WHAT ARE THE RISK FACTORS AND SPECIAL CHARACTERISTICS THAT I SHOULD CONSIDER
BEFORE INVESTING?

         Each Fund's share price will fluctuate with market, economic and, to
the extent applicable, foreign exchange conditions, so that an investment in any
of the Funds may be worth more or less when redeemed than when purchased. None
of the Funds should be relied upon as a complete investment program. There can
be no assurance that a Fund's investment objectives will be achieved. See "Risk
Factors."

         RISKS OF INVESTING IN SMALL CAPITALIZATION COMPANIES. To the extent
that a Fund invests in the securities of small market capitalization companies,
the Fund may be exposed to a higher degree of risk and price volatility.
Securities of such issuers may lack sufficient market liquidity to enable a Fund
to effect sales at an advantageous time or without a substantial drop in price.

         FOREIGN RISKS. Investments in securities of foreign issuers and
currencies involve risks that are different from those associated with
investments in domestic securities. The risks associated with foreign
investments and currencies include changes in relative currency exchange rates,
political and economic developments, the imposition of exchange controls,
confiscation and other governmental restrictions. Generally, there is less
availability of data on foreign companies and securities markets as well as less
regulation of foreign stock exchanges, brokers and issuers. A Fund's investments
in emerging markets and countries ("Emerging Countries") involve greater risks
than investments in the developed countries of Western Europe, the United
States, Canada, Australia, New Zealand and Japan. In addition, because the
International Equity and Global Income Funds invest primarily outside the United
States, these Funds may involve greater risks, since the securities markets of
foreign countries are generally less liquid and subject to greater price
volatility. The securities markets of emerging countries, including those in
Asia, Latin America, Eastern Europe and Africa are marked by a high
concentration of market capitalization and trading volume in a small number of
issuers representing a limited number of industries, as well as a high
concentration of ownership of such securities by a limited number of investors.

         To the extent that a Fund invests in fixed income securities, it will
be susceptible to the following risks:

         INTEREST RATE RISK. When interest rates decline, the market value of
fixed-income securities tends to increase. Conversely, when interest rates
increase, the market 

                                      -7-
<PAGE>
 
value of fixed-income securities tends to decline. Volatility of a security's
market value will differ depending upon the security's duration, the issuer and
the type of instrument.

         DEFAULT RISK/CREDIT RISK. Investments in fixed-income securities are
subject to the risk that the issuer could default on its obligations and a Fund
could sustain losses on such investments. A default could impact both interest
and principal payments.


         CALL RISK AND EXTENSION RISK. Fixed-income securities may be subject to
both call risk and extension risk. Call risk (i.e., where the issuer exercises
its rights to pay principal on an obligation earlier than scheduled) causes cash
flow to be returned earlier than expected. This typically results when interest
rates have declined, and a Fund may be unable to recoup all of its initial
investments and will also suffer from having to reinvest in lower yielding
securities. Extension risk (i.e., where the issuer exercises its right to pay
principal on an obligation later than scheduled) causes cash flows to be
returned later than expected. This typically results when interest rates have
increased and a Fund will suffer from the inability to invest in higher yielding
securities. The investment characteristics of mortgage-backed securities
(including adjustable rate mortgage securities) and asset-backed securities
differ from those of traditional fixed-income securities because they generally
have both call risk (also known as prepayment risk) and extension risk.

         RISKS OF INVESTING IN NON-INVESTMENT GRADE FIXED-INCOME SECURITIES.
Non-investment grade fixed-income securities (commonly referred to as "junk
bonds") are subject to greater volatility and risk of loss and are less liquid
than securities which are perceived to be of higher credit quality. Such
securities, also referred to as high yield securities, are considered to be
speculative by traditional investment standards. High yield securities are
subject to increased risk of an issuer's inability to meet principal and
interest payments. The High Yield Fund may invest in securities which are in
default at the time of investment. The market for non-investment grade
securities tends to be concentrated in a limited number of market makers, which
may affect liquidity. In addition, the market price of such securities tends to
reflect individual corporate developments to a greater extent than that of
higher rated securities which react primarily to the general level of interest
rates.

         NON-DIVERSIFIED. Global Income Fund is a "non-diversified" fund as
defined under the Investment Company Act of 1940, as amended (the "Act"), and
is, therefore, subject only to certain federal tax diversification requirements
(to which the other Funds are also subject), in addition to the policies adopted
by the Investment Adviser. To the extent that the Fund is not diversified under
the Act, it will be more susceptible to adverse 

                                      -8-
<PAGE>
 
developments affecting any single issuer of portfolio securities. See
"Investment Restrictions."

         OTHER. A Fund's use of certain investment techniques, including
derivatives, forward contracts, options, futures, and swap transactions will
subject the Fund to greater risk than funds that do not employ such techniques.

WHO MANAGES THE FUNDS?

         GSAM serves as Investment Adviser to the Growth and Income, CORE U.S.
Equity, CORE Large Cap Growth, Capital Growth, CORE Small Cap Equity, Mid Cap
Equity and High Yield Funds. GSAMI serves as Investment Adviser to the
International Equity and Global Income Funds. As of October 24, 1997, the
Investment Advisers, together with their affiliates, acted as investment adviser
for assets in excess of $128 billion.

WHO DISTRIBUTES THE FUNDS' SHARES?

         Goldman Sachs acts as distributor of each Fund's shares.

HOW DO I PURCHASE OR REDEEM SHARES?

         Investors may purchase or redeem shares of the Funds in connection with
variable annuity contracts and variable life insurance policies offered through
the Separate Accounts of Participating Insurance Companies. You should refer to
the prospectus of your Participating Insurance Company's Separate Account for
information on how to purchase a variable annuity contract or variable life
insurance policy, how to select specific Funds as investment options for your
contract or policy and how to redeem monies from the Trust. See "Purchase and
Redemption of Shares."

WHEN ARE DIVIDENDS AND DISTRIBUTIONS PAID?


         Investment income dividends and capital gains distributions are paid at
least annually.

         All dividends and capital gain distributions will be automatically
reinvested in additional shares of a Fund at the 

                                      -9-
<PAGE>
 
net asset value of such shares on the payment date, unless a Separate Account is
permitted to hold cash and elects to receive payment in cash. For further
information concerning dividends, see "Dividends."

                         OVERVIEW OF INVESTMENT STYLES

EQUITY FUNDS - GROWTH AND INCOME, CORE U.S. EQUITY, CORE LARGE CAP GROWTH, CORE
SMALL CAP EQUITY, CAPITAL GROWTH, MID CAP EQUITY AND INTERNATIONAL EQUITY FUNDS

         The Investment Advisers may purchase for these Equity Funds common
stocks, preferred stocks, interests in real estate investment trusts,
convertible debt obligations, convertible preferred stocks, equity interests in
trusts, partnerships, joint ventures, limited liability companies and similar
enterprises, warrants and stock purchase rights ("equity securities"). In
choosing a Fund's securities, the Investment Advisers utilize first-hand
fundamental research, including visiting company facilities to assess operations
and to meet decision-makers. The Investment Advisers may also use macro analysis
of numerous economic and valuation variables to anticipate changes in company
earnings and the overall investment climate. Except as discussed in "Activities
of Goldman Sachs and its Affiliates and Other Accounts Managed by Goldman
Sachs," the Investment Advisers are able to draw on the research and market
expertise of the Goldman Sachs Global Investment Research Department and other
affiliates of the Investment Advisers, as well as information provided by other
securities dealers. Equity securities in a Fund's portfolio will generally be
sold when the Investment Adviser believes that the market price fully reflects
or exceeds the securities' fundamental valuation or when other more attractive
investments are identified.

         VALUE STYLE. The Growth and Income and Mid Cap Equity Funds are managed
using a value-oriented approach. The Investment Adviser evaluates securities
using fundamental analysis and intends to purchase equity securities that are,
in its view, underpriced relative to a combination of such companies' long-term
earnings prospects, growth rate, free cash flow and/or dividend-paying ability.

         Consideration will be given to the business quality of the issuer.
Factors positively affecting the Investment Adviser's view of that quality
include the competitiveness and degree of regulation in the markets in which the
company operates, the existence of a management team with a record of success,
the position of the company in the markets in which it operates, the level of
the company's financial leverage and the sustainable return on capital invested
in the business. The Funds may also purchase securities of companies that have
experienced 

                                      -10-
<PAGE>
 
difficulties and that, in the opinion of the Investment Adviser, are available
at attractive prices.

         GROWTH STYLE. The Capital Growth and International Equity Funds are
managed using a growth oriented approach. Equity securities for these Funds are
selected based on their prospects for above average growth. The Investment
Adviser will select securities of growth companies trading, in the Investment
Adviser's opinion, at a reasonable price relative to other industries,
competitors and historical price/earnings multiples. These Funds will generally
invest in companies whose earnings are believed to be in a relatively strong
growth trend, or, to a lesser extent, in companies in which significant further
growth is not anticipated but whose market value per share is thought to be
undervalued. In order to determine whether a security has favorable growth
prospects, the Investment Adviser ordinarily looks for one or more of the
following characteristics in relation to the security's prevailing price:
prospects for above average sales and earnings growth per share; high return on
invested capital; free cash flow generation; sound balance sheet, financial and
accounting policies, and overall financial strength; strong competitive
advantages; effective research, product development, and marketing; pricing
flexibility; strength of management; and general operating characteristics that
will enable the company to compete successfully in its marketplace.

         QUANTITATIVE STYLE. The CORE U.S. Equity, CORE Large Cap Growth and
CORE Small Cap Equity Funds (the "CORE Funds") are managed using both
quantitative and fundamental techniques. CORE is an acronym for
"Computer-Optimized, Research-Enhanced," which reflects the Funds' investment
process. This investment process and the proprietary multifactor model used to
implement it are discussed below.

         CORE Investment Process. The Investment Adviser begins with a broad
         -----------------------
universe of U.S. equity securities for the CORE Funds. The Investment Adviser
uses a proprietary multifactor model (the "Multifactor Model") to assign each
equity security a rating. In the case of a security followed by the Goldman
Sachs Global Investment Research Department (the "Research Department"), a
second rating is assigned based upon the Research Department's evaluation. In
the discretion of the Investment Adviser, such ratings may also be assigned to
securities based on research ratings obtained from other industry sources.

         In building a diversified portfolio for each CORE Fund, the Investment
Adviser utilizes optimization techniques to seek to maximize the Fund's expected
return, while maintaining a risk profile similar to the Fund's benchmark. Each
portfolio is primarily comprised of securities rated highest by the foregoing
investment process and has risk characteristics and industry weightings similar
to the relevant Fund's benchmark.

                                      -11-
<PAGE>
 
         Multifactor Model. The Multifactor Model is a rigorous computerized
         -----------------
rating system for forecasting the returns of individual equity securities
according to fundamental investment characteristics. The Multifactor Model
incorporates common variables covering measures of value, growth, momentum and
risk (e.g., book/price ratio, earnings/price ratio, price momentum, price
volatility, consensus growth forecasts, earnings estimate revisions and earnings
stability). All of the factors used in the Multifactor Model have been shown to
significantly impact the performance of the securities and markets they were
designed to forecast.

         The weightings assigned to the factors in the Multifactor Model used by
the CORE Funds are derived using a statistical formulation that considers each
factor's historical performance in different market environments. As such, the
Multifactor Model is designed to evaluate each security using only the factors
that are statistically related to returns in the anticipated market environment.
Because it includes many disparate factors, the Investment Adviser believes that
the Multifactor Model is broader in scope and provides a more thorough
evaluation than most conventional, quantitative models. Securities and markets
ranked highest by the Multifactor Model do not have one dominant investment
characteristic; rather, they possess an attractive combination of investment
characteristics.

         Research Department. In assigning ratings to equity securities, the
         -------------------
Research Department uses a four category rating system ranging from "recommended
for purchase" to "likely to underperform." The ratings reflect the analyst's
judgment as to the investment results of a specific security and incorporate
economic outlook, valuation, risk and a variety of other factors.

         By employing both a quantitative (i.e., the Multifactor Model) and a
qualitative (i.e., research enhanced) method of selecting securities, each CORE
Fund seeks to capitalize on the strengths of each discipline.

FIXED-INCOME FUNDS - GLOBAL INCOME AND HIGH YIELD FUNDS

         The Investment Adviser of the Global Income and High Yield Funds may in
accordance with the respective Funds' investment objectives and policies,
purchase all types of fixed income securities, including U.S. and foreign
government securities, and senior and subordinated corporate debt obligations
such as bonds, debentures, notes and commercial paper.

         As stated above, each of these two Funds 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 

                                      -12-
<PAGE>
 
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 otherwise noted.

         A Fund will deem a security to have met its minimum credit rating
requirement if the security receives the minimum required long-term rating (or
the equivalent short-term credit rating) at the time of purchase from at least
one rating organization (including, but not limited to, Standard & Poor's
Ratings Group ("S&P") and Moody's Investors Service, Inc. ("Moody's")) even
though it has been rated below the minimum rating by one or more other rating
organizations, or, if unrated by a rating organization, is determined by the
Investment Adviser to be of comparable quality. If a security satisfies a Fund's
minimum rating criteria 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 interest of a Fund and its
shareholders.

         Except as discussed in "Activities of Goldman Sachs and its Affiliates
and Other Accounts Managed by Goldman Sachs," the Investment Adviser will 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.

                      INVESTMENT OBJECTIVES AND POLICIES

         The investment objectives and principal investment policies of each
Fund are described below. Other investment practices and management techniques,
which involve certain risks, are described under "Description of Securities,"
"Risk Factors" and "Investment Techniques." There can be no assurance that a
Fund's investment objectives will be achieved.

GROWTH AND INCOME FUND

         Objectives. The Fund's investment objectives are to provide investors
         ----------
with long-term growth of capital and growth of income.

         Primary Investment Focus. The Fund invests, under normal circumstances,
         ------------------------
at least 65% of its total assets in equity securities that the Investment
Adviser considers to have favorable prospects for capital appreciation and/or
dividend-paying ability.

                                      -13-
<PAGE>
 
         Other. The Fund may invest up to 35% of its total assets in fixed
         -----
income securities that, in the opinion of the Investment Adviser, offer the
potential to further the Fund's investment objectives. In addition, although the
Fund will invest primarily in publicly traded U.S. securities, it may invest up
to 25% of its total assets in foreign securities, including securities of
issuers in Emerging Countries and securities quoted in foreign currencies.

CORE U.S. EQUITY FUND

         Objective. The Fund's investment objective is to provide investors with
         ---------
long-term growth of capital and dividend income. The Fund seeks to achieve its
objective through a broadly diversified portfolio of large cap and blue chip
equity securities representing all major sectors of the U.S. economy.

         Primary Investment Focus. The Fund invests, under normal circumstances,
         ------------------------
at least 90% of its total assets in equity securities of U.S. issuers. The Fund
may invest in equity securities of foreign issuers that are traded in the United
States and that comply with U.S. accounting standards. The Fund's investments
are selected using both a variety of quantitative techniques and fundamental
research in seeking to maximize the Fund's expected return, while maintaining
risk, style, capitalization and industry characteristics similar to the S&P 500
Index. The Fund seeks a broad representation in most major sectors of the U.S.
economy and a portfolio comprised of companies with average long-term earnings
growth expectations and dividend yields. The Fund may invest only in fixed
income securities that are considered cash equivalents.

         For a description of the investment process of the Fund, see "Overview
of Investment Styles."

CORE LARGE CAP GROWTH FUND

         Objective. The Fund's investment objective is to provide investors with
         ---------
long-term growth of capital. The Fund seeks to achieve its objective through a
broadly diversified portfolio of equity securities of large cap U.S. issuers
that are expected to have better prospects for earnings growth than the growth
rate of the general domestic economy. Dividend income is a secondary
consideration.

         Primary Investment Focus. The Fund invests, under normal circumstances,
         ------------------------
at least 90% of its total assets in equity securities of U.S. issuers, including
foreign issuers that are traded in the United States and that comply with U.S.
accounting standards. The Investment Adviser emphasizes a company's growth
prospects in analyzing equity securities to be purchased by the Fund. The Fund's
investments are selected using both a variety of quantitative techniques and
fundamental research in seeking to 

                                      -14-
<PAGE>
 
maximize the Fund's expected return, while maintaining risk, style,
capitalization and industry characteristics similar to the Russell 1000 Growth
Index. The Fund seeks a portfolio comprised of companies with above average
capitalizations and earnings growth expectations and below average dividend
yields. The Fund may invest only in fixed income securities that are considered
cash equivalents.

         For a description of the investment process of the Fund, see "Overview
of Investment Styles."

CORE SMALL CAP EQUITY FUND

         Objective. The Fund's investment objective is to provide investors with
         ---------
long-term growth of capital. The Fund seeks to achieve its objective through a
broadly diversified portfolio of equity securities of U.S. issuers which are
included in the Russell 2000 Index at the time of investment.

         Primary Investment Focus. The Fund invests, under normal circumstances,
         ------------------------
at least 90% of its total assets in equity securities of U.S. issuers, including
foreign issuers that are traded in the United States and that comply with U.S.
accounting standards. The Fund's investments are selected using both a variety
of quantitative techniques and fundamental research in seeking to maximize the
Fund's expected return, while maintaining risk, style, capitalization and
industry characteristics similar to the Russell 2000 Index. The Fund seeks a
portfolio comprised of companies with small market capitalizations, strong
expected earnings growth and momentum, and better valuation and risk
characteristics than the Russell 2000 Index. The Fund may invest only in fixed
income securities that are considered cash equivalents.

         The Investment Adviser believes that companies in which the Fund may
invest offer greater opportunity for growth of capital than larger, more mature
better known companies. Investments in small market capitalization issuers
involve special risks. See "Description of Securities" and "Risk Factors." If
the issuer of a portfolio security held by the Fund is no longer included in the
Russell 2000 Index, the Fund may, but is not required to, sell the security.

         For a description of the investment process of the Fund, see "Overview
of Investment Styles."

CAPITAL GROWTH FUND

         Objective. The Fund's investment objective is to provide investors with
         ---------
long-term growth of capital.

         Primary Investment Focus. The Fund invests, under normal circumstances,
         ------------------------
at least 90% of its total assets in equity 

                                      -15-
<PAGE>
 
securities. The Fund seeks to achieve its investment objective by investing in a
diversified portfolio of equity securities that are considered by the Investment
Adviser to have long-term capital appreciation potential.

         Other. Although the Fund will invest primarily in publicly traded U.S.
         -----
securities, it may invest up to 10% of its total assets in foreign securities,
including securities of issuers in Emerging Countries and securities quoted in
foreign currencies.

MID CAP EQUITY FUND

         Objective. The Fund's investment objective is to provide investors with
         ---------
long-term capital appreciation.

         Primary Investment Focus. The Fund invests, under normal circumstances,
         ------------------------
substantially all of its assets in equity securities and at least 65% of its
total assets in equity securities of Mid Cap Companies with public stock market
capitalizations (based upon shares available for trading on an unrestricted
basis) of between $500 million and $10 billion at the time of investment. If the
company's capitalization of an issuer increases above $10 billion after purchase
of such issuer's securities, the Fund may, but is not required to, sell the
securities. Dividend income, if any, is an incidental consideration.

         Other. The Fund may invest up to 35% of its total assets in fixed
         -----
income securities. In addition, although the Fund will invest primarily in
publicly traded U.S. securities, it may invest up to 25% of its total assets in
foreign securities, including securities of issuers in Emerging Countries and
securities quoted in foreign currencies.

INTERNATIONAL EQUITY FUND

         Objective. The Fund's investment objective is to provide investors with
         ---------
long-term capital appreciation.

         Primary Investment Focus. The Fund invests, under normal circumstances,
         ------------------------
substantially all, and at least 65%, of its total assets in equity securities of
companies that are organized outside the United States or whose securities are
principally traded outside the United States. The Fund may allocate its assets
among countries as determined by the Investment Adviser from time to time
provided that the Fund's assets are invested in at least three foreign
countries. The Fund expects to invest a substantial portion of its assets in the
securities of issuers located in the developed countries of Western Europe and
in Japan. However, the Fund may also invest in the securities of issuers located
in Australia, Canada, New Zealand and in Emerging Countries such as Argentina,
Botswana, Brazil, Chile, China, Colombia, the Czech Republic, Egypt, Greece,
Hong Kong, Hungary, 

                                      -16-
<PAGE>
 
India, Indonesia, Israel, Jordan, Kenya, Malaysia, Mexico, Morocco, Pakistan,
Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South
Korea, Sri Lanka, Taiwan, Thailand, Turkey, Venezuela and Zimbabwe. Many of the
countries in which the Fund may invest have emerging markets or economies which
involve certain risks, as described below under "Risk Factors-Special Risks of
Investments in Emerging Markets," which are not present in investments in more
developed countries.

         Other. The Fund may employ certain currency techniques to seek to hedge
         -----
against currency exchange rate fluctuations or to seek to increase total return.
When used to seek to enhance return, these management techniques are considered
speculative. Such currency management techniques involve risks different from
those associated with investing solely in securities of U.S. issuers quoted in
U.S. dollars. To the extent that the Fund is fully invested in foreign
securities while also maintaining currency positions, it may be exposed to
greater combined risk. The Fund's net currency positions may expose it to risks
independent of its securities positions. See "Description of Securities,"
"Investment Techniques" and "Risk Factors." Up to 35% of the Fund's total assets
may be invested in fixed income securities.

GLOBAL INCOME FUND

         Objective. The Fund's investment objective is to provide investors with
         ---------
a high total return, emphasizing current income and, to a lesser extent,
providing opportunities for capital appreciation.

         Duration. Under normal interest rate conditions, the Fund's duration is
         --------
expected to be equal to that of the Fund's benchmark, the J.P. Morgan Global
Government Bond Index (hedged), plus or minus 2.5 years. In addition, under
normal interest rate conditions, the Fund's maximum duration will not exceed 7.5
years. The approximate interest rate sensitivity of the Fund is expected to be
comparable to a six-year bond.

         Investment Sector. The Fund invests primarily in a portfolio of high
         -----------------
quality fixed-income securities of U.S. and foreign issuers and enters into
transactions in foreign currencies. Under normal market conditions, the Fund
will (i) have at least 30% of its total assets, after considering the effect of
currency positions, denominated in U.S. dollars and (ii) invest in securities of
issuers in at least three countries. The Fund may also invest up to 10% of its
total assets in issuers in countries with emerging markets and economies. The
Fund seeks 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.

                                      -17-
<PAGE>
 
         The fixed-income securities in which the Fund may invest include: (i)
U.S. Government Securities and custodial receipts therefor; (ii) securities
issued or guaranteed by a foreign government or any of its political
subdivisions, authorities, agencies, instrumentalities or by supranational
entities (i.e., international organizations designated or supported by
governmental entities to promote economic reconstruction or development, such as
the World Bank); (iii) corporate debt securities; (iv) 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; (v) commercial paper; and (vi) mortgage-backed
and asset-backed securities.

         Credit Quality. All securities purchased by the Fund will be rated, at
         --------------
the time of investment, at least BBB by S&P or Baa by Moody's. The Fund will
invest at least 50% of its total assets in securities rated, at the time of
investment, AAA by S&P or Aaa by Moody's.

         Unrated securities will be determined to be of comparable quality by 
the Investment Adviser. Fixed-income securities rated BBB or Baa are considered 
medium-grade obligations with speculations characteristics, and adverse economic
conditions or changing conditions may weaken their issuers' capacity to pay 
interest and repay prinicipal.


