General Investment Management Approach
 
 Goldman Sachs Asset Management, a separate operating division of Goldman,
 Sachs & Co. ("Goldman Sachs"), serves as investment adviser to the Short
 Duration Tax-Free, Government Income, Municipal Income, Core Fixed Income
 and High Yield Funds. Goldman Sachs Funds Management, L.P. serves as invest-
 ment adviser to the Adjustable Rate Government and Short Duration Government
 Funds. Goldman Sachs Asset Management International serves as investment
 adviser to the Global Income Fund. Goldman Sachs Asset Management, Goldman
 Sachs Funds Management, L.P., and Goldman Sachs Asset Management Interna-
 tional are each referred to in this Prospectus as the "Investment Adviser."
 
 Goldman Sachs' Fixed Income Investing Philosophy:
 Active Management Within a Risk-Managed Framework
 The Investment Adviser employs a disciplined, multi-step process to evaluate
 potential investments:
 1. Sector Allocation--The Investment Adviser assesses the relative value of
 different investment sectors (such as U.S. corporate, asset-backed and mort-
 gage-backed securities) to create investment strategies that meet each
 Fund's objectives.
 2. Security Selection--In selecting securities for each Fund, the Investment
 Adviser draws on the extensive resources of Goldman Sachs, including fixed-
 income research professionals.
 3. Yield Curve Strategies--The Investment Adviser adjusts the term structure
 of the Funds based on its expectations of changes in the shape of the yield
 curve while closely controlling the overall duration of the Fund.
 
 The Investment Adviser de-emphasizes interest rate predictions as a means of
 generating incremental return. Instead, the Investment Adviser seeks to add
 value through the selection of particular securities and investment sector
 allocation as described above.
 
 With every fixed-income portfolio, the Investment Adviser applies a team
 approach that emphasizes risk management and capitalizes on Goldman Sachs'
 extensive research capabilities.

<PAGE>
 
 
 
 Each of the Funds described in this Prospectus has a target duration. A
 Fund's duration approximates its price sensitivity to changes in interest
 rates. Maturity measures the time until final payment is due; it takes no
 account of the pattern of a security's cash flows over time. In computing
 portfolio duration, a Fund will estimate the duration of obligations that
 are subject to prepayment or redemption by the issuer, taking into account
 the influence of interest rates on prepayments and coupon flows. This method
 of computing duration is known as "option-adjusted" duration. A Fund will
 not be limited as to its maximum weighted average portfolio maturity or the
 maximum stated maturity with respect to individual securities unless other-
 wise noted.
 
 Each Fund also has credit rating requirements for the securities it buys. A
 Fund will deem a security to have met its minimum credit rating requirement
 if the security has the required rating at the time of purchase from at
 least one nationally recognized statistical rating organization ("NRSRO")
 even though it has been rated below the minimum rating by one or more other
 NRSROs. Unrated securities may be purchased by the Funds if they are deter-
 mined by the Investment Adviser to be of comparable quality. If a security
 satisfies a Fund's minimum rating requirement at the time of purchase and is
 subsequently downgraded below such rating, the Fund will not be required to
 dispose of such security. If a downgrade occurs, the Investment Adviser will
 consider what action, including the sale of such security, is in the best
 interests of a Fund and its shareholders.

 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal circumstances, at least 65% of its total
 assets in securities issued or guaranteed by the U.S. government, its agen-
 cies, instrumentalities or sponsored enterprises ("U.S. Government Securi-
 ties") that are adjustable rate mortgage pass-through securities and other

Goldman Sachs Short Duration Tax-Free Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high level of current income, consistent with relatively
 low volatility of principal, that is exempt from regular federal income tax.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal conditions, at least 80% of its net assets in
 fixed-income securities issued by or on behalf of states, territories and
 possessions of the United States (including the District of Columbia) and
 the political subdivisions, agencies and instrumentalities thereof ("Munici-
 pal Securities"), the interest on which is exempt from regular federal
 income tax (i.e., excluded from gross income for federal income tax purpos-
 es), and is not a tax preference item under the federal alternative minimum
 tax. Under normal circumstances, the Fund's investments in private activity
 bonds and taxable investments will not exceed, in the aggregate, 20% of the
 Fund's net assets. The interest from private activity bonds (including the
 Fund's distributions of such interest) may be a preference item for purposes
 of the federal alternative minimum tax. 100% of the Fund's portfolio will be
 invested in U.S. dollar-denominated securities.

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
Goldman Sachs Municipal Income Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high level of current income that is exempt from regular
 federal income tax, consistent with preservation of capital.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal circumstances, at least 80% of its net assets
 in Municipal Securities, the interest on which is exempt from regular fed-
 eral income tax (i.e., excluded from gross income for federal income tax
 purposes). The Fund may invest up to 100% of its net assets in private
 activity bonds, the interest from which (including the Fund's distributions
 of such interest) may be a preference item for purposes of the federal
 alternative minimum tax. 100% of the Fund's portfolio will be invested in
 U.S. dollar-denominated securities.
 
 Duration (under normal interest rate conditions):
 Target = Lehman Brothers 15-Year Municipal Bond Index plus or minus one year
 Maximum = 12 years
 
 Expected Approximate Interest Rate Sensitivity: 15-year municipal bond

Goldman Sachs Core Fixed Income Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a total return consisting of capital appreciation and income
 that exceeds the total return of the Lehman Brothers Aggregate Bond Index
 (the "Index").
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal circumstances, at least 65% of its total
 assets in fixed-income securities, including U.S. Government Securities,
 corporate debt securities, Mortgage-Backed Securities and asset-backed secu-
 rities. The Fund may also invest in custodial receipts, Municipal Securities
 and convertible securities. The Fund's investments in non-U.S. dollar denom-
 inated obligations will not exceed 25% of its total assets at the time of
 investment, of which 10% may be invested in obligations of issuers in coun-
 tries with emerging markets or economies ("emerging countries"). In pursuing
 its investment objective, the Fund uses the Index as its performance bench-
 mark, but the Fund will not attempt to replicate the Index. The Fund may,
 therefore, invest in securities that are not included in the Index.
 
 Duration (under normal interest rate conditions):
 Target = Lehman Brothers Aggregate Bond Index plus or minus one year
 Maximum = 6 years
 
 Expected Approximate Interest Rate Sensitivity: 5-year U.S. Treasury note
 
 Credit Quality:
 Minimum = BBB or Baa; Minimum for non-U.S. dollar denominated securities =

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
Goldman Sachs Global Income Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high total return, emphasizing current income, and, to a
 lesser extent, providing opportunities for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests primarily in a portfolio of high quality fixed-income secu-
 rities of U.S. and foreign issuers and enters into transactions in foreign
 currencies. Under normal market conditions, the Fund will:
 .Have at least 30% of its total assets, after considering the effect of cur-
  rency positions, denominated in U.S. dollars
 .Invest in securities of issuers in at least three countries
 .Seek to meet its investment objective by pursuing investment opportunities
  in foreign and domestic fixed-income securities markets and by engaging in
  currency transactions to seek to enhance returns and to seek to hedge its
  portfolio against currency exchange rate fluctuations
 
 The Fund may invest more than 25% of its total assets in the securities of
 corporate and governmental issuers located in each of Canada, Germany, Japan
 and the United Kingdom as well as in the securities of U.S. issuers. Not
 more than 25% of the Fund's total assets will be invested in securities of
 issuers in any other single foreign country. The Fund may also invest up to
 10% of its total assets in issuers in emerging countries.
 
 The fixed-income securities in which the Fund may invest include:
 .U.S. Government Securities and custodial receipts therefor
 .Securities issued or guaranteed by a foreign government or any of its
  political subdivisions, authorities, agencies, instrumentalities or by
  supranational entities
 .Corporate debt securities
 .Certificates of deposit and bankers' acceptances issued or guaranteed by,
  or time deposits maintained at, U.S. or foreign banks (and their branches
  wherever located) having total assets of more than $1 billion
 .Commercial paper
 .Mortgage-Backed Securities and asset-backed securities
 
 The Global Income Fund is "non-diversified" under the Investment Company Act
 of 1940 (the "Act"), and may invest more of its assets in fewer issuers than
 
                                                                               9
<PAGE>
 
Goldman Sachs Global Income Fund continued
 
 "diversified" mutual funds. Therefore, the Global Income Fund may be more
 susceptible to adverse developments affecting any single issuer held in its
 portfolio, and may be more susceptible to greater losses because of these
 developments.
 
 Duration (under normal interest rate conditions):
 Target = J.P. Morgan Global Government Bond Index (hedged) plus or minus
 2.5 years
 Maximum = 7.5 years
 
 Expected Approximate Interest Rate Sensitivity: 6-year government bond
 
 Credit Quality:

Goldman Sachs High Yield Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high level of current income and may also consider the
 potential for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal circumstances, at least 65% of its total
 assets in high yield, fixed-income securities rated, at the time of invest-
 ment, below investment grade. Non-investment grade securities are securities
 rated BB, Ba or below by a NRSRO, or, if unrated, determined by the Invest-
 ment Adviser to be of comparable quality. The Fund may invest in all types
 of fixed-income securities, including:
 .Senior and subordinated corporate debt obligations (such as bonds, deben-
  tures, notes and commercial paper)
 .Convertible and non-convertible corporate debt obligations
 .Loan participations
 .Custodial receipts
 .Municipal Securities
 .Preferred stock
 
 The Fund may invest up to 25% of its total assets in obligations of domestic
 and foreign issuers (including securities of issuers located in emerging
 countries) which are denominated in currencies other than the U.S. dollar.
 
 Under normal market conditions, the Fund may invest up to 35% of its total
 assets in investment grade fixed-income securities, including U.S. Govern-
 ment Securities. The Fund may also invest in common stocks, warrants, rights
 and other equity securities, but will generally hold such equity investments
 only when debt or preferred stock of the issuer of such equity securities is
 held by the Fund.
 
 Duration (under normal interest rate conditions):
 Target = Lehman Brothers High Yield Bond Index plus or minus 2.5 years
 Maximum = 7.5 years
 
 Expected Approximate Interest Rate Sensitivity: 6-year U.S. Treasury note
 
                                                                              11
<PAGE>
 
Goldman Sachs High Yield Fund continued
 
 
 Credit Quality:
 At least 65% of total assets = BB or Ba or lower at the time of investment
 or, if unrated, determined by the Investment Adviser to be of comparable
 quality
 
 Non-investment grade fixed income securities (commonly known as "junk
 bonds") tend to offer higher yields than higher rated securities with simi-
 lar maturities. Non-investment grade fixed income securities are, however,
 considered speculative and generally involve greater price volatility and
 greater risk of loss of principal and interest than higher rated securities.
 The Fund may purchase the securities of issuers that are in default.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other governmental agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

All Funds:
 
 .Interest Rate Risk--The risk that when interest rates increase, fixed income
 securities held by a Fund will decline in value. Long-term fixed-income
 securities will normally have more price volatility because of this risk than
 short-term securities.
 .Credit/Default Risk--The risk that an issuer of fixed-income securities held
 by a Fund (which may have low credit ratings) may default on its obligation to
 pay interest and repay principal.
 .Call Risk--The risk that an issuer will exercise its right to pay principal on
 an obligation held by a Fund (such as a Mortgage-Backed Security) earlier than
 expected. This may happen when there is a decline in interest rates. Under
 these circumstances, a Fund may be unable to recoup all of its initial
 investment and will also suffer from having to reinvest in lower yielding
 securities.
 .Extension Risk--The risk that an issuer will exercise its right to pay
 principal on an obligation held by a Fund (such as a Mortgage-Backed Security)
 later than expected. This may happen when there is a rise in interest rates.
 Under these circumstances, the value of the obligation will decrease, and a
 Fund will also suffer from the inability to invest in higher yielding
 securities.
 .Derivatives Risk--The risk that loss may result from a Fund's investments in
 options, futures, swaps, structured securities and other derivative
 investments. These instruments may be leveraged so that small changes may
 produce disproportionate losses to a Fund.
 .U.S. Government Securities Risk--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 .Market Risk--The risk that the value of the securities in which a Fund invests
 may go up or down in response to the prospects of individual companies and/or
 general economic conditions. Price changes may be temporary or last for
 extended periods.
 .Management Risk--The risk that a strategy used by the Investment Adviser may
 fail to produce the intended results.
 .Liquidity Risk--The risk that a Fund will not be able to pay redemption
 proceeds within the time period stated in this Prospectus, because of unusual
 market conditions, an unusually high volume of redemption requests, or other
 reasons. Funds that invest in non-investment grade fixed income securities or
 emerging country issuers will be especially subject to the risk that during
 certain periods the liquidity of particular issuers or industries, or all
 securities within these investment categories, will shrink or disappear
 suddenly and without warning as a result of adverse economic, market or
 political events, or adverse investor perceptions whether or not accurate.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 .Other Risks--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Specific Funds:
 
 .Non-Diversification Risk--The Global Income Fund is non-diversified. The
 Global Income Fund may invest more than 25% of its total assets in the securi-
 ties of corporate and governmental issuers located in each of Canada, Germany,
 Japan and the United Kingdom, as well as in the securities of U.S. issuers.
 Concentration of the Fund's investments in such issuers will subject the Fund,
 to a greater extent than if investments were less concentrated, to losses
 arising from adverse developments affecting those issuers or countries.
 .Foreign Risks--The Core Fixed Income, Global Income and High Yield Funds will
 be subject to risks of loss with respect to their foreign investments that are
 not typically associated with domestic issuers. Loss may result because of
 less foreign government regulation, less public information and less economic,
 political and social stability. Loss may also result from the imposition of
 exchange controls, confiscations and other government restrictions. The Funds
 will also be subject to the risk of negative foreign currency rate fluctua-
 tions. Foreign risks will normally be greatest when a Fund invests in issuers
 located in emerging countries.
 .Emerging Markets Risk--The Core Fixed Income, Global Income and High Yield
 Funds may invest in emerging countries. The securities markets of Asian, Latin
 American, Eastern European, African and other emerging countries are less liq-
 uid, are especially subject to greater price volatility, have smaller market
 capitalizations, have less government regulation and are not subject to as
 extensive and frequent accounting, financial and other reporting requirements
 as the securities markets of more developed countries. Further, investment in
 equity securities of issuers located in Russia and certain other emerging
 countries involves risk of loss resulting from problems in share registration
 and custody and substantial economic and political disruptions. These risks
 are not normally associated with investment in more developed countries.
 ."Junk Bond" Risk--The High Yield Fund will invest in non-investment grade
 fixed-income securities (commonly known as "junk bonds") that are considered
 predominantly speculative by traditional investment standards. Non-investment
 grade fixed-income securities and unrated securities of comparable credit
 quality are subject to the increased risk of an issuer's inability to meet
 principal and interest obligations. These securities may be subject to greater
 price volatility due to such factors as specific corporate developments,
 interest rate sensitivity, negative perceptions of the junk bond markets
 generally and less secondary market liquidity.
 
                                                                              21
<PAGE>
 
 
 .Tax Risk--The Short Duration Tax-Free and Municipal Income Funds may be more
 adversely impacted by changes in tax rates and policies than the other Funds.
 Because interest income from Municipal Securities is normally not subject to
 regular federal income taxation, the attractiveness of Municipal Securities in
 relation to other investment alternatives is affected by changes in federal
 income tax rates applicable to, or the continuing federal income tax-exempt
 status of, such interest income. Any proposed or actual changes in such rates
 or exempt status, therefore, can significantly affect the demand for and sup-
 ply, liquidity and marketability of Municipal Securities. This could in turn
 affect a Fund's ability to acquire and dispose of Municipal Securities at
 desirable yield and price levels.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Insti-
 tutional Shares from year to year; and (b) how the average annual returns of
 the Fund's Institutional Shares compare to those of broad-based securities
 market indices. The bar chart and table assume reinvestment of dividends and
 distributions. A Fund's past performance is not necessarily an indication of
 how the Fund will perform in the future. Performance reflects expense limi-
 tations in effect. If expense limitations were not in place, a Fund's per-
 formance would have been reduced.

Example
 
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the waivers and expense limitations) with the cost of investing
in other mutual funds. The Example assumes that you invest $10,000 in Institu-
tional Shares of a Fund for the time periods indicated and then redeem all of
your Institutional Shares at the end of those periods. The Example also assumes
that your investment has a 5% return each year and that a Fund's operating
expenses remain the same. Although your actual costs may be higher or lower,
based on these assumptions your costs would be:

 GSAM is a separate operating division of Goldman Sachs, which registered as
 an investment adviser in 1981. GSFM, a registered investment adviser since
 1990, is a Delaware limited partnership which is an affiliate of Goldman
 Sachs. GSAMI, a member of the Investment Management Regulatory Organization
 Limited since 1990 and a registered investment adviser since 1991, is an
 affiliate of Goldman Sachs. As of December 31, 1998, GSAM, GSFM and GSAMI,

 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser makes the investment decisions
 for the Funds and places purchase and sale orders for the Funds' portfolio
 transactions in U.S. and foreign markets. As permitted by applicable law,
 these orders may be directed to any brokers, including Goldman Sachs and its
 affiliates. While the Investment Adviser is ultimately responsible for the
 management of the Funds, it is able to draw upon the research and expertise
 of its asset management affiliates for portfolio decisions and management
 with respect to certain portfolio securities. In addition, the Investment
 Adviser has access to the research and certain proprietary technical models
 developed by Goldman Sachs, and will apply quantitative and qualitative
 analysis in determining the appropriate allocations among categories of
 issuers and types of securities.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to a Fund or limit a Fund's investment activities. Goldman Sachs and its
 affiliates engage in proprietary trading and advise accounts and funds which
 have investment objectives similar to those of the Funds and/or which engage
 in and compete for transactions in the same types of securities, currencies
 and instruments as the Funds. Goldman Sachs and its affiliates will not have
 any obligation to make available any information regarding their proprietary
 activities or strategies, or the activities or strategies used for other
 accounts managed by them, for the benefit of the management of the Funds.
 The results of a Fund's investment activities, therefore, may differ from
 those of Goldman Sachs and its affiliates, and it is possible that a Fund
 could sustain losses during periods in which Goldman Sachs and its affili-
 ates and other accounts achieve significant profits on their trading for
 proprietary or other accounts. In addition, the Funds may, from time to
 time, enter into transactions in which other clients of Goldman Sachs have
 an adverse interest. A Fund's activities may be limited because of regula-
 tory restrictions applicable to Goldman Sachs and its affiliates, and/or
 their internal policies designed to comply with such restrictions.
 
                                                                              41

 YEAR 2000
 
 
Many computer systems were designed using only two digits to signify the year
(for example, "98" for "1998"). On January 1, 2000, if these computer systems
are not corrected, they may incorrectly interpret "00" as the year "1900"
rather than the year "2000," leading to computer shutdowns or errors (commonly
known as the "Year 2000 Problem"). To the extent these systems conduct forward-
looking calculations, these computer problems may occur prior to January 1,
2000. Like other investment companies and financial and business organizations,
the Funds could be adversely affected in their ability to process securities
trades, price securities, provide shareholder account services and otherwise
conduct normal business operations if the Investment Adviser or other Fund
service providers do not adequately address this problem in a timely manner.
 
In order to address the Year 2000 Problem, the Investment Adviser has taken the
following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
Currently, the Investment Adviser does not anticipate that the transition to
the 21st century will have any material impact on its ability to continue to
service the Funds at current levels.
 
In addition, the Investment Adviser has undertaken measures to appropriately
take into account available information concerning the Year 2000 preparedness
of the issuers of securities held by the Funds. The Investment Adviser may
obtain such Year 2000 information from various sources which the Investment
Adviser believes to be reliable, including the issuers' public regulatory fil-
ings. However, the Investment Adviser is not in a position to verify the accu-
racy or completeness of such information.
 
At this time, however, no assurance can be given that the actions taken by the
Investment Adviser and the Funds' other service providers will be sufficient to
avoid any adverse effect on the Funds due to the Year 2000 Problem.

Dividends
 
Over the course of the fiscal year, dividends accrued and paid will constitute
all or substantially all of the Funds' net investment income. The Funds also
intend that all net realized capital gains (after taking into account any
available capital loss carryovers) will be declared as a dividend at least
annually. You may choose to have dividends paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 .Shares of the same or an equivalent class of another Goldman Sachs Fund.
 Special restrictions may apply for certain ILA Portfolios. See the Additional
 Statement.
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time before the record date for a
particular dividend or distribution. If you do not indicate any choice, your
dividends and distributions will be reinvested automatically in the applicable
Fund. If cash dividends are elected with respect to the Fund's monthly net
investment income dividends, then cash dividends must also be elected with
respect to the non-long-term capital gains component, if any, of the Fund's
annual dividend.
 
The election to reinvest dividends and distributions in additional shares will
not affect the tax treatment of such dividends and distributions, which will be
treated as received by you and then used to purchase the shares.
 
Dividends from net investment income and distributions from capital gains are
declared and paid as follows:

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Institutional
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Institutional Shares Of The Funds?
 You may purchase Institutional Shares on any business day at their net asset
 value ("NAV") next determined after receipt of an order. No sales load is
 charged. You should place an order with Goldman Sachs at 1-800-621-2550 and
 either:
 .Wire federal funds to The Northern Trust Company ("Northern"), as
  subcustodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian) on the next business day; or
 .Initiate an Automated Clearing House Network ("ACH") transfer to Northern;
  or
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds--(Name
  of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago, IL
  60606-6372. The Fund will not accept a check drawn on a foreign bank or a
  third-party check.
 
 In order to make an initial investment in a Fund, you must furnish to the
 Fund or Goldman Sachs the Account Application attached to this Prospectus.
 Purchases of Institutional Shares must be settled within three business days
 of receipt of a complete purchase order.

 How Do I Purchase Shares Through A Financial Institution?
 Certain institutions (including banks, trust companies, brokers and invest-
 ment advisers) that provide recordkeeping, reporting and processing services
 to their customers may be authorized to accept, on behalf of Goldman Sachs
 Trust (the "Trust"), purchase, redemption and exchange orders placed by or
 on behalf of their customers and may designate other intermediaries to
 accept such orders, if approved by the Trust. In these cases:
 .A Fund will be deemed to have received an order in proper form when the
   order is accepted by the authorized institution or intermediary on a busi-
   ness day, and the order will be priced at the Fund's NAV next determined
   after such acceptance.
 .Authorized institutions or intermediaries will be responsible for transmit-
   ting accepted orders and payments to the Trust within the time period
   agreed upon by them.
 
 You should contact your institution or intermediary directly to learn
 whether it is authorized to accept orders for the Trust.
 
 These institutions may receive payments from the Funds or Goldman Sachs for
 the services provided by them with respect to the Funds' Institutional
 Shares. These payments may be in addition to other payments borne by the
 Funds.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to certain institutions and other persons in
 connection with the sale, distribution and/or servicing of shares of the
 Funds and other Goldman Sachs Funds. Subject to applicable NASD regulations,
 the Investment Adviser, Distributor and/or their affiliates may also con-
 tribute to various cash and non-cash incentive arrangements to promote the
 sale of shares. This additional compensation can vary among such institu-
 tions depending upon such factors as the amounts their customers have
 invested (or may invest) in particular Goldman Sachs Funds, the particular
 program involved, or the amount of reimbursable expenses. Additional compen-
 sation based on sales may, but is currently not expected to, exceed 0.50%
 (annualized) of the amount invested.
 
 In addition to Institutional Shares, each Fund also offers other classes of
 shares to investors. These other share classes are subject to different fees
 and expenses (which affect performance), have different minimum investment
 requirements and are entitled to different services than Institutional
 Shares. Information regarding these other share classes may be obtained from
 your sales representative or from Goldman Sachs by calling the number on the
 back cover of this Prospectus.

 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Modify or waive the minimum investment amounts.
 .Reject or restrict any purchase or exchange orders by a particular pur-
  chaser (or group of related purchasers). This may occur, for example, when
  a pattern of frequent purchases, sales or exchanges of Institutional Shares
  of a Fund is evident, or if purchases, sales or exchanges are, or a subse-
  quent abrupt redemption might be, of a size that would disrupt management
  of a Fund.
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Institutional
 Shares is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _______________________________
                 Number of Outstanding Shares of the Class
 
 The Funds' investments are valued based on market quotations, which may be
 furnished by a pricing service or provided by securities dealers. If accu-
 rate quotations are not readily available, the fair value of the Funds'
 investments may be determined based on yield equivalents, a pricing matrix
 or other sources, under valuation procedures established by the Trustees.
 Debt obligations with a remaining maturity of 60 days or less are valued at
 amortized cost.
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). This occurs after the determination, if
  any, of income declared as a dividend (except in the case of the Global
  Income Fund). Fund shares will not be priced on any day the New York Stock
  Exchange is closed.
 .When you buy shares, you pay the NAV next calculated after the Funds
  receive your order in proper form.
 .When you sell shares, you receive the NAV next calculated after the Funds
  receive your order in proper form.
 
 Note: The time at which transactions and shares are priced and the time by
 which orders must be received may be changed in case of an emergency or if
 regular trading on the New York Stock Exchange is stopped at a time other
 than 4:00 p.m. New York time.
 
                                                                              47
<PAGE>
 
 
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 When Will Shares Be Issued And Dividends Begin To Be Paid?
 Global Income Fund: If a purchase order is received in proper form before
 the Fund's NAV is determined, shares will be issued the same day and will be
 entitled to any dividend declared which have a record date on or after such
 purchase date.
 
 For all other Funds:
 .Shares Purchased by Federal Funds Wire or ACH Transfer:
  .If a purchase order in proper form specifies a settlement date and is
   received before the Fund's NAV is determined that day, shares will be
   issued and dividends will begin to accrue on the purchased shares on the
   later of (i) the business day after the purchase order is received; or
   (ii) the day that the federal funds wire or ACH transfer is received by
   State Street.
  .If a purchase order in proper form does not specify a settlement date,
   shares will be issued and dividends will begin to accrue on the business
   day after payment is received.
 
 .Shares Purchased By Check or Federal Reserve Draft:
  .If a purchase order in proper form specifies a settlement date and is
   received before the Fund's NAV is determined that day, shares will be
   issued and dividends will begin to accrue on the business day after pay-
   ment is received.
  .If a purchase order in proper form does not specify a settlement date,
   shares will be issued and dividends will begin to accrue on the business
   day after payment is received.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Institutional Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. Generally, each Fund will redeem its Institu-
 tional Shares upon request on any business day at their NAV next determined
 after receipt of such request in proper form. You may request that redemp-
 tion proceeds be sent to you by check or by wire (if the wire instructions
 are on record). Redemptions may be requested in writing or by telephone.

 -----------------------------------------------------------------------
</TABLE>
 Certain institutions and intermediaries are authorized to accept redemption
 requests on behalf of the Funds as described under "How Do I Purchase Shares
 Through A Financial Institution?"
 
 What Is A Signature Guarantee?
 A signature guarantee is designed to protect you, the Funds and Goldman
 Sachs from fraud. You may obtain a signature guarantee from a bank, securi-
 ties broker or dealer, credit union having the authority to issue signature
 guarantees, savings and loan association, building and loan association,
 cooperative bank, federal savings bank or association, national securities
 exchange, registered securities association or clearing agency, provided
 that such institution satisfies the standards established by Goldman Sachs.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 
 .All telephone requests are recorded.
 
                                                                              49
<PAGE>
 
 
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request will be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
 How Are Redemption Proceeds Paid?
 By Wire: You may arrange for your redemption proceeds to be wired as federal
 funds to the bank account designated in your Account Application. The fol-
 lowing general policies govern wiring redemption proceeds:
 .Redemption proceeds will normally be wired on the next business day in fed-
  eral funds (for a total of one business day delay), but may be paid up to
  three business days following receipt of a properly executed wire transfer
  redemption request. If you are selling shares you recently paid for by
  check, the Fund will pay you when your check has cleared, which may take up
  to 15 days. If the Federal Reserve Bank is closed on the day that the
  redemption proceeds would ordinarily be wired, wiring the redemption pro-
  ceeds may be delayed one additional business day.
 .To change the bank designated on your Account Application, you must send
  written instructions signed by an authorized person designated on the
  Account Application to the Transfer Agent.
 .Neither the Trust, Goldman Sachs nor any other institution assumes any
  responsibility for the performance of your bank or any intermediaries in
  the transfer process. If a problem with such performance arises, you should
  deal directly with your bank or any such intermediaries.
 
 By Check: You may elect in writing to receive your redemption proceeds by
 check. Redemption proceeds paid by check will normally be mailed to the
 address of record within three business days of a properly executed redemp-
 tion request. If you are selling shares you recently paid for by check, the
 Fund will pay you when your check has cleared, which may take up to 15 days.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Institutional Shares of each Fund (other than the Global Income Fund) earn
  dividends declared on the day the shares are redeemed.

 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Institutions (including banks, trust companies, brokers and investment
  advisers) are responsible for the timely transmittal of redemption requests
  by their customers to the Transfer Agent. In order to facilitate the timely
  transmittal of redemption requests, these institutions may set times by
  which they must receive redemption requests. These institutions may also
  require additional documentation from you.
 
 The Trust reserves the right to:
 .Redeem your shares if your account balance falls below $50 as a result of
  earlier redemptions. The Funds will not redeem your shares on this basis if
  the value of your account falls below the minimum account balance solely as
  a result of market conditions. The Fund will give you 60 days' prior writ-
  ten notice to allow you to purchase sufficient additional shares of the
  Fund in order to avoid such redemption.
 .Redeem your shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange Institutional Shares of a Fund at NAV for Institutional
 Shares of any other Goldman Sachs Fund. The exchange privilege may be mate-
 rially modified or withdrawn at any time upon 60 days' written notice to
 you.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types of Reports Will I Be Sent Regarding Investments in Institutional
 Shares?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-621-2550. You will also be provided with a
 printed confirmation for each transaction in your account and an individual
 monthly account statement (quarterly in the case of the Global Income Fund).
 A year-to-date statement for your account will be provided upon request made
 to Goldman Sachs. The Funds do not generally provide sub-accounting servic-
 es.

Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Except for exempt-interest dividends paid by the Short Duration Tax-Free and
 Municipal Income Funds as described below, Fund distributions are taxable to
 you as ordinary income (unless your investment is in an IRA or other tax-
 advantaged account) to the extent they are attributable to the Fund's net
 investment income, certain net realized foreign exchange gains, and net
 short-term capital gains. They are taxable as long-term capital gain to the
 extent they are attributable to the Fund's excess of net long-term capital
 gains over net short-term capital losses. The tax status of any distribution
 is the same regardless of how long you have been in the Fund and whether you
 reinvest in additional shares or take the distributions as cash. Certain
 distributions paid by a Fund in January of a given year may be taxable to
 shareholders as if received the prior December 31. The tax status and
 amounts of distribution for each calendar year will be detailed in your
 annual tax statement from the Fund.
 
 At any time, a portion of a Fund's NAV per share may be represented by
 undistributed income or realized or unrealized appreciation of the Fund's
 portfolio securities. Therefore, subsequent distributions on a Fund's shares
 may be taxable to you, even if the NAV of your shares is, as a result,
 reduced below the cost of those shares and the distributions represent a
 return of your purchase price.
 
 The Core Fixed Income, Global Income and High Yield Funds may be subject to
 foreign withholding or other foreign taxes on income or gain from certain
 foreign securities. In general, the Funds may deduct these taxes in comput-
 ing their taxable income. As an alternative, the Global Income Fund (but not
 the other Funds) may make an election to treat a proportionate amount of
 such taxes as constituting a distribution to you, which would allow you
 either to (1) credit such proportionate amount of taxes against your U.S.
 federal income tax liability or (2) take such amount as an itemized deduc-
 tion.
 
 The Short Duration Tax-Free and Municipal Income Funds expect to distribute
 "exempt-interest dividends." These dividends will be exempt income for fed-
 eral income tax purposes. However, distributions, if any, derived from net
 long-term capital gains of the Short Duration Tax-Free and Municipal Income
 Funds will generally be taxable to you as long-term capital gains. Distribu-
 tions, if any, derived from taxable interest income, net short-term capital
 gains
 
                                                                              53
<PAGE>
 
 
 and certain net realized foreign exchange gains will be taxable to you as
 ordinary income.
 
 Interest on indebtedness incurred by you to purchase or carry shares of the
 Short Duration Tax-Free and Municipal Income Funds generally will not be
 deductible for federal income tax purposes.
 
 You should note that exempt-interest dividends paid by the Short Duration
 Tax-Free and Municipal Income Funds may be an item of tax preference for
 purposes of determining your federal alternative minimum tax liability.
 Exempt-interest dividends will also be considered along with other adjusted
 gross income in determining whether any Social Security or railroad retire-
 ment payments received by you are subject to federal income taxes.
 
 If you receive an exempt-interest dividend on shares that are held by you
 for six months or less, any loss on the sale or exchange of the shares will
 be disallowed to the extent of such dividend amount.
 
 There are certain tax requirements that all Funds must follow in order to
 avoid federal taxation. In their efforts to adhere to these requirements,
 the Funds may have to limit their investment activity in some types of
 instruments.
 
 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Fund shares may generate a tax liability (unless
 your investment is in an IRA or other tax-advantaged account). Depending
 upon the purchase or sale price of the shares you sell or exchange, you may
 have a gain or a loss on the transaction.
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Fund, based on the
 difference between your tax basis in the shares and the amount you receive
 for them. (To aid in computing your tax basis, you generally should retain
 your account statements for the periods that you hold shares.) Any loss rec-
 ognized on shares held for six months or less will be treated as a long-term
 capital loss to the extent of any capital gain dividends that were received
 with respect to the shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from any Fund (including the Short Dura-
 tion Tax-Free and Municipal Income Funds) or on the value of the shares held
 by you. More tax information is provided in the Additional Statement. You
 should also consult your own tax adviser for information regarding all tax
 consequences applicable to your investments in the Funds.

<PAGE>
 
Appendix A
Additional Information on Portfolio Risks, Securities and Techniques
 A. General Portfolio Risks
 
 
 The Funds will be subject to the risks associated with fixed-income securi-
 ties. These risks include interest rate risk, credit risk and call/extension
 risk. In general, interest rate risk involves the risk that when interest
 rates decline, the market value of fixed-income securities tends to
 increase. Conversely, when interest rates increase, the market value of
 fixed-income securities tends to decline. Credit risk involves the risk that
 the issuer could default on its obligations, and a Fund will not recover its
 investment. Call risk and extension risk are normally present in adjustable
 rate mortgage loans ("ARMs"), Mortgage-Backed Securities and asset-backed
 securities. For example, homeowners have the option to prepay their mort-
 gages. Therefore, the duration of a security backed by home mortgages can
 either shorten (call risk) or lengthen (extension risk). In general, if
 interest rates on new mortgage loans fall sufficiently below the interest
 rates on existing outstanding mortgage loans, the rate of prepayment would
 be expected to increase. Conversely, if mortgage loan interest rates rise
 above the interest rates on existing outstanding mortgage loans, the rate of
 prepayment would be expected to decrease. In either case, a change in the
 prepayment rate can result in losses to investors.
 
 The Investment Adviser will not consider the portfolio turnover rate a lim-
 iting factor in making investment decisions for a Fund. A high rate of port-
 folio turnover (100% or more) involves correspondingly greater expenses
 which must be borne by a Fund and its shareholders. The portfolio turnover
 rate is calculated by dividing the lesser of the dollar amount of sales or
 purchases of portfolio securities by the average monthly value of a Fund's
 portfolio securities, excluding securities having a maturity at the date of
 purchase of one year or less. See "Financial Highlights" in Appendix B for a
 statement of the Funds' historical portfolio turnover rates.
 
 The following sections provide further information on certain types of secu-
 rities and investment techniques that may be used by the Funds, including
 their associated risks. Additional information is provided in the Additional
 Statement, which is available upon request. Among other things, the Addi-
 tional Statement describes certain fundamental investment restrictions that
 cannot be changed without shareholder approval. You should note, however,
 that all policies not specifically designated as fundamental are non-funda-
 mental and may
 
                                                                              55
<PAGE>
 
 
 be changed without shareholder approval. If there is a change in a Fund's
 investment objective, you should consider whether that Fund remains an
 appropriate investment in light of your then current financial positions and
 needs.
 
 B. Other Portfolio Risks
 
 
 Credit Risks. Debt securities purchased by the Funds may include securities
 (including zero coupon bonds) issued by the U.S. government (and its agen-
 cies, instrumentalities and sponsored enterprises), foreign governments,
 domestic and foreign corporations, banks and other issuers. Some of these
 fixed-income securities are described in the next section below. Further
 information is provided in the Additional Statement.
 
 Debt securities rated BBB or higher by Standard & Poor's or Baa or higher by
 Moody's are considered "investment grade." Securities rated BBB or Baa are
 considered medium-grade obligations with speculative characteristics, and
 adverse economic conditions or changing circumstances may weaken their
 issuers' capacity to pay interest and repay principal. A security will be
 deemed to have met a rating requirement if it receives the minimum required
 rating from at least one such rating organization even though it has been
 rated below the minimum rating by one or more other rating organizations, or
 if unrated by such rating organizations, is determined by the Investment
 Adviser to be of comparable credit quality.
 
 Certain Funds may invest in fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) which are commonly referred to as "junk
 bonds." Junk bonds are considered predominantly speculative and may be ques-
 tionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in a Fund's portfolio is downgraded by a rat-
 ing organization, the market price and liquidity of such security may be
 adversely affected.
 
 Risks of Derivative Investments. A Fund's transactions, if any, in options,
 futures, options on futures, swaps, interest rate caps, floors and collars,
 structured securities, inverse floating-rate securities, stripped mortgage-
 backed securities and currency transactions involve additional risk of loss.
 Loss can result from a lack of correlation between changes in the value of
 derivative instruments and the portfolio assets (if any) being hedged, the
 potential illiquidity of the markets for derivative instruments, or the
 risks arising from margin requirements and related lever-
 
56

                                                                      APPENDIX A
 
 age factors associated with such transactions. The use of these management
 techniques also involves the risk of loss if the Investment Adviser is
 incorrect in its expectation of fluctuations in securities prices, interest
 rates or currency prices. Each Fund may also invest in derivative invest-
 ments for non-hedging purposes (that is, to seek to increase total return),
 which is considered a speculative practice and presents even greater risk of
 loss.
 
 Derivative Mortgage-Backed Securities (such as principal-only ("POs"),
 interest-only ("IOs") or inverse floating rate securities) are particularly
 exposed to call and extension risks. Small changes in mortgage prepayments
 can significantly impact the cash flow and the market value of these securi-
 ties. In general, the risk of faster than anticipated prepayments adversely
 affects IOs, super floaters and premium priced Mortgage-Backed Securities.
 The risk of slower than anticipated prepayments generally adversely affects
 POs, floating-rate securities subject to interest rate caps, support
 tranches and discount priced Mortgage-Backed Securities. In addition, par-
 ticular derivative securities may be leveraged such that their exposure
 (i.e., price sensitivity) to interest rate and/or prepayment risk is
 magnified.
 
 Some floating-rate derivative debt securities can present more complex types
 of derivative and interest rate risks. For example, range floaters are sub-
 ject to the risk that the coupon will be reduced below market rates if a
 designated interest rate floats outside of a specified interest rate band or
 collar. Dual index or yield curve floaters are subject to lower prices in
 the event of an unfavorable change in the spread between two designated
 interest rates.
 
 Risks of Foreign Investments. Foreign investments involve special risks that
 are not typically associated with U.S. dollar denominated or quoted securi-
 ties of U.S. issuers. Foreign investments may be affected by changes in cur-
 rency rates, changes in foreign or U.S. laws or restrictions applicable to
 such investments and changes in exchange control regulations (e.g., currency
 blockage). A decline in the exchange rate of the currency (i.e., weakening
 of the currency against the U.S. dollar) in which a portfolio security is
 quoted or denominated relative to the U.S. dollar would reduce the value of
 the portfolio security. In addition, if the currency in which a Fund
 receives dividends, interest or other payments declines in value against the
 U.S. dollar before such income is distributed as dividends to shareholders
 or converted to U.S. dollars, the Fund may have to sell portfolio securities
 to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts
 
                                                                              57

 after January 1, 1999 that refer to existing currencies rather than the
 euro; the establishment and maintenance of exchange rates for currencies
 being converted into the euro; the fluctuation of the euro relative to non-
 euro currencies during the transition period from January 1, 1999 to Decem-
 ber 31, 2001 and beyond; whether the interest rate, tax and labor regimes of
 European countries participating in the euro will converge over time; and
 whether the conversion of the currencies of other countries that now are or
 may in the future become members of the European Union ("EU") may have an
 impact on the euro. These or other factors, including political and economic
 risks, could cause market disruptions, and could adversely affect the value
 of securities held by the Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than a U.S. issuer. In addition, there is generally less government
 regulation of foreign markets, companies and securities dealers than in the
 United States. Foreign securities markets may have substantially less volume
 than U.S. securities markets and securities of many foreign issuers are less
 liquid and more volatile than securities of comparable domestic issuers.
 Furthermore, with respect to certain foreign countries, there is a possibil-
 ity of nationalization, expropriation or confiscatory taxation, imposition
 of withholding or other taxes on dividend or interest payments (or, in some
 cases, capital gains), limitations on the removal of funds or other assets
 of the Funds, and political or social instability or diplomatic developments
 which could affect investments in those countries.
 
 Concentration of a Fund's assets in one or a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations by certain Funds involves risks not
 present in debt obligations of corporate issuers. The issuer of the debt or
 the governmental authorities that control the repayment of the debt may be
 unable or unwilling to repay principal or interest when due in accordance
 with the terms of such
 
58
<PAGE>
 
                                                                      APPENDIX A
 
 debt, and a Fund may have limited recourse to compel payment in the event of
 a default. Periods of economic uncertainty may result in volatility of mar-
 ket prices of sovereign debt, and in turn a Fund's NAV, to a greater extent
 than the volatility inherent in debt obligations of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Risks of Emerging Countries. Certain Funds may invest in securities of
 issuers located in emerging countries. The risks of foreign investment are
 heightened when the issuer is located in an emerging country. Emerging coun-
 tries are generally located in the Asia-Pacific region, Eastern Europe,
 Latin and South America and Africa. A Fund's purchase and sale of portfolio
 securities in certain emerging countries may be constrained by limitations
 as to daily changes in the prices of listed securities, periodic trading or
 settlement volume and/or limitations on aggregate holdings of foreign
 investors. Such limitations may be computed based on the aggregate trading
 volume by or holdings of a Fund, the Investment Adviser, its affiliates and
 their respective clients and other service providers. A Fund may not be able
 to sell securities in circumstances where price, trading or settlement vol-
 ume limitations have been reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, such as Taiwan, it is
 anticipated that a Fund may invest in such countries only through other
 investment funds in such countries.
 
                                                                              59

 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and ethnic, religious and racial disaffec-
 tion, among other factors, have also led to social unrest, violence and/or
 labor unrest in some emerging countries. Unanticipated political or social
 developments may result in sudden and significant investment losses. Invest-
 ing in emerging countries involves greater risk of loss due to expropria-
 tion, nationalization, confiscation of assets and property or the imposition
 of restrictions on foreign investments and on repatriation of capital
 invested.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of those emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 A Fund's investment in emerging countries may also be subject to withholding
 or other taxes, which may be significant and may reduce the return from an
 investment in such country to the Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve a Fund's
 delivery of securities before receipt of payment for their sale. In addi-
 tion, significant delays are common in certain markets in registering the
 transfer of securities. Settlement or registration problems may make it more
 difficult for a Fund to value its portfolio securities and could cause the
 Fund to miss attractive investment opportunities, to have a portion of its
 assets uninvested or to incur losses due to the failure of a counterparty to
 pay for securities the Fund has delivered or the Fund's inability to com-
 plete its contractual obligations. The creditworthiness of the local securi-
 ties firms used by the Funds in emerging countries may not be as sound as
 the creditworthiness of firms used in more developed countries. As a result,
 the Fund may be subject to a greater risk of loss if a securities firm
 defaults in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make a Fund's investments in such countries less liquid and more
 volatile than invest-

                                                                      APPENDIX A
 
 ments in countries with more developed securities markets (such as the
 United States, Japan and most Western European countries). A Fund's invest-
 ments in emerging countries are subject to the risk that the liquidity of
 particular investment, or investments generally, in such countries will
 shrink or disappear suddenly and without warning as a result of adverse eco-
 nomic, market or political conditions or adverse investor perceptions,
 whether or not accurate. Because of the lack of sufficient market liquidity,
 a Fund may incur losses because it will be required to effect sales at a
 disadvantageous time and then only at a substantial drop in price. Invest-
 ments in emerging countries may be more difficult to price precisely because
 of these characteristics and lower trading volumes.
 
 A Fund's use of foreign currency management techniques in emerging countries
 may be limited. Due to the limited market for these instruments in emerging
 countries, the Investment Adviser does not currently anticipate that a sig-
 nificant portion of the Funds' currency exposure in emerging countries, if
 any, will be covered by such instruments.
 
 Risks of Illiquid Securities. Each Fund may invest up to 15% of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
 
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped Mortgage-Backed Securities
 .Repurchase agreements and time deposits with a notice or demand period of
  more than seven days
 .Certain over-the-counter options
 .Certain restricted securities, unless it is determined, based upon a review
  of the trading markets for a specific restricted security, that such
  restricted security is eligible for resale pursuant to Rule 144A under the
  Securities Act of 1933 ("144A Securities") and, therefore, is liquid
 
 Investing in 144A Securities may decrease the liquidity of a Fund's portfo-
 lio to the extent that qualified institutional buyers become for a time
 uninterested in purchasing these restricted securities. The purchase price
 and subsequent valuation of restricted and illiquid securities normally
 reflect a discount, which may be significant, from the market price of com-
 parable securities for which a liquid market exists.
 
 Temporary Investment Risks. Each Fund may, for temporary defensive purposes,
 invest a certain percentage of its total assets in:
 
 .U.S. Government Securities
 .Repurchase agreements collateralized by U.S. Government Securities
 
                                                                              61
<PAGE>
 
 
 Certain Funds may invest more than 20% of their respective net assets in
 taxable investments and in investment grade securities for temporary defen-
 sive purposes.
 
 C. Portfolio Securities and Techniques
 
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the Funds, including their associ-
 ated risks. Further information is provided in the Additional Statement,
 which is available upon request.
 
 U.S. Government Securities and Related Custodial Receipts. U.S. Government
 Securities include U.S. Treasury obligations and obligations issued or guar-
 anteed by U.S. government agencies, instrumentalities or sponsored enter-
 prises. U.S. Government Securities may be supported by (a) the full faith
 and credit of the U.S. Treasury (such as the Government National Mortgage
 Association ("Ginnie Mae")); (b) the right of the issuer to borrow from the
 U.S. Treasury (such as securities of the Student Loan Marketing Associa-
 tion); (c) the discretionary authority of the U.S. government to purchase
 certain obligations of the issuer (such as the Federal National Mortgage
 Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation
 ("Freddie Mac")); or (d) only the credit of the issuer. U.S. Government
 Securities also include Treasury receipts, zero coupon bonds and other
 stripped U.S. Government Securities, where the interest and principal compo-
 nents of stripped U.S. Government Securities are traded independently.
 
 Interests in U.S. Government Securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S. govern-
 ment.
 
 Mortgage-Backed Securities. Mortgage-Backed Securities represent direct or
 indirect participations in, or are collateralized by and payable from, mort-
 gage loans secured by real property. Mortgage-Backed Securities can be
 backed by either fixed rate mortgage loans or adjustable rate mortgage
 loans, and may be issued by either a governmental or non-governmental enti-
 ty. Privately issued Mortgage-Backed Securities are normally structured with
 one or more types of "credit enhancement." However, these Mortgage-Backed
 Securities typically do not have the same credit standing as U.S. government
 guaranteed Mortgage-Backed Securities.

                                                                      APPENDIX A
 
 Mortgage-Backed Securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs") and Real Estate Mortgage
 Investment Conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an investor with a specified interest in the cash flow from a
 pool of underlying mortgages or of other Mortgage-Backed Securities. CMOs
 are issued in multiple classes. In most cases, payments of principal are
 applied to the CMO classes in the order of their respective stated maturi-
 ties, so that no principal payments will be made on a CMO class until all
 other classes having an earlier stated maturity date are paid in full. A
 REMIC is a CMO that qualifies for special tax treatment under the Code and
 invests in certain mortgages principally secured by interests in real prop-
 erty and other permitted investments.
 
 Mortgaged-Backed Securities also include stripped Mortgage-Backed Securities
 ("SMBS"), which are derivative multiple class Mortgage-Backed Securities.
 SMBS are usually structured with two different classes: one that receives
 100% of the interest payments and the other that receives 100% of the prin-
 cipal payments from a pool of mortgage loans. The market value of SMBS con-
 sisting entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage loans are generally higher than pre-
 vailing market yields on other Mortgage-Backed Securities because their cash
 flow patterns are more volatile and there is a greater risk that the initial
 investment will not be fully recouped.
 
 Asset-Backed Securities. Asset-backed securities are securities whose prin-
 cipal and interest payments are collateralized by pools of assets such as
 auto loans, credit card receivables, leases, installment contracts and per-
 sonal property. Asset-backed securities are often subject to more rapid
 repayment than their stated maturity date would indicate as a result of the
 pass-through of prepayments of principal on the underlying loans. During
 periods of declining interest rates, prepayment of loans underlying asset-
 backed securities can be expected to accelerate. Accordingly, a Fund's abil-
 ity to maintain positions in such securities will be affected by reductions
 in the principal amount of such securities resulting from prepayments, and
 its ability to reinvest the returns of principal at comparable yields is
 subject to generally prevailing interest rates at that time. Asset-backed
 securities present credit risks that are not presented by Mortgage-Backed
 Securities. This is because asset-backed securities generally do not have
 the benefit of a security interest in collateral that is comparable to mort-
 gage assets. There is the possibility that, in some cases, recoveries on
 repossessed collateral may not be available to support payments on these
 securities. In the event of a default, a Fund may suffer a loss if it cannot
 sell collateral quickly and receive the amount it is owed.
 
 
                                                                              63
<PAGE>
 
 
 Municipal Securities. Municipal Securities include bonds, notes, commercial
 paper and other instruments (including participation interests in such secu-
 rities) issued by or on behalf of the states, territories and possessions of
 the United States (including the District of Columbia) and their political
 subdivisions, agencies or instrumentalities, the interest on which, in the
 opinion of bond counsel for the issuers or counsel selected by the Invest-
 ment Adviser, is exempt from regular federal income tax (i.e., excluded from
 gross income for federal income tax purposes but not necessarily exempt from
 federal alternative minimum tax or from state or local taxes). Because of
 their tax-exempt status, the yields and market values of Municipal Securi-
 ties may be more adversely impacted by changes in tax rates and policies
 than taxable fixed-income securities.
 
 Municipal Securities are often issued to obtain funds for various public
 purposes, including the construction of a wide range of public facilities
 such as bridges, highways, housing, hospitals, mass transportation, schools,
 streets and water and sewer works. Municipal Securities include private
 activity bonds, municipal leases, certificates of participation, pre-
 refunded municipal securities and auction rate securities.
 
 The obligations of the issuer to pay the principal of and interest on a
 Municipal Security are subject to the provisions of bankruptcy, insolvency
 and other laws affecting the rights and remedies of creditors, such as the
 Federal Bankruptcy Act, and laws, if any, that may be enacted by Congress or
 state legislatures extending the time for payment of principal or interest
 or imposing other constraints upon the enforcement of such obligations.
 There is also the possibility that, as a result of litigation or other con-
 ditions, the power or ability of the issuer to pay when due the principal of
 or interest on a Municipal Security may be materially affected. Municipal
 lease obligations and certificates of participation are subject to the added
 risk that the governmental lessee will fail to appropriate funds to enable
 it to meet its payment obligations under the lease.
 
 Municipal Securities may be in the form of a tender option bond, which is a
 Municipal Security (generally held pursuant to a custodial arrangement) hav-
 ing a relatively long maturity and bearing interest at a fixed rate substan-
 tially higher than prevailing short-term, tax-exempt rates. The bond is typ-
 ically issued with the agreement of a bank, broker-dealer or other financial
 institution, which grants the security holders the option, at periodic
 intervals, to tender their securities to the institution and receive the
 face value thereof. After payment of a fee to the financial institution that
 provides this option, the security holder effectively holds a demand obliga-
 tion that bears interest at the prevailing short-term, tax-exempt rate. The
 tender option will be taken into account in determining the maturity of the
 tender option bonds and a Fund's average portfolio maturity. There is risk
 that a

                                                                      APPENDIX A
 
 Fund will not be considered the owner of a tender option bond for federal
 income tax purposes, and thus will not be entitled to treat such interest as
 exempt from federal income tax. Certain tender option bonds may be illiquid.
 
 Corporate Debt Obligations; Trust Preferred Securities; Convertible Securi-
 ties. Corporate debt obligations include bonds, notes, debentures and other
 obligations of corporations to pay interest and repay principal, and include
 securities issued by banks and other financial institutions. A trust pre-
 ferred or capital security is a long dated bond (for example, 30 years) with
 preferred features. The preferred features are that payment of interest can
 be deferred for a specified period without initiating a default event. The
 securities are generally senior in claim to standard preferred stock but
 junior to other bondholders.
 
 Convertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than non-convertible securities of similar qual-
 ity. Convertible securities in which a Fund invests are subject to the same
 rating criteria as its other investments in fixed-income securities. Con-
 vertible securities have both equity and fixed-income risk characteristics.
 Like all fixed-income securities, the value of convertible securities is
 susceptible to the risk of market losses attributable to changes in interest
 rates. Generally, the market value of convertible securities tends to
 decline as interest rates increase and, conversely, to increase as interest
 rates decline. However, when the market price of the common stock underlying
 a convertible security exceeds the conversion price of the convertible secu-
 rity, the convertible security tends to reflect the market price of the
 underlying common stock. As the market price of the underlying common stock
 declines, the convertible security, like a fixed-income security, tends to
 trade increasingly on a yield basis, and thus may not decline in price to
 the same extent as the underlying common stock.
 
 Foreign Currency Transactions. A Fund may, to the extent consistent with its
 investment policies, purchase or sell foreign currencies on a cash basis or
 through forward contracts. A forward contract involves an obligation to pur-
 chase or sell a specific currency at a future date at a price set at the
 time of the contract. A Fund may engage in foreign currency transactions for
 hedging purposes and to seek to protect against anticipated changes in
 future foreign currency exchange rates. In addition, a Fund also may enter
 into such transactions to seek to increase total return, which is considered
 a speculative practice.
 
 Some Funds may also engage in cross-hedging by using forward contracts in a
 currency different from that in which the hedged security is denominated or
 quoted if the Investment Adviser determines that there is a pattern of cor-
 relation between the two currencies. A Fund may hold foreign currency
 received in con-
 
                                                                              65
<PAGE>
 
 
 nection with investments in foreign securities when, in the judgment of the
 Investment Adviser, it would be beneficial to convert such currency into
 U.S. dollars at a later date.
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, a Fund's NAV to fluctuate (when the
 Fund's NAV fluctuates, the value of your shares may go up or down). Currency
 exchange rates also can be affected unpredictably by the intervention of
 U.S. or foreign governments or central banks, or the failure to intervene,
 or by currency controls or political developments in the United States or
 abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are not guaranteed by an exchange or clear-
 inghouse, a default on a contract would deprive a Fund of unrealized prof-
 its, transaction costs or the benefits of a currency hedge or could force
 the Fund to cover its purchase or sale commitments, if any, at the current
 market price.
 
 Structured Securities and Inverse Floaters. Structured securities are secu-
 rities whose value is determined by reference to changes in the value of
 specific currencies, interest rates, commodities, indices or other financial
 indicators (the "Reference") or the relative change in two or more Refer-
 ences. The interest rate or the principal amount payable upon maturity or
 redemption may be increased or decreased depending upon changes in the
 applicable Reference. Structured securities may be positively or negatively
 indexed, so that appreciation of the Reference may produce an increase or
 decrease in the interest rate or value of the security at maturity. In addi-
 tion, changes in the interest rates or the value of the security at maturity
 may be a multiple of changes in the value of the Reference. Consequently,
 structured securities may present a greater degree of market risk than other
 types of fixed-income securities, and may be more volatile, less liquid and
 more difficult to price accurately than less complex securities.
 
 Structured securities include, but are not limited to, inverse floating rate
 debt securities ("inverse floaters"). The interest rate on inverse floaters
 resets in the opposite direction from the market rate of interest to which
 the inverse floater is indexed. An inverse floater may be considered to be
 leveraged to the extent that its interest rate varies by a magnitude that
 exceeds the magnitude of the change in the index rate of interest. The
 higher the degree of leverage of an inverse floater, the greater the vola-
 tility of its market value.

 Zero Coupon, Deferred Interest, Pay-In-Kind and Capital Appreciation Bonds.
 Zero coupon, deferred interest, pay-in-kind and capital appreciation bonds
 are issued at a discount from their face value because interest payments are
 typically postponed until maturity. Pay-in-kind securities are securities
 that have interest payable by the delivery of additional securities. The
 market prices of these securities generally are more volatile than the mar-
 ket prices of interest-bearing securities and are likely to respond to a
 greater degree to changes in interest rates than interest-bearing securities
 having similar maturities and credit quality.
 
 Mortgage Dollar Rolls. A mortgage dollar roll involves the sale by a Fund of
 securities for delivery in the current month. The Fund simultaneously con-
 tracts with the same counterparty to repurchase substantially similar (same
 type, coupon and maturity) but not identical securities on a specified
 future date. During the roll period, the Fund loses the right to receive
 principal and interest paid on the securities sold. However, the Fund bene-
 fits to the extent of any difference between (a) the price received for the
 securities sold and (b) the lower forward price for the future purchase
 and/or fee income plus the interest earned on the cash proceeds of the secu-
 rities sold. Unless the benefits of a mortgage dollar roll exceed the
 income, capital appreciation and gain or loss due to mortgage prepayments
 that would have been realized on the securities sold as part of the roll,
 the use of this technique will diminish the Fund's performance.
 
 Successful use of mortgage dollar rolls depends upon the Investment Advis-
 er's ability to predict correctly interest rates and mortgage prepayments.
 If the Investment Adviser is incorrect in its prediction, a Fund may experi-
 ence a loss. For financial reporting and tax purposes, the Funds treat mort-
 gage dollar rolls as two separate transactions: one involving the purchase
 of a security and a separate transaction involving a sale. The Funds do not
 currently intend to enter into mortgage dollar rolls that are accounted for
 as a financing and do not treat them as borrowings.
 
 Options on Securities, Securities Indices and Foreign Currencies. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Fund may write
 (sell) covered call and put options and purchase put and call options on any
 securities in which it may invest or on any securities index comprised of
 securities in which it may invest. A Fund that invests in foreign securities
 may also purchase and sell (write) put and call options on foreign curren-
 cies.
 
 
                                                                              67
<PAGE>
 
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of the Investment Adviser to manage future price fluctu-
 ations and the degree of correlation between the options and securities (or
 currency) markets. If the Investment Adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in a Fund's investment portfolio, the Fund may incur losses that
 it would not otherwise incur. The use of options can also increase a Fund's
 transaction costs. Options written or purchased by the Funds may be traded
 on either U.S. or foreign exchanges or over-the-counter. Foreign and over-
 the-counter options will present greater possibility of loss because of
 their greater liquidity and credit risks.
 
 Yield Curve Options. Each Fund may enter into options on the yield "spread"
 or differential between two securities. Such transactions are referred to as
 "yield curve" options. In contrast to other types of options, a yield curve
 option is based on the difference between the yields of designated securi-
 ties, rather than the prices of the individual securities, and is settled
 through cash payments. Accordingly, a yield curve option is profitable to
 the holder if this differential widens (in the case of a call) or narrows
 (in the case of a put), regardless of whether the yields of the underlying
 securities increase or decrease.
 
 The trading of yield curve options is subject to all of the risks associated
 with the trading of other types of options. In addition, such options pres-
 ent a risk of loss even if the yield of one of the underlying securities
 remains constant, or if the spread moves in a direction or to an extent
 which was not anticipated.
 
 Futures Contracts and Options on Futures Contracts. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 Government Securities), foreign currencies, securities indices and other
 financial instruments and indices. The Funds may engage in futures transac-
 tions on both U.S. and foreign exchanges.
 
 Each Fund may purchase and sell futures contracts, and purchase and write
 call and put options on futures contracts, in order to seek to increase
 total return or to hedge against changes in interest rates, securities
 prices or, to the extent a Fund invests in foreign securities, currency
 exchange rates, or to otherwise manage their

 term structures, sector selection and durations in accordance with their
 investment objectives and policies. Each Fund may also enter into closing
 purchase and sale transactions with respect to such contracts and options. A
 Fund will engage in futures and related options transactions for bona fide
 hedging purposes as defined in regulations of the Commodity Futures Trading
 Commission or to seek to increase total return to the extent permitted by
 such regulations. A Fund may not purchase or sell futures contracts or pur-
 chase or sell related options to seek to increase total return, except for
 closing purchase or sale transactions, if immediately thereafter the sum of
 the amount of initial margin deposits and premiums paid on the Fund's out-
 standing positions in futures and related options entered into for the pur-
 pose of seeking to increase total return would exceed 5% of the market value
 of the Fund's net assets.
 
 Futures contracts and related options present the following risks:
  .While a Fund may benefit from the use of futures and options on futures,
   unanticipated changes in interest rates, securities prices or currency
   exchange rates may result in poorer overall performance than if the Fund
   had not entered into any futures contracts or options transactions.
  .Because perfect correlation between a futures position and portfolio
   position that is intended to be protected is impossible to achieve, the
   desired protection may not be obtained and a Fund may be exposed to
   additional risk of loss.
  .The loss incurred by a Fund in entering into futures contracts and in
   writing call options on futures is potentially unlimited and may exceed
   the amount of the premium received.
  .Futures markets are highly volatile and the use of futures may increase
   the volatility of a Fund's NAV.
  .As a result of the low margin deposits normally required in futures
   trading, a relatively small price movement in a futures contract may
   result in substantial losses to a Fund.
  .Futures contracts and options on futures may be illiquid, and exchanges
   may limit fluctuations in futures contract prices during a single day.
  .Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to the Fund at the time of entering into the
 transaction. A forward commitment involves entering into a contract to pur-
 chase or sell securities for a fixed price at a future date beyond the cus-
 tomary settlement period.
 
 
                                                                              69
<PAGE>
 
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although a Fund will generally
 purchase securities on a when-issued or forward commitment basis with the
 intention of acquiring securities for its portfolio, a Fund may dispose of
 when-issued securities or forward commitments prior to settlement if the
 Investment Adviser deems it appropriate.
 
 Lending of Portfolio Securities. Securities lending involves the lending of
 securities owned by a Fund to financial institutions such as certain broker-
 dealers. The borrowers are required to secure their loans continuously with
 cash, cash equivalents, U.S. Government Securities or letters of credit in
 an amount at least equal to the market value of the securities loaned. Cash
 collateral may be invested in cash equivalents. If the Investment Adviser
 determines to make securities loans, the value of the securities loaned may
 not exceed 33 1/3% of the value of the total assets of a Fund (including the
 loan collateral).
 
 A Fund may lend its securities to increase its income. A Fund may, however,
 experience delay in the recovery of its securities if the institution with
 which it has engaged in a portfolio loan transaction breaches its agreement
 with the Fund.
 
 Repurchase Agreements. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Fund may enter into repurchase agreements
 with dealers in U.S. Government Securities and member banks of the Federal
 Reserve System which furnish collateral at least equal in value or market
 price to the amount of their repurchase obligation. Some Funds may also
 enter into repurchase agreements involving certain foreign government secu-
 rities.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund are less than the repurchase price and the
 Fund's cost associated with delay and enforcement of the repurchase agree-
 ment. In addition, in the event of bankruptcy of the seller, a Fund could
 suffer additional losses if a court determines that the Fund's interest in
 the collateral is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to a Fund's
 shareholders. In addition, certain Funds, together with other registered
 investment companies having advisory agreements with the Investment Adviser
 or any of its affiliates, may transfer uninvested cash balances into a sin-
 gle joint account, the daily aggregate balance of which will be invested in
 one or more repurchase agreements.

 Borrowings and Reverse Repurchase Agreements. The Funds can borrow money
 from banks and enter into reverse repurchase agreements with banks and other
 financial institutions in amounts not exceeding one-third of its total
 assets. Reverse repurchase agreements involve the sale of securities held by
 a Fund subject to the Fund's agreement to repurchase them at a mutually
 agreed upon date and price (including interest). These transactions may be
 entered into as a temporary measure for emergency purposes or to meet
 redemption requests. Reverse repurchase agreements may also be entered into
 when the Investment Adviser expects that the interest income to be earned
 from the investment of the transaction proceeds will be greater than the
 related interest expense. Borrowings and reverse repurchase agreements
 involve leveraging. If the securities held by a Fund decline in value while
 these transactions are outstanding, the NAV of the Fund's outstanding shares
 will decline in value by proportionately more than the decline in value of
 the securities. In addition, reverse repurchase agreements involve the risk
 that the interest income earned by a Fund (from the investment of the pro-
 ceeds) will be less than the interest expense of the transaction, that the
 market value of the securities sold by a Fund will decline below the price
 the Fund is obligated to pay to repurchase the securities, and that the
 securities may not be returned to the Fund.
 
 Interest Rate Swaps, Mortgage Swaps, Credit Swaps, Currency Swaps and Inter-
 est Rate Caps, Floors and Collars. Interest rate swaps involve the exchange
 by a Fund with another party of their respective commitments to pay or
 receive interest, such as an exchange of fixed-rate payments for floating
 rate payments. Mortgage swaps are similar to interest rate swaps in that
 they represent commitments to pay and receive interest. The notional princi-
 pal amount, however, is tied to a reference pool or pools of mortgages.
 Credit swaps involve the receipt of floating or fixed rate payments in
 exchange for assuming potential credit losses of an underlying security.
 Credit swaps give one party to a transaction the right to dispose of or
 acquire an asset (or group of assets), or the right to receive or make a
 payment from the other party, upon the occurrence of specified credit
 events. Currency swaps involve the exchange of the parties' respective
 rights to make or receive payments in specified currencies. The purchase of
 an interest rate cap entitles the purchaser, to the extent that a specified
 index exceeds a predetermined interest rate, to receive payment of interest
 on a notional principal amount from the party selling such interest rate
 cap. The purchase of an interest rate floor entitles the purchaser, to the
 extent that a specified index falls below a predetermined interest rate, to
 receive payments of interest on a notional principal amount from the party
 selling the interest rate floor. An interest rate collar is the combination
 of a cap and a floor that preserves a certain return within a predetermined
 range of interest rates.
 
 
                                                                              71
<PAGE>
 
 
 Each Fund may enter into swap transactions for hedging purposes or to seek
 to increase total return. The use of interest rate, mortgage, credit and
 currency swaps, as well as interest rate caps, floors and collars, is a
 highly specialized activity which involves investment techniques and risks
 different from those associated with ordinary portfolio securities transac-
 tions. If the Investment Adviser is incorrect in its forecasts of market
 value, interest rates and currency exchange rates, the investment perfor-
 mance of a Fund would be less favorable than it would have been if these
 investment techniques were not used.
 
 Other Investment Companies. A Fund may invest in securities of other invest-
 ment companies subject to the limitations prescribed by the Act. These limi-
 tations include a prohibition on any Fund acquiring more than 3% of the vot-
 ing shares of any other investment company, and a prohibition on investing
 more than 5% of a Fund's total assets in securities of any one investment
 company or more than 10% of its total assets in securities of all investment
 companies. A Fund will indirectly bear its proportionate share of any man-
 agement fees and other expenses paid by such other investment companies.
 Such other investment companies will have investment objectives, policies
 and restrictions substantially similar to those of the acquiring Fund and
 will be subject to substantially the same risks.
 
 Non-Investment Grade Fixed-Income Securities. Non-investment grade fixed-
 income securities and unrated securities of comparable credit quality (com-
 monly known as "junk bonds") are considered predominantly speculative by
 traditional investment standards. In some cases, these obligations may be
 highly speculative and have poor prospects for reaching investment grade
 standing. Non-investment grade fixed-income securities are subject to the
 increased risk of an issuer's inability to meet principal and interest obli-
 gations. These securities, also referred to as high yield securities, may be
 subject to greater price volatility due to such factors as specific corpo-
 rate developments, interest rate sensitivity, negative perceptions of the
 junk bond markets generally and less secondary market liquidity.
 
 Non-investment grade fixed-income securities are often issued in connection
 with a corporate reorganization or restructuring or as part of a merger,
 acquisition, takeover or similar event. They are also issued by less estab-
 lished companies seeking to expand. Such issuers are often highly leveraged
 and generally less able than more established or less leveraged entities to
 make scheduled payments of principal and interest in the event of adverse
 developments or business conditions.
 
 The market value of non-investment grade fixed-income securities tends to
 reflect individual corporate developments to a greater extent than that of
 higher rated securities which react primarily to fluctuations in the general
 level of interest

                                                                      APPENDIX A
 
 rates. As a result, a Fund's ability to achieve its investment objectives
 may depend to a greater extent on the Investment Adviser's judgment concern-
 ing the creditworthiness of issuers than funds which invest in higher-rated
 securities. Issuers of non-investment grade fixed-income securities may not
 be able to make use of more traditional methods of financing and their abil-
 ity to service debt obligations may be affected more adversely than issuers
 of higher-rated securities by economic downturns, specific corporate devel-
 opments or the issuer's inability to meet specific projected business fore-
 casts. Negative publicity about the junk bond market and investor percep-
 tions regarding lower rated securities, whether or not based on fundamental
 analysis, may depress the prices for such securities.
 
 A holder's risk of loss from default is significantly greater for non-
 investment grade fixed-income securities than is the case for holders of
 other debt securities because such non-investment grade securities are gen-
 erally unsecured and are often subordinated to the rights of other creditors
 of the issuers of such
 securities. Investment by a Fund in defaulted securities poses additional
 risk of loss should nonpayment of principal and interest continue in respect
 of such securities. Even if such securities are held to maturity, recovery
 by a Fund of its initial investment and any anticipated income or apprecia-
 tion is uncertain.
 
 The secondary market for non-investment grade fixed-income securities is
 concentrated in relatively few market makers and is dominated by institu-
 tional investors, including mutual funds, insurance companies and other
 financial institutions. Accordingly, the secondary market for such securi-
 ties is not as liquid as, and is more volatile than, the secondary market
 for higher-rated securities. In addition, market trading volume for high
 yield fixed-income securities is generally lower and the secondary market
 for such securities could shrink or disappear suddenly and without warning
 as a result of adverse market or economic conditions, independent of any
 specific adverse changes in the condition of a particular issuer. Because of
 the lack of sufficient market liquidity, a Fund may incur losses because it
 will be required to effect sales at a disadvantageous time and then may at a
 substantial drop in price. These factors may have an adverse effect on the
 market price and a Fund's ability to dispose of particular portfolio invest-
 ments. A less liquid secondary market also may make it more difficult for a
 Fund to obtain precise valuations of the high yield securities in its port-
 folio.
 
 Credit ratings issued by credit rating agencies are designed to evaluate the
 safety of principal and interest payments of rated securities. They do not,
 however, evaluate the market value risk of non-investment grade securities
 and, therefore, may not fully reflect the true risks of an investment. In
 addition, credit rating agencies may or may not make timely changes in a
 rating to reflect changes in the economy or in the conditions of the issuer
 that affect the market value of the security.
 
                                                                              73
<PAGE>
 
 
 Consequently, credit ratings are used only as a preliminary indicator of
 investment quality. Investments in non-investment grade and comparable
 unrated obligations will be more dependent on the Investment Adviser's
 credit analysis than would be the case with investments in investment-grade
 debt obligations.
 
 Loan Participations. A loan participation is an interest in a loan to a U.S.
 or foreign company or other borrower which is administered and sold by a
 financial intermediary. A Fund may only invest in loans to issuers in whose
 obligations it may otherwise invest. Loan participation interests may take
 the form of a direct or co-lending relationship with the corporate borrower,
 an assignment of an interest in the loan by a co-lender or another partici-
 pant, or a participation in the seller's share of the loan. When a Fund acts
 as co-lender in connection with a participation interest or when it acquires
 certain participation interests, the Fund will have direct recourse against
 the borrower if the borrower fails to pay scheduled principal and interest.
 In cases where the Fund lacks direct recourse, it will look to the agent
 bank to enforce appropriate credit remedies against the borrower. In these
 cases, the Fund may be subject to delays, expenses and risks that are
 greater than those that would have been involved if the Fund had purchased a
 direct obligation (such as commercial paper) of such borrower. Moreover,
 under the terms of the loan participation, the Fund may be regarded as a
 creditor of the agent bank (rather than of the underlying corporate borrow-
 er), so that the Fund may also be subject to the risk that the agent bank
 may become insolvent.
 
 Preferred Stock, Warrants and Rights. Certain Funds may invest in preferred
 stock, warrants and rights.Preferred stocks are securities that represent an
 ownership interest providing the holder with claims on the issuer's earnings
 and assets before common stock owners but after bond owners. Unlike debt
 securities, the obligations of an issuer of preferred stock, including divi-
 dend and other payment obligations, may not typically be accelerated by the
 holders of such preferred stock on the occurrence of an event of default or
 other non-compliance by the issuer of the preferred stock.
 
 Warrants and other rights are options to buy a stated number of shares of
 common stock at a specified price at any time during the life of the war-
 rant. The holders of warrants and rights have no voting rights, receive no
 dividends and have no rights with respect to the assets of the issuer.

Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

General Investment Management Approach
 
 Goldman Sachs Asset Management, a separate operating division of Goldman,
 Sachs & Co. ("Goldman Sachs"), serves as investment adviser to the Short
 Duration Tax-Free, Government Income, Municipal Income, Core Fixed Income
 and High Yield Funds. Goldman Sachs Funds Management, L.P. serves as invest-
 ment adviser to the Adjustable Rate Government and Short Duration Government
 Funds. Goldman Sachs Asset Management International serves as investment
 adviser to the Global Income Fund. Goldman Sachs Asset Management, Goldman
 Sachs Funds Management, L.P., and Goldman Sachs Asset Management Interna-
 tional are each referred to in this Prospectus as the "Investment Adviser."
 
 Goldman Sachs' Fixed Income Investing Philosophy:
 Active Management Within a Risk-Managed Framework
 The Investment Adviser employs a disciplined, multi-step process to evaluate
 potential investments:
 1. Sector Allocation--The Investment Adviser assesses the relative value of
 different investment sectors (such as U.S. corporate, asset-backed and mort-
 gage-backed securities) to create investment strategies that meet each
 Fund's objectives.
 2. Security Selection--In selecting securities for each Fund, the Investment
 Adviser draws on the extensive resources of Goldman Sachs, including fixed-
 income research professionals.
 3. Yield Curve Strategies--The Investment Adviser adjusts the term structure
 of the Funds based on its expectations of changes in the shape of the yield
 curve while closely controlling the overall duration of the Fund.
 
 The Investment Adviser de-emphasizes interest rate predictions as a means of
 generating incremental return. Instead, the Investment Adviser seeks to add
 value through the selection of particular securities and investment sector
 allocation as described above.
 
 With every fixed-income portfolio, the Investment Adviser applies a team
 approach that emphasizes risk management and capitalizes on Goldman Sachs'
 extensive research capabilities.

 Each of the Funds described in this Prospectus has a target duration. A
 Fund's duration approximates its price sensitivity to changes in interest
 rates. Maturity measures the time until final payment is due; it takes no
 account of the pattern of a security's cash flows over time. In computing
 portfolio duration, a Fund will estimate the duration of obligations that
 are subject to prepayment or redemption by the issuer, taking into account
 the influence of interest rates on prepayments and coupon flows. This method
 of computing duration is known as "option-adjusted" duration. A Fund will
 not be limited as to its maximum weighted average portfolio maturity or the
 maximum stated maturity with respect to individual securities unless other-
 wise noted.
 
 Each Fund also has credit rating requirements for the securities it buys. A
 Fund will deem a security to have met its minimum credit rating requirement
 if the security has the required rating at the time of purchase from at
 least one nationally recognized statistical rating organization ("NRSRO")
 even though it has been rated below the minimum rating by one or more other
 NRSROs. Unrated securities may be purchased by the Funds if they are deter-
 mined by the Investment Adviser to be of comparable quality. If a security
 satisfies a Fund's minimum rating requirement at the time of purchase and is
 subsequently downgraded below such rating, the Fund will not be required to
 dispose of such security. If a downgrade occurs, the Investment Adviser will
 consider what action, including the sale of such security, is in the best
 interests of a Fund and its shareholders.

 The Fund invests, under normal circumstances, at least 65% of its total
 assets in securities issued or guaranteed by the U.S. government, its agen-
 cies, instrumentalities or sponsored enterprises ("U.S. Government Securi-
 ties") that are adjustable rate mortgage pass-through securities and other
 mortgage securities with periodic interest rate resets. The remainder of the
 Fund's assets (up to 35%) may be invested in other U.S. Government Securi-
 ties, including:
 .Fixed rate mortgage pass-through securities
 .Other securities representing an interest in or collateralized by adjust-
  able rate and fixed rate mortgage loans ("Mortgage-Backed Securities")
 .Repurchase agreements collateralized by U.S. Government Securities
 
 Substantially all of the Fund's assets will be invested in U.S. Government
 Securities. 100% of the Fund's portfolio will be invested in U.S. dollar-
 denominated securities.

Goldman Sachs Short Duration Tax-Free Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high level of current income, consistent with relatively
 low volatility of principal, that is exempt from regular federal income tax.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal conditions, at least 80% of its net assets in
 fixed-income securities issued by or on behalf of states, territories and
 possessions of the United States (including the District of Columbia) and
 the political subdivisions, agencies and instrumentalities thereof ("Munici-
 pal Securities"), the interest on which is exempt from regular federal
 income tax (i.e., excluded from gross income for federal income tax purpos-
 es), and is not a tax preference item under the federal alternative minimum
 tax. Under normal circumstances, the Fund's investments in private activity
 bonds and taxable investments will not exceed, in the aggregate, 20% of the
 Fund's net assets. The interest from private activity bonds (including the
 Fund's distributions of such interest) may be a preference item for purposes
 of the federal alternative minimum tax. 100% of the Fund's portfolio will be
 invested in U.S. dollar-denominated securities.

Goldman Sachs Municipal Income Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high level of current income that is exempt from regular
 federal income tax, consistent with preservation of capital.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal circumstances, at least 80% of its net assets
 in Municipal Securities, the interest on which is exempt from regular fed-
 eral income tax (i.e., excluded from gross income for federal income tax
 purposes). The Fund may invest up to 100% of its net assets in private
 activity bonds, the interest from which (including the Fund's distributions
 of such interest) may be a preference item for purposes of the federal
 alternative minimum tax. 100% of the Fund's portfolio will be invested in
 U.S. dollar-denominated securities.

Goldman Sachs Core Fixed Income Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a total return consisting of capital appreciation and income
 that exceeds the total return of the Lehman Brothers Aggregate Bond Index
 (the "Index").
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal circumstances, at least 65% of its total
 assets in fixed-income securities, including U.S. Government Securities,
 corporate debt securities, Mortgage-Backed Securities and asset-backed secu-
 rities. The Fund may also invest in custodial receipts, Municipal Securities
 and convertible securities. The Fund's investments in non-U.S. dollar denom-
 inated obligations will not exceed 25% of its total assets at the time of
 investment, of which 10% may be invested in obligations of issuers in coun-
 tries with emerging markets or economies ("emerging countries"). In pursuing
 its investment objective, the Fund uses the Index as its performance bench-
 mark, but the Fund will not attempt to replicate the Index. The Fund may,
 therefore, invest in securities that are not included in the Index.
 
 Duration (under normal interest rate conditions):
 Target = Lehman Brothers Aggregate Bond Index plus or minus one year
 Maximum = 6 years
 
 Expected Approximate Interest Rate Sensitivity: 5-year U.S. Treasury note
 
 Credit Quality:
 Minimum = BBB or Baa; Minimum for non-U.S. dollar denominated securities =

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
 Goldman Sachs Global Income Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high total return, emphasizing current income, and, to a
 lesser extent, providing opportunities for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests primarily in a portfolio of high quality fixed-income secu-
 rities of U.S. and foreign issuers and enters into transactions in foreign
 currencies. Under normal market conditions, the Fund will:
 .Have at least 30% of its total assets, after considering the effect of cur-
  rency positions, denominated in U.S. dollars
 .Invest in securities of issuers in at least three countries
 .Seek to meet its investment objective by pursuing investment opportunities
  in foreign and domestic fixed-income securities markets and by engaging in
  currency transactions to seek to enhance returns and to seek to hedge its
  portfolio against currency exchange rate fluctuations
 
 The Fund may invest more than 25% of its total assets in the securities of
 corporate and governmental issuers located in each of Canada, Germany, Japan
 and the United Kingdom as well as in the securities of U.S. issuers. Not
 more than 25% of the Fund's total assets will be invested in securities of
 issuers in any other single foreign country. The Fund may also invest up to
 10% of its total assets in issuers in emerging countries.
 
