NEW PACIFIC FUND
 
INVESTMENT OBJECTIVE AND PRINCIPAL INVESTMENT STRATEGIES
The fund's investment objective is long-term growth of capital.
 
The fund seeks to achieve its objective by normally investing at least 65% of
its total assets in the securities of companies domiciled in the following
countries: Australia, Hong Kong, India, Indonesia, Malaysia, New Zealand,
Pakistan, the Philippines, Singapore, South Korea, Taiwan, and Thailand. These
countries are designated as the fund's primary investment area and the list of
countries may be revised with the approval of the fund's Board of Trustees. The
fund considers a company to be domiciled in a particular country if it (i) is
organized under the laws of a particular country and has a principal office in a
particular country; or (ii) derives 50% or more of its total revenues from
business in that country provided that, in the view of the fund's portfolio
managers, the value of the issuers' securities tend to reflect such country's
development to a greater extent than developments elsewhere.
 
The fund may invest up to 35% of its total assets in equity securities of
issuers domiciled outside of its primary investment area. The fund may also
invest up to 35% of its total assets in investment-grade debt securities, or
securities deemed by the fund's subadvisor to be of comparable quality. These
debt securities could include U.S. and foreign government securities and
corporate debt securities.
 
In selecting investments, the portfolio managers seek to identify those
countries and industries where political and economic factors, including
currency movements, are likely to produce above-average growth rates. The
portfolio managers balance the potential benefits with the risks of investing in
those countries and industries. The portfolio managers usually sell a particular
security when any of those factors materially changes.
 
In anticipation of or in response to adverse market conditions or for cash
management purposes, the fund may hold all or a portion of its assets in cash
(U.S. dollars, foreign currencies or multinational currency units), money market
instruments, or high quality debt securities. As a result, the fund may not
achieve its investment objective.
 
PRINCIPAL RISKS OF INVESTING IN THE FUND
There is a risk that you could lose all or a portion of your investment in the
fund. The value of your investment in the fund will go up and down with the
prices of the securities in which the fund invest. The prices of equity
securities change in response to many factors, including the historical and
prospective earnings of the issuer, the value of its assets, general economic
conditions, interest rates, investor perceptions, and market liquidity.
 
The value of the fund's shares is particularly vulnerable to factors affecting
Pacific region countries, such as substantial economic or regulatory changes.
Because the fund focuses its investments in Pacific region countries, the value
of your shares may rise and fall more than the value of shares of a fund that
invests more broadly.
 
The prices of foreign securities may be further affected by other factors
including:
 
CURRENCY EXCHANGE RATES -- The dollar value of the fund's foreign investments
will be affected by changes in the exchange rates between the dollar and the
currencies in which those investments are traded.
 
POLITICAL AND ECONOMIC CONDITIONS -- The value of the fund's foreign investments
may be adversely affected by political and social instability in their home
countries and by changes in economic or taxation policies in those countries.
 
REGULATIONS -- Foreign companies generally are subject to less stringent
regulations, including financial and accounting controls, than are U.S.
companies. As a result, there generally is less publicly available information
about foreign companies than about U.S. companies.
 
MARKETS -- The securities markets of other countries are smaller than U.S.
securities markets. As a result, many foreign securities may be less liquid and
more volatile than U.S. securities.
 
                               Prospectus Page 3
<PAGE>
To the extent that the fund invests in securities of issuers in emerging
markets, the factors listed above may have a greater effect on the fund.
 
The value of your shares could be adversely affected if the computer systems
used by the fund's investment advisor and the fund's other service providers are
unable to distinguish the year 2000 from the year 1900.
 
The fund's investment advisor and independent technology consultants are working
to avoid year 2000-related problems in the advisor's systems and to obtain
assurances that other service providers are taking similar steps. Year 2000
problems may also affect issuers in whose securities the fund invests.
 
An investment in the fund is not a deposit of a bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.
 
PERFORMANCE INFORMATION
The bar chart and table shown below provide an indication of the risks of
investing in the fund. The fund is offered exclusively for investment in
separate accounts that fund certain variable annuity contracts offered by

and fees associated with those separate accounts. Those charges and fees will
reduce returns. The fund's past performance is not necessarily an indication of
its future performance.

EUROPE FUND
 
INVESTMENT OBJECTIVE AND STRATEGIES
The fund's investment objective is long-term growth of capital.
 
The fund seeks to achieve its objective by normally investing at least 65% of
its total assets in equity securities of companies domiciled in eighteen
countries located in Europe. These countries are designated as the fund's
primary investment area and the list of countries may be revised with the
approval of the fund's Board of Trustees. The fund considers a company to be
domiciled in a particular country if it (i) is organized under the laws of a
particular country and has a principal office in a particular country; or (ii)
derives 50% or more of its total revenues from business in that country provided
that, in the view of the fund's portfolio managers, the value of the issuers'
securities tend to reflect such country's development to a greater extent than
developments elsewhere.
 
The fund may invest up to 35% of its total assets in equity securities of
issuers domiciled outside of its primary investment area. The fund may also
invest up to 35% of its total assets in U.S. and foreign investment-grade debt
securities, or securities deemed by the fund's subadvisor to be of comparable
quality. These debt securities could include U.S. and foreign government
securities and corporate debt securities.
 
In selecting investments, the portfolio managers seek to identify those

(U.S. dollars, foreign currencies or multinational currency units), money market
instruments, or high quality debt securities. As a result, the fund may not
achieve its investment objective.
 
PRINCIPAL RISKS OF INVESTING IN THE FUND
There is a risk that you could lose all or a portion of your investment in the

prices of the securities in which the fund invests. The prices of equity
securities change in response to many factors, including the historical and
prospective earnings of the issuer, the value of its assets, general economic
conditions, interest rates, investor perceptions, and market liquidity.
 
Because fund focuses its investments in European countries, the value of your
shares may rise and fall more than the value of shares of a fund that invests in
a broader geographic region.
The prices of securities of foreign issuers may be further affected by other
factors, including:
 
CURRENCY EXCHANGE RATES -- The dollar value of the fund's foreign investments
will be affected by changes in the exchange rates between the dollar and the
currencies in which those investments are traded.

INTERNATIONAL FUND
 
INVESTMENT OBJECTIVE AND STRATEGIES
The fund's investment objective is long-term growth of capital.
 
The fund seeks to achieve its objective by normally investing at least 65% of
its total assets in the securities of companies domiciled in the following
countries: Argentina, Australia, Austria, Belgium, Brazil, Canada, Chile,
Colombia, Denmark, Finland, France, Germany, Greece, Hong Kong, India,
Indonesia, Ireland, Israel, Italy, Japan, Luxembourg, Malaysia, Mexico, the
Netherlands, New Zealand, Norway, Pakistan, Peru, the Philippines, Portugal,
Singapore, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey,
the United Kingdom, and Venezuela. These countries are designated as the fund's
primary investment area and the list of countries may be revised with the
approval of the fund's Board of Trustees. The fund considers a company to be
domiciled in a particular country if it (i) is organized under the laws of a
particular country and has a principal office in a particular country; or (ii)
derives 50% or more of its total revenues from business in that country provided
that, in the view of the fund's portfolio managers, the value of the issuers'
securities tend to reflect such country's development to a greater extent than
developments elsewhere.
 
The fund may invest up to 35% of its total assets in equity securities of
companies domiciled outside its primary investment area and in U.S. and foreign
investment grade debt securities.
 
In selecting investments, the portfolio managers seek to identify those
countries and industries where political and economic factors, including
currency movements, are likely to produce above-average growth rates. The
portfolio managers balance the potential benefits with the risks of investing in
those countries and industries. The portfolio managers usually sell a particular
security when any of those factors materially changes.
 
In anticipation of or in response to adverse market conditions or for cash
management purposes, the fund may hold cash or invest all or a portion of its
assets in cash (U.S. dollars, foreign currencies or multinational currency
units), money market instruments, or high quality debt securities. Such holdings
would not help the fund achieve its investment objective.
 
The fund may engage in active and frequent trading of portfolio securities to
achieve its investment objective. If it does trade in this way, it may incur
increased transaction costs, which can lower the actual return on your
investment. Active trading may also increase short-term capital gains and
losses, which may affect the taxes you have to pay.

There is a risk that you could lose all or a portion of your investment in the
fund. The value of your investment in the fund will go up and down with the
prices of the securities in which the fund invests. The prices of equity
securities change in response to many factors, including the historical and
prospective earnings of the issuer of the stock, the value of its assets,
general economic conditions, interest rates, investor perceptions, and market
liquidity.
 
In addition, the prices of securities of foreign issuers may be further affected
by other factors including:
 
CURRENCY EXCHANGE RATES -- The dollar value of the fund's foreign investments
will be affected by changes in the exchange rates between the dollar and the
currencies in which those investments are traded.
 
POLITICAL AND ECONOMIC CONDITIONS -- The value of the fund's foreign investments
may be adversely affected by political and social instability in their home
countries and by changes in economic or taxation policies in those countries.
 
REGULATIONS -- Foreign companies generally are subject to less stringent
regulations, including financial and accounting controls, than are U.S.
companies. As a result, there generally is less publicly available information
about foreign companies than about U.S. companies.
 
MARKETS -- The securities markets of some foreign countries are smaller and less
developed than U.S. securities markets. As a result, many foreign securities may
be less liquid and more volatile than U.S. securities.
 
To the extent that the fund invests in securities of issuers in emerging
markets, the factors listed above may have a greater effect on the fund.
 
The value of your shares could be adversely affected if the computer systems
used by the fund's investment advisor and the fund's other service providers are
unable to distinguish the year 2000 from the year 1900.
 
The fund's investment advisor and independent technology consultants are working
to avoid year 2000-related problems in the advisor's systems and to obtain
assurances that other service providers are taking similar steps. Year 2000
problems may also affect issuers in whose securities the fund invests.
 
An investment in the fund is not a deposit of a bank and is not insured or
guaranteed by the Federal

AMERICA FUND
 
INVESTMENT OBJECTIVE AND STRATEGIES
The fund's investment objective is long-term growth of capital.
 
The fund seeks to achieve its objective by normally investing at least 65% of
its total assets in the equity securities of mid-cap U.S. companies. The fund
considers a "mid-cap U.S. company" to be a U.S. corporation with a market
capitalization of between one and five billion dollars.
 
The fund may invest up to 35% of its total assets in equity securities of other
U.S. issuers and of foreign issuers in the form of American Depositary Receipts
or other securities convertible into the securities of foreign issuers. The fund
may also invest up to 35% of its total assets in investment-grade debt
securities of U.S. and foreign issuers. These debt securities could include U.S.
and foreign government securities and corporate debt securities.
 
In selecting investments, AIM seeks to identify companies that possess
sustainable above-average growth at an attractive offering price. First, the
portfolio managers track individual companies and categorize them into industry
groups. Securities are then bought and sold based upon ratings established by
the portfolio managers on a weekly basis. Securities ranked in the top 30% are
buys, and the bottom 30% are sells.
 
In anticipation of or in response to adverse market conditions or for cash
management purposes, the fund may hold all or a portion of its assets in cash
(U.S. dollars, foreign currencies or multinational currency units), money market
instruments, or high quality debt securities. As a result, the fund may not
achieve its investment objective.
 
The fund may engage in active and frequent trading of portfolio securities to
achieve its investment objective. If the fund does trade in this way, it may
incur increased transaction costs, which can lower the actual return on your
investment. Active trading may also increase short-term capital gains and
losses, which may affect the taxes you have to pay.
 
PRINCIPAL RISKS OF INVESTING IN THE FUND

INFRASTRUCTURE FUND
 
INVESTMENT OBJECTIVE AND STRATEGIES
The fund's investment objective is long-term capital growth.
 
The fund seeks to achieve its objective by normally investing at least 65% of
its total assets in equity securities of domestic and foreign infrastructure
companies. The fund considers an "infrastructure company" to be one that: (i)
derives at least 50% of its revenues or earnings from infrastructure activities;
or (ii) devotes at least 50% of its assets to such activities, based on its most
recent fiscal year. Such companies include those that design, develop, or
provide products and services significant to a country's infrastructure (such as
transportation systems, communications equipment and services, nuclear power and
other energy sources, water supply, and oil, gas and coal exploration).
 
The fund will normally invest in the securities of companies located in at least
three different countries, including the United States, and may invest a
significant portion of its assets in the securities of U.S. issuers. However,
the fund will invest no more than 50% of its total assets in the securities of
issuers in any one country, other than the U.S. The fund may invest
substantially in securities denominated in one or more currencies. The portfolio
may invest in companies located in developing countries, i.e., those that are in
the initial stages of their industrial cycles. The fund may also invest up to
20% of its total assets in lower-quality debt securities, i.e., "junk bonds."
 
The portfolio manager allocates the fund's assets among securities of countries
and in currency denominations that are expected to provide the best
opportunities for meeting the fund's investment objective. In analyzing specific
companies for possible investment, the portfolio manager ordinarily looks for
several of the following characteristics: above-average per share earnings
growth; high return on invested capital; a healthy balance sheet; sound
financial and accounting policies and overall financial strength; strong
competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets. The
portfolio manager usually sells a particular security when any of those factors
materially changes.
 
In anticipation of or in response to adverse market conditions or for cash
management purposes, the fund may hold all or a portion of its assets in cash
(U.S. dollars, foreign currencies or multinational currency units), money market
instruments, or high quality debt securities. As a result, the fund may not
achieve its investment objective.
 
PRINCIPAL RISKS OF INVESTING IN THE FUND
There is a risk that you could lose all or a portion of your investment in the
fund. The value of your investment in the fund will go up and down with the
prices of the securities in which the fund invests. The prices of equity
securities change in response to many factors, including the historical and
prospective earnings of the issuer of the stock, the value of its assets,
general economic conditions, interest rates, investor perceptions, and market
liquidity.
 
The value of the fund's shares is particularly vulnerable to factors affecting
infrastructure industry, such as substantial political, environmental, and other
governmental regulation. Such regulation may, among other things, increase
compliance costs and proscribe the development of new technologies. In addition,
increases in fuel, energy, and other prices have historically limited the growth
potential of infrastructure companies.
 
Because the fund focuses its investments in the infrastructure industries, the
value of your shares may rise and fall more than the value of shares of a fund
that invests more broadly.
 
The prices of foreign securities may be further affected by other factors,
including:
 
CURRENCY EXCHANGE RATES -- The dollar value of the fund's foreign investments
will be affected by changes in the exchange rates between the dollar and the
currencies in which those investments are traded.
 
POLITICAL AND ECONOMIC CONDITIONS -- The value of the fund's foreign investments
may be adversely affected by political and social instability in their home
countries and by changes in economic or taxation policies in those countries.
 
REGULATIONS -- Foreign companies generally are subject to less stringent
regulations, including financial and accounting controls, than are U.S.
companies. As a result, there generally is less publicly available information
about foreign companies than about U.S. companies.
 
MARKETS -- The securities markets of other countries are smaller than U.S.
securities markets. As a result, many foreign securities may be less liquid and
their prices may be more volatile than U.S. securities.
 
These factors may affect the prices of common stocks issued by foreign companies
located in developing countries more than those in countries with
 
                               Prospectus Page 11
<PAGE>
mature economies. For example, many developing countries have, in the past,
experienced high rates of inflation or sharply devalued their currencies against
the U.S. dollar, thereby causing the value of investments in companies located
in those countries to decline. Transaction costs are often higher in developing
countries and there may be delays in settlement procedures.
 
The value of your shares could be adversely affected if the computer systems
used by the fund's investment advisor and the fund's other service providers are
unable to distinguish the year 2000 from the year 1900.
 
The fund's investment advisor and independent technology consultants are working
to avoid year 2000-related problems in the advisor's systems and to obtain
assurances that other service providers are taking similar steps. Year 2000
problems may also affect issuers in whose securities the fund invests.
 
An investment in the fund is not a deposit of a bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.

NATURAL RESOURCES FUND
 
INVESTMENT OBJECTIVE AND STRATEGIES
The fund's investment objective is long-term capital growth.
 
The fund seeks to achieve its objective by normally investing at least 65% of
its total assets in equity securities of domestic and foreign natural resources
companies. The fund considers a "natural resources" company to be one that (i)
derives at least 50% of its revenues or earnings from natural resource
activities, or (ii) devotes at least 50% of its assets to such activities, based
on its most recent fiscal year. Such companies include those that own, explore,
or develop natural resources (such as oil, metals, forest products, and
chemicals) and other basic commodities (such as foodstuffs) or supply goods and
services to such companies.
 
The fund will normally invest in the securities of issuers located in at least
three different countries, including the United States. However, the fund will
invest no more than 50% of its total assets in the securities of issuers in any
one country, other than the U.S. The fund may invest in companies located in
developing countries, i.e., those that are in the initial stages of their
industrial cycles. The fund may invest substantially in securities denominated
in one or more currencies. The fund may invest up to 20% of its total assets in
lower-quality debt securities, i.e., "junk bonds."
 
The portfolio manager allocates the fund's assets among securities of companies
in these natural resource industries and commodity groups that are expected to
provide the best opportunities during periods of rising inflation. In analyzing
specific companies for possible investment, the portfolio manager ordinarily
looks for several of the following characteristics: above-average per share
earnings growth; high return on invested capital; a healthy balance sheet; sound
financial and accounting policies and overall financial strength; strong
competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets. The
portfolio manager usually sells a particular security when any of those factors

management purposes, the fund may hold all or a portion of its assets in cash
(U.S. dollars, foreign currencies or multinational currency units), money market
instruments, or high quality debt securities. As a result, the fund may not
achieve its investment objective.
 
The fund may engage in active and frequent trading of portfolio securities to
achieve its investment objective. If the fund does trade in this way, it may
incur increased transaction costs and brokerage commissions, both of which can
lower the actual return on your investment. Active trading may also increase
short-term capital gains and losses, which may affect the taxes you have to pay.

There is a risk that you could lose all or a portion of your investment in the

securities change in response to many factors, including the historical and
prospective earnings of the issuer of the stock, the value of its assets,
general economic conditions, interest rates, investor perceptions, and market
liquidity.
 
The value of the fund's shares is particularly vulnerable to factors affecting
natural resources industry, such as increasing regulation of the environment by
both U.S and foreign governments. Increased environmental regulation may, among
other things, increase compliance costs and affect business opportunities for
the companies in which the fund invests. Fund share value may also be affected
by changing commodity prices, which can be highly volatile and are subject to
the risks of oversupply and reduced demand.
 
Because the fund focuses its investments in the natural resources industries,
the value of your shares may rise and fall more than the value of shares of a
fund that invests more broadly.

their prices may be more volatile than U.S. securities.
 
These factors may affect the prices of common stocks issued by foreign companies
located in developing countries more than those in countries with mature
economies. For example, many developing countries have, in the past, experienced
high rates of inflation or sharply devalued their currencies against the U.S.
dollar, thereby causing the value of investments in companies located in those
countries to decline. Transaction costs are often

higher in developing countries and there may be delays in settlement procedures.
 
The value of your shares could be adversely affected if the computer systems
used by the fund's investment advisor and the fund's other service providers are
unable to distinguish the year 2000 from the year 1900.
 
The fund's investment advisor and independent technology consultants are working
to avoid year 2000-related problems in the advisor's systems and to obtain
assurances that other service providers are taking similar steps. Year 2000
problems may also affect issuers in whose securities the fund invests.
 
An investment in the fund is not a deposit of a bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.

LATIN AMERICA FUND
 
INVESTMENT OBJECTIVES AND STRATEGIES
The fund's investment objective is capital appreciation.
 
The fund seeks to achieve its objective by investing at least 65% of its total
assets in equity and debt securities of Latin American issuers. The fund
considers securities of "Latin American issuers" to include: (1) securities of
companies organized under the laws of, or having a principal office located in,
a Latin American country; (2) securities of companies that derive 50% or more of
their total revenues from business in Latin America, provided that, in the view
of the sub-advisor, the value of such issuer's securities reflect Latin American
developments to a greater extent than developments elsewhere; (3) securities
issued or guaranteed by the government of a country in Latin America, its
agencies or instrumentalities, or municipalities, or the central bank of such
country; (4) U.S. dollar denominated securities or securities denominated in a
Latin American currency issued by companies to finance operations in Latin
America; and (v) securities of Latin American issuers in the form of depository
shares. The fund considers Latin America to include Mexico and the countries
within Central and South America and the Caribbean many of which are considered
developing countries, i.e., those that are in the initial stages of their
industrial cycles.
 
The fund will normally invest a majority of its assets in equity securities. The
fund may also invest up to 50% of its total assets in debt securities, which may
consist of lower-quality debt securities, e.g., "junk bonds" and "Brady Bonds."
Brady Bonds are debt restructurings that provide for the exchange of cash and
loans for newly-issued bonds. The fund currently expects to invest primarily in
securities issued by companies and governments in Mexico, Chile, Brazil and
Argentina. The fund may invest more than 25% of its total assets in any of these
four countries but expects to invest no more than 60% of its total assets in any
one country. The fund may invest up to 35% of its total assets in a combination
of equity and debt securities of U.S. issuers.
 
In allocating investments among the various Latin American countries, the
portfolio manager looks principally at the stage of industrialization, potential
for productivity gains through economic deregulation, the impact of financial
liberalization, and monetary conditions and the political outlook in each
country. Further, the portfolio manager selects between debt and equity
investments based on additional economic criteria such as fundamental economic
strength, expected corporate profits, the condition of balance of payments,
changes in the terms of trade, and currency and interest rate trends. The
portfolio manager usually sells a particular security when any of those factors
materially changes.
 
The fund is a non-diversified portfolio. This means that it may invest more than
5% of its assets in the securities of any one issuer, with respect to 50% of its
assets.
 
In anticipation of or in response to adverse market conditions or for cash
management purposes, the fund may hold all or a portion of its assets in cash
(U.S. dollars, foreign currencies or multinational currency units), money market
instruments, or high quality debt securities. As a result, the fund may not
achieve its investment objective.
 
PRINCIPAL RISKS OF INVESTING IN THE FUND
There is a risk that you could lose all or a portion of your investment in the
fund. The value of your investment in the fund will go up and down with the
prices of the securities in which the fund invests. The prices of equity
securities change in response to many factors, including the historical and
prospective earnings of the issuer of the stock, the value of its assets,
general economic conditions, interest rates, investor perceptions, and market
liquidity. Debt securities are particularly vulnerable to credit risk and
interest rate fluctuations. When interest rates rise, bond prices fall; the
longer the bond's duration, the more sensitive it is to this risk.
 
Because fund focuses its investments in Latin America, the value of your shares
may rise and fall more than the value of shares of a fund that invests in a
broader geographic region. In addition, the prices of securities of Latin
America issuers may be further affected by other factors, including:
 
CURRENCY EXCHANGE RATES -- The dollar value of the fund's foreign investments
will be affected by changes in the exchange rates between the dollar and the
currencies in which those investments are traded.
 
POLITICAL AND ECONOMIC CONDITIONS -- The value of the fund's foreign investments
may be adversely affected by political and social instability in their home
countries and by changes in economic or taxation policies in those countries.
 
REGULATIONS -- Foreign companies generally are subject to less stringent
regulations, including financial and accounting controls, than are U.S.
 
                               Prospectus Page 17
<PAGE>
companies. As a result, there generally is less publicly available information
about foreign companies than about U.S. companies.
 
MARKETS -- The securities markets of other countries are smaller than U.S.
securities markets. As a result, many foreign securities may be less liquid and
their prices may be more volatile than U.S. securities.
 
These factors may affect the price of securities issued by Latin American
companies located in developing countries more than those in countries with
mature economies. For example, many developing countries in Latin America have,
in the past, experienced high rates of inflation or sharply devalued their
currencies against the U.S. dollar, thereby causing the value of investments in
companies located in those countries to decline. Transaction costs are often
higher in developing countries and there may be delays in settlement procedures.
 
Because it is non-diversified, the fund may invest in fewer issuers than if it
was a diversified fund. Thus, the value of the fund's shares may vary more
widely, and the fund to be subject to greater investment and credit risk, than
if it invested more broadly.
 
Compared to higher-quality debt securities, junk bonds involve greater risk of
default or prices due to changes in the credit quality of the issuer because
they are generally unsecured and may be subordinated to other creditor's claims.
The value of lower quality debt securities often fluctuates in response to
company, political, or economic developments and can decline significantly over
short periods of time or during periods of general or regional economic
difficulty. Under some political, diplomatic, social, or economic circumstances,
some Latin American countries that issue lower-quality debt securities may be
unable or unwilling to make principal or interest repayments as they come due.
 
The value of your shares could be adversely affected if the computer systems
used by the fund's investment advisor and the fund's other service providers are
unable to distinguish the year 2000 from the year 1900.
 
The fund's investment advisor and independent technology consultants are working
to avoid year 2000-related problems in the advisor's systems and to obtain
assurances that other service providers are taking similar steps. Year 2000
problems may also affect issuers in whose securities the fund invests.
An investment in the fund is not a deposit of a bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.

EMERGING MARKETS FUND
 
INVESTMENT OBJECTIVES AND STRATEGIES
The fund's investment objective is long-term growth of capital.
 
The fund seeks to achieve its objective by investing at least 65% of its total
assets in equity securities of companies in emerging markets, which consist of
all countries determined by the portfolio managers to be developing or emerging
economies and markets, generally including every country in the world except the
United States, Canada, Japan, Australia, New Zealand, and most countries located
in Western Europe. Many of these countries are considered developing countries,
i.e., those that are in the initial stages of their industrial cycles.
 
The fund normally invests a majority of its assets in equity securities. The
fund may invest up to 20% of its total assets in high-yield debt securities
rated below investment grade, i.e., "junk bonds." The fund ordinarily will be
invested in the securities of issuers in at least three different emerging
markets countries.
 
In selecting countries in which to invest, the portfolio managers look
principally for strongly developing economies and increasingly sophisticated
markets. Within these countries, the portfolio managers ordinarily look for
economic and political factors, including currency movements, that are likely to
produce above-average growth rates. In analyzing specific companies for possible
investment, the portfolio managers invest in those companies that are best
positioned and managed to take advantage of these economic and political
factors. In evaluating investments in companies in developed markets, the
portfolio managers consider, among other things, the business activities of the
company in emerging markets and the impact that developments in emerging markets
are likely to have on the company. The portfolio managers usually sell a
particular security when any of those factors materially changes.
 
In anticipation of or in response to adverse market conditions or for cash
management purposes, the fund may hold all or a portion of its assets in cash
(U.S. dollars, foreign currencies or multinational currency units), money market
instruments, or high quality debt securities. As a result, the fund may not
achieve its investment objective.
 
The fund may engage in active and frequent trading to achieve its investment
objective. If the fund does trade in this way, it may incur increased
transaction costs and brokerage commissions, both of which can lower the actual
return on your investment.
 
PRINCIPAL RISKS OF INVESTING IN THE FUND
There is a risk that you could lose all or a portion of your investment in the
fund. The value of your investment in the fund will go up and down with the
prices of the securities in which the fund invests. The prices of equity
securities change in response to many factors, including the historical and
prospective earnings of the issuer of the stock, the value of its assets,
general economic conditions, interest rates, investor perceptions, and market
liquidity. Debt securities are particularly vulnerable to credit risk and
interest rate fluctuations. When interest rates rise, bond prices fall; the
longer the bond's duration, the more sensitive it is to this risk.
 
The prices of foreign securities may be further affected by other factors,
including:
 
CURRENCY EXCHANGE RATES -- The dollar value of the fund's foreign investments
will be affected by changes in the exchange rates between the dollar and the
currencies in which those investments are traded.
 
POLITICAL AND ECONOMIC CONDITIONS -- The value of the fund's foreign investments
may be adversely affected by political and social instability in their home
countries and by changes in economic or taxation policies in those countries.
 
REGULATIONS -- Foreign companies generally are subject to less stringent
regulations, including financial and accounting controls, than are U.S.
companies. As a result, there generally is less publicly available information
about foreign companies than about U.S. companies.
 
MARKETS -- The securities markets of other countries are smaller than U.S.
securities markets. As a result, many foreign securities may be less liquid and
their prices may be more volatile than U.S. securities.
 
These factors may affect the price of common stocks issued by foreign companies
located in developing countries more than those in countries with mature
economies. For example, many developing countries have, in the past, experienced
high rates of inflation or sharply devalued their currencies against the U.S.
dollar, thereby causing the value of investments in companies located in those
countries to decline. Transaction costs are often higher in developing countries
and there may be delays in settlement procedures.

Sovereign debt securities of developing country governments are generally
lower-quality debt securities. Sovereign debt securities are subject to the
additional risk that, under some political, diplomatic, social, or economic
circumstances, some developing countries that issue lower quality debt
securities may be unable or unwilling to make principal or interest payments as
they come due.
 
Compared to higher-quality debt securities, junk bonds involve greater risk of
default or prices due to changes in the credit quality of the issuer because
they are generally unsecured and may be subordinated to other creditor's claims.
The value of junk bonds often fluctuates in response to company, political, or
economic developments and can decline significantly over short periods of time
or during periods of general or regional economic difficulty. During those
times, the bonds may be difficult to value or sell at a fair price. Credit
ratings on junk bonds do not necessarily reflect their actual market risk.
 
The value of your shares could be adversely affected if the computer systems
used by the fund's investment advisor and the fund's other service providers are
unable to distinguish the year 2000 from the year 1900.
 
The fund's investment advisor and independent technology consultants are working
to avoid year 2000-related problems in the advisor's systems and to obtain
assurances that other service providers are taking similar steps. Year 2000
problems may also affect issuers in whose securities the fund invests.

guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.

GROWTH & INCOME FUND
 
INVESTMENT OBJECTIVES AND STRATEGIES
The fund's investment objectives are long-term capital appreciation together
with current income.
 
The fund seeks to achieve its objectives by investing at least 65% of its total
assets in a combination of blue-chip equity securities and high-quality
government bonds of U.S. and foreign issuers. "Blue chip" equity securities are
those which: (1) offered, during the issuer's most recent fiscal year, an above
average dividend yield relative to the latest reported dividend yield on the
Morgan Stanley Capital International World Index; and (2) are issued by a
company with total equity market capitalization of at least $1 billion.
High-quality government bonds are rated within one of the two highest ratings
categories of Moody's Investors Service, Inc. or Standard & Poor's, or are
deemed by the portfolio manager to be of comparable quality.
 
The fund will normally invest in securities of issuers in at least three
countries, including the United States. However, the fund may not invest more
than 40% of its assets in securities of issuers in any one country, other than
the U.S. The fund may invest up to 100% of its total assets in either equity or
debt securities in response to general economic changes and market conditions
around the world.
 
The portfolio managers allocate assets among securities of countries and in
currency denominations where opportunities for meeting the fund's investment
objective are expected to be the most attractive. The portfolio managers
consider fundamental economic strength, credit quality, and currency and
interest rate trends in emphasizing various country, geographic, and industry
sectors within the fund. Further, the portfolio managers select debt securities
of particular issuers based on additional economic and countries criteria such
as yield, maturity, issue classification, and quality characteristics. The
relative proportions of equity and debt securities held by the fund depend upon
the portfolio managers' assessment of global political and economic conditions
and the relative strengths and weaknesses of the world equity and debt markets.
Currency investments are based on economic factors (such as relative inflation,
interest rate levels and trends, growth rate forecasts, balance of payment
status, and economic policies) and on political and technical data. The
portfolio managers usually sell a particular security when any of those factors
materially changes.
 
The fund is non-diversified. This means that it may invest more than 5% of its
assets in the securities of any one issuer, with respect to 50% of its assets.
 
In anticipation of or in response to adverse market conditions or for cash
management purposes, the fund may hold or invest all or a portion of its assets
in cash (U.S. dollars, foreign currencies or multinational currency units),
money market instruments, or high-quality debt securities. As a result, the fund
may not achieve its investment objectives.
 
PRINCIPAL RISKS OF INVESTING IN THE FUND
There is a risk that you could lose all or a portion of your investment in the
fund. The value of your investment in the fund will go up and down with the
prices of the securities in which the fund invests. The prices of equity
securities change in response to many factors, including the historical and
prospective earnings of the issuer of the stock, the value of its assets,
general economic conditions, interest rates, investor perceptions, and market
liquidity. Debt securities are particularly vulnerable to credit risk and
interest rate fluctuations. When interest rates rise, bond prices fall; the
longer the bond's duration, the more sensitive it is to this risk.
 
The prices of foreign securities may be further affected by other factors
including:
 
CURRENCY EXCHANGE RATES -- The dollar value of the fund's foreign investments
will be affected by changes in the exchange rates between the dollar and the
currencies in which those investments are traded.
 
POLITICAL AND ECONOMIC CONDITIONS -- The value of the fund's foreign investments
may be adversely affected by political and social instability in their home
countries and by changes in economic or taxation policies in those countries.
 
REGULATIONS -- Foreign companies generally are subject to less stringent
regulations, including financial and accounting controls, than are U.S.

STRATEGIC INCOME FUND
 
INVESTMENT OBJECTIVES AND STRATEGIES
The fund's primary investment objective is high current income and its secondary
investment objective is capital appreciation.
 
The fund seeks to meet these objectives by investing primarily in debt
securities, including mortgage-backed and asset-backed securities, of issuers in
the United States and developed and developing countries, i.e., those that are
in the initial stages of their industrial cycles. The securities of issuers in
developing countries may consist substantially of "Brady Bonds" and other
sovereign debt securities issued by governments of such countries and traded in
the markets of developed countries or groups of developed countries without
regard to ratings. Brady Bonds are debt restructurings that provide for the
exchange of cash and loans for newly issued bonds.
 
The fund normally invests at least 35% of its total assets in U.S. and foreign
debt and other fixed-income securities that are either rated at least investment
grade by Moody's Investors Service, Inc. or Standard & Poor's (rated in the four
highest ratings categories by Moody's or S&P), or that the fund's portfolio
managers believe to be of comparable quality. The fund may invest up to 50% of
its assets in debt securities that are rated below investment grade by such
agencies or that the fund's portfolio managers believe to be of comparable
quality, i.e., "junk bonds." The fund may also invest up to 35% of its total
assets in equity securities. The fund may invest a significant portion of its
assets in the securities of U.S. issuers.
 
The portfolio managers allocate assets among securities of countries that are
expected to provide the most attractive opportunities for meeting the fund's
investment objectives. The portfolio managers consider fundamental economic
strength, credit quality, and currency and interest rate trends in emphasizing
various country, geographic and industry sectors within the fund. Further, the
portfolio managers select particular issuers based on additional economic
criteria such as yield, maturity, issue classification, and quality
characteristics. Currency investments are based on factors such as relative
inflation, interest rate levels and trends, growth rate forecasts, balance of
payments status, and economic policies. The portfolio managers usually sell a
particular security when any of those factors materially changes.
 
The fund is non-diversified. This means it may invest more than 5% of its assets
in the securities of any one issuer, with respect to 50% of its assets.
In anticipation of or in response to adverse market conditions or for cash
management purposes, the fund may hold all or a portion of its assets in cash
(U.S. dollars, foreign currencies and multinational currency units), money
market instruments, or high-quality debt securities. As a result, the fund may
not achieve its investment objectives.
 
The fund may engage in active and frequent trading of portfolio securities to
achieve its investment objectives. If the fund does trade in this way, it may
incur increased transaction costs, which can lower the actual return on your
investment. Active trading may also increase short-term capital gains and
losses, which may affect the taxes you have to pay.
 
PRINCIPAL RISKS OF INVESTING IN THE FUND
There is a risk that you could lose all or a portion of your investment in the
fund. The value of your investment in the fund will go up and down with the
prices of the securities in which the fund invests. The prices of equity
securities change in response to many factors including the historical and
prospective earnings of the issuer of the stock, the value of its assets,
general economic conditions, interest rates, investor perceptions, and market
liquidity. Debt securities are particularly vulnerable to credit risk and
interest rate fluctuations. When interest rates rise, bond prices fall; the
longer the bond's duration, the more sensitive it is to this risk.
 
The prices of foreign securities may be further affected by other factors,
including:
 
CURRENCY EXCHANGE RATES -- The dollar value of the fund's foreign investments
will be affected by changes in the exchange rates between the dollar and the
currencies in which those investments are traded.
 
POLITICAL AND ECONOMIC CONDITIONS -- The value of the fund's foreign investments
may be adversely affected by political and social instability in their home
countries and by changes in economic or taxation policies in those countries.
 
REGULATIONS -- Foreign companies generally are subject to less stringent
regulations, including financial and accounting controls, than are U.S.
companies. As a result, there generally is less publicly available information
about foreign companies than about U.S. companies.
 
MARKETS -- The securities markets of other countries are smaller than U.S.
securities markets. As a result,
 
                               Prospectus Page 24
<PAGE>
many foreign securities may be less liquid and their prices may be more volatile
than U.S. securities.
 
These factors may affect the price of common stocks issued by foreign companies
located in developing countries more than those in countries with mature
economies. For example, many developing countries have, in the past, experienced
high rates of inflation or sharply devalued their currencies against the U.S.
dollar, thereby causing the value of investments in companies located in those
countries to decline. Transaction costs are often higher in developing countries
and there may be delays in settlement procedures. In addition, developing
countries may have greater political or economic instability, less regulation
and smaller, less liquid and more volatile markets than countries with more
mature economies.
 
Sovereign debt securities of developing country governments are generally
lower-quality debt securities. Sovereign debt securities are subject to the
additional risk that, under some political, diplomatic, social, or economic
circumstances, some developing countries that issue lower quality debt
securities may be unable or unwilling to make principal or interest payments as
they come due.
 
Compared to higher-quality debt securities, junk bonds involve greater risk of
default or prices due to changes in the credit quality of the issuer because
they are generally unsecured and may be subordinated to other creditor's claims.
The value of junk bonds often fluctuates in response to company, political, or
economic developments and can decline significantly over short periods of time
or during periods of general or regional economic difficulty. During those
times, the bonds may be difficult to value or sell at a fair price. Credit
ratings on junk bonds do not necessarily reflect their actual market risk.
 
Because it is non-diversified, the fund may invest in fewer issuers than if it
were a diversified fund. Thus, the value of the fund's shares may vary more
widely, and the fund may be subject to greater investment and credit risk, than
if the fund invested more broadly.
 
The value of your shares could be adversely affected if the computer systems
used by the fund's investment advisor and the fund's other service providers are
unable to distinguish the year 2000 from the year 1900.
 
The fund's investment advisor and independent technology consultants are working
to avoid year 2000-related problems in the advisor's systems and to obtain
assurances that other service providers are taking similar steps. Year 2000
problems may also affect issuers in whose securities the fund invests.
 
An investment in the fund is not a deposit of a bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.
 
PERFORMANCE INFORMATION

GLOBAL GOVERNMENT INCOME FUND
 
                      INVESTMENT OBJECTIVES AND STRATEGIES
 
The fund's primary investment objective is high current income and its secondary
investment objectives are capital appreciation and protection of capital through
active management of its maturity structure and currency exposure.
 
The fund seeks to achieve its objective by investing at least 65% of its total
assets in debt securities (including mortgage-backed securities) issued or
guaranteed by U.S. and foreign governments or by their agencies, authorities,
and instrumentalities, as well as by supranational entities such as the World
Bank. The fund primarily invests in high quality government debt securities that
are rated in the top two ratings categories by Moody's Investors Service, Inc.
or Standard & Poor's, or deemed by the portfolio managers to be of comparable
quality. The fund may invest in lower-quality debt securities, i.e., "junk
bonds."
 
The fund may invest up to 35% of its total assets in: (1) foreign government
securities that are rated within the third and fourth highest ratings categories
by Moody's or S&P or deemed by the portfolio managers to be of comparable
quality; (2) corporate debt obligations of U.S. or foreign issuers rated at
least investment grade (rated within the four highest ratings categories by
Moody's or S&P, or deemed by the portfolio managers to be of comparable
quality); (3) privately issued mortgage-backed and asset-backed securities of
U.S. and foreign issuers that are rated at least investment grade by Moody's or
S&P, or deemed by the portfolio managers to be of comparable quality; and (4)
common stocks, preferred stocks and warrants, provided that the fund will invest
no more than 20% of its total assets in such securities.
 
The fund will normally invest in securities issued by at least three different
countries, including the United States, and may invest a significant portion of
its assets in the securities of U.S. issuers. However, the fund will invest no
more than 40% of its total assets in securities of any one country, other than
the U.S. The fund will only invest in a foreign currency or in securities
denominated in a foreign currency if the portfolio managers consider the
currency to be fully exchangeable into U.S. dollars or a multinational currency
unit.
 
The portfolio managers allocate assets among securities of countries and in
currency denominations where the combination of fixed-income market returns,
price appreciation of fixed-income securities, and currency exchange rate
movements will present opportunities for meeting the fund's investment
objectives. The principal determinants of the emphasis given to various country,
geographic, and industry sectors within the fund are fundamental economic
strength, credit quality, and currency and interest rate trends. Further, the
portfolio managers select particular issuers based on additional economic
criteria such as yield, maturity, issue classification, and quality
characteristics. Currency investments are based upon economic factors (such as
relative inflation, interest rate levels and trends, growth rate forecasts,
balance of payments status, and economic policies) and on political and
technical data. The portfolio managers usually sell a particular security when
any of those factors materially changes.
 
The fund is non-diversified. This means it may invest more than 5% of its assets
in the securities of any one issuer, with respect to 50% of its assets.
 
In anticipation of or in response to adverse market conditions or for cash
management purposes, the fund may hold all or a portion of its assets in cash
(U.S. dollars, foreign currencies and multinational currency units), money
market instruments, or high quality-debt securities. As a result, the fund may
not achieve its investment objectives.
 
The fund may engage in active and frequent trading of portfolio securities to
achieve its investment objective. If the fund does trade in this way, it may
incur increased transaction costs, which can lower the actual return on your
investment. Active trading may also increase short-term capital gains and
losses, which may affect the taxes you have to pay.
 
PRINCIPAL RISKS OF INVESTING IN THE FUND
There is a risk that you could lose all or a portion of your investment in the
fund. The value of your investment in the fund will go up and down with the
prices of the securities in which the fund invests. The prices of equity
securities change in response to many factors including the historical and
prospective earnings of the issuer of the stock, the value of its assets,
general economic conditions, interest rates, investor perceptions, and market
liquidity. Debt securities are particularly vulnerable to credit risk and
interest rate fluctuations. When interest rates rise, bond prices fall; the
longer the bond's duration, the more sensitive it is to this risk. The fund
could also lose money if any debt securities that it holds are downgraded or go
into default.
 
Mortgage-backed and asset backed securities are subject to different risks from
bonds and, as a result,
 
                               Prospectus Page 27
<PAGE>
may respond to changes in interest rates differently. If interest rates fall,
people refinance or pay off their mortgages ahead of time, which may cause
mortgage-backed securities to lose value. If interest rates rise, many people
may refinance or prepay their mortgages at a slower-than-expected rate. This may
effectively lengthen the life of mortgage-backed securities, which may cause the
securities to be more sensitive to changes in interest rates.
 
The prices of foreign securities may be further affected by other factors,
including:
 
CURRENCY EXCHANGE RATES -- The dollar value of the fund's foreign investments
will be affected by changes in the exchange rates between the dollar and the
currencies in which those investments are traded.

U.S. GOVERNMENT INCOME FUND
 
INVESTMENT OBJECTIVE AND STRATEGIES
The fund's investment objective is a high level of current income, consistent
with preservation of capital.
 
