fund, Global Bond Fund, U.S. Balanced Fund, U.S.
   Large Capitalization Equity Fund, and U.S. Bond Fund would have been 1.02%,
   .96%, .81%, 1.59%, and .84%, respectively. The fees and expenses for the
   U.S. Large Capitalization Equity Fund are based on the period from April 6,
   1998 (commencement of operations) to June 30, 1998.     
 
EXAMPLE: Based on the level of expenses listed above after fee waiver or
expense reimbursement, the total expenses relating to an investment of $1,000
would be as follows, assuming a 5% annual return and redemption at the end of
each time period.

PRIOR PERFORMANCE OF ADVISOR
 
  The following table sets forth the Advisor's performance data relating to
the historical performance of funds contained within an institutional
collective investment trust ("CIT") (described below) managed by the Advisor.
Such CITs have investment objectives, policies, strategies and risks
substantially similar to those of the various Series of the Trust. The data is
provided to illustrate the past performance of the Advisor in managing
investment portfolios which are substantially similar to each applicable
Series of The Brinson Funds as measured against specified market indices. The
performance data of the Class I shares of each Series of the Trust is also
included in the table.
 
  The Advisor adopted the Performance Presentation Standards of the
Association for Investment Management and Research (AIMR Standards) as of
January 1, 1993. The CIT returns presented in this Prospectus are the
responsibility of the Advisor. They are presented in compliance with the
Performance Presentation Standards of the Association for Investment
Management and Research (AIMR--PPS(TM)). AIMR has not been involved with the
preparation or review of these returns.
 
  Investment results are time-weighted performance calculations representing
total return. Returns are calculated using geometric linking of monthly
returns. Each composite is a single entity composite, consisting of the assets
of each applicable fund of the Brinson Trust Company Collective Investment
Trust for Pension and Profit Sharing Trusts, or its predecessors, which may be
a single client. Clients must be an ERISA or governmental employee benefit
plan in order to qualify to invest in a CIT. Composites are valued monthly,
taking into account cash flows. All realized and unrealized capital gains and
losses, as well as all dividends and interest from investments and cash
balances, are included. Investment transactions are accounted for on a trade
date basis. Total returns for the CIT composites exclude the impact of
administrative expenses and the impact of any income taxes an investor might
have incurred as a result of taxable ordinary income and capital gains
realized by the CIT.
 
  The composite for each CIT is composed of all actual fee-paying,
discretionary client portfolios invested in the CIT. No alterations of
composites as presented here have occurred due to changes in personnel.
Accounts of all sizes invested in each CIT are included in composite
performance and no minimum account relationship size was set for inclusion in
the composites as the individual account size does not impact portfolio
management style. CITs are not subject to certain expenses, investment
limitations, diversification requirements and restrictions to which the Series
are subject and which are imposed by the Investment Company Act of 1940 (the
"Act") and the Internal Revenue Code of 1986, as amended. Had such expenses,
limitations, requirements and restrictions been applicable to the CITs, the
performance results of the CIT composites could have been adversely affected.
The CIT's performance presented does not represent the historical performance
of the Series and should not be interpreted as indicative of future
performance of the Series.

DESCRIPTION OF THE FUNDS
 
  The investment objective of each Series is fundamental and may not be
changed without the affirmative vote of the holders of a majority of the
outstanding voting securities of the Series, as defined in the Act. Unless
otherwise stated in this Prospectus or the Statement of Additional
Information, each Series' investment policies are not fundamental and may be
changed without shareholder approval. There can be no assurance that a Series
will achieve its investment objective.
 
  None of the Series intends to concentrate its investments in a particular
industry. None of the Series intends to issue senior securities as defined in
the Act, except that each Series may engage in borrowing activities as defined
in Appendix A and in the Statement of Additional Information. Each Series'
investment objective and its policies concerning portfolio lending, borrowing,
the issuance of senior securities and concentration are "fundamental," which
means that they may not be changed without the affirmative vote of the holders
of a majority of the Series' outstanding voting securities (as defined in the
Act).
 
INVESTMENT OBJECTIVES AND POLICIES
 
GLOBAL FUND
 
INVESTMENT OBJECTIVE
 
  The Global Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income. The Series will attempt
to control risk while seeking to achieve its investment objective. As a global
fund, at least 65% of the Series' total assets will be invested in securities
of issuers in at least three countries, one of which may be the United States.
The Series may utilize a wide range of equity, debt and money market
securities in domestic and foreign markets, and the Series may invest in other
open-end investment companies advised by Brinson Partners. The Series may
enter into repurchase agreements and reverse repurchase agreements, and engage
in futures, options and currency transactions for hedging and other
permissible purposes, as more fully described in "Investment Considerations
and Risks" and Appendix A in this Prospectus, and in the Statement of
Additional Information.
 
  The Series is a diversified portfolio that seeks to achieve its objective by
pursuing active asset allocation strategies across global equity and fixed
income markets and active security selection within each market. These
decisions are undertaken relative to the GSMI Mutual Fund Index (the "Global
Benchmark"), which is compiled by Brinson Partners. The Global Benchmark
consists of eight distinct asset classes representing the primary wealth-
holding public securities markets. These asset classes are U.S. equities, non-
U.S. equities, emerging markets equities, U.S. bonds, non-U.S. bonds, emerging
markets bonds, high yield bonds and cash equivalents. Each asset class is
represented in the Global Benchmark by an index compiled by an independent
data provider. In order to compile the Global Benchmark, the Advisor
determines current relative market capitalizations in the world markets (U.S.
equities, non-U.S. equities, emerging markets equities, U.S. bonds, non-U.S.
bonds, emerging markets bonds, high yield bonds and cash) and then weights
each relevant index. Based on this weighting, the Advisor determines the
return of the relative indices, applies the index weighting and then
 
                                       8
<PAGE>
 
determines the return of the Global Benchmark. From time to time, the Advisor
may substitute an equivalent index within a given asset class when it believes
that such index more accurately reflects the relevant global market.
 
  Although it may invest anywhere in the world, it is expected that the
Series' assets will be primarily invested in equity markets listed in the
Morgan Stanley Capital International ("MSCI") World Equity (Free) Index. The
Series will primarily invest in fixed income markets listed in the Salomon
World Government Bond Index. The Series may invest up to 10% of its net assets
in equity and debt securities of emerging market issuers, or securities with
respect to which the return is derived from the equity or debt securities of
issuers in emerging markets.
 
GLOBAL EQUITY FUND
 
INVESTMENT OBJECTIVE
 
  The Global Equity Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income. The Series will attempt
to control risk while seeking to achieve its investment objective. As a global
fund, at least 65% of the Series' total assets will be invested in equity
securities of issuers in at least three countries, one of which may be the
United States. The Series may utilize a wide range of equity securities that
are traded on both domestic and foreign stock exchanges or, in the case of
domestic stocks, in the over-the-counter market. The Series may enter into
repurchase agreements and reverse repurchase agreements, and engage in
futures, options and currency transactions for hedging and other permissible
purposes, as more fully described in "Investment Considerations and Risks" and
Appendix A in this Prospectus, and in the Statement of Additional Information.
 
  The Series is a diversified portfolio that seeks to achieve its objective by
pursuing an active asset allocation strategy across global equity markets,
active management of currency exposures and active security selection within
each market. The benchmark for the Series is the MSCI World Equity (Free)
Index (the "Global Equity Benchmark"). The Global Equity Benchmark is a market
driven broad based index which includes U.S. and non-U.S. equity markets in
terms of capitalization and performance. The Global Equity Benchmark is
designed to provide a representative total return for all major stock
exchanges located inside and outside the United States. Although it may invest
anywhere in the world, it is expected that the Series' assets will primarily
be invested in equity markets listed in the Global Equity Benchmark. From time
to time, the Advisor may substitute securities in an equivalent index when it
believes that such securities in the index more accurately reflect the
relevant global market.
 
GLOBAL BOND FUND
 
INVESTMENT OBJECTIVE
 
  The Global Bond Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income. The Series will attempt
to control risk while seeking to achieve its investment objective. As a global
fund, at least 65% of the Series' total assets will be invested in debt
securities with an initial maturity of more than one year of issuers in at
least three countries, one of which may be the United States. The Series seeks
to achieve this objective by investing primarily in debt securities that may
also provide the potential for capital appreciation. The Series may enter into
repurchase agreements and reverse repurchase agreements, and may engage in
futures, options and currency transactions for hedging and other permissible
purposes, as more fully described in "Investment Considerations and Risks" and
Appendix A in this Prospectus, and in the Statement of Additional Information.
 
  The Series is a non-diversified portfolio as described in "Investment
Considerations and Risks-Non-Diversified Status." The benchmark for the Series
is the Salomon World Government Bond Index (the "Global
 
                                       9
<PAGE>
 
Bond Benchmark"). The Global Bond Benchmark is a market driven index which
measures the broad global fixed income markets invested in debt issues of U.S.
and non-U.S. governments, governmental entities and supranationals. Although
it may invest anywhere in the world, it is expected that the Series' assets
will be
primarily invested in fixed income markets listed in the Global Bond
Benchmark. From time to time, the Advisor may substitute securities in an
equivalent index when it believes that such securities in the index more
accurately reflect the relevant global fixed income securities market.
 
U.S. BALANCED FUND
 
INVESTMENT OBJECTIVE
 
  The U.S. Balanced Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income. In seeking to achieve
its investment objective, the Series attempts to control risk. Under normal
circumstances, the Series will invest at least 25% of its net assets in fixed
income securities. The Series may utilize a wide range of equity, debt and
money market securities. The Series may also invest in equity securities,
including warrants, preferred stock and securities convertible into equity
securities. The Series may enter into repurchase agreements and reverse
repurchase agreements, and may engage in futures and options for hedging and
other permissible purposes, as more fully described in "Investment
Considerations and Risks" and Appendix A in this Prospectus, and in the
Statement of Additional Information. It is not the policy of the Series to
take unreasonable risks to obtain speculative or aggressively high returns.
 
  The Series is a diversified portfolio that seeks to achieve its objective by
pursuing active asset allocation strategies across U.S. equity and fixed
income markets and active security selection within each market. These
decisions are undertaken relative to the U.S. Balanced Mutual Fund Index (the
"U.S. Balanced Benchmark"), which is compiled by Brinson Partners. The U.S.
Balanced Benchmark represents a fixed composite of 65% Wilshire 5000 Index and
35% Salomon Brothers Broad Investment Grade (BIG) Bond Index. From time to
time, the Advisor may substitute an equivalent index within a given asset
class when the Advisor believes that such new index more accurately reflects
the relevant U.S. market.
 
U.S. EQUITY FUND
 
INVESTMENT OBJECTIVE
 
  The U.S. Equity Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income, while controlling risk.
Under normal circumstances, at least 65% of the Series' total assets will be
invested in equity securities of U.S. companies. The Series is a diversified
portfolio that seeks to achieve its objective by investing in a wide range of
equity securities of U.S. companies that are traded on major stock exchanges
as well as in the over-the-counter market. The Series may engage in futures
and options for hedging and other permissible purposes, as more fully
described in "Investment Considerations and Risks" and Appendix A in this
Prospectus, and in the Statement of Additional Information. The benchmark for
the Series is the Wilshire 5000 Index (the "U.S. Equity Benchmark"). The U.S.
Equity Benchmark is a broad weighted index which includes all U.S. common
stocks. The U.S. Equity Benchmark is designed to provide a representative
indication of the capitalization and return for the U.S. equity market.
 
U.S. LARGE CAPITALIZATION EQUITY FUND
 
INVESTMENT OBJECTIVE
 
  The U.S. Large Capitalization Equity Fund's investment objective is to
maximize total return, consisting of capital appreciation and current income,
while controlling risk. Under normal circumstances, at least 65% of the
Series' total assets will be invested in large capitalization equity
securities of U.S. companies. The Advisor defines large capitalization
companies as those with market capitalizations in the upper 65% of the
Wilshire 5000 Index
 
                                      10
<PAGE>
 
at the time of the Series' investment. Companies whose capitalization falls
below this level after purchase continue to be considered large capitalization
companies. The Series is a non-diversified portfolio as described in
"Investment Considerations and Risks-Non Diversified Status." The Series seeks
to achieve its objective by investing in a wide range of equity securities of
U.S. companies that are traded on major stock exchanges as well as in the
over-the-counter market. The Series may engage in futures and options for
hedging and other permissible purposes, as more fully described in "Investment
Considerations and Risk" and Appendix A in this Prospectus, and in the
Statement of Additional Information. The benchmark for the Series is the
Standard & Poor's 500 Stock Index (the "U.S. Large Capitalization Equity
Benchmark"). The U.S. Large Capitalization Equity Benchmark is a broad
weighted index which includes primarily U.S. common stock. The U.S. Large
Capitalization Equity Benchmark is designed to provide a representative
indication of the capitalization and return for the large capitalization U.S.
equity market.
 
U.S. BOND FUND
 
INVESTMENT OBJECTIVE
 
  The U.S. Bond Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income, while controlling risk.
As a matter of fundamental policy, under normal circumstances, the Series
intends to invest at least 65% of its total assets in U.S. debt securities
with an initial maturity of more than one year. The Series is a diversified
portfolio that seeks to achieve its objective by investing primarily in fixed
income securities, which may also provide the potential for capital
appreciation. The Series may also engage in futures and options transactions
for hedging and other permissible purposes, as more fully described in
"Investment Considerations and Risks" and Appendix A in this Prospectus, and
in the Statement of Additional Information.
 
  The Series may invest in a broad range of fixed income securities, including
debt securities of the U.S. government, together with its agencies and
instrumentalities and the debt securities of U.S. corporations. A majority of
the fixed income securities in which the Series will invest will possess a
minimum rating of BBB- by Standard & Poor's Ratings Group ("S&P") or Baa3 by
Moody's Investors Services, Inc. ("Moody's") or, if unrated, will be
determined to be of comparable quality by Brinson Partners. Such securities
are considered to be investment grade. Other fixed income securities in which
the Series may invest include zero coupon securities, mortgage-backed
securities, asset-backed securities and when-issued securities. The Series may
invest a portion of its assets in short-term debt securities (including
repurchase and reverse repurchase agreements) of corporations, the U.S.
government or its agencies or instrumentalities, and banks and finance
companies.
 
  The benchmark for the Series is the Salomon Brothers Broad Investment Grade
(BIG) Bond Index (the "U.S. Bond Benchmark"). The U.S. Bond Benchmark is a
market driven broad based index which includes U.S. bonds with over one year
to maturity. From time to time, the Advisor may substitute securities in an
equivalent index when it believes that such securities in the index more
accurately reflect the relevant fixed income securities market.
 
NON-U.S. EQUITY FUND
 
INVESTMENT OBJECTIVE
 
  The Non-U.S. Equity Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income, by investing primarily
in the equity securities of non-U.S. issuers. Under normal conditions, at
least 65% of the Series' total assets will be invested in equity securities of
issuers in at least three countries other than the United States. In seeking
to achieve its investment objective while controlling risk, the Series may
invest in a wide range of equity securities, including: American, European and
Global Depositary Receipts, common and preferred stock; debt securities
convertible into or exchangeable for common stock; and securities such as
warrants or rights that are convertible into common stock. The Series may
engage in futures,
 
                                      11
<PAGE>
 
options and currency transactions for hedging and other permissible purposes,
as more fully described in "Investment Considerations and Risks" and Appendix
A in this Prospectus, and in the Statement of Additional Information.
 
  The Series is a diversified portfolio that seeks to achieve its objective by
investing primarily in the equity securities of non-U.S. issuers. The
benchmark for the Series is the MSCI Non-U.S. Equity (Free) Index (the "Non-
U.S. Equity Benchmark"). The Non-U.S. Equity Benchmark is a market driven
broad based index which includes non-U.S. equity markets in terms of
capitalization and performance. From time to time, the Advisor may substitute
securities in an equivalent index when it believes that such securities in the
index more accurately reflect the relevant international market. Although it
may invest anywhere in the world, it is expected that the Series' assets will
be primarily invested in the equity markets included in the MSCI Non-U.S.
Equity (Free) Index.
 
INVESTMENT CONSIDERATIONS AND RISKS
 
  The following provides information about the types of instruments in which
the Funds may invest, strategies employed by Brinson Partners in its attempt
to attain each Series' investment objective and a summary of related risks.
Shareholders should understand that all investments involve risks and there
can be no guarantee against loss resulting from an investment in the Series,
nor can there be any assurance that the Series will be able to attain their
investment objectives. A complete list of the Series' investment restrictions
and more detailed information about the Series' investments are contained in
Appendix A in this Prospectus, and in the Statement of Additional Information.
 
  EQUITY SECURITIES (GLOBAL FUND, GLOBAL EQUITY FUND, U.S. BALANCED FUND, U.S.
EQUITY FUND, U.S. LARGE CAPITALIZATION EQUITY FUND AND NON-U.S. EQUITY FUND) -
 Equity securities fluctuate in value as a result of various factors, which
are often unrelated to the value of the issuer of the securities. These
fluctuations may be pronounced. The Global Fund may invest in small market
capitalization companies and in equity securities that are considered by the
Advisor to be in their post-venture capital stage. These securities may have
limited marketability, and therefore, may be more volatile. Fluctuations in
the value of the Series' equity investments will affect the value of their
shares and thus the Funds' total returns to investors.
 
  FIXED INCOME SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND) - All fixed income securities are subject to two types of
risks: credit risk and interest rate risk. The credit risk relates to the
ability of the issuer to meet interest or principal payments or both as they
come due. The interest rate risk refers to the fluctuations in the net asset
value of any portfolio of fixed income securities resulting from the inverse
relationship between the price and yield of fixed income securities; that is,
when the general level of interest rates rises, the prices of outstanding
fixed income securities decline, and when interest rates fall, prices rise.
 
  FOREIGN SECURITIES AND CURRENCY CONSIDERATIONS (GLOBAL FUND, GLOBAL EQUITY
FUND, GLOBAL BOND FUND AND NON-U.S. EQUITY FUND) - Investments in securities
of foreign issuers may involve greater risks than those of U.S. issuers. There
is generally less information available to the public about non-U.S. companies
and less government regulation and supervision of non-U.S. stock exchanges,
brokers and listed companies. Non-U.S. companies are not subject to uniform
global accounting, auditing and financial reporting standards, practices and
requirements. Securities of some non-U.S. companies are less liquid and their
prices more volatile than securities of comparable U.S. companies. Securities
trading practices abroad may offer less protection to investors. Settlement of
transactions in some non-U.S. markets may be delayed or may be less frequent
than in the United States, which could affect the liquidity of the Series'
portfolios. Additionally, in some non-U.S.
 
                                      12
<PAGE>
 
countries, there is the possibility of expropriation or confiscatory taxation,
limitations on the removal of securities, property or other assets of the
Series, political or social instability, or diplomatic developments which
could affect U.S. investments in those countries. The Series intend to
diversify broadly among countries, but reserve the right to invest a
substantial portion of their assets in one or more countries if economic and
business conditions warrant such investments. Brinson Partners will take these
factors into consideration in managing the Series' investments. Because the
Series will keep their books and records in U.S. dollars, the Series will be
required, for federal income tax purposes, to account for income and losses on
all transactions involving foreign currency under Section 988 of the Internal
Revenue Code of 1986, as amended, and the applicable U.S. Treasury
Regulations, so that generally any component of a gain or loss attributable to
currency fluctuations results in ordinary income or loss and not capital gain
or loss.
 
  The U.S. dollar market value of the Series' investments and of dividends and
interest earned by the Series may be significantly affected by changes in
currency exchange rates. Some currency prices may be volatile, and there is
the possibility of governmental controls on currency exchange or governmental
intervention in currency markets, which could adversely affect the Series.
Although the Series may attempt to manage currency exchange rate risks, there
is no assurance that the Series will do so at an appropriate time or that they
will be able to predict exchange rates accurately. For example, if the Series
increase their exposure to a currency and that currency's price subsequently
falls, such currency management may result in increased losses to the Series.
Similarly, if the Series decrease their exposure to a currency, and the
currency's price rises, the Series will lose the opportunity to participate in
the currency's appreciation. Each Series will manage currency exposures
relative to the normal currency allocation and will consider return and risk
of currency exposures relative to its respective Benchmark. In addition, if
the currency in which a security is denominated appreciates against the U.S.
dollar, the dollar value of the security will increase. Conversely, a decline
in the exchange rate of the currency would adversely affect the value of the
security expressed in dollars.
 
  On January 1, 1999, the European Monetary Union (the "EMU") plans to
introduce a new single currency, the Euro, which will replace the national
currencies of participating member nations. If the Series hold investments in
nations with currencies replaced by the Euro, the investment process,
including trading, foreign exchange, payments, settlements, cash accounts,
custody and accounting, will be impacted. Although it is not possible to
predict the impact of the Euro on the Series, the transition and the
elimination of currency risk among nations participating in the EMU may change
the economic environment and behavior of investors, particularly in European
markets.
 
  The adoption of the Euro does not reduce currency risk presented by
fluctuations in value of the U.S. dollar to other currencies and, in fact,
currency exchange risk may be magnified. Also, increased market volatility may
result. Additional risks that may result include the fact that European
issuers in which the Series invest may face substantial conversion costs,
which may not be accurately anticipated and may impact issuer profitability
and creditworthiness.
 
  Brinson Partners has created an interdepartmental team to handle all Euro-
related changes to enable the Series to process transactions accurately and
completely with minimal disruption to business activities. While there can be
no assurance that the Series will not be adversely affected, Brinson Partners
and the Trust's service providers are taking steps that they believe are
reasonably designed to address the Euro issue.
 
  There are additional risks inherent in investing in less developed countries
which are applicable to the Global Fund. Compared to the United States and
other developed countries, emerging market countries may have relatively
unstable governments, economies based on only a few industries, and securities
markets that trade only a small number of securities and employ settlement
procedures different from those used in the United
 
                                      13
<PAGE>
 
States. Prices on these exchanges tend to be volatile and, in the past,
securities in these countries have offered greater potential for gain (as well
as loss) than securities of companies located in developed countries. Further,
investments by foreign investors are subject to a variety of restrictions in
many emerging countries.
 
  Emerging markets countries such as those in which the Global Fund may invest
have historically experienced and may continue to experience, high rates of
inflation, high interest rates, exchange rate fluctuations or currency
depreciation, large amounts of external debt, balance of payments and trade
difficulties and extreme poverty and unemployment. Additional factors which
may influence the ability or willingness to service debt include, but are not
limited to, a country's cash flow situation, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of its debt
service burden to the economy as a whole, its government's policy towards the
International Monetary Fund, the World Bank and other international agencies
and the political constraints to which a government debtor may be subject.
 
  FOREIGN CURRENCY TRANSACTIONS (GLOBAL FUND, GLOBAL EQUITY FUND, GLOBAL BOND
FUND AND NON-U.S. EQUITY FUND) - To manage exposure to currency fluctuations,
the Series may alter fixed income or money market exposures, enter into
forward currency exchange contracts, buy or sell options or futures relating
to foreign currencies and may purchase securities indexed to currency baskets.
The Series will also use these currency exchange techniques in the normal
course of business to hedge against adverse changes in exchange rates in
connection with purchases and sales of securities. Some of these strategies
may require the Series to set aside liquid assets in a segregated custodial
account to cover their obligations.
 
  FUTURES, OPTIONS AND OTHER DERIVATIVE INSTRUMENTS (ALL SERIES) - The Series
may attempt to reduce the overall level of investment risk of particular
securities and attempt to protect against adverse market movements by
investing in futures, options and other derivative instruments. A derivative
instrument is commonly defined as a financial instrument whose performance and
value are derived, at least in part, from another source, such as the
performance of an underlying asset, a specific security or an index of
securities. The derivative instruments in which the Series may invest include
the purchase and writing of options on securities (including index options)
and options on foreign currencies, investing in futures contracts for the
purchase or sale of instruments based on financial indices, including interest
rate indices or indices of U.S. or foreign government securities, equity or
fixed income securities ("futures contracts"), forward contracts and swaps and
swap-related products such as equity index swaps, interest rate swaps,
currency swaps, and related caps, collars and floors.
 
  The investment in futures, options, forward contracts, swaps and similar
strategies by the Series will depend on Brinson Partners' judgment as to the
potential risks and rewards of different types of strategies, and it should be
recognized that the use of these instruments exposes the Series to additional
investment risks and transaction costs. If the Advisor incorrectly analyzes
the market conditions or does not employ the appropriate strategy with respect
to these instruments, the Series could be left in a less favorable position.
For example, gains and losses on investments in futures depend on the
Advisor's ability to predict correctly the direction of security prices,
interest rates and other economic factors. Additional risks inherent in the
use of futures, options and forward contracts include: adverse movements in
the prices of securities or currencies being hedged; the possible absence of a
liquid secondary market for any particular instrument at any time; and the
possible need to defer closing out certain hedge positions to avoid adverse
tax consequences. Options and futures can be volatile instruments and may not
perform as expected. A Series could experience losses if the prices of its
options and futures positions are poorly correlated with its other
investments. If a hedge is applied at an inappropriate time or price trends
are judged incorrectly, options and futures strategies may lower a Series'
return (i.e., options and futures may fail as hedging techniques in cases
where the price movements of the securities underlying the options and futures
do not follow the price movements of the portfolio securities subject to the
hedge). Options and futures traded on foreign exchanges generally are not
regulated by U.S. authorities and may offer less liquidity and less protection
to a Series in the event of default by the other party to the contract. The
loss from investing in futures
 
                                      14
<PAGE>
 
transactions is potentially unlimited. A Series does not intend to purchase
put and call options that are traded on a national stock exchange in an amount
exceeding 5% of its net assets.
 
  Each Series may invest in derivatives for hedging purposes, to maintain
liquidity, or in anticipation of changes in the composition of its portfolio
holdings. No Series will engage in derivative investments purely for
speculative purposes. A Series will invest in one or more derivatives only to
the extent that the instrument under consideration is judged by the Advisor to
be consistent with the Series' overall investment objective and policies. In
making such judgment, the potential benefits and risks will be considered in
relation to the Series' other portfolio investments.
 
  Where not specified, investment limitations with respect to a Series'
derivative instruments will be consistent with that Series' existing
percentage limitations with respect to its overall investment policies and
restrictions. The risks and policies of various types of derivative
instruments permitted for the Series, including options, futures, forward
contracts and applicable interest rate swaps, are described in greater detail
in Appendix A in this Prospectus, and in the Statement of Additional
Information.
 
  NON-DIVERSIFIED STATUS (GLOBAL BOND FUND AND U.S. LARGE CAPITALIZATION
EQUITY FUND ONLY) -- Each Series is classified as a "non-diversified"
investment company under the Act, which means that the proportion of the
Series' assets that may be invested in the securities of a single issuer is
not limited by the Act. Since each Series may invest a larger portion of its
assets in the securities of a single issuer than investment companies that are
classified as diversified funds under the Act, an investment in the Global
Bond Fund or in the U.S. Large Capitalization Equity Fund may be subject to
greater fluctuations in value than an investment in a diversified fund.
 
MANAGEMENT OF THE TRUST
 
THE BOARD OF TRUSTEES
 
  The Trust is a Delaware business trust. Under Delaware law, the Board of
Trustees has overall responsibility for managing the business and affairs of
the Trust. The Trustees elect the officers of the Trust, who are responsible
for administering the day-to-day operations of the Series.
 
THE ADVISOR
 
  Brinson Partners, a Delaware corporation, is an investment management firm,
managing as of June 30, 1998, over $286 billion, primarily for pension and
profit sharing institutional accounts. Brinson Partners and its predecessor
entities have managed domestic and international investment assets since 1974
and global investment assets since 1982. Brinson Partners has offices in
Bahrain, Basel, Frankfurt, Geneva, Hong Kong, London, Melbourne, New York,
Paris, Rio de Janeiro, Singapore, Sydney, Tokyo and Zurich, in addition to its
principal office at 209 South LaSalle Street, Chicago, IL 60604-1295. Brinson
Partners is a part of the UBS Brinson Division of UBS AG. UBS AG, with
headquarters in Basel, Switzerland, is an internationally diversified
organization with operations in many aspects of the financial services
industry. UBS AG was formed by the merger of Union Bank of Switzerland and
Swiss Bank Corporation in June 1998.
 
  Brinson Partners also serves as the investment advisor to nine other
investment companies: Brinson Relationship Funds, which includes seventeen
investment portfolios (series); The Enterprise Group of Funds, Inc. -
International Growth Portfolio; Enterprise Accumulation Trust - International
Growth Portfolio; Fort Dearborn Income Securities, Inc.; The Hirtle Callaghan
International Trust - The International Equity Portfolio; John Hancock
Variable Annuity Series Trust - International Balanced Portfolio; Managed

  Pursuant to its investment advisory agreements (the "Agreements") with the
Trust on behalf of each Series, Brinson Partners is entitled to receive a
monthly fee at various annual percentage rates of the Series' average daily
net assets, as described below, for providing investment advisory services.
Brinson Partners is responsible for paying its own expenses. Pursuant to the
Agreements, Brinson Partners is authorized, at its own expense, to obtain
statistical and other factual information and advice regarding economic
factors and trends from its foreign subsidiaries, but it does not generally
receive advice or recommendations regarding the purchase or sale of securities
from such subsidiaries.
 
  For providing investment advisory services during the fiscal year ended June
30, 1998, Brinson Partners was entitled to receive, under the Agreements, a
monthly fee at an annual rate as follows of the average daily net assets of
the Funds:
 
<TABLE>
      <S>                                                                  <C>
      Global Fund......................................................... 0.80%
      Global Equity Fund.................................................. 0.80
      Global Bond Fund.................................................... 0.75

      U.S. Bond Fund...................................................... 0.50
      Non-U.S. Equity Fund................................................ 0.80
</TABLE>
 
  The fee payable to Brinson Partners by the Global, Global Equity and Non-
U.S. Equity Funds is higher than the advisory fees paid by most other mutual
funds, but is comparable to those of other mutual funds with similar
investment objectives. The Advisor, however, has irrevocably agreed to waive
its fees and reimburse certain expenses so that the total operating expenses
of the Brinson Global Fund-Class I, Brinson Global Equity Fund-Class I,
Brinson Global Bond Fund-Class I, Brinson U.S. Balanced Fund-Class I, Brinson
U.S. Equity Fund-Class I, Brinson U.S. Large Capitalization Equity Fund-Class
I, Brinson U.S. Bond Fund-Class I and Brinson Non-U.S. Equity Fund-Class I
will never exceed 1.10%, 1.00%, 0.90%, 0.80%, 0.80%, 0.80%, 0.60% and 1.00%,
respectively.
 
PORTFOLIO MANAGEMENT
 
  Investment decisions for the Series are made by an investment management
team at Brinson Partners. No member of the investment management team is
primarily responsible for making recommendations for portfolio purchases.
 
ADMINISTRATION OF THE TRUST
 
THE UNDERWRITER
 
  Funds Distributor, Inc. ("FDI"), 60 State Street, Suite 1300, Boston, MA
02109, was engaged pursuant to an agreement dated February 5, 1997, for the
limited purpose of acting as underwriter to facilitate the filing of notices
regarding sale of the shares of the Trust under state securities laws and to
assist in the sale of shares. The fee for such service is borne by the
Advisor.
 
THE ADMINISTRATOR
 
ADMINISTRATIVE, ACCOUNTING, TRANSFER AGENCY AND CUSTODIAN SERVICES
 
  The Trust, on behalf of each Series, has entered into a Multiple Services
Agreement (the "Services Agreement") with Morgan Stanley Trust Company
("MSTC"), One Pierrepont Plaza, Brooklyn, New York 11201,
 
                                      16
<PAGE>
 
pursuant to which MSTC is required to provide general administrative,
accounting, portfolio valuation, transfer agency and custodian services to the
Series, including the coordination and monitoring of any third party service
providers.
 
  MSTC provides custodian services for the securities and cash of the Series.
The custody fee schedule is based primarily on the net amount of assets held
during the period for which payment is being made.
 
  As authorized under the Services Agreement, MSTC has entered into a Mutual
Funds Service Agreement (the "CGFSC Agreement") with Chase Global Funds
Services Company ("CGFSC"), a corporate affiliate of The Chase Manhattan Bank,
under which CGFSC provides administrative, accounting, portfolio valuation and
transfer agency services to the Series. CGFSC's business address is 73 Tremont
Street, Boston, Massachusetts 02108-3913. Subject to the supervision of the
Board of Trustees of the Trust, MSTC supervises and monitors such services
provided by CGFSC.
 
  Pursuant to the CGFSC Agreement, CGFSC provides:
 
    (1) administrative services, including providing the necessary office
  space, equipment and personnel to perform administrative and clerical
  services; preparing, filing and distributing proxy materials, periodic
  reports to investors, registration statements and other documents; and
  responding to investor inquiries;
 
    (2) accounting and portfolio valuation services, including the daily
  calculation of each Fund's net asset value and the preparation of certain
  financial statements; and
 
    (3) transfer agency services, including the maintenance of each
  investor's account records, responding to investors' inquiries concerning
  accounts, processing purchases and redemptions of each Fund's shares,
  acting as dividend and distribution disbursing agent and performing other
  service functions. Shareholder inquiries should be made to the transfer
  agent at 1-800-448-2430.
 
  Also as authorized under the Services Agreement, MSTC has entered into a
sub-administration agreement (the "FDI Agreement") with FDI under which FDI
provides administrative assistance to the Series with respect to (i)
regulatory matters, including regulatory developments and examinations, (ii)
all aspects of the Series' day-to-day operations, (iii) office facilities,
clerical and administrative services, and (iv) maintenance of books and
records.
 
  For its administrative, accounting, transfer agency and custodian services,
MSTC receives the following as compensation from the Trust on an annual basis:
0.0025% of the average daily U.S. assets of the Trust; 0.0525% of the average
daily non-U.S. assets of the Trust; 0.3250% of the average daily emerging
markets equity assets of the Trust; and 0.019% of the average daily emerging
markets debt assets of the Trust. MSTC receives an additional fee of 0.075% of
the average daily net assets of the Trust for administrative duties, the
latter subject to the expense limitation applicable to the Trust. No fee
(asset based or otherwise) is charged on any investments made by any fund into
any other fund sponsored or managed by the Advisor and assets of a fund that
are invested in another investment company or series thereof sponsored or
managed by the Advisor will not be counted in determining the 0.075%
administrative duties fee or the applicability of the expense limitation on
such fee. The foregoing fees include all out-of-pocket expenses or transaction
charges incurred by MSTC and any third party service provider in providing
such services. Pursuant to the CGFSC Agreement and the FDI Agreement, MSTC
pays CGFSC and FDI, respectively, for the services that CGFSC and FDI provide
to MSTC in fulfilling MSTC's obligations under the Services Agreement.
 
INDEPENDENT AUDITORS
 
  Ernst & Young LLP, Chicago, Illinois, are the independent auditors of the
Trust.

PURCHASE OF SHARES
 
  Shares of the Funds may be purchased directly from the Trust at the net
asset value next determined after receipt of the order in proper form by the
transfer agent. There is no sales load in connection with the purchase of Fund
shares. The Trust reserves the right to reject any purchase order and to
suspend the offering of shares of the Brinson Fund-Class I shares or any
Series. The Funds will not accept a check endorsed over by a third-party. The
minimum initial investment for Fund shares is $1,000,000. Subsequent
investments for Fund shares will be accepted in minimum amounts of $2,500. The
Trust reserves the right to vary the initial investment minimum and impose
minimums for additional investments in any of the Funds at any time. In
addition, Brinson Partners may waive the minimum initial investment
requirement for any investor.
 
  Purchase orders for shares of the Funds which are received by the transfer
agent in proper form prior to the close of regular trading hours (currently
4:00 p.m. Eastern time) on the New York Stock Exchange (the "NYSE") on any day
that the Funds' net asset values per share are calculated, are priced
according to the net asset value determined on that day. Purchase orders for
shares of the Funds received after the close of the NYSE on a particular day
are priced as of the time the net asset value per share is next determined.
The Funds reserve the right to change the time at which purchases are priced
if the NYSE closes at a time other than 4:00 p.m. Eastern time or if an
emergency exists.
 
  Under certain circumstances, the Trust has entered into one or more
agreements (each, a "Sales Agreement") with brokers, dealers or financial
institutions (each, an "Authorized Dealer") under which the Authorized Dealer
may directly, or through intermediaries that the Authorized Dealer is
authorized to designate under the Sales Agreement (each, a "Sub-designee"),
accept purchase and redemption orders that are in "good form" on behalf of the
Funds. A Fund will be deemed to have received a purchase order when the
Authorized Dealer or Sub-designee accepts the purchase order and such order
will be priced at the Fund's net asset value next computed after such order is
accepted by the Authorized Dealer or Sub-designee.
 
  The Trust may accept telephone orders for Fund shares from broker-dealers or
service organizations which have been previously approved by the Trust. It is
the responsibility of such broker-dealers or service organizations to promptly
forward purchase orders and payments for the same to the Fund. Shares of the
Funds may be purchased through broker-dealers, banks and bank trust
departments which may charge the investor a transaction fee or other fee for
their services at the time of purchase. Such fees would not otherwise be
charged if the shares were purchased directly from the Trust.
 
  Brinson Partners, or its affiliates, from its own resources, may compensate
broker-dealers or other financial intermediaries ("Service Providers") for
marketing, shareholder servicing, recordkeeping and/or other services
performed with respect to a Fund's Class I shares. Payments made for any of
these purposes may be made from its revenues, its profits or any other sources
available to it. When such service arrangements are in effect, they are made
generally available to all qualified Service Providers.

                                  anyone the shareholder designates)
                                  regular, monthly, quarterly or semi-
                                  annual payments. Each payment under a
                                  Systematic Withdrawal Plan ("SWP") must
                                  be at least $500. Such payments are
                                  drawn from share redemptions.
                                . Shareholders participating in the SWP
                                  must elect to have their dividends and
                                  distributions automatically reinvested
                                  in additional Fund shares.
                                . The Trust may terminate any SWP for an
                                  account if the value of the account
                                  falls below $50,000 as a result of
                                  share redemptions or an exchange of
                                  shares of a Fund for Brinson Fund-Class
                                  I shares of another Series of the
                                  Trust.

 INDIVIDUAL RETIREMENT ACCOUNTS . An IRA is a tax-deferred retirement
                                  savings account that may be used by an
                                  individual under age 70 1/2 who has
                                  compensation or self-employment income
                                  and his or her unemployed spouse, or an
                                  individual who has received a qualified
                                  distribution from his or her employer's
                                  retirement plan.

REDEMPTION OF SHARES
 
  Shares of the Funds may be redeemed without charge on any business day that
the NYSE is open. Redemptions will be effected at the net asset value per
share next determined after the receipt by the transfer agent of a redemption
request meeting the requirements described below. The Trust normally sends
redemption proceeds on the next business day but, in any event, redemption
proceeds are sent within five business days of receipt of a redemption request
in proper form. Payment also may be made by wire directly to any bank
previously designated by the shareholder in an Account Application. Please
note that the shareholder's bank may impose a fee for wire service. The Trust
will honor redemption requests of shareholders who recently purchased
 
                                      20
<PAGE>
 
shares by check, but will not mail the proceeds until it is reasonably
satisfied that the purchase check has cleared, which may take up to fifteen
days from the purchase date.
 
  Except as noted below, redemption requests received in proper form by the
transfer agent prior to the close of regular trading hours on the NYSE on any
business day that the Funds' net asset values per share are calculated are
effected that day. The Funds reserve the right to change the time at which
purchases are priced if the NYSE closes at a time other than 4:00 p.m. Eastern
time or if an emergency exists. Redemption requests received in proper form by
the transfer agent after the close of the NYSE are effected as of the time the
net asset value per share is next determined. No redemption will be processed
until the transfer agent has received a completed application with respect to
the account.
 
  Shares of the Funds may be redeemed through certain broker-dealers, banks
and bank trust departments who may charge the investor a transaction fee or
other fee for their services at the time of redemption. Such fees would not
otherwise be charged if the shares were redeemed directly from the Trust.
 
  Under the Sales Agreement, the Authorized Dealer or Sub-designee is
authorized to accept redemption orders on behalf of the Funds. A Fund will be
deemed to have received a redemption order when the Authorized Dealer or Sub-
designee accepts the redemption order and such order will be priced at the
Fund's net asset value next computed after such order is accepted by the
Authorized Dealer or Sub-designee.
 
  The Trust will satisfy redemption requests in cash to the fullest extent
feasible, so long as such payments would not, in the opinion of Brinson
Partners or the Board of Trustees, result in the necessity of a Series selling
assets under disadvantageous conditions and to the detriment of the remaining
shareholders of the Series. Pursuant to the Trust's Agreement and Declaration
of Trust, payment for shares redeemed may be made either in cash or in-kind,
or partly in cash and partly in-kind. However, the Trust has elected, pursuant
to Rule 18f-1 under the Act, to redeem its shares solely in cash up to the
lesser of $250,000 or 1% of the net asset value of a Series, during any 90-day
period for any one shareholder. Payments in excess of this limit will also be
made wholly in cash unless the Board of Trustees believes that economic
conditions exist which would make such a practice detrimental to the best
interests of the Series. Any portfolio securities paid or distributed in-kind
would be valued as described under "Net Asset Value." In the event that an in-
kind distribution is made, a shareholder may incur additional expenses, such
as the payment of brokerage commissions, on the sale or other disposition of
the securities received from a Series. In-kind payments need not constitute a
cross-section of a Series' portfolio. Where a shareholder has requested
redemption of all or a part of the shareholder's investment and where a Series
computes such redemption in-kind, the Series will not recognize gain or loss
for federal tax purposes on the securities used to compute the redemption, but
the shareholder will recognize gain or loss equal to the difference between
the fair market value of the securities received and the shareholder's basis
in the Fund shares redeemed.

- ----------
NOTE: The Trust reserves the right to refuse a wire or telephone redemption if
     it is believed advisable to do so. Procedures for redeeming shares of the
     Brinson Funds by wire or telephone may be modified or terminated at any
     time by the Trust.
 
TELEPHONE TRANSACTIONS:
 
  Shareholders who wish to initiate purchase, exchange or redemption
transactions by telephone must elect the option, as described above. With
respect to such telephone transactions, the Funds will ensure that reasonable
procedures are used to confirm that instructions communicated by telephone are
genuine (including verification of the shareholder's social security number or
mother's maiden name) and, if they do not, the Funds or the transfer agent may
be liable for any losses due to unauthorized or fraudulent transactions.
Written confirmation will be provided for all purchase, exchange and
redemption transactions initiated by telephone.
 
EXCHANGE OF SHARES:
 
  Fund shares may be exchanged for Brinson Fund-Class I shares of any other
Series within the Trust. Exchanges will not be permitted between the Brinson
Fund-Class I shares and either the UBS Investment Funds class of shares or the
Brinson Fund-Class N shares of a Series of the Trust.
 
  Fund shares may be exchanged by written request or by telephone if the
shareholder has previously signed a telephone authorization on the Account
Application. The telephone exchange may be difficult to implement during times
of drastic economic or market changes. The Trust reserves the right to
restrict the frequency of, or otherwise modify, condition, terminate or impose
charges upon the exchange and/or telephone transfer privileges upon 60 days'
prior written notice to shareholders.
 
  Exchanges will be made on the basis of the relative net asset value per
share of the Brinson Fund-Class I shares of the Fund from which, and the Fund
into which, the exchange is made. Exchanges may be made only for shares of a
Series and class then offering its shares for sale in your state of residence
and are subject to the
 
                                      22
<PAGE>
 
minimum initial investment requirement. For federal income tax purposes, an
exchange of shares would be treated as if the shareholder had redeemed shares
of one Series and reinvested in shares of another Series. Gains or losses on
the shares exchanged are realized by the shareholder at the time of the
exchange. Any shareholder wishing to make an exchange should first obtain and
review a prospectus of the other Series. Requests for telephone exchanges must
be received by the transfer agent by the close of regular trading hours
(currently 4:00 p.m. Eastern time) on the NYSE on any day that the NYSE is
open for regular trading. The Funds reserve the right to change the time at
which exchanges are priced if the NYSE closes at a time other than 4:00 p.m.
Eastern time or if an emergency exists.
 
TRANSFER OF SECURITIES:
 
  At the discretion of the Trust, investors may be permitted to purchase Fund
shares by transferring securities to a Series that meet the Series' investment
objective and policies. Securities transferred to a Series will be valued in
accordance with the same procedures used to determine the Fund's net asset
value at the time of the next determination of net asset value after such
acceptance. Shares issued by a Series in exchange for securities will be
issued at net asset value per share of the Fund determined as of the same
time. All dividends, interest, subscription, or other rights pertaining to
such securities shall become the property of the Series and must be delivered
to the Series by the investor upon receipt from the issuer. Investors who are
permitted to transfer such securities will be required to recognize a gain or
loss on such transfer and pay tax thereon, if applicable, measured by the
difference between the fair market value of the securities and the investors'
basis therein. Securities will not be accepted in exchange for shares of a
Fund unless: (1) such securities are, at the time of the exchange, eligible to
be included in the Series' portfolio and current market quotations are readily
available for such securities; (2) the investor represents and warrants that
all securities offered to be exchanged are not subject to any restrictions
upon their sale by the Series under the Securities Act of 1933, as amended, or
under the laws of the country in which the principal market for such
securities exists, or otherwise; and (3) the value of any such security
(except U.S. government securities) being exchanged, together with other
securities of the same issuer owned by the Series, will not exceed 5% of the
Series' net assets immediately after the transaction.
 
NET ASSET VALUE
 
  The net asset value per share for each class of shares of the Series is
computed by adding, with respect to each class of shares, the value of a
Series' investments, cash and other assets attributable to that class,
deducting liabilities of the class and dividing the result by the number of
shares of that class outstanding. The public offering price of the shares of
each classes' shares, all of which are sold on a continuous basis, is the net
asset value of that class. The valuation of assets for determining the net
asset value may be summarized as follows:
 
    Securities traded on securities exchanges are valued at the last
  available sale price. Securities that are not traded on a particular day or
  on an exchange are valued at either (a) the bid price or (b) a valuation
  within the range considered best to represent value in the circumstances.
  Price information on listed securities is generally taken from the closing
  price on the exchange where the security is primarily traded. Valuations of
  equity securities may be obtained from a pricing service and/or broker-
  dealers when such prices are believed to reflect fair value of such
  securities. Use of a pricing service and/or broker-dealers has been
  approved by the Board of Trustees. Futures contracts are valued at their
  daily quoted settlement price on the exchange on which they are traded.
  Forward foreign currency contracts are valued daily using the mean between
  the bid and asked forward points added to the current exchange rate and an
  unrealized gain or loss is recorded. The Series realizes a gain or loss
  upon settlement of the contracts. For valuation purposes, foreign
  securities initially expressed in foreign currency values will be converted
  into U.S. dollar values using WM/Reuters closing spot rates as of 4:00 p.m.
  London time.
 
