        PROSPECTUS
        MAY 3, 1999
 
                                       This prospectus contains important
                                       information. Please read it before
                                       investing and keep it for future
                                       reference.
 
                                       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. There is a risk
                                       that you could lose a portion or all
                                       of your money.
 
                                       As with all other mutual fund
                                       securities, the Securities and
                                       Exchange Commission has not approved
                                       or disapproved these securities or
                                       determined whether the information
                                       in this prospectus is adequate or
                                       accurate. Anyone who tells you
                                       otherwise is committing a crime.

                        AIM V.I. AGGRESSIVE GROWTH FUND
                        -------------------------------
 
INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's investment objective is to achieve long-term growth of capital.
 
  The fund seeks to meet this objective by investing primarily in common stocks,
convertible bonds, convertible preferred stocks and warrants of small- and
medium-sized companies whose earnings the fund's portfolio managers expect to
grow more than 15% per year. The fund may also invest up to 25% of its total
assets in foreign securities.
 
  The portfolio managers focus on companies they believe are likely to benefit
from new or innovative products, services or processes as well as those that
have experienced above-average, long-term growth in earnings and have excellent
prospects for future growth. The portfolio managers consider whether to sell a
particular security when any of those factors materially changes.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instruments, bonds or other
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, the value of its assets, general economic
conditions, interest rates, investor perceptions and market liquidity. This is
especially true with respect to common stocks of smaller companies, whose prices
may go up and down more than common stocks of larger, more-established
companies. Also, since common stocks of smaller companies may not be traded as
often as common stocks of larger, more-established companies, it may be
difficult or impossible for the fund to sell securities at a desirable price.
 
  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.
 
These factors may affect the prices of securities 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 devaluated 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.
 
  If the seller of a repurchase agreement in which the fund invests defaults on
its obligation or declares bankruptcy, the fund may experience delays in selling
the securities underlying the repurchase agreement. As a result, the fund may
incur losses arising from decline in the value of those securities, reduced
levels of income and expenses of enforcing its rights.
 
  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 its 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.

FUND MANAGEMENT
- --------------------------------------------------------------------------------
 
THE ADVISOR
 
A I M Advisors, Inc. (the advisor) serves as the fund's investment advisor . The
advisor is located at 11 Greenway Plaza, Suite 100, Houston, Texas 77046-1173.
The advisor supervises all aspects of the fund's operations and provides
investment advisory services to the fund, including obtaining and evaluating
economic, statistical and financial information to formulate and implement
investment programs for the fund.
 
  The advisor has acted as an investment advisor since its organization in 1976.
Today, the advisor, together with its subsidiaries, advises or manages over 110
investment portfolios, including the fund, encompassing a broad range of
investment objectives.
 
ADVISOR COMPENSATION
 
The advisor is to receive a fee from the fund calculated at the annual rate of
0.80% of the first $150 million of average daily net assets and 0.625% of
average daily net assets over $150 million.
 
PORTFOLIO MANAGERS
 
The advisor uses a team approach to investment management. The individual
members of the team who are primarily responsible for the day-to-day management
of the fund's portfolio, all of whom are officers of A I M Capital Management,
Inc., a wholly owned subsidiary of the advisor, are
 
- - Robert M. Kippes, Senior Portfolio Manager, who has been responsible for the
  fund since 1998 and has been associated with the advisor and/or its affiliates
  since 1989.
 
- - Kenneth A. Zschappel, Senior Portfolio Manager, who has been responsible for
  the fund since 1998 and has been associated with the advisor and/or its
  affiliates since 1990.
 
- - Charles D. Scavone, Senior Portfolio Manager, who has been responsible for the
  fund since 1998 and has been associated with the advisor and/or its affiliates
  since 1996. From 1994 to 1996, Mr. Scavone was Associate Portfolio Manager for
  the Van Kampen American Capital Asset Management, Inc.
 
- - Ryan E. Crane, Portfolio Manager, who has been responsible for the fund since
  1999 and has been associated with the advisor and/or its affiliates since
  1994.

OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares at the fund's
next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.
 
PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.
 
TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisors before investing.
 
DIVIDENDS AND DISTRIBUTIONS

DIVIDENDS
 
The fund generally declares and pays dividends, if any, annually to separate
accounts of participating life insurance companies.

CAPITAL GAINS DISTRIBUTIONS
 
The fund generally distributes long-term and short-term capital gains (including
any net gains from foreign currency transactions), if any, annually to separate
accounts of participating life insurance companies.
 
  At the election of participating life insurance companies, dividends and
distributions are automatically reinvested at net asset value in shares of the
fund.
 
FUTURE FUND CLOSURE
 
Due to the sometime limited availability of common stocks of small-cap companies
that meet the investment criteria for AIM V.I. Aggressive Growth Fund, the fund
may periodically suspend or limit the offering of its shares and it will be
closed to new participants when fund assets reach $200 million.
 
  During closed periods, the fund will accept additional investments from
existing participants.

                                       information. Please read it before

                                       An investment in the fund is not a
                                       deposit of a bank and is not insured
                                       or guaranteed by the Federal Deposit

                             AIM V.I. BALANCED FUND
                             ----------------------
 
INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's investment objective is to achieve as high a total return as
possible, consistent with preservation of capital.
 
  The fund seeks to meet this objective by investing in a broadly diversified
portfolio of high-yielding securities, including common stocks, preferred
stocks, convertible securities and bonds. The fund normally invests a minimum of
30% and a maximum of 70% of its total assets in equity securities and a minimum
of 30% and a maximum of 70% of its total assets in non-convertible debt
securities. The fund may also invest up to 25% of its total assets in
convertible securities. The fund may invest up to 10% of its total assets in
lower-quality debt securities, i.e., "junk bonds." The fund may also invest up
to 20% of its total assets in foreign securities.
 