The fund seeks to achieve its objective by investing at least 65% of its total
assets in U.S. government securities including direct obligations of U.S.
Treasury and obligations issued or guaranteed by U.S. government agencies and
instrumentalities (including mortgage-backed securities). Within the latter
group are: (i) securities supported by the full faith and credit of the United
States; (ii) securities supported by the right to borrow from the U.S. Treasury;
and (iii) securities supported primarily or solely by the creditworthiness of
the issuer.
 
The fund may invest up to 35% of its total assets in: (i) foreign government
securities, including those of supranational entities such as the World Bank and
the Asian Development Bank, rated at least of investment grade (rated within the
four highest ratings categories by Moody's Investors Service, Inc. or Standard &
Poor's, or determined by the fund's sub-advisor to be of comparable quality);
(ii) U.S. government securities that are rated within the third or fourth
highest ratings categories by Moody's or S&P; (iii) privately issued mortgage-
backed or asset-backed securities that are rated at least investment grade, or
determined by the fund's sub-advisor to be of comparable quality; and (iv)
commercial paper and other short-term obligations of U.S. and foreign
corporations rated at least A-1 by S&P or Prime-1 by Moody's, or determined by
the fund's sub-advisor to be of comparable quality.
 
The fund may invest in securities issued by one country but denominated in the
currency of another country (or a multinational currency unit) but will only
invest in such securities if the fund's sub-advisor considers the currency to be
fully exchangeable into U.S. dollars or a multinational currency unit.
 
In anticipation of or in response to adverse market conditions or for cash
management purposes, the fund may hold all or a portion of its assets in cash
(U.S. dollars, foreign currencies or multinational currency units), money market
instruments, or high quality debt securities. As a result, the fund may not
achieve its investment objective.
 
The fund may engage in active and frequent trading of portfolio securities to
achieve its investment objective. If the fund does trade in this way, it may
incur increased transaction costs, which can lower the actual return on your

MONEY MARKET FUND
 
INVESTMENT OBJECTIVE AND STRATEGIES
The investment objective of the Money Market Fund is maximum current income
consistent with liquidity and conservation of capital.
 
The fund seeks to achieve its objective by investing in high-quality, U.S.
dollar denominated money market instruments. The fund seeks to maintain a net
asset value of $1.00 per share. To do so, the fund will maintain a
dollar-weighted average maturity of 90 days or less and will purchase only
instruments having remaining maturities of 13 months or less.
 
The fund may invest only in first-tier high-quality U.S. dollar-denominated
money market securities determined by the fund's sub-advisor to present minimal
credit risks. First-tier high quality securities are those that have received
the highest rating for short-term securities from at least two nationally ranked
statistical ratings organizations, such as Moody's Investors Service, Inc. or
Standard & Poor's, or were determined by the fund's sub-advisor to be of
comparable quality. These include: (i) obligations issued or guaranteed by the
U.S. and foreign governments and their agencies and instrumentalities (including
direct obligations of the U.S. Treasury, obligations backed by the full faith
and credit of U.S. government, obligations supported primarily or solely by the
creditworthiness of the issuer, and similar U.S. dollar-denominated instruments
of foreign governments and their agencies and instrumentalities); (ii)
obligations such as certificates of deposit and banker's acceptances of U.S. and
non-U.S. banks with total assets of at least $1 billion; (iii) interest-bearing
deposits in principal amounts less than the FDIC insurance limit in U.S.
commercial and savings banks with total assets of at least $1 billion, up to 5%
of the fund's assets; (iv) commercial paper and other short-term debt
obligations of U.S. and foreign companies rated at least Prime-1 by Moody's or
A-1 by S&P, or determined by the fund's sub-advisor to be of comparable quality;
and (v) repurchase agreements secured by any of the above securities.
 
In managing the fund, the portfolio managers may employ several professional
money management techniques, including varying the composition of the fund's
investments and the average weighted maturity of the Fund's securities within
the limitations described above. Decisions on whether to use such techniques are
based upon the portfolio managers' identification and assessment of the relative
values of various money market instruments and the future of interest rate
patterns, economic conditions, and shifts in fiscal and monetary policy. The
portfolio managers also may seek to improve the fund's income by purchasing and
selling securities, taking advantage of yield disparities occurring in the
market.
 
PRINCIPAL RISKS OF INVESTING IN THE FUND
An investment in the fund is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. Although the fund seeks to
preserve the value of your investment at $1.00 per share, it is possible to lose
money by investing in this fund.
 
The value of your shares could be adversely affected if the computer systems
used by the fund's investment advisor and the fund's other service providers are
unable to distinguish the year 2000 from the year 1900.
 
The fund's investment advisor and independent technology consultants are working
to avoid year 2000-related problems in the advisor's systems and to obtain
assurances that other service providers are taking similar steps. Year 2000
problems may also affect issuers in whose securities the fund invests.

<PAGE>
                                 HOW TO INVEST
 
- --------------------------------------------------------------------------------
 
The funds serve as funding vehicles for the variable annuity contracts offered
by participating insurance companies through separate accounts. Shares of the
funds may be offered to separate accounts of participating insurance companies
and serve as the underlying investments for variable annuity contracts.
 
The owners of variable annuity contracts may allocate premium payments among the
general accounts of the participating insurance companies and the divisions of
the separate accounts that correspond to the funds. Individuals may not pay
variable annuity premiums directly to the funds.
 
The variable annuity contracts are described in a separate prospectus issued by
each participating insurance company for which the companies assume no
responsibility. Individual variable annuity contract holders are not the
"shareholders" of either company or any fund. Rather, each participating
insurance company and its separate accounts are the shareholders (the
"shareholders"). In accordance with current law, shareholder voting rights will
be passed on to variable annuity contract holders. As described below, for
certain matters company shareholders vote together as a group; as to other
matters, they vote separately by fund.
 
Shares of the funds are offered and redeemed at their respective net asset
values without the addition of any sales load or redemption charge next
determined following receipt by a separate account of premium payments,
surrender requests under policies, loan payments, transfer requests, and similar
or related transactions. The funds do not issue share certificates. See "Pricing
of Shares."
 
- --------------------------------------------------------------------------------
 
                               PRICING OF SHARES
 
- --------------------------------------------------------------------------------
 
Each of the funds prices its shares based upon its net asset value. The net
asset value of a fund is equal to its total assets (consisting mainly of
portfolio securities and cash) minus its total liabilities. Each of the funds,
other than the Money Market Fund, values its portfolio securities for which
market quotations are readily available at market price. The funds value
short-term investments (maturing within 60 days) at amortized cost, which
approximates market value. The Money Market Fund values its assets at amortized
cost. When market quotations for futures and options positions held by the funds
are readily available, those positions are valued based upon such quotations.
Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based upon the prevailing exchange rates on that day. Securities and
other assets for which market quotations are not readily available are valued at
fair value determined in good faith by, or under the supervision of, the
respective fund's Board of Trustees.
 
In addition, if, between the time trading ends for a particular security and the
close of the New York Stock Exchange (NYSE), events occur that materially affect
the value of the security, the funds may value the security at its fair value as
determined in good faith by, or under the supervision of, the Board of Trustees
of the fund. Because some of the funds may invest in securities that are
primarily listed on foreign exchanges, the value of those funds' shares may
change on days when you will not be able to purchase or redeem shares.
 
Each fund determines the net asset value of its shares as of the close of
regular trading on the NYSE on each day the NYSE is open for business. The funds
price purchase, exchange, and redemption orders at the net asset value
calculated after the transfer agent receives an order in good form.

                                     TAXES
 
- --------------------------------------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS.
In general, dividends and distributions you receive from each fund are taxable
as ordinary income or capital gains for federal income tax purposes, whether you
reinvest them in additional shares or take them in cash. Distributions are
taxable to you at different rates depending upon the length of time the fund
holds its assets (i.e., short-term and long-term capital gains distributions).
Every year, an account statement showing the amount of dividends and
distributions you received from each fund during the prior year will be send to
you.
 
The Money Market Fund declares dividends from net investment income on each day
that it determines its net asset value. These dividends are usually paid on the
last calendar day of each month. The Money Market Fund generally makes
distributions of any net short-term capital gain annually after the end of its
fiscal year on December 31. The Money Market Fund does not expect to realize any
long-term capital gains. The Strategic Income Fund, the Global Government Income
Fund, and the U.S. Government Income Fund each declare and pay dividends from
net investment income, if any, and make distributions of net short-term capital
gains, if any, on a quarterly basis. The Growth & Income Fund declares and pays
dividends from net investment income, if any, and makes distributions of net
short-term capital gains, if any, on a quarterly basis. The New Pacific Fund,
the Europe Fund, the International Fund, the America Fund, the Infrastructure
Fund, the Natural Resources Fund, the Telecommunications Fund, the Latin America
Fund, and the Emerging Markets Fund each declare and pay dividends from net
investment income, if any, on an annual basis.
 
All funds, except the Money Market Fund, distribute to shareholders on an annual
basis substantially all of their net capital gains (excess of net long-term
capital gain over net short-term capital loss) and net gains from foreign
currency transactions, if any. Dividends and other distributions from a fund are
paid in additional shares of that fund at net asset value per share, unless AIM
Fund Services, Inc., the funds' transfer agent, is instructed otherwise.
 
Fund shares are offered only to separate accounts established to fund variable
annuity contracts. Under the Code, no tax is imposed on an insurance company
with respect to income of a qualifying separate account properly allocable to
the value of eligible variable annuity or variable life insurance contracts.
 
Each fund intends to continue to comply with the diversification requirements
imposed by section 817(h) of the Code and the regulations thereunder. These
requirements, which are in addition to the diversification requirements imposed
on the funds by the 1940 Act and Subchapter M of the Code, place certain
limitations on the amount of assets of each separate account -- and, because
section 817(h) and those regulations treat each fund's assets as assets of the
related separate accounts, of each fund -- that can be invested in securities of
a single issuer.
 
The foregoing is only a summary of some of the important federal income tax
considerations generally affecting the funds and the separate accounts. For
further information, see the statement of additional information and the
applicable variable annuity contract prospectus.

distinct set of investment policies. In determining the appropriate distribution
of investments among various countries and geographic regions for the Funds, AIM
and/or the sub-advisors ordinarily consider the following factors: prospects for
relative  economic growth between the different countries in which each Fund may
invest; expected levels of  inflation; government policies influencing  business
conditions;  the  outlook  for  currency relationships;  and  the  range  of the
individual investment opportunities available to international investors.
 
In analyzing companies  for possible  investment by  each Fund,  AIM and/or  the
sub-advisors  ordinarily look for one or  more of the following characteristics:
above-average earnings  growth  per  share; high  return  on  invested  capital;
healthy  balance  sheet; sound  financial  and accounting  policies  and overall
financial  strength;  strong  competitive  advantages;  effective  research  and
product  development  and  marketing;  efficient  service;  pricing flexibility;
strength of management; and general operating characteristics which will  enable
the  companies  to compete  successfully  in their  respective  marketplaces. In
certain countries, governmental restrictions and other limitations on investment
may affect the maximum percentage  of equity ownership in  any one company by  a
Fund  or the Funds in the aggregate. In addition, in some instances only special
classes of securities  may be  purchased by  foreigners and  the market  prices,
liquidity and rights with respect to those securities may vary from shares owned
by nationals.
 
In  certain  countries, governmental  and other  restrictions on  investment may
affect a  Fund's ability  to invest  in  such countries.  In addition,  in  some
instances  only special classes of securities may be purchased by foreigners and
the market price, liquidity and rights with respect to those securities may vary
from shares owned by nationals. At this  time, AIM and/ or the sub-advisors  are
not  aware of  the existence of  any investment or  exchange control regulations
which might substantially impair the operations of the Funds as described in the
Prospectus and this Statement of Additional Information. Restrictions may in the
future, however, make it undesirable to invest in certain countries. None of the
Funds has  a present  intention  of making  any  significant investment  in  any
country  or  stock market  in  which AIM  and/or  the sub-advisors  consider the
political or economic  situation to threaten  a Fund with  substantial or  total
loss of its investment in such country or market.
 
    THE  NEW  PACIFIC FUND,  THE EUROPE  FUND, AND  THE INTERNATIONAL  FUND. For
purposes of this  Statement of  Additional Information, an  issuer typically  is
considered  as domiciled in a  particular country if it  is: (a) organized under
the laws  of, or  has its  principal office  in, a  particular country;  or  (b)
normally   derives  50%  or  more  of   its  total  revenues  from  business  in
 
                   Statement of Additional Information Page 2

that country, provided that, in the  view of AIM and/or the Fund's  sub-advisor,
the   value  of  such  issuer's  securities  tends  to  reflect  such  country's
development to a greater extent than developments elsewhere. However, these  are
not  absolute requirements, and  certain companies incorporated  in a particular
country and considered  by AIM and/or  the Funds' sub-advisor  to be located  in
that  country  may have  substantial foreign  operations or  subsidiaries and/or
export sales exceeding in size the assets or sales in that country. From time to
time, the Board  of Trustees of  a Fund may  add or delete  countries from  that
Fund's primary investment area.
 
Each Fund may invest up to 35% of its assets in the equity securities of issuers
domiciled  outside of its primary investment  area, including: (i) securities of
issuers not domiciled  in the primary  investment area but  which are linked  by
tradition,  economic markets, cultural similarities or geography to such primary
investment area; and (ii) securities of issuers domiciled elsewhere in the world
that have operations  in the primary  investment area or  that stand to  benefit
from political and economic events in the primary investment area.
 
Among  the factors considered by AIM  and/or the Funds' sub-advisor in selecting
markets in which  to invest  are that several  markets included  in the  primary
investment areas of the New Pacific Fund, the Europe Fund, and the International
Fund are so-called developing countries and their economies and markets are less
developed  and more  prone to uncertainty,  instability and risk  than the other
markets in which such Funds invest.
 
Under normal circumstances, the assets of the International Fund are invested in
the  equity  securities  of  issuers  domiciled  in  at  least  three  different
countries.
 
    THE  AMERICA FUND.  The Fund's process  for selecting  mid-cap growth stocks
consists of four components:  asset allocation, industry diversification,  stock
selection  and quality control. The  quality control process ensures consistency
with the  industry  and  asset  allocation  guidelines  as  well  as  the  stock
guideline.  There is no assurance that this  process will produce better or more
consistent results than other investment processes.
 
    THE EMERGING MARKETS FUND. The Emerging  Markets Fund does not consider  the
following countries to be emerging markets: Australia, Austria, Belgium, Canada,
Denmark,   England,  Finland,  France,  Germany,   Ireland,  Italy,  Japan,  the
Netherlands, New Zealand,  Norway, Spain,  Sweden, Switzerland,  and the  United
States.   In  determining   what  countries  constitute   emerging  markets  the
Sub-advisor will consider, among other things, data analysis, and classification
of  countries  published   or  disseminated  by   the  International  Bank   for
Reconstruction  and  Development  (commonly known  as  the World  Bank)  and the
International Finance Corporation.
 
    THE EMERGING  MARKETS  FUND AND  THE  STRATEGIC INCOME  FUND.  The  Emerging
Markets Fund and the Strategic Income Fund will consider investment in following
emerging markets:

Although  the Emerging Markets Fund and  the Strategic Income Fund each consider
all of the  above-listed countries  eligible for  investment, they  will not  be
invested  in all such markets at all times. Moreover, investing in some of those
markets currently may not be desirable or feasible, due to the lack of  adequate
custody  arrangements for the Funds'  assets, overly burdensome repatriation and
similar restrictions,  the  lack of  organized  and liquid  securities  markets,
unacceptable political risks, or for other reasons.
 
The  Emerging  Markets  Fund  may  invest  in  common  stock,  preferred  stock,
securities convertible into common  stock, rights and  warrants to acquire  such
securities,  and  substantially similar  forms  of equity  with  comparable risk
characteristics. A company in an "emerging  market" is an entity: (i) for  which
the  principal trading market is an emerging market, as defined above; (ii) that
(alone or on a consolidated basis) derives 50% or more of its total revenue from
either goods produced, sales made, or services performed in emerging markets; or
(iii) organized under the laws  of, or with a  principal office in, an  emerging
market.  The Fund  may invest  up to 35%  of its  total assets  in securities of
issuers not included in the list of emerging markets above, if investing therein
becomes feasible and desirable subsequent to date of this prospectus. Growth  of
capital  in debt securities in  which the Fund invests may  arise as a result of
favorable changes  in  relative foreign  exchange  rates, in  relative  interest
levels  and/or in  the creditworthiness of  issuers. The receipt  of income from
debt securities owned by  the Fund is incidental  to its objective of  long-term
growth of capital.
 
The  Strategic  Income  Fund  selects  debt  securities  from  those  issued  by
governments, their  agencies and  instrumentalities; central  banks;  commercial
banks;  and  other corporate  entities. Debt  securities in  which the  Fund may
invest  include  bonds,  notes,   debentures,  and  other  similar   instruments
(including  mortgage-backed and  asset-backed securities  of foreign  issuers as
well as domestic issuers). The Fund  considers "emerging markets" to consist  of
all countries determined by AIM and/or the Fund's sub-advisor to have developing
or  emerging  economies  or  markets. These  countries  generally  include every
country in the  world except the  United States, Canada,  Japan, Australia,  New
Zealand and most countries in Western Europe.
 
    THE  INFRASTRUCTURE FUND. The Fund may  invest, in addition to common stock,
in the preferred stock and warrants to acquire common and preferred stock issued
by infrastructure companies.
 
In addition to the types of  infrastructure companies listed in the  Prospectus,
the  Fund may also invest  in companies engaged in  the designing, developing or
providing of: (i) electricity production; (ii) steel, concrete, or similar types
of products;  (iii) mobile  communications and  cellular radio/paging;  emerging
technologies  combining telephone, television and/or  computer systems; and (iv)
other products and services which, in the judgment of AIM and/or the Fund's sub-
advisor, constitute  services  significant to  the  development of  a  country's
infrastructure.
 
AIM  and the Fund's  sub-advisor believe that a  country's infrastructure is one
key to  the long-term  success of  that country's  economy. AIM  and the  Fund's
sub-advisor  also  believe  that  adequate  energy,  transportation,  water  and
communications systems are essential for long-term economic growth. AIM and  the
Fund's  sub-advisor believe that many developing nations, especially in Asia and
Latin America, plan to make significant expenditures to the development of their
infrastructure in the coming  years, which is  expected to facilitate  increased
levels of and services and manufactured goods.
 
In  the developed countries of North America, Europe, Japan and the Pacific Rim,
AIM and/or the  Fund's sub-advisor expect  that the replacement  and upgrade  of
transportation  and  communications  systems  should  stimulate  growth  in  the
infrastructure industries of those  countries. In addition, in  the view of  AIM
and  the Fund's sub-advisor, deregulation of telecommunications and electric and
gas utilities  in  many countries  is  promoting significant  changes  in  these
industries.
 
AIM and the Fund's sub-advisor believe that strong economic growth in developing
countries  and  infrastructure replacement,  upgrade,  and deregulation  in more
developed  countries   provide   an   environment   for   favorable   investment
opportunities  in infrastructure companies worldwide. In addition, the long-term
growth rates of certain foreign countries' economies may be substantially higher
than the  long-term growth  rate of  the  U.S. economy.  An integral  aspect  of
certain foreign countries' economic growth may be the development or improvement
of their infrastructure.
 
    THE  NATURAL RESOURCES FUND. With respect to the Natural Resources Fund, AIM
has identified four areas that it expects will create investment  opportunities:
(i)  improving supply/demand fundamentals, which  may result in higher commodity
prices; (ii)  privatization of  state-owned natural  resource businesses;  (iii)
management  which  can improve  production efficiencies  without correspondingly
increasing  commodity  prices;   and  (iv)  service   companies  with   emerging
technologies  that  can  enhance  productivity or  reduce  production  costs. Of
course, there is no  certainty that these factors  will produce the  anticipated
results.
 
The  Fund may invest,  in addition to  common stock, in  the preferred stock and
warrants to  acquire  common and  preferred  stock issued  by  natural  resource
companies.
 
                   Statement of Additional Information Page 4
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
 
In  addition  to  the  types  of  natural  resources  companies  listed  in  the
Prospectus, the  Fund  may also  invest  in  companies which  own,  explore,  or
develop:  (i) energy sources such as gas  and coal; (ii) ferrous and non-ferrous
metals (such as iron, aluminum, copper, nickel, zinc and lead), strategic metals
(such as uranium  and titanium) and  precious metals (such  as gold, silver  and
platinum);  (iii)  forest products  (such as  timber,  coated and  uncoated tree
sheet, pulp and newsprint); refined products (such as chemicals and steel);  and
(iv) other products and services which, in the judgment of AIM and/or the Fund's
sub-advisor,  are  significant  to  the  ownership  and  development  of natural
resources and other basic commodities.
 
AIM and/or the  Fund's sub-advisor  will allocate the  Fund's investments  among
those  natural  resource  companies  depending  on  their  assessment  of  their
long-term growth  potential.  In  assessing these  companies'  long-term  growth
potential,  AIM and/or the sub-advisor will evaluate, among other factors, their
capabilities for  expanded  exploration  and  production,  superior  exploration
programs and production techniques and facilities, current inventories, expected
production and demand levels, and the potential to accumulate new resources.
 
AIM  and  the Fund's  sub-advisor believe  that  the liberalization  of formerly
socialist economies will  bring about dramatic  changes in both  the supply  and
demand for natural resources. In addition, rapid industrialization in developing
countries  of Asia  and Latin America  is generating new  demands for industrial
materials that  are affecting  world  commodities markets.  AIM and  the  Fund's
sub-advisor  believe there changes are likely to create investment opportunities
that benefit  from new  sources of  supply and/or  from changes  in  commodities
prices.
 
AIM and the Fund's sub-advisor also believe that investments in natural resource
industries  offer an opportunity  to protect wealth  against the capital eroding
effects of  inflation.  During periods  of  accelerating inflation  or  currency
uncertainty,  worldwide  investment demand  for natural  resources, particularly
precious metals,  tends  to increase,  and  during periods  of  disinflation  or
currency stability, it tends to decrease. AIM and the Fund's sub-advisor believe
that  rising commodity prices and increasing worldwide industrial production may
favorably affect share prices of natural resource companies, and investments  in
such  companies  can  offer excellent  opportunities  to offset  the  effects of
inflation.
 
    THE TELECOMMUNICATIONS FUND.  With respect to  the Telecommunications  Fund,
AIM   has  identified  four  areas  that   it  expects  will  create  investment
opportunities and  lead  to  growth  in the  sector:  (i)  the  deregulation  of
companies  in  the industry,  which will  allow  competition to  promote greater
efficiencies;  (ii)   the   privatization  of   state-owned   telecommunications
businesses;  (iii) the development of infrastructure in underdeveloped countries
and upgrading of services  in other countries;  and (iv) emerging  technologies,
that  will  enhance  productivity  and reduce  costs  in  the telecommunications
industry. Of course, there is no  certainty that these factors will produce  the
anticipated results.
 
The  Fund may invest,  in addition to  common stock, in  the preferred stock and
warrants to  acquire common  and preferred  stock issued  by  telecommunications
companies.
 
Telecommunications  companies cover a variety of sectors, ranging from companies
concentrating on established technologies to those primarily engaged in emerging
or developing technologies.  The characteristics  of companies  focusing on  the
same technology will vary among countries depending upon the extent to which the
technology  is  established in  the particular  country.  AIM and/or  the Fund's
sub-advisor will allocate the Fund's  investments among these sectors  depending
upon  their  assessment  of  the relative  long-term  growth  potentials  of the
sectors.
 
In  addition  to  the  types  of  telecommunications  companies  listed  in  the
Prospectus,  the Fund  may also  invest in  companies designing,  developing, or
providing the following products and services: cellular radio paging; electronic
mail; local and  wide area networking  and linkage of  word and data  processing
systems;  publishing  and  information  systems;  videotext  and  teletext;  and
emerging technologies combining telephone, television and/or computer systems.
 
AIM and/or the Fund's sub-advisor expect that, from time to time, a  significant
portion  of the  Fund's assets  may be  invested in  the securities  of domestic
issuers. Telecommunications,  however, is  a global  industry with  significant,
growing  markets  outside of  the  United States.  A  sizable proportion  of the
companies  that  comprise  the  telecommunications  industry  are  headquartered
outside  of  the  United  States.  For  these  reasons,  AIM  and/or  the Fund's
sub-advisor believe  that  a portfolio  comprised  only of  securities  of  U.S.
issuers   does  not   provide  the   greatest  potential   for  return   from  a
telecommunications investment.  AIM  and/or  the Fund's  sub-advisor  use  their
financial  expertise in  markets located throughout  the world  in attempting to
identify those  countries and  telecommunications companies  then providing  the
greatest  potential  for long-term  capital appreciation.  In this  fashion, AIM
and/or the  Fund's sub-advisor  and  the Fund  seek  to enable  shareholders  to
capitalize  on the  substantial investment  opportunities and  the potential for
long-term growth of capital presented by the global telecommunications industry.
AIM and/or  the  Fund's  sub-advisor  will  allocate  the  Fund's  assets  among
securities of countries and in currency denominations and industry sectors where
opportunities for meeting the Fund's investment objective are expected to be the
most attractive.
 
                   Statement of Additional Information Page 5
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
 
AIM  and/or  the Fund's  sub-advisor believe  that  there are  opportunities for
continued growth  in  demand for  components,  products, media  and  systems  to
collect,  store, retrieve, transmit, process,  distribute, record, reproduce and
use information. The pervasive societal impact of communications and information
technologies has been  accelerated by  the lower costs  and higher  efficiencies
that  result  from the  blending of  computers with  telecommunications systems.
Accordingly, companies engaged in the production of methods for using electronic
and, potentially, video technology to communicate information are expected to be
important in the Fund's portfolio.  Older technologies, such as photography  and
print, also may be represented, however.
 
    THE  GROWTH & INCOME FUND. With respect to the Growth & Income Fund, AIM and
the Fund's sub-advisor attempt to identify those countries and industries  where
economic  and political factors are likely to produce above-average growth rates
and to further identify companies in such countries and industries that are best
positioned and managed  to benefit  from these factors.  In evaluating  possible
equity  investments,  AIM and  the Fund's  sub-advisor  attempt to  identify and
acquire only  securities they  deem to  represent high  or improving  investment
quality.  Securities representing high investment quality generally will include
those of well-known, established and successful issuers that AIM and the  Fund's
sub-advisor  believe will  continue to be  successful in  the future. Securities
representing improving investment quality may include those of an issuer  which,
for  instance, has improved  its sales or  earnings or of  an issuer the balance
sheet and  financial  condition of  which  are  improving. AIM  and  the  Fund's
sub-advisor  seek to  avoid investing  in equity  securities that  appear overly
speculative or  risky,  even  if  they have  otherwise  attractive  features  or
investment potential.
 
In  evaluating debt securities considered for  investment by the Growth & Income
Fund, AIM  and  the Fund's  sub-advisor  analyze their  yield,  maturity,  issue
classification  and quality characteristics, coupled with expectations regarding
the local  and world  economies, movements  in  the general  level and  term  of
interest  rates, currency values, political  developments, and variations of the
supply of funds available  for investment in the  world bond market relative  to
the  demands placed  upon it.  AIM and the  Fund's sub-advisor  may increase the
average maturity  of  the  portion  of the  Fund's  holdings  invested  in  debt
obligations  when they expect  interest rates to decline,  and may decrease such
maturity when they expect  interest rates to rise.  There are no limitations  on
the  maximum  or minimum  maturities of  the debt  securities considered  by the
Growth & Income Fund for investment or  on the average weighted maturity of  the
debt  portion of the  Fund's holdings. Should  the rating of  a debt security be
revised while such security is  owned by the Growth &  Income Fund, AIM and  the
Fund's  sub-advisor  will  evaluate what  action,  if any,  is  appropriate with
respect to such security. See "Description of Debt Ratings."
 
The Fund may invest  in common stock, preferred  stock, and warrants to  acquire
such  securities, and other equity securities.  The debt obligations held by the
Fund may include debt obligations  convertible into equity securities or  having
attached  warrants or rights  to purchase equity  securities. The Fund currently
contemplates that it  will invest principally  in securities of  issuers in  the
United  States,  Canada,  Japan, the  Western  Europe nations,  New  Zealand and
Australia. The Fund may purchase securities of an issuer located in one  country
but  denominated in the currency of another country (or a multinational currency
unit).
 
    THE LATIN AMERICA FUND. Several  Latin American countries have adopted  debt
conversion  programs, pursuant  to which  investors may  use external  debt of a
country, directly or  indirectly, to  make investments in  local companies.  The
terms  of  the various  programs  vary from  country  to country,  although each
program includes significant  restrictions on  the application  of the  proceeds
received  in the conversion and  on the remittance of  profits on the investment
and of the invested capital. The Latin America Fund intends to acquire Sovereign
Debt to  hold and  trade in  appropriate circumstances,  as well  as to  use  to
participate  in Latin American  debt conversion programs.  See "Risk Factors" in
the Funds' Prospectus and "Risk Factors"  below. AIM and the Fund's  sub-advisor
will  evaluate opportunities to enter into  debt conversion transactions as they
arise but do not currently  intend to invest more than  5% of the Latin  America
Fund's assets in such programs.
 
The  Fund  may invest  in common  stock, preferred  stock, rights,  warrants and
securities convertible into common stock, and other substantially similar  forms
of  equity securities  with comparable risk  characteristics, as  well as bonds,
notes, debentures, or other forms of  indebtedness that may be developed in  the
future.
 
Unless  otherwise  indicated,  the Fund  defines  Latin America  to  include the
following countries: Argentina, the Bahamas, Barbados, Belize, Bolivia,  Brazil,
Chile,  Colombia, Costa Rica,  Dominican Republic, Ecuador,  El Salvador, French
Guiana, Guatemala,  Guyana, Haiti,  Honduras, Jamaica,  Mexico, the  Netherlands
Antilles,  Nicaragua,  Panama, Paraguay,  Peru,  Suriname, Trinidad  and Tobago,
Uruguay and Venezuela.
 
                   Statement of Additional Information Page 6
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
 
Capital appreciation in  debt securities may  arise as a  result of a  favorable
change  in relative  foreign exchange  rates, in  relative interest  rate levels
and/or in the creditworthiness of issuers. The receipt of income from such  debt
securities  owned by the Fund  is incidental to the  Fund's objective of capital
appreciation.
 
For purposes  of  defining  Latin  American issuers,  the  Fund's  purchases  of
securities  issued  outside of  Latin America  to  finance their  Latin American
operations will be limited to securities the performance of which is  materially
related  to such company's Latin  American activities. In evaluating investments
in securities of U.S. issuers, AIM and/or the Fund's sub-advisor will  consider,
among  other factors,  the issuer's Latin  American business  activities and the
impact that developments in  Latin America may have  on the issuer's  operations
and financial condition.
 
Certain  sectors of the economies of certain Latin American countries are closed
to equity investments by foreigners. Further,  due to the absence of  securities
markets  and  publicly  owned corporations  and  due to  restrictions  on direct
investment by foreign entities in certain Latin American countries, the Fund may
be able to invest in such  countries solely or primarily through  governmentally
approved  investment  vehicles or  companies. In  addition,  the portion  of the
Fund's assets directly invested in Chile  may be less than the portion  invested
in other Latin American countries because, at present, capital directly invested
in  Chile normally cannot be repatriated for at least one year. As a result, the
Fund currently intends  to limit  most of  its Chilean  investments to  indirect
investments  through  American  Depositary  Receipts  ("ADRs")  and  established
Chilean  investment  companies,  the  shares   of  which  are  not  subject   to
repatriation restrictions.
 
    THE  GLOBAL GOVERNMENT INCOME FUND. The  Fund currently contemplates that it
will invest principally in obligations of the United States, Canada, Japan,  the
Western European nations, New Zealand and Australia, as well as in multinational
currency units.
 
The  U.S.  government securities  in which  the Fund  may invest  include direct
obligations of the U.S. Treasury (such  as Treasury bills, notes and bonds)  and
obligations   issued   or   guaranteed   by   U.S.   Government   agencies   and
instrumentalities, including securities that are supported by the full faith and
credit of the United  States (such as  Government National Mortgage  Association
("GNMA") certificates), securities that are supported by the right of the issuer
to  borrow from the U.S.  Treasury (such as securities  of the Federal Home Loan

AIM and/or the Fund's sub-advisor select securities of particular issuers on the
basis of their views  as to the  best values in  the marketplace. This  judgment
involves  expectations  regarding local  and world  economies, movements  in the
general  level  and   term  of  interest   rates,  currency  values,   political
developments, and variations of supply and demand.
 
    THE  U.S. GOVERNMENT  INCOME FUND.  The Fund  may invest  in U.S. government
securities including: direct obligations of  the U.S Treasury (such as  Treasury
bills,  notes,  and  bonds);  and  obligations  issued  or  guaranteed  by  U.S.
government  agencies  and  instrumentalities,  including  securities  that   are
supported  by  the full  faith and  credit of  the United  States (such  as GNMA
certificates), securities  that are  supported by  the right  of the  issuer  to
borrow  from the U.S. Treasury (such as  securities of the FHLBs) and securities
supported primarily or  solely by the  creditworthiness of the  issuer (such  as
securities of Fannie Mae, FHMLC, SLMA and TVA).
 
U.S.  government securities in which the Fund may invest include mortgage backed
securities, which are issued or guaranteed as to principal and interest by GNMA,
Fannie Mae,  FHMLC or  other government-sponsored  enterprises. Such  securities
include fixed-rate mortgage obligations, collateralized mortgage obligations and
adjustable rate mortgages.
 
Treasury  bills, notes and bonds and other  obligations backed by the full faith
and credit pledge of the U.S. government historically have involved little  risk
of loss of principal if held to maturity. While not backed by the full faith and
credit  pledge of the U.S. government, securities issued or guaranteed by Fannie
Mae or  FHLMC are  high quality  investments having  minimal credit  risks.  All
securities  in which  the Fund  invests, however,  are subject  to variations in
market value due to interest rate fluctuations.
 
A number of U.S. government agencies or government-sponsored organizations  also
sell their own debt securities. These agencies typically are created by Congress
to  fulfill a  specific function,  such as  providing credit  to home  buyers or
farmers; for example, FHLBs, Federal Farm Credit Banks, and SLMA. Some of  these
obligations  are backed by the full faith  and credit of the U.S. government, as
noted above, and some are supported primarily or solely by the  creditworthiness
of   the  issuing  agency,  such  as  those  issued  by  TVA.  These  securities
traditionally offer somewhat higher yields than U.S. Treasury securities  having
similar maturities but may have greater principal risk.

The  Fund  may invest  in  bonds issued  by  the Resolution  Funding Corporation
("Refcorp") whose interest payments are guaranteed by U.S. Treasury zero  coupon
bonds.  The amount and  maturity date of the  Refcorp bonds are  the same as the
amount and maturity date  of the corresponding U.S.  Treasury zero coupon  bonds
held in a separate custody account at the Federal Reserve Bank of New York. Upon
maturity,  the Refcorp  bonds will  be repaid  from the  proceeds of  those U.S.
Treasury zero coupon bonds maturing on the same date.
 
    MONEY MARKET FUND. Commercial  paper may include  corporate bonds and  notes
(corporate  obligations that  mature, or  that may be  redeemed, in  one year or
less). These corporate obligations include variable rate master notes, which are
redeemable upon notice and permit  investment in fluctuating amounts at  varying
rates  of  interest  pursuant to  direct  arrangements  with the  issuer  of the
instrument. In  addition  to the  foregoing  securities, the  Fund  may  acquire
participation  interests  in  securities in  which  it is  permitted  to invest.
Participation interests are pro rata interests in securities held by others.
 
MORTGAGE-BACKED AND ASSET-BACKED SECURITIES
The Strategic Income  Fund, Global  Government Income Fund  and U.S.  Government
Income  Fund  may  invest in  mortgage-backed  securities,  including fixed-rate
mortgage  obligations,  adjustable  rate   mortgage  obligations  ("ARMs")   and
collateralized  mortgage obligations.  Each of  these Funds  may also  invest in
asset-backed securities.
 
Mortgage-backed securities may  be composed of  one or more  classes and may  be
structured either as pass-through securities or collateralized debt obligations.
Multiple-class  pass  through  securities  and  mortgage-backed  securities  are
referred to in this Statement of Additional Information as "CMOs." Some CMOs are
directly supported by other CMOs, which in turn are supported by mortgage pools.
Investors typically receive payments  out of the interest  and principal on  the
underlying  mortgages. The portions of these payments that investors receive, as
well as the priority of their rights to receive payments, are determined by  the
specific terms of the CMO class.
 
When   interest  rates  go  down   and  homeowners  refinance  their  mortgages,
mortgage-backed bonds may be paid off more quickly than investors expect.
 
When interest rates rise, mortgage-backed bonds may be paid off more slowly than
originally expected. Changes  in the rate  or "speed" of  these prepayments  can
cause  the value of mortgage-backed securities  to fluctuate to a greater degree
and more rapidly than ordinary fixed income securities.
 
Other asset-backed securities are similar to mortgage-backed securities,  except
that  the underlying assets are different. These underlying assets may be nearly
any type of  financial asset or  receivable, such as  motor vehicle  installment
sales contracts, home equity loans, leases of various types of real and personal
property  and receivables  from credit  cards. Like  mortgage-backed securities,
asset-backed securities can change in value in response to interest rate changes
to a greater degree and more rapidly than ordinary fixed income securities.
 
Mortgage-backed securities represent  direct or indirect  participations in,  or
are  secured by and  payable from, mortgage  loans secured by  real property and
include single-  and  multi-class  pass-through  securities  and  collateralized
mortgage  obligations. The  U.S. government mortgage-backed  securities in which
the Funds may invest include mortgage-backed securities issued or guaranteed  as
to  the payment of  principal and interest (but  not as to  market value) by the
Government National Mortgage  Association ("GNMA"), Fannie  Mae, or the  Federal
Home Loan Mortgage Corporation ("Freddie Mac"). Other mortgage-backed securities
are  issued  by  private  issuers, generally  originators  of  and  investors in
mortgage loans,  including savings  associations, mortgage  bankers,  commercial
banks,  investment bankers  and special purpose  entities (collectively "Private
Mortgage Lenders").  Payments of  principal  and interest  (but not  the  market
value)  of such private mortgage-backed securities  may be supported by pools of
mortgage loans or other mortgage-backed securities that are guaranteed, directly
or  indirectly,   by  the   U.S.  government   or  one   of  its   agencies   or
instrumentalities, or they may be issued without any government guarantee of the
underlying   mortgage  assets  but  with  some  form  of  non-government  credit
enhancement. New types of mortgage-backed securities are developed and  marketed
from  time  to time  and,  consistent with  its  investment limitations,  a Fund
expects to invest  in those  new types  of mortgage-backed  securities that  AIM
and/or  the Fund's  sub-advisor believes may  assist that Fund  in achieving its
investment objective. Similarly, a Fund may invest in mortgage-backed securities
issued by  new or  existing governmental  or private  issuers other  than  those
identified herein.
 
Asset-backed    securities   have   structural    characteristics   similar   to
mortgage-backed securities. However,  the underlying assets  are not first  lien
mortgage  loans or interests  therein, but include assets  such as motor vehicle
installment sale contracts, other installment sale contracts, home equity loans,
leases of  various types  of real  and personal  property and  receivables  from
revolving  credit (credit card) agreements.  Such assets are securitized through
the use of trusts or special purpose corporations. Payments or distributions  of
principal   and  interest  may  be  guaranteed   up  to  a  certain  amount  and
 
                   Statement of Additional Information Page 8

for a certain time period by a letter of credit or pool insurance policy  issued
by  a  financial  institution  unaffiliated with  the  issuer,  or  other credit
enhancements may be present.
 
The yield characteristics of mortgage-backed and asset-backed securities  differ
from  those of traditional debt securities. Among the major differences are that
interest and principal payments are  made more frequently, usually monthly,  and
that principal may be prepaid at any time because the underlying mortgagee loans
or other obligations generally may be prepaid at any time. Prepayments on a pool
of  mortgage loans are  influenced by a variety  of economic, geographic, social
and  other  factors,  including  changes  in  mortgagors'  housing  needs,   job
transfers,  unemployment, mortgagors' net equity in the mortgaged properties and
servicing decisions.  Generally,  however, prepayments  on  fixed-rate  mortgage
loans will
increase  during a period of falling interest rates and decrease during a period
of rising interest rates. Similar  factors apply to prepayments on  asset-backed
securities, but the receivables underlying asset-backed securities generally are
of  a  shorter  maturity and  thus  are  less likely  to  experience substantial
prepayments. Such securities, however, often  provide that for a specified  time
period  the issuers will  replace receivables in  the pool that  are repaid with
comparable obligations. If the issuer is unable to do so, repayment of principal
on the asset-backed securities may commence at an earlier date.  Mortgage-backed
and  asset-backed securities may decrease  in value as a  result of increases in
interest rates  and may  benefit less  than other  fixed-income securities  from
declining interest rates because of the risk of prepayment.
 
The  rate of interest  on mortgage-backed securities is  lower than the interest
rates paid on the mortgages  included in the underlying  pool due to the  annual
fees  paid to  the servicer  of the  mortgage pool  for passing  through monthly
payments to  certificateholders and  to  any guarantor,  and  due to  any  yield
retained  by the  issuer. Actual yield  to the  holder may vary  from the coupon
rate, even if  adjustable, if  the mortgage-backed securities  are purchased  or
traded  in the secondary market at a  premium or discount. In addition, there is
normally some delay between the time the issuer receives mortgage payments  from
the  servicer and the time the issuer  makes the payments on the mortgage-backed
securities, and this  delay reduces the  effective yield to  the holder of  such
securities.
 
Yields on pass-through securities are typically quoted by investment dealers and
vendors  based on the maturity of  the underlying instruments and the associated
average life assumption. The average life of a pass-through pool varies with the
maturities of the underlying mortgage loans.  A pool's term may be shortened  by
unscheduled  or early payments of principal on the underlying mortgages. Because
prepayment rates of individual pools vary widely, it is not possible to  predict
accurately the average life of a particular pool. In the past, a common industry
practice was to assume that prepayments on pools of fixed rate 30-year mortgages
would result in a 12-year average life for the pool. At present, mortgage pools,
particularly   those   with   loans   with   other   maturities   or   different
characteristics, are priced on an assumption of average life determined for each
pool. In periods of  declining interest rates, the  rate of prepayment tends  to
increase,   thereby  shortening   the  actual   average  life   of  a   pool  of
mortgage-related securities. Conversely,  in periods of  rising interest  rates,
the rate of prepayment tends to decrease, thereby lengthening the actual average
life  of the pool. However,  these effects may not be  present, or may differ in
degree, if the  mortgage loans in  the pools have  adjustable interest rates  or
other  special payment  terms, such  as a  prepayment charge.  Actual prepayment
experience may cause the yield of mortgage-backed securities to differ from  the
assumed  average  life yield.  Reinvestment of  prepayments  may occur  at lower
interest rates than the original investment, thus adversely affecting the  yield
of a Fund.
 