                                      23
<PAGE>
 
    Securities with a remaining maturity of 60 days or less are valued at
  amortized cost, which approximates market value. Fixed income securities
  having a remaining maturity of over 60 days are valued at market price.
  Debt securities are valued on the basis of prices provided by a pricing
  service, or at the bid price where readily available, as long as the bid
  price, in the opinion of the Advisor, continues to reflect the value of the
  security. Redeemable securities issued by open-end investment companies are
  valued using their respective net asset values for purchase orders placed
  at the close of the NYSE. Securities (including over-the-counter options)
  for which market quotations are not readily available and other assets are
  valued at their fair value as determined in good faith by or under the
  direction of the Trustees.
 
  Net asset value is determined on each day that the NYSE is open, as of the
close of business of the regular session of the NYSE (currently 4:00 p.m.
Eastern time). Investments and requests to exchange or redeem shares received
by the Series in proper form before such close of business are effective, and
will receive the price determined, on that day. Investment, exchange and
redemption requests received after such close of business are effective, and
will receive the share price determined, on the next business day. The Funds
reserve the right to change the time at which purchases, redemptions and
exchanges are priced if the NYSE closes at a time other than 4:00 p.m. Eastern
time or if an emergency exists.
 
  Because of time zone differences, foreign exchanges and securities markets
will usually be closed prior to the time of the closing of the NYSE and values
of foreign futures and options and foreign securities will be determined as of
the earlier closing of such exchanges and securities markets. However, events
affecting the values of such foreign securities may occasionally occur between
the earlier closings of such exchanges and securities markets and the closing
of the NYSE which will not be reflected in the computation of the net asset
value of a class of a Series. If an event materially affecting the value of
such foreign securities occurs during such period, then such securities will
be valued at fair value as determined in good faith by or under the direction
of the Board of Trustees. Where a foreign securities market remains open at
the time that a Series values its portfolio securities, or closing prices of
securities from that market may not be retrieved because of local time
differences or other difficulties in obtaining such prices at that time, last
sale prices in such market at a point in time most practicable to timely
valuation of the Series may be used.
 
  The Series' portfolio securities from time to time may be listed primarily
on foreign exchanges which trade on days when the NYSE is closed (such as
Saturday). As a result, the net asset value of a class of a Fund may be
significantly affected by such trading on days when shareholders have no
access to the Fund.
 
  All of the Series' classes of shares will bear pro rata all of the expenses
of that Series common to all classes. The net asset value of all outstanding
shares of each class of the Series will be computed on a pro rata basis for
each outstanding share based on the proportionate participation in the Series
represented by the value of shares of that class. All income earned and
expenses incurred by the Series will be borne on a pro rata basis by each
outstanding share of a class, based on each class' proportionate participation
in the Series represented by the value of shares of such class, except that
the Brinson Fund-Class N and UBS Investment Funds class of shares will bear
12b-1 expenses payable under their respective 12b-1 plans.
 
  Due to the specific distribution expenses and other costs that will be
allocable to each class, the dividends paid to each class, and related
performance, of the Series may vary. The per share net asset value of the
Brinson Fund-Class N shares and the UBS Investment Funds class of shares will
generally be lower than that of the Brinson Fund-Class I shares of a Series
because of the higher expenses borne by the UBS Investment Funds class of
shares and the Brinson Fund-Class N shares. It is expected, however, that the
net asset value per share of the two classes will tend to converge immediately
after the payment of dividends, which will differ by approximately the amount
of the service and distribution expenses differential among the classes.

DIVIDENDS, DISTRIBUTIONS AND TAXES
 
DIVIDENDS
 
  The Series will distribute their net investment income semi-annually in June
and December. The Series will distribute annually in December substantially
all of their net long-term capital gains and any undistributed net short-term
capital gains realized during the one year period commencing November 1 (or
date of the creation of the Series, if later) and ending October 31, and, at
the same time, will distribute all of their net investment income earned
through the end of December and not previously distributed as ordinary (not
capital) income.
 
  Dividends and other distributions paid by a Series with respect to its
Brinson Fund-Class N, Brinson Fund-Class I and UBS Investment Funds class of
shares are calculated in the same manner and at the same time. The per share
amount of any income dividends will generally differ among the classes only to
the extent that the Brinson Fund-Class N and UBS Investment Fund class of
shares are subject to separate 12b-1 fees. The per share dividends on UBS
Investment Funds class of shares and Brinson Fund-Class N shares will be lower
than the per share dividends on the Brinson Fund-Class I shares of each Series
as a result of the distribution and service fees applicable with respect to
the UBS Investment Funds class of shares and Brinson Fund-Class N shares.
 
  Income dividends and capital gain distributions are reinvested automatically
in additional Fund shares of the same class of a Series at net asset value,
unless the shareholder has notified the transfer agent, in writing, of the
shareholder's election to receive them in cash. Distribution options may be
changed at any time by requesting a change in writing. Any check in payment of
dividends or other distributions which cannot be delivered by the Post Office
or which remains uncashed for a period of more than one year may be reinvested
in the shareholder's account at the then current net asset value and the
dividend option may be changed from cash to reinvest. Dividends are reinvested
on the ex dividend date (the "ex date") at the net asset value determined at
the close of business on that date. Please note that shares purchased shortly
before the record date for a dividend or distribution may have the effect of
returning capital although such dividends and distributions are subject to
taxes.
 
TAXES
 
  Each Series has qualified, and intends to continue to qualify, for taxation
as a "regulated investment company" under the Internal Revenue Code of 1986,
as amended ("the Code"). Such qualification relieves a Series of liability for
federal income taxes to the extent the Series' earnings are distributed in
accordance with the Code. Each Series is treated as a separate corporate
entity for federal tax purposes.
 
  Distributions of any net investment income and of any net realized short-
term capital gains are taxable to shareholders as ordinary income. All
distributions may be subject to state and local taxes.
 
  Distributions of net capital gain (the excess of net long-term capital gain
over net short-term capital loss) are taxable to shareholders as long-term
capital gain regardless of how long a shareholder may have held shares of a
Series. The tax treatment of distributions of ordinary income or capital gains
will be the same whether the shareholder reinvests the distributions or elects
to receive them in cash. A distribution will be treated as paid on December 31
of the current calendar year if it is declared in October, November or
December with a record date in such a month and paid during January of the
following calendar year. Such distributions will be taxable to shareholders in
the calendar year in which the distributions are declared, rather than the
calendar year in which the distributions are received.
 
  Shareholders will be advised annually of the source and tax status of all
distributions for federal income tax purposes. Further information regarding
the tax consequences of investing in the Series is included in the
 
                                      25
<PAGE>
 
Statement of Additional Information. The above discussion is intended for
general information only. Investors should consult their own tax advisors for
more specific information on the tax consequences of particular types of
distributions.
 
  Redemptions of Series shares, and the exchange of shares between two Series
of the Trust, are taxable events and, accordingly, shareholders may realize
capital gains or losses on these transactions.
 
  Shareholders may be subject to back-up withholding on reportable dividend
and redemption payments ("back-up withholding") if a certified taxpayer
identification number is not on file with the Series, or if, to the Series'
knowledge, an incorrect number has been furnished, or if the Series has been
notified by the Internal Revenue Service that an account is subject to back-up
withholding. An individual's taxpayer identification number is the
individual's social security number.
 
  If more than 50% of a Series' total assets at the close of its taxable year
consists of stock or securities in foreign corporations, the Series may elect
to "pass-through" to shareholders for foreign tax credit purposes the amount
of foreign income taxes paid by the Series with respect to its direct holdings
of securities in foreign corporations. A Series will make such an election
only if it deems such election to be in the best interests of its
shareholders. If this election is made, shareholders of the Series will be
required to include in their gross incomes their pro rata share of foreign
taxes paid by the Series. However, shareholders will be able to treat their
pro rata share of foreign taxes as either a deduction (itemized deduction in
the case of individuals) or a foreign tax credit (but not both) against U.S.
income taxes on their tax returns. A Series which makes investments in the
securities of foreign corporations may make investments in foreign companies
that are "passive foreign investment companies" ("PFICs"). These investments
in PFICs may cause a Series to pay income taxes and interest charges. If
possible, the Series will not invest in PFICs or will adopt other strategies
to avoid these taxes and charges.
 
GENERAL INFORMATION
 
ORGANIZATION
 
  The Brinson Funds is a Delaware business trust organized pursuant to an
Agreement and Declaration of Trust, dated December 1, 1993. The Trust was
originally organized as a Maryland corporation on April 14, 1992. On December
1, 1993, the Trust reorganized as a Delaware business trust through a merger
of the Maryland corporation into the Trust. The Trust is registered under the
Act as an open-end management investment company, commonly known as a mutual
fund and consists of eight different Series. The Trustees of the Trust may
establish additional series or classes of shares without the approval of
shareholders. All of the Series, except the Global Bond Fund, are diversified
portfolios. The assets of each Series belong only to that Series, and the
liabilities of each Series are borne solely by that Series and no other.
 
DESCRIPTION OF SHARES
 
  Each Series is authorized to issue an unlimited number of shares of
beneficial interest with a $0.001 par value per share. The Board of Trustees
has the power to designate one or more series or sub-series/classes of shares
of beneficial interest and to classify or reclassify only unissued shares with
respect to such series. Shares of each series represent equal proportionate
interests in the assets of that series only and have identical voting,
dividend, redemption, liquidation, and other rights, except that only shares
of each Series' Brinson Fund-Class N and UBS Investment Fund classes shall
have voting rights with respect to the Rule 12b-1 plan relating to such
 
                                      26

classes, respectively, as described below. All shares issued are fully paid
and non-assessable, and shareholders have no preemptive or other right to
subscribe to any additional shares and no conversion rights. Currently, the
Trust offers eight investment portfolios or series-Global Fund, Global Equity
Fund, Global Bond Fund, U.S. Balanced Fund, U.S. Equity Fund, U.S. Large
Capitalization Equity Fund, U.S. Bond Fund and Non-U.S. Equity Fund. Three
classes of shares are currently issued by the Trust for each Series, the
Brinson Fund-Class N, Brinson Fund-Class I and UBS Investment Fund class.
Prior to September 15, 1998, the "UBS Investment Funds class" of shares was
known as the "SwissKey Fund class."
 
VOTING RIGHTS
 
  Each issued and outstanding full and fractional share of a Series is
entitled to one full and fractional vote in the Series and all shares of each
Series participate equally with regard to dividends, distributions, and
liquidations with respect to that Series. Shareholders do not have cumulative
voting rights. On any matter submitted to a vote of shareholders, shares of
each Series will vote separately except when a vote of shareholders in the
aggregate is required by law, or when the Trustees have determined that the
matter affects the interests of more than one Series, in which case the
shareholders of all such Series shall be entitled to vote thereon. Only the
Brinson Fund-Class N shareholders may vote on matters related to the Rule 12b-
1 plan associated with that class and only the UBS Investment Fund class
shareholders may vote on matters related to the Rule 12b-1 plan associated
with that class.
 
  As of August 18, 1998, Wachovia Bank NA held of record more than 25% of the
outstanding shares of the Global Equity Fund; Wilmington Trust Co. held of
record more than 25% of the outstanding shares of the Global Bond Fund; MAC &
Co. held of record more than 25% of the outstanding shares of the U.S.
Balanced Fund; Norwest MN held of record more than 25% of the outstanding
shares of the U.S. Large Capitalization Equity Fund; Wachovia Bank NA held of
record more than 25% of the outstanding shares of the U.S. Bond Fund; The
Northern Trust Co. held of record more than 25% of the outstanding shares of
the Non-U.S. Equity Fund. A shareholder that holds such a percentage of the
outstanding shares of a class may be deemed a controlling person of that class
under the Act.
 
SHAREHOLDER MEETINGS
 
  The Trustees of the Trust do not intend to hold annual meetings of
shareholders of the Series. The SEC, however, requires the Trustees to
promptly call a meeting for the purpose of voting upon the question of removal
of any Trustee when requested to do so by not less than 10% of the outstanding
shareholders of the respective Series. In addition, subject to certain
conditions, shareholders of each Series may apply to the Series to communicate
with other shareholders to request a shareholders' meeting to vote upon the
removal of a Trustee or Trustees.
 
PORTFOLIO TURNOVER (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND AND U.S.
BOND FUND)
 
  As a result of the investment policies of the Global Fund, Global Bond Fund,
U.S. Balanced Fund and U.S. Bond Fund, their portfolio turnover rates may
exceed 100%. High portfolio turnover (over 100%) may involve correspondingly
greater brokerage commissions and other transaction costs, which will be borne
directly by the Series and ultimately by the Series' shareholders. In
addition, high portfolio turnover may result in increased short-term capital
gains, which, when distributed to shareholders, are treated as ordinary income
for tax purposes.
 
                                      27
<PAGE>
 
PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS
 
  The Trust will attempt to obtain the best overall price and most favorable
execution of transactions in portfolio securities. However, subject to
policies established by the Board of Trustees of the Trust, a Series may pay a
broker-dealer a commission for effecting a portfolio transaction for the
Series in excess of the amount of commission another broker-dealer would have
charged if Brinson Partners determines in good faith that the commission paid
was reasonable in relation to the brokerage or research services provided by
such broker-dealer, viewed in terms of that particular transaction or such
firm's overall responsibilities with respect to the clients, including the
Series, as to which it exercises investment discretion. In selecting and
monitoring broker-dealers and negotiating commissions, consideration will be
given to a broker-dealer's reliability, the quality of its execution services
on a continuing basis and its financial condition.
 
  When buying or selling securities, the Series may pay commissions to brokers
who are affiliated with the Advisor or the Series. The Series may purchase
securities in certain underwritten offerings for which an affiliate of the
Series or the Advisor may act as an underwriter. The Series may effect futures
transactions through, and pay commissions to, futures commission merchants who
are affiliated with the Advisor or the Series in accordance with procedures
adopted by the Board of Trustees of the Trust.
 
SHAREHOLDER REPORTS AND INQUIRIES
 
  Shareholders will receive semi-annual reports showing portfolio investments
and other information as of December 31 and annual reports audited by
independent auditors as of June 30. Shareholders with inquiries should call
The Brinson Funds at 1-800-448-2430 or write to The Brinson Funds, P.O. Box
2798, Boston, MA 02208-2798.
 
YEAR 2000 ISSUES
 
  Like other investment companies, as well as other financial and business
organizations around the world, the Trust could be adversely affected if the
computer systems used by the Advisor, MSTC, CGFSC and other service providers,
in performing their administrative functions for the Trust, do not properly
process and calculate date-related information and data as of and after
January 1, 2000. This is commonly known as the "Year 2000 Issue." The Year
2000 Issue, and, in particular, foreign service providers' responsiveness to
the issue, could affect portfolio and operational areas including securities
trade processing, interest and dividend payments, securities pricing,
shareholder account services, custody functions and others. The Advisor, MSTC
and CGFSC are taking steps that they believe are reasonably designed to
address the Year 2000 Issue with respect to computer systems that they use and
to obtain reasonable assurances that comparable steps are being taken by the
Trust's other service providers. These include identifying those systems that
may not function properly after December 31, 1999, and correcting or replacing
those systems. In addition, steps include testing the processing of Series
data on all systems relied on by the Advisor, MSTC and CGFSC. As of the date
of this Prospectus, however, there can be no assurance that these steps will
be sufficient to avoid any adverse impact to the Series.
 
PERFORMANCE INFORMATION
 
  From time to time, performance information, such as yield or total return,
may be quoted in advertisements or in communications to present or prospective
shareholders. Performance quotations represent the Funds' past performance and
should not be considered as representative of future results. The current
yield will be calculated by dividing the net investment income earned per
share by a Fund during the period stated in the advertisement (based on the
average daily number of shares entitled to receive dividends outstanding
during the period) by the
 
                                      28
<PAGE>
 
maximum net asset value per share on the last day of the period and
annualizing the result on a semi-annual compounded basis. The Funds' total
return may be calculated on an annualized and aggregate basis for various
periods (which periods will be stated in the advertisement). Average annual
return reflects the average percentage change per year in value of an
investment in a Fund. Aggregate total return reflects the total percentage
change over the stated period.
 
  To help investors better evaluate how an investment in the Brinson Funds
might satisfy their investment objectives, advertisements regarding the Funds
may discuss yield or total return as reported by various financial
publications. Advertisements may also compare yield or total return to other
investments, indices and averages. The following publications, benchmarks,
indices and averages may be used: Lipper Mutual Fund Performance Analysis;
Lipper Fixed Income Analysis; Lipper Mutual Fund Indices; Morgan Stanley
Indices; Lehman Brothers Treasury Index; Salomon Brothers Indices; Dow Jones
Composite Average or its component indices; Standard & Poor's 500 Stock Index
or its component indices; Wilshire Indices; The New York Stock Exchange
composite or component indices; CDA Mutual Fund Report; Weisenberger-Mutual
Funds Panorama and Investment Companies; Mutual Fund Values and Mutual Fund
Service Book, published by Morningstar, Inc.; comparable portfolios managed by
the Advisor; and financial publications, such as Business Week, Kiplinger's
Personal Finance, Financial World, Forbes, Fortune, Money Magazine, The Wall
Street Journal, Barron's, et al., which rate fund performance over various
time periods.
 
  The principal value of an investment in the Funds will fluctuate, so that an
investor's shares, when redeemed, may be worth more or less than their
original cost. Any fees charged by banks or other institutional investors
directly to their customer accounts in connection with investments in shares
of the Funds will not be included in the Brinson Funds' calculations of yield
or total return. Further information about the performance of the Funds is
included in the Funds' Annual Report dated June 30, 1998, which may be
obtained without charge by contacting the Trust at 1-800-448-2430.

APPENDIX A
 
INVESTMENT POLICIES AND TECHNIQUES
 
  EQUITY SECURITIES (GLOBAL FUND, GLOBAL EQUITY FUND, U.S. BALANCED FUND, U.S.
EQUITY FUND, U.S. LARGE CAPITALIZATION EQUITY FUND AND NON-U.S. EQUITY FUND):
The Series may invest in a broad range of equity securities of U.S. and non-
U.S. issuers, including common stocks of companies or closed-end investment
companies, preferred stocks, debt securities convertible into or exchangeable
for common stock, securities such as warrants or rights that are convertible
into common stock and sponsored or unsponsored American, European and Global
depositary receipts ("Depositary Receipts"). The issuers of unsponsored
Depositary Receipts are not obligated to disclose material information in the
United States. The Series expect their U.S. equity investments to emphasize
large and intermediate capitalization companies, although the Global Fund may
also invest in small capitalization equity markets. The equity markets in the
non-U.S. component of the Series will typically include available shares of
larger capitalization companies. Capitalization levels are measured relative
to specific markets, thus large, intermediate and small capitalization ranges
vary country by country. The Global Fund may invest in equity securities of
companies considered by the Advisor to be in their post-venture capital stage,
or "post-venture capital companies." A post-venture capital company is a
company that has received venture capital financing either (a) during the
early stages of the company's existence or the early stages of the development
of a new product or service, or (b) as part of a restructuring or
recapitalization of the company. The Global Fund also may invest in open-end
investment companies advised by Brinson Partners, in equity securities of
issuers in emerging markets and in securities with respect to which the return
is derived from the equity securities of issuers in emerging markets.
 
  FIXED INCOME SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND): The Series may invest in a broad range of fixed income
securities of U.S. and non-U.S. issuers, including governments and
governmental entities, supranational issuers as well as corporations and other
business organizations. The Series may purchase U.S. dollar denominated
securities that reflect a broad range of investment maturities, qualities and
sectors. A majority of the fixed income securities in which the Series will
invest will possess a minimum rating of BBB- by S&P or Baa3 by Moody's or, if
unrated, will be determined to be of comparable quality by Brinson Partners.
Such securities are considered to be investment grade. While securities rated
BBB- or Baa3 are regarded as having an adequate capacity to pay principal and
interest, such bonds lack outstanding investment characteristics and, in fact,
have speculative characteristics; and changes in economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than is the case with higher rated bonds. Securities
rated lower than BBB- by S&P and Baa3 by Moody's are classified as non-
investment grade securities (commonly referred to as "junk bonds"), carry a
higher degree of risk and are considered to be speculative by the major credit
rating agencies. Each Series currently intends to limit its aggregate
investment in non-investment grade debt securities of its U.S. and non-U.S.
dollar denominated fixed income assets to no more than 5% of its net assets.
To the extent that a security held by a Series is downgraded to below
investment grade, the Series will dispose of that or another non-investment
grade security so that no more than 5% of its assets will be invested in below
investment grade securities. Other fixed income securities in which the Series
may invest include zero coupon securities, mortgage-backed securities, asset-
backed securities and when-issued securities.
 
  The non-U.S. fixed income component of the Series will typically be invested
in the securities of non-U.S. governments, governmental agencies and
supranational issues. A supranational entity is an entity established or
financially supported by the national governments of one or more countries to
promote reconstruction or development. Examples of supranational entities
include, among others: the World Bank, the European
 
                                      30
<PAGE>
 
Economic Community, the European Coal and Steel Community, the European
Investment Bank, the Inter-American Development Bank, the Export-Import Bank
and the Asian Development Bank.
 
  The Global Fund may invest in fixed income securities of emerging market
issuers, including government and government-related entities (including
participation in loans between governments and financial institutions), and of
entities organized to restructure outstanding debt securities of developing
countries' corporate issuers.
 
  CASH AND CASH EQUIVALENTS (ALL SERIES): The Series may invest a portion of
their assets in short-term debt securities (including repurchase agreements
and reverse repurchase agreements) of corporations, the U.S. government and
its agencies and instrumentalities and banks and finance companies, which may
be denominated in any currency. When unusual market conditions warrant, a
Series may make substantial temporary defensive investments in cash
equivalents up to a maximum of 100% of its net assets. Cash equivalent
holdings may be in any currency (although such holdings may not constitute
"cash or cash equivalents" for tax diversification purposes under the Code).
When a Series invests for defensive purposes, it may affect the attainment of
the Series' investment objective.
 
  Under the terms of an exemptive order issued by the SEC, each Series may
invest cash (i) held for temporary defensive purposes; (ii) not invested
pending investment in securities; (iii) that is set aside to cover an
obligation or commitment of the Series to purchase securities or other assets
at a later date; (iv) to be invested on a strategic management basis (i-iv is
herein referred to as "Uninvested Cash"); and (v) collateral that it receives
from the borrowers of its portfolio securities in connection with the Series'
securities lending program, in a series of shares of Brinson Supplementary
Trust (the "Supplementary Trust Series"). Brinson Supplementary Trust is a
private investment company which has retained the Advisor to manage its
investments. The Trustees of the Trust also serve as Trustee of the Brinson
Supplementary Trust. The Supplementary Trust Series will invest in U.S. dollar
denominated money market instruments having a dollar-weighted average maturity
of 90 days or less. A series' investment of Uninvested Cash in shares of the
Supplementary Trust Series will not exceed 25% of the Series' total assets. In
the event that the Advisor waives 100% of its investment advisory fee with
respect to a Series, as calculated monthly, then that series will be unable to
invest in the Supplementary Trust Series until additional investment advisory
fees are owed by the Series.
 
  ZERO COUPON SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND): Zero coupon securities are debt obligations which do not
entitle the holder to any periodic payments of interest prior to maturity or a
specified date when the securities begin paying current interest (the "cash
payment date") and, therefore, are issued and traded at a discount from their
value at maturity or par value. Such bonds carry an additional risk in that,
unlike bonds which pay interest throughout the period to maturity, a Series
investing in zero coupon securities will realize no cash until the cash
payment date and, if the issuer defaults, a Series may obtain no return at all
on its investment. The market price of zero coupon securities generally is
more volatile than the market price of securities that pay interest
periodically and are likely to be more responsive to changes in interest rates
than non-zero coupon securities having similar maturities and credit
qualities. For federal tax purposes, the Series will be required to include in
income daily portions of original issue discount accrued and to distribute the
same to shareholders annually, even if no payment is received before the
distribution date.
 
  MORTGAGE- AND ASSET-BACKED SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S.
BALANCED FUND AND U.S. BOND FUND): Mortgage-backed securities represent direct
or indirect participations in, or are secured by and payable from, pools of
mortgage loans secured by real property, and include single- and multi-class
pass-through securities and collateralized mortgage obligations. These
securities may be issued or guaranteed by agencies or instrumentalities of the
U.S. government. Other mortgage-backed securities are issued by private
 
                                      31
<PAGE>
 
issuers, generally originators of and investors in mortgage loans, including
savings associations, mortgage bankers, commercial banks, investment bankers
and special purpose entities (collectively, "private lenders"). Mortgage-
backed securities issued by private lenders may be supported by pools of
mortgage loans or other mortgage-backed securities that are guaranteed,
directly or indirectly, by the U.S. government or one of its agencies or
instrumentalities, or they may be issued without any governmental guarantee of
the underlying mortgage assets but with some form of non-governmental credit
enhancement.
 
  Asset-backed securities have structural characteristics similar to mortgage-
backed securities. However, the underlying assets are not first-lien mortgage
loans or interests therein; rather, they include assets such as motor vehicle
installment sales contracts, other installment loan contracts, home equity
loans, leases of various types of property and receivables from credit card or
other revolving credit arrangements. Payments or distributions of principal
and interest on asset-backed securities may be supported by non-governmental
credit enhancements similar to those utilized in connection with mortgage-
backed securities.
 
  The yield characteristics of mortgage- and asset-backed securities differ
from those of traditional debt obligations. Among the principal differences
are that interest and principal payments are made more frequently on mortgage-
and asset-backed securities, usually monthly, and that principal may be
prepaid at any time because the underlying mortgage loans or other assets
generally may be prepaid at any time. As a result, the rate of return on these
securities may be affected by prepayments of principal on the underlying
loans, which generally increase as interest rates decline. As a result, if a
Series purchases these 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 a Series purchases these securities at a discount,
a prepayment rate that is faster than expected will increase yield to
maturity, while a prepayment rate that is slower than expected will reduce
yield to maturity. Accelerated prepayments on securities purchased by a Series
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 prepaid in full. In
addition, like other debt securities, the values of mortgage-related
securities, including government and government-related mortgage pools,
generally will fluctuate in response to market interest rates. The market for
privately issued mortgage- and asset-backed securities is smaller and less
liquid than the market for government sponsored mortgage-backed securities.
 
  WHEN-ISSUED SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND): The Series may purchase securities on a "when-issued"
basis for payment and delivery at a later date. The price is generally fixed
on the date of commitment to purchase. During the period between purchase and
settlement, no interest accrues to a Series. At the time of settlement, the
market value of the security may be more or less than the purchase price. The
Series will establish a segregated account consisting of cash, U.S. government
securities, equity securities and/or investment and non-investment grade debt
securities in accordance with SEC positions. The cash, U.S. government
securities, equity securities, investment or non-investment grade debt
securities and other assets held in any segregated account maintained by the
Series with respect to any when-issued securities, options, futures, forward
contracts or other derivative transactions shall be liquid, unencumbered and
marked-to-market daily (the assets held in a segregated account are referred
to in this Prospectus as "Segregated Assets"), and such Segregated Assets
shall be maintained in accordance with pertinent SEC positions.
 
  FOREIGN CURRENCY TRANSACTIONS (GLOBAL FUND, GLOBAL EQUITY FUND, GLOBAL BOND
FUND AND NON-U.S. EQUITY FUND): The Series may conduct their foreign currency
exchange transactions on a spot (i.e., cash) basis at the spot rate prevailing
in the foreign currency exchange market or through entering into contracts to
purchase or sell foreign currencies at a future date (i.e., a "forward foreign
currency" contract or "forward" contract). A forward contract involves an
obligation to purchase or sell a specific currency amount at a future date,
which
 
                                      32
<PAGE>
 
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. The Series will
convert currency on a spot basis from time to time and investors should be
aware that changes in currency exchange rates and exchange control regulations
may affect the costs of currency conversion.
 
  The Series may enter into forward contracts for hedging purposes as well as
non-hedging purposes. For hedging purposes, a Series may enter into contracts
to deliver or receive foreign currency it will receive from or require for its
normal investment activities. It may also use contracts in a manner intended
to protect foreign currency-denominated securities from declines in value due
to unfavorable exchange rate movements. A Series may also enter into contracts
with the intent of changing the relative exposure of the Series' portfolio of
securities to different currencies to take advantage of anticipated changes in
exchange rates.
 
  When a Series enters into forward contracts for non-hedging purposes, it
will establish a segregated account with its custodian bank in which it will
maintain Segregated Assets in accordance with SEC positions.
 
  At the maturity of a forward contract, a Series may either sell a portfolio
security and make delivery of the foreign currency, or it may retain the
security and terminate its contractual obligation to deliver the foreign
currency by purchasing an "offsetting" contract with the same currency trader,
obligating it to purchase, on the same maturity date, the same amount of the
foreign currency. A Series may realize a gain or loss from currency
transactions.
 
  OPTIONS ON CURRENCIES (GLOBAL FUND, GLOBAL EQUITY FUND, GLOBAL BOND FUND AND
NON-U.S. EQUITY FUND): The Series also may purchase and write put and call
options on foreign currencies (traded on U.S. and foreign exchanges or over-
the-counter markets) to manage the respective portfolio's exposure to changes
in currency exchange rates. Call options on foreign currency written by a
Series will be "covered," which means that the Series will own an equal amount
of, or an offsetting position in, the underlying foreign currency. With
respect to put options on foreign currency written by a Series, the Series
will establish a segregated account with its custodian bank consisting of
Segregated Assets equal in accordance with SEC positions.
 
  FUTURES CONTRACTS (ALL SERIES): The Series may enter into contracts for the
future purchase or sale of securities and indices. The Global Funds and the
Non-U.S. Equity Fund also may enter into contracts for the future purchase or
sale of foreign currencies. A financial futures contract is an agreement
between two parties to buy or sell a specified debt security at a set price on
a future date. An index futures contract is an agreement to take or make
delivery of an amount of cash based on the difference between the value of the
index at the beginning and at the end of the contract period. A futures
contract on a foreign currency is an agreement to buy or sell a specified
amount of a currency for a set price on a future date. A Series may enter into
a futures contract to the extent that not more than 5% of its assets are
required as futures contract margin deposits and its obligations relating to
such futures transactions represent not more than 25% of the Series' assets.
The Series may also effect futures transactions through futures commission
merchants who are affiliated with the Advisor or the Series in accordance with
procedures adopted by the Board of Trustees.
 
  The Global Fund, Global Equity Fund, Global Bond Fund and Non-U.S. Equity
Fund will enter into such futures transactions on domestic exchanges and, to
the extent such transactions have been approved by the Commodity Futures
Trading Commission for sale to customers in the United States, on foreign
exchanges.
 
  OPTIONS (ALL SERIES): The Series may purchase and write put and call options
on foreign or U.S. securities and indices and enter into related closing
transactions. A Series' may use options traded on U.S. exchanges and, to the
extent permitted by law, options traded over-the-counter and recognized
foreign exchanges. It is the
 
                                      33
<PAGE>
 
position of the U.S. Securities and Exchange Commission that over-the-counter
options are illiquid. Accordingly, a Series will invest in such options only
to the extent consistent with its 15% limit on investment in illiquid
securities.
 
  REPURCHASE AGREEMENTS (ALL SERIES): The Series may enter into repurchase
agreements with banks or broker-dealers. Repurchase agreements are considered
under the Act to be collateralized loans by a Series to the seller secured by
the securities transferred to the Series. Repurchase agreements under the Act
will be fully collateralized by securities which the Series may invest in
directly. Such collateral will be marked-to-market daily. If the seller of the
underlying security under the repurchase agreement should default on its
obligation to repurchase the underlying security, the Series may experience
delay or difficulty in recovering its cash. To the extent that, in the
meantime, the value of the security purchased had decreased, the Series could
experience a loss. No more than 15% of a Series' net assets will be invested
in illiquid securities, including repurchase agreements which have a maturity
of longer than seven days. The Series must treat each repurchase agreement as
a security for tax diversification purposes and not as cash, a cash equivalent
or as a receivable.
 
  BORROWING (ALL SERIES): Each Series is authorized, within specified limits,
to borrow money as a temporary defensive measure for extraordinary purposes
and to pledge its assets in connection with such borrowings.
 
  LOANS OF PORTFOLIO SECURITIES (ALL SERIES): Each Series may loan its
portfolio securities to broker-dealers and other institutional investors
pursuant to agreements requiring that the loans be continuously secured by
collateral equal at all times in value to at least the market value of the
securities loaned. The major risk to which a Series would be exposed on a loan
transaction is the risk that the borrower would become bankrupt at a time when
the value of the security goes up. Therefore, a Series will only enter into
loan arrangements after a review of all pertinent factors by Brinson Partners,
subject to overall supervision by the Board of Trustees, including the
creditworthiness of the borrowing broker-dealer or institution and then only
if the consideration to be received from such loans would justify the risk.
Creditworthiness will be monitored on an ongoing basis by Brinson Partners.
 
  RULE 144A AND ILLIQUID SECURITIES (ALL SERIES): Each Series may invest up to
15% of its net assets in illiquid securities. Illiquid securities are those
securities that are not readily marketable, including restricted securities
and repurchase obligations that mature in more than seven days. Certain
restricted securities that may be resold to institutional investors pursuant
to Rule 144A under the Securities Act of 1933 may be determined to be liquid
under guidelines adopted by the Trust's Board of Trustees.
 
  INVESTMENT COMPANY SECURITIES (GLOBAL FUND): The Trust has received an
exemptive order (the "Exemptive Order") from the SEC which permits each Series
to invest its assets in certain portfolios of Brinson Relationship Funds,
another registered investment company advised by Brinson Partners. Currently,
only the Global Fund intends to invest in the portfolios of Brinson
Relationship Funds and only to the extent consistent with Brinson Partners'
investment process of allocating assets to specific asset classes. The Global
Fund will invest in the portfolios of Brinson Relationship Funds to obtain
exposure to the following asset classes: (1) equity and fixed income
securities of issuers located in emerging market countries ("Emerging Market
Securities"); (2) equity securities issued by companies with relatively small
overall market capitalizations ("Small Cap Securities"); and (3) high yield
securities ("High Yield Securities"). The Global Fund will invest in
corresponding portfolios of Brinson Relationship Funds only to the extent the
Advisor determines that such investments are a more efficient means for the
Global Fund to gain exposure to the asset classes identified above than by
investing directly in individual securities. Thus, to gain exposure to
Emerging Market Securities, the Global Fund will invest in the Brinson
Emerging Markets Equity Fund and the Brinson Emerging Markets Debt Fund
portfolios of Brinson Relationship Funds. To gain exposure to Small Cap
Securities and High Yield Securities, the Global Fund will
 
                                      34
<PAGE>
 
invest in the Brinson Post-Venture Fund and the Brinson High Yield Fund
portfolios, respectively, of Brinson Relationship Funds. Each portfolio of
Brinson Relationship Funds in which the Global Fund may invest is permitted to
invest in the same securities of a particular asset class in which the Global
Fund is permitted to invest directly, and with similar risks.
 
  RUSSIAN SECURITIES (GLOBAL FUND): The Series may invest in securities of
Russian companies. The registration, clearing and settlement of securities
transactions in Russia are subject to significant risks not normally
associated with securities transactions in the United States and other more
developed markets. Ownership of shares of Russian companies is evidenced by
entries in a company's share register (except where shares are held through
depositories that meet the requirements of the Act) and the issuance of
extracts from the register or, in certain limited cases, by formal share
certificates. However, Russian share registers are frequently unreliable and
the Series could possibly lose its registration through oversight, negligence
or fraud. Moreover, Russia lacks a centralized registry to record securities
transactions and registrars located throughout Russia or the companies
themselves maintain share registers. Registrars are under no obligation to
provide extracts to potential purchasers in a timely manner or at all and are
not necessarily subject to state supervision. In addition, while registrars
are liable under law for losses resulting from their errors, it may be
difficult for the Series to enforce any rights it may have against the
registrar or issuer of the securities in the event of loss of share
registration. Although Russian companies with more than 1,000 shareholders are
required by law to employ an independent company to maintain share registers,
in practice, such companies have not always followed this law. Because of this
lack of independence of registrars, management of a Russian company may be
able to exert considerable influence over who can purchase and sell the
company's shares by illegally instructing the registrar to refuse to record
transactions on the share register. Furthermore, these practices may prevent
the Series from investing in the securities of certain Russian companies
deemed suitable by the Advisor and could cause a delay in the sale of Russian
securities by the Fund if the company deems a purchaser unsuitable, which may
expose the Fund to potential loss on its investment.
 
  In light of the risks described above, the Board of Trustees of the Series
has approved certain procedures concerning the Series' investments in Russian
securities. Among these procedures is a requirement that the Series will not
invest in the securities of a Russian company unless that issuer's registrar
has entered into a contract with the Series' sub-custodian containing certain
protective conditions including, among other things, the sub-custodian's right
to conduct regular share confirmations on behalf of the Series. This
requirement will likely have the effect of precluding investments in certain
Russian companies that the Series would otherwise make.
 
  For more detailed descriptions of these investment policies and techniques,
please refer to the Statement of Additional Information, which is available
without charge upon request by calling 1-800-448-2430

                              SEPTEMBER 15, 1998
 
  This Prospectus describes the BRINSON FUND-CLASS N SHARES of the investment
portfolios offered by The Brinson Funds (the "Trust"). The Trust is an open-
end management investment company advised by Brinson Partners, Inc. ("Brinson
Partners" or the "Advisor"), which currently offers eight distinct investment
portfolios: Global Fund, Global Equity Fund, Global Bond Fund, U.S. Balanced
Fund, U.S. Equity Fund, U.S. Large Capitalization Equity Fund, U.S. Bond Fund
and Non-U.S. Equity Fund (each a "Series" and collectively, the "Series").
Each Series offers three separate classes of shares-the Brinson Fund-Class N,
the Brinson Fund-Class I and the UBS Investment Funds class. The Brinson Fund-
Class N shares of the Series are referred to herein as the: Brinson Global
Fund, Brinson Global Equity Fund, Brinson Global Bond Fund, Brinson U.S.
Balanced Fund, Brinson U.S. Equity Fund, Brinson U.S. Large Capitalization
Equity Fund, Brinson U.S. Bond Fund and Brinson Non-U.S. Equity Fund (each a
"Fund" and collectively, the "Brinson Funds" or "Funds"). This Prospectus
pertains only to the Brinson Fund-Class N shares, which do not have a sales
load, but are subject to annual 12b-1 plan expenses. The Brinson Fund-Class I
shares, which are designed primarily for institutional investors, do not have
a sales load and are not subject to annual 12b-1 plan expenses. Further
information relating to the Brinson Fund-Class I shares may be obtained by

Funds class shares may be obtained by calling 1-800-794-7753.

/1/Pursuant to the terms of the Investment Advisory Agreements between the
   Trust on behalf of each Series and the Advisor, the Advisor is entitled to
   receive a monthly fee at the following annual rates for each of the Global
   Fund, Global Equity Fund, Global Bond Fund, U.S. Balanced Fund, U.S. Equity
   Fund, U.S. Large Capitalization Equity Fund, U.S. Bond Fund and Non-U.S.
   Equity Fund: 0.80%, 0.80%, 0.75%, 0.70%, 0.70%, 0.70%, 0.50% and 0.80%,
   respectively. Brinson Partners has agreed irrevocably to waive its fees and
   reimburse certain expenses so that total operating expenses, with the
   exception of 12b-1 expenses, of the Global Fund, Global Equity Fund, Global
   Bond Fund, U.S. Balanced Fund, U.S. Equity Fund, U.S. Large Capitalization
   Equity Fund, U.S. Bond Fund and Non-U.S. Equity Fund will never exceed
   1.10%, 1.00%, 0.90%, 0.80%, 0.80%, 0.80%, 0.60% and 1.00%, respectively.
   Absent these fee waivers and expense reimbursements, the total operating
   expenses for the Brinson Fund Class N shares of the Series for the fiscal
   year ended June 30, 1998 would have been 1.27% Global Equity Fund, 1.21%
   Global Bond Fund, 1.06% U.S. Balanced Fund, 1.84% U.S. Large Capitalization
   Equity Fund, and 1.09% U.S. Bond Fund. The fees and expenses for the U.S.
   Large Capitalization Equity Fund are based on the period from April 6, 1998
   (commencement of operations) to June 30, 1998.     
/2/For purposes of this Table, "12b-1 Expenses" is comprised of an asset-based
   sales charge of 0.25% of average daily net assets of each Series. See
   "Distribution Plan."
 
  Pursuant to rules of the National Association of Securities Dealers, Inc.
("NASD"), the aggregate initial sales charges, deferred sales charges and
asset-based sales charges on shares of the Funds may not exceed 6.25% of total
gross sales, subject to certain exclusions. This 6.25% limitation is imposed
on the Fund rather than on a per shareholder basis. Therefore, long-term
shareholders of the Brinson Funds may pay more than the economic equivalent of
the maximum front-end sales charges permitted by the NASD. This amount also
includes service fees.

EXAMPLE: Based on the level of expenses listed above after fee waivers and
reimbursements, the total expenses relating to an investment of $1,000 would
be as follows assuming a 5% annual return and redemption at the end of each
time period.

PRIOR PERFORMANCE OF ADVISOR
 
  The following table sets forth the Advisor's performance data relating to
the historical performance of funds contained within an institutional
collective investment trust ("CIT") (described below) managed by the Advisor.
Such CITs have investment objectives, policies, strategies and risks
substantially similar to those of the various Series of the Trust. The data is
provided to illustrate the past performance of the Trust. Advisor in managing
investment portfolios which are substantially similar to each applicable
Series of the Trust as measured against specified market indices. The
performance data of the Class N Shares of each Series of the Trust is also
included in the Table.
 
  The Advisor adopted the Performance Presentation Standards of the
Association for Investment Management and Research (AIMR Standards) as of
January 1, 1993. The CIT returns presented in this Prospectus are the
responsibility of the Advisor. They are presented in compliance with the
Performance Presentation Standards of the Association for Investment
Management and Research (AIMR--PPS(TM)). AIMR has not been involved with the
preparation or review of these returns.
 
  Investment results are time-weighted performance calculations representing
total return. Returns are calculated using geometric linking of monthly
returns. Each composite is a single entity composite, consisting of the assets
of each applicable fund of the Brinson Trust Company Collective Investment
Trust for Pension and Profit Sharing Trusts, or its predecessors, which may be
a single client. Clients must be an ERISA or governmental employee benefit
plan in order to qualify to invest in a CIT. Composites are valued monthly,
taking into account cash flows. All realized and unrealized capital gains and
losses, as well as all dividends and interest from investments and cash
balances, are included. Investment transactions are accounted for on a trade
date basis. Total returns for the CIT composites exclude the impact of
administrative expenses and the impact of any income taxes an investor might
have incurred as a result of taxable ordinary income and capital gains
realized by the CIT.
 
  The composite for each CIT is composed of all actual fee-paying,
discretionary client portfolios invested in the CIT. No alterations of
composites as presented here have occurred due to changes in personnel.
Accounts of all sizes invested in each CIT are included in composite
performance and no minimum account relationship size was set for inclusion in
the composites as the individual account size does not impact portfolio
management style. CIT's are not subject to certain expenses, investment
limitations, diversification requirements and restrictions to which the Series
are subject and which are imposed by the Investment Company Act of 1940 (the
"Act") and the Internal Revenue Code of 1986, as amended. Had such expenses,
limitations, requirements and restrictions been applicable to the CITs, the
performance results of the CIT composites could have been adversely affected.
The CITs performance presented does not represent the historical performance
of the Series and should not be interpreted as indicative of future
performance of the Series.

DESCRIPTION OF THE FUNDS
 
  The investment objective of each Series is fundamental and may not be changed
without the affirmative vote of the holders of a majority of the outstanding
voting securities of the Series, as defined in the Act. Unless otherwise stated
in this Prospectus or the Statement of Additional Information, each Series'
investment policies are not fundamental and may be changed without shareholder
approval. There can be no assurance that a Series will achieve its investment
objective.
 
  None of the Series intends to concentrate its investments in a particular
industry. None of the Series intends to issue senior securities as defined in
the Act, except that each Series may engage in borrowing activities as defined
in Appendix A and in the Statement of Additional Information. Each Series'
investment objective and its policies concerning portfolio lending, borrowing,
the issuance of senior securities and concentration are "fundamental," which
means that they may not be changed without the affirmative vote of the holders
of a majority of the Series' outstanding voting securities (as defined in the
Act).
 
INVESTMENT OBJECTIVES AND POLICIES
 
GLOBAL FUND
 
INVESTMENT OBJECTIVE
 
  The Global Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income. The Series will attempt
to control risk while seeking to achieve its investment objective. As a global
fund, at least 65% of the Series' total assets will be invested in securities
of issuers in at least three countries, one of which may be the United States.
The Series may utilize a wide range of equity, debt and money market securities
in domestic and foreign markets, and the Series may invest in other open-end
investment companies advised by Brinson Partners. The Series may enter into
repurchase agreements and reverse repurchase agreements, and engage in futures,
options and currency transactions for hedging and other permissible purposes,
as more fully described in "Investment Consideration and Risks" and Appendix A
in this Prospectus, and in the Statement of Additional Information.
 
  The Series is a diversified portfolio that seeks to achieve its objective by
pursuing active asset allocation strategies across global equity and fixed
income markets and active security selection within each market. These
decisions are undertaken relative to the GSMI Mutual Fund Index (the "Global
Benchmark"), which is compiled by Brinson Partners. The Global Benchmark
consists of eight distinct asset classes representing the primary wealth-
holding public securities markets. These asset classes are U.S. equities, non-
U.S. equities, emerging markets equities, U.S. bonds, non-U.S. bonds, emerging
markets bonds, high yield bonds and cash equivalents. Each asset class is
represented in the Global Benchmark by an index compiled by an independent data
provider. In order to compile the Global Benchmark, the Advisor determines
current relative market capitalizations in the world markets (U.S. equities,
non-U.S. equities, emerging markets equities, U.S. bonds, non-U.S. bonds,
emerging markets bonds, high yield bonds and cash) and then weights each
relevant index. Based on this
 
                                       8
<PAGE>
 
weighting, the Advisor determines the return of the relative indices, applies
the index weighting and then determines the return of the Global Benchmark.
From time to time, the Advisor may substitute an equivalent index within a
given asset class when it believes that such index more accurately reflects
the relevant global market.
 
  Although it may invest anywhere in the world, it is expected that the
Series' assets will be primarily invested in equity markets listed in the
Morgan Stanley Capital International ("MSCI") World Equity (Free) Index. The
Series will primarily invest in fixed income markets listed in the Salomon
World Government Bond Index. The Series may invest up to 10% of its net assets
in equity and debt securities of emerging market issuers, or securities with
respect to which the return is derived from the equity or debt securities of
issuers in emerging markets.
 
GLOBAL EQUITY FUND
 
INVESTMENT OBJECTIVE
 
  The Global Equity Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income. The Series will attempt
to control risk while seeking to achieve its investment objective. As a global
fund, at least 65% of the Series' total assets will be invested in equity
securities of issuers in at least three countries, one of which may be the
United States. The Series may utilize a wide range of equity securities that
are traded on both domestic and foreign stock exchanges or, in the case of
domestic stocks, in the over-the-counter market. The Series may enter into
repurchase agreements and reverse repurchase agreements, and engage in
futures, options and currency transactions for hedging and other permissible
purposes, as more fully described in "Investment Considerations and Risks" and
Appendix A in this Prospectus, and in the Statement of Additional Information.
 