         Other. The Fund may employ certain active management techniques to
         -----
manage its duration and term structure, to seek to hedge its exposure to foreign
currencies and to seek to enhance returns. These techniques include, but are not
limited to, the use of financial futures contracts, option contracts (including
options on futures), forward foreign currency exchange contracts, currency
options and futures, currency, mortgage and interest rate swaps and interest
rate floors, caps and collars. Currency management techniques involve risks
different from those associated with investing solely in U.S. dollar-denominated
fixed-income securities of U.S. issuers. It is expected that the Fund will use
certain currency techniques to seek to hedge against currency exchange rate
fluctuations or to seek to increase total return. While the 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. To the extent
that the Fund is fully invested in foreign securities while also maintaining
currency positions, it may be exposed to greater combined risk. The Fund's net
currency positions may expose it to risks independent of its securities
positions. The Fund may also employ other investment techniques to seek to
enhance returns, such as lending portfolio securities and entering into mortgage
dollar rolls, repurchase agreements and other investment practices described
under "Investment Techniques."

         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.
Concentration of the Fund's investments in such issuers will subject the Fund,
to a greater extent than if investment was more limited, to the risks of adverse
securities markets, exchange rates and social, political 

                                      -18-
<PAGE>
 

or economic events which may occur in those countries. Not more than 25% of the
Fund's total assets will be invested in securities of issuers in any other
single foreign country.
HIGH YIELD FUND

         Objective. The Fund's investment objective is to provide investors with
         ---------
a high level of current income. Secondarily, the Fund may, in seeking current
income, also consider the potential for capital appreciation.

         Duration. Under normal interest rate conditions, the Fund's duration is
         --------
expected to be equal to that of the Fund's benchmark, the Lehman Brothers High
Yield Bond Index, plus or minus 2.5 years. In addition, under normal interest
rate conditions, the Fund's maximum duration will not exceed 7.5 years. The
approximate interest rate sensitivity of the Fund is expected to be comparable
to a 6-year bond.


         Investment Sector. The Fund invests, under normal circumstances, at
         -----------------
least 65% of its total assets in high yield, fixed-income securities rated, at
the time of investment, below investment grade. Non-investment grade securities
are securities rated BB or below by S&P, Ba or below by Moody's, an equivalent
rating by another rating organization, or if unrated by a rating organization,
determined by the Investment 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, debentures, notes and
commercial paper), convertible and non-convertible corporate debt obligations,
loan participations, custodial receipts, municipal securities and 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
countries with emerging markets and economies) 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. Government securities, asset-backed and mortgage-
backed securities and corporate 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. 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.

         Credit Quality. The Fund invests primarily in high yield, fixed income
         --------------
securities rated below investment grade, including securities of issuers in
default. Non-investment grade 

                                      -19-
<PAGE>
 
securities (commonly known as "junk bonds") tend to offer higher yields than
higher rated securities with similar maturities. Non-investment grade securities
are, however, considered speculative and generally involve greater price
volatility and greater risk of loss of principal and interest than higher rated
securities. See "Description of Securities." A description of the corporate bond
and preferred stock ratings is contained in Appendix B to the Additional
Statement.

         Other. The Fund may employ certain active management techniques to
         -----
manage its duration and term structure, to seek to hedge its exposure to foreign
securities and to seek to enhance returns. These techniques include, but are not
limited to, the use of financial futures contracts, option contracts (including
options on futures), forward foreign currency exchange contracts, currency
options and futures, currency, mortgage and interest rate swaps, and interest
rate floors, caps and collars. Currency management techniques involve risks
different from those associated with investing solely in U.S. dollar-denominated
fixed-income securities of U.S. issuers. It is expected that the Fund will use
certain currency techniques to seek to hedge against currency exchange rate
fluctuations or to seek to increase total return. The Fund may also employ other
investment techniques to seek to enhance returns, such as lending portfolio
securities and entering into repurchase agreements and other investment
practices described under "Investment Techniques."

                           DESCRIPTION OF SECURITIES

CONVERTIBLE SECURITIES

         Each Fund, except the Global Income Fund, may invest in convertible
securities, including debt obligations and preferred stock of the issuer
convertible at a stated exchange rate into common stock of the issuer.
Convertible securities generally offer lower interest or dividend yields than
non-convertible securities of similar quality. As with all fixed income
securities, 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, 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 tends to trade
increasingly on a yield basis, and thus may not decline in price 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. In evaluating a convertible security, the
Investment Advisers will give primary emphasis to the 

                                      -20-
<PAGE>
 
attractiveness of the underlying common stock. The convertible securities in
which the CORE Funds invest are not subject to any minimum rating criteria. The
convertible debt securities in which the other Funds may invest are subject to
the same rating criteria as a Fund's investments in non-convertible debt
securities. Except for the High Yield Fund, convertible debt securities are
equity investments for purposes of each Fund's investment policies.

PREFERRED STOCK, WARRANTS AND RIGHTS

         Each Fund, except the Global Income 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.

REAL ESTATE INVESTMENT TRUSTS ("REITS")

         Each Fund, except the Global Income and High Yield Funds, may invest in
REITs, which are pooled investment vehicles that invest primarily in either real
estate or real estate related loans. The value of a REIT is affected by changes
in the value of the properties owned by the REIT or securing mortgage loans held
by the REIT. REITs are dependant upon cash flow from their investments to repay
financing costs and the ability of the REITs' manager. REITs are also subject to
risks generally associated with investments in real estate. A Fund will
indirectly bear its proportionate share of any expenses, including management
fees, paid by a REIT in which it invests.

                                      -21-

FOREIGN INVESTMENTS

         Foreign Securities. Each Equity Fund may invest in the securities of
         ------------------
foreign issuers (provided that the CORE Funds may only invest in equity
securities of foreign issuers that are traded in the U.S. and comply with U.S.
accounting standards). The Global Income Fund will, and the High Yield Fund may,
invest in fixed-income securities of foreign issuers denominated in any
currency. However, the High Yield Fund will limit its investments in non-U.S.
dollar-denominated fixed-income securities to 25% of its total assets.
Investments in foreign securities may offer potential benefits that are not
available from investments exclusively in securities of domestic issuers.
Foreign countries may have economic policies or business cycles different from
those of the U.S. and markets for foreign securities do not necessarily move in
a manner parallel to U.S. markets.

         Investing in the securities of foreign issuers involves risks that are
not typically associated with investing in fixed income and equity securities of
domestic issuers quoted in U.S. dollars. Such investments may be affected by
changes in currency rates, changes in foreign or U.S. laws or restrictions
applicable to such investments and 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. Commissions on transactions in foreign
securities may be higher than those for similar transactions on domestic stock
markets. In addition, clearance and settlement procedures may be different in
foreign countries and, in certain markets, such procedures have been unable to
keep pace with the volume of securities transactions, 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 about 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 possibility
of nationalization, expropriation or confiscatory 

                                      -22-
<PAGE>
 
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, political or social instability or diplomatic
developments which could affect investments in those countries.

         Each Fund other than the CORE U.S. Equity, CORE Large Cap Growth and
CORE Small Cap Equity Funds may invest in an issuer domiciled in one country yet
issuing the security in the currency of another country. The Funds may also
invest in debt securities denominated in the European Currency Unit ("ECU"),
which is a "basket" consisting of specified amounts in the currencies of certain
of the twelve member states of the European Community. The specific amounts of
currencies comprising the ECU may be adjusted by the Council of Ministers of the
European Community from time to time to reflect changes in relative values of
the underlying currencies. In addition, the Funds may invest in securities
denominated in other currency "baskets."

         Investments in ADRs, EDRs and GDRs. Each Fund, except the Global Income
         ----------------------------------
and High Yield Funds, may invest in foreign securities which take the form of
sponsored and unsponsored American Depository Receipts ("ADRs") and Global
Depository Receipts ("GDRs") and each Fund, other than the Global Income, High
Yield and CORE Funds, may also invest in European Depository Receipts ("EDRs")
or other similar instruments representing securities of foreign issuers
(together, "Depository Receipts"). ADRs represent the right to receive
securities of foreign issuers deposited in a domestic bank or a correspondent
bank. Prices of ADRs are quoted in U.S. dollars, and ADRs are traded in the
United States on exchanges or over-the-counter and are sponsored and issued by
domestic banks. EDRs and GDRs are receipts evidencing an arrangement with a
non-U.S. bank. EDRs and GDRs are not necessarily quoted in the same currency as
the underlying security. To the extent a Fund acquires Depository Receipts
through banks which do not have a contractual relationship with the foreign
issuer of the security underlying the Depository Receipts to issue and service
such Depository Receipts (unsponsored Depository Receipts), there may be an
increased possibility that the Fund would not become aware of and be able to
respond to corporate actions, such as stock splits or rights offerings involving
the foreign issuer, in a timely manner. In addition, the lack of information may
result in inefficiencies in the valuation of such instruments. Investment in
Depository Receipts does not eliminate all the risks inherent in investing in
securities of non-U.S. issuers. The market value of Depository Receipts is
dependent upon the market value of the underlying securities and fluctuations in
the relative value of the currencies in which the Depository Receipt and the
underlying securities are quoted. However, by investing in Depository Receipts,
such as ADRs, that are quoted in U.S. dollars, a Fund will avoid currency risks
during the settlement period for purchases and sales.

                                      -23-
<PAGE>
 

         Foreign Currency Transactions. Because investment in foreign issuers
         -----------------------------
will usually involve currencies of foreign countries, and because the
International Equity, Global Income and High Yield Funds may have currency
exposure independent of their securities positions, the value of the assets of a
Fund as measured in U.S. dollars will be affected by changes in foreign currency
exchange rates. A Fund may, to the extent it invests in foreign securities,
purchase or sell foreign currencies on a spot basis and may also purchase or
sell forward foreign currency exchange contracts for hedging purposes and to
seek to protect against anticipated changes in future foreign currency exchange
rates. In addition, the International Equity, Global Income and High Yield Funds
may enter into such contracts to seek to increase total return when the
Investment Adviser anticipates that the foreign currency will appreciate or
depreciate in value, but securities denominated or quoted in that currency do
not present attractive investment opportunities and are not held in the Fund's
portfolio. When entered into to seek to enhance return, forward foreign currency
exchange contracts are considered speculative. The International Equity, Global
Income and High Yield 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 correlation between the two currencies. If a Fund enters into a
forward foreign currency exchange contract to buy foreign currency for any
purpose or enters into forward foreign currency exchange contracts to sell
foreign currency to seek to increase total return, the Fund will be required to
place cash or liquid assets in a segregated account with the Fund's custodian in
an amount equal to the value of the Fund's total assets committed to the
consummation of the forward contract. A Fund will incur costs in connection with
conversions between various currencies. A Fund may hold foreign currency
received in connection 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, based on anticipated changes in the
relevant exchange rate.

         Currency exchange rates may fluctuate significantly over short periods
of time causing, along with other factors, a Fund's net asset value to
fluctuate. Currency exchange rates 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 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 U.S. 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 

                                      -24-
<PAGE>
 
susceptible to the risk of adverse economic and political developments within
those countries.

         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 obligations.
Since these contracts are not guaranteed by an exchange or clearinghouse, a
default on the contract would deprive the 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, currency swaps
or other privately negotiated currency instruments 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.

         The Funds may also engage in a variety of foreign currency management
techniques. Due to the limited market for instruments in emerging markets, the
Investment Adviser does not currently anticipate that a significant portion of
the Funds' currency exposure in emerging markets, if any, will be covered by
such instruments.

FIXED INCOME SECURITIES

         U.S. Government Securities. Each Fund may invest in U.S. Government
         --------------------------
securities. Generally, these securities include U.S. Treasury obligations and
obligations issued or guaranteed by U.S. Government agencies, instrumentalities
or sponsored enterprises which are 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 Association), (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. No assurance can be given that the U.S. Government will provide
financial support to U.S. Government agencies, instrumentalities or sponsored
enterprises in the future.

         U.S. Government securities also include Treasury receipts and other
stripped U.S. Government securities, where the interest and principal components
of stripped U.S. Government securities are traded independently. The most widely
recognized program is the Separate Trading of Registered Interest and Principal
of Securities Program. A Fund may also invest in zero coupon U.S. Treasury
securities and in zero coupon securities issued by 

                                      -25-
<PAGE>
 
financial institutions, which represent a proportionate interest in underlying
U.S. Treasury securities.

         Foreign Government Securities. The International Equity, Global Income
         -----------------------------
and High Yield Funds may invest in debt obligations of foreign governments and
governmental agencies, including those of Emerging Countries. Investment in
sovereign debt obligations involves special 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 debt,
and a Fund may have limited recourse in the event of a default. Periods of
economic uncertainty may result in the volatility of market prices of sovereign
debt, and in turn a Fund's net asset value, 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 availability 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 sovereign debtor's policy toward international
lenders and the political constraints to which a sovereign debtor may be
subject.

         Asset-Backed Securities. Each Fund (other than the CORE Funds) may also
         -----------------------
invest in asset-backed securities ("Asset-Backed Securities"). The principal and
interest payments on Asset-Backed Securities are collateralized by pools of
assets such as auto loans, credit card receivables, leases, installment
contracts and personal property. Such asset pools are securitized through the
use of special purpose trusts or corporations. Principal and interest payments
may be credit enhanced by a letter of credit, a pool insurance policy or a
senior/subordinated structure.

         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-

                                      -26-
<PAGE>
 
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.

         Municipal Securities. The High Yield Fund may make limited investments
         --------------------
in instruments issued by state and local governmental issuers. The securities
may include private activity bonds, municipal leases, certificates of
participation and "auction rate" securities.

         Corporate Debt Obligations. Each Fund may invest in corporate debt
         --------------------------
obligations. In addition to obligations of corporations, corporate debt
obligations include securities issued by banks and other financial institutions.
Corporate debt obligations are subject to the risk of an issuer's inability to
meet principal and interest payments on the obligations.

         Bank Obligations. Each Fund may invest in obligations issued or
         ----------------
guaranteed by U.S. or foreign banks. Bank obligations, including without
limitation time deposits, bankers' acceptances and certificates of deposit, may
be general obligations of the parent bank or may be limited to the issuing
branch by the terms of the specific obligations or by government regulation.
Banks are subject to extensive but different governmental regulations which may
limit both the amount and types of loans which may be made and interest rates
which may be charged. In addition, the 

                                      -27-
<PAGE>
 
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 operation of this industry.

         Structured Securities. Each Fund may invest in structured securities.
         ---------------------
The value of the principal of and/or interest on such securities 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 References. The interest rate or the principal
amount payable upon maturity or redemption may be increased or decreased
depending upon changes in the applicable Reference. The terms of the structured
securities may provide that in certain circumstances no principal is due at
maturity and, therefore, result in the loss of a Fund's investment. 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 addition, 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 entail a greater degree
of market risk than other types of fixed-income securities. Structured
securities may also be more volatile, less liquid and more difficult to
accurately price than less complex securities.

         Rating Criteria. The rating criteria for the Global Income and High
         ---------------
Yield Funds are stated above. Except as noted below, each Equity Fund (other
than the CORE Funds, which only invest in debt instruments that are cash
equivalents) may invest in debt securities rated at least investment grade at
the time of investment. Investment grade debt securities are securities rated
BBB or higher by Standard & Poor's or Baa or higher by Moody's. 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, determined by the Investment Adviser to be
of comparable credit quality. The Growth and Income, Capital Growth and
International Equity Funds may invest up to 10%, 10% and 35%, respectively, of
their total assets in debt securities which are unrated or rated in the lowest
rating categories by Standard & Poor's or Moody's (i.e., BB or lower by Standard
& Poor's or Ba or lower by Moody's), including securities rated D by Moody's or
Standard & Poor's. The Mid Cap Equity Fund may invest up to 10% of its total
assets in below investment grade debt securities rated B or higher by Standard &
Poor's or B or higher by Moody's. Fixed income securities rated BBB or Baa are
considered medium-grade obligations with speculative characteristics, and
adverse 

                                      -28-
<PAGE>
 
economic conditions or changing circumstances may weaken their issuers'
capacity to pay interest and repay principal. Fixed income securities rated BB
or Ba or below (or comparable unrated securities) are commonly referred to as
"junk bonds," are considered predominately speculative and may be questionable
as to principal and interest payments as described further below under "Risk
Factors - Risks of Investing in Non-Investment Grade Fixed-Income Securities."
As a result, investment in such bonds will entail greater speculative risks than
those associated 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
rating organization, the market price and liquidity of such security may be
adversely affected. See Appendix A to the Additional Statement for a description
of the corporate bond ratings assigned by Standard & Poor's and Moody's.

         Zero Coupon, Deferred Interest, Pay-In-Kind and Capital Appreciation
         --------------------------------------------------------------------
Bonds. The Equity and Fixed Income Funds may invest in zero coupon bonds and the
- -----
Fixed Income Funds may invest in deferred interest, pay-in-kind and capital
appreciation bonds. Zero coupon, deferred interest and capital appreciation
bonds are securities issued at a discount from their face value because interest
payments are typically postponed until maturity. The amount of the discount rate
varies depending on factors including the time remaining until maturity,
prevailing interest rates, the security's liquidity and the issuer's credit
quality. These securities also may take the form of debt securities that have
been stripped of their interest payments. Pay-in-kind securities are securities
that have interest payable by the delivery of additional securities. The market
prices of zero coupon, deferred interest, pay-in-kind and capital appreciation
bonds generally are more volatile than the market 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. A Fund's investments in zero coupon, deferred interest, pay-in-kind and
capital appreciation bonds may require the Fund to sell certain of its portfolio
securities to generate sufficient cash to satisfy certain income distribution
requirements. See "Taxation" in the Additional Statement.

MORTGAGE-BACKED SECURITIES

         Each Fund (other than the CORE Funds) may invest in mortgage-backed
securities ("Mortgage-Backed Securities"), which represent direct or indirect
participations in, or are collateralized by and payable from, mortgage loans
secured by real property. Mortgagors can generally prepay interest or principal
on their mortgage whenever they choose. Therefore, Mortgage-Backed Securities
are often subject to more rapid repayment than their stated maturity date would
indicate as a result of principal prepayments on the underlying loans. This can
result in significantly greater price and yield volatility 

                                      -29-
<PAGE>
 
than is the case with traditional fixed-income securities. During periods of
declining interest rates, prepayments can be expected to accelerate, and thus
impair a Fund's ability to reinvest the returns of principal at comparable
yields. Conversely, in a rising interest rate environment, a declining
prepayment rate will extend the average life of many Mortgage-Backed Securities
and prevent a Fund from taking advantage of such higher yields.

         Fixed-Rate Mortgage Loans. Generally, fixed-rate mortgage loans pay
         -------------------------
interest at fixed annual rates and have original terms to maturity ranging from
5 to 40 years. Fixed-rate mortgage loans typically 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.

         Adjustable Rate Mortgage Loans ("ARMs"). ARMs are pass-through mortgage
         ---------------------------------------
securities collateralized by mortgages with adjustable rather than fixed coupon
rates. ARMs generally provide for a fixed initial mortgage interest rate for a
set period. Thereafter, the interest rates are subject to periodic adjustments
based on changes to a designated benchmark index.

         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. Therefore, the value of an ARM is unlikely to rise during periods of
declining interest rates to the same extent as fixed-rate securities. Interest
rate declines may result in accelerated prepayment of mortgages with the result
that proceeds from prepayments will be reinvested at lower interest rates.
During periods of rising interest rates, changes in the coupon rate 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 investments in ARMs may fluctuate more substantially since
these limits may prevent the security from fully adjusting its interest rate to
the prevailing market rates.

         U.S. Government Guaranteed Mortgage-Backed Securities. Certain 
         -----------------------------------------------------
Mortgage-Backed Securities are issued or guaranteed by the U.S. Government, its
agencies, instrumentalities or sponsored enterprises. Such issuers include, but
are not limited to, Ginnie Mae, Fannie Mae and Freddie Mac. See "U.S. Government
Securities."

                                      -30-
<PAGE>
 
         Privately Issued Mortgage-Backed Securities. Certain Mortgage-Backed
         -------------------------------------------
Securities are issued or sponsored by non-governmental entities. Privately
issued Mortgage-Backed Securities are generally backed by pools of conventional
(i.e., non-government guaranteed or insured) mortgage loans. Since such
Mortgage-Backed Securities normally are not guaranteed by an entity having the
credit standing of Ginnie Mae, Fannie Mae or Freddie Mac, in order to receive a
high quality rating from the rating organizations (i.e., S&P or Moody's), they
normally are structured with one or more types of "credit enhancement."

         Multiple Class Mortgage-Backed Securities and Collateralized Mortgage
         ---------------------------------------------------------------------
Obligations. Mortgage-Backed Securities also 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, each with a specified fixed or floating interest rate and a
final scheduled distribution date. In most cases, payments of principal are
applied to the CMO classes in the order of their respective stated maturities,
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 Internal Revenue Code of
1986, as amended (the "Code"), and invests in certain mortgages principally
secured by interests in real property and other permitted investments. The Funds
do not intend to purchase residual interests in REMICs.


         Stripped Mortgage-Backed Securities. The Global Income and High Yield
         -----------------------------------
Funds may invest in 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 principal payments from a pool
of mortgage loans. If the underlying mortgage loans experience different than
anticipated prepayments of principal, a Fund may fail to fully recoup its
initial investment in these 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 receives all or
most of the interest from mortgage loans 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.

                             INVESTMENT TECHNIQUES

OPTIONS ON SECURITIES AND SECURITIES INDICES


         Each Fund (other than the CORE U.S. Equity and CORE Large Cap Growth
Funds) may write (sell) covered call and put options and purchase call and put
options on any securities in which it may invest or on any securities index
comprised of securities in which it may invest. 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 manage 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 significantly increase a Fund's portfolio turnover
rate and, therefore, associated brokerage commissions or spreads.

OPTIONS ON FOREIGN CURRENCIES


         A Fund may, to the extent it invests in foreign securities, purchase
and sell (write) call and put options on foreign currencies for the purpose of
protecting against declines in the U.S. dollar value of foreign portfolio
securities and anticipated dividends on such securities and against increases in
the U.S. dollar cost of foreign securities to be acquired.

         In addition, the International Equity, Global Income and High Yield
Funds may use options on currency to cross-hedge, which involves writing or
purchasing options on one currency to hedge against changes in exchange rates
for a different currency, if there is a pattern of correlation between the two
currencies. As with other kinds of options transactions, however, the writing of
an option on a 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, 

                                      -32-
<PAGE>
 
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 to purchasing call and put options for hedging purposes, the
International Equity, Global Income and High Yield Funds may purchase call or
put options on currency to seek to increase total return when the Investment
Adviser anticipates that the currency will appreciate or depreciate in value,
but the securities quoted or denominated in that currency do not present
attractive investment opportunities and are not held in the Fund's portfolio.
When purchased or sold to seek to increase total return, options on currencies
are considered speculative. Options on foreign currencies written or purchased
by the Funds are traded on U.S. and foreign exchanges or over-the-counter.

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

         To seek to increase total return or to hedge against changes in
interest rates, securities prices or currency exchange rates, a 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 such contracts
and options. The futures contracts may be based on various securities (such as
U.S. Government securities), foreign currencies, securities indices and other
financial instruments and indices. The CORE U.S. Equity, CORE Large Cap Growth
and CORE Small Cap Equity Funds may enter into such transactions only with
respect to the S&P 500 Index in the case of the CORE U.S. Equity Fund and a
representative index in the case of the CORE Large Cap Growth and CORE Small Cap
Equity Funds.

         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 purchase 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 outstanding positions
in futures and related options entered into for the purpose of seeking to
increase total return would exceed 5% of the market value of the Fund's net
assets. These transactions 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 and maintain cash or liquid assets
with a value equal to the amount of the Fund's obligations or to otherwise cover
the obligations in a manner permitted by the SEC.