  In selecting the percentages of assets to be invested in equity or debt
securities, the portfolio managers consider such factors as the general market
and economic conditions, as well as trends, yields, interest rates and changes
in fiscal and monetary policies. The portfolio managers will primarily purchase
equity securities for growth of capital and debt securities for income purposes.
However, the portfolio managers will focus on companies whose securities have
the potential for both growth of capital and income generation. The portfolio
managers consider whether to sell a particular security when they believe that
security no longer has that potential.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instruments, bonds or other
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 and that the income you may receive from the fund may vary. 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 price 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. Interest rate increases may
cause the price of a debt security to decrease; the longer a debt security's
duration, the more sensitive it is to this risk. The issuer of a security may
default or otherwise be unable to honor a financial obligation.
 
  The values of convertible securities in which the fund invests may also be
affected by market interest rates, the risk that the issuer may default on
interest or principal payments and the value of the underlying stock into which
these securities may be converted. Specifically, since these types of
convertible securities pay fixed interest or dividends, their values may fall if
interest rates rise. Additionally, an issuer may have the right to buy back
certain of the convertible securities at a time and at a price that is
unfavorable to the fund.
 
  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.
 
These factors may affect the prices of securities 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 devaluated 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.
 
  If the seller of a repurchase agreement in which the fund invests defaults on
its obligation or declares bankruptcy, the fund may experience delays in selling
the securities underlying the repurchase agreement. As a result, the fund may
incur losses arising from decline in the value of those securities, reduced
levels of income and expenses of enforcing its rights.
 
  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 its 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.

OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares at the fund's
next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.
 
PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.
 
TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisors before investing.
 
DIVIDENDS AND DISTRIBUTIONS
   
    
DIVIDENDS
 
The fund generally declares and pays dividends, if any, annually to separate
accounts of participating life insurance companies.
   
    
CAPITAL GAINS DISTRIBUTIONS
 
The fund generally distributes long-term and short-term capital gains (including
any net gains from foreign currency transactions), if any, annually to separate
accounts of participating life insurance companies.
 
  At the election of participating life insurance companies, dividends and
distributions are automatically reinvested at net asset value in shares of the
fund.

                       ----------------------------------
 
INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's investment objective is growth of capital through investment in
common stocks, with emphasis on medium- and small-sized growth companies.
 
  The fund may also invest up to 20% of its total assets in foreign securities.
 
  The portfolio managers focus on companies they believe are likely to benefit
from new or innovative products, services or processes as well as those that
have experienced above-average, long-term growth in earnings and have excellent
prospects for future growth. The portfolio managers consider whether to sell a
particular security when any of those factors materially changes.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instruments, bonds or other
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, the value of its assets, general economic
conditions, interest rates, investor perceptions and market liquidity. This is
especially true with respect to common stocks of smaller companies, whose prices
may go up and down more than common stocks of larger, more-established
companies. Also, since common stocks of smaller companies may not be traded as
often as common stocks of larger, more-established companies, it may be
difficult or impossible for the fund to sell securities at a desirable price.
 
  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.
 
These factors may affect the prices of securities 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 devaluated 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 its 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.

FUND MANAGEMENT
- --------------------------------------------------------------------------------
 
THE ADVISOR
 
A I M Advisors, Inc. (the advisor) serves as the fund's investment advisor. The
advisor is located at 11 Greenway Plaza, Suite 100, Houston, Texas 77046-1173.
The advisor supervises all aspects of the fund's operations and provides
investment advisory services to the fund, including obtaining and evaluating
economic, statistical and financial information to formulate and implement
investment programs for the fund.
 
  The advisor has acted as an investment advisor since its organization in 1976.
Today, the advisor, together with its subsidiaries, advises or manages over 110
investment portfolios, including the fund, encompassing a broad range of
investment objectives.
 
ADVISOR COMPENSATION
 
During the fund's last fiscal year ended December 31, 1998, the advisor received
compensation of 0.62% of average net assets.
 
PORTFOLIO MANAGERS
 
The advisor uses a team approach to investment management. The individual
members of the team who are primarily responsible for the day-to-day management
of the fund's portfolio, all of whom are officers of A I M Capital Management,
Inc., a wholly owned subsidiary of the advisor, are
 
- - Robert M. Kippes, Senior Portfolio Manager, who has been responsible for the
  fund since 1993 and has been associated with the advisor and/or its affiliates

OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares at the fund's
next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.
 
PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.
 
TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisors before investing.

accounts of participating life insurance companies.

CAPITAL GAINS DISTRIBUTIONS
 
The fund generally distributes long-term and short-term capital gains (including
any net gains from foreign currency transactions), if any, annually to separate
accounts of participating life insurance companies.
 
  At the election of participating life insurance companies, dividends and
distributions are automatically reinvested at net asset value in shares of the
fund.
 
FINANCIAL HIGHLIGHTS
- --------------------------------------------------------------------------------
 
The financial highlights table is intended to help you understand the fund's
financial performance. Certain information reflects financial results for a
single fund share.

                                       information. Please read it before

                                       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. There is a risk
                                       that you could lose a portion or all

                                       securities, the Securities and
                                       Exchange Commission has not approved
                                       or disapproved these securities or

                       ---------------------------------
 
INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's investment objective is long-term growth of capital.
 
  The fund seeks to meet this objective by investing primarily in securities,
including common stocks, convertible securities and bonds, of small- and
medium-sized companies. The fund may also invest up to 25% of its total assets
in foreign securities.
 
  Among factors which the portfolio managers may consider when purchasing these
securities are: (1) the growth prospects for a company's products; (2) the
economic outlook for its industry; (3) a company's new product development; (4)
its operating management capabilities; (5) the relationship between the price of
the security and its estimated fundamental value; (6) relevant market, economic
and political environments; and (7) financial characteristics, such as balance
sheet analysis and return on assets. The portfolio managers sell a particular
security when any one of these factors materially changes or when the securities
are no longer considered medium-sized company securities.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instruments, bonds or other
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, the value of its assets, general economic
conditions, interest rates, investor perceptions and market liquidity. This is
especially true with respect to common stocks of smaller companies, whose prices
may go up and down more than common stock of larger, more-established companies.
Also, since common stock of smaller companies may not be traded as often as
common stock of larger, more-established companies, it may be difficult or
impossible for the fund to sell securities in the fund at a desirable price.
 