  The Series is a diversified portfolio that seeks to achieve its objective by
pursuing an active asset allocation strategy across global equity markets,
active management of currency exposures and active security selection within
each market. The benchmark for the Series is the MSCI World Equity (Free)
Index (the "Global Equity Benchmark"). The Global Equity Benchmark is a market
driven broad based index which includes U.S. and non-U.S. equity markets in
terms of capitalization and performance. The Global Equity Benchmark is
designed to provide a representative total return for all major stock
exchanges located inside and outside the United States. Although it may invest
anywhere in the world, it is expected that the Series' assets will primarily
be invested in equity markets listed in the Global Equity Benchmark. From time
to time, the Advisor may substitute securities in an equivalent index when it
believes that such securities in the index more accurately reflect the
relevant global market.
 
GLOBAL BOND FUND
 
INVESTMENT OBJECTIVE
 
  The Global Bond Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income. The Series will attempt
to control risk while seeking to achieve its investment objective. As a global
fund, at least 65% of the Series' total assets will be invested in debt
securities with an initial maturity of more than one year of issuers in at
least three countries, one of which may be the United States. The Series seeks
to achieve this objective by investing primarily in debt securities that may
also provide the potential for capital appreciation. The Series may enter into
repurchase agreements and reverse repurchase agreements, and may engage in
futures, options and currency transactions for hedging and other permissible
purposes, as more fully described in "Investment Considerations and Risks" and
Appendix A in this Prospectus, and in the Statement of Additional Information.
 
  The Series is a non-diversified portfolio as described in "Investment
Considerations and Risks-Non-Diversified Status." The benchmark for the Series
is the Salomon World Government Bond Index (the "Global Bond Benchmark"). The
Global Bond Benchmark is a market driven index which measures the broad global
fixed
 
                                       9
<PAGE>
 
income markets invested in debt issues of U.S. and non-U.S. governments,
governmental entities and supranationals. Although it may invest anywhere in
the world, it is expected that the Series' assets will be primarily invested
in fixed income markets listed in the Global Bond Benchmark. From time to
time, the Advisor may substitute securities in an equivalent index when it
believes that such securities in the index more accurately reflect the
relevant global fixed income securities market.
 
U.S. BALANCED FUND
 
INVESTMENT OBJECTIVE
 
  The U.S. Balanced Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income. In seeking to achieve
its investment objective, the Series attempts to control risk. Under normal
circumstances, the Series will invest at least 25% of its net assets in fixed
income securities. The Series may utilize a wide range of equity, debt and
money market securities. The Series may also invest in equity securities,
including warrants, preferred stock and securities convertible into equity
securities. The Series may enter into repurchase agreements and reverse
repurchase agreements, and may engage in futures and options for hedging and
other permissible purposes, as more fully described in "Investment
Considerations and Risks" and Appendix A in this Prospectus, and in the
Statement of Additional Information. It is not the policy of the Series to
take unreasonable risks to obtain speculative or aggressively high returns.
 
  The Series is a diversified portfolio that seeks to achieve its objective by
pursuing active asset allocation strategies across U.S. equity and fixed
income markets and active security selection within each market. These
decisions are undertaken relative to the U.S. Balanced Mutual Fund Index (the
"U.S. Balanced Benchmark"), which is compiled by Brinson Partners. The U.S.
Balanced Benchmark represents a fixed composite of 65% Wilshire 5000 Index and
35% Salomon Brothers Broad Investment Grade (BIG) Bond Index. From time to
time, the Advisor may substitute an equivalent index within a given asset
class when the Advisor believes that such new index more accurately reflects
the relevant U.S. market.
 
U.S. EQUITY FUND
 
INVESTMENT OBJECTIVE
 
  The U.S. Equity Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income, while controlling risk.
Under normal circumstances, at least 65% of the Series' total assets will be
invested in equity securities of U.S. companies. The Series is a diversified
portfolio that seeks to achieve its objective by investing in a wide range of
equity securities of U.S. companies that are traded on major stock exchanges
as well as in the over-the-counter market. The Series may engage in futures
and options for hedging and other permissible purposes, as more fully
described in "Investment Considerations and Risks" and Appendix A in this
Prospectus, and in the Statement of Additional Information. The benchmark for
the Series is the Wilshire 5000 Index (the "U.S. Equity Benchmark"). The U.S.
Equity Benchmark is a broad weighted index which includes all U.S. common
stocks. The U.S. Equity Benchmark is designed to provide a representative
indication of the capitalization and return for the U.S. equity market.
 
U.S. LARGE CAPITALIZATION EQUITY FUND
 
INVESTMENT OBJECTIVE
 
  The U.S. Large Capitalization Equity Fund's investment objective is to
maximize total return, consisting of capital appreciation and current income,
while controlling risk. Under normal circumstances, at least 65% of the
Series' total assets will be invested in large capitalization equity
securities of U.S. companies. The Advisor defines
 
                                      10
<PAGE>
 
large capitalization companies as those with market capitalizations in the
upper 65% of the Wilshire 5000 Index at the time of the Series' investment.
Companies whose capitalization falls below this level after purchase continue
to be considered large capitalization companies. The Series is a non-
diversified portfolio as described in "Investment Considerations and Risk -
Non-Diversified Status." The Series seeks to achieve its objective by
investing in a wide range of equity securities of U.S. companies that are
traded on major stock exchanges as well as in the over-the-counter market. The
Series may engage in futures and options for hedging and other permissible
purposes, as more fully described in "Investment Considerations and Risks" and
Appendix A in this Prospectus, and in the Statement of Additional Information.
The benchmark for the Series is the Standard & Poor's 500 Stock Index (the
"U.S. Large Capitalization Equity Benchmark"). The U.S. Large Capitalization
Equity Benchmark is a broad weighted index which includes primarily U.S.
common stocks. The U.S. Large Capitalization Equity Benchmark is designed to
provide a representative indication of the capitalization and return for the
large capitalization U.S. equity market.
 
U.S. BOND FUND
 
INVESTMENT OBJECTIVE
 
  The U.S. Bond Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income, while controlling risk.
As a matter of fundamental policy, under normal circumstances, the Series
intends to invest at least 65% of its total assets in U.S. debt securities
with an initial maturity of more than one year. The Series is a diversified
portfolio that seeks to achieve its objective by investing primarily in fixed
income securities, which may also provide the potential for capital
appreciation. The Series may also engage in futures and options transactions
for hedging and other permissible purposes, as more fully described in
"Investment Considerations and Risks" and Appendix A in this Prospectus, and
in the Statement of Additional Information.
 
  The Series may invest in a broad range of fixed income securities, including
debt securities of the U.S. government, together with its agencies and
instrumentalities and the debt securities of U.S. corporations. A majority of
the fixed income securities in which the Series will invest will possess a
minimum rating of BBB- by Standard & Poor's Ratings Group ("S&P") or Baa3 by
Moody's Investors Services, Inc. ("Moody's") or, if unrated, will be
determined to be of comparable quality by Brinson Partners. Such securities
are considered to be investment grade. Other fixed income securities in which
the Series may invest include zero coupon securities, mortgage-backed
securities, asset-backed securities and when-issued securities. The Series may
invest a portion of its assets in short-term debt securities (including
repurchase and reverse repurchase agreements) of corporations, the U.S.
government or its agencies or instrumentalities, and banks and finance
companies.
 
  The benchmark for the Series is the Salomon Brothers Broad Investment Grade
(BIG) Bond Index (the "U.S. Bond Benchmark"). The U.S. Bond Benchmark is a
market driven broad based index which includes U.S. bonds with over one year
to maturity. From time to time, the Advisor may substitute securities in an
equivalent index when it believes that such securities in the index more
accurately reflect the relevant fixed income securities market.
 
NON-U.S. EQUITY FUND
 
INVESTMENT OBJECTIVE
 
  The Non-U.S. Equity Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income, by investing primarily
in the equity securities of non-U.S. issuers. Under
 
                                      11
<PAGE>
 
normal conditions, at least 65% of the Series' total assets will be invested
in equity securities of issuers in at least three countries other than the
United States. In seeking to achieve its investment objective while
controlling risk, the Series may invest in a wide range of equity securities,
including: American, European and Global Depositary Receipts, common and
preferred stock; debt securities convertible into or exchangeable for common
stock; and securities such as warrants or rights that are convertible into
common stock. The Series may engage in futures, options and currency
transactions for hedging and other permissible purposes, as more fully
described in "Investment Considerations and Risks" and Appendix A in this
Prospectus, and in the Statement of Additional Information.
 
  The Series is a diversified portfolio that seeks to achieve its objective by
investing primarily in the equity securities of non-U.S. issuers. The
benchmark for the Series is the MSCI Non-U.S. Equity (Free) Index (the "Non-
U.S. Equity Benchmark"). The Non-U.S. Equity Benchmark is a market driven
broad based index which includes non-U.S. equity markets in terms of
capitalization and performance. From time to time, the Advisor may substitute
securities in an equivalent index when it believes that such securities in the
index more accurately reflect the relevant international market. Although it
may invest anywhere in the world, it is expected that the Series' assets will
be primarily invested in the equity markets included in the MSCI Non-U.S.
Equity (Free) Index.
 
INVESTMENT CONSIDERATIONS AND RISKS
 
  The following provides information about the types of instruments in which
the Series may invest, strategies employed by Brinson Partners in its attempt
to attain each Series' investment objective and a summary of related risks.
Shareholders should understand that all investments involve risks and there
can be no guarantee against loss resulting from an investment in the Series,
nor can there be any assurance that the Series will be able to attain their
investment objectives. A complete list of the Series' investment restrictions
and more detailed information about the Series' investments are contained in
Appendix A in this Prospectus, and in the Statement of Additional Information.
 
  EQUITY SECURITIES (GLOBAL FUND, GLOBAL EQUITY FUND, U.S. BALANCED FUND, U.S.
EQUITY FUND, U.S. LARGE CAPITALIZATION EQUITY FUND AND NON-U.S. EQUITY FUND) -
 Equity securities fluctuate in value as a result of various factors, which
are often unrelated to the value of the issuer of the securities. These
fluctuations may be pronounced. The Global Fund may invest in small market
capitalization companies and in equity securities that are considered by the
Advisor to be in their post-venture capital stage. These securities may have
limited marketability, and therefore, may be more volatile. Fluctuations in
the value of the Series' equity investments will affect the value of their
shares and thus the Funds' total returns to investors.
 
  FIXED INCOME SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND) - All fixed income securities are subject to two types of
risks: credit risk and interest rate risk. The credit risk relates to the
ability of the issuer to meet interest or principal payments or both as they
come due. The interest rate risk refers to the fluctuations in the net asset
value of any portfolio of fixed income securities resulting from the inverse
relationship between the price and yield of fixed income securities; that is,
when the general level of interest rates rises, the prices of outstanding
fixed income securities decline, and when interest rates fall, prices rise.
 
  FOREIGN SECURITIES AND CURRENCY CONSIDERATIONS (GLOBAL FUND, GLOBAL EQUITY
FUND, GLOBAL BOND FUND AND NON-U.S. EQUITY FUND) - Investments in securities
of foreign issuers may involve greater risks than those of U.S. issuers. There
is generally less information available to the public about non-U.S. companies
and less government regulation and supervision of non-U.S. stock exchanges,
brokers and listed companies. Non-U.S.
 
                                      12
<PAGE>
 
companies are not subject to uniform global accounting, auditing and financial
reporting standards, practices and requirements. Securities of some non-U.S.
companies are less liquid and their prices more volatile than securities of
comparable U.S. companies. Securities trading practices abroad may offer less
protection to investors. Settlement of transactions in some non-U.S. markets
may be delayed or may be less frequent than in the United States, which could
affect the liquidity of the Series' portfolios. Additionally, in some non-U.S.
countries, there is the possibility of expropriation or confiscatory taxation,
limitations on the removal of securities, property or other assets of the
Series, political or social instability, or diplomatic developments which
could affect U.S. investments in those countries. The Series intend to
diversify broadly among countries, but reserve the right to invest a
substantial portion of their assets in one or more countries if economic and
business conditions warrant such investments. Brinson Partners will take these
factors into consideration in managing the Series' investments. Because the
Series will keep their books and records in U.S. dollars, the Series will be
required, for federal income tax purposes, to account for income and losses on
all transactions involving foreign currency under Section 988 of the Internal
Revenue Code of 1986, as amended, and the applicable U.S. Treasury
Regulations, so that generally any component of a gain or loss attributable to
currency fluctuations results in ordinary income or loss and not capital gain
or loss.
 
  The U.S. dollar market value of the Series' investments and of dividends and
interest earned by the Series may be significantly affected by changes in
currency exchange rates. Some currency prices may be volatile, and there is
the possibility of governmental controls on currency exchange or governmental
intervention in currency markets, which could adversely affect the Series.
Although the Series may attempt to manage currency exchange rate risks, there
is no assurance that the Series will do so at an appropriate time or that they
will be able to predict exchange rates accurately. For example, if the Series
increase their exposure to a currency and that currency's price subsequently
falls, such currency management may result in increased losses to the Series.
Similarly, if the Series decrease their exposure to a currency, and the
currency's price rises, the Series will lose the opportunity to participate in
the currency's appreciation. Each Series will manage currency exposures
relative to the normal currency allocation and will consider return and risk
of currency exposures relative to its respective Benchmark. In addition, if
the currency in which a security is denominated appreciates against the U.S.
dollar, the dollar value of the security will increase. Conversely, a decline
in the exchange rate of the currency would adversely affect the value of the
security expressed in dollars.
 
  On January 1, 1999, the European Monetary Union (the "EMU") plans to
introduce a new single currency, the Euro, which will replace the national
currencies of participating member nations. If the Series hold investments in
nations with currencies replaced by the Euro, the investment process,
including trading, foreign exchange, payments, settlements, cash accounts,
custody and accounting, will be impacted. Although it is not possible to
predict the impact of the Euro on the Series, the transition and the
elimination of currency risk among nations participating in the EMU may change
the economic environment and behavior of investors, particularly in European
markets.
 
  The adoption of the Euro does not reduce the currency risk presented by
fluctuations in value of the U.S. dollar to other currencies and, in fact,
currency exchange risk may be magnified. Also, increased market volatility may
result. Additional risks that may result include the fact that European
issuers in which the Series invest may face substantial conversion costs,
which may not be accurately anticipated and may impact issuer profitability
and creditworthiness.
   
  Brinson Partners has created an interdepartmental team to handle all Euro-
related changes to enable the Series to process transactions accurately and
completely with minimal disruption to business activities. While there can be
no assurance that the Series will not be adversely affected, Brinson Partners
and the Trust's service providers are taking steps that they believe are
reasonably designed to address the Euro issue.     
 
                                      13
<PAGE>
 
  There are additional risks inherent in investing in less developed countries
which are applicable to the Global Fund. Compared to the United States and
other developed countries, emerging market countries may have relatively
unstable governments, economies based on only a few industries, and securities
markets that trade only a small number of securities and employ settlement
procedures different from those used in the United States. Prices on these
exchanges tend to be volatile and, in the past, securities in these countries
have offered greater potential for gain (as well as loss) than securities of
companies located in developed countries. Further, investments by foreign
investors are subject to a variety of restrictions in many emerging countries.
 
  Emerging markets countries such as those in which the Global Fund may invest
have historically experienced and may continue to experience, high rates of
inflation, high interest rates, exchange rate fluctuations or currency
depreciation, large amounts of external debt, balance of payments and trade
difficulties and extreme poverty and unemployment. Additional factors which
may influence the ability or willingness to service debt include, but are not
limited to, a country's cash flow situation, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of its debt
service burden to the economy as a whole, its government's policy towards the
International Monetary Fund, the World Bank and other international agencies
and the political constraints to which a government debtor may be subject.
 
  FOREIGN CURRENCY TRANSACTIONS (GLOBAL FUND, GLOBAL EQUITY FUND, GLOBAL BOND
FUND AND NON-U.S. EQUITY FUND) - To manage exposure to currency fluctuations,
the Series may alter fixed income or money market exposures, enter into
forward currency exchange contracts, buy or sell options or futures relating
to foreign currencies and may purchase securities indexed to currency baskets.
The Series will also use these currency exchange techniques in the normal
course of business to hedge against adverse changes in exchange rates in
connection with purchases and sales of securities. Some of these strategies
may require the Series to set aside liquid assets in a segregated custodial
account to cover their obligations.
 
  FUTURES, OPTIONS AND OTHER DERIVATIVE INSTRUMENTS (ALL SERIES) - The Series
may attempt to reduce the overall level of investment risk of particular
securities and attempt to protect against adverse market movements by
investing in futures, options and other derivative instruments. A derivative
instrument is commonly defined as a financial instrument whose performance and
value are derived, at least in part, from another source, such as the
performance of an underlying asset, a specific security or an index of
securities. The derivative instruments in which the Series may invest include
the purchase and writing of options on securities (including index options)
and options on foreign currencies, investing in futures contracts for the
purchase or sale of instruments based on financial indices, including interest
rate indices or indices of U.S. or foreign government securities, equity or
fixed income securities ("futures contracts"), forward contracts and swaps and
swap-related products such as equity index swaps, interest rate swaps,
currency swaps, and related caps, collars and floors.
 
  The investment in futures, options, forward contracts, swaps and similar
strategies by the Series will depend on Brinson Partners' judgment as to the
potential risks and rewards of different types of strategies, and it should be
recognized that the use of these instruments exposes the Series to additional
investment risks and transaction costs. If the Advisor incorrectly analyzes
the market conditions or does not employ the appropriate strategy with respect
to these instruments, the Series could be left in a less favorable position.
For example, gains and losses on investments in futures depend on the
Advisor's ability to predict correctly the direction of security prices,
interest rates and other economic factors. Additional risks inherent in the
use of futures, options and forward contracts include: adverse movements in
the prices of securities or currencies being hedged; the possible absence of a
liquid secondary market for any particular instrument at any time; and the
possible need to defer closing out certain hedge positions to avoid adverse
tax consequences. Options and futures can be volatile instruments and may not
perform as expected. A Series could experience losses if the prices of its
options and futures positions are poorly correlated with its other
investments. If a hedge is applied at an inappropriate time or price
 
                                      14
<PAGE>
 
trends are judged incorrectly, options and futures strategies may lower a
Series' return (i.e., options and futures may fail as hedging techniques in
cases where the price movements of the securities underlying the options and
futures do not follow the price movements of the portfolio securities subject
to the hedge). Options and futures traded on foreign exchanges generally are
not regulated by U.S. authorities and may offer less liquidity and less
protection to a Series in the event of default by the other party to the
contract. The loss from investing in futures transactions is potentially
unlimited. A Series does not intend to purchase put and call options that are
traded on a national stock exchange in an amount exceeding 5% of its net
assets.
 
  Each Series may invest in derivatives for hedging purposes, to maintain
liquidity, or in anticipation of changes in the composition of its portfolio
holdings. No Series will engage in derivative investments purely for
speculative purposes. A Series will invest in one or more derivatives only to
the extent that the instrument under consideration is judged by the Advisor to
be consistent with the Series' overall investment objective and policies. In
making such judgment, the potential benefits and risks will be considered in
relation to the Series' other portfolio investments.
 
  Where not specified, investment limitations with respect to a Series'
derivative instruments will be consistent with that Series' existing
percentage limitations with respect to its overall investment policies and
restrictions. The risks and policies of various types of derivative
instruments permitted for the Series, including options, futures, forward
contracts and applicable interest rate swaps, are described in greater detail
in Appendix A in this Prospectus, and in the Statement of Additional
Information.
 
  NON-DIVERSIFIED STATUS (GLOBAL BOND FUND AND U.S. LARGE CAPITALIZATION
EQUITY FUND ONLY) - Each Series is classified as a "non-diversified"
investment company under the Act, which means that the proportion of the
Series' assets that may be invested in the securities of a single issuer is
not limited by the Act. Since each Series may invest a larger portion of its
assets in the securities of a single issuer than investment companies that are
classified as diversified funds under the Act, an investment in the Global
Bond Fund or in the U.S. Large Capitalization Equity Fund may be subject to
greater fluctuations in value than an investment in a diversified fund.
 
MANAGEMENT OF THE TRUST
 
THE BOARD OF TRUSTEES
 
  The Trust is a Delaware business trust. Under Delaware law, the Board of
Trustees has overall responsibility for managing the business and affairs of
the Trust. The Trustees elect the officers of the Trust, who are responsible
for administering the day-to-day operations of the Series.
 
THE ADVISOR
   
  Brinson Partners, a Delaware corporation, is an investment management firm,
managing as of June 30, 1998, over $286 billion, primarily for pension and
profit sharing institutional accounts. Brinson Partners and its predecessor

and global investment assets since 1982. Brinson Partners has offices in
Bahrain, Basel, Frankfurt, Geneva, Hong Kong, London, Melbourne, New York,
Paris, Rio de Janeiro, Singapore, Sydney, Tokyo and Zurich, in addition to its
principal office at 209 South LaSalle Street, Chicago, IL 60604-1295. Brinson
Partners is a part of the UBS Brinson Division of UBS AG. UBS AG, with
headquarters in Basel, Switzerland, is an internationally diversified
organization with operations in many aspects of the financial services
industry. UBS AG was formed by the merger of Union Bank of Switzerland and
Swiss Bank Corporation in June 1998.     
 
                                      15

  Brinson Partners also serves as the investment advisor to nine other
investment companies: Brinson Relationship Funds, which includes seventeen
investment portfolios (series); The Enterprise Group of Funds, Inc. -
International Growth Portfolio; Enterprise Accumulation Trust - International
Growth Portfolio; Fort Dearborn Income Securities, Inc.; The Hirtle Callaghan
International Trust - The International Equity Portfolio; John Hancock
Variable Annuity Series Trust I - International Balanced Portfolio; Managed
Accounts Services Portfolio Trust -  Pace Large Company Value Equity
Investments; AON Funds - International Equity Fund; and The Republic Funds -
Republic Equity Fund.
 
  Pursuant to its investment advisory agreements (the "Agreements") with the
Trust on behalf of each Series, Brinson Partners is entitled to receive a
monthly fee at various annual percentage rates of the Series' average daily
net assets, as described below, for providing investment advisory services.
Brinson Partners is responsible for paying its own expenses. Pursuant to the
Agreements, Brinson Partners is authorized, at its own expense, to obtain
statistical and other factual information and advice regarding economic
factors and trends from its foreign subsidiaries, but it does not generally
receive advice or recommendations regarding the purchase or sale of securities
from such subsidiaries.
 
  For providing investment advisory services during the fiscal year ended June
30, 1998, Brinson Partners was entitled to receive, under the Agreements, a
monthly fee at an annual rate as follows of the average daily net assets of
the Funds:
 
<TABLE>
      <S>                                                                  <C>
      Global Fund......................................................... 0.80%
      Global Equity Fund.................................................. 0.80
      Global Bond Fund.................................................... 0.75

      U.S. Bond Fund...................................................... 0.50
      Non-U.S. Equity Fund................................................ 0.80
</TABLE>
 
  The fee payable to Brinson Partners by the Global, Global Equity and Non-
U.S. Equity Funds is higher than the advisory fees paid by most other mutual
funds, but is comparable to those of other mutual funds with similar
investment objectives. The Advisor, however, has irrevocably agreed to waive
its fees and reimburse certain expenses so that the total operating expenses,
with the exception of 12b-1 expenses, of the Brinson Global Fund-Class N,
Brinson Global Equity Fund-Class N, Brinson Global Bond Fund-Class N, Brinson
U.S. Balanced Fund-Class N, Brinson U.S. Equity Fund-Class N, Brinson U.S.
Large Capitalization Equity Fund-Class N, Brinson U.S. Bond Fund-Class N and
Brinson Non-U.S. Equity Fund-Class N will never exceed 1.10%, 1.00%, 0.90%,
0.80%, 0.80%, 0.80%, 0.60% and 1.00%, respectively.
 
PORTFOLIO MANAGEMENT
 
  Investment decisions for the Series are made by an investment management
team at Brinson Partners. No member of the investment management team is
primarily responsible for making recommendations for portfolio purchases.

ADMINISTRATION OF THE TRUST
 
THE UNDERWRITER
 
  Funds Distributor, Inc. ("FDI"), 60 State Street, Suite 1300, Boston, MA
02109, was engaged pursuant to an agreement dated February 5, 1997, for the
limited purpose of acting as underwriter to facilitate the filing of notices
regarding sale of the shares of the Trust under state securities laws and to
assist in the sale of shares. The fee for such service is borne by the
Advisor.
 
THE ADMINISTRATOR
 
ADMINISTRATIVE, ACCOUNTING, TRANSFER AGENCY AND CUSTODIAN SERVICES
 
  The Trust, on behalf of each Series, has entered into a Multiple Services
Agreement (the "Services Agreement") with Morgan Stanley Trust Company
("MSTC"), One Pierrepont Plaza, Brooklyn, New York 11201, pursuant to which
MSTC is required to provide general administrative, accounting, portfolio
valuation, transfer agency and custodian services to the Series, including the
coordination and monitoring of any third party service providers.
 
  MSTC provides custodian services for the securities and cash of the Series.
The custody fee schedule is based primarily on the net amount of assets held
during the period for which payment is being made.
 
  As authorized under the Services Agreement, MSTC has entered into a Mutual
Funds Service Agreement (the "CGFSC Agreement") with Chase Global Funds
Services Company ("CGFSC"), a corporate affiliate of The Chase Manhattan Bank,
under which CGFSC provides administrative, accounting, portfolio valuation and
transfer agency services to the Series. CGFSC's business address is 73 Tremont
Street, Boston, Massachusetts 02108-3913. Subject to the supervision of the
Board of Trustees of the Trust, MSTC supervises and monitors such services
provided by CGFSC.
 
  Pursuant to the CGFSC Agreement, CGFSC provides:
 
    (1) administrative services, including providing the necessary office
  space, equipment and personnel to perform administrative and clerical
  services; preparing, filing and distributing proxy materials, periodic
  reports to investors, registration statements and other documents; and
  responding to investor inquiries;
 
    (2) accounting and portfolio valuation services, including the daily
  calculation of each Fund's net asset value and the preparation of certain
  financial statements; and
 
    (3) transfer agency services, including the maintenance of each
  investor's account records, responding to investors' inquiries concerning
  accounts, processing purchases and redemptions of each Fund's shares,
  acting as dividend and distribution disbursing agent and performing other
  service functions. Shareholder inquiries should be made to the transfer
  agent at 1-800-448-2430.
 
  Also as authorized under the Services Agreement, MSTC has entered into a
sub-administration agreement (the "FDI Agreement") with FDI under which FDI
provides administrative assistance to the Series with respect to (i)
regulatory matters, including regulatory developments and examinations, (ii)
all aspects of the Series' day-to-day operations, (iii) office facilities,
clerical and administrative services, and (iv) maintenance of books and
records.
 
 
                                      17
<PAGE>
 
  For its administrative, accounting, transfer agency and custodian services,
MSTC receives the following as compensation from the Trust on an annual basis:
0.0025% of the average daily U.S. assets of the Trust; 0.0525% of the average
daily non-U.S. assets of the Trust; 0.3250% of the average daily emerging
markets equity assets of the Trust; and 0.019% of the average daily emerging
markets debt assets of the Trust. MSTC receives an additional fee of 0.075% of
the average daily net assets of the Trust for administrative duties, the
latter subject to the expense limitation applicable to the Trust. No fee
(asset based or otherwise) is charged on any investments made by any fund into
any other fund sponsored or managed by the Advisor and assets of a fund that
are invested in another investment company or series thereof sponsored or
managed by the Advisor will not be counted in determining the 0.075%
administrative duties fee or the applicability of the expense limitation on
such fee. The foregoing fees include all out-of-pocket expenses or transaction
charges incurred by MSTC and any third party service provider in providing
such services. Pursuant to the CGFSC Agreement and the FDI Agreement, MSTC
pays CGFSC and FDI, respectively, for the services that CGFSC and FDI provide
to MSTC in fulfilling MSTC's obligations under the Services Agreement.
 
INDEPENDENT AUDITORS
 
  Ernst & Young LLP, Chicago, Illinois, are the independent auditors of the
Trust.
 
PURCHASE OF SHARES
 
  Shares of the Funds may be purchased directly from the Trust at the net
asset value next determined after receipt of the order in proper form by the
transfer agent. There is no sales load in connection with the purchase of Fund
shares. The Trust reserves the right to reject any purchase order and to
suspend the offering of shares of the Brinson Fund-Class N shares or any
Series. The Funds will not accept a check endorsed over by a third-party. The
minimum initial investment for Fund shares is $1,000,000. The minimum initial
investment for Individual Retirement Accounts ("IRAs") is $2,000. The Trust
reserves the right to vary the initial investment minimum and impose minimums
for additional investments in any of the Funds at any time. In addition,
Brinson Partners may waive the minimum initial investment requirement for any
investor.
 
  The Brinson Funds may be purchased through broker-dealers having sales
agreements with FDI, or through financial institutions having agency
agreements with FDI. There is no sales load or charge in connection with the
purchase of shares. The Brinson Fund-Class N shares, however, are subject to
annual 12b-1 plan expenses of 0.25% of the Funds' average daily net assets of
such shares.
   
  The Brinson Fund-Class N shares may also be marketed directly through the
offices of UBS AG. Through its branches and subsidiaries, UBS AG conducts
securities research, provides investment advisory services and manages mutual
funds in major cities throughout the world, including Amsterdam, Basel,
Frankfurt, Geneva, Hong Kong, Houston, London, Los Angeles, Luxembourg, Miami,
Monte Carlo, New York, Paris, San Francisco, Singapore, Sydney, Tokyo, Toronto
and Zurich.     
 
  Purchase orders for shares of the Funds which are received by the transfer
agent in proper form prior to the close of regular trading hours (currently
4:00 p.m. Eastern time) on the New York Stock Exchange (the "NYSE") on any day
that the Funds' net asset values per share are calculated, are priced
according to the net asset value determined on that day. Purchase orders for
shares of the Funds received after the close of the NYSE on a particular day
are priced as of the time the net asset value per share is next determined.
The Funds reserve the right to change the time at which purchases are priced
if the NYSE closes at a time other than 4:00 p.m. Eastern time or if an
emergency exists.
 
                                      18

  Under certain circumstances, the Trust has entered into one or more
agreements (each, a "Sales Agreement") with brokers, dealers or financial
institutions (each, an "Authorized Dealer") under which the Authorized Dealer
may directly, or through intermediaries that the Authorized Dealer is
authorized to designate under the Sales Agreement (each, a "Sub-designee"),
accept purchase and redemption orders that are in "good form" on behalf of the
Funds. A Fund will be deemed to have received a purchase order when the
Authorized Dealer or Sub-designee accepts the purchase order and such order
will be priced at the Fund's net asset value next computed after such order is
accepted by the Authorized Dealer or Sub-designee.
 
  The Trust may accept telephone orders for Fund shares from broker-dealers or
service organizations which have been previously approved by the Trust. It is
the responsibility of such broker-dealers or service organizations to promptly
forward purchase orders and payments for the same to the Fund. Shares of the
Funds may be purchased through broker-dealers, banks and bank trust
departments which may charge the investor a transaction fee or other fee for
their services at the time of purchase. Such fees would not otherwise be
charged if the shares were purchased directly from the Trust.
 
  Brinson Partners, or its affiliates, from its own resources, may compensate
broker-dealers or other financial intermediaries ("Service Providers") for
marketing, shareholder servicing, recordkeeping and/or other services
performed with respect to a Fund's Class N shares. Payments made for any of
these purposes may be made from its revenues, its profits or any other sources
available to it. When such service arrangements are in effect, they are made
generally available to all qualified Service Providers.

REDEMPTION OF SHARES
 
  Shares of the Funds may be redeemed without charge on any business day that
the NYSE is open. Redemptions will be effected at the net asset value per
share next determined after the receipt by the transfer agent of a redemption
request meeting the requirements described below. The Trust normally sends
redemption proceeds on the next business day but, in any event, redemption
proceeds are sent within five business days of receipt of a redemption request
in proper form. Payment also may be made by wire directly to any bank
previously designated by the shareholder in an Account Application. Please
note that the shareholder's bank may impose a fee for wire service. The Trust
will honor redemption requests of shareholders who recently purchased shares
by check, but will not mail the proceeds until it is reasonably satisfied that
the purchase check has cleared, which may take up to fifteen days from the
purchase date.
 
  Except as noted below, redemption requests received in proper form by the
transfer agent prior to the close of regular trading hours on the NYSE on any
business day that the Funds' net asset values per share are calculated are
effected that day. The Funds reserve the right to change the time at which
redemptions are priced if the NYSE closes at a time other than 4:00 p.m.
Eastern time or if an emergency exists. Redemption requests received in proper
form by the transfer agent after the close of the NYSE are effected as of the
time the net asset value per share is next determined. No redemption will be
processed until the transfer agent has received a completed application with
respect to the account.
 
  Shares of the Funds may be redeemed through certain broker-dealers, banks
and bank trust departments who may charge the investor a transaction fee or
other fee for their services at the time of redemption. Such fees would not
otherwise be charged if the shares were redeemed directly from the Trust.
 
  Under the Sales Agreement, the Authorized Dealer or Sub-designee is
authorized to accept redemption orders on behalf of the Funds. A Fund will be
deemed to have received a redemption order when the Authorized Dealer or Sub-
designee accepts the redemption order and such order will be priced at the
Fund's net asset value next computed after such order is accepted by the
Authorized Dealer or Sub-designee.
 
  The Trust will satisfy redemption requests in cash to the fullest extent
feasible, so long as such payments would not, in the opinion of Brinson
Partners or the Board of Trustees, result in the necessity of a Series selling
assets under disadvantageous conditions and to the detriment of the remaining
shareholders of the Series. Pursuant to the Trust's Agreement and Declaration
of Trust, payment for shares redeemed may be made either in cash or in-kind,
or partly in cash and partly in-kind. However, the Trust has elected, pursuant
to Rule 18f-1 under the Act, to redeem its shares solely in cash up to the
lesser of $250,000 or 1% of the net asset value of a Series, during any 90-day
period for any one shareholder. Payments in excess of this limit will also be
made wholly in cash unless the Board of Trustees believes that economic
conditions exist which would make such a practice detrimental to the best
interests of the Series. Any portfolio securities paid or distributed in-kind
would

                                      21
<PAGE>
 
be valued as described under "Net Asset Value." In the event that an in-kind
distribution is made, a shareholder may incur additional expenses, such as the
payment of brokerage commissions, on the sale or other disposition of the
securities received from a Series. In-kind payments need not constitute a
cross-section of a Series' portfolio. Where a shareholder has requested
redemption of all or a part of the shareholder's investment and where a Series
computes such redemption in-kind, the Series will not recognize gain or loss
for federal tax purposes on the securities used to compute the redemption, but
the shareholder will recognize gain or loss equal to the difference between
the fair market value of the securities received and the shareholder's basis
in the Fund shares redeemed.
 
SHARES MAY BE REDEEMED IN ONE OF THE FOLLOWING WAYS:

NOTE: The Trust reserves the right to refuse a wire or telephone redemption if
     it is believed advisable to do so. Procedures for redeeming shares of the
     Brinson Funds by wire or telephone may be modified or terminated at any
     time by the Trust.
 
TELEPHONE TRANSACTIONS:
 
  Shareholders who wish to initiate purchase, exchange or redemption
transactions by telephone must elect the option, as described above. With
respect to such telephone transactions, the Funds will ensure that
 
                                      22
<PAGE>
 
reasonable procedures are used to confirm that instructions communicated by
telephone are genuine (including verification of the shareholder's social
security number or mother's maiden name) and, if they do not, the Funds or the
transfer agent may be liable for any losses due to unauthorized or fraudulent
transactions. Written confirmation will be provided for all purchase, exchange
and redemption transactions initiated by telephone.
 
EXCHANGE OF SHARES:
 
  Fund shares may be exchanged for Brinson Fund-Class N shares of any other
Series within the Trust. Exchanges will not be permitted between the Brinson
Fund-Class N shares and either the UBS Investment Funds class of shares or the
Brinson Fund-Class I shares of a Series of the Trust.
 
  Fund shares may be exchanged by written request or by telephone if the
shareholder has previously signed a telephone authorization on the Account
Application. The telephone exchange may be difficult to implement during times
of drastic economic or market changes. The Trust reserves the right to
restrict the frequency of, or otherwise modify, condition, terminate or impose
charges upon the exchange and/or telephone transfer privileges upon 60 days'
prior written notice to shareholders.
 
  Exchanges will be made on the basis of the relative net asset value per
share of the Brinson Fund-Class N shares of the Fund from which, and the Fund
into which, the exchange is made. Exchanges may be made only for shares of a
Series and class then offering its shares for sale in your state of residence
and are subject to the minimum initial investment requirement. For federal
income tax purposes, an exchange of shares would be treated as if the
shareholder had redeemed shares of one Series and reinvested in shares of
another Series. Gains or losses on the shares exchanged are realized by the
shareholder at the time of the exchange. Any shareholder wishing to make an
exchange should first obtain and review a prospectus of the other Series.
Requests for telephone exchanges must be received by the transfer agent by the
close of regular trading hours (currently 4:00 p.m. Eastern time) on the NYSE
on any day that the NYSE is open for regular trading. The Funds reserve the
right to change the time at which exchanges are priced if the NYSE closes at a
time other than 4:00 p.m. Eastern time or if an emergency exists.
 
TRANSFER OF SECURITIES:
 
  At the discretion of the Trust, investors may be permitted to purchase Fund
shares by transferring securities to a Series that meet the Series' investment
objective and policies. Securities transferred to a Series will be valued in
accordance with the same procedures used to determine the Fund's net asset
value at the time of the next determination of net asset value after such
acceptance. Shares issued by a Series in exchange for securities will be
issued at net asset value per share of the Fund determined as of the same
time. All dividends, interest, subscription, or other rights pertaining to
such securities shall become the property of the Series and must be delivered
to the Series by the investor upon receipt from the issuer. Investors who are
permitted to transfer such securities will be required to recognize a gain or
loss on such transfer and pay tax thereon, if applicable, measured by the
difference between the fair market value of the securities and the investors'
basis therein. Securities will not be accepted in exchange for shares of a
Fund unless: (1) such securities are, at the time of the exchange, eligible to
be included in the Series' portfolio and current market quotations are readily
available for such securities; (2) the investor represents and warrants that
all securities offered to be exchanged are not subject to any restrictions
upon their sale by the Series under the Securities Act of 1933, as amended, or
under the laws of the country in which the principal market for such
securities exists, or otherwise; and (3) the value of any such security
(except U.S. government securities) being exchanged, together with other
securities of the same issuer owned by the Series, will not exceed 5% of the
Series' net assets immediately after the transaction.

NET ASSET VALUE
 
  The net asset value per share for each class of shares of the Series is
computed by adding, with respect to each class of shares, the value of a
Series' investments, cash and other assets attributable to that class,
deducting liabilities of the class and dividing the result by the number of
shares of that class outstanding. The public offering price of the shares of
each classes' shares, all of which are sold on a continuous basis, is the net
asset value of that class. The valuation of assets for determining the net
asset value may be summarized as follows:
 
    Securities traded on securities exchanges are valued at the last
  available sale price. Securities that are not traded on a particular day or
  on an exchange are valued at either (a) the bid price or (b) a valuation
  within the range considered best to represent value in the circumstances.
  Price information on listed securities is generally taken from the closing
  price on the exchange where the security is primarily traded. Valuations of
  equity securities may be obtained from a pricing service and/or broker-
  dealers when such prices are believed to reflect fair value of such
  securities. Use of a pricing service and/or broker-dealers has been
  approved by the Board of Trustees. Futures contracts are valued at their
  daily quoted settlement price on the exchange on which they are traded.
  Forward foreign currency contracts are valued daily using the mean between
  the bid and asked forward points added to the current exchange rate and an
  unrealized gain or loss is recorded. The Series realizes a gain or loss
  upon settlement of the contracts. For valuation purposes, foreign
  securities initially expressed in foreign currency values will be converted
  into U.S. dollar values using WM/Reuters closing spot rates as of 4:00 p.m.
  London time.
 
    Securities with a remaining maturity of 60 days or less are valued at
  amortized cost, which approximates market value. Fixed income securities
  having a remaining maturity of over 60 days are valued at market price.
  Debt securities are valued on the basis of prices provided by a pricing
  service, or at the bid price where readily available, as long as the bid
  price, in the opinion of the Advisor, continues to reflect the value of the
  security. Redeemable securities issued by open-end investment companies are
  valued using their respective net asset values for purchase orders placed
  at the close of the NYSE. Securities (including over-the-counter options)
  for which market quotations are not readily available and other assets are
  valued at their fair value as determined in good faith by or under the
  direction of the Trustees.
 
  Net asset value is determined on each day that the NYSE is open, as of the
close of business of the regular session of the NYSE (currently 4:00 p.m.
Eastern time). Investments and requests to exchange or redeem shares received
by the Series in proper form before such close of business are effective, and
will receive the price determined, on that day. Investment, exchange and
redemption requests received after such close of business are effective, and
will receive the share price determined, on the next business day. The Funds
reserve the right to change the time at which purchases, redemptions and
exchanges are priced if the NYSE closes at a time other than 4:00 p.m. Eastern
time or if an emergency exists.
 
  Because of time zone differences, foreign exchanges and securities markets
will usually be closed prior to the time of the closing of the NYSE and values
of foreign futures and options and foreign securities will be determined as of
the earlier closing of such exchanges and securities markets. However, events
affecting the values of such foreign securities may occasionally occur between
the earlier closings of such exchanges and securities markets and the closing
of the NYSE which will not be reflected in the computation of the net asset
value of a class of a Series. If an event materially affecting the value of
such foreign securities occurs during such period, then such securities will
be valued at fair value as determined in good faith by or under the direction
of the Board of Trustees. Where a foreign securities market remains open at
the time that a Series values its portfolio securities, or closing prices of
securities from that market may not be retrieved because of local time
differences or other difficulties in obtaining such prices at that time, last
sale prices in such market at a point in time most practicable to timely
valuation of the Series may be used.
 
 
                                      24
<PAGE>
 
  The Series' portfolio securities from time to time may be listed primarily
on foreign exchanges which trade on days when the NYSE is closed (such as
Saturday). As a result, the net asset value of a class of a Fund may be
significantly affected by such trading on days when shareholders have no
access to the Fund.
 
  All of the Series' classes of shares will bear pro rata all of the expenses
of that Series common to all classes. The net asset value of all outstanding
shares of each class of the Series will be computed on a pro rata basis for
each outstanding share based on the proportionate participation in the Series
represented by the value of shares of that class. All income earned and
expenses incurred by the Series will be borne on a pro rata basis by each
outstanding share of a class, based on each class' proportionate participation
in the Series represented by the value of shares of such class, except that
the Brinson Fund-Class N and UBS Investment Funds class of shares will bear
12b-1 expenses payable under their respective 12b-1 plans.
 
  Due to the specific distribution expenses and other costs that will be
allocable to each class, the dividends paid to each class, and related
performance, of the Series may vary. The per share net asset value of the
Brinson Fund-Class N shares and the UBS Investment Funds class of shares will
generally be lower than that of the Brinson Fund-Class I shares of a Series
because of the higher expenses borne by the UBS Investment Funds class of
shares and the Brinson Fund-Class N shares. It is expected, however, that the
net asset value per share of the two classes will tend to converge immediately
after the payment of dividends, which will differ by approximately the amount
of the service and distribution expenses differential among the classes.
 
DISTRIBUTION PLAN
 
  The Board of Trustees of the Trust has adopted a distribution plan (the
"Plan") pursuant to Rule 12b-1 under the Act for the Brinson Fund-Class N
shares. The Plan permits each Series to reimburse FDI, Brinson Partners and
others from the assets of the Brinson Fund-Class N shares a quarterly fee for
services and expenses incurred in distributing and promoting sales of the
Brinson Fund-Class N shares. These expenses include, but are not limited to,
preparing and distributing advertisements and sales literature, printing
prospectuses and reports used for sales purposes, and paying distribution and
maintenance fees to brokers, dealers and others in accordance with a selling
agreement with the Trust on behalf of the Brinson Fund-Class N shares or FDI.
In addition, each Series may make payments directly to FDI for payment to
dealers or others, or directly to others, such as banks, who assist in the
distribution of the Brinson Fund-Class N shares or provide services with
respect to the Brinson Fund-Class N shares.
 
  UBS AG, or one of its affiliates, pursuant to a selected dealer agreement,
may provide additional compensation to securities dealers from its own
resources in connection with sales of the Brinson Fund-Class N shares of the
Series.
 
  The aggregate distribution fees paid by the Series from the assets of the
respective Brinson Fund-Class N shares to FDI and others under the Plan may
not exceed 0.25% of a Fund's average daily net assets in any year.
 
  The Plan applies only to the Brinson Fund-Class N shares of each Series.
Shares of other classes are not included in calculating the Plan's fees and
the Plan is not used to assist in the distribution and marketing of each
Series' UBS Investment Funds class of shares or Brinson Fund-Class I shares.
All payments made by the Brinson Fund-Class N shares of a Series pursuant to
the Plan shall be made for the purpose of selling shares issued by the Brinson
Fund-Class N of the Series. Distribution expenses which are attributable to a
particular class of a Series will be charged against the assets of that class
of that Series. Distribution expenses which are attributable to more than one
class or Series will be allocated among the classes or Series, in proportion
to their relative net assets.
 
 
                                      25
<PAGE>
 
  The quarterly fees paid to FDI under the Plan are subject to the review and
approval by the Trust's Trustees who are not "interested persons" of the
Advisor or FDI (as defined in the Act) and who may reduce the fees or
terminate the Plan at any time.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
 
DIVIDENDS
 
  The Series will distribute their net investment income semi-annually in June
and December. The Series will distribute annually in December substantially
all of their net long-term capital gains and any undistributed net short-term
capital gains realized during the one year period commencing November 1 (or
date of the creation of the Series, if later) and ending October 31, and, at
the same time, will distribute all of their net investment income earned
through the end of December and not previously distributed as ordinary (not
capital) income.
 
  Dividends and other distributions paid by a Series with respect to its
Brinson Fund-Class N, Brinson Fund-Class I and UBS Investment Funds class of
shares are calculated in the same manner and at the same time. The per share
amount of any income dividends will generally differ among the classes only to
the extent that the Brinson Fund-Class N and UBS Investment Funds class of
shares are subject to separate 12b-1 fees. The per share dividends on UBS
Investment Funds class of shares and Brinson Fund-Class N shares will be lower
than the per share dividends on the Brinson Fund-Class I shares of each Series
as a result of the distribution and service fees applicable with respect to
the UBS Investment Funds class of shares and Brinson Fund-Class N shares.
 