         While transactions in futures contracts and options on futures may
reduce certain risks, such transactions themselves entail certain other risks.
See "Investment Objectives and 

                                      -33-
<PAGE>
 
Policies-Futures Contracts and Options on Future Contracts" in the Additional
Statement. Thus, 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 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 net asset value. The
profitability of a Fund's trading in futures to seek to increase total return
depends upon the ability of the Investment Adviser to correctly analyze the
futures markets. In addition, because 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. Further, futures contracts
and options on futures may be illiquid, and exchanges may limit fluctuations in
futures contract prices during a single day.

CURRENCY SWAPS

         The International Equity, Global Income and High Yield Funds may enter
into currency swaps for hedging purposes or to seek to increase total return.
Currency swaps involve the exchange by a Fund with another party of their
respective rights to make or receive payments in specified currencies. Currency
swaps usually involve the delivery of a gross payment stream in one designated
currency in exchange for the gross payment stream in another designated
currency. Therefore, the entire payment stream under a currency swap is subject
to the risk that the other party to the swap will default on its contractual
delivery obligations.

         A Fund will not enter into swap transactions unless the unsecured
commercial paper, senior debt or claims-paying ability of the other party
thereto is rated either AA or A-1 or better by S&P or Aa or P-1 or better by
Moody's, or, if unrated by such rating organizations, determined to be of
comparable quality by the Investment Adviser. The use of currency swaps 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 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. The 
investment advisers, under the supervision of the Board of Trustees, are 
responsible for determining and monitoring the liquidity of the Funds' 
transactions in swaps.

                                      -34-
<PAGE>
 
WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS

         Each Fund may purchase when-issued securities. When-issued transactions
arise when securities are purchased by a Fund with payment and delivery taking
place in the future in order to secure what is considered to be an advantageous
price and yield to the Fund at the time of entering into the transaction. Each
Fund may also purchase securities on a forward commitment basis; that is, make
contracts to purchase securities for a fixed price at a future date beyond the
customary three-day settlement period. A Fund is required to hold and maintain
in a segregated account with the Fund's custodian until three days prior to the
settlement date, cash or 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. 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 prior to the settlement date. Although
a Fund would 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 its Investment Adviser deems it appropriate to do so.

ILLIQUID AND RESTRICTED SECURITIES

         A Fund will not invest more than 15% of its net assets in illiquid
investments, which include securities (both foreign and domestic) that are not
readily marketable, certain SMBS, repurchase agreements maturing in more than
seven days, time deposits with a notice or demand period of more than seven
days, certain over-the-counter options and certain restricted securities, unless
it is determined, based upon the continuing review of the trading markets for a
specific restricted security, that such restricted security is eligible for
resale under Rule 144A under the Securities Act of 1933 and, therefore, is
liquid.

         The Trustees have adopted guidelines and delegated to the Investment
Advisers the daily function of determining and monitoring the liquidity of
portfolio securities. The Trustees, however, retain oversight focusing on
factors such as valuation, liquidity and availability of information and are
ultimately responsible for each determination. Investing in restricted
securities eligible for resale pursuant to Rule 144A may decrease the liquidity
of a Fund's portfolio 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 

                                      -35-
<PAGE>
 
a discount, which may be significant, from the market price of comparable
securities for which a liquid market exists.

REPURCHASE AGREEMENTS

         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. The International Equity, Global Income and High
Yield Funds may also enter into repurchase agreements involving certain foreign
government securities. 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 in connection with the related
repurchase agreement are less than the repurchase price. In addition, in the
event of bankruptcy of the seller or failure of the seller to repurchase the
securities as agreed, a Fund could suffer losses, including loss of interest on
or principal of the security and costs associated with delay and enforcement of
the repurchase agreement.

The Trustees have reviewed and approved certain counterparties whom they believe
to be creditworthy and have authorized the Funds to enter into repurchase
agreements with such counterparties. In addition, each Fund, together with other
registered investment companies having management agreements with an Investment
Adviser, 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.

LENDING OF PORTFOLIO SECURITIES

         Each Fund may also seek to increase its income by lending portfolio
securities. Under present regulatory policies, such loans may be made to
institutions, such as certain broker-dealers, and are required to be secured
continuously by collateral in cash, cash equivalents, or U.S. Government
securities maintained on a current basis in an amount at least equal to the
market value of the securities loaned. Cash collateral may be invested in cash
equivalents. If an 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. A Fund may experience a loss or 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.

SHORT SALES AGAINST THE BOX

         Each Fund (other than the CORE and Fixed Income Funds) may make short
sales of securities or maintain a short position, provided that at all times
when a short position is open the Fund 

                                      -36-
<PAGE>
 

owns or has the right to obtain an equal amount of such securities or securities
convertible into or exchangeable, without payment of any further consideration,
for an equal amount of the securities of the same issuer as the securities sold
short (a short sale against the box). A short sale against the box will defer
recognition of gain for federal income tax purposes only if the Fund
subsequently closes the short position by making a purchase of the relevant
securities no later than 30 days after the end of the taxable year. Not more
than 25% of a Fund's net assets (determined at the time of the short sale) may
be subject to such short sales. As a result of recent tax legislation, short
sales may not be used to defer the recognition of gain for tax purposes with
respect to appreciated securities in a Fund's portfolio.

MORTGAGE DOLLAR ROLLS

         The Global Income 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 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 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 or fee income plus the interest
earned on the cash proceeds of the securities sold until the settlement date for
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 the Fund. Successful
use of mortgage dollar rolls depends upon the Investment Adviser's ability to
predict correctly interest rates and mortgage prepayments. There is no assurance
that mortgage dollar rolls can be successfully employed. The Fund will hold and
maintain in a segregated account until the settlement date cash or liquid assets
in an amount equal to the forward purchase price. For financial reporting and
tax purposes, the Fund treats mortgage dollar rolls as two separate
transactions; one involving the purchase of a security and a separate
transaction involving a sale. The Fund does not currently intend to enter into
mortgage dollar rolls that are accounted for as a financing.

TEMPORARY INVESTMENTS

         Each Fund may, for temporary defensive purposes, invest 100% of its
total assets (except that the CORE Funds may only hold up to 35% of their
respective total assets) in U.S. Government securities and repurchase agreements
collateralized by U.S. Government securities. The Equity Funds may also, for
temporary defensive purposes invest 100% of their respective total assets

                                      -37-
<PAGE>
 
(except the CORE Funds which may only hold up to 35% of their respective total
assets) in commercial paper rated at least A-2 by Standard & Poor's or P-2 by
Moody's, certificates of deposit, bankers' acceptances, repurchase agreements,
non-convertible preferred stocks, non-convertible corporate bonds with a
remaining maturity of less than one year or, subject to certain tax
restrictions, foreign currencies. The High Yield Fund may for temporary purposes
invest in investment grade securities. When a Fund's assets are invested in such
instruments, the Fund may not be achieving its investment objective.

MISCELLANEOUS TECHNIQUES

         In addition to the techniques and investments described above, each
Fund may, with respect to no more than 5% of its net assets, engage in the
following techniques and investments: (i) other investment companies including
World Equity Benchmark Shares and Standard & Poor's Depository Receipts, (ii)
warrants, stock purchase rights and unseasoned companies (Equity Funds only),
(iii) mortgage swaps and interest rate swaps, caps, floors and collars (Global
Income and High Yield Funds only), (iv) yield curve options and inverse
floating-rate securities (Global Income and High Yield Funds only), (v)

         In addition, each Fund may borrow up to 33-1/3% of its total assets
from banks for temporary or emergency purposes. A Fund may not make additional
investments if borrowings (excluding covered mortgage dollar rolls) exceed 5% of
its total assets. For more information see the Additional Statement.

                                 RISK FACTORS

         Risks of Investing in Small Capitalization Companies. Investing in the
         ----------------------------------------------------
securities of such companies involves greater risk and the possibility of
greater portfolio price volatility. Historically, small market capitalization
stocks and stocks of recently organized companies have been more volatile in
price than the larger market capitalization stocks included in the S&P 500
Index. Among the reasons for the greater price volatility of these small company
and unseasoned stocks are the less certain growth prospects of smaller firms and
the lower degree of liquidity in the markets for such stocks.

         Special Risks of Investments in Emerging Markets. Investing in the
         ------------------------------------------------
securities of issuers in Emerging Countries involves risks in addition to those
discussed under "Description of Securities - Foreign Investments." The
International Equity Fund may invest without limit in the securities of issuers
in Emerging Countries. The High Yield Fund may invest up to 25%, the Growth and
Income 

                                      -38-
<PAGE>
 
and Mid Cap Equity Funds may each invest up to 15% and the Capital Growth and
Global Income Funds may invest up to 10% of their total assets in securities of
issuers in Emerging Countries.

         Emerging Countries 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 volume 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 specific 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
opportunities 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
investment 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. See "Other Investment Companies" in the
Additional Statement.

         Many Emerging Countries may be subject to a greater degree of economic,
political and social instability than is the case in Western Europe, the United
States, Canada, Australia, New Zealand and Japan. Many Emerging Countries do not
have fully democratic governments. For example, 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
periodically used force to suppress civil dissent. Disparities of wealth, the
pace and success of democratization, and ethnic, religious and racial
disaffection, among other factors, have also led to social unrest, violence
and/or labor 

                                      -39-
<PAGE>
 
unrest in some Asian and other Emerging Countries. Unanticipated political or
social developments may affect the values of a Fund's investments. Investing in
Emerging Countries involves the risk of loss due to expropriation,
nationalization, confiscation of assets and property or the imposition of
restrictions on foreign investments and on repatriation of capital invested.
Economies in individual Emerging Countries may differ favorably or unfavorably
from the U.S. economy in such respects as growth of gross domestic product,
rates of inflation, currency valuation, capital reinvestment, resource self-
sufficiency and balance of payments positions. Many Emerging Countries have
experienced currency devaluations and substantial and, in some cases, extremely
high rates of inflation, which have a negative effect on the economies and
securities markets of such 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.

         Brokerage commissions, custodial services and other costs relating to
investment in international securities markets generally are more expensive than
in the United States. 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 may involve a Fund's delivery of securities before receipt
of payment for their sale. In addition, 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 complete its contractual obligations.

         Currently, there is no market or only a limited market for many of the
management techniques and instruments with respect to the currencies and
securities markets of the Emerging Countries. Consequently, there can be no
assurance that suitable instruments for hedging currency and market-related
risks will be available at the times when a Fund wishes to use them.

         Interest Rate Risk. 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.
Volatility of a security's market 

                                      -40-
<PAGE>
 
value will differ depending upon the security's duration, the issuer and the
type of instrument.

         Default Risk/Credit Risk. Investments in fixed-income securities are
         ------------------------
subject to the risk that the issuer could default on its obligations and a Fund
could sustain losses on such investments. A default could impact both interest
and principal payments.

         Call Risk and Extension Risk. Fixed-income securities may be subject to
         ----------------------------
both call risk and extension risk. Call risk (i.e., where the issuer exercises
its right to pay principal on an obligation earlier than scheduled) causes cash
flow to be returned earlier than expected. This typically results when interest
rates have declined, and 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 (i.e., where the issuer exercises its right to pay
principal on an obligation later than scheduled) causes cash flows to be
returned later than expected. This typically results when interest rates have
increased and a Fund will suffer from the inability to invest in higher yielding
securities. Certain types of U.S. Government, Asset-Backed, corporate, foreign,
Mortgage-Backed and municipal securities have this call and/or extension risk.

         The investment characteristics of Mortgage-Backed Securities and
Asset-Backed Securities differ from those of traditional fixed-income securities
because they generally have both call risk (also known as prepayment risk) and
extension risk. Homeowners have the option to prepay their mortgage. Therefore,
the duration of a security backed by home mortgages can either shorten (call
risk) or lengthen (extension risk). Investors are exposed to the fluctuating
principal and interest payments associated with such securities. 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.

         ARMs also have the risk of prepayments. The rate of principal
prepayments with respect to ARMs has fluctuated in recent years. As with
fixed-rate mortgage loans, ARMs may be subject to a greater rate of principal
repayments in a declining interest rate environment. 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. Conversely, if
prevailing interest rates rise significantly, ARMs may prepay more slowly. As
with fixed-rate mortgages, ARM prepayment rates vary in both stable and changing
interest rate environments. There are 

                                      -41-
<PAGE>
 
certain ARMs where the homeowner's payments do not fully cover interest, so the
principal balance increases over time. These "negative amortizing" ARMs may be
subject to greater default risk.

         Derivative Mortgage-Backed Securities. Because derivative
         -------------------------------------
Mortgage-Backed Securities (such as principal-only (POs), interest-only (IOs) or
inverse floating rate securities) are more exposed to mortgage prepayments, they
generally involve a greater amount of risk. Small changes in prepayments can
significantly impact the cash flow and the market value of these securities. The
risk of faster than anticipated prepayments generally 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, particular derivative securities may be
leveraged such that their exposure (i.e., price sensitivity) to interest rate
and/or prepayment risk is magnified.

         Risks of Investing in Non-Investment Grade Fixed-Income Securities.
         ------------------------------------------------------------------
Non-investment grade fixed-income securities 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 securities, also referred to as high yield
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.

         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
established 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 depend to a greater extent on the Investment Adviser's judgment
concerning the creditworthiness of issuers 

                                      -42-
<PAGE>
 
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 more
adversely affected 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 generally
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
appreciation is uncertain.

         The secondary market for non-investment grade fixed-income securities
is concentrated in relatively few market makers 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, market trading volume for high yield
fixed-income securities is generally lower and the secondary market for such
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 market price and a
Fund's ability to dispose of particular portfolio investments. 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 portfolio.

         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

                                      -43-
<PAGE>
 
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 a 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.

         Other Risks. Floating-rate derivative debt securities present more
         -----------
complex types of interest rate risks. For example, range floaters are subject 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.

         Asset-Backed Securities present certain credit 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. There is the possibility that, in some cases,
recoveries on repossessed collateral may not be available to support payments on
these securities.

         Risks of Derivative Transactions. A Fund's transactions, if any, in
         --------------------------------
options, futures, options on futures, swap transactions, structured securities
and currency transactions involve certain risks, including a possible lack
of correlation between changes in the value of hedging instruments and the
portfolio assets being hedged, the potential illiquidity of the markets for
derivative instruments, the risks arising from margin requirements and related
leverage factors associated with such transactions. The use of these management
techniques to seek to increase total return may be regarded as a speculative
practice and involves the risk of loss if the Investment Adviser is incorrect in
its expectation of fluctuations in securities prices, interest rates or currency
prices.

         Foreign Risks. See "Foreign Investments" for a description of the risks
         -------------   
         of investing in foreign securities and currencies.


                           INVESTEMENT RESTRICTIONS


         Each Fund is subject to certain investment restrictions that are
described in detail under "Investment Restrictions" in the Additional Statement.
Fundamental investment restrictions of a Fund cannot be changed without approval
of a majority of the outstanding shares of that Fund. Each Fund's investment
objectives and all policies not specifically designated as 

                                      -44-
<PAGE>
 
fundamental are non-fundamental and may be changed without shareholder approval.
If there is a change in a Fund's investment objectives, shareholders should
consider whether that Fund remains an appropriate investment in light of their
then current financial positions and needs.


         "Diversified"/Non-Diversified Status. Each Fund, except the Global 
          -----------------------------------
Income Fund is a "diversified" fund under the Act. Since the Global Income Fund
is "non-diversified" under the Act, it is subject only to certain federal tax
diversification requirements under Subchapter M as well as under Section 817(h)
(including applicable Treasury Regulations) of the Internal Revenue Code of
1986, as amended (the "Code"). Under Subchapter M of the Code, the 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 at the end of each quarter of its taxable
year and are subject to certain conditions and limitations under the Code. Since
the Global Income Fund is not diversified under the Act, it will be more
susceptible to adverse developments affecting any single issuer. The Growth and
Income, CORE U.S. Equity, CORE Large, Cap Growth, CORE Small Cap Equity, Capital
Growth, Mid Cap Equity, International Equity and High Yield Funds are, in
addition to these tax diversification requirements, also subject to the
diversification requirements arising out of their diversified status under the
Act.

                              PORTFOLIO TURNOVER

         A high rate of portfolio turnover (100% or more) involves
correspondingly greater transaction and related expenses which must be borne by
a Fund and its shareholders. It is anticipated that the annual portfolio
turnover rates of the Growth and Income, CORE U.S. Equity, CORE Large Cap
Growth, CORE Small Cap Equity, Capital Growth, Mid Cap Equity, International
Equity, Global Income and High Yield Funds will generally not exceed 40%, 55%,
80%, 65%, 30%, 40%, 45%, 200% and 100%, respectively. It is anticipated that the
portfolio turnover rate of each Fund will vary from year to year. 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. The Investment Adviser will not consider the
portfolio turnover rate a limiting factor in making investment decisions for a
Fund consistent with the Fund's 

                                      -45-
<PAGE>
 
investment objectives and portfolio management policies. For the Fixed Income
Funds, the portfolio turnover rate includes the effect of entering into mortgage
dollar rolls.

                                  MANAGEMENT

TRUSTEES AND OFFICERS

         The Trustees are responsible for deciding matters of general policy and
reviewing the actions of the Investment Advisers, distributor and transfer
agent. The officers of the Trust conduct and supervise the Funds' daily business
operations. The Additional Statement contains information as to the identity of,
and other information about, the Trustees and officers of the Trust.

INVESTMENT ADVISERS

         Investment Advisers. Goldman Sachs Asset Management ("GSAM"), One New
         -------------------
York Plaza, New York, New York 10004, a separate operating division of Goldman
Sachs, serves as the investment adviser to the CORE Large Cap Growth, CORE Small
Cap Equity, CORE U.S. Equity, Growth and Income, Capital Growth, Mid Cap Equity
and High Yield Funds. Goldman Sachs registered as an investment adviser in 1981.
Goldman Sachs Asset Management International ("GSAMI"), 133 Peterborough Court,
London EC4A 2BB, England, an affiliate of Goldman Sachs, serves as the
investment adviser to the International Equity and Global Income Funds. GSAMI
became a member of the Investment Management Regulatory Organization Limited in
1990 and registered as an investment adviser in 1991. As of October 24, 1997,
GSAM and GSAMI, together with their affiliates, acted as investment adviser or
distributor for assets in excess of $128 billion.

         Under a Management Agreement with each Fund, the applicable Investment
Adviser, subject to the general supervision of the Trustees, provides day-to-day
advice as to the Fund's portfolio transactions. 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.

         In performing its investment advisory services, each Investment
Adviser, while remaining ultimately responsible for the management of the Funds,
may rely upon the asset management division of its Singapore and Tokyo
affiliates for portfolio decisions and management with respect to certain
portfolio securities and is able to draw upon the research and expertise of its
other affiliate offices. In addition, the Investment Advisers will have access
to the research of, and proprietary technical models developed by, Goldman Sachs
and may apply quantitative and qualitative analysis in determining the

                                      -46-
<PAGE>
 
appropriate allocations among the categories of issuers and types of securities.

         Under the Management Agreement, each Investment Adviser also: (i)
supervises all non-advisory operations of each Fund that it advises; (ii)
provides personnel to perform such executive, administrative and clerical
services as are reasonably necessary to provide effective administration of each
Fund; (iii) arranges for at each Fund's expense (a) the preparation of all
required tax returns, (b) the preparation and submission of reports to existing
shareholders, (c) the periodic updating of prospectuses and statements of
additional information and (d) the preparation of reports to be filed with the
SEC and other regulatory authorities; (iv) maintains each Fund's records; and
(v) provides office space and all necessary office equipment and services.

         It is the responsibility of the Investment Adviser to make investment
decisions for a Fund and to place the purchase and sale orders for the Fund's
portfolio transactions in the U.S. and foreign markets. Such orders may be
directed to any broker including, to the extent and in the manner permitted by
applicable law, Goldman Sachs or its affiliates. In effecting purchases and
sales of portfolio securities for the Funds, the Investment Advisers will seek
the best price and execution of a Fund's orders.

         In doing so, where two or more brokers or dealers offer comparable
prices and execution for a particular trade, consideration may be given to
whether the broker or dealer provides investment research or brokerage services
or sells shares of any Goldman Sachs Fund. See the Additional Statement for a
further description of the Investment Advisers' brokerage allocation practices.

         As compensation for its services rendered and assumption of certain
expenses pursuant to separate Management Agreements, GSAM and GSAMI are entitled
to the following fees, computed daily and payable monthly at the annual rates
listed below:

High Yield..............................           .70

         The Investment Advisers to the Growth and Income, CORE U.S. Equity,
CORE Large Cap Growth, CORE Small Cap Equity, Capital Growth, Mid Cap Equity,
International Equity, Global Income and High Yield Funds have voluntarily agreed
to reduce or limit certain "Other Expenses" of such Funds (excluding management
fees, taxes, interest and brokerage fees and litigation, indemnification and
other extraordinary expenses to the extent such expenses exceed .15%, .10%,
 .10%, .15%, .15%, .15%, .25%, .15% and .15% per annum of such Funds' average
daily net assets, respectively. Such reductions or limits, if any, are
calculated monthly on a cumulative basis and may be discontinued or modified by
the applicable Investment Adviser in its discretion at any time.

         Activities of Goldman Sachs and its Affiliates and Other Accounts
         -----------------------------------------------------------------
Managed by Goldman Sachs. The involvement of the Investment Advisers, 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 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 type 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
and in general it is not anticipated that the Investment Advisers will have
access to proprietary information for the purpose of managing a Fund. 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 affiliates and other
accounts achieve significant profits on their trading for proprietary or other
accounts. From time to time, a Fund's activities may be limited because of
regulatory restrictions applicable to Goldman Sachs and its affiliates, and/or
their internal policies designed to comply with such restrictions. See
"Management-Activities of Goldman Sachs and its Affiliates and Other Accounts
Managed by Goldman Sachs" in the Additional Statement for further information.

PERFORMANCE OF SIMILARLY MANAGED MUTUAL FUNDS BY THE INVESTMENT ADVISER

                                      -50-
<PAGE>
 
         Each Fund is newly organized and does not yet have its own performance
record. The Growth and Income, CORE U.S. Equity, CORE Large Cap Growth, CORE
Small Cap Equity, Capital Growth, Mid Cap Equity, International Equity, Global
Income and High Yield Funds, however, have substantially the same investment
objectives, policies, strategies and restrictions as existing investment
portfolios of Goldman Sachs Trust, another registered open-end investment
company managed by the Investment Advisers.

         The following performance is included to provide investors with a
performance record for the Investment Advisers in managing investment portfolios
substantially similar to those of the Funds. The figures do not reflect the
deduction of any insurance fees or charges that are imposed by the insurance
company in connection with its sale of the variable annuity contracts and
variable life insurance policies. Investors should refer to the separate account
prospectuses describing the variable annuity contracts and variable life
insurance policies for information pertaining to those insurance fees and
charges. The insurance separate account fees will reduce the performance of the
Funds. The performance of the Class A Shares of the Growth and Income, CORE U.S.
Equity, CORE Large Cap Growth, CORE Small Cap Equity, Capital Growth,
International Equity, Global Income and High Yield Funds and Institutional
Shares of the Mid Cap Equity Fund of the Goldman Sachs Trust reflects the
deduction of the historical fees and expenses paid by the respective classes of
such funds and not those of the Funds of the Trust. Class A Shares of the
Goldman Sachs Trust are subject to a front end sales load. All performance
quotations are at net asset value. Class A Shares of the Goldman Sachs Trust,
unlike Shares of the Trust, have a .25% Authorized Dealer Service Fee and a 12b-
1 fee of up to .25% which reduce performance. Performance of the CORE Large Cap
Growth Fund for the period from November 1, 1991 to May 1, 1997 is represented
by the performance of a predecessor separate account which was managed by the
Adviser during such period. The performance record of the separate account has
been restated to reflect the expenses applicable to Class A Shares. Prior to May
1, 1997, the separate account was a separate investment advisory account under
discretionary management by the Adviser and had substantially similar investment
objectives, policies and strategies as the Fund. Unlike the Fund, the separate
account was not registered as a investment company under the 1940 Act and
therefore was not subject to certain investment restrictions and operational
requirements that are imposed on investment companies by the 1940 Act. If the
separate account had been registered as an investment company under the 1940
Act, the separate account's performance may have been adversely affected by such
restrictions and requirements. On May 1, 1997, the separate account transferred
a portion of its assets to the Fund in exchange for Fund shares.