  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.
 
These factors may affect the prices of securities 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 devaluated 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 its 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.

FUND MANAGEMENT
- --------------------------------------------------------------------------------
 
THE ADVISOR
 
A I M Advisors, Inc. (the advisor) serves as the fund's investment advisor. The
advisor is located at 11 Greenway Plaza, Suite 100, Houston, Texas 77046-1173.
The advisor supervises all aspects of the fund's operations and provides
investment advisory services to the fund, including obtaining and evaluating
economic, statistical and financial information to formulate and implement
investment programs for the fund.
 
  The advisor has acted as an investment advisor since its organization in 1976.
Today, the advisor, together with its subsidiaries, advises or manages over 110
investment portfolios, including the fund, encompassing a broad range of
investment objectives.
 
ADVISOR COMPENSATION
 
The advisor is to receive a fee from the fund calculated at the annual rate of
0.75% of the first $350 million of average daily net assets and 0.625% of
average daily net assets over $350 million.
 
PORTFOLIO MANAGERS
 
The advisor uses a team approach to investment management. The individual
members of the team who are primarily responsible for the day-to-day management
of the fund's portfolio, all of whom are officers of A I M Capital Management,
Inc., a wholly owned subsidiary of the advisor, are
 
- - Edgar M. Larsen, Senior Portfolio Manager, who has been responsible for the
  fund since 1998 and has been associated with the advisor and/or its affiliates
  since 1996. From 1981 to 1996 Mr. Larsen was among other offices, Senior Vice
  President and portfolio manager for John Hancock Advisers, Inc. and its
  predecessors.
 
- - Paul J. Rasplicka, Senior Portfolio Manager, who has been responsible for the
  fund since 1998 and has been associated with the advisor and/or its affiliates
  since 1994.
 
OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares at the fund's
next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.
 
PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.
 
TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisors before investing.
 
DIVIDENDS AND DISTRIBUTIONS

DIVIDENDS
 
The fund generally declares and pays dividends, if any, annually to separate
accounts of participating life insurance companies.

CAPITAL GAINS DISTRIBUTIONS
 
The fund generally distributes long-term and short-term capital gains (including
any net gains from foreign currency transactions), if any, annually to separate
accounts of participating life insurance companies.
 
  At the election of participating life insurance companies, dividends and
distributions are automatically reinvested at net asset value in shares of the
fund.

                        AIM V.I. DIVERSIFIED INCOME FUND
                        -------------------------------- 
 

INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's investment objective is to achieve a high level of current income.
 
  The fund seeks to meet this objective by investing primarily in (1) domestic
and foreign corporate debt securities; (2) U.S. Government securities, including
U.S. Government agency mortgage-backed securities; (3) securities issued by
foreign governments, their agencies or instrumentalities, and (4) lower-quality
debt securities, i.e., "junk bonds," of U.S. and foreign companies. The fund's
assets will normally be invested in each of these four sectors, however the fund
may invest up to 100% of its total assets in U.S. Government securities.
 
  The fund may invest up to 50% of its total assets in foreign securities,
including securities of issuers located in developing countries. The fund may
invest up to 25% of its total assets in government securities of any one foreign
country. The fund may also invest up to 10% of its total assets in equity
securities and convertible debt securities of U.S. and foreign companies. The
fund may invest in debt obligations issued by certain supranational entities,
such as the World Bank.
 
  The portfolio managers focus on securities that they believe have favorable
prospects for current income, whether denominated in the U.S. dollar or in other
currencies. The portfolio managers consider whether to sell a particular
security when any of those factors materially changes.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instruments, bonds or other
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 and that the income you may receive from your investment may vary. The
value of your investment in the fund will go up and down with the prices of the
securities in which the fund invests. Debt securities are particularly
vulnerable to credit risk and interest rate fluctuations. Interest rate
increases may cause the price of a debt security to decrease. The longer a debt
security's duration, the more sensitive it is to this risk. Junk bonds are less
sensitive to risk than are higher-quality bonds. Some of the securities
purchased by the fund are not guaranteed by the U.S. Government. The agency or
instrumentality issuing such security may default or otherwise be unable to
honor a financial obligation.
 
  Compared to higher-quality debt securities, junk bonds involve greater risk of
default or price changes due to changes in the credit quality of the issuer
because they are generally unsecured and may be subordinated to other creditors'
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 could be difficult to value or sell at a fair
price. Credit ratings on junk bonds do not necessarily reflect their actual
market 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 more volatile than U.S. securities.
 
These factors may affect the prices of securities 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 devaluated 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.
 
  U.S. Government agency mortgage-backed securities provide a higher coupon at
the time of purchase than current prevailing market interest rates. The fund may
purchase such securities at a premium, which means that a faster principal
prepayment rate than expected will reduce both the market value of and income
from such securities.
 
  The prices of equity securities fluctuates 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 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 its 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.

PERFORMANCE INFORMATION

FUND MANAGEMENT
- --------------------------------------------------------------------------------
 
THE ADVISOR
 
A I M Advisors, Inc. (the advisor) serves as the fund's investment advisor. The
advisor is located at 11 Greenway Plaza, Suite 100, Houston, Texas 77046-1173.
The advisor supervises all aspects of the fund's operations and provides
investment advisory services to the fund, including obtaining and evaluating

  The advisor has acted as an investment advisor since its organization in 1976.
Today, the advisor, together with its subsidiaries, advises or manages over 110
investment portfolios, including the fund, encompassing a broad range of
investment objectives.
 