 The fixed-income securities in which the Fund may invest include:
 .U.S. Government Securities and custodial receipts therefor
 .Securities issued or guaranteed by a foreign government or any of its
  political subdivisions, authorities, agencies, instrumentalities or by
  supranational entities
 .Corporate debt securities
 .Certificates of deposit and bankers' acceptances issued or guaranteed by,
  or time deposits maintained at, U.S. or foreign banks (and their branches
  wherever located) having total assets of more than $1 billion
 .Commercial paper
 .Mortgage-Backed Securities and asset-backed securities
 
 The Global Income Fund is "non-diversified" under the Investment Company Act
 of 1940 (the "Act"), and may invest more of its assets in fewer issuers than
 
                                                                               9

Goldman Sachs Global Income Fund continued
 
 "diversified" mutual funds. Therefore, the Global Income Fund may be more
 susceptible to adverse developments affecting any single issuer held in its
 portfolio, and may be more susceptible to greater losses because of these
 developments.

 Goldman Sachs High Yield Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high level of current income and may also consider the
 potential for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal circumstances, at least 65% of its total
 assets in high yield, fixed-income securities rated, at the time of invest-
 ment, below investment grade. Non-investment grade securities are securities
 rated BB, Ba or below by a NRSRO, or, if unrated, determined by the Invest-
 ment Adviser to be of comparable quality. The Fund may invest in all types
 of fixed-income securities, including:
 .Senior and subordinated corporate debt obligations (such as bonds, deben-
  tures, notes and commercial paper)
 .Convertible and non-convertible corporate debt obligations
 .Loan participations
 .Custodial receipts
 .Municipal Securities
 .Preferred stock
 
 The Fund may invest up to 25% of its total assets in obligations of domestic
 and foreign issuers (including securities of issuers located in emerging
 countries) which are denominated in currencies other than the U.S. dollar.
 
 Under normal market conditions, the Fund may invest up to 35% of its total
 assets in investment grade fixed-income securities, including U.S. Govern-
 ment Securities. The Fund may also invest in common stocks, warrants, rights
 and other equity securities, but will generally hold such equity investments
 only when debt or preferred stock of the issuer of such equity securities is
 held by the Fund.
 
 Duration (under normal interest rate conditions):
 Target = Lehman Brothers High Yield Bond Index plus or minus 2.5 years
 Maximum = 7.5 years
 
 Expected Approximate Interest Rate Sensitivity: 6-year U.S. Treasury note

 Credit Quality:
 At least 65% of total assets = BB or Ba or lower at the time of investment
 or, if unrated, determined by the Investment Adviser to be of comparable
 quality
 
 Non-investment grade fixed income securities (commonly known as "junk
 bonds") tend to offer higher yields than higher rated securities with simi-
 lar maturities. Non-investment grade fixed income securities are, however,
 considered speculative and generally involve greater price volatility and
 greater risk of loss of principal and interest than higher rated securities.
 The Fund may purchase the securities of issuers that are in default.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other governmental agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

All Funds:
 
 .Interest Rate Risk--The risk that when interest rates increase, fixed-income
 securities held by a Fund will decline in value. Long-term fixed-income
 securities will normally have more price volatility because of this risk than
 short-term securities.
 .Credit/Default Risk--The risk that an issuer of fixed-income securities held
 by a Fund (which may have low credit ratings) may default on its obligation to
 pay interest and repay principal.
 .Call Risk--The risk that an issuer will exercise its right to pay principal on
 an obligation held by a Fund (such as a Mortgage-Backed Security) earlier than
 expected. This may happen when there is a decline in interest rates. Under
 these circumstances, a Fund may be unable to recoup all of its initial
 investment and will also suffer from having to reinvest in lower yielding
 securities.
 .Extension Risk--The risk that an issuer will exercise its right to pay
 principal on an obligation held by a Fund (such as a Mortgage-Backed Security)
 later than expected. This may happen when there is a rise in interest rates.
 Under these circumstances, the value of the obligation will decrease, and a
 Fund will also suffer from the inability to invest in higher yielding
 securities.
 .Derivatives Risk--The risk that loss may result from a Fund's investments in
 options, futures, swaps, structured securities and other derivative
 investments. These instruments may be leveraged so that small changes may
 produce disproportionate losses to a Fund.
 .U.S. Government Securities Risk--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 .Market Risk--The risk that the value of the securities in which a Fund invests
 may go up or down in response to the prospects of individual companies and/or
 general economic conditions. Price changes may be temporary or last for
 extended periods.
 .Management Risk--The risk that a strategy used by the Investment Adviser may
 fail to produce the intended results.
 .Liquidity Risk--The risk that a Fund will not be able to pay redemption
 proceeds within the time period stated in this Prospectus, because of unusual
 market conditions, an unusually high volume of redemption requests, or other
 reasons. Funds that invest in non-investment grade fixed income securities or
 emerging country issuers will be especially subject to the risk that during
 certain periods the liquidity of particular issuers or industries, or all
 securities within these investment categories, will shrink or disappear
 suddenly and without warning as a result of adverse economic, market or
 political events, or adverse investor perceptions whether or not accurate.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 .Other Risks--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Specific Funds:
 
 .Non-Diversification Risk--The Global Income Fund is non-diversified. The
 Global Income Fund may invest more than 25% of its total assets in the securi-
 ties of corporate and governmental issuers located in each of Canada, Germany,
 Japan and the United Kingdom, as well as in the securities of U.S. issuers.
 Concentration of the Fund's investments in such issuers will subject the Fund,
 to a greater extent than if investments were less concentrated, to losses
 arising from adverse developments affecting those issuers or countries.
 .Foreign Risks--The Core Fixed Income, Global Income and High Yield Funds will
 be subject to risks of loss with respect to their foreign investments that are
 not typically associated with domestic issuers. Loss may result because of
 less foreign government regulation, less public information and less economic,
 political and social stability. Loss may also result from the imposition of
 exchange controls, confiscations and other government restrictions. The Funds
 will also be subject to the risk of negative foreign currency rate fluctua-
 tions. Foreign risks will normally be greatest when a Fund invests in issuers
 located in emerging countries.
 .Emerging Markets Risk--The Core Fixed Income, Global Income and High Yield
 Funds may invest in emerging countries. The securities markets of Asian, Latin
 American, Eastern European, African and other emerging countries are less liq-
 uid, are especially subject to greater price volatility, have smaller market
 capitalizations, have less government regulation and are not subject to as
 extensive and frequent accounting, financial and other reporting requirements
 as the securities markets of more developed countries. Further, investment in
 equity securities of issuers located in Russia and certain other emerging
 countries involves risk of loss resulting from problems in share registration
 and custody and substantial economic and political disruptions. These risks
 are not normally associated with investment in more developed countries.
 ."Junk Bond" Risk--The High Yield Fund will invest in non-investment grade
 fixed-income securities (commonly known as "junk bonds") that are considered
 predominantly speculative by traditional investment standards. Non-investment
 grade fixed-income securities and unrated securities of comparable credit
 quality are subject to the increased risk of an issuer's inability to meet
 principal and interest obligations. These securities may be subject to greater
 price volatility due to such factors as specific corporate developments,
 interest rate sensitivity, negative perceptions of the junk bond markets
 generally and less secondary market liquidity.
 
                                                                              21

 .Tax Risk--The Short Duration Tax-Free and Municipal Income Funds may be more
 adversely impacted by changes in tax rates and policies than the other Funds.
 Because interest income from Municipal Securities is normally not subject to
 regular federal income taxation, the attractiveness of Municipal Securities in
 relation to other investment alternatives is affected by changes in federal
 income tax rates applicable to, or the continuing federal income tax-exempt
 status of, such interest income. Any proposed or actual changes in such rates
 or exempt status, therefore, can significantly affect the demand for and sup-
 ply, liquidity and marketability of Municipal Securities. This could in turn
 affect a Fund's ability to acquire and dispose of Municipal Securities at
 desirable yield and price levels.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Service
 Shares from year to year; and (b) how the average annual returns of a Fund's
 Service Shares compare to those of broad-based securities market indices.
 The bar chart and table assume reinvestment of dividends and distributions.
 A Fund's past performance is not necessarily an indication of how the Fund
 will perform in the future. Performance reflects expense limitations in
 effect. If expense limitations were not in place, a Fund's performance would
 have been reduced.

shares at the end of those periods. The Example also assumes that your invest-
ment has a 5% return each year and that a Fund's operating expenses remain the
same. Although your actual costs may be higher or lower, based on these assump-
tions your costs would be:

 of its asset management affiliates for portfolio decisions and management
 with respect to certain portfolio securities. In addition, the Investment
 Adviser has access to the research and certain proprietary technical models
 developed by Goldman Sachs, and will apply quantitative and qualitative
 analysis in determining the appropriate allocations among categories of
 issuers and types of securities.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to a Fund or limit a Fund's investment activities. Goldman Sachs and its
 affiliates engage in proprietary trading and advise accounts and funds which
 have investment objectives similar to those of the Funds and/or which engage
 in and compete for transactions in the same types of securities, currencies
 and instruments as the Funds. Goldman Sachs and its affiliates will not have
 any obligation to make available any information regarding their proprietary
 activities or strategies, or the activities or strategies used for other
 accounts managed by them, for the benefit of the management of the Funds.
 The results of a Fund's investment activities, therefore, may differ from
 those of Goldman Sachs and its affiliates, and it is possible that a Fund
 could sustain losses during periods in which Goldman Sachs and its affili-
 ates and other accounts achieve significant profits on their trading for
 proprietary or other accounts. In addition, the Funds may, from time to
 time, enter into transactions in which other clients of Goldman Sachs have
 an adverse interest. A Fund's activities may be limited because of regula-
 tory restrictions applicable to Goldman Sachs and its affiliates, and/or
 their internal policies designed to comply with such restrictions.
 
                                                                              41

 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.

Dividends
 
Over the course of the fiscal year, dividends accrued and paid will constitute
all or substantially all of the Funds' net investment income. The Funds also
intend that all net realized capital gains (after taking into account any
available capital loss carryovers) will be declared as a dividend at least
annually. You may choose to have dividends paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 .Shares of the same or an equivalent class of another Goldman Sachs Fund.
 Special restrictions may apply for certain ILA Portfolios. See the Additional
 Statement.
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time before the record date for a
particular dividend or distribution. If you do not indicate any choice, your
dividends and distributions will be reinvested automatically in the applicable
Fund. If cash dividends are elected with respect to the Fund's monthly net
investment income dividends, then cash dividends must also be elected with
respect to the non-long-term capital gains component, if any, of the Fund's
annual dividend.
 
The election to reinvest dividends and distributions in additional shares will
not affect the tax treatment of such dividends and distributions, which will be
treated as received by you and then used to purchase the shares.
 
Dividends from net investment income and distributions from capital gains are
declared and paid as follows:

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Service
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Service Shares Of The Funds?
 Generally, Service Shares may be purchased only through institutions that
 have agreed to provide account administration and personal and account main-
 tenance services to their customers who are the beneficial owners of Service
 Shares. These institutions are called "Service Organizations." Customers of
 a Service Organization will normally give their purchase instructions to the
 Service Organization, and the Service Organization will, in turn, place pur-
 chase orders with Goldman Sachs. Service Organizations will set times by
 which purchase orders and payments must be received by them from their cus-
 tomers. Generally, Service Shares may be purchased from the Funds on any
 business day at their net asset value ("NAV") next determined after receipt
 of an order by Goldman Sachs from a Service Organization. No sales load is
 charged. Purchases of Service Shares must be settled within three business
 days of receipt of a complete purchase order.
 
 Service Organizations are responsible for transmitting purchase orders and
 payments to Goldman Sachs in a timely fashion. Service Organizations should
 place an order with Goldman Sachs at 1-800-621-2550 and either:
 .Wire federal funds to The Northern Trust Company ("Northern"), as
  subcustodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian) on the next business day; or
 .Initiate an Automated Clearing House Network ("ACH") transfer to Northern;
  or
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds--(Name
  of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago, IL
  60606-6372. The Fund will not accept a check drawn on a foreign bank or a
  third-party check.
 
 What Do I Need To Know About Service Organizations?
 Service Organizations may provide the following services in connection with
 their customers' investments in Service Shares:

                                                               SHAREHOLDER GUIDE
 
 
 .Acting, directly or through an agent, as the sole shareholder of record
 .Maintaining account records for customers
 .Processing orders to purchase, redeem or exchange shares for customers
 .Responding to inquiries from prospective and existing shareholders
 .Assisting customers with investment procedures
 
 In addition, some (but not all) Service Organizations are authorized to
 accept, on behalf of Goldman Sachs Trust (the "Trust"), purchase, redemption
 and exchange orders placed by or on behalf of their customers, and may des-
 ignate other intermediaries to accept such orders, if approved by the Trust.
 In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized Service Organization or intermediary on
  a business day, and the order will be priced at the Fund's NAV next deter-
  mined after such acceptance.
 .Service Organizations or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your Service Organization directly to learn whether it is
 authorized to accept orders for the Trust.
 
 Pursuant to a service plan adopted by the Trust's Board of Trustees, Service
 Organizations are entitled to receive payment for their services from the
 Trust of up to 0.50% (on an annualized basis) of the average daily net
 assets of the Service Shares of the Funds, which are attributable to or held
 in the name of the Service Organization for its customers.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Service Organizations and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Service
 Organizations depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses. Additional
 compensation based on sales may, but is currently not expected to, exceed
 0.50% (annualized) of the amount invested.
 
 In addition to Service Shares, each Fund also offers other classes of shares
 to investors. These other share classes are subject to different fees and
 expenses
 
                                                                              45

 (which affect performance), have different minimum investment requirements
 and are entitled to different services than Service Shares. Information
 regarding these other share classes may be obtained from your sales repre-
 sentative or from Goldman Sachs by calling the number on the back cover of
 this Prospectus.
 
 What Is My Minimum Investment In The Funds?
 The Funds do not have any minimum purchase or account requirements with
 respect to Service Shares. A Service Organization may, however, impose a
 minimum amount for initial and subsequent investments in Service Shares, and
 may establish other requirements such as a minimum account balance. A Serv-
 ice Organization may redeem Service Shares held by non-complying accounts,
 and may impose a charge for any special services.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Reject or restrict any purchase or exchange orders by a particular pur-
  chaser (or group of related purchasers). This may occur, for example, when
  a pattern of frequent purchases, sales or exchanges of Service Shares of a
  Fund is evident, or if purchases, sales or exchanges are, or a subsequent
  abrupt redemption might be, of a size that would disrupt the management of
  a Fund.
 
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Service Shares
 is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
     NAV =        - (Liabilities of the Class)
           -------------------------------------------   
           Number of Outstanding Shares of the Class
 
 The Funds' investments are valued based on market quotations, which may be
 furnished by a pricing service or provided by securities dealers. If accu-
 rate quotations are not readily available, the fair value of the Funds'
 investments may be determined based on yield equivalents, a pricing matrix
 or other sources, under valuation procedures established by the Trustees.
 Debt obligations with a remaining maturity of 60 days or less are valued at
 amortized cost.
 
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). This occurs after the determination, if
  any, of income declared as a dividend (except in the case of the Global
  Income Fund).

  Fund shares will not be priced on any day the New York Stock Exchange is
  closed.
 .When you buy shares, you pay the NAV next calculated after the Funds
  receive your order in proper form.
 .When you sell shares, you receive the NAV next calculated after the Funds
  receive your order in proper form.
 
 Note: The time at which transactions and shares are priced and the time by
 which orders must be received may be changed in case of an emergency or if
 regular trading on the New York Stock Exchange is stopped at a time other
 than 4:00 p.m. New York time.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 When Will Shares Be Issued And Dividends Begin To Be Paid?
 Global Income Fund: If a purchase order is received in proper form before
 the Fund's NAV is determined, shares will be issued the same day and will be
 entitled to any dividend declared on or after such purchase date.
 
 For all other Funds:
 .Shares Purchased by Federal Funds Wire or ACH Transfer:
  .If a purchase order in proper form specifies a settlement date and is
   received before the Fund's NAV is determined that day, shares will be
   issued and dividends will begin to accrue on the purchased shares on the
   later of (i) the business day after the purchase order is received; or
   (ii) the day that the federal funds wire or ACH transfer is received by
   State Street.
  .If a purchase order in proper form does not specify a settlement date,
   shares will be issued and dividends will begin to accrue on the business
   day after payment is received.
 
 .Shares Purchased by Check or Federal Reserve Draft:
  .If a purchase order in proper form specifies a settlement date and is
   received before the Fund's NAV is determined that day, shares will be
   issued and dividends will begin to accrue on the business day after pay-
   ment is received.
  .If a purchase order in proper form does not specify a settlement date,
   shares will be issued and dividends will begin to accrue on the business
   day after payment is received.

 HOW TO SELL SHARES
 
 
 How Can I Sell Service Shares Of The Funds?
 Generally, Service Shares may be sold (redeemed) only through Service Orga-
 nizations. Customers of a Service Organization will normally give their
 redemption instructions to the Service Organization, and the Service Organi-
 zation will, in turn, place redemption orders with the Funds. Generally,
 each Fund will redeem its Service Shares upon request on any business day at
 their NAV next determined after receipt of such request in proper form.
 Redemption proceeds may be sent to recordholders by check or by wire (if the
 wire instructions are on record).
 
 A Service Organization may request redemptions in writing or by telephone if
 the optional telephone redemption privilege is not declined on the Account
 Application.

 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request will be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.

 How Are Redemption Proceeds Paid?
 By Wire: The Funds will arrange for redemption proceeds to be wired as fed-
 eral funds to the bank account designated in the recordholder's Account
 Application. The following general policies govern wiring redemption pro-
 ceeds:
 .Redemption proceeds will normally be wired on the next business day in fed-
  eral funds (for a total of one business day delay), but may be paid up to
  three business days following receipt of a properly executed wire transfer
  redemption request. If the shares to be sold were recently paid for by
  check, the Fund will pay the redemption proceeds when the check has
  cleared, which may take up to 15 days. If the Federal Reserve Bank is
  closed on the day that the redemption proceeds would ordinarily be wired,
  wiring the redemption proceeds may be delayed one additional business day.
 .To change the bank designated on your Account Application, you must send
  written instructions signed by an authorized person designated on the
  Account Application to the Transfer Agent.
 .Neither the Trust, nor Goldman Sachs assumes any responsibility for the
  performance of intermediaries or your Service Organization in the transfer
  process. If a problem with such performance arises, you should deal
  directly with such intermediaries or Service Organizations.
 
 By Check: A recordholder may elect in writing to receive redemption proceeds
 by check. Redemption proceeds paid by check will normally be mailed to the
 address of record within three business days of receipt of a properly exe-
 cuted redemption request. If the shares to be sold were recently paid for by
 check, the Fund will pay the redemption proceeds when the check has cleared,
 which may take up to 15 days.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Service Shares of each Fund (other than the Global Income Fund) earn divi-
  dends declared on the day the shares are redeemed.
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Service Organizations are responsible for the timely transmittal of redemp-
  tion requests by their customers to the Transfer Agent. In order to facili-
  tate the timely transmittal of redemption requests, Service Organizations
  may set times by which they must receive redemption requests. Service Orga-
  nizations may also require additional documentation from you.
 
                                                                              49
<PAGE>
 
 
 The Trust reserves the right to:
 .Redeem the Service Shares of any Service Organization whose account balance
  falls below $50 as a result of earlier redemptions. The Funds will not
  redeem Service Shares on this basis if the value of the account falls below
  the minimum account balance solely as a result of market conditions. The
  Fund will give 60 days' prior written notice to allow a Service Organiza-
  tion to purchase sufficient additional shares of the Fund in order to avoid
  such redemption.
 .Redeem the shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 A Service Organization may exchange Service Shares of a Fund at NAV for
 Service Shares of any other Goldman Sachs Fund. The exchange privilege may
 be materially modified or withdrawn at any time upon 60 days' written
 notice.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.

 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types of Reports Will Be Sent Regarding Investments in Service Shares?
 Service Organizations will receive from the Funds annual reports containing
 audited financial statements and semiannual reports. Service Organizations
 will also be provided with a printed confirmation for each transaction in
 their account and a monthly account statement (quarterly in the case of the
 Global Income Fund). A year-to-date statement for accounts will be provided
 upon request made to Goldman Sachs. Service Organizations are responsible
 for providing these or other reports to their customers who are the benefi-
 cial owners of Service Shares in accordance with the rules that apply to
 their accounts with the Service Organizations.
 
                                                                              51

Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Except for exempt-interest dividends paid by the Short Duration Tax-Free and
 Municipal Income Funds as described below, Fund distributions are taxable to
 you as ordinary income (unless your investment is in an IRA or other tax-
 advantaged account) to the extent they are attributable to the Fund's net
 investment income, certain net realized foreign exchange gains, and net
 short-term capital gains. They are taxable as long-term capital gain to the
 extent they are attributable to the Fund's excess of net long-term capital
 gains over net short-term capital losses. The tax status of any distribution
 is the same regardless of how long you have been in the Fund and whether you
 reinvest in additional shares or take the distributions as cash. Certain
 distributions paid by a Fund in January of a given year may be taxable to
 shareholders as if received the prior December 31. The tax status and
 amounts of distribution for each calendar year will be detailed in your
 annual tax statement from the Fund.
 
 At any time, a portion of a Fund's NAV per share may be represented by
 undistributed income or realized or unrealized appreciation of the Fund's
 portfolio securities. Therefore, subsequent distributions on a Fund's shares
 may be taxable to you, even if the NAV of your shares is, as a result,
 reduced below the cost of those shares and the distributions represent a
 return of your purchase price.
 
 The Core Fixed Income, Global Income and High Yield Funds may be subject to
 foreign withholding or other foreign taxes on income or gain from certain
 foreign securities. In general, the Funds may deduct these taxes in comput-
 ing their taxable income. As an alternative, the Global Income Fund (but not
 the other Funds) may make an election to treat a proportionate amount of
 such taxes as constituting a distribution to you, which would allow you
 either to (1) credit such proportionate amount of taxes against your U.S.
 federal income tax liability or (2) take such amount as an itemized deduc-
 tion.
 
 The Short Duration Tax-Free and Municipal Income Funds expect to distribute
 "exempt-interest dividends." These dividends will be exempt income for fed-
 eral income tax purposes. However, distributions, if any, derived from net
 long-term capital gains of the Short Duration Tax-Free and Municipal Income
 Funds will generally be taxable to you as long-term capital gains. Distribu-
 tions, if any, derived from taxable interest income, net short-term capital
 gains and certain net realized foreign exchange gains will be taxable to you
 as ordinary income.

 Interest on indebtedness incurred by you to purchase or carry shares of the
 Short Duration Tax-Free and Municipal Income Funds generally will not be
 deductible for federal income tax purposes.
 
 You should note that exempt-interest dividends paid by the Short Duration
 Tax-Free and Municipal Income Funds may be an item of tax preference for
 purposes of determining your federal alternative minimum tax liability.
 Exempt-interest dividends will also be considered along with other adjusted
 gross income in determining whether any Social Security or railroad retire-
 ment payments received by you are subject to federal income taxes.
 
 If you receive an exempt-interest dividend on shares that are held by you
 for six months or less, any loss on the sale or exchange of the shares will
 be disallowed to the extent of such dividend amount.
 
 There are certain tax requirements that all Funds must follow in order to
 avoid federal taxation. In their efforts to adhere to these requirements,
 the Funds may have to limit their investment activity in some types of
 instruments.
 
 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Fund shares may generate a tax liability (unless
 your investment is in an IRA or other tax-advantaged account). Depending
 upon the purchase or sale price of the shares you sell or exchange, you may
 have a gain or a loss on the transaction.
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Fund, based on the
 difference between your tax basis in the shares and the amount you receive
 for them. (To aid in computing your tax basis, you generally should retain
 your account statements for the periods that you hold shares.) Any loss rec-
 ognized on shares held for six months or less will be treated as a long-term
 capital loss to the extent of any capital gain dividends that were received
 with respect to the shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from any Fund (including the Short Dura-
 tion Tax-Free and Municipal Income Funds) or on the value of the shares held
 by you. More tax information is provided in the Additional Statement. You
 should also consult your own tax adviser for information regarding all tax
 consequences applicable to your investments in the Funds.

Appendix A
Additional Information on Portfolio Risks, Securities and Techniques
 A. General Portfolio Risks
 
 
 The Funds will be subject to the risks associated with fixed-income securi-
 ties. These risks include interest rate risk, credit risk and call/extension
 risk. In general, interest rate risk involves the risk that when interest
 rates decline, the market value of fixed-income securities tends to
 increase. Conversely, when interest rates increase, the market value of
 fixed-income securities tends to decline. Credit risk involves the risk that
 the issuer could default on its obligations, and a Fund will not recover its
 investment. Call risk and extension risk are normally present in adjustable
 rate mortgage loans ("ARMs"), Mortgage-Backed Securities and asset-backed
 securities. For example, homeowners have the option to prepay their mort-
 gages. Therefore, the duration of a security backed by home mortgages can
 either shorten (call risk) or lengthen (extension risk). In general, if
 interest rates on new mortgage loans fall sufficiently below the interest
 rates on existing outstanding mortgage loans, the rate of prepayment would
 be expected to increase. Conversely, if mortgage loan interest rates rise
 above the interest rates on existing outstanding mortgage loans, the rate of
 prepayment would be expected to decrease. In either case, a change in the
 prepayment rate can result in losses to investors.
 
 The Investment Adviser will not consider the portfolio turnover rate a lim-
 iting factor in making investment decisions for a Fund. A high rate of port-
 folio turnover (100% or more) involves correspondingly greater expenses
 which must be borne by a Fund and its shareholders. The portfolio turnover
 rate is calculated by dividing the lesser of the dollar amount of sales or
 purchases of portfolio securities by the average monthly value of a Fund's
 portfolio securities, excluding securities having a maturity at the date of
 purchase of one year or less. See "Financial Highlights" in Appendix B for a
 statement of the Funds' historical portfolio turnover rates.
 
 The following sections provide further information on certain types of secu-
 rities and investment techniques that may be used by the Funds, including
 their associated risks. Additional information is provided in the Additional
 Statement, which is available upon request. Among other things, the Addi-
 tional Statement describes certain fundamental investment restrictions that
 cannot be changed without shareholder approval. You should note, however,
 that all policies not specifically designated as fundamental are non-funda-
 mental and may be changed without share-

                                                                      APPENDIX A
 
 holder approval. If there is a change in a Fund's investment objective, you
 should consider whether that Fund remains an appropriate investment in light
 of your then current financial positions and needs.
 
 B. Other Portfolio Risks
 
 
 Credit Risks. Debt securities purchased by the Funds may include securities
 (including zero coupon bonds) issued by the U.S. government (and its agen-
 cies, instrumentalities and sponsored enterprises), foreign governments,
 domestic and foreign corporations, banks and other issuers. Some of these
 fixed-income securities are described in the next section below. Further
 information is provided in the Additional Statement.
 
 Debt securities rated BBB or higher by Standard & Poor's or Baa or higher by
 Moody's are considered "investment grade." Securities rated BBB or Baa are
 considered medium-grade obligations with speculative characteristics, and
 adverse economic conditions or changing circumstances may weaken their
 issuers' capacity to pay interest and repay principal. A security will be
 deemed to have met a rating requirement if it receives the minimum required
 rating from at least one such rating organization even though it has been
 rated below the minimum rating by one or more other rating organizations, or
 if unrated by such rating organizations, is determined by the Investment
 Adviser to be of comparable credit quality.
 
 Certain Funds may invest in fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) which are commonly referred to as "junk
 bonds." Junk bonds are considered predominantly speculative and may be ques-
 tionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in a Fund's portfolio is downgraded by a rat-
 ing organization, the market price and liquidity of such security may be
 adversely affected.
 
 Risks of Derivative Investments. A Fund's transactions, if any, in options,
 futures, options on futures, swaps, interest rate caps, floors and collars,
 structured securities, inverse floating-rate securities, stripped mortgage-
 backed securities and currency transactions involve additional risk of loss.
 Loss can result from a lack of correlation between changes in the value of
 derivative instruments and the portfolio assets (if any) being hedged, the
 potential illiquidity of the markets for derivative instruments, or the
 risks arising from margin requirements and related lever-
 
                                                                              55
<PAGE>
 
 
 age factors associated with such transactions. The use of these management
 techniques also involves the risk of loss if the Investment Adviser is
 incorrect in its expectation of fluctuations in securities prices, interest
 rates or currency prices. Each Fund may also invest in derivative invest-
 ments for non-hedging purposes (that is, to seek to increase total return),
 which is considered a speculative practice and presents even greater risk of
 loss.
 
 Derivative Mortgage-Backed Securities (such as principal-only ("POs"),
 interest-only ("IOs") or inverse floating rate securities) are particularly
 exposed to call and extension risks. Small changes in mortgage prepayments
 can significantly impact the cash flow and the market value of these securi-
 ties. In general, the risk of faster than anticipated prepayments adversely
 affects IOs, super floaters and premium priced Mortgage-Backed Securities.
 The risk of slower than anticipated prepayments generally adversely affects
 POs, floating-rate securities subject to interest rate caps, support
 tranches and discount priced Mortgage-Backed Securities. In addition, par-
 ticular derivative securities may be leveraged such that their exposure
 (i.e., price sensitivity) to interest rate and/or prepayment risk is
 magnified.
 
 Some floating-rate derivative debt securities can present more complex types
 of derivative and interest rate risks. For example, range floaters are sub-
 ject to the risk that the coupon will be reduced below market rates if a
 designated interest rate floats outside of a specified interest rate band or
 collar. Dual index or yield curve floaters are subject to lower prices in
 the event of an unfavorable change in the spread between two designated
 interest rates.
 
 Risks of Foreign Investments. Foreign investments involve special risks that
 are not typically associated with U.S. dollar denominated or quoted securi-
 ties of U.S. issuers. Foreign investments may be affected by changes in cur-
 rency rates, changes in foreign or U.S. laws or restrictions applicable to
 such investments and changes in exchange control regulations (e.g., currency
 blockage). A decline in the exchange rate of the currency (i.e., weakening
 of the currency against the U.S. dollar) in which a portfolio security is
 quoted or denominated relative to the U.S. dollar would reduce the value of
 the portfolio security. In addition, if the currency in which a Fund
 receives dividends, interest or other payments declines in value against the
 U.S. dollar before such income is distributed as dividends to shareholders
 or converted to U.S. dollars, the Fund may have to sell portfolio securities
 to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts
 
56
<PAGE>
 
                                                                      APPENDIX A
 
 after January 1, 1999 that refer to existing currencies rather than the
 euro; the establishment and maintenance of exchange rates for currencies
 being converted into the euro; the fluctuation of the euro relative to non-
 euro currencies during the transition period from January 1, 1999 to Decem-
 ber 31, 2001 and beyond; whether the interest rate, tax and labor regimes of
 European countries participating in the euro will converge over time; and
 whether the conversion of the currencies of other countries that now are or
 may in the future become members of the European Union ("EU") may have an
 impact on the euro. These or other factors, including political and economic
 risks, could cause market disruptions, and could adversely affect the value
 of securities held by the Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than a U.S. issuer. In addition, there is generally less government
 regulation of foreign markets, companies and securities dealers than in the
 United States. Foreign securities markets may have substantially less volume
 than U.S. securities markets and securities of many foreign issuers are less
 liquid and more volatile than securities of comparable domestic issuers.
 Furthermore, with respect to certain foreign countries, there is a possibil-
 ity of nationalization, expropriation or confiscatory taxation, imposition
 of withholding or other taxes on dividend or interest payments (or, in some
 cases, capital gains), limitations on the removal of funds or other assets
 of the Funds, and political or social instability or diplomatic developments
 which could affect investments in those countries.
 
 Concentration of a Fund's assets in one or a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations by certain Funds involves risks not
 present in debt obligations of corporate issuers. The issuer of the debt or
 the governmental authorities that control the repayment of the debt may be
 unable or unwilling to repay principal or interest when due in accordance
 with the terms of such
 
                                                                              57
<PAGE>
 
 
 debt, and a Fund may have limited recourse to compel payment in the event of
 a default. Periods of economic uncertainty may result in volatility of mar-
 ket prices of sovereign debt, and in turn a Fund's NAV, to a greater extent
 than the volatility inherent in debt obligations of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Risks of Emerging Countries. Certain Funds may invest in securities of
 issuers located in emerging countries. The risks of foreign investment are
 heightened when the issuer is located in an emerging country. Emerging coun-
 tries are generally located in the Asia-Pacific region, Eastern Europe,
 Latin and South America and Africa. A Fund's purchase and sale of portfolio
 securities in certain emerging countries may be constrained by limitations
 as to daily changes in the prices of listed securities, periodic trading or
 settlement volume and/or limitations on aggregate holdings of foreign
 investors. Such limitations may be computed based on the aggregate trading
 volume by or holdings of a Fund, the Investment Adviser, its affiliates and
 their respective clients and other service providers. A Fund may not be able
 to sell securities in circumstances where price, trading or settlement vol-
 ume limitations have been reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, such as Taiwan, it is
 anticipated that a Fund may invest in such countries only through other
 investment funds in such countries.

 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and ethnic, religious and racial disaffec-
 tion, among other factors, have also led to social unrest, violence and/or
 labor unrest in some emerging countries. Unanticipated political or social
 developments may result in sudden and significant investment losses. Invest-
 ing in emerging countries involves greater risk of loss due to expropria-
 tion, nationalization, confiscation of assets and property or the imposition
 of restrictions on foreign investments and on repatriation of capital
 invested.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of those emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 A Fund's investment in emerging countries may also be subject to withholding
 or other taxes, which may be significant and may reduce the return from an
 investment in such country to the Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve a Fund's
 delivery of securities before receipt of payment for their sale. In addi-
 tion, significant delays are common in certain markets in registering the
 transfer of securities. Settlement or registration problems may make it more
 difficult for a Fund to value its portfolio securities and could cause the
 Fund to miss attractive investment opportunities, to have a portion of its
 assets uninvested or to incur losses due to the failure of a counterparty to
 pay for securities the Fund has delivered or the Fund's inability to com-
 plete its contractual obligations. The creditworthiness of the local securi-
 ties firms used by the Funds in emerging countries may not be as sound as
 the creditworthiness of firms used in more developed countries. As a result,
 the Fund may be subject to a greater risk of loss if a securities firm
 defaults in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make a Fund's investments in such countries less liquid and more
 volatile than invest-
 
                                                                              59

 ments in countries with more developed securities markets (such as the
 United States, Japan and most Western European countries). A Fund's invest-
 ments in emerging countries are subject to the risk that the liquidity of
 particular investment, or investments generally, in such countries will
 shrink or disappear suddenly and without warning as a result of adverse eco-
 nomic, market or political conditions or adverse investor perceptions,
 whether or not accurate. Because of the lack of sufficient market liquidity,
 a Fund may incur losses because it will be required to effect sales at a
 disadvantageous time and then only at a substantial drop in price. Invest-
 ments in emerging countries may be more difficult to price precisely because
 of these characteristics and lower trading volumes.
 
 A Fund's use of foreign currency management techniques in emerging countries
 may be limited. Due to the limited market for these instruments in emerging
 countries, the Investment Adviser does not currently anticipate that a sig-
 nificant portion of the Funds' currency exposure in emerging countries, if
 any, will be covered by such instruments.
 
 Risks of Illiquid Securities. Each Fund may invest up to 15% of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
 
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped Mortgage-Backed Securities
 .Repurchase agreements and time deposits with a notice or demand period of
  more than seven days
 .Certain over-the-counter options
 .Certain restricted securities, unless it is determined, based upon a review
  of the trading markets for a specific restricted security, that such
  restricted security is eligible for resale pursuant to Rule 144A under the
  Securities Act of 1933 ("144A Securities") and, therefore, is liquid
 
 Investing in 144A Securities may decrease the liquidity of a Fund's portfo-
 lio to the extent that qualified institutional buyers become for a time
 uninterested in purchasing these restricted securities. The purchase price
 and subsequent valuation of restricted and illiquid securities normally
 reflect a discount, which may be significant, from the market price of com-
 parable securities for which a liquid market exists.
 
 Temporary Investment Risks. Each Fund may, for temporary defensive purposes,
 invest a certain percentage of its total assets in:
 
 .U.S. Government Securities
 .Repurchase agreements collateralized by U.S. Government Securities

 Certain Funds may invest more than 20% of their respective net assets in
 taxable investments and in investment grade securities for temporary defen-
 sive purposes.
 
 C. Portfolio Securities and Techniques
 
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the Funds, including their associ-
 ated risks. Further information is provided in the Additional Statement,
 which is available upon request.
 
 U.S. Government Securities and Related Custodial Receipts. U.S. Government
 Securities include U.S. Treasury obligations and obligations issued or guar-
 anteed by U.S. government agencies, instrumentalities or sponsored enter-
 prises. U.S. Government Securities may be supported by (a) the full faith
 and credit of the U.S. Treasury (such as the Government National Mortgage
 Association ("Ginnie Mae")); (b) the right of the issuer to borrow from the
 U.S. Treasury (such as securities of the Student Loan Marketing Associa-
 tion); (c) the discretionary authority of the U.S. government to purchase
 certain obligations of the issuer (such as the Federal National Mortgage
 Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation
 ("Freddie Mac")); or (d) only the credit of the issuer. U.S. Government
 Securities also include Treasury receipts, zero coupon bonds and other
 stripped U.S. Government Securities, where the interest and principal compo-
 nents of stripped U.S. Government Securities are traded independently.
 
 Interests in U.S. Government Securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S. govern-
 ment.
 
 Mortgage-Backed Securities. Mortgage-Backed Securities represent direct or
 indirect participations in, or are collateralized by and payable from, mort-
 gage loans secured by real property. Mortgage-Backed Securities can be
 backed by either fixed rate mortgage loans or adjustable rate mortgage
 loans, and may be issued by either a governmental or non-governmental enti-
 ty. Privately issued Mortgage-Backed Securities are normally structured with
 one or more types of "credit enhancement." However, these Mortgage-Backed
 Securities typically do not have the same credit standing as U.S. government
 guaranteed Mortgage-Backed Securities.
 
 
                                                                              61
<PAGE>
 
 
 Mortgage-Backed Securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs") and Real Estate Mortgage
 Investment Conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an investor with a specified interest in the cash flow from a
 pool of underlying mortgages or of other Mortgage-Backed Securities. CMOs
 are issued in multiple classes. In most cases, payments of principal are
 applied to the CMO classes in the order of their respective stated maturi-
 ties, so that no principal payments will be made on a CMO class until all
 other classes having an earlier stated maturity date are paid in full. A
 REMIC is a CMO that qualifies for special tax treatment under the Code and
 invests in certain mortgages principally secured by interests in real prop-
 erty and other permitted investments.
 
 Mortgaged-Backed Securities also include stripped Mortgage-Backed Securities
 ("SMBS"), which are derivative multiple class Mortgage-Backed Securities.
 SMBS are usually structured with two different classes: one that receives
 100% of the interest payments and the other that receives 100% of the prin-
 cipal payments from a pool of mortgage loans. The market value of SMBS con-
 sisting entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage loans are generally higher than pre-
 vailing market yields on other Mortgage-Backed Securities because their cash
 flow patterns are more volatile and there is a greater risk that the initial
 investment will not be fully recouped.
 
 Asset-Backed Securities. Asset-backed securities are securities whose prin-
 cipal and interest payments are collateralized by pools of assets such as
 auto loans, credit card receivables, leases, installment contracts and per-
 sonal property. Asset-backed securities are often subject to more rapid
 repayment than their stated maturity date would indicate as a result of the
 pass-through of prepayments of principal on the underlying loans. During
 periods of declining interest rates, prepayment of loans underlying asset-
 backed securities can be expected to accelerate. Accordingly, a Fund's abil-
 ity to maintain positions in such securities will be affected by reductions
 in the principal amount of such securities resulting from prepayments, and
 its ability to reinvest the returns of principal at comparable yields is
 subject to generally prevailing interest rates at that time. Asset-backed
 securities present credit risks that are not presented by Mortgage-Backed
 Securities. This is because asset-backed securities generally do not have
 the benefit of a security interest in collateral that is comparable to mort-
 gage assets. There is the possibility that, in some cases, recoveries on
 repossessed collateral may not be available to support payments on these
 securities. In the event of a default, a Fund may suffer a loss if it cannot
 sell collateral quickly and receive the amount it is owed.

                                                                      APPENDIX A
 
 Municipal Securities. Municipal Securities include bonds, notes, commercial
 paper and other instruments (including participation interests in such secu-
 rities) issued by or on behalf of the states, territories and possessions of
 the United States (including the District of Columbia) and their political
 subdivisions, agencies or instrumentalities, the interest on which, in the
 opinion of bond counsel for the issuers or counsel selected by the Invest-
 ment Adviser, is exempt from regular federal income tax (i.e., excluded from
 gross income for federal income tax purposes but not necessarily exempt from
 federal alternative minimum tax or from state or local taxes). Because of
 their tax-exempt status, the yields and market values of Municipal Securi-
 ties may be more adversely impacted by changes in tax rates and policies
 than taxable fixed-income securities.
 
 Municipal Securities are often issued to obtain funds for various public
 purposes, including the construction of a wide range of public facilities
 such as bridges, highways, housing, hospitals, mass transportation, schools,
 streets and water and sewer works. Municipal Securities include private
 activity bonds, municipal leases, certificates of participation, pre-
 refunded municipal securities and auction rate securities.
 
 The obligations of the issuer to pay the principal of and interest on a
 Municipal Security are subject to the provisions of bankruptcy, insolvency
 and other laws affecting the rights and remedies of creditors, such as the
 Federal Bankruptcy Act, and laws, if any, that may be enacted by Congress or
 state legislatures extending the time for payment of principal or interest
 or imposing other constraints upon the enforcement of such obligations.
 There is also the possibility that, as a result of litigation or other con-
 ditions, the power or ability of the issuer to pay when due the principal of
 or interest on a Municipal Security may be materially affected. Municipal
 lease obligations and certificates of participation are subject to the added
 risk that the governmental lessee will fail to appropriate funds to enable
 it to meet its payment obligations under the lease.
 
 Municipal Securities may be in the form of a tender option bond, which is a
 Municipal Security (generally held pursuant to a custodial arrangement) hav-
 ing a relatively long maturity and bearing interest at a fixed rate substan-
 tially higher than prevailing short-term, tax-exempt rates. The bond is typ-
 ically issued with the agreement of a bank, broker-dealer or other financial
 institution, which grants the security holders the option, at periodic
 intervals, to tender their securities to the institution and receive the
 face value thereof. After payment of a fee to the financial institution that
 provides this option, the security holder effectively holds a demand obliga-
 tion that bears interest at the prevailing short-term, tax-exempt rate. The
 tender option will be taken into account in determining the maturity of the
 tender option bonds and a Fund's average portfolio maturity. There is risk
 that a
 
                                                                              63
<PAGE>
 
 
 Fund will not be considered the owner of a tender option bond for federal
 income tax purposes, and thus will not be entitled to treat such interest as
 exempt from federal income tax. Certain tender option bonds may be illiquid.
 
 Corporate Debt Obligations; Trust Preferred Securities; Convertible Securi-
 ties. Corporate debt obligations include bonds, notes, debentures and other
 obligations of corporations to pay interest and repay principal, and include
 securities issued by banks and other financial institutions. A trust pre-
 ferred or capital security is a long dated bond (for example, 30 years) with
 preferred features. The preferred features are that payment of interest can
 be deferred for a specified period without initiating a default event. The
 securities are generally senior in claim to standard preferred stock but
 junior to other bondholders.
 
 Convertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than non-convertible securities of similar qual-
 ity. Convertible securities in which a Fund invests are subject to the same
 rating criteria as its other investments in fixed-income securities. Con-
 vertible securities have both equity and fixed-income risk characteristics.
 Like all fixed-income securities, the value of convertible securities is
 susceptible to the risk of market losses attributable to changes in interest
 rates. Generally, the market value of convertible securities tends to
 decline as interest rates increase and, conversely, to increase as interest
 rates decline. However, when the market price of the common stock underlying
 a convertible security exceeds the conversion price of the convertible secu-
 rity, the convertible security tends to reflect the market price of the
 underlying common stock. As the market price of the underlying common stock
 declines, the convertible security, like a fixed-income security, tends to
 trade increasingly on a yield basis, and thus may not decline in price to
 the same extent as the underlying common stock.
 
 Foreign Currency Transactions. A Fund may, to the extent consistent with its
 investment policies, purchase or sell foreign currencies on a cash basis or
 through forward contracts. A forward contract involves an obligation to pur-
 chase or sell a specific currency at a future date at a price set at the
 time of the contract. A Fund may engage in foreign currency transactions for
 hedging purposes and to seek to protect against anticipated changes in
 future foreign currency exchange rates. In addition, a Fund also may enter
 into such transactions to seek to increase total return, which is considered
 a speculative practice.
 
 Some Funds may also engage in cross-hedging by using forward contracts in a
 currency different from that in which the hedged security is denominated or
 quoted if the Investment Adviser determines that there is a pattern of cor-
 relation between the two currencies. A Fund may hold foreign currency
 received in con-
 
64

                                                                      APPENDIX A
 
 nection with investments in foreign securities when, in the judgment of the
 Investment Adviser, it would be beneficial to convert such currency into
 U.S. dollars at a later date.
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, a Fund's NAV to fluctuate (when the
 Fund's NAV fluctuates, the value of your shares may go up or down). Currency
 exchange rates also can be affected unpredictably by the intervention of
 U.S. or foreign governments or central banks, or the failure to intervene,
 or by currency controls or political developments in the United States or
 abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are not guaranteed by an exchange or clear-
 inghouse, a default on a contract would deprive a Fund of unrealized prof-
 its, transaction costs or the benefits of a currency hedge or could force
 the Fund to cover its purchase or sale commitments, if any, at the current
 market price.
 
 Structured Securities and Inverse Floaters. Structured securities are secu-
 rities whose value is determined by reference to changes in the value of
 specific currencies, interest rates, commodities, indices or other financial
 indicators (the "Reference") or the relative change in two or more Refer-
 ences. The interest rate or the principal amount payable upon maturity or
 redemption may be increased or decreased depending upon changes in the
 applicable Reference. Structured securities may be positively or negatively
 indexed, so that appreciation of the Reference may produce an increase or
 decrease in the interest rate or value of the security at maturity. In addi-
 tion, changes in the interest rates or the value of the security at maturity
 may be a multiple of changes in the value of the Reference. Consequently,
 structured securities may present a greater degree of market risk than other
 types of fixed-income securities, and may be more volatile, less liquid and
 more difficult to price accurately than less complex securities.
 
 Structured securities include, but are not limited to, inverse floating rate
 debt securities ("inverse floaters"). The interest rate on inverse floaters
 resets in the opposite direction from the market rate of interest to which
 the inverse floater is indexed. An inverse floater may be considered to be
 leveraged to the extent that its interest rate varies by a magnitude that
 exceeds the magnitude of the change in the index rate of interest. The
 higher the degree of leverage of an inverse floater, the greater the vola-
 tility of its market value.
 
                                                                              65
<PAGE>
 
 
 
 Zero Coupon, Deferred Interest, Pay-In-Kind and Capital Appreciation Bonds.
 Zero coupon, deferred interest, pay-in-kind and capital appreciation bonds
 are issued at a discount from their face value because interest payments are
 typically postponed until maturity. Pay-in-kind securities are securities
 that have interest payable by the delivery of additional securities. The
 market prices of these securities generally are more volatile than the mar-
 ket prices of interest-bearing securities and are likely to respond to a
 greater degree to changes in interest rates than interest-bearing securities
 having similar maturities and credit quality.
 
 Mortgage Dollar Rolls. A mortgage dollar roll involves the sale by a Fund of
 securities for delivery in the current month. The Fund simultaneously con-
 tracts with the same counterparty to repurchase substantially similar (same
 type, coupon and maturity) but not identical securities on a specified
 future date. During the roll period, the Fund loses the right to receive
 principal and interest paid on the securities sold. However, the Fund bene-
 fits to the extent of any difference between (a) the price received for the
 securities sold and (b) the lower forward price for the future purchase
 and/or fee income plus the interest earned on the cash proceeds of the secu-
 rities sold. Unless the benefits of a mortgage dollar roll exceed the
 income, capital appreciation and gain or loss due to mortgage prepayments
 that would have been realized on the securities sold as part of the roll,
 the use of this technique will diminish the Fund's performance.
 
 Successful use of mortgage dollar rolls depends upon the Investment Advis-
 er's ability to predict correctly interest rates and mortgage prepayments.
 If the Investment Adviser is incorrect in its prediction, a Fund may experi-
 ence a loss. For financial reporting and tax purposes, the Funds treat mort-
 gage dollar rolls as two separate transactions: one involving the purchase
 of a security and a separate transaction involving a sale. The Funds do not
 currently intend to enter into mortgage dollar rolls that are accounted for
 as a financing and do not treat them as borrowings.
 
 Options on Securities, Securities Indices and Foreign Currencies. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Fund may write
 (sell) covered call and put options and purchase put and call options on any
 securities in which it may invest or on any securities index comprised of
 securities in which it may invest. A Fund that invests in foreign securities
 may also purchase and sell (write) put and call options on foreign curren-
 cies.

                                                                      APPENDIX A
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of the Investment Adviser to manage future price fluctu-
 ations and the degree of correlation between the options and securities (or
 currency) markets. If the Investment Adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in a Fund's investment portfolio, the Fund may incur losses that
 it would not otherwise incur. The use of options can also increase a Fund's
 transaction costs. Options written or purchased by the Funds may be traded
 on either U.S. or foreign exchanges or over-the-counter. Foreign and over-
 the-counter options will present greater possibility of loss because of
 their greater liquidity and credit risks.
 
 Yield Curve Options. Each Fund may enter into options on the yield "spread"
 or differential between two securities. Such transactions are referred to as
 "yield curve" options. In contrast to other types of options, a yield curve
 option is based on the difference between the yields of designated securi-
 ties, rather than the prices of the individual securities, and is settled
 through cash payments. Accordingly, a yield curve option is profitable to
 the holder if this differential widens (in the case of a call) or narrows
 (in the case of a put), regardless of whether the yields of the underlying
 securities increase or decrease.
 
 The trading of yield curve options is subject to all of the risks associated
 with the trading of other types of options. In addition, such options pres-
 ent a risk of loss even if the yield of one of the underlying securities
 remains constant, or if the spread moves in a direction or to an extent
 which was not anticipated.
 
 Futures Contracts and Options on Futures Contracts. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 Government Securities), foreign currencies, securities indices and other
 financial instruments and indices. The Funds may engage in futures transac-
 tions on both U.S. and foreign exchanges.
 
 Each Fund may purchase and sell futures contracts, and purchase and write
 call and put options on futures contracts, in order to seek to increase
 total return or to hedge against changes in interest rates, securities
 prices or, to the extent a Fund invests in foreign securities, currency
 exchange rates, or to otherwise manage their
 
                                                                              67

 term structures, sector selection and durations in accordance with their
 investment objectives and policies. Each Fund may also enter into closing
 purchase and sale transactions with respect to such contracts and options. A
 Fund will engage in futures and related options transactions for bona fide
 hedging purposes as defined in regulations of the Commodity Futures Trading
 Commission or to seek to increase total return to the extent permitted by
 such regulations. A Fund may not purchase or sell futures contracts or pur-
 chase or sell related options to seek to increase total return, except for
 closing purchase or sale transactions, if immediately thereafter the sum of
 the amount of initial margin deposits and premiums paid on the Fund's out-
 standing positions in futures and related options entered into for the pur-
 pose of seeking to increase total return would exceed 5% of the market value
 of the Fund's net assets.
 
 Futures contracts and related options present the following risks:
 .While a Fund may benefit from the use of futures and options on futures,
  unanticipated changes in interest rates, securities prices or currency
  exchange rates may result in poorer overall performance than if the Fund
  had not entered into any futures contracts or options transactions.
 .Because perfect correlation between a futures position and portfolio posi-
  tion that is intended to be protected is impossible to achieve, the desired
  protection may not be obtained and a Fund may be exposed to additional risk
  of loss.
 .The loss incurred by a Fund in entering into futures contracts and in writ-
  ing call options on futures is potentially unlimited and may exceed the
  amount of the premium received.
 .Futures markets are highly volatile and the use of futures may increase the
  volatility of a Fund's NAV.
 .As a result of the low margin deposits normally required in futures trad-
  ing, a relatively small price movement in a futures contract may result in
  substantial losses to a Fund.
 .Futures contracts and options on futures may be illiquid, and exchanges may
  limit fluctuations in futures contract prices during a single day.
 .Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to the Fund at the time of entering into the
 transaction. A forward commitment involves entering into a contract to pur-
 chase or sell securities for a fixed price at a future date beyond the cus-
 tomary settlement period.

                                                                      APPENDIX A
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although a Fund will generally
 purchase securities on a when-issued or forward commitment basis with the
 intention of acquiring securities for its portfolio, a Fund may dispose of
 when-issued securities or forward commitments prior to settlement if the
 Investment Adviser deems it appropriate.
 
 Lending of Portfolio Securities. Securities lending involves the lending of
 securities owned by a Fund to financial institutions such as certain broker-
 dealers. The borrowers are required to secure their loans continuously with
 cash, cash equivalents, U.S. Government Securities or letters of credit in
 an amount at least equal to the market value of the securities loaned. Cash
 collateral may be invested in cash equivalents. If the Investment Adviser
 determines to make securities loans, the value of the securities loaned may
 not exceed 33 1/3% of the value of the total assets of a Fund (including the
 loan collateral).
 
 A Fund may lend its securities to increase its income. A Fund may, however,
 experience delay in the recovery of its securities if the institution with
 which it has engaged in a portfolio loan transaction breaches its agreement
 with the Fund.
 
 Repurchase Agreements. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Fund may enter into repurchase agreements
 with dealers in U.S. Government Securities and member banks of the Federal
 Reserve System which furnish collateral at least equal in value or market
 price to the amount of their repurchase obligation. Some Funds may also
 enter into repurchase agreements involving certain foreign government secu-
 rities.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund are less than the repurchase price and the
 Fund's cost associated with delay and enforcement of the repurchase agree-
 ment. In addition, in the event of bankruptcy of the seller, a Fund could
 suffer additional losses if a court determines that the Fund's interest in
 the collateral is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to a Fund's
 shareholders. In addition, certain Funds, together with other registered
 investment companies having advisory agreements with the Investment Adviser
 or any of its affiliates, may transfer uninvested cash balances into a sin-
 gle joint account, the daily aggregate balance of which will be invested in
 one or more repurchase agreements.
 
                                                                              69
<PAGE>
 
 
 
 Borrowings and Reverse Repurchase Agreements. The Funds can borrow money
 from banks and enter into reverse repurchase agreements with banks and other
 financial institutions in amounts not exceeding one-third of its total
 assets. Reverse repurchase agreements involve the sale of securities held by
 a Fund subject to the Fund's agreement to repurchase them at a mutually
 agreed upon date and price (including interest). These transactions may be
 entered into as a temporary measure for emergency purposes or to meet
 redemption requests. Reverse repurchase agreements may also be entered into
 when the Investment Adviser expects that the interest income to be earned
 from the investment of the transaction proceeds will be greater than the
 related interest expense. Borrowings and reverse repurchase agreements
 involve leveraging. If the securities held by a Fund decline in value while
 these transactions are outstanding, the NAV of the Fund's outstanding shares
 will decline in value by proportionately more than the decline in value of
 the securities. In addition, reverse repurchase agreements involve the risk
 that the interest income earned by a Fund (from the investment of the pro-
 ceeds) will be less than the interest expense of the transaction, that the
 market value of the securities sold by a Fund will decline below the price
 the Fund is obligated to pay to repurchase the securities, and that the
 securities may not be returned to the Fund.
 
 Interest Rate Swaps, Mortgage Swaps, Credit Swaps, Currency Swaps and Inter-
 est Rate Caps, Floors and Collars. Interest rate swaps involve the exchange
 by a Fund with another party of their respective commitments to pay or
 receive interest, such as an exchange of fixed-rate payments for floating
 rate payments. Mortgage swaps are similar to interest rate swaps in that
 they represent commitments to pay and receive interest. The notional princi-
 pal amount, however, is tied to a reference pool or pools of mortgages.
 Credit swaps involve the receipt of floating or fixed rate payments in
 exchange for assuming potential credit losses of an underlying security.
 Credit swaps give one party to a transaction the right to dispose of or
 acquire an asset (or group of assets), or the right to receive or make a
 payment from the other party, upon the occurrence of specified credit
 events. Currency swaps involve the exchange of the parties' respective
 rights to make or receive payments in specified currencies. The purchase of
 an interest rate cap entitles the purchaser, to the extent that a specified
 index exceeds a predetermined interest rate, to receive payment of interest
 on a notional principal amount from the party selling such interest rate
 cap. The purchase of an interest rate floor entitles the purchaser, to the
 extent that a specified index falls below a predetermined interest rate, to
 receive payments of interest on a notional principal amount from the party
 selling the interest rate floor. An interest rate collar is the combination
 of a cap and a floor that preserves a certain return within a predetermined
 range of interest rates.

 Each Fund may enter into swap transactions for hedging purposes or to seek
 to increase total return. The use of interest rate, mortgage, credit and
 currency swaps, as well as interest rate caps, floors and collars, is a
 highly specialized activity which involves investment techniques and risks
 different from those associated with ordinary portfolio securities transac-
 tions. If the Investment Adviser is incorrect in its forecasts of market
 value, interest rates and currency exchange rates, the investment perfor-
 mance of a Fund would be less favorable than it would have been if these
 investment techniques were not used.
 
 Other Investment Companies. A Fund may invest in securities of other invest-
 ment companies subject to the limitations prescribed by the Act. These limi-
 tations include a prohibition on any Fund acquiring more than 3% of the vot-
 ing shares of any other investment company, and a prohibition on investing
 more than 5% of a Fund's total assets in securities of any one investment
 company or more than 10% of its total assets in securities of all investment
 companies. A Fund will indirectly bear its proportionate share of any man-
 agement fees and other expenses paid by such other investment companies.
 Such other investment companies will have investment objectives, policies
 and restrictions substantially similar to those of the acquiring Fund and
 will be subject to substantially the same risks.
 
 Non-Investment Grade Fixed-Income Securities. Non-investment grade fixed-
 income securities and unrated securities of comparable credit quality (com-
 monly known as "junk bonds") are considered predominantly speculative by
 traditional investment standards. In some cases, these obligations may be
 highly speculative and have poor prospects for reaching investment grade
 standing. Non-investment grade fixed-income securities are subject to the
 increased risk of an issuer's inability to meet principal and interest obli-
 gations. These securities, also referred to as high yield securities, may be
 subject to greater price volatility due to such factors as specific corpo-
 rate developments, interest rate sensitivity, negative perceptions of the
 junk bond markets generally and less secondary market liquidity.
 
 Non-investment grade fixed-income securities are often issued in connection
 with a corporate reorganization or restructuring or as part of a merger,
 acquisition, takeover or similar event. They are also issued by less estab-
 lished companies seeking to expand. Such issuers are often highly leveraged
 and generally less able than more established or less leveraged entities to
 make scheduled payments of principal and interest in the event of adverse
 developments or business conditions.
 
 The market value of non-investment grade fixed-income securities tends to
 reflect individual corporate developments to a greater extent than that of
 higher rated securities which react primarily to fluctuations in the general
 level of interest rates. As a result, a Fund's ability to achieve its
 investment objectives may
 
                                                                              71
<PAGE>
 
 
 depend to a greater extent on the Investment Adviser's judgment concerning
 the creditworthiness of issuers than funds which invest in higher-rated
 securities. Issuers of non-investment grade fixed-income securities may not
 be able to make use of more traditional methods of financing and their abil-
 ity to service debt obligations may be affected more adversely than issuers
 of higher-rated securities by economic downturns, specific corporate devel-
 opments or the issuer's inability to meet specific projected business fore-
 casts. Negative publicity about the junk bond market and investor percep-
 tions regarding lower rated securities, whether or not based on fundamental
 analysis, may depress the prices for such securities.
 
 A holder's risk of loss from default is significantly greater for non-
 investment grade fixed-income securities than is the case for holders of
 other debt securities because such non-investment grade securities are gen-
 erally unsecured and are often subordinated to the rights of other creditors
 of the issuers of such
 securities. Investment by a Fund in defaulted securities poses additional
 risk of loss should nonpayment of principal and interest continue in respect
 of such securities. Even if such securities are held to maturity, recovery
 by a Fund of its initial investment and any anticipated income or apprecia-
 tion is uncertain.
 
 The secondary market for non-investment grade fixed-income securities is
 concentrated in relatively few market makers and is dominated by institu-
 tional investors, including mutual funds, insurance companies and other
 financial institutions. Accordingly, the secondary market for such securi-
 ties is not as liquid as, and is more volatile than, the secondary market
 for higher-rated securities. In addition, market trading volume for high
 yield fixed-income securities is generally lower and the secondary market
 for such securities could shrink or disappear suddenly and without warning
 as a result of adverse market or economic conditions, independent of any
 specific adverse changes in the condition of a particular issuer. Because of
 the lack of sufficient market liquidity, a Fund may incur losses because it
 will be required to effect sales at a disadvantageous time and then may at a
 substantial drop in price. These factors may have an adverse effect on the
 market price and a Fund's ability to dispose of particular portfolio invest-
 ments. A less liquid secondary market also may make it more difficult for a
 Fund to obtain precise valuations of the high yield securities in its port-
 folio.
 
 Credit ratings issued by credit rating agencies are designed to evaluate the
 safety of principal and interest payments of rated securities. They do not,
 however, evaluate the market value risk of non-investment grade securities
 and, therefore, may not fully reflect the true risks of an investment. In
 addition, credit rating agencies may or may not make timely changes in a
 rating to reflect changes in the economy or in the conditions of the issuer
 that affect the market value of the security. Consequently, credit ratings
 are used only as a preliminary indicator of investment

 quality. Investments in non-investment grade and comparable unrated obliga-
 tions will be more dependent on the Investment Adviser's credit analysis
 than would be the case with investments in investment-grade debt obliga-
 tions.
 
 Loan Participations. A loan participation is an interest in a loan to a U.S.
 or foreign company or other borrower which is administered and sold by a
 financial intermediary. A Fund may only invest in loans to issuers in whose
 obligations it may otherwise invest. Loan participation interests may take
 the form of a direct or co-lending relationship with the corporate borrower,
 an assignment of an interest in the loan by a co-lender or another partici-
 pant, or a participation in the seller's share of the loan. When a Fund acts
 as co-lender in connection with a participation interest or when it acquires
 certain participation interests, the Fund will have direct recourse against
 the borrower if the borrower fails to pay scheduled principal and interest.
 In cases where the Fund lacks direct recourse, it will look to the agent
 bank to enforce appropriate credit remedies against the borrower. In these
 cases, the Fund may be subject to delays, expenses and risks that are
 greater than those that would have been involved if the Fund had purchased a
 direct obligation (such as commercial paper) of such borrower. Moreover,
 under the terms of the loan participation, the Fund may be regarded as a
 creditor of the agent bank (rather than of the underlying corporate borrow-
 er), so that the Fund may also be subject to the risk that the agent bank
 may become insolvent.
 
 Preferred Stock, Warrants and Rights. Certain Funds may invest in preferred
 stock, warrants and rights. Preferred stocks are securities that represent
 an ownership interest providing the holder with claims on the issuer's earn-
 ings and assets before common stock owners but after bond owners. Unlike
 debt securities, the obligations of an issuer of preferred stock, including
 dividend and other payment obligations, may not typically be accelerated by
 the holders of such preferred stock on the occurrence of an event of default
 or other non-compliance by the issuer of the preferred stock.
 
 Warrants and other rights are options to buy a stated number of shares of
 common stock at a specified price at any time during the life of the war-
 rant. The holders of warrants and rights have no voting rights, receive no
 dividends and have no rights with respect to the assets of the issuer.

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

General Investment Management Approach
 
 Goldman Sachs Asset Management, a separate operating division of Goldman,
 Sachs & Co. ("Goldman Sachs"), serves as investment adviser to the Short
 Duration Tax-Free, Government Income, Municipal Income, Core Fixed Income
 and High Yield Funds. Goldman Sachs Funds Management, L.P. serves as invest-
 ment adviser to the Adjustable Rate Government and Short Duration Government
 Funds. Goldman Sachs Asset Management International serves as investment
 adviser to the Global Income Fund. Goldman Sachs Asset Management, Goldman
 Sachs Funds Management, L.P., and Goldman Sachs Asset Management Interna-
 tional are each referred to in this Prospectus as the "Investment Adviser."
 
 Goldman Sachs' Fixed Income Investing Philosophy:
 Active Management Within a Risk-Managed Framework
 The Investment Adviser employs a disciplined, multi-step process to evaluate
 potential investments:
 1. Sector Allocation--The Investment Adviser assesses the relative value of
 different investment sectors (such as U.S. corporate, asset-backed and mort-
 gage-backed securities) to create investment strategies that meet each
 Fund's objectives.
 2. Security Selection--In selecting securities for each Fund, the Investment
 Adviser draws on the extensive resources of Goldman Sachs, including fixed-
 income research professionals.
 3. Yield Curve Strategies--The Investment Adviser adjusts the term structure
 of the Funds based on its expectations of changes in the shape of the yield
 curve while closely controlling the overall duration of the Fund.
 
 The Investment Adviser de-emphasizes interest rate predictions as a means of
 generating incremental return. Instead, the Investment Adviser seeks to add
 value through the selection of particular securities and investment sector
 allocation as described above.
 
 With every fixed-income portfolio, the Investment Adviser applies a team
 approach that emphasizes risk management and capitalizes on Goldman Sachs'
 extensive research capabilities.

 Each of the Funds described in this Prospectus has a target duration. A
 Fund's duration approximates its price sensitivity to changes in interest
 rates. Maturity measures the time until final payment is due; it takes no
 account of the pattern of a security's cash flows over time. In computing
 portfolio duration, a Fund will estimate the duration of obligations that
 are subject to prepayment or redemption by the issuer, taking into account
 the influence of interest rates on prepayments and coupon flows. This method
 of computing duration is known as "option-adjusted" duration. A Fund will
 not be limited as to its maximum weighted average portfolio maturity or the
 maximum stated maturity with respect to individual securities unless other-
 wise noted.
 
 Each Fund also has credit rating requirements for the securities it buys. A
 Fund will deem a security to have met its minimum credit rating requirement
 if the security has the required rating at the time of purchase from at
 least one nationally recognized statistical rating organization ("NRSRO")
 even though it has been rated below the minimum rating by one or more other
 NRSROs. Unrated securities may be purchased by the Funds if they are deter-
 mined by the Investment Adviser to be of comparable quality. If a security
 satisfies a Fund's minimum rating requirement at the time of purchase and is
 subsequently downgraded below such rating, the Fund will not be required to
 dispose of such security. If a downgrade occurs, the Investment Adviser will
 consider what action, including the sale of such security, is in the best
 interests of a Fund and its shareholders.

Fund Investment Objectives and Strategies
 
Goldman Sachs Adjustable Rate Government Fund
 
 INVESTMENT OBJECTIVE
 
 The Fund seeks to provide a high level of current income, consistent with
 low volatility of principal.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 The Fund invests, under normal circumstances, at least 65% of its total
 assets in securities issued or guaranteed by the U.S. government, its agen-
 cies, instrumentalities or sponsored enterprises ("U.S. Government Securi-
 ties") that are adjustable rate mortgage pass-through securities and other
 mortgage securities with periodic interest rate resets. The remainder of the
 Fund's assets (up to 35%) may be invested in other U.S. Government Securi-
 ties, including:

 . Fixed rate mortgage pass-through securities

 . Other securities representing an interest in or collateralized by adjust-
   able rate and fixed rate mortgage loans ("Mortgage-Backed Securities")

 . Repurchase agreements collateralized by U.S. Government Securities
 
 Substantially all of the Fund's assets will be invested in U.S. Government
 Securities. 100% of the Fund's portfolio will be invested in U.S. dollar-
 denominated securities.
 
 Duration (under normal interest rate conditions):
 Target = Six-Month to One-Year U.S. Treasury Security
 Maximum = 2 years
 
 Expected Approximate Interest Rate Sensitivity: 9-month U.S. Treasury bill
 
 Credit Quality: U.S. Government Securities and repurchase agreements collat-
 eralized by such securities
 
 Benchmarks: Six-Month and One-Year U.S. Treasury Security
 
                                                                               3

Goldman Sachs Short Duration Government Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high level of current income and secondarily, in seeking
 current income, may also consider the potential for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal market conditions, at least 65% of its total
 assets in U.S. Government Securities and in repurchase agreements collater-
 alized by such securities. Substantially all of the Fund's assets will be
 invested in U.S. Government Securities. 100% of the Fund's portfolio will be
 invested in U.S. dollar-denominated securities.
 
 Duration (under normal interest rate conditions):
 Target = Two-Year U.S. Treasury Security plus or minus 0.5 years
 Maximum = 3 years

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
Goldman Sachs Short Duration Tax-Free Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high level of current income, consistent with relatively
 low volatility of principal, that is exempt from regular federal income tax.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal conditions, at least 80% of its net assets in
 fixed-income securities issued by or on behalf of states, territories and
 possessions of the United States (including the District of Columbia) and
 the political subdivisions, agencies and instrumentalities thereof ("Munici-
 pal Securities"), the interest on which is exempt from regular federal
 income tax (i.e., excluded from gross income for federal income tax purpos-
 es), and is not a tax preference item under the federal alternative minimum
 tax. Under normal circumstances, the Fund's investments in private activity
 bonds and taxable investments will not exceed, in the aggregate, 20% of the
 Fund's net assets. The interest from private activity bonds (including the
 Fund's distributions of such interest) may be a preference item for purposes
 of the federal alternative minimum tax. 100% of the Fund's portfolio will be
 invested in U.S. dollar-denominated securities.
 
 Duration (under normal interest rate conditions):
 Target = Lehman Brothers Three-Year Municipal Bond Index plus or minus 0.5
 years
 Maximum = 4 years
 
 Expected Approximate Interest Rate Sensitivity: 3-year municipal bond

 The Fund invests, under normal circumstances, at least 65% of its total
 assets in U.S. Government Securities and in repurchase agreements collater-
 alized by such securities. The remainder of the Fund's assets may be
 invested in non-government securities such as privately issued Mortgage-
 Backed Securities, asset-backed securities and corporate securities. 100% of
 the Fund's portfolio will be invested in U.S. dollar-denominated securities.

 Target = Lehman Brothers Mutual Fund Government/Mortgage Index plus or minus
 1 year
 Maximum = 6 years
 
 Expected Approximate Interest Rate Sensitivity: 5-year U.S. Treasury note

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
Goldman Sachs Municipal Income Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high level of current income that is exempt from regular
 federal income tax, consistent with preservation of capital.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal circumstances, at least 80% of its net assets
 in Municipal Securities, the interest on which is exempt from regular fed-
 eral income tax (i.e., excluded from gross income for federal income tax
 purposes). The Fund may invest up to 100% of its net assets in private
 activity bonds, the interest from which (including the Fund's distributions
 of such interest) may be a preference item for purposes of the federal
 alternative minimum tax. 100% of the Fund's portfolio will be invested in
 U.S. dollar-denominated securities.
 
 Duration (under normal interest rate conditions):
 Target = Lehman Brothers 15-Year Municipal Bond Index plus or minus one year
 Maximum = 12 years
 
 Expected Approximate Interest Rate Sensitivity: 15-year municipal bond
 
 Credit Quality:
 Minimum = BBB/Baa at the time of purchase; Weighted Average = AA or Aa Secu-
 rities will either be rated by a NRSRO or, if unrated, determined by the
 Investment Adviser to be of comparable quality
 
 Benchmark: Lehman Brothers 15-Year Municipal Bond Index

Goldman Sachs Core Fixed Income Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a total return consisting of capital appreciation and income
 that exceeds the total return of the Lehman Brothers Aggregate Bond Index
 (the "Index").
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal circumstances, at least 65% of its total
 assets in fixed-income securities, including U.S. Government Securities,
 corporate debt securities, Mortgage-Backed Securities and asset-backed secu-
 rities. The Fund may also invest in custodial receipts, Municipal Securities
 and convertible securities. The Fund's investments in non-U.S. dollar denom-
 inated obligations will not exceed 25% of its total assets at the time of
 investment, of which 10% may be invested in obligations of issuers in coun-
 tries with emerging markets or economies ("emerging countries"). In pursuing
 its investment objective, the Fund uses the Index as its performance bench-
 mark, but the Fund will not attempt to replicate the Index. The Fund may,
 therefore, invest in securities that are not included in the Index.
 
 Duration (under normal interest rate conditions):
 Target = Lehman Brothers Aggregate Bond Index plus or minus one year
 Maximum = 6 years
 
 Expected Approximate Interest Rate Sensitivity: 5-year U.S. Treasury note
 
 Credit Quality:
 Minimum = BBB or Baa; Minimum for non-U.S. dollar denominated securities =
 AA or Aa
 
 Securities will either be rated by a NRSRO or, if unrated, determined by the
 Investment Adviser to be of comparable quality

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high total return, emphasizing current income, and, to a

 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests primarily in a portfolio of high quality fixed-income secu-
 rities of U.S. and foreign issuers and enters into transactions in foreign
 currencies. Under normal market conditions, the Fund will:

 . Have at least 30% of its total assets, after considering the effect of cur-
   rency positions, denominated in U.S. dollars

 . Invest in securities of issuers in at least three countries

 . Seek to meet its investment objective by pursuing investment opportunities
   in foreign and domestic fixed-income securities markets and by engaging in
   currency transactions to seek to enhance returns and to seek to hedge its
   portfolio against currency exchange rate fluctuations
 
 The Fund may invest more than 25% of its total assets in the securities of
 corporate and governmental issuers located in each of Canada, Germany, Japan
 and the United Kingdom as well as in the securities of U.S. issuers. Not
 more than 25% of the Fund's total assets will be invested in securities of
 issuers in any other single foreign country. The Fund may also invest up to
 10% of its total assets in issuers in emerging countries.
 
 The fixed-income securities in which the Fund may invest include:

 . U.S. Government Securities and custodial receipts therefor

 . Securities issued or guaranteed by a foreign government or any of its
   political subdivisions, authorities, agencies, instrumentalities or by
   supranational entities

 . Corporate debt securities

 . Certificates of deposit and bankers' acceptances issued or guaranteed by,
   or time deposits maintained at, U.S. or foreign banks (and their branches
   wherever located) having total assets of more than $1 billion

 . Commercial paper

 . Mortgage-Backed Securities and asset-backed securities
 
 The Global Income Fund is "non-diversified" under the Investment Company Act
 of 1940 (the "Act"), and may invest more of its assets in fewer issuers than
 
                                                                               9

Goldman Sachs Global Income Fund continued
 
 "diversified" mutual funds. Therefore, the Global Income Fund may be more
 susceptible to adverse developments affecting any single issuer held in its
 portfolio, and may be more susceptible to greater losses because of these
 developments.

Goldman Sachs High Yield Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high level of current income and may also consider the
 potential for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal circumstances, at least 65% of its total
 assets in high yield, fixed-income securities rated, at the time of invest-
 ment, below investment grade. Non-investment grade securities are securities
 rated BB, Ba or below by a NRSRO, or, if unrated, determined by the Invest-
 ment Adviser to be of comparable quality. The Fund may invest in all types
 of fixed-income securities, including:

 . Senior and subordinated corporate debt obligations (such as bonds, deben-
   tures, notes and commercial paper)

 . Convertible and non-convertible corporate debt obligations

 . Loan participations

 . Custodial receipts

 . Municipal Securities

 . Preferred stock
 
 The Fund may invest up to 25% of its total assets in obligations of domestic
 and foreign issuers (including securities of issuers located in emerging
 countries) which are denominated in currencies other than the U.S. dollar.
 
 Under normal market conditions, the Fund may invest up to 35% of its total
 assets in investment grade fixed-income securities, including U.S. Govern-
 ment Securities. The Fund may also invest in common stocks, warrants, rights
 and other equity securities, but will generally hold such equity investments
 only when debt or preferred stock of the issuer of such equity securities is
 held by the Fund.
 
 Duration (under normal interest rate conditions):
 Target = Lehman Brothers High Yield Bond Index plus or minus 2.5 years
 Maximum = 7.5 years
 
 Expected Approximate Interest Rate Sensitivity: 6-year U.S. Treasury note

 Credit Quality:
 At least 65% of total assets = BB or Ba or lower at the time of investment
 or, if unrated, determined by the Investment Adviser to be of comparable
 quality
 
 Non-investment grade fixed income securities (commonly known as "junk
 bonds") tend to offer higher yields than higher rated securities with simi-
 lar maturities. Non-investment grade fixed income securities are, however,
 considered speculative and generally involve greater price volatility and
 greater risk of loss of principal and interest than higher rated securities.
 The Fund may purchase the securities of issuers that are in default.

 bonds) held by the Fund during the fiscal year ended October 31, 1998:

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other governmental agency. The following

your investment. None of the Funds should be relied upon as a complete invest-

All Funds:
 
 . Interest Rate Risk--The risk that when interest rates increase, fixed-income
  securities held by a Fund will decline in value. Long-term fixed-income
  securities will normally have more price volatility because of this risk than
  short-term securities.

 . Credit/Default Risk--The risk that an issuer of fixed-income securities held
  by a Fund (which may have low credit ratings) may default on its obligation to
  pay interest and repay principal.

 . Call Risk--The risk that an issuer will exercise its right to pay principal on
  an obligation held by a Fund (such as a Mortgage-Backed Security) earlier than
  expected. This may happen when there is a decline in interest rates. Under
  these circumstances, a Fund may be unable to recoup all of its initial
  investment and will also suffer from having to reinvest in lower yielding
  securities.
 . Extension Risk--The risk that an issuer will exercise its right to pay
  principal on an obligation held by a Fund (such as a Mortgage-Backed Security)
  later than expected. This may happen when there is a rise in interest rates.
  Under these circumstances, the value of the obligation will decrease, and a
  Fund will also suffer from the inability to invest in higher yielding
  securities.
 . Derivatives Risk--The risk that loss may result from a Fund's investments in
  options, futures, swaps, structured securities and other derivative
  investments. These instruments may be leveraged so that small changes may
  produce disproportionate losses to a Fund.

 . U.S. Government Securities Risk--The risk that the U.S. government will not
  provide financial support to U.S. government agencies, instrumentalities or
  sponsored enterprises if it is not obligated to do so by law.

 . Market Risk--The risk that the value of the securities in which a Fund invests
  may go up or down in response to the prospects of individual companies and/or
  general economic conditions. Price changes may be temporary or last for
  extended periods.

 . Management Risk--The risk that a strategy used by the Investment Adviser may
  fail to produce the intended results.
 . Liquidity Risk--The risk that a Fund will not be able to pay redemption
  proceeds within the time period stated in this Prospectus, because of unusual
  market conditions, an unusually high volume of redemption requests, or other
  reasons. Funds that invest in non-investment grade fixed income securities or
  emerging country issuers will be especially subject to the risk that during
  certain periods the liquidity of particular issuers or industries, or all
  securities within these investment categories, will shrink or disappear
  suddenly and without warning as a result of adverse economic, market or
  political events, or adverse investor perceptions whether or not accurate.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 . Other Risks--Each Fund is subject to other risks, such as the risk that its
  operations, or the value of its portfolio securities, will be disrupted by the
  "Year 2000 Problem."
 
Specific Funds:
 
 . Non-Diversification Risk--The Global Income Fund is non-diversified. The
  Global Income Fund may invest more than 25% of its total assets in the securi-
  ties of corporate and governmental issuers located in each of Canada, Germany,
  Japan and the United Kingdom, as well as in the securities of U.S. issuers.
  Concentration of the Fund's investments in such issuers will subject the Fund,
  to a greater extent than if investments were less concentrated, to losses
  arising from adverse developments affecting those issuers or countries.

 . Foreign Risks--The Core Fixed Income, Global Income and High Yield Funds will
  be subject to risks of loss with respect to their foreign investments that are
  not typically associated with domestic issuers. Loss may result because of
  less foreign government regulation, less public information and less economic,
  political and social stability. Loss may also result from the imposition of
  exchange controls, confiscations and other government restrictions. The Funds
  will also be subject to the risk of negative foreign currency rate fluctua-
  tions. Foreign risks will normally be greatest when a Fund invests in issuers
  located in emerging countries.

 . Emerging Markets Risk--The Core Fixed Income, Global Income and High Yield
  Funds may invest in emerging countries. The securities markets of Asian, Latin
  American, Eastern European, African and other emerging countries are less liq-
  uid, are especially subject to greater price volatility, have smaller market
  capitalizations, have less government regulation and are not subject to as
  extensive and frequent accounting, financial and other reporting requirements
  as the securities markets of more developed countries. Further, investment in
  equity securities of issuers located in Russia and certain other emerging
  countries involves risk of loss resulting from problems in share registration
  and custody and substantial economic and political disruptions. These risks
  are not normally associated with investment in more developed countries.