         The results shown below reflect the reinvestment of dividends and
distributions, and were calculated in the same manner that will be used by each
Fund to calculate its own performance. Performance reflects fee waivers. In the
absence of fee waivers, performance would be reduced. The investment return and
principal value of an investment will fluctuate so that an investor's shares,
when redeemed, may be worth more or less than their original cost. Past
performance is no guarantee of future results and investors should not consider
this performance data as an indication of or substitute for past or future
performance of the Funds of the Trust.

DISTRIBUTOR

         Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
exclusive distributor (the "Distributor") of each Fund's shares at no cost to
the Funds.

                                      -52-
<PAGE>
 
CUSTODIAN AND TRANSFER AGENT

         State Street Bank and Trust Company, 1776 Heritage Drive, North Quincy,
Massachusetts 02110 provides custodial services for the Funds and Goldman Sachs
provides transfer agency services for the Funds.

                              NET ASSET VALUE

         The net asset value per share of each Fund is calculated by the Fund's
custodian 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 (as
such term is defined under "Additional Information"). Net asset value per share
of each Fund is calculated by determining the net assets belonging to the Fund
and dividing by the number of outstanding shares of the Fund.

         Each Fund's portfolio securities for which accurate market quotations
are readily available are valued on the basis of quotations, which may be
furnished by a pricing service or provided by dealers in such securities, and
other portfolio securities are valued at fair value, 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. The Board of Trustees has determined that the
amortized cost of such securities approximates fair market value.

                                      -53-
<PAGE>
 
                          PERFORMANCE INFORMATION

         From time to time each Fund may publish average annual total return and
the Growth and Income, Global Income and High Yield Funds may publish their
yield and distribution rates in advertisements and communications to
shareholders or prospective investors. Average annual total return is determined
by computing the average annual percentage change in value of $1,000 invested at
the maximum public offering price for specified periods ending with the most
recent calendar quarter, assuming reinvestment of all dividends and
distributions at net asset value. The total return calculation assumes a
complete redemption of the investment at the end of the relevant 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 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 data is
available.

         The Growth and Income, Global Income and High Yield Funds compute their
yield by dividing net investment income earned during a recent thirty-day period
by the product of the average daily number of shares outstanding and entitled to
receive dividends during the period and the maximum offering price per share on
the last day of the relevant period. The results are compounded on a bond
equivalent (semiannual) basis and then annualized. 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. The Growth and Income, Global Income and High Yield Funds'
quotations of distribution rate are calculated by analyzing the most recent
distribution of net investment income for a monthly, quarterly or other relevant
period and dividing this amount by the net asset value per share on the last day
of the period for which the distribution rates are being calculated.

         The investment results of a Fund will fluctuate over time and any
presentation of investment results for any prior period should not be considered
a representation of what an investment may earn or what the Fund's performance
may be in any future period. In addition to information provided in shareholder
reports, the Funds may, in their discretion, from time to time make a list of
their holdings available to investors upon request.

                              SHARES OF THE TRUST

         Each Fund is a series of Goldman Sachs Variable Insurance Trust, which
was formed under the laws of the State of Delaware on September 16, 1997. The
Trustees have authority under the Trust's Declaration of Trust to create and
classify shares of beneficial interests in separate series, without further
action by shareholders. Additional series may be added in the future. The
Trustees also have authority to classify and reclassify any series or portfolio
of shares into one or more classes.

         When issued, shares are fully paid and non-assessable. In the event of
liquidation, shareholders are entitled to share pro rata in the net assets of
the applicable Fund available for distribution to such shareholders. Shares have
no preemptive, subscription or conversion rights. Shareholders are entitled to
one vote per share, provided that, at the option of the Trustees, shareholders
will be entitled to a number of votes based upon the net asset values
represented by their shares. Shares of the Trust are not offered directly to the
general public. The Participating Insurance Companies, not the owners of the
variable annuity contracts or variable life insurance policies or participants
therein, are shareholders of a Fund. However, to the extent required by law, (a)
the Participating Insurance Companies will vote Fund shares held in the Separate
Accounts in a manner consistent with timely voting instructions received from
the holders of variable annuity contracts and variable life insurance policies
and (b) the Participating Insurance Companies will vote Fund shares held in the
Separate Accounts for which no timely instructions are received from the holders
of variable annuity contracts and variable life insurance policies, as well as
shares they own, in the same proportion as those shares for which voting
instructions are received. Fund shares held by unregistered Separate Accounts or
qualified plans will be voted for or against any proposition in the same
proportion as all other Fund shares are voted unless the unregistered Separate
Account's Participating Insurance Company or the plan makes other arrangements.
Additional information concerning voting rights of the participants in the
Separate Accounts are more fully set forth in the Prospectus relating to those
accounts issued by the Participating Insurance Companies.

         Inquiries regarding the Trust may be made in writing to the Trust's
office c/o Goldman Sachs, 85 Broad Street, New York, New York 10004. Holders of
variable annuity contracts and variable life insurance policies issued by
Participating Insurance Companies for which shares of the Funds are the
investment vehicle will receive from the Participating Insurance Companies
unaudited semi-annual financial statements and year-end financial statements
audited by the Trust's independent public accountants. Each report will show the
investments owned by the Funds and the market values of the investments and will
provide other information about the Funds and their operations.

                                      -55-
<PAGE>
 
         The Trust does not intend to hold annual meetings of shareholders.
However, pursuant to the Trust's By-Laws, the recordholders of at least 10% of
the shares outstanding and entitled to vote at a special meeting may require the
Trust to hold such special meeting of shareholders for any purpose and
recordholders may, under certain circumstances, as permitted by the Act,
communicate with other shareholders in connection with requiring a special
meeting of shareholders. 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.


         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 Fund are reflected in
account statements from the Transfer Agent.


                                 EXPENSES

         The Trust is responsible for the payment of its expenses. The expenses
include, without limitation, the fees payable to the Investment Advisers, the
fees and expenses payable to the Trust's custodian and any 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 and auditing fees, expenses of preparing and setting in type
prospectuses, statements of additional information, proxy material, reports and
notices and the printing and distributing of the same to the Trust's
shareholders and regulatory authorities, compensation and expenses of its "non-
interested" Trustees and extraordinary expenses, if any, incurred by the
Trust.

         The imposition of the management fee, as well as other operating
expenses, will have the effect of reducing the total return to investors. From
time to time, an Investment Adviser may waive receipt of its fees and/or
voluntarily assume certain expenses of a Fund, which would have the effect of
lowering that Fund's overall expense ratio and increasing total return to
investors at the time such amounts are waived or assumed, as the case may be.
The Fund will not pay the Investment Adviser at a later time for any amounts
which may be waived, nor will the Fund 

                                      -56-
<PAGE>
 
reimburse the Investment Adviser for any amounts which may be assumed.

                                 TAXATION

         Federal Taxes. Each Fund is treated as a separate corporate entity for
         -------------
tax purposes. Each Fund intends to elect to be treated as a regulated investment
company and each Fund 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.
If for any taxable year a Fund does not qualify for the special federal tax
treatment afforded regulated investment companies, all of the Fund's taxable
income would be subject to tax at regular corporate rates without any deduction
for distributions to shareholders. In such event, a Fund's distributions to
Separate Accounts holding shares of the Fund would be taxable as ordinary income
to the extent of the Fund's current and accumulated earnings and profits. A
failure of a Fund to qualify as a regulated investment company also could result
in the loss of the tax-favored status of variable annuity contracts and variable
life insurance policies that are funded by a Separate Account which invests in
the Fund.

         Under Code Section 817(h), a Separate Account upon which a variable
annuity contract or variable life insurance policy is based must be "adequately
diversified." A Separate Account will be adequately diversified if it complies
with certain diversification tests set forth in Treasury regulations. If a
regulated investment company satisfies certain conditions relating to the
ownership of its shares, a Separate Account investing in such investment company
will be entitled to treat its pro rata portion of each asset of the investment
company as an asset for purposes of these diversification tests. Each Fund
intends to meet these ownership conditions and to comply with the
diversification tests noted above. Accordingly, a Separate Account investing
solely in shares of a Fund will be adequately diversified. However, a failure of
a Fund to meet such conditions and to comply with such tests could cause the
owners of variable annuity contracts and variable life insurance policies based
on such Account to recognize ordinary income each year in the amount of any net
appreciation of such contract or policy during the year (including the annual
cost of life insurance, if any, provided under such policy). For additional
discussion regarding Separate Account diversification see the Additional
Statement.

                                      -57-
<PAGE>
 
         Provided that a Fund and a Separate Account investing in the Fund
satisfy the above requirements, any distributions from the Fund to such Account
will be exempt from current federal income taxation to the extent that such
distributions accumulate in a variable annuity contract or a variable life
insurance contract.

         Persons investing in a variable annuity or variable life insurance
contract should refer to the prospectus with respect to such contract for
further tax information.

         The foregoing discussion of federal income tax consequences is based on
tax laws and regulations in effect on the date of this Prospectus and is subject
to change by legislative or administrative action. Each prospective investor
should consult his or her own tax adviser as to the tax consequences of
investments in the Funds.

                          ADDITIONAL INFORMATION

         The term "a vote of the majority of the outstanding shares" of a Fund
means the vote of the lesser of (i) 67% or more of the shares present at a
meeting, if the holders of more than 50% of the outstanding shares of the Fund
are present or represented by proxy, or (ii) more than 50% of the outstanding
shares of the Fund.

         As used in this Prospectus, 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, Labor Day,
Thanksgiving Day and Christmas Day.
                                   DIVIDENDS

         Dividends from net investment income are declared and paid by each Fund
at least annually. Over the course of the fiscal year, dividends accrued and
paid will constitute all or substantially all of each Fund's net investment
income. Each Fund will pay dividends from net realized capital gains, reduced by
available capital losses, at least annually. All dividends and capital gain
distributions will be automatically reinvested in additional shares of a Fund at
the net asset value of such shares on the payment date, unless a Separate
Account is permitted to hold cash and elects to receive payment in cash. From
time to time, a portion of a Fund's dividends may constitute a return of
capital.

                       PURCHASE AND REDEMPTION OF SHARES

         Investors may purchase or redeem shares of the Funds through variable
annuity contracts and variable life insurance policies 

                                      -58-
<PAGE>
 
offered through the Separate Accounts of Participating Insurance Companies. You
should refer to the prospectus of the Participating Insurance Company's Separate
Account for information on how to purchase a variable annuity contract or
variable life insurance policy, how to select specific Funds of the Trust as
investment options for your contract or policy and how to redeem monies from the
Trust.

         The Separate Accounts of the Participating Insurance Companies place
orders to purchase and redeem shares of the Funds based on, among other things,
the amount of premium payments to be invested and the amount of surrender and
transfer requests (as defined in the prospectus describing the variable annuity
contracts and variable life insurance policies issued by the Participating
Insurance Companies) to be effected on that day pursuant to variable annuity
contracts and variable life insurance policies. Orders received by the Trust are
effected on Business Days. The Separate Accounts purchase and redeem shares of
each Fund at the Fund's net asset value per share calculated as of that same day
although such purchases and redemptions may be executed the next morning.
Redemption proceeds paid by wire transfer will normally be wired in federal
funds on the next business day after the Trust receives actual notice of the
redemption order, but may be paid up to three business days after receipt of
actual notice of the order. The Trust may suspend the right of redemption under
certain extraordinary circumstances in accordance with the rules of the SEC. In
addition, each Fund reserves the right to suspend the offering of its shares for
a period of time, and reserves the right to reject any specific purchase 
order.

         The Funds do not assess any fees when they sell or redeem their shares.
Surrender charges, mortality and expense risk fees and other charges may be
assessed by Participating Insurance Companies under the variable annuity
contracts or variable life insurance policies. These fees should be described in
the Participating Insurance Companies' prospectuses.

         In the future, the Trust may offer shares of one or more of the Funds
(including new Funds that might be added to the Trust) to unregistered Separate
Accounts of various Participating Insurance Companies, to variable annuity
contracts and variable life insurance policies sold solely to qualified pension
and profit-sharing plans and/or sold in non-public offerings. The Trust may
also, in the future, offer shares of one or more of the Funds directly to
qualified pension and profit-sharing plans.

         Shares of the Funds may be sold to and held by Separate Accounts that
fund variable annuity and variable life insurance contracts issued by
unaffiliated Participating Insurance Companies. The Trust's shares may be
offered in connection with mixed funding, extended mixed funding and shared
funding. Mixed funding, extended funding and shared funding may present certain
conflicts of interests between variable annuity owners, variable 

                                      -59-
<PAGE>
 
life insurance policy owners and plan investors. The Trust's Board of Trustees
will monitor the Trust for the existence of any material irreconcilable conflict
of interest. The Trust does not currently anticipate offering shares in
connection with extended mixed funding. In addition, the Trust currently does
not foresee any disadvantages to the holders of variable annuity contracts and
variable life insurance policies arising from the fact that interests of the
holders of variable annuity contracts and variable life insurance policies may
differ due to differences of tax treatment or other considerations or due to
conflicts among the unaffiliated Participating Insurance Companies. If, however,
a material unreconcilable conflict arises between the holders of variable
annuity contracts and variable life insurance policies of unaffiliated
Participating Insurance Companies, a Participating Insurance Company may be
required to withdraw the assets allocable to some or all of the Separate
Accounts from the Funds. Any such withdrawal could disrupt orderly portfolio
management to the potential detriment of such holders. The variable annuity
contracts and variable life insurance policies are described in the separate
prospectuses issued by the Participating Insurance Companies. 


        The Funds and Goldman Sachs each reserves the right to reject any
specific purchase order (including exchanges) or to restrict purchases or
exchanges by a particular purchaser (or group of related purchasers). This may
occur, for example, when a purchaser or a group of purchasers' pattern of
frequent purchases, sales or exchanges of 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 management of a Fund.

                                 INTRODUCTION

    Goldman Sachs Variable Insurance Trust (the "Trust") is an open-end,
management investment company.  Shares of the Trust may be purchased and held by
the separate accounts ("Separate Accounts") of participating life insurance
companies ("Participating Insurance Companies") for the purpose of funding
variable annuity contracts and variable life insurance policies.  Shares of the
Trust are not offered directly to the general public. The following series of
the Trust are described in this Additional Statement: Goldman Sachs Growth and
Income Fund ("Growth and Income Fund"), CORE U.S. Equity Fund ("CORE U.S. Equity
Fund"), Goldman Sachs CORE Large Cap Growth Fund ("CORE Large Cap Growth Fund"),
Goldman Sachs CORE Small Cap Equity Fund ("CORE Small Cap Equity Fund"), Goldman
Sachs Mid Cap Equity Fund ("Mid Cap Equity Fund"), Goldman Sachs Capital Growth
Fund ("Capital Growth Fund"), Goldman Sachs International Equity Fund
("International Equity Fund"), (collectively referred to herein as the "Equity
Funds"), Goldman Sachs Global Income Fund ("Global Income Fund") and Goldman
Sachs High Yield Fund ("High Yield Fund") (collectively referred to herein as
the "Fixed Income Funds" and collectively with the Equity Funds referred to
herein as the "Funds"). 

    Each Fund is a series of Goldman Sachs Variable Insurance Trust, which was
formed under the laws of the state of Delaware on September 16, 1997.  The
Trustees have authority under the Trust's charter to create and classify shares
of beneficial interests in separate series and to classify and reclassify any
series or portfolio of shares into one or more classes, without further action
by shareholders.  Additional series may be added in the future.


    Goldman Sachs Asset Management ("GSAM"), a separate operating division of
Goldman, Sachs & Co. ("Goldman Sachs"), serves as investment adviser to the
Growth and Income, CORE U.S. Equity, CORE Large Cap Growth, CORE Small Cap
Equity, Capital Growth, Mid Cap Equity and High Yield Funds.  Goldman Sachs
Asset Management International ("GSAMI"), an affiliate of Goldman Sachs, serves
as investment adviser to the International Equity and Global Income Funds.  GSAM
and GSAMI are sometimes referred to collectively herein as the "Advisers."
Goldman Sachs serves as each Fund's distributor and transfer agent.  Each Fund's
custodian is State Street Bank and Trust Company ("State Street").

    The following information relates to and supplements the description of each
Fund's investment policies contained in the Prospectus.  See the Prospectus for
a fuller description of the Funds' investment objectives and policies. There is
no assurance that each Fund will achieve its objective.

                                      B-4
<PAGE>
 
                      INVESTMENT OBJECTIVES AND POLICIES

    Each Fund's share price will fluctuate with market, economic and, to the
extent applicable, foreign exchange conditions, so that an investment in any of
the Funds may be worth more or less when redeemed than when purchased.  None of
the Funds should be relied upon as a complete investment program.

CORE U.S. EQUITY, CORE LARGE CAP GROWTH AND CORE SMALL CAP EQUITY FUNDS
- -----------------------------------------------------------------------

    Under normal circumstances, the Funds will invest at least 90% of their
total assets in equity securities.  The investment strategy of the CORE U.S.
Equity, CORE Large Cap Growth and CORE Small Cap Equity Funds will be
implemented to the extent it is consistent with maintaining a Fund's
qualification as a regulated investment company under the Internal Revenue Code.

    Since normal settlement for equity securities is three trading days (for
certain international markets settlement may be longer), the Funds will need to
hold cash balances to satisfy shareholder redemption requests.  Such cash
balances will normally range from 2% to 5% of a Fund's net assets.  The Funds
may purchase futures contracts only with respect to the S&P 500 Index (in the
case of CORE U.S. Equity Fund) and a representative index (in the case of CORE
Large Cap Growth and CORE Small Cap Equity Funds) in order to keep a Fund's
effective equity exposure close to 100%.  For example, if cash balances are
equal to 10% of the net assets, the Fund may enter into long futures contracts
covering an amount equal to 10% of the Fund's net assets.  As cash balances
fluctuate based on new contributions or withdrawals, a Fund may enter into
additional contracts or close out existing positions.

    THE MULTIFACTOR MODEL.  The Multifactor Model is a rigorous computerized
rating system for evaluating equity securities according to a variety of
investment characteristics (or factors).  The factors used by the Multifactor
Model incorporate many variables studied by traditional fundamental analysts and
cover measures of value, growth, momentum, risk (e.g. price/earnings ratio,
book/price ratio, growth forecasts, earnings estimate revisions, price momentum,
volatility and earnings stability).  All of these factors have been shown to
significantly impact the performance of equity securities. 

    Because it includes many disparate factors, the Adviser believes that the
Multifactor Model is broader in scope and provides a more thorough evaluation
than most conventional, value-oriented quantitative models. As a result, the
securities ranked highest by the Multifactor Model do not have one dominant
investment characteristic (such as a low price/earnings ratio); rather, such
securities possess many different investment

                                      B-5
<PAGE>
 
characteristics. By using a variety of relevant factors to select securities,
the Adviser believes that the Fund will be better balanced and have more
consistent performance than an investment portfolio that uses only one or two
factors to select securities.

    The Adviser will monitor, and may occasionally suggest and make changes to,
the method by which securities are selected for or weighted in the Fund.  Such
changes (which may be the result of changes in the Multifactor Model or the
method of applying the Multifactor Model) may include: (i) evolutionary changes
to the structure of the Multifactor Model (e.g., the addition of new factors or
a new means of weighting the factors); (ii) changes in trading procedures (e.g.,
trading frequency or the manner in which the Fund uses futures); or (iii)
changes in the method by which securities are weighted in the Fund.  Any such
changes will preserve the Fund's basic investment philosophy of combining
qualitative and quantitative methods of selecting securities using a disciplined
investment process.

INTERNATIONAL EQUITY FUND
- -------------------------

    International Equity Fund will seek to achieve its investment objective by
investing primarily in equity and equity-related securities of issuers that are
organized outside the United States or whose securities are principally traded
outside the United States.  Because research coverage outside the United States
is fragmented and relatively unsophisticated, many foreign companies that are
well-positioned to grow and prosper have not come to the attention of investors.
GSAMI believes that the high historical returns and less efficient pricing of
foreign markets create favorable conditions for International Equity Fund's
highly focused investment approach.  For a description of the risks of the
International Equity Fund's investments in Asia, see "Investing in Emerging
Markets, including Asia."

    A RIGOROUS PROCESS OF STOCK SELECTION.  Using fundamental industry and
company research, GSAMI's equity team in London, Singapore and Tokyo seeks to
identify companies that may achieve superior long-term returns.  Stocks are
carefully selected for International Equity Fund's portfolio through a three-
stage investment process. Because International Equity Fund is a long-term
holder of stocks, the portfolio managers adjust International Equity Fund's
portfolio only when expected returns fall below acceptable levels or when the
portfolio managers identify substantially more attractive investments.

    Using the research of Goldman Sachs as well as information gathered from
other sources in Europe and the Asia-Pacific region, the Adviser seeks to
identify attractive industries around the world.  Such industries are expected
to have favorable underlying economics and allow companies to generate
sustainable and 

                                      B-6
<PAGE>
 
predictable high returns. As a rule, they are less economically sensitive,
relatively free of regulation and favor strong franchises.

    Within these industries the Adviser seeks to identify well-run companies
that enjoy a stable competitive advantage and are able to benefit from the
favorable dynamics of the industry.  This stage includes analyzing the current
and expected financial performance of the company; contacting suppliers,
customers and competitors; and meeting with management.  In particular, the
portfolio managers look for companies whose managers have a strong commitment to
both maintaining the high returns of the existing business and reinvesting the
capital generated at high rates of return.  Management should act in the
interests of the owners and seek to maximize returns to all stockholders.

    GSAMI's currency team manages the foreign exchange risk embedded in foreign
equities by means of a currency overlay program.  The program may be utilized to
protect the value of foreign investments in sustained periods of dollar
appreciation and to add returns by seeking to take advantage of foreign exchange
fluctuations.

    The members of GSAMI's international equity team bring together years of
experience in analyzing and investing in companies in Europe and the Asia-
Pacific region.  Their expertise spans a wide range of skills including
investment analysis, investment management, investment banking and business
consulting. GSAMI's worldwide staff of over 300 professionals includes portfolio
managers based in London, Singapore and Tokyo who bring firsthand knowledge of
their local markets and companies to every investment decision.

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.

    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
mangers 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, 

                                      B-7
<PAGE>
 
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 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 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 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.  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 & Co.'s 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 14 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 and Moody's Investors Services, Inc.
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 accurately analyze 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 constant 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.  Over the past decade, high
yield bonds have delivered consistently higher yields 

                                      B-9
<PAGE>
 
and total return (and higher volatility) 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. 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.

CORPORATE DEBT OBLIGATIONS
- --------------------------

    Each Fund may, under normal market conditions, invest in corporate debt
obligations, including obligations of industrial, utility and financial issuers.
CORE U.S. Equity, CORE Large Cap Growth and CORE Small Cap Equity Funds may only
invest in debt securities that are cash equivalents. 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.

    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

                                     B-10
<PAGE>
 
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 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 SECURITIES.  Bonds rated BB or below by Standard & Poor's Ratings
Group (Standard & Poor's) or Ba or below by Moody's Investor Service, Inc.
("Moody's") (or comparable rated and unrated securities) 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. 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 tend 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 may not be able
to make use of more traditional methods of financing and 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 

                                     B-11
<PAGE>
 
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 the Growth and Income,
Capital Growth, International Equity, Global Income and High Yield Funds invest,
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.