ADVISOR COMPENSATION
 
During the fund's last fiscal year ended December 31, 1998, the advisor received
compensation of 0.60% of average net assets.
 
PORTFOLIO MANAGERS
 
The advisor uses a team approach to investment management. The individual
members of the team who are primarily responsible for the day-to-day management
of the fund's portfolio, all of whom are officers of A I M Capital Management,
Inc., a wholly owned subsidiary of the advisor, are
 
- - Robert G. Alley, Senior Portfolio Manager, who has been responsible for the

OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares received at the
fund's next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.
 
PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.
 
TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisors before investing.
 
DIVIDENDS AND DISTRIBUTIONS

   
    
DIVIDENDS
 
The fund generally declares and pays dividends, if any, annually to separate
accounts of participating life insurance companies.
 
CAPITAL GAINS DISTRIBUTIONS
 
The fund generally distributes long-term and short-term capital gains (including
any net gains from foreign currency transactions), if any, annually to separate
accounts of participating life insurance companies.
 
  At the election of participating life insurance companies, dividends and
distributions are automatically reinvested at net asset value in shares of the
fund.

                         ------------------------------
 
INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's investment objectives are to achieve a high level of current income
and secondarily, growth of capital, by investing primarily in the common and
preferred stocks of public utility companies (either domestic or foreign).
 
  The fund seeks to meet these objectives by investing, normally, at least 65%
of its total assets in securities of domestic and foreign public utility
companies. Public utility companies include companies that provide electricity,
natural gas, water and sanitary services to the public, telephone or telegraph
companies, and other companies providing public communications services. The
fund may also invest in developing utility technology companies and in holding
companies that derive a substantial portion of their revenues from utility
related activities.
 
  The fund may invest up to 80% of its total assets in foreign securities,
including securities of issuers located in developing countries. Developing
countries are those countries that are in the initial stages of their industrial
cycles. The fund will normally invest in the securities of companies located in
at least four different countries, including the United States. The fund may
invest up to 25% of its total assets in convertible securities of public utility
companies. The fund may also invest up to 25% of its total assets in public
utility company, non-convertible bonds. The fund may invest up to 10% of its
total assets in lower-quality debt securities, i.e., "junk bonds."
 
  The portfolio managers focus on securities that have favorable prospects for
high current income and growth of capital. The portfolio managers consider
whether to sell a particular security when any of those factors materially
changes.
 
  The fund is a non-diversified portfolio. With respect to 50% of its total
assets, it is permitted to invest more than 5% of its assets in the securities
of any one issuer.
 
  In anticipation of or in response to adverse market conditions, the fund may
invest up to 100% of its total assets in securities of U.S. issuers.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instruments, bonds or other
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 and that the income you may receive from the fund may vary. 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, the value of its assets, general economic conditions, interest
rates, investor perceptions and market liquidity. Interest rate increases may
cause the price of a debt security to decrease; the longer a debt security's
duration, the more sensitive it is to this risk. The issuer of a security may
default or otherwise be unable to honor a financial obligation.
 
  The value of the fund's shares is particularly vulnerable to factors affecting
the utility company industry, such as substantial economic, operational or
regulatory changes. Such changes may, among other things, increase compliance
costs or the costs of doing business. In addition, increases in fuel, energy and
other prices have historically limited the growth potential of utility
companies. Because the fund focuses its investments in the public utility
industry, 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 valued.
 
- - Political and economic conditions--The value of the fund's foreign investments
  may be adversely affected by political and social instability in 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.
 
These factors may affect the prices of securities 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 devaluated 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
were a diversified fund. 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 its 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.

FUND MANAGEMENT
- --------------------------------------------------------------------------------
 
THE ADVISOR
 
A I M Advisors, Inc. (the advisor) serves as the fund's investment advisor. The
advisor is located at 11 Greenway Plaza, Suite 100, Houston, Texas 77046-1173.
The advisor supervises all aspects of the fund's operations and provides
investment advisory services to the fund, including obtaining and evaluating
economic, statistical and financial information to formulate and implement
investment programs for the fund.
 
  The advisor has acted as an investment advisor since its organization in 1976.
Today, the advisor, together with its subsidiaries, advises or manages over 110
investment portfolios, including the fund, encompassing a broad range of
investment objectives.
 
ADVISOR COMPENSATION
 
During the fund's last fiscal year ended December 31, 1998, the advisor received
compensation of 0.65% of average net assets.
 
PORTFOLIO MANAGERS
 
The advisor uses a team approach to investment management. The individual
members of the team who are primarily responsible for the day-to-day management
of the fund's portfolio, all of whom are officers of A I M Capital Management,
Inc., a wholly owned subsidiary of the advisor, are
 
- - Claude C. Cody, IV, Senior Portfolio Manager, who has been responsible for the
  fund since 1998 and has been associated with the advisor and/or its affiliates

OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares at the fund's
next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.
 
PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.
 
TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisors before investing.
 
DIVIDENDS AND DISTRIBUTIONS

DIVIDENDS
 
The fund generally declares and pays dividends, if any, annually to separate
accounts of participating life insurance companies.

CAPITAL GAINS DISTRIBUTIONS
 
The fund generally distributes long-term and short-term capital gains (including
any net gains from foreign currency transactions), if any, annually to separate
accounts of participating life insurance companies.
 
  At the election of participating life insurance companies, dividends and
distributions are automatically reinvested at net asset value in shares of the
fund.

        principal by investing in debt securities issued, guaranteed or
        otherwise backed by the United States Government.

        PROSPECTUS
        MAY 3, 1999
 
                                       This prospectus contains important
                                       information. Please read it before
                                       investing and keep it for future
                                       reference.
 
                                       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. There is a risk
                                       that you could lose a portion or all
                                       of your money.
 
                                       As with all other mutual fund
                                       securities, the Securities and
                                       Exchange Commission has not approved
                                       or disapproved these securities or
                                       determined whether the information

                                       accurate. Anyone who tells you
                                       otherwise is committing a crime.