 . "Junk Bond" Risk--The High Yield Fund will invest in non-investment grade
  fixed-income securities (commonly known as "junk bonds") that are considered
  predominantly speculative by traditional investment standards. Non-investment
  grade fixed-income securities and unrated securities of comparable credit
  quality are subject to the increased risk of an issuer's inability to meet
  principal and interest obligations. These securities may be subject to
  greater price volatility due to such factors as specific corporate
  developments, interest rate sensitivity, negative perceptions of the junk
  bond markets generally and less secondary market liquidity.
                                                                             21
<PAGE>
 
 
 . Tax Risk--The Short Duration Tax-Free and Municipal Income Funds may be more
  adversely impacted by changes in tax rates and policies than the other Funds.
  Because interest income from Municipal Securities is normally not subject to
  regular federal income taxation, the attractiveness of Municipal Securities
  in relation to other investment alternatives is affected by changes in
  federal income tax rates applicable to, or the continuing federal income tax-
  exempt status of, such interest income. Any proposed or actual changes in
  such rates or exempt status, therefore, can significantly affect the demand
  for and sup-ply, liquidity and marketability of Municipal Securities. This
  could in turn affect a Fund's ability to acquire and dispose of Municipal
  Securities at desirable yield and price levels.
  
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Class A
 Shares from year to year; and (b) how the average annual returns of a Fund's
 Class A, B and C Shares* compare to those of broad-based securities market
 indices. The bar chart and table assume reinvestment of dividends and dis-
 tributions. A Fund's past performance is not necessarily an indication of
 how the Fund will perform in the future. The average annual total return
 calculation reflects a maximum initial sales charge of 1.5% for Class A
 Shares of Adjustable Rate Government Fund; 2.0% for Class A Shares of Short
 Duration Government and Short Duration Tax-Free Funds; and 4.5% for Class A
 Shares of Government Income, Municipal Income, Core Fixed Income, Global
 Income and High Yield Funds; the assumed contingent deferred sales charge
 ("CDSC") for Class B Shares (2% maximum declining to 0% after three years
 for the Short Duration Government and Short Duration Tax-Free Funds and 5%
 maximum declining to 0% after six years for the Government Income, Municipal
 Income, Core Fixed Income, Global Income and High Yield Funds); and the
 assumed CDSC for Class C Shares (1% if redeemed within 12 months of pur-
 chase). The bar chart does not reflect the sales loads applicable to Class A
 Shares. If the sales loads were reflected, returns would be less. Perfor-
 mance reflects expense limitations in effect. If expense limitations were
 not in place, a Fund's performance would have been reduced.
 
 
 
 * The Adjustable Rate Government Fund does not currently, but may in the
   future, offer Class B and Class C Shares.

Fund Fees and Expenses continued
 
 
/1/The maximum sales charge is a percentage of the offering price. Except with
respect to direct purchases of the Adjustable Rate Government Fund, a CDSC of
1% is imposed on certain redemptions (within 18 months of purchase) of Class A
Shares sold without an initial sales charge as part of an investment of $1 mil-
lion or more ($500,000 in the case of the Short Duration Government and Short
Duration Tax-Free Funds).
/2/The maximum CDSC is a percentage of the lesser of the net asset value
("NAV") at the time of redemption or the NAV when the shares were originally
purchased.
/3/With the exception of the Short Duration Government Fund and the Short Dura-
tion Tax-Free Fund, a CDSC is imposed upon Class B Shares redeemed within six
years of purchase at a rate of 5% in the first year, declining to 1% in the
sixth year, and eliminated thereafter. With respect to the Short Duration Gov-
ernment Fund and Short Duration Tax-Free Fund, a CDSC is imposed on shares
redeemed within three years of purchase at a rate of 2.0% in the first year,
declining to 1% in the third year, and eliminated thereafter.
/4/A CDSC of 1% is imposed on Class C Shares redeemed within 12 months of pur-
chase.
/5/A transaction fee of $7.50 may be charged for redemption proceeds paid by
wire. In addition to free reinvestments of dividends and distributions in
shares of other Goldman Sachs Funds or shares of the Goldman Sachs Institu-
tional Liquid Assets Portfolios (the "ILA Portfolios") and free automatic
exchanges pursuant to the Automatic Exchange Program, six free exchanges are
permitted in each 12-month period. A fee of $12.50 may be charged for each sub-
sequent exchange during such period.
/6/The Funds' annual operating expenses have been restated to reflect current
fees.
/7/The Investment Adviser has voluntarily agreed not to impose a portion of the
management fee on the Short Duration Tax-Free, Government Income, Municipal
Income and Global Income Funds equal to 0.05%, 0.11%, 0.05% and 0.25%, respec-
tively. As a result of fee waivers, the current management fees of the Short
Duration Tax-Free, Government Income, Municipal Income and Global Income Funds
are 0.35%, 0.54%, 0.50% and 0.65%, respectively, of such Funds' average daily
net assets. The waivers may be terminated at any time at the option of the
Investment Adviser.
/8/Goldman Sachs has voluntarily agreed not to impose a portion of the distri-
bution and service fees attributable to Class B Shares of the Short Duration
Government and Short Duration Tax-Free Funds equal to 0.15%. Current distribu-
tion and service fees for such Class B Shares are payable at the rate of 0.85%
of average daily net assets.
/9/"Other Expenses" include transfer agency fees equal to 0.19% of the average
daily net assets of each Fund's Class A, B and C Shares, plus all other ordi-
nary expenses not detailed above. The Investment Adviser has voluntarily agreed
to reduce or limit "Other Expenses" of each Fund (excluding management fees,
distribution and service fees, transfer agency fees, taxes, interest and bro-
kerage fees and litigation, indemnification and other extraordinary expenses)
to the following percentages of each Fund's average daily net assets:

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the waivers and expense limitations) with the cost of investing
in other mutual funds. The Example assumes that you invest $10,000 in Class A,
B or C Shares of a Fund for the time periods indicated and then redeem all of
your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that a Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

The hypothetical example assumes that a CDSC will not apply to redemptions of
Class A Shares within the first 18 months. Class B Shares convert to Class A
Shares eight years after purchase; therefore, Class A expenses are used in the
hypothetical example after year eight.
Certain institutions that sell Fund shares and/or their salespersons may
receive other compensation in connection with the sale and distribution of
Class A, Class B and Class C Shares for services to their customers' accounts
and/or the Funds. For additional information regarding such compensation, see

 GSAM is a separate operating division of Goldman Sachs, which registered as
 an investment adviser in 1981. GSFM, a registered investment adviser since
 1990, is a Delaware limited partnership which is an affiliate of Goldman
 Sachs. GSAMI, a member of the Investment Management Regulatory Organization
 Limited since 1990 and a registered investment adviser since 1991, is an
 affiliate of Goldman Sachs. As of December 31, 1998, GSAM, GSFM and GSAMI,
 together with their affiliates, acted as investment adviser or distributor
 for assets in excess of $195 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser makes the investment decisions
 for the Funds and places purchase and sale orders for the Funds' portfolio
 transactions in U.S. and foreign markets. As permitted by applicable law,
 these orders may be directed to any brokers, including Goldman Sachs and its
 affiliates. While the Investment Adviser is ultimately responsible for the
 management of the Funds, it is able to draw upon the research and expertise
 of its asset management affiliates for portfolio decisions and management
 with respect to certain portfolio securities. In addition, the Investment
 Adviser has access to the research and certain proprietary technical models
 developed by Goldman Sachs, and will apply quantitative and qualitative
 analysis in determining the appropriate allocations among categories of
 issuers and types of securities.

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to a Fund or limit a Fund's investment activities. Goldman Sachs and its
 affiliates engage in proprietary trading and advise accounts and funds which
 have investment objectives similar to those of the Funds and/or which engage
 in and compete for transactions in the same types of securities, currencies
 and instruments as the Funds. Goldman Sachs and its affiliates will not have
 any obligation to make available any information regarding their proprietary
 activities or strategies, or the activities or strategies used for other
 accounts managed by them, for the benefit of the management of the Funds.
 The results of a Fund's investment activities, therefore, may differ from
 those of Goldman Sachs and its affiliates, and it is possible that a Fund
 could sustain losses during periods in which Goldman Sachs and its affili-
 ates and other accounts achieve significant profits on their trading for
 proprietary or other accounts. In addition, the Funds may, from time to
 time, enter into transactions in which other clients of Goldman Sachs have
 an adverse interest. A Fund's activities may be limited because of regula-
 tory restrictions applicable to Goldman Sachs and its affiliates, and/or
 their internal policies designed to comply with such restrictions.

 YEAR 2000
 
 
Many computer systems were designed using only two digits to signify the year
(for example, "98" for "1998"). On January 1, 2000, if these computer systems
are not corrected, they may incorrectly interpret "00" as the year "1900"
rather than the year "2000," leading to computer shutdowns or errors (commonly
known as the "Year 2000 Problem"). To the extent these systems conduct forward-
looking calculations, these computer problems may occur prior to January 1,
2000. Like other investment companies and financial and business organizations,
the Funds could be adversely affected in their ability to process securities
trades, price securities, provide shareholder account services and otherwise
conduct normal business operations if the Investment Adviser or other Fund
service providers do not adequately address this problem in a timely manner.
 
In order to address the Year 2000 Problem, the Investment Adviser has taken the
following measures:

 . The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 . The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
Currently, the Investment Adviser does not anticipate that the transition to
the 21st century will have any material impact on its ability to continue to
service the Funds at current levels.
 
In addition, the Investment Adviser has undertaken measures to appropriately
take into account available information concerning the Year 2000 preparedness
of the issuers of securities held by the Funds. The Investment Adviser may
obtain such Year 2000 information from various sources which the Investment
Adviser believes to be reliable, including the issuers' public regulatory fil-
ings. However, the Investment Adviser is not in a position to verify the accu-
racy or completeness of such information.
 
At this time, however, no assurance can be given that the actions taken by the
Investment Adviser and the Funds' other service providers will be sufficient to
avoid any adverse effect on the Funds due to the Year 2000 Problem.
 
                                                                              49

Dividends
 
Over the course of the fiscal year, dividends accrued and paid will constitute
all or substantially all of the Funds' net investment income. The Funds also
intend that all net realized capital gains (after taking into account any
available capital loss carryovers) will be declared as a dividend at least
annually. You may choose to have dividends paid in:

 . Cash

 . Additional shares of the same class of the same Fund

 . Shares of the same or an equivalent class of another Goldman Sachs Fund.
  Special restrictions may apply for certain ILA Portfolios. See the Additional
  Statement.
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time before the record date for a
particular dividend or distribution. If you do not indicate any choice, your
dividends and distributions will be reinvested automatically in the applicable
Fund. If cash dividends are elected with respect to the Fund's monthly net
investment income dividends, then cash dividends must also be elected with
respect to the non-long-term capital gains component, if any, of the Fund's
annual dividend.
 
The election to reinvest dividends and distributions in additional shares will
not affect the tax treatment of such dividends and distributions, which will be
treated as received by you and then used to purchase the shares.
 
Dividends from net investment income and distributions from capital gains are
declared and paid as follows:

 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 . Refuse to open an account if you fail to (i) provide a social security num-
   ber or other taxpayer identification number; or (ii) certify that such num-
   ber is correct (if required to do so under applicable law).
 . Reject or restrict any purchase or exchange order by a particular purchaser
   (or group of related purchasers). This may occur, for example, when a pat-
   tern of frequent purchases, sales or exchanges of shares of a Fund is evi-
   dent, or if purchases, sales or exchanges are, or a subsequent abrupt
   redemption might be, of a size that would disrupt management of a Fund.
 . Modify or waive the minimum investment amounts.
 . Modify the manner in which shares are offered.
 . Modify the sales charge rates applicable to future purchases of shares.
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange shares is deter-
 mined by a Fund's NAV and share class. Each class calculates its NAV as fol-
 lows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = -------------------------------------------
            Number of Outstanding Shares of the Class
 
 The Funds' investments are valued based on market quotations, which may be
 furnished by a pricing service or provided by securities dealers. If accu-
 rate quotations are not readily available, the fair value of the Funds'
 investments may be determined based on yield equivalents, a pricing matrix
 or other sources, under valuation procedures established by the Trustees.
 Debt obligations with a remaining maturity of 60 days or less are valued at
 amortized cost.
 
 . NAV per share of each share class is calculated by the Fund's custodian on
   each business day as of the close of regular trading on the New York Stock
   Exchange (normally 4:00 p.m. New York time). This occurs after the determi-
   nation, if any, of the income to be declared as a dividend (except in the
   case of the Global Income Fund). Fund shares will not be priced on any day
   the New York Stock Exchange is closed.

 . When you buy shares, you pay the NAV next calculated after the Funds
   receive your order in proper form, plus any applicable sales charge.

 . When you sell shares, you receive the NAV next calculated after the Funds
   receive your order in proper form, less any applicable CDSC.
 
 
                                                                              53
<PAGE>
 
 
 Note: The time at which transactions and shares are priced and the time by
 which orders must be received may be changed in case of an emergency or if
 regular trading on the New York Stock Exchange is stopped at a time other
 than 4:00 p.m. New York time.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 COMMON QUESTIONS ABOUT THE PURCHASE OF CLASS A SHARES
 
 
 What Is The Offering Price Of Class A Shares?
 The offering price of Class A Shares of each Fund is the next determined NAV
 per share plus an initial sales charge paid to Goldman Sachs at the time of
 purchase of shares. The sales charge varies depending upon the amount you
 purchase. In some cases, described below, the initial sales charge may be
 eliminated altogether, and the offering price will be the NAV per share. The
 current sales charges and commissions paid to Authorized Dealers for Class A
 Shares of the Government Income, Municipal Income, Core Fixed Income, Global
 Income and High Yield Funds are as follows:

   * Dealer's allowance may be changed periodically. During special promo-
     tions, the entire sales charge may be allowed to Authorized Dealers.
     Authorized Dealers to whom substantially the entire sales charge is
     allowed may be deemed to be "underwriters" under the Securities Act of
     1933.
  ** No sales charge is payable at the time of purchase of Class A Shares of
     $1 million ($500,000 in the case of the Short Duration Government and
     Short Duration Tax-Free Funds) or more, but a CDSC of 1% may be imposed
     in the event of certain redemptions within 18 months of purchase.
 *** The Distributor pays a one-time commission to Authorized Dealers who
     initiate or are responsible for purchases of $1 million or more of
     shares of the Funds ($500,000 in the case of the Short Duration Govern-
     ment and Short Duration Tax-Free Funds) equal to 1.00% of the amount
     under $3 million, 0.50% of the next $2 million, and 0.25% thereafter.
     The Distributor may also pay, with respect to all or a portion of the
     amount purchased, a commission in accordance with the foregoing schedule
     to Authorized Dealers who initiate or are responsible for purchases of
     $500,000 or more by certain pension and profit sharing plans, pension
     funds and other company-sponsored benefit plans investing in the Funds
     which satisfy the criteria set forth below in "When Are Class A Shares
     Not Subject To A Sales Load" or $1 million ($500,000 in the case of the
     Short Duration Government and Short Duration Tax-Free Funds) or more by
     certain "wrap" accounts. Purchases by such plans will be made at NAV
     with no initial sales charge, but if all of the shares held are redeemed
     within 18 months after the end of the calendar month in which such pur-
     chase was made, a CDSC of 1% may be imposed upon the plan sponsor or the
     third party administrator. In addition, Authorized Dealers will remit to
     the Distributor such payments received in connection with "wrap"
     accounts in the event that shares are redeemed within 18 months after
     the end of the calendar month in which the purchase was made.

 What Else Do I Need To Know About Class A Shares' CDSC?
 Purchases of $1 million ($500,000 in the case of the Short Duration Govern-
 ment and Short Duration Tax-Free Funds) or more of Class A Shares will be
 made at NAV with no initial sales charge. However, if you redeem shares
 within 18 months after the end of the calendar month in which the purchase
 was made, excluding any period of time in which the shares were exchanged
 into and remained invested in an equivalent class of an ILA Portfolio, a
 CDSC of 1% may be imposed. The CDSC may not be imposed if your Authorized
 Dealer enters into an agreement with the Distributor to return all or an
 applicable prorated portion of its commission to the Distributor. The CDSC
 is waived on redemptions in certain circumstances. See "In What Situations
 May The CDSC On Class A, B Or C Shares Be Waived Or Reduced?" below.
 
 When Are Class A Shares Not Subject To A Sales Load?
 Class A Shares of the Funds may be sold at NAV without payment of any sales
 charge to the following individuals and entities:
 . Goldman Sachs, its affiliates or their respective officers, partners,
   directors or employees (including retired employees and former partners),
   any partnership of which Goldman Sachs is a general partner, any Trustee or
   officer of the Trust and designated family members of any of these individ-
   uals;

 . Qualified retirement plans of Goldman Sachs;

 . Trustees or directors of investment companies for which Goldman Sachs or an
   affiliate acts as sponsor;

 . Any employee or registered representative of any Authorized Dealer or their
   respective spouses, children and parents;

 . Banks, trust companies or other types of depository institutions investing
   for their own account or investing for discretionary or non-discretionary
   accounts;

 . Any state, county or city, or any instrumentality, department, authority or
   agency thereof, which is prohibited by applicable investment laws from pay-
   ing a sales charge or commission in connection with the purchase of shares
   of a Fund;

 . Pension and profit sharing plans, pension funds and other company-sponsored
   benefit plans that:

   . Buy shares of Goldman Sachs Funds worth $500,000 or more; or

   . Have 100 or more eligible employees at the time of purchase; or

   . Certify that they expect to have annual plan purchases of shares of
     Goldman Sachs Funds of $200,000 or more; or

   . Are provided administrative services by certain third-party administra-
     tors that have entered into a special service arrangement with Goldman
     Sachs relating to such plans; or

   . Effective May 1, 1999, have at the time of purchase aggregate assets of
     at least $2,000,000.

 . "Wrap" accounts for the benefit of clients of broker-dealers, financial
   institutions or financial planners, provided they have entered into an
   agreement with GSAM specifying aggregate minimums and certain operating
   policies and standards;
 
 . Registered investment advisers investing for accounts for which they
   receive asset-based fees;
 
 . Accounts over which GSAM or its advisory affiliates have investment discre-
   tion; or
 
 . Shareholders receiving distributions from a qualified retirement plan
   invested in the Goldman Sachs Funds and reinvesting such proceeds in a
   Goldman Sachs IRA.
 
 You must certify eligibility for any of the above exemptions on your Account
 Application and notify the Fund if you no longer are eligible for the exemp-
 tion. The Fund will grant you an exemption subject to confirmation of your
 entitlement. You may be charged a fee if you effect your transactions
 through a broker or agent.
 
 How Can The Sales Charge On Class A Shares Be Reduced?
 . Right of Accumulation: When buying Class A Shares in Goldman Sachs Funds,
   your current aggregate investment determines the initial sales load you pay.
   You may qualify for reduced sales charges when the current market value of
   holdings (shares at current offering price), plus new purchases, reaches
   $100,000 or more in the case of the Government Income, Municipal Income,
   Core Fixed Income, Global Income and High Yield Funds; $250,000 or more in
   the case of the Short Duration Government and Short Duration Tax-Free Funds;
   and $500,000 or more in the case of the Adjustable Rate Govern-ment Fund.
   Class A Shares of any of the Goldman Sachs Funds may be combined under the
   Right of Accumulation. To qualify for a reduced sales load, you or your
   Authorized Dealer must notify the Fund's Transfer Agent at the time of
   investment that a quantity discount is applicable. Use of this service is
   subject to a check of appropriate records. The Additional Statement has more
   information about the Right of Accumulation.
   
 . Statement of Intention: You may obtain a reduced sales charge by means of a
   written Statement of Intention which expresses your non-binding commitment
   to invest in the aggregate $100,000 or more within a period of 13 months in
   the case of the Government Income, Municipal Income, Core Fixed Income,
   Global Income and High Yield Funds; $250,000 or more in the case of the
   Short Duration Government and Short Duration Tax-Free Funds; and $500,000 or
   more in the case of the Adjustable Rate Government Fund. Any investments you
   make during the period receive the discounted sales load based on the full
   amount of your investment commitment. If the investment commitment of the
   Statement
                                                                             57

  of Intention is not met prior to the expiration of the 13-month period, the
  entire amount will be subject to the higher applicable sales charge. The
  Additional Statement has more information about the Statement of Intention.
 
 COMMON QUESTIONS ABOUT THE PURCHASE OF CLASS B SHARES
 
 
 What Is The Offering Price Of Class B Shares?
 You may purchase Class B Shares of the Funds (other than the Adjustable Rate
 Government Fund) at the next determined NAV without an initial sales charge.
 However, Class B Shares redeemed within six years (three years in the case
 of the Short Duration Government and Short Duration Tax-Free Funds) of pur-
 chase will be subject to a CDSC at the rates shown in the table below based
 on how long you held your shares.
 
 The CDSC schedule is as follows:

</TABLE>
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or part to defray the Distributor's expenses related to providing dis-
 tribution-related services to the Funds in connection with the sale of Class
 B Shares, including the payment of compensation to Authorized Dealers. A
 commission equal to 2% in the case of the Short Duration Government and
 Short Duration Tax-Free Funds and 4% in the case of all other Funds of the
 amount invested is paid to Authorized Dealers.
 
 What Should I Know About The Automatic Conversion Of Class B Shares?
 Class B Shares of a Fund will automatically convert into Class A Shares of
 the same Fund at the end of the calendar quarter that is eight years after
 the purchase date.
 
 If you acquire Class B Shares of a Fund by exchange from Class B Shares of
 another Goldman Sachs Fund, your Class B Shares will convert into Class A
 Shares of such Fund based on the date of the initial purchase and the CDSC
 schedule of that purchase.

 If you acquire Class B Shares through reinvestment of distributions, your
 Class B Shares will convert into Class A Shares based on the date of the
 initial purchase of the shares on which the distribution was paid.
 
 The conversion of Class B Shares to Class A Shares will not occur at any
 time the Funds are advised that such conversions may constitute taxable
 events for federal tax purposes, which the Funds believe is unlikely. If
 conversions do not occur as a result of possible taxability, Class B Shares
 would continue to be subject to higher expenses than Class A Shares for an
 indeterminate period.
 
 A COMMON QUESTION ABOUT THE PURCHASE OF CLASS C SHARES
 
 
 What Is The Offering Price Of Class C Shares?
 You may purchase Class C Shares of the Funds (other than the Adjustable Rate
 Government Fund) at the next determined NAV without paying an initial sales
 charge. However, if you redeem Class C Shares within 12 months of purchase,
 a CDSC of 1% will be deducted from the redemption proceeds.
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or in part to defray the Distributor's expenses related to providing
 distribution-related services to the Funds in connection with the sale of
 Class C Shares, including the payment of compensation to Authorized Dealers.
 An amount equal to 1% of the amount invested is paid by the Distributor to
 Authorized Dealers.
 
 COMMON QUESTIONS APPLICABLE TO THE PURCHASE OF CLASS A, B
 AND C SHARES
 
 
 When Will Shares Be Issued And Dividends Begin To Be Paid?
 Global Income Fund: If a purchase order is received in proper form before
 the Fund's NAV is determined, shares will be issued the same day and will be
 entitled to any dividend declared which have record dates on or after such
 purchase date.
 
 For all other Funds:
 . Shares Purchased by Federal Funds Wire or ACH Transfer:
   . If a purchase order in proper form specifies a settlement date and is
     received before the Fund's NAV is determined, shares will be issued and
     dividends will begin to accrue on the purchased shares on the later of (i)
     the business day after the purchase order is received; or (ii) the day
     that the federal funds wire or ACH transfer is received by State Street.

                                                                             59
<PAGE>
 
 . If a purchase order in proper form does not specify a settlement date,
   shares will be issued and dividends will begin to accrue on the business
   day after payment is received.
 
 . Shares Purchased by Check or Federal Reserve Draft:
 . If a purchase order in proper form specifies a settlement date and is
   received before the Fund's NAV is determined, shares will be issued and
   dividends will begin to accrue on the business day after payment is
   received.
 . If a purchase order in proper form does not specify a settlement date,
   shares will be issued and dividends will being to accrue on the business
   day after payment is received.
 
 What Else Do I Need To Know About The CDSC On Class A, B Or C Shares?
 . The CDSC is based on the lesser of the NAV of the shares at the time of
   redemption or the original offering price (which is the original NAV).
   . No CDSC is charged on shares acquired from reinvested dividends or capi-
     tal gains distributions.
 . No CDSC is charged on the per share appreciation of your account over the
   initial purchase price.
 . When counting the number of months since a purchase of Class B or Class C
   Shares was made, all payments made during a month will be combined and
   considered to have been made on the first day of that month.
 . To keep your CDSC as low as possible, each time you place a request to sell
   shares, the Funds will first sell any shares in your account that do not
   carry a CDSC and then the shares in your account that have been held the
   longest.
 
 In What Situations May The CDSC On Class A, B Or C Shares Be Waived Or
 Reduced?
 The CDSC on Class A, Class B and Class C Shares that are subject to a CDSC
 may be waived or reduced if the redemption relates to:
 . Retirement distributions or loans to participants or beneficiaries from
   pension and profit sharing plans, pension funds and other company-sponsored
   benefit plans (each a "Retirement Plan");
 . The death or disability (as defined in Section 72(m)(7) of the Internal
   Revenue Code of 1986, as amended (the "Code")) of a participant or benefi-
   ciary in a Retirement Plan;

                                                               SHAREHOLDER GUIDE
 
 . Hardship withdrawals by a participant or beneficiary in a Retirement Plan;

 . Satisfying the minimum distribution requirements of the Code;

 . Establishing "substantially equal periodic payments" as described under
   Section 72(t)(2) of the Code;

 . The separation from service by a participant or beneficiary in a Retirement
   Plan;

 . The death or disability (as defined in Section 72(m)(7) of the Code) of a
   shareholder if the redemption is made within one year of the event;

 . Excess contributions distributed from a Retirement Plan;

 . Distributions from a qualified Retirement Plan invested in the Goldman
   Sachs Funds which are being rolled over to a Goldman Sachs IRA; or

 . Redemption proceeds which are to be reinvested in accounts or non-regis-
   tered products over which GSAM or its advisory affiliates have investment
   discretion.
 
 In addition, Class A, B and C Shares subject to a systematic withdrawal plan
 may be redeemed without a CDSC. The Funds reserve the right to limit such
 redemptions, on an annual basis, to 12% each of the value of your Class B
 and C Shares and 10% of the value of your Class A Shares.
 
 How Do I Decide Whether To Buy Class A, B Or C Shares?
 The decision as to which Class to purchase depends on the amount you invest,
 the intended length of the investment and your personal situation.
 
 . Class A Shares. If you are making an investment of $100,000 or more that
   qualifies for a reduced sales charge, you should consider purchasing Class
   A Shares.

 . Class B Shares. If you plan to hold your investment for at least six years
   (three years in the case of the Short Duration Government and Short Dura-
   tion Tax-Free Funds) and would prefer not to pay an initial sales charge,
   you might consider purchasing Class B Shares. By not paying a front-end
   sales charge, your entire investment in Class B Shares is available to work
   for you from the time you make your initial investment. However, the dis-
   tribution and service fee paid by Class B Shares will cause your Class B
   Shares (until conversion to Class A Shares) to have a higher expense ratio
   and thus, lower performance and lower dividend payments (to the extent div-
   idends are paid) than Class A Shares.

   A maximum purchase limitation of $250,000 in the aggregate normally
   applies to Class B Shares.

 . Class C Shares. If you are unsure of the length of your investment or plan
   to hold your investment for less than six years and would prefer not to pay
   an initial sales charge, you may prefer Class C Shares. By not paying a
   front-end
 
                                                                              61
<PAGE>
 
  sales charge, your entire investment in Class C Shares is available to work
  for you from the time you make your initial investment. However, the dis-
  tribution and service fee paid by Class C Shares will cause your Class C
  Shares to have a higher expense ratio, and thus lower performance and lower
  dividend payments (to the extent dividends are paid) than Class A Shares
  (or Class B Shares after conversion to Class A Shares).
  Although Class C Shares are subject to a CDSC for only 12 months, Class C
  Shares do not have the conversion feature applicable to Class B Shares and
  your investment will therefore pay higher distribution fees indefinitely.
  A maximum purchase limitation of $1,000,000 ($500,000 in the case of the
  Short Duration Government and Short Duration Tax-Free Funds) in the aggre-
  gate normally applies to purchases of Class C Shares.
 
 Note: Authorized Dealers may receive different compensation for selling
 Class A, Class B or Class C Shares.
  In addition to Class A, Class B and Class C Shares, each Fund also offers
  other classes of shares to investors. These other share classes are sub-
  ject to different fees and expenses (which affect performance), have dif-
  ferent minimum investment requirements and are entitled to different serv-
  ices. Information regarding these other share classes may be obtained from
  your sales representative or from Goldman Sachs by calling the number on
  the back cover of this Prospectus.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Class A, Class B And Class C Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. Each Fund will redeem its shares upon request on
 any business day at the NAV next determined after receipt of such request in
 proper form, subject to any applicable CDSC. You may request that redemption
 proceeds be sent to you by check or by wire (if the wire instructions are on
 record). Redemptions may be requested in writing or by telephone.

                     Sachs brokerage account are not subject to the
                     $50,000 limit
 -----------------------------------------------------------------------
</TABLE>
 
 When Do I Need A Signature Guarantee To Redeem Shares?
 A signature guarantee is required if:
 . You are requesting in writing to redeem shares in an amount over $50,000;
 . You would like the redemption proceeds sent to an address that is not your
   address of record; or
 . You would like to change the bank designated on your Account Application.
 
 A signature guarantee is designed to protect you, the Funds and Goldman
 Sachs from fraud. You may obtain a signature guarantee from a bank, securi-
 ties broker or dealer, credit union having the authority to issue signature
 guarantees, savings and loan association, building and loan association,
 cooperative bank, federal savings bank or association, national securities
 exchange, registered securities association or clearing agency, provided
 that such institution satisfies the standards established by Goldman Sachs.
 Additional documentation may be required for executors, trustees or corpora-
 tions or when deemed appropriate by the Transfer Agent.
 
                                                                              63

 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 The Trust may accept telephone redemption instructions from any person iden-
 tifying himself or herself as the owner of an account or the owner's regis-
 tered representative where the owner has not declined in writing to use this
 service. Thus, you risk possible losses if a telephone redemption is not
 authorized by you.
 
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs and NFDS each employ reasonable proce-
 dures specified by the Trust to confirm that such instructions are genuine.
 If reasonable procedures are not employed, the Trust may be liable for any
 loss due to unauthorized or fraudulent transactions. The following general
 policies are currently in effect:
 . All telephone requests are recorded.
 . Proceeds of telephone redemption requests will be sent only to your address
   of record or authorized bank account designated in the Account Application
   (unless you provide written instructions and a signature guarantee, indi-
   cating another address or account) and exchanges of shares normally will be
   made only to an identically registered account.
 . Telephone redemptions will not be accepted during the 30-day period follow-
   ing any change in your address of record.
 . The telephone redemption option does not apply to shares held in a "street
   name" account. "Street name" accounts are accounts maintained and serviced
   by your Authorized Dealer. If your account is held in "street name," you
   should contact your registered representative of record, who may make tele-
   phone redemptions on your behalf.
 . The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
 How Are Redemption Proceeds Paid?
 By Wire: You may arrange for your redemption proceeds to be wired as federal
 funds to the bank account designated in your Account Application. The fol-
 lowing general policies govern wiring redemption proceeds:
 . Redemption proceeds will normally be wired on the next business day in fed-
   eral funds (for a total of one business day delay), but may be paid up to
   three business days following receipt of a properly executed wire transfer
   redemption request. If you are selling shares you recently paid for by
   check, the Fund will pay you when your check has cleared, which may take up
   to 15 days.

                                                               SHAREHOLDER GUIDE
 
  If the Federal Reserve Bank is closed on the day that the redemption pro-
  ceeds would ordinarily be wired, wiring the redemption proceeds may be
  delayed one additional business day.
 . A transaction fee of $7.50 may be charged for payments of redemption pro-
  ceeds by wire. Your bank may also charge wiring fees. You should contact
  your bank directly to learn whether it charges such fees.
 . To change the bank designated on your Account Application you must send
  written instructions (with your signature guaranteed) to the Transfer
  Agent.
 . Neither the Trust, Goldman Sachs nor any Authorized Dealer assumes any
  responsibility for the performance of your bank or any intermediaries in
  the transfer process. If a problem with such performance arises, you should
  deal directly with your bank or any such intermediaries.
By Check: You may elect to receive your redemption proceeds by check.
Redemption proceeds paid by check will normally be mailed to the address of
record within three business days of a properly executed redemption request.
If you are selling shares you recently paid for by check, the Fund will pay
you when your check has cleared, which may take up to 15 days.

What Else Do I Need To Know About Redemptions?
The following generally applies to redemption requests:
 . Shares of each Fund (other than the Global Income Fund) earn dividends
  declared on the day the shares are redeemed.
 . Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 
The Trust reserves the right to:
 . Redeem your shares if your account balance is less than $50 as a result of
  earlier redemptions. The Funds will not redeem your shares on this basis if
  the value of your account falls below the minimum account balance solely as
  a result of market conditions. The Funds will give you 60 days' prior writ-
  ten notice to allow you to purchase sufficient additional shares of the
  Fund in order to avoid such redemption.
 . Redeem your shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 . Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 
                                                                              65

 Can I Reinvest Redemption Proceeds In The Same Or Another Goldman Sachs
 Fund?
 You may redeem shares of a Fund and reinvest a portion or all of the redemp-
 tion proceeds (plus any additional amounts needed to round off purchases to
 the nearest full share) at NAV. To be eligible for this privilege, you must
 hold the shares you want to redeem for at least 30 days and you must rein-
 vest the share proceeds within 90 days after you redeem. You may reinvest as
 follows:
   . Class A or B Shares--Class A Shares of the same Fund or any other Goldman
     Sachs Fund
   . Class C Shares--Class C Shares of the same Fund or any other Goldman
     Sachs Fund
 . You should obtain and read the applicable prospectuses before investing in
   any other Funds.
 . If you pay a CDSC upon redemption of Class A or Class C Shares and then
   reinvest in Class A or Class C Shares as described above, your account will
   be credited with the amount of the CDSC you paid. The reinvested shares
   will, however, continue to be subject to a CDSC. The holding period of the
   shares acquired through reinvestment will include the holding period of the
   redeemed shares for purposes of computing the CDSC payable upon a subse-
   quent redemption. For Class B Shares, you may reinvest the redemption pro-
    ceeds in Class A Shares at NAV but the amount of the CDSC paid upon redemp-
   tion of the Class B Shares will not be credited to your account.
 . The reinvestment privilege may be exercised at any time in connection with
   transactions in which the proceeds are reinvested at NAV in a tax-sheltered
   retirement plan. In other cases, the reinvestment privilege may be exer-
   cised once per year upon receipt of a written redemption request.
 . You may be subject to tax as a result of a redemption. You should consult
   your tax adviser concerning the tax consequences of a redemption and rein-
   vestment.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange shares of a Fund at NAV without the imposition of an ini-
 tial sales charge or CDSC at the time of exchange for shares of the same
 class or an equivalent class of any other Goldman Sachs Fund. The exchange
 privilege may be materially modified or withdrawn at any time upon 60 days'
 written notice to you.

  You should keep in mind the following factors when making or considering an
  exchange:

  .You should obtain and carefully read the prospectus of the Fund you are
   acquiring before making an exchange.

  .Six free exchanges are allowed in each 12 month period.

  .A $12.50 fee may be charged for each subsequent exchange.

  .There is no charge for exchanges made pursuant to the Automatic Exchange
   Program.

  .The exchanged shares may later be exchanged for shares of the same class
   (or an equivalent class) of the original Fund at the next determined NAV
   without the imposition of an initial sales charge or CDSC if the amount
   in the Fund resulting from such exchanges is less than the largest amount
   on which you have previously paid the applicable sales charge.

  .When you exchange shares subject to a CDSC, no CDSC will be charged at
   that time. The exchanged shares will be subject to the CDSC of the shares
   originally held. For purposes of determining the amount of the applicable
   CDSC, the length of time you have owned the shares will be measured from
   the date you acquired the original shares subject to a CDSC and will not
   be affected by a subsequent exchange.
 
                                                                              67

  .Eligible investors may exchange certain classes of shares for another
   class of shares of the same Fund. For further information, call Goldman
   Sachs Funds at 1-800-526-7384.

  .All exchanges which represent an initial investment in a Fund must sat-
   isfy the minimum initial investment requirements of that Fund.

  .Exchanges are available only in states where exchanges may be legally
   made.

  .It may be difficult to make telephone exchanges in times of drastic eco-
   nomic or market conditions.

  .Goldman Sachs and NFDS may use reasonable procedures described under
   "What Do I Need To Know About Telephone Redemption Request?" in an effort
   to prevent unauthorized or fraudulent telephone exchange requests.

  .Telephone exchanges normally will be made only to an identically regis-
   tered account. Shares may be exchanged among accounts with different
   names, addresses and social security or other taxpayer identification
   numbers only if the exchange instructions are in writing and accompanied
   by a signature guarantee.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 SHAREHOLDER SERVICES
 
 
 Can I Arrange To Have Automatic Investments Made On A Regular Basis?
 You may be able to make systematic cash investments through your bank via
 ACH transfer or your checking account via bank draft each month. Forms for
 this option are available from Goldman Sachs, your Authorized Dealer or you
 may check the appropriate box on the Account Application.
 
 Can My Dividends And Distributions From A Fund Be Invested In Other Funds?
 You may elect to cross-reinvest dividends and capital gain distributions
 paid by a Fund in shares of the same class or an equivalent class of any
 other Goldman Sachs Fund.

 .Shares will be purchased at NAV.

 .No initial sales charge or CDSC will be imposed.

 .You may elect cross-reinvestment into an identically registered account or
  an account registered in a different name or with a different address,
  social security number or taxpayer identification number provided that the
  account has

  been properly established, appropriate signatures obtained and the minimum
  initial investment has been satisfied.
 
 Can I Arrange To Have Automatic Exchanges Made On A Regular Basis?
 You may elect to exchange automatically a specified dollar amount of shares
 of a Fund for shares of the same class or an equivalent class of any other
 Goldman Sachs Fund.

 .Shares will be purchased at NAV.

 .No initial sales charge is imposed.

 .Shares subject to a CDSC acquired under this program may be subject to a
  CDSC at the time of redemption from the Fund into which the exchange is
  made depending upon the date and value of your original purchase.

 .Automatic exchanges are made monthly on the 15th day of each month or the
  first business day thereafter.

 .Minimum dollar amount: $50 per month.
 
 What Else Should I Know About Cross-Reinvestments And Automatic Exchanges?
 Cross-reinvestments and automatic exchanges are subject to the following
 conditions:

 .You must hold $5,000 or more in the Fund which is paying the dividend or
  from which the exchange is being made.

 .You must invest an amount in the Fund into which cross-reinvestments or
  automatic exchanges are being made that is equal to that Fund's minimum
  initial investment or continue to cross-reinvest or to make automatic
  exchanges until such minimum initial investment is met.

 .You should obtain and read the prospectus of the Fund into which dividends
  are invested or automatic exchanges are made.
 
 Can I Have Automatic Withdrawals Made On A Regular Basis?
 You may draw on your account systematically via check or ACH transfer in any
 amount of $50 or more.

 .It is normally undesirable to maintain a systematic withdrawal plan at the
  same time that you are purchasing additional Class A, Class B or Class C
  Shares because of the sales charge imposed on your purchases of Class A
  Shares or the imposition of a CDSC on your redemptions of Class A, Class B
  or Class C Shares.

 .You must have a minimum balance of $5,000 in a Fund.

 .Checks are mailed on or about the 25th day of each month.

 .Each systematic withdrawal is a redemption and therefore a taxable transac-
  tion.

 .The CDSC applicable to Class A, Class B or Class C Shares redeemed under
  the systematic withdrawal plan may be waived.
 
                                                                              69

 What Types of Reports Will I Be Sent Regarding My Investment?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-526-7384. You will also be provided with a
 printed confirmation for each transaction in your account and an individual
 quarterly account statement. A year-to-date statement for your account will
 be provided upon request made to Goldman Sachs. If your account is held in
 "street name" you may receive your statement and confirmations on a differ-
 ent schedule. The Funds do not generally provide sub-accounting services.
 
 What Should I Know When I Purchase Shares Through An Authorized Dealer?
 Authorized Dealers and other financial intermediaries may provide varying
 arrangements for their clients to purchase and redeem Fund shares. They may
 charge additional fees not described in this Prospectus to their customers
 for such services.
 
 If shares of a Fund are held in a "street name" account with an Authorized
 Dealer, all recordkeeping, transaction processing and payments of distribu-
 tions relating to your account will be performed by the Authorized Dealer,
 and not by the Fund and its Transfer Agent. Since the Funds will have no
 record of your transactions, you should contact the Authorized Dealer to
 purchase, redeem or exchange shares, to make changes in or give instructions
 concerning the account or to obtain information about your account. The
 transfer of shares in a "street name" account to an account with another
 dealer or to an account directly with the Fund involves special procedures
 and will require you to obtain historical purchase information about the
 shares in the account from the Authorized Dealer.
 
 Authorized Dealers and other financial intermediaries may be authorized to
 accept, on behalf of the Trust, purchase, redemption and exchange orders
 placed by or on behalf of their customers, and if approved by the Trust, to
 designate other intermediaries to accept such orders. In these cases:
 
 .A Fund will be deemed to have received an order that is in proper form when
  the order is accepted by an Authorized Dealer or intermediary on a business
  day, and the order will be priced at the Fund's NAV per share (adjusted for
  any applicable sales charge) next determined after such acceptance.

 .Authorized Dealers and intermediaries are responsible for transmitting
  accepted orders to the Funds within the time period agreed upon by them.

 You should contact your Authorized Dealer or intermediary to learn whether
 it is authorized to accept orders for the Trust.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Authorized Dealers and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Autho-
 rized Dealers depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses. Additional
 compensation based on sales may, but is currently not expected to, exceed
 0.50% (annualized) of the amount invested.
 
 DISTRIBUTION SERVICES AND FEES
 
 
 What Are the Different Distribution and Service Fees Paid by Class A, B and
 C Shares?
 The Trust has adopted distribution and service plans (each a "Plan") under
 which Class A, Class B and Class C Shares bear distribution and service fees
 paid to Authorized Dealers and Goldman Sachs. If the fees received by
 Goldman Sachs pursuant to the Plans exceed its expenses, Goldman Sachs may
 realize a profit from this arrangement. Goldman Sachs pays the distribution
 and service fees on a quarterly basis.
 
 Under the Plans, Goldman Sachs is entitled to a monthly fee from each Fund
 for distribution services equal, on an annual basis, to 0.25%, 0.75% and
 0.75%, respectively, of a Fund's average daily net assets attributed to
 Class A, Class B and Class C Shares.* Because these fees are paid out of the
 Fund's assets on an ongoing basis, over time, these fees will increase the
 cost of your investment and may cost you more than paying other types of
 such charges.
 
 The distribution fees are subject to the requirements of Rule 12b-1 under
 the Act, and may be used (among other things) for:

 .Compensation paid to and expenses incurred by Authorized Dealers, Goldman
  Sachs and their respective officers, employees and sales representatives;

 .Commissions paid to Authorized Dealers;

 .Allocable overhead;

 .Telephone and travel expenses;

 .Interest and other costs associated with the financing of such compensation
  and expenses;
 
                                                                              71
<PAGE>
 
 .Printing of prospectuses for prospective shareholders;

 .Preparation and distribution of sales literature or advertising of any
  type; and

 .All other expenses incurred in connection with activities primarily
  intended to result in the sale of Class A, Class B and Class C Shares.
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.75% distribution fee as an ongoing commission to Authorized Dealers
 after the shares have been held for one year.
 
 * Currently, Goldman Sachs voluntarily limits such fees to 0.60% of the
   average daily net assets attributed to Class B Shares of the Short
   Duration Government and the Short Duration Tax-Free Funds. Goldman Sachs
   may modify or discontinue such waivers in the future at its discretion.
 
 PERSONAL ACCOUNT MAINTENANCE SERVICES AND FEES
 
 
 Under the Plans, Goldman Sachs is also entitled to receive a separate fee
 equal on an annual basis to 0.25% of each Fund's average daily net assets
 attributed to Class A (Global Income Fund only), Class B or Class C Shares.
 This fee is for personal and account maintenance services, and may be used
 to make payments to Goldman Sachs, Authorized Dealers and their officers,
 sales representatives and employees for responding to inquiries of, and fur-
 nishing assistance to, shareholders regarding ownership of their shares or
 their accounts or similar services not otherwise provided on behalf of the
 Funds. If the fees received by Goldman Sachs pursuant to the Plans exceed
 its expenses, Goldman Sachs may realize a profit from this arrangement.
 
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.25% ongoing service fee to Authorized Dealers after the shares have
 been held for one year. In connection with the sale of Class A and B Shares
 of the Short Duration Government and Short Duration Tax-Free Funds, Goldman
 Sachs begins paying the 0.25% ongoing service fee to Authorized Dealers
 after the shares have been held for one year.

Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Except for exempt-interest dividends paid by the Short Duration Tax-Free and
 Municipal Income Funds as described below, Fund distributions are taxable to
 you as ordinary income (unless your investment is in an IRA or other tax-
 advantaged account) to the extent they are attributable to the Fund's net
 investment income, certain net realized foreign exchange gains, and net
 short-term capital gains. They are taxable as long-term capital gain to the
 extent they are attributable to the Fund's excess of net long-term capital
 gains over net short-term capital losses. The tax status of any distribution
 is the same regardless of how long you have been in the Fund and whether you
 reinvest in additional shares or take the distributions as cash. Certain
 distributions paid by a Fund in January of a given year may be taxable to
 shareholders as if received the prior December 31. The tax status and
 amounts of distribution for each calendar year will be detailed in your
 annual tax statement from the Fund.
 
 At any time, a portion of a Fund's NAV per share may be represented by
 undistributed income or realized or unrealized appreciation of the Fund's
 portfolio securities. Therefore, subsequent distributions on a Fund's shares
 may be taxable to you, even if the NAV of your shares is, as a result,
 reduced below the cost of those shares and the distributions represent a
 return of your purchase price.
 
 The Core Fixed Income, Global Income and High Yield Funds may be subject to
 foreign withholding or other foreign taxes on income or gain from certain
 foreign securities. In general, the Funds may deduct these taxes in comput-
 ing their taxable income. As an alternative, the Global Income Fund (but not
 the other Funds) may make an election to treat a proportionate amount of
 such taxes as constituting a distribution to you, which would allow you
 either to (1) credit such proportionate amount of taxes against your U.S.
 federal income tax liability or (2) take such amount as an itemized deduc-
 tion.
 
 The Short Duration Tax-Free and Municipal Income Funds expect to distribute
 "exempt-interest dividends." These dividends will be exempt income for fed-
 eral income tax purposes. However, distributions, if any, derived from net
 long-term capital gains of the Short Duration Tax-Free and Municipal Income
 Funds will generally be taxable to you as long-term capital gains. Distribu-
 tions, if any, derived from taxable interest income, net short-term capital
 gains
 
                                                                              73
<PAGE>
 
 
 and certain net realized foreign exchange gains will be taxable to you as
 ordinary income.
 
 Interest on indebtedness incurred by you to purchase or carry shares of the
 Short Duration Tax-Free and Municipal Income Funds generally will not be
 deductible for federal income tax purposes.
 
 You should note that exempt-interest dividends paid by the Short Duration
 Tax-Free and Municipal Income Funds may be an item of tax preference for
 purposes of determining your federal alternative minimum tax liability.
 Exempt-interest dividends will also be considered along with other adjusted
 gross income in determining whether any Social Security or railroad retire-
 ment payments received by you are subject to federal income taxes.
 
 If you receive an exempt-interest dividend on shares that are held by you
 for six months or less, any loss on the sale or exchange of the shares will
 be disallowed to the extent of such dividend amount.
 
 There are certain tax requirements that all Funds must follow in order to
 avoid federal taxation. In their efforts to adhere to these requirements,
 the Funds may have to limit their investment activity in some types of
 instruments.
 
 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Fund shares may generate a tax liability (unless
 your investment is in an IRA or other tax-advantaged account). Depending
 upon the purchase or sale price of the shares you sell or exchange, you may
 have a gain or a loss on the transaction.
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Fund, based on the
 difference between your tax basis in the shares and the amount you receive
 for them. (To aid in computing your tax basis, you generally should retain
 your account statements for the periods that you hold shares.) Any loss rec-
 ognized on shares held for six months or less will be treated as a long-term
 capital loss to the extent of any capital gain dividends that were received
 with respect to the shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from any Fund (including the Short Dura-
 tion Tax-Free and Municipal Income Funds) or on the value of the shares held
 by you. More tax information is provided in the Additional Statement. You
 should also consult your own tax adviser for information regarding all tax
 consequences applicable to your investments in the Funds.

Appendix A
Additional Information on Portfolio Risks, Securities and Techniques
 A. General Portfolio Risks
 
 
 The Funds will be subject to the risks associated with fixed-income securi-
 ties. These risks include interest rate risk, credit risk and call/extension
 risk. In general, interest rate risk involves the risk that when interest
 rates decline, the market value of fixed-income securities tends to
 increase. Conversely, when interest rates increase, the market value of
 fixed-income securities tends to decline. Credit risk involves the risk that
 the issuer could default on its obligations, and a Fund will not recover its
 investment. Call risk and extension risk are normally present in adjustable
 rate mortgage loans ("ARMs"), Mortgage-Backed Securities and asset-backed
 securities. For example, homeowners have the option to prepay their mort-
 gages. Therefore, the duration of a security backed by home mortgages can
 either shorten (call risk) or lengthen (extension risk). In general, if
 interest rates on new mortgage loans fall sufficiently below the interest
 rates on existing outstanding mortgage loans, the rate of prepayment would
 be expected to increase. Conversely, if mortgage loan interest rates rise
 above the interest rates on existing outstanding mortgage loans, the rate of
 prepayment would be expected to decrease. In either case, a change in the
 prepayment rate can result in losses to investors.
 
 The Investment Adviser will not consider the portfolio turnover rate a lim-
 iting factor in making investment decisions for a Fund. A high rate of port-
 folio turnover (100% or more) involves correspondingly greater expenses
 which must be borne by a Fund and its shareholders. The portfolio turnover
 rate is calculated by dividing the lesser of the dollar amount of sales or
 purchases of portfolio securities by the average monthly value of a Fund's
 portfolio securities, excluding securities having a maturity at the date of
 purchase of one year or less. See "Financial Highlights" in Appendix B for a
 statement of the Funds' historical portfolio turnover rates.
 
 The following sections provide further information on certain types of secu-
 rities and investment techniques that may be used by the Funds, including
 their associated risks. Additional information is provided in the Additional
 Statement, which is available upon request. Among other things, the Addi-
 tional Statement describes certain fundamental investment restrictions that
 cannot be changed without shareholder approval. You should note, however,
 that all policies not specifically designated as fundamental are non-funda-
 mental and may
 
                                                                              75
<PAGE>
 
 
 be changed without shareholder approval. If there is a change in a Fund's
 investment objective, you should consider whether that Fund remains an
 appropriate investment in light of your then current financial positions and
 needs.
 
 B. Other Portfolio Risks
 
 
 Credit Risks. Debt securities purchased by the Funds may include securities
 (including zero coupon bonds) issued by the U.S. government (and its agen-
 cies, instrumentalities and sponsored enterprises), foreign governments,
 domestic and foreign corporations, banks and other issuers. Some of these
 fixed-income securities are described in the next section below. Further
 information is provided in the Additional Statement.
 
 Debt securities rated BBB or higher by Standard & Poor's or Baa or higher by
 Moody's are considered "investment grade." Securities rated BBB or Baa are
 considered medium-grade obligations with speculative characteristics, and
 adverse economic conditions or changing circumstances may weaken their
 issuers' capacity to pay interest and repay principal. A security will be
 deemed to have met a rating requirement if it receives the minimum required
 rating from at least one such rating organization even though it has been
 rated below the minimum rating by one or more other rating organizations, or
 if unrated by such rating organizations, is determined by the Investment
 Adviser to be of comparable credit quality.
 
 Certain Funds may invest in fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) which are commonly referred to as "junk
 bonds." Junk bonds are considered predominantly speculative and may be ques-
 tionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in a Fund's portfolio is downgraded by a rat-
 ing organization, the market price and liquidity of such security may be
 adversely affected.
 
 Risks of Derivative Investments. A Fund's transactions, if any, in options,
 futures, options on futures, swaps, interest rate caps, floors and collars,
 structured securities, inverse floating-rate securities, stripped mortgage-
 backed securities and currency transactions involve additional risk of loss.
 Loss can result from a lack of correlation between changes in the value of
 derivative instruments and the portfolio assets (if any) being hedged, the
 potential illiquidity of the markets for derivative instruments, or the
 risks arising from margin requirements and related lever-
 
76
<PAGE>
 
                                                                      APPENDIX A
 
 age factors associated with such transactions. The use of these management
 techniques also involves the risk of loss if the Investment Adviser is
 incorrect in its expectation of fluctuations in securities prices, interest
 rates or currency prices. Each Fund may also invest in derivative invest-
 ments for non-hedging purposes (that is, to seek to increase total return),
 which is considered a speculative practice and presents even greater risk of
 loss.
 
 Derivative Mortgage-Backed Securities (such as principal-only ("POs"),
 interest-only ("IOs") or inverse floating rate securities) are particularly
 exposed to call and extension risks. Small changes in mortgage prepayments
 can significantly impact the cash flow and the market value of these securi-
 ties. In general, the risk of faster than anticipated prepayments adversely
 affects IOs, super floaters and premium priced Mortgage-Backed Securities.
 The risk of slower than anticipated prepayments generally adversely affects
 POs, floating-rate securities subject to interest rate caps, support
 tranches and discount priced Mortgage-Backed Securities. In addition, par-
 ticular derivative securities may be leveraged such that their exposure
 (i.e., price sensitivity) to interest rate and/or prepayment risk is
 magnified.
 
 Some floating-rate derivative debt securities can present more complex types
 of derivative and interest rate risks. For example, range floaters are sub-
 ject to the risk that the coupon will be reduced below market rates if a
 designated interest rate floats outside of a specified interest rate band or
 collar. Dual index or yield curve floaters are subject to lower prices in
 the event of an unfavorable change in the spread between two designated
 interest rates.
 
 Risks of Foreign Investments. Foreign investments involve special risks that
 are not typically associated with U.S. dollar denominated or quoted securi-
 ties of U.S. issuers. Foreign investments may be affected by changes in cur-
 rency rates, changes in foreign or U.S. laws or restrictions applicable to
 such investments and changes in exchange control regulations (e.g., currency
 blockage). A decline in the exchange rate of the currency (i.e., weakening
 of the currency against the U.S. dollar) in which a portfolio security is
 quoted or denominated relative to the U.S. dollar would reduce the value of
 the portfolio security. In addition, if the currency in which a Fund
 receives dividends, interest or other payments declines in value against the
 U.S. dollar before such income is distributed as dividends to shareholders
 or converted to U.S. dollars, the Fund may have to sell portfolio securities
 to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts
 
                                                                              77
<PAGE>
 
 
 after January 1, 1999 that refer to existing currencies rather than the
 euro; the establishment and maintenance of exchange rates for currencies
 being converted into the euro; the fluctuation of the euro relative to non-
 euro currencies during the transition period from January 1, 1999 to Decem-
 ber 31, 2001 and beyond; whether the interest rate, tax and labor regimes of
 European countries participating in the euro will converge over time; and
 whether the conversion of the currencies of other countries that now are or
 may in the future become members of the European Union ("EU") may have an
 impact on the euro. These or other factors, including political and economic
 risks, could cause market disruptions, and could adversely affect the value
 of securities held by the Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than a U.S. issuer. In addition, there is generally less government
 regulation of foreign markets, companies and securities dealers than in the
 United States. Foreign securities markets may have substantially less volume
 than U.S. securities markets and securities of many foreign issuers are less
 liquid and more volatile than securities of comparable domestic issuers.
 Furthermore, with respect to certain foreign countries, there is a possibil-
 ity of nationalization, expropriation or confiscatory taxation, imposition
 of withholding or other taxes on dividend or interest payments (or, in some
 cases, capital gains), limitations on the removal of funds or other assets
 of the Funds, and political or social instability or diplomatic developments
 which could affect investments in those countries.
 
 Concentration of a Fund's assets in one or a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations by certain Funds involves risks not
 present in debt obligations of corporate issuers. The issuer of the debt or
 the governmental authorities that control the repayment of the debt may be
 unable or unwilling to repay principal or interest when due in accordance
 with the terms of such
 
78
<PAGE>
 
                                                                      APPENDIX A
 
 debt, and a Fund may have limited recourse to compel payment in the event of
 a default. Periods of economic uncertainty may result in volatility of mar-
 ket prices of sovereign debt, and in turn a Fund's NAV, to a greater extent
 than the volatility inherent in debt obligations of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Risks of Emerging Countries. Certain Funds may invest in securities of
 issuers located in emerging countries. The risks of foreign investment are
 heightened when the issuer is located in an emerging country. Emerging coun-
 tries are generally located in the Asia-Pacific region, Eastern Europe,
 Latin and South America and Africa. A Fund's purchase and sale of portfolio
 securities in certain emerging countries may be constrained by limitations
 as to daily changes in the prices of listed securities, periodic trading or
 settlement volume and/or limitations on aggregate holdings of foreign
 investors. Such limitations may be computed based on the aggregate trading
 volume by or holdings of a Fund, the Investment Adviser, its affiliates and
 their respective clients and other service providers. A Fund may not be able
 to sell securities in circumstances where price, trading or settlement vol-
 ume limitations have been reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, such as Taiwan, it is
 anticipated that a Fund may invest in such countries only through other
 investment funds in such countries.
 
                                                                              79
<PAGE>
 
 
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and ethnic, religious and racial disaffec-
 tion, among other factors, have also led to social unrest, violence and/or
 labor unrest in some emerging countries. Unanticipated political or social
 developments may result in sudden and significant investment losses. Invest-
 ing in emerging countries involves greater risk of loss due to expropria-
 tion, nationalization, confiscation of assets and property or the imposition
 of restrictions on foreign investments and on repatriation of capital
 invested.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of those emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 A Fund's investment in emerging countries may also be subject to withholding
 or other taxes, which may be significant and may reduce the return from an
 investment in such country to the Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve a Fund's
 delivery of securities before receipt of payment for their sale. In addi-
 tion, significant delays are common in certain markets in registering the
 transfer of securities. Settlement or registration problems may make it more
 difficult for a Fund to value its portfolio securities and could cause the
 Fund to miss attractive investment opportunities, to have a portion of its
 assets uninvested or to incur losses due to the failure of a counterparty to
 pay for securities the Fund has delivered or the Fund's inability to com-
 plete its contractual obligations. The creditworthiness of the local securi-
 ties firms used by the Funds in emerging countries may not be as sound as
 the creditworthiness of firms used in more developed countries. As a result,
 the Fund may be subject to a greater risk of loss if a securities firm
 defaults in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make a Fund's investments in such countries less liquid and more
 volatile than invest-
 
80

                                                                      APPENDIX A
 
 ments in countries with more developed securities markets (such as the
 United States, Japan and most Western European countries). A Fund's invest-
 ments in emerging countries are subject to the risk that the liquidity of
 particular investment, or investments generally, in such countries will
 shrink or disappear suddenly and without warning as a result of adverse eco-
 nomic, market or political conditions or adverse investor perceptions,
 whether or not accurate. Because of the lack of sufficient market liquidity,
 a Fund may incur losses because it will be required to effect sales at a
 disadvantageous time and then only at a substantial drop in price. Invest-
 ments in emerging countries may be more difficult to price precisely because
 of these characteristics and lower trading volumes.
 
 A Fund's use of foreign currency management techniques in emerging countries
 may be limited. Due to the limited market for these instruments in emerging
 countries, the Investment Adviser does not currently anticipate that a sig-
 nificant portion of the Funds' currency exposure in emerging countries, if
 any, will be covered by such instruments.
 
 Risks of Illiquid Securities. Each Fund may invest up to 15% of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
 
 .Both domestic and foreign securities that are not readily marketable

 .Certain municipal leases and participation interests

 .Certain stripped Mortgage-Backed Securities

 .Repurchase agreements and time deposits with a notice or demand period of
  more than seven days

 .Certain over-the-counter options

 .Certain restricted securities, unless it is determined, based upon a review
  of the trading markets for a specific restricted security, that such
  restricted security is eligible for resale pursuant to Rule 144A under the
  Securities Act of 1933 ("144A Securities") and, therefore, is liquid
 
 Investing in 144A Securities may decrease the liquidity of a Fund's portfo-
 lio to the extent that qualified institutional buyers become for a time
 uninterested in purchasing these restricted securities. The purchase price
 and subsequent valuation of restricted and illiquid securities normally
 reflect a discount, which may be significant, from the market price of com-
 parable securities for which a liquid market exists.
 
 Temporary Investment Risks. Each Fund may, for temporary defensive purposes,
 invest a certain percentage of its total assets in:
 
 .U.S. Government Securities

 .Repurchase agreements collateralized by U.S. Government Securities
 
                                                                              81
<PAGE>
 
 
 Certain Funds may invest more than 20% of their respective net assets in
 taxable investments and in investment grade securities for temporary defen-
 sive purposes.
 
 C. Portfolio Securities and Techniques
 
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the Funds, including their associ-
 ated risks. Further information is provided in the Additional Statement,
 which is available upon request.
 
 U.S. Government Securities and Related Custodial Receipts. U.S. Government
 Securities include U.S. Treasury obligations and obligations issued or guar-
 anteed by U.S. government agencies, instrumentalities or sponsored enter-
 prises. U.S. Government Securities may be supported by (a) the full faith
 and credit of the U.S. Treasury (such as the Government National Mortgage
 Association ("Ginnie Mae")); (b) the right of the issuer to borrow from the
 U.S. Treasury (such as securities of the Student Loan Marketing Associa-
 tion); (c) the discretionary authority of the U.S. government to purchase
 certain obligations of the issuer (such as the Federal National Mortgage
 Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation
 ("Freddie Mac")); or (d) only the credit of the issuer. U.S. Government
 Securities also include Treasury receipts, zero coupon bonds and other
 stripped U.S. Government Securities, where the interest and principal compo-
 nents of stripped U.S. Government Securities are traded independently.
 
 Interests in U.S. Government Securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S. govern-
 ment.
 
 Mortgage-Backed Securities. Mortgage-Backed Securities represent direct or
 indirect participations in, or are collateralized by and payable from, mort-
 gage loans secured by real property. Mortgage-Backed Securities can be
 backed by either fixed rate mortgage loans or adjustable rate mortgage
 loans, and may be issued by either a governmental or non-governmental enti-
 ty. Privately issued Mortgage-Backed Securities are normally structured with
 one or more types of "credit enhancement." However, these Mortgage-Backed
 Securities typically do not have the same credit standing as U.S. government
 guaranteed Mortgage-Backed Securities.

 Mortgage-Backed Securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs") and Real Estate Mortgage
 Investment Conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an investor with a specified interest in the cash flow from a
 pool of underlying mortgages or of other Mortgage-Backed Securities. CMOs
 are issued in multiple classes. In most cases, payments of principal are
 applied to the CMO classes in the order of their respective stated maturi-
 ties, so that no principal payments will be made on a CMO class until all
 other classes having an earlier stated maturity date are paid in full. A
 REMIC is a CMO that qualifies for special tax treatment under the Code and
 invests in certain mortgages principally secured by interests in real prop-
 erty and other permitted investments.
 
 Mortgaged-Backed Securities also include stripped Mortgage-Backed Securities
 ("SMBS"), which are derivative multiple class Mortgage-Backed Securities.
 SMBS are usually structured with two different classes: one that receives
 100% of the interest payments and the other that receives 100% of the prin-
 cipal payments from a pool of mortgage loans. The market value of SMBS con-
 sisting entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage loans are generally higher than pre-
 vailing market yields on other Mortgage-Backed Securities because their cash
 flow patterns are more volatile and there is a greater risk that the initial
 investment will not be fully recouped.
 
 Asset-Backed Securities. Asset-backed securities are securities whose prin-
 cipal and interest payments are collateralized by pools of assets such as
 auto loans, credit card receivables, leases, installment contracts and per-
 sonal property. Asset-backed securities are often subject to more rapid
 repayment than their stated maturity date would indicate as a result of the
 pass-through of prepayments of principal on the underlying loans. During
 periods of declining interest rates, prepayment of loans underlying asset-
 backed securities can be expected to accelerate. Accordingly, a Fund's abil-
 ity to maintain positions in such securities will be affected by reductions
 in the principal amount of such securities resulting from prepayments, and
 its ability to reinvest the returns of principal at comparable yields is
 subject to generally prevailing interest rates at that time. Asset-backed
 securities present credit risks that are not presented by Mortgage-Backed
 Securities. This is because asset-backed securities generally do not have
 the benefit of a security interest in collateral that is comparable to mort-
 gage assets. There is the possibility that, in some cases, recoveries on
 repossessed collateral may not be available to support payments on these
 securities. In the event of a default, a Fund may suffer a loss if it cannot
 sell collateral quickly and receive the amount it is owed.

 Municipal Securities. Municipal Securities include bonds, notes, commercial
 paper and other instruments (including participation interests in such secu-
 rities) issued by or on behalf of the states, territories and possessions of
 the United States (including the District of Columbia) and their political
 subdivisions, agencies or instrumentalities, the interest on which, in the
 opinion of bond counsel for the issuers or counsel selected by the Invest-
 ment Adviser, is exempt from regular federal income tax (i.e., excluded from
 gross income for federal income tax purposes but not necessarily exempt from
 federal alternative minimum tax or from state or local taxes). Because of
 their tax-exempt status, the yields and market values of Municipal Securi-
 ties may be more adversely impacted by changes in tax rates and policies
 than taxable fixed-income securities.
 
 Municipal Securities are often issued to obtain funds for various public
 purposes, including the construction of a wide range of public facilities
 such as bridges, highways, housing, hospitals, mass transportation, schools,
 streets and water and sewer works. Municipal Securities include private
 activity bonds, municipal leases, certificates of participation, pre-
 refunded municipal securities and auction rate securities.
 
 The obligations of the issuer to pay the principal of and interest on a
 Municipal Security are subject to the provisions of bankruptcy, insolvency
 and other laws affecting the rights and remedies of creditors, such as the
 Federal Bankruptcy Act, and laws, if any, that may be enacted by Congress or
 state legislatures extending the time for payment of principal or interest
 or imposing other constraints upon the enforcement of such obligations.
 There is also the possibility that, as a result of litigation or other con-
 ditions, the power or ability of the issuer to pay when due the principal of
 or interest on a Municipal Security may be materially affected. Municipal
 lease obligations and certificates of participation are subject to the added
 risk that the governmental lessee will fail to appropriate funds to enable
 it to meet its payment obligations under the lease.
 
 Municipal Securities may be in the form of a tender option bond, which is a
 Municipal Security (generally held pursuant to a custodial arrangement) hav-
 ing a relatively long maturity and bearing interest at a fixed rate substan-
 tially higher than prevailing short-term, tax-exempt rates. The bond is typ-
 ically issued with the agreement of a bank, broker-dealer or other financial
 institution, which grants the security holders the option, at periodic
 intervals, to tender their securities to the institution and receive the
 face value thereof. After payment of a fee to the financial institution that
 provides this option, the security holder effectively holds a demand obliga-
 tion that bears interest at the prevailing short-term, tax-exempt rate. The
 tender option will be taken into account in determining the maturity of the
 tender option bonds and a Fund's average portfolio maturity. There is risk
 that a

                                                                      APPENDIX A
 
 Fund will not be considered the owner of a tender option bond for federal
 income tax purposes, and thus will not be entitled to treat such interest as
 exempt from federal income tax. Certain tender option bonds may be illiquid.
 
 Corporate Debt Obligations; Trust Preferred Securities; Convertible Securi-
 ties. Corporate debt obligations include bonds, notes, debentures and other
 obligations of corporations to pay interest and repay principal, and include
 securities issued by banks and other financial institutions. A trust pre-
 ferred or capital security is a long dated bond (for example, 30 years) with
 preferred features. The preferred features are that payment of interest can
 be deferred for a specified period without initiating a default event. The
 securities are generally senior in claim to standard preferred stock but
 junior to other bondholders.
 
 Convertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than non-convertible securities of similar qual-
 ity. Convertible securities in which a Fund invests are subject to the same
 rating criteria as its other investments in fixed-income securities. Con-
 vertible securities have both equity and fixed-income risk characteristics.
 Like all fixed-income securities, the value of convertible securities is
 susceptible to the risk of market losses attributable to changes in interest
 rates. Generally, the market value of convertible securities tends to
 decline as interest rates increase and, conversely, to increase as interest
 rates decline. However, when the market price of the common stock underlying
 a convertible security exceeds the conversion price of the convertible secu-
 rity, the convertible security tends to reflect the market price of the
 underlying common stock. As the market price of the underlying common stock
 declines, the convertible security, like a fixed-income security, tends to
 trade increasingly on a yield basis, and thus may not decline in price to
 the same extent as the underlying common stock.
 
 Foreign Currency Transactions. A Fund may, to the extent consistent with its
 investment policies, purchase or sell foreign currencies on a cash basis or
 through forward contracts. A forward contract involves an obligation to pur-
 chase or sell a specific currency at a future date at a price set at the
 time of the contract. A Fund may engage in foreign currency transactions for
 hedging purposes and to seek to protect against anticipated changes in
 future foreign currency exchange rates. In addition, a Fund also may enter
 into such transactions to seek to increase total return, which is considered
 a speculative practice.
 
 Some Funds may also engage in cross-hedging by using forward contracts in a
 currency different from that in which the hedged security is denominated or
 quoted if the Investment Adviser determines that there is a pattern of cor-
 relation between the two currencies. A Fund may hold foreign currency
 received in con-
 
                                                                              85
<PAGE>
 
 
 nection with investments in foreign securities when, in the judgment of the
 Investment Adviser, it would be beneficial to convert such currency into
 U.S. dollars at a later date.
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, a Fund's NAV to fluctuate (when the
 Fund's NAV fluctuates, the value of your shares may go up or down). Currency
 exchange rates also can be affected unpredictably by the intervention of
 U.S. or foreign governments or central banks, or the failure to intervene,
 or by currency controls or political developments in the United States or
 abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are not guaranteed by an exchange or clear-
 inghouse, a default on a contract would deprive a Fund of unrealized prof-
 its, transaction costs or the benefits of a currency hedge or could force
 the Fund to cover its purchase or sale commitments, if any, at the current
 market price.
 
 Structured Securities and Inverse Floaters. Structured securities are secu-
 rities whose value is determined by reference to changes in the value of
 specific currencies, interest rates, commodities, indices or other financial
 indicators (the "Reference") or the relative change in two or more Refer-
 ences. The interest rate or the principal amount payable upon maturity or
 redemption may be increased or decreased depending upon changes in the
 applicable Reference. Structured securities may be positively or negatively
 indexed, so that appreciation of the Reference may produce an increase or
 decrease in the interest rate or value of the security at maturity. In addi-
 tion, changes in the interest rates or the value of the security at maturity
 may be a multiple of changes in the value of the Reference. Consequently,
 structured securities may present a greater degree of market risk than other
 types of fixed-income securities, and may be more volatile, less liquid and
 more difficult to price accurately than less complex securities.
 
 Structured securities include, but are not limited to, inverse floating rate
 debt securities ("inverse floaters"). The interest rate on inverse floaters
 resets in the opposite direction from the market rate of interest to which
 the inverse floater is indexed. An inverse floater may be considered to be
 leveraged to the extent that its interest rate varies by a magnitude that
 exceeds the magnitude of the change in the index rate of interest. The
 higher the degree of leverage of an inverse floater, the greater the vola-
 tility of its market value.

 Zero Coupon, Deferred Interest, Pay-In-Kind and Capital Appreciation Bonds.
 Zero coupon, deferred interest, pay-in-kind and capital appreciation bonds
 are issued at a discount from their face value because interest payments are
 typically postponed until maturity. Pay-in-kind securities are securities
 that have interest payable by the delivery of additional securities. The
 market prices of these securities generally are more volatile than the mar-
 ket prices of interest-bearing securities and are likely to respond to a
 greater degree to changes in interest rates than interest-bearing securities
 having similar maturities and credit quality.
 
 Mortgage Dollar Rolls. A mortgage dollar roll involves the sale by a Fund of
 securities for delivery in the current month. The Fund simultaneously con-
 tracts with the same counterparty to repurchase substantially similar (same
 type, coupon and maturity) but not identical securities on a specified
 future date. During the roll period, the Fund loses the right to receive
 principal and interest paid on the securities sold. However, the Fund bene-
 fits to the extent of any difference between (a) the price received for the
 securities sold and (b) the lower forward price for the future purchase
 and/or fee income plus the interest earned on the cash proceeds of the secu-
 rities sold. Unless the benefits of a mortgage dollar roll exceed the
 income, capital appreciation and gain or loss due to mortgage prepayments
 that would have been realized on the securities sold as part of the roll,
 the use of this technique will diminish the Fund's performance.
 
 Successful use of mortgage dollar rolls depends upon the Investment Advis-
 er's ability to predict correctly interest rates and mortgage prepayments.
 If the Investment Adviser is incorrect in its prediction, a Fund may experi-
 ence a loss. For financial reporting and tax purposes, the Funds treat mort-
 gage dollar rolls as two separate transactions: one involving the purchase
 of a security and a separate transaction involving a sale. The Funds do not
 currently intend to enter into mortgage dollar rolls that are accounted for
 as a financing and do not treat them as borrowings.
 
 Options on Securities, Securities Indices and Foreign Currencies. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Fund may write
 (sell) covered call and put options and purchase put and call options on any
 securities in which it may invest or on any securities index comprised of
 securities in which it may invest. A Fund that invests in foreign securities
 may also purchase and sell (write) put and call options on foreign curren-
 cies.
 
 
                                                                              87
<PAGE>
 
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of the Investment Adviser to manage future price fluctu-
 ations and the degree of correlation between the options and securities (or
 currency) markets. If the Investment Adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in a Fund's investment portfolio, the Fund may incur losses that
 it would not otherwise incur. The use of options can also increase a Fund's
 transaction costs. Options written or purchased by the Funds may be traded
 on either U.S. or foreign exchanges or over-the-counter. Foreign and over-
 the-counter options will present greater possibility of loss because of
 their greater liquidity and credit risks.
 
 Yield Curve Options. Each Fund may enter into options on the yield "spread"
 or differential between two securities. Such transactions are referred to as
 "yield curve" options. In contrast to other types of options, a yield curve
 option is based on the difference between the yields of designated securi-
 ties, rather than the prices of the individual securities, and is settled
 through cash payments. Accordingly, a yield curve option is profitable to
 the holder if this differential widens (in the case of a call) or narrows
 (in the case of a put), regardless of whether the yields of the underlying
 securities increase or decrease.
 
 The trading of yield curve options is subject to all of the risks associated
 with the trading of other types of options. In addition, such options pres-
 ent a risk of loss even if the yield of one of the underlying securities
 remains constant, or if the spread moves in a direction or to an extent
 which was not anticipated.
 
 Futures Contracts and Options on Futures Contracts. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 Government Securities), foreign currencies, securities indices and other
 financial instruments and indices. The Funds may engage in futures transac-
 tions on both U.S. and foreign exchanges.
 
 Each Fund may purchase and sell futures contracts, and purchase and write
 call and put options on futures contracts, in order to seek to increase
 total return or to hedge against changes in interest rates, securities
 prices or, to the extent a Fund invests in foreign securities, currency
 exchange rates, or to otherwise manage their

                                                                      APPENDIX A
 
 term structures, sector selection and durations in accordance with their
 investment objectives and policies. Each Fund may also enter into closing
 purchase and sale transactions with respect to such contracts and options. A
 Fund will engage in futures and related options transactions for bona fide
 hedging purposes as defined in regulations of the Commodity Futures Trading
 Commission or to seek to increase total return to the extent permitted by
 such regulations. A Fund may not purchase or sell futures contracts or pur-
 chase or sell related options to seek to increase total return, except for
 closing purchase or sale transactions, if immediately thereafter the sum of
 the amount of initial margin deposits and premiums paid on the Fund's out-
 standing positions in futures and related options entered into for the pur-
 pose of seeking to increase total return would exceed 5% of the market value
 of the Fund's net assets.
 
 Futures contracts and related options present the following risks:

 .While a Fund may benefit from the use of futures and options on futures,
  unanticipated changes in interest rates, securities prices or currency
  exchange rates may result in poorer overall performance than if the Fund
  had not entered into any futures contracts or options transactions.

 .Because perfect correlation between a futures position and portfolio posi-
  tion that is intended to be protected is impossible to achieve, the desired
  protection may not be obtained and a Fund may be exposed to additional risk
  of loss.

 .The loss incurred by a Fund in entering into futures contracts and in writ-
  ing call options on futures is potentially unlimited and may exceed the
  amount of the premium received.

 .Futures markets are highly volatile and the use of futures may increase the
  volatility of a Fund's NAV.

 .As a result of the low margin deposits normally required in futures trad-
  ing, a relatively small price movement in a futures contract may result in
  substantial losses to a Fund.

 .Futures contracts and options on futures may be illiquid, and exchanges may
  limit fluctuations in futures contract prices during a single day.

 .Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to the Fund at the time of entering into the
 transaction. A forward commitment involves entering into a contract to pur-
 chase or sell securities for a fixed price at a future date beyond the cus-
 tomary settlement period.
 
 
                                                                              89
<PAGE>
 
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although a Fund will generally
 purchase securities on a when-issued or forward commitment basis with the
 intention of acquiring securities for its portfolio, a Fund may dispose of
 when-issued securities or forward commitments prior to settlement if the
 Investment Adviser deems it appropriate.
 
 Lending of Portfolio Securities. Securities lending involves the lending of
 securities owned by a Fund to financial institutions such as certain broker-
 dealers. The borrowers are required to secure their loans continuously with
 cash, cash equivalents, U.S. Government Securities or letters of credit in
 an amount at least equal to the market value of the securities loaned. Cash
 collateral may be invested in cash equivalents. If the Investment Adviser
 determines to make securities loans, the value of the securities loaned may
 not exceed 33 1/3% of the value of the total assets of a Fund (including the
 loan collateral).
 
 A Fund may lend its securities to increase its income. A Fund may, however,
 experience delay in the recovery of its securities if the institution with
 which it has engaged in a portfolio loan transaction breaches its agreement
 with the Fund.
 
 Repurchase Agreements. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Fund may enter into repurchase agreements
 with dealers in U.S. Government Securities and member banks of the Federal
 Reserve System which furnish collateral at least equal in value or market
 price to the amount of their repurchase obligation. Some Funds may also
 enter into repurchase agreements involving certain foreign government secu-
 rities.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund are less than the repurchase price and the
 Fund's cost associated with delay and enforcement of the repurchase agree-
 ment. In addition, in the event of bankruptcy of the seller, a Fund could
 suffer additional losses if a court determines that the Fund's interest in
 the collateral is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to a Fund's
 shareholders. In addition, certain Funds, together with other registered
 investment companies having advisory agreements with the Investment Adviser
 or any of its affiliates,
 
90
<PAGE>
 
                                                                      APPENDIX A
 
 may transfer uninvested cash balances into a single joint account, the daily
 aggregate balance of which will be invested in one or more repurchase agree-
 ments.
 
 Borrowings and Reverse Repurchase Agreements. The Funds can borrow money
 from banks and enter into reverse repurchase agreements with banks and other
 financial institutions in amounts not exceeding one-third of its total
 assets. Reverse repurchase agreements involve the sale of securities held by
 a Fund subject to the Fund's agreement to repurchase them at a mutually
 agreed upon date and price (including interest). These transactions may be
 entered into as a temporary measure for emergency purposes or to meet
 redemption requests. Reverse repurchase agreements may also be entered into
 when the Investment Adviser expects that the interest income to be earned
 from the investment of the transaction proceeds will be greater than the
 related interest expense. Borrowings and reverse repurchase agreements
 involve leveraging. If the securities held by a Fund decline in value while
 these transactions are outstanding, the NAV of the Fund's outstanding shares
 will decline in value by proportionately more than the decline in value of
 the securities. In addition, reverse repurchase agreements involve the risk
 that the interest income earned by a Fund (from the investment of the pro-
 ceeds) will be less than the interest expense of the transaction, that the
 market value of the securities sold by a Fund will decline below the price
 the Fund is obligated to pay to repurchase the securities, and that the
 securities may not be returned to the Fund.
 