    Another factor which causes fluctuations in the prices of 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 a 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 a 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 a Fund of its initial investment and any
anticipated income or appreciation is uncertain.  A Fund may be required to
liquidate other portfolio securities to satisfy a Fund's annual distribution
obligations in respect of accrued interest income on securities which are
subsequently written off, even though the 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 

                                     B-12
<PAGE>
 
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 a 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 a Fund's net asset value. 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 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 any 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, a Fund may have to replace such security with
a lower-yielding security, resulting in a decreased return for investors.  In
addition, if a Fund experiences unexpected net redemptions of a Fund's shares,
it may be forced to sell its higher-rated securities, resulting in a decline in
the overall credit quality of the Fund's portfolio and increasing the exposure
of the Fund to the risks of high yield securities.  A Fund may also incur
additional expenses to the extent that it is required to seek recovery upon a
default in the payment of principal or interest on a portfolio security.

    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 Adviser's
credit analysis than would be the case with investments in investment-grade debt
obligations.  The 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 Adviser 

                                     B-13
<PAGE>
 
continually monitors the investments in a 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.

OBLIGATIONS OF THE UNITED STATES, ITS AGENCIES, INSTRUMENTALITIES AND SPONSORED
- -------------------------------------------------------------------------------
ENTERPRISES
- -----------

    Each Fund may invest in U.S. government securities ("U.S. Government
Securities"), which are obligations issued or guaranteed by the U.S. government
and its agencies, instrumentalities or sponsored enterprises. 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 of America.  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 Treasury (such as securities of Federal Home Loan Banks), (b)
the discretionary authority of the U.S. government to purchase the agency's
obligations (such as securities of Federal National Mortgage Association
("Fannie Mae")) 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, 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 substantial secondary market, such participations are regarded as illiquid.
Each Fund may also purchase U.S. Government Securities in private placements,
subject to the Fund's limitation on investment in illiquid securities.

    The Funds may also invest in separately traded principal and interest
components of securities guaranteed or issued by the U.S. Treasury if such
components are traded independently under the separate trading of registered
interest and principal of securities program ("STRIPS").

                                     B-14
<PAGE>
 
BANK OBLIGATIONS
- ----------------


    Each Fund may each invest in obligations issued or guaranteed by United
States and foreign banks.  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.

DEFERRED INTEREST, PAY-IN-KIND AND CAPITAL APPRECIATION BONDS
- -------------------------------------------------------------

    Global Income and High Yield Funds may invest in deferred interest and
capital appreciation bonds and pay-in-kind ("PIK") securities.  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
deferred interest, capital appreciation bonds and PIK securities generally are
more volatile than the market 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. 

    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

                                     B-15
<PAGE>
 
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.

    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.
See "Taxation."

ZERO COUPON BONDS
- -----------------

    A Fund's investments in fixed income securities may include zero coupon
bonds, which are debt obligations issued or purchased at a significant discount
from face value.  The discount approximates the total amount of interest the
bonds would have accrued and compounded over the period until maturity.  Zero
coupon bonds do not require the periodic payment of interest.  Such investments
benefit the issuer by mitigating its need for cash to meet debt service but also
require a higher rate of return to attract investors who are willing to defer
receipt of such cash.  Such investments may experience greater volatility in
market value than debt obligations which provide for regular payments of
interest.  In addition, if an issuer of zero coupon  bonds held by a Fund
defaults, the Fund may obtain no return at all on its investment.  Each Fund
will accrue income on such investments for each taxable year which (net of
deductible expenses, if any) is distributable to shareholders and which, because
no cash is generally received at the time of accrual, may require the
liquidation of other portfolio securities to obtain sufficient cash to satisfy
the Fund's distribution obligations.  See "Taxation."

VARIABLE AND FLOATING RATE SECURITIES
- -------------------------------------

    The interest rates payable on certain fixed income securities in which a
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

                                     B-16
<PAGE>
 
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.

    Global Income and High Yield Funds 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. 

CUSTODIAL RECEIPTS
- ------------------

    Each Fund may, with respect to no more than 5% of net assets, 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 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.

MUNICIPAL SECURITIES
- --------------------

    High Yield Fund may invest in municipal securities. Municipal securities
consist of bonds, notes and other instruments issued by or on behalf of states,
territories and possessions of the United States (including the District of
Columbia) and their political subdivisions, agencies or instrumentalities, the
interest on which is exempt from regular federal income tax. Municipal
securities also include "public activity bonds" or industrial development bonds,
which are issued by or on behalf of public authorities to obtain funds for
privately operated facilities, such as airports and waste disposal facilities,
and, in some cases, commercial and industrial facilities.

                                     B-17
<PAGE>
 

    The yields and market values of municipal securities are determined
primarily by the general level of interest rates, the creditworthiness of the
issuers of municipal securities and economic and political conditions affecting
such issuers.  Due to their tax exempt status, the yields and market prices of
municipal securities may be adversely affected by changes in tax rates and
policies, which may have less effect on the market for taxable fixed-income
securities.  Moreover, certain types of municipal securities, such as housing
revenue bonds, involve prepayment risks which could affect the yield on such
securities.


    Investments in municipal securities are subject to the risk that the issuer
could default on its obligations.  Such a default could result from the
inadequacy of the sources or revenues from which interest and principal payments
are to be made or the assets collateralizing such obligations.  Revenue bonds,
including private activity bonds, are backed only by specific assets or revenue
sources and not by the full faith and credit of the governmental issuer.
 
MORTGAGE LOANS AND MORTGAGE-BACKED SECURITIES
- ---------------------------------------------

    GENERAL CHARACTERISTICS.  Each Fund (other than CORE U.S. Equity, CORE Large
Cap Growth and CORE Small Cap Equity Funds) may invest in Mortgage-Backed
Securities.  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, multifamily (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,
multifamily 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 and yield volatility than is the case with traditional fixed
income securities.  As a result, if a Fund purchases mortgage-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. 

                                     B-18
<PAGE>
 
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, the Advisers 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.

    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 

                                     B-19
<PAGE>
 
protect borrowers from unlimited interest rate and payment increases.

    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 Fund's portfolio and therefore in the net asset value
of each 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 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 conditions, the
    ultimate 

                                     B-20
<PAGE>
 
    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.

                                     B-21
<PAGE>
 
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"), collateralized mortgage obligations and stripped
mortgage-backed securities.  A Fund is permitted to invest in other types of
mortgage-backed securities that may be available in the future to the extent
consistent with its investment policies and objective.

    A Fund's investments in mortgage-backed securities may include securities
issued or guaranteed by the U.S. Government or one of its agencies, authorities,
instrumentalities or sponsored enterprises, such as the Government National
Mortgage Association ("Ginnie Mae"), the Federal National Mortgage Association
("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac").

    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 guaranty, Ginnie Mae is authorized to borrow from the
United States Treasury in an unlimited amount.

    FANNIE MAE CERTIFICATES.  Fannie Mae is a stockholder-owned corporation
chartered under an act of the United States 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 Federal Housing Administration ("FHA") or guaranteed by
the Veterans Administration ("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.

                                     B-22
<PAGE>
 
    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 thirty years.  Substantially all of these mortgage
loans are secured by first liens on one-to-four-family residential properties or
multifamily 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 and
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 

                                     B-23
<PAGE>
 
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.  Each Fund (other than CORE U.S. Equity,
CORE Large Cap Growth, CORE Small Cap Equity and Mid Cap Equity Funds) may
invest in both government guaranteed and privately issued mortgage pass-through
securities ("Mortgage Pass-Throughs"); that is, 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 

                                     B-24
<PAGE>
 
mortgage loans included in a mortgage pool may provide for deferred interest
(i.e., negative amortization), the 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.

         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

                                     B-25
<PAGE>
 
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 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 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 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 

                                     B-26
<PAGE>
 
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.

         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.

         MULTIPLE CLASS MORTGAGE-BACKED SECURITIES AND COLLATERALIZED MORTGAGE
OBLIGATIONS.  A 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 Freddie Mac or 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 

                                     B-27
<PAGE>
 
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 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.

                                     B-28
<PAGE>
 
    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 Global Income and High Yield 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 or by private issuers.  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 the Fund's limitation
on investments in illiquid securities.  A Fund's 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 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

                                     B-29
<PAGE>
 
greater risk that the initial investment will not be fully recouped.

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.

    Like Mortgage-Backed Securities, 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
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 

                                     B-30
<PAGE>
 
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.

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS
- --------------------------------------------------

    Each Fund may purchase and sell futures contracts and may also purchase and
write options on futures contracts.  CORE U.S. Equity, CORE Large Cap Growth and
CORE Small Cap Equity Funds may only enter into such transactions with respect
to the S&P 500 Index, for the CORE U.S. Equity Fund and a representative index
in the case of the CORE Large Cap Growth and CORE Small Cap Equity Funds. The
other Funds may purchase and sell futures contracts based on various securities
(such as U.S. Government securities), securities indices, foreign currencies and
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 Commodity Futures Trading Commission ("CFTC").
All 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.

    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 through the sale of futures contracts to offset a decline in the value of
its current portfolio securities. When rates are falling or 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.  Similarly, each Fund (other than CORE U.S. Equity, CORE
Large Cap Growth and CORE Small Cap Equity Funds) can sell futures contracts on
a specified currency to protect against a decline in the value of such currency
and its portfolio securities which are quoted or denominated in such currency.
Each Fund (other than CORE U.S. Equity, CORE Large Cap Growth and CORE Small Cap
Equity Funds) can purchase futures contracts on foreign currency to establish
the price in U.S. dollars of a security quoted or denominated in such currency
that such Fund has acquired or expects to acquire.

                                     B-31
<PAGE>
 
    Positions taken in the futures market are not normally held to maturity, but
are instead liquidated through offsetting transactions which may result in a
profit or a loss.  While each Fund will usually liquidate futures contracts on
securities or currency in this manner, a Fund may instead make or take delivery
of the underlying securities or currency whenever it appears economically
advantageous for the Fund to do so.  A clearing corporation associated with the
exchange on which futures 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, rate of return or currency exchange rate on portfolio securities or
securities that a Fund owns or proposes to acquire.  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 (other than CORE U.S. Equity, CORE Large Cap Growth and CORE
Small Cap Equity Funds) foreign currency rates that would adversely affect the
dollar value of such Fund's portfolio securities.  Similarly, each Fund (other
than CORE U.S. Equity, CORE Large Cap Growth and CORE Small Cap Equity Funds)
may sell futures contracts on a currency in which its portfolio securities are
quoted or denominated or in one currency to seek to hedge against fluctuations
in the value of securities quoted or denominated in a different currency if
there is an established historical pattern of correlation between the two
currencies.  If, in the opinion of the applicable 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, a Fund 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 Advisers 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 lesser number of futures contracts or
by attempting to achieve only a partial hedge against price changes affecting a
Fund's securities portfolio.  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 such
futures contracts.  This would be done, for example, when a Fund anticipates the
subsequent purchase of 

                                     B-32
<PAGE>
 
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 or rates 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, (upon
exercise of the option) 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.  A Fund 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 transactions and
will engage in related options transactions only for bona fide hedging as
defined in the regulations of the CFTC or to seek to increase total return to
the extent permitted by such regulations.  A Fund will determine that the price
fluctuations in the futures contracts and options on futures used for hedging
purposes are substantially related to price fluctuations in securities held by
the Fund or which it expects to purchase. Except as stated below, each Fund's
futures transactions will be entered into for traditional hedging purposes --
i.e., futures contracts will be sold to protect against a decline in the price
of securities (or the currency in which they are quoted or denominated) that the
Fund owns, or futures contracts will be purchased to protect the Fund against an
increase in the price of securities (or the currency in which they are quoted or

                                     B-33
<PAGE>
 
denominated) it intends to purchase. As evidence of this hedging intent, each
Fund expects that on 75% or more of the occasions on which it takes a long
futures or option position (involving the purchase of futures contracts), the
Fund will have purchased, or will be in the process of purchasing, equivalent
amounts of related securities (or assets quoted or denominated in the related
currency) in the cash market at the time when the futures or options position is
closed out. However, in particular cases, when it is economically advantageous
for a Fund to do so, a long futures position may be terminated or an option may
expire without the corresponding purchase of securities or other assets.

    As an alternative to literal compliance with the bona fide hedging
definition, a CFTC regulation permits a Fund to elect to comply with a different
test. Under this test the aggregate initial margin and premiums required to
establish positions in futures contracts and options on futures to seek to
increase total return may not exceed 5% of the net asset value of such 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.  To the extent consistent  with the requirements of the
Code for maintaining qualification as a regulated investment company for federal
income tax purposes, a Fund will engage in transactions in currency forward
contracts, futures contracts and, for a Fund permitted to do so, related options
transactions only.  (see "Taxation")

    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 with its custodian cash or liquid assets 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,
unanticipated changes in interest rates, 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 difficult to achieve because no futures contracts based on
individual equity or corporate fixed-

                                     B-34
<PAGE>
 
income securities are currently available. 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 for a
Fund to hedge fully or perfectly against currency fluctuations affecting the
value of securities quoted or 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.

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 (other than CORE U.S. Equity
and CORE Large Cap Growth Funds).  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 as long as
the option is outstanding or such Fund will use the other methods described
below.  A 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 would obligate such 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 deposited with
its custodian 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.

    Call and put options written by a Fund will also be considered to be covered
to the extent that the Fund's liabilities under such options are wholly or
partially offset by its rights under call and put options purchased by the Fund
or by an offsetting forward commitment.

    In addition, a written call option or put option may be covered by
maintaining cash or liquid assets (either of which may 

                                     B-35
<PAGE>
 
be quoted or denominated in any currency) in a segregated account, by entering
into an offsetting forward contract and/or by purchasing an offsetting option
which, by virtue of its exercise price or otherwise, reduces a Fund's net
exposure on its written option position.

    A Fund may also write (sell) covered call and put options on any securities
index comprised 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 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. 

    A Fund 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 held in a
segregated account by its custodian) upon conversion or exchange of other
securities in its portfolio.  A Fund may cover call and put options on a
securities index by maintaining cash or liquid assets with a value equal to the
exercise price in a segregated account with its custodian or using the other
methods described above.

    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."

    PURCHASING OPTIONS.  Each Fund (other than the CORE U.S. Equity and CORE
Large Cap Growth Funds) may 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
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 if, during the option period, the value
of such securities exceeded the sum of the exercise price, the premium paid and
transaction costs; otherwise such a Fund 

                                     B-36
<PAGE>
 
would realize either no gain or a loss on the purchase of the call option.

    A Fund would normally purchase put options in anticipation of a decline in
the market value of securities in its portfolio ("protective puts") or in
securities in which it may invest.  The purchase of a put option would entitle a
Fund, in exchange for the premium paid, to sell specified 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 more than cover the premium and transaction costs; otherwise
such a 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 portfolio
securities.

    A Fund would purchase put and call options on securities indices for the
same purposes as it would purchase options on individual securities.  For a
description of options on securities indices, see "Writing Covered Options"
above.

    YIELD CURVE OPTIONS.  Global Income and High Yield Funds, with respect to up
to 5% of their net assets, 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.

    Global Income and High Yield Funds may purchase or write yield curve options
for the same purposes as other options on securities.  For example, Global
Income and High Yield Funds may purchase a call option on the yield spread
between two securities if either 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.  Global Income and High Yield Funds
may also purchase or write yield curve options in an effort to increase their
current income if, in the judgment of the Adviser, the Funds will be able to
profit from movements in the spread between the yields of the 

                                     B-37
<PAGE>
 
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 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 the Global Income and High Yield Funds will
be "covered."  A call (or put) option is covered if a Fund holds another call
(or put) option on the spread between the same two securities and maintains in a
segregated account with its custodian 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 because they
have been only recently introduced, established trading markets for these
options have not yet developed.

    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
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 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 

                                     B-38
<PAGE>
 
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.

    Each 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.  Until such time as the staff of the Securities and Exchange
Commission ("SEC") changes its position, each Fund will treat purchased over-
the-counter options and all assets used to cover written over-the-counter
options as illiquid securities, except that with respect to options written with
primary dealers in U.S. Government securities pursuant to an agreement requiring
a closing purchase transaction at a formula price, the amount of illiquid
securities may be calculated with reference to the formula.

    Transactions by each Fund in options on securities and indices 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 or 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 of the Advisers. 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.

    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 successful use of protective
puts for hedging purposes depends in part on the Adviser's ability to predict
future price fluctuations and the degree of correlation between the options and
securities markets.

REAL ESTATE INVESTMENT TRUSTS
- -----------------------------

    Each Fund other than the Global Income and High Yield Funds may invest in
shares of REITs.  REITs are pooled investment vehicles which invest primarily in
income producing real estate or real estate related loans or interest.  REITs
are generally classified as equity REITs, mortgage REITs or a combination of

                                     B-39
<PAGE>
 
equity and mortgage REITs.  Equity REITs invest the majority of their assets
directly in real property and derive income primarily from the collection of
rents.  Equity REITs can also realize capital gains by selling properties that
have appreciated in value.  Mortgage REITs invest the majority of their assets
in real estate mortgages and derive income from the collection of interest
payments. Like regulated investment companies such as the Funds, REITs are not
taxed on income distributed to shareholders provided they comply with certain
requirements under the Code.  A Fund will indirectly bear its proportionate
share of any expenses paid by REITs in which it invests in addition to the
expenses paid by a Fund.

    Investing in REITs involves certain unique risks.  Equity REITs may be
affected by changes in the value of the underlying property owned by such REITs,
while mortgage REITs may be affected by the quality of any credit extended.
REITs are dependent upon management skills, are not diversified (except to the
extent the Code requires), and are subject to the risks of financing projects.
REITs are subject to heavy cash flow dependency, default by borrowers, self-
liquidation, and the possibilities of failing to qualify for the exemption from
tax for distributed income under the Code and failing to maintain their
exemptions from the Investment Company Act of 1940, as amended (the "Act").
REITs (especially mortgage REITs) are also subject to interest rate risks.

WARRANTS AND STOCK PURCHASE RIGHTS
- ----------------------------------

    Each Fund other than the Global Income Fund may invest up to 5% of its net
assets, calculated at the time of purchase, in warrants or rights (other than
those acquired in units or attached to other securities) which entitle the
holder to buy equity securities at a specific price for a specific period of
time.  A Fund will invest in warrants and rights only if such equity securities
are deemed appropriate by the Adviser for investment by the Fund.  CORE U.S.
Equity, CORE Large Cap Growth and CORE Small Cap Equity Funds have no present
intention of acquiring warrants or rights. Warrants and rights have no voting
rights, receive no dividends and have no rights with respect to the assets of
the issuer.

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

    Investments in foreign securities may offer potential benefits not available
from investments solely in U.S. dollar-denominated or quoted securities of
domestic issuers.  Such benefits may include the opportunity to invest in
foreign issuers that appear, in the opinion of the applicable Adviser, to offer
better opportunity for long-term growth of capital and income than investments
in U.S. securities, the opportunity to invest in

                                     B-40
<PAGE>
 
foreign countries with economic policies or business cycles different from those
of the United States and the opportunity to reduce fluctuations in portfolio
value by taking advantage of foreign stock markets that do not necessarily move
in a manner parallel to U.S. markets.

    Investing in foreign securities involves certain special considerations,
including those set forth below, which are not typically associated with
investing in U.S. dollar-denominated or quoted securities of U.S. issuers.
Investments in foreign securities usually involve currencies of foreign
countries. Accordingly, any Fund that invests in foreign securities 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.  International Equity, Global Income and High Yield Funds
may be subject to currency exposure independent of their securities positions.

    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.

    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 U.S. company.  Volume
and liquidity in most foreign securities markets are less than in the United
States 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 foreign securities exchanges, brokers, dealers and
listed and unlisted companies than 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 

                                     B-41
<PAGE>
 
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 some of a Fund's assets are
uninvested and no return is earned on such assets. The inability of a 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 the Fund
due to subsequent declines in value of the portfolio securities or, if the 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 affect a
Fund's 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,
resource self-sufficiency and balance of payments position.

    Each Fund other than the Global Income and High Yield Funds may invest in
foreign securities which take the form of sponsored and unsponsored American
Depository Receipts ("ADRs") and Global Depository Receipts ("GDRs") and (except
for CORE U.S. Equity, CORE Large Cap Growth, CORE Small Cap Equity, Global
Income and High Yield Funds) may also invest in European Depository Receipts
("EDRs") or other similar instruments representing securities of foreign issuers
(together, "Depository Receipts").

    ADRs represent the right to receive securities of foreign issuers deposited
in a domestic bank or a correspondent bank. ADRs are traded on domestic
exchanges or in the U.S. over-the-counter market and, generally, are in
registered form.  EDRs and GDRs are receipts evidencing an arrangement with a
non-U.S. bank similar to that for ADRs and are designed for use in the non-U.S.
securities markets.  EDRs and GDRs are not necessarily quoted in the same
currency as the underlying security.

    To the extent a Fund acquires Depository Receipts through banks which do not
have a contractual relationship with the foreign issuer of the security
underlying the Depository Receipts to issue and service such Depository Receipts
(unsponsored), there may be an increased possibility that the Fund would not
become aware of and be able to respond to corporate actions such as stock splits
or rights offerings involving the foreign issuer in a timely manner.  In
addition, the lack of information may result in inefficiencies in the valuation
of such instruments.

    Each Fund (except CORE U.S. Equity, CORE Large Cap Growth and CORE Small Cap
Equity Funds) may invest in countries with emerging 

                                     B-42
<PAGE>
 
economies or securities markets. Political and economic structures in many of
such countries may be undergoing significant evolution and rapid development,
and such countries may lack the social, political and economic stability
characteristic of more developed countries. Certain of such countries may have
in the past failed to recognize private property rights and have at times
nationalized or expropriated the assets of private companies. As a result, the
risks described above, including the risks of nationalization or expropriation
of assets, may be heightened. See "Investing in Emerging Markets" below.

    A Fund (other than CORE U.S. Equity, CORE Large Cap Growth and CORE Small
Cap Equity Funds) may invest in securities of issuers domiciled in a country
other than the country in whose currency the instrument is denominated or
quoted.  The Funds may also invest in securities quoted or denominated in the
European Currency Unit ("ECU"), which is a "basket" consisting of specified
amounts of the currencies of certain of the member states of the European
Community.  The specific amounts of currencies comprising the ECU may be
adjusted by the Council of Ministers of the European Community from time to time
to reflect changes in relative values of the underlying currencies.  In
addition, the Funds may invest in securities quoted or denominated in other
currency "baskets."


    INVESTING IN EMERGING MARKETS.  International Equity Fund is intended for
long-term investors who can accept the risks associated with investing primarily
in equity and equity-related securities of foreign issuers, including Emerging
Country issuers, as well as the risks associated with investments quoted or
denominated in foreign currencies.  Growth and Income, Mid Cap Equity and
Capital Growth Funds may invest, to a lesser extent, in equity and equity-
related securities of foreign issuers, including Emerging Country issuers.
Global Income and High Yield Funds may invest in debt securities of foreign
issuers, including Emerging Country issuers. In addition, certain of
International Equity and High Yield Funds' potential investment and management
techniques entail special risks.

    The pace of change in many Emerging Countries, and in particular those in
Asia, over the last 10 years has been rapid. Accelerating economic growth in the
region has combined with capital market development, high government
expenditure, increasing consumer wealth and taxation policies favoring company
expansion.  As a result, stock market returns in many Emerging Countries have
been relatively attractive.   See "Risk Factors" in the Prospectus.

    Each of the securities markets of the Emerging Countries is less liquid and
subject to greater price volatility and has a smaller market capitalization than
the U.S. securities markets. 