  Income dividends and capital gain distributions are reinvested automatically
in additional Fund shares of the same class of Series at net asset value,
unless the shareholder has notified the transfer agent, in writing, of the
shareholder's election to receive them in cash. Distribution options may be
changed at any time by requesting a change in writing. Any check in payment of
dividends or other distributions which cannot be delivered by the Post Office
or which remains uncashed for a period of more than one year may be reinvested
in the shareholder's account at the then current net asset value and the
dividend option may be changed from cash to reinvest. Dividends are reinvested
on the ex dividend date (the "ex date") at the net asset value determined at
the close of business on that date. Please note that shares purchased shortly
before the record date for a dividend or distribution may have the effect of
returning capital although such dividends and distributions are subject to
taxes.
 
TAXES
 
  Each Series has qualified, and intends to continue to qualify, for taxation
as a "regulated investment company" under the Internal Revenue Code of 1986,
as amended ("the Code"). Such qualification relieves a Series of liability for
federal income taxes to the extent the Series' earnings are distributed in
accordance with the Code. Each Series is treated as a separate corporate
entity for federal tax purposes.
 
  Distributions of any net investment income and of any net realized short-
term capital gains are taxable to shareholders as ordinary income. All
distributions may be subject to state and local taxes.
 
  Distributions of net capital gain (the excess of net long-term capital gain
over net short-term capital loss) are taxable to shareholders as long-term
capital gain regardless of how long a shareholder may have held shares of a
Series. The tax treatment of distributions of ordinary income or capital gains
will be the same whether the shareholder reinvests the distributions or elects
to receive them in cash. A distribution will be treated as paid on
 
                                      26
<PAGE>
 
December 31 of the current calendar year if it is declared in October,
November or December with a record date in such a month and paid during
January of the following calendar year. Such distributions will be taxable to
shareholders in the calendar year in which the distributions are declared,
rather than the calendar year in which the distributions are received.
 
  Shareholders will be advised annually of the source and tax status of all
distributions for federal income tax purposes. Further information regarding
the tax consequences of investing in the Series is included in the Statement
of Additional Information. The above discussion is intended for general
information only. Investors should consult their own tax advisors for more
specific information on the tax consequences of particular types of
distributions.
 
  Redemptions of Series shares, and the exchange of shares between two Series
of the Trust, are taxable events and, accordingly, shareholders may realize
capital gains or losses on these transactions.
 
  Shareholders may be subject to back-up withholding on reportable dividend
and redemption payments ("back-up withholding") if a certified taxpayer
identification number is not on file with the Series, or if, to the Series'
knowledge, an incorrect number has been furnished, or if the Series has been
notified by the Internal Revenue Service that an account is subject to back-up
withholding. An individual's taxpayer identification number is the
individual's social security number.
 
  If more than 50% of a Series' total assets at the close of its taxable year
consists of stock or securities in foreign corporations, the Series may elect
to "pass-through" to shareholders for foreign tax credit purposes the amount
of foreign income taxes paid by the Series with respect to its direct holdings
of securities in foreign corporations. A Series will make such an election
only if it deems such election to be in the best interests of its
shareholders. If this election is made, shareholders of the Series will be
required to include in their gross incomes their pro rata share of foreign
taxes paid by the Series. However, shareholders will be able to treat their
pro rata share of foreign taxes as either a deduction (itemized deduction in
the case of individuals) or a foreign tax credit (but not both) against U.S.
income taxes on their tax returns. A Series which makes investments in the
securities of foreign corporations may make investments in foreign companies
that are "passive foreign investment companies" ("PFICs"). These investments
in PFICs may cause a Series to pay income taxes and interest charges. If
possible, the Series will not invest in PFICs or will adopt other strategies
to avoid these taxes and charges.
 
GENERAL INFORMATION
 
ORGANIZATION
 
  The Brinson Funds is a Delaware business trust organized pursuant to an
Agreement and Declaration of Trust, dated December 1, 1993. The Trust was
originally organized as a Maryland corporation on April 14, 1992. On December
1, 1993, the Trust reorganized as a Delaware business trust through a merger
of the Maryland corporation into the Trust. The Trust is registered under the
Act as an open-end management investment company, commonly known as a mutual
fund and consists of eight different Series. The Trustees of the Trust may
establish additional series or classes of shares without the approval of
shareholders. All of the Series, except the Global Bond Fund and the U.S.
Large Capitalization Equity Fund, are diversified portfolios. The assets of
each Series belong only to that Series, and the liabilities of each Series are
borne solely by that Series and no other.
 
DESCRIPTION OF SHARES
 
  Each Series is authorized to issue an unlimited number of shares of
beneficial interest with a $0.001 par value per share. The Board of Trustees
has the power to designate one or more series or sub-series/classes of
 
                                      27
<PAGE>
 
shares of beneficial interest and to classify or reclassify only unissued
shares with respect to such series. Shares of each series represent equal
proportionate interests in the assets of that series only and have identical
voting, dividend, redemption, liquidation, and other rights, except that only
shares of each Series' Brinson Fund-Class N and UBS Investment Funds class of
shares shall have voting rights with respect to the Rule 12b-1 plan relating
to such classes, respectively, as described below. All shares issued are fully
paid and non-assessable, and shareholders have no preemptive or other right to
subscribe to any additional shares and no conversion rights. Currently, the
Trust offers eight investment portfolios or series-Global Fund, Global Equity
Fund, Global Bond Fund, U.S. Balanced Fund, U.S. Equity Fund, U.S. Large
Capitalization Equity Fund, U.S. Bond Fund and Non-U.S. Equity Fund. Three
classes of shares are currently issued by the Trust for each Series, the
Brinson Fund-Class N, Brinson Fund-Class I and UBS Investment Funds class of
shares. Prior to September 15, 1998, the "UBS Investment Funds class" was
known as the "SwissKey Fund class."
 
VOTING RIGHTS
 
  Each issued and outstanding full and fractional share of a Series is
entitled to one full and fractional vote in the Series and all shares of each
Series participate equally with regard to dividends, distributions, and
liquidations with respect to that Series. Shareholders do not have cumulative
voting rights. On any matter submitted to a vote of shareholders, shares of
each Series will vote separately except when a vote of shareholders in the
aggregate is required by law, or when the Trustees have determined that the
matter affects the interests of more than one Series, in which case the
shareholders of all such Series shall be entitled to vote thereon. Only the
Brinson Fund-Class N shareholders may vote on matters related to the Plan
associated with that class and only the UBS Investment Funds shareholders may
vote on matters related to the 12b-1 plan associated with that class of
shares.
 
  As of August 18, 1998, Emjayco held of record more than 25% of the
outstanding shares of the Global Fund; Brinson Partners, Inc. held of record
more than 25% of the outstanding shares of the Global Equity Fund; Emjayco
held of record more than 25% of the outstanding shares of the Global Bond
Fund; Brinson Partners, Inc. held of record more than 25% of the outstanding
shares of the U.S. Balanced Fund; Merrill Lynch Trust Co. held of record more
than 25% of the outstanding shares of the U.S. Equity Fund; National Financial
Services Corporation held of record more than 25% of the outstanding shares of
the U.S. Large Capitalization Equity Fund; Brinson Partners, Inc. held of
record more than 25% of the outstanding shares of the U.S. Bond Fund; Emjayco
held of record more than 25% of the outstanding shares of the Non-U.S. Equity
Fund. A shareholder that holds such a percentage of the outstanding shares of
a class may be deemed a controlling person of that class under the Act.
 
SHAREHOLDER MEETINGS
 
  The Trustees of the Trust do not intend to hold annual meetings of
shareholders of the Series. The SEC, however, requires the Trustees to
promptly call a meeting for the purpose of voting upon the question of removal
of any Trustee when requested to do so by not less than 10% of the outstanding
shareholders of the respective Series. In addition, subject to certain
conditions, shareholders of each Series may apply to the Series to communicate
with other shareholders to request a shareholders' meeting to vote upon the
removal of a Trustee or Trustees.
 
PORTFOLIO TURNOVER (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND AND U.S.
BOND FUND)
 
  As a result of the investment policies of the Global Fund, Global Bond Fund,
U.S. Balanced Fund and U.S. Bond Fund, their portfolio turnover rates may
exceed 100%. High portfolio turnover (over 100%) may involve
 
                                      28
<PAGE>
 
correspondingly greater brokerage commissions and other transaction costs,
which will be borne directly by the Series and ultimately by the Series'
shareholders. In addition, high portfolio turnover may result in increased
short-term capital gains which, when distributed to shareholders, are treated
as ordinary income for tax purposes.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS
 
  The Trust will attempt to obtain the best overall price and most favorable
execution of transactions in portfolio securities. However, subject to
policies established by the Board of Trustees of the Trust, a Series may pay a
broker-dealer a commission for effecting a portfolio transaction for the
Series in excess of the amount of commission another broker-dealer would have
charged if Brinson Partners determines in good faith that the commission paid
was reasonable in relation to the brokerage or research services provided by
such broker-dealer, viewed in terms of that particular transaction or such
firm's overall responsibilities with respect to the clients, including the
Series, as to which it exercises investment discretion. In selecting and
monitoring broker-dealers and negotiating commissions, consideration will be
given to a broker-dealer's reliability, the quality of its execution services
on a continuing basis and its financial condition.
 
  When buying or selling securities, the Series may pay commissions to brokers
who are affiliated with the Advisor or the Series. The Series may purchase
securities in certain underwritten offerings for which an affiliate of the
Series or the Advisor may act as an underwriter. The Series may effect futures
transactions through, and pay commissions to, futures commission merchants who
are affiliated with the Advisor or the Series in accordance with procedures
adopted by the Board of Trustees of the Trust.
 
SHAREHOLDER REPORTS AND INQUIRIES
 
  Shareholders will receive semi-annual reports showing portfolio investments
and other information as of December 31 and annual reports audited by
independent auditors as of June 30. Shareholders with inquiries should call
The Brinson Funds at 1-800-448-2430 or write to The Brinson Funds, P.O. Box
2798, Boston, MA 02208-2798.
 
YEAR 2000 ISSUES
 
  Like other investment companies, as well as other financial and business
organizations around the world, the Trust could be adversely affected if the
computer systems used by the Advisor, MSTC, CGFSC and other service providers,
in performing their administrative functions for the Trust, do not properly
process and calculate date-related information and data as of and after
January 1, 2000. This is commonly known as the "Year 2000 Issue." The Year
2000 Issue, and, in particular, foreign service providers' responsiveness to
the issue, could affect portfolio and operational areas including securities
trade processing, interest and dividend payments, securities pricing,
shareholder account services, custody functions and others. The Advisor, MSTC
and CGFSC are taking steps that they believe are reasonably designed to
address the Year 2000 Issue with respect to computer systems that they use and
to obtain reasonable assurances that comparable steps are being taken by the
Trust's other service providers. These include identifying those systems that
may not function properly after December 31, 1999, and correcting or replacing
those systems. In addition, steps include testing the processing of Series
data on all systems relied on by the Advisor, MSTC and CGFSC. As of the date
of this Prospectus, however, there can be no assurance that these steps will
be sufficient to avoid any adverse impact to the Series.

PERFORMANCE INFORMATION
 
  From time to time, performance information, such as yield or total return,
may be quoted in advertisements or in communications to present or prospective
shareholders. Performance quotations represent the Funds' past performance and
should not be considered as representative of future results. The current
yield will be calculated by dividing the net investment income earned per
share by a Fund during the period stated in the advertisement (based on the
average daily number of shares entitled to receive dividends outstanding
during the period) by the maximum net asset value per share on the last day of
the period and annualizing the result on a semi-annual compounded basis. The
Funds' total return may be calculated on an annualized and aggregate basis for
various periods (which periods will be stated in the advertisement). Average
annual return reflects the average percentage change per year in value of an
investment in a Fund. Aggregate total return reflects the total percentage
change over the stated period.
 
  To help investors better evaluate how an investment in the Brinson Funds
might satisfy their investment objectives, advertisements regarding the Funds
may discuss yield or total return as reported by various financial
publications. Advertisements may also compare yield or total return to other
investments, indices and averages. The following publications, benchmarks,
indices and averages may be used: Lipper Mutual Fund Performance Analysis;
Lipper Fixed Income Analysis; Lipper Mutual Fund Indices; Morgan Stanley
Indices; Lehman Brothers Treasury Index; Salomon Brothers Indices; Dow Jones
Composite Average or its component indices; Standard & Poor's 500 Stock Index
or its component indices; Wilshire Indices; The New York Stock Exchange
composite or component indices; CDA Mutual Fund Report; Weisenberger-Mutual
Funds Panorama and Investment Companies; Mutual Fund Values and Mutual Fund
Service Book, published by Morningstar, Inc.; comparable portfolios managed by
the Advisor; and financial publications, such as Business Week, Kiplinger's
Personal Finance, Financial World, Forbes, Fortune, Money Magazine, The Wall
Street Journal, Barron's, et al., which rate fund performance over various
time periods.
 
  The principal value of an investment in the Funds will fluctuate, so that an
investor's shares, when redeemed, may be worth more or less than their
original cost. Any fees charged by banks or other institutional investors
directly to their customer accounts in connection with investments in shares
of the Funds will not be included in the Brinson Funds' calculations of yield
or total return. Further information about the performance of the Funds is
included in the Funds' Annual Report dated June 30, 1998, which may be
obtained without charge by contacting the Trust at 1-800-448-2430.

APPENDIX A
 
INVESTMENT POLICIES AND TECHNIQUES
 
  EQUITY SECURITIES (GLOBAL FUND, GLOBAL EQUITY FUND, U.S. BALANCED FUND, U.S.
EQUITY FUND, U.S. LARGE CAPITALIZATION EQUITY FUND, AND NON-U.S. EQUITY FUND):
The Series may invest in a broad range of equity securities of U.S. and non-
U.S. issuers, including common stocks of companies or closed-end investment
companies, preferred stocks, debt securities convertible into or exchangeable
for common stock, securities such as warrants or rights that are convertible
into common stock and sponsored or unsponsored American, European and Global
depositary receipts ("Depositary Receipts"). The issuers of unsponsored
Depositary Receipts are not obligated to disclose material information in the
United States. The Series expect their U.S. equity investments to emphasize
large and intermediate capitalization companies, although the Global Fund may
also invest in small capitalization equity markets. The equity markets in the
non-U.S. component of the Series will typically include available shares of
larger capitalization companies. Capitalization levels are measured relative
to specific markets, thus large, intermediate and small capitalization ranges
vary country by country. The Global Fund may invest in equity securities of
companies considered by the Advisor to be in their post-venture capital stage,
or "post-venture capital companies." A post-venture capital company is a
company that has received venture capital financing either (a) during the
early stages of the company's existence or the early stages of the development
of a new product or service, or (b) as part of a restructuring or
recapitalization of the company. The Global Fund also may invest in open-end
investment companies advised by Brinson Partners, in equity securities of
issuers in emerging markets and in securities with respect to which the return
is derived from the equity securities of issuers in emerging markets.
 
  FIXED INCOME SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND): The Series may invest in a broad range of fixed income
securities of U.S. and non-U.S. issuers, including governments and
governmental entities, supranational issuers as well as corporations and other
business organizations. The Series may purchase U.S. dollar denominated
securities that reflect a broad range of investment maturities, qualities and
sectors. A majority of the fixed income securities in which the Series will
invest will possess a minimum rating of BBB- by S&P or Baa3 by Moody's or, if
unrated, will be determined to be of comparable quality by Brinson Partners.
Such securities are considered to be investment grade. While securities rated
BBB- or Baa3 are regarded as having an adequate capacity to pay principal and
interest, such bonds lack outstanding investment characteristics and, in fact,
have speculative characteristics; and changes in economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than is the case with higher rated bonds. Securities
rated lower than BBB- by S&P and Baa3 by Moody's are classified as non-
investment grade securities (commonly referred to as "junk bonds"), carry a
higher degree of risk and are considered to be speculative by the major credit
rating agencies. Each Series currently intends to limit its aggregate
investment in non-investment grade debt securities of its U.S. and non-U.S.
dollar denominated fixed income assets to no more than 5% of its net assets.
To the extent that a security held by a Series is downgraded to below
investment grade, the Series will dispose of that or another non-investment
grade security so that no more than 5% of its assets will be invested in below
investment grade securities. Other fixed income securities in which the Series
may invest include zero coupon securities, mortgage-backed securities, asset-
backed securities and when-issued securities.
 
  The non-U.S. fixed income component of the Series will typically be invested
in the securities of non-U.S. governments, governmental agencies and
supranational issues. A supranational entity is an entity established or
financially supported by the national governments of one or more countries to
promote reconstruction or development. Examples of supranational entities
include, among others: the World Bank, the European
 
                                      31
<PAGE>
 
Economic Community, the European Coal and Steel Community, the European
Investment Bank, the Inter-American Development Bank, the Export-Import Bank
and the Asian Development Bank.
 
  The Global Fund may invest in fixed income securities of emerging market
issuers, including government and government-related entities (including
participation in loans between governments and financial institutions), and of
entities organized to restructure outstanding debt securities of developing
countries' corporate issuers.
 
  CASH AND CASH EQUIVALENTS (ALL SERIES): The Series may invest a portion of
their assets in short-term debt securities (including repurchase agreements
and reverse repurchase agreements) of corporations, the U.S. government and
its agencies and instrumentalities and banks and finance companies, which may
be denominated in any currency. When unusual market conditions warrant, a
Series may make substantial temporary defensive investments in cash
equivalents up to a maximum of 100% of its net assets. Cash equivalent
holdings may be in any currency (although such holdings may not constitute
"cash or cash equivalents" for tax diversification purposes under the Code).
When a Series invests for defensive purposes, it may affect the attainment of
the Series' investment objective.
 
  Under the terms of an exemptive order issued by the SEC, each Series may
invest cash (i) held for temporary defensive purposes; (ii) not invested
pending investment in securities; (iii) that is set aside to cover an
obligation or commitment of the Series to purchase securities or other assets
at a later date; (iv) to be invested on a strategic management basis (i-iv is
herein referred to as "Uninvested Cash"); and (v) collateral that it receives
from the borrowers of its portfolio securities in connection with the Series'
securities lending program, in a series of shares of Brinson Supplementary
Trust (the "Supplementary Trust Series"). Brinson Supplementary Trust is a
private investment company which has retained the Advisor to manage its
investments. The Trustees of the Trust also serve as Trustees of the Brinson
Supplementary Trust. The Supplementary Trust Series will invest in U.S. dollar
denominated money market instruments having a dollar-weighted average maturity
of 90 days or less. A Series' investment of Uninvested Cash in shares of the
Supplementary Trust Series will not exceed 25% of the Series' total assets. In
the event that the Advisor waives 100% of its investment advisory fee with
respect to a Series, as calculated monthly, then that Series will be unable to
invest in the Supplementary Trust Series until additional investment advisory
fees are owed by the Series.
 
  ZERO COUPON SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND): Zero coupon securities are debt obligations which do not
entitle the holder to any periodic payments of interest prior to maturity or a
specified date when the securities begin paying current interest (the "cash
payment date") and, therefore, are issued and traded at a discount from their
value at maturity or par value. Such bonds carry an additional risk in that,
unlike bonds which pay interest throughout the period to maturity, a Series
investing in zero coupon securities will realize no cash until the cash
payment date and, if the issuer defaults, a Series may obtain no return at all
on its investment. The market price of zero coupon securities generally is
more volatile than the market price of securities that pay interest
periodically and are likely to be more responsive to changes in interest rates
than non-zero coupon securities having similar maturities and credit
qualities. For federal tax purposes, the Series will be required to include in
income daily portions of original issue discount accrued and to distribute the
same to shareholders annually, even if no payment is received before the
distribution date.
 
  MORTGAGE- AND ASSET-BACKED SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S.
BALANCED FUND AND U.S. BOND FUND): Mortgage-backed securities represent direct
or indirect participations in, or are secured by and payable from, pools of
mortgage loans secured by real property, and include single- and multi-class
pass-through securities and collateralized mortgage obligations. These
securities may be issued or guaranteed by
 
                                      32
<PAGE>
 
agencies or instrumentalities of the U.S. government. Other mortgage-backed
securities are issued by private issuers, generally originators of and
investors in mortgage loans, including savings associations, mortgage bankers,
commercial banks, investment bankers and special purpose entities
(collectively, "private lenders"). Mortgage-backed securities issued by
private lenders may be supported by pools of mortgage loans or other mortgage-
backed securities that are guaranteed, directly or indirectly, by the U.S.
government or one of its agencies or instrumentalities, or they may be issued
without any governmental guarantee of the underlying mortgage assets but with
some form of non-governmental credit enhancement.
 
  Asset-backed securities have structural characteristics similar to mortgage-
backed securities. However, the underlying assets are not first-lien mortgage
loans or interests therein; rather, they include assets such as motor vehicle
installment sales contracts, other installment loan contracts, home equity
loans, leases of various types of property and receivables from credit card or
other revolving credit arrangements. Payments or distributions of principal
and interest on asset-backed securities may be supported by non-governmental
credit enhancements similar to those utilized in connection with mortgage-
backed securities.
 
  The yield characteristics of mortgage- and asset-backed securities differ
from those of traditional debt obligations. Among the principal differences
are that interest and principal payments are made more frequently on mortgage-
and asset-backed securities, usually monthly, and that principal may be
prepaid at any time because the underlying mortgage loans or other assets
generally may be prepaid at any time. As a result, the rate of return on these
securities may be affected by prepayments of principal on the underlying
loans, which generally increase as interest rates decline. As a result, if a
Series purchases these 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 a Series purchases these securities at a discount,
a prepayment rate that is faster than expected will increase yield to
maturity, while a prepayment rate that is slower than expected will reduce
yield to maturity. Accelerated prepayments on securities purchased by a Series
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 prepaid in full. In
addition, like other debt securities, the values of mortgage-related
securities, including government and government-related mortgage pools,
generally will fluctuate in response to market interest rates. The market for
privately issued mortgage- and asset-backed securities is smaller and less
liquid than the market for government sponsored mortgage-backed securities.
 
  WHEN-ISSUED SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND): The Series may purchase securities on a "when-issued"
basis for payment and delivery at a later date. The price is generally fixed
on the date of commitment to purchase. During the period between purchase and
settlement, no interest accrues to a Series. At the time of settlement, the
market value of the security may be more or less than the purchase price. The
Series will establish a segregated account consisting of cash, U.S. government
securities, equity securities and/or investment and non-investment grade debt
securities in accordance with SEC positions. The cash, U.S. government
securities, equity securities, investment or non-investment grade debt
securities and other assets held in any segregated account maintained by the
Series with respect to any when-issued securities, options, futures, forward
contracts or other derivative transactions shall be liquid, unencumbered and
marked-to-market daily (the assets held in a segregated account are referred
to in this Prospectus as "Segregated Assets"), and such Segregated Assets
shall be maintained in accordance with pertinent positions of the SEC.
 
  FOREIGN CURRENCY TRANSACTIONS (GLOBAL FUND, GLOBAL EQUITY FUND, GLOBAL BOND
FUND AND NON-U.S. EQUITY FUND): The Series may conduct their foreign currency
exchange transactions on a spot (i.e., cash) basis at the spot rate prevailing
in the foreign currency exchange market or through entering into contracts to
purchase
 
                                      33
<PAGE>
 
or sell foreign currencies at a future date (i.e., a "forward foreign
currency" contract or "forward" contract). A forward contract involves an
obligation to purchase or sell a specific currency amount 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. The Series
will convert currency on a spot basis from time to time and investors should
be aware that changes in currency exchange rates and exchange control
regulations may affect the costs of currency conversion.
 
  The Series may enter into forward contracts for hedging purposes as well as
non-hedging purposes. For hedging purposes, a Series may enter into contracts
to deliver or receive foreign currency it will receive from or require for its
normal investment activities. It may also use contracts in a manner intended
to protect foreign currency-denominated securities from declines in value due
to unfavorable exchange rate movements. A Series may also enter into contracts
with the intent of changing the relative exposure of the Series' portfolio of
securities to different currencies to take advantage of anticipated changes in
exchange rates.
 
  When a Series enters into forward contracts for non-hedging purposes, it
will establish a segregated account with its custodian bank in which it will
maintain Segregated Assets in accordance with SEC positions.
 
  At the maturity of a forward contract, a Series may either sell a portfolio
security and make delivery of the foreign currency, or it may retain the
security and terminate its contractual obligation to deliver the foreign
currency by purchasing an "offsetting" contract with the same currency trader,
obligating it to purchase, on the same maturity date, the same amount of the
foreign currency. A Series may realize a gain or loss from currency
transactions.
 
  OPTIONS ON CURRENCIES (GLOBAL FUND, GLOBAL EQUITY FUND, GLOBAL BOND FUND AND
NON-U.S. EQUITY FUND): The Series also may purchase and write put and call
options on foreign currencies (traded on U.S. and foreign exchanges or over-
the-counter markets) to manage the respective portfolio's exposure to changes
in currency exchange rates. Call options on foreign currency written by a
Series will be "covered," which means that the Series will own an equal amount
of, or an offsetting position in, the underlying foreign currency. With
respect to put options on foreign currency written by a Series, the Series
will establish a segregated account with its custodian bank consisting of
Segregated Assets in accordance with SEC positions.
 
  FUTURES CONTRACTS (ALL SERIES): The Series may enter into contracts for the
future purchase or sale of securities and indices. The Global Funds and the
Non-U.S. Equity Fund also may enter into contracts for the future purchase or
sale of foreign currencies. A financial futures contract is an agreement
between two parties to buy or sell a specified debt security at a set price on
a future date. An index futures contract is an agreement to take or make
delivery of an amount of cash based on the difference between the value of the
index at the beginning and at the end of the contract period. A futures
contract on a foreign currency is an agreement to buy or sell a specified
amount of a currency for a set price on a future date. A Series may enter into
a futures contract to the extent that not more than 5% of its assets are
required as futures contract margin deposits and its obligations relating to
such futures transactions represent not more than 25% of the Series' assets.
The Series may also effect futures transactions through futures commission
merchants who are affiliated with the Advisor or the Series in accordance with
procedures adopted by the Board of Trustees.
 
  The Global Fund, Global Equity Fund, Global Bond Fund and Non-U.S. Equity
Fund will enter into such futures transactions on domestic exchanges and, to
the extent such transactions have been approved by the Commodity Futures
Trading Commission for sale to customers in the United States, on foreign
exchanges.
 
                                      34
<PAGE>
 
  OPTIONS (ALL SERIES): The Series may purchase and write put and call options
on foreign or U.S. securities and indices and enter into related closing
transactions. A Series' may use options traded on U.S. exchanges and, to the
extent permitted by law, options traded over-the-counter and recognized
foreign exchanges. It is the position of the U.S. Securities and Exchange
Commission that over-the-counter options are illiquid. Accordingly, a Series
will invest in such options only to the extent consistent with its 15% limit
on investment in illiquid securities.
 
  REPURCHASE AGREEMENTS (ALL SERIES): The Series may enter into repurchase
agreements with banks or broker-dealers. Repurchase agreements are considered
under the Act to be collateralized loans by a Series to the seller secured by
the securities transferred to the Series. Repurchase agreements under the Act
will be fully collateralized by securities which the Series may invest in
directly. Such collateral will be marked-to-market daily. If the seller of the
underlying security under the repurchase agreement should default on its
obligation to repurchase the underlying security, the Series may experience
delay or difficulty in recovering its cash. To the extent that, in the
meantime, the value of the security purchased had decreased, the Series could
experience a loss. No more than 15% of a Series' net assets will be invested
in illiquid securities, including repurchase agreements which have a maturity
of longer than seven days. The Series must treat each repurchase agreement as
a security for tax diversification purposes and not as cash, a cash equivalent
or as a receivable.
 
  BORROWING (ALL SERIES): Each Series is authorized, within specified limits,
to borrow money as a temporary defensive measure for extraordinary purposes
and to pledge its assets in connection with such borrowings.
 
  LOANS OF PORTFOLIO SECURITIES (ALL SERIES): Each Series may loan its
portfolio securities to broker-dealers and other institutional investors
pursuant to agreements requiring that the loans be continuously secured by
collateral equal at all times in value to at least the market value of the
securities loaned. The major risk to which a Series would be exposed on a loan
transaction is the risk that the borrower would become bankrupt at a time when
the value of the security goes up. Therefore, a Series will only enter into
loan arrangements after a review of all pertinent factors by Brinson Partners,
subject to overall supervision by the Board of Trustees, including the
creditworthiness of the borrowing broker-dealer or institution and then only
if the consideration to be received from such loans would justify the risk.
Creditworthiness will be monitored on an ongoing basis by Brinson Partners.
 
  RULE 144A AND ILLIQUID SECURITIES (ALL SERIES): Each Series may invest up to
15% of its net assets in illiquid securities. Illiquid securities are those
securities that are not readily marketable, including restricted securities
and repurchase obligations that mature in more than seven days. Certain
restricted securities that may be resold to institutional investors pursuant
to Rule 144A under the Securities Act of 1933 may be determined to be liquid
under guidelines adopted by the Trust's Board of Trustees.
 
  INVESTMENT COMPANY SECURITIES (GLOBAL FUND): The Trust has received an
exemptive order (the "Exemptive Order") from the SEC which permits each Series
to invest its assets in certain portfolios of Brinson Relationship Funds,
another registered investment company advised by Brinson Partners. Currently,
only the Global Fund intends to invest in the portfolios of Brinson
Relationship Funds and only to the extent consistent with Brinson Partners'
investment process of allocating assets to specific asset classes. The Global
Fund will invest in the portfolios of Brinson Relationship Funds to obtain
exposure to the following asset classes: (1) equity and fixed income
securities of issuers located in emerging market countries ("Emerging Market
Securities"); (2) equity securities issued by companies with relatively small
overall market capitalizations ("Small Cap Securities"); and (3) high yield
securities ("High Yield Securities"). The Global Fund will invest in
corresponding portfolios of Brinson Relationship Funds only to the extent the
Advisor determines that such investments are a more efficient
 
                                      35
<PAGE>
 
means for the Global Fund to gain exposure to the asset classes identified
above than by investing directly in individual securities. Thus, to gain
exposure to Emerging Market Securities, the Global Fund will invest in the
Brinson Emerging Markets Equity Fund and the Brinson Emerging Markets Debt
Fund portfolios of Brinson Relationship Funds. To gain exposure to Small Cap
Securities and High Yield Securities, the Global Fund will invest in the
Brinson Post-Venture Fund and the Brinson High Yield Fund portfolios,
respectively, of Brinson Relationship Funds. Each portfolio of Brinson
Relationship Funds in which the Global Fund may invest is permitted to invest
in the same securities of a particular asset class in which the Global Fund is
permitted to invest directly, and with similar risks.
 
  RUSSIAN SECURITIES (GLOBAL FUND): The Series may invest in securities of
Russian companies. The registration, clearing and settlement of securities
transactions in Russia are subject to significant risks not normally
associated with securities transactions in the United States and other more
developed markets. Ownership of shares of Russian companies is evidenced by
entries in a company's share register (except where shares are held through
depositories that meet the requirements of the Act) and the issuance of
extracts from the register or, in certain limited cases, by formal share
certificates. However, Russian share registers are frequently unreliable and
the Series could possibly lose its registration through oversight, negligence
or fraud. Moreover, Russia lacks a centralized registry to record securities
transactions and registrars located throughout Russia or the companies
themselves maintain share registers. Registrars are under no obligation to
provide extracts to potential purchasers in a timely manner or at all and are
not necessarily subject to state supervision. In addition, while registrars
are liable under law for losses resulting from their errors, it may be
difficult for the Series to enforce any rights it may have against the
registrar or issuer of the securities in the event of loss of share
registration. Although Russian companies with more than 1,000 shareholders are
required by law to employ an independent company to maintain share registers,
in practice, such companies have not always followed this law. Because of this
lack of independence of registrars, management of a Russian company may be
able to exert considerable influence over who can purchase and sell the
company's shares by illegally instructing the registrar to refuse to record
transactions on the share register. Furthermore, these practices may prevent
the Series from investing in the securities of certain Russian companies
deemed suitable by the Advisor and could cause a delay in the sale of Russian
securities by the Fund if the company deems a purchaser unsuitable, which may
expose the Fund to potential loss on its investment.
 
  In light of the risks described above, the Board of Trustees of the Series
has approved certain procedures concerning the Series' investments in Russian
securities. Among these procedures is a requirement that the Series will not
invest in the securities of a Russian company unless that issuer's registrar
has entered into a contract with the Series' sub-custodian containing certain
protective conditions including, among other things, the sub-custodian's right
to conduct regular share confirmations on behalf of the Series. This
requirement will likely have the effect of precluding investments in certain
Russian companies that the Series would otherwise make.
 
  For more detailed descriptions of these investment policies and techniques,
please refer to the Statement of Additional Information, which is available
without charge upon request by calling 1-800-448-2430.

/1/Pursuant to the terms of the Investment Advisory Agreements between the
   Trust on behalf of each Series and the Advisor, the Advisor is to receive a
   monthly fee at the following annual rates for each of the Global Fund,
   Global Equity Fund, Global Bond Fund, U.S. Balanced Fund, U.S. Equity Fund,
   U.S. Large Capitalization Equity Fund, U.S. Bond Fund and Non-U.S. Equity
   Fund: 0.80%, 0.80%, 0.75%, 0.70%, 0.70%, 0.70%, 0.50% and 0.80%,
   respectively. Brinson Partners has agreed irrevocably to waive its fees and
   reimburse certain expenses so that total operating expenses, with the
   exception of 12b-1 expenses, of the Global Fund, Global Equity Fund, Global
   Bond Fund, U.S. Balanced Fund, U.S. Equity Fund, U.S. Large Capitalization
   Equity Fund, U.S. Bond Fund and Non-U.S. Equity Fund will never exceed
   1.10%, 1.00%, 0.90%, 0.80%, 0.80%, 0.80%, 0.60% and 1.00%, respectively.
   Absent these fee waivers and expense reimbursements, the total operating
   expenses for the UBS Investment Fund class shares of the Series for the
   fiscal year ended June 30, 1998 would have been 1.78% Global Equity Fund,
   1.45% Global Bond Fund, 1.31% U.S. Balanced Fund, 2.11% U.S. Large Equity
   Capitalization Fund and 1.31% U.S. Bond Fund. The fees and expenses for the
   U.S. Large Capitalization Equity Fund are based on the period from April 6,
   1998 (commencement of operations) to June 30, 1998.
 
/2/For purposes of this Table, "12b-1 Expenses" is comprised of an asset-based
   sales charge of up to 0.65% of average daily net assets and a service fee
   of 0.25% of average daily net assets for UBS Investment Fund class shares
   of each Series. See "Distribution Plan." Although the Distribution Plan
   relating to the UBS Investment Funds (the "Plan") provides that the Trust
   may pay up to an annual rate of 0.65% of the average daily net assets of
   the UBS Investment Fund class shares, plus a 0.25% service fee for each UBS
   Investment Fund ("distribution fees"), the Trust and the Underwriter have
   agreed to limit aggregate distribution fees with respect to UBS Investment
   Fund class shares so as not to exceed 0.65%, 0.76%, 0.49%, 0.50%, 0.52%,
   0.52%, 0.47% and 0.84% of the average daily net assets of the UBS
   Investment Fund-Global, UBS Investment Fund-Global Equity, UBS Investment
   Fund-Global Bond, UBS Investment Fund-U.S. Balanced, UBS Investment Fund-
   U.S. Equity, UBS Investment Fund-U.S. Large Capitalization Equity, UBS
   Investment Fund-U.S. Bond and UBS Investment Fund-Non-U.S. Equity,
   respectively.
   
  Pursuant to rules of the National Association of Securities Dealers, Inc.
("NASD"), the aggregate initial sales charges, deferred sales charges and
asset-based sales charges on shares of the Funds may not exceed 6.25% of total
gross sales, subject to certain exclusions. This 6.25% limitation is imposed
on the Fund rather than on a per shareholder basis. Therefore, long-term
shareholders of the UBS Investment Funds may pay more than the economic
equivalent of the maximum front-end sales charges permitted by the NASD. This
amount also includes service fees.

EXAMPLE: Based on the level of expenses listed above after fee waivers and
reimbursements, the total expenses relating to an investment of $1,000 would
be as follows assuming a 5% annual return and redemption at the end of each
time period.

PRIOR PERFORMANCE OF ADVISOR
 
  The following table sets forth the Advisor's performance data relating to
the historical performance of funds contained within an institutional
collective investment trust ("CIT") (described below) managed by the Advisor.
Such CITs have investment objectives, policies, strategies and risks
substantially similar to those of the various Series of the Trust. The data is
provided to illustrate the past performance of the Advisor in managing
investment portfolios which are substantially similar to each applicable
Series of the Trust as measured against specified market indices. The
performance data of the UBS Investment Funds class of shares of each Series of
the Trust is also included in the table.
 
  The Advisor adopted the Performance Presentation Standards of the
Association for Investment Management and Research (AIMR Standards) as of
January 1, 1993. The CIT returns presented in this Prospectus are the
responsibility of the Advisor. They are presented in compliance with the
Performance Presentation Standards of the Association for Investment
Management and Research (AIMR--PPS(TM)). AIMR has not been involved with the
preparation or review of these returns.
 
  Investment results are time-weighted performance calculations representing
total return. Returns are calculated using geometric linking of monthly
returns. Each composite is a single entity composite, consisting of the assets
of each applicable fund of the Brinson Trust Company Collective Investment
Trust for Pension and Profit Sharing Trusts, or its predecessors, which may be
a single client. Clients must be an ERISA or governmental employee benefit
plan in order to qualify to invest in a CIT. Composites are valued monthly,
taking into account cash flows. All realized and unrealized capital gains and
losses, as well as all dividends and interest from investments and cash
balances, are included. Investment transactions are accounted for on a trade
date basis. Total returns for the CIT composites exclude the impact of
administrative expenses and the impact of any income taxes an investor might
have incurred as a result of taxable ordinary income and capital gains
realized by the CIT.
 
  The composite for each CIT is composed of all actual fee-paying,
discretionary client portfolios invested in the CIT. No alterations of
composites as presented here have occurred due to changes in personnel.
Accounts of all sizes invested in each CIT are included in composite
performance and no minimum account relationship size was set for inclusion in
the composites as the individual account size does not impact portfolio
management style. CITs are not subject to certain expenses, investment
limitations, diversification requirements and restrictions to which the Series
are subject and which are imposed by the Investment Company Act of 1940 (the
"Act") and the Internal Revenue Code of 1986, as amended. Had such expenses,
limitations, requirements and restrictions been applicable to the CITs, the
performance results of the CIT composites could have been adversely affected.
The CITs' performance presented does not represent the historical performance
of the Series and should not be interpreted as indicative of future
performance of the Series.

DESCRIPTION OF THE FUNDS
 
  The investment objective of each Series is fundamental and may not be
changed without a vote of the holders of the majority of the voting securities
of the Series. Unless otherwise stated in this Prospectus or the Statement of
Additional Information, each Series' investment policies are not fundamental
and may be changed without shareholder approval. There can be no assurance
that the Series will achieve their investment objectives.
 
  The Series do not intend to concentrate their investments in a particular
industry. None of the Series intends to issue senior securities as defined in
the Act, except that each Series may engage in borrowing activities as defined
in Appendix A and in the Statement of Additional Information. Each Series'
investment objective and its policies concerning portfolio lending, borrowing,
the issuance of senior securities and concentration are "fundamental," which
means that they may not be changed without the affirmative vote of the holders
of a majority of the Series' outstanding voting securities (as defined in the
Act).
 
INVESTMENT OBJECTIVES AND POLICIES
 
GLOBAL FUND
 
INVESTMENT OBJECTIVE
 
  The Global Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income. The Series will attempt
to control risk while seeking to achieve its investment objective. As a global
fund, at least 65% of the Series' total assets will be invested in securities
of issuers in at least three countries, one of which may be the United States.
The Series may utilize a wide range of equity, debt and money market
securities in domestic and foreign markets, and the Series may invest in other
open-end investment companies advised by Brinson Partners. The Series may
enter into repurchase agreements and reverse repurchase agreements, and engage
in futures, options and currency transactions for hedging and other
permissible purposes, as more fully described in "Investment Considerations
and Risks" and Appendix A in this Prospectus, and in the Statement of
Additional Information.
 
  The Series is a diversified portfolio that seeks to achieve its objective by
pursuing active asset allocation strategies across global equity and fixed
income markets and active security selection within each market. These
decisions are undertaken relative to the GSMI Mutual Fund Index (the "Global
Benchmark"), which is compiled by Brinson Partners. The Global Benchmark
consists of eight distinct asset classes representing the primary wealth-
holding public securities markets. These asset classes are U.S. equities, non-
U.S. equities, emerging markets equities, U.S. bonds, non-U.S. bonds, emerging
markets bonds, high yield bonds and cash equivalents. Each asset class is
represented in the Global Benchmark by an index compiled by an independent
data provider. In order to compile the Global Benchmark, the Advisor
determines current relative market capitalizations in the world markets (U.S.
equities, non-U.S. equities, emerging markets equities, U.S. bonds, non-U.S.
bonds, emerging markets bonds, high yield bonds and cash) and then weights
each relevant index. Based on this weighting, the Advisor determines the
return of the relative indices, applies the index weighting and then
determines the return of the Global Benchmark. From time to time, the Advisor
may substitute an equivalent index within a given asset class when it believes
that such index more accurately reflects the relevant global market.
 
 
  Although it may invest anywhere in the world, it is expected that the
Series' assets will be primarily invested in equity markets listed in the
Morgan Stanley Capital International ("MSCI") World Equity (Free) Index. The
 
                                       9
<PAGE>
 
Series will primarily invest in fixed income markets listed in the Salomon
World Government Bond Index. The Series may invest up to 10% of its net assets
in equity and debt securities of emerging market issuers, or securities with
respect to which the return is derived from the equity or debt securities of
issuers in emerging markets.
 
GLOBAL EQUITY FUND
 
INVESTMENT OBJECTIVE
 
  The Global Equity Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income. The Series will attempt
to control risk while seeking to achieve its investment objective. As a global
fund, at least 65% of the Series' total assets will be invested in equity
securities of issuers in at least three countries, one of which may be the
United States. The Series may utilize a wide range of equity securities that
are traded on both domestic and foreign stock exchanges or, in the case of
domestic stocks, in the over-the-counter market. The Series may enter into
repurchase agreements and reverse repurchase agreements, and engage in
futures, options and currency transactions for hedging and other permissible
purposes, as more fully described in "Investment Considerations and Risks" and
Appendix A in this Prospectus, and in the Statement of Additional Information.
 
  The Series is a diversified portfolio that seeks to achieve its objective by
pursuing an active asset allocation strategy across global equity markets,
active management of currency exposures and active security selection within
each market. The benchmark for the Series is the MSCI World Equity (Free)
Index (the "Global Equity Benchmark"). The Global Equity Benchmark is a market
driven broad based index which includes U.S. and non-U.S. equity markets in
terms of capitalization and performance. The Global Equity Benchmark is
designed to provide a representative total return for all major stock
exchanges located inside and outside the United States. Although it may invest
anywhere in the world, it is expected that the Series' assets will primarily
be invested in equity markets listed in the Global Equity Benchmark. From time
to time, the Advisor may substitute securities in an equivalent index when it
believes that such securities in the index more accurately reflect the
relevant global market.
 
GLOBAL BOND FUND
 
INVESTMENT OBJECTIVE
 
  The Global Bond Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income. The Series will attempt
to control risk while seeking to achieve its investment objective. As a global
fund, at least 65% of the Series' total assets will be invested in debt
securities with an initial maturity of more than one year of issuers in at
least three countries, one of which may be the United States. The Series seeks
to achieve this objective by investing primarily in debt securities that may
also provide the potential for capital appreciation. The Series may enter into
repurchase agreements and reverse repurchase agreements, and may engage in
futures, options and currency transactions for hedging and other permissible
purposes, as more fully described in "Investment Considerations and Risks" and
Appendix A in this Prospectus, and in the Statement of Additional Information.
 
  The Series is a non-diversified portfolio as described in "Investment
Considerations and Risks-Non-Diversified Status". The benchmark for the Series
is the Salomon World Government Bond Index (the "Global Bond Benchmark"). The
Global Bond Benchmark is a market driven index which measures the broad global
fixed income markets invested in debt issues of U.S. and non-U.S. governments,
governmental entities and supranationals. Although it may invest anywhere in
the world, it is expected that the Series' assets will be primarily invested
in fixed income markets listed in the Global Bond Benchmark. From time to
time, the Advisor may substitute securities in an equivalent index when it
believes that such securities in the index more accurately reflect the
relevant global fixed income securities market.

U.S. BALANCED FUND
 
INVESTMENT OBJECTIVE
 
  The U.S. Balanced Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income. The Series will attempt
to control risk while seeking to achieve its investment objective. Under
normal circumstances, the Series will invest at least 25% of its net assets in
fixed income securities. The Series may utilize a wide range of equity, debt
and money market securities. The Series may also invest in equity securities,
including warrants, preferred stock and securities convertible into equity
securities. The Series may enter into repurchase agreements and reverse
repurchase agreements, and may engage in futures and options for hedging and
other permissible purposes, as more fully described in "Investment
Considerations and Risks" and Appendix A in this Prospectus, and in the
Statement of Additional Information. It is not the policy of the Series to
take unreasonable risks to obtain speculative or aggressively high returns.
 
  The Series is a diversified portfolio that seeks to achieve its objective by
pursuing active asset allocation strategies across U.S. equity and fixed
income markets and active security selection within each market. These
decisions are undertaken relative to the U.S. Balanced Mutual Fund Index (the
"U.S. Balanced Benchmark"), which is compiled by Brinson Partners. The U.S.
Balanced Benchmark represents a fixed composite of 65% Wilshire 5000 Index and
35% Salomon Brothers Broad Investment Grade (BIG) Bond Index. From time to
time, the Advisor may substitute an equivalent index within a given asset
class when the Advisor believes that such new index more accurately reflects
the relevant U.S. market.
 
U.S. EQUITY FUND
 
INVESTMENT OBJECTIVE
 
  The U.S. Equity Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income, while controlling risk.
Under normal circumstances, at least 65% of the Series' total assets will be
invested in equity securities of U.S. companies. The Series is a diversified
portfolio that seeks to achieve its objective by investing in a wide range of
equity securities of U.S. companies that are traded on major stock exchanges
as well as in the over-the-counter market. The Series may engage in futures
and options for hedging and other permissible purposes, as more fully
described in "Investment Considerations and Risks" and Appendix A in this
Prospectus, and in the Statement of Additional Information. The benchmark for
the Series is the Wilshire 5000 Index (the "U.S. Equity Benchmark"). The U.S.
Equity Benchmark is a broad weighted index which includes all U.S. common
stocks. The U.S. Equity Benchmark is designed to provide a representative
indication of the capitalization and return for the U.S. equity market.
 