 Interest Rate Swaps, Mortgage Swaps, Credit Swaps, Currency Swaps and Inter-
 est Rate Caps, Floors and Collars. Interest rate swaps involve the exchange
 by a Fund with another party of their respective commitments to pay or
 receive interest, such as an exchange of fixed-rate payments for floating
 rate payments. Mortgage swaps are similar to interest rate swaps in that
 they represent commitments to pay and receive interest. The notional princi-
 pal amount, however, is tied to a reference pool or pools of mortgages.
 Credit swaps involve the receipt of floating or fixed rate payments in
 exchange for assuming potential credit losses of an underlying security.
 Credit swaps give one party to a transaction the right to dispose of or
 acquire an asset (or group of assets), or the right to receive or make a
 payment from the other party, upon the occurrence of specified credit
 events. Currency swaps involve the exchange of the parties' respective
 rights to make or receive payments in specified currencies. The purchase of
 an interest rate cap entitles the purchaser, to the extent that a specified
 index exceeds a predetermined interest rate, to receive payment of interest
 on a notional principal amount from the party selling such interest rate
 cap. The purchase of an interest rate floor entitles the purchaser, to the
 extent that a specified index falls below a predetermined interest rate, to
 receive payments of interest on a notional principal amount from the party
 
                                                                              91
<PAGE>
 
 
 selling the interest rate floor. An interest rate collar is the combination
 of a cap and a floor that preserves a certain return within a predetermined
 range of interest rates.
 
 Each Fund may enter into swap transactions for hedging purposes or to seek
 to increase total return. The use of interest rate, mortgage, credit and
 currency swaps, as well as interest rate caps, floors and collars, is a
 highly specialized activity which involves investment techniques and risks
 different from those associated with ordinary portfolio securities transac-
 tions. If the Investment Adviser is incorrect in its forecasts of market
 value, interest rates and currency exchange rates, the investment perfor-
 mance of a Fund would be less favorable than it would have been if these
 investment techniques were not used.
 
 Other Investment Companies. A Fund may invest in securities of other invest-
 ment companies subject to the limitations prescribed by the Act. These limi-
 tations include a prohibition on any Fund acquiring more than 3% of the vot-
 ing shares of any other investment company, and a prohibition on investing
 more than 5% of a Fund's total assets in securities of any one investment
 company or more than 10% of its total assets in securities of all investment
 companies. A Fund will indirectly bear its proportionate share of any man-
 agement fees and other expenses paid by such other investment companies.
 Such other investment companies will have investment objectives, policies
 and restrictions substantially similar to those of the acquiring Fund and
 will be subject to substantially the same risks.
 
 Non-Investment Grade Fixed-Income Securities. Non-investment grade fixed-
 income securities and unrated securities of comparable credit quality (com-
 monly known as "junk bonds") are considered predominantly speculative by
 traditional investment standards. In some cases, these obligations may be
 highly speculative and have poor prospects for reaching investment grade
 standing. Non-investment grade fixed-income securities are subject to the
 increased risk of an issuer's inability to meet principal and interest obli-
 gations. These securities, also referred to as high yield securities, may be
 subject to greater price volatility due to such factors as specific corpo-
 rate developments, interest rate sensitivity, negative perceptions of the
 junk bond markets generally and less secondary market liquidity.
 
 Non-investment grade fixed-income securities are often issued in connection
 with a corporate reorganization or restructuring or as part of a merger,
 acquisition, takeover or similar event. They are also issued by less estab-
 lished companies seeking to expand. Such issuers are often highly leveraged
 and generally less able than more established or less leveraged entities to
 make scheduled payments of principal and interest in the event of adverse
 developments or business conditions.

                                                                      APPENDIX A
 
 The market value of non-investment grade fixed-income securities tends to
 reflect individual corporate developments to a greater extent than that of
 higher rated securities which react primarily to fluctuations in the general
 level of interest rates. As a result, a Fund's ability to achieve its
 investment objectives may depend to a greater extent on the Investment
 Adviser's judgment concerning the creditworthiness of issuers than funds
 which invest in higher-rated securities. Issuers of non-investment grade
 fixed-income securities may not be able to make use of more traditional
 methods of financing and their ability to service debt obligations may be
 affected more adversely than issuers of higher-rated securities by economic
 downturns, specific corporate developments or the issuer's inability to meet
 specific projected business forecasts. Negative publicity about the junk
 bond market and investor perceptions regarding lower rated securities,
 whether or not based on fundamental analysis, may depress the prices for
 such securities.
 
 A holder's risk of loss from default is significantly greater for non-
 investment grade fixed-income securities than is the case for holders of
 other debt securities because such non-investment grade securities are gen-
 erally unsecured and are often subordinated to the rights of other creditors
 of the issuers of such
 securities. Investment by a Fund in defaulted securities poses additional
 risk of loss should nonpayment of principal and interest continue in respect
 of such securities. Even if such securities are held to maturity, recovery
 by a Fund of its initial investment and any anticipated income or apprecia-
 tion is uncertain.
 
 The secondary market for non-investment grade fixed-income securities is
 concentrated in relatively few market makers and is dominated by institu-
 tional investors, including mutual funds, insurance companies and other
 financial institutions. Accordingly, the secondary market for such securi-
 ties is not as liquid as, and is more volatile than, the secondary market
 for higher-rated securities. In addition, market trading volume for high
 yield fixed-income securities is generally lower and the secondary market
 for such securities could shrink or disappear suddenly and without warning
 as a result of adverse market or economic conditions, independent of any
 specific adverse changes in the condition of a particular issuer. Because of
 the lack of sufficient market liquidity, a Fund may incur losses because it
 will be required to effect sales at a disadvantageous time and then may at a
 substantial drop in price. These factors may have an adverse effect on the
 market price and a Fund's ability to dispose of particular portfolio invest-
 ments. A less liquid secondary market also may make it more difficult for a
 Fund to obtain precise valuations of the high yield securities in its port-
 folio.
 
 Credit ratings issued by credit rating agencies are designed to evaluate the
 safety of principal and interest payments of rated securities. They do not,
 however, evaluate the market value risk of non-investment grade securities
 and, therefore, may
 
                                                                              93

 not fully reflect the true risks of an investment. In addition, credit rat-
 ing agencies may or may not make timely changes in a rating to reflect
 changes in the economy or in the conditions of the issuer that affect the
 market value of the security. Consequently, credit ratings are used only as
 a preliminary indicator of investment quality. Investments in non-investment
 grade and comparable unrated obligations will be more dependent on the
 Investment Adviser's credit analysis than would be the case with investments
 in investment-grade debt obligations.
 
 Loan Participations. A loan participation is an interest in a loan to a U.S.
 or foreign company or other borrower which is administered and sold by a
 financial intermediary. A Fund may only invest in loans to issuers in whose
 obligations it may otherwise invest. Loan participation interests may take
 the form of a direct or co-lending relationship with the corporate borrower,
 an assignment of an interest in the loan by a co-lender or another partici-
 pant, or a participation in the seller's share of the loan. When a Fund acts
 as co-lender in connection with a participation interest or when it acquires
 certain participation interests, the Fund will have direct recourse against
 the borrower if the borrower fails to pay scheduled principal and interest.
 In cases where the Fund lacks direct recourse, it will look to the agent
 bank to enforce appropriate credit remedies against the borrower. In these
 cases, the Fund may be subject to delays, expenses and risks that are
 greater than those that would have been involved if the Fund had purchased a
 direct obligation (such as commercial paper) of such borrower. Moreover,
 under the terms of the loan participation, the Fund may be regarded as a
 creditor of the agent bank (rather than of the underlying corporate borrow-
 er), so that the Fund may also be subject to the risk that the agent bank
 may become insolvent.
 
 Preferred Stock, Warrants and Rights. Certain Funds may invest in preferred
 stock, warrants and rights.Preferred stocks are securities that represent an
 ownership interest providing the holder with claims on the issuer's earnings
 and assets before common stock owners but after bond owners. Unlike debt
 securities, the obligations of an issuer of preferred stock, including divi-
 dend and other payment obligations, may not typically be accelerated by the
 holders of such preferred stock on the occurrence of an event of default or
 other non-compliance by the issuer of the preferred stock.
 
 Warrants and other rights are options to buy a stated number of shares of
 common stock at a specified price at any time during the life of the war-
 rant. The holders of warrants and rights have no voting rights, receive no
 dividends and have no rights with respect to the assets of the issuer.

 Appendix B
 Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

General Investment Management Approach
 
 Goldman Sachs Asset Management, a separate operating division of Goldman,
 Sachs & Co. ("Goldman Sachs"), serves as investment adviser to the Short
 Duration Tax-Free and Core Fixed Income Funds. Goldman Sachs Funds Manage-
 ment, L.P. serves as investment adviser to the Adjustable Rate Government
 and Short Duration Government Funds. Goldman Sachs Asset Management and
 Goldman Sachs Funds Management, L.P. are each referred to in this Prospectus
 as the "Investment Adviser."
 
 Goldman Sachs' Fixed Income Investing Philosophy:
 Active Management Within a Risk-Managed Framework
 The Investment Adviser employs a disciplined, multi-step process to evaluate
 potential investments:
 1. Sector Allocation--The Investment Adviser assesses the relative value of
 different investment sectors (such as U.S. corporate, asset-backed and mort-
 gage-backed securities) to create investment strategies that meet each
 Fund's objectives.
 2. Security Selection--In selecting securities for each Fund, the Investment
 Adviser draws on the extensive resources of Goldman Sachs, including fixed-
 income and equity research professionals.
 3. Yield Curve Strategies--The Investment Adviser adjusts the term structure
 of the Funds based on its expectations of changes in the shape of the yield
 curve while closely controlling the overall duration of the Fund.
 
 The Investment Adviser de-emphasizes interest rate predictions as a means of
 generating incremental return. Instead, the Investment Adviser seeks to add
 value through the selection of particular securities and investment sector
 allocation as described above.
 
 With every fixed-income portfolio, the Investment Adviser applies a team
 approach that emphasizes risk management and capitalizes on Goldman Sachs'
 extensive research capabilities.

                                                                               1
<PAGE>
 
 
 
 
 Each of the Funds described in this Prospectus has a target duration. A
 Fund's duration approximates its price sensitivity to changes in interest
 rates. Maturity measures the time until final payment is due; it takes no
 account of the pattern of a security's cash flows over time. In computing
 portfolio duration, a Fund will estimate the duration of obligations that
 are subject to prepayment or redemption by the issuer, taking into account
 the influence of interest rates on prepayments and coupon flows. This method
 of computing duration is known as "option-adjusted" duration. A Fund will
 not be limited as to its maximum weighted average portfolio maturity or the
 maximum stated maturity with respect to individual securities unless other-
 wise noted.
 
 Each Fund also has credit rating requirements for the securities it buys. A
 Fund will deem a security to have met its minimum credit rating requirement
 if the security has the required rating at the time of purchase from at
 least one nationally recognized statistical rating organization ("NRSRO")
 even though it has been rated below the minimum rating by one or more other
 NRSROs. Unrated securities may be purchased by the Funds if they are deter-
 mined by the Investment Adviser to be of comparable quality. If a security
 satisfies a Fund's minimum rating requirement at the time of purchase and is
 subsequently downgraded below such rating, the Fund will not be required to
 dispose of such security. If a downgrade occurs, the Investment Adviser will
 consider what action, including the sale of such security, is in the best
 interests of a Fund and its shareholders.

 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal circumstances, at least 65% of its total
 assets in securities issued or guaranteed by the U.S. government, its agen-
 cies, instrumentalities or sponsored enterprises ("U.S. Government Securi-
 ties") that are adjustable rate mortgage pass-through securities and other
 mortgage securities with periodic interest rate resets. The remainder of the
 Fund's assets (up to 35%) may be invested in other U.S. Government Securi-
 ties, including:
 .Fixed rate mortgage pass-through securities
 .Other securities representing an interest in or collateralized by adjust-
  able rate and fixed rate mortgage loans ("Mortgage-Backed Securities")
 .Repurchase agreements collateralized by U.S Government Securities
 
 Substantially all of the Fund's assets will be invested in U.S. Government

 denominated securities.
 
 Duration (under normal interest rate conditions):
 Target = Six-Month to One-Year U.S. Treasury Security
 Maximum = 2 Years
 
 Expected Approximate Interest Rate Sensitivity: 9-month U.S. Treasury bill
 
 Credit Quality: U.S. Government Securities and repurchase agreements collat-
 eralized by such securities
 
 Benchmarks: Six-month and One-Year U.S. Treasury Security
 
                                                                               3
<PAGE>
 
Goldman Sachs Short Duration Government Fund

 current income, may also consider the potential for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal market conditions, at least 65% of its total
 assets in U.S. Government Securities and in repurchase agreements collater-
 alized by such securities. Substantially all of the Fund's assets will be
 invested in U.S. Government Securities. 100% of the Fund's portfolio will be
 invested in U.S. dollar-denominated securities.
 
 Duration (under normal interest rate conditions):
 Target = Two-Year U.S. Treasury Security plus or minus 0.5 years

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
Goldman Sachs Short Duration Tax-Free Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a high level of current income, consistent with relatively
 low volatility of principal, that is exempt from regular federal income tax.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal conditions, at least 80% of its net assets in
 fixed-income securities issued by or on behalf of states, territories and
 possessions of the United States (including the District of Columbia) and
 the political subdivisions, agencies and instrumentalities thereof ("Munici-
 pal Securities"), the interest on which is exempt from regular federal
 income tax (i.e., excluded from gross income for federal income tax purpos-
 es), and is not a tax preference item under the federal alternative minimum
 tax. Under normal circumstances, the Fund's investments in private activity
 bonds and taxable investments will not exceed, in the aggregate, 20% of the
 Fund's net assets. The interest from private activity bonds (including the
 Fund's distributions of such interest) may be a preference item for purposes
 of the federal alternative minimum tax. 100% of the Fund's portfolio will be
 invested in U.S. dollar-denominated securities.
 
 Duration (under normal interest rate conditions):
 Target = Lehman Brothers Three-Year Municipal Bond Index plus or minus 0.5
 years
 Maximum = 4 years
 
 Expected Approximate Interest Rate Sensitivity: 3-year municipal bond
 
 Credit Quality:
 Minimum = BBB or Baa by a NRSRO at the time of purchase, or, if unrated,
 determined by the Investment Adviser to be of comparable quality
 
 Benchmark: Lehman Brothers Three-Year Municipal Bond Index
 
                                                                               5
<PAGE>
 
Goldman Sachs Core Fixed Income Fund
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks a total return consisting of capital appreciation and income
 that exceeds the total return of the Lehman Brothers Aggregate Bond Index
 (the "Index").
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 The Fund invests, under normal circumstances, at least 65% of its total
 assets in fixed-income securities, including U.S. Government Securities,
 corporate debt securities, Mortgage-Backed Securities and asset-backed secu-
 rities. The Fund may also invest in custodial receipts, Municipal Securities
 and convertible securities. The Fund's investments in non-U.S. dollar denom-
 inated obligations will not exceed 25% of its total assets at the time of
 investment, of which 10% may be invested in obligations of issuers in coun-
 tries with emerging markets or economies ("emerging countries"). In pursuing
 its investment objective, the Fund uses the Index as its performance bench-
 mark, but the Fund will not attempt to replicate the Index. The Fund may,
 therefore, invest in securities that are not included in the Index.
 
 Duration (under normal interest rate conditions):
 Target = Lehman Brothers Aggregate Bond Index plus or minus one year
 Maximum = 6 years
 
 Expected Approximate Interest Rate Sensitivity: 5-year U.S. Treasury note
 
 Credit Quality:
 Minimum = BBB or Baa; Minimum for non-U.S. dollar denominated securities =
 AA or Aa
 Securities will either be rated by an NRSRO or, if unrated, determined by
 the Investment Adviser to be of comparable quality
 
 Benchmark: Lehman Brothers Aggregate Bond Index

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other governmental agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

All Funds:
 
 .Interest Rate Risk--The risk that when interest rates increase, fixed-income
 securities held by a Fund will decline in value. Long-term fixed-income
 securities will normally have more price volatility because of this risk than
 short-term securities.
 .Credit/Default Risk--The risk that an issuer of fixed-income securities held
 by a Fund (which may have low credit ratings) may default on its obligation to
 pay interest and repay principal.
 .Call Risk--The risk that an issuer will exercise its right to pay principal on
 an obligation held by a Fund (such as a Mortgage-Backed Security) earlier than
 
                                                                               9

 expected. This may happen when there is a decline in interest rates. Under
 these circumstances, a Fund may be unable to recoup all of its initial
 investment and will also suffer from having to reinvest in lower yielding
 securities.
 .Extension Risk--The risk that an issuer will exercise its right to pay
 principal on an obligation held by a Fund (such as a Mortgage-Backed Security)
 later than expected. This may happen when there is a rise in interest rates.
 Under these circumstances, the value of the obligation will decrease, and a
 Fund will also suffer from the inability to invest in higher yielding
 securities.
 .Derivatives Risk--The risk that loss may result from a Fund's investments in
 options, futures, swaps, structured securities and other derivative
 investments. These investments may be leveraged so that small changes may
 produce disproportionate losses to a Fund.
 .U. S. Government Securities Risk--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 .Market Risk--The risk that the value of the securities in which a Fund invests
 may go up or down in response to the prospects of individual companies and/or
 general economic conditions. Price changes may be temporary or last for
 extended periods.
 .Management Risk--The risk that a strategy used by the Investment Adviser may
 fail to produce the intended results.
 .Liquidity Risk--The risk that a Fund will not be able to pay redemption
 proceeds within the time period stated in this Prospectus, because of unusual
 market conditions, an unusually high volume of redemption requests, or other
 reasons. Funds that invest in emerging country issuers will be especially
 subject to the risk that during certain periods the liquidity of particular
 issuers or industries, or all securities within this investment category, will
 shrink or disappear suddenly and without warning as a result of adverse
 economic, market or political events, or adverse investor perceptions whether
 or not accurate.
 .Other Risks--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Specific Funds:
 
 .Foreign Risks--The Core Fixed Income Fund will be subject to risks of loss
 with respect to its foreign investments that are not typically associated with
 domestic issuers. Loss may result because of less foreign government
 regulation, less public information and less economic, political and social
 stability. Loss may also result

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 from the imposition of exchange controls, confiscations and other government
 restrictions. The Fund will also be subject to the risk of negative foreign
 currency rate fluctuations. Foreign risks will normally be greatest when a
 Fund invests in issuers located in emerging countries.
 .Emerging Markets Risk--The Core Fixed Income Fund may invest in emerging
 countries. The securities markets of Asian, Latin American, Eastern European,
 African and other emerging countries are less liquid, are especially subject
 to greater price volatility, have smaller market capitalizations, have less
 government regulation and are not subject to as extensive and frequent
 accounting, financial and other reporting requirements as the securities
 markets of more developed countries. Further, investment in equity securities
 of issuers located in Russia and certain other emerging countries involves
 risk of loss resulting from problems in share registration and custody and
 substantial economic and political disruptions. These risks are not normally
 associated with investment in more developed countries.
 .Tax Risk--The Short Duration Tax-Free Fund may be more adversely impacted by
 changes in tax rates and policies than the other Funds. Because interest
 income from Municipal Securities is normally not subject to regular federal
 income taxation, the attractiveness of Municipal Securities in relation to
 other investment alternatives is affected by changes in federal income tax
 rates applicable to, or the continuing federal income tax-exempt status of,
 such interest income. Any proposed or actual changes in such rates or exempt
 status, therefore, can significantly affect the demand for and supply,
 liquidity and marketability of Municipal Securities. This could, in turn,
 affect the Fund's ability to acquire and dispose of Municipal Securities at
 desirable yield and price levels.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

 Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Admin-
 istration Shares from year to year; and (b) how the average annual returns
 of a Fund's Administration Shares compare to those of broad-based securities
 market indices. The bar chart and table assume reinvestment of dividends and
 distributions. A Fund's past performance is not necessarily an indication of
 how the Fund will perform in the future. Performance reflects expense limi-
 tations in effect. If expense limitations were not in place, a Fund's per-
 formance would have been reduced.

The following Example is intended to help you compare the cost of investing in
a Fund (without the waivers and expense limitations) with the cost of investing
in other mutual funds. The Example assumes that you invest $10,000 in Adminis-
tration Shares of a Fund for the time periods indicated and then redeem all of
your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that a Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

Service Organizations that invest in Administration Shares on behalf of their
customers may charge other fees directly to their customer accounts in connec-
tion with their investments. You should contact your Service Organization for
information regarding such charges. Such fees, if any, may affect the return
such customers realize with respect to their investments.
 
Certain Service Organizations may receive other compensation in connection with
the sale and distribution of Administration Shares or for services to their
customers' accounts and/or the Funds. For additional information regarding such
compensation, see "Shareholder Guide" in the Prospectus and "Other Information"

 GSAM is a separate operating division of Goldman Sachs, which registered as
 an investment adviser in 1981. GSFM, a registered investment adviser since
 1990, is a Delaware limited partnership which is an affiliate of Goldman
 Sachs. As of December 31, 1998, GSAM and GSFM, together with their affili-
 ates, acted as investment adviser or distributor for assets in excess of
 $195 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser makes the investment decisions
 for the Funds and places purchase and sale orders for the Funds' portfolio
 transactions in U.S. and foreign markets. As permitted by applicable law,
 these orders may be directed to any brokers, including Goldman Sachs and its
 affiliates. While the Investment Adviser is ultimately responsible for the
 management of the Funds, it is able to draw upon the research and expertise
 of its asset management affiliates for portfolio decisions and management
 with respect to certain portfolio securities. In addition, the Investment
 Adviser has access to the research and certain proprietary technical models
 developed by Goldman Sachs, and will apply quantitative and qualitative
 analysis in determining the appropriate allocations among categories of
 issuers and types of securities.
 
 The Investment Adviser also performs the following additional services for
 the Funds:
 .Supervises all non-advisory operations of the Funds
 .Provides personnel to perform necessary executive, administrative and
  clerical services to the Funds

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to a Fund or limit a Fund's investment activities. Goldman Sachs and its
 affiliates engage in proprietary trading and advise accounts and funds which
 have investment objectives similar to those of the Funds and/or which engage
 in and compete for transactions in the same types of securities, currencies
 and instruments as the Funds. Goldman Sachs and its affiliates will not have
 any obligation to make available any information regarding their proprietary
 activities or strategies, or the activities or strategies used for other
 accounts managed by them, for the benefit of the management of the Funds.
 The results of a Fund's investment activities, therefore, may differ
 
                                                                              23
<PAGE>
 
 
 from those of Goldman Sachs and its affiliates, and it is possible that a
 Fund could sustain losses during periods in which Goldman Sachs and its
 affiliates and other accounts achieve significant profits on their trading
 for proprietary or other accounts. In addition, the Funds may, from time to
 time, enter into transactions in which other clients of Goldman Sachs have
 an adverse interest. A Fund's activities may be limited because of regula-
 tory restrictions applicable to Goldman Sachs and its affiliates, and/or
 their internal policies designed to comply with such restrictions.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However,

                                                               SERVICE PROVIDERS
 
 the Investment Adviser is not in a position to verify the accuracy or com-
 pleteness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.
 
                                                                              25

Dividends
 
Over the course of the fiscal year, dividends accrued and paid will constitute
all or substantially all of the Funds' net investment income. The Funds also
intend that all net realized capital gains (after taking into account any
available capital loss carryovers) will be declared as a dividend at least
annually. You may choose to have dividends paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 .Shares of the same or an equivalent class of another Goldman Sachs Fund.
 Special restrictions may apply for certain ILA Portfolios. See the Additional
 Statement.
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time before the record date for a
particular dividend or distribution. If you do not indicate any choice, your
dividends and distributions will be reinvested automatically in the applicable
Fund. If cash dividends are elected with respect to the Fund's monthly net
investment income dividends, then cash dividends must also be elected with
respect to the non-long-term capital gains component, if any, of the Fund's
annual dividend.
 
The election to reinvest dividends and distributions in additional shares will
not affect the tax treatment of such dividends and distributions, which will be
treated as received by you and then used to purchase the shares.
 
Dividends from net investment income and distributions from capital gains are
declared and paid as follows:

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Administration
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Administration Shares Of The Funds?
 Generally, Administration Shares may be purchased only through institutions
 that have agreed to provide account administration and maintenance services
 to their customers who are the beneficial owners of Administration Shares.
 These institutions are called "Service Organizations." Customers of a Serv-
 ice Organization will normally give their purchase instructions to the Serv-
 ice Organization, and the Service Organization will, in turn, place purchase
 orders with Goldman Sachs. Service Organizations will set times by which
 purchase orders and payments must be received by them from their customers.
 Generally, Administration Shares may be purchased from the Funds on any
 business day at their net asset value ("NAV") next determined after receipt
 of an order by Goldman Sachs from a Service Organization. No sales load is
 charged. Purchases of Administration Shares must be settled within three
 business days of receipt of a complete purchase order.
 
 Service Organizations are responsible for transmitting purchase orders and
 payments to Goldman Sachs in a timely fashion. Service Organizations should
 place an order with Goldman Sachs at 1-800-621-2550 and either:
 .Wire federal funds to The Northern Trust Company ("Northern"), as
  subcustodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian) on the next business day; or
 .Initiate an Automated Clearing House Network ("ACH") transfer to Northern;
  or
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds--(Name
  of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago, IL
  60606-6372. The Fund will not accept a check drawn on a foreign bank or a
  third-party check.
 
 What Do I Need To Know About Service Organizations?
 Service Organizations may provide the following services in connection with
 their customers' investments in Administration Shares:
 .Acting, directly or through an agent, as the sole shareholder of record
 .Maintaining account records for customers
 .Processing orders to purchase, redeem or exchange shares for customers
 
                                                                              27
<PAGE>
 
 
 In addition, some (but not all) Service Organizations are authorized to
 accept, on behalf of Goldman Sachs Trust (the "Trust"), purchase, redemption
 and exchange orders placed by or on behalf of their customers, and may des-
 ignate other intermediaries to accept such orders, if approved by the Trust.
 In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized Service Organization or intermediary on
  a business day, and the order will be priced at the Fund's NAV next deter-
  mined after such acceptance.
 .Service Organizations or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your Service Organization directly to learn whether it is
 authorized to accept orders for the Trust.
 
 Pursuant to an administration plan adopted by the Trust's Board of Trustees,
 Service Organizations are entitled to receive payment for their services
 from the Trust of up to 0.25% (on an annualized basis) of the average daily
 net assets of the Administration Shares of the Funds, which are attributable
 to or held in the name of the Service Organization for its customers.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Service Organizations and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Service
 Organizations depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses. Additional
 compensation based on sales may, but is currently not expected to, exceed
 0.50% (annualized) of the amount invested.
 
 In addition to Administration Shares, each Fund also offers other classes of
 shares to investors. These other share classes are subject to different fees
 and expenses (which affect performance), have different minimum investment
 requirements and are entitled to different services than Administration
 Shares. Information regarding these other share classes may be obtained from
 your sales representative or from Goldman Sachs by calling the number on the
 back cover of this Prospectus.

                                                               SHAREHOLDER GUIDE
 
 
 What Is My Minimum Investment In The Funds?
 The Funds do not have any minimum purchase or account requirements with
 respect to Administration Shares. A Service Organization may, however,
 impose a minimum amount for initial and subsequent investments in Adminis-
 tration Shares, and may establish other requirements such as a minimum
 account balance. A Service Organization may redeem Administration Shares
 held by non-complying accounts, and may impose a charge for any special
 services.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Reject or restrict any purchase or exchange orders by a particular pur-
  chaser (or group of related purchasers). This may occur, for example, when
  a pattern of frequent purchases, sales or exchanges of Administration
  Shares of a Fund is evident, or if purchases, sales or exchanges are, or a
  subsequent abrupt redemption might be, of a size that would disrupt the
  management of a Fund.
 
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Administration
 Shares is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _______________________________
                 Number of Outstanding Shares of the Class
 
 The Funds' investments are valued based on market quotations, which may be
 furnished by a pricing service or provided by securities dealers. If accu-
 rate quotations are not readily available, the fair value of the Funds'
 investments may be determined based on yield equivalents, a pricing matrix
 or other sources, under valuation procedures established by the Trustees.
 Debt obligations with a remaining maturity of 60 days or less are valued at
 amortized cost.
 
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). This occurs after the determination, if
  any, of the income to be declared as a dividend. Fund shares will not be
  priced on any day the New York Stock Exchange is closed.
 .When you buy shares, you pay the NAV next calculated after the Funds
  receive your order in proper form.
 
                                                                              29
<PAGE>
 
 .When you sell shares, you receive the NAV next calculated after the Funds
  receive your order in proper form.
 
 Note: The time at which transactions and shares are priced and the time by
 which orders must be received may be changed in case of an emergency or if
 regular trading on the New York Stock Exchange is stopped at a time other
 than 4:00 p.m. New York time.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 When Will Shares Be Issued And Dividends Begin To Be Paid?
 .Shares Purchased by Federal Funds Wire or ACH Transfer:
    .If a purchase order in proper form specifies a settlement date and is
     received before the Fund's NAV is determined that day, shares will be
     issued and dividends will begin to accrue on the purchased shares on the
     later of (i) the business day after the purchase order is received; or
     (ii) the day that the federal funds wire or ACH transfer is received by
     Northern.
    .If a purchase order in proper form does not specify a settlement date,
     shares will be issued and dividends will begin to accrue on the business
     day after payment is received.
 
 .Shares Purchased by Check or Federal Reserve Draft:
    .If a purchase order in proper form specifies a settlement date and is
     received before the Fund's NAV is determined that day, shares will be
     issued and dividends will begin to accrue on the business day after pay-
     ment is received.
    .If a purchase order in proper form does not specify a settlement date,
     shares will be issued and dividends will begin to accrue on the business
     day after payment is received.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Administration Shares Of The Funds?
 Generally, Administration Shares may be sold (redeemed) only through Service
 Organizations. Customers of a Service Organization will normally give their
 redemption instructions to the Service Organization, and the Service Organi-
 zation will, in turn, place redemption orders with the Funds. Generally,
 each Fund will redeem its Administration Shares upon request on any business
 day at their NAV next determined after receipt of such request in proper
 form. Redemption proceeds may be sent to recordholders by check or by wire
 (if the wire instructions are on record).

 A Service Organization may request redemptions in writing or by telephone if
 the optional telephone redemption privilege is not declined on the Account
 Application.

 --------------------------------------------------------
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request will be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
 How Are Redemption Proceeds Paid?
 By Wire: The Funds will arrange for redemption proceeds to be wired as fed-
 eral funds to the bank account designated in the recordholder's Account
 Application. The following general policies govern wiring redemption pro-
 ceeds:
 .Redemption proceeds will normally be wired on the next business day in fed-
  eral funds (for a total of one business day delay), but may be paid up to
  three business days following receipt of a properly executed wire transfer
  redemption request. If the shares to be sold were recently paid for by
  check, the Fund will pay the redemption proceeds when the check has
  cleared, which may take up to 15 days. If the Federal Reserve Bank is
  closed on the day that the redemption proceeds would ordinarily be wired,
  wiring the redemption proceeds may be delayed one additional business day.
 
                                                                              31

 .To change the bank designated on your Account Application, you must send
  written instructions signed by an authorized person designated on the
  Account Application to the Transfer Agent.
 .Neither the Trust, nor Goldman Sachs assumes any responsibility for the
  performance of intermediaries or your Service Organization in the transfer
  process. If a problem with such performance arises, you should deal
  directly with such intermediaries or Service Organizations.
 
 By Check: A recordholder may elect in writing to receive redemption proceeds
 by check. Redemption proceeds paid by check will normally be mailed to the
 address of record within three business days of receipt of a properly exe-
 cuted redemption request. If the shares to be sold were recently paid for by
 check, the Fund will pay the redemption proceeds when the check has cleared,
 which may take up to 15 days.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Administration Shares of each Fund earn dividends declared on the day the
  shares are redeemed.
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Service Organizations are responsible for the timely transmittal of redemp-
  tion requests by their customers to the Transfer Agent. In order to facili-
  tate the timely transmittal of redemption requests, Service Organizations
  may set times by which they must receive redemption requests. Service Orga-
  nizations may also require additional documentation from you.
 
 The Trust reserves the right to:
 .Redeem Administration Shares of any Service Organization whose account bal-
  ance falls below $50 as a result of earlier redemptions. The Funds will not
  redeem Administration Shares on this basis if the value of the account
  falls below the minimum account balance solely as a result of market condi-
  tions. The Fund will give 60 days' prior written notice to allow a Service
  Organization to purchase sufficient additional shares of the Fund in order
  to avoid such redemption.
 .Redeem the shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.

 Can I Exchange My Investment From One Fund To Another?
 A Service Organization may exchange Administration Shares of a Fund at NAV
 for Administration Shares of any other Goldman Sachs Fund. The exchange
 privilege may be materially modified or withdrawn at any time upon 60 days'
 written notice.

  By Telephone:    If you have not declined the telephone redemption
                   privileges on your Account Application:
                   .1-800-621-2550 (8:00 a.m. to 4:00 p.m.
                    New York time)
 -----------------------------------------------------------------------
 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 Shares may be exchanged among accounts with different names, addresses and
 social security or other taxpayer identification numbers only if the
 exchange instructions are in writing and are signed by an authorized person
 designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
                                                                              33
<PAGE>
 
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types Of Reports Will I Be Sent Regarding Investments In Administration
 Shares?
 Service Organizations will receive from the Funds annual reports containing
 audited financial statements and semiannual reports. Service Organizations
 will also be provided with a printed confirmation for each transaction in
 their account and a monthly account statement. A year-to-date statement for
 accounts will be provided upon request made to Goldman Sachs. Service Orga-
 nizations are responsible for providing these or other reports to their cus-
 tomers who are the beneficial owners of Administration Shares in accordance
 with the rules that apply to their accounts with the Service Organizations.

Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Except for exempt-interest dividends paid by the Short Duration Tax-Free
 Fund as described below, Fund distributions are taxable to you as ordinary
 income (unless your investment is in an IRA or other tax-advantaged account)
 to the extent they are attributable to the Fund's net investment income,
 certain net realized foreign exchange gains and net short-term capital
 gains. They are taxable as long-term capital gains to the extent they are
 attributable to the Fund's excess of net long-term capital gains over net
 short-term capital losses. The tax status of any distribution is the same
 regardless of how long you have been in the Fund and whether you reinvest in
 additional shares or take distributions as cash. Certain distributions paid
 by a Fund in January of a given year may be taxable to shareholders as if
 received the prior December 31. The tax status and amounts of distribution
 for each calendar year will be detailed in your annual tax statement from
 the Fund.
 
 At any time, a portion of a Fund's NAV per share may be represented by
 undistributed income or realized or unrealized appreciation of the Fund's
 portfolio securities. Therefore, subsequent distributions on a Fund's shares
 may be available to you, even if the NAV of your shares is, as a result,
 reduced below the cost of these shares and the distributions represent a
 return of your purchase price.
 
 The Core Fixed Income Fund may be subject to foreign withholding or other
 foreign taxes on income or gain from certain foreign securities. In general,
 the Fund may deduct these taxes in computing its taxable income.
 
 The Short Duration Tax-Free Fund expects to distribute "exempt-interest div-
 idends." These dividends will be exempt income for federal income tax pur-
 poses. However, distributions, if any, derived from net long-term capital
 gains of the Short Duration Tax-Free Fund will generally be taxable to you
 as long-term capital gains. Distributions, if any, derived from taxable
 interest income, net short-term capital gains and certain net realized for-
 eign exchange gains will be taxable to you as ordinary income.
 
 Interest on indebtedness incurred by you to purchase or carry shares of the
 Short Duration Tax-Free Fund generally will not be deductible for federal
 income tax purposes.
 
 
                                                                              35
<PAGE>
 
 
 
 You should note that exempt-interest dividends paid by the Short Duration
 Tax-Free Fund may be an item of tax preference for purposes of determining
 your federal alternative minimum tax liability. Exempt-interest dividends
 will also be considered along with other adjusted gross income in determin-
 ing whether any Social Security or railroad retirement payments received by
 you are subject to federal income taxes.
 
 If you receive an exempt-interest dividend on shares that are held by you
 for six months or less, any loss on the sale or exchange of the shares will
 be disallowed to the extent of such dividend amount.
 
 There are certain tax requirements that all Funds must follow in order to
 avoid federal taxation. In its efforts to adhere to these requirements, the
 Funds may have to limit their investment activity in certain types of
 instruments.
 
 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Fund shares may generate a tax liability (unless
 your investment is in an IRA or other tax-advantaged account). Depending
 upon the purchase or sale price of the shares you sell or exchange, you may
 have a gain or a loss on the transaction.
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Fund, based on the
 difference between your tax basis in the shares and the amount you receive
 for them. (To aid in computing your tax basis, you generally should retain
 your account statements for the periods that you hold shares.) Any loss rec-
 ognized on shares held for six months or less will be treated as a long-term
 capital loss to the extent of any capital gain dividends that were received
 with respect to the shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from any Fund (including the Short Dura-
 tion Tax-Free Fund) or on the value of the shares held by you. More tax
 information is provided in the Additional Statement. You should also consult
 your own tax adviser for information regarding all tax consequences applica-
 ble to your investments in the Funds.

Appendix A
Additional Information on Portfolio Risks, Securities and Techniques
 A. General Portfolio Risks
 
 
 The Funds will be subject to the risks associated with fixed-income securi-
 ties. These risks include interest rate risk, credit risk and call/extension
 risk. In general, interest rate risk involves the risk that when interest
 rates decline, the market value of fixed-income securities tends to
 increase. Conversely, when interest rates increase, the market value of
 fixed-income securities tends to decline. Credit risk involves the risk that
 the issuer could default on its obligations, and a Fund will not recover its
 investment. Call risk and extension risk are normally present in adjustable
 rate mortgage loans ("ARMs"), Mortgage-Backed Securities and asset-backed
 securities. For example, homeowners have the option to prepay their mort-
 gages. Therefore, the duration of a security backed by home mortgages can
 either shorten (call risk) or lengthen (extension risk). In general, if
 interest rates on new mortgage loans fall sufficiently below the interest
 rates on existing outstanding mortgage loans, the rate of prepayment would
 be expected to increase. Conversely, if mortgage loan interest rates rise
 above the interest rates on existing outstanding mortgage loans, the rate of
 prepayment would be expected to decrease. In either case, a change in the
 prepayment rate can result in losses to investors.
 
 The Investment Adviser will not consider the portfolio turnover rate a lim-
 iting factor in making investment decisions for a Fund. A high rate of port-
 folio turnover (100% or more) involves correspondingly greater expenses
 which must be borne by a Fund and its shareholders. The portfolio turnover
 rate is calculated by dividing the lesser of the dollar amount of sales or
 purchases of portfolio securities by the average monthly value of a Fund's
 portfolio securities, excluding securities having a maturity at the date of
 purchase of one year or less. See "Financial Highlights" in Appendix B for a
 statement of the Funds' historical portfolio turnover rates.
 
 The following sections provide further information on certain types of secu-
 rities and investment techniques that may be used by the Funds, including
 their associated risks. Additional information is provided in the Additional
 Statement, which is available upon request. Among other things, the Addi-
 tional Statement describes certain fundamental investment restrictions that
 cannot be changed without shareholder approval. You should note, however,
 that all policies not specifically designated as fundamental are non-funda-
 mental and may
 
                                                                              37
<PAGE>
 
 
 be changed without shareholder approval. If there is a change in a Fund's
 investment objective, you should consider whether that Fund remains an
 appropriate investment in light of your then current financial positions and
 needs.
 
 B. Other Portfolio Risks
 
 
 Credit Risks. Debt securities purchased by the Funds may include securities
 (including zero coupon bonds) issued by the U.S. government (and its agen-
 cies, instrumentalities and sponsored enterprises), foreign governments,
 domestic and foreign corporations, banks and other issuers. Some of these
 fixed-income securities are described in the next section below. Further
 information is provided in the Additional Statement.
 
 Debt securities rated BBB or higher by Standard & Poor's or Baa or higher by
 Moody's are considered "investment grade." Securities rated BBB or Baa are
 considered medium-grade obligations with speculative characteristics, and
 adverse economic conditions or changing circumstances may weaken their
 issuers' capacity to pay interest and repay principal. A security will be
 deemed to have met a rating requirement if it receives the minimum required
 rating from at least one such rating organization even though it has been
 rated below the minimum rating by one or more other rating organizations, or
 if unrated by such rating organizations, is determined by the Investment
 Adviser to be of comparable credit quality.
 
 Certain Funds may invest in fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) which are commonly referred to as "junk
 bonds." Junk bonds are considered predominantly speculative and may be ques-
 tionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in a Fund's portfolio is downgraded by a rat-
 ing organization, the market price and liquidity of such security may be
 adversely affected.
 
 Risks of Derivative Investments. A Fund's transactions, if any, in options,
 futures, options on futures, swaps, interest rate caps, floors and collars,
 structured securities, inverse floating-rate securities, stripped mortgage-
 backed securities and currency transactions involve additional risk of loss.
 Loss can result from a lack of correlation between changes in the value of
 derivative instruments and the portfolio assets (if any) being hedged, the
 potential illiquidity of the markets for derivative instruments, or the
 risks arising from margin requirements and related lever-
 
38
<PAGE>
 
                                                                      APPENDIX A
 
 age factors associated with such transactions. The use of these management
 techniques also involves the risk of loss if the Investment Adviser is
 incorrect in its expectation of fluctuations in securities prices, interest
 rates or currency prices. Each Fund may also invest in derivative invest-
 ments for non-hedging purposes (that is, to seek to increase total return),
 which is considered a speculative practice and presents even greater risk of
 loss.
 
 Derivative Mortgage-Backed Securities (such as principal-only ("POs"),
 interest-only ("IOs") or inverse floating rate securities) are particularly
 exposed to call and extension risks. Small changes in mortgage prepayments
 can significantly impact the cash flow and the market value of these securi-
 ties. In general, the risk of faster than anticipated prepayments adversely
 affects IOs, super floaters and premium priced Mortgage-Backed Securities.
 The risk of slower than anticipated prepayments generally adversely affects
 POs, floating-rate securities subject to interest rate caps, support
 tranches and discount priced Mortgage-Backed Securities. In addition, par-
 ticular derivative securities may be leveraged such that their exposure
 (i.e., price sensitivity) to interest rate and/or prepayment risk is
 magnified.
 
 Some floating-rate derivative debt securities can present more complex types
 of derivative and interest rate risks. For example, range floaters are sub-
 ject to the risk that the coupon will be reduced below market rates if a
 designated interest rate floats outside of a specified interest rate band or
 collar. Dual index or yield curve floaters are subject to lower prices in
 the event of an unfavorable change in the spread between two designated
 interest rates.
 
 Risks of Foreign Investments. Foreign investments involve special risks that
 are not typically associated with U.S. dollar denominated or quoted securi-
 ties of U.S. issuers. Foreign investments may be affected by changes in cur-
 rency rates, changes in foreign or U.S. laws or restrictions applicable to
 such investments and changes in exchange control regulations (e.g., currency
 blockage). A decline in the exchange rate of the currency (i.e., weakening
 of the currency against the U.S. dollar) in which a portfolio security is
 quoted or denominated relative to the U.S. dollar would reduce the value of
 the portfolio security. In addition, if the currency in which a Fund
 receives dividends, interest or other payments declines in value against the
 U.S. dollar before such income is distributed as dividends to shareholders
 or converted to U.S. dollars, the Fund may have to sell portfolio securities
 to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts
 
                                                                              39
<PAGE>
 
 
 after January 1, 1999 that refer to existing currencies rather than the
 euro; the establishment and maintenance of exchange rates for currencies
 being converted into the euro; the fluctuation of the euro relative to non-
 euro currencies during the transition period from January 1, 1999 to Decem-
 ber 31, 2001 and beyond; whether the interest rate, tax and labor regimes of
 European countries participating in the euro will converge over time; and
 whether the conversion of the currencies of other countries that now are or
 may in the future become members of the European Union ("EU") may have an
 impact on the euro. These or other factors, including political and economic
 risks, could cause market disruptions, and could adversely affect the value
 of securities held by the Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than a U.S. issuer. In addition, there is generally less government
 regulation of foreign markets, companies and securities dealers than in the
 United States. Foreign securities markets may have substantially less volume
 than U.S. securities markets and securities of many foreign issuers are less
 liquid and more volatile than securities of comparable domestic issuers.
 Furthermore, with respect to certain foreign countries, there is a possibil-
 ity of nationalization, expropriation or confiscatory taxation, imposition
 of withholding or other taxes on dividend or interest payments (or, in some
 cases, capital gains), limitations on the removal of funds or other assets
 of the Funds, and political or social instability or diplomatic developments
 which could affect investments in those countries.
 
 Concentration of a Fund's assets in one or a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations by certain Funds involves risks not
 present in debt obligations of corporate issuers. The issuer of the debt or
 the governmental authorities that control the repayment of the debt may be
 unable or unwilling to repay principal or interest when due in accordance
 with the terms of such
 
40
<PAGE>
 
                                                                      APPENDIX A
 
 debt, and a Fund may have limited recourse to compel payment in the event of
 a default. Periods of economic uncertainty may result in volatility of mar-
 ket prices of sovereign debt, and in turn a Fund's NAV, to a greater extent
 than the volatility inherent in debt obligations of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Risks of Emerging Countries. Certain Funds may invest in securities of
 issuers located in emerging countries. The risks of foreign investment are
 heightened when the issuer is located in an emerging country. Emerging coun-
 tries are generally located in the Asia-Pacific region, Eastern Europe,
 Latin and South America and Africa. A Fund's purchase and sale of portfolio
 securities in certain emerging countries may be constrained by limitations
 as to daily changes in the prices of listed securities, periodic trading or
 settlement volume and/or limitations on aggregate holdings of foreign
 investors. Such limitations may be computed based on the aggregate trading
 volume by or holdings of a Fund, the Investment Adviser, its affiliates and
 their respective clients and other service providers. A Fund may not be able
 to sell securities in circumstances where price, trading or settlement vol-
 ume limitations have been reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, such as Taiwan, it is
 anticipated that a Fund may invest in such countries only through other
 investment funds in such countries.
 
                                                                              41
<PAGE>
 
 
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and ethnic, religious and racial disaffec-
 tion, among other factors, have also led to social unrest, violence and/or
 labor unrest in some emerging countries. Unanticipated political or social
 developments may result in sudden and significant investment losses. Invest-
 ing in emerging countries involves greater risk of loss due to expropria-
 tion, nationalization, confiscation of assets and property or the imposition
 of restrictions on foreign investments and on repatriation of capital
 invested.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of those emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 A Fund's investment in emerging countries may also be subject to withholding
 or other taxes, which may be significant and may reduce the return from an
 investment in such country to the Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve a Fund's
 delivery of securities before receipt of payment for their sale. In addi-
 tion, significant delays are common in certain markets in registering the
 transfer of securities. Settlement or registration problems may make it more
 difficult for a Fund to value its portfolio securities and could cause the
 Fund to miss attractive investment opportunities, to have a portion of its
 assets uninvested or to incur losses due to the failure of a counterparty to
 pay for securities the Fund has delivered or the Fund's inability to com-
 plete its contractual obligations. The creditworthiness of the local securi-
 ties firms used by the Funds in emerging countries may not be as sound as
 the creditworthiness of firms used in more developed countries. As a result,
 the Fund may be subject to a greater risk of loss if a securities firm
 defaults in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make a Fund's investments in such countries less liquid and more
 volatile than invest-
 
42
<PAGE>
 
                                                                      APPENDIX A
 
 ments in countries with more developed securities markets (such as the
 United States, Japan and most Western European countries). A Fund's invest-
 ments in emerging countries are subject to the risk that the liquidity of
 particular investment, or investments generally, in such countries will
 shrink or disappear suddenly and without warning as a result of adverse eco-
 nomic, market or political conditions or adverse investor perceptions,
 whether or not accurate. Because of the lack of sufficient market liquidity,
 a Fund may incur losses because it will be required to effect sales at a
 disadvantageous time and then only at a substantial drop in price. Invest-
 ments in emerging countries may be more difficult to price precisely because
 of these characteristics and lower trading volumes.
 
 A Fund's use of foreign currency management techniques in emerging countries
 may be limited. Due to the limited market for these instruments in emerging
 countries, the Investment Adviser does not currently anticipate that a sig-
 nificant portion of the Funds' currency exposure in emerging countries, if
 any, will be covered by such instruments.
 
 Risks of Illiquid Securities. Each Fund may invest up to 15% of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
 
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped Mortgage-Backed Securities
 .Repurchase agreements and time deposits with a notice or demand period of
  more than seven days
 .Certain over-the-counter options
 .Certain restricted securities, unless it is determined, based upon a review
  of the trading markets for a specific restricted security, that such
  restricted security is eligible for resale pursuant to Rule 144A under the
  Securities Act of 1933 ("144A Securities") and, therefore, is liquid
 
 Investing in 144A Securities may decrease the liquidity of a Fund's portfo-
 lio to the extent that qualified institutional buyers become for a time
 uninterested in purchasing these restricted securities. The purchase price
 and subsequent valuation of restricted and illiquid securities normally
 reflect a discount, which may be significant, from the market price of com-
 parable securities for which a liquid market exists.
 
 Temporary Investment Risks. Each Fund may, for temporary defensive purposes,
 invest a certain percentage of its total assets in:
 
 .U.S. Government Securities
 .Repurchase agreements collateralized by U.S. Government Securities
 
                                                                              43
<PAGE>
 
 
 Certain Funds may invest more than 20% of their respective net assets in
 taxable investments and in investment grade securities for temporary defen-
 sive purposes.
 
 C. Portfolio Securities and Techniques
 
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the Funds, including their associ-
 ated risks. Further information is provided in the Additional Statement,
 which is available upon request.
 
 U.S. Government Securities and Related Custodial Receipts. U.S. Government
 Securities include U.S. Treasury obligations and obligations issued or guar-
 anteed by U.S. government agencies, instrumentalities or sponsored enter-
 prises. U.S. Government Securities may be supported by (a) the full faith
 and credit of the U.S. Treasury (such as the Government National Mortgage
 Association ("Ginnie Mae")); (b) the right of the issuer to borrow from the
 U.S. Treasury (such as securities of the Student Loan Marketing Associa-
 tion); (c) the discretionary authority of the U.S. government to purchase
 certain obligations of the issuer (such as the Federal National Mortgage
 Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation
 ("Freddie Mac")); or (d) only the credit of the issuer. U.S. Government
 Securities also include Treasury receipts, zero coupon bonds and other
 stripped U.S. Government Securities, where the interest and principal compo-
 nents of stripped U.S. Government Securities are traded independently.
 
 Interests in U.S. Government Securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S. govern-
 ment.
 
 Mortgage-Backed Securities. Mortgage-Backed Securities represent direct or
 indirect participations in, or are collateralized by and payable from, mort-
 gage loans secured by real property. Mortgage-Backed Securities can be
 backed by either fixed rate mortgage loans or adjustable rate mortgage
 loans, and may be issued by either a governmental or non-governmental enti-
 ty. Privately issued Mortgage-Backed Securities are normally structured with
 one or more types of "credit enhancement." However, these Mortgage-Backed
 Securities typically do not have the same credit standing as U.S. government
 guaranteed Mortgage-Backed Securities.

 Mortgage-Backed Securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs") and Real Estate Mortgage
 Investment Conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an investor with a specified interest in the cash flow from a
 pool of underlying mortgages or of other Mortgage-Backed Securities. CMOs
 are issued in multiple classes. In most cases, payments of principal are
 applied to the CMO classes in the order of their respective stated maturi-
 ties, so that no principal payments will be made on a CMO class until all
 other classes having an earlier stated maturity date are paid in full. A
 REMIC is a CMO that qualifies for special tax treatment under the Code and
 invests in certain mortgages principally secured by interests in real prop-
 erty and other permitted investments.
 
 Mortgaged-Backed Securities also include stripped Mortgage-Backed Securities
 ("SMBS"), which are derivative multiple class Mortgage-Backed Securities.
 SMBS are usually structured with two different classes: one that receives
 100% of the interest payments and the other that receives 100% of the prin-
 cipal payments from a pool of mortgage loans. The market value of SMBS con-
 sisting entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage loans are generally higher than pre-
 vailing market yields on other Mortgage-Backed Securities because their cash
 flow patterns are more volatile and there is a greater risk that the initial
 investment will not be fully recouped.
 
 Asset-Backed Securities. Asset-backed securities are securities whose prin-
 cipal and interest payments are collateralized by pools of assets such as
 auto loans, credit card receivables, leases, installment contracts and per-
 sonal property. Asset-backed securities are often subject to more rapid
 repayment than their stated maturity date would indicate as a result of the
 pass-through of prepayments of principal on the underlying loans. During
 periods of declining interest rates, prepayment of loans underlying asset-
 backed securities can be expected to accelerate. Accordingly, a Fund's abil-
 ity to maintain positions in such securities will be affected by reductions
 in the principal amount of such securities resulting from prepayments, and
 its ability to reinvest the returns of principal at comparable yields is
 subject to generally prevailing interest rates at that time. Asset-backed
 securities present credit risks that are not presented by Mortgage-Backed
 Securities. This is because asset-backed securities generally do not have
 the benefit of a security interest in collateral that is comparable to mort-
 gage assets. There is the possibility that, in some cases, recoveries on
 repossessed collateral may not be available to support payments on these
 securities. In the event of a default, a Fund may suffer a loss if it cannot
 sell collateral quickly and receive the amount it is owed.

 Municipal Securities. Municipal Securities include bonds, notes, commercial
 paper and other instruments (including participation interests in such secu-
 rities) issued by or on behalf of the states, territories and possessions of
 the United States (including the District of Columbia) and their political
 subdivisions, agencies or instrumentalities, the interest on which, in the
 opinion of bond counsel for the issuers or counsel selected by the Invest-
 ment Adviser, is exempt from regular federal income tax (i.e., excluded from
 gross income for federal income tax purposes but not necessarily exempt from
 federal alternative minimum tax or from state or local taxes). Because of
 their tax-exempt status, the yields and market values of Municipal Securi-
 ties may be more adversely impacted by changes in tax rates and policies
 than taxable fixed-income securities.
 
 Municipal Securities are often issued to obtain funds for various public
 purposes, including the construction of a wide range of public facilities
 such as bridges, highways, housing, hospitals, mass transportation, schools,
 streets and water and sewer works. Municipal Securities include private
 activity bonds, municipal leases, certificates of participation, pre-
 refunded municipal securities and auction rate securities.
 
 The obligations of the issuer to pay the principal of and interest on a
 Municipal Security are subject to the provisions of bankruptcy, insolvency
 and other laws affecting the rights and remedies of creditors, such as the
 Federal Bankruptcy Act, and laws, if any, that may be enacted by Congress or
 state legislatures extending the time for payment of principal or interest
 or imposing other constraints upon the enforcement of such obligations.
 There is also the possibility that, as a result of litigation or other con-
 ditions, the power or ability of the issuer to pay when due the principal of
 or interest on a Municipal Security may be materially affected. Municipal
 lease obligations and certificates of participation are subject to the added
 risk that the governmental lessee will fail to appropriate funds to enable
 it to meet its payment obligations under the lease.
 
 Municipal Securities may be in the form of a tender option bond, which is a
 Municipal Security (generally held pursuant to a custodial arrangement) hav-
 ing a relatively long maturity and bearing interest at a fixed rate substan-
 tially higher than prevailing short-term, tax-exempt rates. The bond is typ-
 ically issued with the agreement of a bank, broker-dealer or other financial
 institution, which grants the security holders the option, at periodic
 intervals, to tender their securities to the institution and receive the
 face value thereof. After payment of a fee to the financial institution that
 provides this option, the security holder effectively holds a demand obliga-
 tion that bears interest at the prevailing short-term, tax-exempt rate. The
 tender option will be taken into account in determining the maturity of the
 tender option bonds and a Fund's average portfolio maturity. There is risk
 that a

                                                                      APPENDIX A
 
 Fund will not be considered the owner of a tender option bond for federal
 income tax purposes, and thus will not be entitled to treat such interest as
 exempt from federal income tax. Certain tender option bonds may be illiquid.
 
 Corporate Debt Obligations; Trust Preferred Securities; Convertible Securi-
 ties. Corporate debt obligations include bonds, notes, debentures and other
 obligations of corporations to pay interest and repay principal, and include
 securities issued by banks and other financial institutions. A trust pre-
 ferred or capital security is a long dated bond (for example, 30 years) with
 preferred features. The preferred features are that payment of interest can
 be deferred for a specified period without initiating a default event. The
 securities are generally senior in claim to standard preferred stock but
 junior to other bondholders.
 
 Convertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than non-convertible securities of similar qual-
 ity. Convertible securities in which a Fund invests are subject to the same
 rating criteria as its other investments in fixed-income securities. Con-
 vertible securities have both equity and fixed-income risk characteristics.
 Like all fixed-income securities, the value of convertible securities is
 susceptible to the risk of market losses attributable to changes in interest
 rates. Generally, the market value of convertible securities tends to
 decline as interest rates increase and, conversely, to increase as interest
 rates decline. However, when the market price of the common stock underlying
 a convertible security exceeds the conversion price of the convertible secu-
 rity, the convertible security tends to reflect the market price of the
 underlying common stock. As the market price of the underlying common stock
 declines, the convertible security, like a fixed-income security, tends to
 trade increasingly on a yield basis, and thus may not decline in price to
 the same extent as the underlying common stock.
 
 Foreign Currency Transactions. A Fund may, to the extent consistent with its
 investment policies, purchase or sell foreign currencies on a cash basis or
 through forward contracts. A forward contract involves an obligation to pur-
 chase or sell a specific currency at a future date at a price set at the
 time of the contract. A Fund may engage in foreign currency transactions for
 hedging purposes and to seek to protect against anticipated changes in
 future foreign currency exchange rates. In addition, a Fund also may enter
 into such transactions to seek to increase total return, which is considered
 a speculative practice.
 
 Some Funds may also engage in cross-hedging by using forward contracts in a
 currency different from that in which the hedged security is denominated or
 quoted if the Investment Adviser determines that there is a pattern of cor-
 relation between the two currencies. A Fund may hold foreign currency
 received in con-
 
                                                                              47
<PAGE>
 
 
 nection with investments in foreign securities when, in the judgment of the
 Investment Adviser, it would be beneficial to convert such currency into
 U.S. dollars at a later date.
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, a Fund's NAV to fluctuate (when the
 Fund's NAV fluctuates, the value of your shares may go up or down). Currency
 exchange rates also can be affected unpredictably by the intervention of
 U.S. or foreign governments or central banks, or the failure to intervene,
 or by currency controls or political developments in the United States or
 abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are not guaranteed by an exchange or clear-
 inghouse, a default on a contract would deprive a Fund of unrealized prof-
 its, transaction costs or the benefits of a currency hedge or could force
 the Fund to cover its purchase or sale commitments, if any, at the current
 market price.
 
 Structured Securities and Inverse Floaters. Structured securities are secu-
 rities whose value is determined by reference to changes in the value of
 specific currencies, interest rates, commodities, indices or other financial
 indicators (the "Reference") or the relative change in two or more Refer-
 ences. The interest rate or the principal amount payable upon maturity or
 redemption may be increased or decreased depending upon changes in the
 applicable Reference. Structured securities may be positively or negatively
 indexed, so that appreciation of the Reference may produce an increase or
 decrease in the interest rate or value of the security at maturity. In addi-
 tion, changes in the interest rates or the value of the security at maturity
 may be a multiple of changes in the value of the Reference. Consequently,
 structured securities may present a greater degree of market risk than other
 types of fixed-income securities, and may be more volatile, less liquid and
 more difficult to price accurately than less complex securities.
 
 Structured securities include, but are not limited to, inverse floating rate
 debt securities ("inverse floaters"). The interest rate on inverse floaters
 resets in the opposite direction from the market rate of interest to which
 the inverse floater is indexed. An inverse floater may be considered to be
 leveraged to the extent that its interest rate varies by a magnitude that
 exceeds the magnitude of the change in the index rate of interest. The
 higher the degree of leverage of an inverse floater, the greater the vola-
 tility of its market value.

 Zero Coupon, Deferred Interest, Pay-In-Kind and Capital Appreciation Bonds.
 Zero coupon, deferred interest, pay-in-kind and capital appreciation bonds
 are issued at a discount from their face value because interest payments are
 typically postponed until maturity. Pay-in-kind securities are securities
 that have interest payable by the delivery of additional securities. The
 market prices of these securities generally are more volatile than the mar-
 ket prices of interest-bearing securities and are likely to respond to a
 greater degree to changes in interest rates than interest-bearing securities
 having similar maturities and credit quality.
 
 Mortgage Dollar Rolls. A mortgage dollar roll involves the sale by a Fund of
 securities for delivery in the current month. The Fund simultaneously con-
 tracts with the same counterparty to repurchase substantially similar (same
 type, coupon and maturity) but not identical securities on a specified
 future date. During the roll period, the Fund loses the right to receive
 principal and interest paid on the securities sold. However, the Fund bene-
 fits to the extent of any difference between (a) the price received for the
 securities sold and (b) the lower forward price for the future purchase
 and/or fee income plus the interest earned on the cash proceeds of the secu-
 rities sold. Unless the benefits of a mortgage dollar roll exceed the
 income, capital appreciation and gain or loss due to mortgage prepayments
 that would have been realized on the securities sold as part of the roll,
 the use of this technique will diminish the Fund's performance.
 
 Successful use of mortgage dollar rolls depends upon the Investment Advis-
 er's ability to predict correctly interest rates and mortgage prepayments.
 If the Investment Adviser is incorrect in its prediction, a Fund may experi-
 ence a loss. For financial reporting and tax purposes, the Funds treat mort-
 gage dollar rolls as two separate transactions: one involving the purchase
 of a security and a separate transaction involving a sale. The Funds do not
 currently intend to enter into mortgage dollar rolls that are accounted for
 as a financing and do not treat them as borrowings.
 
 Options on Securities, Securities Indices and Foreign Currencies. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Fund may write
 (sell) covered call and put options and purchase put and call options on any
 securities in which it may invest or on any securities index comprised of
 securities in which it may invest. A Fund that invests in foreign securities
 may also purchase and sell (write) put and call options on foreign curren-
 cies.
 
 
                                                                              49
<PAGE>
 
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of the Investment Adviser to manage future price fluctu-
 ations and the degree of correlation between the options and securities (or
 currency) markets. If the Investment Adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in a Fund's investment portfolio, the Fund may incur losses that
 it would not otherwise incur. The use of options can also increase a Fund's
 transaction costs. Options written or purchased by the Funds may be traded
 on either U.S. or foreign exchanges or over-the-counter. Foreign and over-
 the-counter options will present greater possibility of loss because of
 their greater liquidity and credit risks.
 
 Yield Curve Options. Each Fund may enter into options on the yield "spread"
 or differential between two securities. Such transactions are referred to as
 "yield curve" options. In contrast to other types of options, a yield curve
 option is based on the difference between the yields of designated securi-
 ties, rather than the prices of the individual securities, and is settled
 through cash payments. Accordingly, a yield curve option is profitable to
 the holder if this differential widens (in the case of a call) or narrows
 (in the case of a put), regardless of whether the yields of the underlying
 securities increase or decrease.
 
 The trading of yield curve options is subject to all of the risks associated
 with the trading of other types of options. In addition, such options pres-
 ent a risk of loss even if the yield of one of the underlying securities
 remains constant, or if the spread moves in a direction or to an extent
 which was not anticipated.
 
 Futures Contracts and Options on Futures Contracts. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 Government Securities), foreign currencies, securities indices and other
 financial instruments and indices. The Funds may engage in futures transac-
 tions on both U.S. and foreign exchanges.
 
 Each Fund may purchase and sell futures contracts, and purchase and write
 call and put options on futures contracts, in order to seek to increase
 total return or to hedge against changes in interest rates, securities
 prices or, to the extent a Fund invests in foreign securities, currency
 exchange rates, or to otherwise manage their

                                                                      APPENDIX A
 
 term structures, sector selection and durations in accordance with their
 investment objectives and policies. Each Fund may also enter into closing
 purchase and sale transactions with respect to such contracts and options. A
 Fund will engage in futures and related options transactions for bona fide
 hedging purposes as defined in regulations of the Commodity Futures Trading
 Commission or to seek to increase total return to the extent permitted by
 such regulations. A Fund may not purchase or sell futures contracts or pur-
 chase or sell related options to seek to increase total return, except for
 closing purchase or sale transactions, if immediately thereafter the sum of
 the amount of initial margin deposits and premiums paid on the Fund's out-
 standing positions in futures and related options entered into for the pur-
 pose of seeking to increase total return would exceed 5% of the market value
 of the Fund's net assets.
 
 Futures contracts and related options present the following risks:
 .While a Fund may benefit from the use of futures and options on futures,
  unanticipated changes in interest rates, securities prices or currency
  exchange rates may result in poorer overall performance than if the Fund
  had not entered into any futures contracts or options transactions.
 .Because perfect correlation between a futures position and portfolio posi-
  tion that is intended to be protected is impossible to achieve, the desired
  protection may not be obtained and a Fund may be exposed to additional risk
  of loss.
 .The loss incurred by a Fund in entering into futures contracts and in writ-
  ing call options on futures is potentially unlimited and may exceed the
  amount of the premium received.
 .Futures markets are highly volatile and the use of futures may increase the
  volatility of a Fund's NAV.
 .As a result of the low margin deposits normally required in futures trad-
  ing, a relatively small price movement in a futures contract may result in
  substantial losses to a Fund.
 .Futures contracts and options on futures may be illiquid, and exchanges may
  limit fluctuations in futures contract prices during a single day.
 .Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to the Fund at the time of entering into the
 transaction. A forward commitment involves entering into a contract to pur-
 chase or sell securities for a fixed price at a future date beyond the cus-
 tomary settlement period.
 
 
                                                                              51
<PAGE>
 
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although a Fund will generally
 purchase securities on a when-issued or forward commitment basis with the
 intention of acquiring securities for its portfolio, a Fund may dispose of
 when-issued securities or forward commitments prior to settlement if the
 Investment Adviser deems it appropriate.
 
 Lending of Portfolio Securities. Securities lending involves the lending of
 securities owned by a Fund to financial institutions such as certain broker-
 dealers. The borrowers are required to secure their loans continuously with
 cash, cash equivalents, U.S. Government Securities or letters of credit in
 an amount at least equal to the market value of the securities loaned. Cash
 collateral may be invested in cash equivalents. If the Investment Adviser
 determines to make securities loans, the value of the securities loaned may
 not exceed 33 1/3% of the value of the total assets of a Fund (including the
 loan collateral).
 
 A Fund may lend its securities to increase its income. A Fund may, however,
 experience delay in the recovery of its securities if the institution with
 which it has engaged in a portfolio loan transaction breaches its agreement
 with the Fund.
 
 Repurchase Agreements. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Fund may enter into repurchase agreements
 with dealers in U.S. Government Securities and member banks of the Federal
 Reserve System which furnish collateral at least equal in value or market
 price to the amount of their repurchase obligation. Some Funds may also
 enter into repurchase agreements involving certain foreign government secu-
 rities.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund are less than the repurchase price and the
 Fund's cost associated with delay and enforcement of the repurchase agree-
 ment. In addition, in the event of bankruptcy of the seller, a Fund could
 suffer additional losses if a court determines that the Fund's interest in
 the collateral is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to a Fund's
 shareholders. In addition, certain Funds, together with other registered
 investment companies having advisory agreements with the Investment Adviser
 or any of its affiliates, may transfer uninvested cash balances into a sin-
 gle joint account, the daily aggregate balance of which will be invested in
 one or more repurchase agreements.

 Borrowings and Reverse Repurchase Agreements. The Funds can borrow money
 from banks and enter into reverse repurchase agreements with banks and other
 financial institutions in amounts not exceeding one-third of its total
 assets. Reverse repurchase agreements involve the sale of securities held by
 a Fund subject to the Fund's agreement to repurchase them at a mutually
 agreed upon date and price (including interest). These transactions may be
 entered into as a temporary measure for emergency purposes or to meet
 redemption requests. Reverse repurchase agreements may also be entered into
 when the Investment Adviser expects that the interest income to be earned
 from the investment of the transaction proceeds will be greater than the
 related interest expense. Borrowings and reverse repurchase agreements
 involve leveraging. If the securities held by a Fund decline in value while
 these transactions are outstanding, the NAV of the Fund's outstanding shares
 will decline in value by proportionately more than the decline in value of
 the securities. In addition, reverse repurchase agreements involve the risk
 that the interest income earned by a Fund (from the investment of the pro-
 ceeds) will be less than the interest expense of the transaction, that the
 market value of the securities sold by a Fund will decline below the price
 the Fund is obligated to pay to repurchase the securities, and that the
 securities may not be returned to the Fund.
 
 Interest Rate Swaps, Mortgage Swaps, Credit Swaps, Currency Swaps and Inter-
 est Rate Caps, Floors and Collars. Interest rate swaps involve the exchange
 by a Fund with another party of their respective commitments to pay or
 receive interest, such as an exchange of fixed-rate payments for floating
 rate payments. Mortgage swaps are similar to interest rate swaps in that
 they represent commitments to pay and receive interest. The notional princi-
 pal amount, however, is tied to a reference pool or pools of mortgages.
 Credit swaps involve the receipt of floating or fixed rate payments in
 exchange for assuming potential credit losses of an underlying security.
 Credit swaps give one party to a transaction the right to dispose of or
 acquire an asset (or group of assets), or the right to receive or make a
 payment from the other party, upon the occurrence of specified credit
 events. Currency swaps involve the exchange of the parties' respective
 rights to make or receive payments in specified currencies. The purchase of
 an interest rate cap entitles the purchaser, to the extent that a specified
 index exceeds a predetermined interest rate, to receive payment of interest
 on a notional principal amount from the party selling such interest rate
 cap. The purchase of an interest rate floor entitles the purchaser, to the
 extent that a specified index falls below a predetermined interest rate, to
 receive payments of interest on a notional principal amount from the party
 selling the interest rate floor. An interest rate collar is the combination
 of a cap and a floor that preserves a certain return within a predetermined
 range of interest rates.
 
 
                                                                              53
<PAGE>
 
 
 Each Fund may enter into swap transactions for hedging purposes or to seek
 to increase total return. The use of interest rate, mortgage, credit and
 currency swaps, as well as interest rate caps, floors and collars, is a
 highly specialized activity which involves investment techniques and risks
 different from those associated with ordinary portfolio securities transac-
 tions. If the Investment Adviser is incorrect in its forecasts of market
 value, interest rates and currency exchange rates, the investment perfor-
 mance of a Fund would be less favorable than it would have been if these
 investment techniques were not used.
 
 Other Investment Companies. A Fund may invest in securities of other invest-
 ment companies subject to the limitations prescribed by the Act. These limi-
 tations include a prohibition on any Fund acquiring more than 3% of the vot-
 ing shares of any other investment company, and a prohibition on investing
 more than 5% of a Fund's total assets in securities of any one investment
 company or more than 10% of its total assets in securities of all investment
 companies. A Fund will indirectly bear its proportionate share of any man-
 agement fees and other expenses paid by such other investment companies.
 Such other investment companies will have investment objectives, policies
 and restrictions substantially similar to those of the acquiring Fund and
 will be subject to substantially the same risks.

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

                                 INTRODUCTION

     Goldman Sachs Trust (the "Trust") is an open-end management investment
company.  The Trust is organized as a Delaware business trust, and is a
successor to a Massachusetts business trust that was combined with the Trust on
April 30, 1997.  The Trustees of the Trust have authority under the Declaration
of Trust to create and classify shares into separate series and to classify and
reclassify any series of shares into one or more classes without further action
by shareholders. Pursuant thereto, the Trustees have created the following
series, among others:  Goldman Sachs Adjustable Rate Government Fund
("Adjustable Rate Government Fund"), Goldman Sachs Short Duration Government
Fund ("Short Duration Government Fund"), Goldman Sachs Short Duration Tax-Free
Fund ("Short Duration Tax-Free Fund"), Goldman Sachs Government Income Fund
("Government Income Fund"), Goldman Sachs Municipal Income Fund ("Municipal
Income Fund"), Goldman Sachs Core Fixed Income Fund ("Core Fixed Income Fund"),
Goldman Sachs Global Income Fund ("Global Income Fund") and Goldman Sachs High
Yield Fund ("High Yield Fund") (each referred to herein as a "Fund" and
collectively as the "Funds").  Each Fund other than the Global Income Fund is a
diversified, open-end management investment company.  The Global Income Fund is
a non-diversified open-end management investment company.  Short Duration
Government Fund, Short Duration Tax-Free Fund and Core Fixed Income Fund are
each authorized to issue six classes of shares: Class A Shares, Class B Shares,
Class C Shares, Service Shares, Institutional Shares and Administration Shares.
Government Income Fund, Municipal Income Fund, Global Income Fund and High Yield
Fund are authorized to issue five classes of shares: Class A Shares, Class B
Shares, Class C Shares, Service Shares and Institutional Shares.  Adjustable
Rate Government Fund is authorized to issue four classes of shares: Class A
Shares, Service Shares, Institutional Shares and Administration Shares.
Additional series may be added in the future from time to time.

     Goldman Sachs Asset Management ("GSAM"), a separate operating division of
Goldman, Sachs & Co. ("Goldman Sachs"), serves as the Investment Adviser to
Short Duration Tax-Free Fund, Government Income Fund, Municipal Income Fund,
Core Fixed Income Fund and High Yield Fund. Goldman Sachs Asset Management
International ("GSAMI"), an affiliate of Goldman Sachs, serves as Investment
Adviser to the Global Income Fund.  Goldman Sachs Funds Management, L.P.
("GSFM"), an affiliate of Goldman Sachs, serves as the Investment Adviser to
Adjustable Rate Government Fund and Short Duration Government Fund.  GSAM, GSAMI
and GSFM are each sometimes referred to herein as the "Investment Adviser" and
collectively herein as the "Investment Advisers."  In addition, Goldman Sachs
serves as each Fund's distributor and transfer agent.  Each Fund's custodian is
State Street Bank and Trust Company.

     Because each Fund's shares may be redeemed upon request of a shareholder on
any business day at net asset value, the Funds offer greater liquidity than many
competing investments, such as certificates of deposit and direct investments in
certain securities in which the respective Fund may invest.  However, unlike
certificates of deposits, shares of the Funds are not insured by the Federal
Deposit Insurance Corporation.

     The following information relates to and supplements the description of
each Fund's investment policies contained in the Prospectuses.  See the
Prospectuses for a fuller description of 

                                      B-2
<PAGE>
 
each Fund's investment objective and policies. Investing in the Funds entails
certain risks and there is no assurance that a Fund will achieve its objective.

     Experienced Management.  Successfully creating and managing a portfolio of
     ----------------------                                                    
securities requires professionals with extensive experience.  Goldman Sachs'
highly skilled portfolio management team brings together many years of
experience in the analysis, valuation and trading of U.S. and foreign fixed-
income securities.

                      INVESTMENT OBJECTIVES AND POLICIES

Adjustable Rate Government Fund and Short Duration Government Fund

     Adjustable Rate Government Fund and Short Duration Government Fund are both
designed for investors who seek a high level of current income, relative
stability of principal and the high credit quality of securities issued or
guaranteed by the U.S. government, its agencies, instrumentalities or sponsored
enterprises ("U.S. Government Securities"), without incurring the administrative
and accounting burdens involved in direct investment.

     Market and economic conditions may affect the investments of Adjustable
Rate Government and Short Duration Government Funds differently than the
investments normally purchased by other types of fixed-income investors.
Relative to U.S. Treasury and non-fluctuating money market instruments, the
market value of adjustable rate mortgage securities in which Adjustable Rate and
Short Duration Government Funds may invest may be adversely affected by
increases in market interest rates. Conversely, decreases in market interest
rates may result in less capital appreciation for adjustable rate mortgage
securities in relation to U.S. Treasury and money market investments.

     High Current Income.  Adjustable Rate Government and Short Duration
     -------------------                                                
Government Funds seek a higher current yield than that offered by money market
funds or by bank certificates of deposit and money market accounts.  However,
the Adjustable Rate and Short Duration Government Funds do not maintain a
constant net asset value per share and are subject to greater fluctuations in
the value of their shares than a money market fund.  Unlike bank certificates of
deposit and money market accounts, investments in shares of the Funds are not
insured or guaranteed by any government agency.  The Adjustable Rate and Short
Duration Government Funds each seek to provide such high current income without
sacrificing credit quality.


     Relative Low Volatility of Principal.  Adjustable Rate Government Fund
     -------------------------------------                                 
seeks to minimize net asset value fluctuations by investing primarily in
adjustable rate mortgage pass-through securities and other mortgage securities
with periodic interest rate resets, maintaining a maximum duration of two years
and a target duration equal to that of a six-month to one-year U.S. Treasury
Security, and utilizing certain active management techniques to seek to hedge
interest rate risk.  Short Duration Government Fund seeks to minimize net asset
value fluctuations by utilizing certain interest rate hedging techniques and by
maintaining a maximum duration of not more than three years.  The duration
target of the Short Duration Government Fund is that of the 2-year U.S. Treasury
Security plus or minus 0.5 years.  There is no assurance that these strategies
for the 

                                      B-3
<PAGE>
 
Adjustable Rate Government Fund and Short Duration Government Fund will be
successful.

     Professional Management and Administration.  Investors who invest in
     -------------------------------------------                         
securities of the Government National Mortgage Association ("Ginnie Mae") and
other mortgage-backed securities may prefer professional management and
administration of their mortgage-backed securities portfolios.  A well-
diversified portfolio of such securities emphasizing minimal fluctuation of net
asset value requires significant active management as well as significant
accounting and administrative resources.  Members of Goldman Sachs' highly
skilled portfolio management team bring together many years of experience in the
analysis, valuation and trading of U.S. fixed-income securities.

Government Income Fund

     Government Income Fund is designed for investors who seek the relatively
high current income, relative safety of principal and the high credit quality of
U.S. Government Securities, without incurring the administrative and account
burdens involved in direct investment.

     Government Income Fund's overall returns are generally likely to move in
the same direction as interest rates.  Therefore, when interest rates decline,
Government Income Fund's return is also likely to decline.  In exchange for
accepting a higher degree of share price fluctuation, investors have the
potential to achieve a higher return from the Government Income Fund than from
shorter-term investments.

     High Current Income.  Government Income Fund is designed to have a higher
     -------------------                                                      
current yield than a money market fund, since it can invest in longer-term,
higher yielding securities, and may utilize certain investment techniques not
available to a money market fund. Similarly, Government Income Fund's yield is
expected to exceed that offered by bank certificates of deposit and money market
accounts.  However, Government Income Fund does not maintain a constant net
asset value per share and is subject to greater fluctuation in the value of its
shares than a money market fund. Unlike bank certificates of deposit and money
market accounts, investments in shares of Government Income Fund are not insured
or guaranteed by any government agency.  Government Income Fund seeks to provide
high current income without, however, sacrificing credit quality.

     Liquidity. Because Government Income Fund's shares may be redeemed upon
     ---------                                                              
request of a shareholder on any business day at net asset value, Government
Income Fund offers greater liquidity than many competing investments such as
certificates of deposit and direct investments in certain securities in which
Government Income Fund may invest.

     A Sophisticated Investment Process.  Government Income Fund's investment
     ----------------------------------                                      
process starts with a review of trends for the overall economy as well as for
different sectors of the U.S. government and mortgage-backed securities markets.
Goldman Sachs' portfolio managers then analyze yield spreads, implied volatility
and the shape of the yield curve.  In planning the Government Income Fund's
portfolio investment strategies, the Investment Adviser is able to draw upon the
economic and fixed-income research resources of Goldman Sachs.  The Investment

                                      B-4
<PAGE>
 
Adviser will use a sophisticated analytical process involving Goldman Sachs'
proprietary mortgage prepayment model and option-adjusted spread model to
structure and maintain the Government Income Fund's investment portfolio.  In
determining the Government Income Fund's investment strategy and in making
market timing decisions, the Investment Adviser will have access to information
from Goldman Sachs' economists, fixed-income analysts and mortgage specialists.

     Convenience of a Fund Structure.  Government Income Fund eliminates many of
     -------------------------------                                            
the complications that direct ownership of U.S. Government Securities and
mortgage-backed securities entails.  Government Income Fund automatically
reinvests all principal payments within  the Fund and distributes only current
income each month, thereby conserving principal and eliminating the investor's
need to segregate and reinvest the principal portion of each payment on his own.