                      AIM V.I. GOVERNMENT SECURITIES FUND
                      -----------------------------------
 
INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's investment objective is to achieve a high level of current income
consistent with reasonable concern for safety of principal by investing in debt
securities issued, guaranteed or otherwise backed by the United States
Government.
 
  The fund may invest in securities of all maturities issued or guaranteed by
the U.S. Government or its agencies and instrumentalities, including: (1) U.S.
Treasury obligations, and (2) obligations issued or guaranteed by U.S.
Government agencies and instrumentalities and supported by (a) the full faith
and credit of the U.S. Treasury, (b) the right of the issuer to borrow from the
U.S. Treasury, or (c) the credit of the agency or instrumentality. The fund
intends to maintain a dollar-weighted average portfolio maturity of between
three and ten years. The fund may invest in high-coupon U.S. Government agency
mortgage-backed securities, which consist of interests in underlying mortgages
with maturities of up to thirty years. The fund may also invest up to 20% of its
assets in foreign securities.
 
  The portfolio managers focus on securities that they believe have favorable
prospects for current income, consistent with their concern for safety of
principal. The portfolio managers consider whether to sell a particular security
when any of those factors materially changes.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instruments, bonds or other
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 and that the income you may receive from your investment may vary. The
value of your investment in the fund will go up and down with the prices of the
securities in which the fund invests. Debt securities are particularly
vulnerable to credit risk and interest rate fluctuations. Interest rate
increases can cause the price of a debt security to decrease. The longer a debt
security's duration, the more sensitive it is to this risk. The prices of
high-coupon U.S. Government agency mortgage-backed securities fall more slowly
when interest rates rise than do prices of other fixed-rate securities. Some of
the securities purchased by the fund are not guaranteed by the U.S. Government.
The agency or instrumentality issuing such security may default or otherwise be
unable to honor a financial obligation.
 
  High-coupon U.S. Government agency mortgage-backed securities provide a higher
coupon at the time of purchase than current prevailing market interest rates.
The fund may purchase such securities at a premium. If the securities experience
a faster principal prepayment rate than expected, both the market value of, and
income from, such securities will decrease.
 
  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.
 
These factors may affect the prices of securities 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 devaluated 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 its 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.

FUND MANAGEMENT
- --------------------------------------------------------------------------------
 
THE ADVISOR
 
A I M Advisors, Inc. (the advisor) serves as the fund's investment advisor. The
advisor is located at 11 Greenway Plaza, Suite 100, Houston, Texas 77046-1173.
The advisor supervises all aspects of the fund's operations and provides
investment advisory services to the fund, including obtaining and evaluating
economic, statistical and financial information to formulate and implement
investment programs for the fund.
 
  The advisor has acted as an investment advisor since its organization in 1976.
Today, the advisor, together with its subsidiaries, advises or manages over 110
investment portfolios, including the fund, encompassing a broad range of
investment objectives.
 
ADVISOR COMPENSATION
 
During the fund's last fiscal year ended December 31, 1998, the advisor received
compensation of 0.50% of the fund's average net assets.
 
PORTFOLIO MANAGERS
 
The advisor uses a team approach to investment management. The individual
members of the team who are primarily responsible for the day-to-day management
of the fund's portfolio, all of whom are officers of A I M Capital Management,
Inc., a wholly owned subsidiary of the advisor, are

OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares at the fund's
next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.
 
PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.
 
TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisors before investing.
 
DIVIDENDS AND DISTRIBUTIONS

DIVIDENDS
 
The fund generally declares and pays dividends, if any, annually to separate
accounts of participating life insurance companies.

CAPITAL GAINS DISTRIBUTIONS
 
The fund generally distributes long-term and short-term capital gains (including
any net gains from foreign currency transactions), if any, annually to separate
accounts of participating life insurance companies.
 
  At the election of participating life insurance companies, dividends and
distributions are automatically reinvested at net asset value in shares of the
fund.

        PROSPECTUS
        MAY 3, 1999
 
                                       This prospectus contains important
                                       information. Please
                                       read it before investing and keep it
                                       for future reference.
 
                                       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. There is a risk
                                       that you could lose a portion or all
                                       of your money.
 
                                       As with all other mutual fund
                                       securities, the Securities and
                                       Exchange Commission has not approved
                                       or disapproved these securities or
                                       determined whether the information
                                       in this prospectus is adequate or

                     AIM V.I. GLOBAL GROWTH AND INCOME FUND
                     --------------------------------------
 
INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's investment objectives are long-term growth of capital together with
current income.
 
  The fund seeks to meet this 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 Ratings
Services, or are deemed by the portfolio managers to be of comparable quality.
 
  The fund may invest up to 35% of its total assets in other equity securities,
convertible securities and government and corporate debt securities that are
investment grade, i.e., rated within one of the four highest ratings categories
of Moody's or S&P. The fund may purchase debt obligations issued or guaranteed
by the U.S. or foreign governments, including foreign states, provinces or
municipalities, or their agencies, authorities or instrumentalities and debt
obligations of supranational organizations, such as the World Bank. 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 in the securities of issuers located in developing countries,
i.e., those that are in the initial stages of their industrial cycles. 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
objectives are expected to be the most attractive. The portfolio managers
consider whether to sell a particular security when opportunities for meeting
the fund's investment objectives are no longer considered attractive.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instruments, bonds or other
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 and that the income you may receive from your investment may vary. 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, 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. Interest
rate increases may cause the price of a debt security to decrease. The longer a
debt security'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 more volatile than U.S. securities.
 
These factors may affect the prices of securities issued by foreign companies
located in developing or emerging market 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 its 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.