U.S. LARGE CAPITALIZATION EQUITY FUND
 
INVESTMENT OBJECTIVE
 
  The U.S. Large Capitalization Equity Fund's investment objective is to
maximize total return, consisting of capital appreciation and current income,
while controlling risk. Under normal circumstances, at least 65% of the
Series' total assets will be invested in large capitalization equity
securities of U.S. companies. The Advisor defines large capitalization
companies as those with market capitalizations in the upper 65% of the
Wilshire 5000 Index at the time of the Series' investment. Companies whose
capitalization falls below this level after purchase continue to be considered
large capitalization companies. The Series is a non-diversified portfolio as
described in "Investment Considerations and Risks--Non-Diversified Status."
The Series seeks to achieve its objective by investing in a wide range of
equity securities of U.S. companies that are traded on major stock exchanges
as well as in the over-the-counter market. The Series may engage in futures
and options for hedging and other
 
                                      11
<PAGE>
 
permissible purposes, as more fully described in "Investment Considerations
and Risks" and Appendix A in this Prospectus, and in the Statement of
Additional Information. The benchmark for the Series is the Standard & Poor's
500 Stock Index (the "U.S. Large Capitalization Equity Benchmark"). The U.S.
Large Capitalization Equity Benchmark is a broad weighted index which includes
primarily U.S. common stocks. The U.S. Large Capitalization Equity Benchmark
is designed to provide a representative indication of the capitalization and
return for the large capitalization U.S. equity market.
 
U.S. BOND FUND
 
INVESTMENT OBJECTIVE
 
  The U.S. Bond Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income, while controlling risk.
As a matter of fundamental policy, under normal circumstances, the Series
intends to invest at least 65% of its total assets in U.S. debt securities
with an initial maturity of more than one year. The Series is a diversified
portfolio that seeks to achieve its objective by investing primarily in fixed
income securities, which may also provide the potential for capital
appreciation. The Series may also engage in futures and options transactions
for hedging and other permissible purposes, as more fully described in
"Investment Considerations and Risks" and Appendix A in this Prospectus, and
in the Statement of Additional Information.
 
  The Series may invest in a broad range of fixed income securities, including
debt securities of the U.S. government, together with its agencies and
instrumentalities and the debt securities of U.S. corporations. A majority of
the fixed income securities in which the Series will invest will possess a
minimum rating of BBB- by Standard & Poor's Ratings Group ("S&P") or Baa3 by
Moody's Investors Services, Inc. ("Moody's") or, if unrated, will be
determined to be of comparable quality by Brinson Partners. Such securities
are considered to be investment grade. Other fixed income securities in which
the Series may invest include zero coupon securities, mortgage-backed
securities, asset-backed securities and when-issued securities. The Series may
invest a portion of its assets in short-term debt securities (including
repurchase and reverse repurchase agreements) of corporations, the U.S.
government or its agencies or instrumentalities, and banks and finance
companies.
 
  The benchmark for the Series is the Salomon Brothers Broad Investment Grade
(BIG) Bond Index (the "U.S. Bond Benchmark"). The U.S. Bond Benchmark is a
market driven broad based index which includes U.S. bonds with over one year
to maturity. From time to time, the Advisor may substitute securities in an
equivalent index when it believes that such securities in the index more
accurately reflect the relevant fixed income securities market.
 
NON-U.S. EQUITY FUND
 
INVESTMENT OBJECTIVE
 
  The Non-U.S. Equity Fund's investment objective is to maximize total return,
consisting of capital appreciation and current income, by investing primarily
in the equity securities of non-U.S. issuers. Under normal conditions, at
least 65% of the Series' total assets will be invested in equity securities of
issuers in at least three countries other than the United States. In seeking
to achieve its investment objective while controlling risk, the Series may
invest in a wide range of equity securities, including: American, European and
Global Depositary Receipts, common and preferred stock; debt securities
convertible into or exchangeable for common stock; and securities such as
warrants or rights that are convertible into common stock. The Series may
engage in futures, options and currency transactions for hedging and other
permissible purposes, as more fully described in "Investment Considerations
and Risks" and Appendix A in this Prospectus, and in the Statement of
Additional Information.

  The Series is a diversified portfolio that seeks to achieve its objective by
investing primarily in the equity securities of non-U.S. issuers. The
benchmark for the Series is the MSCI Non-U.S. Equity (Free) Index (the "Non-
U.S. Equity Benchmark"). The Non-U.S. Equity Benchmark is a market driven
broad based index which includes non-U.S. equity markets in terms of
capitalization and performance. From time to time, the Advisor may substitute
securities in an equivalent index when it believes that such securities in the
index more accurately reflect the relevant international market. Although it
may invest anywhere in the world, it is expected that the Series' assets will
be primarily invested in the equity markets included in the MSCI Non-U.S.
Equity (Free) Index.
 
INVESTMENT CONSIDERATIONS AND RISKS
 
  The following provides information about the types of instruments in which
the Series may invest, strategies employed by Brinson Partners in its attempt
to attain each Series' investment objective and a summary of related risks.
Shareholders should understand that all investments involve risks and there
can be no guarantee against loss resulting from an investment in the Series,
nor can there be any assurance that the Series will be able to attain their
investment objectives. A complete list of the Series' investment restrictions
and more detailed information about the Series' investments are contained in
Appendix A in this Prospectus, and in the Statement of Additional Information.
 
  EQUITY SECURITIES (GLOBAL FUND, GLOBAL EQUITY FUND, U.S. BALANCED FUND, U.S.
EQUITY FUND, U.S. LARGE CAPITALIZATION EQUITY FUND AND NON-U.S. EQUITY FUND) -
 Equity securities fluctuate in value as a result of various factors, which
are often unrelated to the value of the issuer of the securities. These
fluctuations may be pronounced. The Global Fund may invest in small market
capitalization companies and in equity securities that are considered by the
Advisor to be in their post-venture capital stage. These securities may have
limited marketability, and therefore, may be more volatile. Fluctuations in
the value of the Series' equity investments will affect the value of their
shares and thus the Funds' total returns to investors.
 
  FIXED INCOME SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND)
 - All fixed income securities are subject to two types of risks: credit risk
and interest rate risk. The credit risk relates to the ability of the issuer
to meet interest or principal payments or both as they come due. The interest
rate risk refers to the fluctuations in the net asset value of any portfolio
of fixed income securities resulting from the inverse relationship between the
price and yield of fixed income securities; that is, when the general level of
interest rates rises, the prices of outstanding fixed income securities
decline, and when interest rates fall, prices rise.
 
  FOREIGN SECURITIES AND CURRENCY CONSIDERATIONS (GLOBAL FUND, GLOBAL EQUITY
FUND, GLOBAL BOND FUND AND NON-U.S. EQUITY FUND) - Investments in securities
of foreign issuers may involve greater risks than those of U.S. issuers. There
is generally less information available to the public about non-U.S. companies
and less government regulation and supervision of non-U.S. stock exchanges,
brokers and listed companies. Non-U.S. companies are not subject to uniform
global accounting, auditing and financial reporting standards, practices and
requirements. Securities of some non-U.S. companies are less liquid and their
prices more volatile than securities of comparable U.S. companies. Securities
trading practices abroad may offer less protection to investors. Settlement of
transactions in some non-U.S. markets may be delayed or may be less frequent
than in the United States, which could affect the liquidity of the Series'
portfolios. Additionally, in some non-U.S. countries, there is the possibility
of expropriation or confiscatory taxation, limitations on the removal of
securities, property or other assets of the Series, political or social
instability, or diplomatic developments which could affect U.S. investments in
those countries. The Series intend to diversify broadly among countries, but
reserve the right to invest a substantial portion of their assets in one or
more countries if economic and business
 
                                      13

conditions warrant such investments. Brinson Partners will take these factors
into consideration in managing the Series' investments. Because the Series
will keep their books and records in U.S. dollars, the Series will be
required, for federal income tax purposes, to account for income and losses on
all transactions involving foreign currency under Section 988 of the Internal
Revenue Code of 1986, as amended, and the applicable U.S. Treasury
Regulations, so that generally any component of a gain or loss attributable to
currency fluctuations results in ordinary income or loss and not capital gain
or loss.
 
  The U.S. dollar market value of the Series' investments and of dividends and
interest earned by the Series may be significantly affected by changes in
currency exchange rates. Some currency prices may be volatile, and there is
the possibility of governmental controls on currency exchange or governmental
intervention in currency markets, which could adversely affect the Series.
Although the Series may attempt to manage currency exchange rate risks, there
is no assurance that the Series will do so at an appropriate time or that they
will be able to predict exchange rates accurately. For example, if the Series
increase their exposure to a currency and that currency's price subsequently
falls, such currency management may result in increased losses to the Series.
Similarly, if the Series decrease their exposure to a currency, and the
currency's price rises, the Series will lose the opportunity to participate in
the currency's appreciation. Each Series will manage currency exposures
relative to the normal currency allocation and will consider return and risk
of currency exposures relative to its respective Benchmark. In addition, if
the currency in which a security is denominated appreciates against the U.S.
dollar, the dollar value of the security will increase. Conversely, a decline
in the exchange rate of the currency would adversely affect the value of the
security expressed in dollars.
 
  On January 1, 1999, the European Monetary Union (the "EMU") plans to
introduce a new single currency, the Euro, which will replace the national
currencies of participating member nations. If the Series hold investments in
nations with currencies replaced by the Euro, the investment process,
including trading, foreign exchange, payments, settlements, cash accounts,
custody and accounting, will be impacted. Although it is not possible to
predict the impact of the Euro on the Series, the transition and the
elimination of currency risk among nations participating in the EMU may change
the economic environment and behavior of investors, particularly in European
markets.
 
  The adoption of the Euro does not reduce the currency risk presented by
fluctuations in value of the U.S. dollar to other currencies and, in fact,
currency exchange risk may be magnified. Also, increased market volatility may
result. Additional risks that may result include the fact that European
issuers in which the Series invest may face substantial conversion costs,
which may not be accurately anticipated and may impact issuer profitability
and creditworthiness.
 
  Brinson Partners has created an interdepartmental team to handle all Euro-
related changes to enable the Series to process transactions accurately and
completely with minimal disruption to business activities. While there can be
no assurance that the Series will not be adversely affected, Brinson Partners
and the Trust's service providers are taking steps that they believe are
reasonably designed to address the Euro issue.
 
  There are additional risks inherent in investing in less developed countries
which are applicable to the Global Fund. Compared to the United States and
other developed countries, emerging market countries may have relatively
unstable governments, economies based on only a few industries, and securities
markets that trade only a small number of securities and employ settlement
procedures different from those used in the United States. Prices on these
exchanges tend to be volatile and, in the past, securities in these countries
have offered greater potential for gain (as well as loss) than securities of
companies located in developed countries. Further, investments by foreign
investors are subject to a variety of restrictions in many emerging countries.
 
                                      14
<PAGE>
 
  Emerging markets countries such as those in which the Global Fund may invest
have historically experienced and may continue to experience, high rates of
inflation, high interest rates, exchange rate fluctuations or currency
depreciation, large amounts of external debt, balance of payments and trade
difficulties and extreme poverty and unemployment. Additional factors which
may influence the ability or willingness to service debt include, but are not
limited to, a country's cash flow situation, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of its debt
service burden to the economy as a whole, its government's policy towards the
International Monetary Fund, the World Bank and other international agencies
and the political constraints to which a government debtor may be subject.
 
  FOREIGN CURRENCY TRANSACTIONS (GLOBAL FUND, GLOBAL EQUITY FUND, GLOBAL BOND
FUND AND NON-U.S. EQUITY FUND) - To manage exposure to currency fluctuations,
the Series may alter fixed income or money market exposures, enter into
forward currency exchange contracts, buy or sell options or futures relating
to foreign currencies and may purchase securities indexed to currency baskets.
The Series will also use these currency exchange techniques in the normal
course of business to hedge against adverse changes in exchange rates in
connection with purchases and sales of securities. Some of these strategies
may require the Series to set aside liquid assets in a segregated custodial
account to cover their obligations.
 
  FUTURES, OPTIONS AND OTHER DERIVATIVE INSTRUMENTS (ALL SERIES) - The Series
may attempt to reduce the overall level of investment risk of particular
securities and attempt to protect against adverse market movements by
investing in futures, options and other derivative instruments. A derivative
instrument is commonly defined as a financial instrument whose performance and
value are derived, at least in part, from another source, such as the
performance of an underlying asset, a specific security or an index of
securities. The derivative instruments in which the Series may invest include
the purchase and writing of options on securities (including index options)
and options on foreign currencies, investing in futures contracts for the
purchase or sale of instruments based on financial indices, including interest
rate indices or indices of U.S. or foreign government securities, equity or
fixed income securities ("futures contracts"), forward contracts and swaps and
swap-related products such as equity index swaps, interest rate swaps,
currency swaps, and related caps, collars and floors.
 
  The investment in futures, options, forward contracts, swaps and similar
strategies by the Series will depend on Brinson Partners' judgment as to the
potential risks and rewards of different types of strategies, and it should be
recognized that the use of these instruments exposes the Series to additional
investment risks and transaction costs. If the Advisor incorrectly analyzes
the market conditions or does not employ the appropriate strategy with respect
to these instruments, the Series could be left in a less favorable position.
For example, gains and losses on investments in futures depend on the
Advisor's ability to predict correctly the direction of security prices,
interest rates and other economic factors. Additional risks inherent in the
use of futures, options and forward contracts include: adverse movements in
the prices of securities or currencies being hedged; the possible absence of a
liquid secondary market for any particular instrument at any time; and the
possible need to defer closing out certain hedge positions to avoid adverse
tax consequences. Options and futures can be volatile instruments and may not
perform as expected. A Series could experience losses if the prices of its
options and futures positions are poorly correlated with its other
investments. If a hedge is applied at an inappropriate time or price trends
are judged incorrectly, options and futures strategies may lower a Series'
return (i.e., options and futures may fail as hedging techniques in cases
where the price movements of the securities underlying the options and futures
do not follow the price movements of the portfolio securities subject to the
hedge). Options and futures traded on foreign exchanges generally are not
regulated by U.S. authorities and may offer less liquidity and less protection
to a Series in the event of default by the other party to the contract. The
loss from investing in futures transactions is potentially unlimited. A Series
does not intend to purchase put and call options that are traded on a national
stock exchange in an amount exceeding 5% of its net assets.

                                      15
<PAGE>
 
  Each Series may invest in derivatives for hedging purposes, to maintain
liquidity, or in anticipation of changes in the composition of its portfolio
holdings. No Series will engage in derivative investments purely for
speculative purposes. A Series will invest in one or more derivatives only to
the extent that the instrument under consideration is judged by the Advisor to
be consistent with the Series' overall investment objective and policies. In
making such judgment, the potential benefits and risks will be considered in
relation to the Series' other portfolio investments.
 
  Where not specified, investment limitations with respect to a Series'
derivative instruments will be consistent with that Series' existing
percentage limitations with respect to its overall investment policies and
restrictions. The risks and policies of various types of derivative
instruments permitted for the Series, including options, futures, forward
contracts and applicable interest rate swaps, are described in greater detail
in Appendix A in this Prospectus, and in the Statement of Additional
Information.
 
  NON-DIVERSIFIED STATUS (GLOBAL BOND FUND AND U.S. LARGE CAPITALIZATION
EQUITY FUND) - Each Series is classified as a "non-diversified" investment
company under the Act, which means that the proportion of the Series' assets
that may be invested in the securities of a single issuer is not limited by
the Act. Since each Series may invest a larger portion of its assets in the
securities of a single issuer than investment companies that are classified as
diversified funds under the Act, an investment in the Global Bond Fund or in
the U.S. Large Capitalization Equity Fund may be subject to greater
fluctuations in value than an investment in a diversified fund.
 
MANAGEMENT OF THE TRUST
 
THE BOARD OF TRUSTEES
 
  The Trust is a Delaware business trust. Under Delaware law, the Board of
Trustees has overall responsibility for managing the business and affairs of
the Trust. The Trustees, in turn, elect the officers of the Trust, who are
responsible for administering the day-to-day operations of the Series.
 
THE ADVISOR
 
  Brinson Partners, a Delaware corporation, is an investment management firm,
managing as of June 30, 1998, over $286 billion, primarily for pension and
profit sharing institutional accounts. Brinson Partners and its predecessor
entities have managed domestic and international investment assets since 1974
and global investment assets since 1982. Brinson Partners has offices in
Bahrain, Basel, Frankfurt, Geneva, Hong Kong, London, Melbourne, New York,
Paris, Rio de Janeiro, Singapore, Sydney, Tokyo and Zurich, in addition to its
principal office at 209 South LaSalle Street, Chicago, IL 60604-1295. Brinson
Partners is a part of the UBS Brinson Division of UBS AG. UBS AG, with
headquarters in Basel, Switzerland, is an internationally diversified
organization with operations in many aspects of the financial services
industry. UBS AG was formed by the merger of Union Bank of Switzerland and
Swiss Bank Corporation in June 1998.
 
  Brinson Partners also serves as the investment advisor to nine other
investment companies: Brinson Relationship Funds, which includes seventeen
investment portfolios (series); The Enterprise Group of Funds, Inc. -
International Growth Portfolio; Enterprise Accumulation Trust - International
Growth Portfolio; Fort Dearborn Income Securities, Inc.; The Hirtle Callaghan

  Pursuant to its investment advisory agreements (the "Agreements") with the
Trust on behalf of each Series, Brinson Partners receives a monthly fee at
various annual percentage rates of each Series' average daily net assets, as
described below, for providing investment advisory services. Brinson Partners
is responsible for paying its own expenses. Pursuant to the Agreements,
Brinson Partners is authorized, at its own expense, to obtain statistical and
other factual information and advice regarding economic factors and trends
from its foreign subsidiaries, but it does not generally receive advice or
recommendations regarding the purchase or sale of securities from such
subsidiaries.
 
  For providing investment advisory services during the fiscal year ended June
30, 1998, Brinson Partners was entitled to receive, under the Agreements, a
monthly fee at an annual rate as follows of the average daily net assets of
the Funds:
 
<TABLE>
      <S>                                                                  <C>
      Global Fund......................................................... 0.80%

      U.S. Bond Fund...................................................... 0.50
      Non-U.S. Equity Fund................................................ 0.80
</TABLE>
 
  The fee payable to Brinson Partners by the Global, Global Equity and Non-
U.S. Equity Funds is higher than the advisory fees paid by most other mutual
funds, but is comparable to those of other mutual funds with similar
investment objectives. The Advisor, however, has irrevocably agreed to waive
its fees and reimburse certain expenses so that the total operating expenses,
with the exception of 12b-1 expenses, of the UBS Investment Fund--Global, UBS
Investment Fund--Global Equity, UBS Investment Fund--Global Bond, UBS
Investment Fund--U.S. Balanced, UBS Investment Fund--U.S. Equity, UBS
Investment Fund--U.S. Large Capitalization Equity, UBS Investment Fund--U.S
Bond and UBS Investment Fund--Non-U.S. Equity will never exceed 1.10%, 1.00%,
0.90%, 0.80%, 0.80%, 0.80%, 0.60% and 1.00%, respectively.
 
PORTFOLIO MANAGEMENT
 
  Investment decisions for the Series are made by an investment management
team at Brinson Partners. No member of the investment management team is
primarily responsible for making recommendations for portfolio purchases.
 
ADMINISTRATION OF THE TRUST
 
THE UNDERWRITER
 
  Funds Distributor, Inc. ("FDI"), 60 State Street, Suite 1300, Boston, MA
02109, was engaged pursuant to an agreement dated February 5, 1997, for the
limited purpose of acting as underwriter to facilitate the filing of notices
regarding sales of the shares of the Trust under state securities laws and to
assist in the sale of shares. The fee for such service is borne by the
Advisor.

THE ADMINISTRATOR
 
ADMINISTRATIVE, ACCOUNTING, TRANSFER AGENCY AND CUSTODIAN SERVICES
 
  The Trust, on behalf of each Series, has entered into a Multiple Services
Agreement (the "Services Agreement") with Morgan Stanley Trust Company
("MSTC"), One Pierrepont Plaza, Brooklyn, New York 11201, pursuant to which
MSTC is required to provide general administrative, accounting, portfolio
valuation, transfer agency and custodian services to the Series, including the
coordination and monitoring of any third party service providers.
 
  MSTC provides custodian services for the securities and cash of the Series.
The custody fee schedule is based primarily on the net amount of assets held
during the period for which payment is being made.
 
  As authorized under the Services Agreement, MSTC has entered into a Mutual
Funds Service Agreement (the "CGFSC Agreement") with Chase Global Funds
Services Company ("CGFSC"), a corporate affiliate of The Chase Manhattan Bank,
under which CGFSC provides administrative, accounting, portfolio valuation and
transfer agency services to the Series. CGFSC's business address is 73 Tremont
Street, Boston, Massachusetts 02108-3913. Subject to the supervision of the
Board of Trustees of the Trust, MSTC supervises and monitors such services
provided by CGFSC.
 
  Pursuant to the CGFSC Agreement, CGFSC provides:
 
    (1) administrative services, including providing the necessary office
  space, equipment and personnel to perform administrative and clerical
  services; preparing, filing and distributing proxy materials, periodic
  reports to investors, registration statements and other documents; and
  responding to investor inquiries;
 
    (2) accounting and portfolio valuation services, including the daily
  calculation of each Fund's net asset value and the preparation of certain
  financial statements; and
 
    (3) transfer agency services, including the maintenance of each
  investor's account records, responding to investors' inquiries concerning
  accounts, processing purchases and redemptions of each Fund's shares,
  acting as dividend and distribution disbursing agent and performing other
  service functions. Shareholder inquiries should be made to the transfer
  agent at 1-800-794-7753.
 
  Also as authorized under the Services Agreement, MSTC has entered into a
sub-administration agreement (the "FDI Agreement") with FDI, under which FDI
provides administrative assistance to the Series with respect to (i)
regulatory matters, including regulatory developments and examinations, (ii)
all aspects of the Series' day-to-day operations, (iii) office facilities,
clerical and administrative services, and (iv) maintenance of books and
records.
 
  For its administrative, accounting, transfer agency and custodian services,
MSTC receives the following as compensation from the Trust on an annual basis:
0.0025% of the average daily U.S. assets of the Trust, 0.0525% of the average
daily non-U.S. assets of the Trust, 0.3250% of the average daily emerging
markets equity assets of the Trust; and 0.019% of the average daily emerging
markets debt assets of the Trust. MSTC receives an additional fee of 0.075% of
the average daily net assets of the Trust for administrative duties, the
latter subject to the expense limitation applicable to the Trust. No fee
(asset based or otherwise) is charged on any investments made by any fund into
any other fund sponsored or managed by the Advisor and assets of a fund that
are invested in another investment company or series thereof sponsored or
managed by the Advisor will not be counted in determining the 0.075%
administrative duties fee or the applicability of the expense limitation on
 
                                      18
<PAGE>
 
such fee. The foregoing fees include all out-of-pocket expenses or transaction
charges incurred by MSTC and any third party service provider in providing
such services. Pursuant to the CGFSC Agreement and the FDI Agreement, MSTC
pays CGFSC and FDI, respectively, for the services that CGFSC and FDI provide
to MSTC in fulfilling MSTC's obligations under the Services Agreement.
 
INDEPENDENT AUDITORS
 
  Ernst & Young LLP, Chicago, Illinois, are the independent auditors of the
Trust.
 
PURCHASE OF SHARES
 
  Shares of the Funds may be purchased directly from the Trust at the net
asset value next determined after receipt of the order in proper form by the
transfer agent. There is no sales load in connection with the purchase of Fund
shares. The Trust reserves the right to reject any purchase order and to
suspend the offering of shares of the UBS Investment Funds class of shares or
any Series. The Funds will not accept a check endorsed over by a third-party.
The minimum initial investment for Fund shares is $1,000 (including IRAs).
Subsequent investments for Fund shares will be accepted in minimum amounts of
$50 (including IRAs). The Trust reserves the right to vary the initial
investment minimum and minimums for additional investments in the Funds at any
time. In addition, Brinson Partners may waive the minimum initial investment
requirement for any investor.
   
  The UBS Investment Funds will be marketed directly through the offices of
UBS AG. Through its branches and subsidiaries, UBS AG conducts securities
research, provides investment advisory services and manages mutual funds in
major cities throughout the world, including Amsterdam, Basel, Frankfurt,
Geneva, Hong Kong, Houston, London, Los Angeles, Luxembourg, Miami, Monte
Carlo, New York, Paris, San Francisco, Singapore, Sydney, Tokyo, Toronto and
Zurich.     
 
  The UBS Investment Funds may be purchased through broker-dealers having
sales agreements with FDI, or through financial institutions having agency
agreements with FDI. There is no sales load or charge in connection with the
purchase of shares. The UBS Investment Funds class of shares, however, are
subject to annual 12b-1 Plan expenses of up to a maximum of 0.90% (0.25% of
which are service fees to be paid by the Funds to FDI, dealers or others for
providing personal service and/or maintaining shareholder accounts) of the
Funds' average daily net assets of such shares.
 
  Purchase orders for shares of the Funds which are received by the transfer
agent in proper form prior to the close of regular trading hours (currently
4:00 p.m. Eastern time) on the New York Stock Exchange (the "NYSE") on any day
that the Funds' net asset values per share are calculated, are priced
according to the net asset value determined on that day. Purchase orders for
shares of the Funds received after the close of the NYSE on a particular day
are priced as of the time the net asset value per share is next determined.
The Funds reserve the right to change the time at which purchases are priced
if the NYSE closes at a time other than 4:00 p.m. Eastern time or if an
emergency exists.
 
  Under certain circumstances, the Trust has entered into one or more
agreements (each, a "Sales Agreement") with brokers, dealers or financial
institutions (each, an "Authorized Dealer") under which the Authorized Dealer
may directly, or through intermediaries that the Authorized Dealer is
authorized to designate under the Sales Agreement (each, a "Sub-designee"),
accept purchase and redemption orders that are in "good form" on behalf of the
Funds. A Fund will be deemed to have received a purchase order when the
Authorized Dealer or Sub-designee accepts the purchase order and such order
will be priced at the Fund's net asset value next computed after such order is
accepted by the Authorized Dealer or Sub-designee.
 
                                      19
<PAGE>
 
  The Trust may accept telephone orders for Fund shares from broker-dealers or
service organizations which have been previously approved by the Trust. It is
the responsibility of such broker-dealers or service organizations to promptly
forward purchase orders and payments for the same to the Fund. Shares of the
Funds may be purchased through broker-dealers, banks and bank trust
departments which may charge the investor a transaction fee or other fee for
their services at the time of purchase. Such fees would not otherwise be
charged if the shares were purchased directly from the Trust.
 
  Brinson Partners, or its affiliates, from its own resources, may compensate
broker-dealers or other financial intermediaries ("Service Providers") for
marketing, shareholder servicing, recordkeeping and/or other services
performed with respect to UBS Investment Funds class of shares. Payments made
for any of these purposes may be made from its revenues, its profits or any
other sources available to it. When such service arrangements are in effect,
they are made generally available to all qualified Service Providers.

REDEMPTION OF SHARES
 
  Shares of the Funds may be redeemed without charge on any business day that
the NYSE is open. Redemptions will be effected at the net asset value per
share next determined after the receipt by the transfer agent of a redemption
request meeting the requirements described below. The Trust normally sends
redemption proceeds on the next business day but, in any event, redemption
proceeds are sent within five business days of receipt of a redemption request
in proper form. Payment also may be made by wire directly to any bank
previously designated by the shareholder in an Account Application. Please
note that the shareholder's bank may impose a fee for wire service. The Trust
will honor redemption requests of shareholders who recently purchased shares
by check, but will not mail the proceeds until it is reasonably satisfied that
the purchase check has cleared, which may take up to fifteen days from the
purchase date.
 
  Except as noted below, redemption requests received in proper form by the
transfer agent prior to the close of regular trading hours on the NYSE on any
business day that the Funds' net asset values per share are calculated are
effected that day. The Funds reserve the right to change the time at which
redemptions are priced if the NYSE closes at a time other than 4:00 p.m.
Eastern time or if an emergency exists. Redemption requests received in proper
form by the transfer agent after the close of the NYSE are effected as of the
time the net asset value per share is next determined. No redemption will be
processed until the transfer agent has received a completed application with
respect to the account.
 
  Shares of the Funds may be redeemed through certain broker-dealers, banks
and bank trust departments who may charge the investor a transaction fee or
other fee for their services at the time of redemption. Such fees would not
otherwise be charged if the shares were redeemed directly from the Trust.
 
  Under the Sales Agreement, the Authorized Dealer or Sub-designee is
authorized to accept redemption orders on behalf of the Funds. A Fund will be
deemed to have received a redemption order when the Authorized Dealer or Sub-
designee accepts the redemption order and such order will be priced at the
Fund's net asset value next computed after such order is accepted by the
Authorized Dealer or Sub-designee.
 
  The Trust will satisfy redemption requests in cash to the fullest extent
feasible, so long as such payments would not, in the opinion of Brinson
Partners or the Board of Trustees, result in the necessity of a Series selling
assets under disadvantageous conditions and to the detriment of the remaining
shareholders of the Series. Pursuant to the Trust's Agreement and Declaration
of Trust, payment for shares redeemed may be made either in cash or in-kind,
or partly in cash and partly in-kind. However, the Trust has elected, pursuant
to Rule 18f-1 under the Act, to redeem its shares solely in cash up to the
lesser of $250,000 or 1% of the net asset value of a Series, during any 90 day
period for any one shareholder. Payments in excess of this limit will also be
made wholly in cash unless the Board of Trustees believes that economic
conditions exist which would make such a practice detrimental to the best
interests of the Series. Any portfolio securities paid or distributed in-kind
would be valued as described under "Net Asset Value." In the event that an in-
kind distribution is made, a shareholder
 
                                      22
<PAGE>
 
may incur additional expenses, such as the payment of brokerage commissions,
on the sale or other disposition of the securities received from a Series. In-
kind payments need not constitute a cross-section of a Series' portfolio.
Where a shareholder has requested redemption of all or a part of the
shareholder's investment and where a Series computes such redemption in-kind,
the Series will not recognize gain or loss for federal tax purposes on the
securities used to compute the redemption, but the shareholder will recognize
gain or loss equal to the difference between the fair market value of the
securities received and the shareholder's basis in the Fund shares redeemed.
 
MINIMUM BALANCES
 
  Due to the relatively high cost of maintaining smaller accounts, the Trust
reserves the right to involuntarily redeem shares in any Fund account for
their then current net asset value (which will be promptly paid to the
shareholder) if at any time the total investment does not have a value of at
least $1,000 as a result of redemptions and not due to changes in the asset
value of the Series. The shareholder will be notified that the value of his or
her Fund account is less than the required minimum and will be allowed at
least 60 days to bring the value of the account up to the minimum before the
redemption is processed.
 
SHARES MAY BE REDEEMED IN ONE OF THE FOLLOWING WAYS:

NOTE: The Trust reserves the right to refuse a wire or telephone redemption if
     it is believed advisable to do so. Procedures for redeeming shares of the
     UBS Investment Funds by wire or telephone may be modified or terminated
     at any time by the Trust.

TELEPHONE TRANSACTIONS:
 
  Shareholders who wish to initiate purchase, exchange or redemption
transactions by telephone must elect the option, as described above. With
respect to such telephone transactions, the Funds will ensure that reasonable
procedures are used to confirm that instructions communicated by telephone are
genuine (including verification of the shareholder's social security number or
mother's maiden name) and, if they do not, the Funds or the transfer agent may
be liable for any losses due to unauthorized or fraudulent transactions.
Written confirmation will be provided for all purchase, exchange and
redemption transactions initiated by telephone.
 
EXCHANGE OF SHARES:
 
  Fund shares may be exchanged for UBS Investment Funds class of shares of any
other Series within the Trust. Exchanges will not be permitted between the UBS
Investment Funds class of shares and either the Brinson Fund-Class N shares or
the Brinson Fund-Class I shares of a Series of the Trust.
 
  Fund shares may be exchanged by written request or by telephone if the
shareholder has previously signed a telephone authorization on the Account
Application. The telephone exchange may be difficult to implement during times
of drastic economic or market changes. The Trust reserves the right to
restrict the frequency of, or otherwise modify, condition, terminate or impose
charges upon the exchange and/or telephone transfer privileges upon 60 days'
prior written notice to shareholders.
 
  Exchanges will be made on the basis of the relative net asset values per
share of the UBS Investment Funds class of shares of the Fund from which, and
the Fund into which, the exchange is made. Exchanges may be made only for
shares of a Series and class then offering its shares for sale in your state
of residence and are subject to the minimum initial investment requirement.
For federal income tax purposes, an exchange of shares would be treated as if
the shareholder had redeemed shares of one Series and reinvested in shares of
another Series. Gains or losses on the shares exchanged are realized by the
shareholder at the time of the exchange. Any shareholder wishing to make an
exchange should first obtain and review a prospectus of the other Series.
Requests for telephone exchanges must be received by the transfer agent by the
close of regular trading hours (currently 4:00 p.m. Eastern time) on the NYSE
on any day that the NYSE is open for regular trading. The Funds reserve the
right to change the time at which exchanges are priced if the NYSE closes at a
time other than 4:00 p.m. Eastern time or if an emergency exists.
 
TRANSFER OF SECURITIES:
 
  At the discretion of the Trust, investors may be permitted to purchase Fund
shares by transferring securities to a Series that meet the Series' investment
objective and policies. Securities transferred to a Series will be valued in
accordance with the same procedures used to determine the Fund's net asset
value at the time of the next determination of net asset value after such
acceptance. Shares issued by a Series in exchange for securities will be
issued at net asset value per share of the Fund determined as of the same
time. All dividends, interest, subscription, or other rights pertaining to
such securities shall become the property of the Series and must be delivered
to the Series by the investor upon receipt from the issuer. Investors who are
permitted to transfer such securities will be required to recognize a gain or
loss on such transfer and pay tax thereon, if applicable, measured by the
difference between the fair market value of the securities and the investors'
basis therein. Securities will not be accepted in exchange for shares of a
Fund unless: (1) such securities are, at the time of the exchange, eligible to
be included in the Series' portfolio and current market quotations are readily
available for such securities; (2) the investor represents and warrants that
all securities offered to be exchanged are not subject to any restrictions
upon their sale by the Series under the Securities Act of 1933, as amended, or
under the laws of the country in which the principal market for such
securities exists, or otherwise; and (3) the value of any such security
(except U.S. government securities) being exchanged, together with other
securities of the same issuer owned by the Series, will not exceed 5% of the
Series' net assets immediately after the transaction.
 
                                      24
<PAGE>
 
NET ASSET VALUE
 
  The net asset value per share for each class of shares of the Series is
computed by adding, with respect to each class of shares, the value of a
Series' investments, cash and other assets attributable to that class,
deducting liabilities of the class and dividing the result by the number of
shares of that class outstanding. The public offering price of the shares of
each classes' shares, all of which are sold on a continuous basis, is the net
asset value of that class. The valuation of assets for determining the net
asset value may be summarized as follows:
 
    Securities traded on securities exchanges are valued at the last
  available sale price. Securities that are not traded on a particular day or
  on an exchange are valued at either (a) the bid price or (b) a valuation
  within the range considered best to represent value in the circumstances.
  Price information on listed securities is generally taken from the closing
  price on the exchange where the security is primarily traded. Valuations of
  equity securities may be obtained from a pricing service and/or broker-
  dealers when such prices are believed to reflect fair value of such
  securities. Use of a pricing service and/or broker-dealers has been
  approved by the Board of Trustees. Futures contracts are valued at their
  daily quoted settlement price on the exchange on which they are traded.
  Forward foreign currency contracts are valued daily using the mean between
  the bid and asked forward points added to the current exchange rate and an
  unrealized gain or loss is recorded. The Series realizes a gain or loss
  upon settlement of the contracts. For valuation purposes, foreign
  securities initially expressed in foreign currency values will be converted
  into U.S. dollar values using WM/Reuters closing spot rates as of 4:00 p.m.
  London time.
 
    Securities with a remaining maturity of 60 days or less are valued at
  amortized cost, which approximates market value. Fixed income securities
  having a remaining maturity of over 60 days are valued at market price.
  Debt securities are valued on the basis of prices provided by a pricing
  service, or at the bid price where readily available, as long as the bid
  price, in the opinion of the Advisor, continues to reflect the value of the
  security. Redeemable securities issued by open-end investment companies are
  valued using their respective net asset values for purchase orders placed
  at the close of the NYSE. Securities (including over-the-counter options)
  for which market quotations are not readily available and other assets are
  valued at their fair value as determined in good faith by or under the
  direction of the Trustees.
 
  Net asset value is determined on each day that the NYSE is open, as of the
close of business of the regular session of the NYSE (currently 4:00 p.m.
Eastern time). Investments and requests to exchange or redeem shares received
by the Series in proper form before such close of business are effective, and
will receive the price determined, on that day. Investment, exchange and
redemption requests received after such close of business are effective, and
will receive the share price determined, on the next business day. The Funds
reserve the right to change the time at which purchases, redemptions and
exchanges are priced if the NYSE closes at a time other than 4:00 p.m. Eastern
time or if an emergency exists.
 
  Because of time zone differences, foreign exchanges and securities markets
will usually be closed prior to the time of the closing of the NYSE and values
of foreign futures and options and foreign securities will be determined as of
the earlier closing of such exchanges and securities markets. However, events
affecting the values of such foreign securities may occasionally occur between
the earlier closings of such exchanges and securities markets and the closing
of the NYSE which will not be reflected in the computation of the net asset
value of a class of a Series. If an event materially affecting the value of
such foreign securities occurs during such period, then such securities will
be valued at fair value as determined in good faith by or under the direction
of the Board of Trustees. Where a foreign securities market remains open at
the time that a Series values its portfolio securities, or closing prices of
securities from that market may not be retrieved because of local time
differences or other difficulties in obtaining such prices at that time, last
sale prices in such market at a point in time most practicable to timely
valuation of the Series may be used.
 
                                      25

  The Series' portfolio securities from time to time may be listed primarily
on foreign exchanges which trade on days when the NYSE is closed (such as
Saturday). As a result, the net asset value of a Fund may be significantly
affected by such trading on days when shareholders have no access to the Fund.
 
  All of the Series' classes of shares will bear pro rata all of the expenses
of that Series common to all classes. The net asset value of all outstanding
shares of each class of the Series will be computed on a pro rata basis for
each outstanding share based on the proportionate participation in the Series
represented by the value of shares of that class. All income earned and
expenses incurred by the Series will be borne on a pro rata basis by each
outstanding share of a class, based on each class' proportionate participation
in the Series represented by the value of shares of such class, except that
the Brinson Fund-Class N and the Brinson Fund-Class I will not incur any of
the expenses under the UBS Investment Funds class' 12b-1 Plan.
 
  Due to the specific distribution expenses and other costs that will be
allocable to each class, the dividends paid to each class, and related
performance, of the Series may vary. The per share net asset value of the UBS
Investment Funds class of shares and the Brinson Fund-Class N shares will
generally be lower than that of the Brinson Fund- Class I shares of a Series
because of the higher expenses borne by the UBS Investment Funds class of
shares and the Brinson Fund-Class N shares. It is expected, however, that the
net asset value per share of the two classes will tend to converge immediately
after the payment of dividends, which will differ by approximately the amount
of the service and distribution expense differential among the classes.
 
DISTRIBUTION PLAN
 
  The Board of Trustees of the Trust has adopted a distribution plan (the
"Plan") pursuant to Rule 12b-1 under the Act for the UBS Investment Funds
class of shares. The Plan permits each Series to reimburse FDI, Brinson
Partners and others from the assets of the UBS Investment Funds class of
shares a quarterly fee for services and expenses incurred in distributing and
promoting sales of the UBS Investment Fund class of shares. These expenses
include, but are not limited to, preparing and distributing advertisements and
sales literature, printing prospectuses and reports used for sales purposes,
and paying distribution and maintenance fees to brokers, dealers and others in
accordance with a selling agreement with the Trust on behalf of the UBS
Investment Funds class of shares or FDI. In addition, each Series may make
payments directly to FDI for payment to dealers or others, or directly to
others, such as banks, who assist in the distribution of the UBS Investment
Funds or provide services with respect to the UBS Investment Funds.
 
  UBS AG, or one of its affiliates, pursuant to a selected dealer agreement,
may provide additional compensation to securities dealers from its own
resources in connection with sales of the UBS Investment Funds class of shares
of the Series.
 
  The aggregate distribution fees paid by the Series from the assets of the
respective UBS Investment Funds class of shares to FDI and others under the
Plan may not exceed 0.90% of a Fund's average daily net assets in any year
(0.25% of which are service fees to be paid by the Series to FDI, dealers and
others, for providing personal service and/or maintaining shareholder
accounts). The Plan provides, however, that the aggregate distribution fees
for each respective Fund shall not exceed the following maximum amounts for
the 1999 fiscal year; UBS Investment Fund--Global--0.65%, UBS Investment
Fund--Global Equity--0.76%, UBS Investment Fund--Global Bond--0.49%, UBS
Investment Fund--U.S. Balanced--0.50%, UBS Investment Fund--U.S. Equity--
0.52%, UBS Investment Fund--U.S. Large Capitalization Equity--0.52%, UBS
Investment Fund--U.S. Bond--0.47% and UBS Investment Fund--Non-U.S. Equity--
0.84%.
 
                                      26
<PAGE>
 
  The Plan applies only to the UBS Investment Funds class of shares of each
Series. Shares of other classes are not included in calculating the Plan's
fees and the Plan is not used to assist in the distribution and marketing of
each Series' Brinson Fund-Class I or Brinson Fund-Class N shares. All payments
made by the UBS Investment Funds class of shares of a Series pursuant to the
Plan shall be made for the purpose of selling shares issued by the UBS
Investment Funds class of that Series. Distribution expenses which are
attributable to a particular class of a Series will be charged against the
assets of that class of that Series. Distribution expenses which are
attributable to more than one class or Series will be allocated among the
classes or Series, in proportion to their relative net assets.
 
  The quarterly fees paid to FDI under the Plan are subject to the review and
approval by the Trust's Trustees who are not "interested persons" of the
Advisor or FDI (as defined in the Act) and who may reduce the fees or
terminate the Plan at any time.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
 
DIVIDENDS
 
  The Series will distribute their net investment income semi-annually in June
and December. The Series will distribute annually in December substantially
all of their net long-term capital gains and any undistributed net short-term
capital gains realized during the one year period commencing November 1 (or
date of the creation of the Series, if later) and ending October 31, and, at
the same time, will distribute all of their net investment income earned
through the end of December and not previously distributed as ordinary (not
capital) income.
 
  Dividends and other distributions paid by a Series with respect to its UBS
Investment Fund class, Brinson Fund-Class N and Brinson Fund-Class I shares
are calculated in the same manner and at the same time. The per share amount
of any income dividends will generally differ among the classes only to the
extent that the Brinson Fund-Class N and the UBS Investment Fund class are
subject to separate 12b-1 fees. The per share dividends on UBS Investment
Funds class of shares and Brinson Fund-Class N shares will be lower than the
per share dividends on the Brinson Fund-Class I shares of each Series as a
result of the distribution and service fees applicable with respect to the UBS
Investment Funds class of shares and Brinson Fund-Class N shares.
 
  Income dividends and capital gain distributions are reinvested automatically
in additional Fund shares of the same class of a Series at net asset value,
unless the shareholder has notified the transfer agent, in writing, of the
shareholder's election to receive them in cash. Distribution options may be
changed at any time by requesting a change in writing. Any check in payment of
dividends or other distributions which cannot be delivered by the Post Office
or which remains uncashed for a period of more than one year may be reinvested
in the shareholder's account at the then current net asset value and the
dividend option may be changed from cash to reinvest. Dividends are reinvested
on the ex dividend date (the "ex date") at the net asset value determined at
the close of business on that date. Please note that shares purchased shortly
before the record date for a dividend or distribution may have the effect of
returning capital although such dividends and distributions are subject to
taxes.
 
TAXES
 
  Each Series has qualified, and intends to continue to qualify, for taxation
as a "regulated investment company" under the Internal Revenue Code of 1986,
as amended ("the Code"). Such qualification relieves a Series of liability for
federal income taxes to the extent the Series' earnings are distributed in
accordance with the Code. Each Series is treated as a separate corporate
entity for federal tax purposes.
 
                                      27
<PAGE>
 
  Distributions of any net investment income and of any net realized short-
term capital gains are taxable to shareholders as ordinary income. All
distributions may be subject to state and local taxes.
 
  Distributions of net capital gain (the excess of net long-term capital gain
over net short-term capital loss) are taxable to shareholders as long-term
capital gain regardless of how long a shareholder may have held shares of a
Series. The tax treatment of distributions of ordinary income or capital gains
will be the same whether the shareholder reinvests the distributions or elects
to receive them in cash. A distribution will be treated as paid on December 31
of the current calendar year if it is declared in October, November or
December with a record date in such a month and paid during January of the
following calendar year. Such distributions will be taxable to shareholders in
the calendar year in which the distributions are declared, rather than the
calendar year in which the distributions are received.
 
  Shareholders will be advised annually of the source and tax status of all
distributions for federal income tax purposes. Further information regarding
the tax consequences of investing in the Series is included in the Statement
of Additional Information. The above discussion is intended for general
information only. Investors should consult their own tax advisors for more
specific information on the tax consequences of particular types of
distributions.
 
  Redemptions of Series shares, and the exchange of shares between two Series
of the Trust, are taxable events and, accordingly, shareholders may realize
capital gains or losses on these transactions.
 
  Shareholders may be subject to back-up withholding on reportable dividend
and redemption payments ("back-up withholding") if a certified taxpayer
identification number is not on file with the Series, or if, to the Series'
knowledge, an incorrect number has been furnished, or if the Series has been
notified by the Internal Revenue Service that an account is subject to back-up
withholding. An individual's taxpayer identification number is the
individual's social security number.
 
  If more than 50% of a Series' total assets at the close of its taxable year
consists of stock or securities in foreign corporations, the Series may elect
to "pass-through" to shareholders for foreign tax credit purposes the amount
of foreign income taxes paid by the Series with respect to its direct holdings
of securities in foreign corporations. A Series will make such an election
only if it deems such election to be in the best interests of its
shareholders. If this election is made, shareholders of the Series will be
required to include in their gross incomes their pro rata share of foreign
taxes paid by the Series. However, shareholders will be able to treat their
pro rata share of foreign taxes as either a deduction (itemized deduction in
the case of individuals) or a foreign tax credit (but not both) against U.S.
income taxes on their tax returns. A Series which makes investments in the
securities of foreign corporations may make investments in foreign companies
that are "passive foreign investment companies" ("PFICs"). These investments
in PFICs may cause a Series to pay income taxes and interest charges. If
possible, the Series will not invest in PFICs or will adopt other strategies
to avoid these taxes and charges.
 
GENERAL INFORMATION
 
ORGANIZATION
 
  The Brinson Funds is a Delaware business trust organized pursuant to an
Agreement and Declaration of Trust, dated December 1, 1993. The Trust was
originally organized as a Maryland corporation on April 14, 1992.
 