Short Duration Tax-Free and Municipal Income Funds

     Short Duration Tax-Free Fund and Municipal Income Fund (the "Tax Exempt
Funds") are not money market funds.  Each is designed for investors who seek the
tax benefits associated with investing in fixed-income securities issued by or
on behalf of states, territories and possessions of the United States (including
the District of Columbia) and the political subdivisions, agencies and
instrumentalities thereof ("Municipal Securities") and who are able to accept
greater risk with the possibility of higher returns than investors in municipal
money market funds.  While municipal money market funds almost always maintain a
constant net asset value, they must meet stringent high quality credit
standards, their portfolios must be broadly diversified and their portfolio
securities must have remaining maturities of 397 days or less.  An example of an
"eligible" investment for the Tax Exempt Funds is auction rate Municipal
Securities, which generally have higher yields than money market Municipal
Securities, but which typically are not eligible investments for municipal money
market funds.

     In addition, unlike a municipal money market fund, the Tax Exempt Funds'
increased investment flexibility permits their portfolios to be more easily
adjusted to reflect the shape of the current yield curve as well as to respond
to anticipated developments that might affect the shape of the yield curve.

     The Municipal Securities in which the Tax Exempt Funds invest will be
rated, at the time of investment, at least BBB or Baa by a nationally recognized
statistical rating organization ("NRSRO") or, if unrated, will be determined by
the Investment Adviser to be of comparable quality.  Municipal Securities rated
BBB or Baa are considered medium-grade obligations with speculative
characteristics, and adverse economic conditions or changing circumstances may
weaken their issuers' capability to pay interest and repay principal.  The
credit rating assigned to Municipal Securities may reflect the existence of
guarantees, letters of credit or other credit enhancement features available to
the issuers or holders of such Municipal Securities.

     Investors who wish to invest in Municipal Securities may find that a mutual
fund structure offers some important advantages when compared to investing in
individual Municipal Securities, including:

                                      B-5
<PAGE>
 
         .   The ratings given to Municipal Securities by the rating
             organizations are difficult to evaluate.  For example, some
             Municipal Securities with relatively low credit ratings have yields
             comparable to Municipal Securities with much higher ratings.  The
             credit research professionals at Goldman Sachs closely follow
             market events and are well positioned to judge current and expected
             credit conditions of municipal issuers;

         .   Because of the relative inefficiency of the secondary market in
             Municipal Securities, the value of an individual municipal security
             is often difficult to determine.  As such, investors may obtain a
             wide range of different prices when asking for quotes from
             different dealers.  In addition, a dealer may have a large
             inventory of a particular issue that it wants  to reduce.
             Obtaining the best overall prices can require extensive
             negotiation, which is a function performed by the portfolio
             manager;

         .   Market expertise is also an important consideration for municipal
             investors, and because the Tax Exempt Funds take relatively large
             positions in different securities, the Tax Exempt Funds may be able
             to obtain more favorable prices in the Municipal Securities market
             than investors with relatively small positions; and

         .   Industry and geographical diversification are important
             considerations for municipal investors. The Tax Exempt Funds are
             designed to provide this diversification.

Core Fixed Income Fund

     Core Fixed Income Fund is designed for investors seeking a total return
consisting of both income and capital appreciation that exceeds the total return
of the Lehman Brothers Aggregate Bond Index (the "Index"), without incurring the
administrative and accounting burdens involved in direct investment.  Such
investors also prefer liquidity, experienced professional management and
administration, a sophisticated investment process, and the convenience of a
mutual fund structure.  Core Fixed Income Fund may be appropriate as part of a
balanced investment strategy consisting of stocks, bonds and cash or as a
complement to positions in other types of fixed-income investments.

     The Index currently includes U.S. Government Securities and fixed-rate,
publicly issued, U.S. dollar-denominated fixed-income securities rated at least
BBB or Baa by a NRSRO.  Securities rated BBB or Baa are considered medium-grade
obligations with speculative characteristics, and adverse economic conditions or
changing circumstances may weaken their issuers' capability to pay interest and
repay principal.  The securities currently included in the Index have at least
one year remaining to maturity; have an outstanding principal amount of at least
$100 million; and are issued by the following types of issuers, with each
category receiving a different weighting in the Index:  U.S. Treasury; agencies,
authorities or instrumentalities of the U.S. government; issuers of mortgage-
backed securities; utilities; industrial issuers; financial institutions;
foreign issuers; and issuers of asset-backed securities.  The Index is a
trademark of Lehman Brothers.  Inclusion of a security in the Index does not
imply an opinion by Lehman Brothers as to its attractiveness or 

                                      B-6
<PAGE>
 
appropriateness for investment. Although Lehman Brothers obtains factual
information used in connection with the Index from sources which it considers
reliable, Lehman Brothers claims no responsibility for the accuracy,
completeness or timeliness or such information and has no liability to any
person for any loss arising from results obtained from the use of the Index
data.

     Core Fixed Income Fund's overall returns are generally likely to move in
the opposite direction from interest rates.  Therefore, when interest rates
decline, Core Fixed Income Fund's return is likely to increase. Conversely,
when interest rates increase, Core Fixed Income Fund's return is likely to
decline.  However, the Investment Adviser believes that, given the flexibility
of managers to invest in a diversified portfolio of securities, Core Fixed
Income Fund's return is not likely to decline as quickly as that of other fixed-
income funds with a comparable average portfolio duration.  In exchange for
accepting a higher degree of potential share price fluctuation, investors have
the opportunity to achieve a higher return from Core Fixed Income Fund than from
shorter-term investments.

     A number of investment strategies will be used to achieve the Core Fixed
Income Fund's investment objective, including market sector selection,
determination of yield curve exposure, and issuer selection.  In addition, the
Investment Adviser will attempt to take advantage of pricing inefficiencies in
the fixed-income markets. Market sector selection is the underweighting or
overweighting of one or more of the five market sectors (i.e., U.S. Treasuries,
U.S. government agencies, corporate securities, mortgage-backed securities and
asset-backed securities) in which the Fund primarily invests.  The decision to
overweight or underweight a given market sector is based on expectations of
future yield spreads between different sectors.  Yield curve exposure strategy
consists of overweighting or underweighting different maturity sectors to take
advantage of the shape of the yield curve.  Issuer selection is the purchase and
sale of corporate securities based on a corporation's current and expected
credit standing.  To take advantage of price discrepancies between securities
resulting from supply and demand imbalances or other technical factors, the Fund
may simultaneously purchase and sell comparable, but not identical, securities.
The Investment Adviser will usually have access to the research of, and
proprietary technical models developed by, Goldman Sachs and will apply
quantitative and qualitative analysis in determining the appropriate allocations
among the categories of issuers and types of securities.

     A Sophisticated Investment Process.  Core Fixed Income Fund will attempt to
     ----------------------------------                                         
control its exposure to interest rate risk, including overall market exposure
and the spread risk of particular sectors and securities, through active
portfolio management techniques. Core Fixed Income Fund's investment process
starts with a review of trends for the overall economy as well as for different
sectors of the fixed-income securities  markets.  Goldman Sachs' portfolio
managers then analyze yield spreads, implied volatility and the shape of the
yield curve.  In planning Core Fixed Income Fund's portfolio investment
strategies, the Investment Adviser is able to draw upon the economic and fixed-
income research resources of Goldman Sachs. The Investment Adviser will use a
sophisticated analytical process including Goldman Sachs' proprietary mortgage
prepayment model and option-adjusted spread model to assist in structuring and
maintaining Core Fixed Income Fund's investment portfolio.  In determining Core
Fixed Income Fund's investment strategy and making market timing decisions, the
Investment Adviser will have access to input from Goldman Sachs' economists,
fixed-income analysts and mortgage specialists.

Global Income Fund

     Global Income Fund is designed for investors seeking a combination of high
income, capital appreciation, stability of principal, experienced professional
management, flexibility and liquidity.  However, investing in the Fund involves
certain risks, and there is no assurance that the Fund will achieve its
investment objective.  The securities in which the Fund invests will be rated,
at the time of investment, at least BBB or Baa by an NRSRO or, if unrated, will
be determined by the Investment Adviser to be of comparable quality.  Securities
rated BBB or Baa are considered medium-grade obligations with speculative
characteristics, and adverse economic conditions or changing circumstances may
weaken their issuers' capability to pay interest and repay principal.

     In selecting securities for the Fund, portfolio managers consider such
factors as the security's duration, sector and credit quality rating as well as
the security's yield and prospects for capital appreciation.  In determining the
countries and currencies in which the Fund will invest, the Fund's portfolio
managers form opinions based primarily on the views of Goldman Sachs' economists
as well as information provided by securities dealers, including information
relating to factors such as interest rates, inflation, monetary and fiscal
policies, taxation, and political climate.  The portfolio managers apply the
Black-Litterman Model (the "Model") to their views to develop a portfolio that
produces, in the view of the Investment Adviser, the optimal expected return for
a given level of risk.  The Model factors in the opinions of the portfolio
managers, adjusting for their level of confidence in such opinions, with the
views implied by an international capital asset pricing formula.  The Model is
also used to maintain the level of portfolio risk within the guidelines
established by the Investment Adviser.

     High Income.  Global Income Fund's portfolio managers will seek out the
     -----------                                                            
highest yielding bonds in the global fixed-income market that meet the Global
Income Fund's credit quality standards and certain other criteria.

     Capital Appreciation.  Investing in the foreign bond markets offers the
     --------------------                                                   
potential for capital appreciation due to both interest rate and currency
exchange rate fluctuations.  The portfolio managers attempt to identify
investments with appreciation potential by carefully evaluating trends affecting
a country's currency as well as a country's fundamental economic strength.
However, there is a risk of capital depreciation as a result of unanticipated
interest rate and currency fluctuations.

     Portfolio Management Flexibility.  Global Income Fund is actively managed.
     --------------------------------                                           
The Fund's portfolio managers invest in countries that, in their judgment, meet
the Fund's investment guidelines and often have strong currencies and stable
economies and in securities that they believe offer favorable performance
prospects.

     Relative Stability of Principal.  Global Income Fund may be able to reduce
     -------------------------------                                           
principal fluctuation by investing in foreign countries with economic policies
or business cycles different from those of the United States and in foreign
securities markets that do not necessarily move in the same direction or
magnitude as the U.S. market.  Investing in a broad range of U.S. and foreign
fixed-income securities and currencies reduces the dependence of the Fund's
performance on 

                                      B-8
<PAGE>
 
developments in any particular market to the extent that adverse events in one
market are offset by favorable events in other markets. The Fund's policy of
investing primarily in high quality securities may also reduce principal
fluctuation. However, there is no assurance that these strategies will always be
successful.

     Professional Management.  Individual U.S. investors may prefer professional
     -----------------------                                                    
management of their global bond and currency portfolios because a well-
diversified portfolio requires a large amount of capital and because the size of
the global market requires access to extensive resources and a substantial
commitment of time.

High Yield Fund

     High Yield Fund's Investment Process.  A number of investment strategies
     -------------------------------------                                   
are used to seek to achieve the Fund's investment objective, including market
sector selection, determination of yield curve exposure, and issuer selection.
In addition, the Investment Adviser will attempt to take advantage of pricing
inefficiencies in the fixed-income markets.  GSAM starts the investment process
with economic analysis based on research generated by the Goldman Sachs Global
Economic Research Group and others to determine broad growth trends, industry-
specific events and market forecasts.  The market value of non-investment grade
fixed-income securities tends to reflect individual developments within a
company to a greater extent than higher rated corporate debt or Treasury bonds
that react primarily to fluctuations in interest rates.  Therefore, determining
the creditworthiness of issuers is critical.  To that end, the High Yield Fund's
portfolio managers have access to Goldman Sachs highly regarded Credit Research
and Global Investment Research Departments, as well as analysis from the firm's
High Yield Research Group, a dedicated group of 13 professionals in the high
yield and emerging market corporate bond research area, consisting of industry
and regional market specialists.  In addition, the Fund's portfolio managers may
review the opinions of the two largest independent credit rating agencies,
Standard & Poor's Ratings Group ("Standard & Poor's") and Moody's Investors
Services, Inc. ("Moody's") High Yield Fund's portfolio managers and credit
analysts also conduct their own in-depth analysis of each issue considered for
inclusion in the Fund's portfolio.  The portfolio managers and credit analysts
evaluate such factors as a company's competitive position, the strength of its
balance sheet, its ability to withstand economic downturns and its potential to
generate ample cash flow to service its debt. The ability to analyze accurately
a company's future cash flow by correctly anticipating the impact of economic,
industry-wide and specific events are critical to successful high yield
investing. GSAM's goal is to identify companies with the potential to strengthen
their balance sheets by increasing their earnings, reducing their debt or
effecting a turnaround.  GSAM analyzes trends in a company's debt picture (i.e.,
the level of its interest coverage) as well as new developments in its capital
structure on an ongoing basis.  GSAM believes that this ongoing reassessment is
more valuable than relying on a "snapshot" view of a company's ability to
service debt at one or two points in time.

     High Yield Fund's portfolio is diversified among different sectors and
industries on a global basis in an effort to reduce overall risk.  While GSAM
will avoid excessive concentration in any one industry, the Fund's specific
industry weightings are the result of individual security selection.  Emerging
market debt considered for the High Yield Fund's portfolio will be selected by
specialists knowledgeable about the political and economic structure of those
economies.

     Return on and Risks of High Yield Securities.  High yield bonds can deliver
     ---------------------------------------------                              
higher yields and total return than either investment grade corporate bonds or
U.S. Treasury bonds.  However, because these non-investment grade securities
involve higher risks in return for higher income, they are best suited to long-
term investors who are financially secure enough to withstand volatility and the
risks associated with such investments.  See "Other Investments and Practices."
Different types of fixed income securities may react differently to changes in
the economy. High yield bonds, like stocks, tend to perform best when the
economy is strong, inflation is low and companies experience healthy profits,
which can lead to higher stock prices and higher credit ratings.  Government
bonds are likely to appreciate more in a weaker economy when interest rates are
declining.  In certain types of markets, adding some diversification in the high
yield asset class may help to increase returns and decrease overall portfolio
risk.

     For high yield, non-investment grade securities, as for most investments,
there is a direct relationship between risk and return.  Along with their
potential to deliver higher yields and greater capital appreciation than most
other types of fixed income securities, high yield securities are subject to
higher risk of loss, greater volatility and are considered speculative by
traditional investment standards.  The most significant risk associated with
high yield securities is credit risk: the risk that the company issuing a high
yield security may have difficulty in meeting its principal and/or interest
payments on a timely basis.  As a result, extensive credit research and
diversification are essential factors in managing risk in the high yield arena.
To a lesser extent, high yield bonds are also subject to interest rate risk:
when interest rates increase, the value of fixed income securities tends to
decline.

                   OTHER INVESTMENT OBJECTIVES AND PRACTICES
                                        
U. S. Government Securities

     Each Fund may invest in U.S. Government Securities.  Some U.S. Government
Securities (such as Treasury bills, notes and bonds, which differ only in their
interest rates, maturities and times of issuance) are supported by the full
faith and credit of the United States.  Others, such as obligations issued or
guaranteed by U.S. government agencies, instrumentalities or sponsored
enterprises, are supported either by (a) the right of the issuer to borrow from
the U.S. Treasury (such as securities of the Student Loan Marketing
Association), (b) the discretionary authority of the U.S. government to purchase
certain obligations of the issuer (such as securities of Federal National
Mortgage Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation
("Freddie Mac")) or (c) only the credit of the issuer (such as securities of the
Financing Corporation).  The U.S. government is under no legal obligation, in
general,  to purchase the obligations of its agencies, instrumentalities or
sponsored enterprises.  No assurance can be given that the U.S. government will
provide financial support to the U.S. government agencies, instrumentalities or
sponsored enterprises in the future.

     U.S. Government Securities include (to the extent consistent with the
Investment Company Act of 1940, as amended (the "Act")) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, or its agencies, 

                                      B-10
<PAGE>
 
instrumentalities or sponsored enterprises. U.S. Government Securities also
include (to the extent consistent with the Act) participations in loans made to
foreign governments or their agencies that are guaranteed as to principal and
interest by the U.S. government or its agencies, instrumentalities or sponsored
enterprises. The secondary market for certain of these participations is
extremely limited. In the absence of a suitable secondary market, such
participations are regarded as illiquid.

     Each Fund may also purchase U.S. Government Securities in private
placements and may invest in separately traded principal and interest components
of securities guaranteed or issued by the U.S. Treasury that are traded
independently under the separate trading of registered interest and principal of
securities program ("STRIPS").

Custodial Receipts

     Each Fund may invest in custodial receipts in respect of securities issued
or guaranteed as to principal and interest by the U.S. government, its agencies
instrumentalities, political subdivisions or authorities.  Such custodial
receipts evidence ownership of future interest payments, principal payments or
both on certain notes or bonds issued or guaranteed as to principal and interest
by the U.S. government, its agencies, instrumentalities, political subdivisions
or authorities.  These custodial receipts are known by various names, including
"Treasury Receipts," "Treasury Investors Growth Receipts" ("TIGRs") and
"Certificates of Accrual on Treasury Securities" ("CATs"). For certain
securities law purposes, custodial receipts are not considered U.S. Government
Securities.

Mortgage Loans and Mortgage-Backed Securities

     Adjustable Rate, Short Duration Government, Government Income, Core Fixed
Income, Global Income and High Yield Funds (collectively, the "Taxable Funds")
may each invest in mortgage loans and mortgage pass-through securities and other
securities representing an interest in or collateralized by adjustable and
fixed-rate mortgage loans ("Mortgage-Backed Securities").

     Mortgage-Backed Securities (including CMOs, REMICs and SMBS described
below) are subject to both call risk and extension risk.  Because of these
risks, these securities can have significantly greater price and yield
volatility than with traditional fixed-income securities.

     General Characteristics.  Each mortgage pool underlying Mortgage-Backed
     -----------------------                                                
Securities consists of mortgage loans evidenced by promissory notes secured by
first mortgages or first deeds of trust or other similar security instruments
creating a first lien on owner occupied and non-owner occupied one-unit to four-
unit residential properties, multi-family (i.e., five or more) properties,
agriculture properties, commercial properties and mixed use properties (the
"Mortgaged Properties").  The Mortgaged Properties may consist of detached
individual dwelling units, multi-family dwelling units, individual condominiums,
townhouses, duplexes, triplexes, fourplexes, row houses, individual units in
planned unit developments and other attached dwelling units.  The Mortgaged
Properties may also include residential investment properties and second homes.

     The investment characteristics of adjustable and fixed rate Mortgage-Backed
Securities differ from those of traditional fixed-income securities.  The major
differences include the payment of interest and principal on Mortgage-Backed
Securities on a more frequent (usually monthly) schedule, and the possibility
that principal may be prepaid at any time due to prepayments on the underlying
mortgage loans or other assets.  These differences can result in significantly
greater price 

                                      B-11
<PAGE>
 
and yield volatility than is the case with traditional fixed-income securities.
As a result, if a Fund purchases Mortgaged-Backed Securities at a premium, a
faster than expected prepayment rate will reduce both the market value and the
yield to maturity from those which were anticipated. A prepayment rate that is
slower than expected will have the opposite effect of increasing yield to
maturity and market value. Conversely, if a Fund purchases Mortgage-Backed
Securities at a discount, faster than expected prepayments will increase, while
slower than expected prepayments will reduce yield to maturity and market
values. To the extent that a Fund invests in Mortgage-Backed Securities, its
Investment Adviser may seek to manage these potential risks by investing in a
variety of Mortgage-Backed Securities and by using certain hedging techniques.

     Adjustable Rate Mortgage Loans ("ARMs").  ARMs generally provide for a
     ---------------------------------------                               
fixed initial mortgage interest rate for a specified period of time.
Thereafter, the interest rates (the "Mortgage Interest Rates") may be subject to
periodic adjustment based on changes in the applicable index rate (the "Index
Rate").  The adjusted rate would be equal to the Index Rate plus a fixed
percentage spread over the Index Rate established for each ARM at the time of
its origination.  ARMs allow a Fund to participate in increases in interest
rates through periodic increases in the securities coupon rates.  During periods
of declining interest rates, coupon rates may readjust downward resulting in
lower yields to a Fund.

     Adjustable interest rates can cause payment increases that some mortgagors
may find difficult to make.  However, certain ARMs may provide that the Mortgage
Interest Rate may not be adjusted to a rate above an applicable lifetime maximum
rate or below an applicable lifetime minimum rate for such ARM.  Certain ARMs
may also be subject to limitations on the maximum amount by which the Mortgage
Interest Rate may adjust for any single adjustment period (the "Maximum
Adjustment").  Other ARMs ("Negatively Amortizing ARMs") may provide instead or
as well for limitations on changes in the monthly payment on such ARMs.
Limitations on monthly payments can result in monthly payments which are greater
or less than the amount necessary to amortize a Negatively Amortizing ARM by its
maturity at the Mortgage Interest Rate in effect in any particular month.  In
the event that a monthly payment is not sufficient to pay the interest accruing
on a Negatively Amortizing ARM, any such excess interest is added to the
principal balance of the loan, causing negative amortization, and will be repaid
through future monthly payments.  It may take borrowers under Negatively
Amortizing ARMs longer periods of time to build up equity and may increase the
likelihood of default by such borrowers.  In the event that a monthly payment
exceeds the sum of the interest accrued at the applicable Mortgage Interest Rate
and the principal payment which would have been necessary to amortize the
outstanding principal balance over the remaining term of the loan, the excess
(or "accelerated amortization") further reduces the principal balance of the
ARM.  Negatively Amortizing ARMs do not provide for the extension of their
original maturity to accommodate changes in  their Mortgage Interest Rate.  As a
result, unless there is a  periodic recalculation of the payment amount (which
there generally is), the final payment may be substantially larger than the
other payments.  These limitations on periodic increases in interest rates and
on changes in monthly payments protect borrowers from unlimited interest rate
and payment increases.

     ARMs also have the risk of prepayments.  The rate of principal prepayments
with respect to ARMs has fluctuated in recent years.  The value of Mortgage
Backed Securities that are structured as pass through mortgage securities that
are collateralized by ARMs are less likely to rise during 

                                      B-12
<PAGE>
 
periods of declining interest rates to the same extent as fixed-rate securities.
Accordingly, ARMs may be subject to a greater rate of principal repayments in a
declining interest rate environment resulting in lower yields to a Fund. For
example, if prevailing interest rates fall significantly, ARMs could be subject
to higher prepayment rates (than if prevailing interest rates remain constant or
increase) because the availability of low fixed-rate mortgages may encourage
mortgagors to refinance their ARMs to "lock-in" a fixed-rate mortgage. On the
other hand, during periods of rising interest rates, the value of ARMs will lag
behind changes in the market rate. ARMs are also typically subject to maximum
increases and decreases in the interest rate adjustment which can be made on any
one adjustment date, in any one year, or during the life of the security. In the
event of dramatic increases or decreases in prevailing market interest rates,
the value of a Fund's investment in ARMs may fluctuate more substantially since
these limits may prevent the security from fully adjusting its interest rate to
the prevailing market rates. As with fixed-rate mortgages, ARM prepayment rates
vary in both stable and changing interest rate environments.

     There are two main categories of indices which provide the basis for rate
adjustments on ARMs:  those based on U.S. Treasury securities and those derived
from a calculated measure, such as a cost of funds index or a moving average of
mortgage rates. Commonly utilized indices include the one-year, three-year and
five-year constant maturity Treasury rates, the three-month Treasury bill rate,
the 180-day Treasury bill rate, rates on longer-term Treasury securities, the
11th District Federal Home Loan Bank Cost of Funds, the National Median Cost of
Funds, the one-month, three-month, six-month or one-year London Interbank
Offered Rate, the prime rate of a specific bank or commercial paper rates. Some
indices, such as the one-year constant maturity Treasury rate, closely mirror
changes in market interest rate levels.  Others, such as the 11th District
Federal Home Loan Bank Cost of Funds index, tend to lag behind changes in market
rate levels and tend to be somewhat less volatile.  The degree of volatility in
the market value of each Taxable Fund's portfolio and, therefore, in the net
asset value of each Taxable Fund's shares will be a function of the length of
the interest rate reset periods and the degree of volatility in the applicable
indices.

     Fixed-Rate Mortgage Loans.  Generally, fixed-rate mortgage loans included
     -------------------------                                                
in a mortgage pool (the "Fixed-Rate Mortgage Loans") will bear simple interest
at fixed annual rates and have original terms to maturity ranging from 5 to 40
years.  Fixed-Rate Mortgage Loans generally provide for monthly payments of
principal and interest in substantially equal installments for the term of the
mortgage note in sufficient amounts to fully amortize principal by maturity,
although certain Fixed-Rate Mortgage Loans provide for a large final "balloon"
payment upon maturity.

     Legal Considerations of Mortgage Loans.  The following is a discussion of
     --------------------------------------                                   
certain legal and regulatory aspects of the mortgage loans in which the Taxable
Funds may invest.  These regulations may impair the ability of a mortgage lender
to enforce its rights under the mortgage documents. These regulations may
adversely affect the Funds' investments in Mortgage-Backed Securities (including
those issued or guaranteed by the U.S. government, its agencies or
instrumentalities) by delaying the Funds' receipt of payments derived from
principal or interest on mortgage loans affected by such regulations.

1.   Foreclosure.  A foreclosure of a defaulted mortgage loan may be delayed due
     -----------                                                                
     to compliance with statutory notice or service of process provisions,
     difficulties in locating necessary parties or legal challenges to the
     mortgagee's right to foreclose.  Depending upon market 

                                      B-13
<PAGE>
 
     conditions, the ultimate proceeds of the sale of foreclosed property may
     not equal the amounts owed on the Mortgage-Backed Securities.
 
     Furthermore, courts in some cases have imposed general equitable principles
     upon foreclosure generally designed to relieve the borrower from the legal
     effect of default and have required lenders to undertake affirmative and
     expensive actions to determine the causes for the default and the
     likelihood of loan reinstatement.

2.   Rights of Redemption.  In some states, after foreclosure of a mortgage
     --------------------                                                  
     loan, the borrower and foreclosed junior lienors are given a statutory
     period in which to redeem the property, which right may diminish the
     mortgagee's ability to sell the property.

3.   Legislative Limitations.  In addition to anti-deficiency and related
     -----------------------                                             
     legislation, numerous other federal and state statutory provisions,
     including the federal bankruptcy laws and state laws affording relief to
     debtors, may interfere with or affect the ability of a secured mortgage
     lender to enforce its security interest.  For example, a bankruptcy court
     may grant the debtor a reasonable time to cure a default on a mortgage
     loan, including a payment default.  The court in certain instances may also
     reduce the monthly payments due under such mortgage loan, change the rate
     of interest, reduce the principal balance of the loan to the then-current
     appraised value of the related mortgaged property, alter the mortgage loan
     repayment schedule and grant priority of certain liens over the lien of the
     mortgage loan.  If a court relieves a borrower's obligation to repay
     amounts otherwise due on a mortgage loan, the mortgage loan servicer will
     not be required to advance such amounts, and any loss may be borne by the
     holders of securities backed by such  loans.  In addition, numerous federal
     and state consumer protection laws impose penalties for failure to comply
     with specific requirements in connection with origination and servicing of
     mortgage loans.
 
4.   "Due-on-Sale" Provisions.  Fixed-rate mortgage loans may contain a so-
     ------------------------                                             
     called "due-on-sale" clause permitting acceleration of the maturity of the
     mortgage loan if the borrower transfers the property.  The Garn-St. Germain
     Depository Institutions Act of 1982 sets forth nine specific instances in
     which no mortgage lender covered by that Act may exercise a "due-on-sale"
     clause upon a transfer of property. The inability to enforce a "due-on-
     sale" clause or the lack of such a clause in mortgage loan documents may
     result in a mortgage loan being assumed by a purchaser of the property that
     bears an interest rate below the current market rate.

5.   Usury Laws.  Some states prohibit charging interest on mortgage loans in
     ----------                                                              
     excess of statutory limits.  If such limits are exceeded, substantial
     penalties may be incurred and, in some cases, enforceability of the
     obligation to pay principal and interest may be affected.

     Government Guaranteed Mortgage-Backed Securities.  There are several types
     ------------------------------------------------                          
of guaranteed Mortgage-Backed Securities currently available, including
guaranteed mortgage pass-through certificates and multiple class securities,
which include guaranteed Real Estate Mortgage Investment Conduit Certificates
("REMIC Certificates"), other collateralized mortgage obligations and stripped
Mortgage-Backed Securities.  The Taxable Funds are permitted to invest in other
types of Mortgage-Backed Securities that may be available in the future to the
extent consistent with their respective investment policies and objectives.

Guaranteed Mortgage Pass-Through Securities

     Ginnie Mae Certificates.  Ginnie Mae is a wholly-owned corporate
     -----------------------                                         
instrumentality of the United States.  Ginnie Mae is authorized to guarantee the
timely payment of the principal of and interest on certificates that are based
on and backed by a pool of mortgage loans insured by the Federal Housing
Administration ("FHA Loans"), or guaranteed by the Veterans Administration ("VA
Loans"), or by pools of other eligible mortgage loans.  In order to meet its
obligations under any guarantee, Ginnie Mae is authorized to borrow from the
U.S. Treasury in an unlimited amount.

     Fannie Mae Certificates.  Fannie Mae is a stockholder-owned corporation
     -----------------------                                                
chartered under an act of the U.S. Congress. Each Fannie Mae Certificate is
issued and guaranteed by Fannie Mae and represents an undivided interest in a
pool of mortgage loans (a "Pool") formed by Fannie Mae.  Each Pool consists of
residential mortgage loans ("Mortgage Loans") either previously owned by Fannie
Mae or purchased by it in connection with the formation of the Pool.  The
Mortgage Loans may be either conventional Mortgage Loans (i.e., not insured or
guaranteed by any U.S. government agency) or Mortgage Loans that are either
insured by the FHA or guaranteed by the VA. However, the Mortgage Loans in
Fannie Mae Pools are primarily conventional Mortgage Loans.  The lenders
originating and servicing the Mortgage Loans are subject to certain eligibility
requirements established by Fannie Mae.

     Fannie Mae has certain contractual responsibilities.  With respect to each
Pool, Fannie Mae is obligated to distribute scheduled monthly installments of
principal and interest after Fannie Mae's servicing and guaranty fee, whether or
not received, to Certificate holders.  Fannie Mae also is obligated to
distribute to holders of Certificates an amount equal to the full principal
balance of any foreclosed Mortgage Loan, whether or not such principal balance
is actually recovered.  The obligations of Fannie Mae under its guaranty of the
Fannie Mae Certificates are obligations solely of Fannie Mae.

     Freddie Mac Certificates.  Freddie Mac is a publicly held U.S. government
     ------------------------                                                 
sponsored enterprise.  The principal activity of Freddie Mac currently is the
purchase of first lien, conventional, residential mortgage loans and
participation interests in such mortgage loans and their resale in the form of
mortgage securities, primarily Freddie Mac Certificates.  A Freddie Mac
Certificate represents a pro rata interest in a group of mortgage loans or
participation in mortgage loans (a "Freddie Mac Certificate group") purchased by
Freddie Mac.

     Freddie Mac guarantees to each registered holder of a Freddie Mac
Certificate the timely payment of interest at the rate provided for by such
Freddie Mac Certificate (whether or not received on the underlying loans).
Freddie Mac also guarantees to each registered Certificate holder ultimate
collection of all principal of the related mortgage loans, without any offset or
deduction, but does not, generally, guarantee the timely payment of scheduled
principal.  The obligations of Freddie Mac under its guaranty of Freddie Mac
Certificates are obligations solely of Freddie Mac.

     The mortgage loans underlying the Freddie Mac and Fannie Mae Certificates
consist of adjustable rate or fixed-rate mortgage loans with original terms to
maturity of between five and 

                                      B-15
<PAGE>
 
thirty years. Substantially all of these mortgage loans are secured by first
liens on one-to-four-family residential properties or multi-family projects.
Each mortgage loan must meet the applicable standards set forth in the law
creating Freddie Mac or Fannie Mae. A Freddie Mac Certificate group may include
whole loans, participation interests in whole loans, undivided interests in
whole loans and participations comprising another Freddie Mac Certificate group.

     Conventional Mortgage Loans.  The conventional mortgage loans underlying
     ---------------------------                                             
the Freddie Mac and Fannie Mae Certificates consist of adjustable rate or fixed-
rate mortgage loans with original terms to maturity of between five and thirty
years.  Substantially all of these mortgage loans are secured by first liens on
one- to four-family residential properties or multi-family projects.  Each
mortgage loan must meet the applicable standards set forth in the law creating
Freddie Mac or Fannie Mae.  A Freddie Mac Certificate group may include whole
loans, participation interests in whole loans, undivided interests in whole
loans and participations comprising another Freddie Mac Certificate group.

     Mortgage Pass-Through Securities.  The Taxable Funds may invest in both
     --------------------------------                                       
government guaranteed and privately issued mortgage pass-through securities
("Mortgage Pass-Throughs"), that are fixed or adjustable rate Mortgage-Backed
Securities which provide for monthly payments that are a "pass-through" of the
monthly interest and principal payments (including any prepayments) made by the
individual borrowers on the pooled mortgage loans, net of any fees or other
amounts paid to any guarantor, administrator and/or servicer of the underlying
mortgage loans.

     The following discussion describes only a few of the wide variety of
structures of Mortgage Pass-Throughs that are available or may be issued.

     Description of Certificates.  Mortgage Pass-Throughs may be issued in one
     ---------------------------                                              
or more classes of senior certificates and one or more classes of subordinate
certificates.  Each such class may bear a different pass-through rate.
Generally, each certificate will evidence the specified interest of the holder
thereof in the payments of principal or interest or both in respect of the
mortgage pool comprising part of the trust fund for such certificates.

     Any class of certificates may also be divided into subclasses entitled to
varying amounts of principal and interest.  If a REMIC election has been made,
certificates of such subclasses may be entitled to payments on the basis of a
stated principal balance and stated interest rate, and payments among different
subclasses may be made on a sequential, concurrent, pro rata or disproportionate
                                                    --- ----                    
basis, or any combination thereof.  The stated interest rate on any such
subclass of certificates may be a fixed rate or one which varies in direct or
inverse relationship to an objective interest index.

     Generally, each registered holder of a certificate will be entitled to
receive its pro rata share of monthly distributions of all or a portion of
            --- ----                                                      
principal of the underlying mortgage loans or of interest on the principal
balances thereof, which accrues at the applicable mortgage pass-through rate, or
both.  The difference between the mortgage interest rate and the related
mortgage pass-through rate (less the amount, if any, of retained yield) with
respect to each mortgage loan will generally be paid to the servicer as a
servicing fee.  Since certain adjustable rate mortgage loans included in a
mortgage pool may provide for deferred interest (i.e., negative amortization),
the 

                                      B-16
<PAGE>
 
amount of interest actually paid by a mortgagor in any month may be less than
the amount of interest accrued on the outstanding principal balance of the
related mortgage loan during the relevant period at the applicable mortgage
interest rate. In such event, the amount of interest that is treated as deferred
interest will be added to the principal balance of the related mortgage loan and
will be distributed pro rata to certificate-holders as principal of such
                    --- ----
mortgage loan when paid by the mortgagor in subsequent monthly payments or at
maturity.

     Multiple Class Mortgage-Backed Securities and Collateralized Mortgage
     ---------------------------------------------------------------------
Obligations.  Each Taxable Fund may invest in multiple class securities
- -----------                                                            
including collateralized mortgage obligations ("CMOs") and REMIC Certificates.
These securities may be issued by U.S. government agencies and instrumentalities
such as Fannie Mae or sponsored enterprises such as Freddie Mac or, in the case
of Core Fixed Income, Global and Government Income Funds, by trusts formed by
private originators of, or investors in, mortgage loans, including savings and
loan associations, mortgage bankers, commercial banks, insurance companies,
investment banks and special purpose subsidiaries of the foregoing.  In general,
CMOs are debt obligations of a legal entity that are collateralized by, and
multiple class Mortgage-Backed Securities represent direct ownership interests
in, a pool of mortgage loans or Mortgage-Backed Securities the payments on which
are used to make payments on the CMOs or multiple class Mortgage-Backed
Securities.

     Fannie Mae REMIC Certificates are issued and guaranteed as to timely
distribution of principal and interest by Fannie Mae.  In addition, Fannie Mae
will be obligated to distribute the principal balance of each class of REMIC
Certificates in full, whether or not sufficient funds are otherwise available.

     Freddie Mac guarantees the timely payment of interest on Freddie Mac REMIC
Certificates and also guarantees the payment of principal as payments are
required to be made on the underlying mortgage participation certificates
("PCs").  PCs represent undivided interests in specified level payment,
residential mortgages or participations therein purchased by Freddie Mac and
placed in a PC pool.  With respect to principal payments on PCs, Freddie Mac
generally guarantees ultimate collection of all principal of the related
mortgage loans without offset or deduction.  Freddie Mac also guarantees timely
payment of principal of certain PCs.

     CMOs and guaranteed REMIC Certificates issued by Fannie Mae and Freddie Mac
are types of multiple class Mortgage-Backed Securities.  Investors may purchase
beneficial interests in REMICs, which are known as "regular" interests or
"residual" interests. The Funds do not intend to purchase residual interests in
REMICs. The REMIC Certificates represent beneficial ownership interests in a
REMIC trust, generally consisting of mortgage loans or Fannie Mae, Freddie Mac
or Ginnie Mae guaranteed Mortgage-Backed Securities (the "Mortgage Assets").
The obligations of Fannie Mae or Freddie Mac under their respective guaranty of
the REMIC Certificates are obligations solely of Fannie Mae or Freddie Mac,
respectively.

     CMOs and REMIC Certificates are issued in multiple classes. Each class of
CMOs or REMIC Certificates, often referred to as a "tranche," is issued at a
specific adjustable or fixed interest rate and must be fully retired no later
than its final distribution date.  Principal prepayments on the Mortgage Loans
or the Mortgage Assets underlying the CMOs or REMIC Certificates may 

                                      B-17
<PAGE>
 
cause some or all of the classes of CMOs or REMIC Certificates to be retired
substantially earlier than their final distribution dates. Generally, interest
is paid or accrues on all classes of CMOs or REMIC Certificates on a monthly
basis.

     The principal of and interest on the Mortgage Assets may be allocated among
the several classes of CMOs or REMIC Certificates in various ways.  In certain
structures (known as "sequential pay" CMOs or REMIC Certificates), payments of
principal, including any principal prepayments, on the Mortgage Assets generally
are applied to the classes of CMOs or REMIC Certificates in the order of their
respective final distribution dates.  Thus, no payment of principal will be made
on any class of sequential pay CMOs or REMIC Certificates until all other
classes having an earlier final distribution date have been paid in full.

     Additional structures of CMOs and REMIC Certificates include, among others,
"parallel pay" CMOs and REMIC Certificates. Parallel pay CMOs or REMIC
Certificates are those which are structured to apply principal payments and
prepayments of the Mortgage Assets to two or more classes concurrently on a
proportionate or disproportionate basis.  These simultaneous payments are taken
into account in calculating the final distribution date of each class.

     A wide variety of REMIC Certificates may be issued in parallel pay or
sequential pay structures.  These securities include accrual certificates (also
known as "Z-Bonds"), which only accrue interest at a specified rate until all
other certificates having an earlier final distribution date have been retired
and are converted thereafter to an interest-paying security, and planned
amortization class ("PAC") certificates, which are parallel pay REMIC
Certificates that generally require that specified amounts of principal be
applied on each payment date to one or more classes or REMIC Certificates (the
"PAC Certificates"), even though all other principal payments and  prepayments
of the Mortgage Assets are then required to be applied to one or more other
classes of the Certificates.  The scheduled principal payments for the PAC
Certificates generally have the highest priority on each payment date after
interest due has been paid to all classes entitled to receive interest
currently. Shortfalls, if any, are added to the amount payable on the  next
payment date.  The PAC Certificate payment schedule is taken into account in
calculating the final distribution date of each class of PAC.  In order to
create PAC tranches, one or more tranches generally must be created that absorb
most of the volatility in the underlying Mortgage Assets. These tranches tend to
have market prices and yields that are much more volatile than other PAC
classes.

     Stripped Mortgage-Backed Securities.  The Taxable Funds may invest in
     -----------------------------------                                  
Stripped Mortgage-Backed Securities ("SMBS"), which are derivative multiclass
mortgage securities, issued or guaranteed by the U.S. government, its agencies
or instrumentalities.  Core Fixed Income, Government Income Fund and Global
Income Fund may also invest in privately-issued SMBS.  Although the market for
such securities is increasingly liquid, privately-issued SMBS may not be readily
marketable and will be considered illiquid for purposes of each Fund's
limitation on investments in illiquid securities. The Investment Adviser may
determine that SMBS which are U.S. Government Securities are liquid for purposes
of each Fund's limitation on investments in illiquid securities.  The market
value of the class consisting entirely of principal payments generally is
unusually volatile in response to changes in interest rates.  The yields on a
class of SMBS that 

                                      B-18
<PAGE>
 
receives all or most of the interest from Mortgage Assets are generally higher
than prevailing market yields on other Mortgage-Backed Securities because their
cash flow patterns are more volatile and there is a greater risk that the
initial investment will not be fully recouped. A Fund's investment in SMBS may
require the Fund to sell certain of its portfolio securities to generate
sufficient cash to satisfy certain income distribution requirements.

Privately Issued Mortgage-Backed Securities

     Privately issued Mortgage-Backed Securities are generally backed by pools
of conventional (i.e., non-government guaranteed or insured) mortgage loans.

     Ratings.  The ratings assigned by a rating organization to Mortgage Pass-
     -------                                                                 
Throughs address the likelihood of the receipt of all distributions on the
underlying mortgage loans by the related certificate-holders under the
agreements pursuant to which such certificates are issued.  A rating
organization's ratings take into consideration the credit quality of the related
mortgage pool, including any credit support providers, structural and legal
aspects associated with such certificates, and the extent to which the payment
stream on such mortgage pool is adequate to make payments required by such
certificates.  A rating organization's ratings on such certificates do not,
however, constitute a statement regarding frequency of prepayments on the
related mortgage loans.  In addition, the rating assigned by a rating
organization to a certificate does not address the remote possibility that, in
the event of the insolvency of the issuer of certificates where a subordinated
interest was retained, the issuance and sale of the senior certificates may be
recharacterized as a financing and, as a result of such recharacterization,
payments on such certificates may be affected.

     Credit Enhancement.  Credit support falls generally into two categories:
     ------------------                                                       
(i) liquidity protection and (ii) protection against losses resulting from
default by an obligor on the underlying assets.  Liquidity protection refers to
the provision of advances, generally by the entity administering the pools of
mortgages, the provision of a reserve fund, or a combination thereof, to ensure,
subject to certain limitations, that scheduled payments on the underlying pool
are made in a timely fashion.  Protection against losses resulting from default
ensures ultimate payment of the obligations on at least a portion of the assets
in the pool.  Such credit support can be provided by, among other things,
payment guarantees, letters of credit, pool insurance, subordination, or any
combination thereof.

     Subordination; Shifting of Interest; Reserve Fund.  In order to achieve
     -------------------------------------------------                      
ratings on one or more classes of Mortgage Pass-Throughs, one or more classes of
certificates may be subordinate certificates which provide that the rights of
the subordinate certificate-holders to receive any or a specified portion of
distributions with respect to the underlying mortgage loans may be subordinated
to the rights of the senior certificate-holders.  If so structured, the
subordination feature may be enhanced by distributing to the senior certificate-
holders on certain distribution dates, as payment of principal, a specified
percentage (which generally declines over time) of all principal payments
received during the preceding prepayment period ("shifting interest credit
enhancement").  This will have the effect of accelerating the amortization of
the senior certificates while increasing the interest in the trust fund
evidenced by the subordinate certificates.  Increasing the interest of the
subordinate certificates relative to that of the senior certificates is intended
to preserve the availability of the 

                                      B-19
<PAGE>
 
subordination provided by the subordinate certificates. In addition, because the
senior certificate-holders in a shifting interest credit enhancement structure
are entitled to receive a percentage of principal prepayments which is greater
than their proportionate interest in the trust fund, the rate of principal
prepayments on the mortgage loans will have an even greater effect on the rate
of principal payments and the amount of interest payments on, and the yield to
maturity of, the senior certificates.

     In addition to providing for a preferential right of the senior
certificate-holders to receive current distributions from the mortgage pool, a
reserve fund may be established relating to such certificates (the "Reserve
Fund").  The Reserve Fund may be created with an initial cash deposit by the
originator or servicer and augmented by the retention of distributions otherwise
available to the subordinate certificate-holders or by excess servicing fees
until the Reserve Fund reaches a specified amount.

     The subordination feature, and any Reserve Fund, are intended to enhance
the likelihood of timely receipt by senior certificate-holders of the full
amount of scheduled monthly payments of principal and interest due to them and
will protect the senior certificate-holders against certain losses; however, in
certain circumstances the Reserve Fund could be depleted and temporary
shortfalls could result.  In the event that the Reserve Fund is depleted before
the subordinated amount is reduced to zero, senior certificate-holders will
nevertheless have a preferential right to receive current distributions from the
mortgage pool to the extent of the then outstanding subordinated amount.  Unless
otherwise specified, until the subordinated amount is reduced to zero, on any
distribution date any amount otherwise distributable to the subordinate
certificates or, to the extent specified, in the Reserve Fund will generally be
used to offset the amount of any losses realized with respect to the mortgage
loans ("Realized Losses").  Realized Losses remaining after application of such
amounts will generally be applied to reduce the ownership interest of the
subordinate certificates in the mortgage pool.  If the subordinated amount has
been reduced to zero, Realized Losses generally will be allocated pro rata among
                                                                  --- ----      
all certificate-holders in proportion to their respective outstanding interests
in the mortgage pool.

     Alternative Credit Enhancement.  As an alternative, or in addition to the
     ------------------------------                                           
credit enhancement afforded by subordination, credit enhancement for Mortgage
Pass-Throughs may be provided by mortgage insurance, hazard insurance, by the
deposit of cash, certificates of deposit, letters of credit, a limited guaranty
or by such other methods as are acceptable to a rating agency.  In certain
circumstances, such as where credit enhancement is provided by guarantees or a
letter of credit, the security is subject to credit risk because of its exposure
to an external credit enhancement provider.

     Voluntary Advances.  Generally, in the event of delinquencies in payments
     ------------------                                                       
on the mortgage loans underlying the Mortgage Pass-Throughs, the servicer agrees
to make advances of cash for the benefit of certificate-holders, but only to the
extent that it determines such voluntary advances will be recoverable from
future payments and collections on the mortgage loans or otherwise.

                                      B-20
<PAGE>
 
     Optional Termination.  Generally, the servicer may, at its option with
     --------------------                                                  
respect to any certificates, repurchase all of the underlying mortgage loans
remaining outstanding at such time as the aggregate outstanding principal
balance of such mortgage loans is less than a specified percentage (generally 5-
10%) of the aggregate outstanding principal balance of the mortgage loans as of
the cut-off date specified with respect to such series.

Asset-Backed Securities

     Asset-backed securities represent participation in, or are secured by and
payable from, assets such as motor vehicle installment sales, installment loan
contracts, leases of various types of real and personal property, receivables
from revolving credit (credit card) agreements and other categories of
receivables. Such assets are securitized through the use of trusts and special
purpose corporations. Payments or distributions of principal and interest may be
guaranteed up to certain amounts and for a certain time period by a letter of
credit or a pool insurance policy issued by a financial institution unaffiliated
with the trust or corporation, or other credit enhancements may be present.

     Government Income, Core Fixed Income, Global Income and High Yield Funds
may invest in asset-backed securities.  Such securities are often subject to
more rapid repayment than their stated maturity date would indicate as a result
of the pass-through of prepayments of principal on the underlying loans. During
periods of declining interest rates, prepayment of loans underlying asset-backed
securities can be expected to accelerate. Accordingly, a Fund's ability to
maintain positions in such securities will be affected by reductions in the
principal amount of such securities resulting from prepayments, and its ability
to reinvest the returns of principal at comparable yields is subject to
generally prevailing interest rates at that time.  To the extent that a Fund
invests in asset-backed securities, the values of such Fund's portfolio
securities will vary with changes in market interest rates generally and the
differentials in yields among various kinds of asset-backed securities.

     Asset-backed securities present certain additional risks that are not
presented by Mortgage-Backed Securities because asset-backed securities
generally do not have the benefit of a security interest in collateral that is
comparable to Mortgage Assets. Credit card receivables are generally unsecured
and the debtors on such receivables are entitled to the protection of a number
of state and federal consumer credit laws, many of which give such debtors the
right to set-off certain amounts owed on the credit cards, thereby reducing the
balance due.  Automobile receivables generally are secured, but by automobiles
rather than residential real property.  Most issuers of automobile receivables
permit the loan servicers to retain possession of the underlying obligations.
If the servicer were to sell these obligations to another party, there is a risk
that the purchaser would acquire an interest superior to that of the holders of
the asset-backed securities. In addition, because of the large number of
vehicles involved in a typical issuance and technical requirements under state
laws, the trustee for the holders of the automobile receivables may not have a
proper security interest in the underlying automobiles. Therefore, there is the
possibility that, in some cases, recoveries on repossessed collateral may not be
available to support payments on these securities.

                                      B-21

Loan Participations

     The High Yield Fund may invest in loan participations.  Such loans must be
to issuers in whose obligations the High Yield Fund may invest.  A loan
participation is an interest in a loan to a U.S. or foreign company or other
borrower which is administered and sold by a financial intermediary.  In a
typical corporate loan syndication, a number of lenders, usually banks (co-
lenders), lend a corporate borrower a specified sum pursuant to the terms and
conditions of a loan agreement.  One of the co-lenders usually agrees to act as
the agent bank with respect to the loan.

     Participation interests acquired by the High Yield Fund may take the form
of a direct or co-lending relationship with the corporate borrower, an
assignment of an interest in the loan by a co-lender or another participant, or
a participation in the seller's share of the loan.  When the High Yield Fund
acts as co-lender in connection with a participation interest or when the High
Yield Fund acquires certain participation interests, the High Yield Fund will
have direct recourse against the borrower if the borrower fails to pay scheduled
principal and interest.  In cases where the High Yield Fund lacks direct
recourse, it will look to the agent bank to enforce appropriate credit remedies
against the borrower.  In these cases, the High Yield Fund may be subject to
delays, expenses and risks that are greater than those that would have been
involved if the Fund had purchased a direct obligation (such as commercial
paper) of such borrower.  For example, in the event of the bankruptcy or
insolvency of the corporate borrower, a loan participation may be subject to
certain defenses by the borrower as a result of improper conduct by the agent
bank. Moreover, under the terms of the loan participation, the High Yield Fund
may be regarded as a creditor of the agent bank (rather than of the underlying
corporate borrower), so that the High Yield Fund may also be subject to the risk
that the agent bank may become insolvent.  The secondary market, if any, for
these loan participations is limited and any loan participations purchased by
the High Yield Fund will be regarded as illiquid.

     For purposes of certain investment limitations pertaining to
diversification of the High Yield Fund's portfolio investments, the issuer of a
loan participation will be the underlying borrower.  However, in cases where the
High Yield Fund does not have recourse directly against the borrower, both the
borrower and each agent bank and co-lender interposed between the High Yield
Fund and the borrower will be deemed issuers of a loan participation.

Zero Coupon, Deferred Interest, Pay-in-Kind and Capital  Appreciation Bonds

     Each Fund may invest in zero coupon bonds, deferred interest and capital
appreciation bonds and pay-in-kind ("PIK") securities. Zero coupon, deferred
interest and capital appreciation bonds are debt securities issued or sold at a
discount from their face value and which do not entitle the holder to any
periodic payment of interest prior to maturity or a specified date.  The
original issue discount varies depending on the time remaining until maturity or
cash payment date, prevailing interest rates, the liquidity of the security and
the perceived credit quality of the issuer.  These securities also may take the
form of debt securities that have been stripped of their unmatured interest
coupons, the coupons themselves or receipts or certificates representing
interests in such stripped debt obligations or coupons.  The market prices of
zero coupon, deferred interest, capital appreciation bonds and PIK securities
generally are more volatile than the market prices of interest 

                                      B-22
<PAGE>
 
bearing securities and are likely to respond to a greater degree to changes in
interest rates than interest bearing securities having similar maturities and
credit quality.

     PIK securities may be debt obligations or preferred shares that provide the
issuer with the option of paying interest or dividends on such obligations in
cash or in the form of additional securities rather than cash. Similar to zero
coupon bonds and deferred interest bonds, PIK securities are designed to give an
issuer flexibility in managing cash flow. PIK securities that are debt
securities can either be senior or subordinated debt and generally trade flat
(i.e., without accrued interest). The trading price of PIK debt securities
generally reflects the market value of the underlying debt plus an amount
representing accrued interest since the last interest payment.

     Zero coupon, deferred interest, capital appreciation and PIK securities
involve the additional risk that, unlike securities that periodically pay
interest to maturity, a Fund will realize no cash until a specified future
payment date unless a portion of such securities is sold and, if the issuer of
such securities defaults, a Fund may obtain no return at all on its investment.
In addition, even though such securities do not provide for the payment of
current interest in cash, the Funds are nonetheless required to accrue income on
such investments for each taxable year and generally are required to distribute
such accrued amounts (net of deductible expenses, if any) to avoid being subject
to tax.  Because no cash is generally received at the time of the accrual, a
Fund may be required to liquidate other portfolio securities to obtain
sufficient cash to satisfy federal tax distribution requirements applicable to
the Fund.  A portion of the discount with respect to stripped tax-exempt
securities or their coupons may be taxable.  See "Taxation."

Variable and Floating Rate Securities

     The interest rates payable on certain securities in which each Fund may
invest are not fixed and may fluctuate based upon changes in market rates.  A
variable rate obligation has an interest rate which is adjusted at predesignated
periods in response to changes in the market rate of interest on which the
interest rate is based. Variable and floating rate obligations are less
effective than fixed rate instruments at locking in a particular yield.
Nevertheless, such obligations may fluctuate in value in response to interest
rate changes if there is a delay between changes in market interest rates and
the interest reset date for the obligation.

     Each Fund may invest in "leveraged" inverse floating rate debt instruments
("inverse floaters"), including "leveraged inverse floaters."  The interest rate
on inverse floaters resets in the opposite direction from the market rate of
interest to which the inverse floater is indexed.  An inverse floater may be
considered to be leveraged to the extent that its interest rate varies by a
magnitude that exceeds the magnitude of the change in the index rate of
interest.  The higher the degree of leverage of an inverse floater, the greater
the volatility of its market value.  Accordingly, the duration of an inverse
floater may exceed its stated final maturity.  Certain inverse floaters may be
deemed to be illiquid securities for purposes of each Fund's limitation on
illiquid investments.

Preferred Stock, Warrants and Rights

     The High Yield Fund may invest in preferred stock, warrants and rights.
Preferred stocks are securities that represent an ownership interest providing
the holder with claims on the issuer's earnings and assets before common stock
owners but after bond owners.  Unlike debt securities, the obligations of an
issuer of preferred stock, including dividend and other payment obligations, may
not typically be accelerated by the holders of such preferred stock on the
occurrence of an event of default (such as a covenant default or filing of a
bankruptcy petition) or other non-compliance by the issuer with the terms of the
preferred stock.  Often, however, on the occurrence of any such event of default
or non-compliance by the issuer, preferred stockholders will be entitled to gain
representation on the issuer's board of directors or increase their existing
board representation.  In addition, preferred stockholders may be granted voting
rights with respect to certain issues on the occurrence of any event of default.

     Warrants and other rights are options to buy a stated number of shares of
common stock at a specified price at any time during the life of the warrant.
The holders of warrants and rights have no voting rights, receive no dividends
and have no rights with respect to the assets of the issuer.

Corporate Debt Obligations

     Government Income, Core Fixed Income, Global Income and High Yield Funds
may invest in corporate debt obligations, including obligations of industrial,
utility and financial issuers.  Corporate debt obligations include bonds, notes,
debentures and other obligations of corporations to pay interest and repay
principal.  Corporate debt obligations are subject to the risk of an issuer's
inability to meet principal and interest payments on the obligations and may
also be subject to price volatility due to such factors as market interest
rates, market perception of the creditworthiness of the issuer and general
market liquidity.

     Fixed income securities rated BBB or Baa are considered medium-grade
obligations with speculative characteristics, and adverse economic conditions or
changing circumstances may weaken their issuers' capacity to pay interest and
repay principal. Medium to lower rated and comparable non-rated securities tend
to offer higher yields than higher rated securities with the same maturities
because the historical financial condition of the issuers of such securities may
not have been as strong as that of other issuers.  Since medium to lower rated
securities generally involve greater risks of loss of income and principal than
higher rated securities, investors should consider carefully the relative risks
associated with investment in securities which carry medium to lower ratings and
in comparable unrated securities.  In addition to the risk of default, there are
the related costs of recovery on defaulted issues.  The Funds' Investment
Advisers will attempt to reduce these risks through portfolio diversification
and by analysis of each issuer and its ability to make timely payments of income
and principal, as well as broad economic trends and corporate developments.

High Yield Funds may invest in trust preferred securities.  A trust preferred or
capital security is a long dated bond (for example 30 years) with preferred
features.  The preferred features are that payment of interest can be deferred
for a specified period without initiating a default event.  From a 

                                      B-24
<PAGE>
 
bondholder's viewpoint, the securities are senior in claim to standard preferred
but are junior to other bondholders. From the issuer's viewpoint, the securities
are attractive because their interest is deductible for tax purposes like other
types of debt instruments.

     High Yield Securities.  High Yield Fund may invest in bonds rated BB or
     ---------------------                                                  
below by Standard & Poor's or Ba or below by Moody's (or comparable rated and
unrated securities).  These bonds are commonly referred to as "junk bonds" and
are considered speculative.  The ability of their issuers to make principal and
interest payments may be questionable.  In some cases, such bonds may be highly
speculative, have poor prospects for reaching investment grade standing and be
in default.  As a result, investment in such bonds will entail greater risks
than those associated with investment grade bonds (i.e., bonds rated AAA, AA, A
or BBB by Standard and Poor's or Aaa, Aa, A or Baa by Moody's).  Analysis of the
creditworthiness of issuers of high yield securities may be more complex than
for issuers of higher quality debt securities, and the ability of a Fund to
achieve its investment objective may, to the extent of its investments in high
yield securities, be more dependent upon such creditworthiness analysis than
would be the case if the Fund were investing in higher quality securities.  See
Appendix B for a description of the corporate bond and preferred stock ratings
by Standard & Poor's, Moody's, Fitch IBCA, Inc. ("Fitch IBCA") and Duff &
Phelps.

     The amount of high yield, fixed-income securities proliferated in the 1980s
and early 1990s as a result of increased merger and acquisition and leveraged
buyout activity.  Such securities are also issued by less-established
corporations desiring to expand.  Risks associated with acquiring the securities
of such issuers generally are greater than is the case with higher rated
securities because such issuers are often less creditworthy companies or are
highly leveraged and generally less able than more established or less leveraged
entities to make scheduled payments of principal and interest.

     The market values of high yield, fixed-income securities tends to reflect
those individual corporate developments to a greater extent than do those of
higher rated securities, which react primarily to fluctuations in the general
level of interest rates.  Issuers of such high yield securities are often highly
leveraged, and may not be able to make use of more traditional methods of
financing.  Their ability to service debt obligations may be more adversely
affected than issuers of higher rated securities by economic downturns, specific
corporate developments or the issuers' inability to meet specific projected
business forecasts.  These non-investment grade securities also tend to be more
sensitive to economic conditions than higher-rated securities.  Negative
publicity about the junk bond market and investor perceptions regarding lower-
rated securities, whether or not based on fundamental analysis, may depress the
prices for such securities.

     Since investors generally perceive that there are greater risks associated
with non-investment grade securities of the type in which High Yield Fund
invests, the yields and prices of such securities may tend to fluctuate more
than those for higher-rated securities.  In the lower quality segments of the
fixed-income securities market, changes in perceptions of issuers'
creditworthiness tend to occur more frequently and in a more pronounced manner
than do changes in higher quality segments of the fixed-income securities
market, resulting in greater yield and price volatility.

                                      B-25
<PAGE>
 
     Another factor which causes fluctuations in the prices of high yield,
fixed-income securities is the supply and demand for similarly rated securities.
In addition, the prices of fixed-income securities fluctuate in response to the
general level of interest rates.  Fluctuations in the prices of portfolio
securities subsequent to their acquisition will not affect cash income from such
securities but will be reflected in the High Yield Fund's net asset value.

     The risk of loss from default for the holders of high yield, fixed-income
securities is significantly greater than is the case for holders of other debt
securities because such high yield fixed-income securities are generally
unsecured and are often subordinated to the rights of other creditors of the
issuers of such securities.  Investment by the High Yield Fund in already
defaulted securities poses an additional risk of loss should nonpayment of
principal and interest continue in respect of such securities.  Even if such
securities are held to maturity, recovery by the High Yield Fund of its initial
investment and any anticipated income or appreciation is uncertain.  In
addition, the High Yield Fund may incur additional expenses to the extent that
it is required to seek recovery relating to the default in the payment of
principal or interest on such securities or otherwise protect its interests.
The High Yield Fund may be required to liquidate other portfolio securities to
satisfy the High Yield Fund's annual distribution obligations in respect of
accrued interest income on securities which are subsequently written off, even
though the High Yield Fund has not received any cash payments of such interest.

     The secondary market for high yield, fixed-income securities is
concentrated in relatively few markets and is dominated by institutional
investors, including mutual funds, insurance companies and other financial
institutions.  Accordingly, the secondary market for such securities is not as
liquid as and is more volatile than the secondary market for higher-rated
securities.  In addition, the trading volume for high-yield, fixed-income
securities is generally lower than that of higher rated securities and the
secondary market for high yield, fixed-income securities could contract under
adverse market or economic conditions independent of any specific adverse
changes in the condition of a particular issuer.  These factors may have an
adverse effect on the High Yield Fund's ability to dispose of particular
portfolio investments.  Prices realized upon the sale of such lower rated or
unrated securities, under these circumstances, may be less than the prices used
in calculating the High Yield Fund's net asset value.  A less liquid secondary
market also may make it more difficult for the High Yield Fund to obtain precise
valuations of the high yield securities in its portfolio.

     Certain proposed and recently enacted federal laws could adversely affect
the secondary market for high yield securities and the financial condition of
issuers of these securities.  The form of proposed legislation and the
probability of such legislation being enacted is uncertain.

     Non-investment grade or high-yield, fixed-income securities also present
risks based on payment expectations.  High yield, fixed-income securities
frequently contain "call" or buy-back features which permit the issuer to call
or repurchase the security from its holder.  If an issuer exercises such a "call
option" and redeems the security, the High Yield Fund may have to replace such
security with a lower-yielding security, resulting in a decreased return for
investors.  In addition, if the High Yield Fund experiences net redemptions of
its shares, it may be forced to sell 

                                      B-26
<PAGE>
 
its higher-rated securities, resulting in a decline in the overall credit
quality of the High Yield Fund's portfolio and increasing the exposure of the
High Yield Fund to the risks of high yield securities.

     Credit ratings issued by credit rating agencies are designed to evaluate
the safety of principal and interest payments of rated securities.  They do not,
however, evaluate the market value risk of non-investment grade securities and,
therefore, may not fully reflect the true risks of an investment.  In addition,
credit rating agencies may or may not make timely changes in a rating to reflect
changes in the economy or in the conditions of the issuer that affect the market
value of the security.  Consequently, credit ratings are used only as a
preliminary indicator of investment quality.  Investments in non-investment
grade and comparable unrated obligations will be more dependent on the
Investment Adviser's credit analysis than would be the case with investments in
investment-grade debt obligations.  The Investment Adviser employs its own
credit research and analysis, which includes a study of existing debt, capital
structure, ability to service debt and to pay dividends, the issuer's
sensitivity to economic conditions, its operating history and the current trend
of earnings.  The Investment Adviser continually monitors the investments in the
High Yield Fund's portfolio and evaluates whether to dispose of or to retain
non-investment grade and comparable unrated securities whose credit ratings or
credit quality may have changed.

     Because the market for high yield securities is still relatively new and
has not weathered a major economic recession, it is unknown what effects such a
recession might have on such securities.  A widespread economic downturn could
result in increased defaults and losses.


Bank Obligations

     Government Income, Core Fixed Income, Global Income and High Yield Funds
may each invest in obligations issued or guaranteed by U.S. and foreign banks
(Government Income Fund may only invest in U.S. dollar denominated securities).
Bank obligations, including without limitation time deposits, bankers'
acceptances and certificates of deposit, may be general obligations of the
parent bank or may be obligations only of the issuing branch pursuant to the
terms of the specific obligations or government regulation.

     Banks are subject to extensive governmental regulations which may limit
both the amount and types of loans which may be made and interest rates which
may be charged.  Foreign banks are subject to different regulations and are
generally permitted to engage in a wider variety of activities than U.S. banks.
In addition, the profitability of the banking industry is largely dependent upon
the availability and cost of funds for the purpose of financing lending
operations under prevailing money market conditions. General economic conditions
as well as exposure to credit losses arising from possible financial
difficulties of borrowers play an important part in the operations of this
industry.

Municipal Securities

     Municipal Income, Core Fixed Income, High Yield and Short Duration Tax-Free
Funds may invest in Municipal Securities, the interest on which is exempt from
regular federal income tax (i.e., excluded from gross income for federal income
tax purposes but not necessarily exempt from the federal alternative minimum tax
or from the income taxes of any state or local government).  In addition,
Municipal Securities include participation interests in such securities the
interest on which is, in the opinion of bond counsel or counsel selected by the
Investment Adviser, excluded from gross income for federal income tax purposes.
Municipal Income, Core Fixed Income, High Yield and Short Duration Tax-Free
Funds may revise their definition of Municipal Securities in the future to
include other types of securities that currently exist, the interest on which is
or will be, in the opinion of such counsel, excluded from gross income for
federal income tax purposes, provided that investing in such securities is
consistent with each Fund's investment objective and policies.

     Municipal Securities are often issued to obtain funds for various public
purposes including refunding outstanding obligations, obtaining funds for
general operating expenses, and obtaining funds to lend to other public
institutions and facilities.  Municipal Securities also include certain "private
activity bonds" or industrial development bonds, which are issued by or on
behalf of public authorities to provide financing aid to acquire sites or
construct or equip facilities within a municipality for privately or publicly
owned corporations.

     The two principal classifications of Municipal Securities are "general
obligations" and "revenue obligations."  General obligations are secured by the
issuer's pledge of its full faith and credit for the payment of principal and
interest, although the characteristics and enforcement of general obligations
may vary according to the law applicable to the particular issuer.  Revenue
obligations, which include, but are  not limited to, private activity bonds,
resource recovery bonds, certificates of participation and certain municipal
notes, are not backed by the credit and taxing authority of the issuer, and are
payable solely from the revenues derived from a particular facility or class of
facilities or, in some cases, from the proceeds of a special excise or other
specific revenue source.  Nevertheless, the obligations of the issuer of a
revenue obligation may be backed by a letter of credit, guarantee or insurance.
General obligations and revenue obligations may be issued in a variety of forms,
including commercial paper, fixed, variable and floating rate securities, tender
option bonds, auction rate bonds and zero coupon bonds, deferred interest bonds
and capital appreciation bonds.

     In addition to general obligations and revenue obligations, there is a
variety of hybrid and special types of Municipal Securities.  There are also
numerous differences in the security of Municipal Securities both within and
between these two principal classifications.

     For the purpose of applying a Fund's investment restrictions, the
identification of the issuer of a Municipal Security which is not a general
obligation is made by the Investment Adviser based on the characteristics of the
Municipal Security, the most important of which is the source of funds for the
payment of principal and interest on such securities.

                                      B-28
<PAGE>
 
     An entire issue of Municipal Securities may be purchased by one or a small
number of institutional investors such as Short Duration Tax-Free, Municipal
Income, High Yield and Core Fixed Income Funds. Thus, the issue may not be said
to be publicly offered.  Unlike some securities that are not publicly offered, a
secondary market exists for many Municipal Securities that were not publicly
offered initially and such securities may be readily marketable.

     The credit rating assigned to Municipal Securities may reflect the
existence of guarantees, letters of credit or other credit enhancement features
available to the issuers or holders of such Municipal Securities.

     The obligations of the issuer to pay the principal of and interest on a
Municipal Security are subject to the provisions of bankruptcy, insolvency and
other laws affecting the rights and remedies of creditors, such as the Federal
Bankruptcy Act, and laws, if any, that may be enacted by Congress or state
legislatures extending the time for payment of principal or interest or imposing
other constraints upon the enforcement of such obligations.  There is also the
possibility that, as a result of litigation or other conditions, the power or
ability of the issuer to pay when due principal of or interest on a Municipal
Security may be materially affected.

     While the Municipal Income Fund and Short Duration Tax-Free Fund, under
normal market conditions, invest substantially all of their assets in Municipal
Securities, the recognition of certain accrued market discount income (if the
Funds acquire Municipal Securities or other obligations at a market discount),
income from investments other than Municipal Securities and any capital gains
generated from the disposition of investments, will result in taxable income.
In addition to federal income tax, shareholders may be subject to state, local
or foreign taxes on distributions of such income received from the Funds.

High Yield Funds may invest in municipal leases, certificates of participation
and other participation interests. A municipal lease is an obligation in the
form of a lease or installment purchase which is issued by a state or local
government to acquire equipment and facilities.  Income from such obligations is
generally exempt from state and local taxes in the state of issuance.  Municipal
leases frequently involve special risks not normally associated with general
obligations or revenue bonds.  Leases and installment purchase or conditional
sale contracts (which normally provide for title to the leased asset to pass
eventually to the governmental issuer) have evolved as a means for governmental
issuers to acquire property and equipment without meeting the constitutional and
statutory requirements for the issuance of debt.  The debt issuance limitations
are deemed to be inapplicable because of the inclusion in many leases or
contracts of "non-appropriation" clauses that relieve the governmental issuer of
any obligation to make future payments under the lease or contract unless money
is appropriated for such purpose by the appropriate legislative body on a yearly
or other periodic basis.  In addition, such leases or contracts may be subject
to the temporary abatement of payments in the event the issuer is prevented from
maintaining occupancy of the leased premises or utilizing the leased equipment.
Although the obligations may be secured by the leased equipment or facilities,
the disposition of the property in the event of non-appropriation or foreclosure
might prove difficult, time consuming and costly, and result in a delay in
recovering or the failure to fully recover a Fund's 

                                      B-29
<PAGE>
 
original investment. To the extent that a Fund invests in unrated municipal
leases or participates in such leases, the credit quality rating and risk of
cancellation of such unrated leases will be monitored on an ongoing basis.

     Certificates of participation represent undivided interests in municipal
leases, installment purchase agreements or other instruments.  The certificates
are typically issued by a trust or other entity which has received an assignment
of the payments to be made by the state or political subdivision under such
leases or installment purchase agreements.

     Certain municipal lease obligations and certificates of participation may
be deemed to be illiquid for the purpose of the Funds' limitation on investments
in illiquid  securities.  Other municipal lease obligations and certificates of
participation acquired by a Fund may be determined by the Investment Adviser,
pursuant to guidelines adopted by the Trustees of the Trust, to be liquid
securities for the purpose of such limitation. In determining the liquidity of
municipal lease obligations and certificates of participation, the Investment
Adviser will consider a variety of factors, including: (1) the willingness of
dealers to bid for the security; (2) the number of dealers willing to purchase
or sell the obligation and the number of other potential buyers; (3) the
frequency of trades or quotes for the obligation; and (4) the nature of the
marketplace trades. In addition, the Investment Adviser will consider factors
unique to particular lease obligations and certificates of participation
affecting the marketability thereof. These include the general creditworthiness
of the issuer, the importance to the issuer of the property covered by the lease
and the likelihood that the marketability of the obligation will be maintained
throughout the time the obligation is held by a Fund.

     Short Duration Tax-Free, Municipal Income, Core Fixed Income and High Yield
Funds may purchase participations in Municipal Securities held by a commercial
bank or other financial institution.  Such participations provide a Fund with
the right to a pro rata undivided interest in the underlying Municipal
Securities.  In addition, such participations generally provide a Fund with the
right to demand payment, on not more than seven days' notice, of all or any part
of such Fund's participation interest in the underlying Municipal Security, plus
accrued interest.  A Fund will only invest in such participations if, in the
opinion of bond counsel, counsel for the issuers of such participations or
counsel selected by the Investment Adviser, the interest from such
participations is exempt from regular federal income tax.

     Municipal Notes.  Municipal Securities in the form of notes generally are
     ---------------                                                          
used to provide for short-term capital needs, in anticipation of an issuer's
receipt of other revenues or financing, and typically have maturities of up to
three years. Such instruments may include tax anticipation notes, revenue
anticipation notes, bond anticipation notes, tax and revenue anticipation notes
and construction loan notes.  Tax anticipation notes are issued to finance the
working capital needs of governments.  Generally, they are issued in
anticipation of various tax revenues, such as income, sales, property, use and
business taxes, and are payable from these specific future taxes. Revenue
anticipation notes are issued in expectation of receipt of other kinds of
revenue, such as federal revenues available under federal revenue sharing
programs.  Bond anticipation notes are issued to provide interim financing until
long-term bond financing can be arranged.  In most cases, the long-term bonds
then provide the funds needed for repayment of the notes.  Tax and revenue
anticipation 

                                      B-30
<PAGE>
 
notes combine the funding sources of both tax anticipation notes and revenue
anticipation notes. Construction Loan Notes are sold to provide construction
financing. These notes are secured by mortgage notes insured by the FHA;
however, the proceeds from the insurance may be less than the economic
equivalent of the payment of principal and interest on the mortgage note if
there has been a default. The obligations of an issuer of municipal notes are
generally secured by the anticipated revenues from taxes, grants or bond
financing. An investment in such instruments, however, presents a risk that the
anticipated revenues will not be received or that such revenues will be
insufficient to satisfy the issuer's payment obligations under the notes or that
refinancing will be otherwise unavailable.

     Tax-Exempt Commercial Paper.  Issues of commercial paper typically
     ---------------------------                                       
represent short-term, unsecured, negotiable promissory notes.  These obligations
are issued by state and local governments and their agencies to finance working
capital needs of municipalities or to provide interim construction financing and
are paid from general revenues of municipalities or are refinanced with long-
term debt.  In most cases, tax-exempt commercial paper is backed by letters of
credit, lending  agreements, note repurchase agreements or other credit facility
agreements offered by banks or other institutions.

     Pre-Refunded Municipal Securities.  The principal of and interest on pre-
     ---------------------------------                                       
refunded Municipal Securities are no longer paid from the original revenue
source for the securities.  Instead, the source of such payments is typically an
escrow fund consisting of U.S. Government Securities.  The assets in the escrow
fund are derived from the proceeds of refunding bonds issued by the same issuer
as the pre-refunded Municipal Securities.  Issuers of Municipal Securities use
this advance refunding technique to obtain more favorable terms with respect to
securities that are not yet subject to call or redemption by the issuer.  For
example, advance refunding enables an issuer to refinance debt at lower market
interest rates, restructure debt to improve cash flow or eliminate restrictive
covenants in the indenture or other governing instrument for the pre-refunded
Municipal Securities. However, except for a change in the revenue source from
which principal and interest payments are made, the pre-refunded Municipal
Securities remain outstanding on their original terms until they mature or are
redeemed by the issuer.  Pre-refunded Municipal Securities are usually purchased
at a price which represents a premium over their face value.

     Private Activity Bonds.   Municipal Income, Core Fixed Income, High Yield
     ----------------------                                                   
and Short Duration Tax-Free Funds may each invest in certain types of Municipal
Securities, generally referred to as industrial development bonds (and referred
to under current tax law as private activity bonds), which are issued by or on
behalf of public authorities to obtain funds to provide privately operated
housing facilities, airport, mass transit or port facilities, sewage disposal,
solid waste disposal or hazardous waste treatment or disposal facilities and
certain local facilities for water supply, gas or electricity.  Other types of
industrial development bonds, the proceeds of which are used for the
construction, equipment, repair or improvement of privately operated industrial
or commercial facilities,  may constitute Municipal Securities, although the
current federal tax laws place substantial limitations on the size of such
issues.  A Tax Exempt Fund's distributions of its interest income from private
activity bonds may subject certain investors to the federal alternative minimum
tax whereas Core Fixed Income Fund's distributions of any tax-exempt interest it
receives from any source will be taxable for regular federal income tax
purposes.

                                      B-31

     Tender Option Bonds.  A tender option bond is a Municipal Security
     -------------------                                               
(generally held pursuant to a custodial arrangement) having a relatively long
maturity and bearing interest at a fixed rate substantially higher than
prevailing short-term, tax-exempt rates.  The bond is typically issued with the
agreement of a third party, such as a bank, broker-dealer or other financial
institution, which grants the security holders the option, at periodic
intervals, to tender their securities to the institution and receive the face
value thereof. As consideration for providing the option, the financial
institution receives periodic fees equal to the difference between the bond's
fixed coupon rate and the rate, as determined by a remarketing or similar agent
at or near the commencement of such period, that would cause the securities,
coupled with the tender option, to trade at par on the date of such
determination.  Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term, tax-
exempt rate. However, an institution will not be obligated to accept tendered
bonds in the event of certain defaults or a significant downgrade in the credit
rating assigned to the issuer of the bond. The liquidity of a tender option bond
is a function of the credit quality of both the bond issuer and the financial
institution  providing liquidity. Tender option bonds are deemed to be liquid
unless, in the opinion of the Investment Adviser, the credit quality of the bond
issuer and the financial institution is deemed, in light of the Fund's credit
quality requirements, to be inadequate and the bond would not otherwise be
readily marketable. The Tax Exempt Funds intend to invest in tender option bonds
the interest on which will, in the opinion of bond counsel, counsel for the
issuer of interests therein or counsel selected by the Investment Adviser, be
exempt from regular federal income tax.  However, because there can be no
assurance that the Internal Revenue Service (the "IRS") will agree with such
counsel's opinion in any particular case, there is a risk that a Tax Exempt Fund
will not be considered the owner of  such tender option bonds and thus will not
be entitled to treat such interest as exempt from such tax. Additionally, the
federal income tax treatment of certain other aspects of these investments,
including the proper tax treatment of tender option bonds and the associated
fees in  relation to various regulated investment company tax provisions is
unclear. The Tax Exempt Funds intend to manage their portfolio in a manner
designed to eliminate or minimize any adverse impact from the tax rules
applicable to these investments.

     Auction Rate Securities.  Short Duration Tax-Free, Municipal Income, Core
     -----------------------                                                  
Fixed Income and High Yield Funds may invest in auction rate securities.
Auction rate securities consist of auction rate Municipal Securities and auction
rate preferred securities issued by closed-end investment companies that invest
primarily in Municipal Securities (collectively, "auction rate securities").
Provided that the auction mechanism is successful, auction rate securities
usually permit the holder to sell the securities in an auction at par value at
specified intervals.  The dividend is reset by "Dutch" auction in which bids are
made by broker-dealers and other institutions for a certain amount of securities
at a specified minimum yield.  The dividend rate set by the auction is the
lowest interest or dividend rate that covers all securities offered for sale.
While this process is designed to permit auction rate securities to be traded at
par value, there is some risk that an auction will fail due to insufficient
demand for the securities.  A Fund will take the time remaining until the next
scheduled auction date into account for purpose of determining the securities'
duration.

     Dividends on auction rate preferred securities issued by a closed-end fund
may be designated as exempt from federal income tax to the extent they are
attributable to exempt income earned by the fund on the securities in its
portfolio and distributed to holders of the preferred securities, provided that
the preferred securities are treated as equity securities for federal income 

                                      B-32
<PAGE>
 
tax purposes and the closed-end fund complies with certain tests under the
Internal Revenue Code of 1986, as amended (the "Code").

     A Fund's investments in auction rate securities of closed-end funds are
subject to the limitations prescribed by the Act and certain state securities
regulations.  The Funds will indirectly bear their proportionate share of any
management and other fees paid by such closed-end funds in addition to the
advisory fees payable directly by the Funds.

     Insurance.  Short Duration Tax-Free, Municipal Income, Core Fixed Income
     ---------                                                               
and High Yield Funds may invest in "insured" tax-exempt Municipal Securities.
Insured Municipal Securities are securities for which scheduled payments of
interest and principal are guaranteed by a private (non-governmental) insurance
company.  The insurance only entitles a Fund to receive the face or par value of
the securities held by the Fund.  The insurance does not guarantee the market
value of the Municipal Securities or the value of the shares of a Fund.

     Short Duration Tax-Free, Municipal Income, Core Fixed Income and High Yield
Funds may utilize new issue or secondary market insurance.  A new issue
insurance policy is purchased by a bond issuer who wishes to increase the credit
rating of a security. By paying a premium and meeting the insurer's underwriting
standards, the bond issuer is able to obtain a high credit rating (usually, Aaa
from Moody's or AAA from Standard & Poor's) for the issued security.  Such
insurance is likely to increase the purchase price and resale value of the
security.  New issue insurance policies are non-cancelable and continue in force
as long as the bonds are outstanding.