    GNMA   CERTIFICATES.   GNMA   guarantees   certain   mortgage   pass-through
certificates ("GNMA  certificates"),  issued  by Private  Mortgage  Lenders  and
representing  ownership interests  in individual  pools of  residential mortgage
loans. These securities are designed to provide monthly payments of interest and
principal to the investor. Timely payment of interest and principal is backed by
the full  faith and  credit of  the U.S.  government. Each  mortgagor's  monthly
payments  to his  lending institution  on his  residential mortgage  are "passed
through" to  certificateholders such  as the  Funds. Mortgage  pools consist  of
whole  mortgage loans or participations in  loans. The terms and characteristics
of the mortgage  instruments are generally  uniform within a  pool but may  vary
among  pools. Lending  institutions that originate  mortgages for  the pools are
subject to certain standards, including  credit and other underwriting  criteria
for individual mortgages included in the pools.
 
    FANNIE  MAE CERTIFICATES. Fannie Mae facilitates a national secondary market
in residential mortgagee loans insured or guaranteed by U.S. government agencies
and in  privately insured  or uninsured  residential mortgage  loans  (sometimes
referred  to as "conventional  mortgage loans" or  "conventional loans") through
its mortgage purchase  and mortgage-backed securities  sales activities.  Fannie
Mae   issues   guaranteed  mortgage   pass-through  certificates   ("Fannie  Mae
certificates"), which represent pro  rata shares of  all interest and  principal
payments  made and  owed on the  underlying pools. Fannie  Mae guarantees timely
payment of interest  and principal on  Fannie Mae certificates.  The Fannie  Mae
guarantee is not backed by the full faith and credit of the U.S. government.

    FREDDIE  MAC CERTIFICATES. Freddie  Mac also facilitates  a secondary market
for conventional residential and U.S. government-insured mortgage loans  through
its  mortgage purchase and mortgage-backed  securities sales activities. Freddie
Mac issues two types of mortgage pass-through securities: mortgage participation
certificates ("PCs")  and guaranteed  mortgage  certificates ("GMCs").  Each  PC
represents a pro rata share of all interest and principal payments made and owed
on  the underlying pool. Freddie Mac generally guarantees timely monthly payment
of interest on PCs and the ultimate payment  of principal, but it also has a  PC
program under which it guarantees timely payment of both principal and interest.
GMCs  also  represent  a  pro  rata  interest  in  a  pool  of  mortgages. These
instruments, however, pay  interest semi-annually  and return  principal once  a
year  in guaranteed minimum payments. The Freddie Mac guarantee is not backed by
the full faith and credit of the U.S. government.
 
    PRIVATE,  RTC  AND   SIMILAR  MORTGAGE-BACKED  SECURITIES.   Mortgage-backed
securities  issued by Private  Mortgage Lenders are  structured similarly to the
pass-through  certificates  and  collateralized  mortgage  obligations  ("CMOs")
issued  or guaranteed by GNMA, Fannie  Mae and Freddie Mac. Such mortgage-backed
securities may be  supported by pools  of U.S. government  or agency insured  or
guaranteed  mortgage loans  or by other  mortgage-backed securities  issued by a
government agency or instrumentality; but they generally are supported 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  GNMA, Fannie Mae and  Freddie Mac, they normally
are structured with one or  more types of credit  enhancement. See "-- Types  of
Credit  Enhancement." These  credit enhancements  do not  protect investors from
changes in market value.
 
The Resolution  Trust  Corporation ("RTC"),  which  was organized  by  the  U.S.
government in connection with the savings and loan crisis, held assets of failed
savings  associations as either a conservator or receiver for such associations,
or it acquired  such assets in  its corporate capacity.  These assets  included,
among  other things,  single family and  multifamily mortgage loans,  as well as
commercial mortgage loans.  In order  to dispose of  such assets  in an  orderly
manner,  RTC established a vehicle registered with the SEC through which it sold
mortgage-backed securities. RTC  mortgage-backed securities  represent pro  rata
interests  in pools of  mortgage loans that  RTC held or  acquired, as described
above, and  are  supported  by one  or  more  of the  types  of  private  credit
enhancements used by Private Mortgage Lenders.
 
    COLLATERALIZED MORTGAGE OBLIGATIONS AND MULTI-CLASS MORTGAGE
PASS-THROUGHS.  CMOs are  debt obligations  that are  collateralized by mortgage
loans or mortgage  pass-through securities (such  collateral collectively  being
called  "Mortgage Assets"). CMOs may be issued by Private Mortgage Lenders or by
government entities  such as  Fannie Mae  or Freddie  Mac. Multi-class  mortgage
pass-through  securities are interests in trusts  that are comprised of Mortgage
Assets and  that have  multiple classes  similar to  those in  CMOs. Unless  the
context  indicates  otherwise,  references herein  to  CMOs  include multi-class
mortgage pass-through securities. Payments of principal of, and interest on, the
Mortgage Assets  (and in  the case  of CMOs,  any reinvestment  income  thereon)
provide  the  funds  to  pay debt  service  on  the CMOs  or  to  make scheduled
distributions on the multi-class mortgage pass-through securities.
 
In a CMO, a series of bonds or certificates is issued in multiple classes.  Each
class  of CMO, also referred to as a "tranche," is issued at a specific fixed or
floating coupon  rate and  has a  stated maturity  or final  distribution  date.
Principal  prepayments  on the  Mortgage  Assets may  cause  CMOs to  be retired
substantially earlier than their stated maturities or final distribution  dates.
Interest is paid or accrues on all classes of a CMO (other than any PO class) on
a  monthly, quarterly  or semi-annual basis.  The principal and  interest on the
Mortgage Assets may  be allocated among  the several  classes of a  CMO in  many
ways.   In  one  structure,  payments  of  principal,  including  any  principal
prepayments, on the Mortgage Assets are applied  to the classes of a CMO in  the
order  of their respective stated maturities or final distribution dates so that
no payment of principal  will be made on  any class of the  CMO until all  other
classes  having an earlier stated maturity  or final distribution date have been
paid in  full.  In  some CMO  structures,  all  or a  portion  of  the  interest
attributable  to one or  more of the CMO  classes may be  added to the principal
amounts  attributable  to   such  classes,   rather  than   passed  through   to
certificateholders  on a current basis, until other  classes of the CMO are paid
in full.
 
Parallel pay  CMOs are  structured  to provide  payments  of principal  on  each
payment  date to more than one class. These simultaneous payments are taken into
account in calculating the  stated maturity date or  final distribution date  of
each  class, which, as with other CMO  structures, must be retired by its stated
maturity date or final distribution date but may be retired earlier.
 
Some CMO classes are structured  to pay interest at  rates that are adjusted  in
accordance  with a formula,  such as a multiple  or fraction of  the change in a
specified interest rate index, so as to pay at a rate that will be attractive in
certain interest rate environments  but not in others.  For example, an  inverse
floating  rate CMO class pays  interest at a rate  that increases as a specified
interest rate index decreases but decreases  as that index increases. For  other
CMO  classes, the yield may move in  the same direction as market interest rates
- -- i.e., the yield may increase as rates increase and decrease as rates decrease
- --

but may do  so more rapidly  or to a  greater degree. The  market value of  such
securities generally is more volatile than that of a fixed rate obligation. Such
interest  rate  formulas may  be combined  with  other CMO  characteristics. For
example, a CMO class may be an  "inverse IO," on which the holders are  entitled
to  receive no payments of  principal and are entitled  to receive interest at a
rate that will vary inversely with a specified index or a multiple thereof.
 
    ARM  AND  FLOATING  RATE  MORTGAGE-BACKED  SECURITIES.  ARM  mortgage-backed
securities  are  mortgage-backed securities  that represent  a right  to receive
interest payments at a rate that is adjusted to reflect the interest earned on a
pool of mortgage loans  bearing variable or adjustable  rates of interest  (such
mortgage  loans  are  referred  to  as  "ARMs").  Floating  rate mortgage-backed
securities are classes of mortgage-backed  securities that have been  structured
to  represent the right to receive interest  payments at rates that fluctuate in
accordance with an index but that generally are supported by pools comprised  of
fixed-rate  mortgage loans. Because the interest  rates on ARM and floating rate
mortgage-backed securities  are reset  in  response to  changes in  a  specified
market  index,  the values  of  such securities  tend  to be  less  sensitive to
interest rate fluctuations than the values of fixed-rate securities.
 
ARMs generally specify  that the borrower's  mortgage interest rate  may not  be
adjusted  above a  specified lifetime  maximum rate or,  in some  cases, below a
minimum lifetime rate. In addition, certain ARMs specify for limitations on  the
maximum  amount by which  the mortgage interest  rate may adjust  for any single
adjustment period. ARMs also  may limit changes in  the maximum amount by  which
the  borrower's monthly payment may adjust  for any single adjustment period. In
the event that a monthly payment is not sufficient to pay the interest  accruing
on  the ARM, any such  excess interest is added  to the mortgage loan ("negative
amortization"), which is repaid through future payments. If the monthly  payment
exceeds the sum of the interest accrued at the applicable mortgage interest rate
and  the  principal  payment that  would  have  been necessary  to  amortize the
outstanding principal balance over  the remaining term of  the loan, the  excess
reduces  the principal  balance of  the ARM.  Borrowers under  ARMs experiencing
negative amortization may take longer to build up their equity in the underlying
property and may be more likely to default interest. ARMs also may be subject to
a greater rate of prepayments in a declining interest rate environment.
 
The rates of interest payable on certain ARMs are based on indices, such as  the
one-year  constant  maturity  Treasury  rate,  that  reflect  changes  in market
interest rates. Others are based on indices  that tend to lag behind changes  in
market interest rates. The values of ARM mortgage-backed securities supported by
ARMs  that adjust based on lagging indices tend to be somewhat more sensitive to
interest rate fluctuations than those  reflecting current interest rate  levels,
although the value of such ARM mortgage-backed securities still tends to be less
sensitive to interest rate fluctuations than fixed-rate securities.
 
As  with ARM mortgage-backed  securities, interest rate  adjustments on floating
rate mortgage-backed securities may be based  on indices that lag behind  market
interest  rates.  Interest  rates on  floating  rate  mortgage-backed securities
generally are  adjusted monthly.  Floating rate  mortgage-backed securities  are
subject  to lifetime interest rate  caps, but they generally  are not subject to
limitations on monthly or  other periodic changes in  interest rates or  monthly
payments.
 
    TYPES OF CREDIT ENHANCEMENT. To lessen the effect of failures by obligors on
Mortgage  Assets  to  make  payments,  mortgage-backed  securities  may  contain
elements  of  credit  enhancement.  Such  credit  enhancement  falls  into   two
categories: (1) liquidity protection and (2) protection against losses resulting
after  default by  an obligor  on the  underlying assets  and collection  of all
amounts recoverable directly  from the  obligor and through  liquidation of  the
collateral.  Liquidity protection refers to the provision of advances, generally
by the  entity administering  the  pool of  assets  (usually the  bank,  savings
association  or mortgage  banker that  transferred the  underlying loans  to the
issuer of  the  security),  to  ensure  that the  receipt  of  payments  on  the
underlying  pool occurs in a timely fashion. Protection against losses resulting
after default and liquidation ensures ultimate payment of the obligations on  at
least  a portion  of the  assets in  the pool.  Such protection  may be provided
through guarantees,  insurance policies  or letters  of credit  obtained by  the
issuer  or sponsor, from third parties, through various means of structuring the
transaction or through a combination of such approaches. The Funds will not  pay
any  additional  fees for  such credit  enhancement,  although the  existence of
credit enhancement may increase the price of a security. Credit enhancements  do
not  provide protection  against changes  in the  market value  of the security.
Examples of credit enhancement arising out  of the structure of the  transaction
include  "senior-subordinated securities" (multiple class securities with one or
more classes subordinate to other classes as to the payment of principal thereof
and interest thereon, with the result that defaults on the underlying assets are
borne first  by the  holders of  the subordinated  class), creation  of  "spread
accounts" or "reserve funds" (where cash or investments, sometimes funded from a
portion  of the payments on  the underlying assets, are  held in reserve against
future losses) and "over-collateralization" (where the scheduled payments on, or
the principal amount  of, the  underlying assets  exceed that  required to  make
payment  of the securities and  pay any servicing or  other fees). The degree of
credit enhancement provided for each issue generally is

based on historical information  regarding the level  of credit risk  associated
with  the underlying assets.  Delinquency or loss in  excess of that anticipated
could adversely affect the return on an investment in such a security.
 
VARIABLE AND FLOATING RATE SECURITIES
The Money Market Fund  may purchase variable and  floating rate securities  with
remaining  maturities in excess  of 13 months. Such  securities must comply with
conditions established by  the Securities  and Exchange  Commission (the  "SEC")
under  which they may be considered to have remaining maturities of 13 months or
less. The yield of  these securities varies in  relation to changes in  specific
money  market  rates such  as the  prime  rate. These  changes are  reflected in
adjustments to the  yields of  the variable  and floating  rate securities,  and
different securities may have different adjustment rates. To the extent that the
Money  Market Fund invests in such variable  and floating rate securities, it is
the Sub-advisor's view that the Money Market Fund may be able to take  advantage
of  the  higher  yield  that  is usually  paid  on  longer-term  securities. The
Sub-advisor further believes that the variable  and floating rates paid on  such
securities may substantially reduce the wide fluctuations in market value caused
by interest rate changes and other factors which are typical of longer-term debt
securities.
 
INDEXED SECURITIES.
The  Strategic Income  Fund may  invest without  limitation in  commercial paper
which is indexed to certain specific foreign currency exchange rates. The  terms
of  such commercial paper provide that  its principal amount is adjusted upwards
or downwards (but not below zero) at maturity to reflect changes in the exchange
rate between two currencies while the  obligation is outstanding. The Fund  will
purchase such commercial paper with the currency in which it is denominated and,
at  maturity,  will  receive interest  and  principal payments  thereon  in that
currency, but the  amount of principal  payable by the  issuer at maturity  will
change in proportion to the change (if any) in the exchange rate between the two
specified  currencies between the date the instrument is issued and the date the
instrument matures. While  such commercial  paper entails  the risk  of loss  of
principal,  the potential for realizing gains as  a result of changes in foreign
currency  exchange  rates  enables  the  Strategic  Income  Fund  to  hedge  (or
cross-hedge)  against  a  decline  in  the  U.S.  dollar  value  of  investments
denominated in foreign currencies while  seeking to provide an attractive  money
market  rate  of  return.  The  Strategic Income  Fund  will  not  purchase such
commercial paper for speculation.
 
The Strategic Income Fund  and the Global Government  Income Fund may invest  in
certain  other indexed securities, which are securities whose prices are indexed
to the  prices of  other securities,  securities indices,  currencies,  precious
metals  or other commodities, or  other financial indicators. Indexed securities
typically, but  not always,  are  debt securities  or  deposits whose  value  at
maturity  or coupon rate is determined by  reference to a specific instrument or
statistic. The performance of  indexed securities depends to  a great extent  on
the  performance of the security, currency or other instrument to which they are
indexed, and  may also  be influenced  by interest  rate changes  in the  United
States  and abroad.  At the  same time,  indexed securities  are subject  to the
credit risks associated with  the issuer of the  security, and their values  may
decline  substantially  if the  issuer's creditworthiness  deteriorates. Indexed
securities may be more  volatile than the underlying  instruments. New forms  of
indexed  securities continue to be developed.  The Strategic Income Fund and the
Global Government  Income Fund  may  invest in  such  securities to  the  extent
consistent with its investment objectives.
 
DEPOSITORY RECEIPTS
Each  Fund, except  for the Global  Government Income Fund,  the U.S. Government
Income Fund and the Money Market Fund, may hold securities of foreign issuers in

("ADSs"),  Global Depository Receipts ("GDRs")  and European Depository Receipts
("EDRs") or other  securities convertible into  securities of eligible  issuers.
These  securities may not necessarily be denominated in the same currency as the
securities for which they may be  exchanged. ADRs and ADSs are typically  issued
by  an American  bank or  trust company  that evidences  ownership of underlying
securities issued by a foreign  corporation. EDRs, which are sometimes  referred
to  as Continental Depository Receipts ("CDRs"),  are receipts issued in Europe,
typically by foreign banks and trust companies that evidence ownership of either
foreign or domestic securities. Generally, ADRs and ADSs in registered form  are
designed for use in U.S. securities markets and EDRs in bearer form are designed
for  use in European  securities markets. For purposes  of the Funds' respective
investment policies, the Funds' investments in ADRs, ADSs, GDRs and EDRs will be
deemed to be  investments in  the equity securities  representing securities  of
foreign issuers into which they may be converted.
 
ADR  facilities may be established as either "unsponsored" or "sponsored." While
ADRs issued under these  two types of facilities  are in some respects  similar,
there  are distinctions between  them relating to the  rights and obligations of
ADR holders and the practices of market participants. A depository may establish
an unsponsored  facility  without  participation by  (or  even  necessarily  the
acquiescence  of) the issuer of the deposited securities, although typically the
depository
 
                  Statement of Additional Information Page 12
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
requests a letter of non-objection from  such issuer prior to the  establishment
of  the facility. Holders  of unsponsored ADRs  generally bear all  the costs of
such facilities.  The  depository usually  charges  fees upon  the  deposit  and
withdrawal  of the deposited  securities, the conversion  of dividends into U.S.
dollars, the disposition of non-cash distributions, and the performance of other
services. The  depository of  an  unsponsored facility  frequently is  under  no
obligation  to distribute shareholder communications received from the issuer of
the deposited securities or  to pass through voting  rights to ADR holders  with
respect  to the  deposited securities. Sponsored  ADR facilities  are created in
generally the same manner as unsponsored  facilities, except that the issuer  of
the  deposited securities enters  into a deposit  agreement with the depository.
The deposit agreement sets  out the rights and  responsibilities of the  issuer,
the depository and the ADR holders. With sponsored facilities, the issuer of the
deposited  securities  generally will  bear some  of the  costs relating  to the
facility (such as dividend payment fees of the depository), although ADR holders
continue to bear  certain other  costs (such  as deposit  and withdrawal  fees).
Under the terms of most sponsored arrangements, depositories agree to distribute
notices  of  shareholder  meetings  and  voting  instructions,  and  to  provide
shareholder communications  and other  information  to the  ADR holders  at  the
request  of the  issuer of  the deposited  securities. The  Funds may  invest in
sponsored and unsponsored ADRs.
 
BRADY BONDS.
The Latin America  Fund, the Global  Government Income Fund,  and the  Strategic
Income  Fund may  invest in  "Brady Bonds,"  which are  debt restructurings that
provide for the exchange of cash and  loans for newly issued bonds. Brady  Bonds
have been issued by the countries of Albania, Argentina, Brazil, Bulgaria, Costa
Rica, Dominican Republic, Ecuador, Ivory Coast, Jordan, Mexico, Nigeria, Panama,
Peru,  Philippines,  Poland, Russia,  Uruguay,  Venezuela and  Vietnam,  and are
expected to be issued by other emerging market countries. As of the date of this
Statement of Additional Information, the Funds  are not aware of the  occurrence
of  any payment  defaults on Brady  Bonds. Investors  should recognize, however,
that Brady Bonds do not  have a long payment  history. In addition, Brady  Bonds
are often rated below investment grade.
 
The  Latin America  Fund, the Global  Government Income Fund,  and the Strategic
Income Fund may invest in either collateralized or uncollateralized Brady Bonds.
U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed rate par
bonds or  floating  rate  discount  bonds, are  collateralized  in  full  as  to
principal  by U.S. Treasury  zero coupon bonds  having the same  maturity as the
bonds. Interest payments on such bonds  generally are collateralized by cash  or
securities  in an amount that, in  the case of fixed rate  bonds, is equal to at
least one year  of rolling interest  payments based on  the applicable  interest
rate at the time of issuance and is adjusted at regular intervals thereafter.
 
SAMURAI AND YANKEE BONDS
The New Pacific Fund, the International Fund, the Strategic Income Fund, and the
Global  Government Income Fund may invest in yen-denominated bonds sold in Japan
by non-Japanese issuers ("Samurai bonds"),  and the America Fund, the  Strategic
Income   Fund  and  the  Global  Government  Income  Fund  may  invest  in  U.S.
dollar-denominated bonds sold in the United States by non-U.S. issuers  ("Yankee
bonds").  It is  the policy  of each Fund  to invest  in Samurai  or Yankee bond
issues only after taking into  account considerations of quality and  liquidity,
as well as yield.
 
WARRANTS OR RIGHTS
Warrants  or rights may  be acquired by  the Funds, except  for the Money Market
Fund, in connection  with other securities  or separately, and  may provide  the
Funds with the right to purchase at a later date other securities of the issuer.
 
LENDING OF SECURITIES
For  the purpose  of realizing  additional income,  each Fund,  except the Money
Market Fund, may make secured loans of securities held by that Fund which amount
to not more than 30% of its total assets. Securities lending allows the Funds to
retain ownership of the securities loaned  and, at the same time, enhances  each
Fund's  total return.  While a loan  is outstanding, the  borrower must maintain
with  a  Fund's  custodian  collateral  consisting  of  cash,  U.S.   government
securities  or certain irrevocable letters of credit equal to at least the value
of the borrowed securities, plus any  accrued interest or such other  collateral
as  permitted by the  Fund's investment program and  regulatory agencies, and as
approved by the Board. The risks in lending portfolio securities, as with  other
extensions of secured credit, consist of possible delays in receiving additional
collateral  or in recovery of the loaned  securities and possible loss of rights
in the collateral  should the  borrower fail financially.  Securities loans  are
made  to  broker-dealers  or  institutional  investors  pursuant  to  agreements
requiring that the loans continuously be secured by collateral at least equal at
all times to the value of the securities lent plus any accrued interest, "marked
to market" on  a daily basis.  Each Fund may  pay reasonable administrative  and
custodial  fees in connection with loans of its securities. While the securities
loan is outstanding,  the Fund will  continue to receive  the equivalent of  the
interest  or dividends paid by the issuer on the securities, as well as interest
on the investment of the collateral or a  fee from the borrower. The Fund has  a
right   to   call   each   loan   and   obtain   the   securities   within   the
 
                  Statement of Additional Information Page 13
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
stated settlement  period. The  Fund will  not  have the  right to  vote  equity
securities  while they are being lent, but it may call in a loan in anticipation
of any important vote. Loans will be made only to firms deemed by AIM and/or the
sub-advisors to be of good standing and will not be made unless, in the judgment
of AIM and/or the sub-advisors, the  consideration to be earned from such  loans
would justify the risk.
 
COMMERCIAL BANK OBLIGATIONS
For  the purposes  of the Funds'  respective investment  policies regarding bank
obligations, obligations of foreign branches of U.S. banks and of foreign  banks
are obligations of the issuing bank and may be general obligations of the parent
bank.  Such obligations  may, however,  be limited  by the  terms of  a specific
obligation  and  by  government  regulation.  As  with  investment  in  non-U.S.
securities  in general,  investments in the  obligations of  foreign branches of
U.S. banks and of foreign banks may subject a Fund to investment risks that  are
different  in some respects from those of investments in obligations of domestic
issuers. Although a Fund typically will acquire obligations issued and supported
by the  credit of  U.S. or  foreign banks  having total  assets at  the time  of
purchase  in excess of $1  billion, this $1 billion  figure is not a fundamental
investment policy or restriction of such Fund. For purposes of calculation  with
respect to the $1 billion figure, the assets of a bank will be deemed to include
the assets of its U.S. and non-U.S. branches.
 
COMMERCIAL PAPER
U.S.  Government Income Fund  may invest in commercial  paper, which consists of
short-term promissory notes  issued by  large corporations with  a high  quality
rating to finance short-term credit needs.
 
REPURCHASE AGREEMENTS
A  repurchase agreement is  a transaction in  which a Fund  purchases a security
from a bank or recognized securities dealer and simultaneously commits to resell
that security to the  bank or dealer  at an agreed-upon  price, date and  market
rate  of interest  unrelated to  the coupon  rate or  maturity of  the purchased
security.
 
Although repurchase agreements  carry certain risks  not associated with  direct
investments in securities, including possible decline in the market value of the
underlying securities and delays and costs to the Fund if the other party to the
repurchase  agreement  becomes bankrupt,  the Funds  will enter  into repurchase
agreements only with banks and dealers  believed by AIM and/or the  sub-advisors
to  present minimal credit  risks in accordance with  guidelines approved by the
Companies' Boards  of Trustees.  AIM  and/or the  sub-advisors will  review  and
monitor  the  creditworthiness of  such institutions  under the  Boards' general
supervision.
 
Each Fund will invest only in repurchase agreements collateralized at all  times
in  an amount at least  equal to the repurchase  price plus accrued interest. To
the extent that the proceeds  from any sale of  such collateral upon default  in
the obligation to repurchase were less than the repurchase price, the Fund would
suffer  a loss. If  the financial institution  which is party  to the repurchase
agreement petitions for bankruptcy or otherwise becomes subject to bankruptcy or
other liquidation proceedings, there may  be restrictions on the Fund's  ability
to  sell the collateral and the Fund  could suffer a loss. However, with respect
to financial  institutions  whose  bankruptcy  or  liquidation  proceedings  are
subject  to the U.S. Bankruptcy Code, the Fund intends to comply with provisions
under the U.S.  Bankruptcy Code that  would allow it  immediately to resell  the
collateral.  There is  no limitation  on the  amount of  the Fund  assets may be
subject to repurchase agreements at  any given time. No  Fund will enter into  a
repurchase  agreement with a  maturity of more  than seven days  if, as a result
more than 15% (10%  for the Money Market  Fund) of the value  of its net  assets
would be invested in such repurchase agreements and other illiquid investments.
 
BORROWING, REVERSE REPURCHASE AGREEMENTS AND "ROLL" TRANSACTIONS
 
BORROWING AND LENDING.
From time to time, it may be advantageous for a Fund to borrow money rather than
sell  existing securities to  meet redemption requests.  Accordingly, a Fund may
borrow from  banks or  (except for  the Money  Market Fund)  may borrow  through
reverse repurchase agreements and "roll" transactions in connection with meeting
requests  for the redemption  of shares of  the Fund. The  Funds (except for the
Infrastructure Fund, the  Natural Resources Fund,  the Telecommunications  Fund,
the  Emerging  Markets  Fund  and  the Latin  America  Fund)  will  not purchase
securities while  borrowings  are  outstanding.  The  Infrastructure  Fund,  the
Natural  Resources Fund, the Telecommunications  Fund, the Emerging Markets Fund
and the  Latin  America  Fund  may  each  purchase  additional  securities  when
outstanding borrowings represent no more than 5% of its assets.
 
Each Fund's borrowings will not exceed 33 1/3% of the Fund's total assets, i.e.,
the  Fund's total assets at all times will  equal at least 300% of the amount of
outstanding  borrowing.  If  market  fluctuations  in  the  value  of  a  Fund's
securities  holdings or other factors cause the ratio of the Fund's total assets
to outstanding  borrowings to  fall  below 300%,  within three  days  (excluding
Sundays  and holidays) of such event the Fund may be required to sell securities
to restore the 300% asset
 
                  Statement of Additional Information Page 14
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
coverage, even  though  from  an  investment  standpoint  such  sales  might  be
disadvantageous.  Each Fund  also may borrow  up to  5% of its  total assets for
temporary or emergency purposes other than  to provide cash to meet  redemptions
of Fund shares. Any borrowing by a Fund may cause greater fluctuation in its net
asset value than would be the case if the Fund did not borrow.
 
Each  Fund  (except  the Strategic  Income  Fund) currently  is  prohibited from
borrowing money  in order  to purchase  securities. If  a Fund  is permitted  to
employ  leverage in the future, it would be subject to certain additional risks.
Use of leverage creates an opportunity  for greater growth of capital but  would
exaggerate  any increases or decreases  in the Fund's net  asset value. When the
income and gains on securities purchased with the proceeds of borrowings  exceed
the  costs  of such  borrowings, the  Fund's  earnings or  net asset  value will
increase faster than otherwise would be the case; conversely if such income  and
gains  fail to exceed such  costs, the Fund's earnings  or net asset value would
decline faster than would otherwise be the case.
 
Excluding the Money  Market Fund, each  Fund may enter  into reverse  repurchase
agreements. A reverse repurchase agreement is a borrowing transaction in which a
Fund  transfers possession  of a security  to another  party, such as  a bank or
broker/dealer in return for cash, and  agrees to repurchase the security in  the
future  at an agreed  upon price, which includes  an interest component. Reverse
repurchase agreements involve the risk that  the market value of the  securities
retained in lieu of sale by a Fund may decline below the price of the securities
the  Fund had  sold but is  obligated to repurchase.  In the event  the buyer of
securities under a reverse repurchase agreement files for bankruptcy or  becomes
insolvent,  such buyer or  its trustee or  receiver may receive  an extension of
time to determine  whether to enforce  the Fund's obligation  to repurchase  the
securities,  and  the  Fund's use  of  the  proceeds of  the  reverse repurchase
agreement may effectively be restricted pending such decision.
 
The Funds (except for the Money Market Fund) also may engage in "roll" borrowing
transactions, which involve the  sale of GNMA  certificates or other  securities
together  with a  commitment (for which  a Fund  may receive a  fee) to purchase
similar, but not  identical, securities  at a future  date. Each  Fund will  set
aside cash or liquid securities in an amount sufficient to cover its obligations
under "roll" transactions and reverse repurchase agreements with broker/dealers.
No segregation is required for reverse repurchase agreements with banks.
 
The Strategic Income Fund may borrow money from banks in an amount up to 33 1/3%
of  its total assets  (including the amount borrowed),  less all liabilities and
indebtedness other  than  the  borrowing  and  may  use  the  proceeds  of  such
borrowings  for investment purposes.  The Strategic Income  Fund will borrow for
investment purposes only when the Sub-advisor believes that such borrowings will
benefit the Strategic Income Fund, after taking into account considerations such
as the  costs  of  the  borrowing  and the  likely  investment  returns  on  the
securities purchased with the borrowed monies.
 
Borrowing for investment purposes is known as leveraging, which is a speculative
practice. Such borrowing by the Strategic Income Fund will create an opportunity
for  increased  net  income  but,  at  the  same  time,  involves  special  risk
considerations. For  example, leveraging  might exaggerate  changes in  the  net
asset  value of the Strategic Income Fund's  shares and in the yield realized by
the Fund's portfolio. Although the principal  of such borrowings will be  fixed,
the  Strategic Income  Fund's assets  may change  in value  during the  time the
borrowing is outstanding. By leveraging the  Fund, changes in net asset  values,
higher  or lower, may be greater in degree than if leverage was not employed. To
the extent  the income  derived from  the assets  obtained with  borrowed  funds
exceeds the interest and other expenses that the Strategic Income Fund will have
to  pay, the Fund's net income will be  greater than if borrowing were not used.
Conversely, if the income  from the assets obtained  with borrowed funds is  not
sufficient  to cover  the cost  of borrowing,  the net  income of  the Strategic
Income Fund will  be less than  if borrowing  were not used,  and therefore  the
amount available for distribution to shareholders as a dividend will be reduced.
The  Strategic Income Fund expects that some of  its borrowings may be made on a
secured basis.
 
The Strategic Income Fund also may enter into "dollar rolls," in which the  Fund
sells   fixed  income  securities  for  delivery   in  the  current  month,  and
simultaneously contracts to repurchase substantially similar (same type,  coupon
and maturity) securities on a specified future date. During the roll period, the
Strategic  Income  Fund  would  forego  principal  and  interest  paid  on  such
securities. The Strategic  Income Fund  would be compensated  by the  difference
between  the current sales price and the  forward price for the future purchase,
as well as by the interest earned on the cash proceeds of the initial sale.
 
SHORT SALES
The Funds may  make short  sales of securities,  although they  have no  current
intention   of  doing  so.  However,  Growth   &  Income  Fund,  pursuant  to  a
non-fundamental limitation, may not sell securities short, except to the  extent
the  Fund contemporaneously owns  or has the  right to acquire  at no additional
cost securities identical to those sold short. A short sale is a transaction  in
which  a Fund  sells a security  in anticipation  that the market  price of that
security will decline. A Fund
 
                  Statement of Additional Information Page 15
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
may make short sales (i)  as a form of hedging  to offset potential declines  in
long  positions in securities  it owns, or anticipates  acquiring, or in similar
securities, and (ii) in  order to maintain investment  flexibility. When a  Fund
makes  a short sale of a  security it does not own,  it must borrow the security
sold short and  deliver it to  the broker/dealer or  other intermediary  through
which  it  made the  short  sale. The  Fund  may have  to  pay a  fee  to borrow
particular securities  and will  often be  obligated to  pay over  any  payments
received on such borrowed securities.
 
The  Fund's obligation  to replace the  borrowed security when  the borrowing is
called or expires will be secured by collateral deposited with the intermediary.
The Fund also will be required to  deposit collateral with its custodian to  the
extent  necessary so that the value of both collateral deposits in the aggregate
is at all  times equal  to at  least 100%  of the  current market  value of  the
security  sold short. Depending on arrangements  made with the intermediary from
which it borrowed the security, regarding payment of any amounts received by the
Fund on  such  security,  the  Fund may  not  receive  any  payments  (including
interest) on its collateral deposited with such intermediary.
 
If  the price of the security sold short increases between the time of the short
sale and the time the Fund replaces the borrowed security, the Fund will incur a
loss; conversely, if the price declines, the Fund will realize a gain. Any  gain
will  be decreased, and any loss  increased, by the transaction costs associated
with the transaction. Although the Fund's gain is limited by the price at  which
it sold the security short, its potential loss theoretically is unlimited.
 
The  Infrastructure  Fund, the  Natural  Resources Fund,  the Telecommunications
Fund, the Emerging  Markets Fund, and  the Latin  America Fund will  not make  a
short  sale  if, after  giving  effect to  such sale,  the  market value  of the
securities sold short exceeds 25% of the value of their respective total assets,
or their respective aggregate  short sales of the  securities of any one  issuer
exceed  the lesser of 2% of  net assets or 2% of  the securities of any class of
the issuer. Moreover, the Infrastructure  Fund, the Natural Resources Fund,  the
Telecommunications  Fund and  the Latin America  Fund may engage  in short sales
only with respect to securities listed on a national securities exchange.
 
A Fund might  make a  short sale  "against the box"  in order  to hedge  against
market  risks when  the Sub-advisor  believes that the  price of  a security may
decline, causing a decline  in the value of  a security owned by  the Fund or  a
security  convertible into or exchangeable for  such security. In such case, any
future losses in the  Fund's long position  should be reduced by  a gain in  the
short position. Conversely, any gain in the long position should be reduced by a
loss in the short position. The extent to which such gains or losses in the long
position  are reduced will depend  upon the amount of  the securities sold short
relative to  the amount  of the  securities the  Fund owns,  either directly  or
indirectly, and, in the case where the Fund owns convertible securities, changes
in  the investment values or conversion  premiums of such securities. There will
be certain additional transaction costs associated with short sales "against the
box," but the Funds  will endeavor to  offset these costs  with income from  the
investment of the cash proceeds of short sales.
 
TEMPORARY DEFENSIVE STRATEGIES
The  Emerging  Markets Fund  and Latin  America  Growth Fund  may invest  in the
following types of money  market instruments (I.E.,  debt instruments with  less
than  12 months remaining  until maturity) denominated in  U.S. dollars or other
currencies (in  the  case  of  Latin  America  Growth  Fund,  a  Latin  American
currency):  (a)  obligations  issued  or  guaranteed  by  the  U.S.  or  foreign
governments (in the case of Latin America Growth Fund, the government of a Latin
American country),  their  agencies, instrumentalities  or  municipalities;  (b)
obligations  of international  organizations designed  or supported  by multiple
foreign governmental entities to promote economic reconstruction or development;
(c) finance company obligations, corporate commercial paper and other short-term
commercial obligations; (d) bank obligations (including certificates of deposit,
time  deposits,  demand  deposits  and  bankers'  acceptances);  (e)  repurchase
agreements  with respect to  the foregoing; and  (f) other substantially similar
short-term debt securities with comparable characteristics.
 
The Emerging Markets Fund and Latin America Growth Fund may invest in commercial
paper rated as low as A-3 by S&P or P-3 by Moody's or, if not rated,  determined
by  AIM and/or the  Fund's sub-advisor to be  of comparable quality. Obligations
rated A-3 and P-3 are  considered by S&P and  Moody's, respectively, to have  an
acceptable  capacity for timely repayment. However, these securities may be more
vulnerable to  adverse  effects of  changes  in circumstances  than  obligations
carrying higher designations.
 
INVESTMENT IN OTHER INVESTMENT COMPANIES OR VEHICLES.
Each  Fund may invest in the securities of other investment companies within the
limits of the 1940  Act. The Funds  may be able to  invest in certain  countries
solely  or primarily  through governmentally  authorized investment  vehicles or
companies. Each Fund may invest up to  10% of its total assets in the  aggregate
in  shares of other investment companies and up to 5% of its total assets in any
one investment company, as long as each investment does not represent more  than
3% of the
 
                  Statement of Additional Information Page 16
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
voting  stock of the acquired investment company at the time of investment. Some
of the investment companies in which the Funds invest may be investment vehicles
or companies that are advised by AIM and/or the sub-advisors.
 
Investment in other investment companies may involve the payment of  substantial
premiums  above the value of such investment companies' portfolio securities and
is subject to limitations under the 1940 Act and market availability. The  Funds
do  not intend to invest in investment  companies unless, in the judgment of AIM
and/or the sub-advisors, the potential  benefits of such investment justify  the
payment  of  any applicable  premium or  sales  charge. As  a shareholder  in an
investment company,  a Fund  would bear  its ratable  share of  that  investment
company's  expenses, including its advisory and administration fees. At the same
time, a Fund would continue  to pay its own  management fees and other  expenses
except  with  respect  to investments  in  other investment  companies  that are
advised by AIM and/or the sub-advisors. AIM and/or the sub-advisors have  agreed
to  waive  its  fees to  the  extent that  such  fees  are based  on  the Funds'
investments in such other investment companies.
 
LOAN PARTICIPATIONS AND ASSIGNMENTS.
The Strategic Income Fund may invest in fixed and floating rate loans  ("Loans")
arranged  through private negotiations between a  foreign entity and one or more
financial institutions ("Lenders"). The majority of the Strategic Income  Fund's
investments  in  Loans in  emerging markets  is expected  to be  in the  form of
participations in Loans ("Participations") and assignments of portions of  Loans
from  third parties ("Assignments"). Participations typically will result in the
Strategic Income Fund's having a contractual relationship only with the  Lender,
not  with the borrower government. The Strategic Income Fund will have the right
to receive payments of principal, interest and any fees to which it is  entitled
only  from the  Lender selling  the Participation and  only upon  receipt by the
Lender of  the  payments  from  the  borrower.  In  connection  with  purchasing
Participations,  the  Strategic  Income Fund  generally  will have  no  right to
enforce compliance by the borrower with the terms of the loan agreement relating
to the loan ("Loan Agreement"), nor any rights of set-off against the  borrower,
and the Fund may not directly benefit from any collateral supporting the Loan in
which it has purchased the Participation. As a result, the Strategic Income Fund
will  assume the credit risk of both the borrower and the Lender that is selling
the Participation.
 
In the  event of  the insolvency  of  the Lender  selling a  Participation,  the
Strategic Income Fund may be treated as a general creditor of the Lender and may
not  benefit from any set-off between the Lender and the borrower. The Strategic
Income Fund  will  acquire Participations  only  if the  Lender  interpositioned
between  the  Fund and  the  borrower is  determined  by the  Sub-advisor  to be
creditworthy. When the Strategic Income Fund purchases Assignments from Lenders,
the Fund will acquire direct rights  against the borrower on the Loan.  However,
since  Assignments are  arranged through private  negotiations between potential
assignees and potential assignors,  the rights and  obligations acquired by  the
Strategic  Income Fund as the purchaser of an Assignment may differ from, and be
more limited than, those held by the assigning Lender.
 
PRIVATIZATIONS.
The governments  of some  foreign countries  have been  engaged in  programs  of
selling  part  or  all  of  their  stakes  in  government  owned  or  controlled
enterprises  ("privatizations").  AIM  and/or  the  sub-advisors  believe   that
privatizations  may offer opportunities for significant capital appreciation and
intend to invest assets of the Infrastructure Fund, the Natural Resources  Fund,
the  Telecommunications Fund, the  Emerging Markets Fund,  and the Latin America
Fund, respectively, in privatizations  in appropriate circumstances. In  certain
foreign  countries,  the  ability  of  foreign entities  such  as  the  Funds to
participate in privatizations may be limited by local law, or the terms on which
the Funds may be  permitted to participate may  be less advantageous than  those
for  local investors.  There can be  no assurance that  foreign governments will
continue to  sell  companies currently  owned  or  controlled by  them  or  that
privatization programs will be successful.
 
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES.
The Funds may purchase debt securities on a "when-issued" basis and may purchase
or  sell  such securities  on a  "forward  commitment" basis  in order  to hedge
against anticipated changes in  interest rates and prices.  The price, which  is
generally expressed in yield terms, is fixed at the time the commitment is made,
but  delivery  and  payment for  the  securities  take place  at  a  later date.
When-issued securities  and  forward  commitments  may  be  sold  prior  to  the
settlement  date, but  a Fund  will purchase  or sell  when-issued securities or
enter into forward commitments only with the intention of actually receiving  or
delivering  the securities, as the case may  be. No income accrues on securities
that have been purchased  pursuant to a forward  commitment or on a  when-issued
basis  prior to delivery to the Fund. If a Fund disposes of the right to acquire
a when-issued security  prior to  its acquisition or  disposes of  its right  to
deliver or receive against a forward commitment, it may incur a gain or loss. At
the time a Fund enters into a transaction on a when-issued or forward commitment
basis,  the Fund will segregate cash or  liquid securities equal to the value of
the when-issued or forward
 
                  Statement of Additional Information Page 17
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
commitment securities with  its custodian  and will  mark to  market daily  such
assets.  There is a risk  that the securities may not  be delivered and that the
Fund may incur a loss. The Growth and  Income Fund will not invest more than  5%
of its assets in a combination of securities purchased on a when-issued basis or
with respect to which it has entered into forward commitment agreements.
 
The Strategic Income Fund may also sell securities on a "when, as and if issued"
basis  for hedging purposes. Under such a transaction, the Strategic Income Fund
is required to deliver at a future  date a security it does not presently  hold,
but  which it has a right to receive  if the security is issued. Issuance of the
security may not occur, in  which case the Strategic  Income Fund would have  no
obligation  to  the other  party and  would  not receive  payment for  the sale.
Selling securities on a "when, as and  if issued" basis may reduce risk of  loss
to  the extent that  such a sale  wholly or partially  offsets unfavorable price
movements on the investments  being hedged. However, such  sales also limit  the
amount  the Strategic Income  Fund can receive  if the "when,  as and if issued"
security is in fact issued.
 
ZERO COUPON SECURITIES.
The Strategic  Income Fund,  the Global  Government Income  Fund, and  the  U.S.
Government  Income Fund  may invest in  certain zero coupon  securities that are
"stripped" U.S. Treasury  notes and bonds.  The Strategic Income  Fund also  may
invest  in  zero coupon  and other  deep discount  securities issued  by foreign
governments and domestic and foreign corporations, including certain Brady Bonds
and other foreign debt securities and in payment-in-kind securities. Zero coupon
securities pay no  interest to  holders prior to  maturity, and  payment-in-kind
securities pay interest in the form of additional securities. However, a portion
of  the original issue discount on zero  coupon securities and the "interest" on
payment-in-kind  securities  are  included  in  the  investing  Fund's   income.
Accordingly,  to continue to qualify for tax treatment as a regulated investment
company and to avoid  a certain excise tax  (see "Taxes", below), the  Strategic
Income  Fund or the U.S. Government Income Fund may be required to distribute an
amount that is greater than the total amount of cash it actually receives. These
distributions must  be  made from  the  Funds'  respective cash  assets  or,  if
necessary,  from the  proceeds of sales  of portfolio  securities. The Strategic
Income Fund and the  U.S. Government Income  Fund will not  be able to  purchase
additional   income-producing   securities   with  cash   used   to   make  such
distributions, and their respective current incomes ultimately may be reduced as
a result. Zero  coupon and payment-in-kind  securities usually trade  at a  deep
discount from their face or par value and are subject to greater fluctuations of
market value in response to changing interest rates than are debt obligations of
comparable maturities that make current distributions of interest in cash.
 