A I M Advisors, Inc. (the advisor) serves as the fund's investment advisor and
is responsible for its day-to-day management including the fund's investment
decisions and the execution of securities transactions. The advisor is located
at 11 Greenway Plaza, Suite 100, Houston, Texas 77046-1173. INVESCO Asset
Management Limited (the subadvisor), serves as the fund's subadvisor, is located
at 11 Devonshire Square, London, England EC2M4YR. The subadvisor is responsible
for providing the advisor with economic and market research, securities analysis
and investment recommendations with respect to the fund. Both entities are
affiliated.
 
  The advisor has acted as an investment advisor since its organization in 1976.
Today, the advisor, together with its subsidiaries, advises or manages over 110
investment portfolios, including the fund, encompassing a broad range of
investment objectives.

rate of 1.00% of the fund's daily average net assets.

                     --------------------------------------
 
OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares at the fund's
next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.
 
  The fund currently offers shares only to insurance company separate accounts.
In the future, the fund may offer them to pension and retirement plans that
qualify for special federal income tax treatment.
 
  The Board of Directors monitors for possible conflicts among separate accounts
(and will do so for plans) buying shares of the fund. A fund's net asset value
could decrease if it had to sell investment securities to pay redemption
proceeds to a separate account (or plan) withdrawing because of a conflict.
 
PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.
 
TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisers before investing.
 
DIVIDENDS AND DISTRIBUTIONS

DIVIDENDS
 
The fund generally declares and pays dividends, if any, annually to separate
accounts of participating life insurance companies.

CAPITAL GAINS DISTRIBUTIONS
 
The fund generally distributes long-term and short-term capital gains (including
any net gains from foreign currency transactions), if any, annually to separate
accounts of participating life insurance companies.
 
  At the election of participating life insurance companies, dividends and
distributions are automatically reinvested at net asset value in shares of that
fund.

                                       reference.
 
                                       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. There is a risk
                                       that you could lose a portion or all
                                       of your money.
 
                                       As with all other mutual fund
                                       securities, the Securities and
                                       Exchange Commission has not approved
                                       or disapproved these securities or
                                       determined whether the information
                                       in this prospectus is adequate or

                        AIM V.I. GROWTH AND INCOME FUND
                        -------------------------------
 
INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's primary investment objective is growth of capital with a secondary
objective of current income.
 
  The fund seeks to meet these objectives by investing at least 65% of its net
assets in income-producing securities, including dividend-paying common stocks
and convertible securities. The portfolio managers purchase securities of
established companies that have long-term above-average growth in earnings and
dividends, and growth companies that they believe have the potential for
above-average growth in earnings and dividends. The fund may invest up to 20% of
its total assets in foreign securities. The portfolio managers sell a particular
security when they believe the security no longer has that potential or the
capacity to generate income.
 
  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 and brokerage commissions, both of which can
lower the actual return on your investment.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instruments, bonds or other
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 and that the income you may receive from your investment may vary. 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 price 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 values of the convertible
securities in which the fund may invest also will be affected by market interest
rates, the risk that the issuer may default on interest or principal payments
and the value of the underlying common stock into which these securities may be
converted. Specifically, since these types of convertible securities pay fixed
interest and dividends, their values may fall if market interest rates rise and
rise if market interest rates fall. Additionally, an issuer may have the right
to buy back certain of the convertible securities at a time and at a price that
is unfavorable to the fund.
 
  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.

  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.
 
These factors may affect the prices of securities issued by foreign companies
located in developing countries more than those in countries with mature

FUND MANAGEMENT
- --------------------------------------------------------------------------------
 
THE ADVISOR
 
A I M Advisors, Inc. (the advisor) serves as the fund's investment advisor. The
advisor is located at 11 Greenway Plaza, Suite 100, Houston, Texas 77046-1173.
The advisor supervises all aspects of the fund's operations and provides
investment advisory services to the fund, including obtaining and evaluating
economic, statistical and financial information to formulate and implement
investment programs for the fund.
 
  The advisor has acted as an investment advisor since its organization in 1976.
Today, the advisor, together with its subsidiaries, advises or manages over 110
investment portfolios, including the fund, encompassing a broad range of
investment objectives.

ADVISOR COMPENSATION
 
During the fund's last fiscal year ended December 31, 1998, the advisor received
compensation of 0.61% of the fund's average net assets.
 
PORTFOLIO MANAGERS
 
The advisor uses a team approach to investment management. The individual
members of the team who are primarily responsible for the day-to-day management
of the fund's portfolio, all of whom are officers of A I M Capital Management,
Inc., a wholly owned subsidiary of the advisor, are
 
- - Lanny H. Sachnowitz, Senior Portfolio Manager, who has been responsible for
  the fund since 1994, and has been associated with the advisor and/or its
  affiliates since 1987.
 
- - Brant H. DeMuth, Portfolio Manager, who has been responsible for the fund
  since 1998, and has been associated with the advisor and/or its affiliates
  since 1996. From 1992 to 1996, Mr. DeMuth was portfolio manager for Colorado
  Public Employee Retirement Association.
 
OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares at the fund's
next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.

PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.

TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisors before investing.

DIVIDENDS AND DISTRIBUTIONS

DIVIDENDS
 
The fund generally declares and pays dividends, if any, annually to separate
accounts of participating life insurance companies.

CAPITAL GAINS DISTRIBUTIONS
 
The fund generally distributes long-term and short-term capital gains (including
any net gains from foreign currency transactions), if any, annually to separate
accounts of participating life insurance companies.
 
  At the election of participating life insurance companies, dividends and
distributions are automatically reinvested at net asset value in shares of the
fund.

                            ------------------------
                            AIM V.I. HIGH YIELD FUND
                            ------------------------
 
INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's investment objective is to achieve a high level of current income.
The fund's investment objective may be changed by the fund's Board of Directors
without shareholder approval.
 