     A secondary market insurance policy is purchased by an investor (such as a
Fund) subsequent to a bond's original issuance and generally insures a
particular bond for the remainder of its term.  The Funds may purchase bonds
which have already been insured under a secondary market insurance policy by a
prior investor, or the Funds may directly purchase such a policy from insurers
for bonds which are currently uninsured.

     An insured Municipal Security acquired by a Fund will typically be covered
by only one of the above types of policies. All of the insurance policies used
by a Fund will be obtained only from insurance companies rated, at the time of
purchase, Aaa by Moody's or AAA by Standard & Poor's.  The Municipal Securities
invested in by High Yield Fund will not be subject to this requirement.

     Standby Commitments.  In order to enhance the liquidity of Municipal
     -------------------                                                 
Securities, the Tax Exempt Funds may acquire the right to sell a security to
another party at a guaranteed price and date. Such a right to resell may be
referred to as a "standby commitment" or liquidity put, depending on its
characteristics. The aggregate price which a Fund pays for securities with
standby commitments may be higher than the price which otherwise would be paid
for the securities.  Standby commitments may not be available or may not be
available on satisfactory terms.

     Standby commitments may involve letters of credit issued by domestic or
foreign banks supporting the other party's ability to purchase the security from
a Tax Exempt Fund.  The right to sell may be exercisable on demand or at
specified intervals, and may form part of a security or be acquired separately
by a Tax Exempt Fund.  In considering whether a security meets a Tax Exempt

                                      B-33
<PAGE>
 
Fund's quality standards, the particular Tax Exempt Fund will look to the
creditworthiness of the party providing the Fund with the right to sell as well
as the quality of the security itself.

     The Tax Exempt Funds value Municipal Securities which are subject to
standby commitments at amortized cost.  The exercise price of the standby
commitments is expected to approximate such amortized cost.  No value is
assigned to the standby commitments for purposes of determining a Tax Exempt
Fund's net asset value. The cost of a standby commitment is carried as
unrealized depreciation from the time of purchase until it is exercised or
expires.  Since the value of a standby commitment is dependent on the ability of
the standby commitment writer to meet its obligation to repurchase, a Tax Exempt
Fund's policy is to enter into standby commitment transactions only with banks,
brokers or dealers which present a minimal risk of default.

     The Investment Adviser understands that the IRS has issued a favorable
revenue ruling to the effect that, under specified circumstances, a registered
investment company will be the owner of tax-exempt municipal obligations
acquired subject to a put option. The IRS has subsequently announced that it
will not ordinarily issue advance ruling letters as to the identity of the true
owner of property in cases involving the sale of securities or participation
interests therein if the purchaser has the right to cause the security, or the
participation interest therein, to be purchased by either the seller or a third
party.  The Tax Exempt Funds intend to take the position that they are the owner
of any Municipal Securities acquired subject to a standby commitment or acquired
or held with certain other types of put rights and that tax-exempt interest
earned with respect to such Municipal Securities will be tax-exempt in their
hands.  There is no assurance that standby commitments will be available to the
Tax Exempt Funds nor have the Tax Exempt Funds assumed that such commitments
would continue to be available under all market conditions.

     Call Risk and Reinvestment Risk.  Municipal Securities may include "call"
     -------------------------------                                          
provisions which permit the issuers of such securities, at any time or after a
specified period, to redeem the securities prior to their stated maturity.  In
the event that Municipal Securities held in a Fund's portfolio are called prior
to the maturity, the Fund will be required to reinvest the proceeds on such
securities at an earlier date and may be able to do so only at lower yields,
thereby reducing the Fund's return on its portfolio securities.

Foreign Investments

     Core Fixed Income, Global Income and High Yield Funds may invest in
securities of foreign issuers and in fixed-income securities quoted or
denominated in a currency other than U.S. dollars.  Investment in foreign
securities may offer potential benefits that are not available from investing
exclusively in U.S. dollar-denominated domestic issues.  Foreign countries may
have economic policies or business cycles different from those of the U.S. and
markets for foreign fixed-income securities do not necessarily move in a manner
parallel to U.S. markets.  Investing in the securities of foreign issuers also
involves, however, certain special considerations, including those set forth
below, which are not typically associated with investing in U.S. issuers.
Investments in the securities of foreign issuers usually involve currencies of
foreign countries and Core Fixed Income, Global Income and High Yield Funds may
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.  To the extent that a Fund is fully invested in
foreign securities while also maintaining currency positions, it may be exposed
to greater combined risk.  A Fund also may be subject to currency exposure
independent of its securities positions.  While the Global Income Fund will have
both long and short currency positions, its net long and short foreign currency
exposure will not exceed the value of the Fund's total assets.

     Currency exchange rates may fluctuate significantly over short periods of
time.  They generally are determined by the forces of supply and demand in the
foreign exchange markets and the relative merits of investments in different
countries, actual or anticipated changes in interest rates and other complex
factors, as seen from an international perspective.  Currency exchange rates
also can be affected unpredictably by intervention by U.S. or foreign
governments or central banks or the failure to intervene or by currency controls
or political developments in the United States or abroad.  To the extent that a
substantial portion of a Fund's total assets, adjusted to reflect the Fund's net
position after giving effect to currency transactions, is denominated or quoted
in the currencies of foreign countries, the Fund will be more susceptible to the
risk of adverse economic and political developments within those countries.  A
Fund's net currency positions may expose it to risks independent of its
securities positions.  In addition, if the payment declines in value against the
U.S. dollar before such income is distributed as dividends to shareholders or
converted to U.S. dollars, the Fund may have to sell portfolio securities to
obtain sufficient cash to pay such dividends.

     Since foreign issuers generally are not subject to uniform accounting,
auditing and financial reporting standards, practices and requirements
comparable to those applicable to U.S. companies, there may be less publicly
available information about a foreign company than about a comparable U.S.
company.  Volume and liquidity in most foreign bond markets are less than in the
United States markets and securities of many foreign companies are less liquid
and more volatile than securities of comparable U.S. companies. Fixed
commissions on foreign securities exchanges are generally higher than negotiated
commissions on U.S. exchanges, although each Fund endeavors to achieve the most
favorable net results on its portfolio transactions.  There is generally less
government supervision and regulation of securities markets and exchanges,
brokers, dealers and listed and unlisted companies than in the United States.
For example, there may be no comparable provisions under certain foreign laws to
insider trading and similar investor protection securities 

                                      B-35
<PAGE>
 
laws that apply with respect to securities transactions consummated in the
United States. Mail service between the United States and foreign countries may
be slower or less reliable than within the United States, thus increasing the
risk of delayed settlement of portfolio transactions or loss of certificates for
portfolio securities.

     Foreign markets also have different clearance and settlement procedures,
and in certain markets there have been times when settlements have been unable
to keep pace with the volume of securities transactions, making it difficult to
conduct such transactions.  Such delays in settlement could result in temporary
periods when a portion of the assets of Core Fixed Income, Global Income or High
Yield Fund is uninvested and no return is earned on such assets.  The inability
of Core Fixed Income, Global Income or High Yield Fund to make intended security
purchases due to settlement problems could cause the Fund to miss attractive
investment opportunities.  Inability to dispose of portfolio securities due to
settlement problems could result either in losses to Core Fixed Income, Global
Income or High Yield Income Fund due to subsequent declines in value of the
portfolio securities, or, if Core Fixed Income, Global Income or High Yield Fund
has entered into a contract to sell the securities, could result in possible
liability to the purchaser. In addition, with respect to certain foreign
countries, there is the possibility of expropriation or confiscatory taxation,
political or social instability, or diplomatic developments which could
adversely affect Core Fixed Income, High Yield or Global Income Funds'
investments in those countries.  Moreover, individual foreign economies may
differ favorably or unfavorably from the U.S. economy in such respects as growth
of gross national product, rate of inflation, capital reinvestment, resources
self-sufficiency and balance of payments position.

Investing in Emerging Countries

     Market Characteristics.  Investment in debt securities of emerging market
     ----------------------                                                   
issuers involve special risks.  The development of a market for such securities
is a relatively recent phenomenon and debt securities of most emerging markets
issuers are less liquid and are generally subject to greater price volatility
than securities of issuers in the United States and other developed countries.
In certain countries, there may be few publicly traded securities, and the
market may be dominated by a few issuers or sectors.  The markets for securities
of emerging markets may have substantially less volume than the market for
similar securities in the United States and may not be able to absorb, without
price disruptions, a significant increase in trading volume or trade size.
Additionally, market making and arbitrage activities are generally less
extensive in such markets, which may contribute to increased volatility and
reduced liquidity of such markets.  The less liquid the market, the more
difficult it may be for a Fund to price accurately its portfolio securities or
to dispose of such securities at the times determined to be appropriate.  The
risks associated with reduced liquidity may be particularly acute to the extent
that a Fund needs cash to meet redemption requests, to pay dividends and other
distributions or to pay its expenses.

     A Fund's purchase and sale of portfolio securities in certain emerging
countries may be constrained by limitations as to daily changes in the prices of
listed securities, periodic trading or settlement volume and/or limitations on
aggregate holdings of foreign investors.  Such limitations may be computed based
on the aggregate trading volume by or holdings of a Fund, the Investment
Adviser, its affiliates and their respective clients and other service
providers.  A Fund may not be 

                                      B-36
<PAGE>
 
able to sell securities in circumstances where price, trading or settlement
volume limitations have been reached.

     Securities markets of emerging markets may also have less efficient
clearance and settlement procedures than U.S. markets, making it difficult to
conduct and complete transactions.  Delays in the settlement could result in
temporary periods when a portion of a Fund's assets is uninvested and no return
is earned thereon.  Inability to make intended security purchases could cause
the Fund to miss attractive investment opportunities.  Inability to dispose of
portfolio securities could result either in losses to a Fund due to subsequent
declines in value of the portfolio security or, if a Fund has entered into a
contract to sell the security, could result in possible liability of a Fund to
the purchaser.

     Transaction costs, including brokerage commissions and dealer mark-ups, in
emerging markets may be higher than in the U.S. and other developed securities
markets.  As legal systems in emerging markets develop, foreign investors may be
adversely affected by new or amended laws and regulations.  In circumstances
where adequate laws exist, it may not be possible to obtain swift and equitable
enforcement of the law.

     With respect to investments in certain emerging market countries, archaic
legal systems may have an adverse impact on a Fund.  For example, while the
potential liability of a shareholder in a U.S. corporation with respect to acts
of the corporation is generally limited to the amount of the shareholder's
investment, the notion of limited liability is less clear in certain emerging
market countries.  Similarly, the rights of investors in emerging market
companies may be more limited than those of shareholders of U.S. corporation.

     Economic, Political and Social Factors.  Emerging markets may be subject to
     --------------------------------------                                     
a greater degree of economic, political and social instability than the United
States, Japan and most Western European countries, and unanticipated political
and social developments may affect the value of a Fund's investments in emerging
markets and the availability to the Fund of additional investments in such
countries.  Moreover, political and economic structures in many emerging markets
may be undergoing significant evolution and rapid development.  Instability may
result from, among other things: (i) authoritarian governments or military
involvement in political and economic decision-making, including changes or
attempted changes in government through extra-constitutional means; (ii) popular
unrest associated with demands for improved economic, political and social
conditions; (iii) internal insurgencies; (iv) hostile relations with neighboring
countries; and (v) ethnic, religious and racial disaffection and conflict.  Many
emerging markets have experienced in the past, and continue to experience, high
rates of inflation.  In certain countries, inflation has at times accelerated
rapidly to hyperinflationary levels, creating a negative interest rate
environment and sharply eroding the value of outstanding financial assets in
those countries.  The economies of many emerging markets are heavily dependent
upon international trade and are accordingly affected by protective trade
barriers and the economic conditions of their trading partners.  In addition,
the economies of some emerging markets may differ unfavorably from the U.S.
economy in such respects as growth of gross domestic product, rate of inflation,
capital reinvestment, resources, self-sufficiency and balance of payments
position.

     Restrictions on Investment and Repatriation.  Certain emerging markets
     -------------------------------------------                           
require governmental approval prior to investments by foreign persons or limit
investments by foreign persons to only a specified percentage of an issuer's
outstanding securities or a specific class of securities which may have less
advantageous terms (including price) than securities of the issuer available for
purchase by nationals.  Repatriation of investment income and capital from
certain emerging markets is subject to certain governmental consents.  Even
where there is no outright restriction on repatriation of capital, the mechanics
of repatriation may affect the operation of a Fund.

     Sovereign Debt Obligations.  Investments in sovereign debt obligations
     --------------------------                                            
involve special risks not present in corporate debt obligations.  The issuer of
the sovereign debt or the governmental authorities that control the repayment of
the debt may be unable or unwilling to repay principal or interest when due, and
a Fund may have limited recourse in the event of a default.  During periods of
economic uncertainty, the market prices of sovereign debt, and a Fund's net
asset value, may be more volatile than prices of debt obligations of U.S.
issuers.  In the past, the governments of certain emerging markets have
encountered difficulties in servicing their debt obligations, withheld payments
of principal and interest and declared moratoria on the payment of principal and
interest on their sovereign debts.

     A sovereign debtor's willingness or ability to repay principal and pay
interest in a timely manner may be affected by, among other factors, its cash
flow situation, the extent of its foreign currency reserves, the availability of
sufficient foreign exchange, the relative size of the debt service burden, the
sovereign debtor's policy toward principal international lenders and local
political constraints.  Sovereign debtors may also be dependent on expected
disbursements from foreign governments, multinational agencies and other
entities to reduce principal and interest arrearages on their debt.  The failure
of a sovereign debtor to implement economic reforms, achieve specified levels of
economic performance or repay principal or interest when due may result in the
cancellation of the third parties' commitments to lend funds to the sovereign
debtor, which may further impair such debtor's ability or willingness to timely
service its debts.

     Brady Bonds.  Certain foreign debt obligations, customarily referred to as
     -----------                                                               
"Brady Bonds," are created through the exchange of existing commercial bank
loans to foreign entities for new obligations in connection with debt
restructuring under a plan introduced by former U.S. Secretary of the Treasury,
Nicholas F. Brady (the "Brady Plan").  Brady Bonds may be fully or partially
collateralized or uncollateralized and issued in various currencies (although
most are U.S. dollar denominated).  In the event of a default on collateralized
Brady Bonds for which obligations are accelerated, the collateral for the
payment of principal will not be distributed to investors, nor will such
obligations be sold and the proceeds distributed.  The collateral will be held
by the collateral agent to the scheduled maturity of the defaulted Brady Bonds,
which will continue to be outstanding, at which time the face amount of the
collateral will equal the principal payments which would have then been due on
the Brady Bonds in the normal course.  In light of the residual risk of the
Brady Bonds, and among other factors, the history of default with respect to
commercial bank loans by public and private entities of countries issuing Brady
Bonds, investments in Brady Bonds may be speculative.

     Forward Foreign Currency Exchange Contracts.  Core Fixed Income, Global
     -------------------------------------------                            
Income and High Yield Funds may enter into forward foreign currency exchange
contracts for hedging purposes and to seek to increase total return.  A forward
foreign currency exchange contract involves an obligation to purchase or sell a
specific currency at a future date, which may be any fixed number of days from
the date of the contract agreed upon by the parties, at a price set at the time
of the contract.  These contracts are traded in the interbank 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 generally charged at any stage for trades.

     At the maturity of a forward contract, Core Fixed Income, Global Income
Fund or High Yield Fund may either accept or make delivery of the currency
specified in the contract or, at or prior to maturity, enter into a closing
purchase transaction involving the purchase or sale of an offsetting contract.
Closing purchase transactions with respect to forward contracts are usually
effected with the currency trader who is a party to the original forward
contract.

     Core Fixed Income, Global Income or High Yield Fund may enter into forward
foreign currency exchange contracts in several circumstances.  First, when a
Fund enters into a contract for the purchase or sale of a security quoted or
denominated in a foreign currency, or when a Fund anticipates the receipt in a
foreign currency of a dividend or interest payment on such a security which it
holds, a Fund may desire to "lock in" the U.S. dollar price of the security or
the U.S. dollar equivalent of such dividend or interest payment, as the case may
be.  By entering into a forward contract for the purchase or sale, for a fixed
amount of U.S. dollars, of the amount of foreign currency involved in the
underlying transactions, a Fund may attempt to protect itself against an adverse
change in the relationship between the U.S. dollar and the subject foreign
currency during the period between the date on which the security is purchased
or sold, or on which the dividend or interest payment is declared, and the date
on which such payments are made or received.

     Additionally, when the Investment Adviser believes that the currency of a
particular foreign country may suffer a substantial decline against the U.S.
dollar, it may enter into a forward contract to sell, for a fixed amount of U.S.
dollars, the amount of foreign currency approximating the value of some or all
of a Fund's portfolio securities quoted or denominated in such foreign currency.
The precise matching of the forward contract amounts and the value of the
securities involved will not generally be possible because the future value of
such securities in foreign currencies will change as a consequence of market
movements in the value of those securities between the date on which the
contract is entered into and the date it matures.  Using forward contracts to
protect the value of a Fund's portfolio securities against a decline in the
value of a currency does not eliminate fluctuations in the underlying prices of
the securities.  It simply establishes a rate of exchange which a Fund can
achieve at some future point in time. The precise projection of short-term
currency market movements is not possible, and short-term hedging provides a
means of fixing the U.S. dollar value of only a portion of a Fund's foreign
assets.

     Core Fixed Income, Global Income and High Yield Funds may engage in cross-
hedging by using forward contracts in one currency to hedge against fluctuations
in the value of securities denominated or quoted in a different currency if the
Investment Adviser determines that there is a pattern of correlation between the
two currencies.

                                      B-39
<PAGE>
 
     Unless otherwise covered, cash or liquid assets will be segregated in an
amount equal to the value of the fund's total assets committed to the
consummation of forward foreign currency exchange contracts requiring the fund
to purchase foreign currencies and forward contracts entered into to seek to
increase total return.  The segregated assets will be marked-to-market.  If the
value of the segregated assets declines, additional liquid assets will be
segregated so that the value will equal the amount of the fund's commitments
with respect to such contracts.  Although the contracts are not presently
regulated by the Commodity Futures Trading Commission ("CFTC"), the CFTC may in
the future assert authority to regulate these contracts. In such event, a fund's
ability to utilize forward foreign currency exchange contracts may be
restricted.  Gincome, core fixed income and high yield funds will not
enter into a forward contract with a term of greater than one year.

     While Core Fixed Income, Global Income, and High Yield Funds may enter into
forward contracts to seek to reduce currency exchange rate risks, transactions
in such contracts involve certain other risks.  Thus, while the Funds may
benefit from such transactions, unanticipated changes in currency prices may
result in a poorer overall performance for a Fund than if it had not engaged in
any such transactions.  Moreover, there may be imperfect correlation between a
Fund's portfolio holdings of securities quoted or denominated in a particular
currency and forward contracts entered into by a Fund.  Such imperfect
correlation may cause the Fund to sustain losses which will prevent the Fund
from achieving a complete hedge or expose the Fund to risk of foreign exchange
loss.

     Markets for trading forward foreign currency contracts offer less
protection against defaults than is available when trading in currency
instruments on an exchange. Forward contracts are subject to the risk that the
counterparty to such contract will default on its obligations. Since a forward
foreign currency exchange contract is not guaranteed by an exchange or
clearinghouse, a default on the contract would deprive a fund of unrealized
profits, transaction costs or the benefits of a currency hedge or force the fund
to cover its purchase or sale commitments, if any, at the current market price.
A Fund will not enter into forward foreign currency exchange contracts, unless
the credit quality of the unsecured senior debt or the claims-paying ability of
the counterparty is considered to be investment grade by the investment adviser.
To the extent that a substantial portion of a fund's total assets, adjusted to
reflect the fund's net position after giving effect to currency transactions, is
denominated or quoted in the currencies of foreign countries, the fund will be
more susceptible to the risk of adverse economic and political developments
within those countries.

Interest Rate Swaps, Mortgage Swaps, Credit Swaps, Currency Swaps and Interest
Rate Caps, Floors and Collars

     Each Fund may enter into interest rate swaps, credit swaps, caps, floors
and collars.  In addition, Adjustable Rate Government, Short Duration
Government, Government Income, Core Fixed INcome, Global Income and High Yield
Funds may enter into mortgage swaps; and core fixed income, high yield and
global income funds may enter into currency swaps.  Each fund may enter into
swap transactions for hedging purposes or to seek to increase total return.
Interest rate swaps involve the exchange by a fund with another party of their
respective commitments to 

                                      B-40
<PAGE>
 
pay or receive interest, such as an exchange of fixed-rate payments for floating
rate payments. Mortgage swaps are similar to interest rate swaps in that they
represent commitments to pay and receive interest. The notional principal
amount, however, is tied to a reference pool or pools of mortgages. Credit swaps
involve the receipt of floating or fixed rate payments in exchange for assuming
potential credit losses of an underlying security. Credit swaps give one party
to a transaction the right to dispose of or acquire an asset (or group of
assets), or the right to receive or make a payment from the other party, upon
the occurrence of specified credit events. Currency swaps involve the exchange
of the parties' respective rights to make or receive payments in specified
currencies. The purchase of an interest rate cap entitles the purchaser, to the
extent that a specified index exceeds a predetermined interest rate, to receive
payment of interest on a notional principal amount from the party selling such
interest rate cap. The purchase of an interest rate floor entitles the
purchaser, to the extent that a specified index falls below a predetermined
interest rate, to receive payments of interest on a notional principal amount
from the party selling the interest rate floor. An interest rate collar is the
combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates. Since interest rate, mortgage, credit and
currency swaps and interest rate caps, floors and collars are individually
negotiated, each Fund expects to achieve an acceptable degree of correlation
between its portfolio investments and its swap, cap, floor and collar positions.

     A Fund will enter into interest rate and mortgage swaps only on a net
basis, which means that the two payment streams are netted out, with the Fund
receiving or paying, as the case may be, only the net amount of the two
payments.  Interest rate and mortgage swaps do not involve the delivery of
securities, other underlying assets or principal.  Accordingly, the risk of loss
with respect to interest rate and mortgage swaps is limited to the net amount of
payments that a Fund is contractually obligated to make.  If the other party to
an interest rate swap defaults, a Fund's risk of loss consists of the net amount
of payments that such Fund is contractually entitled to receive, if any.  In
contrast, currency swaps usually involve the delivery of the entire principal
amount of one designated currency in exchange for the other designated currency.
Therefore, the entire principal value of a currency swap is subject to the risk
that the other party to the swap will default on its contractual delivery
obligations.  To the extent that the net amount payable under an interest rate,
index or mortgage swap and the entire amount of the payment stream payable by a
Fund under a currency swap or an interest rate floor, cap or collar are covered
by segregated cash or liquid assets, the Funds and its Investment Adviser
believes that transactions do not constitute senior securities under the Act
and, accordingly, will not treat them as being subject to a fund's borrowing
restrictions.

     The Funds will not enter into any interest rate, mortgage or credit swap
transactions unless the unsecured commercial paper, senior debt or claims-paying
ability of the other party is rated either A or A-1 or better by Standard &
Poor's or A or P-1 or better by Moody's or their equivalent ratings.  Core
Fixed Income, Global Income and High Yield Funds will not enter into any
currency swap transactions unless the unsecured commercial paper, senior debt or
claimspaying ability of the other party thereto is rated investment grade by
Standard & Poor's or Moody's, or, if unrated by such rating organization,
determined to be of comparable quality by the Investment Adviser.  If there is a
default by the other party to such a transaction, a Fund will have contractual
remedies pursuant to  the agreements related to the transaction.  The swap
market has grown 

                                      B-41
<PAGE>
 
substantially in recent years with a large number of banks and investment
banking firms acting both as principals and as agents utilizing standardized
swap documentation. As a result, the swap market has become relatively liquid in
comparison with the markets for other similar instruments which are traded in
the interbank market. The Investment Adviser, under the supervision of the Board
of Trustees, is responsible for determining and monitoring the liquidity of the
Funds' transactions in swaps, caps, floors and collars.

     The use of interest rate, mortgage, credit and currency swaps, as well as
interest rate caps, floors and collars, is a highly specialized activity which
involves investment techniques and risks different from those associated with
ordinary portfolio securities transactions.  If the Investment Adviser is
incorrect in its forecasts of market values, interest rates and currency
exchange rates, the investment performance of a Fund would be less favorable
than it would have been if this investment technique were not used.

Options on Securities and Securities Indices

     Writing Covered Options. Each Fund may write (sell) covered call and put
     -----------------------                                                 
options on any securities in which it may invest or on any securities index
based on securities in which it may invest.  A Fund may purchase and write such
options on securities that are listed on national domestic securities exchanges
or foreign securities exchanges or traded in the over-the-counter market.  A
call option written by a Fund obligates such Fund to sell specified securities
to the holder of the option at a specified price if the option is exercised at
any time before the expiration date.  All call options written by a Fund are
covered, which means that such Fund will own the securities subject to the
option so long as the option is outstanding or such Fund will use the other
methods described below.  The Fund's purpose in writing covered call options is
to realize greater income than would be realized on portfolio securities
transactions alone. However, a Fund may forego the opportunity to profit from an
increase in the market price of the underlying security.

     A put option written by a Fund obligates the Fund to purchase specified
securities from the option holder at a specified price if the option is
exercised at any time before the expiration date. All put options written by a
Fund would be covered, which means that such Fund would have segregated cash or
liquid assets with a value at least equal to the exercise price of the put
option.  The purpose of writing such options is to generate additional income
for the Fund.  However, in return for the option premium, each Fund accepts the
risk that it may be required to purchase the underlying securities at a price in
excess of the securities' market value at the time of purchase.

     All call and put options written by a Fund are covered.  A written call
option or put option may be covered by (i) segregating cash or liquid assets, as
permitted by applicable law, either of which, in the case of Core Fixed Income,
Global Income Fund or High Yield Fund, may be quoted or denominated in any
currency, with a value at least equal to the Fund's obligation under the option,
(ii) entering into an offsetting forward commitment, and/or (iii) purchasing an
offsetting option or any other option which, by virtue of its exercise price or
otherwise, reduces the Fund's net exposure on its written option position.

                                      B-42
<PAGE>
 
     A Fund may terminate its obligations under an exchange-traded call or put
option by purchasing an option identical to the one it has written.  Obligations
under over-the-counter options may be terminated only by entering into an
offsetting transaction with the counterparty to such option.   Such purchases
are referred to as "closing purchase transactions."

     Each Fund may also write (sell) covered call and put options on any
securities index composed of securities in which it may invest.  Options on
securities indices are similar to options on securities, except that the
exercise of securities index options requires cash settlement payments and does
not involve the actual purchase or sale of securities.  In addition, securities
index options are designed to reflect price fluctuations in a group of
securities or segment of the securities market rather than price fluctuations in
a single security.

     The Funds may cover call options on a securities index by owning securities
whose price changes are expected to be similar to those of the underlying index
or by having an absolute and immediate right to acquire such securities without
additional cash consideration (or for additional cash consideration that is
segregated) upon conversion or exchange of other securities in its portfolio.
The Funds may also cover call and put options on a securities index by
segregating cash or liquid assets, as permitted by applicable law, with a value
equal to the exercise price or by using the other methods described above.

     The writing and purchase of options is a highly specialized activity which
involves investment techniques and risks different from those associated with
ordinary portfolio securities transactions.  The use of options to seek to
increase total return involves the risk of loss if the Investment Adviser is
incorrect in its expectation of fluctuations in securities prices or interest
rates.  The successful use of options for hedging purposes also depends in part
on the ability of the Investment Adviser to predict future price fluctuations
and the degree of correlation between the options and securities markets.  If
the Investment Adviser is incorrect in its expectation of changes in securities
prices or determination of the correlation between the securities indices on
which options are written and purchased and the securities in a Fund's
investment portfolio, the investment performance of the Fund will be less
favorable than it would have been in the absence of such options transactions.
the writing of options could increase a Fund's portfolio turnover rate and,
therefore, associated brokerage commissions or spreads.

     Purchasing Options.  Each Fund may also purchase put and call options on
     ------------------                                                      
any securities in which it may invest or options on any securities index
composed of securities in which it may invest. A Fund would also be able to
enter into closing sale transactions in order to realize gains or minimize
losses on options it had purchased.

     A Fund would normally purchase call options in anticipation of an increase,
or put options in anticipation of a decrease ("protective puts"), in the market
value of securities of the type in which it may invest.  The purchase of a call
option would entitle a Fund, in return for the premium paid, to purchase
specified securities at a specified price during the option period. A Fund would
ordinarily realize a gain on the purchase of a call option if, during the option
period, the value of such securities exceeded the sum of the exercise price, the
premium paid and transaction costs; otherwise the Fund would realize either no
gain or a loss on the purchase of the call option.  The purchase of a put option
would entitle a Fund, in exchange for the premium paid, to sell specified

                                      B-43
<PAGE>
 
securities at a specified price during the option period. The purchase of
protective puts is designed to offset or hedge against a decline in the market
value of a Fund's securities. Put options may also be purchased by a Fund for
the purpose of affirmatively benefiting from a decline in the price of
securities which it does not own. A Fund would ordinarily realize a gain if,
during the option period, the value of the underlying securities decreased below
the exercise price sufficiently to cover the premium and transaction costs;
otherwise the Fund would realize either no gain or a loss on the purchase of the
put option.  Gains and losses on the purchase of put options may be offset by
countervailing changes in the value of the underlying portfolio securities.

     A Fund may purchase put and call options on securities indices for the same
purposes as it may purchase options on securities. Options on securities indices
are similar to options on securities, except that the exercise of securities
index options requires cash payments and does not involve the actual purchase or
sale of securities.  In addition, securities index options are designed to
reflect price fluctuations in a group of securities or segment of the securities
market rather than price fluctuations in a single security.

     Writing and Purchasing Currency Call and Put Options.  Core Fixed Income,
     ----------------------------------------------------                     
Global Income and High Yield Funds may write covered put and call options and
purchase put and call options on foreign currencies in an attempt to protect
against declines in the U.S. dollar value of foreign portfolio securities and
against increases in the U.S. dollar cost of foreign securities to be acquired.
Global Income, Core Fixed Income and High Yield Funds may use options on
currency to cross-hedge, which involves writing or purchasing options on one
currency to seek to hedge against changes in exchange rates for a different
currency with a pattern of correlation.  As with other kinds of option
transactions, however, the writing of an option on foreign currency will
constitute only a partial hedge, up to the amount of the premium received.  If
an option that a Fund has written is exercised, the Fund could be required to
purchase or sell foreign currencies at disadvantageous exchange rates, thereby
incurring losses.  The purchase of an option on foreign currency may constitute
an effective hedge against exchange rate fluctuations; however, in the event of
exchange rate movements adverse to a Fund's position, the Fund may forfeit the
entire amount of the premium plus related transaction costs.  In addition, Core
Fixed Income, Global Income and High Yield Funds may purchase call options on
currency to seek to increase total return.

     A call option written by Core Fixed Income, Global Income or High Yield
Fund obligates the Fund to sell specified currency to the holder of the option
at a specified price if the option is exercised at any time before the
expiration date.  A put option written by a Fund obligates the Fund to purchase
specified currency from the option holder at a specified price if the option is
exercised at any time before the expiration date.  The writing of currency
options involves a risk that a Fund will, upon exercise of the option, be
required to sell currency subject to a call at a price that is less than the
currency's market value or be required to purchase currency subject to a put at
a price that exceeds the currency's market value.

     A Fund may terminate its obligations under a written call or put option by
purchasing an option identical to the one written. Such purchases are referred
to as "closing purchase transactions." A Fund may enter into closing sale
transactions in order to realize gains or minimize losses on purchased options.

                                      B-44
<PAGE>
 
     Core Fixed Income, Global Income and High Yield Funds would normally
purchase call options in anticipation of an increase in the U.S. dollar value of
currency in which securities to be acquired by the Fund are denominated or
quoted. The purchase of a call option would entitle a Fund, in return for the
premium paid, to purchase specified currency at a specified price during the
option period. A Fund would ordinarily realize a gain if, during the option
period, the value of such currency exceeded the sum of the exercise price, the
premium paid and transaction costs; otherwise, the Fund would realize either no
gain or a loss on the purchase of the call option.

     Core Fixed Income, Global Income and High Yield Funds would normally
purchase put options in anticipation of a decline in the U.S. dollar value of
currency in which securities in its portfolio are denominated or quoted
("protective puts"). The purchase of a put option would entitle core fixed
income, global income and High Yield Funds, in exchange for the premium paid, to
sell specified currency at a specified price  during the option period.  The
purchase of protective puts is designed merely to offset or hedge against a
decline in the U.S. dollar value of a Fund's portfolio securities due to
currency exchange rate fluctuations.  A Fund would ordinarily realize a gain if,
during the option period, the value of the underlying currency decreased below
the exercise price sufficiently to more than cover the premium and transaction
costs; otherwise, the Fund would realize either no gain or a loss on the
purchase of the put option.  Gains and losses on the purchase of protective put
options would tend to be offset by countervailing changes in the value of the
underlying currency.

     In addition to using options for the hedging purposes described above, core
Fixed Income, Global Income and High Yield Funds may use options on currency to
seek to increase total return.  Core Fixed Income, Global Income and High Yield
Funds may write (sell) covered put and call options on any currency in an
attempt to realize greater income than would be realized on portfolio securities
transactions alone.  However, in writing covered call options for additional
income, Core Fixed Income, Global Income and High Yield Funds may forego the
opportunity to profit from an increase in the market value of the underlying
currency.  Also, when writing put options, Core Fixed Income, Global Income and
High Yield Funds accept, in return for the option premium, the risk that it may
be required to purchase the underlying currency at a price in excess of the
currency's market value at the time of purchase.

     Core Fixed Income, Global Income and High Yield Funds would normally
purchase call options to seek to increase total return in anticipation of an
increase in the market value of a currency.  Core Fixed Income, Global Income
and High Yield Funds would ordinarily realize a gain if, during the option
period, the value of such currency exceeded the sum of the exercise price, the
premium paid and transaction costs.  Otherwise Core Fixed Income, Global Income
and High Yield Funds would realize either no gain or a loss on the purchase of
the call option.  Put options may be purchased by the Core Fixed Income, GlobalI
income and High Yield Funds for the purpose of benefiting from a decline in the
value of currencies which it does not own. Core Fixed Income, Global Income and 
High Yield Funds would ordinarily realize a gain if, during the option period,
the value of the underlying currency decreased below the exercise price
sufficiently to more than cover the premium and transaction costs.  Otherwise,
core fixed income, global income and High Yield Funds would realize either no
gain or a loss on the purchase of the put option.

                                      B-45

     Yield Curve Options.  Each Fund may enter into options on the yield
     -------------------                                                
"spread" or differential between two securities. Such transactions are referred
to as "yield curve" options.  In contrast to other types of options, a yield
curve option is based on the difference between the yields of designated
securities, rather than the prices of the individual securities, and is settled
through cash payments.  Accordingly, a yield curve option is profitable to the
holder if this differential widens (in the case of a call) or narrows (in the
case of a put), regardless of whether the yields of the underlying securities
increase or decrease.

     A Fund may purchase or write yield curve options for the same purposes as
other options on securities.  For example, a Fund  may purchase a call option on
the yield spread between two securities if the fund owns one of the securities
and anticipates purchasing the other security and wants to hedge against an
adverse change in the yield spread between the two securities.  A Fund may also
purchase or write yield curve options in an effort to increase current income
if, in the judgment of the Investment Adviser, the Fund will be able to profit
from movements in the spread between the yields of the underlying securities.
The trading of yield curve options is subject to all of the risks associated
with the trading of other types of options.  In addition, however, such options
present a risk of loss even if the yield of one of the underlying securities
remains constant, or if the spread moves in a direction or to an extent which
was not anticipated.

     Yield curve options written by a Fund will be "covered."  A call (or put)
option is covered if the Fund holds another call (or put) option on the spread
between the same two securities and segregates cash or liquid assets sufficient
to cover the Fund's net liability under the two options. Therefore, a Fund's
liability for such a covered option is generally limited to the difference
between the amount of the Fund's liability under the option written by the Fund
less the value of the option held by the Fund. Yield curve options may also be
covered in such other manner as may be in accordance with the requirements of
the counterparty with which the option is traded and applicable laws and
regulations. Yield curve options are traded over-the-counter, and the trading
markets for these options may not be as developed as the market for other types
of options.

     Risks Associated with Options Transactions.  There is no assurance that a
     ------------------------------------------                               
liquid secondary market on a domestic or foreign options exchange will exist for
any particular exchange-traded option or at any particular time.  If a Fund is
unable to effect a closing purchase transaction with respect to covered options
it has written, the Fund will not be able to sell the underlying securities or
dispose of assets held in a segregated account until the options expire or are
exercised.  Similarly, if a Fund is unable to effect a closing sale transaction
with respect to options it has purchased, it will have to exercise the options
in order to realize any profit and will incur transaction costs upon the
purchase or sale of underlying securities.

     Reasons for the absence of a liquid secondary market on an exchange
include, but are not limited to, the following:  (i) there may be insufficient
trading interest in certain options; (ii) restrictions may be imposed by an
exchange on opening or closing transactions or both; (iii) trading halts,
suspensions or other restrictions may be imposed with respect to particular
classes or series of options; (iv) unusual or unforeseen circumstances may
interrupt normal operations on an exchange; (v) the facilities of an exchange or
the Options Clearing Corporation may not at all times be adequate to handle
current trading volume; or (vi) one or more exchanges could, for economic or

                                      B-46
<PAGE>
 
other reasons, decide or be compelled at some future date to discontinue the
trading of options (or a particular class or series of options), in which event
the secondary market on that exchange (or in that class or series of options)
would cease to exist although outstanding options on that exchange that had been
issued by the Options Clearing Corporation as a result of trades on that
exchange would continue to be exercisable in accordance with their terms.

     A Fund may purchase and sell both options that are traded on U.S. and
foreign exchanges and options traded over-the-counter with broker-dealers who
make markets in these options.  The ability to terminate over-the-counter
options is more limited than with exchange-traded options and may involve the
risk that broker-dealers participating in such transactions will not fulfill
their obligations.

     Transactions by a Fund in options will be subject to limitations
established by each of the exchanges, boards of trade or other trading
facilities on which such options are traded governing the maximum number of
options in each class which may be written or purchased by a single investor or
group of investors acting in concert regardless of whether the options are
written or purchased on the same or different exchanges, boards of trade or
other trading facilities or are held or written in one or more accounts or
through one of more brokers.  Thus, the number of options which a Fund may write
or purchase may be affected by options written or purchased by other investment
advisory clients or the Funds' Investment Adviser.  An exchange, board of trade
or other trading facility may order the liquidation of positions found to be in
excess of these limits, and it may impose certain other sanctions.

Futures Contracts and Options on Futures Contracts

     Each Fund may purchase and sell various kinds of futures contracts, and
purchase and write call and put options on any of such futures contracts.  Each
Fund may also enter into closing purchase and sale transactions with respect to
any of such contracts and options. The futures contracts may be based on various
securities (such as U.S. Government Securities), securities indices, foreign
currencies in the case of Global Income, Core Fixed Income and High Yield Funds
and any other financial instruments and indices.  Each Fund will engage in
futures and related options transactions, only for bona fide hedging purposes as
defined below or for purposes of seeking to increase total return to the extent
permitted by regulations of the CFTC.  Futures contracts entered into by a Fund
are traded on U.S. exchanges or boards of trade that are licensed and regulated
by the CFTC or on foreign exchanges.  Neither the CFTC, National Futures
Association nor any domestic exchange regulates activities of any foreign
exchange or boards of trade, including the execution, delivery and clearing of
transactions, or has the power to compel enforcement of the rules of a  foreign
exchange or board of trade or any applicable foreign law.  This is true even if
the exchange is formally linked to a domestic market so that a position taken on
the market may be liquidated by a transaction on another market.  Moreover, such
laws or regulations will vary depending on the foreign country in which the
foreign futures or foreign options transaction occurs.  For these reasons,
persons who trade foreign futures or foreign options contracts may not be
afforded certain of the protective measures provided by the Commodity Exchange
Act, the CFTC's regulations and the rules of the National Futures Association
and any domestic exchange, including the right to use reparations proceedings
before the CFTC and arbitration proceedings provided by the National Futures
Association or any domestic futures 

                                      B-47
<PAGE>
 
exchange. In particular, a Fund's investments in foreign futures or foreign
options transactions may not be provided the same protections in respect of
transactions on United States futures exchanges.

     Futures Contracts.  A futures contract may generally be described as an
     -----------------                                                      
agreement between two parties to buy and sell particular financial instruments
or currencies for an agreed price during a designated month (or to deliver the
final cash settlement price, in the case of a contract relating to an index or
otherwise not calling for physical delivery at the end of trading in the
contract).

     When interest rates are rising or securities prices are falling, a Fund can
seek to offset a decline in the value of its current portfolio securities
through the sale of futures contracts. When interest rates are falling or
securities prices are rising, a Fund, through the purchase of futures contracts,
can attempt to secure better rates or prices than might later be available in
the market when it effects anticipated purchases. Core Fixed Income, Global
Income and High Yield Funds may each seek to offset anticipated changes in the
value of a currency in which its portfolio securities, or securities that it
intends to purchase, are quoted or denominated by purchasing and selling futures
contracts on such currencies.

     Positions taken in the futures markets are not normally held to maturity
but are instead liquidated through offsetting transactions which may result in a
profit or a loss.  While futures contracts on securities or currency will
usually be liquidated in this manner, a Fund may instead make, or take, delivery
of the underlying securities or currency whenever it appears economically
advantageous to do so. A clearing corporation associated with the exchange on
which futures on securities or currency are traded guarantees that, if still
open, the sale or purchase will be performed on the settlement date.

     Hedging Strategies.  Hedging, by use of futures contracts, seeks to
     ------------------                                                 
establish with more certainty than would otherwise be possible the effective
price or rate of return on portfolio securities or securities that a Fund
proposes to acquire or the exchange rate of currencies in which portfolio
securities are quoted or denominated.  A Fund may, for example, take a "short"
position in the futures market by selling futures contracts to seek to hedge
against an anticipated rise in interest rates or a decline in market prices or
foreign currency rates that would adversely affect the U.S. dollar value of the
Fund's portfolio securities.  Such futures contracts may include contracts for
the future delivery of securities held by a Fund or securities with
characteristics similar to those of a Fund's portfolio securities. Similarly,
Core Fixed Income, Global Income and High Yield Funds may each sell futures
contracts on any currencies in which its portfolio securities are quoted or
denominated or in one currency to seek to hedge against fluctuations in the
value of securities denominated in a different currency if there is an
established historical pattern of correlation between the two currencies.  If,
in the opinion of the Investment Adviser, there is a sufficient degree of
correlation between price trends for a Fund's portfolio securities and futures
contracts based on other financial instruments, securities indices or other
indices, the Funds may also enter into such futures contracts as part of its
hedging strategy.  Although under some circumstances prices of securities in a
Fund's portfolio may be more or less volatile than prices of such futures
contracts, the Investment Adviser will attempt to estimate the extent of this
volatility difference based on historical patterns and compensate for any such
differential by having a Fund enter into a greater or 

                                      B-48
<PAGE>
 
lesser number of futures contracts or by attempting to achieve only a partial
hedge against price changes affecting a Fund's portfolio securities. When
hedging of this character is successful, any depreciation in the value of
portfolio securities will be substantially offset by appreciation in the value
of the futures position. on the other hand, any unanticipated appreciation in
the value of a Fund's portfolio securities would be substantially offset by a
decline in the value of the futures position.

     On other occasions, a Fund may take a "long" position by purchasing futures
contracts.  This would be done, for example, when a Fund anticipates the
subsequent purchase of particular securities when it has the necessary cash, but
expects the prices or currency exchange rates then available in the applicable
market to be less favorable than prices that are currently available.

     Options on Futures Contracts.  The acquisition of put and call options on
     ----------------------------                                             
futures contracts will give a Fund the right (but not the obligation) for a
specified price to sell or to purchase, respectively, the underlying futures
contract at any time during the option period.  As the purchaser of an option on
a futures contract, a Fund obtains the benefit of the futures position if prices
move in a favorable direction but limits its risk of loss in the event of an
unfavorable price movement to the loss of the premium and transaction costs.

     The writing of a call option on a futures contract generates a premium
which may partially offset a decline in the value of a Fund's assets.  By
writing a call option, a Fund becomes obligated, in exchange for the premium, to
sell a futures contract if the option is exercised, which may have a value
higher than the exercise price. Conversely, the writing of a put option on a
futures contract generates a premium which may partially offset an increase in
the price of securities that a fund intends to purchase.  However, a Fund
becomes obligated (upon exercise of the option) to purchase a futures contract
if the option is exercised, which may have a value lower than the exercise
price. Thus, the loss incurred by a Fund in writing options on futures is
potentially unlimited and may exceed the amount of the premium received.  The
Funds will incur transaction costs in connection with the writing of options on
futures.

     The holder or writer of an option on a futures contract may terminate its
position by selling or purchasing an offsetting option on the same financial
instrument.  There is no guarantee that such closing transactions can be
effected.  A Fund's ability to establish and close out positions on such options
will be subject to the development and maintenance of a liquid market.

     Other Considerations.  Each Fund will engage in futures and related options
     --------------------                                                       
transactions only for bona fide hedging or to seek to increase total return as
permitted by CFTC regulations which permit principals of an investment company
registered under the act to engage in such transactions without registering as
commodity pool operators.

     In addition to bona fide hedging, a CFTC regulation permits a Fund to
engage in other futures transactions if the aggregate initial margin and
premiums required to establish such positions in futures contracts and options
on futures do not exceed 5% of the net asset value of a Fund's portfolio, after
taking into account unrealized profits and losses on any such positions and
excluding the amount by which such options were in-the-money at the time of
purchase.  The Funds will 

                                      B-49
<PAGE>
 
engage in transactions in futures contracts and related options only to the
extent such transactions are consistent with the requirements of the Code for
maintaining their qualifications as regulated investment companies for federal
income tax purposes.

     Transactions in futures contracts and options on futures involve brokerage
costs, require margin deposits and, in the case of contracts and options
obligating a Fund to purchase securities or currencies, require the Fund to
segregate cash or liquid assets, as permitted by applicable law, in an amount
equal to the underlying value of such contracts and options.

     While transactions in futures contracts and options on futures may reduce
certain risks, such transactions themselves entail certain other risks.  Thus,
while a Fund may benefit from the use of futures and options on futures,
unanticipated changes in interest rates or securities prices or currency
exchange rates may result in a poorer overall performance for a Fund than if it
had not entered into any futures contracts or options transactions.  In the
event of an imperfect correlation between a futures position and a portfolio
position which is intended to be protected, the desired protection may not be
obtained and a Fund may be exposed to risk of loss.

     Perfect correlation between a Fund's futures positions and portfolio
positions will be impossible to achieve.  There are no futures contracts based
upon individual securities, except certain U.S. Government Securities.  The only
futures contracts available to hedge a Fund's portfolio are various futures on
U.S. Government Securities, securities indices and foreign currencies. In
addition, it is not possible to hedge fully or protect against currency
fluctuations affecting the value of securities denominated in foreign currencies
because the value of such securities is likely to fluctuate as a result of
independent factors not related to currency fluctuations.

     The profitability of a Fund's trading in futures to seek to increase total
return depends upon the ability of the investment adviser to analyze correctly
the futures markets.

Mortgage Dollar Rolls

     The Taxable Funds (other than High Yield Fund) may enter into mortgage
"dollar rolls" in which a Fund sells securities for delivery in the current
month and simultaneously contracts with the same counterparty to repurchase
similar (same type, coupon and maturity), but not identical securities on a
specified future date.  During the roll period, a Fund loses the right to
receive principal and interest paid on the securities sold.  However, a Fund
would benefit to the extent of any difference between the price received for the
securities sold and the lower forward price for the future purchase (often
referred to as the "drop") or fee income plus the interest earned on the cash
proceeds of the securities sold until the settlement date of the forward
purchase. Unless such benefits exceed the income, capital appreciation and gain
or loss due to mortgage prepayments that would have been realized on the
securities sold as part of the mortgage dollar roll, the use of this technique
will diminish the investment performance of a Fund compared with what such
performance would have been without the use of mortgage dollar rolls.  All cash
proceeds will be invested in instruments that are permissible investments for
the applicable Fund.  Each Fund will hold and maintain in a segregated account
until the settlement date cash or liquid assets, as permitted by applicable law,
in an amount equal to its forward purchase price.

     For financial reporting and tax purposes, the Funds treat mortgage dollar
rolls as two separate transactions; one involving the purchase of a security and
a separate transaction involving a sale.  The Funds do not currently intend to
enter into mortgage dollar rolls that are accounted for as a financing.

     Mortgage dollar rolls involve certain risks including the following:  if
the broker-dealer to whom a Fund sells the security becomes insolvent, a Fund's
right to purchase or repurchase the mortgage-related securities subject to the
mortgage dollar roll may be restricted and the instrument which a Fund is
required to repurchase may be worth less than an instrument which a Fund
originally held.  Successful use of mortgage dollar rolls will depend upon the
Investment Adviser's ability to manage a Fund's interest rate and mortgage
prepayments exposure.  For these reasons, there is no assurance that mortgage
dollar rolls can be successfully employed.

Convertible Securities

     Convertible securities include corporate notes or preferred stock but are
ordinarily long-term debt obligations of the issuer convertible at a stated
exchange rate into common stock of the issuer.  As with all debt securities, the
market value of convertible securities tends to decline as interest rates
increase and, conversely, to increase as interest rates decline. Convertible
securities generally offer lower interest or dividend yields than non-
convertible securities of similar quality. However, when the market price of the
common stock underlying a convertible security exceeds the conversion price, the
price of the convertible security tends to reflect the value of the underlying
common stock.  As the market price of the underlying common stock declines, the
convertible security tends to trade increasingly on a yield basis, and thus may
not depreciate to the same extent as the underlying common stock.  Convertible
securities rank senior to common stocks in an issuer's capital structure and
consequently entail less risk than the issuer's common stock.

                                      B-51
<PAGE>
 
     Unlike debt securities, the obligations of an issuer of preferred stock,
including dividend and other payment obligations, may not typically be
accelerated by the holders of preferred stock on the occurrence of an event of
default (such as a covenant default or filing of a bankruptcy petition) or other
non-compliance by the issuer with the terms of the preferred stock.  Often,
however, on the occurrence of any such event of default or non-compliance by the
issuer, preferred stockholders will be entitled to gain representation on the
issuer's board of directors or increase their existing board representation.  In
addition, preferred stockholders may be granted voting rights with respect to
certain issues on the occurrence of any event of default.

Lending of Portfolio Securities

     Each Fund may lend portfolio securities.  Under present regulatory
policies, such loans may be made to institutions, such as brokers or dealers and
would be required to be secured continuously by collateral in cash, cash
equivalents, letters of credit or U.S. Government Securities maintained on a
current basis at an amount at least equal to the market value of the Securities
loaned. A Fund would be required to have the right to call a loan and obtain the
securities loaned at any time on five days' notice. for the duration of a loan,
a Fund would continue to receive the equivalent of the interest or dividends
paid by the issuer on the securities loaned and would also receive compensation
from investment of the collateral.  A Fund would not have the right to vote any
securities having voting rights during the existence of the loan, but a Fund
would call the loan in anticipation of an important vote to be taken among
holders of the securities or the giving or withholding of their consent on a
material matter affecting the investment.  As with other extensions of credit
there are  risks of delay in recovering, or even loss of rights in, the
collateral should the borrower of the securities fail financially.  However, the
loans would be made only to firms deemed by the applicable Investment Adviser to
be of good standing, and when, in the judgment of the applicable Investment
Adviser, the consideration which can be earned currently from securities loans
of this type justifies the attendant risk. If an Investment Adviser determines
to make securities loans, it is intended that the value of the securities loaned
would not exceed one-third of the value of the total assets of each Fund
(including the loan collateral).

Restricted and Illiquid Securities

     Each Fund may purchase securities that are not registered or that are
offered in an exempt non-public offering ("Restricted Securities") under the
Securities Act of 1933, as amended ("1933 Act"), including securities eligible
for resale to "qualified institutional buyers" pursuant to Rule 144A under the
1933 Act. However, a Fund will not invest more than 15% of its net assets in
illiquid investments, which include repurchase agreements with a notice or
demand period of more than seven days, certain SMBS, municipal leases, certain
over-the-counter options, securities that are not readily marketable and
Restricted Securities, unless the Board of Trustees determines, based upon a
continuing review of the trading markets for the specific Restricted Securities,
that such Restricted Securities are liquid. Certain commercial paper issued in
reliance on Section 4(2) of the 1933 Act is treated like Rule 144A Securities.
The Trustees have adopted guidelines and delegated to the Investment Advisers
the daily function of determining and monitoring the liquidity of the Funds'
portfolio securities. This investment practice could have the effect of
increasing the level of illiquidity in a Fund to the extent that qualified
institutional buyers become for a time uninterested in purchasing these
Restricted Securities.

     The purchase price and subsequent valuation of Restricted Securities may
reflect a discount from the price at which such securities trade when they are
not restricted, since the restriction make them less liquid.  The amount of the
discount from the prevailing market price is expected to vary depending upon the
type of security, the character of the issuer, the party who will bear the
expenses of registering the Restricted Securities and prevailing supply and
demand conditions.

When-Issued and Forward Commitment Securities

     Each Fund may purchase securities on a when-issued basis or purchase or
sell securities on a forward commitment basis.  These transactions involve a
commitment by a Fund to purchase or sell securities at a future date.  The price
of the underlying securities (usually expressed in terms of yield) and the date
when the securities will be delivered and paid for (the settlement date) are
fixed at the time the transaction is negotiated.  When-issued purchases and
forward commitment transactions are negotiated directly with the other party,
and such commitments are not traded on exchanges.  The Funds will purchase
securities on a when-issued basis or purchase or sell securities on a forward
commitment basis only with the intention of completing the transaction and
actually purchasing or selling the securities.  If deemed advisable as a matter
of investment strategy, however, the Funds may dispose of or negotiate a
commitment after entering into it.  A Fund may also sell securities it has
committed to purchase before those securities are delivered to the Fund on the
settlement date.  The Funds may realize a capital gain or loss in connection
with these  transactions.  For purposes of determining each Fund's duration,
the maturity of when-issued or forward commitment securities will be calculated
from the commitment date. Each Fund is required to segregate, until three days
prior to settlement date, cash and liquid assets in an amount sufficient to meet
the purchase price.  Alternatively, each Fund may enter into offsetting
contracts for the forward sale of other securities that it owns. Securities
purchased or sold on a when-issued or forward commitment basis involve a risk of
loss if the value of the security to be purchased declines prior to the
settlement date or if the value of the security to be sold increases prior to
the settlement date.

                                      B-53
<PAGE>
 
Other Investment Companies

     Each Fund reserves the right to invest up to 10% of its total assets,
calculated at the time of purchase, in the securities of other investment
companies, but may not invest more than 5% of its total assets in the securities
of any one investment company or acquire more than 3% of the voting securities
of any other investment company.  Pursuant to an exemptive order obtained from
the SEC, the Funds may invest in money market funds for which the Investment
Adviser or any of its affiliates serves as Investment Adviser.  A Fund will
indirectly bear its proportionate share of any management fees and other
expenses paid by investment companies in which it invests in addition to the
advisory and administration fees paid by the Fund.  However, to the extent that
a Fund invests in a money market fund for which the Investment Adviser or any of
its affiliates acts as Investment Adviser, the management fees payable by the
Fund to the Investment Adviser will be reduced by an amount equal to the Fund's
proportionate share of the management fees paid by such money market fund to the
Investment Adviser or its affiliates.

     Core Fixed Income, Global Income and High Yield Funds may also purchase
shares of investment companies investing primarily in foreign securities,
including "country funds."  Country Funds have portfolios consisting primarily
of securities of issuers located in one foreign country or region.  Core Fixed
Income, Global Income and High Yield Funds may invest in World Equity Benchmark
Shares ("Web") and similar securities that invest in securities included in
foreign securities indices.

Repurchase Agreements

     Each Fund may enter into repurchase agreements with selected broker-
dealers, banks or other financial institutions. A repurchase agreement is an
arrangement under which a Fund purchases securities and the seller agrees to
repurchase the securities within a particular time and at a specified price.
Custody of the securities is maintained by each Fund's custodian. The repurchase
price may be higher than the purchase price, the difference being income to a
Fund, or the purchase and repurchase prices may be the same, with interest at a
stated rate due to a Fund together with the repurchase price on repurchase. In
either case, the income to a Fund is unrelated to the interest rate on the
security subject to the repurchase agreement.

     For purposes of the Act and, generally for tax purposes, a repurchase
agreement is deemed to be a loan from a Fund to the seller of the security.  For
other purposes, it is not clear whether a court would consider the security
purchased by a Fund subject to a repurchase agreement as being owned by a Fund
or as being collateral for a loan by a Fund to the seller.  In the event of
commencement of bankruptcy or insolvency proceedings with respect to the seller
of the security before repurchase of the security under a repurchase agreement,
a Fund may encounter delay and incur costs before being able to sell the
security.  Such a delay may involve loss of interest or a decline in price of
the security. If the court characterizes the transaction as a loan and a Fund
has not perfected a security interest in the security, the Fund may be required
to return the security to the seller's estate and be treated as an unsecured
creditor of the seller.  As an unsecured creditor, a Fund would be at risk of
losing some or all of the principal and interest involved in the transaction.

                                      B-54
<PAGE>
 
     The applicable Investment Adviser seeks to minimize the risk of loss from
repurchase agreements by analyzing the creditworthiness of the obligor, in this
case the seller of the security.  Apart from the risk of bankruptcy or
insolvency proceedings, there is also the risk that the seller may fail to
repurchase the security. However, if the market value of the security subject to
the repurchase agreement becomes less than the repurchase price (including
accrued interest), each Fund will direct the seller of the security to deliver
additional securities so that the market value of all securities subject to the
repurchase agreement equals or exceeds the repurchase price.  Certain repurchase
agreements which provide for settlement in more than seven days can be
liquidated before the nominal fixed term on seven days or less notice.  Such
repurchase agreements will be regarded as liquid instruments.

     In addition, the Funds, together with other registered investment companies
having management agreements with the Investment Advisers or their affiliates,
may transfer uninvested cash balances into a single joint account, the daily
aggregate balance of which will be invested in one or more repurchase
agreements.

Reverse Repurchase Agreements

      Each Fund may borrow money for investment purposes by entering into
transactions called reverse repurchase agreements. Under these arrangements, a
Fund will sell portfolio securities to dealers in U.S. Government Securities or
members of the Federal Reserve System, with an agreement to repurchase the
security on an agreed date, price and interest payment.  Core Fixed Income,
Global Income and High Yield Funds may also enter into reverse repurchase
agreements involving certain foreign government securities.  Reverse repurchase
agreements involve the possible risk that the value of portfolio securities a
Fund relinquishes may decline below the price a Fund must pay when the
transaction closes. Borrowings may magnify the potential for gain or loss on
amounts invested resulting in an increase in the speculative character of a
Fund's outstanding shares.

     When a Fund enters into a reverse repurchase agreement, it places in a
separate custodial account either liquid assets or other high grade debt
securities that have a value equal to or greater than the repurchase price. The
account is then continuously monitored by the Investment Adviser to make sure
that an appropriate value is maintained. Reverse repurchase agreements are
considered to be borrowings under the act.

Non-Diversified Status

     Since Global Income Fund is "non-diversified" under the Act, it is subject
only to certain federal tax diversification requirements.  Under federal tax
laws, Global Income Fund may, with respect to 50% of its total assets, invest up
to 25% of its total assets in the securities of any issuer (except that this
limitation does not apply to U.S. Government Securities).  With respect to the
remaining 50% of the fund's total assets, (1) the Fund may not invest more than
5% of its total assets in the securities of any one issuer (other than the U.S.
Government), and (2) the Fund may not acquire more than 10% of the outstanding
voting securities of any one issuer.  These tests apply 

                                      B-55
<PAGE>
 
at the end of each quarter of its taxable year and are subject to certain
conditions and limitations under the Code.

Portfolio Turnover

     Each Fund may engage in active short-term trading to benefit from yield
disparities among different issues of securities or among the markets for fixed-
income securities, or for other reasons.  it is anticipated that the portfolio
turnover rate of each Fund will vary from year to year.

                                 INVESTMENT RESTRICTIONS

     The following investment restrictions have been adopted by the Trust as
fundamental policies that cannot be changed without the affirmative vote of the
holders of a majority of the outstanding voting securities (as defined in the
Act) of the affected Fund. The investment objective of each Fund and all other
investment policies or practices of the Funds, except for Short Duration Tax-
Free Fund's and Municipal Income Fund's policy to invest under normal market
conditions 80% of their respective net assets in Municipal Securities, are
considered by the Trust not to be fundamental and accordingly may be changed
without shareholder approval.  As defined in the Act, "a majority of the
outstanding voting securities" of a Fund means the vote (a) of 67% or more of
the shares of the Trust or a Fund present at a meeting, if the holders of more
than 50% of the outstanding shares of the Trust or a Fund are present or
represented by proxy or, (b) more than 50% of the shares of the Trust or a Fund.

     For the purposes of the limitations (except for the asset coverage
requirement with respect to borrowings), any limitation which involves a maximum
percentage shall not be considered violated unless an excess over the percentage
occurs immediately after, and is caused by, an acquisition or encumbrance of
securities or assets of, or borrowings by, a Fund.  With respect to the Tax
Exempt Funds, the identification of the issuer of a Municipal Security that is
not a general obligation is made by the Investment Adviser based on the
characteristics of the Municipal Security, the most important of which is the
source of funds for the payment of principal and interest on such securities.

                                      B-56
<PAGE>
 
As a matter of fundamental policy, a Fund may not:

     (1)    Make any investment inconsistent with the Fund's classification as a
            diversified company under the Act. This restriction does not,
            however, apply to any Fund classified as a non-diversified company
            under the Act;

     (2)    Invest more than 25% of its total assets in the securities of one or
            more issuers conducting their principal business activities in the
            same industry (excluding the U.S. government or its agencies or
            instrumentalities). (For the purposes of this restriction, state and
            municipal governments and their agencies, authorities and
            instrumentalities are not deemed to be industries; telephone
            companies are considered to be a separate industry from water, gas
            or electric utilities; personal credit finance companies and
            business credit finance companies are deemed to be separate
            industries; and wholly-owned finance companies are considered to be
            in the industry of their parents if their activities are primarily
            related to financing the activities of their parents.)  This
            restriction does not apply to investments in municipal securities
            which have been pre-refunded by the use of obligations of the U.S.
            government or any of its agencies or instrumentalities. Each of the
            Municipal Income and Short Duration Tax-Free Funds may invest 25% or
            more of the value of its total assets in Municipal Securities which
            are related in such a way that an economic, business or political
            development or change affecting one municipal security would also
            affect the other Municipal Securities. These Municipal Securities
            include (a) Municipal Securities, the interest on which is paid
            solely from revenues of similar projects such as hospitals, electric
            utility systems, multi-family housing, nursing homes, commercial
            facilities (including hotels), steel companies or life care
            facilities; (b) Municipal Securities whose issuers are in the same
            state; and (c) industrial development obligations;

     (3)    Borrow money, except (a) the Fund may borrow from banks (as defined
            in the Act) or through reverse repurchase agreements in amounts up
            to 33 1/3% of its total assets (including the amount borrowed); (b)
            the Fund may, to the extent permitted by applicable law, borrow up
            to an additional 5% of its total assets for temporary purposes; (c)
            the Fund may obtain such short-term credits as may be necessary for
            the clearance of purchases and sales of portfolio securities; (d)
            the Fund may purchase securities on margin to the extent permitted
            by applicable law; and (e) the Fund may engage in transactions in
            mortgage dollar rolls which are accounted for as financings;

     (4)    Make loans, except through (a) the purchase of debt obligations in
            accordance with the Fund's investment objective and policies; (b)
            repurchase agreements with banks, brokers, dealers and other
            financial institutions; and (c) loans of securities as permitted by
            applicable law;

     (5)    Underwrite securities issued by others, except to the extent that
            the sale of portfolio securities by the Fund may be deemed to be an
            underwriting;

                                      B-57
<PAGE>
 
     (6)(a) For each Fund other than Core Fixed Income Fund, purchase, hold or
            deal in real estate, although a Fund may purchase and sell
            securities that are secured by real estate or interests therein,
            securities of real estate investment trusts and mortgage-related
            securities and may hold and sell real estate acquired by a Fund as a
            result of the ownership of securities;

     (6)(b) In the case of Core Fixed Income Fund, purchase, hold or deal in
            real estate (including real estate limited partnerships) or oil, gas
            or mineral leases, although the Fund may purchase and sell
            securities that are secured by real estate or interests therein, may
            purchase mortgage-related securities and may hold and sell real
            estate acquired by the Fund as a result of the ownership of
            securities;

     (7)    Invest in commodities or commodity contracts, except that the Fund
            may invest in currency and financial instruments and contracts that
            are commodities or commodity contracts; and

     (8)    Issue senior securities to the extent such issuance would violate
            applicable law.

     Notwithstanding any other fundamental investment restriction or policy,
each Fund may invest some or all of its assets in a single open-end investment
company or series thereof with substantially the same fundamental investment
objective, restrictions and policies as the Fund.

     In addition to the fundamental policies mentioned above, the Trustees have
adopted the following non-fundamental policies which can be changed or amended
by action of the Trustees without approval of shareholders.

A Fund may not:

     (1)    Invest in companies for the purpose of exercising control or
            management;

     (2)    Invest more than 15% of the Fund's net assets in illiquid
            investments, including repurchase agreements maturing in more than
            seven days, securities which are not readily marketable and
            restricted securities not eligible for resale pursuant to Rule 144A
            under the 1933 Act;

     (3)    Purchase additional securities if the Fund's borrowings (excluding
            covered mortgage dollar rolls) exceed 5% of its net assets; or

     (4)    Make short sales of securities, except short sales against-the-box.

                              Investment Advisers
                              -------------------

     GSAM, One New York Plaza, New York, New York 10004, a separate operating
division of Goldman Sachs, serves as the Investment Adviser to Short Duration
Tax-Free Fund, Government Income Fund, Municipal Income Fund, Core Fixed Income
and High Yield Fund pursuant to a Management Agreement. GSFM, One New York
Plaza, New York, New York 10004, serves as the Investment Adviser to Adjustable
Rate Government Fund and Short Duration Government Fund pursuant to a Management
Agreement.  GSFM, a Delaware limited partnership, is an affiliate of Goldman
Sachs.  GSAMI, 133 Peterborough Court, London EC4A 2BB, England, serves as
Investment Adviser to Global Income Fund pursuant to a Management Agreement. As
a company with unlimited liability under the laws of England, GSAMI is regulated
by the Investment Management Regulatory Organization Limited, a United Kingdom
self-regulatory organization, in the conduct of its investment advisory
business.  GSAMI is also an affiliate of Goldman Sachs.  See "Service Providers"
in the Funds' Prospectuses for a description of the applicable Investment
Adviser's duties as Investment Adviser.  Goldman Sachs has agreed to permit the
Funds to use the name "Goldman Sachs" or a derivative thereof as part of each
Fund's name for as long as a Fund's Management Agreement is in effect.

     Founded in 1869, Goldman Sachs is among the oldest and largest investment
banking firms in the United States.  Goldman Sachs is a leader in developing
portfolio strategies and in many fields of investing and financing,
participating in financial markets worldwide and serving individuals,
institutions, corporations and governments.  Goldman Sachs also is among the
principal market sources for current and thorough information on companies,
industrial sectors, markets, 

                                      B-68
<PAGE>
 
economies and currencies, and trades and makes markets in a wide range of equity
and debt securities 24 hours a day. The firm is headquartered in New York and
has offices throughout the United States and in Beijing, Brazil, Frankfurt,
George Town, Hong Kong, London, Madrid, Mexico City, Milan, Montreal, Osaka,
Paris, Sao Paulo, Seoul, Shanghai, Singapore, Sydney, Taipei, Tokyo, Toronto,
Vancouver and Zurich. It has trading professionals throughout the United States,
as well as in London, Tokyo, Hong Kong and Singapore. The active participation
of Goldman Sachs in the world's financial markets enhances its ability to
identify attractive investments.

     The Investment Advisers are able to draw on the substantial research and
market expertise of Goldman Sachs, whose investment research effort is one of
the largest in the industry. The Goldman Sachs Global Investment Research
Department covers approximately 2,200 companies, including approximately 1,000
U.S. corporations in 60 industries. The in-depth information and analyses
generated by Goldman Sachs' research analysts are available to the Investment
Advisers. The Investment Advisers manage money for some of the world's largest
institutional investors.

     For more than a decade, Goldman Sachs has been among the top-ranked firms
in Institutional Investor's annual "All-America Research Team" survey.  In
addition, many of Goldman Sachs' economists, securities analysts, portfolio
strategists and credit analysts have consistently been highly ranked in
respected industry surveys conducted in the United States and abroad.  Goldman
Sachs is also among the leading investment firms using quantitative analytics
(now used by a growing number of investors) to structure and evaluate
portfolios.  For example, Goldman Sachs' options evaluation model analyzes each
security's term, coupon and call option, providing an overall analysis of the
security's value relative to its interest risk.

     In planning the Tax Exempt Funds' strategies, the portfolio managers also
evaluate and monitor individual issues by using analytical techniques that have
traditionally been applied to corporate bonds and Mortgage-Backed Securities.
In particular, the Investment Adviser's embedded option valuation model provides
a picture of an individual security's relative value and the portfolio's overall
interest rate risk.  By constantly reviewing the positions of securities within
the portfolio, the Investment Adviser looks for opportunities to enhance the Tax
Exempt Funds' yields by fine-tuning the portfolio, using quantitative tools
designed for municipal portfolio management. The Investment Adviser, which
managed approximately $4.55 billion in tax-free securities in 1998, has
assembled an experienced team of professionals for selection of the Tax Exempt
Funds' portfolio securities.

     In structuring Adjustable Rate Government Fund's and Short Duration
Government Fund's respective securities portfolio, the Investment Adviser will
review the existing overall economic and mortgage market trends.  The Investment
Adviser will then study yield spreads, the implied volatility and the shape of
the yield curve.  The Investment Adviser will then apply this analysis to a list
of eligible securities that meet the respective Fund's investment guidelines.
With respect to Adjustable Rate Government Fund, this analysis is used to plan a
two-part portfolio, which will consist of a core portfolio of ARMs and a
"relative value" portfolio of other mortgage assets that can enhance portfolio
returns and lower risk (such as investments in CMO floating-rate tranches and
interest only SMBS).

                                      B-69
<PAGE>
 
     With respect to Adjustable Rate Government Fund, Short Duration Government
Fund, Government Income Fund, Core Fixed Income Fund and High Yield Fund, the
applicable Investment Adviser expects to utilize Goldman Sachs' sophisticated
option-adjusted analytics to help make strategic asset allocations within the
markets for U.S. Government, Mortgage-Backed Securities and other securities and
to employ this technology periodically to re-evaluate the Funds' investments as
market conditions change. Goldman Sachs has also developed a prepayment model
designed to estimate mortgage prepayments and cash flows under different
interest rate scenarios.  Because a Mortgage-Backed Security incorporates the
borrower's right to prepay the mortgage, the Investment Adviser uses a
sophisticated option-adjusted spread (OAS) model to measure expected returns. A
security's OAS is a function of the level and shape of the yield curve,
volatility and the applicable Investment Adviser's expectation of how a change
in interest rates will affect prepayment levels.  Since the OAS model assumes a
relationship between prepayments and interest rates, the Investment Adviser
considers it a better way to measure a security's expected return and absolute
and relative values than yield to maturity. In using OAS technology, the
Investment Adviser will first evaluate the absolute level of a security's OAS,
considering its liquidity and its interest rate, volatility and prepayment
sensitivity. The Investment Adviser will then analyze its value relative to
alternative investments and to its own investments. The Investment Adviser will
also measure a security's interest rate risk by computing an option adjusted
duration (OAD).  The Investment Adviser believes a security's OAD is a better
measurement of its price sensitivity than cash flow duration, which
systematically misstates portfolio duration. The Investment Adviser also
evaluates returns for different mortgage market sectors and evaluates the credit
risk of individual securities. This sophisticated technical analysis allows the
Investment Adviser to develop portfolio and trading strategies using Mortgage-
Backed Securities that are believed to be superior investments on a risk-
adjusted basis and which provide the flexibility to meet the respective Fund's
duration targets and cash flow pattern requirements.

     Because the OAS is adjusted for the differing characteristics of the
underlying securities, the OAS of different Mortgage-Backed Securities can be
compared directly as an indication of their relative value in the market.  The
Investment Adviser also expects to use OAS-based pricing methods to calculate
projected security returns under different, discrete interest rate scenarios,
and Goldman Sachs' proprietary prepayment model to generate yield estimates
under these scenarios.  The OAS, scenario returns, expected returns, and yields
of securities in the mortgage market can be combined and analyzed in an optimal
risk-return matching framework.

     The Investment Adviser will use OAS analytics to choose what they believe
is an appropriate portfolio of investments for Adjustable Rate Government Fund,
Short Duration Government Fund, Government Income Fund and Core Fixed Income
Fund from a universe of eligible investments.  In connection with initial
portfolio selections, in addition to using OAS analytics as an aid to meeting
each Fund's particular composition and performance targets, the Investment
Adviser will also take into account important market criteria like the available
supply and relative liquidity of various mortgage securities in structuring the
portfolio.

     The Investment Adviser also expects to use OAS analytics to evaluate the
mortgage market on an ongoing basis.  Changes in the relative value of various
Mortgage-Backed Securities could 

                                      B-70
<PAGE>
 
suggest tactical trading opportunities for the Funds. The Investment Adviser
will have access to both current market analysis as well as historical
information on the relative value relationships among different Mortgage-Backed
Securities. Current market analysis and historical information is available in
the Goldman Sachs database for most actively traded Mortgage-Backed Securities.

     Goldman Sachs has agreed to provide the Investment Adviser, on a non-
exclusive basis, use of its mortgage prepayment model, OAS model and any other
proprietary services which it now has or may develop, to the extent such
services are made available to other similar customers.  Use of these services
by the Investment Advisers with respect to a Fund does not preclude Goldman
Sachs from providing these services to third parties or using such services as a
basis for trading for its own account or the account of others.

     The fixed-income research capabilities of Goldman Sachs available to the
Investment Advisers include the Goldman Sachs Fixed Income Research Department
and the Credit Department.  The Fixed Income Research Department monitors
developments in U.S. and foreign fixed-income markets, assesses the outlooks for
various sectors of the markets and provides relative value comparisons, as well
as analyzes trading opportunities within and across market sectors. The Fixed
Income Research Department is at the forefront in developing and using computer-
based tools for analyzing fixed-income securities and markets, developing new
fixed-income products and structuring portfolio strategies for investment policy
and tactical asset allocation decisions.  The Credit Department tracks specific
governments, regions and industries and from time to time may review the credit
quality of a Fund's investments.

     In addition to fixed-income research and credit research, the Investment
Adviser, in managing Global Income Fund, is supported by Goldman Sachs'
economics research.  The Economics Research Department, based in London,
conducts economic, financial and currency markets research which analyzes
economic trends and interest and exchange rate movements worldwide.  The
Economics Research Department tracks factors such as inflation and money supply
figures, balance of trade figures, economic growth, commodity prices, monetary
and fiscal policies, and political events that can influence interest rates and
currency trends.  The success of Goldman Sachs' international research team has
brought wide recognition to its members.  The team has earned top rankings in
various external surveys such as Extel, Institutional Investor and Reuters.
These rankings acknowledge the achievements of the firm's economists,
strategists and equity analysts.

     In allocating assets in Global Income Fund's portfolio among currencies,
the Investment Adviser will have access to the Global Asset Allocation Model.
The model is based on the observation that the prices of all financial assets,
including foreign currencies, will adjust until investors globally are
comfortable  holding the pool of outstanding assets.  Using the model, the
Investment Adviser will estimate the total returns from each currency sector
which are consistent with the average investor holding a portfolio equal to the
market capitalization of the financial assets among those currency sectors.
These estimated equilibrium returns are then combined with the expectations of
Goldman Sachs' professionals expectations to produce an optimal currency and
asset allocation for the level of risk suitable for the Fund's investment
objective and criteria.

     The Management Agreements provide that GSAM, GSFM and GSAMI, in their
capacity as Investment Advisers may each render similar services to others so
long as the services under the Management Agreements are not impaired thereby.
The Management Agreements were most recently approved by the Trustees of the
Trust, including a majority of the Trustees of the Trust who are not parties to
such agreements or "interested persons" (as such term is defined in the Act) of
any party thereto (the "non-interested Trustees"), on April 22, 1998.  The
applicable Fund's Management Agreement was approved by the shareholders of
Adjustable Rate Government Fund on October 30, 1991, the shareholders of Short
Duration Government Fund on March 27, 1989, the sole initial shareholder of
Short Duration Tax-Free Fund on September 25, 1992, the sole initial shareholder
of Core Fixed Income Fund on October 29, 1993, and the shareholders of each
other Fund on April 21, 1997.  Each Management Agreement will remain in effect
until June 30, 1999 and will continue in effect with respect to the applicable
Fund from year to year thereafter provided such continuance is specifically
approved at least annually by (a) the vote of a majority of the outstanding
voting securities of such Fund or a majority of the Trustees of the Trust, and
(b) the vote of a majority of the non-interested Trustees of the Trust; cast in
person at a meeting called for the purpose of voting on such approval.

     Each Management Agreement will terminate automatically if assigned (as
defined in the Act).  Each Management Agreement is also terminable at any time
without penalty by the Trustees of the Trust or by vote of a majority of the
outstanding voting securities of a Fund on 60 days' written notice to the
applicable Investment Adviser or by the Investment Adviser on 60 days' written
notice to the Trust.

     Pursuant to the Management Agreements, the Investment Advisers are entitled
to receive the fees set forth below, payable monthly based on such Fund's
average daily net assets.  In addition, as of the date of this Additional
Statement the Investment Advisers are voluntarily limiting their management fees
for certain Funds to the annual rates also listed below:

     With respect to Government Income, Municipal Income and Global Income
Funds, a Management Agreement combining both advisory and administration
services (and subadvisory services in the case of Global Income Fund) was
adopted effective April 30, 1997.  The Management Agreements for the other Funds
previously combined such services.  The contractual rate set forth in the table
is the rate payable under the Management Agreements (and, in the case of
Government Income, Municipal Income and Global Income Funds, is identical to the
aggregate advisory, subadvisory and administration fee rate payable by such
Funds under the previously separate investment advisory, subadvisory and
administration agreements).

     For the fiscal years ended October 31, 1998, 1997, and 1996, the amounts of
the investment advisory and administration fees incurred by each Fund then in
existence were as follows:

     Each Investment Adviser performs administrative services for the applicable
Funds under the Management Agreement. Such administrative services include,
subject to the general supervision of the Trustees of the Trust, (a) providing
supervision of all aspects of the Funds' non-investment operations (other than
certain operations performed by others pursuant to agreements with the Funds);
(b) providing the Funds, to the extent not provided pursuant to the agreement
with the Trust's custodian, transfer and dividend disbursing agent or agreements
with other institutions, with personnel to perform such executive,
administrative and clerical services as are reasonably necessary to provide
effective administration of the Funds; (c) arranging, to the extent not provided
pursuant to such agreements, for the preparation, at the Funds' expense, of each
Fund's tax returns, reports to shareholders, periodic updating of the Funds'
prospectuses and statements of additional information, and reports filed with
the SEC and other regulatory authorities; (d) providing the Funds, to the extent
not provided pursuant to such agreements, with adequate office space and certain
related office equipment and services; and (e) maintaining all of the Funds'
records other than those maintained pursuant to such agreements.

     Activities of Goldman Sachs and Its Affiliates and Other Accounts Managed
     -------------------------------------------------------------------------
by Goldman Sachs.  The involvement of the Investment Adviser and Goldman Sachs
- ----------------                                                              
and their affiliates, in the management of, or their interest in, other accounts
and other activities of Goldman Sachs may present conflicts of interest with
respect to the Funds or impede their investment activities.

     Goldman Sachs and its affiliates, including, without limitation, the
Investment Advisers and their advisory affiliates have proprietary interests in,
and may manage or advise with respect to, accounts or funds (including separate
accounts and other funds and collective investment vehicles) which have
investment objectives similar to those of the Funds and/or which engage in
transactions in the same types of securities, currencies and instruments as the
Funds.  Goldman Sachs and its affiliates are major participants in the global
currency, equities, swap and fixed-income markets, in each case both on a
proprietary basis and for the accounts of customers. As such, Goldman Sachs and
its affiliates are actively engaged in transactions in the same securities,
currencies, and instruments in which the Funds invest. Such activities could
affect the prices and availability of the securities, currencies, and
instruments in which the Funds invest, which could have an adverse impact on
each Fund's performance. Such transactions, particularly in respect of
proprietary accounts or customer accounts other than those included in the
Investment Advisers' and their advisory affiliates' asset management activities,
will be executed independently of the Funds' transactions and thus at prices or
rates that may be more or less favorable.  When the Investment Advisers and
their advisory affiliates seek to purchase or sell the same assets for their
managed accounts, including the Funds, the assets actually purchased or sold may
be allocated among the accounts on a basis determined in its good faith
discretion of such entitles to be equitable.  In some cases, this system may
adversely affect the size or the price of the assets purchased or sold for the
Funds.