                                      28
<PAGE>
 
On December 1, 1993, the Trust reorganized as a Delaware business trust
through a merger of the Maryland corporation into the Trust. The Trust is
registered under the Act as an open-end management investment company,
commonly known as a mutual fund and consists of eight different Series. The
Trustees of the Trust may establish additional series or classes of shares
without the approval of shareholders. All of the Series, except the Global
Bond Fund and the U.S. Large Capitalization Equity Fund, are diversified
portfolios. The assets of each Series belong only to that Series, and the
liabilities of each Series are borne solely by that Series and no other.
 
DESCRIPTION OF SHARES
 
  Each Series is authorized to issue an unlimited number of shares of
beneficial interest with a $0.001 par value per share. The Board of Trustees
has the power to designate one or more series or sub-series/classes of shares
of beneficial interest and to classify or reclassify only unissued shares with
respect to such series. Shares of each series represent equal proportionate
interests in the assets of that series only and have identical voting,
dividend, redemption, liquidation, and other rights, except that only shares
of each Series' Brinson Fund-Class N and UBS Investment Fund classes shall
have voting rights with respect to the Rule 12b-1 Plan relating to such
classes, respectively, as described below. All shares issued are fully paid
and non-assessable, and shareholders have no preemptive or other right to
subscribe to any additional shares and no conversion rights. Currently, the
Trust offers eight investment portfolios or series-Global Fund, Global Equity
Fund, Global Bond Fund, U.S. Balanced Fund, U.S. Equity Fund, U.S. Large
Capitalization Equity Fund, U.S. Bond Fund and Non-U.S. Equity Fund. Three
classes of shares are currently issued by the Trust for each Series, the
Brinson Fund-Class N, Brinson Fund-Class I, and the UBS Investment Funds
class. Prior to September 15, 1998, the "UBS Investment Funds class" was known
as the "Swisskey Fund class."
 
VOTING RIGHTS
 
  Each issued and outstanding full and fractional share of a Series is
entitled to one full and fractional vote in the Series and all shares of each
Series participate equally with regard to dividends, distributions, and
liquidations with respect to that Series. Shareholders do not have cumulative
voting rights. On any matter submitted to a vote of shareholders, shares of
each Series will vote separately except when a vote of shareholders in the
aggregate is required by law, or when the Trustees have determined that the
matter affects the interests of more than one Series, in which case the
shareholders of all such Series shall be entitled to vote thereon. Only the
UBS Investment Funds class shareholders may vote on matters related to the
Rule 12b-1 Plan associated with that class. Only the Brinson Fund-Class N
shareholders may vote on matters related to the Rule 12b-1 Plan associated
with that class.
 
  As of August 18, 1998, UBS AG held of record more than 25% of the
outstanding shares of the Global Fund; UBS held of record more than 25% of the
outstanding shares of the Global Equity Fund; UBS held of record more than 25%
of the outstanding shares of the Global Bond Fund; UBS held of record more
than 25% of the outstanding shares of the U.S. Balanced Fund; UBS SA held of
record more than 25% of the outstanding shares of the U.S. Equity Fund; Thomas
J. Digenan held of record more than 25% of the outstanding shares of the U.S.
Large Capitalization Equity Fund; UBS SA held of record more than 25% of the
outstanding shares of the U.S. Bond Fund; UBS and UBS SA each held of record
more than 25% of the outstanding shares of the Non-U.S. Equity Fund. A
shareholder that holds such a percentage of the outstanding shares of a class
may be deemed a controlling person of that class under the Act.
 
SHAREHOLDER MEETINGS
 
  The Trustees of the Trust do not intend to hold annual meetings of
shareholders of the Series. The U.S. Securities and Exchange Commission,
however, requires the Trustees to promptly call a meeting for the purpose
 
                                      29
<PAGE>
 
of voting upon the question of removal of any Trustee when requested to do so
by not less than 10% of the outstanding shareholders of the respective Series.
In addition, subject to certain conditions, shareholders of each Series may
apply to the Series to communicate with other shareholders to request a
shareholders' meeting to vote upon the removal of a Trustee or Trustees.
 
PORTFOLIO TURNOVER (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND AND U.S.
BOND FUND)
 
  As a result of the investment policies of the Global Fund, Global Bond Fund,
U.S. Balanced Fund and U.S. Bond Fund, their portfolio turnover rates may
exceed 100%. High portfolio turnover (over 100%) may involve correspondingly
greater brokerage commissions and other transaction costs, which will be borne
directly by the Series and ultimately by the Series' shareholders. In
addition, high portfolio turnover may result in increased short-term capital
gains, which, when distributed to shareholders, are treated as ordinary income
for tax purposes.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS
 
  The Trust will attempt to obtain the best overall price and most favorable
execution of transactions in portfolio securities. However, subject to
policies established by the Board of Trustees of the Trust, a Series may pay a
broker-dealer a commission for effecting a portfolio transaction for the
Series in excess of the amount of commission another broker-dealer would have
charged if Brinson Partners determines in good faith that the commission paid
was reasonable in relation to the brokerage or research services provided by
such broker-dealer, viewed in terms of that particular transaction or such
firm's overall responsibilities with respect to the clients, including the
Series, as to which it exercises investment discretion. In selecting and
monitoring broker-dealers and negotiating commissions, consideration will be
given to a broker-dealer's reliability, the quality of its execution services
on a continuing basis and its financial condition.
 
  When buying or selling securities, a Series may pay commissions to brokers
who are affiliated with the Advisor or the Series. The Series may purchase
securities in certain underwritten offerings for which an affiliate of the
Series or the Advisor may act as an underwriter. The Series may effect futures
transactions through, and pay commissions to, futures commission merchants who
are affiliated with the Advisor or the Series in accordance with procedures
adopted by the Board of Trustees of the Trust.
 
SHAREHOLDER REPORTS AND INQUIRIES
 
  Shareholders will receive semi-annual reports showing portfolio investments
and other information as of December 31 and annual reports audited by
independent auditors as of June 30. Shareholders with inquiries should call
the UBS Investment Funds at 1-800-794-7753 or write to The UBS Investment
Funds, P.O. Box 2798, Boston, MA 02708-2798.
 
YEAR 2000 ISSUES
 
  Like other investment companies, as well as other financial and business
organizations around the world, the Trust could be adversely affected if the
computer systems used by the Advisor, MSTC, CGFSC and other service providers,
in performing their administrative functions for the Trust, do not properly
process and calculate date-related information and data as of and after
January 1, 2000. This is commonly known as the "Year 2000 Issue." The Year
2000 Issue, and, in particular, foreign service providers' responsiveness to
the issue, could affect portfolio and operational areas including securities
trade processing, interest and dividend payments, securities pricing,
shareholder account services, custody functions and others. The Advisor, MSTC
and CGFSC are taking steps that they believe are reasonably designed to
address the Year 2000 Issue with respect to computer systems that they use and
to obtain reasonable assurances that comparable steps are being taken by
 
                                      30
<PAGE>
 
the Trust's other service providers. These include identifying those systems
that may not function properly after December 31, 1999, and correcting or
replacing those systems. In addition, steps include testing the processing of
Series data on all systems relied on by the Advisor, MSTC and CGFSC. As of the
date of this Prospectus, however, there can be no assurance that these steps
will be sufficient to avoid any adverse impact to the Series.
 
PERFORMANCE INFORMATION
 
  From time to time, performance information, such as yield or total return,
may be quoted in advertisements or in communications to present or prospective
shareholders. Performance quotations represent the Funds' past performance and
should not be considered as representative of future results. The current
yield will be calculated by dividing the net investment income earned per
share by a Fund during the period stated in the advertisement (based on the
average daily number of shares entitled to receive dividends outstanding
during the period) by the maximum net asset value per share on the last day of
the period and annualizing the result on a semi-annual compounded basis. The
Funds' total return may be calculated on an annualized and aggregate basis for
various periods (which periods will be stated in the advertisement). Average
annual return reflects the average percentage change per year in value of an
investment in a Fund. Aggregate total return reflects the total percentage
change over the stated period.
 
  To help investors better evaluate how an investment in the SwissKey Funds
might satisfy their investment objectives, advertisements regarding the Funds
may discuss yield or total return as reported by various financial
publications. Advertisements may also compare yield or total return to other
investments, indices and averages. The following publications, benchmarks,
indices and averages may be used: Lipper Mutual Fund Performance Analysis;
Lipper Fixed Income Analysis; Lipper Mutual Fund Indices; Morgan Stanley
Indices; Lehman Brothers Treasury Index; Salomon Brothers Indices; Dow Jones
Composite Average or its component indices; Standard & Poor's 500 Stock Index
or its component indices; Wilshire Indices; The New York Stock Exchange
composite or component indices; CDA Mutual Fund Report; Weisenberger-Mutual
Funds Panorama and Investment Companies; Mutual Fund Values and Mutual Fund
Service Book, published by Morningstar, Inc.; comparable portfolios managed by
the Advisor; and financial publications, such as Business Week, Kiplinger's
Personal Finance, Financial World, Forbes, Fortune, Money Magazine, The Wall
Street Journal, Barron's, et al., which rate fund performance over various
time periods.
 
  The principal value of an investment in the Funds will fluctuate, so that an
investor's shares, when redeemed, may be worth more or less than their
original cost. Any fees charged by banks or other institutional investors
directly to their customer accounts in connection with investments in shares
of the Funds will not be included in the UBS Investment Funds' calculations of
yield or total return. Further information about the performance of the Funds
is included in the Funds' Annual Report dated June 30, 1998, which may be
obtained without charge by contacting the Trust at 1-800-794-7753.

APPENDIX A
 
INVESTMENT POLICIES AND TECHNIQUES
 
  EQUITY SECURITIES (GLOBAL FUND, GLOBAL EQUITY FUND, U.S. BALANCED FUND, U.S.
EQUITY FUND, U.S. LARGE CAPITALIZATION EQUITY FUND AND NON-U.S. EQUITY FUND):
The Series may invest in a broad range of equity securities of U.S. and non-
U.S. issuers, including common stocks of companies or closed-end investment
companies, preferred stocks, debt securities convertible into or exchangeable
for common stock, securities such as warrants or rights that are convertible
into common stock and sponsored or unsponsored American, European and Global
depositary receipts ("Depositary Receipts"). The issuers of unsponsored
Depositary Receipts are not obligated to disclose material information in the
United States. The Series expect their U.S. equity investments to emphasize
large and intermediate capitalization companies, although the Global Fund may
also invest in small capitalization equity markets. The equity markets in the
non-U.S. component of the Series will typically include available shares of
larger capitalization companies. Capitalization levels are measured relative
to specific markets, thus large, intermediate and small capitalization ranges
vary country by country. The Global Fund may invest in equity securities of
companies considered by the Advisor to be in their post-venture capital stage,
or "post-venture capital companies." A post-venture capital company is a
company that has received venture capital financing either (a) during the
early stages of the company's existence or the early stages of the development
of a new product or service, or (b) as part of a restructuring or
recapitalization of the company. The Global Fund also may invest in open-end
investment companies advised by Brinson Partners, in equity securities of
issuers in emerging markets and in securities with respect to which the return
is derived from the equity securities of issuers in emerging markets.
 
  FIXED INCOME SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND): The Series may invest in a broad range of fixed income
securities of U.S. and non-U.S. issuers, including governments and
governmental entities, supranational issuers as well as corporations and other
business organizations. The Series may purchase U.S. dollar denominated
securities that reflect a broad range of investment maturities, qualities and
sectors. A majority of the fixed income securities in which the Series will
invest will possess a minimum rating of BBB- by S&P or Baa3 by Moody's or, if
unrated, will be determined to be of comparable quality by Brinson Partners.
Such securities are considered to be investment grade. While securities rated
BBB- or Baa3 are regarded as having an adequate capacity to pay principal and
interest, such bonds lack outstanding investment characteristics and, in fact,
have speculative characteristics; and changes in economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than is the case with higher rated bonds. Securities
rated lower than BBB- by S&P and Baa3 by Moody's are classified as non-
investment grade securities (commonly referred to as "junk bonds"), carry a
higher degree of risk and are considered to be speculative by the major credit
rating agencies. Each Series currently intends to limit its aggregate
investment in non-investment grade debt securities of its U.S. and non-U.S.
dollar denominated fixed income assets to no more than 5% of its net assets.
To the extent that a security held by a Series is downgraded to below
investment grade, the Series will dispose of that or another non-investment
grade security so that no more than 5% of its assets will be invested in below
investment grade securities. Other fixed income securities in which the Series
may invest include zero coupon securities, mortgage-backed securities, asset-
backed securities and when-issued securities.
 
  The non-U.S. fixed income component of the Series will typically be invested
in the securities of non-U.S. governments, governmental agencies and
supranational issues. A supranational entity is an entity established or
financially supported by the national governments of one or more countries to
promote reconstruction or development. Examples of supranational entities
include, among others: the World Bank, the European Economic Community, the
European Coal and Steel Community, the European Investment Bank, the Inter-
American Development Bank, the Export-Import Bank and the Asian Development
Bank.
 
                                      32
<PAGE>
 
  The Global Fund may invest in fixed income securities of emerging market
issuers, including government and government-related entities (including
participation in loans between governments and financial institutions), and of
entities organized to restructure outstanding debt securities of developing
countries' corporate issuers.
 
  CASH AND CASH EQUIVALENTS (ALL SERIES): The Series may invest a portion of
their assets in short-term debt securities (including repurchase agreements
and reverse repurchase agreements) of corporations, the U.S. government and
its agencies and instrumentalities and banks and finance companies, which may
be denominated in any currency. When unusual market conditions warrant, a
Series may make substantial temporary defensive investments in cash
equivalents up to a maximum of 100% of its net assets. Cash equivalent
holdings may be in any currency (although such holdings may not constitute
"cash or cash equivalents" for tax diversification purposes under the Code).
When a Series invests for defensive purposes, it may affect the attainment of
the Series' investment objective.
 
  Under the terms of an exemptive order issued by the SEC, each Series may
invest cash (i) held for temporary defensive purposes; (ii) not invested
pending investment in securities; (iii) that is set aside to cover an
obligation or commitment of the Series to purchase securities or other assets
at a later date; (iv) to be invested on a strategic management basis (i-iv is
herein referred to as "Uninvested Cash"); and (v) collateral that it receives
from the borrowers of its portfolio securities in connection with the Series'
securities lending program, in a series of shares of Brinson Supplementary
Trust (the "Supplementary Trust Series"). Brinson Supplementary Trust is a
private investment company which has retained the Advisor to manage its
investments. The Trustees of the Trust also serves as Trustees of the Brinson
Supplementary Trust. The Supplementary Trust Series will invest in U.S. dollar
denominated money market instruments having a dollar-weighted average maturity
of 90 days or less. A Series' investment of Uninvested Cash in shares of the
Supplementary Trust Series will not exceed 25% of the Series' total assets. In
the event that the Advisor waives 100% of its investment advisory fee with
respect to a Series, as calculated monthly, then that Series will be unable to
invest in the Supplementary Trust Series until additional investment advisory
fees are owed by the Series.
 
  ZERO COUPON SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND): Zero coupon securities are debt obligations which do not
entitle the holder to any periodic payments of interest prior to maturity or a
specified date when the securities begin paying current interest (the "cash
payment date") and, therefore, are issued and traded at a discount from their
value at maturity or par value. Such bonds carry an additional risk in that,
unlike bonds which pay interest throughout the period to maturity, a Series
investing in zero coupon securities will realize no cash until the cash
payment date and, if the issuer defaults, a Series may obtain no return at all
on its investment. The market price of zero coupon securities generally is
more volatile than the market price of securities that pay interest
periodically and are likely to be more responsive to changes in interest rates
than non-zero coupon securities having similar maturities and credit
qualities. For federal tax purposes, the Series will be required to include in
income daily portions of original issue discount accrued and to distribute the
same to shareholders annually, even if no payment is received before the
distribution date.
 
  MORTGAGE- AND ASSET-BACKED SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S.
BALANCED FUND AND U.S. BOND FUND): Mortgage-backed securities represent direct
or indirect participations in, or are secured by and payable from, pools of
mortgage loans secured by real property, and include single- and multi-class
pass-through securities and collateralized mortgage obligations. These
securities may be issued or guaranteed by agencies or instrumentalities of the
U.S. government. Other mortgage-backed securities are issued by private
issuers, generally originators of and investors in mortgage loans, including
savings associations, mortgage bankers, commercial banks, investment bankers
and special purpose entities (collectively, "private lenders").
 
                                      33
<PAGE>
 
Mortgage-backed securities issued by private lenders may be supported by pools
of mortgage loans or other mortgage-backed securities that are guaranteed,
directly or indirectly, by the U.S. government or one of its agencies or
instrumentalities, or they may be issued without any governmental guarantee of
the underlying mortgage assets but with some form of non-governmental credit
enhancement.
 
  Asset-backed securities have structural characteristics similar to mortgage-
backed securities. However, the underlying assets are not first-lien mortgage
loans or interests therein; rather, they include assets such as motor vehicle
installment sales contracts, other installment loan contracts, home equity
loans, leases of various types of property and receivables from credit card or
other revolving credit arrangements. Payments or distributions of principal
and interest on asset-backed securities may be supported by non-governmental
credit enhancements similar to those utilized in connection with mortgage-
backed securities.
 
  The yield characteristics of mortgage- and asset-backed securities differ
from those of traditional debt obligations. Among the principal differences
are that interest and principal payments are made more frequently on mortgage-
and asset-backed securities, usually monthly, and that principal may be
prepaid at any time because the underlying mortgage loans or other assets
generally may be prepaid at any time. As a result, the rate of return on these
securities may be affected by prepayments of principal on the underlying
loans, which generally increase as interest rates decline. As a result, if a
Series purchases these 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 a Series purchases these securities at a discount,
a prepayment rate that is faster than expected will increase yield to
maturity, while a prepayment rate that is slower than expected will reduce
yield to maturity. Accelerated prepayments on securities purchased by a Series
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 prepaid in full. In
addition, like other debt securities, the values of mortgage-related
securities, including government and government-related mortgage pools,
generally will fluctuate in response to market interest rates. The market for
privately issued mortgage- and asset-backed securities is smaller and less
liquid than the market for government sponsored mortgage-backed securities.
 
  WHEN-ISSUED SECURITIES (GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND): The Series may purchase securities on a "when-issued"
basis for payment and delivery at a later date. The price is generally fixed
on the date of commitment to purchase. During the period between purchase and
settlement, no interest accrues to a Series. At the time of settlement, the
market value of the security may be more or less than the purchase price. The
Series will establish a segregated account consisting of cash, U.S. government
securities, equity securities and/or investment and non-investment grade debt
securities in accordance with SEC positions. The cash, U.S. government
securities, equity securities, investment or non-investment grade debt
securities and other assets held in any segregated account maintained by the
Series with respect to any when-issued securities, options, futures, forward
contracts or other derivative transactions shall be liquid, unencumbered and
marked-to-market daily (the assets held in a segregated account are referred
to in this Prospectus as "Segregated Assets"), and such Segregated Assets
shall be maintained in accordance with pertinent positions of the SEC.
 
  FOREIGN CURRENCY TRANSACTIONS (GLOBAL FUND, GLOBAL EQUITY FUND, GLOBAL BOND
FUND AND NON-U.S. EQUITY FUND): The Series may conduct their foreign currency
exchange transactions on a spot (i.e., cash) basis at the spot rate prevailing
in the foreign currency exchange market or through entering into contracts to
purchase or sell foreign currencies at a future date (i.e., a "forward foreign
currency" contract or "forward" contract). A forward contract involves an
obligation to purchase or sell a specific currency amount 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
 
                                      34
<PAGE>
 
time of the contract. The Series will convert currency on a spot basis from
time to time and investors should be aware that changes in currency exchange
rates and exchange control regulations may affect the costs of currency
conversion.
 
  The Series may enter into forward contracts for hedging purposes as well as
non-hedging purposes. For hedging purposes, a Series may enter into contracts
to deliver or receive foreign currency it will receive from or require for its
normal investment activities. It may also use contracts in a manner intended
to protect foreign currency-denominated securities from declines in value due
to unfavorable exchange rate movements. A Series may also enter into contracts
with the intent of changing the relative exposure of the Series' portfolio of
securities to different currencies to take advantage of anticipated changes in
exchange rates.
 
  When a Series enters into forward contracts for non-hedging purposes, it
will establish a segregated account with its custodian bank in which it will
maintain Segregated Assets in accordance with SEC positions.
 
  At the maturity of a forward contract, a Series may either sell a portfolio
security and make delivery of the foreign currency, or it may retain the
security and terminate its contractual obligation to deliver the foreign
currency by purchasing an "offsetting" contract with the same currency trader,
obligating it to purchase, on the same maturity date, the same amount of the
foreign currency. A Series may realize a gain or loss from currency
transactions.
 
  OPTIONS ON CURRENCIES (GLOBAL FUND, GLOBAL EQUITY FUND, GLOBAL BOND FUND AND
NON-U.S. EQUITY FUND): The Series also may purchase and write put and call
options on foreign currencies (traded on U.S. and foreign exchanges or over-
the-counter markets) to manage the respective portfolio's exposure to changes
in currency exchange rates. Call options on foreign currency written by a
Series will be "covered," which means that the Series will own an equal amount
of, or an offsetting position in, the underlying foreign currency. With
respect to put options on foreign currency written by a Series, the Series
will establish a segregated account with its custodian bank consisting of
Segregated Assets in accordance with SEC positions.
 
  FUTURES CONTRACTS (ALL SERIES): The Series may enter into contracts for the
future purchase or sale of securities and indices. The Global Funds and the
Non-U.S. Equity Fund also may enter into contracts for the future purchase or
sale of foreign currencies. A financial futures contract is an agreement
between two parties to buy or sell a specified debt security at a set price on
a future date. An index futures contract is an agreement to take or make
delivery of an amount of cash based on the difference between the value of the
index at the beginning and at the end of the contract period. A futures
contract on a foreign currency is an agreement to buy or sell a specified
amount of a currency for a set price on a future date. A Series may enter into
a futures contract to the extent that not more than 5% of its assets are
required as futures contract margin deposits and its obligations relating to
such futures transactions represent not more than 25% of the Series' assets.
 
  The Global Fund, Global Equity Fund, Global Bond Fund and Non-U.S. Equity
Fund will enter into such futures transactions on domestic exchanges and, to
the extent such transactions have been approved by the Commodity Futures
Trading Commission for sale to customers in the United States, on foreign
exchanges.
 
  OPTIONS (ALL SERIES): The Series may purchase and write put and call options
on foreign or U.S. securities and indices and enter into related closing
transactions. A Series' may use options traded on U.S. exchanges and, to the
extent permitted by law, options traded over-the-counter and recognized
foreign exchanges. It is the position of the U.S. Securities and Exchange
Commission that over-the-counter options are illiquid. Accordingly, a Series
will invest in such options only to the extent consistent with its 15% limit
on investment in illiquid securities.
 
                                      35
<PAGE>
 
  REPURCHASE AGREEMENTS (ALL SERIES): The Series may enter into repurchase
agreements with banks or broker-dealers. Repurchase agreements are considered
under the Act to be collateralized loans by a Series to the seller secured by
the securities transferred to the Series. Repurchase agreements under the Act
will be fully collateralized by securities which the Series may invest in
directly. Such collateral will be marked-to-market daily. If the seller of the
underlying security under the repurchase agreement should default on its
obligation to repurchase the underlying security, the Series may experience
delay or difficulty in recovering its cash. To the extent that, in the
meantime, the value of the security purchased had decreased, the Series could
experience a loss. No more than 15% of a Series' net assets will be invested
in illiquid securities, including repurchase agreements which have a maturity
of longer than seven days. The Series must treat each repurchase agreement as
a security for tax diversification purposes and not as cash, a cash equivalent
or as a receivable.
 
  BORROWING (ALL SERIES): Each Series is authorized, within specified limits,
to borrow money as a temporary defensive measure for extraordinary purposes
and to pledge its assets in connection with such borrowings.
 
  LOANS OF PORTFOLIO SECURITIES (ALL SERIES): Each Series may loan its
portfolio securities to broker-dealers and other institutional investors
pursuant to agreements requiring that the loans be continuously secured by
collateral equal at all times in value to at least the market value of the
securities loaned. The major risk to which a Series would be exposed on a loan
transaction is the risk that the borrower would become bankrupt at a time when
the value of the security goes up. Therefore, a Series will only enter into
loan arrangements after a review of all pertinent factors by Brinson Partners,
subject to overall supervision by the Board of Trustees, including the
creditworthiness of the borrowing broker-dealer or institution and then only
if the consideration to be received from such loans would justify the risk.
Creditworthiness will be monitored on an ongoing basis by Brinson Partners.
 
  RULE 144A AND ILLIQUID SECURITIES (ALL SERIES): Each Series may invest up to
15% of its net assets in illiquid securities. Illiquid securities are those
securities that are not readily marketable, including restricted securities
and repurchase obligations that mature in more than seven days. Certain
restricted securities that may be resold to institutional investors pursuant
to Rule 144A under the Securities Act of 1933 may be determined to be liquid
under guidelines adopted by the Trust's Board of Trustees.
 
  INVESTMENT COMPANY SECURITIES (GLOBAL FUND): The Trust has received an
exemptive order (the "Exemptive Order") from the SEC which permits each Series
to invest its assets in certain portfolios of Brinson Relationship Funds,
another registered investment company advised by Brinson Partners. Currently,
only the Global Fund intends to invest in the portfolios of Brinson
Relationship Funds and only to the extent consistent with Brinson Partners'
investment process of allocating assets to specific asset classes. The Global
Fund will invest in the portfolios of Brinson Relationship Funds to obtain
exposure to the following asset classes: (1) equity and fixed income
securities of issuers located in emerging market countries ("Emerging Market
Securities"); (2) equity securities issued by companies with relatively small
overall market capitalizations ("Small Cap Securities"); and (3) high yield
securities ("High Yield Securities"). The Global Fund will invest in
corresponding portfolios of Brinson Relationship Funds only to the extent the
Advisor determines that such investments are a more efficient means for the
Global Fund to gain exposure to the asset classes identified above than by
investing directly in individual securities. Thus, to gain exposure to
Emerging Market Securities, the Global Fund will invest in the Brinson
Emerging Markets Equity Fund and the Brinson Emerging Markets Debt Fund
portfolios of Brinson Relationship Funds. To gain exposure to Small Cap
Securities and High Yield Securities, the Global Fund will invest in the
Brinson Post-Venture Fund and the Brinson High Yield Fund portfolios,
respectively, of Brinson Relationship Funds. Each portfolio of Brinson
Relationship Funds in which the Global Fund may invest is permitted to invest
in the same securities of a particular asset class in which the Global Fund is
permitted to invest directly, and with similar risks.

  RUSSIAN SECURITIES (GLOBAL FUND): The Series may invest in securities of
Russian companies. The registration, clearing and settlement of securities
transactions in Russia are subject to significant risks not normally
associated with securities transactions in the United States and other more
developed markets. Ownership of shares of Russian companies is evidenced by
entries in a company's share register (except where shares are held through
depositories that meet the requirements of the Act) and the issuance of
extracts from the register or, in certain limited cases, by formal share
certificates. However, Russian share registers are frequently unreliable and
the Series could possibly lose its registration through oversight, negligence
or fraud. Moreover, Russia lacks a centralized registry to record securities
transactions and registrars located throughout Russia or the companies
themselves maintain share registers. Registrars are under no obligation to
provide extracts to potential purchasers in a timely manner or at all and are
not necessarily subject to state supervision. In addition, while registrars
are liable under law for losses resulting from their errors, it may be
difficult for the Series to enforce any rights it may have against the
registrar or issuer of the securities in the event of loss of share
registration. Although Russian companies with more than 1,000 shareholders are
required by law to employ an independent company to maintain share registers,
in practice, such companies have not always followed this law. Because of this
lack of independence of registrars, management of a Russian company may be
able to exert considerable influence over who can purchase and sell the
company's shares by illegally instructing the registrar to refuse to record
transactions on the share register. Furthermore, these practices may prevent
the Series from investing in the securities of certain Russian companies
deemed suitable by the Advisor and could cause a delay in the sale of Russian
securities by the Fund if the company deems a purchaser unsuitable, which may
expose the Fund to potential loss on its investment.
 
  In light of the risks described above, the Board of Trustees of the Series
has approved certain procedures concerning the Series' investments in Russian
securities. Among these procedures is a requirement that the Series will not
invest in the securities of a Russian company unless that issuer's registrar
has entered into a contract with the Series' sub-custodian containing certain
protective conditions including, among other things, the sub-custodian's right
to conduct regular share confirmations on behalf of the Series. This
requirement will likely have the effect of precluding investments in certain
Russian companies that the Series would otherwise make.
 
  For more detailed descriptions of these investment policies and techniques,
please refer to the Statement of Additional Information, which is available
without charge upon request by calling 1-800-794-7753.

THE BRINSON FUNDS
        
    
The Brinson Funds (the "Trust"), 209 South LaSalle Street, Chicago, Illinois
60604-1295, is an open-end management investment company which currently offers
shares of eight series representing separate portfolios of investments: Global
Fund, Global Equity Fund, Global Bond Fund, U.S. Balanced Fund, U.S. Equity
Fund, U.S. Large Capitalization Equity Fund, U.S. Bond Fund and Non-U.S. Equity
Fund (collectively referred to as the "Series" or the "Funds," or individually
as a "Series" or a "Fund"). The Global Fund, Global Equity Fund and Global Bond
Fund are referred to herein collectively as the "Global Funds" or individually
as the "Global Fund" and the U.S. Balanced Fund, U.S. Equity Fund, U.S. Large
Capitalization Fund and U.S. Bond Fund are referred to herein as the "U.S.
Funds." The Trust currently offers three classes of shares for each Series: the
Brinson Fund-Class I, Brinson Fund-Class N and UBS Investment Funds class of
shares. The Brinson Fund-Class I shares of each Series, which are designed
primarily for institutional investors, have no sales charges and are not subject
to annual 12b-1 plan expenses. The Brinson Fund-Class N shares, which are
available exclusively to 401(k) participants, have no sales charges, but are
subject to annual 12b-1 plan expenses of 0.25% of average daily net assets of
the respective Series. The UBS Investment Funds class of shares of each Series
have no sales charges, but are subject to annual 12b-1 expenses of up to a
maximum of 0.90% of average daily net assets of the respective Series.     

INVESTMENT STRATEGIES

The following discussion of investment techniques and instruments supplements
and should be read in conjunction with the investment objectives and policies
set forth in the Prospectuses of the Funds.  The investment practices described
below, except for the discussion of percentage limitations with respect to
portfolio loan transactions and borrowing, are not fundamental and may be
changed by the Board of Trustees without the approval of the shareholders.

INVESTMENTS RELATING TO ALL FUNDS

The following discussion applies to all Series.

REPURCHASE AGREEMENTS
- ---------------------

When a Series enters into a repurchase agreement, it purchases securities from a
bank or broker-dealer which simultaneously agrees to repurchase the securities
at a mutually agreed upon time and price, thereby determining the yield during
the term of the agreement.  As a result, a repurchase agreement provides a fixed
rate of return insulated from market fluctuations during the term of the
agreement.  The term of a repurchase agreement generally is short, possibly
overnight or for a few days, although it may extend over a number of months (up
to one year) from the date of delivery.  Repurchase agreements will be fully
collateralized and the collateral will be marked-to-market daily.  A Series may
not enter into a repurchase agreement having more than seven days remaining to
maturity if, as a result, such agreement, together with any other illiquid
securities held by the Series, would exceed 15% of the value of the net assets
of the Series.

In the event of bankruptcy or other default by the seller of the security under
a repurchase agreement, a Series may suffer time delays and incur costs or
possible losses in connection with the disposition of the collateral.  In such
event, instead of the contractual fixed rate of return, the rate of return to a
Series would be dependent upon intervening fluctuations of the market value of
the underlying security and the accrued interest on the security.  Although a
Series would have rights against the seller for breach of contract with respect
to any losses arising from market fluctuations following the failure of the
seller to perform, the ability of a Series to recover damages from a seller in
bankruptcy or otherwise in default would be reduced.

Repurchase agreements are securities for purposes of the tax diversification
requirements that must be met for pass-through treatment under Subchapter M of
the Internal Revenue Code of 1986, as amended (the "Code").  Accordingly, each
Series will limit the value of its repurchase agreements on each of the
quarterly testing dates to ensure compliance with Subchapter M of the Code.

                                       4
<PAGE>
 
REVERSE REPURCHASE AGREEMENTS
- -----------------------------
    
Reverse repurchase agreements involve sales of portfolio securities of a Series
to member banks of the Federal Reserve System or securities dealers believed
creditworthy, concurrently with an agreement by the Series to repurchase the
same securities at a later date at a fixed price which is generally equal to the
original sales price plus interest. A Series retains record ownership and the
right to receive interest and principal payments on the portfolio securities
involved. In connection with each reverse repurchase transaction, a Series will
direct its custodian bank to place cash, U.S. government securities, equity
securities and/or investment and non-investment grade debt securities in a
segregated account of the Series in an amount equal to the repurchase price. Any
assets held in any segregated accounts maintained by a Series with respect to
any reverse repurchase agreements, when-issued securities, options, futures,
forward contracts or other derivative transactions shall be liquid, unencumbered
and marked-to-market daily (any such assets held in a segregated account are
referred to in this Statement of Additional Information as "Segregated Assets"),
and such Segregated Assets shall be maintained in accordance with pertinent
positions of the U.S. Securities and Exchange Commission (the "SEC").     

A reverse repurchase agreement involves the risk that the market value of the
securities retained by a Series may decline below the price of the securities
the Series has sold but is obligated to repurchase under the agreement.  In the
event the buyer of securities under a reverse repurchase agreement files for
bankruptcy or becomes insolvent, the Series' use of the proceeds of the
agreement may be restricted pending a determination by the other party, or its
trustee or receiver, whether to enforce the Series' obligation to repurchase the
securities.  Reverse repurchase agreements are considered borrowings by the
Series and as such, are subject to the same investment limitations.

BORROWING
- ---------
    
The Series may borrow money as a temporary measure for extraordinary purposes or
to facilitate redemptions. A Series will not borrow money in excess of 33 1/3%
of the value of its total assets. A Series has no intention of increasing its
net income through borrowing. Any borrowing will be done from a bank with the
required asset coverage of at least 300%. In the event that such asset coverage
shall at any time fall below 300%, a Series shall, within three days thereafter
(not including Sundays or holidays), or such longer period as the SEC may
prescribe by rules and regulations, reduce the amount of its borrowings to such
an extent that the asset coverage of such borrowings shall be at least 300%. A
Series will not pledge more than 10% of its net assets, or issue senior
securities as defined in the Investment Company Act of 1940, as amended (the
"Act"), except for notes to banks and reverse repurchase agreements. Investment
securities will not be purchased while a Series has an outstanding borrowing
that exceeds 5% of a Series' net assets.    

LOANS OF PORTFOLIO SECURITIES
- -----------------------------
    
The Series may lend portfolio securities to qualified broker-dealers and
financial institutions provided: (1) the loan is secured continuously by
collateral marked-to-market daily and maintained in an amount at least equal to
the current market value of the securities loaned; (2) a Series may call the
loan at any time and receive the securities loaned; (3) a Series 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 33 1/3% of the 
total assets of the Global Fund, Global Equity Fund, Global Bond Fund, U.S.
Balanced Fund, U.S. Equity Fund, U.S. Large Capitalization Equity Fund, U.S.
Bond Fund and Non-U.S. Equity Fund, respectively.      

Collateral will consist of U.S. and non-U.S. securities, cash equivalents or
irrevocable letters of credit.  Loans of securities involve a risk that the
borrower may fail to return the securities or may fail to maintain the proper
amount of collateral.  Therefore, a Series will only enter into portfolio loans
after a review of all pertinent  factors by Brinson Partners, Inc. ("Brinson
Partners" or the "Advisor") under the supervision of the Board of Trustees,
including the creditworthiness of the borrower.  Creditworthiness will be
monitored on an ongoing basis by the Advisor.

SWAPS
- -----
    
The Series (except for the Global Equity Fund, U.S. Equity Fund, U.S. Large
Capitalization Equity Fund and Non-U.S. Equity Fund) may engage in swaps,
including but not limited to interest rate, currency and index swaps and the
purchase or sale of related caps, floors, collars and other derivative
instruments. The Series expect to enter into these transactions primarily to
preserve a return or spread on a particular investment or portion of the
portfolio's duration, to protect against any increase in the price of securities
the Series anticipates purchasing at a later date, or to gain exposure to
certain markets in the most economical way possible.      

                                       5
<PAGE>
 
The use of swaps involves investment techniques and risks different from those
associated with ordinary portfolio security transactions. If Brinson Partners is
incorrect in its forecast of market values, interest rates and other applicable
factors, the investment performance of the Series will be less favorable than it
would have been if this investment technique was never used. Thus, if the other
party to a swap defaults, a Series' risk of loss consists of the net amount of
interest payments that the Series is contractually entitled to receive. Under
Internal Revenue Service rules, any lump sum payment received or due under the
notional principal contract must be amortized over the life of the contract.

FUTURES
- -------

The Series may enter into contracts for the purchase or sale for future delivery
of securities. The Global Funds and the Non-U.S. Equity Fund may also enter into
contracts for the purchase or sale for future delivery of foreign currencies.

A purchase of a futures contract means the acquisition of a contractual right to
obtain delivery to a Series of the securities or foreign currency called for by
the contract at a specified price during a specified future month. When a
futures contract is sold, a Series incurs a contractual obligation to deliver
the securities or foreign currency underlying the contract at a specified price
on a specified date during a specified future month. A Series may enter into
futures contracts and engage in options transactions related thereto to the
extent that not more than 5% of the Series' assets are required as futures
contract margin deposits and premiums on options, and may engage in such
transactions to the extent that obligations relating to such futures and related
options on futures transactions represent not more than 25% of a Series' assets.

When a Series enters into a futures transaction, it must deliver to the futures
commission merchant selected by a Series an amount referred to as "initial
margin." This amount is maintained by the futures commission merchant in a
segregated account at the custodian bank. Thereafter, a "variation margin" may
be paid by the Series to, or drawn by the Series from, such account in
accordance with controls set for such accounts, depending upon changes in the
price of the underlying securities subject to the futures contract.

The Series will enter into futures transactions on domestic exchanges and, to
the extent such transactions have been approved by the Commodity Futures Trading
Commission for sale to customers in the United States, on foreign exchanges. In
addition, all of the Series except the Global Bond Fund and U.S. Bond Fund may
sell stock index futures in anticipation of or during a market decline to
attempt to offset the decrease in market value of their common stocks that might
otherwise result; and they may purchase such contracts in order to offset
increases in the cost of common stocks that they intend to purchase. Unlike
other futures contracts, a stock index futures contract specifies that no
delivery of the actual stocks making up the index will take place. Instead,
settlement in cash must occur upon the termination of the contract.

While futures contracts provide for the delivery of securities, deliveries
usually do not occur. Contracts are generally terminated by entering into
offsetting transactions.

The Series may enter into futures contracts to protect against the adverse
affects of fluctuations in security prices, interest or foreign exchange rates
without actually buying or selling the securities or foreign currency. For
example, if interest rates are expected to increase, a Series might enter into
futures contracts for the sale of debt securities. Such a sale would have much
the same effect as selling an equivalent value of the debt securities owned by
the Series. If interest rates did increase, the value of the debt securities in
the portfolio would decline, but the value of the futures contracts to the
Series would increase at approximately the same rate, thereby keeping the net
asset value of the Series from declining as much as it otherwise would have.
Similarly, when it is expected that interest rates may decline, futures
contracts may be purchased to hedge in anticipation of subsequent purchases of
securities at higher prices. Since the fluctuations in the value of futures
contracts should be similar to those of debt securities, the Series could take
advantage of the anticipated rise in value of debt securities without actually
buying them until the market had stabilized. At that time, the futures contracts
could be liquidated and the Series could then buy debt securities on the cash
market.

To the extent that market prices move in an unexpected direction, a Series may
not achieve the anticipated benefits of futures contracts or may realize a loss.
For example, if a Series is hedged against the possibility of an increase in
interest rates which would adversely affect the price of securities held in its
portfolio and interest rates decrease instead, the Series would lose part or all
of the benefit of the increased value which it has because it would have
offsetting losses

                                       6
<PAGE>
 
in its futures position. In addition, in such situations, if the Series had
insufficient cash, it may be required to sell securities from its portfolio to
meet daily variation margin requirements. Such sales of securities may, but will
not necessarily, be at increased prices which reflect the rising market. A
Series may be required to sell securities at a time when it may be
disadvantageous to do so.

OPTIONS
- -------

The Series may purchase and write call or put options on securities but will
only engage in option strategies for non-speculative purposes.

The U.S. Funds may invest in options that are listed on U.S. exchanges or traded
over-the-counter and the Global Funds and the Non-U.S. Equity Fund may invest in
options that are either listed on U.S. or recognized foreign exchanges or traded
over-the-counter. Certain over-the-counter options may be illiquid. Thus, it may
not be possible to close options positions and this may have an adverse impact
on a Series' ability to effectively hedge its securities. The Series have been
notified by the SEC that it considers over-the-counter options to be illiquid.
Accordingly, a Series will only invest in such options to the extent consistent
with its 15% limit on investments in illiquid securities.

PURCHASING CALL OPTIONS - The Series may purchase call options on securities to
the extent that premiums paid by a Series do not aggregate more than 20% of the
Series' total assets. When a Series purchases a call option, in return for a
premium paid by the Series to the writer of the option, the Series obtains the
right to buy the security underlying the option at a specified exercise price at
any time during the term of the option. The writer of the call option, who
receives the premium upon writing the option, has the obligation, upon exercise
of the option, to deliver the underlying security against payment of the
exercise price. The advantage of purchasing call options is that a Series may
alter portfolio characteristics and modify portfolio maturities without
incurring the cost associated with transactions.

A Series may, following the purchase of a call option, liquidate its position by
effecting a closing sale transaction. This is accomplished by selling an option
of the same series as the option previously purchased. The Series will realize a
profit from a closing sale transaction if the price received on the transaction
is more than the premium paid to purchase the original call option; the Series
will realize a loss from a closing sale transaction if the price received on the
transaction is less than the premium paid to purchase the original call option.

Although the Series will generally purchase only those call options for which
there appears to be an active secondary market, there is no assurance that a
liquid secondary market on an exchange will exist for any particular option, or
at any particular time, and for some options no secondary market on an exchange
may exist. In such event, it may not be possible to effect closing transactions
in particular options, with the result that a Series would have to exercise its
options in order to realize any profit and would incur brokerage commissions
upon the exercise of such options and upon the subsequent disposition of the
underlying securities acquired through the exercise of such options. Further,
unless the price of the underlying security changes sufficiently, a call option
purchased by a Series may expire without any value to the Series, in which event
the Series would realize a capital loss which will be short-term unless the
option was held for more than one year.

COVERED CALL WRITING - A Series may write covered call options from time to time
on such portions of its portfolio, without limit, as Brinson Partners determines
is appropriate in seeking to achieve the Series' investment objective. The
advantage to a Series of writing covered calls is that the Series receives a
premium which is additional income. However, if the security rises in value, the
Series may not fully participate in the market appreciation.
    
During the option period for a covered call option, the writer may be assigned
an exercise notice by the broker-dealer through whom such call option was sold,
requiring the writer to deliver the underlying security against payment of the
exercise price. This obligation is terminated upon the expiration of the option
or upon entering a closing purchase transaction. A closing purchase transaction,
in which a Series, as writer of an option, terminates its obligation by
purchasing an option of the same series as the option previously written, cannot
be effected with respect to an option once the option writer has received an
exercise notice for such option.

Closing purchase transactions will ordinarily be effected to realize a profit on
an outstanding call option, to prevent an underlying security from being called,
to permit the sale of the underlying security or to enable a Series to write
another

                                       7
<PAGE>
 
call option on the underlying security with either a different exercise price or
expiration date or both. A Series may realize a net gain or loss from a closing
purchase transaction depending upon whether the net amount of the original
premium received on the call option is more or less than the cost of effecting
the closing purchase transaction. Any loss incurred in a closing purchase
transaction may be partially or entirely offset by the premium received from a
sale of a different call option on the same underlying security. Such a loss may
also be wholly or partially offset by unrealized appreciation in the market
value of the underlying security. Conversely, a gain resulting from a closing
purchase transaction could be offset in whole or in part by a decline in the
market value of the underlying security.

If a call option expires unexercised, the Series will realize a short-term
capital gain in the amount of the premium on the option less the commission
paid. Such a gain, however, may be offset by depreciation in the market value of
the underlying security during the option period. If a call option is exercised,
a Series will realize a gain or loss from the sale of the underlying security
equal to the difference between the cost of the underlying security and the
proceeds of the sale of the security plus the amount of the premium on the
option less the commission paid.

The Series will write call options only on a covered basis, which means that a
Series will own the underlying security subject to a call option at all times
during the option period. Unless a closing purchase transaction is effected, a
Series would be required to continue to hold a security which it might otherwise
wish to sell or deliver a security it would want to hold. The exercise price of
a call option may be below, equal to or above the current market value of the
underlying security at the time the option is written.

PURCHASING PUT OPTIONS - The Series may only purchase put options to the extent
that the premiums on all outstanding put options do not exceed 20% of a Series'
total assets. A Series will, at all times during which it holds a put option,
own the security covered by such option. With regard to the writing of put
options, each Series will limit the aggregate value of the obligations
underlying such put options to 50% of its total net assets. The purchase of the
put on substantially identical securities held will constitute a short sale for
tax purposes, the effect of which is to create short-term capital gain on the
sale of the security and to suspend running of its holding period (and treat it
as commencing on the date of the closing of the short sale) or that of a
security acquired to cover the same if, at the time the put was acquired, the
security had not been held for more than one year.

A put option purchased by a Series gives it the right to sell one of its
securities for an agreed price up to an agreed date. The Series intend to
purchase put options in order to protect against a decline in the market value
of the underlying security below the exercise price less the premium paid for
the option ("protective puts"). The ability to purchase put options will allow
the Series to protect unrealized gains in an appreciated security in their
portfolios without actually selling the security. If the security does not drop
in value, a Series will lose the value of the premium paid. A Series may sell a
put option which it has previously purchased prior to the sale of the securities
underlying such option. Such sale will result in a net gain or loss depending on
whether the amount received on the sale is more or less than the premium and
other transaction costs paid on the put option which is sold.

The Series may sell a put option purchased on individual portfolio securities.
Additionally, the Series may enter into closing sale transactions. A closing
sale transaction is one in which a Series, when it is the holder of an
outstanding option, liquidates its position by selling an option of the same
series as the option previously purchased.

WRITING PUT OPTIONS - The Series may also write put options on a secured basis
which means that a Series will maintain in a segregated account with its
custodian Segregated Assets in an amount not less than the exercise price of the
option at all times during the option period. The amount of Segregated Assets
held in the segregated account will be adjusted on a daily basis to reflect
changes in the market value of the securities covered by the put option written
by the Series. Secured put options will generally be written in circumstances
where Brinson Partners wishes to purchase the underlying security for a Series'
portfolio at a price lower than the current market price of the security. In
such event, a Series would write a secured put option at an exercise price
which, reduced by the premium received on the option, reflects the lower price
it is willing to pay.