OTHER INFORMATION.
The investment objective(s) of each Fund may not be changed without the approval
of  a majority of the outstanding voting securities of such Fund. A "majority of
the outstanding voting securities"  of a Fund  means the lesser  of: (i) 67%  or
more  of the  shares represented  at a  meeting at  which more  than 50%  of the
outstanding shares are  represented, or (ii)  more than 50%  of the  outstanding
shares.  In addition, each Fund has  adopted certain investment limitations that
may not be changed without shareholder approval. A complete description of these
limitations is included below (see "Investment Limitations"). Each Fund's  other
investment  policies described herein may be changed by the Board of Trustees of
the relevant Company, without shareholder approval.
 
If a  percentage  restriction on  investment  or  utilization of  assets  in  an
investment  policy or  restriction is  adhered to at  the time  an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market  values or a  similar type of  event will not  be
considered a violation of a Fund's investment policies or restrictions.
 
Certain  of the  Funds are  authorized to engage  in Short  Sales, although they
currently have no intention of doing so, and certain Funds may purchase American
Depository Receipts, American Depository Shares, Global Depository Receipts  and
European  Depository  Receipts.  See "Short  Sales"  and  "Depository Receipts",
above.

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
Each  Fund (except  the Money Market  Fund) may use  forward currency contracts,
futures contracts,  options  on  securities,  options  on  indices,  options  on
currencies  and options  on futures  contracts to  attempt to  hedge against the
overall level of investment and currency risk normally associated with the Fund.
These instruments are often referred to  as "derivatives," which may be  defined
as  financial instruments whose  performance is derived, at  least in part, from
the performance of another asset (such as  a security, currency, or an index  of
securities).  The Funds may enter into such  investments up to the full value of
their portfolio assets.
 
To attempt to increase  return, the Growth &  Income Fund, the Strategic  Income
Fund,  the Global Government Income Fund and the U.S. Government Income Fund may
write call options on securities. This  strategy will be employed only when,  in
the  opinion of AIM  and/or the sub-advisors,  the size of  the premium the Fund
receives for writing the option is  adequate to compensate the Fund against  the
risk  that appreciation in the underlying security  may not be fully realized if
the option is exercised.  Each of these  Funds is also  authorized to write  put
options  to  attempt to  enhance return,  although they  don't have  the current
intention of so doing.
 
To attempt  to  hedge  against  adverse  movements  in  exchange  rates  between
currencies,  each Fund  (except the  Money Market  Fund) may  enter into forward
currency contracts  for  the purchase  or  sale of  a  specified currency  at  a
specified  future date.  Such contracts  may involve the  purchase or  sale of a
foreign currency against the U.S. dollar or may involve two foreign  currencies.
Each  such Fund may enter into forward currency contracts either with respect to
specific transactions or with respect  to that Fund's portfolio positions.  Each
Fund  also may  purchase and sell  put and  call options on  currencies to hedge
against movements in exchange rates.
 
In addition, each Fund (except the Money Market Fund) may purchase and sell  put
and  call options  on equity and  debt securities  to hedge against  the risk of
fluctuations in the prices of securities held by the Fund or that AIM and/or the
Fund's sub-advisor intends to include in  the Fund's portfolio. Each such  Fund,
except  for the Strategic Income Fund, the Global Government Income Fund and the
U.S. Government Income Fund, also may purchase and sell put and call options  on
stock  indexes to hedge  against overall fluctuations  in the securities markets
generally or in a specific market sector.
 
Further, each  Fund (except  the Strategic  Income Fund,  the Global  Government
Income Fund, the U.S. Government Income Fund and the Money Market Fund) may sell
stock index futures contracts and may purchase put options or write call options
on such futures contracts to protect against a general stock market decline or a
decline  in  a specific  market sector  that could  affect adversely  the Fund's
holdings. Such  Funds  also  may  purchase stock  index  futures  contracts  and
purchase  call options or write put options on such contracts to hedge against a
general stock market or market sector advance and thereby attempt to lessen  the
cost of future securities acquisitions. Each Fund (except the Money Market Fund)
may  use interest rate futures  contracts and options thereon  to hedge the debt
portion of its portfolio against changes in the general level of interest rates.
 
These practices may result in the loss of principal under certain conditions. In
addition, certain provisions of  the Internal Revenue Code  of 1986, as  amended
(the  "Code"), have  the effect of  limiting the  extent to which  the Funds may
enter  into  forward  contracts  or  futures  contracts  or  engage  in  options
transactions. See "Taxes", above.
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The  use of options, futures contracts  and forward currency contracts ("Forward
Contracts") involves special considerations and risks, as described below. Risks
pertaining to particular instruments are described in the sections that follow.
 
        (1) Successful  use  of  most  of these  instruments  depends  upon  the
    Sub-advisor's  ability to  predict movements  of the  overall securities and
    currency markets, which requires different skills than predicting changes in
    the prices of individual securities. While the Sub-advisor is experienced in
    the use of these instruments, there can be no assurance that any  particular
    strategy adopted will succeed.
 
        (2)  There  might  be  imperfect correlation,  or  even  no correlation,
    between price  movements  of  an  instrument  and  price  movements  of  the
    investments being hedged. For example, if the value of an instrument used in
    a  short hedge  increased by less  than the  decline in value  of the hedged
    investment, the hedge would not be fully successful.
 
                  Statement of Additional Information Page 19
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
    Such a lack of correlation might occur due to factors unrelated to the value
    of the investments being hedged, such  as speculative or other pressures  on
    the  markets in which the hedging instrument is traded. The effectiveness of
    hedges using hedging  instruments on indices  will depend on  the degree  of
    correlation  between price movements in the index and price movements in the
    investments being hedged.
 
        (3) Hedging strategies, if successful, can reduce risk of loss by wholly
    or partially offsetting the negative  effect of unfavorable price  movements
    in the investments being hedged. However, hedging strategies can also reduce
    opportunity  for gain by  offsetting the positive  effect of favorable price
    movements in the hedged investments. For  example, if a Fund entered into  a
    short  hedge because the Sub-advisor  projected a decline in  the price of a
    security in the Fund's portfolio, and  the price of that security  increased
    instead,  the gain from that increase might be wholly or partially offset by
    a decline in the price of the hedging instrument. Moreover, if the price  of
    the  hedging instrument declined by  more than the increase  in the price of
    the security, the Fund could  suffer a loss. In  either such case, the  Fund
    would have been in a better position had it not hedged at all.
 
        (4)  As described below, a Fund might  be required to maintain assets as
    "cover," maintain segregated accounts or make margin payments when it  takes
    positions  in  instruments  involving obligations  to  third  parties (i.e.,
    instruments other than purchased  options). If a Fund  were unable to  close
    out  its positions in such instruments, it  might be required to continue to
    maintain such assets or  accounts or make such  payments until the  position
    expired or matured. The requirements might impair the Fund's ability to sell
    a portfolio security or make an investment at a time when it would otherwise
    be favorable to do so, or require that the Fund sell a portfolio security at
    a  disadvantageous time. The  Fund's ability to  close out a  position in an
    instrument prior to  expiration or maturity  depends on the  existence of  a
    liquid secondary market or, in the absence of such a market, the ability and
    willingness  of the other party to the transaction ("contra party") to enter
    into a  transaction  closing  out  the  position.  Therefore,  there  is  no
    assurance  that any position can  be closed out at a  time and price that is
    favorable to the Fund.
 
WRITING CALL OPTIONS
All Funds, other than the  Money Market Fund, may  write (sell) call options  on
securities,  currencies and  (except for the  Strategic Income  Fund, the Global
Government Income Fund and the U.S. Government Income Fund) stock indices.  Call
options  generally will  be written  on securities  and currencies  that, in the
opinion of the Sub-advisor, are  not expected to make  any major price moves  in
the  near  future but  that, over  the long  term, are  deemed to  be attractive
investments for the Fund.
 
A call option  gives the  holder (buyer)  the right  to purchase  a security  or
currency  at a specified price (the exercise  price) at any time until (American
style) or on (European style) a certain  date (the expiration date). As long  as
the  obligation of the writer of a call  option continues, he may be assigned an
exercise notice, requiring him  to deliver the  underlying security or  currency
against  payment  of the  exercise price.  This  obligation terminates  upon the
expiration of the call option, or such earlier time at which the writer  effects
a  closing  purchase  transaction  by purchasing  an  option  identical  to that
previously sold.
 
Portfolio securities or currencies on which call options may be written will  be
purchased  solely on the basis of investment considerations consistent with each
Fund's investment objective(s). When  writing a call option,  a Fund, in  return
for  the premium, gives up  the opportunity for profit  from a price increase in
the underlying security or  currency above the exercise  price, and retains  the
risk  of loss should the  price of the security  or currency decline. Unlike one
who owns  securities or  currencies not  subject to  an option,  a Fund  has  no
control  over  when it  may be  required  to sell  the underlying  securities or
currencies, since  most  options may  be  exercised at  any  time prior  to  the
option's  expiration. If a call option that a Fund has written expires, the Fund
will realize a  gain in the  amount of the  premium; however, such  gain may  be
offset  by a decline in the market  value of the underlying security or currency
during the option period. If the call option is exercised, the Fund will realize
a gain or loss from the sale of the underlying security or currency, which  will
be  increased or  offset by  the premium  received. A  Fund does  not consider a
security or currency covered by  a call option to be  "pledged" as that term  is
used  in the Fund's investment limitations that limit the pledging or mortgaging
of its assets.
 
Writing call options can serve as a limited short hedge because declines in  the
value  of the  hedged investment would  be offset  to the extent  of the premium
received  for  writing  the  option.  However,  if  the  security  or   currency
appreciates to a price higher than the exercise price of the call option, it can
be  expected that the option  will be exercised and a  Fund will be obligated to
sell the security or currency at less than its market value.
 
The premium  that  a Fund  receives  for writing  a  call option  is  deemed  to
constitute  the market value of an option.  The premium a Fund will receive from
writing a call option will reflect, among other things, the current market price
of the underlying  investment, the relationship  of the exercise  price to  such
market price, the historical price volatility of the
 
                  Statement of Additional Information Page 20
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
underlying  investment,  and the  length of  the  option period.  In determining
whether a  particular  call  option  should be  written,  the  Sub-advisor  will
consider the reasonableness of the anticipated premium and the likelihood that a
liquid secondary market will exist for those options.
 
Closing  transactions  will be  effected  in order  to  realize a  profit  on an
outstanding call  option, to  prevent an  underlying security  or currency  from
being  called, or  to permit  the sale of  the underlying  security or currency.
Furthermore, effecting a closing transaction will permit a Fund to write another
call option  on the  underlying security  or currency  with either  a  different
exercise price or expiration date or both.
 
A  Fund will pay transaction costs in connection with the writing of options and
in entering  into  closing purchase  contracts.  Transaction costs  relating  to
options  activity normally  are higher  than those  applicable to  purchases and
sales of portfolio securities.
 
The exercise price of the  options may be below, equal  to or above the  current
market  values of the  underlying securities, indices or  currencies at the time
the options are written. From  time to time, a  Fund may purchase an  underlying
security  or currency for delivery in accordance with the exercise of an option,
rather than delivering the  security or currency currently  held by it. In  such
cases, additional costs will be incurred.
 
A  Fund will realize a profit or loss from a closing purchase transaction if the
cost of the transaction is less or more, respectively, than the premium received
from writing the option. Because increases in the market price of a call  option
generally  will reflect increases in the market price of the underlying security
or currency, any loss resulting from the  repurchase of a call option is  likely
to  be offset in whole or in part  by appreciation of the underlying security or
currency owned by the Fund.
 
WRITING PUT OPTIONS
The Funds,  other  than  the  Money  Market  Fund,  may  write  put  options  on
securities,  currencies and  (except for the  Strategic Income  Fund, the Global
Government Income Fund and the U.S. Government Income Fund) stock indices. A put
option gives the  purchaser of  the option  the right  to sell,  and the  writer
(seller)  the  obligation to  buy, the  underlying security  or currency  at the
exercise price at  any time until  (American style) or  on (European style)  the
expiration date. The operation of put options in other respects, including their
related risks and rewards, is substantially identical to that of call options.
 
A  Fund generally would write put options in circumstances where the Sub-advisor
wishes to purchase the underlying security or  currency for the Fund at a  price
lower  than the current market price of the security or currency. In such event,
the Fund would  write a put  option at an  exercise price that,  reduced by  the
premium  received on the option, reflects the  lower price it is willing to pay.
Since the Fund  also would  receive interest  on debt  securities or  currencies
maintained  to cover the exercise  price of the option,  this technique could be
used to enhance current return during periods of market uncertainty. The risk in
such a transaction would be that the market price of the underlying security  or
currency would decline below the exercise price less the premiums received.
 
Writing  put options can serve as a  limited long hedge because increases in the
value of the  hedged investment would  be offset  to the extent  of the  premium
received   for  writing  the  option.  However,  if  the  security  or  currency
depreciates to a price lower than the  exercise price of the put option, it  can
be  expected that the put option will be  exercised and a Fund will be obligated
to purchase the security or currency at more than its market value.
 
PURCHASING PUT OPTIONS
Each Fund,  other  than the  Money  Market Fund,  may  purchase put  options  on
securities,  currencies and  (except for the  Strategic Income  Fund, the Global
Government Income Fund and  the U.S. Government Income  Fund) stock indices.  As
the  holder of a put option, a Fund  would have the right to sell the underlying
security or currency at the exercise price at any time until (American style) or
on (European style)  the expiration  date. A Fund  may enter  into closing  sale
transactions  with respect to  such option, exercise such  option or permit such
option to expire.
 
A Fund  may  purchase  a  put  option on  an  underlying  security  or  currency
("protective  put") owned by the Fund as a hedging technique in order to protect
against an anticipated decline  in the value of  the security or currency.  Such
hedge  protection is provided  only during the  life of the  put option when the
Fund, as the holder of the put  option, is able to sell the underlying  security
or  currency  at  the  put  exercise price  regardless  of  any  decline  in the
underlying security's market  price or  currency's exchange  value. The  premium
paid  for  the put  option and  any  transaction costs  would reduce  any profit
otherwise available for distribution when the security or currency eventually is
sold.
 
A Fund also may purchase put  options at a time when  the Fund does not own  the
underlying  security or  currency. By  purchasing put  options on  a security or
currency it does not own, a Fund seeks  to benefit from a decline in the  market
price
 
                  Statement of Additional Information Page 21
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
of  the underlying security or  currency. If the put option  is not sold when it
has remaining  value, and  if the  market price  of the  underlying security  or
currency  remains equal to or greater than the exercise price during the life of
the put option, the Fund will lose  its entire investment in the put option.  In
order for the purchase of a put option to be profitable, the market price of the
underlying  security or  currency must  decline sufficiently  below the exercise
price to cover the premium and transaction costs, unless the put option is  sold
in a closing sale transaction.
 
PURCHASING CALL OPTIONS
Each  Fund,  other than  the Money  Market  Fund, may  purchase call  options on
securities, currencies and  (except for  the Strategic Income  Fund, the  Global
Government  Income Fund and  the U.S. Government Income  Fund) stock indices. As
the holder  of a  call option,  a  Fund would  have the  right to  purchase  the
underlying  security  or  currency  at  the exercise  price  at  any  time until
(American style) or on  (European style) the expiration  date. A Fund may  enter
into closing sale transactions with respect to such option, exercise such option
or permit such option to expire.
 
Call  options  may be  purchased  by a  Fund for  the  purpose of  acquiring the
underlying security or currency for its portfolio. Utilized in this fashion, the
purchase of call options would enable a Fund to acquire the security or currency
at the exercise price of the call option plus the premium paid. At times the net
cost of acquiring the security or currency  in this manner may be less than  the
cost  of acquiring the security or currency directly. This technique also may be
useful to the Funds in purchasing a large block of securities that would be more
difficult to acquire by direct market purchases. So long as it holds such a call
option, rather  than the  underlying  security or  currency  itself, a  Fund  is
partially  protected  from any  unexpected decline  in the  market price  of the
underlying security or currency and, in such event, could allow the call  option
to  expire, incurring  a loss  only to the  extent of  the premium  paid for the
option.
 
Each Fund also may purchase call options on underlying securities or  currencies
it  owns in order to protect unrealized gains on call options previously written
by  it.  A  call  option  could   be  purchased  for  this  purpose  where   tax
considerations  make  it inadvisable  to realize  such  gains through  a closing
purchase transaction.  Call options  also may  be purchased  at times  to  avoid
realizing  losses that would result  in a reduction of  a Fund's current return.
For example, where a Fund has written a call option on an underlying security or
currency having a current market value below the price at which it purchased the
security or  currency, an  increase in  the  market price  could result  in  the
exercise of the call option written by the Fund and the realization of a loss on
the underlying security or currency. Accordingly, the Fund could purchase a call
option  on the same underlying security or currency, which could be exercised to
fulfill the  Fund's  delivery obligations  under  its  written call  (if  it  is
exercised).  This strategy could  allow the Fund to  avoid selling the portfolio
security or currency at a time when it has an unrealized loss; however, the Fund
would have to pay a premium to purchase the call option plus transaction costs.
 
Aggregate premiums paid  for put  and call  options will  not exceed  5% of  the
Fund's total assets at the time of purchase.
 
Each  Fund may  attempt to  accomplish objectives  similar to  those involved in
using Forward Contracts by purchasing put  or call options on currencies. A  put
option  gives a Fund as  purchaser the right (but not  the obligation) to sell a
specified amount of currency at the  exercise price at any time until  (American
style)  or on (European style) the expiration  date of the option. A call option
gives a Fund  as purchaser  the right  (but not  the obligation)  to purchase  a
specified  amount of currency at the exercise  price at any time until (American
style) or on (European style)  the expiration date of  the option. A Fund  might
purchase a currency put option, for example, to protect itself against a decline
in  the dollar  value of  a currency  in which  it holds  or anticipates holding
securities. If the currency's value should decline against the dollar, the  loss
in  currency value should be offset, in whole  or in part, by an increase in the
value of the put. If the value  of the currency instead should rise against  the
dollar, any gain to the Fund would be reduced by the premium it had paid for the
put  option.  A  currency  call  option  might  be  purchased,  for  example, in
anticipation of, or to protect against, a  rise in the value against the  dollar
of a currency in which the Fund anticipates purchasing securities.
 
Options  may be either listed on an exchange or traded over-the-counter ("OTC").
Listed options are third-party contracts  (i.e., performance of the  obligations
of  the  purchaser  and  seller  is  guaranteed  by  the  exchange  or  clearing
corporation), and  have standardized  strike prices  and expiration  dates.  OTC
options  are two-party  contracts with  negotiated strike  prices and expiration
dates. A Fund  will not purchase  an OTC  option unless it  believes that  daily
valuations  for such  options are  readily obtainable.  OTC options  differ from
exchange-traded options in that OTC options are transacted with dealers directly
and  not  through  a   clearing  corporation  (which  guarantees   performance).
Consequently,  there  is  a risk  of  non-performance  by the  dealer.  Since no
exchange is involved, OTC options are valued  on the basis of an average of  the
last  bid prices, obtained from dealers, unless a quotation from only one dealer
is available, in which case only that  dealer's price will be used. In the  case
of  OTC options, there can  be no assurance that  a liquid secondary market will
exist for any particular option at any specific time.
 
                  Statement of Additional Information Page 22
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
 
The staff of the SEC considers purchased OTC options to be illiquid  securities.
A  Fund may also sell OTC options and, in connection therewith, segregate assets
or cover its obligations with  respect to OTC options  written by the Fund.  The
assets  used  as cover  for OTC  options written  by a  Fund will  be considered
illiquid unless the OTC options are sold to qualified dealers who agree that the
Fund may repurchase any OTC option it writes at a maximum price to be calculated
by a formula  set forth in  the option agreement.  The cover for  an OTC  option
written  subject  to this  procedure would  be considered  illiquid only  to the
extent that the maximum repurchase price under the formula exceeds the intrinsic
value of the option.
 
A Fund's ability to establish and close out positions in exchange-listed options
depends on the existence of  a liquid market. Each  Fund intends to purchase  or
write  only those exchange-traded options for which there appears to be a liquid
secondary market. However,  there can be  no assurance that  such a market  will
exist  at any particular time. Closing transactions  can be made for OTC options
only by negotiating directly with the contra  party, or by a transaction in  the
secondary  market if any such market exists.  Although each Fund will enter into
OTC options only with contra parties that are expected to be capable of entering
into closing transactions  with the Fund,  there is no  assurance that the  Fund
will  in fact be able to  close out an OTC option  position at a favorable price
prior to expiration. In the  event of insolvency of  the contra party, the  Fund
might  be unable to  close out an OTC  option position at any  time prior to its
expiration.
 
INDEX OPTIONS
Puts and calls on indices are similar to puts and calls on securities or futures
contracts except that all settlements  are in cash and  gain or loss depends  on
changes  in the index in question (and thus on price movements in the securities
market or a particular market sector  generally) rather than on price  movements
in  individual securities or futures contracts. When  a Fund writes a call on an
index, it receives a premium and agrees that, prior to the expiration date,  the
purchaser  of the call, upon exercise of the call, will receive from the Fund an
amount of cash if the closing level of the index upon which the call is based is
greater than the exercise price of the call. The amount of cash is equal to  the
difference  between the closing price of the index and the exercise price of the
call times a specified multiple  (the "multiplier"), which determines the  total
dollar  value for each point of  such difference. When a Fund  buys a call on an
index, it  pays a  premium  and has  the same  rights  as to  such call  as  are
indicated  above. When a Fund buys a put on  an index, it pays a premium and has
the right, prior to the expiration date, to require the seller of the put,  upon
the  Fund's exercise of the put, to deliver to the Fund an amount of cash if the
closing level of the index upon which the put is based is less than the exercise
price of the  put, which  amount of  cash is  determined by  the multiplier,  as
described  above for calls. When a Fund writes  a put on an index, it receives a
premium and  the purchaser  has the  right,  prior to  the expiration  date,  to
require  the Fund  to deliver to  it an amount  of cash equal  to the difference
between the  closing  level  of the  index  and  the exercise  price  times  the
multiplier, if the closing level is less than the exercise price.
 
The  risks  of  investment in  index  options  may be  greater  than  options on
securities. Because index options are settled in cash, when a Fund writes a call
on  an  index  it  cannot  provide  in  advance  for  its  potential  settlement
obligations  by  acquiring and  holding the  underlying  securities. A  Fund can
offset some of the  risk of writing  a call index option  position by holding  a
diversified  portfolio of  securities similar to  those on  which the underlying
index is based. However, a Fund cannot, as a practical matter, acquire and  hold
a portfolio containing exactly the same securities as underlie the index and, as
a  result, bears a risk that the value of the securities held will vary from the
value of the index.
 
Even if a Fund could assemble a securities portfolio that exactly reproduced the
composition of the underlying index, it still would not be fully covered from  a
risk  standpoint because of the "timing risk" inherent in writing index options.
When an  index option  is  exercised, the  amount of  cash  that the  holder  is
entitled  to receive is determined by  the difference between the exercise price
and the closing index level  on the date when the  option is exercised. As  with
other  kinds of options, the Fund  as the call writer will  not know that it has
been assigned until the next business day at the earliest. The time lag  between
exercise and notice of assignment poses no risk for the writer of a covered call
on  a  specific underlying  security, such  as common  stock, because  there the
writer's obligation is to deliver the underlying security, not to pay its  value
as  of  a fixed  time  in the  past.  So long  as  the writer  already  owns the
underlying security,  it  can  satisfy  its  settlement  obligations  by  simply
delivering  it, and the risk that its value may have declined since the exercise
date is borne by the  exercising holder. In contrast, even  if the writer of  an
index call holds securities that exactly match the composition of the underlying
index,  it will not be able to  satisfy its assignment obligations by delivering
those securities against  payment of  the exercise  price. Instead,  it will  be
required  to pay  cash in  an amount  based on  the closing  index value  on the
exercise date; and by the  time it learns that it  has been assigned, the  index
may  have declined, with a corresponding decline  in the value of its securities
portfolio. This "timing risk" is an inherent limitation on the ability of  index
call writers to cover their risk exposure by holding securities positions.

If  a Fund purchases an  index option and exercises  it before the closing index
value for  that day  is  available, it  runs  the risk  that  the level  of  the
underlying  index may subsequently change. If such a change causes the exercised
option to fall out-of-the-money, the Fund will be required to pay the difference
between the closing index value and the exercise price of the option (times  the
applicable multiplier) to the assigned writer.
 
INTEREST RATE, CURRENCY AND STOCK INDEX FUTURES CONTRACTS
The  Funds, except for  the Money Market  Fund, may enter  into interest rate or
currency futures contracts, and the Funds, except for the Strategic Income Fund,
the Global Government Income Fund, the U.S. Government Income Fund and the Money
Market Fund, may enter into stock index futures contracts ("Futures" or "Futures
Contracts"), as a hedge against changes in prevailing levels of interest  rates,
currency  exchange  rates  or stock  price  levels  in order  to  establish more
definitely the effective return on securities or currencies held or intended  to
be  acquired by the Funds. The Funds' hedging may include sales of Futures as an
offset against the effect of expected  increases in interest rates, or  declines
in currency exchange rates or stock prices and purchases of futures as an offset
against  the  effect of  expected  declines in  interest  rates or  increases in
currency exchange rates or stock prices.
 
The Funds only  will enter  into Futures Contracts  that are  traded on  futures
exchanges  and are  standardized as  to maturity  date and  underlying financial
instrument. Futures  exchanges and  trading  thereon in  the United  States  are
regulated  under the  Commodity Exchange  Act by  the Commodity  Futures Trading
Commission ("CFTC"). Futures are exchanged in London at the London International
Financial Futures Exchange.
 
Although techniques other than sales and purchases of Futures Contracts could be
used to reduce the Funds' exposure  to interest rate and currency exchange  rate
fluctuations, a Fund may be able to hedge its exposure more effectively and at a
lower cost through using Futures Contracts.
 
A  Futures Contract provides  for the future  sale by one  party and purchase by
another party of a specified amount of a specific financial instrument (security
or currency) for a specified price at a designated date, time and place. A index
Futures Contract  provides for  the delivery,  at a  designated date,  time  and
place,  of  an amount  of  cash equal  to a  specified  dollar amount  times the
difference between the index value at the  close of trading on the contract  and
the  price  at which  the  Futures Contract  is  originally struck;  no physical
delivery of the  securities comprising  the index  is made.  Brokerage fees  are
incurred  when a Futures Contract is bought or sold, and margin deposits must be
maintained at all times during which the Futures Contract is outstanding.
 
Although Futures Contracts typically require future delivery of and payment  for
financial  instruments or currencies,  Futures Contracts usually  are closed out
before the delivery date. Closing out an open Futures Contract sale or  purchase
is  effected by entering  into an offsetting Futures  Contract purchase or sale,
respectively,  for  the  same  aggregate  amount  of  the  identical   financial
instrument  or currency and  the same delivery date.  If the offsetting purchase
price is less than the original sale price,  the Fund realizes a gain; if it  is
more, the Fund realizes a loss. Conversely, if the offsetting sale price is more
than  the original purchase price, the Fund realizes  a gain; if it is less, the
Fund realizes  a loss.  The transaction  costs also  must be  included in  these
calculations. There can be no assurance, however, that the Funds will be able to
enter  into  an  offsetting transaction  with  respect to  a  particular Futures
Contract at a particular time. If a Fund is not able to enter into an offsetting
transaction, the  Fund will  continue  to be  required  to maintain  the  margin
deposits on the Futures Contract.
 
As  an example of an offsetting transaction, the contractual obligations arising
from the sale of one Futures Contract of September Deutschemarks on an  exchange
may  be fulfilled  at any  time before  delivery under  the Futures  Contract is
required (i.e., on a specified date  in September, the "delivery month") by  the
purchase  of another  Futures Contract  of September  Deutschemarks on  the same
exchange. In  such instance,  the  difference between  the  price at  which  the
Futures  Contract was sold and the price paid for the offsetting purchase, after
allowance for transaction costs, represents the profit or loss to the Fund.
 
The Funds'  Futures transactions  generally  will be  entered into  for  hedging
purposes,  except  as discussed  below  under "Synthetic  Securities";  that is,
Futures Contracts will  be sold to  protect against  a decline in  the price  of
securities  or  currencies  that  a  Fund owns,  or  Futures  Contracts  will be
purchased to protect the Funds against an increase in the price of securities or
currencies it has committed to purchase or expects to purchase.
 
"Margin" with respect to Futures Contracts is  the amount of funds that must  be
deposited  by a Fund  in order to  initiate Futures trading  and to maintain the
Fund's open  positions in  Futures Contracts.  A margin  deposit made  when  the
Futures  Contract is entered  into ("initial margin") is  intended to ensure the
Fund's performance  under  the  Futures  Contract. The  margin  required  for  a
particular Futures Contract is set by the exchange on which the Futures Contract
is  traded and may be  significantly modified from time  to time by the exchange
during the term of the Futures Contract.
 
                  Statement of Additional Information Page 24

                      GT GLOBAL VARIABLE INVESTMENT FUNDS
 
Subsequent  payments,  called  "variation  margin,"  to  and  from  the  futures
commission  merchant through  which the Fund  entered into  the Futures Contract
will be made on a daily basis as the price of the underlying security,  currency
or index fluctuates making the Futures Contract more or less valuable, a process
known as marking-to-market.
 
    RISKS  OF  USING  FUTURES CONTRACTS.  The  prices of  Futures  Contracts are
volatile and  are influenced  by,  among other  things, actual  and  anticipated
changes in interest and currency rates, which in turn are affected by fiscal and
monetary policies and national and international political and economic events.
 
There  is a risk of  imperfect correlation between changes  in prices of Futures
Contracts and prices of  the Fund's securities or  currencies being hedged.  The
degree  of  imperfection  of  correlation depends  upon  circumstances  such as:
variations in  speculative  market demand  for  Futures and  for  securities  or
currencies,  including technical influences in  Futures trading; and differences
between the financial  instruments being hedged  and the instruments  underlying
the  standard Futures  Contracts available for  trading. A  decision of whether,
when and how  to hedge involves  skill and judgment,  and even a  well-conceived
hedge  may be unsuccessful to some  degree because of unexpected market behavior
or interest or currency rate trends.
 
Because of  the  low  margin  deposits required,  Futures  trading  involves  an
extremely  high  degree  of leverage.  As  a  result, a  relatively  small price
movement in a Futures Contract may result in immediate and substantial loss,  as
well  as gain, to the investor. For example,  if at the time of purchase, 10% of
the value  of the  Futures Contract  is deposited  as margin,  a subsequent  10%
decrease  in the value of  the Futures Contract would result  in a total loss of
the margin  deposit, before  any deduction  for the  transaction costs,  if  the
account  were then closed  out. A 15% decrease  would result in  a loss equal to
150% of the original  margin deposit, if the  Futures Contract were closed  out.
Thus, a purchase or sale of a Futures Contract may result in losses in excess of
the amount invested in the Futures Contract.
 
Most U.S. futures exchanges limit the amount of fluctuation permitted in Futures
Contract  and option on Futures Contract prices during a single trading day. The
daily limit establishes the maximum amount that the price of a Futures  Contract
or option may vary either up or down from the previous day's settlement price at
the  end  of a  trading session.  Once the  daily  limit has  been reached  in a
particular type of Futures Contract or option, no trades may be made on that day
at a price beyond that limit. The daily limit governs only price movement during
a particular trading day and therefore does not limit potential losses,  because
the limit may prevent the liquidation of unfavorable positions. Futures Contract
and  option  prices  occasionally have  moved  to  the daily  limit  for several
consecutive trading days with  little or no  trading, thereby preventing  prompt
liquidation of positions and subjecting some traders to substantial losses.
 
If  a Fund were unable to liquidate a  Futures or option on Futures position due
to the absence of a liquid secondary  market or the imposition of price  limits,
it  could incur  substantial losses.  The Fund would  continue to  be subject to
market risk with respect  to the position.  In addition, except  in the case  of
purchased  options,  the  Fund  would  continue to  be  required  to  make daily
variation margin payments and might be  required to maintain the position  being
hedged by the Future or option or to maintain cash or securities in a segregated
account.
 
Certain  characteristics  of the  Futures market  might  increase the  risk that
movements in the  prices of Futures  Contracts or options  on Futures might  not
correlate  perfectly  with  movements in  the  prices of  the  investments being
hedged. For example,  all participants  in the  Futures and  options on  Futures
markets  are subject to daily  variation margin calls and  might be compelled to
liquidate Futures  or  options on  Futures  positions whose  prices  are  moving
unfavorably  to avoid being  subject to further  calls. These liquidations could
increase price  volatility  of the  instruments  and distort  the  normal  price
relationship  between the Futures  or options and  the investments being hedged.
Also, because of initial margin deposit  requirements in the Futures market  are
less  onerous than margin requirements in the securities markets, there might be
increased  participation   by  speculators   in   the  Futures   markets.   This
participation  also  might  cause  temporary  price  distortions.  In  addition,
activities of large traders in both the Futures and securities markets involving
arbitrage, "program trading"  and other  investment strategies  might result  in
temporary price distortions.
 
OPTIONS ON FUTURES CONTRACTS
Options  on Futures Contracts are similar to options on securities or currencies
except that options on Futures Contracts give the purchaser the right, in return
for the  premium paid,  to  assume a  position in  a  Futures Contract  (a  long
position if the option is a call and short position if the option is a put) at a
specified  exercise price  at any  time during  the period  of the  option. Upon
exercise of the option, the  delivery of the Futures  position by the writer  of
the  option to the holder  of the option will be  accompanied by delivery of the
accumulated balance in the writer's Futures margin account, which represents the
amount by which the market price  of the Futures Contract, at exercise,  exceeds
(in  the case of  a call) or  is less than (in  the case of  a put) the exercise
price of the option on  the Futures Contract. If an  option is exercised on  the
last trading day prior to the expiration date of the option, the settlement will
be made entirely in cash equal to the difference
 
                  Statement of Additional Information Page 25
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
between  the  exercise  price  of  the  option  and  the  closing  level  of the
securities, currencies or index upon which the Futures Contract is based on  the
expiration  date. Purchasers of options who fail to exercise their options prior
to the exercise date suffer a loss of the premium paid.
 
The purchase of  call options  on Futures  can serve as  a long  hedge, and  the
purchase  of put  options on Futures  can serve  as a short  hedge. Writing call
options on Futures can serve as a  limited short hedge, and writing put  options
on  Futures can serve as a limited long  hedge, using a strategy similar to that
used for writing options on securities, foreign currencies or indices.
 
If a Fund writes an option on a Futures Contract, it will be required to deposit
initial  and  variation  margin  pursuant  to  requirements  similar  to   those
applicable to Futures Contracts. Premiums received from the writing of an option
on a Futures Contract are included in the initial margin deposit.
 
A  Fund may seek to  close out an option position  by selling an option covering
the same Futures  Contract and  having the  same exercise  price and  expiration
date.  The  ability to  establish and  close  out positions  on such  options is
subject to the maintenance of a liquid secondary market.
 
LIMITATION ON  USE  OF  FUTURES,  OPTIONS ON  FUTURES  AND  CERTAIN  OPTIONS  ON
CURRENCIES
To  the extent  that a  Fund enters into  Futures Contracts,  options on Futures
Contracts,  and  options  on  foreign  currencies  traded  on  a  CFTC-regulated
exchange,  in each case other than for bona fide hedging purposes (as defined by
the CFTC), the aggregate initial margin and premiums required to establish those
positions (excluding the amount  by which options  are "in-the-money") will  not
exceed  5% of  the liquidation  value of a  Fund's portfolio,  after taking into
account unrealized profits and unrealized losses  on any contracts the Fund  has
entered  into. In general, a call option on a Futures Contract is "in-the-money"
if the  value of  the  underlying Futures  Contract  exceeds the  strike,  i.e.,
exercise,   price  of  the  call;  a  put   option  on  a  Futures  Contract  is
"in-the-money" if the value  of the underlying Futures  Contract is exceeded  by
the  strike price of the  put. This guideline may  be modified by each Company's
Board of Trustees without a shareholder vote. This limitation does not limit the
percentage of a Fund's assets at risk to 5%.
 
FORWARD CONTRACTS
A Forward Contract is an obligation, usually arranged with a commercial bank  or
other  currency dealer, to purchase or  sell a currency against another currency
at a future  date and price  as agreed upon  by the parties.  A Fund may  either
accept or make delivery of the currency at the maturity of the Forward Contract.
A  Fund may also,  if its contra party  agrees, prior to  maturity, enter into a
closing transaction involving the purchase or sale of an offsetting contract.
 
A Fund  engages in  forward  currency transactions  in  anticipation of,  or  to
protect  itself against,  fluctuations in  exchange rates.  A Fund  might sell a
particular  foreign  currency  forward,  for   example,  when  it  holds   bonds
denominated  in a  foreign currency but  anticipates, and seeks  to be protected
against, a decline in  the currency against the  U.S. dollar. Similarly, a  Fund
might  sell the  U.S. dollar  forward when  it holds  bonds denominated  in U.S.
dollars but anticipates,  and seeks to  be protected against,  a decline in  the
U.S.  dollar  relative to  other currencies.  Further, a  Fund might  purchase a
currency forward  to "lock  in"  the price  of  securities denominated  in  that
currency that it anticipates purchasing.
 
Forward  Contracts are traded in the interbank market conducted directly between
currency traders (usually large commercial banks) and their customers. A Forward
Contract generally has no deposit requirement, and no commissions are charged at
any stage for trades. A Fund will  enter into such Forward Contracts with  major
U.S.  or foreign  banks and  securities or  currency dealers  in accordance with
guidelines approved by that Company's Board of Trustees.
 
A Fund  may  enter  into  Forward Contracts  either  with  respect  to  specific
transactions or with respect to the overall investments of the Fund. The precise
matching  of the Forward  Contract amounts and the  value of specific securities
generally will not 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 the Forward Contract  is entered into and
the date it matures.  Accordingly, it may  be necessary for  a Fund to  purchase
additional  foreign  currency on  the  spot (i.e.,  cash)  market (and  bear the
expense of such purchase) if the market  value of the security is less than  the
amount of foreign currency the Fund is obligated to deliver and if a decision is
made to sell the security and make delivery of the foreign currency. Conversely,
it  may be necessary to sell on the spot market some of the foreign currency the
Fund is  obligated to  deliver.  The projection  of short-term  currency  market
movements  is extremely difficult, and the  successful execution of a short-term
hedging strategy is highly  uncertain. Forward Contracts  involve the risk  that
anticipated  currency movements will not be predicted accurately, causing a Fund
to sustain losses on such contracts and transaction costs.
 
At or before  the maturity  of a  Forward Contract requiring  a Fund  to sell  a
currency,  the Fund may either sell a security and use the sale proceeds to make
delivery of  the currency  or retain  the security  and offset  its  contractual
obligation to deliver
 
                  Statement of Additional Information Page 26
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
the  currency by purchasing  a second contract  pursuant to which  the Fund will
obtain, on the same maturity  date, the same amount of  the currency that it  is
obligated  to  deliver.  Similarly, a  Fund  may  close out  a  Forward Contract
requiring it  to  purchase  a  specified currency  by  entering  into  a  second
contract,  if its contra party  agrees, entitling it to  sell the same amount of
the same currency on  the maturity date  of the first  contract. The Fund  would
realize  a gain or loss as a result  of entering into such an offsetting Forward
Contract under either  circumstance to  the extent  the exchange  rate or  rates
between  the currencies involved moved between  the execution dates of the first
Forward Contract and the offsetting Forward Contract.
 
The cost to a Fund of engaging in Forward Contracts varies with factors such  as
the  currencies  involved, the  length  of the  contract  period and  the market
conditions then prevailing. Because Forward  Contracts usually are entered  into
on  a principal basis, no  fees or commissions are  involved. The use of Forward
Contracts does  not  eliminate fluctuations  in  the prices  of  the  underlying
securities  a Fund owns or  intends to acquire, but it  does establish a rate of
exchange in advance. In addition, while Forward Contracts limit the risk of loss
due to a  decline in the  value of the  hedged currencies, they  also limit  any
potential gain that might result should the value of the currencies increase.
 
FOREIGN CURRENCY STRATEGIES -- SPECIAL CONSIDERATIONS
A  Fund may  use options on  foreign currencies, Futures  on foreign currencies,
options on Futures on foreign currencies and Forward Contracts, to hedge against
movements in the values of the foreign currencies in which the Fund's securities
are denominated. Such currency hedges can  protect against price movements in  a
security  that the  Fund owns  or intends  to acquire  that are  attributable to
changes in the value of the currency in which it is denominated. Such hedges  do
not,  however,  protect  against  price movements  in  the  securities  that are
attributable to other causes.
 
A Fund might seek to hedge against changes in the value of a particular currency
when no Futures Contract, Forward Contract or option involving that currency  is
available  or  one  of  such  contracts is  more  expensive  than  certain other
contracts. In such  cases, the Fund  may hedge against  price movements in  that
currency  by  entering  into  a  contract  on  another  currency  or  basket  of
currencies, the values of  which the Sub-advisor believes  will have a  positive
correlation  to the value of the currency  being hedged. The risk that movements
in the price of the contract will not correlate perfectly with movements in  the
price of the currency being hedged is magnified when this strategy is used.
 
The  value of Futures Contracts, options on Futures Contracts, Forward Contracts
and options  on  foreign currencies  depends  on  the value  of  the  underlying
currency  relative  to the  U.S. dollar.  Because foreign  currency transactions
occurring in the  interbank market  might involve  substantially larger  amounts
than  those  involved in  the  use of  Futures  Contracts, Forward  Contracts or
options, a  Fund  could  be disadvantaged  by  dealing  in the  odd  lot  market
(generally  consisting  of  transactions  of  less  than  $1  million)  for  the
underlying foreign currencies at prices that  are less favorable than for  round
lots.
 
There is no systematic reporting of last sale information for foreign currencies
or  any  regulatory requirements  that quotations  available through  dealers or
other market sources be firm or revised on a timely basis. Quotation information
generally is representative of very  large transactions in the interbank  market
and  thus  might not  reflect  odd-lot transactions  where  rates might  be less
favorable.  The   interbank  market   in  foreign   currencies  is   a   global,
round-the-clock  market. To the  extent the U.S. options  or Futures markets are
closed while the markets for the underlying currencies remain open,  significant
price  and rate movements might take place in the underlying markets that cannot
be reflected in  the markets  for the Futures  contracts or  options until  they
reopen.
 