  The fund seeks to meet this objective by investing at least 65% of the value
of its assets in publicly traded, lower-quality debt securities, i.e., "junk
bonds." The fund will primarily invest in junk bonds rated B or above by Moody's
Investors Services, Inc. or Standard & Poor's Rating Services or deemed by the
portfolio managers to be of comparable quality. The fund will invest at least
80% of its total assets in debt securities, including convertible debt
securities and/or cash or cash equivalents. The fund may also invest in
preferred stock. The fund may invest up to 25% of its total assets in foreign
securities.
 
  Although the portfolio managers focus on debt securities that they believe
have favorable prospects for high current income, they also consider the
possibility of growth of capital of the security. The portfolio managers
consider whether to sell a particular security when any of those factors
materially changes.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instruments, bonds or other
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 and that the income you may receive from your investment may vary. 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, 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. Interest
rate increases can cause the price of a debt security to decrease. Junk bonds
are less sensitive to this risk than are higher-quality bonds.
 
  Compared to higher-quality debt securities, junk bonds involve greater risk of
default or price changes due to changes in the credit quality of the issuer
because they are generally unsecured and may be subordinated to other creditors
claims. The value of junk bonds often fluctuates in response to company,
political or economic growth developments and can decline significantly over
short periods of time or during periods of general or regional economic
difficulty. During those times, the bonds could be difficult to value or to sell
at a fair price. Credit ratings on junk bonds do not necessarily reflect their
actual market 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 more volatile than U.S. securities.
 
These factors may affect the prices of securities 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 devaluated 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 its systems and to obtain

FUND MANAGEMENT
- --------------------------------------------------------------------------------
 
THE ADVISOR
 
A I M Advisors, Inc. (the advisor) serves as the fund's investment advisor. The
advisor is located at 11 Greenway Plaza, Suite 100, Houston, Texas 77046-1173.
The advisor supervises all aspects of the fund's operations and provides
investment advisory services to the fund, including obtaining and evaluating
economic, statistical and financial information to formulate and implement
investment programs for the fund.
 
  The advisor has acted as an investment advisor since its organization in 1976.
Today, the advisor, together with its subsidiaries, advises or manages over 110
investment portfolios, including the fund, encompassing a broad range of
investment objectives.

ADVISOR COMPENSATION
 
The advisor is to receive a fee from the fund calculated at the annual rate of
0.625% of the first $200 million of average daily net assets, 0.55% of the next
$300 million of average daily net assets, 0.50% of the next $500 million of
average daily net assets and 0.45% of average daily net assets over $1 billion.

PORTFOLIO MANAGERS
 
The advisor uses a team approach to investment management. The individual
members of the team who are primarily responsible for the day-to-day management
of the fund's portfolio, all of whom are officers of A I M Capital Management,
Inc., a wholly owned subsidiary of the advisor, are
 
- - John L. Pessarra, Senior Portfolio Manager, who has been responsible for the
  fund since 1998, and has been associated with the advisor and/or its
  affiliates since 1990.
 
- - Kevin E. Rogers, Senior Portfolio Manager, who has been responsible for the
  fund since 1998, and has been associated with the advisor and/or its

OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares at the fund's
next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.

PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.

TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisors before investing.

DIVIDENDS AND DISTRIBUTIONS

DIVIDENDS
 
The fund generally declares and pays dividends, if any, annually to separate
accounts of participating life insurance companies.

CAPITAL GAINS DISTRIBUTIONS
 
The fund generally distributes long-term and short-term capital gains (including
any net gains from foreign currency transactions), if any, annually to separate
accounts of participating life insurance companies.
 
  At the election of participating life insurance companies, dividends and
distributions are automatically reinvested at net asset value in shares of the
fund.

                                       This prospectus contains important
                                       information. Please read it before

                                       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. There is a risk
                                       that you could lose a portion or all

                       ----------------------------------
                       AIM V.I. INTERNATIONAL EQUITY FUND
                       ----------------------------------
 
INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's investment objective is to provide long-term growth of capital by
investing in a diversified portfolio of international equity securities whose
issuers are considered to have strong earnings momentum.
 
  The fund seeks to meet this objective by investing at least 70% of its total
assets in marketable equity securities of foreign companies that are listed on a
recognized foreign securities exchange or traded in a foreign over-the-counter
market. The fund will normally invest in companies located in at least four
countries outside of the United States, emphasizing investment in companies in
the developed countries of Western Europe and the Pacific Basin. The fund may
invest up to 20% of its total assets in securities of issuers located in
developing countries, i.e., those that are in the initial stages of their
industrial cycles. The fund may invest up to 20% of its total assets in
securities exchangeable for or convertible into equity securities of foreign
companies.
 
  The portfolio managers focus on companies that have experienced above-average,
long-term growth in earnings and have strong prospects for future growth. In
selecting countries in which the fund will invest, the portfolio managers also
consider such factors as the prospect for relative economic growth among
countries or regions, economic or political conditions, currency exchange
fluctuations, tax considerations and the liquidity of a particular security. The
portfolio managers consider whether to sell a particular security when any of
those factors materially changes.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instruments, bonds or other
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, the value of its assets, general economic
conditions, interest rates, investor perceptions and market liquidity.
 
  The prices of foreign securities may be further affected by other factors,
including:
 
- - Currency exchange rates--The dollar value of the fund's foreign investment
  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.
 
These factors may affect the prices of securities 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 devaluated 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 its 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.

OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares at the fund's
next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.
 
PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.
 
TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisors before investing.
 
DIVIDENDS AND DISTRIBUTIONS

DIVIDENDS
 
The fund generally declares and pays dividends, if any, annually to separate
accounts of participating life insurance companies.

CAPITAL GAINS DISTRIBUTIONS
 
The fund generally distributes long-term and short-term capital gains (including
any net gains from foreign currency transactions), if any, annually to separate
accounts or participating life insurance companies.
 
  At the election of participating life insurance companies, dividends and
distributions are automatically reinvested at net asset value in shares of the
fund.

                        --------------------------------
 
INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's investment objective is long-term growth of capital.
 