     From time to time, the Funds' activities may be restricted because of
regulatory restrictions applicable to Goldman Sachs and its affiliates, and/or
their internal policies designed to comply with such restrictions.  As a result,
there may be periods, for example, when the Investment Advisers, and/or their
affiliates, will not initiate or recommend certain types of transactions in
certain 

                                      B-74
<PAGE>
 
securities or instruments with respect to which the Investment Advisers
and/or their affiliates are performing services or when position limits have
been reached.

     In connection with their management of the Funds, the Investment Advisers
may have access to certain fundamental analysis and proprietary technical models
developed by Goldman Sachs and other affiliates.  The Investment Advisers will
not be under any obligation, however, to effect transactions on behalf of the
Funds in accordance with such analysis and models.  In addition, neither Goldman
Sachs nor any of its affiliates will have any obligation to make available any
information regarding their proprietary activities or strategies, or the
activities or strategies used for other accounts managed by them, for the
benefit of the management of the Funds and it is not anticipated that the
Investment Advisers will have access to such information for the purpose of
managing the Funds. The proprietary activities or portfolio strategies of
Goldman Sachs and its affiliates or the activities or strategies used for
accounts managed by them or other customer accounts could conflict with the
transactions and strategies employed by the Investment Advisers in managing the
Funds.

     The results of each Fund's investment activities may differ significantly
from the results achieved by the Investment Advisers and their affiliates for
their proprietary accounts or accounts (including investment companies or
collective investment vehicles) managed or advised by them.  It is possible that
Goldman Sachs and its affiliates and such other accounts will achieve investment
results which are substantially more or less favorable than the results achieved
by a Fund.  Moreover, it is possible that a Fund will sustain losses during
periods in which Goldman Sachs and its affiliates achieve significant profits on
their trading for proprietary or other accounts.  The opposite result is also
possible.

     The investment activities of Goldman Sachs and its affiliates for their
proprietary accounts and accounts under their management may also limit the
investment opportunities for the Funds in certain emerging markets in which
limitations are imposed upon the aggregate amount of investment, in the
aggregate or individual issuers, by affiliated foreign investors.

     An investment policy committee which may include partners of Goldman Sachs
and its affiliates may develop general policies regarding a Fund's activities,
but will not be involved in the day-to-day management of such Fund.  In such
instances, those individuals may, as a result, obtain information regarding the
Fund's proposed investment activities which is not generally available to the
public.  In addition, by virtue of their affiliation with Goldman Sachs, any
such member of an investment policy committee will have direct or indirect
interests in the activities of Goldman Sachs and its affiliates in securities,
currencies and investments similar to those in which the Fund invests.

     In addition, certain principals and certain employees of the Investment
Advisers are also principals or employees of Goldman Sachs or their affiliated
entities.  As a result, the performance by these principals and employees of
their obligations to such other entities may be a consideration of which
investors in the Funds should be aware.

     The Investment Advisers may enter into transactions and invest in
instruments and, in the case of Core Fixed Income, Global Income and High Yield
Funds, currencies on behalf of the 

                                      B-75
<PAGE>
 
applicable Funds in which customers of Goldman Sachs serve as the counterparty,
principal or issuer. In such cases, such party's interests in the transaction
will be adverse to the interests of the Funds, and such party may have no
incentive to assure that the Funds obtain the best possible prices or terms in
connection with the transactions. Goldman Sachs and its affiliates may also
create, write or issue derivative instruments for customers of Goldman Sachs or
its affiliates, the underlying securities currencies or instruments of which may
be those in which the Funds invest or which may be based on the performance of a
Fund. The Funds may, subject to applicable law, purchase investments which are
the subject of an underwriting or other distribution by Goldman Sachs or its
affiliates and may also enter into transactions with other clients of Goldman
Sachs or its affiliates where such other clients have interests adverse to those
of the Funds. At times, these activities may cause departments of Goldman Sachs
or its affiliates to give advice to clients that may cause these clients to take
actions adverse to the interests of the client. To the extent affiliated
transactions are permitted, the Funds will deal with Goldman Sachs and its
affiliates on an arms-length basis.

     Each Fund will be required to establish business relationships with its
counterparties based on the Fund's own credit standing. Neither Goldman Sachs
nor its affiliates will have any obligation to allow their credit to be used in
connection with a Fund's establishment of its business relationships, nor is it
expected that a Fund's counterparties will rely on the credit of Goldman Sachs
or any of its affiliates in evaluating the Fund's creditworthiness.

     From time to time, Goldman Sachs or any of its affiliates may, but is not
required to, purchase and hold shares of a Fund in order to increase the assets
of the Fund.  Increasing a Fund's assets may enhance investment flexibility and
diversification and may contribute to economies of scale that tend to reduce a
Fund's expense ratio.  Goldman Sachs reserves the right to redeem at any time
some or all of the shares of a Fund acquired for its own account.  A large
redemption of shares of a Fund by Goldman Sachs could significantly reduce the
asset size of the Fund, which might have an adverse effect on the Fund's
investment flexibility, portfolio diversification and expense ratio.  Goldman
Sachs will consider the effect of redemptions on a Fund and other shareholders
in deciding whether to redeem its shares.

     It is possible that a Fund's holding will include securities of entities
for which Goldman Sachs performs investment banking services as well as
securities of entities in which Goldman Sachs makes a market.  From time to
time, Goldman Sachs' activities may limit the Funds' flexibility in purchases
and sales of securities.  When Goldman Sachs is engaged in and underwriting or
other distribution of securities of an entity, the Funds' investment advisers
may be prohibited from purchasing or recommending the purchase of certain
securities of that entity for the Funds.

Distributor and Transfer Agent
- ------------------------------

     Goldman Sachs serves as the exclusive distributor of shares of the Funds
pursuant to a "best efforts" arrangement as provided by a distribution agreement
with the Trust. Shares of the Funds are offered and sold on a continuous basis
by Goldman Sachs, acting as agent.  Pursuant to the distribution agreement,
after the Funds' Prospectuses and periodic reports have been prepared, set in
type and mailed to shareholders, Goldman Sachs will pay for the printing and
distribution of copies thereof used in connection with the offering to
prospective investors.  Goldman Sachs will also pay 

                                      B-76
<PAGE>
 
for other supplementary sales literature and advertising costs. Goldman Sachs
has entered into sales agreements with certain investment dealers and financial
service firms (the "Authorized Dealers") to solicit subscriptions for Class A,
Class B and Class C Shares of each of the Funds that offer such classes of
shares. Goldman Sachs receives a portion of the sales load imposed on the sale,
in the case of Class A Shares, or redemption in the case of Class B and Class C
Shares, of such Fund shares. No Class C Shares were outstanding during the
fiscal year ended 1996. Goldman Sachs retained approximately the following
combined commissions on sales of Class A, B and C Shares during the following
periods:

     The foregoing distribution and transfer agency agreements each provide that
Goldman Sachs may render similar services to others so long as the services each
provides thereunder to the Funds are not impaired thereby.  Each such agreement
also provides that the Trust will indemnify Goldman Sachs against certain
liabilities.

Expenses
- --------

     The Trust, on behalf of each Fund, is responsible for the payment of each
Fund's respective expenses.  The expenses include, without limitation, the fees
payable to the Investment Adviser, service fees paid to Service Organizations,
the fees and expenses of the Trust's custodian and subcustodians, transfer agent
fees, brokerage fees and commissions, filing fees for the registration or
qualification of the Trust's shares under federal or state securities laws,
expenses of the organization of the Trust, fees and expenses incurred by the
Trust in connection with membership in investment company organizations, taxes,
interest, costs of liability insurance, fidelity bonds or indemnification, any
costs,  expenses or losses arising out of any liability of, or claim for damages
or other relief asserted against, the Trust for violation of any law, legal, tax
and auditing fees and expenses (including the cost of legal and certain
accounting services rendered by employees of Goldman Sachs, or its affiliates,
with respect to the Trust), expenses of preparing and setting in type
Prospectuses, Additional Statements, proxy material, reports and notices and the
printing and distributing of the same to the Trust's shareholders and regulatory
authorities, fees under any distribution and service, administration or service
plans applicable to a particular class, any compensation and expenses of its
"non-interested" Trustees and extraordinary expenses, if any, incurred by the
Trust.  Except for fees under any distribution and service, administration or
service plans applicable to a particular class and transfer agency fees, all
Fund expenses are borne on a non-class specific basis.

     As of the date of this Additional Statement, the Investment Advisers were
voluntarily reducing or otherwise limiting certain "Other Expenses" (excluding
management fees, fees payable under administration, distribution and service
plans, transfer agency fees, taxes, interest, brokerage 

                                      B-78

High Yield(1)                                    0.02%

     Such reductions or limits are calculated monthly on a cumulative basis.
The Investment Advisers may modify or discontinue such expense limitations or
the limitations on the management fees, described above under "Management --
Investment Advisers," in the future at their discretion.  For the fiscal years

(1)  High Yield Fund commenced operations on August 1, 1997.

     Fees and expenses of legal counsel, registering shares of each Fund,
holding meetings and communicating with shareholders may include an allocable
portion of the cost of maintaining an internal legal and compliance department.
Each Fund may also bear an allocable portion of the costs incurred by the
Investment Advisers in performing certain accounting services not being provided
by the Trust's custodian.

Custodian and Sub-Custodians
- ----------------------------

     State Street Bank and Trust Company ("State Street"), 1776 Heritage Drive,
North Quincy, Massachusetts 02110, is the custodian of the Trust's portfolio
securities and cash.  State Street also maintains the Trust's accounting
records.  State Street may appoint sub-custodians from time to time 

                                      B-79
<PAGE>
 
to hold certain securities purchased by the Trust in foreign countries and to
hold cash and currencies for the Trust.

Independent Public Accountants
- ------------------------------

     Arthur Andersen LLP, independent public accountants, 225 Franklin Place,
Boston, Massachusetts 02110, have been selected as auditors of the Trust.  In
addition to audit services, Arthur Andersen LLP prepares the Trust's federal and
state tax returns, and provides consultation and assistance on accounting,
internal control and related matters.

                                 PORTFOLIO TRANSACTIONS

     The portfolio transactions for the Funds are generally effected at a net
price without a broker's commission (i.e., a dealer is dealing with a Fund as
principal and receives compensation equal to the spread between the dealer's
cost for a given security and the resale price of such security).  In certain
foreign countries, debt securities in which Core Fixed Income, Global Income and
High Yield Funds may invest are traded on exchanges at fixed commission rates.
In connection with portfolio transactions, the Management Agreement provides
that the Investment Advisers shall attempt to obtain the most favorable
execution and net price available.  The Management Agreement provides that, on
occasions when an Investment Adviser deems the purchase or sale of a security to
be in the best interests of a Fund as well as its other customers (including any
other fund or other investment company or advisory account for which the
Investment Advisers or an affiliate act as Investment Adviser), a Fund, to the
extent permitted by applicable laws and regulations, may aggregate the
securities to be sold or purchased for the Fund with those to be sold or
purchased for such other customers in order to obtain the best net price and
most favorable execution. In such event, allocation of the securities so
purchased or sold, as well as the expenses incurred in the transaction, will be
made by the applicable Investment Adviser in the manner it considers to be most
equitable and consistent with its fiduciary obligations to the  applicable Fund
and such other customers.  In some instances, this procedure may adversely
affect the size and price of the position obtainable for a Fund.  The Management
Agreement permits each Investment Adviser, in its discretion, to purchase and
sell portfolio securities to and from dealers who provide the Trust with
brokerage or research services in which dealers may execute brokerage
transactions at a higher cost to the Fund. Brokerage and research services
furnished by firms through which the Funds effect their securities transactions
may be used by the Investment Adviser in servicing other accounts and not all of
these services may be used by the Investment Advisers in connection with the
specific Fund generating the brokerage credits.  Such research or other services
may include research reports on companies, industries, and securities; economic
and financial data; financial publications; computer data bases; quotation
equipment and services; and research-oriented computer hardware, software and
other services.  The fees received under the Management Agreement are not
reduced by reason of the Investment Adviser receiving such brokerage and
research services.

     Such services are used by the Investment Adviser in connection with all of
its investment activities, and some of such services obtained in connection with
the execution of transactions of a Fund may be used in managing other investment
accounts.  Conversely, brokers furnishing such services may be selected for the
execution of transactions of such other accounts, whose aggregate 

                                      B-80
<PAGE>
 
assets are far larger than those of a Fund, and the services furnished by such
brokers may be used by the Investment Adviser in providing management services
for the Trust.

     In circumstances where two or more broker-dealers offer comparable prices
and execution capability, preference may be given to a broker-dealer which has
sold shares of a Fund as well as shares of other investment companies or
accounts managed by the Investment Adviser.  This policy does not imply a
commitment to execute all portfolio transactions through all broker-dealers that
sell shares of the Fund.

     Subject to the above considerations, the Investment Adviser may use Goldman
Sachs as a broker for a Fund.  In order for Goldman Sachs to effect any
portfolio transactions for a Fund, the commissions, fees or other remuneration
received by Goldman Sachs must be reasonable and fair compared to the
commissions, fees or other remuneration paid to other brokers in connection with
comparable transactions involving similar instruments being purchased or sold on
an exchange during a comparable period of time.  This standard would allow
Goldman Sachs to receive no more than the remuneration which would be expected
to be received by an unaffiliated broker in a commensurate arm's-length
transaction.  Furthermore, the Trustees, including a majority of the Trustees
who are not "interested" Trustees, have adopted procedures which are reasonably
designed to provide that any commissions, fees, or other remuneration paid to
Goldman Sachs are consistent with the foregoing standard.  Brokerage
transactions with Goldman Sachs are also subject to such fiduciary standards as
may be imposed upon Goldman Sachs by applicable law.

                                 SHARES OF THE TRUST

     Each Fund is a series of Goldman Sachs Trust, a Delaware business trust
established by an Agreement and Declaration of Trust dated January 28, 1997.
The Funds were previously series of Goldman Sachs Trust, a Massachusetts
business trust, and were reorganized into the Trust as of April 30, 1997.

     The Trustees have authority under the Trust's Agreement and Declaration of
Trust to create and classify shares of beneficial interest in separate series,
without further action by shareholders.  The Trustees also have authority to
classify and reclassify any series of shares into one or more classes of shares.
The Act requires that where more than one class or series of shares exists, each
class or series must be preferred over all other classes or series in respect of
assets specifically allocated to such class or series.  As of the date of this
Additional Statement, the Trustees have authorized:  (i) the issuance of six
classes of shares of Short Duration Government Fund, Short Duration Tax-Free
Fund and Core Fixed Income Fund:  Institutional Shares, Administration Shares,
Service Shares, Class A Shares, Class B Shares and Class C Shares; the issuance
of five classes of shares of Government Income Fund, Municipal Income Fund,
Global Income Fund and High Yield Fund: Institutional Shares, Service Shares,
Class A Shares, Class B Shares and Class C Shares; and (ii) the issuance of four
classes of shares of Adjustable Rate Government Fund: Institutional Shares,
Administration Shares, Service Shares and Class A Shares.  Additional series may
be added in the future.  As of October 31, 1998, no Class B or C Shares of the
Adjustable Rate Government Fund were outstanding.

     Each Institutional Share, Administration Share, Service Share, Class A
Share, Class B Share and Class C Share of a Fund represents a proportionate
interest in the assets belonging to the applicable class of the Fund.  All
expenses of a Fund are borne at the same rate by each class of shares, except
that fees under Administration and Service Plans are borne exclusively by
Administration and Service Shares, fees under Distribution and Service Plans are
borne exclusively by Class A, Class B or Class C Shares and transfer agency fees
are borne at different rates by Class A, Class B or Class C Shares than
Institutional, Administration and Service Shares.  The Trustees may determine in
the future that it is appropriate to allocate other expenses differently among
classes of shares and may do so to the extent consistent with the rules of the
SEC and positions of the IRS.  Each class of shares may have different minimum
investment requirements and be entitled to different shareholder services.  With
limited exceptions, shares of a class may only be exchanged for shares of the
same or an equivalent class of another series.  See "Shareholder Guide" in the
Prospectus.

     Institutional Shares may be purchased at net asset value without a sales
charge for accounts in the name of an investor or institution that is not
compensated by a Fund for services provided to the institution's customers.

     Administration Shares may be purchased for accounts held in the name of an
institution that provides certain account administration services to its
customers, including maintenance of account records and processing orders to
purchase, redeem and exchange Administration Shares.  Administration Shares bear
the cost of account administration fees at the annual rate of up to 0.25% of the
average daily net assets of such Administration Shares.

     Service Shares may be purchased at net asset value without a sales charge
for accounts held in the name of an institution that, directly or indirectly,
provides certain account administration and shareholder liaison services to its
customers, including maintenance of account records and processing orders to
purchase, redeem and exchange Service Shares.  Service Shares bear the cost of
account administration fees at the annual rate of up to 0.50% of the average
daily net assets of the Fund attributed to Service Shares.

     Class A Shares are sold, with an initial sales charge, through brokers and
dealers who are members of the National Association of Securities Dealers, Inc.
("NASD") and certain other financial service firms that have sales agreements
with Goldman Sachs.  Class A Shares of the Funds bear the cost of distribution
(Rule 12b-1) fees at the aggregate rate of up to 0.25% of the average daily net
assets of such Class A Shares.  With respect to Class A Shares, the Distributor
at its discretion may use compensation for distribution services paid under the
Distribution and Services Plan for personal and account maintenance services and
expenses so long as such total compensation under the Plan does not exceed the
maximum cap on "service fees" imposed by the NASD.

     Class B and Class C Shares of the Funds are sold subject to a contingent
deferred sales charge through brokers and dealers who are members of the NASD
and certain other financial services firms that have sales arrangements with
Goldman Sachs. Class B and Class C Shares bear the cost of distribution (Rule
12b-1) fees at the aggregate rate of up to 0.75% of the average daily 

                                      B-86
<PAGE>
 
net assets attributed to Class B and Class C Shares. Class A (Global Income Fund
only), Class B and Class C Shares also bear the cost of service fees at an
annual rate of up to 0.25% of the average daily net assets attributed to such
Shares.

     It is possible that an institution or its affiliate may offer different
classes of shares (i.e., Institutional, Administration, Service, Class A, Class
B and Class C Shares) to its customers and thus receive different compensation
with respect to different classes of shares of each Fund.  Dividends paid by
each Fund, if any, with respect to each class of shares will be calculated in
the same manner, at the same time on the same day and will be in the same
amount, except for differences caused by the fact that the respective account
administration, service and distribution and service fees relating to a
particular class will be borne exclusively by that class. Similarly, the net
asset value per share may differ depending upon the class of shares purchased.

     Certain aspects of the shares may be altered, after advance notice to
shareholders, if it is deemed necessary in order to satisfy certain tax
regulatory requirements.

     When issued, shares are fully paid and non-assessable.  In the event of
liquidation of a Fund, shareholders of that Fund are entitled to share pro rata
in the net assets of the applicable class of the relevant Fund available for
distribution to such shareholders.  All shares are freely transferable and have
no preemptive, subscription or conversion rights.

     In the interest of economy and convenience, the Trust does not issue
certificates representing the Funds' shares.  Instead, the Transfer Agent
maintains a record of each shareholder's ownership.  Each shareholder receives
confirmation of purchase and redemption orders from the Transfer Agent.  Fund
shares and any dividends and distributions paid by the Funds are reflected in
account statements from the Transfer Agent.

     Rule 18f-2 under the Act provides that any matter required to be submitted
by the provisions of the Act or applicable state law, or otherwise, to the
holders of the outstanding voting securities of an investment company such as
the Trust shall not be deemed to have been effectively acted upon unless
approved by the holders of a majority of the outstanding shares of each class or
series affected by such matter.  Rule 18f-2 further provides that a class or
series shall be deemed to be affected by a matter unless the interests of each
class or series in the matter are substantially identical or the matter does not
affect any interest of such class or series. However, Rule 18f-2 exempts the
selection of independent public accountants, the approval of principal
distribution contracts and the election of trustees from the separate voting
requirements of Rule 18f-2.

     The Trust is not required to hold annual meetings of shareholders and does
not intend to hold such meetings.  In the event that a meeting of shareholders
is held, each share of the Trust will be entitled, as determined by the
Trustees, either to one vote for each share or to one vote for each dollar of
net asset value represented by such shares on all matters presented to
shareholders including the election of Trustees (this method of voting being
referred to as "dollar based voting").  However, to the extent required by the
Act or otherwise determined by the Trustees, series and classes of the Trust
will vote separately from each other.  Shareholders of the Trust do not have
cumulative voting rights in the election of Trustees.  Meetings of shareholders
of the Trust, or any series or class thereof, may be called by the Trustees,
certain officers or upon the written request of holders of 10% or more of the
shares entitled to vote at such meetings.  The Trustees will call a special
meeting of shareholders for the purpose of electing Trustees, if, at any time,
less than a majority of Trustees holding office at the time were elected by
shareholders.  The shareholders of the Trust will have voting rights only with
respect to the limited number of matters specified in the Agreement and
Declaration of Trust and such other matters as the Trustees may determine or may
be required by law.

     The Agreement and Declaration of Trust provides for indemnification of
Trustees, officers and agents of the Trust unless the recipient is adjudicated
(i) to be liable by reason of willful misfeasance, bad faith, gross negligence
or reckless disregard of the duties involved in the conduct of such person's
office; or (ii) not to have acted in good faith in the reasonable belief that
such person's actions were in the best interest of the Trust.  The Agreement and
Declaration of Trust provides that, if any shareholder or former shareholder of
any series is held personally liable solely 

                                      B-88
<PAGE>
 
by reason of being or having been a shareholder and not because of the
shareholder's acts or omissions or for some other reason, the shareholder or
former shareholder (or heirs, executors, administrators, legal representatives
or general successors) shall be held harmless from and indemnified against all
loss and expense arising from such liability. The Trust, acting on behalf of any
affected series, must, upon request by such shareholder, assume the defense of
any claim made against such shareholder for any act or obligation of the series
and satisfy any judgment thereon from the assets of the series.

     The Agreement and Declaration of Trust permits the termination of the Trust
or of any series or class of the Trust (i) by a majority of the affected
shareholders at a meeting of shareholders of the Trust, series or class; or (ii)
by a majority of the Trustees without shareholder approval if the Trustees
determine that such action is in the best interest of the Trust or its
shareholders.  The factors and events that the Trustees may take into account in
making such determination include (i) the inability of the Trust or any
successor series or class to maintain its assets at an appropriate size; (ii)
changes in laws or regulations governing the Trust, series or class or affecting
assets of the type in which it invests; or (iii) economic developments or trends
having a significant adverse impact on their business or operations.

     The Agreement and Declaration of Trust authorizes the Trustees without
shareholder approval to cause the Trust, or any series thereof, to merge or
consolidate with any corporation, association, trust or other organization or
sell or exchange all or substantially all of the property belonging to the Trust
or any series thereof.  In addition, the Trustees, without shareholder approval,
may adopt a master-feeder structure by investing all or a portion of the assets
of a series of the Trust in the securities of another open-end investment
company with substantially the same investment objective, restrictions and
policies.

     The Agreement and Declaration of Trust permits the Trustees to amend the
Declaration of Trust without a shareholder vote.  However, shareholders of the
Trust have the right to vote on any amendment (i) that would affect the voting
rights of shareholders; (ii) that is required by law to be approved by
shareholders; (iii) that would amend the voting provisions of the Declaration of
Trust; or (iv) that the Trustees determine to submit to shareholders.

     The Trustees may appoint separate Trustees with respect to one or more
series or classes of the Trust's shares (the "Series Trustees").  Series
Trustees may, but are not required to, serve as Trustees of the Trust or any
other series or class of the Trust.  The Series Trustees have, to the exclusion
of any other Trustees of the Trust, all the powers and authorities of Trustees
under the Agreement and Declaration of Trust with respect to any other series or
class.

Shareholder and Trustee Liability

     Under Delaware law, the shareholders of the Funds are not generally subject
to liability for the debts or obligations of the Trust. Similarly, Delaware law
provides that a series of the Trust will not be liable for the debts or
obligations of any other series of the Trust. However, no similar statutory or
other authority limiting business trust shareholder liability exists in other
states. As a result, to the extent that a Delaware business trust or a
shareholder is subject to the jurisdiction of 

                                      B-89
<PAGE>
 
courts of such other states, the courts may not apply Delaware law and may
thereby subject the Delaware business trust shareholders to liability. To guard
against this risk, the Agreement and Declaration of Trust contains an express
disclaimer of shareholder liability for acts or obligations of a Fund. Notice of
such disclaimer will normally be given in each agreement, obligation or
instrument entered into or executed by a series or the Trustees. The Agreement
and Declaration of Trust provides for indemnification by the relevant Fund for
all loss suffered by a shareholder as a result of an obligation of the series.
The Agreement and Declaration of Trust also provides that a series shall, upon
request, assume the defense of any claim made against any shareholder for any
act or obligation of the series and satisfy any judgment thereon. In view of the
above, the risk of personal liability of shareholders of a Delaware business
trust is remote.

     In addition to the requirement under Delaware law, the Agreement and
Declaration of Trust provides that shareholders of a series may bring a
derivative action on behalf of the series only if the following conditions are
met: (a) shareholders eligible to bring such derivative action under Delaware
law who hold at least 10% of the outstanding shares of the series, or 10% of the
outstanding shares of the class to which such action relates, shall join in the
request for the Trustees to commence such action; and (b) the Trustees must be
afforded a reasonable amount of time to consider such shareholder request and to
investigate the basis of and to employ other advisers in considering the merits
of the request and shall require an undertaking by the shareholders making such
request to reimburse the Fund for the expense of any such advisers in the event
that the Trustees determine not to bring such action.

     The Agreement and Declaration of Trust further provides that the Trustees
will not be liable for errors of judgment or mistakes of fact or law, but
nothing in the Agreement and Declaration of Trust protects a Trustee against
liability to which he or she would otherwise be subject by reason of willful
misfeasance, bad faith, gross negligence, or reckless disregard of the duties
involved in the conduct of his or her office.

                                 NET ASSET VALUE

     Under the Act, the Trustees of the Trust are responsible for determining in
good faith the fair value of securities of the Funds. In accordance with
procedures adopted by the Trustees of the Trust, the net asset value per share
of each class of each Fund is calculated by determining the value of the net
assets attributable to each class of that Fund and dividing by the number of
outstanding shares of that class.  All securities are valued as of the close of
regular trading on the New York Stock Exchange (normally, but not always, 4:00
p.m. New York time) on each Business Day.  The term "Business Day" means any day
the New York Stock Exchange is open for trading, which is Monday through Friday
except for holidays.  The New York Stock Exchange is closed on the following
holidays:  New Year's Day, Martin Luther King, Jr. Day, Presidents' Day
(observed), Good Friday, Memorial Day (observed), Independence Day (observed),
Labor Day, Thanksgiving Day and Christmas Day (observed).

     In the event that the New York Stock Exchange or the national securities
exchange on which stock options are traded adopt different trading hours on
either a permanent or temporary basis, the Trustees will reconsider the time at
which net asset value is computed.  In addition, each 

                                      B-90
<PAGE>
 
Fund may compute its net asset value as of any time permitted pursuant to any
exemption, order or statement of the SEC or its staff.

     For the purpose of calculating the net asset value of the Funds,
investments are valued under valuation procedures established by the Trustees.
Portfolio securities, for which accurate market quotations are readily
available, other than money market instruments, are valued as follows: (a) via
electronic feeds to the custodian bank containing dealer-supplied bid quotations
or bid quotations from a recognized pricing service; (b) securities for which
the custodian bank is unable to obtain an external price or with respect to
which the Investment Adviser believes an external price does not reflect
accurate market values, will be valued by the Investment Adviser in good faith
based on valuation models that take into account spread and daily yield changes
on government securities (i.e., matrix pricing); (c) overnight repurchase
agreements will be valued at cost; (d) term repurchase agreements (i.e., those
whose maturity exceeds seven days) and swaps, caps, collars and floors will be
valued at the average of the bid quotations obtained daily from at least one
dealer; (e) debt securities with a remaining maturity of 60 days or less are
valued at amortized cost, which the Trustees have determined to approximate fair
value; (f) spot and forward foreign currency exchange contracts will be valued
using a pricing service such as Reuters (if quotations are unavailable from a
pricing service or, if the quotations by the Investment Adviser are believed to
be inaccurate, the contracts will be valued by calculating the mean between the
last bid and asked quotations supplied by at least one independent dealers in
such contracts); (g) exchange-traded options and futures contracts will be
valued by the custodian bank at the last sale price on the exchange where such
contracts and options are principally traded if accurate quotations are readily
available; and (h) over-the-counter options will be valued by a broker
identified by the portfolio manager/trader.

     All other securities, including those for which a pricing service supplies
no exchange quotation or a quotation that is believed by the portfolio
manager/trader to be inaccurate, will be valued at fair value as stated in the
valuation procedures which were approved by the Board of Trustees.

     The value of all assets and liabilities expressed in foreign currencies
will be converted into U.S. dollar values at current exchange rates of such
currencies against U.S. dollars last quoted by any major bank.  If such
quotations are not available, the rate of exchange will be determined in good
faith by or under procedures established by the Board of Trustees.

     Generally, trading in securities on European and Far Eastern securities
exchanges and on over-the-counter markets is substantially completed at various
times prior to the close of business on each Business Day in New York (i.e., a
day on which the New York Stock Exchange is open for trading).  In addition,
European or Far Eastern securities trading generally or in a particular country
or countries may not take place on all Business Days in New York.  Furthermore,
trading takes place in various foreign markets on days which are not Business
Days in New York and days on which the Funds' net asset values are not
calculated.  Such calculation does not take place contemporaneously with the
determination of the prices of the majority of the portfolio securities used in
such calculation.  The impact of events that occur after the publication of
market quotations used by a Fund to price its securities but before the close of
regular trading on the New York Stock Exchange will normally not be reflected in
a Fund's next determined net asset value unless the 

                                      B-91
<PAGE>
 
Trust, in its discretion, makes an adjustment in light of the nature and
materiality of the event, its effect on Fund operations and other relevant
factors.

     The proceeds received by each Fund and each other series of the Trust from
the issue or sale of its shares, and all net investment income, realized and
unrealized gain and proceeds thereof, subject only to the rights of creditors,
will be specifically allocated to such Fund and constitute the underlying assets
of that Fund or series.  The underlying assets of each Fund will be segregated
on the books of account, and will be charged with the liabilities in respect of
such Fund and with a share of the general liabilities of the Trust.  Expenses of
the Trust with respect to the Funds and the other series of the Trust are
generally allocated in proportion to the net asset values of the respective
Funds of series except where allocations of direct expenses can otherwise be
fairly made.

                                 TAXATION

     The following is a summary of the principal U.S. federal income, and
certain state and local, tax considerations regarding the purchase, ownership
and disposition of shares in the Funds. This summary does not address special
tax rules applicable to certain classes of investors, such as tax-exempt
entities, insurance companies and financial institutions.  Each prospective
shareholder is urged to consult his or her own tax adviser with respect to the
specific federal, state, local and foreign tax consequences of investing in the
Funds.  This summary is based on the laws in effect on the date of this
Additional Statement, which are subject to change.

General
- -------

     Each Fund is treated as a separate entity for tax purposes, has elected to
be treated as a regulated investment company and intends to qualify for such
treatment for each taxable year under Subchapter M of the Code.  To qualify as
such, a Fund must satisfy certain requirements relating to the sources of its
income, diversification of its assets and distribution of its income to
shareholders.  As a regulated investment company, a Fund will not be subject to
federal income or excise tax on any net investment income and net realized
capital gains that are distributed to its shareholders in accordance with
certain timing requirements of the Code.

     Qualification as a regulated investment company under the Code requires,
among other things, that (a) a Fund derive at least 90% of its gross income
(including tax-exempt interest) for its taxable year from dividends, interest,
payments with respect to securities loans and gains from the sale or other
disposition of stocks or securities, or foreign currencies or other income
(including but not limited to gains from options, futures and forward contracts)
derived with respect to its business of investing in such stock, securities or
currencies (the "90% gross income test"); and (b) a Fund diversify its holdings
so that, at the close of each quarter of its taxable year, (i) at least 50% of
the market value of its total (gross) assets is comprised of cash, cash items,
U.S. Government Securities, securities of other regulated  investment companies
and other securities limited in respect of any one issuer to an amount not
greater in value than 5% of the value of the Fund's total assets and to not more
than 10% of the  outstanding voting securities of such issuer, and (ii) not more
than 25% of the value of its total (gross) assets is invested in  the securities
of any one issuer (other than U.S. 

                                      B-92
<PAGE>
 
Government Securities and securities of other regulated investment companies) or
two or more issuers controlled by a Fund and engaged in the same, similar or
related trades or businesses.

     Future Treasury regulations could provide that qualifying income under the
90% gross income test will not include gains from foreign currency transactions
that are not directly related to Core Fixed Income, Global Income or High Yield
Fund's principal business of investing in stock or securities or options and
futures with respect to stock or securities.  Using foreign currency positions
or entering into foreign currency options, futures and forward contracts for
purposes other than hedging currency risk with respect to securities in Core
Fixed Income, Global Income or High Yield Fund's portfolio or anticipated to be
acquired may not qualify as "directly related" under these tests.

     As a regulated investment company, a Fund will not be subject to U.S.
federal income tax on the portion of its income and capital gains that it
distributes to its shareholders in any taxable year for which it distributes, in
compliance with the Code's timing and other requirements, at least 90% of its
"investment company taxable income" (which includes dividends, taxable interest,
taxable original issue discount income, market discount income, income from
securities lending, net short-term capital gain in excess of net long-term
capital loss, certain net realized foreign exchange gains, and any other taxable
income other than "net capital gain" as defined below and is reduced by
deductible expenses) and at least 90% of the excess of its gross tax-exempt
interest income, if any, over certain disallowed deductions ("net tax-exempt
interest").  A Fund may retain for investment its "net capital gain" (which
consists of the excess of its net long-term capital gain over its net short-term
capital loss).  However, if a Fund retains any investment company taxable income
or net capital gain, it will be subject to tax at regular corporate rates on the
amount retained.  If a Fund retains any net capital gain, that Fund may
designate the retained amount as undistributed net capital gain in a notice to
its shareholders who, if subject to U.S. federal income tax on long-term capital
gains, (i) will be required to include in income for federal income tax
purposes, as long-term capital gain, their shares of such undistributed amount;
and (ii) will be entitled to credit their proportionate shares of the tax paid
by that Fund against their U.S. federal income tax liabilities, if any, and to
claim refunds to the extent the credit exceeds such liabilities.  For  U.S.
federal income tax purposes, the tax basis of shares owned by a shareholder of
the Fund will be increased by an amount equal under current law to 65% of the
amount of undistributed net  capital gain included in the shareholder's gross
income.  Each Fund intends to distribute for each taxable year to its
shareholders all or substantially all of its investment company taxable income
(if any), net capital gain and any net tax-exempt interest.  Exchange control or
other foreign laws, regulations or practices may restrict repatriation of
investment income, capital or the proceeds of securities sales by foreign
investors such as Core Fixed Income or Global Income Fund and may therefore make
it more difficult for Core Fixed Income or Global Income Fund to satisfy the
distribution requirements described above, as well as the excise tax
distribution requirements described below.  However, Core Fixed Income Fund and
Global Income Fund generally expect to be able to obtain sufficient cash to
satisfy such requirements from new investors, the sale of securities or other
sources.  If for any taxable year a Fund does not qualify as a regulated
investment company, it will be taxed on all of its investment company taxable
income and net capital gain at corporate rates, its net tax-exempt interest (if
any) may be subject to the alternative minimum tax, and its distributions to
shareholders will be taxable as ordinary dividends to the extent of its current
and accumulated earnings and profits.

     For federal income tax purposes, each Fund is permitted to carry forward a
net capital loss in any year to offset its own capital gains, if any, during the
eight years following the year of the loss.  At October 31, 1998, the Funds had
approximately the following amounts of capital loss carry forwards:

</TABLE>

     These amounts are available to be carried forward to offset future capital
gains to the extent permitted by the Code and applicable tax regulations.

     In order to avoid a 4% federal excise tax, each Fund must distribute or be
deemed to have distributed by December 31 of each calendar year at least 98% of
its taxable ordinary income for such year, at least 98% of the excess of its
capital gains over its capital losses (generally computed on the basis of the
one-year period ending on October 31 of such year) and 100%  of any taxable
ordinary income and the excess of capital gains over capital losses for the
prior year that were not distributed during such year and on which the Fund did
not pay federal income tax.  The Funds anticipate that they will generally make
timely distributions of income and capital gains in compliance with these
requirements so that they will generally not be required to pay the excise tax.

     For federal income tax purposes, dividends declared by a Fund in October,
November or December as of a record date in such a month that are actually paid
in January of the following year will be treated as if they were received by
shareholders on December 31 of the year declared.

     The Tax Exempt Funds may purchase Municipal Securities together with the
right to resell the securities to the seller at an agreed-upon price or yield
within a specified period prior to the maturity date of  the securities.  Such a
right to resell is commonly known as a "put" and is also referred to as a
"standby commitment."  The Tax Exempt Funds may pay for a standby commitment
either separately, in cash, or in the form of a higher price for the securities
that are acquired subject to the standby commitment, thus increasing the cost of
securities and reducing the yield otherwise available.  Additionally, the Tax
Exempt Funds may purchase beneficial interests in Municipal Securities held by
trusts, custodial arrangements or partnerships and/or combined with third-party
puts and other types of features such as interest rate swaps; those investments
may require the Fund to pay "tender fees" or other fees for the various features
provided.

     The IRS has issued a revenue ruling to the effect that, under specified
circumstances, a registered investment company will be the owner of tax-exempt
municipal obligations acquired subject to a put option.  The IRS has also issued
private letter rulings to certain taxpayers (which do not serve as precedent for
other taxpayers) to the effect that tax-exempt interest received by a regulated
investment company with respect to such obligations will be tax-exempt in the
hands of 

                                      B-94
<PAGE>
 
the company and may be distributed to its shareholders as exempt-interest
dividends. The IRS has subsequently announced that it will not ordinarily issue
advance ruling letters as to the identity of the true owner of property in cases
involving the sale of securities or participation interests therein if the
purchaser has the right to cause the security, or the participation interest
therein, to be purchased by either the seller or a third party. Each of the Tax
Exempt Funds intends to take the position that it is the owner of any municipal
obligations acquired subject to a standby commitment or other third party put
and that tax-exempt interest earned with respect to such municipal obligations
will be tax-exempt in its hands. There is no assurance that the IRS will agree
with such position in any particular case. Additionally, the federal income tax
treatment of certain other aspects of these investments, including the treatment
of tender fees paid by these Funds, in relation to various regulated investment
company tax provisions is unclear. However, the Investment Adviser intends to
manage the Tax Exempt Funds' portfolios in a manner designed to minimize any
adverse impact from the tax rules applicable to these investments.

     Gains and losses on the sale, lapse, or other termination of options and
futures contracts, options thereon and certain forward contracts (except certain
foreign currency options, forward contracts and futures contracts) will
generally be treated as capital gain and losses.  Certain of the futures
contracts, forward contracts and options held by a Fund will be required to be
"marked-to-market" for federal income tax purposes, that is, treated as having
been sold at their fair market value on the last day of the Fund's taxable year.
These provisions may require a Fund to recognize income or gains without a
concurrent receipt of cash. Any gain or loss recognized on actual or deemed
sales of these futures contracts, forward contracts or options will (except for
certain foreign currency options, forward contracts, and futures contracts) be
treated as 60% long-term capital gain or loss and 40% short-term capital gain or
loss.  As a result of certain hedging transactions entered into by a Fund, that
Fund may be required to defer the recognition of losses on futures or forward
contracts and options or underlying securities or foreign currencies to the
extent of any unrecognized gains on related positions held by the Fund and the
characterization of gains or losses as long-term or short-term may be changed.
The tax provisions described above applicable to options, futures and forward
contracts may affect the amount, timing, and character of a Fund's distributions
to shareholders. Certain tax elections may be available to the Funds to mitigate
some of the unfavorable consequences described in this paragraph.

     Section 988 of the Code contains special tax rules applicable to certain
foreign currency transactions and instruments that may affect the amount, timing
and character of income, gain or loss recognized by Core Fixed Income Fund,
Global Income Fund and High Yield Fund.  Under these rules, foreign exchange
gain or loss realized by these Funds with respect to foreign currencies and
certain futures and options thereon, foreign currency-denominated debt
instruments, foreign currency forward contracts, and foreign currency-
denominated payables and receivables will generally be treated as ordinary
income or loss, although in some cases elections may be available that would
alter this treatment.  If a net foreign exchange loss treated as ordinary loss
under Section 988 of the Code were to exceed a Fund's investment company taxable
income (computed without regard to such loss) for a taxable year, the resulting
loss would not be deductible by the Fund or its shareholders in future years.
Net loss, if any, from certain foreign currency transactions or instruments
could exceed net investment income otherwise calculated for accounting purposes
with the result being either no dividends being paid or a portion of Core Fixed
Income Fund's, 

                                      B-95
<PAGE>
 
Global Income Fund's or High Yield Fund's dividends being treated as a return of
capital for tax purposes, nontaxable to the extent of a shareholder's tax basis
in his or her shares and, once such basis is exhausted, generally giving rise to
capital gains.

     Core Fixed Income, Global Income and High Yield Funds may be subject to
foreign taxes on income (possibly including, in some cases, capital gains) from
foreign securities.  Tax conventions between certain countries and the United
States may reduce or eliminate such taxes in some cases.  Because more than 50%
of Global Income Fund's total assets at the close of any taxable year will
generally consist of stock or securities of foreign corporations, Global Income
Fund will generally qualify to file an election with the IRS pursuant to which
shareholders of Global Income Fund would be required to (i) include in ordinary
gross income (in addition to taxable dividends actually received) their pro rata
shares of foreign income taxes paid by Global Income Fund that are treated as
income taxes under U.S. tax regulations (which excludes, for example, stamp
taxes, securities transaction taxes, and similar taxes) even though not actually
received by such shareholders; and (ii) treat such respective pro rata portions
as foreign income taxes paid by them.  Global Income Fund may or may not make
this election for any particular taxable year.  Core Fixed Income and High Yield
Funds will not satisfy the 50% requirement described above and, therefore, will
not make this election.  Core Fixed Income and High Yield Funds and, if it does
not make the election, Global Income Fund will, however, be entitled to deduct
such taxes in computing the amounts they are required to distribute.

     If Global Income Fund makes this election, its shareholders may then deduct
such pro rata portions of qualified foreign taxes in computing their taxable
incomes, or, alternatively, use them as foreign tax credits, subject to
applicable limitations, against their U.S. federal income taxes.  Shareholders
who do not itemize deductions for federal income tax purposes will not, however,
be able to deduct their pro rata portion of qualified foreign taxes paid by
Global Income Fund, although such shareholders will be required to include their
shares of such taxes in gross income if Global Income Fund makes the election
referred to above.

     If a shareholder chooses to take a credit for the foreign taxes deemed paid
by such shareholder as a result of any such election by Global Income Fund, the
amount of the credit that may be claimed in any year may not exceed the same
proportion of the U.S. tax against which such credit is taken which the
shareholder's taxable income from foreign sources (but not in excess of the
shareholder's entire taxable income) bears to his or her entire taxable income.
For this purpose, distributions from long-term and short-term capital gains or
foreign currency gains by Global Income Fund will generally not be treated as
income from foreign sources.  This foreign tax credit limitation may also be
applied separately to certain specific categories of foreign-source income and
the related foreign taxes.  As a result of these rules, which have different
effects depending upon each shareholder's particular tax situation, certain
shareholders of Global Income Fund may not be able to claim a credit for the
full amount of their proportionate shares of the foreign taxes paid by the Fund.

     Shareholders who are not liable for U.S. federal income taxes, including
tax-exempt shareholders, will ordinarily not benefit from this election.  Each
year, if any, that Global Income Fund files the election described above, its
shareholders will be notified of the amount of (i) each 

                                      B-96
<PAGE>
 
shareholder's pro rata share of qualified foreign income taxes paid by Global
Income Fund; and (ii) the portion of Fund dividends which represents income from
each foreign country.

     If Core Fixed Income, Global Income or High Yield Funds acquire stock
(including, under proposed regulations, an option to acquire stock such as is
inherent in a convertible bond) in certain foreign corporations ("passive
foreign investment companies") that receive at least 75% of their annual gross
income from passive sources (such as interest, dividends, rents, royalties or
capital gain) or hold at least 50% of their assets in investments producing such
passive income, the Fund could be subject to federal income tax and additional
interest charges on "excess distributions" received from such companies or gain
from the sale of such stock in such companies, even if all income or gain
actually received by the Fund is timely distributed to its shareholders.  The
Fund would not be able to pass through to its shareholders any credit or
deduction for such a tax.  Certain elections may, if available, ameliorate these
adverse tax consequences, but any such election would require the Fund to
recognize taxable income or gain without the concurrent receipt of cash. Core
Fixed Income, Global Income and High Yield Funds may limit and/or manage their
holdings in passive foreign investment companies to minimize their tax liability
or maximize their return from these investments.

     A Fund's investment in zero coupon securities, deferred interest
securities, capital appreciation bonds or other securities bearing original
issue discount or, if a Fund elects to include market discount in income
currently, market discount, as well as any "mark-to-market" gain from certain
options, futures or forward contracts, as described above, will generally cause
it to realize income or gain prior to the receipt of cash payments with respect
to these securities or contracts.  In order to obtain cash to enable it to
distribute this income or gain, maintain its qualification as a regulated
investment company and avoid federal income or excise taxes, a Fund may be
required to liquidate portfolio securities that it might otherwise have
continued to hold.

     Investment in lower-rated securities may present special tax issues for a
Fund to the extent actual or anticipated defaults may be more likely with
respect to such securities.  Tax rules are not entirely clear about issues such
as when a Fund may cease to accrue interest, original issue discount, or market
discount; when and to what extent deductions may be taken for bad debts or
worthless securities; how payment received on obligations in default should be
allocated between principal and income; and whether exchanges of debt
obligations in a workout context are taxable.  These and other issues will be
addressed by a Fund, in the event it invests in such securities, in order to
seek to eliminate or minimize any adverse tax consequences.

     The federal income tax rules applicable to mortgage dollar rolls and
interest rate and currency swaps, floors, caps and collars are unclear in
certain respects, and a Fund may also be required to account for these
instruments under tax rules in a manner that, under certain circumstances, may
limit its transactions in these instruments.

Taxable U.S. Shareholders - Distributions

     Tax Exempt Funds.  Each Tax Exempt Fund expects to qualify to pay "exempt-
interest dividends," as defined in the Code.  To qualify to pay exempt-interest
dividends, the applicable 

                                      B-97
<PAGE>
 
Fund must, at the close of each quarter of its taxable year, have at least 50%
of the value of its total assets invested in Municipal Securities whose interest
is excluded from gross income under Section 103(a) of the Code. In purchasing
Municipal Securities, each Tax Exempt Fund intends to rely on opinions of
nationally recognized bond counsel for each issue as to the excludability of
interest on such obligations from gross income for federal income tax purposes.
A Tax Exempt Fund will not undertake independent investigations concerning the
tax-exempt status of such obligations, nor does it guarantee or represent that
bond counsels' opinions are correct. Bond counsels' opinions will generally be
based in part upon covenants by the issuers and related parties regarding
continuing compliance with federal tax requirements. Tax laws not only limit the
purposes for which tax-exempt bonds may be issued and the supply of such bonds,
but also contain numerous and complex requirements that must be satisfied on a
continuing basis in order for bonds to be and remain tax-exempt. If the issuer
of a bond or a user of a bond-financed facility fails to comply with such
requirements at any time, interest on the bond could become taxable, retroactive
to the date the obligation was issued. In that event, a portion of a Tax Exempt
Fund's distributions attributable to interest the Fund received on such bond for
the current year and for prior years could be characterized or recharacterized
as taxable income. The availability of tax-exempt obligations and the value of a
Tax Exempt Fund's portfolio may be affected by restrictive federal income tax
legislation enacted in recent years or by similar, future legislation. If a Tax
Exempt Fund satisfies the applicable requirements, dividends paid by the Fund
which are attributable to tax exempt interest on Municipal Securities and
designated by the Fund as exempt-interest dividends in a written notice mailed
to its shareholders within 60 days after the close of its taxable year may be
treated by shareholders as items of interest excludable from their gross income
under Section 103(a) of the Code. Exempt-interest dividends a Tax Exempt Fund
receives from other regulated investment companies, including exempt-interest
dividends on auction rate preferred securities of such companies held by a Fund,
are treated as interest on Municipal Securities and may be distributed by a Tax
Exempt Fund as exempt-interest dividends. The recipient of tax-exempt income is
required to report such income on his or her federal income tax return. The Code
provides that interest on indebtedness incurred or continued to purchase or
carry shares of a Tax Exempt Fund is not deductible to the extent attributable
to exempt-interest dividends.

     Although all or a substantial portion of the dividends paid by a Tax Exempt
Fund may be excluded by shareholders of such Fund from their gross income for
federal income tax purposes, each Tax Exempt Fund may purchase specified private
activity bonds, the interest from which (including a Fund's distributions
attributable to such interest) may be a preference item for purposes of the
federal alternative minimum tax (both individual and corporate). All exempt-
interest dividends from a Tax Exempt Fund, whether or not attributable to
private activity bond interest, may increase a corporate shareholder's
liability, if any, for corporate alternative minimum tax, and will be taken into
account in determining the extent to which a shareholder's Social Security or
certain railroad retirement benefits are taxable.

     The Tax Exempt Funds are not intended to constitute a balanced investment
program and are not designed for investors seeking capital appreciation or
maximum tax-exempt income irrespective of fluctuations in principal.  Shares of
the Tax Exempt Funds would not be suitable for tax-exempt institutions and may
not be suitable for retirement plans qualified under Section 401 of the Code,
H.R. 10 plans and individual retirement accounts since such plans and accounts
are 

                                      B-98
<PAGE>
 
generally tax-exempt and, therefore, would not gain any additional benefit from
the Funds' dividends being tax-exempt. In addition, the Tax Exempt Funds may not
be an appropriate investment for persons or entities that are "substantial
users" of facilities financed by private activity bonds or "related persons"
thereof. "Substantial user" is defined under U.S. Treasury Regulations to
include a non-exempt person which regularly uses a part of such facilities in
its trade or business and whose gross revenues derived with respect to the
facilities financed by the issuance of bonds are more than 5% of the total
revenues derived by all users of such facilities, which occupies more than 5% of
the usable area of such facilities or for which such facilities or a part
thereof were specifically constructed, reconstructed or acquired. "Related
persons" include certain related natural persons, affiliated corporations,
partnerships and its partners and an S corporation and its shareholders. A
shareholder is advised to consult his or her tax adviser with respect to whether
exempt-interest dividends retain the exclusion under Section 103(a) if such
shareholder would be treated as a "substantial user" under Section 147(a)(1)
with respect to some or all of the tax-exempt obligations held by a Tax Exempt
Fund.

     All Funds.  Distributions from investment company taxable income, as
defined above, are taxable to shareholders who are subject to tax as ordinary
income whether paid in cash or reinvested in additional shares.  Taxable
distributions include distributions from any Fund, including the Short Duration
Tax-Free Fund and the Municipal Income Fund, that are attributable to (i)
taxable income, including but not limited to dividends, taxable bond interest,
recognized market discount income, original issue discount income accrued with
respect to taxable bonds, income from repurchase agreements, income from
securities lending, income from dollar rolls, income from interest rate or
currency swaps, caps, floors and collars, and a portion of the discount from
certain stripped tax-exempt obligations or their coupons; or (ii) capital gains
from the sale of securities or other investments (including from the disposition
of rights to when-issued securities prior to issuance) or from options, futures
or certain forward contracts. Any portion of such taxable distributions that is
attributable to a Fund's net capital gain, as defined above, may be designated
by the Fund as a "capital gain dividend," taxable to shareholders as long-term
capital gain whether received in cash or additional shares and regardless of the
length of time their shares of a Fund have been held.

     It is expected that distributions made by the Funds will ordinarily not
qualify for the dividends-received deduction for corporations because qualifying
distributions may be made only from a Fund's dividend income that it receives
from stock in U.S. domestic corporations.  The Funds do not intend to purchase
stock of domestic corporations other than in limited instances, including
investments in investment companies, distributions from which may in rare cases
qualify as dividends for this purpose. The dividends-received deduction, if
available, is reduced to the extent the shares with respect to which the
dividends are received are treated as debt-financed under the federal income tax
law and is eliminated if the shares are deemed to have been held for less than a
minimum period, generally 46 days.  Receipt of certain distributions qualifying
for the deduction may result in reduction of the tax basis of the corporate
shareholder's shares and may give rise to or increase its liability for federal
corporate alternative minimum tax.

     Distributions in excess of a Fund's current and accumulated earnings and
profits, as computed for federal income tax purposes, will first reduce a
shareholder's basis in his or her shares and, after the shareholder's basis is
reduced to zero, will generally constitute capital gains to a shareholder who
holds his or her shares as capital assets.  Amounts that are not allowable as a

                                      B-99
<PAGE>
 
deduction in computing taxable income, including expenses associated with
earning tax-exempt interest income, do not reduce a Fund's current earnings and
profits for these purposes.  Consequently, the portion, if any, of Short
Duration Tax-Free Fund's or Municipal Income Fund's distributions from gross
tax-exempt interest income that exceeds its net tax-exempt interest would be
taxable as ordinary income to the extent of such disallowed deductions even
though such excess portion may represent an economic return of capital.

     Shareholders receiving a distribution in the form of newly issued shares
will be treated for U.S. federal income tax purposes as receiving a distribution
in an amount equal to the amount of cash that they would have received had they
elected to receive cash and will have a cost basis in the shares received equal
to such amount.

     After the close of each calendar year, each Fund will inform shareholders
of the federal income tax status of its dividends and distributions for such
year, including the portion of such dividends, if any, that qualifies as tax-
exempt or as capital gain, the portion, if any, that should be treated as a tax
preference item for purposes of the federal alternative minimum tax and the
foreign tax credits, if any, associated with such dividends. Shareholders who
have not held shares of Short Duration Tax-Free Fund or Municipal Income Fund
for such Fund's full taxable year may have designated as tax-exempt or as a tax
preference item a percentage of distributions which is not equal to the actual
amount of tax-exempt income or tax preference item income earned by Short
Duration Tax-Free Fund or Municipal Income Fund during the period of their
investment in Short Duration Tax-Free Fund or Municipal Income Fund, as the case
may be.

     All distributions, whether received in shares or in cash, as well as
redemptions and exchanges, must be reported by each shareholder who is required
to file a U.S. federal income tax return.

     Different tax treatment, including penalties on certain excess
contributions and deferrals, certain pre-retirement and post-retirement
distributions, and certain prohibited transactions is accorded to accounts
maintained as qualified retirement plans. Shareholders should consult their tax
advisers for more information.

Taxable U.S. Shareholders--Sale of Shares

     When a shareholder's shares are sold, redeemed or otherwise disposed of in
a transaction that is treated as a sale for tax purposes, the shareholder will
generally recognize gain or loss equal to the difference between the
shareholder's adjusted tax basis in the shares and the cash, or fair market
value of any property, received. Assuming the shareholder holds the shares as a
capital asset at the time of such sale, such gain or loss should be capital in
character, and long-term if the shareholder has a tax holding period for the
shares of more than one year, otherwise short-term, subject to the rules
described below. Shareholders should consult their own tax advisers with
reference to their particular circumstances to determine whether a redemption
(including an exchange) or other disposition of Fund shares is properly treated
as a sale for tax purposes, as is assumed in this discussion.  All or a portion
of a sales charge paid in purchasing Class A shares of a Fund cannot be taken
into account for purposes of determining gain or loss on the redemption or

                                     B-100
<PAGE>
 
exchange of such shares within 90 days after their purchase to the extent shares
of that Fund or another fund are subsequently acquired without payment of a
sales charge pursuant to the reinvestment or exchange privilege.  Any
disregarded portion of such charge will result in an increase in the
shareholder's tax basis in the shares subsequently acquired. If a shareholder
received a capital gain dividend with respect to shares and such shares have a
tax holding period of six months or less at the time of the sale or redemption,
then any loss the shareholder realizes on the sale or redemption will be treated
as a long-term capital loss to the extent of such capital gain dividend.  Also,
any losses realized by shareholders who dispose of shares of Short Duration Tax-
Free or Municipal Income Funds with a tax holding period of six months or less
are disallowed to the extent of any exempt-interest dividends received with
respect to such shares. Additionally, any loss realized on a sale or redemption
of shares of a Fund may be disallowed under "wash sale" rules to the extent the
shares disposed of are replaced with other shares of the same Fund within a
period of 61 days beginning 30 days before and ending 30 days after the shares
are disposed of, such as pursuant to a dividend reinvestment in shares of the
Fund. If disallowed, the loss will be reflected in an adjustment to the basis of
the shares acquired.

Backup Withholding

     Each Fund will be required to report to the IRS all taxable distributions,
as well as gross proceeds from the redemption or exchange of Fund shares, except
in the case of certain exempt recipients, i.e., corporations and certain other
investors distributions to which are exempt from the information reporting
provisions of the Code.  Under the backup withholding provisions of Code Section
3406 and applicable Treasury regulations, all such reportable distributions and
proceeds may be subject to backup withholding of federal income tax at the rate
of 31% in the case of non-exempt shareholders who fail to furnish the Funds with
their correct taxpayer identification number ("TIN") and with certain required
certifications or if the IRS or a broker notifies the Funds that the number
furnished by the shareholder is incorrect or that the shareholder is subject to
backup withholding as a result of failure to report interest or dividend income.
However, any taxable distributions from Short Duration Tax-Free Fund or
Municipal Income Fund will not be subject to backup withholding if the
applicable Fund reasonably estimates that at least 95% of its distributions will
be exempt-interest dividends. A Fund may refuse to accept an application that
does not contain any required taxpayer identification number or certification
that the number provided is correct.  If the backup withholding provisions are
applicable, any such distributions and proceeds, whether taken in cash or
reinvested in shares, will be reduced by the amounts required to be withheld.
Any amounts withheld may be credited against a shareholder's U.S. federal income
tax liability.  If you do not have a TIN, you should apply for one immediately
by contacting your local office of the Social Security Administration or the
Internal revenue (IRS).  Backup withholding could apply to payments relating to
your account while you are waiting receipt of a TIN.    Special rules apply for
certain entities.  For example, for an account established under a Uniform Gifts
or Transfers to Minors Act, the TIN of the minor should be furnished.  Investors
should consult their tax advisers about the applicability of the backup
withholding provisions.

Non-U.S. Shareholders

     The foregoing discussion relates solely to U.S. federal income tax law as
it applies to "U.S. persons" (i.e., U.S. citizens and residents and U.S.
domestic corporations, partnerships, trusts and estates) subject to tax under
such law. Dividends from investment company taxable income distributed by a Fund
to a shareholder who is not a U.S. person will be subject to U.S. withholding
tax at the rate of 30% (or a lower rate provided by an applicable tax treaty)
unless the dividends are effectively connected with a U.S. trade or business of
the shareholder, in which case the dividends will be subject to tax on a net
income basis at the graduated rates applicable to U.S. individuals or domestic
corporations. Distributions of net capital gain, including amounts retained by a
Fund which are designated as undistributed capital gains, to a shareholder who
is not a U.S. person will not be subject to U.S. federal income or withholding
tax unless the distributions are effectively connected with the shareholder's
trade or business in the United States or, in the case of a shareholder who is a
nonresident alien individual, the shareholder is present in the United States
for 183 days or more during the taxable year and certain other conditions are
met. Non-U.S. shareholders may also be subject to U.S. withholding tax on deemed
income resulting from any election by Global Income Fund to treat qualified
foreign taxes it pays as passed through to shareholders (as described above),
but they may not be able to claim a U.S. tax credit or deduction with respect to
such taxes.

     Any capital gain realized by a shareholder who is not a U.S. person upon a
sale or redemption of shares of a Fund will not be subject to U.S. federal
income or withholding tax unless the gain is effectively connected with the
shareholder's trade or business in the United States, or in the case of a
shareholder who is a nonresident alien individual, the shareholder is present in
the United States for 183 days or more during the taxable year and certain other
conditions are met.

     Non-U.S. persons who fail to furnish a Fund with an IRS Form W-8 or
acceptable substitute may be subject to backup withholding at the rate of 31% on
capital gain dividends and the proceeds of redemptions and exchanges.  Each
shareholder who is not a U.S. person should consult his or her tax adviser
regarding the U.S. and non-U.S. tax consequences of ownership of shares of and
receipt of distributions from a Fund.

State and Local Taxes

     A Fund may be subject to state or local taxes in certain jurisdictions in
which the Fund may be deemed to be doing business.  A state income (and possibly
local income and/or intangible property) tax exemption is generally available to
the extent (if any) a Fund's distributions are derived from interest on (or, in
the case of intangible property taxes, the value of its assets is attributable
to) certain U.S. Government obligations and/or tax-exempt municipal obligations
issued by or on behalf of the particular state or a political subdivision
thereof, provided in some states that certain thresholds for holdings of such
obligations and/or reporting requirements are satisfied.  In addition, in those
states or localities which have income tax laws, the treatment of a Fund and its
shareholders under such laws may differ from their treatment under federal
income tax laws, and investment in a Fund may have tax consequences for
shareholders different from those of a direct 

                                     B-102
<PAGE>
 
investment in such Fund's portfolio securities. Shareholders should consult
their own tax advisers concerning these matters.

                            PERFORMANCE INFORMATION

     Each Fund may from time to time quote or otherwise use yield and total
return information in advertisements, shareholder reports or sales literature.
Thirty-day yield and average annual total return values are computed pursuant to
formulas specified by the SEC.  Each Fund may also from time to time quote
distribution rates in reports to shareholders and in sales literature.

     Thirty-day yield is derived by dividing net investment income per share
earned during the period by the maximum public offering price per share on the
last day of such period.  Yield is then annualized by assuming that yield is
realized each month for 12 months and is reinvested every six months.  Net
investment income per share is equal to the dividends and interest earned during
the period, reduced by accrued expenses for the period. The calculation of net
investment income for these purposes may differ from the net investment income
determined for accounting purposes.

     Tax equivalent yield represents the yield an investor would have to earn to
equal, after taxes, a Tax Exempt Fund's tax-free yield. Tax equivalent yield is
calculated by dividing a Tax Exempt Fund's tax-exempt yield by one minus a
stated federal and/or state tax rate.

     Distribution rate for a specified period is calculated by annualizing
distributions of net investment income for such period and dividing this amount
by the net asset value per share on the last day of the period.

     Average annual total return for a specified period is derived by
calculating the actual dollar amount of the investment return on a $1,000
investment made at the maximum public offering price applicable to the relevant
class (i.e., net asset value in the case of each class other than Class A) at
the beginning of the period, and then calculating the annual compounded rate of
return which would produce that amount, assuming a redemption (and payment of
any contingent deferred sales charge) at the end of the period.  This
calculation assumes a complete redemption of the investment.  It also assumes
that all dividends and distributions are reinvested at net asset value on the
reinvestment dates during the period.

     Year-by-year total return and cumulative total return for a specified
period are each derived by calculating the percentage rate required to make a
$1,000 investment (made at the maximum public offering price per share with all
distributions reinvested) at the beginning of such period equal to the actual
total value of such investment at the end of such period.

     Total return calculations for Class A Shares reflect the effect of paying
the maximum initial sales charge.  Investment at a lower sales charge would
result in higher performance figures.  Total return calculations for Class B and
Class C Shares reflect deduction of the applicable CDSC imposed upon redemption
of Class B and Class C Shares held for the applicable period.  Each Fund may
also from time to time advertise total return on a cumulative, average, year-by-
year or other basis for various specified periods by means of quotations,
charts, graphs or schedules.  In addition, 

                                     B-103

each Fund may furnish total return calculations based on investments at various
sales charge levels or at NAV. Any performance information which is based on a
Fund's NAV per Share would be reduced if any applicable sales charge were taken
into account. In addition to the above, each Fund may from time to time
advertise its performance relative to certain averages, performance rankings,
indices, other information prepared by recognized mutual fund statistical
services and investments for which reliable performance information is
available. The Fund's performance quotations do not reflect any fees charged by
an Authorized Dealer, Service Organization or other financial intermediary to
its customer accounts in connection with investments in the Funds.

     The following table presents 30-day yield, tax equivalent yield (Short
Duration Tax-Free and Municipal Income Funds only), distribution rate and
average annual total return (capital plus reinvestment of all distributions) for
each class of shares outstanding for the periods indicated.

     Thirty-day yield, tax equivalent yield (Short Duration Tax- Free and
Municipal Income Funds only), distribution rate and average annual total return
are calculated separately for each class of shares in existence of each Fund.
Each class of shares of each Fund is subject to different fees and expenses and
may have different returns for the same period.  Any performance data for Class
A, Class B or Class C Shares which is based upon a Fund's net asset value per
share would be reduced if a sales charge were taken into account.

     The average annual total return calculation reflects a maximum initial
sales charge of 1.5% for Class A Shares of Adjustable Rate Government Fund; 2.0%
for Class A Shares of Short Duration Government and Short Duration Tax-Free
Funds; and 4.5% for Class A Shares of Government Income, Municipal Income, Core
Fixed Income, Global Income and High Yield Funds; the assumed deferred sales
charge for Class B Shares (2% maximum declining to 0% after three years for the
Short Duration Government and Short Duration Tax-Free Funds and 5% maximum
declining to 0% after six years for the Government Income, Municipal Income,
Core Fixed Income, Global Income and High Yield Funds); and the assumed deferred
sales charge for Class C Shares (1% if redeemed within 12 months of purchase).

     The Service Shares of Global Income Fund commenced operations on March 12,
1997; the Service Shares of Government Income and Municipal Income Funds
commenced operations on August 15, 1997. The Service Shares of these Funds had
no operating or performance history prior thereto.  However, in accordance with
interpretive positions expressed by the staff of the SEC, each of these Funds
has adopted the performance records of its respective Class A Shares from that
Class's inception date (August 2, 1991, February 10, 1993 and July 20, 1993,
respectively) to the inception dates of the Service Shares stated above.
Quotations of performance data of these Funds relating to this period include
the performance record of the applicable Class A Shares (excluding the impact of
any applicable front-end sales charge).  The performance records of the
applicable Class A Shares reflect the expenses actually incurred by the Fund.
These expenses include any asset-based sales charges (i.e., fees under
distribution and service plans) imposed and other operating expenses.  Total
return quotations are calculated pursuant to SEC-approved methodology.

The above table should not be considered a representation of future performance.

     Occasionally, statistics may be used to specify a Fund's volatility or
risk.  Measures of volatility or risk are generally used to compare a Fund's net
asset value or performance relative to a market index.  One measure of
volatility is beta.  Beta is the volatility of a fund relative to the total
market.  A beta of more than 1.00 indicates volatility greater than the market,
and a beta of less than 1.00 indicates volatility less than the market. Another
measure of volatility or risk is standard deviation. Standard deviation is used
to measure variability of net asset value or total return around 

                                     B-118
<PAGE>
 
an average, over a specified period of time. The premise is that greater
volatility connotes greater risk undertaken in achieving performance.

     Each Fund may from time to time advertise comparative performance as
measured by various independent sources, including, but not limited to, Lipper
                                                                        ------

 .    The performance of various types of securities (taxable money market funds,
     U.S. Treasury securities, adjustable rate mortgage securities, government
     securities, municipal bonds) over time.  However, the characteristics of
     these securities are not identical to, and may be very different from,
     those of a Fund's portfolio;

 .    Volatility of total return of various market indices (i.e., Lehman
     Government Bond Index, Standard and Poor's 500, IBC/Donoghue's Money Fund
     Average/All Taxable Index) over varying periods of time;

 .    Credit ratings of domestic government bonds in various countries;

     Performance data is based on historical results and is not intended to
indicate future performance.  Total return, 30-day yield, tax equivalent yield
and distribution rate will vary based on changes in market conditions, portfolio
expenses, portfolio investments and other factors.  The value of a Fund's shares

original cost upon redemption.  The Trust may also, at its discretion, from time
to time make a list of a Fund's holdings available to investors upon request.

                               OTHER INFORMATION
                                        
     As stated in the Prospectuses, the Trust may authorize Service
Organizations and other institutions that provide recordkeeping, reporting and
processing services to their customers to accept on the Trust's behalf purchase,
redemption and exchange orders placed by or on behalf of their customers and, if
approved by the Trust, to designate other intermediaries to accept such orders.
These institutions may receive payments from the Trust or Goldman Sachs for
their services.  Certain Service Organizations or institutions may enter into
sub-transfer agency agreements with the Trust or Goldman Sachs with respect to
their services.

     The Investment Adviser, Distributor and/or their affiliates may pay, out of
their own assets, compensation to Authorized Dealers, Service Organizations and
other financial intermediaries ("Intermediaries") in connection with the sale
and distribution of shares of the Funds and/or servicing of these shares. These
payments ("Additional Payments") would be in addition to the payments by the
Funds described in the Funds' Prospectuses and this Additional Statement for
distribution and shareholder servicing and processing, and would also be in
addition to the sales commissions payable to Intermediaries as set forth in the
Prospectus.  These Additional Payments may take the form of "due diligence"
payments for an Intermediary's examination of the Funds and payments for
providing extra employee training and information relating to the Funds;
"listing" fees for the placement of the Funds on a dealer's list of mutual funds
available for purchase by its customers; "finders" or "referral" fees for
directing investors to the Funds; "marketing support" fees for providing
assistance in promoting the sale of the Funds' shares; and payments for the sale
of shares and/or the maintenance of share balances.  In addition, the Investment
Adviser, Distributor and/or their affiliates may make Additional Payments for
subaccounting, administrative and/or shareholder processing services that are in
addition to any shareholder servicing and processing fees paid by the Funds.
The Additional Payments made by the Investment Adviser, Distributor and their
affiliates may be a fixed dollar amount, may be based on the number of customer
accounts maintained by an Intermediary, or may be based on a percentage of the
value of shares sold to, or held by, customers of the Intermediary involved, and
may be different for different Intermediaries.  Furthermore, the Investment
Adviser, Distributor and/or their affiliates may contribute to various non-cash
and cash incentive arrangements to promote the sale of shares, as well as
sponsor various educational programs, sales contests and/or promotions.  The
Investment Adviser, Distributor and their affiliates may also pay for the travel
expenses, meals, lodging and entertainment of Intermediaries and their
salespersons and guests in connection with educational, sales and promotional
programs, subject to applicable NASD regulations.  The Distributor currently
expects that such additional bonuses or incentives will not exceed 0.50% of the
amount of any sales.

     A Fund will redeem shares solely in cash up to the lesser of $250,000 or 1%
of the net asset value of the Fund during any 90-day period for any one
shareholder.  Each Fund, however, reserves the right to pay redemptions
exceeding $250,000 or 1% of the net asset value of each respective Fund at the
time of redemption by a distribution in kind of securities (instead of cash)
from such Fund.  The securities distributed in kind would be readily marketable
and would be valued for this 

                                     B-122
<PAGE>
 
purpose using the same method employed in calculating each Fund's net asset
value per share. See "Net Asset Value." If a shareholder receives redemption
proceeds in kind, the shareholder may incur transaction costs upon the
disposition of the securities received in the redemption.

     The right of a shareholder to redeem shares and the date of payment by each
Fund may be suspended for more than seven days for any period during which the
New York Stock Exchange is closed, other than the customary weekends or
holidays, or when trading on such Exchange is restricted as determined by the
SEC; or during any emergency, as determined by the SEC, as a result of which it
is not reasonably practicable for such Fund to dispose of securities owned by it
or fairly to determine the value of its net assets; or for such other period as
the SEC may by order permit for the protection of shareholders of such Fund.
(The Trust may also suspend or postpone the recommendation of the transfer of
shares upon the occurrence of any of the foregoing conditions).

     The Prospectuses and this Additional Statement do not contain all the
information included in the Registration Statement filed with the SEC under the
1933 Act with respect to the securities offered by the Prospectuses.  Certain

Other Purchase Information
- --------------------------

     The sales load waivers on the Funds' shares are due to the nature of the
investors involved and/or the reduced sales effort that is needed to obtain such
investments.

     If shares of a Fund are held in a "street name" account with an Authorized
Dealer, all recordkeeping, transaction processing and payments of distributions
relating to the beneficial owner's account will be performed by the Authorized
Dealer, and not by the Fund and its Transfer Agent.  Since the Funds will have
no record of the beneficial owner's transactions, a beneficial owner should
contact the Authorized Dealer to purchase, redeem or exchange shares, to make
changes in or give instructions concerning the account or to obtain information
about the account.  The transfer of shares in a "street name" account to an
account with another dealer or to an account directly with the Fund involves
special procedures and will require the beneficial owner to obtain historical
purchase information about the shares in the account from the Authorized Dealer.

Right of Accumulation - (Class A)
- ---------------------------------

     A Class A shareholder qualifies for cumulative quantity discounts if the
current purchase price of the new investment plus the shareholder's current
holdings of existing Class A Shares (acquired by purchase or exchange) of the
Funds and Class A Shares of any other Goldman Sachs Fund total the requisite
amount for receiving a discount.  For example, if a shareholder owns shares with
a current market value of $65,000 and purchases additional Class A Shares of the
Government Income Fund with a purchase price of $45,000, the sales charge for
the $45,000 purchase would be 3.0% (the rate applicable to a single purchase of
more than $100,000).  Class A Shares purchased without the imposition of a sales
charge and shares of another class of the Funds may not be aggregated with Class
A Shares purchased subject to a sales charge.  Class A Shares of the Funds and
any other Goldman Sachs Fund purchased (i) by an individual, his spouse and his
children; and (ii) by a trustee, guardian or other fiduciary of a single trust
estate or a single fiduciary account, will be combined for the purpose of
determining whether a purchase will qualify for such right of accumulation and,
if qualifying, the  applicable sales charge level.  For purposes of applying the
right of accumulation, shares of the Funds and any other Goldman Sachs Fund
purchased by an existing client of the Private Client Services Division of
Goldman Sachs will be combined with Class A Shares held by any other Private
Client Services account.  In addition, Class A Shares of the Funds and Class A
Shares of any other Goldman Sachs Fund purchased by partners, directors,
officers or employees of the same business organization or by groups of
individuals represented by and investing on the recommendation of the same
accounting firm, certain affinity groups or other similar organizations
(collectively, "eligible persons") may be combined for the purpose of
determining whether a purchase will qualify for the right of accumulation and,
if qualifying, the applicable sales charge level.  This right of accumulation is
subject to the following conditions:  (i) the business organization's, group's
or firm's agreement to cooperate in the offering of the Funds' shares to
eligible persons; and (ii) notification to the Funds at the time of purchase
that the investor is eligible for this right of accumulation.  In addition, in
connection with SIMPLE IRA accounts, cumulative quantity discounts are available
on a per plan basis if (1) your employee has been assigned a cumulative discount
number by Goldman Sachs; and (2) your account, alone or in 

                                     B-124
<PAGE>
 
combination with the accounts of other plan participants also invested in Class
A shares of the Goldman Sachs Funds totals the requisite aggregate amount as
described in the Prospectuses.

Statement of Intention - (Class A)
- ----------------------------------

     If a shareholder anticipates purchasing at least $100,000 ($500,000 in the
case of Adjustable Rate Government Fund and $250,000 in the case of Short
Duration Government and Short Duration Tax-Free Funds) of Class A Shares of a
Fund alone or in combination with Class A Shares of any other Goldman Sachs Fund
within a 13-month period, the shareholder may purchase shares of the Fund at a
reduced sales charge by submitting a Statement of Intention (the "Statement").
Shares purchased pursuant to a Statement will be eligible for the same sales
charge discount that would have been available if all of the purchases had been
made at the same time.  The shareholder or his Authorized Dealer must inform
Goldman Sachs that the Statement is in effect each time shares are purchased.
There is no obligation to purchase the full amount of shares indicated in the
Statement. A shareholder may include the value of all Class A Shares on which a
sales charge has previously been paid as an "accumulation credit" toward the
completion of the Statement, but a price readjustment will be made only on Class
A Shares purchased within 90 days before submitting the Statement.  The
Statement authorizes the Transfer Agent to hold in escrow a sufficient number of
shares which can be redeemed to make up any difference in the sales charge on
the amount actually invested.  For purposes of satisfying the amount specified
on the Statement, the gross amount of each investment, exclusive of any
appreciation on shares previously purchased, will be taken into account.

Cross-Reinvestment of Dividends and Distributions
- -------------------------------------------------

     Shareholders may receive dividends and distributions in additional shares
of the same class of the Fund in which they have invested or they may elect to
receive them in cash or shares of the same class of other mutual funds sponsored
by Goldman Sachs (the "Goldman Sachs Funds") or ILA Service Units of the Prime
Obligations Portfolio or the Tax-Exempt Diversified Portfolio, if they hold
Class A Shares of a Fund, or ILA Class B or Class C Units of the Prime
Obligations Portfolio, if they hold Class B or Class C Shares of a Fund (the
"ILA Portfolios").  A Portfolio shareholder should obtain and read the
prospectus relating to any other Goldman Sachs Fund or ILA Fund and its shares
or units and consider its investment objective, policies and applicable fees
before electing cross-reinvestment into that Fund. The election to cross-
reinvest dividends and capital gain distributions will not affect the tax
treatment of such dividends and distributions, which will be treated as received
by the shareholder and then used to purchase shares of the acquired  fund. Such
reinvestment of dividends and distributions in shares of other Goldman Sachs
Funds or ILA Portfolios is available only in states where such reinvestment may
legally be made.

Automatic Exchange Program
- --------------------------

     A shareholder may elect to exchange automatically a specified dollar amount
of shares of a Fund into an identical account of another Fund or an account
registered in a different name or with a different address, social security or
other taxpayer identification number, provided that the account in the acquired
fund has been established, appropriate signatures have been obtained and the
minimum initial investment requirement has been satisfied.  A Fund shareholder
should obtain and 

                                     B-125
<PAGE>
 
read the prospectus relating to any other Goldman Sachs Fund and its shares and
consider its investment objective, policies and applicable fees and expenses
before electing an automatic exchange into that Goldman Sachs Fund.

Systematic Withdrawal Plan
- --------------------------

     A systematic withdrawal plan (the "Systematic Withdrawal Plan") is
available to shareholders of a Fund whose shares are worth at least $5,000.  The
Systematic Withdrawal Plan provides for monthly payments to the participating
shareholder of any amount not less than $50.

     Dividends and capital gain distributions on shares held under the
Systematic Withdrawal Plan are reinvested in additional full and fractional
shares of the applicable Fund at net asset value. The Transfer Agent acts as
agent for the shareholder in redeeming sufficient full and fractional shares to
provide the amount of the systematic withdrawal payment.  The Systematic
Withdrawal Plan may be terminated at any time.  Goldman Sachs reserves the right
to initiate a fee of up to $5 per withdrawal, upon 30 days written notice to the
shareholder.  Withdrawal payments should not be considered to be dividends,
yield or income.  If periodic withdrawals continuously exceed new purchases and
reinvested dividends and capital gains distributions, the shareholder's original
investment will be correspondingly reduced and ultimately exhausted.  The
maintenance of a withdrawal plan concurrently with purchases of additional Class
A, Class B or Class C Shares would be disadvantageous because of the sales
charge imposed on purchases of Class A Shares or the imposition of a contingent
deferred sales charge ("CDSC") on redemptions of Class A, Class B and Class C
Shares.  The CDSC applicable to Class B and Class C Shares redeemed under a
systematic withdrawal plan may be waived.  See "Shareholder Guide" in the
Prospectus.  In addition, each withdrawal constitutes a redemption of shares,
and any gain or loss realized must be reported for federal and state income tax
purposes.  A shareholder should consult his or her own tax adviser with regard
to the tax consequences of participating in the Systematic Withdrawal Plan. For
further information or to request a Systematic Withdrawal Plan, please write or
call the Transfer Agent.

Offering Price of Class A Shares
- --------------------------------

     Class A Shares of Government Income, Municipal Income, Core Fixed Income,
Global Income and High Yield Funds are sold at a maximum sales charge of 4.5%,
Adjustable Rate Government Fund at 1.5% and Short Duration Government and Short
Duration Tax-Free Funds at 2%. Using the offering price as of October 31, 1998,
the maximum offering price of the Class A shares of each Fund's Shares then in
existence would be as follows:

                         DISTRIBUTION AND SERVICE PLANS
            (Class A Shares, Class B Shares and Class C Shares Only)
                                        
     Distribution and Service Plans. As described in the Prospectus, the Trust
     ------------------------------
has adopted, on behalf of Class A, Class B and Class C Shares of each Fund,
distribution and service plans (each a "Plan") pursuant to Rule 12b-1 under
the Act.