Settlement of Futures Contracts, Forward Contracts and options involving foreign
currencies  might  be required  to  take place  within  the country  issuing the
underlying currency. Thus, a Fund might  be required to accept or make  delivery
of  the  underlying foreign  currency  in accordance  with  any U.S.  or foreign
regulations regarding the  maintenance of foreign  banking arrangements by  U.S.
residents  and might be required  to pay any fees,  taxes and charges associated
with such delivery assessed in the issuing country.
 
COVER
Transactions using Forward Contracts, Futures Contracts and options (other  than
options  purchased by a Fund) expose the Fund to an obligation to another party.
A Fund will not enter  into any such transactions unless  it owns either (1)  an
offsetting  ("covered") position  in securities,  currencies, or  other options,
Forward Contracts or Futures Contracts, or (2) cash, receivables and  short-term
debt  securities with  a value  sufficient at all  times to  cover its potential
obligations not covered as provided in (1) above. Each Fund will comply with SEC
guidelines regarding  cover for  these  instruments and,  if the  guidelines  so
require, set aside cash or liquid securities.
 
Assets  used as cover or  held in a segregated account  cannot be sold while the
position in the corresponding  Forward Contract, Futures  Contract or option  is
open, unless they are replaced with other appropriate assets. If a large portion
of a
 
                  Statement of Additional Information Page 27
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
Fund's  assets  is  used for  cover  or  otherwise set  aside,  it  could affect
portfolio management or the Fund's ability to meet redemption requests or  other
current obligations.
 
SYNTHETIC SECURITY POSITIONS
The  Global  Government Income  Fund  and the  Strategic  Income Fund,  each may
utilize, up to  5% of its  total assets,  combinations of futures  on bonds  and
forward   currency   contracts  to   create   investment  positions   that  have
substantially the same  characteristics as bonds  of the same  type as those  on
which  the futures contracts are written.  Investment positions of this type are
generally referred to as "synthetic securities."
 
For example, in order to establish a synthetic security position for a Fund that
is comparable  to  owning a  Japanese  government bond,  the  Sub-advisor  might
purchase futures contracts on Japanese government bonds in the desired principal
amount  and purchase  forward currency contracts  for Japanese Yen  in an amount
equal to the then  current purchase price  for such bonds  in the Japanese  cash
market, with each contract having approximately the same delivery date.
 
The  Sub-advisor  might  roll over  the  futures and  forward  currency contract
positions before  taking delivery  in order  to continue  the Fund's  investment
position,  or the Sub-advisor might close  out those positions, thus effectively
selling the synthetic security.  Further, the amount of  each contract might  be
adjusted  in response  to market  conditions and  the forward  currency contract
might be changed  in amount  or eliminated in  order to  hedge against  currency
fluctuations.
 
Further,  while these futures and currency contracts remain open, the Funds will
comply with  applicable  SEC  guidelines  to set  aside  cash,  U.S.  government
securities  or other liquid  high grade debt securities  in a segregated account
with its custodian in  an amount sufficient to  cover its potential  obligations
under such contracts.
 
The  Sub-advisor would  create synthetic security  positions for a  Fund when it
believes that it can obtain a better yield or achieve cost savings in comparison
to purchasing actual bonds or when comparable bonds are not readily available in
the market. Synthetic security positions are subject to the risk that changes in
the value of purchased futures contracts may differ from changes in the value of
the bonds that might otherwise have been purchased in the cash market.
 
Also, while  the  Sub-advisor  believes  that the  cost  of  creating  synthetic
security positions generally will be materially lower than the cost of acquiring
comparable  bonds in  the cash  market, a Fund  will incur  transaction costs in
connection with each purchase of a futures or forward currency contract. The use
of futures contracts and forward currency contracts to create synthetic security
positions also is subject  to substantially the same  risks as those that  exist
when these instruments are used in connection with hedging strategies.
 
INTEREST RATE AND CURRENCY SWAPS
The  Strategic  Income Fund  may enter  into interest  rate, currency  and index
swaps, and  purchase  or  sell  related  caps,  floors  and  collars  and  other
derivative  instruments. The Strategic  Income Fund expects  to enter into these
transactions primarily to preserve a return or spread on a particular investment
or portion of  its portfolio,  to protect  against currency  fluctuations, as  a
technique  for managing the portfolio's duration (i.e., the price sensitivity to
changes in interest rates) or  to protect against any  increase in the price  of
securities  it anticipates purchasing at a later date. The Strategic Income Fund
intends to use  these transactions as  hedges, and will  not sell interest  rate
caps  or floors if it does not  own securities or other instruments providing an
income stream roughly equivalent to what it may become obligated to pay.
 
Interest rate  swaps involve  the exchange  by the  Strategic Income  Fund  with
another  party of their  respective commitments to pay  or receive interest (for
example, an exchange  of floating rate  payments for fixed  rate payments)  with
respect  to a notional amount  of principal. A currency  swap is an agreement to
exchange cash flows on a notional amount  based on changes in the values of  the
reference indices.
 
The  purchase of a cap entitles the  purchaser to receive payments on a notional
principal amount from the party selling the  cap to the extent that a  specified
index  exceeds a predetermined  interest rate. The purchase  of an interest rate
floor entitles  the purchaser  to receive  payments of  interest on  a  notional
principal  amount from the party  selling the interest rate  floor to the extent
that a specified index  falls below a predetermined  interest rate or amount.  A
collar  is a combination  of a cap and  a floor that  preserves a certain return
with a predetermined range of interest rates or values.
 
The Strategic Income Fund usually will enter into swaps on a net basis, that is,
the two payment streams are netted out in a cash settlement on the payment  date
or  dates specified in the  instrument, with the Fund's  receiving or paying, as
the case may be, only the net amount of the two payments. The net amount of  the
excess, if any, of the Strategic Income Fund's obligations over its entitlements
with  respect to each swap, will  be accrued on a daily  basis, and an amount of
cash or liquid securities having an aggregate net asset value at least equal  to
the  accrued  excess, will  be  maintained in  an  account by  a  custodian that
satisfies the requirement of the 1940  Act. The Strategic Income Fund will  also
establish and maintain such

segregated  accounts with respect to its  total obligations under any swaps that
are not entered into on a net basis and with respect to any caps or floors  that
are  written by the Fund. The Sub-advisor  and the Strategic Income Fund believe
that swaps, caps and floors do  not constitute senior securities under the  1940
Act  and,  accordingly, will  not  treat them  as  being subject  to  the Fund's
borrowing restrictions.
 
The Strategic Income Fund will  not enter into any  swap, cap, floor, collar  or
other   derivative  transaction  unless,  at  the  time  of  entering  into  the
transaction, the unsecured  long-term debt rating  of the counterparty  combined
with  any credit enhancements is rated at  least A by Moody's Investors Service,
Inc. ("Moody's") or Standard & Poor's, a division of The McGraw-Hill  Companies,
("S&P"),  or has an  equivalent rating from  a nationally recognized statistical
rating organization or is determined to  be of equivalent credit quality by  the
Sub-advisor.  If a  counterparty defaults,  the Strategic  Income Fund  may have
contractual remedies pursuant to the agreements related to the transactions. 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. Caps, floors and  collars are more recent innovations
for which standardized documentation has not yet been fully developed, and,  for
that reason, they are less liquid than swaps.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
Equity  securities,  particularly common  stocks,  generally represent  the most
junior position  in an  issuer's capital  structure and  entitle holders  to  an
interest  in the assets  of an issuer,  if any, remaining  after all more senior
claims are satisfied.
 
RISK FACTORS OF SPECIFIC FUNDS
 
    THE NEW  PACIFIC  FUND.  Certain  countries, such  as  India,  face  serious
exchange constraints. Jurisdictional disputes also exist between South Korea and
North  Korea. In addition, Hong Kong  reverted to Chinese administration on July
1, 1997. The long-term  effects of this  reversion are not  known at this  time.
However,  the Fund's investments in Hong Kong may  now be subject to the same or
similar risks as any  investment in China. Investments  in Hong Kong may  become
subject  to expropriation, nationalization,  or confiscation, in  which case the
Fund could lose its entire investment  in Hong Kong. In addition, the  reversion
of Hong Kong also presents a risk that the Hong Kong dollar will be devalued and
a  risk of possible loss  of investor confidence in  Hong Kong's currency, stock
market, and economy.
 
    THE INFRASTRUCTURE FUND. Prices of securities of smaller companies in  which
the Fund invests may fluctuate to a greater degree than the prices of securities
of other issuers.
 
The  nature  of political,  environmental and  other government  regulation over
infrastructure companies continues to  evolve in both the  United States and  in
foreign  countries,  and  changes  in  governmental  policy  and  the  need  for
regulatory approvals may  have a material  effect on the  products and  services
offered  by companies in the infrastructure industries. Electric, gas, water and
most telecommunications companies in the U.S., for example, are subject to  both
federal  and state regulation affecting permitted  rates of return and the kinds
of services that may be offered.
 
Many infrastructure  companies have  been  subject to  risks attendant  to  high
interest  on  borrowed funds  and changes  in  the regulatory  climate. Further,
competition is intense for  many of the infrastructure  companies. As a  result,
many  of  these companies  may  be adversely  affected  in the  future  and such
companies may be subject to increased share price volatility. In addition,  many
companies  have diversified  into oil  and gas  exploration and  development and
therefore returns may be more  sensitive to energy prices. Other  infrastructure
companies,  such as water supply companies,  are in highly fragmented industries
due  to  local  ownership.  Generally,  these  companies  are  mature  and   are
experiencing little or no growth.
 
    THE NATURAL RESOURCES FUND. The nature of political, environmental and other
government  regulation over natural  resources companies continues  to evolve in
both the United  States and in  foreign countries, and  changes in  governmental
policy  and the need for regulatory approvals  may have a material effect on the
products and services offered by companies in the natural resources  industries.
For  example, the exploration, development and distribution of coal, oil and gas
in the United States  are subject to significant  federal and state  regulation,
which  may affect rates of return on  such investments and the kinds of services
that may be offered.
 
                  Statement of Additional Information Page 29
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
 
Competition is intense for many natural  resources companies. As a result,  many
of  these companies may be adversely affected in the future and the value of the
securities by such companies may be subject to increased share price volatility.
Such companies may also be subject to irregular fluctuations in earnings due  to
changes  in the availability  of money, the  level of interest  rates, and other
factors.
 
The value  of  securities  of  natural resources  companies  will  fluctuate  in
response  to market conditions  for the particular  natural resources with which
the issuers are involved. The price  of natural resources will fluctuate due  to
changes  in worldwide levels of inventory,  and changes, perceived or actual, in
production  and  consumption.  With  respect  to  precious  metals,  such  price
fluctuations  may be  substantial over short  periods of time.  In addition, the
value of natural resources may fluctuate directly with respect to various stages
of the inflationary cycle and perceived  inflationary trends and are subject  to
numerous factors, including national and international politics.
 
    THE TELECOMMUNICATIONS FUND. An example of the regulatory environment of the
companies in which the Funds invests is that of telephone operating companies in
the  United  States, which  are  subject to  both  federal and  state regulation
affecting permitted  rates of  return and  the  kinds of  services that  may  be
offered.  Certain  types of  companies  in the  telecommunications  industry are
engaged in fierce competition  for market share that  could result in  increased
share price volatility.
 
    MONEY  MARKET FUND. In periods of declining interest rates, the Fund's yield
will tend to  be somewhat higher  than prevailing market  rates; conversely,  in
periods  of rising  interest rates,  the Fund's yield  will tend  to be somewhat
lower than those  rates. Also, when  interest rates are  falling, the new  money
flowing into the Fund from the net sale of its shares likely will be invested by
the  Fund  in  instruments  producing  lower  yields  than  the  balance  of the
securities held  by  the  Fund's  portfolio, thereby  reducing  its  yield.  The
opposite generally will be true in periods of rising interest rates. The Fund is
designed  to provide  maximum current income  consistent with  the liquidity and
safety afforded  by investment  in  a portfolio  of  high quality  money  market
instruments; the Fund's yield may be lower than that produced by funds investing
in lower quality and/or longer-term securities.
 
ILLIQUID SECURITIES
Each  Fund may invest up to  15% of its net assets  (except for the Money Market
Fund, which may  invest up to  10% of  its net assets)  in illiquid  securities.
Securities  may be considered illiquid if a Fund cannot reasonably expect within
seven days to sell the securities for approximately the amount at which the Fund
values such  securities.  See "Investment  Limitations."  The sale  of  illiquid
securities  if they  can be sold  at all,  generally will require  more time and
result in  higher  brokerage  charges  or dealer  discounts  and  other  selling
expenses  than the  sale of  liquid securities  such as  securities eligible for
trading  on  securities  exchanges  or  in  OTC  markets.  Moreover,  restricted
securities,  which may be illiquid for  purposes of this limitation, often sell,
if at all,  at a price  lower than similar  securities that are  not subject  to
restrictions on resale.
 
Illiquid  securities include those that are subject to restrictions contained in
the securities  laws of  other countries.  However, securities  that are  freely
marketable  in the country where  they are principally traded,  but would not be
freely marketable in the United States,  will not be considered illiquid.  Where
registration  is required, the Fund  may be obligated to pay  all or part of the
registration expenses and a considerable period  may elapse between the time  of
the  decision to sell and the time the  Fund may be permitted to sell a security
under an effective  registration statement.  If, during such  a period,  adverse
market  conditions were to develop, the Fund might obtain a less favorable price
than prevailed when it decided to sell.
 
Not  all  restricted  securities   are  illiquid.  In   recent  years  a   large
institutional   market  has  developed  for  certain  securities  that  are  not
registered under the Securities Act of 1933, as amended ("1933 Act"),  including
private  placements, repurchase agreements, commercial paper, foreign securities
and corporate bonds and notes. These instruments are often restricted securities
because the  securities are  sold in  transactions not  requiring  registration.
Institutional investors generally will not seek to sell these instruments to the
general   public,  but  instead  will  often   depend  either  on  an  efficient
institutional market in which such unregistered securities can be readily resold
or on an issuer's ability to honor  a demand for repayment. Therefore, the  fact
that there are contractual or legal restrictions on resale to the general public
or certain institutions is not dispositive of the liquidity of such investments.
 
Rule  144A under the 1933 Act establishes  a "safe harbor" from the registration
requirements of the  1933 Act  for resales  of certain  securities to  qualified
institutional  buyers.  Institutional  markets  for  restricted  securities have
developed as a result of Rule 144A, providing both readily ascertainable  values
for  restricted securities and the ability to liquidate an investment to satisfy
share redemption orders. Such  markets might include  automated systems for  the
trading,  clearance and  settlement of  unregistered securities  of domestic and
foreign issuers, such as the PORTAL System sponsored by the National Association
of Securities Dealers,  Inc. An insufficient  number of qualified  institutional
buyers interested in
 
                  Statement of Additional Information Page 30
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
purchasing  Rule 144A-eligible restricted securities held by the Funds, however,
could affect adversely the  marketability of such  portfolio securities and  the
Funds  might be unable  to dispose of  such securities promptly  or at favorable
prices.
 
With respect  to  liquidity  determinations  generally,  a  Company's  Board  of
Trustees  has  the  ultimate  responsibility  for  determining  whether specific
securities, including restricted securities pursuant to Rule 144A under the 1933
Act, are liquid  or illiquid. Each  Board has delegated  the function of  making
day-to-day  determinations of liquidity  to the Sub-advisor,  in accordance with
procedures approved by that Board. AIM and/or the sub-advisors take into account
a number of factors in reaching liquidity decisions, including, but not  limited
to:  (i) the frequency  of trading in  the security; (ii)  the number of dealers
that make  quotes  for  the security;  (iii)  the  number of  dealers  who  have
undertaken  to make a market in the security; (iv) the number of other potential
purchasers; and  (v) the  nature of  the security  and how  trading is  effected
(e.g.,  the time needed to sell the  security, how offers are solicited, and the
mechanics of transfer).  AIM and/or  the sub-advisors monitor  the liquidity  of
securities  held by each Fund and periodically report such determinations to the
Companies' Boards of Trustees. If the liquidity percentage restriction of a Fund
is satisfied at the time  of investment, a later  increase in the percentage  of
illiquid  securities held by the Fund resulting from a change in market value or
assets will not constitute a violation of that restriction. If as a result of  a
change  in market value or assets, the percentage of illiquid securities held by
the Fund increases above the applicable limit, AIM and/or the sub-advisors  will
take  appropriate steps  to bring the  aggregate amount of  illiquid assets back
within the prescribed limitations as soon as reasonably practicable, taking into
account the effect of any disposition on the Fund.
 
The Infrastructure Fund, the Natural Resources Fund, the Telecommunications Fund
and  the  Latin  America  Fund  may  invest  in  joint  ventures,  cooperatives,
partnerships  and state  enterprises which are  illiquid (collectively, "Special
Situations"). AIM  and/or the  sub-advisors believe  that investments  by  these
Funds  in Special Situations  could enable them  to achieve capital appreciation
substantially exceeding the appreciation each Fund  would realize if it did  not
make such investments. However, in order to limit investment risk, each of these
Funds will invest no more than 5% of its total assets in Special Situations.
 
FOREIGN SECURITIES
    POLITICAL,  SOCIAL AND ECONOMIC  RISKS. Investing in  securities of non-U.S.
companies may entail additional risks due to the potential political, social and
economic instability  of  certain  countries and  the  risks  of  expropriation,
nationalization,  confiscation  or  the imposition  of  restrictions  on foreign
investment; convertibility of currencies into  U.S. dollars and on  repatriation
of  capital invested.  In the  event of  such expropriation,  nationalization or
other confiscation by any  country, a Fund could  lose its entire investment  in
any   such  country.  Individual  foreign  economies  may  differ  favorably  or
unfavorably from the U.S. economy in  such respects as growth of gross  national
product, rates of inflation, rates of savings and capital reinvestment, resource
self sufficiency and balance of payments positions.
 
    RELIGIOUS,  POLITICAL, OR ETHNIC  INSTABILITY. Certain countries  in which a
Fund may invest may have groups that advocate radical religious or revolutionary
philosophies or support ethnic independence. Any disturbance on the part of such
individuals could carry the potential for widespread destruction or confiscation
of property owned by individuals and entities foreign to such country and  could
cause  the loss of a Fund's investment  in those countries. Instability may also
result from,  among  other things:  (i)  authoritarian governments  or  military
involvement  in  political and  economic  decision-making, including  changes in
government through extra-constitutional  means; (ii)  popular unrest  associated
with  demands for improved political, economic  and social conditions; and (iii)
hostile relations with  neighboring or other  countries. Such political,  social
and  economic instability could disrupt the principal financial markets in which
the Fund invests and adversely affect the value of a Fund's assets.
 
    FOREIGN  INVESTMENT  RESTRICTIONS.  Certain  countries  prohibit  or  impose
substantial  restrictions on investments in  their capital markets, particularly
their equity markets, by foreign entities such as a Fund. These restrictions  or
controls may at times limit or preclude investment in certain securities and may
increase the cost and expenses of a Fund. For example, certain countries require
prior governmental approval before to investments by foreign persons maybe made,
or may limit the amount of investment by foreign persons in a particular company
or  limit  the  investment  by  foreign persons  to  only  a  specific  class of
securities of a company that may have less advantageous terms than securities of
the company available for purchase by nationals. Moreover, the national policies
of certain  countries  may  restrict  investment  opportunities  in  issuers  or
industries  deemed sensitive to national  interests. In addition, some countries
require governmental approval for the repatriation of investment income, capital
or the proceeds of securities sales by foreign investors. In addition, if  there
is  a deterioration in a  country's balance of payments  or for other reasons, a
country may impose restrictions  on foreign capital  remittances abroad. A  Fund
could  be adversely affected by  delays in, or a  refusal to grant, any required
governmental approval for repatriation, as well  as by the application to it  of
other restrictions on investments.

                      GT GLOBAL VARIABLE INVESTMENT FUNDS
 
    NON-UNIFORM CORPORATE DISCLOSURE STANDARDS AND GOVERNMENTAL
REGULATION.  Foreign companies are subject to accounting, auditing and financial
standards and requirements that differ, in some cases significantly, from  those
applicable to U.S. companies. In particular, the assets, liabilities and profits
appearing  on the  financial statements  of such a  company may  not reflect its
financial position or results of operations  in the way they would be  reflected
had  such financial statements  been prepared in  accordance with U.S. generally
accepted accounting principles. Most  of the foreign securities  held by a  Fund
will  not be registered with  the SEC or regulators  of any foreign country, nor
will the issuers thereof be subject  to the SEC's reporting requirements.  Thus,
there   will  be  less  available  information  concerning  foreign  issuers  of
securities held  by the  Fund  than is  available  concerning U.S.  issuers.  In
instances  where the financial statements of an issuer are not deemed to reflect
accurately the financial situation  of the issuer,  AIM and/or the  sub-advisors
will  take  appropriate steps  to evaluate  the  proposed investment,  which may
include on-site inspection  of the  issuer, interviews with  its management  and
consultations   with  accountants,  bankers  and  other  specialists.  There  is
substantially less publicly available  information about foreign companies  than
there  are  reports and  ratings  published about  U.S.  companies and  the U.S.
government. In addition, where public information  is available, it may be  less
reliable  than such information regarding U.S. issuers. Issuers of securities in
foreign jurisdictions are generally not subject to the same degree of regulation
as are  U.S. issuers  with respect  to such  matters as  restrictions on  market
manipulation,  insider trading rules, shareholder  proxy requirements and timely
disclosure of information.
 
    CURRENCY FLUCTUATIONS. Because each Fund under normal circumstances  (except
the  Money Market Fund and  to a lesser extent, the  America Fund) will invest a
substantial portion of  its total assets  in the securities  of foreign  issuers
which  are denominated  in foreign currencies,  the strength or  weakness of the
U.S. dollar against such  foreign currencies will account  for part of a  Fund's
investment  performance.  A  decline in  the  value of  any  particular currency
against the U.S.  dollar will  cause a  decline in the  U.S. dollar  value of  a
Fund's  holdings  of  securities  and cash  denominated  in  such  currency and,
therefore, will cause an overall decline in  the Fund's net asset value and  any
net  investment  income and  capital gains  derived from  such securities  to be
distributed in U.S. dollars to shareholders in the Fund. Moreover, if the  value
of  the foreign currencies in which a Fund receives its income falls relative to
the  U.S.  dollar  between  receipt  of  the  income  and  the  making  of  Fund
distributions, the Fund may be required to liquidate securities in order to make
distributions  if  the  Fund  has  insufficient cash  in  U.S.  dollars  to meet
distribution requirements.
 
The rate of exchange between the U.S. dollar and other currencies is  determined
by  several factors including  the supply and  demand for particular currencies,
central bank efforts to support particular currencies, the relative movement  of
interest  rates, the pace of  business activity in the  other countries, and the
United States, and other economic  and financial conditions affecting the  world
economy.
 
Austria,  Belgium,  Finland, France,  Germany,  Ireland, Italy,  Luxembourg, the
Netherlands, Portugal,  and  Spain are  members  of the  European  Economic  and
Monetary  Union (the "EMU"). The EMU  has established a common European currency
for participating countries  which is  known as the  "euro." Each  participating
country supplemented its existing currency with the euro on January 1, 1999, and
it  is anticipated  that each  participating country  will replace  its existing
currency with the euro  on July 1,  2002. Any other European  country that is  a
member of the European Union and satisfies the criteria for participation in the
EMU,  may  elect to  participate  in the  EMU  and may  supplement  its existing
currency with the euro after January 1, 1999.
 
The introduction of the euro presents unique risks and uncertainties,  including
how  outstanding financial contracts will be  treated after January 1, 1999; the
establishment of exchange rates  for existing currencies and  the euro; and  the
creation  of suitable  clearing and settlement  systems for the  euro. These and
other factors could cause market disruptions before or after the introduction of
the euro and could adversely affect the value of securities held by the Fund.
 
Although each Fund values its assets daily  in terms of U.S. dollars, the  Funds
do  not intend to convert their holdings of foreign currencies into U.S. dollars
on a daily basis. Each Fund will do so, from time to time, and investors  should
be  aware of the costs of currency conversion. Although foreign exchange dealers
do not  charge a  fee for  conversion, they  do realize  a profit  based on  the
difference  ("spread") between  the prices  at which  they buy  and sell various
currencies. Thus, a dealer may offer to sell a foreign currency to a Fund at one
rate, while offering a lesser rate of exchange should a Fund desire to sell that
currency to the dealer.
 
    ADVERSE MARKET CHARACTERISTICS.  Securities of many  foreign issuers may  be
less  liquid and their  prices more volatile than  securities of comparable U.S.
issuers. In  addition,  foreign securities  markets  and brokers  generally  are
subject  to  less governmental  supervision and  regulation  than in  the United
States, and  foreign  securities  transactions  usually  are  subject  to  fixed
commissions,  which  generally are  higher than  negotiated commissions  on U.S.
transactions. In addition,  foreign securities  transactions may  be subject  to
difficulties  associated  with the  settlement of  such transactions.  Delays in
settlement could  result  in  temporary  periods  when  assets  of  a  Fund  are
uninvested and no return is earned thereon. The
 
                  Statement of Additional Information Page 32
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
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  a security  due to  settlement problems  either could
result in losses to a Fund due to subsequent declines in value of that  security
or,  if a Fund has entered into a contract to sell the security, could result in
possible liability to the purchaser.  AIM and/or the sub-advisors will  consider
such  difficulties  when  determining  the  allocation  of  each  Fund's assets,
although AIM and/or the sub-advisors do not believe that such difficulties  will
have a material adverse effect on a Fund's trading activities.
 
The  risk  also exists  that an  emergency situation  may arise  in one  or more
emerging markets as a result of which trading of securities may cease or may  be
substantially  curtailed and  prices for a  Fund's portfolio  securities in such
markets may not be readily  available. Section 22(e) of  the 1940 Act permits  a
registered  investment  company  to suspend  redemption  of its  shares  for any
period, during which an emergency exists, as determined by the SEC. Accordingly,
if a  Fund believes  that appropriate  circumstances warrant,  it will  promptly
apply to the SEC for a determination that an emergency exists within the meaning
of  Section 22(e) of  the 1940 Act.  During the period  commencing from a Fund's
identification of  such conditions  until the  date of  SEC action,  the  Fund's
portfolio  securities in the  affected markets will  be valued at  fair value as
determined in good  faith by or  under the direction  of the relevant  Company's
Board of Trustees.
 
In  certain markets there have  been times when settlements  have been unable to
keep pace with  the volume of  securities transactions, making  it difficult  to
conduct  such transactions. The inability of  a Fund to make intended securities
purchases due to settlement problems could  cause the Fund to forego  attractive
investment  opportunities. Inability to  dispose of a  portfolio security caused
settlement problems 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  to  the
purchaser.
 
Each  Fund may use  foreign custodians, which  may involve risks  in addition to
those related to the  use of U.S. custodians.  Such risks include  uncertainties
relating  to  determining  and  monitoring  the  foreign  custodian's  financial
strength, reputation and standing; maintaining appropriate safeguards concerning
the Fund's investments;  and possible  difficulties in  obtaining and  enforcing
judgments against such custodians.
 
    WITHHOLDING  TAXES. A Fund's net investment  income from foreign issuers may
be subject  to  withholding  taxes  by the  foreign  issuer's  country,  thereby
reducing the Fund's net investment income or delaying the receipt of income when
those taxes may be recaptured. See "Taxes."
 
    CONCENTRATION.  To the  extent a Fund  invests a significant  portion of its
assets in securities of issuers located in a particular country or region of the
world, such Fund  may be  subject to greater  risks and  may experience  greater
volatility than a fund that is more broadly diversified geographically.
 
    SPECIAL  CONSIDERATIONS AFFECTING WESTERN  EUROPEAN COUNTRIES. The countries
that are members of the European Economic Community ("Common Market")  (Austria,
Belgium,  Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg,
the Netherlands,  Portugal, Spain,  Sweden and  the United  Kingdom)  eliminated
certain  import tariffs and quotas and other  trade barriers with respect to one
another over the past  several years. AIM and/or  the sub-advisors believe  that
this  deregulation  should improve  the prospects  for  economic growth  in many
Western European countries.  Among other things,  the deregulation could  enable
companies  domiciled in  one country  to avail  themselves of  lower labor costs
existing in  other  countries.  In addition,  this  deregulation  could  benefit
companies domiciled in one country by opening additional markets for their goods
and  services in other countries. Since, however, it is not clear what the exact
form or effect of  these Common Market  reforms will be  on business in  Western
Europe,  it is impossible to predict  the long-term impact of the implementation
of these programs on the securities owned by a Fund.
 
    SPECIAL CONSIDERATIONS  AFFECTING  RUSSIA AND  EASTERN  EUROPEAN  COUNTRIES.
Investing  in Russia  and Eastern European  countries involves a  high degree of
risk and special considerations not  typically associated with investing in  the
United  States securities markets, and  should be considered highly speculative.
Such risks include: (1)  delays in settling portfolio  transactions and risk  of
loss  arising out of the system of  share registration and custody; (2) the risk
that it may be impossible  or more difficult than  in other countries to  obtain
and/or  enforce a  judgement; (3) pervasiveness  of corruption and  crime in the
economic system; (4) currency exchange rate volatility and the lack of available
currency hedging instruments; (5) higher rates of inflation (including the  risk
of   social  unrest  associated  with   periods  of  hyper-inflation)  and  high
unemployment; (6) controls on foreign investment and local practices disfavoring
foreign investors and limitations on  repatriation of invested capital,  profits
and  dividends, and on  a fund's ability  to exchange local  currencies for U.S.
dollars; (7) political instability and social unrest and violence; (8) the  risk
that  the governments of Russia and Eastern European countries may decide not to
continue to support the economic reform programs implemented recently and  could
follow  radically different political and/or  economic policies to the detriment
of investors, including non-market-

                      GT GLOBAL VARIABLE INVESTMENT FUNDS
oriented policies such as  the support of certain  industries at the expense  of
other  sectors or investors, or  a return to the  centrally planned economy that
existed when  such  countries  had  a communist  form  of  government;  (9)  the
financial  condition of companies in these countries, including large amounts of
inter-company debt which may create a payments crisis on a national scale;  (10)
dependency  on exports and the  corresponding importance of international trade;
(11) the risk that  the tax system  in these countries will  not be reformed  to
prevent  inconsistent,  retroactive  and/or exorbitant  taxation;  and  (12) the
underdeveloped nature of the securities markets.
 
    SPECIAL CONSIDERATIONS AFFECTING JAPAN. Japan's economic growth has declined
significantly since 1990. The general government position has deteriorated as  a
result  of weakening economic  growth and stimulative  measures taken to support
economic activity and to  restore financial stability.  Although the decline  in
interest   rates  and  fiscal  stimulation   packages  have  helped  to  contain
recessionary forces, uncertainties remain. Japan is also heavily dependent  upon
international  trade, so its  economy is especially  sensitive to trade barriers
and disputes.  Japan has  had  difficult relations  with its  trading  partners,
particularly the United States, where the trade imbalance is the greatest. It is
possible  that  trade sanctions  and other  protectionist measures  could impact
Japan adversely in both the short and the long term.
 
The common  stocks  of many  Japanese  companies trade  at  high  price-earnings
ratios.  Differences  in accounting  methods make  it  difficult to  compare the
earnings of  Japanese companies  with  those of  companies in  other  countries,
especially  in the  U.S. In  general, however, reported  net income  in Japan is
understated relative to  U.S. accounting standards  and this is  one reason  why
price-earnings   ratios  of  the  stocks   of  Japanese  companies  have  tended
historically to be  higher than  those for  U.S. stocks.  In addition,  Japanese
companies  have  tended to  have  higher growth  rates  than U.S.  companies and
Japanese interest rates  have generally  been lower than  in the  U.S., both  of
which  factors tend to result in  lower discount rates and higher price-earnings
ratios in Japan than in the U.S.
 
The Japanese securities  markets are  less regulated  than those  in the  United
States. Evidence has emerged from time to time of distortion of market prices to
serve  political or other purposes. Shareholders'  rights are not always equally
enforced. In addition, Japan's banking  industry is undergoing problems  related
to bad loans and declining values in real estate.
 
    SPECIAL  CONSIDERATIONS AFFECTING  PACIFIC REGION COUNTRIES.  Certain of the
risks associated with international  investments are heightened for  investments
in  Pacific region  countries. For  example, some  of the  currencies at Pacific
region countries  have  experienced steady  devaluations  relative to  the  U.S.
dollar,  and major  adjustments have been  made periodically in  certain of such
currencies. Certain countries, such as India, face serious exchange constraints.
Many of the Asia Pacific region countries may be subject to a greater degree  of
social,  political  and economic  instability  than is  the  case in  the United
States. Such instability may result from, among other things, the following: (i)
authoritarian governments  or military  involvement  in political  and  economic
decision  making, and changes in  government through extra-constitutional means;
(ii) popular unrest associated with demands for improved political, economic and
social conditions;  (iii) internal  insurgencies;  (iv) hostile  relations  with
neighboring  countries; and (v) ethnic,  religious and racial disaffection. Such
social, political  and  economic  instability could  significantly  disrupt  the
principal  financial markets  in which a  Fund invests and  adversely affect the
value of a Fund's  assets. In addition,  there may be  the possibility of  asset
expropriations or future confiscatory levels of taxation affecting the Funds.
 
In  China, India, Indonesia,  Malaysia, the Philippines,  Singapore, South Korea
and Thailand, government regulation or a company's charter may limit the maximum
foreign aggregate ownership of equity in any one company. South Korea  generally
prohibits  foreign investment in  Won-denominated debt securities  and Sri Lanka
prohibits  foreign  investment  in  government  debt  securities.  South   Korea
prohibits  foreign investment in specified  telecommunications companies and the
Philippines prohibits foreign investment in  mass media companies and  companies
providing  certain  professional  services.  In  the  Philippines,  a  Fund  may
generally  invest  in  "B"  shares  of  Philippine  issuers  engaged  in  partly
nationalized  business activities,  the market  prices, liquidity  and rights of
which may vary from shares owned by  nationals. Similarly, in China, a Fund  may
only  invest  in "B"  shares  of securities  traded  on The  Shanghai Securities
Exchange  and  The  Shenzhen  Stock  Exchange,  currently  the  two   officially
recognized  securities exchanges  in China.  "B" shares  traded on  The Shanghai
Securities Exchange  are  settled in  U.S.  dollars,  and those  traded  on  The
Shenzhen Stock Exchange are generally settled in Hong Kong dollars.
 
If, because of restrictions on repatriation or conversion, a Fund were unable to
distribute  substantially all of its net investment income and net capital gains
within applicable time periods, the Fund could be subject to federal income  tax
that  would  not  otherwise be  incurred  and  could cease  to  qualify  for the
favorable tax  treatment afforded  to  regulated investment  companies  ("RICs")
under  the Internal Revenue Code of 1986,  as amended ("Code"). In such case, it
would become subject to federal income tax on all of its income and net  capital
gains.

Several  of  the Asia  Pacific region  countries have  or in  the past  have had
hostile relationships  with neighboring  nations  or have  experienced  internal
insurgency.  Thailand has experienced  border conflicts with  Laos and Cambodia,
and India is engaged in border disputes with several of its neighbors, including
China and Pakistan. An uneasy truce exists between North Korea and South  Korea,
and the recurrence of hostilities remains possible. Reunification of North Korea
and  South Korea could have a detrimental  effect on the economy of South Korea.
Also, China continues  to claim sovereignty  over Taiwan and  has, in the  past,
conducted military maneuvers near Taiwan.
 
The economies of most of the Asia Pacific region countries are heavily dependent
upon  international  trade  and  are accordingly  affected  by  protective trade
barriers and the economic conditions of their trading partners, principally  the
United  States, Japan,  China and the  European Community. The  enactment by the
United States  or  other  principal  trading  partners  of  protectionist  trade
legislation,  reduction of foreign investment in the local economies and general
declines in  the  international  securities markets  could  have  a  significant
adverse effect upon the securities markets of the Asia Pacific region countries.
In  addition,  the  economies of  some  of  the Asia  Pacific  region countries,
Australia and Indonesia, for example, are vulnerable to weakness in world prices
for their commodity exports, including crude oil.
 
Few of the Asia Pacific region countries have Western-style or fully  democratic
governments.  Some governments  in the  region are  authoritarian in  nature and
influenced by security  forces. For example,  during the course  of the last  25
years,  governments in the region have been  installed or removed as a result of
military coups, while  others have periodically  demonstrated repressive  police
state  characteristics. In several Asia Pacific Region countries, the leadership
ability of  the  government  has  suffered as  a  result  of  recent  corruption
scandals.  Disparities of wealth,  among other factors, have  also led to social
unrest in some  of the Asia  Pacific region countries,  accompanied, in  certain
cases,  by violence and labor unrest. Ethnic, religious and racial disaffection,
as evidenced  in India,  Pakistan,  and Sri  Lanka,  for example,  have  created
social,  economic and  political problems. Such  problems also  have occurred in
other regions.
 
Starting in mid-1997, some Pacific region countries began to experience currency
devaluations that resulted in high interest rate levels and sharp reductions  in
economic activity. While the currency crisis diminished prospects for short-term
corporate  earnings  growth, the  Sub-advisor believes  that high  interest rate
levels may  force  governments and  corporations  to restructure  the  financial
sector  in a  manner that may  facilitate a  return to high  levels of long-term
economic activity.
 
China assumed  sovereignty over  Hong  Kong in  July  1997. Although  China  has
committed by treaty to preserve the economic and social freedoms enjoyed in Hong
Kong  for fifty years after regaining control  of Hong Kong, the continuation of
the current form of the  economic system in Hong  Kong after the reversion  will
depend  on the actions of  the government of China.  In addition, such reversion
has increased sensitivity in Hong Kong to political developments and  statements
by  public figures in China. Business confidence in Hong Kong, therefore, can be
significantly affected by such  developments and statements,  which in turn  can
affect markets and business performance.
 
In  addition, the Chinese sovereignty  over Hong Kong also  presents a risk that
the Hong Kong dollar will be devaluated and a risk of possible loss of  investor
confidence  in the Hong Kong markets and dollar. However, factors exist that are
likely to mitigate this risk. First, China has stated its intention to implement
a "one country, two systems"  policy, which would preserve monetary  sovereignty
and leave control in the hands of the Hong Kong Monetary Authority ("HKMA").
 
Second,  fixed  rate  parity  with  the  U.S.  dollar  is  seen  as  critical to
maintaining investors'  confidence  in  the  transition  to  Chinese  rule  and,
therefore,  it is  anticipated that, in  the event  international investors lose
confidence in Hong Kong dollar assets,  the HKMA would intervene to support  the
currency,  though such  intervention cannot be  assured. Third,  Hong Kong's and
China's sizable combined  foreign exchange reserve  may be used  to support  the
value  of the Hong  Kong dollar, provided  that China does  not appropriate such
reserves for  other uses,  which  is not  anticipated,  but cannot  be  assured.
Finally,  China would be likely to  experience significant adverse political and
economic consequences if confidence  in the Hong Kong  dollar and the  territory
assets were to be endangered.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  LATIN  AMERICAN  COUNTRIES.  Most  Latin
American countries have experienced substantial,  and in some periods  extremely
high,  rates of  inflation for many  years. Inflation and  rapid fluctuations in
inflation rates have had and may continue  to have very negative effects on  the
economies  and securities markets  of certain Latin  American countries. Certain
Latin American countries are also among the largest debtors to commercial  banks
and foreign governments. At times certain Latin American countries have declared
moratoria  on  the payment  of principal  and/or interest  on external  debt. In
addition, certain  Latin  American  securities  markets  have  experienced  high
volatility in recent years.
 
Latin  American countries may  also close certain sectors  of their economies to
equity investments  by foreigners.  Further  due to  the absence  of  securities
markets  and  publicly  owned corporations  and  due to  restrictions  on direct
investment by
 
                  Statement of Additional Information Page 35
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
foreign entities,  investments  may  only  be made  in  certain  Latin  American
countries   solely  or  primarily  through  governmentally  approved  investment
vehicles or companies.
 
Certain Latin American countries may have managed currencies that are maintained
at artificial levels to the U.S. dollar rather than at levels determined by  the
market.  This type  of system can  lead to  sudden and large  adjustments in the
currency which, in turn,  can have a disruptive  and negative effect on  foreign
investors.  For example, in late  1994, the value of  the Mexican peso lost more
than one-third of its value relative to the U.S. dollar.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  EMERGING   MARKETS.  Investing  in   the
securities of companies in emerging markets may entail special risks relating to
potential  political and  economic instability  and the  risks of expropriation,
nationalization, confiscation  or  the  imposition of  restrictions  on  foreign
investment,  convertibility  into U.S.  dollars and  on repatriation  of capital
invested.  In  the  event  of  such  expropriation,  nationalization  or   other
confiscation by any country, a Fund could lose its entire investment in any such
country.
 
Emerging  securities  markets are  substantially  smaller, less  developed, less
liquid and more volatile than the major securities markets. The limited size  of
emerging securities markets and limited trading value in issuers compared to the
volume  of  trading in  U.S. securities  could  cause prices  to be  erratic for
reasons apart  from factors  that  affect the  quality  of the  securities.  For
example, limited market size may cause prices to be unduly influenced by traders
who  control  large  positions. Adverse  publicity  and  investors' perceptions,
whether or  not  based on  fundamental  analysis,  may decrease  the  value  and
liquidity  of portfolio  securities, especially  in these  markets. In addition,
securities traded in certain emerging markets may be subject to risks due to the
inexperience of financial intermediaries, a lack of modern technology, the  lack
of  a sufficient capital base to expand business operations, and the possibility
of permanent or temporary termination of trading.
 
Economies in emerging markets generally are heavily dependent upon international
trade and, accordingly, have been and  may continue to be adversely affected  by
trade  barriers,  exchange controls,  managed  adjustments in  relative currency
values and other protectionist measures  imposed or negotiated by the  countries
with  which they trade.  These economies also  have been and  may continue to be
affected by economic conditions in the countries in which they trade.
 
Settlement mechanisms in emerging securities  markets may be less efficient  and
reliable  than in more developed markets.  In such emerging securities there may
be share registration and delivery delays or failures.
 
Many emerging market countries have experienced substantial, and in some periods
extremely  high,  rates  of  inflation  for  many  years.  Inflation  and  rapid
fluctuations in inflation rates and corresponding currency devaluations have had
and  may  continue to  have  negative effects  on  the economies  and securities
markets of certain emerging market countries.
 
    LOWER QUALITY  DEBT  SECURITIES. There  are  no credit  quality  limitations
placed  on the debt  securities in which  the Latin America  Fund may invest. In
addition, the Infrastructure Fund, the  Natural Resources Fund and the  Emerging
Markets   Fund  may   each  invest   up  to  20%   of  its   total  assets,  the
Telecommunications Fund may  invest up to  5% of its  assets, and the  Strategic
Income  Fund may invest up to 50% of  its assets, in below investment grade debt
securities. Finally, each Global Growth Fund may invest up to 35% of its  assets
in  debt securities rated no lower  than investment grade. Investment grade debt
securities are debt securities rated  BBB or higher by S&P  or Baa or higher  by
Moody's  or, if unrated, deemed  to be of equivalent  quality in the judgment of
AIM and/or the sub-advisors.
 