                                     B-43
<PAGE>
 
Issuers and securities markets in such countries are not subject to as extensive
and frequent accounting, financial and other reporting requirements or as
comprehensive government regulations as are issuers and securities markets in
the U.S. In particular, the assets and profits appearing on the financial
statements of Emerging Country issuers may not reflect their financial position
or results of operations in the same manner as financial statements for U.S.
issuers. Substantially less information may be publicly available about Emerging
Country issuers than is available about issuers in the United States.

    Certain of the Emerging Country securities markets are marked by a high
concentration of market capitalization and trading volume in a small number of
issuers representing a limited number of industries, as well as a high
concentration of ownership of such securities by a limited number of investors.
The markets for securities in certain Emerging Countries are in the earliest
stages of their development.  Even the markets for relatively widely traded
securities in Emerging Countries may not be able to absorb, without price
disruptions, a significant increase in trading volume or trades of a size
customarily undertaken by institutional investors in the securities markets of
developed countries.  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 accurately price 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. 

    Transaction costs, including brokerage commissions or dealer mark-ups, in
Emerging Countries may be higher than in the United States and other developed
securities markets.  In addition, existing laws and regulations are often
inconsistently applied. As legal systems in Emerging Countries 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.

    Foreign investment in the securities markets of several of the Asian
countries is restricted or controlled to varying degrees. These restrictions may
limit a Fund's investment in certain of the Asian countries and may increase the
expenses of the Fund. Certain Emerging 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
specific class of securities which may have less advantageous terms (including
price) than securities of the company available for purchase by nationals.  
In addition, the

                                     B-44
<PAGE>
 
repatriation of both investment income and capital from several of the Emerging
Countries is subject to restrictions such as the nee for certain governmental
consents. Even where there is no outright restriction on repatriation of
capital, the mechanics of repatriation may affect certain aspects of the
operation of a Fund. A Fund may be required to establish special custodial or
other arrangements before investing in certain emerging countries.

    Each of the Emerging Countries may be subject to a greater degree of
economic, political and social instability than is the case in the United
States, Japan and most Western European countries.  Such instability may result
from, among other things, the following: (i) authoritarian governments or
military involvement in political and economic decision making, including
changes or attempted changes in governments through extra-constitutional means;
(ii) popular unrest associated with demands for improved political, economic or
social conditions; (iii) internal insurgencies; (iv) hostile relations with
neighboring countries; and (v) ethnic, religious and racial disaffection or
conflict.  Such economic, political and social instability could disrupt the
principal financial markets in which the Funds may invest and adversely affect
the value of the Funds' assets.

    The economies of Emerging Countries 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.  Many
Emerging Countries 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 Countries 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 Countries are vulnerable to weakness in
world prices for their commodity exports.

    A Fund's income and, in some cases, capital gains from foreign stocks and
securities will be subject to applicable taxation in certain of the countries in
which it invests, and treaties between the U.S. and such countries may not be
available in some cases to reduce the otherwise applicable tax rates.  See
"Taxation."

    Securities markets of Emerging Countries 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 settlement
could result in temporary periods when a portion of the Fund's assets is 

                                     B-45
<PAGE>
 
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
the Fund due to subsequent declines in value of the portfolio security or, if
the Fund has entered into a contract to sell the security, could result in
possible liability of the Fund to the purchaser.

    SOVEREIGN DEBT OBLIGATIONS.  The International Equity, Global Income and
High Yield Funds may invest in 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 Countries 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.

    FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS.  Growth and Income, Mid Cap
Equity and Capital Growth Funds may enter into forward foreign currency exchange
contracts for hedging purposes. International Equity, 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 

                                     B-46
<PAGE>
 
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 a Fund may either accept or make
delivery of the currency specified in the contract or, at or prior to maturity,
enter into a closing transaction involving the purchase or sale of an offsetting
contract. Closing transactions with respect to forward contracts are usually
effected with the currency trader who is a party to the original forward
contract.

    A 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 denominated or quoted in a foreign currency, or when a Fund
anticipates the receipt in a foreign currency of dividend or interest payments
on such a security which it holds, the 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 dollars, of the amount of foreign
currency involved in the underlying transactions, the Fund will 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 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 such 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.

                                     B-47
<PAGE>
 

    International Equity, 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 quoted or denominated in a different
currency if the Adviser determines that there is a pattern of correlation
between the two currencies.  International Equity, Global Income and High Yield
Funds may also purchase and sell forward contracts to seek to increase total
return when the Adviser anticipates that the foreign currency will appreciate or
depreciate in value, but securities quoted or denominated in that currency do
not present attractive investment opportunities and are not held in the Fund's
portfolio. 

    A Fund's custodian will place cash or liquid assets into a segregated
account of such Fund 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.  If the value of the securities placed in
the segregated account declines, additional cash or liquid assets will be placed
in the account on a daily basis so that the value of the account will equal the
amount of a Fund's commitments with respect to such contracts.  The segregated
account will be marked-to-market on a daily basis.  Although the contracts are
not presently regulated by the 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.  The Global Income and
High Yield Funds will not enter into a forward contract with a term of greater
than one year.

    While a Fund will enter into forward contracts to reduce currency exchange
rate risks, transactions in such contracts involve certain other risks.  Thus,
while the Fund may benefit from such transactions, unanticipated changes in
currency prices may result in a poorer overall performance for the 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
such Fund.  Such imperfect correlation may cause a 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 foreign forward currency contracts offer less protection
against defaults than is available when trading in currency instruments on an
exchange.  

                                     B-48
<PAGE>
 
    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
such transactions 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 Adviser.

    WRITING AND PURCHASING CURRENCY CALL AND PUT OPTIONS. Each Fund (except CORE
U.S. Equity, CORE Large Cap Growth and CORE Small Cap Equity Funds) may write
covered put and call options and purchase put and call options on foreign
currencies for the purpose of protecting against declines in the U.S. dollar
value of portfolio securities and against increases in the U.S. dollar cost of
securities to be acquired.  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 and when a Fund seeks to
close out an option, 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.  Options on foreign currencies to
be written or purchased by a Fund will be traded on U.S. and foreign exchanges
or over-the-counter.

    International Equity, Global Income and High Yield Funds may use options on
currency to cross-hedge, which involves writing or purchasing options on one
currency to hedge against changes in exchange rates for a different currency
with a pattern of correlation.  In addition, International Equity, Global Income
and High Yield Funds may purchase call options on currency to seek to increase
total return when the Adviser anticipates that the currency will appreciate in
value, but the securities quoted or denominated in that currency do not present
attractive investment opportunities and are not included in the Fund's
portfolio.

    A call option written by a Fund obligates a Fund to sell specified currency
to the holder of the option at a specified price if the option is exercised
before the expiration date.  A put option written by a Fund would obligate a
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, 

                                     B-49
<PAGE>
 
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.
For a description of how to cover written put and call options, see "Writing
Covered Options" above.

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

    A Fund would normally purchase call options on foreign currency in
anticipation of an increase in the U.S. dollar value of currency in which
securities to be acquired by a Fund are quoted or denominated.  The purchase of
a call option would entitle the 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.

    A Fund 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
quoted or denominated ("protective puts"). The purchase of a put option would
entitle a Fund, 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 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 underlying currency or portfolio securities.

    In addition to using options for the hedging purposes described above,
International Equity, Global Income and High Yield Funds may use options on
currency to seek to increase total return.  International Equity, Global Income
and High Yield Funds may write (sell) covered put and call options on any
currency in order to realize greater income than would be realized on portfolio
securities transactions alone.  However, in writing covered call options for
additional income, International Equity, 

                                     B-50
<PAGE>
 
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, International Equity, Global Income and High Yield Funds accept, in
return for the option premium, the risk that they may be required to purchase
the underlying currency at a price in excess of the currency's market value at
the time of purchase.

    International Equity, 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.  International Equity, 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, International
Equity, 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 a Fund
for the purpose of benefiting from a decline in the value of currencies which it
does not own. 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. 

    SPECIAL RISKS ASSOCIATED WITH OPTIONS ON CURRENCY. An exchange traded
options position may be closed out only on an options exchange which provides a
secondary market for an option of the same series.  There is no assurance that a
liquid secondary market on an exchange will exist for any particular option, or
at any particular time.  In such event, it might not be possible to effect
closing transactions in particular options, with the result that a Fund would
have to exercise its options in order to realize any profit and would incur
transaction costs upon the sale of underlying currencies pursuant to the
exercise of put options.  If a Fund as a covered call option writer is unable to
effect a closing purchase transaction in a secondary market, it will not be able
to sell the underlying currency (or security quoted or denominated in that
currency) until the option expires or it delivers the underlying currency upon
exercise. 

    There is no assurance that higher than anticipated trading activity or other
unforeseen events might not, at times, render certain of the facilities of the
Options Clearing Corporation inadequate, and thereby result in the institution
by an exchange of special procedures which may interfere with the timely
execution of customers' orders.

    A Fund may purchase and write over-the-counter options to the extent
consistent with its limitation on investments in illiquid securities.  Trading
in over-the-counter options is subject to the 

                                     B-51
<PAGE>
 
risk that the other party will be unable or unwilling to close out options
purchased or written by a Fund.

    The amount of the premiums which a Fund may pay or receive may be adversely
affected as new or existing institutions, including other investment companies,
engage in or increase their option purchasing and writing activities.

MORTGAGE DOLLAR ROLLS
- ---------------------

    Global Income 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, Global Income Fund treats mortgage
dollar rolls as two separate transactions; one involving the purchase of a
security and a separate transaction involving a sale. The Global Income Fund
does 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
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 obligation 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.

CURRENCY SWAPS, MORTGAGE SWAPS, INDEX SWAPS AND INTEREST RATE SWAPS, CAPS,
- --------------------------------------------------------------------------
FLOORS AND COLLARS
- ------------------

    International Equity Fund, with respect to up to 5% of its net assets, and
the Global Income and High Yield Funds may enter into currency swaps for both
hedging purposes and to seek to increase total return. In addition, Global
Income and High Yield Funds may, with respect to no more than 5% of net assets,
enter into mortgage and interest rate swaps and other interest rate swap
arrangements such as rate caps, floors and collars, for hedging purposes or to
seek to increase total return. Currency swaps involve the exchange by a Fund
with another party of their respective rights to make or receive payments in
specified currencies. 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 principal amount, however, is tied to a reference
pool or pools of mortgages. Index swaps involve the exchange by a Fund with
another party of the respective amounts payable with respect to a notional
principal amount at interest rates equal to two specified indices. 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, 

                                     B-53
<PAGE>
 
mortgage 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, mortgage and index 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, index 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, index and mortgage swaps is limited to the
net amount of interest payments that the Fund is contractually obligated to
make.  If the other party to an interest rate, index or mortgage swap defaults,
the Fund's risk of loss consists of the net amount of interest payments that the
Fund is contractually entitled to receive, if any.  In contrast, currency swaps
usually involve the delivery of a gross payment stream in one designated
currency in exchange for the gross payment stream in another designated
currency.  Therefore, the entire payment stream under 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 is held in a segregated account consisting of cash or liquid assets the
Funds and the Advisers believe 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.

    International Equity Fund will not enter into swap transactions unless
the unsecured commercial paper, senior debt or claims paying ability of the
other party thereto is considered to be investment grade by the Adviser.  
Global Income and High Yield Funds will not enter into any swap transactions
unless the unsecured commercial paper, senior debt or claims-paying ability of
the other party is rated either AA or A-1 or better by Standard & Poor's or Aa
or P-1 or better by Moody's or their equivalent ratings.  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 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 Advisers, under the supervision of the
Board of Trustees, are responsible for determining and monitoring the liquidity
of the Funds' transactions in swaps, caps, floors and collars. 

                                     B-54
<PAGE>
 
    The use of interest rate, mortgage, index 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 an 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.

LENDING OF PORTFOLIO SECURITIES
- -------------------------------

    Each Fund may lend portfolio securities.  Global Income and High Yield
Funds may not engage in portfolio securities lending in excess of 5% of net
assets.  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 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
Advisers to be of good standing, and when, in the judgment of the Advisers, the
consideration which can be earned currently from securities loans of this type
justifies the attendant risk.  If the Advisers determine 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 a Fund. 

WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS
- ----------------------------------------------

    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 

                                     B-55
<PAGE>
 
negotiated directly with the other party, and such commitments are not traded on
exchanges. A Fund 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, a Fund 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 also realize a capital gain or
loss in connection with these transactions. For purposes of determining a Fund's
duration, the maturity of when-issued or forward commitment securities will be
calculated from the commitment date. A Fund is required to hold and maintain in
a segregated account with the Fund's custodian until three days prior to the
settlement date, cash and liquid assets in an amount sufficient to meet the
purchase price. Alternatively, a 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.

INVESTMENT IN UNSEASONED COMPANIES
- ----------------------------------

    Each Fund may invest up to 5% of its net assets, calculated at the time of
purchase, in companies (including predecessors) which have operated less than
three years, except that this limitation does not apply to debt securities which
have been rated investment grade or better by at least one nationally recognized
statistical rating organization. The securities of such companies may have
limited liquidity, which can result in their being priced higher or lower than
might otherwise be the case. In addition, investments in unseasoned companies
are more speculative and entail greater risk than do investments in companies
with an established operating record. 

OTHER INVESTMENT COMPANIES
- --------------------------


    Each Equity Fund reserves the right to invest up to 5% of its net and each
Fixed Income Fund reserves the right to invest up to 10% of its total assets,
calculated at the time of investment in the securities of other investment
companies. Each Fixed Income Fund may not invest more than 5% of its total
assets in the securities of any one investment company. No Fund may 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 an Adviser or any of its affiliates serves as investment
adviser. A Fund will indirectly 

                                     B-56
<PAGE>
 

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 the Fund
invests in a money market fund for which an Adviser or any of its affiliates
acts as adviser, the management fee payable by the Fund to an Adviser will be
reduced by an amount equal to the Fund's proportionate share of the advisory and
administration fees paid by such money market fund to the Adviser or any of its
affiliates. 

    Each Equity Fund may also invest in SPDRs.  SPDRs are interests in a unit
investment trust ("UIT") that may be obtained from the UIT or purchased in the
secondary market (SPDRs are listed on the American Stock Exchange).

    The UIT will issue SPDRs in aggregations known as "Creation Units" in
exchange for a "Portfolio Deposit" consisting of (a) a portfolio of securities
substantially similar to the component securities ("Index Securities") of the
Standard & Poor's 500 Composite Stock Price Index (the "S&P Index"), (b) a cash
payment equal to a pro rata portion of the dividends accrued on the UIT's
portfolio securities since the last dividend payment by the UIT, net of expenses
and liabilities, and (c) a cash payment or credit ("Balancing Amount") designed
to equalize the net asset value of the S&P Index and the net asset value of a
Portfolio Deposit.

    SPDRs are not individually redeemable, except upon termination of the UIT.
To redeem, the Portfolio must accumulate enough SPDRs to reconstitute a Creation
Unit.  The liquidity of small holdings of SPDRs, therefore, will depend upon the
existence of a secondary market.  Upon redemption of a Creation Unit, the
Portfolio will receive Index Securities and cash identical to the Portfolio
Deposit required of an investor wishing to purchase a Creation Unit that day.

    The price of SPDRs is derived from and based upon the securities held by the
UIT.  Accordingly, the level of risk involved in the purchase or sale of a SPDR
is similar to the risk involved in the purchase or sale of traditional common
stock, with the exception that the pricing mechanism for SPDRs is based on a
basket of stocks.  Disruptions in the markets for the securities underlying
SPDRs purchased or sold by the Funds could result in losses on SPDRs.  Trading
in SPDRs involves risks similar to those risks, described under "Risks
Associated with Options Transactions," involved in the writing of options on
securities.

    Each Fund (other then CORE U.S. Equity, CORE Large Cap Growth and CORE Small
Cap Equity 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 

                                     B-57
<PAGE>
 
foreign country or region. Each Fund (other than CORE U.S. Equity, CORE Large
Cap Growth and CORE Small Cap Equity Funds) may invest in World Equity Benchmark
Shares ("WEBS") 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 a 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, a 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.

    As with any unsecured debt instrument purchased for a Fund, the Advisers
seek 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), a 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 

                                     B-58
<PAGE>
 
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, a Fund, together with other registered investment companies
having advisory agreements with the 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.

RESTRICTED AND ILLIQUID SECURITIES
- ----------------------------------

    Each Fund may purchase securities that are not registered or 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 includes repurchase agreements maturing in more than seven
days, interest rate, currency and mortgage swaps, interest rate caps, floors and
collars, 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 Advisers the daily function of determining and
monitoring the liquidity of the Funds' portfolio securities.  The Board of
Trustees, however, will retain sufficient oversight and be ultimately
responsible for the determinations.  Since it is not possible to predict with
assurance exactly how the market for Restricted Securities sold and offered
under Rule 144A or Section 4(2) will develop, the Trustees will carefully
monitor the Funds' investments in these securities, focusing on such important
factors, among others, as valuation, liquidity and availability of information.
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
normally reflect a discount from the price at which such securities trade when
they are not restricted, since the restriction makes 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.

                            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 (as defined in the Act) of the outstanding voting
securities of the affected Fund. The investment objective of each Fund and all
other investment policies or practices of each Fund are considered by the Trust
not to be fundamental and accordingly may be changed without shareholder
approval. See "Investment Objectives and Policies" in the Prospectus. For
purposes of the Act, "majority" means the lesser of (a) 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
purposes of the following limitations, 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 Funds'
fundamental investment restriction no. 3, asset coverage of at least 300% (as
defined in the Act), inclusive of any amounts borrowed, must be maintained at
all times.

    A Fund may not:

         (1)  make any investment inconsistent with the Fund's classification as
              a diversified company under the Investment Company Act of 1940, as
              amended (the "Act"). This restriction does not, however, apply to
              any Fund classified as a non-diversified company under the Act;

         (2)  invest 25% or more 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 any of 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

                                     B-60
<PAGE>
 
              by the use of obligations of the U.S. government or any of its
              agencies or instrumentalities;

         (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 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;

         (6)  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;

         (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; or

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

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

                                     B-61
<PAGE>
 
    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:

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

    (b)  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;

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

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

active participation of Goldman Sachs in the world's financial markets enhances
its ability to identify attractive investments.


  The Funds' 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.  With an annual equity research budget approaching
$200 million, the Goldman Sachs Global Investment Research Department covers
approximately 2,010 companies, including approximately 1,142 U.S. corporations
in 60 industries.  The in-depth information and analyses generated by Goldman
Sachs' research analysts are available to the investment advisers. These
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 U.S. 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 option evaluation model analyzes each security's term,
coupon and call

                                     B-68

option, providing an overall analysis of the security's value relative to its
interest risk.

  In managing the Funds, the Funds' investment advisers have access to Goldman
Sachs' economics research.  The Economics Research Department conducts economic,
financial and currency markets research which analyzes economic trends and
interest and exchange rate movement 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 the
Institutional Investor's annual "All British Research Team Survey" in the
following categories:  Economics (U.K.) 1986-1993; Economics/International 1989-
1993; and Currency Forecasting 1986-1993.  In addition, the team has also earned
top rankings in the annual "Extel Financial Survey" of U.K. investment managers
in the following categories: U.K. Economy 1989-1995; International Economies
1986, 1988-1995; International Government Bond Market 1993-1995; and Currency
Movements 1986-1993.

  High Yield Fund's 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 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 Advisers use 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 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 Advisers consider 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 Advisers will first evaluate the absolute
level of a security's OAS considering its liquidity and its interest rate,
volatility and prepayment sensitivity. The Advisers will then analyze its value
relative to alternative investments and to its own investments. The Advisers
will also measure a security's interest rate risk by computing an option
adjusted duration (OAD). The Advisers believe a security's OAD is a better
measurement of its price sensitivity than cash flow duration, which
systematically misstates portfolio duration. The Advisers also evaluate returns
for different mortgage market sectors and evaluate the credit risk of individual
securities. 

                                     B-69
<PAGE>
 
This sophisticated technical analysis allows the Advisers 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
Advisers also expect 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 Advisers also expect to use OAS analytics to evaluate the mortgage market
on an ongoing basis.  Changes in the relative value of various Mortgage-Backed
Securities could suggest tactical trading opportunities for the Funds.  The
Advisers 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 Advisers, 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 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
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

                                     B-70
<PAGE>
 
from time to time may review the credit quality of a Fund's investments.

  In allocating assets among foreign countries and currencies for the Funds
which can invest in foreign securities (in particular, the International Equity
and Global Income Funds), the Advisers 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 Advisers 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' research professionals to produce an optimal currency and asset
allocation for the level of risk suitable for a Fund given its investment
objectives and criteria.
        
  Each Fund's management agreement provides that the Advisers may render similar
services to others as long as the services provided by the Advisers thereunder
are not impaired thereby.

  The Funds' management agreements were approved by the Trustees, including a
majority of the Trustees who are not parties to the management agreement or
"interested persons" (as such term is defined in the Act) of any party thereto
(the "non-interested Trustees"), on October 21, 1997. These arrangements were
approved by the sole shareholder of each Fund on September 26, 1997 by consent
action to satisfy conditions imposed by the SEC in connection with the
registration of shares of the Fund under the Investment Company Act of 1940 and
the Securities Act of 1933. Each management agreement will remain in effect
until June 30, 1999 and 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, and
(b) the vote of a majority of the non-interested Trustees, 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) and
is terminable at any time without penalty by the Trustees or by vote of a
majority of the outstanding voting securities of the affected Fund on 60 days'
written notice to the Adviser and by the Adviser on 60 days' written notice to
the Trust.


  Pursuant to the management agreements the Advisers are entitled to receive the
fees listed below, payable monthly of such Fund's average daily net assets.

     Under the management agreements, each Adviser also: (i) supervises all non-
advisory operations of each Fund that it advises; (ii) provides personnel to
perform such executive, administrative and clerical services as are reasonably
necessary to provide effective administration of each Fund; (iii) arranges for
at each Fund's expense (a) the preparation of all required tax returns, (b) the
preparation and submission of reports to existing shareholders, (c) the periodic
updating of prospectuses and statements of additional information and (d) the
preparation of reports to be filed with the SEC and other regulatory
authorities; (iv) maintains each Fund's records; and (v) provides office space
and all necessary office equipment and services.

     ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED
BY GOLDMAN SACHS.  The involvement of the Advisers 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
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

                                     B-72
<PAGE>
 
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 will 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 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 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 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 Advisers and/or their affiliates
will not initiate or recommend certain types of transactions in certain
securities or instruments with respect to which the Advisers and/or their
affiliates are performing services or when position limits have been reached.

     In connection with their management of the Funds, the Advisers may have
access to certain fundamental analysis and proprietary technical models
developed by Goldman Sachs and other affiliates.  The 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
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 Advisers in managing the Funds.

                                     B-73
<PAGE>
 
     The results of each Fund's investment activities may differ significantly
from the results achieved by the 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 Fund 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 and
investments similar to those in which the Fund invests.

     In addition, certain principals and certain of the employees of the
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.

     Each Adviser may enter into transactions and invest in currencies or
instruments on behalf of a Fund 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 a Fund, 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 or instruments of which may be those
in which a Fund invests or which may be based on the performance of a 

                                     B-74
<PAGE>
 
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 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 Funds. 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.

     It is possible that a Fund's holdings 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 an underwriting or
other distribution of securities of an entity, the Advisers may be prohibited
from purchasing or recommending the purchase of certain securities of that
entity for the Funds.