                                       8
<PAGE>
 
Following the writing of a put option, a Series may wish to terminate the
obligation to buy the security underlying the option by effecting a closing
purchase transaction. This is accomplished by buying an option of the same
series as the option previously written. The Series may not, however, effect
such a closing transaction after it has been notified of the exercise of the
option.

    
INDEX OPTIONS

The Series may purchase exchange-listed call options on stock and
fixed income indices depending upon whether a Series is an equity or bond series
and sell such options in closing sale transactions for hedging purposes. A
Series may purchase call options on broad market indices to temporarily achieve
market exposure when the Series is not fully invested. A Series may also
purchase exchange-listed call options on particular market segment indices to
achieve temporary exposure to a specific industry.     

In addition, the Series may purchase put options on stock and fixed income
indices and sell such options in closing sale transactions for hedging purposes.
A Series may purchase put options on broad market indices in order to protect
its fully invested portfolio from a general market decline. Put options on
market segments may be bought to protect a Series from a decline in value of
heavily weighted industries in the Series' portfolio. Put options on stock and
fixed income indices may also be used to protect a Series' investments in the
case of a major redemption.

The Series may also write (sell) put and call options on stock and fixed income
indices. While the option is open, a Series will maintain a segregated account
with its custodian in an amount equal to the market value of the option.

Options on indices are similar to regular options except that an option on an
index gives the holder the right, upon exercise, to receive an amount of cash if
the closing level of the index upon which the option is based is greater than
(in the case of a call) or lesser than (in the case of a put) the exercise price
of the option. This amount of cash is equal to the difference between the
closing price of the index and the exercise price of the option expressed in
dollars times a specified multiple (the "multiplier"). The indices on which
options are traded include both U.S. and non-U.S. markets.

SPECIAL RISKS OF OPTIONS ON INDICES
- -----------------------------------

The Series' purchases of options on indices will subject them to the risks
described below.

Because the value of an index option depends upon movements in the level of the
index rather than the price of a particular security, whether a Series will
realize gain or loss on the purchase of an option on an index depends upon
movements in the level of prices in the market generally or in an industry or
market segment rather than movements in the price of a particular security.
Accordingly, successful use by a Series of options on indices is subject to
Brinson Partners' ability to predict correctly the direction of movements in the
market generally or in a particular industry. This requires different skills and
techniques than predicting changes in the prices of individual securities.

Index prices may be distorted if trading of a substantial number of securities
included in the index is interrupted causing the trading of options on that
index to be halted. If a trading halt occurred, a Series would not be able to
close out options which it had purchased and the Series may incur losses if the
underlying index moved adversely before trading resumed. If a trading halt
occurred and restrictions prohibiting the exercise of options were imposed
through the close of trading on the last day before expiration, exercises on
that day would be settled on the basis of a closing index value that may not
reflect current price information for securities representing a substantial
portion of the value of the index.

If a Series holds an index option and exercises it before final determination of
the closing index value for that day, it runs the risk that the level of the
underlying index may change before closing. If such a change causes the
exercised option to fall "out-of-the-money," the Series will be required to pay
the difference between the closing index value and the exercise price of the
option (times the applicable multiplier) to the assigned writer. Although a
Series may be able to minimize this risk by withholding exercise instructions
until just before the daily cutoff time or by selling rather than exercising the
option when the index level is close to the exercise price, it may not be
possible to eliminate this risk entirely because the cutoff times for index
options may be earlier than those fixed for other types of options and may occur
before definitive closing index values are announced.

RULE 144A SECURITIES
- --------------------

    
The Series may invest in securities that are exempt under Rule 144A from the
registration requirements of the Securities Act of 1933, as amended (the "1933
Act"). Those securities purchased under Rule 144A are traded among qualified
institutional investors.

The Board of Trustees of the Trust has instructed Brinson Partners to consider
the following factors in determining the liquidity of a security purchased under
Rule 144A: (i) the frequency of trades and trading volume for the security; (ii)
whether at least three dealers are willing to purchase or sell the security and
the number of potential purchasers; (iii) whether at least two dealers are
making a market in the security; and (iv) the nature of the security and the
nature of the marketplace trades (e.g., the time needed to dispose of the
security, the method of soliciting offers and the mechanics of transfer).
Although having delegated the day-to-day functions, the Board of Trustees will
continue to monitor and periodically review the Advisor's selection of Rule 144A
securities, as well as the Advisor's determinations as to their liquidity.
Investing in securities under Rule 144A could have the effect of increasing the
level of a Series' illiquidity to the extent that qualified institutional buyers
become, for a time, uninterested in purchasing these securities. After the
purchase of a security under Rule 144A, however, the Board of Trustees and
Brinson Partners will continue to monitor the liquidity of that security to
ensure that each Series has no more than 15% of its total assets in illiquid
securities.

    
The Series will limit investments in securities of issuers which the Series are
restricted from selling to the public without registration under the 1933 Act to
no more than 15% of the Series' total assets, excluding restricted securities
eligible for resale pursuant to Rule 144A that have been determined to be liquid
pursuant a policy and procedures adopted by the Trust's Board of Trustees which
includes continuing oversight by the Board of Trustees.

If Brinson Partners determines that a security purchased in reliance on Rule
144A which was previously determined to be liquid, is no longer liquid and, as a
result, the Series' holdings of illiquid securities exceed the Series' 15% limit
on investment in such securities, Brinson Partners will determine what action
shall be taken to ensure that the Series continue to adhere to such limitation,
including disposing of illiquid assets which may include such Rule 144A
securities.

OTHER INVESTMENTS
- -----------------

The Board of Trustees may, in the future, authorize a Series to invest in
securities other than those listed in this Statement of Additional Information
and in the Prospectuses, provided such investment would be consistent with that
Series' investment objective and that it would not violate any fundamental
investment policies or restrictions applicable to that Series.

INVESTMENTS RELATING TO THE GLOBAL FUNDS AND THE NON-U.S. EQUITY FUND

The following discussion of strategies, techniques and policies applies only to
the Global Fund, Global Equity Fund, Global Bond Fund and the Non-U.S. Equity
Fund.

FOREIGN SECURITIES
- ------------------

Investors should recognize that investing in foreign issuers involves certain
considerations, including those set forth in the Series' Prospectuses, which are
not typically associated with investing in U.S. issuers. Since the stocks of
foreign companies are frequently denominated in foreign currencies, and since
the Series may temporarily hold uninvested reserves in bank deposits in foreign
currencies, the Series will be affected favorably or unfavorably by changes in
currency rates and in exchange control regulations and may incur costs in
connection with conversions between various currencies. The investment policies
of the Series permit them to enter into forward foreign currency exchange
contracts, futures, options and interest rate swaps (in the case of the Global
Funds) in order to hedge portfolio holdings and commitments against changes in
the level of future currency rates.

There has been in the past, and there may be again in the future, an interest
equalization tax levied by the United States in connection with the purchase of
foreign securities such as those purchased by the Series. Payment of an interest
equalization tax, if imposed, would reduce the Series' rates of return on
investment. Dividends paid by foreign issuers may be subject to withholding and
other foreign taxes which may decrease the net return on such investments as
compared to dividends paid to the Series by U.S. corporations. The Series'
ability to "pass through" the foreign taxes paid for tax credit or deduction
purposes will be determined by the composition of the Series' portfolios. More
than 50%

                                       10
<PAGE>
 
     
of a Series must be invested in stock or securities of foreign corporations for
"pass through" to be possible in the first instance. Special rules govern the
federal income tax treatment of certain transactions denominated in terms of a
currency other than the U.S. dollar or determined by reference to the value of
one or more currencies other than the U.S. dollar. The types of transactions
covered by the special rules generally include the following: (i) the
acquisition of, or becoming the obligor under, a bond or other debt instrument
(including, to the extent provided in the Treasury Regulations, preferred
stock); (ii) the accruing of certain trade receivables and payables; and (iii)
the entering into or acquisition of any forward contract, futures contract and
similar financial instruments other than any "regulated futures contract" or
"non-equity option" which would be marked-to-market under the rules of Section
1256 of the Code if held at the end of the tax year. The disposition of a
currency other than the U.S. dollar by a U.S. taxpayer is also treated as a
transaction subject to the special currency rules. However, foreign currency-
related regulated futures contracts and non-equity options are generally not
subject to these special currency rules. If subject, they are or would be
treated as sold for their fair market value at year-end under the marked-to-
market rules applicable to other futures contracts, unless an election is made
to have such currency rules apply. With respect to transactions covered by the
special rules, foreign currency gain or loss is calculated separately from any
gain or loss on the underlying transaction and is normally a taxable gain or
loss. A taxpayer may elect to treat as capital gain or loss foreign currency
gain or loss arising from certain identified forward contracts, futures
contracts and options that are capital assets in the hands of the taxpayer and
which are not part of a straddle. Certain transactions subject to the special
currency rules that are part of a "section 988 hedging transaction" (as defined
in the Code and the Treasury Regulations) will be integrated and treated as a
single transaction or otherwise treated consistently for purposes of the Code.
The income tax effects of integrating and treating a transaction as a single
transaction are generally to create a synthetic debt instrument that is subject
to the original discount provisions. It is anticipated that some of the non-U.S.
dollar denominated investments and foreign currency contracts the Series may
make or enter into will be subject to the special currency rules described
above.

FORWARD FOREIGN CURRENCY CONTRACTS
- ----------------------------------

The Series may purchase or sell currencies and/or engage in forward foreign
currency transactions in order to expedite settlement of portfolio transactions
and to manage currency risk.

Forward foreign currency contracts are traded in the inter-bank market conducted
directly between currency traders (usually large commercial banks) and their
customers. A forward contract generally has no deposit requirement and no
commissions are charged at any stage for trades. The Series will account for
forward contracts by marking-to-market each day at current forward contract
values.

A Series will only enter into forward contracts to sell, for a fixed amount of
U.S. dollars or other appropriate currency, an amount of foreign currency, to
the extent that the value of the short forward contract is covered by the
underlying value of securities denominated in the currency being sold.
Alternatively, when a Series enters into a forward contract to sell an amount of
foreign currency, the Series' custodian or sub-custodian will place Segregated
Assets in a segregated account of the Series in an amount not less than the
value of the Series' total assets committed to the consummation of such forward
contracts. If the additional Segregated Assets placed in the segregated account
decline, additional cash or securities will be placed in the account on a daily
basis so that the value of the account will equal the amount of the Series'
commitments with respect to such contracts.

OPTIONS ON FOREIGN CURRENCIES
- -----------------------------

The Series also may purchase and write put and call options on foreign
currencies (traded on U.S. and foreign exchanges or over-the-counter markets) to
manage the Series' exposure to changes in currency exchange rates. The Series
may purchase and write options on foreign currencies for hedging purposes in a
manner similar to that in which futures contracts on foreign currencies, or
forward contracts, will be utilized. For example, a decline in the dollar value
of a foreign currency in which portfolio securities are denominated will reduce
the dollar value of such securities, even if their value in the foreign currency
remains constant. In order to protect against such diminutions in the value of
portfolio securities, the Series may purchase put options on the foreign
currency. If the dollar price of the currency does decline, a Series will have
the right to sell such currency for a fixed amount in dollars and will thereby
offset, in whole or in part, the adverse effect on its portfolio which otherwise
would have resulted.

Conversely, where a rise in the dollar value of a currency in which securities
to be acquired are denominated is projected, thereby increasing the dollar price
of such securities, the Series may purchase call options on such currency.

                                       11
<PAGE>
 
The purchase of such options could offset, at least partially, the effects of
the adverse movement in exchange rates. As in the case of other types of
options, however, the benefit to the Series to be derived from purchases of
foreign currency options will be reduced by the amount of the premium and
related transaction costs. In addition, where currency exchange rates do not
move in the direction or to the extent anticipated, a Series could sustain
losses on transactions in foreign currency options which would require it to
forego a portion or all of the benefits of advantageous changes in such rates.

The Series may write options on foreign currencies for the same types of hedging
purposes. For example, where a Series anticipates a decline in the dollar value
of foreign currency denominated securities due to adverse fluctuations in
exchange rates, it could, instead of purchasing a put option, write a call
option on the relevant currency. If the expected decline occurs, the option will
most likely not be exercised, and the diminution in the value of portfolio
securities will be offset by the amount of the premium received.

Similarly, instead of purchasing a call option to hedge against an anticipated
increase in the dollar cost of securities to be acquired, a Series could write a
put option on the relevant currency which, if rates move in the manner
projected, will expire unexercised and allow the Series to hedge such increased
cost up to the amount of the premium. As in the case of other types of options,
however, the writing of a foreign currency option will constitute only a partial
hedge up to the amount of the premium, and only if rates move in the expected
direction. If this does not occur, the option may be exercised and the Series
would be required to purchase or sell the underlying currency at a loss which
may not be offset by the amount of the premium. Through the writing of options
on foreign currencies, a Series also may be required to forego all or a portion
of the benefit which might otherwise have been obtained from favorable movements
in exchange rates.

The Series may write covered call options on foreign currencies. A call option
written on a foreign currency by a Series is "covered" if the Series owns the
underlying foreign currency covered by the call or has an absolute and immediate
right to acquire that foreign currency without additional cash consideration (or
for additional cash consideration held in a segregated account by the custodian
bank) upon conversion or exchange of other foreign currency held in its
portfolio. A call option is also covered if a Series has a call on the same
foreign currency and in the same principal amount as the call written where the
exercise price of the call held (a) is equal to or less than the exercise price
of the call written, or (b) is greater than the exercise price of the call
written if the difference is maintained by the Series in Segregated Assets in a
segregated account with its custodian bank.

With respect to writing put options, at the time the put is written, a Series
will establish a segregated account with its custodian bank consisting of
Segregated Assets in an amount equal in value to the amount the Series will be
required to pay upon exercise of the put. The account will be maintained until
the put is exercised, has expired, or the Series has purchased a closing put of
the same series as the one previously written.

INVESTMENTS RELATING TO THE GLOBAL FUND, GLOBAL BOND FUND, U.S. BALANCED FUND
AND U.S. BOND FUND

The following discussion applies to the Global Fund, Global Bond Fund, U.S.
Balanced Fund and U.S. Bond Fund.

LOWER RATED DEBT SECURITIES
- ----------------------------

Fixed income securities rated lower than Baa by Moody's Investors Services, Inc.
or BBB by Standard & Poor's Ratings Group are considered to be of poor standing
and predominantly speculative. Such securities ("lower rated securities") are
commonly referred to as "junk bonds" and are subject to a substantial degree of
credit risk. Lower rated securities may be issued as a consequence of corporate
restructurings, such as leveraged buy-outs, mergers, acquisitions, debt
recapitalizations or similar events. Also, lower rated securities are often
issued by smaller, less creditworthy companies or by highly leveraged (indebted)
firms, which are generally less able than more financially stable firms to make
scheduled payments of interest and principal. The risks posed by securities
issued under such circumstances are substantial.

In the past, the high yields from lower rated securities have more than
compensated for the higher default rates on such securities. However, there can
be no assurance that diversification will protect the Series from widespread
bond defaults

                                       12
<PAGE>
 
brought about by a sustained economic downturn, or that yields will continue to
offset default rates on lower rated securities in the future. Issuers of these
securities are often highly leveraged, so that their ability to service their
debt obligations during an economic downturn or during sustained periods of
rising interest rates may be impaired. In addition, such issuers may not have
more traditional methods of financing available to them and may be unable to
repay debt at maturity by refinancing. Further, an economic recession may result
in default levels with respect to such securities in excess of historic
averages.

The value of lower-rated securities will be influenced not only by changing
interest rates, but also by the bond market's perception of credit quality and
the outlook for economic growth. When economic conditions appear to be
deteriorating, lower rated securities may decline in market value due to
investors' heightened concern over credit quality, regardless of prevailing
interest rates.

Especially at such times, trading in the secondary market for lower rated
securities may become thin and market liquidity may be significantly reduced.
Even under normal conditions, the market for lower rated securities may be less
liquid than the market for investment grade corporate bonds. There are fewer
securities dealers in the high yield market and purchasers of lower rated
securities are concentrated among a smaller group of securities dealers and
institutional investors. In periods of reduced market liquidity, lower rated
securities prices may become more volatile.

Besides credit and liquidity concerns, prices for lower rated securities may be
affected by legislative and regulatory developments. For example, from time to
time, Congress has considered legislation to restrict or eliminate the corporate
tax deduction for interest payments or to regulate corporate restructurings such
as takeovers or mergers. Such legislation may significantly depress the prices
of outstanding lower rated securities. A description of various corporate debt
ratings appears in Appendix A to this Statement of Additional Information.

CONVERTIBLE SECURITIES
- ----------------------

The Series may invest in convertible securities which generally offer lower
interest or dividend yields than non-convertible debt securities of similar
quality. The value of convertible securities may reflect changes in the value of
the underlying common stock. Convertible securities entail less credit risk than
the issuer's common stock because they rank senior to common stock. Convertible
securities entitle the holder to exchange the securities for a specified number
of shares of common stock, usually of the same company, at specified prices
within a certain period of time and to receive interest or dividends until the
holder elects to convert. The provisions of any convertible security determine
its ranking in a company's capital structure. In the case of subordinated
convertible debentures, the holder's claims on assets and earnings are
subordinated to the claims of other creditors and are senior to the claims of
preferred and common shareholders. In the case of preferred stock and
convertible preferred stock, the holder's claim on assets and earnings are
subordinated to the claims of all creditors but are senior to the claims of
common shareholders.

WHEN-ISSUED SECURITIES
- ----------------------

The Series may purchase securities offered on a "when-issued" or "forward
delivery" basis. When so offered, the price, which is generally expressed in
yield terms, is fixed at the time the commitment to purchase is made, but
delivery and payment for the when-issued or forward delivery securities take
place at a later date. During the period between purchase and settlement, no
payment is made by the purchaser to the issuer and no interest on the when-
issued or forward delivery security accrues to the purchaser. While when-issued
or forward delivery securities may be sold prior to the settlement date, it is
intended that a Series will purchase such securities with the purpose of
actually acquiring them unless a sale appears desirable for investment reasons.
At the time a Series makes the commitment to purchase a security on a when-
issued or forward delivery basis, it will record the transaction and reflect the
value of the security in determining its net asset value. The market value of
when-issued or forward delivery securities may be more or less than the purchase
price. The Advisor does not believe that a Series' net asset value or income
will be adversely affected by its purchase of securities on a when-issued or
forward delivery basis. The Series will establish a segregated account in which
it will maintain Segregated Assets equal in value to commitments for when-issued
or forward delivery securities.

MORTGAGE-BACKED SECURITIES AND MORTGAGE PASS-THROUGH SECURITIES
- ---------------------------------------------------------------

The Series may also invest in mortgage-backed securities, which are interests in
pools of mortgage loans, including mortgage loans made by savings and loan
institutions, mortgage bankers, commercial banks and others. Pools of

                                       13
<PAGE>
 
mortgage loans are assembled as securities for sale to investors by various
governmental, government-related and private organizations as further described
below. The Series may also invest in debt securities which are secured with
collateral consisting of mortgage-backed securities (see "Collateralized
Mortgage Obligations") and in other types of mortgage-related securities.

The timely payment of principal and interest on mortgage-backed securities
issued or guaranteed by the Government National Mortgage Association ("GNMA") is
backed by GNMA and the full faith and credit of the U.S. government. These
guarantees, however, do not apply to the market value of Series shares. Also,
securities issued by GNMA and other mortgage-backed securities may be purchased
at a premium over the maturity value of the underlying mortgages. This premium
is not guaranteed and would be lost if prepayment occurs. Mortgage-backed
securities issued by U.S. government agencies or instrumentalities other than
GNMA are not "full faith and credit" obligations. Certain obligations, such as
those issued by the Federal Home Loan Bank are supported by the issuer's right
to borrow from the U.S. Treasury, while others such as those issued by the
Federal National Mortgage Association ("FNMA"), are supported only by the credit
of the issuer. Unscheduled or early payments on the underlying mortgages may
shorten the securities' effective maturities and reduce returns. The Series may
agree to purchase or sell these securities with payment and delivery taking
place at a future date. A decline in interest rates may lead to a faster rate of
repayment of the underlying mortgages and expose the Series to a lower rate of
return upon reinvestment. To the extent that such mortgage-backed securities are
held by a Series, the prepayment right of mortgagors may limit the increase in
net asset value of the Series because the value of the mortgage-backed
securities held by the Series may not appreciate as rapidly as the price of
noncallable debt securities.

A decline in interest rates may lead to a faster rate of repayment of the
underlying mortgages and expose a Series to a lower rate of return upon
reinvestment. To the extent that such mortgage-backed securities are held by a
Series, the prepayment right will tend to limit to some degree the increase in
net asset value of the Series because the value of the mortgage-backed
securities held by the Series may not appreciate as rapidly as the price of
noncallable debt securities.

For federal tax purposes other than diversification under Subchapter M, mortgage
backed securities are not considered to be separate securities but rather
"grantor trusts" conveying to the holder an individual interest in each of the
mortgages constituting the pool.

Interests in pools of mortgage-backed securities differ from other forms of debt
securities, which normally provide for periodic payment of interest in fixed
amounts with principal payments at maturity or specified call dates. Instead,
these securities provide a monthly payment which consists of both interest and
principal payments. In effect, these payments are a "pass-through" of the
monthly payments made by the individual borrowers on their mortgage loans, net
of any fees paid to the issuer or guarantor of such securities. Additional
payments are caused by repayments of principal resulting from the sale of the
underlying property, refinancing or foreclosure, net of fees or costs which may
be incurred. Some mortgage-backed securities (such as securities issued by the
GNMA) are described as "modified pass-through." These securities entitle the
holder to receive all interest and principal payments owed on the mortgage pool,
net of certain fees, at the scheduled payments dates regardless of whether or
not the mortgagor actually makes the payment.

Any discount enjoyed on the purchases of a pass-through type mortgage-backed
security will likely constitute market discount. As a Series receives principal
payments, it will be required to treat as ordinary income an amount equal to the
lesser of the amount of the payment or the "accrued market discount." Market
discount is to be accrued either under a constant rate method or a proportional
method. Pass-through type mortgage-backed securities purchased at a premium to
face will be subject to a similar rule requiring recognition of an offset to
ordinary interest income, an amount of premium attributable to the receipt of
principal. The amount of premium recovered is to be determined using a method
similar to that in place for market discount. A Series may elect to accrue
market discount or amortize premium notwithstanding the amount of principal
received but such election will apply to all bonds held and thereafter acquired
unless permission is granted by the Commissioner of the Internal Revenue Service
to change such method.

The principal governmental guarantor of mortgage-related securities is GNMA,
which is a wholly-owned U. S. government corporation within the Department of
Housing and Urban Development. GNMA is authorized to guarantee, with the full
faith and credit of the U.S. government, the timely payment of principal and
interest on securities issued by institutions approved by GNMA (such as savings
and loan institutions, commercial banks and mortgage bankers) 
                                       14
<PAGE>
 
and backed by pools of mortgages which are insured by the Federal Housing
Authority or guaranteed by the Veterans Administration. These guarantees,
however, do not apply to the market value or yield of mortgage-backed securities
or to the value of Series shares. Also, GNMA securities often are purchased at a
premium over the maturity value of the underlying mortgages. This premium is not
guaranteed and should be viewed as an economic offset to interest to be earned.
If prepayments occur, less interest will be earned and the value of the premium
paid will be lost.

Government-related guarantors (i.e., not backed by the full faith and credit of
the U.S. government) include FNMA and the Federal Home Loan Mortgage Corporation
("FHLMC"). FNMA is a government-sponsored corporation owned entirely by private
stockholders. It is subject to general regulation of the Secretary of Housing
and Urban Development. FNMA purchases conventional (i.e., not insured or
guaranteed by any government agency) mortgages from a list of approved
seller/servicers which include state and federally chartered savings and loan
associations, mutual savings banks, commercial banks and credit unions and
mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to
timely payment of principal and interest by FNMA but are not backed by the full
faith and credit of the U.S. government.

FHLMC is a corporate instrumentality of the U.S. government and was created by
Congress in 1970 for the purpose of increasing the availability of mortgage
credit for residential housing. Its stock is owned by the twelve Federal Home
Loan Banks. FHLMC issues Participation Certificates ("PCs") which represent
interests in conventional mortgages from FHLMC's national portfolio. FHLMC
guarantees the timely payment of interest and ultimate collection of principal,
but PCs are not backed by the full faith and credit of the U.S. government.

Commercial banks, savings and loan institutions, private mortgage insurance
companies, mortgage bankers and other secondary market issuers also create pass-
through pools of conventional mortgage loans. Such issuers may, in addition, be
the originators and/or servicers of the underlying mortgage loans as well as the
guarantors of the mortgage-related securities. Pools created by such non-
governmental issuers generally offer a higher rate of interest than government
and government-related pools because there are no direct or indirect government
or agency guarantees of payments. However, timely payment of interest and
principal of these pools may be supported by various forms of insurance or
guarantees, including individual loan, title, pool and hazard insurance and
letters of credit. The insurance guarantees are issued by governmental entities,
private insurers and the mortgage poolers. Such insurance and guarantees and the
creditworthiness of the issuers thereof will be considered in determining
whether a mortgage-related security meets a Series' investment quality
standards. There can be no assurance that the private insurers or guarantors can
meet their obligations under the insurance policies or guarantee or guarantees,
even if through an examination of the loan experience and practices of the
originators/servicers and poolers, the Advisor determines that the securities
meet the Series' quality standards. Although the market for such securities is
becoming increasingly liquid, securities issued by certain private organizations
may not be readily marketable.

COLLATERALIZED MORTGAGE OBLIGATIONS ("CMOS") AND REAL ESTATE MORTGAGE INVESTMENT
- --------------------------------------------------------------------------------
CONDUITS ("REMICS")
- -------------------

A CMO is a debt security on which interest and prepaid principal are paid, in
most cases, semi-annually. 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 and their income streams.
Privately-issued CMOs tend to be more sensitive to interest rates than
Government-issued CMOs.

CMOs are structured into multiple classes, each bearing a different stated
maturity. Actual maturity and average life will depend upon the prepayment
experience of the collateral. CMOs provide for a modified form of call
protection through a de facto breakdown of the underlying pool of mortgages
according to how quickly the loans are repaid. Monthly payments of principal
received from the pool of underlying mortgages, including prepayments, is 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. An investor is partially guarded against a sooner than desired return
of principal because of the sequential payments.
 
In a typical CMO transaction, a corporation issues multiple series (e.g., A, B,
C, Z) of CMO bonds ("Bonds"). Proceeds of the Bond offering are used to purchase
mortgages or mortgage pass-through certificates ("Collateral"). The Collateral
is pledged to a third party trustee as security for the Bonds. Principal and
interest payments from the Collateral are used to pay principal on the Bonds in
the order A, B, C, Z. The Series A, B and C Bonds all bear current interest.
Interest

                                       15
<PAGE>
 
on the Series Z Bond is accrued and added to principal and a like amount is paid
as principal on the Series A, B, or C Bond currently being paid off.  When the
Series A, B and C Bonds are paid in full, interest and principal on the Series
Z Bond begins to be paid currently.  With some CMOs, the issuer serves as a
conduit to allow loan originators (primarily builders or savings and loan
associations) to borrow against their loan portfolios.  REMICs are private
entities formed for the purpose of holding a fixed pool of mortgages secured by
an interest in real property.  REMICs are similar to CMOs in that they issue
multiple classes of securities.

Most if not all newly-issued debt securities backed by pools of real estate
mortgages will be issued as regular and residual interests in REMICs because, as
of January 1, 1992, new CMOs which do not make REMIC elections will be treated
as "taxable mortgage pools," a wholly undesirable tax result.  Under certain
transition rules, CMOs in existence on December 31, 1991 are unaffected by this
change.  The Series will purchase only regular interests in REMICs. REMIC
regular interests are treated as debt of the REMIC and income/discount thereon
must be accounted for on the "catch-up method," using a reasonable prepayment
assumption under the original issue discount rules of the Code.

CMOs and REMICs issued by private entities are not government securities and are
not directly guaranteed by any government agency.  They are secured by the
underlying collateral of the private issuer.  Yields on privately-issued CMOs,
as described above, have been historically higher than yields on CMOs issued or
guaranteed by U.S. government agencies. However, the risk of loss due to default
on such instruments is higher since they are not guaranteed by the U.S.
government.  Such instruments also tend to be more sensitive to interest rates
than U.S. government-issued CMOs.  The Series will not invest in subordinated
privately-issued CMOs.  For federal income tax purposes, the Series will be
required to accrue income on CMOs and REMIC regular interests using the "catch-
up" method, with an aggregate prepayment assumption.

OTHER MORTGAGE-BACKED SECURITIES
- --------------------------------

The Advisor expects that governmental, government-related or private entities
may create mortgage loan pools and other mortgage-related securities offering
mortgage pass-through and mortgage-collateralized investments in addition to
those described above.  The mortgages underlying these securities may include
alternative mortgage instruments, that is, mortgage instruments whose principal
or interest payments may vary or whose terms to maturity may differ from
customary long-term fixed rate mortgages.  As new types of mortgage-related
securities are developed and offered to investors, the Advisor will, consistent
with a Series' investment objective, policies and quality standards, consider
making investments in such new types of mortgage-related securities.  The
Advisor will not purchase any such other mortgage-backed securities until the
Series' Prospectuses and this Statement of Additional Information have been
supplemented.

ASSET-BACKED SECURITIES
- -----------------------

The Series may invest a portion of its assets in debt obligations known as
"asset-backed securities." Asset-backed securities are securities that represent
a participation in, or are secured by and payable from, a stream of payments
generated by particular assets, most often a pool or pools of similar assets
(e.g., receivables on home equity and credit loans and receivables regarding
automobile, credit card, mobile home and recreational vehicle loans, wholesale
dealer floor plans and leases).

Such receivables are securitized in either a pass-through or a pay-through
structure.  Pass-through securities provide investors with an income stream
consisting of both principal and interest payments in respect of the receivables
in the underlying pool.  Pay-through asset-backed securities are debt
obligations issued usually by a special purpose entity, which are collateralized
by the various receivables and in which the payments on the underlying
receivables provide that the Series pay the debt service on the debt obligations
issued.  The Series may invest in these and other types of asset-backed
securities that may be developed in the future.

The credit quality of these securities depends primarily upon the quality of the
underlying assets and the level of credit support and/or enhancement provided.
Such asset-backed securities are subject to the same prepayment risks as
mortgage-backed securities.  For federal income tax purposes, the Series will be
required to accrue income on pay-through asset-backed securities using the
"catch-up" method, with an aggregate prepayment assumption.

                                       16
<PAGE>
 
The credit quality of most asset-backed securities depends primarily on the
credit quality of the assets underlying such securities, how well the entity
issuing the security is insulated from the credit risk of the originator or any
other affiliated entities, and the amount and quality of any credit support
provided to the securities.  The rate of principal payment on asset-backed
securities generally depends on the rate of principal payments received on the
underlying assets which in turn may be affected by a variety of economic and
other factors.  As a result, the yield on any asset-backed security is difficult
to predict with precision and actual yield to maturity may be more or less than
the anticipated yield to maturity. Asset-backed securities may be classified as
"pass-through certificates" or "collateralized obligations."

Asset-backed securities are often backed by a pool of assets representing the
obligations of a number of different parties. To lessen the effect of failures
by obligors on underlying assets to make payment, such securities may contain
elements of credit support.  Such credit support falls into two categories:  (i)
liquidity protection; and (ii) protection against losses resulting from ultimate
default by an obligor on the underlying assets.  Liquidity protection refers to
the provision of advances, generally by the entity administering the pool of
assets, to ensure that the receipt of payments due on the underlying pool is
timely.  Protection against losses resulting from ultimate default enhances the
likelihood of payments of the obligations on at least some of the assets in the
pool.  Such protection may be provided through guarantees, insurance policies or
letters of credit obtained by the issuer or sponsor from third parties, through
various means of structuring the transaction or through a combination of such
approaches.  The Series will not pay any additional fees for such credit
support, although the existence of credit support may increase the price of a
security.

Due to the shorter maturity of the collateral backing such securities, there is
less of a risk of substantial prepayment than with mortgage-backed securities.
Such asset-backed securities do, however, involve certain risks not associated
with mortgage-backed securities, including the risk that security interests
cannot be adequately, or in many cases, ever, established.  In addition, with
respect to credit card receivables, a number of state and federal consumer
credit laws give debtors the right to set off certain amounts owed on the credit
cards, thereby reducing the outstanding balance.  In the case of automobile
receivables, there is a risk that the holders may not have either a proper or
first security interest in all of the obligations backing such receivables due
to the large number of vehicles involved in a typical issuance and technical
requirements under state laws.  Therefore, recoveries on repossessed collateral
may not always be available to support payments on the securities.

Examples of credit support arising out of the structure of the transaction
include "senior-subordinated securities" (multiple class securities with one or
more classes subordinate to other classes as to the payment of principal thereof
and interest thereon, with the result that defaults on the underlying assets are
borne first by the holders of the subordinated class), creation of "reserve
funds" (where cash or investments, sometimes funded from a portion of the
payments on the underlying assets, are held in reserve against future losses)
and "over collateralization" (where the scheduled payments on, or the principal
amount of, the underlying assets exceeds that required to make payments of the
securities and pay any servicing or other fees).  The degree of credit support
provided for each issue is generally based on historical information respecting
the level of credit information respecting the level of credit risk associated
with the underlying assets.  Delinquencies or losses in excess of those
anticipated could adversely affect the return on an investment in such issue.

ZERO COUPON AND DELAYED INTEREST SECURITIES
- -------------------------------------------

The Series may invest in zero coupon or delayed interest securities which pay no
cash income until maturity or a specified date when the securities begin paying
current interest (the "cash payment date") and are sold at substantial discounts
from their value at maturity. When held to maturity or cash payment date, the
entire income of such securities, which consists of accretion of discount, comes
from the difference between the purchase price and their value at maturity or
cash payment date. The discount varies depending on the time remaining until
maturity or cash payment date, prevailing interest rates, liquidity of the
security and the perceived credit quality of the issuer. The discount, in the
absence of financial difficulties of the issuer, decreases as the final maturity
or cash payment date of the security approaches. The market prices of zero
coupon and delayed interest securities are generally more volatile and more
likely to respond to changes in interest rates than the market prices of
securities having similar maturities and credit qualities that pay interest
periodically. Current federal income tax law requires that a holder of a zero
coupon security report as income each year the portion of the original issue
discount on such security (other than tax-exempt original issue discount from a
zero coupon security) that accrues that year, even though the holder receives no
cash payments of interest during the year. The Series will be required to
distribute such income to shareholders to comply with Subchapter M of the Code
and avoid excise taxes, even though the Series have not received any cash from
the issue.

                                       17
<PAGE>
 
Zero coupon securities are subject to greater market value fluctuations from
changing interest rates than debt obligations of comparable maturities which
make current distributions of interest (cash).  Zero coupon convertible
securities offer the opportunity for capital appreciation as increases (or
decreases) in market value of such securities closely follow the movements in
the market value of the underlying common stock.  Zero coupon convertible
securities generally are expected to be less volatile than the underlying common
stocks as they usually are issued with short maturities (15 years or less) and
are issued with options and/or redemption features exercisable by the holder of
the obligation entitling the holder to redeem the obligation and receive a
defined cash payment.

Zero coupon securities include securities issued directly by the U.S. Treasury,
and U.S. Treasury bonds or notes and their unmatured interest coupons and
receipts for their underlying principal ("coupons") which have been separated by
their holder, typically a custodian bank or investment brokerage firm.  A holder
will separate the interest coupons from the underlying principal (the "corpus")
of the U.S. Treasury security.  A number of securities firms and banks have
stripped the interest coupons and receipts and then resold them in custodial
receipt programs with a number of different names, including "Treasury Income
Growth Receipts" ("TIGRS") and Certificate of Accrual on Treasuries ("CATS").
The underlying U.S. Treasury bonds and notes themselves are held in book-entry
form at the Federal Reserve Bank or, in the case of bearer securities (i.e.,
unregistered securities which are owned ostensibly by the bearer or holder
thereof), in trust on behalf of the owners thereof.  Counsel to the underwriters
of these certificates or other evidences of ownership of the U.S. Treasury
securities has stated that for federal tax and securities purposes, in its
opinion, purchasers of such certificates, such as the Series, most likely will
be deemed the beneficial holder of the underlying U.S. government securities.
The Series understand that the staff of the SEC no longer considers such
privately stripped obligations to be U.S. government securities, as defined in
the Act; therefore, the Series intends to adhere to this staff position and
will not treat such privately stripped obligations to be U.S. government
securities for the purpose of determining if the Series is "diversified," or for
any other purpose, under the Act.

The U.S. Treasury has facilitated transfers of ownership of zero coupon
securities by accounting separately for the beneficial ownership of particular
interest coupon and corpus payments on Treasury securities through the Federal
Reserve book-entry record-keeping system.  The Federal Reserve program as
established by the U.S. Treasury Department is known as "STRIPS" or "Separate
Trading of Registered Interest and Principal of Securities."  Under the STRIPS
program, a Series will be able to have its beneficial ownership of zero coupon
securities recorded directly in the book-entry record-keeping system in lieu of
having to hold certificates or other evidences of ownership of the underlying
U.S. Treasury securities.

When U.S. Treasury obligations have been stripped of their unmatured interest
coupons by the holder, the principal or corpus is sold at a deep discount
because the buyer receives only the right to receive a future fixed payment on
the security and does not receive any rights to periodic interest (cash)
payments.  Once stripped or separated, the corpus and coupons may be sold
separately.  Typically, the coupons are sold separately or grouped with other
coupons with like maturity dates and sold in such bundled form.  Purchasers of
stripped obligations acquire, in effect, discount obligations that are
economically identical to the zero coupon securities that the U.S. Treasury
sells itself.  These stripped securities are also treated as zero coupon
securities with original issue discount for tax purposes.

INVESTMENTS RELATING TO THE GLOBAL FUND

EMERGING MARKETS INVESTMENTS (Global Fund only).
- ----------------------------

The Series may invest up to 10% of its assets in equity and debt securities of
emerging market issuers, or securities with respect to which the return is
derived from the equity or debt securities of issuers in emerging markets.  The
Series may invest in equity securities of issuers in emerging markets, or
securities with respect to which the return is derived from the equity
securities of issuers in emerging markets.  The Series also may invest in fixed
income securities of emerging market issuers, including government and
government-related entities (including participation in loans between
governments and financial institutions), and of entities organized to
restructure outstanding debt of such issuers.  The Series also may invest in
debt securities of corporate issuers in developing countries.

The Series' investments in emerging market government and government-related
securities may consist of (i) debt securities or obligations issued or
guaranteed by governments, governmental agencies or instrumentalities and
political subdivisions located in emerging countries (including participation in
loans between governments and financial

                                       18
<PAGE>
 
institutions), (ii) debt securities or obligations issued by government owned,
controlled or sponsored entities located in emerging countries and (iii)
interests in issuers organized and operated for the purpose of restructuring the
investment characteristics of instruments issued by any of the entities
described above.

The Series' investments in the fixed income securities of emerging market
issuers may include investments in Brady Bonds, Structured Securities, Loan
Participation and Assignments (as such capitalized terms are defined below), and
certain non-publicly traded securities.

Brady Bonds are securities created through the exchange of existing commercial
bank loans to public and private entities in certain emerging markets for new
bonds in connection with debt restructurings  under a debt restructuring plan
introduced by former U.S. Secretary of the Treasury, Nicholas F. Brady (the
"Brady Plan"). Brady Bonds may be collateralized or uncollateralized, are issued
in various currencies (but primarily the U.S. dollar), and are actively traded
in over-the-counter secondary markets.  Dollar-denominated, collateralized Brady
Bonds, which may be fixed-rate bonds or floating-rate bonds, are generally
collateralized in full as to principal by U.S. Treasury zero coupon bonds having
the same maturity as the bonds.

Structured Securities are issued by entities organized and operated solely for
the purpose of restructuring the investment characteristics of sovereign debt
obligations.  This type of restructuring involves the deposit with, or purchase
by, an entity, such as a corporation or trust, of specified instruments (such as
commercial bank loans or Brady Bonds) and the issuance by that entity of one or
more classes of securities ("Structured Securities") backed by, or representing
interests in, the underlying instruments.

The Series may invest in fixed rate and floating rate loans ("Loans") arranged
through private negotiations between an issuer of sovereign debt obligations and
one or more financial institutions ("Lenders").  The Series' investments in
Loans are expected in most instances to be in the form of a participation in
loans ("Participation") and assignments of all or a portion of Loans
("Assignments") from third parties.  The Series will have the right to receive
payments of principal, interest and any fees to which they are entitled only
from the Lender selling the Participation and only upon receipt by the Lender of
the payments from the borrower.  In the event of the insolvency of the Lender
selling a Participation, the Series may be treated as a general creditor of the
Lender and may not benefit from any set-off between the Lender and the borrower.

When a Series purchases Assignments from Lenders, it will acquire direct rights
against the borrower on the Loan. However, because Assignments are arranged
through private negotiations between potential assignees and potential
assignors, the rights and obligations acquired by the Series as the purchaser of
an Assignment may differ from, and be more limited than, those held by the
assigning Lender.

The Series also may invest in securities that are neither listed on a stock
exchange nor traded over-the-counter, including privately placed securities and
limited partnerships.  Investing in such unlisted emerging market equity
securities, including investments in new and early stage companies, may involve
a high degree of business and financial risk that can result in substantial
losses.  As a result of the absence of a public trading market for these
securities, they may be less liquid than publicly traded securities.

The Series' investments in emerging market securities will at all times be
limited by the Series' prohibition on investing more than 15% of its net assets
in illiquid securities.

RISKS OF INVESTING IN EMERGING MARKETS
- --------------------------------------

Compared to the United States and other developed countries, emerging countries
may have relatively unstable governments, economies based on only a few
industries, and securities markets that trade only a small number of securities
and employ settlement procedures different from those used in the United States.
Prices on these exchanges tend to be volatile and, in the past, securities in
these countries have offered greater potential for gain (as well as loss) than
securities of companies located in developed countries.  Further, investments by
foreign investors are subject to a variety of restrictions in many emerging
countries.  Countries such as those in which the Series may invest have
historically experienced and may continue to experience, high rates of
inflation, high interest rates, exchange rate fluctuations or currency
depreciation, large amounts of external debt, balance of payments and trade
difficulties and

                                       19

extreme poverty and unemployment.  Additional factors which may influence the
ability or willingness to service debt include, but are not limited to, a
country's cash flow situation, the availability of sufficient foreign exchange
on the date a payment is due, the relative size of its debt service burden to
the economy as a whole, its government's policy towards the International
Monetary Fund, the World Bank and other international agencies and the political
constraints to which a government debtor may be subject.

The ability of a foreign government or government-related issuer to make timely
and ultimate payments on its external debt obligations will be strongly
influenced by the issuer's balance of payments, including export performance,
its access to international credits and investments, fluctuations in interest
rates and the extent of its foreign reserves.  A country whose exports are
concentrated in a few commodities or whose economy depends on certain strategic
imports could be vulnerable to fluctuations in international prices of these
commodities or imports.  To the extent that a country receives payment for its
exports in currencies other than dollars, its ability to make debt payments
denominated in dollars could be adversely affected.  If a foreign government or
government-related issuer cannot generate sufficient earnings from foreign trade
to service its external debt, it may need to depend on continuing loans and aid
from foreign governments, commercial banks, and multilateral organizations, and
inflows of foreign investment.  The commitment on the part of these foreign
governments, multilateral organizations and others to make such disbursements
may be conditioned on the government's implementation of economic reforms and/or
economic performance and the timely service of its obligations.  Failure to
implement such reforms, achieve such levels of economic performance or repay
principal or interest when due may curtail the willingness of such third parties
to lend funds, which may further impair the issuer's ability or willingness to
service its debts in a timely manner.  The cost of servicing external debt will
also generally be adversely affected by rising international interest rates,
because many external debt obligations bear interest at rates which are adjusted
based upon international interest rates.  The ability to service external debt
will also depend on the level of the relevant government's international
currency reserves and its access to foreign exchange.  Currency devaluations may
affect the ability of a governmental issuer to obtain sufficient foreign
exchange to service its external debt.

As a result of the foregoing, a governmental issuer may default on its
obligations.  If such a default occurs, the Series may have limited effective
legal recourse against the issuer and/or guarantor.  Remedies must, in some
cases, be pursued in the courts of the defaulting country itself, and the
ability of the holder of foreign government and government-related debt
securities to obtain recourse may be subject to the political climate in the
relevant country.  In addition, no assurance can be given that the holders of
commercial bank debt will not contest payments to the holders of other foreign
government and government-related debt obligations in the event of default under
their commercial bank loan agreements.

The issuers of the government and government-related debt securities in which
the Series expects to invest have in the past experienced substantial
difficulties in servicing their external debt obligations, which has led to
defaults on certain obligations and the restructuring of certain indebtedness.
Restructuring arrangements have included, among other things, reducing and
rescheduling interest and principal payments by negotiating new or amended
credit agreements or converting outstanding principal and unpaid interest to
Brady Bonds, and obtaining new credit to finance interest payments.  Holders of
certain foreign government and government-related debt securities may be
requested to participate in the restructuring of such obligations and to extend
further loans to their issuers.  There can be no assurance that the Brady Bonds
and other foreign government and government-related debt securities in which the
Series may invest will not be subject to similar defaults or restructuring
arrangements which may adversely affect the value of such investments.
Furthermore, certain participants in the secondary market for such debt may be
directly involved in negotiating the terms of these arrangements and may
therefore have access to information not available to other market participants.

Payments to holders of the high yield, high risk, foreign debt securities in
which the Series may invest may be subject to foreign withholding and other
taxes.  Although the holders of foreign government and government-related debt
securities may be entitled to tax gross-up payments from the issuers of such
instruments, there is no assurance that such payments will be made.

INVESTMENTS IN AFFILIATED INVESTMENT COMPANIES
- ----------------------------------------------

The Series may invest in securities issued by other registered investment
companies advised by Brinson Partners

                                       20
<PAGE>
 
pursuant to exemptive relief granted by the SEC.  Currently, the Global Fund is
the only Series of the Trust that intends to invest in portfolios of Brinson
Relationship Funds, another investment company which is advised by Brinson
Partners, and only to the extent consistent with the Advisor's investment
process of allocating assets to specific asset classes.  The Global Fund will
invest in corresponding portfolios of Brinson Relationship Funds only to the
extent that the Advisor determines that such investments are a more efficient
means for the Global Fund to gain exposure to the asset classes referred to
below than by investing directly in individual securities.