Debt rated  Baa  by  Moody's  is  considered  by  Moody's  to  have  speculative
characteristics. Debt rated BB, B, CCC, CC and C by S&P or debt securities rated
Ba,  B,  Caa, Ca  or  C by  Moody's is  regarded,  on balance,  as predominantly
speculative with respect  to the  issuer's capacity  to pay  interest and  repay
principal  in  accordance with  the terms  of the  obligation. While  such lower
quality debt will likely have some quality and protective characteristics, these
are outweighed  by  large  uncertainties  or major  risk  exposures  to  adverse
conditions.  Debt rated C by Moody's or S&P is the lowest rated debt that is not
in default as to principal or interest, and such issues so rated can be regarded
as having  extremely  poor  prospects  of ever  attaining  any  real  investment
standing.  Lower quality  debt securities  are also  generally considered  to be
subject to greater  risk than securities  with higher ratings  with regard to  a
deterioration   of  general  economic  conditions.   These  lower  quality  debt
securities are the equivalent of high yield, high risk bonds, commonly known  as
"junk  bonds." The Infrastructure  Fund and the Natural  Resources Fund will not
invest in securities in default as to principal and interest.
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to  evaluate
the  safety of principal and interest payments  and do not evaluate the risks of
fluctuations in market  value. Also,  rating agencies  may fail  to make  timely
changes  in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates.  See
"Description of Debt Ratings", below, for a full discussion of Moody's and S&P's
ratings.
 
                  Statement of Additional Information Page 36
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
 
Issuers  of lower quality securities are often highly leveraged and may not have
available to them more traditional methods of financing. For example, during  an
economic  downturn  or  a  sustained period  of  rising  interest  rates, highly
leveraged issuers of lower quality  securities may experience financial  stress.
During such periods, such issuers may not have sufficient revenues to meet their
interest   payment  obligations.  The  issuer's  ability  to  service  its  debt
obligations may also  be adversely affected  by specific developments  affecting
the  issuer, such as the issuer's  inability to meet specific projected business
forecasts or the unavailability of additional financing. The risk of loss due to
default by the issuer is significantly greater for the holders of lower  quality
securities   because  such  securities  are   generally  unsecured  and  may  be
subordinated to the claims of other creditors of the issuer.
 
Lower quality  debt securities  of  corporate issuers  frequently have  call  or
buy-back  features  which  would permit  an  issuer  to call  or  repurchase the
security from a  Fund. If an  issuer exercises these  provisions in a  declining
interest  rate market,  a Fund  may have  to replace  the security  with a lower
yielding security, resulting in a decreased return for investors. In addition, a
Fund may have difficulty disposing of lower quality securities because they  may
have  a thin trading market. There may be no established retail secondary market
for many  of these  securities, and  each  of the  Funds anticipates  that  such
securities  could be sold only  to a limited number  of dealers or institutional
investors. The lack of a liquid secondary market also may have an adverse impact
on market prices of such instruments and  may make it more difficult for a  Fund
to  obtain  accurate  market  quotations  for  purposes  of  valuing  the Fund's
portfolio investments. The Infrastructure Fund, the Natural Resources Fund,  the
Telecommunications  Fund and  the Strategic Income  Fund may  also acquire lower
quality debt securities during an initial underwriting or which are sold without
registration under applicable securities  laws. Such securities involve  special
considerations and risks.
 
In  addition to the foregoing, factors that  could have an adverse effect on the
market value  of lower  rated debt  securities  in which  the Funds  may  invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic  recession. The Funds may also  incur additional expenses to the extent
they are required to seek recovery upon a default in the payment of principal or
interest on portfolio holdings, and the Funds may have limited legal recourse in
the event of a default.
 
As of December 31, 1997, the Strategic  Income Fund had 89.11% of its total  net
assets invested in debt securities that received a rating from Moody's and 2.98%
of  its total net assets invested in debt  securities that were not so rated. In
addition, the Strategic Income Fund  had 7.91% of its  total net assets in  cash
and  net receivables. The Strategic Income Fund had the following percentages of
its total  net  assets invested  in  rated securities:  Aaa--42.44%,  Aa--9.62%,
A--1.04%,  Baa--3.37%, Ba--18.37%,  B--12.27%, Caa--0.00%,  Ca--0.00%, C--0.00%.
Included under  the  unrated category  are  securities composing  2.98%  of  the
Strategic  Income  Fund's  total  net assets  which,  while  unrated,  have been
determined by the Sub-advisor to be  of comparable quality to securities in  the
following   rating  categories:  Ba--0.96%,  B--2.02%.  The  allocation  of  the
investments of the Strategic Income Fund by  rating on any given date will  vary
and  should  not be  considered representative  of  the Strategic  Income Fund's
future portfolio composition.
 
    SOVEREIGN DEBT. Periods of economic uncertainty may result in the volatility
of market prices of sovereign debt obligations and, in turn, a Fund's net  asset
value, to a greater extent than the volatility inherent in domestic fixed income
securities.
 
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 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
principal international  lenders  and the  political  constraints to  which  the
sovereign  debtor may be  subject. Emerging market  governments could default on
their Sovereign Debt. Such sovereign debtors  also may be dependent on  expected
disbursements from foreign governments, multilateral agencies and other entities
abroad to reduce principal and interest arrearages on their debt. The commitment
on the part of these governments, agencies and others to make such disbursements
may  be conditioned on  a sovereign debtor's  implementation of economic reforms
and/or economic performance and the timely service of such debtor's obligations.
Failure to implement such reforms,  achieve such levels of economic  performance
or  repay principal or interest when due, may result in the cancellation of such
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.
 
The  occurrence of political, social or diplomatic changes in one or more of the
countries issuing sovereign  debt could adversely  affect a Fund's  investments.
Emerging  markets are faced with  social and political issues,  and some of them
have experienced high  rates of  inflation in  recent years  and have  extensive
internal  debt. Among  other effects, high  inflation and  internal debt service
requirements may adversely affect the  cost and availability of future  domestic
sovereign borrowing to finance governmental programs, and may have other adverse
social, political and economic consequences.
 
                  Statement of Additional Information Page 37
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
Political  changes or a deterioration of a country's domestic economy or balance
of trade may  affect the  willingness of  countries to  service their  sovereign
debt.  Although  the Sub-advisor  intends to  manage the  respective Funds  in a
manner that will minimize the exposure to such risks, there can be no  assurance
that  adverse  political changes  will  not cause  a Fund  to  suffer a  loss of
interest or principal on any of its holdings.
 
In recent years, some of the emerging market countries in which the Funds expect
to invest  have  encountered  difficulties in  servicing  their  sovereign  debt
obligations.  Some  of these  countries have  withheld  payments of  interest on
and/or principal  of  sovereign  debt.  These  difficulties  have  also  led  to
agreements to restructure external debt obligations -- in particular, commercial
bank  loans,  typically by  rescheduling  principal payments,  reducing interest
rates and extending new credits to  finance interest payments on existing  debt.
In  the  future, holders  of emerging  market sovereign  debt securities  may be
requested to participate in similar rescheduling of such debt. Certain  emerging
market  countries are among the largest  debtors to commercial banks and foreign
governments. Currently, Brazil,  Mexico and  Argentina are  the largest  debtors
among  developing  countries. At  times certain  emerging market  countries have
declared moratoria on the  payment of principal and  interest on external  debt;
such  a moratorium is currently in  effect in certain emerging market countries.
There is no bankruptcy proceeding by which a creditor may collect in whole or in
part sovereign debt on which an emerging market government has defaulted.
 
The ability of  emerging market  governments to  make timely  payments on  their
sovereign  debt is likely  to be influenced  strongly by a  country's balance of
trade and its access to trade  and other international credits. A country  whose
exports  are concentrated in a few commodities  could be vulnerable to a decline
in the  international prices  of  one or  more  of such  commodities.  Increased
protectionism  on the part of a  country's trading partners could also adversely
affect its  exports.  Such  events  could diminish  a  country's  trade  account
surplus,  if any. To the extent that  a country receives payment for its exports
in currencies other  than hard  currencies, its  ability to  make hard  currency
payments could be affected.
 
Investors  should also be aware that certain sovereign debt instruments in which
the Funds may invest involve great risk. Some of such securities with respect to
which the issuer  currently may  not be  paying interest  or may  be in  payment
default,  may be comparable to securities rated D by S&P or C by Moody's. A Fund
may have difficulty disposing of and valuing certain sovereign debt  obligations
because there may be a limited trading market for such securities. Because there
is no liquid secondary market for many of these securities, the Funds anticipate
that  such  securities could  be sold  only to  a limited  number of  dealers or
institutional investors.
 
    RISKS  OF   MORTGAGE-BACKED   AND   ASSET-BACKED   SECURITIES.   The   yield
characteristics of mortgage-backed and asset-backed securities differ from those
of  traditional  bonds.  Among  the  major  differences  are  that  interest and
principal payments are made more frequently (usually monthly) and that principal
may be prepaid at any time because the underlying mortgage loans or other assets
generally may  be prepaid  at  any time.  Generally, prepayments  on  fixed-rate
mortgage  loans  will increase  during a  period of  falling interest  rates and
decrease  during  a  period  of  rising  interest  rates.  Mortgage-backed   and
asset-backed  securities may also decrease in value  as a result of increases in
interest rates and, because  of prepayments, may benefit  less than other  bonds
from  declining interest rates. Reinvestments of  prepayments may occur at lower
interest rates than the original  investment, thus adversely affecting a  Fund's
yield.  Actual prepayment  experience may cause  the yield  of a mortgage-backed
security to differ from what was  assumed when the Fund purchased the  security.
The  market for privately issued  mortgage-backed and asset-backed securities is
smaller and  less liquid  than the  market for  U.S. government  mortgage-backed
securities.
 
CMO  classes may be specially structured in a manner that provides any of a wide
variety of investment  characteristics, such  as yield,  effective maturity  and
interest  rate sensitivity. As market conditions change, however, and especially
during periods of rapid or unanticipated  changes in market interest rates,  the
attractiveness  of some CMO classes and the  ability of the structure to provide
the anticipated investment characteristics  may be significantly reduced.  These
changes  can result  in volatility  in the market  value, and  in some instances
reduced liquidity, of the CMO class.
 
Certain classes of  CMOs are structured  in a manner  that makes them  extremely
sensitive   to   changes   in  prepayment   rates.   Interest-only   ("IO")  and
principal-only ("PO") classes are examples of this. IOs are entitled to  receive
all  or a portion  of the interest, but  none (or only a  nominal amount) of the
principal payments, from the underlying mortgage assets. If the mortgage  assets
underlying an IO experience greater than anticipated principal prepayments, then
the  total amount of interest payments allocable  to the IO class, and therefore
the yield  to  investors, generally  will  be  reduced. In  some  instances,  an
investor  in an IO may fail to recoup all of his or her initial investment, even
if the security is government guaranteed or  is considered to be of the  highest
credit  quality. Conversely, PO classes are entitled to receive all or a portion
of the  principal  payments, but  none  of  the interest,  from  the  underlying
mortgage assets. PO classes are purchased at substantial discounts from par, and
the  yield to investors  will be reduced  if principal payments  are slower than
expected. Some IOs and POs, as well as other CMO classes, are structured to have
special protections against the effects of
 
                  Statement of Additional Information Page 38

                      GT GLOBAL VARIABLE INVESTMENT FUNDS
prepayments. These structural protections, however, normally are effective  only
within certain ranges of prepayment rates and thus will not protect investors in
all circumstances.
 
Inverse  floating rate CMO classes also may be extremely volatile. These classes
pay interest at a  rate that decreases  when a specified  index of market  rates
increases.
 
During 1994, the value and liquidity of many mortgage-backed securities declined
sharply  due primarily to increases in interest rates. There can be no assurance
that such declines will not recur.  The market value of certain  mortgage-backed
securities,  including IO and  PO classes of  mortgage-backed securities, can be
extremely volatile and these securities may become illiquid.
 
Foreign mortgage-backed securities markets  are substantially smaller than  U.S.
markets,  but  have been  established in  several countries,  including Germany,
Denmark, Sweden, Canada, and Australia, and may be developed elsewhere.  Foreign
mortgage-backed   securities  generally  are   structured  similar  to  domestic
mortgage-backed securities,  and  they normally  present  substantially  similar
investment  risks as  well as the  other risks normally  associated with foreign
securities.

ALL FUNDS
 
For purposes of each Fund's concentration policy (except with respect to  Growth
&  Income Fund),  the Fund intends  to comply  with the SEC  staff position that
securities issued  or guaranteed  as to  principal and  interest by  any  single
foreign  government  or any  supranational  organizations in  the  aggregate are
considered to be securities of issuers in the same industry.
 
If a percentage restriction  is adhered to  at the time  of investment, a  later
increase  or decrease in percentage resulting from  a change in values or assets
will not constitute a violation of that restriction.
 
All of the Funds have the following investment policies, which may be changed by
the Company's Board of Trustees without shareholder or investor approval:
 
No Fund may:
 
        (1) Hold assets of any issuers, at  the end of any calendar quarter  (or
    within 30 days thereafter), to the extent such holdings would cause the Fund
    to fail to comply with the diversification requirements for segregated asset
    accounts  used to fund variable annuity  contracts imposed by Section 817(h)
    of the Code and the Treasury regulations issued thereunder; or
 
        (2) Except under  unusual circumstances, purchase  securities issued  by
    investment  companies  unless they  are issued  by  companies that  follow a
    policy of investment primarily  in the capital markets  of a single  foreign
    entity.
 
Policies  that are  designated as  operating policies  may be  changed only upon
approval  by  the  Board  of  Trustees  and  following  appropriate  notice   to
shareholders.

                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
Subject  to policies established by each Company's Board of Trustees, AIM and/or
the sub-advisors  are responsible  for the  execution of  the Funds'  securities
transactions  and the selection of  broker/dealers who execute such transactions
on behalf of the Funds. In  executing transactions, AIM and/or the  sub-advisors
seek the best net results for each Fund, taking into account such factors as the
price  (including the applicable brokerage commission or dealer spread), size of
the order,  difficulty  of execution  and  operational facilities  of  the  firm
involved.   While  AIM   and/or  the  sub-advisors   generally  seek  reasonably
competitive commission rates and  spreads, payment of  the lowest commission  or
spread  is not necessarily consistent with the best net results. While the Funds
may engage  in soft  dollar  arrangements for  research services,  as  described
below,  the Funds have no obligation to deal  with any broker or dealer or group
of brokers or dealers in the execution of securities transactions.
 
Consistent with the  interests of  the Funds,  AIM and/or  the sub-advisors  may
select  brokers on the basis of the research and brokerage services they provide
to AIM and/or the  sub-advisors for their  use in managing  the Funds and  their
other  advisory accounts. Such services may include furnishing analyses, reports
and information concerning issuers, industries,

securities, geographic regions, economic factors and trends, portfolio strategy,
and  performance  of  accounts;   and  effecting  securities  transactions   and
performing  functions  incidental thereto  (such  as clearance  and settlement).
Research and brokerage services received from  such brokers are in addition  to,
and  not in  lieu of, the  services required to  be performed by  AIM and/or the
sub-advisors  under  investment  management  and  administration  contracts.   A
commission  paid to such brokers may be higher than that which another qualified
broker would have charged for effecting the same transaction, provided that  AIM
and/or  the  sub-advisors  determine  in  good  faith  that  such  commission is
reasonable in  terms  either  of  that particular  transaction  or  the  overall
responsibility of AIM and/or the sub-advisors to the Funds and its other clients
and  that the total commissions paid by each Fund will be reasonable in relation
to the benefits received by the Funds over the long term. Research services  may
also be received from dealers who execute Fund transactions in OTC markets.
 
AIM   and/or   the   sub-advisors  may   allocate   brokerage   transactions  to
broker/dealers who have entered into arrangements under which the  broker/dealer
allocates  a portion of the commissions paid  by the Funds toward payment of the
Funds' expenses, such as custodian fees.
 
Investment decisions for each Fund and for other investment accounts managed  by
AIM  and/or the sub-advisors  are made independently  of each other  in light of
differing conditions. However, the same investment decision occasionally may  be
made  for two  or more of  such accounts, including  one or more  Funds. In such
cases simultaneous transactions may occur. Purchases or sales are then allocated
as to price  or amount in  a manner deemed  fair and equitable  to all  accounts
involved. While in some cases this practice could have a detrimental effect upon
the price or value of the security as far as a Fund is concerned, in other cases
AIM  and/or  the  sub-advisors  believe that  coordination  and  the  ability to
participate in volume transactions will be beneficial to the Funds.
 
Under a policy adopted by each Company's  Board of Trustees, and subject to  the
policy  of  obtaining the  best  net results,  AIM  and/or the  sub-advisors may
consider a broker/dealer's sale of the shares of the Funds, and the other  funds
for  which AIM and the sub-advisors serve as investment manager or administrator
in selecting brokers and dealers  for the execution of securities  transactions.
This  policy  does not  imply a  commitment  to execute  securities transactions
through all broker/ dealers that sell shares of such funds.
 
Each Fund contemplates purchasing most foreign equity securities in OTC  markets
or  stock exchanges located  in the countries in  which the respective principal
offices of the issuers of the various securities are located if that is the best
available market.  The  fixed commissions  paid  in connection  with  most  such
foreign  stock transactions generally are  higher than negotiated commissions on
U.S. transactions. There generally is less government supervision and regulation
of foreign  stock exchanges  and  brokers than  in  the United  States.  Foreign
security  settlements may  in some  instances be  subject to  delays and related
administrative uncertainties.
 
Foreign equity securities may be held by a Fund in the form of ADRs, ADSs, EDRs,
GDRs, CDRs or securities convertible into foreign equity securities. ADRs, ADSs,
EDRs, GDRs and  CDRs may  be listed  on stock exchanges,  or traded  in the  OTC
markets  in the United  States or Europe, as  the case may  be. ADRs, like other
securities traded in the United States, will be subject to negotiated commission
rates. The foreign and domestic debt securities and money market instruments  in
which the Funds may invest are generally traded in the OTC markets.
 
The Funds contemplate that, consistent with the policy of obtaining the best net
results,  brokerage transactions may be conducted  through affiliates of AIM and
the sub-advisors. Each  Company's Board  of Trustees has  adopted procedures  in
conformity  with Rule  17e-1 under  the 1940  Act to  ensure that  all brokerage
commissions paid to such  affiliates are reasonable and  fair in the context  of
the  market in which they are operating.  Any such transactions will be effected
and  related  compensation   paid  only  in   accordance  with  applicable   SEC
regulations.

TRADING AND TURNOVER
Although each Fund does  not intend generally to  trade for short-term  profits,
the securities held by that Fund will be sold whenever management believes it is
appropriate to do so, without regard to the length of time a particular security
may have been held. Portfolio turnover rate is calculated by dividing the lesser
of  sales or purchases of portfolio  securities by each Fund's average month-end
portfolio value, excluding short-term  investments. The portfolio turnover  rate
will note a limiting factor when management deems portfolio changes appropriate.
Higher portfolio turnover involves correspondingly greater brokerage commissions
and  other transaction costs that the Fund will bear directly, and may result in
the realization of net capital gains  that are taxable when distributed to  each
Fund's  shareholders. The portfolio turnover rates  for the Funds for the fiscal
year ended December 31, 1998 and 1997, were as follows:

The  Board of Trustees has  a Nominating and Audit  Committee, comprised of Miss
Quigley and Messrs.  Anderson, Bayley  and Patterson, which  is responsible  for
nominating  persons to serve as Trustees, reviewing  audits of the Trust and its
funds and recommending firms to serve as independent auditors of the Trust.  All
of  the Trust's Trustees also  serve as directors or trustees  of some or all of
the other investment companies managed, administered  or advised by AIM. All  of
the  Trust's executive  officers hold  similar offices with  some or  all of the
other investment companies managed, administered or advised by AIM. Each Trustee
who is not a director, officer or employee of [INVESCO (NY), Inc.] or any  other
affiliated  company is paid aggregate fees of  $5,000 a year, plus $300 per Fund
for each meeting of the Board attended, and reimbursed travel and other expenses
incurred in  connection with  attendance at  such meetings.  Other Trustees  and
officers  receive no compensation or expense reimbursement from the Trust. As of

EXPENSES OF THE FUNDS
As  described in  the Funds'  Prospectus, each Fund  pays all  of its respective
expenses not  assumed  by  other  parties. The  allocation  of  general  Company
expenses  and expenses shared by the Funds  with one another, are allocated on a
basis deemed fair and equitable, which may  be based on the relative net  assets
of  the Funds or the nature of the services performed and relative applicability
to each  Fund. Expenditures,  including costs  incurred in  connection with  the
purchase  or  sale  of  securities, which  are  capitalized  in  accordance with
generally accepted accounting principles applicable to investment companies, are
accounted for as capital  items and not  as expenses. The  ratio of each  Fund's
expenses  to  its relative  net assets  can be  expected to  be higher  than the
expense ratios of funds investing solely in domestic securities, since the  cost
of  maintaining the  custody of  foreign securities  and the  rate of investment
management fees  paid by  each Fund  generally are  higher than  the  comparable
expenses of such other funds.

                            VALUATION OF FUND SHARES
 
- --------------------------------------------------------------------------------
 
As  described in the Funds' Prospectus, each Fund's net asset value per share is
determined each day on which  the New York Stock  Exchange ("NYSE") is open  for
business  ("Business  Day") as  of  the close  of  regular trading  on  the NYSE
(currently 4:00 p.m. Eastern  Time, unless weather,  equipment failure or  other
factors contribute to an earlier closing time). Currently, the NYSE is closed on
weekends and on certain days relating to the following holidays: New Year's Day,
Martin Luther King Day, President's Day, Good Friday, Memorial Day, Independence
Day, Labor Day, Thanksgiving Day and Christmas Day.
 
The  portfolio securities and other assets of the Funds, other than those of the
Money Market Fund, are valued as follows:
 
Equity securities including ADRs, ADSs, GDRs and EDRs, which are traded on stock
exchanges, are valued  at the  last sale  price on  the exchange  on which  such
securities are traded, as of the close of business on the day the securities are
being  valued or, lacking any  sales, at the last  available bid price. In cases
where securities are traded on more than one exchange, the securities are valued
on the  exchange  determined  by  the Sub-advisor  to  be  the  primary  market.
Securities  traded in the OTC market are valued at the last available sale price
prior to the time of valuation.
 
Long-term debt obligations are valued at  the mean of representative quoted  bid
and  asked prices for such  securities or, if such  prices are not available, at
prices for securities of  comparable maturity, quality  and type; however,  when
the  Sub-advisor deems it appropriate, prices  obtained for the day of valuation
from a  bond pricing  service  will be  used.  Short-term debt  investments  are
amortized  to  maturity  based  on their  cost,  adjusted  for  foreign exchange
translation.
 
Options on indices, securities and currencies purchased by the Funds are  valued
at  their last bid  price in the  case of listed  options or in  the case of OTC
options, at the average of the last  bid prices obtained from dealers, unless  a
quotation  from only one dealer  is available, in which  case only that dealer's
price will be used.  When market quotations for  futures and options on  futures
held  by a Fund are readily available, those positions will be valued based upon
such quotations.
 
Securities and  other  assets  for  which  market  quotations  are  not  readily
available  (including restricted securities which  are subject to limitations as
to their sale) are valued at fair value as determined in good faith by or  under
the  direction  of  the  relevant Company's  Board  of  Trustees.  The valuation
procedures applied in  any specific  instance are likely  to vary  from case  to
case. However, consideration generally is given to the financial position of the
issuer  and other fundamental analytical data  relating to the investment and to
the nature of the restrictions on  disposition of the securities (including  any
registration  expenses that  might be  borne by a  Fund in  connection with such
disposition). In addition,  specific factors generally  are considered, such  as
the  cost of the investment, the market  value of any unrestricted securities of
the same class (both at the time of purchase and at the time of valuation),  the
size  of  the holding,  the prices  of  any recent  transactions or  offers with
respect to such  securities and  any available analysts'  reports regarding  the
issuer.
 
The  fair value  of any  other assets is  added to  the value  of all securities
positions to arrive at the value of a Fund's total assets. A Fund's liabilities,
including accruals for expenses,  are deducted from its  total assets. Once  the
total  value of a Fund's net assets is so determined, that value is then divided
by the total number of shares  outstanding (excluding treasury shares), and  the
result, rounded to the nearer cent, is the net asset value per share.
 
Any assets or liabilities initially expressed in terms of foreign currencies are
translated  into U.S. dollars at  the official exchange rate  or, at the mean of
the current bid and asked prices of such currencies against the U.S. dollar last
quoted by a major  bank that is  a regular participant  in the foreign  exchange
market  or on the basis of a pricing  service that takes into account the quotes
provided by a  number of such  major banks.  If none of  these alternatives  are
available  or none are deemed to provide a suitable methodology for converting a
foreign currency into U.S. dollars, the relevant Company's Board of Trustees, in
good faith, will establish a conversion rate for such currency.
 
Trading in foreign securities may not take  place on all days on which the  NYSE
is  open. Further, trading takes place in  various foreign markets on other days
on which the NYSE is not open. Trading in securities on European and Far Eastern
securities exchanges and OTC markets normally is completed well before the close
of regular trading  on the  NYSE. Consequently,  the calculation  of the  Funds'
respective  net  asset  values may  not  take place  contemporaneously  with the
determination of the prices of securities  held by the respective Funds.  Events
affecting the values of such securities that
 
                  Statement of Additional Information Page 61
<PAGE>
                      GT GLOBAL VARIABLE INVESTMENT FUNDS
occur  between the  time their  prices are determined  and the  close of regular
trading on the NYSE  will not be  reflected in the  respective Funds' net  asset
values  unless the Sub-advisor, under the  supervision of the relevant Company's
Board of Trustees, determines that the particular event would materially  affect
net  asset value.  As a result,  a Fund's  net asset value  may be significantly
affected by such trading  on days when a  shareholder cannot purchase or  redeem
shares of the Fund.
 
A  Fund may declare a suspension of  the determination of net asset value during
the periods when it may suspend redemption privileges.
 
The Board of Trustees of G.T.  Global Variable Investment Series has  determined
in  good faith that the net  asset value of each share  of the Money Market Fund
will remain constant at $1.00  and, although no assurance  can be given that  it
will  be able to  do so on  a continuing basis,  the Money Market  Fund will, as
described  below,  employ  specific   investment  policies  and  procedures   to
accomplish  this result. The  Money Market Fund  values its portfolio securities
using the amortized cost  method. The amortized cost  method involves valuing  a
security  at  its cost  and thereafter  accruing  any discount  or premium  at a
constant rate to maturity. Although this method provides certainty in valuation,
it may result  in periods  during which  the value  of the  Money Market  Fund's
securities,  as determined by amortized cost, is  higher or lower than the price
the Money Market Fund would receive if it sold the securities. During periods of
declining interest rates, the daily yield  on the Money Market Fund computed  as
described  above may tend to be higher than a like computation made by a similar
fund with  identical investments  utilizing  a method  of valuation  based  upon
market prices and estimates of market prices for all of its securities. Thus, if
the  Money Market  Fund's use  of amortized cost  resulted in  a lower aggregate
value on a particular day, a prospective investor in the Money Market Fund would
be able to obtain a somewhat higher yield than would result from investment in a
similar fund  utilizing solely  market values,  and existing  Money Market  Fund
shareholders would receive less investment income. The converse would apply in a
period of rising interest rates.
 
In  connection with  the Money  Market Fund's  policy of  valuing its securities
using the  amortized  cost  method,  the Fund  adheres  to  certain  conditions,
including  maintaining a dollar-weighted average maturity of 90 days or less and
purchasing only securities having remaining maturities of 13 months or less. The
Board of Trustees of G.T. Global Variable Investment Series also has established
procedures designed to stabilize, to  the extent reasonably possible, the  Money
Market Fund's net asset value per share at $1.00. Such procedures include review
of  securities holdings by  the Board of  Trustees, at such  intervals as it may
deem appropriate, to determine whether the  Money Market Fund's net asset  value
calculated  by using  available market  quotations deviates  from the  net asset
value calculated by  using the amortized  cost method and,  if so, whether  such
deviation may result in material dilution or may be otherwise unfair to existing
investors. In the event the Board of Trustees of G.T. Global Variable Investment
Series  determines that such  a deviation exists,  the Board has  agreed to take
such corrective action as it deems necessary and appropriate, which action might
include selling securities prior to maturity to realize capital gains or  losses
or  to shorten average maturity, withholding income, or establishing a net asset
value by using available market quotations or market equivalents.

Each Company  is a  funding vehicle  for VA  Contracts offered  by the  separate
accounts  of  the  Participating  Insurance  Companies.  Individual  VA Contract
holders are not the shareholders of a Fund. Rather, each Participating Insurance
Company and its separate accounts are the shareholders (the "shareholders"). The
offering is without a sales  charge and is made at  each Fund's net asset  value
per share, which is determined in the manner set forth above under "Valuation of
Shares."
 
Due  to differences in  tax treatment or other  considerations, the interests of
various VA Contract  holders might at  some time be  in conflict. The  Companies
currently  do not foresee  any such conflict. However,  the Companies' Boards of
Trustees intend  to  monitor  events to  identify  any  material  irreconcilable
conflict that may arise and to determine what action, if any, should be taken in
response  to  such conflict.  If  such a  conflict were  to  occur, one  or more
Participating Insurance  Companies'  Separate  Accounts  might  be  required  to
withdraw  all or a substantial portion of  its investments in one or more Funds.
This might  disrupt  a Fund's  orderly  portfolio management  to  the  potential
detriment of VA Contract holders.

arising from any activity which is primarily  intended to result in the sale  of
shares  issued by the  Companies), including expenses  and costs attributable to
the  Companies,  which  are  related   to  the  printing  and  distributing   of
prospectuses to prospective owners of the VA Contracts.
 
Each  Company redeems  all full and  fractional shares  of its Funds  at the net
asset value per share applicable to each of its Funds. See "Valuation of Shares"
above.
 
Payment upon redemption is made in  cash and ordinarily will occur within  seven
days  of receipt of a proper notice of redemption. The right to redeem shares or
to receive payment with respect to any redemption of shares of any Fund may only
be suspended: (1) for any period during which trading on the NYSE is  restricted
or  such Exchange is  closed, other than customary  weekend and holiday closing;
(2) for  any period  during  which an  emergency exists  as  a result  of  which
disposal  of securities or determination of the  net asset value of that Fund is
not reasonably practicable;  or (3) for  such other  periods as the  SEC may  by
order permit for the protection of shareholders of that Fund.

                                     TAXES
 
- --------------------------------------------------------------------------------
 
GENERAL
Shares  of the Funds are offered only  to Separate Accounts that fund certain VA
Contracts. See the  applicable VA Contract  prospectus for a  discussion of  the
special taxation of insurance companies with respect to such accounts and of the
VA Contract holders.
 
Each  Fund is treated as a separate corporation for federal income tax purposes.
To continue to qualify  for treatment as  a RIC under the  Code, each Fund  must
distribute  to  its shareholders  for  each taxable  year  at least  90%  of its
investment company  taxable  income  (consisting  generally  of  net  investment
income, net short-term capital gain, and net gains from certain foreign currency
transactions)("Distribution  Requirement")  and  must  meet  several  additional
requirements.  With  respect  to  each  Fund,  these  requirements  include  the
following:  (1)  the Fund  must derive  at least  90% of  its gross  income each
taxable year  from  dividends, interest,  payments  with respect  to  securities
loans,  and gains from  the sale or  other disposition of  securities or foreign
currencies, or other income (including  gains from options, Futures, or  Forward
Contracts)  derived with respect  to its business of  investing in securities or
those currencies ("Income Requirement"); (2) at the close of each quarter of the
Fund's taxable year,  at least  50% of  the value of  its total  assets must  be
represented  by cash and  cash items, U.S.  government securities, securities of
other RICs,  and  other securities,  with  these other  securities  limited,  in
respect  of any one issuer, to an amount that does not exceed 5% of the value of
the Fund's  total assets  and  that does  not represent  more  than 10%  of  the
issuer's  outstanding voting securities; and (3) at the close of each quarter of
the Fund's taxable year, not more than 25% of the value of its total assets  may
be  invested  in  securities  (other  than  U.S.  government  securities  or the
securities of other RICs) of any one  issuer. If any Fund failed to qualify  for
treatment  as a  RIC for any  taxable year, (1)  it would be  taxed at corporate
rates on the full amount of its taxable income for that year without being  able
to  deduct the distributions it makes  to its shareholders, (2) the shareholders
would treat all those distributions, including distributions of net capital gain
(I.E., the excess  of net  long-term capital  gain over  net short-term  capital
loss),  as dividends  (that is,  ordinary income)  to the  extent of  the Fund's
earnings and profits, and (3)  most importantly, each Separate Account  invested
therein would fail to satisfy the diversification requirements of section 817(h)
of  the Code  (see below), with  the result  that the VA  Contracts supported by
those accounts would no  longer be eligible for  tax deferral. In addition,  the
Fund  could be required to recognize unrealized gains, pay substantial taxes and
interest  and  make  substantial  distributions  before  requalifying  for   RIC
treatment.
 
As  noted in the Funds' Prospectus, each Fund intends to continue to comply with
the diversification requirements imposed by section  817(h) of the Code and  the
regulations  thereunder.  These  requirements,  which  are  in  addition  to the
diversification requirements mentioned above,  place certain limitations on  the
proportion  of  each  Fund's  assets  that  may  be  represented  by  any single
investment (which includes all securities of the same issuer). Specifically, the
regulations provide  in part  that, except  as permitted  by the  "safe  harbor"
described  below,  as of  the end  of each  calendar quarter  or within  30 days
thereafter, no more than 55%  of the total assets of  a Fund may be invested  in
the  securities of any one issuer. For  this purpose, all securities of the same
issuer  are   consolidated,  and   while  each   U.S.  government   agency   and
instrumentality is considered a separate issuer, a particular foreign government
and   its  agencies,  instrumentalities  and   political  subdivisions  are  all
considered to be  the same issuer.  Section 817(h) provides,  as a safe  harbor,
that  adequate  diversification  will  exist  for  a  separate  account  if  the
diversification requirements under Subchapter M  are satisfied and no more  than
55% of the value of the separate account's total assets are cash and cash items,
government  securities and securities of  other registered investment companies.
Failure of a  Fund to satisfy  the section 817(h)  requirements would result  in
treatment  of the VA Contract holders other  than as described in the applicable
VA Contracts prospectus.
 
Dividends and  other  distributions  declared  by a  Fund  in,  and  payable  to
shareholders  of record as of  a date in, October,  November, or December of any
year will  be  deemed  to have  been  paid  by  the Fund  and  received  by  the
shareholders  on December 31 of  that year if the  distributions are paid by the
Fund during the following January.
 
Dividends and interest received  by a Fund, and  gains realized thereby, may  be
subject to income, withholding, or other taxes imposed by foreign countries that
would  reduce the yield  and/or total return on  its securities. Tax conventions
between certain countries and  the United States may  reduce or eliminate  these
foreign  taxes,  however, and  many  foreign countries  do  not impose  taxes on
capital gains with respect to investments by foreign investors.
 
                  Statement of Additional Information Page 64

Each Fund (other  than the Money  Market Fund,  the America Fund,  and the  U.S.
Government  Income Fund) may invest in  the stock of "passive foreign investment
companies"  ("PFICs").  A  PFIC  is  a  foreign  corporation  --  other  than  a
"controlled  foreign corporation" (I.E., a foreign  corporation in which, on any
day during its  taxable year, more  than 50% of  the total voting  power of  all
voting stock therein or the total value of all stock therein is owned, directly,
indirectly  or constructively, by  "U.S. shareholders," defined  as U.S. persons
that individually own, directly, indirectly  or constructively, at least 10%  of
that voting power) as to which a Fund is a U.S. shareholder -- that, in general,
meets  either of the  following tests: (1) at  least 75% of  its gross income is
passive or (2) an average of at least 50% of its assets produce, or are held for
the production of, passive income. Under  certain circumstances, a Fund will  be
subject to federal income tax on a portion of any "excess distribution" received
on  the  stock  of  a  PFIC  or  of  any  gain  from  disposition  of  the stock
(collectively  "PFIC  income"),  plus  interest   thereon,  even  if  the   Fund
distributes  the  PFIC income  as a  taxable dividend  to its  shareholders. The
balance of the  PFIC income will  be included in  the Fund's investment  company
taxable  income and,  accordingly, will not  be taxable  to it to  the extent it
distributes that income to its shareholders.
 
If a  Fund invests  in a  PFIC and  elects to  treat the  PFIC as  a  "qualified
electing  fund"  ("QEF"),  then  in  lieu  of  the  foregoing  tax  and interest
obligation, the Fund would be  required to include in  income each year its  pro
rata share of the QEF's ordinary earnings and net capital gain which most likely
would   have  to  be  distributed  by  the  Fund  to  satisfy  the  distribution
requirements described above -- even if the Fund did not receive those  earnings
and  gain from  the QEF. In  most instances, it  will be very  difficult, if not
impossible, to make this election because of certain requirements thereof.
 
Each  Fund   may  elect   to  "mark   to  market"   its  stock   in  any   PFIC.
"Marking-to-market,"  in this context,  means including in  ordinary income each
taxable year the excess, if  any, of the fair market  value of the stock over  a
Fund's  adjusted  basis therein  as of  the end  of that  year. Pursuant  to the
election, a Fund  also would  be allowed to  deduct (as  ordinary, not  capital,
loss)  the excess,  if any, of  its adjusted basis  in PFIC stock  over the fair
market value thereof as of the taxable  year-end, but only to the extent of  any
net  mark-to-market gains with respect  to that stock included  in income by the
Fund for  prior taxable  years. A  Fund's adjusted  basis in  each PFIC's  stock
subject  to the  election would  be adjusted  to reflect  the amounts  of income
included and deductions taken thereunder (and under regulations proposed in 1992
that provided a similar election with respect to the stock of certain PFICs).
 
OPTIONS, FUTURES, AND FOREIGN CURRENCY TRANSACTIONS
A Fund's use of hedging transactions,  such as selling (writing) and  purchasing
options  and Futures and entering into Forward Contracts, involves complex rules
that will determine for federal income tax purposes, the amount, character,  and
timing  of recognition  of the  gains and losses  a Fund  realizes in connection
therewith. Gains  from the  disposition of  foreign currencies  (except  certain
gains  that  may be  excluded by  future regulations),  and gains  from options,
Futures, and Forward Contracts derived by a Fund with respect to its business of
investing in  securities  or foreign  currencies,  will qualify  as  permissible
income under the Income Requirement.
 
Futures  and Forward  Contracts that  are subject  to section  1256 of  the Code
(other than Forward  Contracts that are  part of a  "mixed straddle")  ("Section
1256  Contracts") and that  are held by  a Fund at  the end of  its taxable year
generally will be deemed to  have been sold at  market value for federal  income
tax  purposes. Sixty percent of any net  gain or loss recognized on these deemed
sales, and 60% of any net realized gain or loss from any actual sales of Section
1256 Contracts,  will be  treated as  long-term capital  gain or  loss, and  the
balance  will be  treated as  short-term capital gain  or loss.  These rules may
operate to  increase the  amount that  a  Fund must  distribute to  satisfy  the
Distribution  Requirement and to  increase the net capital  gain recognized by a
Fund, without in either case increasing the  cash available to the Fund. A  Fund
may  elect to exclude  certain transactions from the  operation of section 1256,
although doing so may have the  effect of increasing the relative proportion  of
net  short-term capital gain and/or increasing the amount of dividends that must
be distributed to meet the Distribution Requirement.
 
Section 988 of the Code also may apply to gains and losses from transactions  in
foreign  currencies, foreign currency-denominated  debt securities, and options,
Futures, and Forward  Contracts on  foreign currencies ("section  988 gains  and
losses").  Each section  988 gain or  loss generally is  computed separately and
treated as ordinary income or loss. In the case of overlap between sections 1256
and 988, special provisions  determine the character and  timing of any  income,
gain,  or  loss.  Each Fund  attempts  to  monitor section  988  transactions to
minimize any adverse tax impact.
 
If a Fund  has an  "appreciated financial  position" --  generally, an  interest
(including  an interest through an option, Futures or Forward Contract, or short
sale) with respect to any stock,  debt instrument (other than "straight  debt"),
or  partnership interest  the fair  market value  of which  exceeds its adjusted
basis -- and  enters into  a "constructive sale"  of the  same or  substantially
similar  property,  that Fund  will be  treated  as having  made an  actual sale
thereof, with  the  result  that  gain  will  be  recognized  at  that  time.  A
constructive  sale generally  consists of a  short sale,  an offsetting notional
principal contract, or Futures or Forward Contract  entered into by a Fund or  a
related   person   with   respect   to  the   same   or   substantially  similar
 
                  Statement of Additional Information Page 65

                      GT GLOBAL VARIABLE INVESTMENT FUNDS
property. In addition, if the appreciated  financial position is itself a  short
sale or such a contract, acquisition of the underlying property or substantially
similar  property will  be deemed  a constructive  sale. The  foregoing will not
apply, however,  to any  transaction of  a  Fund during  any taxable  year  that
otherwise  would be treated as a constructive  sale if the transaction is closed
within 30 days after  the end of  that year and the  Fund holds the  appreciated
financial  position unhedged for  60 days after  that closing (I.E.,  at no time
during that 60-day  period is the  Fund's risk of  loss regarding that  position
reduced   by  reason   of  certain   specified  transactions   with  respect  to
substantially similar or  related property, such  as having an  option to  sell,
being  contractually  obligated to  sell, making  a short  sale, or  granting an
option to buy substantially identical stock or securities).
 
The foregoing is a general and abbreviated summary of certain federal income tax
considerations affecting each  Fund. No attempt  is made to  present a  complete
explanation  of the  federal tax  treatment of  the Funds'  activities, and this
discussion  is  not  intended  as   a  substitute  for  careful  tax   planning.
Accordingly, potential investors are urged to consult their own tax advisors for
more  detailed information  and for information  regarding any  state, local, or
foreign taxes applicable to the Funds  and to dividends and other  distributions
therefrom.

conducts  an annual  audit of  the Fund's  Financial Statements,  assists in the
preparation of the Funds' federal and state income tax returns and consults with
the Companies and the Funds as to matters of accounting, regulatory filings, and
federal and state income taxation.
 
The audited financial statements of each Company and each Fund included in  this
Statement  of Additional Information have been examined by [      ] as stated in
its opinion appearing  herein, and are  included in reliance  upon such  opinion
given upon the authority of that firm as experts in accounting and auditing.
 
SHAREHOLDER LIABILITY
Under  Delaware law, the shareholders of each Company enjoy the same limitations
of liability extended to shareholders of private, for-profit corporations. There
is a remote possibility, however, that under certain circumstances  shareholders
of  each Company may  be held personally liable  for each Company's obligations.
However, each Company's Agreement and Declaration of Trust disclaims shareholder
liability for acts  or obligations of  the Company and  requires that notice  of
such  disclaimer be  given in each  agreement, obligation  or instrument entered
into or  executed by  the Company  or a  trustee. Each  Company's Agreement  and
Declaration  of Trust provides for indemnification from the Company property for
all losses  and expenses  of  any shareholder  held  personally liable  for  the
Company's  obligations. Thus, the risk of a shareholder incurring financial loss
on account of such liability is  limited to circumstances in which each  Company
itself  would be unable  to meet its  obligations and where  the other party was
held not to be bound by the disclaimer.