     The Plans for each Fund were most recently approved on July 22, 1998 by a
majority vote of the Trustees of the Trust, including a majority of the non-
interested Trustees of the Trust who have no direct or indirect financial
interest in the Plans, cast in person at a meeting called for the purpose of
approving the Plans.

     The compensation for distribution services payable under a Plan may not
exceed 0.25%, 0.75% and 0.75% per annum of a Fund's average daily net assets
attributable to Class A, Class B and Class C Shares, respectively, of such Fund.
Currently, Goldman Sachs has voluntarily agreed to limit such fees to 0.60% of
the average daily net assets attributable to Class B Shares of the Short
Duration Government and Short Duration Tax-Free Funds. Goldman Sachs may modify
or discontinue such limitation in the future at its discretion.

     Under the Plans for Class A (Global Income Fund only), Class B and Class C
Shares, Goldman Sachs is also entitled to received a separate fee for personal
and account maintenance services equal to an annual basis of 0.25% of each
Fund's average daily net assets attributable to Class B or Class C Shares.  With
respect to Class A Shares, the Distributor at its discretion may use
compensation for distribution services paid under the Plan for personal and
account maintenance services and expenses so long as such total compensation
under the Plan does not exceed the maximum cap on "service fees" imposed by the
NASD.

     Each Plan is a compensation plan which provides for the payment of a
specified fee without regard to the expenses actually incurred by Goldman Sachs.
If such fee exceeds Goldman Sachs' expenses, Goldman Sachs may realize a profit
from these arrangements.  The distribution fees received by Goldman Sachs under
the Plans and CDSC on Class A, Class B and Class C Shares may be sold by Goldman
Sachs as distributor to entities which provide financing for payments to

                                     B-127
<PAGE>
 
Authorized Dealers in respect of sales of Class A, Class B and Class C Shares.
To the extent such fees are not paid to such dealers, Goldman Sachs may retain
such fee as compensation for its services and expenses of distributing the
Funds' Class A, Class B and Class C Shares.

     Under each Plan, Goldman Sachs, as distributor of each Fund's Class A,
Class B and Class C Shares, will provide to the Trustees of the Trust for their
review, and the Trustees of the Trust will review at least quarterly a written
report of the services provided and amounts expended by Goldman Sachs under the
Plans and the purposes for which such services were performed and expenditures
were made.

     The Plans will remain in effect until May 1, 1999 and from year to year
thereafter, provided that such continuance is approved annually by a majority
vote of the Trustees of the Trust, including a majority of the non-interested
Trustees of the Trust who have no direct or indirect financial interest in the
Plans.  The Plans may not be amended to increase materially the amount of
distribution compensation described therein without approval of a majority of
the outstanding Class A, Class B or Class C Shares of the affected Fund and
share class.  All material amendments of a Plan must also be approved by the
Trustees of the Trust in the manner described above.  A Plan may be terminated
at any time as to any Fund without payment of any penalty by a vote of a
majority of the non-interested Trustees of the Trust or by vote of a majority of
the Class A, Class B or Class C Shares, respectively, of the applicable Fund and
share class.  If a Plan was terminated by the Trustees of the Trust and no
successor plan was adopted, the Fund would cease to make payments to Goldman
Sachs under the Plan and Goldman Sachs would be unable to recover the amount of
any of its unreimbursed expenditures.  So long as a Plan is in effect, the
selection and nomination of non-interested Trustees of the Trust may be
committed to the discretion of the non-interested Trustees of the Trust.  The
Trustees of the Trust have determined that in their judgment there is a
reasonable likelihood that the Plans will benefit the Funds and their Class A,
Class B and Class C shareholders.

     Each Fund has adopted a service plan (the "Plan") with respect to its
Service Shares which authorizes it to compensate Service Organizations for
providing certain administration services and personal and account maintenance
services to their customers who are or may become beneficial owners of such
Shares. Pursuant to the Plan, a Fund will enter into agreements with Service
Organizations which purchase Service Shares of the Fund on behalf of their
customers ("Service Agreements").  Under such Service Agreements, the Service
Organizations may perform some or all of the following services:  (a) act,
directly or through an agent, as the sole shareholder of record and nominee for
all customers; (b) maintain account records for each customer who beneficially
owns Service Shares of a Fund; (c) answer questions and handle correspondence
from customers 

                                     B-135

regarding their accounts; (d) process customer orders to purchase, redeem and
exchange Service Shares of a Fund, and handle the transmission of funds
representing the customers' purchase price or redemption proceeds; (e) issue
confirmations for transactions in shares by customers; (f) provide facilities to
answer questions from prospective and existing investors about Service Shares of
a Fund; (g) receive and answer investor correspondence, including requests for
prospectuses and statements of additional information; (h) display and make
prospectuses available on the Service Organization's premises; (i) assist
customers in completing application forms, selecting dividend and other account
options and opening custody accounts with the Service Organization; and (j) act
as liaison between customers and a Fund, including obtaining information from a
Fund, working with a Fund to correct errors and resolve problems and providing
statistical and other information to a Fund. As compensation for such services,
a Fund will pay each Service Organization a service fee in an amount up to 0.50%
(on an annualized basis) of the average daily net assets of the Service Shares
of such Fund attributable to or held in the name of such Service Organization;
provided, however, that the fee paid for personal and account maintenance
services shall not exceed 0.25% of such average daily net assets. For the fiscal
years ended October 31, 1998, October 31, 1997, and October 31, 1996 service
fees were paid by the Funds as follows:

(1)  No Service Shares of Adjustable Rate Government Fund were outstanding at

     Each Fund has adopted its Plan pursuant to Rule 12b-1 under the Act in
order to avoid any possibility that payments to the Service Organizations
pursuant to the Service Agreements might violate the Act.  Rule 12b-1, which was
adopted by the SEC under the Act, regulates the circumstances under which an
investment  company or series thereof may bear expenses associated with the
distribution of its shares.  In particular, such an investment company or series
thereof cannot engage directly or indirectly in financing any activity which is
primarily intended to result in the sale of shares issued by the company unless
it has adopted a plan pursuant to, and complies with the other requirements of,
such Rule.  The Trust believes that fees paid for the services provided in the
Plan and described above are not expenses incurred primarily for effecting the
distribution of Service Shares.  However, should such payments be deemed by a
court or the SEC to be distribution expenses, such payments would be duly
authorized by the Plan.

     The Glass-Steagall Act prohibits all entities which receive deposits from
engaging to any extent in the business of issuing, underwriting, selling or
distributing securities, although institutions such as national banks are
permitted to purchase and sell securities upon the order and for the account of
their customers.  In addition, under some state securities laws, banks and other
financial institutions purchasing Service Shares on behalf of their customers
may be required to register as dealers. Should future legislative or
administrative action or judicial or administrative decisions or interpretations
prohibit or restrict the activities of one or more of the Service Organizations
in connection with the Funds, such Service Organizations might be required to
alter materially or discontinue the services performed under their Service
Agreements.  If one or more of the Service Organizations were restricted from
effecting purchases or sales of Service Shares automatically pursuant to pre-
authorized instructions, for example, effecting such transactions on a manual
basis might affect the size and/or growth of a Fund.  Any such alteration or
discontinuance of services could require the Board of Trustees to consider
changing a Fund's method of operations or providing alternative means of
offering Service Shares of a Fund to customers of such Service Organizations, in
which case the operation of such Fund, its size and/or its growth might be
significantly altered.  It is not anticipated, however, that any alternation of
a Fund's operations would have any effect on the net asset value per share or
result in financial losses to any shareholder.

     Conflict of interest restrictions (including the Employee Retirement Income
Security Act of 1974, as amended) may apply to a Service Organization's receipt
of compensation paid by a Fund in connection with the investment of fiduciary
assets in Service Shares of such Fund.  Service Organizations, including banks
regulated by the Comptroller of the Currency, the Federal Reserve Board or the
Federal Deposit Insurance Corporation, and investment advisers and other money
managers subject to the jurisdiction of the SEC, the Department of Labor or
state securities regulators, are urged to consult their legal advisers before
investing fiduciary assets in Service Shares of the Funds.  In addition, under
some state securities laws, banks and other financial institutions purchasing
Service Shares on behalf of their customers may be required to register as
dealers.

     The Trustees, including a majority of the Trustees who are not interested
persons of the Trust and who have no direct or indirect financial interest in
the operation of the Plans or the related Service Agreements, most recently
voted to approve each Fund's Plan and Service Agreements at a meeting called for
the purpose of voting on such Plan and Service Agreements on April 22, 1998.
The Plan and Service Agreements will remain in effect until May 1, 1999 and will
continue in effect thereafter only if such continuance is specifically approved
annually by a vote of the Board of Trustees in the manner described above.  The
Plan may not be amended to increase materially the amount to be spent for the
services described therein without approval of the shareholders of the affected
Fund, and all material amendments of each Plan must also be approved by the
Board of Trustees in the manner described above.  The Plan may be terminated at
any time by a majority of the Board of Trustees as described above or by vote of
a 

                                     B-137

majority of the outstanding Service Shares of the affected Fund. The Service
Agreements may be terminated at any time, without payment of any penalty, by
vote of a majority of the Board of Trustees as described above or by a vote of a
majority of the outstanding Service Shares of the affected Fund on not more than
60 days' written notice to any other party to the Service Agreements.

     The Service Agreements will terminate automatically if assigned.  So long
as the Plan is in effect, the selection and nomination of those Trustees who are
not interested persons will be committed to the discretion of the Trust's
Nominating Committee, which consists of all of the non-interested members of the
Board of Trustees.  The Board of Trustees has determined that, in its judgment,
there is a reasonable likelihood that a Fund's Plan will benefit such Fund and
its holders of Service Shares.

     Each Fund has adopted an administration plan (the "Plan") with respect to
its Administration Shares which authorizes it to compensate Service
Organizations for providing certain account administration services to their
customers who are beneficial owners of such Shares.  Pursuant to the Plans, a
Fund enters into agreements with Service Organizations which purchase
Administration Shares on behalf of their customers ("Service Agreements").
Under such Service Agreements the Service Organizations may perform some or all
of the following services:  (a) act, directly or through an agent, as the sole

Administration Shares of a Fund and handle the transmission of funds
representing the customers' purchase price or redemption proceeds; and (e) issue
confirmations for transactions in shares by customers.  As compensation for such
services, a Fund will pay each Service Organization an account administration
fee in an amount up to 0.25% (on an annualized basis) of the average daily net
assets of the Administration Shares of such Fund attributable to or held in the
name of such Service Organization. For the fiscal years ended October 31, 1998,
1997, and 1996, administration fees accrued by the Funds were as follows:

Commercial Paper Ratings
- ------------------------

     A Standard & Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days.  The following summarizes the rating categories used by Standard &
Poor's for commercial paper:

     "A-1" - Obligations are rated in the highest category indicating that the
obligor's capacity to meet its financial commitment on the obligation is strong.
Within this category, certain obligations are designated with a plus sign (+).
This indicates that the obligor's capacity to meet its financial commitment on
these obligations is extremely strong.

     "A-2" - Obligations are somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than obligations in higher
rating categories. However, the obligor's capacity to meet its financial
commitment on the obligation is satisfactory.

     "A-3" - Obligations exhibit adequate protection parameters. However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity of the obligor to meet its financial commitment on the
obligation.

     "B" - Obligations are regarded as having significant speculative
characteristics.  The obligor currently has the capacity to meet its financial
commitment on the obligation; however, it faces major ongoing uncertainties
which could lead to the obligor's inadequate capacity to meet its financial
commitment on the obligation.

     "C" - Obligations are currently vulnerable to nonpayment and are dependent
upon favorable business, financial, and economic conditions for the obligor to
meet its financial commitment on the obligation.

     "D" - Obligations are in payment default.  The "D" rating category is used
when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless Standard and Poor's believes
that such payments will be made during such grace period.  The "D" rating will
be used upon the filing of a bankruptcy petition or the taking of a similar
action if payments on an obligation are jeopardized.

     Moody's commercial paper ratings are opinions of the ability of issuers to
repay punctually senior debt obligations not having an original maturity in
excess of one year, unless explicitly noted.  The following summarizes the
rating categories used by Moody's for commercial paper:

     "Prime-1" - Issuers (or supporting institutions) have a superior ability
for repayment of senior short-term debt obligations. Prime-1 repayment ability
will often be evidenced by many of the following characteristics: leading market
positions in well-established 

                                      A-1
<PAGE>
 
industries; high rates of return on funds employed; conservative capitalization
structure with moderate reliance on debt and ample asset protection; broad
margins in earnings coverage of fixed financial charges and high internal cash
generation; and well-established access to a range of financial markets and
assured sources of alternate liquidity.

     "Prime-2" - Issuers (or supporting institutions) have a strong ability for
repayment of senior short-term debt obligations.  This will normally be
evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation.  Capitalization characteristics, while still appropriate, may be more
affected by external conditions.  Ample alternate liquidity is maintained.

     "Prime-3" - Issuers (or supporting institutions) have an acceptable ability
for repayment of senior short-term debt obligations.  The effect of industry
characteristics and market compositions may be more pronounced.  Variability in
earnings and profitability may result in changes in the level of debt protection
measurements and may require relatively high financial leverage.  Adequate
alternate liquidity is maintained.

     "Not Prime" - Issuers do not fall within any of the Prime rating
categories.


     The three rating categories of Duff & Phelps for investment grade
commercial paper and short-term debt are "D-1," "D-2" and "D-3." Duff & Phelps
employs three designations, "D-1+," "D-1" and "D-1-," within the highest rating
category. The following summarizes the rating categories used by Duff & Phelps
for commercial paper:

     "D-1+" - Debt possesses the highest certainty of timely payment. Short-term
liquidity, including internal operating factors and/or access to alternative
sources of funds, is outstanding, and safety is just below risk-free U.S.
Treasury short-term obligations.

     "D-1" - Debt possesses very high certainty of timely payment.  Liquidity
factors are excellent and supported by good fundamental protection factors.
Risk factors are minor.

     "D-1-" - Debt possesses high certainty of timely payment. Liquidity factors
are strong and supported by good fundamental protection factors. Risk factors
are very small.

     "D-2" - Debt possesses good certainty of timely payment.  Liquidity factors
and company fundamentals are sound.  Although ongoing funding needs may enlarge
total financing requirements, access to capital markets is good. Risk factors
are small.

     "D-3" - Debt possesses satisfactory liquidity and other protection factors
qualify issues as to investment grade.  Risk factors are larger and subject to
more variation.  Nevertheless, timely payment is expected.

                                      A-2
<PAGE>
 
     "D-4" - Debt possesses speculative investment characteristics. Liquidity is
not sufficient to insure against disruption in debt service. Operating factors
and market access may be subject to a high degree of variation.

     "D-5" - Issuer has failed to meet scheduled principal and/or interest
payments.

     Fitch IBCA short-term ratings apply to debt obligations that have time
horizons of less than 12 months for most obligations, or up to three years for
U.S. public finance securities.  The following summarizes the rating categories
used by Fitch IBCA for short-term obligations:

     "F1" - Securities possess the highest credit quality.  This designation
indicates the strongest capacity for timely payment of financial commitments and
may have an added "+" to denote any exceptionally strong credit feature.

     "F2" - Securities possess good credit quality. This designation indicates a
satisfactory capacity for timely payment of financial commitments, but the
margin of safety is not as great as in the case of the higher ratings.

     "F3" - Securities possess fair credit quality.  This designation indicates
that the capacity for timely payment of financial commitments is adequate;
however, near-term adverse changes could result in a reduction to non-investment
grade.

     "B" - Securities possess speculative credit quality.  This designation
indicates minimal capacity for timely payment of financial commitments, plus
vulnerability to near-term adverse changes in financial and economic conditions.

     "C" - Securities possess high default risk. This designation indicates that
default is a real possibility and that the capacity for meeting financial
commitments is solely reliant upon a sustained, favorable business and economic
environment.

     "D" - Securities are in actual or imminent payment default.

     Thomson BankWatch short-term ratings assess the likelihood of an untimely
payment of principal and interest of debt instruments with original maturities
of one year or less.  The following summarizes the ratings used by Thomson
BankWatch:

     "TBW-1" - This designation represents Thomson BankWatch's highest category
and indicates a very high likelihood that principal and interest will be paid on
a timely basis.

     "TBW-2" - This designation represents Thomson BankWatch's second-highest
category and indicates that while the degree of safety regarding timely
repayment of principal and interest is strong, the relative degree of safety is
not as high as for issues rated "TBW-1."

                                      A-3
<PAGE>
 
     "TBW-3" - This designation represents Thomson BankWatch's lowest 
investment-grade category and indicates that while the obligation is more
susceptible to adverse developments (both internal and external) than those with
higher ratings, the capacity to service principal and interest in a timely
fashion is considered adequate.

     "TBW-4" - This designation represents Thomson BankWatch's lowest rating
category and indicates that the obligation is regarded as non-investment grade
and therefore speculative.


Corporate and Municipal Long-Term Debt Ratings
- ----------------------------------------------

     The following summarizes the ratings used by Standard & Poor's for
corporate and municipal debt:

     "AAA" - An obligation rated "AAA" has the highest rating assigned by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is extremely strong.

     "AA" - An obligation rated "AA" differs from the highest rated obligations
only in small degree.  The obligor's capacity to meet its financial commitment
on the obligation is very strong.

     "A" - An obligation rated "A" is somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher-rated categories.  However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

     "BBB" - An obligation rated "BBB" exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

     Obligations rated "BB," "B," "CCC," "CC" and "C" are regarded as having
significant speculative characteristics.  "BB" indicates the least degree of
speculation and "C" the highest.  While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.

     "BB" - An obligation rated "BB" is less vulnerable to nonpayment than other
speculative issues.  However, it faces major ongoing uncertainties or exposure
to adverse business, financial or economic conditions which could lead to the
obligor's inadequate capacity to meet its financial commitment on the
obligation.

     "B" - An obligation rated "B" is more vulnerable to nonpayment than
obligations rated "BB", but the obligor currently has the capacity to meet its
financial commitment on the 

                                      A-4
<PAGE>
 
obligation. Adverse business, financial or economic conditions will likely
impair the obligor's capacity or willingness to meet its financial commitment on
the obligation.

          "CCC" - An obligation rated "CCC" is currently vulnerable to
nonpayment, and is dependent upon favorable business, financial and economic
conditions for the obligor to meet its financial commitment on the obligation.
In the event of adverse business, financial, or economic conditions, the obligor
is not likely to have the capacity to meet its financial commitment on the
obligation.

          "CC" - An obligation rated "CC" is currently highly vulnerable to
nonpayment.

          "C" - The "C" rating may be used to cover a situation where a
bankruptcy petition has been filed or similar action has been taken, but
payments on this obligation are being continued.

          "D" - An obligation rated "D" is in payment default. The "D" rating
category is used when payments on an obligation are not made on the date due
even if the applicable grace period has not expired, unless Standard and Poor's
believes that such payments will be made during such grace period. The "D"
rating also will be used upon the filing of a bankruptcy petition or the taking
of a similar action if payments on an obligation are jeopardized.

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

          "r" - This symbol is attached to the ratings of instruments with
significant noncredit risks. It highlights risks to principal or volatility of
expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities;
obligations exposed to severe prepayment risk such as interest-only or 
principal-only mortgage securities; and obligations with unusually risky
interest terms, such as inverse floaters.

     The following summarizes the ratings used by Moody's for corporate and
municipal long-term debt:

          "Aaa" - Bonds 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 are judged to be of high quality by all standards.
Together with the "Aaa" group they comprise what are generally known as high-
grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in "Aaa" securities or 

                                      A-5
<PAGE>
 
fluctuation of protective elements may be of greater amplitude or there may be
other elements present which make the long-term risk appear somewhat larger than
the "Aaa" securities.

     "A" - Bonds 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 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," "B," "Caa," "Ca," and "C" - Bonds that possess one of these ratings
provide questionable protection of interest and principal ("Ba" indicates
speculative elements; "B" indicates a general lack of characteristics of
desirable investment; "Caa" are of poor standing; "Ca" represents obligations
which are speculative in a high degree; and "C" represents the lowest rated
class of bonds). "Caa," "Ca" and "C" bonds may be in default.

     Con. (---) - Bonds for which the security depends upon the completion of
some act or the fulfillment of some condition are rated conditionally. These are
bonds secured by (a) earnings of projects under construction; (b) earnings of
projects unseasoned in operating experience; (c) rentals which begin when
facilities are completed; or (d) payments to which some other limiting condition
attaches. Parenthetical rating denotes probable credit stature upon completion
of construction or elimination of basis of condition.

     Note: Moody's applies numerical modifiers 1, 2, and 3 in each generic
rating classification from "Aa" through "Caa". The modifier 1 indicates that the
obligation ranks in the higher end of its generic rating category; the modifier
2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the
lower end of its generic rating category.

     The following summarizes the long-term debt ratings used by Duff & Phelps
for corporate and municipal long-term debt:

     "AAA" - Debt is considered to be of the highest credit quality.  The risk
factors are negligible, being only slightly more than for risk-free U.S.
Treasury debt.

     "AA" - Debt is considered to be of high credit quality.  Protection factors
are strong.  Risk is modest but may vary slightly from time to time because of
economic conditions.

     "A" - Debt possesses protection factors which are average but adequate.
However, risk factors are more variable in periods of greater economic stress.

                                      A-6
<PAGE>
 
     "BBB" - Debt possesses below-average protection factors but such protection
factors are still considered sufficient for prudent investment.  Considerable
variability in risk is present during economic cycles.

     "BB," "B," "CCC," "DD," and "DP" - Debt that possesses one of these ratings
is considered to be below investment grade. Although below investment grade,
debt rated "BB" is deemed likely to meet obligations when due. Debt rated "B"
possesses the risk that obligations will not be met when due. Debt rated "CCC"
is well below investment grade and has considerable uncertainty as to timely
payment of principal, interest or preferred dividends. Debt rated "DD" is a
defaulted debt obligation, and the rating "DP" represents preferred stock with
dividend arrearages.

     To provide more detailed indications of credit quality, the "AA," "A,"
"BBB," "BB" and "B" ratings may be modified by the addition of a plus (+) or
minus (-) sign to show relative standing within these major categories.

     The following summarizes the ratings used by Fitch IBCA for corporate and
municipal bonds:

     "AAA" - Bonds considered to be investment grade and of the highest credit
quality.  These ratings denote the lowest expectation of credit risk and are
assigned only in case of exceptionally strong capacity for timely payment of
financial commitments.  This capacity is highly unlikely to be adversely
affected by foreseeable events.

     "AA" - Bonds considered to be investment grade and of very high credit
quality.  These ratings denote a very low expectation of credit risk and
indicate very strong capacity for timely payment of financial commitments.  This
capacity is not significantly vulnerable to foreseeable events.

     "A" - Bonds considered to be investment grade and of high credit quality.
These ratings denote a low expectation of credit risk and indicate strong
capacity for timely payment of financial commitments.  This capacity may,
nevertheless, be more vulnerable to changes in circumstances or in economic
conditions than is the case for higher ratings.

     "BBB" - Bonds considered to be investment grade and of good credit quality.
These ratings denote that there is currently a low expectation of credit risk.
The capacity for timely payment of financial commitments is considered adequate,
but adverse changes in circumstances and in economic conditions are more likely
to impair this capacity.

     "BB" - Bonds considered to be speculative. These ratings indicate that
there is a possibility of credit risk developing, particularly as the result of
adverse economic changes over time; however, business or financial alternatives
may be available to allow financial commitments to be met. Securities rated in
this category are not investment grade.

                                      A-7
<PAGE>
 
     "B" - Bonds are considered highly speculative.  These ratings indicate that
significant credit risk is present, but a limited margin of safety remains.
Financial commitments are currently being met; however, capacity for continued
payment is contingent upon a sustained, favorable business and economic
environment.

     "CCC", "CC", "C" - Bonds have high default risk.  Default is a real
possibility, and capacity for meeting financial commitments is solely reliant
upon sustained, favorable business or economic developments.  "CC" ratings
indicate that default of some kind appears probable, and "C" ratings signal
imminent default.

     "DDD," "DD" and "D" - Bonds are in default.  Securities are not meeting
obligations and are extremely speculative.  "DDD" designates the highest
potential for recovery of amounts outstanding on any securities involved and "D"
represents the lowest potential for recovery.

     To provide more detailed indications of credit quality, the Fitch IBCA
ratings from and including "AA" to "B" may be modified by the addition of a plus
(+) or minus (-) sign to show relative standing within these major rating
categories.

     Thomson BankWatch assesses the likelihood of an untimely repayment of
principal or interest over the term to maturity of long term debt and preferred
stock which are issued by United States commercial banks, thrifts and non-bank
banks; non-United States banks; and broker-dealers.  The following summarizes
the rating categories used by Thomson BankWatch for long-term debt ratings:

     "AAA" - This designation indicates that the ability to repay principal and
interest on a timely basis is extremely high.

     "AA" - This designation indicates a very strong ability to repay principal
and interest on a timely basis, with limited incremental risk compared to issues
rated in the highest category.

     "A" - This designation indicates that the ability to repay principal and
interest is strong.  Issues rated "A" could be more vulnerable to adverse
developments (both internal and external) than obligations with higher ratings.

     "BBB" - This designation represents the lowest investment-grade category
and indicates an acceptable capacity to repay principal and interest. Issues
rated "BBB" are more vulnerable to adverse developments (both internal and
external) than obligations with higher ratings.

     "BB," "B," "CCC," and "CC," - These designations are assigned by Thomson
BankWatch to non-investment grade long-term debt.  Such issues are regarded as
having speculative characteristics regarding the likelihood of timely payment of
principal and interest.  "BB" indicates the lowest degree of speculation and
"CC" the highest degree of speculation.

                                      A-8
<PAGE>
 
     "D" - This designation indicates that the long-term debt is in default.

     PLUS (+) OR MINUS (-) - The ratings from "AAA" through "CC" may include a
plus or minus sign designation which indicates where within the respective
category the issue is placed.


Municipal Note Ratings
- ----------------------

     A Standard and Poor's rating reflects the liquidity concerns and market
access risks unique to notes due in three years or less. The following
summarizes the ratings used by Standard & Poor's Ratings Group for municipal
notes:

     "SP-1" - The issuers of these municipal notes exhibit a strong capacity to
pay principal and interest. Those issues determined to possess very strong
characteristics are given a plus (+) designation.

     "SP-2" - The issuers of these municipal notes exhibit satisfactory capacity
to pay principal and interest, with some vulnerability to adverse financial and
economic changes over the term of the notes.

     "SP-3" - The issuers of these municipal notes exhibit speculative capacity
to pay principal and interest.

     Moody's ratings for state and municipal notes and other short-term loans
are designated Moody's Investment Grade ("MIG") and variable rate demand
obligations are designated Variable Moody's Investment Grade ("VMIG"). Such
ratings recognize the differences between short-term credit risk and long-term
risk. The following summarizes the ratings by Moody's Investors Service, Inc.
for short-term notes:

     "MIG-1"/"VMIG-1" - This designation denotes best quality.  There is present
strong protection by established cash flows, superior liquidity support or
demonstrated broad-based access to the market for refinancing.

     "MIG-2"/"VMIG-2" - This designation denotes high quality, with margins of
protection that are ample although not so large as in the preceding group.

     "MIG-3"/"VMIG-3" - This designation denotes favorable quality, with all
security elements accounted for but lacking the undeniable strength of the
preceding grades.  Liquidity and cash flow protection may be narrow and market
access for refinancing is likely to be less well established.

                                      A-9
<PAGE>
 
     "MIG-4"/"VMIG-4" - This designation denotes adequate quality.  Protection
commonly regarded as required of an investment security is present and although
not distinctly or predominantly speculative, there is specific risk.

     "SG" - This designation denotes speculative quality. Debt instruments in
this category lack of margins of protection.

     Fitch IBCA and Duff & Phelps use the short-term ratings described under
Commercial Paper Ratings for municipal notes.

                                      A-10

 (a) TBA (To Be Assigned) securities are purchased on a forward commitment
     basis with an approximate (generally + /--2.5%) principal amount and no
     definite maturity date. The actual principal amount and maturity date
     will be determined upon settlement when the specific mortgage pools are
     assigned.
 (b) Represents security with notional or nominal principal amount. The actual
     effective yield of this security is different than the stated coupon due
     to the amortization of related premiums.
 (c) Variable rate security. Coupon rate disclosed is that which is in effect
     at October 31, 1998.
 (d) The interest rate disclosed for these securities represents effective
     yield to maturity.
 (e) Security is exempt from registration under rule 144A of the Securities
     Act of 1933. Such securities may be resold, normally to qualified
     institutional buyers in transactions exempt from registration. Total
     market value of the Rule 144A securities amounted to $2,055,700 as of
     October 31, 1998.
 (f) Portions of these securities are being segregated for open TBA purchases,
     forward sale contract, open futures contracts and futures margin
     requirements.
 (g) The amount stated also represents aggregate cost for federal income tax
     purposes.
 (h) Each Euro Dollar Contract represents $1,000,000 in notional par value.
     Each 5-Year and 10-Year U.S. Treasury Note contract represents $100,000
     in notional par value. Each 2-Year U.S. Treasury Note contract represents
     $200,000 in notional par value. The total notional amount and market
     value at risk are $95,400,000 and 38,596,038, respectively. The
     determination of notional amounts as presented here are indicative only
     of volume of activity and not a measure of market risk.

investments in that category as a percentage of total net assets.

GOLDMAN SACHS TAXABLE INVESTMENT GRADE FUNDS
 
Notes to Financial Statements
October 31, 1998
 
 1. ORGANIZATION
 
 Goldman Sachs Trust (the "Trust") is a Delaware business trust registered un-
 der the Investment Company Act of 1940 (as amended) as an open-end, manage-
 ment investment company. The Trust includes Goldman Sachs Adjustable Rate
 Government Fund (Adjustable Rate Government), Goldman Sachs Short Duration
 Government Fund (Short Duration Government), Goldman Sachs Government Income
 Fund (Government Income), Goldman Sachs Core Fixed Income Fund (Core Fixed
 Income) and Goldman Sachs Global Income Fund (Global Income), collectively,
 "the Funds" or individually a "Fund." Adjustable Rate Government, Short Dura-
 tion Government, Government Income, and Core Fixed Income are diversified
 portfolios of the Trust whereas Global Income is a non-diversified portfolio.
 Adjustable Rate Government offers four classes of shares -- Class A, Institu-
 tional, Administration and Service. Government Income and Global Income offer
 five classes of shares -- Class A, Class B, Class C, Institutional and Serv-
 ice. Short Duration Government and Core Fixed Income offer six classes of
 shares -- Class A, Class B, Class C, Institutional, Administration and Serv-
 ice.
 
 2. SIGNIFICANT ACCOUNTING POLICIES
 
 The following is a summary of significant accounting policies consistently
 followed by the Funds. The preparation of financial statements in conformity
 with generally accepted accounting principles requires management to make es-
 timates and assumptions that may affect the reported amounts. Certain reclas-
 sifications have been made to the prior period's amounts to conform with the
 current period presentation. Such reclassifications have no effect on previ-
 ously reported net asset values of the Fund.
 
 A. Investment Valuation -- Portfolio securities for which accurate market
 quotations are readily available are valued on the basis of quotations fur-
 nished by a pricing service or provided by dealers in such securities. Port-
 folio securities for which accurate market quotations are not readily
 available are valued based on yield equivalents, pricing matrices or other
 sources, under valuation procedures established by the Trust's Board of
 Trustees. Short-term debt obligations maturing in sixty days or less are val-
 ued at amortized cost.
 
 B. Security Transactions and Investment Income -- Security transactions are
 recorded on trade date. Realized gains and losses on sales of portfolio secu-
 rities are calculated using the identified cost basis. Interest income is re-
 corded on the basis of interest accrued. Premiums on interest-only securities
 and on collateralized mortgage obligations with nominal principal amounts are
 amortized, on an effective yield basis, over the expected lives of the re-
 spective securities.
   Certain mortgage security paydown gains and losses are taxable as ordinary
 income. Such paydown gains and losses increase or decrease taxable ordinary
 income available for distribution and are classified as interest income in
 the accompanying Statements of Operations. Original issue discounts ("OID")
 on debt securities are amortized to interest income over the life of the se-
 curity with a corresponding increase in the cost basis of that security. OID
 amortization on mortgage backed REMIC securities is initially recorded based
 on estimates of principal paydowns using the most recent OID factors avail-
 able from the issuer. Recorded amortization amounts are adjusted when actual
 OID factors are received. Market discounts and market premiums on debt secu-
 rities, other than mortgage backed REMIC securities, are amortized to inter-
 est income over the life of the security with a corresponding adjustment in
 the cost basis of that security for Core Fixed Income. Global Income amor-
 tizes only market discounts on debt securities other than REMIC mortgage
 backed securities.

 C. Federal Taxes -- It is each Fund's policy to comply with the requirements
 of the Internal Revenue Code applicable to regulated investment companies and
 to distribute each year substantially all of its investment company taxable
 and tax- exempt income and capital gains to its shareholders. Accordingly, no
 federal tax provisions are required.
   The characterization of distributions to shareholders for financial report-
 ing purposes is determined in accordance with income tax rules. Therefore,
 the source of a portfolio's distributions may be shown in the accompanying
 financial statements as either from or in excess of net investment income or
 net realized gain on investment transactions, or from paid-in-capital, de-
 pending on the type of book/tax differences that may exist as well as timing
 differences associated with having different book and tax year ends.
   Adjustable Rate Government and Short Duration Government, at their most re-
 cent tax year-ends of December 31, 1997, had approximately the following
 amounts of capital loss carryforward for U.S. federal tax purposes. These
 amounts are available to be carried forward to offset future capital gains to
 the extent permitted by applicable laws or regulations.

 D. Expenses -- Expenses incurred by the Trust that do not specifically relate
 to an individual Fund of the Trust are allocated to the Funds based on the
 nature of the expense.
   Class A, Class B and Class C shareholders of the Funds bear all expenses
 and fees relating to their respective distribution and service plans. Share-
 holders of Service and Administration shares bear all expenses and fees paid
 to service organizations for their services with respect to such shares. Ef-
 fective October 1, 1998, each class of shares of the Funds now separately
 bear their respective class-specific transfer agency fees.
 
 E. Deferred Organization Expenses -- Organization-related costs are being am-
 ortized on a straight-line basis over a period of five years. The amortiza-
 tion costs of Adjustable Rate Government, Short Duration Government,
 Government Income and Global Income are fully amortized.
 
 F. Foreign Currency Translations -- The books and records of the Funds are
 maintained in U.S. dollars. Amounts denominated in foreign currencies are
 translated into U.S. dollars on the following basis: (i) investment valua-
 tions, foreign currency and other assets and liabilities initially expressed
 in foreign currencies are converted each business day into U.S. dollars based
 upon current exchange rates; (ii) purchases and sales of foreign investments,
 income and expenses are converted into U.S. dollars based upon currency ex-
 change rates prevailing on the respective dates of such transactions.
   Net realized and unrealized gain (loss) on foreign currency transactions
 will represent: (i) foreign exchange gains and losses from the sale and hold-
 ings of foreign currencies and sale of investments; (ii) gains and losses be-
 tween trade date and settlement date on investment securities transactions
 and forward exchange contracts; and (iii) gains and losses from the differ-
 ence between amounts of interest recorded and the amounts actually received.
 
 G. Forward Foreign Currency Exchange Contracts -- Core Fixed Income and
 Global Income may enter into forward foreign currency exchange contracts for
 the purchase or sale of a specific foreign currency at a fixed price on a fu-
 ture date as a hedge or cross-hedge against either specific transactions or
 portfolio positions. Core Fixed Income and Global Income may also purchase
 and sell forward contracts to seek to increase total return. All commitments
 are "marked-to-market" daily at
 
                                                                              47
<PAGE>
 
GOLDMAN SACHS TAXABLE INVESTMENT GRADE FUNDS
 
Notes to Financial Statements

 the applicable translation rates and any resulting unrealized gains or losses
 are recorded in the Funds' financial statements. The Funds record realized
 gains or losses at the time a forward contract is offset by entry into a
 closing transaction or extinguished by delivery of the currency. Risks may
 arise upon entering into these contracts from the potential inability of
 counterparties to meet the terms of their contracts and from unanticipated
 movements in the value of a foreign currency relative to the U.S. dollar.
 
 H. Futures Contracts -- The Funds may enter into futures transactions to
 hedge against changes in interest rates, securities prices, currency exchange
 rates (in the case of Core Fixed Income and Global Income) or to seek to in-
 crease total return.
   Upon entering into a futures contract, the Funds are required to deposit
 with a broker an amount of cash or securities equal to the minimum "initial
 margin" requirement of the associated futures exchange. Subsequent payments
 for futures contracts ("variation margin") are paid or received by the Funds
 daily, dependent on the daily fluctuations in the value of the contracts, and
 are recorded for financial reporting purposes as unrealized gains or losses.
 When contracts are closed, the Funds realize a gain or loss which is reported
 in the Statements of Operations.
   The use of futures contracts involve, to varying degrees, elements of mar-
 ket and counterparty risk which may exceed the amounts recognized in the
 Statements of Assets and Liabilities. Changes in the value of the futures
 contract may not directly correlate with changes in the value of the under-
 lying securities. This risk may decrease the effectiveness of the Funds'
 hedging strategies and potentially result in a loss.
 
 I. Option Accounting Principles -- When the Funds write call or put options,
 an amount equal to the premium received is recorded as an asset and as an
 equivalent liability. The amount of the liability is subsequently marked-to-
 market to reflect the current market value of the option written. When a
 written option expires on its stipulated expiration date or the Funds enter
 into a closing purchase transaction, the Funds realize a gain or loss without
 regard to any unrealized gain or loss on the underlying security, and the li-
 ability related to such option is extinguished. When a written call option is
 exercised, the Funds realize a gain or loss from the sale of the underlying
 security, and the proceeds of the sale are increased by the premium origi-
 nally received. When a written put option is exercised, the amount of the
 premium originally received will reduce the cost of the security which the
 Funds purchase upon exercise. There is a risk of loss from a change in value
 of such options which may exceed the related premiums received.
   Upon the purchase of a call option or a protective put option by the Funds,
 the premium paid is recorded as an investment and subsequently marked-to-mar-
 ket to reflect the current market value of the option. If an option which the
 Funds have purchased expires on the stipulated expiration date, the Funds
 will realize a loss in the amount of the cost of the option. If the Funds en-
 ter into a closing sale transaction, the Funds will realize a gain or loss,
 depending on whether the sale proceeds for the closing sale transaction are
 greater or less than the cost of the option. If the Funds exercise a pur-
 chased put option, the Funds will realize a gain or loss from the sale of the
 underlying security, and the proceeds from such sale will be decreased by the
 premium originally paid. If the Funds exercise a purchased call option, the
 cost of the security which the Funds purchase upon exercise will be increased
 by the premium originally paid.
 
 J. Mortgage Dollar Rolls -- The Funds may enter into mortgage "dollar rolls"
 in which the Funds sell securities in the current month for delivery and si-
 multaneously contract with the same counterparty to repurchase similar (same
 type, coupon and maturity) but not identical securities on a specified future
 date. For financial reporting and tax reporting purposes, the Funds treat
 mortgage dollar rolls as two separate transactions; one involving the pur-
 chase of a security and a separate transaction involving a sale.

 3. AGREEMENTS
 
 Pursuant to the Investment Management Agreements (the "Agreements"), Goldman
 Sachs Funds Management, L.P. ("GSFM"), an affiliate of Goldman, Sachs & Co.
 ("Goldman Sachs"), serves as the investment adviser for Adjustable Rate Gov-
 ernment and Short Duration Government. Goldman Sachs Asset Management
 ("GSAM"), a separate operating division of Goldman Sachs, serves as the in-
 vestment adviser for Government Income and Core Fixed Income. Goldman Sachs
 Asset Management International ("GSAMI"), an affiliate of GSAM, serves as the
 investment adviser for Global Income. Under the Agreements, the respective
 adviser, subject to the general supervision of the Trust's Board of Trustees,
 manages the Funds' portfolios. As compensation for the services rendered pur-
 suant to the Agreements, the assumption of the expenses related thereto and
 administering the Funds' business affairs, including providing facilities,
 the adviser is entitled to a fee, computed daily and payable monthly at an
 annual rate equal to .40%, .50%, .65%, .40% and .90% of average daily net as-
 sets of Adjustable Rate Government, Short Duration Government, Government In-
 come, Core Fixed Income and Global Income, respectively.
   Each adviser has voluntarily agreed to limit "Other Expenses", with the ex-
 ception of Adjustable Rate Government, (excluding management fees, distribu-
 tion and service fees, taxes, interest, brokerage, litigation, Administrative
 and Service share fees, indemnification costs and other extraordinary ex-
 penses and with respect to Global Income, transfer agent fees) to the extent
 that such expenses exceeded .05%, .00%, .05% and .06% of the average daily
 net assets of Short Duration Government, Government Income, Core Fixed Income
 and Global Income, respectively. Effective September 1, 1998 for Global In-
 come and October 1, 1998 for Adjustable Rate Government, Short Duration Gov-
 ernment, Government Income and Core Fixed Income, these expense limitations
 were modified to .00%, .05%, .00%, .00% and .10% (excluding management fees,
 distribution and service fees, transfer agent fees, taxes, interest, broker-
 age, litigation, administration and service share fees, indemnification costs
 and extraordinary expenses), respectively.
   Goldman Sachs serves as Distributor of the shares of the Funds pursuant to
 a Distribution Agreement. Goldman Sachs may receive a portion of the Class A
 sales load and Class B and Class C contingent deferred sales charges and has
 advised the Funds that it retained approximately $28,000, $157,000, $212,000,
 $82,000 and $133,000 for the year ended October 31, 1998 for Adjustable Rate
 Government, Short Duration Government, Government Income, Core Fixed Income
 and Global Income, respectively.
   The Trust, on behalf of each Fund, had adopted Distribution Plans (the
 "Distribution Plans") pursuant to Rule 12b-1. Under the Distribution Plans,
 Goldman Sachs was entitled to a quarterly fee from each Fund for distribution
 services equal, on an annual basis, to .25%, .75% and .75% of the average
 daily net assets attributable to Class A, Class B and Class C shares, respec-
 tively.
   The Trust, on behalf of each Fund, had adopted Authorized Dealer Service
 Plans (the "Dealer Service Plans") pursuant to which Goldman Sachs and Autho-
 rized Dealers were compensated for providing personal and account maintenance
 services. Each Fund paid a fee under the Dealer Service Plan equal, on an an-
 nual basis, up to .25% of its average daily net assets attributable to Class
 A, Class B and Class C shares.
   Effective September 1, 1998 for Global Income and October 1, 1998 for Ad-
 justable Rate Government, Short Duration Government, Government Income and
 Core Fixed Income, the Distribution Plans and Dealer Service Plans were com-
 bined into Distribution and Service plans. Under the Distribution and Service
 Plans, Goldman Sachs and/or Authorized Dealers are entitled to a monthly fee
 from each fund for distribution services and shareholder maintenance equal,
 on an annual basis, to .50%, 1.00% and 1.00% for Global Income and .25%,
 1.00% and 1.00% of each of the other funds' average daily net assets attrib-
 utable to Class A, Class B and Class C shares, respectively.
   Goldman Sachs also serves as Transfer Agent of the Funds for a fee. Effec-
 tive September 1, 1998 for Global Income and October 1, 1998 for Adjustable
 Rate Government, Short Duration Government, Government Income and Core Fixed
 Income, the fees charged for such transfer agency services are calculated
 daily and payable monthly at an annual rate as
 
                                                                              49

 follows: .19% of average daily net assets for Class A, Class B and Class C
 shares and .04% of average daily net assets for Institutional, Service and
 Administration Shares.
   The Trust, on behalf of the Funds, has adopted Service Plans. In addition,
 the Trust, on behalf of Adjustable Rate Government, Short Duration Government
 and Core Fixed Income, has adopted Administration Plans. These plans allow
 for Service shares and Administration shares, respectively, to compensate
 service organizations for providing varying levels of account administration
 and shareholder liaison services to their customers who are beneficial owners
 of such shares. The Service and Administration Plans provide for compensation
 to the service organizations in an amount up to .50% and .25% (on an
 annualized basis), respectively, of the average daily net asset value of the
 respective shares.
   For the year ended October 31, 1998, the advisors and distributor have vol-
 untarily agreed to waive certain fees and reimburse other expenses as follows

Notes to Financial Statements
October 31, 1998
 
   The contractual amounts of forward foreign currency exchange contracts do
 not necessarily represent the amounts potentially subject to risk. The mea-
 surement of the risks associated with these instruments is meaningful only
 when all related and offsetting transactions are considered. At October 31,
 1998, Global Income had sufficient cash and/or securities to cover any com-
 mitments under these contracts.
   Global Income has recorded a "Receivable for forward foreign currency ex-
 change contracts" and "Payable for forward foreign currency exchange con-
 tracts" resulting from open and closed but not settled forward foreign
 currency exchange contracts of $1,802,980 and $4,943,283, respectively, in
 the accompanying Statement of Assets and Liabilities. Included in the Global
 Income "Receivable and Payable for forward foreign currency exchange con-
 tracts" are $588,209 and $1,344,045, respectively, related to forward con-
 tracts closed but not settled as of October 31, 1998.
   For the year ended October 31, 1998, Adjustable Rate Government, Short Du-
 ration Government, Government Income, Core Fixed Income and Global Income in-
 curred commission expenses of approximately $54,000, $26,000, $8,000, $9,000
 and $8,000, respectively, in connection with futures contracts entered into
 with Goldman Sachs. At October 31, 1998, Goldman Sachs was owed approximately
 $157,000, $131,000, $130,000 and $128,000 from Adjustable Rate Government,
 Short Duration Government, Government Income and Core Fixed Income, respec-
 tively, related to variation margin on futures contracts. Goldman Sachs owed
 approximately $30,000 to Global Income related to variation margin on futures
 contracts.
 
 5. REPURCHASE AGREEMENTS
 
 During the term of a repurchase agreement, the value of the underlying secu-
 rities, including accrued interest, is required to equal or exceed the value
 of the repurchase agreement. The underlying securities for all repurchase
 agreements are held in safekeeping at the Funds' custodian.
 
 6. JOINT REPURCHASE AGREEMENT ACCOUNT
 
 The Funds, together with other registered investment companies having manage-
 ment agreements with GSFM, GSAMI and GSAM or their affiliates, transfer
 uninvested cash into joint accounts, the daily aggregate balance of which is
 invested in one or more repurchase agreements.
   At October 31, 1998, Adjustable Rate Government, Short Duration Government,
 Government Income and Core Fixed Income had undivided interests in the repur-
 chase agreements in the following joint account which equaled $43,700,000,
 $6,400,000, $14,600,000 and $22,300,000, respectively, in principal amount.
 At October 31, 1998, the following repurchase agreements held in this joint
 account were fully collateralized by U.S. Treasury and agency obligations.

 7. LINE OF CREDIT FACILITY
 
 The Funds participate in a $250,000,000 uncommitted, unsecured revolving line
 of credit facility. In addition, Global Income participates in a $50,000,000
 committed, unsecured revolving line of credit facility. Both facilities are
 to be used solely for temporary or emergency purposes. Under the most re-
 strictive arrangement, each Fund must own securities having a market value in
 excess of 300% of the total bank borrowings. The interest rate on the
 borrowings is based on the federal funds rate. The committed facility also
 requires a fee to be paid by the Fund based on the amount of the commitment
 which has not been utilized. During the year ended October 31, 1998, the
 Funds did not have any borrowings under these facilities.
 
 8. OTHER MATTERS
 
 As of October 31, 1998, the Goldman, Sachs & Co. Profit Sharing Master Trust
 was the beneficial owner of approximately 20% and 15% of the outstanding
 shares of Short Duration Government and Global Income, respectively. In addi-
 tion, the Goldman Sachs Balanced Strategy Portfolio was the beneficial owner
 of approximately 14%, 3% and 1% of the outstanding shares of Short Duration
 Government, Global Income and High Yield, respectively. The Goldman Sachs
 Growth and Income Strategy Portfolio was the beneficial owner of approxi-
 mately 19%, 15% and 5% of the outstanding shares of Core Fixed Income, Global
 Income and High Yield, respectively. The Goldman Sachs Growth Strategy Port-
 folio was the beneficial owner of approximately 6%, 4% and 2% of Core Fixed
 Income, Global Income and High Yield, respectively.
 
 9. CERTAIN RECLASSIFICATIONS
 
 In accordance with Statement of Position 93-2, Adjustable Rate Government has
 reclassified $938,738 and $1,410,151 from paid-in capital to accumulated dis-
 tributions in excess of net investment income and accumulated net realized
 loss, respectively. Short Duration Government has reclassified $33,684 and
 $8,196 to paid-in capital and accumulated undistributed net investment in-
 come, respectively, from accumulated net realized loss. Government Income has
 reclassified $1,659 from paid-in capital to accumulated distributions in ex-
 cess of net investment income and an additional $164,196 and $15,707 from ac-
 cumulated net realized gain to accumulated distributions in excess of net
 investment income and paid-in capital, respectively. Core Fixed Income has
 reclassified $24,095 and $444,061 from paid-in capital and accumulated net
 realized gain, respectively, to accumulated distributions in excess of net
 investment income. In addition, Core Fixed Income has reclassified $2,294 and
 $19,060 from accumulated distributions in excess of net investment income to
 paid-in capital and accumulated net realized gain, respectively. Global In-
 come has reclassified $6,564,667 from accumulated undistributed net invest-
 ment income to accumulated net realized gain and an additional $30,213 and
 $726,330 from paid-in capital to accumulated undistributed net investment in-
 come and accumulated net realized gain, respectively.
 
 These reclassifications have no impact on the net asset value of the Funds
 and are designed to present the Fund's capital accounts on a tax basis.

 October 31, 1998, and the related statements of operations and the statements
 of changes in net assets and the financial highlights for the periods pre-
 sented. These financial statements and the financial highlights are the re-
 sponsibility of the Funds' management. Our responsibility is to express an
 opinion on these financial statements and the financial highlights based on
 our audits.
 
 We conducted our audits in accordance with generally accepted auditing stan-
 dards. Those standards require that we plan and perform the audit to obtain
 reasonable assurance about whether the financial statements and the financial
 highlights are free of material misstatement. An audit includes examining, on
 a test basis, evidence supporting the amounts and disclosures in the finan-
 cial statements. Our procedures included confirmation of securities owned as
 of October 31, 1998 by correspondence with the custodian and brokers. An au-
 dit also includes assessing the accounting principles used and significant
 estimates made by management, as well as evaluating the overall financial
 statement presentation. We believe that our audits provide a reasonable basis
 for our opinion.
 
 In our opinion, the financial statements and the financial highlights re-
 ferred to above present fairly, in all material respects, the financial posi-
 tion of Goldman Sachs Adjustable Rate Government Fund, Short Duration
 Government Fund, Government Income Fund, Core Fixed Income Fund and Global
 Income Fund as of October 31, 1998, the results of their operations and the
 changes in their net assets and the financial highlights for the periods pre-
 sented, in conformity with generally accepted accounting principles.

Notes to Financial Statements
October 31, 1998
 
 1. ORGANIZATION
 
 Goldman Sachs Trust (the "Trust") is a Delaware business trust registered un-
 der the Investment Company Act of 1940 (as amended) as an open-end, manage-
 ment investment company. The Trust includes the Goldman Sachs High Yield Fund
 (the "Fund"). The Fund is a diversified portfolio offering five classes of
 shares -- Class A, Class B, Class C, Institutional and Service.
   The Fund invests primarily in non-investment grade fixed-income securities
 which are considered predominantly speculative by traditional investment
 standards. In some cases, these obligations may be highly speculative and
 have poor prospects for reaching investment grade standing. Non-investment
 grade fixed-income securities and unrated securities of comparable credit
 quality (commonly known as "junk bonds") are subject to the increased risk of
 an issuer's inability to meet principal and interest obligations. These secu-
 rities, also referred to as high yield securities, may be subject to greater
 price volatility due to such factors as specific corporate developments, in-
 terest rate sensitivity, negative perceptions of the junk bond markets gener-
 ally and less secondary market liquidity.
 
 2. SIGNIFICANT ACCOUNTING POLICIES
 
 The following is a summary of significant accounting policies consistently
 followed by the Fund. The preparation of financial statements in conformity
 with generally accepted accounting principles requires management to make es-
 timates and assumptions that may affect the reported amounts. Certain reclas-
 sifications have been made to the prior period's amounts to conform with the
 current period presentation. Such reclassifications have no effect on previ-
 ously reported net asset values of the Fund.
 
 A. Investment Valuation -- Portfolio securities for which accurate market
 quotations are readily available are valued on the basis of quotations fur-
 nished by a pricing service or provided by dealers in such securities. Port-
 folio securities for which accurate market quotations are not readily
 available are valued based on yield equivalents, pricing matrices or other
 sources, under valuation procedures established by the Trust's Board of
 Trustees. Short-term debt obligations maturing in sixty days or less are val-
 ued at amortized cost.
 
 B. Security Transactions and Investment Income -- Security transactions are
 recorded on the trade date. Realized gains and losses on sales of portfolio
 securities are calculated using the identified cost basis. Interest income is
 recorded on the basis of interest accrued. Market discounts and market premi-
 ums on debt securities, other than mortgage backed securities, are amortized
 to interest income over the life of the security with a corresponding adjust-
 ment in the cost basis of that security.
 
 C. Federal Taxes -- It is the Fund's policy to comply with the requirements
 of the Internal Revenue Code applicable to regulated investment companies and
 to distribute each year substantially all of its investment company taxable
 income and capital gains to its shareholders. Accordingly, no federal tax
 provision is required.
   The characterization of distributions to shareholders for financial report-
 ing purposes is determined in accordance with income tax rules. Therefore,
 the source of the portfolio's distributions may be shown in the accompanying
 financial statements as either from or in excess of net investment income or
 net realized gain on investment transactions, or from paid-in capital, de-
 pending on the type of book/tax differences that may exist.
   The Fund, at its most recent tax year-end of October 31, 1998 had approxi-
 mately $5,746,000 capital loss carryforwards expiring in 2006 for U.S. fed-
 eral tax purposes. This amount is available to be carried forward to offset
 future capital gains to the extent permitted by applicable laws or regula-
 tions.
 
 D. Expenses -- Expenses incurred by the Trust that do not specifically relate
 to an individual Fund of the Trust are allocated to the Funds based on the
 nature of the expense.
   Class A, Class B and Class C shareholders of the Fund bear all expenses and
 fees relating to their respective distribution and service plans. Sharehold-
 ers of Service shares bear all expenses and fees paid to service organiza-
 tions for their services with respect to such shares. Each class of shares
 separately bears its respective class-specific transfer agency fees.
 
 E. Deferred Organization Expenses -- Organization-related costs are being am-
 ortized on a straight-line basis over a period of five years.
 
 F. Foreign Currency Translations -- The books and records of the Fund are
 maintained in U.S. dollars. Amounts denominated in foreign currencies are
 translated into U.S. dollars on the following basis (i) investment valua-
 tions, foreign currency and other assets and liabilities initially expressed
 in foreign currencies are converted each business day into U.S. dollars based
 upon current exchange rates; (ii) purchases and sales of foreign investments,
 income and expenses are converted into U.S. dollars based upon currency ex-
 change rates prevailing on the respective dates of such transactions.
   Net realized and unrealized gain (loss) on foreign currency transactions
 will represent: (i) gains and losses from the sale and holdings of foreign
 currencies and sale of investments; (ii) gains and losses between trade date
 and settlement date on
 
                                                                              13

 investment securities transactions and forward exchange contracts; and (iii)
 gains and losses from the difference between amounts of interest and foreign
 withholding taxes recorded and the amounts actually received.
 
 G. Forward Foreign Currency Exchange Contracts -- The Fund may enter into
 forward foreign currency exchange contracts for the purchase or sale of a
 specific foreign currency at a fixed price on a future date as a hedge or
 cross-hedge against either specific transactions or portfolio positions. The
 Fund may also purchase and sell forward contracts to seek to increase total
 return. All commitments are "marked-to-market" daily at the applicable trans-
 lation rates and any resulting unrealized gains or losses are recorded in the
 Fund's financial statements. The Fund records realized gains or losses at the
 time the forward contract is offset by entry into a closing transaction or
 extinguished by delivery of the currency. Risks may arise upon entering into
 these contracts from the potential inability of counterparties to meet the
 terms of their contracts and from unanticipated movements in the value of a
 foreign currency relative to the U.S. dollar.
 
 H. Futures Contracts -- The Fund may enter into futures transactions to hedge
 against changes in interest rates, securities prices, currency exchange rates
 or to seek to increase total return.
   Upon entering into a futures contract, the Fund is required to deposit with
 a broker an amount of cash or securities equal to the minimum "initial mar-
 gin" requirement of the associated futures exchange. Subsequent payments for
 futures contracts ("variation margin") are paid or received by the Fund dai-
 ly, dependent on the daily fluctuations in the value of the contracts, and
 are recorded for financial reporting purposes as unrealized gains or losses.
 When contracts are closed, the Fund realizes a gain or loss which is reported
 in the Statement of Operations.
   The use of futures contracts involve, to varying degrees, elements of mar-
 ket and counterparty risk which may exceed the amounts recognized in the
 Statement of Assets and Liabilities. Changes in the value of the futures con-
 tract may not directly correlate with changes in the value of the underlying
 securities. This risk may decrease the effectiveness of the Fund's hedging
 strategies and potentially result in a loss.
 
 I. Option Accounting Principles -- When the Fund writes call or put options,
 an amount equal to the premium received is recorded as an asset and as an
 equivalent liability. The amount of the liability is subsequently marked-to-
 market to reflect the current market value of the option written. When a
 written option expires on its stipulated expiration date or the Fund enters
 into a closing purchase transaction, the Fund realizes a gain or loss without
 regard to any unrealized gain or loss on the underlying security, and the li-
 ability related to such option is extinguished. When a written call option is
 exercised, the Fund realizes a gain or loss from the sale of the underlying
 security, and the proceeds of the sale are increased by the premium origi-
 nally received. When a written put option is exercised, the amount of the
 premium originally received will reduce the cost of the security which the
 Fund purchases upon exercise. There is a risk of loss from a change in value
 of such options which may exceed the related premiums received.
   Upon the purchase of a call option or a protective put option by the Fund,
 the premium paid is recorded as an investment and subsequently marked-to-mar-
 ket to reflect the current market value of the option. If an option which the
 Fund has purchased expires on the stipulated expiration date, the Fund will
 realize a loss in the amount of the cost of the option. If the Fund enters
 into a closing sale transaction, the Fund will realize a gain or loss, de-
 pending on whether the sale proceeds for the closing sale transaction are
 greater or less than the cost of the option. If the Fund exercises a pur-
 chased put option, the Fund will realize a gain or loss from the sale of the
 underlying security, and the proceeds from such sale will be decreased by the
 premium originally paid. If the Fund exercises a purchased call option, the
 cost of the security which the Fund purchases upon exercise will be increased
 by the premium originally paid.
 
 3. AGREEMENTS
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as the Fund's investment ad-
 viser pursuant to an Investment Management Agreement (the "Agreement"). Under
 the Agreement, GSAM, subject to the general supervision of the Trust's Board
 of Trustees, manages the Fund's portfolio. As compensation for the services
 rendered pursuant to the Agreement, the assumption of the expenses related
 thereto and administering the Fund's business affairs, including providing
 facilities, GSAM is entitled to a fee, computed daily and payable monthly at
 an annual rate equal to .70% of average daily net assets of the Fund. For the
 year ended October 31, 1998, GSAM voluntarily agreed to waive approximately
 $70,000 of its management fee. This waiver was discontinued as of March 16,
 1998.
   GSAM voluntarily agreed to limit "Other Expenses" for the Fund (excluding
 management fees, Service share fees, distribution and services fees, taxes,
 interest, brokerage, litigation, indemnification costs, transfer agent fees
 and other extraordinary expenses) through September 30, 1998 to the extent
 such expenses exceeded .09% of the average daily net assets of the Fund. Ef-
 fective October 1, 1998, this expense limitation was modified until further
 notice to .02% of the average daily net assets of the Fund. For the year
 ended October 31, 1998, Goldman Sachs reimbursed approximately $92,000. At
 October 31, 1998, approximately $92,000 is owed to the Fund.

   Goldman Sachs serves as the Distributor of shares of the Funds pursuant to
 a Distribution Agreement. Goldman Sachs may receive a portion of the Class A
 sales load and Class B and Class C contingent deferred sales charges and has
 advised the Fund that it retained approximately $1,419,000 for the year ended
 October 31, 1998.
   The Trust, on behalf of the Fund, had adopted Distribution Plans (the "Dis-
 tribution Plans") pursuant to Rule 12b-1. Under the Distribution Plans,
 Goldman Sachs was entitled to a quarterly fee from the Fund for distribution
 services equal, on an annual basis, to .25%, .75% and .75% of the Fund's av-
 erage daily net assets attributable to Class A, Class B and Class C shares,
 respectively. For the year ended October 31, 1998, Goldman Sachs had volun-
 tarily agreed to waive approximately $882,000 of its distribution fee attrib-
 utable to Class A shares.
   The Trust, on behalf of the Fund, had also adopted Authorized Dealer Serv-
 ice Plans (the "Dealer Service Plans") pursuant to which Goldman Sachs and
 Authorized Dealers were compensated for providing personal and account main-
 tenance services. The Fund paid a fee under its Dealer Service Plans equal,
 on an annual basis, up to .25% of the average daily net assets attributable
 to the Class A, Class B and Class C shares.
   Effective October 1, 1998, the Distribution Plans and Dealer Service Plans
 were combined into Distribution and Service Plans. Under the Distribution and
 Service Plans, Goldman Sachs and or Authorized Dealers are entitled to a
 monthly fee for distribution and shareholder maintenance services equal, on
 an annual basis, to .25%, 1.00% and 1.00% of the average daily net assets at-
 tributable to Class A, Class B and Class C shares, respectively.
   Goldman Sachs also serves as the Transfer Agent of the Fund for a fee. Ef-
 fective October 1, 1998, fees charged for such transfer agency services are
 calculated daily and payable monthly at an annual rate as follows: .19% of
 average daily net assets for Class A, Class B and Class C shares and .04% of
 average daily net assets for Institutional and Service Class shares.
   The Trust, on behalf of the Fund, has adopted a Service Plan. This plan al-
 lows for Service shares to compensate service organizations for providing va-
 rying levels of account administration and shareholder liaison services to
 their customers who are beneficial owners of such shares. The Service Plan
 provides for compensation to the service organizations in an amount up to
 .50% (on a annualized basis), of the average daily net asset value of the
 Service shares.
   At October 31, 1998, the Fund owed approximately $293,000, $112,000 and
 $84,000 for Management, Distribution and Service and Transfer Agent Fees, re-
 spectively.
 
 4. PORTFOLIO SECURITIES TRANSACTIONS
 
 Purchase and proceeds of sales or maturities of long-term securities for the
 year ended October 31, 1998, were $680,062,284 and $475,784,159, respective-

Notes to Financial Statements
October 31, 1998
 
   The contractual amounts of forward foreign currency exchange contracts do
 not necessarily represent the amounts potentially subject to risk. The mea-
 surement of the risks associated with these instruments is meaningful only
 when all related and offsetting transactions are considered. At October 31,
 1998, the Fund had sufficient cash and/or securities to cover any commitments
 under these contracts.
   The Fund has recorded a "Receivable for forward foreign currency exchange
 contracts" and "Payable for forward foreign currency exchange contracts" re-
 sulting from open forward foreign currency exchange contracts of $95,694 and
 $2,677,953, respectively, in the accompanying Statement of Assets and Liabil-
 ities.
 
 5. REPURCHASE AGREEMENTS
 
 During the term of a repurchase agreement, the value of the underlying secu-
 rities, including accrued interest, is required to equal or exceed the value
 of the repurchase agreement. The underlying securities for all repurchase
 agreements are held in safekeeping at the Fund's custodian.
 
 6. JOINT REPURCHASE AGREEMENT ACCOUNT
 
 The Fund, together with other registered investment companies having manage-
 ment agreements with GSAM, transfers uninvested cash into joint accounts, the
 daily aggregate balance of which is invested in one or more repurchase agree-
 ments. At October 31, 1998, the Fund had an undivided interest in the repur-
 chase agreement in the following joint account which equaled $45,200,000 in
 principal amount. At October 31, 1998, the following repurchase agreements
 held in this joint account were fully collateralized by U.S. Treasury and
 agency obligations.

 8. LINE OF CREDIT FACILITY
 
 The Fund participates in a $250,000,000 uncommitted, unsecured revolving line
 of credit facility. In addition, the Fund participates in a $50,000,000 com-
 mitted, unsecured revolving line of credit facility. Both facilities are to
 be used solely for temporary or emergency purposes. Under the most restric-
 tive arrangement, the Fund must own securities having a market value in ex-
 cess of 300% of the total bank borrowings. The interest rate on borrowings is
 based on the federal funds rate. The committed facility also requires a fee
 to be paid by the Fund based on the amount of the commitment which has not
 been utilized. For the year ended October 31, 1998, the Fund did not have any
 borrowings under these facilities.
 
 9. CERTAIN RECLASSIFICATIONS
 
 In accordance with Statement of Position 93-2, the Fund has reclassified
 $711,605 from accumulated undistributed net investment income to accumulated
 net realized loss. In addition, the Fund has reclassified $152,089 and
 $183,126 from accumulated net realized loss to paid-in capital and accumu-
 lated undistributed net investment income, respectively. These reclassifica-
 tions have no impact on the net asset value of the Funds and are designed to
 present the Fund's capital accounts on a tax basis.

Report of Independent Public Accountants
 
 To the Shareholders and Board of Trustees of Goldman Sachs Trust -- High
 Yield Fund:
 
 We have audited the accompanying statement of assets and liabilities of the
 Goldman Sachs High Yield Fund, one of the portfolios constituting Goldman
 Sachs Trust -- Fixed Income Funds (a Delaware Business Trust), including the
 statement of investments, as of October 31, 1998, and the related statement
 of operations and the statements of changes in net assets and the financial
 highlights for the periods presented. These financial statements and the fi-
 nancial highlights are the responsibility of the Fund's management. Our re-
 sponsibility is to express an opinion on these financial statements and the
 financial highlights based on our audit.
 
 We conducted our audit in accordance with generally accepted auditing stan-
 dards. Those standards require that we plan and perform the audit to obtain
 reasonable assurance about whether the financial statements and the financial
 highlights are free of material misstatement. An audit includes examining, on
 a test basis, evidence supporting the amounts and disclosures in the finan-
 cial statements. Our procedures included confirmation of securities owned as
 of October 31, 1998 by correspondence with the custodian and brokers. An au-
 dit also includes assessing the accounting principles used and significant
 estimates made by management, as well as evaluating the overall financial
 statement presentation. We believe that our audit provides a reasonable basis
 for our opinion.
 
 In our opinion, the financial statements and the financial highlights re-
 ferred to above present fairly, in all material respects, the financial posi-
 tion of Goldman Sachs High Yield Fund as of October 31, 1998, the results of
 its operations and the changes in its net assets and the financial highlights
 for the periods presented, in conformity with generally accepted accounting

Notes to Financial Statements
October 31, 1998
 1. ORGANIZATION
 
 Goldman Sachs Trust (the "Trust") is a Delaware business trust registered un-
 der the Investment Company Act of 1940 (as amended) as an open-end, manage-
 ment investment company. The Trust includes the Goldman Sachs Short Duration
 Tax-Free Fund (Short Duration Tax-Free) and the Goldman Sachs Municipal In-
 come Fund (Municipal Income), collectively, "the Funds" or individually a
 "Fund." Short Duration Tax-Free is a diversified portfolio offering six clas-
 ses of shares -- Class A, Class B, Class C, Institutional, Administration,
 and Service. Municipal Income, also a diversified portfolio, offers five
 classes of shares -- Class A, Class B, Class C, Institutional and Service.
 
 2. SIGNIFICANT ACCOUNTING POLICIES
 
 The following is a summary of significant accounting policies consistently
 followed by the Funds. The preparation of financial statements in conformity
 with generally accepted accounting principles requires management to make es-
 timates and assumptions that may affect the reported amounts.
 
 A. Investment Valuation -- Portfolio securities for which accurate market
 quotations are readily available are valued on the basis of quotations fur-
 nished by a pricing service or provided by dealers in such securities. Port-
 folio securities for which accurate market quotations are not readily
 available are valued based on yield equivalents, pricing matrices or other
 sources, under valuation procedures established by the Trust's Board of
 Trustees. Short-term debt obligations maturing in sixty days or less are val-
 ued at amortized cost.
 
 B. Security Transactions and Investment Income -- Security transactions are
 recorded on the trade date. Realized gains and losses on sales of portfolio
 securities are calculated using the identified cost basis. Interest income is
 recorded on the basis of interest accrued. Market premiums resulting from the
 purchase of long-term debt securities are amortized to interest income over
 the life of the security with a corresponding decrease in the cost basis of
 the security.
 
 C. Federal Taxes -- It is each Fund's policy to comply with the requirements
 of the Internal Revenue Code applicable to regulated investment companies and
 to distribute each year substantially all of its investment company tax-ex-
 empt and taxable income and capital gains to its shareholders. Accordingly,
 no federal tax provisions are required.
   The characterization of distributions to shareholders for financial report-
 ing purposes is determined in accordance with income tax rules. Therefore,
 the source of a portfolio's distributions may be shown in the accompanying
 financial statements as either from or in excess of net investment income or
 net realized gain on investment transactions, or from paid-in capital, de-
 pending on the type of book/tax differences that may exist as well as timing
 differences associated with having different book and tax year ends.
   The Short Duration Tax-Free Fund, at its most recent tax year-end of Decem-
 ber 31, 1997 had approximately the following amount of capital loss
 carryforwards for U.S. federal tax purposes. This amount is available to be
 carried forward to offset future capital gains to the extent permitted by ap-
 plicable laws or regulations.

GOLDMAN SACHS TAX-FREE FUNDS
Notes to Financial Statements (continued)
October 31, 1998
 D. Expenses -- Expenses incurred by the Trust that do not specifically relate
 to an individual Fund of the Trust are allocated to the Funds based on the
 nature of the expense.
   Class A, Class B and Class C shareholders of the Funds bear all expenses
 and fees relating to their respective distribution and service plans. Share-
 holders of Service and Administration shares bear all expenses and fees paid
 to service organizations for their services with respect to such shares. Ef-
 fective October 1, 1998, each class of shares of the Funds now separately
 bears its respective class-specific transfer agency fees.
 
 E. Deferred Organization Expenses -- Organization-related costs were amor-
 tized on a straight-line basis over a period of five years. The Short Dura-
 tion Tax-Free and Municipal Income Fund's organizational costs are fully
 amortized.
 
 F. Futures Contracts -- The Funds may enter into futures transactions in or-
 der to hedge against changes in interest rates, securities prices or to seek
 to increase total return.
   Upon entering into a futures contract, the Funds are required to deposit
 with a broker an amount of cash or securities equal to the minimum "initial
 margin" requirement of the associated futures exchange. Subsequent payments
 for futures contracts ("variation margin") are paid or received by the Funds
 daily, dependent on the daily fluctuations in the value of the contracts, and
 are recorded for financial reporting purposes as unrealized gains or losses.
 When contracts are closed, the Funds realize a gain or loss which is reported
 in the Statements of Operations.
   The use of futures contracts involve, to varying degrees, elements of mar-
 ket and counterparty risk which may exceed the amounts recognized in the
 Statements of Assets and Liabilities. Changes in the value of the futures
 contract may not directly correlate with changes in the value of the under-
 lying securities. This risk may decrease the effectiveness of the Funds'
 hedging strategies and potentially result in a loss.
 
 G. Option Accounting Principles -- When the Funds write call or put options,
 an amount equal to the premium received is recorded as an asset and as an
 equivalent liability. The amount of the liability is subsequently marked-to-
 market to reflect the current market value of the option written. When a
 written option expires on its stipulated expiration date or the Funds enter
 into a closing purchase transaction, the Funds realize a gain or loss without
 regard to any unrealized gain or loss on the underlying security, and the li-
 ability related to such option is extinguished. When a written call option is
 exercised, the Funds realize a gain or loss from the sale of the underlying
 security, and the proceeds of the sale are increased by the premium origi-
 nally received. When a written put option is exercised, the amount of the
 premium originally received will reduce the cost of the security which the
 Funds purchase upon exercise. There is a risk of loss from a change in value
 of such options which may exceed the related premiums received.
   Upon the purchase of a call option or a protective put option by the Funds,
 the premium paid is recorded as an investment and subsequently marked-to-mar-
 ket to reflect the current market value of the option. If an option which the
 Funds have purchased expires on the stipulated expiration date, the Funds
 will realize a loss in the amount of the cost of the option. If the Funds en-
 ter into a closing sale transaction, the Funds will realize a gain or loss,
 depending on whether the sale proceeds for the closing sale transaction are
 greater or less than the cost of the option. If the Funds exercise a pur-
 chased put option, the Funds will realize a gain or loss from the sale of the
 underlying security, and the proceeds from such sale will be decreased by the
 premium originally paid. If the Funds exercise a purchased call option, the
 cost of the security which the Funds purchase upon exercise will be increased
 by the premium originally paid.

 3. AGREEMENTS
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as each Fund's investment ad-
 viser pursuant to Investment Management Agreements (the "Agreements"). Under
 the Agreements, GSAM, subject to the general supervision of the Trust's Board
 of Trustees, manages the Funds' portfolios. As compensation for the services
 rendered pursuant to the Agreements and the assumption of the expenses re-
 lated thereto and administering the Funds' business affairs, including pro-
 viding facilities, GSAM is entitled to a fee, computed daily and payable
 monthly at an annual rate equal to .40% and .55% of average daily net assets
 of Short Duration Tax-Free and Municipal Income, respectively. GSAM has vol-
 untarily agreed to waive a portion of its management fee for each Fund. For
 the period ended October 31, 1998, GSAM waived approximately $3,000 and
 $4,000 of its management fee attributable to the Short Duration Tax-Free and
 Municipal Income Funds, respectively. GSAM may discontinue or modify these
 waivers in the future at its discretion.
   GSAM voluntarily agreed to limit "Other Expenses" (excluding management,
 distribution and service fees, Administration and Service share fees, taxes,
 interest, brokerage, litigation, indemnification costs and other extraordi-
 nary expenses) through September 30, 1998 to the extent such expenses ex-
 ceeded .05% of the average daily net assets of each Fund. Effective October
 1, 1998, the expense limitations were modified until further notice to .00%
 of the average daily net assets of each Fund. For the year ended October 31,
 1998, Goldman Sachs reimbursed approximately $402,000 and $509,000 to Short
 Duration Tax-Free and Municipal Income, respectively. At October 31, 1998 ap-
 proximately $103,000 and $122,000 was owed to Short Duration Tax-Free and Mu-
 nicipal Income, respectively.
   Goldman Sachs serves as the Distributor of shares of the Funds pursuant to
 a Distribution Agreement. Goldman Sachs may receive a portion of the Class A
 sales load and Class B and Class C contingent deferred sales charges and has
 advised the Funds that it retained approximately $55,000 and $126,000 for the
 year ended October 31, 1998 for Short Duration Tax-Free and Municipal Income,
 respectively.
   The Trust, on behalf of each Fund, had adopted Distribution Plans (the
 "Distribution Plans") pursuant to Rule 12b-1. Under the Distribution Plans,
 Goldman Sachs was entitled to a quarterly fee from each Fund for distribution
 services equal, on an annual basis, to .25%, .75% and .75% of each Fund's
 average daily net assets attributable to Class A, Class B and Class C shares,
 respectively. For the year ended October 31, 1998, the Distributor had
 voluntarily agreed to waive approximately $25,000 and $179,000 of its
 distribution fee attributable to Class A shares of Short Duration Tax-Free
 and Municipal Income, respectively.
   The Trust, on behalf of each Fund, had also adopted Authorized Dealer Serv-
 ice Plans (the "Dealer Service Plans") pursuant to which Goldman Sachs and
 Authorized Dealers were compensated for providing personal and account main-
 tenance services. Each Fund paid a fee under its Dealer Service Plan equal,
 on an annual basis, up to .25% of the average daily net assets attributable
 to the Class A, Class B and Class C shares.
   Effective October 1, 1998, the Distribution Plans and Dealer Service Plans
 were combined into Distribution and Service Plans. Under the Distribution and
 Service Plans, Goldman Sachs and/or Authorized Dealers are entitled to a
 monthly fee from each fund for distribution and shareholder maintenance serv-
 ices equal, on an annual basis, to .25%, 1.00% and 1.00% of the average daily
 net assets attributable to Class A, Class B and Class C shares, respectively.
 For the year ended October 31, 1998, Goldman Sachs has voluntarily agreed to
 waive approximately $1,000 of the combined prior 12b-1 Distribution fees and
 Distribution and Service fees attributable to the Class B shares of Short Du-
 ration Tax-Free. Goldman Sachs may discontinue or modify this waiver in the
 future at its discretion.
 
                                                                              23

October 31, 1998
   Goldman Sachs also serves as the Transfer Agent of the Funds for a fee. Ef-
 fective October 1, 1998, fees charged for such transfer agency services are
 calculated daily and payable monthly at an annual rate as follows: .19% of
 average daily net assets for Class A, Class B and Class C Shares and .04% of
 average daily net assets for Institutional, Service and Administration
 Shares.
   The Trust, on behalf of the Funds, has adopted Service Plans. In addition,
 the Trust, on behalf of Short Duration Tax-Free, has adopted an Administra-
 tion Plan. These plans allow for Service shares and Administration shares,
 respectively, to compensate service organizations for providing varying lev-
 els of account administration and shareholder liaison services to their cus-
 tomers who are beneficial owners of such shares. The Service and
 Administration Plans provide for compensation to the service organizations in
 an amount up to .50% and .25% (on an annualized basis), respectively, of the
 average daily net asset value of the respective shares.
   At October 31, 1998, the amounts owed to affiliates were as follows (in
 thousands):

 5. LINE OF CREDIT FACILITY
 
 The Funds participate in a $250,000,000 uncommitted, unsecured revolving line
 of credit facility to be used solely for temporary or emergency purposes. Un-
 der the most restrictive arrangement, each Fund must own securities having a
 market value in excess of 300% of the total bank borrowings. The interest
 rate on borrowings is based on the federal funds rate. For the year ended Oc-
 tober 31, 1998, the Funds did not have any borrowings under this facility.
 
 6. CERTAIN RECLASSIFICATIONS
 
 In accordance with Statement of Position 93-2, Short Duration Tax-Free has
 reclassified $6,349 and $229 from paid-in capital to accumulated undistrib-
 uted net investment income and accumulated net realized loss, respectively.
 Municipal Income Fund has reclassified $82 and $114 from paid-in capital and
 undistributed net investment income, respectively, to accumulated net real-
 ized gain. These reclassifications have no impact on the net asset value of
 the Funds and are designed to present the Fund's capital accounts on a tax
 basis.

GOLDMAN SACHS TRUST - TAX-FREE FUNDS
Report of Independent Public Accountants
 To the Shareholders and Board of Trustees of Goldman Sachs Trust -- Tax-Free
 Fixed Income Funds:
 
 We have audited the accompanying statement of assets and liabilities of
 Goldman Sachs Short Duration Tax-Free Fund and Municipal Income Fund, two of
 the portfolios constituting Goldman Sachs Trust -- Fixed Income Funds (a Del-
 aware Business Trust), including the statement of investments, as of October
 31, 1998, and the related statements of operations and the statements of
 changes in net assets and the financial highlights for the periods presented.
 These financial statements and the financial highlights are the responsibil-
 ity of the Funds' management. Our responsibility is to express an opinion on
 these financial statements and the financial highlights based on our audits.
 
 We conducted our audits in accordance with generally accepted auditing
 standards. Those standards require that we plan and perform the audit to
 obtain reasonable assurance about whether the financial statements and the
 financial highlights are free of material misstatement. An audit includes
 examining, on a test basis, evidence supporting the amounts and disclosures
 in the financial statements. Our procedures included confirmation of
 securities owned as of October 31, 1998 by correspondence with the custodian
 and brokers. An audit also includes assessing the accounting principles used
 and significant estimates made by management, as well as evaluating the
 overall financial statement presentation. We believe that our audits provide
 a reasonable basis for our opinion.
 
 In our opinion, the financial statements and the financial highlights
 referred to above present fairly, in all material respects, the financial
 position of Goldman Sachs Short Duration Tax-Free Fund and Municipal Income
 Fund as of October 31, 1998, the results of their operations and the changes
 in their net assets and the financial highlights for the periods presented,
 in conformity with generally accepted accounting principles.