To gain exposure to equity and fixed income securities of issuers located in
emerging market countries, the Global Fund may invest that portion of its
assets allocated to emerging markets investments in the Brinson Emerging Markets
Equity Fund portfolio and the Brinson Emerging Markets Debt Fund portfolio of
Brinson Relationship Funds.  The investment objective of the Brinson Emerging
Markets Equity Fund and the Brinson Emerging Markets Debt Fund is to maximize
total U.S. dollar return, consisting of capital appreciation and current income,
while controlling risk.  Under normal circumstances, at least 65% of the total
assets of the Brinson Emerging Markets Equity Fund is invested in the equity
securities of issuers in emerging markets or securities with respect to which
the return is derived from the equity securities of issuers in emerging markets.
At least 65% of the total assets of the Brinson Emerging Markets Debt Fund is
invested in the debt securities issued by governments, government-related
entities (including participations in loans between governments and financial
institutions), corporations and entities organized to restructure outstanding
debt of issuers in emerging markets, or debt securities the return on which is
derived primarily from other emerging markets instruments.  The Brinson Emerging
Markets Equity Fund and Brinson Emerging Markets Debt Fund are permitted to
invest in the same types of securities as the Global Fund may invest in
directly.

In lieu of investing directly in certain high yield, higher risk securities, the
Global Fund may invest a portion of its assets in the Brinson High Yield Fund
portfolio (the "High Yield Fund") of Brinson Relationship Funds.  The investment
objective of the High Yield Fund is to maximize total U.S. dollar return,
consisting of capital appreciation and current income, while controlling risk.
The High Yield Fund maintains a high yield portfolio and as such, at least 65%
of its assets are invested in high yield securities.  The Global Fund currently
intends to limit its investment in non-investment grade debt securities to no
more than 5% of its net assets.  Any investment in the High Yield Fund will be
considered within this limitation.
    
In lieu of investing directly in equity securities issued by companies with
relatively small overall market capitalizations, the Global Fund may invest a
portion of its assets in the Brinson Post-Venture Fund portfolio (the "Post-
Venture Fund") of Brinson Relationship Funds. The investment objective of the
Post-Venture Fund is to maximize total U.S. dollar return, consisting of capital
appreciation and current income, while controlling risk. The Post-Venture Fund
invests primarily in publicly- traded companies representing the lower 5% of the
Wilshire 5000 Index, and, as such, at least 65% of its assets are invested in
small capitalization equity securities.     

Each portfolio of Brinson Relationship Funds in which the Global Fund may invest
is permitted to invest in the same securities of a particular asset class in
which the Global Fund is permitted to invest directly, and with similar risks.
Pursuant to undertakings with the SEC, the Global Fund will not be subject to
the imposition of double management or administration fees with respect to its
investments in Brinson Relationship Funds.
    
INVESTMENT RESTRICTIONS     

The investment restrictions set forth below are fundamental policies and may not
be changed as to a Series, without the approval of a majority of the outstanding
voting securities (as defined in the Act) of the Series.  Unless otherwise
indicated, all percentage limitations listed below apply to the Series only at
the time of the transaction.  Accordingly, if a percentage restriction is
adhered to at the time of investment, a later increase or decrease in the
percentage which results from a relative change in values or from a change in a
Series' total assets will not be considered a violation.

Except as set forth under "Investment Objectives and Policies" and "Investment
Considerations and Risks" in each Prospectus, or "Investment Strategies" in
this Statement of Additional Information, each Series may not:

      (i)    As to 75% of the total assets of each Series, purchase the 
             securities of any one issuer, other than securities issued by the
             U.S. government or its agencies or instrumentalities, if

                                       21
<PAGE>

     
            immediately after such purchase more than 5% of the value of the
            total assets of a Series would be invested in securities of such
            issuer (this does not apply to the Global Bond Fund or the U.S. 
            Large Capitalization Equity Fund);      
    
     (ii)   Invest in real estate or interests in real estate (this will not 
            prevent a Series from investing in publicly-held real estate
            investment trusts or marketable securities of companies which may
            represent indirect interests in real estate), interests in oil, gas
            and/or mineral exploration or development programs or leases;     

     (iii)  Purchase or sell commodities or commodity contracts, but may enter
            into futures contracts and options thereon in accordance with its
            Prospectus. Additionally, each Series may engage in forward foreign
            currency contracts for hedging and non-hedging purposes;

     (iv)   Make investments in securities for the purpose of exercising 
            control over or management of the issuer;

     (v)    Purchase the securities of any one issuer if, immediately after such
            purchase, a Series would own more than 10% of the outstanding voting
            securities of such issuer;

     (vi)   Sell securities short or purchase securities on margin, except such
            short-term credits as are necessary for the clearance of
            transactions. For this purpose, the deposit or payment by a Series
            for initial or maintenance margin in connection with futures
            contracts is not considered to be the purchase or sale of a security
            on margin;

     (vii)  Make loans, except that this restriction shall not prohibit (a) the
            purchase and holding of a portion of an issue of publicly
            distributed or privately placed debt securities, (b) the lending of
            portfolio securities, or (c) entry into repurchase agreements with
            banks or broker-dealers;

     (viii) Borrow money in excess of 33 1/3% of the value of its assets except
            as a temporary measure for extraordinary or emergency purposes to
            facilitate redemptions or issue senior securities. All borrowings
            will be done from a bank and to the extent that such borrowing
            exceeds 5% of the value of a Series' assets, asset coverage of at
            least 300% is required. A Series will not purchase securities when
            borrowings exceed 5% of that Series' total assets;

     (ix)   Purchase the securities of issuers conducting their principal 
            business activities in the same industry, other than obligations
            issued or guaranteed by the U.S. government, its agencies or
            instrumentalities, if immediately after such purchase, the value of
            a Series' investments in such industry would exceed 25% of the value
            of the total assets of the Series across several countries;

    
     (x)    Act as an underwriter of securities, except that, in connection with
            the disposition of a security, a Series may be deemed to be an
            "underwriter" as that term is defined in the 1933 Act;     

     (xi)   Invest in securities of any open-end investment company, except that
            (i) a Series may purchase securities of money market mutual funds,
            (ii) the Global Fund and Global Equity Fund may each invest in the
            securities of closed-end investment companies at customary brokerage
            commission rates in accordance with the limitations imposed by the
            Act and the rules thereunder, and (iii) in accordance with any
            exemptive order obtained from the SEC which permits investment by a
            Series in other Series or other investment companies or series
            thereof advised by the Advisor. In addition, each Series may acquire
            securities of other investment companies if the securities are
            acquired pursuant to a merger, consolidation, acquisition, plan of
            reorganization or a SEC approved offer of exchange;

     (xii)  Invest in puts, calls, straddles or combinations thereof except to 
            the extent disclosed in a Series' Prospectus; and

                                       22
<PAGE>
 
     (xiii) Invest more than 5% of its total assets in securities of companies 
            less than three years old. Such three year periods shall include the
            operation of any predecessor company or companies.

UNDERWRITER

FDI, 60 State Street, Suite 1300, Boston, MA 02109, acts as an underwriter of
the Series' continuous offer of shares for the purpose of facilitating the
filing of notices regarding sale of the shares of the Series under state
securities laws and to assist in sales of shares pursuant to an underwriting
agreement (the "Underwriting Agreement") approved by the Board of Trustees. In
this regard, FDI has agreed at its own expense to qualify as a broker-dealer
under all applicable federal or state laws in those states which the Trust shall
from time to time identify to FDI as states in which it wishes to offer the
Series' shares for sale, in order that state filings may be maintained for the
Series. FDI does not receive any compensation under the Underwriting Agreement.

FDI is a broker-dealer registered with the SEC and a member in good standing of
the National Association of Securities Dealers, Inc.

The Trust does not impose any sales loads or redemption fees. Each Series shall
continue to bear the expense of all filing fees incurred in connection with the
filing of notices regarding sale of shares under state securities laws.

The Underwriting Agreement may be terminated by either party upon sixty (60)
days' prior written notice to the other party, and if so terminated, the pro
rata portion of the unearned fee will be returned to the Trust.

The Board of Trustees of the Trust has adopted a distribution plan (the "UBS

Investment Funds class of shares and a separate distribution plan (the "Class N
Plan") pursuant to Rule 12b-1 under the Act for each Series' Brinson Fund-Class
N shares (the UBS Investment Plan and the Class N Plan together, the "Plans").
The Plans permit each Series to reimburse FDI, Brinson Partners and others from
the assets of the UBS Investment Funds class and Brinson Fund-Class N shares
with a quarterly fee for services and expenses incurred in distributing and
promoting sales of UBS Investment Funds class of shares and Brinson Fund-Class N
shares, respectively. The aggregate fees paid by the UBS Investment Funds class
and Brinson Fund-Class N shares to FDI, and others under the Plan for each Class
may not exceed 0.90% of a UBS Investment Fund classes' average daily net assets
and 0.25% of a Brinson Fund-Class N's average daily net assets, respectively, in
any year. The UBS Investment Plan does not apply to the Brinson Fund-Class I or
the Brinson Fund-Class N shares of each Series and those shares are not included
in calculating the UBS Investment Plan's fees. The Class N Plan does not apply
to the Brinson Fund-Class I or the UBS Investment Funds class of shares of each
Series and those shares are not included in calculating the Class N Plan's fees.

CODE OF ETHICS
- --------------

The Trust has adopted a Code of Ethics which establishes standards by which
certain access persons of the Trust, which include officers of the Advisor and
officers and Trustees of the Trust, must abide relating to personal securities
trading conduct.

Under the Code of Ethics, access persons are prohibited from engaging in certain
conduct, including, but not limited to: 1) investing in companies in which the
Series invest unless the securities have a broad public market and are
registered on a national securities exchange or are traded in the over-the-
counter markets; 2) making or maintaining an investment in any corporation or
business with which the Series have business relationships if the investment
might create, or give the appearance of creating, a conflict of interest; 3)
participating in an initial public offering; 4) entering into a securities
transaction when the access person knows or should know that such activity will
anticipate, parallel or counter any securities transaction of a Series; 5)
entering into any securities transaction, without prior approval, in connection
with any security which has been designated as restricted; 6) entering into a
net short position with respect to any security held by a Series; 7) entering
into any derivative transaction when a direct transaction in the underlying
security would be a violation; and 8) engaging in self-dealing or other
transactions benefiting the access person at the expense of the Series or its
shareholders.

In addition, access persons are required to receive advance approval prior to
purchasing or selling a restricted security, and may not buy or sell certain
prohibited securities. The Advisor will identify for access persons prohibited
securities, which include securities that are being considered for purchase or
sale by any account or fund managed by the Advisor,

                                      33
<PAGE>
 
and provide a list of such securities to all access persons. Access persons are
required to file quarterly reports of security investment transactions. Trustees
or officers who are not "interested persons" of the Trust, as defined in the
1940 Act, need only report a transaction in a security if such Trustee or
officer, at the time of the transaction, knew or should have known, in the
ordinary course of fulfilling his or her official duties as a Trustee or
officer, that, during the 15-day period immediately preceding or after the date
of the transaction by the Trustee or officer, such security was purchased or
sold by a Series, or was being considered for purchase by a Series.

PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS

Brinson Partners is responsible for decisions to buy and sell securities for the
Series and for the placement of the Series' portfolio business and the
negotiation of commissions, if any, paid on such transactions. Fixed income
securities in which the Series invest are traded in the over-the-counter market.
These securities are generally traded on a net basis with dealers acting as
principal for their own accounts without a stated commission, although the
bid/ask spread quoted on securities includes an implicit profit to the dealers.
In over-the-counter transactions, orders are placed directly with a principal
market-maker unless a better price and execution can be obtained by using a
broker. Brokerage commissions are paid on transactions in listed securities,
futures contracts and options thereon. Brinson Partners is responsible for
effecting portfolio transactions and will do so in a manner deemed fair and
reasonable to the Series. Under its advisory agreements with the Global Funds
and the Non-U.S. Equity Fund, Brinson Partners is authorized to utilize the
trading desk of its foreign subsidiaries to execute foreign securities
transactions, but monitors the selection by such subsidiaries of brokers and
dealers used to execute transactions for those Series. The primary consideration
in all portfolio transactions will be prompt execution of orders in an efficient
manner at the most favorable price. In selecting and monitoring broker-dealers
and negotiating commissions, Brinson Partners considers the firm's reliability,
the quality of its execution services on a continuing basis and its financial
condition. When more than one firm is believed to meet these criteria,
preference may be given to brokers who provide research or statistical material
or other services to the Series or to Brinson Partners. Such services include
advice, both directly and in writing, as to the value of the securities; the
advisability of investing in, purchasing or selling securities; and the
availability of securities, or purchasers or sellers of securities, as well as
analyses and reports concerning issues, industries, securities, economic factors
and trends, portfolio strategy and the performance of accounts. This allows
Brinson Partners to supplement its own investment research activities and obtain
the views and information of others prior to making investment decisions.
Brinson Partners is of the opinion that, because this material must be analyzed
and reviewed by its staff, its receipt and use does not tend to reduce expenses
but may benefit the Series by supplementing the Advisor's research.

Brinson Partners effects portfolio transactions for other investment companies
and advisory accounts. Research services furnished by dealers through whom the
Series effect its securities transactions may be used by Brinson Partners in
servicing all of its accounts; not all such services may be used in connection
with the Series. In the opinion of Brinson Partners, it is not possible to
measure separately the benefits from research services to each of the accounts
(including the Series). Brinson Partners will attempt to equitably allocate
portfolio transactions among the Series and others whenever concurrent decisions
are made to purchase or sell securities by the Series and another. In making
such allocations between the Series and others, the main factors to be
considered are the respective investment objectives, the relative size of
portfolio holdings of the same or comparable securities, the availability of
cash for investment, the size of investment commitments generally held and the
opinions of the persons responsible for recommending investments to the Series
and the others. In some cases, this procedure could have an adverse effect on
the Series. In the opinion of Brinson Partners, however, the results of such
procedures will, on the whole, be in the best interest of each of the clients.

The Series incurred brokerage commissions as follows:

For the fiscal year ended June 30, 1998 the Trust and the Advisor had no
agreements or understandings with a broker or otherwise causing brokerage
transactions or commissions for research services.           
    
PORTFOLIO TURNOVER      
- ------------------
     
The Series are free to dispose of their portfolio securities at any time,
subject to complying with the Code and the Act, when changes in circumstances or
conditions make such a move desirable in light of the respective investment
objective. The Series will not attempt to achieve or be limited to a
predetermined rate of portfolio turnover, such a turnover always being
incidental to transactions undertaken with a view to achieving that Series'
investment objective.

The Series do not intend to use short-term trading as a primary means of
achieving their investment objectives. The rate of portfolio turnover shall be
calculated by dividing (a) the lesser of purchases and sales of portfolio
securities for the particular fiscal year by (b) the monthly average of the
value of the portfolio securities owned by that Series during the particular
fiscal year. Such monthly average shall be calculated by totaling the values of
the portfolio securities as of the beginning and end of the first month of the
particular fiscal year and as of the end of each of the succeeding eleven months
and dividing the sum by 13.
        
Under normal circumstances, the portfolio turnover rate for the Global Equity
Fund, U.S. Equity Fund, U.S. Large Capitalization Equity Fund and Non-U.S.
Equity Fund is not expected to exceed 100%. The portfolio turnover rates for the
Global Fund and Global Bond Fund may exceed 100% and in some years, 200% and for
the U.S. Balanced Fund and U.S. Bond Fund, may exceed 100% and in some years,
300%. High portfolio turnover rates (over 100%) may involve correspondingly
greater brokerage commissions and other transaction costs, which will be borne
directly by the Series and ultimately by that Series' shareholders. In addition,
high portfolio turnover may result in increased short-term capital gains, which,
when distributed to shareholders, are treated as ordinary income.
   
With respect to the Global Fund, for the fiscal years ended June 30, 1997 and
June 30, 1998, the portfolio turnover rate of the Series was 150% and 88%,
respectively. With respect to the Global Bond Fund, for the fiscal years ended
June 30, 1997 and June 30, 1998 the portfolio turnover rate of the Series was
235% and 151%, respectively. With respect to the Global Equity Fund, for the
fiscal years ended June 30, 1997 and June 30, 1998 the portfolio turnover rate
of the Series was 32% and 46%, respectively. With respect to the Non-U.S. Equity
Fund, for the fiscal years ended June 30, 1997 and June 30, 1998 the portfolio
turnover rate of the Series was 25% and 49%, respectively. With respect to the
U.S. Balanced Fund, for the fiscal years ended June 30, 1997, and June 30, 1998
the portfolio turnover rate of the Series was 329% and 194%, respectively. With
respect to the U.S. Equity Fund, for the fiscal years ended June 30, 1997 and
June 30, 1998 the portfolio turnover rate of the Series was 43% and 42%,
respectively. With respect to the U.S. Large Capitalization Equity Fund, for the
period April 6, 1998 (commencement of operations) to June 30, 1998 the portfolio
turnover rate of the Series was 12%. With respect to the U.S. Bond Fund, for the
fiscal years ended June 30, 1997 and June 30, 1998, the portfolio turnover rate
of the Series was 410% and 198% respectively. The significant variation in
portfolio turnover rates over such periods was due to an increase in the assets
of the Series which caused the Series, to reposition their portfolio holdings in
order to meet their investment objectives and policies.    
    

SHARES OF BENEFICIAL INTEREST
            
The Trust presently offers eight Series of shares of beneficial interest, each
of which offers three classes of shares. Each share of beneficial interest
represents an equal proportionate interest in the assets and liabilities of the
applicable Series and has the same voting and other rights and preferences as
the other class of that Series, except that only shares of the UBS Investment
Funds class may vote on any matter affecting only the UBS Investment Plan under
Rule 12b-1. Similarly, only shares of the Brinson Fund-Class N may vote on
matters that affect only the Class N Plan. No class may vote on matters that
affect only another class. Under Delaware law, the Trust does not normally hold
annual meetings of shareholders. Shareholders' meetings may be held from time to
time to consider certain matters including changes to a Series' fundamental
investment objective and fundamental investment policies, changes to the Trust's
investment advisory agreement and the election of Trustees when required by the
Act. When matters are submitted to shareholders for a vote, shareholders are
entitled to one vote per share with proportionate voting      
     
                                      35
<PAGE>
 
for fractional shares. The shares of the Series do not have cumulative voting
rights or any preemptive or conversion rights, and the Trustees have authority
from time to time to divide or combine the shares of the Series into a greater
or lesser number of shares so affected. In the case of a liquidation of a
Series, each shareholder of the Series will be entitled to share, based upon the
shareholder's percentage share ownership, in the distribution out of assets, net
of liabilities, of the Series. No shareholder is liable for further calls or
assessment by the Series.

On any matters affecting only one Series or class, only the shareholders of that
Series or class are entitled to vote. On matters relating to the Trust but
affecting the Series differently, separate votes by the Series or class are
required. With respect to the submission to shareholder vote of a matter
requiring separate voting by a Series or class, the matter shall have been
effectively acted upon with respect to any Series or class if a majority of the
outstanding voting securities of that Series or class votes for the approval of
the matter, notwithstanding that: (1) the matter has not been approved by a
majority of the outstanding voting securities of any other Series or class; and
(2) the matter has not been approved by a majority of the outstanding voting
securities of the Trust.

PURCHASES
            
Shares of each class of each Series are sold at the net asset value next
determined after the receipt of a purchase application in proper form by the
transfer agent. The minimum for initial investments with respect to the Brinson
Fund-Class I for each Series is $1,000,000; subsequent investment minimums are
$2,500. The minimum for initial investments with respect to the UBS Investment 
Funds class of shares for each Series is $1,000; subsequent investment minimums
are $50. The minimum for initial investment with respect to the Brinson Fund-
Class N for each Series is $1,000,000. A more detailed description of methods of
purchase is included in the Prospectuses.      

Certificates representing shares purchased are not issued. However, such
purchases are confirmed to the investor and credited to the shareholder's
account on the books maintained by the Trust's transfer agent. The investor will
have the same rights of ownership with respect to such shares as if certificates
had been issued.

EXCHANGES OF SHARES
- -------------------

Shares of one class of a Series may only be exchanged for the same class of
another Series of the Trust. Exchanges will not be permitted between the
different classes.
    
Each qualifying exchange will be made on the basis of the relative net asset
values per share of both the Series from which, and the Series into which, the
exchange is made, that is next computed following receipt of the exchange order
in proper form by the Trust's transfer agent. Exchanges may be made by telephone
if the shareholder's Account Application Form includes specific authorization
for telephone exchanges. The telephone exchange privilege may be difficult to
implement during times of drastic economic or market changes.      

The transactions described above will result in a taxable gain or loss for
federal income tax purposes. Generally, any such taxable gain or loss will be a
capital gain or loss (long-term or short-term, depending on the holding period
of the shares) in the amount of the difference between the net asset value of
the shares surrendered and the shareholder's tax basis for those shares. Each
investor should consult his or her tax adviser regarding the tax consequences of
an exchange transaction.

Any shareholder who wishes to make an exchange should first obtain and review
the Prospectus of the Series to be acquired in the exchange. Requests for
telephone exchanges must be received prior to the close of regular trading on
the New York Stock Exchange ("NYSE") on any day on which the NYSE is open for
regular trading.

At the discretion of the Trust, this exchange privilege may be terminated or
modified at any time for any of the participating Series upon 60 days' prior
written notice to shareholders. Contact the transfer agent for details about a
particular exchange.

NET ASSET VALUE
- ---------------

The net asset value per share is calculated separately for each class of each
Series. The net asset value per share of a Series is computed by dividing the
value of the assets of the Series, less its liabilities, by the number of shares
of the Series outstanding.
 
                                      36
<PAGE>
 
Each class of a Series will bear pro rata all of the common expenses of that
Series. The net asset values of all outstanding shares of each class of a Series
will be computed on a pro rata basis for each outstanding share based on the
proportionate participation in the Series represented by the value of shares of
that Series. All income earned and expenses incurred by a Series will be borne
on a pro rata basis by each outstanding share of a class, based on each class'
percentage in the Series represented by the value of such shares of such
classes, except that none of the shares of a class will incur any of the
expenses under the 12b-1 plan of another class.
        
Portfolio securities are valued and net asset value per share is determined as
of the close of regular trading on the NYSE which currently is 4:00 p.m. Eastern
time on each day the NYSE is open for trading. The Series of the Trust reserve
the right to change the time at which purchases, redemptions or exchanges are
priced if the NYSE closes at a time other than 4:00 p.m. Eastern time or if an
emergency exists. The NYSE is open for trading on every day except Saturdays,
Sundays and the following holidays: New Year's Day, Dr. Martin Luther King, Jr. 
Day, Presidents' Day, Good Friday, Memorial Day (day observed), Independence
Day, Labor Day, Thanksgiving Day and Christmas Day and on the preceding Friday
or subsequent Monday when any of these holidays falls on a Saturday or Sunday,
respectively.      

Portfolio securities listed on a national or foreign securities exchange are
valued on the basis of the last sale on the date the valuation is made.
Securities that are not traded on a particular day or an exchange, are valued at
either (a) the bid price or (b) a valuation within the range considered best to
represent value in the circumstances. Price information on listed securities is
generally taken from the closing price on the exchange where the security is
primarily traded. Other portfolio securities which are traded in the over-the-
counter market are valued at the bid price as long as the bid price, in the
opinion of the Advisor, continues to reflect the value of the security.
Valuations of fixed income and equity securities may be obtained from a pricing
service and/or broker-dealers when such prices are believed to reflect the fair
value of such securities. Use of a pricing service and/or broker-dealers has
been approved by the Board of Trustees.
    
Futures contracts are valued at their daily quoted settlement price on the
exchange on which they are traded. Forward foreign currency contracts are
valued daily using the mean between the bid and asked forward points added to
the current exchange rate and an unrealized gain or loss is recorded. A Series
realizes a gain or loss upon settlement of the contracts. Swaps will be priced
at fair value based on (1) swap prices provided by broker-dealers; (2) values,
or estimates of values, of the applicable equity indices and foreign rates
underlying the contracts; and (3) consideration of other relevant factors. A
Series' obligation under a swap agreement will be accrued daily (offset by any
amounts owing to the portfolio) and any accrued but unpaid net amounts owed to
a swap counterparty will be covered by the maintenance of a segregated account
consisting of Segregated Assets. For valuation purposes, foreign securities
initially expressed in foreign currency values will be converted into U.S.
dollar values using WM/Reuters closing spot rates as of 4:00 p.m. London time.
Securities with a remaining maturity of 60 days or less are valued at amortized
cost, which approximates market value. Fixed income securities having a
remaining maturity of over 60 days are valued at market price. Debt securities
are valued on the basis of prices provided by a pricing service, or at the bid
price where readily available, as long as the bid price, in the opinion of the 
Advisor, continues to reflect the value of the security. Redeemable securities
issued by open-end investment companies are valued using their respective net
asset values for purchase orders placed at the close of the NYSE. Securities
(including over-the-counter options) for which market quotations are not readily
available and other assets are valued at their fair value as determined in good
faith by or under the direction of the Trustees.      

Because of time zone differences, foreign exchanges and securities markets will
usually be closed prior to the time of the closing of the NYSE and values of
foreign futures and options and foreign securities will be determined as of the
earlier closing of such exchanges and securities markets. However, events
affecting the values of such foreign securities may occasionally occur between
the earlier closings of such exchanges and securities markets and the closing of
the NYSE which will not be reflected in the computation of the net asset value
of a Series. If an event materially affecting the value of such foreign
securities occurs during such period, then such securities will be valued at
fair value as determined in good faith by or under the direction of the Board of
Trustees. Where a foreign securities market remains open at the time that a
Series values its portfolio securities, or closing prices of securities from
that market may not be retrieved because of local time differences or other
difficulties in obtaining such prices at that time, last sale prices in such
market at a point in time most practicable to timely valuation of the Series may
be used.

REDEMPTIONS

Under normal circumstances shareholders may redeem their shares at any time
without a fee. The redemption price will be based upon the net asset value per
share next determined after receipt of the redemption request, provided it has
been submitted in the manner described below. The redemption price may be more
or less than the original cost, depending upon the net asset value per share at
the time of redemption.
    
Payment for shares tendered for redemption is made by check within five business
days after tender in proper form, except that the Trust reserves the right to 
suspend the right of redemption, or to postpone the date of payment upon 
redemption beyond five business days, (i) for any period during which the NYSE 
is closed (other than customary weekend and holiday closings) or during which 
trading on the NYSE is restricted, (ii) for any period during which an 
emergency exists as determined by the SEC as a result of which disposal of 
securities owned by a Series is not reasonably practicable or it is not 
reasonably practicable for the Series fairly to determine the value of its net 
assets, or

                                      37
<PAGE>
 
(iii) for such other periods as the SEC may by order permit for the protection
of shareholders of the Series.

Under unusual circumstances, when the Board of Trustees deems it in the best
interest of the Series' shareholders, the Trust may make payment for shares
repurchased or redeemed in whole or in part in securities of the Series taken at
current values. With respect to such redemptions in kind, the Trust has made an
election pursuant to Rule 18f-1 under the Act. This will require the Trust to
redeem in cash at a shareholder's election in any case where the redemption
involves less than $250,000 (or 1% of the Series' net asset value at the
beginning of each 90 day period during which such redemptions are in effect, if
that amount is less than $250,000), during any 90-day period for any one
shareholder. Should payment be made in securities, the redeeming shareholder may
incur brokerage costs in converting such securities to cash.

TAXATION
- --------

Each of the Series has qualified, and intends to continue to qualify each year,
as a regulated investment company under Subchapter M of the Code. In order to so
qualify, a mutual fund must, among other things, (i) derive at least 90% of its
gross income from dividends, interest, payments with respect to certain
securities loans, gains from the sale of securities or foreign currencies, or
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; (ii) distribute at least 90% of its dividend,
interest and certain other taxable income each year; and (iii) at the end of
each fiscal quarter maintain at least 50% of the value of its total assets in
cash, government securities, securities of other regulated investment companies
and other securities of issuers which represent, with respect to each issuer, no
more than 5% of the value of a fund's total assets and 10% of the outstanding
voting securities of such issuer, and with no more than 25% of its assets
invested in the securities (other than those of the government or other
regulated investment companies) of any one issuer or of two or more issuers
which the fund controls and which are engaged in the same, similar or related
trades and businesses.

To the extent each of the Series qualifies for treatment as a regulated
investment company, it will not be subject to federal income tax on income and
net capital gains paid to shareholders in the form of dividends or capital gains
distributions.

An excise tax at the rate of 4% will be imposed on the excess, if any, of each
Series' "required distributions" over actual distributions in any calendar year.
Generally, the "required distribution" is 98% of a Series' ordinary income for
the calendar year plus 98% of its capital gain net income recognized during the
one-year period ending on October 31 plus undistributed amounts from prior
years. The Series intend to make distributions sufficient to avoid imposition of
the excise tax. Distributions declared by the Series during October, November or
December to shareholders of record during such month and paid by January 31 of
the following year will be taxable to shareholders in the calendar year in which
they are declared, rather than the calendar year in which they are received.

Gains or losses attributable to fluctuations in exchange rates which occur
between the time a Series accrues interest or other receivables or accrues
expenses or liabilities denominated in a foreign currency and the time the
Series actually collects such receivables, or pays such liabilities, are
generally treated as ordinary income or loss. Similarly, a portion of the gains
or losses realized on disposition of debt securities denominated in a foreign
currency may also be treated as ordinary gain or loss. These gains, referred to
under the Code as "Section 988" gains or losses, may increase or decrease the
amount of a Series' investment company taxable income to be distributed to its
shareholders, rather than increasing or decreasing the amount of the Series'
capital gains or losses.

When a Series writes a call, or purchases a put option, an amount equal to the
premium received or paid by it is included in the Series' assets and liabilities
as an asset and as an equivalent liability.

In writing a call, the amount of the liability is subsequently "marked-to-
market" to reflect the current market value of the option written. The current
market value of a written option is the last sale price on the principal
Exchange on which such option is traded or, in the absence of a sale, the mean
between the last bid and asked prices. If an option which a Series has written
expires on its stipulated expiration date, the Series recognizes a short-term
capital gain. If a Series enters into a closing purchase transaction with
respect to an option which the Series has written, the Series realizes a short-
term gain (or loss if the cost of the closing transaction exceeds the premium
received when the option was sold) without regard to any unrealized gain or loss
on the underlying security, and the liability related to such option is
extinguished. If a call option which a Series has written is exercised, the
Series realizes a capital gain or loss from the

                                      38
<PAGE>
 
sale of the underlying security and the proceeds from such sale are increased by
the premium originally received.

The premium paid by a Series for the purchase of a put option is recorded in the
Series' assets and liabilities as an investment and subsequently adjusted daily
to the current market value of the option. For example, if the current market
value of the option exceeds the premium paid, the excess would be unrealized
appreciation and, conversely, if the premium exceeds the current market value,
such excess would be unrealized depreciation. The current market value of a
purchased option is the last sale price on the principal Exchange on which such
option is traded or, in the absence of a sale, the mean between the last bid and
asked prices. If an option which a Series has purchased expires on the
stipulated expiration date, the Series realizes a short-term or long-term
capital loss for Federal income tax purposes in the amount of the cost of the
option. If a Series exercises a put option, it realizes a capital gain or loss
(long-term or short-term, depending on the holding period of the underlying
security) from the sale which will be decreased by the premium originally paid.

Accounting for options on certain stock indices will be in accordance with
generally accepted accounting principles. The amount of any realized gain or
loss on closing out such a position will result in a realized gain or loss for
tax purposes. Such options held by a Series at the end of each fiscal year on a
broad-based stock index will be required to be "marked-to-market" for Federal
income tax purposes. Sixty percent of any net gain or loss recognized on such
deemed sales or on any actual sales will be treated as long-term capital gain or
loss and the remainder will be treated as short-term capital gain or loss.
Certain options, futures contracts and options on futures contracts utilized by
the Series are "Section 1256 contracts." Any gains or losses on Section 1256
contracts held by a Series at the end of each taxable year (and on October 31 of
each year for purposes of the 4% excise tax) are "marked-to-market" with the
result that unrealized gains or losses are treated as though they were realized
and the resulting gain or loss is treated as a 60/40 gain or loss. 
        
If there is a constructive sale for federal income tax purposes (e.g., short
sale against the box) of an appreciated financial position, a taxpayer must
recognize gain as if such position were sold, assigned, or otherwise terminated
at its fair market value as of the date of the constructive sale and immediately
repurchased. Shareholders will be subject to federal income taxes on
distributions made by the Series whether received in cash or additional shares
of the Series. Distributions of net investment income and net short-term capital
gains, if any, will be taxable to shareholders as ordinary income. Distributions
of net long-term capital gains, if any, will be taxable to shareholders as long-
term capital gains, without regard to how long a shareholder has held shares of
the Series. A loss on the sale of shares held for six months or less will be
treated as a long-term capital loss to the extent of any long-term capital gain
dividend paid to the shareholder with respect to such shares. Dividends eligible
for designation under the dividends received deduction and paid by a Series may
qualify in part for the 70% dividends received deduction for corporations
provided, however, in respect of any dividend, that those shares have been held
for at least 46 days during the 90-day period that begins 45 days before the
stock becomes ex-dividend with respect to such dividend. The Series will notify
shareholders each year of the amount of dividends and distributions, including
the amount of any distribution of long-term capital gains and the portion of its
dividends which may qualify for the 70% deduction.          
        
        
Each class of shares of a Series will share proportionately in the investment
income and expenses of that Series, except that the respective UBS Investments
Funds class and Brinson Fund-Class N for each Series will incur distribution
fees under their respective 12b-1 plans.     

It is expected that certain dividends and interest received by the Global Funds
and the Non-U.S. Equity Fund will be subject to foreign withholding taxes. If
more than 50% in value of the total assets of a fund at the close of any taxable
year consists of stocks or securities of foreign corporations, such fund may
elect to treat any foreign taxes paid by it as if paid by its shareholders.
These Series will notify shareholders in writing each year whether it has made
the election and the amount of foreign taxes it has elected to have treated as
paid by the shareholders. If a Series makes the election, its shareholders will
be required to include in gross income their proportionate share of the amount
of foreign taxes paid by the Series and will be entitled to claim either a
credit or deduction for their share of the taxes in computing their U.S. federal
income tax subject to certain limitations. No deduction for foreign taxes may be
claimed by shareholders who do not itemize deductions.
    
Generally, a credit for foreign taxes is subject to the limitation that it may
not exceed the shareholder's U.S. tax attributable to his or her total foreign
source taxable income. For this purpose, the source of each Series' income flows
through to its shareholders. Gains from the sale of securities will be treated
as derived from U.S. sources and certain currency fluctuation gains, including
     
                                      39
<PAGE>
 
    
fluctuation gains from foreign currency denominated debt securities, receivables
and payables, will be treated income derived from U.S. sources. The limitation
on the foreign tax credit is applied separately to foreign source passive income
(as defined for purposes of foreign tax credit), such as foreign source passive
income received from the respective Series. Because of changes made by the Code,
shareholders may be unable to claim a credit for the full amount of their
proportionate share of the foreign taxes paid by the Series. Beginning in 1998, 
an individual with $300 or less ($600 or less for joint filers) of foreign tax 
credits is generally exempt from the foreign tax credit limitation and likely 
will not have to file Form 1116 in order to claim a foreign tax credit.

The foregoing is a general and abbreviated summary of the applicable provisions
of the Code and Treasury Regulations currently in effect. For the complete
provisions, reference should be made to the pertinent Code sections and
Regulations. The Code and Regulations are subject to change by legislative or
administrative action at any time and retroactively.

Dividends and distributions also may be subject to state and local taxes.

Shareholders are urged to consult their tax advisers regarding specific
questions as to federal, state and local taxes as well as the application of the
foreign tax credit.

The foregoing discussion relates solely to U.S. federal income tax law. Non-U.S.
investors should consult their tax advisers concerning the tax consequences of
ownership of shares of the Series, including the possibility that distributions
may be subject to a 30% U.S. withholding tax (or a reduced rate of withholding
provided by treaty).

PERFORMANCE CALCULATIONS

       
Performance information for the UBS Investment Funds class of shares, Brinson
Fund-Class N and Brinson Fund-Class I shares of each Series will vary due to the
effect of expense ratios on the performance calculations.     

TOTAL RETURN
- ------------

Current yield and total return quotations used by the Series (and classes
of shares) are based on standardized methods of computing performance mandated
by rules adopted by the SEC. As the following formula indicates, the average
annual total return is determined by multiplying a hypothetical initial purchase
order of $1,000 by the average annual compound rate of return (including capital
appreciation/depreciation and dividends and distributions paid and reinvested)
for the stated period less any fees charged to all shareholder accounts and
annualizing the result. The calculation assumes that all dividends and
distributions are reinvested at the net asset value on the reinvestment dates
during the period. The quotation assumes the account was completely redeemed at
the end of each period and deduction of all applicable charges and fees.
According to the SEC formula:

            P(1+T)/n/=ERV
where:
     P      =    a hypothetical initial payment of $1,000,
     T      =    average annual total return,
     n      =    number of years,
     ERV    =    ending redeemable value of a hypothetical $1,000 payment made
                 at the beginning of the 1, 5 or 10 year periods at the end of
                 the 1, 5 or 10 year periods (or fractional portion thereof).

            
Based upon the foregoing calculations, the average annual total return for the
Brinson Fund-Class I (previously Brinson Fund Class) shares of:     

     (i)   the Global Fund, for the one- and three-year periods ended June 30,
           1998 and the periods August 31, 1992 (commencement of operations)
           through June 30, 1998 was 8.28%, 14.38% and 11.44%, respectively;

     (ii)  the Global Equity Fund, for the one- and three-year periods ended 
           June 30, 1998 and the period January 28, 1994 (commencement of
           operations) through June 30, 1998 was 8.99%, 18.41%, and 12.45%,
           respectively;

     (iii) the Global Bond Fund, for the one- and three-year periods ended June
           30, 1998 and the period July 30, 1993 (commencement of operations)
           through June 30, 1998 was 2.69%, 7.23% and 6.49%, respectively;
 
     (iv)  the U.S. Balanced Fund, for the one-year period ended June 30, 1998
           and the period December 30, 1994 (commencement of operations) through
           June 30, 1998 was 12.19%, 13.72%, and 15.90%, respectively; 

     (v)   the U.S. Equity Fund, for the one- and three-year periods ended June
           30, 1998 and the period February 22, 1994 (commencement of
           operations) through June 30, 1998 was 21.48%, 27.86% and 23.11%,
           respectively;

     (vi)  the U.S. Large Capitalization Equity Fund, for the period April 6, 
           1998 (commencement of operations) through June 30, 1998 was (1.83)%.

    (vii)  the U.S. Bond Fund, for the one-year period ended June 30, 1998 and
           the period August 31, 1995 (commencement of operations)
           through June 30, 1998 was 10.60% and 7.99%, respectively; and

   (viii)  the Non-U.S. Equity Fund, for the one- and three-year periods ended
           June 30, 1998 and the period August 31, 1993 (commencement of
           operations) through June 30, 1998 was 4.78%, 15.91% and 9.03%,
           respectively.     
    
Based upon the foregoing calculations, the average annual total return for the
UBS Investment Funds class of shares of: 
    
     (i)    the Global Fund, for the one-year period ended June 30,
            1998 and the period July 31, 1995 (commencement of operations)
            through June 30, 1998 was 7.60% and 13.30%, respectively; 

     (ii)   the Global Equity Fund, for the one-year period ended June 30, 
            1998 and the period July 31, 1995 (commencement of operations)
            through June 30, 1998 was 8.15% and 16.26%, respectively;

     (iii)  the Global Bond Fund, for the one-year period ended June 30, 
            1998 and the period July 31, 1995 (commencement of operations)
            through June 30, 1998 was 2.28% and 6.36%, respectively; 
         

                                      41

     (iv)   the U.S. Balanced Fund, for the one-year period ended June 30, 1998
            and the period July 31, 1995 (commencement of operations) through
            June 30, 1998 was 11.79% and 13.15%, respectively;

     (v)    the U.S. Equity Fund, for the one-year period ended June
            30, 1998 and the period July 31, 1995 (commencement of operations)
            through June 30, 1998 was 20.80% and 26.66%, respectively;
     
     (vi)   the U.S. Large Capitalization Equity Fund, for the period April 6,
            1998 (commencement of operations) through June 30, 1998 was (2.06)%;

     (vii)  the U.S. Bond Fund, for the one-year period ended June 30, 1998 and
            the period August 31, 1995 (commencement of operations) through June
            30, 1998 was 9.97% and 7.43%, respectively; and

     (viii) the Non-U.S. Equity Fund, for the one-year period ended June 30,
            1998 and the period July 31, 1995 (commencement of operations)
            through June 30, 1998 was 3.90% and 13.19%, respectively.


Based on the foregoing calculations, the average annual total return for the
Brinson Fund-Class N shares of:

     (i)    the Global Fund, for the period June 30, 1997 (commencement of
            operations) through June 30, 1998 was 7.90%;

     (ii)   the Global Equity Fund, for the period June 30, 1997 (commencement
            of operations) through June 30, 1998 was 8.60%;

     (iii)  the Global Bond Fund, for the period June 30, 1997 (commencement of
            operations) through June 30, 1998 was 2.37%;

     (iv)   the U.S. Balanced Fund, for the period June 30, 1997 (commencement
            of operations) through June 30, 1998 was 12.15%;

     (v)    the U.S. Equity Fund, for the period June 30, 1997 (commencement of
            operations) through June 30, 1998 was 21.10%;

     (vi)   the U.S. Large Capitalization Equity Fund, for the period April 6,

YIELD
- -----

As indicated below, current yield is determined by dividing the net investment
income per share earned during the period by the maximum offering price per
share on the last day of the period and annualizing the result. Expenses accrued
for the period include any fees charged to all shareholders during the 30-day
base periods. According to the SEC 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 reimbursements).
     c    =    the average daily number of shares outstanding during the period
               that were entitled to receive dividends.
     d    =    the maximum offering price per share on the last day of the 
               period.

The yield of a Series may be calculated by dividing the net investment income
per share earned by the particular Series during a 30-day (or one month) period
by the net asset value per share on the last day of the period and annualizing
the result on a semi-annual basis. A Series' net investment income per share
earned during the period is based on the average daily number of shares
outstanding during the period entitled to receive dividends and includes
dividends and interest earned during the period minus expenses accrued for the
period, net of reimbursements.

FINANCIAL STATEMENTS
            
The Series' Financial Statements for the fiscal year ended June 30, 1998 and the
Reports of Independent Auditors thereon, which are contained in the Series'
Annual Reports dated June 30, 1998, are incorporated herein by reference.

CORPORATE DEBT RATINGS                                                APPENDIX A

Moody's Investors Service, Inc. describes classifications of corporate bonds as
follows:

     Aaa - Bonds which are rated Aaa are judged to be of the best quality. They
     carry the smallest degree of investment risk and are generally referred to
     as "gilt-edged". Interest payments are protected by a large or by an
     exceptionally stable margin and principal is secure. While the various
     protective elements are likely to change, such changes as can be visualized
     are most unlikely to impair the fundamentally strong position of such
     issues.

     Aa - Bonds which are rated Aa are judged to be of high-quality by all
     standards. Together with the Aaa group they comprise what are generally
     known as high-grade. They are rated lower than the best bonds because
     margins of protection may not be as large as in Aaa securities or
     fluctuation of protective elements may be of greater amplitude or there may
     be other elements present which make the long-term risks appear somewhat
     larger than in Aaa securities.

     A - Bonds which are rated A possess many favorable investment attributes
     and are to be considered as upper medium-grade obligations. Factors giving
     security to principal and interest are considered adequate, but elements
     may be present which suggest a susceptibility to impairment sometime in the
     future.

     Baa - Bonds which are rated Baa are considered as medium-grade obligations,
     (i.e., they are neither highly protected nor poorly secured). Interest
     payments and principal security appear adequate for the present but certain
     protective elements may be lacking or may be characteristically unreliable
     over any great length of time. Such bonds lack outstanding investment
     characteristics and in fact have speculative characteristics as well.

     Ba - Bonds which are rated Ba are judged to have speculative elements;
     their future cannot be considered as well-assured. Often the protection of
     interest and principal payments may be very moderate and thereby not well
     safeguarded during both good and bad times over the future. Uncertainty of
     position characterizes bonds in this class.

     B - Bonds which are rated B generally lack characteristics of the desirable
     investment. Assurance of interest and principal payments or of maintenance
     of other terms of the contract over any long period of time may be small.

     Caa - Bonds which are rated Caa are of poor standing. Such issues may be in
     default or there may be present elements of danger with respect to
     principal or interest.

     Ca - Bonds which are rated Ca represent obligations which are speculative
     in a high degree. Such issues are often in default or have other marked
     shortcomings.

     C - Bonds which are rated C are the lowest rated class of bonds and issues
     so rated can be regarded as having extremely poor prospects of ever
     attaining any real investment standing.

Moody's also supplies numerical indicators 1, 2, and 3 to rating categories. The
modifier 1 indicates the security is in the higher end of its rating category;
the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a
ranking toward the lower end of the category.

Standard & Poor's Ratings Group describes classifications of corporate bonds as
follows:

     AAA - This is the highest rating assigned by Standard & Poor's Ratings
     Group to a debt obligation and indicates an extremely strong capacity to
     pay principal and interest.

     AA - Bonds rated AA also qualify as high-quality debt obligations. Capacity
     to pay principal and interest is very strong and in the majority of
     instances they differ from the AAA issues only in small degree.

     A - Bonds rated A have a strong capacity to pay principal and interest,
     although they are somewhat more

     susceptible to the adverse effects of changes in circumstances and economic
     conditions.

     BBB - Bonds rated BBB are regarded as having an adequate capacity to pay
     principal and interest. Whereas they normally exhibit adequate protection
     parameters, adverse economic conditions or changing circumstances are more
     likely to lead to a weakened capacity to pay principal and interest for
     bonds in this category than for bonds in the A category.

     BB - Debt rated BB has less near-term vulnerability to default than other
     speculative grade debt. However, it faces major ongoing uncertainties or
     exposure to adverse business, financial or economic conditions which could
     lend to inadequate capacity to meet timely interest and principal payments.

     B - Debt rated B has a greater vulnerability to default but presently has
     the capacity to meet interest payments and principal repayments. Adverse
     business, financial or economic conditions would likely impair capacity or
     willingness to pay interest and repay principal.

     CCC - Debt rated CCC has a current identifiable vulnerability to default,
     and is dependent upon favorable business, financial and economic conditions
     to meet timely payments of interest and repayment of principal. In the
     event of adverse business, financial or economic conditions, it is not
     likely to have the capacity to pay interest or repay principal.

     CC - The rating CC is typically applied to debt subordinated to senior debt
     which is assigned an actual or implied CCC rating.

     C - The rating C is typically applied to debt subordinated to senior debt
     which is assigned an actual or implied CCC rating.

     CI - The rating CI is reserved for income bonds on which no interest is
     being paid.

     D - Debt rated D is in default, or is expected to default upon maturity or
     payment date.

     Plus (+) or minus (-): The ratings from AA to CCC may be modified by the
     addition of a plus or minus sign to show relative standing within the major
     rating categories.