Each Fund's "Standardized Returns", as referred to in the Prospectus (see "Other
Information  -- Performance  Information" in  the Prospectus),  is calculated as
follows: Standardized Return  Standardized Return (average  annual total  return
("T")) is computed by using the ending redeeming value ("ERV") of a hypothetical
initial investment of $1,000 ("P") over a period of years ("n") according to the
following  formula as required by the SEC: P(1+T)  to the (n)th power = ERV. The
following assumptions will be reflected in computations made in accordance  with
this formula: (1) reinvestment of dividends and other distributions at net asset
value  on the reinvestment date determined  by the Companies' Board of Trustees;
and (2)  a  complete  redemption at  the  end  of any  period  illustrated.  The
Standardized  Return quotation  does not reflect  the charges  deducted from the
Participating Insurance  Companies'  separate  accounts.  See  the  VA  Contract
prospectus. If these charges were deducted to reflect the effective Standardized
Return  to the VA Contract  owner, that Standardized Return  would be lower than
the Standardized Returns quoted.

In  addition  to   Standardized  Returns,   each  Fund  also   may  include   in
advertisements,  sales  literature and  shareholder  reports other  total return
performance  data  ("Non-Standardized   Return").  Non-Standardized  Return   is
calculated  for a specified period of time  by assuming the investment of $1,000
in Fund shares and further assuming the reinvestment of all dividends and  other
distributions  made to Fund shareholders in  additional Fund shares at their net
asset value. Percentage rates  of return are then  calculated by comparing  this
assumed  initial investment to the value of  the hypothetical account at the end
of  the  period   for  which   the  Non-Standardized  Return   is  quoted.   The
Non-Standardized Return quotation does not reflect the charges deducted from the
Participating  Insurance  Companies'  separate  accounts.  See  the  VA Contract
prospectus.  If  these  charges  were  deducted,  the  Non-Standardized   Return
quotation  would be  lower than  those stated.  Non-Standardized Returns  may be
quoted for the same or different time periods for which Standardized Returns are
quoted.
 
Aggregate Non-Standardized Return ("T") is computed by using the ending value of
the account  ("VOA")  of  a  hypothetical initial  investment  of  $1,000  ("P")
according  to  the  following formula:  T=(VOA/P)-1.  Aggregate Non-Standardized
Return assumes reinvestment of dividends and other distributions.

The  Money Market  Fund may,  from time  to time,  provide yield  information or
comparisons of  its  yield  to  various  averages  including  data  from  Lipper
Analytical  Services,  Inc., Bank  Rate  Monitor-TM-, IBC/Donaghue's  Money Fund
Report, MONEY  Magazine, and  other industry  publications (to  the extent  they
apply  to investment  companies whose  shares are  offered to  insurance company
separate accounts,  in advertisements  or  in reports  furnished to  current  or
prospective shareholders).
 
The  Money Market Fund calculates its yield for its shares daily, based upon the
seven days ending on the day of  the calculation, called the "base period."  The
yield  is computed by determining the net  change in the value of a hypothetical
account with a balance of  one share at the beginning  of the base period,  with
the  net  change, excluding  capital  changes, but  including  the value  of any
additional shares purchased with  dividends earned from  the original one  share
and  all dividends declared  on the original and  any purchased shares; dividing
the net  change in  the account's  value  by the  value of  the account  at  the
beginning  of  the  base  period  to  determine  the  base  period  return;  and
multiplying the base period return by (365/7). The Money Market Fund's effective
yield is computed by compounding the unannualized base period return by adding 1
to the base period return; raising the sum to the 365/7th power; and subtracting
1 from the result.
 
For the seven-day period ended  December 31, 1998, the Fund's  yield was [    %]
and  effective  yield  was [     %].  See  "Management" in  the  Prospectus. The
seven-day and effective yields are calculated as follows:

Less beginning account value:......................................................  [$          ]

  Seven-day yield = $.000941213 X 365/7 = 4.91%
  Effective yield** = [1 + .000941213] 365/7 - 1 = 5.03%
</TABLE>
 
- ------------------
**  The effective yield assumes a year's compounding of the seven-day yield.
 
The  Money Market  Fund's investment results  may also be  calculated for longer
periods in accordance  with the  following method:  by subtracting  (a) the  net
asset  value of one share at the beginning of the period, from (b) the net asset
value of all shares an investor would own at the end of the period for the share
held at the beginning of the period (assuming reinvestment of all dividends  and
distributions)  and  dividing  by (c)  the  net  asset value  per  share  at the
beginning of  the period.  The resulting  percentage indicates  the positive  or
negative  rate of return that an investor  would have earned from the reinvested
dividends and distributions and  any changes in share  price during the  period.
These  performance  quotations  do not  reflect  the charges  deducted  from the
Participating Insurance  Companies'  separate  accounts.  See  the  VA  Contract
prospectus.  If these charges were deducted, such quotations would be lower than
those calculated for the Money Market Fund.
 
The performance  figures  for a  Fund  will  only be  advertised  if  comparable
performance  figures for the corresponding division  of the separate account are
included in the  advertisement. Each  Fund's investment results  will vary  from
time  to time  depending upon market  conditions, the composition  of the Fund's
portfolio and operating  expenses of the  Fund, so that  any performance  figure
should  not be considered representative  of what an investment  in the Fund may
earn in any future period. These factors and possible differences in calculation
methods should be considered when comparing the

Fund's investment results  with those published  for other investment  companies
and  other investment  vehicles whose  shares are  offered to  insurance company
separate accounts. Investment results also should be considered relative to  the
risks associated with the investment objective and policies.
 
IMPORTANT POINTS TO NOTE ABOUT THE FOLLOWING WORLD FINANCIAL AND ECONOMIC DATA
Information   relating  to   foreign  market   performance,  capitalization  and
diversification is based on  sources believed to be  reliable, but which may  be
subject  to revision  and which  has not  been independently  verified by either
Company or AIM Distributors. The authors and publishers of such material are not
to be considered as "experts"  under the Securities Act  of 1933, on account  of
the inclusion of such information herein.
 
AIM  Distributors  believes that  this information  may  be useful  to investors
considering whether and to  what extent to  diversify their investments  through
the purchase of mutual funds investing in securities on a global basis. However,
this data is not a representation of the past performance of any of these Funds,
nor  is it a prediction  of such performance. The  performance of the Funds will
differ from the historical performance of the relevant indices. The  performance
of  indices does not take expenses into account, while each Fund incurs expenses
in its operations, which will reduce performance. Each Fund is actively managed,
i.e., AIM  and/or the  sub-advisors, as  each Fund's  investment advisor  and/or
sub-advisor,  actively  purchase  and  sell securities  in  seeking  each Fund's
investment objective. Moreover, each Fund may invest a portion of its assets  in
corporate  bonds, while the above data relates only to government bonds. Each of
these factors will cause the performance of each Fund to differ from the indices
shown above.
 
Each Fund and AIM Distributors may  from time to time, in advertisements,  sales
literature and reports furnished to present or prospective shareholders, compare
the  Funds  with  the following,  among  others,  to the  extent  they  apply to
investment companies  whose shares  are offered  to insurance  company  separate
accounts:
 
        (1)  The Consumer Price Index ("CPI"), which is a measure of the average
    change in prices over time  in a fixed market  basket of goods and  services
    (E.G.,  food, clothing,  shelter, fuels,  transportation fares,  charges for
    doctors' and dentists' services, prescription medicines, and other goods and
    services that people  buy for  day-to-day living). There  is inflation  risk
    which does not affect a security's value but its purchasing power, I.E., the
    risk of changing price levels in the economy that affects security prices or
    the price of goods and services.
 
        (2)  Data,  mutual fund  rankings and  comparisons and  variable account
    rankings and comparisons  published or  prepared by  Lipper Analytical  Data

    ("CDA/Wiesenberger"), Morningstar,  Inc.  ("Morningstar"),  Micropal,  Inc.,
    Financial  Planning  Resources  Inc.,  publisher of  a  compilation  of data
    regarding variable  accounts  ("VARDS")  and/or other  companies  that  rank
    and/or compare mutual funds or variable annuity account divisions by overall
    performance,  investment  objectives,  assets,  expense  levels,  periods of
    existence and/or other factors. In this regard, each Fund may be compared to
    its "peer group" as defined by Lipper, CDA/Wiesenberger, Morningstar,  VARDS
    and/or  other firms, as applicable  or to specific funds  or groups of funds
    within or outside of  such peer group. Lipper  generally ranks funds on  the
    basis  of total return, assuming reinvestment of distributions, but does not
    take sales charges or  redemption fees into  consideration, and is  prepared
    without regard to tax consequences. In addition to the mutual fund rankings,
    the  Fund's performance may  be compared to  mutual fund performance indices
    prepared by Lipper. Morningstar  is a mutual fund  rating service that  also
    rates  mutual funds on  the basis of  risk-adjusted performance. Morningstar
    ratings are calculated from a fund's three, five and ten year average annual
    returns with appropriate  fee adjustments  and a risk  factor that  reflects
    fund  performance  relative to  the three-month  U.S. Treasury  bill monthly
    returns. Ten percent  of the funds  in an investment  category receive  five
    stars  and 22.5% receive four stars. The  ratings are subject to change each
    month.

       (22)  Average of  savings accounts,  which is a  measure of  all kinds of
    savings deposits, including longer-term certificates. Savings accounts offer
    a guaranteed rate  of return on  principal, but no  opportunity for  capital

    by law.
 
To the extent that they apply  to investment companies whose shares are  offered
to  insurance company  separate accounts,  indices, economic  and financial data
prepared by the research departments of various financial organizations, such as
Salomon Brothers, Inc., Lehman Brothers, Merrill Lynch, Pierce, Fenner &  Smith,
Inc.,  Financial Research Corporation, J.P. Morgan, Morgan Stanley, Smith Barney
Shearson,  S.G.   Warburg,  Jardine   Flemming,  The   Bank  for   International
Settlements,  Asian Development  Bank, Bloomberg, L.P.,  and Ibbotson Associates
may be used  as well  as information  reported by  the Federal  Reserve and  the
respective  Central Banks of various nations.  In addition, AIM Distributors may
use performance  rankings,  ratings  and  commentary  reported  periodically  in
national financial publications, including MONEY MAGAZINE, MUTUAL FUND MAGAZINE,
SMART  MONEY,  GLOBAL  FINANCE,  EUROMONEY,  FINANCIAL  WORLD,  FORBES, FORTUNE,
BUSINESS WEEK, LATIN FINANCE, THE WALL STREET JOURNAL, EMERGING MARKETS  WEEKLY,
KIPLINGER'S GUIDE TO PERSONAL FINANCE, BARRON'S, THE FINANCIAL TIMES, USA TODAY,
THE  NEW YORK  TIMES and  INVESTORS BUSINESS DIGEST.  Each Fund  may compare its
performance to that of  other compilations or indices  of comparable quality  to
those listed above and other indices that may be developed and made available in
the future.
 
A  portion of the performance  figures for each market  includes the positive or
negative effects of the currency exchange rates effective at December 31 of each
year between the U.S. dollar and currency of the foreign market (E.G.,  Japanese
Yen,  German Deutschemark  and Hong  Kong Dollar).  A foreign  currency that has
strengthened or weakened against the  U.S. dollar will positively or  negatively
affect the reported returns, as the case may be.
 
AIM  Distributors  believes that  this information  may  be useful  to investors
considering whether and to  what extent to  diversify their investments  through
the purchase of mutual funds investing in securities on a global basis. However,

data  is not a representation of the past  performance of the Funds, nor is it a
prediction of such performance. The performance of the Fund will differ from the
historical performance of relevant indices. The performance of indices does  not
take  expenses into account,  while the Fund incurs  expenses in its operations,
which will reduce performance. Each of these factors will cause the  performance
of the Fund to differ from relevant indices.
 
From  time to time,  each Fund and AIM  Distributors may refer  to the number of
shareholders in the Fund  or the aggregate number  shareholders in all Funds  or
the dollar amount Fund assets under management in advertising materials.
 
AIM  Distributors believes  the GT  Global Variable  Investment Funds  can be an
appropriate  investment  for  long-term  investment  goals,  including   funding
retirement,  paying for  education or purchasing  a house.  AIM Distributors may
provide information  designed to  help individuals  understand their  investment
goals  and  explore various  financial strategies.  For  example, GT  Global may
describe  general   principles  of   investing,   such  as   asset   allocation,
diversification  and risk tolerance. The GT  Global Variable Investment Funds do
not represent a complete  investment program and  the investors should  consider
the  Funds as  appropriate for a  portion of their  overall investment portfolio
with regard to their long-term investment goals. There is no assurance that  any
such information will lead to achieving these goals or guarantee future results.
 
From  time to time, AIM Distributors may refer to or advertise the names of U.S.
and non-U.S. companies and  their products, although there  can be no  assurance
that  any GT  Global Variable  Investment Fund may  own the  securities of these
companies.
 
Advertising and  sales literature  for the  Contract may  discuss the  financial
ratings  of  any  of  the  Participating  Insurance  Companies  as  compiled  by
independent agencies.  These  independent  agencies  rate  insurance  companies'
overall  financial strength, ability to meet contractual obligations, ability to
discharge senior  policyholder  obligations and  claims,  overall  claims-paying
ability   and  other  financial  measures  related  to  long-term  solvency  and
liquidity. The independent  agencies which may  be quoted include,  but are  not
limited to:
 
    / / A.M. Best Company
 
    / / Moody's Investors Service
 
    / / Standard & Poor's Insurance Rating Services
 
    / / Duff & Phelps, Incorporated
 
Ratings descriptions are relevant only to the insurance company and do not apply
to  variable annuities  or the underlying  accounts which are  subject to market
risk and whose value will fluctuate with market conditions.
 
In addition, advertising and sales literature for the Contracts may discuss  the
assets of any of the Participating Insurance Companies, including a breakdown of
annuity  assets under management, as well as the number of years the company has
been involved in the annuity marketplace.
 
Ibbotson Associates of Chicago, Illinois (Ibbotson) provides historical  returns
of  the capital  markets in  the United  States, including  common stocks, small
capitalization stocks, long-term  corporate bonds, intermediate-term  government
bonds,  long-term government bonds,  Treasury bills, the  U.S. rate of inflation
(based on the CPI), and combinations of various capital markets. The performance
of these capital markets is based on the returns of different indices.
 
GT Global Variable  Investment Funds may  use the performance  of these  capital
markets in order to demonstrate general risk-versus-reward investment scenarios.
Performance  comparisons may also include the value of a hypothetical investment
in any of these capital markets. The risks associated with the security types in
any capital market may  or may not  correspond directly to  those of the  Funds.
Ibbotson calculates total returns in the same method as the Funds.
 
Each  Fund may quote  various measures of  volatility and benchmark correlation,
such as beta,  standard deviation and  R(2), in advertising.  In addition,  each
Fund  may compare these measures to those of other funds. Measures of volatility
seek to compare the Funds' historical  share price fluctuations or total  return
compared to those of a benchmark. All measures of volatility and correlation are
calculated using averages of historical data.
 
Each  Fund may  advertise examples of  the effect of  periodic investment plans,
including the principle of dollar cost averaging programs. In such a program, an
investor invests a fixed dollar amount in a Fund at periodic intervals,  thereby
purchasing  fewer shares when  prices are high  and more shares  when prices are
low. While such a strategy does not assure  a profit or guard against loss in  a
declining  market, the investor's  average cost per  share can be  lower than if
fixed numbers of shares are purchased at the same intervals. In evaluating  such
a  plan, investors should  consider their ability  to continue purchasing shares
through periods of low price levels.

Each Fund may describe in its sales material and advertisements how an  investor
may  invest in the Fund through various  retirement plans or other programs that
offer deferral of income taxes on  investment earnings and pursuant to which  an
investor  may make deductible contributions.  Because of their advantages, these
retirement plans  and  programs  may  produce  returns  superior  to  comparable
non-retirement  investments. For example, a $10,000 investment earning a taxable
return of 10% annually would have an after-tax value of $17,976 after ten years,
assuming tax  was  deducted from  the  return each  year  at a  39.6%  rate.  An
equivalent  tax-deferred  investment would  have an  after-tax value  of $19,626
after ten years, assuming  tax was deducted  at a 39.6%  rate from the  deferred
earnings   at  the   end  of  the   ten-year  period.  In   sales  material  and
advertisements, the Fund may also discuss these plans and programs.
 
AIM Distributors may  from time  to time in  its sales  methods and  advertising
discuss  the risks inherent in investing. The major types of investment risk are
market risk, industry risk, credit risk, interest rate risk, liquidity risk  and
inflation risk. Risk represents the possibility that you may lose some or all of
your investment over a period of time. A basic tenet of investing is the greater
the potential reward, the greater the risk.
 
From  time to time, the GT Global Variable Investment Funds and AIM Distributors
will quote  information  regarding industries,  individual  countries,  regions,
world  stock exchanges, and economic and demographic statistics from sources AIM

In addition, the GT  Global Variable Strategic Income  Fund, from time to  time,
may  quote  yields and  total returns  of  representative debt  instruments from
emerging market countries in its advertising and sales literature.
 
The Sub-advisor believes that  before emerging market  countries with high  debt
levels  can attract substantial amounts of  foreign capital, they must put their
financial houses in  order. Some emerging  markets governments have  implemented
debt  restructuring programs. From  time to time,  each Fund may  include in its
advertising and sales  material information on  emerging market countries'  debt
restructuring activities.
 
In  advertising and sales  materials, AIM Distributors may  make reference to or
discuss its products, services and accomplishments. Among these  accomplishments
are that in 1983 INVESCO (NY) provided assistance to the government of Hong Kong
in linking its currency to the U.S. dollar, and that in 1987 Japan's Ministry of
Finance  licensed  GT  Asset  Management  Ltd.  as  one  of  the  first  foreign
discretionary investment managers for Japanese investors. Such  accomplishments,
however,  should  not  be  viewed  as an  endorsement  of  INVESCO  (NY)  by the
government of Hong Kong, Japan's Ministry of Finance or any other government  or
government  agency. Nor do any such  accomplishments of INVESCO (NY) provide any
assurance that the  GT Global Variable  Investment Funds' investment  objectives
will be achieved.
 
ECONOMIC DEVELOPMENT IN EMERGING MARKETS
AIM  and/or the sub-advisors have identified six phases to track the progress of
developing economies.
 
In addition, AIM and/or the sub-advisors  focus on the transitions between  each
phase:
 
    BETWEEN  PHASES 1 & 2, STABILIZATION:  Developing nations recognize the need
for economic reform and launch initiatives to stabilize their economies. Typical
measures  might  include  initiating  monetary  reforms  to  contain  inflation,
controlling government spending, and addressing external trade imbalances.
 
    BETWEEN  PHASES 2 & 3, RENOVATION:  Economic development gathers momentum as
the  governments  of   developing  nations  take   further  steps  to   increase
productivity and external competitiveness. Typical reforms include easing market
regulations,  privatizing  state-owned industries,  lowering trade  barriers and
reforming the national tax structure.
 
    BETWEEN PHASES  3 &  4, NEW  CONSTRUCTION: As  economic reforms  take  hold,
infrastructure  improvements  are  needed to  facilitate  and  support long-term
growth. The construction and upgrading of highways and airports,  communications
and  utility systems  generally require  financing in  the form  of public debt.
Similarly, as  the private  sector develops,  bolstered by  new  privatizations,
corporate debt securities typically are issued to finance business expansion.
 
EMERGING MARKET TRADING VOLUME
The annual trading volume of debt securities from developing economies according
to  Salomon Brothers, Inc. has grown from $90 billion in 1990 to $150 billion in
1991 to $400 billion in 1992 and was  estimated to be $1,200 billion at the  end
of 1993 and $1.5 trillion at the end of 1994, respectively.

                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
    MOODY'S INVESTORS SERVICE, INC. ("Moody's") rates the debt securities issued
by  various entities from "Aaa"  to "C." Investment grade  ratings are the first
four categories:
 
        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  risk appear  somewhat
    larger than the 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
    some time in the future.
 
        Baa  --  Bonds  which  are  rated  Baa  are  considered  as medium-grade
    obligations, (i.e., they are neither  highly protected nor poorly  secured).
    Interest payments and principal security appear adequate for the present but
    certain  protective  elements may  be lacking  or may  be characteristically
    unreliable over  any  great length  of  time. Such  bonds  lack  outstanding
    investment  characteristics and in fact  have speculative characteristics as
    well.
 
        Ba -- Bonds which are rated Ba are judged to have speculative  elements;
    their  future cannot be considered as  well-assured. Often the protection of
    interest and principal payments may be  very moderate, and thereby not  well
    safeguarded  during both good and bad  times over the future. Uncertainty of
    position characterizes bonds in this class.
 
        B --  Bonds which  are rated  B generally  lack characteristics  of  the
    desirable  investment. Assurance  of interest  and principal  payments or of
    maintenance of other terms of the contract over any long period of time  may
    be small.
 
        Caa  -- Bonds which are rated Caa  are of poor standing. Such issues may
    be in default or  there may be  present elements of  danger with respect  to
    principal or interest.
 
        Ca  --  Bonds  which  are  rated  Ca  represent  obligations  which  are
    speculative in a high degree. Such issues are often in default or have other
    marked shortcomings.
 
        C -- Bonds which are  rated C are the lowest  rated class of bonds,  and
    issues  so rated can be regarded as  having extremely poor prospects of ever
    attaining any real investment standing.
 
ABSENCE OF RATING: 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 issue  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  judgement to  be formed; if  a bond is
called for redemption; or for other reasons.
 
Note: Moody's applies  numerical modifiers, 1,  2 and 3  in each generic  rating
classification  from Aa to Caa. The modifier  1 indicates that the Company ranks
in the higher end  of its generic  rating category; the  modifier 2 indicates  a
mid-range  ranking; and the modifier  3 indicates that the  Company ranks in the
lower end of its generic rating category.

                      GT GLOBAL VARIABLE INVESTMENT FUNDS
 
    STANDARD & POOR'S, a  division of The  McGraw-Hill Companies, Inc.  ("S&P"),
rates  the securities debt of various  entities in categories ranging from "AAA"
to "D"  according  to quality.  Investment  grade  ratings are  the  first  four
categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA   --  An  obligation  rated  "AA"  differs  from  the  highest  rated
    obligations only  in a  small degree.  The obligor's  capacity to  meet  its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB   --  An   obligation  rated  "BBB"   exhibits  adequate  protection
    parameters. However, adverse economic  conditions or changing  circumstances
    are  more likely to lead  to a weakened capacity of  the obligor to meet its
    financial commitment on the obligation.
 
        BB, B, CCC, CC, C -- Obligations  rated "BB," "B," "CCC," "CC," and  "C"
    are   regarded  as  having  significant  speculative  characteristics.  "BB"
    indicates the least degree  of speculation and "C"  the highest. While  such
    obligations  will likely  have some quality  and protective characteristics,
    these may be outweighed by large uncertainties or major exposures to adverse
    conditions.
 
        BB -- An  obligation rated "BB"  is less vulnerable  to nonpayment  than
    other  speculative issues. However, it  faces major ongoing uncertainties or
    exposure to adverse business, financial, or economic conditions which  could
    lead  to the obligor's inadequate capacity  to meet its financial commitment
    on the obligation.
 
        B --  An obligation  rated "B"  is more  vulnerable to  nonpayment  than
    obligations  rated "BB," but the obligor  currently has the capacity to meet
    its financial commitment on the obligation. Adverse business, financial,  or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC  -- An obligation rated "CCC" is currently vulnerable to nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for the obligor to meet its  financial commitment on the obligation. In  the
    event of adverse business, financial, or economic conditions, the obligor is
    not  likely to  have the  capacity to meet  its financial  commitment on the
    obligation.
 
        CC --  An  obligation  rated  "CC" is  currently  highly  vulnerable  to
    nonpayment.
 
        C  -- The "C" rating may be used to cover a situation where a bankruptcy
    petition has been filed  or similar action has  been taken, but payments  on
    this obligation are being continued.
 
        D  -- An  obligation rated  "D" is  in payment  default. The  "D" rating
    category is used when payments on an obligation are not made on the date due
    even if the  applicable grace period  has not expired,  unless S&P  believes
    that  such payments will  be made during  such grace period.  The "D" rating
    also will be used upon the filing of a bankruptcy petition or the taking  of
    a similar action if payments on an obligation are jeopardized.
 
PLUS  (+) OR MINUS  (-): The ratings from  "AA" to "CCC" may  be modified by the
addition of a  plus or minus  sign to  show relative standing  within the  major
rating categories.
 
NR:  Indicates that  no rating  has been  requested, that  there is insufficient
information on which to base  a rating, or that S&P  does not rate a  particular
type of obligation as a matter of policy.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S  employs  the  designation "Prime-1"  to  indicate  commercial paper
having 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 structure with
moderate reliance on debt and ample asset protection; broad margins in  earnings
coverage  of  fixed financial  charges and  high  internal cash  generation; and
well-established access to a range of  financial markets and assured sources  of
alternate liquidity. Issues rated Prime-2 have a strong ability for repayment of
senior  short-term debt obligations. This normally  will be evidenced by many of
the characteristics cited  above but  to a  lesser degree.  Earnings trends  and
coverage  ratios, while sound, may be  more subject to variation. Capitalization
characteristics, while  still  appropriate, may  be  more affected  by  external
conditions. Ample alternate liquidity is maintained.
 
    S&P  ratings of commercial paper are  graded into several categories ranging
from "A1" for the highest quality obligations  to "D" for the lowest. Issues  in
the  "A"  category are  delineated  with numbers  1, 2,  and  3 to  indicate the
relative degree  of safety.  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 will be denoted with a plus sign
(+) designation.  A-2  -- Capacity  for  timely  payments on  issues  with  this
designation  is satisfactory; however,  the relative degree of  safety is not as
high as for issues designated "A-1."

DEREGULATION IN THE UNITED STATES
The  United States  has been  the bellwether  for deregulation  of the telephone
industry. The  divestiture  of  the  Bell System  from  American  Telephone  and
Telegraph  has produced new competing companies  in the United States. Such U.S.
market-driven competition has,  for example,  led to lower  costs for  consumers
which in turn led to greater consumer usage and to higher industrywide revenues.
AIM  and/or the  sub-advisors expect this  scenario to continue  to benefit such

                      GT GLOBAL VARIABLE INVESTMENT TRUST,
                           A DELAWARE BUSINESS TRUST

                 Capitalized terms not specifically defined herein
              shall have the meanings ascribed to them in the Trust's
                 Agreement and Declaration of Trust ("Agreement").


                                  ARTICLE I

                                  OFFICES
     
     Section 1.  REGISTERED OFFICE. The registered office of GT Global 
Variable Investment Trust (the "Trust") shall be in the County of New Castle, 
State of Delaware.

     Section 2.  OTHER OFFICES. The Trust may also have offices at such other 
places both within and without the State of Delaware as the Trustees may from 
time to time determine or the business of the Trust may require.
     
                                 ARTICLE II

                                  TRUSTEES

     Section 1. NUMBER. The number of Trustees shall initially be five, and 
thereafter shall be such number as shall be fixed from time to time by 
resolution of the Board of Trustees; provided, however, that the number of 
Trustees shall in no event be less than two nor more than twelve.

     Section 2. TERM. The Trustees shall hold office during the lifetime of 
the Trust, except (a) that any Trustee may resign his trusteeship or may 
retire by written instrument signed by him and delivered to the other 
Trustees, which shall take effect upon such delivery or upon such later date 
as is specified therein; (b) that any Trustee may be removed at any time by 
written instrument, signed by at least two-thirds of the number of Trustees 
prior to such removal, specifying the date when such removal shall become 
effective; (c) that any Trustee who has died, become physically or mentally 
incapacitated by reason of disease or otherwise, or is otherwise unable to 
serve, may be retired by written instrument signed by a majority of the other 
Trustees, specifying the date of his retirement; and (d) that a Trustee may 
be removed at any meeting of the shareholders of the Trust.

     Section 3. VACANCY. In case of the declination to serve, death, 
resignation, retirement or removal of a Trustee, or a Trustee is otherwise 
unable to serve, or an increase in the number of Trustees, a vacancy shall 
occur. Whenever a vacancy in the Trustees shall occur, until such vacancy is 
filled, the other Trustees shall have all the powers hereunder and the 
certification of

                                       1

<PAGE>

the other Trustees of such vacancy shall be conclusive. In the case of an 
existing vacancy, the remaining Trustees may fill such vacancy by appointing 
such other person as they in their discretion shall see fit, or may leave 
such vacancy unfilled or may reduce the number of Trustees to not less than 
two Trustees. Such appointment shall be evidenced by a written instrument 
signed by a majority of the Trustees in office or by resolution of the 
Trustees, duly adopted, which shall be recorded in the minutes of a meeting 
of the Trustees, whereupon the appointment shall take effect.

     An appointment of a Trustee may be made by the Trustees then in office 
in anticipation of a vacancy to occur by reason of retirement, resignation or 
increase in number of Trustees effective at a later date, provided that said 
appointment shall become effective only at or after the effective date of 
said retirement, resignation or increase in number of Trustees. As soon as 
any Trustee appointed pursuant to Sections 2 and 3 of Article II of these 
Amended and Restated Bylaws, or elected pursuant to Section 3 of Article IV, 
and the Agreement shall have accepted this appointment in writing and agreed 
in writing to be bound by the terms of the Trust Agreement, the Trust estate 
shall vest in the new Trustee or Trustees, together with the continuing 
Trustees, without any further act or conveyance, and he shall be deemed a 
Trustee hereunder.

     Section 4. DELEGATION OF POWER. Any Trustee may, by power of attorney, 
delegate his power for a period not exceeding six months at any one time to 
any other Trustee or Trustees, provided that in no case shall less than two 
Trustees personally exercise the other powers hereunder except as herein 
otherwise expressly provided.

     Section 5. INABILITY TO SERVE FULL TERM. The declination to serve, 
death, resignation, retirement, removal, incapacity, or inability of the 
Trustees, or any one of them, shall not operate to terminate the Trust or to 
revoke any existing agency created pursuant to the terms of the Agreement.

     Section 6. POWERS. The Trustees shall have exclusive and absolute 
control over the trust property and over the business of the Trust to the 
same extent as if the Trustees were the sole owners of the trust property and 
business in their own right, but with such powers of delegation as may be 
permitted by the Agreement. The Trustees shall have power to conduct the 
business of the Trust and carry on its operations in any and all of its 
branches and maintain offices both within and without the State of Delaware, 
in any and all states of the United States of America, in the District of 
Columbia, in any and all commonwealths, territories, dependencies, colonies, 
or possessions of the United States of America, and in any foreign 
jurisdiction and to do all such other things and execute all such instruments 
as they deem necessary, proper or desirable in order to promote the interests 
of the Trust although such things are not herein specifically mentioned. Any 
determination as to what is in the interests of the Trust made by the 
Trustees in good faith shall be conclusive. In construing the provisions of 
these Amended and Restated Bylaws and the Agreement, the presumption shall be 
in favor of a grant of power to the Trustees.

     Section 7. MEETINGS OF THE TRUSTEES. The Trustees of the Trust may 
hold meetings, both regular and special, either within or without the State 
of Delaware.

                                      2

<PAGE>

     Section 8. REGULAR MEETINGS. Regular meetings of the Board of 
Trustees shall be held each year, at such time and place as the Board of 
Trustees may determine.

     Section 9. NOTICE OF MEETINGS. Notice of the time, date, and place 
of all meetings of the Trustees shall be given to each Trustee by telephone, 
facsimile, electronic-mail, or other electronic mechanism sent to his or her 
home or business address at least twenty-four hours in advance of the meeting 
or in person at another meeting of the Trustees or by written notice mailed 
to his or her home or business address at least seventy-two hours in advance 
of the meeting.

     Section 10. QUORUM. At all meetings of the Trustees, a majority of 
the Trustees then in office (but in no event less than two Trustees) shall 
constitute a quorum for the transaction of business and the act of a majority 
of the Trustees present at any meeting at which there is a quorum shall be 
the act of the Board of Trustees, except as may be otherwise specifically 
provided by applicable law or by the Agreement or these Amended and Restated 
Bylaws. If a quorum shall not be present at any meeting of the Board of 
Trustees, the Trustees present thereat may adjourn the meeting from time to 
time, without notice other than announcement at the meeting, until a quorum 
shall be present.

     Section 11. ACTION WITHOUT MEETING. Unless otherwise restricted by 
the Agreement or these Amended and Restated Bylaws, any action required or 
permitted to be taken at any meeting of the Board of Trustees or of any 
committee thereof may be taken without a meeting by unanimous written consent 
of the Trustees or committee members (or by written consent of a majority of 
the Trustees if the President of the Trust determines that such exceptional 
circumstances exist, and are of such urgency, as to make unanimous written 
consent impossible or impractical, which determination shall be conclusive 
and binding on all Trustees and not otherwise subject to challenge) and the 
writing or writings are filed with the minutes of proceedings of the board or 
committee.

     Section 12. DESIGNATION, POWERS, AND NAME OF COMMITTEES. The Board 
of Trustees may, by resolution passed by a majority of the whole Board, 
designate one or more committees, each committee to consist of two or more of 
the Trustees of the Trust. The Board may designate one or more Trustee as 
alternate members of any committee, who may replace any absent or 
disqualified member at any meeting of such committee. Each committee, to the 
extent provided in the resolution, shall have and may exercise the powers of 
the Board of Trustees in the management of the business and affairs of the 
Trust; provided, however, that in the absence or disqualification of any 
member of such committee or committees, the member or members thereof present 
at any meeting and not disqualified from voting, whether or not such members 
constitute a quorum, may unanimously appoint another member of the Board of 
Trustees to act at the meeting in the place of any such absent or 
disqualified member. Such committee or committees shall have such name or 
names as may be determined from time to time by resolution adopted by the 
Board of Trustees.

     Section 13. MINUTES OF COMMITTEE. Each committee shall keep 
regular minutes of its meetings and report the same to the Board of Trustees 
when required.

     Section 14. COMPENSATION OF TRUSTEES. The Trustees as such shall be 
entitled to reasonable compensation for their services as determined from 
time to time by the Board of Trustees. Nothing herein shall in any way 
prevent the employment of any Trustee for advisory, management, 
administrative, legal, accounting, investment banking, underwriting, 
brokerage, or investment dealer or other services and the payment for the 
same by the Trust.

                               ARTICLE III

                                OFFICERS

     Section 1.  EXECUTIVE OFFICERS. The initial executive officers of the 
Trust shall be elected by the Board of Trustees as soon as practicable after 
the organization of the Trust. The executive officers may include a Chairman 
of the Board, and shall include a President, one or more Vice Presidents (the 
number thereof to be determined by the Board of Trustees), a Secretary and a 
Treasurer. The Chairman of the Board, if any, shall be selected from among 
the Trustees. The Board of Trustees may also in its discretion appoint 
Assistant Vice Presidents, Assistant Secretaries, Assistant Treasurers, and 
other officers, agents and employees, who shall have such authority and 
perform such duties as the Board may determine. The Board of Trustees may 
fill any vacancy which may occur in any office. Any two offices, except for 
those of President and Vice President, may be held by the same person, but no 
officer shall execute, acknowledge or verify any instrument on behalf of the 
Trust in more than one capacity, if such instrument is required by law or by 
these Amended and Restated Bylaws to be executed, acknowledged or verified by 
two or more officers.

     Section 2.  TERM OF OFFICE. Unless otherwise specifically determined by 
the Board of Trustees, the officers shall serve at the pleasure of the Board 
of Trustees. If the Board of Trustees in its judgment finds that the best 
interests of the Trust will be served, the Board of Trustees may remove any 
officer of the Trust at any time with or without cause.  The Trustees may 
delegate this power to the President with respect to any other officer.  Such 
removal shall be without prejudice to the contract rights, if any, of the 
person so removed.  Any officer may resign from office at any time by 
delivering a written resignation to the Trustees or the President.  Unless 
otherwise specified therein, such resignation shall take effect upon delivery.

     Section 3.  PRESIDENT. The President shall be the chief executive 
officer of the Trust and, subject to the Board of Trustees, shall generally 
manage the business and affairs of the Trust. If there is no Chairman of the 
Board, or if the Chairman of the Board has been appointed but is absent, the 
President shall, if present, preside at all meetings of the shareholders and 
the Board of Trustees.

     Section 4. CHAIRMAN OF THE BOARD. The Chairman of the Board, if any, 
shall preside at all meetings of the shareholders and the Board of Trustees, 
if the Chairman of the Board is present. The Chairman of the Board shall have 
such other powers and duties as shall be determined by the Board of Trustees, 
and shall undertake such other assignments as may be requested by the 
President.

                                      4

<PAGE>

     Section 5. OTHER OFFICERS. The Chairman of the Board or one or 
more Vice Presidents shall have and exercise such powers and duties of the 
President in the absence or inability to act of the President, as may be 
assigned to them, respectively, by the Board of Trustees or, to the extent 
not so assigned, by the President.  In the absence or inability to act of the 
President, the powers and duties of the President not otherwise assigned by 
the Board of Trustees or the President shall devolve upon the Chairman of the 
Board, or in the Chairman's absence, the Vice Presidents in the order of 
their election.

     Section 6. SECRETARY. The Secretary shall (a) have custody of the seal 
of the Trust; (b) attend meetings of the shareholders, the Board of Trustees, 
and any committees of Trustees and keep the minutes of such meetings of 
shareholders, Board of Trustees and any committees thereof; and (c) issue all 
notices of the Trust. The Secretary shall have charge of the shareholder 
records and such other books and papers as the Board may direct, and shall 
perform such other duties as may be incidental to the office or which are 
assigned by the Board of Trustees. The Secretary shall also keep or cause to 
be kept a shareholder book, which may be maintained by means of computer 
systems, containing the names, alphabetically arranged, of all persons who 
are shareholders of the Trust, showing their places of residence, the number 
and class or series of any class of shares of beneficial interest held by 
them, respectively, and the dates when they became the record owners thereof, 
and such book shall be open for inspection as prescribed by the laws of the 
State of Delaware.

     Section 7. TREASURER. The Treasurer shall have the care and custody of 
the funds and securities of the Trust and shall deposit the same in the name 
of the Trust in such bank or banks or other depositories, subject to 
withdrawal in such manner as these Amended and Restated Bylaws or the Board 
of Trustees may determine. The Treasurer shall, if required by the Board of 
Trustees, give such bond for the faithful discharge of duties in such form as 
the Board of Trustees may require.

     Section 8. SURETY BOND. The Trustees may require any officer or agent of 
the Trust to execute a bond (including, without limitation, any bond required 
by the Investment Company Act of 1940, as amended ("1940 Act") and the rules 
and regulations of the Securities and Exchange Commission ("Commission") to 
the Trust in such sum and with such surety or sureties as the Trustees may 
determine, conditioned upon the faithful performance of his or her duties to 
the Trust, including responsibility for negligence and for the accounting of 
any of the Trust's property, funds, or securities that may come into his or 
her hands.
     
                                    ARTICLE IV

                             MEETINGS OF SHAREHOLDERS

     Section 1. PURPOSE. All meetings of the shareholders for the election of 
Trustees shall be held at such place as may be fixed from time to time by the 
Trustees, or at such other place either within or without the State of 
Delaware as shall be designated from time to time by the Trustees and stated 
in the notice indicating that a meeting has been called for such purpose. 
Meetings of shareholders may be held for any purpose determined by the 
Trustees and may be held at such

                                      5

<PAGE>

time and place, within or without the State of Delaware as shall be stated in 
the notice of the meeting or in a duly executed waiver of notice thereof. At 
all meetings of the shareholders, every shareholder of record entitled to 
vote thereat shall be entitled to vote either in person or by proxy, which 
term shall include proxies provided through written, electronic, telephonic, 
computerized, facsimile, telecommunications, telex or oral communication or 
by any other form of communication, each pursuant to such voting procedures 
and through such systems as are authorized by the Trustees or one or more 
executive officers of the Trust. Unless a proxy provides otherwise, such 
proxy is not valid more than eleven months after its date. A proxy with 
respect to shares held in the name of two or more persons shall be valid if 
executed by any one of them unless at or prior to exercise of the proxy the 
Trust receives a specific written notice to the contrary from any one of 
them. A proxy purporting to be executed by or on behalf of a shareholder 
shall be deemed valid unless challenged at or prior to its exercise and the 
burden of proving invalidity shall rest on the challenger.

     Section 2.  NOMINATIONS OF TRUSTEES. Nominations of individuals for 
election to the board of trustees shall be made by the Board of Trustees or a 
nominating committee of the Board of Trustees, if one has been established 
(the "Nominating Committee"). Any shareholder of the Trust may submit names 
of individuals to be considered by the Nominating Committee or the Board of 
Trustees, as applicable, provided, however, (i) that such person was a 
shareholder of record at the time of submission of such names and is entitled 
to vote at the meeting, and (ii) that the Nominating Committee or the Board 
of Trustees, as applicable, shall make the final determination of persons to 
be nominated.

     Section 3. ELECTION OF TRUSTEES. All meetings of shareholders for 
the purpose of electing Trustees shall be held on such date and at such time 
as shall be designated from time to time by the Trustees and stated in the 
notice of the meeting, at which the shareholders shall elect by a plurality 
vote any number of Trustees as the notice for such meeting shall state are to 
be elected, and transact such other business as may properly be brought 
before the meeting in accordance with Section 1 of this Article IV.

     Section 4. NOTICE OF MEETINGS. Written notice of any meeting stating the 
place, date, and hour of the meeting shall be given to each shareholder 
entitled to vote at such meeting not less than ten days before the date of 
the meeting in accordance with Article V hereof.

     Section 5. SPECIAL MEETINGS. Special meetings of the shareholders, for 
any purpose or purposes, unless otherwise prescribed by applicable law or by 
the Agreement, may be called by any Trustee; provided, however, that the 
Trustees shall promptly call a meeting of the shareholders solely for the 
purpose of removing one or more Trustees, when requested in writing so to do 
by the record holders of not less than ten percent of the outstanding shares 
of the Trust.

     Section 6. NOTICE OF SPECIAL MEETING. Written notice of a special 
meeting stating the place, date, and hour of the meeting and the purpose of 
purposes for which the meeting is called, shall be given not less than ten 
days before the date of the meeting, to each shareholder entitled to vote at 
such meeting.

     Section 7. CONDUCT OF SPECIAL MEETING. Business transacted at any 
special meeting of shareholders shall be limited to the purpose stated in the 
notice.

     Section 8. QUORUM. The holders of one-third of the shares of beneficial 
interests that are issued and outstanding and entitled to vote thereat, 
present in person or represented by proxy, shall constitute a quorum at all 
meetings of the shareholders for the transaction of business except as 
otherwise provided by applicable law or by the Agreement.  If, however, such 
quorum shall not be present or represented at any meeting of the 
shareholders, the vote of the holders of a majority of shares cast shall have 
power to adjourn the meeting from time to time, without notice other than 
announcement at the meeting, until a quorum shall be present or represented.  
At such adjourned meeting, at which a quorum shall be present or represented,

meeting as originally notified.
     

     Section 9. ORGANIZATION OF MEETINGS.

            (a)  The Chairman of the Board of Trustees shall preside at each 
meeting of shareholders. In the absence of the Chairman of the Board, the 
meeting shall be chaired by the President, or if the President shall not be 
present, by a Vice President. In the absence of all such officers, the 
meeting shall be chaired by a person elected for such purpose at the meeting. 
The Secretary of the Trust, if present, shall act as Secretary of such 
meetings, or if the Secretary is not present, an Assistant Secretary of the 
Trust shall so act, and if no Assistant Secretary is present, then a person 
designated by the Secretary of the Trust shall so act, and if the Secretary 
has not designated a person, then the meeting shall elect a secretary for the 
meeting.