  The fund seeks to meet this objective by investing primarily in equity
securities of companies throughout the world engaged in the development,
manufacture or sale of telecommunications services or equipment. The fund will
invest, normally, at least 65% of its total assets in common and preferred
stocks and warrants to acquire such stocks issued by telecommunications
companies. The fund considers a "telecommunications company" to be one that (1)
derives at least 50% of its revenues or earnings from telecommunications
activities, or (2) devotes at least 50% of its assets to such activities, based
on its most recent fiscal year. Such companies include those that develop,
manufacture, or sell communications services and equipment, computer and
electronic components and equipment, mobile communications, and broadcasting.
The fund may invest up to 35% of its assets in debt securities issued by
telecommunications companies and/or equity and debt securities of other
companies the portfolio managers believe will benefit from developments in the
telecommunications industry. The fund may also invest up to 5% of its total
assets in lower-quality debt securities, i.e., "junk bonds."
 
  The fund will normally invest in the equity 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 not invest more than 40% 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 managers allocate the fund's assets among countries, sectors and
in currency denominations that are expected to provide the best opportunities
for long-term growth of capital. The portfolio managers consider whether to sell
a particular security when any of those factors materially changes.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instruments, bonds or other
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 common stocks 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
the telecommunications industry, such as substantial government regulation.
Because the fund focuses its investments in the telecommunications industry, the
value of your fund shares may rise and fall more than the value of shares of a
fund that invests more broadly.
 
  In addition, the prices of securities issued by 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 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.
 
  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 its 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.

OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares at the fund's
next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.
 
PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.
 
TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisers before investing.
 
DIVIDENDS AND DISTRIBUTIONS

DIVIDENDS
 
The fund generally declares and pays dividends, if any, annually to separate
accounts of participating life insurance companies.

CAPITAL GAINS DISTRIBUTIONS
 
The fund generally distributes long-term and short-term capital gains (including
any net gains from foreign currency transactions), if any, annually to separate
accounts of participating life insurance companies.
 
  At the election of participating life insurance companies, dividends and
distributions are automatically reinvested at net asset value in shares of that
fund.

        PROSPECTUS
        MAY 3, 1999
 
                                     This prospectus contains important
                                     information. Please read it before
                                     investing and keep it for future
                                     reference.
 
                                     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. There is a risk
                                     that you could lose a portion or all
                                     of your money.
 
                                     As with all other mutual fund
                                     securities, the Securities and
                                     Exchange Commission has not approved
                                     or disapproved these securities or
                                     determined whether the information in
                                     this prospectus is adequate or
                                     accurate. Anyone who tells you
                                     otherwise is committing a crime.

                              AIM V.I. VALUE FUND
                              -------------------
 
INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------
 
The fund's investment objective is to achieve long-term growth of capital by
investing primarily in equity securities judged by the fund's investment advisor
to be undervalued relative to the investment advisor's appraisal of the current
or projected earnings of the companies issuing the securities, or relative to
current market values of assets owned by the companies issuing the securities or
relative to the equity market generally. Income is a secondary objective.
 
  The fund also may invest in preferred stocks and debt instruments that have
prospects for growth of capital. The fund also may invest up to 25% of its total
assets in foreign securities.
 
  The portfolio managers focus on undervalued equity securities of (1)
out-of-favor cyclical growth companies; (2) established growth companies that
are undervalued compared to historical relative valuation parameters; (3)
companies where there is early but tangible evidence of improving prospects that
are not yet reflected in the price of the company's equity securities; and (4)
companies whose equity securities are selling at prices that do not reflect the
current market value of their assets and where there is reason to expect
realization of this potential in the form of increased equity values. The
portfolio managers consider whether to sell a particular security when they
believe the company no longer fits into any of the above categories.
 
  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the fund may temporarily hold
all or a portion of its assets in cash, money market instrument, bonds or other
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 and that the income you may receive from your investment may vary. 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 price 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 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.
 
These factors may affect the prices of securities 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 devaluated 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.
 
  If the seller of a repurchase agreement in which the fund invests defaults on
its obligation or declares bankruptcy, the fund may experience delays in selling
the securities underlying the repurchase agreement. As a result, the fund may
incur losses arising from decline in the value of those securities, reduced
levels of income and expenses of enforcing its rights.
 
  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 its 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.

OTHER INFORMATION
- --------------------------------------------------------------------------------
 
PURCHASE AND REDEMPTION OF SHARES
 
The fund ordinarily effects orders to purchase and redeem shares at the fund's
next computed net asset value after it receives an order. Life insurance
companies participating in the fund serve as the fund's designee for receiving
orders of separate accounts that invest in the fund.
 
PRICING OF SHARES
 
The fund prices its shares based on its net asset value. The fund values
portfolio securities for which market quotations are readily available at market
value. The fund values short-term investments maturing within 60 days at
amortized cost, which approximates market value. The fund values all other
securities and assets at their fair value. Securities and other assets quoted in
foreign currencies are valued in U.S. dollars based on the prevailing exchange
rates on that day. In addition, if, between the time trading ends on a
particular security and the close of the New York Stock Exchange (NYSE), events
occur that materially affect the value of the security, the fund may value the
security at its fair value as determined in good faith by or under the
supervision of the Board of Directors. The effect of using fair value pricing is
that the fund's net asset value will be subject to the judgment of the Board of
Directors or its designee instead of being determined by the market. Because the
fund may invest in securities that are primarily listed on foreign exchanges,
the value of the fund's shares may change on days when the separate account will
not be able to purchase or redeem shares. The fund determines the net asset
value of its shares as of the close of the NYSE on each day the NYSE is open for
business.
 
TAXES
 
The amount, timing and character of distributions to the separate account may be
affected by special tax rules applicable to certain investments purchased by the
fund. Holders of variable contracts should refer to the prospectus for their
contracts for information regarding the tax consequences of owning such
contracts and should consult their tax advisors before investing.