DISTRIBUTOR
- -----------


     Goldman Sachs serves as the exclusive distributor of the Funds pursuant to
a "best efforts" arrangement as provided by a distribution agreement with the
Trust on behalf of each Fund.  Under the distribution agreement, each Fund is
responsible for, among other things, the payment of all fees and expenses in
connection with the preparation and filing of any registration statement and
prospectus covering the issue and sale of shares, and the registration and
qualification of shares for sale with the SEC and in the various states,
including registering the Fund as a broker or dealer.  Each Fund will also pay
the fees and expenses of preparing, printing and mailing prospectuses annually
to existing shareholders and any notice, proxy statement, report, prospectus or
other communication to shareholders of the Fund, printing and mailing
confirmations of purchases of shares, any issue taxes or any initial transfer
taxes, a portion of toll-free telephone service for shareholders, wiring funds
for share purchases and redemptions (unless paid by the shareholder who
initiates the transaction), printing and postage of business reply 

                                     B-75
<PAGE>
 
envelopes and a portion of the computer terminals used by both the Fund and the
Distributor.

     The Distributor will pay for, among other things, printing and distributing
prospectuses or reports prepared for its use in connection with the offering of
the shares to variable annuity and variable insurance accounts and preparing,
printing and mailing any other literature or advertising in connection with the
offering of the shares to variable annuity and variable insurance accounts.  The
Distributor will pay all fees and expenses in connection with its qualification
and registration as a broker or dealer under federal and state laws, a portion
of the toll-free telephone service and of computer terminals, and of any
activity which is primarily intended to result in the sale of shares issued by
each Fund.

     As agent, the Distributor currently offers shares of each Fund on a
continuous basis to the separate accounts of Participating Insurance Companies
in all states in which such Fund may from time to time be registered or where
permitted by applicable law.  The underwriting agreements provide that the
Distributor accepts orders for shares at net asset value without sales
commission or load being charged.  The Distributor has made no firm commitment
to acquire shares of any Fund.


     Goldman Sachs serves as the Trust's transfer agent.  Under its transfer
agency agreement with the Trust, Goldman Sachs has undertaken with the Trust to
(i) record the issuance, transfer and redemption of shares, (ii) provide
confirmations of purchases and redemptions, and quarterly statements, as well as
certain other statements, (iii) provide certain information to the Trust's
custodian and the relevant sub-custodian in connection with redemptions, (iv)
provide dividend crediting and certain disbursing agent services, (v) maintain
shareholder accounts, (vi) provide certain state Blue Sky and other information,
(vii) provide shareholders and certain regulatory authorities with tax related
information, (viii) respond to shareholder inquires, and (ix) render certain
other miscellaneous services.

INDEPENDENT PUBLIC ACCOUNTANTS
- ------------------------------

     Arthur Andersen LLP, independent public accountants, 225 Franklin Street,
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 AND BROKERAGE

     The Advisers are responsible for decisions to buy and sell securities for
the Funds, the selection of brokers and dealers to effect the transactions and
the negotiation of brokerage commissions, if any.  Purchases and sales of
securities on a securities exchange are effected through brokers who charge a
commission for their services.  Orders may be directed to any broker including,
to the extent and in the manner permitted by applicable law, Goldman Sachs.

     In the over-the-counter market, securities are generally traded on a "net"
basis with dealers acting as principal for their own accounts without a stated
commission, although the price of a security usually includes a profit to the
dealer.  In underwritten offerings, securities are purchased at a fixed price
which includes an amount of compensation to the underwriter, generally referred
to as the underwriter's concession or discount.  On occasion, certain money
market instruments may be purchased directly from an issuer, in which case no
commissions or discounts are paid.

     The portfolio transactions for the Fixed Income 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 the Global Income Fund
and High Yield Fund may invest are traded on exchanges at fixed commission
rates.

     In placing orders for portfolio securities of a Fund, the Advisers are
generally required to give primary consideration to obtaining the most favorable
execution and net price available. This means that an Adviser will seek to
execute each transaction at a price and commission, if any, which provides the
most favorable total cost or proceeds reasonably attainable in the
circumstances. As permitted by Section 28(e) of the Securities Exchange Act of
1934, the Fund may pay a broker which provides brokerage and research services
an amount of disclosed commission 

                                     B-77
<PAGE>
 
in excess of the commission which another broker would have charged for
effecting that transaction. Such practice is subject to (i) a good faith
determination by the Trustees that such commission is reasonable in light of the
services provided; and (ii) to such policies as the Trustees may adopt from time
to time. While the Advisers generally seek reasonably competitive spreads or
commissions, a Fund will not necessarily be paying the lowest spread or
commission available. Within the framework of this policy, the Advisers will
consider research and investment services provided by brokers or dealers who
effect or are parties to portfolio transactions of a Fund, the Advisers and
their affiliates, or their other clients. Such research and investment services
are those which brokerage houses customarily provide to institutional investors
and include research reports on particular industries and companies, economic
surveys and analyses, recommendations as to specific securities and other
products or services (e.g., quotation equipment and computer related costs and
expenses), advice concerning the value of securities, the advisability of
investing in, purchasing or selling securities, the availability of securities
or the purchasers or sellers of securities, furnishing analyses and reports
concerning issuers, industries, securities, economic factors and trends,
portfolio strategy and performance of accounts, effecting securities
transactions and performing functions incidental thereto (such as clearance and
settlement) and providing lawful and appropriate assistance to the Advisers in
the performance of their decision-making responsibilities. Such services are
used by the Advisers in connection with all of their investment activities, and
some of such services obtained in connection with the execution of transactions
for 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 assets are far larger than
those of a Fund, and the services furnished by such brokers may be used by the
Advisers 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 the Fund as well as shares of other investment companies or
accounts managed by the Advisers.  This policy does not imply a commitment to
execute all portfolio transactions through all broker-dealers that sell shares
of the Fund.

     On occasions when an Adviser deems the purchase or sale of a security to be
in the best interest of a Fund as well as its other customers (including any
other fund or other investment company or advisory account for which such
Adviser acts as investment adviser or subadviser), the Adviser, 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 

                                     B-78
<PAGE>
 
other customers in order to obtain the best net price and most favorable
execution under the circumstances. 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 Adviser in the manner it considers to be equitable and
consistent with its fiduciary obligations to such Fund and such other customers.
In some instances, this procedure may adversely affect the price and size of the
position obtainable for a Fund.

     Commission rates in the U.S. are established pursuant to negotiations with
the broker based on the quality and quantity of execution services provided by
the broker in the light of generally prevailing rates.  The allocation of orders
among brokers and the commission rates paid are reviewed periodically by the
Trustees.

     Subject to the above considerations, the Advisers may use Goldman Sachs as
a broker for a Fund.  In order for Goldman Sachs to effect any portfolio
transactions for each 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 securities being purchased or sold on a
securities 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.


                                 NET ASSET VALUE

     Under the Act, the Trustees are responsible for determining in good faith
the fair value of securities of each Fund.  In accordance with procedures
adopted by the Trustees, the net asset value per share of each Fund is
calculated by determining the value of the net assets attributable to that Fund
and dividing by the number of outstanding shares.  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 (as defined in the
Prospectus). 

     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, 

                                     B-79
<PAGE>
 
the Trustees will reconsider the time at which net asset value is computed. In
addition, each 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.

     Portfolio securities of a Fund (except the Global Income Fund) for which no
accurate market quotations are available are valued as follows: (a) securities
listed on any U.S. or foreign stock exchange or on the National Association of
Securities Dealers Automated Quotations System ("NASDAQ") will be valued at the
last sale  price on the exchange or system in which they are principally traded,
on the valuation date.  If there is no sale on the valuation day, securities
traded principally: (i) on a U.S. exchange or NASDAQ will be valued at the mean
between the closing bid and asked prices; and (ii) on a foreign exchange will be
valued at the last sale price (also referred to as the close price).  The last
sale price for securities traded principally on a foreign exchange will be
determined as of the close of the London Stock Exchange or, for securities
traded on exchanges located in the Asia Pacific region, noon London time; (b)
debt securities will be valued via electronic feeds to the custodian bank
containing dealer-supplied bid quotations or bid quotations from a nationally
recognized pricing service; or using another pricing service approved by the
Trustees if such prices are believed by the investment adviser to accurately
represent market value; (c) overnight repurchase agreements will be valued by a
Fund's Investment Adviser at cost; (d) term repurchase agreements (i.e., those
whose maturity exceeds seven days) and interest rate swaps, caps, collars and
floors will be valued at the average of the bid quotations obtained daily from
at least two dealers or, for term repurchase agreements, recognized
counterparties; (e) debt securities with a remaining maturity of 60 days or less
are valued by a Fund's investment adviser 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 then
calculating the mean between the last bid and asked quotations supplied by
certain 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; (h) over-
the-counter options will be valued by an independent unaffiliated broker
identified by the portfolio manager/trader and contacted by the custodian bank;
(i) money market instruments with a remaining maturity of sixty days or less
will be valued by the amortized cost method, which the Trustees have determined
approximates market value; and (j) 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.  For all brokers used in this process, the 

                                     B-80
<PAGE>
 
custodian bank will send a letter to the broker furnishing the quotation. If
accurate quotations are not readily available, such contracts will be valued by
an independent unaffiliated broker identified by the portfolio manager/trader
and contacted by the custodian bank. If broker quotes are used, the portfolio
manager/trader will identify one independent unaffiliated broker from whom the
custodian bank will obtain prices daily and another independent unaffiliated
broker from whom the custodian bank will obtain quotes at least weekly. The
custodian bank will promptly notify the portfolio manager/trader and a member of
the GSAM Valuation Committee or a designee thereof of any deviations equal to or
greater than 3% between the weekly quote and the daily quotes for the date that
the weekly quotes were obtained. The investment adviser will promptly provide
instructions to the custodian bank. For all brokers used in this process, the
custodian bank will send a letter to the broker furnishing the quotation.

     Portfolio securities of the Global Income Fund for which accurate market
quotations are available are valued as follows: (a) securities listed on any
U.S. or foreign stock exchange or on the National Association of Securities
Dealers Automated Quotations System ("NASDAQ") will be valued at the last sale
price on the exchange or system in which they are principally traded, on the
valuation date.  If there is no sale on the valuation day, securities traded
principally: (i) on a U.S. exchange or NASDAQ will be valued at the mean between
the closing bid and asked prices, and (ii) on a foreign exchange will be valued
at the official bid price.  The last sale price and official bid price for
securities traded principally on a foreign exchange will be determined as of the
close of the London Foreign Exchange; (b) over-the-counter securities not quoted
on NASDAQ will be valued at the last sale price on the valuation day or, if no
sale occurs, at the mean between the last bid and asked prices; (c) options and
futures contracts will be valued at the last sale price in the market where such
contract is principally traded; and (d) forward foreign currency exchange
contracts will be valued at the mean between the last bid and asked quotations
supplied by a dealer in such contracts.

     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 

                                     B-81
<PAGE>
 
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.
Events affecting the values of portfolio securities that occur between the time
their prices are determined and the close of regular trading on the New York
Stock Exchange will not be reflected in a Fund's calculation of net asset values
unless the Trustees deem that the particular event would materially affect net
asset value, in which case an adjustment will be made.

     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 or series except where allocations of direct expenses can otherwise be
fairly made.

                                 PERFORMANCE INFORMATION

     A Fund may from time to time quote or otherwise use total return, yield
and/or distribution rate information in advertisements, shareholder reports or
sales literature.  Average annual total return and yield are computed pursuant
to formulas specified by the SEC.

     Yield is computed by dividing net investment income earned during a recent
thirty-day period by the product of the average daily number of shares
outstanding and entitled to receive dividends during the period and the maximum
public offering price per share on the last day of the relevant period.  The
results are compounded on a bond equivalent (semi-annual) basis and then
annualized.  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.

                                     B-82
<PAGE>
 
     The 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 or maximum public offering price 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 at the beginning of the
period, and then calculating the annual compounded rate of return which would
produce that amount, assuming a redemption 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 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.

     Occasionally statistics may be used to specify Fund 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 an average, over a
specified period of time. The premise is that greater volatility connotes
greater risk undertaken in achieving performance.

     From time to time the Trust may publish an indication of a Fund's past
performance as measured by independent sources such as (but not limited to)

unmanaged and the items included in the calculations of such indices and
averages may not be identical to the formulas used by a Fund to calculate its
performance figures.

     A Fund's performance data will be based on historical results and will not
be intended to indicate future performance.  A Fund's total return, yield and
distribution rate will vary based on market conditions, portfolio expenses,
portfolio investments and other factors. The value of a Fund's shares will
fluctuate and an investor's shares may be worth more or less than their 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.


                                 SHARES OF THE TRUST

     Each Fund is a series of Goldman Sachs Variable Insurance Trust, which was
formed under the laws of the state of Delaware on September 16, 1997.

     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, shareholders 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 entitle their holders to one vote per share, are
freely transferable and have no preemptive, subscription or conversion rights.

     The Trustees have authority under the Trust's Declaration of Trust to
create and classify shares of beneficial interests in separate series, without
further action by shareholders.  Additional series may be added in the future.
The Trustees also have authority to classify and reclassify any series or
portfolio of shares into one or more classes.

     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 

                                     B-87
<PAGE>
 
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 elections 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 shareholders of the Trust will
have voting rights only with respect to the limited number of matters specified
in the Declaration of Trust and such other matters as the Trustees may determine
or may be required by law.

     The Declaration of Trust provides for indemnification of Trustees and
officers 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 Declaration of Trust provides that,
if any shareholder or former shareholder of any series is held personally liable
solely 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 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, 

                                     B-88
<PAGE>
 
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 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.

     The 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 Delaware Trust, all the powers and authorities of Trustees under
the Trust Instrument with respect to any other series or class.


        As of the date of this Statement of Additional Information, all of the
outstanding shares of the Trust were owned by The Goldman Sachs Group, L.P., in
connection with the Trust's initial capitalization.

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 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 Declaration of
Trust

                                     B-89
<PAGE>
 
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 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 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 requirements under Delaware law, the 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 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 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
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.


                                 TAXATION

     Shares of the Funds are offered only to Separate Accounts that fund
variable annuity contracts and variable insurance policies issued by
Participating Insurance Companies.  See the Prospectus for such contracts for a
discussion of the special taxation of insurance companies with respect to the
Separate Accounts, the variable annuity contracts, variable insurance policies,
and the holders thereof.

     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 each Fund of the Trust.  This summary does not
address special tax rules 

                                     B-90
<PAGE>
 
applicable to certain classes of investors, such as tax-exempt entities,
insurance companies and financial institutions. Each prospective shareholder is
urged to consult his own tax adviser with respect to the specific federal,
state, local and foreign tax consequences of investing in each Fund. The summary
is based on the laws in effect on the date of this Additional Statement, which
are subject to change.

GENERAL
- -------

     The following is only a summary of certain additional tax considerations
generally affecting each Fund that are not described in the Prospectus.  The
discussions below and in the Prospectus are not intended as substitutes for
careful tax planning.

     The holders of variable life insurance policies or annuity contracts should
not be subject to tax with respect to distributions made on, or redemptions of,
Portfolio shares, assuming that the variable life insurance policies and annuity
contracts qualify under the Code, as life insurance or annuities, respectively,
and that the shareholders are treated as owners of the Fund shares.  Thus, this
summary does not describe the tax consequences to a holder of a life insurance
policy or annuity contract as a result of the ownership of such policies or
contracts.  Policy or contract holders must consult the prospectuses of their
respective policies or contracts for information concerning the federal income
tax consequences of owning such policies or contracts.  This summary also does
not describe the tax consequences applicable to the owners of the Portfolio
shares because the Portfolio shares will be sold only to insurance companies.
Thus, purchasers of Portfolio shares must consult their own tax advisers
regarding the federal, state, and local tax consequences of owning Portfolio
shares.


     Each Fund is a separate taxable entity.  Each of the Funds intends to
qualify for each taxable year as a regulated investment company under Subchapter
M of the Internal Revenue Code, as amended (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 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) such 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 such 

                                     B-91
<PAGE>
 
Fund's 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 such 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. Government securities and securities of other
regulated investment companies) or two or more issuers controlled by the Fund
and engaged in the same, similar or related trades or businesses. For purposes
of the 90% gross income test, income that a Fund earns from equity interests in
certain entities that are not treated as corporations (e.g., partnerships or
trusts) for U.S. tax purposes will generally have the same character for such
Fund as in the hands of such an entity; consequently, a Fund may be required to
limit its equity investments in such entities that earn fee income, rental
income, or other nonqualifying income. In addition, 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 a 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 or swap
contracts for purposes other than hedging currency risk with respect to
securities in a Fund's portfolio or anticipated to be acquired may not qualify
as "directly-related" under these tests.

     If a Fund complies with such provisions, then in any taxable year in which
such Fund 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 accrued original issue discount
and market discount income, income from securities lending, any 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, such Fund (but not its shareholders) will be relieved of
federal income tax on any income of the Fund, including long-term capital gains,
distributed to shareholders. However, if a Fund retains any investment company
taxable income or "net capital gain" (the excess of net long-term capital gain
over net short-term capital loss), it will be subject to a tax at regular
corporate rates on the amount retained. If the Fund retains any net capital
gain, the Fund may designate the retained amount as undistributed capital gains
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 

                                     B-92
<PAGE>
 
for federal incometax 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 the 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 to a
percentage 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, 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 the International Equity or Global Income Funds and
may therefore make it more difficult for such a Fund to satisfy the distribution
requirements described above, as well as the excise tax distribution
requirements described below. However, each Fund generally expects 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, and its
distributions to shareholders will be taxable as ordinary dividends to the
extent of its current and accumulated earnings and profits.

     Each Fund intends to comply with the diversification requirements imposed
by Section 817(h) of the Code and the regulations thereunder.  Under Code
Section 817(h), a variable life insurance or annuity contract will not be
treated as a life insurance policy or annuity contract, respectively, under the
Code, unless the segregated asset account upon which such contract
or policy is based is "adequately diversified."  A segregated asset account will
be adequately diversified if it satisfies one of two alternative tests set forth
in the Treasury Regulations. Specifically, the Treasury Regulations provide
that, except as permitted by the "safe harbor" discussed below, as of the end of
each calendar quarter (or within 30 days thereafter) no more than 55% of the
segregated asset account's total assets may be represented by any one
investment, no more than 70% by any two investments, no more than 80% by any
three investments and no more than 90% by any four investments.  For this
purpose, all securities of the same issuer are considered a single investment,
and each U.S. Government agency and instrumentality is considered a separate
issuer.  As a safe harbor, a segregated asset account will be treated as being
adequately diversified if the diversification requirements under Subchapter M
are satisfied and no more than 55% of the value of the account's total assets
are cash and cash items, U.S. Government securities and securities of 

                                     B-93
<PAGE>
 
other regulated investment companies. In addition, a segregated asset account
with respect to a variable life insurance contract is treated as adequately
diversified to the extent of its investment in securities issued by the United
States Treasury.

     For purposes of these alternative diversification tests, a segregated asset
account investing in shares of a regulated investment company will be entitled
to "look through" the regulated investment company to its pro rata portion of
the regulated investment company's assets, provided that the shares of such
regulated investment company are held only by insurance companies and certain
fund managers (a "Closed Fund").

     If the segregated asset account upon which a variable contract is based is
not "adequately diversified" under the foregoing rules for each calendar
quarter, then (a) the variable contract is not treated as a life insurance
contract or annuity contract under the Code for all subsequent periods during
which such account is not "adequately diversified" and (b) the holders of such
contract must include as ordinary income the "income on the contract" for each
taxable year.  Further, the income on a life insurance contract for all prior
taxable years is treated as received or accrued during the taxable year of the
policyholder in which the contract ceases to meet the definition of a "life
insurance contract" under the Code.  The "income on the contract" is, generally,
the excess of (i) the sum of the increase in the net surrender value of the
contract during the taxable year and the cost of the life insurance protection
provided under the contract during the year, over (ii) the premiums paid under
the contract during the taxable year.  In addition, if a Portfolio
does not constitute a Closed Fund, the holders of the contracts and annuities
which invest in the Portfolio through a segregated asset account may be treated
as owners of Portfolio shares and may be subject to tax on distributions made by
the Portfolio.

     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 all taxable ordinary
income and the excess of capital gains over capital losses for the previous year
that were not distributed for such year and on which the Fund paid no federal
income tax. For federal income tax purposes, dividends declared by a Fund in
October, November or December to shareholders of record on a specified date in
such a month and paid during January of the following year are taxable to such
shareholders as if received on December 31 of the year declared.  The Funds
anticipate that they will generally make timely distributions of income and
capital gains in compliance with these requirements so that they will 

                                     B-94
<PAGE>
 
generally not be required to pay the excise tax. 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.


     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 gains 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, the
Fund may be required to defer the recognition of losses on futures contracts,
forward contracts, and options or underlying securities or foreign currencies to
the extent of any unrecognized gains on related positions held by such 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. Moreover, application of certain requirements for
qualification as a regulated investment company and/or these tax rules to
certain investment practices, such as dollar rolls, or certain derivatives such
as interest rate swaps, floors, caps and collars and currency, mortgage or index
swaps may be unclear in some respects, and a Fund may therefore be required to
limit its participation in such transactions. Certain tax elections may be
available to a Fund 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 a Fund.  Under these rules,
foreign exchange gain or loss realized 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, 

                                     B-95
<PAGE>
 
the resulting loss would not be deductible by the Fund or its shareholders in
future years. Net loss, if any, from certain foregoing 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 a 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 shares
and, once such basis is exhausted, generally giving rise to capital gains.

     A Fund's investment in zero coupon securities, deferred interest
securities, certain structured securities 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, the Fund may be
required to liquidate portfolio securities that it might otherwise have
continued to hold.

     Each Fund (other than CORE U.S. Equity, CORE Large Cap Growth and CORE
Small Cap Equity Funds) anticipates that it will be subject to foreign taxes on
its income (possibly including, in some cases, capital gains) from foreign
securities.  Tax conventions between certain countries and the U.S. may reduce
or eliminate such taxes in some cases.  If, as may occur for International
Equity and Global Income Funds, more than 50% of a Fund's total assets at the
close of any taxable year consists of stock or securities of foreign
corporations, the Fund may file an election with the Internal Revenue Service
pursuant to which shareholders of the 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 the 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.

     If the International Equity and Global Income Funds make this election,
their respective 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 foreign taxes paid by a Fund, 

                                     B-96
<PAGE>
 
although such shareholders will be required to include their shares of such
taxes in gross income if the election is made.

     If a shareholder chooses to take credit for the foreign taxes deemed paid
by such shareholder as a result of any such election by International Equity or
Global Income Funds, 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 entire taxable
income.  For this purpose, distributions from long-term and short-term capital
gains or foreign currency gains by a 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 International Equity and Global Income Funds may not be able to
claim a credit for the full amount of their proportionate share of the foreign
taxes paid by such Fund even if the election is made by such a 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 the International Equity or Global Income Fund files the
election described above, its shareholders will be notified of the amount of (i)
each shareholder's pro rata share of qualified foreign taxes paid by a Fund and
(ii) the portion of Fund dividends which represents income from each foreign
country.  The other Funds will not be entitled to elect to pass foreign taxes
and associated credits or deductions through to their shareholders because they
will not satisfy the 50% requirement described above.  If a Fund cannot or does
not make this election, it may deduct such taxes in computing the amount it is
required to distribute.

     If a Fund acquires stock (including, under proposed regulations, an option
to acquire stock such as is inherent in a convertible bond) in certain foreign
corporations 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
("passive foreign investment companies"), 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 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.  In some cases, elections may be
available that would ameliorate these 

                                     B-97
<PAGE>
 
adverse tax consequences, but such elections would require the Fund to include
certain amounts as income or gain (subject to the distribution requirements
described above) without a concurrent receipt of cash. Each Fund may limit
and/or manage its holdings in passive foreign investment companies to minimize
its tax liability or maximize its return from these investments.

     Investments 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 payments 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.