            (b)  The Board of Trustees of the Trust shall be entitled to make 
such rules and regulations for the conduct of meetings of shareholders as it 
shall deem necessary, appropriate or convenient. Subject to such rules and 
regulations of the Board of Trustees, if any, the chairman of the meeting 
shall have the right and authority to prescribe such rules, regulations and 
procedures and to do all such acts as, in the judgment of such chairman, are 
necessary, appropriate or convenient for the proper conduct of the meeting, 
including, without limitation, establishing: an agenda or order of business 
for the meeting; rules and procedures for maintaining order at the meeting 
and the safety of those present; limitations on participation in such meeting 
to shareholders of record of the Trust and their duly authorized and 
constituted proxies, and such other persons as the chairman shall permit; 
restrictions on entry to the meeting after the time fixed for the 
commencement thereof; limitations on the time allotted to questions or 
comments by participants; and regulation of the opening and closing of the 
polls for balloting on matters which are to be voted on by ballot, unless and 
to the extent the Board of Trustees or the chairman of the meeting determines 
that meetings of shareholders shall not be required to be held in accordance 
with the rules of parliamentary procedure.

     Section 10. VOTING STANDARD. When a quorum is present at any meeting, 
the vote of the holders of a majority of the shares cast shall decide any 
question brought before such meeting, unless the question is one on which, by 
express provision of applicable law, the Agreement, these Amended and 
Restated Bylaws, or applicable contract, a different vote is required, in 
which case such express provision shall govern and control the decision of 
such question.

     Section 11. VOTING PROCEDURE. Each whole share shall be entitled to one 
vote, and each fractional share shall be entitled to a proportionate 
fractional vote. On any matter submitted to a vote of the shareholders, all 
shares shall be voted together, except when required by applicable law or 
when the Trustees have determined that the matter affects the interests of 
one or more Portfolios (or Classes), then only the shareholders of such 
Portfolios (or Classes) shall be entitled to vote thereon.

     Section 12. ACTION WITHOUT MEETING. Unless otherwise provided in the 
Agreement or applicable law, any action required to be taken at any meeting 
of shareholders of the Trust, or any action which may be taken at any meeting 
of such shareholders, may be taken without a meeting, without prior notice 
and without a vote, if a consent in writing, setting forth the action so 
taken, shall be signed by the holders of outstanding shares having not less 
than the minimum number of votes that would be necessary to authorize or take 
such action at a meeting at which all shares entitled to vote thereon were 
present and voted. Prompt notice of the taking of any such action without a 
meeting by less than unanimous written consent shall be given to those 
shareholders who have not consented in writing.

                                     NOTICES

     Section 1. METHODS OF GIVING NOTICE. Whenever, under the provisions of 
applicable law or of the Agreement or of these Amended and Restated Bylaws, 
notice is required to be given to any Trustee or shareholder, it shall not, 
unless otherwise provided herein, be construed to mean personal notice, but 
such notice may be given orally in person, or by telephone (promptly 
confirmed in writing) or in writing, by mail addressed to such Trustee or 
shareholder, at his address as it appears on the records of the Trust, with 
postage thereon prepaid, and such notice shall be deemed to be given at the 
time when the same shall be deposited in the United States mail. Notice to 
Trustees or members of a committee may also be given by telex, telegram, 
telecopier or via overnight courier.  If sent by telex or telecopier, notice 
to a Trustee or member of a committee shall be deemed to be given upon 
transmittal; if sent by telegram, notice to a Trustee or member of a 
committee shall be deemed to be given when the telegram, so addressed, is 
delivered to the telegraph company, and if sent via overnight courier, notice 
to a Trustee or member of a committee shall be deemed to be given when 
delivered against a receipt therefor.

     Section 2. WRITTEN WAIVER. Whenever any notice is required to be given 
under the provisions of applicable law or of the Agreement or of these 
Amended and Restated Bylaws, a waiver thereof in writing, signed by the 
person or persons entitled to said notice, whether before or after the time 
stated therein, shall be deemed equivalent thereto.

                                 ARTICLE VI

                           CERTIFICATES OF SHARES

     Section 1. ISSUANCE. Upon request, every holder of shares in the 
Trust shall be entitled to have a certificate, signed by, or in the name of 
the Trust by, a Trustee, certifying the number of shares owned by him in the 
Trust.

     Section 2. COUNTERSIGNATURE. Where a certificate is countersigned (1) by 
a transfer agent other than the Trust or its employee, or, (2) by a registrar 
other than the Trust or its employee, the signature of the Trustee may be a 
facsimile.

     Section 3. LOST CERTIFICATES. The Board of Trustees may direct a new 
certificate or certificates to be issued in place of any certificate or 
certificates therefore issued by the Trust alleged to have been lost, stolen 
or destroyed, upon the making of an affidavit of the fact by the person 
claiming the certificate to be lost, stolen or destroyed. When authorizing 
such issue of a new certificate or certificates, the Board of Trustees may, 
in its discretion and as a condition precedent to the issuance thereof, 
require the owner of such lost, stolen or destroyed certificate or 
certificates, or his legal representative, to advertise the same in such 
manner as it shall require and/or to give the Trust a bond in such sum as it 
may direct as indemnity against any claim that may be made against the Trust 
with respect to the certificate alleged to have been lost, stolen or 
destroyed.

     Section 4. TRANSFER OF SHARES. The Trustees shall make such rules as 
they consider appropriate for the transfer of shares and similar matters. To 
the extent certificates are issued in accordance with Section 1 of this 
Article VI, upon surrender to the Trust or the transfer agent of the Trust of 
such certificate for shares duly endorsed or accompanied by proper evidence 
of succession, assignment or authority to transfer, it shall be the duty of 
the Trust to issue a new certificate to the person entitled thereto, cancel 
the old certificate and record the transaction upon its books.

     Section 5. FIXING RECORD DATE. In order that the Trustees may determine 
the shareholders entitled to notice of or to vote at any meeting of 
shareholders or any adjournment thereof, or to express consent to action in 
writing without a meeting, or entitled to receive payment of any dividend or 
other distribution of allotment of any rights, or entitled to exercise any 
rights in respect of any change, conversion or exchange of beneficial 
interests or for the purpose of any other lawful action, the Board of 
Trustees may fix a record date, which record date shall not precede the date 
upon which the resolution fixing the record date is adopted by the Board of 
Trustees, and which record date shall not be more than ninety nor less than 
ten days before the date of such meeting, nor more than ten days after the 
date upon which the resolution fixing the record date is adopted by the Board 
of Trustees for action by shareholder consent in writing without a meeting, 
nor more than ninety days prior to any other action. A determination of 
shareholders of record entitled to notice of or to vote at a meeting of 
shareholders shall apply to any adjournment of the meeting; provided, 
however, that the Board of Trustees may fix a new record date for the 
adjourned meeting.

                                      9

     Section 6. REGISTERED SHAREHOLDERS. The Trust shall be entitled to 
recognize the exclusive right of a person registered on its books as the 
owner of shares to receive dividends, and to vote as such owner, and to hold 
liable for calls and assessments a person registered on its books as the 
owner of shares, and shall not be bound to recognize any equitable or other 
claim to interest in such share or shares on the part of any other person, 
whether or not it shall have express or other notice hereof, except as 
otherwise provided by the laws of Delaware.



                                 ARTICLE VII

                             GENERAL PROVISIONS

     Section 1. DIVIDENDS AND OTHER DISTRIBUTIONS. The Trustees may from time 
to time declare and pay dividends and make other distributions with respect 
to any Portfolio, or Class thereof, which may be from income, capital gains 
or capital.  The amount of such dividends or other distributions and the 
payment of them and whether they are in cash or any other Trust Property 
shall be wholly in the discretion of the Trustees.

    Section 2. REDEMPTIONS. Any holder of record of shares of a particular 
Portfolio, or Class thereof, shall have the right to require the Trust to 
redeem his shares, or any portion thereof, subject to the terms and 
conditions set forth in the registration statement in effect from time to 
time.  The redemption price may in any case or cases be paid wholly or partly 
in kind if the Trustees determine that such payment is advisable in the 
interest of the remaining shareholders of the Portfolio or Class thereof for 
which the shares are being redeemed. Subject to the foregoing, the fair 
value, selection and quantity of securities or other property so paid or 
delivered as all or part of the redemption price may be determined by or 
under authority of the Trustees. In no case shall the Trust be liable for any 
delay of any Person in transferring securities selected for delivery as all 
or part of any payment in kind.
     
     The Trustees may, at their option, and at any time, have the right to 
redeem shares of any shareholder of a particular Portfolio or Class thereof 
in accordance with Section 2 of this Article VII. The Trustees may refuse to 
transfer or issue shares to any person to the extent that the same is 
necessary to comply with applicable law or advisable to further the purposes 
for which the Trust is formed.

     If, at any time when a request for transfer or redemption of Shares of 
any Portfolio is received by the Trust or its agent, the value of the shares 
of such Portfolio in a Shareholder's account is less than Five Hundred 
Dollars ($500.00), after giving effect to such transfer or redemption, the 
Trust may, at any time following such transfer or redemption and upon giving 
thirty (30) days' notice to the Shareholder, cause the remaining Shares of 
such Portfolio in such Shareholder's account to be redeemed at net asset 
value in accordance with such procedures set forth above.

      Section 3. INDEMNIFICATION. Every person who is, or has been, a Trustee 
or officer of the Trust shall be indemnified by the Trust to the fullest 
extent permitted by the Delaware Business Trust Act, these Amended and 
Restated Bylaws and other applicable law.

                                      10

<PAGE>

      Section 4. ADVANCE PAYMENTS OF INDEMNIFIABLE EXPENSES. To the maximum 
extent permitted by the Delaware Act and other applicable law, the Trust or 
applicable Portfolio may advance to a Covered Person, in connection with the 
preparation and presentation of a defense to any claim, action, suit, or 
proceeding, expenses for which the Covered Person would ultimately be 
entitled to indemnification; provided that the Trust or applicable Portfolio 
has received an undertaking by or on behalf of such Covered Person that such 
amount will be paid over by him to the Trust or applicable Portfolio if it is 
ultimately determined that he is not entitled to indemnification for such 
expenses, and further provided that (i) such Covered Person shall have 
provided appropriate security for such undertaking, (ii) the Trust is insured 
against losses arising out of any such advance payments, or (iii) either a 
majority of the Trustees who are not interested persons (as defined in the 
1940 Act) of the Trust nor parties to the matter, or independent legal 
counsel in a written opinion shall have determined, based upon a review of 
readily available facts (as opposed to a full trial-type inquiry) that there 
is reason to believe that such Covered Person will not be disqualified from 
indemnification for such expenses.

     Section 5. SEAL. The business seal shall have inscribed thereon the name 
of the business trust, the year of its organization and the word "Business 
Seal, Delaware."  The seal may be used by causing it or a facsimile thereof 
to be impressed or affixed or otherwise reproduced.  Any officer or Trustee 
of the Trust shall have authority to affix the corporate seal of the Trust to 
any document requiring the same.

     Section 6. SEVERABILITY. The provisions of these Amended and Restated 
Bylaws are severable.  If the Board of Trustees determines, with the advice 
of counsel, that any provision hereof conflicts with the 1940 Act, the 
regulated investment company provisions of the Internal Revenue Code, or 
other applicable laws and regulations, the conflicting provision shall be 
deemed never to have constituted a part of these Amended and Restated Bylaws; 
provided, however, that such determination shall not affect any of the 
remaining provisions of these Amended and Restated Bylaws or render invalid 
or improper any action taken or omitted prior to such determination.  If any 
provision hereof shall be held invalid or unenforceable in any jurisdiction, 
such invalidity or unenforceability shall attach only to such provision only 
in such jurisdiction and shall not affect any other provision of these 
Amended and Restated Bylaws.

     Section 7. HEADINGS. Headings are placed in these Amended and Restated 
Bylaws for convenience of reference only and in case of any conflict, the 
text of these Amended and Restated Bylaws rather than the headings shall 
control.

                                  ARTICLE VIII
                                   AMENDMENTS

    Section 1. AMENDMENTS. These Amended and Restated Bylaws may be altered 
or repealed at any regular or special meeting of the Board of Trustees 
without prior notice. These Amended and Restated Bylaws may also be altered 
or repealed at any special meeting of the shareholders, but only if the Board 
of Trustees resolves to put a proposed alteration or repealer to

                                      11

<PAGE>

the vote of the shareholders and notice of such alteration or repealer is 
contained in a notice of the special meeting being held for such purpose.

                       GT GLOBAL VARIABLE INVESTMENT TRUST
                               SUB-ADVISORY CONTRACT
                                      BETWEEN
                                A I M ADVISORS, INC.
                                        AND
                          INVESCO ASSET MANAGEMENT LIMITED

     Contract made as of December 14, 1998, between A I M Advisors, Inc., a 
Delaware corporation ("Adviser"), and INVESCO Asset Management Limited, a 
company organized under the laws of England and Wales ("Sub-Adviser"). 

     WHEREAS Adviser has entered into an Investment Management and 
Administration Contract with GT Global Variable Investment Trust ("Company"), 
an openend management investment company registered under the Investment 
Company Act of 1940, as amended ("1940 Act"), with respect to GT Global 
Variable Latin America Fund, GT Global Variable Growth & Income Fund, GT 
Global Variable Emerging Markets Fund and GT Global Variable Global 
Government Income Fund, each Fund being a series of the Company's shares of 
beneficial interest; and 

     WHEREAS Adviser desires to retain Sub-Adviser as sub-adviser to furnish 
certain advisory services to the Funds, and Sub-Adviser is willing to furnish 
such services; 

     NOW THEREFORE, in consideration of the promises and the mutual covenants 
herein contained, it is agreed between the parties hereto as follows: 

 1.  APPOINTMENT.  Adviser hereby appoints Sub-Adviser as sub-adviser of each 
Fund for the period and on the terms set forth in this Contract. Sub-Adviser 
accepts such appointment and agrees to render the services herein set forth, 
for the compensation herein provided. 

 2.  DUTIES AS SUB-ADVISER.  

     (a)  Subject to the supervision of the Company's Board of Trustees 
("Board") and Adviser, the Sub-Adviser will provide a continuous investment 
program for each Fund, including investment research and management, with 
respect to all securities and investments and cash equivalents of the Fund. 
The Sub-Adviser will determine from time to time what securities and other 
investments will be purchased, retained or sold with respect to each Fund, 
and the brokers and dealers through whom trades will be executed. 

     (b)  The Sub-Adviser agrees that, in placing orders with brokers, it will 
attempt to obtain the best net result in terms of price and execution. 
Consistent with this obligation, the Sub-Adviser may, in its discretion, 
purchase and sell portfolio securities from and to brokers and dealers who 
sell shares of the Funds or provide the Funds, Adviser's other clients, or 
Sub-Adviser's other clients with research, analysis, advice and similar 
services. The Sub-Adviser may pay to brokers and dealers, in return for such 
research and analysis, a higher commission or spread than may be charged by 
other brokers and dealers, subject to 

                                  1

<PAGE>

the Sub-Adviser's determining in good faith that such commission or spread is 
reasonable in terms either of the particular transaction or of the overall 
responsibility of the Adviser and Sub-Adviser to the Funds and their other 
clients and that the total commissions or spreads paid by each Fund will be 
reasonable in relation to the benefits to the Fund over the long term. In no 
instance will portfolio securities be purchased from or sold to the 
Sub-Adviser, or any affiliated person thereof, except in accordance with the 
federal securities laws and the rules and regulations thereunder and any 
exemptive orders currently in effect. Whenever the Sub-Adviser simultaneously 
places orders to purchase or sell the same security on behalf of a Fund and 
one or more other accounts advised by the Sub-Adviser, such orders will be 
allocated as to price and amount among all such accounts in a manner believed 
to be equitable to each account. The Company recognizes that in some cases 
this procedure may adversely affect the results attained for each Fund. 

     (c)  The Sub-Adviser will maintain all books and records with respect to 
the securities transactions of the Funds, and will furnish the Board and 
Adviser with such periodic and special reports as the Board or Adviser 
reasonably may request. In compliance with the requirements of Rule 31a-3 
under the 1940 Act, the Sub-Adviser hereby agrees that all records which it 
maintains for the Company are the property of the Company, agrees to preserve 
for the periods prescribed by Rule 31a-2 under the 1940 Act any records which 
it maintains for the Company and which are required to be maintained by 
Rule 31a-1 under the 1940 Act, and further agrees to surrender promptly to the 
Company any records which it maintains for the Company upon request by the 
Company. 

 3.  FURTHER DUTIES.  In all matters relating to the performance of this 
Contract, Sub-Adviser will act in conformity with the Agreement and 
Declaration of Trust, By-Laws and Registration Statement of the Company and 
with the instructions and directions of the Board and will comply with the 
requirements of the 1940 Act, the rules thereunder, and all other applicable 
federal and state laws and regulations. 

 4.  SERVICES NOT EXCLUSIVE.  The services furnished by Sub-Adviser hereunder 
are not to be deemed exclusive and Sub-Adviser shall be free to furnish 
similar services to others so long as its services under this Contract are 
not impaired thereby. Nothing in this Contract shall limit or restrict the 
right of any director, officer or employee of Sub-Adviser, who may also be a 
Trustee, officer or employee of the Company, to engage in any other business 
or to devote his or her time and attention in part to the management or other 
aspects of any other business, whether of a similar nature or a dissimilar 
nature. 

 5.  EXPENSES.  

     (a)  During the term of this Contract, each Fund will bear all expenses, 
not specifically assumed by Sub-Adviser, incurred in its operations and the 
offering of its shares. 

     (b)  Expenses borne by each Fund will include but not be limited to the 
following: (i) all direct charges relating to the purchase and sale of 
portfolio securities, 

                                  2

purchased or sold by the Fund and any losses incurred in connection 
therewith; (ii) fees payable to and expenses incurred on behalf of the Fund 
by Adviser under this Contract; (iii) investment consulting fees and related 
costs; (iv) expenses of organizing the Company and the Fund; (v) expenses of 
preparing and filing reports and other documents with governmental and 
regulatory agencies; (vi) filing fees and expenses relating to the

federal and/or state securities laws and maintaining such registrations and 
qualifications; (vii) costs incurred in connection with the issuance, sale, 
or repurchase of the Fund's shares of beneficial interest; (viii) fees and 
salaries payable to the Company's Trustees who are not parties to this 
Contract or interested persons of any such party ("Independent Trustees"); 
(ix) all expenses incurred in connection with the Independent Trustees' 
services, including travel expenses; (x) taxes (including any income or 
franchise taxes) and governmental fees; (xi) costs of any liability, 
uncollectible items of deposit and other insurance and fidelity bonds; (xii) 
any costs, expenses or losses arising out of a liability of or claim for 
damages or other relief asserted against the Company or the Fund for 
violation of any law; (xiii) interest charges; (xiv) legal, accounting and 
auditing expenses, including legal fees of special counsel for the 
Independent Trustees; (xv) charges of custodians, transfer agents, pricing 
agents and other agents; (xvi) expenses of disbursing dividends and 
distributions; (xvii) costs of preparing share certificates; (xviii) expenses 
of setting in type, printing and mailing prospectuses and supplements 
thereto, statements of additional information and supplements theeto, reports 
and proxy materials for existing shareholders; (xix) any extraordinary 
expenses (including fees and disbursements of counsel, costs of actions, 
suits or proceedings to which the Company is a party and the expenses the 
Company may incur as a result of its legal obligation to provide 
indemnification to its officers, Trustees, employees and agents) incurred by 
the Company or the Fund; (xx) fees, voluntary assessments and other expenses 
incurred in connection with membership in investment company organizations; 
(xxi) costs of mailing and tabulating proxies and costs of meetings of 
shareholders, the Board and any committees thereof; (xxii) the cost of 
investment company literature and other publications provided by the Company 
to its Trustees and officers; and (xxiii) costs of mailing, stationery and 
communications equipment. 

     (c)  All general expenses of the Company and joint expenses of the Funds 
shall be allocated among each Fund on a basis deemed fair and equitable by 
Sub-Adviser, subject to Adviser's and the Board's supervision. 

     (d)  The payment or assumption by Sub-Adviser of any expense of the 
Company or any Fund that Sub-Adviser is not required by this Contract to pay 
or assume shall not obligate Sub-Adviser to pay or assume the same or any 
similar expense of the Company or any Fund on any subsequent occasion. 

 6.  COMPENSATION.  

     (a)  For the services provided to a Fund under this Contract, Adviser 
will pay Sub-Adviser an annual fee, payable monthly, based upon the average 
daily net assets of such Fund as set forth in Appendix A hereto. 

                                  3

<PAGE>

     (b)  For the services provided under this Contract to each Fund as 
hereafter may be established, Adviser will pay to Sub-Adviser a fee in an 
amount to be agreed upon in a written Appendix to this Contract executed by 
Adviser and by Sub-Adviser. 

     (c)  The fee shall be computed daily and paid monthly to Sub-Adviser on 
or before the last business day of the next succeeding calendar month. 

     (d)  If this Contract becomes effective or terminates before the end of 
any month, the fee for the period from the effective date to the end of the 
month or from the beginning of such month to the date of termination, as the 
case may be, shall be prorated according to the proportion which such period 
bears to the full month in which such effectiveness or termination occurs. 

 7.  LIMITATION OF LIABILITY OF SUB-ADVISER AND INDEMNIFICATION.  Sub-Adviser 
shall not be liable for any costs or liabilities arising from any error of 
judgment or mistake of law or any loss suffered by the Fund or the Company in 
connection with the matters to which this Contract relates except a loss 
resulting from willful misfeasance, bad faith or gross negligence on the part 
of Sub-Adviser in the performance by Sub-Adviser of its duties or from reckless 
disregard by Sub-Adviser of its obligations and duties under this Contract. 
Any person, even though also an officer, partner, employee, or agent of 
Sub-Adviser, who may be or become a Trustee, officer, employee or agent of the 
Company, shall be deemed, when rendering services to a Fund or the Company or 
acting with respect to any business of a Fund or the Company to be rendering 
such service to or acting solely for the Fund or the Company and not as an 
officer, partner, employee, or agent or one under the control or direction of 
Sub-Adviser even though paid by it. 

 8.  DURATION AND TERMINATION.  

     (a)  This Contract shall become effective upon the date hereabove 
written, provided that this Contract shall not take effect with respect to 
any Fund unless it has first been approved (i) by a vote of a majority of the 
Independent Trustees, cast in person at a meeting called for the purpose of 
voting on such approval, and (ii) by vote of a majority of that Fund's 
outstanding voting securities, when required by the 1940 Act. 

     (b)  Unless sooner terminated as provided herein, this Contract shall 
continue in effect for two years from the above written date. Thereafter, if 
not terminated, with respect to each Fund, this Contract shall continue 
automatically for successive periods not to exceed twelve months each, 
provided that such continuance is specifically approved at least annually (i) 
by a vote of a majority of the Independent Trustees, cast in person at a 
meeting called for the purpose of voting on such approval, and (ii) by the 
Board or by vote of a majority of the outstanding voting securities of that 
Fund. 

     (c)  Notwithstanding the foregoing, with respect to any Fund this Contract
may be terminated at any time, without the payment of any penalty, by vote of
the Board or by a 

                                  4

<PAGE>

vote of a majority of the outstanding voting securities of the Fund on sixty 
days' written notice to Sub-Adviser or by Sub-Adviser at any time, without the 
payment of any penalty, on sixty days' written notice to the Company. 
Termination of this Contract with respect to one Fund shall not affect the 
continued effectiveness of this Contract with respect to any other Fund. This 
Contract will automatically terminate in the event of its assignment. 

 9.  AMENDMENT.  No provision of this Contract may be changed, waived, 
discharged or terminated orally, but only by an instrument in writing signed 
by the party against which enforcement of the change, waiver, discharge or 
termination is sought, and no amendment of this Contract shall be effective 
until approved by vote of a majority of the Fund's outstanding voting 
securities, when required by the 1940 Act. 

 10.  GOVERNING LAW.  This Contract shall be construed in accordance with the 
laws of the State of Delaware (without regard to Delaware conflict or choice 
of law provisions) and the 1940 Act. To the extent that the applicable laws

                                      BETWEEN
                                A I M ADVISORS, INC.
                                        AND
                                 INVESCO (NY), INC.

     Contract made as of December 14, 1998, between A I M Advisors, Inc., a 
Delaware corporation ("Adviser"), and INVESCO (NY), INC., a California 
corporation ("Sub-Adviser"). 

     WHEREAS Adviser has entered into an Investment Management and 
Administration Contract with GT Global Variable Investment Trust ("Company"), 
an openend management investment company registered under the Investment 
Company Act of 1940, as amended ("1940 Act"), with respect to GT Global 
Variable Strategic Income Fund and GT Global Variable U.S. Government Income 
Fund, each Fund being a series of the Company's shares of beneficial 
interest; and 

     WHEREAS Adviser desires to retain Sub-Adviser as sub-adviser to furnish 
certain advisory services to the Funds, and Sub-Adviser is willing to furnish 
such services; 

     NOW THEREFORE, in consideration of the promises and the mutual covenants 
herein contained, it is agreed between the parties hereto as follows: 

 1.  APPOINTMENT.  Adviser hereby appoints Sub-Adviser as sub-adviser of each 
Fund for the period and on the terms set forth in this Contract. Sub-Adviser 
accepts such appointment and agrees to render the services herein set forth, 
for the compensation herein provided. 

 2.  DUTIES AS SUB-ADVISER.  

     (a)  Subject to the supervision of the Company's Board of Trustees 
("Board") and Adviser, the Sub-Adviser will provide a continuous investment 
program for each Fund, including investment research and management, with 
respect to all securities and investments and cash equivalents of the Fund. 
The Sub-Adviser will determine from time to time what securities and other 
investments will be purchased, retained or sold with respect to each Fund, 
and the brokers and dealers through whom trades will be executed. 

     (b)  The Sub-Adviser agrees that, in placing orders with brokers, it will 
attempt to obtain the best net result in terms of price and execution. 
Consistent with this obligation, the Sub-Adviser may, in its discretion, 
purchase and sell portfolio securities from and to brokers and dealers who 
sell shares of the Funds or provide the Funds, Adviser's other clients, or 
Sub-Adviser's other clients with research, analysis, advice and similar 
services. The Sub-Adviser may pay to brokers and dealers, in return for such 
research and analysis, a higher commission or spread than may be charged by 
other brokers and dealers, subject to the Sub-Adviser's determining in good 
faith that such commission or spread is reasonable in 

                                  1

<PAGE>

terms either of the particular transaction or of the overall responsibility 
of the Adviser and Sub-Adviser to the Funds and their other clients and that 
the total commissions or spreads paid by each Fund will be reasonable in 
relation to the benefits to the Fund over the long term. In no instance will 
portfolio securities be purchased from or sold to the Sub-Adviser, or any 
affiliated person thereof, except in accordance with the federal securities 
laws and the rules and regulations thereunder and any exemptive orders 
currently in effect. Whenever the Sub-Adviser simultaneously places orders to 
purchase or sell the same security on behalf of a Fund and one or more other 
accounts advised by the Sub-Adviser, such orders will be allocated as to price 
and amount among all such accounts in a manner believed to be equitable to 
each account. The Company recognizes that in some cases this procedure may 
adversely affect the results attained for each Fund. 

     (c)  The Sub-Adviser will maintain all books and records with respect to 
the securities transactions of the Funds, and will furnish the Board and 
Adviser with such periodic and special reports as the Board or Adviser 
reasonably may request. In compliance with the requirements of Rule 31a-3 
under the 1940 Act, the Sub-Adviser hereby agrees that all records which it 
maintains for the Company are the property of the Company, agrees to preserve 
for the periods prescribed by Rule 31a-2 under the 1940 Act any records which 
it maintains for the Company and which are required to be maintained by 
Rule 31a-1 under the 1940 Act, and further agrees to surrender promptly to the 
Company any records which it maintains for the Company upon request by the 
Company. 

 3.  FURTHER DUTIES.  In all matters relating to the performance of this 
Contract, Sub-Adviser will act in conformity with the Agreement and 
Declaration of Trust, By-Laws and Registration Statement of the Company and 
with the instructions and directions of the Board and will comply with the 
requirements of the 1940 Act, the rules thereunder, and all other applicable 
federal and state laws and regulations. 

 4.  SERVICES NOT EXCLUSIVE.  The services furnished by Sub-Adviser hereunder 
are not to be deemed exclusive and Sub-Adviser shall be free to furnish 
similar services to others so long as its services under this Contract are 
not impaired thereby. Nothing in this Contract shall limit or restrict the 
right of any director, officer or employee of Sub-Adviser, who may also be a 
Trustee, officer or employee of the Company, to engage in any other business 
or to devote his or her time and attention in part to the management or other 
aspects of any other business, whether of a similar nature or a dissimilar 
nature. 

 5.  EXPENSES.  

     (a)  During the term of this Contract, each Fund will bear all expenses, 
not specifically assumed by Sub-Adviser, incurred in its operations and the 
offering of its shares. 

     (b)  Expenses borne by each Fund will include but not be limited to the 
following: (i) all direct charges relating to the purchase and sale of 
portfolio securities, including the cost (including brokerage commissions, if 
any) of securities purchased or sold 

                                  2

payable to and expenses incurred on behalf of the Fund by Adviser under this 
Contract; (iii) investment consulting fees and related costs; (iv) expenses

and maintaining such registrations and qualifications; (vii) costs incurred 
in connection with the issuance, sale, or repurchase of the Fund's shares of 
beneficial interest; (viii) fees and salaries payable to the Company's 
Trustees who are not parties to this Contract or interested persons of any 
such party ("Independent Trustees"); (ix) all expenses incurred in connection 
with the Independent Trustees' services, including travel expenses; (x) taxes 
(including any income or franchise taxes) and governmental fees; (xi) costs 
of any liability, uncollectible items of deposit and other insurance and 
fidelity bonds; (xii) any costs, expenses or losses arising out of a 
liability of or claim for damages or other relief asserted against the 
Company or the Fund for violation of any law; (xiii) interest charges; (xiv) 
legal, accounting and auditing expenses, including legal fees of special 
counsel for the Independent Trustees; (xv) charges of custodians, transfer

expenses the Company may incur as a result of its legal obligation to provide 
indemnification to its officers, Trustees, employees and agents) incurred by 
the Company or the Fund; (xx) fees, voluntary assessments and other expenses 
incurred in connection with membership in investment company organizations; 
(xxi) costs of mailing and tabulating proxies and costs of meetings of 
shareholders, the Board and any committees thereof; (xxii) the cost of 
investment company literature and other publications provided by the Company 
to its Trustees and officers; and (xxiii) costs of mailing, stationery and 
communications equipment. 

     (c)  All general expenses of the Company and joint expenses of the Funds 
shall be allocated among each Fund on a basis deemed fair and equitable by 
Sub-Adviser, subject to Adviser's and the Board's supervision. 

     (d)  The payment or assumption by Sub-Adviser of any expense of the 
Company or any Fund that Sub-Adviser is not required by this Contract to pay 
or assume shall not obligate Sub-Adviser to pay or assume the same or any 
similar expense of the Company or any Fund on any subsequent occasion. 

 6.  COMPENSATION.  

     (a)  For the services provided to a Fund under this Contract, Adviser 
will pay Sub-Adviser an annual fee, payable monthly, based upon the average 
daily net assets of such Fund as set forth in Appendix A hereto. 

                                  3

<PAGE>

     (b)  For the services provided under this Contract to each Fund as 
hereafter may be established, Adviser will pay to Sub-Adviser a fee in an 
amount to be agreed upon in a written Appendix to this Contract executed by 
Adviser and by Sub-Adviser. 

     (c)  The fee shall be computed daily and paid monthly to Sub-Adviser on 
or before the last business day of the next succeeding calendar month. 

     (d)  If this Contract becomes effective or terminates before the end of 
any month, the fee for the period from the effective date to the end of the 
month or from the beginning of such month to the date of termination, as the 
case may be, shall be prorated according to the proportion which such period 
bears to the full month in which such effectiveness or termination occurs. 

 7.  LIMITATION OF LIABILITY OF SUB-ADVISER AND INDEMNIFICATION.  Sub-Adviser 
shall not be liable for any costs or liabilities arising from any error of 
judgment or mistake of law or any loss suffered by the Fund or the Company in 
connection with the matters to which this Contract relates except a loss 
resulting from willful misfeasance, bad faith or gross negligence on the part 
of Sub-Adviser in the performance by Sub-Adviser of its duties or from reckless 
disregard by Sub-Adviser of its obligations and duties under this Contract. 
Any person, even though also an officer, partner, employee, or agent of 
Sub-Adviser, who may be or become a Trustee, officer, employee or agent of the 
Company, shall be deemed, when rendering services to a Fund or the Company or 
acting with respect to any business of a Fund or the Company to be rendering 
such service to or acting solely for the Fund or the Company and not as an 
officer, partner, employee, or agent or one under the control or direction of 
Sub-Adviser even though paid by it. 

 8.  DURATION AND TERMINATION.  

     (a)  This Contract shall become effective upon the date hereabove 
written, provided that this Contract shall not take effect with respect to 
any Fund unless it has first been approved (i) by a vote of a majority of the 
Independent Trustees, cast in person at a meeting called for the purpose of 
voting on such approval, and (ii) by vote of a majority of that Fund's 
outstanding voting securities, when required by the 1940 Act. 

     (b)  Unless sooner terminated as provided herein, this Contract shall 
continue in effect for two years from the above written date. Thereafter, if 
not terminated, with respect to each Fund, this Contract shall continue 
automatically for successive periods not to exceed twelve months each, 
provided that such continuance is specifically approved at least annually (i) 
by a vote of a majority of the Independent Trustees, cast in person at a 
meeting called for the purpose of voting on such approval, and (ii) by the 
Board or by vote of a majority of the outstanding voting securities of that 
Fund.

Contract may be terminated at any time, without the payment of any penalty,

                                  4

<PAGE>

vote of a majority of the outstanding voting securities of the Fund on sixty 
days' written notice to Sub-Adviser or by Sub-Adviser at any time, without the 
payment of any penalty, on sixty days' written notice to the Company. 
Termination of this Contract with respect to one Fund shall not affect the 
continued effectiveness of this Contract with respect to any other Fund. This 
Contract will automatically terminate in the event of its assignment. 

  9.  AMENDMENT.  No provision of this Contract may be changed, waived, 
discharged or terminated orally, but only by an instrument in writing signed 
by the party against which enforcement of the change, waiver, discharge or 
termination is sought, and no amendment of this Contract shall be effective 
until approved by vote of a majority of the Fund's outstanding voting 
securities, when required by the 1940 Act. 

 10.  GOVERNING LAW.  This Contract shall be construed in accordance with the 
laws of the State of Delaware (without regard to Delaware conflict or choice 
of law provisions) and the 1940 Act. To the extent that the applicable laws 
of the State of Delaware conflict with the applicable provisions of the 1940 
Act, the latter shall control. 

 11.  MISCELLANEOUS.  The captions in this Contract are included for 
convenience of reference only and in no way define or delimit any of the 
provisions hereof or otherwise affect their construction or effect. If any 
provision of this Contract shall be held or made invalid by a court decision,

shall reimburse AIM for certain expenses that it incurs in rendering services 
with respect to that Fund under this Agreement.

SECTION 6.  RELIANCE BY AIM ON INSTRUCTIONS.  Unless otherwise provided in 
this Agreement, AIM shall act only upon Oral or Written Instructions.  AIM 
shall be entitled to rely upon any such Instructions actually received by it 
under this Agreement.  The Company agrees that AIM shall incur no liability

SECTION 7.  COOPERATION WITH AGENTS OF THE COMPANY.  AIM shall cooperate with

SECTION 8.  CONFIDENTIALITY.  AIM, on behalf of itself and its employees, 
agrees to treat confidentially all records and other information relating to 
the Company and the Funds except when requested to divulge such information

withheld and may not be withheld if AIM, in its judgment, may be subject to 
civil or criminal contempt proceedings for failure to comply.

SECTION 9.  STANDARD OF CARE.  In the performance of its responsibilities 
hereunder, AIM shall exercise care and diligence in the performance of its 
duties and act in good faith and use its best efforts to ensure the accuracy

               (a)  shall be under no duty to take any action on behalf of

<PAGE>

sources of quotations to be used in computing net asset value, (4) as to the 
fair value to be assigned to any securities or other property for which price 
quotations are not readily available and (5) as to the sources of information 
with respect to "corporate actions" affecting portfolio securities of a Fund 
(information as to "corporate actions" shall include information as to 
dividends, distributions, interest payments, prepayments, stock splits, stock 
dividends, rights offerings, conversions, exchanges, recapitalizations,

               (b)  shall be responsible and liable for all losses, damages 
and costs (including reasonable attorneys' fees) incurred by the Company or 
any Fund which is due to or caused by AIM's negligence in the performance of 
its duties under this Agreement or for AIM's negligent failure to perform 
such duties as are specifically assumed by AIM in this Agreement, provided 
that, to the extent that duties, obligations and responsibilities are not 
expressly set forth in this Agreement, AIM shall not be liable for any act or 
omission that does not constitute willful misfeasance, bad faith or 
negligence on the part of AIM or reckless disregard by AIM of such duties, 
obligations and responsibilities; and

               (c)  without limiting the generality of the foregoing, AIM 
shall not, in connection with AIM's duties under this Agreement, be under any 
duty or obligation to inquire into and shall not be liable for or in respect 
of:

                    (1)  the validity or invalidity or authority or lack of 
authority of any Oral or Written Instruction, notice or other instrument 
which conforms to the applicable requirements of this Agreement, if any, and 
that AIM reasonably believes to be genuine; and

                    (2)  delays or errors or loss of data occurring by reason 
of circumstances beyond AIM's control including, without limitation, acts of 
civil or military authorities, national emergencies, labor difficulties, 
fire, mechanical breakdown, denial of access, earthquake, flood or 
catastrophe, acts of God, insurrection, war, riots, or failure of the mails, 
transportation, communication or power supply.

Notwithstanding any other provisions of this Agreement, the following 
provisions shall apply with respect to AIM's computation of a Fund's net 
asset value:  AIM shall be held to the exercise of reasonable care in 
computing and determining net asset value as provided in Section 4(a), above, 
but shall not be held accountable or liable for any losses, damages or 
expenses of a Fund or any Shareholder or former Shareholder may incur arising 
from or based upon errors or delays in the determination of such net asset 
value unless such error or delay was due to AIM's negligence or willful 
misfeasance in the computation and determination of such net asset value.  
The parties hereto acknowledge, however, that AIM causing an error or delay 
in the determination of net asset value may, but does not in an of itself, 
constitute negligence or willful misfeasance.  In no event shall AIM be 
liable or responsible to the Company or a Fund or any other party for any 
error or delay which continued or was undetected after the date of an audit 
of the Company or any Fund performed by the certified public accountants 
employed by the Company if, in the exercise of reasonable care in accordance 
with generally accepted accounting principles, such accountants should have 
become aware of such error or delay in the course of performing such audit.  
AIM's liability for any such negligence or willful misfeasance which 

                                  5

<PAGE>

results in an error in determination of such  net asset value be limited to 
the direct out-of-pocket loss a Fund and/or any Shareholder or former 
Shareholder shall actually incur.

               Without limiting the generality of the foregoing, AIM shall 
not be held accountable or liable to a Fund, a Shareholder or former 
Shareholder or any other person for any delays or losses, damages or expenses 
any of them may suffer or incur resulting from (1) AIM's failure to receive 
timely and suitable notification concerning quotations, corporate actions or 
similar matters relating to or affecting portfolio securities of a Fund or 
(2) any errors in the computation of a net asset value based upon or arising 
out of quotations or information as to corporate actions if received by AIM 
from a source that AIM was authorized to rely upon. Nevertheless, AIM will 
use its best judgment in determining whether to verify through other sources 
any information that it has received as to quotations or corporate actions if 
AIM has reason to believe that any such information is incorrect.

SECTION 10.  RECEIPT OF ADVICE.  If AIM is in doubt as to any action to be 
taken or omitted by it, AIM may request, and shall be entitled to rely upon, 
directions and advice from the Company, including Oral or Written 
Instructions where appropriate, or from counsel of its own choosing (who may 
also be counsel for the Company or any Fund), with respect to any question of 
law.  In case of conflict between directions, advice or Oral and Written 
Instructions received by AIM pursuant to this Section, AIM shall be entitled 
to rely on and follow the advice received from counsel as described above.  
AIM shall be protected in any action or in action that it takes in reliance 
on any directions, advice or Oral or Written Instructions received pursuant 
to this Section that AIM, after the receipt of the same, in good faith 
believes to be consistent with such directions, advice or Oral or Written 
Instructions, as the case may be. Notwithstanding the foregoing, nothing in 
this Section shall be construed as imposing on AIM any obligation to seek 
such directions, advice or Oral or Written Instruction, or to act in 
accordance with them when received, unless the same is a condition to AIM's 
properly taking or omitting to take such action under the terms of this 
Agreement.

SECTION 11.  INDEMNIFICATION OF AIM.  The Company agrees to indemnify and 
hold harmless AIM and its officers, directors, employees, nominees and

reasonable attorneys' fees and disbursements, arising directly or indirectly 
from any action or omission of AIM that does not meet the standard of care to 
which AIM is subject under Section 9, above.

COMPANY.  It is expressly agreed that the obligations of the Company 
hereunder shall not be binding upon any of the shareholders, trustees,

any of them individually or to impose any liability on any of them 
personally, but shall bind only the assets and property of the applicable

SECTION 14.  DURATION AND TERMINATION.  This Agreement shall continue with 
respect to the Company and each Fund until termination with respect to the 
Company, or with respect to one or more Funds, is effected by the Company or 
AIM upon sixty days' prior written notice to the other.  In the event of the 
"assignment" of this Agreement within the meaning of the 1940 Act, this 
Agreement shall terminate automatically.

SECTION 15.  NOTICES.  All notices and other communications hereunder, 
including Written Instructions, shall be in writing or by confirming

                                   TO
                            FUND ACCOUNTING 
                                   AND 
                        PRICING AGENT AGREEMENT
                                   FOR
                    GT GLOBAL VARIABLE INVESTMENT TRUST


                  FUND ACCOUNTING AND PRICING AGENT FEES

               Each Fund shall pay a Fee to AIM determined as a percentage of 
the Fund's net assets. The annualized rate at which the fee is paid (the Fee 
Rate) and the Fee shall be calculated as set forth below:

 - An ASSET MULTIPLIER is determined by multiplying 0.0003 times the first 
$5 billion in average net assets of the AIM Funds plus 0.0002 times such net 
assets over $5 billion.

 - The FEE RATE is determined by dividing the Asset Multiplier by the net 
assets of the AIM Funds.

 - The MONTHLY FEE is determined then by multiplying the average daily Fee 
Rate by the number of days in the month and by the Fund's average daily net 
assets then dividing by 365/or 366, as appropriate.

Example:  For Fund X having $100 million in average net assets during December
1997, in which the AIM Funds have average net assets of $8 billion:


Asset Multiplier = (0.0003) ($5 billion) + (0.0002) ($3 billion) = $2.1 million

Fee Rate = $2.1 million = 0.0002625
           ------------
            $8 billion

Monthly Fee = (   31  ) (0.0002625) ($100 million) = $2,229.45
              ---------
               ( 365  )