TAXABLE U.S. SHAREHOLDERS - DISTRIBUTIONS
- -----------------------------------------

     For U.S. federal income tax purposes, distributions by a Fund generally
will be taxable to shareholders who are subject to tax. 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 they would have received had they elected to receive cash and will have
a cost basis in each share received equal to such amount divided by the number
of shares received.


     Distributions from investment company taxable income for the year will be
taxable as ordinary income.  Distributions designated as derived from a Fund's
dividend income, if any, that would be eligible for the dividends-received
deduction if such Fund were not a regulated investment company may be eligible,
for the dividends-received deduction for corporate shareholders. 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
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. Because eligible
dividends are limited to those a Fund receives from U.S. domestic corporations,
it is unlikely that a substantial portion of the distributions made by
International Equity and Global Income Funds will qualify for the dividends-
received deduction.  The entire dividend, including the deducted amount, is
considered in determining the excess, if any, of a corporate shareholder's
adjusted current earnings over its alternative minimum taxable income, which may
increase its liability for the federal alternative minimum tax, and the dividend
may, if it is treated as 

                                     B-98
<PAGE>
 
an "extraordinary dividend" under the Code, reduce such shareholder's tax basis
in its shares of a Fund. Capital gain dividends (i.e., dividends from net
capital gain) if designated as such in a written notice to shareholders mailed
not later than 60 days after a Fund's taxable year closes, will be taxed to
shareholders as long-term capital gain regardless of how long shares have been
held by shareholders, but are not eligible for the dividends received deduction
for corporations. Distributions, if any, that are in excess of a Fund's current
and accumulated earnings and profits will first reduce a shareholder's tax basis
in his shares and, after such basis is reduced to zero, will generally
constitute capital gains to a shareholder who holds his shares as capital
assets.

     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 will be long-term or short-term depending on the shareholder's
tax holding period for the shares 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.  Any loss realized on a sale or
redemption of shares of a Fund may be deferred 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
such Fund.  If deferred, the loss will be reflected in an adjustment to the
basis of the shares acquired.

     Each Fund may be required to withhold, as "backup withholding," federal
income tax at a rate of 31% from dividends (including capital gain dividends)
and share redemption and exchange proceeds to individuals and other non-exempt
shareholders who fail to furnish such Fund with a correct taxpayer
identification number ("TIN") certified under penalties of 

                                     B-99
<PAGE>
 
perjury, or if the Internal Revenue Service or a broker notifies the Fund that
the payee is subject to backup withholding as a result of failing to properly
report interest or dividend income to the Internal Revenue Service or that the
TIN furnished by the payee to the Fund is incorrect, or if (when required to do
so) the payee fails to certify under penalties of perjury that it is not subject
to backup withholding. A Fund may refuse to accept an application that does not
contain any required TIN or certification that the TIN provided is correct. If
the backup withholding provisions are applicable, any such dividends and
proceeds, whether paid in cash or reinvested in additional 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.

STATE AND LOCAL
- ---------------

     Each Fund may be subject to state or local taxes in jurisdictions in which
such Fund may be deemed to be doing business.  In addition, in those states or
localities which have income tax laws, the treatment of such Fund and its
shareholders under such laws may differ from their treatment under federal
income tax laws, and investment in such Fund may have tax consequences for
shareholders different from those of a direct investment in such Fund's
portfolio securities.  Shareholders should consult their own tax advisers
concerning these matters.


                                 OTHER INFORMATION

     Shares of the Funds are offered and sold on a continuous basis by the
Trust's Distributor, Goldman Sachs, acting as agent. As described in the
Prospectus, shares of the Funds are sold and redeemed at their net asset value
as next determined after receipt of the purchase or redemption order.  Each
purchase is confirmed to the Separate Account in a written statement of the
number of shares purchased and the aggregate number of shares currently held.

     Each Fund will normally 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 the 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 purpose using the same method employed in calculating the
Fund's net asset value per share. See "Net Asset Value." If a shareholder
receives redemption proceeds in kind, the shareholder should expect to 

                                     B-100
<PAGE>
 
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 recordation of the transfer of
shares upon the occurrence of any of the foregoing conditions.)

     The Prospectus 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 Prospectus.  Certain

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Shareholder and the Board of Trustees of
Goldman Sachs Variable Insurance Trust:

We have audited the accompanying Statements of Assets and Liabilities of Goldman
Sachs Variable Insurance Trust (comprising, respectively, Growth and Income 
Fund, CORE U.S. Equity Fund, CORE Large Cap Growth Fund, CORE Small Cap Equity 
Fund, Capital Growth Fund, Mid Cap Equity Fund, International Equity Fund, 
Global Income Fund and High Yield Fund) (a Delaware business trust) as of 
December 12, 1997. This financial statement is the responsibility of the Trust's
management. Our responsibility is to express an opinion on this financial 
statement based on our audit.

We conducted our audit 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 statement is free of material 
misstatement. An audit includes examining, on a test basis, evidence supporting 
the amounts and disclosures in the financial statement. 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 audit provides a reasonable basis for our opinion.

In our opinion, the Statements of Assets and Liabilities referred to above 
present fairly, in all material respects, the financial position of Goldman 
Sachs Variable Insurance Trust as of December 12, 1997, in conformity with 
generally accepted accounting principles.

                   THE GOLDMAN SACHS VARIABLE INSURANCE TRUST
                                        
                  Notes to Statement of Assets and Liabilities

                               December 12, 1997

NOTE 1.  ORGANIZATION

     The Goldman Sachs Variable Insurance Trust (the "Trust") was organized on
September 16, 1997 as a Delaware business trust and is registered under the
Investment Company Act of 1940, as amended, as an open-end management investment
company.  The Trust consists of nine portfolios (the "Funds"): Growth and Income
Fund, CORE U.S. Equity Fund, CORE Large Cap Growth Fund, CORE Small Cap Equity
Fund, Capital Growth Fund, Mid Cap Equity Fund, International Equity Fund,
Global Income Fund and High Yield Fund.  The Global Income Fund is a non-
diversified Fund; all other Funds are diversified.

The only transaction of the Funds has been the initial sale on December 12, 1997
of 10,000 shares of the Growth and Income Fund to The Goldman Sachs Group, L.P.
Shares of each of the Funds will be offered to the separate accounts of
unaffiliated insurance companies.

The preparation of this financial statement requires management to make
estimates and assumptions that may affect the reported amounts.

NOTE 2.  ORGANIZATIONAL COSTS

     The Trust has incurred organizational expenses in connection with the
start-up and initial registration of the Funds.  The total estimated
organizational costs are $100,000 for the Trust.  Goldman, Sachs & Co. (the
"distributor") will seek reimbursement from the remaining Funds upon
commencement of operations.  Organizational costs will be amortized over 60
months on a straight-line basis beginning with the commencement of each of the
Fund's operations.  If any or all of the shares held by The Goldman Sachs Group,
L.P. representing initial capital of the Funds are redeemed during the
amortization period, the redemption proceeds will be reduced by the pro rata
portion of the unamortized organizational cost balance.

NOTE 3.  FEDERAL TAXES

     The Trust intends to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute each year
substantially all of the investment company taxable and tax-exempt income to the
shareholders of each of the Funds.  Accordingly, no federal tax provisions are
required.

NOTE 4.  AGREEMENTS

     The Funds have entered into a Management Agreement (the "Agreement") with
Goldman Sachs Asset Management ("GSAM"), a separate operating division of
Goldman, Sachs & Co. ("Goldman Sachs") and Goldman Sachs Asset Management
International ("GSAMI").  GSAM serves as the investment advisor to the Growth
and Income, CORE U.S. Equity, CORE Large Cap Growth, CORE Small Cap Equity,
Capital Growth, Mid Cap Equity and High Yield Funds.  GSAMI serves as investment
advisor to the International Equity and Global Income Funds.  Under the
Agreement, GSAM and GSAMI, subject to the general supervision of the Trust's
Board of Trustees, manage the Funds' portfolios.  As compensation for the
services rendered under the Agreement, the assumption of the expenses related
thereto and administering the Funds' business affairs, including providing
facilities, GSAM and GSAMI are entitled to a fee, computed daily and payable
monthly, at an annual rate equal to:

Growth and Income Fund                                            .75%

                                  APPENDIX A/1/

            DESCRIPTION OF BOND RATINGS, INCLUDING MUNICIPAL BONDS
                               

                        MOODY'S INVESTORS SERVICE, INC.

Bond Ratings
- ------------

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

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

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

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

/1/ The rating systems described herein are believed to be the most recent
ratings systems available from Moody's Investors Service, Inc. and Standard &
Poor's Ratings Group at the date of this Additional Statement for the securities
listed. Ratings are generally given to securities at the time of issuance. While
the rating agencies may from time to time revise such ratings, they undertake no
obligation to do so.

                                      A-1
<PAGE>
 
     BA:  Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well assured. Often the protection of
interest and principal payments may be very moderate and thereby not well
safeguarded during both good and bad times over the future.  Uncertainty of
position characterizes bonds in this class.

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

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

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

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

     UNRATED:  Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.

     Should no rating be assigned, the reason may be one of the following:

     1.   An application for rating was not received or accepted.

     2.   The issue or issuer belongs to a group of securities or companies that
          are not rated as a matter of policy.

     3.   There is a lack of essential data pertaining to the issue or issuer.

     4.   The issuer was privately placed, in which case the rating is not
          published in Moody's publications.

     Suspension or withdrawal may occur if new and material circumstances arise,
the effects of which preclude satisfactory analysis; if there is no longer
available reasonable up-to-date data to permit a judgment to be formed; if a
bond is called for redemption; or for other reasons.

       CON. (---):  Bonds for which the security depends upon the completion of
some act or the fulfillment of some condition are 

                                      A-2
<PAGE>
 
rated conditionally. These are bonds secured by (a) earnings of projects under
construction, (b) earnings of projects unseasoned in operation 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.

       (P)...:  When applied to forward delivery bonds, indicates that the
rating is provisional pending delivery of the bonds.  The rating may be revised
prior to delivery if changes occur in the legal documents or the underlying
credit quality of the bonds.

     NOTE:  Those bonds in the Aa, A, Baa, Ba and B groups which Moody's
believes possess the strongest investment attributes are designed by the symbols
Aa1, A1, Baa1 and B1.


Description of Ratings of Commercial Paper
- ------------------------------------------

     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.  Moody's commercial paper rating categories are as follows:

     PRIME-1:  Issuers rated Prime-1 (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 industries.

       -       High rates of return on funds employed.

       -       Conservative capitalization structures with moderate reliance on
               debt and ample asset protection.

       -       Broad margins in earnings coverage of fixed financial charges and
               high internal cash generation.

       -       Well established access to a range of financial markets and
               assured sources of alternate liquidity.

     PRIME-2:  Issuers rated Prime-2 (or supporting institutions) have a strong
     ability for repayment of short-term debt obligations. This will normally be
     evidenced by many of the 

                                      A-3
<PAGE>
 
     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 rated Prime-3 (or supporting institutions) have an
     acceptable ability for repayment of senior short-term 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.


Description of Ratings of State and Municipal Notes
- ---------------------------------------------------

     Moody's ratings for state and municipal short-term obligations will be
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.
Factors affecting the liquidity of the borrower and short-term cyclical elements
are critical in short-term  ratings, while other factors of major importance in
bond risk, long-term secular trends for example, may be less important over the
short run.  Symbols used will be as follows:

     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. Margins of protection
are ample although not so large as in the preceding group.

     MIG-3/VMIG-3:  This designation denotes favorable quality. All security
elements are accounted for but there is 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.

     MIG-4/VMIG-4:  This designation denotes adequate quality. Protection
commonly regarded as required of an investment security 

                                      A-4
<PAGE>
 
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 margins of protection.


                                 STANDARD & POOR'S RATINGS GROUP

Bond Ratings
- ------------

     AAA:  Bonds and debt rated AAA have the highest rating assigned by Standard
& Poor's.  Capacity to pay interest and repay principal is extremely strong.

     AA:  Bonds and debt rated AA have a very strong capacity to pay interest
and repay principal and differ from the higher rated issues only in small
degree.

     A:  Bonds and debt rated A have a very strong capacity to pay interest and
repay principal although they are somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than bonds in higher
rated categories.

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

     BB, B, CCC, CC, C:  Bonds and debt rated BB, B, CCC, CC and C are regarded,
on balance, as predominately speculative with respect to capacity to pay
interest and repay principal. BB indicates the least degree of speculation and C
the highest. While such bonds will likely have some quality and protective
characteristics, these are outweighed by large uncertainties of major risk
exposures to adverse conditions.

     BB:  Bonds and debt rated BB have less near-term vulnerability to default
than other speculative issues.  However, such securities face major ongoing
uncertainties or exposure to adverse business, financial, or economic conditions
which could lead to inadequate capacity to meet timely interest and principal
payments.  The BB rating category is also used for bonds that are subordinated
to senior debt assigned an actual or implied BBB- rating.

     B:  Bonds and debt rated B have a greater vulnerability to default but
currently have the capacity to meet interest payments 

                                      A-5
<PAGE>
 
and principal repayments. Adverse business, financial, or economic conditions
will likely impair capacity or willingness to pay interest and repay principal.

     The B rating category is also used for bonds that are subordinated to
senior debt assigned an actual or implied BB or BB- rating.

     CCC:  Bonds and debt rated CCC have currently identifiable vulnerability to
default, and are dependent upon favorable business, financial, and economic
conditions to meet timely payment of interest and repayment of principal.  In
the event of adverse business, financial, or economic conditions, such
securities are not likely to have the capacity to pay interest and repay
principal.

     The CCC rating category is also used for bonds that are subordinated to
senior debt assigned an actual or implied B or B- rating.

     CC:  The rating CC is typically applied to bonds and debt that are
subordinated to senior debt assigned an actual or implied CCC rating.

     C:  The rating C is typically applied to bonds and debt that are
subordinated to senior debt assigned an actual or implied CCC- debt rating.  The
C rating may be used to cover a situation where a bankruptcy petition has been
filed, but debt service payments are continued.

     C1:  The rating C1 is reserved for income bonds on which no interest is
being paid.

     D:  Bonds and debt rated D are in default and payment of interest and/or
repayment of principal is in arrears.  The D rating category is used when
interest payments or principal payments are not made on the date due even if the
applicable grace period has not expired, unless Standard & 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 if debt service payments are
jeopardized.

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

       R:  This rating is attached to highlight derivative, hybrid, and certain
other obligations that S & P believes may experience high volatility or high
variability in expected returns due to non-credit risks.  Examples of such
obligations are: 

                                      A-6
<PAGE>
 
securities whose principal or interest return is indexed to equities,
commodities, or currencies; certain swaps and options; and interest-only and
principal-only mortgage securities. The absence of an "r" symbol should not be
taken as an indication that an obligation will exhibit no volatility or
variability in total return.

     N.R.:  Not rated.

     Notes:  Bonds which are unrated expose the investor to risks with respect
to capacity to pay interest or repay principal which are similar to the risks of
lower-rated speculative obligations. The Fund is dependent on the Investment
Adviser's judgment, analysis and experience in the evaluation of such bonds.

     Investors should note that credit factors affecting high yield, fixed
income securities change quickly and the assignment of a rating to a particular
bond by a rating service may not reflect the effect of recent developments on
the issuer's ability to make interest and principal payments.


Description of Ratings of Commercial Paper
- ------------------------------------------

     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.  Standard & Poor's commercial paper rating categories are as follows:

     A-1:  This highest category indicates that the degree of safety regarding
timely payment is strong.  Those issues determined to possess extremely strong
safety characteristics are denoted with a plus sign (+) designation.

     A-2:  Capacity for timely payment on issues with this designation is
satisfactory.  However, the relative degree of safety is not as high as for
issues designated A-1.

     A-3:  Issued carrying this designation have adequate capacity for timely
payment.  They are, however, more vulnerable to the adverse effects of changes
in circumstances than obligations carrying the higher designations.

     B:  Issues rated B are regarded as having only speculative capacity for
timely payment.

     C:  This rating is assigned to short-term debt obligations with a doubtful
capacity for payment.

                                      A-7
<PAGE>
 
     D:  Debt rated D is in payment default.  The D rating category is used when
interest payments or principal payments are not made on the date due, even if
the applicable grace period has not expired, unless S&P believes such payments
will be made during such grace period.


Description of Ratings of Municipal Notes
- -----------------------------------------

     A Standard & Poor's note rating reflects the liquidity concerns and market
access risks unique to notes.  Notes due in three years or less will likely
receive a note rating.  Notes maturing beyond three years will most likely
receive a long-term debt rating. The following criteria will be used in making
that assessment.

 -   Amortization schedule (the larger the final maturity relative to other
     maturities the more likely it will be treated as a note).

 -   Source of payment (the more dependent the issue is on the market for its
     refinancing, the more likely it will be treated as a note).

Note rating symbols are as follows:

SP-1:            Very strong or strong capacity to pay principal and interest.
       Those issues determined to possess overwhelming safety characteristics
       will be given a plus (+) designation.

SP-2:            Satisfactory capacity to pay principal and interest with some
       vulnerability to adverse financial and economic changes over the term of
       the notes.

SP-3:          Speculative capacity to pay principal and interest.


                            FITCH IBCA, Inc. 

Long-Term Debt and Preferred Stock
- ----------------------------------

     The ratings represent Fitch's assessment of the issuer's ability to meet
the obligations of a specific debt issue or class of debt.  The ratings take
into consideration special features of the issue, its relationship to other
obligations of the issuer, the current financial condition and operative
performance of the issuer and of any guarantor, as well as the political and
economic environment that might affect the issuer's future financial strength
and credit quality.

                                      A-8
<PAGE>
 
     AAA:  Bonds rated AAA are considered to be investment grade and of the
highest credit quality.  The obligor has an exceptionally strong ability to pay
interest and repay principal, which is unlikely to be affected by reasonably
foreseeable events.

     AA:  Bonds rated AA are considered to be investment grade and of very high
credit quality.  The obligor's ability to pay interest and repay principal is
very strong, although not quite as strong as bonds rated AAA.  Because bonds
rated in the AAA and AA categories are not significantly vulnerable to
foreseeable future developments, short-term debt of these issuers is generally
rated F-1+.

     A:  Bonds rated A are considered to be investment grade and of high credit
quality. The obligor's ability to pay interest and repay principal is considered
to be strong, but may be more vulnerable to adverse changes in economic
conditions and circumstances than bonds with higher ratings.

     BBB:  Bonds rated BBB are considered to be investment grade and of
satisfactory credit quality.  The obligor's ability to pay interest and repay
principal is considered to be adequate. Adverse changes in economic conditions
and circumstances, however, are more likely to have an adverse impact on these
bonds and, therefore, impair timely payment.  The likelihood that the ratings of
these bonds will fall below investment grade is higher than for bonds with
higher ratings.

     BB:  Bonds are considered speculative.  The obligor's ability to pay
interest and repay principal may be affected over time by adverse economic
changes.  However, business and financial alternatives can be identified, which
could assist the obligor in satisfying its debt service requirements.

     B:  Bonds are considered highly speculative.  While bonds in this class are
currently meeting debt service requirements, the probability of continued timely
payment of principal and interest reflects the obligor's limited margin of
safety and the need for reasonable business and economic activity throughout the
life of the issue.

     CCC:  Bonds have certain identifiable characteristics that, if not
remedied, may lead to default.  The ability to meet obligations requires an
advantageous business and economic environment.

     CC:  Bonds are minimally protected.  Default in payment of interest and/or
principal seems probable over time.

                                      A-9
<PAGE>
 
     C:  Bonds are in imminent default in payment of interest or principal.

     DDD, DD, AND D:  Bonds are in default on interest and/or principal
payments.  Such bonds are extremely speculative and should be valued on the
basis of their ultimate recovery value in liquidation or reorganization of the
obligor. DDD represents the highest potential for recovery on these bonds, and D
represents the lowest potential for recovery.

     PLUS (+) AND MINUS (-) signs are used with a rating symbol to indicate the
relative position of a credit within the rating category. Plus and minus signs,
however, are not used in the AAA, DDD, DD, or D Categories.

Short-Term Ratings
- ------------------

     Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of up to three years, including commercial
paper, certificates of deposit, medium-term notes, and municipal and investment
notes.

F-1+:            Exceptionally Strong Credit Quality.  Issues assigned this
       rating are regarded as having the strongest degree of assurance for
       timely payment.

F-1:   Very Strong Credit Quality.  Issues assigned this rating reflect an
       assurance of timely payment only slightly less in degree than issues
       rated F-1+.

F-2:   Good Credit Quality.  Issues assigned this rating have a satisfactory
       degree of assurance for timely payment, but the margin of safety is not
       as great as for issues assigned F-1+ and F-1 ratings.

F-3:   Fair Credit Quality.  Issues assigned this rating have characteristics
       suggesting that the degree of assurance for timely payment is adequate;
       however, near-term adverse changes could cause these securities to be
       rated below investment grade.

F-S:   Weak Credit Quality.  Issues assigned this rating have characteristics
       suggesting a minimal degree of assurance for timely payment and are
       vulnerable to near-term adverse changes in financial and economic
       conditions.

D:     Default.  Issues assigned this rating are in actual or imminent payment
       default.

                                      A-10
<PAGE>
 
LOC:   The symbol LOC indicates that the rating is based on a letter of credit
       issued by a commercial bank.

                                 DUFF & PHELPS
                                 -------------

Long-Term Debt and Preferred Stock
- ----------------------------------

     AAA:  Highest credit quality.  The risk factors are negligible, being only
slightly more than for risk-free U.S. Treasury debt.

     AA+, AA, AA-:  High credit quality. Protection factors are strong.  Risk is
modest but may vary slightly from time to time because of economic conditions.

     A+, A, A-:  Protection factors are average but adequate. However, risk
factors are more variable and greater in periods of economic stress.

     BBB+, BBB, BBB-:  Below average protection factors but still considered
sufficient for prudent investment.  Considerable variability in risk during
economic cycles.

     BB+, BB, BB-:  Below investment grade but deemed likely to meet obligations
when due.  Present or prospective financial protection factors fluctuate
according to industry conditions or company fortunes.  Overall quality may move
up or down frequently within this category.

     B+, B, B-:  Below investment grade and possessing risk that obligations
will not be met when due.  Financial protection factors will fluctuate widely
according to economic cycles, industry conditions and/or company fortunes.
Potential exists for frequent changes in the rating within this category or into
a higher or lower rating grade.

     CCC:  Well below investment grade securities.  Considerable uncertainty
exists as to timely payment of principal, interest or preferred dividends.
Protection factors are narrow and risk can be substantial with unfavorable
economic/industry conditions, and/or with unfavorable company developments.

     DD:  Defaulted debt obligations.  Issuer failed to meet scheduled principal
and/or interest payment.

     DP:  Represents preferred stock with dividend arrearages.

                                      A-11
<PAGE>
 
Commercial Paper/Certificates of Deposits
- -----------------------------------------

DUFF 1 PLUS:        Highest certainty of timely payment.  Short-term liquidity
                    including internal operating factors and/or ready access to
                    alternative sources of funds, is clearly outstanding, and
                    safety is just below risk-free U.S.  Treasury short-term
                    obligations.

DUFF 1:             Very high certainty of timely payment.  Liquidity factors
                    are excellent and supported by strong fundamental protection
                    factors.  Risk factors are minor.

DUFF 1 MINUS:       High certainty of timely payment.  Liquidity factors are
                    strong and supported by good fundamental protection factors.
                    Risk factors are very small.

DUFF 2:             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.

DUFF 3:             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.

DUFF 4:             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.

DUFF 5:             Issuer failed to meet scheduled principal and/or interest
                    payments.

Notes: Bonds which are unrated may expose the investor to risks with respect to
       capacity to pay interest or repay principal which are similar to the
       risks of lower-rated bonds.  The Fund is dependent on the Investment
       Adviser's judgment, analysis and experience in the evaluation of such
       bonds.
